The invention concerns a shaving apparatus. In one non-exclusive aspect the invention concerns a shaving apparatus for use in body shaving, such as shaving the legs of a user.
It is customary in most Western countries for women to engage in leg shaving for aesthetic purposes. Among men, leg shaving is common among athletes who compete in cycling and swimming. Leg shaving can be undertaken with the use of either electrical or manual razors. A typical manual razor includes (i) a razor cartridge comprising one or more razor blades, and (ii) a transverse handle removably secured to the razor cartridge.
In human anatomy the functional position is widely understood to allow optimum function while offering maximum stability, control, strength and precision. The functional position of the wrist and hand is (i) wrist complex in slight tension (20°) and slight ulnar deviation (10°), and (ii) fingers moderately flexed at the metacarpophalangeal joints (45°) and proximal interphalangeal joints (30°). In facial shaving the wrist and hand will operate within those ranges. In the case of body shaving applications, however, the wrist and hand will operate well outside those ranges. A user manipulating the hand and wrist in such relatively awkward positions have significantly reduced control over the shaving razor.
It is an object of the present invention to provide an alternative shaving apparatus which addresses the drawbacks associated with body shaving using conventional shaving razors or at least to provide a useful alternative.
According to a first aspect there is disclosed herein a shaving apparatus including:
Preferably the user holding formation is operatively adapted to enable a user to hold the base in a hand of a user whereby the second, third, fourth and fifth metacarpals of the hand are substantially parallel with the razor cartridge located inside the cartridge opening.
Preferably the user holding formation is operatively adapted to secure the base to a plurality of fingers of the user such that the fingers of the user are substantially parallel with the razor cartridge located inside the cartridge opening.
Preferably the user holder formation co-operates with the base to define a first finger position and a second finger position respectively for receiving a first and a second finger of a hand of a user, the first and second finger positions being separated from one another by a divider of the user holding formation, the divider outwardly extending from the user holding face of the base.
Preferably the razor holding face includes an elongate first base member and a second laterally spaced apart and co-extending elongate second base member.
Preferably the cartridge opening is formed between the first and second base members.
Preferably the razor cartridge includes a cutting face and an opposing rear face, the cartridge opening being configured so that a gap is formed between the razor holding face of the base and the rear face of the razor cartridge secured in the cartridge opening.
Preferably the first and second base members define a cartridge holding formation to secure the razor cartridge within the cartridge opening.
Preferably the cartridge holding formation includes a first set of openings in the first base member and an opposing second set of openings in the second base member.
Preferably each opening of the first set of openings has a first shape while each opening of the second set of openings has a second shape, the configuration of the first shape being different to that of the second shape.
Preferably the user holding face of the base includes a gripping formation to facilitate purchase between the first and second fingers of the user and the base.
Preferably the gripping formation comprises (i) a plurality of protrusions outwardly extending from the user holding face of the base, or (ii) a plurality of recesses.
Preferably the divider includes a first wall and an opposing second wall, wherein the first and second wall curve inwardly to accommodate the first and second fingers of the user respectively.
Preferably the head is transversely orientated relative to the divider.
Preferably the base and the head in use cooperate to attach the shaving apparatus to the first and second fingers of a user.
Preferably the base and the head are adapted to cooperate to provide a three-point contact between each of the first and second fingers of the user and the shaving apparatus.
Preferably the head includes a shaving direction indicator.
According to a third aspect there is disclosed herein a razor cartridge operatively adapted for use with the shaving apparatus of the first and second aspect.
Preferred embodiments of the invention will be described hereinafter, by way of examples only, with reference to the accompanying drawings wherein:
The embodiment user holding formation 14 is operatively adapted to enable a user to hold the base 12. The embodiment user holding formation 14 is operatively associated with the base 12 and operatively adapted to enable a user to hold the base 12 in a hand in a manner whereby the second, third, fourth and fifth metacarpals of the hand are substantially parallel with the razor cartridge 31 located inside the cartridge opening 20. In the embodiment shaving apparatus 10 the user holding formation 14 is operatively adapted to secure the base 12 to a plurality of fingers of the user such that the fingers of the user are in a position which is substantially parallel with the razor cartridge 31 located inside the cartridge opening 20. In an alternative, non-illustrated embodiment the holding formation 14 is operatively adapted to secure the base 12 to a palm surface of a hand of the user.
The embodiment user holding formation 14 co-operates with the base 12 to define a first finger position 22 and a second finger position 24 respectively for receiving a first and a second finger of a hand of a user. The fingers may be those of either the right hand or the left hand of a user. The first and second finger positions 22, 24 are separated from one another by a divider 26 of the user holding formation 14. The divider 26 outwardly extends from the user holding face 16 of the base 12 and flares outwardly as shown. The divider 26 includes opposing divider edges 27. The divider edges 27 are operatively curved/shaped to allow for a comfortable fit in the web space between the first and second fingers of a user. The divider edges 27 are operatively adapted to position the razor cartridge on the user's hand to provide optimal use and further provides that the shaving apparatus 10 is ambidextrous.
The razor holding face 18 includes an elongate first base member 28 and a second laterally spaced apart and co-extending elongate second base member 30. The cartridge opening 20 is formed between the first and second base members 28, 30. The razor cartridge 31 includes a cutting face 33 and an opposing rear face 35. The embodiment cartridge opening 20 is configured so that a non-illustrated gap is formed between the razor holding face 18 of the base 12 and the rear face 35 of the razor cartridge 31 when secured inside the cartridge opening 20. The gap serves as a water channel to allow for the cleaning of cut debris from the shaving apparatus 10. It is further envisaged that the dimensions of the gap may be increased to provide for additional flexing of a razor blade held by the razor cartridge inside the cartridge opening 20.
It will be noted that outer edges 32 of the first and second base members 28, 30 are filleted. The reason for this is to allow for smooth passage of the shaving apparatus 10 across a user's skin.
