Abstract

A vertically adjustable carrier for a vise comprises a vertical support tube and a mounting which can be secured to a work bench and which comprises two semicylindrical shells which embrace the support tube and which can be clamped together to fix the support tube in any desired vertical position. The shells extend downwardly from the mounting and define a cavity which accommodates a gas spring which abuts on one end on the support tube and on the other end on the bottom of the composed half shells and exerts an upwardly directed force on the support tube to ease its vertical movement.

Description

Die Erfindung bezieht sich auf einen höhenverstellbaren Träger für Schraubstöcke, Montageplatten und dergleichen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a height-adjustable support for vices, mounting plates and the like according to the preamble of patent claim 1.

Bei den beispielsweise aus dem DE-U-81 13 061 bekannten Trägern dieser Art ist das Tragrohr in einem längsgeschlitzten Führungsrohr angeordnet, das von den Bügeln der Haltevorrichtung umgriffen und beim Zusammenklemmen der Bügel in seinem Durchmesser verringert wird, so daß es das Tragrohr in jeder Lage festklemmen kann. Der geschlossene Boden des Führungsrohres bildet dabei die Abstützstelle für das untere Ende des Federelements. Bei diesem Träger muß der Innendurchmesser der Bügel zum Außendurchmesser des Führungsrohres und der Außendurchmesser des Tragrohres zum Innendurchmesser des Führungsrohres mit relativ engen Toleranzen hergestellt (bzw. ausgewählt werden, um einerseits eine leichtgängige Höhenverstellung nach dem Lockern der durch die Bügel gebildeten Klemmeinrichtung zu ermöglichen, jedoch andererseits eine große Klemmkraft ohne übermäßigen Kraftaufwand zu erzeugen. Durch die Notwendigkeit, verhältnismäßig enge Toleranzen an drei miteinander zusammenwirkenden Bauteilen einhalten zu müssen, ist die Herstellung vergleichsweise aufwendig.In the carriers of this type known from DE-U-81 13 061, for example, the support tube is arranged in a longitudinally slotted guide tube which is gripped by the brackets of the holding device and is reduced in diameter when the brackets are clamped together, so that it supports the support tube in each Can clamp position. The closed bottom of the guide tube forms the support point for the lower end of the spring element. With this carrier, the inside diameter of the bracket to the outside diameter of the guide tube and the outside diameter of the support tube to the inside diameter of the guide tube must be made (or selected to allow, on the one hand, a smooth height adjustment after loosening the clamping device formed by the bracket, but with relatively small tolerances On the other hand, the production of a large clamping force without excessive expenditure of force The production is comparatively complex due to the need to maintain comparatively narrow tolerances on three interacting components.

Der Erfindung liegt die Aufgabe zugrunde, einen Träger der genannten Art zu schaffen, der sich durch einen einfacheren und dadurch billigeren Aufbau auszeichnet und bei dem ein verhältnismäßig breites Toleranzband bei der Herstellung zugelassen werden kann.The invention has for its object to provide a carrier of the type mentioned, which is characterized by a simpler and therefore cheaper structure and in which a relatively wide tolerance band can be allowed in the manufacture.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Kennzeichens des Patentanspruchs 1 gelöst.This object is achieved by the features of the characterizing part of patent claim 1.

Der erfindungsgemäße Träger ist durch den Verzicht auf das Führungsrohr un die Übernahme dessen Aufgaben dadurch daß die Bügel und das Rohr zu einem Bauteilpaar von zwei den Hohlraum umschliessenden Halbschalen integriert sind, mit wesentlich geringerem Aufwand herstellbar als der bekannte Träger, da mit dem Wegfall des Führungsrohres nur noch die Toleranzpaarung zwischen dem Außendurchmesser des Tragrohres und dem Innendurchmesser der Bügel zu beachten ist. Werden die Bügel in Leichtmetall-Druckguß hergestellt, so ist normalerweise keine Bearbeitung der Innenflächen erforderlich.The carrier according to the invention can be produced by dispensing with the guide tube and taking over its tasks in that the brackets and the tube are integrated into a pair of components of two half-shells enclosing the cavity, with much less effort than the known carrier, since with the omission of the guide tube only the tolerance pairing between the outer diameter of the support tube and the inner diameter of the bracket must be observed. If the brackets are made in die-cast light metal, no machining of the inner surfaces is normally required.

Die beiden Bügel können einen unten geschlossenen Hohlraum begrenzen. Dabei kann jeder Bügel an seinem unteren Ende einen sich axial erstreckenden Fortsatz aufweisen, wobei die unteren Enden der zusammengesetzten Bügel durch ein die Fortsätze umgreifendes Bauteil zusammengehalten werden. Dieses Bauteil kann ein Federring sein, zu dessen Aufnahme in den Fortsätzen eine entsprechende Umfangsnut vorgesehen wird.The two brackets can delimit a cavity closed at the bottom. Each bracket can have an axially extending extension at its lower end, the lower ends of the assembled bracket being held together by a component encompassing the extensions. This component can be a spring ring, a corresponding circumferential groove is provided for receiving it in the extensions.

Die Innenflächen der Bügel können mit Vorsprüngen, vorzugsweise in Form von Umfangsrippen, versehen sein. Diese Vorsprünge können zur Abstützung des unteren Endes des Federelements oder auch als Anschlag für die Abwärtsbewegung des Tragrohres dienen, um beispielsweise ein Einklemmen einer Hand des Benutzers zwischen einem auf dem Träger montierten Gerät und der Haltevorrichtung zu verhindern. Es können mehrere Vorsprünge bzw. Umfangsrippen in einem axialen Abstand voneinander vorgesehen werden, wodurch die Möglichkeit besteht, im Bedarfsfall verschieden lange Federelemente einzusetzen bzw. den Anschlag für das Tragrohr in verschiedenen Höhen vorzusehen. Der Anschlag selbst wird durch eine in das von den Halbschalen gebildete Rohr eingelegte und auf den betreffenden Vorsprüngen bzw. Umfangsrippen aufliegende Scheibe gebildet, die gleichzeitig die Abstützung für die Gasfeder darstellen kann. Die Scheibe kann auch eine zentrale Öffnung aufweisen, durch die sich das Federelement erstreckt, wenn sich das untere Ende des Federelements auf dem Boden der Halbschalen abstützen soll.The inner surfaces of the brackets can be provided with projections, preferably in the form of peripheral ribs. These projections can serve to support the lower end of the spring element or also as a stop for the downward movement of the support tube, for example to prevent a user's hand from being caught between a device mounted on the carrier and the holding device. Several projections or circumferential ribs can be provided at an axial distance from one another, which makes it possible to use spring elements of different lengths if necessary or to provide the stop for the support tube at different heights. The stop itself is formed by a disk inserted into the tube formed by the half-shells and resting on the relevant projections or circumferential ribs, which disk can simultaneously represent the support for the gas spring. The disc may also have a central opening through which the spring element extends when the lower end of the spring element is to be supported on the bottom of the half-shells.

Alternativ kann anstelle der Vorsprünge in den von den Halbschalen umschlossenen Hohlraum ein Rohrabschnitt geeigneter Länge eingesetzt werden, der sich auf dem Boden des Hohlraumes abstützt und dessen oberes Ende als Anschlag für das Tragrohr bzw. als Abstützung für das untere Ende des Federelements dient.Alternatively, a tube section of suitable length can be used instead of the projections in the cavity enclosed by the half-shells, which is supported on the bottom of the cavity and whose upper end serves as a stop for the support tube or as a support for the lower end of the spring element.

Als Federelement wird vorzugsweise eine Gasfeder vorgesehen.A gas spring is preferably provided as the spring element.

Ein Ausführungsbeispiel der Erfindung wird im folgenden unter Bezugnahme auf die Zeichnung beschrieben. Es zeigt:

  • Fig. 1 eine Seitenansicht eines höhenverstellbaren Trägers, teilweise geschnitten,
  • Fig. 2 und 3 Schnitte entlang Linien 11-11 bzw. 111-111 in Fig. 1,
  • Fig. 4 einen Schnitt entlang Linie IV-IV in Fig. 2, und
  • Fig. 5 einen Schnitt ähnlich Fig. 3 eines Trägers mit einer abgewandelten Abstützung für das Federelement.
An embodiment of the invention is described below with reference to the drawing. It shows:
  • 1 is a side view of a height-adjustable carrier, partially in section,
  • 2 and 3 sections along lines 11-11 and 111-111 in Fig. 1,
  • Fig. 4 is a section along line IV-IV in Fig. 2, and
  • 5 shows a section similar to FIG. 3 of a carrier with a modified support for the spring element.

Der Träger weist ein senkrechtes Tragrohr 1 auf, das an seinem oberen Ende eine Platte 2 trägt, auf der ein Schraubstock, eine Montageplatte oder dergleichen befestigt werden kann. Eine an einem Werktisch anbringbare Haltevorrichtung 3 weist zwei Bügel 4 und 5 auf, welche das Tragrohr 1 umgreifen und von denen die Bügel 4 ortsfest ist und einen Ansatz 6 aufweist, mit dem die Haltevorrichtung 3 an dem Werktisch befestigt werden kann, während der Bügel 5 relativ zum Bügel 4 beweglich ist. Die beiden Bügel 4 und 5 sind auf der einen Seite durch zwei Abstützschrauben 7 und auf der anderen Seite durch eine Klemmschraube 8 mit Handgriff 9 miteinander verbunden. Durch Festziehen der Klemmschraube 8 werden die beiden Bügel 4 und 5 zusammengespannt und klemmen das Tragrohr 1 in jeder beliebigen Lage fest.The carrier has a vertical support tube 1, which carries at its upper end a plate 2 on which a vice, a mounting plate or the like can be attached. A holding device 3 that can be attached to a work table has two brackets 4 and 5, which encompass the support tube 1 and of which the bracket 4 is stationary and has an extension 6 with which the holding device 3 can be fastened to the work table while the bracket 5 is movable relative to the bracket 4. The two brackets 4 and 5 are connected on one side by two support screws 7 and on the other side by a clamping screw 8 with a handle 9. By tightening the clamping screw 8, the two brackets 4 and 5 are clamped together and clamp the support tube 1 fixed in any position.

Die beiden Bügel 4 und 5 erstrecken sich von der Haltevorrichtung 3 nach unten und begrenzen einen Hohlraum 10, in dem eine Gasfeder 11 angeordnet ist. Die Gasfeder 11 besteht aus einem Zylinder 12, einem Kolben 13 und einer von diesem ausgehenden Kolbenstange 14 und weist einen Zylinderraum 15 auf, der ein unter hohem Druck stehendes Gas enthält. Das obere Ende der Gasfeder 11, im dargestellten Ausführungsbeispiel das Ende der Kolbenstange 14, stützt sich auf der Unterseite der mit dem Tragrohr 1 verbundenen Platte 2 ab, während ihr unteres Ende, also das untere Ende des Zylinders 12, auf einer Scheibe 16 aufliegt, die formschlüssig in das von den Bügel 4 und 5 gebildete Rohr eingesetzt ist. Zu diesem Zweck sind Umfangsrippen 17, 18 an den Innenwänden der Bügel 4, 5 vorgesehen, auf denen die Scheibe 16 aufliegt. Im Ausführungsbeispiel sind drei Umfangsrippen in einem axialen Abstand voneinander vorgesehen, um Gasfedern unterschiedlicher Länge unterbringen zu können. Die Gasfeder 11 kann sich auch am unteren Ende oder Boden 19 der Bügel 4, 5, abstützen. Die Scheibe 16 dient gleichzeitig als Anschlag zur Begrenzung der Abwärtsbewegung des Tragrohres 1, um ein Einklemmen einer Hand des Benutzers zwischen der Platte 2 und dem Ansatz 6 bzw. dem Werktisch zu verhindern. Die Scheibe 16 kann mit einer zentralen Öffnung versehen sein, durch die sich die Gasfeder 16 hindurcherstrecken kann, wenn die Scheibe 16 nur als Anschlag für das Tragrohr 1 dienen und die Gasfeder sich am Boden 19 abstützen soll. Die beiden Bügel 4, 5 weisen an ihren unteren Enden je einen axial sich erstreckenden Fortsatz 20 bzw. 21 mit einer Umfangsnut 22 auf, in die ein Federring 23 eingesetzt ist, der die unteren Enden der Bügel 4, 5 zusammenhält.The two brackets 4 and 5 extend downward from the holding device 3 and delimit a cavity 10 in which a gas spring 11 is arranged. The gas spring 11 consists of a cylinder 12, a piston 13 and a piston rod 14 extending therefrom and has a cylinder chamber 15 which contains a gas under high pressure. The upper end of the gas spring 11, in the exemplary embodiment shown the end of the piston rod 14, is supported on the underside of the plate 2 connected to the support tube 1, while its lower end, that is to say the lower end of the cylinder 12, rests on a disk 16, which is positively inserted into the tube formed by the bracket 4 and 5. For this purpose, circumferential ribs 17, 18 are provided on the inner walls of the brackets 4, 5, on which the disc 16 rests. In the exemplary embodiment, three circumferential ribs are provided at an axial distance from one another in order to be able to accommodate gas springs of different lengths. The gas spring 11 can also be supported at the lower end or bottom 19 of the brackets 4, 5. The disc 16 also serves as a stop to limit the downward movement of the support tube 1 in order to prevent a hand of the user from getting caught between the plate 2 and the extension 6 or the work table. The disc 16 can be provided with a central opening through which the gas spring 16 can extend if the disc 16 is only used as a stop for the support tube 1 and the gas spring is to be supported on the bottom 19. At their lower ends, the two brackets 4, 5 each have an axially extending extension 20 or 21 with a circumferential groove 22, into which a spring ring 23 is inserted, which holds the lower ends of the brackets 4, 5 together.

Anstelle der Umfangsrippen 17, 18 können natürlich auch einzelne warzenartige Vorsprünge in einer bzw. in mehreren Ebenen vorgesehen werden.Instead of the circumferential ribs 17, 18, of course, individual wart-like projections can also be provided in one or in several planes.

Wie aus Fig. 3 ersichtlich ist, überlappen sich die Ränder 24, 25 der beiden Bügel 4, 5 außerhalb des Klemmbereiches. Damit wird erreicht, daß der Hohlraum 10 verhältnismäßig dicht abgeschlossen ist, wodurch die Verschmutzungsgefahr verringert ist.As can be seen from FIG. 3, the edges 24, 25 of the two brackets 4, 5 overlap outside the clamping area. It is thereby achieved that the cavity 10 is closed relatively tight, whereby the risk of contamination is reduced.

Fig. 5 zeigt eine Abwandlung des Ausführungsbeispiels gemäß Fig. 1 bis 4, und zwar ist hier anstelle der Umfangsrippen 17, 18 in den Hohlraum 10 ein Rohrabschnitt 26 eingesetzt, der auf dem Boden 19 des Hohlraumes 10 aufliegt und dessen oberes Ende über die Scheibe 16 als Abstützung für das untere Ende der Gasfeder 11 und als Anschlag für das Tragrohr 1 dient.Fig. 5 shows a modification of the embodiment of FIGS. 1 to 4, namely that instead of the circumferential ribs 17, 18 in the cavity 10, a pipe section 26 is used, which rests on the bottom 19 of the cavity 10 and its upper end over the disc 16 serves as a support for the lower end of the gas spring 11 and as a stop for the support tube 1.

Selbstverständlich sind viele Abwandlungen des dargestellten Ausführungsbeispiels möglich, ohne den Rahmen der Erfindung zu verlassen. So kann anstelle einer Gasfeder auch ein anderes Federelement, z. B. eine Schraubendruckfeder, vorgesehen werden. Die Bügel 4, 5 brauchen auch keinen abgeschlossenen Hohlraum zu begrenzen, obgleich dies aus Gründen der Arbeitssicherheit und zur Verringerung der Verschmutzungsgefahr bevorzugt ist. Zur Eingrenzung der Toleranzen kann das Tragrohr 1 kalibriert sein.Of course, many modifications of the illustrated embodiment are possible without leaving the scope of the invention. So instead of a gas spring, another spring element, for. B. a helical compression spring can be provided. The brackets 4, 5 also do not need to limit a closed cavity, although this is preferred for reasons of occupational safety and to reduce the risk of contamination. To limit the tolerances, the support tube 1 can be calibrated.
