Abstract

PROBLEM TO BE SOLVED: A conventional safety razor is mainly a T-shaped safety razor, and it is standardized in shape and structure, such as consideration for individuality such as right-handed and left-handedness of the user and movement to shave at right angles to the beard. Yes, and limited in operability.
The means for solving the problems of the present invention is to connect the shaver (shaving blade) and the handle (grip handle) by moving (sliding) the center crossing shaft connecting portion to the right or left, and further connecting the shaver and the handle. An L-shaped shape and structure in which the shaver is front-facing at the cross axis and the mounting angle with respect to the handle is an obtuse angle, and further, the shaver and handle cross-axis connecting portion is curved toward the center of the handle. Shaving the elbow with a hand that is different to the shaver movement, shaving and paying shaving, complex facial irregularities, and smooth shaving and shaving of shavers for both light and dark beards Allows for easy movement and control.

Description

  The present invention relates to an improvement of a safety razor in which a shaver (shaving blade) and a handle (grip handle) are formed in a T shape.

  Conventional razor safety razors include T-shaped safety razors and linear razors. Among them, the T-shaped safety razor is the mainstream, is standardized in shape and structure, is uniform, and is limited in operability.

  In addition, because it is intended for an unspecified number of users in production, it is made with standard specifications, so it uses facial irregularities, skin hardness, beard softness, right-handed left-handed characteristics, etc. There were problems such as consideration for the individuality of the person and the burden on the elbow and wrist.

  Next, the T-shaped safety razor has a shape and structure (shaving by moving the fulcrum) to shave at right angles to the beard, and a shape and structure for shaving from the side and oblique to the beard (shaving with the fulcrum fixed) There is no one with. The only straight razor that has the shape and structure to shave as sharp as it is is sharp, but there are problems in usability and safety, and it is not used for daily shaving.

  Efficient transmission of force from the handle to the shaver ensures a complex face asperity, different skin qualities, and a shape and structure that ensures easy operation such as smooth movement and control of the shaver for any whisker Propose.

  In addition, we propose a shape and structure that takes into account the characteristics of the right-handed and left-handed, especially the individuality of the user.

  Next, as a shaving method, we propose a structure consisting of a shaver and a handle, in which a shaving method of pulling and shaving is used together with a shaving method of pulling and shaving.

  As a means for solving the problems of the present invention, the first aspect of the present invention is to slide (move) a central cross axis connecting portion of a shaver (shaving blade) and a handle (grip handle) to the right or left. It is an L-shaped safety razor characterized by having a connecting structure. It adapts and specializes in the characteristics of right-handed and left-handed people in the individuality of the person who uses it. In addition, it is possible to transmit delicate power to the tip, center, and rear of the shaver, allowing partial use of the shaver, for complex facial irregularities, and for both dark and light beards Even effective shaving and smooth movement, control and so on.

  The invention according to claim 2 is an L-shaped safety razor characterized by having a structure in which the shaver is in front and the mounting angle with respect to the handle is an obtuse angle at the axis of intersection of the shaver and the handle. By having an obtuse angle in this way, a structure in which the shaving is performed by pulling at a right angle with respect to the whiskers up to now and moving the shaver to a fulcrum and then shaving by shaving is used together. As a result, while maintaining the L-shape, the safety is maintained as before, the movement of the smooth shaver is maintained, and a sharp cut is ensured in a beard such as a dark beard / rigid beard or a portion that is difficult to warp.

  Further, the invention according to claim 3 is an L-shaped safety razor characterized by having a curved shape from the crossing shaft connecting portion between the shaver and the handle toward the center of the handle. This ensures a favorable angle of the shaver that touches the skin in the operability of the shaver held by the dominant hand, and provides a curve that exhibits a curved shape that is not a straight line that facilitates effective shaving, smooth movement, control, etc. Secure a space that contributes to operability. As a result, the characteristics of the L-shaped safety razor are applied to the right-handed and left-handed, the transmission of power to the shaver is efficient and effective, the burden on the elbow and wrist is reduced, and the sharp cutting method with a structure to shave by paying. It becomes a shape that demonstrates its characteristic function.

  In addition to the T-shaped safety razor and the linear razor that have been mainstream until now, the idea of the L-shaped safety razor having an L-shaped shape and structure has the effect of broadening the choice of users.

  This L-shaped safety razor is specialized for the right-handed and left-handed because of its shape and structure. The L-shaped razor that has a pure angle in the right hand is an L-shaped razor that has a pure angle in the right hand and the left hand. Becomes left-handed only. As a result, it is possible to provide a razor that adapts to the dominant arm of the user from a standardized one and takes into account the individuality of the beard.

  And the structure where the central cross axis connecting part of the shaver (shaving blade) and the handle (grip handle) is slid (moved) to the left or right to make the mounting angle an obtuse angle, and the center of the handle from the cross axis connecting part of the shaver and the handle The shape that curves toward the part transmits the force more efficiently from the grip of the handle by the dominant hand to the tip of the shaver, facilitates smooth movement and control of details, and eases the burden on the elbow and wrist The effect of improving operability.

  (A) is drawing which shows the front of embodiment of the safety razor which concerns on this invention. Here, the shaver is slid (moved) about 5.0 mm to the left or right in the central cross axis connecting part of the shaver (shaving blade) and the handle (grip handle), and the shaver is moved to the front at the intersection angle between the shaver and the handle. An L-shaped safety razor characterized by having an obtuse angle with respect to the handle, approximately 97.5 degrees {desirable range is within 90 degrees + (7.5 degrees ± 2.5 degrees)} It is. (B) shows the side surface of the embodiment of the safety razor according to the present invention, and is a drawing showing a curved shape from the intersection shaft connecting portion of the shaver and the handle toward the center of the handle.   It is drawing of the similar example which shows the shape of the safety razor which concerns on this invention. (A) is the L-shaped safety razor of this invention. (B) is the most commonly used T-shaped razor. (C), (d), and (e) are similar razor shapes having an angle between the shaver and the handle, but each has an angle of 90 degrees. It has a sharp angle of within. Moreover, (f) is a linear razor which is generally popular.   (A) is a drawing showing how to shave with the elbow of the dominant hand as a fulcrum, which is a feature of the present invention, which is a characteristic of the razor adapted to the dominant hand. (B) and (c) are drawings showing how to shave by pulling at right angles to the beard as seen in existing and similar razors and moving the elbow together with the shaver.
