【技術分野】 本発明は共に櫛歯状の刃を備えた固定刃と可動刃とから
なるとともに、固定刃に対し摺動駆動される可動刃が固
定刃の刃溝に捕らえられた髪を切断する電気バリカン刃
に関するものである。TECHNICAL FIELD The present invention comprises a fixed blade and a movable blade both having comb-teeth-shaped blades, and a movable blade that is slidably driven with respect to the fixed blade cuts hair caught in a blade groove of the fixed blade. It relates to an electric hair clipper blade.

しを招き、毛引きや毛づまりを生じてしまうのである。An example of a conventional electric hair clipper blade is shown in FIG. The movable blade 3 is arranged on the fixed blade 1 fixed to one surface of the base 6, and the movable blade 3 is pressed against the fixed blade 1 by the pressing spring 7. The movable blade 3 is provided with a connecting member 8 for connecting to a driver (not shown) that reciprocally vibrates.
Each of the fixed blade 1 and the movable blade 3 is formed in a comb tooth shape, and the movable blade 3 driven by reciprocating vibration cuts the hair caught by the blade groove 2 of the fixed blade 1. By the way, in the hair clipper blade configured in this manner, the comb-teeth-shaped cutting edges of the fixed blade 1 and the movable blade 3 are both formed to be as wide as possible in order to maximize the range in which they can be cut at one time. Therefore, the hair cannot be cut at both ends, which sometimes causes the user to feel pain. This is due to the following reasons. That is, the amplitude of the movable blade 3 is set so as to traverse the two blade grooves 2 of the fixed blade 1 as shown in FIGS. The hair 5 caught in the groove 2 has an opportunity to be cut 4 to 5 times by the movable blade 3 while the movable blade 3 makes one reciprocation, while the blade formed at the end of the fixed blade 1. The hair 5 taken in the groove 2 has only two opportunities to be cut during one round trip of the movable blade. The amplitude of the movable blade 3 moves only to the position shown by the solid line at the time of overload even if there is an amplitude amount enough to move to the position shown by the imaginary line in FIG. 8 when there is no load. Due to the difference in the number of occasions, the hair 5 is left uncut at the end portion as shown in FIG. 9, resulting in hair pulling and hair clogging.

る。The present invention, therefore, comprises a fixed blade and a movable blade both of which are provided with comb-shaped blades, and the movable blade that is slidably driven with respect to the fixed blade cuts the hair caught in the groove of the fixed blade. In the hair clipper blade, the area of the part included in the mutual sliding surface of the fixed blade and the movable blade in the blade groove of the fixed blade or the movable blade is smaller at both ends than in the central portion The feature is that the amount of hair cut at both ends is reduced in advance. The present invention will be described in detail below with reference to the illustrated embodiments.
The figure shows one embodiment, and of the fixed blade 1 and the movable blade 3 both of which have comb-teeth-shaped blades, the blade grooves 2 formed in the fixed blade 1 and located at both ends 20 Only shallow (H '
<H). That is, the areas of the blade grooves 20 at both ends are made smaller than the areas of the other blade grooves 21. Therefore, when the hair caught in the blade groove 2 of the fixed blade 1 is cut by the movable blade 3, the amount of hair caught in the blade grooves 20 at both ends is larger than the amount of hair caught in the other blade grooves 21. The number of hair cutting opportunities is not at least large, and the hair caught in the blade groove 20 is surely cut. In the embodiment shown in FIG. 2, the blade grooves at both ends of the fixed blade 1
By making the opening width of 20 smaller than the width of the other blade groove 21 (D <d), the area of the blade groove 20 is reduced. Further, in the embodiment shown in FIG. 3, the plurality of blade grooves 2 located at both ends of the fixed blade 1 are designed so that the depth gradually becomes shallower from the central portion to both ends. Instead of changing the area of the groove 2 of the fixed blade 1, the movable blade 3
The area of the blade groove 4 may be changed. In the embodiment shown in FIG. 4, the area of the blade groove 40 located at both ends of the movable blade 3 is defined as the protrusion amount of the end side protrusion 42 of the pair of protrusions 42 forming the blade groove 40. By making it smaller, it is smaller than the area of the other blade groove 41. Further, in the embodiment shown in FIG. 5, the depths of the blade grooves 40 at both ends of the movable blade 3 are made shallower than the other blade grooves 41. Further, in the embodiment shown in FIG. 6, a projection portion surrounding the blade groove 4 is formed.
The area of the blade groove 4 is adjusted by gradually reducing the amount of protrusion of 42 from the central portion to both ends. In this way, the area of the blade groove 40 at both ends of the movable blade 3 is set to the other blade groove 41.
If the area is smaller than the area of
Even if the amount of hair captured by 20 is large, only a part of the hair can be cut into the area where the hair can be cut, so that the load on the reciprocating motion of the movable blade 3 is small and the amount of hair cut at both ends is small. However, there is no chance that your hair will bite you. In the above, only the blade grooves 2, 4 at both ends of the fixed blade 1 or the movable blade 3 are set to have a small area, but both the fixed groove 1 and the movable blade 3 have the blade grooves 2 at both ends. ,
The area of 4 may be reduced. Incidentally, the area of the blade groove here refers to the area of the portion that contributes to the cutting of the hair which is the original function, and for example, even if the back end of the blade groove of the fixed blade is deeply inserted,
The area referred to here does not include a portion deeper than the deep end of the blade groove of the movable blade. That is, only the effective cutting area (the area of the portion included in the mutual sliding surface of the fixed blade and the movable blade) is referred to.
以上のように本発明においては、髪の切断機会が中央部
に比して少ない両端の刃溝の面積を、中央部の刃溝の面

するものである。As described above, in the present invention, the amount of hair entering the region that can be cut by making the areas of the blade grooves at both ends, which have less chance of cutting hair than the central portion, to be smaller than the area of the central blade groove. For this reason, hair is not cut off at the end and it is not bitten to cause hair pulling or hair blockage, and it exhibits good sharpness.
