Description

Die Erfindung bezieht sich auf einen Arbeitstisch mit einem der Höhe nach verstellbaren, eine Tischplatte aufnehmenden Gestell, mit wenigstens einem elektrischen Motor zur Verstellung des Gestells und mit einer von Hand betätigbaren Schalteinrichtung mit zwei Schaltfunktionen zum gegensinnigen Ansteuern einer Steuereinrichtung für den Motor.The invention relates to a work table with a height adjustable, a table top receiving frame, with at least one electrical Motor for adjusting the frame and with a manually operable Switching device with two switching functions for controlling one in opposite directions Control device for the engine.

Arbeitstische, die ein der Höhe nach verstellbares Gestell aufweisen und mittels wenigstens eines elektrischen Motors zur Sicherstellung vorteilhafter ergonomischer Verhältnisse in unterschiedliche Arbeitsstellungen bewegt werden können, weisen im allgemeinen zur Ansteuerung der für den Motor vorgesehenen Steuereinrichtung eine von Hand betätigbare Schalteinrichtungen mit zwei Tastschaltern auf, die die Steuereinrichtung für den Motor einerseits im Sinne eines Hebens und anderseits im Senksinn der Tischplatte ansteuern. Diese Tastschalter sind üblicherweise unmittelbar nebeneinander angeordnet, was vor allem dann zu Handhabungsschwierigkeiten führt, wenn die Schalteinrichtung außerhalb des Arbeitsbereiches, beispielsweise unterhalb der Tischplatte, angeordnet wird, so daß die Tastschalter für die voneinander getrennten Schaltfunktionen der Auf- und Abbewegung kaum eingesehen werden können. In diesem Fall ist mit Fehlbedienungen zu rechnen.Work tables that have a height-adjustable frame and by means of at least one electric motor to ensure advantageous ergonomic Conditions can be moved to different working positions, generally have to control the intended for the engine Control device a manually operated switching devices with two pushbuttons on the one hand, the control device for the engine in the sense of a Activate lifting and on the other hand in the descending direction of the table top. This push button are usually arranged directly next to each other, which is especially true Handling difficulties leads when the switching device outside the Working area, for example below the table top, is arranged so that the push buttons for the separate switching functions of the up and Movement can hardly be seen. In this case, with Incorrect operations to be expected.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Arbeitstisch der eingangs genannten Art so auszugestalten, daß eine vorteilhafte, sichere Handbedienung möglich wird, selbst wenn die Schalteinrichtung außerhalb des üblichen Sichtbereiches eines Tischbenützers angeordnet ist. The invention is therefore based on the object of a work table type mentioned so that an advantageous, safe manual operation becomes possible even if the switching device is outside the usual Viewing area of a table user is arranged.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die Schalteinrichtung einen auf der Unterseite der Tischplatte in deren Randbereich angeordneten Folienschalter zur Beaufschlagung der Steuereinrichtung im Sinne eines Hebens der Tischplatte und ein durch einen Druck auf die Oberseite der Tischplatte betätigbares Schaltglied zur gegensinnigen Ansteuerung des Motors aufweist.The invention solves the problem in that the switching device a membrane switch arranged on the underside of the table top in its edge area to act upon the control device in the sense of lifting the Table top and one that can be actuated by pressing the top of the table top Has switching element for the opposite control of the motor.

Durch das Vorsehen eines Folienschalters zur Beaufschlagung der Steuereinrichtung im Sinne eines Hebens auf der Unterseite der Tischplatte wird die dem Heben der Tischplatte entsprechende Handbewegung für die Motorsteuerung ausgenützt, ohne jedoch die für das Heben der Tischplatte erforderliche Kraft von Hand aus aufwenden zu müssen. In ähnlicher Weise wird durch das Vorsehen eines Schaltgliedes, das durch einen Druck auf die Oberseite der Tischplatte betätigt wird, die natürliche Handbewegung zum Senken der Tischplatte für die Steuerung dieser Tischplattenbewegung genützt, was ergonomisch vorteilhafte Handhabungsbedingungen schafft, die eine Fehlbedienung praktisch ausschließen.By providing a membrane switch to act on the control device in the sense of lifting on the underside of the table top hand movement corresponding to the lifting of the table top for the motor control exploited, but without the force required for lifting the table top To have to spend hand out. Similarly, by providing a switching element, which is actuated by pressing on the top of the table top the natural hand movement to lower the table top for control this table top movement benefits what ergonomically advantageous handling conditions creates, which practically exclude incorrect operation.

Die Tischplatte selbst kann als Schaltglied für die Abwärtsbewegung genützt werden, wenn die Steuereinrichtung an einen Geber für die Motorbelastung angeschlossen ist und der Motor eine von der Steuereinrichtung in Abhängigkeit von einer Änderung der Motorbelastung ansteuerbare, über den Folienschalter für das Heben der Tischplatte freischaltbare Umpoleinrichtung aufweist. Wird nämlich von Hand aus auf die Tischplatte ein Druck von oben ausgeübt, so ändert dieser Druck die Motorbelastung, was bei einer entsprechend feinfühligen Überwachung der Motorbelastung zur Ausgabe eines Steuersignals genützt werden kann, mit dessen Hilfe die Umpoleinrichtung des Motors für die Abwärtsbewegung der Tischplatte angesteuert werden kann. Voraussetzung hiefür ist, daß der Motor zunächst über den Folienschalter auf der Tischplattenunterseite eingeschaltet wird. Mit der Betätigung des Folienschalters wird die Umpoleinrichtung für eine vorgegebene Zeitspanne freigeschaltet. Erfolgt keine Druckbelastung der Tischplatte von oben, so wird die Tischplatte angehoben, solange der Folienschalter, der einen Tastschalter bildet, gedrückt wird. Nur wenn innerhalb der vorgegebenen Zeitspanne nach dem Einschalten des Motors ein entsprechender Steuerdruck auf die als Schaltglied wirksame Tischplatte ausgeübt wird, wird der Motor umgepolt und der Tisch gesenkt, wobei vorteilhafterweise die Geschwindigkeit von einem Schleichgang auf die vorgesehene Stellgeschwindigkeit erhöht wird, und zwar sowohl für das Senken als auch für das Heben des Arbeitstisches.The table top itself can be used as a switching element for the downward movement when the control device is connected to an encoder for the engine load is connected and the motor is dependent on the control device controlled by a change in the motor load, via the membrane switch for the lifting of the table top has unlockable polarity reversal device. Because namely If pressure is exerted on the table top by hand, this changes Pressure the engine load, what with a correspondingly sensitive monitoring the engine load can be used to output a control signal with whose help is the motor's pole reverser for the downward movement of the Table top can be controlled. The prerequisite for this is that the engine is first switched on using the membrane switch on the underside of the table top. With the actuation of the membrane switch, the polarity reversal device becomes a predetermined one Time period unlocked. There is no pressure load on the table top from above, the table top is raised as long as the membrane switch, the forms a push button, is pressed. Only if within the given Time after switching on the engine a corresponding control pressure the table top is used as a switching element, the motor is reversed and the table lowered, advantageously the speed of one Creep speed is increased to the intended positioning speed, namely for both lowering and lifting the work table.

Die Tischplatte selbst als Schaltglied zu verwenden, bringt den Vorteil mit sich, daß die Oberseite der Tischplatte vollständig als Arbeitsbereich zur Verfügung steht. Wird auf diesen Vorteil verzichtet, so kann das Schaltglied aus einem zusätzlichen, auf der Oberseite der Tischplatte angeordneten, dem Folienschalter auf der Tischunterseite gegenüberliegenden Folienschalter bestehen, über den die Steuereinrichtung für den Motor im Sinne eines Senkens der Tischplatte beaufschlagt wird. Diese Ausführungsform erlaubt den Einsatz herkömmlicher Steuereinrichtungen, weil die beiden Folienschalter auf der Ober- und der Unterseite der Tischplatte lediglich herkömmliche Tastschalter ersetzen.Using the table top itself as a switching element has the advantage yourself that the top of the table top is fully available as a work area stands. If this advantage is dispensed with, the switching element can consist of one additional, located on the top of the table top, the membrane switch on the underside of the table opposite the film switch, via which the Control device for the motor in the sense of lowering the table top becomes. This embodiment allows the use of conventional control devices, because the two membrane switches on the top and bottom of the Only replace the table top with conventional push buttons.

Um einfache Montageverhältnisse zu erreichen, können die beiden Folienschalter durch einen Steg zu einer den Rand der Tischplatte beidseitig umfassenden Baueinheit verbunden werden, die beispielsweise auf die Tischplatte aufgeklebt wird.To achieve simple installation conditions, the two membrane switches through a web to one that surrounds the edge of the table top on both sides Be connected unit, for example, glued to the table top becomes.

Der Arbeitstisch gemäß den dargestellten Ausführungsbeispielen weist ein eine Tischplatte 1 tragendes Gestell 2 auf, das Teleskopbeine 3 zur Aufnahme der Tischplatte 1 bildet. Diese Teleskopbeine 3 werden durch je einen elektrischen Motor 4 angetrieben, der beispielsweise über ein Ritzel 5 eine Zahnstange 6 der Teleskopbeine 3 verschiebt. Den Motoren 4 ist eine Steuereinrichtung 7 zugeordnet, die über eine Schalteinrichtung 8 betätigt werden kann. Die Schalteinrichtung 8 weist einen auf der Unterseite der Tischplatte 1 angeordneten Folienschalter 9 auf, der die Steuereinrichtung 7 im Sinne eines Hebens der Tischplatte 1 beaufschlagt. Zur gegensinnigen Verstellung der Tischplatte 1 ist ein Schaltglied 10 vorgesehen, das durch einen Druck auf die Oberseite der Tischplatte 1 betätigt wird. lm Ausführungsbeispiel nach der Fig. 1 wird dieses Schaltglied 10 durch die Tischplatte 1 selbst gebildet. Der von Hand aus auf die Tischplatte 1 von oben ausgeübte Druck bewirkt eine Änderung der Motorbelastung, die beispielsweise über den aufgenommenen Strom erfaßt werden kann. Zu diesem Zweck ist die Steuereinrichtung 7 an einen Meßwertgeber 11 für den Motorstrom angeschlossen, so daß in einer Auswerteschaltung der Steuereinrichtung 7 eine entsprechende Belastungsänderung der Motoren 4 festgestellt und in Abhängigkeit davon eine Umpoleinrichtung 12 für die Motoren 4 angesteuert werden kann, so daß über die umgepolten Motoren 4 die Tischplatte 1 bei einem Druck von oben abgesenkt wird.The work table according to the illustrated embodiments has a a table top 1 supporting frame 2, the telescopic legs 3 for receiving the Table top 1 forms. These telescopic legs 3 are each electric Motor 4 driven, for example via a pinion 5, a rack 6 of the Telescopic legs 3 moves. A control device 7 is assigned to the motors 4, which can be actuated via a switching device 8. The switching device 8 has a film switch 9 arranged on the underside of the table top 1 on, which acts on the control device 7 in the sense of lifting the table top 1. A switching element 10 is used to adjust the tabletop 1 in the opposite direction provided, which is actuated by pressure on the top of the table top 1 becomes. 1, this switching element 10 is by the Tabletop 1 itself formed. The hand on the table top 1 from above Exerted pressure causes a change in the engine load, for example can be detected via the current consumed. For this purpose, the Control device 7 connected to a sensor 11 for the motor current, so that a corresponding in an evaluation circuit of the control device 7 Change in load of the motors 4 determined and a depending on it Umpoleinrichtung 12 can be controlled for the motors 4, so that on the reversed motors 4, the table top 1 is lowered at a pressure from above.

Es muß selbstverständlich sicher gestellt sein, daß nicht jede zusätzliche Belastung der Tischplatte 1 zu deren Absenkung führt. Aus diesem Grunde wird mit der Betätigung des Folienschalters 9 auf der Unterseite der Tischplatte 1 ein Zeitglied 13 angestoßen, über das die Umpoleinrichtung 12 für ein vorgegebenes Zeitfenster freigeschaltet wird. Wird innerhalb dieses Zeitfensters ein entsprechender Druck auf die Tischplatte 1 von oben ausgeführt, so erfolgt die Abwärtssteuerung der Tischplatte 1. Da über den Folienschalter 9 die Hebebewegung für die Tischplatte 1 eingeleitet wird, die dann gegebenenfalls in eine Senkbewegung umgekehrt wird, empfiehlt es sich, die Motoren 4 während des durch das Zeitglied 13 bestimmten Zeitfensters mit einem Schleichgang zu betreiben und erst nach Ablauf der vorgegebenen Zeitspanne die Verstellgeschwindigkeit auf das vorgesehene Maß zu erhöhen.Of course, it must be ensured that not every additional one Loading the table top 1 leads to its lowering. For this reason with the actuation of the membrane switch 9 on the underside of the table top 1 Triggered timer 13 via which the pole reversal device 12 for a predetermined Time window is unlocked. A corresponding one will appear within this time window Pressure on the table top 1 carried out from above, so the downward control takes place the table top 1. Because the membrane switch 9, the lifting movement for the Table top 1 is initiated, which then optionally in a lowering movement is reversed, it is recommended that the motors 4 during the by the timer 13 to operate with a creep speed and only after The adjustment speed to the intended time expires Increase measure.

Im Ausführungsbeispiel nach den Fig. 2 und 3 wird das Schaltglied 10 der Schalteinrichtung 8 aus einem zusätzlichen Folienschalter 14 gebildet, der durch einen Steg 15 mit dem Folienschalter 9 auf der Tischplattenunterseite zu einer Baueinheit verbunden ist, so daß sich die beiden Folienschalter 9, 14 auf der Unter- und der Oberseite der Tischplatte 1 einander gegenüberliegen und je einen Tastschalter zur Beaufschlagung der Steuereinrichtung 7 für die ihnen zugeordnete Schaltfunktion bilden. Wie sich aus dem Blockschaltbild der Fig. 3 im Zusammenhang mit Fi. 2 ergibt, wird bei einer Betätigung des Folienschalters 14 auf der Oberseite der Tischplatte 1 die Steuereinrichtung 7 mit einem Steuersignal zum Absenken der Tischplatte 1 beaufschlagt, während eine Druckbelastung des Folienschalters 9 auf der Unterseite der Tischplatte 1 ein Heben der Tischplatte 1 nach sich zieht.In the embodiment of FIGS. 2 and 3, the switching element 10 is the Switching device 8 is formed from an additional membrane switch 14, which by a web 15 with the membrane switch 9 on the underside of the table top to one Unit is connected so that the two membrane switches 9, 14 on the lower and the top of the table top 1 face each other and one each Push-button switch to act upon the control device 7 for the one assigned to it Form switching function. How in context from the block diagram of FIG. 3 with fi. 2 results, is activated when the membrane switch 14 on the Top of the table top 1, the control device 7 with a control signal Lowering of the table top 1 is applied while the membrane switch is under pressure 9 on the underside of the table top 1 after lifting the table top 1 pulls itself.
