MOUNTING PLATE PROTECTIVE MEMBER FOR DRY SHAVER HEAD Filed July 28, 1958 FIGB FIGJO V INVENTOR PETRUS JOSEPHUS JOHANNES VAES AGENT This invention relates to dry-shavers comprising at least two cutting plates which are surrounded by a common protective member made in one piece.

According to the invention, the protective member extends into the space which exists between the cutting plates.

In known dry-shavers of the kind, to which the invention relates, the protective member does not extend into the space which exists between the cutting plates. Since the properties of the skin very much differ for different persons, grazing of the skin could occur with known dryshavers for persons having a very sensitive skin, since the skin may find itself more or less between the shearing plates and is liable to be pinched between the edges of the plates as a result of the movement of the dryshaver over the skin. According to the invention, it is possible to prevent the skin from being pinched between the shearing plates.

According to another feature of the invention, the ibnterspace is filled up completely by the protective mem- By preference the portion of the protective member which extends into the space between the cutting plates lies at a level lower than that of the outer edge of the protective member.

As a matter of fact, it is possible that for certain persons a protective member which extends between the shearing plates at the same level as the outer edge of the same, results in a less close shave. Now, due to the portion of the protective member which extends between the cutting plates lies at a lower level, an efficacious compromise is obtained between the requirements for satisfactory shaving and non-scraping.

In order that the invention may be more readily carried into effect, several embodiments will now be described more fully, by way of example, with reference to the accompanying drawing.

FIGURE 1 is a plan view of a known double-head shaver in which the cutting plates are jointly surrounded by a protective member made in one piece.

FIGURE 2 is a cross-sectional view of FIGURE 1.

FIGURES 3 and 4 are a plan view of a dry-shaver according to the invention, in which the member extends into the space which exists between the cutting plates without this space being filled up completely.

FIGURES 5 and 6 are cross-sectional views of FIG- URES 3 and 4, respectively, the FIGURES 4 and 6 being modified forms of the basic invention illustrated in FIGS. 3 and 5 respectively.

FIGURES 7 and 8 are a plan view of a dry-shaver in a modified form according to the invention, in which the interspace is filled up completely.

FIGURES 9 and 10 are cross-sectional views of FIG- URES 7 and 8, respectively.

Referring now to FIGURES 1 and 2, shearing plates 1 and 2 are arranged in a plate-like member 3, the outer periphery of which has an elevated rim 4 which surrounds the cutting plates 1 and 2. The rim 4 in this case serves as a protective member and has been made in one piece. The skin can thus penetrate to the space 5 which exists 3,7,884 Patented Jan. 1, 1963 25 between the shearing plates 1 and 2, so that scraping of the skin might occur with persons having a very sensitive skin.

In FIGURES 3 and 5, the outer periphery 6 of a protective member 7 has a shape identical with that of the protective member 4 of FIGURES 1 and 2, but its inner boundary 8 extends into the space which exists between the shearing plates 1 and 2 and comprises a portion 9 which lies at a level lower than that of the remaining part of the protective member 7.

In FIGURES 4 and 6, the inner boundary Ill of a protective member 12 is identical with that of the inner boundary 8 in FIGURE 3. However, its outer boundary 11 has a shape matched to the shape of the inner boundary 10, resulting in a rim of substantially constant width being obtained. As before, the portion 13 is situated at a level lower than that of the remaining part of the ring.

In FIGURES 7, 8, 9 and 10, the space between the shearing plates 1 and 2 is filled up completely by the

protective member

15, 16 respectively. The outer periphery 17 of protective member 15 is identical in shape with the outer periphery 6 of protective member 7 in FIG- URE 3, whilst the outer periphery 18 of protective member 16 has a shape similar to that of the outer periphery 11 in FIGURE 4. In these figures also, the

portions

19 and 20 are at a level lower than that of the remaining parts of the

protective members

15, 16, respectively.

What is claimed is:

1. A shaving head construction for a dry shaver comprising a mounting plate provided with an integral edgelike protective member, at least two spaced cutting lates mounted in said mounting plate, said protective member being located at a higher plane than the remainder of said mounting plate, said protective member having a portion thereof extending into the space between said cutting plates.

2. A shaving head construction for a dry shaver comprising a mounting plate provided with an integral ridgelike protective member, at least two spaced cutting plates mounted in said mounting plate, said protective member being located at a higher plane than the remainder of said mounting plate, said protective member having a portion thereof extending between the cutting plates and completely filling up said space therebetween.

3, A shaving head construction for a dry shaver comprising a mounting plate provided with an integral ridgelike protective member, at least two spaced cutting plates mounted in said mounting plate, said protective member being located at a higher plane than the remainder of said mounting plate, said protective member having a portion thereof extending into the space between said cutting plates, said portion of said protective member extending into the space between the cutting plates being located on a plane lower than said ridge-like protective member but higher than the level of said mounting plate.

4. A shaving head construction for a dry shaver comprising a mounting plate provided with integral rib portions located at a higher plane than the remainder of the mounting plate, two circular spaced cutting plates located below said rib portions but above the remainder of said mounting plate, and at least a substantial part of said rib portions being located between said circular cutting plates.

Claims

1.
