Definitions

  • This invention relates to a mechanism for latching a movable member to a fixed member; more particularly, it relates to a door latch for an automobile.
  • a bolt In a typical automobile door latch, a bolt is moved in response to closing of the door and a detent coacts with a ratchet tooth on the bolt to prevent return movement of the latter.
  • Means are also provided to lock the door in its closed or latched position. These locking means may typically comprise a key cylinder lock on the outside of the door and a push button or locking handle on the inside of the door.
  • latches today are of the safety type in which two ratchet teeth are provided serially on the bolt so that if the detent shakes loose from one tooth, as for example in an accident, it may still be engaged by the second or safety tooth to prevent opening of the door.
  • the appropriate key when inserted in the key cylinder lock associated with the latch will readily turn to lock the door. Since the fact that the door is in its safety rather than its fully latched position is not readily sensed, either visually or tactually, and since the key turns readily in the key cylinder to lock the door, the operator may leave his car thinking it to be securely locked when in fact the door is only in its safety position. In this condition, the car may be readily entered since a moderate inward 'push on the door trips the locking mechanism and unlocks the door.
  • Another object is to provide an improved latching mechanism for an automobile door.
  • a more specific object is to provide an automobile door latch of the safety type which cannot be locked with the door in its safety position.
  • a yet more specific object is to provide a safety type automobile door latch, including a key cylinder lock, in which a key inserted in the lock cannot be turned with the door in its safety position.
  • Another object is to provide a safety type automobile door latch, including an inside locking mechanism such for example as a push button, in which the inside locking mechanism cannot be moved to its locking position with the door in its safety position.
  • an inside locking mechanism such for example as a push button
  • the door latch includes means which sense the position of the detent means and operate to prevent operation of the various locking devices when the detent means is sensed to be in its safety rather than its fully latched position.
  • detents cludes two separate detents. These detents are arranged so that, as the bolt is moved in response to closing of the door, the first or safety detent moves from its rest position into a position of coaction with the safety tooth on the bolt whereafter, with continued movement of the bolt, the second or fully latched detent moves from its rest position into a position of coaction with the fully latched tooth on the bolt.
  • a locking member is provided which, when moved into its operative position as by depression of the inside push button or turning of a key in the key lock cylinder, locks the detents in their latching position so that manipulation of the outside or inside door handles will be ineffective to release the detents.
  • This locking member when moving between its rest and operative positions, 'follows a path which is blocked by a portion of the second or fully latched detent with the latter in its rest position.
  • neither the inside push button nor the key lock cylinder will be effective to lock the door since the locking member will be prevented from moving to its locking position by the second or fully latched detent lying across its path.
  • FIGURE 1 is a fragmentary view of an automobile with the right front door shown in an open position to reveal the mounting in the door of a door latch constructed according to the present invention
  • FIGURE 2 is a fragmentary side elevational view on an enlarged scale of the door latch of FIGURE 1 showing the latch in its unlatched or rest position;
  • FIGURE 3 is a view similar to FIGURE 2 but showing the latch in its partially latched or safety position;
  • FIGURE 4 is a view similar to FIGURES 2 and 3 but showing the latch in its fully latched position
  • FIGURE 5 is an end elevational view of the latch of FIGURES 1 to 4.
  • the latch of the invention broadly considered, comprises a striker 10 rigidly extending from door post 12 and an assembly 14 mounted within door 16 and exposed, by a tapered slot 18 in door panel 19, for coaction with striker 10 upon closing of the door.
  • Striker 10 includes a cylindrical shank portion 20 and a cylindrical flange portion 22.
  • door assembly 14 includes a bolt or rotor 24 mounted for pivotal movement on 'a' pin 26 secured to the latch frame.
  • Bolt or rotor 24 is shaped to define a latch arm 28 and a throw- As door 16 is closed, shank portion 20 of striker 10 is out arm 30 defining therebetween a slot or throat 32. guided by slot 18 into engagement with throwout arm 30, whereby to pivot rotor 24 about the axis of pin 26 and move latch arm 28 around shank portion 20, as seen in FIGURES 3 and 4, to trap shank portion within throat 32.
  • a spring (not shown) resists such pivotal movement of rotor 24.
  • Rotor or bolt 24 includes a first or safety tooth 36 and a second or fully latched tooth 38. Teeth 36, 38 respectively present substantially radial tooth faces 40, 42 for coaction with first and second detents 44, 46. Upon rotation of rotor 24 in response to closing of door 16, detent 44 is moved into the trace of face 40, whereby to block return rotation of rotor 24, and thereafter detent 46 is moved into the trace of face 42, whereby to further block return rotation of rotor 24.
  • rotor 24 is a laminated structure comprised of two plates 48 and 50 held in face to face relation as by rivets 52.
  • Plate 48 the foremost plate as viewed in FIGURES 2 to 4, in addition to providing the above-described arms 28 and and throat 32, also provides radial face 42.
  • Plate 50 the rearmost plate as viewed in FIGURES 2 to 4 provides radial face 40. Faces 40 and 42 are thus disposed in different planes so that detents 44 and 46 may pivot side by side about a common pin 54 secured to the latch frame.
  • follower arm 43 of detent 44 is urged by a spring (not shown) against a follower surface 60 provided by an arcuate peripheral portion of plate adjoining face 40
  • follower arm 45 of detent 46 is urged by a spring (not shown) against a follower surface 64 provided by an arcuate peripheral portion of plate 48 adjoining face 42.
  • follower arm 43 After a predetermined amount of further angular movement of rotor 24, during which time follower arm 43 moves to a position spaced circumferentially from face 40, follower arm 45 runs off of surface 64 and is moved by its spring into the trace of face 42 where it coacts with that face to latch the rotor and prevent return rotation of the latter.
  • FIGURE 4 This fully latched condition of the rotor is shown in FIGURE 4.
  • the detent arm 43 since it has been moved well beyond face 40, cannot be hung up on that face but rather must of necessity be firmly planted in the peripheral trace of that face.
  • arm 45 should hang up on face 42 upon closing of the door and thereafter be shaken loose from that tooth to release rotor 24, the rotor will be positively caught by the subsequent firm abutment of the butt end of detent arm 43 against face 40.
  • Each detent 44, 46 includes a radial brake arm 72, 73.
  • a pad 74 formed of any suitable cushioning material such for example as sponge rubber, is suitably secured to the latch frame in a position in the path of pivotal movement of brake arms 72, 73.
  • brake arm 72 is moved against cushion 74 to prevent arm 43 from slapping noisily against the adjacent underlying peripheral surface 76 of rotor plate 50.
  • brake arm 73 is moved against cushion 74 to prevent arm 45 from slapping noisily against the adjacent underlying peripheral surface 78 of plate 48.
  • Rotor 24 may be released for movement from its fully latched position of FIGURE 4 to the unlatched position of FIGURE 2 either by depression of the usual outside door handle push button 80 or by operation of the usual inside door handle (not shown).
  • Depression of push button 80 pivots a bell crank 82 about a fixed pivot pin 83 to depress a rod 84.
  • Rod 84 is pivotally connected at its upper end to crank 82 and at its lower end to a T-shaped lever 85 pivotally mounted on pin 54 behind detents 44, 46.
  • Lever 85 is connected by a screw 86 to one arm 87 of a three-armed lever 88 pivoted on pin 54 behind lever 85.
  • Another arm 89 of lever 88 carries a tab 90 for coaction with tabs 91, 92 carried on brake arms 72, 73 of detents 44, 46.
  • button 80 As button 80 is initially depressed, rod 84 is depressed to pivot levers 85, 88 clockwise about the axis of pin 54 and bring tab 90 into engagement with tabs 91, 92. Further depression of button 80 causes tab 90 to pick up tabs 91, 92 and thereby pivot detents 44, 46 clockwise about the axis of pin 54 and lift follower arms 43, 45 clear of radial faces 40, 42 to allow the door to be opened.
  • a slot 93 in lever 85 coacts with screw 86 to allow the relative angular position of levers 85, 88 to be adjusted to achieve the desired amount of free play in the outside door handle release linkage.
  • Means are also provided to lock the door in its latched position. These means include a locking lever 100 pivotally mounted on pin 26 behind rotor 24. One end of lever 100 is forked to provide arms 102, 104 and each such arm has its free end bent over to form tabs 106, 108, respectively. Lever 100 is movable between an unlocked position, as seen in FIGURES 2 and 3, and a locked position, as seen in FIGURE 4.
  • lever 100 With lever 100 in its locked position, tab 106 on arm 102 lies in the arcuate path of the tip end of an arm 110 formed as an integral part of lever 88 and tab 108 on arm 104 lies in the arcuate path of the tip end of an arm 111 formed as an integral part of detent 46.
  • Lever 100 is thus operative to render the outside door handle release means inoperative to release the detents, since as push button 80 is depressed, arm 110 on lever '88 is quickly rotated into abutment with tab 106 on locking lever 110 to block further releasing movement of the outside door handle release assembly.
  • the inside release mechanism overrides the locking lever so that, as is customary with a front automobile door, the door may be opened by the inside door handle even though the door is locked.
  • locking lever 100 With locking lever 100 in its unlocked position as seen in FIGURES 2 and 3, tab 106 lies below the arcuate path of the tip end of arm 110 and tab 108 lies below the arcuate path of the tip end of arm 111 so that the detents may be released by actuation of either the outside or the inside door handle.
  • the locking lever 100 may be moved to its locked position by actuation of the usual push button 115 projecting upwardly above garnish molding 116 or by actuation of the usual key cylinder lock 117.
  • Push button 115 connects to one end of lever 100 by a rod 118 so that depression of push button 115 pivots lever 100 counterclockwise to its locked position and raising of push button 115 pivots lever 100 clockwise to its unlocked position.
  • the push button is shown in its raised or unlocked position in FIGURES 2 and 3 and in its depressed or locked position in FIGURE 4.
  • a rod 120 connects the other end of lever 100 to the free end of the crank arm 122 of lock 117.
  • crank arm 122 is pivoted upwardly to pivot lever 100 counterclockwise to its locked position; turning of the key in the opposite direction pivots crank arm downwardly to pivot lever 100 clockwise to its unlocked position.
  • An overcenter spring 126 enables locking lever 100 to move with a snap action between its locked and unlocked position and maintains the locking lever in the position to which it is moved by the push button or by the key cylinder lock.
  • the locking lever cannot be moved into its aforesaid locked position by either the push button or the key cylinder lock unless the door is in its fully latched position since, with detent 46 in its rest or unlatched position, the tip end of arm 111 lies in the arcuate path of tab 108 on locking lever 100.
  • the tab 108 will move quickly into abutment with the tip end of arm 111 to block movement of lever 100 into its locked position.
  • abutment of tab 108 with arm 111 will block movement of lever 100. In either case, the operator, having attempted and failed to lock the door, will be thereby apprised that the door is in its safety rather than its fully latched position.
