Abstract

Abstract An extension assembly adapted to be attached to a conventional work bench to permit elongated and bulky work pieces to be supported thereon. The extension assembly includes a horizontal member having a portion to be supported on the work bench and a vertical upright member, pivotally connected to the horizontal member, to support another portion. One or a plurality of extension assemblies may be selectably attachable to the work bench for effective use.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 262 words
An extension assembly for attachment to a work bench to accommodate and support and elongated object comprising at least one horizontal member having a first portion adapted to be releasably attached to a horizontal table of the work bench and having an auxiliary object support surface spaced from the horizontal table, at least one substantially upright member operatively connected to said at least one horizontal member and having a bottom portion adapted to contact a support surface, said upright member acting to vertically support another portion of said at least one horizontal member, said first portion of said at least one horizontal member lying in sandwiched relationship to the horizontal table of the work bench while being supported thereby, releasable attachment means coupled to said at least one horizontal member securing said first portion to the work table, said first portion being disposed in sandwiched relationship above the horizontal table, said releasable attachment means including a member having a lower surface in bearing contact with the upper surface of the work bench and an upper surface forming an object surface above the surface of the horizontal table of the work bench and the at least one horizontal member, said member having at least one downwardly extending pin in said sandwiched relationship for insertion into a vertical hole in the horizontal table of the work bench at least through said horizontal member for securing said first portion thereto, and said horizontal member being vertically adjustable to selectively align said auxiliary support surface with said upper surface of said member along a desired plane.
Claim 2
Dependent Claim 262 words
An extension assembly for attachment to a work bench to accommodate and support and elongated object comprising at least one horizontal member having a first portion adapted to be releasably attached to a horizontal table of the work bench and having an auxiliary object support surface spaced from the horizontal table, at least one substantially upright member operatively connected to said at least one horizontal member and having a bottom portion adapted to contact a support surface, said upright member acting to vertically support another portion of said at least one horizontal member, said first portion of said at least one horizontal member lying in sandwiched relationship to the horizontal table of the work bench while being supported thereby, releasable attachment means coupled to said at least one horizontal member securing said first portion to the work table, said first portion being disposed in sandwiched relationship above the horizontal table, said releasable attachment means including a member having a lower surface in bearing contact with the upper surface of the work bench and an upper surface forming an object surface above the surface of the horizontal table of the work bench and the at least one horizontal member, said member having at least one downwardly extending pin in said sandwiched relationship for insertion into a vertical hole in the horizontal table of the work bench at least through said horizontal member for securing said first portion thereto, and said horizontal member being vertically adjustable to selectively align said auxiliary support surface with said upper surface of said member along a desired plane.
Claim 3
Dependent Claim 218 words
An extension assembly for attachment to a work bench to accommodate and support an elongated object comprising: at least one horizontal member having a first portion adapted to be releasably attached to a horizontal table of the work bench; at least one substantially upright member operatively connected to said at least one horizontal member and having a bottom portion adapted to contact a support surface; said upright member acting to vertically support amother portion of said at least one horizontal member; said first portion of said at least one horizontal member lying in sandwiched relationship beneath the horizontal table of the work bench while being supported thereby and having a surface in contact with the underside of the horizontal table; releasable attachment means coupled to said at least one horizontal member securing said first portion to the work table; said releasable attachment means including a member having an upper surface in contact with the underside of said at least one horizontal member; said releasable attachment means further having at least one expandible member extending upward through said member for frictional engagement with a hole in the horizontal table of the work bench; and said horizontal member being vertically adjustable to selectively align said auxiliary support surface with the upper surface of the horizontal table along a desired plane.
Claim 4
Dependent Claim 218 words
An extension assembly for attachment to a work bench to accommodate and support an elongated object comprising: at least one horizontal member having a first portion adapted to be releasably attached to a horizontal table of the work bench; at least one substantially upright member operatively connected to said at least one horizontal member and having a bottom portion adapted to contact a support surface; said upright member acting to vertically support amother portion of said at least one horizontal member; said first portion of said at least one horizontal member lying in sandwiched relationship beneath the horizontal table of the work bench while being supported thereby and having a surface in contact with the underside of the horizontal table; releasable attachment means coupled to said at least one horizontal member securing said first portion to the work table; said releasable attachment means including a member having an upper surface in contact with the underside of said at least one horizontal member; said releasable attachment means further having at least one expandible member extending upward through said member for frictional engagement with a hole in the horizontal table of the work bench; and said horizontal member being vertically adjustable to selectively align said auxiliary support surface with the upper surface of the horizontal table along a desired plane.
Claim 5
Dependent Claim 41 words
The extension assembly according to claim 1 or 2 wherein said upright member is pivotally connected to said at least one horizontal member to permit said upright member and said at least one horizontal member to be substantially folded for portability.
Claim 6
Dependent Claim 48 words
The extension assembly according to claim 1 or 2 wherein said at least one horizontal member is a plurality of members adapted to be releasably supported on the horizontal table of the work bench, each of said plurality of horizontal members being connected to a respective upright member.
Claim 7
Dependent Claim 53 words
The extension assembly according to claim 1 wherein said member of said releasable attachment means further includes a second lower surface lying in spaced relationship to the upper surface of the work bench in said sandwiched relationship, said pin extending downward into said hold of the horizontal table from said second lower surface.
