Folding handrail system for telescoping seating systems
First Claim
1. In combination with a telescoping seating system having a plurality of rows movable between an extended use position in which said rows are in stepped relation and a retracted position in which said rows are in superposed relation, a telescoping handrail comprising at least a pair of posts, one mounted to an upper row and the other to a lower row, a handrail comprising a plurality of telescoping tubular elements forming a rail assembly;
- means for pivotally mounting the lower end of said rail assembly to one of said posts;
a sleeve slidably received on the uppermost tubular element of said rail assembly; and
link means pivotally connected at one end to said sleeve and pivotally connected at the other end to the other of said posts.

Abstract
A plurality of telescoping tubes form a rail assembly which is pivotally connected at its lower end to a post, a sleeve is slidably received in the uppermost tube which is provided with an upper stop ring and a lower ring to limit the motion of the sleeve. A link is pivotally connected between the sleeve and an upper post. Thus, as the seating system is extended for use or retracted for storage, the handrail also extends and retracts. A stop element on the link limits the position of the link in the extended position so that the axes of upper and lower rail assemblies are aligned. In a preferred embodiment, the posts are inclined forwardly so that the rail assemblies are vertical in the storage position.
