Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a movable partition with a projection screen, in which the projection screen is incorporated into the movable panel so that the projection screen moves together with the movable panel.

BACKGROUND OF THE INVENTION In hotels, gathering halls, etc., movable partitions that can adjust the size of a room depending on the size of the gathering are often used. In venues created by these movable partitions, visual equipment such as slides, projectors, and videos are frequently used, and images from these projectors are exclusively projected onto projection screens.

By the way, this projection screen includes a movable one,
There are fixed types. The former type mainly stands on the floor via a tripod, etc., and the latter type is fixed to a wall or the like in advance, or a cloth-like item wrapped in a cylinder around the ceiling etc. is used. The main ones are those that are spread out.

Problems to be Solved by the Invention According to the prior art, although the movable projection screen can be installed at any location,
Since they are often placed near the installation location for quick installation, they tend to obstruct traffic and impair the aesthetic appeal. On the other hand, fixed types are less likely to cause obstacles or be aesthetically inferior, but because the installation location is fixed, it is not possible to move the position of the projection screen depending on the size of the gathering, etc. There was a problem.

Therefore, in view of the actual state of the prior art, an object of the present invention is to incorporate a projection screen into a movable panel so that the projection screen can move together with the movable panel, so that the projection screen when not in use does not get in the way of traffic. To provide a movable partition with a projection screen that does not cause the appearance of the room or impair the beauty of the room.

Means for Solving the Problems The present invention has the following configuration: a hanger rail installed on the ceiling, a runner that runs on the hanger rail, a movable panel that is suspended by the runner and movably partitions the room. The gist thereof is to include a projection screen built into the inside of a movable panel, and an opening/closing door disposed on at least one side of the projection screen and shielding the projection screen in an openable and closable manner.

Further, the opening/closing door may be housed inside the movable panel when the door is opened, and may be formed on the same plane as the movable panel when the door is closed.

Furthermore, the opening/closing door can also be driven by a motor.

In this configuration, the movable panel is suspended by a runner that runs on a hanger rail on the ceiling, and the room can be partitioned in a movable manner, so that the projection screen built into the movable panel is If you move the
Along with this, it can be moved arbitrarily, and if the moving panel is stopped and fixed, it can be installed at that location.

At this time, the projection screen is built inside the movable panel and is shielded by an opening/closing door so that it can be opened and closed freely, so when it is not in use, there is no risk of it becoming an obstruction to traffic or coming into contact with other people. do not have. When in use, the projection screen can be easily prepared by simply opening the opening/closing door.

In addition, if the opening/closing door is housed inside the movable panel when the door is open and forms the same plane as the movable panel when the door is closed, the opening/closing door will not waste space in the room when using the projection screen. Furthermore, when the projection screen is not in use, the presence of the projection screen can be completely unnoticed, and there is no risk of impeding its function as a movable partition.

If the opening/closing door is driven by a motor, rapid remote opening/closing operation of the opening/closing door becomes possible.

The projector P can also be moved by using hanger rails HR installed on the ceiling (see the same figure). Like the movable panel 10, the projector P is suspended from the Hungerail HR via the runner 11 hanging the connecting rod 11c, and is mounted in a direction perpendicular to the moving direction of the movable panel 10 or in the same direction as the movable panel 10. All you have to do is make it possible to move to . When not in use, the projector P can be retracted to a predetermined position outdoors or indoors, and the relative distance between the projection screen 12 and the projector P can be changed, improving the beauty of the indoor space and making it easier to move. The degree of freedom in the installation location of the panel 10 can be greatly increased. In addition, the moving panel 10 and the projector P
When the moving direction is the same, the two may be connected in advance with a predetermined spacing between them.

Further, the runner 11 for the projector P may be able to change direction at the intersection of the Hungarian Rail HRSHR (arrow C in the figure) where the runner 11 runs. The projector P can move both parallel and perpendicular to the movable panel 10.

As described in detail, according to the present invention, a projection screen is incorporated inside a movable panel that movably partitions a room, and an opening/closing door is provided to shield the projection screen so as to be openable and closable. The projection screen can be moved along with the moving panel, and when not in use,
Since it is completely hidden inside the movable panel and cannot be seen from the outside, the projection screen can be installed in a location suitable for the size of the gathering, and when not in use, it can be hidden from traffic. It has an excellent effect in that there is no risk of it getting in the way or damaging the aesthetics of the room.
