Description

  The present invention relates to an unlocking device for unlocking by opening and closing a locking member of an opening / closing body by operating a handle member provided on the opening / closing body, for example, manually moving a shutter curtain to open and move manually It can be used for various types of shutter devices such as an opening type shutter device and a shutter device for disaster prevention, and also for an opening / closing device such as an awning device used for awning or the like.

  A shutter device having a shutter curtain that is an openable and closable body that can be opened and closed in a vertical direction is provided with a handle on the shutter curtain, and a manual shutter device that opens and closes the shutter curtain with a hand that is hung on the handle (For example, Patent Document 1 below).

In addition, the present applicant arranges two handle members on the shutter curtain in the width direction of the shutter curtain which is the left and right direction, makes these handle members movable in the width direction of the shutter curtain, and is guided by the guide member. When the shutter curtain that has reached the fully closed position is automatically locked by the locking device, the locking device is unlocked by moving the handle member connected to the locking device via the connecting mechanism. A shutter device has been proposed in which the shutter curtain can be opened and moved by applying a lifting force to the handle member (Patent Document 2 below).
Japanese Patent Laid-Open No. 11-336448 (FIG. 1) Japanese Patent Application 2002-335980 (FIG. 4)

  In the shutter device of Patent Document 2, the shutter curtain is unlocked by the locking device by moving the two handle members inward in the width direction of the shutter curtain. After that, the shutter curtain is opened and moved as it is by these handle members, so that the distance between the two handle members after the moving operation and the opening and moving operation of the shutter curtain by these handle members resist the weight of the shutter curtain. Thus, there is a rational relationship in manually performing this opening movement, and it is required to make this opening movement easier.

  The object of the present invention is that the distance between the two handle members after the moving operation and the opening / closing operation of the opening / closing body such as the shutter curtain by these handle members are rationally related to the weight of the opening / closing body. An object of the present invention is to provide an unlocking device for an opening / closing device.

  An unlocking device for an opening / closing apparatus according to the present invention includes an opening / closing body that can be opened and closed in a direction having a vertical component, and a locking device that locks the opening / closing body in order to prevent the opening / closing body from opening and closing. And an opening / closing device unlocking device provided with two on the opening / closing body in the width direction of the opening / closing body, which is the left-right direction, and a handle member that is hooked to open and move the opening / closing body And at least one of the two handle members is movable in the width direction of the opening / closing body to unlock the lock device, and the handle member is used to unlock the lock device. Therefore, the distance between the two handle members when the moving operation is performed in the width direction of the opening / closing body is larger than that before the moving operation.

  In the unlocking device of the opening / closing device, at least one of the two handle members is freely movable in the width direction of the opening / closing body to unlock the locking device. Since the distance between the two handle members when moving in the width direction of the opening / closing body for unlocking is larger than before the movement operation, at least one handle member is moved in the width direction of the opening / closing body. As a result, the locking device that locks the opening / closing body can be unlocked, and when the lifting force is applied to the two handle members to open and move the opening / closing body following this moving operation, The distance between these hanging members is large. For this reason, the opening / closing movement of the opening / closing body that is manually performed against the weight of the opening / closing body can be performed while maintaining a good weight balance between the left and right sides of the opening / closing body.

  Therefore, according to the present invention, the distance between the two handle members after the moving operation and the opening / closing operation of the opening / closing member by these handle members have a rational relationship with respect to the weight of the opening / closing member. Since the opening / closing body can be opened and moved by manual operation while maintaining a good weight balance between the left and right sides of the body, the opening / closing operation can be easily performed.

  In the above, the handle member that can be moved in the width direction of the opening / closing body in order to unlock the locking device may be only one of the two or both. When one handle member can be moved and operated in the width direction of the opening / closing body in order to unlock the locking device, the remaining handle member may be arranged on the opening / closing body so as not to be movable. You may arrange | position so that movement operation is possible in the width direction of an opening-and-closing body for the other purpose which is not for making it unlock.

  In the case where the two handle members are movable in the width direction of the opening / closing body in order to unlock the locking device, the movement operation direction for unlocking the locking device is set for both of these handle members. The opening / closing body may be located outside in the width direction, or, for one handle member, the moving operation direction for unlocking the locking device is set to the outside in the width direction of the opening / closing body, and the locking device is used for the other handle member. The moving operation direction for unlocking may be the inner side in the width direction of the opening / closing body.

  Even in the latter case, since the distance between the two handle members after the moving operation is larger than that before the moving operation, the opening / closing body can be moved by manual operation while maintaining a good weight balance between the left and right sides of the opening / closing body. It becomes easy to do.

  In addition, the two handle members can be freely moved in the width direction of the opening / closing body to unlock the locking device, and the movement operation direction for unlocking the locking device can be opened / closed for both of these handle members. In the case of the outer side in the width direction of the body, the positions of the two handle members when moved to the outer side in the width direction of the opening / closing body to unlock the locking device are left and right from the center position in the width direction of the opening / closing body. Although the positions may be unequal distances in the direction, it is preferable that the distribution positions are equal distances or substantially equal distances in the left-right direction from the center position in the width direction of the opening / closing body.

  According to this, when a lifting force is applied to the two handle members to open and move the opening / closing body, the weight of the opening / closing body is applied to the left and right hands equally or substantially equally. This can be done while further improving the weight balance.

  In addition, the position of the two handle members when the locking device is unlocked in this way is a distribution position that is equidistant or substantially equidistant in the left-right direction from the center position in the width direction of the opening and closing body, When only one of the two handle members can be moved and operated in the width direction of the opening / closing body, or the movement operation direction for unlocking the locking device is the width direction outside of the opening / closing body for one handle member, The other handle member is preferable even when it is located inside the opening / closing body in the width direction.

  In addition, the interval between the two handle members when the locking device is unlocked, in other words, the interval between the two handle members when the opening / closing body is opened and moved is opened and closed from the left and right hands to these handle members. It is preferable to set the interval at which the body lifting force can be applied satisfactorily. This interval is, for example, a dimension between the shoulder width and the interval between these hands when both hands are spread, that is, about 40 cm to 150 cm. More specifically, a dimension of about 50 cm to 100 cm is preferable.

  Further, the height positions of the two handle members before or after unlocking the locking device may be the same or substantially the same, so that the operation of unlocking the locking device is not so hindered. There may be a step in the height position. When the opening / closing body is a shutter curtain of the shutter device and the shutter curtain is formed to include a plurality of slats arranged vertically, the two handle members may be provided on the same slat. Although it is preferable, they may be provided in separate slats.

  The operation direction for unlocking the locking device for one of the two handle members may be the vertical direction. Furthermore, the operation direction for unlocking the locking device for at least one of the two handle members may be an oblique direction that is a combined direction of the width direction and the vertical direction of the opening / closing body.

  In the above, the arrangement position of the locking device is arbitrary. That is, the locking device may be disposed across the counterpart member that contacts when the opening / closing body is fully closed and the opening / closing body, and the width of the opening / closing body to guide the opening / closing movement of the opening / closing body. An opening / closing device using a guide member such as a guide rail in which an end portion in a direction is slidably inserted may be disposed across the guide member and the opening / closing body.

  In addition, the structure of the locking device is also arbitrary. For example, in the case where the locking device is disposed across the guide member and the opening / closing body as described above, the locking device is arranged with the width of the opening / closing body. A locking member that is arranged to be movable in the width direction in the vicinity of the end of the direction, and is connected to the handle member whose movement direction for unlocking the locking device is on the outer side in the width direction of the opening / closing body by a connecting mechanism And a locked member that locks the opening / closing body when the locking member is locked.

  In this locking device, when the movement direction of the locking member for locking to the locking member to lock the opening / closing body is inside the width direction of the opening / closing body, the locking with the locking member is released. Then, the movement direction of the locking member for unlocking the opening / closing body is the outside in the width direction of the opening / closing body, so that the handle member and the locking member are connected by the connecting mechanism having a simple structure. Thus, when the handle member is moved to the outside in the width direction of the opening / closing body, the locking member may be configured to move to the outside in the width direction of the opening / closing body.

  On the other hand, when the movement direction of the locking member for locking the opening / closing body by locking to the locked member is outside the width direction of the opening / closing body, the locking with the locked member is released to open / close Since the moving direction of the locking member for unlocking the body is the inner side in the width direction of the opening / closing body, the moving operation of the handle member to the outer side in the width direction of the opening / closing body is performed on the connecting member. The movement direction conversion means for converting the movement of the opening / closing body into the inner side in the width direction is provided, and when the handle member is moved outward in the width direction of the opening / closing body by this conversion means, the locking member is moved in the width direction of the opening / closing body It is only necessary to move inward so that the locking of the opening / closing body by the locking device is unlocked.

  In this way, when the moving direction converting means is provided in the coupling mechanism, the type, structure, etc. of the moving direction converting means are arbitrary. For example, a rack and pinion type, a lever type, or a link mechanism may be used. The type may be a taper cam type or the like.

  Moreover, it is preferable that the connecting mechanism that connects the handle member and the locking member is provided with a moving operation force accumulating means for accumulating the moving operation force from the handle member and transmitting it to the locking member.

  According to this, even if the handle member is moved suddenly, this operation is once accumulated by the moving operation force accumulating means and then transmitted to the locking member. For this reason, the operating feeling of the handle member is a good feeling with cushioning properties, and the locking member is locked to the locked member with a large frictional force, so that the locking member is covered with a small force. Even if it is in a state where it does not move in a direction away from the locking member, the locking member can be moved in a direction away from the locked member by a large force once accumulated by the moving operation force accumulating means. It becomes possible to release the locking of the member from the locked member more reliably.

  In the above description, the opening / closing movement direction of the opening / closing body may be a vertical up / down direction or a direction having an inclination angle with respect to the vertical up / down direction. That is, the present invention can be applied to an opening / closing device in which the opening / closing body can be opened and closed in a direction having a vertical component, and the opening / closing body is opened and moved against its weight.

  Further, the present invention as described above can be applied to an opening / closing device including an arbitrary opening / closing body that opens and closes, one example of which is a shutter device including a shutter curtain that opens and closes, and another example is a storefront or the like. It is an awning device equipped with a curtain for sunshade and rain protection that is installed at the eaves and can be opened and closed freely.

  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. The disaster prevention shutter device includes an elevator disaster prevention shutter device in which a shutter curtain moves between an elevator and an elevator hall when a disaster such as a fire occurs.

  In addition, the shutter curtain in the shutter device may be formed by connecting a plurality of slats or a main part of the shutter curtain, or may be formed by connecting a plurality of panels. It may be formed of a pipe, may be formed of a thin member such as cloth, may be formed of a net, or may be formed of at least two of these.

  Furthermore, the form for storing the opening / closing body such as the shutter curtain that has moved open may be a winding system with a take-up shaft, a form in which the opening / closing body is folded, or a form in which components of the opening / closing body are separated and stacked. Alternatively, the opening / closing body may be sent and moved as it is or in a deformed state such as a curve.

  In addition, in an opening / closing device that winds an opening / closing body such as a shutter curtain with a winding shaft, an elastic member such as a coil spring or a spiral spring that accumulates pressure when the opening / closing body is fed out by rotating the winding shaft is wound. It may be arranged on the inner periphery or the outer periphery of the take-up shaft, and the take-up shaft for taking up the opening / closing body may be rotated while using the accumulated pressure of the elastic member as an auxiliary force.

  In general, the opening / closing device to which the present invention can be applied is of a type in which the opening / closing body such as a shutter curtain is manually moved. However, the present invention is not limited to this, and the opening / closing body of the opening / closing body is not limited thereto. In addition to having an automatic function in which movement is performed by driving means such as an electric motor, the present invention can also be applied to a switchgear that can also be manually operated during a power failure.

  According to the present invention, the distance between the two handle members after the moving operation and the opening / closing operation of the opening / closing body by these handle members have a rational relationship with respect to the weight of the opening / closing body, and Therefore, the opening / closing body can be easily opened and moved by manual operation.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on drawing. FIG. 1 is an overall front view of an opening shutter device serving as an opening / closing device according to the present embodiment, and shows a state where a shutter curtain 1 serving as an opening / closing body is fully closed.

Both end portions in the width direction are slidably inserted. A shutter case 5 is provided in the upper part of the opening 2, and a winding shaft 6 is supported by a pair of left and right brackets 7 inside the shutter case 5 so as to be rotatably accommodated. The upper end of 1 is joined. The end of the shutter curtain 1 on the closing side, in other words, the lower end of the shutter curtain 1 is a seat plate 8, and a number of slats 9 are arranged vertically on the upper end of the seat plate 8. The shutter curtain 1 is a slat type whose main part is formed by connecting a large number of slats 9.

  The height of the lintel where the shutter curtain 1 is guided by the pair of guide rails 4 and rises, and the seat plate 8 forms a lower surface of the shutter case 5 and is provided with a slit through which the shutter curtain 1 is inserted vertically. Until the shutter curtain 1 reaches the position, the shutter curtain 1 is wound around the winding shaft 6 so that the shutter curtain 1 fully opens the opening 2. Further, when the lower end of the operation rod such as the engagement rod is engaged with the seat plate 8 and the pulling operation is performed, the shutter curtain 1 is drawn out from the take-up shaft 6 while rotating the take-up shaft 6 and moves. When the seat plate 8 contacts the floor 2A of the opening 2, the shutter curtain 1 fully closes the opening 2.

  When the shutter curtain 1 is drawn out from the take-up shaft 6 in this way, a return spring (not shown) disposed on the rotating take-up shaft 6 is accumulated, so that the shutter curtain 1 is in the fully closed position or in the middle position where it is fully closed. When the shutter curtain 1 that has been stopped is raised to be opened and moved manually, the shutter curtain 1 can be raised slightly by this accumulated pressure.

  Among a large number of slats 9 forming the shutter curtain 1, a predetermined slat 9A, that is, a slat 9A that is substantially at the height of the waist when the shutter curtain 1 is fully closed, The handle member 10 made of synthetic resin or metal, which is a member that forms a part of the handle portion to be opened and moved by manual operation, is arranged in the width direction of the shutter curtain 1 in the left-right direction. One is provided. The arrangement positions of these handle members 10 are distribution positions that are equidistant or substantially equidistant from the center position in the width direction of the shutter curtain 1. The slat 9A is also provided with a lock device 11 at a central position between the two handle members 10.

In addition, another handle member 10 is provided, and members, mechanisms, means, devices, and the like related to the handle member 10 are also arranged in a laterally symmetrical positional relationship in the width direction of the shutter curtain 1. That is, except for the lock device 11, the same members, mechanisms, means, devices, and the like are arranged symmetrically in the width direction of the shutter curtain 1.

  The following description will be made on one handle member 10 and members, mechanisms, means, devices, and the like related to the handle member 10.

  As shown in FIG. 3, the slat 9A is provided with a hole 12 formed so as to penetrate the front and back of the slat 9A, and a hole on the surface side of the slat 9A corresponding to the hole 12 has a hole. A handle base member 13 provided with an opening 18 having the same or substantially the same size and shape as the portion 12 is disposed. The handle base member 13 which forms a handle portion of the shutter curtain 1 together with the handle member 10 is attached to the slat 9A by the locking action of the taper protrusion 14A of the leg portion 14 inserted into the hole of the slat 9A. It is fixed. The handle member 10 is disposed at a position on the back surface side of the slat 9A corresponding to the hole portion 12. The handle member 10 includes a flange portion 15 facing the slat 9A and the handle base member 13 together with the flange portion 15. A guide portion 17 is formed to hold the provided engaging projection 16 in the thickness direction of the shutter curtain 1. This holding is performed so that the handle member 10 can slide in the width direction of the shutter curtain 1. The member 10 is movable in the width direction of the shutter curtain 1 with respect to the slat 9A and the handle base member 13.

  As described above, the handle base member 13 is formed with the opening 18 having a size and shape corresponding to the hole 12 of the slat 9A, and the handle member 10 has these openings. A recess 19 is provided through which the hand can be inserted from the surface side of the shutter curtain 1 through the hole 18 and the hole 12. As shown in FIG. 2, the interval between the wall portions 19 </ b> A on both sides in the width direction of the shutter curtain 1 in the recessed portion 19 that is recessed in the thickness direction of the shutter curtain 1 is the wall portion on both sides in the same direction of the opening 18. For this reason, the wall portion 19 </ b> A of the concave portion 19 is at a position inside the opening portion 18.

  Accordingly, the wall member 19A is pushed by the hand inserted into the concave portion 19 from the surface side of the shutter curtain 1 through the opening 18 and the hole portion 12, so that the handle member 10 is moved from the surface side of the shutter curtain 1 to the width of the shutter curtain 1. It can be moved in the direction. Further, since the handle member 10 is disposed on the back surface side of the slat 9 </ b> A, the handle member 10 can be moved and operated in the width direction of the shutter curtain 1 from the back surface side of the shutter curtain 1.

  In addition, a concave finger-hanging portion that can be hooked with a finger is formed on one or both of the upper and lower flange portions 10C and 10D on the back surface of the handle member 10 shown in FIG. 3, and this finger-hanging portion is used. Thus, the handle member 10 may be moved from the back side of the shutter curtain 1.

Further, when the lock member 26 of the lock device 11 is in the state shown in FIG. 5, when the handle member 10 is moved outward in the width direction of the shutter curtain 1, the pinion 32 and the rack portions 31A and 51E are formed. Due to the rack and pinion mechanism, the locking member 21 moves inward in the width direction of the shutter curtain 1.

  Therefore, the connecting mechanism 30 is provided with a rack and pinion type moving direction converting means 33 that converts the movement of the handle member 10 to the opposite side of the width direction of the shutter curtain 1 and transmits it to the locking member 21.

  In the above, when the lock member 26 of the lock device 11 is in the state shown in FIG. 5, 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. 13, the inclined surface 21B of the locking member 21 that is constantly elastically biased outward in the width direction of the shutter curtain 1 by the spring 54 contacts the inclined surface 22A of the locked member 22, Due to the guiding action of the inclined surfaces 21 </ b> B and 22 </ b> A due to this contact, the locking member 21 and the extending member 51 are retracted inward in the width direction of the shutter curtain 1 against the spring 54. 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 up and down the locking surface 22B at the lower end of the locked member 22, the upward movement of the shutter curtain 1 causes the locking member 21 and the locked member to move upward. 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. The 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. In the state shown in FIG. 6 by the operation of 44, the handle member 10 cannot be moved to the outside in the width direction of the shutter curtain 1, so that the locking of the shutter curtain 1 by the locking device 20 is locked.

  When the shutter curtain 1 is opened and moved, the lock member 26 of the lock device 11 is brought into the state shown in FIG. 5 with the plate key or the rotation operation member 44, and then the handle member 10 is moved to the outside in the width direction of the shutter curtain 1. As a result, the locking member 21 is moved inward in the width direction of the shutter curtain 1 against the spring 54 by the rack-and-pinion type moving direction converting means 33, and the locking member 21 is detached from the locked member 22. Reach position. That is, the locking of the shutter curtain 1 by the locking device 20 is unlocked.

  Then, when a lifting force is applied to the handle member 10 as it is, the shutter curtain 1 is wound around the winding shaft 6 shown in FIG. 1 and moves open, and this opening movement is performed by the above-described return spring accumulated pressure. The rotation of the shaft 6 is performed with assistance.

  As described above, unlocking the locking by the locking device 20 and opening and moving the shutter curtain 1 simultaneously operates the two handle members 10 arranged on the left and right of the slats 9A of the shutter curtain 1 as described above. Is done by.

  According to the present embodiment described above, in order to open and move the shutter curtain 1 locked by the locking device 20, the two handle members 10 arranged on the left and right sides of the slats 9 </ b> A of the shutter curtain 1 are attached to the shutter curtain 1. Since the lifting force is applied to these handle members 10 after the movement operation is temporarily performed to the outside in the width direction, thereby unlocking the lock by the locking device 20, the two handle members 10 when the lifting force is applied. This interval is larger than before the moving operation.

  For this reason, the opening movement of the shutter curtain 1 that is manually performed against the weight of the shutter curtain 1 can be performed while maintaining the right and left weight balance of the shutter curtain 1 even though it is assisted by the accumulated pressure of the return spring. Thus, the interval between the two handle members 10 after the moving operation and the opening and moving operation of the shutter curtain 1 by these handle members 10 can be rationally related to the weight of the shutter curtain 1. .

  Further, the interval between the two handle members 10 after the movement operation, that is, the interval between the two handle members 10 when the locking device 20 is unlocked, is determined from the center position of the shutter curtain 1 in the width direction. Since it is a sorting position that is equidistant or substantially equidistant in the direction, the shutter curtain 1 can be opened and moved by these handle members 10 while further improving the balance of the left and right weights of the shutter curtain 1 in both hands. Can do.

  Further, the locking member 21 of the locking device 20 is locked to the engaged member 22 to lock the shutter curtain 1 by moving the locking member 21 to the outside in the width direction of the shutter curtain 1. Even if it is, the connecting mechanism 30 for connecting the handle member 10 and the locking member 21 is provided with the moving direction converting means 33, and the moving direction converting means 33 allows the shutter curtain 1 of the handle member 10 to be moved. Since the movement operation to the outer side in the width direction can be converted into the movement to the inner side in the width direction of the shutter curtain 1 with respect to the locking member 21 whose locking with the locked member 22 is released, the shutter curtain 1 is The movement operation of the two handle members 10 that is performed at the time of the opening movement can be performed on the outer side in the width direction of the shutter curtain 1.

  FIG. 14 shows moving direction conversion means according to another embodiment, and FIG. 15 is a partially enlarged view of FIG. In this embodiment, the handle member 10 and the locking member 21 of the locking device 20 are connected by a connecting mechanism 60. The connecting mechanism 60 includes a connecting member 61 that replaces the connecting member 31 in the above embodiment, and the above-described embodiment. An extension member 81 is used instead of the extension member 51 in the embodiment.

  In addition, the base member 82 of this embodiment, which replaces the base member 52 of the above-described embodiment, has a step 82A at a position shifted from the cover member 53 inward in the width direction of the shutter curtain 1 in the thickness direction of the shutter curtain 1. A stepped flat portion 82B that is bent to form a gap with the slat 9A is provided. A portion 61A on the outer side in the width direction of the shutter curtain 1 in the connecting member 61 is inserted between the stepped flat portion 82B and the slat 9A, and a portion 81A on the inner side in the width direction of the shutter curtain 1 in the extension member 81 is stepped. It is arranged on the surface side of the flat portion 82B, that is, on the side opposite to the portion 61A of the connecting member 61 across the stepped flat portion 82B.

  Between the portion 61A of the connecting member 61 and the portion 81A of the extension member 81, a moving direction conversion means 63 is interposed by two coil-type springs 62. These springs 62 are rotatably supported on the stepped flat portion 82B by a shaft 64 inserted in the coil portion of FIG. One end 62A of the spring 62 faces the portion 61A of the connecting member 61 in the width direction of the shutter curtain 1, and the other end 62B of the spring 62 is inserted into a hole formed in the portion 81A of the extension member 81.

  When the handle member 10 is moved to the outside in the width direction of the shutter curtain 1, the portion 61A of the connecting member 61 presses one end 62A of the spring 62 in the same direction to rotate the spring 62 around the shaft 64. Due to the other end 62 </ b> B of the spring 62 that moves inward in the width direction of the shutter curtain 1, the locking member 21 also moves inward in the width direction of the shutter curtain 1 through the extension member 81. Thereby, the locking member 21 is detached from the locked member 22 of the locking device 20, and the locking of the shutter curtain 1 by the locking device 20 is unlocked.

  As described above, the moving direction converting means 63 according to this embodiment is of a lever type by the spring 62 having the shaft 64 as the center of rotation.

  Further, according to this embodiment, when the handle member 10 is moved outward in the width direction of the shutter curtain 1 in order to unlock the locking device 20, the moving operation force is applied via the spring 62 which is an elastic member. Therefore, after the spring force is accumulated in the spring 62 by the moving operation force from the handle member 10, the moving operation force is transmitted to the locked member 62 as this accumulated pressure. For this reason, even if the handle member 10 is moved suddenly, the operating feeling of the handle member 10 becomes good with cushioning properties due to the spring 62 serving as the moving operation force accumulating means 65.

  Further, since the locking member 21 is locked to the locked member 22 with a large frictional force, the locking member 21 is not moved in a direction away from the locked member 22 with a small force. In this case, if the handle member 10 is moved, the locking member 21 can be moved away from the locked member 22 by the force once accumulated by the moving operation force accumulating means 65 and increased. The locking member 21 can be detached from the locked member 22, that is, the locking of the shutter curtain 1 by the locking device 20 can be more reliably performed.
