Definitions

  • the present invention relates to a device for controlling the opening and closing of a motor vehicle door or hatchback door, particularly rear doors of commercial vehicles.
  • the back door or hatchback door of commercial vehicles is fitted with a tie rod that does not allow the door to open wider than 90°, and at the same time acts as a stopping means to prevent the door from closing unadvertedly.
  • the said unhooking operation is not free of inconveniences, as it is necessary to use both hands, one for pushing the door open and the other for unhooking the tie rod.
  • tie rod is often covered with grease to facilitate it in sliding, which requires the use a suitable protection to avoid being dirtied, such as a glove or a rag.
  • this object is accomplished by the provision of a device for controlling the opening and closing of a door or hatchback door, particularly for rear doors of commercial vehicles, as claimed in claim 1.
  • numeral 1 designates a part of the body of a motor vehicle, in particular a commercial vehicle, to which a tie rod 5 made of C-shaped contoured sheet metal is attached by means of a bracket 3.
  • Tie rod 5 is hinged to bracket 3 by means of a pin 7 and is urged by a spring 9 against an abutment 11 formed in the bracket, so as to reach a predetermined angle with respect to the bracket, as will be more apparent hereinafter.
  • the end portion 12 of tie rod 5 is shaped as a hook 13. On the outer upper face of end portion 12 the tie rod bears a first roller 15 rotatably mounted on a riveted pin 17. Fitted within the space formed by the C-shaped end portion 12 and also rotatably mounted on pin 17 is a second roller 19, of larger diameter with respect to the first roller 15. The lower outer face of said end portion 12 bears a support member 21 fixed by riveted pins 17 and 20. Support member 21 forms a semi-circular contoured seat 23.
  • a flat support 27 is fixed to the door frame 25 facing the bracket 3.
  • Flat support 27 is provided with upper and lower tongues 29, 30 orientated at a 90° angle and forming therebetween a guiding passage for the end portion 12 of the tie rod 5.
  • a torsion spring 33 is fixed to the front side of flat support 27 facing the bracket 3.
  • the lower end portion 35 of torsion spring 33 supports a third roller 37 rotatably mounted by means of an elastic ring 39.
  • Torsion spring 33 is kept in position by a folded part 40 of flat support 27.
  • a lever 41 composed of a first and second blades 42, 43 forming and open V facing the base of flat support 27 is mounted for oscillation within the upper tongue 30 by means of a pin 44 fixed to the apex of said V and a C-spring 45 at a distance such to allow the passage of the first roller 15 between the same lever and the base of flat support 27.
  • Said tongue 30 further provides a guiding portion 47 folded at a 90° angle with respect to said upper tongue and oriented such that its extension encounters a the flat part of flat support 27 at an acute angle.
  • a traction spring 49 is connected to the lever 41 and the guiding portion 47 in order to keep the blade 43 with its end portion pressed against said guiding portion 47, whilst the end portion of blade 42 is pressed against the base of flat support 27.
  • the tie rod of the door can be unhooked automatically by means of a simple and reliable device, without the need of intervening manually on the tie rod.
