T-shaped rail for a runner at a fixed ladder, as a protection against falling, has projecting studs at one end of a rail length to fit into drillings at the neighboring length, to give a seamless joint for smooth running

摘要

The T-shaped rail (1) for a runner at a fixed ladder, for protection against falling, has at least one projection (3) at the lower end for a positive fit at the connection to the neighboring rail length. The projection has two profiles (5), as vertical studs, each at the corners of the stem (6) of the T-shape, at the lateral bar (7) to flank the stem. The upper end of the rail length has two drilled openings to take the studs of the adjacent rail length.
