  • the doortailgate 11 is shown in a partially opened condition as it would appear when swung about a vertical hinge in con- Ventional door-like fashion.
  • the end face 12 of the door has mounted thereon an upper latch mechanism 13 and a lower latch mechanism 14. These latch mechanisms are engageable with striker devices 15 each of which comprises a mounting plate 16 and a striker or keeper pin 17.
  • the present disclosure is concerned with the latch mechanism 13 which functions not only as a latch mechanism but also as a means for controlling the manner in which the door-talgate 11 is operated, i.e. eithel as a door swingable about a vertical hinge axis or a tailgate swingable about a horizontal hnge axis.
  • Upper latch mechanism 13 comprises a main plate 18 adapted to be secured as by means of screws (mot shown) to the inner face of the free edge or jarnb opposing wall 12 of the door-tailgate 11.
  • the main plate 18 has a flange or second plate 19 which is adapted to be positioned along the inner panel of the door.
  • the latch mechanism 13 has a single pivoted latch device means comprisng a jaw element 21 positioned at the outer face of the main plate 18.
  • the jaw element 21 is provided with a shaft or pivot portion 22 havng a re Jerusalem hearing portion 23 extending through a suitable flanged aperture in the main plate 18.
  • the inner reduced end or hearing portion 23 on each shait 22 is provided with diammetrcally opposed flats 24 thereon. Fitted over the hearing portion 23 and keyed thereto by the flats 24 is a control plate 25.
  • the jaw element 21 is thus rigidly coupled to the control plate 25, being concentric there- 3 with on the shaft 22.
  • the latch device means thus comprises a jaw element 21, shaft 22 and con trol plate 25.
  • the jaw element 21 is a substantially triangular plate member having its pivot axis located near its apex and having two depending finger-like portions 26 and 27 sepa rated by a semi-circular recess or enlarged notch 28,
  • the control plate is a substantially circular member having a cam appendage 29 at one side. At its lower edge, as viewed in FIG. 2, the cam appendage 29 terminates in a straight edge portion 31.
  • the periphery of the cam appendage is identified as 32, for a reason to be hereinafter explained.
  • a spiral spring 33 is disposed concentrically with and adjacent the inner face of the control plate 25.
  • the spring 33 is coupled at the center end of the shaft 22, the shaft having a slot or kerf receiving the spring at its inner end 34.
  • the outer or free end 35 of the spring 33 is looped over the edge of a projection 36 and the upper edge of the main plate 18.
  • the spring 33 is installed in a preloaded condition so that it at all times tends to rotate or urge the control plate 25, the shaft 22 and associated jaw element 21 in a clockwise direction, as viewed in FIG. 2.
  • the straight edge 31 of the cam appendage 29 of the control plate 25 is adapted to cooperate with an abutment 37 carried on a detent means, generally designated 38.
  • a detent means generally designated 38.
  • the detent means 38 is pivotally mounted on the main plate 18 by means of a pivot stud 39 and is urged in a clockwise direction or toward the control plate 25 by a spiral spring 41.
  • the spring 41 is anchored at its inner end 42 to the pivot stud 39 and its free 01 outer end 43 to a short upwardly extending projection 44 of the detent means 38. It will be apparent from FIG. 2 that the detent means 38 must be swung in a clockwise direction about its pivot 39 to permit movement of the control plate 25 and thereby the jaw element 21 in unlatching direction. That is, the abutment 37 on the detent means 38 must be moved out of the path of the edge 31 of the cam appendage 29 on the control plate 25.
  • Disengaging movement of the detent means 38 from the control plate 25 is accomplished in the latch mechanism embodying the present invention through a system of levers adapted to be operated from the outside or the inside of the vehicle door.
  • the detent means 38 is provided with a substantially horizontally extending arm 45 and a shorted upwardly angularly inclined arm 46.

  • the bell crank lever 48 is pivotally mounted at 52 to the flange 19 and is spring loaded by a spiral spring 53 so that a hook portion 54 on the upper end of the arm 49 is always being urged in the direction to overle the extenson of the detent arm 45.
  • the spiral spring 53 urges the bell crank 48 in a clockwise direction, or, as viewed in FIG. 4, the direction is counterclockwise.
  • the bell crank lever 48 is the latch mechanism locking lever.
  • the bell crank lever 48 is coupled to an operating or control rod 55, and it will be obvious that any downward movement of the rod 55 will pull the bell crank lever 48 against the resistance of the spring 53 out of the path of the detent means arm 45 so that the latter may rise upwardly in the slot 47.
  • the rod 55 extends downwardly in a substantially vertical direction within the door 11.
  • the door as are most station wagon doors, is provided with a window (not visible) whch may be raised or lowered into the window well formed by the panels of the door.
  • a window not visible
  • the window When the window is raised the framed edges of the window fit within guide channels in the upper half of the vehicle body and the door cannot be opened, either as a tailgate or as 21 door, until the window is lowered into the well.
  • downward movement of the window into the well results in the bottom edge of the window frame engaging a projection on the rod 55 pulling the latter downwardly. This downward movement results in the bell crank lever 48 hook portion 54 being swung out of blocking position relative to the detent means arm 45.
  • rod 55 might be coupled to a key cylinder operated lever or other suitable device for moving and holding the rod 55 in a down position so that the bell crank lever 48 is swung and held in a neutral or non-blocking position relative to the detent means arm 45.
  • the latch mechanism may be actuated from either the outside or the inside of the door 11.
  • a turnable handle 56 (see FIG. 1) is shown mounted on the outer panel of the door 11.

  • the actuating means comprises a pair of levers 58 and 59, respectively, swingable about a common pivot 61.
  • the lever 58 At its outer end 62 (as seen in FIG. 2) the lever 58 is provided with a shelf portion 62a adapted to receive the cam end of the handle 56.
  • the lever 58 is provided with a flange 63 and a lug 64 vertically spaced above the flange 63.
  • the lever 59 is swingable about a common pivot 61 with the lever 58.
  • the lever 59 is pivoted at one end on the pivot 61 and extends towards the flange 19 of the main plate 18.
  • the lever 59 has an end portion 65 whch projects through a slot 66 in the flange 19.
  • the slot 66 functions as a guide to ensure that the lever 59 moves in a substantially consistent path relative to the plane of the flange 19 as it swings up and down about its pivot 61.
  • the lever 59 has an upstanding arm 67 whch terminates in a short flange 68 adapted to abut the arm 46 of the detent means 38 upon the lever 59 being swung in a clockwise direction as viewed in FIG. 2.
  • the lever 59 also is provided with a flange 69 along its upper edge to the right of the upstanding arm 67.
  • a compression spring 71 is positioned between the lever 59 flange '69 and the lever 58 flange 63.
  • the compression spring 71 is a stiff spring.
  • the insde operator or second actuating means is represented as a rod 72 which extends to a remote handle located on the inner panel of the tailgate (at about its midpoint).
  • the rod 72 is coupled to the upper arm 73 of a bell crank generally designated 74.
  • the bell crank 74 has a depending arm 75 which carries a rod 76 which is guided at its tree end by a projection or guide lug 77 on the flange 19, the projecton 77 being provided with a suitable aperture through which the rod passes.

  • the arm 45 wil] lie in the path of the hook end 81 of the bell crank arm 74 and the latter will remain blocked against rotation in a counterclockwise direction and thereby block movemeut of rod 72.
  • the lever 59 is provided with an aperture 82 which is adapted to receive a rod 83.
  • the rod 83 extends to the lower latch mechanism 14 and transmits movement of the lever 59 to a corresponding lever in the lower latch mechanism 14. Ths causes the lower latch mechanism to be simultaneously released with the upper latch mechanism permitting the door to be swung open as shown in FIG. 1.
  • the rod 72 and the bell crank lever 74 to which it is coupled may be considered the inside operator for actuating the present latch mechanism.
  • the inside operator is actuated when it is desired to swing the door 11 about a horizontal hinge axis so that it will function as a conventional tailgate.
  • the arm 79 of the bell crank lever 74 underlies the arm 45 of the detent means.
  • the detent means may be disengaged from the latch device means by swing ing the bell crank lever 74 in a counterclockwise direction thereby lifting the arm 79 into abutting relation with the arm 45 of the detent means 38.
  • the detent means will be then swung in a clockwise direction causing disengage ment of the projection 37 from the edge 31 of the cam appendage 29 of the control plate 25.
  • the parts of the latch mechanism will then assume the positions shown in FIGS. 7 and 8.
  • the detent means 38 will remain at a tilted angle relative to its initial position shown in FIG. 2 because of the interference between the periphery 32 of the cam appendage 29 and the projection 37 051 the detent means.
  • the rod 76 which is coupled to the lower arm 75 of the bell crank lever 74 is projected into the path of the extension 65 of the lever 59, sec FIG. 8.
  • the lever 59 is thus rendered inoperative to transmit any motion to the lower latch mechanism 14 through the connecting rod 83.
  • the lower latch mechanism must be maintained in latched condition relative to the lower striker pin 17 and in this latched position it is capable of functioning as a hinge element which with the multi-hinge mechanism (not shown) anchoring the other end of the door to the vehicle body forms the horizontal hinge axis about which the door is swingable as a tailgate.
  • the outside handle 56 can be actuated but al] that will result from such actuation will be a compression of. the spring 71 as the lever 58 is moved in la clockwise direction. Upon release of the outside handle, the parts will spring back to the position shown in FIGS. 2 and 7.
  • the bell crank lever 74 cannot be restored to its inoperative position, as will be apparent from FIG. 8.
  • the hook-like porton 81 of the arm 79 of the bell crank lever 74 overlies the detent arm 45, the detent arm beng maintained in an upwardly angularly inclined postion relative to its normal position because of the interference between the periphery 32 of the cam appendage 39 and the projection 37 on the detent means. It is only when the door is slammed shut and the detent abutment 37 drops into abutting relationship to the straight edge 31 on the cam appendage 29 that the inside operated bell crank lever 74 can be restored to its FIG. 3 position.
