DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin pallet used for storing and transporting luggage, and more particularly to a synthetic resin pallet having a card holding portion capable of detachably holding a card on a side surface. .

[0002]

2. Description of the Related Art A pallet integrally formed with a card holder is used for a synthetic resin pallet in order to attach a card indicating the name of the product to be loaded, the quantity, the number of the pallet, or the name of the company that owns the pallet. Have been. For example, in a synthetic resin pallet described in Japanese Utility Model Publication No. 6-2907, as shown in FIGS. 10 and 11, a concave portion 1 is formed on an outer surface of a spar facing a card holding portion 7 in a fork insertion direction.
Forming an upper end convex portion 2 and a lower end convex portion 3, an upper slit 2 a penetrating through the upper and lower surfaces of the upper end convex portion 2, and the lower end convex portion 3 has an open upper surface and a bottomed bottom. It is characterized in that it is formed by providing a lower slit 3a. The card to be used is inserted from the upper slit 2a, and the lower end of the card is inserted into the lower slit 3a so as to be detachably held.

On the other hand, there are two methods of manufacturing a synthetic resin pallet, namely, an integral molding method using an injection molding machine, and a butt welding method in which the divided surfaces of previously divided parts are integrally formed by butt welding. There is a molding method. Furthermore, the latter method of dividing the pallet in the butt welding method includes a dividing line 4 parallel to the side surface of the pallet.
(See FIG. 10)
A method of dividing a pallet into upper and lower parts at a girder part by a dividing line 5 parallel to the loading surface of the load (see FIG. 12).
There is. And when forming the card holding part 7,
In the integral molding method or the method of dividing the pallet in parallel with the side surface of the pallet, no bead is generated in the card holding portion by welding, so that the bead does not hinder the attachment / detachment of the card (see FIG. 11).

[0004]

However, in the method of dividing the pallet in parallel to the loading surface of the load, the card holding portion 7 is also formed by butting and welding two upper and lower parts. Butt welding surface exists inside, and beads are generated (see FIG. 12). Therefore, there is a problem that the card cannot be smoothly attached or detached by hitting the bead when the card is inserted or removed. The width of the slit for inserting the card is preferably as small as possible to prevent the card from being accidentally dropped. However, the narrower the width, the more difficult the molding becomes.
Furthermore, when taking out the card, the card cannot be picked up from above, and the card must be pushed up from the bottom to protrude the upper end of the card from the loading surface and then pulled out, so that taking out the card is troublesome. The present invention has been made in view of such a situation, and provides a synthetic resin pallet as a card holding portion that allows easy insertion and removal of a card and prevents swelling into a slit for inserting a card even when a bead occurs. The purpose is to provide.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a plan view of a synthetic resin pallet according to the present invention, and FIG. 2 is a front view of the same. The synthetic resin pallet 10 is in the short direction (depth direction)
A large pallet having a dimension of X of 1160 mm and a dimension of Y in the longitudinal direction (frontage direction) of 2000 mm.
They are connected by a center girder 16 and a middle girder 17. The end girder 15, center girder 16 and middle girder 17
Is a two-sided pallet provided in parallel with the side surface in the transverse direction X and having a fork insertion hole 18 between the center girder 16 and the middle girder 17. Since the pallet 10 is a large pallet having the above dimensions, the pallet 10 is configured so that it can be used as a guarded pallet 10 to which a side guard is attached in order to prevent the load loaded on the loading surface from dropping. Have been. Therefore, between the both end girder 15 and the middle girder 17, there is a column storage hole 19 for storing a column serving as a guide member, and like the fork insertion hole 18, the column storage hole 19 is opened on the opposite side.

[0007] The synthetic resin pallet 10 is formed by a butt welding molding method in which a plurality of parts formed in advance by division are welded and integrally assembled. That is, as shown in FIG. 1, two parts 24 and 26 are divided and formed by a dividing line 22 which passes through a substantially central portion in a plane and is parallel to a side surface, and these parts are further formed as shown in FIG. The upper part 24a, 2
6a and the lower parts 24b and 26b are divided and molded into a total of four parts. The upper part 24a, 26a and the lower part 2
Reinforcing ribs are provided vertically and horizontally on the inner surfaces of 4b and 26b.

Further, the synthetic resin pallet 10 is provided with card holding portions 31 which are features of the present invention on both sides of the dividing line 22. The card holding portion 31 includes a rear wall for holding a card to be inserted, a U-shaped side end frame and a lower end frame, and an inclined portion is formed at an upper portion of the rear wall, and a drain hole is formed at a bottom portion. Is provided. The card holder 31 provided on the component 26 is
4 has the same structure as the card holding unit 31 of FIG.
Will be described. The component 24a includes a rear wall 34a, a side wall 35a, and a side end frame 36.
A slit 37a for inserting a card opened on the upper surface of the upper deck board 11 is formed by a. Rear wall 34
“a” has an inclined portion 39 at the center in the height direction, and has a notch 38 at the lower end by cutting out a ridge on the side of the side end frame 36a. Further, in the illustrated example, the side end frame 36a is provided only at the lower part of the notch in the upper part of the component 24a, and therefore, the upper part of the slit 37a is also open in the front.

On the other hand, the component 24b has a rear wall 34b,
A slit 37b is formed by the side wall 35b, the side end frame 36b, and the lower end frame 40. A mounting portion 41 for mounting a card integrally with the side wall 35b is provided at the bottom of the slit 37b.
Are provided, and a drain hole 42 is provided between the placing portions 41.
It has been. The placement section 41 is naturally formed lower than the upper end of the lower end frame 40 so as to hold the card inserted together with the side end frame 36b. At the upper end of the rear wall 34b, an inclined surface 45 is provided on the slit 37b side,
Therefore, when butted against the rear wall 34a, the notch 38 is formed.
And the inclined surface 45 form a bead retention. Also,
The upper end of the side end frame 36b has an inclined surface 4 on the slit 37b side.
6 are provided. The inclined surface 46 facilitates insertion because the card slides.

[0010] More specifically, the rear walls 34a, 34b and the side end frames 36a, 36b are formed in consideration of displacement during welding. That is, as shown in FIG. 8, in the rear wall 34a and the rear wall 34b, the inner surface 48 of the rear wall 34b is larger than the inner surface 47 of the rear wall 34a (the surface opposite to the slit 37a).
(Surface opposite to the slit 37b) is shifted forward by a distance _{L 1} (slit 37b side). Also, the side end frame 36
a and the inner surface 47 of the side end frame 36a.
The upper end of (slit 37a side of the surface) the inclined surface 46 than is deviated by a distance L ₂ outside (outside of the pallet). Since the dimensions L ₁ and L ₂ are determined in consideration of the displacement at the time of welding, the dimensions L ₁ and L ₂ become zero when the component 24b is shifted inward and welded. Further, the rear wall 34a and the rear wall 34
Although b is welded, the welding allowance is formed smaller than the welding allowance of the other parts, and the side end frames 36a and 36b are not welded but formed so as to abut each other. Therefore,
After the welded portions of the other portions are butt-welded, the rear wall 34 is started.
a and 34b are welded and when the welding is completed, the side end frame 36
a and 36b are formed so as to be merely abutted.

In consideration of the occurrence of beads, the side walls 35a and 35b are preferably formed in the same manner as the rear wall 34a and the rear wall 34b. This does not hinder the insertion of the card, so that the structure may be the same as the other mating surfaces. A notch 49 is provided at the lower end of the rear wall 34b of the component 24b over the length of the slit 37b. By providing the notch 49, deformation at the time of molding due to thick wall can be prevented.

When the card holding portion 31 is formed by butt-welding the components 24a and 24b having the above-described configuration, the bead generated by the butt-welding of the rear wall 34a and the rear wall 34b is stored in the bead stay by the notch 38. This eliminates the need for bead processing and does not hinder card insertion. The rear wall 34b has an inclined surface 45.
Is formed, so that the card can be more easily inserted. On the other hand, the side end frame 36a and the side end frame 36b are hardly welded and are merely abutted with each other. Therefore, no bead is generated and the card can be easily inserted in combination with the inclined surface 46. The inclined portion 3 is provided on the rear wall 34a of the component 24a.
Since the card 9 is provided, a gap is formed on the back side of the card when the card is inserted. By inserting a finger into this gap, the card can be easily held, so that the card can be easily attached and detached. Since the inserted card is held at the peripheral edge of the lower end portion, it does not fall off carelessly and the written contents of the card can be easily read.

In the above embodiment, the card holding portion 31 provided on the component 24 has been described, but the structure of the card holding portion 31 of the other components 26 is also the same. The card holder 31 does not necessarily need to be provided on the component 26,
It is sufficient to provide one or more on one side. The card holder 31 is preferably provided on the side surface where the fork insertion hole 18 is formed in order to facilitate reading of the card during operation.

Next, a structure in which the synthetic resin pallet 10 is used as a pallet with a guard to which a side guard can be detachably attached will be described. When used as a pallet with a guard, it is necessary to erect a support, and a support fitting hole 5 opening on the upper surface of the upper deck board 11 and reaching the lower deck board 12.
2 are provided. In the illustrated embodiment, fourteen columns 16 are provided at equal intervals in the lateral direction X and the longitudinal direction Y, respectively.

[0015] As shown in FIG.
Is the upper component cylinder 5 provided on the inner surface of the upper deck board 11.
3 and lower part cylinder 5 provided on the inner surface of lower deck board 12
4. The upper part cylinder 53 is open to the upper deck board 11, but the tip of the lower part cylinder 54 has a tapered surface 5 whose diameter gradually increases toward the welding surface.
7, a drain hole 58 is formed in the lower deck board 12. Accordingly, since the inner diameter of the upper end of the lower part cylinder 54 is formed larger than the inner diameter of the upper part cylinder 53 by the tapered surface 57, when the upper part cylinder 53 is abutted against the upper part cylinder 53, an annular concave portion 59 having a triangular cross section is formed. This annular recess 59 serves as a bead retention. This prevents the bead from bulging into the cylinder and facilitates the insertion of the strut.

It is preferable that the heights of the upper part cylinder 53 and the lower part cylinder 54 are slightly lower than the heights of the girders and the reinforcing ribs, respectively, to reduce the welding margin. The smaller the welding allowance, the more bead generation can be reduced. In addition, the position and the number of the column fitting holes 52 are not limited to the illustrated embodiment, and can be appropriately determined according to the type and size of the transported object. The cross-sectional shape of the cylindrical body is not limited to a circle, but may be an arbitrary shape such as a polygon such as a triangle and a quadrangle, an ellipse, and a rectangle. The upper part cylinder 5
The peripheral wall of the lower part 3 and the lower part cylinder 54 need not be completely closed, and is particularly limited as long as the column can be stored and erected, such as a lattice structure, a mesh structure, a structure having a plurality of slits, or the like. It is not something to be done. In addition, the above-mentioned column storage hole 19 is effective for storing unnecessary columns, but can be omitted. In a case where the column housing holes 19 are omitted, the both ends girder 15 and the intermediate portion girder 17 may be connected to form an integrated girder, or only the both side surfaces of the column storage holes 19 may be closed.

In the above-described embodiment, the dividing method on the plane is divided by a dividing line parallel to one side surface. It may be divided by a line. Further, the number of the dividing lines is not limited. Furthermore, although the two-sided pallet has been described, it is needless to say that the present invention can be applied to a four-sided pallet.

[0018]

Since the present invention is configured as described above, the following effects can be obtained. That is, in the synthetic resin pallet having the card holding portion according to the first aspect, the card can be easily taken in and out from the upper surface opening,
In addition to facilitating insertion of the card by the inclined portion of the rear wall, a gap is formed on the back side of the card, so that the card can be more easily attached and detached by holding the upper end of the card. Further, the inserted card is securely held by the side end frame and the lower end frame. In addition, since rainwater, dust, and the like are discharged from the drain hole, the pallet can be easily washed, and the card is not contaminated. Further, in the synthetic resin pallet having the card holding portion according to the second aspect, the bead retention is formed by the cutout of the rear wall of the upper part, the rear wall of the lower part, and the inclined surface formed on the upper part of the side end frame. This prevents bead swelling into the slit and facilitates card insertion.

In the pallet made of synthetic resin having a card holding portion according to the third aspect, the occurrence of beads on the rear wall can be reduced and no beads are generated on the side end frames. It does not hinder you. In the synthetic resin pallet having the card holding portion according to the fourth aspect, since the upper part and the lower part are formed in consideration of the welding deviation, the bead swells into the slit of the card holding portion due to the welding deviation. There is no. According to the pallet made of synthetic resin having the card holding portion according to the fifth aspect, the lower part steals meat by the notch, so that deformation during molding can be prevented.
