Description

[Detailed description of the invention] The present invention relates to improvements in safety razors.

An object of the present invention is to change the angle between the blade and the handle according to the user's preference. Another purpose is to allow the safety razor to be folded compactly after use. Next, the structure of the present invention will be explained with reference to the drawings showing examples.

The assembled blade body 4 includes two blade bodies 6 between the husband plate 7 and the blade base 8.
6 is clamped and fixed.

Two journal bearings 9 and 10 are bored on each side of the assembled blade body. The holder main body 1 has arms 11, 11 integrally provided at the upper end of the elongated handle 5, and journal shafts 12, 12 extending inward at the upper ends of the arms.
12 stands out. The journal pins 12, 12 are connected to the journal bearings 9, 9 described above. A groove 13 is provided in the longitudinal direction of the handle, and protrusions 14 are provided on both inner sides of this groove.
, 14 are integrally provided. The slider 2 has an iron inserted into the groove 13, and the protrusions 14, 14 are inserted into the grooves 15, 15 provided on both sides of the slider to prevent the slider 2 from coming off from the groove 13. to do. The slider also has an elastic piece 16 extending in its longitudinal direction, and a locking projection 17 integrally projects from the free end of the elastic piece 16 toward the side surface of the handle 5. This locking convex portion 17 changes the position of the slider 1 step by step by locking into a certain locking hole 18 formed in the side surface of the handle. Although the number of locking holes 18 shown in the figure is two, it is also an aspect of the present invention to increase the number to three or more. The auxiliary body 3 has arms 20, 20 protruding from the upper end of the base 19. Inward journal shafts 21, 21 integrally protrude from the upper end of the arm, and are coupled to journal bearings 10, 10 bored in the assembled blade body. The base 19 of the auxiliary body is divided into two parts, and a protruding shaft 22 is integrally provided on each side. This base 1
9 is inserted into a recess 23 provided at the upper end of the slider 2, and the protruding shaft 22 is inserted into two round holes 24 bored on the inner surface of the recess. That is, in the safety razor of this embodiment, the assembled blade body 4, holder body 1, slider 2, and auxiliary body 3 form a four-barreled slider crank chain. Next, the operation of the embodiment will be explained.

As shown in FIG. 1, when the safety razor is not in use, the locking protrusion 17 is locked in the upper locking hole 18.
The angle between the blade 6 and the holder body 1 is 0 degrees,
It can be folded into a compact size. When using the safety razor, when the locking protrusion 17 is locked in the lower locking hole 18 as shown in FIG. 2, the assembled blade body 4 rotates around the longitudinal marking line. Since the blade 6 and the holder main body 1 form an angle, the user can grip the handle 5 and perform the shaving operation. The present invention has the above-described configuration, and by changing the relative positional relationship of the auxiliary body 3 to the holder body 1, the assembly blade can be assembled with the journal joint wire between the holder body 1 and the assembled blade body 4 as the central axis. Since the angle of the holder 4 relative to the holder main body 1 can be changed, a convenient angle can be selected according to the user's preference. In addition, since the connection between the assembled blade body 4 and the holder body 1 and the connection between the assembled blade body 4 and the auxiliary body 3 are both journal connections, the operation of rotating the assembled blade body is smooth, and it can be used for a long time. This has the effect that the joint portion will not be easily damaged even if the

Claims (1)

[Claims] 1. Side surface of assembled blade body 4, holder body 1 and auxiliary body 3
The ends of each arm are connected by journal connection, and the journal connection position between the side surface of the assembled blade body and the holder main body arm, and the journal connection position between the side surface of the assembled blade body and the auxiliary body arm are located at the front and rear sides of the side surface of the assembled blade body. The holder main body and the auxiliary body are separated in the direction, and are connected to each other by almost overlapping each other. By changing the relative positional relationship of the auxiliary body 3 to the holder main body 1, the holder main body 1 and the assembled blade body 4 can be separated. A safety razor characterized in that the angle of the assembled blade body 4 relative to the holder body 1 can be changed with the journal connection axis as the central axis. 2. A patent claim in which the holder main body 1 has an elongated handle 5, a slider 2 is installed in the handle so as to be slidable in the longitudinal direction, and the base of the auxiliary body 3 is pivotably attached to the slider 2. The safety razor described in item 1 of the scope of . 3. The safety razor according to claim 2, wherein the slider 2 is capable of sliding over a necessary distance so that the angle between the blade 6 and the holder 1 can vary from 0 degrees to at least 80 degrees. . 4 The position of the slider 1 when the angle between the blade 6 and the holder body 1 is 0 degrees, the position of the slider 1 when the angle is maximum, and the position of the slider 1 at several slider 1 positions in between. 4. The safety razor according to claim 3, wherein a locking means capable of locking the slider and the holder body is provided between the slider and the holder body.
