A stand (10) for a suntan system has a base (13) with two horizontal legs (14) at right angles, and an upright mounting member (15) extending from the base (13) but facing at an angle of 221 DIVIDED 2 DEG to the centre-line bisecting the angle between the legs. The top end of the mounting member (15) forms a face portion, inclined downwardly at 221 DIVIDED 2 DEG , and carrying a pivotal mount (12) for an arm (17), which in turn carries a panel (11) of ultraviolet lamps. A pivot pin (20) (Figure 4) on the arm (17) is inclined at 221 DIVIDED 2 DEG to the arm axis. In use, the angles between the parts are additive in some positions and cancel out in other positions. The arm can therefore have two limit positions, one directly above the centre-line of the base (13) and the other directly above one leg (14) for compact storage in the corner of a room. In each limit position, the arm is horizontal, but movement from one to the other causes a rotation about the axis of the arm, bringing the panel (11) from the horizontal position when the arm is central, to the vertical position when the arm is folded above the leg for storage. <IMAGE> |
