Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable transport pallet, and more particularly, to a foldable transport pallet in which columns are freely foldable in the vertical direction and a floor plate can be expanded and contracted left and right.

[0002]

2. Description of the Related Art When materials and parts are carried into an automobile factory or an electric appliance assembly factory, generally, they are framed by a plate-like or rod-like wood, and mounted on a truck to be carried in. However, the timber after it has been brought in is discarded as it is. However, this results in the disposal of timber that has only been used once, leading to a waste of resources, which is by no means preferable from the perspective of the global environment.

Therefore, conventionally, there has been proposed a transportation pallet for the purpose of mounting parts or materials in a factory.
For example, we propose a transport pallet that can be repeatedly used by arranging a large diameter metal hollow pipe at the bottom and arranging a thin pipe in the shape of a pole on top of it, which can be expanded and contracted up and down. Has been done. However, such a metal pole is heavy, and the work of inserting and removing four metal poles is extremely troublesome, and there is a possibility that the extracted pole may be lost.

[0004]

Therefore, the present invention is intended to develop a transfer pallet suitable for mounting parts or materials in such a factory, and in particular, it can be easily folded in the vertical direction. The purpose of the present invention is to create a transfer pallet and a transfer pallet whose width can be adjusted in the horizontal direction.

[0005]

SUMMARY OF THE INVENTION A folding transfer pallet according to the present invention comprises a mounting base on which a floor member formed of a square pipe is stretched, a root post fixed to a corner of the mounting base, and a top thereof. In addition, the lower column body and the upper column body are composed of a column portion that is erected so as to be foldable in two stages via a folding portion and a folding portion. The folding portion is formed by rotatably forming a lower columnar body along a vertical groove around an axis of rotation that is arranged in a part of the root columnar body, and is fitted into the head of the root columnar body. The claw pieces of the lower column are fitted and fixed in the grooves. The folded-back portion is formed so as to be freely rotatable by interposing a hinge between the lower column body and the upper column body, and has a U-shaped stopper that is slid while being held by the upper column body while being held by the holding frame. A back support plate, which is mounted and forms a groove space into which the stopper can be inserted, is arranged by surrounding three sides of the lower column.

[0006] In the second aspect, a lateral slide portion capable of expanding the floor area in the lateral width direction is added to the configuration of the above invention. The lateral slide portion inserts a slide floor member formed of a round pipe into the floor member of the rectangular pipe, connects the slide floor members with each other by a connecting rod, and forms a hooking groove in parallel with the slide floor member. It is configured by providing a hooking member that is bored, and attaching a fastener for fixing the hooking member to a part of the floor member so as to be rotatable.

[0007]

[Operation] When the lower column of the folded portion is vertically rotated and lowered along the vertical groove, and the claw piece is fitted into the fitting groove, the folded lower column is fixed upright and fixed on the floor. The load loaded on the member is supported in the vertical direction.

Then, when the upper column of the folded portion is vertically rotated, the upper column is erected, and when the U-shaped stopper is held down by the frame and is slid downward, the lower column is formed. It is inserted into the groove space of the column, and it is supported and fixed by the backing plate that surrounds the three sides of the column, exerting strong physical strength in the front and rear and left and right directions, and loads that are even higher loaded on the floor member. It supports and is easy to fold back, and also has a large supporting strength.

Further, by sliding the sliding floor member laterally, the floor area can be expanded and at the same time, the L-shaped fastener is rotated so that its head is engaged with the engaging groove of the engaging member and the adjacent receiving piece. By doing so, the slide member can be fixed in multiple stages, and the floor area can be freely changed and adapted according to the shape and size of the luggage.

That is, the lower column body 22 is rotatable with respect to the root column body 21 about the rotation support shaft 24a, and when the lower column body 22 is erected, the lower column body 22 is rotated vertically. ,
The claw piece 24 of the lower column 22 is lowered along the vertical groove 24b.
The structure is such that d can be fitted into the fitting groove 24c and fixed.

Next, the lower columnar body 22 and the upper columnar body 23 are connected to the root columnar body 21 in series to form the columnar portion 20. The columnar body is formed by a square pipe, and its length is loaded. The lower column 22 is, for example, about 80 cm, and the upper column 23 has a length that does not reach the lowermost side of the mounting table 10 when folded at a folding section 25, which will be described later.

The folding section 25 is, as shown in FIGS. 3 and 4,
A hinge 25a is attached between the lower column body 22 and the upper column body 23 so that the upper column body 23 can be folded back to the outside. A U-shaped stopper -25c is provided which is vertically slidable along the column. On the other hand, on the lower column body 22 side, a back contact plate 25f surrounding three sides of the column body is provided with the stopper 25c.
Is formed while forming a U-shaped groove space 25g into which the slot can be inserted. Incidentally, 25d is a receiving piece provided at the upper end of the stopper 25c.

That is, the lower column body 22 and the upper column body 23 can be folded back through the hinge 25a, and the upper column body 23 can be folded back.
When standing up, the upper column 23 is rotated right above the lower column 22, and the stopper 25c is attached to the back support plate 25 of the lower column 22.
It is inserted and fixed in a U-shaped groove space 25g formed by being surrounded by f so that the standing posture can be maintained even when a load is applied to the upper column 23 from the front or rear or the left and right.

Further, the horizontal slide portion 30 is inserted into the floor member 13 of the square hollow pipe, and the same number of slide floor members 31 as the floor members 13 are arranged by using a round pipe. The height is within about 1/2 of the floor member 13,
Separate on the left and right. The connecting rods 32 are arranged on the left and right with L-shaped angles, and the edge portion 33 is formed on them by a round pipe. Then, as shown in FIG. 5, a latching member 34 is fixed to the connecting rod 32 at a substantially central portion thereof in parallel with the slide floor member 31, and a latching groove 34a is formed in several stages of the latching member 34. To do. On the other hand, a bearing 35 is arranged to be fixed to the floor member 13, an L-shaped bent metal fitting 36 is rotatably attached to the floor member 13, and the metal fitting 36 is locked on the vertical frame 12. For this purpose, the receiving piece 37 for arranging the retaining member 34 is arranged. Incidentally, 3
Reference numeral 4b is a drop-out preventing piece for preventing the hooking member 34 from falling off.

Next, the method of use of the present embodiment will be described. First, when loading an assembly part of an automobile and an electric product, etc., when the transportation pallet in a folded state is opened, the floor is adjusted according to its size. The sliding floor member 31 mounted in the member 13 is slid laterally to expand the floor area. While grasping and pulling out the edge portion 33 of one of the left and right round pipes, at that time, with respect to the square floor member 13,
Since the slide floor member 31 is formed in a round shape, the frictional resistance is small and the withdrawal and insertion can be easily performed only by making four or three points of contact.

When the length reaches the predetermined length, the L-shaped fastener 36 is rotated so that the head portion thereof is engaged with the engaging groove 34a of the engaging member 34 and the adjoining receiving piece 37, and the slide floor member 31. To fix. Similarly, one of the left and right slide floor members 31 is pulled out. At this time, the fixed position may be the same as or different from the previous position, and is appropriately selected according to the shape and size of the luggage. As a result, the area of the floorboard is expanded in multiple stages, and it is possible to freely adapt to the form of luggage.

Next, the height adjustment is started, and first, with respect to the fixed root pillar body 21, the lower stage pillar body 22 is rotated upward about the rotation support shaft 24a of the folding portion 24 as a vertical state. After that, it is lowered along the vertical groove 24b, and the claw pieces 24 of the lower column 22 are
d is fitted and fixed in the fitting groove 24c (see FIGS. 6 and 7). As a result, the folding portion 24 is firmly fixed, the lower column body 22 is vertically erected, and four columns stand around the floor member 13, so that the height of the column body depends on the size and the number of loads to be loaded. Can be adapted.

Further, when the load is increased upward, or when the load is high, the upper column 23 is rotated upward about the hinge 25a so as to stand on the lower column 22, and , The stopper 25c is slid downward while being held by the holding frame 25b, inserted into the U-shaped groove space 25g formed between the lower column 22 and the back support plate 25f, and finally the stopper 25c The receiving piece 25d is locked and fixed to the upper edge of the holding frame 25b. Then, the lower column body 22 and the upper column body 23
When the and column are erected in series and a load for folding the upper column 23 is applied, the stopper 25c inserted across the lower column 22 and the upper column 23 is placed on the backrest. Since it is restrained by the plate 25f and the restraint frame 25b, it can strongly resist the load, and since it is formed in a U shape and surrounds the three sides of the lower stage column body 22 and the upper stage column body 23, it is forward and backward to the column body. It can strongly resist not only the load in the direction but also the load in the diagonal direction (see FIGS. 3 and 4). As a result, the lower column body 22 and the upper column body 23 exhibit a strong physical strength in the front-rear direction and the left-right direction when they are erected while having the convenience of folding height adjustment. The folding can be performed by a simple operation of only moving the stopper 25c up and down (see FIGS. 8 and 9).

When the slide floor member 31 has been expanded in the width direction, the L-shaped fastener 36 is rotated to remove it from the hooking member 34, and the round slide floor member 31 is a square pipe floor member. Store in 13 and return to the original short rectangle.

After the upper column 23 is erected, if necessary, the load is bundled with a string or the like to complete the loading, and the claws of the forklift are inserted into the voids 15 of the mounting table 10 and loaded into the transport vehicle. Transport (see Figure 10).

At the time of this loading, in the case of a mode in which only the lower column 22 is erected by folding the upper column 23 of the column,
Fit the head of the lower column 22 into the recess of the mounting table 10,
It can be stacked on the 2nd and 3rd floors and can be efficiently mounted on a vehicle (see FIG. 11).

As described above, when the cargo is carried by being loaded on the carrying pallet of the present invention and the unloading is completed, the pallet is folded and brought back, and the upper column 23 is first erected. In this case, the receiving piece 25d of the stopper 25c of the folding portion 25 is picked up and slid upward, and lifted up to the position of the stop piece 25e. Then, the upper column 23 is centered around the hinge 25a.
When the stopper 25c is folded back down and placed along the lower columnar body 22, the stopper 25c remains in the stopper piece 25e and can be folded back.

Further, when the folding portion 24 between the mounting table 10 and the lower column 22 is folded, the lower column 22 is lifted right above and then rotated so that the claw piece 24d is fitted into the fitting groove 24c. Remove from
The lower columnar body 22 is rotated and folded around the rotation support shaft 24a. As a result, the columnar body includes the upper columnar body 23 and the lower columnar body 22 that are folded together, and when these are vertically stacked and mounted on a vehicle, the columnar body is not bulky and is extremely compact, as shown in FIG. 12 and FIG. It is convenient for transportation.

[0028]

As described above, according to the present invention, the height of the pillar can be changed in two steps according to the size and quantity of the load, and the folding work can be stopped by the stopper. It has an excellent effect that it can be operated simply by moving the − up and down, and the physical strength of the folded portion also exerts strength in the front, back, left and right directions. By expanding and contracting the slide portion in the lateral direction as well, the dimensions can be changed according to the shape of the load, the size of the transport vehicle, etc., and the loading efficiency is greatly improved.
