Definitions

  • the new lock is characterized by a self-cocking mechanism which is obtained by a new combination of a rocking bolt and a rocking tightening element, interacting between each other by a spring common to both the block and the tightening element and whose tension increases in relation with the closing movement of the door. This guarantees a more silent closure combined with an increased locking security because it is reached with the maximum tension of the spring.
  • Another advantage of the new lock consists of its compact arrangement.
  • FIG. 1 is an elevation view of the assembly of the lock mechanism and its keeper for a car door according to the invention
  • FIG. 2 is a sectional view along line A-A of FIG. 1;-
  • FIG. 3 is a rear view of the mechanism shown in FIG. 1;
  • FIG. 4 is a schematic view of the case of the lock according to FIG. 1 in which the holding plate is withdrawn while the keeper is shown, at the beginning of the closing movement of the door;
  • FIG. 5 is a similar view as in FIG. 4 in which the keeper is in its final closing position
  • FIG. 6 is a similar view as in FIG. 4, but shows the keeper in its intermediate position known as the security position;
  • FIG. 7 shows a similar view as in FIG. 4 according to a different embodiment but wherein the keeper is shown outside the rock mechanism;
  • FIG. 8 is a schematic view of some members of the mechanism illustrated in FIG. 7 and located behind the lock P
  • FIG. 9 is a schematic view similar to FIG. 7 but in which the keeper is in its intermediate position, that is, the security position;
  • FIG. 10 is a schematic view similar to FIG. 9 in which the keeper is in its final closing position
  • FIG. 1 l is a schematic view of .the mechanism members according to FIG. 10 which are located behind the lock plate at the beginning of the opening movement;
  • FIG. 12 is a schematic view according to FIG. 11 illustrating the end of the opening movement. 1
  • the lock mechanism for car doors consists of a usual bent plate 1, on which is mounted a raised case 2 an a U-shaped holding plate 3, allowing to house and support the bolt 4 of the lock which has the shape of a semicylindrical catch which is adapted to rock around its axis 5 as well as a tightening element'6 having the shape of a cam and having a hooking nose 7 adapted to rock around its axis 8 which appears eccentric due to the fact that its outer contour has the shape of spiral 9.
  • the internal outline of the holding plate 3 is reduced relative to the case 2 to allow the lateral'holding of the broad head 10 of the keeper, which inversely is raised by a crosspiece 11 and whose two upper notches 12 and 13 are adapted to suecessively grip the rocking bolt 4 while the lower notch 14 may grip the nose 7 of the cam 6.
  • the usual actuating lever 15 is mounted for operating the bolt 4 which is free to rock around its axis 5 while it is brought back against the bent abutment 16 of the plate I by a tension spring 17.
  • the actuating lever 15 comprises a bent leg 18 which while extending through the elongated aperture 19, of a-rocking sector 20, rigidly secured to the axis 5 of the bolt 4 constitute a resting abutment opposing the effect of the tension spring 21 which has abiasing effect on the leg 22 against the fixed abutment 23, while the counterclockwise rocking of the sector 20 according to FIG. 3 is obtained through a substantially well predetermined angle by the elongated aperture 19 and that another leg 24 can come to grip with leg 25 of a lever 26 having an angular shape, the said lever 26 being rigidly secured in rotation to the axis 8 of the cam 6 and which is also brought in a position of rest by the tension spring 21, the latter being connected at its other end on the sector 20.
  • FIG. 8 shows, for the position of the elements corresponding to FIG. 7, the orientation of the rock sector fixed on the axis 5' in that it coacts with the angular lever 26' fixed on the axis 8 to obtain a mutual balance, by the effect of the abutment 27 coming in contact with the rocking sector and with a minimum tension of their common spring 21'.
  • the tension of the spring 21' combined with the spiral shape of the outer outline of the cam 6, provides the tightening effect and eliminates any risk of vertical bouncing due to road bumps.
  • FIG. 12 shows the opening step, which is obtained by pushing on lever 15, so as to make it rock in a clockwise direction.
  • This provides a similar rocking movement of the sector 20' and of the axis 5' of the rocking bolt solidly mounted on the said axis, until it unhooks from the notch 12' of the head of the keeper 10' where its ramp reaches its horizontal position, while simultaneously, the unhooking of the hooking nose of the cam 6' is obtained by the counterclockwise rocking movement of the angular lever 26 to which it is secured, by the effect of the leg 28 of the lever 15' coming in contact with the corresponding abutment 25' of the aforementioned lever 26'.
  • the invention is not restricted to such material.
  • the invention is not restricted to the combination of means or process steps specifically mentioned, described or illustrated herein. It should be considered within the embodiment of this invention to operate such a lock by remote control or by means of a key.
  • the door lock described herein has been contemplated for car doors, it may be used for the trunk of a car or any other industrial use wherein the selfcocking of the lock would be advantageous.
  • a door lock comprising: BOLT MEANS HAVING SUB- STANTIALLY THE SHAPE OF A SEMICYLINDER AND CONSTITUTING A SEMICYLINDRICAL CATCH ADAPTED TO ROCK IN THE HOUSING,
  • a lock as recited in claim 1, wherein the keeper means comprises a plate having a broad head and a cross piece fixed on said plate, the said broad head being adapted to be laterally maintained within the said housing.
