Further, the ladder body A is pulled out, the shelf plate 7 and the ladder body A are placed on the rectangular underframe 1, and the rectangular underframe 1 is moved.

Further, the base material of the carrier is formed by an aluminum alloy drawn-out long material having a hollow rectangular cross section, and ridges are juxtaposed in the longitudinal direction on the surface of this long material. Since it is cut appropriately to form the desired shape, not only a hollow rectangular shaped steel, but a ridge provided in the length direction of the surface exhibits a kind of rim action, increasing the strength against bending, which is light and strong. This makes it easy for women to handle, and adds a good-looking appearance to the carrier. Since this long material can be appropriately cut to be formed into a desired shape, it is suitable for mass production, the material cost and the processing cost are reduced, and the product is easy to sell.

An embodiment of claim 2 will be described with reference to FIGS.

Joint receivers 8 are provided at the four corners of the rectangular underframe 1 in the front, rear, left and right.
And a supporting projection 9 is continuously provided on the upper part of the joint receiving body 8 so as to project on the rectangular underframe 1. The supporting projection 9 and the joint receiving body 8
The lower portions of the columns 5 in front of and behind the ladder body A are fitted in the and, and the stacking locking portion 10 is fitted to the lower end of the joint receiving body 8 to be fitted to the upper end of the supporting projection 9.

More specifically, similar to the above, the main member of the rectangular underframe 1 is made of an aluminum alloy drawing material having a hollow rectangular cross section, and the freewheels 2 are hung vertically on the front, rear, left and right of the rectangular underframe 1. Fixed intermediate wheels 3 having ground contact surfaces positioned slightly below the ground contact surface of the free wheel 2 are provided in front of and behind the middle of the left and right free wheels 2.

At the four corners on the front, rear, left and right of the rectangular underframe 1, a joint receiver 8 made of an aluminum alloy drawing material is hung vertically, and the lower end of the joint receiver 8 is closed at the lower end. A stacking locking portion 10 in which a rim 10 'to be fitted on the upper end of the supporting projection 9 of FIG. An L-shaped support protrusion 9 is continuously provided on the upper end of the joint receiver 8 to project on the rectangular frame 1, and a ladder body is provided inside the front and rear joint receivers 8 and 9 respectively. The joining means a is configured by being provided so that the columns 5 in front of and behind A can be fitted and inserted. (The illustrated joint receiver 8 and stacking locking portion 10
For convenience of manufacture, the joining female body 4 and the locking plate of the embodiment of claim 1
Formed in the same shape as 14. Note that reference numeral 12 is a bracket for firmly fixing the joint receiver 8 to the rectangular underframe 1.

Further, on the right and left sides of the rectangular base frame 1, there are provided grips 13 which are made of aluminum alloy drawn pipe material and whose surface is provided with anti-slip ridges.

Since this embodiment is constructed as described above, the supporting projections 9 on the front and rear and the right and left of the rectangular underframe 1 and the joint receiving body 8 are joined to the supporting columns 5 on the front and rear of the pair of left and right ladder bodies A by the joining means a. After inserting and inserting the lower end of the column 5 into contact with the upper surface of the locking portion 10 to jointly connect the pair of left and right ladder bodies A to the rectangular underframe 1 so as to face each other, the shelf plate 7 is attached to the left and right shelves. A shelf B is formed by being installed between the receiving bars 6.

When moving, the movable wheel 2 and the fixed intermediate wheel 3 as described above can be used to move on the spot using the fixed intermediate wheel 3 as a fulcrum. The traveling direction of the dolly can be changed.

When disassembling, the shelf 7 is attached to the left and right ladders A
When the shelf A and the ladder A are placed on the rectangular underframe 1, the rectangular underframe 1 is removed by removing the joining means a, pulling out the left and right ladders A from the underside frame 1, The upper erection part can be loaded low without being bulky.

Further, the stacking engaging portion 10 of the second carrier truck, in which the upper erection portion is loaded low as above, is stacked on the disassembled bearing protrusion 9 of the first carrier truck, and this work is carried out. Since it is possible to repeatedly stack many transport carts on the first transport cart, it becomes a transport cart that does not take up storage space.

Further, since the grips 13 formed of aluminum alloy drawn pipe material on the right and left sides of the rectangular underframe 2 and provided with anti-slip ridges on the surface are attached, it is convenient and easy to grip when moving and stacking is easy. Therefore, the disassembly and assembly becomes easier.

Further, since the base material of the carrier is formed of an aluminum alloy drawn-out long material having a hollow rectangular cross section, and the ridges are juxtaposed on the surface of this long material in the longitudinal direction, the weight is the same as that described above. It is a tough and easy-to-use carrier that is easy to handle, looks good, is suitable for mass production, and has low material and processing costs.

[0038]

As described above, according to the present invention, a pair of left and right ladder bodies are joined and erected on the rectangular underframe by joining means so as to face each other, and the left and right ridges are fitted to the height of the article to be placed. You can select shelf shelves and erect the shelves, so you can freely adjust the vertical spacing of the shelves that are erected in multiple stages, for example, according to the height of flowers, and remove the shelves. It is easy and at the time of movement, either the left or right free wheel 2 and the fixed intermediate wheel 3 are used to move the swivel truck in place. Since it can turn around 3 as a fulcrum, the traveling direction of the carrier can be changed even in a narrow place.

When not in use, the disassembled shelves and the left and right ladders can be placed and stored on the rectangular underframe, so that the upper erection portion of the carriage is not bulky and is stored low, so that the storage space is small. It becomes a carrier truck that does not take.

Also, by locking the stacking locking portion of the second disassembled transport trolley, which is loaded low as above, on the bearing protrusion of the disassembled first transport trolley, It is possible to stack a second carrier on the carrier and repeat this work to stack many carriers on the first carrier and move them to the desired location with the free wheels for storage. Therefore, it becomes a transporting trolley that can be stored compactly without taking up space.

Further, since the base material of the carrier is formed of a lightweight metal material such as aluminum alloy, disassembly / assembly work and movement of the carrier are easy.
