Description

DETAILED DESCRIPTION OF THE INVENTION This book I#l is a book about a hair cutter that can perform plow cutting in addition to normal hair cutting.

Conventionally, the following two types of books have been provided as books of this type. In other words, as shown in Figure 41, the fixed blade (4
) is lined up at the tip! The cut grooves 6) are all the same size, and cuts are made between the cutting edge (7) of the movable blade (6) and the fixed blade (4).
) The hair is cut by cutting the hair with the full blade groove (6) of the attached blade (9). The type in which the hair is cut by closing the blade groove +5) of the fixed blade 14) excluding the east part and cutting the hair with the blade # (6) that overlaps with the notch side and the OT movable blade (6), and the type shown in Figure 3. Fixed blade 14 as shown in
) blade 416) shallow ml (5Jll) and deep a (5b
) and 24, and move the movable blade (B) forward by closing the movable blade 16) so that it can move forward and backward with respect to the fixed blade (4).
If L, the cutting edge (7) of the movable blade (6) and the full groove (6) of the fixed blade (4) overlap to perform cutting, and when the movable blade (II) is moved back, the cutting edge of the movable blade (61) 7) is a full blade groove (6)
Of these, there are two types: a type that allows plowing to be carried out only by overlapping the - (5b). By the way, the depth of blade # (6) of fixed blade (4) affects the cutting load. In other words, the depth of blade # (5) means that the scissor angle with the cutting edge (7) of movable blade (6) Due to the relationship, the blade groove (
The opening width of 6) has also become larger, and a large amount of hair has been created.
In addition, the width of blade # (6) becomes narrower in the deep part of blade $ +61, so this large amount of hair is squeezed and becomes denser, which increases the load to cut it. becomes larger. Now, when comparing the above two types (4), in the one shown in Fig. 1, the blade groove (6) of the fixed blade 14)
is rather shallow <, the cutting load is the same during plowing as shown in Figure 3. (5b) is used only to cut the hair, so #14
High density hair 1 as shown in the picture! It is necessary to cut off the prisoner, and in particular, hair cutters use the cutting method of pressing the blade directly against the hair and pulling it downward along the direction of the hair, so the condition shown in Figure 4 is used. This occurs continuously, requiring a considerably high cutting capacity, and it is necessary to have a cutting capacity that is greater than the cutting capacity required for force-cutting.

As is clear from the above points, it is the first in terms of cutting load.
It is preferable to use the attachment (9) shown in the figure to perform plow mowing, but in actual use, there are four points when using this attachment (9) as follows. In other words, the attachment (9) is installed as close as possible to the fixed blade (4), as shown in Figure 2.
4), there is a considerable distance in rJH between the attachment (9) and the contact surface between the fixed blade (4) and the movable blade (6) where actual cutting is performed. For this,
As shown in Figure 2, the attachment (9
), hair particles are introduced into the full blade groove (6) and are cut by the cutting edge (7) of the movable blade (11) and the full blade groove (6). This results in a normal cut rather than a hair clipping, and in other words, the blade tip must be placed at the right angle to the hair trap to achieve a consistent cut, which is a limitation in use for amateurs. There are many, and it is very difficult to use. On the other hand, the type shown in FIG. 3 does not have the problems of the one shown in FIG. 1, and would be extremely preferable if the above-mentioned cutting load could be solved.

The present invention was developed in view of these points, and its purpose is to make it easy to use since there is no need to accurately maintain the angle of application of the blade to the hair during shearing, and to provide an indispensable tool for hair cutting. To provide a hair cutter capable of performing 4 plowing operations with good sharpness without having to have a considerably high cutting capacity higher than the average cutting capacity.

The present invention will be described in detail below based on illustrated embodiments. This hair cutter consists of a main body 11), a blade block (3), and an upper presser block 12).
The blade block (3) is attached to the upper surface of the front end of the blade block (3), and the upper presser block (2) is further attached to the upper surface of the blade block (3). A mounting recess (lI) for the blade block (s) is provided on the upper surface of the front end, and an eccentric The axis II is protruded, and the rear part 11&C mounting spring II is arranged.

The protrusion/ura on the rear end is inserted into the retaining hole 341 of the main body (11), and the mounting spring-TJs is engaged with the locking surface 4 (clearly), so that it is inserted into the mounting recess (1) of the main body (1). The blade block (3) attached to U) is attached to the mounting base and
The fixed blade (
4) and OT @ blade (6), when the movable blade (6) is fixed to the front end, the drive rod (17) in which the vertically long slit 4 at the rear end engages with the eccentric shaft jI#; A pair of pressing springs i8) that press the movable blade (6) against the rigid blade (4) 18)
% Insect presser block (a pair of presser AI that interlocks 11 and movable blade (6)) + 40, fixed blade (
4) is fixed to the mounting base +30 by increasing the pin on the front 4F surface of the mounting base 3υ, and the movable blade (6) is fixed to the fixed H (4).
The rotation of the eccentric tapered 4 is arranged on the lower surface of the slit I11.
It reciprocates left and right by a drive rod 0η that reciprocates at . Each press spring (8) has one end locked in a recessed barrel at the front end of the drive rod αη, and the other end locked in a cross-shaped slit in the leg of the lever 141), and is twisted into a coil shape. It is formed. The base of each lever (tea tel) is rotatably supported by a lever provided on the mounting base 3υ, and the upper piece (6) forming an obtuse angle is inserted from the hole on the mounting base 3υ. Protrudes from the top of the mounting base aυ.

At this time, a piece connected to the drive rod (I'l) of the presser spring (8) protrudes from the mounting base II, and the nine contact pieces are still in contact with the top surface of the tank 1, and the movable blade is moved using this contact part as a fulcrum. (6) Fixed blade (
4) A spring force is formed to push up the blade block i3), which maintains the contact pressure between the movable blade (6) and the fixed blade (4). +1
)'s 11r4 part Kjl! ! As shown in Figure 49, the insect suppressor block (2) is placed on the cover.
An O-ra (2) whose both ends are supported by pins (E) and is installed rotatably around an axis at the upper part of the front end opening of the cover, and an O-ra (2) which is integrally formed at the lower edge of the front end opening of the cover. A total of four protrusions (to) provided on both sides of the inner surface of the cover are formed from the blade block (21) for combing.
) One recess 4 provided in the front and back direction on both sides of the mounting base 13K)
1114c between the inner surfaces of the cover (2) and the inner surface of the cover (2).
The tips of the attached springs are click-engaged with the recesses 1 provided on both sides of the mounting base 130, so that positioning in the forward and backward movement is not possible. When the IL nine caterpillar push block (2) attached to the main body ill is moved forward, the bridge section is positioned below the movable blade (6), and the O-ra (2) is positioned above the fixed blade 14). 0-ra (2) from above the fixed blade +61 and from below the movable blade (4).
And Hashibe 0! υ each retreat backwards.

Here, the fixed blade (4) has two types of blade grooves (6) arranged in rows at its front end, shallow grooves (5a) and deep grooves (5b), as shown in Figure 3. When cutting, move the movable blade (6) forward and overlap the blade tip (7) of the movable blade (6) with the full force #11161 of the fixed blade (4), and when mowing, move the movable blade (6) forward. ) and make a deep groove (5b).
The cutting edge (7) of the movable blade (6) is made to overlap only the blade groove (6) of the movable blade (6), but in this embodiment, the movement of the movable blade (6) is linked to the movement of the insect presser block. In other words, when the insect press block (2) is moved backward, the suppression protrusion (protrusion) provided on the inner surface of the cover of the insect press block (2) will move as shown in Figure 1(b). The movable blade (@) moves forward via the rounded press spring (8) that presses the upper surface of the rear end of the upper piece (6) of 6) and rotates the tip of the leg (41) forward and the drive rod (17). And counter pressure insect press block (2)
When the lever (1) is moved forward, the suppression projection (6)
) is pressed against the upper surfaces of both ends to rotate the tip of the leg (tea) backwards, and the movable blade (6) is pulled back together with the driving rod (IT) by the pressing spring 18).

Now, as described above, when the insect presser block (2) is moved backward, the OT movable blade (6) moves forward to deal with the cut, and when the insect presser block (2) is moved forward, the movable blade (6) moves forward.
The structure is designed to deal with plow mowing by retracting the mowing block, but the insect suppressor block (2
), the leading edge of the bridge @υ and 0-ra rigid is a fixed blade (
IIcTo is located approximately at the same position as the front edge of 4).If you perform pruning in this state, the bridge part shiυ and the O-ra wire will be the # of the fixed blade (6) used for cutting the hair. The cutting part between the deep part of the blade groove (6) of the blade (5b) and the cutting edge (7) of the movable blade (6) is 51E11.
As shown in the figure, it is placed at a certain distance from the scalp ■ to prevent more hair than necessary from being introduced into the blade. Also, this shaving is usually done by stroking the hair with a hair cutter from top to bottom along the flow of the hair, but the hair is combed and trimmed with the 2υ vibration part, and there is no need to use a separate comb. The hair that is no longer tangled is the blade #
(i), it is possible to perform uniform cutting without hair traps being caught by the blade, and it also prevents hair particles that are clumped and dense from being introduced into blade # (6). This limits the amount of hair trapped deep in the blade groove (6) of 4g (5b). Therefore, when the movable blade (6) cuts the hair that has reached the deep part of the blade groove (6) of this depth # (5b), the cutting load does not become very high. Moreover, in this embodiment, the cutting ability is made suitable for cutting and plowing by advancing and retreating the l5TIlb blade (6), so even if the cutting load during plowing becomes large, the cutting ability remains sharp. never falls. As shown in FIG.
Pressing spring (8) for pressing toward the fixed blade (4)
A pressing spring (8) is provided between the mounting base to which the abutting piece A or the fixed blade (4) is fixed, which serves as the fulcrum that generates the spring force at K.
is formed so that the distance l between the fulcrum and the point of action changes as the movable blade (6) advances and retreats by moving forward and backward together with the movable blade (6). distance! is long and the spring force is small, but when the movable blade (6) is moved back and the distance 1 is shortened at 9 o'clock, the spring force becomes large, and when mowing, the contact pressure between the fixed blade +61 and the movable blade (4) is high. This improves cutting ability.

Similarly, in the above embodiment, a bridge section circle is provided on the bristle presser block and a row 54 is provided on the book, but this 0-rad bridge section 0
This book was created in order to make the function of the 1st part more effective, and it is possible to use only the horizontal part @ phantom, and it is also possible to create a pair of upper and lower bridge parts @ υ shi υ by providing a lateral part υ instead of 0 - A (2). It is also possible to provide a comb part (2υ only) above the fixed blade (4) and movable blade (6).Also, the hair presser block (2) equipped with the comb part @υ can be moved back and forth with respect to the main body +11. I have shown the turret with a flexible shape, but when mowing the plough, the hair presser block (!) can be attached to the main body +
1) It's a good book because it's removable.

As described above, in the present invention, when the movable blade is made to move forward and backward with respect to the fixed blade, the round blade grooves are arranged in rows on both edges of the fixed blade, and the round blade grooves are formed into shallow grooves with a depth of 11HtL. Since it was composed of
Not only can you use the spinning speed and plowing properly, but you can also adjust the blade's contact with the hair during plowing!
The comb is very easy to use, as the comb is usually used for combing by changing the length of the comb. If the amount of hair that is introduced into the deep groove-shaped blade groove and reaches the deep part of the blade groove is regulated, and the cutting load when cutting hair between the deep part of the deep groove-shaped blade groove and the cutting edge of the movable blade is light. This is a book that will help you get the best sharpness when mowing.
