By the way, in the above-mentioned opening / closing operation device, it is necessary to fix the operation box at a height within reach on the wall surface of the building. Moreover, a space for rotating the handle is required around the operation box. Therefore, when the above-mentioned opening / closing operation device is applied, it is necessary to secure a space for installing the operation box, which may cause a problem that the installation place is greatly restricted.

In view of the above circumstances, the present invention provides an opening / closing operation device and fittings capable of easily opening / closing a shoji screen without being restricted by the installation location even for fittings placed in a high place. The purpose is.

In order to achieve the above object, the fitting opening / closing operation device according to the present invention operates so as to open the obstacle to the frame body when a rotational operation force in the opening direction is applied, and also operates in the closing direction. An opening / closing operation device for operating an opening / closing device that operates so as to close the obstacle to the frame body when a rotation operation force is applied, and is a tubular first cord-like body. A second cord-like body arranged so as to be relatively movable inside the cylinder of the first cord-like body, an output shaft connected to the opening / closing device, the first cord-like body, and the first cord-like body. An opening operation mechanism that is connected to one of the two cords and operates when the connected cord is pulled to rotate the output shaft in the opening direction, and the first cord. A closing operation mechanism that is connected to either one of the shape and the second cord and operates when the connected cord is pulled to rotate the output shaft in the closing direction. It is characterized by being prepared.

According to the present invention, as the opening operation mechanism and the closing operation mechanism for rotating the output shaft, those operated by the pulling operation of the first cord-like body or the second cord-like body are applied, and therefore these opening operations are applied. Only the end of the first cord and the end of the second cord derived from the mechanism and the occlusion operation mechanism need to be arranged at a reachable height. Moreover, since the first cord-like body and the second cord-like body are only pulled along the longitudinal direction, a large space is not required around them. Further, since the first cord-like body and the second cord-like body coaxially arranged are applied, a narrow space for installation is sufficient.

Further, according to the present invention, in the above-mentioned fitting opening / closing operation device, when one of the first cord-like body and the second cord-like body is pulled in one direction from the state of being stopped at the initial position. Return to rotate the input pulley toward the initial position when the tensile operating force applied to either the rotating input pulley and either the first cord-like body or the second cord-like body is removed. Intervening between the member and the input pulley to the output shaft, the operating force is transmitted when the input pulley rotates in one direction, while the operating force is cut when the input pulley rotates in the other direction. It is characterized by having a clutch mechanism portion that is in a state.

According to the present invention, if either one of the first cord-like body and the second cord-like body is pulled to rotate the input pulley in one direction, the output shaft is rotated. Moreover, when the tensile operating force is removed, the input pulley is returned to the initial position by the return member, and one of the first cord-like body and the second cord-like body to be tension-operated accordingly. Will be wound up on the input pulley. When the input pulley rotates in the other direction, the clutch mechanism portion is in the operating force disengaged state, so that the output shaft does not rotate in the opposite direction. Therefore, if the pulling operation force is repeatedly input / removed with a short stroke to either the first cord-like body or the second cord-like body, the output shaft can be operated without performing the tension operation with a large stroke. It is possible to continuously rotate in the same direction, which is advantageous in terms of operability.

Further, in the above-mentioned fitting opening / closing operation device, the present invention accumulates a rotational operation force when either one of the first cord-like body and the second cord-like body is pulled and operated, while the first. It is provided with an operating force accumulating unit that releases the rotational operating force accumulated when any one of the cord-like body 1 and the second cord-like body is pulled to rotate the output shaft. It is a feature.

According to the present invention, after pulling one of the first cord and the second cord, the other of the first cord and the second cord is pulled.

The gear and the control gear, the accumulator member that elastically deforms when the accumulator gear rotates in one direction, and the accumulator gear mesh with the accumulator gear, and the control gear is rotated in one direction by the rotation of the input pulley in one direction. When the output shaft is rotated, the output shaft is rotated in one direction, and the transmission gear that rotates the storage gear in one direction, and the device main body are in an engaged state and a non-engaged state with respect to the control gear. The control gear is movably arranged so as to allow rotation of the control gear in one direction when engaged with the control gear, restrict rotation of the control gear in the other direction, and control the control gear. The control gear is provided with an engaging member that allows rotation of the control gear in the other direction when the control gear is disengaged from the above, and either one of the first cord-like body and the second cord-like body is provided. When the engaging member is maintained in a state of being engaged with the control gear when the pulling operation is performed, and when either one of the first cord-shaped body and the second cord-shaped body is pulled-operated. The engaging member moves to a position where it is not engaged with the control gear.

According to the present invention, when either one of the first cord-like body and the second cord-like body is pulled, the engaging member is maintained in a state of being engaged with the control gear, and the other direction of the control gear. When the control gear rotates in one direction via the input pulley, the output shaft rotates in one direction and the storage gear rotates in one direction, causing the storage member to elastically deform. Maintain the state. From this state, when either the first cord-like body or the second cord-like body is pulled, the engaging member moves to a position where it is not engaged with the control gear. As a result, the rotation of the control gear is allowed, and the storage gear can also rotate. Therefore, when the storage member returns to the original state, the storage gear rotates in the other direction, and the output shaft is passed through the transmission gear. Will rotate in the other direction. Therefore, when changing the open / closed state of the shoji from the open / closed state of the shoji, it is not necessary to pull out either the first cord-like body or the second cord-like body with a large stroke, and the operation is easy. It becomes possible to do it.

Further, the fitting according to the present invention operates so as to open the shoji to the frame when a rotation operation force in the opening direction is applied, and when a rotation operation force in the closing direction is applied, the fitting is described above. A switchgear that operates so as to close the shoji to the frame is provided, and the output shaft of the above-mentioned opening / closing operation device is connected to the opening / closing device.

According to the present invention, as the opening operation mechanism and the closing operation mechanism for rotating the output shaft, those operated by the pulling operation of the first cord-like body or the second cord-like body are applied, and therefore these opening operations are applied. Only the end of the first cord and the end of the second cord derived from the mechanism and the occlusion operation mechanism need to be arranged at a reachable height. Moreover, since the first cord-like body and the second cord-like body are only pulled along the longitudinal direction, a large space is not required around them. Further, since the first cord-like body and the second cord-like body coaxially arranged are applied, the space is also very limited.

It is done. The shoji 20 is configured by attaching an upper stile 22, a lower stile 23, and left and right vertical stiles 24 to the four circumferences of a face material 21 such as glass. Both ends of the upper stile 22 are slidable up and down with respect to the left and right vertical frames 13, and are rotatably supported around the horizontal axis along the longitudinal direction of the upper stile 22. When the upper stile 22 is arranged above the vertical frame 13, the shoji 20 is closed to the frame 10 with the four stiles 22, 23, and 24 in contact with the frame 10, respectively. On the other hand, when the shoji 20 is rotated so that the lower stile 23 protrudes to the outside of the room around the horizontal axis along the longitudinal direction of the upper stile 22, and the upper stile 22 is slid downward, the frame is used. The shoji 20 can be opened to the body 10. The shoji 20 is rotated around the horizontal axis along the longitudinal direction of the upper stile 22 so that the lower stile 23 moves toward the room from the open state with respect to the frame body 10, and the upper stile 22 is moved upward. If it is slid, the shoji 20 can be returned to the closed state with respect to the frame body 10 again. The lower frame 12 of the frame body 10 is provided with an operator unit (switchgear) 30 so as to project toward the indoor side, and is provided with an attachment plate 40.

As shown in FIG. 3, the operator unit 30 has an operator shaft 32 rotatably arranged around a central axis with respect to a unit case 31. The operator unit 30 is supported on the surface of the lower frame 12 facing the room via the unit case 31 in a state where the operator shaft 32 is in an obliquely upward posture toward the room side. The operator shaft 32 moves an output lever (not shown) when it is rotated with respect to the unit case 31, and a link mechanism (shown) called a friction stay provided between the lower frame 12 and the lower stile 23. It is the one that activates. The link mechanism (not shown) is configured by connecting a plurality of links, and the lower frame 12 and the lower frame 23 expand and contract between the lower frame 12 and the lower frame 23 when the output lever moves. It connects the spaces to each other. In the present embodiment, when viewed from the indoor side, when the operator shaft 32 rotates counterclockwise, the shoji 20 opens with respect to the frame body 10, while the operator shaft 32 rotates clockwise. An operator unit 30 and a link mechanism (not shown) are configured so that the shoji 20 is closed to the frame 10.

The attachment plate 40 protrudes from the lower frame 12 toward the indoor side, and supports the opening / closing operation device 50 in a portion extending beyond the wall surface W in the room. The opening / closing operation device 50 operates a link mechanism (not shown) by transmitting an operating force to the operator unit 30 to enable opening / closing of the shoji 20. In the present embodiment, as shown in FIGS. 3 and 4, an input pulley 52, an input gear 53, a control gear 54, a first reduction gear 55, a second reduction gear 56, a transmission gear 57, and an input pulley 52, an input gear 53, a control gear 54, and a transmission gear 57 are inside the apparatus main body 51. The storage gear 58 is provided to form the opening / closing operation device 50. Hereinafter, the components of the opening / closing operation device 50 will be described, and the feature portions of the present invention will be described in detail. For the sake of convenience, the components of the opening / closing operation device 50 will be described in the posture of being attached to the attachment plate 40.

The apparatus main body 51 is configured to include a first case 51B on one side of the reference plate 51A and a second case 51C on the other side of the reference plate 51A. The second case 51C is composed of an upper case portion 51Ca and a lower case portion 51Cb that can be divided into upper and lower cases. As shown in FIGS. 4 and 5, the first case 51B is provided with a first support shaft portion 59 extending along the depth direction of the fitting, and the second case 51C has a lower case portion 51Cb. A second support shaft portion 60 extending along the vertical direction is provided. Among the above-mentioned components, the input pulley 52, the input gear 53, the control gear 54, the first reduction gear 55, and the second reduction gear 56 are provided in the accommodation space AB formed between the reference plate 51A and the first case 51B. The transmission gear 57 and the storage gear 58 are arranged in the accommodation space AC configured between the reference plate 51A and the second case 51C.

The input pulley 52 is a disk-shaped member having a central hole 52a. The input pulley 52 is arranged in the first support shaft portion 59 of the first case 51B via the center hole 52a, and the movement of the first support shaft portion 59 along the axial direction is restricted. It is rotatable around the axis of the first support shaft portion 59. Two meshing holes 52b are provided on the end surface of the input pulley 52 facing the outside of the room. The meshing hole 52b is an arcuate notch provided on the same circumference centered on the first support shaft portion 59, and is formed at a position displaced by 180 ° in the circumferential direction from each other.

A return spring (return member) 61 is provided between the input pulley 52 and the first case 51B. The return spring 61 functions to maintain the input pulley 52 in the initial position in a state where no external force is applied to the input pulley 52. On the other hand, when an external force is applied to the input pulley 52 so as to rotate counterclockwise when viewed from the indoor side, the state is elastically deformed. When the external force applied to the input pulley 52 is removed while the return spring 61 is elastically deformed, the input pulley 52 rotates clockwise when viewed from the indoor side due to the elastic restoring force of the return spring 61, as described above. It will return to the initial position.

As shown in FIG. 6, the input gear 53 and the control gear 54 are external tooth gears having substantially the same outer diameter, and the first support of the first case 51B is provided with the input gear 53 facing the input pulley 52, respectively. It is rotatably arranged on the shaft portion 59. The input gear 53 is movable along the axis of the first support shaft portion 59, and the control gear 54 is restricted from moving along the axis of the first support shaft portion 59. The input gear 53 and the control gear 54 are provided with a plurality of engaging protrusions 53a and 54a on the same circumference as each other, and a release spring 62 is provided between them. The engaging protrusions 53a and 54a and the release spring 62 are for forming a clutch mechanism portion of the opening / closing operation device 50, respectively. In the present embodiment, one of the surfaces facing each other is the vertical faces 53x and 54x along the axis of the first support shaft portion 59, respectively, and the other surfaces facing each other are the axes of the first support shaft portion 59, respectively. The engaging projections 53a and 54a are configured so as to have inclined surfaces 53y and 54y that are inclined with respect to the inclined surface. In the engaging protrusions 53a and 54a having the above configuration, when the input gear 53 is rotated counterclockwise when viewed from the indoor side, the engaging protrusions 53a of the input gear 53 and the engaging protrusions 54a of the control gear 54 are mutually aligned. Since the contact is made via the vertical faces 53x and 54x, the rotation of the input gear 53 is transmitted to the control gear 54, and the control gear 54 rotates in the same direction. On the other hand, when the input gear 53 rotates clockwise when viewed from the indoor side, the engaging projection 53a of the input gear 53 and the engaging projection 54a of the control gear 54 mutually pass through the inclined surfaces 53y and 54y. As a result of the contact, they are separated from each other, and the control gear 54 is maintained in the stopped state. The release spring 62 separates the input gear 53 from the control gear 54 along the axial direction so that the engagement projections 53a and 54a do not come into contact with each other even when the input gear 53 and the control gear 54 rotate relative to each other. It functions to press the input gear 53 against the input pulley 52.

As shown in FIGS. 3 and 4, two input protrusions 53b projecting toward the end surface of the input pulley 52 are provided at a portion of the input gear 53 facing the input pulley 52. The input protrusion 53b is inserted into the meshing hole 52b of the input pulley 52, and has a cam surface 53c at each base end portion. The cam surface 53c is for forming a clutch mechanism portion of the opening / closing operation device 50, similarly to the engagement protrusions 53a and 54a described above. In the present embodiment, when the input pulley 52 rotates counterclockwise when viewed from the indoor side, the input gear 53 is separated and moved with respect to the input pulley 52, and the input gear 53 resists the pressing force of the release spring 62. The cam surface 53c is provided so that the engaging projection 53a of the above and the engaging projection 54a of the control gear 54 can be engaged with each other. Reference numeral 63 in the drawing is a damper gear provided on the load shaft 64a of the rotary damper 64 for the input gear. The damper gear 63 meshes with the input gear 53 at an appropriate position.

The first reduction gear 55 and the second reduction gear 56 are external tooth gears that are rotatable and meshed with each other between the control gear 54 and the reference plate 51A. The first reduction gear 55 is rotatably arranged on the first support shaft portion 59 of the first case 51B. Although not explicitly shown in the figure, meshing teeth 55a and 54b that are always meshed with each other are provided on the end faces of the first reduction gear 55 and the control gear 54 facing each other. The meshing teeth 55a and 54b are for rotating the control gear 54 and the first reduction gear 55 in an integral manner at all times. The second reduction gear 56 is mounted on one end of an output shaft 65 rotatably arranged so as to penetrate the reference plate 51A so as not to rotate relative to each other.

The transmission gear 57 is a bevel gear fixed to the other end of the output shaft 65, and is arranged so that the small diameter end portion is on the outdoor side. A flexible shaft 66 is connected to an end portion of the output shaft 65 located on the outdoor side.

The storage gear 58 is a ring-shaped bevel gear that meshes with the transmission gear 57, and is rotatably arranged on the second support shaft portion 60. A spring for storage (power storage member) 67 is provided between the power storage gear 58 and the second case 51C. The power spring 67 is in a state of being elastically deformed when the transmission gear 57 is rotated clockwise when viewed from the indoor side and the power storage gear 58 is rotated clockwise when viewed from above. When the external force applied to the transmission gear 57 is removed while the power spring 67 is elastically deformed, the power storage gear 58 rotates counterclockwise when viewed from above due to the elastic restoring force of the power spring 67. As a result, the transmission gear 57 rotates counterclockwise when viewed from the indoor side. Reference numeral 68 in the figure is a rotary damper for the storage gear that gives a load to the rotation of the storage gear 58.

Further, in the opening / closing operation device 50, a slide member 70 is slidably arranged along the vertical direction in the accommodation space AB between the reference plate 51A and the first case 51B. The slide member 70 is provided with a return spring 71 between the slide member 70 and the first case 51B, and an engaging member 72 is provided at a portion facing the outer periphery of the control gear 54. The return spring 71 is a pressing spring that urges the slide member 70 upward with respect to the first case 51B. When no external force is applied to the slide member 70, the slide member 70 is arranged at the uppermost engaging position with respect to the first case 51B by the return spring 71. If a downward external force is applied against the pressing force of the return spring 71, the slide member 70 can be moved downward with respect to the first case 51B. If the external force applied to the slide member 70 is removed, the slide member 70 will return to the engaged position again due to the elastic restoring force of the return spring 71. The engaging member 72 has a shaft-shaped portion 72a at the base end portion, and is rotatably arranged on the slide member 70 with the tip facing the outer periphery of the control gear 54. A torsion spring 73 is provided between the engaging member 72 and the slide member 70. The torsion spring 73 urges the tip of the engaging member 72 so as to be close to the outer peripheral surface of the control gear 54. When the slide member 70 is arranged at the engaging position, the engaging member 72 is maintained in a state in which the tip thereof meshes with the control gear 54 by the torsion spring 73. When viewed from the indoor side, the control gear 54 in which the engaging member 72 is engaged is allowed to rotate counterclockwise, but is prevented from rotating clockwise. When the slide member 70 moves downward with respect to the first case 51B, the meshing state between the engaging member 72 and the control gear 54 is released, and the control gear 54 is allowed to rotate in both directions.

Further, in the opening / closing operation device 50, as shown in FIGS. 4, 5, and 7, an operation cable 80 is attached to the first case 51B. The operation cable 80 has a central cable portion (second cord-like body) 82 arranged inside the cylinder of the outer peripheral cable portion (first cord-like body) 81 having a cylindrical shape, and the outer circumference of the outer peripheral cable portion 81. Is covered with a cylindrical outer skin 83, and the outer peripheral cable portion 81 and the central cable portion 82 can be individually moved with respect to the outer skin 83. In particular, in the present embodiment, flexible outer skin 83, outer peripheral cable portion 81, and central cable portion 82 are applied, and the outer peripheral cable portion with respect to the outer skin 83 even when the whole is curved. It is possible to move the 81 and the central cable portion 82. As is clear from the figure, a flange portion 83a having a large diameter is provided at the tip portion of the outer skin 83. A grip 84 having a central hole 84a is attached to the base end portion of the outer peripheral cable portion 81, and a sphere 85 for gripping is attached to the base end portion of the central cable portion 82.

The operation cable 80 is attached so as to hang down from the apparatus main body 51 by attaching the flange portion 83a of the outer skin 83 to the inner peripheral groove 51Da of the attachment hole 51D provided between the first case 51B and the reference plate 51A. There is. The mounting hole 51D is provided in a portion that opens downward in the first case 51B and is an extension of a tangent line along the vertical direction with respect to the input pulley 52. The tip of the outer cable portion 81 is connected to the slide member 70, and the tip of the center cable portion 82 is connected to the outer peripheral surface of the input pulley 52. When the input pulley 52 is arranged at the initial position, the central cable portion 82 is wound around the outer peripheral surface of the input pulley 52 so as to be clockwise when viewed from the indoor side.

As shown in FIGS. 1 and 2, the opening / closing operation device 50 configured as described above has a frame of fittings via an attachment plate 40 in a state where a flexible shaft 66 extending from an output shaft 65 is connected to an operator shaft 32. It is attached to the body 10. The operation cable 80 extended from the device main body 51 may be hung as it is, or the grip 84 and the sphere 85 may be fixed at arbitrary positions by appropriately laying the cable 80 on the wall surface W of the building via the outer skin 83. You may try to do it. In any case, the grip 84 and the sphere 85 may be arranged at a height that allows the operator to operate without moving to a high place.

Now, when the central cable portion 82 of the operation cable 80 is pulled downward through the sphere 85 from the state where the shoji 20 is open to the frame body 10, the central cable portion is operated with respect to the outer skin 83 and the outer peripheral cable portion 81. Only the 82 is pulled out downward, and the input pulley 52 around which the central cable portion 82 winds rotates counterclockwise with respect to the apparatus main body 51 when viewed from the indoor side. When the input pulley 52 rotates, when the end surface of the meshing hole 52b and the cam surface 53c of the input protrusion 53b provided on the input gear 53 come into contact with each other, the cam surface 53c acts on the input gear 52 with respect to the input pulley 52. The 53 moves apart, and the engaging projection 53a of the input gear 53 and the engaging projection 54a of the control gear 54 are in a state of being able to engage with each other against the pressing force of the release spring 62. When the rotation of the input pulley 52 continues from this state, the input protrusion 53b comes into contact with the end surface of the meshing hole 52b, so that the input gear 53 rotates together with the input pulley 52, and as a result, the control gear 54 is counterclockwise when viewed from the indoor side. Rotate around. When the control gear 54 rotates, the output shaft 65 rotates via the first reduction gear 55 and the second reduction gear 56, and the operator shaft 32 of the operator unit 30 rotates clockwise when viewed from the indoor side via the flexible shaft 66. Rotate. As a result, the link mechanism (not shown) provided in the fitting operates sequentially so as to reduce the space between the lower frame 12 and the lower frame 23, and the shoji 20 is closed to the frame body 10.

That is, in the opening / closing operation device 50, the input pulley 52, the input gear 53, the control gear 54, the first reduction gear 55, and the second reduction gear 56 form a closing operation mechanism, and the pulling operation of the central cable portion 82 is performed. Is rotated in the closing direction of the output shaft 65 by the closing operation mechanism, and the shoji 20 can be closed with respect to the frame body 10.

Here, according to the opening / closing operation device 50, if the pulling operation force of the central cable portion 82 is removed, the input pulley 52 is returned to the initial position by the return spring 61, and the center cable portion 82 is returned to the input pulley 52. It is wound back to its original length. Moreover, when the input pulley 52 returns to the initial position, the engagement between the engagement projection 53a of the input gear 53 and the engagement projection 54a of the control gear 54 is released by the pressing force of the release spring 62, so that the input is input. The rotation of the pulley 52 is not transmitted to the control gear 54. In addition, since the engaging member 72 is maintained in a state of being engaged with the control gear 54, counterclockwise rotation of the control gear 54 is permitted when viewed from the indoor side, while clockwise rotation is allowed. It will be in a blocked state. Therefore, as an operation for closing the shoji 20, it is not necessary to pull out the central cable portion 82 with a large stroke until the shoji 20 is fully closed. That is, if the central cable portion 82 is pulled by a predetermined distance, the pulling operation force is removed, the input pulley 52 returns to the initial position, and then the pulling operation is repeatedly performed, the output shaft 65 is continuously closed. It will rotate only in the direction. This not only makes it possible to easily perform an operation when closing the shoji 20, but also eliminates the need to prepare a central cable portion 82 having a long dimension.

Further, during the operation of closing the shoji 20, according to the opening / closing operation device 50, the transmission gear 57 rotates clockwise when viewed from the indoor side, so that the rotation of the storage gear 58 causes the storage spring 67 to be elastic. It becomes a deformed state. Moreover, as described above, since the engaging member 72 is engaged with the control gear 54, the storage gear 58 does not rotate in the opposite direction, and the elastic deformation of the storage spring 67 does not recover. Therefore, the amount of deformation of the power-storing spring 67 gradually increases with the rotation of the transmission gear 57.

On the other hand, when the outer peripheral cable portion 81 of the operation cable 80 is pulled downward through the grip 84 in order to release the shoji 20 from the state where the shoji 20 is blocked with respect to the frame body 10, the outer skin 83 and the central cable portion 82 are subjected to the operation. On the other hand, only the outer peripheral cable portion 81 is pulled out downward. As a result, the slide member 70 moves downward against the pressing force of the return spring 71 with respect to the apparatus main body 51, and the engagement state of the engaging member 72 with the control gear 54 is released. Rotation in both directions is allowed. When the control gear 54 is allowed to rotate clockwise when viewed from the indoor side, the power storage gear 58 stopped via the first reduction gear 55, the second reduction gear 56, and the transmission gear 57 starts from above. As you can see, it can rotate counterclockwise. As a result, the elastic restoring force of the power spring 67 causes the power storage gear 58 to rotate counterclockwise when viewed from above, and the transmission gear 57 and the output shaft 65 to rotate counterclockwise when viewed from the indoor side. Therefore, the operator shaft 32 of the operator unit 30 rotates counterclockwise when viewed from the indoor side via the flexible shaft 66. As a result, the link mechanism (not shown) provided in the fitting operates sequentially so as to expand the space between the lower frame 12 and the lower frame 23, and the shoji 20 is opened to the frame body 10.

That is, in the opening / closing operation device 50, the slide member 70, the engagement member 72, the control gear 54, the first reduction gear 55, the second reduction gear 56, the transmission gear 57, and the power storage gear 58 form an opening operation mechanism. The pulling operation of the outer peripheral cable portion 81 is rotated in the opening direction of the output shaft 65 by the opening operation mechanism, and the shoji 20 can be opened with respect to the frame body 10.

As described above, when the shoji 20 is released, the engagement state between the engaging member 72 and the control gear 54 may be maintained in a disengaged state, and the outer peripheral cable portion 81 may be opened until the shoji 20 is fully opened. There is no need to pull out with a large stroke. This not only makes it possible to easily perform the operation when opening the shoji 20, but also eliminates the need to prepare a long outer peripheral cable portion 81. After the shoji 20 is opened, if the pulling operation force of the outer peripheral cable portion 81 is removed, the slide member 70 moves upward with respect to the apparatus main body 51 due to the pressing force of the return spring 71, and the engaging member 72 is controlled again. It returns to the state of being engaged with the gear 54.

As described above, according to the opening / closing operation device 50, if the sphere 85 of the central cable portion 82 and the grip 84 of the outer peripheral cable portion 81 arranged at a reachable height are pulled and operated, they are arranged at a high place. The shoji 20 of the fitting can be opened and closed, and the opening and closing operation of the shoji 20 can be easily performed. Moreover, the central cable portion 82 and the outer peripheral cable portion 81 are coaxially arranged, and both may be pulled along the longitudinal direction. Therefore, a large installation space is not required in the surroundings, and if there is a small space, the installation is possible, and there is no possibility that the installation location is restricted.

In the above-described embodiment, the shoji 20 is opened and closed with respect to the frame 10 by operating the link mechanism (not shown) via the operator unit 30, but the switchgear is used as an opening / closing device. Is not necessarily limited to that of the embodiment. In this case, the fitting does not necessarily have to be a horizontal sliding window, and can be similarly applied to other fittings such as a vertical sliding window, a protruding window, and a sliding window. Needless to say, in the fittings other than the sliding window, the opening / closing mechanism does not need to be the operator unit 30 shown in the embodiment.

Further, in the above-described embodiment, the outer peripheral cable portion 81 is connected to the slide member 70 of the opening operation mechanism, and the central cable portion 82 is connected to the input pulley 52 of the closing operation mechanism. A portion 81 and a central cable portion 82 may be connected. Similarly, when the obstacle 20 is closed with respect to the frame 10, the storage spring 67 is elastically deformed, and when the elastically deformed storage spring 67 returns to the original state, the storage spring 67 is elastically deformed with respect to the frame 10. Although it is configured to open the obstacle 20, when the storage spring 67 is elastically deformed when the obstacle 20 is opened with respect to the frame body 10, the storage spring 67 returns to the original state. The obstacle 20 may be configured to block the frame 10.

Further, in the above-described embodiment, the mainspring is applied as both the return member and the power storage member, but it is not always necessary to apply the mainspring as long as it is elastically deformed. Further, although the apparatus main body 51 is composed of the reference plate 51A, the first case 51B and the second case 51C, the present invention is not limited to this.
