Claims
I claim:
1. A sheet metal fastener for application to a nailable surface
comprising a centrally located sheet metal strap, a laterally
extending bendable shank integral with each end of the centrally
located sheet metal strap, said shanks inclined upwardly and
outwardly from the ends of the centrally located sheet metal strap,
integrally formed nails at the outer end of each shank, said nails
disposed generally vertically downwardly and curved slightly
inwardly toward each other, said nails having sharp points at their
lower ends, said nails reinforced with generally spaced-apart
parallel side flanges located above the points and extending
outwardly at substantially right angles from the nail body, said
shanks reinforced with side flanges which are downwardly and
inwardly flattened against the bottom surface of the shanks, said
shank side flanges constituting extensions of the side flanges of
the nails.
2. A fastener as set forth in claim 1 in which the centrally
located sheet metal strap is U-shaped to encircle an object to be
fastened to the nailable surface.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The fastener of this invention is used to engage wood members and
to attach pipe or electrical conduit to wooden or other material
nailable surfaces. It may be used as a substitute for ordinary
toenailing as well as being a replacement for the long existent
fastener which has a U-shape center and side extensions with holes
therethrough. These prior fasteners are used with separate nails. A
user was therefore required to hold three separate items (a
fastener, a nail, and a hammer) at one time in order to apply the
pipe fastener. With the present device the integral nails reduce
the parts to be held to two, making it easy to apply. The invention
resides in the construction of the bendable shanks and integral
nails.
2. Description of the Prior Art
The only basically similar device is shown in U.S. Pat. No.
3,416,821. However, the present device is formed with a combination
of flange treatments with an optional pipe encircling U-shaped
center.
SUMMARY OF THE INVENTION
A principal object of this invention is to provide a new and
improved fastener for engagement with a nailable surface.
An important object of this invention is to provide a novel
fastener for wood in which there is a center strap having bendable
shanks on each end of the strap and with an integral nail on the
outer end of each shank.
An important object as set forth in the preceding paragraph in
which the bendable shanks and integral nails employ a combination
of flange treatments for reinforcement.
An important object of this invention is to provide a formed sheet
metal member to provide a pipe holding portion and including
integral clinching type nails on each side of the pipe holding
center portion.
It is a further important object of this invention to provide a
U-shaped sheet metal member to snuggly engage and hold a pipe
therein and have integrally formed nails at the outer ends of
bendable shank portions to permit the application of the fastener
over a pipe and to a wooden or other material surface capable of
nail penetration.
Other and further important objects and advantages will become
apparent from the disclosures in the following specification and
accompanying drawings.

AS SHOWN IN THE DRAWINGS
The reference numeral 10 indicates generally a centrally located
sheet metal strap optionally formed with an inverted U-shape 11 and
laterally extending shanks 12 and 13 projecting outwardly and
somewhat upwardly from the lower ends of the legs of the center
portion 11. At the outer end of the bendable shank 12 there is an
integrally formed nail 14 which is disposed generally vertically
and projects downwardly. The nail 14 is curved slightly inwardly.
At the outer end of the shank 13 there is an integrally formed nail
15 which projects downwardly in a substantially vertical position
comparable to the nail 14. Both nails are curved slightly inwardly
toward each other so that when they are finally driven into nail
receiving members such as wood there is a clinching action.
The integral nail 14 is formed with a sharp point 16. The outer
surface of the point 16 is preferably milled or serrated to
prohibit a slipping of the nail within the wood into which it is
ultimately driven. The nail 14 is provided with generally parallel
spaced-apart side flanges 17. These side flanges are disposed at
generally right angles to the back body portion of the nail 14 and
act as reinforcing members for the fabricated integral nail. The
underside of the shank 12 is provided with turned in side flanges
18 which are generally flattened with respect to the top surface of
the shank 12. These side flanges 18 are continuations of the raised
side flanges 17 on the nail portion of the fastener. The flanges on
both the nail and the shank constitute reinforcements for the
fastener of this invention.
The nail 15 is provided with a sharp point 19 which is preferably
similarly milled or otherwise roughened on its outside as is the
point 16 of the nail 14. The nail 15 is provided with raised side
flanges 20 located above the point 19 and extending upwardly to
substantially the juncture between the nail and the shank 13.
Similarly flattened side flanges 21 of the shank 13 constitute
extensions of the side flanges 20 of the nail 15. The flanges 17
and 20 of the nails 14 and 15 are preferably bent at an angle of
approximately 90.degree. relative to the back or body portion of
the nails whereas the side flanges 18 and 21 of the shanks 12 and
13 respectively are folded downwardly and thence inwardly and
flattened against the bottom surface of the shanks. This
construction causes great reinforcement and rigid construction for
the preformed nails on the pipe or conduit fastener of this
invention.
As best shown in FIGS. 5 and 6 the fastener 10 is shown applied to
a wood member 22 and holding a pipe or conduit 23 to the wood
member. In the application of the device of this invention the
inverted U-shaped center portion 11 is slipped over a pipe or
conduit and the operator drives the integral nails 14 and 15 into
the supporting wood member by means of a hammer or other pressing
or impact equipment. The fact that the nails are formed integrally
with the U-shaped clamping portion of the fastener makes them very
convenient to use inasmuch as the user does not have to hold a
separate nail and attempt to balance both a fastener, a nail and a
hammer with two hands. The U-shaped center portion of the fastener
is preferably designed to provide for snuggly holding pipe or
conduit therein and the geometry of the nails is such that when
they are driven into the back up wood the fastener actually
clinches within the wood thereupon securely holding the pipe 23 to
the wood support 22.
