Description

  The present invention relates to a partition device such as an accordion curtain or a folding door, and a cord slack prevention device.

  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 curtain material 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, as such a partition device, an accordion door that opens and closes a main body via a predetermined operation string is disclosed (for example, see Patent Document 1).

  In the technique of Patent Literature 1, first, the door body is suspended and supported using a plurality of traveling rollers that are movable 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.

Japanese Patent Publication No. 4-74516

  As described above, in the technique of Patent Document 1, 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 locked to one side end of a door body. The other end of the door main body is connected to the one side end through the inside of the main body, and an operation pulley for suspending the operation string is attached to the end of the spindle of the drive pulley. It is composed.

  As a partitioning device such as an accordion curtain, as in the technique of Patent Document 1, if the partition member is opened and closed via an operation cord, the partition member is opened and closed by grasping a 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 technique of Patent Document 1, when an operator performs an opening / closing operation, an indirect mechanism for transmitting and converting rotation of an operation pulley that suspends an operation string into movement of an opening / closing wire accompanying rotation of a drive pulley. Therefore, there is a problem that a direct feeling of operation cannot be obtained and should be improved from the viewpoint of operability.

  More specifically, in order to maintain good operability so that a direct feeling of operation can be obtained with an accordion curtain configured as in the technique of Patent Document 1, an operation string (operation code) and an operation pulley are used. It is necessary to devise such that no slip occurs between them, and to prevent slip between the drive pulley and the open / close wire.

  Further, in the accordion curtain configured as in the technique of Patent Document 1, the operator needs to operate the operation cord in both the opening direction and the closing direction of the partition member, and the convenience related to the operation is improved. There is room for.

  Regarding the improvement of convenience regarding this operation, an accordion curtain configured as in the technique of Patent Document 1, for example, a coil spring is arranged on a pantograph-like frame in the curtain body, and the biasing force of this coil spring If the partition member is configured to automatically close, various problems occur from the viewpoint of operability and quality.

  That is, when the accordion curtain configured as in the technique of Patent Document 1 is configured to automatically close the partition member, the operator can operate the operation string (operation code) against the urging force in the closing direction of the partition member. 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.

  Furthermore, regarding the operation of the operator, not only when the operator operates the operation cord in the opening direction of the partition member against the urging force of the partition member in the closing direction, but also the operator directly opens the partition member. It is excellent in operability to take into account even when operating. However, when the operator directly operates the partition member in the opening direction against the urging force of the partition member in the closing direction, the mechanism that assumes only the operation in the opening direction of the partition member by the operation code is used to open and close the partition member. Since the tension of the various cords used for the loss may occur and the slack may occur, there is a concern about defects caused by this.

  Therefore, with respect to the partition member suspended and supported by a plurality of runners moving in the hanger rail, good operability and quality are maintained in the partition device such as an accordion curtain that can be operated to open and close the partition member by the operation cord. A mechanism for this is desired.

  In view of the above-described problems, an object of the present invention is to provide a partition device and a cord slack prevention device in which driving of a partition member is facilitated by a predetermined cord.

  The partition device and the cord slack prevention device of the present invention are devices in which the partition member is smoothly driven by a predetermined cord. In particular, the cord slack prevention device of the present invention urges the partition member in the closing direction by a predetermined urging mechanism (coil spring in the example of an embodiment described later), and can open and close the partition member by an operation cord. It is suitable to apply to a partition device such as an accordion curtain.

  That is, the partition device of the present invention is a partition device that facilitates the driving of the partition member by a predetermined cord, and is a leading movable body (an example of an embodiment described later) provided on the partition member that is suspended and supported on the hanger rail. Then, a transfer operation means (to be described later) that makes the movable body movable by using the moving rod 7 and the leading runner 4) and the first code (in the example of the embodiment described later, the operation code 42 or the traction cord 51). In the example of the embodiment, a cord equalizer 9) that is transported through operation of the operation unit 6 and the operation grip 40 is provided, and is linked between the transport operation means and the moving body in conjunction with the transport operation means. A moving second cord is connected.

  Further, in the partition device of the present invention, a predetermined urging mechanism for urging the partition member in the closing direction is provided in the partition device, and the movement is performed against the urging force of the predetermined urging mechanism. When the body moves, the first cord and the second cord are configured to move in conjunction with each other.

  In the partition device of the present invention, the second cord includes a tension member that generates tension so as to prevent the slack of the second cord as a part of the second cord.

  Furthermore, the cord slack preventing device of the present invention is a cord slack preventing device for facilitating the driving of the partition member in the partition device, and is a hanger rail that is transported using the first cord by the transport operating means. A second cord is connected between the transfer operation means and the movable body so as to prevent the first cord from slackening with the movement of the leading movable body provided on the partition member that is suspended and supported on the partition member. It is characterized by.

  Further, in the cord slack preventing device of the present invention, the second cord has a tension member that generates a tension so as to prevent its own slack as a part of the second cord.

  According to the present invention, not only the operation by the operation code, but also when the opening / closing operation of the partition member can be performed even when the opening / closing operation is performed by the moving rod, the various codes that are circulated include the operation code directly. It is configured to work together. For this reason, all the cords are allowed to slide with respect to the pulley except where the cords can be intentionally prevented from moving, and the cords such as the traction cords are loosened in any of the opening / closing operations of the operation cord and the moving rod. Therefore, problems such as durability and opening / closing failure can be suppressed, and good operability and quality can be maintained.

  The moving rod 7 is a frame-like member that extends in the vertical direction, and has a cushion material 7 a on the right end surface that abuts the mounting frame 5 of the moving rod 7. The movable rod 7 has a substantially U shape when viewed from above so as to cover one end of the curtain body 14. This prevents the inside of the moving rod 7 from being seen from the outside and prevents the operator's fingers and hands from being damaged. Since the leading runner 4 is fixed on the upper end side of the moving rod 7, when the moving rod 7 moves along the hanger rail 2, the curtain body 14 moves together and opens and closes the curtain member 65. Is done.

  The fixed rod 8 is provided at the left end portion of the accordion curtain 1. The fixing rod 8 is fixed to the left wall surface and is provided so as not to move. The right end surface of the fixing rod 8 has a substantially U shape when viewed from above so as to cover one end of the curtain body 14.

  The code equalizer 9 includes a first connecting portion for attaching one end of the operation cord 42 and one end of the slack prevention cord 26, and each of the two traction cords 51a and 51b (collectively referred to as “traction cord 51”). A second connecting portion for attaching one end. The code equalizer 9 has a size that allows the inner part of the bracket 15 to be inserted, and is provided so as to be movable in the longitudinal direction at the upper part of the hanger rail 2 in accordance with the operation of the operation code 42.

  The turning pulley unit 10 is fixed to the upper end portion of the fixed rod 8. The turning pulley unit 10 includes a pulley 52 inside. After the two traction cords 51a and 51b attached to the second connecting portion provided at one end portion of the cord equalizer 9 turn downward through the pulley 52 and pass through the cord stopper device 70, the traction cord 51a is It turns from the left end to the right end substantially parallel to the longitudinal direction of the hanger rail 2 via the pulley unit 11, and the traction cord 51b from the left end substantially parallel to the longitudinal direction of the hanger rail 2 via the pulley unit 12. Turn towards the right edge. Thereafter, the tow cord 51a is locked by the cord adjuster 13 fixed to the moving rod 7. Similarly, the tow cord 51b is locked by a cord adjuster (not shown) fixed to the movable rod 7. The turning pulley unit 10 may be provided at the left end portion of the hanger rail 2.

  The pulley unit 11 turns the traction cord 51a that goes downward through the turning pulley unit 10 from the left end to the right end substantially parallel to the longitudinal direction of the hanger rail 2. Thereafter, the tow cord 51a is locked by the cord adjuster 13 fixed to the moving rod 7.

  The pulley unit 12 turns the traction cord 51b that goes downward through the turning pulley unit 10 from the left end to the right end substantially parallel to the longitudinal direction of the hanger rail 2. Thereafter, the traction cord 51b is locked by a cord adjuster (not shown) fixed to the movable rod 7.

  The cord adjuster 13 is fixed to the movable rod 7, and when the curtain member 65 is in a fully closed state, the route of the tow cord 51a with respect to the pulley unit 11 is substantially parallel to the longitudinal direction of the hanger rail 2 so that the tow cord 51a Adjust and lock the length. Further, a cord adjuster (not shown) similar to the cord adjuster 13 is fixed to the movable rod 7 so as to similarly lock the traction cord 51b.

  The operation cord 42 is a string-like member, and an end on one end side thereof is attached to the inside of the operation grip 40. On the other hand, the slack prevention cord 26 and the traction cords 51 a and 51 b are provided with a smaller diameter than the operation cord 42. That is, it is not necessary for the operator to operate the slack prevention cord 26 and the traction cords 51a and 51b, but the operation cord 42 is related to the operation of the operator, and thus has a large diameter. Further, the traction cords 51a and 51b pass through the cord stopper device 70 fixed to the fixed rod 8 via the pulley 52 in the turning pulley unit 10 fixed to the upper end portion of the fixed rod 8, and are directed downward. The diameters of the cords 51a and 51b are smaller than the diameter of the operation cord 42.

  Here, the route of the operation code 42, the traction codes 51a and 51b, and the slack prevention code 26 will be described again. When proceeding along the operation cord 42 from the operation grip 40 side, the operation cord 42 passes through the insertion hole of the guide pole 41, and the inside of the bracket 15 along the longitudinal direction of the hanger rail 2 along the longitudinal direction by the operation pulley 43. The direction is turned so as to pass through the portion, and is attached to the first connecting portion of the cord equalizer 9 together with the slack prevention cord 26.

  The two traction cords 51a and 51b attached to the second connecting portion of the cord equalizer 9 are fixed to the fixed rod 8 via the pulley 52 in the turning pulley unit 10 fixed to the upper end portion of the fixed rod 8. Pass the cord stopper device 70. The traction cord 51 a that has passed through the cord stopper device 70 is turned by the pulley unit 11 and is locked by the cord adjuster 13 fixed to the movable rod 7.

The slack prevention cord 26 attached to the first connecting portion of the cord equalizer 9 is directed to the operation unit 6 along the longitudinal direction at the upper part of the hanger rail 2 and moves via the pulley 27 in the operation unit 6. Connected to 框 7.

  As a result, when the operation grip 40 is operated and the operation cord 42 moves to the right in the upper part of the hanger rail 2, the cord equalizer 9 also moves to the right and the tow cord 51 also moves, so the tow cord 51 also moves. At the same time, the moving rod 7 moves in the left direction (the opening direction of the curtain material 65). Along with the movement of the moving rod 7 in the left direction, the slack prevention cord 26 connected to the leading runner 4 fixed to the upper end portion of the moving rod 7 is pulled, so that the cord equalizer 9 is helped to move in the right direction. Come to collaborate.

  The curtain body 14 includes a curtain member 65 and an expansion / contraction mechanism as a framework that expands and contracts in a pantograph shape. One end of the expansion / contraction mechanism is fixed to the moving rod 7 and the other end is fixed to the fixed rod 8. More specifically, as shown in FIGS. 1 and 2, the expansion / contraction mechanism includes a link piece 60 that rotatably connects end portions via a support shaft 61 and a connection shaft 62, and a plurality of coil springs 64. Composed. In addition, the connection shaft 62 is suspended by the suspension member of the runner 3 at intervals of every other, for example. In the example shown in FIG. 1, for example, three sets of expansion / contraction mechanisms are provided in the vertical direction. However, in the accordion curtain 1, any number of expansion / contraction mechanisms may be provided as long as the number is two or more. Good.

  The plurality of coil springs 64 are arranged between the substantially parallel link pieces 60 (front link pieces and rear link pieces) constituting the rhombus portions as the framework so as to urge the curtain material 65 in the closing direction. 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 slack preventing device (the adapter 25 and the slack preventing cord 26) 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.

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.

(Operation of cord slack prevention device)
Next, the operation of the entire apparatus in the presence or absence of the cord slack preventing apparatus (the adapter 25 and the slack preventing cord 26) of the present embodiment will be described in comparison. FIGS. 9A, 9B and 9C are explanatory views showing the operation of the entire apparatus when there is a cord slack preventing apparatus according to an embodiment of the present invention.

  First, an example in which the operation of “when the operation grip 40 is operated” in the cord slack preventing device (the adapter 25 and the slack preventing cord 26) of the present embodiment is applied to the accordion curtain 1 described above will be described. When the operation grip 40 is operated downward from the state before the operation (see FIG. 9A), referring to FIG. 9B, the operation code on the upper part of the hanger rail 2 via the operation pulley 43 is operated. 42 moves to the right. At the same time, the cord equalizer 9 moves to the right and the tow cord 51 also moves. The traction cord 51 (that is, the traction cords 51a and 51b) moves the moving rod 7 in the left direction (opening direction of the curtain member 65) via the pulley 52 of the turning pulley unit 10 and the pulleys of the pulley units 11 and 12. . Then, along with the movement of the moving rod 7 in the left direction, the slack prevention cord 26 connected to the leading runner 4 fixed to the upper end of the moving rod 7 is pulled, so that the movement of the cord equalizer 9 in the right direction is prevented. Help and collaborate.

  In addition, regarding the operation at the time of operation of the moving rod 7 in the cord slack preventing device (the adapter 25 and the slack preventing cord 26) of the present embodiment, from the state before the operation (see FIG. 9A), FIG. Referring to c), when the moving rod 7 is operated in the left direction (the opening direction of the curtain member 65), the leading runner fixed to the upper end of the moving rod 7 as the moving rod 7 moves in the left direction. Since the slack prevention cord 26 connected to 4 is pulled, the cord equalizer 9 moves to the right via the pulley 27. At the same time, the operation cord 42 accompanied by its own weight of the operation grip 40 moves to the right in the upper part of the hanger rail 2. Since the traction cord 51 (that is, the traction cords 51a and 51b) is pulled in conjunction with the movement of the cord equalizer 9 in the right direction, the movement of the movable rod 7 in the left direction is assisted. .

  Next, the operation of the entire device when the cord slack preventing device (the adapter 25 and the slack preventing cord 26) of this embodiment is not provided will be described. FIGS. 10A, 10B, and 10C are explanatory views showing the operation of the entire apparatus when there is no cord slack preventing apparatus according to an embodiment of the present invention.

  First, an operation “when the operation grip 40 is operated” when the cord slack preventing device (the adapter 25 and the slack preventing cord 26) of the present embodiment is not provided will be described. When the operation grip 40 is operated downward from the state before the operation (see FIG. 10A), referring to FIG. 10B, the operation code on the upper part of the hanger rail 2 via the operation pulley 43. 42 moves to the right. At the same time, the cord equalizer 9 moves to the right and the tow cord 51 also moves. The traction cord 51 (that is, the traction cords 51a and 51b) moves the moving rod 7 in the left direction (opening direction of the curtain member 65) via the pulley 52 of the turning pulley unit 10 and the pulleys of the pulley units 11 and 12. . Therefore, even when the cord slack preventing device (the adapter 25 and the slack preventing cord 26) of the present embodiment is not provided, an open / close operation without any problem can be performed “when the operation grip 40 is operated”.

  However, regarding the operation at the time of “operating the moving rod 7” when the cord slack preventing device (the adapter 25 and the slack preventing cord 26) of the present embodiment is not provided, from the state before the operation (see FIG. 10A), Referring to FIG. 10C, even if the moving rod 7 is operated in the left direction (opening direction of the curtain material 65), the code equalizer 9 does not move, and the operation grip 40 does not move. Also does not move. For this reason, the traction cord 51 (that is, the traction cords 51a and 51b) may be loosened inside the curtain body 14, and this looseness may cause problems such as opening and closing failure such as entanglement inside the curtain body 14.

  As described above, in order to summarize the cord slack preventing device (adapter 25 and slack preventing cord 26) of this embodiment, the cord equalizer 9 that connects one end of the traction cord 51 and one end of the operation cord 42 is used, and the slack preventing cord is used. One end of 26 is connected together with one end side of the operation cord 42, and the other end of the slack prevention cord 26 is attached to the adapter 25 integrated with the leading runner 4. The leading runner 4 is fixed to the upper end of the moving rod 7, and the other end of the traction cord 51 is attached to the moving rod 7. By handling the various cords as described above, both ends of the series of cords are attached to the moving rod 7 via the inside of the curtain body 14 and the upper portion of the hanger rail 2. Therefore, a series of these codes move with respect to the movement of the moving rod 7.

  Thus, according to the cord slack prevention device of the present embodiment, the cord equalizer 9 that connects one end of the traction cord 51 and one end of the operation cord 42 and the leading runner 4 fixed to the movable rod 7 are integrated. Since the adapter 25 is connected to the slack prevention cord 26, the curtain body 14 can be opened / closed not only by the operation cord 42 but also when the opening / closing operation is performed by the moving rod 7. Further, since the various cords that are routed are directly linked to the operation cord 42, all the cords except the cord stopper device 70 that can intentionally prevent the movement of the tow cord 51 are pulleys. In addition, since slipping is not allowed and slack does not occur, problems such as durability and opening / closing failure can be suppressed, and good operability and quality can be maintained.

  Further, according to the cord slack preventing device of this embodiment, since the convex portion 258 is formed on the adapter 25 so as to oppose the concave portion 259 of the main body portion 4a, the degree of engagement of the leading runner 4 with respect to the main body portion 4a. The adapter 25 can be integrated with the top runner 4 by a relatively simple procedure, so that the workability is improved, the removal is easy, and the maintainability is also improved.

  Further, according to the cord slack preventing device of the present embodiment, the distal end portion 262 of the adapter 25 can be attached by rotational engagement with the engaging portion 253 of the main body portion 4a as an engagement fulcrum. Using the concave portion 259 of the main body 4a and the convex portion 258 of the adapter 25 in the runner 4, the adapter 25 can be stably integrated with the leading runner 4 even with one mounting screw 32, and the number of parts can be reduced. As a result, the failure rate can be reduced.

  The present invention has been described above with reference to specific embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the technical concept thereof. For example, in the above description, an example in which the cord slack preventing device (adapter 25 and slack preventing cord 26) according to one embodiment of the present invention is applied to the accordion curtain 1 according to one embodiment has been described. If it is a use which needs improvement of the problem of the slack about the predetermined code, it can be applied to a partition device such as an accordion curtain of another form.

  Further, in the cord slack preventing device according to the embodiment described above, the tip portion 262 of the adapter 25 is illustrated in a shape that can be attached by rotational engagement with the locking portion 253 of the main body portion 4a as an engagement fulcrum. However, any shape may be used as long as it can be attached by rotational engagement with the locking portion 253 of the main body 4a as an engagement fulcrum.

  In the cord slack prevention device of the above-described embodiment, the adapter 25 is formed with a grip portion 261 wider than the center portion of the main body to enhance the assembling property when the adapter 25 is engaged with the main body portion 4a. However, any shape may be used as long as it is easy to assemble, and it is not necessarily provided when it can be made unnecessary.

  Moreover, in the cord slack prevention apparatus of one Embodiment mentioned above, although the adapter 25 was demonstrated to be fastened to the main-body part 4a of the top runner 4 with the one attachment screw 32, this form is a suitable example. However, the present invention is not limited to this.

  In the cord slack prevention device of the above-described embodiment, the example in which the slack prevention cord 26 is configured by a single cord has been described. However, the slack prevention cord 26 is configured to include a tension member 26a that generates tension. can do. FIG. 11A is a front view showing a modified example of the slack preventing cord 26 constituting the cord slack preventing device of the embodiment according to the present invention, and FIG. 11B is a cord slack preventing according to the embodiment of the present invention. It is the elements on larger scale regarding the modification of the slack prevention code | cord | chord 26 which comprises an apparatus. This tension member 26a is provided in the vicinity of the cord equalizer 9 within the range of movement in the hanger rail 2 so as to prevent the slack prevention cord 26 itself from loosening.

  In the example shown in FIG. 11B, an example is shown in which the tension member 26 a is configured by a coil spring (tensile spring), and the tension member 26 a is configured to be connected by a cord constituting the slack prevention cord 26. As the tension member 26a, any other member (for example, a rubber material, a cord material that generates a tension, or the like) is used as long as the tension member 26a generates a tension that can prevent the slack of the slack prevention cord 26 itself. be able to. Accordingly, it is a matter of course that even the slack prevention cord 26 provided with a part of the tension member 26a allows the slack prevention cord 26 to slide with respect to the pulley 27.

  More specifically, the operation of the modified example of the slack prevention cord 26 will be described. 12 (a) and 12 (b) are operation explanatory views of the slack prevention cord 26 having the tension member 26a shown in FIG. FIGS. 13A and 13B are operation explanatory diagrams of the slack prevention cord 26 without the tension member 26a.

  First, referring to FIG. 12A, when the cord slack preventing device according to the present invention is configured using the slack preventing cord 26 having the tension member 26a, the cord stopper device is in a state before the operation grip 40 is operated. The traction cord 51 may be slack between the cord 70 and the cord equalizer 9. In this state, as described above, the slack prevention cord 26, the traction cord 51, and the operation cord 42 are configured to move as a series of cords, so that the slack between the adapter 25 and the cord equalizer 9 is achieved. The slack of the prevention cord 26 does not occur. Furthermore, for example, when the tension member 26a is configured by a coil spring (a tension spring), the tension member 26a is extended by a tensile force applied between the adapter 25 and the cord equalizer 9 (attached in the contraction direction). It has a power).

  From the state shown in FIG. 12A, as shown in FIG. 12B, the operation grip 40 is operated in the opening direction of the curtain member 65 to move the operation cord 42 rightward on the hanger rail 2. In the state immediately after, the cord equalizer 9 is pulled and operates to move to the upper right, and the traction cord 51 is not loosened. At this time, the moving rod 7 and the leading runner 4 do not move until the traction cord 51 is loosened, but the tension member 26a has an urging force in the contraction direction, and accordingly the cord equalizer 9 moves. It becomes a deenergized and contracted state, and the tension of the slack prevention cord 26 itself is maintained while the slack of the traction cord 51 is prevented. Thereby, the tension member 26a can prevent the slack prevention cord 26 itself from loosening.

  On the other hand, referring to FIG. 13, the above operation when the slack preventing cord 26 according to the present invention is configured using the slack preventing cord 26 without the tension member 26a will be described as shown in FIG. 13 (a). In addition, in the state before the operation grip 40 is operated, the traction cord 51 may be loosened between the cord stopper device 70 and the cord equalizer 9. In this state, as described above, the slack prevention cord 26, the traction cord 51, and the operation cord 42 are configured to move as a series of cords, so that the slack between the adapter 25 and the cord equalizer 9 is achieved. The slack of the prevention cord 26 does not occur.

  From the state shown in FIG. 13A, as shown in FIG. 13B, the operation grip 40 is operated in the opening direction of the curtain member 65 to move the operation cord 42 rightward on the hanger rail 2. In the state immediately after, the cord equalizer 9 is pulled and operates to move to the upper right, and the traction cord 51 is not loosened. At this time, since the moving rod 7 and the leading runner 4 do not move until the traction cord 51 is free of slack, the slack prevention cord 26 is slackened between the adapter 25 and the cord equalizer 9, and the hanger rail 2 may protrude from the lower surface opening portion, and the functional problem of the cord slack prevention device does not occur, but the aesthetic appearance is impaired.

  Thus, by using the slack prevention cord 26 having the tension member 26a, the function of the cord slack prevention device can be maintained without impairing the beauty.

  According to the present invention, not only the operation by the operation code but also the opening / closing operation of the curtain body can be performed even when the opening / closing operation is performed by the moving rod, and the various codes that are circulated are directly linked including the operation code. Because it is configured in this way, all the cords are allowed to slip with respect to the pulley except where the cord can be intentionally prevented from moving, and the traction cord does not loosen, resulting in durability and poor opening and closing. And the like, and good operability and quality can be maintained, which is useful for applications that need to improve the slackness problem for a given cord.
