Hereinafter, the present invention will be described with reference to the accompanying drawings for each embodiment, focusing on the above-described angle adjusting structure and the fastening structure therefor, with respect to which specific forms each angle adjusting unit can be implemented.

[First Embodiment - Structure of Figs. 1 to 3]

Referring to FIGS. 1 to 3 , according to the first embodiment of the present invention, an example of an angle adjustment type razor utilizing a friction and holding structure of a symmetrical gearwheel method is shown.

That is, through-holes are formed at coupling portions where the head portion 110 and the body portion 120 are mutually coupled (refer to the head coupling portion 112 and the body coupling portion 122 in FIG. 2), respectively. A predetermined fastening means for fastening through a hole (a screw screw method (see reference numbers 114A and 114B in the case of FIG. 2A), a rivet coupling method (see reference number 115) in the case of FIG. 2 (B), in addition to Various fastening means and methods may be applied) are applied. At this time, symmetrical gearwheels are protruded from each coupling surface where the head coupling part 112 and the body coupling unit 122 are coupled face-to-face, so that the head unit 110 is formed through the symmetrical gearwheel structure. ) and the relative angle change (adjustment) between the body portion 120 becomes possible.

In addition, at this time, although the protruding directions of the gear wheels to be formed for face-to-face coupling of the head coupling portion 112 and the body coupling portion 122 may be manufactured so as to face each other, the protrusion direction of the gear wheels When formed to be obliquely inclined (that is, the mountain of the gearwheel is formed to be inclined in one direction), it may be a convenient structure to rotate the head part 110 only in one direction.

In addition, the razor blade to be provided in the head unit 110 has a fixed blade angle for use, so that the angle adjustment of the head unit 110 is in an unintended direction (normal rotation direction to be rotated to suit the original shaving purpose and If it is bent in the opposite direction), it may be difficult to use because the angle of the blade does not match, so as shown in FIG. By making a rotation prevention jaw (see reference number 122L in FIG. 3) or a guide at one side end of the part to be made, it can be rotated only in the forward rotation direction.

[Second Embodiment - Structure of FIGS. 4 to 6]

Referring to FIGS. 4 to 6 , according to the second embodiment of the present invention, an example of an angle adjustment type razor using ball joint type friction is shown.

That is, a joint fastening part is formed on one side of the head part 110 so that the joint part of the ball joint 116 is detachable (in the case of FIG. 5, the joint part of the ball joint is formed with a screw screw, and one side of the head part 110 The joint fastening part of has a groove to which the screw can be coupled, but various other coupling methods are possible as well as a form in which the joint part of the ball joint is integrally fixed to one side of the head part 110 is also possible. ), the ball head 116A or 116B of the ball joint 116 is seated in the body coupling portion (refer to reference numeral 122B in FIG. 6) corresponding to the coupling portion to be coupled with the head portion 110 in the body portion 120 Since the seating groove to be coupled is provided, the ball head 116A or 116B and the seating groove can be relatively rotated while stiff friction occurs, so that the angle of the head portion 110 can be adjusted.

At this time, the ball head of the ball joint 116 may be basically manufactured in the form of a spherical head as shown in FIG. 6 (B), but in the form of a cylindrical head that follows the direction of rotation as shown in FIG. 6 (A) It may be manufactured, and although not shown through the drawings, the holding force by friction may be further improved by being manufactured as a ball head in the form of a polyhedron. At this time, of course, the seating groove is manufactured to have a groove shape corresponding to the shape of the ball head.

In addition, at this time, in the case of adopting the above-described ball joint method, the seating position prevents rotation in a direction other than the forward rotation direction described above due to a force generated when the head part touches a person's skin while using the razor. During the rotation of the head part 110 in the groove, a neck seating portion where the neck portion of the ball joint 116 is seated may be manufactured to have a shape corresponding to a seating shape when the neck portion is seated. Referring to FIG. 6 (A), since the neck of the ball joint 116 has a rectangular shape, the neck seating portion of the seating groove has a rectangular shape, and referring to FIG. 6 (B), the ball Since the neck portion of the joint 116 has a cylindrical shape, it can be confirmed that the neck portion of the seating groove has a U-shape. At this time, as can be seen through the drawing, both sides of the upper side have a chin that is slightly inwardly folded in common to both the square shape and the U-shape of the neck seating area, so that the neck of the ball head is forcibly caught and It is seated with the feeling of entering, and when it is seated, separation can be prevented.

Although not clearly shown through the drawings, when the neck portion of the ball joint has a predetermined multi-faceted shape (ex. hexagonal shape), the neck seating portion of the seating groove may also have a multi-sided shape capable of accommodating it, of course. . In this way, when the neck and neck seating area of the ball joint are manufactured to have a multi-faceted shape, the head unit rotates in the direction of forming the face of the polyhedron while maintaining the head unit rotated (bent) in the shape of an 'A'. It has the advantage of being able to adjust the angle.

In the same spirit as described above, in order to prevent the angle of the head part from being changed by force when using a razor, as shown in (B) of FIG. And by providing a coupling groove (not shown) at a corresponding position of the neck of the ball joint, it may be fixed through mutual coupling.

[Third Embodiment - Structure of Figs. 7 and 8]

Referring to FIGS. 7 and 8 , according to the third embodiment of the present invention, an example of an angle adjustment type razor using a body portion 120 made of a wire body that is flexible and has bending strength is shown.

At this time, the head part 110 may have a shape similar to that of the razor head of a general razor, but a predetermined fastening structure (this is a screw coupling method (Fig. (see reference numbers 112C and 122C of), slide coupling method, interference fit method, bolting coupling method, male and female screw coupling method, magnetic coupling method, there is no particular limitation on the fastening method).

Instead, the body portion 120 is flexible and has strength, so that when bent or bent with a force greater than or equal to a predetermined amount, the body portion 120 may be manufactured to allow the user to adjust the length and angle desired by the user. To this end, the body portion 120, for example, can be made resistant to corrosion by embedding a wire that withstands up to a certain amount of force and is not reversible inside, and the outer surface is finished with urethane or rubber.

The razor according to the third embodiment described above does not distinguish between directions when bending or bending, and not only simply adjusts the head angle, but also stores the entire razor in a round shape (see (A) in FIG. 8) or a specific part of the body You can also bend it and hang it.

Although the above has been described with reference to the embodiments of the present invention, those skilled in the art will variously modify the present invention within the scope not departing from the spirit and scope of the present invention described in the claims below. And it will be readily understood that it can be changed.
