Tang-up mechanism, especially for

and lounge furniture

iadαα ^ relates to a Zalanscangen adjusting mechanism, which is used in particular to adjust the inclination of seating and reclining furniture such as deck chairs and the like.

Dex ¹ major disadvantage of the previously known rack and pinion mechanisms of this type is that one has to use both hands to change the inclination at least in one direction of adjustment and also when folding the furniture. If, for example, one looks at a deck chair of the usual design, it is necessary to lower or collapse it with one hand to hold the upper arm, to which the cloth is attached, while with the other hand the swivel bracket, whose daily the hooking pegs for the Forms racks, which are located on the rear feet, must operate.

The present invention is therefore based on the object of providing a rack and pinion adjusting mechanism with a very simple constructive structure and more convenient one-handed operation. The solution according to the invention consists essentially in that

the cream stick is a flat profile piece that is parallel to its -

Toothed surface is, is assigned and that is to this toothed surface at a distance that is at least equal Your diameter of the adjusting pin, the flat profile piece at least at one end, on which the teeth of the rack are aligned with a leaf spring bent on the side of the rack is extended so that its free end is in contact ■ with a smooth extension piece of the rack. This leaf spring has the effect that the adjusting pin no longer returns to its path after it has passed through this end can, limited by the rack and the said flat profile will.

Hau thus has an adjusting mechanism that is folded in the State only a minimal thickness, which corresponds to the thickness of the rack, assumes, with its extremely simple structure connected with the possibility of a very simple production ensures a great price fair. By the fact that the adjusting pin after passing through one end of its path, it can no longer get back into the actual adjusting path, but only must be traced back to the starting point is a creation easily possible with just one hand.

According to a preferred embodiment of the subject matter of the invention consists of the flat profile piece assigned to the rack from the lower web of an F-profile, which with its foot on one of the Side surfaces of the rack is attached and thus together with the rack two guide or pathways for the or the Forms adjusting pin, with the various settings being made by hooking into the rack in one path and in the

109820/1433

another waybann, which is separated from this as stated above, a return of the adjusting pin; happens until this one has returned to its starting point and can then return to the lower control path.

So if you want an intermediate division with this remote mechanism reaching between the previous and the starting position is sufficient it, the adjusting pin by means of the actuator provided for this purpose to the described V / eise in the initial position and then to the desired intermediate position bring. When using deckchairs or devices for adjusting the inclination of mattresses, the adjusting pins are located in the horizontal plane and their passage from the return path into the adjustment path - both paths are on top of each other - happens simply in the area of the starting position by gravity.

In applications where the transition from one path on the other hand cannot be done by gravity, is preferably the lower web of the F-profile in the area of Starting position also extended with a leaf spring which is bent in such a way that its free end is at an extension of the upper web of the F-Frofiles, so that after passage the setting pin in the starting position a return to the Krücklaufbahn is in no case possible and the adjusting pin only the possibility haberi ^ the travel path in which the toothing the rack is located to enter.

Preferred embodiments of the subject matter of the invention are readjusting with reference to the attached drawing described in more detail. Show it:

The function of the adjusting mechanism ν / ie follows from the above:

The link to be adjusted is in the starting position it is sufficient to move the locking pin 7 along the rack 2 in the direction of the arrow α and in a simple manner Way to let go when the hasty pin 7 is above the The tooth gap 2b corresponding to the corrected position is located. In the embodiment according to FIGS. 1 and 2 the occurrence of the Hast zapf ens 7 occurs in the otellvjegbahn 5 automatically thanks to the force of gravity, since this path path lies below the return path path 6;

The above is the case when this adjusting mechanism is at a A deck chair or a device for adjusting the inclination of mattresses is used, as shown in FIG. 3 is shown.

If one wants to return the member to be set in the rest position, ie the Have pin 7 i is the initial position ⁿ in the area of the end 2d traced back of the rack 2, it is sufficient to further advance the actuator in the same direction of the arrow S, as previously, the Hestzapfen 7 in the end zone 2c to guide rack 2 and then move up by raising the hasty pin 7, the elasticity of the leaf spring 11 allowing the Dur da gang of the hasty pin 7 with a brief lifting of the leaf spring end 11a so that it enters the path 6. Once the snap pin 7 is passed upwards over the free end 11a of the leaf spring 11, it rests on the extension piece of the rack 2 and prevents with absolute certainty that the pin 7 comes back into the travel path 5 and there possibly in the sense of the arrow 9 is moved back. The hasty pin 7 must therefore ζwangsnoWendig pass through the return path 6, at the end of which it then automatically falls back into the starting position at the Znhnutarigenende 2d.

If the arrangement is to be brought into an intermediate position between the starting position and the actual oüellun ^ which is just in place, the locking pin 7 is first returned to the starting position in the manner described above and from there it is brought into the corrected Sv.- isclien guelling.
