Description

GERMAN

The invention relates to a dry razor cutting head. It can be a removable cutting head for or on a Trodcen shaver or a hinged cutting head on a Be a dry shaver, the cutting head having a cutting plate which can be fixed in it in a rigid position and a cutting member to be driven, which is arranged behind it and which is secured by a closure member is included to avoid falling out.

In known dry shavers with removable or hinged cutting head are used for Attachment of the cutting plate and for enclosing the knife used different means, wherein a movable plate is used to enclose the cutting member and can be displaced into such a position is that the cutting member comes free and is removable from the cutting head.

To that extent, according to another known embodiment, one and the same means for fastening the cutting plate and should serve to enclose the knife, it is a different design, namely one in which the cutting insert and cutting link are firmly connected to one another by means of screws are, so the cutting member is not free to move, and only on the latter type of construction with a freely movable cutting member, the invention refers.

According to the invention is used both to attach the cutting plate and to include the Cutting member one and the same means, so that there is a simplification of the design.

According to a further characteristic of the invention, the closure member is arranged so that it can be opened, that the cutting plate and the cutting member are easily removable together.

In order to avoid that in a dry shaver with more than one cutting insert the associated Cutting members are exchanged, which is undesirable because the cutting member and the associated Cutting plate are ground on each other, the cutting plates each have a closure member of this type mutual arrangement that by opening the one closure member, the other closure members be blocked.

The construction according to the invention can be realized in a simple manner when the closure member consists of a U-shaped spring, the legs of which rest against the cutting plate and upright behind one standing edge of the cutting head are resiliently enclosed, the connecting piece between the legs are attached to the cutting head in an articulated manner.

The invention is illustrated with reference to an example of a cutting head for removal from a

or to open on one

Cutting head according to the invention illustrated drawing.

Fig. 1 is a bottom plan view of a cutting head according to the invention, and

Fig. 2 shows a cross section along the line II-II according to Fig. 1.

In the figures, a cutting head consists of a plate 1 with openings in which cutting plates 2 and 3 are arranged. The cutting members which cooperate with them are located behind these cutting plates 4 and 5. U-shaped springs 6 and 7 are pivotable with their connecting piece 8 and 9 on the Plate 1 attached. The spring 7 is shown in its operative position in which the legs 10 and 11 on the Insert the cutting plate 3 and at the same time enclose the cutting member 5. The ends of the legs 10 and 11, which are resiliently movable in the direction of the arrow shown, are upright behind you standing edge 12 of the cutting head included.

The spring 6 is shown in a partially unfolded state. When this spring is further folded to the right is, as is shown in FIG. 2, the cutting insert 2 with the associated cutting member 4 can easily be lifted out of the opening in plate 1. The position of the spring 6 prevents in completely unfolded state, the unfolding of the spring 7.

The shape of the connecting pieces 8 and 9 is slightly curved. These connecting pieces can also be used participate in securing the cutting link in the plate. This also results in the possibility that despite the very small distance between the cutting tips 2 and 3 through by folding down one of the springs, the associated cutting plate can be completely freed.
