PANEL MOUNTING APPARATUS
Abstract
Apparatus for mounting panels, such as windowpanes and the like
for either inner or outer glazing. One form of the apparatus may
comprise a base rail having formed therein a relatively wide
dovetail groove together with a second dovetail groove in
approximately the center of the first such groove. An outer rail
seats slidably on the base rail and has a projection which engages
a portion of the inner dovetail groove and an additional projection
which engages one element of the outer dovetail groove whereby the
outer rail is secured thereto. A glazing rail is secured to the
other portion of the first dovetail groove formed in the base rail
and is likewise secured in a recess carried by the outer rail. A
space is left between the glazing rail and outer rail in which
panels, such as window glass and the like, may be inserted. The
securing portions of the glazing rail and the outer rail are
fashioned so that they may be reversed in their relationship to the
base rail should conditions warrant.

Description
BACKGROUND OF THE INVENTION
The present invention was designed to provide apparatus which can
be used to mount panels and especially window glasses in
circumstances which require outside glazing, as well as in
circumstances which require inside glazing.
In ordinary single-story or even two-story building structures, it
has long been the custom to seal or glaze windows and doors in the
structure from the outside. In such conditions the glazing work was
not often a major problem when it became necessary to replace the
window glass, since all that was necessary to reach the window for
glazing was, at most, stepladders, and in many cases glazing could
be accomplished from the ground.
Circumstances are quite different, however, when high-rise
buildings are considered. Here, if windows are glazed from the
outside a substantial amount of equipment must be used in glazing
replaced windows should this kind of activity become necessary.
Recognizing this problem and the dangers attendant to outside
glazing in elevated windows, many building codes now require that
windows above the third floor or even above the second floor be
glazed on the inside.
In view of these building restrictions, and further in view of the
fact that it is still desirable to glaze on the outside when
conditions and imposed restrictions allow, builders and
warehousemen have found it necessary to stock two different kinds
of window mounts for alternate usage, depending upon whether the
glazing will be on the inside or on the outside. This redundancy in
inventories has the obvious disadvantage of increasing costs and
also introduces the possibility of mistakes in installation of
window framing. Moreover, the cost of extrusion dies for
manufacturing the various rails is necessarily high, since the
rails necessary for inside glazing are of different geometry than
those used for outside glazing. The advantages of window framing
which could be used for both inside and outside glazing are, in
view of this explanation, at once apparent, although until the
present invention, totally satisfactory apparatus for achieving
this desired result had long remained an elusive desideratum. It is
therefore an object of the present invention to provide panel
mounting means which may be used for both inside and outside
glazing.
Another object of the present invention is to provide panel
mounting apparatus which is relatively simple to install and is of
universal application.
Still a further object of the present invention is to provide panel
mounting apparatus which can be extruded from molten aluminum and
which can be produced relatively economically.
Yet a further object of the present invention is to provide
apparatus for mounting panes of glass in buildings which is easy to
install, relatively rigid in construction, and pleasing to the eye.
These and other objects of the present invention will be readily
apparent from a careful examination of the following written
specification which is to be read in conjunction with the
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematic elevational view of a window showing the
relationship of the structures embodying this invention to the
window panes.
FIG. 2 is a partial cross-sectional view taken along line 2--2 of
FIG. 1 showing one way in which panel mounting apparatus embodying
this invention may be assembled.
FIG. 3 is a cross-sectional view taken along line 3--3 of FIG. 1
similar to FIG. 2 in which elements of the panel mounting apparatus
have been reversed and a different type of supporting rail is
utilized.
DESCRIPTION OF AN EMBODIMENT OF THE INVENTION
The present invention has utility in many types of construction
environments. One such type is shown in FIG. 1 wherein there is
disclosed a double hung window of generally standard design. The
double hung window includes the usual foot rail 10 and head rail 11
which intercept a pair of parallel jamb rails 12 to form a
rectangular window frame. The central portions of jamb rails 12 are
connected by a meeting rail 13 to divide the rectangular frame into
an upper and lower portion. Window panes 14 and 15 are secured
within the upper and lower portions respectively by the apparatus
disclosed hereinafter.
An important characteristic of the present invention is the fact
that, although the basic structure of the head rail, foot rail,
jamb rail, and the meeting rail may be different, the apparatus
embodying the present invention may be used with each type of rail
without change in the form of the apparatus.
In FIG. 2, for instance, there is shown a portion of a meeting rail
13 on which structure embodying the invention is mounted. In
general, this structure includes a longitudinally extending outer
rail 21 on which is seated a window pane 22. Lying opposite the
rail 21 is an elongated glazing rail 23 which likewise seats upon
the meeting rail 13. Putty or glazing material 24 is used to seal
between the outer rail 21 and the window pane 22 in the manner
shown. An important feature of the present invention resides in the
fact that outer rail 21 and glazing rail 23 may be reversed with
respect to base rail 11 so that glazing material 24 may appear to
the right as viewed in FIG. 2 rather than to the left. This may be
done without disturbing the position of meeting rail 13. An example
of this arrangement of elements is disclosed in FIG. 3 which will
be discussed in more detail hereinafter.
As pointed out earlier, the supporting or base rail may take any
one of several different forms whether it be head, jamb, or meeting
rail. In any event, however, the base rail is characterized by a
longitudinally extending flat 31 on both edges of which there are
provided parallel longitudinal dovetail projections 32 and 33.
These dovetail projections are undercut in the standard manner to
receive portions of the outer rail and glazing rail whereby these
members are secured to base rail 10. In viewing the cross-sectional
configuration of this portion of the apparatus as shown in FIG. 2,
it will be appreciated that projections 32 and 33 are oppositely
faced and together define a relatively shallow, wide dovetail
groove, the bottom of which is flat 31. The second dovetail groove
34 is located in the center of flat 31 and extends parallel to
dovetail projections 32 and 33. Groove 34 functions to receive a
portion of outer rail 21 whereby rail 21 is secured to the surface
of base rail 10 by the cooperative action of dovetail projection 33
and groove 34 in a manner to be hereinafter described. After the
outer rail 21 is placed in the illustrated position, it is often
desirable to peen the base flange thereof overlying the flat 31 so
that it is retained against longitudinal sliding movement on the
base rail.
Outer rail 21 comprises an outer web 41 which extends the length of
rail 21. At the upper edge of web 41 there is provided a lip 42
which projects inwardly toward window pane 22 and engages the
window pane to provide bracing and stability thereto. At the lower
edge of web 41, a thickened base flange 43 extends in a direction
parallel to lip 42. Base flange 43 is divided into an upper and
lower portion by a recess 44 which opens outwardly in a direction
toward glazing rail 23 and receives a projection of the glazing
rail. The upper portion of base flange 43 serves as a base support
for window 22 while from the bottom of this flange there projects a
triangular dovetail bead 45. Bead 45 extends the length of rail 21
and is located at the edge of the plane including the inside face
of outer web 41. As shown in FIG. 2, bead 45 engages dovetail
projection 33 to aid in locking outer rail 21 to the surface of
meeting rail 13.
Additional securing means are also carried by the under portion of
base flange 43. This additional securing means is in the form of a
longitudinally extending toe 51 which projects outwardly and
downwardly from the outside edge of base flange 43, and which has
an outer surface approximately parallel to one of the downwardly
facing surfaces of dovetail groove 34.
Glazing rail 23 serves to provide stability to window pane 22. The
glazing rail includes an elongated locking flange 52 which projects
into recess 44 whereby this portion of the glazing rail is
restricted against motion toward and away from the meeting rail 13.
An inner web 53 is formed on the edge of locking flange 52 opposite
recess 44. In the upper portion of web 53 (as viewed in FIG. 2),
there is carried a deep groove 54 into which projects a portion of
a sealing bead 55. Bead 55 is formed of resilient material, such as
rubber and the like, and functions to reinforce the seal between
window 22 and glazing rail 23. The upper portion of web 53 is held
in rigid relationship to the meeting rail 13 by means of a
connecting assembly C which includes an elongated
rectangular-shaped connecting member 61 which projects in a
horizontal direction from the top edge of web 53 away from sealing
bead 55. A vertical leg 62 extends in a direction normal to the
plane of connecting member 61 and parallels inner web 53 to form a
member having a generally U-shaped cross-sectional configuration.
Along the edge of leg 62 opposite connecting member 61, there is
mounted a triangular-shaped, outwardly opening dovetail bead 63
which engages the under side of dovetail projection 32. By the
cooperating action of dovetail bead 63 and locking flange 52 and
their corresponding elements, meeting rail 13 and outer rail 21,
respectively, the glazing rail 23 is maintained in a rigid position
with respect to the other elements of the structure.
FIG. 3 shows the identical outer and glazing rails disclosed in
FIG. 2 in cooperative engagement with a jamb rail 12. The jamb rail
12 has an upper portion constructed identically to the upper
portion of the meeting rail 13. In FIG. 3, however, the positions
of the outer rail and glazing rail are reversed with respect to the
glazing rail 12, which here constitutes the base or support rail,
whereby glazing material 24 appears on the right hand portion of
the figure rather than the left. Here it will be noted that
dovetail bead 45 which forms a portion of the outer rail cooperates
with dovetail projection 32 rather than with projection 33 as in
FIG. 2. Moreover, toe 51 carried by the outer edge of flange 43
projects downwardly into the opposite side of dovetail groove 34 in
FIG. 3. Aside from these differences, however, the manner in which
the two upper rails are secured to the base rail is identical in
both figures.
It will be obvious that a number of changes and alterations may be
made in the structure shown in the drawings without departing from
the spirit and scope of the present invention. Embodiments
described herein are presented by way of an example only and the
invention is to be limited only by the appended claims.
