Abstract

A collapsible container having a horizontal hinge module, according to the present invention, comprises: collapsible side-wall panels (130) between an upper panel (120) and a lower panel (110); and a horizontal hinge module (140) which collapsibly connects the lower/upper panels (110, 120) and the side-wall panels (130) and, at the same time, is disposed in an unexposed state on the insides of the side-wall panels (130). The horizontal hinge module (140) comprises: a first hinge part (150) disposed on the upper/lower end parts of the side-wall panels (130) along the longitudinal direction of the container; a second hinge part (160) disposed on the upper/lower end parts of the side-wall panels (130) along the longitudinal direction so as to be spaced apart from the first hinge part (150); and a torsion part (170) which connects the first hinge part (150) and the second hinge part (160) with each other. The torsion part (170) comprises a pair of torsion bars, wherein the torsion bars in the pair of torsion bars consecutively undergo torsional rotation respectively at a preset angle, namely 45 degrees, in the collapsing process of the side-wall panels (130), thereby storing a constant amount of torsional elastic energy, and thus enabling the adjustment of the load capacity of the pair of torsion bars.

Description

Folding container with horizontal hinge module

The present invention relates to a foldable container technology to which the hinge system of the horizontal arrangement structure is applied, and specifically, a plurality of torsion bar structures mounted to be used for folding the side wall panels of the foldable container to exert sufficient elastic force to easily fold the side walls of the container. Is for a folding container having a horizontal hinge module.

In general, a container is a large box formed of steel plates and is mainly used for cargo transportation. Such a container is widely used because it is easy to store and transport the cargo, and also has the advantage of protecting the cargo contained therein. Such containers are individually transported by large freight vehicles used exclusively or in large quantities by dedicated trains or dedicated ships.

It is well known that such a container is made of a size having a certain size and is easy to transport, and has a merit of protecting a cargo contained therein. However, because these containers are made of steel, they occupy the same space with cargo inside or empty. Therefore, even when storing or transporting an empty container, there is a problem in that the same volume and cost as in transporting cargo therein occur.

In order to solve this problem, there have been attempts to solve this problem by allowing the container to be folded in an empty container state.

Referring to Korean Patent No. 10-1064803 as a conventional technique for reducing the volume of an empty container, a method of folding a container side wall using a belt is disclosed. The hinge is connected, and in order to fold the side wall, the belt is attached to both side walls, and the center of the side wall is moved to the inside of the container by pulling the belt to fold the container. However, this method has to be attached to the belt for folding the container separately, there is a problem that the spring provided in the middle of the side wall only serves as a simple hinge and does not use the elastic force stored in the spring in the folding process.

Meanwhile, in the related art, a method of storing a torsional elastic energy by mounting a single torsion bar on a folding portion connecting the upper and lower panels and the side wall panel of the container while folding the side wall of the container is used. When the bit folds the side wall panel through the process, excessive twisting is applied on the torsion bar, which causes a problem in that the side wall panel can be folded and restored.

In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

In addition, in describing the component of this invention, terms, such as 1st, 2nd, A, B, (a), (b), can be used. These terms are only for distinguishing the components from other components, and the nature, order or order of the components are not limited by the terms. If a component is described as being "connected", "coupled" or "connected" to another component, that component may be directly connected to or connected to that other component, but between components It will be understood that may be "connected", "coupled" or "connected".

In the following description, expressions such as “folding” to “folding” or “folding” shall mean an operation of folding a side wall panel of a container.

The folding container of the present invention (hereinafter referred to as "container") is the lower panel 110, the upper panel 120, the lower panel 110 and the upper panel 120 which are spaced apart on the upper portion of the lower panel 110. The side wall panel 130 is installed on both sides between, the door panel (not shown) and the upper and

lower panels

110, 120 which are mounted in a direction perpendicular to the front and rear of the container 100 and can be opened for internal cargo loading and unloading. And a horizontal hinge module 140 that is foldably connected between the side wall panels 130 and is disposed in an unexposed state on the inner side of the side wall panel 130.

In addition, the upper sidewall panel 131 and the lower sidewall panel 133 are interconnected by the main hinge structure 135. Meanwhile, the main hinge structure 135 may be installed in a state in which a plurality of main hinge structures 135 are formed at predetermined intervals in a longitudinal direction connecting the front and rear sides of the container 100 along the side wall panel 130 of the container 100.

In the process of folding the side wall panel of the container, the upper side wall panel 131 and the lower side wall panel 133 rotate 90 degrees, respectively. In this process, the hinge is connected to the upper side wall panel 131 and the lower side wall panel 133. It is fixed and rotates together. Conventionally, when using a cam-spring hinge only, the elastic energy stored is not enough to prevent the spreading operation.

If only one torsion bar is used to store the elastic energy required for the unfolding process, there is a problem that the elastic energy stored in the folding process may be excessively large. In the present invention, a pair of torsion bars is used, but the pair of torsion bars is used. By properly adjusting the torsion bar's torsion angle, the load capacity applied to the torsion bar can be appropriately reduced, so the elastic torsion energy is stored and released on the pair of torsion bars during the folding operation of the side wall panel. I can do it.

Can be. That is, each of the torsion portions 170 disposed along the sidewall panel 130 may have a form in which the first hinge portion 150 and the second hinge portion 160 having different shapes on each side thereof are coupled to each other. have. In other words, for example, the first hinge part 150, the torsion part 170, the second hinge part 160, the torsion part 170, and the first hinge part 150 along the upper and lower ends of the side wall panel 130.

That is, as shown in FIGS. 7 to 8, the first hinge part when the side wall panel 130 that performs the 45-degree rotation operation primarily through FIGS. 5 to 6 performs the secondary folding process. The first rotating body 156 of 150 and the second rotating body 166 of the second hinge 160 make a second 45 degree rotational motion. In the above process, one end of the second torsion bar 176 is fixed to the first rotating body 156 so as not to rotate, and the other end of the second torsion bar 176 is rotated according to the rotation of the second rotating body 166. The torsional motion is performed by rotating 45 degrees about the second rotary shaft 186. Here, the other end of the second torsion bar 176 freely rotates on the second connecting body 164. Through this, the torsional elastic energy is stored on the second torsion bar 176.
