Definitions

  • the present invention relates to an improved window lift mechanism, and in particular to a window clamp for a window lift mechanism for use in a motor vehicle.
  • Such window lift mechanisms typically comprise first and second guide rails upon which a window pane to be moved is guided.
  • the window pane is guided by clamps associated with the guide rails which are adapted to slide along the guide rails. In this way, the window pane may be raised or lowered as required by a user of the motor vehicle.
  • the guiding of the clamps may conveniently be achieved by running a cable along the guide rails, connecting the cable to the clamps and driving the cable while keeping the clamps free of the guide rails.
  • each window clamp may be urged to rotate along a radius defined between the centre of gravity of the window clamp and the cable to which the clamp is secured. This causes the window to bump into other parts of the door assembly resulting in an unwanted rattling noise when the door is closed in this way.
  • This problem is worse for frameless windows, since it is not possible to provide any support for the window in a frame.
  • a choice has been required between added weight or an undesirable noise.
  • a window lift mechanism comprises a first guide means and a second guide means, a carrier cable means carried by the first and second guide means, at least one window clamp associateed with one of the guide means, the at least one window clamp being spaced from the associated guide means and secured to the carrier cable means to support a window pane, characterised in that a centre of gravity of the at least one window clamp when loaded with the window pane lies in a plane defined by the associated guide means and the carrier cable means.
  • the window lift mechanism 4 comprises a frame having first and second guide rails 6,8 secured to a door panel 10, a cable 12 fed along a circuit including the first and second guide rails, means to drive the cable around the circuit, and first and second window clamps 16,18 secured to the cable and associated respectively with the first and second guide rails.
  • a window pane 20 is supported at a lower edge 22 by the first and second window clamps.
  • the cable is typically a cable of the Bowden kind, and may be driven by a motor 14. In the illustrated embodiment, the motor is mounted to the first guide rail 6.
  • the window clamps are secured to the cable by way of integral connecting means 26,28 such that the window clamps are disposed to one side of the guide rail and the cable.
  • the window pane together with its associated window clamps, is shown in a fully lowered position 30 and in a fully raised position 32. It will be appreciated that when the window pane 20 is in the fully raised position the window pane is held in position both by the window clamps at the lower edge but also at an upper edge 24 of the window pane by an upper edge of the door panel 10. When the window pane is lowered, the window pane is no longer held by the upper edge of the door panel and so obtains a measure of freedom of movement.
  • the door panel When the door is moved into a closed state from an open state, the door panel will be halted by a door frame of the vehicle.
  • the window When supporting the window pane, the window clamps have a centre of gravity through the window clamps.
  • the centre of gravity is offset from the cable by the connecting means, and so the momentum of the window pane acting through the centre of gravity leads to a tendency for each of the window clamps to swing about the cable. It will be understood that the cable also has some resilience, and so does not act to prevent this occurring.
  • the twisting of the window clamps about the cable also places undesirable stresses and strains upon the window pane.
  • FIG. 2 to 4 a portion of a window lift mechanism according to the present invention is shown.
  • a lower edge 40 of a window pane 42 is shown supported in a window clamp 44.
  • the window pane may be constructed of glass, plastics or any other suitable material.
  • a guide rail 46 is shown located to the rear of a guide cable 48.
  • the guide cable extends along the guide rail.
  • the guide cable may conveniently be driven by a motor (not shown).
  • the gripping portion is generally "U" shaped in side section and is provided with a flange 62,64 along first and second arms 66,68 of the gripping portion.
  • the flanges serve to overlap the upper edge of each member to locate the gripping portion 50 in position with respect to the first and second members.
  • the gripping portion is conveniently as deep as the recesses 56,58 provided in each member.
  • An inner surface of the gripping portion may be provided with ridges 70 to aid in gripping the window pane.
  • the gripping portion is not essential but serves to prevent unwanted damage to the window pane that may occur if the window pane is gripped directly by the first and second members.
