Description
The present invention relates to metallic siding of the type which
is widely used on the exteriors of houses and other structures and
more particularly to an improved trim strip for securing a piece of
siding below a window sill or other horizontal projection.
A widely used form of metallic siding consists of horizontally
extending metal strips which are formed to duplicate the appearance
of wooden clapboard siding. Each siding strip is formed with a
downwardly projecting lip near its upper edge for receiving a
mating upwardly projecting lip at the lower edge of the next higher
piece of siding. Each piece of siding extends a short distance
above the lip to provide a nailing strip for securing the siding to
the building wall. Thus, the nails are all concealed and a neat
appearance is achieved. However, when the siding is being fitted
around a window or other projection from the structure wall, the
upper edge of the siding panel terminates immediately below the
sill or other projection and there is no covering piece to shield
the nails which are employed to hold this piece of siding in place.
Nailing through the exposed portions of this siding member is
undesirable since the nails invariably cause wrinkling or dishing
of the siding panel, detracting from its appearance, or otherwise
being objectionable in appearance.
It is the primary object of the present invention to provide an
attractive trim strip for use with metallic siding which may be
positioned immediately below a window sill or other horizontal
projection of a building structure to receive and hold the upper
end of a siding panel or other member by a sliding or "floating"
connection therewith.
It also is an object of the invention to provide a trim strip which
may be nailed to the building structure in such a manner that the
nails are concealed when the siding panels are installed.
A further object of the present invention is a provision of a trim
strip for retaining a piece of siding below a window sill or other
projection which eliminates the need to nail the upper end of the
siding panel and for providing an attractive finished
structure.
The above and other objects of the invention will become apparent
in the following detailed description and are achieved by providing
a trim strip which consists, essentially, of a metallic strip which
has a substantially flat body portion, a lip portion bent from the
upper edge of the body portion in generally U-shaped relation to
the body portion, and terminating in an inwardly curled edge. The
lip portion extends somewhat less than half the height of the body
portion so that the lower part of the body portion may be nailed
directly to the building. The upper edge of a siding panel is
provided with outwardly projecting lugs or fingers that are slid or
forced upwardly between the body portion and curled edge on the lip
portion of the trim strip so that the lugs or fingers engage the
bent or curled edge portion of the trim strip.
For a more complete understanding of the invention and the objects
and advantages thereof, reference should be had to the following
detailed description in the accompanying drawings wherein there is
shown a preferred embodiment of the invention.
In the drawings:
FIG. 1 is a perspective view of the trim strip of the present
invention;
FIG. 2 is a fragmentary elevational view of a wall structure
showing the trim strip positioned immediately below a window sill
preparatory to inserting a siding panel into the trim strip;
FIG. 3 is a vertical sectional view of the panel of FIG. 2;
FIG. 4 is a vertical sectional view of the assembly of FIG. 2,
showing the siding panel in its installed position;
FIG. 5 is a vertical section on line 5--5 of FIG. 2; and
FIG. 6 is a view taken on line 6--6 of FIG. 5.
It will be understood that, while in the following description
reference is made to clapboard style siding and to the use of the
trim strip below a window sill, the invention is not limited to
this embodiment. Rather, the trim strip of the present invention
may be used wherever it is desired to secure a metallic panel along
a projecting member. For example, the strip is also ideally suited
for securing a fascia strip to the upper edge or corner means of a
wall.
Referring to FIG. 1, the trim strip of the present invention,
designated generally by the reference numberal 10, will now be
described. The strip 10 is formed of a length of sheet metal and
has a substantially flat body portion 12. The body portion 12 may
be provided with horizontally extending stiffening ribs 14 and with
a horizontally extending series of holes 16 for receiving nails 18
employed to secure the strip to the building wall. At the upper end
to the body portion 12, the strip is bent to form a lip 20
extending in U or V-shaped relation to the body portion and
terminating in a curled end portion or flange 22 which is bent or
curled first toward the back portion 12 and then toward the front
or lip 20, as indicated at 24. A narrow gap 25 is provided between
the end portion 22 and the main portion 12 of the strip 10.
A siding panel 26 adapted to be used with the trim strip 10 is
shown in FIGS. 2, 3 and 4. This panel 26 has a body portion 27
which terminates its lower end with an upwardly projecting lip 28
and which is provided at its upper end 29 with a series of
outwardly projecting fingers or lugs 30. These lugs 30 are suitably
cut or pressed out from the panel and are formed so that their
lower edges face downwardly and terminate ouwardly of the surface
of the body portion 27 of the panel.
Referring now to FIGS. 2 and 4, the use of the trim strip 10 of the
present invention will now be described. FIG. 2 illustrates a
portion of the external wall of a structure which is covered with
an existing siding 32 and which has a window 34. A sill 36 is
provided at the bottom of the window and projects outwardly beyond
the surface of the siding 32. The numeral 38 designates a siding
panel which has been installed on the existing wall below the
window 34. This panel is of conventional construction and is
provided with a downwardly projecting lip 40 near its upper edge
and a series of holes 42 along its upper edge for receiving nails
44 to secure the siding panel 38 to the building wall. The trim
strip 10 is secured to the wall by means of the nails 18 with the
upper edge of the strip abutting the lower edge of the sill 36. A
siding panel 26 is then cut to the proper height to extend between
the lip 40 of the previously installed panel 38 and the lower edge
of the sill 36 and it is made of the sill width. The aligned
projecting lugs or fingers 30 are then suitably formed in the upper
end of the panel 26. The upper end 29 of the panel 26 is inserted
into the groove 25 between the body portion 12 and the curled or
bent end portion or edge 22 of the trim strip. The panel 26 is then
forced upwardly so that the lugs 30 are forced up beyond the end 24
of the lip of the trim strip. At the same time, the upwardly
projecting lip 28 at the lower end of the panel 26 is engaged by
the downwardly projecting lip 40 of the previously installed panel
38. Or the panel 26 can be slid into engagement with the trim strip
and panel 26. The end portion 24 of the trim strip lip engages the
lower edges of the lugs 30 and thus serves to retain the panel 26
in place. It will be noted that the nails 18 which secure the trim
strip in place are now covered by the panel 26 and therefore do not
detract from the appearance of the paneling. Additional panels 46
may now be installed to complete the wall covering and form a neat,
attractive facing for the building.
While the panel 26 has been described as being a separate panel cut
to fit the space between the trim strip 10 and a previously
installed lower panel 38, it is also contemplated that the panel 26
may merely be a portion of a longer panel. This is a preferably
arrangement as it avoids joints between adjacent horizontal panels
below the windows. In such a situation, a notch is cut into the
upper edge of a horizontal panel with the notch width being equal
to that of the window sill. The lugs 30 are then formed along the
upper edge of the notched portion of the panel and the panel is
installed in the same manner as has been described.
While only the best known embodiment of the invention has been
illustrated and described herein, it will be understood that the
invention is not limited thereto or thereby. Reference should
therefore be had to the appended claims in determining the true
scope of the invention.
