Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the improvement of a replaceable blade-type barber razor mainly used by hairdressers, and in particular, the replaceable blade has a special shape different from conventional ones. This relates to leather for barbers.

(Prior Art) The present invention is an improvement of a razor using a bend type replaceable blade. A bend-type replaceable blade is a replaceable blade shown in Figure 8, in which a bent part is formed at an angle near the lower edge of the replaceable blade, and the end of the bent part is ground vertically to form a blade edge. It is a spare blade with a If such a replaceable blade is mounted vertically in a holder as in the past, the bent portion and the blade edge formed thereon will be slanted, making it difficult to shave. Therefore, it is necessary to attach the spare blade to the holder diagonally so that the bent part is vertical.

Conventional razors in which the spare blade is mounted diagonally in the holder are slanted so that the blade edge of the razor moves away from the center of the holder.

(Problems to be Solved by the Invention) Conventional razors in which the spare blade is attached to the holder at an angle have the above-mentioned configuration, and the edge of the blade is away from the center of the holder. The disadvantage is that the stress received from the beard creates a large moment, making it difficult to use.

The present invention aims to eliminate these drawbacks of conventional products.

(Means for Solving the Problems) The present invention provides a replaceable blade type barber razor in which a replaceable blade 3 is removably held between a main body 4 and a side plate 5. , a bent part is formed along the lower edge to be inclined toward one surface of the replaceable blade, and the end of the bent part is ground vertically to perform vertical grinding offset from the one surface of the replaceable blade. Face 8
By forming this, the lower end of the vertical grinding surface 8 becomes a blade edge 6, and when this replaceable blade 3 is attached to the holder 1 formed by the main body 4 and the side plate 5, the blade edge 6 is the main body 4 and side plate 5 of the holder 1
(Example) Next, according to the present invention Examples will be described according to the drawings.

In this embodiment, a plate-shaped adapter 2 is used to tilt the replaceable blade 3 with respect to the holder 1. 3 are inserted and aligned along the entire surface, and they are clamped between the main body 4 and the side plate 5.

The adapter 2 is formed into a substantially rectangular plate shape,
Two locking protrusions 10 are provided near both ends of the upper edge.
10 are integrally provided, and the upper halves of these locking protrusions 10, 10 are shaped to protrude on both sides. In addition, the adapter 2 is tapered so that it gradually becomes thinner from the upper edge to the lower edge 16, and the convex parts 12, 12 of the replaceable blade slide in the longitudinal direction on both sides of the adapter 2. Groove 1
4 and 14 are provided.

As shown in FIG. 8, the replaceable blade 3 has a bent part that is bent along the lower edge toward one surface of the replaceable blade in the vicinity of the lower edge, and the end of the bent part The vertical grinding surface 8 is offset from one surface of the blade by grinding the part vertically, i.e. parallel to the center line 7.
By forming this, a blade edge 6 is formed at the lower edge of the vertical grinding surface 8. Furthermore, protrusions 12, 12 are formed near both ends of the upper part of the replaceable blade. Reference numeral 17 is a hollow hole.

The holder 1 is formed from a main body 4 and a side plate 5,
The main body 4 is integrally formed with an elongated finger rest 9 on which a finger is placed during use, and a plate-like portion for holding a replaceable blade connected to the front end thereof. The side plate 5 is formed in substantially the same shape as the plate-shaped portion of the main body 4 for holding the replaceable blade, and functions to hold the replaceable blade 3 in cooperation with the main body 4. Two locking recesses 11, 11 are provided on the upper inner surfaces of the main body 4 and the side plate 5, respectively.
These locking recesses 11, 11 work together with the locking protrusions 10, 10 of the replaceable blade to prevent the adapter 2 incorporated into the holder from moving in the front-rear direction. Further, a long groove 1 is provided in the longitudinal direction below the locking recesses 11, 11 of the main body 4 and the side plate 5.
3 and 13 are provided. This long groove 13, 13
serves to accommodate the slightly wider upper edge portion of the adapter 2.

The inner surfaces of the main body 4 and the side plates 5 are formed to be inclined so as to approach each other as they go downward.
Since the adapter 2 also has an inclined side surface that becomes thinner as it goes downward, the replaceable blade 3 along one side surface 15 is inclined by the same amount as the inner surface of the main body 4 or the side plate 5. It will be installed on 1.

Reference numeral 18 denotes a sliding pressure plate, which is attached to cover the upper side of the holder 1 and is attached to the adapter 2.
And it acts to press and clamp the replaceable blade 3. This sliding pressure contact plate 18 can be slid back and forth on the holder, and the pressure contact state can be released by sliding it in either direction.

FIG. 1 is a sectional view showing the state in which the replaceable blade 3 is attached to the holder 1, showing the plate-shaped portion of the main body 4 and the side plate 5.
Adapter 2 is inserted between them. As mentioned above, the locking protrusion 1 of the adapter
0 and 10 are locked in the locking recesses 11 and 11 of the holder to prevent the adapter 2 from moving within the holder 1. In order to maintain the overlapping state of the main body 4 and side plate 5, a cross section U is formed on the upper part of them.
A letter-shaped sliding pressure contact plate 18 is attached so as to be slidable in the front-rear direction. Although FIG. 1 shows a state in which the sliding pressure contact plate 18 is strongly pressed against the main body 4 and the side plate 5, and the replaceable blade 3 is clamped and fixed in the use state, it is not possible to slide the sliding pressure contact plate 18. The pressed state can be released by

The replaceable blade 3 is inserted and attached from the front side of the holder when the sliding pressure contact plate 18 is released from the pressure contact state. During insertion, the recesses 12, 12 of the replaceable blade will pass through one sliding groove 14 of the adapter.
In this embodiment, the replacement blade 3 is inserted into the main body 4.
However, it is also possible to invert the replaceable blade 3 and insert the replaceable blade so as to contact the inner surface of the side plate 5. Spare blade 3 like this
The reason why we made it possible to flip the blade over and put it on again is because after using the blade for a while, the blade edge of the blade will curl in one direction and lose its sharpness. This is because the edge of the blade comes into contact with the hair and beard and the sharpness is restored again.

The side plate of the adapter 2 is inclined so that it becomes thinner as it goes downward, and the inner surface of the holder 1 is also inclined so that it becomes narrower as it goes downward.
The replaceable blade 3 inserted into the holder is mounted in an inclined state corresponding to the inclination of the side surface of the adapter and the inner surface of the holder, and is slid on the sliding pressure contact plate 18 and fixed by being clamped. As a result of the replaceable blade 3 being clamped at an angle, the originally bent portion becomes almost vertical, and the blade edge 6 is located on an extension between the main body 4 and the side plate 5 of the holder 1.

The explanation of the embodiment is as above, but the configuration in which the replaceable blade 3 is attached to the holder at an angle is not limited to the one using the adapter 2 as in this embodiment. Any configuration is acceptable as long as it can be mounted obliquely to the vertical line of the holder so that the bent part of the replaceable blade approaches vertically; for example, the adapter 2 may be integrated with the main body 4 or the side plate 5. good.

As means for clamping and fixing the replaceable blade 3 with the main body 4 and side plate 5 of the holder 1 in a press-contact state, in addition to the method shown in the embodiment, there is also an attachment method of tightening with a pin or nut.

(Effects of the Invention) The present invention has the above configuration, and the replaceable blade of the present invention has a special shape as described above.

Therefore, in the replaceable blade 3 of the present invention, the center line 7 of the replaceable blade 3 is aligned with the main body 4 of the holder 1 and the side plate 5 as in the conventional case.
If the replaceable blade 3 is attached so as to coincide with the holder 2, the downwardly bent portion of the replaceable blade 3 will be greatly inclined with respect to the holder 2. When the disposable blade 3 of the present invention is used for shaving, etc., it is used so that the downwardly curved part of the blade is bent toward the outside and hits the face. If this occurs, the condition will be the same as applying a conventional flat blade to the skin in an extremely reclined position, and in this condition you will not be able to get a close shave. For this reason, when using the replaceable blade 3 of the present invention as in the past, when the center line 7 of the replaceable blade 3 is aligned with the space between the main body 4 and the side plate 5, the holder 1 itself is raised further toward the skin. must be used. However, shaving in this way requires twisting one's hands, which quickly becomes tiring.

In the present invention, as described above, the replaceable blade 3 is attached to the holder 1.
As a result, the downward bent portion of the replaceable blade 3 can obtain the same effect as if it were placed in front. Therefore, the user can work without having to twist his or her hands like in the past, so the user does not get tired even when working for long hours.

Moreover, the blade edge 6 is connected to the main body 4 of the holder 1 and the side plate 5.
Holder 1
Since no moment about the longitudinal axis is generated, or even if it is generated, the moment is extremely small, the handle 9 can be comfortably held while working.

Further, in the present invention, a bent portion is formed along the lower edge, and the blade edge 6 is formed by vertically grinding the end of this bent portion. Conventionally, it was necessary to grind and polish both sides of the blade edge of barber-required razor blades, but with the present invention, only one side needs to be ground and polished, so the process for forming the blade edge is simple, and the blade edge is easy to use. can reduce costs.
