DETAILED DESCRIPTION OF THE DRAWINGS

[0028] The figures show an example of an inventive hoist point anchor. The hoist point anchor comprises a cruciform base 10 comprising a node portion 17 and four mounting arms 18, each of which projects from the node portion 17. The base 10 has a flat contact surface 11 intended to be placed adjacent to a flat ceiling 1. The contact surface 11 consists of four separate sub-surfaces, wherein one of these sub-surfaces is arranged on each mounting arm 18. In each of the mounting arms 18, in particular in an end portion of the respective mounting arm remote from the node portion 17, is provided a through anchor hole 19. The anchor holes 19 are intended to receive anchor bolts 9 for anchoring the base 10 to the ceiling 1. Each anchor hole 19 originates from and is surrounded by a sub-surface of the contact surface 11. Thus, the contact surface 11 is located remote from the node portion 17.

[0029] The base 10 preferably consists of cast metal, which might additionally be coated. In particular, the base 10 is monolithic.

[0030] The hoist point anchor moreover comprises a wire rope 20 having a first end region 21 and a second end region 22. The wire rope 20 is disposed in the form of a wire rope loop 28, which is wrapped around the base 10, in particular around its node portion 17, i.e., the base 10, in particular its node portion 17, passes through the wire rope loop 28. The wire rope loop 28 has a slack portion, which projects from the base 10 at the underside of the base 10, i.e., at the side of the base 10 opposite the contact surface 11, and this slack portion forms an eye for attaching a hook. In the present embodiment, the legs of the wire rope loop 28 (i.e., the end regions 21 and 22 of the wire rope 20) overlap in side view along the axis of the wire rope loop 28, but this is an example only.

[0031] The first end region 21 of the wire rope 20 and the second end region 22 of the wire rope 20, respectively, point into opposite directions. Both the first end region 21 of the wire rope 20 and the second end region 22 of the wire rope 20 are disposed parallel to the contact surface 11. The first end region 21 of the wire rope 20 and the second end region 22 of the wire rope 20 are also parallel to one another.

[0032] The first end region 21 of the wire rope 20 is disposed in a first ferrule 31 and connected thereto, and the second end region 22 of the wire rope 20 is disposed in a second ferrule 32 and connected thereto, wherein the connection to the ferrules 31, 32 can for example be a swaged connection.

[0033] The base 10 comprises a first ferrule receptacle 13, in which the first ferrule 31 and the first end region 21 of the wire rope 20 are disposed, as well as a second ferrule receptacle 14, in which the second ferrule 32 and the second end region 22 of the wire rope 20 are disposed. Both ferrule receptacles 13, 14 are open towards the flat ceiling 1 to which the base 10 is attached.

[0034] The first ferrule receptacle 13 is laterally delimited by a first fork 15, through which the wire rope 20 passes. The first fork 15 is wider than the wire rope 20 but narrower than the first ferrule 31. The first fork 15 thus forms a counter bearing which secures the first ferrule 31 and therefore the first end region 21 of the wire rope 20 to the base 10. In analogy, the second ferrule receptacle 14 is laterally delimited by a second fork 16, through which the wire rope 20 passes. The second fork 16 is wider than the wire rope 20 but narrower than the second ferrule 32. The second fork 16 thus forms a counter bearing which secures the second ferrule 32 and therefore the second end region 22 of the wire rope 20 to the base 10. A separate bolted fixing plate 40 secures the wire rope 20 in the forks 15, 16.

[0035] The base 10 has two thimble grooves 50, in which the wire rope 20 is disposed. The thimble grooves 50 guide and laterally support the wire rope 20. In particular, the thimble grooves 50 form a constriction in the base 10, in particular in the node portion 17 thereof. The thimble grooves 50 constitutes an integrated thimble for stabilizing the wire rope loop 28.
