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.

  An object of the present invention is to provide an opening / closing device that is provided with a partition member that can be expanded and contracted, and that can reduce the operating force during an opening operation in a partition device that holds the partition member in a fully closed state based on the suction force of the suction means. There is to do.

  An embodiment of a partition device embodying the present invention will be described below with reference to the drawings. The accordion curtain shown in FIG. 1 has a body portion (partition member) formed by attaching a surface material 2 to both front and rear sides of a framework 1 that expands and contracts in a pantograph shape, and a moving rod 3 is attached to a support shaft 1a at one end of the framework 1. Is attached so as to be capable of relative rotation, and a fixing rod 4 is attached to the support shaft 1b at the other end so as to be capable of relative rotation.

  The fixed rod 4 is fixed to the wall surface 5, and an operation handle 6 is attached to the center in the vertical direction on both front and rear surfaces of the movable rod 3.

  The frame 1 is suspended and supported on a hanger rail via a plurality of runners, and the frame 1 and the surface material 2 can be expanded and contracted along the hanger rail by operating the operation handle 6.

  As shown in FIGS. 2 to 4, the operation handle 6 is supported so that the lower end of a round bar-like handle shaft 7 can be rotated with respect to the moving rod 3 with the rotating shaft 8 as a fulcrum. 2 can be rotated within a predetermined angle range from the state shown in FIG. 2 to the state shown in FIG.

  A pressing member 10 is formed at the lower end of the handle shaft 7 so as to protrude toward a column surface (opposing surface) 9 that faces the movable rod 3, and the pressing member 10 is formed of a rubber-like flexible material. The pressing member 10 is configured to protrude in a range from the lower end portion of the handle shaft 7 to the vicinity of the movable rod 3.

  As shown in FIGS. 3 and 5, a torsion coil spring 12 is disposed in the rotating shaft 8 as an urging means, and one end 13a of the torsion coil spring 12 is fixed to the rotating shaft 8 and the other end. Reference numeral 13 b is fixed to the movable rod 3. When the handle shaft 7 is rotated from the state shown in FIG. 5 as shown in FIG. 6, the torsion coil spring 12 is accumulated, and after the handle shaft 7 is released by the urging force, the state shown in FIG. It comes to return.

  A cushioning material 11 is fitted to the movable rod 3 on the surface facing the column surface 9 to prevent the generation of noise due to the collision with the column surface 9.

  Further, as shown in FIG. 4, the cushion material 11 is cut out at at least two places above and below the operation handle 6, and magnets (attraction means) 14 are fitted into the cut portions. A yoke plate 15 is exposed on the end surface of the magnet 14, that is, the surface facing the column surface 9.

  On the column surface 9, a suction plate 16 made of a magnetic material is attached at a position facing the magnets 14. When the movable rod 3 is pulled out to the vicinity of the column surface 9 and the yoke plate 15 comes into contact with the suction plate 16, the yoke plate 15 is attracted and held by the suction plate 16 by the suction force of the magnet 14. .

  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 shaft 7 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 15 is attracted to the suction plate 16 and the movable rod 3 is held in close contact with the column surface 9 as shown in FIG. 4. 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, as shown in FIG. 6, the operation handle 6 is rotated in the opening direction of the main body. Then, since the pressing member 10 comes into contact with the column surface 9, the movable rod 3 is rotated with the support shaft 1b as a rotation fulcrum as shown in FIG.

  By such an operation, first, one yoke plate 15 close to the operated handle shaft 7 is first separated from the suction plate 16, and then the other yoke plate 15 is separated from the suction plate 16.

  After the moving rod 3 is pulled away from the suction plate 16, 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.

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 14 attached to the movable rod 3 can be attracted to the attracting plate 16 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 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 15 can be sequentially separated from the suction plate 16. 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) 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.
(7) The torsion coil spring 12 incorporated in the operation handle 6 can automatically return the handle shaft 7 in the vertical direction when the operation handle 6 is not operated.
(8) The magnet 14 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.
