Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for supporting a razor head on a holder in a T-shaped razor in which a holder and a razor head are separated.

[0002]

2. Description of the Related Art Conventionally, as a T-type razor of this type, for example, there is one shown in Japanese Patent Publication No. 50-28717. In this T-type razor, a pair of support arms are extended at the upper end of the holder, and a pair of support walls formed on the lower surface of the razor head are provided with support holes. A support shaft is engaged in both of these support holes. In addition, a plate spring portion having a doubly supported beam shape is formed between the support arms at the upper end of the holder, and a pressing surface is formed between the support walls on the lower surface of the razor head. The pressed protrusion is engaged with this pressing surface.
When the razor head is applied to the skin during use, a force is applied to the razor head, so that the razor head rotates with respect to the holder about the support holes and the support shaft by a certain range angle. At that time, the pressing surface on the razor head side presses the pressing protrusion on the holder side, and the leaf spring portion bends against its elasticity. When the razor head is removed from the skin when not in use, the force on the razor head is released, and the elastic force of the leaf spring part presses the pressing surface, and the razor head also rotates and returns to its original state. ..

[0003]

In such a holder, in addition to both supporting arms, a leaf spring portion must be formed between them, which has the drawback of complicating the shape of the holder.

Further, since there is some rattling between the support hole on the razor head side and the support shaft on the holder side, in the above-mentioned structure in which only one central portion of the razor head is pressed, the razor is moved relative to the holder. When the head rotates, the movement of the razor head may become unstable.

The present invention simplifies the structure of the holder by effectively utilizing both supporting arms of the holder to press the razor head, and the supporting both arms press two positions of the razor head. The purpose is to stabilize the movement of.

[0006]

As shown in the drawings of the embodiments to be described later, in a T-type razor according to the present invention, a pair of support arms 2 are extended from the upper end of a holder 1 and a razor is also provided. A pair of support walls 6 formed on the lower surface of the head 5.
Support holes 7 are formed in the support holes 7. The support shafts 3 formed in the support holes 2 are engaged in the support holes 7 so that the razor head 5 moves the support shafts 3 and the support holes 7 to the holder 1. It is designed so that it can rotate around a certain range of angles.

The both supporting arms 2 are further provided with a pressing surface 4a.
And a pressing surface 8a is further formed on both support walls 6 of the razor head 5, and the pressing surface 4a is formed.
And the pressing surface 8a are engaged with each other. Then, when the razor head 5 rotates with respect to the holder 1, the pressing surfaces 4a of the supporting arms 2 are pressed by the pressing surfaces 8a of the razor head 5, so that both supporting arms 2 themselves become elastic. There is.

[0008]

When not in use, the razor head 5 is inclined forward with respect to the holder 1 as shown in FIG. When the razor head 5 is applied to the skin during use, as shown in FIG.
Rotates with respect to the holder 1 about both support holes 7 and both support shafts 3 by a certain range angle. At this time, as shown in FIG. 6, both pressing surfaces 8a of the razor head 5 press the pressing surfaces 4a of both supporting arms 2 in the arrow direction, so that both supporting arms 2
It bends in the vertical direction Q against its elasticity. When the razor head 5 is separated from the skin when not in use, the pressing force 4a of the support arms 2 presses both pressing faces 8a of the razor head 5 due to the elastic force of the support arms 2, and the razor head 5 similarly rotates and returns to its original state. Return.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A T-type razor according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a pair of support arms 2 are provided at the upper end of a holder 1 made of plastic, and both support arms 2 are thinner than the base 2a thereof as shown in FIG. Therefore, it can bend in the vertical direction Q and the horizontal direction R orthogonal to the extending direction P. A support shaft 3 is provided at the tip of each of the support arms 2 so as to face each other and project in the left-right direction R.

Particularly, a hemispherical pressing protrusion 4 is formed on both of the support arms 2 so as to face each other in the left-right direction R between the support shaft 3 and the base portion 2a. Razor head 5 as shown in FIG.
The support walls 6 formed on the left and right sides of the lower surface of the
The support hole 7 is provided as shown in FIG. A pressing recess 8 is further formed on both of the support walls 6. Figures 3 and 4
As shown in FIG. 2, slanted pressing surfaces 8a are formed in the pressing recesses 8 on both sides of a direction S orthogonal to the center of rotation connecting the support holes 7.

Both support arms 2 of the holder 1 have a razor head 5
The support shafts 3 of the two support arms 2 are engaged in the support holes 7 of the razor head 5, so that the razor head 5 is attached to the holder 1 by the support holes 7 and the support shafts 3 thereof. It is possible to rotate about a certain range angle around.

In particular, the pressing projections 4 of both support arms 2 are engaged with the pressing recesses 8 of the razor head 5, and the pressing surfaces 4a on the outer periphery of the pressing projections 4 contact the pressing surfaces 8a of the pressing recesses 8. Has been done.

When not in use, the razor head 5 is inclined forward with respect to the holder 1 as shown in FIG. When the razor head 5 is applied to the skin at the time of use, the razor head 5 is held by the razor head 5 with respect to the holder 1 as shown in FIG.
Rotate about a certain range angle. At this time, as shown in FIG.
Since the pressing surface 4a is pressed in the direction of the arrow, both supporting arms 2 themselves bend in the vertical direction Q against the elasticity thereof. When the razor head 5 is separated from the skin when not in use, the pressing surfaces 4a of the support arms 2 are forced to move by the elastic force of the support arms 2.
Then, the razor head 5 is similarly rotated to return to the original state.

In the holder 1 according to the present embodiment, not only the support shaft 3 but also the pressing projection 4 are provided on both support arms 2, so that the original function of rotatably supporting the razor head 5 is obtained. In addition, both supporting arms 2 can also be provided with a function of urging the razor head 5 in the rotation direction thereof.
Unlike the prior art, it is not necessary to form a leaf spring portion between both support arms 2 and the structure is very simple.

Further, since the pressing protrusions 4 of both supporting arms 2 can press the lower surface of the razor head 5 on both left and right sides, respectively, between the supporting holes 7 of the razor head 5 and the support shaft 3 of both supporting arms 2. Even if there is rattling, the support shaft 3 is pressed against the support hole 7 by the elastic force of both support arms 2,
Not only the rattling can be absorbed, but also the movement of the razor head 5 is very stable because it is pressed by two places.
