Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a razor head including a blade support structure and a pair of double row blades permanently secured to the blade support structure, whereby the cutting edges of the blades are blunt. This invention relates to a type of safety razor in which the head of the razor is used as a unit when the situation occurs.

The present invention provides a razor head of this general form which has a particularly simple construction.

In a particular embodiment described in detail below, the support structure is molded of plastic defining a guard portion and a blade platform located behind said guard portion and to which a planar primary blade is secured. A single part, P-shaped, and a secondary blade are formed as part of a metal strip having a shape defining a support leg fixed to the secondary blade, the cap part, and the rear surface of the support structure.

According to a preferred feature of the invention, the support leg is perforated in order to drain away debris passing between the two blades.

Hereinafter, this hot-type miso head υ will be described in detail with reference to the accompanying drawings.

The razor head shown in the accompanying drawings consists of a single piece of plastic molded defining a guard portion 1 and a blade platform 2 having a blade support surface. A planar primary delay 3 is fixed to the blade support surface by a plurality of rivets 4, in this case three, formed integrally with the platform 2. The rivet is initially made from a pipe and is later modified to secure the primary blade in place.

On the rear surface of the platform 2, there is also a secondary blade member T.
t - Similarly integral '1 for fixing in place:.

A rivet 6 is provided.

The secondary blade member 7 (like the primary blade 3) is made of stainless steel and is shaped in cross section to form a secondary blade 8, a one-way cap portion 9 and a lower support leg 11. - by means of the lower support leg 11 A secondary blade member, i.e. a metal strip 7, is fastened to the Delay's A2; Preferably, the rivets 6 of the fins 6 are arranged in the same transverse plane as the rivets 4 for the primary plate 3. Between the rivets 60 and the rivets 6
At a position beyond , the support leg 11 has an elongated large 12
are formed, and the blade platform 2 is formed with cleaning slots 13 aligned with these sizes 12. As can be seen from FIG. 6, which shows half of the primary blade 30, the trailing edge of the primary blade 3 between the protrusions $14 has been removed. A rivet hole 16 is partially formed inside the protrusion 14. Therefore, lli of rivet 4
The part is the only book in the space of the primary plaid 3 and secondary plaid 8, so that the 1rL
Through the space between the blade 3 and the secondary blade 8 a cleaning slot 13 and a hole 12 are reached, which can then be drained outside the rear razor head. The debris falling from the primary blade 3 is discharged through the gap between the guard part 1 and the Zorat indicator 2 in a known manner.

This link can be formed over the entire length of the guard part 1, but is preferably interrupted at regular intervals by narrow webs which serve to reinforce the guard part 1.

At the opposite end of the razor head, the molded razor portion is provided with an integrally formed end wall 15. Due to the end wall portion 15, the whole razor piece is the main gripping portion 1.
It can be conveniently attached to a grill handle equipped with 6 and 1T.

Further, a razor head is fixed in the 1-ri 17.

It will therefore be appreciated that this cooking section is of very simple construction, comprising only three components, and is particularly suitable for draining crumbs. The secondary blade member 8 is provided with increased rigidity by its cross-sectional shape, so that the secondary blade member 8 can be constructed from a relatively thin strip. For example, the secondary plate member 8 may have a thickness of 0.1 cm, while the primary plate member r3 has a thickness of 0.25 cm.

The razor according to the invention) can be attached to the handle to form a fully usable sb removable Kv& or can be used as a replaceable cartridge permanently fixed. It's becoming a trap. In either case, the razor head can be mounted on the handle so that it pivots about an axis parallel to the blade of the blade during use.
