Manual Shaving Razor
This invention relates to a device to allow a manual razor blade to rotate in a controlled manner within various degrees of freedom in relation to a handle whilst in use.
Background
When shaving, it has become accepted that a closer shave can be had if more blades are added to a unit or blade cartridge is able to swivel, following the contours of the skin.
However, conventional razor head blades are either fixed head, or swivel in one position, (forward and backwards, usually parallel to the blad
There is a risk that the razor does not maintain even contact and pressure over the length of the blade. This results, not only in an inconsistent quality of shave, but could also result in poor shave comfort and even abrade the skin.
If the blade head is unable to rotate on the handle in any other than one axis, the pressure of the blade on the skin is less controllable, resulting in an uneven shaving experience.
In attempts to overcome these problems, various razors have been proposed that have a shaving blade head which rotates in some fashion relative to the handle, allowing some movement in addition to the now common swivel feature. These razors can either be pre-set by the user and locked in a position for use, or allow movement during use by employing a complicated, impractical or expensive mechanism.
The joints between the handle and the blade head in these razors is formed by use of common systems or mechanisms, for example (but not limited to); a ball joint, a universal joint, a spigot fitted to a spherical bush, a live hinge, or a combination of linear axes.
However it is still preferable that the blade head should not be able to rotate in an uncontrollable fashion, in which case the blade could not present to the skin at an inappropriate angle.
Statement of Invention
This invention concerns a manual shaving razor handle comprising a spheroid articulation of the blade hood on the handle to provide freedom of movement in roll pitch and yaw and any combination there of when in use wherein the articulation is damped by one or more flexible elastic connections between the handle and the blade head.
The invention, and its variants, will now be described solely by way of example and with reference to the accompanying drawings in which;
Figure 1 is a side elevation showing of the invention featuring an articulated joint between the handle and the blade head, and a flexible membrane or hood
Figure 2 is a rear elevation of the invention showing a handle and a flexible membrane or hood
Figure 3 is a sectional side elevation showing the invention, featuring a ball and socket joint between the handle and the blade head
Figure 4 is an isometric view of the invention, from the front and below featuring a variant of the invention using a flexible membrane or hood
Figure 5 is an isometric view of the invention, from the back and above featuring a variant of the invention using a flexible membrane or hood
The following description can be read in relation to each of the figures listed above
A handle (1) is attached to a blade head (2) by means of a joint which might be a ball and socket joint (4) or a live hinge - The blade head (2) not only carries a blade cartridge (3) but also is attached to the flexible hood (6) the bottom of which is attached to the handle (l).The handle (1) or blade head (2) may also include a buffer feature (11), to limit articulation.
Claims
1. "A supple/flexible hood as in figure 1 (point 6) which connects a manual shaving handle to a suspended blade head figure 1 (point 2) to allow movement of the blade head in a controlled manner
