Abstract

A securing device (1) for carts having a chain (82) with a first end secured to a screw (7) mounted on a cart, a first key secured to a second end of the chain (82), a coin receptor for releasing and retaining an introduced coin (50, 51), and additional apparatus for coupling and uncoupling the cart to and from another parked cart. When a second key (8') secured to the other parked cart is introduced into the securing device (1) to couple and securely hold the cart to the other parked cart, a coin (50, 51) from the coin receptor of the cart is released and the cart can be uncoupled from the other parked cart by introducing a next coin (50, 51) into the coin receptor thereby releasing the second key (8') while the next coin (50, 51) is retained in the coin receptor. The apparatus for coupling and uncoupling includes a pivotable locking part (2) for lockingly engaging the second key (8'), a spring returned part (3 ) biased toward the coin receptor for maintaining the locking part (2) in engagement with the second key (8') and releasing the next coin. Introduction of the second key (8') pivotably urges the locking part (2) into locking engagement with the second key (8') and permits the part (3) to return toward the coin receptor, releasing the next coin and engaging the locking part (2) to maintain the locking part (2) in locking engagement with the second key (8').
