Safety razor
Abstract
PURPOSE: To smoothly rock an assembled blade body with simple constitution by fitting an elastic member on the rear side surface of an assembled blade body as a means for recovering the rocking of the assembled blade body to be in press contact with a recessed part formed for the holder of a projection part formed on this elastic member. CONSTITUTION: A recessed part 11 recessed nearly in a chevron form is formed in the center of the head part 10 of the holder 2. The projecting part 9 of the elastic member 1 is elastically in press contact with this recessed part 11. The holder 2 is provided with a pair of arms 14 and 14 in one body on its upper part and an inward journal shafts 15 and 15 are arranged at the tip part of the arms 14 and 14. Then, when the part 9 exists in the inner depth of the part 11, the assembled blade body 1 is at a neutral position. When force rocking the body 1 upward is added to the body 1, an elastic member 7 is deformed and its projecting part 8 is moved toward the lower surface of the part 11. When force added to the body 1 is released, the part 9 is returned to the inner depth of the part 11 by the elasticity of the member 7 and the body 1 is also recovered to an original position linked with the body 1.

[Detailed Description of the Invention]
(Field of the Invention) The present invention relates to improvement of a safety razor. (PRIOR ART) The safety razor provided with the means for returning the assembly blade which the assembly blade attached to the holder rocked and rocked from the former focusing on the axis prolonged in the longitudinal direction to the original position existed. However, the returning means of the assembly blade of elegance was formerly the structure of it being supported by the spring, having formed a movable pusher in the up-and-down direction, having established the cam surface of "<" type in the back of an assembly blade, and welding a pusher by pressure to the head of a holder in a cam surface. However, conventionally [ this ], in elegance, the pusher had to be built into the head of a holder and there was a fault that structure changed too much intricately. (Problem which an invention tends to solve) The present invention removes the fault of elegance conventionally which was mentioned above, and an object of the present invention is to provide the safety razor which can rock an assembly blade smoothly with a simple structure. (Means for solving problem) The constitution of this invention is explained while referring to drawings. A safety razor comprises assembly blade 1 and holder 2. To holder 2, focusing on the rocking axis prolonged in the longitudinal direction, assembly blade 1 is attached so that rocking is possible. Assembly blade 1 is what carried out fastening fixation of the blades 5 and 5 of two sheets between tool post 3 and top plate 4, and spacer 6 intervenes among blades 5 and 5 of two sheets. A pair of ribs 12.12 are provided in the back of an assembly blade at one, and journal bearing 13*13 is drilled by each rib 12.12. Cantilever elastic member 7 for returning rocked assembly blade 1 to the original position flexibly is provided in the center of the back of assembly blade 1. Elastic member 7 is prolonged in the direction of an edge of another side from near [ longitudinal direction edge 8 ] assembly blade 1. Elastic member 7 can bend in a safety razor in the up-and-down direction of opposite Perilla frutescens (L.) Britton var. crispa (Thunb.) Decne. Downward projected part 9 is provided in the end of elastic member 7. Crevice 11 dented to Hub "<" type is prepared for the husband in head 10 of holder 2. Projected part 9 of the above-mentioned elastic member 1 is welding by pressure to this crevice 11 elastically. As for holder 2, a pair of arms 14.14 are provided in one at the upper part, and journal axis 15.15 for inner is provided in the end of arm 14.14. (OPERATION) When the above-mentioned projected part 9 is contained in solid [ of crevice 11 ], assembly blade 1 is in a neutral position. When the power of making assembly blade 1 rocking upward is added to assembly blade 1, elastic member 7 bends, and the projected part 8 is moved to the direction of the undersurface of crevice 11. When the power in which it was added to assembly blade 1 is released, projected part 9 returns to solid [ of crevice 11 ] with the elasticity of elastic member 7, assembly blade 1 also interlocks, and it returns to the original position. On the contrary, when the power of turning assembly blade 1 downward to assembly blade 1 is added, projected part 9 contacts the upper surface of crevice 11, and if power is released, it will return. Numerals 16 are the rocking restriction projection of assembly blade 1, and it makes the operation which regulates that stop on arm 14.14 and more than an angle with constant assembly blade 1 rocks. (EFFECT OF THE INVENTION) The present invention has the above composition, holder 2 is equipped with assembly blade 1, and rocking of it is attained focusing on a journal axis. Since rocked assembly blade 1 returns according to the elastic power of elastic member 7, it will repeat rocking corresponding to unevenness of the surface of a face at the time of shaving. The feature of the present invention is elastic member 7 by which a means for returning rocking of assembly blade 1 was provided in the back of assembly blade 1. It is eventually made to return using the elasticity of elastic member 7 by welding by pressure projected part 9 provided in this elastic member 7 to crevice 11 provided in holder 2. As elegance was conventionally mentioned above, it had become a complicated structure, but this invention is an outstanding invention which can provide the product which has an assembly blade smoothly rocked with a simple structure. Since elastic member 7 has the feature in the place used as the cantilever elastic piece prolonged to the perpendicular direction of assembly blade 1, rocking of an assembly blade is conventionally smooth compared with elegance.
