Definitions

  • the present invention concerns the technical field relative to the devices for the tow and assistance of motor vehicles in general.
  • the invention refers- to an innovative type of articulated arm for the towing of motor vehicles which results particularly versatile in use and, at the same time, compact when closed in a non-operative configuration.
  • Devices for towing motor vehicles which are commonly installed on emergency motor vehicles, for example the so-called civil service truck, have long been known. Such devices are realized through a base frame configured to be connected in a stable way to the frame of the emergency motor vehicle on which they are installed. Above such a frame there is a mobile mechanical arm provided at its end with simple hooks with which to engage the front or back part of the vehicle to be assisted so as to lift it partially and thus allow the towing of it.
  • such articulated mechanical arms are configured in such a way that, in non-operative rest position, they result closed, creating significant encumbrance.
  • the articulated mechanical arm closes, lowering itself below the frame of the emergency vehicle itself and arranging itself in such a way as to hide its bell tow.
  • bell tow is the back hook arranged in the back part of the frame of the emergency vehicle and that is used for the simple towing of other means of transport. Such vehicles are therefore born provided with such bells, normally homologated.
  • the emergency vehicle although it is provided with a back fixed hook, cannot make use of it except when the articulated arm is extended in an operative configuration and totally lifted above the load plane of the vehicle. It is clear that such a configuration of extended and lifted arm is particularly dangerous, especially in the case of transit in urban areas, since the length of such arms can exceed also the four metres.
  • the current articulated arms are not versatile and generally allow only a partial lift of the vehicle that is assisted, that is a lift of the front or back part of it.
  • the current articulated arms are not capable of realizing total lifts from the ground, neither in the case in which they assist particularly light vehicles.
  • the articulated arm (1) is realized in at least three portions (2, 3, 4) pivoted one to the other in succession, that is a first (2), a second (3) and a third portion (4).
  • appropriate actuating means (11, 12, 13), configured to realize the movement of ⁇ the arm between an extended position and a retracted rest position and vice versa, can be arranged in such a way as to move each single portion independently of the others.
  • the actuating means are arranged with respect to the said portions in such a way that the third portion (4) results rotatable close to the second, portion (3) and. the second portion (3) results rotatable close to the first portion (2) according to such rotation directions that, in retracted position, the. second portion (3) results bent between the first (2) and the third portion (4).
  • the arm when in use it is mounted on a fixed supporting surface 14 (for example the frame of the load plane of an emergency vehicle) , is capable of closing itself above such a surface, that is with the second and third portion comprised between the first portion 2 and the plane 14 itself.
  • a fixed supporting surface 14 for example the frame of the load plane of an emergency vehicle
  • the arm therefore results compact and does not come out from the load plane itself of the vehicle when in a rest configuration. Moreover, it is capable of clearing the bell tow of the vehicle itself completely, rendering it always usable, obviously except in the case in which the arm is extended to tow a vehicle to be assisted.
  • a device for the lift of a vehicle in general comprising:
  • the articulated arm comprises a first (2) , a second (3) and a third portion (4) reciprocally pivoted in succession one to the other, and in which, further, the said actuating means are arranged with respect to the said portions in such a way that the ' third portion.
  • (4) results rotatable close to the second portion (3) and the second portion (3) is rotatable close to the first portion (2) according to such rotation directions that, in retracted position the second portion (3) results bent between the first (2) and the third portion ( 4 ) .
  • the articulated arm (1) is hinged to such a fixed supporting surface (14) in such a way that, in the said retracted configuration, the, second and the third portion further result comprised between the first portion (2) and the said fixed supporting surface (14) .
  • an emergency vehicle for the lift and tow o.f motor vehicles in general, particularly tanks and characterized in that it comprises a fixed supporting surface - (14) and an articulated arm (1), as described, and that is connected to . the vehicle through the fixed surface (14) .
  • the second and the third portion result comprised, that is bent, between the first portion (2) and the said fixed supporting surface (14).
  • the vehicles to which to apply the said articulated arm can be of any nature and dimension. In such a manner, by appropriately dimensioning both the vehicle and the articulated arm itself, particularly heavy military means can also be recovered.
  • such an emergency vehicle can be a three-axle vehicle or a four-axle vehicle of bigger dimensions.
  • Last it is also described here a method for realizing the engaging and the subsequent lifting of a vehicle to operate the tow of it through an articulated arm (1), as described, and . comprising the operations of:
  • the said extraction operation comprising an anti-clpckwise lifting operation of the first portion (2) of the arm with respect to the fixed. surface (14) to which it is hinged, a subsequent anti-clockwise rotation of the second portion (3) that carries the said second portion in orthogonal position with respect to the first , portion (2), a subsequent clockwise . rotation that ' carries the third portion (4) in orthogonal position with respect to the second portion and a clockwise lowering rotation of the first portion, that carries rigidly the whole of the arm 1 close to the surface (14);
