The invention relates to a hand-operated dry shaver consisting of a base body with several inclined blades, over which an elastic perforated band slides, and with side parts that accommodate the perforated strip in guide elements, as well as with at least one housing part for receiving of the various elements.

It's already a hand-operated dry shaver with a massive, stretching over the entire Width of the same extending, divided or undivided body known. Inside the main body slots are provided for inserting the blades. In the known dry shaver are for the blades either special holding elements are required, or the insertion slots must be located Extend the full width of the blades. This will facilitate the cleaning and replacement of the Sounding difficult. In addition, the insertion slots that extend over the entire width of the blade must can be manufactured with high accuracy.

The object of the invention is such a design of a dry shaving device of the type mentioned that the cleaning and the replacement of the blades can be done easily that the insert elements for the blades can be produced in a simple manner and that during the production of the base body Savings can be achieved.

This object is achieved according to the invention by a base body made of two injection molded parts, firmly adhering in pairs on their side faces facing each other in the assembled state lug studs or sleeves that can be pressed into one another and on the respective opposite side surfaces Have collar sections which engage in corresponding recesses in the side parts.

The injection molded parts of the base body can be designed as hollow bodies so that they are easy to manufacture and require only a comparatively small amount of material. Inside the body halves there are slots for inserting the blades. The blades are on two in this construction Places held and can be easily removed and replaced. The dry shaver is overall easy to disassemble, so that it is convenient to use even in practical use.

From the drawing, which is an exploded view of the various components of a dry shaver according to the invention reproduces, for example, as well as from the description are others Details and advantages of the invention can be found.

In the illustrated embodiment, there is the hand-operated dry shaver

Base body of two block-like injection molded parts 1, 2 made of plastic, which are connected to one another with interlocking shoulder bolts or shoulder sleeves 9, 10 or 11, 12 by sufficient frictional engagement. The injection-molded part 2 has outer shoulder bolts 3, 4 which each terminate in a cylindrical collar section 7, 8 at their ends, and is also provided with slots 18, 19, 20, 21 and 22 . The other injection-molded part 1 also has outer shoulder bolts which, corresponding to the outer shoulder bolts 3, 4 of the injection-molded part 2, each terminate in a cylindrical collar section (in the drawing, only one outer shoulder bolt 5 of the injection-molded part 1 corresponding to the shoulder bolt 4 of the injection-molded part 2 is visible). In the injection molded part 1, slots 13, 14, 15, 16 and 17 are also introduced in a corresponding manner.

Disc-shaped side parts 25, 26 of the base body are made of metal and are on their circumference beaded to form guide flanges 27, 28 and with circular recesses 33, 34 and 35, 36 provided, which with their edge portions 37, 38 and 39, 40 are slightly recessed towards the interior of the housing are. Furthermore, the side parts 25, 26 have circular recesses 29, 30 and are dome-shaped Convulsions 31, 32 are provided.

The plastic lower case 50, the inner shape of which is the shape of the lower portion the side parts 25, 26 is adapted, carries to a small extent protruding lugs 51, 52 with cylindrical Scope 53 or 54. The housing cover 55 is made of plastic and is with

its inner shape of the shape of the upper portion of the side parts 25, 26 adapted. On the housing cover 55 projecting lugs 56, 57 are formed in the shape of a dome. Also blades are 60, 61, 62, 63 and 64 provided, which form cutting edges 70, 71, 72, 73 and 74 on one longitudinal side.

Furthermore, a perforated strip 80 made of thin, elastic steel is provided, which passes through on both sides parallel longitudinal edges 81, 82 and at the joint ends on both sides through to the vertical with respect to the Longitudinal edges 81, 82 slightly inclined transverse edges 83, 84 is limited.

To assemble the shaver, the shoulder bolts 9, 10 of the injection molded part 2 are in the Extension sleeves 11, 12 of the injection molded part 1 inserted. Then the blades 60 to 64 are in the Slots 13, 18 or 14, 19 or 15, 20 or 16, 21 or 17, 22, which are each arranged in alignment, used.

Now the perforated strip 80 is assembled around the previously assembled Arrangement placed, in such a way that the transverse edge 83 is seen from the outside over the transverse edge 84 (this winding direction is in shown in the drawing). The side panels 25, 26 are then attached, with the collar portions 7, 8 of the injection molded part 2 and the corresponding collar sections of the outer shoulder bolts 5 of the injection molded part 1 into the recesses 33, 34 of the side part 25 or into the recesses 35, 36 of the side part 26 engage. The long edges 81.82 of the perforated strip 80 now engage under the beaded guide flanges 27, 28 of the side parts 25, 26 and are thus covered by these guide flanges 27, 28. The parts thus assembled will be inserted into the lower housing 50, the lugs 51, 52 in the recesses 29, 30 of the elastic Engage flexible side parts 25, 26. The housing cover is then removed in a corresponding manner 55 placed, the lugs 56, 57 latching into the bulges 31, 32 of the side parts 25, 26.

The entire device now forms a completely closed housing. The housing cover is used for use 55 removed by a light pull and the shaver can be used immediately. The user puts the device with the perforated tape 80 tightly on the skin and leaves it with the under Perforated tape 80 arranged blades 60 to 64 slide over the skin; these blades cut the hair or stubble, which through the numerous openings of the perforated strip 80 in the area of the blades enter. After use, the housing cover is just as easily put back in its place. Starting from the illustrated embodiment, it would be conceivable as a further development that in Lower housing 50 and in the housing cover 55 ventilation holes are provided, which at the same time contribute to weight loss.
