Description
BACKGROUND OF THE INVENTION
It is well known in the construction art that extruded plastic and
aluminum trim can be used on door molding, window frames, sills,
and the like. Such extruded trim can be used in "trimming out" any
penetration of a wall or any intersecting surfaces within a house
or other structure. Most known trim requires a considerable amount
of labor and time to install. The trim must be nailed to the
intersecting surfaces of window frames and door frames and then
must be nailed to the wall surrounding the frame. Nail holes must
be puttied, and the trim precisely fitted to conform to the
structured frame. If the window sill is not completely "plumb" or
square, a much greater amount of time and labor is required to trim
the frame.
It is an object of the present invention to provide an article of
manufacture for quickly and economically covering or lining a door
frame or window frame, or any two intersecting surfaces in
general.
It is another object of the present invention to provide an article
of manufacture for quickly and economically lining a door frame or
window frame which is not plumb or square.
THE INVENTION
In accordance with the present invention there is provided a liner
for covering one of two intersecting surfaces including a face
means having an exposed side and a hidden side, a return means
having an exposed side and a hidden side connected to the face
means, and a spring means connected to the hidden face of the
return means or the face means.
The invention will be more readily understood by reference to the
drawings in which:
FIG. 1 is a cross-sectional view of the liner of the present
invention attached to a window frame;
FIG. 2 is a cross-sectional view of an embodiment of the present
invention;
FIG. 3 is a perspective view of the liner embodiment shown in FIG.
1;
FIG. 4 is a cross-sectional view of the liner of FIG. 3 taken along
lines 4--4;
FIG. 5 is a perspective view of an aligning clip;
FIG. 6 is a cross-sectional view of the aligning clip of FIG. 5
taken along lines 6--6;
FIG. 7 is a perspective view of the liner embodiment shown in FIG.
2;
FIG. 8 is a cross-sectional view of FIG. 7 taken along lines
8--8;
FIG. 9 is a perspective view of the liner embodiment shown in FIG.
2; and
FIG. 10 is a cross-sectional view of the liner of FIG. 9 taken
along lines 10--10.
Referring now to the drawings, the liner designated generally by
the numeral 21 of the present invention can be seen in FIGS. 1, 3
and 4. In FIG. 1, liner 21 is attached to a wood frame 36 to form a
trim or liner for the window frame 20. As can be seen in the
drawings, liner 21 is made from one integrally formed piece of
material such as metal, plastic, or the like, although plastic is
preferred. Liner 21 has a hidden inside surface 21b and an exposed
or outside surface 21a. The surface 21b inside of liner 21 shown in
FIGS. 3 and 4 has attached thereto spring members 24--24 and a
plurality of channel wall members 25. The inside surface 21b faces
the wall and window frame and can't be seen after the liner is
installed.
Liner 21 includes a liner return portion 23 connected to liner face
22. Liner face 22 forms an angle with the liner return 23 which is
slightly greater than 90.degree., as can be seen in FIG. 4. As also
shown in FIG. 4, liner face 22 is generally arcuate in
cross-section. Liner return 23 is straight, the outer surface 21a
being a plane.
The return portion 23 of the liner 21 has the two spaced apart
springs 24--24 attached to its inside surface. One or more springs
may be used, but two springs are preferred. The springs 24--24
serve to force the return portion 23 of the liner 21 snugly against
window frame edge 19 which is a part of the window frame 20.
The inside surface of liner face 22 is provided with a plurality of
spaced apart channel walls 25 which have protuberances 26 on their
ends. Located at one end of liner face 22 is liner lip 32 which
fits snugly against wall covering 37. In FIGS. 5 and 6 is shown an
aligning clip designated generally by the numeral 28, which is used
to fasten liner 21 to the wood frame 36. Aligning clip 28 includes
a clip return portion 29 which fits flush against the end of wall
covering 37 and wood frame 36. The outer end of the clip return is
provided with a clip lock 31 which is generally trapezoidal in
shape. The clip lock 31 is received between two adjacent channel
wall members 25--25. The protuberances 26--26 on the bottom of
channel walls 25--25 engage the clip lock 31 and holds the liner 21
snugly against the wall covering 37. Aligning clip 28 may also have
a transversely extending clip face 30 which spaces the clip lock 31
the proper distance from wall covering 37. Aligning clip 28 is
fastened in position by a nail 35, or a screw if desired, as shown
in FIG. 1.
As previously mentioned in the explanation of FIGS. 3 and 4, liner
face 22 is generally arcuate in cross-section. It is very important
that this cross-section be arcuate so that when liner 21 is
attached to a window, as shown in FIG. 1, liner face 22 must be
depressed downward to engage aligning clip 28. Thus liner face 22
is under stress and fits more snugly against the window frame
36.
Referring now to FIG. 2, there is shown a liner composed in general
of two elements, face element 49 and return element 50. Face
element 49 is also shown in FIGS. 9 and 10 and return element 50 is
shown in FIGS. 7 and 8. In FIG. 2, face element 49 and return
element 50 can be seen to be attached to wall covering 37 and wood
frame 36 to form a trim or liner for the window frame 20. As can be
seen in the drawings, both face element 49 and return element 50
are made from one integrally formed piece of material such as
metal, plastic, or the like, although plastic is preferred.
Return 50 is shown in detail in FIGS. 7 and 8 and also in FIG. 2.
Return 50 can be seen to have a hidden inside surface 61b and an
exposed or outside surface 61a. Surface 61b inside of return 50 has
attached thereto a spring member 44 and a lower face element 40.
Lower face element 40 has two clips 41 attached thereto for
engagement of protuberances 45a and 46a of element 49, and is
connected to return leg 43.
Face element 49 has a hidden inside surface 62b and an exposed
outside surface 62a. The inside surface 62b shown in FIGS. 9 and 10
has attached thereto a support 46 having protuberance 46a attached
thereto. Face element 49 includes a return portion 45 connected to
face 42. Face 42 forms an angle with liner return 45 which is
slightly less than 90.degree.. Return portion 45 has a protuberance
45a connected thereto. Both support 46 and return 45 are biased
toward each other so that when they are connected to return 50 they
must be spread apart to engage protuberances 45a and 46a of return
50. It is important that the distances between protuberances 46a
and 45a be slightly greater than the distance between protuberances
41--41 of return 50 so that return portion 45 and support 46 must
be spread outward to fasten face element 49 to return element 50.
As seen in FIG. 10, the arrows indicate the direction in which
support 46 and return portion 45 must be moving to attach face
element 49 to return element 50.
Aligning clip 28 and return 50 may be connected to wood frame 36 or
wall covering 37 by nailing, gluing, or any other method well known
in the art. Liner 21 can then be attached to clip 28 by merely
snapping the liner into place over the clip. Face element 49 is
connected to return 50 by spreading support 46 and return 40 in the
manner indicated by the arrows in FIG. 10 and forcing face element
49 against return 50.
