Abstract: A chair having a base, a seat support member, a seat, and a height adjustable mechanism is disclosed. The height adjustable mechanism includes a vertically extendable and compressible gas spring having a pin located at the upper end of the spring. The pin operates a valve integrated in the gas spring so that the effective length of the spring is adjustable when the pin is depressed. An elongated actuating rod is mounted to the seat support member transversely of the gas spring. A lever is pivotably mounted to the seat support member between the actuating rod and the pin. The lever is pivotable to and between a first position where the pin is depressed for adjustment of the height of the seat and a second position where the pin is not depressed. Upon rotation of the actuating rod, the pin is depressed and thereby vertically moves the seat relative to the base.

Abstract: A chair comprises a base, a column on the base, a housing on the column and supporting a chair seat and back, a height adjustment means mounted to and between the base and the housing for longitudinal adjustment to alter relative height of the seat. The chair also includes a tilt adjustment means comprising a chair back support means pivotally mounted to the housing for movement between upright and reclining positions, means for biasing the chair back support means in the upright position, tension control means movably engageable with the biasing means for adjusting tension thereof and tilt actuating means movably mounted to the housing for actuating movement of the tension control means. The tilt actuating means comprises an elongated rod rotatably mounted to the housing. The height actuating means comprises an elongated tube rotatably mounted to the housing in telescopic relationship to the actuating rod.

Abstract: A heater assembly and mounting arrangement are provided for a clothes dryer in which a heater box carrying the heater element is positioned within the dryer cabinet and is accessible for servicing and replacement from the front of the dryer. A rear end of the heater box slip fits into an air conduit which channels heated air into the dryer drum. The heater box is secured by a single bracket near the front of the dryer. The heater element is separately removable from the heater box, being slidably mounted between opposed grooves in the box and secured by a single threaded fastener.
