Abstract

Abstract A novelty or game device which includes a pair of magnets provided with relative movement whereby the movement may be caused to stop should the magnets be brought into sufficiently close proximity to each other to be mutually attracted thereby. One magnet is immovably mounted on an upright support member, and a second magnet is mounted on the free swinging end of an elongated manually manipulatable support arm. The opposite end of the support arm is pivoted to a second upright support member spaced from the first support member. As the support arm is swung about the second upright support member, the magnet on the free end thereof is swung in a defined circle into sufficiently close proximity to the fixed magnet whereby the two magnets may mutually attract each other and stop the swinging magnet only if it is travelling at a sufficiently slow rate of speed.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 168 words
A novelty device comprising: a generally U-shaped support structure having first and second upstanding leg portions; first magnetic means mounted in an elevated position on said first leg portion; a generally rigid elongated support arm rotatably mounted at one end to said second leg portion so that said support arm is swingable through the air relative to said second leg portion between said leg portions; and second magnetic means attractable by said first magnetic means and mounted on the free swinging end of said support arm, the free end of said support arm defining a path of travel for said second magnetic means, one portion of said path of travel being sufficiently close to the first magnetic means so that said first and second magnetic means attract one another, whereby the magnetic attraction between said first and second magnetic means can stop the rotation of the support arm and the second magnetic means thereon when said second magnetic means is travelling at a sufficiently slow rate of speed.
Claim 2
Dependent Claim 168 words
A novelty device comprising: a generally U-shaped support structure having first and second upstanding leg portions; first magnetic means mounted in an elevated position on said first leg portion; a generally rigid elongated support arm rotatably mounted at one end to said second leg portion so that said support arm is swingable through the air relative to said second leg portion between said leg portions; and second magnetic means attractable by said first magnetic means and mounted on the free swinging end of said support arm, the free end of said support arm defining a path of travel for said second magnetic means, one portion of said path of travel being sufficiently close to the first magnetic means so that said first and second magnetic means attract one another, whereby the magnetic attraction between said first and second magnetic means can stop the rotation of the support arm and the second magnetic means thereon when said second magnetic means is travelling at a sufficiently slow rate of speed.
Claim 3
Dependent Claim 21 words
The novelty device of claim 1 wherein said support arm may be swung a full 360* about said second leg portion.
Claim 4
Dependent Claim 25 words
The novelty device of claim 1 wherein said first magnetic means is mounted above the mounting between the support arm and said second leg portion.
