Definitions

  • the invention relates to a truck with a driver's roof.
  • the invention relates to an industrial truck with a driver's workplace and with at least one transparent pane for the protection of the driver.
  • the trucks include counterbalance forklifts and reach trucks, which have a driver's workplace and a mast arranged immediately in front of the driver's workplace with a lifting device which can be moved vertically on this, in particular a load fork.
  • These vehicles are used in particular in shelf storage with high rack heights. This creates the risk that the load or parts of the load fall down when handling, such as when settling or picking up from an upper shelf.
  • a driver's roof In order to protect the driver in the driver's workplace in such a case, it is known to provide a driver's roof.
  • This driver's shelter roof can be formed of a strut roof, which is protected by metal bars or grating above the driver's workplace of the driver.
  • a disadvantage of this prior art is a limited view of the driver on the upper working range of an industrial truck, i. the working area of the lifting device when it is moved on the lifting mast at the upper end of the lifting area.
  • a disadvantage of this prior art is that such discs provide without additional efforts for the necessary security from injury from falling loads, but especially when using glass it due to the smooth Surfaces to reflections comes. This can be particularly troublesome when the driver is disturbed by mirror images of instrumentation of the truck, such as reflections of the dashboard, or lying on the ground in the environment objects or the reflection of the floor itself, when he up through the driver's roof in wants to look at the work area of the fully or largely lifted lifting device. This effect occurs especially in the case of strong contrasts, such as when a dark hall ceiling occurs in combination with a light floor.
  • the angle of a driver's optical line of sight through the driver's canopy is always greater than 0 ° and may be up to 60 ° or more when the driver looks obliquely upwards in front of him at the working area of the lifted load-carrying means.
  • the angle of the optical axis depends on many parameters, including the geometry and mounting position of the disc in the driver's roof, the lifting height of the lifting device and any attachments, an inclination angle of the mast, the height of the driver, a seat adjustment of a possible driver's seat and the position of the truck in terms of its environment as well as the height of the object considered above the ground.
  • Bright objects in the area of the dashboard which are located in the extension of the mirrored optical visual axis of the driver, can then directly disturb the driver's view through a mirror image. Likewise, it may come through laterally mirrored floor surfaces and other objects that are mirrored near the passage of the optical line of sight through the driver's roof, disturbing the driver.
  • From the EP 0 949 188 B1 is a cabin known for a truck with a roof and a windscreen of bulletproof glass.
  • the present invention has for its object to provide a truck with a driver's workplace available, which avoids the aforementioned disadvantages and offers improved visibility for the driver.
  • the object is achieved in that in an industrial truck with a driver's workplace and with at least one transparent disc for the protection of the driver, the disc has an anti-reflection coating.
  • the disc can be part of a driver's cab.
  • Unwanted reflections can occur in all windows of a driver's cab, in particular also in the case of a windshield or side windows.
  • the disc is part of a driver's roof.
  • a driver's safety roof can have a transparent pane as an element held in a frame, but can also consist of such a pane even with a correspondingly strong design. This results in particularly great advantages, since it can not come to reflections of bright elements inside the truck itself, such as instruments in a dashboard. Furthermore, it can not come to reflections of a bright hall floor in the driver's roof, which are particularly disturbing compared to a dark hall ceiling as Background. Particularly advantageous is such anti-reflection of the driver's roof in its most frequent application in reach trucks or counterbalanced forklifts, which have high lifting heights and where the driver is dependent on the best possible view through the driver's roof on an upper working range of a guided on a mast lifting device in a raised state ,
  • the antireflection coating can be arranged on the driver facing the inside of the disc.
  • the disc can be provided on both sides with an antireflection coating.
  • reflections on the second, essential transition layer from a high refractive index of the disk to air on the outside are already reduced by the intensity attenuation when passing through the disk itself and are subject to further attenuation on the optical return path through further reflections.
  • An antireflection coating on the inside therefore shows great efficiency and is at the same time better protected against soiling and mechanical stress, in contrast to the outside.
  • the antireflection coating is optimized for a deviating from the vertical angle of incidence, especially in a slice of the driver's roof on the angle to a line of sight of an average driver in its working position to a maximum raised position of a load-carrying means on a mast.
  • a normal reflection value for a glass pane can be assumed to be 4% of the incident light intensity at normal incidence and be reduced to less than one percent by means of suitable anti-reflection measures which are customary today. It is too Consider that the transition at the bottom of the glass leads again and in addition to a reflection with a weakening of the intensity. However, at an angle of incidence of 60 ° with respect to the vertical, approximately 9% of the light is already reflected in the visible spectral range.
  • the optical line of sight of the driver with respect to the perpendicular to this disc at an angle that can be up to values of 60 ° at a position of a load-receiving device just above the driver's roof.
  • images of bright screens or luminous instruments in the area of a dashboard are then mirrored in the viewing axis or near the viewing axis in accordance with the laws of reflection of the same angle of incidence. Therefore, it is advantageous to optimize the anti-reflection to an incidence of light at an angle.
  • this is done by increasing the layer thickness and thus adapting the path of the light in order to achieve optimized extinguishing interference at a certain angle of incidence.
  • This angle can be optimized, for example, by determining a visual axis from a driver's normal working position, for example, a driver's seat position, and assuming an average person, such as the height of a 50 percentile man, as the measured and known average of a population. It can be selected as the end point of the visual axis a maximum raised position of a lifting device on a mast, but also a reasonable average height position above the driver's roof.
  • the antireflection coating may consist of a thin-film coating.
  • the antireflection coating may be formed by an etched transition layer.
  • the antireflection coating is formed from a nanostructure.
  • antireflection coating or as antireflection coating, including etched transition layers belong, nanostructures, "moth-eye-structures".
  • multiple coatings can also be used in order to optimize the antireflection coating over a broader range of visible light and it is possible to use coatings which have the effect of a gradual change in the refractive index.
  • the disc consists of a laminated glass pane, in particular a penetration-resistant laminated glass panes in a driver's shelter roof.
  • the figure shows schematically an industrial truck 1 in the form of a counterbalance forklift 2.
  • a lifting mast 4 is arranged with a load receiving means 5 in the form of a fork 6, which is guided vertically movable on the mast 4 and is shown here in a maximum raised position ,
  • the mast 4 can be tilted by tilting cylinders, not shown, by an angular range ⁇ , as indicated by the arrow.
  • a counterweight 8 is arranged.
  • a driver's cab 9 with a driver's safety roof 10 at the top, which has a pane 11 in the form of a laminated glass pane 12.
  • the laminated glass pane 12 protects against falling objects and is embodied, for example, as a so-called break-through-resistant laminated glass pane 12.
  • the laminated glass pane 12 is provided on the underside, which faces a driver, with an antireflection coating, which is optimized to an angle ⁇ as the angle of incidence for a medium spectral range of visible light.
  • the laminated glass pane 12 may also be provided on the upper side with an antireflection coating.
  • the angle ⁇ is thereby determined by a viewing axis 13 between a working position 14 of the eyes of a 50% average man on a driver's seat 15 in a position of the completely lifted load-receiving means 5.
  • the image 19 of bright instruments and, for example, a screen on a dashboard 16 is reflected in the viewing axis 13 in accordance with the laws of the mirror through the pane 11 as a mirror image.
  • the antireflection coating significantly reduces the intensity of such a mirror image, so that there is no impairment to the driver. Furthermore, the eye position of a 95% man 17 and a 5% man 18 are still drawn in. This makes it clear that the angle design of the anti-reflection coating protects most of the possible drivers from adverse reflections.
