Abstract

PURPOSE: To simplify a device by applying the constitution that a curtain is opened and closed on the operation of a motor in such a state as connected to a pulley, and manually independent of the motor, when the motor is disconnected from the pulley. CONSTITUTION: When a power supply for a motor 6 is turned on, augmented torque is transmitted to a pulley 4a and at the same time, torque is transmitted to another pulley 4b via a rotation transmission member 43. As a result, two drive belts 2 rotate and two leading runners 3a fitted thereto slide along a direction for nearing or parting from each along a curtain rail 1 to enable curtains 5a to be opened and closed like a Freuch door. Thus, the curtains 5a hooked to the runners 3a are opened and closed. When the motor 6 is stopped, both of an opening gear 64a and a closing gear 64 turn into a neutral state free from gearing with a torque transmission gear 62 and, therefore, the curtains 5a can be manually opened and closed. Namely, no clutch mechanism dedicated to a changeover operation is needed and a device is simplified.

A slit 14 is opened in the longitudinal direction in the partition wall 13 with 2,
The outer wall 15 of the runner sliding chamber 12 facing the slit 14 is also a rail member having a slit 16 formed in the longitudinal direction. Further, a projecting portion 17 is formed on the inner upper surface of the drive belt storage chamber 11, and rising portions 18 are formed on both edge portions of the slit 14. The cartel rail 1 is made of an extruded material such as aluminum or resin.

<C> Drive Belt As shown in FIGS. 2 and 3, the drive belt 2 is made of a flexible material such as urethane resin, and one surface thereof has a thickness which is different from that of the drive belt 2. Then, the tooth portion 21 having a high height is provided. Then, as shown in FIG. 2, the drive belt 2 is
To the left and right in the drive belt storage chamber 11 of the cart rail 1,
It is housed in a ring shape so that the tooth portion 21 is located inside.

<D> Leading runner The leading runner 3a, as shown in FIGS.
It consists of a part and a fixing jig. In the runner portion, a disk-shaped inner sliding piece 31 and an outer sliding piece 32 are joined by facing each other with a connecting member 33 so as to face each other at a predetermined interval.
On the outer surface of 2, a hooking piece 35 of the carten 5a having a hooking hole 34 is provided so as to project in a perpendicular direction. In addition, the internal sliding piece 31
Is connected to a fixing jig 37 via a connecting member 36 having an inverted L shape.

When the runner-3a is mounted, the carten is opened when the drive belt 2 is rotated clockwise (clockwise), and is closed when the drive belt 2 is rotated counterclockwise (counterclockwise).

Further, the fixing jig 37 is attached to one drive belt 2
If the fixing jig 37 functions as a connecting member, the work of joining the ends of the drive belt 2 can be avoided. The leading runner-3a may have a shape in which the outer sliding piece 32 is directly joined to the fixing jig 37 via the connecting member without providing the inner sliding piece 31.
Further, the runner portion of the leading runner-3a and the fixing jig 37 may be of a split type so as to be detachable. Further, when the driving belt 2 is a flat belt without the teeth 21, the fixing jig 37 is tightened with a screw or the like.
The drive belt 2 can be securely mounted.

<E> The runner-runner-3b, as shown in FIG. 1, is the head runner-3a.
The fixing jig 37 and the connecting member 36 are not provided, and only the runner portion is provided. The runner-3b is fitted into the slit 16 of the carten rail 1 to drive the drive belt 2
Glide independently of.

<F> Carten The carten 5a is made of various materials and is stretched between the carten rails 1. The connection between the carten 5a and the carten rail 1 is performed by hooking the leading runners 3a and 3b and both end edges of the carten 5a with hooks 51.

<G> Drive Mechanism Both ends of the drive belt 2 which is annularly housed in the carten rail 1 are wound around the pulleys 4a to 4d. Pulley 4a ~
4d are housed in housings 41a to 41d, respectively. Further, the pulleys 4a and 4b are connected to each other by a rotation transmission member 43 which covers the protective pipe 42. Protection pipe 4

The rotation transmitting member 43 may be a non-flexible rod or the like when the pulleys 4a and 4b are linearly connected to each other.
When connecting them in a curved shape, a flexible shaft or the like is used. Further, when the lengths of the two carter rails 1 are different from each other, they are connected by the rotation transmitting member 43.
By changing the number of teeth of the two pulleys 4a and 4b, the two leading runners-3a are moved at different speeds, and each carriage is moved.
The opening / closing operation of the carten 5a on the ten rail 1 side is completed at the same time.

<CHA> MOTOR As shown in FIG. 1, the rotational force transmission shaft 68 of the motor 6 is connected to the pulley 4a so that the rotational force of the motor 6 can be transmitted. . The outline of the motor 6 is shown in FIG. At the other end of the rotational force transmission shaft 68 connected to the pulley 4a, the rotational force transmission gear 62 is provided.

b is pivotally supported on both sides of the swing plate 65. Also,
The lower gear portion 63b of the center gear 63 is provided with a drive gear 6 on the coil side via an intermediate gear 66 and a required number of reduction gears 67.
The rotational force of 8 can be transmitted.

The operation of each gear is as follows. First, the drive gear 68 rotates, the rotational torque is increased via the reduction gear 67 group and the intermediate gear 66, and then the opening gear via the lower gear portion 63b of the central gear 63. The rotation is transmitted to 64a and the closing gear 64b. When the carten is opened, as shown in FIG. 5, the counterclockwise rotation is transmitted to the central gear 63, and the rocking plate 65 pressed against the central gear 63 follows the counterclockwise rotation by frictional force. It rotates, and the opening gear 64a meshes with the rotational force transmission gear 62. Since the opening gear 64a rotates in the clockwise direction, the rotational force transmission gear 62 rotates in the counterclockwise direction, and the pulley 4a is rotated in the counterclockwise direction via the rotational force drive shaft 61 to cover the cart. Can be opened.

In the case of closing the carten, the reverse of the above, as shown in FIG. 6, the clockwise rotation is transmitted to the central gear 63, and the oscillating plate 65 pressed against the central gear 63 follows the frictional force. Then, it rotates clockwise, and the closing gear 64b meshes with the rotational force transmission gear 62. Since the closing gear 64b rotates counterclockwise, the rotational force transmission gear 62 rotates clockwise, and the pulley 4a is rotated clockwise via the rotational force drive shaft 61 to rotate the cart. It can be closed.

FIG. 7 shows a neutral state in which neither the opening gear 64a nor the closing gear 64b meshes with the rotational force transmission gear 62. In such a neutral state, the motor 6 and the cart mechanism are separated, so that the cart can be manually opened and closed. In the neutral state of the gear, immediately after the operation of the motor 6 is stopped, a reverse rotation signal is momentarily transmitted to separate the opening gear 64a and the closing gear 64b from the rotational force transmission gear 62. Become.

In addition, using a spring or the like, the opening gear 64
A mechanical means for constantly urging a and the closing gear 64b to the neutral state is also conceivable. Further, instead of forcing the neutral state forcibly as described above, if the carten is manually opened / closed after the operation of the motor 6 is stopped, the rotational force transmission gear 62 is rotated by the force. Opening gear 64a or closing gear 6
Since 4b is naturally disengaged, it is possible to set it in a neutral state.

[0025]

The operation of the first embodiment will be described with reference to FIG. When the power of the motor 6 is turned on,
The increased rotational force is transmitted to the pulley 4a, and further the rotation is transmitted to the pulley 4b via the rotation transmission member 43. As a result, the two drive belts 2 rotate, and the two leading runners 3a attached to the drive belts 2 slide in the direction toward or away from the carten rail 1 to open the carten 5a in a double-door manner. It can be opened and closed in a shape. Then, the cover 5a hooked on the leading runner-3a and the runner-3b is opened and closed. When the motor 6 is stopped, the gear is in the neutral state as described above, so that the carten 5a can be opened and closed manually.
