Claims

[Claims for Utility Model Registration] (1) The first member that pivots with respect to the second member 2
a driven member 60 adapted to be fixed to the pivot axis 3 of the member 1; a brake capable of preventing rotation of the driven member in a first direction in a first position and freeing the driven member in a second position; piece 50, and attached to the second member and attached to the tumbler body 4.
3, when the locking mechanism is in the locked state, the brake piece 50 is in the first position, and when the locking mechanism is in the unlocked state, the tumbler body 43 moves the brake piece 50 into the second position. A locking device 10 including a locking mechanism by which the tumbler body 43 can engage the brake piece 50 in such a way that it can be forced into position. (2) The lock device according to claim 1, further comprising a clutch mechanism provided between the brake piece 50 and the tumbler body 43. (3) In the locking device according to claim 2, the clutch mechanism includes a spring retainer 4 that slides on the tumbler body 43.
6, and a spring 47 having both ends attached respectively to the spring retainer and the brake shoe, when the tumbler body is not forced towards the brake shoe, the spring 4
7 includes a spring for disengaging the tumbler body from the brake shoe. (4) The lock device according to claim 1, further comprising a second lock device.
A locking device including a housing 20 secured to a member and housing the driven member 60, the brake piece 50 and the locking mechanism 40 therein. (5) The lock device according to claim 1, wherein the driven member includes a ratchet wheel 61. (6) A locking device according to claim 5, wherein said brake piece includes at least one pawl (54) capable of engaging said ratchet wheel (61). (7) The locking device according to claim 6, further comprising an intermediate piece 70 attached between the driven member 60 and the brake piece 50, when the locking mechanism is in the unlocked state and the first member is in the locked state. A locking device for causing the intermediate piece 70 to force the brake piece from the second position to the first position when pivoted into position in a first direction. (8) A locking device according to claim 7, wherein said driven member (60) further includes a gear (62) engageable with said intermediate piece (70). (9) The locking device according to claim 8, wherein the brake piece further includes a threaded shaft portion 563. (10) A lock device according to claim 9, wherein said intermediate piece (70) is a gear (72) having a threaded shaft hole (71) that engages with said threaded shaft portion (563).
