Abstract: A counterbalancing assembly for an article of folding furniture comprises at least one piston extending between a support assembly and a furniture component, said piston being biased to resist a downward force of gravity acting on the furniture component. An upper mounting bracket secures a first end of the piston to the support assembly, and a lower mounting bracket secures a second end of the piston to the furniture component. One or both of the upper and lower mounting brackets includes a worm gear and a mounting element that is threaded onto the worm gear. Each such mounting element has a portion adapted to engage a complementary fitting defined by a respective end of the piston, such that rotation of the worm gear causes a corresponding linear movement of the mounting element, and thus, linear movement of the respective end of the piston.

Abstract: A pivoting leg assembly for an article of folding furniture having a frame and which can be rotated between a storage position and a use position includes: a leg support bar adapted for slidable movement with respect to the frame, such that the leg support bar can move forward and rearward in a plane substantially parallel to the frame; and a leg pivotally connected to the leg support bar, such that it can be pivoted from a first position to a second position in which it extends downward and away from the frame, thus providing support to the frame in the use position.

Abstract: A folding furniture apparatus for selectively and alternatively moving a pivotally connected furniture component between a substantially horizontal usable position and a substantially vertical storage position includes a counterbalancing piston assembly and associated mounting hardware that can provide one of a selected value of torques, counterbalancing the weight of furniture component. At least one counterbalancing piston extends between an upper mounting bracket secured to a support assembly and a lower bracket secured to the furniture component, each of these brackets having a plurality of corresponding mounting points. A counterbalancing piston is pivotally secured to and extends from a selected mounting point on the lower bracket to an associated mounting point on the upper bracket.

Abstract: A self-contained underwater breathing apparatus wherein surface air is delivered through a float-supported hose to a compressor carried by the diver and powered by the diver's exhalations. The compressed air is stored in reservoirs and inhaled by the diver through a demand regulator. An auxiliary manually powered compressor is provided for startup, emergency use and to make up system losses.

Abstract: A supporting structure for articles for storage for transport wherein provision is made for the same to be elevated by the fork lift of lift trucks on any of the all four sides of the pallet.
