DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trolley used for various purposes, and more particularly to a trolley which is extended by a transported object.

[0002]

2. Description of the Related Art Various types of bogies have been used for various operations. For example, there are a rear car, a unicycle, a low-floor cart with four-wheel casters, and the like, but none of them is capable of reliably transporting a load larger than the loading surface.

[0003]

SUMMARY OF THE INVENTION In view of the foregoing, the present invention has been developed, as a result of various studies, a stable and convenient trolley irrespective of the difference in the size of luggage.

That is, according to the present invention, in a bogie having a loading platform, wheels, and a handle, a handrail member which is extendable and contractible in a direction in which the loading platform surface is extended is detachably provided along left and right side edges and a rear edge of the rectangular loading platform. It is effective to use a multi-purpose trolley characterized in that the trolley is provided such that the bent base end of the handrail member is detachably inserted into a pipe fixed to the lower surface of the loading platform.

In another multi-purpose cart according to the present invention, a fixed handrail is provided in which two laterally variable wheels are juxtaposed on a lower surface of a rectangular carrier having a flat surface, and a handle member is attached along a front end of the carrier. A base portion bent along the rear end edge and the left and right side edges of the loading platform can be inserted into and removed from a pipe fixed to the lower surface of the loading platform, and can extend and contract in the direction of expanding the loading platform surface. A handrail member is provided. In any of the above cases, it is more effective to use aluminum or an aluminum alloy for members other than the wheels.

[0006] As described above, the handrail member is basically provided along the rear end edge and the left and right side edges of the rectangular loading platform to prevent the load on the loading platform from sliding down from the rear and the left and right sides. is there. The reason for making the handrail member expandable and contractable in the direction in which the cargo bed expands is that even if a cargo larger than the cargo bed surface is placed, it can be pressed from all sides, so that the cargo can be stably and safely transported. Furthermore, by removing the handrail member only on the rear end side, only on the left and right sides, or entirely, it is possible to handle a vertically long one, a horizontally long one, or a vertically, horizontally or horizontally larger than the loading surface. Is good.

[0007]

Next, an embodiment of the present invention will be described. FIG.
Using a frame (1) made of a hollow extruded aluminum alloy material having a step in the cross-sectional shape as shown in FIG.
The two loading plates (2) made of an aluminum alloy extruded die having the cross-sectional shape shown in FIG. 3 were abutted in the lateral direction, and their peripheries were engaged and fixed to form a loading platform (3) for the bogie shown in FIG. A fixed handrail (4) for an outer grooved pipe made of an extruded aluminum alloy material is erected along the front edge of the carrier (3), and a handle for an aluminum alloy outer grooved pipe is provided at the front end of the carrier (3). The handle mounting rods (6) and (6) made of an aluminum alloy pipe for inserting and locking the base end of the rod (5) were fixed. As shown in FIG. 4, two lateral wheel positioning members (7) and (7) made of an aluminum alloy extruded die shown in FIG. 5 are provided on the back surface of the loading platform (3). ), And a wheel support member (10) of two aluminum alloy square pipes to which a rubber tire (9) was attached as shown in FIG. 6 was fixed with a bolt nut (11) as shown in FIG.

Next, as shown in FIGS. 8 and 9, the left and right handrails (12) and (13) of an aluminum alloy pipe with an outer peripheral groove can be inserted and removed in the lateral direction on the back surface of the front and rear portions of the carrier (3). The aluminum alloy left and right handrail mounting pipes (14) and (14) to be attached to the vehicle are fixed, and the aluminum alloy outer grooved pipe rear handrail (15) is provided on both sides of the rear end of the back surface of the loading platform (3). The rear handrail mounting pipes (16) and (16), which are removably mounted, were fixed. In addition, nuts (17) are fixed to the side surfaces of both ends of the left and right handrail mounting pipes (14) and (14) and the end portions of the rear handrail mounting pipes (16) and (16) to provide through holes. (12) A thumbscrew (18) was screwed through the nut (17) to lock the base end of (13) (15).

As shown in FIG. 10, the handle mounting rods (6) (6) are provided with three sets of handle height adjusting holes (19) penetrating the rod (6) in the lateral direction. When the base end of the hole (19) and the handle rod (5) are inserted into the handle mounting rods (6) (6), the handle rod (5)
By inserting the male and female screw pins (21) passing through these holes (19) and (20) by aligning them with the handle fixing holes (20) provided through the base end in the lateral direction, It is possible to select a handle height that is easier to use for humans. In addition, on the back surface of the front part of the carrier (3) of the truck, auxiliary legs (22) of an aluminum alloy outer peripheral grooved pipe such that the surface of the carrier (3) is substantially horizontal when the truck is placed on the ground. (22) was established. Further, in the truck of this embodiment, the handle rod (5) is detachable, so that it is easy to handle at the time of storage or when transporting the truck itself.

In addition to the above-mentioned handle, as shown in FIG. 11, the base end of the handle (23) is rotatably mounted on a fixed handrail (4). A type in which the angle adjusting rod (24) is extended and detachably fixed to the front end of the loading platform (3) with the screw (25) can be used. At this time, the distal end of the handle angle adjusting rod (24) has a shape that can be locked at three places in a stepwise manner as shown in FIG. Such handles (23)
According to the structure, when the bogie is not used, the screw (25)
By removing the handle, the handle (23) can be folded on the back carrier, which is convenient.

[0011]

As described above, according to the present invention, the left and right handrails (12) and (13) and the rear handrail (15) can be fixed at any positions by expanding and contracting in the direction in which the carrier (3) expands. Because of the greater availability of the flat bed surface, luggage that is larger and slippery than the bed surface can be transported particularly advantageously. Furthermore, all of these handrails can be removed, in which case it is possible to load even larger loads.
The use of such a trolley is suitable for transporting a container box for storing harvested products in agricultural work, transporting a seedling box for storing seedlings for rice planting, and transporting other luggage. In addition, since the entire components can be made of an aluminum alloy, it is very lightweight and easy to handle, and since the outer peripheral grooved pipe is used everywhere, it is hard to slip and has high strength.
