Description

  The present invention relates to a one-handed wheelbarrow.

  The present applicant has proposed a one-handed wheelbarrow for carrying heavy luggage such as shopping bags and travel bags (see Patent Document 1).

JP 2012-17004 A

  However, in the conventional one-handed wheelbarrow, the horizontal bar connected to the intermediate height position of the handle bar is provided along the center line in the left-right direction when seen in a plan view. For this reason, when the bag is placed on the bottom frame and used, the recumbency interferes with the upper part of the bag, so that the upper part of the bag has to be left and placed on the right side. If a heavy bag is placed on the bottom frame in a state tilted to the left or right, the center of gravity will be unevenly distributed to the left or right side, and the one-handed wheelbarrow may swing in the left-right direction and fall down In addition, there is a drawback that it is difficult to run straight.

  Therefore, an object of the present invention is to provide a one-hand barrow that can stably and safely carry heavy loads.

A one-handed handcart according to the present invention includes a bottom frame for placing a bag having four wheels, and is erected upward from the center in the left-right direction of the front side and / or rear side of the bottom frame, In particular, a handle rod having a handle grip portion along the center line in the left-right direction is provided, and a bag support frame is connected to the handle rod at an intermediate height position. In plan view, it is unevenly distributed to the left side or the right side from the center line.
The bag support frame is configured so that the bag is maintained in an upright posture in a use state where the bag is placed on the bottom frame.

  According to the one-handed wheelbarrow of the present invention, even when a heavy load (bag) is placed on the bottom frame, the risk of falling to the left or right can be reduced because the center of gravity exists in the center position in the left-right direction. A stable posture is possible.

It is the front view which showed one Embodiment of this invention. It is the top view which showed the one-handed handcart. It is the side view which showed the one-handed handcart. It is the side view which showed the use condition of the one-hand wheelbarrow. It is the front view which showed other embodiment of this invention. It is the top view which showed other embodiment.

The handle grip portion 8 is gently formed into an upward curved bow shape, and is configured to be easily gripped during use. In addition, the handle bar 2 includes a braking force transmission means for braking the wheel 4 attached to the lower portion of the bottom frame 1 by operating the brake lever 22.
The wheels 4 are provided with a pair of left and right front wheels 4A and 4A which are attached so as to be swingable and swingable, and a pair of left and right rear wheels 4B and 4B fixed in the traveling direction S. ing.

A bag support frame 3 is connected to the handle bar 2 at an intermediate height position, and the bag support frame 3 is unevenly distributed to the left side or the right side from the center line C in a plan view.
The bag support frame 3 is fixed to the upper ends of the outer pipes 20 and 20 as a connecting shape in the front-rear direction, and is bent in a U shape in plan view.
In the use state of FIG. 4, the bag support frame 3 is engaged or hooked to the upper edge of the bag B, and supports the bag B from the side so as to maintain an upright posture.

The handle rod 2 is engaged with a brake lever 22 that is operated in a braking (braking) state, and a swing support member 23 for holding the posture is pivotally attached to the handle grip portion 8. In addition, the handle bar 2 has an expansion / contraction lock means that enables the handle grip portion 8 to be positioned and fixed in multiple stages at a desired height position. The push button type operation unit 24 provided is configured to switch between a telescopic (lock release) state and a restriction (lock) state.
Further, the bottom frame 1 is in the vicinity of the front wheels 4A, 4A, in a free turning state in which the front wheels 4A, 4A can rotate 360 degrees around the vertical axis, A turn switching means 13 is provided that is switchable between a turn restriction state in which the front wheels 4A, 4A are fixed in the direction of travel S.

Next, another embodiment of the one-handed wheelbarrow of the present invention will be described.
As shown in FIGS. 5 and 6, the one-handed wheelbarrow of the present invention includes a bag-mounting bottom frame 1 having four wheels 4, and upwards from the center in the left-right direction of the front side 11 of the bottom frame 1. In addition to being erected, it is provided with a handle rod 2 having a handle grip portion 8 along the horizontal center line C when viewed in plan, and the handle frame 2 has a bag support frame 3 at an intermediate height position. The bag support frame 3 is connected to the left side or the right side from the center line C as viewed in a plan view.
The bottom frame 1 is manufactured by bending a metal pipe into a substantially U-shape, and is formed so that a bag B can be placed by laying a horizontal rail in the left-right direction.
The handle rod 2 is a curved arm member that has a vertical connection portion with the bottom frame 1 and supports the handle grip portion 8 at the upper edge in a substantially horizontal shape, and the height of the handle grip portion 8 can be adjusted. Is possible.

  The handle rod 2 has an outer pipe 30 erected at the center in the left-right direction of the front side 11 of the bottom frame 1, and is inserted into the outer pipe 30 so as to be slidable in the vertical direction, and is bent at an upper position. And an inner pipe 31 having a handle grip part 8 at the part. A swingable brake lever 32 is attached to the lower portion of the handle grip portion 8. Further, the handle bar 2 is provided with a braking force transmission means for braking the wheel 4 attached to the lower part of the bottom frame 1 by operating the brake lever 32.

In FIGS. 5 and 6, one end of the bag supporting frame 3 is inserted into an L-shaped joint portion 6 </ b> A that projects from the side of the connecting member 6 that is fixed to the upper end of the outer pipe 30. The bag support frame 3 is unevenly distributed to the left side from the center line C as viewed in a plan view, and the other end is connected to and supported by the rear end of the bottom frame 1 in the traveling direction.
In use, the bag support frame 3 is engaged or hooked to the upper edge portion of the bag B, and supports the bag B from the side so as to maintain an upright posture. That is, the handle bar 2 is configured so that the bag support frame 3 does not interfere with the bag B placed on the bottom frame 1 in an upright posture.

The handle bar 2 has expansion / contraction lock means that enables positioning / fixation in multiple stages at a desired height position of the handle grip portion 8, and this expansion / contraction lock means is provided in the engagement with the outer pipe 30. By inserting the locking pin member 15 into the stop hole, the expansion / contraction (lock release) state and the restriction (lock) state are switched.
Moreover, the bottom frame 1 is provided with the turning switching means 13 equivalent to the above-mentioned embodiment.

  As described above, the one-hand barrow according to the present invention includes the bottom frame 1 for bag placement having four wheels 4, and from the center in the left-right direction of the front side 11 and / or the rear side 12 of the bottom frame 1. In addition to being erected upward, it has a handle bar 2 having a handle grip portion 8 along the center line C in the left-right direction as viewed in plan, and the bag support frame 3 has an intermediate height on the handle bar 2 Since the bag support frame 3 is connected to the position and is unevenly distributed to the left side or the right side from the center line C in plan view, the heavy bag B is placed on the bottom frame 1 and travels. Even in this case, since the center of gravity exists on the center line C in the left-right direction, the risk of falling to the left and right can be reduced, and traveling in a stable posture is possible.

  Moreover, since the bag support frame 3 is configured so that the bag B is maintained in an upright posture in a state where the bag B is placed on the bottom frame 1, the bag B is in an upright posture. It can be placed on the bottom frame 1 without breaking the balance in the left-right direction while supporting it securely, improving the operability and obtaining a one-handed wheelbarrow with excellent aesthetics.
