[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a braking device mounting structure for a sliding door that employs a rack and pinion mechanism.

[0002]

[Prior art]

 FIG. 3 shows a sliding door device. The sliding door (a) is hung on an upper rail (c) by means of hanging tools (b) and (b) attached to its upper end. A roller is pivotally supported by the hanging tool (b), and the sliding door (a) can be opened and closed by rolling the upper rail (c). In addition, (d) in the figure is a self-closing device that has a built-in spring spring, and always biases the spring force that winds the wire (e). Therefore, if the wire (e) is attached to the hanger (b), the sliding door (a) will be pulled by the wire (e) to close the entrance / exit.

Further, (f) in FIG. 3 is a damper composed of an air cylinder. Although the rod (g) of the damper (f) is extended, when the sliding door (a) is closed, the above-mentioned hanger ( The contact (h) attached to (b) comes into contact with the tip of the rod (g) to retract the rod (g). When the rod (t) retracts, the air in the cylinder flows through the small nozzle, so the closing speed of the sliding door (a) is suppressed and the sliding door (a) closes gently.

As described above, the sliding door device having the self-closing device is equipped with the braking device so that the sliding door can be closed quietly. Although the braking device shown in FIG. 3 is a damper composed of an air cylinder, a braking device using a rack and pinion mechanism is also used. That is, the rack is attached to the upper rail side, the pinion is provided on the sliding door side, and the pinion engages with the rack before the sliding door is closed. If a torque damper is attached to the pinion, the brake engages with the rack at the same time and the brake acts to suppress the closing speed of the sliding door.

By the way, whether to use an air cylinder or a rack-and-pinion as a braking device for the sliding door is determined each time, and it is necessary to have a structure that can be freely selected. However, in reality, the form of the braking device was determined at the design stage of the sliding door, and it is impossible to change it later.

[0006]

[Problems to be solved by the present invention]

 As described above, the conventional braking device has the above problems. The problem to be solved by the present invention is this problem, and provides a mounting structure of a braking device capable of mounting a rack-pinion type braking device to a sliding door device equipped with an air cylinder type braking device. .

[0007]

[Means for Solving the Problems]

 The present invention has a common mounting structure of a sliding door device, and has a mounting structure of a braking device which can be mounted on both an air cylinder type braking device and a rack-pinion type braking device. is there. Therefore, a mounting member is attached to a suspender that pivotally supports the roller, a torque damper is mounted on the mounting member, and a pinion is provided on the shaft of the torque damper.

The rack is attached along the rail base and meshes with the pinion. The rack is attached above the pinion via a rack receiver. There are various types of mounting members for the torque damper, and there is no particular limitation. However, if the mounting members are removed, the contact (h) shown in FIG. I can. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 1 shows an embodiment of the present invention and shows a braking device for a sliding door using a rack and pinion mechanism. The basic structure of the sliding door device is the same as that shown in FIG. 3, and the hangings 2 are attached to both upper end sides of the sliding door 1, and the roller 3 is attached to the hangings 2. Is rotatably supported. Then, the roller 3 is placed on the upper rail 4 and rolls to open and close the sliding door 1. Here, the upper rail 4 is attached to the rail base 3 arranged at the upper part of the frontage.

As shown in FIG. 1A, the suspension 2 has a U-shaped cross section, and a mounting member 5 is screwed to the outside of the U-shaped suspension 2, and a torque damper is attached to the tip of the mounting member 5. 6 is attached. The torque damper 6 is a component that requires a predetermined torque when the shaft is rotated, and a generally commercially available one is used. This can be done by turning the screw 7 provided at the center for adjusting the generated torque.

A pinion 8 is attached to the shaft of the torque damper 6, and a rack 9 is horizontally installed on the rail base 13. The rack 9 is attached to a rack receiver 10 provided on a rail base 13, and the pinion 8 meshes with the rack 9. The rack 9 is located above the pinion 8. Therefore, the upper part of the pinion 8 meshes with the rack 9, and the height of the rack receiver 10 is adjusted to optimize the meshing condition with the pinion 8. There is.

Here, the rack 9 is provided at a position where the pinion 8 can be engaged before the sliding door 1 is closed, and the pinion 8 of the sliding door 1 traveling at a predetermined speed is attached to the rack 9. The brake works by meshing. That is, the pinion 8 rotates by meshing with the rack 9 and at the same time rotates the shaft of the torque damper 6, but a certain torque resistance is generated and the brake is applied, and the traveling speed of the sliding door 1 is lowered. It will be.

Here, the pinion 8 and the rack 9 are made of resin, and a part of the tip of the rack 9 projects from the rack receiver 10, and the tip of the rack 9 can be flexibly deformed. Therefore, when the pinion 8 traveling in a stopped state meshes with the rack 9, the rack 9 slightly bends to assist the meshing.

FIG. 2 shows another embodiment of the present invention in which the shape of the mounting member 11 is different. The hanger 2 is also U-shaped in cross-sectional shape, but a U-shaped stopper 12 is fitted and attached to one side of the hanger 2, and the mounting member 11 is attached to the stopper 12. Has been done. A torque damper 6 is also attached to the tip of the attachment member 11, and a pinion 8 is provided on the shaft of the torque damper 6. Therefore, if the contact (h) shown in FIG. 3 is attached instead of the attaching member 11, an air cylinder type braking device can be constructed. As described above, although the sliding door braking device of the present invention is the rack-pinion type braking device, it can be easily changed to the air cylinder type braking device. Can be obtained.

[Effect of device]

 The mounting structure of the braking device of the present invention is such that a mounting member is mounted on a hanging member of a sliding door and a Turkish damper is mounted on the tip of the mounting member, and the basic structure of the sliding door device is the same. That is, the braking device can be an air cylinder type braking device or a rack-pinion type braking device. The rack of the rack-pinion type braking device of the present invention is located above the pinion, its height can be adjusted, and optimum engagement with the pinion can be brought about. By protruding from the receiver, it flexes and deforms, and the pinion meshes smoothly. Furthermore, since the rack is attached to the rack receiver, it can be easily replaced.
