发明名称 Slip connector for weight actuated height adjustors
摘要 A slip connector is provided for swivel chairs, and other similar seating, of the type having a base, a seat rotatably supported thereon, and a weight actuated height adjustor, which engages when the seat is unoccupied to facilitate adjusting the seat height, and disengages when the seat is occupied to permit the seat to swivel on the base without affecting the seat height. The slip connector includes two coupling members, which rotate about a common axis when the seat swivels about the base. A stop mechanism positively interconnects the coupling members causing them to rotate together when they assume a first, angular relationship. A spring interconnects the coupling members, and biases the same when the seat is unoccupied into a second angular relationship, which is spaced a preselected angular measure from the first angular relationship, such that when the user exits the seat, the seat must be rotated through the preselected angular measure before the seat height can be adjusted, thereby greatly alleviating any unintentional height adjustment.
