  • the conventional door locking and unlocking apparatus includes a pair of front and rear latch units 103 having latches engaged with strikers of a vehicle body for maintaining a vehicular door in a closed state relative to the vehicle body, handle units 106 and 107 on an inner side and an outer side of the vehicular door for operating the latch units 103 to bring the door into an opened state or a closed state relative to the vehicle body, and a remote control unit 104 for making operation of the handle units 106 and 107 transmittable or nontransmittable to the latch units 103.
  • the latch units 103 each is constituted by a structure having a rotatable latch engaging to and disengaging from the striker of the vehicle body, a rotatable pawl engaged with the latch for restricting rotation of the latch and a main lever for operating the pawl.
  • the remote control unit 104 is constituted by a structure having an open lever connected and engaged with the handle units 106 and 107, a lift lever connected and engaged with the latch units 103 and capable of engaging to and disengaging from the open lever and a locking lever engaging to and disengaging from the open lever and the lift lever.
  • unlatch operation of the latch units 103 is carried out by operating main levers of the latch units 103 via the open lever and the lift lever of the remote control unit 104 by operating the handle unit 106 and 107.
  • lock operation of the latch units 103 is carried out by releasing engagement of the open lever and the lift lever of the remote control unit 104 by operating the locking lever of the remote control unit 104 by operating a sill knob provided on the compartment inner side of the vehicular door or a key cylinder provided on the compartment outer side.
  • the lift lever of the remote control unit 104 and the main levers of the latch units 103 are coupled by cables and rods arranged in the vehicular door, and thereby the remote control unit 104 and the latch units 103 are connected and engaged with each other.
  • the latch units are operated to unlock by operating the remote control unit, as a result, the unlatch operation of the latch units can be carried out by operating the handle units and there is the danger of opening the door.
  • a slide door 101 of a vehicle is arranged with the pair of front and rear latch units 103 for maintaining a slide door 101 in a closed state relative to a vehicle body 102 and a remote control unit 104 for operating the latch units 103.
  • the remote control unit 104 and the pair of front and rear latch units 103 are connected and engaged with each other by cables and rods arranged to the slide door 101, further, the remote control unit 104 is connected and engaged with a outside handle unit 107 arranged on a panel of the compartment outer side of the slide door 101 and the inside handle unit 106 arranged on a panel of the compartment inner side of the slide door 101.
  • the remote control unit 104 is mainly constituted by a lift lever 41, an inside open lever 42 and an outside open lever 43.
  • the lift lever 41 is pivotably supported by a coaxial shaft 93 at a central portion in the longitudinal direction thereof and coupled to sublevers 4 of the latch units 103, mentioned later, by cables 11 at both ends thereof.
  • a slide bush 47 is slidably supported by the lift lever 41.
  • the inside open lever 42 is pivotably supported by the coaxial shaft 93 provided at a base bracket 91 and is connected to an inside handle of the inside handle unit 106 via a rod 61a at one end thereof.
  • a slide bush 48 is slidably supported.
  • the outside open lever 43 is pivotably supported by the coaxial shaft 93 at one end thereof and is connected to an outside handle of the outside handle unit 107 via a cable 43e at other end thereof.
  • the outside open lever 43 is engageably and disengageably arranged with engaging and disengaging pin portions 47a and 48a of the slide bushes 47 and 48.
  • the slide bush 47 is made to slide by a locking lever 44.
  • the locking lever 44 is pivotably supported by the base bracket 91 by snap engagement and is inserted with a connecting pin portion 47b of the slide bush 47.
  • the locking lever 44 is connected to an output lever 51 of a locking actuator 50 attached to the base bracket 91. Further, the output lever 51 is connected to a sill knob of the inside handle unit 106 via a rod 62a.
  • the slide bush 48 is made to slide by a connecting lever 49.
  • the connecting lever 49 is pivotably supported by the base bracket 91 by snap engagement and is inserted with the engaging and disengaging pin portion 48a of the slide bush 48.
  • the connecting lever 49 is connected to a child lever of the inside handle unit 106.
  • the latch unit 103 is mainly constituted by a main lever 3 and the sublever 4.
  • the main lever 3 is provided at its center portion with a hole 6 for inserting a pin 2 and at its one end with a long hole 7 extending longitudinally.
  • An end portion 8 of the main lever 3 on a side opposed to the end portion having the long hole 7 is capable of being brought into contact with an operating lever 9 connected to a pawl 18 of the latch unit 103.
  • the sublever 4 supported by the pin 2 is formed substantially in a T-like shape and is provided with a hole 10 for passing the pin 2, a piece 12 for fixing one end of the cable 11 and a contact piece 13 capable of being brought into contact with a second link 15, mentioned later.
  • first link 14 which is made pivotable by an output shaft of an actuator 5, is axially supported by one end of the second link 15.
  • the other end of the second link 15 is provided with a contact portion 16 capable of being brought into contact with the contact piece 13 of the sublever 4 and a projected portion 17 (or pin) inserted into the long hole 7.
  • bracket 1 is constituted by a box shape surrounding the main lever 3, the sublever 4, the first and the second links 14 and 15 and a portion of the actuator 5 to thereby prohibit unlawful approach to these parts from outside.
  • Fig. 2 shows a state for normal latch and unlatch operations.
  • the contact piece 13 of the sublever 4 is opposed to the contact portion 16 of the second link 15, the projected portion 17 is disposed at one end of the long hole 7 and the end portion 8 of the main lever 3 is opposed to the operating lever 9.
  • the operating lever 9 is coupled to the pawl 18 of the latch unit 103.
  • the pawl 18 is engaged with and disengaged from a ratchet 19 for receiving a striker on the vehicle body side and specifies positions of the ratchet 19 (latch and unlatch positions).
  • the actuator 5 In a lock state of the latch unit 103 by operating the locking lever 44 of the remote control unit 104, by an electric signal from an ignition key having an operating button for operating door lock apparatus of respective doors of the vehicle in wireless, an electric signal in cooperation with double lock operation of a door lock apparatus of a door on the driver's seat side or the like, the actuator 5 is operated and pivots the first link 14 in the counterclockwise direction of Fig. 2.
  • the first link 14 By pivoting the first link 14 in the counterclockwise direction of Fig. 2, as shown by Fig. 3, the projected portion 17 of the second link 15 is moved along the long hole 7 of the main lever 3 and the contact portion 16 is moved to a position separated from the contact piece 13 of the sublever 4 (double lock operation of latch unit 103).
  • the actuator 5 is operated and the first link 14 is pivoted in the counterclockwise direction of Fig. 3.
  • the second link 15 is moved along the long hole 7 and the normal state shown by Fig. 2 can be provided.
  • a spring may be arranged pertinently to maintain the state of Fig. 2.
  • the sublever 4, the actuator 5, the first and the second links 14 and 15, mentioned above, may be arranged to both or one of the pair of front and rear latch units 103.
