Description

[Detailed description of the invention] This invention relates to a swing-type electric hair clipper equipped with a plow-cutting comb that can be freely moved in and out. To enable a circular cut in a posture without being obstructed by a plow-cut comb.

As shown in Fig. 1, this type of swing-type electric hair clipper has a clipper head 3 pivotably attached to the main body case 1 so that the angle at which the cutting edge touches the head can be adjusted appropriately. ing. In that case, if the plow-cutting comb 14 is provided with a mowing comb 14 that can be moved in and out as shown in FIGS. It would be easier to use if it could be operated with the hand holding 1.

From this point of view, the plow-cutting comb 14 can be freely bent and deformed as the clipper head section 3 swings, and is disposed from the clipper head section 3 to the main body case 1, and the plow-cutting comb 14 is arranged on the main body case 1 side. It is desirable to position the rear end of the main body case so that it can be moved in and out using the fingers of the hand that grips the main body case.

However, as it is, the plow-cutting comb 14 is attached to the support shaft 2a, which is the pivot point for swinging the hair clipper head 3.
2b, when the middle part of the plow-cutting comb 14 bends and deforms as the clipper head section 3 swings as shown in FIG. R1 draws an arc shape that gradually moves away from the movement trajectory R2 of the front end of the clipper head 3, and the plow teeth 14a at the tip of the plow comb 14 protrude from the front end of the clipper head 3. occurs. When the plow tooth 14a protrudes in this way, the plow tooth 14a
Since the movable blade 10 is covered by the movable blade 10, it becomes impossible to use a circular cut.

Therefore, the present invention aims to simplify the operation of moving the plow-cutting comb in and out by disposing a plow-cutting comb that can be bent and deformed from the head of the clipper to the main body case. In addition, by providing an adjusting means for correcting the protruding length by retracting the plowing comb by the length by which the plowing comb bends and deforms and protrudes as the clipper head rotates upward. Even when the head of the clipper is placed in an upward position, the plow-cutting comb does not cause any hindrance to the round cut.

The details will be explained below based on the drawings. The drawings illustrate the electric hair clipper according to the present invention,
The main body case 1 of this is a long box shape that is long in the front and back direction.
At the front end of this, the clipper head part 3 is attached to the left and right support shafts 2.
It is attached so as to be freely rotatable in the vertical direction around a and 2b. Specifically, the clipper head part 3 is in the basic position (third position) in which it is in a straight line in front of the main body case 1.
(Fig. 4) and upward position (Fig. 4). One of the left and right support shafts 2a, 2b is integrally molded on the main body case 1 side, and the other support shaft 2b also serves as a swing lock button.
As shown in FIGS. 7 to 9, it is fitted into the shaft hole c of the main body case 1 in a non-rotating manner and retractable through a protrusion a protruding from the circumferential surface, and the protrusion a is connected to the clipper head section. By selectively engaging one of the recesses b provided at two positions on the 3 side, the hair clipper head 3 is held in the above-mentioned straight-line basic position and upward position, respectively. At this time, spindle 2
The state in which the protrusion a of the protrusion b is engaged with the recess b is maintained by the biasing force of the spring 21, and the clipper head portion 3 cannot be oscillated unless this state of engagement is released. The engagement state by the spring 21 is released by pressing the support shaft 2b toward the inside of the case to remove the protrusion a from the recess b. FIG. 8 shows the released state.

In FIGS. 2 and 3, a motor 4 is built into the main body case 1, and an eccentric pin 7 is provided on an eccentric cam 6 fixed to the motor shaft 5 so as to project forward. On the other hand, a vibrator 8 is installed inside the hair clipper head 3, a lever 9 protruding from the front end of the vibrator 8 engages a comb-shaped movable blade 10, and a comb-shaped fixed blade is placed below the movable blade 10. 11 is attached via the holder 12.
Then, the eccentric pin 7 is engaged with the vertically long groove 13 formed on the rear end surface of the vibrator 8, and the vibrator 8 is moved left and right by the drive of the motor 4 via the eccentric cam 6 and the eccentric pin 7. This vibration causes the movable blade 10 to reciprocate from side to side on the upper surface of the fixed blade 11.

A plow-cutting comb 14 is attached from the inner surface of the upper wall 3a of the hair clipper head 3 to the inner surface of the upper wall 1a of the main body case 1 so as to be slidable in the front-rear direction. This plow-cutting comb 14 has plow teeth 14a in which shallow grooves 15 and deep grooves 16 are arranged alternately on the left and right at the front end of a band-shaped handle 14b. It moves in and out of the gap between the front end and the cutting edge of the movable blade 10 located below this. The handle body 14b is configured such that at least its middle portion is flexible and deformable as the hair clipper head section 3 swings.

Thus, in the present invention, the plow-cutting comb 14 is bent and deformed as the clipper head 3 rotates upward, and the protruding length is corrected by operating the plow-cutting comb 14 backward by the length that the plow-cutting comb 14 protrudes and moves. This adjustment means prevents the plow teeth 14a of the plow comb 14 from protruding from the front end of the upper wall 3a as the clipper head 3 rotates upward.

That is, in FIG. 7, as a means for correcting and adjusting the protrusion length of the plow-cutting comb 14, a slide plate 17 is slidably coupled to the rear end of the handle 14b by a predetermined stroke S in the front-rear direction, and these handles 14b
A spring 18 is applied between the handle body 14b and the slide plate 17 to always draw the handle body 14b and the slide plate 17 toward each other. A lock plate 19 which is approximately Z-shaped in plan view is pivoted to the handle body 14b so as to be horizontally swingable in the left-right direction using a shaft 20 as a fulcrum. An operating portion 19a provided at the rear of the shaft 20 of the lock plate 19 is removably engaged with a notch 17a provided in the slide plate 17, and an action portion 19a provided at the front of the shaft 20 of the lock plate 19 The operation part 19b is the clipper head part 3
Groove 24a of pressing piece 24 provided on one support shaft 2b of
It is slidably engaged in the front-back direction. A spring 22 is applied between the lock plate 19 and the handle 14b, and the spring 22 swings and biases the lock plate 19 so that its operating portion 19a always engages with the cutout portion 17a.
When the action part 19a of the locking plate 19 engages with the notch 17a, the plow-cutting comb 14 is kept extended to the full stroke S, and when the engagement is released, the rear end 14c of the plow-cutting comb 14 moves to the slide plate 17. The shortened state is maintained by the tensile force of the spring 18.

The outer surface of the main body case 1 is marked with figures 1 and 2.
As shown in the figure, the operating knob 23, which also serves as a switch, is in two stages, a first protruding position B and a second protruding position C, which are forward of the normal first retracted position A, and a second retracted position, which is rearward from the first retracted position A. Only one stage is provided in D so that it can slide freely. This operation knob 23 has a joint 23a, and the joint 23a connects to the joint 1 on the slide plate 17 side.
7b to move the slide plate 17 integrally. A lock spring 26 and a lock release button 27 are attached to the operation knob 23, and in the first retracted position A, the protrusion 26a of the lock spring 26 abuts and engages with a stopper part 28 provided on the main body case 1 side. You cannot move further back than this. In order to retreat from the first retreat position A to the second retreat position D, the lock release button 27 must be pressed to elastically deform the lock spring 26 and remove the protrusion 26a from the stopper portion 28, as shown in FIG. No.

Now, as shown in FIGS. 2 and 3, the clipper head portion 3 is in a straight posture with respect to the main body case 1, and the operating portion 19a of the lock plate 19 is engaged with the notch portion 17a of the slide plate 17. When cutting, the plow teeth 14a are retracted into the gap between the upper wall 3a of the clipper head 3 and the cutting edge of the movable blade 10, making it possible to perform a circular cut.

From this state, move the operating knob 23 to the first protruding position B.
When the plow comb 14 is slid forward, the plow teeth 14a protrude to the front of the upper wall 3a,
Since both the shallow groove 15 and the deep groove 16 overlap with the cutting edge of the fixed blade 11, the hair introduced into both the shallow groove 15 and the deep groove 16 is shorn. Furthermore, operation knob 2
3 to the second protruding position C, the plow comb 14 moves further forward, the shallow groove 15 protrudes further forward than the cutting edge of the fixed blade 11, and the deep groove 16
Only the blade overlaps with the cutting edge of the fixed blade 11. In this protruding state, only the hair introduced into the deep grooves 16 is shorn.

When the operating knob 23 is returned to the normal first retracted position A, the plow comb 14 returns to its original retracted position and the plow teeth 14a retract into the clipper head 3.

5 and 8 from a state in which the clipper head portion 3 is in a normal state straight with respect to the main body case 1 and the operating portion 19a of the lock plate 19 is engaged with the cutout portion 17a of the slide plate 17. When the support shaft 2b is pressed as shown in the figure, the protrusion a moves into the recess b.
Since the clipper head 3 is detached from the clipper head 3, the clipper head portion 3 can be rotated. Simultaneously with the pressing operation of the support shaft 2b, the lock plate 19 is pushed by the operating portion 19b by the pressing piece 24 of the support shaft 2b and swings about the shaft 20, and the operating portion 19a comes off from the cutout portion 17a. The plow comb 14 is now moved backward by the force of the spring 18 until the rear end 14c hits the stopper part 25 of the slide plate 17. This retraction causes the clearance teeth 14a to retract further rearward from the original retracted position within the gap between the upper wall 3a of the clipper head portion 3 and the cutting edge of the movable blade 10. Therefore, the clipper head section 3 is rotated upward by a predetermined angle around the support shafts 2a, 2a, and the rear end 3b of the upper wall 3a of the clipper head section 3 is located near the middle of the handle 14b of the plowing comb 14. Even if it is bent and deformed to
4a does not protrude forward from the upper wall 3a of the clipper head part 3, and even when the clipper head part 3 is placed in an upward position, a round cut can be made without being hindered by the plow teeth 14a. Incidentally, when mowing with the clipper head section 3 in the upward position, slide the operation knob 23 in the same manner as when the clipper head section 3 is in a straight line position to move the plow-cutting comb 14. This can be done by making it stick out.

When returning the plow comb 14 from the shortened and retracted state shown in FIG. 5 to the original extended and retracted state, first push the lock button 27 of the operation knob 23 as shown in FIG. 6 to engage the lock spring 26 with the main body case 1. After releasing the operation knob 23, the operation knob 23 is moved backward to the second retreat position D, and only the slide plate 17 integrated with the knob 23 is moved back to engage the action part 19a of the lock plate 19 with the notch 17a. The plow-cutting comb 14, whose backward movement is restricted from abutting, returns to the extended state in which it is separated from the slide plate 17 by a stroke S. Next, when the operation knob 23 is returned to the normal first retracted position A, the slide plate 17 and the plow comb 14 are pushed forward, and the plow teeth 14a close the gap between the upper wall 3a of the clipper head 3 and the movable blade 10. Return to the original exit position inside.

According to the above embodiment, the clipper head 3 cannot be rotated upward unless the support shaft 2b is pressed, and the clipper head 3 can be rotated upward at the same time as the support shaft 2b is pressed. In addition, the slide plate 17 and the lock plate 19
The plow-cutting comb 14 can be automatically moved further back from its original retreating position via the comb 1, making it very convenient to use. However, the present invention is not limited to this. For example, the plow comb 14 is
Instead of allowing the protruding operation to be performed in two stages: the protruding position (large gap position) and the second protruding position (small gap position), it may be possible to operate the protrusion in only one stage, the first protruding position or the second protruding position.

As explained above, according to this invention, the clipper head part 3 equipped with the movable blade 10 and the fixed blade 11 is attached to the main body case 1 so as to be rotatable around the support shafts 2a and 2b. A plow-cutting comb 14 which can be bent and deformed from 3 to the main body case 1 is disposed so as to be movable in the front-rear direction.
An operating knob 23 is attached for operating the comb 4a to switch between a position in which it protrudes from the front end of the hair clipper head 3 and a position in which it retracts. The plow comb 14 is deformed and protrudes by the length that moves.
It is equipped with an adjustment means for correcting the protrusion length by retracting the protrusion. Therefore, even if the clipper head section 3 is rotated to an upward position, the plow-cutting comb 1
Since the problem of the plow teeth 14a of the plow comb 14 protruding forward from the clipper head 3 can be solved, it is not obstructed by the plow teeth 14b of the plow comb 14 even when the clipper head 3 is rotated upward. You can perform a round cut without any hassle. Furthermore, plow cutting comb 1
4 is arranged from the clipper head part 3 to the main body case 1, so that it can be moved in and out with the hand holding the main body case 1, and has the advantage of being easy to use.
