DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT INVENTION

[0041] The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description in combination with the drawings making apparent to those of skill in the art how the several forms of the present invention may be embodied in practice.

[0042] FIGS. 1 to 4 show a safety razor handle 2 in the form of an elongated body having an S-shaped configuration extending from a razor head end 4 to a free end 8. The razor head end 4 has a connecting structure 6 to which a razor head (such as the razor head 3 shown in FIGS. 5 to 9) is attachable. The elongated body has a lower surface 10 and an upper surface 12. Here, the term “lower surface” refers to that surface which is on the same side as the cutting edges of the blades when the razor head is connected to the razor handle (as shown in FIGS. 10 to 13). The term “upper surface” refers to that surface which is opposite to the lower surface.

[0043] Gripping areas are provided on the upper surface 12 of the handle 2. In particular, a first gripping area 14 and a second gripping area 16 are provided on the upper surface 12, spaced apart by a smooth area 18. The first gripping area 14 is provided by a plurality of arcuate protrusions 20 which are in the form of at least partial circles concentric with each other. Likewise, the second gripping area 16 is provided by a plurality of arcuate protrusions 22 which are in the form of at least partial circles concentric with each other. In this particular case, the first gripping area 14 has two arcuate protrusions 20 (the innermost of which forms a circle and the outermost of which forms a partial circle), and the second gripping area 16 has six arcuate protrusions 22 (the two innermost of which form circles and four outermost of which form two partial circles). Of course, a different number of protrusions is possible.

[0044] The concentric centers c1, c2 of the plurality of arcuate protrusions 20, 22 of the first and second gripping areas 14, 16 are aligned longitudinally along the central longitudinal axis (denoted by the dashed line in FIG. 3) of the razor handle. These concentric centers c1, c2 are spaced apart by about 2 cm along the central longitudinal axis of the razor handle (denoted by d1 in FIG. 3).

[0045] The smooth area 18 of the upper surface 12 which separates the first gripping area 14 from the second gripping area 16 extends continuously therebetween. The separation distance (denoted by d2 in FIG. 3) along the central longitudinal axis of the razor handle is about 1 cm in length.

[0046] The razor head end 4 of the handle 2 includes a pivot mechanism 54 that allows the razor head 3 to pivot back-and-forth in a plane perpendicular to the shaving plane P. The pivot mechanism can, of course, allow other pivoting motions such as side-to-side. In this particular example, the pivot mechanism 54 is an elastomeric member that surrounds the upper portion of the connecting structure 6 of the handle 2. The elastomeric member is surrounded by a generally circular rigid portion of the razor head end 4. As seen in FIG. 13, the razor head end 4 also arcuately bends away from the shaving plane P, to permit the cap 34 of the blade housing 30 to pivot backwards, i.e., to bend away from the shaving plane, over a large angular range.

[0047] The handle can be comprised of a rigid plastic and an elastomeric material disposed on rigid plastic. A majority of the upper surface 12 can be covered by the elastomeric material. For example, the elastomeric material can extend from the free end 8 of the handle 12 up to and including the pivoting mechanism 54 on the razor head end 4 of the handle 12.

[0048] FIGS. 5 to 9 show an exemplary razor head 3 that can be used in conjunction with the razor handle 2 shown in FIGS. 1 to 4. The razor head 3 includes a connecting structure 28, to engage with the connecting structure 6 of the razor head end 4 of the handle 2, and a blade housing 30. The blade housing 30 holds a plurality of blades 32 (five blades in this particular case) having respective cutting edges that lie in a shaving plane P. Thus, as used herein, the term “shaving plane” generally refers to the place in which the cutting edges lie. Although blade units are described in which four or five parallel blades lying in a shaving plane are provided, the blade housing may comprise more than five blades or fewer than four blades, i.e., the blade housing may comprise at least one blade. When more than one blade is provided, these do not have to lie in a shaving plane, for example the blades could be staggered. The blade housing 30 comprises a cap 34, including a lubricating pad 36, located behind the blades in a shaving direction s, and a guard 38, including a lubricating strip 40, located in front of the blades 32 in the shaving direction s, and side walls 42 connecting the guard 38 and the cap 34. As used herein, the term “shaving direction” signifies the direction in the shaving plane in which the blade unit is intended to be moved. The cap 34 and the guard 38 are connected by side walls 42. The connecting structure 28 of the razor head 3 includes a release button 44 to release the razor head 3 from the razor handle 2. As seen in FIG. 12, the release button 33 is aligned with the first and second gripping areas 14, 16 in the longitudinal axis. The release button 44 is mounted on an arm 46 which is resiliently bendable towards a fixed structure 48 of the razor head 3 when the release button 44 is pressed. In particular, when the user presses the release button 44 downwards, towards the cap 34 of the razor head 3, the arm 46 bends. The release button 44 has a downwardly extending projection 50 to abut an upwardly extending projection 52 of the fixed structure to limit the movement of the arm 46 when the release button 44 is pressed.

[0049] In use, the user can grasp the free end 8 of the handle 2 in the palm of their hand with ring and little fingers on the lower surface 10, thumb and middle finger on the sides 24, 26 of the handle 2 respectively (in a central region between the razor head end 4 and the free end 8), and index finger on the first or second gripping areas 14, 16.

[0050] FIGS. 14 to 17 show a protective cover 56 for the razor head 3 when it is not in use. The protective cover 56 is comprised of a plastic or polymeric material. The protective cover 56 comprises a base 58 and side walls 60 extending upwardly from the base 58. The side walls 58 are integral with one another and configured to surround the outer periphery of the cap 34, guard 38 and side walls 42 of the razor head 3. Both the base 58 and the side walls 60 can have cut-out portions in order to reduce the amount of material usage. The cover 56 can be placed on the razor head 3 from below, i.e., from a direction perpendicular to the shaving plane, while the razor head 3 is still attached to the handle 2.

[0051] The breadth and scope of the present invention should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents.
