Hinged axle pulley release for inline cable fire pull station
A manual activation system includes a bracket rotatable about a first axis between a first configuration and a second configuration and a pulley movable between an inactive position and an active position. The pulley is mounted to the bracket and is rotatable about a second axis. A tension member is wrapped about the pulley and has a tensile force acting on the pulley. An activation member is configured to cooperate with the bracket to selectively oppose the tensile force.
1 . A manual activation system for use in a fire suppression system, the manual activation system comprising:
a bracket rotatable about a first axis between a first configuration and a second configuration;
a pulley movable between an inactive position and an active position, the pulley being mounted concentrically about the bracket and being rotatable about a second axis;
a tension member wrapped about the pulley, the tension member having a tensile force acting on the pulley; and
an activation member configured to cooperate with the bracket to selectively oppose the tensile force.
2 . The manual activation system of claim 1 , wherein the first axis is oriented orthogonally to the second axis.
3 . The manual activation system of claim 1 , wherein the pulley has a central hole aligned with the second axis, the bracket being receivable within the central hole.
4 . The manual activation system of claim 1 , wherein the pulley is rotatable about the second axis relative to the bracket.
5 . The manual activation system of claim 1 , wherein the pulley is rotatably coupled to the bracket.
6 . The manual activation system of claim 1 , wherein the bracket includes a groove and the activation member is receivable within the groove when the bracket is in the first configuration.
7 . The manual activation system of claim 6 , wherein the groove is formed at a distal end of the bracket and the groove is coaxial with the second axis.
8 . A fire suppression system comprising:
at least one source of fire suppression agent; and
a manual activation system coupled to the at least one source of fire suppression agent, the manual activation system comprising:
a bracket rotatable about a first axis between a first configuration and a second configuration;
a pulley movable between an inactive position and an active position, the pulley being mounted concentrically about the bracket and being rotatable about a second axis;
a tension member wrapped about the pulley, the tension member having a tensile force acting on the pulley; and
an activation member configured to cooperate with the bracket to selectively oppose the tensile force;
wherein fire suppression agent is releasable from the at least one source of fire suppression agent in response to a release of tension in the tension member.
9 . The fire suppression system of claim 8 , wherein the bracket includes a groove and the activation member is receivable within the groove when the bracket is in the first configuration.
