POLISHING APPARATUS FOR FLAT AND BENT VEHICLE PANES

Abstract

The invention concerns a polishing apparatus (1), which has a very short handy and comfortable to handle construction with a very short length L. In order to reduce energy loss a direct vertical shaft (3) is used, which shaft (3) eccentrically drives the rotational head part (9). The special three legged support of the polishing apparatus (1) consists of the sanding or polishing disc (10) and two separately placed from each other adjustable support legs (11, 12). In this way flat and bent surfaces, such as vehicle panes, can be polished accurately and efficiently.

Claims

1. Polishing apparatus for flat and bent surfaces of massive and laminated glass, specific flat and bent massive and laminated vehicle panes, wherein said polishing apparatus has a short horizontal construction length because of a vertical structure of the polishing apparatus, wherein the polishing apparatus includes a housing a handgrip for manual operation, an electric motor having a driving shaft and a rotation head part, the handgrip for manual operation of the polishing apparatus, the driving shaft with the electric motor and the rotation head part provided with a polishing or sanding disc at the bottom being situated in a vertical axle, being the driving shaft, wherein the housing of the polishing apparatus is provided with a three legged support.

2. Polishing apparatus as in claim 1, wherein said threelegged support consists of a pair of support legs disposed at a distance with resect to each other and separately adjustable and as a third support the rotation head part with a polishing or sanding disc mounted thereon.

3. Polishing apparatus as in claim 1, wherein said rotation head part with electric motor or battery motor is driven said driving shaft, which is vertically oriented.

4. Polishing apparatus as in claim 1, wherein said rotation head part is driven pneumatically by said driving shaft.

5. Polishing apparatus as in claim 3, wherein said electric motor or battery motor is applied to an electronic speed regulator in order to obtain a constant rotational speed of the polishing disc.

6. Polishing apparatus as in claim 1, wherein said rotation head part is surrounded by a snap on conical tapered skirt part made of plastic in order to protect the fingers on the hand of the person using the polishing apparatus.

7. Polishing apparatus as in claim 6, wherein said plastic consists of a carbon fiber-reinforced nylon.

Description

[0013] The invention is further described by taking a preferred embodiment, indicated in the drawing, in which:

[0014] FIG. 1 is a side view of the polishing apparatus according to an embodiment of the invention;

[0015] FIG. 2 is a side view of the polishing apparatus over the line II-II in FIG. 1; and

[0016] FIG. 3 is a bottom view of the polishing apparatus over the line III-III in FIG. 1.

[0017] In FIG. 1 a side view of the polishing apparatus is indicated according to a preferred embodiment of the invention. The polishing apparatus has a very handy and practical short construction length L, which together with the structure or form of the polishing apparatus 1 provides a perfect fit in the hands 2 of the user and is relatively low in weight. The polishing apparatus 1 has an electrically driven shaft 3 with rotor 4 of the electric motor or engine 5. The electric motor 5 can be driven by means of a commonly used cable 5 or a battery, not indicated. Further a rotational regulator 7 can be provided in order to guarantee a constant and high-quality polishing job. To put the apparatus into motion a switch 8 can be used. Said shaft drives eccentrically the rotation head part 9. The eccentric head part 9 at the bottom is provided with a polishing or sanding disc 10. Furthermore another pair of separately adjustable support legs 11 and 12 are provided, so the polishing apparatus 1 has a three legged support 10, 11, 12 placed e.g. on the laminated vehicle pane 13 which is to be polished. Furthermore the polishing apparatus in order to protect the fingers of the hand 2 is provided with a snap on conically tapered skirt part 14. Than the separately adjustable support legs 11 and 12 are provided with a rubber support foot 15 and 16.

[0018] In FIG. 2 a side view of the polishing apparatus 1 is shown over the line 11-II.

[0019] In FIG. 3 a bottom view of the polishing apparatus 1 is shown over the line III-III. Similar parts are indicated with the same position numbers.

[0020] Finally, it has to be emphasized that above a preferred embodiment of the invention has been described and that further modifications and such are possible without leaving the scope of this patent specification.
