Lace Structure

Abstract

A lace structure includes a plurality of weaving threads and a plurality of resilient threads which are interlaced in a lengthwise direction to form an elongate lace which defines a plurality of first sections and a plurality of second sections arranged in an alternating manner. Each of the second sections of the lace has a weaving density greater than and a width smaller than that of each of the first sections. In such a manner, each of the first sections of the lace has a wide face with a low density, and each of the second sections of the lace has a narrow face with a high density. Thus, each of the first sections of the lace has an elasticity greater than that of each of the second sections, so that the lace has a stepwise elastic function.

1 . A lace structure comprising:
 an elongate lace which is interwoven by a stitching machine;   wherein:   the lace includes a plurality of weaving threads and a plurality of resilient threads which are interlaced in a lengthwise direction;   the lace presents a successive shape during a weaving process and defines a plurality of first sections and a plurality of second sections arranged in an alternating manner;   the second sections of the lace are respectively arranged between the first sections;   each of the second sections of the lace has a weaving density greater than that of each of the first sections;   each of the second sections of the lace has a width smaller than a width of each of the first sections;   each of the first sections of the lace has a wide face with a low density, and each of the second sections of the lace has a narrow face with a high density; and   each of the first sections of the lace has an elasticity greater than that of each of the second sections, so that the lace has a stepwise elastic function.   
     
     
         2 . The lace structure of  claim 1 , wherein each of the second sections of the lace has two ends each formed with a loose zone. 
     
     
         3 . The lace structure of  claim 2 , wherein the loose zone has a weaving manner the same as that of each of the first sections and each of the second sections of the lace. 
     
     
         4 . The lace structure of  claim 2 , wherein the loose zone has a weaving manner different from that of each of the first sections and each of the second sections of the lace. 
     
     
         5 . The lace structure of  claim 2 , wherein the loose zone has a weaving density smaller than that of each of the second sections of the lace. 
     
     
         6 . The lace structure of  claim 1 , wherein each of the first sections of the lace has a length the same as or different from a length of each of the second sections of the lace. 
     
     
         7 . The lace structure of  claim 1 , wherein the resilient threads of the lace have a quantity smaller than that of the weaving threads of the lace. 
     
     
         8 . The lace structure of  claim 1 , wherein the weaving threads of the lace have different colors to present the lace with multiple colors. 
     
     
         9 . The lace structure of  claim 1 , wherein the weaving threads of the lace have the same color to present the lace with a single color. 
     
     
         10 . The lace structure of  claim 1 , wherein the weaving threads and the resilient threads are interlaced in the lengthwise direction to construct the lace, so that the lace has a tubular shape. 
     
     
         11 . The lace structure of  claim 10 , wherein the lace has an interior defining a plurality of cavities. 
     
     
         12 . The lace structure of  claim 11 , wherein the cavities of the lace are located in the first sections and the second sections and are connected with each other. 
     
     
         13 . The lace structure of  claim 11 , wherein an inner core is received in the cavities of the lace and is hidden in and encompassed by the first sections and the second sections of the lace. 
     
     
         14 . The lace structure of  claim 1 , wherein the weaving threads and the resilient threads are interlaced in the lengthwise direction to construct the lace, so that the lace has a flat shape.
