Abstract

The invention provides a pair of walking shoes provided with single row or double rows of rotating rollers. The pair of walking shoes is characterized in that in each walking shoe, the side face of a shoe sole is at least provided with a front hole and a rear hole in a transverse direction; cranks are arranged in the shoe sole; mandrels of the cranks are in clearance fit with the cranks; bearings and the rollers are connected to eccentric shafts of the cranks; torsion, generated as rotating shafts at the ends of the cranks or the rollers, can drive the eccentric shafts or act on the mandrels, and by virtue of transmission devices, the various eccentric shafts are driven and limited to reciprocally rotate between upper axial sections and lower axial sections by an included angle alpha; when the eccentric shafts are tangent to the upper axial sections, the rollers are higher than the lower surface of the shoe sole, so that the shoe is used for walking, and when the eccentric shafts are tangent to the lower axial sections, the rollers are lower than the lower surface of the shoe sole, so that the shoe is used for skating; lifting bolts are also connected to the lower axial sections for regulating and controlling the lower axial sections; the cranks are locked by virtue of locking devices; and a brake is arranged below the shoe sole. The modes of walking and skating can be conveniently and rapidly converted just by lifting feet and controlling in a rotating manner for several seconds; when single row of the rollers are adopted, the walking shoes are high in speed, and when double rows of the rollers, namely four rollers, are loaded, the walking shoes are stable; since the inner sides of the rollers can be greater than the width of the shoes, large-diameter rollers can be adopted, so that the shoes are stable and are slight in vibration; since the faces of the shoe soles are just 2cm away from the ground, the shoes, which roll nearly in a mode of getting contact with the ground, are safe; the shoes are applicable to broad juvenile, youth, adult and middle-aged people in trips and exercises; and the walking shoes can certainly create a new age of human in skating walking.

Description

Single double convolution Roller skate

Technical field

The present invention relates to a kind of can walking stand and can take turns quickly slide and can wink double time of list exchanging of speed Rotation Roller skate.

Background technology

Have in Modern Traffic under aircraft and have car and boat, but go out door in remote mountain villa, on the outskirts of a town, in community, at width In wide campus, on the pavement smooth without the few people of car, without bus subway and other vehicles, changing Before and after Cheng Che in 1,100 meters of short distances of not Portable belt bicycle motorcycle, the mankind can only lean on both feet step by step so far Jogging, wastes time and energy；And the current sports type double boots with straight row of rollers of fitness equipment list, roller skate can only slide with wheel, Can not walking stand, take turns narrow, to be positioned at sole high, crumbling down to make foot plate surface away from ten centimetres of ground for wheel, Only adapt to the teenager's body-building through special training on motion field boundary, but popular forbidding, and inconvenience is at numerous people Middle penetration and promotion；Cruelly walk and when footwear slide, require that user's heel lands, human body can not balance, the weight of crucial whole body Amount concentrates on after pin at root and ankle, easily causes the muscle damage at these positions.

Summary of the invention
