Definitions

the invention relates to a shaving head for dry shavers with the features specified in the preamble of the main claim.
Shaving head constructions of this type which are known for example from DE-OS 28 43 657, have the advantage that they can be easily disassembled and reassembled for cleaning and replacing damaged or worn shaving foils, even by laymen and inexperienced users, without that the sensitive shaving foil is exposed to the risk of damage.
the interchangeable frame and the mounting of the shaving foil thereon can be produced in one injection molding process, so that additional operations are unnecessary.
the invention has the object to ensure with a shaving head of the type mentioned that the shaving foil can easily follow the yielding movement of the lower knife under shaving pressure, but remains tied against entrainment by the working movement of the lower knife, and that The shaving foil together with the removable frame can be easily removed at any time.
the holder and guidance of the interchangeable frame in the shaving head frame according to the invention can be implemented in various ways.
a particularly advantageous embodiment is given with the features of claim 2.
the arrangement and design of the tabs allows the elasticity to be varied from the longitudinal sides of the frame to the tabs according to their separate functions by the choice of the material thickness, and to set a desired friction between the surfaces of the tabs and the sides of the shaving head frame by selecting the pressure and the coefficient of friction , which can dampen vibrations.
Further advantageous and expedient special features for the further development of the invention can be found in subclaims 3 to 7.
the shaving head for dry shavers shown in Fig. 1 consists essentially of a shaving head frame 1 of conventional design, which is detachably placed on the apparatus housing 2.
a circumferentially closed, box-shaped interchangeable frame 3 can be used, which consists of a limited elastic material in which a shaving foil 4 is arched.
This shaving foil 4 interacts with a lower knife 5 ground according to its curvature, which is pressed into the curvature of the shaving foil 4 by a spring 6 and is set into a reciprocating movement by a motor (not shown) via a rocker arm 7.
the removable frame 3 shown in FIG. 3 in its removed state and without a shaving foil has two transverse sides 8 and 9 and two longitudinal sides 10 and 11, on the lower edges of which tabs 12 and 13 are formed somewhat offset inwards. These tabs are elastic and in the rest position shown in FIG. 3 are set at a small angle to the outside.
a part of the mounting and guiding means for the interchangeable frame 3 in the shaving head frame 1 are attached in the form of openings 14 into which, as another part of the mounting and guiding means, hook-shaped projections 15, which on the associated inner surfaces 16 of the Shaving head frame 1 are provided to intervene.
the fits between the openings and projections are selected in part as a narrow sliding fit, which only allows vertical movement but no significant movement in the working direction of the lower knife, while for the yielding movement of removable frames and shaving foil in or against the arrow direction A, a clearance fit corresponding to this movement stroke is provided, as shown in Fig. 1.
the mounting and guide means can of course also be interchanged, ie the projections 15.1 are on the tabs 12, 13 and the openings 14.1 on the inner surfaces 16 of the shaving head frame 1.
the height of the openings 14 and 14 ' is slightly larger than that possible way of the lower knife 5 under shaving pressure ie opposite to the direction of arrow A and the selected displacement path B between the changing frame 3 and the shaving head frame 1, which is limited at the bottom by placing the lower edge of the changing frame on the upper edge of the shaving head frame.
Above the transverse sides 8, 9 of the interchangeable frame 3 rise end cheeks 17, 18 which are provided with sliding knobs 21 on their outer surfaces facing the end cheeks 19, 20 of the shaving head frame 1.
the distance between the end cheeks 17, 18 of the interchangeable frame from each other has a certain excess compared to the corresponding distance between the end cheeks 19, 20 of the shaving head frame 1, so that the end cheek pairs 17 - 19 and 18 - 20 abut against one another with a slight tension via the sliding knobs 21.
the shaving foil 4 is fastened to the long sides 10 and 11 of the interchangeable frame, in this case generally rigid, for example by welding or extrusion coating.
the interchangeable frame 3 or 3.1 is deformed inward by pressure on its long sides 10, 11 so that it can be inserted with its tabs 12, 13 into the shaving head frame 1, 1.1, 1.2 from above until the holding means snap into place .
the tabs 12, 13 engage behind the associated inner surfaces 16 of the shaving head frame and rest there with slight tension.
the interchangeable frame together with the clamped-in single or multiple-curved shaving foil and it with this cooperating bottom knife arrangement can yield to the inside of the housing without the shaving foil bulging out and the contact area between the two shear parts being reduced.
the corresponding surfaces of the interchangeable frame which bear against the walls of the shaving head frame with slight tension ensure that the displacement movement takes place with a certain amount of friction, with which fluttering and vibrations of the interchangeable frame are largely eliminated.
the additional construction effort is low, so that economical production is also ensured.
