I can judge. In addition, as a case where the operator determines the locking / unlocking state of the opening / closing body by touching the mark portion of the finger-hanging portion, for example, when the operator locks / unlocks the opening / closing body in a dark room or A case where the operator has low vision or the like can be given.

  As described above, according to the first invention, it is possible to easily determine whether the opening / closing body is locked or unlocked.

  In the first invention, the shape and structure of the mark portion provided on the finger-hanging portion are arbitrary, and the locking member is locked or detached from the locked member, that is, the opening / closing body is locked or unlocked easily. Anything that can be judged is acceptable.

  As an example of the mark portion, an arrow indicating a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member can be given.

  According to this, by looking at the direction of the arrow, it is possible to easily determine whether the locking member is locked or detached from the locked member.

  In addition, in the first invention, the form and structure of the finger-hanging portion are arbitrary as long as they can be hooked with a finger, for example, a circular shape or a substantially circular shape centering on the rotation center portion of the rotation operation member. The shape may be a shape, or may be an elongated shape that is long in a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member.

  Here, the mark portion in the former case is, for example, a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member from or near the rotation center portion of the rotation operation member in the finger hanging portion (in other words, in other words, And an arrow indicating a radial direction), a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member from a position away from the rotation center of the rotation operation member in the finger hook (in other words, May be an arrow indicating a radial direction), passes through a rotation center portion of the rotation operation member in the finger hanging portion, and is a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member (in other words, the diameter direction). Or a graphic mark (for example, a graphic such as a circle, an ellipse, or a rectangle) provided at a position away from the center of rotation of the rotation operation member in the finger hook.

  Further, the mark portion in the latter case may be, for example, an arrow indicating the longitudinal direction of the finger hanging portion from a position away from the rotation center portion of the turning operation member in the finger hanging portion. An arrow indicating the longitudinal direction of the finger hanging portion may be an arrow indicating the longitudinal direction of the finger hanging portion, or an arrow indicating the longitudinal direction of the finger hanging portion through the rotation central portion of the rotating operation member in the finger hanging portion. May be an arrow indicating a direction orthogonal to or substantially orthogonal to the longitudinal direction of the finger-hanging portion through the rotation center portion of the rotation-operating member in FIG. A graphic mark (for example, a graphic such as a circular shape, an elliptical shape, or a rectangular shape) provided at the position may be used.

  The mark portion may be engraved on the finger hanging portion, or may be a label having the shape of the mark portion, a label on which the mark portion is written, affixed to the finger hanging portion, or the like. . Further, the mark portion may be provided so as to be recessed with respect to the finger hanging portion, or may be provided so as to protrude from the finger hanging portion. Furthermore, the mark portion may be colored or may not be colored.

  A locking device for an opening / closing device according to a second aspect of the present invention is an opening / closing body that can be opened and closed, a locking member that is movably disposed on the opening / closing body, and an immobility that is stationary relative to the opening / closing body. The engagement member is disposed on a member, and the engagement member can be engaged and disengaged, and the engagement member is engaged to prevent the opening and closing movement of the opening and closing body, thereby locking the opening and closing body. A locking device main body is disposed on the stop member and the opening / closing body, and a lock that moves relative to the locking device main body when a rotating operation member provided on the locking device main body is rotated by a finger. And a locking device that selects the locking and the detachment of the locking member with respect to the locked member by the locking member, and the rotation operation member is configured to rotate the locking member. Hang the finger to rotate the operating member In the locking device of the opening / closing device having a finger hooking portion, the finger hooking portion has a shape having directivity in a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member. It is characterized by being.

  In the second invention, the finger-hanging portion itself has a directivity in a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member. That is, the locking state or the detaching state of the locking member with respect to the locked member, in other words, the locked state or unlocked state of the opening / closing body can be understood from the direction indicated by the finger-hanging portion.

  Therefore, the operator can easily determine whether the opening / closing body is currently locked or unlocked by looking at the direction indicated by the finger hook.

  That is, according to the second invention, the locked / unlocked state of the opening / closing body can be easily determined.

  In the second aspect of the present invention, the form and structure of the finger-hanging portion are arbitrary, and any shape may be used as long as it has directivity in a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member.

  As a first example of the finger-hanging portion in the second invention, an arrow shape or a substantially arrow shape indicating a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member can be cited. .

  In addition, the second example of the finger-hanging portion has an elongated shape that is long in a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member. One of the end portions may be a protruding shape. Here, the “protruding shape” includes a tapered shape, a sharp shape having an acute angle or an obtuse angle, a semicircular shape or a substantially semicircular shape.

  In the second example, the shape of the other end portion of the both ends in the longitudinal direction of the finger-hanging portion is arbitrary, and may be a recessed shape or may not be a recessed shape. Good.

  According to the former case, it becomes clearer that the shape of the finger-hanging portion has directivity in a direction orthogonal to or substantially orthogonal to the rotation axis direction of the rotation operation member. Therefore, it is more preferable that the shape of the other end of the both ends in the longitudinal direction of the finger-hanging portion is a depressed shape.

  In the first and second inventions described above, the locking device main body has the turning position of the finger-hanging portion at a position where the locking member is locked and / or detached from the locked member. It is preferable that an alignment portion for alignment is provided.

  According to this, the rotation position of the finger-hanging portion can be more accurately rotated to the position where the locking member is locked or detached from the locked member.

  Here, the alignment unit is located at a position in the lock device main body that is not hidden by the finger hooking portion even if the rotation operation member is rotated, in other words, at a position separated from the rotation range of the finger hooking portion in the lock device main body. Need to be provided.

  In addition, since there is “to adjust the rotation position of the finger-hanging portion to a position where the locking member is locked and / or disengaged from the locked member”, the positioning portion is It may be provided only for adjusting the rotation position of the locking portion to the position where the locking member is locked with respect to the locked member. It may be provided only for the position to be in the detached state, and for both of them, that is, in order to match the rotation position of the finger hanging portion to the position to be in the locking state, and the rotation of the finger hanging portion Two may be provided in order to match the position to the position in the disengaged state.

  In the second invention, the type and structure of the alignment portion are arbitrary, and the first example is a circular or substantially circular mark.

  A second example of the alignment unit is an arrow indicating the rotation center of the rotation operation member.

  A third example of the alignment unit is an open mark representing a character “open” or a close mark representing a character “close”.

  A fourth example of the alignment portion is the open mark and the close mark provided at symmetrical positions with respect to the rotation center portion of the rotation operation member.

  In addition, the mark, arrow, character, etc. used as the alignment part may be engraved on the lock device main body, and the label, mark, arrow, character, etc. having the shape of mark, arrow, character, etc. The label described may be affixed to the lock device body. In addition, a mark, an arrow, a character, or the like serving as an alignment unit may be provided so as to be recessed with respect to the lock device main body, or may be provided so as to protrude from the lock device main body. Furthermore, the mark portions such as marks, arrows, and characters that serve as alignment portions may be colored or uncolored.

  In the first and second inventions described above, the locking device main body may be provided with a cautionary note on which operational precautions are described.

  In addition, when the locking member is connected to the locked member via the connecting member, a cautionary note describing the operational precautions may be provided on the connecting member.

  The cautionary note may be engraved on the locking device main body or the connecting member, and a label on which the cautionary note is attached is attached to the locking device main body or the connecting member. Also good. Further, the notice may be colored or may not be colored.

  Furthermore, in the first and second inventions described above, the lock device main body may be provided with an arrow indicating the operation direction of the rotation operation member.

  This arrow may also be engraved on the lock device main body, or may be a label having the shape of an arrow, a label on which an arrow is written, affixed to the lock device main body, or the like. . Moreover, this arrow may be colored and does not need to be colored.

  In the above first and second inventions, an urging member for urging the movement of the lock member may be provided.

  According to this, the momentum of the lock member can be made the original momentum by the urging member, and thereby, the latching member can be locked and disengaged from the latched member as prescribed. Generation | occurrence | production of the semi-locking state of the locking member with respect to a member and a semi-detachment state can be eliminated.

  Here, the urging member may be an elastic member such as a spring or rubber, or may be a cylinder using fluid pressure such as air pressure, etc., as long as it can urge the movement of the lock member. Any biasing member may be used.

  When the biasing member is a spring, one end of the spring is connected to the lock device main body and the other end is connected to the lock member so that the movement of the lock member can be biased by the spring.

  This spring may be any kind of spring, one example of which is a coil spring, and the other example is a torsion spring in which a coil portion is provided between the one end and the other end. An example is a leaf spring.

  Further, when the urging member is a spring such as a coil spring or a torsion spring, at least one of the connection position of one end of the spring in the lock device main body and the connection position of the other end of the spring in the lock member is changed. It may be possible.

  According to this, since the magnitude of the spring force can be changed by changing at least one of the connection position of one end of the spring in the lock device main body and the connection position of the other end of the spring in the lock member, The magnitude of the biasing force applied to the member can be adjusted.

  In addition, what connects the one end and other end of a spring may be protrusion members, such as a pin, and a protrusion part, and hollow parts, such as a hole and a recessed part, may be sufficient as it.

  In the first and second aspects of the invention, the urging member that urges the movement of the locking member of the locking device includes the movement of the locking member for locking the locking member to the locked member, and the locking member. Among the movements of the lock member for releasing the locking member from the locked member, at least when the movement of the locking member for releasing the locking member from the locked member is urged, The locking device provides resistance to the movement of the rotation operation member near the end of the movement of the locking member for locking the locking member to the locked member, and the locking member is detached from the locked member. There may be provided a resistance applying mechanism that does not apply resistance to the movement of the rotation operation member near the end of the movement of the lock member.

  According to this, even if the urging member that urges the movement of the locking member of the locking device urges the movement of the locking member for detaching at least the locking member from the locked member, The resistance force applying mechanism does not apply a resistance force to the movement of the rotary operation member near the end of the movement of the locking member for detaching the locking member from the locked member, so that the locking member is detached from the locked member. Therefore, the movement of the lock member can be effectively performed using the urging force of the urging member as it is. Further, the resistance force applying mechanism applies a resistance force to the movement of the rotation operation member near the end of the movement of the locking member for locking the locking member to the locked member. The movement of the lock member for engaging with the stop member can be performed by operating the rotation operation member that creates a sense of moderation.

  The specific structure of the resistance-applying mechanism having such an action is arbitrary, and an example thereof is that at least one of the rotation operation member and the lock device main body is provided with a convex portion protruding toward the other. That is.

  In the locking device for the opening / closing device according to the first and second inventions described above, the locking member and the locking member may or may not be connected.

  When the locking member and the locking member are connected, the locking member is switched between locking and detachment with respect to the locked member by the movement of the locking member with respect to the locking device main body.

  In this way, when the locking member and the lock member are connected to each other, the movement form and the engagement of the lock member can be switched so that the locking member can be switched between the locking member and the locking member. The form of the movement of the stop member may be arbitrary, and an example thereof is to make these movements forward and backward.

  Further, in an example in which the locking member and the lock member are not connected, the movement of the locking member is turned, and the movement of the lock member with respect to the lock device main body is moved forward and backward. The rotation preventing member that prevents the rotation of the locking member is connected. The locking member that is prevented from rotating by the rotation blocking member is locked to the locking to the locked member, and is rotated by the lock member. When the blocking member moves backward, the locking member can be turned and can be detached from the locked member.

  Further, in another example in which the locking member and the locking member are not coupled, the opening / closing body is provided with a handle member for placing a hand to move the opening / closing body, and the locking member is attached to the locking member. In order to be able to be locked and disengaged with respect to the locked member, the opening / closing body is arranged so as to be movable, and the handle member is moved by the movement of the lock device main body and the lock member approaching the handle member is It is to make the moving operation impossible.

  In this case, the handle member and the locking member may be connected or may not be connected.

  When the handle member and the locking member are connected, the locking member is switched between locking and releasing with respect to the locked member by moving the handle member.

  In addition, in a case where the handle member and the locking member are not connected, in order to switch the locking member to locking and detachment with respect to the locked member, for example, the movement of the locking member is performed. The rotation operation is a forward / backward movement operation of the handle member, and a rotation blocking member for blocking the rotation of the locking member is connected to the handle member, and the rotation blocking member prevents the rotation. The blocked locking member is locked by the locking to the locked member, and the rotation blocking member moves backward by the handle member so that the locking member can be rotated and detached from the locked member. To be.

  Furthermore, when the locking device according to the first and second inventions is applied to a shutter device that winds and stores a shutter curtain with a winding shaft, the structure and type of the winding shaft are arbitrary. That is, the take-up shaft may be formed by connecting one shaft or a plurality of shafts in series, and for winding and feeding the shutter curtain around the outer periphery of the fixed shaft arranged at the center. The rotating member may be rotatably arranged. In the latter case, the rotating member includes a plurality of wheels rotatably fitted on the outer periphery of the fixed shaft and a bar-shaped connection that connects these wheels spaced apart in the axial direction of the fixed shaft. It may be formed including a member, or may be formed including these wheels and a pipe-shaped member that is fixedly fitted to the outer periphery of these wheels to couple the wheels together.

  The shutter curtain including the seat plate may be formed entirely or substantially entirely by slats, may be formed by a panel, may be formed by a sheet, and is formed by a pipe connected by a link. Or may be formed of a net, or a composite of a plurality of different types of members, for example, a composite of a plurality of these, such as a slat and a pipe. Good.

As shown in FIG. 3, the locking member 21 according to the present embodiment has a rake shape in which three convex portions 21 </ b> B are formed at the distal end portion on the guide rail 4 side. As shown in FIG. 5 and FIG. 5, the locked member 22 is formed with two rising wall portions 22A on both sides in the thickness direction of the shutter curtain 1, and each of these rising wall portions 22A has As shown in FIG. 3, three recesses 22B are provided.

  As described above, when the locking member 21 moves forward to the guide rail 4 side while riding on the raised portion 17B formed on the base member 17, as shown in FIG. The protrusion 21B is inserted into the three recesses 22B of the locked member 22, whereby the locking member 21 is locked to the locked member 22 and reaches the fully closed position in FIG. Is locked. As shown in FIG. 4, when the locking member 21 moves backward, the locking member 21 is detached from the locked member 22, and the shutter curtain 1 is unlocked.

  Note that the forward movement of the locking member 21 toward the guide rail 4 is performed by compressing the coil spring 19 as described above. Therefore, the engagement member 21 is engaged by a large elastic pressure due to the compression spring force of the coil spring 19. The stop member 21 can be strongly pressed against the locked member 22.

  Further, since the three recessed portions 22B of the locked member 22 are formed on the rising wall portions 22A formed on both sides in the thickness direction of the shutter curtain 1, as shown in FIG. Even if the standing position of the two guide rails 4 is reversed left and right, the locking member 21 can be locked to the locked member 22.

  FIG. 6 shows the internal structure of the locking device 11 shown in FIGS. 1 and 2. A pinion member 23 is rotatably disposed inside the lock device main body 11A. As shown in FIG. 2, a thumb turn member 24 serving as a turning operation member that is turned by a finger is provided on the back surface of the lock device main body 11A. Both a plate key (not shown) inserted into the keyhole 11B of the lock device 11 shown in FIG. 1 and operated to rotate with a finger and the thumb turn member 24 shown in FIG. 2 are not shown. It is connected with the pinion member 23 via connecting members, such as a cylinder, and the range in which these plate keys and the thumb turn member 24 can be rotated is 180 degrees.

  When either the plate key or the thumb turn member 24 is rotated 180 degrees in one direction, the pinion member 23 is also rotated 180 degrees in the same direction via the connecting member such as the cylinder. Is rotated 180 degrees in the other direction, the pinion member 23 is also rotated 180 degrees in the same direction via the connecting member such as the cylinder. As shown in FIG. 6, the pinion member 23 is formed with a plurality of teeth 23 </ b> A, and each lock member 12 of the lock device 11 is formed with a plurality of teeth 12 </ b> A that mesh with these teeth 23 </ b> A. Therefore, when either of the above is rotated 180 degrees in one direction, the lock member 12 moves forward with respect to the lock device main body 11A as shown in FIGS. As described above, the locking member 21 is also moved forward to be locked to the locked member 22, and the shutter curtain 1 reaching the fully closed position is locked. Further, when either of the above is rotated 180 degrees in the other direction, the lock member 12 moves backward with respect to the lock device main body 11A as shown in FIGS. The stop member 21 also moves backward to be disengaged from the locked member 22, and the shutter curtain 1 is unlocked. Thereafter, the shutter member 21 is put on the handle member 10 shown in FIG. The curtain 1 can be opened and moved.

  When the shutter curtain 1 is unlocked by the rotation operation of the plate key, the direction of the plate key at this time is vertical, and therefore the opening movement operation of the shutter curtain 1 is performed by the plate key. Even in this case, it is possible to prevent breakage of the plate key whose strength is increased in the opening movement direction.

  As can be seen from the above, the locking and disengaging of the locking member 21 with respect to the locked member 22 is selected by the forward and backward movement of the locking member 12 of the locking device 11, and the locking and unlocking of the shutter curtain 1 are selected. Is done. That is, when the locking member 12 of the locking device 11 moves forward and backward, the locking and unlocking of the locking member with respect to the locked member 22 is switched, and thereby the locking and unlocking of the shutter curtain 1 are switched.

  In addition, when the force which rotates the pinion member 23 is input to the pinion member 23 from the lock member 12 side, the pinion is determined by the shape setting of the aforementioned tooth portions 12A and 23A of the lock member 12 and the pinion member 23. The member 23 does not rotate. Therefore, when the lock member 12 reaches the reverse position shown in FIG. 6, the locking member 21 is detached from the locked member 22 unless the above-described plate key or thumb turn member 24 is operated. When the lock member 12 has reached the advanced position shown in FIG. 7, the locking member 21 is locked to the locked member 22 unless the plate key or the thumb turn member 24 is operated. Locked to state.

  Further, when an unauthorized plate key is used as the above-described plate key, the unauthorized plate key can be inserted into the key hole 11B of the lock device 11 described above, but via the connecting member such as the cylinder described above. Thus, the pinion member 23 cannot be rotated.

  As shown in FIGS. 6 and 7, the lock device 11 is provided with a spring serving as an urging member for moving the lock member 12 backward. This spring according to the embodiment of FIGS. 6 and 7 is a coil spring 25. One end 25 </ b> A of the coil spring 25 is connected to a pin 26 provided on the lock device main body 11 </ b> A, and the other end 25 </ b> B is connected to a pin 27 provided on the lock member 12. Therefore, the coil spring 25 is installed between the lock device main body 11 </ b> A and the lock member 12.

  Therefore, when the lock member 12 moves from the reverse position in FIG. 6 to the forward position in FIG. 7, a tensile force is generated in the coil spring 25. Therefore, when the lock member 12 is moved backward by the rotation operation of the plate key or the thumb turn member 24 described above, the backward movement of the lock member 12 is biased by the tensile force of the coil spring 25. Then, the lock member 12 reaches the reverse drive position in FIG.

  Therefore, when the lock member 12 is moved backward by the rotation operation of the plate key or the rotation operation of the thumb turn member 24 in order to unlock the shutter curtain 1 that has reached the fully closed position, for example, the plate Even if the key turning operation or the turning operation amount of the thumb-turn member 24 is insufficient, the lock member 12 moves by the original reverse movement amount. Therefore, the locking member 21 is not in a semi-detached state with respect to the locked member 22, and the shutter curtain 1 is not in a semi-unlocked state. Therefore, the opening movement of the shutter curtain 1 by the handle member 10 is prevented. This can be performed as prescribed without applying an excessive load to 21 or the locked member 22.

  8 and 9, the coil portion 35C is provided between the one end 35A and the other end 35B with a spring installed between the lock device main body 11A and the lock member 12 in order to bias the movement of the lock member 12. An embodiment in which a torsion spring 35 is provided is shown. One end 35 </ b> A of the torsion spring 35 is connected to a pin 36 provided on the lock device main body 11 </ b> A, and the other end 35 </ b> B is connected to a pin 37 provided on the lock member 12. Further, the coil portion 35C is in a floating state that is not fixed to both the lock device main body 11A and the lock member 12.

  When the lock member 12 moves backward as shown in FIG. 8 by rotating the plate key or the thumb turn member 24, the backward movement force F1 acts on the lock member 12 by the spring force of the other end 35B of the torsion spring 35. ing. Further, when the lock member 12 moves forward as shown in FIG. 9, a force F <b> 2 is applied to the lock member 12 by the spring force of the other end 35 </ b> B of the torsion spring 35. Since this force F2 has an inclination component toward the forward movement direction of the lock member 12, the forward movement force F2A due to this component acts on the lock member 12.

  In other words, when the lock member 12 is moved forward and backward by the above-described rotation operation of the plate key or the rotation operation of the thumb turn member 24, the backward movement force F1 and the forward movement force are in the middle of the forward and backward movement path. There is a dead point at which F2A becomes zero, and when the lock member 12 moves backward beyond the dead point, the backward movement is urged by the backward movement force F1, and the lock member 12 moves forward beyond the dead point. Then, this forward movement is urged by the forward movement force F2A. The state of the torsion spring 35 in FIG. 9 that moves the lock member 12 forward by the urging force is the first torsion state, and the state of the torsion spring 35 in FIG. 8 that moves the lock member 12 backward by the urging force is the first state. The torsion spring 35 can be freely changed between the first torsion state and the second torsion state.

  For this reason, according to this embodiment, both the backward movement and the forward movement of the lock member 12 can be urged by the torsion spring 35, and therefore the locked member 12 can be energized regardless of whether the lock member 12 is moved forward or backward. The locking member 21 is not in a semi-locked state or a semi-detached state with respect to the locking member 22, and the shutter curtain 1 can be prevented from being in a semi-locked state or a semi-unlocked state.

  8 and 9, a buffer member 38 made of rubber, soft synthetic resin, or the like is attached to the end of each lock member 12 inserted into the lock device body 11A. These buffer members 38 come into contact with the lock device main body 11 </ b> A in the backward movement limit of the lock member 12. For this reason, even if the lock member 12 moves backward to the backward movement limit by a large force due to the urging force of the torsion spring 35, the lock member 12 does not directly contact the lock device main body 11A, and the lock member 12 or the lock device main body 11A. Can prevent damage.

  The buffer member 38 may be attached to the lock device main body 11A, or may be attached to both the lock device main body 11A and the lock member 12.

  Such a buffer member 38 can also be applied to the embodiment of FIGS. 6 and 8 in which the biasing member is the coil spring 25.

  10 and 11, in order to connect the other end 35B of the torsion spring 35 to the lock member 12, a plurality of pins 37A, 37B, and 37C are provided on the lock member 12 in the illustrated example. . These pins 37A, 37B, 37C are arranged in parallel in the forward / backward movement direction of the lock member 12, and the other end 35B of the torsion spring 35 is connected to one of these pins 37A, 37B, 37C. Since it can selectively connect, the connection position of the other end 35B in the lock member 12 can be changed. By making this change, it is possible to adjust the magnitude of the spring force of the torsion spring 35 that acts as a biasing force on the lock member 12.

  In order to make it possible to adjust the spring force of the torsion spring 35 in this way, the number of pins provided on the lock device main body 11A for connecting the one end 35A of the torsion spring 35 is the same as that of the pins 37A, 37B, and 37C. In addition, a plurality of lock members 12 may be arranged in parallel in the forward / backward movement direction of the lock member 12 or in a direction inclined with respect to the forward / backward movement direction.

  Further, in order to adjust the spring force of the torsion spring 35 in this way, providing a plurality of pins on the lock member 12 and / or the lock device main body 11A is that the biasing member is a coil spring 25. FIG. It can also be applied to the embodiment of FIG.

  Furthermore, in order to be able to adjust the spring force of the torsion spring 35 or the coil spring 25, when a plurality of pins are provided on the lock member 12 and / or the lock device main body 11 </ b> A, these pins are connected to the front and rear of the lock member 12. You may arrange in parallel in the direction orthogonal to the advancing movement direction. According to this, when the biasing member for biasing the movement of the lock member 12 is a torsion spring 35, the dead point is generated when the spring force of the torsion spring 35 is adjusted. It is possible to prevent the rotation position of the key or thumb turn member 24 from changing.

  Further, when the urging member for urging the movement of the lock member 12 is the torsion spring 35, the dead point occurs when the plate key or the thumb turn member 24 is rotated 90 degrees from the initial position. Thus, it is preferable to set the arrangement state of the torsion spring 35 in the lock device 11.

  Further, the torsion spring 35 or the coil spring 25 for biasing the movement of the lock member 12 may be installed between the two lock members 12.

  FIG. 12 shows the back surface of the lock device main body 11A on which the thumb turn member 24, which is a turning operation member operated by a finger, is arranged. Therefore, FIG. 12 is the reverse of FIGS. 6 to 11.

  The thumb turn member 24 has a finger hook portion 24A (a specific shape and structure will be described later) for hooking a finger that turns the thumb turn member 24. The finger hook portion 24A is used to turn the thumb turn member 24. It has a long and narrow shape in a direction perpendicular to or substantially perpendicular to the axial direction (thickness direction of the shutter curtain 1). In other words, the finger hook portion 24A is used when the lock member 12 has reached the backward movement limit (when shown in FIG. 12) and when the lock member 12 has reached the forward movement limit (when shown in FIG. 13). The elongated shape is long in the left-right direction, which is the width direction of the shutter curtain 1. Then, the thumb turn member 24 is rotated 180 degrees as described above in order to rotate the pinion member 23 shown in FIG. 6 and the like around the central axis provided in the longitudinal center of the finger hook 24A. It is free to rotate.

  As shown in FIGS. 12 and 13, the lock device main body 11 </ b> A is provided with two arrows 61 and 62 indicating the rotation operation direction of the thumb-turn member 24, and the arrow 61 is counterclockwise. The arrow 62 indicates the clockwise direction. When the thumb turn member 24 is turned 180 degrees in the direction of the arrow 61 (in other words, counterclockwise) as shown in FIG. 12 by putting a finger on the finger hook portion 24A, the lock member 12 moves forward to move the locking member 21. Is locked to the locked member 22, and the shutter curtain 1 is locked. Thereafter, when the thumb turn member 24 is rotated 180 degrees in the direction of the arrow 62 (in other words, clockwise) as shown in FIG. 13, the lock member 12 moves backward, and the locking member 21 is locked. The shutter curtain 1 is unlocked.

  As shown in FIGS. 12 and 13, when the shutter curtain 1 is locked and unlocked, the lock member main body 11 </ b> A is opposed to both longitudinal ends of the finger hook portion 24 </ b> A of the thumb-turn member 24. The convex part 41 is formed. This convex portion 41 is shown in FIG. 14, which is a cross-sectional view taken along the line S14-S14 in FIG. 12, and a part of the lock device body 11A formed of sheet metal is extruded into a semispherical shape or a substantially hemispherical shape. By doing so, the lock device main body 11A is provided.

  Concave portions 42 for accommodating the convex portions 41 are formed at both ends in the longitudinal direction of the finger hook portion 24A of the thumb turn member 24 facing the convex portions 41 when the shutter curtain 1 is locked and unlocked. In addition, grooves 43 reaching the outer edge of the thumb turn member 24 from the recess 42 are formed at both longitudinal ends of the thumb turn member 24. These grooves 43 are formed continuously at the locus-like portions of the thumb turn member 24 that sequentially face the convex portions 41 when the thumb turn member 24 is rotated as indicated by an arrow 61.

  Then, at least the peripheral part of the concave part 42 and the groove 43, that is, in the embodiment of FIG. 14, all the parts facing the locking device main body 11A of the finger hooking part 24A of the thumb turn member 24 excluding the concave part 42 and the groove 43 are A protrusion 44 (see FIG. 14) protrudes from the recess 42 and the groove 43 toward the lock device main body 11A. The protrusion 44 protrudes from the protrusion 41 and the protrusion 44 of the lock device main body 11A. Is a size that can be contacted.

  In order to lock the shutter curtain 1 by locking the locking member 21 to the locked member 22, the state shown in FIG. 12 (in FIG. 12, the specific structure provided in the finger hooking portion 24A will be described later. 12 shows a state in which the shutter curtain 1 is unlocked because the 60 is horizontally oriented leftward.) The thumb turn member 24 that has been unlocked 180 degrees in the direction of the arrow 61 in FIG. When rotated, the thumb turn member 24 rotates with respect to the lock device main body 11A while the concave portion 42 and the groove 43 pass through the convex portion 41, and near the end of the rotation of 180 degrees. The protruding portion 44 provided at least in the peripheral portion of 42 abuts on the convex portion 41. For this reason, the rotation of the thumb turn member 24 by 180 degrees is such that the finger hook portion 24A of the thumb turn member 24 formed of an elastically deformable material such as a synthetic resin or rubber is elastically deformed, and the protruding portion 44 causes the protruding portion 41 to move. The protrusion 41 enters the inside of the recess 42 of the finger hook 24 </ b> A of the thumb turn member 24. This state is shown in FIG.

  In FIG. 13, since the arrow 60 provided on the finger hanging portion 24 </ b> A is oriented horizontally to the right, the shutter curtain 1 is locked by the locking member 21 and the locked member 22. .

  In order to release the locking member 21 from the locked member 22 and unlock the shutter curtain 1, the thumb turn member 24 in the state of FIG. 13 is rotated 180 degrees in the direction of the arrow 62 in FIG. In this case, first, the thumb turn member 24 rotates while the protruding portion 44 of the thumb turn member 24 rides on the convex portion 41 of the lock device main body 11A due to the elastic deformation of the thumb turn member 24. Near the end of rotation, after the groove 43 of the thumb turn member 24 passes through the convex portion 41, the convex portion 41 enters the concave portion 42 of the thumb turn member 24.

  From the above, in order to release the locking member 21 from the locked member 22 and unlock the shutter curtain 1, the thumb turn member 24 in the state of FIG. 13 is moved in the direction of the arrow 62 in FIG. When the thumb turn member 24 is rotated 180 degrees, a resistance force is generated when the protrusion 44 of the thumb turn member 24 comes into contact with the protrusion 41 of the lock device main body 11A and rides on the protrusion 41, and resists this resistance. The operator of the thumb turn member 24 rotates the thumb turn member 24. Near the end of 180-degree rotation, the groove 43 of the thumb-turn member 24 passes through the convex portion 41, and the convex portion 41 smoothly enters the concave portion 42 of the thumb-turn member 24. Then, the resistance force does not occur.

  For this reason, in this embodiment, the resistance for applying a resistance force to the rotation operation of the thumb turn member 24 by the convex portion 41 of the lock device main body 11A and the concave portion 42, the groove 43, and the protruding portion 44 of the thumb turn member 24. A force applying mechanism 45 (see FIG. 14) is configured, and this resistance applying mechanism 45 is located near the end of the forward movement of the lock member 12 for locking the locking member 21 to the locked member 22. Immediately after starting the backward movement of the locking member 12 for releasing the locking member 21 from the locked member 22 after the forward movement, a resistance force is applied to the rotation operation of the thumb-turn member 24, and the locking member 21 is engaged. Near the end of the backward movement of the locking member 12 for releasing the locking member 22 and immediately after the forward movement of the locking member 12 for locking the locking member 21 to the locked member 22 after the backward movement. Te, which is assumed not to confer resistance to the rotational operation of the thumb-turn member 24.

  Therefore, as described above, the coil for energizing the backward movement of the lock member 12 for detaching at least the locking member 21 from the locked member 22 between the lock device main body 11A and the locking member 12. Even if the spring 25 or the torsion spring 35 is installed, the resistance applying mechanism 45 is provided near the end of the reverse movement of the lock member 12 for releasing the locking member 21 from the locked member 22. Since no resistance force is applied to the turning operation, the backward movement of the lock member 12 for detaching the locking member 21 from the locked member 22 is used as it is by using the spring force of the coil spring 25 or the torsion spring 35. It can be made effective. In addition, the resistance applying mechanism 45 provides resistance to the turning operation of the thumb turn member 24 near the end of the forward movement of the lock member 12 for locking the locking member 21 to the locked member 22. The forward movement of the locking member 12 for locking the locking member 21 to the locked member 22 can be performed by the rotation operation of the thumb turn member 24 where a sense of moderation occurs.

  Further, after the lock member 12 reaches the forward movement limit, when the thumb turn member 24 is rotated in the direction in which the lock member 12 is moved backward, a resistance force is generated by the resistance force applying mechanism 45. It is possible to prevent the thumb turn member 24 from being rotated inadvertently or accidentally in the direction in which the member 12 is moved backward.

  FIGS. 15-19 shows another embodiment about the locking member which locks and unlocks the shutter curtain 1, and a to-be-latched member.

  The locking member 121 according to this embodiment shown in FIG. 15 is a cast product made of an alloy, for example, and has a triangular tongue-shaped locking portion 121A that locks to the locked member 122 shown in FIG. As shown in FIG. 16, it has a contact portion 121B provided on the inner side in the width direction of the shutter curtain 1 than the locking portion 121A. Further, as shown in FIG. 16, two locking members 121 are formed on a base member 117 fixed to a slat 9B forming the shutter curtain 1 by a fixing tool 116 such as a rivet. A pin 70 installed between the portions 117A is pivotable in the vertical direction. A coil spring 71 is wound around the pin 70, and one end 71A of the coil spring 71 is formed on the base member 117. The other end 71 </ b> B is inserted into a hole 121 </ b> C formed in the locking member 121. For this reason, the locking member 121 is moved by the coil spring 71 to a rotation position where the extending direction of the triangular tongue-shaped locking portion 121A is horizontal or substantially horizontal as shown in FIG. The pin 70 is always elastically biased around the center.

  As shown in FIGS. 17 and 18 which are cross-sectional views taken along line S17-S17 in FIG. 16, a slide member 118 is movably disposed on the base member 117, and the slide member 118 is also shown in FIG. As shown in FIG. 5, the guide member 117C formed above and below the slide member 118 by bending a part of the base member 117 on the base member 117 on the inner side in the width direction of the shutter curtain 1 with respect to the locking member 121. The slide member 118 is arranged in between and guided by the guide portions 117 </ b> C so as to be movable in the width direction of the shutter curtain 1. As can be seen from FIGS. 17 and 18, the slide member 118 is a folded product of a plate material, and includes a first portion 111 on the outer side in the width direction of the shutter curtain 1 and a second portion 112 on the inner side in the width direction.

  The second portion 112 is formed with a spring hook portion 112A. The spring hook portion 112A is formed in the base member 117 and protrudes from the long hole 112B of the second portion 112 to the slide member 118 side. Are opposed to each other in the width direction of the shutter curtain 1, and both end portions of the coil spring 113 serving as a tension spring are hooked on the spring hook portions 112A and 117D. For this reason, the slide member 118 is always elastically pulled outward in the width direction of the shutter curtain 1 with respect to the base member 117.

  As shown in FIG. 15, also in this embodiment, the locking device 11 described with reference to FIGS. 2 and 12, etc. is used, and this locking device 11 is arranged on the slat 9B. A connecting portion 115 of the slide member 118 of FIG. 16 is connected to the pair of left and right lock members 12 of the locking device 11 via a connecting member 114. For this reason, the lock member 12 and the slide member 118 are connected via the connecting member 114.

  The normal state of the lock device 11 in this embodiment is a state in which each lock member 12 is moved forward from the lock device main body 11A. FIG. 17 shows the state of the slide member 118 at this time. At this time, the first portion 111 of the slide member 118 reaches the lower position of the contact portion 121B of the locking member 121 by the pulling force of the coil spring 113. For this reason, as shown in FIG. 19, the locking member 121 in which the extending direction of the triangular tongue-shaped locking portion 121 </ b> A is a horizontal direction or a substantially horizontal direction is lower than the pin 70. Is prevented by the contact portion 121 </ b> B coming into contact with the first portion 111 of the slide member 118.

  As shown in FIG. 17, the surface 111 </ b> A that faces the contact portion 121 </ b> B of the locking member 121 in the first portion 111 of the slide member 118 moves toward the outer side in the width direction of the shutter curtain 1. The surface 121D of the contact portion 121B facing the surface 111A is also the same as the surface 111A. Therefore, the slide movement of the slide member 118 when the first portion 111 of the slide member 118 reaches the lower position of the contact portion 121B of the locking member 121, and the first portion 111 of the slide member 118 contacts the locking member 121. The slide movement of the slide member 118 that comes out from the lower position of the contact portion 121B is performed smoothly.

  FIG. 19 shows a locked member 122 that is a member for locking the shutter curtain 1 together with the locking member 121. The locked member 122 is attached to the inside of the guide rail 4, and the upper surface 122A of the locked member 122 is an inclined surface that is inclined downward from the outside to the inside of the guide rail 4, The lower surface 122B is a horizontal plane or a substantially horizontal plane. Further, the upper surface 121E of the locking portion 121A of the locking member 121 is horizontal or substantially horizontal, and the lower surface 121F is directed from the outer side to the inner side of the guide rail 4 like the upper surface 122A of the locked member 122. The slope is inclined downward.

  When the shutter curtain 1 that has reached the fully open position is lowered and the locking portion 121A of the locking member 121 that is rotatably disposed on the shutter curtain 1 contacts the locked member 122 from above, the locking is performed. Due to the action of the inclined lower surface 121F of the portion 121A and the inclined upper surface 122A of the locked member 122, the locking member 121 is configured so that the locking portion 121A is in the state of the two-dot chain line 121A ′. The locking member 121 passes through the locked member 122 and the shutter curtain 1 reaches the fully closed position shown in FIG. Then, when the locking member 121 returns and rotates downward by the spring force of the coil spring 71, the locking portion 121A returns to the horizontal state or the substantially horizontal state indicated by the solid line in FIG. 19, and the locking portion 121A. The upper surface 121 </ b> E faces the lower surface 122 </ b> B of the locked member 122.

  Thereafter, in order to open and move the shutter curtain 1, even if a hand is put on the handle member 10 of FIG. 1 that is fixedly arranged on the shutter curtain 1 and the shutter curtain 1 is lifted as it is, the locked member 122.

Therefore, it cannot rotate downward. In other words, the locking member 121 is locked with respect to the locked member 122. Therefore, at this time, the shutter curtain 1 is in a locked state in which the opening movement with respect to the guide rail 4 is restricted, and from the fully opened position. As soon as the locking member 121 of the shutter curtain 1 that has been closed and moved downward passes through the locked member 122 of the guide rail 4, the shutter curtain 1 is automatically locked in the fully closed position.

  For this reason, the slide member 118 in this embodiment is a rotation blocking member for blocking the rotation of the locking member 121 in order to lock the shutter curtain 1 that has reached the fully closed position. The locking member 121 is locked in a locked state with respect to the locked member 122 by the rotation preventing member.

  In order to open and move the shutter curtain 1 from the fully closed position, the lock member 12 of the lock device 11 is moved backward by the rotation operation of the plate key or the thumb turn member 24. Accordingly, the connecting member 114 shown in FIGS. 15 and 16 also moves backward, and the first portion 111 of the slide member 118 that has also moved backward moves away from the contact portion 121B of the locking member 121. When the shutter curtain 1 is lifted by a hand hung on the handle member 10 while maintaining this state, the locking member 121 in which the upper surface 121E of the locking portion 121A contacts the lower surface 122B of the locked member 122 is locked. The locking member 121 pivots downward about the pin 70 until the portion 121A reaches the state of the two-dot chain line 121A ″ in FIG. Will pass. In other words, at this time, the locking member 121 is detached from the locked member 122, and the shutter curtain 1 is unlocked, so that the shutter curtain 1 can be opened and moved.
