Open the CIPO recordAbstract From the Canadian patent
In order to prevent unused shopping carts from standing around in parking lots, they may be fitted with coin locks which make it possible for the said shopping carts to be loaned out against a deposit. Known coin-locks may be fitted either centrally of the handle area or to the lateral walls of the basket, but this type of arrangement is not without its disadvantages. For instance it has, been found that the position of the coin-locks fitted to the handle of the cart may be wantonly altered and furthermore, locks so fitted interfere with the seating area of a child to be carried in the cart. Coin-locks fitted laterally to the basket of the cart increase the width of the cart unnecessarily.
