Abstract
Abstract An amusement device having a curved-loop, slide element causing the rider thereof to undergo a portion of his travel in the inverted position. The slide is tubular with a generally circular cross sectional wall, and at least the upper portion of the cross sectional wall may be transparent. The upper inlet end of the slide may have an air blower to assist in maintaining the speed of the user. Downstream of the loop is a decelleration section.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
62 words
A slideway amusement device for conveying a person in a sitting posture from a first position to a second position by low-friction, sliding contact with said device comprising an acceleration element having a smooth sliding-contact surface, at least one tubular, vertical looping element substantially circular in cross-section and having a smooth sliding-contact surface, and a deceleration element having a smooth sliding-contact surface.
Claim 2
Dependent Claim
62 words
A slideway amusement device for conveying a person in a sitting posture from a first position to a second position by low-friction, sliding contact with said device comprising an acceleration element having a smooth sliding-contact surface, at least one tubular, vertical looping element substantially circular in cross-section and having a smooth sliding-contact surface, and a deceleration element having a smooth sliding-contact surface.
Claim 3
Dependent Claim
105 words
An amusement device as in claim 1 wherein the acceleration element is comprised of a substantially linear tube with a first opening at a first elevation and a second opening at a second elevation, and the loop element is comprised of a tube forming a single loop having an entrance opening at said second elevation in alignment with said second opening and an exit opening at a third elevation, said second elevation being sufficiently lower than said first elevation to permit acceleration of a person to a velocity sufficient to cause continued contact of the person with the outermost inside surface of the loop element.
Claim 4
Dependent Claim
69 words
An amusement device as in claim 2 wherein the deceleration element is comprised of a member having a terminal opening at a fourth elevation and a further opening at said third elevation in alignment with said exit opening of the loop element, the relative elevations of the third and fourth elevations being such as to permit deceleration of the person to approximately zero velocity upon reaching said terminal opening.
Claim 5
Dependent Claim
25 words
An amusement device as in claim 3 wherein the acceleration element, the loop element and the deceleration element are substantially fabricated from a transparent material.
Claim 6
Dependent Claim
30 words
An amusement device as in claim 3 wherein the elements are fabricated from a metallic material in the lower portion thereof and a clear material in the upper portion thereof.
Claim 7
Dependent Claim
24 words
An amusement device as in claim 5 wherein the elements are comprised of segmented sections having means for joining one section to the next.
Claim 8
Dependent Claim
57 words
An amusement device as in claim 1 wherein the acceleration element is comprised of a tubular member and air pressurizing means whereby the person is accelerated to a velocity such that during passage through the tubular looping element centrifugal forces exist to cause continued contact of the person with the outermost inside surface of the loop element.
Claim 9
Dependent Claim
40 words
An amusement device as in claim 7 wherein the deceleration element constitutes a tubular element with a coefficient of friction and a horizontal angle such that it will bring the person to a stopped condition upon reaching said second position.
