It is a perspective view showing the side plate of a foldable box in the process of being rotated from the outside to the inside according to one embodiment, Figures 5 and 6 are perspective views showing the process in which the contact protrusion of Figure 4 contacts the protrusion, and Figure 7 is a perspective view of the present invention It is a perspective view showing the side plate of the folding box according to one embodiment while rotating from the inside to the outside, and FIGS. 8 and 9 are perspective views showing the process in which the contact protrusion of FIG. 7 contacts the protrusion with each other, and FIGS. 10 to 10 12 shows the movement of the movable member within the movable groove of the folding box according to an embodiment of the present invention.

First, referring to FIGS. 1 to 3, the folding box according to an embodiment of the present invention includes a rectangular bottom plate 100 and four side plates each rotated so as to be able to stand upright at the four corners of the bottom plate 100. A movable member (300) provided with (210, 220, 230, 240) and formed to be horizontally movable on any pair of opposing side plates (210, 220) among the four side plates (210, 220, 230, 240). ) may include.

The movable member 300 may include a body portion 310 having a grip portion 316 and a rod 311 extending from the body portion 310.

The body portion 310 has an elastic piece 315 protruding outward, and a rod 311 that extends along the longitudinal direction at one end along the longitudinal direction of the body portion 300 and is stepped to reduce the width. ) may include. Here, the elastic piece 315 moves along the movable groove 210a by elastically deforming the inner walls on both sides of the movable groove 210a formed inside the side plate 210 where the body portion 310 is located. Ensure that elastic restoring force is provided.

The rod 311 is formed to be reduced by a predetermined thickness in the body portion 310, and is deformed to assist a small amount of elastic deformation of the elastic deformation portion 312, which will be described later, so that the contact protrusion 313 smoothly passes over the protrusion 231. Let’s do it.

Elastic deformation parts 312 that protrude on both sides may be formed at ends of the rod 311 along the longitudinal direction.

Each elastic deformation portion 312 may protrude vertically from the outer surface of the rod 311.

The contact protrusion 313 may be formed integrally with the elastic deformation portion 312. It is preferable that the elastic deformation portion 312 be formed thinner than the thickness of the rod 311 so that relatively more elastic deformation occurs.

The end of each contact protrusion 313 may include a movable inclined surface 314 inclined in opposite directions.

A protrusion 231 is formed from an edge of the side plate 230 corresponding to each movable inclined surface 314 and may be in sliding contact with the movable inclined surface 314. At this time, the support inclined surface 231a in contact with the movable inclined surface 314 of the protrusion 231 may be formed to have an inclination that corresponds to and is in close contact with the adjacent inclined surface 314.

The first direction D1 and the second direction D2, which will be described later, define the direction in which one of the side plates is rotated inward as the first direction D1, and the direction in which one of the side plates is rotated outward is defined as the first direction D1. Defined as the second direction (D2).

As shown in Figures 2 and 3, a movable inclined surface 314 is formed on one side of one of the pair of contact protrusions 313, and is movable on the other side of the other contact protrusion 313. An inclined surface 314 may be formed.

In other words, this may mean that each movable inclined surface 314 is formed to face opposite directions in the first direction D1 and the second direction D2.

It may include a support inclined surface 231a that protrudes from an edge of the side plate 230 corresponding to the movable inclined surface 314 and is formed on each of the movable inclined surfaces 314.

The support inclined surface 231a may be formed to have an inclination that corresponds to and is in close contact with the adjacent movable inclined surface 314. The support slope 231a has an inclination that corresponds to and comes into close contact with the movable slope 314, thereby allowing the movable slope 314 to slide over the support slope 231a in the process of progressing. I do it.

Hereinafter, the operation of a folding box according to an embodiment of the present invention will be described with reference to the attached drawings.

Figure 4 is a perspective view showing the side plate of a foldable box in the process of rotating from the outside to the inside according to an embodiment of the present invention, and Figures 5 and 6 are perspective views showing the process in which the movable member of Figure 4 contacts the protrusion with each other. .

Referring to FIGS. 4 to 6, in the process of rotating one of the side plates 210 on which the movable member 300 is installed from the second direction D2 to the first direction D1, contact is made as shown in FIG. 6. When the movable inclined surface 314 of any one of the contact protrusions 313 among the protrusions 313 is in surface contact with the supporting inclined surface 231a and continues to proceed along the rotation direction, the movable inclined surface 314 moves against the supporting inclined surface 231a. It passes along.

At this time, the movable inclined surface 314 is pushed by the supporting inclined surface 231a and at the same time, elastic deformation of the elastic deformation portion 312 occurs in a direction away from the supporting inclined surface 231a.

In this process, friction occurs between the movable inclined surface 314 and the supporting inclined surface 231a, and the movable inclined surface 314 passes over the supporting inclined surface 231a.

Thereafter, as shown in FIGS. 10 to 12, when the movable inclined surface 314 rotates along the first direction D1 and passes over the supporting inclined surface 231a, the elastically deformed contact protrusion 313 is elastically deformed into an elastically deformed portion 312. ) can be returned to its original position by the elastic restoring force.

In addition, the movement of the side opposite to one of the movable inclined surfaces 314 along the first direction D1 in the second direction D2 is restricted by the opposite side 231b of the supporting inclined surface 231a.

However, the other movable inclined surface 314 is formed to face the second direction D2, so that when an external force is applied toward the second direction D2, it can go over the support inclined surface 231a. That is, the contact protrusion 313 is capable of moving not only along the second direction D2 but also along the first direction D1.

In addition, the movable members 300 are arranged symmetrically to each other on the first side plate 210, but when each gripping part 316 is arranged close to each other, the pair of gripping parts 316 are held with the user's thumb and index finger. When retracted, the contact protrusion 313 of the movable member 300 of the first side plate 210 is released from its restraint with the protrusion 231, allowing the first side plate 210 to rotate freely. At this time, the rod 311 side of the contact protrusion 313 may have a predetermined thickness, and a collision surface 313a may be formed close to the elastic deformation portion 312. This is to prevent a case in which the elastic deformation part 312 is deformed toward the movable inclined surface 314, making it impossible to release the restraint between the contact protrusion 313 and the support inclined surface 231a, and the elastic deformable part 312 is movable. This is to minimize the extent of deformation toward the inclined surface 314 due to collision with the collision surface 313a.

Figure 7 is a perspective view showing the side plate of a foldable box in the process of rotating from the inside to the outside according to an embodiment of the present invention, and Figures 8 and 9 are perspective views showing the process in which the contact protrusion of Figure 7 contacts the protrusion with each other. .

7 to 9, in the process of rotating one of the side plates 210 on which the movable member 300 is installed from the first direction D1 to the second direction D2, as shown in FIG. When the movable inclined surface 314 of one contact protrusion 313 is in surface contact with the supporting inclined surface 231a and continues to proceed along the rotation direction, the movable inclined surface 314 is pushed by the supporting inclined surface 231a and the elastic deformation portion 312 is deformed, and the movable inclined surface 314 passes through the supporting inclined surface 231a.

In addition, an elastic restoring force is provided to the contact protrusion 313 by the elastic deformation portion 312 that is deformed in the process of the movable inclined surface 314 being pushed by the supporting inclined surface 231a.

That is, referring again to FIGS. 10 to 12, in the process of rotating the side plate 210 along the first direction D1, the contact protrusion 313 is formed on the support inclined surface 231a due to deformation of the elastic deformation portion 312. When passing through, the contact protrusion 313 may be returned to its initial position by the elastic restoring force of the elastic deformation portion 312.

Thereafter, the side opposite to one of the movable inclined surfaces 314 along the second direction D2 is restricted from moving along the first direction D1 by the opposite side 231b of the supporting inclined surface 231a. However, the other movable inclined surface 314 is formed to face the first direction D1, so that when an external force is applied in the first direction D1, it can pass over the support inclined surface 231a. That is, the contact protrusion 313 can move not only along the first direction D1 but also along the second direction D2.

Therefore, the foldable box according to an embodiment of the present invention not only has a foldable structure with a simplified configuration, but can also be freely folded inside and outside.

As described above, the folding box according to an embodiment of the present invention has been described with reference to the drawings, but the present invention is not limited by the embodiments and drawings described above, and the technology to which the present invention pertains within the scope of the patent claims. Various implementations are possible by those with ordinary knowledge in the field.
