An adjustable fastener, preferably made from metal, for joining two structural elements (1, 2). Said fastener essentially consists of a holding element (3) comprising a relatively narrow sleeve-like ring (4), and tongue-like or ear-like members (6) projecting from the circumference of said ring (4); and a force transmitting member (7) provided with a through hole (8). Due to its special design, said holding element (3) will lock to structural element (1) and, thus, constitute a stable holding member for said force transmitting member (7). |

DETAILED DESCRIPTION We claim: 1.
An adjustable fastener, preferably made from metal, for joining two structural elements, the fastener comprising a holding element for mounting in a through bore formed in a first of the structural elements from one side of the first structural element facing a second of the structural elements, the fastener further comprising a force transmitting element, a part of which is externally threaded for threading into a holding element and which is provided with a through hole including a stop for a screw head or the like adjacent one end of the through hole, the through hole being at least in part shaped with a polygonal cross section, the holding element comprising a ring with a central axis and circumferentially spaced elongate tongue-like members projecting from one end of the ring for locking the holding member in the first structural element, the tongue-like members being internally threaded, having corrugated longitudinal edges, and being inclined circumferentially relative to the axis of the ring.
2.
An adjustable fastener as claimed in claim 1 wherein the holding element includes a collar on the ring at and end of the ring opposite said one end.
3.
An adjustable fastener as claimed in claim 1 wherein each tongue-like member has an end surface with an innermost edge and an outermost edge, the innermost edge being higher that the outermost edge.
Description:
The present invention relates to an adjustable fastener for usage when two structural elements are to be joined.
It is known to use adjustable fasteners, especially when frames, sashes or the like are to be mounted in adapted openings or in building structures etc.
Thus, GB-PS No.
1 244 498 discloses a fastener by the aid of which it is possible to make fine adjustments of the position of window frames in relation to the surrounding building structure at the same time as said window frame is secured to said structure.
The adjustable fastener according to said Specification is essentially characterized in that it consists of an externally threaded pin adjustably inserted into a threaded through hole in the window frame
