Yes. A communication hole 11h is formed in the approximate center near one short side of the bottom surface 11, and this communication hole 11h faces the through hole 80h of the mounting panel 80 (see FIG. 3). A guide portion 13 is formed in the vicinity of the communication hole 11 h so as to protrude outward in the vertical direction of the case body 10 in the insertion direction of the fastener 20. The communication hole 11h is crossed by the guide portion 13 and divided into two, and is formed in a slit shape. The communication hole 11 h is formed wider than the leg portion 22 of the fastener 20. An insertion projection 14 for attaching to the attachment panel 80 is formed at a substantially central portion near the other short side of the bottom surface 11 so as to protrude outward in the vertical direction of the case body 10. A convex portion 15 that engages with the lever 40 is formed at a substantially central portion near the pair of long sides of the bottom surface 11 so as to protrude inward of the case main body 10.

  In the inner wall 12, a pair of engaging claws 16 that come into contact with the hook 30 are formed in the approximate center of the pair of long side walls 12 n that are erected from the long side of the bottom surface 11. Note that the number of the engaging claws 16 is not limited to a pair, and may be a plurality of configurations.

  The guide portion 13 includes a base portion 13b that is connected to the bottom surface 11, a relief portion 13e that is narrowed from the base portion 13b toward the tip, and a leading portion 13t that is the tip and is wider than the base portion 13b. Yes. The base portion 13b has a step portion 13s formed by reducing the diameter.

  The fastener 20 includes two leg portions 22 that face each other and a hinge portion 23 that connects the leg portions 22, and has a substantially U shape when viewed from the side. The distance between the leg portions 22 is formed to be substantially the same as the width of the base portion 13b constituting the guide portion 13, and the base portion 13b of the guide portion 13 is sandwiched between the leg portions 22. A pair of claw portions 21 is formed at the tip of the leg portion 22. The claw portion 21 is composed of a guide side claw portion 21g facing inside the leg portions 22 facing each other and a panel side claw portion 21p formed on the back surface of the guide side claw portion 21g outside the leg portion 22.

  The hook 30 has a substantially square shape and is formed in an endless ring shape. A part of the hook 30 that is one side of a substantially rectangular shape is pivotally supported by the hinge portion 23 of the fastener 20 as a shaft portion 31, and becomes a shaft on which the hook 30 rotates. On the other side facing the shaft portion 31, a rope or the like for fixing the load is passed as the hook portion 32. The hook 30 has a connecting side 33 that connects the shaft portion 31 and the hooking portion 32 facing each other, and is formed in a U shape when viewed from the side. Note that the shape of the hook is not limited to an endless ring, and may be a substantially ring-shaped end with a gap formed between the ends facing each other by deforming from a rod shape to a ring shape, for example.

  The lever 40 includes a front end 42, a pair of side surfaces 43 formed so as to be inclined so that one edge gradually approaches the other edge from the wide side to the narrow side toward the front end 42. It is comprised from the upper surface which connects 43 inclined edges. The lever 40 is formed with a storage space 40s surrounded by the tip 42, the side surface 43, and the upper surface, and the fastener 20 is stored in the storage space 40s. The overall length of the lever 40 is smaller than the inner diameter of the hook 30. A groove 44 that is an engagement release portion is formed at the tip 42. The disengagement part may be a hole or a protrusion in addition to the groove 44. A shaft support portion 41 that rotatably supports the shaft portion 31 of the hook 30 and a support portion 45 that serves as a fulcrum when tilting are formed on the wide side of the side surface 43. The side surface 43 is formed with a concave portion 46 that engages with the convex portion 15 formed on the bottom surface 11 of the case body 10. The recess 46 may be a hole.

  Next, a method for assembling the latch 1 according to this embodiment will be described.

  2 and 3A, the hook 30 is attached to the fastener 20 so that the shaft portion 31 is sandwiched by the hinge portion 23. Since the fastener 20 is formed in a substantially U shape, the shaft portion 31 can be supported by the hinge portion 23 so as to be rotatable.

  The fastener 20 sandwiching the hook 30 is brought close to the bottom surface 11 of the main body case 10 from the leg portion 22 side, and the leg portion 22 is inserted into the communication hole 11h. Since the communication hole 11h is wider than the leg part 22, the leg part 22 can be inserted. When the fastener 20 is inserted until the leg portion 22 reaches the top portion 13t of the guide portion 13, the base portion 13b of the guide portion 13 is sandwiched between the leg portions 22, and the hinge portion 23 and the bottom surface 11 The shaft portion 31 is sandwiched.

  The lever 40 is put on the fastener 20 so as to be stored in the storage space 40s from the shaft support portion 41 side. At the same time, the shaft support portion 41 supports the shaft portion 31 constituting the hook 30. That is, the shaft portion 31 also serves as the rotation shaft of the lever 40. At this time, the lever 40 is in a state of standing on the bottom surface 11 with the shaft support portion 41 as a bottom. By supporting the shaft portion 31 with the shaft support portion 41, the hook 30 can be rotated.

  Next, regarding the action when attaching the latching tool 1 according to the present embodiment to the attachment panel 80, when the lever 40 in the standing state is tilted and engaged with the edge of the through hole 80h, the engagement is raised and released. A description will be given in the order of making them.

  3A, 3 </ b> B, and 3 </ b> C, the latch 1 is installed on the mounting panel 80 so that the communication hole 11 h of the bottom 11 constituting the case body 10 faces the through hole 80 h. Since the guide portion 13 formed in the case body 10 protrudes from the bottom surface 11 to the outside of the case body 10, it passes through the through hole 80 h. In the leg portion 22 of the fastener 20, the claw portion 21 communicates the communication hole 11h and the through hole 80h. The insertion protrusion 14 also penetrates through the other through hole of the attachment panel 80.

  In this state, the lever 40 erected as described above is rotated counterclockwise so as to be tilted about the shaft portion 31 constituting the hook 30. With the support portion 45 as a fulcrum, the lever 40 falls toward the bottom portion 11 of the case body 10, and the shaft support portion 41 leaves the bottom surface 11 while supporting the shaft portion 31. By tilting the lever 40, the shaft portion 31 is pulled up, and the support portion 45 slides along the bottom surface 11. When the shaft portion 31 is pulled up, the supported fastener 20 is retracted in the removal direction.

  In the fastener 20 that is retracted in the removal direction, the tip of the leg portion 22 is separated from the leading portion 13 t of the guide portion 13. When the fastener 20 is retracted until it is located in the vicinity of the through hole 80h, the claw portion 21 is opened from the escape portion 13e along the base portion 13b. The fastener 20 with the leg portion 22 opened is positioned by engaging the guide side claw portion 21g with the step portion 13s formed in the guide portion 13 and the panel side claw portion 21p engaging the edge of the through hole 80h. Is done. Moreover, the leg portions 22 facing each other sandwich the base portion 13b having substantially the same width on the inside, and the outside is sandwiched between the edges of the through hole 80h. Therefore, as for the fastener 20, the leg part 22 is controlled from an inner side and an outer side, and an open leg and a closed leg become impossible. With this configuration, the latch 1 can be reliably engaged.

  When the lever 40 is tilted completely, the concave portion 46 is engaged with the convex portion 15 formed by protruding from the bottom surface 11. The lever 40 can be reliably fixed by the concave portion 46 and the convex portion 15.

  The hook 30 is supported by the shaft support portion 41 so that the shaft portion 31 can rotate, and can be rotated even after the hooking tool 1 is engaged with the mounting panel 80. Since the hook 30 is formed in an endless annular shape, the strength of the shaft portion 31 is high, the load bearing strength is improved, and a holding force of at least about 1000 N can be secured. As described above, the same holding force can be ensured even if the hook has a substantially annular shape.

  In FIG. 4, when the hook 30 is rotated in the main body case 10, the connection side 33 comes into contact with the pair of engaging claws 16 formed on the long side wall 12 n of the inner wall 12, and the rotation is temporarily stopped. . When the hook 30 is further pushed and rotated so as to approach the bottom surface 11, the connecting side 33 is accommodated in the case body 10 beyond the engagement claw 16. The hook 30 is temporarily held with the connecting side 33 pressed from above by the engaging claw 16. The engagement claw 16 provides a click feeling when the hook 30 is rotated, and after the storage, the hook 30 is rotated by vibration or the like and is struck against the bottom surface 11 without causing noise.

  As described above, the latch 1 can be easily attached to the attachment panel 80.

  In FIGS. 3A, 3B, and 3C, when the tilted lever 40 is erected to release the engagement, the work can be easily performed using a tool (not shown). A tool such as a flat-blade screwdriver is inserted into the groove 44 formed at the tip 42 of the lever 40, and the lever 40 is lifted. At the same time, the engagement between the concave portion 46 of the long side wall 12n and the convex portion 15 formed protruding from the bottom surface 11 is released. Since the groove 44 is formed at the tip 42, it is possible to work in a larger space than the side surface 43 side, and it is only necessary to release the engagement at one point of the tip 42. The latch 1 can be removed by releasing the connection.

  The lever 40, which has been disengaged from the convex portion 15, is rotated clockwise so as to be raised about the shaft portion 31 constituting the hook 30. The lever 40 has the support portion 45 as a fulcrum, the tip 42 is separated from the bottom portion 11 of the case body 10, and the shaft support portion 41 approaches the bottom surface 11 while supporting the shaft portion 31. By raising the lever 40, the shaft portion 31 is pushed down, and the support portion 45 slides along the bottom surface 11. When the shaft portion 31 is pushed down, the supported fastener 20 enters in the insertion direction.

  In the fastener 20 that has entered the insertion direction, the tip of the leg portion 22 reaches the leading portion 13 t of the guide portion 13. When the claw portion 21 moves away from the through hole 80h and enters the escape portion 13e, the fastener 20 is closed from the base portion 13b along the escape portion 13e. The fastener 20 whose legs 22 are opened is disengaged between the guide claw portion 21g and the step portion 13t formed in the guide portion 13, and the engagement between the panel claw portion 21p and the edge of the through hole 80h. The alignment is released and the positioning is released. Further, the leg portions 22 facing each other sandwich the escape portion 13e inside. Therefore, since the leg part 22 comes to bend inward by the space of the escape part 13e, the fastener 20 can be closed.

  The fastener 20 is pulled out without being engaged with the edge of the through hole 80h because the leg portion 22 fits in the width of the leading portion 13t and bends inward, so that the fastener 20 can easily be hooked from the mounting panel 80. 1 can be removed.

  As described above, in the present embodiment, the shaft portion 31 is accommodated inside the case body 10 without being exposed to the outside. Therefore, there is no possibility of being caught outside and being damaged during installation.

  Moreover, in this embodiment, it was set as the structure which can attach the latching tool 1 to the attachment panel 80 by inclining the lever 40, and can be removed by making the lever 40 stand up. Therefore, since it is not necessary to fix with a metal bolt and it can attach with one touch, the man-hour of bolt fastening reduces, workability | operativity improves, and it contributes also to weight reduction by the reduction of metal parts.

  In the present embodiment, the case body 10 is formed in a bathtub shape that can accommodate the fastener 20, the hook 30, and the lever 40. The lever 40 is formed with a storage space 40s in which the fastener 20 is accommodated. Is formed smaller than the inner diameter of the hook 30. That is, the lever 40 is accommodated in the inner diameter of the hook 30, the fastener 20 is accommodated in the storage space 40 s of the lever 40, and these are accommodated in the case body 10. Therefore, it is preferable also in appearance.

  Further, in the present embodiment, the lever 40 is inclined so that one edge gradually approaches the other edge as the side surface 43 moves from the wide side where the shaft support portion 41 is formed toward the tip 42 which is the narrow side. Is formed. That is, when the lever 40 is attached to the case body 10 and tilted, a large space can be taken in the vicinity of the tip 42, so that a tool or a finger can be easily inserted and operability is good.

  Further, in the present embodiment, the hook 30 is formed in a U-shape when viewed from the side, with the connecting side 33 that connects the shaft portion 31 and the hooking portion 32 facing each other being bent. Therefore, the hook 30 is accommodated along the bottom surface 11 from the bent portion toward the hook portion 32 even when the shaft portion 31 is pulled up by the tilt of the lever 40, and the hook portion 32 slightly floats from the bottom surface 11. Therefore, it is easy to put a finger or a tool in the gap between the bottom surface 11 and the hook portion 32, and operability is good.

  Further, in the present embodiment, a convex portion 15 that engages with the lever 40 is formed so as to protrude in the vertical inner side of the case main body 10 at approximately the center of the bottom surface 11 constituting the case main body 10 near the pair of long sides. On the other hand, a concave portion 46 that engages with the convex portion 15 is formed on the side surface 43 of the lever 40. These concave portions and convex portions may be configured in reverse. That is, the bottom surface concave portion may be formed in the center of the bottom surface 11 near the pair of long sides, and the lever convex portion that engages with the bottom surface concave portion may be formed on the side surface 43 of the lever 40.

  In FIG. 5A, as a first modification of the present embodiment, the lever may be supported by the fastener. That is, in the first modification, the pivot shaft of the lever and the pivot shaft of the hook 30 are configured separately. In this case, a hook shaft support portion 241 is newly formed on the fastener 201 in addition to the hinge portion 231, and a lever shaft portion 411 that extends between the side surfaces 43 is formed on the lever 401 instead of the shaft support portion 41. The hinge portion 231 supports the lever shaft portion 411 formed on the lever 401, and the hook shaft support portion 241 supports the shaft portion 31 of the hook 30. Since other configurations are the same as those in the above embodiment, description thereof is omitted.

  Moreover, in FIG.5 (b), it is good also as a structure by which a fastener is supported by the lever 40 as a 2nd modification. That is, also in the second modified example, the rotating shaft of the lever 40 and the rotating shaft of the hook 30 are configured separately as in the first modified example. In this case, a fastener shaft portion 232 is newly formed on the fastener 202 instead of the hinge portion, and a hook shaft support portion 242 is separately formed. The fastener shaft portion 232 is supported by the shaft support portion 41 of the lever 40, and the shaft portion 31 of the hook 30 is supported by the hook shaft support portion 242. Since other configurations are the same as those in the above embodiment, description thereof is omitted.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment.
