Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a partition device for an accordion curtain, a folding door or the like.

  An accordion curtain, a folding door or the like partitions an indoor space appropriately by pulling out a partition member made of a curtain material or the like that can be expanded and contracted in a bellows-like manner between wall surfaces or folding it into one wall surface side.

  In such a partition device, a plurality of runners movable in the hanger rail are used to suspend and support the partition member.

  For example, in an accordion curtain, a curtain material is attached to a pantograph-like expanding / contracting frame to constitute a curtain body, and a movable rod is rotatably attached to a support shaft at one end of this structure, and a support shaft at the other end The fixed rod is attached to be relatively rotatable. The fixed rod is fixed to the wall surface, and by moving the moving rod, the curtain body can be extended and contracted along the hanger rail.

  By the way, in such a partition device, it is often used to open and close the curtain material by connecting a plurality of cords. Such multiple cords are often connected using a predetermined connecting member. For example, the connection member is detachably configured to connect or disconnect one end of a plurality of relatively thin cords and one end of a relatively thick operation cord, thereby ensuring safety during operation, construction time or maintenance Workability at times can be improved.

  Therefore, in order to attach the cords to be connected to the connection member, insertion holes for inserting a plurality of cords are respectively provided in the connection member, and balls are connected to the ends of the cords inserted through the insertion holes. The technique of attaching by providing is known (for example, refer patent documents 1, 2).

  In the technique of Patent Document 1, a tie ball is provided at the end of each cord to be coupled, and is configured to be attached to each of the detachable coupling members (safety devices).

  In the technique of Patent Document 2, the inner connecting member and the outer cylindrical member constitute a connecting member, and a knot ball is provided at the end of each cord to be connected and detachably locked at both ends of the inner connecting member. By making the inner connection member storable, the detachable connection member is configured.

  As described above, in the techniques of Patent Documents 1 and 2, the connecting member is configured to be attached by providing a tie ball at the end of each cord, and it serves to prevent the detachment of each cord. . However, in these techniques, in the case of a cord with a large cord diameter (for example, an operation cord etc.), the tie ball inevitably becomes large, and the connecting member needs to have a space for accommodating the tie ball, so that the size increases. become.

  Such enlargement of the connecting member unnecessarily increases the side width of the dividing device, for example, when the connecting member is used in the inside of the dividing device or in the outer peripheral part that affects the installation of the dividing device. It is possible to press down the living space and to make the vertical length or the horizontal length of the partition device unnecessarily short, and it is possible to narrow the open space of the curtain material when the partition device is installed. Unfavorable.

  Furthermore, the use of the connecting member itself can improve the safety at the time of operation or the workability at the time of construction or maintenance, but each time a cord is attached to the connecting member, a tie ball is formed It has to be done, and it can not be said that the workability is good.

  Therefore, there is a need for a technique for reducing the size of the connecting member even when attaching a cord having a large diameter (e.g., an operation cord) and improving the work efficiency regarding the attachment of the cord to the connecting member.

  An object of the present invention is to provide a partition device for connecting a plurality of cords used for opening and closing the partition member in view of the above-mentioned problems.

The partition device according to the present invention is a partition device capable of operating the movement of the partition member along the hanger rail, and an operation cord whose one end can be pulled to perform opening / closing operation of the partition member, and the operation cord code equalizer connecting the other end, one end connected to an end of the moving direction of the partition member, and the traction cord to connect the other end to said cord equalizer, one end to the end of the moving direction of the partition member And a third cord connecting the other end to the code equalizer, and the traction equalizer and the third cord are endlessly formed by the code equalizer through the end in the moving direction of the partition member. It is connected to, and wherein the cord equalizer is in association with the pulling operation so as to move along the hanger rail That.

  According to the present invention, it is possible to improve the safety at the time of operation, or the workability at the time of construction or maintenance, and provide a winding shaft that enables the cord to be locked by winding and folding the cord. Therefore, even when a cord with a large diameter (e.g., an operation code or the like) is attached, it is possible to miniaturize the code equalizer as the connecting member. Furthermore, according to the present invention, the end of the cord can be easily locked to the cord equalizer by the tightening, the work efficiency regarding attachment of the cord can be improved, and the workability can be improved.

  The operation cord 42 is a string-like member, and the 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 to have a diameter smaller than that of the operation cord 42. That is, although the slack prevention code 26 and the traction cords 51a and 51b do not need to be operated by the operator, the operation code 42 is provided for the operation of the operator, so the diameter thereof is set large. Further, the traction cords 51a and 51b pass through the cord stopper device 70 secured to the fixed rod 8 via the pulley 52 in the turning pulley unit 10 secured to the upper end portion of the fixed rod 8 and are pulled downward. The diameter of the cords 51 a and 51 b is smaller than the diameter of the operation cord 42.

  Here, the paths of the operation cord 42, the traction cords 51a and 51b, and the slack prevention cord 26 will be described again. When advancing 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 inner side of the bracket 15 along the longitudinal direction at the upper part of the hanger rail 2 by the operation pulley 43 The direction is turned so as to insert the part, and is attached to the first connecting part 9 a of the code equalizer 9 together with the slack prevention code 26.

  The two traction cords 51a and 51b attached to the second connecting portion 9b of the code equalizer 9 are fixed to the fixed rod 8 via the pulleys 52 in the turning pulley unit 10 fixed to the upper end of the fixed rod 8 Pass through the cord stopper device 70. The traction cord 51 a which has passed the cord stopper device 70 is turned by the pulley unit 11 and locked by the cord adjuster 13 fixed to the moving rod 7. Similarly, the traction cord 51b passing through the cord stopper device 70 is also turned by the pulley unit 12 and locked by a cord adjuster (not shown) fixed to the moving rod 7. The slack prevention cord 26 attached to the first connecting portion 9 a of the code equalizer 9 is directed to the operation unit 6 along the longitudinal direction at the upper part of the hanger rail 2 via the pulley 27 in the operation unit 6. It is connected to the mobile crane 7.

  Thereby, when the operation grip 40 is operated and the operation cord 42 moves to the right at the upper part of the hanger rail 2, the cord equalizer 9 moves to the right and the traction cord 51 also moves, so the traction cord 51 also moves At the same time, the moving rod 7 moves in the left direction (the opening direction of the curtain member 65). Since the slack prevention cord 26 connected to the leading runner 4 fixed to the upper end of the moving rod 7 is pulled along with the movement of the moving rod 7 in the left direction, the rightward movement of the code equalizer 9 is assisted. Come to work together.

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

  The plurality of coil springs 64 bias the curtain member 65 in the closing direction, and between the substantially parallel link pieces 60 (the front link piece and the rear link piece) which constitute the respective rhombus portions as the framework, It connects in the vicinity of the peak part which protrudes in a mountain shape in the thickness direction of the material 65, and is arrange | positioned by several places (refer 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 framework is folded and biasing force is stored in the plurality of coil springs 64. In this state, when the operating grip 40 is released, when the clutch operation for blocking the moving state of the tow cord 51 functions by the cord stopper device 70, the curtain member 65 is maintained in the open state at the stop position of the moving rod 7. Ru. On the other hand, when releasing the operation grip 40, the moving rod 7 abuts on the mounting frame 5 by the biasing force of the coil spring 64 when the clutch operation which allows the movement state of the pulling cord 51 by the cord stopper device 70 functions. Automatically move to the fully closed state.

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

  The bracket 15 is a member for positioning and fixing the hanger rail 2 with respect 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 with the central portion of the main body of the bracket 15 as a rotation fulcrum. The fixing portion has a shape 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 movement state of the traction cord 51 in accordance with the movement action of the traction cord 51 passing through the inside (that is, in accordance with the movement action of the operation cord 42 by the operation of the operator) It is a device that performs so-called clutch operation that switches whether locking is performed to prevent the movement state, and is provided to enhance operability. However, since the code stopper device 70 has no direct relationship with the code equalizer 9 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 rotatable 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 biasing force of the spring 73. The clutch mechanism 72 has a drum 74 rotatable in the moving direction of the pulling cord 51 (as will be described later, the drum 74 has a double drum structure of a rotating drum 74 a and a brake drum 74 b). The drum 74 has a clutch operation function of blocking or permitting movement of the traction cord 51 in accordance with predetermined movement of the operation cord 42. Also, 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 relative to the clutch mechanism 72 so as to be movable in the left-right direction. Therefore, the traction cord 51 inserted between the pulley 76 and the drum 74 is pressed by the biasing force of the spring 73.

  The drum has a double drum structure, and the rotary drum 74a is located on the outer side in contact with the pulling cord 51, and the brake drum 74b is located on the inner side. The brake drum 74 b is non-rotatably supported by the clutch mechanism 72. The outer surface of the rotating drum 74a has a surface shape with high friction, and the inner surface has a surface shape with high sliding property. In addition, the outer surface of the brake drum 74b also has a highly slidable surface shape. Furthermore, since the pulley 76 also has a high friction surface shape, the pulling cord 51 is pressed between the pulley 76 and the drum 74 by the biasing force of the spring 73, thereby enabling the clutch operation.

  In describing the clutch operation, the clutch ball 75 is disposed between the inner surface of the rotary drum 74a and the outer surface of the brake drum 74b. Therefore, the axial direction of the rotary drum 74a is That is, a guide groove (not shown) for guiding the movement of the clutch ball 75 is provided on the accordion curtain 1 in the front-rear direction. Further, on the outer surface of the brake drum 74b, a guide groove (not shown) is provided to apply the clutch operation.

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

  Therefore, the clutch ball 75 is movably guided in the guide groove of the brake drum 74b while being restricted by the guide groove of the rotary drum 74a.

  When the operation grip 42 pulls down the operating cord 42 against the biasing force of the coil spring 64 by the operation grip 40, the movement groove (the movement of the clutch ball 75) in which the clutch ball 75 constitutes a part of the guide groove The rotating drum 74a is allowed to rotate in the direction (the opening direction of the curtain member 65) of moving the pulling cord 51 passing through the inside of the cord stopper device 70 upward while moving around the inside of the unconstrained groove). Here, if the operating grip 40 is released from the state where the clutch ball 75 is positioned in the moving groove, in the direction (the closing direction of the curtain member 65) the pulling cord 51 moves downward by the biasing force of the coil spring 64. When the clutch ball 75 starts moving and moves into the stop groove (the groove that restrains the movement of the clutch ball 75) forming a part of the guide groove and engages with the end point in the stop groove, the rotating drum 74a The rotation is blocked and the curtain material 65 is stopped at the desired position.

  Subsequently, the operating grip 40 slightly pulls the operating cord 42 against the biasing force of the coil spring 64 from the state where the clutch ball 75 engages with the end point and the curtain member 65 stops at the desired position. After rotating the rotary drum 74a within the range of a predetermined angle, if the operation grip 40 is released, the pulling cord 51 is moved downward (the closing direction of the curtain member 65) by the biasing force of the coil spring 64. The clutch ball 75 moves to the moving groove, and as the rotary drum 74a rotates, the clutch ball 75 circulates in the moving groove, and the curtain member 65 automatically moves in the closing direction.

  Further, when the operation cord 42 is further pulled down against the biasing force of the coil spring 64 from the state where the curtain member 65 is stopped at the desired position, and the rotary drum 74a is rotated by a predetermined angle or more, the clutch ball 75 The rotation of the rotary drum 74a is permitted by moving from the stop groove into the moving groove and releasing the operation grip 40 in this state, the clutch ball 75 is in the stop groove by the rotation of the rotary drum 74a by the biasing force of the coil spring 64. 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 can be found, for example, in Japanese Patent Publications in which it is configured as a take-up shaft instead of the rotating drum 74a, and as a pull-up groove and a pull-down groove See, for example, the contents disclosed in Japanese Patent Application Laid-Open 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 does not pinch and damage the finger or hand of a third party other than the operator when the moving rod 7 moves in the direction of the mounting frame 5 Or it is a shock absorbing device (damper device) which stops. The soft-close device 80 is not an essential component to realize the function of the accordion curtain 1 and has no direct relationship with the code equalizer 9 according to the present invention, so a further detailed description will be omitted. .

  The accordion curtain 1 configured in this way is not a structure for grasping the handle and pulling out the curtain body, but a structure for pulling out the curtain body via the operation cord, so there is no need for the operator to move along with the movement of the moving rod. For example, the pull-out operation in a state where the wheelchair user is faced is also facilitated, and the operability is improved.

  Further, in order to directly open and close the accordion curtain 1 by 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. As compared with the partition device, a direct feeling of operation occurs, so that the operability is improved.

(Configuration of code equalizer)
Next, the configuration of the code equalizer 9 (the first connecting portion 9a and the second connecting portion 9b) according to an embodiment of the present invention will be described in detail. The code equalizer 9 (the first connecting portion 9a and the second connecting portion 9b) of this embodiment has a configuration suitable for forming the accordion curtain 1 as described above.

  The code equalizer 9 (the first connecting portion 9a and the second connecting portion 9b) of the present embodiment includes a plurality of codes (the operation code 42, the slack prevention code 26 and the pulling cords 51a and 51b) used to open and close the curtain body 14. It is an apparatus comprised as a connection member which enables connection. Here, as described above, the slack prevention cord 26 and the traction cords 51 a and 51 b are provided to have a diameter smaller than that of the operation cord 42. Since the operation code 42 relates to the operation of the operator, the diameter is large.

  FIGS. 4A and 4B are perspective views of the first connecting portion 9a and the second connecting portion 9b that constitute the code equalizer 9 according to the embodiment of the present invention.
