■ Shaving head for dry shavers' -.

The innovation '"relates to a shaving head for dry razors j using a leaf spring attached to the lower blade.

There are shear heads for dry shavers ₉ "in which the lower blade is a leaf spring which is slidably connected at one end fixed and the other end of the lower blade, known" When attaching the shaving head on the Trockenrasiergerät a Antriebssohwenkhebel engages a center of the leaf spring mounted articulated a _s presses the spring with the lower knife against the upper knife and is thereby brought about during the entire back and forth movement while working. In order to avoid the lower knife falling out of the shaving head, shoulders are attached to the leaf spring when the shaving head is removed, ie *. when the drive pivot lever is removed from the bend of the spring, it automatically locks into a slot of a support connected to the upper knife, thereby causing automatic centering of the lower knife against the upper knife _o The holder the leaf spring in the lower blade happens because the leaf spring on each En de is bent at right angles against the lower knife, whereby one end of the leaf spring is fixed in a slot of the lower knife without play, and the other T-shaped end is slidably inserted in a bayonet slot of the lower knife.

However, shaving heads of this type have different ones To show deficiency "

Is it recorded after a certain period of time? that the right angle bent end of the spring _S which slidably in the bayonet slot of the lower blade j runs on the flanks worn is ₅ breaks down and is not given a continuous pressing of the üntermessers to the upper blade more "Due to the one side of the lower knife not with the same strong in engagement projecting spring is out of significantly reduced cutting performance of the Trockenrasiergerätes a very loud noise, the sequence * the same wear phenomena, j only to a lesser extent the spring _s partially can lead to breakage of the spring to the fixedly clamped in the lower blade square ended and ^ available * the production of the spring _s particular end with the relatively weak turns their recording, resulting in increased Committee "Furthermore, as part of Mach found that the contact surfaces of the spring are very small compared to the lower _blade? as a result, wear and tear and, after a long period of use of the dry shaver, the correct pressure of the lower blade against the upper blade is no longer guaranteed «

The purpose to be achieved by the innovation ■ shallj- is the elimination of the deficiency which is caused by

the leaf springs that have been used up to now are available * ■

The innovation is based on the task of a shaving head to create "," in which the work process is continuous Pressure of the lower knife against the upper knife is given via a leaf spring, and which is designed so that it largely eliminates the risk of breakage and signs of wear and tear.

According to the innovation, the object was achieved in that the leaf spring has two acute-angled _{tabs bent towards the ends of the leaf spring ZU 5} , which when the shaving head is removed and the drive lever is removed from the bend of the leaf spring ₃ with the tabs in the opening of the retaining plate intervene automatically ^ form a safeguard against the lower blade falling out of the shaving head and centering when the shaving head is placed back on the dry shaver housing in the drive pivot lever via the guide bevels attached to the leaf spring on both sides of the bend and ■ the leaf spring has a rounding at its ends in the contact direction to the lower ridge and one end of the leaf spring with a slot in the acute-angled bent lobes of the lower blade with ge toroidal game and the other -. The end of the leaf spring engages in a known manner with a bayonet slot in the other right-angled T-shaped end of the lower blade gMtend and the leaf spring is tapered in the area between the acute-angled lobes «--..-.

The technical and economic effects of the innovation are the use of a. Leaf spring, which largely avoids the risk of breakage _{} has} low levels of rejects in production and therefore has little cause in terms of buyers: there are complaints «

The innovation will be explained in more detail below using an exemplary embodiment * in the associated Show drawing;

On the dry shaver housing 1 is the shaving head 2 _? consisting of the upper blade 3 with cohesively attached retaining plate _4-9 removed with base plate 3 $ shark Tewinkel 6 and the lower blade 7, with the leaf spring 8 is made "aufgebracht- on the lateral retaining springs 9 :, For attachment of the leaf spring 8 on the lower knife 7

serve two at the end of the lower knife 7 Torhandene loops; H _{3 of} which one is bent at an acute angle and the other is bent at right angles and the latter has a T-shape. The leaf spring 8 is designed _{3 in} such a way that it has two acute angled tabs 12 at the end of the guide s diagonally 13 j and openings at the ends are available, one as a rectangular slot 14 and the other as a bayonet slot 15 ", In its center, the leaf spring 8 has a bend 16 and at its ends a rounding 17 on the sides of the bent tabs 12 _o For fastening the leaf spring 8 the same is inserted with its rectangular slot 14 into the acute-angled bent lobes Io of the lower blade 7 with little play and the bayonet slot 15 is slid into the right-angled T-shaped lobe 11 of the lower blade 7 Opening 18 of the lower blade 7 a _# The roundings 17 at the ends of the leaf spring 8 are used to $ the frictional resistance to keep as low as possible during the work process and by greatly reducing the relatively large contact surface wear and tear move freely over the holding plate * After reaching the opening 19 in the holding plate 4, the leaf spring 8 springs back automatically and prevents the tabs 12 bent at an acute angle to the holding plate 4 from falling out of the leaf spring 8 from the shaving head 2 "-

The pressing out of the lower blade T ₉ in the shaving head 2 removed from the dry razor housing 1 takes place in turn by pressing the leaf spring 8 against the lower blade 7 via the recess 2o in the base plate 5 and the opening 19 in the holding plate 4 *. -

The automatic centering of the drive lever when placing the shaving head 2 in the leaf spring 8 is given by the guide bevels 13 on the leaf spring 8 * The leaf spring is used to achieve a soft suspension tapered in the area between the acute-angled flaps *
