Description

  The present invention relates to a cradle type unicycle for transporting heavy objects such as plants, stones, and sand using a unicycle in gardening, farming, civil engineering, and the like.

  Conventionally, it has been difficult to manually transport heavy objects such as stones, rocks or planted trees. In particular, carrying heavy objects using a unicycle is difficult to load the load on the carrier, and it is difficult to move the unicycle while keeping a balance after being loaded.

  For example, Japanese Utility Model Laid-Open Publication No. 58-58970 proposes that a transported object is sandwiched between two main rods and transported with the main rod closed. Japanese Patent Application Laid-Open No. 2004-123071 proposes a structure in which a slide vehicle body is provided on a transport handle, and a transported object is sandwiched from the front and rear by the slide vehicle body and lifted.

  However, the one disclosed in Japanese Utility Model Publication No. 58-58970 has a high risk of falling the material during transportation, and it is still difficult to transport the material while preventing this. In addition, the thing of Unexamined-Japanese-Patent No. 2004-123071 also tends to drop a conveyance thing from front and back pinching, and it is not easy to carry it, preventing this.

In addition, these conventional examples are difficult because the work of placing a heavy load on the cargo bed becomes heavy labor.
Japanese Utility Model Publication No. 58-58970 Japanese Patent Laid-Open No. 2004-123071

  This device eliminates the disadvantages of the conventional unicycle, and when carrying heavy objects such as plants, stones, sand, etc. using a unicycle in gardening, farming, civil engineering, etc., it is easy to load luggage on the unicycle alone, An object of the present invention is to provide a swivel type unicycle that can be easily moved.

  The cradle type unicycle for carrying goods of this invention is a base having wheels, two hoppers having an L-shaped cross section that has a fulcrum on the base and opens and closes to the left and right, and the left and right hoppers. It is characterized by comprising two operation handles that can open the hopper left and right.

  Still further, the tip of the hopper has a vertical surface so that the unicycle can be stood up and loaded with luggage.

  Using the cradle type unicycle for carrying luggage of this device, when carrying heavy objects such as plants, stones, sand, etc., by lifting the unicycle and opening the left and right hoppers, While being able to be loaded and transported on a unicycle, the load placed on the loading platform can be easily transported without dropping, improving workability.

The luggage type unicycle for carrying goods according to the present invention will be described below with reference to the drawings.
FIG. 1 is an external view of a cradle type unicycle 1 for carrying goods according to the present invention. FIG. 2 shows an operation of placing stones, rocks, etc. on the cargo bed using the above-described cradle type unicycle for carrying the present invention. FIG. 3 is a front view of the operation of placing stones, rocks, etc. on the cargo bed using the cradle type unicycle for carrying the luggage of the present invention.

  As shown in FIG. 1, a baggage-type unicycle 1 for carrying goods according to the present invention is a unicycle including left and right hoppers 2 and 3, a base 12, left and right handles 4 and 5, and wheels 9. When carrying a load, the load is placed on the base 12 or the hoppers 2 and 3, and the handles 4 and 5 are pulled in a state where the hoppers 2 and 3 are closed, or they are pushed forward to carry. This carrying operation itself is the same as that of a normal civil engineering unicycle.

  As shown in FIG. 1, the hoppers 2, 3 have vertical rising surfaces 10, 11 from horizontal surfaces 13, 14. Further, the bottom surfaces of the hoppers are loosely fitted to the support rods at the tip portions 6 and 7 of the support rods extending from the handles 4 and 5, and the loose fitting portions are hoppers as shown by 21 in FIG. The bottom surface and the tip of the support rod are connected with a rivet or bolt as a support shaft.

  As shown in FIG. 2, the wheel 9 is supported by wheel shaft support rods 23 and 24 supported by a bottom of the base and a wheel support plate 19 (FIG. 1) extending from the base. It is supported. Each hopper has a fulcrum at the front 17 of the handle rotation shaft support point 8 where the support rod intersects, and when the handles 4 and 5 are opened and closed, the tip portions 6 and 7 of the support rod open and close left and right. In response to this, the hoppers 2 and 3 open and close around the fulcrum 17. At this time, as described above, the tip end portions 6 and 7 of the support rod and the bottom surface of the hopper are loosely fitted so that when the handles 4 and 5 are opened, the hopper is related to the fulcrum 8 and the fulcrum 17. Thus, it opens wide while rotating slightly around the shafts 6 and 7.

The loading operation of the baggage carrying unicycle of the present invention is as follows.
As shown in FIG. 2, the unicycle is raised with respect to the rock or stone 25 to be transported, and the vertical rising surfaces 10 and 11 are brought close to the rock while being brought along the ground. Thereafter, as shown in FIG. 3, the hoppers 2 and 3 are opened by the handles 4 and 5, and the rock is sandwiched from the left and right. When the handles 4 and 5 are raised toward the front after the sandwiching, the rocks and the like can be placed on the flat portions 13 and 14 of the hoppers 2 and 3 or the base 12 according to the principle of the lever with the wheel as a supporting point. At this time, although not shown, it is desirable to lock the left and right handles so that they do not move.

  The rocks and the like placed on the loading platform may be transported in the same manner as a normal unicycle, and may be lowered at the destination by the reverse operation.

  The unicycle for carrying goods according to the present invention crawls and lifts heavy objects such as rocks between the left and right hoppers, so that the work of placing on the cargo bed becomes easy and the industrial utility is high.

It is a figure which shows the whole perspective view of the unicycle for baggage conveyance of this invention. It is the image figure seen from the side when carrying a load with the unicycle for baggage transportation of this device. It is the image figure seen from the front when carrying a load with the unicycle for baggage transportation of this device.
