JUMP-OVER AMUSEMENT RIDE SUMMARY OF THE INVENTION The present invention is directed to a new and unique type of amusement apparatus whereby a rider seated or otherwise positioned at one end of a long beam is able to vault across the axle of the beam to the other side while passing above the axle at an elevation three to four times as great as the elevation of the axle. This is possible through the employment of an adjustable counterweight on the short end of the beam which passes beneath the axle and is adjustable to a position where the person becomes substantially weightless.

It has been shown by the U.S. Pat. No. 3,298,685 that a counterweight may be used on one end of a centrally supported boom so that a rider on the other end may swing through a 360arc. However in such an apparatus, the elevation reached by the seat is limited, because the distance between the axle and each end must be less than the distance between the axle and the ground. On the other hand, with the apparatus according to the present invention one is able to reach an elevation of approximately 30 feet, although the axle is only approximately feet above the ground. Whereas in the prior art apparatus the beam swings through a 360arc, the beam of the apparatus according to the present invention only swings through a 180 are which considerably increases the elevation of the rider without necessarily increasing the elevation of the axle from the ground.

The apparatus according to the present invention includes a horizontally disposed axle supported at a prescribed distance above the ground on some suitable type of stand or mounting apparatus. A beam is pivotally mounted to the axle at a position off-center, i.e., the beam is supported at a point nearer one end than the other. The shorter end section is of a length less than the distance between the axle and the ground while the longer end section is of a length substantially greater, on the order of twice the distance between the axle and the ground or floor. A seat is pivotally attached to the end of the longer section of the beam in such a manner that as the beam swings over the axle to the opposite side, the seat remains in such a position that the person using the apparatus is always upright.

A counterweight on the order of 1,000 pounds is slidably attached to the shorter end section of the beam and includes some type of moving'means for moving the counterweight toward and away from the axle. The moving means is preferably a hydraulic piston and cylinder which, upon activation, moves the counterweight back and forth. The hydraulic moving means may be operated either by the operator or by the rider himself. As the counterweight moves along the shorter end section of the beam, the operator or the rider can feel the proper position where weightlessness is approximated. The counterweight is then stopped and the apparatus is ready for use.

Some type of hold down means must be provided for securing the longer end of the beam in the nonoperative position during mounting and dismounting of riders. In this regard, in the preferred embodiment, when the counterweight is moved to its innermost position, the downward force exerted by the elements on the longer end section of the beam is greater than the downward force exerted by the counterweight and other elements on the shorter end section, so that the longer end of the beam remains in the down position. Alternatively or in combination therewith, some type of hook and ground attachment could be provided for securing the beam in its nonoperative position.

Additionally, a plurality of beams may be mounted in spaced relation on a single frame so that several riders may occupy the apparatus at one time.

It is therefore an object of the present invention to provide a new and unique type of amusement apparatus wherein a person is made substantially weightless so that he may vault on a beam from one side of an axle to the other and achieve substantial heights in doing so.

Other objects and a fuller understanding of the invention will become apparent after a reading of the detailed description which follows in view of the accompanying drawings wherein:

FIG. 1 is an environmental view showing the apparatus according to the present invention;

FIG. 2 is a perspective view, with the decorative skin removed and parts broken away, illustrating a portion of the framework which supports the present invention;

FIG. 3 is an elevation view of the beam removed from the framework; and

FIG. 4 is a side view of the beam.

Turning now to the drawings, and more specifically to FIG. 1, there is illustrated the present invention which comprises a framework F secured to a trailer T so that the entire apparatus may be moved from place to place. As illustrated in FIG. 1, it should be noted that a plurality of amusement devices are shown on the same frame, however for purposes of clarity, only one of the devices will be described in detail, it being recognized that any number of beams may be mounted along a single axle.

In general, the apparatus includes an axle 10 extending horizontally to and at a position spaced above the ground or a support surface to'which a beam 12 is pivotally attached. Beam 12 is attached to axle 10 at a point spaced from the center thereof, so that there is provided a shorter end section 14 and a longer end section 16. At the end of longer end section 16 a seat 18 is pivotally attached so that a passenger or rider is always in the upright position regardless of the side of the axle on which he may be. A counterweight 20 is adjustsection 14 will freely pass beneath axle 10. On the other hand, the distance between the axle and the free end of the longer end section 16 is considerably greater than the distance between the axle and the ground (on the order of twice as great, so that the longer end section will pass only over the axle and will extend out far enough from the axle when in the horizontal position that a person may easily mount or dismount from the seat 18.)

In FIG. 2 the decorative skin portion of the apparatus has been removed so that the supporting framework is illustrated. The specific construction of the frame which is mounted on the trailer is of no import to the invention, however there are shown a series of angularly disposed channel members which converge toward the top to support an upper series of frame caps 22. Each cap 22 is spaced from the adjacent cap by a distance sufficient to freely support for operation a beam 12 therebetween. A block bearing 24 is secured to the end of each cap 22 and adjacent to the open space between adjacent caps for pivotally receiving the axle or shaft 26 of each beam member therebetween for operation.

A cross member 28 extends transversely to both the axle 26 and to the beam 12 and provides a means for mounting such support rigging as may be necessary to maintain beam 12 and axle 26 in proper relationship. A sleeve 30 is secured to and extends transversely to cross member 28 along the axis of beam 12. Beam 12 is slidably received within sleeve 30 and secured thereto at a point removed from the center thereof as to form the shorter end section 14 and longer end section 16. Once this relationship between the sleeve 30 and the axle 12 is formed, it is not changed.

The outer end of the longer end section 16 of beam 12 terminates in a yoke 36 which includes a pair of

arms

38,40 extending upwardly in bifurcated relation. A seat frame 32 is pivotally attached between the ends of

arms

38,40, there being provided a support axle 34 extending outwardly from each side of seat frame 32 and received within bearings 42 in the ends of

arms

38,40. Thus the seat is pivotally attached to the yoke, so that the riders always remain upright as heretofore described much in the same manner as the seat of a Ferris wheel.

A pair of stop arms 44 extend transversely to longer end section 16 at a point near the end thereof to provide a stop means as the beam approaches the ground or support surface on either side of axle 10. A stop 46 is attached to the free end of each arm 44 by means of a compression stop spring 48 which cushions the impact as the beam 12 approaches the ground. The stop also prevents the riders legs from taking the full jolt of the impact with the ground. The length of arms 44 is such that even though the stop 46 engages the ground before the rider, the rider is still able to reach the ground to push off and begin the arcuate movement of beam 12 when the weightless condition is realized.

The adjustable counterweight 20 includes an opening therethrough by means of which the weight is slidably received along shorter end section 14 of beam 12 and an inner liner or sleeve 21 may be utilized, if desired, to line the opening in weight 20 and engage'the surface of beam 12 to prevent wear on the counterweight material. The bearing 21 may be formed of steel or other suitable material. A pair of guide arms 50 extend forwardly from counterweight 20 toward and through corresponding sleeves 52 which extend through cross member 28 on either side of beam 12. A double acting hydraulic cylinder 54 is suspended from a point near the end of the shorter end section 14 of beam 12 by means of straps 55 for example. The free end of piston 56 is secured in any suitable manner to counterweight 20 so that the counterweight moves back and forth along beam 12 responsive to the action of the hydraulic cylinder 54.

Conduits

58,59 connect the hydraulic cylinder 54 with a fluid reservoir (not shown). The controls 57 for the hydraulic cylinder are suitably attached to the other end of beam 12 near seat '18 so that the rider may control the movement of the counterweight from his seat. Alternatively, an operator can control the movement of the counterweight from his position near where the riders are mounting and dismounting from the apparatus.

It should be noted that it is necessary during mounting and dismounting that the effect of counterweight 20 be overcome when no passenger at all is in seat 18. ldeally, in -the nonoperative position, the cumulative weight of the components on the seat side of axle 10 multiplied by their moment arms (the downward force) exceeds the cumulative weights on the counterweight side of the axle multiplied by their moment arms, so that the seat 18 is always biased toward a non-operative position even when no riders occupy the seat 18. To aid in effecting this balancing effect, as counterweight 20 moves toward cross member 28, the relatively heavy guide rods 50 or a substantial portion of the length thereof move from the counterweight side of axle 10 to the seat side of axle 10, thus giving more weight than is normal on the seat side.

Also, as an added safety feature, if desired, a tiedown arm 60 is pivotally secured at one end to beam 12 and the other or free end is provided with a hook member 62. The tie-down arm is normally biased toward the beam by means of a spring 64 which is fastened between the beam and the tie-down arm. A control cable 66 extends toward seat 18 from tie-down arm and terminates at a control lever 68 which is within the reach of a passenger. A tie-down loop 70 is secured to the ground, to the floor surface, or to a ground anchor, so that as the beam 12 approaches the horizontal position, the operator may position hook 62 within loop 70, thus providing the additional safety feature. When ready to operate, the rider or the operator merely pulls on the release lever 68 which frees hook 62 from the tie-down loop 70 and the apparatus is ready for use.

In operation, assume for purposes of illustration that the beam 12 is in the horizontal or non-operative position ready for a passenger to take a ride. The passenger or passengers mount seat 18 whereupon they are strapped in by the operator by means of holddown straps (not shown). The counterweight 20 is then moved out to a position where the riders appear to be approximately weightless. This position is easily felt by the riders as it is the point where the beam begins to feel like it is balanced. The tie-down 60 is released, and with a spring of the legs, the rider may vault completely across the top of the axle and down to the other sidev Upon reaching the other side, another spring of the legs will return the rider to the initial position. As the rider crosses the axle 10, he is approximately 3 times as high from the ground as the axle is from the ground, which is a completely different type of experience than any apparatus heretofore known. For added thrills, the seat 18 may be locked in a non-pivotal position, so that on the other side of the axle, the rider will actually be coming down head first. There is no danger however, because the stop 46 will prevent the riders head from engaging the ground.

It is obvious that various changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, and in this regard, it is intended that all matters contained in the above-description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
