Effects of the Invention and Effects of the Invention

In the opening and closing device for a wall plate according to the present invention, the wall is constituted by moving each of the plurality of support members fixed to the plate in the substantially parallel direction by the parallel direction moving means. The plate moves in a substantially horizontal direction. That is, the plate material supported by the support member can be opened and closed without providing a frame on the plate material.

Further, since each of the plurality of support members fixed to the plate is moved in the substantially parallel direction by the parallel moving means, the center of gravity of the plate does not move up, down, almost or not at all. When the center of gravity of the plate material moves in the vertical direction, a large operation force is required to move the heavy plate material in the vertical direction. However, in the present invention, as described above, the center of gravity of the plate material hardly or vertically moves at all. Therefore, the operation force for moving the plate material is small. This also makes it possible to make the moving means compact.

Further, when the center of gravity of the plate material moves in the vertical direction, a large load is applied to the support member supporting the heavy plate material, and a large load is applied to the plate material to which the support member is fixed in the vertical direction. Since a plate material may be broken when a large load is applied, it is necessary to minimize the load applied to the plate material. In the present invention, as described above, since the center of gravity of the plate material hardly moves up and down or hardly moves at all, the plate material of the portion to which the support member is fixed is hardly or at all subjected to a load for moving in the vertical direction. The load applied to the plate material due to the movement of the member can be minimized.

Since the plate member is supported via the support member, when a stress in the rotational direction is applied to the support member by the weight of the plate member, the rotational stress is also applied to the plate member, and the plate member is supported. It may be damaged. However, the moving means supports the support member on the vertical line of the through-hole, so that a load in the rotating direction is not applied to the support member receiving the weight of the plate material, thereby eliminating a problem that the plate material is damaged by rotational stress. .

With this arrangement, when the male screw 8a is rotationally driven, the female screw 8b moves and the other end 5b of the arm 5 slides. Here, when the other end 5b of the arm 5 slides and the distance between the other end 5b of the arm 5 and the other end 7b of the lever 7 approaches, the one end 5a (the support member 2) of the arm 5 moves outward in parallel. Conversely, when the distance between the other end 5b of the arm 5 and the other end 7b of the lever 7 increases, the one end 5a (support member 2) of the arm 5 moves inward.

The shape of the arm unit of each slide means 8 (substantially inserted type) is vertically symmetrical, and one end of each arm 5 (that is, the glass 1 supported by each support member 2) is If the support column 4 is vertical, it is provided to move in the horizontal direction.

That is, the glass 1 supported by the support member 2 can be opened and closed without providing a frame on the glass 1.

Since each of the plurality of support members 2 fixed to the glass 1 is moved in the parallel direction by the parallel direction moving means 3, the glass 1 is opened and closed when the glass 1 is opened and closed.
The center of gravity does not move up and down at all. Therefore, the operation force for moving the glass 1 is small, and the moving means 3 (the arm unit, the sliding means 8 and the electric motor 9 for operating the sliding means 8) can be made compact.

Further, since the center of gravity of the glass 1 does not move up and down at all when the glass 1 is opened and closed, no load is applied to the portion of the glass 1 to which the support member 2 is fixed for vertical movement. The load applied to the glass 1 due to the movement can be minimized.

Further, a supporting means may be constituted by a hydraulic cylinder or the like, and the supporting member 2 may be moved in a substantially parallel direction.

In the above embodiment, the moving means 3 is operated by the operation of the electric motor 9, but the moving means 3 is driven by a manual operation so that the plate (glass 1) is manually opened and closed. Alternatively, the plate member (glass 1) may be opened and closed by driving the moving unit 3 by a fluid actuator such as a hydraulic pressure.

In the above embodiment, the glass 1 is shown as an example of the plate material. However, a transparent, translucent, opaque resin (for example, acrylic resin, polycarbonate resin, etc.), a metal plate, a concrete plate, a wood plate For example, another plate material may be used. That is, the present invention may be used as a device for opening and closing a plate material other than glass.
