Abstract

A dry shaver includes at least one shaving blade which is arranged in a pivotable head frame closed on its sides and which cooperates with cutters oscillating in the longitudinal direction of the shaving blades. The head frame is detachably connected with a base part which includes a cutter driving mechanism. The head frame is designed in two parts, wherein an outer head part carrying the shaving blade(s) is pivotally connected with a part of the head frame that is detachably fixed to the base part, the pivotal connection being about an approximately central pivot axis extending transverse to the oscillation direction of the cutters.

Claims

1. A dry shaver of the type having at least one shaving blade which is arranged in a pivotable head frame which is closed on its sides, the shaving blade cooperating with cutters oscillating in a longitudinal direction of the shaving blade and the head frame being detachable connected with a base part which supports a driving mechanism for oscillating the cutters, the improvement comprising the head frame being formed by a first head part which carriers the shaving blade and which is pivotally joined to a second head part which detachably connects the head frame to the base part, said pivotal joinder of the first and second head parts being about a pivot axis which is substantially centrally located in the head frame and which extends transverse to the longitudinal oscillating direction of the cutters.

2. A dry shaver according to claim 1, wherein sealing surfaces are provided between the first and second head parts.

3. A dry shaver according to claim 1 or 2, further comprising a cutter-carrying block pivotally connected to the driving mechanism about an axis which, together with the pivot axis of the first and second parts, lie in a longitudinal center plane of the base part.

4. A dry shaver according to claim 1 or 2, further comprising stops provided on the second head part to limit the pivotability of the first head part relative to the second head part.

5. A dry shaver according to claim 3, further comprising stops provided on the second head part to limit the pivotability of the first head part relative to the second head part.

6. A dry shaver according to claim 1 or 2, further comprising at least one spring interposed between the first head part and the base part.

7. A dry shaver according to claim 3, further comprising at least one spring interposed between the first head part and the base part.

8. A dry shaver according to claim 4, further comprising at least one spring interposed between the first head part and the base part.

9. A dry shaver according to claim 5, further comprising at least one spring interposed between the first head part and the base part.
