Abstract
A running mechanism which travels on a running rail comprising a web and a flange. Running wheels are supported by the flange on opposite sides of the web and are rotatably mounted in frame parts which are connected by an articulation arranged below the running rail such that the frame parts swivel open or closed laterally about a swivel pin. A load acts on at least one of the frame parts at the height of or below the swivel pin and holds the frame parts swiveled closed towards the web on both sides by means of a closing moment generated by the load. Guide rollers, one of which is rotatably supported in the frame part, are supported on opposite sides of the web.
Claims13
A running mechanism for operative interactive movement along a running rail including an upper subtantially horizontal flange disposed above a lower substantially horizontal flange and a web substantially vertically extending between the upper flange and the lower flange, said running mechanism comprising:
- two frame parts jointly connected to one another below the running rail by a swivel pin disposed below the running rail and extending in a direction of the running rail through an end of each of said frame parts thereby defining an axis of rotation about which said frame parts laterally swivel open and closed with respect to one another;
- a running wheel rotatatively mounted on each of said frame parts and disposed so as to be supported by the lower flange on opposite sides of the web;
- and
- a guide roller rotatively mounted on each of said frame parts on opposite sides of the web;
- said frame parts being swiveled closed and said guide rollers contacting opposite sides of the web in response to a closing moment produced by a load being applied to one of said frame parts.
