Abstract

The desk has an obliquely adjustable worktop (3) which is attached in the region of its front edge to the body (2) of the desk on a swivel axle (5) extending parallel to said front edge. Situated behind the worktop (3) there is a shelf board (11). The shelf board (11) is attached to the rear edge of the worktop (3) on an attachment axle (12). Furthermore, a support device (15) for the shelf board (11) is attached, on the one hand, to the shelf board (11) and, on the other hand, to the body (2) via an axis of rotation (17 and 18 respectively) in each case. The swivel axle (5), the attachment axle (12) and the two axes (17, 18) of rotation form a joint parallelogram, the connection line between the swivel axle (5) and the attachment axle (12) and the connection line between the axes (17, 18) of rotation being of equal length and parallel. The connection line between the swivel axle (5) and the axis (18) of rotation and the connection line between the attachment axle (12) and the axis (17) of rotation are likewise of equal length and parallel. The shelf board (11) is situated in a lower horizontal position when the worktop (3) is horizontal and in a raised horizontal position when the worktop (3) is in an oblique position. <IMAGE>

Description

Die Erfindung betrifft einen Schreibtisch mit einer aus ihrer Horizontallage in eine Schräglage verstellbaren Arbeitsplatte, die im Bereich ihrer Vorderkante an einer parallel zu dieser verlaufenden Schwenkachse am Korpus des Schreibtisches angelenkt ist, und mit einem hinter der Arbeitsplatte angeordneten, sich parallel zu dieser erstreckenden und in der Horizontallage der Arbeitsplatte in deren Ebene angeordneten Ablagebrett.The invention relates to a desk with a worktop adjustable from its horizontal position into an inclined position, which is articulated in the region of its front edge on a pivot axis running parallel to this on the body of the desk, and with a arranged behind the worktop, extending parallel to it and in the horizontal position of the worktop in its level arranged shelf.

Bei derartigen Schreibtischen kann man die Lage der Arbeitsplatte an die jeweils ausgeübte Arbeit anpassen. Beispielsweise zum Schreiben oder Lesen beläßt man die Arbeitsplatte in ihrer Horizontallage, während man sie zum Ausführen einer Zeichentätigkeit in die Schräglage verschwenken kann, indem man sie im Bereich ihrer Hinterkante ergreift und nach oben vorne hochhebt. Besitzt nun der Schreibtisch zusätzlich zu der Arbeitsplatte ein hinter dieser angeordnetes Ablagebrett, das üblicherweise fest mit dem Korpus des Schreibtisches verbunden ist, so sind bei schräg gestellter Arbeitsplatte die auf dem Ablagebrett befindlichen Gegenstände von vorne her nicht sichtbar und nur auf umständliche Weise greifbar. Nit anderen Worten, bei einem solchen Schreibtisch ist zwar ein Ablagebrett vorhanden, dieses kann seine Funktion jedoch nur in der Horizontallage der Arbeitsplatte voll erfüllen.With such desks, the position of the worktop can be adapted to the work performed. For example, for writing or reading, the worktop is left in its horizontal position, while it can be swiveled into an inclined position to carry out a drawing activity by gripping it in the area of its rear edge and lifting it upwards at the front. If the desk now has, in addition to the worktop, a shelf arranged behind it, which is usually firmly attached to the body of the desk, the objects on the shelf are not visible from the front when the worktop is inclined and can only be gripped in a cumbersome manner. In other words, with such a desk there is a storage board, but this can only fulfill its function in the horizontal position of the worktop.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, einen Schreibtisch der eingangs genannten Art zu schaffen, bei der das Ablagebrett in jeder Lage der Arbeitsplatte seine Funktion voll erfüllt, so daß auf ihm abgelegte Gegenstände von vorne her sichtbar und mühelos greifbar sind. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Ablagebrett an der Hinterkante der Arbeitsplatte an einer Anlenkachse angelenkt ist und daß außerdem mindestens eine Stützeinrichtung für das Ablagebrett einerseits an diesem und anderarseits am Korpus an einer ablagenbrettseitigen bzw. korpusseitigen Drehachse angelenkt ist, derart, daß die Schwenkachse der Arbeitsplatte, die Anlenkachse des Ablagebrettes, die ablagenbrettseitige Drehachse der Stützeinrichtung und die korpusseitige Drehachse der Stützeinrichtung ein Gelenkparallelogramm bilden, wobei die Verbindungslinie zwischen der Schwenkachse der Arbeitsplatte und der Anlenkachse des Ablageorettes sowie die Verbindungslinie zwischen den beiden Drehachsen der Stützeinrichtung gleich lang sind und parallel zueinander verlaufen, ebenso wie die Verbindungslinie zwischen der Schwenkachse der Arbeitsplatte und der korpusseitigen Drehachse der Stützeinrichtung sowie die Verbindungslinie zwischen der Anlenkachse des Ablagebrettes und der äblagenbrettseitigen Drehachse der Stützeinrichtung gleich lang sind und parallel zueinander verlaufen, so daß das Ablagebrett in der Schrägstellung der Arbeitsplatte eine hochgehobene Horizontallage einnimmt.The present invention is therefore based on the object to provide a desk of the type mentioned, in which the storage board fully fulfills its function in any position of the worktop, so that objects placed on it are visible and easily accessible from the front. This object is achieved in that the storage board on the rear edge of the worktop is articulated on a hinge axis and that in addition at least one support device for the storage board is articulated on the one hand on this and on the other side of the body on a storage board-side or cabinet-side axis of rotation, such that the pivot axis of the worktop, the articulation axis of the storage board, the storage board-side rotation axis the support device and the body-side axis of rotation of the support device form an articulated parallelogram, the connecting line between the pivot axis of the worktop and the articulation axis of the shelf or the connecting line between the two axes of rotation of the support device being of equal length and parallel to one another, as well as the connecting line between the pivot axis of the Worktop and the body-side axis of rotation of the support device and the connecting line between the articulation axis of the storage board and the shelf board side axis of rotation of the support device are of equal length and par allel to each other, so that the storage board assumes a raised horizontal position in the inclined position of the worktop.

Gemäß weiterer Erfindung sind die vier Achsen des Gelenkparallelogramms bei sich in ihrer Horizontallage befind- > licher Schreibplatte in einer einzigen horizontalen Ebene angeordnet.According to a further invention, the four axes of the articulated parallelogram are in a horizontal plane when they are in their horizontal position arranged.

Ferner kann die Stützeinrichtung aus mindestens einem starren, sich rechtwinklig zur Arbeitsplattenvorderkante erstreckenden Stützstab bestehen, der bei nur einem Stützstab in der Mittelebene des Schreibtisches verlaufen kann.Furthermore, the support device can consist of at least one rigid support rod which extends at right angles to the front edge of the worktop and which can run in the central plane of the desk with only one support rod.

Auferdem ist es zweckmäßig, daß die Stützeinrichtung einerseits an der Unterseite des Ablagebrettes mit nach hinten gerichtetem horizontalem Abstand zur Anlenkachse des Ablagebrettes und andererseits unterhalb der Arbeitsplatte mit nach hinten gerichtetem horizontalem Abstand zur Schwenkachse der Arbeitsplatte am Korpus angelenkt ist.In addition, it is expedient that the support device is articulated on the body on the one hand on the underside of the storage board with a rearward horizontal distance to the articulation axis of the storage board and on the other hand below the work surface with a rearward horizontal distance to the pivot axis of the work surface.

Bei dem erfindungsgemäßen Schreibtisch wird also das Ablagebrett beim Hochschwenken der Arbeitsplatte nach oben vorne hin mitgenommen, da das Ablagebrett ja mit der Hinterkante der Arbeitsplatte fest verbunden ist. Infolge der gelenkigen Verbindung zwischen der Arbeitsplatte und dem Ablagebrett sowie wegen der mindestens einen Stützeinrichtung und des vorhandenen Gelenkparallelogramms verändert dabei das Ablagebrett seine Horizontallage nicht, d.h. das Ablagebrett bildet in jeder Schräglage der Arbeitsplatte sozusagen einen horizontal verlaufenden oberen Fortsatz der Arbeitsplatte. Somit sind die auf dem Ablagebrett abgelegten Gegenstände stets von vorne her zugänglich.In the desk according to the invention, the storage board is therefore taken upwards when the worktop is swung upwards, since the storage board is firmly connected to the rear edge of the worktop. As a result of the articulated connection between the worktop and the storage board and because of the at least one support device and the existing articulated parallelogram, the storage board does not change its horizontal position, that is to say the storage board forms a horizontally extending top extension of the work surface in every inclined position of the work surface. So they are on the shelf items stored on the board are always accessible from the front.

Ein Ausführungsbeispiel der Erfindung wird nun anhand der Zeichnung beschrieben. Es zeigen:

  • Fig. 1 die Seitenansicht eines Schreibtisches mit schräg gestellter Arbeitsplatte,
  • Fig. 2 die Seitenansicht einer Einzelheit des Schreibtisches gemäß Fig. 1 bei horizontaler Arbeitsplatte und
  • Fig. 3 die Draufsicht des Schreibtisches nach Fig. 1 bei horizontaler Arbeitsplatte in etwas verkleinertem Maßstab.
An embodiment of the invention will now be described with reference to the drawing. Show it:
  • 1 is a side view of a desk with an inclined worktop,
  • Fig. 2 is a side view of a detail of the desk of FIG. 1 with a horizontal worktop and
  • Fig. 3 is a plan view of the desk of Fig. 1 with the horizontal worktop on a slightly reduced scale.

Der in der Zeichnung dargestellte Schreibtisch besitzt einen an Stützbeinen 1 aufgehängten Korpus 2. Der Korpus 2 wird nach oben hin von einer Arbeitsplatte 3 abgeschlossen, die im Bereich ihrer Vorderkante 4 an einer parallel zu der Vorderkante 4 verlaufenden Schwenkachse 5 am Korpus 2 mit Hilfe einer Scharnierschiene 6 angelenkt ist, die über die gesamte Länge der Arbeitsplatte durchgeht. Die Scharnierschiene 6 ist also einerseits mit ihrem einen Schenkel 7 am Eorpus 2 und mit ihrem anderen Schenkel 8 an der Arbeitsplatte 3 befestigt. Die Arbeitsplatte 3 ist somit zwischen einer Horizontallage (Fig. 2) und einer Schräglage (Fig. 1) verschwenkbar, wobei sie in der gewünschten Schräglage mit Hilfe einer z.B. aus einem Rastgestänge bestehenden Feststelleinrichtung 9 feststellbar ist, die nur gestrichelt angedeutet ist, da sie im Zusammenhang mit der vorliegenden Erfindung beliebiger Natur sein kann. Ebenfalls gestrichelt angedeutet ist eine z.B. aus einer Gasfeder bestehende Dämpfeinrichtung 10.The desk shown in the drawing has a body 2 suspended from supporting legs 1. The body 2 is closed at the top by a worktop 3, which in the area of its front edge 4 on a pivot axis 5 running parallel to the front edge 4 on the body 2 with the aid of a Hinge rail 6 is articulated, which runs over the entire length of the worktop. The hinge rail 6 is therefore on the one hand with its one leg 7 attached to the Eorpus 2 and with its other leg 8 to the worktop 3. The worktop 3 can thus be pivoted between a horizontal position (FIG. 2) and an inclined position (FIG. 1), it being able to be determined in the desired inclined position with the aid of a locking device 9, for example consisting of a latching linkage, which is only indicated by dashed lines since it can be of any nature in connection with the present invention. A damping device 10, for example consisting of a gas spring, is also indicated by dashed lines.

Von der Arbeitsseite des Scheibtisches her gesehen hinter der Arbeitsplatte 3 erstreckt sich parallel zu dieser ein Ablagebrett 11, das ebenfalls über die gesamte Schreibtischlänge durchgehen kann. Die Hinterkante der Arbeitsplatte 3 und die Vorderkante des Ablagebrettes 11 liegen einander unmittelbar gegenüber, wobei das Ablagebrett 11 an der Hinterkante der Arbeitsplatte 3 an einer Anlenkachse 12 angelenkt ist. Diese Anlenkachse 12 kann von einzelnen gleichmäßig verteilten Winkelscharnieren 13 gebildet werden (Fig. 3).Seen from the working side of the writing table, behind the worktop 3 extends parallel to it a storage board 11 which can also extend over the entire length of the desk. The rear edge of the work surface 3 and the front edge of the storage board 11 lie directly opposite one another, the storage board 11 being articulated on the rear edge of the work surface 3 on a pivot axis 12. This articulation axis 12 can be formed by individual uniformly distributed angle hinges 13 (FIG. 3).

Am Ablagebrett 11 ist außerdem über einen mit dem Ablagebrett 11 fest verbundenen Anlenkschuh 14 eine Stützeinrichtung 15 angelenkt, die andererseits über einen Anlenkwinkel 16 an der mit dem Korpus 2 fest verbundenen Scharnierschiene 6 angelenkt ist. Die beiden Anlenkstellen der Stützeinrichtung 15 werden von einer ablagenbrettseitigen Drehachse 17 bzw. von einer korpusseitigen Drehachse 18 gebildet.A support device 15 is also articulated on the storage board 11 via a link shoe 14 which is firmly connected to the storage board 11 and which is on the other hand connected via a link angle 16 is articulated to the hinge rail 6 which is firmly connected to the body 2. The two articulation points of the support device 15 are formed by an axis of rotation 17 on the storage board side or by an axis of rotation 18 on the body side.

Die Verbindungslinie zwischen der Schwenkachse 5 der Arbeitsplatte 3 und der Anlenkachse 12 des Ablagebretts 11 sowie die Verbindungslinie zwischen den beiden Drehachsen 17, 18 der Stützeinrichtung 15 sind gleich lang und verlaufen parallel zueinander. Gleiches gilt bezüglich der Verbindungslinie zwischen der Schwenkachse 5 der Arbeitsplatte 3 und der korpusseitigen Drehachse 18 der Stützeinrichtung 15 sowie der Verbindungslinie zwischen der Anlenkachse 12 des Ablagebrettes 11 und der ablagebrettseitigen Drehachse 17 der Stützeinrichtung 15. Die Schwenkachse 5 der Arbeitsplatte 3, die Anlenkachse 12 des Ablagebretts 11, die ablagenbrettseitige Drehachse 17 der Stützeinrichtung 15 und die korpusseitige Drehachse 18 der Stützeinrichtung 15 bilden somit ein Gelenkparallelogramm. Bei diesem Gelenkparallebgramm ist, was sich aus dem Bisherigen von selbst ergibt, die ablagenbrettseitige Drehachse 17 und die korpusseitige Drehachse 18 der Stützeinrichtung 15 mit nach hinten gerichtetem horizontalem Abstand zur Anlenkachse 12 des Ablagebrettes 11 bzw. mit nach hinten gerichtetem horizontalem Abstand zur Schwenkachse 5 der Arbeitsplatte 3 angeordnet.The connecting line between the pivot axis 5 of the worktop 3 and the articulation axis 12 of the storage board 11 and the connecting line between the two axes of rotation 17, 18 of the support device 15 are of the same length and run parallel to one another. The same applies to the connecting line between the pivot axis 5 of the worktop 3 and the body-side axis of rotation 18 of the support device 15 and the connecting line between the articulation axis 12 of the storage board 11 and the storage board-side axis of rotation 17 of the support device 15. The pivot axis 5 of the worktop 3, the articulation axis 12 of the Storage boards 11, the storage board-side axis of rotation 17 of the support device 15 and the body-side rotation axis 18 of the support device 15 thus form an articulated parallelogram. In this joint parallel program, which results from the previous of itself, the storage board-side axis of rotation 17 and the body-side axis of rotation 18 of the support device 15 with a rearward horizontal distance to the articulation axis 12 of the storage board 11 or with back ge aligned horizontal distance from the pivot axis 5 of the worktop 3 is arranged.

Das vor allem aus Fig. 1 deutlich sichtbare Gelenkparallelogramm bewirkt nun, daß das Ablagebrett 1 unabhängig von der Lage der Arbeitsplatte 3 stets horizontal gerichtet ist. Befindet sich also die Arbeitsplatte 3 in ihrer Horizontallage (Fig. 2), so ist das Ablagebrett 11 hinter der Arbeitsplatte 3 in der gleichen Ebene angeordnet und bildet mit dieser eine gemeinsame Schreibtischfläche. Schwenkt man die Arbeitsplatte 3 in Richtung des Pfeiles 19 um die Schwenkachse 5 hoch, beschreibt die Anlenkachse 12 des Ablagebrettes 11 eine Kreisbahn um die Schwenkachse 5. Gleichzeitig vollführt die ablagenbrettseitige Drehachse 17 eine entsprechende, nach hinten versetzte Kreisbahn um die korpusseitige Drehachse der Stützeinrichtung 15, wobei die beiden Kreismittelpunkte um den Abstand zwischen der Schwenkachse 5 und der korpusseitigen Drehachse 18 zueinander versetzt sind. Das Ablagebrett 11 wird also beim Hochschwenken der Arbeitsplatte 3 nach oben vorne hin mitgenommen, wobei die insgesamt vorhandenen vier Gelenkachsen bewirken, daß das Ablagebrett 11 seine horizontale Lage beibehält. In jeder Lage der Arbeitsplatte 3 steht das Ablagebrett 11 von der Hinterkante der Arbeitsplatte nach hinten hin horizontal vor.The articulated parallelogram, which is clearly visible above all from FIG. 1, now causes the storage board 1 to be directed horizontally regardless of the position of the worktop 3. If the worktop 3 is in its horizontal position (FIG. 2), the storage board 11 is arranged behind the worktop 3 in the same plane and forms a common desk surface with it. If the worktop 3 is pivoted in the direction of arrow 19 around the pivot axis 5, the articulation axis 12 of the storage board 11 describes a circular path around the pivot axis 5 , the two centers of the circle being offset from one another by the distance between the pivot axis 5 and the body-side axis of rotation 18. The storage board 11 is thus taken upwards when the worktop 3 is swiveled upwards, the four joint axes present in total causing the storage board 11 to maintain its horizontal position. In each position of the worktop 3, the storage board 11 projects horizontally from the rear edge of the worktop towards the rear.

Aus Fig. 2 ist außerdem ersichtlich, daß die vier Achsen 5, 12, 17, 18, des Gelenkparallelogramms bei sich in ihrer Horizontallage befindlicher Arbeitsplatte 3 in einer einzigen horizontalen Ebene angeordnet sind, d.h. in Seitenansicht gesehen liegen diese vier Achsen auf einer Linie.From Fig. 2 it can also be seen that the four axes 5, 12, 17, 18 of the articulated parallelogram are arranged in a horizontal plane when the worktop 3 is in their horizontal position, i.e. seen in side view, these four axes lie on one line.

Bei dem in der Zeichnung dargestellten Ausführungsbeispiel besteht die Stützeinrichtung 15 aus einem starren, sich rechtwinklig zur Arbeitsplattenvorderkante 4 erstreckenden Stützstab, der in der Mittelebene des Schreibtischs verläuft (Fig. 3). Selbstverständlich können auch mehrere derartige Stützstäbe vorhanden sein, die in Längsrichtung des Schreibtisches gesehen verteilt sind. Des weiteren versteht sich, daß die Stützeinrichtung 15 einerseits über den Anlenkschuh 14 an der Unterseite des Ablagebrettes 11 und andererseits unterhalb der Schreibplatte 3 am Korpus angelenkt ist.In the embodiment shown in the drawing, the support device 15 consists of a rigid support rod, which extends at right angles to the worktop front edge 4 and runs in the central plane of the desk (FIG. 3). Of course, there can also be a plurality of such support rods, which are distributed as seen in the longitudinal direction of the desk. Furthermore, it goes without saying that the support device 15 is articulated on the one hand via the articulation shoe 14 on the underside of the storage board 11 and on the other hand below the writing plate 3 on the body.

Denkbar ist allerdings auch, daß die Stützeinrichtung seitlich außen am Ablagebrett 11 bzw. am Korpus befestigt ist. In diesem Falle wäre die Stützeinrichtung jedoch von vorne und der Seite her gesehen sichtbar, selbst wenn die Arbeitsplatte ihre Horizontallage einnimmt. Demgegenüber ist beim dargestellten Ausführungsbeispiel der die Stützeinrichtung bildende Stützstab bei horizontaler Arbeitsplatte in den Schreibtisch versenkt.However, it is also conceivable that the support device is attached laterally on the outside on the storage board 11 or on the body. In this case, however, the support device would be visible from the front and the side, even if the worktop is in its horizontal position. In contrast, in the illustrated embodiment, the support rod forming the support device is for horizontal work plate sunk into the desk.

Der dargestellte Schreibtisch besitzt eine einzige als Parallelogramm ausgebildete Stützeinrichtung. Es ist jedoch selbstverständlich auch möglich, je nach der Länge der Arbeitsplatte bzw. des Ablagebrettes mehrere solche Stützeinrichtungen, z.B. zwei oder drei, vorzusehen.The desk shown has a single support device designed as a parallelogram. However, it is of course also possible, depending on the length of the worktop or the storage board, of several such support devices, e.g. two or three to provide.
