Abstract
The invention is directed to a can opener (1) having in its casing (2) a drive unit which is comprised of an electric motor (32) secured to a mounting plate (41), a gear train (33) and an output shaft (42) driving the drive wheel (17). The longitudinal axis (8) of the casing (2) along which the electric motor (32), the gear train (33) and the output shaft (42) are arranged forms with the direction determined by the input shaft (70) of the electric motor (32), the shafts (61, 62, 63) of the gear train (33) and the output shaft (42) of the drive wheel (17) an angle (a) which is smaller than 90.degree..
Claims12
A hand-held can opener for severing a lid from a can, comprising an elongated casing that defines a longitudinal axis, a drive wheel mounted on a shaft for rotation about a drive wheel axis, a cutter blade which is adapted to pivot about a cutter blade axis parallel to said drive wheel axis for operative association with said drive wheel, said casing having a working surface from which both said cutter blade and said drive wheel project, an electric motor arranged in the interior of said casing and having an output shaft that drives said shaft of said drive wheel through a gear train, said gear train including a series of spur gears, said electric motor, said spur gears and said drive wheel shaft being arranged along said longitudinal axis of said casing,
- said output shaft of said electric motor, the shafts of said spur gears and said shaft of said drive wheel extending parallel to each other, and said longitudinal axis of said casing forming an angle (a) smaller than 90.degree. with said shaft of said drive wheel.
