[Technical field to which the device belongs]

 The present invention relates to an improvement of a replaceable blade type barber laser.

[0002]

[Prior art]

 A razor used by a barber to shave at a barber shop is generally a so-called western razor with a single blade, but this western razor requires double-edged skill to sharpen the cutting edge. In addition, it takes time to sharpen the blade of the razor before and after shaving. A barber-use laser is troublesome because it requires a lot of care for daily care, and a razor with a thin blade and a large inclination to the skin can be shaved without feeling pain. . On the other hand, a replaceable blade type laser has been developed in which the blade of the razor can be replaced so as to easily obtain a cutting edge with good sharpness without the need to sharpen the cutting edge before shaving.

This spare-blade type laser-1 forms a holding side plate 3 having a substantially wedge-shaped cross section, which is continuous with a handle portion 2 which is formed in a long shape and is provided at a rear end thereof. A movable side plate 4 formed symmetrically to the side plate and having substantially the same cross-sectional shape is hingedly connected to the sandwiching side plate 3 so as to face each other, and a spare blade 5 is sandwiched between the sandwiching side plate and the movable side plate. A wedge body 7 is housed in an accommodating chamber 6 formed by forming notches in the rear upper portions of the sandwiching side plate 3 and the movable side plate 4 so that the wedge body 7 can be freely inserted and removed. The movable side plate is rotatably engaged in recesses 3b, 4b provided on one side of the accommodation portion of the movable side plate. In addition, the recessed grooves 8a and 8b are provided at the same positions in front of the inner surfaces of the both side plates with different lengths, and the front boss portion 8c and the rear boss portion 8d are provided at different positions into the recessed grooves 8a and 8b, respectively. The bosses 8c and 8d are linearly aligned with each other, and the long screw 9 is screwed from the front side. Further, an insertion rod 4c provided at a rear portion of the movable side plate 4 is inserted into a small hole 2a provided at a front end of the handle portion 2 to hingely connect both side plates 3 and 4.

[0004]

[Problems to be Solved by the Invention] A wedge body 7 is press-fitted into a storage chamber 6 provided in the upper rear portion of the sandwiching side plate 3 and the movable side plate 4 to push the sandwiching side plate and the movable side plate to the left and right to sandwich them. The lower part of the side plate 3 and the movable side plate 4 is narrowed to sandwich the spare blade 5. Therefore, as shown in FIGS. 1 and 2, since both side plates 3 and 4 are thick and the vertical width is long, the weight of the laser-1 is heavy and it is used for a long time. My wrist was tired easily. Further, when a step 10 is formed between the lower ends of the side plates 3 and 4 and the spare blade 5, and the spare blade is slightly exposed from the lower portions of both side plates, when the laser is inclined, Since the lower end side surface of the side plate is in contact with the surface of the skin S and the laser-1 cannot be tilted beyond the angle R, there is a problem that it is difficult to shave deeply and difficult to use. According to the present invention, curved portions are provided on the outer surfaces of the sandwiching side plate and the movable side plate to reduce the wall thickness, and the sandwiching side plate and the movable side plate are formed to have a shorter vertical width than before, and the spare blade is largely exposed and attached. -The purpose is to allow a large inclination angle.

[0005]

[Means for Solving the Problems]

 As described above, according to the present invention, in a barber laser in which a sandwiching side plate having a handle portion at the rear portion and a movable side plate are hingedly connected, a peak portion is formed on each of the sandwiching side plate and the movable side plate. By providing curved portions on the outer surfaces of the sandwiching side plate and the movable side plate respectively, the step difference between the replacement blade sandwiched at the lower ends of the sandwiching side plate and the movable side plate and the lower ends of the sandwiching side plate and the movable side plate is reduced. And Further, according to the present invention, in the front part of the handle part provided at the rear part, the upper part of the sandwiching side plate which is formed in a half-divided shape is formed to be thick, and a peak part which also serves as a reinforcing part is provided. By making it short and providing a curved portion on the outer surface, the thickness is cut off to form a thin wall, and a front boss portion is provided in front of the half-groove provided on the inner surface of the sandwiching side plate and at the rear end. A locking hole is formed, the upper part of the movable side plate is thickly formed to provide a ridge part that doubles as a reinforcing part, and the vertical width of the movable side plate is formed to be short, and a curved part is provided on the outer surface to reduce the thickness. It is formed into a thin wall by dropping it, and a rear boss is provided in front of the half groove provided on the inner surface of the movable side plate so as to be positioned on the rear side of the front boss. And the rear boss are screwed to engage the projections provided at the rear ends of the half-grooves with the locking holes and are hingedly connected. A wedge is provided inside the opening by attaching a replacement blade between the plate and the movable side plate, and operating the operating piece housed in the opening provided on the upper surface of the ridge of the sandwiching side plate and the movable side plate in the front-back direction. It is characterized in that the replacement blade is detachably held by a wedge action between a sliding groove and a guide piece provided at a lower portion of the operating piece. Further, according to the present invention, the spare blade mounted between the sandwiching side plate and the movable side plate is made to closely sandwich the upper both sides of the spare blade between the both side plates, and the spare blade is largely exposed from the lower ends of the sandwiching side plate and the movable side plate. It is characterized by mounting. In this way, the vertical width of the sandwiching side plate and the movable side plate is shortened, and the curved parts are provided on the outer surface of each to scrape off the meat, which makes it lighter in weight and easy to handle, and also reduces the step between the blade and the replacement blade. Since the blade is mounted so as to be exposed to a large extent, the razor can be shaved by inclining the laser greatly.

[Embodiment of device]

 An embodiment of the present invention will be described with reference to FIGS. 5 to 11. This barber razor 11 is entirely elongated and has a gripping side formed in a half-divided shape at the tip of a handle portion 13 provided at the rear. The plate 14 is integrally provided. A movable side plate 25, whose cross-sectional shape is formed symmetrically with the holding side plate 14, is hinged to the inside of the holding side plate 14 so as to be pivotable. An inner surface of the sandwiching side plate 14 is provided with a half-groove 15 in the middle in the longitudinal direction, a front boss portion 16 is provided substantially in the half-groove 15, and the rear end of the half-groove 15 is continuously locked. A hole 17 is formed. The upper portion of the sandwiching side plate 14 is formed by increasing the strength and decreasing the thickness of the ridge portion 35 which also serves as a reinforcing portion so as to be thinner than the conventional one. A rectangular half-divided opening 18a is formed behind the ridge portion 35, and a half-divided sliding groove 19a is formed on the lower inner wall surface of the half-divided opening 18a. .

The lower side of the half groove 15 of the sandwiching side plate 14 is formed with a locking step portion 20 for locking the back portion of the spare blade 5, and the center portion of the locking step portion has a backlash of the spare blade. A curved portion 21 is provided to prevent sticking. On the inner surface of the movable side plate 25 facing the holding side plate 14, a half groove portion 26 is also formed at a position facing the half groove 15 of the holding side plate 14, and the inner surface of the holding side plate 14 and the movable side plate 14 are also formed. When the inner surfaces are aligned, the half groove 15 and the half groove portion 26 form a cylindrical space. The upper portion of the movable side plate is formed by increasing the strength and decreasing the thickness of the ridge portion 36 which also serves as a reinforcing portion so as to be thinner than the conventional one. A rectangular half-split opening 18a is formed behind the ridge portion 36, and a half-split sliding groove 19a is also formed on the lower inner wall surface of the half-split opening 18a. . The openings 18a, 18a are aligned to form a rectangular opening 18, and the sliding grooves 19a, 19a are aligned under the opening 18 to form a wedge sliding groove 19. There is. The wedge sliding groove 19 is formed in a taper shape such that the front side of the opening 18 is narrow and the rear side is wide (FIG. 9).

A rear boss portion 27 is provided in the half groove portion 26 of the movable side plate 25 so as to be positioned behind the front boss portion 16 of the holding side plate 14, and the half groove portion 26 of the movable side plate 25 is provided. The protrusion 28 provided at the rear end is engaged with the locking hole 17. Then, the long screw 29 is inserted from the tip of the cylindrical space and screwed integrally with the front boss portion 16 and the rear boss portion 27 so that the movable side plate 25 can be slightly rotated with respect to the holding side plate 14. It is hinged.

Both the outer surfaces of the sandwiching side plate 14 and the movable side plate 25 are curved so that thick portions are cut off to form curved portions 14a and 25a, respectively, which are shorter than the conventional vertical widths of the sandwiching side plate and the movable side plate. Therefore, the spare blade 5 is mounted so as to be largely exposed. The steps between the spare blade 5 and the lower ends of the sandwiching side plate 14 and the movable side plate 25 are reduced (FIG. 7), so that when shaving a beard, the barber laser 11 is largely inclined (FIG. 6). In addition, we are trying to reduce the weight of the barber laser. The sandwiching side plate 14 and the movable side plate 25 are provided on the inner surfaces thereof with contact surfaces 14b and 25b which are formed to be flat, and the upper end of the contact surface 14b is continuous with the locking step portion 20. In addition, the upper portions of the curved portions 14a and 25a are curved outward and the upper end is formed to have a thick wall, and as shown in FIG. 5, peak portions 35 and 36 are provided to increase the strength of the sandwiching side plate 14 and the movable side plate 25. I am maintaining. This ridge portion is also formed to have a smaller thickness than the conventional laser. The barber-laser 11 is capable of deeply shaving and is easy to use because it can greatly incline the inclination angle r of the blade with respect to the skin s when shaving a beard. It is possible (Fig. 6).

Reference numeral 30 denotes an operating piece housed in the opening 18, which is slidably housed in the opening 18 provided on the upper surface when the sandwiching side plate 14 and the movable side plate 25 are hingedly coupled (see FIG. 5). The taper-shaped inner piece 32 provided in the lower portion of the operating piece 30 via the connecting portion 30a provided in the lower portion is slidably accommodated in the wedge sliding groove 19. That is, when the actuating piece 30 is placed on the front side, the upper parts of the sandwiching side plate 14 and the movable side plate 25 can be spread to the left and right, and thereby the lower parts of the sandwiching side plate 14 and the movable side plate 25 can be narrowed.

When this laser 11 is used, when the operating piece 30 shown in FIG. 10 is moved forward, the taper-shaped guide piece 32 advances in the wedge sliding groove 19. The opening 18 is pushed to the left and right, and the movable side plate 25 is hinged about the front and rear bosses 8c and 8d and the protrusion 28 to narrow the lower end of the movable side plate 25. Further, after the back portion of the spare blade 5 inserted from below between the holding side plate 14 and the movable side plate 25 is brought into contact with the locking step portion 20, the guide piece 32 and the wedge sliding groove 19 are formed. Due to the wedge action, the replaceable blade 5 can be firmly clamped between the clamping side plate 14 and the movable side plate 25. In this case, since the sandwiching side plate 14 and the movable side plate 25 are formed shorter than those of the conventional one, the spare blade 5 is mounted so as to be largely exposed (FIG. 7).

When replacing the replaceable blade 9, when the actuating piece 30 is moved backward, the guide piece 32 of the actuating piece retracts in the wedge sliding groove 19, and the opening 18 by the actuating piece 30 is moved in the left-right direction. Since the force of pushing out is canceled and the space between the upper part of the movable side plate 25 and the upper part of the sandwiching side plate 14 is narrowed, both contact surfaces 14b and 25b provided on the inner surfaces of the lower parts of the sandwiching side plate 14 and the movable side plate 25 are reduced. The blade 5 can be opened to take out the spare blade 5, and then a new spare blade can be inserted to easily replace the spare blade.

When shaving a beard using the laser according to the present invention, as shown in FIG. 6, the inclination angle with respect to the surface s of the skin is larger than the inclination angle R of the conventional laser. As shown by r, the inclination can be made even greater, so even a beard with a soft and hard contact with the skin can be shaved smoothly without causing pain. Also, in the case of a dark beard, many customers are not satisfied unless they are back-shaving, and since the back-shaving easily causes bleeding, replace the replacement blade 5 in case of bleeding due to shaving in order to prevent blood infection. You can do it. Of course, when shaving does not cause bleeding, the spare blade can be washed with water and used until the sharpness deteriorates.

[0014]

[Effect of device]

 According to the present invention, since the curved portions are provided on the outer surfaces of the sandwiching side plate and the movable side plate, the wall thickness can be reduced to reduce the step difference between the blade and the spare blade, and to reduce the weight of the barber laser. Because it is easy to handle, the cost is low, and even if you use it for a long time, there is little hand fatigue. Also, by reducing the wall thickness of the sandwiching side plate and the movable side plate to reduce the step between the blade and the blade, the angle of inclination of the blade edge when shaving a beard can be increased, and even a hard beard can be smooth. It has the advantage of being shaveable and easy to use. In addition, in the case of a customer who is not satisfied unless he / she shaves a dark beard, if he / she bleeds and has bleeding, he / she can prevent the illness caused by blood infection by replacing the blade of the barber laser. You can reassure customers because you can.
