Abstract

(57) [Summary] [Purpose] Labor saving of the shutter winding drive mechanism. [Mechanism] A mechanism provided so that a gear mounted on a winding section transmission shaft of a winding drive mechanism that opens and closes a shutter frame suspended on a guide rail is engaged with the shutter frame to drive winding.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shutter winding drive mechanism.

[0002]

[Prior art]

 In the shutter opening and closing device, the winding and unwinding of the shutter is performed by revolving the guide rail in the sleeve box of the sleeve. Conventionally, as shown in FIG. 5, the drive mechanism of the shutter 11 is such that the shutter 11 is housed by the spiral guide rails 13 in the housing 14 connected to the guide rails 12 of the opening and closing parts, but the drive is attached to both sides of the shutter. The drive gear 16 meshed with the rack gear 15 winds or unwinds the inside of the box.

[0003]

[Problems to be solved by the present invention]

 In the conventional drive mechanism described above, the attachment mechanism between the shutter and the gear provided in the drive section in the box is caused to travel via the gear mechanism attached to the shutter, so that friction noise between gears during traveling or the traveling roller of the shutter There was a drawback that the load also increased. The purpose of the task is to reduce the load and labor saving mechanism to solve these problems.

[0004]

[Means for Solving the Problems]

 As means for achieving the above object, a shutter winding drive mechanism is provided in which a gear mounted on a transmission shaft of a winding portion is engaged with a shutter frame to drive winding.

[0005]

[Action]

 The transmission gear installed near the guide rail in the storage opening of the shutter is directly engaged with the flat recess of the shutter or between the pipes to wind up the spiral in the storage and then rewind to open and close the shutter.

【Example】

 An embodiment of the present invention will be described with reference to a winding drive mechanism of a pipe shutter. In the drawings, reference numeral 1 is a shutter composed of a pipe frame, and a roller 4 or a pulley is used to suspend the pipe frame 1 from an upper guide rail 2 for sliding travel. . 3 is a lower guide rail, 5 is a storage box of the shutter device, 6 is a guide rail spiral portion, 7 is a drive motor, 8 is a chain belt 9 wound around the rotation shaft of the drive motor, and is placed above and below the transmission shaft 10. It is a rotating gear mounted on the shaft. As shown in FIG. 3, the rotary gear has tooth portions sequentially inserted and engaged between the pipe frames in the traveling direction of the shutter to send the pipe frame into the storage box for winding and storage. The shutter is sent out from the box by the reverse rotation of the drive motor. In the above-mentioned embodiment, the pipe shutter is explained, but in the slat shutter, the gear is engaged with the gear in the connection recess of the slat to drive the shutter. That is, as for the driving means, the means for carrying out is to directly engage the drive gear with the shutter device and wind it up to the storage part.

[0007]

【effect】

 In the shutter drive mechanism of the present application, the drive traveling by the guide rails of the shutter is a mechanism in which the gear pivotally mounted on the transmission shaft of the drive motor is directly engaged between the slats of the shutter device or the pipes for traveling. Since the rack mechanism installed on both sides of the shutter is a simple mechanism that saves labor, it is extremely effective in reducing processing costs. At the same time, the noise due to the turning friction between the gears is eliminated, and the load on the turning roller is reduced, which is very useful for improving the running function.
