Description

  The present invention relates to a shopping cart used when shopping at a store such as a supermarket.

  There are types of shopping carts that not only carry shopping carts, but also allow children to be carried with them for convenience when shopping with children. This type is generally provided with an infant seat where infants can sit (Patent Documents 1 to 3), but in recent years, a floor on which a child (infant or lower grade school child) can stand upright A device provided with a surface (step plate) has also been proposed (Patent Documents 4 and 5).

  The shopping carts of Patent Documents 4 and 5 include an undercarriage, a support column, an operation handle, and an upper car frame. The step plate is provided on the chassis, and the upper car frame allows an infant to sit on an infant. Is provided. The pillar has a vertical member that stands upright from the chassis, a support member that supports the vertical member, and a horizontal member that connects both side portions (vertical portions) of the vertical member. The vertical member has its upper end bent backward, folded back and bent forward (this part is referred to as a "lateral part" for convenience), and then bent left and right to be connected (this part is referred to as "front" for convenience). "Part".). The lateral portion forms an adult (customer) handle. The front portion forms a child handle which is held by a child standing on the step board. Further, the lateral portion and the front portion form a "frame" that surrounds the periphery except the rear side, and this frame functions as a guide frame that limits the moving range of the child standing on the step plate to a predetermined range. .

However, the shopping carts of Patent Documents 4 and 5 have the following problems.
(A) When a child rides on the step board, there is a possibility that his / her foot may be accidentally caught on the rear end of the step board for the child. In addition, when the customer pushes the shopping cart and walks, his / her feet may come out too much forward and hit the rear end of the step plate. At these times, since the step plate is made of metal and hard, it causes pain in the foot.
(A) The lateral part regulates the lateral movement range mainly for the upper arm of the child standing on the step board. In addition, the support member of the column also regulates the lateral movement range of the lower limb of the child standing on the step board. However, since there is no such restriction function between the vertical member of the support column and the support member, there is a risk that the child will protrude outward from this interval.
(C) The upper car frame mainly regulates the forward movement range around the belly of the child standing on the step board. However, below the upper car frame, there is no such regulatory function, so there is a risk of children protruding from this lower part to the front.

  Therefore, an object of the present invention is to address the above problem (a) and to prevent a child standing on a child step board from protruding between the first support pillar and the second support pillar to the outside. To make the ride more stable.
