Benefits of technology

[0006] It is an object of the present invention to provide an easily operated handheld power tool such as a buffer or a polisher.
[0015] The present invention has the advantage that during buffing of a workpiece, the operator's wrists need bend to only a small degree to accommodate the non-parallel disposition of the buffing member and the handle. The pressure applied to the operator's arm is substantially in the same direction as that applied by the main housing to the workpiece leading to labour efficiency and reduced wrist tiredness.

Problems solved by technology

The pressure applied to the operator's arm is substantially in the same direction as that applied by the main housing to the workpiece leading to labour efficiency and reduced wrist tiredness.

Embodiment Construction

[0047] Referring to FIGS. 1 to 3, 5 and 7, an embodiment of the handheld power tool of the invention includes a main housing 2, a rear handle 8 which is mounted on the main housing 2 and an annular handle 10 which is connected to (and around) the main housing 2. The main housing 2 houses the driving mechanism and has a buffing member 6 in the basal plane. The rear handle 8 has a substantially C-shaped configuration and extends axially from the main housing 2.

[0048] The annular handle 10 is shown in isolation in FIG. 8 and comprises two oppositely disposed side handle members 1 and a front handle member 4 which joins the front end portions of the two oppositely disposed side handle members 1. The front end portions of the two oppositely disposed side handle members 1 are smoothly interconnected with the side end portions of the front handle member 4. The two oppositely disposed side handle members 1 are tilted gradually upwardly with respect to the basal plane from rear to front. Th...

Abstract

The present invention relates to a handheld power tool including: a main housing, a rear handle mounted on the main housing and a handle connected to the main housing. A base portion of the main housing has a buffing member in the basal plane. The handle comprises two oppositely disposed side handle members and a front handle joined between the front end portions of the two oppositely disposed side handle members. The two oppositely disposed side handle members tilt (ie are non-parallel) with respect to the basal plane. The present invention has the advantage that during buffing of a workpiece, the operator's wrists need bend to only a small degree to accommodate the non-parallel disposition of the buffing member leading to labour efficiency and reduced wrist tiredness.

Description

CLAIM OF PRIORITY [0001] This application is a continuation application of U.S. patent application Ser. No. 10 / 760,128 filed Jan. 16, 2004 and claims priority under 35 U.S.C. §119 to Chinese Patent Application No. 03219560.5 filed Jan. 24, 2003, which are hereby incorporated herein by reference in there entirety.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a handheld power tool such as a buffer or a polisher. [0004] 2. DESCRIPTION OF THE RELATED ART [0005] Conventional handheld power tools for buffing or polishing comprise a main housing, a rear handle mounted on the main housing and a handle connected to the main housing. The handle adopts a substantially circular configuration. A base portion of the main housing has a buffing member in the basal plane. The handle and the basal plane of the buffing member are parallel. During the buffing of a workpiece, the operator's wrists bend to a large degree to accommodate the parallel d...
