Description

In the proposed hair clipper with a replaceable pair of hair cut combs, the head with a pair of hair cut combs or the combs alone can be rearranged either on the hand fists or replaced with a head with different number combs, without using any tools and without removing screws, nuts, etc.

In FIG. 1 depicts the type of machine above; FIG. 2 is a section along the line AB in FIG. one; FIG. 3 - side view of the machine; FIG. 4 is a side view of a machine arranged for a mechanical drive; FIG. 5 and a b-top view of the head and the machine shown in FIG. 4, with a snapshot.

The fixed left handle / (FIGS. 1 -3) is equipped with rectangular cams 1 and a trunnion f - the axis of rotation of the right movable handle m, with the opening / serving as a nest for a known return spring with a threaded spring sleeve; the support sheet / provided with a hole for a screw pin G on which the right hand grip is fitted with a working cam T For guiding the upper movable comb p the box n is equipped with two spikes n and a long edge of the bottom ridge o installed movably on the spikes p, “Fastened with a box of combs with a screw and a nut on the top comb p there are two prominent rectangular studs, between which a working cam t of the movable handle t and two notches are placed, whose side surfaces serve as controls or limiters combs. The box n and both combs and and o can be shifted from the right angle knuckles (left hand grip) and the last, e turn turned over to their original position. Thus, the supporting surface can be either the lower thickness of the comb o, or the upper thin movable comb p, which results in different shearing heights.

The box n can be fixedly mounted; then attracted to each other cheeks to ILR / T. The comb device can be turned around and the sleeves secured in the box with the aid of a fastening screw with a nut or other fastening device.

In a modified mechanically driven hair clipper (Fig. 4-6), on the handle 2 there are two pins 3.3 for inserting the head with holes 14.14, bolt 4 for strengthening the movable lever 10, hole 5 for inserting the drive screw into it 23, slit-shaped groove 6 for the room

In it, an adjusting sleeve 25 and a slot 7 with beveled side surfaces 8. The pins 3 are side-mounted with hemispheric recesses 9 for fixing the head, Lever 10, which can be rotated on the bolt 4, is provided with a break 11. In go; 14, the lower comb 15 and the upper 16 lie, pressed against each other by a fastening screw 17 with a padded leaf spring 18 and a nut 19 (Fig. 4). Upper comb 16 has a recess 35, with the edges of which contact the fork 11 of the movable lever 10. In the two openings of the head 13 two screws 20, two springs 21 and two lock balls 22 are placed; when the pins 3 are pushed into the holes 14, the balls 22 lie in the hemispherical pins 9 of the pins, as a result of which a spring connection is obtained. The worm 23 is driven into rotation around the axis 34 by the worm gear 31, while the finger 32 eccentrically mounted on the wheel 31, through the quadrilateral sleeve 33, causes the double-arm lever 10 to oscillate. The knurled adjusting nut 25 passes into the slit-shaped groove 6 of the handle. The axis of the screw is inserted into the sleeve, with the screw-pin 26 of the sleeve entering with its end into the corresponding recess on the screw-shaft, as a result of which the sleeve rotates simultaneously with the screw. Being partially covered, the adjusting nut 25 does not touch the fingers of the wick; The era, while the oval slot 7 with beveled surfaces makes it possible to turn the nut 25 and the screw to 23, which allows the lever 10 to be turned and placed in the position required for the head attachment. The connective hemispherical sleeve 27 (Fig. 4) is held in its position by a spring connection; A sleeve 28 is mounted on this sleeve, in which a flexible shaft 29 rotates with a gap, leading to

rotation, through the rod 30, the worm to 23. The side surfaces of the upper comb 16 can protrude beyond the head, which, with sufficient rounding of the protrusions, allows the head to slide on the fork 11 of the lever 10; at the same time, the tip of the pins 3 should be tapered to make it easier to insert the ends of the fork 11 of the movable lever 10 into the groove 35 of the comb.

The subject of the patent.

1. A hair clipper with a replaceable pair of cutting combs, characterized in that the box n, which together with the combs / and o, movably fastened with screw n, the machine head, is provided with cheeks, and the handle / -cles I - /, intended to be fixed on them with the help of cheeks to, worn with friction, a machine head, which device is used to allow the head to be replaced with another head with combs of a different number or to replace the comb head p in place of the supporting comb (Fig. 1- 3) ..

2. The change of the hair clipper described in paragraph 1, characterized in that when the machine is mechanically driven, the head of the machine for fitting it onto the pins j, 3 of the handle .2 is provided with openings 14,14, and for fastening the head with the handle Known spring closures are applied (Fig. 4-6).

3. An embodiment of a hair clipper according to claim 2, characterized by using a recess with rounded edges in the head of the machine, designed to accommodate a reciprocating movement of the fork 11 of the lever 10 that informs the shearing comb (FIG. 4-6).
