  In addition, the drawings may be exaggerated by enlarging characteristic portions in order to make the features easy to understand, and the dimensional ratios and the like of the constituent elements are not always the same.

  FIG. 1 is a partially cutaway front view showing a manual shutter device 1 to which an opening / closing direction regulating mechanism 10 is applied. FIG. 2 is an exploded perspective view showing the opening / closing direction regulating mechanism 10. FIG. 3 is a partially omitted cross-sectional view taken along line AA of FIG. FIG. 4 is a left side view showing the flange 11 of FIG. FIG. 5 is a right side view showing the bracket 12, the two-way clutch 13 and the rotary damper 14 of FIG. 2. 6 is a cross-sectional view taken along line BB in FIG.

  The shutter device 1 opens and closes a large area opening such as a garage or a store up and down. The shutter device 1 includes a slat 2 that can be moved up and down, a winding member 3 that winds up the slat 2, and a fixed shaft 4 that is disposed at the rotation center of the winding member 3. The accommodation space 5 for accommodating the slat 2, the winding member 3 and the fixed shaft 4 is covered with an accommodation cover 5a, and is protected without being exposed to wind and rain.

  The slat 2 is configured by slat members 2a disposed adjacent to each other in the vertical direction and hinged via a peristaltic shaft 2b. The upper end of the slat 2 is coupled to the winding member 3 and is configured to be wound around the outer periphery of the winding member 3. Both ends of the slat 2 are accommodated in sliding grooves (not shown) of the guide rail 6 erected on the left and right, so that the fluttering associated with the raising and lowering of the slat 2 is suppressed.

  The winding member 3 is formed in a substantially cylindrical shape. Specifically, the winding member 3 is joined to four shafts 3a extending in the horizontal direction, bearings 3b and 3c press-fitted to the support shaft 4, and one end of the shaft 3a. The wheel 3d is covered with 3b, and the wheel 3e is joined to the other end of the shaft 3a and covered with the bearing 3c. Thereby, when the winding member 3 is rotationally driven in the winding direction (opening direction) D1, the slat 2 is wound up by the winding member 3, and the winding member 3 is anti-winding direction (closed direction). ) When it is rotationally driven by D2, the slat 2 is sent out and descends. The number of shafts 3a is not limited to four, and may be two to three or five or more.

  The fixed shaft 4 is installed between shutter brackets 7 provided on the upper portions of the left and right guide rails 6, and both ends of the fixed shaft 4 are fixedly supported by the shutter bracket 7. A torsion spring (torsion coil spring) 8 is wound around the fixed shaft 4.

  The torsion spring 8 is accommodated in the winding member 3. One end of the torsion spring 8 is fixed to the wheel 3 d, and the other end is fixed to the fixed shaft 4. The torsion spring 8 is urged in the winding direction D1 with respect to the wheel 3d. Thereby, the slat 2 can be raised with a slight force.

  Next, the structure of the opening / closing direction regulating mechanism 10 will be described with reference to the drawings. The opening / closing direction regulating mechanism 10 includes a flange 11 fixed to an end of the fixed shaft 4, a bracket 12 disposed adjacent to the flange 11, and a two-way clutch 13 provided on a side surface of the bracket 12. ing.

  An internal gear 11 b is formed on the facing surface 11 a of the flange 11 facing the bracket 12. The flange 11 is formed in a disc shape, and the flange 11 is fixed to the fixed shaft 4 by the tip of the bolt B screwed into the bolt hole 11 c biting into the fixed shaft 4. Reference numeral 11 d is an insertion hole through which the fixed shaft 4 is inserted.

  The bracket 12 is formed in a cylindrical shape, and the small diameter portion 3d 'of the wheel 3d is inserted through the central hole portion 12a. A two-way clutch 13 is provided on one side surface 12 b facing the flange 11 of the bracket 12. The other side surface 12c of the bracket 12 is joined to the wheel 3d. Therefore, the bracket 12 rotates integrally with the winding member 3 via the wheel 3d.

  A clutch planetary gear 13 b is provided on the input shaft 13 a of the two-way clutch 13. The clutch planetary gear 13b can be engaged with the inner gear 11b of the flange 11. When the bracket 12 is driven to rotate relative to the flange 11, the internal gear 11a of the flange 11 and the clutch planetary gear 13b of the two-way clutch 13 mesh with each other, and the input shaft 13a of the two-way clutch 13 rotates. .

  The two-way clutch 13 has a known configuration, and either the rotation of the winding member 3 along the winding direction D1 (forward rotation) or the rotation of the winding member 3 along the counter-winding direction D2 (reverse rotation). One is allowed and the other is restricted. The rotation direction (lock direction) limited by the two-way clutch 13 can be arbitrarily switched by applying an external force equal to or greater than a predetermined threshold in the direction in which rotation is already limited. A friction switching type or an electric switching type is known as a driving method of the two-way clutch 13, and any of them may be adopted in the present invention. The former can be introduced at a low cost.

  The opening / closing direction regulating mechanism 10 further includes a rotation damper 14. The rotary damper 14 is provided on one side surface 12 b of the bracket 12. A damper planetary external gear 14 b that can mesh with the internal gear 11 b of the flange 11 is provided on the input shaft 14 a of the rotary damper 14. The rotary damper 14 has a known configuration and brakes the rotational movement of the input shaft 14a input via the damper planetary gear 14b. The rotation damper 14 is, for example, an oil damper that brakes the rotation of the input shaft 14a with the viscous resistance of oil. The rotation damper 14 is preferably an infinite rotation damper that decelerates the winding member 3 at least when the winding member 3 rotates in the winding direction D1. If a bidirectional infinite rotation damper is adopted as the rotation damper 14, the raising and lowering of the slat 2 is braked, and the slat 2 is gently raised and lowered. Further, if a one-way infinite rotation damper is adopted as the rotation damper 14, the rise of the slat 2 is braked, the slat 2 is gently raised, and the force for braking the descent of the slat 2 when the slat 2 is lowered ( Since no (damper force) is applied, it can be operated with a light force.

  The two-way clutch 13 and the rotary damper 14 are arranged concentrically around the fixed shaft 4 when viewed from the axial direction of the fixed shaft 4. Note that the number of rotary dampers 14 provided in the opening / closing direction regulating mechanism 10 is not limited to one and may be two or more. When two rotary dampers 14 are provided, it is preferable that the rotary dampers 14 be arranged so as to sandwich the two-way clutch 13.

  The side surface 13 c of the two-way clutch 13 and the side surface 14 c of the rotary damper 14 are substantially flush with each other when viewed from the radial direction of the fixed shaft 4. This prevents the meshing position of the clutch planetary external gear 13b and the internal gear 11b and the meshing position of the damper planetary external gear 14b and the internal gear 11b from being displaced in the axial direction of the fixed shaft 4. 12 can rotate at a substantially constant position with respect to the flange 11.

  The opening / closing direction regulating mechanism 10 is not limited to the above-described configuration. For example, the flange 11 is provided so as to be integrated with the winding member 3, and the bracket 12 is fixed to the fixed shaft 4. It doesn't matter. Further, an external gear (not shown) may be formed on the outer periphery of the bracket 11 instead of the internal gear 11b, and the external gear may be engaged with the clutch planetary external gear 13b and the damper planetary external gear 14b. Absent.

  Next, the operation of the opening / closing direction regulating mechanism 10 will be described. 7A to 7D are partially cutaway front views showing the operation of the opening / closing direction regulating mechanism 10. In the following, a case where the friction switching type two-way clutch 13 is used will be described as an example.

  In a state where the slat 2 is wound around the winding member 3, as shown in FIG. 7A, the two-way clutch 13 restricts the rotation of the winding member 3 along the counter-winding direction D2. In addition, since the torque in the winding direction D1 is always applied to the winding member 3 by the urging force F1 of the torsion spring 8, the clutch planetary external gear 13b is engaged with the internal gear 11b. Is restricted, and the rotational drive of the winding member 3 in the counter-winding direction D2 is limited.

  As shown in FIG. 7B, when an external force F2 in the counter-winding direction D2 that is equal to or greater than a predetermined threshold is applied to the winding member 3 from the state in which the slat 2 is wound around the winding member 3, the two-way The reverse rotation preventing state of the clutch 13 is released, the state shifts to a normal rotation preventing state that restricts the rotation of the winding member 3 along the winding direction D1, and the winding member 3 can be driven to rotate in the counter winding direction D2. It becomes. As a result, the clutch planetary external gear 13b of the two-way clutch 13 and the damper planetary external gear 14b of the rotary damper 14 rotate, and the two-way clutch 13 and the rotary damper 14 rotate around the input shaft 4 in the anti-winding direction D2. By revolving along, the slats 2 can be lowered.

  Next, when the slat 2 is stopped at an arbitrary position, the external force F2 for lowering the slat 2 is removed at the position where the slat 2 is desired to be stopped. This is because, as shown in FIG. 7 (c), the torque in the winding direction D1 due to the urging force F1 of the torsion spring 8 acts, and the two-way clutch 13 limits the forward rotation of the winding member 3. This is because the slat 2 stops at a position where the external force F1 is removed.

  When the slat 2 is lowered again from the temporarily stopped state, the two-way clutch 13 is in the forward rotation prevention state, so that the slat 2 can be lowered again only by applying an external force in the counter-winding direction D2.

  When raising the slat 2 from the paused state, as shown in FIG. 7D, when an external force F3 greater than a predetermined threshold is applied in the winding direction D1 of the winding member 3, the two-way clutch 13 The forward rotation prevention state is canceled, and the reverse rotation prevention state is entered. After the forward-rotation preventing state of the 2-way clutch 13 is released, the clutch planetary external gear 13b of the 2-way clutch 13 and the damper planetary external gear 14b of the rotary damper 14 are rotated by the urging force F1 of the torsion spring 8. The two-way clutch 13 and the rotary damper 14 revolve around the input shaft 4 along the winding direction D1, and the winding member 3 is driven to rotate in the winding direction D1, thereby automatically raising the slats 2. Can do.

  Further, the rotary damper 14 suppresses excessive acceleration of the damper planetary external gear and the winding member 3 due to the urging force applied by the torsion spring 8 to the winding member 3. For example, when a one-way infinite rotation damper that brakes forward rotation of the winding member 3 is installed, the raising operation of the slat 2 is buffered, and the slat 2 can be raised gently. Moreover, when the bidirectional infinite rotation damper which brakes forward rotation and reverse rotation of the winding member 3 is installed, the raising / lowering of the slat 2 is buffered, and the slat 2 can be raised / lowered gently.

  In this way, the opening / closing direction regulating mechanism 10 according to the present invention fixes the planetary external gear 13b for the clutch by applying an external force to the winding member 3 in the direction in which the two-way clutch 13 allows rotation. Since it revolves around the shaft 4 and the winding member 3 and the bracket 12 rotate around the fixed shaft 4, the slat 2 can be raised and lowered. On the other hand, when an external force is applied to the take-up member 3 in the direction in which the two-way clutch 13 prevents rotation, the clutch planetary gear 13b is prevented from revolving around the fixed shaft 4 and is thus taken up. Since the rotation of the member 3 and the bracket 12 around the fixed shaft 4 is prevented, the raising and lowering of the slat 2 is prevented. Further, since the rotation direction of the planetary external gear 13b for the clutch allowed by the 2-way clutch 13, that is, the reverse rotation prevention state and the forward rotation prevention state of the 2-way clutch 13 can be arbitrarily switched, the slat 2 is being raised or lowered. In any case, the slat 2 can be stopped.

When the sliding door 22 and the base member 31 slide relative to the suspension rail 21, the rack 21a of the suspension rail 21 and the clutch pinion 32b of the two-way clutch 32 mesh with each other, and the input shaft 32a of the two-way clutch 32 rotates. To do.

  The two-way clutch 32 has a known configuration, and either the slide along the closing direction D3 in which the hanging door 22 is closed (closing operation) or the sliding along the opening direction D4 in which the hanging door 22 is opened (opening operation). Allow and limit the other. The sliding direction (locking direction) limited by the two-way clutch 32 can be arbitrarily switched by applying an external force equal to or greater than a predetermined threshold in the direction in which the sliding is already limited. As a driving method of the two-way clutch 32, a friction switching type or an electric switching type is known, and any of them may be adopted in the present invention. The former can be introduced at a low cost.

  The opening / closing direction regulating mechanism 30 further includes a rotation damper 33 disposed on the facing surface 31 a of the base member 31 so as to be adjacent to the two-way clutch 32. A damper pinion 33 b provided on the input shaft 33 a of the rotary damper 33 can mesh with the rack 21 a of the suspension rail 21. The rotation damper 33 is, for example, an oil damper that brakes the rotation of the input shaft 33a with the viscous resistance of oil. The rotation damper 33 is preferably an infinite rotation damper that decelerates sliding of the suspension door 22 in the closing direction D3. If a bidirectional infinite rotation damper is adopted as the rotation damper 33, the opening / closing of the hanging door 22 is braked, and the hanging door 22 is opened / closed gently. Moreover, if a one-way infinite rotation damper is employ | adopted for the rotation damper 33, the closing operation of the suspension door 22 will be braked, and the suspension door 22 will close gently.

  Next, the operation of the opening / closing direction regulating mechanism 30 will be described. FIGS. 10A to 10D are schematic views showing the operation of the opening / closing direction regulating mechanism 30. In the following, a case where the friction switching type two-way clutch 32 is used will be described as an example.

  In the state where the suspension door 22 is closed, as shown in FIG. 10A, the two-way clutch 32 is in an open operation blocking state where the sliding along the opening direction D <b> 4 of the suspension door 22 is restricted, and the suspension door 22. The weight F4 in the closing direction D3 acts on the clutch, and the clutch pinion 32b is restricted from biting the rack 21a, and the sliding of the suspension door 22 in the opening direction D4 is restricted.

  As shown in FIG. 10B, when the external force F5 in the opening direction D4 that is equal to or greater than a predetermined threshold is applied to the hanging door 22 from the state in which the hanging door 22 is closed, the open operation blocking state of the two-way clutch 32 is released. Then, the state shifts to a closing operation blocking state in which the sliding along the closing direction D3 of the hanging door 22 is restricted, and the sliding of the hanging door 22 in the opening direction D4 becomes possible. Thereby, the hanging door 22 can be opened.

  Next, when the suspension door 22 is stopped at an arbitrary position, the external force F5 acting on the suspension door 22 is removed at the position where the suspension door 22 is desired to be stopped. This is because, as shown in FIG. 10 (c), the dead weight F4 acts on the hanging door 22, and the two-way clutch 32 restricts the closing operation of the hanging door 22, so the external force is removed from the hanging door 22. This is to stop at the position.

  When the suspension door 22 is reopened from the paused state, the two-way clutch 32 is in the closed operation prevention state, so that the suspension door 22 is reopened only by applying the external force F in the opening direction D4 to the suspension door 22. Can do.

  When the suspension door 22 is closed from the temporarily stopped state, as shown in FIG. 10D, when the external force F6 in the closing direction D3 equal to or greater than a predetermined threshold is applied to the suspension door 22, the closing operation of the two-way clutch 32 is performed. The blocking state is released, and the state shifts to the opening operation blocking state. Then, after releasing the closing operation blocking state of the two-way clutch 32, the hanging door 22 can be automatically slid in the closing direction D3 by its own weight F4.

  Moreover, the rotation damper 33 suppresses that the suspension door 22 accelerates excessively. For example, when a one-way infinite rotation damper that brakes the sliding of the hanging door 22 in the closing direction D3 is installed, the closing operation of the hanging door 22 is buffered, and the hanging door 22 can be closed quietly. Moreover, when the bidirectional infinite rotation damper which brakes the sliding to the opening direction D3 and the closing direction D4 of the hanging door 22 is installed, opening and closing of the hanging door 22 is buffered, and the hanging door 22 can be opened and closed gently. it can.

  In this way, the opening / closing direction regulating mechanism 30 according to the present invention is configured such that the external force is applied to the suspension door 22 in the direction in which the 2-way clutch 32 allows the clutch pinion 32b to rotate. Since the clutch pinion 32b is engaged with the rack 21a of the suspension rail 21, the suspension door 22 can be opened and closed. On the other hand, when the external force is applied to the hanging door 22 in the direction in which the two-way clutch 32 prevents the clutch pinion 32b from rotating, the sliding of the hanging door 22 with respect to the hanging rail 21 is prevented. The sliding of the sliding door 22 is prevented. In addition, since the rotation direction of the clutch pinion 32b allowed by the 2-way clutch 32, that is, the opening prevention state and the closing prevention state of the two-way clutch 32 can be arbitrarily switched, the suspension door 22 is being opened or closed. In any case, the hanging door 22 can be stopped.

  The present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.

  The present invention may be applied to any member as long as the operating member that moves relative to the fixed member is positioned at a desired position.
