Abstract

(57) [Summary] [Purpose] The purpose of the present invention is to provide a carrier that can be used as a push car or a sled as needed by raising and lowering the sled part as appropriate. [Structure] A carrier main body 2 and a sled portion 3 are provided. The carrier main body 2 is composed of a flat rectangular loading platform 2A and front, rear, left and right wheels 2C1 and 2D1 arranged on the lower surface of the loading platform. The sled portion 3 is vertically movably connected to the lower surface of the loading platform 2A via an elevator link mechanism 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This plan relates to a carrier that can be used as a push car or sled, if necessary.

[0002]

[Prior art]

 Conventional push carts or sleds are manufactured and used separately.

[0003]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. When unloading work in a snowfall area, for example, when trying to carry a load unloaded from a truck into a warehouse, put the load unloaded from the truck on a sled, carry it over the snow surface to the warehouse entrance, and then push the cart. It is transferred to the warehouse and carried into the warehouse. For this reason, the work during the winter period is more burdensome in terms of work time and labor than that during the summer period, which is a serious problem.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, the present application is composed of a carrier main body 2 and a sled portion 3, and the carrier main body 2 includes a flat rectangular carrier 2A and front and rear wheels 2C 1 and 2D1 arranged on the lower surface of the carrier. And a sled portion 3 is movably connected to the lower surface of the loading platform 2A via a lifting link mechanism 4. In this case, the pusher portion of the carrier body 2 can be provided with an operating portion 5 for expanding and contracting the lifting link mechanism 4.

【Example】

 Examples will be described with reference to the drawings. 1 is a carrier according to the present invention, which includes a carrier body 2 and a sled portion 3. The carrier main body 2 includes a flat rectangular loading platform 2A, a pusher 2B standing upright behind the loading platform, front left and right wheel brackets 2C and rear left and right wheel brackets protruding from the bottom surface of the loading platform. 2D and wheels 2C1 and 2D1 that are attached to these wheel brackets so as to rotate in the front-rear direction. Reference numeral 2B1 is a reinforcing frame stretched at a predetermined position of the pusher. Reference numeral 3 denotes a sled portion connected to the lower surface of the loading platform 2A via a lifting link mechanism 4, and curved plates 3B are formed in front of and behind the flat rectangular sled plate 3A.

Therefore, the ascending / descending link mechanism 4 is composed of left and right link portions 4A and 4A. The link portion 4A has the rear ends of the links 4A2 and 4A3 of the same length intersecting at the center pin 4A1 and the lower surface of the loading platform 2A. An elongated hole which is connected to a bracket 2A1 provided on the rear side and a bracket 3C provided on the rear side of the upper surface of the sled portion 3 by pins 4A21 and 4A31, and the front ends of the links 4A3 and 4A2 are provided on the front side of the lower surface of the loading platform 2A. And a bracket 2A2 having a long hole provided in front of the upper surface of the sled portion 3 are connected by pins 4A32, 4A22.

Reference numeral 5 denotes an operating portion, which is a connecting rod 5A for connecting the left and right pins 4A32, a block-shaped moving element 5B provided at the center of the connecting rod 5A, and a screw provided on the moving element 5B. An operating rod 5D having a hole 5C, a threaded portion 5D1 screwed into the hole 5C, a vertical operating rod 5F connected to the rear end of the operating rod 5D via a bevel gear mechanism 5E, and this vertical operating rod. The handle 5H is connected to the upper end of the rod 5F via a bevel gear mechanism 5G. Reference numeral 5I is a bearing of the operating rod 5D, which is provided so as to project from the lower surface of the luggage carrier.

The operation will be described together with the effects.

[0010]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. Since the sled portion 3 can be moved up and down by rotating the handle, it can be used as a push car or a sled as required. As a result, the time and physical strength required for transportation can be reduced, so that the transportation work can be dramatically improved, which in turn contributes to the reduction of transportation costs in companies.
