Abstract

PURPOSE:To provide a pallet with casters, having a simple structure, in which the casters can be positioned to contact the ground or float against it. CONSTITUTION:Casters 2 are fixed to the lower side near the four corners of the top plate 1 forming a rectangular pallet body in plan view and vertically movable plates 6 which make the casters float, between the upper side position than the lower end of the casters and the lower side position, are provided below the top plate 1. And a cam 5 fixed to an axis 4 and rotated is positioned to contact the upper end of the plate 6 in order to move up and down the plate 6 making the caster float.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet with casters for carrying and moving loads.

[0002]

2. Description of the Related Art As a conventional pallet with casters of this type, for example, the one disclosed in Japanese Utility Model Publication No. 4-89737 is known.

The pallet with casters disclosed in Japanese Utility Model Laid-Open No. 4-89737 has a box-like pallet for loading luggage, and a trolley with a caster for movement fitted inside the box-like pallet. A moving piece that is sandwiched between the bottom surface of the box-shaped pallet and the upper surface of the trolley, and a moving piece moving means that removes or re-sandwiches the moving piece are provided. The box-shaped pallet is stably installed on the ground by floating the casters from the ground, and when the luggage is moved, the moving piece is sandwiched so that the casters protrude from the box-shaped pallet and are in contact with the ground. There is.

[0004]

Therefore, in this conventional pallet structure with casters, the box-shaped pallet and the trolley are made separately, and the casters come into contact with or float on the ground. By doing so, in order to make the casters protrude or retract from the box-shaped pallet, the moving piece is removed or pinched by the moving means between the bottom surface of the box-shaped pallet and the top surface of the trolley. However, there is a problem that the structure of the entire pallet becomes complicated and the cost becomes high.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a pallet with casters which has a simple structure and allows the casters to come into contact with or float on the ground.

[0006]

In order to solve this problem, according to the present invention, casters are attached to the lower side of at least a corner portion of a pallet body having a rectangular planar shape, and the caster is attached to the lower side of the pallet body. The gist of the present invention is to provide a floating plate that can move up and down between a position above and below the lower end of the caster, and to provide means for moving the floating plate up and down.

[0007]

With this structure, it is possible to provide an inexpensive pallet with casters, which has a simpler structure for contacting or floating the casters with respect to the ground than the conventional one.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 5, reference numeral 1 denotes a top plate having a rectangular planar shape made of a veneer plate or the like forming a pallet body, and casters 2 are attached to the lower side of the top plate 1 near four corners. Reference numeral 3 denotes a long cam storage box that is mounted in parallel to each other on the lower surface of the top plate 1 between the mounting positions of the casters 2, and a shaft 4 is horizontally penetrated and supported in each cam storage box 3. ,
Inside the cam storage box 3, cams 5 are attached near both ends of the shaft 4. 6 is each cam storage box 3
Is a floating plate provided over substantially the entire length of the cam storage box 3 so as to project from the lower surface of the cam storage box 3, and the upper ends of the convex portions 7 provided at the upper ends of the floating plates 6 of the respective cam storage boxes 3 in the longitudinal direction are the cams. 5 is abutted. Reference numeral 8 denotes a spring provided in the cam storage box 3 at a position sandwiching the shaft 4 near the mounting position of the cam 5 for urging the floating plate 6 upward. The lower end of each spring 8 is at the cam storage box 3 The bottom end of the washer 11 is in contact with the upper surface of the bottom part of the base plate, and the upper end thereof is in contact with a washer 11 held by a nut 10 which is erected on the floating plate 6 and which is screwed onto the upper end of a pin 9 penetrating the spring 8. The lower end of the caster 2 projects slightly from the lower surface of the floating plate 6 when the floating plate 6 is located at the uppermost position, and is located slightly above the lower surface of the floating plate 6 when the floating plate 6 is located at the lowermost position. Is configured to.

In the above structure, when the pallet is lowered to the ground and moved, the shaft 4 is rotated by an appropriate jig from the end of the shaft 4 which horizontally penetrates the cam storage box 3 to move the cam 5 laterally. The floating plate 6 is moved upward by the force of the spring 8 by moving it to the uppermost position, so that the lower end of the caster 2 is slightly projected from the lower surface of the floating plate 6, and the caster 2 is placed on the ground. The pallet can be moved on the ground.

When the casters 2 are unnecessary for stacking a large number of pallets, the shafts 4 are rotated from the end of the shaft 4 by an appropriate jig to erect the cams 5 to raise the floating plates. 6 moves downward and is located at the lowermost position, and when the floating plates 6 contact the ground, the lower end of the caster 2 is positioned slightly above the lower surface of the floating plate 6 and cannot be moved by the casters 2. .

In the embodiment described above, the floating plate 6 is operated by the cam 5 attached to the shaft 4, but it may be operated by other driving means such as a jack. .

Further, when the pallet is lifted by a forklift, a fork may be inserted between the cam storage boxes 3 and 3 attached to the lower surface of the top plate 1 to lift the pallet.

[0013]

As described above, according to the present invention, it is possible to provide a pallet with casters, which has a simpler structure for contacting or floating casters with respect to the ground than the conventional one, and is inexpensive. it can.
