Description

[Detailed description of the invention] (Industrial application field) The present invention relates to improvements in safety razors.

(Prior Art) Conventional safety razors, so-called disposable ones, have a blade fixedly connected to the handle at a certain angle, as shown in Figure 5, and are bulky, making them difficult to carry. It was inconvenient.

(Problems to be solved by the invention) The present invention is a disposable safety razor, which
When not in use, the blade portion can be folded to make the entire device thinner, and the purpose is to provide convenient portability.

(Means for Solving the Problems) The configuration of the present invention will be explained with reference to the drawings showing examples.

In this embodiment, the entire safety razor has a thin rectangular shape, and the safety razor is formed into a card shape.

The main body 2 has a thin rectangular shape, and most of it becomes the grip part 1. A pair of arms 7, 7 are provided at the head of the main body with an interval equal to the width of the main body. The arms 7, 7 form a part of the main body 2 and thus form a thin rectangular shape together with the main body 2. A journal bearing 12 is bored in the inner surface of the tip of each arm 7,7. The blade member 3 has a blade 6 sandwiched and fixed between a blade base 4 and a top plate 5, and has the same overall thickness as the main body 2. A guard portion 13 extends at the front edge of the blade rest 4. A journal shaft (not shown) is protruded from both sides of the blade member 3, and a journal shaft (not shown) is provided on both sides of the blade member 3.
2 and 12.

A portion of the head of the main body 2 between the arms 7, 7 is cut out to form a slightly concave arc-shaped slope, and thus the cut portion becomes a space 9. This space 9 is provided so that when the journalled blade member 3 is rotated so that the tip 8 faces toward the top plate 5, the tip 8 can be directed downward. It is something. Further, the main body 2 includes a first engaging means 10 for restricting further rotation of the downwardly facing blade member 3 toward the top plate 5. In this embodiment, the first locking means 10 is an inclined surface forming a concave arc forming the space 9 . Instead of such a slope, the locking means 10 may have a locking protrusion protruding from the lower inner surface of the arms 7, 7, for example.

When the blade member 3 is rotated in the opposite direction, that is, when the tip portion 8 of the blade member is rotated in the direction of the blade base 4,
The main body also has a second locking means 11 to prevent the blade member 3 from further rotating in the direction of the blade base 4 when the blade member 3 forms a predetermined shaving angle with respect to the main body 2. In this embodiment, the second locking means 11 is the upper edge of a slope forming a concave arc forming the space 9, and extends between the arms 7, 7. Instead of the locking means 11, a locking protrusion may be provided on the inner surface of the arms 7, 7, for example.

Note that a means is required to maintain the stable state of the blade member 3 during shaving, and one method is to set the journal connection between the blade member 3 and the arms 7, 7 a little tighter. . Alternatively, the first and second locking means may be snap-type locking means in which a protrusion is inserted into a hole.

(Operations and Effects) The present invention has the above-described configuration, in which the main body 2 is thinly formed into a single plate shape having approximately the same thickness as the blade member 3, and the blade member 3 is disposed within the space 9 of the main body. Because it fits in, it becomes extremely thin when not in use, and can be kept in a pocket, making it convenient to carry. In addition, conventional thin safety razors are complicated to assemble before use, requiring a lot of effort from the user, which offsets the convenience of the thin razor. The present invention provides a thin safety razor that is extremely easy to assemble, since it can be used by simply rotating the blade member 3 with a fingertip, so it can be assembled and used as a safety razor with almost one touch. It has the effect of being able to Furthermore, since the present invention is composed of only one plate-shaped main body 2 of the blade member 3, the structure is extremely simple, and a product that is easy to manufacture and inexpensive can be provided.

In the present invention, the locking means for restricting further rotation of the blade member 3 beyond the use position is the upper edge of the main body extending between the arms 7, 7, and this locking means prevents the blade member 3 from rotating further than the use position. Since it is supported from below, the blade member does not bend during use and can be used in a stable state.

Claims (1)

[Claims] 1. A safety razor consisting of a main body 2 having a grip part 1 and a blade member 3 attached to the main body 2,
The blade member 3 includes a relatively thin blade base 4 and a relatively thin top plate 5.
A blade body 6 is sandwiched between the body 2 and the blade member 3, and the body 2 is thinly formed into a plate shape having approximately the same thickness as the blade member 3, and has a pair of arms 7 at its head. , 7, and a space 9 is provided in the width direction of the rear surface of the main body below the arms 7, 7, and a wall-shaped first locking means 10 is formed in the front of the space 9. Both ends of the blade member 3 are arranged so that when the blade member 3 is in a downward state, the blade member 3 is housed in the space 9 and the top plate 5 is in contact with the wall-shaped first locking means 10. is journalled with the arms 7, 7, and when the blade member 3 rotates more than 270 degrees from this state, a second lock is provided to lock the blade base 4 from below and restrict the rotation of the blade member 3. A safety razor, characterized in that a second locking means 11 is provided, the second locking means being the upper edge of the body extending between the arms 7,7.
