The present embodiment is suitable for a multi-purpose assembled toy box made of synthetic resin, which is also used for multiple purposes, such as a pulling vehicle with casters.

First, the overall outline will be described. The toy box 1 is roughly composed of four PP side plates 2, 2, ..., One PP bottom plate 3 and four nylon casters-4, 4 and is located above (upper side in FIG. 2). (Hereinafter, the upper, lower, left and right sides will be described for the sake of convenience with reference to FIG. 2).

The four side plates 2 have the same shape and size. For example, width 315mm, height 285mm,
The resin thickness of about 2 mm is made into a shallow dish, and the shallow dish depth t =
It has a size of 23 mm. Then, the side plates 2 are assembled by superposing and fitting.

Next, each part will be described in detail. Side plate 2
2, the upper edge is the opening side and the bottom plate 3 is attached to the lower edge. Further, hollow convex portions 6 and tongues 7 with locking claws are alternately projected on the right side edge, and a notch into which the hollow convex portion 6 of another side plate 2 is fitted is formed on the left side edge. Spaces 8 and locking projections 9 for locking the tongues 7 with locking claws are alternately formed and projected.

The hollow convex portion 6 is provided for each core of the toy box 1.
In order to give the roundness to the roundness, except for the one at the top, it is formed in the shape of a four-hemisphere upper and lower ring whose radius is the shallow dish depth t,
The hollow convex portion 6a at the upper end is formed in a four hemisphere lower circular cut shape.

As shown in FIG. 3, the tongue 7 with the locking claw is
The tongue piece 7a is formed of a rectangular plate, and a locking claw 7b is formed on one side of the tip of the tongue piece 7a, and a projection 7c is formed on one side of the base end (see FIG. 5). A rib 7d is provided on the other side surface of the tongue piece 7a to increase the resin elastic force. Tongue piece guide pieces 10, 10 are provided on the side of the tongue piece 7 with the locking claws with a slight gap therebetween. This tongue piece guide piece 10 is formed of a plate.

The locking projection 9 has the same outer shape and the same size as the hollow projection 6. A guide piece 11 for the locking projection is provided inside the locking projection 9, and the guide piece 11 for the locking projection is the guide piece 10 for the tongue piece.
And are arranged in an orthogonal state. Further, a locking claw hole 12 is provided in the base 2a of the side plate 2 on which the locking projection 9 is projected. Of course, if the shape of the locking projection 9 is not a four-hemisphere upper and lower ring-cut shape but a simple box shape, the locking projection guide piece 11 is unnecessary.

Then, as shown in FIG.
The distance L1 between b and the projection 7c is the hole 1 for the locking claw of the locking projection 9.
Tongue piece guide piece 1 is made equal to the distance L1 up to the opening end of 2.
The width L2 of 0 is made equal to the distance L2 to the position where the locking projection guide piece 11 is arranged.

Therefore, as shown in FIG.
Is inserted into the locking projection 9 as indicated by the arrow a, the tongue pieces 7 with locking claws are slightly deformed by the resin while the tongue guide pieces 10, 10 are guided by the locking projection guide piece 11. Then, the locking claw 7b is locked in the locking claw hole 12. As a result, the tongue piece 7 with the locking claw and the locking convex portion 9 are so-called fit-and-kill in the direction of the arrow b, and cannot be easily disassembled.

Further, at the lower edge of the side plate 2, there is provided a bottom plate insertion hole 13 into which the insertion piece 3a of the bottom plate 3 can be inserted. A tongue-shaped foot 14 is provided on the outside of the bottom plate insertion hole 13. The tongue-shaped legs 14 are effective when the toy boxes 1 are stacked or when the casters 4 are not attached.

Next, the bottom plate 3 will be described. The bottom plate 3 is formed in a square shape, and a grid-like rib (not shown) is reinforced on the back surface so that it will not be deformed when an infant rides on it. The insert piece 3a is formed on each side of the bottom plate 3 as described above.

Next, the caster-4 will be described. Figure 6
As shown in Fig. 4, the caster-4 has an eccentric position.
A shaft 15 is provided, is inserted into a bearing portion 16 protruding from the base portion 2a of the side plate 2, and is prevented from rotating by a locking device (not shown). Since the bearing portion 16 is covered by the hollow convex portion 9b at the lower end of the other side plate 2, the caster shaft 16 is also inserted in the hollow convex portion 9b, and therefore, the caster shaft 15 is also adjacent. The side plates 2 and 2 are locked to each other.

Next, the operation of this embodiment will be described. For example, the four side plates 2 are individually colored in red, yellow, blue, and green, and injection-molded. Therefore, only one type of injection mold is required. The molded side plate 2 and bottom plate 3 can be carried as they are from a store and assembled at home. The assembly is performed by first inserting the insertion piece 3 of the bottom plate 3.
While inserting a, 3b ... Into the bottom plate insertion holes 13 of the four side plates 2, the hollow projection 6 is fitted with the notch space 8 and the tongue piece 7 with the locking claw is fitted with the locking projection 9. Then, they are superposed and fitted to each other by concavo-convex. At this time, in particular, the tongue 7 with the locking claw is slightly resin-deformed to lock the locking claw 7b in the locking hole 12.
Then, the caster 4 is pushed into the bearing portion 16 to complete the toy box 1.

Therefore, when a load is applied to the completed toy box 1 from above, the hollow convex portion 6 and the locking convex portion 9 which are superposed and fitted into each other are opposed to each other, and the load is applied from the lateral direction. And the bottom plate 3 and the tongue piece 7 with the locking claw, the base portion 2a of the side plate 2, the horizontal guide pieces 10 and 10 and the vertical guide piece 11 mainly oppose each other, so that the locking claw piece 7 utilizing resin elasticity is used. The toy box 1 is less deformed as compared with the case where only the engaging claw 7a of FIG.

Next, the reinforcing frame 17 will be described. Figure 7
A perspective view of the reinforcing frame 17 is shown in (A), and a sectional view thereof is shown in (B). The reinforcing frame 17 is formed of a PP material having an L-shaped cross section into a square shape, and It is attached to the upper edge of the opening. At the time of assembly, the mounting method is such that it is sandwiched between the inner ribs and brackets of the side plate 2 (neither shown) and the inner surface of the hollow convex portion 6a at the upper end. The portion where the hollow convex portion 6a is located has a U-shaped cross section and is provided with a notch 18. Therefore, the reinforcing frame 17 can prevent the toy box 1 from being deformed, like the bottom plate 3.

Although the toy box of this embodiment has been described as a box body having an upper opening, the present invention is not limited to this and may be a toy box having an appropriate lid. Further, although the toy box of this embodiment has four side plates of the same size, the present invention is not limited to this, and two side plates of the same size and other two side plates of the same size may be used. Therefore, the bottom plate may be rectangular. Further, the tongue piece 7 with the locking claw, the locking projection guide piece 11 and the locking hole 12 of the locking projection 9 may be partially omitted.

[0024]

According to the present invention, although the four side plates are assembled with the tongue pieces with the locking claws utilizing the resin elasticity, the overlapping claw fitting and the locking claws are used for the locking claws. The toy box is firmly assembled by the fitting and killing that is locked in the hole, and will not be deformed even if external forces from multiple directions are applied. As a result, it can be used not only for storing toys but also for vehicles and the like. Further, since the side plates are formed in a shallow dish and the quadrangular reinforcing frame is mounted, a thick wooden-like feeling can be obtained, and more robust assembly can be achieved.
