<p>Coin-controlled apparatus (1) for locking shopping carts (C1, C2) together in nested series at a cart parking station having coin-controlled mechanism (3) mounted on a cart (C1), e.g. on the handle (H) of the cart, which is adapted for receiving and releasably locking therein a latch bar (5) on a tether (7) which is attached to the next cart (C2) in the nested series. Deposit of a coin (Z) is required to release the latch bar (5) to free the cart (C1) for being wheeled away by the user. The coin (Q) is held until the user brings the cart (C1) back to a cart parking station, nests it in the end cart (C2) at the parking station, and inserts the latch bar (5) which is tethered to the end cart in the mechanism (3) to lock the returned cart to the series and to provide for return of the user's coin (Q). The apparatus has a detent arrangement permitting reduction in its size.</p> |
