Definitions

  • the invention relates to an ice scraper device for removal of ice from a surface, especially from Motor vehicle window panes, according to the preamble of the claim 1.
  • Such ice scraper devices are state of the art known.
  • FIGS. 3a and 3b 10 A known ice scraper device is shown in FIGS. 3a and 3b 10 shown. It is essentially in three parts trained and includes a handle 12, one on the handle adjoining cavity 14 and a cavity 14 upstream acute-angled edge area 16. A heating coil 15 projects into this cavity 14 into it, which are located in the handle 12 batteries or batteries 13 is operated electrically.
  • the Cavity 14 has a large opening 17, which at Operation of the ice scraper in a first step over a surface covered with ice must be used to heat or thaw the ice. To the final removal of the ice from the surface subsequently a second step is required at which is the acute-angled edge region 16 is placed on the surface to do this beforehand scrape heated ice off the surface.
  • This object is the subject of the claim 1 solved. This provides for an ice scraper to arrange a heating element in the edge area, so that its edge during operation of the heating element is heated immediately.
  • Such an embodiment of the ice scraper device offers the advantage that for the effective removal of ice from only one work step is required for a surface is.
  • the ice is warmed up or thawed in the claimed device in the same step and at the same time as scraping off the ice.
  • the ice scraper device according to the invention can be used more effectively than known devices.
  • the device according to the invention is omitted the need for a constructive design Cavity with opening; rather, in the case of the invention Ice scraper the handle immediately to the Edge area are molded. To that extent is the invention Ice scraper device easier than known to produce comparable devices.
  • the heating element can be operated electrically.
  • the electrical Heating element is advantageously easy to use and causes the edge area to heat up quickly.
  • the heating element from an energy source associated with the ice scraper is supplied with electrical energy.
  • This can e.g. accumulators integrated in the handle of the ice scraper his.
  • Such an assignment of the energy source too the ice scraper has the advantage that the ice scraper anywhere, regardless of a permanently installed energy source can.
  • the heating element can also be from an external one Energy source are supplied with electrical energy.
  • An external energy source is e.g. the battery of a vehicle whose disks by means of the ice scraper to be freed from ice. The ice scraper can then either directly or through the cigarette lighter of the vehicle connected to its battery become.
  • the design of the Heating element as ohmic resistance.
  • the heating element can also be designed to be operated inductively his.
  • the heating element as a PTC thermistor, i.e. as a positive temperature coefficient PTC resistance element train because the heating element then when cooling, i.e. when the edge area with the ice in Contact comes because of the inherent thermostat effect automatically increases its power consumption and in this way tries the original temperature maintain.
  • the edge area can also independent of the actual sheathing of the PTC resistance element be trained. He can in this Case also made of a different material than the casing be made.
  • An independent design of casing and edge area offers the advantage of a simpler Maintenance possibility because with this configuration the resistance element in the edge area if necessary can be easily replaced.
  • the edge area be made of a heat conductive Form plastic or metal.
  • FIGS 1a and 1b show the ice scraper device according to the invention to remove ice from a surface, especially of motor vehicle window panes.
  • the Ice scraper device includes a handle 12 and directly thereon then an edge area 16, which a flat underside 22 and preferably an acute angle trained edge 18. To operate the ice scraper edge 18 will surface put on and with their help the ice is removed from the surface scraped.
  • the edge region 16 has a heating element 20, which in particular the edge 18 during operation of the ice scraper heated. Due to the heated edge 18 Process of scraping the ice off the surface facilitated.
  • the heating element 20 is preferably operated electrically.
  • There are electrical cables in the ice scraper for this purpose 21 relocates the heating element 20 to an energy source connect.
  • an energy source are suitable for Example batteries and accumulators 13, which preferably integrated in the handle 12 of the ice scraper are.
  • Such an embodiment of the ice scraper device offers the advantage that it is spatially mobile; the Area of application or action radius of the ice scraper is not by the length of an electrical cable (here not shown), which the heating element 20 with an external Energy source (not shown here), connects, limited.
  • the ice scraper device is advantageously a charger assigned which is a charge of the batteries 13 enables the battery of a motor vehicle.
  • the charger can then either directly or via the Cigarette lighter of the motor vehicle connected to the battery become.
  • FIG. 1c shows an alternative embodiment of the underside 22 of the edge region 16 of the invention Eiskratzvorraum. Accordingly, the bottom 22 spans one cavity 24 protruding into edge region 16 on which is bounded by a peripheral edge. Reference numerals 18 and 18 'in FIG. 1c preferably denote straight sections of the circumferential edge. When the heating element 20 is operating in the edge region 16 this heats the entire bottom 22 including the peripheral edge as part of the underside. Preferably is the bottom including the surrounding Edge made of thermally conductive material.
  • a vacuum By the Vacuum creates a force that the ice scraper device pushes or sucks to the surface while the Ice scraper device is guided over the surface.
  • This force effect created by the vacuum contributes to ensure that in particular the edge sections 18 and 18 'at all times during a scraping process rest on the surface, creating an improved scraping effect is achieved.
  • Heating element 20 an elevated temperature in the Cavity 24 a desired thawing of ice residues, which in a first scraping process through the first edge section 18 were not scraped off. Because of their thawed This ice residue can then be in one state second subsequent, caused by the edge section 18 ', Scraping process from the surface.
  • FIG 2 shows a second embodiment of the invention Ice scraper, which in difference to the device shown in Figure 1 three edge areas 16-1, 16-2 and 16-3.
  • the edge areas can themselves in their length and the size of their acute angles Distinguish ⁇ 1, ⁇ 2, ⁇ 3 from each other.
