Description

Es ist öfters notwendig, gegeneinander verschiebbare Teile miteinander zu verbinden; z. B. Stützen (Stempel), die zur Abstützung in Bergwerkstollen dienen. Das Verbinden und Lösen solcher Teile soll leicht und schnell bewerkstelliät werden, ahne Gewindestücke heranzuziehen; deren Verwendung unter den im Bergwerk herrschenden atmosphärischen Bedingungen nicht angezeigt ist.It is often necessary to mutually displaceable parts with one another connect to; z. B. Supports (stamps), which are used to support in mine tunnels. The connection and disconnection of such parts should be done quickly and easily, without using threaded pieces; their use among those prevalent in the mine atmospheric conditions is not indicated.

Gegenstand der Erfindung ist eine Spannvorrichtung, .die mittels einfacher Keile arbeitet. Die Vor-' richtung besteht aus einem U-förmigen Schuh; der die zu verbindenden Stücke an der Stelle, an der sie übereinanderliegen, umfaßt, und aus Keilen, die durch einander gegenüberliegende Öffnungen im Schuh getrieben werden. Dabei :werden die zu verbindenden Teile gegeneinander und gegen den Boden des Schuhes gedrückt.The invention relates to a clamping device, .the means of simple Wedges works. The device consists of a U-shaped shoe; who to connecting pieces at the point where they overlap, and from Wedges driven through opposing openings in the shoe. Thereby: the parts to be connected are against each other and against the bottom of the shoe pressed.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar.The drawing shows an embodiment of the invention.

Abb. i zeigt eine Seitenansicht des Verhindungsschuhes; Abb. 2 und 3 sind Schnitte der Abb. i nach der Linie A-B bzw. C-D.Fig. I shows a side view of the prevention shoe; Fig. 2 and 3 are sections of Fig. I along the line A-B and C-D.

Der Verbindungsschuh besteht aus einem aus Metall gefertigten Stück i mit Erleichterungslöchern 2. Zur Befestigung wird der Schuh an der Stelle angebracht, an der die zu verbindenden Teile 3 und 4 übereinanderliegen; im dargestellten Beispiel sind die zu verbindenden Teile zwei Hutprofile.The connecting shoe consists of a piece made of metal i with relief holes 2. The shoe is attached to the place where it is at which the parts to be connected 3 and 4 are superimposed; in the example shown the parts to be connected are two hat profiles.

Um eine verstellbare Verbindung zu erhalten, werden Keile 5 mehr oder weniger kräftig durch die einander gegenüberliegenden Öffnungen 6 und 7 in den Seitenwänden des Schuhes getrieben. Die Keile drücken die Stützen 3 und 4 gegeneinander und gegen den Boden des Schuhes.To obtain an adjustable connection, wedges 5 more or more less powerful through the opposing openings 6 and 7 in the side walls of the shoe driven. The wedges press the supports 3 and 4 against one another and against one another the bottom of the shoe.

PATENTANSPRUCH: Spannvorrichtung zur Verbindung gegeneinander verschiebbarer, nicht mit Gewinde versehener Teile, gekennzeichnet durch einen U-förmigen Schuh, der die zu verbindenden Teile da, wo sie übereinanderliegen, umfaßt und durch Keile, die durch einander gegenüberliegende Öffnungen in den Seitenwänden des Schuhes hindurchgetrieben werden, durch welche Maßnahme die zu verbindenden Teile mehr oder weniger stark gegeneinander und gegen den Boden des Schuhes getrieben werden. Claim: Clamping device for connecting mutually displaceable, non-threaded parts, characterized by a U-shaped shoe, which includes the parts to be connected where they are superimposed, and by wedges which are driven through opposing openings in the side walls of the shoe by which measure the parts to be connected are driven more or less strongly against each other and against the bottom of the shoe.
