Elevator counterweight mounted governor assemblies

An elevator counterweight governor assembly for an elevator assembly, the elevator assembly having a counterweight frame and a fixed member of a hoistway, the counterweight frame defined by a pair of end beams, a header member, a base member, and at least one inner beam positioned between the pair of end beams, each of the pair of end beams and the at least one inner beam are spaced apart and extend in a direction that is parallel with one another extending between and from the header member to the base member in a direction perpendicular to the header member and the base member defining a cavity between the header member, the base member, one of the pair of end beams, and the at least one inner beam, the elevator counterweight governor assembly comprising:

• a swing arm positioned within the cavity and pivotally coupled to the at least one inner beam at one end, the swing arm configured to pivot between a disengaged position and an engaged position;
• a sheave assembly rotatably coupled to the swing arm;
• a flexible elongated member routed through the sheave assembly;
• a braking assembly configured to move between an unactivated state where the braking assembly is free from the fixed member and an activated state where the braking assembly engages with the fixed member to inhibit movement of the counterweight frame,
• wherein, when the swing arm is in the disengaged position, the braking assembly is in the unactivated state and when the swing arm is moved into the engaged position based on a tension on the flexible elongated member, the braking assembly is in the activated state.

An elevator assembly having a hoistway, the elevator assembly comprising:

• a fixed member of the hoistway;
• a counterweight frame having a pair of end beams, a header member, a base member, and at least one inner beam positioned between the pair of end beams, each of the pair of end beams and the at least one inner beam are spaced apart and extend in a direction that is parallel with one another extending between and from the header member to the base member in a direction perpendicular to the header member and the base member defining a cavity between the header member, the base member, one of the pair of end beams, and the at least one inner beam, one of the pair of end beams having a notch portion, the counterweight frame configured to slidably move along the fixed member;
• and
• a counterweight governor assembly comprising:
• a swing arm positioned within the cavity and pivotally coupled to the at least one inner beam at one end and a linkage assembly at an opposite end, the swing arm configured to pivot between a disengaged position and an engaged position;
• a sheave assembly rotatably coupled to the swing arm, the sheave assembly having at least one sheave positioned to extend at least partially into the notch portion of the one of the pair of end beams;
• a flexible elongated member routed through the sheave assembly;
• and
• a braking assembly configured to move between an unactivated state where the braking assembly is free from the fixed member and an activated state where the braking assembly engages with the fixed member to inhibit movement of the counterweight frame,
• wherein, when the swing arm is in the disengaged position, the braking assembly is in the unactivated state and when the swing arm is moved into the engaged position based on a tension on the flexible elongated member, the braking assembly is in the activated state.
