Abstract
A can opener (100) comprising a pair of handles (10 and 11), a traction wheel (13) and a cutter blade (14) for removing a lid of a can in the conventional laterally-cutting manner. Embodiments of the invention include an operating knob (16) that is supported, at one side (right side as shown) of the can opener (100), to rotate about an axis transverse to a central axis of the can. The knob (16) is coupled by means of step-down gearing (17 and 18) to the traction wheel (13). This construction renders the use of the can opener (100) much more comfortable for a user. For left-handed use, the knob (16) is fitted to the opposite (left hand) side of the can opener.
Claims16
A can opener of the laterally-cutting type, comprising a pair of operating members pivotal with respect to each other, one said member mounting a rotatable traction wheel and the other said member a rotatable cutter blade, said wheel and said blade being movable between an inoperative position in which said wheel and said blade are spaced apart to an extent that the rim of a can to be opened is locatable between said wheel and said blade, and an operative position in which said wheel and said blade are in close proximity and engageable with a said can to effect opening thereof, in which the traction wheel and the cutter blade have respective rotational axes which in use are substantially parallel to a central axis of a said can, and including a housing formed on said one member, an operating element provided on one side of the can opener and supported by the housing and arranged to rotate about an axis generally transverse to the central axis of a said can, and gearing provided in the housing mechanically coupling the operating element to the traction wheel.
A can opener of the laterally-cutting type, comprising a pair of operating members pivotal with respect to each other in use about a substantially vertical axis, one said member mounting a rotatable traction wheel and the other said member mounting a rotatable cutter blade, said wheel and said blade being movable between an inoperative position in which said wheel and said blade are spaced apart to an extent that the rim of a can to be opened is locatable between said wheel and said blade, and an operative position in which said wheel and said blade are in close proximity and engageable with a said can to effect opening thereof, and including a housing formed on said one member, an operating element provided on one side of the can opener and supported by the housing and arranged to rotate about an axis generally transverse to the central axis of a said can when the opener is in use on said can, and gearing provided in the housing mechanically coupling the operating element to the traction wheel.
A can opener of the laterally-cutting type, comprising a pair of operating members pivotal with respect to each other in use about a substantially vertical axis, one said member mounting a rotatable traction wheel and the other said member mounting a rotatable cutter blade, said wheel and said blade being movable between an inoperative position in which said wheel and said blade are spaced apart to an extent that the rim of a can to be opened is locatable between said wheel and said blade, and an operative position in which said wheel and said blade are in close proximity and engageable with a said can to effect opening thereof, and including a housing formed on said one member, and an operating element provided on one side of the can opener and supported by the housing for rotating the traction wheel, said one side of the opener being the left side to a user when the opener is used on said can by said user, said element being rotatable about an axis extending at an angle in the range of 45° to 90° downwards from the rotational axis of the traction wheel.
