JUMPING DEVICE

摘要

A pogo stick-type jumping device includes a lower stanchion on which an upper frame is slidably mounted in a coaxial, generally telescoping relationship. A compression spring connects the upper frame to the lower stanchion and receives the energy required to lift the device off the ground during normal operation. A pair of spark mechanisms is fixedly coupled to the upper frame and is resiliently biased into continuous contact with the lower stanchion. Each spark mechanism includes a wheel assembly that rolls along a length of the lower stanchion and continuously engages a pair of internally-housed flints. Accordingly, in use, displacement of the upper frame relative to the lower stanchion causes the wheel assembly for each spark mechanism to frictionally contact the pair of corresponding flints in such a manner so as to produce an externally visible spark condition that has a visual and/or auditory aesthetic.

1. A jumping device, comprising:
(a) a lower stanchion having an upper end and a lower end; (b) an upper frame slidably mounted on the lower stanchion; (c) a compression spring coupling the lower stanchion to the upper frame; and (d) a first spark mechanism adapted to create a spark condition as the upper frame slidably moves relative to the lower stanchion.
