BACKGROUND OF THE INVENTION v through apertures provided in a shear foil, with a long hair trimmer having an elongated movable clipping blade extending along one edge of the shear foil. As a rule, the head frame of the shaver is separable from the main housing of the shaver and is attachable thereto in two positions in one of which the clipping blade of the trimmer, which latter is permanently installed in the head frame, is coupled to the drive for the cutter. Thus,

whenever the operator wishes to use the trimmer, the

head frame must first be'detached from the housing and thereupon reattached to the housing in a different position. Furthermore, the trimmer which is permanently installed in the head frame extends well beyond the shear foil so that it reduces the accessibility of the adjacent portions of the shear foil, i.e., certain portions of the shear foil cannot beplaced sufficiently close to the skin to permit satisfactory cutting of bristles by the corresponding portions of knives on the movable cutter.

.It is further known to mount the long hair trimmer in such a way that it can be coupled to or detached from the drive for the movable cutter behind the shear foil without necessitating a change in the position of the head frame. To this end, the electric shaver comprises a specially designed coupling element which shares all reciprocatory movements of the cutter or the movements of the output member in the drive for the cutter. An electric motor which can drive the output member so as to reciprocate the cutter and the movable clipping blade of the long hair trimmer is disclosed in the British Pat; No. 68 I ,333. Such electric shavers still exhibit the drawback that the trimmer invariably projects well be yond the outline of the head frame and thus interferes withproper use of all portions of the shear foil. Also,

the outwardly extending trimmer adversely affects the appearance of theshaver and necessitates the use of complicated cases or containers wherein the cutter is stored when not in use.

SUMMARY OF THE INVENTION I It is an object of the present invention to provide in a power shaver, especially an electric dry shaver, 'a

novel and improved long hair trimmer which does not .or nearly fully concealed and protected when it is not in use, to thus reduce the overall dimensions and to enhance the appearance of the shaver as well as to avoid damage to component parts of the trimmer.

It is an additional object of the invention to provide an elongated hair trimmer for a power shaver which is composed of relatively few and simple parts so that it can be manufactured at reasonable cost and will stand up properly under extended use.

With these and other objects in view, which will become apparent as the description proceeds, the present invention relates to an elongated hair trimmer mounted on the housing of a power shaver and comprising a supporting member, a stationary clipping member fixed to the supporting member, a movable clipping member reciprocable relative to the supporting member and cooperating with the stationary clipping member, and clamping means for biasing the movable clipping member against the stationary clipping member. Mounting means are further provided for mounting the elongated hair trimmer pivotable about a tilting axis extending substantially parallel to the direction of elongation of the hair trimmer for tilting the latter between an opera tive position projecting in part outwardly beyond the outer surface of. the housing and an inoperative position substantially concealed in the housing. i

The stationary clipping member preferably is fixed to one side of the supporting member and the movable clipping member is arranged on the other side reciprocable in longitudinal direction of the supporting member relative thereto. The supporting member and the movable clipping member are provided with cooperating means for guiding the movable clipping member during its reciprocating movememt relative to the supporting member and for limiting such movement. These cooperating means may comprise at least one elongated guide slot in one of the two members which are movable relative to each other and a guide rail projecting in the guide slot and arranged on the other of these two members. The clamping means'is preferably in the form of a substantially U-shaped resilient spring partially encompassing and pressing the clipping members against each other.

The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The improved power shaver itself, however, both as to its construction and its mode of operation, together with additional features and advantages thereof, will be best understood upon perusal of the following detailed description of certain specific embodiments with reference to the accompanying drawing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS shown in FIGS. 18 and 19. The drive means which is operable to reciprocate the cutter M along the concave internal surface of the shear foil S includes an output I member 1 which is oscillatable or rotatable by an electric motor (not shown) in the main portion of the housing G in a manner not forming part of the present invention.

When properly mounted in the head frame 3, the shear foil S resembles a trough which overlies and is closely adjacent to the knives K. Two exposed longitudinal edge portions 51 (one shown in FIG. 17) of the shear foil S extend in parallelism with the longitudinal directionof the cutter M, and the illustrated edge portion S1 is adjacent to and parallel with an elongated long hair trimmer 2. In accordance with a feature ofthe invention, the trimmer 2 is pivotably mounted in the head frame 3 of the housing G for movement between an inoperative or concealed position shown in FIG. 2 and operative or exposed position shown in FIG. 3. The mountingmeans (best shown in FIG. 1) which serves to pivotably support the trimmer 2 in the head frame 3 defines for the trimmer a pivot axis which is preferably parallel to the adjacent exposed edge portion S1 of the foil comb S. In accordance with another advantageous feature of the invention, the movable clipping or trimming element or clipping member 9 (shown in FIGS. 12 and 13) of the trimmer 2 is automatically coupled with the preferably oscillatory output member 1 of the drive for the cutter M when the trimmer is pivoted to the operative position of FIG. 3 so that the movable clipping element 9 cooperates with a stationary clipping or trimming element or clipping member 4 of the trimmer 2 as soon as the motor in the housing G is started by closing a suitable switch, not shown. The motor can be driven by an expendable energy source in the housing G, by a rechargeable energy source in the housing and/or by electric current supplied by a suitable outlet by way of a cable of cord, not shown.

The long hair trimmer 2 is preferably assembled into a discrete unit which is thereupon mounted in the head frame 3. FIGS. 6 and 7 show the trimmer 2 in fully assembled condition but detached from the head frame 3, and FIGS. 8m 15 illustrate the four components of the trimmer 2 drawn to approximately twice their normal size.

FIGS. 8 and 9 show the stationary clipping element 4 of the trimmer 2. This clipping element 4 has an elongated rear end portion or holder 5 provided with three equidistant circular-openings 6 for reception of preferably elastic projections or pins 8 provided on an elongated supporting member or carrier 7 shown in FIGS. 10 and 11. The rear portion or holder 5 is provided with a row of forwardly extending teeth 5a which can cooperate with similar teeth 9a provided on the elongated movable clipping element 9 which is best shown in FIGS. 12 and 13. The supporting member or carrier 7 preferably consists of a single piece of suitable synthetic plastic material and its projections 8 are preferably deformed (see FIG. 3) to form rivet heads which hold the rear portion 5 of the stationary clipping element 4 against any and all movements with reference to the carrier. However, it is equally within the purview of the invention to provide the carrier 7 with cylindrical projections 8 which completely fill the respective openings 6 to thus hold the clipping element 4 against lenthwise and/or sidewise movements with reference to the carrier. The means for holding the clipping elements 4 and 9 against movements away from the adjacent surfaces of the carrier 7 comprises an elastic clamping member or clip 15 shown in FIGS. 14 and 15.

The carrier 7 is provided with guide means which permit the clipping element 9 to move back and forth lengthwise of the clipping element 4 whereby the teeth 5a cooperate with the teeth 9a to sever the hair which penetrate through the spaces between the teeth 9a and into the spaces between the teeth 9a and into the spaces between the teeth 5a.

The movable clipping element 9 has two elongated slots 10 of constant width which are open at their outer ends, namely, at the end faces 11 of the clipping element 9. The carrier 7 has two elongated guide rails 12 each of which extends into one of the slots 10. The distance between the guide rails 12 and the distance between the slots 10 determine the extent to which the clipping element 9 can reciprocate with reference to the carrier 7. The clipping element 9 is further guided by the clipping element 4 because the row of teeth 9a abuts against the row of teeth 5a when the long hair trimmer 2 is fully assembled in a manner as best shown in FIGS. 2-4 and 6-7. Furthermore, the rearmost portion 9b of the clipping element 9 is bent substantially at right angles to the main body portion and abuts against a similarly bent flange 5b of the rear portion 5 as well as against the adjacent surfaceof the carrier 7 to thereby further insure that the clipping element 9 is confined to lengthwise oscillatory movements.

The aforementioned clamping member or clip 15 overlies the major part of the movable clipping element 9 but leaves the teeth 9a exposed. The clip 15 is elastic and substantially U-shaped so as to confine the

parts

4, 7, 9 (see FIGS. 2-4 and 6-7) and to thus hold the clipping elements 4, 9 against movement away from the carrier 7. The bias of the clip 15 suff ces to insure that the slots of the clipping element 9 cannot move away from registry with the guide rails 12, Le, that the clipping element 9 is confined to reciprocatory movements in its own plane even though it is not positively secured to the carrier 7. The flanges of the U-shaped clip have inwardly bent tips or

prongs

15a, 15b (see particularly FIG. 15) which bear against the adjacent portions of exposed surfaces on the clipping elements 4 and 9 (see FIGS. 6 and 7) and follow the outlines of such surfaces.

Those portions of the clipping elements 4, 9 which are immediately adjacent to the respective teeth 5a, 9a together form a body of substantially V-shaped crosssectional outline (see FIGS. 2-4 and 7). The

prongs

15a, 15b bear against such portions of the elements 4, 9 to thus insure thet the row of teeth 9a is biased against the row of teeth 5a. The

prongs

15a, 15b further serve to prevent accidental separation of the clip 15 from the

parts

4, 7 and 9 because they must be forcibly spread apart in order to provide room for separation of the clip from the clipping elements 4 and 9. As shown in FIGS. 2-4 and 7., the combined width of the

parts

4, 7, 9 in the region 16(FIG. 6) of the bent-over portions 5b, 9b substantially exceeds the normal distance between the

prongs

15a, 15b.

The mounting means for the trimmer 2 is installed in the head frome 3 of the housing G and comprises registering axially

movable trunnions

20, 21 which extend into blind bores or sockets 18 (FIG. 11) provided in the end faces of the carrier 7. The bores 18 are preferably tapped and the

trunnions

20, 21 are preferably provided with external threads to mesh with the carrier 7. The latter is further formed with hook-shaped abutments 23 (FIGS. 1, 10, 11) which are adjacent to the sockets l8 and remote from the teeth 5a, 9a. The abutments 23 are formed with grooves 24 for the

end portions

25a, 25b of a substantially V-shaped spring 25 (see particularly FIG. The grooves 24 are disposed at one side of the common axis of the sockets 18 (see FIG. 11). The end portions a, 25b of the spring 25 bear against the abutments 23 and the median portion 250 of this spring reacts against the head frame 3 so that the spring 25 biases the carrier 7 in a counterclockwise direction, as viewed in FIGS. 2-4 and 11, to thereby urge the trimmer 2 (when the latter is properly mounted in the head frame 3) to the operative or extended position of FIG. 3. The median portion 250 of the spring 25 is flanked by two short connecting portions 25d and the

end portions

25a, 25b make in the unstressed conditions of the spring 25 an obtuse angle alpha which preferably substantially exteeds 90. The angle alpha is normally between 130 and l60.

The head frame 3 is provided with pairsof stops and 31 which serve to arrest the trimmerZ in its operative and inoperative positions. These stops cooperate with the abutments 23 on the carrier 7. The stops 31 engage the abutments 23 in the inoperative position of the trimmer 2 (FIG. 2) and the stops 30 are engaged by the abutments 23 when the trimmer 2 dwells in the operative position of FIG. 3. The positions of the stops 31 are best shown in FIGS. 4 (side elevation), 5 (front elevation) and 1 (top plan view). The stops 30 limit the extent of pivotal movement of the trimmer 2 under the action of the spring 25. With reference to FIGS. 2-4, the trimmer 2 turns about the common axis of the

trunnions

20, 21 in a counterclockwise direction to advance toward its operative position under theaction of the spring 25, and in a clockwise direction in order to stress the spring 25 while returning to the inoperative or concealed position of FIG. 2. During clipping of long hairs, the trimmer 2 (in the operative position of FIG. 3) is moved downwardly so that the teeth 5a of the stationary clipping element 4 slide along the skin and the abutments 23 bear against the stops 30 of the head frame 3. Since the forces which tend to pivot the trimmer 2 from the position of FIG. 3 back to the position of FIG. 2 are not likely to develop when the trimmer is in use, the spring 25 suffices to normally insure proper retention of the trimmer in its operative position. The user must apply finger pressure to pivot the trimmer 2 against the opposition of the spring 25 when the trimmer is to be returned from the operative position of FIG. 3 to the inoperative position of FIG. 2. At the end of such pivoting of the trimmer 2 about the common axis of the

trunnions

20 and 21, the trimmer performs a relatively small lengthwise movement in the axial direction of the trunnions (see the distance a in FIG. 1). Such lengthwise movement of the trimmer 2 takes place in a direction toward a depressible releasing member or knob 32 which is mounted in the head frame 3 and is to be shifted in a direction to the right, as viewed in FIG. 1, to release the trimmer 2 to the action of the spring 25 which is then free to pivot the trimmer to the operative position of FIG. 3. During manual pivoting of the trimmer 2 against the opposition of the spring 25 the abutments 23 or the carrier 7 move toward and are ultimately shifted sideways to abut against the stops 31 in the head frame 3."The abutments 23 and the stops 31 then constitute a simple latch which holds the trimmer 2 in the operative position and can be disengaged in response to depression of the knob 32.

FIGS. 1 and 5 shown that the

stops

30 and 31 are slightly offset with reference to each other. This allows for lengthwise movements of the trimmer 2 through a distance at least approximating the distance a shown in FIG. 1. Such lengthwise movement of the trimmer 2 takes place in response to depression of the knob 32 (arrow Pfl in FIG. I). The stops 30 are provided in recesses or cutouts 35 machined into a side wall or cheek 36 of the head frame 3. Each recess 35 is of rectangular outline, as seen from the interior of the frame 3. That surface bounding each recess 35 which is nearest to the main portion of the housing G constitutes the respective stop 30. The length of each stop 30 slightly exceeds the corresponding dimension of the respective abutment 23 so that the abutments 23 are free to move in the respective recesses 35 toward and away from the associated stops 30. Such movements take place under the action of the spring 25 upon depression of the knob 32 which then moves the abutments 23 away from alignment with the stops 31 so that the spring 25 is free to pivot the trimmer 2.

The, side wall 36 of the frame 3 is provided with an aperture 40 for a coupling finger or motion receiving finger 41 of the movable clipping element 9. The central portion of the aperture 40 has an extension 43 which accommodates the coupling finger 41 in the inoperative position of the trimmer 2. The extension 43 has an open side which faces the adjacent portion of the shear foil S. A second extension 44 of the aperture 40 in the wall 36 of the head frame 3 is adjacent to the extension 43 (see FIG. 2) and serves to receive the me dian portion 250 of the spring 25. The median portion 25c including the connecting portions 25d of the spring 25 is U-shaped (see FIG. 20) and can be held in the extension 44 with at least some friction.

That portion of the side wall 36 which normally conceals the trimmer 2 (FIG. 2) is bounded by a slightly convex surface 46. This surface enables the user to utilize the entire exposed part of the shear foil S, i.e., also that part which is adjacent to the edge portion S1 and to the trimmer 2 when the latter is held in the inoperative position of FIG. 2.

As shown in FIG. 1, the trunnion 21 of the mounting means for the trimmer 2 is biased by resilient means, here shown as a relatively strong helical spring 47, which urges the trimmer 2 in a direction toward the release knob 32. The outer end convolution of the spring 47 bears against a plate-like retainer 48 which is secured to the head frame 3 by a screw 49 or an analogous fastener. A cover 50 which consists of synthetic plastic material overlaps the plate 48 and the head of screw 49 and is recessed into the adjacent portion of the frame 3. The cover 50 has a deformable connecting portion 51 which can be received in a recess 52 of the plate 48 by snap action.

The cover 50 is adjacent to that end of the trimmer 2 which is remote from the release knob 32. The latter is rigidly connected with the trunnion 20 so that the trunnion 20 moves the trimmer 2 at least through the distance a when the release knob 32 is depressed in a direction toward the cover 50. Such lengthwise displacement of the trimmer 2 against the opposition of the spring 47 suffices to move the abutments 23 out of registry with the stops 31 so that the spring 25 is free to pivot the trimmer 2 to the operative position of FIG. 3 in which the abutments 23 engage the stops 30 in the recesses 35 of the side wall 36. The release knob 32 consists of a single piece of synthetic plastic material and has an exposed handgrip portion 52 of circular outline and an eccentric sleeve 53 (see also FIG. 16) which has a bore 54 for a cylindrical extension 55 of the trunnion 20. The sleeve 53 is received in a bore 59 of the head frame 3 and the extension 55 has a circumferential groove 58 for a ring-shaped portion 56 of the sleeve 53. The portion 56 couples the trunnion 20 to the release knob 32. This portion 56 can be formed whele the sleeve 53 is in a deformable state.

As a rule, the trimmer 2 must be tested prior to mounting in the head frame 3. Therefore, it is desirable to assemble the trimmer in the manner as shown in FIGS. 6-7, i.e., as a self-sustaining unit which can be readily tested prior to mounting in the head frame 3. The testing involves cutting of hairs in order to determine whether or not the

parts

4, 7, 9, 15 are properly assembled so that the teeth a, 9a are ready to cut long hairs. The

parts

4, 7, 9, must be finished with a certain (preferably high) degree of precision because any substantial deviations from proper size or shape might affect the operativeness of the assembled trimmer.

Another advantage of the trimmer 2 is that it occupies little room so that the dimensions of the head frame 3 need not be unduly increased in order to provide room for concealment of the

parts

4, 7, 9, 15 in the inoperative position of the trimmer. The cost of the trimmer 2 is reasonable because that part (carrier 7) which has the most complicated configuration can be mass-produced from synthetic plastic material, e.g., by an injection molding process. The clipping element 4 (or the clipping element 9) preferably consists of stainless steel or a like metallic material and the element 9 is freely slidable in the longitudinal direction of the carrier 7 to the extent determined by the slots 10 and guide rails 12. The projections 8 can be simply forced into the openings 6 of the clipping element 4 to hold the latter against lengthwise and sidewise movements with reference to the carrier 7, or such projections can be deformed with or without heating to hold the element 4 also against a movement away from the adjacent surface of the carrier 7. In FIGS. 1-5, all such surfaces of the carrier 7 which are not shown in section are indicated by stipling.

When the user decides to trim long hairs, e.g., the sideburns, the release knob 32 is depressed to shift the trimmer 2 through the distance a and to thus disengage the abutments 23 on the carrier 7 from the stops 31. The spring 25 pivots the trimmer until the abutments 23 reach the stops 30. At such time, the finger 41 of the movable clipping element 9 is withdrawn from the extension 43 of the aperture 40 in the side wall 36 and engages with a coupling portion 61 of the output member 1. The coupling portion 61 has an inlet 62 which is flanked by inclined surfaces 63 (see FIGS. 1-4) which enable the finger 41 to properly engage the coupling portion 61 even when the latter is in motion, i.e., while the output member 1 reciprocates the knife M along the internal surface of the shear foil S. Analogously, the finger 41 can be returned into the extension 43 while the output member 1 is in motion, simply by pivoting the trimmer 2 from the operative position of FIG. 3 to the inoperative position of FIG. 2. The entire exposed surface of the shear foil S is then available for the shaving operation.

FIG. 5 shows the spring 25, the abutments 23 and the knob 32 in solid lines (operative position of the trimmer 2) and in broken lines (inoperative position of the trimmer). When the trimmer 2 is pivoted to the inoperative position, the spring 47 is free to expand and moves the trimmer lengthwise so that the abutments 23 engage the stops 31, whereupon the stops 31 maintain the trimmer in the inoperative position as long as the release knob 32 remains in the position shown in FIG. 1.

As shown in FIGS. 2-4, the shear foil S overlies the exposed side of the aperture 40 so that it must be provided with a cutout or slot (not shown) for the coupling finger 41. However, it is equally within the purview of the invention to shorten the shear foil S or to mount it in the head frame 3 at a level above the aperture 40, as viewed in FIGS. 2-4, so that the shear foil need not be weakened by the provision of a cutout or slot for the finger 41. For example, and referring to FIG. 2, the lower edge portion of the shear foil S can terminate at a level above the extension 43 of the aperture 40 so that the shear foil, even without a cutout therein, cannot interfere with movements of the finger 41 into and from motion receiving engagement with the coupling portion 61 of the output member 1 of the drive means for the knife M. Such mounting of the shear foil S would add little to the length or bulk of the shaver.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can,

by applying current knowledge, readily adapt it for various applications without omitting features which fairly constitute essential characteristics of the generic and specific aspects of my contribution to the art and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the claims.
