Description

  The present invention relates to an opening / closing device for a partition device such as an accordion curtain or a folding door.

  An accordion curtain draws curtain fabric that can be expanded and contracted in a bellows shape between wall surfaces, or folds it on one wall surface side to appropriately divide an indoor space. In such an accordion curtain, when the curtain fabric is pulled out until the operating rod comes into contact with the wall surface, the restoring force acting on the curtain fabric retracts the operating rod and creates a gap with the wall surface.

  Therefore, a fixing device using the magnet's attracting force is provided on the moving rod and the wall surface. If the moving rod is moved until it comes into contact with the wall surface, the fixing device prevents the operating rod from retreating and fully closes the curtain fabric. It is designed to hold the state.

  In an accordion curtain equipped with such a fixing device, if the magnet attracting force is increased, a large operating force is required to pull the operating rod away from the wall surface. On the other hand, if the attractive force of the magnet is weakened, the operating rod cannot be reliably held. Therefore, it is necessary to make it possible to easily pull the operating rod away from the wall surface while ensuring a sufficient suction force.

Patent Documents 1, 2, and 3 disclose a configuration that reduces the operating force during the opening operation of the sliding door by shifting the magnetic pole of the magnet based on the turning operation of the handle. Further, Patent Document 4 discloses a configuration in which an operation force during a sliding door opening operation is reduced by a lever operation by a handle turning operation. Patent Document 5 discloses a configuration in which the accordion curtain is held in an open state by the magnet's attracting force, and the magnet's attracting state is canceled by a handle turning operation.

Made of flexible material. The pressing member 10 is formed so as to protrude from the lower end portion of the handle bar 8 to the side edge portion of the distal end surface of the movable rod 3.

In addition, as shown in FIG. 2, when the handle bar 8 is positioned in the vertical direction, the pressing member 10 comes into contact with the moving rod 3 to prevent the handle bar 8 from rotating in the direction of the column surface 9. ing.
Next, a configuration for rotatably supporting the handle bar 8 on the base portion 7 will be described. As shown in FIG. 4, a support hole 11 is formed in the center of the base portion 7 in the vertical direction. A shaft portion 12 that can be inserted into the support hole 11 is formed at the lower portion of the handle bar 8. Then, the shaft portion 12 is fitted into the support hole 11, and the handle bar 8 is rotatably supported with the support hole 11 as a rotation fulcrum.

  An attachment shaft 13 is formed at the center of the shaft portion 12, and an attachment hole 15 into which a screw 14 can be screwed is formed at the center of the attachment shaft 13. An annular groove 17 into which the torsion coil spring 16 can be inserted is formed around the mounting shaft 13, and a locking projection 18 is formed on the shaft portion 12 on the outer peripheral side of the annular groove 17 in the axial direction of the mounting shaft 13. Is projected along. The locking projection 18 is formed so as to be positioned above the mounting shaft 13 when the handle bar 8 is in the vertical direction.

  On the outer peripheral side of the shaft portion 12, a pair of rotation restricting portions (rotation restricting means) 19 a and 19 b projecting toward the mounting shaft 13 is provided on the base portion 7 in the vertical center line of the base portion 7. In contrast, it is formed in line symmetry. The rotation restricting portions 19 a and 19 b are formed in a range of 60 degrees with respect to the center of the support hole 11.

A torsion coil spring (biasing means) 16 is inserted into the annular groove 17, and one end of the torsion coil spring 16 is in contact with the base portion 7.
A rotation restricting plate (rotation restricting means) 20 made of a metal plate is fixed to the tip surface of the mounting shaft 13. The rotation restricting plate 20 is formed with a through hole 21 through which the screw 14 is inserted at the center, and the screw 14 inserted through the through hole 21 is screwed into the mounting hole 15 to be attached to the mounting shaft 13. Fixed.

  Further, the rotation restricting plate 20 is formed with a locking hole 22 into which the locking protrusion 18 can be fitted, and the attachment shaft 13 in a state where the locking protrusion 18 is fitted in the locking hole 22. It is fixed to. The locking hole 22 is formed to be line symmetric with respect to the center line L in the vertical direction of the rotation restricting plate 20. Therefore, the rotation restricting plate 20 rotates integrally with the mounting shaft 13 and holds the torsion coil spring 16 in the annular groove 17.

  The rotation restricting plate 20 has a holding hole 23 formed on the center line L on the opposite side of the locking hole 22 with respect to the through hole 21, and the other end of the torsion coil spring 16 is formed in the holding hole 23. Is held. Therefore, when the attachment shaft 13 is rotated based on the operation of the handle bar 8 and the rotation restricting plate 20 is rotated along with the rotation of the attachment shaft 13, the torsion coil spring 16 is stored. ing.

  The rotation restricting plate 20 is formed with contact pieces 24a and 24b extending on the outer peripheral side above and below the through hole 21, and on the rotation locus of the contact pieces 24a and 24b. The rotation restricting portions 19a and 19b are located. Then, engagement ends 25a and 25b that contact the rotation restricting portions 19a and 19b are formed at both ends of the contact piece 24a, and engagement ends 25c that contact the rotation restricting portions 19a and 19b at both ends of the contact piece 24b. , 25d.

  As shown in FIG. 3, when the handle bar 8 is positioned in the vertical state, the engagement ends 25b and 25d abut against the rotation restricting portions 19a and 19b, and the engagement ends 25a and 25c and the rotation restricting portions 19a and 19b. A gap of the same width is secured between the two. This gap is generated in a range that forms an angle of approximately 15 degrees with respect to the center of the through hole 21.

  Therefore, when the handle bar 8 is rotated 15 degrees in the direction of arrow A from the state shown in FIG. 3, the engagement ends 25a and 25c come into contact with the rotation restricting portions 19a and 19b as shown in FIG. Further rotation of the rod 8 is prevented. This rotation direction coincides with the direction in which the moving rod 3 is pulled away from the column surface 9.

  When the handle bar 8 is rotated, the torsion coil spring 16 is stored with the rotation of the rotation restricting plate 20. Therefore, when the handle bar 8 is released, the handle bar 8 is returned to the state shown in FIG. 3 by the urging force of the torsion coil spring 16.

  A stopper device (not shown) is provided on the pressing member 10 and the base portion 7 to prevent further rotation of the handle bar 8 when the engagement ends 25a and 25c come into contact with the rotation restricting portions 19a and 19b. No) is provided so that excessive torque does not act on the locking projection 18.

  The operation handle 6 located on the rear surface of the movable rod 3 is composed of common parts except for the pressing member 10. That is, as shown in FIG. 7, it is comprised similarly except the point which the rotation control board 20 is attached in the state which replaced the front and back.

  From the state where the engagement ends 25b and 25d are in contact with the rotation restricting portions 19a and 19b, the handle bar 8 can be rotated within a range of about 15 degrees as indicated by a chain line in FIG. This rotation direction similarly corresponds to the direction in which the moving rod 3 is pulled away from the column surface 9.

As shown in FIG. 2, a cushioning material 26 is fitted to the surface of the movable rod 3 facing the column surface 9, thereby preventing abnormal noise due to collision with the column surface 9.
In addition, the cushion material 26 is cut off at least at two locations above and below the operation handle 6, and magnets (attraction means) 27 are fitted into the cut portions. A yoke plate 28 is exposed on the end surface of the magnet 27, that is, the surface facing the column surface 9.

  As shown in FIG. 5, an attracting plate 29 made of a magnetic material is attached to the column surface 9 at a position facing the magnets 27. When the movable rod 3 is pulled out to the vicinity of the column surface 9 and the yoke plate 28 comes into contact with the suction plate 29, the yoke plate 28 is attracted and held by the suction plate 29 by the suction force of the magnet 27. .

Next, the operation of the accordion curtain configured as described above will be described.
Now, when closing the accordion curtain, the operation handle 6 is operated to move the moving rod 3 toward the column surface 9 side. Then, the main body moves following the moving rod 3 while being stretched. At this time, the handle bar 8 of the operation handle 6 is held vertically as shown in FIG.

  When the movable rod 3 is moved until it comes into contact with the column surface 9, the yoke plate 28 is adsorbed by the adsorption plate 29 and the movable rod 3 is held in close contact with the column surface 9 as shown in FIG. 5. Therefore, in this state, the main body is held in a fully closed state against the restoring force of the surface material 2 and the frame.

  When opening the main body in the fully closed state, the handle bar 8 is rotated in the opening direction of the main body, that is, in the direction of arrow A shown in FIG. Then, the handle bar 8 is rotated in a range until the engagement ends 25a and 25c of the rotation restricting plate 20 come into contact with the rotation restricting portions 19a and 19b.

  When the handle bar 8 is rotated in the direction of arrow A, the pressing member 10 moves toward the column surface 9 and comes into contact with the column surface 9, so that the movable rod 3 rotates around the support shaft 1a as shown in FIG. It is rotated as a moving fulcrum.

By such an operation, one yoke plate 28 close to the operated handle bar 8 is first separated from the suction plate 29, and then the other yoke plate 28 is separated from the suction plate 29.
After the moving rod 3 is pulled away from the suction plate 29, if the moving rod 3 is moved along the hanger rail by the operation of the operation handle 6, the main body is folded to the fixed rod 4 side. If the handle bar 8 is released after the moving rod 3 is moved to a desired position, the handle bar 8 returns to the vertical direction by the biasing force of the torsion coil spring 16.

With the accordion curtain configured as described above, the following operational effects can be obtained.
(1) By operating the operation handle 6, the movable rod 3 can be moved, and the main body of the accordion curtain can be pulled out or folded along the hanger rail.
(2) Since the magnet 27 attached to the movable rod 3 can be attracted to the attracting plate 29 of the column surface 9, the movable rod 3 is brought into close contact with the column surface 9 when the main body is pulled out to the fully closed state. The main body can be held in the fully closed state by being held in the state.
(3) When the main body part is released from the state in which the movable rod 3 is held on the column surface 9, the movable rod 3 is rotated with respect to the column surface 9 by the rotation operation of the operation handle 6. The yoke plate 28 can be sequentially separated from the suction plate 29. Therefore, the operating force for pulling the moving rod 3 away from the column surface 9 can be reduced.
(4) By moving the operating handle 6, the moving rod 3 can be rotated with respect to the column surface 9 by utilizing the lever action. Therefore, the operating force for pulling the moving rod 3 away from the column surface 9 can be reduced.
(5) Since the lever action is used, a required operating force for pulling the movable rod 3 away from the column surface 9 can be ensured without increasing the size of the operating handle 6. Accordingly, it is possible to prevent a decrease in aesthetics or an increase in cost due to an increase in the size of the operation handle 6.
(6) The operation handle 6 attached to both the front and rear surfaces of the movable rod 3 can be composed of common parts except for the pressing member 10. Therefore, the number of parts can be reduced.
(7) In the operation handle 6 attached to the front and rear surfaces of the movable rod 3, the common parts can be used by replacing the rotation restricting plate 20 in the front and back directions.
(8) Since the pressing member 10 of the operation handle 6 is extended to the vicinity of the movable rod 3, even when the width of the column surface 9 is narrow, the pressing member 10 can be reliably brought into contact with the column surface 9.
(9) The torsion coil spring 16 incorporated in the operation handle 6 can automatically return the handle bar 8 in the vertical direction when the operation handle 6 is not operated.
(10) The magnet 27 having one magnetic pole may be disposed only on the moving rod 3, and the arrangement of the magnetic pole is not limited at all. Therefore, the assembling work can be easily performed.
