Abstract:
A device and method for forming an indented female connector where the dimension of the indented female connector provides for removing a male molding component without damaging a set of internal ribs formed inside the female connector. A structure comprising an indented female blow-molded connector having a first wall having a top surface and a thickness, with the first wall surrounding an opening. At least one inner wall extends substantially perpendicular to the first wall and borders the opening. At least one rib is formed in the inner wall. A bottom wall is joined to the inner wall and the distance from the rib to the top surface is greater than the thickness of the first wall. The structure further comprising a male connector having a contact edge that, when positioned inside the indented female blow-molded connector, engage the at least one rib, such that the male connector and indented female blow-molded connector are releaseably joinable with one another. Structures can be made that use the indented female blow molded connectors and male connectors including braced stools having three or four legs.

US Patent:
7540682, Jun 2, 2009
Filed:
May 8, 2008
Appl. No.:
12/117644
Inventors:

Assignee:
Off the Wall Products LLC - Salt Lake City UT
International Classification:
E01F 9/012
US Classification:
404 6, 404 9, 116 63 P, 4060601
Abstract:
A control barrier includes a barrier wall having a front face and an opposing back face each extending between a top end and an opposing bottom end, a first recess being formed on the front face at the bottom end of the barrier wall. A first slot extends through the barrier wall from the first recess to the back face. An elongated first leg is coupled with the barrier wall so that the first leg can selectively rotate and can selectively slide. A first foot is mounted on the elongated first leg, the first foot being selectively movable between a first position wherein the first foot is at least partially disposed within the recess of the barrier wall and a second position wherein the first foot is rotated a least 45 relative to the first position and is removably positioned within the slot extending through the barrier wall.

US Classification:
403282, 403242, 403244, 1822281
Abstract:
A first plastic component and a second plastic component are joined together by an expansive joint system on the first plastic component and a driving joint system on the second plastic component. The expansive joint system has two expansive units while the driving joint system has corresponding driving units. When the driving units simultaneously expand the respective expansive units to a predetermined point, the expansive units contract to their original position and securely lock onto portions of the second plastic component.
