<p>A track system for fastening at the groove (2) of a mast (1) comprising 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 provided with transverse openings (17) for receiving the screws (38). The slide members (5) are adapted to be slidably arranged, however, prevented from rotating in the groove (2) and with a base (28) being engaged in the interior of the groove in the mounted state of said slide member (5) and a shaft extending through the slot (3) of the groove, and an axial threaded hole (36). The threaded hole (36) is adapted to coact with the thread (37) of a screw (38) when said thread has been inserted through the corresponding transverse opening (17) in the track (4) for fastening said 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). The recesses (22) are adapted and dimensioned for receiving the protruding portion (33) of the slide members (5) in a circumscribing manner.</p> |
