Abstract
A device has two anchor sleeves (3) in a concrete wall (2) accommodating two parallel anchor bolts (6) of a U-shaped step iron (1) form-fittingly. Between coupling parts formed by the anchor sleeves (3) and the anchor bolts (6), a detent assembly (7) has at least one detent tongue (8) sprung in the radial direction on one of the coupling parts (3, 6) and a detent recess (9) that receives the detent tongue (8) on the other coupling part (6, 3). A guide surface (15) for the detent tongue (8) is inclined in the peripheral direction and extends in the radial direction over the engagement depth of the detent tongue (8) adjoining the detent recess (9) at least in a peripheral direction.
Claims20
A device for fastening a step iron in a concrete wall, having said device comprising:
- two anchor sleeves being supported in the concrete wall;
- the step iron being generally U-shaped and having two parallel anchor bolts each form-fittingly accommodated by a respective one of the anchor sleeves, wherein each of the anchor sleeves and the one of the anchor bolts accommodated thereby forming a respective set of coupling parts, and
- a detent assembly between the coupling parts of one of the sets that includes at least one detent tongue that is sprung in a radial direction and is supported on one of the coupling parts of the set, and structure on the other coupling part of the set defining a detent recess that receives the detent tongue, and
- wherein a guide surface for engageable with the detent tongue and being inclined in a peripheral direction and extending in the radial direction over an engagement depth of the detent tongue adjoins the detent recess at least in the peripheral direction.
