发明名称 IMPROVED SLIDING ANCHOR
摘要 The invention relates to a sliding bolt (10) for introducing into a bore, having an anchor rod (12), on which is disposed a sliding control element (14) with a through-opening (18), through which the anchor rod (12) extends, wherein the sliding control element (14) comprises a sliding body cage (16) having at least one recess (20) for receiving a sliding body (22) that is in contact with the lateral surface of the anchor rod (12), and having an anchor plate (24), which is intended to lie against a region surrounding the mouth of the bore once the sliding bolt (10) has been introduced into the bore. In contrast to conventional sliding bolts, the anchor plate (24) is in load-transferring connection with the sliding body cage (16), with the result that it is easily possible to provide a device that indicates a sliding path of the sliding bolt that is still available.
