Track switch for monorails having vertically movable switch segments

A track switch for selectively switching a train from a main track onto a secondary track, each of said main and secondary tracks being substantially T-shaped with a base having two sides and arms having an upper and lower surface, said train having main wheels abutting the upper surface of said arms, up-thrust wheels abutting the lower surface of said arms, guide wheels guided by said two sides of said base and a bogie having all of said wheels mounted thereon, said track switch comprising:

• a turntable operatively coupled to a section of the main track and pivotable between a first position and a second position;
• a first channel;
• a first bridge forming a section of said main track, said first bridge being movable within said first channel between a raised position wherein said first bridge is aligned with said turntable in said first position for passage of the train along said main track and a lowered position wherein said first channel forms a first gap in said main track;
• a second channel;
• a second bridge forming a section of said secondary track, said second bridge being movable within said second channel between a raised position wherein said second bridge is aligned with said turntable in said second position for passage of said train from said main track to said secondary track and a lowered position wherein said second channel forms a second gap between said main track and said secondary track;
• first locking means for locking said first bridge, in said raised position, to said main track;
• second locking means for locking said second bridge, in said raised position, to said main track and said secondary track;
• and
• synchronizing means for synchronously:
• (i) moving one of said bridges to said raised position and simultaneously moving the other of said bridges to said lowered position;
• (ii) locking said raised bridge in position with a corresponding locking means;
• and
• (iii) pivoting said turntable to one of its positions corresponding to said raised bridge, so that a continuous section of track is formed through said track switch for passage of the train.

A track switch for a train for selectively coupling a main track to a selected one of first and second tracks, said track switch comprising:

• first channel means;
• first support means movable within said first channel means between a raised position wherein said first support means forms a first track connection between said main track and said first track and a lowered position wherein the first channel means forms a first gap between said main track and said first track;
• second channel means;
• second support means movable within said second channel means between a lowered position wherein the second channel means forms a second gap between the main track and said second track and a raised position wherein said second channel means forms a second track connection between the main track and said second track;
• control means including
• (i) a linear actuator coupled to each of said first and second support means;
• and
• (ii) synchronizing means for synchronously raising one of said first and second support means and lowering the other of said first and second support means;
• wherein said control means moving one of said first and second support means to said raised position and the other of said first and second support means to said lowered position, so that a continuous section of track is formed through said track switch for passage of the train;
• locking means for locking said first support means in said raised position to said main track and said first track and for locking said second support means in said raised position to said main track and said second track;
• wherein said main track, said first track and said first support means including a first set of lock-receiving means which are aligned when said first support means is in said raised position;
• and said main track, said second track and said second support means including a second set of lock-receiving means which are aligned when said second support means is in said raised position;
• and
• a turntable coupled to said main track and pivotable between a first position, wherein said turntable is aligned with said first support means in said raised position, and a second position wherein said turntable is aligned with said second support means in said raised position.
