English: Abstract
An entrapment device is provided for use in a flying disc golf game, or the like, and which provides a structure for absorbing the kinetic energy of flying discs thrown at the device to arrest the forward motion of the discs, and to cause the discs to be caught by the device. The device in one of its embodiments constitutes a post mounted in the ground, a basket mounted on the post, and energy absorbing structure mounted on the post above the basket. When the flying disc is thrown in the direction of the post, so as to strike the energy absorption structure, the energy absorption structure acts as a cushion for the disc thereby arresting its forward motion, and it causes the disc to drop into the basket. |
