That is, the first andsecond case members case members screw member 36 and joined to each other at one location aligned with the engaged locations. - Through
holes portion 27b of thefirst case member 27 and the one end second raisedportion 28b of thesecond case member 28, the throughholes second case members case 23. - The
magnet key 22 is formed by disposing a plurality of, for example three,magnets 41 on a magnet keymain body 40 made of a synthetic resin, the magnet keymain body 40 is formed so as to be long in the longitudinal direction of thecase 23 so that it can be stored in thestorage recess part 30, and one end part of the magnet keymain body 40 is pivotably supported on thecase 23. - A
recess part 42, a circular projectingpart 43 disposed in a central part of therecess part 42, and a plurality of, for example four,housing recess parts 44 disposed around the circular projectingpart 43 within therecess part 42 are formed on a face, opposing the first case membermain portion 27a of thefirst case member 27, of the other end part of the magnet keymain body 40 in a state in which the magnet keymain body 40 is stored in thestorage recess part 30. In a state in which themagnets 41 are housed in threehousing recess parts 44 selected from the fourhousing recess parts 44 so that one of the N pole and the S pole faces the outer end of thehousing recess part 44, alid member 46 having in its central part acircular hole 45 having the circular projectingpart 43 fitted thereinto is fitted into therecess part 42 and glued, thus forming themagnet key 22. - Moreover, in order to achieve a constant attitude of the
magnet key 22 when inserted into the magnetkey insertion hole 21 of themagnet lock 20, aninclined face 40a is formed on each of opposite sides in the width direction of a face, on the opposite side to the face on which themagnets 41 are disposed, of the magnet keymain body 40. The magnetkey insertion hole 21 is also formed into a shape corresponding to the cross-sectional shape of the magnet keymain body 40. - The
key unit 25 includes, in addition to themagnet key 22, thecase 23, and themechanical key 24, atorsion spring 48 as an elastic member elastically urging themagnet key 22 toward the projecting position, anoperation restriction member 49 restricting operation of themagnet key 22, and apush button 50 disposed on thecase 23 so that it can operate theoperation restriction member 49. - Referring in addition to
FIG. 6 to FIG. 12 , a circular springhousing recess part 51 is formed in one end part of the first case membermain portion 27a of thefirst case member 27, a rod-shaped projectingportion 27j being projectingly provided in a central part of the circular springhousing recess part 51, and a cylindricalguide tube portion 27k projecting from the peripheral edge of the springhousing recess part 51 toward thesecond case member 28 side being provided integrally with the one end part of the first case membermain portion 27a. Furthermore, an arc-shapedpivoting restriction groove 52 disposed around theguide tube portion 27k is formed in the first case membermain portion 27a. - The
operation restriction member 49 integrally includes acylindrical portion 49a having one end part inserted into theguide tube portion 27k, a pair of firstengagement arm portions 49b projecting toward opposite sides from the outer periphery of thecylindrical portion 49a so as to be disposed on one diameter of thecylindrical portion 49a, and a pair of secondengagement arm portions 49c projecting toward opposite sides from the outer periphery of thecylindrical portion 49a so as to be disposed on another diameter of thecylindrical portion 49a closer to the first case membermain portion 27a than the firstengagement arm portions 49b, the firstengagement arm portions 49b and the secondengagement arm portions 49c projecting from thecylindrical portion 49a so as to extend in directions orthogonal to each other. Furthermore thepush button 50, which is formed into a bottomed cylindrical shape, is coaxially and connectedly provided integrally with the other end part of thecylindrical portion 49a. - One end part of the
torsion spring 48 is housed within the springhousing recess part 51 so as to surround the projectingportion 27j of thefirst case member 27 and abuts against the first case membermain portion 27a. The other end part of thetorsion spring 48 is housed within thepush button 50 and abuts against thepush button 50. Moreover, afirst engagement piece 48a formed on the one end part of thetorsion spring 48 engages with a latchinggroove 58 formed in thefirst case member 27 so as to transect one location in the peripheral direction of theguide tube portion 27k, and asecond engagement piece 48b formed on the other end part of thetorsion spring 48 engages with alatching projecting portion 50a formed in the interior of thepush button 50. Due to such atorsion spring 48 theoperation restriction member 49 and thepush button 50 are spring-biased in a direction away from the first case membermain portion 27a and are spring-biased in the clockwise direction inFIG. 6 andFIG. 10 toFIG. 12 . - A through
hole 53 is provided in one end part of the magnet keymain body 40 of themagnet key 22 so that part of theguide tube portion 27k of thefirst case member 27 is inserted into the throughhole 53, thecylindrical portion 49a of theoperation restriction member 49 extending through the throughhole 53. Aninsertion hole 54 having a smaller diameter than that of the throughhole 53 is provided in one end part of the second case membermain portion 48a of thesecond case member 28 coaxially with the throughhole 53 so that thecylindrical portion 49a of theoperation restriction member 49 and thepush button 50 are inserted through theinsertion hole 54. - A pair of
fitting grooves 55 are provided in the magnet keymain body 40 so as to open on an inner face of the throughhole 53 and extend in the axial direction, the firstengagement arm portion 49b of theoperation restriction member 49 being slidably fitted into thefitting groove 55. On the other hand, a pair of firstengagement recess parts 56 forming astep portion 56a opposing, from the side opposite to the magnet keymain body 40, the firstengagement arm portion 49b of theoperation restriction member 49 urged in the axial direction by means of thetorsion spring 48 are provided in the second case membermain portion 28a of thesecond case member 28, the firstengagement recess parts 56 opening on an inner face of theinsertion hole 54 and toward the magnet keymain body 40 side while communicating with thefitting groove 55 in a state in which themagnet key 22 is in the storage position. - Furthermore, a pair of second
engagement recess parts 57 forming astep portion 57a capable of abutting, from the side opposite to the first case membermain portion 27a, against the secondengagement arm portion 49c of theoperation restriction member 49 urged in the axial direction by means of thetorsion spring 48 are provided in the magnet keymain body 40, the secondengagement recess part 57 opening on an inner face of the throughhole 53 and toward the first case membermain portion 27a. The secondengagement arm portions 49c of theoperation restriction member 49 are slidably engaged with the secondengagement recess parts 57. - Due to the first
engagement arm portion 49b of theoperation restriction member 49 being fitted into thefitting groove 55 of the magnet keymain body 40 and the secondengagement arm portion 49c being engaged with the secondengagement recess part 57 of the magnet keymain body 40, the magnet keymain body 40 is elastically urged toward the projecting position side by means of the spring force of thetorsion spring 48 acting on theoperation restriction member 49. When themagnet key 22 is pivoted to the storage position against the spring force of thetorsion spring 48, thefitting groove 55 of the magnet keymain body 40 is made to communicate with the firstengagement recess part 56 of thesecond case member 28, and theoperation restriction member 49 urged in the axial direction by means of thetorsion spring 48 moves in the axial direction to a position in which part of the firstengagement arm portion 49b is engaged with the firstengagement recess part 56. This makes the firstengagement arm portion 49b engage while straddling thefitting groove 55 and the firstengagement recess part 56, and themagnet key 22 is held at the storage position even when themagnet key 22 leaves the hand. In this arrangement, the secondengagement arm portion 49c of theoperation restriction member 49 abuts against thestep portion 57a of the secondengagement recess part 57, the magnet keymain body 40 is pushed toward thesecond case member 28 side by means of the axial spring-biasing force of thetorsion spring 48, rattling of themagnet key 22 within thecase 23 is suppressed, and in this state part of thepush button 50 projects from the second case membermain portion 28a of thesecond case member 28. - That is, the
operation restriction member 49 is disposed in thecase 23 so as to operate between a restriction position in which it is engaged so as to straddle thefitting groove 55 and the firstengagement recess part 56 when themagnet key 22 is at the storage position, thus holding themagnet key 22 at the storage position (position shown by solid line inFIG. 7 andFIG. 8 ) and a restriction release position in which thepush button 50 is pushed in so as to release the engagement with theengagement recess part 56, thus allowing themagnet key 22 to pivot from the storage position to the projecting position (position shown by chain line inFIG. 7 andFIG. 8 ). - Furthermore, a
restriction projecting portion 40b is projectingly provided integrally with the magnet keymain body 40, therestriction projecting portion 40b being fitted into the pivotingrestriction groove 52 formed in the first case membermain portion 27a of thefirst case member 27, and due to therestriction projecting portion 40b abutting against opposite ends in the peripheral direction of the pivotingrestriction groove 52 the end of pivoting of themagnet key 22 toward the storage position side and the end of pivoting thereof toward the projecting position side are restricted. - The operation of this embodiment is now explained; in the
key unit 25 having themagnet key 22 that can unlock themagnet lock 20, since themagnet key 22 is mounted on theportable case 23 so that it can operate between the projecting position in which it projects from thecase 23 and the storage position in which it is stored in thecase 23, it is possible to enhance the degree of freedom in the design of thekey unit 25. - Furthermore, since the
key unit 25 includes thetorsion spring 48 elastically urging themagnet key 22 toward the projecting position, theoperation restriction member 49 supported on thecase 23 so that it can operate between the restriction position in which themagnet key 22 is held at the storage position and the restriction release position in which themagnet key 22 is allowed to operate from the storage position to the projecting position and being elastically urged toward the restriction position side, and thepush button 50 disposed on thecase 23 so that it can be pushed in so as to forcibly move theoperation restriction member 49 to the restriction release position, it is possible, by merely pushing in thepush button 50, to move the magnet key 22 from the storage position to the projecting position, thus improving the ease of operation. - Moreover, since the
magnet key 22 unlocks themagnet lock 20 holding theshutter plate 19 at the closed position, theshutter plate 19 opening and closing thekey hole 18 of thecylinder lock 15, it is possible to enhance the ease of opening of theshutter plate 19 protecting thekey hole 18 of thecylinder lock 15. - Furthermore, since the mechanical key 24 unlocking the
cylinder lock 15 is fixed to thecase 23 so as to project from thecase 23, it is possible to enhance the portability of thecase 23. - An embodiment of the present invention is explained above, but the present invention is not limited to the above embodiment and may be modified in a variety of ways as long as the modifications do not depart from the spirit and scope thereof.
- For example, in the above embodiment the
torsion spring 48 elastically urges themagnet key 22 toward the projecting position and urges elastically urges theoperation restriction member 49 toward the restriction position side, but a first elastic member elastically urging themagnet key 22 toward the projecting position and a second elastic member elastically urging theoperation restriction member 49 toward the restriction position side may be provided.
