  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 9a for attaching one end of the operation cord 42 and one end of the slack prevention cord 26, and two traction cords 51a and 51b (collectively referred to as “traction cord 51”). And a second connecting portion 9b for attaching each 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 tow cords 51a and 51b attached to the second connecting portion 9b provided at one end of the cord equalizer 9 are turned downward via the pulley 52 and passed through the cord stopper device 70, the tow cord 51a Is turned 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 is connected to the left end substantially parallel to the longitudinal direction of the hanger rail 2 via the pulley unit 12. Turn to the right end. 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 be inserted through the portion, and is attached to the first connecting portion 9 a 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 9b 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. Similarly, the traction cord 51 b that has passed through the cord stopper device 70 is turned by the pulley unit 12 and is locked by a cord adjuster (not shown) fixed to the movable rod 7. The slack prevention cord 26 attached to the first connecting portion 9a 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 is passed through the pulley 27 in the operation unit 6. Connected to the adapter 25.

  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 rotational fitting. 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.

  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 74 has a double drum structure, and a rotating drum 74a is positioned on the outer side in contact with the traction cord 51, and a brake drum 74b is positioned 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 further detailed description thereof 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.
