Description

Description: TECHNICAL FIELD The present invention relates to a hair clipper that includes a fixed blade and a movable blade and reciprocates the movable blade with respect to the fixed blade to cut hair and long beards.

[Background Art] When a hair clipper is used to cut the hair or align the edges as shown in Fig. 10, if the width of the blade remains wide, it will cut to places other than what should be cut. There is also a risk of the blade hitting the nose. For this reason, as shown in FIG. 11, a blade tip cover 3 which is attached to the tip of the main body 1 provided with the fixed blade 20 and the movable blade 21 to cover the widthwise half of the blade tip is detachable. However, in this case, although the effective blade width becomes narrower and the blade can be used for the above-mentioned purposes, the blade cover 3 is attached to the fixed blade 20 and the movable blade 21 so as to cover it. The thickness t of the portion located in front of the cutting edge is large, and therefore, when the lower portion of the mustache is cut, the beard near the skin cannot be cut.

[Object of the Invention] The present invention has been made in view of such a point, and an object of the present invention is to use it for cutting a mustache because the effective blade width can be narrowed as necessary. Another object of the present invention is to provide a hair clipper that can reliably cut beard near the skin within the effective blade width.

DISCLOSURE OF THE INVENTION In the present invention, however, the holding member that holds the fixed blade and the movable blade that is slidably driven with respect to the fixed blade has the tip aligned with the blade edge of the fixed blade or the movable blade. The blade has a feature that a blade cover that is slidable in the blade direction is provided between a protruding position that partially covers the width direction and a retracted position that exposes the blade edge. Alternatively, the effective blade width is narrowed by covering the blade edge of the movable blade.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. A main body 1 having a driving motor built therein has a blade block 2 mounted at its tip. In this blade block 2, a comb tooth-shaped fixed blade 20 is fixed to the inner surface of a substrate 22, and a comb tooth-shaped movable blade 21 is slidably attached in the width direction. The movable blade 21 is reciprocally driven by the output of the conversion member that converts the rotation of the motor into a reciprocating motion.

A pair of left and right blade edge covers 3, 3 are attached to the outer surface of the substrate 22 of the blade block 2. These cutting edge covers 3 and 3 are arranged in the recesses 23 and 23 formed on the outer surface of the substrate 22, and the projections 30 projecting from both side edges are recessed in the recesses 23 as shown in FIG. By engaging with the groove 24 of the side wall, as shown in FIG. 2, with respect to the substrate 22, between the projecting position that projects forward and covers the blade edge of the fixed blade 20 and the retracted position that exposes the blade edge. The projection 25 projecting from the bottom surface of the recess 23 engages with a recess (not shown) on the inner surface of the blade cover 3 at both of the above-mentioned positions, so that the blade edge is in the protruding position. The blade edge cover 3 is positioned so that the tip edges of the blade edge cover 3 are aligned. The pair of blade tip covers 3 and 3 here are supposed to be able to cover approximately half each of the blade tips of the fixed blade 20 in the width direction.

Then, when cutting under the mustache, as shown in FIG. 4 or 5, one of the blade tip covers 3 may be projected to cover one half of the blade tip of the fixed blade 20. As a result, the effective blade width is halved, so that it is possible to mow only the necessary portion, and at the same time, it is easy to finish it into a curved line, and it is possible to prevent the blade from hitting the nose. The blade cover 3 is slid to cover only one surface of the fixed blade 20, and the blade cover 3 does not protrude from the edge of the fixed blade 20. Can be cut into Moreover, since the left and right halves of the cutting edge are shared by the pair of cutting edge covers 3 and 3, by making each cutting edge cover 3 correspond to the beard on the left half and the beard on the right half of the face, It is easy to match the shape. In the same way, you can get a nice finish when you align the edges.

Of course, when cutting a beard, a pair of blade covers 3,
You can move 3 together and use it while maintaining a wide blade width. FIG. 6 shows a state in which an attachment 5 for controlling the cutting height is attached when cutting a beard.

Another embodiment is shown in FIG. 7 and FIG. Although this has only one blade tip cover 3, it can be slidable to the left and right in the blade width direction so that either half of the blade tip of the fixed blade 20 can be covered with the blade tip cover 3. The protrusion 34 protruding from the cutting edge cover 3 is slidably engaged with the L-shaped groove 26 provided on the bottom surface of the recess 23 of the substrate 22. The cutting edge cover 3 moves along the groove 26.

Further, the embodiment shown in FIG. 9 shows that the number of the blade tip covers 3 is three, and each blade tip cover 3 is covered by a slide when the width direction of the blade tip of the fixed blade 20 is divided into three. In this case, if the two blade edge covers 3, 3 are slid together to cover the blade edge of the fixed blade 20, the effective blade width becomes further narrower than that shown in the above embodiment, and as shown in the figure. It is also possible to set so that cutting can be performed using only the central portion in the blade width direction.

The blade edge covers 3 in the illustrated examples are on the fixed blade 20 side and cover the blade edge of the fixed blade 20, but may cover the blade edge on the movable blade 21 side.

[Advantages of the Invention] As described above, in the present invention, a part of the fixed blade or the movable blade in the width direction is slid by sliding the blade cover that is slidable with respect to the holding member of the fixed blade and the movable blade. Therefore, in the state where the cutting edge is not covered for this reason, it is possible to efficiently align the length of beard growing in a wide range like a beard, and to cover a part of the cutting edge When the width is narrowed, it is easy to finish it under the mustache or to align the hairline so that it has the desired curved shape, and the risk of hitting the nose blade can be eliminated, and When narrowing the effective blade width, the blade tip cover aligns its tip with the blade edge and does not protrude beyond the blade edge, so the blade cover interferes with the beard cut near the skin. There is no such thing.
