ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a winch drive, particularly for a boat or yacht.
2. Description of Related Art
Winches are commonly used on yachts or other boats for tensioning or pulling running rigg, usually a line wound around the drum of the winch. The winch is normally rotated manually, and a standard shaped socket is provided in the top of the winch into which the correspondingly shaped end of a handle is inserted. Rotation of the handle rotates the winch and tensions the line. Manually rotating the winch can be difficult work, particularly under certain conditions, eg with heavy load and/or in bad weather.
It is known to power some forms of winch by means of an electric motor situated below deck immediately under the winch. Such a motor takes up valuable under-deck space, and can be difficult to access for servicing.
SUMMARY OF THE INVENTION
An object of this invention is to provide a winch drive, which is simple to operate and does not occupy under-deck space.
The invention provides a winch drive as claimed in claim
1
.
Although the shaped bit may be retractable, it is preferably integral with the power tool.
Preferably, the power tool is battery driven, and the batteries are rechargeable. The batteries may be accommodated within a handle of the power tool or in a separate detachable battery housing.
