Description

  The present invention relates to a cord adjuster and a partition device in a partition device such as an accordion curtain or a folding door.

  A partition device such as an accordion curtain or a folding door draws a partition member such as a bellows-like extendable curtain member between wall surfaces or folds it on one wall surface side to appropriately partition an indoor space.

  Such a partition device is configured to suspend and support the partition member using a plurality of runners movable in the hanger rail.

  For example, in an accordion curtain, a curtain material is attached to a framework that expands and contracts in a pantograph shape, and a curtain body is constructed. A movable rod is attached to a support shaft at one end of the framework so as to be relatively rotatable, and a support shaft at the other end. A fixing rod is attached to the frame so as to be relatively rotatable. The fixed rod is fixed to the wall surface, and the curtain body can be expanded and contracted along the hanger rail by moving the movable rod.

  By the way, in such a partition device, a cord may be used for opening and closing the curtain material. For example, such a cord needs to be adjusted in length according to the size of the curtain material and fixed at one end to a moving rod or the like. In general, knotting balls are often formed when the length of a cord is adjusted and fixed. However, in this knotting method, every time the length of the cord is adjusted, the knotting ball is unwound and reconnected, so that the work efficiency at the time of construction and maintenance is not good.

  Therefore, in order to fix the cord to a moving rod or the like at an arbitrary position by a simpler method, a technique of winding and fixing one end of the cord around an attachment member provided on the moving rod or the like is disclosed (for example, Patent Documents). 1 and 2).

  In the technique of Patent Document 1, a cord is inserted into a mounting member (mounting tool) provided inside a moving rod (frame) in an accordion curtain, and then wound around a locking claw provided on the end side of the mounting tool. The length is adjusted and fixed.

  The technique of Patent Document 2 is different from the accordion curtain, but when fixing the lifting / lowering cord to the bottom rail such as an indoor blind, an attachment member (base) that is detachably fixed inside the bottom rail is provided. One end of the lifting / lowering cord is introduced and wound around the base, and the length is adjusted and fixed.

  Incidentally, an accordion door that opens and closes a main body via a predetermined operation string is disclosed as a conventional partition device (see, for example, Patent Document 3).

  In the technique of Patent Document 3, first, the door body is suspended and supported using a plurality of traveling rollers that can move in the traveling rail. On the other hand, a driving pulley is provided at one end portion on the outer side of the traveling rail, and a guide pulley is provided on the other end portion on the outer side of the traveling rail. The open / close wire is tensioned between the drive pulley and the guide pulley, and one end of the open / close wire is locked to one side end of the door body, and the other end is connected to the inside of the main body from the other side end. And connected to the one side end. Therefore, an operation pulley is attached to the end of the spindle of the drive pulley, and the operation string is suspended from the operation pulley, so that the main body can be opened and closed via the operation string.

No. 1-222076 Japanese Patent No. 4423592 Japanese Patent Publication No. 4-74516

  In the techniques of Patent Documents 1 and 2, unlike the general knot ball method, it is possible to fix the cord to a moving rod etc. at an arbitrary position by a simpler method. Work efficiency at has been improved.

  However, in the techniques of Patent Documents 1 and 2, since it is necessary to release the winding around the attachment member when the length of the cord is adjusted again from a state where one end of the cord is fixed, it is troublesome from the viewpoint of workability. There is a problem that needs to be improved.

  In addition, the techniques of Patent Documents 1 and 2 are not suitable for applications in which the cord is bent during maintenance or a plurality of times because the cord can be bent once the one end of the cord is fixed once.

  In addition, as described above, the technique of Patent Document 3 is such that one end of an open / close wire stretched between a drive pulley and a guide pulley respectively arranged at both outer ends of a traveling rail is attached to one side end of the door body. The other end of the door body is connected to the one side end through the inside of the door body, and an operation pulley is attached to the end of the spindle of the drive pulley. It is configured as follows.

  As in the technique of this Patent Document 3, as a partition device such as an accordion curtain, if the partition member is opened and closed via an operation cord, the partition member is opened and closed by grasping the handle. Even if the operator does not move to move the moving rod directly in accordance with the opening and closing of the partition member, the partition member can be opened and closed by operating the operation code at a fixed position, so that the operability is excellent.

  However, in the accordion curtain configured as in the technique of Patent Document 3, for example, a coil spring is arranged on a framework that expands and contracts in a pantograph shape in the curtain body, and the partition member is automatically closed by the biasing force of the coil spring. Such a configuration causes various problems from the viewpoint of operability and quality.

  That is, when the partition member is automatically closed by the accordion curtain configured as in the technique of Patent Document 3, the operator can operate the operation string (operation code) against the urging force of the partition member in the closing direction. Is operated in the opening direction of the partition member, and the operation pulley is rotated to rotate the drive pulley connected by the rotation support shaft of the operation pulley, and the frictional force generated between the drive pulley and the opening / closing wire by a certain tension is generated. Utilizing this, the rotation of the drive pulley is transmitted to the movement of the opening / closing wire, and is moved in the opening direction of the partition member via the guide pulley.

  For this reason, in order to maintain good operability so that a direct feeling of operation can be obtained while the partition member is configured to automatically close, slip occurs between the operation string (operation cord) and the operation pulley. Coil springs, because there is no contrivance, a contrivance to prevent slippage between the drive pulley and the open / close wire, and slipping with the guide pulley is allowed, but the open / close wire needs to be stretched with the constant tension. Many problems arise from the standpoint of devising the balance between the frictional force corresponding to the urging force and the tension in the drive pulley and guide pulley.

  Moreover, even if the configuration for realizing each of the above-described devices is realized, the durability of the operation pulley, the drive pulley, the guide pulley, and the open / close wire related to the frictional force and the tension must be taken into consideration. A device for maintaining the quality is also required.

  Therefore, a new technique is desired that enables the partition member to be opened and closed by operating the operation code at a fixed position, and improves the operability and reliability of the partition device, without depending on the technique as in Patent Document 3.

  In view of the above problems, an object of the present invention is preferably used for opening and closing a partition member in a partition device that supports a partition member suspended and supported by a plurality of runners so as to be movable along a hanger rail.

The members 65 are connected in the vicinity of the apex protruding in a mountain shape in the thickness direction of the material 65, and are arranged at a plurality of locations (see FIG. 2). When the moving rod 7 is operated in the opening direction from the state in which the moving rod 7 is in contact with the mounting frame 5, the frame is folded and the urging force is accumulated in the plurality of coil springs 64. If the operating grip 40 is released in this state, the curtain material 65 is maintained in the open state at the stop position of the moving rod 7 when the clutch operation for preventing the moving state of the traction cord 51 by the cord stopper device 70 functions. The On the other hand, when the operation grip 40 is released, if the clutch operation that allows the movement state of the traction cord 51 by the cord stopper device 70 functions, the moving rod 7 comes into contact with the mounting frame 5 by the urging force of the coil spring 64. It moves automatically to the fully closed state.

  A curtain material 65 is attached to the outside of the link piece 60. The curtain material 65 is a flat cloth-like member or a skin-like member. The curtain material 65 covers the telescopic mechanism, the traction cord 51, and the like so that they cannot be seen from the outside.

  The bracket 15 is a member for positioning and fixing the hanger rail 2 to the mounting surface. The bracket 15 has a fixing portion for fixing to the mounting surface and a fitting portion for integrating with the hanger rail 2 by turning fitting with the central portion of the main body of the bracket 15 as a turning fulcrum. This fixing portion has a shape that is bent and formed so as to have a gap through which a predetermined cord can be inserted between the mounting surface and the upper surface of the hanger rail 2.

  The cord stopper device 70 allows the moving state of the tow cord 51 in accordance with the moving action of the tow cord 51 passing through the inside thereof (that is, in accordance with the moving action of the operation cord 42 by the operator's operation), or It is a device that performs a so-called clutch operation for switching whether to lock to prevent the movement state, and is provided to improve operability. However, since the cord stopper device 70 is not directly related to the cord adjuster 13 (the case portion 13a and the lever portion 13b) according to the present invention, it will be briefly described below.

  The cord stopper device 70 is configured to include a slider 71 and a clutch mechanism 72. The slider 71 has a pulley 76 that can rotate in the moving direction of the traction cord 51, and has a function of pressing the pulley 76 against the traction cord 51 by the urging force of the spring 73. The clutch mechanism 72 has a drum 74 that can rotate in the moving direction of the traction cord 51 (as will be described later, the drum 74 has a double drum structure of a rotating drum 74a and a brake drum 74b). The drum 74 has a function of a clutch operation that blocks the movement state of the traction cord 51 with the predetermined movement action of the operation cord 42 or allows the movement state. The drum 74 is disposed on the opposite side of the pulley 76 with respect to the traction cord 51. The clutch mechanism 72 is fixed to the fixed rod 8, and the slider 71 is guided so as to be movable in the left-right direction with respect to the clutch mechanism 72. Therefore, the traction cord 51 inserted between the pulley 76 and the drum 74 is pressed by the urging force of the spring 73.

  The drum has a double drum structure, and a rotating drum 74a is located on the outer side in contact with the traction cord 51, and a brake drum 74b is located on the inner side. The brake drum 74b is supported by the clutch mechanism 72 so as not to rotate. The outer surface of the rotating drum 74a has a highly frictional surface shape, and the inner surface has a highly slidable surface shape. The outer surface of the brake drum 74b also has a highly slidable surface shape. Further, since the pulley 76 also has a highly frictional surface shape, the traction cord 51 is pressed between the pulley 76 and the drum 74 by the urging force of the spring 73, thereby enabling the clutch operation.

  The clutch operation will be described. The clutch ball 75 is disposed between the inner surface of the rotating drum 74a and the outer surface of the brake drum 74b. For this reason, the inner surface of the rotating drum 74a has an axial direction ( That is, a guide groove (not shown) for guiding the movement of the clutch ball 75 is provided in the front-rear direction of the accordion curtain 1. In addition, a guide groove (not shown) for applying the clutch operation is provided on the outer surface of the brake drum 74b.

  The guide groove is formed with a movement groove that does not restrict the movement of the clutch ball 75 and a stop groove that restricts the movement of the clutch ball 75 along the rotation direction of the drum 74, and the clutch is formed between the movement groove and the stop groove. A return groove in which the ball 75 can move is formed.

  Therefore, the clutch ball 75 is guided so as to be movable in the guide groove of the brake drum 74b in a state where it is regulated by the guide groove of the rotary drum 74a.

  In order to explain the operation, when the operation cord 42 is pulled down against the urging force of the coil spring 64 by the operation grip 40, the clutch ball 75 forms a moving groove (a movement of the clutch ball 75) that constitutes a part of the guide groove. The rotation of the rotary drum 74a in the direction in which the traction cord 51 passing through the inside of the cord stopper device 70 moves upward (the opening direction of the curtain member 65) is permitted. Here, if the operation grip 40 is released from the state in which the clutch ball 75 is located in the movement groove, the traction cord 51 moves downward (the curtain material 65 closing direction) by the urging force of the coil spring 64. When the clutch ball 75 starts to move and moves into a stop groove (groove for restricting the movement of the clutch ball 75) constituting a part of the guide groove and engages with an end point in the stop groove, The rotation is blocked and the curtain material 65 is stopped at a desired position.

  Subsequently, the operation cord 42 is slightly pulled down against the urging force of the coil spring 64 by the operation grip 40 from the state where the clutch ball 75 is engaged with the end point and the curtain material 65 is stopped at the desired position. If the operation grip 40 is released after the rotary drum 74a is rotated within a predetermined angle range, the traction cord 51 moves in the downward direction (the closing direction of the curtain member 65) by the urging force of the coil spring 64. Thus, the clutch ball 75 moves to the moving groove, and the clutch ball 75 circulates in the moving groove as the rotating drum 74a rotates, and the curtain material 65 automatically moves in the closing direction.

  When the curtain material 65 is stopped at the desired position, the operation cord 42 is further pulled down against the urging force of the coil spring 64 to rotate the rotating drum 74a by a predetermined angle or more, the clutch ball 75 When the operation grip 40 is released by moving from the stop groove into the moving groove and the rotation of the operation grip 40 in this state, the rotation of the rotation drum 74a by the urging force of the coil spring 64 causes the clutch ball 75 to move into the stop groove. The movement of the curtain material 65 is stopped.

  Further details regarding the clutch ball and the guide groove for realizing such a clutch operation are described in, for example, as a take-up shaft instead of the rotating drum 74a and a lifting groove and a lowering groove instead of the moving groove. Please refer to the contents disclosed in Japanese Patent No. 6-013825 or Japanese Patent No. 3124716.

  The soft closing device 80 decelerates the movement of the moving rod 7 so that the moving rod 7 is not damaged by the fingers or hands of third parties other than the operator when the moving rod 7 moves in the direction of the mounting frame 5. Or it is a buffer device (damper device) which stops. The soft closing device 80 is not an essential component for realizing the function of the accordion curtain 1, and does not have a direct relationship with the cord adjuster 13 (the case portion 13a and the lever portion 13b) according to the present invention. Therefore, further detailed description is omitted.

  The accordion curtain 1 configured in this way is not structured to pull out the curtain body by grasping the handle, but pulled out from the curtain body via the operation cord, so that the operator does not have to move with the movement of the moving rod. For example, the pulling-out operation in a state where the wheelchair user faces directly becomes easy, and the operability is improved.

  Further, in order to directly enable opening and closing of the accordion curtain 1 using the operation cord 42 connected to the operation grip 40, for example, a mechanism for indirectly transmitting the operation by the operation cord 42 to the drive of the moving rod 7 is provided. Compared with the partition device, a direct feeling of operation is generated, so that operability is improved.

  However, the cord stopper device 70 and the like may be damaged if an attempt is made to further pull the moving rod 7 against the holding force that prevents the cord stopper device 70 from moving the cord 51.

  The function that prevents the cord stopper device 70 and the like from being damaged even during such a hand-drawing operation is referred to as a “fail-safe function”. The fail-safe function is provided in the cord adjuster 13 according to the present invention. It is possible.

  Hereinafter, as a representative, the fail-safe function in the cord adjuster 13 of the second embodiment will be described.

  As shown in FIGS. 12 and 13, the cord adjuster 13 having the fail-safe function is a fitting force (ie, fitting force when the fitting receiving portion 306 of the case portion 13a is fitted to the fitting claw portion 309 of the lever portion 13b). The locking force of the cord adjuster 13) is not related to the traction cord 51 when a predetermined tension greater than the traction force required to pull the movable rod 7 during normal operation by the operation grip 40 is applied to the traction cord 51. It has been adjusted to stop.

  Further, since the traction cord 51 is inserted through the cord stopper device 70 that can prevent the movement of the traction cord 51, the predetermined tension is smaller than the holding force that the cord stopper device 70 prevents the movement of the traction cord 51. Have been adjusted so that.

  Further, when the traction cord 51 is locked by the cord adjuster 13 having a fail-safe function, the traction cord 51 is locked in a state where there is a pre-length.

  FIG. 17A is a front sectional view of the lever portion 13b of the cord adjuster 13 of the second embodiment according to the present invention before the cord is locked to the case portion 13a, and FIG. 17B is the second embodiment of the present invention. It is front sectional drawing after the cord latching to the case part 13a regarding the lever part 13b in the cord adjuster 13 of.

  First, as shown in FIG. 17A, the traction cord 51 is inserted into both the case portion 13a and the lever portion 13b, and when adjusting the length of the traction cord 51, the longitudinal direction of the case portion 13a is set. On the other hand, the longitudinal direction of the lever portion 13b is positioned in a substantially vertical direction.

  Next, as shown in FIG. 17 (b), as described above, the lever portion 13b is rotated so that the longitudinal direction of the lever portion 13b is located in a substantially parallel direction with respect to the longitudinal direction of the case portion 13a. Although the outer shape of the lever portion 13b is fixed in a state of being accommodated in the case portion 13a, for example, the traction cord 51 is locked in a state where there is a pre-length d up to the knot ball.

  This pre-length d can be set to an arbitrary length, and this pre-length d corresponds to the movement distance of the moving rod 7 permitted by the fail-safe function, as will be described later. More specific description will be given with reference to FIG. FIG. 18A is an explanatory diagram showing a state when the cord adjuster 13 according to the second embodiment is operated in the closing direction by guidance of the moving rod 7, and FIG. 18B is a cord adjustment according to the second embodiment. It is explanatory drawing which shows the state which cancels | releases locking by the fail safe function in the device 13, FIG.18 (c) is operation to the closing direction by the guide of the moving rod 7 by the fail safe function in the cord regulator 13 of 2nd Embodiment. It is explanatory drawing which shows the state of time.

  First, referring to FIG. 18A, as described above, in the cord adjuster 13 of the second embodiment, the traction cord 51 is locked at two locations (first locking position and second locking position). can do. In this state, it is assumed that the moving rod 7 is further forcibly pulled (Op in the drawing) against the holding force of the traction cord 51 by the cord stopper device 70.

  Then, as shown in FIG. 18B, a tension T acts on the traction cord 51, and the tension T is larger than the traction force (for example, 3 kg weight) required to pull the movable rod 7 during the normal operation by the operation grip 40. When the predetermined value is reached, a force is applied to keep the traction cord 51 bent and locked in two places (first locking position and second locking position) in a straight line, and the case portion 13a and the lever The fitting with the part 13b is released. When the fitting between the case portion 13a and the lever portion 13b is released, although the tension T is weakened, the force for maintaining the traction cord 51 in a straight line continues to work, and the traction cord 51 moves (m in the drawing).

  The tension T (for example, 10 kg weight) when the fitting between the case portion 13a and the lever portion 13b is released is smaller than the holding force (for example, 15 kg weight) of the traction cord 51 by the cord stopper device 70. Since the fitting force (that is, the locking force of the cord adjuster 13) is adjusted, the fitting between the case portion 13a and the lever portion 13b is released before the cord stopper device 70 is damaged. become.

  Then, the movement of the traction cord 51 after the fitting between the case portion 13a and the lever portion 13b is released is secured up to the position of the knotted ball of the traction cord 51, that is, as shown in FIG. Movement by the guide of the moving rod 7 is allowed to the position of the knot ball.

  Here, with reference to FIG. 19, it supplements about the operation | movement regarding the presence or absence of a fail safe function. FIG. 19A is an explanatory diagram showing a state where there is no safety measure by the fail safe function in the cord adjuster 13 of the second embodiment, and FIG. 19B is a fail safe in the cord adjuster 13 of the second embodiment. It is explanatory drawing which shows the state with the safety measure by a function. As shown in FIG. 19, the cord adjuster 13 for the traction cord 51 a is installed on the upper side of the movable rod 7, and the cord adjuster 13 for the traction cord 51 b is installed on the lower side of the movable rod 7.

  As shown in FIG. 19 (a), when the cord adjuster 13 is not provided with a safety measure by the fail-safe function, the moving rod 7 is further forcibly resisted against the holding force of the traction cord 51 by the cord stopper device 70 in various places. When the manual operation (Op1, Op2, Op3 in the drawing) is performed, the cord stopper device 70 and the like may be damaged. Here, 3 of the hand-drawing operation (illustrated Op1) grabbing the upper side of the moving rod 7, the hand-guiding operation grabbing the lower side of the moving rod 7 (Op-illustrated), and the hand-drawing operation (Op3 illustrated) grabbing the center of the moving rod 7 are illustrated. The types will be illustrated and described.

  For example, as shown in FIG. 19B, in the state where the cord adjuster 13 has a safety measure by the fail-safe function, for example, the upper portion of the movable rod 7 is grasped and the holding force of the traction cord 51 by the cord stopper device 70 is resisted. When the moving rod 7 is further forcibly operated (Op1 in the drawing), the traction cord 51a is unlocked by the upper cord adjuster 13 and damage to the cord stopper device 70 and the like can be avoided. At this time, in FIG. 19B, the lower cord adjuster 13 shows an example in which the locking of the traction cord 51b is not released.

  Similarly, for example, when the lower portion of the moving rod 7 is grasped and the moving rod 7 is further forcibly operated against the holding force of the tow cord 51 by the cord stopper device 70 (Op2 in the drawing), only the lower cord adjuster 13 is operated. The traction cord 51b is unlocked by this, and damage to the cord stopper device 70 and the like can be avoided. Then, for example, when the moving rod 7 is grasped near the center and the moving rod 7 is further forcibly operated against the holding force of the tow cord 51 by the cord stopper device 70 (Op3 in the figure), both the upper and lower cord adjusters 13 The locking of the traction cords 51a and 51b is released, and damage to the cord stopper device 70 and the like can be avoided.

  In addition, although the example in which the fail-safe function in the code adjuster 13 in each place operates according to the position (in the drawing, Op1, Op2, Op3) of the moving rod 7 has been described, this is to enhance the understanding of the invention. It should be noted that this is merely an example, and only the fact that the fail-safe function of either one or both of the cord adjusters 13 arranged one above the other according to the method of the manual operation of the mobile rod 7 works. Thus, by configuring the cord adjuster 13 to have a fail-safe function, the cord adjuster 13 can be corded even when the moving rod 7 is further forcibly guided against the holding force of the tow cord 51 by the cord stopper device 70. Damage to the stopper device 70 and the like can be avoided.

  Further, the cord adjuster 13 may return the locking of the traction cord 51 from the state where the traction cord 51 is unlocked by applying the tension T to the traction cord 51 again in FIG. Just do as described. At this time, the cord adjuster 13 is housed inside the movable rod 7, but the cushion material 7 a attached to the front surface of the movable rod 7 is configured to be detachable, so that the tow cord 51 can be easily attached. Can be restored.

  In the above description, the code adjuster 13 according to the second embodiment has been described as an example. However, the code adjuster 13 according to the first embodiment or a modification thereof is similarly configured to have a fail-safe function. can do.

  In the above description, the distance from the traction cord 51 to the knot ball is described as an example with respect to the pre-length d, but the knot ball may not be formed. Further, the traction cord 51 may be loosened or removed from the cord adjuster 13. Even in such a case, the locking of the traction cord 51 can be easily restored as described above. However, considering the ease of return, it is desirable to provide a sufficiently long pre-length d or form a knot so that the traction cord 51 does not come off the cord adjuster 13.

  In the above description, the traction cord 51 can be selected to be locked or unlocked by the rotation of the lever portion 13b that is rotatably attached to the case portion 13a at the rotation fulcrum. The example in which the cord adjuster 13 is provided with a fail-safe function has been described. However, the cord adjuster 13 of any form configured to be able to select locking or non-locking of a predetermined code is fail-safe. It can be configured to have a function. In particular, the movable rod 7 that fixes the partition member can be pulled by the predetermined cord, and the predetermined tension larger than the traction force required to pull the movable rod 7 is applied to the predetermined cord. What is necessary is just to be comprised so that a code | cord | chord will be non-locking. Such a cord adjuster can generally improve the operability and reliability of the partition device.

  In the above explanation, the example in which the fail-safe function of the cord adjuster 13 works when the moving rod 7 is further forcibly operated against the holding force of the tow cord 51 by the cord stopper device 70 has been described. Even when the traction cord 51 is unlocked by the cord stopper device 70, the cord adjuster 13 can be pulled even when the operation grip 40 is pulled even though the partition member (curtain material 65) is fully opened. Fail-safe function is working.

(Operation grip)
Next, from the viewpoint of improving the operability and reliability of the partition device, an example of the operation grip 40 according to the present invention will be described. 20A and 20B are perspective views of the first grip member 40a and the second grip member 40b constituting the operation grip 40 in the partition device according to the embodiment of the present invention (for example, the accordion curtain 1 described above), respectively. FIG. 21 (a), (b), (c), and (d) are configuration diagrams of the first grip member 40a constituting the operation grip 40, and a front view, a top view, and a side view of the first grip member 40a, respectively. The figure and the bottom view are shown. 22A, 22B, 22C, and 22D are configuration diagrams of the second grip member 40b that constitutes the operation grip 40, and are a front view and a top view of the second grip member 40b, respectively. , A side view, and a bottom view.

  The operation grip 40 includes a first grip member 40a and a second grip member 40b that can be locked with the operation cord 42 interposed therebetween. The first grip member 40a and the second grip member 40b are each provided with a fitting portion 401a and a fitting receiving portion 401b at a plurality of locations so that they can be fitted and detached from each other. In addition, the first grip member 40a and the second grip member 40b are capable of penetrating the operation cord 42 in the longitudinal direction by insertion holes 402a and 402b formed in a state of being fitted to each other. The first grip member 40a and the second grip member 40b have symmetrical shapes in the vertical and horizontal directions, respectively.

  In particular, the first grip member 40a and the second grip member 40b can be locked with the knotting balls 42a by the cord locking portions 403a and 403b formed in a state where the first grip member 40a and the second grip member 40b are fitted to each other. ing. For example, FIGS. 23A and 23B show a first installation mode of the operation grip 40. Referring to FIG. 23A, even after the operation cord 42 is pinched and locked by the operation grip 40 at the position of the initial height, the adjustment height (40 ′ in the drawing) is changed by changing the pinching position of the operation cord 42. ) And can be adjusted. More specifically, as shown in FIG. 23 (b), the first grip member 40 a and the second grip member 40 b are formed in a state of being fitted to each other so that the height can be easily adjusted. With the stoppers 403a and 403b, the sandwiched operation cord 42 can be locked with a knot 42a. Further, the pre-length portion 42b of the operation cord 42 can be accommodated by the spaces 404a and 404b formed in a state where the first grip member 40a and the second grip member 40b are fitted to each other. Accordingly, the height can be easily adjusted even after the operation cord 42 is sandwiched and locked.

  Moreover, the 2nd installation aspect of the operation grip 40 is shown to FIG. 24 (a), (b), respectively. This embodiment is an example in which two operation grips 40 shown in FIGS. 20 to 22 are attached to the operation cord 42 as a first operation grip 40-1 and a second operation grip 40-2. The first operation grip 40-1 is configured to be locked while penetrating the operation cord 42, and the second operation grip 40-2 is configured to receive and lock the pre-length portion 42b of the operation cord 42. ing.

  For example, as shown in FIG. 24A, the first operation grip 40-1 is installed at a first height that does not hit the operation unit 6 when the partition member (curtain material 65) is fully closed. The 2-operation grip 40-2 is installed at a second height that can be gripped at a low position such as a wheelchair. The first grip member 40a and the second grip member 40b can pass through the operation cord 42 in the longitudinal direction by insertion holes 402a and 402b formed in a state of being fitted to each other, and the cord locking portions 403a and 403b Since the sandwiched operation cord 42 can be locked by the knot ball 42a, the first operation grip 40-1 can be installed so as to be adjustable as shown in FIG. In addition, since the pre-length portion 42b of the operation cord 42 can be accommodated by the spaces 404a and 404b, the second operation grip 40-2 is installed so as to be adjustable at an arbitrary position below the first operation grip 40-1. Can do.

  In this way, the operation grip 40 is locked to the operation cord 42 in a non-contact manner with the operation unit 6 at the first height position in the vicinity of the operation unit 6 in the fully closed state of the partition member (curtain material 65). The first operation grip 40-1 and the second operation grip 40-2 locked to the operation cord 42 at the second height position below the first operation grip 40-1. Can do. Thereby, the operativity of a partition apparatus can be improved.

  By using such an operation grip 40, it becomes possible to improve the operability and reliability of the partition device.

  In this example, the outer shape of the operation grip 40, the locking means of the knot 42a, or the fitting portion 401a and the fitting provided so that the first grip member 40a and the second grip member 40b can be fitted and detached from each other. The accepting unit 401b and the like have been described by taking a specific form as an example, but it is needless to say that the receiving unit 401b is not limited to the example described above.

  According to the present invention, the cord length can be easily adjusted and locked for any cord used in the partition device, or the operability and reliability of the partition device can be improved. It is useful for applications that require thickness adjustment and fixing, particularly for partition devices.
