Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a trimmer protection device for an electric shaver that protects the cutting edge of a trimmer portion of an electric shaver.

For conventional electric razors with a trimmer, when using the finishing blade without a trimmer, it is necessary to protect the trimmer and to use the finishing blade safely so that the trimmer does not cut your fingertips or skin. For example, a trimmer was installed in the body of an electric shaver so that it could be moved in and out, and a cap could be attached to and removed from the trimmer.

However, the former method has a complicated structure, which poses problems in terms of ease of assembly and cost, and the latter method is troublesome to attach and remove the cap, and it is easy to damage the cutting edge of the trimmer by attaching and detaching the cap. It had drawbacks such as being easy to lose.

Further, in the Japanese Utility Model Application Publication No. 49-65494 shown in FIG. 5, the guide comb blades 30 which are slidably disposed on the electric shaver body are placed sufficiently close to the trimmer part 2, but the guide comb blades 30 are at the cutting edge. It is not located in front of the blade and covers the cutting edge.

Therefore, even if the guide comb blade 30 is brought close enough to the trimmer portion 2, the blade tip will be exposed to the outside, and the blade tip will injure fingers or skin.

Also, if the cutting edge is not covered by the guide comb blade 30 (if a sharp object collides with it from the front, the guide comb blade 3
It does not hit zero and collides directly with the cutting edge, so the cutting edge cannot be completely protected.

The present invention was invented in view of the above points, and its purpose is to prevent the trimmer from damaging the skin, fingertips, hands, etc. when the trimmer is not used, and to protect the trimmer. To provide electric shaver trimmer protection device.

The electric shaver trimmer protect device of the present invention includes a protector 3 that can freely slide along the lower side of the electric shaver body 1, which has a finishing blade part 6 at the upper end and a trimmer part 2 at the upper side. Provided, the protector 3
The guide comb teeth 18 at the upper end allow the cutting edge of the trimmer part 2 to be covered and exposed, and the covered state of the cutting edge of the trimmer part 2 is arranged in front of and close to the cutting edge of the trimmer part 2. The cutting edge of the trimmer part is configured to be slightly recessed from the line connecting the tip of the guide comb teeth 18 and the outer surface of the finishing blade part 6, and with this configuration, the above purpose can be achieved. is a distant relative.

The present invention will be explained in detail below with reference to Examples.

As shown in FIG. 1, a finishing blade section 6 consisting of an outer cutter 4 and an inner cutter 5 is provided at the upper end of the electric shaver main body 1.
A trimmer section 2 consisting of a fixed blade 7 and a movable blade 8 is provided on the upper side, and the lower end of the electric shaver body 1 is connected to the upper end of a housing (not shown) in which a drive device is housed. The finishing blade section 6 and trimmer section 2 can be driven simultaneously or selectively by switching.

In the embodiment shown in the attached drawings, the inner cutter 5 of the finishing cutter 6 and the movable cutter 8 of the trimmer section 2 are simultaneously driven back and forth, and the spindle 9, which is rotationally driven by a motor, An eccentric drive shaft 10 is erected at the upper end, and the eccentric rotation of the eccentric drive shaft 10 drives the drive rod 1 through the roller 11.
2 is reciprocally driven, and an inner cutter 5 connected to this drive rod 12.
and the movable blade 8 are driven at the same time.

In the figure, 13 is a bearing for the spindle 9.

The electric shaver main body 1 has an open upper end, and as shown in FIG. 3, a peripheral wall 14 is provided with through holes to form a plurality of locking recesses 15. A cutout portion 16.16 is provided directly above the portion 15.

The protector 3 uses a comb, and has comb teeth 18.18 protruding forward and upward from the upper end of the board 1T, and a plurality of mounting legs 19.1 on the back side of the board IT.
9 is provided in a protruding manner, and the entire body is integrally formed of plastic or any other elastic material.

The mounting leg 19.19 is formed into a downward L-shape as shown in FIG. 3, and is provided with a lower end protrusion 2020 that projects toward the back surface of the substrate 1T at the lower end of the mounting leg 19.19.

When attaching the protector 3 to the electric shaver main body 1, the lower end protrusions 20, 20 of the attachment leg 1919 are engaged with the notches 16, 16, and when the protector 3 is pushed downward, the attachment leg 19 resists the spring elasticity. , 19 are expanded in the direction of being pulled away from the substrate 17, and the lower end protrusions 20, 20 are fitted into the locking recesses 15°15.

Here, the protector 3 is attached to the side of the electric shaver main body 1 below the trimmer part 2 so as to be able to slide up and down, and when the lower end protrusion 20 is fitted into the locking recess 15, the protector 3 is attached. At the uppermost position, the tips of the guide comb teeth 18, 18, . . . are located in front of the trimmer portion 2 as shown in FIG.

Also, push down the mounting leg as shown in Figure 2 to remove the lower end protrusion 20 from the locking recess 15, and then remove the guide comb teeth 18, 18...
... can be positioned below the trimmer section 2 to expose the cutting edge of the trimmer section 2.

22 in the figure is a nameplate attached to the front of the protector 3.

In the present invention, when the finishing blade part 6 is used without using the trimmer part 2, the protector 3 is moved upward and locked as shown in FIG. In this case, as shown in FIG. A line connecting the outer surface of the finishing blade part 6 (the first
The cutting edge of the trimmer section 2 is located slightly recessed from the point (shown by line A-A in the figure), so that hair can be shaved by bringing the electric razor body 1 and guide comb teeth 18 into contact with the skin. This prevents the cutting edge of the trimmer section 2 from being pressed strongly against the skin.

On the other hand, when using the trimmer section 2 without using the finishing blade section 6, lower the protector 3 downward to expose the cutting edge of the trimmer section 2 as shown in Figure 4, and adjust the trimmer section 2 according to the degree of exposure.
For example, you can shave the hair on your armpits, hands and feet, etc.

In this case, since a comb is used as the protector 3, the comb used in conjunction with the trimmer section 2 can function as a protector as is, and there is no need to use a separate member exclusively for the protector, reducing the number of parts and reducing costs. Moreover, the protector can be used as a comb for guiding hair to a normal trimmer part without any problems.

In the present invention, an electric shaver body having a finishing blade part at the upper end and a trimmer part at the upper side part is provided with a protector which can freely slide along the lower side part of the electric shaver body, and a guide comb at the upper end of the protector. The tip of the guide comb tooth and the finishing blade are arranged so that the cutting edge of the trimmer part can be covered and exposed by the teeth, and the covered state of the cutting edge of the trimmer part is in front of the cutting edge of the trimmer part and close to the cutting edge of the trimmer part. The cutting edge of the trimmer section is configured so that it is slightly recessed from the line connecting it to the outer surface of the trimmer section, so when the trimmer section is not in use, the protector can be moved to cover the cutting edge of the trimmer section with the tip of the protector for finishing. Even when the blade part is in use, it can be stopped or the cutting edge of the trimmer part in the driving state can prevent the cutting edge of the trimmer part from injuring fingers or skin, improving safety and preventing damage to the cutting edge of the trimmer part. This has the advantage that the cutting edge of the trimmer section is coated with the tips of the guide comb teeth disposed in front of and close to the cutting edge of the trimmer section and the finishing edge section. The blade edge of the trimmer part is configured to be slightly recessed from the line connecting it to the outer surface of the hair, so the blade edge of the trimmer part does not press strongly against the skin when shaving hair, preventing damage caused by the trimmer part to the skin. It is preventable.

Further, when the trimmer section is used, the protector is lowered to expose the cutting edge of the trimmer section, which has the advantage that the trimmer section can be used for edge cutting without the protector becoming a hindrance.

Therefore, by simply sliding the protector along the electric shaver body, it is possible to easily change the coating and exposure of the cutting edge of the trimmer section, and the trimmer section can be moved in and out of the electric shaver body as in the past. Since it is not necessary, the structure is simple and can be provided at low cost. Also, since the protector is attached to the electric shaver body, there is no chance of it falling off and being lost. Furthermore, the protector does not touch the cutting edge of the trimmer section, so it can be damaged. There's no fear.

Further, when shaving hair using the trimmer section, the guide comb teeth shape and raise the hair so that it is easily introduced into the trimmer section and can be shaved short.
