Claim 3
Dependent Claim
33 words
The collapsible stand of claim 1 wherein said hinges are so constructed as to permit limited movement of said posts with respect to said tie bar and feet when in the locked position.
Claim 4
Dependent Claim
26 words
The collapsible stand of claim 2 wherein said hinges include means urging said posts into the perpendicular position with respect to said tie bar and feet.
Claim 5
Dependent Claim
154 words
The collapsible stand of claim 3 wherein said tie bar and feet comprise tubular members and each of said hinges includes a channel member mounted on said post at right angles thereto, said channel having a pair of spaced flanges separated by a web for receiving an end portion of said tubular members between the flanges, the end portion of said tubular members containing a slot having an inner terminus adjacent said post and an outer terminus, said slot receiving a pin extending between the flanges of said channel for pivoting said tubular member in said channel, the spacing of the inner terminus of said slot from the end of said tubular member being such as to allow the end of the tubular member to clear the web of the channel during pivoting, and spring means for urging said pin into the outer terminus of said slot and said post into the perpendicular position.
Claim 6
Dependent Claim
70 words
The collapsible stand of claim 1 wherein said upright posts are comprised of a lower portion hinged to said tie bar and feet and an upper portion pivotally mounted on said lower portion for movement between a collapsed position and an erected position, the length of said upper portion being such as to permit said portion to lie along said lower portion when the post is in the collapsed position.
Claim 7
Dependent Claim
148 words
The collapsible stand of claim 5 wherein said lower portion of said upright posts comprises a channel member having a pair of spaced flanges separated by a web and said upper portion has an end part insertable between the flanges of said lower portion, the end part of said upper portion containing a slot having a first terminus adjacent the end of said upper portion and a second terminus, said slot receiving a pin extending between the flanges of said channel for pivoting said upper member in said channel, the spacing of the first terminus of said slot from the end of said upper portion being such as to allow the end of the upper portion to clear the web of the channel during pivoting, said pin being slidable into the second terminus of said slot to retain the upper portion of the post in the upright position.
Claim 8
Dependent Claim
28 words
The collapsible stand of claim 1 wherein the length of said tie bar is greater than the length of said elongated feet to facilitate collapsing of said stand.
