  • Track system to be fastened to a groove in a spar
    Patent number: 5546881
    Abstract: A track system for fastening at the groove (2) of a mast (1) includes a profiled track (4) and a plurality of slide members (5). The track (4) is formed to receive cars (12) in an axially slidable manner and is provided with transverse openings (17) for receiving the screws (38). The slide members (5) are adapted to be slidably arranged, however, the sliders are prevented from rotating in the groove (2) via a base (28) being engaged in the interior of the groove in the mounted state of the slide members (5) and a shaft extending through the slot (3) of the groove. The slide members include a threaded hole (36) adapted to coact with the thread (37) of a screw (38) when the thread has been inserted through the corresponding transverse opening (17) in the track (4) for fastening the track (4) to the mast (1). On the surface (34) adapted to face the groove (2) the track is provided with recesses (22) coaxially arranged with the transverse openings (17).
