BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an apparatus for cleaning the inner surfaces of the front and rear windows of automobiles.
2. Description of the Prior Art
Numerous scrapers and wipers for cleaning the exterior surfaces of automobile windows are known. They consist of a handle and a cleaning part fixedly connected thereto, for example a scraper, wiper blade or foam rubber strip, or combinations thereof.
In most cases, such cleaning devices must be capable of removing dirt, caked on the exterior surface of the window, by exerting a mechanical force and subsequently drying the cleaned, wet window. It is accordingly necessary to be able to exert a directed force effect on the cleaning part through the handle in order to be able to achieve a directed scraping action. Based on these considerations, the connection between the handle and the cleaning part is provided as a rigid one.
None of these considerations are valid in regard to cleaning the insides of the automobile windows. Here, no great pointed or linear pressure is required, only a flat, steady, but reduced pressure. Accordingly, the cleaning part should not be rigid per se, but flexible, and the connection between the handle and the cleaning part should be as movable as possible. Only in this way is it possible to clean the concavely-shaped and extremely hard to reach inside surfaces of automobile windows.
SUMMARY OF THE INVENTION
Based on the above considerations and experiences, a device for cleaning the inside surfaces of the windshield and rear window of an automobile having a cleaning part disposed on a handle, the cleaning part in the form of a plate which is connected with means for the removable connection of an exchangeable knuckle joint to the handle has been developed which eliminates the disadvantages of known devices and is particularly suited for cleaning the inside surfaces of automobile windows.
In accordance with one embodiment of this invention, the plate is curved such that its contact surface has a concave, cylindrical bend, the axis of curvature of which extends perpendicular to the longitudinal axis of the plate.
In this way the free adaptability of the inclination of the cleaning part relative to the handle is assured on the one hand while the rotational position of the cleaning part relative to the longitudinal axis of the handle is retained.
To achieve an even and flat cleaning of the inside surface of the automobile window, in accordance with one embodiment of this invention, means for the removable fastening of the cleaning part in the form of claw-like hooks are distributed over the surface thereof.
BRIEF DESCRIPTION OF THE DRAWINGS
Further advantages of the subject invention will be apparent from the following description in conjunction with the drawings wherein:
FIG. 1 is a perspective view of the device for cleaning the inside surfaces of the windshield and rear window of an automobile in accordance with one embodiment of this invention;
FIG. 2 shows a detail drawing of the hinged connection between the cleaning plate and the handle in accordance with one embodiment of this invention; and
FIG. 3 is a perspective view of a cleaning plate for fastening a cleaning cloth in accordance with one embodiment of this invention.
DESCRIPTION OF PREFERRED EMBODIMENTS
The device for cleaning the inside surfaces of the windshield and rear window of automobiles in accordance with one embodiment of this invention comprises two parts, namely a handle 1 and a cleaning part 2, which are movably connected to each other by a knuckle joint 5. The cleaning part comprises a plate 3, means 4 for the removable fastening of a cleaning cloth, and the cleaning cloth 6 itself. It is essential for cleaning the windshield, in particular, that the driver can clean it quickly and cleanly using the device of this invention. The exchangeability of the cleaning cloths 6 assures cleanliness. It is essential for quick cleaning that the cleaning part 2 is connected in a limitedly movable manner to the han
