Description

[Technical field]

[0001] The present embodiment relates to an operating device for an opening / closing device having an opening / closing body. [Background technology]

[0002] Conventionally, as this type of opening and closing device, the one shown in the following Patent Document 1 has been known. The opening and closing device shown in Patent Document 1 has an operating shaft that rotates when an operating force is transmitted thereto, a clutch that is rotatable integrally with the operating shaft and slidable in the axial direction on the operating shaft, and a first transmission member that transmits driving force to a first drive shaft and a second transmission member that transmits driving force to a second drive shaft, which are disposed on both axial sides of the clutch, respectively, and the sliding direction of the clutch is determined by the rotation direction of the operating shaft, and the clutch sliding on the operating shaft engages with one of the transmission members, so that the rotation of the operating shaft is transmitted to one of the drive shafts via one of the transmission members.

[0003] According to such an opening and closing device, by selecting the operating direction of a single operating cord for transmitting an operating force to the operating shaft, the drive shaft to be driven can be switched to operate different opening and closing bodies.

[0004] [Patent Document 1] Patent No. 5548013 Summary of the Invention [Problem to be solved by the invention]

[0005] Some opening / closing devices having two opening / closing bodies, including the above opening / closing device, can be operated with one operation cord not only for the raising operation but also for the lowering operation. Specifically, the opening / closing body can be lowered by its own weight by operating the operation cord to switch the state of the stopper that can restrict the rotation of the first drive shaft or the second drive shaft from a rotation restricting state to a rotation allowing state. At this time, since the rotation from the first drive shaft or the second drive shaft is also transmitted to the pulley around which the operation cord is wound, there is a problem that the operation cord rotates together with the opening / closing body as it lowers by its own weight, resulting in co-rotation. In addition, such co-rotation due to the descent by its own weight can naturally occur even in a single-type opening / closing device having one opening / closing body and one drive shaft.

[0006] The present invention has been made to solve the above-mentioned problems, and has an object to provide a technique capable of preventing co-rotation. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, one aspect of the present invention is an operating device for operating a first drive shaft that drives a first moving member of an opening and closing device and a second drive shaft that drives a second moving member of the opening and closing device, the operating device comprising: a rotation transmission part that rotates when a rotational driving force is transmitted from a pulley that is rotated by an operating member and moves to one side or the other side in the direction of the rotation axis depending on the direction of rotation; a first engagement transmission part that engages with the rotation transmission part when the rotation transmission part moves toward the one direction side, and transmits the rotational driving force to the first drive shaft by rotating integrally with the rotation transmission part in the engaged state, and releases the engaged state when the rotational driving force from the first drive shaft is transmitted; and a second engagement transmission part that engages with the rotation transmission part when the rotation transmission part moves toward the other direction side, and transmits the rotational driving force to the second drive shaft by rotating integrally with the rotation transmission part in the engaged state, and releases the engaged state when the rotational driving force from the second drive shaft is transmitted. Effect of the Invention

[0008] According to the present invention, it is possible to prevent co-rotation. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] <First embodiment> Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, an opening and closing device to which the present invention is applied to a pleated screen having two types of screens that can be raised and lowered as an opening and closing body will be described as an example. In this embodiment, the surface facing the room when the opening and closing device is installed will be referred to as the front, the surface facing the outside of the room as the back, the direction consisting of the front and back as the front-rear direction, and the longitudinal direction of the opening and closing device as the left-right direction. In this specification and drawings, components having substantially the same functions will be given the same reference numerals to avoid redundant description.

[0011] (Overall composition) First, the overall configuration of the opening and closing device according to this embodiment will be described. Fig. 1 is a front view showing the configuration of the opening and closing device according to this embodiment, and Fig. 2 is a schematic plan view perspective view thereof. Note that Fig. 1 shows the opening and closing device in a state in which the bottom rail is lowered to the lowest position, and only the inside of the head box is shown.

[0012] As shown in Figures 1 and 2, the opening and closing device 1 of this embodiment comprises a head box 2, a bottom rail 31 as a first movable member, two lifting cords 32 formed in the form of strings or tapes, a screen 33 as a first opening and closing body, an intermediate bar 41 as a second movable member, two dimmer cords 42 formed in the form of strings or tapes, a screen 43 as a second opening and closing body, and an operation unit 5.

[0013] The head box 2 is formed in a substantially rectangular parallelepiped shape that defines an accommodation space therein, and is fixed to a window frame (not shown) or the like via a plurality of brackets 21. The head box 2 accommodates a first drive shaft 201A, two first winding drums 202A, a first stopper 203A, a first brake 204A, a second drive shaft 201B, two second winding drums 202B, a second stopper 203B, a second brake 204B, an interlocking gear 205, and a lower limit 206.

[0014] The first drive shaft 201A, the two first winding drums 202A, the first stopper 203A, and the first brake 204A constitute a first drive system that moves the bottom rail 31 up and down. The second drive shaft 201B, the two second winding drums 202B, the second stopper 203B, and the second brake 204B constitute a second drive system that moves the intermediate bar 41 up and down. The interlocking gear 205 is configured to interlock the second drive system with the first drive system under a predetermined condition. In this embodiment, the first drive system is arranged on the rear side, and the second drive system is arranged on the front side, and the first drive system and the second drive system are arranged side by side with their positions different from each other in the front-rear direction. For example, the first drive system and the second drive system may be arranged side by side with their positions different from each other in the vertical direction, and the arrangement of the first drive system and the second drive system may be reversed in the front-rear direction or the vertical direction.

[0015] The first drive shaft 201A and the second drive shaft 201B are each a rectangular columnar member extending in the left-right direction, and are rotatably supported with their axial centers oriented in the left-right direction within the head box 2. Here, the axial center of the first drive shaft 201A is located at the same position as and rearward of the axial center of the second drive shaft 201B in the up-down direction, and the positions of the axial centers are different in the front-rear direction.

[0016] The two first winding drums 202A are each inserted through the first drive shaft 201A so as to rotate integrally with the first drive shaft 201A, and one end of the corresponding one of the two lift-down cords 32 is connected to the first winding drums 202A so as to be able to be wound and unwound. The two second winding drums 202B are each inserted through the second drive shaft 201B so as to rotate integrally with the second drive shaft 201B, and one end of the corresponding one of the two light control cords 42 is connected to the second winding drums 202B so as to be able to be wound and unwound.

[0017] The first stopper 203A restricts the rotation of the first drive shaft 201A in the unwinding direction. The second stopper 203B restricts the rotation of the second drive shaft 201B in the unwinding direction. The first stopper 203A and the second stopper 203B are configured to be switchable between a state in which the rotation of the first drive shaft 201A and the second drive shaft 201B is restricted and a state in which the rotation is permitted, respectively.

[0018] The first brake 204A reduces the rotation speed of the first drive shaft 201A in the unwinding direction. The second brake 204B reduces the rotation speed of the second drive shaft 201B in the unwinding direction. The first brake 204A and the second brake 204B reduce the rotation speed of the first drive shaft 201A and the second drive shaft 201B, respectively, to reduce the impact force generated when the bottom rail 31 and the intermediate bar 41 are lowered to the lower end position.

[0019] The bottom rail 31 is connected to the other ends of the two lifting / lowering cords 32, is supported by hanging from the head box 2 so as to be located at the lowest end of the opening / closing device 1, and is a member formed to be long in the left-right direction. The intermediate bar 41 is connected to the other ends of the two light control cords 42, and is supported by hanging from the head box 2 so as to be located between the head box 2 and the bottom rail 31 in the up-down direction, and is a member formed to be long in the left-right direction.

[0020] The screen 33 is an opening / closing body whose upper end is connected to the underside of the intermediate bar 41 and whose lower end is connected to the upper surface of the bottom rail 31, formed in a pleated shape that can be folded up and down, and through which the two lift-down cords 32 are partially inserted in the vertical direction. The screen 43 is an opening / closing body whose upper end is connected to the underside of the head box 2 and whose lower end is connected to the upper surface of the intermediate bar 41, formed in a pleated shape that can be folded up and down, and through which the two light control cords 42 are partially inserted in the vertical direction.

[0021] The lower limit 206 supports the other end of each of the first and second drive shafts 201A, 201B, and regulates the amount of the lifting cord 32 unwound by the first winding drum 202A to a preset maximum unwinding amount in conjunction with the rotation of the first drive shaft 201A. The maximum unwinding amount is adjustable, which allows the lower limit position of the bottom rail 31 to be set.

[0022] 2, the operation unit 5 is provided at one of the left and right ends of the head box 2, in this embodiment, at the right end in the figure, and a first drive shaft 201A and a second drive shaft 201B are inserted through the main body case 50. The operation unit 5 has an endless operation cord 51 configured as, for example, a ball chain, and rotates the first drive shaft 201A and the second drive shaft 201B so as to raise and lower the bottom rail 31 and the intermediate bar 41 in response to an operator's lifting and lowering operation of the operation cord 51. Specifically, when the operation cord 51 is pulled in one direction, the bottom rail 31 rises, and when it is pulled in the other direction, the intermediate bar 41 rises.

[0023] In the opening and closing device 1 according to the present embodiment, when the bottom rail 31 is raised, and the operation cord 51 of the operation unit 5 is pulled a predetermined distance so that the pulley 52 (see FIG. 3) described later rotates a predetermined amount in one direction (a direction to raise the bottom rail 31) and then released, the first stopper 203A releases the rotation restriction on the first drive shaft 201A, and the bottom rail 31 descends to the bottom end position due to its own weight, as shown in FIG. 1. The same is true for the intermediate bar 41, and when the intermediate bar 41 is raised, and the operation cord 51 is pulled a predetermined distance so that the pulley 52 rotates a predetermined amount in the other direction (a direction to raise the intermediate bar 41) and then released, the second stopper 203B releases the rotation restriction on the second drive shaft 201B, and the intermediate bar 41 descends to the bottom end position due to its own weight.

[0024] (Device configuration of operation unit 5) The configuration of the operation unit 5 will be described below. Fig. 3 is an exploded perspective view of the operation unit in the opening and closing device according to this embodiment. Fig. 4 is a bottom view of the clutch mechanism in the operation unit, and Fig. 5 is a cross-sectional view taken along line AA thereof. Fig. 6 is a perspective view showing a cylindrical member and a second transmission member in the clutch mechanism. Fig. 7 is a perspective view showing a state in which a clutch spring is attached to the cylindrical member, and Fig. 8 is a perspective view showing a state in which a cam member is attached to the cylindrical member. Fig. 9 is a schematic vertical cross-sectional view showing the configuration of a main body case in the operation unit.

[0025] As shown in FIG. 3, the operation unit 5 includes a pulley 52, an intermediate gear 53, an input gear 54, an input shaft 55, first and second clutch receivers 56A, 56B, first and second output shafts 57A, 57B, and a clutch 6 within a main body case 50.

[0026] Pulley 52 is rotatably supported within main body case 50 with operation cord 51 wound around its circumferential surface, and rotates in response to an operator pulling down operation cord 51. Pulley 52 is formed with gear portion 521, whose axis is concentric with pulley 52 and which is located on the inner side in the left-right direction (left side in the figure) and engages with first gear portion 531 of intermediate gear 53.

[0027] The intermediate gear 53 is rotatably supported within the main body case 50, and has a first gear portion 531 and a second gear portion 532 formed on the left-right inner side of the first gear portion 531. The first gear portion 531 meshes with the gear portion 521 of the pulley 52. ​​The second gear portion 532 is concentric with the first gear portion 531 and has a smaller diameter than the first gear portion 531, and meshes with the input gear 54. The input gear 54 is journaled on the input shaft 55 so as to be rotatable together with the input gear 54. Therefore, the rotation of the pulley 52 is transmitted to the input gear 54 via the intermediate gear 53, and is input from the input gear 54 to the input shaft 55.

[0028] The input shaft 55 is an elongated member whose axial direction faces the left-right direction, and in this embodiment, its axis is concentric with the first drive shaft 201A. The left-right outer end of the input shaft 55 is formed in a square shape and is fitted to the input gear 54 so as to be rotatable together with the input gear 54, and the second clutch receiver 56B is inserted into a cylindrical portion adjacent to the square portion to support the second clutch receiver 56B so as to be rotatable relative to the input gear 54. The input shaft 55 is rotatably supported by a cylindrical protrusion formed at the tip of the square portion being fitted into a hole (not shown) provided in the case. On the other hand, the left-right inner end of the input shaft 55 is formed in a cylindrical shape, and the first clutch receiver 56A is inserted into the cylindrical portion to support the first clutch receiver 56A so as to be rotatable relative to the input gear 54. In addition, a protrusion 551 protruding in the radial outward direction extends along the axial direction on the peripheral surface of the cylindrical portion adjacent to the cylindrical portion. As shown in FIG. 5, a plurality of protrusions 551 are formed so as to be spaced apart from each other along the circumferential direction. By forming a plurality of protruding parts 551, guide grooves 552 are formed between the protruding parts 551. The input shaft 55 rotates when the rotation of the pulley 52 is input via the input gear 54, and this rotation is switched and transmitted to either the first drive shaft 201A or the second drive shaft 201B by a clutch mechanism consisting of first and second clutch receivers 56A, 56B and the clutch 6.

[0029] The first and second clutch receivers 56A, 56B, which form part of the clutch mechanism, are formed in a hollow disk shape and are arranged so that their axes are concentric with the input shaft 55. One end 563 of the first clutch receiver 56A is inserted into an opening 553 of the input shaft 55 and supported so as to be rotatable relative to the input shaft 55, and the second clutch receiver 56B is supported so as to be rotatable relative to the input shaft 55 through which the input shaft 55 is inserted. As shown in Figs. 3 and 4, the first and second clutch receivers 56A, 56B have a plurality of projections 561 having inclined surfaces inclined relative to the circumferential direction formed on their opposing surfaces. In this embodiment, the inclined surfaces of the plurality of projections 561 formed on each of the first and second clutch receivers 56A, 56B are formed on the counterclockwise direction side of the projections 561 when viewed from the opposing surface side.

[0030] The first clutch receiver 56A is connected to the first output shaft 57A on the inner side in the left-right direction so as to be rotatable together with the first output shaft 57A. The first output shaft 57A is formed in a hollow cylindrical shape, and the first drive shaft 201A is fitted into the hollow portion so as to be rotatable together with the first output shaft 57A. Therefore, the rotation of the first clutch receiver 56A can be output from the first output shaft 57A to the first drive shaft 201A.

[0031] The second clutch receiver 56B has a gear portion 562 formed on the outer side in the left-right direction. The gear portion 562 meshes with a gear portion 571 formed on the outer end of the second output shaft 57B in the left-right direction. As a result, the rotation of the second clutch receiver 56B is transmitted to the second output shaft 57B via the gear portion 571. The second output shaft 57B is formed in a hollow cylindrical shape, and the second drive shaft 201B is fitted into the hollow portion so as to be rotatable together with the second output shaft 57B. Therefore, the rotation of the second clutch receiver 56B can be output from the second output shaft 57B to the second drive shaft 201B.

[0032] As shown in Fig. 4, the clutch 6, which is a part of the clutch mechanism, is disposed between the first clutch receiver 56A and the second clutch receiver 56B, and is journaled on the input shaft 55 so as to be reciprocable on the input shaft 55 along the axial direction (the direction of the rotation axis). When the clutch 6 moves toward the first clutch receiver 56A and engages therewith, a first engagement state is established in which the rotational driving force of the input shaft 55 can be transmitted to the first drive shaft 201A, and when the clutch 6 moves toward the second clutch receiver 56B and engages therewith, a second engagement state is established in which the rotational driving force of the input shaft 55 can be transmitted to the second drive shaft 201B. The first and second engagement states will be described in detail later.

[0033] As shown in FIG. 3, the clutch 6 has first and second transmission members 61A and 61B, a cylindrical member 62, a clutch spring 63, a cam member 64, and steel balls 65.

[0034] As shown in Figs. 3 and 4, the first and second transmission members 61A and 61B are supported by the input shaft 55 so as to be rotatable together with the input shaft 55, through which the input shaft 55 is inserted. The second transmission member 61B has a hollow disk-shaped disk portion 611B and a substantially cylindrical fitting portion 612B provided on the inner side of the disk portion 611B in the left-right direction. The disk portion 611B has a plurality of protrusions 613 having an inclined surface inclined with respect to the circumferential direction formed on the facing surface facing the second clutch receiver 56B. The inclined surface of each of the plurality of protrusions 613 is formed on the counterclockwise direction side of the protrusion 613 when viewed from the facing surface side. The fitting portion 612B is formed in an uneven shape with a part of its peripheral surface recessed in correspondence with the peripheral wall shape of the cylindrical portion of the input shaft 55 in which the protrusion portion 551 and the guide groove 552 are formed, and is fitted to surround the cylindrical portion of the input shaft 55 so as to be rotatable together with the fitting portion 612B. Moreover, the axial length of the fitting portion 612B is formed to be shorter than the guide groove 552, so that the second transmission member 61B is able to slide along the guide groove 552 in the axial direction.

[0035] The first transmission member 61A has a hollow disk-shaped disk portion 611A and a plurality of fitting portions 612A provided on the left-right inner side of the disk portion 611A. The disk portion 611A has a plurality of protrusions 613 having an inclined surface inclined with respect to the circumferential direction formed on the surface facing the first clutch receiver 56A, similar to the disk portion 611B. The plurality of fitting portions 612A are plate-shaped members that extend in the axial direction and are spaced apart from each other in the circumferential direction, and as shown in FIG. 5, are fitted to the outer circumferential surface of the fitting portion 612B of the second transmission member 61B so as to be integrally rotatable. Therefore, the first transmission member 61A and the second transmission member 61B are integrated parts together with the cylindrical member 62, the clutch spring 63, and the cam member 64, as described later, and can rotate integrally with the input shaft 55 and can also slide axially relative to the input shaft 55.

[0036] The protrusions 613 of the first and second transmission members 61A and 61B engage with the protrusions 561 of the opposing clutch receivers, thereby bringing about an engaged state in which the clutch 6 rotates integrally with the clutch receivers. The engagement of the first transmission member 61A with the first clutch receiver 56A brings about the first engaged state described above, and the engagement of the second transmission member 61B with the second clutch receiver 56B brings about the second engaged state described above.

[0037] In this embodiment, the length between the tips of the projections 613 of the first and second transmission members 61A and 61B, that is, the axial length L1 of the clutch 6 shown in FIG. 4, is formed to be shorter than the length L2 between the tip of the projection 561 of the first clutch receiver 56A and the tip of the projection 561 of the second clutch receiver 56B. Therefore, when either the first or second engaged state is in effect, the other state is not in effect at the same time. Note that FIG. 4 shows a clutch mechanism in which the clutch 6 is not engaged with either the first or second clutch receiver 56A or 56B, and the projection 561 and the projection 613 are close to each other, and thus in a disengaged state that is neither the first nor the second engaged state. In the disengaged state, the clutch 6 is located approximately midway between the first and second clutch receivers 56A and 56B.

[0038] 3 and 5, the cylindrical member 62 is formed in a hollow cylindrical shape, and the fitting portion 612A of the first transmission member 61A and the fitting portion 612B of the second transmission member 61B are inserted into the hollow portion and journaled by them. As shown in FIG. 6, a fitting groove 621 is formed in a part of the outer circumferential wall of the cylindrical member 62, into which a protrusion 614 formed on the inner circumferential wall of the disk portion 611B of the second transmission member 61B fits. The protrusion 614 fits into this fitting groove 621, so that the cylindrical member 62 is fixed to the second transmission member 61B so as to be rotatable together with the second transmission member 61B. Therefore, the cylindrical member 62 can rotate together with the first and second transmission members 61A and 61B in response to the rotation of the input shaft 55.

[0039] As shown in Figs. 3, 5 and 7, the clutch spring 63 is spirally wound around the outer circumferential surface of the cylindrical member 62 and is fastened to the cylindrical member 62 in a manner that tightens the cylindrical member 62. Hereinafter, such a state will be referred to as a clutch fastened state. In this clutch fastened state, the clutch spring 63 can rotate integrally with the cylindrical member 62. On the other hand, when the clutch spring 63 is relaxed (expanded in diameter) and the clutch fastened state is released, the clutch spring 63 becomes rotatable relative to the cylindrical member 62, that is, the cylindrical member 62 rotates freely relative to the clutch spring 63. Hereinafter, the state in which the clutch fastened state is released will be referred to as a clutch released state, and the clutch released state will be described in detail later. In addition, both ends 631, 632 of the clutch spring 63 are bent radially outward.

[0040] As shown in Fig. 3 and Fig. 5, the cam member 64 is formed in a hollow cylindrical shape, and the cylindrical member 62 around which the clutch spring 63 is wound is inserted into the hollow portion and journaled therein. As shown in Fig. 8, the outer peripheral wall of the cam member 64 is provided with insertion holes 641, 642 through which both ends 631, 632 of the clutch spring 63 are inserted individually. In the clutch-engaged state, the clutch spring 63 rotates together with the cylindrical member 62 in response to the rotation of the input shaft 55, so that either one of the both ends 631, 632 can abut against either wall surface of the insertion holes 641, 642, and thus the cam member 64 can rotate integrally with the cylindrical member 62 via the clutch spring 63. On the other hand, in the clutch-released state, the cylindrical member 62 rotates idly with respect to the clutch spring 63.

[0041] As shown in Fig. 4, the cam member 64 has a cam groove 643 formed on its outer circumferential wall, which extends obliquely with respect to the circumferential direction, specifically, from the front side on the outer left-right direction to the back side on the inner left-right direction. A steel ball 65 is slidably fitted into the cam groove 643, and the steel ball 65 is immovably fixed at a position corresponding to the cam groove 643 in the lower part of the main body case 50, as shown in Fig. 9. Therefore, when the cam member 64 rotates in response to the rotation of the input shaft 55, the cam groove 643 slides on the steel ball 65, and the cam member 64 can move in the axial direction while rotating along the inclination of the cam groove 643. Therefore, the cam member 64 can move back and forth linearly along the axial direction in response to the rotation direction of the input shaft 55.

[0042] (Operation of operation unit 5) The operation of the clutch mechanism described above will now be described. Figure 10 is a diagram for explaining the operation of the clutch mechanism in the first engaged state and clutch engagement state, and Figure 11 is a diagram for explaining the operation of the clutch mechanism in the first engaged state and clutch release state. Figure 12 is a diagram for explaining the operation of the clutch mechanism in the second engaged state and clutch engagement state, and Figure 13 is a diagram for explaining the operation of the clutch mechanism in the second engaged state and clutch release state. These figures are bottom views of the clutch mechanism and its surroundings.

[0043] In the disengaged state or the second engaged state shown in FIG. 4, when the input shaft 55 is rotated in the counterclockwise direction CCW as viewed from the input gear 54 side, the clutch 6 rotates in the CCW direction together with the input shaft 55. At this time, since the clutch is in the engaged state, the clutch spring 63 rotates in the CCW direction together with the cylindrical member 62, and one end 631 of the clutch spring 63 abuts against a wall surface 641a (see FIG. 8) of the insertion hole 641 of the cam member 64, and by biasing this, the cam member 64 rotates integrally with the cylindrical member 62 and the clutch spring 63. In response to the rotation of the cam member 64, the cam groove 643 slides against the steel ball 65, and the clutch 6 moves to one axial side, here, the first clutch receiver 56A side. In this state, the other end 632 of the clutch spring 63 does not abut against the circumferential surface of the insertion hole 642 of the cam member 64. After the cam member 64 rotates a predetermined amount and moves axially to one side, the projection 561 of the first clutch receiver 56A and the projection 613 of the first transmission member 61A come into contact with each other at their axially horizontal surfaces without inclined surfaces, as shown in Fig. 10, and engage to be able to transmit a rotational driving force. This brings the clutch mechanism into the first engaged state.

[0044] In the first engaged state, as shown in FIG. 10, the steel ball 65 is located at one end of the cam groove 643, and further rotation of the cam member 64 in the CCW direction is restricted by the steel ball 65. In this state, when the input shaft 55 is further rotated in the CCW direction as shown in FIG. 11, the clutch spring 63 rotates further in the CCW direction together with the cylindrical member 62, and the one end 631 of the clutch spring 63 further presses the wall surface 641a of the insertion hole 641. Since the cam member 64 is in a state in which the rotation in the CCW direction is restricted, the clutch spring 63 is relaxed. This state in which the clutch spring 63 is relaxed is the above-mentioned clutch release state, and the cylindrical member 62 and the like rotate freely relative to the cam member 64. Therefore, in the clutch mechanism in the clutch release state, the rotation of the cam member 64 stops, and the rotational driving force of the input shaft 55 can be transmitted to the first clutch receiver 56A via the first transmission member 61A.

[0045] In addition, in the clutch released state, when the input shaft 55 rotates in the reverse direction, i.e., clockwise CW as viewed from the input gear 54 side in the first engagement state as described above, one end 631 of the clutch spring 63 moves away from the wall surface 641a, causing the clutch spring 63 to contract in diameter, and the other end 632 of the clutch spring 63 abuts against the wall surface 642a (see Figure 8) of the insertion hole 642 in the cam member 64, allowing the clutch to transition from the clutch released state to the clutch engaged state.

[0046] On the other hand, in the disengaged state or the first engaged state, when the input shaft 55 rotates clockwise CW as viewed from the input gear 54 side, the clutch 6 rotates CW together with the input shaft 55 as shown in FIG. 12. At this time, since the clutch is in the engaged state, the clutch spring 63 rotates CW together with the cylindrical member 62, and the other end 632 of the clutch spring 63 abuts against the wall surface 642a of the insertion hole 642 in the cam member 64, and the cam member 64 rotates integrally with the cylindrical member 62 and the clutch spring 63. In response to the rotation of the cam member 64, the cam groove 643 slides against the steel ball 65, and the clutch 6 moves to the other axial side, here, the second clutch receiver 56B side. In this state, the one end 631 of the clutch spring 63 does not abut against the circumferential surface of the insertion hole 641 of the cam member 64. After the cam member 64 rotates a predetermined amount and moves to the other axial side, the projection 561 of the second clutch receiver 56B and the projection 613 of the second transmission member 61B come into contact with each other and engage to transmit the rotational driving force, as shown in Fig. 12. This puts the clutch mechanism into the second engaged state.

[0047] In the second engaged state, as shown in FIG. 12, the steel ball 65 is located at the other end of the cam groove 643, and further rotation of the cam member 64 in the CW direction is restricted by the steel ball 65. In this state, when the input shaft 55 is further rotated in the CW direction as shown in FIG. 13, the clutch spring 63 rotates in the CW direction together with the cylindrical member 62, and the other end 632 of the clutch spring 63 further presses the wall surface 642a of the insertion hole 642 in the cam member 64. Since the cam member 64 is in a state in which the CW rotation is restricted, the clutch spring 63 is relaxed and the clutch is released. The clutch mechanism in the clutch released state can transmit the rotational driving force of the input shaft 55 to the second clutch receiver 56B via the second transmission member 61B without transmitting it to the cam member 64.

[0048] Next, the operation of the operation unit when the clutch mechanism is in the first and second engagement states will be described. Fig. 14 is a diagram for explaining the operation of the operation unit when the clutch mechanism is in the first engagement state, and Fig. 15 is a diagram for explaining the operation of the operation unit when the clutch mechanism is in the second engagement state. These figures are bottom views of the operation unit 5.

[0049] As shown in FIG. 14, when the clutch mechanism is in the first engagement state, the input shaft 55 is rotated in the CCW direction, and the rotational driving force of the CCW rotation is transmitted to the first drive shaft 201A through the path indicated by the reference symbol R1 in the figure. Specifically, the first transmission member 61A of the clutch 6 rotates integrally with the input shaft 55, and the rotational driving force is transmitted to the first clutch receiver 56A that is in an engagement state with the first transmission member 61A. As a result, the rotational driving force is transmitted to the first output shaft 57A via the first clutch receiver 56A, and is output to the first drive shaft 201A. The first drive shaft 201A to which the rotational driving force of the CCW rotation is transmitted rotates the first winding drum 202A in the CCW direction, and the first winding drum 202A winds up the lifting cord 32 in response to the rotation, thereby lifting the bottom rail 31.

[0050] On the other hand, as shown in Fig. 15, when the clutch mechanism is in the second engaged state, the input shaft 55 is rotated in the CW direction, and the rotational driving force of the CW rotation is transmitted to the second drive shaft 201B via the path indicated by the symbol R2 in the figure. Specifically, the second transmission member 61B of the clutch 6 rotates integrally with the input shaft 55, and the rotational driving force is transmitted to the second clutch receiver 56B that is in an engaged state with the second transmission member 61B. As the second clutch receiver 56B rotates in the CW direction, the second output shaft 57B having a gear portion 571 that meshes with the gear portion 562 of the second clutch receiver 56B rotates in the CCW direction, and the rotational driving force of the CCW rotation is output from the second output shaft 57B to the second drive shaft 201B. The second drive shaft 201B to which the rotational driving force for CCW rotation is transmitted rotates the second winding drum 202B in the CCW direction, and in response to this rotation, the second winding drum 202B winds up the light control cord 42 and lifts the intermediate bar 41.

[0051] Next, the operation of the operation unit 5 when the bottom rail 31 and the intermediate bar 41 are each lowered will be described. Fig. 16 is a diagram for explaining the operation of the operation unit when the bottom rail is lowered, and Fig. 17 is a diagram for explaining the operation of the operation unit when the intermediate bar is lowered. These figures are bottom views of the operation unit 5.

[0052] When the clutch mechanism is in the first engaged state, the bottom rail 31 is raised, and then the operating cord 51 is pulled a predetermined distance so that the pulley 52 rotates in one direction (CCW rotation) and then released, the bottom rail 31 descends to the lowest position due to its own weight, as described above. At this time, the first winding drum 202A rotates in the direction to unwind the lifting / lowering cord 32 (CW rotation), and the first drive shaft 201A also rotates CW in response to this rotation.

[0053] As shown in FIG. 16, the rotational driving force of the CW rotation from the first drive shaft 201A follows the path indicated by the symbol R3 and is transmitted to the first clutch receiver 56A. When the first clutch receiver 56A starts to rotate in the CW direction, the projection 561 of the first clutch receiver 56A and the projection 613 of the first transmission member 61A are disengaged. More specifically, when the operating cord 51 is pulled a predetermined distance so that the pulley 52 rotates in one direction (CCW rotation) and then released, the first drive shaft 201A rotates in the CW direction in the first engagement state, and the rotational driving force due to this rotation is transmitted to the first transmission member 61A via the first clutch receiver 56A. As a result, the clutch 6 slides while rotating along the inclination of the cam groove 643, so that the clutch 6 can be pushed out in the direction of separation together with the first transmission member 61A in response to the CW rotation of the first clutch receiver 56A, that is, moved to the right in the figure. 16 shows the state (disengaged state) immediately after this separation movement. In this state, the first transmission member 61A is disengaged from the first clutch receiver 56A, and the second transmission member 61B is not engaged with the second clutch receiver 56B. The rotational driving force of the first drive shaft 201A is not transmitted to the clutch 6, and therefore is not transmitted to the input shaft 55 and, by extension, to the pulley 52.

[0054] On the other hand, when the clutch mechanism is in the second engaged state, the intermediate bar 41 is operated to rise, and then the operating cord 51 is pulled a predetermined distance so that the pulley 52 rotates in the other direction (CW rotation) and then released, the intermediate bar 41 descends to the lowest position due to its own weight, as described above. At this time, the second winding drum 202B rotates in the direction to unwind the light control cord 42 (CW rotation), and in response to this rotation, the second drive shaft 201B also rotates CW.

[0055] As shown in FIG. 17, the rotational driving force of the CW rotation from the second drive shaft 201B follows the path indicated by the symbol R4 and is transmitted to the second clutch receiver 56B as a CCW rotation. When the second clutch receiver 56B starts to rotate in the CCW direction, the projection 561 of the second clutch receiver 56B and the projection 613 of the second transmission member 61B are disengaged. More specifically, when the operating cord 51 is pulled a predetermined distance so that the pulley 52 rotates in the other direction (CW rotation) and then released, the second drive shaft 201B rotates in the CW direction in the second engagement state, and the rotational driving force due to this rotation is transmitted to the second transmission member 61B via the second clutch receiver 56B. As a result, the clutch 6 slides while rotating along the inclination of the cam groove 643, so that the clutch 6 can be pushed out in the direction of separation (leftward in the figure) together with the second transmission member 61B. FIG. 17 shows the state (disengaged state) immediately after this separation movement. In this state, the second transmission member 61B is disengaged from the second clutch receiver 56B, and the first transmission member 61A is not engaged with the first clutch receiver 56A, so that the rotational driving force of the second drive shaft 201B is not transmitted to the clutch 6, and therefore is not transmitted to the input shaft 55 or to the pulley 52.

[0056] According to the present embodiment described above, it is possible to prevent the rotational driving force from the first and second drive shafts 201A, 201B from being transmitted to the pulley 52, and to prevent co-rotation. Since co-rotation can be prevented, it is possible to avoid a state in which the operating cord 51 continues to rotate when the bottom rail 31 or the intermediate bar 41 is lowered, thereby improving the design and achieving noise reduction.

[0057] According to this embodiment, the clutch mechanism can be shared between the first and second drive shafts 201A and 201B, so that the number of parts can be reduced and costs can be reduced compared to a configuration in which a clutch mechanism is provided on each drive shaft. Also, since the cam groove 643 is formed in the cam member 64 and the clutch 6 can reciprocate in the axial direction between the first and second clutch receivers 56A and 56B, it is possible to prevent the clutch 6 from engaging with the first and second clutch receivers 56A and 56B and rotating together. Also, since the positions of the first and second clutch receivers 56A and 56B are fixed and in the engaged state, the steel ball 65 is located at the end of the cam groove 643 to restrict the rotation of the cam member 64, i.e., the movement of the clutch 6 is restricted, it is possible to prevent unexpected disengagement with the clutch 6 and to perform stable operation.

[0058] According to this embodiment, since the clutch 6 is located approximately between the first and second clutch receivers 56A, 56B in the disengaged state, the distance from the clutch 6 to each clutch receiver can be approximately equalized, and the axial size can be reduced. Furthermore, by appropriately designing the extension position of the cam groove 643 of the cam member 64 and the inclination angle with respect to the axial direction, the integral rotation of the cam member 64 and the input shaft 55 can be released at any position. Therefore, for example, as described above, the integral rotation of the cam member 64 and the input shaft 55 can be released at a position where the rotation of the cam member 64 is restricted (the first engaged state or the second engaged state), and the rotation of the input shaft 55 can be transmitted to either one of the first and second drive shafts 201A, 201B.

[0059] In this embodiment, the first moving member moved by the rotation of the first drive shaft 201A and the second moving member moved by the rotation of the second drive shaft 201B are the bottom rail 31 and the intermediate bar 41, which are respectively moved in the vertical direction, but the moving direction of the first moving member and the second moving member may be in any direction, and the first moving member and the second moving member may be arranged in front and rear and move up and down or left and right, respectively. In addition, although the description has been given using a pleated screen as an example of the opening and closing device, the present invention can be applied to various opening and closing devices such as blinds, curtains, partitions, shutters, sashes, windows, etc., such as horizontal blinds, vertical blinds, roll screens, honeycomb screens, roll-up curtains, and accordion doors, as long as they have first and second moving members and can be operated by an operation unit.

[0060] <Second embodiment> In the first embodiment, an opening and closing device was described in which the present invention is applied to a twin-type pleated screen equipped with two screens 33, 43. In the present embodiment, an opening and closing device will be described in which the present invention is applied to a single-type pleated screen equipped with only one screen 33.

[0061] Fig. 18 is a front view showing the configuration of the opening and closing device according to this embodiment, and Fig. 19 is a schematic plan view perspective view showing the configuration of the opening and closing device according to this embodiment. Fig. 20 is an exploded perspective view of an operation unit in the opening and closing device according to this embodiment. As shown in Figs. 18 and 19, the opening and closing device 1' according to this embodiment does not include the intermediate bar 41, the dimmer cord 42, the screen 43, and the second drive shaft 201B, the two second winding drums 202B, the second stopper 203B, the second brake 204B, and the interlocking gear 205, which are the second drive system related to these, and is different in configuration from the opening and closing device 1 according to the first embodiment in that it includes an operation unit 5' instead of the operation unit 5.

[0062] Since the opening / closing device 1' does not have a second drive system, the operation unit 5' does not have the second clutch receiver 56B and the second output shaft 57B, which are members related to the second drive system, as shown in FIG. 20, compared with the operation unit 5 according to the first embodiment. Since the operation unit 5' does not have the second clutch receiver 56B, the input shaft 55 of the operation unit 5' is formed with an axial length shorter than the input shaft 55 of the operation unit 5. This allows the left-right length of the operation unit 5' to be shorter than that of the operation unit 5. In addition, the operation unit 5' has a clutch 6' instead of the clutch 6. Since the operation unit 5' does not have the second clutch receiver 56B, the disk portion 611B of the second transmission member 61B of the clutch 6' does not have a protrusion 613 for engaging with the second clutch receiver 56B. Therefore, the clutch mechanism of the operation unit 5' does not enter the second engaged state according to the first embodiment.

[0063] (Operation of operation unit 5') The operation of the clutch mechanism of the operation unit 5' described above will be described. Figures 21 to 23 are diagrams for explaining the operation of the clutch mechanism in the opening and closing device according to this embodiment when it is in a disengaged state and the clutch is in a fastened state, the operation of the operation unit when the clutch mechanism is in the first engaged state, and the operation of the operation unit when the bottom rail is operated to be lowered. These figures are bottom views of the clutch mechanism and its periphery.

[0064] As shown in FIG. 21, when the input shaft 55 is rotated counterclockwise CCW as viewed from the input gear 54 side in the disengaged state, the clutch mechanism of the operation unit 5' in the clutch-engaged state operates in the same manner as the clutch mechanism of the operation unit 5. That is, the clutch 6' rotates in the CCW direction, and the cam groove 643 slides against the steel ball 65 in response to the rotation of the cam member 64, moving toward the first clutch receiver 56A side, resulting in the first engaged state as shown in FIG. 22. In the first engaged state, as in the clutch mechanism according to the first embodiment, further rotation in the CCW direction of the cam member 64 is restricted by the steel ball 65, so that when the input shaft 55 is further rotated in the CCW direction, the clutch is released, and the rotational driving force of the CCW rotation is transmitted to the first drive shaft 201A via the path indicated by the symbol R1 in the figure. The first drive shaft 201A to which the rotational driving force of the CCW rotation is transmitted rotates the first winding drum 202A in the CCW direction to raise the bottom rail 31.

[0065] In this embodiment, the operation unit 5' transitions between the disengaged state and the first engaged state only. Therefore, as shown in Fig. 21, it is sufficient that the cam groove 643 is formed from the position of the steel ball 65 in the disengaged state to the position of the steel ball 65 in the first engaged state. For this reason, the cam groove 643 according to this embodiment has a shorter circumferential length than the cam groove 643 according to the first embodiment. As a result, the clutch mechanism is in the first engaged state when the steel ball 65 is located at one end of the cam groove 643, and is in the disengaged state when the steel ball 65 is located at the other end of the cam groove 643.

[0066] On the other hand, when the operating cord 51 is pulled a predetermined distance and then released so that the pulley 52 rotates CCW by a predetermined distance, the bottom rail 31 descends under its own weight. The rotational driving force of the CW rotation from the first drive shaft 201A generated by the bottom rail 31 descending under its own weight is transmitted to the first clutch receiver 56A through the path indicated by the reference symbol R3 as in the first embodiment, as shown in FIG. 23. As a result, the clutch 6' is pushed out in the direction of separation as in the first embodiment, and the first engagement state is released, so that the rotational driving force of the first drive shaft 201A is not transmitted to the clutch 6' and is not transmitted to the input shaft 55 or the pulley 52. ​​When the first engagement state is released, it is preferable that the steel ball 65 is positioned at the other end of the cam groove 643 as shown in FIG. 23 and enters a disengaged state.

[0067] In addition, in the first engagement state, when the input shaft 55 is rotated clockwise CW as viewed from the input gear 54 side, the clutch mechanism of the operation unit 5' operates in the same manner as the clutch mechanism of the operation unit 5, and the cam groove 643 slides against the steel ball 65 in response to the rotation of the cam member 64, and the clutch 6' moves toward the input gear 54. When the clutch 6' continues to move toward the input gear 54, the clutch mechanism goes into a disengaged state as shown in FIG.

[0068] In the disengaged state, the steel ball 65 is located at the other end of the cam groove 643 and further rotation of the cam member 64 in the CW direction is restricted by the steel ball 65. Therefore, even if the input shaft 55 is further rotated in the CW direction, the cylindrical member 62, the first and second transmission members 61A, 61B, etc. simply rotate freely relative to the cam member 64 and no rotational driving force is transmitted to the first drive shaft 201A.

[0069] According to the present embodiment described above, even in an opening and closing device 1' with a single pleated screen, it is possible to prevent co-rotation as in the opening and closing device 1 according to the first embodiment. Furthermore, it is possible to reduce the number of parts in the operation unit 5', thereby achieving lower costs and more compact parts.

[0070] In this embodiment, an endless operation cord 51 formed as a ball chain is wound around the pulley 52, and pulling the operation cord rotates the pulley 52 and inputs the rotation to the input shaft 55. However, an operation cord formed as a single string, one end of which is connected to the pulley so as to be able to be wound and unwound, and the other end of which hangs down from the head box 2 to the outside, may be pulled to rotate the pulley in the CCW direction and input the rotation to the input shaft 55. In this case, the pulley is configured to rotate in the opposite CW direction when the operation cord is released, and to return to the original state before the operation cord was pulled.

[0071] Such a pulley may be, for example, one that is axially supported by the housing of the operation unit 5' so as to be relatively rotatable, with one end of a power spring connected thereto and the other end connected to the housing of the operation unit 5'. The power spring constantly applies a biasing force to the pulley in the winding direction in which the operation cord is wound up, and as a result, the pulley rotates in the CCW direction when the operation cord is pulled by the operator and unwound from the pulley. On the other hand, when the pulled operation cord is released, it is wound around the pulley, causing the pulley to rotate in the CW direction.

[0072] When the pulley rotates in the CCW direction, the clutch mechanism shifts from the disengaged state shown in Fig. 21 to the first engaged state shown in Fig. 22, and the rotational drive force of the CCW rotation is transmitted to the first drive shaft 201A via the path indicated by reference symbol R1 in the figure. On the other hand, when the pulley rotates in the CW direction, the clutch mechanism shifts from the first engaged state shown in Fig. 22 to the disengaged state shown in Fig. 21 or Fig. 23, and the rotational drive force of the CW rotation is not transmitted to the first drive shaft 201A. In other words, when the screen 31 is raised by repeatedly pulling and releasing the operation cord, the clutch mechanism repeatedly shifts between the disengaged state and the first engaged state.

[0073] In an opening and closing device equipped with such an operating cord and pulley, when the bottom rail 31 is in a raised state and the operating cord is pulled a predetermined distance and then released, the rotation restriction on the first drive shaft 201A by the first stopper 203A is released, and the bottom rail 31 descends under its own weight. During the descent under its own weight, as shown in Fig. 23, the rotational driving force of the CW rotation from the first drive shaft 201A is transmitted to the first clutch receiver 56A and pushed in the direction in which the clutch 6' separates, and so it goes without saying that it is not transmitted to the pulley.

[0074] The present invention can be implemented in various other forms without departing from the spirit or main features thereof. Therefore, the above-described embodiments are merely illustrative in all respects and should not be interpreted as being limiting. The scope of the present invention is defined by the claims and is not limited to the text of the specification. Furthermore, all modifications, various improvements, substitutions and alterations within the scope of the claims are within the scope of the present invention. [Explanation of symbols]

When the rotation is restricted after a predetermined amount of rotation, the transmission of the rotation of the shaft member is interrupted by the release of the clutch spring, and the shaft member and the transmission member rotate relative to the cam member.
