Description

[Detailed description of the invention] This invention is an electric razor whose main case can be folded low for convenient storage and portability when not in use.The invention improves the arrangement of the mirror for viewing the shaving condition. It is something that

In this type of electric shaver, a lid body that covers and protects the blade body when not in use is rotatably connected to a main body case equipped with a blade body consisting of an outer cutter and an inner cutter, and a lid body that covers and protects the blade body when not in use. Japanese Patent Laid-Open No. 56-148377 discloses a configuration in which the lid is opened downward and forms a grip.
It is also disclosed that a mirror is fixed to the inner recessed part of the lid, and the mirror is exposed to the outside only when in use, so that the shaving condition can be seen.

However, the lid seen in the conventional example mentioned above is literally a lid member that covers and protects the blade when not in use, and the main body case itself cannot be folded compactly and can be placed stably on a desk in a standing position. However, the lid does not function as well. The mirror is also located at the part that covers the blade, i.e. at the lower end of the lid when it is unfolded, so when in use, the mirror tends to be hidden by the fingers that hold the lid, making it difficult to see, and the mirror coming into contact with the fingers. It's easy to get cloudy.

Therefore, the purpose of this invention is to have a main body case that can be folded compactly when not in use, making it convenient for storage, carrying, and stable placement on a desk in a standing position, while also allowing the main body case to be unfolded so that it is easy to grasp when in use. There is a way to get a switchable electric razor.

Another object of the present invention is to provide an electric shaver in which the mirror integrally attached to the main body case is hidden when not in use, and is exposed in an easy-to-see position when used in the unfolded state, and which is also effective in preventing fogging of the mirror. .

In order to achieve the above object, in the present invention, as shown in the figure, a main body case C includes an upper case 1 having an outer cutter 3 and an inner cutter 4 that slides thereon, and a lower case C rotatably connected to the lower part of the upper case 1. The lower case is switchable between an upright position in which the lower case 2 is at least substantially in a straight line with respect to the upper case 1 and a lying position in which the lower case 2 is folded forward and approximately perpendicular to the upper case 1; The front part of the upper circumferential surface 2b of the lower case 2 faces the lower end surface 1a of the upper case 1 and is hidden when the lower case 2 is in the lying position, but is exposed to the front when the lower case 2 is in the upright position. This requires that the mirror 17 be fixed.

Hereinafter, the details will be explained based on the drawings. FIGS. 1 to 5 illustrate an electric shaver according to the present invention, in which the main case C is an upper case 1.
and lower case 2.

The upper case 1 has an outer cutter 3 and an inner cutter 4 that slides on the outer cutter 3 on its front surface, and has a built-in motor 5 that drives the inner cutter 4. The lower case 2 houses a battery consisting of a main battery 6 and a sub-battery 7, a transformer 8, etc., and is separately provided with a removable plug blade 9 for charging. An operating knob 10 for an on/off switch for the main battery 6 and the sub battery 7 is attached to the outer surface of the upper case 1.

A lower case 2 is rotatably connected to the lower end of the upper case 1. Specifically, a pair of left and right joints 12, 12 are provided on the lower surface of the upper case 1 to protrude downward, and approximately the upper half of the lower case 2 is fitted between the two joints 12, 12. Pivot shafts 13, 13 protruding from the left and right end faces of the lower case 2 are rotatably connected to bearings 14, 14 recessed in the inner surfaces of the joints 12, 12. In such a case, the lower case 2 can be placed in an upright position (FIG. 2) extending along the downward extension of the upper case 1 with the pivot shaft 13 as the rotational fulcrum O, or in a forward facing position below the upper case 1 and substantially perpendicular to the upper case 1. It is possible to switch between the folded position (Fig. 3) and the lying position (Fig. 3). This pivot point O is set at a position offset downward by δ from the center line S of the outer cutter 3 of the upper case 1. Note that the joints 12, 12 are formed on the upper part of the lower case 2, and the joints 12, 12 are
The lower part of the upper case 1 may be fitted and supported in between.

On the pivot portions of the upper and lower cases 1 and 2, a projection 15 for adjusting rotation selectively engages with one of the recesses 16 and 16 provided at two positions, so that the lower case 2 can be placed in the above-mentioned upright posture and lying posture. Each is retained.

Thus, when the lower case 2 is in the lying position, the outer cutter 3 of the upper case 1 faces the lower end surface 1a of the upper case 1, but when the lower case 2 is in the upright position, the outer cutter 3 of the upper case 1 faces the lower end surface 1a of the upper case 1.
A mirror 17 is attached to the front part of the convexly curved upper circumferential surface 2b of the lower case 2 which is located below and projects toward the front, and is flush with the mirror 17 along the convexly curved surface. The mirror 17 may have a flat plate shape by forming the upper circumferential surface 2b into a planar shape.

In such a case, as shown in Figs. 3 and 5, move the lower case 2 roughly forward about the rotational fulcrum O.
When the body case C is turned 90 degrees and placed in a lying position, the vertical height of the entire main case C, which is the combination of the upper case 1 and the lower case 2, falls within the height dimension of the upper case 1 including the joint 12. Therefore, the entire razor can be folded compactly when not in use. In this folded state, the lower case 2 serves as a pedestal for the upper case 1 and can be stably placed thereon.

The mirror 17 is the lower end surface 1a of the upper case 1.
It is well protected from getting dirty or scratched when carried or stored in a folded state.

When in use, when the lower case 2 is rotated from the folded state to the standing position shown in FIGS. Outer blade 3 of upper case 1
The distance between the center line S and the rotation fulcrum O, and the rotation fulcrum O
and the distance between the lower end surface 2a of the lower case 2. This is larger than the case where the rotation support point O is set on the center line S of the outer cutter 3 by the amount of eccentricity δ of the rotation support point O from the outer cutter center line S.

When the lower case 2 is rotated upright, the mirror 17 is exposed to the front, located directly below the outer blade 3 of the upper case 1, as shown in FIG. This makes it easy to see the status.

FIG. 6 shows another embodiment of the present invention, in which the lower case 2 can be rotated backwards by more than 90 degrees with respect to the upper case 1.
can be stopped at any angle via a rotation moderation means, and at the same time, from the front side, a Different types of mirrors 17 towards the rear, namely a convex mirror 17a and a plane mirror 1
7b and a concave mirror 17c are attached in this order.
When using this method, move the lower case 2 to arrow A in Figure 6.
The plane mirror 17b and the concave mirror 17c are sequentially exposed as they are rotated by a predetermined angle in the direction, and can be used depending on the purpose of projection.

In this way, it is desirable that the mirror 17 be completely covered by the lower end surface 1a of the upper case 1 in the unused state shown in FIG. 3, but it may be partially exposed in this state.

Further, in the electric shaver of the present invention, the inner cutter 4 is not limited to a rotationally driven type, but may be a vibrating type, and the outer cutter 3 and the inner cutter 4 are arranged upwardly on the upper surface of the upper case 1. It may be in the form of Also,
In addition to driving the motor 5 with the battery 6 or 7, it may be driven using a commercial power source. In that case, the electrical cord will be stored in the lower case 2.

As explained above, in this design, the inner and outer blades 3,
The lower case 2 is rotatably connected to the upper case 1 with the upper case 1, and when in use, the lower case 2 is in an upright position with respect to the upper case 1 in almost a straight line with the upper case 1, increasing the grip length. I made it possible, so
Easy to hold and use. When not in use, the lower case 2 can be compactly folded into a forward lying position that is substantially perpendicular to the upper case 1, making it convenient to carry when traveling or the like.

In addition, in this folded state when not in use, the lower case 2 also serves as a pedestal for the upper case 1, allowing the entire electric shaver to be placed stably in a standing position on a desk or the like via the lower case 2. It will also happen.

Moreover, the mirror 1 is attached to the upper peripheral surface 2b of the lower case 2.
7 is fixed and the lower case 2 is in a lying position when not in use, the mirror 17 is attached to the lower end surface 1a of the upper case 1.
When the lower case 2 is in use with the lower case 2 raised and rotated, the mirror 17 is exposed forward on the front part of the upper circumferential surface 2b of the lower case 2 and serves its purpose. Therefore, the mirror 17 is located in the lower case 2.
Although it is integrated into the mirror 17 so that it is not lost, it can effectively prevent the mirror 17 from being scratched or fogged when not in use, and the mirror 17 is exposed at a position where it can be easily seen when in use. But it's extremely easy to use.

In particular, since the mirror 17 is located at the front surface directly below the upper case 1 during use, even when one hand is gripping both the upper case 1 and the lower case 2, the mirror 17 cannot be moved to the lower case. Unlike the configuration in which the mirror 17 is positioned near the lower end of the mirror 17, the lower end of the lower case 2 is grasped with the ring finger and little finger, and the thumb, index finger, and middle finger are supported by the upper case 1 in an open state. The mirror 17 becomes even easier to see as if it were in the palm of your hand.
It is difficult for the fingertips to touch the surface, which is advantageous in preventing fogging.
