  • this will sequentially actuate the pushing member 33, the second cam disk 22b and the first cam disk 22a (as shown in FIG. 2B' ), and the rotation of the first cam disk 22a allows the drive member 21 to be turned by the control tab 220 (as shown in FIG. 2D ). Therefore, the drive member 21 can be controlled by the outdoor handle 8 (or the indoor handle 8') through the control structure 2a.
  • the user can move the actuating member 30 away from the control structure 2a using the target key 9 (in an actuating direction C' shown in FIG. 3A' ), so that the actuating portion 30b is moved back, and the toggle member 32 is turned back (in a rotating direction R' shown in FIG. 3A' ) as a result of the reciprocating movements of the spring 31.

Therefore, when the user rotates the passive member 34 via the control port 22, the passive member 34 can only move the second control column 221' towards the pushing direction B1, but cannot move the second cam disk 22b and the first cam disk 22a as the pushing member 33 is not linked.
  • the first cam disk 22a cannot move since the control tab 220 will not actuate the drive member 21, resulting in an idle-run state of the control structure 2a, in other words, the drive member 21 cannot be controlled by the outdoor handle 8 through the control structure 2a.
  • an idle-run mechanism of the control structure 2a is achieved with the arrangement of the pushing member 33 and the passive member 34. If this idle-run mechanism is not desired (such as in the case of the indoor handle 8'), then the toggle member 32 can be removed and the pushing member 33 can be permanently engaged with the passive member 34, i.e., the idle-run function is canceled.
  • the first cam disk 22a, the second cam disk 22b and the passive member 34 can be formed integrally (the first and second control columns 221 and 221' formed as one column) to eliminate the idle-run mechanism (such as in the case of the indoor handle 8').

  • the second active member 42 can be provided on the case body 1a in a displaceable manner so as to move the auxiliary bolt 12 along with it.
  • the second active member 42 is in the form of a rod body with one end secured to the auxiliary bolt 12, while the other end provided with at least one safety guide block 420.
  • At least one safety guide rail 108 in the form of a linear groove for engaging the safety guide block 420 is formed on the bottom face of the case body 1a (as shown in FIG. 4D ), so as to allow linear displacement of the second active member 42.
  • an arch wall 109 spanning over the second active member 42 is provided at the bottom face of the case body 1a, and the safety guide block 420 and the auxiliary bolt 12 are located at different sides of the fixed arch wall 109, wherein the second active member 42 is fitted with a safety spring 42a between the auxiliary bolt 12 and the fixed arch wall 109, and the two ends of the safety spring 42a can be secured to the auxiliary bolt 12 and the fixed arch wall 109, respectively, such that the second active member 42 passes through the fixed arch wall 109 for reciprocating movements in cooperation with the extension/contraction of the safety spring 42a.
  • the cam member 40 is in the form a strip that is pivotally connected to the bottom face of the case body 1a to release the first active member 41 or fix it in position.
  • one end of a pivot portion 400 of the cam member 40 is a fixating portion 401 that abuts between the safety guide block 420 of the second active member 42 and the fixed arch wall 109, and the other end of the pivot portion 400 of the cam member 40 is a hook portion 402.
  • the pivot portion 400 of the cam member 40 is provided with a safety torsional spring 40a with one end secured by a stand 43 of the hook portion 402 and the other end attached to a fixating rod 109' on the bottom face of the case body 1a, such that the cam member 40 generates reciprocating movements through the torque of the safety torsional spring 40a, such that the fixating portion 401 is actuated in cooperation with the second active member 42.
  • a pea-shaped drive stop block 213 is formed on the second arm 212 of the drive member 21, which abuts against the pivot portion 400 of the cam member 40 in order to actuate or stop the cam member 40.
  • the control tab 220 pushes the drive plate 211a and thus turns the drive member 21, so the second arm 212 of the drive member 21 pushes (indicated by the action direction F1 shown in FIGs. 2D and 4C ) the main guide column 200 and the auxiliary guide column 410, such that the corresponding column 412 follows the auxiliary guide column 410 and they move linearly along the auxiliary guides 107.
  • the fixating portion 401 of the cam member 40 will push the safety guide block 420 of the second active member 42 (in an action direction D shown in FIGs. 4C and 4E ) away from the fixed arch wall 109, so the safety guide block 420 moves linearly along the safety guide rail 108, such that the second active member 42 linearly moves the auxiliary bolt 12 along with it, so the auxiliary bolt 12 is retracted into the accommodating space S of the case body 1a.
  • the control structure 2a when the user releases the outdoor handle 8, the control structure 2a will return to its original position, but the drive member 21 will not be actuated (since the hook portion 402 is hooked to the auxiliary guide column 410, the first active member 41 is held in place, and the corresponding column 412 inhibits the return of the drive member 21). Therefore, the safety guide block 420 has to be moved (indicated by an action direction D' shown in FIG.
  • the restoring force of the drive member 21 i.e., the torque of the drive torsional spring 210a of the drive spindle 210) exerts a force (indicated by an action direction F4 shown in FIG. 4C and FIG. 4E ) on the corresponding column 412, such that the safety bolt 11 can spring out of the accommodating space S of the case body 1a as a result of the first active member 41.
  • the drive stop block 213 will abut with the pivot portion 400 of the cam member 40 to prevent the cam member 40 and its safety torsional spring 40a from moving.
  • the safety guide block 420 can be moved to actuate the second active member 42 and allow the cam member 40 to be unhooked, which actuates the drive member 21 to spring out the safety bolt 11 from the accommodating space S of the case body 1a.
  • the safety bolt 11 and the auxiliary bolt 12 can still be extended out of the accommodating space S of the case body 1a.
  • auxiliary bolt 12 and the second active member 42 can move independently of (i.e., not linked with) the outdoor handle 8 or the target key 9, when in a locked state (such as the state shown in FIG. 4A ), if the safety guide block 420 is manually moved via the safety guide rail 108 of the case body 1a, only the auxiliary bolt 12 will be moved back into the accommodating space S of the case body 1a, the cam member 40 will not be actuated to hook onto the auxiliary guide column 410 (since the fixating portion 401 is situated between the safety guide block 420 of the second active member 42 and the fixed arch wall 109), so the outdoor handle 8 (or the indoor handle 8') is still free to turn. This prevents the outdoor handle 8 (or the indoor handle 8') from locking and not operable during an emergency.
  • FIGs. 5A , 5B , 5C , 5D and 5E are schematic diagrams depicting a lock device 1 in accordance with a fourth embodiment of the present disclosure.

  • the regulating member 50 only needs to push the actuating portion 30b of the actuating member 30 out of the displacement path of the active member 20.
  • the actuating portion 30b only needs to be moved by a relatively short distance (not actuating the idle-run mechanism) unlike in the case of actuating the idle-run mechanism (as described with respect to FIGs. 3A to 3C ) where the actuating portion 30b is moved by target key 9 by a relatively longer distance.
  • the control structure 2a when the user releases the indoor handle 8', the control structure 2a returns to its original position, and the regulating member 50 is rotated back by the drive torsion spring 210a of the drive spindle 210, such that the stand 43 of the hook portion 402 is pushed by the regulating member 50 so as to push the hook portion 402 away from the auxiliary guide column 410 (refer to descriptions with respect to FIGs. 4A to 4E ).
