Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric razor which is movable along a side surface of a main body case and has a wrinkle blade which can be projected and stored in the main body case.

[0002]

2. Description of the Related Art There are various types of electric razors, but in general, electric razors with a wrinkle blade are preferred because of their convenience. As for how to use the kizori blade, usually, the raised parts are aligned, for example, a relatively good beard extending to the chin is used as the front step of continuous shaving,
First of all, it is used for cutting with a wrinkle blade.

In the former use, it is desired that the main blade does not get in the way and the hair is accidentally cut when the wrinkle blade 6 is used. Further, as the latter method of use, it is preferable that when the long beard is first cut with the wrinkle blade and then the main blade is finished to be short, the wrinkle blade does not get in the way.

By the way, as an electric razor having a conventional wrinkle blade, for example, as shown in FIG.
The wrinkle blade 64 is movable with respect to the main body case 63 so that the wrinkle blade 64 moves to a position close to the main blade 62, and as shown in FIG.
Is stored below the main blade 62, and the wrinkle blade 61 is the main blade 6
Some of them are designed to project and rotate below 2.

However, in the former one, since the wrinkle blade 64 is always in the state of protruding laterally,
The appearance is not good, the crevice blade 64 is easily damaged when it hits or falls on another object, and the blade portion of the tip of the crease blade 64 after movement is extremely close to the main blade 62. There is a risk that the main blade 62 will cut the hair when using the wrinkle blade 64, and while the latter one solves the problems of appearance and damage described above, the attitude of the body case 63, that is, the wrinkle blade When the contact angle of 61 is changed, the wrinkle blade 61
Although it is separated from the main body case 63 to the side, its position is considerably lower than the main blade 62, so in the end, when the kizori blade 61 is used, the main blade 62 cuts the hair and the usability remains inconvenient. ing.

Therefore, in order to solve these problems, as shown in Japanese Patent Laid-Open No. 56-57478, the wrinkle blade is movable up and down and is pivotally projected in conjunction with the upward movement. Things have been proposed.

[0007]

However, in this type of electric razor, the outer blade is formed in an arch shape and its end portion is attached to the frame, and the outer blade is attached to the frame. The blade hole is opened to the part, when shaving with the main blade, it is used extensively from the top to the end of the outer blade, especially in difficult-to-use parts such as the chin,
The edge of the outer blade is often applied to the skin and contributes to shaving. However, in the electric razor disclosed in Japanese Patent Laid-Open No. 56-57478 described above, even when the wrinkle blade is stored, the wrinkle blade is located in the cutting area of the outer blade, and when the main blade is used, the wrinkle blade is used. I had a problem getting in the way.

The present invention has been proposed in view of the above points, and an object of the present invention is to prevent the main blade from cutting the hair when using the wrinkle blade, and to use the wrinkle blade when using the main blade. Is to provide an electric razor that is completely out of the way.

[0009]

In order to achieve the above object, the present invention provides an outer blade having an arch-shaped end portion attached to an outer blade frame and an inner blade slidably contacting the inner surface of the outer blade. A main blade consisting of is provided on the upper part of the main body case, and the wrinkle blade can be moved up and down along the side surface of the main body case,
And in the electric razor that can project and store the kizori blade in conjunction with movement, the kizori blade is stored along the main body case at a position lower than a straight line connecting the top of the outer blade and the end of the outer blade frame. It is characterized in that it is configured to project laterally at a position above the straight line.

[0010]

When the electric razor of the present invention is not used for the wrinkle blade, the electric razor is located at a position below the main blade, that is, below the straight line connecting the top of the outer blade and the end of the frame. The blade is stored with the blade facing downward, and when the Kizori blade is slid upward from this state, it protrudes sideways so that the blade tip is close to the main blade and at a position lower than the main blade, so that the blade tip separates from the main blade. The main blade does not get in the way when using only the wrinkle blade so that the hair is not accidentally cut. Further, since the wrinkle blade is sufficiently moved upward and is projected to the side, the main blade 24 does not interfere with the use of the wrinkle blade 26.

On the front surface of the main body case 1, a switch handle 14 for performing ON / OFF operations 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. Has been.
A waterproof rubber 18 is attached to the opening 17 of the main body case 1 between the switch frame 16 and 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 by operating the switch handle 14, the switch spring 20 on the base 3 is pressed to bring the contact 21 and the switch spring 20 into contact with each other. And constitutes an electric circuit to drive the motor 2.

As shown in FIG. 2, a pair of projecting pieces 22 facing each other are arranged on the upper part of the switch frame 16, and a wrinkle blade case 23 is slidably mounted between the projecting pieces 22. ing. Below the main blade 24 composed of the outer blade 13 and the inner blade 11 that is in sliding contact with the inner surface thereof,
As shown in FIG. 1, a wrinkle blade accommodating portion 25 is formed in the inside of the blade, and a rear end portion of the wrinkle blade 26 having a movable blade and a fixed blade is rotatably supported therein. The kizazori blade 26 is formed on the top of the outer blade 13 and the outer blade frame 1.
It is housed along the main body case 1 at a position lower than the straight line X connecting the two ends.

A lever 27 for pivotally projecting the wrinkle blade 26 is provided on one side of the wrinkle blade 26 (see FIG. 2).
The lever 27 is provided with a long hole 27a to which a boss 26a attached to the wrinkle blade 26 is engaged. A click member 28 is disposed behind the switch handle 14 below the wrinkle blade 26, and the click member 28 extends to a position overlapping the click member 15 of the switch handle 14. Further, as shown in FIG. 1, an operation handle portion 29 of the wrinkle blade case 23 is extended to one side of the wrinkle blade case 23 to a side surface portion of the main body case 1.

A return spring 31 for the wrinkle blade 26 is provided between the lower portion of the lever 27 and the rib 30 formed in the lower portion of the wrinkle blade case 23, and the spring of the return spring 31 is provided. The pressure prevents rattling when the wrinkle blade 26 is stored. Further, as shown in FIG. 5, which will be described later, a protruding portion 27b is provided at a substantially central portion of the lever 27 so as to function as a stopper of the lever 27 when the wrinkle blade 26 is rotationally protruded. Further, behind the crevice blade storage portion 25, a drive rod 32 is provided for driving the crevice blade 26 by engaging the crevice blade 26 and the driver 4 when the crevice blade 26 is rotated and projected. The main blade 24 is the wrinkle blade 2
The structure is inclined to the 6 side.

Next, this operation will be described. Now, when the switch handle 14 is moved upward from the housed state of the wrinkle blade 26 shown in FIGS. 1 to 3, the protrusion 20 provided on the switch handle 14 presses the spring portion 20 and the contact 21.
The motor 2 is driven in contact with. When the motor 2 rotates, the driver element 4 reciprocates through the eccentric cam 7, the inner blade 11 vibrates, and only the main blade 24 operates in cooperation with the outer blade 13. In this case, since the main blade 24 is inclined,
When using the main blade 24, it is easy to apply the top that cuts best to the skin.

Then, when the operation handle portion 29 is moved upward, the crevice blade case 23 in which the crevice blade 26 is housed is stored.
