ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to roller skates and roller blades.
2. Prior Art
Roller skates and roller blades are boots with wheels. A roller skate has four wheels on two axles, and a roller blade has four wheels in a straight line on four axles. Roller skates have 5 cm wheels, and roller blades have 8 cm wheels. Such large wheels lift the users noticeably off the ground and provide sensations which are very different from normal shoes. Novice users are not used to wearing very tall shoes, so they feel unstable and unsafe. This sense of fear discourages many people from trying roller skating or roller blading.
OBJECTS OF THE INVENTION
Accordingly, objects of the present roller wheel slider are:
to enable a user to roll along the ground for recreation;
to add very little height to the user for improved stability;
to be low enough to the ground to give a sense of sliding along the ground;
to provide a sense of safety;
to provide braking capability; and
to be attachable to any shoe.
Further objects of the present invention will become apparent from a consideration of the drawings and ensuing description.
BRIEF SUMMARY OF THE INVENTION
A roller wheel slider is comprised of a mounting plate with clamps on opposite sides for clamping to a shoe. The mounting plate includes a front roller wheel support plate connected to a rear roller wheel support plate by a connecting member. A plurality of axles are mounted transversely under each roller wheel support plate, and a plurality of roller wheels are mounted to each axle. A hard plate on the front end of the mounting plate allows the user to slide when the rear of the shoe is lifted. A resilient friction pad on the rear end of the mounting plate allows the user to brake when the front of the shoe is lifted. The roller wheels are preferably only about 0.5 inch (1.2 cm) in diameter, so that they raise the user by an almost imperceptible amount from the ground to provide a sense of safety, and a sense of sliding along the ground. The large number of roller wheels are distributed across a wide area under the shoe to share the load for durability.
