Description

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 for expanding a cargo bed surface depending on an object to be carried.

[0002]

2. Description of the Related Art Conventionally, various types of trucks have been used for various operations. For example, there are rear cars, unicycles, and low-floor carts with four-wheeled casters, etc., but all of them were not good at surely carrying luggage larger than the bed surface.

[0003]

As a result of various studies in view of the above, the present invention has developed a trolley which is stable and easy to use regardless of the size difference of luggage.

That is, according to the present invention, in a cart having a luggage carrier, wheels, and a handle, a handrail member that is extendable and retractable in a direction of expanding the luggage carrier surface is detachably attached along both left and right edges and a rear edge of the rectangular luggage carrier. It is effective to provide a multi-purpose cart characterized by being provided so that the bent base end portion of the handrail member can be freely inserted into and removed from the pipe fixed to the lower surface of the loading platform.

Further, another multipurpose truck of the present invention is a fixed handrail in which two laterally variable wheels are arranged side by side on the lower surface of a rectangular loading platform having a flat surface, and a handle member is attached along the front end of the loading platform. A rear end edge and left and right side edges of the cargo bed, each of which is bent and is removable in a pipe fixed to the lower surface of the cargo bed and extendable in a direction to expand the cargo bed surface. A handrail member is provided. In any of the above cases, it is more effective to use aluminum or aluminum alloy for the members other than the wheels.

As described above, the handrail member is basically provided along the rear end edge and the left and right side edges of the rectangular luggage carrier so as to prevent the luggage on the luggage carrier from sliding down from the rear side or the left and right sides. is there. The handrail member is made expandable / contractible in the direction in which the luggage carrier expands. Even when a luggage larger than the luggage carrier surface is loaded, it can be pressed from four directions, so that the luggage 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 all, it is possible to handle vertically long, horizontally long or vertically and horizontally larger than the bed surface, which is convenient. Is good.

[0007]

Next, an embodiment of the present invention will be described. FIG.
Using a frame (1) made of a hollow aluminum alloy extruded material having a step in the cross-sectional shape as shown in FIG.
Two load carrier plates (2) made of an extruded aluminum alloy having a cross-sectional shape shown in FIG. 2 were laterally butted and the peripheries thereof were engaged and fixed to form the carrier carrier (3) shown in FIG. A fixed handrail (4) of an outer peripheral grooved pipe made of an extruded aluminum alloy material is erected along the front end edge of the load carrier (3), and a handle of the outer peripheral grooved pipe made of aluminum alloy is further provided at the front end of the load carrier (3). A handle mounting rod (6) (6) made of an aluminum alloy pipe for inserting and locking the base end of the rod (5) was fixed. Further, as shown in FIG. 4, two lateral wheel positioning members (7) and (7) made of the aluminum alloy extruded material shown in FIG. 5 are provided on the back surface of the loading platform (3), and long holes (8) are provided in these. ) Is provided and the rubber tires (9) are attached as shown in FIG. 6, two aluminum alloy square pipe wheel support members (10) are fixed with bolts and nuts (11) as shown in FIG.

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

Further, as shown in FIG. 10, each of the handle mounting rods (6) and (6) is provided with three sets of handle height adjusting holes (19) penetrating the rod (6) in the lateral direction. When the hole (19) and the base end of the handle rod (5) are inserted into the handle mounting rod (6) (6), the handle rod (5)
By aligning the position with the handle fixing hole (20) provided through the base end in the lateral direction and inserting the male and female screw pins (21) penetrating these holes (19) (20), You can select the handle height that is easier for people to use. In addition, on the rear surface of the front part of the loading platform (3) of the truck, the auxiliary legs (22) of the aluminum alloy outer peripheral grooved pipe are provided so that the surface of the loading platform (3) becomes substantially horizontal when the truck is placed on the ground. ) (22) was erected. Further, in the trolley of the present embodiment, since the handle bar (5) is detachable, it is easy to handle when storing or transporting the trolley itself.

In addition to the above handle, the handle (23) is rotatably attached to the fixed handrail (4) at its base end as shown in FIG. It is possible to use a type in which the angle adjusting rod (24) is extended and detachably fixed to the front end of the loading platform (3) with a screw (25). At this time, the tip of the handle angle adjusting rod (24) has a shape capable of being locked stepwise in three places as shown in FIG. Such handles (23)
According to the structure, the screw (25) when not using the trolley
By removing the handle, the handle (23) can be folded on the rear loading platform, 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 expanded and contracted in the expanding direction of the luggage carrier (3) and fixed at arbitrary positions. Therefore, since the flat bed surface can be used more widely, a luggage larger than the bed surface and slippery can be transported particularly advantageously. Further, it is possible to remove all of these handrails, in which case it is possible to load a larger load.
In addition, the use of such a trolley is suitable for transporting container boxes for storing harvested products in agricultural work, transporting seedling boxes for storing rice for planting rice, and transporting other luggage. In addition, since all the constituent members can be made of aluminum alloy, they are extremely lightweight and easy to handle, and since pipes with outer peripheral grooves are used everywhere, they are hard to slip and have high strength.
