It is a simple opening/closing device to use.

<Prior Art> Conventionally, various automatic opening/closing devices have been installed at the entrances and exits of buildings. For example, a motor and a belt are connected to a sliding door suspended from a rail, and this motor is connected to various sensors and switches, including a matsuto switch and an infrared sensor, and the sliding door is opened and closed by rotating the motor forward and backward. It is something.

<Problems to be solved by the invention> However, in conventional switchgear, the opening and closing operations are performed by rotating the motor in forward and reverse directions, and therefore the durability of the motor must be doubled. In addition, the electrical system was complicated due to the provision of various sensors and switches. Furthermore, most conventional devices are installed at entrances and exits to the outside of buildings, and are intended for large, heavy doors that take into account wind pressure and waterproofing, so the opening/closing devices themselves are large, complex, and expensive. It was hot. Moreover, the motor and opening/closing device generate slight noises and vibrations, and their large size and weight pose a high risk in the event of an accident. Furthermore, the installation and adjustment of the conventional switchgear is complicated and requires specialized skills, resulting in high costs in terms of labor costs.

<Means for Solving the Problems> The present invention suspends a sliding door via a sliding bracket mechanism on a rail housed inside an upper cross member, and connects one end of the bracket mechanism and a motor to a drive source. The sliding door is opened by communicating with the drive holding mechanism by the transmission member, and the other end of the bracket mechanism is also connected with the control mechanism by the connecting member, and the sliding door is opened while being controlled by the braking/closing mechanism. It is designed to be closed.

<Operation> The bracket mechanism suspends the sliding door and slides on the rail, and the forward rotation of the motor of the drive holding mechanism is connected to the bracket mechanism by the transmission member to open the sliding door, which is connected by the connecting member. The sliding door can be closed while suppressing inertia using the brake closing mechanism.

When the solenoid 37 is opened in the direction of the arrow in FIG. 1 and reaches the position of the reed switch 38, the reed switch 38 is turned off and the motor 35 starts to move slightly, and the timer device is activated to maintain the open state for, for example, 2 seconds. Configure it as follows.

A U-shaped wire pedestal 39 is further fixed on the horizontal surface 9 of the angle plate 4 of the bracket mechanism 1. Ropes and other connecting members including wires 40 from this wire base 39 are connected to the brake closing mechanism 3 installed in the upper cross member b on the door edge side. This control mechanism 3 is attached to a board 41 provided in the upper cross member b, and its specific configuration is shown in FIGS. 5 to 7.

Further, the drive holding mechanism 2 and the brake closing mechanism 3 are housed in the upper cross member b, and the drive belt 27 and the wire 40 are connected to the bracket mechanism 1, respectively.
All you have to do is plug in the electrical circuit connectors and connect them.

The sliding door equipped with the opening/closing device of the present invention is opened and closed as follows.

When the push button switch 36 is pressed, the motor 35 rotates in the forward direction, and therefore the drive pulley 32 rotates.
The drive belt 27 meshing with the teeth 34 of the pulley 32 and the teeth 31 moves, and the sliding door a, which is integrated with the belt 27 via the bracket mechanism 1, moves to the first sliding door a.
It is opened in the direction of the arrow in the figure, and the wire 40 wound around the drum 45 in the brake closing mechanism 3 is extended. At this time, since the main shaft 43 does not rotate even if the drum 45 rotates, the spring 53 is gradually tightened by the rotation of the drum 45. Sliding door a moves further and solenoid 37 switches to reed switch 3.
When the position 8 is reached, the reed switch 38 is turned off, the motor 35 enters a slight movement, and the sliding door a is opened for the time set by the timer. The timer goes off,
When the torque of the motor 35 decreases below the repulsive force of the spring 53, the sliding door a is pulled back by the repulsive force of the spring 53. However, since the braking oil 55 is present between the braking plate 54 and the rear plate 49, the inertia is suppressed and the sliding door does not return suddenly and does not collide with the sliding door a.

The return speed of the sliding door a is adjusted by the brake closing mechanism 3.
This is done by sliding the operating part 52 to remove the pawl 50 from the ratchet gear 44, inserting a square rod or screwdriver into the recess 46, turning the main shaft 43, and tightening or loosening the spring 53. I can do it.

<Effects of the invention> In summary, the present invention provides a drive holding mechanism at one end of the interior of the upper cross member, a brake closing mechanism at the other end, and connects the drive holding mechanism and the sliding door bracket mechanism using a transmission member. At the same time, the braking/closing mechanism and the bracket mechanism of the sliding door are connected by a connecting member such as a wire, and the driving of the drive holding mechanism causes the transmission member to slide the sliding door toward the open side, and the braking/closing mechanism is closed by stopping the drive of the drive holding mechanism. Since the sliding door was made to slide toward the closing side via the connecting material,
The corner brake closing mechanism, drive holding mechanism, etc. can be integrated into a unit, making installation work, position adjustment, maintenance inspection, etc. extremely easy, and even non-specialist engineers can easily install it inside the upper cross member. can. In addition, since sliding doors slide frequently, the drive holding mechanism and brake closing mechanism operate violently, resulting in damage and frequent maintenance inspections. However, according to the present invention, the drive holding mechanism and brake closing mechanism are Because they are located at each end of the material, if one mechanism is damaged or requires maintenance, there is no need to work on the other mechanism, significantly reducing maintenance and repair time. The amount of time the sliding door is left open is extremely short, and there is no need to waste effort, time, or money on replacing or repairing parts, which is of great practical value.
