Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen suitably used in an office or the like.

[0002]

2. Description of the Related Art Conventionally, a screen has been used as a means for easily partitioning an office space as needed. Of these, recent screens have a large number of screen elements arranged in the width direction, and the side edges of adjacent screen elements are rotatably connected to each other via a connecting member so that the entire planar shape can be deformed. There are not a few things.
The reason for this is that offices are often equipped with furniture that can be freely rearranged in order to improve the functionality of the office in recent years, and the screen is resilient to such changes in office form. This is because it is necessary to provide flexibility to be able to cope with the situation.

[0003]

However, most existing screens have upper and lower ends of adjacent screen elements connected to each other by a pair of upper and lower link members so as to be relatively rotatable. Specifically, one side edge of one screen element is connected to one side hole of the link member having a pair of shaft holes at both ends, and the other side edge of the screen element adjacent to the other side hole is connected to the other side edge. When each screen element is opened substantially in a straight line, the link member is disposed along the surface direction of the screen element. It is. However, in this case, a gap is generated between adjacent screen elements by an amount substantially equal to the separation distance between both shaft holes, particularly when each screen element is opened substantially in a straight line during rotation. In addition, not only the appearance of the entire screen deteriorates, but also the scenery on the other side of the screen leaks from the gap, and light leaks from the gap. Further, since the screen element is rotatably mounted on both ends of the link member so that the screen element can be freely rotated, the rotation direction of the screen element is reversed by the upper and lower link members. And the screen element could be damaged by twisting at the upper and lower ends.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention makes it possible to rotate adjacent screen elements by a connecting member projecting in a direction intersecting the surface of the screen elements. The structure to connect is adopted.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS That is, the screen of the present invention has a large number of screen elements arranged in the width direction, and the side edges of adjacent screen elements are rotatably connected to each other via a connecting portion so as to be entirely deformed.

At that time, in the present invention, since the adjacent screen elements are rotatably connected to each other by a connecting portion projecting in a direction intersecting with the surface of the screen element, each screen element is opened substantially in a straight line. Of course, the side edges of the adjacent screen elements always overlap in the thickness direction even during the rotation, and it is possible to effectively prevent a gap from being generated between the screen elements. Therefore, the appearance can be improved, and it is possible to effectively prevent the scenery on the other side from leaking out from the gap or light from leaking.

In a preferred embodiment of the screen element, the screen element includes a sheet-like screen element body, left and right side frame members supporting left and right side edges of the screen element body, and the left and right side members. One provided with upper and lower frame members connecting the upper and lower ends of the frame member can be cited. In the case where the screen element body is a thin sheet, the screen element body is desirably supported by the left and right side frame members in a curved state in order to increase rigidity and improve strength.

In order to prevent the screen element main body from wrinkling when the screen element main body expands and contracts due to an external factor such as a temperature change, the screen element main body is not restrained with respect to the upper and lower frame members. Is good. As an embodiment of the connecting portion, there can be cited a connecting member in which the connecting portion is provided separately from the screen element and is fixed to one side edge of one of the screen elements.

In order to reduce the number of parts, the connecting portion may be provided integrally with the upper and lower frame members. In order to prevent the user from feeling oppressed even when all the screen elements are opened, it is desirable that the screen element main body has translucency.
