FIG. 3 is a front perspective view showing an increased capacity state of the entire handcart 100 according to the first embodiment. FIG. 4 is a side view showing an increased capacity state of the entire handcart 100 according to the first embodiment.

  The handcart 100 according to the present embodiment mainly includes a pair of front wheel frames 111L and 111R, a pair of front wheels 112L and 112R, a pair of rear wheel frames 113L and 113R, and a pair of rear wheels 114L and 114R. A pair of connecting members 116L and 116R, a pair of link members 117L and 117R, a bag mounting frame 118, vertical frames 131L and 131R, a handle 121, a bag body 150, and a lid 160 are provided. The above frame group is also collectively referred to as a plurality of frames.

  The upper ends of the front wheel frames 111L and 111R are connected to the connecting members 116L and 116R. The rear wheel frames 113L and 113R are also connected to the connecting members 116L and 116R.

  Front wheels 112L and 112R are rotatably attached to lower ends of the front wheel frames 111L and 111R, respectively. The front wheels 112L and 112R are attached to the front wheel frames 111L and 111R so as to be able to turn (swing) in the left-right direction. Thereby, the user can advance the wheelbarrow 100 in the direction which wants to go. Each of the front wheels 112L and 112R used in the handcart 100 of the present embodiment has rotation restricting slides 115L and 115R. The user can permit or restrict the rotation of the front wheels 112L and 112R in the left-right direction with respect to the front wheel frames 111L and 111R by changing the vertical positions of the rotation restriction slides 115L and 115R. .

  Rear wheels 114L and 114R are attached to the lower ends of the rear wheel frames 113L and 113R, respectively. Further, in the vicinity and inside of the rear wheels 114L and 114R of the rear wheel frames 113L and 113R, a braking force is applied to the rear wheels 114L and 114R via a brake bar 123 and a wire (not shown) as described later. A wheel contact portion 164 is attached.

  Each of the pair of vertical frames 131L and 131R is inserted through the connecting members 116L and 116R. The left and right connecting members 116L and 116R are supported by a horizontal support member 132. Two slide members 135 are slidably provided on the horizontal support member 132. The user can release the locked state of the positions of the vertical frames 131L and 131R with respect to the connecting members 116L and 116R by bringing the two slide members 135 close to each other with fingers. Accordingly, the user can adjust the positions of the vertical frames 131L and 131R in the substantially vertical direction with respect to the connecting members 116L and 116R. That is, the user can adjust the height of the handle 121.

  The left and right ends of the handle 121 are supported by the upper ends of the left and right vertical frames 131L and 131R, respectively. The handle 121 and the vertical frames 131L and 131R form a substantially inverted U-shaped frame when viewed from the front.

  A brake bar 123 is attached to the front of the handle 121 so as to be rotatable in the vertical direction. When the user operates the brake bar 123, the wheel contact portion 164 contacts the rear wheels 114L and 114R via a wire (not shown). As a result, braking force is applied to the rear wheels 114L and 114R.

  One end of each of the link members 117L and 117R is axially attached to the upper and lower central portions of the front wheel frames 111L and 111R, and the other end is axially attached to the upper and lower central portions of the rear wheel frames 113L and 113R.

  The connecting members 116L and 116R support the left and right ends of the rear portion of the bag mounting frame 118. In the present embodiment, the bag attachment frame 118 is supported at its front left and right ends by support members 119 attached to the front wheel frames 111L and 111R.

  The bag mounting frame 118 is a substantially square-shaped member in plan view. The bag mounting frame 118 holds the upper end of the bag body 150, that is, the opening portion of the bag body 150.

  The lid 160 serves as a lid 161 and a seating surface 162 of the bag body 150. The lid portion 160 is pivotally attached to the rear portion of the bag mounting frame 118 or the connecting members 116L and 116R. The user can open the upper portion of the bag body 150 by rotating the lid portion 160 rearward and upward. Conversely, the user can close the bag body 150 by tilting the lid 160. Alternatively, the user can sit on the seating surface 162 by tilting the lid 160.

  In addition to the above, for example, a reinforcing frame may be attached between the pair of front wheel frames 111L and 111R, or a reinforcing frame may be attached between the pair of rear wheel frames 113L and 113R. .

The handcart 100 may be configured to be compactly folded in the front-rear direction or the left-right direction.
