Brake system for wall arm

An arm system comprising:

• a first arm coupled to a support structure to pivot about a first axis, the first arm having a first portion and a second portion coupled to the first portion for extension and retraction relative to the first portion along a longitudinal axis,
• a patient care equipment support coupled to a distal end of the second portion,
• a first brake positioned within and coupled to both the first and second portions, wherein the first brake is movable between a braking position to impede the longitudinal movement of the second portion relative to the first portion, and a releasing position to allow the longitudinal movement of the second portion relative to the first portion, wherein the first brake is biased to the braking position, and
• a second brake movable between a braking position to impede the pivoting movement of the first arm about the first axis and a releasing position to allow the pivoting movement of the first arm about the first axis, wherein the second brake is normally biased to in the braking position.

An arm system comprising

• a first arm coupled at a first end to a support structure to pivot about a first axis,
• a first patient care equipment support coupled directly to a second end of the first arm to pivot about a second, vertical axis defined along a length of the patient care equipment support,
• a first brake normally biased to a braking position to impede the pivoting movement of the first arm about the first axis, wherein the first brake is movable against the bias to a releasing position to allow the pivoting movement of the first arm about the first axis,
• a second brake normally biased to a braking position to impede the pivoting movement of the patient care equipment support about the second axis, wherein the first brake is movable against the bias to a releasing position to allow the pivoting movement of the patient care equipment support about the second axis.

An arm system comprising:

• a support structure configured to be coupled to one of a ceiling and a wall,
• a first arm having a proximal end coupled to the support structure to pivot about a first axis,
• a first plurality of service delivery lines routed downwardly through the support structure and outwardly through the first arm,
• a second arm having a proximal end coupled to the support structure at a location below the first arm,
• a second plurality of service delivery lines routed upwardly through the support structure and then outwardly through the second arm.
