Title: Sole of ergonomic shoe suiting human foot structure and walking
Inventor: PARK MOON HWAN
IPC: A43B13/14
Filed: 2007-03-13
Abstract: This invention relates to a highly engineered shoe sole developed to fit the natural structure of the human foot and walking gait. By inventing a shoe sole with the heightened outer part of the shoe heels and lowered on the inner part of the front portion of the sole, the shoe enables the triple-time stepping by maintaining his/her feet and the ankle aligned with the shoes when standing or walking. Also, by naturally shifting the center of the body inwards from the outer part of the shoes, thus distributing the body weight evenly to the entire area of the shoe soles, the shoes reduce fatigue on the foot by absorbing and mitigating the impact on the foot that supports the body weight, which prevents and corrects deformed walking habits such as out-toed gaits and also prevents slipping while walking.

Title: High-speed unicycle including six gears
Inventor: KWON SUN-U
IPC: B62K1/00
Filed: 2010-12-14
Abstract: The present device relates to a speed-up gear for increasing the speed of a unicycle. That is, three gears (e.g., widely-used spur gears) are provided as one set, and two sets of spur gears are symmetrically attached to both the left and right sides of the unicycle to increase the speed of the unicycle. A large gear (1) of the three right gears is coupled to a pedal crank (19). An intermediate gear (2) of the three right gears changes a rotation direction. A small gear (3) of the three right gears is coupled to a wheel shaft to increase the speed of a unicycle in proportion to a ratio of the diameter of the large gear (1) to the diameter of the small gear (3). The three left gears are attached at symmetrical positions with respect to the three right gears except that only a left pedal crank is coupled in a direction which is rotated at an angle of about 180 degrees with respect to the right pedal crank (19). The aim of the present invention is to provide a unicycle in which a speed-up gear can be attached to a typical unicycle which does not have a large wheel, so as to achieve a high speed. Thus, short people can ride the unicycle, people riding the unicycle can be safe when the unicycle falls, and the unicycle can be easily loaded onto a vehicle. Figure 3 illustrates an assembled structure of the three gears of the unicycle, wherein the intermediate gear (2) has a small size and the position of a pedal crankshaft is lowered.
