Rope sway reducing arrangement for weight based hindering of lateral sway of an elongate rope-like means in an elevator hoistway

A rope sway reducing arrangement for hindering a lateral sway of an elongate rope-like device in a hoistway of an elevator system, one end of the rope-like device being attached to a movable component displaceable within the hoistway and another end of the rope-like device being attached to a fixed position within the hoistway, the arrangement comprising:

• an elongate guide arrangement fixedly attached within the hoistway and extending in a longitudinal direction of the hoistway;
• a rope tensioning arrangement including a weight member;
• wherein the rope tensioning arrangement is mechanically connected to the guide arrangement and is displaceable along the longitudinal direction of the guide arrangement and is guided by the guide arrangement;
• wherein the rope tensioning arrangement is mechanically connected to the rope-like device;
• wherein the rope tensioning arrangement generates tensioning forces onto the rope-like device due to gravity-induced forces resulting from a weight of the weight member of the rope tensioning arrangement;
• wherein the guide arrangement includes two spanning ropes extending in parallel in the longitudinal direction between a top portion of the hoistway and a bottom portion of the hoistway;
• wherein the rope tensioning arrangement includes two ring members each enclosing one of the spanning ropes to thereby guide the rope tensioning arrangement along the spanning ropes in the longitudinal direction;
• wherein the rope tensioning arrangement includes an engagement member mechanically connected to the ring members and engaging with the rope-like device to transmit the tensioning forces onto the rope-like device;
• wherein the engagement member engages an upwards directed surface of a lowermost portion of a U-shaped section of a loosely hanging portion of the rope-like device;
• and
• wherein the engagement member is a rope-like connector extending between the ring members.

• wherein the guide arrangement includes at least one spanning rope extending in the longitudinal direction between a top portion of the hoistway and a bottom portion of the hoistway;
• and
• wherein the rope tensioning arrangement includes a ring member enclosing the at least one spanning rope to thereby guide the rope tensioning arrangement along the at least one spanning rope in the longitudinal direction.
