Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a shutter winding drive mechanism.

[0002]

2. Description of the Related Art In a shutter opening / closing apparatus, the winding and rewinding of a shutter is performed by winding and rewinding in a storage box in a sleeve portion. Conventional driving mechanism is JP-B-38
-Wind the shutter body around the winding shaft as in No. 292
Or as described in JP-A-58-7083.
Means are a winding device by a chain traveling device. Again
As shown in FIG. 5 attached to the application specification , the shutter 11 is housed by a spiral guide rail 13 in a housing portion 14 connected to the guide rail 12 of the opening / closing portion, and its drive is attached to the upper portion of the shutter. The drive gear 16 meshed with the rack gear 15 winds or unwinds the inside of the box.

[Problems to be solved by the present invention]
JP-B-38- # 292 issue of the failure in a complex mechanism many costs
However, Japanese Patent Laid-Open No. 58-7083 has heavy running
It is difficult to drive the chain and there is a problem in driving noise. Also in FIG.
The mechanism attaches the mounting mechanism between the rack gear 15 of the shutter and the gear drive 16 provided in the drive inside the box on the shutter.
To run through a gear mechanism attached to one side of the part ,
The load on the running roller of the shutter causes a difference in running performance between the upper and lower parts of the shutter, and there is noise due to creaking.
There had difficulties impede uniform by oscillating exerted on the bottom, and lightweight running property. Further, a simple and effective means for reducing the cost was required. In order to solve these problems, an object of the present invention is to provide a power saving mechanism and a drive mechanism for reducing the load.

[0004]

As means for achieving the above object, a shutter is provided in a storage box 5 of the shutter device 1.
Vortex of upper guide rail 2 and lower guide rail 3
Winding parts 6 and 6 were provided and they were installed at the upper part in the storage box.
The drive gear of the driver 7 and the opening and closing direction of the storage box
Between the transmission gear 18 of the transmission shaft 10 and the transmission gear
And a large gear above and below the transmission shaft.
8, 8 near the guide rail of the storage box opening
Attach, between upper guide rail 2 and lower guide rail 3
A pipe frame for a shutter that runs suspended or
The large gears 8, 8 of the transmission shaft are engaged with the slats to
Wrap around the spiral part 6, 6 of the guide rail in the box
The gist is to take, rewind and open and close.

[0005]

The transmission gear of the transmission shaft provided near the guide rail in the opening of the storage box of the shutter and the driving of the driving body .
Daiki was axially supported horizontally in a vertical transmission shaft which is provided in the box which is rotated by the take over the chain belt between the gear
(A) abuts between the slat concave part attached to the shutter or the pipe attached in the vertical direction to suppress the swinging motion of the suspended shutter, and winds and rewinds it on the guide rail spiral part in the storage box. To open and close the shutter.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with respect to a winding drive mechanism of a pipe shutter.
Is a shutter composed of a pipe frame, and a traveling roller 4 or a pulley mounted on the upper guide rail 2 hangs a pipe frame 1 of the shutter on a support shaft of the pipe frame to slide and travel. 3 is the lower guide rail,
17 is a bearing shaft of the storage box 5 of the shutter device, 6,
6 is a guide rail spiral part provided in the storage box 5;
The driver was lower set through the bracket (not shown) or the like in the storage box 5 top 8,8 are close to the guide rails of the box opening the large gear pivotally attached to the upper and lower transmission shaft 10
Provide . The transmission shaft 10 is a pipe frame as shown in FIG.
Erect in the box in the same direction as the pipe shaft 1
10 transmission gear 18 and rotating gear of the driver 7 (not shown)
, Via a chain belt 9 wound around the belt . Large gear 8
Is attached to the transmission shaft 10 in the horizontal direction and the shutter device
It is mounted to engage with a pipe shaft or a recess in a slat . As shown in FIGS. 1 and 3, the large gears 8, 8 are provided above and below the pipes of the pipe frame in the direction in which the shutter travels.
The teeth of the large gear are directly engaged with the pipe to suppress the swinging motion of the pipe frame, and are sent to the guide rail spiral part 6 in the storage box for winding and storage. The shutter is sent out of the box by the reverse rotation of the drive motor.
In the above-described embodiment, the pipe shutter has been described. However, as for the slat shutter, the rotary gear is configured to contact the rotary gear above and below the concave portion of the slat to run the shutter.

[0007]

EFFECT application of the shutter driving mechanism, since the above-mentioned winding drive mechanism, the hanging mechanism provided in the upper portion of the shutter of struts TsuSo the running rollers in the first simplified, also in FIG. 5
As described above, since the gear mechanism attached to the shutter has been reduced in labor, it is effective in reducing the weight of the shutter and the processing cost. Second, the large gears 8 above and below the transmission shaft correspond to the shutter frame.
Lightweight running of the shutter because the shutter is fed in contact with the shutter
In line favor . Also suppresses the shaking movement under the shutter
Roller feed during shutter run
There is an advantage that the lines are smooth and friction noise is reduced .
