Claims
I claim:
1. An elongated lap siding mounting device having a transverse
section with depending flanges on its longitudinal edges, one of
said depending flanges being longer than the other, an outturned
secondary flange on the lower edge of said longer depending flange
and an arcuate seal and cushion forming configuration on the outer
side of the other depending flange, said device arranged to be
positioned on the upper longitudinal edge of one piece of lap
siding with the seal and the cushion forming configuration between
said piece of lap siding and the structure to which the lap siding
is applied and the outturned secondary flange on the longer of said
depending flanges of the device positioned beneath and in
supporting and guiding relation to a second upwardly and outwardly
disposed piece of lap siding.
2. The elongated lap siding mounting device of claim 1 wherein said
arcuate seal and cushion forming configuration includes a pair of
longitudinally extending ribs on said other depending flange and an
arcuate third flange thereon curving thereover.
3. The elongated lap siding mounting device of claim 1 and wherein
the seal and cushion forming configuration is positioned adjacent
the transverse section of the device.
4. The elongated lap siding mounting device of claim 1 and wherein
said outturned secondary flange is of a size sufficient to engage
and hold the lower edge of a piece of lap siding positioned
thereon.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention:
This invention relates to frame constructions such as used in
dwelling houses wherein horizontally extending lap siding is
applied as an exterior wall surface and more specifically to means
for sealing such siding with respect to the wall surface and
providing a guide and mounting ledge for successive pieces of
siding applied thereto.
2. Description of the Prior Art:
Prior structures of this type have largely related to clips for
holding lap siding as in patent 3,173,229 and for forming lock
seams as in patent 984,860.
This invention provides a continuous self-supporting seal between
the upper edge of a piece of lap siding and the wall to which it is
applied as well as forming a downwardly spaced support and guide
for the next piece of siding to be applied thereover and extending
thereabove.
SUMMARY OF THE INVENTION
A siding mounting strip such as inexpensively formed as a plastic
extrusion of a suitable synthetic resin such as a styrene
composition or the like is positioned in continuously extending
sections on the longitudinal upper edges of lap siding boards or
the like and includes spaced downwardly extending flanges one of
which has a guide and support for the next applied siding board and
the other of which forms a cushion seal between the siding board on
which the device is applied and the wall to which it is secured so
as to form sound and heat insulating air spaces behind the
individual siding boards and position the siding boards in
cushioned relation to the supporting structure.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective elevation of a section of the siding
mounting strip.
FIG. 2 is a vertical cross section through a portion of a frame
wall construction showing portions of two siding boards and the
device of the invention in position therebetween.
DESCRIPTION OF THE PREFERRED EMBODIMENT
In the simplest form of the invention a plastic extrusion includes
a transverse section 10 having a depending flange 11 on one side
with a secondary outturned flange 12 along its lower edge. A second
depending flange 13 is formed on the other longitudinal edge of the
transverse section 10 and has a pair of longitudinal ribs 14
thereon and an upturned arcuate member 15 extending thereover and
spaced with respect to the downturned flange 13.
The siding mounting strip is preferably formed as a plastic
extrusion of a suitable semi-rigid synthetic resin composition such
as the several styrene compounds that will occur to those skilled
in the art.
In FIG. 2 of the drawings, a frame wall construction is shown which
includes a studding 16, rock lath, 17 plaster 18 and sheathing 19
with a siding board 20 positioned in spaced relation to the
sheathing 19 by a fastener 21 which extends through a second siding
board 22. The siding mounting strip is illustrated in position on
the upper longitudinal edge of the siding board 20 with the
transverse section 10 lying on top of the upper edge of the siding
20 with the cushion formed by the arcuate flange 15 being
positioned between the siding board 20 and the sheathing 19 and the
downturned flange 11 being positioned between the siding board 20
and the siding board 22 with the lower edge of the siding board 22
being positioned on the outturned flange 12 thereof.
The fastener 21 is a siding nail positioned through the siding
boards 22 and 20 respectively and through the sheathing 19 and into
the studding 16 as customary in frame wall constructions. It will
be observed that when the siding board 20 is applied to the wall it
has a longitudinal section of the siding mounting strip as
hereinbefore described positioned on its uppermost edge where it
will be self-retaining. The siding board 20 is leveled and secured
by fasteners as customary. The siding board 22 is then positioned
with its lower edge on the outturned flange 12 of the siding
mounting strip where it is automatically leveled and properly
spaced for the desired overlap as customary in lap siding frame
wall constructions. A nail 21 comprising a fastener is then
positioned through the lower portion of the siding board 22, the
upper portion of the siding board 20 and into the sheathing and
studding construction of the wall to secure the assembly in the
position shown.
The resulting construction includes a longitudinal air seal formed
by the arcuate flange 15 and individual air spaces S behind each of
the siding boards.
Those skilled in the art will observe that the air spaces S form
sound and heat insulation between the siding and the wall and that
the efficiency of the wall is thereby improved. It will also be
observed that the cushioning effect created by the sealing action
of the curved flange 15 enables the assembled wall to resist
separation as would occur from expansion and contraction or warpage
of the component parts. The irregularities in the plane of the wall
surface are also overcome by positioning the fasteners at different
locations so as to change the degree of compression of the curved
sealing flange 15 and thus bring the finished siding surface into
desired straight line arrangement.
Considerable insulating value is added to a wooden wall structure
by utilizing the present invention as tests on a sample wall formed
in accordance with the invention with an outside temperature of
170.degree.F. and an inside temperature of 70.degree.F. revealed
that at the end of 1 hour the inside temperature had risen
1.degree. to 71.degree. at the end of three hours the temperature
rise was 2 additional degrees to 73.degree..
A comparable test of the same components without the device of the
invention starting with 170.degree.F. outside temperature and a
70.degree.F. inside temperature showed an 11.degree. inside
temperature rise in 1 hour to 81.degree.. Tests with respect to
time saved in applying siding utilizing the siding mounting strip
indicate that approximately 20 percent of the time spent in
applying lap siding is used in leveling, aligning and spacing the
individual horizontally extending siding boards which actions are
completely eliminated through the use of the present invention as
the siding boards are automatically supported, aligned, leveled and
conveniently held for fastening enabling a carpenter to apply
considerably more lap siding in the same time than would otherwise
be the case.
Although but one embodiment of the present invention has been
illustrated and described it will be apparent to those skilled in
the art that various changes and modifications may be made therein
without departing from the spirit of the invention.
