Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to building structure and refers more
specifically to a prime window which is suitable for use as a
single-hung window, a hopper window, or a right or left-hand glider
window without modification of the basic window structure. The
window structure includes a box frame construction for strength and
appearance, constructed to prevent metal-to-metal contact in
operation whereby operation of the window structure is effected
without galling of the parts thereof, a unique mull cover for
mulling adjacent window structures, improved movable sash guide and
tilt release structure, movable sash guide and pivot structure,
movable sash lock structure, structure for maintaining the seal of
the movable sash in high winds, and improved weather stripping
structure along with unique installation clips and brackets for
economical, efficient installation of the window structure from
either the interior or exterior of a window opening.
2. Description of the Prior Art
In the past, window structure has generally been designed for a
single use. That is, it has been designed, for example, as a
single-hung window, as a hopper window, or as a glider window. Such
single-purpose windows require large dealer inventories to meet
demand for each type of window, which is undesirable. In addition,
multipurpose window structures of the past have generally had
complicated frame sections which were less strong and less
aesthetically pleasing than desirable. At times the frame sections
of previous window structures have had metal-to-metal contact in at
least one of their multiple uses whereby operation of the window
structure caused galling of the parts thereof and was noisy. Also,
the mulling of a plurality of multipurpose windows together in the
past has sometimes been difficult and unsatisfactory in
appearance.
In addition, the hardware of multipurpose window structures in the
past has generally been complicated and therefore expensive and
often inefficient. This is particularly true of sash guide and tilt
release structure, sash guide and pivot structure, sash balance
shoes, lock means for movable sash, hurricane clips and the
like.
Due to the requirement for movable sash of multipurpose window
structure to tilt freely so that the movable sash cannot run in
tracks in the window frame, multipurpose windows of the past have
been extremely difficult to seal tightly and weather stripping
therefor has often been inefficient. Installation of even
single-purpose windows in the past has usually not been possible
from the interior of a window opening and separate clips have
generally been required for installation of screens on both single
and multipurpose windows of the past.
In view of these deficiencies of prior window structures, a
multipurpose window structure in which the frame is strong and
aesthetically pleasing, is so constructed as to be easily mulled
and cause no galling of parts thereof in operation, and in which
sash guide and tilt release structure, sash guide and pivot
structure, sash balance and lock hardware are particularly simple
and therefore economical and efficient, is needed. To provide such
a multipurpose window wherein the window is easily sealed even with
regard to high-force winds yet has provision for weepage in all
positions of use thereof and which includes integral means for
securing a screen thereto and may be simply and rapidly installed
from either the interior or exterior of a window opening, is
therefore desirable.
SUMMARY OF THE INVENTION
In accordance with the invention, there is provided a universal
window structure which may be used as a single-hung window, as a
hopper window, and as a right or left-hand glider window without
alteration. The window structure of the invention includes a box
frame for strength and appearance including members contoured to
prevent metal-to-metal contact with the window structure in use so
that the window operates quietly and without galling. The window
structure of the invention further includes a mull cover which
permits a single workman to mull adjacent window structures.
Further, in accordance with the invention, the sash guide and tilt
release structure associated with a movable sash, sash guide and
pivot structure, as well as the sash balance shoe and movable sash
lock structure, are particularly simple, economical and efficient.
The window structure of the invention also includes novel sealing
means including unique weather strips and a sash sealing strip
including means for retaining a window screen constructed integral
therewith. Installation clips and brackets are also provided
whereby the window structure of the invention may be rapidly and
easily installed from either the interior or exterior of a window
opening.
In particular, in the universal window structure of the invention,
the movable sash has been separated from the frame so that the sash
guide rails no longer move in a frame channel and may be termed to
be "floating" in the window frame. Guiding, tilt release and pivot
structure have been constructed to space the sash from the frame
and both the sash and frame have been so contoured as to prevent
metal-to-metal contact and subsequent galling of the window
structure members and noise during operation of the window.
In addition, structure for maintaining the window sash and frame in
structural engagement centrally of the window sash guide rails with
the movable sash closed has been provided whereby the strength of
the window sash guide rails is increased approximately 800 percent
in view of the relative stiffness of the guiding frame rails, which
structure requires no operation other than the normal opening of
the movable sash to disengage the sash from the frame and normal
closing of the movable sash to engage the sash with the frame so
that no special knowledge or instruction is necessary to provide
the added sash guide rail strength.
In addition, inasmuch as the universal window structure of the
invention is intended for use with either guiding frame rails or
the locking frame rail in a lower position, weepage channels and
passages have been constructed in the window structure to permit
weepage with the window installed in each of the intended positions
thereof. The weepage is permitted in accordance with the present
invention while maintaining a superior weather seal, particularly
about the movable sash of the window structure. The weepage is
provided by shrouded openings at the juncture of the guiding frame
rails and the locking frame rail of the frame at both ends of the
locking frame rail formed in conjunction with a combination weather
strip, window screen retaining member extending over the guide
rails of the movable sash and secured to the guiding frame
rails.
Improved glazing structure including a separate retaining member
and stuffer member is also part of the present invention along with
trim structure for finishing the window structure particularly in
dry wall installation of the window structure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in FIG. 1, the universal window structure 10 includes the
frame 12 having a floating sash 14 movably positioned therein and a
fixed glazing panel 16 secured thereto. The sash 14 may be moved
parallel to the frame guide rails 18 and 20 to provide a
single-hung window with the window structure 10 installed with the
orientation illustrated in FIG. 1. The sash 14 may also be pivoted
or tilted about the lock rail thereof to provide a hopper window
when the window structure is installed with the orientation
illustrated in FIG. 1. Installed with guiding frame rails 18 and 20
horizontal to the window structure 10 provides either a left or
right-hand glider window.
Window frame 12 includes the guiding frame rails 18 and 20, the
fixed frame rail 22, locking frame rail 24, and frame check rail
26. Frame adaptor members 28 and 30 are secured to the guiding
frame rails 18 and 20, and in conjunction with the fixed frame rail
22 and frame check rail 26 receive the fixed glazing panel 16. The
frame rails 18, 20, 22, 24, 26, 28 and 30 are all extruded in the
box-like cross sections illustrated of aluminum or the like.
Thus, in contrast to prior universal window frame structures, the
window frame 12 is particularly strong in that it resists torsion
and bending. In addition, due to the box-like cross section of the
frame rails, the window structure 10 presents a particularly simple
and clean appearance in installation whereby the aesthetic
appearance of the window structure 10 is an improvement over prior
universal window structures having a relatively busy appearance due
to the cross section of the window frame extrusions used
therein.
The movable window sash 14 includes a lock rail 32, guide rails 34
and 36, and a tilt rail 38, all extruded in the shapes shown of
aluminum or similar material. As shown best in FIG. 1, the frame
check rail 26 and sash tilt rail 38 are provided with interlocking
projections 40 on the frame check rail 26 and 42 on the sash tilt
rail 38 to effect a particularly tight weather seal therebetween.
In addition, an improved weather strip member 44 as illustrated
particularly in FIG. 32, and which will be considered in more
detail subsequently, is provided between the frame check rail 26
and sash tilt rail 38, as shown in FIG. 1.
The guiding frame rails 18 and 20, fixed rail 22, and locking frame
rail 24 are connected together at the mitered corners of the frame
12 by convenient means such as screws 46. The frame adaptor members
28 and 30 are made from a single piece of extrusion cut into in the
center and subsequently slid on the edge of the guiding frame rails
18 and 20, as shown, prior to connecting of the fixed frame rail 22
and frame check rail 26 to the guiding frame rails 18 and 20, after
which the frame check rail 26 and then the fixed frame rail 22 are
secured to the guiding frame rails 18 and 20 to lock the frame
adaptor members 28 and 30 in position. Thus, close tolerance
cutting of the frame adaptor members and installation of the frame
check rail 26 in an exact position is not necessary with the window
structure 10 illustrated in FIG. 1. This structure is also of
particular advantage in that no fabrication of the guiding frame
rails is required to permit installation of the frame adaptor
members or frame check rail.
In a window structure 10, possible collection of water behind the
weather plane must be considered and provision for weepage of such
water to the exterior of the window structure 10 positioned as
shown in FIG. 1, or with one of the guiding frame rails 18 or 20
positioned horizontally must be provided for. In the window
structure 10 a channel 47 illustrated best in FIG. 20 is provided
between the movable window sash 14 and a composite sealing strip
and screen retaining member 284. Weepage occurs from between the
end of the member 284 and the locking frame rail and the adjacent
surface of the lock rail of the sash in the window structure
10.
With the window structure 10 positioned as shown in FIG. 1, a
weepage opening is provided at each of the corners of the window
structure adjacent the opposite ends of the sash lock rail. With
the window structure 10 positioned as a glider window, a weep
opening is provided at whichever end of the movable sash lock rail
is lower. All of the weep openings so provided are shrouded by the
end of the composite sealing strip and screen retaining member 284
to prevent wind passage through the window structure 10 or driving
of rain through the window structure 10. Thus, the member 284
provides weepage for the window structure 10 in conjunction with
the locking frame rail 24 and such lock rail 32 as well as it
provides a seal for the movable window sash 14 and retains the
screen structure 304, which functions will be considered
subsequently.
As shown best in FIG. 2, a plurality of window structures 10 may be
positioned side by side and mulled by a single window installer
through the use of a mull cover member 48 which receives the edges
of one guiding frame rail 20 and the adjacent guiding frame rail 18
of two separate window structures 10. In installation, the first
window structure 10 is set in place by the installer. The mull
cover extrusion 48, which may be of aluminum or similar material,
is clipped on the guiding frame rail of the installed window
structure 10, followed by the subsequent clipping of the adjacent
guiding frame rail of the second window structure 10 to the mull
cover and the securing of the second window structure 10 in the
window opening. The camming and barb portions 50 and 52 on the mull
cover 48 for receiving the guiding frame rail parts 51 and 53
together with the recesses 54 and 56 for receiving the projections
60 and 62 of the guiding frame rails permit the simple, efficient
installation of the mull cover on the guiding frame rail of the
first window structure and the similarly simple and efficient
connection of the guiding frame rail of the second window structure
to the mull cover 48.
As shown best in FIG. 3, a first modification of the mull cover 48
illustrated in FIG. 2 is executed in plastic and includes the
resilient return portions 64 adjacent each of the recesses 54 and
56 oriented as shown in FIG. 3 whereby the guiding frame rail
projections 60 and 62 are cammed into the recesses 54 and 56 and
are subsequently locked in the recesses by the end 66 of te return
portions 64 extending over the projections 60 and 62 thereof in the
recesses 54 and 56. In all other respects, the modified mull cover
of FIG. 3 has the same cross section as the mull cover 48.
The modification of the mull cover 48 illustrated in FIG. 3A
includes extended camming and barb portions 55 and 57 which diverge
from each other and the portions 59 and 61 which are slanted toward
each other as shown. In installation the modified mull cover
illustrated in FIG. 3A is snapped in place over two adjacent
guiding frame rails 18 and 20 which have previously been secured
adjacent each other n the position illustrated in FIG. 2. The
portions 55 and 57 of the mull cover illustrated in FIG. 3A are
cammed over the portions 51 and 53 of the adjacent guiding frame
rails and the portions 59 and 61 are cammed over the portions 60
and 62 of the guiding frame rails. One man can easily install
mulled windows using the mull cover of FIG. 3A since the mulling of
the windows is accomplished with the windows in place in contrast
to prior procedures wherein windows have been mulled before
installation thereof and a number of men have been required to
install the premulled windows.
The window structure 10 may be glazed in a plurality of different
manners, as shown particularly in FIG. 4, wherein the present
window structure 10 illustrated in FIG. 1, the fixed glazing panel
16 is a single pane of glass held in position by applicant's unique
glazing strip 68 in the inner glazing groove 80. Glazing strip 68
is disclosed in more detail in application Ser. No. 36,303,
referred to above and permits the installation of both single and
double pane glazing panels of different thicknesses in the window
structure 10 with a single glazing strip.
In addition, a storm window including a glazing panel 70 and edge
strip 72 may be installed over the glazing panel 16 by means of
installation clips 74 to provide storm window protection for the
fixed glazing panel of the window structure 10, as shown in more
detail in application Ser. No. 38,453, referred to above.
In contrast, the movable window sash 14 is glazed with thermal
glass 76 having a double thickness with the same glazing strip 68
placed in the outer glazing groove 78 rather than the inner glazing
groove 80. In addition to the two glazing grooves 78 and 80, it
will be understood that due to the shape of the glazing strip 68,
it may be flexed to accommodate single or double-pane glazing
material of different thickness whereby the one glazing strip is
universal for substantially all normal glazing panel
thicknesses.
Again, as shown best in FIG. 4, the frame adaptor extrusions 28 and
30 are provided with a beveled surface 82, while the movable sash
guide rails 34 and 36 are provided with a complementary beveled
surface 84 positioned to be in spaced relation to the beveled
surface 82. Thus, on movement of the movable sash 14, particularly
when the window structure 10 is used as a glider window, no
metal-to-metal contact is present so that galling of the metal
surfaces and noisy operation of the window structure 10 is
eliminated. Care has also been taken in all other areas of the
window construction where movement exists to prevent metal-to-metal
surface engagement and facilitate the overall quiet operation of
the window structure 10.
In addition, the movable portions of the window structure 10 such
as the movable sash 14 are positively spaced from adjacent metal
members such as the frame 12 by, for example, such structure as the
tilt release and guide structure 90 and the sash guide and pivot
structure 92 so that the moveable sash 14 floats in the frame 12.
Thus, overall quiet operation of the window structure 10 is again
facilitated and metal-to-metal surface engagement and therefore
galling of the members of the window structure 10 is prevented.
The movable sash guide rails 34 and 36, tilt rail 38 and lock rail
32 are secured together by convenient means such as screws 86 and
88 which are also used to install the sash guide and tilt release
structure 90 and the sash guide and pivot structure 92,
respectively.
False window mullion structure 96 including false window mullion
members 98, connecting members 100, and installation brackets
therefor 102, as disclosed in more detail in application Ser. No.
7,452, referenced above, may be provided in conjunction with the
window structure 10 and are shown in FIG. 1. Window structure 10
also includes the known sash balance structure 104 adapted to be
secured within the pocket 106 in guiding frame rail 20 by means of
screw 108 or the like.
A hopper lock 110 again as considered in more detail in application
Ser. No. 36,303, referenced above, may be used in conjunction with
the window structure 10, and is shown in FIG. 1. The hopper lock
110 is engaged at end 112 in pocket 114 in sash guide rail 36 and
is engaged at end 114 in pocket 106 of guiding frame rail 20 in the
window structure 10 and limits pivotal movement of the movable sash
14 about the lock rail thereof in accordance with the position of
the hopper lock 110 in the guiding frame rail 20 and the position
of the movable sash 14 when it is tilted.
In more detail, the improved sash guide and tilt release structure
90, as best shown in FIGS. 5-7, includes a separate sash guide
member 118, a separate tilt release member 120 and biasing spring
122. As shown best in FIGS. 5 and 6, the sash guide member 118 is
secured in the pocket 114 in the sash guide rail 36 by means of the
assembly screw 86 for the movable sash 14.
In assembly, the spaced apart flanges 124 space the sash guide rail
36 from the guiding frame rail 20. The flanges 124 on the sash
guide member 118 are beveled at 126 as a continuation of bevel 84
on guide rail 36 to provide clearance between the sash guide member
118 and the frame adaptor members 28 and 30 on opposite sides of
the frame 12 with the member 118 used on either side of the frame
12. The flanges 124 are provided with a further bevel 128 to
provide clearance for the sash balance 104 in assembly. The flanges
124 further include the hook-like ends 130 thereon which define a
pivot notch 132 into which the tilt release member 120 of the sash
guide and tilt release structure is positioned in assembly, as will
be best seen in FIG. 6.
The head portion 136 of the sash guide member 118 fits within the
slot 138 in the tilt release member to guide the tilt release
member on pivoting thereof about the pivot portion 134 thereof.
Head portion 136 has the camming abutment 140 thereon which permits
camming of the head portion into the slot 138 and which abuts the
handle portion 142 of the tilt release member 120 in assembly to
prevent disassembly of the sash guide and tilt release structure 90
except on upward bending of the handle 142.
The tilt release member 120 as shown best in FIG. 7 includes the
handle portion 142 having the slot 138 therein for receiving and
guiding the head 136 of the sash guide member 118, which slot is
maintained in relatively close tolerance by-means of a spacing
strap 144 placed across the open end thereof above the opening 146
in the tilt release member 120 through which the head of the screw
86 extends for ease in assembly. The tilt release member 120
further includes the flanges 148 thereon extending beyond the end
150 of the handle 142 so that in assembly the flanges 148 extend
within the pocket 106 in a frame jamb member to prevent tilting of
the movable sash 14 except on pivoting of the tilt release member
120 about pivot portion 134 thereof to compress spring 122 and
remove flanges 148 from the pocket 106. The end 150 of the handle
142 abuts the edges of the pocket 106 in jamb 20 to prevent entry
of the handle 142 into the pocket 106 and thus limits entry of the
flanges 148 into the pocket 106 in assembly so that contact of
flanges 148 with the sash balance 104 on movement of the sash 14 is
prevented.
The recess 152 is provided in the tilt release member 120 and in
conjunction with a similar recess in the sash guide 118 locates the
ends of the spring 122 between the sash guide member 118 and the
tilt release member 120 in assembly. The toe portion 154 of the
tilt release member 120 is adapted to steady the member 120 on
vertical movement of the movable sash 14, while the heel portion
156 of the tilt release member 120 engages the guide rail of the
sash 14 within the pocket 114 to limit the pivotal movement of the
member 120 under bias of the spring 122 in assembly.
In use the sash guide and tilt release structure 90 is first
assembled by placing the pivot portion 134 of the tilt release
member 120 in the notch 132 and positioning one end of the spring
122 in the recess 152 with the other end of the spring 122 in a
guide therefor in the sash guide member 118. The spring is then
compressed by pivoting the tilt release member 120 about the pivot
portion 134 thereof to cam the head 136 of the sash guide member
118 into the slot 138 in the tilt release member 120. So assembled,
the sash guide and tilt release structure 90 is secured in the sash
guide rail pocket 114 at the tilt rail of the movable sash 14 by
means of the screw 86.
The handle 142 of the tilt release member 120 is then moved toward
the sash guide member 118 to compress the spring 122 and the
movable sash 14 which has been in a tilted position in the frame 12
is tilted into the plane of the frame 12 of the window structure
12. The tilt release member 120 is then released so that the spring
122 moves the flanges 148 into the pocket 106 in the guiding frame
rail 20 as shown in FIGS. 5 and 6 and the end 150 of the handle 142
abuts the guiding frame rail 20 at the entrance to the pocket 106
to limit insertion of the tilt release member 120 into the pocket
106 under bias of the spring 122. The movement of the sash 14 in
the frame 12 is then guided by the flanges 148 on the tilt release
member 120, and the sash 14 and frame 12 are spaced by the flanges
124 on the sash guide member 118. When it is desired to again tilt
the movable sash 14 into the hopper position, the handle 142 is
grasped and moved toward the movable sash 14 to remove the guide
flanges 148 from the pocket 106 of the guiding frame rail, and the
movable sash 14 may be tilted.
In the above consideration of the sash guide and tilt release
structure 90, it will be understood that one such structure may be
provided at each end of the tilt rail of the movable sash 14.
The movable sash 14 is also guided by the sash guide and pivot
structure 92 as indicated above, which is shown best in FIGS. 8-11.
As shown in FIG. 11, the sash guide and pivot structure 92 includes
the sash guide and pivot member 160 and the spring 162.
The sash guide and pivot member 160 includes the pivot portion 164
which as shown is beveled at the outer end thereof for insertion in
the pocket 106 in the guiding frame rail 20. Pivot portion 164
provides a pivot axis at the ends of the lock rail of the movable
window sash 14 for tilting the sash 14 into a hopper position. The
sash guide and pivot member 160 further includes the rectangular
portion 166 separated from the pivot portion 164 by the flange 168,
which flange also extends beneath the rectangular portion 166
thereof as shown in FIG. 11.
In assembly, the rectangular portion 166 is positioned within the
pocket 114 in the lock rail 36 of the movable sash 14 with the
flange 168 extending over the exterior edge of the lock rail and
over the end of the lock rail to provide a finished corner of the
movable sash 14 so that the sealing strip for the movable sash 14
will not be damaged on movement of the movable sash as, for
example, into and out of a tilted position. The sash guide and
pivot member is secured to the end of the sash guide rail 36 and to
the lock rail 32 by means of the screw 88 illustrated in FIG. 1
extending through the opening 170 in the sash guide and pivot
member.
The sash guide and pivot member 160 further includes the extension
172 having the spring guide 174 thereon and which includes a
portion 176 on one side of the end thereof and a barb portion 178
on the other side of the end thereof. The end of the extension 172
is further provided with beveled surfaces 180 and 182 at both sides
of the barb and is provided with feather edges 184 and 186 as shown
best in FIG. 11, all of which facilitate pivotal movement of sash
14 into and out of the plane of the window structure 10.
In assembly the sash guide and pivot member 92 with spring 162 on
guide 174 is secured to an end of the sash guide rails at an end of
the lock rail as shown in FIG. 9 by means of a screw extending
through opening 170. The guide portion 176 assumes a normal
operating position within the pocket 114 of the sash guide rail 36
of the sash 14 on installation. On pivoting of the sash 14 into the
plane of the window frame 12 from the tilted position thereof in
which the pivot portions 164 of member 160 are inserted in pockets
106, the extension 172 is cammed into the desired position thereof
by cam surface 180 on the extension 172. In the plane of frame 12,
the extension 172 is prevented from entering the recess 106 in the
guiding frame rail 20 and is guided into movement into and out of
the plane of the frame 12 not only by the beveled edge 180 but by
the beveled edge 182 and the feathered edges 186 and 184 as
indicated above.
The sash guide and pivot member 160 is useable without the sash
balance shoe 188 in a glider window installation or on a
nonbalanced side of a single-hung window installation with the
spring 162 removed. Removal of spring 162 deactivates portion 172
of member 160.
In addition, it will be understood that the extension 172 of member
160 could be a separate member pivoted to the pivot portion and
rectangular portion separated by the flange 168 as for example in
the sash guide and tilt release structure 90.
The barb 178 on extension 172 is operable in conjunction with the
sash balance shoe 188 illustrated best in FIG. 10 to secure the
sash balance 104 which is in the pocket 106 to the movable sash 14
through the sash guide and pivot member 160.
The sash balance shoe 188 as best shown in FIGS. 9 and 10 includes
the recess 190 in the rear thereof and the recess 192 in the front
thereof, which recesses are connected by a transverse slot 194
extending therebetween. Thus, the end of the torsion ribbon 196 of
the sash balance 104 is readily secured to and released from the
sash balance shoe 188 on moving the end thereof which includes the
offset portion 198 through the slot 194, all as considered in more
detail in application Ser. No. 36,303 referenced above.
The sash balance shoe includes the surfaces 200 and 202 thereon
shown best in FIG. 10 which are engageable with the internal
surface of the pocket 106 at one side of the entrance thereof and
with the external surface at the entrance of the pocket 106 on the
other side thereof as shown best in FIG. 8 in assembly. The
surfaces 200 and 202 locate the sash balance shoe in the pocket 106
when it is connected to the torsion ribbon 196. Torsion ribbon 196
is constructed to provide only counterclockwise torsion on the sash
balance shoe 188 as illustrated in FIG. 8. Torsioning of the sash
balance in the wrong direction is thus not possible with the sash
balance show 188, since it would not be possible to install the
sash balance shoe 188 in the recess 106 if the sash balance shoe
were torsioned in the wrong direction.
The bevel surface 204 on one side of the sash balance shoe provides
clearance for assembly screws. The arcuate surface 206 on the other
side of the sash balance shoe 188 permits easy rotating of the sash
balance shoe 188 installed on the torsion ribbon 196 into the
pocket 106 in the guiding frame rail 20 and removal thereof from
the pocket 106.
In operation, with the sash balance shoe attached to the sash
balance 104 within the pocket 106, the sash balance shoe 188 will
be moved to the upper limit thereof allowed by the sash balance
104. The movable sash 14 may then be inserted in the window opening
therefor between the guiding frame rails 18 and 20 with the pivot
portions of the sash guide and pivot member 160 in the pockets 106
which will require canting of the lock rail of the movable window
member 14 from a position wherein the movable window is in a
substantially horizontal plane to a position in which the movable
window slants toward one guiding frame rail or the other and
subsequent movement of the movable window into a horizontal plane
after the pivot portions 164 of the sash guide and pivot members
160 at each side thereof have been positioned in the respective
pockets 106 in the guiding frame rails 18 and 20.
The movable window 14 is then pivoted into a closed position with
the extension 172 of the sash guide and pivot member 160 being
cammed past the guiding frame rails 18 and 20 to place the movable
window sash 14 in the plane of the frame 12 position. The movable
window sash is then moved toward the fixed frame rail as far as
possible at which time the lower beveled edge 208 on the sash
balance shoe 188 will cam past the barb 178 on the extension 172,
and the barb 172 will snap over the upper edge 210 of the sash
balance shoe 188. Subsequently, when the movable sash 14 is moved
toward the locking frame rail, the sash balance shoe 188 will be
secured to the sash guide and pivot member 160 for movement
therewith to provide a counterbalance for the movable window sash
14 in use as a single-hung window.
On subsequent pivoting of the movable window sash 14 past
approximately 30.degree., the sash balance shoe member 188 is
released by the barb 178 on the extension 172 of the sash guide and
pivot structure and will return toward the fixed frame rail to a
limiting position thereof to be reengaged on subsequent tilting of
the sash back into the plane of frame 12 and movement toward the
fixed frame rail. The sash balance shoe 188 is not released on
tilting of the movable sash 14 less than approximately 30.degree.
to permit ventilation. With such operation, it will be readily seen
that it is not necessary with the sash guide and pivot structure
and the particular sash balance shoe associated therewith disclosed
herein to exactly locate the pivot portions 164 of the sash guide
and pivot member on installation of the movable sash 14 after it
has been removed to insure engagement of a sash balance shoe which
has been maintained in the position it held on removal of the
movable window sash.
The modified sash guide and pivot member 212 illustrated in FIG. 12
is intended for use by itself without a sash balance or with either
of the sash balance shoes 214 and 216 illustrated in FIGS. 13 and
14.
The sash guide and pivot member 212 includes the pivot portion 218
and a rectangular portion 220 separated by the flange 222 which as
shown extends around the bottom of the rectangular portion 220. As
with the sash guide and pivot member 160 illustrated in FIGS. 8-11,
the sash guide and pivot member 212 is secured to the end of a
movable sash guide rail at the end of the sash lock rail in the
pocket 114 by an assembly screw extending through the opening
224.
Also as before, the pivot portion 218 is slightly larger in the
direction of movement of the movable sash 14 in the plane of the
frame 10 than it is transverse to the plane of the frame 10 with
the movable sash 14 in a non-tilted position and the sash guide and
pivot member 212 installed thereon whereby on pivoting of the sash
14 out of the plane of the window frame into the hopper position,
the bottom edge of the movable sash 14 is locked in a predetermined
position in the frame 12 by wedging the pivot portion 218 between
the opposite surfaces at the opening of the pocket 106.
The sash balance shoe 214 is similar to the sash balance shoe 188
in the upper portion 226 as shown. However, an extension 228 is
provided on the bottom thereof which includes an elongated opening
230 therethrough for receiving the pivot portion 218 of the sash
guide and pivot member 212. Thus, with the sash guide and pivot
member 212 used in conjunction with the sash balance shoe 214, the
pivot portion 218 must be exactly located on reinstalling a removed
movable window sash 14 to position the pivot portion 218 in the
opening 230.
Similarly, the sash balance shoe 216 may be used with the sash
guide and pivot member 212, and again receives the offset end 198
of the sash balance ribbon 196 in the same manner as the sash
balance shoes 188 and 214, as particularly shown in FIG. 9.
However, in place of the opening 230 in the lower extension 228
shown on the sash balance shoe 214, the opening 234 in the sash
balance shoe 216 is open at the lower end and has hook portions 236
at the open end thereof with arcuate lower camming surfaces 238.
Thus, with the sash balance shoe 216 a sash 14 may be replaced in
the window frame 12 in any position along the guiding frame rails
and when moved toward the fixed frame rail will spread the lower
portion of the sash balance shoe 216 apart with the pivot portion
218 of the sash guide and pivot member 212 whereby the pivot
portion 218 is received in the opening 234 and the sash balance
shoe 216 is locked to the movable window sash 14 until such time as
the movable window sash 14 is again removed from the frame 12.
With the movable sash 14 in the position in the window structure 10
shown in FIG. 1, the lock rail of the movable window sash 14 is
automatically locked to the locking frame rail 24 of the window
frame 12 by the lock structure 240. Lock structure 240 includes the
lock body member 242 and the lock actuating member 244 together
with the lock spring 246, illustrated best in FIG. 17.
Lock body member 242 includes an end elevation and transverse cross
section which allows it to be slidably received in the
longitudinally extending recess 248 in the lock rail 32 of the
movable sash 14, as shown best in FIG. 16. In addition, the lock
body member 242 includes the slot 250 therein for receiving a
locking frame rail cross section part 252 having the barb 254
thereon with the movable sash 14 in a fully closed position. Slot
250 serves to align the lock structure 240 with the locking frame
rail 24 of the window frame 12.
An opening 256 is provided through the lock body member 242 to
receive the lock actuating member 244 and is provided with recesses
258 in the opposite ends thereof for receiving the pivot portions
260 of the lock actuating member 244. The lock body member 242 is
further provided with a cylindrical portion 262 including a recess
268 therein for receiving the spring 246 in assembly.
The lock actuating member 244 includes the locking part 263 having
barb 264 thereon engageable with the locking barb 254 on the
locking frame rail extension 252 in operation to lock the movable
window sash 14 in a closed position. Lock actuating member 244 is
further provided with a centrally located projection 266, shown
best in FIG. 16, adapted to extend within the recess 268 in the
cylinder 262 beneath the spring 246 in assembly. The handle portion
270 on the lock actuating member 244 is movable to pivot the lock
actuating member 244 about the pivot means 260 thereof in
opposition to the bias of the spring 246 which is in engagement at
the opposite ends thereof with projection 266 of the member 244 and
the top of the pocket 248 in the sash lock rail 32 in assembly to
pivot the locking barb 246 out of engagement with the locking barb
254 on the locking frame rail extension 252 and permit movement of
the window sash 14 as desired. The lock structure is automatically
reengaged on closing of the movable window sash 14 fully to cam the
locking barb 214 over the locking barb 254.
It will be particularly noted that the locking structure 240
permits movement of the locking structure 240 anywhere within the
recess 248 in the sash lock rail 32 so that with the window in use
as a glider window, the lock structure 240 may be lowered for use
by shorter people or may be raised to prevent use thereof by
children, as desired.
Even with the sash guide and tilt release structure 90 and the sash
guide and pivot structure 92 engaged with the frame jambs 18 and 20
and with the lock structure 240 secured, during very high winds the
movable sash guide rails 34 and 36 which are not inserted in the
usual guide channels to permit tilting of the sash may bend
sufficiently to break the seal between the guiding frame rails and
movable sash guide rails without additional support of the sash
guide rails by guiding the frame rails. Accordingly, the bracket
structure 272 may be provided in conjunction with sash having a
large vertical dimension in areas where extremely high winds may
occasionally be expected.
The bracket structure 272 includes brackets 274 and 276 secured at
right angles to each other on, for example, the sash guide rail 36
and the guiding frame rail 20 by means of screws or the like (not
shown). The brackets which are identical include the rectangular
spacing portion 278 having the screw opening 282 extending
therethrough and the locking portion 280 as shown in the
perspective view of the bracket 276 illustrated in FIG. 19.
With a pair of brackets 274 and 276 installed at both sides of the
movable window sash 14, as shown in FIG. 18, the sash guide rails
34 and 36 are locked to the guiding frame rails 18 and 20 until the
movable sash 14 is raised approximately a half inch to remove the
locking portion of the bracket 274 on the sash guide rail 36 from
the pocket formed by the locking portion of the bracket 276 in
conjunction with the guiding frame rail 20. No special knowledge or
instructions are necessary to permit operation of bracket structure
272.
The bracket structure 272 provides the additional support of the
guiding frame rails 18 and 20 which are comparatively very strong
to the sash guide rails 34 and 36, with the movable jamb 14 in a
locked position. By placing the brackets 274 and 276, which are
very inexpensive, in the center of the sash guide rails an increase
in sash guide rail strength of 800 percent is possible.
A seal is provided between the sash guide rails 34 and 36 of the
movable sash 14 and the guiding frame rails 18 and 20 by the
composite sealing strip and screen retaining member 284 shown in
installation on the guiding frame rail 20 and in conjunction with
the sash guide rail 36 in FIG. 20. As shown, the composite sealing
strip and screen retaining member 284 includes a relatively rigid
L-shaped cross section portion 290 having hook parts 292 and 294 on
one leg thereof which engage the grooves 296 and 298 extending
longitudinally in the guiding frame rail 20 and the camming part
300 and locking lip 302 for retaining the screen structure 304 on
the other leg thereof. A relatively soft sealing strip portion 306
is extruded simultaneously with the L-shaped portion 290 of the
composite member and is adapted to extend over the sash guide rails
36 with the composite member 290 secured to the guiding frame rail
20 as shown in FIG. 20 to provide a seal therebetween which is
increased by wind pressure on the exterior of the window structure
10 until the sash guide rails 34 and 36 deflect sufficiently to
require the bracket structure 272. The composite sealing strip and
screen retaining member 284 thus eliminates the need for separate
screen retaining clips.
In installation, the composite sealing strip and screen retaining
member 284, as shown in perspective in FIG. 21, is snapped onto a
guiding frame rail such as rail 20 and extends substantially the
entire length of the movable sash 14 in a closed position over the
guide rail 36 thereof as shown in FIG. 20. Screen structure 304 is
then inserted behind the retaining lip 308 on the frame check rail
38 as shown best in FIG. 1, and the screen is cammed into the
screen retaining portion of the L-shaped portion of the composite
member 284 over the camming part 300 until it snaps behind the
locking lip 302, after which the screen is lowered to be received
behind the screen retaining lip 310 illustrated in FIG. 1 on the
locking frame rail 24.
The composite sealing strip and screen retaining member 284
provides a superior bug seal. Thus, even though a screen frame
member may be bowed, the L-shaped portion 290 of the member 284
prevents bugs from getting between the window frame 12 and screen
structure 304 with the screen structure behind the locking lip 302.
In addition, the L-shaped portion 290 of the member 284 provides a
wind screen so that wind does not get behind the screens and build
up pressure which has in the past resulted in screens popping out
of window structures of, for example, moving mobile homes.
Window structure 10 may be installed in a window opening 312 from
the inside thereof by use of installation clips 314, illustrated
best in FIG. 24. Installation clip 314 includes the U-shaped
portion 316 having the connecting part 318 and the leg parts 320
and 322. A spacing portion 324 is provided extending from the
connecting portion 316 of the clip 314, as shown in FIG. 24. The
nailing strip 326 and the resilient retaining portion 328 having
the retaining lip 330 thereon are connected to an extension 332 of
the connecting portion 316 of the cross section of the clip 314,
all as shown best in FIG. 24.
Installation clips 314 are installed in the guiding frame rails 18
and 20, fixed frame rail 22 and locking frame rail 24, as shown for
example in FIG. 22, by inserting the leg portions 320 and 322
thereof in the pocket 334 in, for example, the locking frame rail
24 illustrated in FIG. 22 until the locking lip 320 cams over the
portion 336 of the rail 24. The window structure 10 with the
installation clips 314 assembled therewith is then positioned in
the window opening 312 until the spacing portion 324 abuts the wood
buck 338 defining the window opening 312, and the clips 314 are
nailed to the wood buck 338 by driving a nail through the nailing
strip 326 of the clip 314 which may be accomplished from the inside
of the window opening 312. The window opening 312 may then be
finished by securing the trim members 340 around the opening 312 as
shown and as more fully described in application Ser. No. 36,303,
referenced above.
If it is subsequently desired to remove the window structure 10
from the window opening 312, removal may be accomplished by first
depressing the resilient retaining portion 328 of the installation
clips 314 by means of a screwdriver positioned on the end thereof
to provide clearance between the retaining lip 330 and the locking
frame rail 24 and similar members having installation clips 314
secured thereto. Window structures 10 may then be reinstalled by
merely moving them into the opening again over the installed clips
to place the leg portions of the clips in pockets 334 and to move
the locking lip 330 over the part 336 of the frame rail.
Installation of and removal and replacing of window structures 10
in multistoried construction is thus greatly facilitated, since all
such work may be accomplished from inside the building
structure.
Wherein it is desired to use wood trim members 342, the nailing
portions 326 of the installation clips 314 may be deformed prior to
or at the time of nailing thereof to bucks 338 about the opening
312 to permit the placing of the wood trim members 342 over the top
thereof and between the nailing portion 326 and the retaining
portion 328 of the installation clips 314 as illustrated in FIG.
23.
In an alternate construction illustrated in FIG. 25, clips 315
include the U-shaped portion 317 having a generally V-shaped
connection part 319 to permit easy insertion of the clip 315 within
the pocket 334 in for example the frame rail 24. The spacing part
321 is secured to the leg 323 of the U-shaped portion 317 by means
of an offsetting part 325. The nailing strip 327 and resilient
retaining portion 329 are secured to an offsetting portion 331
extending from the end of the other leg 333 of the U-shaped portion
317 of the clip 315.
The installation and use of the clip 315 is substantially the same
as the installation and use of the clip 314. The V-shaped
connecting part 319 of the U-shaped portion 317 of the clip permits
easy insertion of the clip into the pocket 334. Also the clip 315
has been made nonreleasable once it is inserted in a window frame
so that the resilient portion 329 of the clip 315 is terminated at
the lip 335 whereby an installation there will be no part of the
retaining portion 329 extending beyond the part 336 of frame rail
24 in installation so that depression of the resilient portion once
the clip 315 is installed is difficult or impossible. The clips 314
can of course be provided with the resilient portion 328 terminated
at the lip 330 if it is not desired to separate the clips from the
window frame.
In a further alternate construction as illustrated in FIG. 25, an
installation clip 343 constructed from sheet metal is used to
install the window structure 10 in a window opening 344 from the
inside of the window opening. As shown in FIG. 26, the clip 343
includes the leg portions 346 offset at 348 and again at 350 to
provide integral nailing portions 354 for securing the clips 343 to
the wood buck 352. The leg portions 346 are connected by the
connecting portion 356. The resilient locking portion 358 of the
installation clip 343, as shown, is a portion cut out of the sheet
metal clip between the leg portions thereof which is connected
thereto at the connecting portion of the clip 356 which locking
portion 358 is inclined with respect to the leg portions of the
bracket and is provided with an offset central portion 360 and an
L-shaped terminal portion 362. Alternatively, nailing openings may
be provided in flat ends of the leg portions 346 of the clip 343 in
place of the integral nailing portions 354 and offsets 350.
As shown in FIG. 25, clips 343 are installed on wood buck 352, for
example. The window structure 10 is then inserted in the window
opening 344 and the clips 343 are placed in the pockets 344, after
which suitable trim 364 is applied around the interior of the
window opening 344. This is in contrast to clips 314 which are
placed in pockets 344 and are subsequently nailed to the wood buck.
Again, if it is desired to remove the window structure 10, the
clips may be compressed by means of a screwdriver placed on the
part 366 of the L-shaped terminal portion 362 of the central
portion 360 of the clips.
The modified installation clip 368 illustrated in FIG. 27 is
substantially the same in operation as the clip 343 but is formed
of spring wire including integral nailing portions 370 on the ends
thereof and an L-shaped locking portion 372. The use of the clip
368 and the position thereof in assembly is substantially the same
as the use of the clip 343 and the position of the clip 343 in
assembly.
As shown best in FIGS. 28 and 29, the window structure 10 as
illustrated by the frame sill member 24 may also be installed from
the exterior of different window openings 374 and 376 in
conjunction with the installation bracket 378 illustrated best in
FIG. 30. As shown, the installation bracket 378 has a T-shaped
cross section with a screw runner channel 380 extending the length
thereof at the intersection of the stem and crossbar of the
T-shaped cross section. Bracket 378 has notches 382 and 384 at the
ends thereof constructed to provide room for sealing strips 384 on
the part 386 of the cross section of jamb 24, as shown best in FIG.
31. Notches 382 and 384 are desirable but not essential.
In installation of a window structure 10 from the exterior of the
window opening 374 in conjunction with the installation brackets
378, the brackets are inserted in the pockets 334 at required
positions around the window frame 12. The screws 390 are passed
through prepared openings in the window frame 12 and through the
screw runners 380. The window structure 10 is then positioned in
the window opening 374 and the screws 390 are driven into the wood
bucks 392 defining the window opening 374. Subsequently the
extruded plastic trim members 374 are placed in position in the
window opening 374 from the interior thereof. When it is desired to
remove the window structure 10 from the opening 374, it is merely
necessary to remove the screws 390 and subsequently remove the
window structure 10.
The installation of the window structure 10 illustrated in FIG. 29
illustrates the versatility of the installation bracket 378 with
different building structures and is shown in conjunction with an
elongated plastic trim member 410 for use in providing an
installed, trimmed window in solid masonry construction.
As shown best in FIG. 31, the weather seal 384 includes a generally
H-shaped cross section having a crossbar 396 and the shorter
sealing leg 398 and the longer sealing leg 400 which engage the
surface of the building construction surrounding the window opening
374, as shown in FIG. 29. The sealing strip 384 further includes
the leg 402 extending along the bottom of the part 386 of the
window frame sill 24 and the leg 404 having the locking rib 406
thereon which extends into a recess 408 extending longitudinally in
the part 386 of the locking frame rail 24 to secure the sealing
strip 396 to the rail. The sealing strips 384 have been found to
provide a more reliable and less messy weather strip which is easy
to install in conjunction with the window frame 12 than the usual
caulking.
The modified weather seal 385 illustrated in FIG. 32 is exactly the
same as weather seal 384 with the exception of the leg 387 which in
the modified weather seal 385 has a portion 389 extending parallel
to and away from the crossbar 391 and has a returned portion 393
shaped as shown in FIG. 32. The portion 389 provides more
flexibility in the leg 387 and the returned portion 393 permits
movement of the window frame in the direction of extent of portion
389 of leg 387 without damage to the seal provided by strip
385.
In the further modified weather seal 395 illustrated in section in
FIG. 34, the crossbar 397 and the legs 399 and 401 of the generally
H-shaped cross section are the same as the corresponding portions
of the weather seals 384 and 385. The leg portions 403 and 405 are,
however, thinner than the leg portions 398 and 400 of the weather
seal 384 and are more arcuate than the leg portion 387 of the
weather seal 385. Thus, in installation the legs 403 and 405 may be
more readily flexed to provide a continuous weather seal and the
window may be moved in the direction of extent of either leg 403 or
405 from the crossbar 397 without breaking the weather seal due to
deforming the legs 403 or 405.
The sealing strip 44 between the sash lock rail 32 and the locking
frame rail 24, as shown best in FIG. 33, has a generally Y-shaped
cross section including a shorter, thicker leg 412 which is more
resistant to bending than the longer, thinner leg 414. This
configuration for the sealing strip 44 permits ready installation
of the sealing strip in the dovetail recess 416, inhibits removal
of the strip in the recess in operation and facilitates deforming
of the sealing portion 418 of the Y-shaped cross section 44 to
provide a seal in operation. Such sealing members have been found
to be easier to install by rotating the sealing members into
position in the recesses 416 on flexing of the thinner leg 414 and
to be more efficient particularly between the sash lock rail 32 and
locking frame rail 24 and at the frame check rail 26 and sash tilt
rail 38 than the usual felt weather stripping at these points.
The improved window glazing structure 440 illustrated in assembly
in FIG. 36 comprises a retaining member 442 and a stuffer member
444. As shown, the retaining member 442 is an elongated strip with
an L-shaped cross section having a foot portion 446 which is
adapted to fit within the recesses 78 or 80 in the window sash
guide rail 36. The stem portion 448 of the retaining member 442
which is connected at an angle slightly greater than 90.degree. to
the foot portion 446, as illustrated, is terminated in the portion
450 extending substantially perpendicular to the window pane 76.
The stuffer member is also an elongated strip provided with a cross
section as shown in FIG. 36 and includes the recess 452 into which
the terminal portion 450 of the retaining member 442 extends in
assembly and barbs 454 and 456 engaged with the window pane 76 in
assembly.
With the structure 440, when it is desired to glaze a window sash
14, the window pane 76 or other closure panel is positioned as
shown in FIG. 36. The retaining member 442 is positioned with the
foot portion 446 thereof in the recess 480 and the stuffer member
444 is then wedged between the retaining member 442 and the window
pane 76 with the barbs 454 and 456 in sealing engagement with the
window pane 76 until the end 450 of the retaining member 442 snaps
within the recess 452 in the stuffer member 444. A tight glazing
seal may thus be provided extending completely around the window
pane 76.
The stuffer member 444 is used in conjunction with a second similar
stuffer member 458 illustrated in section in FIG. 37 with a single
retaining member 442 to glaze window rails such as sash rail 14
with glass panes or panels having different thicknesses. The
stuffer member 458 is similar to the stuffer member 444 but
includes the elongated barbs 460 and 462 thereon. Barb 462 extends
from the end 464 of the stuffer member 458 rather than the center
thereof as in the case of stuffer member 444. Thus, the stuffer
member 458 will be used to glaze panels of lesser thickness, while
the stuffer members 444 will be used to glaze panels of relative
greater thickness with the retaining member 442 in either of the
panels 78 and 80. Since both of the stuffer members 444 and 458 may
be used to glaze a plurality of sizes of panels in themselves due
to the flexibility of the retaining member 442 and the barbs 454,
456, 460 and 462, the entire range of normal glazing panels may be
glazed with the three members 442, 444 and 458, which are
particularly simple to install and which are capable of being
removed on stripping of the stuffer members from the retaining
member 442, if desired.
The trim member 468 shown in section in FIG. 38 is an elongated
L-shaped strip having a foot part 470 terminated at one end in a
portion 472 extending in the same direction as the stem part 474 of
the L-shaped strip. As shown, the strip 468 is adapted to receive
an edge of the dry wall structure 466 in assembly and is spaced
therefrom by the terminal portion 472. An extension 476 of the foot
part 468 engages one end of the lip portion 471, extending around
frame 12. An open returned portion 478 depends from the end of the
stem part 474 of the strip 468 to close the joint between the strip
468 on the portion 471 of the frame 12.
When the window structure 10 is installed in conjunction with dry
wall material 466, as shown in FIG. 38, a trim member 468 is
provided to extend over the frame portion 470 to finish the edge of
the dry wall material. As shown, in installing the window frame 10
illustrated by the guiding frame rail 18 in FIG. 38 in a window
opening 472 defined by wood studs 474, the window frame 12 is
positioned in the window opening in the usual manner, the trim
member 468 is applied to the portion 470 of the guiding frame rail
18 and the dry wall material 466 is subsequently positioned as
shown in FIG. 38 to complete a trimmed window installation.
The modified trim member 482 illustrated in FIG. 39 has a cross
section exactly the same as the cross section of the trim member
468 and in addition the cross section of the trim member 482
includes the second L-shaped portion 484 having the stem part 486
which is a continuation of the stem part 474 of the L-shaped trim
member 468 and the foot part 488 extending at an angle of less than
90.degree. to the part 486, as shown in FIG. 39. The part 488 of
the trim member 482 is adapted to fit between the dry wall
structure 466 and the wall stud 474 so that in assembly the
terminal portion 472 is biased into engagement with the dry wall
structure trimmed thereby which has a thickness such that in
assembly the foot part 488 of the second L-shaped portion 484 of
the trim member 482 is forced into a substantially perpendicular
position with respect to the stem part 486 of the portion 484. The
installation of the trim member 482 on the window structure 10 is
the same as the installation of the trim member 468.
In the further modified trim member 490 illustrated in FIG. 40, the
extension 476 included on trim members 468 and 482 is removed from
the first L-shaped portion 492 of the trim member 490 and extension
494 is placed thereon to space the trim member 490 from the end of
the dry wall structure 466 in assembly in the same manner as the
terminal portion 472 spaces the trim member 468 from the dry wall
structure 466. The open returned portion 496 of the trim member 490
which forms recess 502 further has secured to the end thereof the
L-shaped portion 498, the foot part 500 of which is again adapted
to fit between the dry wall structure 466 and the stud 474 in
assembly. Thus, with the edge of the frame lip 471 in the recess
502 in the trim member 490 in installation, the L-shaped portion
492 is urged into engagement with the window frame to provide a
tight joint therebetween and the snap-in installation of the window
frame 12. The aesthetic installation of the window frame 12 within
the dry wall member 466 is thus facilitated.
While one embodiment of the present invention has been considered
in detail, it will be understood that other embodiments and
modifications are contemplated by the inventor. It is the intention
to include all modifications and embodiments in the disclosure as
are defined by the appended claims within the scope of the
invention.
