[0001]
TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-held trolley for carrying various kinds of luggage.
[0002]
Problems to be solved by the prior art and the invention
Conventionally, various types of hand-held trolleys, such as one-wheeled and two-wheeled, have been used. However, there are not many known bogies that have a simple structure that can be used for one wheel and two wheels and that are easy to use. In particular, there has been a demand for a bogie which is easy to move on farmland by loading a container storing harvested products for agricultural work.
[0003]
[Means for Solving the Problems]
The present invention has been made to solve such a problem, and an object of the present invention is to provide a hand-held trolley that can be used as a one-wheeled trolley and a two-wheeled trolley and that is easy to carry.
[0004]
In other words, the present invention provides a hand-held handle on the front side of the loading platform, and in a truck provided with a stopper bar for locking the luggage on the tip side of the loading platform, providing a long hole in the reinforcing frame that is bridged in the front-rear direction of the loading platform. The tire support member to which the tire is attached is attached to the long hole so as to be able to move back and forth by using a bolt and a nut.
A tire support member capable of moving back and forth is attached to each of the two fixed reinforcing frames, and a tire is fixed between the tire support members so that the tire can be used as a truck having a single wheel at the center. A tire support member capable of moving back and forth is attached to each of the reinforcement frames, and a tire is fixed to each of the tire support members, so that the tire can be used as a two-wheeled vehicle.
[0005]
【Example】
Next, the present invention will be further described with reference to the drawings.
[0006]
(Example 1)
As shown in FIGS. 1 and 2, a step portion of an outer frame (1) of a hollow stepped pipe made of an extruded aluminum alloy is assembled in a rectangular shape with the stepped portion facing inward and upward, and a bed made of an extruded aluminum alloy plate is attached to the stepped portion. The plate (2) was fitted and mounted to form a carrier (3) having a long longitudinal direction. Then, two channel members made of an extruded material made of an Al alloy are fixed in the longitudinal direction on the lower surface side of the loading platform (3) to form reinforcing frames (4) and (4). A long hole (5)... As shown in FIG. As shown in FIG. 3, a rectangular pipe is bent into a U-shape, and mounting plates (8) and (8) having bolt holes (7) on both sides thereof are fixed to these long holes (5). A tire support member (6) (6) formed by welding and fixing an Al alloy flanged round pipe at the center of the lower surface of the U-shape so as to protrude to one side to form an axle (10) for supporting a rubber tire (9). It was fixed in (12). That is, as shown in FIG. 2, the tire supporting members (6) and (6) are fixed with the side on which the tire (9) is mounted facing outward, so that a motorcycle can be obtained.
[0007]
Further, on the front side of the loading platform (3), an Al alloy grooved pipe having a large number of longitudinal grooves formed on the outer peripheral surface in the circumferential direction is bent so that left and right handle support leg integrated members (13) and (13) are provided. It was welded and fixed to the loading platform (3), and a front side stopper bar (14) for reinforcing the aluminum alloy grooved pipe and preventing the load from slipping was fixed between the integrated members (13) and (13) by welding.
As shown in FIG. 5, Al alloy pipes (15) and (15) are welded and fixed to the lower surfaces on both sides of the tip end of the loading platform (3), respectively, and thumb screws (15) penetrating through the side surfaces of the pipes (15) and (15). 16) and a stopper bar (17) made of an Al alloy grooved pipe which can be slid in the pipes (15) and (15) and fixed at an arbitrary position.
[0008]
In such a two-wheeled vehicle, since the left and right tires (9) and (9) can move in the front-rear direction, the positions of the tires (9) and (9) are shifted back and forth depending on the position of the center of gravity of the load placed on the carrier. Is easy to carry. In addition, the stopper bar (17) at the tip of the carrier expands and contracts in the front-rear direction, so that the carrier can be stably placed on the carrier by positioning the stopper bar according to the size of the carrier.
[0009]
(Example 2)
As shown in FIGS. 6 and 7, L-shaped members (20) and (20) made of Al alloy are fixed by welding to the centers of the lower surfaces of two U-shaped tire support members (6 ′) and (6 ′), respectively. A single-wheel tire was constructed by passing a long screw bolt (21) as an axle and fixing both ends thereof to axle mounting holes (22) of the L-shaped members (20) and (20). The one-wheeled tire is attached to the mounting frame (8) at the upper end of each of the two tire support members (6 ') (6') by using the long holes of the reinforcing frames (4) and (4) on the lower surface of the carrier of FIG. The one wheel bogie can be obtained by fixing the bolts and nuts to (5).
[0010]
Such a one-wheeled vehicle can move the tire position back and forth similarly to the two-wheeled vehicle, and since it is a single wheel, it can be driven in a narrower passage.
[0011]
In the case of a single-wheeled vehicle, only one set of the tire supporting member (6) with the tire (9) attached thereto as shown in FIG. 3 of the first embodiment is directed to the reinforcing frame ( Although it can be realized by bolting nuts in 4), one wheel using a tire support member as shown in FIG. 6 is more preferable from the viewpoint of the strength of the tire mounting portion.
In order to reinforce the handle portion, a reinforcing bar (23) as shown in FIG. 8 may be welded and fixed to the handle support leg integrated members (13) (13) instead of the front side stopper bar (14). The reinforcing bar (23) also serves as a stopper bar (14).
Further, in this embodiment, the Al alloy extruded plate (2) is fixed to the carrier, but in the present invention, even if the extruded plate is removed and the carrier is composed of only a frame, the cargo can store harvested agricultural products. In the case of a large container or the like, the weight is sufficient and the weight is low.
[0012]
【The invention's effect】
As described above, according to the present invention, two wheels and one wheel can be freely selected depending on the place to be used, and the tires can be moved back and forth depending on the position of the center of gravity such as the size of the luggage and the position where the luggage is placed. . In particular, it is suitable for placing about 2 to 4 rectangular containers for storing agricultural crops in the front-rear direction and moving the passage in the field.
