Description

  The present invention relates to an interlocking transmission device for interlockingly rotating a plurality of drive shafts capable of transferring one or a plurality of shielding materials (curtain materials or the like), and a shielding device including the interlocking transmission device.

  As a typical example of a shielding device that suspends and supports a curtain material by a plurality of drive shafts, there is a curtain rail that opens and closes a double curtain material in the left-right direction. The curtain rail generally suspends and supports a double curtain material, for example, a thick drape curtain and a thin lace curtain on the indoor side and the outdoor side, respectively.

  Normally, in such a curtain rail, for example, when the drape curtain and the lace curtain are each opened and closed electrically, a motor is individually provided to independently realize the opening and closing drive of each curtain material.

  By the way, in the use form of a normal curtain rail, when the drape curtain is closed after the lace curtain and the drape curtain are fully open, the drape curtain is first closed after the lace curtain is also closed. Further, when the drape curtain is opened / closed from the fully closed state, the lace curtain is preferably maintained in the fully closed state. And when opening and closing a lace curtain from a fully open state, it is desirable to maintain a drape curtain in a fully open state.

  However, in a normal curtain rail, two operations are required to close the drape curtain and the lace curtain, which causes problems such as the operation burden on the operator, the cost of the two motors, and the control burden on each motor.

  In order to solve this problem, a hanger is provided on the top runner for the drape curtain, a hanger is provided on the front runner for the lace curtain, and the hanger and the hanger protrude from the side of each rail. An apparatus is disclosed that is configured such that when one curtain is opened, the other curtain opens together, and when the other curtain is closed, the other curtain is also closed by engagement / disengagement of the tool and the receiver (for example, Patent Document 1).

  In addition, an apparatus is disclosed in which a single motor is connected to two drive output shafts via a clutch, and the drape curtain and the race curtain are individually moved (see, for example, Patent Document 2).

  An example of another shielding device that suspends and supports a curtain material by a plurality of drive shafts is a roll curtain that opens and closes the curtain material vertically by two drive shafts. A roll-up roll curtain that can roll up a material with each drive shaft, or a roll-up roll curtain that can wind up a double-folded curtain material with two drive shafts (see, for example, Patent Document 3) ) A vertical two-axis winding roll curtain (see, for example, Patent Document 4) that allows one curtain material to be wound by two drive shafts in a vertical arrangement, or one curtain material in a horizontal arrangement. There is a horizontal two-axis winding roll curtain that can be wound by two drive shafts (see, for example, Patent Document 5).

Japanese Patent No. 4013096 Japanese Utility Model Publication No. 62-129984 Japanese Utility Model Publication No. 61-194090 US Pat. No. 5,682,937 U.S. Pat. No. 9,238,940

  Considering the actual usage of the curtain rail, when the drape curtain is closed when the lace curtain and the drape curtain are fully open, it is desirable to close the lace curtain at the same time, and the drape curtain with the lace curtain fully closed When opening and closing the lace curtain, it is desirable to maintain the lace curtain in a fully closed state. And when opening and closing a lace curtain in a state where a drape curtain is fully opened, it is desirable to maintain a drape curtain in a fully open state. Further, when the curtain rail is configured electrically, it is desirable to reduce the cost by reducing the control burden of each motor by using one motor.

  At this time, according to the technique of Patent Document 1, it is configured by one motor, and when one curtain is opened by engagement / disengagement of the hanging tool and the receiving tool, the other curtain is also opened and the other curtain is closed. The curtain and one of the curtains are both closed. However, it is necessary to make these hooks and receivers protrude from the side portions of the rails, and foreign matters such as dust are likely to enter the rails, resulting in quality problems. .

  Further, in the technique of Patent Document 2, it is possible to reduce the control burden by connecting to two drive output shafts via a clutch with one motor. There is a problem that a mechanism for connecting the clutch and the runner is required, resulting in an increase in apparatus cost.

  Further, normally, a shielding device that can open and close the curtain material with a plurality of drive shafts requires an interlocking transmission device to rotate each driving shaft in some way, and further, the interlocking transmission device is used as a shielding device. Since it is necessary to align the phases of the respective drive shafts when assembling, there is a problem that it generally takes time during assembly.

  This problem is also a problem with a roll curtain that opens and closes a curtain material with a plurality of drive shafts in addition to the case of a curtain rail. Further, when the number of curtain materials to be opened and closed increases, more drive shafts are required, and it becomes more difficult to align the phases of the drive shafts. This is a problem that occurs not only in the curtain material but also in a shielding device using a shielding material such as a shutter.

  In view of the above-described problems, an object of the present invention is to provide an interlocking transmission device for facilitating the phase alignment of a plurality of drive shafts capable of transferring one or a plurality of shielding materials and rotating the driving shaft, and the interlocking transmission device.

Attempts are made to mount the transmission shafts 19a and 19b of the interlocking transmission device 15 to be accommodated from below. At this time, each lock member 151 is placed in an unlocked state with respect to the main body 150. The transmission shaft 19a extends longer than the transmission shaft 19b by ΔL.

  Subsequently, as shown in FIG. 10B, the rotation operation unit 153 is adjusted from the outside by using a screw driver SD, and first, the transmission shaft 19a is engaged with the square hole 11a of the drive pulley 11 in the transfer device 2a. Let At this time, when the phase of the transmission shaft 19b and the corresponding drive pulley 11 is out of engagement phase angle, the tip of the transmission shaft 19b abuts on the input shaft end surface of the square hole 11a of the drive pulley 11, If phase alignment is not performed, the interlocking transmission device 15 cannot be installed in the transfer devices 2a and 3a. In this state, the transmission shaft 19b is simply pushed into the square hole 11a of the drive pulley 11 in the transfer device 3a by pressing the interlocking transmission device 15 while continuously adjusting the rotation operation portion 153 using the screw driver SD. Can be engaged. Therefore, when the transmission shaft 19a configured as the main engagement shaft is engaged with the corresponding drive pulley 11, the rotation operation unit 153 performs an external rotation operation on the drive pulley 11 corresponding to the transmission shaft 19b. It is designed to induce a match.
