Description

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

  In this type of handcart, the left and right leg frames that support the front and rear wheels rollably are connected to the lower end of the steering frame that extends downward from the steering section at the upper end, and between the left and right leg frames. A seating plate capable of sitting is provided.

  By the way, in such a wheelbarrow, a shopping cart on which a product to be purchased in the store is placed can be placed vertically on the seating plate with its longitudinal direction extended in the front-rear direction. As a result, users of wheelbarrows can smoothly carry out shopping in the store.

  In this case, when the shopping cart is placed vertically on the seat board, the front-back length of the seat board needs to be excessively long according to the front-back length of the shopping cart. Therefore, it is unavoidable that the seating position is moved to the front when seating on the seating plate, which causes the load applied to the seating plate to be biased to the front side and the rear wheels tend to float, which makes the handcart unstable. There is a risk that it will be in a state of

  In addition, when the handcart has a folding function, it becomes difficult to make it compact even if it is folded with a seat plate that is excessively long in the front-rear direction, and it becomes difficult to store it in a narrow space.

  Therefore, conventionally, by providing a retractable backrest plate connected by a hinge to the rear end of the seating plate, by allowing the backrest plate lying down on the seating plate to move forward and backward with respect to the seating plate, It is known that a shopping cart can be placed vertically on a back surface of a backrest plate without excessively lengthening the seating plate in the front-rear direction (see Patent Document 1). In this case, the trolley does not become unstable when seated and can be stored in a narrow space.

  Further, an abutting piece that abuts against the shopping basket from the front is provided at the tip of the backrest plate, and the abutting piece is pressed from the front against the shopping cart by an urging means such as an urging spring so that the shopping cart rests on the backrest plate. I am trying to hold it smoothly.

JP, 2016-11045, A

  By the way, the above-mentioned prior art requires a backrest plate that can be tilted when a shopping basket is placed, which increases the number of parts and is disadvantageous in reducing the cost.

  The present invention has been made in view of the above points, and an object of the present invention is to make it possible to smoothly hold a shopping cart on a seating plate while eliminating the need for a backrest plate and reducing costs, and to prevent unsuccessful sitting. It is to provide a wheelbarrow that can be stored in a narrow space without becoming stable.

  In order to achieve the above-mentioned object, according to the present invention, a steering frame extending downward from a steering portion at an upper end grasped by a user, and left and right legs connected to lower ends of the steering frame and rotatably supporting front and rear wheels respectively. It is premised on a wheelbarrow provided with a body frame. In addition, a seating plate that can be seated is provided between the left and right leg frames, and a shopping cart for storing items to be purchased in a store can be horizontally placed on the seating plate. Further, the seating plate is set to a front and rear dimension shorter than a dimension in a lateral direction of the shopping basket when the shopping basket is placed horizontally, and is placed in front of the seating plate when the shopping basket is placed horizontally. It is provided with a holding member for holding the protruding portion of the shopping basket that pops out. Then, the holding member is provided with a slider member that can be retracted and retracted between a recessed position that is recessed in the back surface of the seating plate and a protruding position that projects forward from the protruding portion, and a slider member that is provided at the tip of the slider member. When the slider member is projected from the back surface of the seating plate toward the projecting position, the up and down abutting piece that abuts the protruding portion from the front in a state of rising upward, and the abutting piece Urging means for urging the contact piece from the position toward the retracted position and contacting the contact piece with the protruding portion while pressing the contact piece from the front side.

  Further, at the rear end of the seating plate, there is an inclined surface that inclines so that the bottom of the shopping cart slides when it is placed, and the rear end of the bottom of the shopping basket is dropped from the front end of the inclined surface and held. Provide a drop piece. When the shopping cart is placed, the abutting piece is in a state of rising upward so as to press the pop-out portion from the front, and in the state of abutting the pop-out portion, the rear portion of the bottom of the shopping cart is abutted. It may be pushed toward the forward projecting position against the biasing force of the biasing means until the end is dropped from the front end of the inclined surface and held.

  Further, the seating plate may also be used as a lid body that opens and closes the opening of the container provided between the left and right leg frames by a hinge.

  Furthermore, it is preferable that the drop piece has a plate-shaped expanded portion that is expanded in a flat plate shape in both left and right directions from the front end of the inclined surface as a starting point and is formed in a substantially T shape in a plan view. ..

  As mentioned above, in short, it is possible to place the shopping basket horizontally between the left and right leg frames and to provide a seating plate with front and rear dimensions shorter than the dimension of the shopping cart in the lateral direction, In the holding member that holds the protruding portion that protrudes forward of the seating plate, the slider member that can be retracted and retracted between the retracted position of the back surface of the seating plate and the protruding position that protrudes forward of the protruding portion, and the slider member And an urging contact piece that comes into contact with the projecting part from the front in the state of rising upward when projecting toward And means.

  For this reason, when the shopping cart is placed on the seat plate, the slider member is projected to the projecting position so that the abutment piece in the state of being raised upward causes the shopping cart to abut against the protruding portion from the front. On the other hand, when the seat is to be seated, the contact piece is stored on the back surface of the seat plate together with the holding member by the urging means in a state of lying down. This allows the shopping cart to be held smoothly on the seating board while reducing the cost by eliminating the need for a backrest board, and the front-back dimension of the seating board rather than the dimension in the lateral direction of the shopping cart placed horizontally. Even if the is set to be short, the wheelbarrow can be stored in a small space without becoming unstable when sitting.

  In addition, a drop-in piece is provided at the rear end of the seating plate, and when the shopping cart is placed, the bottom of the shopping cart is in contact with the abutting piece that is raised upward so as to press the pop-out portion from the front. By pushing the contact piece toward the forward projecting position against the biasing force of the biasing means until the rear end is dropped from the front end of the inclined surface and held, even if the biasing means biases it. It is possible to smoothly hold the bottom of the shopping basket by dropping the rear end of the bottom of the shopping basket from the front end while sliding the bottom of the shopping basket on the inclined surface against the biasing force.

  Further, by using the seating plate also as a lid that opens and closes the opening of the storage container by a hinge, the seating plate can be effectively used as a cover of the storage container provided below the seating plate.

  Furthermore, by providing a plate-shaped expansion part on the drop-in piece that expands to the left and right in a flat plate shape starting from the front end of the sloped surface, the sloped surface slides and the rear part of the bottom of the shopping basket dropped from the front end of the drop-in piece. The end can be held more smoothly by the large area of the plate-like expanded portion.

At this time, the rear end of the leg K2 of the shopping basket K is made of silicon and is attached to the plate-shaped expansion portion 34 that is expanded in a flat plate shape in both left and right directions from the front end of the inclined surface 331 of each drop piece 33 as a starting point. The sheet material 45 allows the drop-in pieces 33 to be pressed against the plate-shaped expanded portions 34 in a non-slip state.

  Further, since the seating plate 3 is also used as a lid for closing the peripheral edge of the container frame 21 on the upper side of the container 2 by the hinge 31, the lid of the container 2 provided below the seating plate 3 is also used. As a result, the seat plate 3 can be effectively used.

  Furthermore, the front end of the drop piece 33 (of the inclined surface 331) is slid by sliding the inclined surface 331 on each drop piece 33 by the plate-shaped expansion portion 34 that is expanded in a plate shape in both left and right directions from the tip of the inclined surface 331 as a starting point. The rear end of the leg body K2 of the shopping basket K dropped from the front end) can be held more smoothly by the large area of the plate-shaped expansion portion 34.

  It should be noted that the present invention is not limited to the above-mentioned embodiment, and includes various other modified examples. For example, in the above-described embodiment, the drop-in pieces 33, 33 are provided at both left and right positions of the rear end of the seat plate 3, but instead of the drop-in piece or in addition to the drop-in piece, a shopping basket is attached to the rear end of the seat plate. A member for holding from the rear may be provided.

  Further, in the above-described embodiment, the seating plate 3 is also used as a lid for closing the peripheral edge of the upper container frame 21 of the storage container 2, but the seating plate is fixed to the peripheral edge of the upper container frame of the storage container 2. However, in that case, an opening with a lid may be provided around the container.

  Further, in the above-described embodiment, the sheet material 45 made of silicon is attached to the back surface of the contact piece 42 and the plate-like expanded portion 34 of each drop piece 33. Any sheet material may be used as long as it has a larger coefficient of friction than the rear surface of the piece and the expanded portion of each drop piece. Further, the sheet material is not always necessary, and needless to say, the sheet material may not be used, and the friction coefficient may be increased directly with respect to the back surface of the contact piece and the expanded portion of each drop piece. Processing such as groove-shaped processing may be performed.

  In addition, in the above-described embodiment, the vertical length of the front surface of the plate-shaped expansion portion 34 is set to 14 mm, but the vertical length of the front surface of the plate-shaped expansion portion is changed according to the height of the legs of the shopping basket. However, the present invention is not limited to this.

  Further, in the above-described embodiment, the case where the handcart A is used as a silver car has been described, but it goes without saying that the present invention may be applied to a handcart such as a walking car or a cart.
