Description

  The present invention is capable of transporting rough roads and steps, making it possible to transport between the fields of the fields, watering the fields, harvesting operations, etc., compactly folding, and storing in the trunk space of a passenger car, shopping cart It relates to a multifunctional tricycle that can also be used as a car cart.

  Conventional push-type transport vehicles include hand-drawn unicycle and 4-wheel bogie type transport vehicles.

  A four-wheel carriage type vehicle cannot enter a vineyard in the field and harvest or carry a water container. A hand-held unicycle can enter a vineyard in a field, but has a high center of gravity. When the container was transported, the water surface swayed from side to side and the balance was easily lost, and arm strength was required. Furthermore, the storage capacity was poor and could not fit in the trunk space of a passenger car.

JP-A-2016-13723 Carriage for transportation Utility model registration 3075031 Hand-held tricycle carrier

  The conventional push-type four-wheel carriage shown in Japanese Unexamined Patent Application Publication No. 2016-13723 is composed of four wheels on the lower side of the carriage frame, but most of the wheels are rigid and have a small diameter. In places with unevenness such as gardens, hand-operated operability is poor, and the range of work places using carts is limited to be flat.

  For this reason, in agriculture, gardens, etc., the ones that are changed from hand-wheeled single-wheel carriers and hand-wheeled single-wheel carriers to three-wheelers shown in Utility Model Registration 3075031 Hand-held three-wheel vehicles are mainly used for transportation. However, the higher the center of gravity and the heavier the weight that can be put on the carrier, the worse the stability, so the burden on older people and women was greater, and it was a transport vehicle for people with physical strength.

  The multi-function three-wheel carriage of the present invention is provided with a wheel at the front end of a frame carrier assembled in a plane triangle shape so as to be able to roll in the direction of the front end, and on the lower surface of the other two end portions, the caster wheel can be freely controlled. Is provided.

  A handle is provided in the vicinity of the frame connecting the two ends of the frame loading platform on which the caster wheels are provided, so as to be rotatable about an axis parallel to the frame.

The handle is provided by a steel material such as a lightweight pipe that is rotatably supported at two points close to the width of the frame connecting the both ends of the frame loading platform provided with caster wheels, and forms a U-shape.

  According to the multi-function tricycle cart of the present invention, the multi-function tricycle cart that has a low center of gravity of the carrier, is easy to carry, can be folded compactly and can be stored in the trunk space of a passenger car, and can be used as a shopping cart or a carry cart. Can be provided.

  In particular, if the front wheels are thick and large, and the handle is fixed in the direction of the extension of the frame loading platform, it will not be buried in soft ground such as a hand-held unicycle, and will easily get over uneven road surfaces. It becomes possible.

  Furthermore, if the handle is fixed directly above, it can be lightly pushed and pulled on a flat road surface such as a four-wheel carriage type vehicle, and can be easily changed in direction with caster wheels. Furthermore, if the handle is folded in the direction of the frame, it can be stored in the trunk space of a passenger car.

FIG. 1 shows an embodiment of the present invention. The multi-function three-wheel carriage of the present invention is provided with a wheel at the front end of a frame carrier assembled in a plane triangle shape so as to be able to roll in the direction of the front end, and on the lower surface of the other two end portions, the caster wheel can be freely controlled. Is provided.

  A handle is provided in the vicinity of the frame connecting both ends of the frame carrier wheel provided with caster wheels so as to be rotatable about an axis parallel to the frame. The rotating shaft of the handle is connected to the frame carrier.

The handle is provided by a steel material such as a lightweight pipe that is rotatably supported at two points close to the width of the frame connecting the both ends of the frame loading platform provided with caster wheels, and forms a U-shape.

  According to this structure, the center of gravity of the loading platform is low, the carrying operation is easy, it can be folded compactly and can be stored in the trunk space of a passenger car, and it can provide a multi-function three-wheel cart that can also be used as a shopping cart or carry cart. is there.

  FIG. 2 shows a state of being folded compactly, and shows that it is configured to be flat and can be easily stored in a trunk space of a passenger car.

  FIG. 3 shows a form of a hand-held unicycle vehicle in which the handle is fixed in the extension line direction of the frame carrier. This mode of operation is illustrated in the explanatory diagram of FIG. 6, and the triangular frame carrier can transport the space between the fields without damaging the crops, lowering the center of gravity, and the fulcrum-force point interval from the fulcrum-action point interval. It shows that it becomes a single-wheeled vehicle that can be transported with small force by taking it sufficiently wide.

  FIG. 4 shows a form in which the handle is fixed in the upward direction. This mode of operation is illustrated in the explanatory diagram of FIG. 7, and on a flat road surface such as a four-wheel carriage type transport vehicle, it can be pushed and pulled lightly without needing to be held, and the transport vehicle can be easily turned by caster wheels. It shows that it can be used as a shopping cart.

  FIG. 5 shows fixing means for fixing the handle at an arbitrary position. The handle is provided so as to be able to rotate between zero degrees directly above and 270 degrees when stored. In one example, the handle is fixed at a position of zero degrees and 90 degrees by being sandwiched between frame carriers.

  In another example, one of the hardware having a meshing structure on the opposite surface is fixed to the frame carrier side, and the other is fixed to the handle rotating shaft side, and can be freely switched between fixed and open by the camshaft. ing. This example shows an example of the fixing means, and the multifunctional tricycle of the present application can be realized even if other various fixing methods are used.

  The explanatory diagram of FIG. 8 shows the effect of easily overcoming a large step.

  The explanatory view of FIG. 9 shows a form used as a carry cart.

  In various forms, when a water container, a shopping basket, a harvesting container, etc. are used properly, the front support and the rear support are prevented from moving back and forth, and rubber bands are attached to the retaining holes provided in the both supports. Hang the end of the bag to secure the load.

Since it can be folded compactly and stored in the trunk space of a passenger car, it can also be used as a shopping cart or carry cart.
Furthermore, a multi-functional three-wheeled carriage that can transport between the ridges of the field without damaging the crops by means of the triangular frame carrier can be provided.
