Abstract: Battery operated appliances are provided. Some appliances include a housing defining a chamber having an interior wall, electronics within the chamber, a battery cover, and a closing system including (a) a first electrically conductive member secured to the battery cover, and (b) a second electrically conductive member secured to the interior wall of the housing and configured to engage the first electrically conductive member and thereby mechanically secure the battery cover to the housing while also establishing electrical contact between the first and second electrically conductive members.

Abstract: This new electric razor has a set of multiple shaving knives (12), having dual cutting edges longitudinally on both sides of knife, and rotating and reciprocating simultaneously on the inner surface of a cylindrical shaving screen (11). This mechanism creates a 3-dimensionally elliptical motion of the shaving knives that effectively slices hair off (not chopping) and provides a smooth and comfortable shave with minimum skin irritation. The cylindrical shaving screen (11) and the main body (19) containing a rotating cup (16), a motor (17) and power source (18) forms an inherently ergonomic, angled shape, which is also slim and compact overall for convenient use and easy carrying. This razor has a 360 degree effective shaving screen surface and can be used in wet or dry environments. Cleaning the shaving head screen requires no disassembly and can be done easily under running water.

Abstract: A razor assembly is provided that includes a razor cartridge with one or more razor blades, a shaving aid body, a handle, and a linkage pivotally connected to the handle. The linkage is connected to the razor cartridge and the shaving aid body in a manner such that the razor cartridge and the shaving aid body are moveable relative to the handle. Movement of one of the razor cartridge or the shaving aid body in a first direction causes the other of the razor cartridge or the shaving aid body to move in a second direction substantially opposite the first direction. As a result, the positions of the shaving aid body and the razor cartridge are continuously adjusted to maintain the contact surface of the shaving aid body approximately co-planar with the cutting edges of the razor blades within the razor cartridge.

Abstract: A shaving implement is provided that includes a replacement cartridge mounted to a handle. The replacement cartridge includes a shaving aid body and a razor cartridge. The shaving aid body can be erodible and the handle is provided with a self-leveling mechanism to relatively maintain a generally coplanar relation between the top surface of the shaving aid body and the shave plane of the razor cartridge during a normal shaving operation as the shaving aid body erodes during use. The shaving implement is provided with limited pivotal motion of the replacement cartridge relative to the handle about three generally mutually perpendicular axes and combinations of the three axes. Biasing force is provided to urge the replacement cartridge to a neutral position relative to the three axes.

Abstract: A shaving device includes an assembly to better maintain the cutting blades in contact with the skin during shaving. A swivel ball joint is preferably located between the shaver head and the housing and enables the head of the shaver to move in any direction from a longitudinal axis through the shaving device. A positioning spring connected to the ball joint and the housing is biased toward the center axis of the shaver and provides a swivel action that causes the shaver head to return back to its center position after adjustment of the head's angle. A motion transfer spring transfers the motor action to the upper shaving mechanism at any angle or direction that the shaver head may be in at any time. As the shaver head changes angles to match the contour of the user's body, the motion transfer spring flexes to follow the angles of the shaver head. This transfers the motion of the motor to the eccentric cam, which helps to control the motion of the trimmers.

Abstract: In a shaving implement a handle is provided that includes a body section and an end portion projecting outwardly therefrom. An axle member is rotatably coupled to the end portion for selective angular movement relative thereto. A razor cartridge is coupled to the axle member and includes at least one razor blade that defines an at least partially exposed cutting edge. The razor cartridge is rotatably moveable with the axle member and the detent is provided for releasably retaining the axle member and thereby the razor cartridge in the user selected angular position relative to the handle.

Abstract: In-line razor-blade shaving devices feature two sets of razor blade strips pointing inwardly in opposite directions. The devices are designed for safely and rapidly shaving hair from large body portions such as legs and arms. Each device features an elongated handle arranged in line with an elongated bi-directional razor blade head. Each set of razor blade strips in the head may be provided with one or more straight razor-sharp edges, which point in the same direction, while the blade edges of the two sets point inwardly toward from one another, generally in opposite directions. The edges of blade strips of the two sets may be arranged in one common working plane, or each set may be in its own working plane, with the planes at an angle to one another. The working planes are defined by the elongated front and rear guard surfaces of the blade-edge guarding system on the face of the razor head. These guard surfaces contact a user's skin before and after the razor-sharp edges to help ensure safe shaving.

Abstract: A pounding head is mounted onto a handle at an offset with respect to the handle in order to align the pounding head with the forearm. In the preferred embodiment, this offset is defined by an angle &bgr; created between a first reference plane extending through the axial center of the pounding head and bisecting the pounding head and a second reference plane extending through the axial center of the handle, bisecting the handle along its front and rear portion.
