Description

  The present invention relates to a vehicle-mounted cart used in a store such as a supermarket or a shopping center.

  Shopping carts (hereinafter referred to as carts) used in stores such as supermarkets and shopping centers are usually owned by stores. Therefore, the customer places the goods purchased and settled in the store on the cart, carries it to the private car in the parking lot, transfers the goods from the cart to the private car, and then turns the empty cart into the predetermined cart installed in the parking lot. It must be returned to the storage.

  On the other hand, if the customer can prepare his own cart that can be loaded onto the private car, it is not necessary to return the cart to the cart storage area. That is, the customer can take his / her cart from the private car parked at the parking lot and use it for purchase / settlement of goods at the store, and then carry the goods and cart to the private car at the parking lot and return home.

  In order to mount the cart on a private vehicle, it is necessary to fold the legs of the cart in order to reduce the mounting space, and various inventions have been proposed (Patent Documents 1, 2, etc.). However, these carts lift a compact cart by folding legs or the like and carry it into a private vehicle (vehicle), so that the work load when mounting the cart on the vehicle is large.

  As a vehicle-mounted cart designed to reduce the work burden when mounted on a vehicle, a side-view substantially circular (C-shaped) leg having a notch in the front is configured to be extendable and retractable along the circumferential direction. There is known one in which a transported article storage unit is disposed at the upper part of the leg and a caster is disposed at the lower part of the leg (Patent Document 3). This vehicle-mounted cart inserts leg cutouts into the trunk floor of the vehicle from the rear to seat the material storage section on the trunk floor, and then contracts the legs upward along its circumferential direction. The legs are housed in the trunk.

  According to such a vehicle-mounted cart, the work of lifting the cart and bringing it into the vehicle becomes unnecessary, so that the work burden when mounting the vehicle on the vehicle can be reduced.
