<p>Footrest with a treadboard (1) to which under side two hinged frames of tube (2, 3) are fixed. These form the legset and are dimenstioned so that one of them (2) can swing freely past the other (3). The frames are opposite the hinges and the treadboard equipped with respectively a lock catch (6) with holes (7) and a dowel (8) that fits the holes of the lock catch. Thus the frames can be kept in the desired distance. The footrest is adjustable in height by changing the mentioned distance between the frames by choosing a hole in the lock catch (6). The footrest is adjustable in angle on account of thight friction in the hinges between the frames (2, 3) and the treadboard (1).</p> |
