| 摘要 |
The invention relates to a catch device for up-and-over door wings, the movement of which is controlled completely or partially by fixed running rails and by running rollers guided thereby and fastened to the wing. The invention is intended, in the event of the failure of essential supporting elements partially experiencing wear, to intercept the door wing and to safeguard persons or objects located under it against injury or damage. This is achieved in that there are fastened to the wing, in the region of the running-roller mounting, catch parts which make a form-surrounding connection with the running rail, at least in the effective direction of the wing forces. |
