Description

An ice scraper

Field of the Invention

The present invention relates to a de-icing tool for use on glass, in particular to an ice scraper for use on vehicle windows.

Background

Ice scrapers for de-icing glass, for example vehicle windows are known, and have for example a hard plastic blade for removing hard ice, a hard rubber blade for removing softer ice such as hoar-frost, or both provided on opposite sides of the scraper for use one at a time. It is known to use such tools with a de-icing spray for example provided in an aerosol or pump-misting action container. Use of the scraper and the spray is inconvenient however, relies on the availability of both in or at the car, and in the case of a pump-action spray bottle, liable to messy drips and leakages. It is also inefficient, as the spray is often used over a wide area while the scraping action is slower, so leading to waste of the cleaning spray and in the case of alcohol-based cleaners, evaporation. Also, in use of separate spray de-icers, the spray can leave streaks on the window, needing a further wiping action to remove it. A rubber wiping blade can be used for this, but requires a further pass over the window before the cleaner dries in place -which needs quick action, especially in cold dry conditions. A device to make spray de-icing and clearing of ice from vehicle windows easier would have practical and commercial utility.

Summary of the Invention

According to the present invention there is provided an ice scraper comprising: a body having a proximal end providing a handle and a distal end providing a scraping edge; a rubber blade mounted on the underside of the body and arranged in use to contact a surface behind the scraping edge when the scraping edge is held in contact with the surface; a spray means mounted on the body and arranged in use to spray in front of the scraping edge, in which the spray means comprises a nozzle mounted on the body, a spray button arranged in use to control flow of spray liquid, a spray liquid supply container mounted on the body, a fluid pathway linking the spray liquid supply to the spray button and the nozzle, and fluid actuation means arranged in use to urge liquid from the spray liquid supply container to the nozzle.

In use, the spray means is controlled by the spray button to spray de-icing liquid from the spray liquid supply ahead of the scraping edge on the front of the scraper. This melts or loosens the ice. The scraping edge is then moved forward to scrape the ice away. The rubber blade follows the scraping edge and wipes the surface of the window, so clearing any residual water, particles of ice or spray liquid and leaving a clean window without streaks.

Preferably the fluid actuation means comprises pressure and the spray liquid supply comprises a pressurised container. In a preferred embodiment the container is an aerosol container comprising a compressed propellant gas and spray cleaning liquid.

Preferably the spray control button acts to open or close the fluid pathway.

In a further preferred embodiment the spray means comprises pump means usable to cause liquid to flow from the spray liquid container along the fluid pathway. In a preferred embodiment the spray button acts to operate the pump means. In a further preferred embodiment the pump means is a compression pump means adapted to pressurise a fluid within the container, for example a volume of air in the container.

In one embodiment the pump has a pump actuation handle usable to pressurise the container and the spray button acts to open the fluid pathway. In a further embodiment the spray means comprises a liquid pump means that pumps liquid from the liquid supply along the fluid pathway. Preferably the spray button actuates the liquid pump means.

Preferably the liquid supply container is adapted to be detachable from the body and from the fluid pathway, the spray means comprising fluid connection means to connect the fluid pathway to the container. In a preferred embodiment the liquid supply container is adapted to be a single use disposable. In an alternative embodiment the liquid supply container is adapted to be re-filled and used repeatedly. In a further embodiment the supply container is mounted permanently on or forms part of the body and comprises a liquid closure adapted to allow filling of the container.

The scraper may have one nozzle or multiple nozzles, for example in a preferred embodiment, two nozzles, one of either side of the body and pointing forward.

In a preferred embodiment the rubber wiper blade is detachably mounted on the body, so allowing it to be replaced in case of wear.

In a preferred embodiment the handle is aligned substantially parallel to the forward to back axis of the scraper, that is substantially as right angles to the front scraping edge. In an alternative embodiment the handle is aligned substantially parallel to the forward scraping edge. In this way two variant embodiments are possible, depending on whether a user finds it more comfortable to use the scraper with their arm parallel to the forward scraping direction or at right angles to it.

The scraper is not limited to any specific size or shape, though the handle will generally be sides to fit a hand and the front scraping edge and rubber blade will be in general similar in size to existing scrapers.
