NAILING CLIP FOR PLASTIC SIDING
Abstract
Plastic siding made to simulate clapboards is now made with an
integral top locking strip having a downward projection spaced from
the body of the siding into which an upturned projecting strip, on
the bottom of the next higher course of siding, can be fitted when
applying the siding to a house. The present disclosure eliminates
this integral locking strip and provides instead small nailing
clips of a special construction which are less expensive and which
are constructed so that the siding can be nailed in place loosely,
which is desirable to permit thermal expansion and contraction of
the siding.

Claims
I claim:
1. a. In combination, a course of siding of thin, sheet-like
material made to resemble a strip of clapboard,
b. said course of siding having a top edge adapted to lie flat
against the side of a wall to which the siding is to be nailed,
c. said top edge having a number of spaced horizontal nailing
slots,
d. said course of siding having a bottom edge turned in toward the
wall and terminating in a short upturned locking strip,
e. and a number of separate, narrow nailing clips of thin
sheet-like material, one for each of said nailing slots, each clip
having a nail perforation through which a nail can pass,
f. each said nailing clip having a top edge turned in toward the
wall and overlaying the top edge of its associated course of
siding,
g. and having also a bottom edge providing a downwardly extending
projection spaced outwardly away from the top portion of the
associated course of siding and dimensioned to receive the short
upturned locking strip of the next higher course of siding,
h. and an integral projecting member on said nailing clip extending
from the body of said nailing clip through said nailing slot.
2. The invention according to claim 1,
i. said nailing perforation being opposite its associated nailing
slot.
3. The invention according to claim 1,
i. said nailing clip having a top projection extending upwardly
from the end of said inturned top edge and in contact with the wall
to which the siding is to be attached,
j. said nailing perforation being in said top projection.
4. The invention according to claim 3,
k. said inturned top edge of the nailing clip and said integral
projecting member both being slightly longer than the thickness of
the top edge of the siding, so that when the clip is nailed in
place, the siding is loosely held against the wall.
Description
A popular form of plastic siding is made to resemble clapboarding,
and consists of a number of elongated pieces or courses which are
applied in overlapping relationship, similar to clapboards, so as
to shed water. Since the plastic siding is made of thin material,
means must be provided to interlock each course as it is applied
with the next lower course. For this purpose, an integral top
locking strip is provided on each course which has a downward
projection spaced from the body of the siding into which an
upturned projecting strip on the bottom of the next higher course
of siding can be fitted when applying siding to a house. This next
course is then nailed to the house, usually to plywood sheathing
which has been applied to form the exterior walls of the house, at
a point above the top locking strip, so that the nailing is
concealed by the next higher course of siding. The nailing is
usually done through a slot provided near the top edge of each
course of siding, the purpose of the slot being to permit a certain
amount of lateral movement of the siding with respect to the wall
of the house, to provide for differential expansion and contraction
between the siding and the sheathing, which otherwise would tend to
produce buckling and distortion of the siding. For this reason, the
nail should not be applied too tightly, and this is often difficult
to achieve in practice, and may result in the undesired distortion
taking place. The present invention substitutes for the integral
locking strip a series of small nailing clips of special
construction as described below, which are less expensive, and
which are constructed so that the siding can be nailed in place
loosely, thus permitting the desired thermal expansion and
contraction.
The specific nature of the invention, as well as other objects and
advantages thereof, will clearly appear from a description of a
preferred embodiment as shown in the accompanying drawings, in
which:
FIG. 1 is a perspective drawing, partly in section, showing one
form of the invention;
FIG. 2 is a sectional view taken through another form of the
invention showing the clip applied to a wall;
FIG. 3 is a similar view of a different form of the invention;
FIGS. 4 and 5 are side and front views respectively of a different
form of clip;
FIG. 6 is a sectional view taken along 7--7 of FIG. 8, showing the
clip of FIG. 4 applied to a course of siding;
FIG. 7 is a similar view, considerably enlarged to show the details
of the clip; and
FIG. 8 is a front view showing the application of the siding to a
wall.
Referring to FIG. 1, the courses of plastic siding 2, 2a and 2b are
shown fastened to the sheathing 4 of a building wall;
alternatively, the siding could be nailed directly to the joists of
the exterior walls of the building, with a thin layer of any
suitable waterproof material between the joists and the siding.
Each course of siding is provided at its top portion with an
integral flat strip 6 which in turn is provided with nailing slots
8 by means of which each course of siding is nailed to the wall,
the nails preferably being driven not fully in so that the siding
is free to move slightly in the direction of its length relative to
the wall in accommodation to thermal or other expansion or
contraction between the wall and the siding.
The bottom part of each course of siding is formed by an inturned
strip 10 terminating in a shorter upturned strip 12 which can be
engaged with a downturned portion 14 of a nailing clip 16 to hold
the bottom part of the siding firmly in place. In a common form of
past construction, the downturned element which the upturned
portion 12 of each course engaged was itself an integral part of
the upper portion of the preceding course. For this, the present
disclosure substitutes a small nailing clip 16, preferably
pre-assembled with a nail 18 so that they can be nailed through the
slots 8 of each course of siding as it is installed, which serves
both to fasten the siding in place, and also provides a bottom hook
for engagement with the upturned portion 12 of the next course of
siding.
FIG. 2 shows at 26 a modification of the clip 16 which it resembles
in all respects except that a short leg 27 is added which fits into
the slot 8 of a course of siding 2, which is the same as shown in
FIG. 1 and is sufficiently wide to also permit nail 18 to pass
therethrough loosely. Leg 27, together with thicker leg 29 at the
top portion of the nailing clip projects sufficiently far so that
the flat portion 6 of the siding can rest loosely beneath the
nailing clip 26 even after the nail 18 has been fully driven home,
thus requiring less care on the part of the person doing the
nailing.
FIG. 3 shows still another modification, in which a second leg 35
is added to the structure of FIG. 2 to provide a more positive
support and to eliminate any possibility of the nail being driven
far enough to pinch the plastic siding against the wall. In this
case, the inturned strip 10' is shown terminated in a locking strip
12' which overlies the upturned portion 14' of the nailing clip 36.
This arrangement has the advantage that the next course of siding
is supported by the nailing clip while it is being installed.
FIGS. 4 and 5 show still another form of clip which is generally
somewhat similar to the form shown in FIG. 2, except that an extra
vertically extending nailing strip 41 is added, which is preferably
pre-assembled with nail 18, and the leg 47, corresponding generally
to leg 27 of FIG. 2 is made heavier and sturdier, so that it can
serve as the sole support for the preceding course of siding by
extending through its slot 8 as best shown in FIG. 7. This has the
advantage, among others, that the nailing strip 41 can be made
larger to provide a better target for nailing, and less danger of
damaging the clip. This construction also makes it almost
impossible to nail too tightly; it creates a "floating" siding
which does not require a backer board to support the individual
siding units.
FIGS. 6, 7 and 8 show in more detail the manner in which the clip
is applied to successive courses of plastic siding.
