- Height-adjustable tables of this type (but also height-adjustable chairs) are known in which spring arrangements with weight compensation or so-called gas springs serve as energy stores in order to be able to carry out the desired height adjustment.
- Blocking devices serve to secure the altitude reached in each case in that the force effect of the lifting device is blocked.
- a lever is provided as the triggering device, which is pivotally mounted below the table top or below the seat surface and with one end e.g. presses on an actuating pin of a valve when the lever is gripped by hand at the other end.
- the innovation is based on the task of avoiding this disadvantage.
- the triggering device is provided with a switch button arranged in the table surface.
- the switch button is designed as a bolt which can be displaced in a hole in the table top and is operatively connected to the blocking device of the lifting device arranged below the table top. This configuration makes it possible in a very simple manner to use known lifting devices which contain their blocking devices and the release devices for this purpose.
- a gas spring consisting of a piston / cylinder unit is provided as the lifting device and is equipped with a blocking valve serving as a blocking device, the bolt leading downward through the table plate can directly actuate a release pin of this blocking valve.
- the upper end face of the bolt is in alignment with the table surface when not actuated.
- the smooth, continuous table surface can be maintained.
- the diameter of the bolt is advantageously adjusted approximately to the diameter of the cylinder of the gas spring, so that its axis is aligned with the axis of the gas spring and with a release pin of the blocking valve which is arranged on the gas spring axis and is pressed by spring force against the bolt.
- the cylinder of the gas spring is firmly connected to the tubular part connected to the table top and the piston rod is connected to the tubular part fixed to the foot of the table.

Abstract
Description
Die Neuerung betrifft einen höhenverstellbaren Tisch, insbesondere einen Einsäulentisch mit einer Tischplatte, der als Standfuß teleskopartig ineinander geführte Rohrteile zugeordnet sind, die von einer mit einer Blockiereinrichtung versehenen Hebeeinrichtung gegeneinander verschiebbar sind, wobei die Betätigung der Blockiereinrichtung über eine von Hand zu betätigende Auslöseeinrichtung erfolgt. Höhenverstellbare Tische dieser Art (aber auch höhenverstellbare Stühle) sind bekannt, bei denen Federanordnungen mit Gewichtsausgleich oder sog. Gasfedern als Kraftspeicher dienen, um die gewünschte Höhenverstellung vornehmen zu können. Blockiereinrichtungen dienen dabei dazu, die jeweils erreichte Höhenlage dadurch zu sichern, daß die Kraftwirkung der Hebeeinrichtung gesperrt wird. Bei bekannten Tisch- und Stuhleinrichtungen wird dabei als Auslöseeinrichtung ein Hebel vorgesehen, der unterhalb der Tischplatte oder unterhalb der Sitzfläche schwenkbar gelagert ist und mit einem Ende z.B. auf einen Betätigungsstift eines Ventiles drückt, wenn der Hebel am anderen Ende von Hand erfaßt wird.The innovation relates to a height-adjustable table, in particular a single-column table with a table top, which is assigned as a base telescopically guided tube parts which can be moved against each other by a lifting device provided with a blocking device, the blocking device being actuated via a manually operated trigger device. Height-adjustable tables of this type (but also height-adjustable chairs) are known in which spring arrangements with weight compensation or so-called gas springs serve as energy stores in order to be able to carry out the desired height adjustment. Blocking devices serve to secure the altitude reached in each case in that the force effect of the lifting device is blocked. In known table and chair devices, a lever is provided as the triggering device, which is pivotally mounted below the table top or below the seat surface and with one end e.g. presses on an actuating pin of a valve when the lever is gripped by hand at the other end.
Diese Anordnungen sind insbesondere bei ihrem Einsatz für höhenverstellbare Tische insofern umständlich zu bedienen, als zu einer Höhenverstellung jeweils unter den Tisch gegriffen werden muß.These arrangements are particularly cumbersome to use when used for height-adjustable tables insofar as a height adjustment must be reached under the table.
Der Neuerung liegt die Aufgabe zugrunde, diesen Nachteil zu vermeiden. Zur Lösung wird bei einem Tisch der eingangs genannten Art vorgesehen, daß die Auslöseeinrichtung mit einem in der Tischfläche angeordneten Schaltknopf versehen ist. Durch diese Ausgestaltung kann die Höhenverstellung in einfacher Weise durch Drücken des von oben zugängigen Schaltknopfes vorgenommen werden. Eine vorteilhafte Weiterbildung der Neuerung sieht vor, daß der Schaltknopf als ein in einer Bohrung der Tischplatte verschiebbarer Bolzen ausgebildet ist, der mit der unterhalb der Tischplatte angeordneten Blockiereinrichtung der Hebeeinrichtung in Wirkverbindung steht. Diese Ausgestaltung erlaubt es in sehr einfacher Weise, auf bekannte Hebeeinrichtungen zurückzugreifen, die ihre Blockiereinrichtungen und die Auslöseeinrichtungen dazu unmittelbar enthalten. Wird nach Anspruch 3 als Hebeeinrichtung eine aus einer Kolben/Zylindereinheit bestehende Gasfeder vorgesehen, die mit einem als Blockiereinrichtung dienenden Blockierventil ausgerüstet ist, so kann der durch die Tischplatte nach unten führende Bolzen unmittelbar einen Auslösestift dieses Blockierventils betätigen.The innovation is based on the task of avoiding this disadvantage. To solve this problem, it is provided in a table of the type mentioned at the outset that the triggering device is provided with a switch button arranged in the table surface. With this configuration, the height adjustment can be carried out in a simple manner by pressing the switch button accessible from above. An advantageous further development of the innovation provides that the switch button is designed as a bolt which can be displaced in a hole in the table top and is operatively connected to the blocking device of the lifting device arranged below the table top. This configuration makes it possible in a very simple manner to use known lifting devices which contain their blocking devices and the release devices for this purpose. If, according to
In vorteilhafter Weiterbildung der Neuerung fluchtet die obere Stirnfläche des Bolzens im nicht betätigten Zustand mit der Tischoberfläche. Die glatte, durchgehende Tischfläche kann dadurch beibehalten werden. Der Durchmesser des Bolzens wird vorteilhaft in etwa dem Durchmesser des Zylinders der Gasfeder angeglichen, so daß seine Achse mit der Achse der Gasfeder und mit einem auf der Gasfederachse angeordneten, durch Federkraft gegen den Bolzen gedrückten Auslösestift des Blockierventiles fluchtet. Diese Ausgestaltung ergibt eine kompakte Anordnung der verschiebbaren Rohrteile, die sehr raumsparend ist, und sie erlaubt es auch nach Anspruch 7, den Auslösestift und den Bolzen über ein Gewinde fest miteinander zu verbinden, so daß der Bolzen in seiner Lage gesichert ist, und auch nicht nach oben aus der Tischplatte herausziehbar ist.In an advantageous development of the innovation, the upper end face of the bolt is in alignment with the table surface when not actuated. The smooth, continuous table surface can be maintained. The diameter of the bolt is advantageously adjusted approximately to the diameter of the cylinder of the gas spring, so that its axis is aligned with the axis of the gas spring and with a release pin of the blocking valve which is arranged on the gas spring axis and is pressed by spring force against the bolt. This configuration results in a compact arrangement of the displaceable tube parts, which is very space-saving, and it also allows according to claim 7, the release pin and the bolt to be firmly connected to each other via a thread, so that the bolt is secured in its position, and also not can be pulled up out of the table top.
In einer einfacher, Ausführung ist der Zylinder der Gasfeder fest mit dem mit der Tischplatte verbundenen Rohrteil und die Kolbenstange mit dem am Fuß des Tisches festen Rohrteil verbunden. Der Bolzen ragt bei dieser Ausführungsform in den oberen Teil des mit der Tischplatte verbundenen Rohrteiles herein. Er kann in einer in der Tischplatte angeordneten Buchse geführt und mit einem Anschlag versehen sein, der an der Unterseite der Buchse anliegt. Die fluchtende Position seiner Stirnseite an der Tischoberfläche, kann damit unabhängig von der Lage des Auslösestiftes gesichert werden.In a simple version, the cylinder of the gas spring is firmly connected to the tubular part connected to the table top and the piston rod is connected to the tubular part fixed to the foot of the table. In this embodiment, the bolt projects into the upper part of the tube part connected to the table top. It can be guided in a socket arranged in the table top and can be provided with a stop which rests on the underside of the socket. The aligned position of its front side on the table surface can be secured regardless of the position of the trigger pin.
Die Neuerung ist anhand eines Ausführungsbeispieles in den beigefügten Zeichnungen dargestellt, und wird im folgenden erläutert. Es zeigt
- Fig. 1
- einen schematischen Längsschnitt durch einen höhenverstellbaren Einsäulentisch nach der Neuerung, in der eingefahrenen niedrigsten Stellung, und
- Fig. 2
- den höhenverstellbaren Tisch der Fig. 1, jedoch in der ausgefahrenen, höchsten Stellung.
- Fig. 1
- a schematic longitudinal section through a height-adjustable single column table according to the innovation, in the retracted lowest position, and
- Fig. 2
- the height-adjustable table of FIG. 1, but in the extended, highest position.
Aus den Fig. 1 und 2 ist zu erkennen, daß der höhenverstellbare Tisch (1) eine Tischplatte (2) besitzt, die an einem zentralen Standfuß (3) gehalten ist. Der Standfuß (3) besteht aus einem auf dem Boden aufstellbaren plattenartigen Sockel (4), der fest mit einer rohrförmigen Standhülse (5) verbunden ist. Die Standhülse (5) ist mit einer Gleitbuchse (6) versehen, in der wiederum ein Gleitrohr (7) geführt ist, in das am oberen Ende eine Buchse (8) fest eingesetzt ist, die mit einem Flansch (9) auf der Oberkante des Gleitrohres (7) aufliegt, und mit diesem fest mit der Tischplatte (2) verschraubt ist. Über zwei Halteringe (10, 11) ist in das Gleitrohr (7) der Zylinder (12) einer an sich bekannten Gasfeder eingesetzt, der damit fest mit dem Gleitrohr (7) verbunden ist. Die Kolbenstange (13) der Gasfeder ragt unten aus deren Zylinder (12) vor, und ist fest mit dem Sockel (4) und dem Standrohr (5) verbunden. Tritt die Gasfeder daher in Aktion, so wird die Kolbenstange (13) unten aus dem Zylinder (12) herausgeschoben. Dadurch kann das Gleitrohr (7), und mit diesem die Tischplatte (2) nach oben verschoben werden, bis in die in Fig. 2 gezeigte Endlage.1 and 2 that the height-adjustable table (1) has a table top (2) which is held on a central base (3). The base (3) consists of a plate-like base (4) that can be set up on the floor and is firmly connected to a tubular stand sleeve (5). The stand sleeve (5) is provided with a sliding bush (6), in which in turn a sliding tube (7) is guided, into which a bushing (8) is firmly inserted at the upper end, which has a flange (9) on the upper edge of the Slide tube (7) rests, and is firmly screwed to the table top (2). The cylinder (12) of a gas spring known per se is inserted into the sliding tube (7) via two retaining rings (10, 11) and is thus firmly connected to the sliding tube (7). The piston rod (13) of the gas spring protrudes from the bottom of its cylinder (12), and is fixed to the Base (4) and the standpipe (5) connected. If the gas spring therefore comes into action, the piston rod (13) is pushed out of the cylinder (12) at the bottom. As a result, the sliding tube (7), and with it the table top (2), can be shifted up to the end position shown in FIG. 2.
Um Zwischenlagen in der Höhe der Tischplatte (2) einstellen zu können, ist die aus dem Zylinder (12) und der Kolbenstange (13) bestehende Gasfeder in ihrem Inneren in bekannter Weise mit einem Blockierventil versehen, das eine weitere Verschiebung des mit der Kolbenstange (13) verbundenen, aber nicht gezeigten Kolbens im Inneren des Zylinders (12) verhindert. Dieses Blokkierventil besitzt einen Auslösestift (14), der aus der der Kolbenstange (13) abgewandten Stirnseite des Zylinders (12) mittig nach oben heraussteht, und durch eine ebenfalls nicht gezeigte Feder in dieser herausstehenden Lage gehalten ist. Der Auslösestift (14) ist mit einem Gewinde in ein korrespondierendes Gewinde (15) eines zylindrischen Bolzens (16) eingeschraubt, dessen Durchmesser dem Innendurchmesser der Buchse (8) so angepaßt ist, daß sich der Bolzen (16) leicht innerhalb der Buchse axial in Richtung der Achse (17) des Standfußes (3) verschieben läßt. Der Bolzen (16) fluchtet mit seiner oberen Stirnfläche (16a) mit der Oberseite (2a) der Tischplatte, und er dient mit dieser Stirnfläche (16a) als Schaltknopf für die Auslösung des Blockierventils, das im Inneren des Zylinders (12) der Gasfeder angeordnet ist. Das Blockierventil wird dabei gelöst, wenn auf die Stirnfläche (16a) von einer Bedienungsperson gedrückt wird. Der Bolzen (16) wird dann nach unten verschoben und drückt den Auslösestift (14) in das Innere des Zylinders (12). Die Kolbenstange (13) wird dann unter dem Innendruck der Gasfeder aus dem Zylinder (12) herausgeschoben. Sie kann in jeder Position über das Blockierventil wieder arretiert werden, wenn nicht mehr auf die Stirnfläche (16a) des Bolzens (16) gedrückt wird, so daß dieser wieder die in der Fig. 1 (und Fig. 2) gezeigte Endlage einnimmt, in der seine Stirnfläche (16a) mit der Oberfläche (2a) der Tischplatte (2) fluchtet.In order to be able to set intermediate positions at the height of the table top (2), the gas spring consisting of the cylinder (12) and the piston rod (13) is provided in its interior in a known manner with a blocking valve, which further displaces the piston rod ( 13) connected but not shown piston inside the cylinder (12) prevented. This blocking valve has a release pin (14) which protrudes upwards from the end of the cylinder (12) facing away from the piston rod (13) and is held in this protruding position by a spring (also not shown). The trigger pin (14) is screwed with a thread into a corresponding thread (15) of a cylindrical bolt (16), the diameter of which is adapted to the inside diameter of the bush (8) in such a way that the bolt (16) easily axially within the bush Can move direction of the axis (17) of the base (3). The bolt (16) is aligned with its upper end face (16a) with the top (2a) of the table top, and with this end face (16a) it serves as a switch button for triggering the blocking valve, which is arranged inside the cylinder (12) of the gas spring is. The blocking valve is released when an operator presses the end face (16a). The bolt (16) is then moved downward and presses the release pin (14) into the interior of the cylinder (12). The piston rod (13) is then pushed out of the cylinder (12) under the internal pressure of the gas spring. It can be locked in any position via the blocking valve if no longer is pressed onto the end face (16a) of the bolt (16) so that it again assumes the end position shown in FIG. 1 (and FIG. 2) which aligns its end face (16a) with the surface (2a) of the table top (2).
Beim Ausführungsbeispiel ist der Durchmesser des Bolzens (16) etwas größer als der Durchmesser des Zylinders (12) gewählt. Der Bolzen (16) ragt mit seinem oberen Ende durch eine Bohrung (18) in der Tischplatte (2) hindurch. Er kann durch die gewählte Anordnung in sehr einfacher Weise in der ohnehin zur Befestigung der Tischplatte (2) an dem Gleitrohr (7) notwendigen Flanschbuchse nach innen geführt werden, um den dort befindlichen Auslösestift (14) zu betätigen. Es ergibt sich auf diese Weise eine kompakte, fluchtend zur Achse (17) ausgerichtete Gesamtanordnung. Die Anordnung der Betätigungsstirnfläche (16a) in der Mitte der Tischplatte (2) - bei der gewählten Einsäulenausführung - bringt auch noch den Vorteil mit sich, daß ein ästhetisches Bild der Tischoberfläche erreicht werden kann. So kann der Bolzen (16) beispielsweise, zumindest an seiner Oberseite (16a) mit einem Furnier versehen werden, das dem Furner der Tischplatte (2) entspricht. Natürlich kann auch eine Anpassung an andere Materialien erfolgen. Auch ein optisches Absetzen der Oberfläche (16a) durch bewußte Wahl anderer Materialien ist möglich.In the exemplary embodiment, the diameter of the bolt (16) is selected to be somewhat larger than the diameter of the cylinder (12). The bolt (16) protrudes with its upper end through a hole (18) in the table top (2). Due to the selected arrangement, it can be guided inwards in the flange bushing which is anyway necessary for fastening the table top (2) to the slide tube (7) in order to actuate the release pin (14) located there. This results in a compact overall arrangement aligned with the axis (17). The arrangement of the actuating end face (16a) in the middle of the table top (2) - with the selected single-column version - also has the advantage that an aesthetic picture of the table surface can be achieved. For example, the bolt (16) can be provided, at least on its upper side (16a), with a veneer that corresponds to the furner of the table top (2). Of course, it can also be adapted to other materials. Optical deposition of the surface (16a) by deliberately choosing other materials is also possible.
Der Bolzen (16) ist beim gezeigten Ausführungsbeispiel im Bereich seiner Unterseite mit einem Sicherrungsring (19) versehen, der als Anschlag wirkt und in der Stellung der Fig. 1 und 2 an der Unterseite der Buchse (8) anliegt. Dieser Anschlag kann so ausgestaltet und angeordnet werden, daß die obere Stirnseite (16a) des Bolzens (16) immer einwandfrei mit der Tischoberfläche (2a) fluchtet.In the exemplary embodiment shown, the bolt (16) is provided in the region of its underside with a locking ring (19) which acts as a stop and, in the position of FIGS. 1 and 2, bears against the underside of the bushing (8). This stop can be designed and arranged so that the upper end face (16a) of the bolt (16) is always perfectly aligned with the table surface (2a).
