JP-A-11-336448 (FIG. 1) Japanese Patent Laid-Open No. 10-46888 (FIG. 1)

  By the way, in Patent Document 2, in order to open and move the shutter curtain in the locked state, it is necessary to first unlock the lock manually. That is, in order to open and move the shutter curtain in the locked state, it is necessary to perform a two-step operation of first manually unlocking the shutter curtain by the locking device and then manually opening and moving the shutter curtain. And

  For this reason, there is a need for an unlocking device for an opening / closing device in which a locking unlocking operation and a shutter curtain opening / moving operation, which are each performed manually, are in a rational relationship.

  An object of the present invention is to provide an unlocking device for an opening / closing device in which the unlocking operation of locking performed manually and the opening / closing operation of an opening / closing body such as a shutter curtain have a rational relationship. is there.

  An unlocking device for an opening / closing device according to the present invention includes an opening / closing body that is openable / closable to partition a space, a locking device that locks the opening / closing body to prevent the opening / closing body from moving, and A handle member provided on the opening / closing body, which is handed to open and move the opening / closing body and is movable in a direction having a component in the opening / closing movement direction of the opening / closing body, and movement of the handle member A moving operation force conversion mechanism that converts an operation force into an action force for unlocking the locking device. The locking device includes a locking member and the opening / closing body by the locking member being locked. The moving operation force conversion mechanism in a direction having a component in the opening movement direction of the opening / closing body with respect to the handle member to open and move the opening / closing body. Perform the move operation The move operation force when, is characterized in that the locking member is converted the to the action force in the direction to cancel the state in which engaged with the engaged member.

  The unlocking device of the opening / closing device is a movement that converts the moving operation force of the handle member that is movable in a direction having a component of the opening / closing movement direction of the opening / closing body into an acting force for unlocking the locking device. The operating force conversion mechanism has an operation force conversion mechanism, and when the moving operation force conversion mechanism performs a moving operation in a direction having a component of the opening / closing body opening movement direction with respect to the handle member to open and move the opening / closing body. The moving operation force is converted into an acting force in a direction to release the state where the locking member is locked to the locked member. For this reason, the locking device can be unlocked at the same time by performing an opening / closing operation of the opening / closing body by the handle member.

  For this reason, according to the present invention, there is a rational relationship between the unlocking operation of the lock and the opening / closing operation of the opening / closing body, which are each performed manually. That is, the unlocking operation of the lock and the opening / closing by the handle member are not required since the lock of the open / close member in the locked state is first unlocked and then the opening / closing member is opened and moved by the hand hung on the handle member. The body opening and moving operation can be performed as a continuous series of operations.

  The opening movement operation of the handle member for opening and moving the opening / closing body may be a rotation around the shaft, a sliding movement, or a combination of these. Any movement operation in the direction having the component is optional.

  The unlocking device of the opening / closing device according to the present invention may include a lock device for preventing the movement operation force from being converted into the acting force by the movement operation force conversion mechanism.

  According to this, the opening / closing body is fully closed by the closing movement, and when this full closing is to be maintained, it is possible to prevent the opening / closing body from opening and moving by mistakenly moving the handle member. it can.

  In the present invention described above, the moving operation force conversion mechanism may be a mechanical type, an electric type, or a combination thereof, and is arbitrary. When the moving operation force conversion mechanism is a mechanical type, the type and structure of the mechanism are arbitrary. For example, a rack and pinion type, a lever type, or a link mechanism type may be used. It may be a thing, a taper cam type, a rotation cam type, etc. may be sufficient.

  As an example of the unlocking device of the opening / closing device according to the present invention, the locking member is arranged to be movable in the width direction in the vicinity of the end in the width direction of the opening / closing member, and the locked member is the opening / closing member of the opening / closing member. In order to guide the opening and closing movement, the end of the opening and closing body in the width direction is arranged on a guide member that is slidably inserted, and the direction of movement of the locking member for unlocking the locking device is the direction of the opening and closing body. It has a width direction, and the handle member can be manually rotated about the axis in a direction having a component in the opening / closing movement direction of the opening / closing body and a component in the thickness direction of the opening / closing body, The conversion mechanism has at least one rotating member that is rotatable about an axis in a direction having a component in the width direction of the opening / closing body, and the rotating member is connected by a locking member and a connecting member. Component of the opening and closing body in the direction of opening movement with respect to the handle member and the front By performing a rotation operation in a direction having a component in the thickness direction of the opening / closing body, at least a part of the handle member comes into contact with the rotating member, and the rotating member that rotates rotates the connecting member of the opening / closing body. By moving the locking member in the width direction, the locking member can be moved in the width direction of the opening / closing body to unlock the locking device.

  According to this, the handle member can be manually rotated around the axis in a direction having a component in the opening / closing movement direction of the opening / closing body and a component in the thickness direction of the opening / closing body. Compared with the case where it is slidable, the operation of moving the handle member becomes easier, and the unlocking operation of the lock and the opening / closing operation of the opening / closing member by the handle member can be performed as a series of continuous operations.

  Here, the shape of the rotating member is arbitrary, but it is preferable that at least a part of the handle member is in contact with the rotating member, and as an example of this, a shape having a portion extending in the width direction of the opening / closing body. Things. On the other hand, the shape of the handle member is arbitrary, but it is preferable that the handle member is in a shape that easily contacts the rotating member. Can be mentioned.

  The movement direction of the locking member when the locking member is unlocked by releasing the locking member that is detachable from the locked member is the inner side of the opening / closing body in the width direction. The direction may be sufficient, and the outer direction of the width direction of an opening-closing body may be sufficient, and it is arbitrary. Similarly, the direction in which the rotating member moves the connecting member to disengage the locking member from the locked member may be the inner side in the width direction of the opening / closing body or the outer side in the width direction of the opening / closing body. Well, optional.

  In the example of the unlocking device of the opening / closing device according to the present invention described above, the opening / closing body may be provided with a locking device for preventing the rotation of the rotating member.

  According to this, the opening / closing body is fully closed by the closing movement, and when this full closing is to be maintained, it is possible to prevent the opening / closing body from opening and moving by mistakenly moving the handle member. it can.

  As an example of the locking device in the unlocking device of the opening / closing device according to the present invention described above, this locking device is provided with a locking member that moves forward and backward in the width direction of the opening / closing body, and the locking member and the rotating member are tensioned. The flexible connecting member is loosely connected, and the flexible connecting member is prevented from turning by rotating the flexible connecting member in the width direction of the opening / closing body. Can be mentioned.

  According to this, when the flexible connecting member connected to the lock member is tensioned in the width direction of the opening / closing body, the rotation member cannot move in the width direction of the opening / closing body. For this reason, even if at least a part of the handle member comes into contact with the rotating member, the movement operation force conversion mechanism does not convert the movement operation force into the action force, and as a result, the locking device is not unlocked. It will not be broken.

  Here, the flexible connecting member may be anything that can be tensioned or relaxed, and is arbitrary, and examples thereof include a wire-like member such as a wire or a synthetic resin string.

  In the present invention described above, the moving operation force conversion mechanism may be provided in the opening / closing body, or may be disposed in a case provided in the opening / closing body, and is arbitrary.

A moving operation force conversion mechanism is provided, an opening is formed at a position where the handle member is provided on the opening and closing body, and an insertion port into which a hand can be inserted is provided at a position corresponding to the opening in the case. It can be mentioned that the handle member can be moved from the other surface side by inserting a hand into the insertion port.

  According to this, the locking device can be unlocked also from the surface opposite to the surface of the opening / closing body provided with the handle member, and the convenience of the unlocking operation can be improved.

  Here, the case may store the entire moving operation conversion mechanism, or may store a part of the moving operation conversion mechanism, and the remaining portion may be arranged outside the case. is there.

  In addition, the shape of the insertion port formed at the location corresponding to the opening in the case may be a square or a rectangle such as a square or a rectangle, may be a circle or a substantially circle, may be an ellipse or a substantially ellipse, Although it is arbitrary, it is more preferable to have a shape in which a hand can be easily inserted. And it is preferable that the magnitude | size of this insertion port has a magnitude | size which a hand inserts easily.

  Similarly, the shape of the opening formed in the opening / closing body where the handle member is provided may be a square or a rectangle such as a square or a rectangle, or a circle or a circle, an ellipse or a substantially ellipse. The shape may be arbitrary and is arbitrary, but it is more preferable that the handle member has a shape that can be easily moved by a hand inserted from the insertion port. And it is preferable that the size of this opening part has a magnitude | size which is easy to move and operate a handle member with the hand inserted from the insertion port.

  In the present invention described above, when the locking device is provided in the unlocking device of the opening / closing device, the locking device and the handle member are located in the middle of the opening / closing movement direction of the opening / closing body when fully closed and at the same position in the opening / closing movement direction. The locking device may be operable from at least the outer space of the outer space and the inner space partitioned by the opening / closing body when fully closed.

  According to this, in the case where the opening / closing body opens and closes the doorway, for example, the locking device can be operated from the outside of the doorway. When the conversion mechanism is in a locked state, in other words, even when the conversion by the moving operation force conversion mechanism is blocked by the locking device, the locked state by the locking device is released from the outside of the entrance / exit. Thereby, the opening / closing operation of the opening / closing body by the handle member can be performed from the outside of the entrance / exit.

  In the above, the number of the handle members provided in the opening / closing body may be one or plural and arbitrary. In addition, what formed the handle part of a handle member so that the width direction full length of an opening / closing body may be included in setting the number of the handle members provided in an opening / closing body to one.

  Further, the opening / closing movement direction of the opening / closing body may be a vertical vertical direction, a horizontal direction, or an oblique direction that forms an angle with respect to the vertical vertical direction, and is arbitrary.

  The present invention described above can be applied to an opening / closing device having an arbitrary opening / closing body that can be freely opened and closed to partition a space. For example, the opening / closing body that can be opened and closed is a shutter curtain. Other examples are shutter devices that are installed at eaves such as storefronts, and can be opened and closed. And sliding doors.

  When the present invention is applied to a shutter device, the shutter device may be an opening shutter device that opens and closes openings such as windows and doorways with a shutter curtain, and a disaster prevention shutter for forming a disaster prevention zone with the shutter curtain. It may be a device, a garage shutter device, a storage shutter device, a vehicle loading platform, a shutter device for a container, or the like.

  Thus, in the present embodiment, the pair of left and right arm portions 10C of the handle member 10 serves as a cam for transmitting the moving operation force of the handle member 10 to the pair of left and right rotating members 15 and 17, This is a moving operation force transmission unit for transmitting the moving operation force of the handle member 10 to the moving operation force conversion mechanism 12. For this reason, the moving operation force conversion mechanism 12 according to the present embodiment is a rotating cam type mechanical type.

  As shown in FIG. 3, in order to make the opening movement of the shutter curtain 1 impossible on the end side in the length direction of the slat 9A, in other words, on the end side in the width direction of the shutter curtain 1 in the slat 9A. A locking device 20 for locking the shutter curtain 1 is provided. The locking device 20 includes a locking member 21 connected to an extension member 51 described later, which is connected to a rotation member 15 on the right side of the moving operation force conversion mechanism 12 via a wire 31 that is a flexible connection member. The locking member 21 disposed in the vicinity of the end of the slat 9A in the length direction is to be locked, and has a locked member 22 disposed in the guide rail 4. ing.

  Further, the lock device 11 is provided with a lock member 26 that advances and retreats toward the outer side in the width direction of the shutter curtain 1.

  In FIG. 8, similarly to the handle member 10, the moving operation force conversion mechanism 12, and the locking member 21, a pair of left and right lock members 26 provided on the lock device 11 advance from the main body 11 </ b> A side of the lock device 11 to the handle member 10 side. FIG. 9 shows the time when these lock members 26 are retracted toward the main body 11A. FIG. 10 shows the lock device 11 as viewed from the front surface side of the shutter curtain 1, and FIG. 11 shows a cross-sectional view of the lock device 11.

  The rotor 41 shown in FIG. 11 is fitted to the outer peripheral portion of the rotary plug 40 having the key hole 40A into which the plate key shown in FIG. 10 is inserted, and when the plate key is inserted into the key hole 40A, the rotary plug 40 The first tumbler (not shown) that has stopped rotating is retracted, and the second tumbler (not shown) that connects the rotary plug 40 and the rotor 41 protrudes. For this reason, the rotary plug 40 and the rotor 41 can be rotated by the rotation operation of the plate key inserted into the keyhole 40A. Since the rotor 41 is formed with the teeth 43 shown in FIG. 11 that mesh with the rack teeth 42 of the pair of lock members 26 shown in FIG. 10, the rotor 41 is rotated 180 degrees in one direction by rotating the plate key. Then, the pair of lock members 26 change from the state of FIG. 8 to the state of FIG. 9, and when the rotor 41 is further rotated 180 degrees in the other direction, the pair of lock members 26 returns to the state of FIG.

  When the pair of lock members 26 are in the state shown in FIG. 8, one end is connected to a through hole 26B formed in the lock member 26 and the other end is on the left side of the moving operation force conversion mechanism 12 shown in FIG. Since the wire 30 connected to the through hole 17C formed in the lower part of the rotating member 17 is in a relaxed state as shown in FIG. Thus, the handle member 10 can be rotated in the front side of the shutter curtain 1. Thereby, the locking device 20 can be unlocked as described later.

  On the other hand, when the pair of lock members 26 are in the state shown in FIG. 9, the wire 30 is pulled by the lock member 26 and is in a tensioned state as shown in FIG. The rotation of the rotation member 17 is prevented, and as will be described later, it is impossible to perform the rotation operation to the front side of the shutter curtain 1 with respect to the handle member 10. That is, the rotating member 17 is locked by the lock device 11, so that the locking device 20 cannot be unlocked as will be described later.

  In addition, for example, when the shutter curtain 1 opens and closes the entrance / exit of the store, the plate key is separated from the surface side of the shutter curtain 1, in other words, the store that is partitioned by the fully closed shutter curtain 1. The store is operated from the outer space of the entrance / exit space and the outer space of the doorway, but as shown in FIG. 11, on the back side of the shutter curtain 1, in other words, the store partitioned by the shutter curtain 1 A rotation operation member 44 that is rotated by hand is provided on the back surface of the lock device 11 that faces the inner space of the doorway. The rotation operation member 44 passes through the cover member 45 of the locking device 11 and is coupled to the rotor 41, and a finger is applied to a portion exposed from the cover member 45 as shown in FIGS. Two finger-hanging portions 44A that can be hung and rotated are provided at a separation angle of 180 degrees. A recess 47 into which a small protrusion 46 formed on the cover member 45 is fitted is formed on the surface of the finger-hanging portion 44 </ b> A that faces the cover member 45.

  When the pair of lock members 26 are in the state shown in FIG. 8, the rotation operation member 44 is rotated 180 degrees while these small protrusions 46 are moved over by elastic deformation of the finger-hanging portion 44 </ b> A, and then the depression 47 is again inserted. When the small protrusions 46 are fitted, the rotor 41 also rotates 180 degrees with respect to the rotary plug 40, so that the pair of lock members 26 are in the state shown in FIG. When the rotation operation member 44 is rotated 180 degrees to the opposite side, the pair of lock members 26 returns to the state shown in FIG.

  As described above, the lock device 11 according to this embodiment can be operated from the front surface side and the back surface side of the shutter curtain 1.

  As shown in FIG. 3, the locking member 21 of the locking device 20 has an inner end in the width direction of the shutter curtain 1 at the end of the locking member 21 in the width direction of the shutter curtain 1. An extension member 51 having a length in the direction is connected. FIG. 12 is an enlarged view of the periphery of the connecting portion between the locking member 21 and the extension member 51, and FIG. 13 is a cross-sectional view taken along line S13-S13 in FIG.

  A portion of the extending member 51 in the width direction of the shutter curtain 1 is formed on the base member 52 by a base member 52 fixed to the slat 9A where the handle member 10 is disposed and a bent piece 52A of the base member 52. The extension member 51 is inserted into the space portion between the coupled cover members 53 having a channel shape in cross section and penetrates in the width direction of the shutter curtain 1. Guided by two side wall portions 53A provided in the opening / closing movement direction, the shutter curtain 1 is movable in the width direction.

  Further, as shown in FIG. 13, the extension member 51 is formed with a cut-and-raised protrusion 51A, and the base member 52 is also formed with a cut-and-raised protrusion 52B. These protrusions 51A and 52B are The extending member 51 is always elastically biased outward in the width direction of the shutter curtain 1 by the installed spring 54.

  The extension member 51 is provided with two standing pieces 51C rising from the base surface 51B that is slidably in contact with the base member 52 in the opening / closing movement direction of the shutter curtain 1, and these standing pieces 51C are locked to the extension member 51C. A notch 51D is formed in which the rotation center 21A of the locking member 21 forming the device 20 is rotatably inserted and engaged. The locking member 21 is curved in the thickness direction of the shutter curtain 1 from the rotation center portion 21A. Further, at the end of the base member 52 protruding from the cover member 53 to the outer side in the width direction of the shutter curtain 1, a raised portion 52C that is raised in the thickness direction of the shutter curtain 1 by bending is formed. 13, when the extension member 51 reaches the outer end position of the shutter curtain 1 in the width direction by the spring 54, the locking member 21 is greatly increased by riding on the raised portion 52 </ b> C. Projects in the thickness direction.

  On the other hand, when the extension member 51 moves back inward in the width direction of the shutter curtain 1 against the spring 54, the locking member 21 also moves back as shown in FIG.

  15 is a plan sectional view of the slat 9A and the guide rail 4 as viewed from above, and FIG. 16 is a sectional view taken along line S16-S16 in FIG. As shown in FIG. 16, a locked member 22 that forms the locking device 20 together with the locking member 21 is disposed on the side surface inside the guide rail 4. The locked member 22 is provided with an inclined surface 22A inclined downward in the thickness direction of the shutter curtain 1 and an engaging surface 22B formed horizontally or substantially horizontally at the lower end of the inclined surface 22A. Yes. Further, the lower surface of the distal end portion of the locking member 21 is an inclined surface 21 </ b> B that is inclined downward in the thickness direction of the shutter curtain 1.

  As shown in FIGS. 3 and 7, one end of the wire 31 is connected to the through hole 15 </ b> C formed in the lower part of the rotating member 15 on the right side of the moving operation force conversion mechanism 12. The other end of the wire 31 is connected to a through hole 51 </ b> E having a vertically long and substantially rectangular shape formed at the outer end of the extending member 51 in the width direction of the shutter curtain 1.

  In the above, when the lock member 26 of the lock device 11 is in the state shown in FIG. 8, when the shutter curtain 1 in the fully open position or the half open position is closed and moved as described above, it is shown in FIGS. As shown in FIG. 16, the inclined surface 21B of the locking member 21 that is always elastically biased outwardly in the width direction of the shutter curtain 1 by the spring 54 contacts the inclined surface 22A of the locked member 22. The locking member 21 and the extending member 51 are retracted inward in the width direction of the shutter curtain 1 by the guide action of the inclined surfaces 21B and 22A due to the contact. Then, at the same time that the locking member 21 passes the position of the locked member 22, the locking member 21 and the like are returned to their original positions by the elastic force of the spring 54, which is indicated by a two-dot chain line 21 'in FIG. Since the upper surface of the locking member 21 faces the locking surface 22B at the lower end of the locked member 22 up and down, the upward movement of the shutter curtain 1 The shutter curtain 1 is blocked by the locking device 20 constituted by the member 22, in other words, the shutter curtain 1 is locked by the locking device 20 in which the locking member 21 is locked to the locked member 22, and this locking is automatically performed. Made. At this time, the shutter curtain 1 has reached the fully closed position.

    After the shutter curtain 1 is fully closed and locked as described above, the lock member 26 of the lock device 11 is operated by operating the plate key from the front surface side of the shutter curtain 1 or the rotation operation member from the back surface side. When the state of FIG. 9 is obtained by the operation of 44, the wire 30 is pulled by the lock member 26 and is in a tensioned state as shown in FIG. For this reason, since the rotation of the left rotation member 17 of the moving operation force conversion mechanism 12 is prevented, the handle member 10 cannot be rotated in the front direction on the front side of the shutter curtain 1. The shutter curtain 1 is locked.

  Next, operations of the moving operation force conversion mechanism 12 and the locking device 20 when the handle member 10 is rotated to open and move the shutter curtain 1 will be described.

  When the shutter curtain 1 is opened and moved, first, the lock member 26 of the lock device 11 is brought into the state shown in FIG. At this time, the wire 30 having one end connected to the through hole 26B of the lock member 26 and the other end connected to the through hole 17C of the left rotation member 17 of the moving operation force conversion mechanism 12 is shown in FIG. As shown in FIG. 5, it is in a relaxed state, and therefore, the rotation member 17 on the left side of the moving operation force conversion mechanism 12 shown in FIG. On the other hand, the wire 31 whose one end is connected to the through hole 51E of the extension member 51 of the locking device 20 and whose other end is connected to the through hole 15C of the right turning member 15 of the moving operation force conversion mechanism 12 is described above. Thus, since the extension member 51 is always elastically biased outward in the width direction of the shutter curtain 1 by the spring 54 of the locking device 20, as shown in FIG. 3 and FIG. .

  Next, as shown in FIG. 6, while hooking a finger on the finger hook portion 10B of the hook member 10, as shown in FIG. 6, the shutter curtain 1 rotates toward the front side of the shutter curtain 1 (the direction of arrow A shown in FIG. 6). Perform the action. Then, as shown in FIG. 6, the pair of left and right arm portions 10 </ b> C of the handle member 10 also rotate.

  Therefore, as shown in FIG. 4, the lower surface of the right arm portion 10C of the handle member 10 that is in contact with the upper surface 16A of the protruding portion 16 of the right rotation member 15 of the moving operation force conversion mechanism 12 is shown in FIG. As shown, the projection 16 is pushed down. Thereby, the right rotation member 15 is rotated in the direction of arrow B. Similarly, the lower surface of the left arm portion 10C of the handle member 10 that has been in contact with the upper portion 18A of the protruding portion 18 of the left rotating member 17 of the moving operation force converting mechanism 12 also pushes down the protruding portion 18, so that the left side The rotating member 17 rotates in the direction of arrow C.

  At this time, the wire 30 that is connected in a relaxed state to the through hole 17C of the left rotation member 17 at one end is pulled in the direction of arrow E.

  On the other hand, the wire 31 whose one end is connected to the through hole 15C of the right rotation member 15 is pulled in the arrow D direction. Since the other end of the wire 31 is connected to the through hole 51E of the extension member 51 of the locking device 20, as a result, the extension member 51 moves inward in the width direction of the shutter curtain 1, and at the same time, the extension member. The locking member 21 to which 51 is connected also moves inward in the width direction of the shutter curtain 1 against the spring 54, and the locking member 21 reaches a position where it is detached from the locked member 22. That is, the locking of the shutter curtain 1 by the locking device 20 is unlocked.

  In addition, as shown in FIG. 7, when the pair of left and right rotating members 15 and 17 are rotated, the left end of the spring 19 connecting the two rotating members 15 and 17 is The left rotation member 17 is pulled in the arrow G direction, and the right end is pulled in the arrow F direction by the right rotation member 15. For this reason, while the handle member 10 is being rotated, a spring force in the direction opposite to the arrow G direction is accumulated at the left end of the spring 19, and the direction opposite to the arrow F direction is accumulated at the right end of the spring 19. The spring force in the direction is accumulated.

  The handle member 10 after the shutter curtain 1 is unlocked by the locking device 20 functions as a handle portion for opening and moving the shutter curtain 1. That is, when the handle member 10 is lifted up slightly, the shutter curtain 1 starts to open and move. Then, the shutter curtain 1 is wound around the winding shaft 6 shown in FIG. 1 and moves open, and this opening movement is performed while the rotation of the winding shaft 6 is assisted by the accumulated pressure of the return spring described above.

  If the hand is released from the handle member 10 during the opening movement of the shutter curtain 1, the pair of left and right rotating members 15 and 17 that have been rotated will return to the original state shown in FIG. Return to. As a result, the pair of left and right arm portions 10C of the handle member 10 that has pushed down the protruding portions 16 and 18 of the pair of left and right rotating members 15 and 17 are conversely the upper surfaces of the protruding portions 16 and 18 of the rotating members 15 and 17. Since it is pushed up by 16A, 18A, the handle member 10 also returns to the original state shown in FIG.

  Furthermore, when the wire 31 connected to the through hole 15C of the right rotation member 15 is pulled in the direction of arrow D, the extension member 51 and the locking member that have been retracted inward in the width direction of the shutter curtain 1 21, the wire 31 is pulled in the direction opposite to the arrow D direction, thereby moving forward in the width direction of the shutter curtain 1 and returning to the original state shown in FIG.

  In this embodiment described above, the unlocking device of the shutter device performs a rotation operation in a direction having a component in the opening movement direction of the shutter curtain 1 and a component in the width direction of the shutter curtain 1 with respect to the handle member 10. It has a moving operation force conversion mechanism 12 that converts the moving operation force when performed into an acting force in a direction to release the state in which the locking member 21 of the locking device 20 is locked to the locked member 22. ing.

  For this reason, according to the present embodiment, there is a rational relationship between the unlocking operation of the locking device 20 and the opening / moving operation of the shutter curtain 1 which are each performed manually. That is, after the unlocking of the shutter curtain 1 in the locked state is first performed, the two-stage operation of opening and moving the shutter curtain 1 with the hand hung on the handle member 10 becomes unnecessary, and the unlocking operation of the locking device 20 is not required. And the opening movement operation of the shutter curtain 1 by the handle member 10 can be performed as a continuous series of operations.

  In the present embodiment, the moving operation force conversion mechanism 12 housed in the case 13 is provided at a position corresponding to the handle member 10 on the back surface side of the shutter curtain 1, and the handle member 10 in the shutter curtain 1 is An opening 9B is formed at the provided position, and an insertion port 13D into which a hand can be inserted is formed at a position corresponding to the opening 9B in the case 13.

  For this reason, according to this embodiment, it becomes possible to rotate the handle member 10 from the back side of the shutter curtain 1 by inserting a hand into the insertion port 13D. That is, the unlocking operation of the locking device 20 can also be performed from the back side of the shutter curtain 1, and the convenience of the unlocking operation can be improved.

  Furthermore, according to this embodiment, the shutter curtain 1 is provided with the lock device 11 for preventing the rotation of the rotation member 17 on the left side of the movement operation force conversion mechanism 12, so that the shutter curtain is closed and moved. Thus, when the fully closed state is to be maintained, it is possible to prevent the handle member 10 from being erroneously rotated and the shutter curtain 1 to open and move.

  FIGS. 17-22 is a figure which shows the handle member and movement operation force conversion mechanism which concern on another embodiment. 17 is a partially enlarged front view of the slat 9A, and FIG. 18 is a rear view of FIG.

  In the present embodiment, the locking device and the locking device, which are devices other than the handle member and the moving operation force conversion mechanism, are the same as the locking device 11 and the locking device 20 according to the above-described embodiment. Description is omitted. Hereinafter, the handle member 110 and the moving operation force conversion mechanism 112 according to the present embodiment will be described.
