Description

[Detailed explanation of the idea] This invention relates to a cargo handling pallet.

Conventionally, for this kind of pallet, a board material is brought into contact with the connecting part of a girder material having a connecting part having a C-shaped groove in cross section at the end of the girder body, and a screw passing through the board material is inserted into the connecting part as described above. A structure in which the nut is screwed onto a nut inserted into a C-shaped groove is known.

However, this conventional pallet has the disadvantage that when the screws and nuts are loosened, the board material shifts in the longitudinal direction of the girder material and easily comes off from the girder material.

The present invention eliminates the drawbacks of the conventional pallet, and provides a pallet having a connecting part for the above-mentioned nut such that an integral or separate stopper is always engaged with a notch provided in the flange of the C-shaped groove of the girder body. , Examples thereof will be described below with reference to the drawings.

In Fig. 1, the girder material 1 connects the board material connecting parts 3, 3' having grooves 4 with a substantially rectangular C-shaped cross section on both the upper and lower ends of the girder main body 2, with the grooves 5 of the connecting parts 3 upward. The grooves 5 of the portions 3' are respectively provided facing downward, and the three girder members 1 having such a structure are positioned in parallel with appropriate intervals, and each girder member 1. A large number of board materials 6 are provided on the upper surface of the connecting portion 3 and the lower surface of the connecting portion 3'.
... and 6'... are connected, respectively.

For convenience, the connection between one connecting portion 3 and the board material 6 will be described.

As shown in FIG. 4, left and right flange portions 7, 7 facing each other across the groove 5 of the C-shaped groove 4 are provided with a pair of rectangular left and right notches 8, 8 facing each other. (In the figure, two pairs of notches are provided for connecting one board material.)

On the other hand, a nut 9 having a screw hole 10 formed in a rectangular plate is inserted into the C-shaped groove 4 as shown in the sixth figure, and a nut 9 is inserted into the pair of notches 8, 8 as shown in the fifth figure. A stopper 11 with a screw hole 12 formed in a rectangular plate is positioned at , and a screw 13 is inserted through the board material 6 from above as shown in the second figure.
passes through the stopper 11 and is screwed into the nut 9.

In this case, the rectangular plate-shaped nut 9 has such a shape and dimensions that it does not come out of the pair of notches 8, 8 when it hits the flanges 7, 7, and cannot rotate within the C-shaped groove 4. The stopper 11 has such a shape that it is engaged in the pair of notches 8 and cannot be moved in the longitudinal direction of the beam member, and has a thickness that is equal to or thinner than the thickness of the flange portion 7.

When the screw 19 is tightly screwed into the nut 9, the board material 6
The flange portion 7.7 of the beam member 1 is fastened between the lower surface and the nut 9, and the beam member 1 and the board member 6 are connected.

Even if the screw 13 and nut 9 are loosened, the stopper 11 engages within the pair of notches 8 and 8 to prevent the bonded material 6 from shifting in the longitudinal direction of the girder. , 8.

In the connection operation, first insert the nut 9 into the C-shaped groove 4 of the beam member 1, position it below the notches 8, 8, and then insert the stopper 11 into the nut 9 through the notches 8, 8. drop it on top.

In this state, place the board material 6 on the connecting part 3, and pass the screw 13 through the board material 6 from above and from the groove 5 to C.
It is suspended in the shaped groove 4, passes through the stopper 11, and is screwed into the nut 9.

When the screw 13 is screwed in, the nut 9 rises, so that the stopper 11 engages in the pair of notches 8.8.

Alternatively, the stopper 11 may be inserted in advance into the screw 13 penetrating the board material, the nut 9 may be loosely screwed together, and the stopper and nut portion may be inserted into the C-shaped groove 4 from the end to connect. .

In the other embodiment shown in FIG. 7, the inner surfaces of the pair of notches 8, 8 (in this example, the left and right inner surfaces) are appropriately inclined so that the stopper receiver is formed in the portions 14 and 14, and the outer surface of the stopper 11 is In this example, the side surfaces (in this example, the left and right outer surfaces) are also formed with inclined hooks corresponding to portions 14.14 and 15.15, and other structures are substantially the same as those in FIGS. 1 to 6, The notch 8, without dropping the stopper 11 into the C-shaped groove 4 during the connection operation.
This means that it can be easily installed in the correct position within 8.

In yet another embodiment shown in FIG. 8, the depth of the C-shaped groove 4 is made shallow enough to allow the nut 9 to slide, and the auxiliary groove is narrow enough to allow the tip of the screw 13 to penetrate into the bottom of the C-shaped groove 4. 16, and the other structures are substantially the same as those in FIGS. 1 to 6.

In this example, when the stopper 11 is cut and inserted into the main parts 8, 8 during the connection operation, the stopper is placed in the correct position on the nut 9.

In another embodiment shown in FIG. 9, the nut 9 and the stopper 11 are integrally formed, and the lower surface of the nut 9 is made of sponge, rubber, etc.
This is an example in which mohair or other elastic material 17 is attached, the C-shaped groove 4 is deep enough to allow the above-mentioned integral part to slide, and the other structures are substantially the same as those in Figs. 1 to 6. In operation, the integral nut 9 and stopper 11 is inserted into the C-shaped groove 4 from the open end surface while compressing its elastic material 17, and when the stopper 11 reaches just below the pair of notches 8, 8. The resilient force of the elastic member 17 allows the stopper 11 to be automatically engaged in the notches 8, 8, and the screw 13 can be inserted easily.

In some cases, a material other than the elastic material 17 may be used.

In any of the above examples, the notches 8, 8 and the stopper 11 are not limited to rectangular shapes, but may have various other shapes.

According to the pallet of this invention, even if the threaded connection between the screw and the nut becomes loose, as long as the stopper is engaged in the pair of notches, the board material is prevented from shifting in the longitudinal direction of the girder material,
It can prevent it from coming off from the girder material,
Therefore, it is extremely effective in practical use, such as ensuring work safety.
