Abstract

PROBLEM TO BE SOLVED: To provide an electric razor the portability of which is favorable, and at the same time, which is hard to break. SOLUTION: This electric razor comprises a trimmer blade 2 equipped with a fixed blade and a movable blade which performs a reciprocating movement and slides to the fixed blade, and a main body 1 in which a driving member to drive the trimmer blade 2 is housed. The trimmer blade 2 is made turnable based on the main body 1 in a plane including the sliding face between the movable blade and the fixed blade, or a plane which is close to such a plane, and by the turning, a state wherein the trimmer blade 2 is housed in the main body and a state wherein the trimmer blade 2 protrudes from the main body can be switched. By housing the trimmer blade 2 in the main body 1, the electric razor is made compact and excellent in portability, and at the same time, a dropping impact can be prevented from being applied to the trimmer blade 2. The connection of a power transmission between the driving member on the main body 1 side and the movable blade on the trimmer blade 2 side, is made disengageable, and the folding structure is simplified compared with a case wherein the connected state is always kept.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric razor, and more particularly to an electric razor having a blade portion formed of a trimmer blade.

[0002]

2. Description of the Related Art There has been provided an electric shaver having a trimmer blade extending from one end of a rod-shaped main body as an electric razor for trimming facial hair or long hair (whisker). In addition, since this type of electric shaver is desired to be excellent in portability, a thin type is generally provided.

[0003]

However, in the case of a slender shape, if it is dropped or subjected to an impact, it may be broken and the trimmer blade is often deformed. The present invention has been made in view of such a point, and an object of the present invention is to provide an electric shaver which has good portability and is not easily broken.

[0004]

SUMMARY OF THE INVENTION The present invention provides a trimmer blade having a fixed blade and a movable blade which reciprocates and slides on the fixed blade, and a main body containing a driving member for driving the trimmer blade. The trimmer blade is rotatable with respect to the main body in a plane including or near a sliding surface between the movable blade and the fixed blade, and the trimmer blade is housed in the main body by the rotation. And the power transmission between the drive member on the main body side and the movable blade on the trimmer blade side is freely switchable. . By storing the trimmer blade in the main body, the trimmer blade can be made compact and excellent in portability, and at the same time, a drop impact is not applied to the trimmer blade. Further, since the drive system can be connected and disconnected freely, the folding structure can be simplified as compared with the case where the connection state is always maintained.

It is preferable that a power transmission portion between the driving member on the main body side and the movable blade on the trimmer blade side be connected and disconnected by rotation of the trimmer blade with respect to the main body. It is preferable to provide a switch that turns on and off in conjunction with the rotation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described. This electric razor is such that a trimmer blade 2 can be folded and stored in a main body 1, and the main body 1 is shown in FIG. As shown, body 10 and middle plate 11,
The cover 12 is formed as a stack,
A battery 14 as a power supply and a motor 15 are housed in a body 10 whose side opening is closed by the middle plate 11. An eccentric pin 16 is attached to the output shaft of the motor 15,
The eccentric pin 16 passes through the middle plate 11 and is located in a space between the middle plate 11 and the cover 12. In the figure, reference numeral 13 denotes a battery compartment cover which is detachable from the body 10.

[0007] Between the cover 12 and the middle plate 11,
A space for accommodating the trimmer blade 2 is formed, and a support shaft 1 is provided on an opposing surface of the cover 12 and the intermediate plate 11, respectively.
7, 17 are protrudingly provided. In the figure, reference numeral 18 denotes a hook provided integrally with the middle plate 11 and engaged with the body 10, and 19 denotes an assembly screw. The trimmer blade 2 is a base plate 2 made of synthetic resin.
0, a fixed blade 21 fixed to the base plate 20, a movable blade 22 slidable with respect to the base plate 20, a cam plate 23 fixed to the movable blade 22, and the like. The base plate 20 is provided with a bearing hole 25, a knob 26, and a pressing projection 27.

[0008] The trimmer blade 2 has a support shaft 17 formed by inserting support shafts 17 formed in the cover 12 and the intermediate plate 11 into bearing holes 25 provided in the base plate 20.
Is rotatable around the center, and when rotated in one direction, it is stored in the storage space between the cover 12 and the middle plate 11. When rotated in the other direction, the trimmer blade 2 projects from one end in the longitudinal direction of the main body 1 in the same direction.

Here, the support shaft 17 is provided at a position shifted from the eccentric pin 16 attached to the output shaft of the motor 15, and when the trimmer blade 2 projects from the main body 1, the cam plate on the trimmer blade 2 23 cam grooves 24
The eccentric pin 16 enters the inside, and the cam plate 23 is moved as the eccentric pin 16 rotates eccentrically by operating the motor 15.
Makes the movable blade 22 reciprocate, but the trimmer blade 2
If the motor 15 rotates, the cam plate 23 and the movable blade 22 do not operate even if the motor 15 rotates.

In the illustrated example, the motor 1
5, the anode terminal plate 32 that contacts the anode of the battery 14, the cathode terminal plate 33 attached to the battery compartment cover 13, and the cathode terminal plate 33 of the motor 15 and the cathode terminal plate 33. A circuit is formed by the connection metal fittings 34 for connecting between them, and the motor 15 is energized by ensuring conduction between the anode metal fittings 31 and the anode terminal plate 32, but is arranged in the body 10. Anode fitting 3
1 and the anode terminal plate 32 are formed by the long holes 3 formed in the middle plate 11.
The contact portions 31a and 32a, which are located in the space between the cover 12 and the middle plate 11 through 6, 37, respectively, are provided, and both contact portions 31a and 32a are normally in a non-contact state. For this reason, the motor 15 is turned off, but when the cam plate 23 and the eccentric pin 16 are engaged by rotating the trimmer blade 2 to protrude from the main body 1, the pressing projection provided on the base plate 20. 27 presses the contact portion 32a of the anode terminal plate 32 to make contact with the contact portion 31a, so that the motor 15 is energized.

[0011]

As described above, in the present invention, the trimmer blade is rotatable with respect to the main body in a plane including a sliding surface between the movable blade and the fixed blade or a plane close to the plane. Since it is possible to switch between the state stored in the main body and the state protruding from the main body, it is possible to make it compact and excellent in portability by storing the trimmer blade in the main body when not in use. In addition, since the drop impact is not applied to the trimmer blade, breakage of the trimmer blade can be prevented. In addition, since the power transmission between the driving member on the main body side and the movable blade on the trimmer blade side can be freely connected and disconnected, a complicated configuration for constantly maintaining the power transmission state is not required, and the folding structure has a folding structure. Can be obtained easily.

The power transmission portion between the driving member on the main body side and the movable blade on the trimmer blade side is connected and disconnected by the rotation of the trimmer blade with respect to the main body in order to simplify the structure. Good results can be obtained. Also, if a switch that turns on and off in conjunction with the rotation of the trimmer blade with respect to the main body is provided, it can be turned on when in use and off when not in use without separately performing on / off operation, so that convenience is improved. .
