Definitions

  • the present invention relates to disengageable doorstop for vehicles.
  • the invention relates to device as described in the preamble of claim 1, which is known from FR-A- 2721649.
  • This document describes a doorstop that allows a normal door-open position with an opening angle of approximately 90° and an extra-wide position.
  • the known device consists of a first and a second support connected together via a tie rod that is hinged to the first support and can slide between a pair of rollers carried by the second support.
  • One end of the tie rod is shaped like a hook with a V-shaped profile that engages with one of the rollers when the door is in the normal open position.
  • the known device is equipped with a disengagement mechanism including a handle that must be manually operated to disengage the tie rod from the rollers to open the door beyond the normal open position.
  • the object of the present invention is to provide a doorstop of the above-specified type that is simpler and more economical than the previously cited known device and which also allows a simplified door-opening manoeuvre to the extra-wide open position.
  • this objective is achieved by a doorstop with the characteristics specified in Claim 1.
  • 10 schematically indicates a vehicle with a pair of rear doors 12 hinged to the vehicle's chassis along their respective vertical axes.
  • the doors are predisposed for stopping in a closed position, a normal open position of approximately 90° and an extra-wide open position, indicated in figure 1 with a continuous line.
  • a doorstop according to the invention is indicated as 14.
  • the device 14 includes a first support 16, destined to be fixed to a pillar 18 forming part of the vehicle chassis 10.
  • the pillar carries, in a known manner, the hinges for each door 12, the hinge axes of which are schematically indicated as 20.
  • the doorstop 14 includes a tie rod 22 with one end 24 attached to the first support and turning around an axis parallel to the hinge axis 20 of the door 12.
  • the tie rod 22 is composed of a metal rod with two opposed rolling surfaces 28 on which the engagement seats 30 and 32 are formed.
  • the other end 34 of the tie rod 22 has a rounded form in the plane at right angles to the rotational axis 26 of the tie rod 22.
  • the rounded profile of the other end 34 smoothly merges with the lateral rolling surfaces 28 and, in particular, with the engagement seats 32 formed on the rolling surfaces 28 close to the rounded end 34.
  • the rounded profile of the end 34 does not have undercut portions or a form that could cause engagement of the end part 34.
  • the doorstop 14 also includes a second support 36, destined to be fixed to the door 12.
  • the second support 36 carries a first roller 38 and a second roller 40 that cooperate with the lateral rolling surfaces 28 of the tie rod 22.
  • the first roller 38 is mounted on support 36 and free to rotate around a fixed axis.
  • the second roller 40 is mounted to freely rotate around a mobile axis, which is elastically pushed against the first roller 38.
  • the mobile roller 40 is mounted, free to rotate, on the end of an elastic element 42, composed of a shaped metal rod, one end 44 of which constitutes the mobile axis of rotation for the second roller 40.
  • the elastic element 42 imparts a predetermined elastic force on the second roller 40 that tends to push it against the first roller 38.
  • the two rollers 38 and 40 are only subjected to the action of the elastic element 42 and can thus be separated from each other by overcoming the elastic force that tends to keep them together.
  • the tie rod 22 is articulated on the first support 16, turning around the said axis 26 via a pivot pin 46 and a bush 48.
  • the pivot pin 46 has two projecting parts on which two parts of a return spring 50 are inserted.
  • the return spring 50 applies an elastic force to the tie rod that tends to make it turn in the direction indicated by arrow 52 in figure 5.
  • the tie rod 22 has a plastic covering 54, preferably applied via co-moulding.
  • the covering 54 extends onto the part of the tie rod shown with hatched lines in figures 2, 3 and 4.
  • Figure 2 illustrates the configuration of the doorstop corresponding to the door-closed position.
  • the force exerted by the elastic element 42 pushes the rollers 38 and 40 against the lateral rolling surfaces 28 of the tie rod 22.
  • the motion of the door opening causes a rotation of the door 12 and the second support 36 that is fixed to it around the hinge axis 20. Due to this rotation, the rollers 38 and 40 roll along the lateral sides 28 of the tie rod 22.
  • the device 14 holds the door in a partially open position and when the rollers 38 reach the other engagement seats 32, the door 12 will be in the normal open position, corresponding to an opening angle of approximately 90° (figure 3).
  • the position shown in figure 3 is a stable stop position because a predetermined torque must be applied to the door to move it from this position.
  • the return spring that acts on the tie rod 22 tends to push it in the direction indicated by arrow 52 until the tie rod makes contact with the end stop.
  • This end stop could, for example, consist of a vehicle surface, such as a surface of the rear lights unit mounted on the pillar 18.
  • the plastic covering 54 on the surface of the tie rod 22 serves to avoid damaging vehicle surfaces when the tie rod rests against them.
  • the return spring 50 (figures 5 and 6) keeps the tie rod 22 in a predetermined reference position when the latter is disengaged from the second support 36.
  • the rollers 38 and 40 come into contact with the rounded end of the tie rod 22 when the door has an opening angle slightly greater than the normal open position.
  • the user perceives an increase in resistance and, to engage the tie rod 22 with the rollers 38 and 40, it is sufficient to continue pushing the door 12 in the direction of closure.
  • the rounded end 34 separates the rollers 38, 40 and the tie rod 22 spontaneously slides between the rollers.
  • a doorstop according to the invention is also particularly simple and economic due to the fact that no disengagement mechanism is required.
