Releasable support rod

Claim 2

A releasable support rod structure comprising: plate means disposed for securement in stationary relation to a wall structure and containing an exposed substantially flat vertically oriented face, yieldable load-bearing means separate from and movably engageable with said flat face and having an upper portion abutting said flat face and a depending rod holding portion disposed in below said upper portion opposed facing relation to said flat face and selectively limitedly movably displaceable operatively toward and away from said flat face for holding an independent and separate rod engageably releasably insertable thereat, said yieldable load-bearing means including means for adjusting the tautness thereof for presetting the load-bearing capacity of said yieldable means said rod holding portion being relatively U-shaped in cross-section and having the corresponding open portion of the U-shaped portion thereof disposed in opposed facing relation to said flat face and being selectively limitedly movably displaceable with respect to said flat face to disengage and release said rod under the weight of a downward overload relative to the selective load-bearing adjustment of said yieldable load-bearing means placed directly on said rod and transmitted through said rod to said yieldable load-bearing means.

Claim 3

Structure according to to claim 1 wherein said plate means includes a relatively L-shaped member having a side wall section and a rear wall section and adapted for securement along the remote face of said side wall section of the L-shaped member substantially vertically in stationary relation to a vertical wall structure, said exposed flat face constituting the face on the side of said rear wall section facing the face on the side of the side wall section opposite from that containing said side wall remote face.

Claim 4

Structure according to claim 1 wherein the yieldable load-bearing means includes a leaf spring having an upper flat portion in abutting movable engagement relation with said plate means.

Claim 5

Structure according to claim 1 wherein a selectively adjustable spring member is provided for adjusting the tautness of the yieldable load-bearing means for pre-setting the load-bearing capacity thereof.

Claim 6

Structure according to claim 4 wherein an adjustable bolt and nut connection means is provided for operatively movably engageably interconnecting said yieldable load-bearing means with said plate means and the spring member abuts and is maintained under predetermined tension in engagement with the yieldable load-bearing means remote from said plate means by said bolt and nut means.

Claim 7

Structure according to claim 1 wherein said yieldable load-bearing means includes a manually manipulatable portion extending from said U-shaped portion to permit limited manual displacement of said U-shaped portion.

Claim 8

A releasable support rod structure comprising: plate means including a relatively L-shaped member having a side wall section and a rear wall section and adapted for securement along the remote face of said side wall section substantially vertically in stationary relation to a vertical wall structure, and containing an exposed substantially flat planar engageable face on the side of said rear wall section facing the adjacent face on the side of the side wall section opposite from that containing said side wall remote face, selectively adjustably yieldable load-bearing means separate from and movably engageable with said plate means, and including a leaf spring having an upper flat portion in abutting movable engagement relation with said flat face, a depending intermediate rod holding portion disposed below said upper portion in opposed facing relation to said flat face and selectively limitedly movably displaceable operatively toward and away from said flat face for holding an independent and separate rod engageably releaseably insertable thereat, and a lower manually manipulatable portion extending from said rod holding portion to permit limited manual displacement of said rod holding portion, and a cooperating selectively adjustable bolt and nut connection means and coil spring for operatively movably engageably interconnecting the leaf spring with the plate means and for adjusting the tautness of the leaf spring for pre-setting the load-bearing capacity thereof, said spring being loaded operatively between the leaf spring upper flat portion and the bolt and nut connection means in abutting engagement relation with the leaf spring and remote from said plate means and maintained under predetermined tension by said bolt and nut connection means, said rod holding portion being relatively U-shaped in cross-section and having the corresponding open portion of the U-shaped portion thereof disposed in opposed facing relation to said flat face and being selectively limitedly movably displaceable with respect to said flat face to disengage and release said rod under the weight of a downward overload relative to the selective load-bearing adjustment of said leaf spring placed directly on said rod and transmitted through said rod to said leaf spring.

Claim 9

A releasable support rod structure comprising: plate means including a relatively L-shaped member having a side wall section and a rear wall section and adapted for securement along the remote face of said side wall section substantially vertically in stationary relation to a vertical wall structure, and containing an exposed substantially flat planar engageable face on the side of said rear wall section facing the adjacent face on the side of the side wall section opposite from that containing said side wall remote face, selectively adjustably yieldable load-bearing means separate from and movably engageable with said plate means, and including a leaf spring having an upper flat portion in abutting movable engagement relation with said flat face, a depending intermediate rod holding portion disposed below said upper portion in opposed facing relation to said flat face and selectively limitedly movably displaceable operatively toward and away from said flat face for holding an independent and separate rod engageably releaseably insertable thereat, and a lower manually manipulatable portion extending from said rod holding portion to permit limited manual displacement of said rod holding portion, and a cooperating selectively adjustable bolt and nut connection means and coil spring for operatively movably engageably interconnecting the leaf spring with the plate means and for adjusting the tautness of the leaf spring for pre-setting the load-bearing capacity thereof, said spring being loaded operatively between the leaf spring upper flat portion and the bolt and nut connection means in abutting engagement relation with the leaf spring and remote from said plate means and maintained under predetermined tension by said bolt and nut connection means, said rod holding portion being relatively U-shaped in cross-section and having the corresponding open portion of the U-shaped portion thereof disposed in opposed facing relation to said flat face and being selectively limitedly movably displaceable with respect to said flat face to disengage and release said rod under the weight of a downward overload relative to the selective load-bearing adjustment of said leaf spring placed directly on said rod and transmitted through said rod to said leaf spring.
