• the brake and holding bodies designed as tapered rollers are mounted on a brake body support formed by a metal part, on which, on the one hand, the spring load required to apply the required braking and holding forces also acts, and which at the same time also the rotationally secure connection of the brake body support to the hinge pin forms.
• the support of the spring load against the hinge pin with an axially directed spur toothing of the brake body carrier in a positive, rotationally secure engagement is formed from a metal part.
• This design of a door arrester advantageously leads to a small-sized, little installation space-consuming design of a hinge-locking unit and also has the advantage of being very cost-effective to produce, but on the one hand is inadequate in that the load-bearing spring associated with the brake body carrier is concentric with the hinge pin Arranged disc spring assembly is formed and only acts on the central area of the brake body bracket surrounding the hinge pin and on the other hand has the problem of a relatively large weight.
