Description

[Detailed description of the invention] The present invention relates to the structure of the cutting unit in an electric shaver. It lies flat on a surface, and when in use, it rotates 90 degrees and stands up to protrude horizontally, and is operated using an external operating member.

In this type of model, the present invention allows the edge unit to be reliably held in both the stored state where it lies down and the operating state where it is raised horizontally.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
FIG. 1 shows a vibrating electric razor. A blade frame head 2 on which a shaving blade 1 is mounted is removably attached to the upper surface of the main case 3, and a rectangular opening 4 is provided in the upper part of the main case 3. In this opening 4, a special unit 5 is rotatably supported by support shafts 6, 6 provided on the longitudinal side thereof.

7 is the heir of the drive switch for the shaving blade 1 and the shaving unit 5; 8 is the position where the shaving unit 5 is housed as shown in Figure 3; 4. This is an operating knob that is operated to the operating position shown in the figures.

In the edge resetting unit 5, a edge cutting blade 12 consisting of a fixed blade 10 and a movable blade 11 is attached to a support body 9, and a movable blade 1
A driving member 13 is engaged with the blade 1, and a support fitting 14 is provided to prevent the driving member 13 and the blades 10, 11 from falling.

A one-shaped notch 15 is formed at the rear end of both side walls 9°9 of the support body 9.

Reference numeral 16 designates an operating lever that moves up and down in succession with the operating knob 8, and the claw portion 17 at the tip engages with the notch 15 of the edge-sliding unit 5 to move the edge-sliding unit 5 into the third position. It is freely rotated 90 degrees between the storage position and the operating position as shown in FIGS.

The operating rod 16 is supported between the wall surface 18 of the main body case and a supporting piece 20 provided on a part of a wall plate body 19 made of synthetic resin, which is separately provided on the back side of the main body case wall surface 18, so that it can be smoothly guided up and down. ing.

The wall plate body 19 is fixed on the electric motor support plate 21 inside the main body case 3, and the support shaft 6 of the edge sliding unit 5 is attached to both ends.
, 6 from the rear surface, and only the front half of the support shaft 6.6 fits into a semicircular groove (not shown) formed on the edge of the rectangular opening 4. The support shafts 6, 6, which have become unstable due to this, are stably held.

The key point is to hold the unit 5 in each state, which is rotated to the stored and operating state by the operating rod 16 in this way.
A holding protrusion 23 provided on the back side of the rear unit 5;
An elastic holding piece 24 on the wall board 19 and an elastic holding piece 26 horizontally protruding from the back side of the upper wall 25 of the rectangular opening 4
It is.

That is, the engagement protrusion 2 is also provided at the tip of each of the elastic holding pieces 24 and 26.
7 and 28, the engaging protrusion 27 is used to hold the edge sliding unit 5 when it is stored, and the engaging protrusion 28 is used to hold the edge sliding unit 5 when it is activated. Part 27
, 28 are fitted with and fixed to the holding protrusion 23.

Therefore, when the edge reuniting unit 5 is lying down as shown in FIG. are mated,
This stored state is reliably maintained.

On the other hand, when the operating lever 16 is lowered by the operating knob 8 from this state, the claw portion 17 causes the rear unit 5 to begin to rotate upward about the supporting shafts 6, 6.

During this process, the retaining protrusion 23 is separated from the engaging protrusion 27, and when it has completely rotated 90 degrees, the engaging protrusion of the elastic retaining piece 24 on the wall plate 19 side is now turned as shown in FIG. The holding protrusion 23 is fitted into the holding protrusion 28 to ensure that the edge cutting blade 12 is held in the horizontally protruding operating state.

Of course, at this time, although not shown, the rear end of the drive member 13 of the edge cutting blade 12 engages with a suitable drive member in the main body case 3 and is reciprocated, causing the edge cutting blade 12 to vibrate.

As described above, according to the present invention, the unit is rotatably supported on its longitudinal side as a fulcrum, and the storage state in which the unit is flush with the case surface by the operation member, and It is designed to be rotated upwards and the operating state in which the cutting blade protrudes horizontally, respectively, and in order to ensure that each state is held and fixed, the The holding protrusions provided on the back surface are configured to fit with the engaging protrusions of the elastic holding pieces provided inside the main body case.

Therefore, it is extremely simple as a holding mechanism for the reunit, and can be held stably, which has great practical effects.
