Description

[Detailed description of the invention] The present invention relates to an electric razor with a trimmer mechanism.

Conventionally, this type of electric razor took a considerable amount of time to cut curly or long hair using only a net blade, and was not easy to use.

Therefore, the trimmer mechanism can be used in conjunction with the trimmer mechanism to reduce curly hair.
It has been proposed to perform shaving with a 5-net blade while cutting long hair, but conventional products such as JP-A-51-8060 are equipped with a trimmer mechanism and a net blade, and only a net blade is used. It has drawbacks such as the trimmer mechanism being a hindrance when it is desired to be used.

The present invention eliminates the above-mentioned drawbacks, and provides a trimmer mechanism that allows the trimmer mechanism to be sufficiently close to the net blade when the trimmer mechanism is used in combination, while appropriately separating the trimmer mechanism from the net blade when the trimmer mechanism is not used in combination. The purpose is to provide an electric razor with an electric razor.

The present invention will be explained below along with the drawings.

In FIGS. 1 to 5, 1 is a body in which a battery 2 and a motor 3 are built, and an outer cutter frame 5 holding a net cutter, that is, an outer cutter 4, is attached.

Reference numeral 6 denotes an inner cutter that is slidably installed inside the outer cutter 4, and as is well known, is pressed against the outer cutter 4 by a push-up spring 7, and is driven by the eccentric body 8 and driven by the output of the motor 3 inside the body 1. It is reciprocated via the body 9.

1'' is a trimmer mechanism attached to one side of the outer cutter frame 5 so as to be inclined toward the outer cutter 4 as a whole, and includes a pair of guide plates 11, 11, a moving plate 12, and a trimmer base 13. There is.

The guide plate IL11 is formed to match the inclined surfaces 14, 14 and the step portions 15, 15 of the outer cutter frame 5, and includes a fixing pin that can be fitted into fixing holes 16, 17 drilled in the outer cutter frame 5 and fixed. 18 and 19 are installed protrudingly.

Further, the guide plate N1.11 is provided with recesses 20, 20 so as to form a guide channel together with the inclined surface 14.14 of the outer cutter frame 5.

Furthermore, each recess 20.20 has two engaging portions 21°2.
2 is formed.

On the other hand, the moving plate 12 has a dog notch 23 in a concave shape, and recesses 25.25 whose inner bottom surfaces are arcuate are formed on both sides 24.24, and the outer cutter frame is formed on the end surfaces of both sides 24 and 24. 5 inclined surfaces 15, 15 and guide plates 11, 11
An elastic guide 26.26 extends which can be inserted into the guide channel formed by the recess 20.20.

The elastic guides 26.26 are provided so that at least their tips are elastic, and the protrusions 27.27 that bulge outward at the tips fit into the recesses 20.27 of the guide plates 11,11.
It is possible to engage into engagement portions 21 and 22 formed in 20.

Further, the trimmer base 13 is attached to both sides 2 of the movable plate 12.
4. comprises a lower part 28 which can be located between said lower part 2
8 has a horizontally protruding rotating shaft 30.30 which is inserted through shaft holes 29, 29 provided on both sides 24.24 and is pivotally supported.

Further, a restraining protrusion 32 is protruded from both end surfaces of the upper part 31 of the trimmer base 13, and the restraining protrusion 32 includes the inclined surface 14.14 of the outer cutter frame 5 and the recess 20 of the guide plate NL11. , 20.

In this case, in order to facilitate the introduction of the restraining protrusion 32 into the guide channel, it is preferred that the upper end walls of the recesses 20, 20 be provided with inclined surfaces.

In addition, a fixed blade 33 having a blade portion at the tip is fixed to the trimmer base 13, and a movable blade that can slide relative to the fixed blade 33 is provided in a sliding recess 34 formed on the inner surface. 35
is accommodated.

A driven arm 37 that can be locked with the trimmer drive frame 36 of the drive body 9 extends from the lower edge of the movable blade 35;
Also, a guide pin 38.3 protruding from the sliding recess 34
A guide hole 39° 39 is provided in which the guide hole 8 is fitted.

Reference numeral 40 denotes a spring holder, and a presser spring 41, 41 is disposed between the fixed blade 33 and the movable blade 35 so as to press the movable blade 35 against the fixed blade 33, and protrudes from both ends of the trimmer base 13 at both ends. An engaging portion 43 fixed to the fixed protrusions 42, 42,
43 has been extended.

44 is wound around one rotating shaft 30 of the trimmer base 13, with one end attached to the movable plate 12 and the other end attached to the trimmer base 13.
The torsion spring engaged with the trimmer base 13 functions to rotate and project the trimmer base 13 with respect to the movable plate 12.

45 is a switch plate slidably attached to the body 1;
The movable plate 12 is provided so as to be pushed up, and the motor 3 is configured to be energized during upward movement.

Further, the operation of the present invention will be explained in detail.

In the state shown in FIG. 2, the switch plate 45 is in the downward movement position, and the projections 27. 1, and the driven arm 37 of the movable blade 35 is engaged in the trimmer drive frame 3 of the drive body 9.
6, and the trimmer mechanism 1'' is not driven.

On the other hand, if the switch plate 45 is pushed up from the state shown in FIG. 2 as shown in FIG. 4, the elastic guides 26.2 of the moving plate 12
6 moves obliquely upward within the guide channel formed by the inclined surface 14° 14 of the outer cutter frame 5 and the recess 20° 20 of the guide plate 11. ” The entire body moves diagonally upward, that is, toward one side of the outer cutter 4, and the protrusion 27.27 of the elastic guide 26.26 moves toward the guide plate 11.1.
When the movable blade 35 enters the second engaging portion 22 formed in the recess 20. do.

Therefore, the trimmer mechanism 1'' is applied to the skin 46 together with the outer blade 4, and the trimmer mechanism 10 smoothly cuts the curly hair 47, etc.
The outer blade 4 can shave the beard.

In addition, if the switch plate 45 is further pushed up from the state shown in FIG. 4 as shown in FIG. 14.14 and recess 20.2 of guide plate IL11
A torsion spring 44 deviates from the guide channel formed by 0 and is wound around one rotating shaft 30 of the trimmer base 13.
As a result, it is rotated about the rotating shaft 30, 30 as a fulcrum and is caused to protrude.

At this time as well, the driven arm 37 of the movable blade 35 is provided so as to engage with the trimmer 5 drive rod 36 of the 1 drive body 9, so the trimmer mechanism 1-0 can be used alone to perform the cutting operation. can.

Note that by rotating the trimmer base 13 in the opposite direction from the state shown in FIG. 5 and pushing it down slightly to re-engage the holding projection 32 into the guide channel, the state shown in FIG. 4 can be returned to the state shown in FIG. By pushing down the base 13, the state shown in FIG. 3 can be achieved.

According to the electric razor with a trimmer mechanism of the present invention configured as described above, the net blade, that is, the outer blade or the trimmer mechanism can be used independently without interfering with each other, and the trimmer mechanism can be used as desired. It can be reliably used in conjunction with shaving curly hair, etc., and achieves remarkable effects such as extremely convenient usability.
