Abstract

PURPOSE:To improve the drop resisting strength of the end part side, and also, to make the skin contact property excellent by thickening the blade thickness of a fixed blade in the end part side against the center part for determining the cutting left height, in the hair cutter blade in which the fixed blade is formed by fine ceramics. CONSTITUTION:Two pieces are positioned in line symmetry against the center shaft of a base plate and with regard to each of them, one end and the other end are hooked and attached to an engaging part provided on the base plate 3, and the engaging part 4a of a guide plate 4 attached to a movable blade 2, respectively. By this attachment, a fixed blade 1, a movable 2 and a holder spring are subjected to blocking, and also, the movable blade 2 is supported so as to be roughly freely reciprocatable against the fixed blade 1. Blade thickness of a first cutting blade 1a is formed so as to be gradually thicker toward the end part 1b side from the center part. Therefore, the outside surface of a first cutting blade 1a of the fixed blade 1 becomes a recessed shape. Consequently, the contact pressure distribution of the fixed blade 1 and, for instance, the head part becomes gentle, and the blade softens the skin contact, and also, comes to easily run along the head.

ァインセラミックスで形成されている。As shown in Figs. 3 and 4, the conventional hair cutter 7 blade is attached to one longitudinal end of the hair cutter main body, which has a built-in motor and a drive unit having an eccentric shaft as its output shaft. , is driven by engaging the scale portion 4b of the guide plate 4 with the eccentric shaft. This hair cutter blade has a comb-shaped first cutting blade 1.
It is formed from a fixed blade 1 having a fixed blade 1 and a movable blade 2 having a comb-shaped second cutting blade 2a that is pressed against the fixed blade 1 and slides back and forth.
In addition, since the blade thickness of the first cutting blade 1a of the fixed blade 1 tapers toward the tip, the tip of the second cutting blade 2a of the movable blade 2 is cut to a predetermined height to leave the hair uncut. It is arranged at a predetermined blade thickness of the fixed blade 1. And fixed blade 1
- At least the fixed blade 1 is made of fine ceramics in order to improve the sharpness and life of the movable blade 2 compared to those made of metal.

中央部分に対し、端部側を厚くした構成としている。[Means for Solving the Problems] In order to achieve the above-mentioned object, the hair cutter blade of the present invention includes a fixed blade having a comb-shaped cutting edge, and a comb-shaped fixed blade that is pressed against the fixed blade and slides back and forth. A movable blade having a cutting edge, and a fixed blade and a movable cutting blade arranged to cut the hair to a predetermined uncut height, and at least the fixed blade is made of fine ceramics. In the hair cutter blade, the blade thickness of the fixed blade is thicker at the end portion than at the center portion, which determines the uncut height.

定刃１に対して略往復自在に支持される。Reference numeral 2 designates a movable blade, and if it is made of fine ceramics, it is formed in the same manner as fixed blade 1, but if it is made of metal, this second cutting blade 2a is formed by punching and forming a metal plate, and then grinding it. are doing. This movable blade 2 is pressed against the fixed blade 1 using a reaction force of a torsional force of a presser spring (not shown), which will be described later. The presser springs are torsion coil springs, and two of them are located symmetrically with respect to the center axis of the board 3, and each has one end connected to a locking part (not shown) provided on the board 3, and the other end connected to a locking part (not shown) provided on the board 3. is attached to the movable blade 2 by being hooked onto the locking portion 4d of the guide plate 4 attached to the movable blade 2. With this installation, fixed blade 1 and movable blade 2
- The presser spring is made into a block, and the movable blade 2 is supported with respect to the fixed blade 1 in a substantially reciprocating manner.

本発明の要部は、前記固定刃１の第１切刃１ａにある。The main part of the present invention resides in the first cutting edge 1a of the fixed blade 1.

お、両端部１ｂ、１ｂの第１切刃１ａの刃厚のみ厚くす
るようにしてもよい。The thickness of the first cutting edge 1a is gradually increased from the center toward the end 1b. Thereby, the outer surface of the first cutting edge 1a of the fixed blade 1 becomes concave. As a result, the contact pressure distribution between the fixed blade 1 and, for example, the head becomes gentle, making it soft against the skin (as well as making it easier to follow the head. Note that only the blade thickness of the first cutting blade 1a at both ends 1b, 1b) It may be made thicker.

次に、本発明の第２実施例を第２図に基づいて説明する
。Next, a second embodiment of the present invention will be described based on FIG. 2.

本発明の要部は、前記可動刃１の第２切刃２ａにある。The main part of the present invention resides in the second cutting edge 2a of the movable blade 1.

この要部以外の部材は、先に説明した第１実施例と同様
であるので、実質的に同一の部材には同一の符号を付し
て詳細な説明は省略する。Members other than this essential part are the same as those in the first embodiment described above, so substantially the same members are given the same reference numerals and detailed explanations will be omitted.

さを正確に均一化することができる。The tip of the second cutting edge 2a is moved closer to the tip of the first cutting edge 1a of the fixed blade 1 depending on the thickness of the first cutting edge 1a, and closer to the edge where the blade is thicker and farther away from where it is thinner. There is. That is, the first cutting edge 1a is located approximately at a blade thickness portion corresponding to a predetermined uncut height. As a result, the dimension between the tips of the first cutting edge 1a and the second cutting edge 2a becomes smaller from the center of the first cutting edge 1a of the fixed blade 1 toward the end 1b. By doing so, it is possible to more accurately equalize the uncut height than in the first embodiment.

り性の向上が図れる。The hair cutter blade of the present invention increases the cross-sectional area of the cutting edge at the end without reducing the performance of obtaining a predetermined uncut height, increases this permissible notch j, and improves the cutting edge of the fixed blade. The edge of the blade is thicker than the center, and the outer surface of this cutting edge is concave to smooth the contact pressure distribution between the fixed blade and, for example, the head, which improves the impact resistance of the hair cutter blade. You can improve your ability to escape.
