"Infinitely height-adjustable table"

The invention relates to a continuously variable height Table, especially for the physically handicapped.

7524909 03/04/76

Eb height-adjustable tables are known. An acquaintance Embodiment is that between the table frame and the table top two scissor hinges are arranged, with the help of a spindle drive and corresponding toggle lever handlebars can be raised.

In the case of the training, however, a relatively large number of revolutions are required the spindle of the spindle drive to bring the table to the desired height; also requires the adjustment mechanism of this type a relatively high construction cost.

The invention is based on the object of a BtufenloB To create a height-adjustable table that is less expensive is in the production and in which the height adjustment can be done easily and without great turning effort.

According to the invention this is achieved in that between Table frame and table top a parallel link device is arranged by dis the raising of the table top dbbi towards will. There is one short handlebar on the table frame the parallel steering device and the other on the table top arranged short handlebars, both short handlebars are connected by two parallel handlebars.

At right angles to one of the handlebars it is movable Arranged control rod, which rests loosely with one end of the other Lenkatange.

According to an exemplary embodiment, the longitudinal displacement can the control rod by a known calibration Spindle drive is achieved by inserting a handlebar in one of the steering rods a thread is arranged which cooperates with a screw arranged on the control rod.

As a result, the distance between the steering rods and their entire position together with the table top can be adjusted by turning the control rod changed uiBrden.

The advantage of the height-adjustable table of the invention Art beateht that only by a few rotary movements of the control rod for the purpose of adjusting the two parallel handlebars aB considerableB height adjustment is achieved. For example, when adjusting the parallel Handlebars by 25 mm, the table top is height-adjusted by 160 mm will.

The construction effort is low, since only to adjust the hoist this parallel link device is required.

At the end of the control rod there is a low friction bearing Running means, e.g. a roller, preferably a ball, dia on the other handlebar, preferably on one attached to it hoarded running plate. This formation ensures the ease of movement of the adjustment mechanism BSBa safe when setting up the table.

In addition, the invention has a height-adjustable Table has the advantage that the V / creation mechanism, i.e. the Spindle for turning the spindle drive from the chair of the Is easily accessible to the user; the user therefore does not need the tabletop when rSShsnvsrstellen to get up.

Since the adjustment mechanism, in particular the crank for Adjustment of the spindle drive in the middle under the table top such tables can be placed next to each other without any spacing. This allows the, for example in a school, optimal use of the available space uierdan.

The height-adjustable table according to the invention is not suitable only for schools and for other purposes but in particular also for the physically handicapped, as dip for those seated at the table Crank for adjusting the spindle drive is easily accessible. Therefore, blind people do not need this crank search.

On the table top itself, a swivel arm can be articulated, which carries a horizontal side table top, so that a typewriter, for example, can be arranged on this side table top. The pivotability of the swivel arm gives the user of the table the opportunity to easily access the devices arranged on the adjacent table top are, which is particularly advantageous for the physically handicapped.

FIG. K shows a side assembly of the height-adjustable table according to the invention with the swivel arm.

With 1 iat the Tischgeetell denotes that after the belpplelaueisen Embodiment consists of two columns 2, which are connected at the top by a cross member 3, the columns 2 have the foot part 2a at the bottom.

In the middle of the QuBrtravarss 3, the parallel link device denoted overall by k is arranged (see also Fig The end are also connected by a short link B - to which the table top is attached, for example with the help of a U-rail 9.

Transverse to the one handlebar 6 is designated as a whole by 10 Longitudinal & displaceable control rod arranged. At the end of Control rod 10 supports a ball 11 which is attached to the handlebar 7,

preferably bears against a gahlrtvtan running plate M attached to it (Fig, 3).

The lBngavereGiebllche tax length 10 let in detail ale spindle drive is formed by providing a screw 12 let that provided with a in the handlebar 6 Geuiinde 15 cooperates.

You turn the crank 13, then you move it Control rod in its axial direction, like that in Fig. illustrated let. This reduces the distance between the handlebars and 7 changed.

Since when turning the crank 13, the ball 11 on the running plate 1 <t there are few friction points to overcome. This means that the adjustment mechanism has to be used to raise the table top 16 extraordinarily easy-to-use.

On the table top can after a swivel arm 17 for a horizontal ancillary plate 16 may be arranged. This is the user will be able to swivel dBS Schit & nkarmee pulling the table top towards you or pushing it away from you.
