The blade edges (1) are formed to oppose each other in a tubular assembly (2) which is held on a forked handle (4) which vibrates longitudinally and allows the tube to pivot (5) to maintain contact with the facial skin.

Description

Stand der Technik:State of the art:

Ultraschall-Nassrasierapparate mit hochfrequent vibrierenden Klingen sind bereits nach DE 90 05 626 U1, DE-OS 21 60 474, DE-OS 15 53 680, US 25 30 759, US 24 85 056, US 33 62 068, DT 2355791, DE 4026142 A1, Europa 0266080 A1, Europa 025930481 B1, G 68909835.8, G 9005626 und DE 196 21 215 A1 bekannt. DE-C-448845 veröffentlicht einen Nassrasierapparat gemäß dem Oberbegriff des Patentanspruchs.Ultrasonic wet shavers with high-frequency vibrating Blades are already in accordance with DE 90 05 626 U1, DE-OS 21 60 474, DE-OS 15 53 680, US 25 30 759, US 24 85 056, US 33 62 068, DT 2355791, DE 4026142 A1, Europe 0266080 A1, Europe 025930481 B1, G 68909835.8, G 9005626 and DE 196 21 215 A1 known. DE-C-448845 publishes a wet shaver according to the preamble of the claim.

Trotz der vielen Ansätze wurden bisher diese Ultraschall-Rasierapparate vom Verbraucher nicht akzeptiert, weil der Schutzrahmen des Klingenblocks gemeinsam mit seinen fest mit ihm verbundenen Klingen vibrierte, wodurch die Gesichtshaut mit ihren Bartstoppeln ebenfalls in gleichsinnige. Vibration versetzt wird und somit die Schnittleistung unbefriedigend bleibt.Despite the many approaches, these ultrasound shavers have so far been used not accepted by the consumer because of Blade block protective frame along with its fixed blades associated with it vibrated, causing the Facial skin with her stubble also in the same direction. Vibration is offset and thus the cutting performance remains unsatisfactory.

Zudem erzeugt das Kribbeln der bisher mitvibrierenden Gesichtshaut beim Rasierenden aus Angst vor Verletzung eine instinktive Vorsicht und er drückt daher den Klingenblock zu schwach auf die Gesichtshaut, wodurch das angestrebt tiefe Abtrennen der Bartstoppeln unmittelbar an der Hautoberfläche ausbleibt.In addition, the tingling creates the vibrating so far Facial skin when shaving for fear of injury instinctive caution and he therefore closes the blade block weak on the facial skin, which is aimed at the deep Cut off the stubble immediately on the surface of the skin absent.

Bei mit Batterie betriebenen Ultraschall-Nassrasierapparaten ist die auf den Klingenblock zu übertragene Vibrationsleistung ohnehin begrenzt, sodaß es außerdem von Vorteil ist, wenn möglichst wenig Masse, also nur die Klingen und nicht der sie umgebende Schutzrahmen mit seiner Haut-Vorspannleiste und damit auch nicht die berührte Gesichtshaut mitvibriert. In the case of battery-operated ultrasonic wet shavers the vibration power to be transmitted to the blade block limited anyway, so it's also an advantage if as little mass as possible, so only the blades and not the blades surrounding protective frame with its skin biasing strip and so that the touched facial skin does not vibrate.

Der Erfindung liegt die Aufgabe zugrunde, die oben erwähnten Nachteile zu verringern.The invention has for its object the above mentioned Reduce disadvantages.

Diese Aufgabe wird durch einen Nassrasierapparat gemäß Anspruch 1 gelöst.This task is accomplished by a wet shaver Claim 1 solved.

Wenn die Klingen nahezu unbehindert vom Gleitschuh vibrieren, dann vibrieren weder der Gleitschuh noch die Gesichtshaut mit, die Bartstoppeln bleiben somit in Ruhe und werden besser von den gegen sie vibrierenden Schneidkanten der Klingen abgetrennt. Die Entkopplung ist so gelöst, daß bei Vibration der Klingen kein Prellgeräusch entsteht.When the blades are almost unhindered by the shoe vibrate, then neither the shoe nor the vibrate Facial skin with, so the stubble stays calm and become better from the cutting edges vibrating against them the blades severed. The decoupling is solved so that at Vibration of the blades no bouncing noise occurs.

Ein Vorspannen der Haut vor den abzuschneidenden Bartstoppeln ist bei vibrierenden Klingen nicht erforderlich. Dagegen stellen sich vibrierende Klingensysteme als besonders hautschonend heraus, wenn die Gesichtshaut unmittelbar vor und hinter den Schnittkanten durch einen Gleitschuh gestützt und ruhig gestellt ist.Preloading the skin before cutting it Beard stubble is not necessary with vibrating blades. In contrast, vibrating blade systems pose as particularly gentle on the skin when the facial skin immediately in front of and behind the cut edges by a Is supported and immobilized.

Fig. 1: zeigt einen Gleitschuh (2) in Gestalt eines Röhrchens, in dessen Innern eine rund angeschmiegte, hauchdünne Klinge mit zwei Schnittkanten (1) unbeeinflußt vom Druck auf die Gesichtshaut longitudinal vibriert, der Gleitschuh dabei aber selbst und damit auch die von ihm berührte Gesichtshaut nahezu in Ruhe bleibt.Fig. 1: shows a slide shoe (2) in the form of a tube, inside of which a round, gossamer-thin blade with two cut edges (1) vibrates longitudinally, unaffected by the pressure on the facial skin, but the slide shoe itself and therefore also that of it touched facial skin remains almost at rest.

Das optional auch langsame, vorsichtige Führen dieses Klingenblocks über die Gesichtshaut ermöglicht gegenüber dem 'Ratschziehen' einer Handrasur sogar erstmalig zwei sinnvolle Schnittrichtungen (Ziehen und Schieben, vorteilhaft bei Haarwirbeln oder im Normalfall ungünstig in Ziehrichtung des Klingenblocks wachsenden Barthaaren).

  • (1) Rasierklinge mit zwei Schnittkanten (zum Ziehen und Schieben), im Gleitschuh (2) longitudinal vibrierfähig
  • (2) Gleitschuh, hier aus zwei Röhrchenhälften zusammengesetzt
  • (4) Schwingarm des Schwinggebers, mit zwei Klemmhaken (9) im länglichen Stanzloch der Klinge zu befestigen
  • (5) Schwenkradius des Klingenblocks
  • (6) Klingenblock aus zwei Röhrchen denkbar
  • (7) Öffnungen an den Röhrchenenden zum Ausspülen der Rasierreste
  • (8) Sprengringe an den Röhrchenenden zum Zusammenhalten der Röhrchenhälften, schützen auch die Gesichtshaut vor den Klingenecken
  • (9) Klemmhaken des Schwingarms (4), sind zum Lösen aus dem Stanzloch der Klinge zusammen zu drücken
  • (10) Gesichtshaut
  • The optional slow, careful guiding of this blade block over the skin of the face even allows for the first time two sensible cutting directions compared to 'ratcheting' a hand shave (pulling and pushing, advantageous for hair swirls or in the normal case unfavorably growing beard hair in the direction of pulling the blade block).
  • (1) Razor blade with two cut edges (for pulling and pushing), longitudinally vibratable in the sliding block (2)
  • (2) Slide shoe, here composed of two tube halves
  • (4) Swing arm of the transducer, to be fastened with two clamping hooks (9) in the elongated punch hole of the blade
  • (5) Swivel radius of the blade block
  • (6) Blade block conceivable from two tubes
  • (7) Openings at the ends of the tubes for rinsing out the shaving residue
  • (8) Snap rings on the tube ends to hold the tube halves together, also protect the facial skin from the blade corners
  • (9) Clamping hooks of the swing arm (4) must be pressed together to release them from the punched hole in the blade
  • (10) facial skin
  • Claims (1)

    1. Wet shaver with a gliding shoe (2) and a blade block put on a swinging arm (4) is characterized by a gliding shoe consisting of two small pipe halves held together on their ends and an extremely thin and flexible blade which shows two cutting edges of opposite direction vibrating inside the small pipe.
