Shoe with springs

Abstract

A shoe with springs is disclosed. The shoe includes a sole, two or more fixing plates fixed to the sole, a supporting plate in contact with ground, two or more coil springs mounted between the sole and the supporting plate, and a cover formed in a bellows shape to be folded and unfolded according to contraction and expansion of the coil springs. The cover includes coupling protrusions at an upper end and a lower end. The sole and the supporting plate are formed with coupling grooves along side surfaces, in which the coupling protrusions of the cover are fitted. The coil springs are configured such that a diameter is gradually increased from an upper end portion to a lower end portion. Therefore, the coil springs are shielded by the cover and a coupling structure of the coil springs is improved to prohibit bending of the coil springs in a lateral direction, thereby increasing safety and protecting a user or a bystander from physical damage or injury.

1 . A shoe with springs comprising:
 a sole;   two or more fixing plates fixed to the sole;   a supporting plate in contact with ground;   two or more coil springs mounted between the sole and the supporting plate; and   a cover formed in a bellows shape to be folded and unfolded according to contraction and expansion of the coil springs, the cover including coupling protrusions at an upper end and a lower end,   wherein the sole and the supporting plate are formed with coupling grooves along side surfaces, in which the coupling protrusions of the cover are fitted.   
   
   
       2 . The shoe according to  claim 1 , wherein the coil springs are configured such that a diameter is gradually increased from an upper end portion to a lower end portion. 
   
   
       3 . The shoe according to  claim 1 , wherein the fixing plates and the supporting plate are respectively formed with tunnel-shaped fixing members through which insertion holes are formed in a peripheral direction and a supporting block located near one of the fixing members,
 and wherein upper end portions and lower end portions of the coil springs are inserted through the insertion holes of the fixing members of the fixing plates and the supporting plate, respectively, and upper ends and lower ends of the coil springs are supported by the supporting blocks of the fixing plates and the supporting plate, respectively.   
   
   
       4 . The shoe according to  claim 3 , wherein the fixing plates are formed with slots corresponding to the insertion holes of the fixing members to be communicated with the insertion holes,
 and wherein pressing members which are made of foaming resin are provided to be inserted into the slots.   
   
   
       5 . The shoe according to  claim 3 , wherein the supporting plate includes an upper plate which is formed with the fixing members, and a lower plate which is adhered to the upper plate and formed with a non-slip part,
 and wherein the upper plate of the supporting plate is formed with slots corresponding to the insertion holes of the fixing members to be communicated with the insertion holes, and the lower plate of the supporting plate is formed with pressing protrusions which are inserted into the slots.   
   
   
       6 . A shoe with springs comprising:
 a sole;   two or more fixing plates fixed to the sole;   a supporting plate in contact with ground; and   two or more coil springs mounted between the sole and the supporting plate,   wherein the coil springs are configured such that a diameter is gradually increased from an upper end portion to a lower end portion,   and wherein the upper end portions of the coil springs are fixed to the fixing plates, and the lower end portions of the coil springs are fixed to the supporting plate.
