Definitions

  • This invention refers to a hinge for a motor vehicle door or hatchback door, in particular for rear doors of commercial vehicles.
  • the door can also be required to stop in more than one position in order to facilitate the loading and unloading of goods.
  • the hinges which are commonly in use at present do not allow the door to open wider than 180°, since its rotation is hindered by the motor vehicle side to which it is attached.
  • the aim of this invention is to overcome the above mentioned drawbacks.
  • the subject of which is a hinge for a motor vehicle door or hatchback door capable of letting the door complete a rotation angle of more than 180 degrees, comprising two fastening elements attached respectively to the vehicle bodywork and the motor vehicle door, these elements being movably connected by a first connecting rod by means of two first rotation pins which are parallel and positioned at the ends of the connecting rod; a second connecting rod, facing the first one and being connected at its ends to said two fastening elements by means of two second rotation pins positioned parallel to said first pins, characterized in that the first connecting rod has, on its surface facing the second connecting rod, a control and stop device for the door movement and in that the second connecting rod has, on its surface connecting the first connecting rod, a small pin which is capable of working with said control and stop device during use in order to make it rotate.
  • (1) indicates the bodywork of a motor vehicle and, particularly, the rear end of a commercial vehicle, while (2) indicates the door frame.
  • the first fastening element (3) and the second fastening element (4) are connected, by means of screws (5) to the bodywork (1) and the door (2), respectively.
  • the two fastening elements are rotatably connected together by a first connecting rod (6) at points (7) and (9) on the first and second element, respectively.
  • the connection is obtained by means of two pins (10) and (11) having parallel axes.
  • the connecting rod has a U-shaped profile with its ends facing the vehicle, almost forming a closed inner compartment.
  • first connecting rod (6) Facing the first connecting rod (6) is a second connecting rod (12) which is connected to the fastening elements at points (14) and (15) by means of pins (16) and (17).
  • Said second connecting rod is substantially contained inside the first connecting rod (6), while the axes of the two connecting pins (16) and (17) lie on the same plane comprising the axis of the pin (10) which connects the first connecting rod to the first element.
  • the second connecting rod (12) supports a small pin (19) which can engage, during use, with a seat (20) machined in the upper and lower rollers (21) and (22) of a control and stop device (23) which is fixed to the inner side of the connecting rod (6) by means of a pin (24).
  • the end of the second connecting rod could also be connected to the second fastening element by means of an adjustable attachment.
  • the one in the figure comprises a tie rod (25) with an eyelet head (26) and a corresponding centering bushing (27).
  • the control and stop device (23), besides rollers (21) and (22), which are hinged so as to rotate freely on the pin (24), and which rollers have, furthermore, limit (rotation) stops (29) and (30) and a toothing (31) on their inner surface, comprises two bushings (32) and (33) which are coaxial to and axially slidable on the pin, said bushings having a toothing (35) on the surface facing the toothing (31).
  • the bushings (32,33) are biased against the corresponding rollers (21,22) by a spring (36), which is interposed coaxially to the pin (24) and which is adjustable by means of a threaded ring nut (37), in such a way that the toothings can engage.
  • ridges (40) and (41) are machined in order to engage with the corresponding limit stops (29) and (30) obtained on the rollers (21,22), while a projection (42) again obtained on the surface of the connecting rod (6) works in conjunction with seats (not shown) obtained on the bushings (32) and (33) in order to prevent the rotation around the pin (24).
  • the hinge according to the invention works in the way described below.
  • the rotation given to the rollers makes the toothings 31 and 35 engage when the door reaches the end of its travel, thus stopping the door without using separate elements fixed to the bodywork.
  • the connecting rod 12 of the first embodiment is formed into two parts, a substantially straight main connecting rod 50 and a secondary curved connecting rod 52.
  • Connecting rods 50, 52 are interconnected therebetween at respective ends 53, 54 by means of a pin 55 enabling the two connecting rods to rotate with respect to each other.
  • the opposite ends of connecting rods 50, 52 are still rotatably connected by means of a pin, as in the first embodiment, to fastening elements 3 and 4, respectively.
  • the pin 55 on which the ends 53 and 54 of connecting rods 50 and 52 are pivoted, is force fitted on rollers 21, 22 forming the control and stop device 23.
