Description

[Detailed description of the invention] This invention connects a pair of main body handles to which a cartridge equipped with a shaving blade is attached so that they can be opened and closed so that they can be in a closed state or an open state.
The present invention relates to a cartridge-type razor in which the cartridge and the main body handle are provided with engagement means that allow the cartridge to be detachably attached to the main body handle and to be changed back and forth.

Conventionally, this type of razor blade is described in Japanese Utility Model Application No. 57-47549. In this razor blade, as shown in FIG. 10, a guide 17 is provided on one side of the cartridge 11 so that the skin can be supported between it and the top 13a of the cartridge 11 when shaving. However, if the guide 17 is provided here, when the cartridge 11 is separated from the main body handle 1 for cleaning, the vicinity of the cutting edge of the shaving blade 14 is blocked by the guide 17, making it difficult to remove beard dregs. .

The purpose of the present invention is to prevent the guide from blocking the vicinity of the cutting edge of the razor blade when cleaning the cartridge by providing the guide protruding from the rear side of both body handles which are on the outside when both body handles are closed. To provide a cartridge type razor which can prevent and easily remove beard dregs.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. The pair of main body handles 1 and 2 are in a mutually closed state as shown in FIG. 3 and in a mutually open state as shown in FIG. They are connected so as to be openable and closable via a connecting member 3 so as to be able to be opened and closed. This main body handle 1, 2
When they are closed to each other as shown in Fig. 3, magnets 4 and 5 are placed on their opposing front sides as shown in Fig. 5.
is attached, and its suction force causes the main body handles 1 and 2 to
It is designed to hold the parts in close contact with each other. On the opposing front sides of both main body handles 1 and 2, there is a fifth
As shown in the figure, an engaging protrusion 6 and three stages of engaging recesses 7 are formed, and when the engaging protrusion 6 is engaged with the middle engaging recess 7 as shown in FIG. The parts 1 and 2 are held in close contact with each other so that a shaving blade 14 (to be described later) accurately faces each other without shifting in the vertical direction. Also, as shown in FIG. 8, the engagement protrusion 6 is inserted into the upper engagement recess 7
When engaged, the other main body handle 2 is held in close contact with the one main body handle 1 with the other main body handle 2 being shifted upwardly.
On the other hand, although not shown, if the engaging protrusion 6 is engaged with the lower engaging recess 7, the lower main body handle 2 is held in close contact with one main body handle 1 while being shifted to the other. . These conditions are also displayed by the indicator 8 provided on the left or right side of the main body handles 1, 2.

Hook-shaped support pieces 9 and 10 are protruded from the four corners of the tips of the main body handles 1 and 2, facing each other, and their tips are curved so that the opposing inner surfaces are provided with hook-shaped support pieces 9 and 10 as shown in FIG. Locking convex surfaces 9a and 10a are formed. Cartridge 1 attached to main body handle parts 1 and 2
Reference numerals 1 and 12 denote a head 13 equipped with a shaving blade 14 covered with a comb-like guard 15, as shown in FIG.
and a support leg 16 formed in a wedge shape, and locking concave surfaces 16a are formed on both side surfaces of the support leg 16, as shown in FIG. and,
The support legs 16 of the cartridges 11 and 12 are inserted between the support pieces 9 and 10, and the locking concave surface 1 of the support legs 16 is
6a and the locking convex surfaces 9a, 10a of the support pieces 9, 10 are fitted, the cartridges 11, 12 are moved to the seventh position.
The shaving blade 14 is attached to the main body handles 1 and 2 with the shaving blade 14 facing diagonally upward as shown in the figure, or with the shaving blade 14 facing diagonally downward as shown in FIG.
Moreover, if the cartridges 11, 12 are pulled out against the elasticity of the support pieces 9, 10, the locking convex surfaces 9a, 1
0a and the locking concave surface 16a are disengaged, and the cartridges 11, 12 can be easily removed from the main body handles 1, 2. That is, cartridge 1
1 and 12 can be freely attached and detached from the main body handle parts 1 and 2 and can be changed back and forth. Note that the support pieces 9 and 10 and the support legs 16 support the cartridge 1.
1 and 12 constitute means for engaging the main body handle portions 1 and 2.

As shown in FIG. 3, a guide 17 is provided protruding from the rear side surfaces of both the main body handles 1 and 2, which are the outer sides when the two main body handles 1 and 2 are closed. As shown in FIG.
The guide plate part 19 is constructed between the support parts 18 along the cutting edge of the guide plate part 19, and as shown in FIG. A stepped portion 18a is formed. For example, when the cartridge 11 is attached to the main body handle 1 with the razor blade 14 facing diagonally downward, as shown in FIG.
The tip of one head 13 rests on the stepped portion 18a of the support portion 18.

Next, the operation of the razor thus constructed will be explained.

Now, attach the cartridges 11 and 12 to both main body handles 1 and 2 with the shaving blades 14 facing diagonally upward, and
When both main body handles 1 and 2 are closely held by magnets 4 and 5 while being engaged with the middle engaging recess 7 of both main body handles 1 and 2, the razor blade 14 is held tightly as shown in FIG.
is held in an eight-shape shape at the tips of both main body handles 1 and 2. If the razor blades 14 of the cartridges 11 and 12 are used alternately in this state, shaving can be performed in the reciprocating direction by simply slightly tilting the razor without changing hands.

On the other hand, the engagement protrusion 6 is inserted into the upper or lower engagement recess 7.
Both main body handles 1 and 2 are held together by magnets 4 and 5 while engaged with the magnets 4 and 5.
When the body is held in close contact with the
Alternatively, it is also possible to shave only in one direction using only 2.

Furthermore, the main body handles 1 and 2 can be used as individual razors by releasing the magnets 4 and 5 from their close contact. That is, as shown in FIG. 6, the close contact between the magnets 4 and 5 is released, and both the main body handles 1 and 2 are placed in a 180 degree open state, and the razor blade 14 is held diagonally relative to the main body handle 1 or 2. If the cartridge 11 or 12 is attached with it facing upward, it is convenient for shaving armpit hair, etc. And cartridge 1
It is convenient for normal shaving, etc. by changing the cartridge 1 or 12 back and forth and attaching the cartridge 11 or 12 with the razor blade 14 facing diagonally downward relative to the body handles 1 and 2 (see Figure 9). It is. When shaving in this state, head 1 of cartridges 11 and 12
The skin surface is supported between the top 13a of the guide plate 19 of the guide 17 and the top 19a of the guide plate 19 of the guide 17. In particular, since the guide 17 protrudes from the main body handles 1 and 2, when the cartridges 11 and 12 are removed from the main body handles 1 and 2 for cleaning, the vicinity of the cutting edge of the shaving blade 14 of the head 13 is left open. Makes it easier to remove beard dregs.

As described in detail above, the present invention is such that the pair of main body handles 1 and 2 to which the cartridges 11 and 12 equipped with the shaving blades 14 are attached can be opened and closed so that they can be in a closed state or an open state. Engagement means 9 are connected to the cartridges 11, 12 and the main body handles 1, 2 and allow the cartridges 11, 12 to be detachably attached to the main body handles 1, 2 and to be changed back and forth.
10, 16 are provided on the rear surfaces of both main body handles 1, 2 which are the outer sides when both main body handles 1, 2 are closed. Since the guide 17 that supports the surface is provided protrudingly, as mentioned above, the cartridge 11,
This has the effect of making it much easier to remove beard dregs during washing in Step 12.
