In a vertically adjustable chair, having a telescopic support column controlled by a compressed gas cartridge 14, brake shoes 24 are mounted on longitudinal resilient fingers, formed by slots 25 in tube 13, and urged radially outwardly, by the wedging action of tapered thrust member 16 on balls 22, to grip the inner wall of stationary outer tube 12. On lifting arm 30 to lower cartridge 14, the braking pressure is relieved, by the descent of member 16, to allow the balls 22 to move radially inwardly under the pressure of the resilient fingers. The seat, thus freed, rises under the action of the gas in cartridge 14, driving piston rod 32 against base member 33. The brake is re-applied at any position of adjustment, by releasing lever 30. Spring 18 provides a resilient support for the seat.

The effects of bounce in contacts 12, 14 is avoided by opening contacts 13, 15 when the closure of 12, 14 is initiated so as to actuate a device 17 which delays the start of the voltage applied to the contacts. The delay may be provided by a delay line or a mono-stable circuit. In Fig. 2, operating any of the pushbuttons 21 connects the output line 26 to a terminal 25, but first breaks at contact 23 and thus the short circuit across capacitor 28. The capacitor accordingly charges and when its voltage reaches the threshold level of an inverter 30 it triggers a mono-stable circuit 27 to provide an output pulse. An inhibit or timing pulse may be applied to 47. If a number of the buttons must be effective simultaneously, contacts 23 are omitted and a separate series of break contacts are provided.

For locking, partially rotatable ring 79 is held in grooves 81, 83 in handle 15 and cover 37 respectively, rotated by finger pieces 85, 87  projecting through slots 89, 91; detent pin 93 springing into recess 95 or 97 locates the ring. With pin 93 in recess 95, lugs (109 and 107, Fig. 4, not shown) on the plug member can pass through the ring, allowing disengagement; with pin in recess 97 and connectors engaged the lugs are trapped behind shoulders 111, 113 on the ring. To provide permanent engagement, the ring may be fitted over the plug member and assembled into the appliance rotated through 180 degrees, the detent pin 93 being located in recess 94; engagement can then be released only by dismantling. A design of plug member for heavier duty has smaller body parts then those in light duty design, and the corresponding appliance fitting has larger mating projections (631, 69<SP>1</SP>, Figs. 16, 17, not shown). The heavy duty plug member can therefore be inserted into either design of receptacle fitting, but the light duty plug member mates only with its counterpart.
