Definitions

  • the present invention relates to an adjustment device for a hair clipper according to the preamble of claim 1.
  • Hair cutting devices in which the cutting effect is achieved by moving blades back and forth have been known for a long time.
  • the distance in a set of blades i.e. the distance between a movable cutting part (blade) and a stationary cutting part (comb)
  • a hair clipper with a movable blade and a stationary blade i.e. a blade that is fixed to the hair clipper and cannot be moved in the horizontal and/or vertical direction
  • the movable blade moves laterally relative to the stationary blade when the hair clipper is actuated back and forth.
  • the movable and stationary blades are adjustable relative to each other in a direction perpendicular to a reciprocating direction of movement. Also, in a hair clipper having two movable blades, these blades reciprocate relative to each other and can be adjusted in a direction perpendicular to a reciprocating direction.
  • the distance between the two hair cutting parts is adjusted by loosening fastening elements with a tool by hand and before using the hair cutting device.
  • the fasteners are typically screws located on a lower portion of the clipper that connect the movable blade to a guide held by the stationary blade. Complete loosening or loosening of the screws sets the blades to the desired spacing. After adjusting the distance, the screws must be tight enough so that they cannot loosen when the hair clipper is subsequently used.
  • the teeth of the moving blade are typically offset from the teeth of the stationary blade to avoid cutting the skin of an animal or a person whose hair or beard is being trimmed.
  • the movable blade should be adjusted before the cutting process so that it is offset a very small distance from the stationary blade.
  • the object of the present invention is therefore to provide an adjustment device for a hair clipping device that enables a user to set the cutting sets to a maximum short distance from one another in a simple and reproducible manner, so that a maximum short cut length can be achieved safely and with the least possible effort while minimizing the risk of skin injury.
  • this object is achieved by an adjustment device for a hair-cutting device having the features of claim 1 .
  • the upper, movable cutting set part is referred to below as the “cutting blade” and the larger lower cutting set part is referred to as the “cutting comb” or simply “comb”.
  • the combination of shearing blade and shearing comb with any attachments is referred to as a "cutting set”.
  • the device without the cutting set is referred to as "hair clipping device”.
  • the "knife-comb distance" to be adjusted with the adjusting device according to the invention is referred to as the distance from the cutting comb tooth tip to the cutting knife tooth tip.
  • the "cut length” is the shortest distance from the tip of the shearing blade to the bevel of the shearing comb.
  • the knife is geometrically constrained by a so-called “linear guide” between the shearing knife and the guide piece.
  • the knife-to-comb spacing and parallelism are unchanged in the on and off states.
  • the shearing knife moves in a circular arc.
  • the knife-to-comb distance and the parallelism in the on and off states change continuously.
  • the blade In the off state, the blade is always on the right or on the left side due to the force applied inside the housing of the hair clipper.
  • a hair-cutting device has a device housing and a blade set that is firmly connected to the device housing.
  • the cutting set consists of a clipping blade, which includes blade tips, and a clipping comb connected thereto, which includes comb tips.
  • the clipping comb is detachably connected to the clipping blade and thus also to the hair clipping device by means of connecting elements such as screws.
  • the adjusting device according to the invention for such a hair clipping device is characterized in that it is dimensioned in such a way that it can accommodate and hold the shaving comb, so that the shaving comb can be moved relative to the device housing together with the adjusting device after loosening or partial loosening of the connecting elements that a distance between the knife tips and the comb tips can be defined.
  • the device according to the invention thus enables the knife tips and the comb tips to be adjusted to a maximum short distance from one another without having to dismantle and remove the entire cutting set from the device housing for the adjustment.
  • the risk of injuries that the operator can inflict when removing the shearing blade is significantly minimized.
  • the distance is adjusted in a simple but nevertheless precise manner, so that a maximum short cutting length can be realized with as little work as possible.
  • a so-called zero-overlap setting can thus be carried out very precisely using the setting device according to the invention, without this setting depending on the skill and experience of the user.
  • the shaving comb preferably rests in a defined manner with the comb tips on the adjustment device, which is dimensioned accordingly in order to securely receive and hold the shaving comb so that the adjustment can be carried out.
