Description
Motor-adjustable work table

The invention relates to a motor-adjustable work table according to the preamble of claim 1.

Work tables, CAD work surfaces and the like are often motorically adjustable in height, inclination, etc. An actuation switch, which is located on the worktop of the work table, is used to operate the motorized adjustment.

It is known to mount the operating switch permanently on the underside of the worktop. This has the disadvantage that the operating switch is difficult to access and is not visible for operation.

It is also known to attach the operating switch to the edge of the worktop facing the user, so that it protrudes beyond the worktop. With this arrangement, there is a risk of damage to the operating switch. In particular, with this arrangement, the operating switch is often damaged by the armrests of a chair.

It is also known to embed the operating switch in the worktop so that it is clearly visible on the top of the worktop and can be operated easily. However, this requires extensive processing of the worktop and the connecting cable of the operating switch must be led through the worktop.

The invention is based on the object of designing a motor-adjustable work table with an operating switch in such a way that the operating switch is easily accessible to the user and protected against damage.

This object is achieved according to the invention by the features of claim 1. Advantageous embodiments of the invention are specified in the subclaims.

The main idea of the invention is to attach the operating switch to the underside of the worktop so that it can be pivoted. The operating switch is mounted eccentrically in such a way that it can be pivoted between an operating position and a parking position. In the operating position, the operating switch protrudes over the edge of the worktop on the user side so that it is clearly visible to the user and easy to operate. In the parking position, the operating switch is pivoted under the worktop so that it is almost invisible and, in particular, is protected against damage and does not hinder the person working at the work table.

Due to the eccentric bearing of the actuating switch, a relatively small swivel angle is sufficient to swivel the actuating switch between the actuating position and the parking position. The design of the actuating switch and the swivel arm is preferably selected so that the actuating switch is arranged in the actuating position with its longitudinal extension parallel to the edge of the worktop. This not only results in good accessibility and a space-saving arrangement, but also an attractive design.

Due to its pivoting bearing, the actuating switch is not only protected against damage in its parked position. Even when the actuating switch is in its actuating position in front of the worktop, the pivoting ability provides protection against damage. The actuating switch can avoid impacts, e.g. from the user, a work chair or the like, and swing under the worktop. The eccentric bearing has the additional advantage that the evasive swivel movement

of the actuating switch regardless of the direction in which an impact acts on the actuating switch.

In the following, the invention is explained in more detail using an embodiment shown in the drawing.
The only figure shows a top view of the worktop
The actuating switch is shown in solid lines in its actuating position and in dashed lines in its parking position.

In the drawing, a worktop 10 of a work table,
a CAD work surface or the like is indicated by its dashed edge on the user side.

On the underside of the worktop 10 there is a swivel bearing
12 spaced from the edge of the worktop 10. The pivot axis of the pivot bearing 12 runs essentially
perpendicular to the plane of the worktop 10.

A swivel arm 14 is pivotably mounted on the swivel bearing 12. The swivel arm 14 carries at its end
12 opposite free end an actuating switch 16. The
The operating switch 16 is accommodated in a switch housing 18 and is accessible from the upper side facing the worktop 10.

By means of the operating switch 16, the work table can be
can be adjusted by motor in a known manner. For example,
The height of the worktop 10 and/or its angle of inclination can be adjusted. For this purpose, the operating switch
16 via a connecting cable (not shown) with
the actuator or actuators of the adjustment mechanism
In the illustrated embodiment, the
Operating switch 16 a button 20 for switching on
of the servomotor, additional memory keys 22 for predeterminable

stored adjustment positions, a display 24 for the up and down movement of the adjustment drive and a digital height display 26.

The swivel arm 14 with the actuation switch 16 can be swiveled between an actuation position shown in the drawing - in solid line and a parking position shown in dashed lines in the drawing. These two positions are preferably defined mechanically. For this purpose, for example, stops can be attached to the underside of the worktop 10, which limit the swivel angle of the swivel arm 14 in the actuation position and the parking position as end positions. A corresponding limitation of the swivel angle can also be provided in the swivel bearing 12. Furthermore, it is possible to define the actuation position and the parking position by means of positive or non-positive detents.

As can be seen from the drawing, the swivel arm 14 is angled. In a first section arranged on the swivel bearing 12, the swivel arm 14 runs radially to the axis of rotation of the swivel bearing 12. This is followed by a section angled towards the user edge of the worktop 10, at the end of which the actuation switch 16 is arranged so that it runs essentially parallel to the section on the swivel bearing side. Accordingly, in the actuation position, the section of the swivel arm 14 on the swivel bearing side runs parallel to the user edge of the worktop 10. The actuation switch 16 is located 0 in front of the edge of the worktop 10 and runs parallel to this edge. The actuation switch 16 with its switch housing 18 therefore only protrudes slightly above the worktop 10 and its operating surface is clearly visible and easily accessible. It can also be seen from the drawing that 5 pressure or impact forces acting against the actuating switch 16 or the switch housing 18 exert a pivoting moment on the pivot arm 10, by means of which the pivot arm 14

with the operating switch 16 under the worktop 10 into the parking position. Due to the eccentric design of the swivel arm 14 with respect to the swivel bearing, pressure and impact forces lead to a swiveling of the
Swivel arm 14 under the worktop 10 regardless of the direction in which these forces act on the actuating switch 16 or the switch housing 18. Such forces can act perpendicular to the edge of the worktop 10 or from the left or from the right on the actuating switch in the drawing.
16 take effect.

In the actuating position of the actuating switch 16,
This can be operated comfortably and clearly. Once the adjustment process is complete, the operating switch

16 is pivoted into the parking position under the worktop 10 by applying light pressure against its front edge. In the same
In this way, the actuating switch 16 is pivoted under the worktop 10 if an unintentional impact or pressure is applied to the actuating switch 16. In the parking position, the actuating switch 16 is located completely below the worktop 10 behind its user-side edge, so that the actuating switch 16 is protected against damage and the user working on the worktop 10
not obstructed. To adjust the work table 10,

the actuating switch 16 can be swung back into the actuating position with a simple movement of the hand.

In the drawing, the swivel arm 14 with the actuating switch 16 protrudes from the swivel bearing 12 to the right. In this version, the actuating switch 16 is located to the right of the

User mounted on the worktop 10 and operated with the right hand. For mounting to the left of the user and for operation with the left hand, the swivel arm 14 with the actuating switch 16 is a mirror image of the

The design shown in the drawing is as follows.
