Description

[Detailed description of the invention] In this invention, the assembled blade body and the holder are formed separately, and the assembled blade body can be attached to and removed from the holder as needed, and the assembled blade body that has become dull can be replaced with a new one. It concerns the improvement of safety razors that can be used to improve safety razors.

The purpose of the present invention is to provide a new structure for attaching the assembled blade to the holder, and to facilitate the attachment and detachment of the assembled blade.

Next, the configuration of the present invention will be explained with reference to drawings showing an actual case.

The assembled blade body 3 has a blade sandwiched and fixed between a plastic top plate and a blade holder, and protrusions I having a cross-sectional shape of a letter L are integrated with the blade holder at the four corners of the back of the blade holder. It is installed protrudingly.

A pair of opposing protrusions 7, 7 form a fitting portion 2 for coupling with the holder 1.

The holder 1 is an integrally molded plastic product, and the handle 4
Arms 5, 5 protrude from the top in two directions.

At the end of each arm 5, 5 is a plate-shaped head 6, 6.
are integrally formed, and protrusions 8 are provided on the front and rear edges of the head.
, 8, 8.8 are provided.

The present invention has the above structure, and when attaching the assembled blade to the holder 1, force is applied from the sides of the two arms in the direction of the arrow as shown in FIG. After applying the head to the back surface of the assembled blade body 3, the force is released.

Then, as shown in FIG. 4, the arms 5, 5 will expand to their original state due to their elastic force, at which time each outer end of the head 6.6 will enter into the fitting part 2 and fit therein.

Reference numerals 9, 9 are convex portions that can be moved in the longitudinal direction within a recess 10 provided on the back surface of the assembled blade body.

Convexity ms with respect to the width of the concave portion in the short side direction of the assembled blade body, 9
width is slightly smaller.

Therefore, there is no significant slack between the two.

When trying to attach the assembled blade to the holder, by placing the protrusions 9, 9 in the recess 10, the position for fitting the assembled blade to the head can be determined, so that the installation work can be done quickly. It can be carried out.

Particularly in the case of this embodiment, the protrusions 9, 9 are engaged with both sides 11.11 of the concave part to prevent the arms 5, 5 from spreading too much, and the elasticity of the arms ensures reliable support of the assembled blade body. can.

The present invention has the above-mentioned configuration, and in order to align the positional relationship between the assembled blades when the assembled blades are attached to the holder, the assembled blades are provided with a recessed portion, and the head portion is provided with convex portions 9, 9. The biggest feature is that

As a result, even if the holder is slightly misaligned when the holder is placed on the assembled blade, the two will be aligned the moment they are installed.

The conventional product did not have an excellent deflection prevention means like the present invention, and the user had to worry about the positional relationship and it took time and effort to put it on.The present invention eliminates the troubles of the conventional product. It has excellent effects.

Claims (1)

[Scope of utility model registration request] The safety razor is a combination of a holder 1 and an approximately rectangular parallelepiped assembled blade body 3, and the assembled blade body 3 has a fitting portion 2°2 on the short side of the back side for connecting to the holder 1. The entrances of the sections are each opened toward the other fitting section, and the holder 1 has two elastic arms 5, 5 provided integrally with the top of the handle 4, and provided at each end of the arms. a head 6 including a part for fitting into the fitting parts 2, 2 of the assembled blade body 3;
In a safety razor having a 6° angle, a recess is provided on the back surface of the assembled blade in order to align the positional relationship between the head of the holder and the fitting part of the assembled blade when the assembled blade is attached to the holder. The head is provided with protrusions 9, 9 that are movable within the recess when the assembled blade is attached, and the width of the protrusions 9, 9 is smaller than the width of the recess in the short side direction of the assembled blade. A safety razor characterized by being slightly smaller.
