Description:
STYLUS RAZOR

DESCRIPTION

The present invention refers to a stylus razor to provide beard and/or haircuts or similar cuts providing such a level of detail to define images, symbols or other decorations obtained via hair having different lengths.

The scope of the present invention is to provide a razor capable of simplify the cut in particular in the refining phase of the decoration applied to a beard and/or hair.

The scope of the present invention is achieved by a razor according to claim 1.

The present invention will be described herein with reference to the attached drawings that show non-limiting embodiments, wherein:

- Figure 1 is an exploded lateral view of a stylus razor according to the present invention;

- Figure 2 is a cross section view along line II-II in figure 1;

- Figure 3 is a plan view of a razor blade for the razor in figure 1;

- Figure 4 is a lateral view of a tool associable to the razor in figure 1;

- Figure 5 is a lateral view of a cap for the razor in figure 1; and

- Figure 6 is a cross section view along line VI-VI in figure 5. Figure 1 shows as a whole a stylus razor comprising an elongated body 2 defining a preferably knurled handle 3 and a funnel neck 4 releasably connected to a head portion 5 of elongated body 2. In particular, head portion 5 is distal from handle 3 and, in the non-limiting embodiment in figure 1, is coaxial to an axis A of handle 3 and/or of elongated body 2. Furthermore, it is possible that elongated body 2 be of a different shape than that shown in the figures, e.g. have a slightly curved shape or another ergonomic shape.

Preferably, funnel neck 4 is hollow and elongated, e.g. along axis A, and defines a through opening 6 distal from handle 3 when funnel neck 4 is attached to head portion 5 and a coupling portion 7 longitudinally opposite to through opening 6. Advantageously, coupling portion 7 is threaded or defines a bayonet coupling.

Furthermore, head portion 5 comprises, preferably in a single body, a stop 8 housed in funnel neck 4 when the latter is attached to elongated body 2.

Stylus razor 1 further comprises a flexible blade 9 (figure 3) demountably coupled to in funnel neck 4 against stop 8 so that a curved portion 10 defining a curvilinear cutting edge projects from through opening 6 when funnel neck 4 is mounted on head portion 5. In particular, flexible blade 9 comprises a first and a second branch 11, 12 connected one another by curved portion 10 and contacting stop 8 when funnel neck 4 is mounted so as to oppose the retraction of the curvilinear cutting edge towards handle 3. Therefore, in use, curvilinear cutting edge of curved portion 10 provides particularly precise beard and/or haircuts and precisely delimits areas with longer hair and areas with shorter hair. Indeed, the substantially arched or bridge shape of curved portion 10 allows to precisely see the cutting zone and to evacuate hair after the cut.

According to a preferred embodiment, stop 8 comprises an elongated stem 8a, preferably along axis A, which, when housed in funnel neck 4, defines with the latter a toroidal interstice suitable for housing and deforming, in particular elastically deforming, at least one of first and second branch 11, 12. Advantageously, stop 8 contacts braches 11, 12 in a transversal direction to that of elongation to cause a deformation of braches 11, 12 towards a tapered lateral wall 13 of funnel neck 4. Caused by such a contact, a friction action is defined on branches 11, 12 to oppose the retraction of curved portion 10 towards handle 3 in use. In alternative or in combination, stop 8 also comprises a step 14 from which stem 8a projects and where at least one of branches 11, 12 has a butt contact to block the displacement along a substantially parallel direction to that of elongation of stem 8a.

Stem 8a further comprises an end portion 15 distal from handle 3 and having a transversal dimension such to fit in through opening 6 to demount the flexible blade when funnel neck 4 is demounted. In such a condition it is indeed possible that the flexural elastic action of curved portion 10 on branches 11, 12 cause a friction action on wall 13 such that flexible blade 9 cannot disassemble from funnel neck 4 due to the action of the acceleration of gravity.

Figure 4 shows a manual blade-pushing tool 20 to mount flexible blade 9 in funnel neck 4. Tool 20 comprises a tip 21 that can be housed in funnel neck 4 to push flexible blade 9, in particular curved portion 10, so that the latter projects from through opening 6 when funnel neck 4 is demounted from head portion 5. In particular, a transversal dimension of tip 21 is such to fit in through opening 6 when introduced in funnel neck 4 through coupling portion 7.

Furthermore, tip 21 projects with respect to a base 22 defining an abutment 23 arranged transverse to tip 21 and contacted by funnel neck 4 when tip 21 projects through the through opening 6 to position flexible 1 in such a way that curved portion 10 be projecting. In such an abutting condition, tip 21 has a length such to project from through opening 6.

Furthermore, length of tip 21 and branches 11, 12 is such to push the blade beyond coupling portion 7 along the longitudinal direction such to avoid interference when funnel neck 4 is screwed or bayonet coupled.

When funnel neck 4 is screwed to head portion 5, a compressible spacer 30 is provided, e.g. an o-ring (figure 1), placed between funnel neck 4 and a shoulder 31 of head portion 5 such that a user can adjust the projection of curved portion 10 from through opening 6 by screwing or unscrewing funnel neck 4. In particular, step 14 is opposite to handle 2 with respect to shoulder 31.

A selling kit of razor 1 may comprise also tool 20 and/or one or more flexible blades 9.

Figures 5 and 6 show a cap 30 releasably mountable, e.g. as a friction press cap or as a snap cap, on stylus razor 1 to define a safety device when flexible blade 9 is mounted and to avoid possible injuries and/or cuts due to curvilinear cutting edge.

Furthermore, it is possible that modifications or changes are applied to the stylus razor of the present invention without departing from the scope of protection defined by the attached claims.

Elongated body 2 preferably has a circular cross section so as to be easily manufactured by lathing. Other shapes are however possible, such as a polygonal shape, and other manufacturing technologies such as injection molding if elongated body 2 is of a polymeric resin.
