Problems solved by technology

If the polishing pad is not attached exactly concentrically with the backing pad or its axis of rotation, respectively, the entire power tool will be subject to rather intense vibrations which are detrimental to proper long-term use of the power tool and can make working with the power tool even impossible

Embodiment Construction

[0033] Referring now to the accompanying drawings, figure 1 There is shown a hand-held power tool 1 according to the invention, suitable for use with a backing pad according to the invention and a polishing pad attached to the bottom surface of the backing pad. exist figure 1 A hand-held power tool 1 in the form of a random orbit polishing tool (or polisher) 1 is shown in FIG. The polishing machine 1 has a housing 2 substantially made of plastic material. The polisher 1 has a handle 3 provided at its rear end and a grip 4 provided at its front end. An electrical supply cord 5 having an electrical plug at its distal end exits from the housing 2 at the rear end of the handle 3 to provide electrical power to the electric motor and electronic control unit both located inside the housing 2 . At the bottom side of the handle 3 there is provided a switch 6 for activating and deactivating the electric motor of the power tool 1 . The switch 6 can be continuously held in its actuate...

Abstract

The invention relates to a hand-held power tool (1) comprising a plate-shaped backing pad (9) having a bottom surface (9a) and a polishing pad (11) for releasably attaching the polishing pad (11) to the top surface (11a) of the bottom surface (9a) of the backing pad (9). The power tool (1) also includes an electric or pneumatic motor adapted to drive the backing pad (9). In order to provide a simple and quick positioning of the polishing pad (11) relative to the backing pad (9), it is recommended that the bottom surface (9a) of the plate-shaped backing pad (9) comprises at least one protrusion(13a; 13b; 13c; 13d) that projects from the bottom surface (9a) ofthe backing pad (9), the top surface (11a) of the polishing pad (11) includes at least one corresponding recess (12a; 12b; 12c; 12d),and when the polishing pad ( 11) is attached to the backing pad (9), the at least one protrusion (13a; 13b; 13c; 13d) is received by at least one recess (12a; 12b; 12c; 12d).

Description

technical field [0001] The present invention relates to a polishing pad (or buffing pad) comprising a top surface for releasably attaching the polishing pad to a plate-shaped backing pad of a hand-held power tool, and a bottom surface. The surface faces the surface of the workpiece to be polished during intended use of the hand-held power tool. The backing pad (or liner pad) is actuated by the electric or air motor of a hand-held power tool in order to cause the backing pad to perform a pure rotary working motion, a random orbital working motion, or a rotary-orbital motion with the polishing pad attached to it homework movement. [0002] The invention also relates to a plate-like backing pad for a hand-held power tool, the backing pad comprising a bottom surface to which a polishing pad is releasably attached by its top surface. The backing pad is actuated by the electric or air motor of the hand-held power tool to cause the backing pad to undergo a pure rotational working m...
