Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a structure in which a scraping blade is movable along the side surface of a main body case, and a scraping blade is protruded from the main body case.
Regarding electric razors that can be stored freely.

(Prior Art) There are various types of electric razors, but electric razors with sharpening blades are generally preferred for their convenience.

The shaving blade is usually used to align sideburns or, for example, to cut relatively long beards that grow on the chin as a prelude to continuous shaving.

In the former case, it is desirable to have a structure that prevents the main blade from getting in the way and accidentally cutting hair when using the shaving blade.

In the latter case, it is preferable that the beard be configured so that the beard does not get in the way during continuous cutting, in which long beards are first cut with the beard and then shortened with the main blade.

By the way, as shown in FIG. 10B, for example, as shown in FIG. In some cases, as shown in FIG. 10A, the scraping blade 61 is housed below the main blade 62, and the scraping blade 61 rotates and protrudes below the main blade 62. .

However, in the former case, the scraping blade 64 is always protruding to the side, which makes it look unsightly, and the scraping blade 64 is easily damaged when it hits another object or falls. Moreover, the blade at the tip of the scraping blade 64 after moving is the main blade 6.
Because it is extremely close to 2, the sharp edge 6
4, there is a risk of hair being cut with the main blade 62, and although the latter problem solves the problem of appearance and damage, the posture of the main body case 63, that is, the sharpening blade 61 When used by changing the application angle, although the scraping blade 61 is laterally separated from the main body case 63 in the protruding state, its position is considerably lower than the main blade 62, so when the scraping blade 61 is used, the main blade 61 ends up being The problem remains that the blade 62 cuts hair, making it difficult to use.

Therefore, in order to solve these problems, we
As shown in No. 56-57477, it has been proposed that the scraping blade is movable up and down and rotates and protrudes in conjunction with the upward movement.

(Problem to be Solved by the Invention) However, in this electric razor, the shaving blade rotates and protrudes above the top of the main blade, so there is no chance of accidentally cutting hair when using the shaving blade. However, there is a problem in that when a long beard is first cut with a shaving blade, and then the main blade is used to cut it short, the shaving blade gets in the way, making continuous sledding impossible.

In addition, since the scraping blade is supported on a cantilever by being moved to a position above the top of the main blade, there is a difficulty in supporting the scraping blade when it projects upward, so special measures must be taken to the support structure to ensure firm support. In short,
In addition, with this device, the scraping blade sometimes wobbles during use, making it difficult to use, and the supporting portion is easily damaged when the scraping blade hits another object.

The present invention has been proposed in view of the above points, and its purpose is to enable the scraping blade to move up and down, and when moved upward, the stored scraping blade will protrude outside. In this type of electric razor, in addition to not cutting hair with the main blade when using the shaving blade, continuous shaving can be easily performed using the shaving blade and the main blade, and the shaving blade is To provide an electric razor which can be firmly supported, is easy to use without wobbling of the scraping blade, and has little damage to the scraping blade even if it hits other objects.

(Means for Solving the Problems) In the present invention, a main blade is provided in the upper part of the main body case, and the scraping blade is made vertically movable along the side surface of the main body case, and the scraping blade protrudes in conjunction with the movement. In the electric razor that can be freely stored, the shaving blade is stored along the main body case at a position away from the main blade downward, and the shaving blade is moved upward so as to be below the top of the main blade. The above object is achieved by configuring the blade to be close to the main blade at a position and to project the cutting edge to the side away from the main blade.

(Function) When the electric razor of the present invention is not in use, it is housed along the main body case at a position away from the main blade, and when the razor blade is slid upward from this state, the main blade is When the blades are close to each other and at a position below the main blade, the cutting edge protrudes to the side away from the main blade, and when in use, the scraping blade is located below the main blade and close to the main blade. By doing so, the amount of upward protrusion of the scraping blade is reduced and the support is strengthened, and continuous scraping using the scraping blade and the main blade can be easily performed, and the cutting edge of the scraping blade is separated from the main blade. By protruding to the side, the main blade does not get in the way when only the cutting blade is used, so that hair will not be accidentally cut.

Embodiment 1 FIGS. 1 to 5 show a first embodiment of the present invention. First, in FIGS. 1 to 3, a base 3 holding a motor 2 is inside a main body case 1. An eccentric shaft 8 of an eccentric cam 7 disposed and attached to the shaft of the motor 2 is fitted into a through hole 6 formed in an arm portion 5 of a reciprocating resin driver 4.

Further, a waterproof rubber 18 is attached between the switch frame 16 and the main body case 1 to waterproof the opening 17 of the main body case 1. Further, as shown in FIG. 3, a protrusion 19 is formed on the inside of the switch handle 14, and when the switch handle 14 is operated, the switch spring 20 on the base 3 is pressed, and the contact 21 and the switch spring 20 are brought into contact with each other. It constitutes an electric circuit and drives the motor 2.

As shown in FIG. 2, a pair of opposing protruding pieces 22 are disposed at the upper part of the switch frame 16, and a sharpening blade case 23 is disposed between these protruding pieces 22.
is slidably attached. Below the main blade 24 consisting of the inner cutter 11 and the outer cutter 13, inside the cutter blade case 23, a cutter blade housing 25 is formed as shown in FIG. The rear portion of the blade 26 is rotatably supported. Further, a lever 27 is provided on one side of the scraping blade 26 for rotating and protruding it (see Fig. 2), and this lever 27 is provided with an elongated hole 27a and a boss attached to the scraping blade 26. 26a is engaged.

The switch handle 14 is located below the sharpening blade 26.
A click member 28 is disposed behind the switch handle 14 and extends to a position overlapping the click member 15 of the switch handle 14. In addition, as shown in FIG.
On one side, an operating handle portion 29 of the scraping blade case 23 extends to a side surface of the main body case 1.

The lower part of the lever 27 and the sharp blade case 2
A return spring 31 for the scraping blade 26 is provided between the substantially U-shaped rib 30 formed at the lower part of the blade 3, and the spring pressure of the return spring 31 prevents rattling of the scraping blade 26 when it is stored. It is prevented. Further, a protrusion 27b is provided approximately at the center of the lever 27, as shown in FIG. 5, which will be described later, and is designed to function as a stopper for the lever 27 when the scraping blade 26 rotates and protrudes.

Furthermore, a drive rod 32 is provided behind the scuffing blade storage portion 25 for driving the scuffing blade 26 by engaging the scuffing blade 26 and the driver 4 when the scuffing blade 26 rotates and protrudes.

Next, this operation will be explained. Now, when the switch handle 14 is stopped from the stored state of the scraping blade 26 shown in FIGS.
is pressed and brought into contact with the contact point 21, and the motor 2 is driven. When the motor 2 rotates, the driver 4 reciprocates via the eccentric cam 7, the inner cutter 11 vibrates, and only the main cutter 24 operates in cooperation with the outer cutter 13.

Next, when the operating handle portion 29 is stopped,
Kiwazori blade case 2 containing the Kiwazori blade 26
3 is stationary along the side surface of the main body case 1, and as shown in FIG.
6 rotates and protrudes.

The rotating and protruding state of the scraping blade 26 will be explained in more detail based on FIG. 5. First, in the position shown in FIG. 5, the scraping blade 26 is in the retracted state. Next, when the operating handle portion 29 is moved upward, the protrusion 27b of the lever 27 is locked to the blade mount 33 (FIG. 2B).
If the operation handle portion 29 is further moved upward, the scraping blade case 23 will be raised, but since the lever 27 is in the locked state, the protruding boss 26a of the scraping blade 26, which is engaged with the elongated hole 27a of the lever 27, will be rotated. The scraping blade 26 starts rotating as a moving axis (FIG. 3C).
Thereafter, by further moving it upward, the scraping blade 26 rotates and comes into a state of protruding laterally (FIG. 2D).

In this state, the scraping blade 26 is the main blade 2.
4, and the rear part of the scraping blade 26 is pivoted and rotates to protrude, so the amount of horizontal protrusion is also sufficient, and the scraping blade 26 has a sufficient horizontal protrusion.
Because the cutting edge at the tip of No. 6 is far from the main blade 24,
There is no risk of accidentally cutting the hair with the main blade 24 during shaving.

Furthermore, in the state shown in FIG. The scraping blade 26 slides back and forth and becomes ready for use. When using it, there is no risk of cutting hair as mentioned above, and
Since the scraping blade 26 protrudes below the main blade 24, continuous scraping can be easily performed. Further, the stroke of vertical movement of the scraping blade 26 is small, the scraping blade 26 can be firmly supported, and the scraping blade 26 does not wobble, making it easy to use.

Note that when the scraping blade 26 is not in use, when the operating handle portion 29 is lowered, the scraping blade 26 rotates and returns to its original position due to the lever 27 and the spring pressure of the return spring 31 provided in the scraping blade case 23. The cutting blade 2 is stored in the storage part 25.
6 is stored along the main body case at a position downwardly away from the main blade 24.

According to this embodiment, since the click member 15 of the switch handle 14 and the click member 28 of the scraping blade 26 are provided in an overlapping position, there is an advantage that less space is required for the click member.

According to this embodiment, in addition to the advantages of the first embodiment, the movement and rotational protrusion of the scraping blade 55 are performed by the rack 52 and pinion 56, so that the rotational protrusion operation can be performed smoothly, and the rack 52 and By changing the degree of engagement of the pinion 56, the rotation angle of the scraping blade 55 can be freely selected, which has the advantage of being easy to use.

(Effects of the Invention) As described above, according to the present invention, the main blade is provided in the upper part of the main body case, and the scraping blade is made vertically movable along the side surface of the main body case, and the scraping blade is moved in conjunction with the movement. In the electric razor, the shaving blade is stored along the main body case at a position downwardly away from the main blade, and the shaving blade is moved upward to close the top part of the main blade. Since it is configured to be closer to the main blade at a lower position and protrude laterally away from the cutting edge, the following effects can be achieved.

(a) As mentioned above, the scraping blade moves from the inside of the main case to a position close to the main blade located at the end of the main case, and the cutting edge of the scraping blade moves to the side so that it is sufficiently far away from the main blade. Since the main blade protrudes from the main blade, it does not get in the way when using the razor blade, and there is no risk of accidentally cutting the hair.

(b) Also, since the shaving blade is close to the main blade and protrudes below the top of the main blade, long beards are first cut with the shaving blade, and then finished short with the main blade. Even when doing continuous sledding, the scraping blade does not get in the way, making it easy to do continuous sledding.

(c) Also, since the configuration described in (a) above is adopted, the stroke of the vertical movement of the scraping blade is smaller compared to the case where the scraping blade rotates and protrudes at a position above the main blade. The support is firm and the scraping blade does not wobble, making it easy to use, and the supporting part of the scraping blade is less likely to be damaged even if it hits another object.
