Description

The present invention relates to a wheelbarrow such as a silver car or a walking car.

In this type of wheelbarrow, the left and right leg frames that rotatably support the front and rear wheels are connected to the lower end of the steering frame that extends downward from the steering portion at the upper end, and between the left and right leg frames. A seating plate that can be seated is provided.

By the way, in such a wheelbarrow, a shopping cart for storing products to be purchased in the store can be placed vertically on the seating plate with its longitudinal direction extended in the front-rear direction. Therefore, wheelbarrow users will be able to shop smoothly in the store.

In that case, when the shopping cart is placed vertically on the seating plate, it is necessary to make the front-rear length of the seating plate excessively long according to the front-rear length of the shopping cart. Therefore, it is undeniable that the seating position is closer to the front when seated on the seating plate, and in this case, the load applied to the seating plate tends to be biased to the front side and the rear wheels tend to float, and the wheelbarrow becomes unstable when seated. There is a risk of a situation.

Moreover, when the wheelbarrow has a folding function, it is difficult to make it compact even if it is folded with an excessively long seating plate in the front-rear direction, and it becomes difficult to store it in a narrow space.

Therefore, conventionally, a foldable backrest plate connected by a hinge is provided at the rear end of the seating plate, and the backrest plate that has been laid down on the seating plate can be moved forward and backward with respect to the seating plate. It is known that a shopping cart can be placed vertically on the back surface of a backrest plate without making the seat plate excessively long in the front-rear direction (see Patent Document 1). In this case, the wheelbarrow can be stored in a narrow space without becoming unstable when seated.

In addition, the tip of the backrest plate is provided with a contact piece that comes into contact with the shopping cart from the front, and the contact piece is pressed from the front by an urging means such as an urging spring against the shopping basket to hold the shopping cart on the backrest plate. It is designed to be held smoothly on top.
