  • a transport system of the continuously-operable, endless type has a succession of interconnected transport vehicles in an endless chain extending to one' or [21] Appl. No.: 77,897
  • References Cited form is shiftable vertically to carry the another level and, possibly, discharge the passengers UNITED STATES PATENTS at this level whereby the vertically shiftable platform can be stopped or slowed angularly to permit such discharge without difficulty.
  • the system has, however, the disadvantage that at some point between the stationary platform andthe main conveyance, the passenger mustbe exposed to some differentialinspeed if he is tobe. accelerated from a stationary condition to the velocity ofthe main conveyance. This is generally accomplished by operating the access conveyor at a rate which is slightly greater than normal walking speed and :less than the main-conveyance velocity also by I an amount equivalent to normal walking speed. Consequently, the passenger is expected to walkrapidly alongside the access conveyor and then step onto the latter so that the transition is effected without irritation, and then is expected to walk along the ,1 access conveyor parallel to the main conveyance to enable him to make the transition between them. Discomfiture and transitional difficulties can be reduced by providing a number of parallel access conveyors of progressively increasing or decreasing speed depending upon whether the access system is to be used for entry to or departure from the main conveyance.
  • the aforedescribed system has some obvious disadvantages. Firstly, there is the limitation on the speed of the main conveyance to a velocity just above the speed of the fastest accessconveyor Secondly, there is the high capital cost of numerousaccess conveyors at each terminal wheneven reasonably high velocities of the maincoriveyance are to be employed. Thirdly, thereis the unavoidable inconvenience of requiring a passenger to stepfroin a slower surface onto a faster surface upon entering the main conveyance or, conversely, requiring thepassenger to step from a faster surface onto a slower surface upon departure.
  • the main conveyance is an endless railway of flexible interconnected vehicles circumscribingthe terminals or access stations, each of the stations being: provided with a plurality of coaxial access platforms of velocities which increase or decrease stepwise-as one moves from one to the other.
  • the disadvantage is that the speed changes at each transitionsothat along theinner periphery of theinnermost access platformythe peripheral speed is sufficiently low to enable the passenger to leave this access platform through a centraldeparture arrangement or to step i upon the slowest access platform from an entry arrangement.
  • Thissystem also has significant limitations, including those enumerated above. Since this system relies upon the relatively small radius of the innerperiphery of the innermost moving platform, to assure a low peripheral speed,-itisdifficultto use the system for mass transport; Furthermore; as the tendency to reduce the transition in speedsbetween the access platforms and betweenthe fastest access platform and the main conveyance increases, there is a corollary requirement that themain conveyance be slowed down or the entry and exit speeds-be increased. In summary, therefore, one

  • a more specific object of the invention is to provide a transport system with an endless main conveyance and a moving-platform terminal which is free from the disadvantages enumerated above, which totally eliminates the difficulties encountered by passengers in entry to or departure from the main conveyance and which generally may operate at relatively low cost and require low capital expenditure.
  • Still another object of this invention is to provide a transport system having a rotary-platform terminal such that the access to the platform is possible over a relatively large periphery.
  • the present invention is based upon a system in which the main conveyance is a continuously moving endless transport arrangement which can con sist of a plurality of flexible linked cars or vehicles, a chain of the conveyor type, and endless band or other continuous and endless means having a support surface upon which the passengers may rest and passing at least at the opposite ends of the system and, if desired, at intermediate locations, around rotary access platforms forming part of terminals, stations or the like.
  • the access means includes a pair of rotatable platforms including an annular intermediate rotating platform about which the main conveyance loops and which operates at an angular speed identical to that of the loop of the main conveyance. While this loop need not extend over a full 360 of the rotary access platform, it has been found to be advantageous to maintain a looping contact over an angle ranging between and 300 as measured about the axis of the rotary platform.
  • An inner rotary platform is provided within the intermediate rotary platform and likewise is rotatable at the aforementioned angular velocity so that, for transfer of passengers between the main conveyance and the intermediate platform, for example, the outer peripheral speed of the intermediate platform is identical to the inner peripheral speed along the loop of the main conveyance and the relative velocity at the transition zone is zero. Similarly, the inner peripheral speed of the intermediate platform and the outer peripheral speed of the inner platform are identical whereby a transition is possible between the intermediate platform at zero relative velocity.
  • the inner platform is shiftable axially, i.e. in the direction of its axis of rotation, relative to the intermediate platform and may be provided with means for varying its angular velocity during axial movement of the inner platform whereby the velocity of the latter can be brought to zero or some other value for a transition to another level.
  • This transition may be at the discharge level of the terminal at which passengers are discharged and/or permitted to enter, in which case the rotary inner turntable is preferably brought to zero angular velocity.
  • another level may be one at which another intermediate rotary platform is provided for a transfer of passengers between one line and another.
  • the inner platform is constituted as a cabin which may be closed along its outer periphery, eg by an axially shiftable cylindrical wall, to enclose the cabin as it is raised or lowered between the effective levels.
  • the inner periphery of the intermediate platform may, of course, also be formed with this safety or protective wall.
  • the passengers may, prior to discharge from the conveyance or entry thereupon, assemble in the region of the peripheries of the endless platforms and the main conveyance without danger so that the rider need not cross the entire width of the terminal for a rapid exit in one short period.
  • a rider may prepare to disembark or enter the transport system, may pass across the intermediate turntable and may position himself upon the inner turntable or platform Without being hurried.
  • Still another advantage of the system of the present invention is to be found in the fact that it automatically changes the vertical position of the passenger as is required in many instances.
  • the main conveyance may be operated at the third storey or the first storey with the discharge level being the second storey.
  • the main conveyance may enter the terminal at the second storey while the cabin or inner platform is vertically shifted from the second to the third or to the first as may be required.
  • the terminal may thus dispense with moving staircases, elevators and like structures hitherto necessary to carry passengers up and down at their destination.
  • a pair of annular partitions is provided along the outer periphery of the vertically shiftable inner platform at the respective levels to close on the one hand the inner periphery on the intermediate platform during shifting of the inner platform and to open the access to the inner platform at the other level.
  • Still another annular partition, likewise vertically shiftable, may be provided around the inner platform and can be movable therewith.
  • the partitions constituting doors for the purposes of the present invention, may be coupled with the vertical movement of the inner platform to afford access and discharge of passengers, depending upon the position of the inner platform.
