Abstract: A portable voting booth for a user to erect at a voting place when needed and disassemble thereafter for transportation and storage includes a base portion and a plurality of legs for assemble onto the base portion. The base portion defines a plurality of leg-receiving bores for receiving hollow tubular end portions of the plurality of legs. The base portion also includes leg-gripping components within the bores for gripping the tubular end portions in order to restrain the legs from falling out of the leg-receiving bores under influence of gravity. The leg-gripping components of one embodiment include four resiliently deformable, axially extending fingers within each of four leg-receiving bores, the fingers resiliently deforming so that they fit axially into the tubular end portions to bear radially outward against the inwardly facing inner walls of the tubular end portions for leg-restraining purposes.

Abstract: A security device for use on shopping carts comprises an extra wheel adapted to be installed on a cart such that it normally travels along the ground at location spaced behind the front wheels, and a locking assembly for locking the extra wheel in a turn-inducing orientation when actuated by someone pushing the cart over a raised barrier. The extra wheel is mounted on the cart by a telescopic mounting assembly comprising first and second telescoping cylinders. The first cylinder is adapted to be mounted on the cart in a vertical orientation at a position spaced behind the front wheels, and the extra wheel is mounted at the lower end of the second cylinder which is telescopically engaged in the first cylinder.
