摘要： A telescopic leg which is adjustable in length comprising three relatively slidable sections. A releasable friction jamming mechanism acts between a pair of the sections whereby one section can be pulled out or pushed into the other section of the pair and secured in position by the jamming mechanism. Relative sliding between one of the pair of sections and a third section permits these two sections to be slid into an extended or a retracted position, and releasable locking means allows these two sections to be secured in either the extended or retracted position. Where the leg sections are of circular cross section relative rotation of one section relative to the other is prevented. The three sections comprise an inner section, slidable in an intermediate section, and an outer section in which the intermediate section is slidable and the friction jamming means is mounted at the lower end of the outer section to lock the intermediate section at any desired position relative to the outer section. The releasable locking means acts between the intermediate and inner sections. The inner section includes a hinged foot at one end. The three sections are of similar length, and the inner section is prevented from fully leaving the intermediate section, and it is prevented from fully leaving the outer section. The friction jamming means includes a spring loaded apertured lever which is biased into jamming engagement by the spring and is released from that engagement by lifting up (or pressing down) the lever against the action of the spring so that the lever becomes perpendicular to the leg section.An angler's bed-chair can be fitted with two pairs of multiple section legs one pair on each side of a central section on which an angler will normally sit. The jamming lever is located within a housing having an opening in one face to give access to the lever.The housing surrounds the leg section in the region of the lever. The latter can be wholly contained within the housing so that the it cannot be operated accidentally nor protrude so as to catch on clothing or cause injury. This protected lever arrangement can be incorporated into a telescopic leg having only two sliding sections
