In combination, a chain and a hold down anchor for the chain and comprising a substantially L-shaped metal bar one arm of which is adapted to be positioned in a hole in a floor, a support block secured to the second arm of said metal bar and extending upwardly therefrom, the upper end of said support block being bifurcated and having a surface inclined upwardly and away from said metal bar first arm, said chain having one link engaging said metal bar and having a link bearing on said support block surface for load transmittal to said metal bar and support block, the other end of said chain extending to another area for attachment to a load.
Claim 2
Dependent Claim
117 words
In combination, a chain and a hold down anchor for the chain and comprising a substantially L-shaped metal bar one arm of which is adapted to be positioned in a hole in a floor, a support block secured to the second arm of said metal bar and extending upwardly therefrom, the upper end of said support block being bifurcated and having a surface inclined upwardly and away from said metal bar first arm, said chain having one link engaging said metal bar and having a link bearing on said support block surface for load transmittal to said metal bar and support block, the other end of said chain extending to another area for attachment to a load.
Claim 3
Dependent Claim
43 words
In a combination, as in claim 1, a reenforcing means secured to and dependent from a second arm of said metal bar, which reenforcing means engages and supports said support block and which reenforcing means is adapted to seat on a support surface.
Claim 4
Dependent Claim
163 words
A hold down anchor for engaging a support for a chain or the like comprising a metal rod including two straight arm sections forming an angle of about 90°, one of said arm sections being adapted to be received in a socket hole in the floor or support, a reenforcing plate means secured to said second arm section at spaced portions thereof and dependent therefrom to rest on the floor or support when in use, a vertically extending support block having bifurcated top and bottom portions and with the bottom portion positioned over said second arm section and extending down to and engaging and supported by said plate means and the top portion of said support block being recessed to engage a link of a chain another portion of which engages said metal rod whereby the chain can extend from said support block to a load but with the chain being adapted to be anchored by said one arm section of said rod.
Claim 5
Dependent Claim
163 words
A hold down anchor for engaging a support for a chain or the like comprising a metal rod including two straight arm sections forming an angle of about 90°, one of said arm sections being adapted to be received in a socket hole in the floor or support, a reenforcing plate means secured to said second arm section at spaced portions thereof and dependent therefrom to rest on the floor or support when in use, a vertically extending support block having bifurcated top and bottom portions and with the bottom portion positioned over said second arm section and extending down to and engaging and supported by said plate means and the top portion of said support block being recessed to engage a link of a chain another portion of which engages said metal rod whereby the chain can extend from said support block to a load but with the chain being adapted to be anchored by said one arm section of said rod.
Claim 6
Dependent Claim
48 words
A hold down anchor as in claim 3 where said recess in said support block has a base surface extending upwardly and outwardly from said one arm section and where a said chain link fits between the spaced ends of the bifurcated top portion of said support block.
