Abstract

PURPOSE:To provide a pallet leg having a structure in which the leg can be reliably and firmly fixed to a pallet base plate. CONSTITUTION:A pallet is provided with leg bodies 1 having an opening 2 and a bottom 12 at the upper and lower sides of the cylindrical side wall 11, a circular flange 3 provided at the periphery and extended outward from the nearby position of the upper edge of the opening 2 of the leg body 1, and a plurality of fitting protrusions 4 erected at specified intervels in the circumferential direction at a separated position outward from the opening upper edge 13, on the upper face of the circular flange 3. In this way, since the fitting protrusions 4 are attached to exclusive attaching holes 6, the fitting strength gets larger.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet leg for supporting a pallet substrate, and more particularly to a pallet leg having a structure capable of being securely locked to the pallet substrate.

[0002]

2. Description of the Related Art In recent years, a pallet substrate on which goods to be transported are placed,
The pallet legs that support the pallet substrate are made detachable, the pallet legs are attached and used during transportation, and the pallet legs are removed after the transportation is completed. ing. Conventionally, as a pallet leg for that purpose, the one shown in FIG. 5 has been known. That is, the pallet leg a includes a leg body 1a having an opening 2a and a bottom portion above and below a cylindrical side wall, and the leg body 1a.
The annular flange 3a is provided outwardly around the upper edge of the opening 2a downward by the thickness of the pallet board, and the locking tabs 4a are provided outward from the upper edge of the opening 2a at predetermined intervals in the circumferential direction. I am collecting. To attach the pallet leg a to the pallet base plate b, the pallet leg opening 2 is attached to the mounting hole 5b formed in the pallet base plate b with the same diameter as the outer periphery of the opening upper edge 2a.
a Insert the upper edge. At the time of this mounting, the mounting hole 5
A notch 6b for tab is connected to b, and the locking tab 4a is passed from the mounting hole 5b to the opposite side of the pallet board b, and the pallet leg a is rotated to mount the mounting hole 5b.
The peripheral wall is sandwiched between the annular flange 3a and the locking tab 4a and locked.

[0003]

The provision of the tab cutouts connected to the mounting holes in this manner is necessary for mounting the pallet legs on the pallet board, but when used for actual transportation. The tab notch itself is not preferable for the strength of the mounting hole peripheral wall, and therefore the mounting hole peripheral wall sometimes easily deforms due to the tab notch, which adversely affects the mounting strength of the pallet leg. It was In particular, like this transportation means, the pallet substrate is a cardboard or plastic plate, or one with a relatively simple structure such as wood chips that are pressed and solidified, and in many cases the one that does not have much strength is used, so the effect is extremely large. It was a thing.

The present invention has solved the above problems and provides a pallet leg that has a large attachment strength to a pallet substrate, has a simple structure, and is easy to handle.

[0005]

According to the present invention, there is provided a leg body having an opening and a bottom portion on the upper and lower sides of a tubular side wall portion, and an annular flange provided outwardly from the vicinity of the upper edge of the opening portion of the leg body. ,
A pallet leg is characterized in that a plurality of locking projections are provided upright on the upper surface of the annular flange at a predetermined distance in the circumferential direction outward from the upper edge of the opening.

[0006]

Since the pallet board has the above-mentioned structure, a plurality of locking holes are provided in the peripheral wall of the mounting hole in advance in the peripheral wall of the mounting hole at a predetermined distance from the inner edge of the pallet board at predetermined intervals in the circumferential direction. The pallet leg can be securely attached by aligning the upper edge of the opening of the pallet leg with the mounting hole and inserting the locking projection through the locking hole to fix the pallet leg.

Embodiments of the present invention will now be described in more detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIGS. 2, 3 and 4 are perspective views showing other embodiments of the present invention.

In FIG. 1, the pallet leg A of the present invention is
A leg body 1 having an opening portion 2 and a bottom portion 12 above and below a cylindrical side wall portion 11 having an upward spread, and an opening upper edge 13 of the leg body 1.
And an annular flange 3 which is provided outwardly from, and three locking protrusions 4 are provided upright on a concentric circle passing through the central portion on the upper surface of the annular flange 3 at intervals of 120 degrees. Locking protrusion 4
Has a standing piece portion 41 and a holding portion 42 from the tip of the standing piece portion 41 in parallel to the surface of the annular flange 3 in the same rotation direction on a concentric circle. The distance between the surface of the annular flange 3 and the holding portion 42 is substantially the same as the wall thickness of the peripheral wall of the mounting hole 5.

In order to attach the pallet leg A of the present invention to the pallet board B, the pallet board B is provided with a mounting hole 5 having substantially the same diameter as that of the upper edge 13 of the opening, and the holding portion 42 is provided on the peripheral wall of the mounting hole 5. Correspondingly, the locking hole 6 is provided. The mounting hole 5 and the locking hole 6 are separated from each other by a partition wall, and the mounting hole 5 is kept circular. The upper edge of the opening portion of the pallet leg A is aligned with the mounting hole 5, and the locking projection 4 is passed through the locking hole 6. When the locking tab 42 of the locking projection 4 passes through the locking hole 6 on the opposite side of the pallet board B, the pallet leg A is rotated toward the front end of the locking tab 42 so that the locking hole 6 The peripheral wall is sandwiched between the annular flange 3 and the locking tab 42 and locked. In this way, the pallet legs A need only be attached in the circumferential direction at predetermined intervals as required. Further, the number of the locking projections 4 of the pallet leg A and the number of the locking holes 6 of the pallet board B are not limited to three, and may be appropriately provided as needed, and the locking tab 42 has a corresponding annular flange 3. A through hole may be provided for die cutting during molding.

The pallet leg A of the present invention may be formed integrally with the locking projection 4 by injection molding of synthetic resin or the like.
Further, the pallet board B may also be formed into an appropriate size with synthetic resin, cardboard or the like.

In FIG. 2, the standing wall 14 is provided so as to extend upward from the opening upper edge 13 of the leg body 1, and the surface of the standing piece portion 43 of the locking projection 4 is provided in the direction along the standing wall 14 and the locking is performed. The tab 44 for use is provided outside the tip of the standing piece 41.
Correspondingly, a slit 61 continuous with the locking hole 6 of the pallet board B is provided in the rotation direction when the pallet leg A is attached.

In FIG. 3, the locking projection 4 is provided with a standing piece portion 45 and a lock portion 46 which rotates around the standing piece portion 45. The locking portion 46 is provided in the locking hole 6 of the pallet board B. It is attached by rotating it through 90 degrees.

In FIG. 4, a locking tab 49 for connecting the locking projection 4 to the standing piece 47 and the bending piece 47 via the hinge 48 is provided, and the locking tab 49 is provided. The locking hook 40 for locking the pallet is provided so that the pallet leg A can be attached to the pallet board B.

[0014]

Since the present invention is constructed as described above, it is possible to obtain a pallet leg which has a large attachment strength to a pallet board, has a simple structure, and is easy to handle.
