Description

DETAILED DESCRIPTION OF THE INVENTION The invention comprises a cutter head crimped to a cutterfoil by a crimping spring, said crimping spring being supported on the one hand in a component connected to the cutter head and on the other hand in a spring receiver. The present invention relates to electric dry levers in which the spring receiver is provided on a swinging lever that drives a canter head. Electric dry levers of this type are commonly used and are known (German Patent No. 1,110,045).

In order to be able to shave the hair, the cutter head of the electric dry shaper must be in sufficient contact with the cutter foil at all times. For this purpose, a pressure spring supported on a swinging spring support presses the cutter head onto the upper cutter foil. However, this crimping force required for shaving inevitably creates friction between the cutter foil and the cutter head, a phenomenon that is itself disadvantageous because it Abrasion occurs between the cutter foil and the cutter foil.
Moreover, this friction increases the amount of energy consumed to drive the electric Dry Sieno ζ. This is a drawback, especially in dry levers that are operated by batteries.

Experience has shown that depending on the hardness and thickness of the hair to be trimmed, the pressure of the cutter head against the cutter foil must be of different strengths. This has not been taken into account in conventional electric dryers; rather, the compression spring is capable of effectively shaving hair that comes through the cutter foil hole even under unfavorable conditions. It was always designed to be possible.

The object of the present invention is to provide an electric dryer lever, which takes the type of electric dryer of the type mentioned at the beginning as a prior art, and is capable of adjusting the pressing force of the cutter head against the cutter foil in accordance with various shaving conditions. This problem was solved in the electric dry scienor ζ of the type mentioned at the outset, in that the spring holder has a plate, the height of which can be adjusted manually.

The advantages of the invention are manifold. Firstly, the present invention makes it possible to easily adjust the pressing force of the cutter head against the cutter foil.

This allows the user to shave smoothly,
Moreover, the crimping force can be reduced by the individual user so that the crimping force between the cutter head and the cutter foil is as small as possible. By reducing friction in areas absolutely necessary for shaving, wear on the cutter foil and cutter head is reduced.
In addition, this reduces the noise generation and tendency of the electric dry shaper to vibrate, which is considerably less compared to known electric dry shapers. In addition, the energy consumption of the electric dry lever etc. is reduced. This is of particular importance for battery operated dry systems.

In an advantageous embodiment of the invention, the spring catch is adjustable in stages. With this configuration, the position of each spring catcher is therefore reproducible at any time. For example, if three locking positions are provided, a first position for drying, for example with a long hair clipper, a second position for shaving the beard, and a third position for shaving the beard. The embodiment according to claim 3 is structurally extremely simple and can be provided for shaving other body hair.

If a locking cam is provided on the conical outer surface of the swing lever, the spring support plate that supports the compression spring can be easily centered by the swing lever. Adjusting the plate can be carried out in a simple manner thanks to the advantageous embodiment of the invention as defined in claim 5.

Numerous possible embodiments of the invention are possible. One of these is shown in the drawing, with reference to which the invention will now be described in detail.

An electric P-frame 2 is mounted on the upper part of the casing 1 of the electric P-Raicieno partially shown in FIG. A cutter foil 3 is stretched in a curved manner within the cutter head frame 2. A swinging lever protrudes from the casing 1 and is reciprocated by a motor (not shown), and this swinging lever drives the cutter head 5. The cutter head 5 is crimped onto the cutter foil 3 by a crimping spring 6. Second
As shown in Fig. 3, the connecting member 7 is attached to the swinging lever.
is fitted over the connecting member 7, and the canterhead 5 is fixed to this connecting member 7 in a well-known manner. The connecting member 7 can be moved downwards in the drawing against the force of the compression spring 6. The compression spring 6 is supported on the one hand by a connecting member 7 and on the other hand by a spring receiver 8 provided on the swing lever -Φ.

The spring holder 8 essentially consists of a spring holder 9. This spring receiving plate 9 swings in the illustrated position and S
It is placed on the collar 10 of 4. Since the spring receiver has a knurling 11 attached to the outer periphery of the plate 9, the spring receiver can rotate the plate 9 without using a tool.

Instead of the knurling 110, a radially arranged knob may be provided on the outer periphery of the spring receiving plate 9. By rotating the spring receiver plate 9, the spring receiver plate 9 swings as seen in FIGS. 2 and 3 and moves upwards on the ζ-cow.

This is important to the invention and will be discussed in more detail below. When the plate 9 of the spring receiver moves upward, the pressing force of the pressing spring 6 against the connecting member 7 is increased, so that the cutter spatula 15 is strongly pressed to varying degrees against the cutter foil 3 of the electric dry knife.

It is clear from the other drawings how the swinging lever 4 and the spring support constitute the plate 9, since the spring support converts the rotation of the plate 9 into an axial movement.

Figures 4, 5 and 6 show the upper end of the swinging lever cowl. This rocker S 4 has a conical section 12 on the upper side of the collar 10 , the upper region of which is designed as a locking cam 13 . The exact shape of the locking cam 13 can be most easily seen in FIG. FIG. 7 shows the locking cam 13 being swung and expanded parallel to the central axis of -Φ. The locking cam 13 is 18
It consists of two identical sections extending over 0°.

Each section has a total of three locking positions 14, 15, 16 or 14', 15 formed in a V-shape at different heights.
', 16'.

As shown in Figures 8, 9, and 10, the spring receiver is
has two opposing keys 18, 19 in the chi-ξ hole 17. The spring receiver plate 9 is locked at the locking position 14, 15, 16 or 14', 15', 16' with this key 18.19.
can be located in In the basic position, the spring receiver plate 9 is located in the locking position 14, 14' with the keys 18+, 19. When the spring receiver plate 9 is rotated, the spring receiver plate 9 is lifted in accordance with the inclination of the locking cam 13, and the keys 18, 19 are locked in the tenth locking position 15, 15'.

By further rotating the plate 9, the spring holder will release the key 1.
8.19 reaches the locking position 16, 16' provided at a higher level than the locking position, and when further rotated, returns to the initial locking position 14, 14' again. Individual locking positions 1'4, l5.

16 as well as 14', 15' and 16' are of deep design, so that the spring retainers remain in these locking positions 14°, 15, 16 unless the plate 9 is rotated further by hand.
They also remain at 14', l'5', and 16'.
