Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to tilting double hung windows and refers
more specifically to a tilting double hung window having a single
plastic guide member between the window sash and window frame at
each side thereof for providing compression, weatherstripping, and
sash guiding functions, a two-part camming and locking structure
for pivotally mounting the sash with respect to the guide member
and window frame, unique glazing and mullion structure and packing
clip structure for maintaining the window frame dimensions during
shipment and installation.
2. Description of the Prior Art
In the past tilting double hung windows of the type which may be
cleaned from the inside of a building in which the window is
installed by pivoting the window sash about one edge thereof to
expose the outside surface for cleaning have been deficient in that
the usual means for supporting the sash in the window frames have
been rather complicated, often expensive, and sometimes
inefficient. Thus, a minimum of three separate members, that is a
metal guide for the sash, spring means operable between the window
guide and metal frame for maintaining compression of the metal
guide against the sash, and a felt member or similar weatherstrip
material between the sash and outer frame have usually been
required at each side of the window sash.
Wherein locking structure has been provided in the past to maintain
the sash of tilting double hung windows in a predetermined vertical
position when tilted, the locking structure has been complicated,
expensive to manufacture or inefficient. Further, the prior locking
structures have not generally been readily engageable with and
releasable from assembly with counterbalance structure for the
sash.
Similarly, in the past, window sash have sometimes not been capable
of being reglazed readily and where glazing has been possible,
reglazing of a window sash has required considerable skill and
special tools and material. Sealing between two adjacent windows
has also been rather haphazard in the past, often amounting to
merely packing calking material between the adjacent windows and
providing flanges or the like to hide the calking material.
Again, in prior window structures wherein a sash is placed in a
frame for shipment to and installing on a job site, the frames
often become bowed or warped out of shape in storage, shipment or
in installing, so that the finished window in place has in the past
often been difficult to operate due to irregularities in the frame.
Correction of the irregularities on the job site again requires
considerable skill and is time consuming and therefore
expensive.
In addition, prior window structures have generally been either
metal or wood, that is, if a metal exterior has been required in
the past for maintenance purposes, the interior of previous window
structures has generally also been metal. Conversely, when a wooden
window has been desired for aesthetic appearance and warmth, the
entire window has usually been constructed of wood in the past. The
interior aesthetic appearance and warmth of wood window structure
has not previously been satisfactorily, combined with the
maintenance advantages of metal exterior window structure.
SUMMARY OF THE INVENTION
The invention is a tilting double hung window structure wherein a
single plastic guide member is inserted in the frame at each side
of the jambs and serves the multiple purposes of providing required
compression between the frame and sash to maintain the sash in
adjusted positions, guiding the sash in vertical movement and
weatherstripping between the sash and frame. The guide members in
conjunction with unique two-part camming and locking structure
further permit tilting of the sash into substantially any desired
position with relative ease to facilitate cleaning of the window.
The window structure of the invention uses a minimum number of
separate parts which parts are uniform where possible and are metal
on the exterior and wood on the interior to provide weather
resistance and aesthetic appearance.
The sash of the double hung window structure of the invention are
reglazable to which end there is provided a unique single piece
glazing member. In addition, the window structure of the invention
may be installed side by side by use of a single, particularly
efficient mullion strip. Further, the installation of the window
structure is facilitated by the provision of packing and shipping
clips during the manufacture of the window which maintain the frame
dimensions with respect to the sash during storage, shipment and
installation to prevent installation of the window with the frame
deformed so as to hinder operation of the sash in the installed
frame.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The window structure 10 of the invention includes a window frame
12, a pair of window sash 14 and 16 and guide members 18 and 20.
The frame 12 is metal, the sash 14 and 16 are wood, and the guide
members 18 and 20 are plastic. The frame, sash and guide members
when assembled, as illustrated in FIGS. 3 and 4, provide a tilting
double hung window, the sash of which may be pivoted inwardly for
cleaning or for subsequent tilting and removing as desired. In
addition, as shown best in FIGS. 3 and 4, the window structure 10
combines the advantages of a metal exterior and a wood interior so
that maintenance is kept at a minimum and the natural beauty of
wood is preserved.
More specifically, the frame 12 includes the head member 22, the
jamb members 24 and 26 and the sill member 28. The head and jamb
members have a single cross section, as illustrated, including a
mounting flange 30 to aid in installation of the window structure
10 in a building opening, an exterior molding portion 32 and
portions 34, 36, 38 and 40 forming pockets 42 and 44 for receiving
the guide members 18 and 20.
The sill member 28 includes the outwardly and downwardly inclined
portion 46 and the portion 48 for securing the sill in a building
opening. A water-stop portion 50 is provided on the cross section
of the sill 48 and a molding receiving portion and sash stop member
52 is provided on the inside of the sill member 28. The head, jamb
and sill members 22, 24 and 26 and 28, as shown, may be mitered and
connected by convenient corner structure (not shown).
The sash 14 and 16 are exactly the same and each includes head,
jamb and sill members 54, 56, 58 and 60. The head, jamb and sill
members are provided with recesses 62 in which glass panes or other
building panels 64 are secured by means of the glazing member 66,
as shown best in FIG. 5, in the case of single thickness glass
panes. Insulated window panes 68 may also be secured in the
recesses 62 in the sash, as shown in FIG. 3, by means of a glazing
structure 70.
The glazing strip 66 is shown in more detail in FIG. 5 and has a
generally U-shaped cross section with one leg longer than the
other. The longer leg terminates in a pointed portion 68 extending
outwardly from the longer leg of the cross section and away from
the shorter leg of the cross section. The terminal portion 70 of
the shorter leg of the cross section of the glazing strip 66
extends at an acute angle to the shorter leg toward the connecting
portion of the U-shaped cross section and away from the longer leg
thereof, again as shown in FIG. 5. The connecting portion of the
U-shaped cross section of the glazing strip 66 terminates on the
longer leg side of the cross section in a pointed portion 72 and
extends outwardly of the U-shaped cross section from the shorter
leg in a portion 74, again as shown in FIG. 5.
The particular cross section of the glazing strip 66 permits
glazing of the sash 14 and 16 with glass panes or similar building
panels having substantially varying thickness. Thus, the pointed
portions 68 and 72 provide excellent weather-seals, the portion 70
is flexible to accommodate panels of different thickness and
further provides a sealing function, while the portion 74 of the
cross section of the glazing strip provides a finished appearance,
even with building panels of considerably different thickness.
In use, as will be seen subsequently, the sill of the sash 14 and
16 is secured in place by means of screws passing through the
camming and locking structure illustrated in FIGS. 6 through 9.
Thus, in reglazing the sash 14 and 16, it is merely necessary to
remove the glazing strips 66, remove the sill of the sash, place a
new pane of glass in the recesses 62, replace the sill and press
the glazing strip 66 into position around the sash in the recesses
62, as shown in FIG. 5.
At the bottom of both the sash member 14 and the sash member 16, as
shown in FIG. 6, the camming and locking structure 76, which is
best shown in FIG. 9, is provided to permit pivoting the sash
relative to the guide members 18 and 20 and the frame 12.
The camming and locking structure 76 includes the separate camming
member 78 and locking member 80. The camming member 78 is secured
to the sill of the sash, as shown in FIG. 6, by the portions 82 and
84 which are positioned a substantial distance apart on the base
portion 86 of the camming member 78 and are adapted to be driven
into the sills in the position shown in FIG. 6. The cylindrical
portion 88 of the camming member 78 of the camming and locking
structure is provided to react against a portion of the guide
members as shown in FIG. 8, on tilting of the sash to which it is
secured. The opening 90 is provided in the other end of the
cylindrical portion 88 of the camming member 78 to receive the
mounting screw 92 by which the locking member 80 of the camming and
locking structure 76 is secured to the camming member 78, the
camming and locking structure 76 is secured to the sash and the
sill of the sash is secured to the jambs thereof.
The locking member 80 of the camming and locking structure 76, as
shown in FIG. 9, is an elongated member having an opening 94 in one
end thereof with an outer enlarged diameter for receiving the head
of the screw 92 and a reduced inner diameter fitting over the
bearing portion 96 of the cylindrical portion 88 of the camming
member 78, whereby the locking member 80 is pivoted to the camming
member 78. The cylindrical extension 98 of the locking member 80
permits ready connection of the camming and locking structure to
the window counterbalance structure 100, as shown in FIG. 6, by
means of the hook 102 which may be readily engaged and disengaged
therefrom should it be desired to remove the sash 14 or 16 from the
frame 12. Serrated edges 104 are provided on the locking member 80
of the camming and locking structure 76, whereby on tilting of the
sash, as shown in FIG. 8, so that the camming member 78 engages one
portion of the guide strips, the serrations are forced into
engagement with an adjacent portion to lock the sash in a
predetermined vertical position during tilting thereof.
The guide members 18 and 20 are constructed of a resilient plastic,
such as a semi-rigid vinyl, nylon or the like. The guide members
have a cross section illustrated best in FIG. 4, including a pair
of longitudinally extending recesses 106 and 108 for receiving the
camming and locking structure 76. The members 18 and 20 are further
provided with lesser recesses 110 and 112 for receiving the edge
portions 114 and 116 of the jambs of the sash 14 and 16, whereby
the sash are guided in vertical movement within the frame 12, as
previously indicated.
The arcuate resilient portions 118, 120 and 122 of the guide
members 18 and 20 extend into the pockets 42 and 44, as shown, and
tend to urge the members 18 and 20 out of the pockets 42 and 44 and
into engagement with the jambs of the sash 14 and 16. The direction
in which the arcuate portions 118, 120 and 122 are bent and the
resiliency thereof provide weathertight window structure between
the frame 12 and sash 14 and 16.
The frame portions 36 and 38 are provided with projections 124 and
126 thereon extending into the pocket 42 which mate with abutments
128 and 130 on the portions 118 and 120 of the guide members 18 and
20 to maintain the guide members 18 and 20 within the pocket 42.
Similar projections 132 can be provided on the portion 40 of the
frame jambs 24 and 26 and on the portions 122 of the guide members
18 and 20.
Locking structure 134 is provided operable between the sashes 14
and 16 in the closed position and weather-stripping 136 and 138 is
provided as desired to maintain a weathertight window.
The window structure 10 is completed by the wood interior molding
140 secured over the portions 40 and 52 of the head, jamb and sill
members 22, 24, 26 and 28 of the frame, as shown in FIGS. 3 and
4.
In overall operation, with the locking structure 134 unlocked, the
inner sash 14 may be grasped by the head and pulled inwardly to
pivot about the camming and lock structure 76 at the bottom thereof
on forcing of the portion of the guide members 18 and 20 supported
primarily by the portions 122 inwardly of the pockets 44. Thus,
either surface of the window pane 68 may be exposed on the inside
of the window structure 10 for cleaning or the like, as shown in
FIG. 2. On lowering the upper sash 16, the head of the upper sash
16 may be gripped and the upper sash pivoted about the camming and
locking structure 76 adjacent the bottom thereof to urge the
portion of the guide members 18 and 20 supported primarily by
portions 118 and 120 into the pockets 42. Again then both surfaces
of the window pane 64 in the upper sash 16 may be exposed for
cleaning or the like on the inside of the window structure 10.
With the windows in the tilted position, as shown in FIG. 2, they
may be further inclined so that one side is raised higher than the
other, whereby the camming and locking structure 76 may be removed
from the recesses 106 and 108 and the sash 14 and 16 completely
removed from the window structure 10 for replacing, repairing or
the like.
Conversely, when it is desired to close the window structure 10,
the sash are first placed in the frame 12 with the locking and
camming structure 76 in the recesses 106 and 108 to provide a
horizontal pivot axis for the sash, and the sash is then pivoted
back into the vertical position with the guide portions 114 and 116
of the sash within the recesses 110 and 112 of the guide members 18
and 20. The lower sash may then be moved all the way to the bottom,
as illustrated in FIG. 3, the upper sash may be moved all the way
to the top and the locking structure 76 latched, whereby the bottom
of the lower sash is secured due to the camming and locking
structure 76. The top of the lower sash and the bottom of the upper
sash are secured due to the pivot pins adjacent the bottom of the
upper sash and the latch structure 134 and the head of the upper
sash is secured due to the placing of the head of the sash of the
pocket 42 in the head member.
When it is desired to install two of the double hung tilting window
structures 10 side by side, as illustrated in FIG. 10, the
installation may be rapidly accomplished in a water-tight manner by
use of the mullion strip 142, illustrated best in FIGS. 11 and 12.
The mullion member 142 has a cross section, as shown in FIG. 12,
which is generally H-shaped having the cross bar portion 144 and
the opposite end portions 146 and 148. The end portion 146 is
terminated with portions extending inwardly toward each other and
terminating in points, while the end portion 148 is outwardly
concave, as shown in FIG. 12.
In installation, the first window structure 10, for example the
window at the left side in FIGS. 10, 11 and 12, is installed in the
usual manner after the mounting flange 30, as shown best in FIG. 4,
has been partly broken off. The end portion 146 of the H-shaped
cross section of the mullion member 142 is then engaged with the
remainder of the mounting flange of the left window 12, as shown in
FIG. 12. Subsequently, the remainder of the broken off mounting
flange of the right hand window structure 10, as shown in FIG. 10,
is inserted in the end portion 148 of the H-shaped cross section of
the mullion member 142 and the window structures 10 are urged
together, while the second window 10 is fixed in place.
Due to the configuration of the cross section of the H-shaped
mullion strip 142, including the pointed end portions 146 and the
concave outward end portions 148 which at their closest point are
closer together than the width of the cross bar 144, the mullion
strip snugly engages both broken off mounting flanges of the
windows 10 in assembly, as illustrated in FIG. 11, to provide a
water-tight vertical barrier for the window structures in side by
side installation.
It will be understood that additional windows may be similarly
installed and that if it is desired to install a pair or more
windows at angles, such as 15.degree. and 45.degree. with respect
to each other, such installation can be accomplished with mullion
strips similar to mullion strip 142 and, for example, I-shaped
mullion members having the desired angle positioned between the
windows.
In shipment of the double hung tilting window structure 10, it is
particularly desirable to maintain the frame in a predetermined
relation to the sash so that when the window structure 10 is
installed, the proper compression will be applied to the sash by
the guide strips 18 and 20 to permit easy movement of the sash. In
accordance with the invention, the dimension between the frame 12
and the sash 14 and 16 is maintained by the exterior packing and
shipping clip 152 and the interior packing and shipping clip 154,
as shown best in FIGS. 16 and 17, respectively.
The exterior packing clip 152 includes the flat portion 156 adapted
to extend horizontally of the window structure illustrated in FIG.
10 in position thereon and having the nailing opening 158 extending
therethrough. The flat portion 160 of the clip 152 extends
perpendicular to the portion 145 and is terminated in a sharp
flange 162 on one side, as shown in FIG. 16.
In installation, as shown in FIG. 15, the sharp flange 162 of the
packing clip 152 is inserted in the recess 164 extending
longitudinally of the frame jambs 162 and the flat part 156 of the
clip 152 is placed in surface to surface engagement with the bottom
surface of the sill of the upper sash 16 in the upper position
thereof and is secured in place by convenient means, such as nail
166. The frame 12 is thus not allowed to bow outwardly of the
sash.
The packing and shipping clip 154 includes the three relatively
perpendicularly flat portions 168, 170 and 172, connected as shown
in FIG. 17. The plane 172 is substantially triangular and the plane
170 includes a fastener notch 174 extending thereinto from one edge
thereof. Rectilinear portion 176 extends in the plane of portions
168 and 170 of the clip 154 and through the plane of portion 172
thereof at the intersection of the planes, as shown. The portion
168 of the clip 154 terminates in a flange 178 extending at right
angles thereto.
In use, as shown best in FIG. 14, the interior packing and shipping
clip 154 is positioned with the portions 168 and 170 in surface to
surface engagement with the inside of the jamb of the sash 14 and
the surface 180 of the wood molding 140 with the rectilinear
portion 176 positioned bewteen the jamb and molding and the flange
178 engaging the jamb, as shown in FIG. 14. The clip is then
secured in place by fastening means, such as the nail 182. The sash
14 and the frame 12 are thus rigidly secured in predetermined
relation for shipment and storage to insure proper
installation.
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 embodiments and modifications as are defined by the
appended claims within the scope of the invention.
