Definitions

  • the invention relates to a hair clipper according to the preamble of claim 1.
  • Such a hair clipper is known for example from DE-OS 1 553 760.
  • This hair clipper has a cutting set which consists of a shaving comb and a shaving knife which can be driven oscillating essentially parallel to the front edge of the shaving comb, that is to say in the transverse direction.
  • the shear knife has a fork into which a driver of the drive motor engages.
  • a cutting length adjustment device which enables a relative displacement between the shaving comb and the shaving knife in the longitudinal direction. It has an actuating element in the form of a lever which is articulated on the housing of the hair clipper and via a
  • Coupling element allows manipulation of the shear knife.
  • the lever allows the cutting length to be adjusted even during the actual cutting process, which is why such hair clippers are particularly popular in professional use.
  • a cutting length adjusting device is integrated in the cutting set.
  • the actuation is carried out via actuating elements attached directly to the cutting set, such as a knurled wheel or a swivel lever, which, however, do not permit ergonomically advantageous actuation of the cutting length adjustment during the operation of the hair clipper.
  • the cutting length adjustment device is therefore mainly suitable for presetting a certain cutting length, and is therefore comparable to the cutting set described above.
  • the present invention was therefore based on the problem of improving a hair clipper of the type mentioned at the outset in such a way that it no longer has the disadvantages described.
  • a hair clipper should be created that is structurally simple and allows optimal operation of the cutting length adjusting device, even when the machine is running. This problem is solved with a hair clipper having the features of claim 1.
  • Advantageous embodiments are given by the features of the subclaims.
  • the invention is based on the idea of exchangeably guiding the cutting set on the housing and combining the fixing element on the housing side with the cutting length adjusting device.
  • the fixing function on the one hand and the adjustment function on the other hand are combined in a single assembly, so that the structural design can be considerably simplified.
  • the coupling element acting on the cutting set is provided with a receptacle in which a pin is axially displaceably mounted.
  • the pin is aligned with a corresponding locking hole in the shear comb, in which it engages in a fixing manner.
  • the cutting set is slidably received over the shaving comb along a guide attached to the housing, which makes it particularly easy to replace.
  • the leadership also ensures that the shear comb with respect to its relative position in relation to the
  • Housing is precisely aligned and is slidably supported by the pin in the intended adjustment range.
  • the shear knife is provided with a driver opening into which the driver of the drive motor is brought into engagement.
  • the relative position between the shaving knife and the housing with respect to the longitudinal direction is predetermined, so that the cutting length can be adjusted by moving the shaving comb over the coupling element. If the locking hole completely penetrates the shear comb, the pin can be actuated directly from the outside. This makes it particularly easy to replace the cutting set, since the pin can be pressed out of the engagement area. The cutting set can then be easily moved along the guide. '
  • a spring acting between the pin and the receptacle is preferably provided, which presses the pin into the latching bore.
  • the spring is particularly preferred due to its compact construction.
  • the pin is preferably provided with an axially acting stop, which specifies the maximum displacement in the direction of the latching bore.
  • an axially acting stop which specifies the maximum displacement in the direction of the latching bore.
  • the receptacle preferably has an elongated hole which extends in the transverse direction and in which the pin is displaceably mounted. In this way it is ensured that the pin is always guided precisely and without lateral forces in the latching bore, regardless of the current position of the actuating element.
  • the actuating element is pivotally mounted eccentrically with respect to the longitudinal axis of the cutting set, which results in different points of attack. These can be compensated for by the elongated hole.
  • the engagement of the pin in the locking hole when opening ben of the cutting set facilitates, since even in the event of a slight lateral offset between the pin and the locking hole, a compensating movement can take place.
  • a further advantageous variant can be seen in which the driver is attached to the drive motor by means of a leaf spring. It allows the driver to retreat, so that when the cutting set is changed it can slide out of the driver opening or dip into it without the need for direct actuation of the driver.
  • the hair clipper can be provided with a cutting length adjusting device which has a mechanism for the gradual relative displacement between the shaving comb and the shaving knife.
  • a rocker arranged substantially transversely to the longitudinal direction, at one end of which a lever is fastened, while the other end has at least one first latching row into which at least one latching lug of a locking spring can be brought into engagement.
  • the locking spring is fork-shaped, at least one latching lug of one leg can be brought into engagement with the at least one latching row, while the other leg can be supported on a housing of the hair clipper.
  • the other end of the locking spring is preferably provided with a release button, by the actuation of which the locking lug or locking lugs of the locking spring can be released from the engagement with the locking rows.
  • Figure 1 is a hair clipper in longitudinal section, basic structure.
  • Figure 2 is a partial perspective view of the cutting set fully attached to a housing.

  • corresponding parts are provided with the same reference number.
  • FIGS. 1 and 7 The basic structure of a hair clipper 10 with a cutting length adjustment device 14 results in particular from FIGS. 1 and 7.
  • a drive motor 60 is inserted, which, via a driver 56, has a shear knife 18 provided with a driver opening 19 in the transverse direction, means, in a plane perpendicular to the cutting plane shown, drives oscillating.
  • the cutter 18 is directed against a Scherka m 16, so that a cutting set 12 is formed.
  • the cutting set 12 is designed to be exchangeable, that is to say it is detachably connected to the housing 42.
  • the cutting length adjusting device 14 has an actuating element 20 in the form of a lever, which is articulated on the housing 42 in the manner which will be explained in more detail below and protrudes therefrom.
  • the lever 20 is flexibly connected to a Schwige 36.
  • the rocker 36 is pivotally mounted on the housing 42 via a bearing pin 38, so that actuation of the lever 20 leads to a rotational movement of the rocker 36 around the bearing pin 38.
  • the rocker 36 has a receptacle 24 with an elongated hole 25 extending in the transverse direction. In the elongated hole 25, a pin 22 is inserted in such a way that it along the
  • Elongated hole 25 in the receptacle 24 is guided so that it can be displaced essentially without force.
  • a spring 46 is inserted, which presses the pin 22 axially outwards.
  • a stop 23 specifies the maximum displacement of the pin 22 with respect to the receptacle 24.

  • This therefore not only serves to hold the cutting set 12 on the housing via the shear comb 16, but also enables the shear comb 18 to be displaced within the limits which are predetermined by the travel path of the pin 22.
  • the shear knife 18 is fixed in terms of its position in the longitudinal direction by the driver 56, as a result of which the cutting length can be adjusted by shifting the shear comb 16. Since the driver 56 is connected to the motor 60 via a leaf spring 58, the driver 56 can slide out of the guide opening 19 when the cutting set 12 is pushed out of the guide 64, or can engage in the latter as soon as the cutting set 12 is pushed on.
  • the surface of the housing 42 which essentially corresponds to the outwardly facing surface of the cutting set 12 can be provided with a recess 66 in the region of the end section of the cutting set 12 which faces the housing 42.
  • This depression 66 makes it easier to push out the cutting set 12 after the pin 22 has been depressed, since the operator along this depression 66 with a finger, e.g. B. the thumb, the cutting set 12 can slide away from the housing 42.
  • the new shaving knife 18 is first put on until the driver 56 engages in the driver opening 19.
  • the pin 22 is then pressed down against the force of the spring 46.

  • this rocker 36 in this case has first and second locking rows 26 and 28. These two locking rows 26 and 28 are arranged one above the other on a gap.
  • First and second locking lugs 30 and 32 of a locking spring 34 can alternately engage in the first and second locking rows 26 and 28.
  • the locking spring 34 is fork-shaped at one end, one leg, which in this case has two leg types. me, is provided with the first and second locking lugs 30 and 32, while the other leg can be supported on the housing 42.
