Definitions

  • the invention relates to a hair clipper with a lower blade and a top blade, which are adapted to move in a switched-on operating state of the hair clipper relative to each other, wherein between the lower blade and the upper blade friction surfaces are provided.
  • the term "lower blade” is meant that of the two knives, which is arranged at a free longitudinal end of the hair clipper, so that it can get into direct, sliding contact with the scalp during hair cutting, whereas the term “upper blade” that of two knife is meant which is arranged on the opposite side of the scalp relative to the scalp.
  • Such hair clippers are found in hairdressing salons, but also in private households numerous. In most cases, these are wireless devices, which have a rechargeable battery or a receptacle for, if desired, rechargeable batteries.
  • the lower blade is substantially rigidly connected to the main body of the hair clipper, whereas the upper blade can be displaced by reciprocating relative movement to the lower blade by means of a motor and, for example, an eccentric assembly. Both the lower blade and the upper blade are provided at their front end with a plurality of protrusions with ground flanks. Introduced between these projections hairs are sheared in the on state of the hair clipper by the reciprocal relative movement.
  • the two blades of the hair clipper must, at least in the region of their projections, abut each other to achieve the desired shear effect.
  • the upper blade is also pressed with suitable spring means elastically against the lower blade in order to achieve the desired shear effect even at low abrasion or closure on the lower and / or upper blade.
  • the friction occurring between the two blades during operation of the hair clipper is disadvantageous, at least if it exceeds a certain level, since on the one hand the motor has to do more work and thus the energy consumption is increased, and on the other hand an increased wear the friction surfaces between the two knives is created, which can lead to a complete inability of the hair clipper.
  • the two blades of the hair clipper especially in the region of their friction surfaces, provided with lubricating oil when they leave the factory to get into the trade.
  • the problem is, however, that the lubricating oil does not remain indefinitely between the two blades of the hair clipper, but that it is "consumed” over time. For example. It is easily wiped off the hair clipper when cleaning the hair clipper together with cut hair residue.
  • the US 2,194,465 A describes a hair clipper with a lower blade and a top blade and with a kind of distribution element for receiving lubricating oil and delivery of the lubricating oil to the knife, wherein the distribution element is disposed in an opening in the lower blade.
  • the GB 398 137 A describes a lubricating device for a sewing machine.
  • the patent GB 854 667 A describes a hair clipper with an upper blade and a lower blade, wherein the upper blade is mounted on a guide rod, and on the guide rod, a lubricant-impregnated felt for lubricating the guide rod is provided.
  • a hair clipper of the type mentioned above which comprises a distribution element which is adapted to receive and store externally supplied lubricating oil and which is also suitable, in the activated operating state of the hair clipper, the stored lubricating oil to the lower blade and the upper blade , at least partially, to dispense again to lubricate the friction surface between the lower blade and the upper blade.
  • a lubricating oil reservoir is thus provided directly on the hair clipper, which automatically ensures, during operation of the hair clipper, that the friction surfaces between the upper blade and the lower blade are adjusted in order to replace lubricating oil, which previously, eg. when cleaning after the last use of the hair clipper, lost.
  • a sufficient lubrication of the friction surfaces between the two blades of the hair clipper is always ensured so that over time increased power consumption and / or wear on the hair clipper can be prevented or at least significantly reduced.
  • the distribution element between the lower blade and the upper blade can be arranged.
  • the paths for the lubricating oil are relatively short to lead to the corresponding friction surfaces.
  • the upper blade does not have to rest against the lower blade over its entire side facing the lower blade, a corresponding free space can be provided between the upper blade and the lower blade, which can be used for receiving the distributor element. It is particularly advantageous if the distribution element is fixed to the upper blade.
  • the lower blade is usually arranged rigidly on the main body of the hair clipper, whereas the upper blade by a motor and, for example, a Exenterantrieb to a reciprocating motion relative to the lower blade is driven.
  • the distributing element is fixed to the upper blade, relatively high acceleration forces act on the distributing element due to the reciprocal movement, with the result that lubricating oil stored in the distributing element is at least partially released from the distributing element. Since the upper blade moves back and forth relative to the lower blade by the reciprocal movement in the transverse direction of the hair clipper, in this way the lube oil released is well distributed between the two blades and can sufficiently wet the friction surfaces between the two blades.
  • This configuration can therefore ensure a structurally very simple manner that during operation of the hair clipper, the lubricating oil is automatically discharged to the friction surfaces between the two blades.
  • the distribution element is preferably in direct contact with both the upper blade and the lower blade of the hair clipper.
  • the delivery of lubricating oil stored in the distribution element to the upper blade and the lower blade is also promoted by the capillary effect.
  • the distribution element is essentially formed from a material which is suitable for sucking in and storing lubricating oil, at least temporarily.
  • a material may, for example, be a felt or an open-pore foam. This can, when it comes into contact with externally supplied lubricating oil, suck it up, similar to a sponge, to give it later, for example, by the reciprocal movements in the activated state of the hair clipper, over a period of time again.
  • an access is provided in the lower blade, through which the distribution element is accessible from the outside to supply, preferably in a switched-off operating state of the hair clipper, the distribution element with fresh lubricating oil.
  • the access can be provided in the form of an opening, for example.
  • a bore which is dimensioned sufficiently large to direct contact of a transport element for transporting lubricating oil from outside the hair clipper, such as eg a wick to allow with the distribution element.
  • This could be, for example, a cylindrical bore, which may have a diameter of several millimeters to more than one centimeter, but preferably not more than 4 centimeters.
  • the insert in the opening, which prevents hairpieces or other contaminants can pass through the opening to the distribution element, wherein the insert consists essentially of a porous material, such as a sintered material is formed, which allows by capillary action a passage of lubricating oil from outside the hair clipper to the distribution element, wherein the insert preferably substantially completely fills the opening.
  • a holder may be used for the above-described hair clipper, the holder preferably including an electrical interface for connecting a rechargeable battery in the hair clipper to an external power network when the hair clipper is in the holder, the holder comprising a feeding device for feeding lubricating oil to the hair clipper, the feeding device in turn having a fixing portion for releasably attaching a lubricating oil reservoir to the feeding device, for example by means of a screw thread, and a transporting element for transporting lubricating oil from the lubricating oil reservoir to the hair cutting machine Hair clipper, in particular to the distribution element of the hair clipper comprises.
  • hair clippers known in the art are already supplied as standard with a bracket. If the hair clipper includes a rechargeable battery, it is usually automatically recharged when the hair clipper is not in use but instead is in the holder. Such a holder is therefore often referred to as a "charging stand”. It should be noted, however, that the described holder is by no means limited to loading stands for hair clippers comprising a rechargeable accumulator. It can also hair clippers, which are powered by a power cord in operation with electric power supplied by means of the bracket lubricating oil.
  • the distribution element of the hair clipper when the hair clipper is in the holder again, substantially completely, to fill with lubricating oil, which then can deliver it in the operating state of the hair clipper to the friction surfaces between the lower blade and the upper blade.
  • the user has only occasionally refill a lubricating oil reservoir with lubricating oil, or replace it with a full lubricating oil reservoir, wherein the lubricating oil reservoir can be releasably secured by means of the mounting portion to the feeder of the holder.
  • the lubricating oil storage container is preferably dimensioned such that it is able to absorb significantly more lubricating oil than the distribution element provided on the hair cutting machine. Depending on the frequency and duration of use of the hair clipper, it may thus be sufficient to fill the lubricating oil reservoir only once a year, or even less frequently, or to replace it with a full lubricating oil reservoir.
  • the lubricating oil reservoir is made of a transparent material, or at least a transparent Section, the user of the hair clipper can always easily check the current level in the lubricating oil reservoir.
  • the lubricating oil reservoir can be made of glass, but preferably of a transparent plastic.
  • the transport element which will be discussed in more detail below, serves to transport the lubricating oil from the lubricating oil reservoir to the hair clipper.
  • the supply device of the holder further comprises spring means for resiliently supporting the transport element relative to the rest of the feeding device, so that a portion of the transport element is pressed against a portion of the hair clipper when the hair clipper is in the holder.
  • the spring means may be, for example, conventional coil springs or the like.
  • the delivery device may comprise a coupling portion for, preferably releasably, coupling the delivery device to the rest of the support.
  • the holder optionally, at least if it is provided with an electrical connection to use exclusively as an electric charging stand, or alternatively also for filling the distribution element on the hair clipper. It is also conceivable to retrofit existing loading stands by simple coupling quickly with a feeder.
  • the transport element is preferably designed such that it is able to guide lubricating oil to the hair clipper due to capillary forces from the lubricating oil reservoir - even against gravity.
  • the transport member can extend into the same through an opening of the lubricating oil reservoir, wherein the opening of the lubricating oil reservoir is arranged above the lubricating oil level so that no lubricating oil can leak from the lubricating oil reservoir.
  • the transport element can be formed, for example, from a suitable cotton wick or from a suitable fibrous material or from a capillary tube with a suitable inner diameter or from sintered porous materials, for example a sintered metal.
  • a cotton wick may be similar, as is known, for example, in oil lamps.
  • the hair clipping machine according to the invention may be part of a set, which further comprises: the above-described holder for this hair clipper and a lubricating oil reservoir.
  • These elements can be distributed together as a set, the items can interact in such a way that the user of the hair clipper over a very long period of time, for example, for more than a year, does not care about the supply of the hair clipper with lubricating oil without It would therefore come - even with regular use - to a lack of lubrication of the friction surfaces between the lower blade and the upper blade of the hair clipper.
  • the transport element of the holder, the distribution of the hair clipper and the other parts are preferably coordinated so that there is no time to excessive oiling of the two blades of the hair clipper.
  • Parameters which have an effect on the extent of oiling are, in particular, the absorbency and density of the distribution element used and the transport element used. If an insert is provided in the lower blade, the porosity of the insert may also play a role. If the transport element is essentially formed from capillary tubes, the number and diameter of the capillary tubes can also have an influence on the extent of the oiling. The same applies mutatis mutandis to the holes if the lower blade instead of an insert has holes.
  • the lubricating oil reservoir comprises an opening and an outer threaded portion or a bayonet catch portion or clip connecting portion surrounding the opening, the mounting portion of the retainer of the retainer having a complementarily formed inner portion or bayonet catch mating portion or clip mating counter portion which is suitable. engage with the male threaded portion and the bayonet fitting portion and the clip connecting portion of the lubricating oil reservoir, respectively.
  • the lubricating oil reservoir can be easily connected to the feeder, for example, on or unscrewed, such as when refilled with fresh lubricating oil or replaced by another full lubricating oil reservoir shall be.
  • the lubricating oil reservoir may be, for example, a vial having an externally threaded portion.
  • the holder is provided with a latching mechanism which acts between the mounting portion and the rest of the holder.
  • the lubricating oil reservoir may include a closure cap for closing its opening when the lubricating oil reservoir is not attached to the attachment portion of the feeder of the holder.
  • the closure cap preferably comprises an internally threaded section or a bayonet closure counterpart section or a clip connection counterpart section which is suitable for engaging the externally threaded section or the bayonet connection section or the clip connection section of the lubricating oil reservoir.
  • the same male threaded portion or bayonet coupling portion of the lubricating oil reservoir can be used both for the attachment portion of the feeder of the holder, as well as for the cap. Since, when the lubricating oil reservoir is attached to the mounting portion of the feeding device of the holder, the cap is not needed, and there is a risk that it will be lost, it is proposed that the holder further comprises a receptacle for receiving the cap when the lubricating oil reservoir is fixed to the attachment portion of the feeding device of the holder. Thus, the cap can be stored in a safe place in the immediate vicinity of the used lubricating oil reservoir, which reduces the risk that the cap is lost.
