Description

[Detailed description of the invention] (Industrial application field) The driving device of the hoisting shutter according to the present invention opens and closes the hoisting shutter with an electric mechanism, for example, when the electric mechanism breaks down or a power failure occurs. It can be opened and closed manually.

(Background of the Invention) It is widely practiced to provide a bay window at a window opening of a general house. In recent years, it has been proposed to provide a wind-up shutter for such a bay window. FIGS. 7 and 8 show a bay window with a wind-up shutter incorporating the drive device of the present invention. First, the structure and operation of the bay window with a wind-up shutter will be briefly described. I do.

Glass windows 1, 1 fitted to both right and left sleeves, and a sliding glass window 2 at the center (see FIG. 8; FIG. 7 shows a window fitted to fit for simplicity). ) Are provided with a wind-up type shutter 3 (FIG. 8) on the outside of each of the exit windows. At night or when going out, the shutter 3 is lowered to provide security or the like.

That is, on the upper outside of the glass window 1 and the glass shoji 2,
Winding drums 4 and 4 are provided respectively. The ends of the rotating shafts of the adjacent winding drums 4 and 4 are engaged with each other by bevel gears 5 and 5, and all the winding drums 4 and
4 rotate in synchronization. A driven pulley 6 is provided at one end (the right end in FIG. 7) of the winding drum 4 at the center.

On the other hand, a storage case 8 made by combining plywood or the like is fixed inside the roof portion 7 of the bay window, and a drive unit 9 having a built-in electric drive means 21 is provided inside the storage case 8. The drive pulley 11 fixed to the end of the drive shaft 10 of the drive unit 9 and the driven pulley 6
The belt 12 is stretched between them. Therefore, based on the energization of the electric drive means 21 of the drive unit 9, the winding drums 4, 4 can be rotated to raise and lower the shutter 3.

(Problems to be Solved by the Invention) Meanwhile, in the case of the conventional roll-up shutter with the bay window configured as described above, the electric shutter opening / closing mechanism due to the failure of the electric driving means 21 incorporated in the driving unit 9 and the like. In the event of a failure, the shutter 3 cannot be raised or lowered. Therefore, there is a demand for a structure that can manually raise and lower the shutter 3 even when the electric shutter opening / closing mechanism fails.

The driving device of the hoisting shutter according to the present invention has been devised in view of the above-described circumstances.

(Means for Solving the Problems) The drive device of the hoisting shutter of the present invention is for rotating the winding drum of the hoisting shutter provided on the outdoor side of the window device.

Such a drive device for a hoisting shutter according to the present invention includes a drive shaft provided substantially parallel to a driven-side rotation shaft of the winding drum, and a power supply between the drive shaft and the driven-side rotation shaft. A transmission member for performing transmission, a cylindrical casing having the drive shaft fixed to one end, an electric drive means housed in the casing, and rotating only a drive-side rotating shaft protruding from a distal end when energized; A coupling member that couples the side rotation shaft and the casing, a reduction mechanism having an input shaft and an output shaft irreversibly engaged with each other, a handle for manually rotating the input shaft, On the other hand, the base end of the electric drive unit is freely coupled to transmit the rotational force from the output shaft to the electric drive unit, and the electric drive unit is connected to the drive side rotation shaft with the rotation of the output shaft. Coupling machine that rotates to the center Provided with a door. The other end of the casing is rotatably supported around the coupling mechanism around the coupling mechanism.

(Operation) In the case of the shutter driving device of the present invention configured as described above, the shutter is normally raised and lowered based on the energization of the electric driving means. When the drive-side rotating shaft rotates based on the energization of the electric driving means, the rotation is transmitted to the winding drum via the coupling member, the casing, the driving shaft, and the transmitting member, and the winding drum is driven to rotate, The shutter is raised and lowered. Since the speed reduction mechanism is irreversible, the output shaft to which the base end of the electric drive means is connected via the connection mechanism does not move when the drive side rotation shaft rotates. Therefore, the electric drive unit itself does not rotate except for the drive side rotation shaft.

On the other hand, when the electric drive unit fails, the handle is manually operated to rotate the input shaft of the speed reduction mechanism. The rotation of the input shaft is transmitted to the electric drive unit via the output shaft of the reduction mechanism and the coupling mechanism, and rotates the entire electric drive unit. As a result, the rotation of the electric drive unit is transmitted to the drum via the drive-side rotation shaft, the coupling member, the casing, the drive shaft, and the transmission member, and the drum is rotationally driven,
The shutter can be moved up and down slowly.

(Embodiment) FIGS. 1 to 8 show an embodiment of a driving device for a hoisting shutter according to the present invention. As shown in FIGS. 7 and 8, a drum 4 of a wind-up shutter is provided above the window device and on the outdoor side of the glass shojis 2 and 2 constituting the window device. A drive shaft 10 of a drive unit 9 is provided on the upper side of the window device on the indoor side of the glass shojis 2 and 2 substantially in parallel with a driven-side rotation shaft 13 to which the drum 4 is fixed. The drive pulley 11 is fixed to the end of the drive shaft 10, and the driven pulley 6 is fixed to the end of the driven-side rotary shaft 13.
A belt 12, which is a transmission member, is stretched between them. The belt 12 allows power to be freely transmitted between the drive shaft 10 and the driven-side rotation shaft 13.

That is, the opening 24 is provided in the bottom plate 23 of the storage case 8 provided inside the roof 7 of the bay window. Also, this bottom plate 23
A first support bracket 27, which is a combination of a fixed bracket 25 and a displacement bracket 26, is provided at one end (right end in FIG. 1) of the opening 24 on the upper surface of the first bracket. And
The drive shaft 10 is rotatably supported by a bearing 28 supported by the displacement-side bracket 26 among them.

A pair of long holes 29 are formed in the displacement side bracket 26 in the indoor and outdoor directions (front and back directions in FIG. 1 and up and down directions in FIG. 2). Bracket 25
The screws 30, 30 that pass through the
Nuts 31 and 31 are screwed into a portion of the upper end portion protruding from the upper surface of the displacement side bracket 26.

On the other hand, a bent piece 32 is formed downward at the end of the fixed side bracket 25 on the indoor side (front side in FIG. 1, lower side in FIG. 2, left side in FIG. 3, right side in FIG. 4). ing. Then, an adjusting screw 33 is attached to a nut 34 fixed to the bent piece 32.
Is screwed in from the outdoor side, and the tip of the adjusting screw 33 abuts against the bent portion 36 of the receiving piece 35 fixed to the displacement-side bracket 26. For this reason, if the adjusting screw 33 is rotated while the nuts 31 are loosened to adjust the distance between the bent piece 32 and the bent portion 36, the displacement-side bracket 26 is moved relative to the fixed-side bracket 25. Displace the drive pulley 11
The tension between the belt 12 and the driven pulley 6 can be adjusted by changing the distance between the belt 12 and the driven pulley 6. After completing the adjusting operation, the nuts 31 are tightened.

The drive shaft 10 is fixed to the center of one end of a cylindrical casing 19 by a pair of coupling plates 18. Inside the casing 19, an electric drive means 21 is provided. The electric drive means 21 is configured by combining an electric motor main body and a speed reducer having an irreversible transmission mechanism. Then, the electric drive means 21 rotates the drive-side rotating shaft 20 protruding from the end thereof only when energized. When power is not supplied, the drive-side rotating shaft 20 does not rotate with respect to the main body of the electric drive means 21 due to external force. The drive-side rotating shaft 20 and the casing 19 are connected to each other by a connecting member 22 so that the casing 19 rotates with the rotation of the drive-side rotating shaft 20.

A second support bracket 37 is fixed to the other end (the left end in FIG. 1) of the opening 24. The holding bracket 39 is swingably supported by a vertical shaft 38 supported by the second support bracket 37, and the reduction bracket 40 is held by the holding bracket 39. When the tension of the belt 12 is adjusted by rotating the adjusting screw 33, the holding bracket 39 swings about the vertical shaft 38.

The reduction mechanism 40 has an input shaft 41 and an output shaft (not shown) irreversibly engaged with each other. Then, when the input shaft 41 is rotated, the output shaft rotates slowly. On the other hand, when a torsional force is applied to the output shaft from the output shaft side, the output shaft does not rotate. As the structure of such a speed reduction mechanism 40, various types of conventionally known mechanisms can be adopted. For example, it is possible to adopt a structure in which a worm wheel is rotated by a worm rotating with the rotation of the input shaft 41, and an output shaft concentric with the worm wheel is rotated.

Further, a base end of the electric drive means 21 (left end in FIG. 1).
Are coupled by a coupling mechanism in a state where the output shaft and the drive-side rotary shaft 20 are arranged concentrically with respect to the output shaft. That is, the cylindrical member 43 constituting the coupling mechanism is coupled to the output shaft, and the base end of the electric driving means 21 is coupled and fixed to the cylindrical member 43. The electric drive means 21 is rotated via the coupling mechanism including the tubular member 43 in accordance with the rotation of the output shaft.
For example, a sun gear may be fixed to the output shaft, a ring gear may be fixed to the inner peripheral surface of the tubular member 43, and a plurality of planetary gears may be provided between the ring gear and the sun gear. With this configuration,
Transmission of the rotational force from the output shaft to the cylindrical member 43 is performed via a planetary gear reduction mechanism. In this case, the coupling mechanism includes the planetary gear mechanism and the cylindrical member 43.

A holding ring 44 is fitted around the cylindrical member 43 so as to freely rotate with respect to the cylindrical member 43, and the holding ring 44 supports the other end of the casing 19. Therefore, the other end of the casing 19 is rotatably supported around the cylindrical member 43 constituting the coupling mechanism.

Further, the lower end of the input shaft 41 of the speed reduction mechanism 40 is connected to the upper end of the handle shaft 42 via the universal joint 14.
At the lower end of the handle shaft 42, a handle (not shown) for rotating the input end 41 is provided. The handle shaft 42 hangs downward from the opening 24 when necessary (when manually raising and lowering the shutter 3), but is lifted up to above the bottom plate portion 23 when unnecessary.
It is locked on a part of the bottom plate 23. For this reason, a locking member 45 as shown in FIGS. 5 and 6 is fixed to a part of the bottom plate portion 23, and an intermediate portion of the handle shaft 42 is locked to a grip portion 46 of the locking member 45. Be free.

Further, with the handle shaft 42 housed above the bottom plate portion 23, a cover plate 47 that can be opened and closed is provided in the opening 24 so as to close the opening 24. 48 and 48 are locking tools for locking the cover plate 47 to the bottom plate portion 23, respectively, and 49 is a key for opening and closing the cover plate 47, so that the cover plate 47 can enter and exit from the bottom surface of the cover plate 47. It is a knob freely provided.

In the drive device of the hoisting shutter of the present invention configured as described above, the shutter 3 is raised and lowered based on the energization of the electric driving means 21 at normal times. Electric drive means 21
When the drive-side rotation shaft 20 rotates based on the power supply to the motor, the rotation is transmitted to the casing 19 via the coupling member 22. Since the other end of the casing 19 is rotatably supported by the cylindrical member 43 via the holding ring 44, the casing 19 rotates with the rotation of the drive side rotation shaft 20. The drive shaft 10 fixed to the center of one end of the casing 19
The driven pulley 6 is driven to rotate via the drive pulley 11 and the belt 12, and the drum 4 is driven to rotate via the driven-side rotating shaft 13 to raise and lower the shutter 3.

At this time, a cylindrical member supporting the base end of the electric drive means 21
A torsional force is applied to 43 as a reaction force based on the rotation of the drive-side rotary shaft 20. However, since the reduction mechanism 40 in which the cylindrical member 43 is coupled to the output shaft is irreversibly configured by incorporating a worm or the like, the cylindrical member 43 is
It does not move when the drive side rotation shaft 20 rotates.

Further, when the electric driving means 21 fails, the cover plate 47 is removed, the handle shaft 42 is taken out from the opening 24 of the bottom plate portion 23, and the handle shaft 42 is hung downward. Then, the handle provided at the lower end of the handle shaft 42 is manually rotated. As a result, the speed reduction mechanism
The input shaft 41 of 40 rotates, and the entire electric drive means 21 rotates via the cylindrical member 43 connected to the output shaft of the speed reduction mechanism 40. The rotation of the electric drive means 21 is controlled by the drive-side rotation shaft 20,
Coupling member 22, casing 19, drive shaft 10, drive pulley 11,
The power is transmitted to the drum 4 via the belt 12, the driven pulley 6, and the driven-side rotating shaft 13. Then, the drum 4 is driven to rotate, and the shutter 3 can be moved up and down slowly but slowly.

(Effects of the Invention) Since the drive device of the hoisting shutter of the present invention is configured and operates as described above, it is possible to raise and lower the shutter even when the electric driving means is out of order, and to carry out the operation in the event of a failure or power failure. Minimum functions can be secured.
