Description

Long Hair Cutter for Dry Shaver The present invention eoneerns a long hair cutter for dry having a stationary cutting comb and a serrated cutting blade designed for and fro movement in relation to the said blade being springily urged to the Such ments are usually provided on dry shavers in addition to the shaving head short hair cutter The long hair cutters serve for outting long trimming the and trimming contours at the temples the A satisfactory cutting effect is obtained only both elements of the the comb and the blade are uniformly pressed against one another throughout their whole In the conventional assembly of the where individual parts are fixed to the casing singly and one after the other and are connected by screws or the desideratum of uniform pressure conditions between and blade of the long hair cutter can not always be Especially in the case of screw connection which pass tirough the it is unavoidable that unequal stresses act on different parts of the deforming the It is an object of this invention to provide a long hair cutter which can easily be mounted on the shaver and which is free of above This can be according to the invention by that the cutting comb and the cutting blade together with a carrying body are assembled to form an operational unit which as such is adapted to be affixed to the casing of the the said body being provided guide elements for the blade for the The formation of the longhair cutter with a separate carrying body forming a unit to be attached to the shaver permits testing thereof after the liminary assembly of the such tests being in no way by the remaining parts of Advantageously the means for affixing the unit to the casing of the shaver should be below the plane of the cutting parts and substantially parallel to that In this way the comb remains free of harmful tension which could be caused by clamping According to another advantageous executional form of the invention the cutting comb is affixed to the carrier by means of a the means for affixing being below and substantial parallel to the plane of the This also warrants absence of tension at the comb and facilitates the According to yet another feature the guide elements areforraed by stays extending upwardly from the carrier body and passing through elongated apertures in the cutting These stays may be embedded into the carrier as separate parts or may be fixed thereto a releasable Where the carrier body is of plasti it preferable to have the stays moulded in one with the In order to avoid theblade assumes an oblique the stays have a bulbous head in the range ef the said elongated These bulbous heads aay be formed of separate parts or may be moulded in one the Between the free ends of the springs urging comb blade together and the underside of the blade there is provided according to the a glide strip of low whereby tension is obviated also in the blade and a satisfactory pressure urging comb and blade is in the absence of undue The annexed drawing shows an executions1 form of by way of There are shown in 1 a cross section through a shaver head of a dry shaver in 2 a frontalview ef the long hair cutter unit 3 is a section on line of 2 is a section on line of 2 5 shows a variant of a detail according to On the upper part 1 ef the casing of a dry shaver there is placed a frame 2 open at top for the perforated foil which is affixed in the conventional way bp means of the casing extends upwardly the oscillating lever of a motor which is accommodated in the At the end 6 of the said lever there is held movably the blade block 7 which is urged against the foil 3 by means of a spring one side of an aperture 9 the frame 2 there is accommodated a hair cutter which is shown in detail in and which is indicated by the numeral This cutter consists mainly of a stationary comb 11 and a serrated cutting blade 12 in a plane below the The blade is driven to perform a and fro an arm 14 engaging a fork 13 which is functionally nected with the The arm Ik is oscillated by the lever The cutter assembly also a canrying body 15 which has By means of a flange 16 set off the comb and extending over the whole width of the cutter the 11 is affixed to the carrier by means of two rivets 17 somewhat below and in parallel to the plane of the parts 11 and At the side which is directed towards the cutter parts 11 and 12 there are formed two stays 18 and 19 on the carrier they may also be set in the body of the carrier as indicated in 5 which stays extend through elongated holes in the cutting blade and guide the latter in its cutting Zn order to avoid a jamming of the stays in the apertures 20 the stays may have a bulbous as shown in 5 this example the stay shank 18 is set in the carrying body Moreover recesses 23 provided serving as Abutments for three pressure Between the free ends of springs 26 and the underside of theblade 12 there is provided a glide strip 27 made of low friction an appropriate synthetic This ensures a uniform and frietionless application of the blade onto the For the proper orientation of the strip on the springs there are provided knobs Instead of the shown spiral there may be used also a longitudinal leaf While at front the teeth 11 and 12a respectively of the comb and the blade are urged against one at the rear there are several bosses 12b on the upper side of the blade The complete long hair cutter shown in 2 to is integral unit which can be assembled tested before being mounted on the shaver and may be attached to the shaver by means of the screw bolts and 33 in a flange 16 and which at the same time hold the foi insufficientOCRQuality
