Total Claims: 6
Claim 1
Independent Claim
191 words
In an arrangement of a first member and a second member in which the first member is connected to the second member for generally pivotal movement between a raised, extended position and a downwardly extending collapsed position, an improved connecting device comprising: a connector member; means for securing the connector member to the second member; said connector member having a pair of slots formed therein, said slots being angularly spaced and meeting at a juncture, one of said slots being longer than the other of said slots, said connector being oriented so that one of said slots extends generally downwardly from the juncture; a pair of pins attached to said first member, said pins extending through the slots in the connector member; said pins being spaced by an amount which is less than the length of said one of said slots whereby when said first member is disposed at an angle with respect to said second member the pins will be in alignment with said one of said slots and both of said pins may be advanced downwardly into said one slot to lock the first member in said extended position.
Claim 2
Dependent Claim

In an arrangement of a first member and a second member in which the first member is connected to the second member for generally pivotal movement between a raised, extended position and a downwardly extending collapsed position, an improved connecting device comprising: a connector member; means for securing the connector member to the second member; said connector member having a pair of slots formed therein, said slots being angularly spaced and meeting at a juncture, one of said slots being longer than the other of said slots, said connector being oriented so that one of said slots extends generally downwardly from the juncture; a pair of pins attached to said first member, said pins extending through the slots in the connector member; said pins being spaced by an amount which is less than the length of said one of said slots whereby when said first member is disposed at an angle with respect to said second member the pins will be in alignment with said one of said slots and both of said pins may be advanced downwardly into said one slot to lock the first member in said extended position.
Claim 3
Dependent Claim
57 words
A device as defined in claim 1 further comprising: said pair of slots defining an L-shaped configuration; said pins being attached to the first member by means comprising an L-shaped plate having a pair of legs; said pins being mounted to one of said legs; and said first member being mounted to the other of said legs.
Claim 4
Dependent Claim
38 words
A device as defined in claim 2 further comprising: said connector member being substantially L-shaped and having said one slot formed in one leg of the connector member, said leg having means for attachment to said second member.
Claim 5
Dependent Claim
81 words
A device as defined in claim 3 wherein said second member comprises a vertically extending standard and wherein said means for attaching the L-shaped connector member to said standard comprises: said leg of said L-shaped connector member having a longitudinally extending flange receptive in a channel formed in said standard, said flange being movable lengthwise along the standard to vary its position on the standard; and means for locking the flange to the standard in a selected position along the standard.
Claim 6
Dependent Claim
39 words
A device as defined in claim 4 further comprising: means for varying the angular attitude of the L-shaped connector member with respect to the standard within a predetermined range and for locking the L-shaped member in said selected attitude.
