(57) A restraint for mounting in or on a side frame element (1, 1a) of a door opening
in which a curtain (2) is mounted comprises a bracket (4) mounting at least first
and second rollers (8a, 8b) upon respective first and second spindles below an opposed
pair of guide plates (5, 6) which define a gap through which, in use, an edge margin
of the door curtain (2) is guided in a generally vertical plane. The spindles (9,
9a) mounting the rollers (8a, 8b) extend generally parallel to each other at positions
which lie at opposite sides of the plane of the curtain (2) in use so that the rollers
mounted thereby contact opposing surfaces of the curtain. The spindles also extend
at positions one above the other, ie, at a respective upper and lower level. The second
spindle (of roller 8b) is mounted so as to be adjustable in position relative to the
first spindle (of roller 8a) so that the position of the second roller (8b) can be
adjusted to deflect the curtain (2) from its otherwise generally vertical plane when
extending through the restraint.
