摘要： A counterbalance system (25) for a door (D) movable between a closed position and an open position having an axle (20), a cable drum (15) attached to the axle, a winding shaft (35) interconnected with the axle by a counterbalance spring (26), and a pawl (70) selectively movable between a first position for adjusting tension in the counterbalance spring and a second position for preventing rotation of the cable drum upon failure of the counterbalance spring, thereby limiting movement of the door toward the closed position.

摘要： The present innovation deals with a balancing and equilibration device for suspended elements, in particular for doors of pieces of furniture and windows that can be moved vertically, to allow an easy movement of same and their balanced positioning at any point of their vertical travel. A main feature of this invention is that of winding up the supporting ropes (8) of the element (6) to be translated in spiroid rims (10C) of a pair of opposing pulleys (10), said pulleys (10) being integral with each other via to a shaft (12) that is rotatable on a bearing structure (1 - 2), said shaft (12) being concentric to a helical spring (22), that comprises one end (22A) integral with said shaft (12), while the other end (22B) is integral with the basis (31) of a friction disc (30), that can be blocked to its support (5) to block the other end (22B) of the spring (22), whose opposite side is bound to turn with the shaft (12), in order to increase or decrease its torsion reaction with the changing of the movement of the pulleys (10), assuring in that way the balancing of the balanced translation of the element (6) on a frame (7) to be vertically covered or uncovered.

摘要： Dispositif de guidage pour un contre-poids d'equilibre, qui est loge dans une poutre profilee en forme de caisson, en particulier pour un tableau mural. En outre, la poutre profilee creuse a sur sa face interieure un guide longitudinal (17, 18). Des bandes (30) elastiques, faites en caoutchouc durci vulcanise sont disposees au-dessus et au-dessous du contre-poids (20) et sont fixees legerement, de maniere coulissante aux guides longitudinaux: ces bandes guident le contre-poids dans son mouvement ascendant et descendant.

摘要： An overhead door apparatus (10) utilizing a torsion spring counterbalancing mechanism (30). The counterbalancing mechanism (30) includes a worm drive ring-shaped gear winding mechanism (38) for setting the appropriate torque or number of winds in the spring (32). A counting mechanism (140) is provided to indicate to the installer the number of winds being given to the spring (32). Means are also provided for accommodating spring growth and contraction during winding and unwinding using the winding mechanism (38) and during normal raising and lowering of the door (12). A spring clip gear retainer (82) is disclosed for preventing rotation or creep of the worm drive gear (70) and spur gear (56) during normal raising and lowering of the door (12). A second embodiment is disclosed allowing more universal interchangeability of components between the left and right sides of the door system (200), easy snap-in assembly, and including a telescoping spring cover (252). Each embodiment includes a spring winding counter (140).

摘要： A guiding device for a balance counter-weight, housed into a box-girder, particularly for a wall board. Further, the hollow section girder has on its inner face a longitudinal guide (17, 18). Elastic straps (30), made of cured hardened rubber, are arranged above and below the counter-weight (20) and are fixed in a sliding manner to the longitudinal guide: these straps guide the counter-weight in its upwards and downwards motion.
