The lowering member 14 includes a fixing member 15 that fixes the lowering member 14 to the handle portion 12.

  The holder main body 13 is a resin member, and the insertion portion 11 and the handle portion 12 are integrally formed. The insertion portion 11 has a rectangular parallelepiped shape with a longitudinal section having a vertically long rectangular shape. A plurality of grooves 16 for preventing resin deformation are formed on the left and right side surfaces, and ribs for preventing reverse insertion. 17 protrudes.

  A recess 18 for engaging / disengaging with the locking / unlocking mechanism is formed on the upper surface of the insertion portion 11. Since the locking / unlocking mechanism departs from the spirit of the present invention, a brief description will be given with reference to FIG. 6. An engagement lever that is a part of the locking / unlocking mechanism with the key holder 2 inserted into the key holder insertion portion 4. The key holder 2 is locked or unlocked to the apparatus main body 3 by rotating around the fulcrum 20A and engaging / disengaging with the recess 18.

  Here, each key holder 2 can be inserted only into the key holder insertion portion 4 assigned thereto. In knitting the key holder 2, an identification plate 51 made of a member different from the holder body 13 is used in the present embodiment. The identification plate 51 is made of a vertically long sheet metal material. As shown in FIG. 3, the identification plate 51 is fitted around the inner groove of the insertion portion 11 around one side edge, and fitted around the inner groove of the lid 11A around the other side edge. It is laid out on the front end surface of the insertion portion 11 (the surface facing the key holder insertion portion 4).

  As shown in FIG. 7A, the identification plate 51 is regarded as a member having virtual sections of 20 squares in total, for example, 10 vertical and 2 horizontal, and a large number of key holders 2 are combined depending on the combination of the presence or absence of holes in each square. Can be organized. Of course, the shape of the identification plate 51 is different for each key holder 2, but since the identification plate 51 is made of a sheet metal material, it is only necessary to change the position of the punching pin of the mold at the time of manufacturing, and the burden of the manufacturing cost. There is almost no. The pin forming plates 52 and 53 shown in FIG. 7B are members fixed to the apparatus main body 3 side, and only the regular key holder 2 can be inserted by inserting the pins through the holes of the identification plate 51. . Although the shape of the pin forming plates 52 and 53 is different for each key holder 2, since the pin forming plates 52 and 53 are also made of a sheet metal material, it is only necessary to change the position of the punching pin of the mold. As described above, when the key holder 2 is knitted, by using the identification plate 51 made of a sheet metal material, only one resin mold of the holder body 13 is required, and the manufacturing cost of the key holder 2 can be suppressed. it can.

  Returning to FIGS. 2 and 3, the handle portion 12 is a portion having a rectangular parallelepiped shape that extends horizontally with the front upper portion of the insertion portion 11 as a base end, and is used when inserting / removing the key holder 2. It becomes a part grasped by. A triangular insertion direction mark 19 is formed on the upper surface of the grip portion 12 so that one apex faces the insertion portion 11 side. The triangular insertion direction mark 19 is integrally formed in a convex shape. It can be instantaneously determined that the insertion is performed with the insertion portion 11 side facing the key holder insertion portion 4 side. The upper surface and both side surfaces of the handle portion 12 protrude from the upper surface and both side surfaces of the insertion portion 11 with a slight step so that the handle portion 12 cannot be inserted into the key holder insertion portion 4.

  The handle portion 12 includes a locking claw through-hole 21 having a horizontally long hole cross-section penetrating over both side surfaces of the handle portion 12, and a circular cross-sectional protrusion positioned on both sides of the locking claw through-hole 21. Part through-holes 22 and 22 are formed. An insertion groove (slit 23) (see FIGS. 4 and 5) through which the bent portion 27 of the key suspension member 14 is inserted is formed from the periphery of the central portion of each through hole 22 for each protrusion to the lower surface of the handle portion 12. Has been. Further, a slit 24 into which one rising portion 29 of the key hanging member 14 is inserted is formed on the front end surface of the insertion portion 11. The both sides of the handle portion 12 have the same shape as each cover and a depth corresponding to the thickness of the cover so that a first fixed cover 31 and a second fixed cover 32 to be described later can be fitted flush with each other. A recess 25 is formed. Around the center of the lower edge of each recess 25, a notch 26 is formed for exposing the center of each lower edge of the first fixed cover 31 and the second fixed cover 32.

  The key suspension member 14 is a so-called key ring, and is made of, for example, a metal wire having a relatively large diameter. The key suspension member 14 of the present embodiment has a substantially trapezoidal shape, the upper center is formed as an opening for keying, and the upper ends are formed as bent portions 27 that are bent inward. The lower part of the key suspension member 14 is formed as a horizontal linear part 28, and an inclined rising part 29 is formed from the end of the linear part 28 to each bent part 27.

  In this embodiment, the fixing member 15 responsible for fixing the key suspension member 14 to the handle portion 12 includes a first fixing cover 31 and a second fixing cover 32 attached to the left and right side surfaces of the handle portion 12. Both the first fixed cover 31 and the second fixed cover 32 are made of a resin member. At least one surface of the first fixed cover 31 and the second fixed cover 32 is provided with a number for easily identifying the key holder 2 by visual recognition, for example.

  The first fixed cover 31 and the second fixed cover 32 have locking claws 33 and 34 for attachment to the handle portion 12, respectively. The first fixed cover 31 and the second fixed cover 32 are attached so that the locking claw 33 and the locking claw 34 are locked so that both of them are brought into close contact with the side surface of the handle portion 12.

  Referring to FIGS. 3 and 5, the first fixed cover 31 has a horizontally long rectangular shape, and a rectangular flat plate that is perpendicular to the back surface and extends in the vertical direction around the center of the back surface. A pair of locking claws 33 formed with a gap are formed at intervals in the lateral direction. The claw of each locking claw 33 is projected so as to be opposite to each other. The second fixed cover 32 also has a substantially rectangular shape that is substantially the same as the first fixed cover 31, and a rectangular flat plate that is perpendicular to the back surface and extends in the vertical direction around the center of the back surface, and has a claw formed at the leading edge. A pair of locking claws 34 are formed at a wider interval than the interval between the locking claws 33 on the first fixed cover 31 side. The claw of each locking claw 34 is projected on the opposite side. In addition, on the back surface of the first fixed cover 31, ribs 43 for preventing intrusion of tools and the like are formed on the upper edge and the lower edge of the cover between the locking claws 33, 33.

  In addition, on the back surface of the first fixed cover 31, a columnar protrusion 35 protrudes outwardly in the lateral direction of each locking claw 33. Strictly speaking, the projecting portion 35 has a truncated cone shape having an inclined surface that becomes narrower toward the tip. On the back surface of the second fixed cover 32, a substantially cylindrical protrusion 36 into which the protrusion 35 on the first fixed cover 31 side is inserted protrudes laterally outside each locking claw 34. A plurality of axial cuts 37 (FIG. 3) are formed on the peripheral wall of the projection 36 so that the diameter can be expanded and contracted by elasticity, and the front end edge of the projection 36 has an engagement flange facing outward. 38 protrudes. An inclined surface 39 is formed outside the upper end of the engagement flange 38 as shown in FIG.

  A thin portion 40 is locally formed in at least one of the first fixed cover 31 and the second fixed cover 32. In the present embodiment, a V-groove 41 is formed along the vertical direction in the center in the lateral direction of the back surface of the second fixed cover 32, and the thin portion 40 is formed between the groove bottom of the V-groove 41 and each cover surface. . That is, the thin portion 40 is formed between the pair of engaging claws 34 in the second fixed cover 32. The lower end of the thin portion 40 faces the notch 26 described above. When an external force to be removed from the handle portion 12 is applied to the second fixed cover 32, the thin portion 40 is broken before the locking claw 33 and the locking claw 34 are released.

  The procedure for assembling the key holder 2 having the above configuration will be described. First, the key suspension member 14 is inserted into the handle portion 12 through the slit 23 in a state where the upper end (the bent portion 27) is slightly bent inward. One rising portion 29 is fitted into the slit 24. When the insertion of the key suspending member 14 is completed, the key suspending member 14 is easily dropped from the handle portion 12 because the area around the upper end of the key suspending member 14 is pressed against the inner wall of the handle portion 12 by its elastic restoring force. There is no.

  Next, the second fixed cover 32 is fitted into the recess 25 of the handle portion 12. The locking claw 34 is positioned in the locking claw through hole 21, and the protrusion 36 is inserted into the protrusion through hole 22. In the process in which the protruding portion 36 is inserted into the protruding portion through hole 22, the engagement flange 38 is pushed by the inner wall of the protruding portion through hole 22 and has a reduced diameter because the notch 37 is provided. Inserted. At the time of insertion, the presence of the inclined surface 39 shown in FIG. 5 prevents the slit 23 passing therethrough from being caught. When the engagement flange 38 reaches a diameter-enlarged portion formed at one end of the projection-use through hole 22, the engagement flange 38 released from the inner wall of the projection-use through-hole 22 is expanded by an elastic restoring force, It engages with the engagement surface 42 of the inner wall of the handle portion 12.

  Next, when the first fixed cover 31 is fitted into the recess 25 of the handle portion 12, the locking claw 33 engages with the locking claw 34 of the second fixed cover 32 in the through hole 21 for the locking claw, and the protruding portion In the through hole 22 for use, the protrusion 35 is inserted in a manner that is in close contact with the hollow inner wall of the protrusion 36. Therefore, even when a force in the direction of removing the engagement flange 38, that is, a force that moves the engagement flange 38 in the diameter reduction direction, the movement of the engagement flange 38 is restricted by the protrusion 35. The engagement surface 42 does not come off.

  As described above, the key suspension member 14 is fixed to the handle portion 12 by the bending portion 27 engaging with the projection portion 36. Since the first fixed cover 31 and the second fixed cover 32 are fitted in the respective recesses 25 and the edge of the cover is flush with the side surface of the handle portion 12 with almost no gap, it is difficult to forcibly open the cover.

  When the second fixed cover 32 is forcibly opened, the thin portion 40 is broken before the locking claws 33 and 34 are unlocked, so that it is instantly known that an illegal act has occurred. Of course, even when the handle portion 12 is destroyed, the trace remains in the handle portion 12, so that it is instantly known that an illegal act has occurred.

  In operation, when the administrator changes the key, the tool is inserted into the gap between the exposed handle portion 12 and the second fixed cover 32 using the notch portion 26, and the second fixing is performed. The cover 32 is broken and removed, and then the first fixed cover 31 is removed. After the key is changed, the new second fixed cover 32 and the first fixed cover 31 are used and reassembled by the above-described assembling procedure.

  As described above, the fixing member 15 (the first fixing cover 31 and the second fixing cover 32) has the locking claws 33 and 34 for attachment to the handle portion 12, and the fixing member 15 or the handle portion 12 is destroyed (plastic). If the disengagement of the locking claws 33 and 34 is made impossible without deformation, the grip portion 12 can be provided with a sealing function that suggests that there has been an illegal act due to traces of destruction. Therefore, unlike the conventional case, the key and the sealing tool are not mixed in the key hanging member, and the usability of the key is improved. The “attachment claw for attachment to the handle” is not limited to the engagement claw that is directly engaged with the handle, and the engagement between the engagement claws 33 and 34 as in the present embodiment. The locking claws 33 and 34 when the first fixed cover 31 and the second fixed cover 32 are attached to the handle portion 12 as a result of stopping are also included.

  Further, if the fixing member 15 includes the first fixed cover 31 and the second fixed cover 32 that are attached to the left and right side surfaces of the handle portion 12 by the locking claws 33 and 34 formed respectively being locked to each other, the cover There is no need to provide a latching claw that is easily subjected to an excessive force when prying open on the handle portion 12 side, that is, on the holder body 13 side. Therefore, when the cover is opened, only the first fixed cover 31 and the second fixed cover 32 need to be replaced. The holder body 13 which is larger and more expensive than these covers can be used as it is.

  Moreover, if the thin part 40 which breaks when the external force removed from the handle part 12 is applied to at least one of the first fixed cover 31 and the second fixed cover 32, the first fixed cover 31 or the second fixed cover 32 is provided. Since most of the broken parts can be collected in the thin-walled portion 40, the presence or absence of a trace of destruction can be instantly identified.

  Further, an insertion groove (slit 23) is formed on the lower surface of the handle portion 12, and the key suspension member 14 has a first fixed cover 31 and a second fixed cover around the upper portion inserted into the handle portion through the slit 23. If it is configured to be locked to the protrusions 35 and 36 formed on at least one of the back surfaces of each of the 32 and prevent downward, the key suspension member 14 can be fixed to the handle portion 12 with a simple structure. Only the protruding portion 35 or only the protruding portion 36 may be passed through the protruding portion through-hole 22, and one of them may be configured to lock the upper portion of the key hanging member 14.

  The key suspension member 14 has an opening at the upper center and a bent portion 27 that is engaged with the protrusions 35 and 36 at the upper end. The protrusions are formed on the first fixed cover 31 and the second fixed cover 32, respectively. 35 and 36 are formed, and when one protrusion 35 is inserted into the other cylindrical protrusion 36, when the key suspension member 14 is illegally pulled out from the handle 12, the bent portion 27 is formed. The force transmitted to the locking portion from the projection portion 35 and the projection portion 36 can be dispersed. Therefore, breakage of the engaging portion between the bent portion 27 and the protruding portions 35 and 36 can be prevented.

  Further, the other cylindrical protrusion 36 has a plurality of axial cuts 37 formed on the peripheral wall so that the diameter can be reduced, and an engagement flange 38 projects outwardly at the tip edge. When the first fixed cover 31 and the second fixed cover 32 are attached to the handle portion 12, the engagement flange 38 engages with the engagement surface 42 of the handle portion 12, and the engagement flange 38 moves in the reduced diameter direction. If it is configured to be restricted by the one projection 35, the engagement flange 38 is less likely to be disengaged, and the locking force of the second fixed cover 32 to the handle portion 12 can be further increased.

  Furthermore, if the lower part of the key suspension member 14 is formed as a horizontal linear portion 28, the adjacent keys in the linear portion 28 can be suspended closely, and a large number of keys are attached. Also not bulky.
