Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a stopper device when a hanging door (hanging drive door) is opened.

[0002]

[Prior Art]

 The hanging door is hung on a rail and runs, and the opening is opened and closed. Therefore, a running tool is attached to the upper end of the hanging door and the running tool rolls on the rail. can do. A self-closing device is provided on the rail side so that the opened hanging door can be closed automatically, and a braking device (damper) is attached to prevent the hanging door from being closed by shock. There is. The braking device is capable of adjusting the closing speed of the hanging door, so that the hanging door is gently closed and does not cause the bounce phenomenon. In this way, an open hanging door can be closed automatically, but it is sometimes necessary to keep the hanging door open, and therefore a full-open stopper device is provided.

FIG. 3 shows a conventional stopper device. The running tool (b) attached to the upper end of the hanging door (a) moves the rail (c) to move the above hanging door (a). When opened / closed and opened, the traveling tool (b) comes into contact with the door stop (d) fixed to the rail side and stops, and the hanging door (b) that is pulled by the self-closing device and tries to close is stopped ( E) and keep it open. By the way, a cushioning material is attached to the contact surface of the door stop (d), but when the hanging door (a) is strongly opened, the running tool (b) contacts the door contact (d). When you do, an impact sound is generated. In addition, the hanging door (a) that hits the cushion material may bounce off and close without being locked by the stopper (e). In other words, even when hitting the door stop (d), all the kinetic energy of the hanging door (a) is not absorbed, but only the direction of movement is reversed and it bounces.

[0004]

[Problems to be Solved by the Invention] As described above, the conventional stopper device for a hanging door has the above problems. The problems to be solved by the present invention are these problems, and to provide a stopper device which eliminates the impact sound when opened and prevents the bounce phenomenon.

[0005]

[Means for Solving the Problems]

 The stopper device for the hanging door of the present invention eliminates the impact sound at the time of opening and prevents the bounce phenomenon. Configure to loosen and stop. Therefore, the motion energy of the hanging door is completely absorbed by the stopper device and the energy to bounce off is lost.

By the way, the stopper device of the present invention has the following features. The stopper used in the conventional stopper device is used as it is and is composed of a V-shaped or U-shaped leaf spring. A conventional door stop is not used, but a braking plate that swings around a fulcrum is provided, and a spring is attached to the braking plate, which is tilted at a predetermined angle. The open hanging door moves there, and the running tool hits the brake plate and pushes up the tip of the brake plate. That is, as the traveling tool moves, it pushes up the braking plate to deform the spring, and the kinetic energy of the hanging door is gradually absorbed and stopped.

As described above, the brake plate is pushed up by the movement of the hanging door, but a hit is installed at a predetermined position to regulate the push-up height of the brake plate. In this case, the braking plate is not only pushed up as the traveling tool moves, but also the rotation of the roller of the traveling tool that abuts on the braking plate is suppressed by friction torque. Further, the stopper device of the present invention is not limited to the case where the running tool is directly locked to the braking plate and the stopper to restrict the movement of the hanging door, and a separate member may be provided and locked to the hanging door. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 1 shows a hanging door device equipped with a stopper device according to the present invention, in which the hanging door 1 is hung on a rail 2 and running tools 3, 3 provided on both sides of the upper end of the hanging door 1 roll along the rail 2. You can move around. In the figure, 4 is a self-closing device, 5 is a damper, and the wire 6 of the self-closing device 4 is fixed to the hanging door 1 and always applies tension in the closing direction. The tip of the piston rod 7 extending from the damper 5 hits the hanging door 1 to control the speed when the hanging door 1 is closed. Each of these devices is also provided in the conventional hanging door device and may be used as it is.

The stopper device of the present invention is the part shown in A of the same figure, which eliminates the impact sound of the opened hanging door and prevents the bounce phenomenon. FIG. 2 shows the details of the portion A, and the stopper 8 is arranged at a predetermined position as usual and is locked to the running tool 3 of the hanging door 1 which is pulled back and closed. The stopper 8 is a leaf spring and is pushed up every time the traveling tool 3 passes, but when the traveling speed is low, the stopper 8 cannot be pushed up and stops. Here, the shape of the stopper 8 is not limited to the V-shaped spring shown in the figure, but it must be a shape that allows the traveling tool 3 to pass and is pushed up in association with the passage.

A braking plate 9 is attached next to the stopper 8, and the braking plate 9 is tilted at a predetermined angle and can swing about a fulcrum 10. The tip 11 moves up and down with the rocking. A spring 12 is attached to the braking plate 9, and if the tip end portion 11 is pushed up, the spring 12 is compressed and deformed, and the tip end portion 11 of the braking plate 9 pushed up to a certain height hits. It abuts 13 and its movement is blocked.

The braking plate 9 is arranged such that the fulcrum 10 side is high and the tip 11 side is low, and the roller 14 of the traveling tool 3 that moves along the rail 2 when the hanging door 1 is opened is the braking plate 9 described above. Then, the braking plate 9 is pushed up. The running tool 3 does not stop instantaneously even if it comes into contact with the braking plate 9, and goes straight as it is, but as it moves, it pushes up the tip 11 of the braking plate 9 and compresses the spring 12. Therefore, the energy required for compressing the spring 12 is consumed, the speed of the hanging door 1 is gradually reduced, and finally it stops. The suspended door 1 is returned by the action of the tension from the self-closing device, the traveling tool 3 hits the stopper 8 and stops again, and the suspended door 1 is kept open. Since the hanging door 1 stopped by hitting the braking plate 9 has no rebounding force, the returning speed is slow and it does not have enough kinetic energy to push up the stopper 8 to pass it.

By the way, when the roller 14 of the traveling tool 3 contacts the braking plate 9 and moves further, the roller 14 pushes up the braking plate 9 to compress and deform the spring 12, and at the same time, the reaction force from the spring 12 As a result, a pressure acts between the roller 14 and the braking plate 9, and a friction torque acts to prevent the rotation of the roller 14 due to the movement. As a result, the motion energy of the hanging door 1 is immediately absorbed. Of course, when the energy consumed by the compressive deformation of the spring 12 and the friction torque of the roller 14 cannot be stopped by absorbing the kinetic energy of the hanging door 1, the tip 11 of the braking plate 9 hits the contact 13. As a result, the movement of the running gear 3 is blocked by the contact 13.

As described above, in the stopper device of the present invention, the fulcrum side is raised to pivotally support the braking plate, and the spring is attached to the braking plate and the tip end portion is pushed up to compress and deform the spring. Further, the following effect can be obtained by providing a contact for restricting the push-up height and further disposing a stopper at a predetermined distance from the fulcrum.

[0014]

[Effect of the device]

 Since the stopper device of the present invention pivotally supports the brake plate with which the roller of the traveling member abuts so as to be swingable, if the roller hits the brake plate and moves further, it is attached to the brake plate. Since the spring is compressed and frictional torque is generated between the spring and the brake plate to suppress rotation, the hanging door stops immediately. In this case, the kinetic energy of the hanging door is consumed by the compressive deformation of the spring and the friction torque of the roller, so that the rebound phenomenon does not occur.

Therefore, even if the suspended door is stopped by the action of the tension from the self-closing device and hits the stopper, the stopper cannot be pushed up because the return speed is low and the suspended door is opened. To be kept in a state. Moreover, since the hanging door consumes kinetic energy and stops while moving, no impact noise is generated.
