JP 2002-180755 A

  If the crescent is not in a closed state, the hook does not engage with the receiving portion. Therefore, even when the handle is rotated, the crescent is not locked and locked. As described above, the crescent that is also in the hanging state is not preferable in terms of crime prevention because it may not be locked even if the handle is rotated. In addition, when the shoji is run in an empty state, the nail-like hook may damage or deform the shoji's heel. Therefore, the applicant of the present invention provides the crescent box portion with a trigger portion that protrudes to the outside of the room as the handle rotates, and the hook portion has a protrusion portion that protrudes toward the indoor side. When the handle is rotated with the shoji screen closed, the handle comes into contact with the projection on the hook side, and when the trigger comes into contact with the projection, the handle is unlocked, and the trigger further protrudes without coming into contact with the projection. Then, the crescent which provided the rotation prevention mechanism which locks a handle was invented.

  Here, when the crescent is in a locked state, an auxiliary lock is used that prevents the handle from rotating and increases the security. The operation of the auxiliary lock is performed independently of the operation of the handle. That is, when locking the crescent, the handle is first rotated to engage the hook with the receiving portion, and then the auxiliary lock is slid to lock the rotation of the handle.

  However, with such an auxiliary lock, two operations are required to lock the handle, so the operation may be forgotten, and crime prevention may not be sufficiently secured. In addition, the crescent having the function of preventing the above-mentioned hanging state recognizes that the handle is rotated and the locking is surely performed, and forgets to operate the auxiliary lock which is the second operation. There was also a tendency to become apt.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a crescent that automatically locks when locked by a handle operation.

In order to solve the above-mentioned problems, a crescent according to the present invention is provided in a summoning lance of the inner and outer shojis provided in the frame, and includes a hanging portion that rotates in conjunction with a handle and the hanging portion. And a crescent that is detachable from a receiving portion provided on the summoning jar of the external shoji.
The crescent box portion is provided with a rotating body that rotates as the handle rotates, and an operating body that is exposed to the outer surface and is slidable between the first position and the second position. The operating body is urged by the elastic body in the direction from the second position toward the first position, and is formed on the rotating body when the handle is rotated to the locking position. A rotation blocking portion for blocking rotation adjacent to the contact portion, and an engagement portion formed on the rotating body when in the second position so as to be attached by the elastic body. An engaging portion that counteracts the force,
When the handle is rotated in the unlocking direction with the engaging part of the operating body engaged with the engaged part of the rotating body , the engaging part is engaged with the engaged part. together but is released, the said operating member by the rotating body is held in the second position side against the urging by the elastic member, when rotating the handle from the unlocking position side to the locked position, The operating body is released from being held by the rotating body and moved to the first position by the urging force of the elastic body, and the rotation blocking portion is adjacent to the contact portion.

  In the crescent according to the present invention, the crescent box portion is provided with a rotation prevention mechanism, and the rotation prevention mechanism is capable of projecting from the box portion to the outdoor side as the rotating body rotates. And the trigger part rotates the handle when it protrudes to the outside of the room from the protruding part formed to protrude to the indoor side in the summon of the hand-operated child as the handle rotates. It is configured to be locked.

  Further, in the crescent according to the present invention, the rotation preventing portion of the operation portion has a planar contact surface facing the outdoor side inside the box portion, and the rotating body is formed in a substantially disc shape. And a projecting portion projecting in a radial direction, wherein one side surface of the projecting portion is in contact with the contact surface when the hook portion is in the first position when the hook portion is engaged with the receiving portion. The contact portion is configured as a feature.

  According to the crescent according to the present invention, the crescent box portion is provided with the rotating body and the operating body, and the operating body includes the rotation blocking portion and the engaging portion, and the first position from the second position by the elastic body. When the handle is rotated with the engaging portion of the operating body engaged with the rotating body, the engaging state of the engaging portion is released and the operating body is moved to the second position by the rotating body. When the handle is rotated to the locked position, the operating body is released from being held by the rotating body and moved to the first position by the urging of the elastic body, and the rotation preventing portion is moved to the contact portion. By being adjacent to each other, an auxiliary lock can be automatically made when the handle is locked. Further, when unlocking by a handle operation, it is necessary to manually release the auxiliary lock so that the operating body is engaged with the rotating body, so that the crime prevention property can be sufficiently secured.

  Further, according to the crescent according to the present invention, the crescent box portion is provided with a rotation prevention mechanism, and the rotation prevention mechanism has a trigger portion that can protrude from the box portion to the outdoor side as the rotating body rotates. The trigger part is operated by locking the turning of the handle when it protrudes from the protrusion formed so as to protrude to the indoor side of the shoji summon as the handle rotates. By using a rotating body that locks the body, it is possible to configure a rotation blocking mechanism that prevents emptying.

  Further, according to the crescent according to the present invention, the rotation preventing portion of the operation portion has a flat contact surface facing the outdoor side inside the box portion, and the rotating body is formed in a substantially disc shape. And a projecting portion that protrudes in the radial direction, and one side surface of the projecting portion is a contact portion that contacts the contact surface when the hook portion is in the first position with the receiving portion engaged. As a result, the contact portion can be reliably brought into contact with the rotation prevention portion in accordance with the handle operation.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of a sash according to this embodiment as viewed from the indoor side. As shown in this figure, the sash in this embodiment is provided with a rectangular frame 1 at the opening of a building, and two shojis 4 and 4 are housed in a sliding manner.

  The shoji 4 is obtained by placing the glass body 3 in a casing 2 formed by assembling an upper rod 40, a lower rod 41, and left and right vertical rods 42, 42 into a square shape. Then, the crescent 10 is provided on the summon 43 of the inner shoji 4a, and the receiving bracket 15 is provided on the summon 43 of the outer shoji 4b.

  The crescent 10 includes a box part 11 fixed to the summoning basket 43, a handle 13 rotatably attached to the box part 11, and a claw-like hook part 12 fixed to the handle 13 and rotating together. ing. The receiving bracket 15 includes a receiving portion 16 that is engaged when the hanging portion 12 of the crescent 10 is rotated in a state in which the inner and outer obstacles 4a and 4b are closed.

  In FIG. 2, the front view which looked at the crescent 10 from the outdoor side is shown. As shown in this figure, the box portion 11 is formed in a box shape that is long in the vertical direction, and the handle 13 is provided so as to be rotatable adjacent to the box portion 11. The hanging portion 12 is attached to a surface that becomes an outdoor surface when the handle 13 is disposed upward.

  Inside the box part 11, a turning mechanism for turning the handle 13 and a turning restricting mechanism 20 for locking the turning of the handle 13 when the hanging part 12 is in the hung state are housed. As shown in FIG. 2, two openings 11 a are provided on the outdoor surface of the box portion 11 for the trigger portion 23, which is a part of the rotation restricting mechanism 20, to protrude as the handle 13 rotates. It has been. In this embodiment, the trigger part 23 protrudes from the upper opening part 11a. Details of the rotation restricting mechanism 20 will be described later.

  In FIG. 3, the front view which looked at the metal fitting 15 from the room inner side is shown. 3, the right half shown in FIG. 3 is formed as a fixing portion 17 for the summing rod 43, and the left half is formed as a receiving portion 16 for the hanging portion 12 of the crescent 10. The receiving portion 16 is formed in a frame shape having a square shape and a hollow central portion, and has an engaged portion 16 a that engages with the hanging portion 12 of the crescent 10 at the left end portion. A metal cover 30 made of a resin material is provided on the interior surface of the receiving portion 16.

  The metal cover 30 is formed in a frame shape having a hollow center part so as to substantially cover the receiving part 16. However, the engaged portion 16a is exposed to the indoor side. Further, the metal fitting cover 30 is formed with a protruding portion 31 that protrudes in a substantially L shape from the upper portion thereof to the side portion that faces the engaged portion 16a through a hollow portion, and further has a vertically symmetrical shape. Similarly, the protrusion 31 is also formed in the lower part. As a result, the metal fitting cover 30 is formed with the protruding portion 31 at a position outside the engaging direction 16a of the receiving portion 16 in the direction of finding. Further, the protrusion 31 is located at a horizontal position above and below the engaged portion 16a.

  FIG. 4 is a cross-sectional view of the summoning rods 43 and 43 in a state where the inner and outer children 4a and 4b are closed, and shows a state where the crescent 10 is not locked. As shown in this figure, in this state, the handle 13 of the crescent 10 is disposed downward, and the hanging portion 12 is disposed on the indoor side. The engaged portion 16a formed on the receiving portion 16 of the external obstacle 4b is disposed at a position facing the hook 12 of the crescent 10 with the internal obstacle 4a and the external obstacle 4b closed. Further, the protruding portion 31 formed on the metal cover 30 is disposed at a position facing the box portion 11 of the crescent 10.

  FIG. 5 shows a state in which the crescent 10 is locked from the state of FIG. As shown in this figure, in this state, the handle 13 of the crescent 10 is disposed upward, and the hanging portion 12 is engaged with the engaged portion 16 a of the receiving portion 16. Here, from the box part 11 of the crescent 10, the trigger part 23 of the rotation restricting mechanism 20 provided therein protrudes, and the tip part 23a abuts against the tip part 31a of the projection part 31 of the metal cover 30. .

  Thus, in the state in which the hook 12 of the crescent 10 can be engaged with the engaged portion 16a of the receiving portion 16 in a state in which the inner shroud 4a and the outer obstacle 4b are completely closed, the handle 13 of the crescent 10 The trigger part 23 which protrudes toward the outdoor side from the box part 11 with rotation is brought into contact with the protruding part 31 of the metal fitting cover 30 formed outside the engaged part 16a of the receiving part 16 in the finding direction. Thereby, the rotation restricting mechanism 20 releases the lock for the rotation of the handle 13. That is, in the state in which the inner impingement 4a and the outer impoverishment 4b are completely closed, the handle 13 of the crescent 10 is not restricted by the rotation restricting mechanism 20 and the hanging portion 12 is the engaged portion of the receiving portion 16. It can be rotated to a position engaging with 16a.

  FIG. 6 shows a cross-sectional view of the summon bars 43 and 43 in a state in which the inner shoji 4a and the outer shoji 4b are not closed. As shown in this figure, when the handle 13 of the crescent 10 is rotated in this state, the trigger portion 23 of the rotation restricting mechanism 20 protrudes from the box portion 11, and in this case, the protrusion portion 31 extends in the protruding direction of the trigger portion 23. Since there is no obstacle like this, it protrudes further to the outdoor side than the case of FIG. Then, the rotation restricting mechanism 20 locks the rotation of the handle 13 so that the handle 13 cannot be further rotated in the locking direction. As a result, it is possible to prevent the crescent from being hung up when the inner shroud 4a and the outer shroud 4b are not completely closed.

  In the state of FIG. 6, if the inner arm 4a or the outer arm 4b is moved while the handle 13 of the crescent 10 is held in a locked state to attempt to completely close it, the trigger portion 23 on the side of the crescent 10 receives the Interfering with the protrusion 31 on the part 16 side. However, the trigger portion 23 is formed so as to be retracted when pressed to the indoor side even when the handle 13 is locked, and the tip portion 23a of the trigger portion 23 and the tip portion 31a of the projection portion 31 are both chamfered at the corners. By being formed in a polygonal shape, the trigger portion 23 comes into contact with the protruding portion 31 in an inclined manner even when the inner shroud 4a or the outer shroud 4b is moved while the handle 13 is locked. Therefore, the trigger portion 23 is pushed into the box portion 11 by the protruding portion 31, and as a result, the handle 13 is unlocked by the rotation restricting mechanism 20 as shown in FIG. 5.

  Further, the inner impingement 4a and the outer impingement 4b are opened larger than the state of FIG. 6, and the trigger portion 23 protrudes from the engaged portion 16a of the receiving portion 16 toward the inner position of the inner impingement 4a. Even in this case, the protruding portion 31 is formed above and below the engaged portion 16a of the receiving portion 16, and the trigger portion 23 is provided so as to abut against the protruding portion 31 formed above. Therefore, the trigger part 23 protruding from the box part 11 to the outdoor side does not interfere with the engaged part 16 a of the receiving part 16. Therefore, also in this case, the shojis 4 and 4 can be moved to be in a completely closed state while the handle 13 is locked.

  As described above, the protrusion 31 is formed in the receiving portion 16 at a position outside the engaged portion 16 a in the direction of finding, and the trigger portion 23 protrudes from the box portion 11 of the crescent 10 and comes into contact with the protrusion 31. Since the lock on the handle 13 is released, the hanging portion 12 is the same as that of a crescent that does not have an empty hanging prevention function, and the rotation restricting mechanism 20 can be hidden from the outdoor side. The sash can be highly effective in crime prevention. Further, since the horizontal position of the trigger portion 23 and the projection portion 31 is set above or below the engaged portion 16a of the receiving portion 16, the shoji is not completely closed and the trigger portion 23 protrudes. Even if the shoji is moved in this state, the sash does not interfere with the engaged portion 16a of the receiving portion 16 and the receiving portion 16 is not damaged by the trigger portion 23.

  Next, the internal structure of the box part 11 will be described. FIG. 7 is a front view of the crescent 10 showing the internal structure of the box portion 11. This figure shows the arrangement of the members in a state in which the hanging portion 12 is engaged with the receiving portion 16. As shown in FIG. 7, inside the box portion 11, there is a rotating body 21 that rotates in conjunction with the handle 13, a slide portion 22 that slides in conjunction with the rotating body 21, and a screw that is attached to the slide portion 22. The rotation restricting mechanism 20 is configured by accommodating a trigger portion 23 that is attached and protrudes outward from the opening portion 11 a of the box portion 11 as the slide portion 22 slides. Here, the slide part 22 is biased by the spring 24 in the protruding direction of the trigger part 23. The rotating body 21 is also biased in the rotating direction by the spring 25. The rotating body 21 is formed with a projecting latching portion 21f, and the spring 25 is hooked and fixed to the latching portion 21f.

  The rotating body 21, the slide part 22, and the trigger part 23 constituting the rotation prevention mechanism 20 will be described in more detail. In FIG. 8, the front view of the rotation prevention mechanism 20 in the unlocked state of the crescent 10 is shown. As shown in this figure, the rotating body 21 constituting the rotation restricting mechanism 20 is formed in a substantially disk shape, and a surface (back side in FIG. 8) facing the slide portion 22 has a notch-like engagement. A stop 21a is formed. In addition, a pressed portion 21b protruding in a bar shape is formed on the same surface as the locking portion 21a. On the other hand, a stopper 22a that protrudes toward the rotating body 21 is formed on the surface of the slide portion 22 that faces the rotating body 21, and a notch shape that is disposed so as to be in pressure contact with the pressed portion 21b of the rotating body 21. The pressing portion 22b is formed. As described above, the slide portion 22 is biased by the spring in the protruding direction of the trigger portion 23, and in the state of FIG. 8, the pressing portion 22 b of the slide portion 22 presses the pressed portion 21 b of the rotating body 21. The slide portion 22 is stationary due to the reaction force.

  FIG. 9 shows a front view of the rotation restricting mechanism in which the handle 13 is rotated from the state of FIG. The rotating body 21 rotates with the rotation of the handle 13, and the pressed portion 21b moves outward. Along with this, the slide portion 22 urged toward the outside also moves toward the outside, and the trigger portion 23 largely protrudes from the opening portion 11 a of the box portion 11. This is a case where there is no obstacle to the protrusion of the trigger portion 23, and the state shown in FIG. 9 is obtained when the inner obstacle 4a and the outer obstacle 4b are not completely closed. Then, the locking part 21a of the rotating body 21 comes into contact with the stopper 22a of the sliding part 22, and the rotating body 21 cannot be rotated any more. That is, the handle 13 is locked.

  FIG. 10 shows a state in which the trigger portion 23 is in contact with the protruding portion 31 of the metal cover 30. In other words, in this case, the inner limb 4a and the outer limb 4b are completely closed. When the distal end portion 23a of the trigger portion 23 comes into contact with the distal end portion 31a of the projection portion 31, the slide portion 22 and the trigger portion 23 do not move further outward. In this state, since the stopper 22a of the slide portion 22 is also stationary inside, the locking portion 21a of the rotating body 21 does not interfere with the stopper 22a of the slide portion 22, and the rotating body 21 can freely rotate. can do.

  Thus, the trigger part 23 protrudes greatly from the box part 11 with rotation of the handle 13, and protrudes to the outdoor side from the protrusion part 31 formed so that it may protrude to the indoor side in the summoning bowl 46 of the external obstacle 4b. Then, since the rotation of the handle 13 is locked by the slide portion 22, it is possible to prevent the crescent from being hung in the state in which the inner limb 4a and the outer limb 4b are not completely closed. .

  As illustrated in FIG. 7, the box unit 11 is provided with an operation body 50 that functions as an auxiliary lock that is slidable in the vertical direction. This auxiliary lock is for locking the handle 13 in a state in which the hanging portion 12 is engaged with the receiving portion 16 so that the handle 13 cannot rotate. The operating body 50 is held by the box unit 11 so that the position relative to the box unit 11 can slide from the first position to the second position above it. In FIG. 7, the operating body 50 is disposed at the first position, and is locked so that the handle 13 cannot be rotated.

  The operation body 50 is exposed to the outer surface of the box portion 11 and can be slid up and down by the user, and is formed so as to project inside the box portion 11 in a predetermined case. A rotation preventing portion 52 having a function of contacting the rotating body 21 and blocking the rotation, and an engaging portion 53 formed in a claw shape inside the box portion 11 and capable of engaging with the rotating body 21 in a predetermined case. And the arm part 55 extended toward the rotary body 21 side is formed. The operating body 50 is constantly urged by the elastic body 54 in the box portion 11 in the direction from the second position to the first position, that is, in the downward direction in the figure. In addition, the arm portion 55 is formed only on the front side of the operation body 50 so as not to interfere with the protruding portion 21 c of the rotating body 21.

  A display unit 11b is provided on a wall surface of the box unit 11 on which the operation body 50 is provided. The display unit 11 b is embedded in the wall surface of the box unit 11 and has a surface exposed to the outside, and is colored in a color different from the box unit 11, for example, green. In addition, the display unit 11b is arranged to be above the upper end of the operation body 50 when the operation body 50 is in the first position. Therefore, when the operating body 50 is in the first position, that is, when the rotation of the handle 13 is locked, it can be visually recognized that it is exposed to the outside and is in a locked state. On the other hand, when the operating body 50 moves to the second position side, the display unit 11b is covered with the operating body 50 and cannot be viewed from the outside.

  In addition to the locking portion 21a and the pressed portion 21b for functioning as the rotation restricting mechanism 20, the rotating body 21 has a mechanism for automatically sliding the operating body 50 as the handle 13 rotates. Is provided. As shown in FIG. 8, as a mechanism for this, the rotating body 21 is formed with a protruding portion 21c in which a part in the circumferential direction protrudes in the radial direction. The surface of the protruding portion 21c that faces the operating body 50 is a flat contact portion 21d that contacts the rotation preventing portion 52 in a predetermined case. Further, a notched engaged portion 21e that can be engaged with the engaging portion 53 of the operating body 50 is formed on the surface of the rotating body 21 on which the locking portion 21a is formed. Further, the rotating body 21 is formed with a protruding arm holding portion 21g at a position adjacent to the above-described hooking portion 21f. Since the arm holding portion 21g and the latching portion 21f are formed so as to protrude, the arm holding portion 21g and the latching portion 21f can be linked to the arm portion 55 of the operating body 50 as the rotating body 21 rotates.

  Next, the operation of the operating body 50 accompanying the rotation of the handle 13 will be described. First, the operation from the state in which the hanging portion 12 is engaged with the receiving portion 16, that is, the locked state and the auxiliary lock is applied, to the release of the auxiliary lock and the unlocked state will be described. FIG. 11 is a front view showing the internal structure of the crescent 10 in the locked state and the auxiliary lock is applied. In the subsequent drawings, the configuration of the rotation prevention mechanism 20 is omitted for simplicity.

  As shown in FIG. 11, when the crescent 10 is in a locked state, the rotating body 21 is arranged in the rotational direction position where the protruding portion 21 c is the uppermost portion in the box portion 11. In addition, the operating body 50 is disposed at the first position with respect to the box portion 11. In this state, the contact portion 21d formed on the protrusion 21c of the rotating body 21 is adjacent to the planar contact surface 52a formed on the rotation blocking portion 52 of the operating body 50. Cannot rotate counterclockwise in the figure. That is, in this state, the handle 13 is locked so that it cannot be rotated in the unlocking direction. Further, in this locked state, since the upper end of the operation unit 51 is located below the display unit 11b provided in the box unit 11, the display unit 11b is exposed to the outside. Thereby, it can be visually recognized from the outside that the handle 13 is in the locked state.

  FIG. 12 is a front view showing the internal structure of the crescent 10 in a locked state where the auxiliary lock is released. As shown in this figure, when the operating portion 51 of the operating body 50 is slid to move the operating body 50 from the first position to the second position above it, the engaging portion 53 of the operating body 50 is Engage with the engaged portion 21 e of the rotating body 21. Thereby, the operating body 50 urged by the elastic body 54 in the direction from the second position toward the first position can be stopped at the second position.

  Further, when the operating body 50 is moved from the first position to the second position above the first position, the rotation preventing portion 52 is also moved upward from a position adjacent to the protruding portion 21 c of the rotating body 21. As a result, the rotating body 21 is released from the adjacent state with the contact surface 52a and can rotate counterclockwise in the figure. That is, in this state, the handle 13 can be rotated in the unlocking direction. Further, when the operation body 50 is moved from the first position to the second position, the operation unit 51 covers the surface of the display unit 11b, so that the display unit 11b cannot be seen from the outside. Thereby, it can be visually recognized from outside that the handle 13 is not locked.

  FIG. 13 is a front view showing the internal structure of the crescent 10 in a state where the handle 13 is rotated by 10 ° in the unlocking direction with respect to the state of FIG. As shown in this figure, when the handle 13 is rotated in the unlocking direction, the rotating body 21 is rotated accordingly. The engaging portion 53 of the operating body 50 maintains the engaged state of the rotating body 21 with respect to the engaged portion 21e until the handle 13 shown in FIG. 13 is rotated by 10 ° in the unlocking direction.

  FIG. 14 is a front view showing the internal structure of the crescent 10 in a state in which the handle 13 is rotated by 45 ° in the unlocking direction with respect to the state of FIG. As shown in this figure, when the handle 13 is further rotated from the state of FIG. 13 in the unlocking direction, the engaged state of the rotating body 21 with the engaged portion 21e by the engaging portion 53 of the operating body 50 is released. The At this time, the operating body 50 urged downward by the elastic body 54 moves toward the first position side, but the vicinity of the tip of the arm portion 55 is in contact with the latching portion 21f of the rotating body 21. The contact is supported against the urging force of the rotating body 21, and the operating body 50 is regulated so as not to move further downward and remains on the second position side. Even in this state, the operation unit 51 covers the surface of the display unit 11b so that the display unit 11b cannot be seen from the outside.

FIG. 15 is a front view showing the internal structure of the crescent 10 in a state where the handle 13 is rotated by 90 ° in the unlocking direction with respect to the state of FIG. As shown in this figure, when the handle 13 is further rotated in the unlocking direction from the state of FIG. 14, the latching portion 21f of the rotating body 21 moves in the circumferential direction and is positioned above the state of FIG. And the arm part 55 of the operation body 50 supported by the latching | locking part 21f also moves upwards in connection with it. As a result, the operating body 50 slightly moves to the second position side from the state of FIG. Even in this case, since the operation unit 51 covers the surface of the display unit 11b, the display unit 11b is not visible from the outside.

  FIG. 16 is a front view showing the internal structure of the crescent 10 in a state in which the handle 13 is rotated in the unlocking direction by 135 ° with respect to the state of FIG. As shown in this figure, when the handle 13 is further rotated from the state shown in FIG. 15 in the unlocking direction, the arm holding portion 21g of the rotating body 21 supports the arm portion 55, and the operating body is continuously operated by the rotating body 21. 50 is supported.

  FIG. 17 is a front view showing the internal structure of the crescent 10 in a state where the handle 13 is rotated to the unlocked position. When the handle 13 is rotated to the unlocked position, the rotating body 21 is in the rotational direction position in the box portion 11 where the protruding portion 21c is the lowest portion. Further, the operating body 50 is in a state in which the base portion of the arm portion 55 is supported by the arm holding portion 21g of the rotating body 21, and the state on the second position side is held.

  When the handle 13 is rotated in the locking direction from the state of FIG. 17, the rotating body 21 rotates while supporting the operating body 50 by the arm holding portion 21g and the latching portion 21f, and in order to FIG. 16, FIG. 15, and FIG. It will be in the state shown. FIG. 18 is a front view showing the internal structure of the crescent 10 in a state in which the handle 13 is rotated by 165 ° in the locking direction with respect to the state of FIG. As shown in this figure, when the handle 13 is further rotated in the locking direction from the state shown in FIG. 14, the hook portion 21 f moves in the circumferential direction, so that the arm portion 55 of the operating body 50 is rotated by the rotating body 21. The operating body 50 is moved toward the first position by the urging of the elastic body 54. However, since the lower surface of the rotation preventing portion 52 of the operating body 50 contacts the upper surface of the protruding portion 21c of the rotating body 21, the operating body 50 is restricted from moving further to the first position side. That is, after the support of the arm portion 55 by the hooking portion 21f is released, the rotation preventing portion 52 is supported by the protruding portion 21c, so that the operating body 50 is continuously supported by the rotating body 21, The state at the position 2 is maintained.

Can increase the sex. Further, when the handle 13 is operated in the unlocking direction, it is necessary to manually operate the operating body 50, so that the crime prevention property can be further enhanced. Further, when the operating body 50 is in the first position, the display unit 11b is exposed, and after the operating body 50 is slid to move from the first position to the second position, the handle 13 is again in the locked position. Since the display unit 11b is covered with the operation unit 51 until the operation unit 50 is moved to the first position after being rotated, it is determined whether or not the rotation of the handle 13 is locked by the operation unit 50. It can be easily visually recognized from the outside.

  Further, the rotation of the rotating body 21 functions to prevent emptying by the rotation blocking mechanism 20 and automatic auxiliary locking of the handle 13 by the operating body 50. It can also be provided selectively. In the embodiment described so far, the crescent is provided with both the emptying prevention function and the automatic auxiliary lock function, but the trigger part 23 is not provided, and the opening part 11a of the box part 11 is closed, A crescent that does not have an emptying prevention function and has only an automatic auxiliary lock function can also be used. Further, by replacing the operating body 50 with one that does not have the engaging portion 53 and not providing the elastic body 54, the crescent having only an anti-hanging function without an automatic auxiliary lock function. It can also be. Furthermore, a crescent that does not have both of these functions may be used. These can be appropriately selected according to the needs of the user.
