Description
Die Erfindung betrifft von außen unsichtbare und beim Hochheben des Kopfteiles selbsttätig in jeder Höhenlage einstellbare und selbsttätig umschaltbare Lehnenstellvorrichtungen, von denen sich der Erfindungsgegenstand dadurch unterscheidet, daß eine einwandfreie und insbesondere ruhig gleitende Führung vorhanden ist. Dieses wird gemäß der Erfindung dadurch erreicht, daß der Stützhebel, welcher die aus dem gelenkig verbundenen Hebelpaar bestehende Lehnenstellvorrichtung in seiner Winkelstellung hält, an einem eine Sperrvorrichtung tragenden Schlitten angelenkt ist, der auf dem verzahnten Hebel des Hebelpaares läuft.The invention relates to invisible from the outside and when lifting the head part automatically adjustable and automatically switchable backrest adjustment devices at any height, from which the subject of the invention differs in that a flawless and, in particular, smoothly sliding Leadership is in place. This is achieved according to the invention in that the Support lever, which the backrest adjusting device consisting of the articulated pair of levers holds in its angular position, is hinged to a slide carrying a locking device, which is on the toothed Lever of the lever pair is running.
Dieser Schlitten wird in einfachster Weise gemäß der Erfindung aus einer den. verzahnten Hebel umfassenden U-förmig gebogenen Platte hergestellt, deren beide Schenkel, zwischen denen ein in die Verzahnung eingreifender Sperrzahn lose hängt, in Höhe des gezahnten Hebels durch ein Querstück miteinander verbunden sind.This carriage is in the simplest manner according to the invention from one of the. geared Lever comprising a U-shaped curved plate, both legs of which between which a ratchet tooth engaging in the toothing hangs loosely, at the level of the toothed lever are connected by a cross piece.
Der Erfindungsgegenstand ist in der Zeichnung in einem Ausführungsbeispiel dargestellt, und zwar zeigtThe subject of the invention is shown in the drawing in an exemplary embodiment, namely shows
Abb. ι die Mittelstütze bei niedergelegtem Kopfteil,Fig. Ι the central support with the headboard laid down,
Abb. 2 die Stütze mit hochgestelltem Kopfteil in Seitenansicht.Fig. 2 the support with the head part raised in a side view.
Von den beiden aneinandergelenkten Hebeln« und b ist der Hebel a gelenkig an dem Bettrahmen c befestigt, während der Hebel b gelenkig an dem Kopfteil d angebracht ist. An dem Hebel b ist ein dritter Hebel e angelenkt. Dieser Hebel ist gelenkig mit einem Schlitten ο verbunden, an dem anderseits eine Sperrklinke/ ebenfalls leicht beweglich gelenkig angeordnet ist. Dieser Schlitten besteht aus einer um den verzahnten Hebel α U-förmig herumgelegten Platte, zwischen deren Schenkeln dann die Bolzen ρ und q zur Anlenkung des Stützhebelse und der Klinke/ befestigt sind. Die Schenkel sind außerdem in Höhe des ver- <*5 zahnten Hebels α mit einem Querstück r verbunden. Hierdurch wird eine breite vollkommen geschlossene Führung für den verzahnten Hebel ff erzielt.Of the two mutually articulated levers 1 and b , the lever a is articulated to the bed frame c , while the lever b is articulated to the head part d . A third lever e is hinged to the lever b. This lever is connected in an articulated manner to a slide ο on which a pawl is arranged in an articulated manner, which is also easily movable. This carriage consists of a plate placed around the toothed lever α in a U-shape, between the legs of which the bolts ρ and q for the articulation of the support lever and the pawl / are fastened. The legs are also connected to a cross piece r at the level of the toothed lever α . As a result, a wide, completely closed guide for the toothed lever ff is achieved.
Die Längey der zahnförmigen Klinke/ ist länger als der Abstand χ des Bolzens q von der Verzahnung des Hebels a, so daß die Klinke / bei Aufwärtsbewegung über die Falle schleift, jedoch bei Abwärtsbewegung in die Verzahnung« eintritt und festgestellt wird.The length y of the tooth-shaped pawl / is longer than the distance χ of the bolt q from the toothing of the lever a, so that the pawl / slips over the latch when moving upwards, but enters the toothing when moving downward and is locked.
