Description
BACKGROUND
This invention relates to providing an improved shutter system for
reduction of light emission into a building. Shutters generally
utilizing pivoting louvers or slats for controlling the amount of
light entering through a building light opening, such as a window or
door, are well known (see, e.g., U.S. Pat. Nos. 4,974,362 and
5,020,276). Such louvers typically consist of a blade or wing
construction with two thinner-edged, longer longitudinal sides,
separated by a thicker middle portion between them and two shorter
transverse ends.
Typically, such shutters have a plurality of such pivoting louvers
connected to a rectangular frame. The frame typically consists of
two side members referred to in the art as stiles and a top and
bottom member referred to in the art as rails. The louvers are
connected together by a tilt rod such that they may be moved in
unison. The tilt rod is typically a U-cross-section wooden rod which
has staples inserted into the flat portion of the rod, which are
coupled to staples inserted into one surface of a longitudinal side
of the louver. Typically, the tilt rod is inserted on the front face
of the shutter, the front face of the shutter being defined herein
as that portion of the shutter facing away from the outside light
entry, such as through a window.
Such louvers are typically connected to the rectangular frame such
that the longitudinal sides of the louvers are substantially
horizontal or in line with the rails. Typically, the shutter is
considered in a closed position when the tilt rod is in its most
upward position and the louvers are slanted in a substantially
vertical position slightly overlapping each other. The shutter is
considered in a fully open position when the louvers are in a
substantially horizontal position with no overlap. The louvers are
adjustable and may be partially opened to allow varying amounts of
light to pass through them.
The present invention relates generally to shutters in which the
louvers are arranged such that the louvers never extend beyond the
plane of the rear face of the frame (as referenced in U.S. Pat. No.
4,974,362), the rear face of the shutter being defined herein as the
face opposing the front face. One of the problems with prior art
shutters is that light penetrates through and around the shutter
even when closed. One of these areas subject to such penetration is
the area between the louver and the shutter frame. Another area that
light penetrates through and around is along the side of a shutter
such as when a shutter is covering a French door window. Yet another
area of light penetration is in the framing around arched shutters
that are used to cover arched windows.
OBJECTS OF THE INVENTION
A primary object and feature of the present invention is to overcome
the above-stated problems of the prior art.
It is a primary object and feature of the present invention to
provide a system for reducing the light passing through gaps at the
junction between the louvers and the frame of a shutter when the
louvers are in the closed position.
Another object and feature of the present invention is to provide a
system for reducing the light passing through the side of a shutter
covering a French door window lite (i.e., pane of glass).
Yet another object and feature of the present invention is to
provide a system for reducing the light passing through gaps at the
framing of arched shutters.
A still further object and feature of this invention is to provide a
novel and useful method of making shutters with such improved
features.
It is a further object and feature of the present invention to
provide such a system which is aesthetically pleasing, while
minimizing light entry through the shutter.
A further primary object and feature of the present invention is to
provide such a system which provides an improved system for
maintaining the louvers in a user selected position.
A further primary object and feature of the present invention is to
provide such a system which is efficient, inexpensive, and handy.
Other objects and features of this invention will become apparent
with reference to the following descriptions.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
Referring now to the drawings, FIG. 1 is a perspective view of the
rear face 122 (embodying herein a first face lying substantially in
a first plane) of the shutter system 120 according to a preferred
embodiment of the present invention. FIG. 3 is a front view of the
rear face 122 of the shutter 124 of FIG. 1 according to a preferred
embodiment of the present invention. Preferably, shutter 124
(embodying herein a shutter structured and arranged to regulate
entry of the light into the building) comprises two vertical members
or stiles 126 and 128, two horizontal members or rails, a top rail
130 and a bottom rail 132. Preferably, the stiles 126 and 128 and
rails 130 and 132 are joined together (e.g. by stapling, nailing,
gluing and/or use of a joiner tool) to form a rectangular frame 134
(embodying herein a shutter frame structured and arranged to
positionally support such shutter; and, frame means for positionally
supporting such louver means) having an outside peripheral frame
edge 135 and an inside peripheral frame edge 137, having a hollow
middle portion 139 (best viewed in FIG. 6)(embodying herein wherein
such shutter frame comprises at least one outside peripheral frame
edge, at least one inside peripheral frame edge, a hollow middle
area substantially equal in size to an area of light regulation by
such slats of such shutter). Under appropriate circumstances, other
arrangements may suffice. For example, under appropriate
circumstances, the shutter may be square, triangular, or another
custom-shape.
Preferably, the shutter 124 also comprises several louvers 136
(embodying herein louver means for selectively regulating entry of
the light into the building) which are preferably housed within the
hollow middle portion 139 (referring to the space within the
rectangular frame 134 when no louvers 136 are present) of the
rectangular frame 134 (the above arrangement embodies herein a
hollow middle area substantially equal in size to an area of light
regulation by such slats of such louver means; and also embodies
herein a hollow middle area substantially equal in size to an area
of light regulation by such slats of such shutter). Preferably,
louvers 136 are slats having a pair of longitudinal edges 151 and
two ends 153, each having a transverse edge pivotally attached to
the stiles 126 and 128 (embodying herein wherein such louver means
comprises a plurality of slats, each such slat comprising a pair of
longitudinal edges, at least one slat end portion, each such slat
end portion having a transverse edge). Preferably, the louvers 136
are arranged such that each transverse edge is adjacent the inside
peripheral edge 137 (embodying herein such shutter and shutter frame
being structured and arranged to provide that at least one such
transverse edge is adjacent such at least one inside peripheral
frame edge of such shutter frame).
Preferably, the shutter system 120 uniquely adds the use of a
light-blocking element 140 (embodying herein blocking means and a
blocker) attached to each stile 126 and 128, as shown. Preferably,
the light-blocking element 140 is a rectangular cross-section-rod,
as shown (embodying herein wherein such blocking means comprises a
rectangular-cross-section rod). In most shutters, closing the
shutter 124 or moving the louvers 136 to a position in which they
overlap each other, significantly reduces the light passing through
the shutter 124. The light-blocking element 140 further assists the
light-blocking process of the shutter 124 by blocking light passing
through the junction 138 between the louvers 136 and the frame 134
(viewed best in FIG. 8) (this arrangement embodies herein a light
blocker structured and arranged to block substantially all the entry
of the light adjacent at least one such slat end portion adjacent
such at least one inside peripheral frame edge; and, embodies herein
blocking means for blocking substantially all the entry of the light
adjacent at least one such slat end portion adjacent such at least
one inside peripheral frame edge). Such a light-blocking element 140
only works in conjunction with a shutter 124 in which the louvers
136 are arranged such that the louvers 136 never (in any louver
position) extend beyond the plane of the rear face 122 of the frame
134 (embodying herein locating means for locating such louver means
so that at least one such transverse edge is adjacent such at least
one inside peripheral frame edge of such frame means, and no such
longitudinal edges at such slat end portions extend beyond about
such plane of such first face of such frame means; and embodying
herein such shutter and shutter frame being structured and arranged
to provide that at least one such transverse edge is adjacent such
at least one inside peripheral frame edge of such shutter frame, and
no such longitudinal edges at such slat end portions extend beyond
about such plane of such first face of such shutter frame). Use of a
center pivoting louver, (for example, as described in U.S. Pat. No.
5,020,276) would not function with such a light blocking element 140
as the louvers 136 would collide with the light blocking element
140.
FIG. 2 is a perspective view of the front face 142 (embodying herein
a second face opposing such first face and lying substantially in a
second plane substantially parallel to such first plane) of the
shutter system 120 according to a preferred embodiment of the
present invention. FIG. 4 is a front view of the front face 142 of
the shutter 124 of FIG. 2 according to a preferred embodiment of the
present invention.
FIG. 5 is a sectional view 150, partially in section, through
section 5--5 of FIG. 3, illustrating the louvers 136 in a closed
position. FIG. 6 is a sectional view 152, partially in section,
similar to FIG. 5 but illustrating the louvers 136 in an open
position. FIG. 7 is a sectional view, partially in section, of Area
7 of FIG. 5 illustrating the connection between tilt rod 144 and
louver 136.
More detailed reference is now made to the above-described Figures.
Preferably, the louvers 136 are connected together by a tilt rod 144
(embodying herein a tilt rod structured and arranged to operate such
shutter; and, tilt rod means for operating such louver means) such
that the louvers 136 may be moved in unison. The tilt rod 144 is
preferably a U-shaped wooden rod. Preferably, the tilt rod 144 is
connected to each of the louvers 136 utilizing a first staple 146 in
the louver 136 and a second staple 148 on the tilt rod 144
(embodying herein staple means for using staples to connect such
tilt rod means to such louver means, wherein such staple means
comprises at least one first staple penetrating at least one such
slat of such louver means, and at least one second staple
penetrating such tilt rod means; and, staples structured and
arranged to connect such tilt rod to such shutter, at least one
first staple penetrating at least one such slat of such shutter, and
at least one second staple penetrating such tilt rod). Preferably,
the staples 148 are inserted into the flat portion 149 of the tilt
rod 144, staples 148 being preferably coupled to staples 146
inserted into one longitudinal edge 151 of a longitudinal side of
the louver 136 forming a pivotal interlocking attachment (embodying
herein wherein such first and second staples comprise a pivotable
interlocking attachment between such first and second staples).
Preferably, the tilt rod 144 is positioned on the front face 142 of
the shutter. Typically, in the prior art, a one-half inch staple
penetration is utilized. However, in the present preferred shutter
system 120, the louver 136 and tilt rod 144 preferably will accept
up to about one-inch long staple penetration. Under appropriate
circumstances, other size staples may suffice, however, the
preferred one-inch staple is durable and provides a firm connection
which is not easily removed.
Preferably, both the first staple 146 and the second staple 148
penetrate their respective louver 136 and tilt rod 144 about one
inch (this arrangement embodies herein wherein penetration of such
slat by such first staple is about one inch, and wherein penetration
of such tilt rod means by such second staple is about one inch). The
additional penetration of the staples 146 and 148 reduces
instability common in prior art tilt-rod-to-louver connections that
occurs over an extended period of use. Specifically preferred herein
is to use a tilt rod about 1/8" deeper than typical and use one-inch
long staples in the tilt rod, providing a penetration of the staple
of about 7/8"; and to use also a crown staple for the louver, the
staple being sized at 13/8' long, providing a penetration of about
11/4" (this making up for the thinness of the louver and better
resisting breakage). Also, it is noted that, for best results, the
spacing of the staples along the tilt rod should follow the same
formula as the pivot hole spacing herein described.
Preferably, shutter system 120 utilizes a louver 136 that is pivoted
such that no part of the louver 136 passes the plane of the rear
face 122 of the shutter 124 as shown in FIG. 6. This is preferred as
the light blocking element 140 is preferably attached to the stiles
126 and 128 such that the light blocking element 140 is flush with
the plane of the rear face 122 of the shutter 124. Under appropriate
circumstances, positions of the light-blocking element 140 other
than flush with the plane of the rear face 122 may suffice, however,
they are not preferred.
Preferably, in order to prevent light from passing through the
shutter at the intersection of the louvers 136 and the top rail 130,
as well as the louvers 136 and the bottom rail 132, when in the
closed position 150, a portion of the top rail 130 and the bottom
rail 132 is removed. This type of removed area is commonly called a
"rabbit" relief in the woodworking art but will be referred to
herein as a recess 154 for the top rail 130 and recess 156 for the
bottom rail 132 (best illustrated in FIG. 5 and FIG. 6). The wood
remaining after these recesses are routed out act as bottom and top
light blocking elements. Preferably, the louvers 136 rest within the
recess 154 and 156 when in the closed position 150. Preferably, the
vertical height of the recesses 154 and 156 is about one-half inch.
Preferably, the use of the recesses 154 and 156 in combination with
the light blocking element 140 provides for a much improved shutter
system 120 and reduction of light passing through the shutter 124
when in the closed position 150.
FIG. 8 is a sectional view through section 8--8 of FIG. 3; and FIG.
11 is a perspective view, partially in section, illustrating an
exploded view of a louver 136, light stop 140, louver attachment pin
158 and stiles 126 and 128. Illustrated in section in FIG. 8 and in
perspective in FIG. 11 is the preferred arrangement of the louver
136, light stop 140 and louver attachment pin 158 to the stiles 126
and 128. Preferably, stiles 126 and 128 are equal in width as
indicated by Dimension W and Dimension W', where Dimension W is
equal to Dimension W' (embodying herein such shutter frame comprises
at least two stiles of approximately equal shape). Louvers 136 are
attached pivotally to the stiles 126 and 128 by use of pins 158
which are preferably inserted into both the louver 136 and the
respective stiles 126 and 128, as shown. Preferably, the shutter
system 120 also comprises at least one set of center-mounted
resistors, preferably friction pins, which assist in maintaining an
angular position of the louvers. Alternate embodiments of such
center-mounted resistors are described in reference to FIG. 31
through FIG. 35 below.
Preferably, light blocking element 140 is attached, as shown, to
each respective stile 126 and 128 such that light blocking element
140 is flush with the rear face and will block any light passing
through junction 138 (this arrangement embododies herein a light
blocker structured and arranged to block substantially all the entry
of the light adjacent at least one such slat end portion adjacent
such at least one inside peripheral frame edge; wherein such first
face of such shutter frame comprises such blocker; and wherein such
blocker is located along such at least one inside peripheral frame
edge; and wherein such blocker extends inwardly from such at least
one inside peripheral frame edge toward such hollow middle; and,
also embodies herein blocking means for blocking substantially all
the entry of the light adjacent at least one such slat end portion
adjacent such at least one inside peripheral frame edge; wherein
such first face of such frame means comprises such blocking means;
and wherein such blocking means is located along such at least one
inside peripheral frame edge; and wherein such blocking means
extends inwardly from such at least one inside peripheral frame edge
toward such hollow middle). Preferably, the above attachment of
light blocking element 140 to each respective stile 126 and 128 is
made by using glue and wood staples. Under appropriate
circumstances, other methods of attachment may suffice.
Another feature of the shutter system 120 is that the top rail 130
and the bottom rail 132 are preferably made in equal dimensions
(height and width). FIG. 4 illustrates the preferred Height R and
Height R', where Height R is equal to Height R' (this arrangement
embodies herein at least two rails of approximately equal shape). In
order to make the shutter 124 with equal height top rail 130 and
bottom rail 132, it is necessary to arrange the louvers 136 in a
custom manner with a custom-dimensioned (for each measured job)
Overlap O (shown in FIG. 7). Typically, prior art louvers are
pre-assembled in the stiles 126 and 128 in set lengths, and arranged
depending on the louver height in increments that are equal in
Overlap O. For example, a three and one-half inch wide louver (front
to rear dimension) would typically have about a one-half inch
Overlap O. The spacing for the holes 160 (shown only in FIG. 11) in
which the pin 158 is placed in the stiles 126 and 128 would
preferably be three inches in the above example (three and one-half
inches less a one-half inch overlap). Preferably, determining the
number of louvers needed to cover the distance between the top and
bottom rails, Distance L, is determined by a simple formula as
follows: The Distance L between the top and bottom rails divided by
the Louver width less one-half inch (the preferred overlap) which
equals the No. of louvers.
For example, if the distance L (FIG. 4) is 30" and the louver 136
width is 31/2", then 30" divided by (3.5" minus 0.5") equals 10.
Therefore, in this example, there are ten 3.5" louvers 136 necessary
to cover the space between the top rail 130 and the bottom rail 132
(Distance L) with a one-half inch overlap. Typically, when producing
a shutter 124 for a building opening such as a window, the shutter
124 dimensions are determined and the shutter 124 is made by
determining how many louvers 136 are needed and what size the top
rail 130 and the bottom rail 132 will be to accommodate the use of
the pre-assembled louvers 136/stiles 126 and 128 sub-assembly.
Typically, the pre-assembled louvers 136/stiles 126 and 128
sub-assembly are attached to the bottom rail 132 and then cut-off at
the top and the top rail 130 is attached. Unless by accident, the
top rail 130 and the bottom rail 132 are not equal in their
dimension. The present invention provides manufacturing the top rail
30 and the bottom rail 132 such that they are always equal in
dimension.
In a preferred embodiment of a method of manufacturing the shutter
124 of the present invention, the window distance from top to bottom
of the opening is measured (embodying herein providing measurements
of a rectangular area to be covered by a shutter). Preferably, a top
rail 130 and bottom rail 132 are provided along with selection of
the louver 136 size and a pair of stiles 172 and 174 are selected
(the above arrangement embodies herein providing horizontal louvers
of a selected standardized size; providing a pair of shutter side
panels (stiles) of substantially equal size and permitting use of
such louvers; providing a pair of shutter end panels (rails) of
substantially equal size and having about the same width as such
louvers). Preferably, the top rail 130 and the bottom rail 132
dimension is subtracted (as they are equal in dimension). Then the
distance L (FIG. 4) is determined and the number of louvers 136 is
figured utilizing the above-described formula (embodying herein
determine a number of louvers adequate to regulate light entry
through a height approximately equal to the stile height less twice
the rail height, assuming a desired minimum overlap between
louvers). Preferably, if the number of louvers 136 is not exact the
number is rounded down or up to the nearest whole number. The
remaining louvers 136 are then spaced equally between the top rail
130 and the bottom rail 132 in a custom installation unlike the
prior art installation method. The holes 160 are custom drilled into
the stiles 126 and 128 (this arrangement embodies herein determine
an actual louver vertical spacing, assuming equal overlaps between
louvers; providing an appropriate number and spacing of louver pivot
locations along an inside of each such stile). In order to determine
the starting position of the top louver and the bottom louver pin
158 holes, a simple scribe tool 162 is used. Such a scribe tool 162
is illustrated in FIG. 9 and FIG. 10.
FIG. 9 is a perspective view, partially in section, illustrating a
method of measuring the top louver placement in the shutter frame
according to a preferred embodiment of the present invention. FIG.
10 is a perspective view, partially in section, illustrating a
method of measuring the bottom louver placement in the shutter frame
according to a preferred embodiment of the present invention.
Preferably, the scribe tool 162 is used to assist in the placement
of the first louver pin hole 164 (see FIG. 5) placed below the top
rail 130 of the shutter 124 and the final bottom louver pin hole 166
(see FIG. 6) placed above the bottom rail 132 of the shutter 124.
Preferably, the louver pinhole 164 allows for the top louver to
tightly fit into recess 154 when in the closed position 150.
Preferably, the placement of the louver pinhole 164 is calculated
as: the height of the top rail, plus one-sixteenth inches, plus the
width of the louver, minus one-half the thickness of the louver.
Preferably, louver pinhole 166 allows for the bottom louver to
tightly fit into recess 156 when in the closed position 150.
Preferably, the placement of the louver pinhole 166 is calculated
as: the height of the bottom rail, plus one-sixteenth inches, plus
one-half the thickness of the louver. Preferably, the remaining
louvers 136 are then equally spaced apart. Preferably, the spacing
is such that the louvers 136 have an overlap which is more or less
within about one-eighth of an inch of the desired one-half inch. In
the above example of ten louvers there would be eight remaining
middle louvers 136 allowing for an adjustment of at least an inch
(1/8-inch times 8 louvers equal one inch) of space (to make up the
difference between an extra louver 136 or one less louver 136 in the
rounding process described above). Under appropriate circumstances,
other arrangements may suffice. Preferably, light blocking element
140 is attached, as shown, lastly, to each respective stile 126 and
128 such that light blocking element 140 is flush with the rear face
and will block the light between the louver end 153 and the inside
peripheral edge 137 (embodying herein assembling such shutter so as
to provide a light blocker along an inside edge of each such stile
structured and arranged to block entry of outside light between a
louver end and an inside edge of a stile).
Reference is now made to FIG. 12 and FIG. 13. FIG. 12 is a front
view of a dual shutter 168 according to a preferred embodiment of
the present invention. FIG. 13 is a sectional view through section
13--13 of FIG. 12. Typically, shutters 124 are limited in width; and
in building openings that are greater than about 24 inches; it is
preferable to utilize a multiple shutter arrangement such as the
dual shutter 168 shown in FIG. 12. When such a shutter 168 is used,
it is preferably comprised of two or more smaller width shutters 24.
The present invention provides that the front face 170 of the stiles
172 and 174 is such that both the stiles 172 and 174 appear to be
about equal in width X and X'. This "equalness" is accomplished by
simply elongating one of the stile ends 176 about one-quarter of an
inch such that the stile 172 is slightly longer and will overlap the
other stile 176, as shown (FIG. 13). Under appropriate
circumstances, other overlap arrangements may suffice. Preferably,
stile 172 and stile 174 each have a respective recess (rabbit cut)
178 and 179 into which the opposite stile will fit flush, as shown.
This an improvement over the prior art method of making both stiles
identical and using perhaps a "bead" on the edge of the larger front
stile face adjacent to the smaller style to hide the otherwise
apparent lack of "equalness".
Reference is now made to FIG. 14 and FIG. 15. FIG. 14 is an exploded
perspective view, partially in section, illustrating a door lite
(pane) shutter 124 and light blocking frame 180 according to a
preferred embodiment of the present invention.
FIG. 15 is a sectional view through section 15--15 of FIG. 14. This
embodiment allows for a further light blocking feature of the
present invention, that being a light blocking frame 180 as
illustrated in FIG. 14 and FIG. 15. Preferably, light blocking frame
180 is utilized on doors 186 which have an exterior molding 182
surrounding the light opening 184, such as French doors. Preferably,
frame 180 is a solid unitary frame 180, molded of wood and formed,
as shown, such that the frame 180 comprises a recess 188 which
effectively encompasses the molding 182, thus blocking light from
passing around the frame 180. Under appropriate circumstances, other
arrangements may suffice. For example, the frame may not be unitary.
Preferably, frame 180 also is structured and arranged, as shown,
such that shutter 124 is attached to the frame 180 and the frame is
attached to the door 186 (the above arrangement embodies herein
frame means for positionally supporting a shutter; encasing means
for encasing the molding in such manner as to permit the unitary
outer frame to be adjacent the inside of the French door and
adjacent such at least one glass pane; attachment means for
attaching such unitary outer frame to such French door; wherein such
encasing means and such frame means are opaque; whereby passage of
light adjacent the molding is restricted). Preferably, shutter 124
is hingedly attached to the frame 180 as illustrated by hinge 190.
The hinge 190 is preferred to provide access to the door light
opening 184 for cleaning and also for shutter 124 maintenance.
Reference is now made to FIG. 16. FIG. 16 is an exploded perspective
view of an arched frame 200, arched shutter 202 and sill 204 of a
wall-surface-mounted shutter system 206 of an arched shutter 202
according to another preferred embodiment of the present invention.
FIG. 17 is an exploded perspective view illustrating the multiple
parts of an arched frame 200 and sill 204 of the arched
wall-surface-mounted shutter system of FIG. 16.
Preferably, the arched wall-surface-mounted shutter system 206
comprises an arched shutter 202, an arched frame 200, and a sill
204. Preferably, the arched frame 200 comprises a facing arch 210, a
spacer 212 and a light stop 214. As illustrated in FIG. 19, the sill
204 preferably comprises a substantially horizontal bar member 216
and a light stop 218. Preferably, sill 204 is a unique feature in
the shutter art and is used in this embodiment of the present
invention to create a visual break (so that any slight differences
in the "matching" geometry above and below the sill is less
noticeable to the human eye) between the arched wall surface mounted
shutter system 206 and the shutter system 120 which is typically
installed in the normal rectangular portion of a window (this
arrangement embodying herein providing a sill as a bottom chord of
such arched shutter outer frame, whereby a viewer seeing a
"matching" rectangular shutter mounted directly below such sill will
be less able to distinguish small vertical misalignments).
Preferably, the arched frame 200 is attached to the sill 204 as
shown. Preferably, arched shutter 202 removably attaches within the
arched frame 200. Preferably, the arched shutter 202 removably
attaches within the arched frame 200 utilizing attaching hardware
220, which preferably comprises a button catch or a magnetic latch.
Preferably, the arched shutter 202 comprises an arch portion 222, a
bottom portion 224 and a louver portion 226. Preferably, the arched
wall-surface-mounted shutter system 206 mounts such that the arched
shutter 202 and the arched frame 200 are flush against the wall 203
framing the window opening (not shown).
In a preferred embodiment of the present invention, this invention
provides a method for producing an arched frame 200 and an arched
shutter 202 portion from a singular pattern 208, such as that
illustrated in FIGS. 20-22. In the prior art, the arched frame 200
and the arch portion 222 are made as separate pieces. The
improvement, in combination with the shutter system 120 of the
present invention, provides the facing arch 210 of the arched frame
200 and the arch portion 222 are made from a singular pattern 208,
as shown. FIG. 20 is a front view illustrating a manufacturing
step(s) in a method of making the facing arch 210 of the arched
frame 200 and the arch portion 222 for the arched shutter 202 of
FIG. 16 according to a preferred embodiment of the present
invention. Preferably, a pattern 208 is created utilizing the actual
interior window dimensions desired for placing the arched wall
surface mounted shutter system 206 in a position to cover the window
(building light opening).
Preferably, three portions 230, 232 and 234 are combined in a
pattern 208, as shown, such that an arch 236 may be cut from the
pattern 208 (embodying herein assembling, from at least one piece of
wood, a rough arch-shaped blank of desired size). Preferably, the
pattern 208 and arch 236 are made of wood and the portions 230, 232
and 234 are combined using glue and joining biscuits. Such combining
of wood is well known by those skilled in the art. Under appropriate
circumstances other materials and methods may suffice.
It is noted that the pivot locations for the arch louvers, similarly
as for the non-arched, must be located so that the arch louvers do
not break the plane of the shutter face, permitting the instant
light blocking.
FIG. 21 is a front view illustrating another step(s) in a method of
making the facing arch 210 of the arched frame 200 and the arch
portion 222 for the arched shutter 202 of FIG. 16. FIG. 21
illustrates the cutting out of the arch 236 (embodying herein
removing excess wood material to provide a substantially continuous
curved first arch-shaped piece having a desired first inner radius
and a desired first outer radius). FIG. 22 is a front view
illustrating yet another step(s) in a method of making the facing
arch 210 of the arched frame 200 and the arch portion 222 for the
arched shutter 202 of FIG. 16. FIG. 22 illustrates the preferred and
unique method of cutting two arches 238 and 240 from a single arch
236 (embodying herein making an arch-shaped cut through such first
arch-shaped piece in such manner as to provide a second arch-shaped
piece and a third arch-shaped piece, wherein such second arch-shaped
piece comprises such first outer radius and a second inner radius,
such third arch-shaped piece comprises such first inner radius and a
second outer radius, and such second inner radius is slightly more
than such second outer radius). This improvement permits arched
shutters of this type wherein the grains of the arches 238 and 240
are matched, a very useful end not accomplished by the prior art
method of making these arches out of separate pieces of wood
(embodying herein whereby such second and third arch-shaped pieces,
being adjacently located when such inner and outer frames are
assembled, will be closely matched in dimension and grain).
Preferably arch 238 becomes arch portion 222 for the arched shutter
202 (embodying herein using such third arch-shaped piece in the
manufacture of a surface mount arched shutter inner frame).
Preferably, arch 240 becomes facing arch 210 for the arched frame
200 (embodying herein using such second arch-shaped piece in the
manufacture of a surface mount arched shutter outer frame).
The next step in the method of making the arched
wall-surface-mounted shutter system 206 is to increase the thickness
of the facing arch 210 by preferably attaching a spacer 212 and a
light stop 214 to the facing arch 210, preferably by gluing 211 and
staples 213, as illustrated by FIG. 23 (also seen in perspective in
FIG. 17 and in section by FIG. 18). Preferably spacer 212 is an
about-one-sixteenth-inch-thick spacer, just enough to provide a
distance for the use of the attaching hardware 220 which preferably
has matching male-female parts which attaches the arched shutter 202
within the arched frame 200. The light stop 214 prevents light from
passing around the arch portion 222 of the arched shutter 202.
Preferably, the combined facing arch 210, spacer 212 and light stop
214 comprise the arched frame 200.
The next step in the method of making the arched
wall-surface-mounted shutter system 206 is to attach the arched
frame 200 to the sill 204 and preferably attach the female portion
of the attaching hardware 220, as shown. Further, the arch portion
222 is attached to the bottom portion 224 and shutter portion 226 to
comprise the arched shutter 202. Preferably, the arched shutter 202
is then connected to the arched frame 200 and sill 204 completing
the arched wall-surface-mounted shutter system 206. Under
appropriate circumstances, those knowledgeable in the art may add
additional painting, molding details, or other aesthetic features
without detracting from the functionality of the present invention.
Reference is now made to FIG. 24 through FIG. 30. In another
preferred embodiment of the present invention, this invention
provides a method for producing an arched portion 256 comprising
arched face frame portion 264, frame portion 266 and light stop 268.
The improvement, in combination with the shutter system 120,
provides a method for making the arched portion 256 from three
separate pieces as illustrated in FIG. 27.
FIG. 24 is a perspective view illustrating a Z-mount arched frame
250 and arched shutter 252 of an inside-window-mount arched shutter
254 according to another preferred embodiment of the present
invention. The inside-window-mount arched shutter 254 utilizes a
Z-type molding 255 as shown in FIG. 26. FIG. 26 illustrates the
Z-type molding 255, as it would be used for the bottom portion 259,
and side portions 258 and 260. The problem with this prior art
molding is that this type of molding cannot be used to make the
arched portion 256 of the frame 250. In the past, the arched portion
262 was made using a solid slab of wood. The slab of wood was cut in
an arch (using a similar method to that illustrated in FIG. 20). The
wood arch was then sawed by hand to remove the portion necessary to
be removed to allow the inside-window-mount arched shutter 254 to be
fitted against the wall 257 and inside ceiling 257' of the window
niche (not shown) as shown in FIG. 26. The old sawing procedure left
the arched portion 256 uneven and used additional labor and time
that the improved version does not (embodying herein whereby the
difficulties of cutting an approximate arched Z-shape from a single
arched blank of wood are reduced).
FIG. 27 illustrates, in section, the preferred embodiment of the
arched portion 256 comprising arched face frame portion 264, frame
portion 266 and light stop 268, as shown. Preferably, as illustrated
and discussed above in reference to FIG. 20 through FIG. 22 two
arched portion face frames 264 and 270 are made from a singular
pattern 208. Preferably, arched portion face frame 264 is used for
the Z-mount arched frame 250 (embodying herein using such second
arch-shaped piece in the manufacture of an upper portion of a
Z-mount arched shutter outer frame) and arched portion face frame
270 is used for arched shutter 252 (embodying herein using such
third arch-shaped piece in the manufacture of a Z-mount arched
shutter inner frame).
FIG. 25 is an exploded view of the arched frame 250 of FIG. 24.
Preferably, arched portion 256 comprises arched face frame portion
264, frame portion 266 and light stop 268. The improvement, in
combination with the shutter system 120, provides a method for
making the arched portion 256 from three separate pieces (embodying
herein assembling by attachment a three-part arched portion of such
Z-mount arched shutter outer frame; wherein a first part comprises
such second arch-shaped piece, a second part comprises a lower
height (than such first part) arch-shaped spacer mounted to the rear
of such first part, such second part having such second inner
radius, a third part comprises an arch-shaped light blocking element
mounted to the rear and below such second part, such assembled
three-part arched portion comprises an approximate Z-shape).
Preferably, arched portion face frame 264 is attached to a framing
member 272, preferably by gluing, as illustrated in FIG. 28.
Preferably, framing member 272 is sized to a depth that will allow
the shutter portion to fit within the arched frame 250, as shown in
FIG. 27.
Preferably, after attaching framing member 272 to the face frame
264, the assembly 276 is sanded such that the bottom 278 portion of
the two mated pieces, framing member 272 and face frame 264, are
smoothed. Preferably, as illustrated in FIG. 30, the light stop 274
is attached, again preferably by gluing to the assembly 276, as
shown. Finally, the arched portion 256 is attached to the bottom
portion 259, and side portions 258 and 260, creating the arched
frame 250.
Preferably, the shutter system 120 comprises a resistance system
280, which assists in maintaining an angular position of the louvers
136 after the louvers 136 have been positioned by a user. Three
embodiments of such resistance system 280 are now described in
reference to FIG. 31, FIG. 32, FIG. 33a, FIG. 33b and FIG. 33c.
FIG. 31 is a perspective view, partially in section, of a section of
louver 136 and stile 128 utilizing a resistance system 280,
according to a preferred embodiment of the present invention. FIG.
32 is a sectional view through section 32--32 of FIG. 31. FIG. 32
illustrates a prior art embodiment 282 for resistance systems 280,
as shown. In the illustrated embodiment 282, a screw 284 is used as
a louver-resister 280, as shown. Typically, a screw 284 used in such
manner only provides a minimal degree of resistance as the screw 284
is tightened down. The friction or tension in such use is limited to
the strength of the louver material 286 (typically wood) in the
louver 136 and the ability of such material 286 to hold the tension
of the screw threads 288 as they are tightened into the louver 136,
without stripping, which would cause the screw 284 to come loose,
thereby allowing the louvers 136 to free-fall when set and most
likely close shut. Typically, the screw used is a two and one-half
inch sheetrock-screw with fine threads. Under appropriate
circumstances, other arrangements may suffice. For example, a
smaller length screw may suffice or a screw with courser threads or
another style of screw such as a wood screw.
