Definitions

  • the present invention relates to a beard trimmer, more commonly referred to by the English term “trimmer”, comprising a mechanism for suspending the cutting unit making it possible to dampen the contact between the trimmer and the skin, in order to provide a better feeling for the user but also a better cutting result.
  • Beard trimmers include a handle as well as a motorized cutting unit.
  • the cutting unit comprises a fixed blade and a movable blade, and can also be provided with a comb in order to adjust the desired cutting length.
  • the user encounters many different bends on the face when trimming the beard, especially on the chin area, and the quality of the cut largely depends on the maneuverability of the trimmer.
  • the document WO2005122685 discloses a clipper with a cutting head and a comb arranged on a handle so as to be simultaneously movable relative to the handle, while maintaining a constant distance between the cutting unit and the comb so as not to influence the length of chopped off.
  • the cutting unit and the comb recoil and reduce the pressure acting on the skin.
  • the motor is also movable and set in motion with the cutting unit and the comb.
  • This is located in the handle and is connected to the cutting unit by a "motion converter", allowing the pressure on the cutting unit to be transmitted to the motor, the latter pushing on a spring provided in the handle in order to to cushion movements on the skin.
  • This device improves the feeling of cutting and also avoids friction of the skin by too much pressure.
  • This device has the disadvantage of comprising a set of moving parts external to the handle, arranged in such a way as to make the mower cumbersome and difficult to handle, especially in tight spaces. In addition, this trimmer is easily clogged and difficult to clean.
  • the present invention aims to provide a beard trimmer that does not have the disadvantages of the state of the art, namely the large size, the difficulty of maneuverability and easy clogging. It aims in particular to provide a beard trimmer with improved comfort of use thanks to its ease of handling.
  • An object of the invention is to provide a mower with a system for suspending the cutting unit, allowing a better quality cut thanks to the suspension system which corrects the differences in pressure exerted on the skin, which can lead to differences of lengths. Thanks to the almost constant pressure applied to the skin, the cut is improved.
  • the suspension system also limits skin friction and unpleasant sensations related to changes in pressure on the skin.
  • Another objective is to provide a mower with a simplified arrangement of the various elements of the suspension system compared in particular with the mowers of the state of the art.
  • the aim is to have all the moving parts of the suspension system located inside the handle, avoiding clogging and the difficulty of cleaning as well as the complexity of manufacture. In this way, the design of the handle is also simplified and more ergonomic.
  • the cutting unit is as compact as possible, to respect the morphological constraints of the face in order to work at the level of the mustache for example and the movements of the cutting head easily follow the curves of the face.
  • the present invention discloses a beard trimmer 1 with a handle 2 and a motorized cutting unit 3.
  • the motorized cutting unit as shown in the Figure 2 , includes a cutting head 5 and a motor 4 (see on the Figure 4 ).
  • the cutting unit is fixed on a mobile unit 6 of substantially cylindrical shape, sliding in a complementary substantially cylindrical shape located inside the handle, thereby allowing the movement of the motorized cutting unit.
  • the mobile unit constitutes a shell encompassing the motor and part of the cutting unit, the shape of which is complementary to the internal shape of the handle to allow its interlocking. Thanks to this mobile unit, sliding within the partially hollow handle is easy, without requiring moving parts external to the handle which could make the mower bulky and easily clogged and thus make cleaning complicated.
  • the mower comprises means for suspending the cutting unit.
  • an elastic means 8 is positioned in the handle, at the rear of the mobile unit in order to dampen the pressure of the motorized cutting unit on the skin.
  • This elastic means is preferably a spring, as shown in the figures, but can also be any other elastic means such as for example a piston.
  • the mobile unit will more or less press on the elastic means, performing back and forth movements when trimming the beard thanks to the telescopic interlocking of the mobile unit in the handle.
  • This elastic means therefore makes it possible to compensate for the movements of the user, which may be too abrupt, jerky or of too high a force.
  • the suspension system therefore makes it possible on the one hand to soften the movements of the user in order to make the sensation more pleasant, but also to obtain a more uniform cutting length. Indeed, when the user exerts too much pressure on the skin, the blades of the cutting head are closer to the skin and this results in a shorter cutting length. You should know that a beard trimmer is difficult to handle due to the different angles of the face and that keeping the same pressure throughout the shave is not easy for the user.
  • the figure 2 illustrates the mower with the mobile unit in the rest position.
  • the spring travel is maximum because the cutting head is not under any pressure.
  • the mobile unit is in a forward position (that is to say, it is fully extended from the handle).
  • the mower comprises at least one stop element 9 to block the mobile unit when the stroke of the elastic means is maximum (see Figure 6 ).
  • the latter is in the form of a stud provided on the mobile unit and coinciding with a complementary slot provided in the handle. In this way, the mobile unit is blocked by the stud located at the bottom of the slot when the travel of the spring is maximum, thereby preventing the mobile unit from coming completely out of the handle.
  • This stop element can be in any other form, as long as it makes it possible to retain the mobile unit inside the handle when the stroke of the spring is maximum, (for example in the form of an annular or semi- annular).
  • the Figure 3 illustrates the mower with the spring represented according to a minimum stroke, the latter being crushed by the mobile unit following the pressure exerted on the cutting head.
  • the Picture 7 shows an example of a compression stop 14 located on the mobile unit, the latter being shown in a visible manner.
  • the compression stop is in this case a semi-annular surface, located on the periphery of the mobile unit and which is in reality only partially visible when the cutting unit is in the rest position.
  • This compression stop can be in any other form. It allows the handle to be locked by compression, when the spring is compressed by the mobile unit when pressure is exerted on the cutting head. The handle therefore comes into contact with this compression stop, which in the case illustrated, coincides with the cylindrical shape located inside the handle or forming the handle.
  • the travel of the elastic means, and therefore the distance of movement of the mobile unit towards the inside of the handle is preferably between 10 and 30 mm, more preferably between 15 and 25 mm and is even more preferred 20 mm.
  • the object of the beard trimmer according to the invention is also to offer the user a device with a space-saving and light cutting unit which makes it possible to trim the smallest places on the face and which at the same time allows a great freedom of movement.
  • the inventor has considerably simplified the suspension system.
  • the motorized cutting unit and the elastic means are aligned, as shown in the Figure 4 .
  • the sliding axis of the mobile unit and the axis of displacement of the elastic means are parallel and preferably even identical (axis 12). This simplification of the means for suspending the cutting head makes it possible to limit the size around the cutting head and to have an ergonomic handle.
  • the cleaning of the cutting head is facilitated by the fact that the cutting unit is further from the handle when it is at rest because it is pushed by the elastic means. It can therefore be passed more easily under water without wetting the rest of the mower. However, it is preferable that the cutting head be removable, in order to be detached from the rest of the clipper to allow more efficient cleaning.
  • the mower also includes a protective cover 7, to protect the engine block and limit the deposit of hair on the mobile unit and therefore the engine block.
  • the mower may also include means for adjusting the damping force of the elastic means 8 (not shown).
  • This can, for example, be a wheel on the handle of the mower which can be operated by the user in order to modify the stroke of the elastic means to modify the damping force. This allows the user to choose the damping force that best suits the type of beard trimming they practice. Setting a low damping stroke will increase the force needed to dampen skin contact and setting a high damping stroke will make the trimmer much more sensitive to pressure.
  • the mower is equipped with a mechanism for locking the cutting unit in at least one fixed position. The user can thus block the cutting head at a certain distance from the handle if he wishes to temporarily no longer use the mower's suspension function.
  • the trimmer of the present invention may also include a rechargeable battery, as shown in the figures.
  • the trimmer can thus be used cordlessly.
  • the mower can also be provided to operate only on the mains with a power cable, or else be provided with a combination of the two power supply modes (on the mains or on the battery).
  • the motor is powered via an electric wire 11 connecting it to the electronic system and to the battery 10 of the mower.
  • the wire 11 is wound (for example inside the spring 8 as illustrated in the figure 2 and 4 ), in order to absorb the movements of the mobile unit 6.
