DE3323927A1 - Slatted unit with rotatably mounted sprung slats - Google Patents

Abstract

A slatted unit with rotatably mounted sprung slats has for each end of the sprung slats a corresponding cutout in the frame of the slatted unit. The cutouts each have an upper and a lower curved boundary surface. The sprung slats which have been inserted in the cutouts can be rotated along these curves about their longitudinal axis within a predetermined range. In order that the sprung slats are held reliably in the cutouts, even under high stresses, the cutouts are inclined by an angle alpha relative to the horizontal plane. Said inclination can be adapted to the curvature of the sprung slats present in the unstressed state. It is ensured by the inclination of the cutouts that the sprung slats are clamped in the cutouts even under low stresses such that the sprung slats may still be rotated, but can no longer slip out of the cutouts.

Description

Slatted frame with swiveling spring

The invention relates to a slatted frame, in particular for reclining furniture, with a pivoted spring.

To achieve the best possible adaptation of the spring to different To obtain strong deflections, it is known that the spring affords elastic Bearings are attached to the frame of the slatted frame.

The invention is based on the object of a slatted frame with rotatable to create stored spring strips that are as simple, stable and secure as possible Has fastening for the spring bars.

The solution to this problem is the one mentioned at the beginning with a slatted frame Genus obtained with the features specified in claim 1. By the fact that the recesses are milled into the frame with an angle of inclination, you get a special one good clamping effect between the spring strips used and the side frame parts. Slipping out of the spring afford is safely prevented in this way because the spring strips are clamped in the corresponding recesses when loaded.

Advantageous further developments are characterized in the subclaims.

The invention is explained in more detail below with reference to the drawings. 1 shows a perspective view of a slatted frame according to the invention and FIG. 2 shows a cross section through a spring strip and the frame in the area of Recess.

In the section of a slatted frame shown in FIG. 1 on the inside of the frame 1 recesses 2 milled into the spring strips 3 are inserted. The frame and the spring strips are preferably made of glued Made of wood.

The recesses 2 are designed to be widened on their narrow sides 4 and its lower boundary surface 5 and the upper boundary surface 6 are curved. The spring strips 3 inserted into the recesses 2 are corresponding about their longitudinal axis the indicated arrow direction 7 rotatable. Depending on the curvature of the boundary surfaces 5, 6, the spring strips 3 can be at a more or less large angle around their Longitudinal axis can be rotated.- A particularly good storage is obtained for the spring strips in that plastic caps 8 are fitted onto their ends, which tightly fit the ends enclose.

These plastic caps 8 have the particular advantage that when Bending of the spring afford 3 essentially no noise.

Fig. 2 shows part of a spring strip 3 with additional proper Plastic cap 8 and a frame 1 in section. The recess 2 is around one Angle inclined downward against the horizontal. The angle X is im exemplary embodiment 40 shown. This angle of inclination can be chosen so that it is adapted to the curvature of the spring strip 3, which the spring strip 3 in the unloaded State has.

If the spring strip 3 is pressed down in the direction of arrow a, so it tilts in the recess 2 and sticks to the boundary surfaces 5 and 6 fixed.

By jamming the spring bar 3 can be loaded Do not pull the state out of the recess 2. Twisting around the longitudinal axis the spring strip 3 is, however, still possible.

In this way a very simple and secure attachment is obtained of pivoted spring strips.

The individual wood layers of the spring bar 3 and the frame 1 are not shown in the drawing for the sake of simplicity.
