摘要： A counterbalance system for a side load window assembly having a window sash and side frame jambs. A spring carriage is provided. The spring carriage has a first section that fits into a gap space between the window frame and the window sash. The spring carriage also includes a second section that passes under the window sash, therein supporting the window sash. At least one coil spring is provided. Each coil spring has a wound body that is held within the spring carriage. Each coil spring also has a first end that extends out of a housing and is anchored to one of the side frame jambs. The coil springs bias the spring housing upwardly. Since the window sash rests upon the housing, the window sash is counterbalanced.

摘要： An apparatus and method to substantially cancel out the opposing torsional forces of the torsion spring of a spiral rod subassembly and the extension spring of a compound spiral rod balance on the carrier element. The extension spring and the rod spiral balance subassembly are parallel, connected at their lower ends to a carrier element and at their top ends either to an upper mounting cap or separately to the wall of the jamb channel. The spiral rod is turned a pre-determined number of times in a direction opposite from that in which the extension spring is turned so that the torsional forces acting on the carrier element from the torsion spring and the extension spring substantially cancel out each other. The balancing out of the counteracting torsional forces eliminates or substantially reduces the friction between the carrier element and the jamb channel.

摘要： Window sash counterbalances using curl springs and holders can increase resistance to sash drop without causing sash hop by using a high coefficient of friction bearing surfaces against which curled up coils of curl springs slide when uncurling or re-curling. The higher friction bearing material produces more frictional resistance to spring uncurling than to spring re-curling and thus resists drop without causing hop. This allows a wider range of sash weights to be counterbalanced by a fewer number of counterbalance forces, saves manufacturing cost.

摘要： This invention relates to a spring balance, and in particular to a spring balance for use with a sliding sash window. The invention provides a spring balance comprising a top assembly which is securable to a frame member, a bottom assembly which is securable to a sliding sash, a tension spring connected to the top assembly and to the bottom assembly, a torsion spring, a spiral rod, and a follower bush interconnecting the spiral rod and the torsion spring. The spring balance is adjustable at the top assembly, and includes a limit mechanism for limiting the range of adjustment, the limit mechanism preventing over-adjustment of the spring balance.

摘要： Disclosed is a multi-coil spring assembly that is mounted in the weight pocket of a vertically operating window. The multi-coil spring assembly allows the user to attach a desired number of multi-coil springs having chosen constant forces to the counterbalance connector to provide the desired amount of counterbalance force to the sash of a vertically operating window. The multi-coil spring assembly may be rotated into an interior portion of the window to permit straightforward attachment to the counterbalance connector and then retracted into the weight pocket in a recessed position for normal window operation.

摘要： The present invention relates to inertial braking system for spring-loaded devices, such as block and tackle window balances incorporated in single and double hung window assemblies. In one embodiment, a block and tackle window balance includes a translatable block assembly disposed in a track including a pawl pivotally attached to the translatable block assembly. The pawl, in response to a rapid acceleration of the translatable block assembly, rotates about a pivot and frictionally engages the track, thereby wedging the translatable block assembly in the track. In another embodiment, the translatable block assembly includes a cam attached to the pawl and a brake shoe disposed between the cam and a cord seated within a pulley. Rotation of the pawl causes the cam to translate the brake shoe, thereby compressing the cord against the pulley.
