Abstract
Abstract A pair of self-supporting exhibit frames formed of a plurality of pairs of crossed rods are constructed so as to be moved between a collapsed position at which the rods are disposed in a compact bundle of side-by-side rods and an erected position at which each exhibit frame includes a lateral upstanding side defined by at least two crossed rods disposed in a generally X-shaped pattern, the exhibit frames being positioned with their lateral upstanding sides immediately adjacent each other and with the X-shaped rods aligned, and at least one bracket spanning the lateral upstanding sides, the bracket including at least two slots and preferably four slots disposed with one pair of slots along each of two side edges of the bracket, and the slots being sized to snugly frictionally grippingly engage the X-shaped rod to thereby maintain the exhibit frames locked together in adjacent upstanding relationship.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
173 words
The combination of a pair of collapsible and expandable structures and a bracket for releasably securing the pair of structures together comprising a plurality of pairs of crossed rods defining each of said pair of structures, means for interconnecting said plurality of pairs of crossed rods of each structure for effecting movement thereof between a collapsed position at which said rods are disposed in a compact bundle of side-by-side rods and an erected expanded position a which each structure includes a lateral upstanding side defined by at least two crossed rods disposed in a generally X-shaped pattern, said structures being positioned with their lateral upstanding sides immediately adjacent each other, said bracket spanning said lateral upstanding sides, said bracket including first and second means for slidingly engaging, releasably securing and slidingly disengaging said bracket to one rod of each of said two crossed rods of each lateral side, respectively, whereby said bracket can be moved toward and away from the interconnecting means to respectively engage and disengage the bracket relative to the rods.
Claim 2
Dependent Claim
173 words
The combination of a pair of collapsible and expandable structures and a bracket for releasably securing the pair of structures together comprising a plurality of pairs of crossed rods defining each of said pair of structures, means for interconnecting said plurality of pairs of crossed rods of each structure for effecting movement thereof between a collapsed position at which said rods are disposed in a compact bundle of side-by-side rods and an erected expanded position a which each structure includes a lateral upstanding side defined by at least two crossed rods disposed in a generally X-shaped pattern, said structures being positioned with their lateral upstanding sides immediately adjacent each other, said bracket spanning said lateral upstanding sides, said bracket including first and second means for slidingly engaging, releasably securing and slidingly disengaging said bracket to one rod of each of said two crossed rods of each lateral side, respectively, whereby said bracket can be moved toward and away from the interconnecting means to respectively engage and disengage the bracket relative to the rods.
Claim 3
Dependent Claim
25 words
The combination as defined in claim 1 wherein said first and second means is each a slot contoured to snugly matingly engage its associated rod.
Claim 4
Dependent Claim
45 words
The combination as defined in claim 1 wherein said bracket is a generally plate-like body defined by a periphery, said first and second means is each a slot contoured to snugly matingly engage its associated rod, and said slots open outwardly relative to said periphery.
Claim 5
Dependent Claim
51 words
The combination as defined in claim 1 wherein said bracket is a generally plate-like body defined by a periphery, said first and second means is each a slot contoured to snugly matingly engage its associated rod, and said slots open outwardly relative to said periphery and in opposite directions relative thereto.
Claim 6
Dependent Claim
48 words
The combination as defined in claim 1 wherein said bracket is a generally plate-like body defined by a periphery, said first and second means is a pair of slots contoured to snugly matingly engage its associated pair of rods, an said slots open outwardly relative to said periphery.
Claim 7
Dependent Claim
67 words
The combination as defined in claim 1 wherein said bracket is a generally plate-like body defined by a periphery, said first and second means is a pair of slots contoured to snugly matingly engage its associated pair of rods, and said slots open outwardly relative to said periphery with one pair of slots opening in one direction and another pair of slots opening in an opposite direction.
Claim 8
Dependent Claim
174 words
The combination of a pair of portable collapsible and expandable exhibits and a bracket for releasably securing the pair of exhibits together comprising a plurality of pairs of crossed rods defining each of said pair of exhibits, means for interconnecting a plurality of pairs of crossed rods of each exhibit for effecting movement thereof between a collapsed position at which said rods are disposed in a compact bundle of side-by-side rods and an erected expanded position at which each exhibit includes a lateral upstanding side defined by at least two crossed rods disposed in a generally X-shaped pattern, said exhibits being positioned with their lateral upstanding sides immediately adjacent each other, said bracket spanning said lateral upstanding sides, said bracket including first and second means for slidingly engaging, releasably securing and slidingly disengaging said bracket to one rod of each of said two crossed rods of each lateral side, respectively, whereby said bracket can be moved toward and away from the interconnecting means to respectively engage and disengage the bracket relative to the rods.
Claim 9
Dependent Claim
174 words
The combination of a pair of portable collapsible and expandable exhibits and a bracket for releasably securing the pair of exhibits together comprising a plurality of pairs of crossed rods defining each of said pair of exhibits, means for interconnecting a plurality of pairs of crossed rods of each exhibit for effecting movement thereof between a collapsed position at which said rods are disposed in a compact bundle of side-by-side rods and an erected expanded position at which each exhibit includes a lateral upstanding side defined by at least two crossed rods disposed in a generally X-shaped pattern, said exhibits being positioned with their lateral upstanding sides immediately adjacent each other, said bracket spanning said lateral upstanding sides, said bracket including first and second means for slidingly engaging, releasably securing and slidingly disengaging said bracket to one rod of each of said two crossed rods of each lateral side, respectively, whereby said bracket can be moved toward and away from the interconnecting means to respectively engage and disengage the bracket relative to the rods.
Claim 10
Dependent Claim
19 words
The combination as defined in claim 7 wherein said pair of exhibits are disposed in a generally common plane.
Claim 11
Dependent Claim
32 words
The combination as defined in claim 7 wherein said first and second means of said bracket are secured to one rod of each of said two crossed rods of each lateral side.
