Description

  The present invention relates to a razor, and more particularly, to a razor in which a single-blade razor blade is slidably attached with an attachment in which a plurality of blade replacement blades are mounted from the back of the sword.

There are two types of commercial razors used in the barber shop: a single-blade razor from the past and a razor to which a two-blade or three-blade replacement blade is detachably attached. A single-blade razor is useful when shaving the contours of the eyebrows, the neckline, etc., because the cutting edge can be visually recognized during face shave. Further, a razor having a plurality of blades detachably attached has an advantage that the time required for face shaving can be shortened because it can be shaved quickly. In addition, there is a “safe razor holder” described in Patent Document 1 as a razor in which a three-blade replacement blade is detachably attached.

  In this way, in the barber shop, it is necessary to use a single-blade razor and a multi-blade razor properly in order to finish face shave in a short time. There was a problem that it was troublesome because it was necessary to bring back the razor, and during that time, the face shaving operation was interrupted. Therefore, the present invention has an object to propose a razor that can efficiently perform face shave work by providing both a single-blade razor function and a multi-blade razor function in one razor.

In order to solve the above problems, a razor according to the present invention is sandwiched between a single-blade blade having a substantially wedge-shaped or flat cross-sectional shape and slidable in the width direction of the blade from the blade back of the blade. And an attachment having a U-shaped cross section, and a replacement blade comprising a plurality of blades detachably mounted on both sides or one side of the attachment.
Further, the blade can be divided into two in the thickness direction, and a replacement single blade can be detachably sandwiched between the two divided blades.
In addition, it is possible to allow the blade to be inserted and removed by using a coupling portion between the base end shaft portion of the blade and the handle portion that supports the blade as a fitting structure.
Furthermore, it is also possible to incorporate a vibration generator in the handle portion that supports the blade.
Still further, the tip end and the base end of the handle portion that supports the blade are divided into two in the middle, and the tip end and the base end are rotatably connected by a connecting shaft, and the base end is connected to the blade edge of the blade. It is also possible to bendable in a plane including the direction.

  As described above, according to the present invention, when the attachment sandwiched between the blades is retracted, it is possible to carefully shave the contour portion with the single blade at the blade tip. Further, when the attachment is advanced, it is possible to shave quickly with a plurality of blades on the side of the attachment. Thus, in the razor of the present invention, although it is a single razor, it is the same as using two razors by switching the attachment forward or backward to improve the work efficiency of face shave. To do. In addition, when the vibration generator is activated, the effect of shaving by vibration is added, so that work efficiency is improved and deep shaving is possible.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show a first embodiment of a razor according to the present invention, and FIG. 1 is a perspective view and a left side view of a state in which an attachment is advanced. 2 is a perspective view and a left side view of the state in which the attachment is retracted from the state of FIG. As shown in these figures, the razor blade 1 has a substantially wedge-shaped cross section and is divided into two pieces from the center, and the front part is a separate cover 3 between which a single blade 2 for replacement is sandwiched. Is done. By removing this cover 3, the replacement single blade 2 can be replaced.

An attachment 4 having a U-shaped cross section is sandwiched between the back surface of the blade 1 and the front surface of the cover 3 from the back side of the blade. The attachment 4 is made of an elastic plastic or is formed by bending a thin metal plate, and the two replacement blades 5 and 6 are detachably mounted on the outer side near the lower end. The attachment 4 is slidably sandwiched in the width direction of the blade 1, and in FIG. 1, the attachment 4 is advanced downward in the figure. In this state, the replacement single blade 2 is attached to the attachment 4. Since it is hidden behind, it is possible to shave with the use of the two blades 5 and 6.

2 shows a state in which the attachment 4 is retracted upward in the figure. In this state, the replacement single blade 2 is exposed from the lower end of the attachment 4, so that the replacement single blade 2 is used. It is possible to shave. The attachment 4 can be moved forward and backward by picking the knob 7 projecting from the top of the upper end of the attachment 4 and sliding it with one touch. Using this razor, when the barber shave the customer's face, when shaving the flat part of the face, the attachment 4 is advanced, and the two-blade blades 5 and 6 are used to efficiently shave the face. .

Here, when shaving the contours of the eyebrows and the neckline, pick the knob 7 and retract the attachment 4 upward, and use the exposed single blade 2 for replacement while accurately observing the cutting edge. The contours of the eyebrows can be shaved. In this way, when the razor of the present invention is used, it is possible to shave while switching the one-blade 2 for replacement and the two-blade replacement blades 5 and 6 with one touch according to the part of the face. The face shaving work can be performed accurately and quickly.

As shown in FIGS. 1 and 2, the razor of the present invention has a motor 9 installed inside a handle 8 that holds the base end of the shaft of the blade 1, and an eccentric weight 10 is provided on the output shaft of the motor 9. It is inserted. When a switch (not shown) is turned on, the motor 9 rotates and vibration is generated by the eccentric weight 10. Vibrations are transmitted to the blade 1, by vibrating the cutting edge of the replacement single blade 2 in the face shaved working two replacement blades 5,6, it is possible to improve the face shaving efficiency. In particular, the output shaft of the motor 9 and are located parallel to the cutting edge of the replacement single blade 2 and two replacement blades 5,6, vibration occurred, one blade 2 and two replacement replacement The vibration rotates in a plane perpendicular to the line segment of the blade edge of the blades 5 and 6, and while acting to promote facial shaving, it is soft against the facial skin and enhances the pleasant feeling of facial shaving. The effect can be expected.

  In addition, the base end part of the axis | shaft of the blade 1 and the connection part of the handle | steering-piece 8 were made into the fitting structure, and the insertion / extraction replacement | exchange of the said blade 1 was enabled. Thereby, the blade 1 or the handle 8 can be removed and replaced with another one. In addition to the blade 1, a T-shaped safety razor can be attached to the handle 8 to shave the face while vibrating.

  FIG. 3 shows a second embodiment of the razor according to the present invention, and is a perspective view showing a state in which the attachment is retracted. Since the structure of the blade 1, the attachment 4, and the motor 9 of this embodiment is the same as that of the first embodiment shown in FIG. 2, the same parts are denoted by the same reference numerals and description thereof is omitted. To do. The feature of this second embodiment is that the handle for holding the blade 1 is folded. That is, the handle distal end portion 11 and the handle proximal end portion 12 are divided into two in the middle, and the distal end portion 11 and the proximal end portion 12 are rotatably connected by the connecting shaft 13. This is for adjusting the opening / closing angle of the base end 12 of the handle when the barber uses a razor to adjust the balance of the razor and to keep the angle of the blade edge at the optimum angle. It is an indispensable structure for a razor.

In the illustrated example, the two-blade replacement blades 5 and 6 are mounted on both surfaces of the attachment 4, but this may be configured such that the two-blade replacement blades are mounted only on one surface. A three-blade replacement blade can also be used. Moreover, although the cross-sectional shape of the blade 1 is an isosceles triangle wedge shape in the illustrated example, even if it is a thin pentagon with the upper portion of the wedge shape being parallel, an attachment can be attached if it is a flat shape. Further, in the illustrated example, the replacement single blade 2 is sandwiched between the blade 1 and the cover 3, but since the blade 1 and the cover 3 are integrated, the blade edge is sharpened to the tip of the blade 1 from the past. Also in the case of the razor, the attachment 4 can be clamped.

  The present invention can be used for a razor having a blade edge sharpened at the tip of the blade, in addition to a razor in which a single blade replacement blade is attached to the blade.
