Abstract

(57) [Abstract] (Correction) [Problem] 4 When loading a trolley with casters, try to climb the level difference between the roadway and the sidewalk by attaching a caterpillar to the trolley, and when it is empty and a small amount of By using a trolley with 4 casters as a two-wheel carrier when transporting luggage, it is possible to carry and carry more quickly because no rotating casters are used. SOLUTION: A caterpillar C is attached to an inner tip of a rotating caster 1 of a dolly, and the rotating caster 1 of the dolly is floated on a sidewalk to try to get over a step.
A guide pipe D that can be used as a two-wheel carrier with a trolley with 4 casters when the device is empty and when carrying a small amount of luggage is installed in a U shape on both sides of the trolley.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention, when carrying luggage by truck from a truck or the like, when carrying heavy luggage, the rotating caster 1 of the truck cannot climb over the sidewalk at the step between the roadway and the sidewalk. By attaching it to the inner tip of the rotating caster 1 of the dolly, it is intended to get over the step between the roadway and the sidewalk.

Further, when the empty cart is pushed back to the truck or the like after the transportation of the luggage, traveling using the four casters 1 and 2 of the cart is not quick as the rotary caster 1 is damaged. If the dolly with 1.2 is empty and if there is a small amount of luggage, a two-wheel carrier

FIG.

[FIG. 6] It is intended to be used as a vehicle for speeding up traveling.

[0003]

[Prior art]

 The conventional dolly has two rotating casters 1 on the plate of the pedestal. Two casters 2 are attached to all four, and the hand-operated pipe A is attached to the base for use.

Therefore, when carrying a heavy load from a truck or the like by a dolly, if there is a step, it is impossible to get over the sidewalk. You have to turn around and unload your luggage over a stepless sidewalk.

Further, when the trolley with four casters is emptied and returned to the truck after the transportation of the luggage, the four casters of the trolley are used. It becomes extremely noisy, and some transport-related employees see the rotating caster 1 floating in the air when the truck is running when it is empty.

[0006]

[Problems to be solved by the device]

 According to the present invention, when carrying a heavy load on a dolly, a transport-related employee wants to unload the step of a roadway and a sidewalk by attaching a caterpillar C to an inner end of a rotating caster of the dolly. It aims to increase work efficiency by climbing the sidewalk closest to the place.

[0007] Furthermore, when the empty truck is pushed to return to a truck or the like after the transportation of the luggage is finished, it is not swiftly moved by using the four casters of the truck. Two-wheel carrier for transportation

FIG.

[FIG. 6] It is characterized in that it is used as, and tries to speed up running.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is intended to solve the problem by attaching a caterpillar C to the inner tip of the trolley rotating caster 1 so that it can freely go up and down the step of the sidewalk when loading and unloading luggage. is there.

[0009] In addition, in the case of carrying an empty trolley and a small amount of luggage, both sides of the trolley are provided in order to speed up traveling.

FIG. 7 is a two-wheel carrier to which a U-shaped guide pipe D for expansion (a) and folding (b) is attached as shown in FIG.

FIG.

[Fig. 6] It is intended to be used as an object to speed up transportation and traveling.

[0010]

【Example】

 By attaching the caterpillar C to the inner tip of the rotating caster 1 of the dolly, the step on the sidewalk can be freely climbed, and it is not necessary to make a detour to a place without a step.

In addition, when the dolly is empty and when carrying a small amount of luggage, attach a guide pipe D to the dolly and attach it to a two-wheel carrier.

FIG.

[Fig. 6] It is characterized in that it can be used for transportation and can be quickly returned to a truck or the like because it does not use two rotating casters 1 out of the 4 casters of the trolley, by being used as. .

[0012]

[Effect of the Invention] As described above, the present invention has a problem in how the transportation-related employees can complete each pick-up and delivery only for the work whose time is limited. By attaching the caterpillar C to the inner tip of the rotating caster 1 of the dolly, the step between the roadway and the pedestrian can be freely climbed, and it is necessary to make a detour to a place without a step. Not the effect.

When the truck is empty and when carrying a small amount of luggage, a guide pipe D is attached to the truck to mount the two-wheel carrier.

FIG.

[Fig. 6] By using as two carriage casters among the four casters of the trolley, it can be used for traveling and transported, and can be quickly returned to a truck or the like to work in a short time. The feature is the effect that can be done.

[0009] In addition, in the case of carrying an empty trolley and a small amount of luggage, when the guide pipes are stored on both sides of the trolley as shown in FIG. It is used as a two-wheel carrier [Fig. 5] and [Fig. 6] with a guide pipe D that can be used for both expansion and contraction methods (D) and (b) and folding (D ') specifications. Is intended to be quick.
