Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides curtains for automobile windows or residential windows.
This invention relates to a curtain opening/closing device that can be opened and closed electrically and manually.

[Conventional technology]

As a conventional device of this type, for example, Japanese Patent Application Laid-Open No. 57-12
There is one disclosed in Japanese Patent No. 5714.

This device is attached via a hook to a hanging device that is movable along a rail fixed to the upper edge of the vehicle window.

The curtain is connected to the rail so that it can be opened and closed, and a loop-shaped belt is installed inside the rail with its width direction facing sideways.

The belt has holes drilled at equal intervals, and a drive gear driven by five motors meshes with these holes, and the belt is connected between the drive gear and a driven gear pivoted to the other end of the rail. It is hung and moved on a rail.

The hanger at the end of the curtain is formed with a gear wheel in the part located in the rail, which gear wheel can engage the belt and rotate and move. This gear has
A friction clutch is provided as a torque limiter.

When opening and closing the curtains, the belt is moved by the motor through the drive gear, so the gear moves with the belt without being rotated by the #*clutch to open and close the curtains, and also to open and close the curtains manually. The friction clutch then slips and the gear rotates on the belt, allowing the curtain to be opened and closed by hand.

[Problem to be solved by the invention]

In the above-mentioned device, the drive gear is equipped with a friction clutch, and the belt is installed horizontally in the width direction of the rail, so the cross-sectional shape of the rail becomes large. The appearance of the curtain is poor, and when the curtain is opened and closed manually, the friction clutch slips, making it difficult to open and close the curtain.

The present invention has been made in view of the conventional problems, and its purpose is to provide a curtain opening/closing device that has a simple configuration, has a small cross-sectional shape of the rail, and has a good appearance. be.

[Means to solve the problem]

In order to achieve the above object, the present invention has a base (3), side surfaces (4) that hang downward from both sides of the base (3), and a lower side surface (4) that is bent inward from the lower end of the side surfaces (4). 5), a support part (6) extending upward from the inner end of the lower surface (5), and left and right parts 1 formed between the base (3), the side surface (4), and the support part (6). The rail has a pair of storage parts (7a) and (7b), and has an approximately downward U-shaped cross section that opens downward.

It is characterized by comprising driving members (24) and (28) which are movable in the longitudinal direction along the storage parts (7a) and (7b) of 1) and to which the curtains are connected.

[For production]

When the motor (11) is not energized, the clutch (
I5) is in a non-transmission state 6 Therefore, the curtain (Kl) (K2) is manually moved in the opening/closing direction, and in conjunction with this, the belt (23) is moved to the rail (
1) Move the storage parts (7a) (7b) and remove the drive pulley (
17), the rotation is not transmitted to the output shaft of the motor (1), so the curtains (Kl) (K2)
It can be operated manually in the open or close direction.

When opening the curtains (Kl) (K2) electrically, energize the motor (11), rotate the output shaft (lla) in the forward direction, put the clutch (15) in the transmission state, and rotate the drive pulley (17) counterclockwise. When the driving members (24, 28) are moved along the rail (1) by rotating the belt (23), the curtains (Kl) (K2) move in the opening direction.

In addition, when closing the curtains (KL) (K2) electrically, the motor (11) is energized, the output shaft (lla) is reversed, the clutch (15) is placed in the transmission state, and the drive pulley (1

(31) has an almost upward U-shaped front shape, and its concave portion (
31a) in the longitudinal direction of the rail (1), a first drive runner that fits and interlocks with the coupled drive runner (24), and a base that extends downward from the opening (1a) of the rail (1); (31b) shows the first hook (K3) that is hooked to the upper edge of the right curtain (K1).
A shaft (33) is formed in the upper part of the pair of arms (31d) in the front and back direction.
A pair of left and right rollers (34) are pivotally mounted.

The roller (34) is movably supported on the protrusion (6a) of the rail (1).

(35) has the same shape as the first drive runner (31).

A second drive runner interlocking with the drive member (28), which is connected to the recess (
35a), base (35b) and left curtain (K2)
A hole (35c) into which the leading hook is hooked, and a roller (36) are provided.

(38) is hooked by the hooks (K3) of the left and right curtains (Kl) (K2), and the long flat surface of the rail (1) is moved over the protrusion (6) of the rail (1) by the roller (39). A plurality of free runners that can move freely along the direction.

(40) is a stopper located at the center of the rail (1) in the longitudinal direction, and when the curtain is closed, the first driving runner (31) and the second runner (35) come into contact with each other.

(41), (42), and (43) are rollers that guide the belt without loosening.

Next, the operation of the present invention will be explained.

The belt (23) is attached to the storage section (7a) of the rail (1) (
Since the width direction of the rail (1) is stored in the rail (7b) with its width facing the vertical direction, the width of the rail (1) becomes small, and the belt (23), coupling drive member (24), etc. ) is not exposed to the outside, so it looks good.

When the motor (11) is not energized, the clutch (
15), the magnet (13) is in the immersed state and is in a non-transmission state.

Therefore, the left and right curtains (Kl) (K2) are manually moved in the opening/closing direction, and in conjunction with this, the belt (23) moves the storage sections (7a) (7b) of the rail (1).
Even if the drive pulley (17) is rotated, the rotation is not transmitted to the output shaft (lla) of the motor (1), so the left and right curtains (Kl) (K2) can be manually and lightly moved from either side. It can be operated in the open or closed direction.

Further, by opening or closing either one of the left and right curtains (Kl) (K2), the other curtain can be opened and closed in conjunction with the opening and closing of either one of the left and right curtains (Kl) (K2).

When opening the curtains (Kl) (K2) electrically, the motor (11) is energized, the output shaft (lla) is rotated in the normal direction, the clutch (15) is in the transmission state, and the pinion (12c) and gear (17a) are When the drive pulley (17) is rotated counterclockwise via the belt (23) and the belt (23) is moved in the A direction, the coupled drive member (24) and the drive member (28) are moved in the opening direction away from each other. , the curtains (Kl) and (K2) each move in the opening direction.

In addition, when closing the curtains (Kl) (K2) electrically, the motor (11) is energized, the output shaft (lla) is reversed, the clutch (15) is placed in the transmission state, and the binion (12
c) Rotate the drive pulley (17) clockwise via the gear (17a), move the belt (23) in the B direction, and connect the coupled drive member (24) and the drive member (28).
When moved in the closing direction closer to each other, the curtains'' (
Kl) and (K2) can each move in the closing direction.

〔Effect of the invention〕

According to the present invention, the following effects are achieved.

(8) Since the motor (11) is provided with a clutch (15), the motor (11) is not interlocked with the manual opening/closing movement of the curtain, and the curtain can be opened and closed easily.

(b) Place the belt (23) in the storage section (7a) of the rail (1).
Since it is housed in (7b), it has a good appearance, the rail width can be narrowed, and narrow installations can be installed inside the board.
