Abstract
Abstract A display stand for merchandise such as clothing or the like includes a base supporting a telescopic stand structure formed from a pair of telescopic tubular members. The upper tubular member has an inner end portion including an angled cam surface thereon which receives a cam member between the cam surface and an adjacent inner wall of the lower or outer tubular member. A threaded rod is secured to the cam and extends through the upper tubular member to an upper threaded free end on which a nut is threadably received. Rotation of the nut causes the cam to wedge between the inclined surface of the inner tubular member and the inner adjacent surface of the outer tubular member, to lock the telescopic members in position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
208 words
A display stand comprising first and second telescopically engaged elongated stand elements, said first element having an inner end received within said second element and a remote outer end; said first end having an inclined face located at an angle to the longitudinal axis of said first element; an elongated rod extending through said first element from a first end adjacent the first end of said first stand element to a second end extending beyond the second end of the first stand element; a cam member secured to the first end of the rod in position to engage the inclined face of said first stand element; said second end of the rod being threaded, and a nut threadedly engaged with said rod and bearing against the second end of said first stand element whereby rotation of the nut in a first direction moves said cam against said inclined face and wedges it between said inside face and the inner surface of said second stand element to lock said elements together; and rotation of said nut in an opposite direction moves the cam away from said inclined face and the inner surface of said second stand element to permit said stand elements to telescope with respect to one another.
Claim 2
Dependent Claim
208 words
A display stand comprising first and second telescopically engaged elongated stand elements, said first element having an inner end received within said second element and a remote outer end; said first end having an inclined face located at an angle to the longitudinal axis of said first element; an elongated rod extending through said first element from a first end adjacent the first end of said first stand element to a second end extending beyond the second end of the first stand element; a cam member secured to the first end of the rod in position to engage the inclined face of said first stand element; said second end of the rod being threaded, and a nut threadedly engaged with said rod and bearing against the second end of said first stand element whereby rotation of the nut in a first direction moves said cam against said inclined face and wedges it between said inside face and the inner surface of said second stand element to lock said elements together; and rotation of said nut in an opposite direction moves the cam away from said inclined face and the inner surface of said second stand element to permit said stand elements to telescope with respect to one another.
Claim 3
Dependent Claim
30 words
A display stand as defined in claim 1 including cam blocks secured to said first end of the first stand element adjacent said inclined face thereof for engaging said cam.
Claim 4
Dependent Claim
28 words
A display stand as defined in claims 1 or 2 wherein said cam is a generally cylindrical member secured to said rod to extend transversely of the rod.
Claim 5
Dependent Claim
32 words
A display stand as defined in claim 3 wherein said second stand element includes a support base and said first stand element includes a support arm secured thereto adjacent said second end.
Claim 6
Dependent Claim
234 words
A display stand comprising a first elongated hollow support tube having a generally rectangular cross-section, a first end including a support base and an open second upper end; a second elongated hollow support tube having a slightly smaller rectangular cross-section than said first tube to be received in the open upper end of said first tube; said second tube having a first open end received in said first tube and a second closed end having an opening formed therein; said first end of said second tube including an inclined cam surface extending at an angle to the longitudinal axis of the tubes and towards one of the inner side walls of said first tube; an elongated rod extending through said second tube and the opening therein and including a first end located adjacent the first end of the second tube and a second threaded upper end located above the second end of said second tube; a nut threadedly engaged with said threaded upper end of the rod; and a cam secured to said first end of the rod in engagement with said cam surface whereby rotation of said nut in a first direction wedges the cam between said cam surface and said one inner side wall to lock said tubes together; and rotation of said nut in an opposite direction releases such engagement to permit said tubes to telescope with respect to each other.
Claim 7
Dependent Claim
234 words
A display stand comprising a first elongated hollow support tube having a generally rectangular cross-section, a first end including a support base and an open second upper end; a second elongated hollow support tube having a slightly smaller rectangular cross-section than said first tube to be received in the open upper end of said first tube; said second tube having a first open end received in said first tube and a second closed end having an opening formed therein; said first end of said second tube including an inclined cam surface extending at an angle to the longitudinal axis of the tubes and towards one of the inner side walls of said first tube; an elongated rod extending through said second tube and the opening therein and including a first end located adjacent the first end of the second tube and a second threaded upper end located above the second end of said second tube; a nut threadedly engaged with said threaded upper end of the rod; and a cam secured to said first end of the rod in engagement with said cam surface whereby rotation of said nut in a first direction wedges the cam between said cam surface and said one inner side wall to lock said tubes together; and rotation of said nut in an opposite direction releases such engagement to permit said tubes to telescope with respect to each other.
Claim 8
Dependent Claim
25 words
A display stand as defined in claim 5 including cam blocks secured to said first end of said second tube defining said inclined cam surface.
Claim 9
Dependent Claim
29 words
A display stand as defined in claim 6 wherein said first end of said second tube has parallel free edges inclined at the same angle as said cam blocks.
Claim 10
Dependent Claim
26 words
A display stand as defined in claim 7 wherein said cam is a generally cylindrical member secured to said rod to extend transversely of the rod.
