Abstract
A locking mechanism for covering the open end of a sign stand upright extrusion and for releasably locking a roll-up sign in place in the upright. A cap member covers the end of the extrusion. The cap member has a slanted surface for ease of entry of the sign into the upright extrusion, and a locking pin member for releasably locking said sign in place. The locking pin is adapted to be manually manipulated and has a pointed leading end for mating with an opening or recess in the sign cross brace member. A stop is also provided in the upright extrusion for holding the sign at the required height.

A sign retention device for releasably securing a sign to a sign stand, the sign having an elongated vertical cross-brace with at least one aperture therein and the sign stand having a base and an upright member with an upper end, the sign retention device comprising:
- a cap member, said cap member having an internal cavity,
- means for affixing said cap member to the upper end of the upright member, said internal cavity adapted to be positioned over the upper end of the upright member;
- said cap member having a channel therein for allowing the vertical cross-brace to pass through in a vertical downward direction substantially parallel to said upright member and be prevented from removal therefrom except in a vertical upward direction,
- ramp means on said cap member adjacent said channel for directing said vertical cross-brace into said channel, and
- a biased locking member for mating with an aperture in said vertical cross-brace and securing the cross-brace in place in said cap member.
A system for releasably securing a sign to a sign stand, comprising:
- a sign stand having a base and an upright member with an upper end,
- a sign having a vertically oriented elongated cross-brace with at least one aperture therein,
- a cap member having a central cavity therein, said cap member positioned over said upper end of said upright member,
- means for affixing said cap member to said upright member,
- said cap member having an aperture therein for holding said vertical cross-brace,
- biased locking means for mating with said aperture in said vertical cross-brace and thereby securing said sign to said sign stand.
