DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding unit structure mainly used for displays such as display shelves and also for furniture such as desks and tables.

[0002]

2. Description of the Related Art Generally, in stores and product display venues,
Unique shapes, for example, using display shelves of geometric shapes and combinations, as a whole, a display that constitutes a highly artistic atmosphere is implemented, but such display shelves are
It is bulky as a whole, is cumbersome to carry, and it is inconvenient to carry it in and out of display places.

[0003]

Therefore, at least a pair of foldable legs are provided between the upper panel and the lower panel, and the upper and lower ends of the legs are hinged to the upper and lower panels, respectively. A folded unit structure was proposed for the display. With this structure,
It is convenient to carry in and out because the whole can be compacted. However, when assembling, it is troublesome to adjust the horizontality of the upper and lower panels, and if the adjustment is insufficient, the balance of the entire display shelf array is impaired, and the display effect at an angle cannot be exhibited.

The present invention has been made on the basis of the above circumstances. By folding, the entire structure can be made compact, and at the time of assembly, the flatness of the panel can be automatically adjusted only by standing the leg plate. It is an object of the present invention to provide a folding unit structure for a display or the like, which is devised so as to ensure the above.

[0005]

For this reason, in the folding unit structure of the present invention, as is apparent from the embodiment shown in FIG. 1 to FIG. At least one pair of folding leg plates 3 in which the plate members 3A and 3B are hinged to each other,
Connect the upper and lower ends of the leg plate 3 to the upper and lower panels 1 and 2, respectively.
Hinged. Then, each of the pair of leg plates 3
Are hinged to the upper and lower panels 1 and 2 or between the upper and lower plate members 3A and 3B in a direction in which the direction of the hinge axis is crossed. In addition,
A case where another folding leg plate is provided in addition to the pair of leg plates for coupling between the lower panels 1 and 2 (when the upper and lower panels are joined by three or more folding leg plates). )
In this case, the directions of the hinge axis of one of the pair of leg plates and the hinge axis of the other leg plate may be parallel.
In this case, the leg plate 3 has a configuration in which at least a pair of plate members 3A and 3B that are folded up and down are hinged to each other. Each hinge connection axis of the pair of plate members 3A, 3B is in the same direction as the surfaces of the upper and lower panels 1, 2 and always has the same height regardless of the opening / closing angle of the pair of plate members 3A, 3B. The mounting angles of the leg plate 3 with respect to the upper and lower panels 1 and 2 are set such that the angles of the extension lines in the axial direction intersect, that is, intersect.

[0006] Further, it is desirable to use a hinge fitting which is automatically or manually fixed at the desired opening / closing angle in an analog or digital manner at the hinge connection portion. In addition, the plate members 3A and 3B can be erected by a fixing means that is held at a required angle. For that,
The fixing means is inserted between one of the upper and lower panels 1 and 2 and a leg plate hinged thereto, or between both plate members 3A and 3B sandwiching the hinge portion of each leg plate 3. Interposed member or upper / lower panel 1,
It is good to be a pillar member interposed between the two.

In such a configuration, the pair of leg plates 3 intersect the upper and lower panels 1 and 2 or between the upper and lower plate members 3A and 3B in the direction of the hinge axis in the same plane. Since the hinges are hinged in the direction in which they are made, the horizontal structure of the panels is automatically ensured when the leg 3 is erected by the connection structure between the upper and lower panels 1 and 2 and each leg 3. For this reason, when assembling the folding unit structure as a display on site, it is sufficient to simply raise the leg plate 3 to a required height and fix it by the above-described fixing means.

The folding unit structure can be used not only for displays such as display shelves in stores and display halls, but also for general furniture such as desks and tables. In this case,
Not only the upper surfaces of the lower panels 1 and 2 but also the inclined surface of the leg plate 3 can be used as a surface for placing or displaying articles or the like.

[0009]

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 illustrates the most basic structure of the present invention. Here, at least one pair of foldable leg plates 3 is disposed between the rectangular upper panel 1 and the lower panel 2 having the same shape.
The upper and lower ends 3 are hinged to the upper and lower panels 1 and 2 via hinge members 4, respectively. In particular, each leg plate 3, relative to the upper and lower panels 1, 2,
The hinges are hinged in a direction in which the directions of the hinge axes intersect in the same plane, in this embodiment, orthogonal directions.

In this case, as a preferred embodiment, the leg plate 3 has a structure in which at least a pair of plate members 3A and 3B which are folded up and down are hinged to each other via a hinge member 5. The portion can be erected by a hinge fitting or fixing means (described later) such that the plate members 3A and 3B are held at a required angle. Each leg plate 3 is set in a direction in which the hinge axes of the hinge members 5 cross each other. A hinge shaft of a hinge member 4 for hinge-joining the upper and lower sides of the leg plate 3 and the leg plate 3
The hinge axes of the hinge member 5 for hinge-connecting the pair of plate members 3A and 3B are parallel to each other.

In such a configuration, the pair of leg plates 3 intersect with the upper and lower panels 1 and 2 or between the upper and lower plate members 3A and 3B in the direction of the hinge axis in the same plane. Because the hinges are hinged in the direction in which the legs 3 are connected, the upper and lower panels 1 and 2 and each leg 3 are connected automatically (with a mechanical structural necessity). The levelness of the panel is ensured. For this reason,
When assembling this folding unit structure on site as a display, it is sufficient to simply raise the leg plate 3 to a required height and fix it with the above-mentioned hinge fitting or fixing means.

As another embodiment, FIG. 2 shows an example in which the crossing direction of the hinge axis is set to 45 degrees. The embodiment shown in FIG. 3 is an example in which leg plates 3 are attached to the four sides of the upper and lower panels 1 and 2, respectively, in which the upper and lower panels 1 and 2 are connected by two pairs of leg plates. It is. Further, in the embodiment shown in FIG. 4, unlike the embodiment shown in FIG. 1, a pair of small leg plates 3 are mounted on the upper and lower panels 1 and 2 so as to approach one side of the panel.

Further, the embodiment shown in FIGS.
This is an example in which one of the lower panels 1 and 2 is formed in a frame shape such as a U shape or an L shape. In this embodiment, the lower panel 2
A notch 2A is formed at the center of the front edge of the upper panel 1, and a drawer 1A having a shape and thickness that fits into the notch 2A from above is formed at the front of the lower surface of the upper panel 1. At the rear of the lower surface of the upper panel 1, a drawer 1B having a shape and a thickness to be fitted between the folded upper and lower panels 1 and 2 is formed.
The thickness of the drawer 1A is equal to the thickness of the lower panel 2 plus the thickness of the upper and lower plate members 3A and 3B, and the thickness of the drawer 1B is the thickness of the upper and lower plate members 3A and 3B. be equivalent to. In the desk or display stand according to this embodiment, the upper and lower panels 1 and 2 and the upper and lower plate members 3 in the folded state shown in FIG.
A, 3B and drawers 1A, 1B are folded in a flat state in which they are in close contact with each other. Further, as in this embodiment, the lower panel 2 is formed into a U-shaped or L-shaped frame shape, and
Is rectangular so that the lower panel 2 does not hinder cleaning or the like, and the upper panel 1 can be used widely.

FIG. 8 exemplifies a shelf structure in which display units having the above-mentioned folding unit structure are appropriately stacked and the required geometrical form is adjusted. Thus, a display effect can be exhibited.

The fixing means may be provided, for example, as shown in FIG. 9 between one of the upper and lower panels 1 and 2 and a leg plate hinged thereto, or as shown in FIG. A pair of plate members 3A sandwiching the hinge portion of each leg plate 3,
It is good to be the interposition member 6 or 7 inserted between 3B. Further, as shown in FIG. 11, the fixing means may be a column member 8 interposed between the upper and lower panels 1 and 2.
