Abstract
To eliminate the inconvenience of putting on and taking off lace shoes, to disperse the pressure sensation applied to the instep of the foot due to tightening at the time of putting on, and to ensure near-equal tightness of the shoelace tension after putting on with relative ease. A lace shoe is provided with blade parts inside and outside, one blade part having one more shoelace-throughs arranged than the other, a single shoelace alternating between shoelace-throughs arranged in both blade parts and passing through all shoelace-throughs with the shortest path length. A binding tool tying both ends of the shoelace in the same direction is locked to a binding-tool stop fixed to the upper part of the lace shoe.
Claims6
A lace shoe that can be tightened according to the circumference of each part of a foot, regarding the right or left half foot of the lace shoe, the lace shoe comprising:
- both blade parts of shoelace-stay installed on an inner and an outer side of an upper part of the lace shoe, the inner side and the outer side being defined in terms of directions of a part of a shoe, wherein the inner side corresponds to a big toe side and the outer side corresponds to a little toe side of the foot when worn in a shoe;
- a group of shoelace-throughs arranged on the both blade parts with one greater number of shoelace-throughs in one blade part than the other blade part, the shoelace-throughs forming a single row on each blade part, the single row of shoelace-throughs on each blade part having the same length between either end stage of the row, such that the one greater number of shoelace-throughs does not extend beyond an end stages of either row;
- a single shoelace that alternately tightens the inner side and the outer side, passes through all of the group of shoelace-throughs, and can be closed by tying both ends of the shoelace;
- starting and ending shoelace-throughs that are starting and ending points of the single shoelace in the group of shoelace-throughs, the starting and ending shoelace-throughs being two adjacent points that are both at a location other than either of the end stages of the row, the end stages being aligned in a transverse direction to the row, the starting and ending shoelace-throughs being placed on the one blade part, having the shortest path among all the paths of the single shoelace between the starting and ending points;
- a binding tool positioned in alignment with the two adjacent points in the transverse direction, the binding tool being that with which is tied both ends of the single shoelace in the same direction, allowing the single shoelace to be pulled from the shoelace-throughs continuous to the starting and ending shoelace-throughs in directions of sections between two continuous shoelace-throughs, further allowing the single shoelace to be pulled facing diagonally upward, wherein the sections constitute starting and ending shoelace-throughs sections;
- and
- a binding-tool stop that is fixed to the upper part on the side of the other blade part where the starting and ending shoelace-throughs are not placed, locking the binding tool.
