The hanging claw 24 is adapted to be engaged with a hanging groove 25 of the package body 3 to be described later when rotating around the shaft portions 17 and 18.

  On both sides of the package body 3, there are formed hooking grooves 25 for receiving hooking claws 24 that move in an arc when the operating lever 14 rotates around one of the shafts 17,18. The hooking groove 25 receives the hooking claws 24 so as to hold the positions of the shaft parts 17 and 18 so as not to remove the shaft parts 17 and 18, which are the rotation centers of the operation lever 14, from the holding grooves 19 and 20. It is supposed to be.

  The holding grooves 19 and 20 are formed on the front end surface of the package body 3 so as to be spaced apart from each other in the vertical direction and extend in the width direction. The holding grooves 19 and 20 are bent in opposite directions so that the shaft parts 17 and 18 are separated from the groove only when the holding shaft parts 17 and 18 rotate around the other shaft parts 18 and 17, respectively. The cross section is formed in a circular arc shape.

  Further, the package body 3 is formed with a notch portion 26 for allowing a finger to be hooked on the shaft portions 17 and 18 in the holding grooves 19 and 20. The cutout portion 26 is formed by forming cutouts that are continuous with the holding grooves 19 and 20 at the upper front portion and the lower front portion of the package body 3.

  The interference member 12 rotates the engagement lever 6 so as to be detached from the cage 2 when the operation lever 14 is tilted, and between the pivoted support portions 15 and 16 of the operation lever 14. It is connected to the engaging lever 6 so as to be slidable while being rotatably connected. The interference member 12 is supported by the package body 3 so as to be slidable in the front-rear direction, and is slidably connected to the operation lever 14 and a slide portion 27 for pushing and rotating the support lever portion 8 of the engagement lever 6, and the slide portion 27.

Thereby, the slide part 27 is engaged with the casing 50 so as to be slidable in the front-rear direction. Moreover, the slide part 27 is arrange | positioned under the support lever part 8 of the engaging lever 6, and the support lever part 8 is mounted. That is, the slide portion 27 is slidably engaged with the lower surface of the support lever portion 8. The slide portion 27 is configured to allow the engaging lever 6 to move upward by sliding forward and to allow the lowering of the engaging lever 6 by sliding backward.

  One end of the connecting portion 28 is rotatably connected to an intermediate position between the arm portions 21 and 22 of the operation lever 14, and the slide portion 27 is operated even when the operation lever 14 rotates about any of the shaft portions 17 and 18. Is configured to slide.

  Next, the operation of this embodiment will be described.

  As shown in FIGS. 1, 2, and 11, when the package 1 with a lock mechanism attached to the cage 2 is extracted from the cage 2, fingers are put on the shaft portions 17 and 18 exposed from either the upper or lower cutout 26. Hang and pull forward. At this time, even if both shaft portions 17 and 18 are accidentally pulled forward simultaneously, the holding grooves 19 and 20 are formed in an arc shape in cross section, so that both shaft portions 17 and 18 come out of the holding grooves 19 and 20. Therefore, the operation lever 14 is not detached from the package body 3.

  As shown in FIGS. 5 and 12, when the upper shaft portion 17 is pulled forward, the operation lever 14 starts to rotate around the lower shaft portion 18. When the operation lever 14 starts to rotate, the hooking claws 24 of the arm portions 21 and 22 enter the hooking groove 25, and the operation lever 14 can only rotate about the shaft portion 18 with respect to the package body 3. For this reason, even if the upper shaft portion 17 is detached from the holding groove 19, the operation lever 14 does not come off the package body 3.

  By the rotation of the operation lever 14, the slide portion 27 connected to the operation lever 14 via the connection portion 28 slides forward in conjunction with the operation lever 14 while the slide direction is regulated by the guide hole 29. Thereby, the slide part 27 pushes upward while rubbing the lower surface of the support lever part 8, and rotates the engagement lever 6 upward. At this time, if the curvature of the bottom surface 11 is formed sufficiently gently, the force when the slide portion 27 moves is extremely small, so the force received by the interference member 12 and the engagement lever 6 is small and is not easily broken. Further, since the engaging lever 6 is rotated by an extremely simple mechanism, there is no problem in component accuracy and the like, and the engaging lever 6 can be reliably and easily rotated.

  As shown in FIGS. 7, 8, and 13, when the operation lever 14 is almost completely tilted forward and the lock portion 10 of the engagement lever 6 is pulled upward from the engagement hole 9 of the cage 2, the lock is Canceled. By pulling the operation lever 14 forward in this state, the package 1 with the lock mechanism can be easily extracted from the cage 2.

  Further, when it is difficult to put a finger on the upper shaft portion 17, the lower shaft portion 18 may be pulled forward as shown in FIGS. Also in this case, as the operating lever 14 is rotated, the slide portion 27 is slid forward in conjunction with each other. Therefore, the lock can be released by rotating the engaging lever 6 upward as shown in FIGS. At this time, the direction in which the hooking claws 24 of the arm portions 21 and 22 enter the hooking groove 25 is restricted in the same manner as in the above-described embodiment, so that the lower shaft portion 18 is detached from the holding groove 20. Even if this is done, the operating lever 14 will not come off the package body 3.

  When the package 1 with the lock mechanism is attached to the cage 2, the posture of the operation lever 14 is returned to the original position and the package body 3 is inserted into the cage 2. The engaging lever 6 escapes upward by applying an inclined surface 13 formed at the protruding end of the locking portion 10 to the front end edge of the cage 2, and the locking portion 10 reaches the position of the engaging hole 9 to release the locking portion 10. Drop into the engagement hole 9. As a result, the package 1 with the lock mechanism is locked to the cage 2.

  As described above, the operation lever 14 has the two pivoted support portions 15 and 16 that are pivotably supported by the package body 3, and any one of these pivoted support portions 15 and 16 is arbitrarily selected. Since one is pivotally supported on the package body 3 and rotated, when a finger is put on the operation lever 14 for lever operation, the position where the finger is put can be selected as appropriate, and the release operation is easy. Can be.

  The pivotally supported portions 15 and 16 are shaft portions 17 and 18 that form the rotation center of the operation lever 14, and the holding grooves 19 and 20 that hold the shaft portions 17 and 18 so as to be detachable in the radial direction are provided in the package body 3. Therefore, the operation lever 14 and the support structure for the operation lever 14 can be simplified.

  Further, since the holding grooves 19 and 20 are formed in a circular arc shape that bends in opposite directions, only when the operation lever 14 rotates about one of the shafts 18 and 17, the other shaft 17 and 18 can be detached from the holding grooves 19 and 20, and the shaft portions 17 and 18 can be prevented from being separated from the package body 3 at the same time.

  Further, since the shaft portions 17 and 18 are also used as handles, the operation lever 14 can be simplified.

  And since the notch part 26 for hooking a finger | toe to the shaft parts 17 and 18 in the holding grooves 19 and 20 was formed in the package main body 3, a finger | toe can be easily hung on the shaft parts 17 and 18, and release operation can be performed. It can be easy.

  Further, the operation lever 14 has a hook claw 24 that is engaged with the package main body 3 when rotating about the shaft portions 17 and 18, and the package main body 3 holds the rotation center of the operation lever 14. Since it has a latching groove 25 for guiding the latching claw 24, it is possible to reliably prevent the shaft portions 17 and 18 from falling off the holding grooves 19 and 20 when the operation lever 14 is rotated. The lever 14 can be pivoted well.

  Then, the operation lever 14 is pivotally supported so as to be tiltable in the direction in which the package body 3 is pulled out, and the engagement lever 6 that is locked to the cage 2 so as to be able to be fastened and released is rotatably provided on the package body 3. Since the interference member 12 that rotates the engagement lever 6 so as to be detached from the cage 2 when tilted is provided on the operation lever 14, the lock portion 10 of the engagement lever 6 is moved to the cage 2 by tilting the operation lever 14. The package body 3 can be easily extracted from the cage 2 by pulling the operation lever 14 forward in this state.

  Further, since the interference member 12 is rotatably connected between the pivoted support portions 15 and 16 of the operation lever 14 and is slidably engaged with the engagement lever 6, the operation lever 14 and It is possible to prevent an excessive force from being applied to the interference member 12 and the engagement lever 6, and to make the lock fastening release operation mechanism 4 of the package 1 with a lock mechanism difficult to break. And the dimensional accuracy of the interference member 12 and the engagement lever 6 can be loosened.

  Further, an operation lever 14 that is rotatably provided on the casing 50, and is rotatably connected to the operation lever 14 and slidably engaged with the casing 50. When the operation lever 14 is rotated, the operation lever 14 is rotated. Since the package 1 with the locking mechanism is configured by including the interference member 12 for rotating the engagement lever 6 in conjunction with each other, the interference member 12 is linearly moved along the engagement lever 6 by rotating the operation lever 14. The engagement lever 6 can be rotated without difficulty. As a result, it is possible to prevent the engaging lever 6 and the operating lever 14 from being damaged due to excessive force and to be unstable in operation, and unlocking can be easily performed. Then, by adopting a simple mechanism that slides the interference member 12 and rotates the engagement lever 6 on the slide path of the interference member 12 while pushing the interference lever 12 away, the operation lever 14 and the interference member 12 are used. In addition, it is possible to loosen the dimensional accuracy of the parts related to unlocking, such as the engaging lever 6, and the package 1 with a lock mechanism can be manufactured at low cost.

  Further, the engaging lever 6 is pivotally supported so as to be able to rotate up and down so as to protrude downward from the casing 50 by its own weight, and the interference member 12 is slidably engaged with the lower surface of the engaging lever 6. Therefore, the mechanism for moving the engaging lever 6 out of the casing 50 can be simplified, and the package 1 with the lock mechanism can be manufactured at low cost.

  In addition, although the operation lever 14 shall have the two to-be-supported parts 15 and 16, the to-be-supported part may be two or more.

  The holding grooves 19 and 20 are formed in a circular arc shape in cross section, but may be formed in a hook shape.

  The shaft portions 17 and 18 as the pivoted support portions 15 and 16 are held in the holding grooves 19 and 20 formed in the package body 3 so as to be detachable in the radial direction. However, the present invention is not limited to this. For example, as shown in FIG. 16, a shaft portion 35 extending in the width direction is formed in the package body 3 in place of the holding grooves 19 and 20, and a groove portion surrounding the outer periphery of the shaft portion 35 in the radial direction on the operation lever 37. 36 may be formed as pivoted parts. In this case, the groove part 36 is preferably formed in a bent shape so as not to interfere with the shaft part 35 in the groove part 36 when rotating around the other non-corresponding shaft part 35. Specifically, the groove 36 is preferably formed in an arc shape or a hook shape that bends in opposite directions. At this time, the operation lever 37 has a hook claw 38 that is engaged with the package main body when rotating about the shaft portion 35, and the package main body holds the hook nail so as to hold the rotation center of the operation lever 37. It is preferable to have a hanging groove 39 for guiding 38.

  Further, the engaging lever 6 protrudes downward from the casing 50 by its own weight. However, as shown in FIG. 17, an elastic spring such as a spring is provided between the fixing system such as the casing 50 and the engaging lever 6. The urging means 51 may be provided so that the engaging lever 6 protrudes out of the casing 50 elastically. When the package 1 with the lock mechanism is attached to the cage 2, the engagement lever 6 can be elastically inserted into the engagement hole 9 to generate an operation sound, and the operator can lock the package 1 with the lock mechanism. You can be notified. Further, since the engaging lever 6 is forcedly protruded out of the casing 50 by the elastic biasing means 51, for example, even if the cage 2 is laid upside down, it can be mounted on the cage 2, and the degree of freedom in layout Can be increased.
