Definitions
- Heated cutting instrument in particular scissors, knives, hair clippers or the like
- the invention relates to a heatable cutting instrument, in particular scissors, knives, hair clippers or the like, with a cutting blade with an electrical heating element for heating and with an electrical connection for operating the electrical heating element by means of an electrical voltage supply device
- Heated cutting instruments in particular heated scissors for cutting hair, have the advantage that the hair tips are cauterized by the hot cutting blades during the cutting of the hair. This means that the hair tips melt easily. The hair tips are thus sealed to a certain extent and counteracted by hair splitting
- a heated cutting instrument in the form of a heated pair of scissors of the type specified at the outset is known from WO 92/00688.
- the basic idea then is to arrange a separate metal cutting element with a front cutting edge on a blade holder defining a basic body.
- the blade holder has a recess , into which the cutting element is inserted and screwed to the blade holder
- a separate heating foil is arranged between the blade holder and the cutting element. This is supplied with electricity by an electrical voltage supply device.
- the heating resistor heats up the cutting element.
- the disadvantage of this known heated scissors is that Arrangement of the heating element in the form of a separate heating foil, which must be arranged between the blade holder and the actual cutting element.
- a disadvantage is that moisture can very easily penetrate, which can lead to destruction of the heating foil. Also i the assembly of the heated scissors is cumbersome
- the scissors can be any type of scissors, for example hairdressing scissors, tailor scissors, household scissors, poultry scissors, paper scissors, hedge trimmers etc.
- Such scissors basically have two cutting blades, each of which has an operating handle at the rear end Have a finger eyelet.
- the cutting blades can be pivoted relative to one another about an axis of rotation.
- This swivel device is formed by a screw which serves as an axis of rotation.
- the problem with such scissors is that the pivoting device has a relatively large frictional resistance, so that the scissors are stiff. This is particularly disadvantageous wherever scissors have to be used to cut finely and precisely, such as hairdressers, since smooth scissors are required there.
- the invention is based on the objective of creating a heatable cutting instrument with an improved design of the electric heating element and with improved handling.
- the invention proposes that the electric heating element be permanently and firmly attached to the cutting blade.
- the advantage of the heatable cutting instrument designed in this way is that the electrical heating element is integrated into the cutting blade due to its non-detachable, permanent and fixed arrangement, and overall a compact cutting blade / heating element unit is formed. Due to the fixed attachment of the heating element to the cutting blade, the heating element is encapsulated to a certain extent and is therefore less accessible to moisture and thus corrosion compared to known heating foil arrangements.
- the great advantage of the heatable cutting instrument according to the invention lies in its very high functional reliability with a long service life without failures.
- the electrical heating resistor is supplied with voltage via a corresponding electrical control unit. So that the cutting blade has the desired temperature, there is preferably a temperature sensor in the heating area for an exact temperature measurement. Solution provided Just like the heater, the temperature sensor can also be fixed to the cutting blade. Alternatively, it is also conceivable that it lies separately on the cutting blade. This temperature sensor is also connected to the control unit
- the electric heating element is printed, sintered on or glued onto the cutting blade. Further mounting options are conceivable. Printing in particular represents the preferred arrangement of the electric heating element on the cutting blade. In this case, no heating foil is used. Rather, the heating element is used Applied to the cutting blade by means of thick-film technology In particular, the electric heating element is printed on using screen printing.This means that an electrically conductive paste is printed on, that is, applied and then burned in bring to
- the electrical heating element is in the form of a stick along the cutting edge of the cutting blade.
- the heating element is thus designed as a thin line which extends along the cutting edge at a parallel distance therefrom
- the cutting blade is preferably made of metal or ceramic.
- a cutting blade made of ceramic is distinguished by a long service life with regard to its sharpness properties
- the cutting blade is under electrical voltage.
- the cutting blade consists of an electrically conductive material, namely metal.
- the cutting blade is arranged as a separate component on a base body. This has the advantage that the heating element can be attached to the cutting blade in a simple manner.
- the cutting blade prepared in this way can then be used on the actual base body of the cutting instrument, for example glued, riveted or screwed on preferably the base body will have a corresponding recess into which the cutting blade can be inserted
- the basic body can consist of plastic or ceramic. Plastic is the preferred material since a basic plastic body can be produced by a simple injection molding process
- the basic body is made of metal.
- conventional metal scissors can be used.It is only necessary to make a corresponding recess in the basic blade area in order to insert the cutting blade, in which case the separate cutting blade with integrated heating is then inserted and can be attached
- An insulation is preferably arranged between the base body and the cutting blade. This insulation serves as thermal insulation and as electrical insulation of the hot and live cutting blade from the metal base body.This ensures that the actual base body of the cutting instrument does not heat up and thus the risk of burns is avoided
- the basic body has a actuating grip, thermal insulation being provided in the area between the basic body with the heated cutting blade and the actuating handle. This can be achieved with the metal scissors by removing the metal in this area and is replaced by plastic. As a result, heat conduction to the actuating device is largely prevented, so that additional protective mechanisms in the area of the actuating device can be dispensed with
- a further preferred development proposes that an electrical plug connection for a connecting cable of the electrical voltage supply device of the electrical power supply of the heating elements is arranged on the cutting instrument.
- the basic idea is then not to lead the connecting cable of the electrical voltage supply device directly to the heating element, but rather the connection through an electrical plug connection
- the electrical plug-in connection can be made by plug / socket.
- the electrical plug-in connection is thus firmly integrated in the cutting instrument. The advantage is that if the connecting cable breaks, it is quick and easy can be replaced without having to disassemble the entire scissors including the heating element, for example.
- the electrical plug connection is preferably arranged in the actuating handle. This represents a technically simple possibility to be able to connect the connection cable to the electrical plug connection. In the case of heated scissors, the electrical plug connection will have to be arranged in particular in the region of the one finger eyelet.
- the cables run from the electrical plug connection to the electrical heating element within the body of the cutting instrument. This has the advantage that the cables do not interfere. With scissors, the cable guide will be in the grip area.
- the cutting instrument is a pair of scissors with two cutting blades which can be pivoted relative to one another about an axis of rotation by means of a pivoting device having a roller bearing.
- the advantage of such a pair of scissors using a roller bearing is that the pair of scissors is considerably smoother than conventional scissors, since the roller bearing reduces the frictional resistance.
- roller bearing is to be understood as a generic term, which includes all bearings which are intended to reduce the frictional resistance between two moving parts.
- the roller bearings include ball bearings, plain bearings and needle bearings.
- the roller bearing has an outer ring and a concentric, rotatable inner ring, the outer ring being rotatably connected to one cutting blade and the inner ring to the other cutting blade.
- the two roller bearing rings are coupled in terms of movement to the two cutting blades. This can be done directly by the corresponding roller bearing ring resting directly on the associated cutting blade.
- an indirect connection is also conceivable, for example by arranging intermediate elements between the roller bearing ring and the associated cutting blade.
- the swivel device has a screw that passes through an aligned opening between the two cutting blades Mother. This represents the conventional technical implementation of a swivel device for scissors.
- roller bearing is arranged on the outside of the one cutting blade, the outer ring being connected in a rotationally fixed manner to this outside of the cutting blade and the inner ring being connected in a rotationally fixed manner to the screw or the nut.
- the basic idea of this roller bearing arrangement is therefore that the roller bearing is not arranged between the two cutting blades, but that the roller bearing is assigned to one cutting blade.
- the connection of the rolling bearing to the other cutting blade is realized by the screw passing through, which is indirectly connected to the other cutting blade.
- roller bearing is inserted into an outside recess of the one cutting blade in a press fit.
- This press fit the non-rotatable connection of the outer ring of the rolling bearing to the one cutting blade is realized.
- This press fit is sufficient to hold the rolling bearing securely since the pivoting force is relatively low with scissors.
- the head covers the recess.
- the head preferably covers the recess in a sealing manner. This protects the rolling bearing from contamination and keeps it running smoothly.
- a ring of balls or camming cylinders is arranged concentrically around the axis of rotation between the two cutting blades. This means that the mutually facing surfaces of the cutting blades slide directly on these balls or rolling cylinders.
- FIG. 1 is a view of a first embodiment of the scissors
- FIG. 2 shows a section through the cutting blade of the scissors in FIG. 1,
- FIG. 4 shows a single view of the cutting blade of the scissors in FIG. 1,
- FIG. 5 shows a detailed section of the scissors in FIG. 1 in the region of the plaster
- FIG. 6 is a view of a second embodiment of the scissors
- FIG. 7 shows a section through the scissors in FIG. 6 in the region of FIG
- FIG. 8 is an exploded view of the swivel device in FIG. 7
- the heatable scissors in FIG. 1 consist of a basic body 1 made of plastic.
- This basic body 1 has an actuating handle 2 with two finger sockets 3
- the base body 1 in the blade area has a separate cutting blade 4 made of ceramic.
- the cutting blade 4 has the usual cutting edge 5.
- the separate cutting blade 4 made of ceramic is inserted into a corresponding recess 6 in the base body 1 made of plastic and is firmly attached to it connected, for example glued, screwed or riveted
- this heating element 7 is a line and is printed on the cutting blade 4, for example by means of screen printing. In FIG. 2, the thickness of the heating element 7 is exaggerated. In reality, the thickness of the heating element 7 is only 4 micrometers.
- thermosensor (not shown) is also provided, which can equally be attached to the top of the cutting blade 4
- FIG. 3 A modified embodiment is shown in Fig. 3
- the base body 1 is made of metal and has a corresponding recess 6. This can be achieved, for example, by conventional metal scissors being milled out.
- an insulation 8 is additionally arranged between the cutting blade 4 and the basic body 1. This insulation 8 serves on the one hand as thermal insulation (so that the high temperature of the cutting blade 4 does not affect the Grundkorper 1 transferred) as well as electrical insulation
- Cables 9 are used for the electrical voltage supply of the heating element 7 (and of the temperature sensor). These are connected to the heating element 7, as can be seen in particular in FIG. 4.
- the cables are guided through the base body 1 to the rear to the actuating device 2 and end there in an electrical manner Plug connection 10, which is designed as an electrical socket.
- Plug connection 10 is designed as an electrical socket.
- an electrical connection cable can then be led from the electrical supply unit to the scissors and electrically connected to the electrical plug connection 10
- actuating handle 2 is formed separately from the actual basic body 1 and is fastened by means of a screw 11. As a result, different actuating handles 2 can be used according to the respective requirements. It can also be seen that between the actual basic body 1 and the actuating handle 2, a stopper 6 is arranged in the form of an O-ring. It can also be seen in this drawing how the cables 9 are guided through the actuating device 2 and open on the electrical plug connection 10 in the form of a plug socket
- the basic body 1 can also consist of metal.
- the metal substance in the area between the actual basic body 1 and the actuating element 2 must be removed down to a narrow web and replaced by an insulating element. This insulation is prevented an excessive heat transfer from the basic body 1 to the actuation device 2
- FIG. 5 it can also be seen in FIG. 5 that the interior of the finger socket 3 of the actuating device 2 is equipped with an exchangeable ring 13
- the scissors of the second embodiment in FIGS. 6 to 8 (in which the heating device is omitted for the sake of simplicity and clarity) conventionally has two cutting blades 21, 21 *.
- the cutting blades each have an actuating handle 22, 22 ' with finger sockets 23, 23 'in the intermediate area between the cutting blades 21, 21' and the actuating handles 22, 22 'there is a swiveling device 24 by means of which the two cutting blades 21, 21' can be swiveled relative to one another with respect to an axis of rotation A.
- the swiveling device 24 is through an opening 25 is formed in the two cutting blades 21, 2V, through which a screw 26 is inserted.
- This screw 26 has a head 27, which is bevelled on the underside in the outer region upwards on the opposite side of the head 27 of the screw 26 there is a nut 28
- This also has a head 29 and is t held positively in the lower cutting blade 21 '
- the swivel device 24 is additionally assigned a roller bearing 30 which is press-fitted into a recess 31 in the outside of the cutting blade 21.
- the roller bearing 30 has an outer ring 33 and an inner ring 34. Balls 35 are located between the outer ring 33 and the inner ring 34 In the middle, the roller bearing 30 has an opening 36 for the screw 26
- the outer ring 21 is non-rotatably arranged in the recess 21 of the cutting blade 21 by means of the press fit.
- the inner ring 34 can be freely rotated within the recess 31 the outer region of the underside of the head 27 of the screw 26 is bevelled upwards, it does not touch the upper side of the outer ring 33 of the roller bearing 30 If, for example, the lower cutting blade 21 'is rotated about the axis of rotation A with respect to the fixed upper cutting blade 21, the rotary movement is transmitted to the inner ring 34 of the roller bearing 30 via the nut 28, the screw 26 and its head 27. As a result, the cutting blade 21 'is very easy to move with respect to the cutting blade 21. By tightening the screw 26, the contact pressure between the two cutting blades 21, 21' can be changed.
