Conduit clamping device

Claim 2

A clamping device for securing a conduit to a support channel having a pair of spaced legs interconnected by a web with the conduit being disposed transversely to said channel and substantially adjacent the web thereof, comprising first and second straps each having a curved portion for engaging a side of said conduit, a leg extending from one side of said curved portion, and a fastening element at the opposite side thereof; said leg of each strap having a generally U-shaped end for engaging the end of a respective one of said channel legs; an abutment flange extending from each strap leg such that when said straps are mounted on said channel on opposite sides of a conduit to be secured said abutment flanges are positionable in side by side abutting relation with the abutment flange of said first strap being on an opposite side of said second strap flange than the curved portion of said first strap is located with respect to the curved portion of said second strap whereby said strap legs are prevented from moving outwardly relative to each other and the conduit therebetween; and means for securing said strap fastening elements to rigidly clamp said conduit between said strap curved portions and hold said abutting flanges in rigid engagement.

Claim 3

The clamping device of claim 1 in which said fastening element of each strap includes a fastening flange extending from said curved portion, said fastening flange of each strap being formed with an aperture, and a screw captively carried in the aperture of one of said straps for threadable engagement with the aperture of the other of said straps.

Claim 4

The clamping device of claim 2 in which said screw has a tapered self-tapping end.

Claim 5

The clamping device of claim 5 in which said screw has a uniformly threaded section immediately adjacent said tapered self-threading end for receiving a nut.

Claim 6

The clamping device of claim 4 in which said screw has a reduced diameter unthreaded portion between said uniformly threaded section and the head thereof, and said screw is captively held in said strap flange at said reduced diameter portion for limited relative movement.

Claim 7

The clamping device of claim 1 in which said straps are of identical construction.

Claim 8

A clamping device for securing a conduit to a support channel having a pair of spaced legs interconnected by a web with the conduit being disposed transversely to said channel and substantially adjacent the web thereof, comprising a pair of straps each having a curved portion for engaging a side of said conduit, a leg extending from one side of said curved portion, and a fastening element at the opposite side thereof; said leg of each strap having a generally U-shaped end for engaging the end of a respective one of said channel legs, said strap legs being disposed in parallel relation when the straps are in mounted conduit securing position; an abutment flange extending from each strap leg at an acute angle relative to its respective strap leg such that when said straps are mounted on said channel in opposed relation to a conduit said abutment flanges are interlocked with each other in side by side abutting relation for preventing outward separation of said strap legs; and means for securing said strap fastening elements to rigidly clamp said conduit between said strap curved portions and hold said abutting flanges in rigid engagement.

Claim 9

A clamping device for securing a conduit to a support channel having a pair of spaced legs interconnected by a web with the conduit being disposed transversely to said channel and substantially adjacent the web thereof, comprising a pair of straps each having a curved portion for engaging a side of said conduit, a leg extending from one side of said curved portion, and a fastening element at the opposite side thereof; said leg of each strap having a generally U-shaped end for engaging the end of a respective one of said channel legs, said strap legs being disposed in parallel relation when the straps are in mounted conduit securing position; an abutment flange extending from each strap leg at an acute angle relative to its respective strap leg such that when said straps are mounted on said channel in opposed relation to a conduit said abutment flanges are interlocked with each other in side by side abutting relation for preventing outward separation of said strap legs; and means for securing said strap fastening elements to rigidly clamp said conduit between said strap curved portions and hold said abutting flanges in rigid engagement.

Claim 10

The clamping device of claim 7 in which said abutment flanges each extend inwardly toward each other at an angle of about 15° relative to its respective support leg.

Claim 11

A clamping device for securing a conduit to a support channel having a pair of spaced legs interconnected by a web with the conduit being disposed transversely to said channel and substantially adjacent the web thereof, comprising a pair of straps each having a curved portion for engaging a side of said conduit, a leg extending from one side of said curved portion, and a fastening element at the opposite side thereof; said leg of each strap having a generally U-shaped end for engaging the end of a respective one of said channel legs; an abutment flange extending from each strap leg such that when said straps are mounted on said channel in opposed relation to a conduit said abutment flanges are positionable in side by side abutting and interlocked relation with each other for preventing outward separation of said strap legs; and said fastening element of each strap including a fastening flange extending from said curved portion, said fastening flange of each strap being formed with an aperture, a screw captively carried in the aperture of one of said straps for threadable engagement with the aperture of the other of said straps, and said aperture of each strap fastening flange being in slight off-centered relation to the strap such that when the straps are in mounted position said apertures are in skewed relation whereby tightening of said screw causes said strap curved portions to rapidly clamp a conduit interposed therebetween while maintaining said abutting flanges in rigid engagement.

Claim 12

A clamping device for securing a conduit to a support channel having a pair of spaced legs interconnected by a web with the conduit being disposed transversely to said channel and substantially adjacent the web thereof, comprising a pair of straps each having a curved portion for engaging a side of said conduit, a leg extending from one side of said curved portion, and a fastening element at the opposite side thereof; said leg of each strap having a generally U-shaped end for engaging the end of a respective one of said channel legs; an abutment flange extending from each strap leg such that when said straps are mounted on said channel in opposed relation to a conduit said abutment flanges are positionable in side by side abutting and interlocked relation with each other for preventing outward separation of said strap legs; and said fastening element of each strap including a fastening flange extending from said curved portion, said fastening flange of each strap being formed with an aperture, a screw captively carried in the aperture of one of said straps for threadable engagement with the aperture of the other of said straps, and said aperture of each strap fastening flange being in slight off-centered relation to the strap such that when the straps are in mounted position said apertures are in skewed relation whereby tightening of said screw causes said strap curved portions to rapidly clamp a conduit interposed therebetween while maintaining said abutting flanges in rigid engagement.
