20090120736 | AUTOMATIC BRAKING FOR A MANUALLY CONTROLLED WHEELED CART - The present invention is a manually controlled and propelled wheeled vehicle whose wheels are locked or held in place via a braking mechanism. This invention includes a proximity sensing mechanism that determines when an operator is sufficiently in control of the wheeled vehicle. Upon an operator presence being determined, the proximity sensor calls for the release of the wheel locks and or braking mechanisms. Once the operator is no longer in the proper position, the wheel locks or brakes re-engage. | 05-14-2009 |
20090283370 | Immobilizer for Shopping Carts - Immobilizer for shopping trolleys which is activated and deactivated by means of magnetic forces, in which lower forces are required to deactivate the immobilizer than to activate it. This makes it possible for the immobilizer to be deactivated both by a “strong” magnetic strip, such as is used for activation, and by a “weak” magnetic strip. The “strong” magnetic strip is located at the boundary of the permissible region, and one or more “weak” magnetic strips are located within the permissible region in order to activate immobilizers which are located within the permissible region and are still activated for some reason or another. | 11-19-2009 |
20100012438 | Immobilizer - Immobilizer for shopping trolleys, wherein the castor angle of the steering rollers when the immobilizer is activated is equal to zero, as a result of which the steering rollers can set themselves stochastically to an oblique or transverse position with respect to the direction of travel, making the shopping trolley much more difficult to push. | 01-21-2010 |
20120325593 | CART BRAKE AND CART WITH USER-OPERABLE BRAKE - A brake for a wheeled cart of the type having a container supported on at least a pair of rear wheels carried on a cart frame, that includes a brake manipulator pivotally mounted on the cart frame in, and including a handle portion and a cam portion. An elongate brake member is pivotally attached to the manipulator and extends into a position proximate the at least one. A braking element is positioned on a lower end of the brake member for being selectively moved into and out of frictional braking engagement with a tread surface of the wheel. | 12-27-2012 |
20130306411 | Cart Braking System - A braking system for a cart is described herein. The braking system can include a pair of chocks positioned proximate to a wheel of a wheel assembly, where the wheel assembly is coupled to a cart frame. The braking system can also include a handle mechanically coupled to the cart frame, where the handle has an engaged position when a force is applied to the handle, and where the handle has a disengaged position when no force is applied to the handle. The braking system can also include a brake release mechanism coupled to the pair of chocks and the handle. When the handle is in the disengaged position, the pair of chocks are engaged with the wheel and the brake release mechanism is disengaged. When the handle is in the engaged position, the pair of chocks are disengaged from the wheel and the brake release mechanism is engaged. | 11-21-2013 |
20150090539 | Brake Mechanism for Grocery and other User-Propelled Carts - An brake mechanism adapted to be secured to the rear wheels of a user-propelled cart, such as a grocery cart, includes a chock member for chocking wheel when brake mechanism is in the deployed, or braking position. Brake mechanism further includes a chock support member for rotatably securing the chock member to the wheel attachment members. In this regard, the chock support member rotatably secures chock member to wheel attachment member such that chock member can be selectively rotated, by a user of the cart, from an upward, or non-braking, position to a deployed, or braking position. | 04-02-2015 |
