Magnetically-restored steerable roller skate

A steerable roller skate comprising:

• a sole member having a longitudinal axis defined at a central portion thereof and having a pair of rear wheels transversely rotatably secured to a rear bottom portion of said sole member, a steering means having a steering base steerably secured to a front bottom portion of said sole member, a pair of front wheels transversely rotatably secured to the steering base of said steering means by a front axle, a first magnet secured to a central bottom portion of said sole member, and a second magnet secured on said steering base normally positioned under said first magnet, said first and second magnets having opposite magnetic polarities thereof for a mutual magnetic attraction between said first and second magnets for normally restoring the steering base and the front wheels to allow said front axle to be projectively perpendicular to said longitudinal axis of said sole member for a normal straightforward skating of said roller skate;
• the improvement which comprises:
• said second magnet formed as circular shape and including:
• a stem protruding downwardly to be engaged with a stem hole vertically formed in a rear extension portion protruding rearwardly from the steering base, an adjusting screw rotatably mounted in the rear extension portion for fastening the stem of the second magnet on the rear extension portion, and at least a packing washer packed between the second magnet and the rear extension portion to adjust a distance of an aperture as spaced between the first and second magnets, whereby upon disengagement of the screw from the stem of the second magnet, the second magnet will be detached from the rear extension portion for the maintenance thereof, and the position of the second magnet on the rear extension portion may be varied to adjust the aperture between the first and second magnets.
