Definitions
- the invention relates to a heated cutting instrument with at least one shaft, each of which is heated by means of at least one heating element, the heating element being operatively connected to a regulating or control device for setting the temperature.
- Such a cutting instrument is already known from WO 92/00688. It is a heated pair of scissors, with two blades each with a cutting edge, each blade being provided on the side facing away from the cutting edge with a recess for receiving a heating wire, which extends almost parallel to the cutting edge over almost the entire length of the blade .
- the shear blades can be heated using the heating wire.
- the heating wire is operated in connection with a sensor-controlled control device.
- the heating wire in these scissors is installed in a recess that is freely accessible from the outside, appropriate covers are required in order to provide electrical insulation and / or protection against burns.
- the scissors in question are mainly used with special protective gloves.
- a cutting instrument with a blade is known from US Pat. No. 3,892,024, which has a cavity for receiving an electrical heating element.
- This blade can be made from two parts welded or glued together. In a preferred embodiment, the clinch executed in one piece. The cavity is created using bending technology and the blade is welded at its edges.
- both the two-piece and the one-piece blade have a welded or glued seam in the region of the severely stressed cutting edge. As a result, the cutting edge of such a blade can only be ground poorly.
- slim cutting edges which are desirable for scissors, for example, are virtually impossible.
- Another solution known from DE-U 295 06 308 therefore provides at least partial covering of the shear blades by means of a plastic body which can be fastened accordingly.
- a heating foil for heating the shear blades is arranged between the shear blades and the plastic bodies mentioned.
- moisture can easily penetrate into the space between the plastic body and the shaving blade, which sooner or later leads to malfunctions in the scissors.
- the object of the invention is therefore to create an improved heated cutting instrument, the heating element of which is effectively protected against any external influences.
- the heated shaft is formed in one piece and without holes and has a channel-like recess for the complete reception of a heating element, which is incorporated into the respective solid material of the shaft and directly in the area of a cutting edge or blade of the cutting instrument is arranged so that the heating element is completely accommodated within the shaft and the shaft is designed free of connecting seams in the region of the cutting edge or blade.
- the heating element of the cutting instrument is thus completely enclosed by the respective shaft.
- the encapsulated heating element is completely electrically insulated, so that the cutting instrument can be cleaned under running water. Any electrical short circuits or corrosion due to the effects of moisture are also excluded.
- the shaft of the cutting instrument has a completely flat surface, so that cleaning is also made easier in this respect. Any depressions that are a preferred bacterial focus after only a short use are not necessary, at least for heating the shaft.
- an improved heat transfer and thus a higher energy efficiency is achieved.
- the incorporation of the channel-like recess into the solid material prevents any adhesive or weld seams from being arranged in the region of the cutting edge. Rather, no seam connection is required at all.
- the recess in the shaft suitable for holding a heating element is advantageously precisely manufactured by means of an electron erosion process.
- the scissors according to the invention can also be used while maintaining the advantages mentioned.
- This groove is then closed again with a closure part, leaving the channel-like recess for receiving the heating element, and the closure part is joined to the rest of the shaft part by means of a suitable connection technique, preferably welding, in such a way that the unity of the shaft is again ensured.
- This shaft piece is then processed in such a way that the shaft has a blade or a cutting blade.
- This type of production also makes it possible to prepare a one-piece shaft for receiving a heating element without the need for bores or the need for connection seams in the later cutting blade or blade area.
- the heating element in the shaft is preferably arranged parallel to the preferred direction of the cutting edge results in an approximately uniform heat distribution over the entire length of the cutting edge. This is important, for example, in connection with the cautery of hair when cutting hair.
- the heated shaft is provided with a plastic cover.
- the plastic cover is detachably fastened in each case. As a result, any plastic covers can be easily removed for basic cleaning of the cutting instrument and can be completely replaced from time to time for hygienic reasons.
- a clip solution according to claim 5 enables a particularly simple cleaning of the cutting instrument. At least the shaft of the cutting instrument is cut from the full material. This eliminates the usual forging process and thus the risk of embrittlement of the shaft material.
- At least the shaft of the cutting instrument is made of nickel-free material.
- a further embodiment of the heated cutting instrument provides a temperature sensor inside the shaft in order to be able to carry out a real comparison of the actual setpoint. This results in a self-controlled temperature control for the cutting instrument.
- Heated scissors are particularly suitable as the cutting instrument according to the invention, with the entire half part of the scissors being cut from the solid in an advantageous embodiment.
- the heated scissors are equipped with a ball bearing at the crossing point.
- Scissors of this type have proven to be particularly durable, robust and, above all, to run smoothly over the long term.
- the scissors have the necessary "bite”.
- the ball bearing as such can advantageously be accommodated below the head of a screw of a screw-nut connection of the scissors.
- the handles of the heated scissors are advantageously housed in plastic half-shells.
- the user is effectively protected against burns on the metal handle pieces that may heat up.
- the power supply line of the respective heating element can be guided in a protected manner within the plastic half-shells.
- Fig. 1 is a pair of scissors in a plan view
- Fig. 2 is a cross-section not to scale along the section line II-II in Fig. 1 and
- Fig. 3 is a scissor blade of the scissors shown in Fig. 1, not shown to scale.
- Fig. 4 is a half part of a pair of scissors in a plan view
- Fig. 5 is an exploded view of a screw-nut connection in the hinge part of the scissors.
- the heated cutting instrument shown in FIG. 1 is a pair of scissors 1, as is usually used by hairdressers.
- the scissors 1 comprises two heated shear blades 8, each of which merges into a handle 3 on the side of the scissors 1 facing away from the cutting side.
- the handle 3 consists essentially of a retaining eye 4 with a plastic jacket 5.
- the retaining eyes 4 can be arranged at the same height or offset from one another. Often, a finger rest for the fingers not accommodated in the eyelet 4 is additionally molded onto one of the holding eyes 4.
- the shear blades 8 are connected by a joint part 6, the pivot point of which is marked by a screw 7.
- the screw 7 connects the two shear blades 8. By means of the screw 7, an additional spherical joint fixation.
- the edge of each shear blade 8 facing the other shear blade 8 is designed as a cutting edge 10.
- a recess 11 is provided in the shaft 2 of the shear blade 8.
- the cutout 11 is arranged at least approximately parallel to the cutting edge 10 in the region of the cutting edge 10 in accordance with the line shown in dashed lines in FIG. 1.
- a heating resistor 12 is received in the recess 11 and is connected to a power supply line 13.
- the power supply line 13 has a branch 14 in the region of the joint part 6.
- the heating resistors 12 can be connected in series or in parallel.
- the branching 14 enables the heating resistors 12 to be supplied via a single power supply line 13, which is connected via the handle 3 with an external cable 15 to a current regulator.
- the cable is detachably attached to the handle 3 via a plug connection 17.
- the shear blades 8 are heated via the heating resistors 12.
- the shear blades 8 can be provided on the outside with a plastic cover.
- the shear blades 8 according to FIG. 3 have recesses 16 for fastening a corresponding plastic cover.
- the plastic cover has a shape which essentially corresponds to the corresponding shear blade 8.
- the plastic covers have retaining lugs that releasably lock within the recesses 16. When the plastic cover is attached, burns on the heated shear blades 8 are virtually impossible. The manufacture and function of the heated scissors 1 is explained below:
- the shear blades 8 with their shank 2 form a half part 18 with the handle 3 and the joint part 6.
- the scissors 1 essentially consist of two half parts 18 connected by means of the screw 7 milled to the full. Such a half part 18 is shown in FIG. 4.
- the half part 18 has a shoulder 20 in the area of the transition from the shear blade 8 to the joint part 6.
- the shoulder 20 covers the front side of the scissor blade 8 facing the handle 3.
- the half part 18 is now clamped and exposed to an electron beam on the part of the shoulder 20.
- the recess 11 is cut into the shear blade 8 from the shoulder 20 in an electron erosion process.
- the precision of the electron erosion process makes it possible to drive the recess 11 to a desired depth and to precisely provide the arrangement of the recess 11 shown in dashed lines in FIG. 1.
- other arrangements can also be implemented analogously.
- the heated scissors 1 described above do not necessarily have to be produced by means of an electron erosion process. It has proven to be an economically practicable and even technically superior solution to mill the channel-like recess 11 for receiving the heating element 12 in the shaft 2 into the shaft 2 from the side facing away from the cutting edge 8.
- the shaft 2 is then closed again with a closure piece with a recess in the recess 11, preferably by means of a weld seam outside the cutting blade area. sen.
- the then one-piece shaft piece is then primarily machined to produce the desired cutting blade.
- a heating element 12 is then introduced into the recess 11, each of which is connected to a power supply line 13 which is led out of the opened shoulder 20.
- This power supply line 13 is now received in the plastic sheath 5 of the handle 3 formed by half-shells and connected to a plug connection 17.
- the scissors 1 is then fully assembled.
- the scissors 1 can then be connected via the connector 17 and a cable 15 to a current regulator, not shown.
- the temperature is then set by regulating the current.
- a temperature sensor is fastened in the recess 11 or elsewhere.
- the temperature sensor detects the actual temperature value of the heated shaving blade 8. This actual value is transmitted to the current regulator supplying the heating resistors 12.
- the current regulator, the heating resistor 12 and the temperature sensor (not shown) thus form a closed temperature control circuit for the heated scissors 1.
- the scissors 1 can be used with an adjustable, almost constant operating temperature.
- the usual operating temperature of a pair of scissors 1 heated in this way is between 100 ° and 300 ° C. for hairdressing applications.
- the two half parts 18 are connected to one another in the region of the joint part 6 by a screw-nut connection. At this point, a ball bearing 24 according to FIG. 5 is arranged.
- the two half parts 18 are connected to one another in the region of the joint part 6 by the screw 7.
- the screw 7 is provided with a chamfer 21. As a result, it is rotatably connected to one of the two half parts 18.
- the two half parts 18 are screwed together by means of a knurled nut 22.
- the “bite” of the scissors 1 can be adjusted by the knurled nut 22.
- the knurled nut 22 is connected with the screw 7 with the interposition of a Teflon disk 23 and the ball bearing 24.
- the ball bearing 24 sits under the screw head on one half part 18 and the Teflon disk 23 on the other half part 18 in contact with the knurled nut 22.
- the heated scissors 1 is used in the hairdressing area for hair cutting.
- the hair cut using scissors heated in this way melts at the cut edge due to the elevated temperature.
- the tips of the hair are cauterized. This means that the ends of the hair are sealed and the stress on the hair is reduced.
- the clumping of the hair tips sometimes observed in connection with the cautery of the hair can be avoided by means of the exact temperature which is possible here and is constant over the entire length of the shaving blade 2.
- the hair ingredients are retained due to this gentle cutting method.
- the hair cut in this way looks healthier and stays shiny longer. In addition, this is what is feared in hairdressing circles Counteracted split ends.
- the cutting of the hair tips which is otherwise necessary at regular intervals, can be dispensed with entirely or at least is only required at longer intervals.
- the scissors 1 which is extremely easy to move due to the ball bearing, can be easily cleaned under running water, since all electrical installations are fully integrated in the blade 8.
- the plastic covers are only clipped onto the recesses 16 and can be easily detached for cleaning purposes and replaced from time to time for hygienic reasons.
- the heating resistors 12 are arranged in the shaft 2, the entire heat emitted by the heating resistor 12 is absorbed by the shear blade 8, passed on and radiated in the area of the cutting edge 10.
- the cutting edge 10 has the desired target temperature almost over its entire length. Any heat loss is only given off indirectly via the shaft 2 or the shaving blade 8 itself and is thus significantly reduced compared to direct heat radiation from an exposed heating element.
- the scissors 1 according to the invention can thus be heated with high energy efficiency.
- a heated pair of scissors 1 enumerated above for the exemplary embodiment can also be readily used in conjunction with heated blades, knives, combs or other cutting instruments.
- a cutout 11 in the respective shaft 2 for receiving a can be made in the region of a cutting edge 10 of a comb by means of the described electron erosion method Heating resistor 12 are provided to achieve the advantages of a uniform temperature distribution with high energy efficiency.
- the manufacture and function can be carried out analogously to the scissors 1 described above.
