The count value is increased to provide a means for the user to easily determine the blade replacement time.
[Selected Drawing] FIG.

Description

The present invention relates to a so-called blade replacement type shaving device that holds a replacement blade in a T-shape on one end side of a rod.

The blade replacement type shaver has been improved into a shaver that is comfortable and comfortable for the user, with improvements such as a simple and reliable replaceable blade replacement method and a complicated structure of the replaceable blade itself. .

The above-mentioned type of shaving device has been provided to users with various improvements such as providing a safe mechanism that does not damage the skin by pursuing sharpness or messy use.
However, the replacement of the blade is left to the user's will, and the user can also replace it after a certain period of time, or use it to determine the replacement time from its sharpness. The blade was being replaced. As a result, regardless of the performance of the shaving device, a situation such as a light injury due to a sharpened blade and a situation where the shaving act itself was abandoned due to lack of spare blade replacement.

Means to solve the problem

The present invention is provided with a counter (counter) in the shaving machine body so that the user can easily and surely notify the blade replacement time with respect to the above-mentioned problems. The count value is increased to provide a means for the user to easily determine the blade replacement time.

Effect of device

The timing for changing the blade of a shaving device is considered to vary greatly depending on the quality of the user's shaving, the location where the shaving device is stored, and the shaving finish preference.
The present invention provides a means for the user to judge the replacement time by counting the individual differences in the replacement time, thereby making it possible to provide further convenience and comfort of the sharply improved shaver.

Since the present invention can be implemented without applying any complicated mechanism to the basic function of an existing so-called replaceable blade type shaver, it can be provided at a low cost and will be described based on the following examples.

FIG. 1 shows a T-shaped shaving device having a structure for holding a replacement blade on one end side of a conventional rod-shaped handle and a structure for attaching and detaching, and is composed of a shaft 1 and a replacement blade 2.
In this conventional shaving device, it is clear that the information that the user can know when the user replaces the blade can only have subjective information such as the comfort and dirt actually used.

FIG. 2 shows a T-shaped shaving device having a structure for holding a replacement blade on one end side of a conventional rod-shaped handle and a structure for attaching and detaching, and a counting portion of the present invention added thereto. It comprises a shaft 1, a replaceable blade 2 and a counting portion 3.

FIG. 3 is an enlarged view of the counting portion, and is composed of a groove 4 formed along the axis, a scale indicating portion 5 sliding along the groove 4 formed along the axis, and a scale 6 engraved on the shaft. Is done.
Here, the scale indicating portion 5 is made of a flexible material so that the user can easily slide the scale indicating portion 5 in the groove 4 and stably stop the support portion at the position of the scale as shown in the figure. .
FIG. 4 shows a cross section of FIG. 3, which is composed of a groove 4 formed along the axis, a scale indicating portion 5 that slides along the axis 4 and a scale 6 engraved on the axis. It shows that.

Here, the counting part of the present invention is that the user advances this scale when the user starts shaving with the shaving device of the present invention or when the shaving is finished, and the shaving device itself counts the number of shavings. Remember. When the user starts or ends the shaving, the user can easily confirm the number of times that the shaving device is performed by looking at the counting portion of the shaving device of the present invention. As described above, by using the shaving device of the present invention, the user himself / herself is freed from managing the number of times of shaving with the shaving device.

FIG. 5 shows another embodiment in which the counting portion has a clock-like scale, and is composed of the shaft 1, the replaceable blade 2, and the counting portion 3 as in the above-described embodiment.

FIG. 6 is an enlarged view of the counting portion 3 of FIG. 5, and the scale indicator portion 7 is attached so as not to be removed from the circular hole 8 of the shaving device body and to rotate. The scale is moved clockwise to memorize the number of times when the user starts shaving or when shaving is finished.

FIGS. 7A and 7B show an embodiment in which a counting device and a replaceable blade attaching / detaching mechanism are interlocked.
The main part is composed of a replaceable blade 2, a scale indicating portion 5, an attaching / detaching rod 10, a replaceable blade fixing portion right 11 that rotates at a fulcrum 14, a replaceable blade fixing portion left 12, and a coil spring 13.
Normally, as shown in FIG. 7 (a), the scale indicator 5 does not push the detachable rod 10 and acts in the direction in which the coil spring 13 extends so that the replaceable blade 2 has the replaceable blade fixing portion right 11 and the replaceable blade fixing portion. 12 is fixed to the main body 1 while being restrained from the left and right.
In other words, if the number of shaves by the user of the shaver is not completed, the scale indicator does not push the detachable rod, so that the replaceable blade 2 remains fixed to the main body.

FIG. 7B shows the time when counting has been completed and the final scale has been reached.
The scale indicator 5 pushes the detachable rod 10 downward, the detachable rod 10 pushes one end of the replacement blade fixing portion right 11 and the replacement blade fixing portion left 12, and the other end of the replacement blade fixing portion right 11 is It rotates counterclockwise around the fulcrum 14 and moves so as to remove the spare blade 2.
Similarly, the other end of the replacement blade fixing part left 12 rotates clockwise around the fulcrum 14 and moves so as to remove the replacement blade 2, and the replacement blade 2 is detached from the main body 1.

The present invention provides a shaving device that is highly convenient at low cost by adding a counting portion with a simple mechanism to the replaceable blade type shaving device.
