"Height-adjustable table".

The innovation relates to height-adjustable tables with four free-standing, straight legs, in which a multi-stage height adjustment is achieved by extension pieces from the feet provided with protective sleeves are pushed out, which, guided inside the legs by bumpers, housed in the frame box Mechanism can be operated simultaneously and evenly.

Belcanned versions of this type are designed so that a mechanism arranged in the frame buttons acts on the bumpers via an intermediate heal and corner. This lever mechanism in its o-esaatheit, however, has the kachieil, that firstly it takes up space otherwise required and therefore makes the accommodation of trains, optionally in the longitudinal or transverse direction, or folding inserts at least very difficult, if not completely impossible. Second, this mechanism and its fulcrums are individually mounted on two opposing sides, which requires a very precise mounting, otherwise the table as a result of längenuntersehieden in _(is not the legs firmly. Past insurmountable but seem at first, and

second, cited © Ä Difficulties when it comes to today generally. required gradual height adjustment acts "'

Dio! Fire eliminates these disadvantages «This is what happens» that the Yerstellbewegung the drive mechanism bycl one bent in one of the bend deflection Holir filled with megungselastiaclies, in longitudinally aligned aljea? Element deflected and in Eßhtung- deä? Bumpers

it will be achieved that all transmission networks are omitted for movement and thus their precise fastening aia barge cages »In addition, the means of transmission used takes up very little space in height and leaves the whole tree within of the frame trim for executions isvLT Enlargement of the OÜsohplatte through pull- outs with slide bars or Elappeinlays with guide tunnels free *

As the transmission element in the above sense, a helically wound 3) frame with adjacent turns - hereinafter referred to as "spiral" for short - with a slightly smaller outer diameter than the inside diameter of the guide tube is used, because this guide tube is used The gate part of the cheapness connects with that of a convenient anäohlusgmÖ'gliohkeit the drive organs. Ba expire two Inden of the pipe in a straight line "to also serve as guidance entry for bieguiigssteife Bsmakstäb ©, you can these bars with a corresponding (Jewinde provided * on the spiral is screwed Bin unwanted release of this Verbin. *" Is dung doing prevented by the well-known effect of seibath inhibition *

Furthermore, it is proposed that the pressure rod running in the sisal bone be stored in a metal sleeve zvl arranged in the lower end of the sisal bone and the protruding end with the

mx cement *

In this way it is achieved "that clamping is safe * because EoIz does not use solder for the guide and the precise and safe attachment of the extension pieces can be carried out without time-consuming adjustments"

As a multi-stage Terstelliaeöhanisjnus one can advantageously see two opposing toothed racks with two tooth flanks running vertically in the direction of movement, which are driven by a sprocket and one end of which is guided by means of a bolt in a slide of a bearing plate, each of these bolts serving at the same time legs as Ansohlusspunkt for two struts of two benaoKbarter, the ■ extension pieces oxidase by this Torriöhtung all animal! table legs are pressed simultaneously, no * the legs located in the whalebones of 'J? ühruiigSi pipes are to the X-ängsachse a small ITmfe- nge swivellable, in order to be able to adapt eioh the Terlagörting of the Zraftangrif ^ sispunktes *

In the following, an example of inflation is shown below. Descriptive reference to the drawings, namely shows

A table leg 1 with a protective sleeve 2 at the bottom * is that? Pierced lengthwise .

In the legs 5 a round rod 3 eats _f displaceably mounted which is guided in a bushing 10 of the fish bone 1 and is cemented at its lower end in an extension piece 11 with Sleitstopfen. Era upper lündo of the dog rod 9, a wire spiral 13 is attached, which can be moved with little radial play in the curved! are with their eyes 15 on a So.1 * Ken 16 on the land of a toothed rack © 17 * which is guided in a slot 18 of a base plate 19. Two such toothed racks 17 are driven in opposite directions τοή a sprocket ZQ ? on whose shaft 21 an operating lever 22. The operating lever engages in a spring (not shown) after a certain angle of rotation has been covered *

To lift the fish, the operating lever 22 with the Sprout wheel 20 rotated in a proper sense »where; each 180 ° from E & · * ste to Sas te correspond to a single & a altitude level, wpduröh the racks 17 move outward and the other Bolt 16 hinged ram 14 into the surface area β 4es EohafeS 4 push »Pie movement will be on the sioh's.

As can be seen, the mechanism allows one or more Intermediate positions closed. The two end positions of the tube 4 with the plunger 14 are shown in FIG.
