Abstract
An electrical supply apparatus particularly for hand-tools, in the form of a housing having a handle at its upper end and a bottom constituting a skid, the housing having a vertical, longitudinal median plane along which the skid bottom is elongated. An electrical cable can be wound in a recess above this bottom and emerges from an opening below the center of gravity of the apparatus by being connected to the housing by a stress relief. The curvature of the skid is greater in the longitudinal direction than in its transverse direction.
Claims4
An electrical supply apparatus for hand-tools or the like, comprising:
- an upright housing having a downwardly convex bottom elongated in one direction to form a runner extending in said direction, said housing being formed with a handle at its upper end, said housing having an outwardly open annular recess above said runner, said bottom having a greater curvature in a vertical median plane in said direction than transversely to said plane, said housing being formed with an opening in said plane and in said recess at a level not substantially above the center of gravity of the apparatus;
- a battery in said housing;
- a cable running to said battery extending out of said housing through said opening for connecting the apparatus to a hand-tool or the like, said cable being adapted to be coiled in said recess;
- and
- cable-tension relief means connecting said cable to said housing.
