Problems solved by technology

This can lead to a breakage of the stop or unwanted movement of the feet due to the pulsating loads in the vicinity of the stop
[0006] In addition, it is known that there are swivel chairs that do not make a full turn, because the swivel axis is displaced vertically during the swivel due to an opposing inclined plane, so that the seat surface is repositioned without load. return to initial position
However, displacement in the vertical direction and automatic return are not what people want

Embodiment Construction

[0020] The following description of a preferred embodiment is given with the aid of illustrations.

[0021] The figures show the swivel axis assembly of an armchair as a whole, designated 1 and having a swivel spindle 3 rotatable in a swivel sleeve 2 . The rotary spindle 3 has a radial groove 4 into which a pin 5 protrudes from the rotary sleeve 2 in radial direction.

[0022] A groove 4 that does not completely circle around is an incomplete “ring groove” in the running surface of the rotating spindle 3 . No recess or remaining flange 6 (see image 3 and 4 ) forms the two ends 7A, 7B of the groove, and serves as a stop mechanism for the pin 5 penetrating into the groove; the pin 5 may be a bolt structure.

[0023] The recess 4 , which does not completely circle around, has damping stop means at both ends 7A, 7B in the form of elastomer inserts 8 arranged there.

[0024] In addition, inserts 9 , 10 are designed on the upper and lower parts of the rotating sleeve 2 to reduc...

Abstract

The invention relates to a rotary shaft for a piece of seating furniture, comprising a rotary spindle (3) that is rotatably guided in a rotary sleeve (2). The rotary spindle (3) has a radial slot (4) into which a pin (5) radially protrudes from the rotary sleeve (2) and which does not extend all the way around the spindle.

Description

technical field [0001] The invention relates to a rotary shaft and a sitting piece of furniture with a corresponding rotary shaft. Background technique [0002] It is well known that swivel chairs such as office chairs should be designed so that the seating surface can rotate a full turn relative to the feet. For example patent DE1903637U has just announced a kind of such swivel chair. [0003] But what people often don't want to see is that the seat surface can rotate 360° relative to the feet, but there is no stop device, so it is easy to cause the danger of wires used for power supply or massage function being wrapped around the feet. [0004] Therefore, some seats are designed with a stop device, which consists of a bolt mounted on the underside of the seat surface, protruding outwards, and a stop element mounted on the rotating shaft. [0005] But now the problem is that this stopper is far away from the axis of rotation, so it is subjected to a lot of force. This ca...
