  As shown in FIGS. 13 and 14, the latch receiver A21 is protruded from a substantially frame-shaped claw receiving portion A211 having an engagement hole A2110 penetrating in the front-rear direction, and a lower end portion of the claw receiving portion A211. A pin-shaped latch claw protection part A212, a pair of support pieces A213 for projecting from both rear side edges of the claw receiving part A211 to support the latch receiver A21 on the door A2, and a rear upper end of the claw receiving part A211 And a fixing portion A214 for extending the latch receiver A21 to the door A2, and these portions are integrally formed of synthetic resin.

More specifically, the claw receiving portion A211 includes an upper piece A211a and a lower piece A211b, and a first connection piece A211c and a second connection piece A211d that connect both ends of the upper piece A211a and the lower piece A211b, respectively. From the first connection piece A211c to the second connection piece A so that the opening area of the engagement hole A2110 surrounded by the pieces A211a to A211d is reduced.
It includes an anchoring piece A211e extending toward 211d and capable of anchoring the latch claw 1. In the present embodiment, the taper portion A211x for guiding the elastic engagement with the latch claw element 11 is formed at the tip end portion of the anchoring piece A211e so as to be tapered.

  The latch claw protection portion A212 is provided at a position slightly inward of the claw receiving portion A211 before the mooring piece A211e, and is formed between the claw receiving portion A211 and the claw element support portion 12 with a slit width DD. (Refer FIG. 15) and a length dimension substantially equal. With this configuration, the gap SLx (see FIG. 15) near the pressed portion 11x of the latch claw element 11 can be closed with the latch claw protection portion A212 and the claw receiving portion A211.

  The support piece A213 is a thin plate having a substantially rectangular shape when viewed from the front, and in this embodiment, the height dimension is set to be approximately half the height dimension of the claw receiving portion A211.

  The fixing portion A214 includes a fixing portion main body piece A214a that is substantially rectangular in a front view standing from the upper end portion of the claw receiving portion A211 and a pair of bending pieces A214b that are bent from both side edges of the fixing portion main body piece A214a. A through-hole A214x for fixing the latch receiver 21 to the door A2 using a screw is formed in a substantially central portion of the fixing portion main body piece A214a. In the present embodiment, the height dimension of the fixing portion main body piece A214a is set so as to substantially match the height dimension of the claw receiving portion A211.

  The latch receiver A21 configured as described above is attached by using an upward substantially groove-shaped latch receiver attachment portion A21X provided at the lower end of the back side of the door A2. Specifically, the support piece A213 of the latch receiver A21 is arranged in the latch receiver mounting part A21X, and then screwed to the door A2 using the screw n inserted through the through hole A214x of the fixing part A214, thereby The latch receiver A21 is firmly fixed to the door A2.

  About the locking device Z comprised as mentioned above, the usage method is demonstrated concretely.

  First, when the door A2 in the open position is flap-operated to be positioned in the closed position, the rearward surface of the door A2 comes into contact with the push rod 41. When the door A2 is further flap-operated, the push rod 41 is brought into a position to be engaged with the engaging portion 511 of the link member 51 while being guided by the push guide portion 6Y while being pressed against the rearward surface of the door A2. Positioned (see FIGS. 9 and 10).

  Further, by this flap operation, the latch claw element 11 of the latch claw 1 is temporarily moved from the lock position (R1) to the unlock position (R2) by the pressing force from the latch receiver A21 while being in contact with the latch receiver A21 of the door A2. After the movement, it is positioned at the lock position (R1) that is elastically engaged with the latch receiver A21, and the opening of the door A2 is prohibited (see FIG. 10).

  Thus, when the actuator 3 is driven with respect to the latch claw 1 positioned at the lock position (R1), the engaging portion 511 of the link member 51 holds the push rod 41, thereby pushing the push rod 41. Therefore, the actuator 3 can be driven with a relatively small force, and the door A2 is re-constrained by the latch claw 1 that has returned the door A2 to the lock position (R1). It is possible to enter a re-constraint prevention state (S2) that prevents the occurrence (see FIG. 8).

  By the way, in the state where the opening of the door A2 is prohibited (see FIG. 15), the picking insert (not shown) is opened in the gap portion SL formed between the door A2 and the storage body A1. Even if it inserts from SL1, the insert is prevented from reaching the pressed contact portion 11x of the latch claw 1 by the latch claw protection portion A212 and the claw receiving portion A211. That is, it is possible to prevent the latch claw 1 from being moved from the lock position (R1) to the unlock position (R2) without depending on the actuator 3 due to the insert.

  In addition, without using the actuator 3, the locking part 8 can be used to hold the door A2 in the closed state (S1) or to open the door A2 in the closed state (S1).

  Specifically, for example, if the key K (see FIG. 1) is inserted and rotated in a key insertion port (not shown) and the actuator 82 is positioned at the locking position (P1), The locking piece 222b of the coupling body 22 of the reciprocating member 2 is locked, and the reciprocating motion of the reciprocating member 2 can be prohibited. That is, the door A2 can be held in the closed state (S1).

  Further, when the key K is inserted into the key insertion port and rotated to position the operating element 82 at the locking release position (P2), the locking piece 222b of the connecting body 22 of the operating element 82 and the reciprocating member 2 Is in the unlocked state, and the reciprocating motion of the reciprocating member 2 is allowed. That is, the door A2 in the closed state (S1) can be opened.

  Thus, according to the locking device Z according to the present embodiment, the latch claw protection part A212 prevents the insert from reaching the latch claw 1 even when the insert is inserted into the gap SL. Therefore, unauthorized opening of the door A2 due to picking can be prevented.

  That is, it is possible to provide the lock device Z having a high security function that can restrain the door A2 from being opened by picking the door A2 in the closed state (S1) while restraining the door A2 to the storage body A1.

  Since the latch claw protection part A212 extends in a direction crossing the gap SLx in the vicinity of the pressed part 11x, the latch claw 1 can be removed from the insert even though it has a very simple configuration. It can be effectively protected.

  The latch claw 1 has a pressed contact portion 11x that can be pushed in the unlocking direction by the insert when the latch claw protection portion A212 is not provided, and the latch claw protection portion A212 is close to the pressed contact portion 11x. Since it is provided at the position where it is placed, it is possible to save space and to reduce the cost.

  Since the latch claw protection part A212 is formed integrally with the latch receiver A21, it is effective for cost reduction by sharing the members.

  A plurality of latch claws 1 are held so as to be able to operate integrally, and a single reciprocating member 2 driven by an actuator 3 is provided, and a latch claw protection portion A212 is provided corresponding to each latch claw 1. As compared with the case where a link mechanism is used in place of the reciprocating member 2, the assembly accuracy is increased, so that the arrangement of the latch claw 1 and the latch claw protection part A212 can be easily adjusted.

  Since a plurality of latch claws 1 are held so as to be able to operate integrally and are provided with a single reciprocating member 2 driven by the actuator 3, and a common latch claw protection part A212 is provided for each latch claw 1, A high security function can be secured while realizing cost reduction.

  Since the latch claw 1 is elastically engaged with the latch receiver A21 provided on the door A2, it is not necessary to use a special member for the latch claw 1, and the configuration of the latch claw protection part A212 can be simplified. Therefore, cost reduction can be achieved.
