Description

[Detailed description of the invention] Technical field This invention relates to a safety razor.

BACKGROUND OF THE INVENTION Conventionally, there have been safety razors in which a shaving blade is sandwiched between a plastic blade holder and a top plate, and these are further clamped and fixed at the tip of a holder. In addition, there is a two-blade safety razor in which one razor blade is sandwiched between a blade holder and a spacer, and these are clamped and fixed at the tip of a holder.

However, with a safety razor of this kind of structure, it is difficult to assemble the razor blade, spacer, and top plate one by one to the blade holder (
The assembly work was extremely troublesome.

Purpose This invention was made to solve the above-mentioned problems, and its purpose is to provide a safety razor that can reduce the number of parts to be assembled and simplify the assembly work. .

EXAMPLE Hereinafter, an example of a safety razor embodying the present invention will be described with reference to the drawings.

In FIG. 1, 1 is a plastic blade holder,
Fitting recesses 2 are provided on both left and right sides of the upper surface as shown in Figure 4.
is recessed, and a pair of left and right through-holes 3 are transparently provided inside thereof, as shown in FIG. A top plate member 4 is connected to the rear side of the blade holder 1 via a pair of left and right first connecting parts 5, and is integrally formed with the blade holder 1. A caulking pin 6a is formed at a position corresponding to the mating recess 2, and a supporting pin 6b having a long diameter the same as the inner diameter of the circumferential hole 3 is formed at a position corresponding to the through-hole 3. In this embodiment, the support pin 6b is slightly longer than the caulking pin 6a. As shown in FIG. 2, the first connecting portion 5 is formed to be bendable and thin.

Reference numeral 7 denotes a spacer member connected to both left and right end portions of the top plate member 4 via second connecting portions 8, and is integrally molded with the blade holder 1 and the top plate member 4. 4
Through holes 9 are transparently provided at positions corresponding to the caulking pin 6a and the support pin 6b. Like the first connecting part 5, the second connecting part 8 is formed to be bendable and thin.

Next, a method of assembling two razor blades to the safety razor blade holder 1 constructed as described above will be explained.

As shown in FIG. 6, the hole 11a of the upper blade 11 as a shaving blade
the caulking pin 6a and the support pin 6 of the top plate member 4, respectively.
After fitting the above blade 11 onto the top plate member 4, bend the spacer member 5 as shown in FIG. The upper blade 11 is sandwiched between the spacer member 7 and the top plate member 4.

Next, the hole 12a of the lower blade 12 serving as a shaving blade is fitted into the caulking pin 6a and the support pin 6b, and placed on the spacer member 7. Then, in this state, the two caulking bins 6a on the left and right ends are crushed as shown by the 7th N: dotted chain line.
The upper and lower blades 11 and 12 and the spacer member 7 are caulked and fixed to the top plate member 4.

Next, when this top plate member 4 is bent as shown in FIG.
The pair of left and right inner support pins 6b that are not caulked are fitted into the fitting recess 2, and the pair of left and right support pins 6b are fitted into the through hole 3. Therefore, the top plate member 4, the spacer member 7 and the upper and lower double blades 11.12
is assembled to the blade holder 1. From this state, Figures 9 to 1
A clamping portion 13 having a U-shaped cross section at the tip end of the holder 13 shown in FIG.
By sandwiching the top plate member 4 and the blade holder 1 as shown by the two-dot chain line in FIG. 8 at point a, the top plate member 41. Spacer member 7, upper and lower double blades 11.
12 and the blade holder 1 are assembled and fixed to the holder 13, and the work of assembling the two-blade safety razor is completed.

In this way, in this embodiment, the caulking pin 6 is provided on the rear side of the blade holder 1.
Since the top plate member 4 and the spacer member 7 having the support bins 6a and 6b are connected in a bendable manner, the safety razor can be easily assembled by simply bending the spacer member 7 and the top plate member 4. , the assembly work is very easy.

In this embodiment, the support pin 6b was designed to be inserted into the member insertion hole 3 without wobbling, but the support pin 6b was made longer and the head of the support pin 6b was fitted into the blade holder. The support pin 6b may be fixed to the blade holder 1 by protruding from the lower surface of the blade holder 1 and caulking its head.

Next, a second embodiment of the present invention will be described with reference to FIGS. 13 to 19.

In this embodiment, all four caulking pins 6a and support pins 6b, which were protruded from the top plate member 4 in the previous embodiment, are replaced with four caulking pins 21 shown in FIG. A clamping hole 22 penetrating the bottle 21 is provided therethrough.

Then, as shown in FIGS. 17 to 18, the spacer member 7 and the top plate member 4 are bent in the same order as in the above embodiment, and the clinching bottle 21 is fitted into the clinching hole 22 as shown in FIG. 19. When inserted, the top plate member 4, spacer member 7, upper and lower double blades 11.
12 to the blade holder 1 (=I is inserted.Next, the caulking hole 2
By caulking the head of the clinching bottle 21 protruding from the top plate 4, the spacer member 7, and the upper and lower blades 11 and 12 are fixed to the blade holder 1. Then, by inserting and fixing the tip of the holder into the mounting recess 23 for mounting the holder formed on the lower surface of the blade holder 1, the work of mounting the safety razor is completed.

Therefore, in this embodiment, the top plate member 4, the spacer member 7, and the upper and lower blades 11 and 12 are completely fixed to the blade holder 1 with the caulking pin 21, so that the blade holder 1 and the top plate member The present invention can be applied to a safety razor of the type in which the tip of the holder is connected to a blade holder 1, which is different from the holder 13 of the above-described embodiment, which holds the holder.

Next, a third embodiment of the invention will be described.

In this embodiment, the part corresponding to the top plate member 4 provided in the previous embodiment is omitted, and a spacer member 7 is bendably connected to the rear side of the blade holder 1. A caulking pin 25 is provided in a protruding manner at a position corresponding to the through hole 9 of the member 7. Then, as shown in FIGS. 25 and 26, after fitting the lower cutter 12 into the caulking pin 25, the spacer member 7 is bent and its through hole 9 is fitted into the caulking pin 25. Next, after fitting the upper blade 11 into the caulking pin 25, as shown in FIG. 13, the assembly is completed.

Therefore, in this embodiment, since the top plate member 4 is omitted, one bending operation is omitted, which simplifies the assembly operation.

Furthermore, in this embodiment, if the upper blade 11 is not assembled at J5 and the caulking pin 25 is caulked against the spacer member 7, it can be applied as a single-blade safety razor.

Note that the present invention is not limited to the above-mentioned embodiments, but can also be implemented in the following embodiments.

(a) As shown in FIGS. 28 and 29, the top plate member 4 is attached to the right side of the blade holder 1, and the spacer member 7 is attached to the outside of the top plate member 4 via the connecting portions 5.8. The spacer member 7 and then the top plate member 4 are connected so that they can be bent and then the top plate member 4 is bent.

(b) As shown in FIGS. 30 and 31, the top plate member 4 is attached to the right side of the blade holder 1 via the connection part 5, and the spacer member 7 is attached to the left side of the blade holder 1 via the connection part 8. The spacer member 7 and then the top plate member 4 are foldably connected.

Effects As detailed above, this invention reduces the number of parts to be assembled and simplifies the assembly work by bendably connecting the holding member for holding the razor blade to the rear side of the blade holder. It is an excellent product for industrial use as a safety razor.
