Definitions

  • ABSTRACT Apparatus for starting the engine of an automotive vehicle and only permitting the reengagement of the starter after interrupting the ignition and/or the feed of an injection pump associated with a switch provided with at least three successive positions inclusive of stop, ignition on and start positions, and opposing a second movement towards start position without first going towards the stop position.
  • the apparatus comprises a turnable plate having an axis of rotation and adapted for controlling the operation of the switch of the starter circuit, the turnable plate having a circumferential groove therein extending substantially concentrically with respect to its axis.
  • a stator faces the plate and has a blind bore therein in which a guide member is supported for free slidable and rotatable movement.
  • An eccentric pin is secured to the guide member and extends therefrom into the groove.
  • the groove has a widened terminal zone with three levels thereat, and the pin is engaged in the groove at the highest level in the stop position which is remote from the terminal zone.
  • the pin travels at the highest level from one end of the groove to the other as the plate is rotated and passes successively from the stop position, to the ignition position and then to the start position. The plate then rotates in opposite direction whereupon the pin descends to the lowest level at a running position where the ignition remains on.
  • a shoulder is provided between the lowest and middle levels to prevent return rotation of the plate from the lowest level to the middle level and hence direct return to the stait position.
  • the plate is turnable further in this opposite direction towards the stop position whereupon the ignition is cut and the pin rides onto the highest level of the groove so that the plate can new be returned to the start position.
  • the present invention relates to apparatus for starting the engine of a vehicle and only permitting the reengagement of the starter after cutting the ignition or the feed of the injection pump.
  • a recall spring returns the switch element from the starting position to the running position whereat the ignition remains on. If the engine does. not start readily, the conductor has the tendency to return the, switch to the starting positionwhich can produce undesirable interference between the teeth of the drive gear of the engine and the pinion of the starter.
  • An object of the invention is to provide simplified apparatus which avoids the above-noted disadvantages while permitting it to operate with all types of switches (with or without a mechanical anti-theft device
  • This apparatus can be connected at any point in themechanical transmission of a manipulation key or button, either with the electrical switch or with the mechanical anti-theft device without modifying the internal structure of these particular devices.
  • the apparatus comprises in the mechanical transmission of the starter button, a turnable plate provided with a groove therein in the form of a sector forming a cam groove for receiving an eccentric pin fixed to a push guide received in a stator, said push guide being axially rotatable and/or freely slidable in the stator and accommodating itself to the groove in the plate and the direction of displacement of the plate to meet an abutment, or a ramp to require the switch to return from the running position to the stop position before attempting a new starting manipulation.
  • This apparatus has no effect whatsoever on the other apparatus activated by the rotor, particularly the automatic return to the running position from the start position as soon as the ignition key or the switch button is released.
  • the invention therefore contemplates two essential elements; namely the plate and the pin of the push guide, and the elastic means acting on the pin to press the same into the cam groove formed in the plate.
  • FIG. 1 is a diametral cross-section of the apparatus according to the invention in the stop position, and for purposes of clarity the switch and/or the anti-theft blocking mechanism to which it is attached are not shown;
  • FIG. 2 is a front view of the apparatus of FIG. 1,
  • FIG. 3 is a sectional view taken on line III-III in FIG. 2
  • FIG. 4 is a sectional view taken on line IVIV in DETAILED DESCRIPTION
  • a stator 1 having a longitudinal blind bore 2 which is eccentrically located in the stator.
  • a push guide 3 is freely supported in bore 2 for slidable and rotatable movement therein.
  • the push guide has a fixed, eccentric pin 4 at its exterior face.
  • a spring 5 is mounted in the bore 2 and acts on the push guide 3 to urge the same outwardly from the bore.
  • a turnable plate 6 is coaxially disposed with respect to the stator l and has a groove 8 in the surface facing the stator.
  • the groove 8 extends circumferentially in the plate 6 and is formed as a semi-circular sector serving as a guideway for the pin 4 in the fashion of a cam groove.
  • the groove 8 has a variable profile as evident from the sectional views in FIGS. 3 and 4.
  • the groove 8 is formed, at the beginning of its profile, as a concentric circle at a radius to receive the pin 4.
  • the groove Sis not of the same depth and width over its entire length.
  • the bottom of groove 8 corresponds to the stop position as illustrated in FIGS. 1 and 2 and permits abutment over its entire depth of pin 4 along portion 8a extending substantially over one quadrant i.e. an arc of
  • the portion 8a is of constant depth and width and at section line III in FIG. 2, the profile of the bottom of the groove forms two transverse concentric zones, the outermost of which extends about 90, while the inner descends via a ramp to a maximum depth at 8c which is bounded by a rounded shoulder a.
  • a portion 8b extends in continuation of 8c and has a depth intermediate the maximum depth at 8c and the depth of 8a.
  • the pin 4 engages portion 8a of groove 8.
  • the pin 4 situates itself ahead of the axis of the push guide 3 while remaining externally disposed.
  • the friction resulting from the pressure of the push guide 3 on its guideway tends to return to pin 4 towards the rear by pivoting around the axis of the push guide 3.
  • the pin 4 is therefore thrust towards the lateral external wall 9 of the groove 8 which forms a stop and whose radius is less than the radius corresponding to the maximum eccentric position of the pin 4. It follows that after each rotation in one direction of the other of the plate 6, the pin 4 engages and slides in the portion 8a of the groove 8.
  • the pin 4 reaches the ignition on or energization position (immediately before the angular position in FIG. 8) and continues to the extreme position in FIGS. 5 and 6, which corresponds to the starting position. At this moment, the extremity of pin 4 is engaged at the intermediate depth 8b.
  • an elastic means acts on plate 6 to bring the plate 6 in reverse direction of rotation i.e. counter clockwise, to the running position (in which ignition remains on or the feed of the injection pump continues).
  • the pin 4 lodged in portion 8b comes into contact with lateral ramp 10 which orients it and engages it in the deepest portion 8c at the time when the running position is reached. This is shown in FIGS. 7 and 8.
  • Apparatus as claimed in claim 1 comprising elastic means acting on said guide member to urge the pin outwardly from said blind bore.
