Description

[Detailed Description of the Invention] The present invention relates to an aluminum pallet.
This invention relates to a pallet that facilitates assembly.

Metal pallets are being used to replace wooden pallets.

For example, the pallet a seen in Utility Model Publication No. 5426 shown in Fig. 1 has holes 61 drilled in the horizontal pieces C on both sides of the deck board b, and holes g bored in the upper and lower pieces f of the legs e. A bolt h is passed through and nuts i are fastened to both ends of the bolt to fix the deck board b and the leg e.

In addition, the pallet a' shown in Fig. 2 and shown in Japanese Utility Model Publication No. 42-2181 has holes d' drilled in the valleys of a deck board b' having a plurality of consecutive peaks, and a hole d' drilled in the earthen wall of the leg e'. Drill a hole corresponding to the hole d' of the deck board b' and align both holes "9g", then pass the bolt h' from above and tighten the nut i' on the leg side to connect the deck board b' and the bottom. ′ is fixed.

In these known pallets, (a) bolt insertion holes are provided in the deck board and the legs, respectively, and when the deck board and the legs are fixed, it is necessary to align both holes.

(b) After aligning both holes, it is necessary to pass the bolt through and tighten it by applying a tool such as a spanner to both ends of the bolt.

However, in (a) above, the relative position of the deck board to the leg is fixed, making it impossible to adjust the relative position between the two, and the tolerance between the holes drilled in the deck board and the leg is large. In this case, it is not possible to secure both parts, and it is necessary to increase the precision of the work to maintain the safety.In addition, regarding (b) above, in the example shown in Figure 2, special fasteners that pass through the hollow legs are required. There are deficiencies such as the need for additional tools.

This idea was intended to eliminate the above-mentioned problems with conventional pallets, and basically consists of a groove in the upper part of the leg, in which a bolt head or nut is placed in a non-rotatable manner. , using technical means to easily fix the two while allowing the relative position of the deck board to the legs to be adjusted.

According to this invention, in an aluminum pallet consisting of a plurality of deck boards and legs, holes are provided in the portions of the deck boards in contact with the legs, through which the threaded portions of bolts pass, and further, holes are provided in the upper portions of the legs. The head of the bolt or the nut is slid along the longitudinal direction of the dovetail groove in a dovetail groove provided along its longitudinal direction, but is accommodated in a non-rotatable manner with respect to the dovetail groove, and the nut and the hole of the deck board There is provided a pallet characterized in that the deck board and the legs are fixed by fastening the bolts that pass through them.

An embodiment of this invention will be described with reference to the accompanying drawings.

The pallet 1 has a plurality of legs 3 spaced apart from each other,
A plurality of deck boards 2 are fixed at right angles to the longitudinal direction (see FIG. 3).

FIG. 4 shows an example of how the legs 3 and the deck board 2 are attached.

The deck board 2 is made of an aluminum profile with a hat-shaped cross section, and flanges 4, 4 extending in the longitudinal direction are provided at the lower edges on both sides.
The flanges 4, 4 are provided with a hole 4' through which the threaded portion of the bolt 5 passes.

The leg 3 is made of a hollow aluminum member, and the flange 4 of the deck board 2 is seated on the horizontal surface 8 of the upper wall thereof.

A dovetail groove 9 in which the opening 11 is narrower than the bottom is integrally formed in the center of the horizontal surface 3 in the longitudinal direction.

The width of the lower part 10 of this dovetail groove 9 is such that the head 6 or nut 7 of the bolt 5 can move in the longitudinal direction but cannot rotate.
1 is formed to have a width that allows only the threaded portion of the bolt 5 to be inserted therethrough.

Fig. 4 shows the case where the head 6 of the bolt 5 is inserted into the dovetail groove 9, but when inserting the nut 7 into the dovetail groove, the dovetail groove allows the tip of the threaded part of the bolt 5 to enter. It is better to make the bottom 10 of 9 deep.

Regarding the assembly of the above structure, the head 6 of the bolt 5 is inserted into the groove 9, and then the threaded portion of the bolt 5 is passed through the hole 4' formed in the horizontal flange 4 of the deck board 2.

After selecting the position of the deck board 2 relative to the leg 3, the nut 7 is tightened to fix the leg 3 and the deck board 2.

Incidentally, as shown in FIG. 5, the deck board 2 may have a shape in which the peak portions 12 and the valley portions 13 are continuous.

In this case, a hole 4' is bored in the trough 13, and the bolt 5 is screwed into the nut 7, which is non-rotatably inserted into the groove 9 of the leg 3, through the hole 4' in the trough 13.

Since the head 6 of the bolt 5 enters the valley part 13 and is surrounded by the peak part 12, the head 6 does not come out from the upper surface of the deck board 2.

As described above, the present invention has the advantage that the position of the deck board 2 relative to the legs 3 can be arbitrarily selected.

Furthermore, by providing the lower wall with the same structure as the earthen wall of the legs, it is also possible to attach deck boards to both sides.

These configurations can be easily formed by extrusion.

Since the legs and the deck board are fastened together using bolts, the attachment is strong, and the deck board can be easily removed and replaced by removing the bolts and nuts.
