Abstract
Description
- This invention relates to a revolving loading platform and in particular to a platform that operates in combination with an endless track conveyor to transport vehicles against the revolving platform for convenient loading.
- The field of revolving loading platforms was rapidly developed during the advance of rail transportation in the late nineteenth and early twentieth century. Revolving loading platforms were proposed for self-propelled or cable operated trains. In general the cars of the trains were mechanically linked to the revolving platform. Because of the size of passenger trains, the revolving loading platform was a complex engineering endeavor and somewhat impractical.
- However, when applied to the smaller scale mechanical ride systems of a modern amusement park, many of the principles and concepts devised for passenger trains are feasible and can be incorporated into a small limited passenger terminal. For example, the amusement ride rail system of Bacon, described in US-A-3,865,041 which corresponds to the precharacterising part of claim 1, utilizes a rotating platform with a deformable peripheral bumper that frictionally engages the side of a passenger vehicle with wheels that engage a stationary arcuate rail to urge or maintain the vehicle against the platform bumper. While suitable for some type of vehicles the complex rail system of Bacon requires special engagement means on the vehicles which may interfere with the preferred means of the conveyance of the vehicle during the ride sequence. For example the floating boats of Bacon incongruously include wheels. Further, the loading system proposed by Bacon is not suitable for certain varieties and configurations of vehicles such as circular, free-floating rafts.
- The amusement ride loading terminal of this invention is primarily devised for use with a circular floating raft. The design of a modern raft ride for an amusement park attempts to duplicate natural settings. The waterway is therefore designed with rapids, twists and turns to simulate a natural river. The raft is free-floating, buoyant and preferably circular to provide all occupants with an equal thrill as the raft freely floats down the water course. In each new run, the raft does not have the same orientation or exact course as in prior runs. To maintain the effect of a substantially unrestrained floatation vehicle, a unique loading terminal was devised.
- According to the present invention, the loading terminal is characterised bythefeatures of claim 1.
- The loading terminal combines a circular revolving passenger platform with an arcuate conveyor, vertically disposed and displaced from the outer edge of the platform. The floatation vehicle or raft floats on a water course to the platform and conveyor where it becomes wedged between them and transported against the platform for a portion of a platform revolution. The outer periphery of the raft is deformable, preferably a pneumatic, annular floatation device. To prevent the circular raft from rolling against the platform the arcuate portion of the conveyor in contact with the raft is operated at a linear speed equal to the equivalent extended diameter of the platform were it at the location of the arcuate contact portion of the conveyor. With respect to the axis of the platform, the platform, raft, and contact portion of the conveyor all have the same angular velocity.
- Passengers wishing to board a raft, first step onto the stationary center of the platform. A passenger wishing to board a raft step onto the revolving platform near the center of the revolving portion of platform where the circumferential speed is small. The passengers therefore steps on a very slow running area with relative safety. Once on the moving platform, they walk outward towards the outer circumference where the rafts are positioned. Atthis point, the speed is high and equal to the speed of the boats. Therefore, the transition from a low entrance speed to the relatively high or normal running speed of the boats is effected safely which is the essence of the rotating circular platform. On boarding, the relative speed of the passenger and raft are essentially the same. The raft is steadied by its frictional engagement with the periphery of the platform and contact segment of the conveyor, yet retains sufficient characteristics of an independent floatation vehicle to impress the boarding passenger with the realistic nature of the impending ride.
- For full utilization of the combination platform and conveyor system devised, other features are includible where the vehicle has specific or limited boarding avenues. For example, where a circular raft has one zone of its periphery dedicated for boarding or egress, this zone must be oriented againstthe revolving platform during the boarding or unloading process. To accomplish this select orientation a short, vertically disposed conveyor segment is independently operated at a speed having an angular equivalent different than the revolving platform. In this manner a roll is deliberately applied to the circular raft to cause it to orient the boarding zone against the platform. Once this orientation is achieved, the conveyor segment is operated at the proper speed to maintain the desired raft orientation as it is transported around with the revolving platform.
- These and other features which contributes to the efficient loading facility of this invention are described in greater detail in the detailed description of the preferred embodiment.

- FIG. 1 is a schematic plan view of the passenger loading terminal of this invention.
- FIG. 2 is an elevational view of the terminal of FIG. 1.
- FIG. is a cross sectional view of the conveyor in FIG. 1.
- FIG. 4 is a cross sectional view of the main conveyor drive mechanism.
- FIG. 5 is an enlarged plan view of the orienting conveyor.
- Referring to FIG. 1 a passenger loading terminal, designated generally by the reference numeral 10 is shown. The loading terminal is particularly designed and constructed for continuous loading of amusement park passengers into independent floatation vehicles or rafts 12 for a simulated river raft ride. A water course 14, of which only a part is shown, begins and. terminates at the terminal.
- At the
termination area 16 of the water course, araft 12 is engaged by aconventional belt conveyor 18 which carries the raft up anincline 20 and over abarrier wall 22 into anupper level waterway 24 where passengers are unloaded and loaded. - Passengers approach the terminal on a
walkway 26 and walk over abridge 28 to astationary center area 30 around which revolves aconcentric platform 32. Theplatform 32 revolves at a relatively slow rate, particularly at the interface with thecenter area 30. Passengers can easily step onto the platform and walk to the outerperipheral edge 34 without any loss of balance. As theouter edge 34 has a linear speed greater than at the interface with thecenter area 30, a plurality of rafts can be efficiently and continuously loaded in rapid succession when moved along with theloading platform 32. - Cooperating with the
platform 32 to move therafts 12 is anarcuate conveyor 36 which is displaced from the outerperipheral edge 34 of theplatform 32. Therafts 12 have an outerpneumatic annulus 40 with an outside diameter greater than the displacement distance between the peripheral edge of the platform and an innerarcuate contact portion 42 of the conveyor. On engagement with theplatform edge 34 andcontact portion 42 the rafts become wedged therebetween and conveyed in conjunction with the revolving platform. The inner arcuate contact portion of theconveyor 36 is operated at a speed equivalent to the extended diameter speed of the platform were it coincident with this portion of the conveyor. In this manner the rafts have the same angular velocity as the platform relative to the rotational axis of the platform and do not roll along theplatforms edge 34. - Where the
rafts 12 are not easily loaded from every orientation, for example, because of the location ofseat backs 44, therafts 12, are selectively oriented by ashort orientation conveyor 46 at the start of their transport in theupper level waterway 24. By operating theorientation conveyor 46 faster or slower than the effective extended diameter velocity of theplatform 32, the raft can be included to roll against the peripheral edge of the platform and be oriented as desired. - Referring to FIG. 2, the
annular platform 32 has a series of inner andouter tracking wheels 48 for supporting the platform onrail 50 mounted on concentric stationary supports 51. Theplatform 32 is rotated around thecenter area 30 by four circumferentially spaced variable speedelectrical drive motors 52 with afriction wheel 54 that engages acircular friction plate 56 on the underside of the platform. A number ofhorizontal guide wheels 55 mounted on the inner edge structure 57 of the rotating platform run against a stationary,circular guide rail 59 embedded in the upper edge of the circularcenter concrete structure 61 as shown in FIG. 2. Thebridge 28 provides an elevated walkway over the platform to allow passengers on the platform to walk or be carried under the bridge without interference. - The
peripheral edge 34 of theplatform 32 has a contact perimeter of vertically mounted wooded slats or continuous steel plates 58 which cooperate with a series of vertically disposal wooden slats 60 on theconveyor 36 to oppositely engage theraft 12 wedged therebetween. - The
raft 12 is fabricated with an outer pneumatic floatation bladder 64, that encompasses aplastic shell 68. Theshell 68 has a plurality of seats 70 for a designated number of passengers, here six. By appropriate rescaling to the terminal particularly the distance between platform and conveyor, larger or smaller rafts can be accommodated. It is naturally understood that the operating mechanisms here described can be applied to vehicles of other configuration or modes of transport, for example wheeled vehicles. - The wooden slats or steel plates on the platform and wood slats on the conveyor provide a suitable contact surface for the pneumatic bladder, compressing the bladder slightly to generate the necessary traction for transport of the raft. The raft is thereby transported by the joint action of both the conveyor and platform. The slats 60 on the arcuate conveyor are mounted to upper and lower drive chains 62 shown in greater detail in FIG. 3.
- Referring to the cross sectional view of FIG. 3, a typical
chain support stanchion 72 is shown. A plurality ofstanchions 72 are uniformly spaced around the length of the arcuate conveyor for support of curved upper and lower guide channels, 74 and 76, and, thecontact portion 78 and return portion 80 of the movingconveyor track 82. - The
stanchion 72 is constructed with abase plate 84 for mounting the stanchion to the bed of theupper waterway 24. Thebase plate 84 has avertical post 88 mounted thereto which supports upper andlower cross brackets guide channels 74 and 76 are attached. The guide channels are fabricated from sections of elongated curved L-beams, 94 and 96, which are welded together at their ends to provide the continuous arcuate conveyor configuration shown in FIG. 1. The inner and outer L-beams, 94 and 96, are jointly bolted to thecross brackets bolts 98. - The moving
conveyor track 82 is constructed with anupper link chain 100 that is arranged within the upper guide channel 74 and alower link chain 102, that is arranged within thelower guide channel 76.Chain 102 is transported on a low friction slide bearing 104 attached to thelower guide channel 76 byanchor bolts 106. The upper and lower link chains are interconnected by the vertical wooden slats 60 which are bolted bycarriage bolts 108 toangle iron brackets 110 that connect to the journal pins 112 of thelink chain rollers 114. In this manner the displacement of the upper andlower link chains - As schematically illustrated in FIG. 1, each end of the
conveyor 36 includes asprocket mechanism 122 to reverse the direction of the movingtrack 82. One end, for example the raft entry end, has adrive motor 142 connected to thesprocket mechanism 122. The sprocket mechanism including the drive motor is shown in FIG. 4. Asocket 124 is mounted to thebed 86 of theupper waterway 24. Asupport post 126 is inserted in the socket and, for the main conveyor, is secured from rotation in the socket by aset screw 128. Thesupport post 126 has twohorizontal support arms 130 connected to a journal casing 132 in which ajournal 134 is vertically mounted. The journal has asprocket 136 at each end which engages the upper and lower link chains, 100 and 102. Extending from the journal at the top sprocket is adrive spindle 138 which is keyed to therotor 140 of the variable speedelectric motor 142. Themotor 142 is supported on a bracket 144 connected to atop mounting plate 146 on thesupport post 126 by ashock mount 148. - Operation of the
drive motor 142 for the conveyor is regulated by conventional control systems to coordinate conveyor speed with the speed of thecontact portion 78 of the revolving platform to prevent roll of the rafts along the conveyor and platform. Thus, when platform rotation speed is increased or reduced according to passenger demand the conveyor speed is accordingly adjusted. By increasing or decreasing the speed of the conveyor relative to the equivalent angular speed of the platform, engaged vehicles will roll against the platform and reorient themselves for convenient loading or unloading. Preferably the orientation is accomplished by a separate mechanism described hereafter. - The
short orientation conveyor 46 includes asprocket mechanism 122 at each similar to that shown in FIG. 4. As illustrated in FIG. 5, theorientation conveyor 46 includes a hydraulic orpneumatic activation mechanism 150 mounted at one end to thebed 86 of theupper waterway 24 and at the other end to theconveyor 46 to pivot the conveyor46 about the axis of thesupport post 152. In this manner the conveyor can be swung across the waterway to shunt selected rafts into aspur waterway 154 for removal from service. In such a system, thesprocket mechanism 122 at the swinging end is not supported in a socket but includes a support roller at its bottom end (not shown). Thesupport post 152 at the pivotal end is 149a and 149b of an interconnectingsupport structure 151, is not pinned by a set screw to its support socket, but is free to pivot therein. - In a usual situation the
orientation conveyor 46 is employed to roll the raft by a differential in the effective angular speed of the conveyor relative to the platform by variations in the speed of a variable speed drive motor 153. Theorientation conveyor 46 has a vertically disposed conveyingsurface 155 with a contact portion 157 displaced from the peripheral edge orcircular periphery 34 of the platform. Araft 12 becomes engaged between the orientation conveyor and the platform and is rotated by an effective differential arcuate speed between the contact portion 157 of theconveyor 46 and theperiphery 34 of the platform produced by a variablespeed drive motor 159. Generally, theconveyor 46 is slowed or stopped until a strategically mounteddetectable plate 156 is detected adjacent the platform by an elongated bed-mounted, sensor plate 158. When detected the appropriated compatible speed of the orientation conveyor to the platform is resumed, thus maintaining the selected proper positioning of the raft for unloading and loading.
