Description

[Detailed description of the invention] [Industrial application field] The present invention is designed to prevent the cover covering the outer blade from being lost during use of the razor or from being damaged due to falling when removed from the outer blade case. This invention relates to a vibrating razor that is supported by an outer cutter case even during use.

[Prior art] Conventionally, for example, "Japanese Patent Publication No. 10713/1973"
A vibrating razor is disclosed in which an outer cutter case to which an outer cutter is attached is provided with a shutter-like cover that is movable from a use position where the outer cutter is exposed to a storage position where the outer cutter is covered.

This cover is interposed between the left and right side walls of the outer cutter case, and is movably supported with respect to the outer cutter case by fitting both side edges of the cover into guide grooves provided in the side walls. The guide groove that guides the movement of the cover is provided outside the outer blade so as to follow the upper curved shape of the side wall, and when the cover is moved to a position where it covers the outer blade,
This cover is interposed between the side walls of the outer cutter case so as to be substantially flush with each other.

[Problem to be solved by the invention] However, in the case of this configuration, since the guide groove for guiding the cover is provided outside the outer blade,
When the cover is opened to expose the outer cutter, the upper circumferential surface of the side wall protrudes outward more than the outer surface of the outer cutter.

For this reason, when using the razor, the side wall may come into contact with the face, and this side wall becomes a hindrance, making it difficult to use.

The present invention was developed based on these circumstances, and aims to provide a vibrating razor that is easy to use without the outer blade case getting in the way while the razor is in use.

[Means for Solving the Problems] Therefore, in the present invention, the outer cutter case to which the outer cutter is attached is formed by integrally connecting a number of mutually parallel thick-walled parts with a thin-walled part, and the thin-walled part A flat plate-shaped outer cutter cover that is flexibly deformed in the outer cutter case is provided on the outer cutter case, and both edges of the outer cutter cover are fitted and supported, and the outer cutter cover is removed from the use position where the outer cutter is exposed. In a vibrating razor equipped with a guide groove that movably guides the blade to a storage position where the blade is covered, the outer cutter cover is spaced apart from the outer surface of the outer cutter so as to be continuous with both edges that fit into the guide groove. A pair of rising step portions rising in the direction of It is characterized in that it is attached to the above-mentioned outer cutter case in the state of being

[Function] According to this configuration, the cover portion of the outer cutter cover is
Since it is spaced apart from the outer surface of the outer cutter by the height of the rising step, the outer cutter can be moved toward the outer cutter cover without being restricted by the position of the guide groove on the outer cutter cover. The outer surface and the peripheral surface of the outer cutter case can be provided substantially flush. Therefore, the outer cutter case can be prevented from protruding on both sides of the outer cutter, and the outer cutter case will not get in the way while the razor is being used.

[Example] The present invention will be described below based on an example shown in the drawings.

Reference numeral 11 in the figure is a razor body, and a reciprocating vibration generator (not shown) is housed inside the razor body. At the top of the razor body 11 is an outer blade case 13.
is attached removably. The outer cutter case 13 is made of a molded product made of light metal or the like, and as shown in FIG.
It is formed into a frame shape from a front wall 16 and a rear wall 17 that connect the front wall 16 and the rear wall 17. The upper parts of the side walls 14 and 15 protrude upwards from the front wall 16 and the rear wall 17 and are curved in an arc shape.
The outer cutter 12 is attached between the upper portions of the blades 15.

It goes without saying that an inner cutter (not shown) that is reciprocated by the reciprocating vibration generator is in sliding contact with the inner surface of the outer cutter 12.

Furthermore, guide grooves 19 are provided on the opposing inner surfaces of the left and right side walls 14 and 15, respectively. The guide groove 19 is configured to movably guide an outer cutter cover, which will be described later, from a use position where the outer cutter 12 is exposed to a storage position where the outer cutter 12 is covered. A case is shown in which an inverted J-shape is formed from an arcuate portion 19a that follows the shape and a vertical portion 19b that continues to one end of the arcuate portion 19a.

In the case of this embodiment, the vertical portion 19b of the guide groove 19 is formed inside the rear wall 17.

Further, reference numeral 20 in FIG. 4 indicates outer cutter locking grooves formed on the inner surfaces of the side walls 14 and 15, respectively, into which the attachment portion 12a of the outer cutter 12 is removably inserted and locked. has been done.

Incidentally, the outer cutter case 13 is movably provided with an outer cutter cover 21 that exposes or covers the outer cutter 12. The outer blade cover 21 is made of synthetic resin and has a large number of thick parts 2 that are parallel to each other.
2 are integrally connected by a thin wall portion 23,
At least the thin-walled portion 23 is configured to be flexible and deformable. The outer cutter cover 21 has a pair of left and right edges 21a and 21b fitted into and supported by the guide groove 19, and is movably attached to the outer cutter case 13.

Furthermore, both edges 21a and 21b of the outer blade cover 21
A knob 24 is integrally provided on at least one side of the side wall 14 on the side corresponding to the knob 24.
A slot 25 is formed in the guide groove 19 to communicate with the vertical portion 19b of the guide groove 19. For this reason, the knob 24 of the outer cutter cover 21 penetrates the side wall 14 of the outer cutter case 13 and is guided outward, and if the knob 24 is slid along the slot 25, the outer cutter cover 21
1 is moved from a storage position where the outer cutter 12 is covered to a use position where the outer cutter 12 is exposed.

On the other hand, the outer cutter cover 21 has its guide groove 19
A pair of rising step portions 29 that rise in a direction away from the outer surface of the outer cutter 12 are continuous with the left and right edges 21a and 21b that fit into the outer cutter 12. cover part 30 that covers the outer surface of
It is equipped with the following. As shown in FIG.
The tip of the blade fits into the gap 31 between the blade and the blade, and its tip protrudes above the side walls 14 and 15 and the outer blade 12. Therefore, when the outer cutter cover 21 is moved to the storage position, the cover portion 30 of the outer cutter cover 21 is located above the side walls 14 and 15, that is, the upper peripheral surface of the outer cutter case 13 and the outer cutter 12. It is supported by this outer cutter case 13 in a protruding state.

When the vibrating razor with such a configuration is not in use, as shown in Figs. 1 and 5,
The outer cutter cover 21 is moved to the arcuate portion 19a of the guide groove 19 and covers the outer surface of the outer cutter 12,
At this time, the knob 24 of the outer cutter cover 21 is located at the upper end of the slot 25.

To use the vibrating razor from this state,
First, the knob 24 is pushed down to move the outer cutter cover 21 to the vertical portion 19b of the guide groove 19 as shown in FIG. As a result, the outer cutter cover 21 separates from the outer surface of the outer cutter 12 and the outer cutter 12 is exposed, so that the reciprocating vibration generator can be operated.
In this case, the outer cutter cover 21 is arranged so as to overlap the rear wall 17 of the outer cutter case 13, so the outer cutter cover 21 does not get in the way of shaving.

Further, after using the razor, the outer cutter cover 21 may be moved to the arcuate portion 19a of the guide groove 19 via the knob 24, and the outer cutter 12 may be covered with the cover portion 30. Such movement of the outer blade cover 21 is as follows:
Although the guide groove 19 has an inverted J shape,
In addition, the strength of the outer cutter cover 21 is determined by its thick portion 22.
Despite the fact that this outer blade cover 2
1 has flexibility as a whole, so this can be easily done.

By the way, in the above configuration, the outer blade cover 2
1, both edges 21a, 2 that fit into the guide groove 19
1b, a rising step portion 29 is formed that rises in a direction away from the outer surface of the outer cutter 12, and a cover portion 30 that covers the outer surface of the outer cutter 12 by the height of this rising step portion 29 is attached to the outer cutter case. 16, the outer cutter 12 is not restricted to the position of the guide groove 19, and the outer cutter 12 is not restricted to the position of the guide groove 19.
15, and can be provided substantially flush with the upper circumferential surfaces of the side walls 14, 15.

For this reason, the side walls 14, 1 on both the left and right sides of the outer cutter 12
5 does not protrude beyond this outer cutter 12, so that the side walls 14, 15 and the outer cutter case 13
This has the advantage that it does not get in the way when shaving, making it easier to use.

[Effect of the invention] According to the invention detailed above, the outer cutter and the outer cutter case are substantially flush with each other, so that the peripheral surface of the outer cutter case does not protrude on both sides of the outer cutter as in the conventional case. This prevents the outer blade case from hitting your face while using the razor. Therefore, the outer blade case does not get in the way while the razor is being used, and there are practical effects such as improved usability.
