Definitions

  • the present invention refers to a device for operating the lock of a vehicle and in particular to a device for operating a rear lock of a sliding door of a van simply and economically by means of handles placed at the front part of the door.
  • An aim of the invention is to produce a device for operating the door lock of a vehicle, capable also of operating the lock from a significant distance by performing all four of the above functions, and which is at the same time very simple to construct and operate and can be manufactured at low cost.
  • the invention which relates to a device for operating the lock of a vehicle, comprising a first handle assembly mountable externally on a vehicle door, a second handle assembly mountable internally on the door, a key unit operable from outside the door, and a safety button operable from inside the door, characterized by the fact that it further comprises : an operating plate on which said handle assemblies, key unit and safety button act and which is attached by a first rod to said lock; means for rotatively supporting said plate comprising a first pin, integral with one of said handle assemblies and slidably engaged in a substantially rectilinear first aperture of the plate, and a linkage connected at one end to a point integral with one of the handle assemblies and at the opposite end to the said plate; and a second pin, integral with the first pin, which is engaged in a substantially L-shaped second aperture of the plate comprising a first substantially rectilinear branch positioned parallel to the first aperture and of length substantially identical to that of the latter, and a second branch positioned sub
  • a device for operating a known lock, not illustrated for simplicity, of a vehicle door 2 (also not illustrated for simplicity), in particular a sliding door of a van, of which only an upper front portion housing the device 1 is illustrated in figures 1 and 2.
  • It comprises essentially a known first handle assembly 3, mountable externally on the door 2, a second handle assembly 4, also known, mountable internally on the door 2, a known key unit 5, operable from outside the door and mounted integrally on the outside of door 2 in a known manner, not illustrated for simplicity, and a safety button 6 operable from inside the door, for example placed in correspondence with a window 7 thereof.
  • the device 1 further comprises an operating plate 10 bent appropriately, on which act simultaneously either handle assemblies 3,4 or key unit 5 and button 6 and which in turn acts in a known manner, not illustrated for simplicity, on the said lock not illustrated, for example by controlling the engagement of the lock directly by means of rod 11 so as to produce, when rod 11 is put under traction, the release of the said lock to be operated, thus causing the said lock to open.
  • an operating plate 10 bent appropriately, on which act simultaneously either handle assemblies 3,4 or key unit 5 and button 6 and which in turn acts in a known manner, not illustrated for simplicity, on the said lock not illustrated, for example by controlling the engagement of the lock directly by means of rod 11 so as to produce, when rod 11 is put under traction, the release of the said lock to be operated, thus causing the said lock to open.
  • Plate 10 is supported rotatively on door 2 by means of a cylindrical pin 12 engaged slidably in a substantially rectilinear aperature 13 through plate 10 and, in the example, obtained integrally as part of handle assembly 3, and by a spring 14, of the so-called "bistable" type, which is attached rotatively hinged, in parallel with the plane of plate 10, at one end to a point integral with the door 2, in the example to handle assembly 3 to which pin 12 is also integral and at the opposite end to plate 10, in the example engaged in a hole 15 of the same excentric device with respect to aperture 13.
  • the spring 14 is capable of operating as a linkage which can selectively trip plate 10 into two different positions, the first illustrated in figures 1,3,4 and the second in figure 5, in which pin 12 is positioned at the limit of travel in aperture 13 in correspondence respectively with a lower end 17 (in the first position) and an upper end 19 (in the second position) of the said aperture 13. Both ends 17,19 are rounded and shaped as a half-circle having the same diameter as pin 12.
  • device 1 further comprises a second pin 16 obtained integral to 12 in a lateral offset position with respect to it, for example always obtained as part of the handle assembly 3, pin 16 being engaged in a second aperture 21 through plate 10, obtained to one side and in an advanced position, through a lug portion 18 of the said plate 10.
  • Aperture 21 is substantially L-shaped, and comprises a substantially rectilinear first branch 23 positioned parallel to aperture 13 and having a length substantially identical to the latter, and a second branch 22 positioned substantially orthogonal to branch 23 and obtained in correspondence with an end 24 of the latter, disposed towards aperture 13.
  • Branch 22 of aperture 21 is curved and, in the example, has a curvilinear profile having the centre of curviture in correspondence with end 17 of aperture 13.
  • Device 1 finally comprises a compression spring 26 capable of preventing the abovementioned rotation of plate 10.
  • the spring 26, of the helical type is fitted directly on pin 12 and is connected integrally to it engaged at one end for example through a radial hole therein and, at the opposite end, is engaged slidably in a further rectilinear aperature 27 through plate 10 obtained parallel with aperture 13, on the part opposite to 21 and in a position less advanced than that of 13, and having the same length as aperture 13.
  • Plate 10 is further provided with respective contact lugs 28,30 positioned at right angles away from the plane of the said plate and capable of cooperating with respective known thrust levers 31 controlled in a known manner, against the action of respective compression springs 50, by respective known pivoted handles 32 of handle assemblies 3,4.
  • the position of pins 12,18 and the length of apertures 13,27 and of branch 23 of aperture 21 are designed in such a manner that in the first position that can be adopted by plate 10 (figures 1,3,4) the lugs 28,30 are positioned on a level with rods 31 (figure 3), whereby, following rotation of one or both of the handles 32 from the position illustrated by the continuous line to that illustrated by a dashed line (figure 2), the lugs 28,30 are intercepted (figure 4) by respective levers 31 receiving from them a thrust in the direction of the arrows capable of rotating plate 10 around pin 12 in the direction of the arrow (figure 4).
  • Rod 11 which controls the engagement of the lock to be operated is vice versa fixed to an L-shaped lever 43 obtained as part of plate 10 in a position diagonally opposite to aperture 13 with respect to bistable spring 14.
  • Lever 43 is further positioned parallel and excentric to apertures 21,13,27.
  • device 1 In use, device 1 normally operates with plate 10 in the position and angular configuration of figure 3.
  • Spring 14 holds plate 10 with pins 12 and 16 positioned at the limit of travel in apertures 13,21, in correspondence with ends 17,24. In this configuration, rod 11 is not stressed and the lock is therefore controlled in the closed position.
  • To open the door 2 it is sufficient to act on any of the handles 32. These rotate one of the levers 31 which intercepts one of the lugs 28,30, applying to plate 10 a moment with respect to pin 12.
  • plate 10 rotates around pin 12, against the action of spring 26 which goes into tension, to reach the angular position at the limit of travel shown in figure 4, which is stabilised by the abutment of pin 16 against the end of curved branch 22 of aperture 21 opposite to end 24 of branch 23 thereof.
  • rod 11 is put under tension in the direction of the arrow and controls the release of the lock, with consequent opening thereof.
  • the spring 26 resets plate 10 in the position of figure 4, whereby the lock can be locked again following closure of the door.
  • All four principal functions of the lock can be performed in correspondence with handles simply by means of a low cost plate that can be easily produced, mounted and replaced if it breaks.
  • the lock is then operated by the plate by means of a single rod or remote control, providing an operating device of maximum simplicity, limited weight and dimensions and low cost; the lock to be operated can finally be put in the rear part of the door, at a significant distance from the controls, which can be positioned vice versa in the front part.
