  • Patent number: 10350502
    Abstract: The multifunctional device has slide and ladder portions easily connectable for use together as a self-supporting unit, and easily detachable for use separately on other equipment or for compact storage or transport. When set-up for use as a self-supporting unit, the ladder and slide portions are hooked together by a double-hook/double-axle connection system that does not allow the angle between the ladder and slide to change any significant amount during normal use of the set-up device. Yet, quick disconnection may be done when the weight of the user is removed, by purposely lifting and pivoting the portions, and then unhooking their top ends from each other. When disconnected from each other, the ladder and/or the slide portion (and preferably both) may be connected/hooked to another object(s), for example, a trampoline or a play equipment platform or other specially-adapted elevated structure, for climbing up to, and sliding down from, said trampoline/platform.
