Description
Vorrichtung zum Ein- und Feststellen von Wandarmtischen, besonders für zahnärztliche Zwecke. Bei Wandarmtischen, welche beispielsweise von Zahnärzten :gebraucht werden, macht sich der Übelstand ,geltend, daß die wagerechte Einstellung des Tisches auf Schwierigkeiten stößt, wenn beispielsweise der Halter des Wandarmes an der Wand nicht genau senkrecht angebracht werden kann oder ist.Device for setting and locking wall arm tables, especially for dental purposes. For wall arm tables, which are used by dentists, for example : are needed, the evil asserts itself that the horizontal adjustment of the table encounters difficulties, for example when the holder of the wall bracket cannot or is not mounted exactly vertically on the wall.
Diesem übels,tande zu begegnen, soll gemäß der Erfindung dadurch erreicht werden, daß der an der Unterseite des Tisches angeordnete Tragzapfen, der in bekannter Weise in einer entsprechenden Bohrung am- Ende des Tragarmes gelagert ist, mittels geeigneter, beiderseits dies Tragarmes angreifender und entgegengesetztgerichtete Kugelflächen tragender Klemmkörper in wagerechter Lage- genau ein-und festgestellt werden kann.To counteract this evil is to be achieved according to the invention be that the arranged on the underside of the table support pin, which is known in Way is mounted in a corresponding hole at the end of the support arm, by means of more suitable, attacking on both sides of this support arm and facing in the opposite direction Clamping bodies carrying spherical surfaces in a horizontal position - precisely inserted and fixed can be.
Die Einrichtung ist in einem Ausführungsbeispiel in, der Zeichnung dargestellt, und zwar zeigt Abb. r den Wandarm nebst Tisch in Seitenansicht, Abb. z einen teilweisen Schnitt durch den vorderen Teil des den Tisch tragenden Wandarmes und Abb. 3 einen senkrechten Schnitt bei anderer Einstellung des Tisches gegenüber dem Wandarm.The device is in one embodiment in, the drawing shown, namely Fig.r shows the wall arm together with the table in side view, Fig. z a partial section through the front part of the wall arm supporting the table and Fig. 3 is a vertical section with a different setting of the table opposite the wall arm.
Der Tisch a, der beispielsweise von' Zahnärzten benutzbar ist, ist auf einem Träger b befestigt, an welchen sich ein Zapfen n ansetzt. Der eigentliche Wandarm besteht aus den beiden zur Hocheinstellung dienenden Parallelhebeln e, f, welche drehbar an der Drehachse g angebracht sind. Diese ruht in La-gern h, i, die an der ZVandplatte k befestigt sind. Diese Platte wird in geeigneter Weise an derWandm befesRigt. Die vorderen Enden der Hebel e, f tragen eine Führungsscheibe d, welche der Schiene c als Lager dient. Diese Schiene c ist in dem Lager längsverschiebbar und trägt am vorderen Ende eine Bohrung s, durch welche der Zapfen n hindurchgeht. Die Bohrung ist am oberen und unteren Ende halbkugelförmig bei t und ia ausgeweitet, und in diese halbkugelförmigen Lagerflächen legen sich zwei Halbkugelringe o und p. Diese Halbkugelringe werden miteinander verbunden und gegen die halbkugelförmigen Lagerflächen t und u durch eine Mutter r gedrückt, welche auf das freie Ende des Zapfens n aufgeschraubt wird.The table a, which can be used, for example, by dentists, is attached to a support b on which a pin n is attached. The actual wall arm consists of the two parallel levers e, f which are used for high adjustment and which are rotatably attached to the axis of rotation g. This rests in bearings h, i, which are attached to the ZVandplatte k. This plate is attached to the wall in a suitable manner. The front ends of the levers e, f carry a guide disk d, which serves as a bearing for the rail c. This rail c is longitudinally displaceable in the bearing and has a bore s at the front end through which the pin n passes. The bore is widened hemispherically at the upper and lower ends at t and ia, and two hemispherical rings o and p are placed in these hemispherical bearing surfaces. These hemispherical rings are connected to one another and pressed against the hemispherical bearing surfaces t and u by a nut r which is screwed onto the free end of the pin n.
Die mit l bezeichnete Wand ist nicht senkrecht, sondern etwas schräg gezeichnet, um darzutun, daß diesen Verschiedenheiten der Wandflächen entsprechend der Tisch a wagerecht einAellbar sein muß.The wall marked l is not vertical, but rather inclined drawn to show that these differences in wall surfaces correspond the table must be adjustable horizontally.
Die Abb. z läßt erkennen, daß die Achse des Zapfens n und die Achse der Schiene c senkrecht zueinander stehen, während nach Abb.3 diese beiden Achsen nicht im senkrechten Winkel zueinander sich befinden, da der Tisch a entsprechend der schrägen Fand l anders hat eingestellt werden müssen. Dies ist dadurch ermöglicht, daß die Halbkugelringe o und p eine verschiedene Lage in den entsprechenden Lagerflächen t und u einnehmen können.Fig. Z shows that the axis of the pin n and the axis of the rail c are perpendicular to each other, while according to Fig. 3 these two axes are not at a perpendicular angle to each other, since the table a is different according to the inclined Fand l must be set. This is made possible by the fact that the hemispherical rings o and p can assume a different position in the corresponding bearing surfaces t and u .
v ist ,eine Stellschraube zur Sicherung des Tisches a gegen Drehung um den Zapfen n. v is a set screw to secure the table a against rotation about the pin n.
