Controlled trampoline structure

Claim 2

In combination with a bounceable, resilient trampoline net: a. a restraining means to be normally shifted to a first position substantially in engagement with the underneath side of said net to render the same inoperative to prevent its unauthorized use and to be shifted to a second position out of engagement with the net to permit it to be operative and used; b. a shifting means connected to said restraining means to shift the restraining means from the said first position to the second position and to hold the restraining means at the second position; and c. a timer means operably connected to said shifting means to reverse the action of said shifting means to return said restraining meAns to the first said position after the lapse of a selected time interval without interferring with one using said net except rendering said net unable to move in a downward movement.

Claim 3

In combination with a bounceable, resilient trampoline net as defined in claim 1, including a second timer means and a warning signal, said second timer means being correlated with the first said timer means to energize said warning signal and emit a warning signal a short period of time before the first said timer means actuates to reverse said shifting means to move same to said first position.

Claim 4

A gram comprising a bounceable trampoline net connected to a frame member, actuator means closely associated with the trampoline and being operative for alternatively rendering said trampoline net usable and nonusable, control means for operating said actuator means to render said trampoline net usable said control means being operatively connected to said actuator means, electrically operated means for effecting actuating of said actuator means, said control means comprising switch means dominating said electrically operated means, and said switch means being so arranged so that, when said actuator means is actuated, said trampoline net is rendered usable for a predetermined period, said actuator means including a windlass windable and releasable drawstring flexible loop operable means connected to said trampoline net and said frame member for controlling the usable playability of the trampoline net by varying the tension from usage to nonusage conditions on operation of said control means.

Claim 5

A gram comprising a bounceable trampoline net connected to a frame member, actuator means closely associated with the trampoline and being operative for alternatively rendering said trampoline net usable and nonusable, control means for operating said actuator means to render said trampoline net usable said control means being operatively connected to said actuator means, electrically operated means for effecting actuating of said actuator means, said control means comprising switch means dominating said electrically operated means, and said switch means being so arranged so that, when said actuator means is actuated, said trampoline net is rendered usable for a predetermined period, said actuator means including a windlass windable and releasable drawstring flexible loop operable means connected to said trampoline net and said frame member for controlling the usable playability of the trampoline net by varying the tension from usage to nonusage conditions on operation of said control means.

Claim 6

A game comprising a bounceable trampoline net combination as defined in claim 1 and further defined by said actuator means including a pressurized-fluid source and means for connecting the fluid source to said actuator means, and including an operable valve mounted in said fluid source operably connected to said control means.
