Abstract

Abstract A stabilizer strut extending transversely between grid members in a supporting grid system and the like. The strut includes a pair of leg portions disposed at right angles to one another with each end of the strut including a pair of aligned slot portions for engagement with an underlying grid member. Each grid member includes an upstanding web means surmounted by a bead means wherein the latter receives the pair of aligned slot portions which are open at the non-adjacent, lateral edges of the strut leg portions. One slot on each end of the strut corresponding to one another include a locking projection extending inwardly from the side of the slot at a point adjacent to the open end thereof at the lateral edge of the strut. The locking projection is adapted to extend beneath the bead means of a grid member to restrain the strut against vertical uplift while the other slot at each end of the strut is of a width adapted to be received over the bead means so as to be in sufficient lateral engagement therewith to provide stabilized lateral support between the grid members.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 227 words
In combination with a pair of spaced grid members disposed in a substantially parallel manner with respect to one another, a stabilizer strut for lateral connection between said grid members which form a supporting grid system and the like wherein each grid member includes an upstanding web means surmounted by a bead means extending longitudinally along the upper longitudinal edge of said web means and laterally outwardly of at least one side of said web means, said stabilizer strut comprising: an elongated body extending between a pair of grid members, said body having a pair of angularly related leg portions at each of its ends in locking engagement with a grid member, each of said pair of leg portions including a pair of aligned slot portions extending inwardly from the non-adjacent, lateral edges of said leg portions wherein only one of said aligned slot portions on each end of said body which correspond to one another includes a locking projection extending beneath said bead means to restrain said strut against vertical uplift with respect to said grid members and the other of said aligned slot portions is of a width so as to be received over said bead means in sufficient lateral engagement therewith to provide stabilized lateral support between a pair of grid members and to maintain said locking projection in place beneath said bead means.
Claim 2
Dependent Claim 227 words
In combination with a pair of spaced grid members disposed in a substantially parallel manner with respect to one another, a stabilizer strut for lateral connection between said grid members which form a supporting grid system and the like wherein each grid member includes an upstanding web means surmounted by a bead means extending longitudinally along the upper longitudinal edge of said web means and laterally outwardly of at least one side of said web means, said stabilizer strut comprising: an elongated body extending between a pair of grid members, said body having a pair of angularly related leg portions at each of its ends in locking engagement with a grid member, each of said pair of leg portions including a pair of aligned slot portions extending inwardly from the non-adjacent, lateral edges of said leg portions wherein only one of said aligned slot portions on each end of said body which correspond to one another includes a locking projection extending beneath said bead means to restrain said strut against vertical uplift with respect to said grid members and the other of said aligned slot portions is of a width so as to be received over said bead means in sufficient lateral engagement therewith to provide stabilized lateral support between a pair of grid members and to maintain said locking projection in place beneath said bead means.
Claim 3
Dependent Claim 43 words
The combination as set forth in claim 1 wherein each said pair of aligned slot portions of said strut are substantially perpendicular to the longitudinal axis thereof whereby said strut is assembled in a substantially perpendicular manner to each of said grid members.
Claim 4
Dependent Claim 26 words
The combination as set forth in claim 1 wherein said locking projection comprises a tab portion extending into said slot to extend beneath said bead means.
Claim 5
Dependent Claim 259 words
In combination in a supporting grid system and the like wherein a grid member includes an upstanding web means surmounted by a bead means extending longitudinally along the upper longitudinal edge of said web means and laterally outwardly of at least one side of said web means, a stabilizer strut for lateral connection between grid members, said stabilizer strut comprising; an elongated body adapted to extend between a pair of grid members, said body having a pair of angularly related leg portions at each of its ends adapted for locking engagement with a grid member, each of said pair of leg portions including a pair of aligned slot portions extending inwardly from the non-adjacent, lateral edges of said leg portions wherein one of said aligned slot portions includes a locking projection adapted to extend beneath said bead means to restrain said strut against vertical uplift with respect to said grid members and the other of said aligned slot portions is of a width adapted to be received over said bead means so as to be in sufficient lateral engagement with said bead means to provide stabilized lateral support between a pair of grid members and to maintain said locking projection in place beneath said bead means, and a pair of spaced grid members disposed in a substantially parallel manner with respect to one another wherein each said pair of aligned slot portions of said strut are substantially perpendicular to the longitudinal axis thereof whereby said strut is assembled in a substantially perpendicular manner to each of said grid members.
Claim 6
Dependent Claim 259 words
In combination in a supporting grid system and the like wherein a grid member includes an upstanding web means surmounted by a bead means extending longitudinally along the upper longitudinal edge of said web means and laterally outwardly of at least one side of said web means, a stabilizer strut for lateral connection between grid members, said stabilizer strut comprising; an elongated body adapted to extend between a pair of grid members, said body having a pair of angularly related leg portions at each of its ends adapted for locking engagement with a grid member, each of said pair of leg portions including a pair of aligned slot portions extending inwardly from the non-adjacent, lateral edges of said leg portions wherein one of said aligned slot portions includes a locking projection adapted to extend beneath said bead means to restrain said strut against vertical uplift with respect to said grid members and the other of said aligned slot portions is of a width adapted to be received over said bead means so as to be in sufficient lateral engagement with said bead means to provide stabilized lateral support between a pair of grid members and to maintain said locking projection in place beneath said bead means, and a pair of spaced grid members disposed in a substantially parallel manner with respect to one another wherein each said pair of aligned slot portions of said strut are substantially perpendicular to the longitudinal axis thereof whereby said strut is assembled in a substantially perpendicular manner to each of said grid members.
Claim 7
Dependent Claim 53 words
A stabilizer strut as set forth in claim 4 wherein the side of said slot opposite said locking projection includes a shouldered portion so that upon reception of said slot over said bead means said shouldered portion abuts said bead means to align said locking projection with the underside of said bead means.
Claim 8
