Description

Die Erfindung betrifft eine Feststellvorrichtung für Kopfstützen an Friseurstühlen.The invention relates to a locking device for headrests Barber chairs.

Die bisher bekanntgewordenen Kopfstützen sind in ihrer Art der Verstellung sehr verschieden. Grundsätzlich ist, daß sie mittels einer runden oder flachen Stange nach oben und unten verstellbar sind und um eine waagerechte Achse in einem Gelenkkopf bewegt werden können. Das Feststellen in bestimmten Lagen geschieht durch Stellstifte, Schnepper-, Rast- oder Arretierhebel. Alle Arten dieser Feststellung sind mehr oder weniger einer frühzeitigen Abnutzung ausgesetzt, so daß ein einwandfreies Feststellen nicht mehr gewährleistet'ist.The previously known headrests are in their type of adjustment very different. Basically it is done by means of a round or flat bar are adjustable up and down and around a horizontal axis in a joint head can be moved. The fixing in certain positions is done by setting pins, Snap, detent or locking lever. All types of this finding are more or less less exposed to premature wear, so that a perfect locking is no longer guaranteed.

Demgegenüber besteht .das Wesen der Erfindung darin, daß .die Verstellung der Kopfstütze in ihren beiden Verstellarten ohne jegliche Betätigung von Verstellstift, Schnepper-, Rast- oder Arretierhebel geschieht, sondern nur durch einen einfachen Druck mit der Hand in die gewünschte Verstellrichtung. Das Feststellen wird durch eine in einem Federgehäuse unter Federdruck ruhende Stahlkugel bewirkt. Die Feder drückt unter Federspannung die Kugel an die festzuhaltende Stange oder den Gelenkkopf, so daß diese dort in die vorhandenen Rastbohrungen einrastet. Ein Festhalten ist daher immer gewährleistet, da eine Abnutzung kaum stattfindet.In contrast, the essence of the invention is that the adjustment the headrest in its two types of adjustment without any actuation of the adjustment pin, Snap, detent or locking lever happens, but only by a simple one Hand pressure in the desired direction of adjustment. The determination is made by causes a steel ball resting in a spring housing under spring pressure. The feather presses the ball against the rod to be held or the joint head under spring tension, so that it snaps into the existing locking bores. Holding on is therefore always guaranteed, since there is hardly any wear and tear.

Ein Ausführungsbeispiel der Erfindung soll an Hand der Zeichnung beschrieben werden. Mit a ist der Gelenkkopf mit Stange bezeichnet, an dem in ,bekannter Weise die Kopfstütze b gelenkartig befestigt ist, so daß sie nach hinten und vorn verstellt werden. kann.An embodiment of the invention will be described with reference to the drawing will. With a, the joint head with rod is referred to, on which in a known manner the headrest b is hinged so that it can be adjusted back and forth will. can.

In den Haltebock c kann die Kopfstütze b mit dem Gelenkkopf a nach oben und unten verstellt werden. Für die Feststellung der Kopfstütze in beiden Verstellarten ist an dem Bügel d und Haltebock c eine in einem Federgehäuse unter Federdruck befindliche Stahlkugel f angebracht. An dem Gelenkkopf und der Stange a sind die Rastlöcher g erkennbar, in welche die Stahlkugel f einrastet. Bei einem bestimmten Druck in der Verstellrichtung wird die Kugel zurückgedrückt und rastet dann an beliebiger Stelle wieder ein.In the bracket c, the headrest b with the joint head a can after can be adjusted at the top and bottom. For fixing the headrest in both types of adjustment is on the bracket d and bracket c located in a spring housing under spring pressure Steel ball f attached. The locking holes are on the joint head and the rod a g can be seen in which the steel ball f engages. At a certain pressure in the adjustment direction, the ball is pushed back and then engages with any Hire again.
