Description

Die Erfindung betrifft eine Vorrichtung, bei einem Langhaarschneidegerät, zur übertragung der Antriebsbewegung eines Drehschwingungen ausführenden Hebels auf einen in der gleichen Bewegungsebene linear geführten, das hin- und hergehende Scherteil tragende Schlitten.The invention relates to a device, in a long-hair trimmer, for transmitting the drive movement of a lever that executes torsional vibrations to a slide that is linearly guided in the same plane of movement and carries the reciprocating shear part.

Bei einer bekannten Vorrichtung dieser Art (DE-GM 77 23 157) ist das abtriebseitige Hebelende mit einem geschlitzten Kopf versehen, der in eine Gabel eingreift, die mit dem hin- und hergehenden Scherteil mittelbar oder unmittelbar in Verbindung steht. Diese in mehreren Varianten seit langem übliche Antriebsverbindung hat mehrere Nachteile. Die Ausbildung des Hebelkopfes und der Gabel erfordert eine relativ hohe Präzision, um Klappergeräusche und daherrührende Abnutzung zu vermeiden. Andererseits wird durch die Relativbewegung zwischen Kopf und Gabel Reibungsenergie verbraucht und der federnde Eingriff zwischen diesen Bauelementen kann zu Amplitudenverlust des bewegten Scherteils führen. Schließlich neigt das bewegte Scherteil oder ein dieses tragender Schlitten od. dgl. aufgrund der relativ ungünstigen Lager- und Antriebsbedingungen zu Taumelbewegungen und daraus resultierenden Laufgeräuschen.In a known device of this type (DE-GM 77 23 157) the output end of the lever is provided with a slotted head which engages in a fork which is indirectly or directly connected to the reciprocating shear part. This drive connection, which has long been common in several variants, has several disadvantages. The design of the lever head and the fork requires a relatively high degree of precision in order to avoid rattling noises and wear and tear. On the other hand, the relative movement between the head and the fork consumes frictional energy and the resilient engagement between these components can lead to a loss of amplitude of the moving shear part. Finally, due to the relatively unfavorable bearing and drive conditions, the moving shear part or a carriage or the like carrying it tends to wobble and result in running noise.

Die Erfindung hat daher die Aufgabe, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der weder äußere Reibung auftritt, bei der Klapper- und Laufgeräusche vermieden sind und Amplitudenverluste nicht entstehen.The object of the invention is therefore to create a device of the type mentioned in the introduction in which neither external friction occurs, rattling and running noises are avoided and amplitude losses do not occur.

Erfindungsgemäß ist diese Aufgabe mit der im Kennzeichen des Anspruches 1 angegebenen Maßnahme gelöst.According to the invention, this object is achieved with the measure specified in the characterizing part of claim 1.

Für einen ruhigen Bewegungsablauf und eine möglichst geringe Beanspruchung der Filmscharniergelenke ist der Arm in vorteilhafter Weiterbildung der Erfindung etwa tangential zur Bewegungsbahn des hebelseitigen Gelenks und annähernd parallel zur Bewegungsbahn des schlittenseitigen Gelenkes gerichtet.In an advantageous further development of the invention, the arm is directed approximately tangentially to the movement path of the lever-side joint and approximately parallel to the movement path of the slide-side joint for a smooth movement sequence and the least possible strain on the film hinge joints.

Nach einem weiteren Vorteil der Erfindung ist der Arm in einem Ausschnitt des Schlittens angebracht, und zwar derart, daß das schlittenseitige Gelenk, vom Drehpunkt des Hebels gesehen, jenseits der Führung des Schlittens liegt. Daraus ergeben sich gedrängte Einbaumaße und Taumelbewegungen des Schlittens werden unterbunden. Für eine einfache Montage ist die aus dem Hebel, dem Arm und dem Schlitten bestehende Baugruppe zweckmäßigerweise einstückig aus begrenzt elastischem Kunststoff hergestellt und sind die Gelenke als Filmscharniergelenke ausgebildet.According to a further advantage of the invention, the arm is mounted in a cutout of the slide, in such a way that the slide-side joint, seen from the pivot point of the lever, lies beyond the guide of the slide. This results in compact installation dimensions and wobble movements of the slide are prevented. For simple assembly, the assembly consisting of the lever, the arm and the slide is expediently made in one piece from limited elastic plastic and the joints are designed as film hinge joints.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen:

  • Fig. 1 eine Frontansicht der Vorrichtung und
  • Fig. 2 .eine Ansicht längs der Schnittlinie II - II in Fig. 1
In the drawing, an embodiment of the invention is shown. Show it:
  • Fig. 1 is a front view of the device and
  • FIG. 2 shows a view along the section line II-II in FIG. 1

An einer Gehäusewand 1 des Langhaarschneidegerätes gemäß Fig. 1 ist das feststehende Scherteil 2 mit Hilfe einer abgewinkelten Platte 3 montiert.The fixed shaving part 2 is mounted on a housing wall 1 of the long hair trimmer according to FIG. 1 with the aid of an angled plate 3.

Das bewegliche Scherteil 4 ist auf einem hin- und herbeweglichen Schlitten 5 angebracht und mittels Bolzen_6 und 7 lagengesichert; zwei auf dem Schlitten abgestützte Schrauben-federn 8 und 9 drücken dieses Scherteil 4 gegen das feststehende Scherteil 2. Der Schlitten 5 ist auf einem Sims 10 und an einer Vertikalfläche 11 der Gehäusewand 1 gleitbar linear geführt. Zum Antrieb des Schlittens 5 ist an der Gehäusewand 1 ein zweiarmiger Hebel 12 an einem Bolzen 13 schwenkbar gelagert. Am unteren Ende 14 trägt der Hebel 12 eine Pfanne 15, in die der Antriebsstift 16 eines nicht dargestellten Motors mit hin- und hergehender Abtriebsbewegung eingreift. An seinem oberen Ende 17 ist der Hebel 12 über einen Arm 18 mit dem Schlitten 5 verbunden, wobei die Scharniere 19 und 20 als Filmscharniere ausgebildet sind. Der Arm 18 ist in einem Ausschnitt 21 des Schlittens 5 in der Weise angebracht, daß das schlittenseitige Gelenk 20 vom Drehpunkt (Bolzen 13) aus gesehen, jenseits der Führung des Schlittens 5 auf dem Sims 10 liegt, wie aus Fig. 1 ohne weiteres zu ersehen ist.The movable shear part 4 is mounted on a reciprocating carriage 5 and secured in position by means of bolts 6 and 7; two helical springs 8 and 9 supported on the slide press this shear part 4 against the fixed shear part 2. The slide 5 is slidably guided linearly on a ledge 10 and on a vertical surface 11 of the housing wall 1. To drive the carriage 5, a two-armed lever 12 is pivotally mounted on a bolt 13 on the housing wall 1. At the lower end 14, the lever 12 carries a pan 15, in which the drive pin 16 of a motor, not shown, engages with a reciprocating output movement. At its upper end 17, the lever 12 is connected to the carriage 5 via an arm 18, the hinges 19 and 20 being designed as film hinges. The arm 18 is mounted in a cutout 21 of the carriage 5 in such a way that the carriage-side joint 20, seen from the pivot point (bolt 13), lies beyond the guidance of the carriage 5 on the ledge 10, as is readily apparent from FIG. 1 is seen.

Der Arm 18 ist ferner etwa tangential zur Bewegungsbahn des hebelseitigen Gelenkes 19 und annähernd parallel zur Bewegungsbahn des schlittenseitigen Gelenkes 20 gerichtet. Schlitten 5, Arm 18 und Hebel 12 sind einstückig aus Kunststoff hergestellt.The arm 18 is also directed approximately tangentially to the movement path of the lever-side joint 19 and approximately parallel to the movement path of the slide-side joint 20. Carriage 5, arm 18 and lever 12 are made in one piece from plastic.
