Patent EP-0256837-A3 (EP)
IPC: A47C4/38
Filed: 1987-08-11
Abstract: The present invention provides a foldable frame assembly, 
comprising a pair of complementary X-shaped side frames each 
having two bar members (1, 2, 1′, 2′) hinged together 
intermediate their ends to permit folding and unfolding in the 
plane of the X, the two side frames being mutually parallel and in 
register with each other; and a pair of centrally hinged 
transverse X-frame support stays, each having two substantially 
straight stay members (4, 5, 4′, 5′) hinged together 
at their mid points (6, 6′) to permit folding and unfolding in the 
plane of the X which is perpendicular to the plane of 
the side frames. An end of each stay member is hinged to an end of a 
side frame bar member so as to permit pivoting both in 
the plane of the stay members and in the plane of the respective bar 
members, whereby folding and unfolding of the side frames 
causes simultaneous and corresponding folding and unfolding of the 
support stays. The foldable frame can form the basis for a 
foldable seat or a foldable chair.

(27) is operated, the control section makes the tone 
generator stop generation of the audible tone. The 
controllable volume may be controlled by operation of a
