## Abstract

A frame of a furniture is disclosed, comprising a bearing, which is provided for rotatably mounting of a foldable pillar about an axis, and a fixation which is provided for receiving and fixing the foldable pillar. The frame is designed in a way, that fixing can be realized by clamping of a fixation equipped with an eccentric. Moreover a securing element is disclosed, which can be brought in a securing position by a lever, whereby the lever thereby simultaneously causes the pillar to be clamped in the frame.

## Claims

### Claim 1

A frame of a furniture, comprising:
a bearing system that rotatably supports a foldable pillar around an axis,
a fixation that receives and fixes the foldable pillar, whereby the fixation fixes the foldable pillar by clamping,
a securing element configured to secure the pillar in a predetermined position by positive engagement through meshing in a pin hole of the pillar, and
a lever that presses the securing element into the pillar, wherein the fixation comprises:
a first clamping element connected to one end of a connection element;
a second clamping element loosely mounted on the connection element;
an adjusting element adjustably connected to another end of the connection element; and
an eccentric movable along an axis of the connection element between the adjusting element and the second clamping element, wherein the distance between the adjusting element and the first clamping element is variable so that a strength of a clamping effect of the eccentric is adjustable.

### Claim 2 (depends on 1)

The frame according to claim 1, wherein
the frame is configured such that the foldable pillar can be clamped between at least two portions of the frame by the fixation.

### Claim 3 (depends on 1)

The frame according to claim 1, wherein the securing element is configured to maintain a folded state in which the pillar is secured in the frame.

### Claim 4 (depends on 1)

The frame according to claim 1, further comprising a spring, wherein the spring is positioned in a way that it acts on the securing element in a direction of a position that does not secure the pillar.

### Claim 5 (depends on 1)

A furniture with a frame according to claim 1, wherein the foldable pillar comprises:
at least one round hole to allow the pillar to be rotatably mounted around an axis by means of the bearing system of the frame, and
at least a U-shaped recess for receiving and fixing the pillar by means of the fixation of the frame.

### Claim 6 (depends on 5)

A furniture according to claim 5, wherein the pillar further comprises a securing hole through which a securing element is inserted to secure the pillar.
