JP3078635U - A transport trolley with a sled that can be stored and has a side slip prevention structure - Google Patents

Abstract

(57) [Abstract] [Problem] To be usable on a snowy or frozen surface, in a place without snow, in a building, or the like, and to extend a use range of a transport vehicle. Further, it is possible to secure the stability when carrying the luggage on the snow and on the frozen surface, and to enable the sled to be smoothly taken in and out. When an upper pedal of a bogie is depressed, the bogie is pushed up by a vertical shaft, and a sled faces a floor. When you press the lower pedal on the trolley, the trolley lowers and the six sleds are hidden, and the caster faces the floor.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a transport trolley that can travel on snow, on a frozen surface, in a building, or the like.

[0002]

[Prior art]

 Conventional main transport trucks perform a traveling function only by wheels.

[0003]

[Problems to be solved by the invention]

 However, when used on snow, the wheels did not travel well because the wheels were buried in the snow or the wheels came off on unevenness on the snow, and the wheels of the transport cart did not slide and rotate on the frozen surface. Even with a sled, there is no problem if it is only on snow or frozen surfaces, but it can not be used in places without snow or in buildings, so it is necessary to remove the sled part and troublesome folding work each time Was. Also, due to the operation characteristics of pushing the sled later, the balance may be lost when carrying luggage on the snow or on the frozen surface.

In view of the above, it is an object of the present invention to smoothly use a transport vehicle on snow and on a frozen surface, to secure stability when transporting luggage, and to broaden a range of uses. ing.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a top view of a transportable trolley with a sled that has the anti-slip structure of the present invention. FIG. 3 is a comparison diagram of the overall view when the lifting shaft and the bogie are up and down by the bogie pedal of the transportable bogie with a sled having the anti-slip structure according to the present invention.

[0006] Depressing the upper pedal of the trolley raises the trolley, so that six sleds face the floor. Also, pressing the lower pedal of the four bogies in the same way lowers the bogie, hiding the sled, and the caster part of the bogie faces the floor. This vertical movement is related to the five vertical axes.

[0007] (2) The anti-skid wing has an auxiliary role because it cannot be balanced only by the central sled. In order to further prevent lateral slip, several straight grooves and projections are provided on the bottom surface of the anti-skid wing and the central sled according to the size of the carriage.

[0008] According to the present invention, since the conventional transport truck and the sled are integrated, they can be used on snow, on a frozen surface, in a place without snow, in a building, or the like. Can be. Further, the one-touch stepping device makes it easy to take in and out the sled, and it can be easily performed. Small sleds on both sides of the sled and small and large sleds have straight grooves and projections on the bottom of each sled, so that the transport truck does not break the balance when carrying luggage on snow or on a frozen surface. As described above, the present invention can be used in the snow and other places, is easy to switch, and is an invention useful for expanding the range of use of the transport trolley.
