Each end section (34) is anchored to the anchoring support (62, 64) by a pivoting connection or a ball-and-socket connection.

The operating mechanism further includes a pivot pin disposed within the housing.

An antenna mount is provided with a pivot base and a pivot saddle rotatably coupled to the pivot base by a pivot connection and at least one pivot arm connection.

The blister sleeve includes a pair of spaced apart planar walls defining therebetween a pivot connection.

The longitudinal member contains a pivot connection at a location between the top and bottom section.

The upper part and lower part is pivotally attached to each other at the middle or back part, and via a pivotal and slidable connection (11, 12) in the front part.

A link member (44) is pivotally linked to the first pivot point of the front structural member and the third pivot point of the rear structural member.

According to the invention, said connecting elements are designed to collaborate in such a way as to form a pivot joint, at least one of said connecting elements being a viscoelastic element.

The folding means engages the upper and lower supporting roettibers in secure pivotable relation.

The ring (18) is surrounded by a dented crown (19) to which it is connected by a pivot link oriented along the third axis (y), said crown (19) being connected to the frame (3) by a pivot link oriented along the first axis (z).

A second link (38) pivotally connects the tongue (18) with the second jaw (16).

A first link (30) pivotally connects the tongue (18) with the first jaw (14).

The rigid member can be a non-planer contact surface (14b) along which the deflection end tracks, or a pivot link (80j).

The rotor assemblies drive a planetary member (50) for rotation about its axis through a sliding pin connection (56).

The pool cleaner accessory comprises a first conduit (12) and a second conduit (14) for pivotal connection to the first conduit.
