HEIGHT-ADJUSTABLE MULTI-FUNCTION DESK

Abstract

A workstation system (1) has an office desk with a seated work area and a standing working area. A support frame (10) is height-adjustable in the vertical axis H for synchronously adjusting the height of two desktops (T1, T2) attached to the frame at different work levels (A1, A2) to form respective seated and standing working areas. The desktops (T1, T2) are attached to the support frame at a fixed distance to each other in the vertical axis H. The upper desktop (T2) is arranged above the working level (A1) of the lower desktop (T1) in the vertical axis.

23. The workstation system according to claim 13, wherein the lower and upper desktops are connected to each other via a joint, such that the upper desktop can be rotated relative to the lower desktop about a rotary axis while maintaining the working levels.

24. A method for setting up and adjusting the height of a desktop of a workstation system according to claim 13, that is equipped with a control system for the automatic or user-activated synchronous adjustment of the height of the desktops of the workstation, when switching from a seated to a standing position, and/or vice versa, for an individual user comprising the steps of: Entering user-specific physical data, such as height, leg length or torso length of a user; Setting a first height position of the lower desktop for the user, that corresponds to a desired height for working in the seated position; Determining whether the height of the upper desktop at the height position of the lower desktop matches the corresponding body measurements for a reference user stored in the system and, if a deviation is detected, store a height correction value in the range between +/−7 cm, such that, in case of an actual or detected change of this user from the seated position to the standing position, the controller performs, either automatically or user-prompted, a height adjustment according to the height correction value, and a corresponding correction is performed in the opposite direction when the user returns from the standing position to a seated position.

DETAILED DESCRIPTION

[0052] In the following, the disclosure is explained in more detail with reference to FIGS. 1 to 8. Identical reference numbers in the drawings indicate identical functional and/or structural characteristics.

[0053] FIGS. 1, 6 and 8 show three exemplary embodiments of workstation systems according to the disclosure, namely office desks 1. The desks 1 have respective support frames 10 including a left desk frame 10a and a right desk frame 10b. Each has a height-adjustable column 12, at the top of which a bracket 13 is provided for the support of the lower desktop T1.

[0054] The desks 1 define a seated work area in these embodiments essentially in the right half of desk 1 and a standing work area essentially in the left half of the desk 1. An expanded user area for the seated position, and thus the seating area, is formed below the upper desktop T2.

[0055] The support frame 10, height-adjustable along the vertical axis H, is used for the synchronous height adjustment of the two desktops T1, T2 attached to the support frame 10 at different working levels A1, A2.

[0056] The desktops T1, T2 are mounted to the support frame at a fixed distance of 33 cm in the vertical axis H to each other. The upper desktop T2 is arranged above the working level A1 of the lower desktop T1 as seen in the vertical axis. In the exemplary embodiment of FIGS. 1 to 5, the upper and lower desktops T1, T2 are formed of one piece.

[0057] As shown in FIGS. 2, 7 and 8, the lower and upper desktops T1, T2 are connected to each other via a vertical desk section T3.

[0058] The top views in FIGS. 2 and 8 show that the upper desktop T2 has a width B2, that corresponds to about 50% of the width B1 of the lower desktop T1. Furthermore, the drawings show that the orientation of the front edge V2 of the upper desktop T2, which edge is directed toward a user, forms an angle of about 20° to the orientation of the front edge V1 of the lower desktop T1, that is, an angle of 160° between the edges.

[0059] The drawings of the different embodiments also show that a vertical support strut 30 extends between the lower desktop T1 and the upper desktop T2.

[0060] In the lower view of FIG. 5, the upper desktop is not connected to the lower desktop as one piece. Here, the upper desktop can be rotated via a joint, namely a rotary column D, about the column axis by a desired rotation angle. Thus, the user can adjust the angle and position of the upper desktop according to his/her personal needs. In this context, one option is to attach a rail system S to the lower desktop, which engages with a leg S protruding downward from the upper desktop via a linkage on the lower end of the leg (e.g., a set of rollers), such that the upper desktop is supported during the rotational movement. The leg can be attached to the desktop at its upper end. See FIG. 10.

[0061] It is particularly advantageous if a guide rail F is mounted flush in the desktop, such that no inconvenient edges protrude from the desktop.

[0062] Another alternative solution is to provide a leg that extends along the side edge of the desk or at another suitable location that is least intrusive to the user from the lower desktop upward to the bottom of the upper desktop. It is advantageous if there is a roller bearing at the upper end of said leg, on which the upper desktop is supported, preferably a roller bearing that is arranged in a rotatable manner. If the upper desktop is then rotated into a position desired by the user, the desktop moves on top of the support leg and is thus supported.

[0063] The embodiments of the disclosure are not limited to the aforementioned preferred embodiments. Rather, a number of variants are conceivable, that make use of the solution shown here even if they arrive at fundamentally different versions.
