[Object of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a setback system for advancing and retreating screens, whiteboards, etc. used in conference rooms, training rooms, etc. The present invention relates to an opening / closing mechanism for smoothly performing the opening / closing operation of the device and an opening / closing method using the mechanism.

[0002]

BACKGROUND OF THE INVENTION Recently, a screen, whiteboard, etc., installed in a conference room, a training room, etc., has become popular as a setback system that stands by behind a wall when not in use and advances to the wall only when in use. ing. An example of a specific structure is a two-piece structure in which a part of the wall is removed to accommodate the screen, whiteboard, etc., and this opening is usually decorated (when not in use) with the same quality as the wall. The veneer is located. Then, for example, when a whiteboard is used in a meeting or the like, when a switch corresponding to the whiteboard is pressed, the decorative plate is automatically retracted and further opened left and right to open the opening. Next, after the two members constituting the whiteboard move from the left and right to meet at the rear of the opening, they advance to the front and are positioned at the opening to be in use. In other words, the whiteboard and the decorative plate have a two-piece structure in which the two members are connected to each other so that the area of the whiteboard and the decorative plate is approximately the same as the opening.

Conventionally, when a whiteboard or the like is moved to the rear of the opening from the left and right, a mechanism using a wire, a gear or the like is used. If such a mechanism is adopted, the gear and the wire are first used. The noise was very noisy, and it was very annoying especially during meetings. Furthermore, the sound when the two whiteboards were combined was not only noisy, but after the collision, they were separated by too much force, sometimes creating gaps. Considering that such a whiteboard is often used for meetings, trainings, lectures, etc., such a situation impairs the solemn atmosphere of the entire venue, and there has been a demand for improvement.

[0004]

[Technical Items Attempted to Develop] The present invention has been made from such a background, and when a screen, a whiteboard, or the like is advanced, a white two-component white structure is surely and smoothly formed without producing an offensive sound. This is an attempt to develop an opening / closing mechanism and a opening / closing method using the mechanism in a new setback system such as a screen that allows close contact of boards and the like.

[0005]

Configuration of the Invention

[Means for Achieving the Object] That is, an opening / closing mechanism in a setback system for a screen or the like according to claim 1 is provided with an opening in a part of a wall surface, a decorative plate covering the opening is retracted, and a rear wall surface is located at this position. In a setback system where a screen, a whiteboard, etc. that were on standby are advanced, two of these plate-shaped members open and close along the guide rails laid on the machine frame provided at the rear of the wall surface. The opening / closing mechanism includes a motor, a drive pulley, and a guide roller in the frame, and the guide roller sandwiches the side surface of the guide rail, and the drive pulley contacts the side surface of the guide rail.

An opening / closing method using the opening / closing mechanism in the setback system for a screen according to claim 2 is:
In a setback system in which an opening is provided in a part of the wall surface, the decorative plate that covers this opening is retracted, and a screen, whiteboard, etc. waiting on the rear wall surface advance to this position Is opened and closed along a guide rail laid on the machine frame provided on the rear of the wall surface, and the opening / closing mechanism for this has a motor, a drive pulley and a guide roller in the frame, and the guide roller sandwiches the side surface of the guide rail. In addition, in the device in which the drive pulley contacts the side surface of the guide rail, power supply to the motor is stopped before the plate-shaped member having the two-piece structure reaches behind the opening. Then, the object of the invention is to be achieved by using the constitution of the invention described in each of these claims.

[0007]

According to the first aspect of the invention, the opening / closing mechanism includes the motor, the drive pulley, and the guide roller in the frame member,
Since the side surface of the guide rail is sandwiched by the guide rollers and the drive pulley contacts the side surface of the guide rail,
By rotating the drive pulley, the two plate-shaped members can be opened and closed smoothly, and no offensive noise is produced.

Further, according to the second aspect of the present invention, the power supply to the motor is stopped before the two plate-shaped members reach the rear of the opening, so that the plate-shaped members are subsequently driven by inertial force. As the motor progresses, the motor acts as a brake, and the propulsive force is gradually attenuated. For this reason, the speed becomes very gentle just before the two whiteboards and the like are fitted together, and there is no possibility of leaving a gap after the collision.
