Abstract
A switch for a cable transportation system has a movable guide with one degree of freedom, along an operating plane, between two designated or given positions; and an actuating assembly having a rotary actuator, and a crank which is rotated by the rotary actuator between two limit stops about an axis of rotation perpendicular to the operating plane, and is connected to the movable guide in such a manner as to define a mechanism having two stable positions corresponding to the designated or given positions of the movable guide when the crank is in the limit stop positions.
Claims30
A cable transportation system switch comprising:
- a movable guide movable, along an operating plane, from a first designated position to a second designated position and from the second designated position to the first designated position;
- and
- an actuating assembly including:
- a rotary actuator, and
- a crank configured to be rotated by the rotary actuator about an axis of rotation transverse to the operating plane, said crank configured to be rotated from a first limit stop position to a second limit stop position and from the second limit stop position to the first limit stop position, and said crank being connected to the movable guide to define a mechanism having:
- (i) a first stable position corresponding to the first designated position of the movable guide when the crank is in the first limit stop position beyond a top dead centre position of the mechanism, and (ii) a second stable position corresponding to the second designated position of the movable guide when the crank is in the second limit stop position beyond a bottom dead centre position of the mechanism.

A cable transportation system switch comprising:
- a rotary actuator;
- a crank configured to be rotated by the rotary actuator about an axis of rotation transverse to an operating plane of a movable guide, said crank connected to the movable guide by a pin housed slidably inside a slot in the movable guide, and said crank configured to be moved to each of a first stable position defined by a first end of the slot in the movable guide and a second stable position defined by a second end of the slot in the movable guide;
- and
- a connecting rod hinged to the crank and the movable guide, wherein:
- (i) when the crank moves to the first stable position, the connecting rod pivots to cause the movable guide to move to a first designated position, and (ii) when the crank moves to the second stable position, the connecting rod pivots to cause the movable guide to move to a second designated position.

A cable transportation system switch comprising:
- a movable guide movable, along an operating plane, from a first designated position to a second designated position and from the second designated position to the first designated position;
- and
- an actuating assembly including:
- a rotary actuator, and
- a crank connected to the movable guide by a pin housed slidably inside a slot in the movable guide, said crank configured to be rotated by the rotary actuator about an axis of rotation transverse to the operating plane, said crank configured to be rotated from a first limit stop position defined by a first end of the slot in the movable guide to a second limit stop position defined by a second end of the slot in the movable guide and from the second limit stop position to the first limit stop position, and said crank being connected to the movable guide to define a mechanism having:
- (i) a first stable position corresponding to the first designated position of the movable guide when the crank is in the first limit stop position, and (ii) a second stable position corresponding to the second designated position of the movable guide when the crank is in the second limit stop position.
3 more elements
A cable transportation system switch comprising:
- a movable guide movable, along an operating plane, from a first designated position to a second designated position and from the second designated position to the first designated position;
- and
- an actuating assembly including:
- a rotary actuator,
- a crank configured to be rotated by the rotary actuator about an axis of rotation transverse to the operating plane, said crank configured to be rotated from a first limit stop position to a second limit stop position and from the second limit stop position to the first limit stop position, the limit stop positions being defined by a fixed catch, and two seats defined by the crank which alternatively engage the fixed catch, and said crank being connected to the movable guide to define a mechanism having:
- (i) a first stable position corresponding to the first designated position of the movable guide when the crank is in the first limit stop position, and (ii) a second stable position corresponding to the second designated position of the movable guide when the crank is in the second limit stop position, and
- a connecting rod hinged to the crank, and the movable guide.
4 more elements
A cable transportation system switch comprising:
- a movable guide movable, along an operating plane, from a first designated position to a second designated position and from the second designated position to the first designated position;
- a first actuating assembly including:
- a first rotary actuator, and
- a first crank configured to be rotated by the first rotary actuator about an axis of rotation transverse to the operating plane, said first crank configured to be rotated from a first limit stop position to a second limit stop position and from the second limit stop position to the first limit stop position, and said first crank being connected to the movable guide to define a first mechanism having:
- (i) a first stable position corresponding to the first designated position of the movable guide when the first crank is in the first limit stop position, and (ii) a second stable position corresponding to the second designated position of the movable guide when the first crank is in the second limit stop position;
- a second actuating assembly;
- two first movable guides, each first movable guide movable between two designated positions along the operating plane;
- and
- two second movable guides connected rigidly to each other and which rotate, about an axis of rotation, along the operating plane between two designated positions.
