Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a razor in which a handle and a razor head attached thereto face in the same direction and have a guard member at the tip of the blade edge, This invention relates to a razor that can change the working direction of the razor blade by 180 degrees.

BACKGROUND OF THE INVENTION Conventional razors in which the handle and the razor head attached to it face the same direction do not have a guard at the tip of the blade edge. This could cause skin damage when used by unskilled people.

A guard was installed to solve this problem, but the direction of the razor blade remained fixed and could not be changed.

Problems that the invention aims to solve: If the razor head is fixed to the handle and the direction of the razor blade cannot be changed, it is fine when holding the handle with the right hand when shaving the cheeks etc., but when shaving the hairline etc. I had to switch to my left hand. This is because if you turn the razor upside down while holding it in your right hand, the guard will get in the way and you won't be able to shave. There was a need for a razor that could be held in the right hand, as right-handed people could not shave well even if they held it in their left hand.

The present invention aims to eliminate the drawbacks of conventional razors and to provide a razor that can be used by right-handed people with the right hand by making the razor head reversible 180 degrees. Of course, it goes without saying that left-handed people can also use it.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a razor head which is pivotally attached to the tip of the handle so as to be rotatable around its center, and which has a structure in which the handle and the razor head are connected to each other. A locking means is interposed between the two to connect the two, and the razor head and handle can be held together even when the razor head is turned around the pivot shaft so that the front and rear ends of the razor head are reversed. A structure is adopted in which a locking means for coupling is interposed between the two.

Embodiments The following description will be given based on embodiments shown in the drawings. In the drawings, FIG. 1 shows the first embodiment, and FIGS. 2 and 3 show the second embodiment.

The razor consists of a handle 1 and a razor head 2, and the razor head 2 is attached to the tip 3 of the handle 1 and to one side of the handle 1 so as to be in the same direction as the handle 1. The handle 1 is made of plastic and has a flat and elongated shape.

The tip 3 of the handle 1 is divided into two by providing a cut from the tip of the handle 1 toward the center, and two elongated flexible support liquids 4 for supporting the razor head 2 are formed. There is. Opposing protruding shafts 5 are provided to protrude from the inside of the tip of each support liquid 4 at a constant distance.

The two protruding shafts 5 have the same center. Opposing plate portions 6 protrude from the inside of each support liquid 4 at a constant distance. The distance between the two plate parts 6 may be parallel, or may be slightly narrower toward the back.

The razor head 2 is constructed by sandwiching a stainless steel blade body 9 between a head body 7 made of plastic and a blade holding plate 8.

Four protrusions 10 are provided on the back surface of the blade holding plate 8.
On the other hand, the blade body 9 and head body 7 are each provided with four holes 11 and 12 corresponding to these protrusions 10. The blade body 9 is clamped and fixed between the head body 7 and the blade holding plate 8 by passing the protrusion 10 through the holes 11 and 12 of the blade body 9 and the head body 7, and melting and crushing the head of the protrusion 10. be done. A bearing portion 13 is protruded from the center of the back surface of the head body 7 (the side not in contact with the blade body 9), and this bearing portion 1
a long hole 14 for receiving the protruding shaft 5 of the handle 1 in the lateral direction of the handle 1;
is installed through it. Since the support liquid 4 of the handle 1 has flexibility, the support liquid 4 is spread until the protruding shaft 5 is expanded to be wider than the width of the small Ill receiving part 13, and the protruding shaft 5 is inserted into the elongated hole 14. The protrusion 1Ftl15 moves back and forth in the longitudinal direction of the head body 7 within the elongated hole 14.

Projections 15 for locking the razor head 2 to the tip 3 of the handle 1 are provided on both longitudinal sides of the bearings 13 on the back surfaces of the spatula 1 to the main body 7. The thickness of this protrusion 15 is approximately the same as the width between the plate parts 6 of the handle 1. A disk 16 is integrally formed on the upper part of this protrusion 15, and the diameter of the disk 16 is slightly shorter than the distance between the support liquid 4 of the handle 1, and the surface of the head body 7S and the lower surface of the disk 16 are The distance therebetween is approximately the same as the thickness of the plate portion 6 of the handle 1.

A guard portion 18 is formed integrally with the head body 7 so as to extend in the longitudinal direction beyond the blade edge 17 when the blade body 9 is attached to the head body 7.

After the razor head 2 is pivoted to the tip 3 of the handle 1, the razor head 2 is pulled forward and the disk 16 of the locking protrusion 15 is brought into contact with the front end of the plate part 6, and then the razor head 2 is moved parallel to the handle 1. When the razor is moved rearward, the locking protrusion 15 enters between the plate portions 6, and the razor head 2 is locked to the tip 3 of the handle 1. To change the direction of the blade edge 17, pull the razor head 2 forward, turn the razor head 2 around the protrusion 5, and push the locking protrusion 15 on the opposite side between the plate parts 6.

In the first embodiment, the razor head 2 is inverted in front of the handle 1 about the longitudinal axis of the handle 1. Next, a second embodiment will be described in which the razor head 21 is inverted around the horizontal axis of the handle 22 at the side surface of the tip 23 of the handle 22.

The razor consists of a handle 22 and a razor head 21, and a shaft hole 24 is bored in the tip 23 of the handle 22 in the lateral direction. The razor head 21 includes a head body 25 and a blade holding plate 26.
The blade body is clamped and fixed between the two. A cylindrical bearing portion 27 is protruded from the center of the back surface of the head body 25, and a bearing hole 28 is bored in the bearing portion 27. The razor head 21 is reversibly fixed to the handle 22 by passing the bearing portion 27 through the shaft hole 24 of the handle 22 and inserting the shaft pin 29 into the bearing hole 28 from the opposite side.

Two flexible locking pieces 30 are provided on both sides of the bearing portion 27 on the back surface of the head body 25 and project from opposite sides of the blade edge. The cross sections of these locking pieces 30 are L-shaped, and locking protrusions 31 extend inside the tips thereof.

On the other hand, a portion 32 of the tip 23 of the handle 22 that is located inside the shaft hole 24 and corresponds to the locking piece 3o has a width and length that can fit into the locking piece 3o.

DETAILED DESCRIPTION OF THE INVENTION As described above, the present invention allows the razor head to be pivoted at the tip of the handle, and the razor head is coupled to the handle when the blade edge is facing upward or downward, so that it can be used with one dominant hand. You can do both shaving and shaving while holding the razor. In other words, when shaving, use the blade with the edge facing down, and then flip the razor head while holding it with your dominant hand to get a closer shave.

Furthermore, the front half of the razor's blade edge is actually used, while the rear half is not easy to use and is often not used. Therefore, by making the razor head reversible, if the front half of the blade edge is used and the razor head is reversed, the unused rear half will come to the front. By arranging both halves in this manner, one blade can be used for a longer period of time than before.
