PLIWS
PLIWS ( English abbreviation for Play in Wheels = "game on wheels") are 2-roller heel roller skates . In the US they are known as Street Gliders . With this recreational sports device you can both walk and - similar to roller skating - drive.
Layout and function
PLIWS have two rollers each, which can be clamped under the shoes. The TÜV-tested PLIWS are classified as class A heel roller skates, for users with a weight of 20 to 100 kg. You need the smoothest possible surface for gliding because the ground clearance - similar to the Heelys shoes - is relatively small compared to inline skates . They can not only be driven on hall floors, but they are unsuitable for very uneven surfaces such as cobblestones . However, you can walk on such surfaces by lifting your heels and thus preventing the rollers from contacting the ground.
The PLIWS are similar to driving as Heelys, but they sit on the heels of the shoe and are removable. They fit almost every shoe, are adjustable in size and attached to the shoe in just a few seconds.
Similar systems
The so-called skate shoes represent a mixture of Heelys and PLIWS .
Inventor and construction
The inventor of the PLIWS is the Korean Im Geong-Ho. He started production in Korea. The LIGHT-PLIWS were developed in cooperation with the Korean company TELTEK. These are PLIWS with light rollers. The running wheels have a built-in generator ("magnetic battery") which generates the electricity required to operate the light emitting diodes when the wheels are turned. A set consists of two PLIWS.
A set of PLIWS (two heel roller skates) without light consists of:
- 4 plastic parts (they are fixed together with a base plate)
- 4 wheels with 72 mm diameter and Shore A hardness 82A
- 4 axes ( to be fixed with an Allen key )
- 8 ball bearings (2 per wheel)
- 4 Phillips screws for screwing down the base plate
- 2 base plates for screwing on the underside
- 2 rubber bands to fix on the shoe
