Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column provided around the periphery of a pallet that conveys a long product such as an extruded profile.

[0002]

2. Description of the Related Art Conventionally, this kind of pallet is actually fair
As described in Japanese Patent No. 44886, the columns can be tilted during the work of placing the loaded materials on the pallets or when the pallets are piled up in a warehouse or the like.
The prop is constructed so that it can be erected when the material to be loaded is loaded and conveyed, and the means according to the above publication does not allow the prop to stand up and down with a hinge, and the core block provided in the prop is erected from the pallet body. It is configured so that it can rush into the base material and be held upright.

[0003]

According to the above-mentioned prior art, when the left and right props are folded and folded, the left and right hinges are mounted so that the left and right props vertically overlap with each other in a horizontal state. Since the height of the base material is different, it is necessary to lengthen one of the columns because of the different mounting means, which causes a difference in the swallowing amount of the core block into the base material, and the length is long. Since the amount of drinking is small on the pillar side, the standing holding force of the pillar is weakened. However, in the case of this publication, since a horizontal crosspiece is provided between the left and right columns, this is not a serious problem, but it is a problem when each column is erected independently.

Further, if it is attached with a hinge, the columns cannot be easily exchanged, and when carrying a pallet for carrying a large number of loaded materials, or depending on the loaded materials, Sometimes only a small amount can be loaded,
Moreover, since multiple pallets can be stacked vertically when carrying, if the height of the pillar is constant, both the one with a small amount of material to be loaded and the one with a large amount of material will have the same height. Therefore, a small load is disadvantageous for transportation.

The present invention is to solve the above-mentioned problems, and it is an object of the present invention to make it possible to erect, fold, and fold the strut in the same manner as in the prior art, and to make it removable so that the strut can be replaced. To provide as.

[0006]

A first means for solving the problems according to the present invention is a column for a transportation pallet, in which a column portion is inserted and removed and is tiltably fitted into a socket standing on the outer peripheral edge of the pallet. One of the front and rear surfaces of the socket facing the longitudinal direction of the pallet is formed into a long wall, and the other is formed into a short wall shorter than the height of the long wall, and a stopper is provided in the socket between the long wall and a portion above the short wall. Elongated holes that are provided at intervals and into which the stoppers project are provided along the longitudinal direction from the lower end of the pillars, and between the stoppers and the long walls between the lower ends of the elongated holes of the pillars and the lower ends of the pillars. It is characterized in that it is provided with an engaging portion capable of passing through the gap.

A second means for solving the problem is a column for a transportation pallet in which a column portion is inserted into and removed from and tilted into a socket that stands on the outer peripheral edge of the pallet, and is directed toward the longitudinal direction side of the pallet in the socket. One of the front and rear surfaces is formed as a long wall and the other is formed as a short wall that is shorter than the height of the long wall, and is formed with a vertical width smaller than the horizontal width at each lower end of both standing walls of one of the pillar portions facing each other. Protrusion-shaped engaging portions are provided such that their long sides are orthogonal to the longitudinal direction of the column portion, and concave grooves extending from the upper end to the lower end are formed on the inner surfaces of both upstanding walls that intersect the long and short walls of the socket. The width of the groove is smaller than the width of the groove and larger than the width of the groove, and the groove width is continuous and stepwise between the short wall side of the groove and the lower end of the groove higher than the upper end of the short wall. A wider guide groove is provided, and the stepped portion is used as a stop portion.

[0008]

When the pillar portion according to the above-mentioned first solution is fitted into the socket, the pillar portion is laid sideways with the long hole thereof facing down, and the lower end portion thereof is inserted into the socket from the upper portion on the short wall side. When it is inserted deeply and lowered horizontally as it is, the stopper portion in the socket fits into the elongated hole, and the engaging portion of the column portion passes through the gap between the stopper portion and the long wall. Then, the pillar portion is erected in the socket and is erected and held by being inserted deeply into the socket.

When tilting the standing pillar, if the pillar is pulled up while standing, the engaging portion of the pillar hits the stop, and at that point the pillar is tilted toward the short wall side. Can be defeated.

When the pillar portion is pulled out, the pillar portion is supported substantially horizontally from the tilted state as described above and pressed against the long wall so that the engaging portion of the pillar portion causes the gap between the stopper portion and the long wall. It can be pulled out by pulling up the column part as it is.

The case of the second solving means is almost the same as the above-mentioned solving means, but when the pillar portion is fitted into the socket, the pillar portion is laid sideways and both engaging portions are fitted into the recessed grooves of the socket. After being inserted deeply into the socket, the pillar portion is erected, and then the pillar portion is further inserted into the socket so that the pillar portion is held upright.

At the time of tilting, by pulling up the standing pillar portion, the engaging portion of the pillar portion abuts on the stopper portion in the socket. Therefore, by tilting the pillar portion as it is, the engaging portion contacts the stopper portion. It is tilted while touching.

At the time of withdrawing, if the tilted column portion is pushed into the socket toward the long wall thereof, the engaging portion of the column portion faces the concave groove, so that the column portion can be pulled out as it is and pulled out. it can.
