Definitions

  • the invention concerns a device for opening and closing the rear doors of a van, particularly but not necessarily of the isothermal type, that is, of vans that transport goods at temperatures below freezing.
  • the vehicle that must load and unload goods from a ramp must stop at a certain distance, the driver must place chocks under the tires to keep the van stationary, then open the doors, remove the chocks and move the van closer to the loading/unloading ramp with the doors open.
  • shutters with automatic openings which open upwards have been designed.
  • these openings have the drawback that the doors take up a non-negligible internal space in the upper part of the van, that is, up to 200 millimetres, which does not allow pallets to be loaded above a certain height, with an evident loss in terms of material loaded on the van.
  • the present invention intends to overcome the problems highlighted above.
  • the aim is to ensure that the rear doors open automatically, even with remote control, with no need for the driver to get off the truck, thus allowing the driver himself to approach the ramp without having to get off the truck.
  • Another aim is to be able to load pallets up to the maximum height available inside the van.
  • Another aim is to minimize the time required to open and close the van doors during loading and unloading operations, in order to avoid any harmful heat dispersion.
  • the main object of the invention is to automate, as well as speed up, the opening and closing of the rear doors of an isothermal van as will be illustrated in detail in the following description.
  • figure 1 shows both the back of the isothermal van, indicated as a whole by 1, and the doors 2 and 3 that close the back of the van 1 itself.
  • the van 1 comprises a roof 1a, a bottom 1b, two opposite sides 4, and two doors 2 and 3.
  • a first door 2 has two hinges 21 and 22, while a second door 3 has the hinges 31 and 32.
  • the doors 2 and 3 are normally closed hermetically in order to prevent the cold contained inside the van from escaping.
  • Each door that is, both the first door 2 and the second door 3, is equipped with two actuators, one arranged in the median area with respect to the height and the other arranged in the upper end part of the van, as can be seen in figure 2 .
  • a first actuator 23 is arranged in a central position with respect to the height of the first door 2 and on the internal side thereof; said first actuator 23 moves a rod 25 over a small stroke through a cylinder 24 that can be either pneumatic or hydraulic or electric, in such a way that a small lever 26 exerts pressure on the edge of the first door 2 so as to open it by a few degrees.
  • the vertical cylinder 27 is provided with a pawl 29 at each end.
  • each pawl 29 releases itself from a corresponding housing 291 and allows the opening of the first door 2 by a few degrees.
  • This movement of a few degrees allows a second actuator 250, arranged above, on the roof of the van, to open the first door 2 in the following way.
  • the second actuator 250 is arranged on the inside of the corresponding first door 2 and is arranged at the level of either the roof 1a or the bottom 1b of said van 1.
  • the second actuator 250 is moved by a motor 252, which can be electric, pneumatic or hydraulic.
  • a rod 251 is operated by the motor 252.
  • Said rod 251 is integral with a rack 253, which in turn meshes with a pinion 254, so that this pinion 254 must necessarily rotate.
  • the pinion 254 is integral with a guide plate 255 configured to guide the translation of a movable bar 255c.
  • the movable bar 255c has two opposite terminal parts 255a, 255b, as can be easily seen in figure 5 .
  • a first terminal part 255a slides inside a slot 41 belonging to the upper internal part of a side 4 of the van 1.
  • the other, second, terminal part 255b of the guide plate 255 is connected to the vertical cylinder 27, wherein the vertical cylinder 27 is inserted in the vertical tubular element 28 arranged on the outside of the first door 2.
  • the guide plate 255 comprises a plurality of rolling bodies 260 configured to guide the translation of said movable bar 255c.
  • the movable bar 255c rotates with the pinion 254 and simultaneously translates in the radial direction R as prompted by the movement of the first door 2.
  • the resulting effect is that the guide plate 255 rotates in the direction opposite to the direction which caused the opening of the first door 2 and therefore the first door 2 closes again.
  • the latter also has a first actuator 33 in the central position, which moves by means of the cylinder 34 to obtain the release of the second door 3 so that it opens of a few degrees.
  • the second actuator 350 identical to the one 250 already described, opens the second door 3 working in the same way as the second actuator 250.
  • Figures from 9 to 12 represent the four configurations of the opening step of the pawls 29 and 39.
  • the right door moves first and is followed by the left door.
  • the left door must close first and be followed by the right door.
  • actuators 250 and 350 which in the construction example have been placed at the level of the roof of the van, perform the same function they would perform even if they were placed on the lower part, that is, at the level of the bed of the van.
  • the actuators 250 and 350 are at the top, in order not to hinder the movement of the pallets entering and exiting the van.
  • actuators 23 and 33 can be controlled remotely by means of remote controls of the known type and also with the aid of specific codes, in order to prevent the van from being opened and avoid any unauthorized or even fraudulent unloading of the goods.
  • the pawls 29 and 39 as well as the respective housings 291 and 391 are intended to be of a type known per se.
  • the present invention proposes a device for opening and closing the rear doors of a van, such that opening occurs automatically, even with remote control, with no need for the driver to get off the truck, thus allowing the driver himself to approach the ramp without having to get off the truck.
  • the invention proposes an opening and closing device which makes it possible to load pallets up to the maximum height available inside the van, thanks to the particularly flat and therefore compact structure of the device itself.
  • the invention proposes an opening and closing device that minimizes the time required to open and close the doors of the van during loading and unloading operations, in order to avoid any harmful heat dispersion.
  • the invention proposes an opening and closing device capable of automating, as well as speeding up, the opening and closing of the rear doors of an isothermal van.
  • the components and materials used may be any, depending on the needs and the state of the art.
