Problems solved by technology

A disadvantage of this type of braking device is that the user must individually perform the actuation of the brake, which in some cases is rather complicated in order to ensure that the unit is secured against unintentional movement
Unexpected results or even accidents cannot be ruled out if the user forgets to activate the brake, for example if the user leans or sits on a piece of furniture that is not sufficiently secured against rolling

Embodiment Construction

[0038] A chair as a movable unit according to an embodiment of the present invention is in figure 1 is represented by 10 as a whole, and the chair includes a seat 12 for receiving the force of the user's weight as a loading force K, a plurality of rollers 16 as grounded members for rolling supporting the chair 10 on the ground U A foot 14, and a central post 18 extending vertically between the seat 12 and the foot 14. In a known manner, the seat 12 is rotatable relative to the foot 14 about the vertical main axis H of the central column 18 (central axis of the central column 18 ). Furthermore, a height adjustment mechanism 20 may be provided to set the height of the seat 12 above the ground U. As shown in FIG. The height adjustment is possible by means of a known pneumatic spring 22 extending along the main axis H and actuated in a known manner by a first actuating lever 24 .

[0039] According to the invention, the chair 10 also comprises a braking body 26 movable between a...

Abstract

Operating controls for actuating the brakes and in particular the movable unit of the chair. The invention provides an operating control (28) comprising a brake body (26) adjustable between a brake position and a release position in which the brake body (26) is in contact with the brake frictional contact with a moving surface (U) from which the brake body (26) is pulled back in the release position; a load input (22) which is set to receive input from the and a load trigger mechanism (42; 46), which converts the loading force acting on the load input (22) into the brake body (26) from the release position to the brake The adjustment movement of the moving position.

Description

technical field [0001] The invention relates to an operating control comprising a brake body adjustable between a brake position and a release position in which the brake body is in frictional contact with a brake surface, in which The braking body is pulled back from the braking surface in the release position; a load input is configured to receive a loading force from a user; and a load trigger mechanism acts on the load input The loading force of the brake body is converted into an adjustment movement of the brake body from the release position to the brake position. The invention also relates to a mobile unit comprising an operational control of the type by means of which the movement of the mobile unit along the ground can be braked. Background technique [0002] Operating controls of the above-mentioned type are known in the prior art, for example in the form of foot actuatable brakes on rollable carriages or other furniture. As the load input is loaded by the user's...
