Office furniture with a height-adjustable and / or tiltable desk top

The present invention relates to office furniture with a height-adjustable and / or tiltable desk top.

There are height-adjustable desks, in particular for schoolchildren, known as well as height-adjustable and inclination-adjustable tables, in particular Hospital tables.

These known constructions cannot be applied to office furniture with a desk top without the the resulting construction is cumbersome to adjust, expensive to manufacture and unsightly.

The present invention aims to create office furniture with a height-adjustable and / or tiltable desk top, which acts and is designed as a unit, and which can be easily adjusted in height and / or inclined without the need for special tools or without the need for auxiliary staff.

Such office furniture is characterized according to the invention characterized in that the desk top is resiliently mounted at several points so that it can move in height.

An embodiment of the subject invention is then explained using a drawing.

FIG. 8 shows a detail from the upper part of the office furniture according to section line VIII - VIII of FIG. 5, with a pretensioning device and the desk plate in a pretensioned position,

FIG. 9 shows the detail from the illustration according to FIG. 8, in the direction of arrow A in FIG. 8,

10 shows a schematic representation of the office furniture from the front, with the

standing forces, and the schematically indicated bending line.

In the drawing, a desk 1 is shown with its various components in different positions. This Desk 1 has two U-shaped frames 3 and 4, which are screwed together by means of a cross member 6. The two U-shaped frames 3 and 4 each consist of two lateral tubes 8 and 9 and one connecting them U-rail 10, which by means of a cover strip 11 forms a coverable channel for receiving electrical lines.

Fig. 3 shows the cross section of the traverse 6, which has two lateral tubes 13, which by welding, are connected for example by means of a C-rail 10. Between the two tubes 13 and 14, supported on the C-rail 15, the removable U-shaped cover strip 16, which forms a channel, is inserted. At both ends the traverse 6 has two end plates 18 and 19 each, which allow screwing to the two U-shaped frames 3 and 4.

In Fig. 1, the electrical lines 21 are also shown. This representation shows that the access and routing of the lines through the entire frame of the desk 1 can take place. This construction also sets Assemble several units safely, each with the electrical lines from one unit without additional Work can be directed to the next.

A desk plate 23 is held between the two U-shaped frames 3 and 4. It's in four places, which one is preferable the corners of a rectangle or square

form, resiliently mounted. These bearing points 24, 25, 26 and 27 each have a helical spring in the embodiment shown 29, which are supported in corresponding spring plates 30. The spring plate 30 for their part are in the sense 6 and 7 attached to the yokes of the U-shaped frame 3 and 4, for example welded. The top Ends of the springs 29 rest in corresponding sleeves in the desk plate 23. At the ends of the two yokes to the U-shaped Frames 3 and 4 are each a locking plate 32, which is provided with a Verschxebeschlxtz 33 in the middle and have counterbores 34 on the side. The desk plate 23 in turn is provided with corresponding grooves 35, in which tie rods 36 are carried out, the heads 37 of which fit into the countersinks 34, while the shaft thickness corresponds to the width of the sliding slots 33. The ends of the tie rods 36 are fastened in spans 41, which for their part pivotably mounted in cheeks 40.

According to the desired inclination and working height of the desk top 23, it is adjusted using the special clamp 41 clamped and locked at the same time.

The desk top 23 is stabilized and locked in place by means of the tensioner 41 and the tie rods 36.

The pre-tensioning is adjusted using a tension lock side arranged thread 39. The tie rods 36 can be adjusted continuously. So that the tense The desk top maintains its desired height position or inclination even under high loads, are the heads 37 conical or hemispherical. These heads 37 engage in the specially designed Ansenkuagen 34 of the slotted Locking plates 3 2 a.

As can be seen from Fig. 10, the tie rods 36 can be tilted with respect to the desk plate 23 and by means of the tensioner 41 be stretched. Forces 43 and 44 then act from the clamping points on the desk top 23. The two Forces result in the resultant 45 pointing upwards in the middle of the desk top 23, which the desk top like presses a bar that is not freely resting at the ends, but is slightly clamped in, upwards and the indicated The preload bending line results, which of course is very much exaggerated.

When the tie rods 36 are relaxed and the desk top is unloaded, the pressure of the helical springs 29 causes it to move into their highest position. It can now be pressed down at the appropriate points and the desired position by clamping the tensioner 41 are held. In this way it is possible to lower the desk top 23 and / or as desired to tend.

The design of the frame with coverable channels enables so-called three-dimensional electrification, such as show the lines indicated accordingly in FIG. So it is now possible in all feet as well as in the horizontal Connect the cables from the ground (without running in).
