Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure of a long razor having a holder substantially along a direction in which a blade edge of the blade extends.

[0002]

2. Description of the Related Art Conventionally, such a long-handled razor is disclosed, for example, in Japanese Utility Model Laid-Open No. 58-68272.
In this long handle razor, a spare blade support is rotatably supported by the head of the holder, and a cartridge spare blade is detachably fitted to a rail of the spare blade support.

[0003] As for the rotation preventing means of the blade support, a pivot rod protruding from the blade support main body is inserted into a pivot hole of the head, and the blade support main body is engaged with a long groove of the head. This engaged state is maintained by the elastic force of the compression coil spring wound around the pivot hole. Then, when the replacement blade support is pulled out against the elastic force of the compression coil spring and the replacement blade support body is pulled out from the long groove, the replacement blade support can be rotated together with the cartridge replacement blade.

With respect to the retaining means for the cartridge replacement blade, a lock portion is formed on the rail of the replacement blade support, and when the rail is fitted into the fitting groove of the cartridge replacement blade, the lock portion engages with this fitting groove. The cartridge replacement blade is stopped so that it does not fall off.

According to this long handle razor, the direction of the edge of the blade body can be changed by rotating the cartridge replacement blade, so that it is easy to use.

[0006]

However, the above-described detent means and detent means have completely different structures.

Therefore, the present invention simplifies the structure of the anti-rotation means and the anti-separation means by combining them and using them together.

[0008]

As shown in the drawings of the embodiments described later, a razor according to the present invention includes a head 2, a blade base 10, and a blade assembly 13 of a holder 1, and a blade is attached to the head 2. The table 10 is rotatably supported. A fitting groove 14 is formed in the blade assembly 13, and the blade base 10 is fitted in the fitting groove 14.

A protrusion 12 is formed on the blade base 10, and a locking portion 15 is formed on the fitting groove 14. And the blade rest 1
0 is fitted into the fitting groove 14, the projection 12 protrudes from the fitting groove 14 and is pressed by the locking portion 15 so that the blade assembly 13 is positioned with respect to the blade base 10. It has become.

A recess 9 is formed in the head 2. The protrusion 12 and the recess 9 are engaged with each other at a plurality of use positions where the blade base 10 is rotated with respect to the head 2, so that the blade base 10 can be positioned with respect to the head 2.

[0011]

The projection 12 of the blade base 10 not only engages with the recess 9 of the head 2 to prevent the rotation of the blade base 10 with respect to the head 2 but also forms a fitting groove for the blade assembly 13. It is pressed by the locking portion 15 of 14 and also prevents the blade assembly 13 from coming off the blade base 10.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a long handle razor according to the present invention will be described below with reference to the drawings. As shown in FIG. 1, the holder 1 includes a head 2 and a grip 3. A flat support surface 6 is formed between the back 4 and the abdomen 5 of the head 2 on both sides of the head 2. A stopper projection 7 is formed on the distal end surface of the head 2, and a stopper groove 8 is formed on the abdomen 5 at the base end of the head 2. A detent recess 9 is formed on each of the support surfaces 6 of the head 2 on the distal end side and the proximal end side, respectively.

A pair of blade bases 10 are provided on the support surface 6 of the head 2.
The two blade bases 10 are connected to each other by a connecting portion 10a to form a U-shape, and the distal ends 10b of the both blade bases 10 are separated from each other.
The head 2 is inserted between the two blade bases 10 so that the head 2
The two supporting surfaces 6 face the inner surface of the blade base 10 with a slight gap therebetween, and in this state, the spindle 1 is attached to the both blade base 10 and the head 2.
1 is inserted. Therefore, the double blade rest 10 is
1 can be rotated along both support surfaces 6 of the head 2. Inside the both blade bases 10, detent protrusions 12 are formed to protrude on the distal end side and the proximal end side, respectively. The support shaft 11 is provided between the both detent concave portions 9 and the both detent convex portions 12.
The distance between the support shaft 11 and the double-stop non-rotation recess 9 or the double-stop non-rotation protrusion 12 is equal to each other.

As shown in FIGS. 3 and 4, the blade assembly 13
Is a conventional T-shaped razor replacement blade cartridge,
The blade edge 13a is exposed on the front side. As shown in FIGS. 1 and 2, a fitting groove 14 is provided on the back side of the blade attachment body 13 so as to extend along the direction in which the blade edge 13 a extends. The fitting groove 14 is opened between both edges along the extending direction of the cutting edge 13a, and a plurality of sets of locking portions 15 are protrudingly provided on both edges thereof. When one of the blade bases 10 is fitted into the fitting groove 14 of the blade assembling body 13 from the tip 10b of the blade base 10, as shown in FIG.
Project from between the two locking portions 15 of the fitting groove 14, and
It is pressed by the locking portions 15. Therefore, the blade assembly 13 does not fall off the blade base 10.

When the blade base 10 is rotated in the direction indicated by the arrow A in FIG. 1, the connecting portion 10a between the blade bases 10 is engaged with the stopper groove 8 of the head 2 as shown in FIG. The inner surfaces of the two blade bases 10 overlap with the two support surfaces 6 of the head 2, and the respective detent protrusions 12 of the both blade bases 10 are engaged with the respective detent recesses 9 of the both support surfaces 6. Therefore, the double blade base 10 and the blade assembly 13 are positioned on the head 2.

On the other hand, when the two-blade base 10 is rotated in the direction of arrow B in FIG. 1, the connecting portion 10a between the two-blade bases 10 is locked by the stopper projection 7 of the head 2 as shown in FIG. The inner surface of the double blade base 10 overlaps with the two support surfaces 6 of the head 2, and the respective detent protrusions 12 are engaged with the respective detent recesses 9 in the same manner as described above, so that the double blade base 10 and the blade assembly 13 are formed. It is positioned on the head 2.

In this embodiment, in particular, as shown in FIG. 2B, each detent protrusion 12 of the blade base 10 engages with each detent recess 9 of the head 2 so that the blade base 10 Not only is the rotation stopped, but also each of the rotation preventing protrusions 12 is pressed by both locking portions 15 of the fitting grooves 14 of the blade assembly 13, and the blade assembly 13 comes off from the blade base 10. They have also stopped. Therefore, each of the projections 12 can be used as both a rotation preventing structure and a retaining structure, and these structures are simplified.

The long-handled razor constructed as described above is used, for example, in the state shown in FIG. 3 or FIG. In the above-described embodiment, the case where only one of the two blade bases 10 is fitted to the blade assembly 13 has been described, but the same applies to the case where the blade mounting body 13 is fitted to the other blade base 10. is there. Further, the blade assembly 13 may be fitted to the double blade base 10.

Further, in the above-described embodiment, the head 2 supports the pair of blade bases 10, but it is also possible to support only one blade base 10.

[0020]

According to the present invention, a razor in which the blade assembly 13 is rotatable with respect to the head 2 of the holder 1 together with the blade base 10 in order to make it easier to use. Structure and blade assembly 13 for blade base 10
Part of the stopping means with the retaining structure
, The structure can be simplified.
