Variable ratio control shoe with automatic tying and untying shoelace

A variable ratio control shoe with automatic tying and untying of shoelaces, including a shoe body and at least one tying component, a modulated variable ratio multiplex mechanism, a control mechanism, and having an adjustment mechanism to perform self adjustment of tension, and comprising:

• (a) a shoe body including two tying earpieces of a vamp, a first tying earpiece corresponding to an end of a tying component and being laminated to form the adjustment mechanism, a second tying earpiece having an inside lamination in combination with an eyelet and at least one laminated cord accommodating channel communicating with the modulated variable ratio multiplex mechanism assembled between a middle sole and a shoe pad, an extended end of the shoelace and tying component extending from the cord accommodating channel into the shoe body to connect with the modulated variable ratio multiplex mechanism as its drive, a rear of an outsole having a control mechanism;
• (b) a tying component, comprising a decorative shoelace and a shoelace cord intertwined, a fixed end of said shoelace cord inserted in the second earpiece inside lamination, to adjust a tying tension, an extended control end of the shoelace cord extending from the laminated cord accommodating channel into the shoe body, to the variable ratio multiplex mechanism;
• (c) a variable ratio multiplex mechanism installed between the shoe pad and the middle sole of the shoe body, and including:
• a modulated sole lamination, assembled between the middle sole and the shoe pad, an end face of the modulated sole lamination having at least one assembling space groove, a cord guide block installed adjacent to and communicating with a moving space, at rear inside the space groove having rows of support posts, slide members and tying spots;
• a pressing plate, connected to the assembling space groove of the modulated sole lamination, at a bottom of the pressing plate and a rear of a curve arm is pressed an insert member with an end formed as a snap head, the pressing plate being pressed by a user's foot, through an open hole aligned with the hollow channel of the sole lamination and middle sole, and engaged by the control mechanism inside the control groove of the outsole;
• the curve arm, installed at a position aligned to the pressing plate inside the assembling space groove, normally pressed by a flexible member to be curved up, a slide end of the curve arm inserted on a pulling plate, a slide member of the pulling plate working with the slide members at the rear of the assembling space groove and the tying spots to wind the shoelace cord, forming the variable ratio control tying of shoelace;
• and
• a control mechanism, aligned with an insert member and assembled in a control groove of a sole, at a rear of the control groove is a through hole for a button, to push the snap plate inside the control box, to control the insert member to engage it when the shoe is put on and disengage it when the shoe is taken off.
