Definitions

  • the present invention relates to an ice scraper, as is provided in particular for windshields and side and rear windows of vehicles, with a handle part and a blade.
  • ice scrapers have been known for a long time.
  • Many simple ice scrapers simply consist of a uniform plastic part with a handle and an integral blade part, on which a scraper blade is formed by appropriate shaping.
  • ice scrapers which are often made of polystyrene, are not very effective since the plastic material from which the scraper blade is made is often the same as the relatively soft plastic material (polystyrene or polyethylene) from which the handle is made and wears out very quickly.
  • Other ice scrapers are also already known in which a blade holder is provided for a scraping blade that can be used separately.
  • a plastic when using a plastic blade, a plastic is generally selected which is considerably harder than the plastic which is usually used for the handle of such an ice scraper.
  • Corresponding ice scrapers are also known, which have a metal blade, which mostly consists of brass. Although these brass blade ice scrapers are generally quite effective and useful, many consumers are afraid to use them because they fear the relatively hard metal may scratch the glass. However, this is not the case, since brass is much softer than glass and any scratches on windshields or other window panes of vehicles are usually generated by sand or other hard, abrasive material that may get between the blade of an ice scraper and the glass pane.
  • a metal blade especially if it is made of thin brass sheet, is sometimes a little too flexible or not powerful enough on its own.
  • ice scrapers are also known which, in addition to a scraper edge, also have a rubber scraper with which loose parts or water can be removed cleanly from a windshield or other glass pane.
  • the present invention is based on the object of creating an ice scraper with the features mentioned at the outset, which is more versatile than the previous ice scraper and which provides the suitable type of blade for each task.
  • an ice scraper with the features mentioned above, which is additionally characterized in that the blade is a two-layer double blade (3, 4), one layer (4) of which is made of plastic and the other of which is made of metal, the two scraping edges (7) of the double blade (3, 4) are arranged substantially parallel and at a close distance from each other.
  • the plastic layer is a hard plastic plate, e.g. B. is a polycarbonate plate
  • the metal layer z. B. is a sheet brass.
  • Brass sheet is on the one hand sufficiently stable, hard and at the same time also flexible, so that it can be used for a variety of scraping tasks, but at the same time it is also soft enough to prevent damage to the glass panes by the blade.
  • the hard plastic or polycarbonate blade can also be used in exchange for the brass blade, if it proves to be more suitable for a specific purpose, or if the brass blade is possibly worn out.
  • a soft plastic e.g. B. PVC or thermoplastic rubber instead of the hard plastic, because you have in the form of the metal blade in any case a relatively hard and stable scraping edge, while the other edge z. B. can take over the function of a wiper blade.
  • the two blade layers are expediently cast with one another, ie the plastic layer is molded or cast onto the metal layer.
  • an embodiment of the invention is particularly preferred in which the metal layer has cutouts through which plastic can flow during casting, which results in a positive connection between the two layers.
  • the layers can also be glued, form-fitting or
  • the plastic that has passed through the openings of the metal layer or of the metal sheet can expediently also be shaped into icebreaking tines.
  • the double blade is expediently designed as an indexable insert, which has a brass scraping edge and a polycarbonate scraping edge along its two opposite longitudinal edges.
  • the blades can be easily replaced and the entire ice scraper does not have to be thrown away.
  • the double blade has icebreaking tines on at least one side, and preferably on both sides, which have a protruding corner and can have, for example, a triangular cross section.
  • the ice scraper has a blade holder which essentially consists of a plate-shaped part which is provided with a longitudinal groove in its front narrow side, the width of the groove being the thickness of the double blade and the depth of the groove corresponds approximately to half the width of the double blade or can also be somewhat larger.
  • the edges or walls of the groove have cutouts for receiving icebreaker spikes, which are arranged on one side or on both sides approximately along the longitudinal center line of the double blade.
  • the icebreaker spikes could also sit on the edge of the groove, but the recesses that are preferably provided provide additional hold and better overall stability.
  • a particularly simple embodiment of the invention is formed in that the plastic blade and handle part are produced in one piece and the ice scraper is, as it were, molded onto the metal blade as a whole.
  • FIG. 1 shows a plan view of an ice scraper according to the invention
  • Figure 2 is a side view of the ice scraper shown in Figure 1, and a view from above of the blade side of this ice scraper, Figure 3 from top to bottom, first a view of the blade side, similar to the left part of Figure 2, including a view of the Ice scraper without an inserted blade, including only one blade to be used in a direction of view of the two scraping edges and at the bottom a side view of the double blade designed as an indexable insert, and FIG. 4 two cuts through a double blade in the area of icebreaker spikes, once with a cutting line perpendicular to the Course of a scraping edge and once parallel to one
  • FIG. 1 shows the ice scraper, designated overall by 10, which consists of a handle part 1 and a somewhat wider and flat blade holder 2.
  • a double blade is inserted into a groove at the front end of the flat blade holder 2 which can only be seen in FIG. 2, but only a half of the blade 3 can be seen from this.
  • a groove 9 is formed in the upper narrow side of the blade holder 2, the width of which corresponds precisely to the thickness of the double blade consisting of the blades 3 and 4.
  • the depth of the groove 9 is slightly more than half the width or height of the double blade 3.4.
  • the blade 3 is formed by a brass plate and the blade 4 is formed by a polycarbonate plate.
  • the scraping edge 7 of the brass plate and the scraping edge 7 'of the polycarbonate plate 4 run exactly parallel to one another, i.e. the two plates 3 and 4 are firmly connected to one another and are flush with one another along their upper edge. Instead of an exactly flush termination, the area between the scraping edges 7, 7 'could also be grooved. In any case, the scraping edges 7, 7 'remain at a close distance and parallel to each other.
  • icebreaker serrations 5 which protrude from the double blade 3, 4 on both sides and which are accommodated in suitable recesses which are provided along the upper edge of the blade holder 2 in the walls delimiting the receiving groove 9.
  • This can be clearly seen again in the top view from above in the left partial image of FIG. 2, where again the double blade consisting of the brass blade 3 and the polycarbonate blade 4 can be recognized, which are received in a groove in the upper edge surface of the blade holder 2.
  • the triangular profile of the icebreaking prongs 5, which are relatively sharp-edged, can be clearly seen here, so that their tip can effectively penetrate an ice layer.
  • the handle 1 has a front handle extension 1 'which encompasses the blade holder 2 on both sides. It goes without saying, however, that blade holder 2 and handle 1 can also be cast in one piece from a suitable plastic material and that they can also have a completely different shape.
  • FIG. 3 again shows different views of the blade holder 2 and the blade to be inserted into the blade holder 2.
  • the upper partial image in FIG. 3 essentially corresponds to the left partial image in FIG. 2, even if a larger number of icebreaking points 5 are indicated in the latter.
  • the second partial image from above in FIG. 3 shows the ice scraper without a blade inserted.
  • the groove width being matched to the thickness of the double blade 3, 4, so that the double blade is held in the groove 9 in a close fit becomes.
  • the icebreaker spikes extending to both sides can also be clearly seen in the view from above according to the third partial image from above in FIG. 3. At the very bottom in FIG.
  • the double blade 3, 4 is designed as a reversible plate, ie as an essentially rectangular plate, one side of which consists of a brass plate 3 and the other side of which consists of a polycarbonate plate 4. Approximately along the longitudinal center line of the brass plate 3, this has a series of equally spaced recesses through which the icebreaking prongs 5 receive an integral connection with the polycarbonate plate 4, which is arranged on the other side of the brass plate 3. Specifically, the brass plate 3 is inserted into an appropriate shape and the polycarbonate material from which the plate 4 and the icebreaking prongs 5 are made is molded onto the brass plate 3.
  • the plastic material penetrates the recesses in the brass plate and forms the icebreaker teeth 5 on the side of the brass plate 3.
  • the entire double blade 3, 4 is symmetrical, ie it can be turned through 180 °, so that after the wear of one of the edge pairs 7, the Scraper edges on the opposite side of the plates 3, 4 can be used.
  • the purpose of the icebreaker serrations 5 is also symmetrical, i.e. Due to their roof shape, they have two gable tips pointing in opposite directions, which serve to tear thicker layers of ice, which can then be scraped off with the brass edge 7 or the polycarbonate edge.
  • FIG. 4 shows two enlarged sections through the blades 3, 4 in the area of the icebreaker teeth 5 and the cutouts 8 in the brass plate 3.
  • the cutting plane runs along the ridge line of two opposing icebreaking tines 5, while in the lower part of Figure 4 the cutting plane is perpendicular to the ridge line of the roof-shaped icebreaking tines 5, i.e. runs essentially parallel to the cutting edges 7, T.
  • the dimensions of the recesses 8 are smaller than the icebreaker teeth 5 in their foot region. This means that the plastic material, which simultaneously forms the plate 4 and the icebreaking prongs 5, still easily grips around the edge of the cutouts 8, so that a tight and immovable connection between the brass plate 3 and the plastic plate 4 is produced in this way.
  • ice scraper With the ice scraper according to the invention it is possible to use either a metallic scraping edge or a plastic scraping edge for ice scraping, with one or the other scraping edge proving to be more suitable depending on the thickness and consistency of the ice layer.
