Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an electric razor of a type in which a scraping blade is movable along the side surface of a main body case, and the scraping blade can be protruded and stored in conjunction with the movement. .

(Prior art) In general, the closer the Kirazori blade is to the edge of the main case when used, or the closer it is to the position that protrudes from the end, the less the main case will get in the way, and the storage position when not in use is The further inward from the edge of the case, the less likely it will be affected by a shock, such as when dropped, and damage can be prevented.

However, in the conventional electric razor having a scraping blade, as shown in FIG. Some are configured to protrude downward.

In addition, as shown in Figure 6 B, when using the scratching blade 6
4 is located near the end of the main body case 63.

However, in the former electric razor,
Since the scraping blade 61 is located below the main body case 63 when protruding, that is, it is located considerably inward from the end of the main body case 63, it is possible to prevent the scraping blade from being damaged if it falls when not in use. When the blade 61 is in use, the edge of the main body case 63 gets in the way, making it difficult to use.

In addition, in the latter case, when using the scratch blade 6
4 can be brought close to the main blade 62, (a)
Although there is no drawback as shown in the figure, since the scraping blade 64 is configured to always protrude to the outside, there is a risk of damaging the blade portion.

Therefore, as shown in Japanese Patent Application Laid-Open No. 56-57477, there is a device in which the scraping blade is made to be slidable and is projected above the main blade when in use. Therefore, this electric razor does not have the drawbacks of the electric razors shown in FIGS. 6A and 6B.

(Problem to be Solved by the Invention) However, the scuffing blade in JP-A No. 56-57477 protrudes close to the main blade, so while it is easy to use, when cutting sideburns with the scuffing blade, it is difficult to cut the hair around the sideburns. If the hair is long and extends to the sideburns, or if the hair has been permed and the perm loosens, the hairstyle will swell, and the main blade will get caught in the hair and cut it. There is a risk.

For this reason, it is desirable to adopt a structure in which the drive of the main blade is stopped using a changeover switch, for example, when using a scraping blade, but such a structure would complicate the internal structure and complicate assembly. This results in high costs, which is not preferable.

The present invention has been proposed in view of the above, and its purpose is to enable the scraping blade to freely slide from the stored state to a position close to the main blade, and to provide a mechanism in which the scraping blade is slidable in conjunction with the sliding movement. To provide a protruding type electric razor which prevents hair from getting caught by a simple means and is easy to use.

(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 movable along the side surface of the main body case, and the scraping blade is protruded and stored in conjunction with the movement. In the electric razor that is flexible, the shaving blade has a blade at the tip, the rear end is rotatably supported, and is housed along the main body case at a position downwardly away from the main blade, and the A hair guard protrusion is provided that protrudes to the side in a position close to the main blade and protrudes from the upper surface of the crease blade between the main blade and the crease blade, and this hair guard protrusion is provided with the rotational support. The above-mentioned object is achieved by having a structure in which the protrusion is not rotatable, moves up and down together with the scraping blade, and has a forward-sloping slope on the upper part.

(Function) In the present invention, when the scraping blade is not in use, the scraping blade is stored in the scraping blade case, and when the scraping blade case is slid from this state toward the end of the main body case, the scraping blade moves laterally. In this case, a hair guard projection is provided between the shaving blade and the main blade that protrudes from the top surface of the shaving blade, and this projection prevents hair from getting caught in the main blade. That's what I do.

Further, since the hair guard protrusion covers the rotating part of the shaving blade and has a sloped surface that slopes downward, beard debris can easily fall off due to the sloped surface, making it difficult for beard debris to enter.

Furthermore, during the cutting process, the hair that grows along the face is pressed down toward the face by the slanted surface, making it difficult for the hair to move toward the main blade.

(Embodiment) FIGS. 1 to 5 show an embodiment of the present invention.

In this embodiment, a hair guard protrusion is provided between the main blade and the shaving blade in an electric razor of the type in which the shaving blade is moved upward and projected as the switch handle is moved upward.

That is, first of all, in FIGS. 1 to 3, a base 3 holding a motor 2 is disposed inside the main body case 1, and an eccentric shaft 8 of an eccentric cam 7 attached to the shaft of the motor 2, It fits into a through hole 6 formed in an arm portion 5 of a reciprocating resin drive element 4. Further, the driver 4 includes an engaging protrusion 9,
It extends upward through the waterproof rubber 10 and is connected to the inner cutter 11 forming the inner cutter block. On the other hand, 12 is an outer cutter frame, and the outer cutter 13 is attached in an arch shape, and the outer cutter frame 12 is detachable from the main body case 1. A main blade 24 consisting of a blade 13 and an inner blade 11 is provided.

In addition, on the front of the main body case 1, there is a
A switch handle 14 for performing an OFF operation and a click member 15 for obtaining a click feeling of the switch are slidably attached to a switch frame 16 fixed to the main body case 1. Furthermore, 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 to this Kiwazori blade case 2.
The upper part of 3 is a protrusion 23a for hair guard. Further, below the main blade 24 consisting of the inner cutter 11 and the outer cutter 13, a scuffing blade storage section 25 is formed inside the scuffing blade case 23 as shown in FIG. A scraping blade 26 having a blade at the tip thereof is rotatably supported at its rear end, and the upper surface of the scraping blade 26 has an inclined surface consisting of a front-down tapered portion protruding from the upper surface for a hair guard, and A protrusion 23a is provided to cover the above-mentioned rotating portion of the scraping blade 26. Further, a lever 27 is provided on one side of the scraping blade 26 to allow the scraping blade 26 to rotate and protrude laterally (see Fig. 2), and this lever 27 is provided with a long hole 27a, which is attached to the scraping blade 26a. boss 26a
is engaged.

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

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. , 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, to function as a stopper for the lever 27 when the scraping blade 26 is rotated and protruded.

Furthermore, behind the scuffing blade storage part 25, when the scuffing blade 26 rotates and protrudes, this scuffing blade 29 is provided.
A drive rod 32 is provided for driving the scraping blade 26 by engaging the drive element 4 with the drive element 4 .

Next, this operation will be explained. Now, when the switch handle 14 is moved upward while the scraping blade 26 is in the stored state shown in FIGS. 1 to 3, the spring part 20
is pressed and brought into contact with the contact point 21, and the motor 2 is driven. When the motor 2 rotates, the drive element 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 moved upward, the scraping blade case 23 in which the scraping blade 26 is housed moves upward along the side of the main body case 1, and is moved to a position close to the main blade 24 as shown in FIG. It moves upward and the scraping blade 26 rotates and protrudes to the side.

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 operating handle portion 29 is further moved upward, the scraping blade case 23 will go up, 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 shaft (FIG. 3C).
Thereafter, by further moving it upward, the scraping blade 26 rotates and becomes in a protruding state (D in the figure).

In this manner, the hair guard protrusion 23a also moves upward as the scraping blade 26 moves upward and rotates to protrude.

In this state, the scraping blade 26 is the main blade 2.
4, and the amount of horizontal protrusion of the shaving blade 26 is sufficient, so there is no risk of accidentally cutting the hair with the main blade 24 during shaving. In addition, in the state shown in FIG.
2 is fitted into the scratching blade 26 and the drive piece 34 provided on the driver 4, power is transmitted to the scraping blade 26, the scraping blade 26 slides back and forth, and becomes ready for use. In this case, a hair guard protrusion 23a protruding from the upper surface of the shaving blade 26 is provided between the shaving blade 26 and the main blade 24, so that it is possible to prevent hair from getting caught in the main blade 24 during use. can.

In addition, since the protrusion 23a has a front-down inclined surface, the hair is difficult to move toward the main blade 24 when cutting.

When the scraping blade 26 is not in use, lower the operating handle 29 to release the lever 27 and the scraping blade case 2.
Due to the spring pressure of the return spring 31 provided at 3, the scraping blade 26 rotates and returns, and the main blade
It is stored in the scraping blade storage section 25 even at a position downwardly away from the blade.

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.

(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, the scraping blade is movable along the side surface of the main body case, and the scraping blade is moved in conjunction with the movement. In an electric razor that can be protruded and stored, the shaving blade has a blade at the tip, a rear end is rotatably supported, and is stored along the main body case at a position spaced downward from the main blade. , a hair guard protrusion that protrudes laterally at a position close to the main blade and protrudes from the upper surface of the crease blade is provided between the main blade and the crease blade, and this hair guard protrusion The movable support part is covered, and the protrusion is not rotatable and moves up and down with the scraping blade, and has a forward-sloping slope at the top. The effect is that it does not become difficult to scratch and is easy to use.

In addition, the protrusion for the hair guard is designed to cover the rotating part of the scraping blade and has an inclined surface, so it is difficult for hair debris to enter when the main blade is used.
The protrusion also serves as a member to prevent the intrusion of beard debris.

In addition, the hair that grows along the face comes in contact with the front-down slope that forms an almost acute angle to the hair, and is pressed toward the face, making it difficult for the hair to move toward the main blade when cutting.
