Definitions
- the invention relates to a long-hair cutting device for dry shavers with a shaving comb fixedly arranged on a shaving head frame and a shaving blade which can be moved back and forth in a straight line along the latter and is pressed against it by means of pressure springs, consisting of a blade blade and a rigid support body.
- a general problem with long-hair trimmer parts is to provide blade blades that are produced by galvanic or etching technology.
- Blade blades that are produced by this process have a number of advantages, in particular in the better cutting performance, which is due to the optimal design of the cutting edges and compliance with the cutting angle, and the cheaper production by eliminating production processes compared to blade blades, which Stamping processes were produced can be seen.
- the latter must be stamped, embossed, hardened and ground. Apart from the necessary use of machine tools and tools that are subject to wear and have to be maintained constantly, this manufacturing process cannot achieve perfect cutting edges and cutting angles on the blade blades.
- CH-PS 480 922 discloses a pivotable long hair cutting device with a fixed shaving comb and an oscillating thin, angled, resilient blade, which is embedded in a support body. Resilient blade blades of this shape cannot be produced by galvanic or etching technology and therefore do not have the optimal cutting edges and cutting angles of the blade blades produced by these methods.
- US Pat. No. 3,909,938 shows a pivotable long hair cutting device with a blade blade which is embedded or riveted in a support body.
- the support body is movably mounted on a stationary bearing rod.
- the blade blade protruding relatively far from the supporting body projects into a U-shaped, resilient shear comb. Twists of the blade blade protruding from the supporting body are absorbed by the U-shaped shaving comb surrounding the blade blade, but the blade blade lies. This means that at times it does not touch the active cutting edge, which means that threaded hair is not cut in this area, but rather torn off or squeezed out.
- DE-PS 20 19 978 shows a long hair cutting device consisting of a punched shaving comb and a punched blade blade, the fixed shaving comb being fastened to a supporting body and the oscillating, rigid blade blade being pressed against the shaving comb by means of pressure springs provided between the supporting body and the blade blade.
- the rigid blade blade having an angular profile is attached to a reciprocating support body, the attachment being carried out via the bolts shown so that the pressure springs acting directly on the blade blade vertically can move to rest on the fixed shear comb.
- the bolts shown merely prevent the blade blade from moving laterally on the support body.
- None of the known long hair cutting devices shown above is suitable for the direct use of a galvanically or etched manufactured due to their particular constructive design, which can be seen in particular in the shape or the required elastic properties of the blade or the type of pressure of the pressure springs on the blade Blade blade.
- the object of the present invention is to provide a long-hair cutting device of the generic type which permits the use of galvanically or etched blade blades in order to take advantage of the advantages mentioned above, which such blade blades bring with them.
- the blade is flat and is firmly attached to the support body, at least the teeth with their entire The cutting area protrude beyond the support body, that the blade and the support body form a rigid unit, and that the pressure springs are supported on the one hand on a support bar provided on the shaving head frame and on the other hand they rest on the support body.
- the support body which preferably consists of a molded plastic part with molded knobs which engage in corresponding recesses in the blade blade, the rigidity of the support body is transferred to the thin blade blade, such that the blade blade forms a rigid unit with the support body .
- This rigid unit created according to the invention enables the use of galvanically or etched blade blades and the exploitation of the advantages that these blade blades bring with them.
- the rigid unit allows sliding surfaces to be provided on the fixed side of the blade blade of the blade blade to reduce the friction of the surfaces sliding against each other.
- the oscillating movement of the drive lever is transmitted via a drive bolt to a fork designed as a coupling element, which can be integrally formed on the supporting body or on the blade blade and causes the structural unit to oscillate in the operating state.
- recesses for receiving pressure springs are provided in the support body.
- these recesses facilitate the assembly of the support body with the pressure springs in the shaving head frame, on the other hand, they define the position and the pressure point of the pressure springs in order to achieve a pressure of the shaving blade that is uniformly distributed over the entire width of the structural unit on the shaving comb.
- the position of the shaving blade and thus that of the support body is determined on three sides and secured by the support via the pressure springs on the support strip on the housing wall of the shaving head frame, by the system on the housing wall of the shaving head frame and by the contact of the blade blade attached to the support body on Shear comb.
- the shear blade or the supporting body is slidably held in the intended position by means of one or more guide strips. These guide strips are preferably part of the shaving head frame or are attached to the inner wall thereof.
- the shaving head frame of a dry shaver is denoted by 1, the housing wall shown in section by 2 and the front cheek by 3.
- a support strip 4 extending in the longitudinal direction is formed on the inner wall of the housing wall 2.
- the long-hair cutting device has a fixed shaving comb 5, a movable shaving blade, consisting of a blade 6 and a support body 7, and pressure springs 8, which are supported on the support bar 4, and a fork 9 formed on the support body 7.
- the long hair cutting device is shown in the operating state.
- the displaceable drive lever 10 is located above the integrally formed drive bolt 11 in the U-shaped recess of the fork 9 and in this way transmits the oscillating movement of the drive lever 10 which is in the switched-on state to the movable shear blade.
- the drive lever 10 By moving the drive lever 10 in the direction of arrow B, the drive pin 11 slides out of the fork 9, whereby the long-hair cutting device comes to a standstill.
- the shaving foil 12 is held in the shaving head frame 1 in a known manner, while the fixed shaving comb 5 is fastened by two screws or rivets 13 on a ledge 14 provided on the shaving head frame i.
- the housing wall 2 of the shaving head frame ends just below the movable blade blade 6, so that here a narrow gap 27 is formed through which the blade blade 6 and partially the support body 7 are visible over the entire width.
- the partial breakthrough made in the housing wall 2 indicates the drive lever 10 with the drive bolt 11, the fork 9, the support body 7, two pressure springs 8 and a guide bar 15, insofar as these are exposed by the partial opening.
- the pressure springs 8 are supported on the support bar 4 shown in dashed lines in FIG. 2, which is located on the inside of the housing wall 2 of the shaving head frame, and protrude with its opposite end into recesses 16 on the support body 7. These recesses 16 define the position and the pressure point of the pressure springs 8 in the support body 7 and are also used for Guiding and facilitating the assembly of these mutually engaged components.
- four recesses 16 are provided in the support body 7 and four pressure springs 8 in the long-hair cutting device shown.
- a guide bar 15 is visible, the task of which is to hold the support body 7 in its sliding position, i.e. to prevent movement or migration of the support body 7 in the direction of arrow A according to FIG. 1.
- the partial opening shows, starting from the center line, only the right side of the support body 7 with the guide bar 15 and two pressure springs 8. It goes without saying that * the left side is mirror-inverted.
- a groove 17 is provided on the support body 7, in which there is a knob 18 for holding the blade blade 6.
- FIG. 1 Two further knobs 19 and 20, which are used to fasten the blade blade 6 on the support body 7, are shown in FIG.
- the three-point fastening shown has proven to be sufficient and ideal for blade blades produced by electroplating or etching. However, a two-point or more than three-point attachment can also be provided.
- the shape of the knobs 18, 19, 20 can be the same or different z. B. square, and / or rectangular and / or round.
- the receiving openings 21, 22 and 23 are to be provided in the blade block 6, the knobs and receiving openings interlocking with one another without play.
- the blade blade 6 is pressed against the support body 7 via the knobs and rests with its entire back against the support body.
- the blade blade 6 has sliding surfaces 24 and 25 on the side facing away from the supporting body 7. Only these sliding surfaces 25 and 25 slide on the fixed shear comb 5.
- the sliding surface 24 consists of a narrow web, while the sliding surface 25 is made wider beyond the tooth depth of the teeth 26 of the blade blade 6 around the receiving openings 21, 22 and 23.
- the material thickness of the blade blade 6 is slightly thinner in the area between the sliding surfaces 24 and 25. This is by produced galvanically or by etching Klingenblä t ter due to the process without additional effort feasible.
- FIG 4 shows the shear blade consisting of the support body 7 and the blade 6 of Figure 3 in the section C-C specified there.
- the blade 6 pushed on and held by the knobs 18 lies flat on the support body 7.
- the blade blade 6 is made stronger in the area of the sliding surfaces 24 and 25.
- the support body 7 consists of a plastic injection-molded part on which the visible knobs 18, the other knobs 19 and 20 described, and the fork 9 are integrally formed as a coupling element.
- the fork 9 can also be integrally formed on the blade blade 6.
- the teeth 26 of the blade blade 6 protrude at least with their entire cutting area beyond the outer contour of the support body 7.
