TRAILER MOUNTED COLLAPSIBLE ROUNDABOUT The present invention relates to an amusement ride, or roundabout, and is particularly concerned with an amusement ride which is trailer mounted and which can quickly be erected for use or collapsed for transport.
Amusement rides are known and are widely employed and quite often are of a type that can be transported from place to place. When the amusement ride is constructed so as to be transportable. it is extremely important to be able to erect the ride into operative position and to collapse the ride for transport in the shortest possible time and with the employment of as little labor as possible.
The amusement ride must, however, be extremely strong so as to be free of hazards of accidental collapse and tilting. and the like.
With the foregoing in mind, the primary objective of the present invention is the provision of an amusement ride which is mounted on a trailer bed and which can be erected and collapsed quickly and with a minimum of labor.
Another objective of the present invention is the provision of an amusement ride of a novel type which is readily moveable from place to place.
BRIEF SUMMARY OF THE INVENTION:
According to the present invention, a trailer bed is provided of the type in which the portion between the rear wheels and the point of connection to a towing vehicle is at the lowest practical height from the road. Such trailer are known, being referred to as flat bed trailers. and are employed for transporting objects having substantial height.
Carried on the trailer bed is a platform which is swing-ably connected to the trailer bed by frame members spaced longitudinally of the trailer bed so that the platform can be raised in substantial parallelism with itself from a lower position to an elevated working position.
When in working position, the platform is locked to the trailer bed by a third frame member so that the platform is rigidly supported in its elevated position. Rotatably connected to the platform in about the middle of its length is an elongated beam with drive means for the beam being provided on the platform.
At the outer ends of the beam there are suspended groups. or clusters. of passenger compartments which are tiltable on the beam and which are also rotatable about a respective axis of the group substantially perpendicular to the beam. Drive means are provided on the beam at the ends for rotating the groups of passenger compartments about the respective axes of the groups.
When the platform is in elevated operative position, outriggers pivoted to the sides of the trailer are placed in outward bracing position and support members at the front and rear ends of the trailers are adjusted into engagement with the surface beneath the trailer and, thus. an extremely rigid support is provided for the platform and arm. The platform supporting the beam is advantageously braced on the extended Outriggers.
The exact nature of the present invention will become more apparent upon reference to the following detailed specification taken in connection with the accompanying drawings. in which:
FIG. 1 is a side elevational view of the amusement ride according to the present invention in erected position.
FIG. 2 is a side elevational view of the amusement ride in collapsed transport position.

DETAILED DESCRIPTION OF THE INVENTION:
Referring to the drawings somewhat more in detail, FIGS. I and 2, showing a flat bed trailer arrangement 10 having a frame 11 with ground wheels 12 at the rear end and a coupling device 14 at the forward end for connection of the trailer to a towing vehicle.
Vertically retractable pads are provided on the trailer for fixedly supporting the trailer when the ride is to be put in use. These pads comprise pads 16 near the front of the trailer and I8 at the rear of the trailer. The pads are, of course, along both sides of the trailer. Further. the trailer bed is provided with outrigger arms 20 which can be swung outwardly at the sides of the trailer and which, in turn, comprise ground engageable pads 22.
In FIG. 1, the outrigger arms 20 are shown in outer supporting position, and in FIG. 2 the outrigger arms 20 are shown collapsed inwardly against the sides of the trailer frame. For purposes of further stability, the forward end of the trailer may have a cavity which is weighted as by concrete 24 poured into the cavity.
A ride support platform 26 is provided which at the rearward end has pivotally connected thereto as at 28, the upper end of a support frame member 30, the lower end of which is pivoted at 32 to the trailer frame. A further frame member 34 is pivoted on pivot axis 36 to the forward end of platform 26 with the lower end of the frame member 34 being pivoted at 38 to the trailer frame.
The frame members 30 and 34, as will be seen in FIG. 1, are not parallel and will support the platform 26 in elevated position so that the platform inclines downwardly toward the rear of the trailer. When platform 26 is collapsed downwardly on the trailer bed, however, members 30 and 34 hold the platform substantially parallel to the longitudinal axis of the trailer and frame.
Also pivoted to the support platform 26 on the forward pivot axis 36 is a further frame member 40, the lower end of which is adapted for connection to the trailer frame as by the bracket means. generally indicated at 42.
The bracket means, generally indicated at 42, is illustrated in detail in FIG. 10. In FIG. 10, the bracket means will be seen to comprise a pair of spaced plates 44 fixedly connected to the longitudinal members 46 of frame 11 of trailer and formed with apertures 48 for receiving a pin 50 and also formed with notches 52 in the forwardly facing edges.
Frame member 40, of which one side is shown in FIG. 10, has extending therefrom a pair of plates 54, each of which is supplied with an aperture 56 and through which plates there extends a pin 58.
When the platform 26 is in its FIG. 2 collapsed position, frame member extends forwardly therefrom along the trailer bed. When the platform is raised upwardly to working position, however, the leftward end of frame member 40 slides along the trailer bed and pin 58 will enter notches 52 of plates 44 and thereby halt platform 26 in the proper elevated position and whereupon lock pin can be inserted through apertures 48 and 56 and thereby lock the platform in its elevated position.
FIG. 1 1 shows the platform in elevated position from the left side and shows that a telescoping hydraulic cylinder arrangement 60 is provided for raising and lowering platform 26 and having the lower end pivoted at 62 to the trailer bed and having its free end pivoted at 64 to the underneath side of platform 26 near the rearward end thereof.
FIG. 1 1 will also show the frame members 30 and 34. It will be seen that each of these frame members comprise parallel side rails rigidly interconnected by diagonal bracing and the like. The frame members are advantageously formed of tubing for the greatest strength and lightest weight.
Pivotally supported on the upper side of platform 26, as by suitable bearing means, is an elongated beam member 70. Fixedly mounted on the upper side of platform 26 is a sprocket 72 and mounted on beam is a drive motor 74 which has a geared down output shaft on which a sprocket 76 is mounted, which is coplanar with sprocket 72. A chain 78 is entrained about the sprockets and, thus, when motor 74 is energized, the beam 70 will be caused to rotate about the axis 80 on which it is pivotally supported.
Motor 74 is preferably an electric motor and power is supplied thereto by any suitable slip ring arrangement from a power source external of the amusement ride arrangment. The beam 70 is preferably a box-like member for high strength and light weight and at each end has a portion 82 which is bent upwardly from the axis of the center portion 84 of the beam, at an angle of about 20 degrees. The amount which the,end portions 82 of the beam are bent upwardly from center portion 84 thereof is such that the one of portions 82 which is lowermost when beam 70 is in a fore and aft position on the trailer is substantially horizontal and thereby presents the passenger compartments supported thereon in loading position.
Near the outer end of each of the bent up portions 82 of the beam, there is rotatably supported a structure, generally indicated at 86, and each of which is rotatable on a respective axis 88 on the beam 70. For rotating the structure 86, the beam 70 has at each end a motor 90 with a geared down output shaft on which a friction member 92 which may be a pneumatic vehicle tire, is mounted and which frictionally engages a cylindrical portion 94 of the adjacent rotary structure 86.
Each rotary structure 86 and which can be best seen in FIGS. 3 through 7, comprises a plurality of, say six, radiating arms. Five of the arms comprise radially inner portions fixedly connected to the rotary structure and projecting radially therefrom to a joint structure 102. Each joint structure 102 is constructed, as will be seen in FIGS. 4 and 5, of plate members 104 and 106 connected to the top and bottom of the respective arm portions and in overlapping relation. The plates 104 and 106 have registering apertures adapted for receiving pins 108. When the arm portions consisting of the radially inner portion 100 and the radially outer portion 110 are placed together and the pins 108 put in place, each arm structure will be rigidly supported on the respective rotary structure 86.
One of the radially inner portions 100 at each end of the main arm 70 is pivotally connected to the rotary structure 86 by a separable connector or pivot means, generally indicated at 112, and shown at enlarged scale in FIGS. 6 and 7. Each of the arrangements 112 comprises a bracket 114 fixedly welded to the rotary memher and having plates I15 fixed to the sides thereof.
The respective radially inner portion of the pertaining passenger compartment support arm has plates 1 16 on the opposed sides which overlap plate 115. Holes provided in the plates receive pins 118.
As will be seen in FIG. 2 at the rearward end of the main beam 70, the respective passenger compartment support arm is merely pivoted backwardly beneath main beam 70 for transporting of the device, whereas at the forward end the pertaining passenger compartment support arm is removed from the assembly. In each case, the passenger compartment support arm directly opposite the arrangement 112 can be rigid since this particular passenger compartment support arm is directed toward the center of the vehicle and creates no problems when the ride is collapsed and is being transported.
As will be seen in FIG. 3, the rearward arm is provided with a connector or pivot 112 so that it can either be pivoted backwardly underneath the main beam or dismantled completely therefrom while the passenger compartment support arm diametrally opposed thereto can be rigid and remain in assembled position. The four passenger compartment support arms extending laterally are adapted for being separated at joint 102 thereby to fall substantially within the lateral limits of the bed of trailer 10.
When the passenger compartment support arms are erected lateral bracing elements are connected therebetween to make up a substantial rigid structure.
FIGSv 8 and 9 show how the passenger compartments are supported on the outer ends of the respective radially outcr portions 110 of the passenger compartment support arms. Each radially outer portion 110 has a square member in the form of a tube 122 therein and extending coaxially therethrough in a rotated position is another square member 124 of smaller size. Nested into the inside of each corner of larger tube 122 and bearing against the opposed side of inner tube 124 is a rubber like resilient member 126. Connected to inner square member 124 is a dependant bracket I28 and fixedly secured thereto and dependant therefrom is a further bracket I30. Extending between the opposed legs of bracket is a smaller square member 132, the
axis of which is at right angles to the axis of square members 122 and 124 above referred to.
Surrounding square member 132 is a square tube 134 of larger size and. as will be seen in FIG. 9. resilient blocks 136 are provided which are nested into the corners of tube 134 and which bear against the opposed flat sides of square member 132. Fixed to the larger tube 134 and dependant therefrom is a rod 138 which may be in the form of a tube and at the lower end of each rod 138 there is fixedly connected a respective passenger compartment 140.
The arrangement of the telescoping square tubular members of different size with the rubber-like blocks interposed therebetween provides for efficient swinging support of the passenger compartments on the respective support arms, while at the same time the support is resilient and the movement of the passenger compartments is thereby controlled so that the amount of swinging of the passenger compartments on the respective support arms is relatively free while being r'esiliently opposed by an ever increasing'restoring force.
The sensation of substantially free motion is thereby obtained when the ride is operated; while at the'same time no dangerous conditions are established because of the restoring forces established by the resilient blocks I26 and 136 when the passenger compartments swing away from the rest position thereof. which they are shown at the right side of FIG. 1.
One or the other of brackets 128 and 130 may be separable and secured together by bolts 142. as shown in FIGS. 8 and 9. The separability of a bracket permits the passenger compartments to be removed from the support arms therefor when the ride is to be collapsed.
As mentioned. brace rods l44 .can be connected in substantially vertical positions between the sides of the platform 26 and the outrigger arms 'when the platform is elevated. The bracerods 144 are. of course, removed for collapsing the ride into transport position.
To collapse the ride. the passenger compartments are removed and may be stored in a compartment 146 at the rear end of the trailer bed. The passenger compart ment support arms arethen adjusted into transport position and the brace rods 144 are removed. Motor 60 is then energized to support the weight of the ride and lock pins 50 are removed. The fluid can now be re leased from fluid motor 60 at a controlled rate and the platform 26 will pivot downwardly to transport position with the lower end of support frame member sliding forwardly along the trailer bed.
With respect to adjustment of the support arms for the passenger compartments into transport position. reference may be had to FIG. 3 which shows the rotary passenger compartment supporting structure at the rear end of the trailer. When the structure is broken down for transport. brace elements 120 are removed. and the radially outer sections 1 l0 pertaining to the lat erally extending support arms are removed. while the rearwardly extending support arm is hinged downwardly by hinge means I 12 so as to lie underneath main beam 70. The support arm extending to the left can remain in position beneath beam 70 as it is shown in FIG. 2.
At the front end of the trailer. the same adjustments are made except that the passenger support arm which extends forwardly is completely removed rather than being folded under beam 70.
Beam is. of course, in a fore and aft position and when the ride is fully collapsed is secured fixedly to the trailer bed. The support pads 16 and 18 can now be retracted and the outrigger arms 20 moved to retracted position andthe ride is ready for transporting.
FIG. 1 shows a decorative superstructure arrangement I50 and it will be understood that this superstructure is preferably dismantled for transport to reduce the heighth of the collapsed ride. The various electrical connections, and the like, within the ride structure can be made in a conventional manner.
For the purpose of keeping the structure light, as well as strong. tubular steel members are employed where ever possible. for example. in connection with the frame memberswhich support platform 26 and in connection with the passenger compartment support arms. For protecting the tubular members against rust and corrosion. and to prevent damage thereto by deformation of the end parts during assembling and disassembling of the ride. each such tubular member is provided at the ends with welded in closure caps. A typical closure'cap of this nature is illustrated at 150 in FIGS. 8 and 9, for example.
The device illustrated makes reference to removal of the carriages. or cabs. for storage in a compartment mounted on the rear end of the trailer vehicle. However. it is also contemplated to dispose the cabs along the sides of the main beam for transport. The seats can be arranged in side by side relation along the main beam and the seat arms could extend over the main beam. The overall height of the collapsed ride would not be materially increased in this manner and no problems will be encountered in connection with transporting the ride.
The drawings illustrate the main beam as being rotated by a chain drive. while the devices at the ends of the main beam supporting the passenger cabs. or seats. are shown as being rotated as by friction drive. It will beunderstood that all of the drives could be friction drives. if desired. or all thereof could be chain drives. or any combination of friction and chain drives could be employed.
Modifications may be made. within the scope of the appended claims.
