Embodiment Construction

[0030] The present invention fulfills the need for a hand-held device having a head unit capable of pivotal movement about a pivot axis and rotational movement about a rotation axis, said device being suitable for use as a hair removal device. Removal device: providing a handle comprising a gripping portion and a connecting portion that rotates relative to the gripping portion about an axis of rotation, wherein the gripping portion and connecting portion are connected by a rod comprising a non-rotatably attached Attached to the distal end of the gripping portion and non-rotatably attached to the proximal end of the connecting portion, wherein the axis of rotation forms the central longitudinal axis of the rod, and wherein the connecting portion is formed to accommodate an optional head unit such as a blade A docking portion of the unit, the docking portion being positioned oppositely away from the rod and / or the gripping portion.

[0031] Attached non-rotatably, as defined her...

Abstract

A hand held device comprising: a handle, said handle comprising a grip portion and a connection portion, said connection portion rotating with respect to said grip portion about a rotational axis, said connection portion forming a docking portion suitable for receiving an optional head unit, said docking portion being positioned opposite distally away from said grip portion, wherein the grip portion and the connection portion are connected by a rod, said rod comprising a distal end non-rotatably attached to the grip portion and a proximal end non-rotatably attached to the connection portion, wherein rotational axis forms a central longitudinal axis of said rod.

Description

Background technique [0001] Some handheld devices, such as safety razors, have a head unit (such as a blade unit) connected to the handle for pivotal movement about a single pivot axis. The pivot axis is substantially perpendicular to the long axis of the handle itself. When the device is a safety razor, the single pivot axis may also be substantially parallel to the blade (ie the cutting edge). For a safety razor, pivotal movement about a single axis provides a degree of conformity to the skin, allowing the blade unit to easily follow the contours of the user's skin during shaving. A pivot axis extending generally parallel to the edge of the blade may be defined by a pivot structure at which the handle is connected to the blade unit. Safety razors of this type have been successfully marketed for many years. However, due to the limited mobility of the blade unit to pivot about a single axis, the blade unit often becomes dislodged from the skin during shaving. [0002] In o...
