Abstract: A barrier device for preventing articles stored in a glove compartment of a motor vehicle from falling or rolling out when the compartment door is opened. The barrier device assumes a vertical blocking position when the compartment door is moved to open position but may be collapsed to enable access to the interior of the compartment for removing or inserting articles from and into the compartment.

Abstract: Inclined chutes are filled with game balls of different colors or other visual characteristics. The underlying wall of each chute is formed of elastomeric material with openings therein of smaller diameters than the diameters of the balls so that the balls may roll down the chute and rest against each other and against a stop under the influence of gravity. Depressible plungers aligned with the openings may be selectively depressed to displace underlying balls through the openings from which they are guided to a display station.

Abstract: A shopping cart or the like having supporting wheels, one or more of which has a non-rotating detenting element rotatably engaged by rollers of elastomeric material carried by the wheel. Detenting formations on the element yieldably brake the wheel in different rotated positions to restrain free movement of the cart from a parked condition while permitting intentional movement of the cart with a minimum of resistance.

Abstract: A shopping cart or the like having supporting wheels, each having at least one annular cavity concentric with the axis of rotation of the respective wheel. The cavity is partly filled with weighted balls, and projections extend into the cavity for engagement with the balls to restrain free movement of the cart from a parked condition.

Abstract: A normally closed wafer thin switch, particularly intended for pilferage type burglar alarms, comprising a flat base plate of insulating material having an opening therein and a pair of leaf spring contacts attached to one peripheral portion of the plate and extending over the opening. Free ends of the contacts normally engage each other to complete a circuit. A raised tab on a first of the contacts overlies an opposite peripheral portion of the plate whereby, when an object is placed on or against the switch, the tab is depressed against the plate, causing opening of the switch.
