Definitions

  • the present invention relates to a release apparatus for vehicle doors.
  • Rear (or lateral) doors usually arranged to close the loading compartment of trucks, vans, articulated trucks, heavy goods vehicles, trailers, and the like, are usually associated with particular apparatuses intended for their release, which can be operated when the user (for example the vehicle driver) wishes to gain access to the compartment.
  • engagement elements hooks, claws, etc.
  • the engagement elements in fact engage respective retention elements, which are fixed to the frame of the vehicle (above and/or below the door).
  • Each release apparatus of the known type therefore comprises a handle, which is integral with the rod and is arranged substantially outside the door, so that it can be gripped and turned by the operator who wishes to access the compartment.
  • the rotation of the handle causes the integral rotation of the rod and the consequent disengagement of the engagement elements from the retention elements, thus allowing the door to rotate freely.
  • the free rotation of the handle is first of all handed directly or indirectly by a button.
  • apparatuses of the known type are also provided with key-operated devices, which again allow free rotation of the handle only to the owner of the key, their use allowing indeed to deactivate a further hindrance to the movement of said handle (or of the button).
  • release apparatuses are required to ensure high resistance to stresses and impacts, first of all to prevent violent impacts against the door from deforming the handle until its functionalities are compromised, with consequent accidental opening of the door or in any case reducing the effectiveness of the solutions cited above.
  • the aim of the present invention is to solve the problems described above, by providing a release apparatus that ensures high resistance to stresses.
  • an object of the invention is to provide a release apparatus that ensures a high mechanical resistance to impacts, deformations and shocks of any type to which such apparatus or the door on which it is mounted might be subjected.
  • Another object of the invention is to provide a release apparatus that ensures strength and high reliability in operation while maintaining a low cost, safe application and a general structural simplicity.
  • Another object of the invention is to provide a release apparatus that ensures strength and high reliability in operation while allowing to reduce the weight and thickness, and therefore the cost, of the involved components with respect to known solutions.
  • Another object of the invention is to provide a release apparatus that can be obtained easily starting from commonly commercially available elements and materials.
  • Another object of the invention is to provide an apparatus that adopts a technical and structural architecture that is alternative to those of apparatuses of the known type.
  • a release apparatus for doors of vehicles which comprises a base, which can be anchored stably to the door, and a handle assembly, which can be fixed to at least one rod that can be coupled rotatably to the door and supports respective means for anchoring to the frame of the vehicle, said handle assembly being able to rotate with respect to said base between at least one locking configuration, in which the anchoring means can engage even indirectly the frame of the vehicle, and at least one release configuration, in which the anchoring means are in any case disengaged from the frame of the vehicle, in order to allow the free rotation of the door, said handle assembly comprising at least one main plate that has a substantially rectangular outline and defines, at a first edge, a stable insertion seat for the rod, a locking button being coupled rotatably to said base and being reversibly movable between at least one first angular position, in which it is arranged
  • the reference numeral 1 generally designates a release apparatus for doors of vehicles (typically but not exclusively for professional use).
  • These vehicles can be of the type of vans, heavy goods vehicles, trucks, articulated trucks, trailers, and like, and comprise therefore an internal compartment, which is closed by at least one door (usually arranged to the rear) and is intended to accommodate and transport goods of various types.
  • the apparatus 1 comprises a base 2, which can be anchored stably to the door: for example, the base 2 can be applied rigidly to the outer face of the door, or can be arranged and fixed in a recess that is provided for this purpose in the door proper.
  • the apparatus 1 comprises a handle assembly 3, which can be fixed to at least one rod A (shown only in Figure 1 for the sake of simplicity), which in turn, according to known manners, can be coupled rotatably to the door (and typically kept in a vertical orientation).
  • the rod A supports respective means (hooks, claws, etc.) for anchoring to the frame of the vehicle, substantially at one or both of its ends, which protrude from the space occupation of the door.
  • the handle assembly 3 can rotate with respect to the base 2 (about the axis B along which the rod A is arranged) between at least one locking configuration (in which it is shown in the accompanying figures) and at least one release configuration (in practice, the handle assembly 3 can oscillate about these configurations).
  • the rod A is rotated so that the anchoring means mentioned above can engage even indirectly the frame of the vehicle, preventing indeed the free rotation of the door (when of course the latter is already arranged so as to close the compartment).
  • this condition can be obtained, according to known methods, by arranging adequate retention elements on the frame of the vehicle, above and below the position assumed by the door, so as to be able to indeed affect the anchoring means and engage with them detachably.
  • the anchoring means are in any case disengaged from the frame of the vehicle, so as to allow the free rotation of the door and access to the internal compartment of the vehicle.
  • the handle assembly 3 comprises at least one main plate 4 that has a substantially rectangular contour and defines, at a first edge 4a, a stable insertion seat for the rod A.
  • the seat can be constituted for example by a through duct 5 that is indeed formed by the plate 4 (or is anchored thereto) at the first edge 4a.
  • a locking button 6 is coupled rotatably to the base 2 and in turn can move reversibly between at least one first angular position (in which it is shown in the accompanying figures) and at least one second angular position.
  • the button 6 is arranged so as to interfere with the movement of a second edge 4b of the plate 4, which lies opposite the first edge 4a. As long as it is retained in said first angular position, it is thus impossible to move the handle assembly 3 from the locking configuration.
  • the button 6 prevents any accidental releases caused for example by impacts and stresses against the door, the base 2 or the handle assembly 3, which might lead the latter to rotate in an unwanted manner (for example during vehicle motion) and therefore cause the disengagement of the rod A and of the anchoring means from the retention elements.
  • the button 6 is in any case spaced from the second edge 4b and therefore allows the free rotation of the handle assembly 3 (and the opening of the door).
  • the plate 4 has at least one lug 7 that extends transversely (and preferably at right angles) from the second edge 4b.
  • the button 6 is kept in interference with the rotation of a central portion 8a of the second edge 4b.
  • Two mutually opposite end portions 8b of the second edge 4b are therefore adjacent, on opposite sides, the central portion 8a and respective lugs 7 which protrude from them.
  • the plate 4 has at least one localized planar irregularity 9a, 9b that defines a further increase in the mechanical strength of said plate 4.
  • This irregularity 9a, 9b can in fact be obtained by plastic deformation (or also in another manner) and causes a localized strain hardening of the material (of the fibers involved), which indeed increases the mechanical strength of the entire plate 4.
  • the increased strength provided by the irregularities 9a, 9b and by the lugs 7 is such as to allow a general reduction of the thicknesses of material (for example metal plate) of which the plate 4 or the other involved components are made, so that indeed this does not penalize the general ability to withstand stresses, which is on the contrary assuredly increased, with respect to known solutions.
  • the irregularity 9a, 9b is constituted substantially by a localized hollow (a groove, a recess, a notch, or the like) provided along the face of the plate 4 that is opposite with respect to the base 2 (and to the door of the vehicle).
  • the irregularity 9a, 9b is constituted substantially by a localized ridge (an expansion, a raised portion, a protrusion) that protrudes outward from the face of the plate 4 that lies opposite the base 2.
  • both the hollow and the ridge (or other irregularity 9a, 9b), defined as mentioned on the face of the plate 4 that lies opposite the base 2, can correspond respectively to a ridge and a hollow on the other face, if the planar extension of the latter follows that of the former.
  • the second face (the one directed toward the base 2) can have a regular shape if indeed one wishes to provide the irregularity 9a, 9b only on the face that lies opposite to the base 2 (or optionally the reverse).
  • the apparatus 1 comprises two irregularities 9a (two hollows) which have an elongated shape along directions that are substantially perpendicular to the edges 4a, 4b and are arranged side by side at respective peripheral regions of the plate 4.
  • the apparatus 1 comprises two irregularities 9b (two hollows) that have elongated shapes that are aligned along a direction that is substantially parallel to the edges 4a, 4b.
  • the plate 4 has two lateral shoulders 10 that extend from respective sides substantially along the entire longitudinal extension of the plate 4, between the first edge 4a and the second edge 4b.
  • the handle assembly 3 comprises a handgrip 11, which is integral with the plate 4 on the opposite side with respect to the seat (the duct 5).
  • the handle assembly 3 is therefore provided in one piece or in any case the plate 4 and the handgrip 11 can move integrally.
  • the handgrip 11 can thus be gripped directly by a user in order to cause, after acting on the button 6, the rotation of the handle assembly 3 at least from the locking configuration to the release configuration.
  • the locking button 6 has an expanded head that defines an external surface 6a that is directed away from the base 2.
  • At least one portion of such external surface 6a is knurled, so as to facilitate interaction with the user, but in any case it is at the outer surface 6a that the user can apply a direct pressure to actuate the button 6.
  • the anchoring means engage directly or indirectly the frame of the vehicle and prevent the opening of the door.
  • the user In order to be able to access the compartment, the user must move the button 6 from the first angular position and at the same time move the handle assembly 3: the rotation of the latter in fact causes the rotation of the rod A and therefore the disengagement of the anchoring means. By applying further traction to the handle assembly 3 (for example on the handgrip 11) it is thus possible to move the door.
  • the apparatus 1 ensures high strength, first of all thanks to the choice to provide one or more lugs 7.
  • Such lugs are in fact arranged conveniently at the region that is most stressed (the end portions 8b) and prevent (or at least limit) dangerous deformations thereof when indeed the apparatus 1 is subjected to violent blows or impacts or to break-in attempts.
  • the ability to withstand stresses is further increased additionally by resorting to localized hollows or ridges (or other irregularities 9a, 9b), since these modifications in the plane shape of the plate 4 ensure an increase in mechanical strength.
  • the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.
