[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved razor head guard in a T-type razor in which a razor head is provided at the upper end of a holder.

[0002]

2. Description of the Related Art Conventionally, in a T-type razor of this type, it is possible to change the angle of inclination of a shaving surface connecting a guard provided to the blade edge of the blade body and the blade edge of the blade body with respect to the blade body. Various things have been devised. For example, as a type in which the guard moves with respect to the blade base or the blade body, the actual opening 55-
There are those disclosed in Japanese Patent No. 136453 and Japanese Utility Model Laid-Open No. 55-143175. In this T-type razor, since the guard, the guard movement guide portion, and the movement operation portion are provided separately from the blade stand, there is a problem that the number of parts increases and the assembling work becomes troublesome.

[0003]

As described above, the conventional problem is that since the guard moving means is separated from the blade base, the number of parts is increased. In the present invention, the guard moving means is separated from the blade base. The purpose is to reduce the number of parts by providing them integrally.

[0004]

In view of this object, in the T-type razor according to the present invention, as shown in the drawings of each embodiment described later, a blade body 15 is provided between a blade base 8 and a top plate 5. A razor head 16 is attached to the upper end of the grip portion 2 in a T shape and extends to both sides of the grip portion 2. The blade body 15 exposed in a direction orthogonal to the extending direction of the razor head 16.
The guard 12 is integrally provided on the blade mounting plate 9 of the blade base 8 via the support arm 10 so as to correspond to the blade edge 15a of the.
When the guard 12 is moved with respect to the blade mounting plate 9 of the blade base 8 by the deformation of the support arm 10, the inclination angle θ formed by the shaving surface P connecting the guard 12 and the blade tip 15a with respect to the blade body 15 is 2 or more. Can be changed to the state of. The position of each guard 12 can be held by locking means 7, 14, 19, 20.

[0005]

When the guard 12 is moved by the deformation of the support arm 10, the tilt angle θ becomes large at the position of the guard 12 shown in FIGS. At the 12th position, the inclination angle θ becomes small and the shaving feel becomes soft.

[0006]

[First Embodiment] First, a first embodiment of the present invention will be described with reference to FIGS.
Follow the instructions below. In the holder 1 made of metal,
A mounting base 3 is provided in a T shape with respect to the grip portion 2 at an upper end portion of the grip portion 2 and extends to both left and right sides of the grip portion 2. This mounting base 3 is bent to have a U-shaped cross section, and has a base plate 4 and a top plate 5.
And the fitting space 6 formed between them is open in the forward direction orthogonal to the extending direction of the mounting base 3. A locking groove 7 is provided inside the front edge of the top plate 5 along the extending direction of the mounting base 3.

Blade stand 8 integrally formed of plastic
In, the support arms 10 are provided on both left and right sides. The support arm 10 is composed of a leaf spring portion 11a extending in the left-right direction from a rear edge portion of the blade mounting plate 9 and a side frame portion 11b extending forward from a tip portion of the leaf spring portion 11a. A guard 12 is installed in front of the blade mounting plate 9 between the both side frame portions 11b, and a whiskers exclusion hole 13 is formed along the guard 12 between the guard 12 and the blade mounting plate 9. A locking protrusion 14 is formed on both side frame portions 11b behind the guard 12. A blade 15 is placed and positioned on the blade mounting plate 9. This blade 15
The blade edge 15a is located above the whiskers removal hole 13, and the guard 12 corresponds to the blade edge 15a at the front position of the blade edge 15a. The blade base 8 is inserted into the fitting space 6 of the mounting base 3 so that the blade base 8 cannot be pulled out forward from the mounting base 3. The blade body 15 is sandwiched between the blade base 8 and the top plate 5, and the blade tip 15a of the blade body 15, the whiskers removal hole 13 and the guard 12 are exposed in front of the mounting base 3. A razor head 16 is constituted by the blade base 8, the blade body 15, and the top plate 5 of the mounting base 3.

Now, as shown in FIG. 2 and FIG.
In the state where both the side locking projections 14 are engaged with the locking grooves 7 of the top plate 5, the inclination angle θ formed by the blade body 15 and the shaving surface P connecting the guard 12 and the blade edge 15a becomes large. , The shaving taste becomes hard. As shown in FIGS. 4 and 5, when the guard 12 is pulled forward, the plate spring portions 11a of both supporting arms 10 bend in the blade stand 8 and the locking protrusions 14 of both supporting arms 10 lock the top plate 5. The guard 12 is disengaged from the groove 7 to the front and is locked by the top plate 5, and the guard 12 is separated from the front of the cutting edge 15a. Therefore,
The inclination angle θ formed by the shaving surface P with respect to the blade body 15 becomes small, and the shaving taste becomes soft.

When the locking projections 14 are pushed into the locking groove 7 by pushing the guard 12, the original state is restored. As described above, in this embodiment, since the deformable support arm 10 is integrally molded between the guard 12 and the blade mounting plate 9 as the moving means of the guard 12, the guard 12 and the support arm 10 are formed.
It is possible to form the blade stand 8 having a single component, the number of components is reduced as compared with the case of the prior art, and the work of assembling the moving means of the guard 12 is simplified.

[0010]

[Second Embodiment] A second embodiment of the present invention will now be described with reference to FIGS. 6 to 10, focusing on the differences from the first embodiment. In the blade stand 8, the blade mounting plate 9 is divided into left and right parts, and a support arm 10 is integrally formed from each blade mounting plate 9. A whiskers exclusion hole 13 is formed between the guard 12 integrally formed between the support arms 10 and the front edge portions of the left and right mounting plates 9. The locking arm 17 which is integrally projected from the central portion of the guard 12 is extended between the left and right mounting plates 9,
The plate spring portions 18 formed on both the left and right sides of the locking arm 17 are formed with locking projections 19, and the left and right mounting plates 9 are opposed to the locking projections 19 and are locking projections. 20 are formed. In a state where the blade base 8 is inserted into the fitting space 6 of the mounting base 3, part of the locking arm 17 is attached to the mounting base 3.
It projects rearward from the rear side.

As shown in FIGS. 7 and 8, in the state where both the locking projections 19 of the locking arm 17 are behind the locking projections 20 of the two mounting plates 9, the inclination angle of the shaving surface P is set. θ becomes large and a hard shaving taste is obtained. As shown in FIGS. 9 and 10, when the locking arm 17 is pushed forward, the leaf spring portions 11 a of both arms 10 are bent and both locking projections 19 of the locking arm 17 are bent.
Are positioned in front of the locking projections 20 of the two mounting plates 9 and are locked to each other. Therefore, the inclination angle θ of the shaving surface P
Gets smaller and gains a soft shaving taste.

The guard 12 is pushed to push the locking projections 19 and 20.
When the engagement is released, the original state is restored by the elastic return force of the leaf spring portions 11a of both support arms 10. Also in the second embodiment, the number of parts is reduced and the assembling work is simplified as in the case of the first embodiment. Although the support arms 10 and the guard 12 are integrally formed with the blade mounting plate 9 in the blade base 8 in both of the embodiments, they may be separately formed and integrally attached.

[0013]

[Effect of the Invention] Razor head 1 of T-type razor according to the present invention
According to 6, since the deformable support arm 10 is integrally provided between the guard 12 and the blade mounting plate 9 as the moving means of the guard 12, the number of parts is reduced as compared with the case of the conventional technique. The work of assembling the moving means of the guard 12 is simplified.
