Description

The present invention devised to achieve the above-described object is a vehicle-mounted cart that is loaded and unloaded on a vehicle, and is provided on a vehicle with a cart body on which a transported article is placed and a lower portion of the cart body. Sometimes the in-vehicle load support part that supports the weight of the cart body , the legs that extend downward from the four corners of the cart body , and the legs are mounted below the in-vehicle load support part. and a vehicle exterior wheel which supports the weight of the cart body when unloaded, legs, by bending the legs, have a joint mechanism for moving the outside wheel than height of the vehicle for load-bearing part The joint mechanism has an inner joint part that is bent only inward of the cart body and an outer joint part that is bent only outward of the cart body, and the legs bent inward of the cart body by the inner joint part. At the bottom of the cart Becomes Tsu posture, a cart is installed in a vehicle, is outwardly bent legs of the cart main body, characterized in that a posture along the sides of the cart main body by an outer joint.

In the vehicle-mounted cart of the present invention, the inner joint portion is disposed below the outer joint portion, and the inner joint portion bends inward of the cart main body by the inner joint portion so that the posture along the lower portion of the cart main body is The vehicle external wheel attached to the leg that has been bent is bent to the outside of the cart body by the outer joint part, and is positioned below the outer joint part of the leg that has become a posture along the side of the cart body But you can.

The vehicle-mounted cart of the present invention has a vehicle contact portion that is pressed against the vehicle when the legs are moved below the joint mechanism in a direction in which the cart body is mounted on the vehicle, and the vehicle contact portion is pressed against the vehicle. Thus, the leg may be bent by a joint mechanism.

In the vehicle-mounted cart according to the present invention, the in-vehicle load support portion is provided on the cart main body so as to be movable between a protruding position protruding from the side of the cart main body and a storage position pulled into the lower portion of the cart main body When the vehicle is brought close to the vehicle from the side to be mounted on the vehicle, the in-vehicle load support portion that has become the protruding position may be grounded before the vehicle contact portion is pressed against the vehicle.

The vehicle-mounted cart of the present invention includes a stopper for holding the leg joint mechanism in the straightened state, and a switching mechanism for switching the joint mechanism straightened by the stopper to a bendable state. The mechanism may be a mechanism in which the joint mechanism of the left leg and the joint mechanism of the right leg of the cart body are independently switched between the straightened state and the bendable state.

In the vehicle-mounted cart according to the present invention, the in-vehicle load support portion may have in-vehicle wheels that travel in the vehicle when placed on the vehicle.

An assembly kit for a vehicle mounting cart according to the present invention is an assembly kit for a vehicle mounting cart having the above-described components of the vehicle mounting cart.

When loading a vehicle- mounted cart into the vehicle, the cart body is laid sideways near the trunk floor of the vehicle using wheels for outside the vehicle, and the in-vehicle load support portion provided on the cart body is placed on the trunk floor or the like. With the weight of the main body supported by the vehicle , the cart main body is pushed into the back of the trunk floor or the like while the legs extending downward from the four corners of the cart main body are bent by the joint mechanism. Here, the joint mechanism has an inner joint part that bends only to the inside of the cart body and an outer joint part that bends only to the outside of the cart body, and the leg closer to the vehicle has an inner joint. It bends inward of the cart body by the part and becomes a posture along the lower part of the cart body, and the leg far from the vehicle bends outward of the cart body by the outer joint part and the posture along the side of the cart body. Become. Thus , the cart body can be loaded on the vehicle without lifting, and the burden of mounting work can be reduced. Further, since it is not necessary to insert a leg into the gap between the lower surface of the trunk floor of the vehicle and the road surface as in the conventional example, the burden of mounting work can be reduced even for a vehicle having a narrow gap.
