ELASTIC CORELESS ROPE BELT

Abstract

An elastic coreless rope belt is a tubular braided rope of no core with stretch elasticity. Wherein the center part of the elastic rope belt along its length keep the same hollow shape, and at the periphery of the rope, it is provided with protruded knot parts of plural middle segment. At the plural middle segment, the diameter of the protruded knot can be changed with the changing of the axial tension. Once the axial tension is relived, the diameter and the shape will return to the origin. Thereby, it is convenient to make position limited buckling and loosening to the object hole.

DETAILED DESCRIPTION OF THE INVENTION

[0032] Please refer to FIG. 2 to FIG. 6, elastic rope belt 2 of this invention is an elastic coreless tubulose braided rope belt, in which the center part 21 of this elastic rope belt 2 keeps same hollow shape along its length, and plural protruded knot part 23 and plural middle segment 22 will be alternately configured outside the elastic rope belt along its length, the protruded knot part 23 is the part flexing fiercely, the protruded knot diameter D2 of the protruded knot part 23 is larger than aperture D2 of hole 31 on material 3, and the diameter of protruded knot diameter D2 will change with axial tension, the minimal diameter D4 of protruded knot part 23 which can bear axial force is less than aperture D3 of hole 31 of its object, and returns to original protruded knot diameter D2 and shape after the axial force is relieved, the middle segment 22 is the part which flexes not fiercely, the basic diameter D1 of middle segment 22 can pass through aperture D3 of hole 31 of its object with no axial force, and make up via this structure, making it convenient for object 3 to grip and release.

[0033] The protruded knot part 23 and middle segment 22 in this invention are alternately configured in elastic rope belt 2, and change the protruded knot diameter D2 of protruded knot according to axial tension.

[0034] The elastic rope belt 2 of this invention, its so-called protruded knot part 23 means the cord is compared to the basic diameter D1 of the middle segment 22 with no axial tension, and has part with protruded knot diameter D2; the weaving mode of elastic rope belt 2 executes transportation speed with variable proportion, making the weaving density distributing on every point of protruded knot part 23, which is to control the stretching rate of each point on protruded knot part 23 with different weaving density ratio, making the weaving density of protruded knot part 23 higher than that of middle segment 22, and forming a protruded knot part and shape with that protruded knot diameter; the protruded knot part 23 can be in any shape, and protruded knot part 23 can be divided into symmetry, non-symmetry and mixed type according to its shape, in which the shape of symmetry type can be the protruded knot part 23A (as shown in FIG. 7) of corniform, protruded knot part 23B (as shown in FIG. 8) of circular arc, the part with higher stretching rate has higher weaving density; it can be known from the curvilinear relationship in FIG. 11, that the maximal part of protruded knot part 23 is the part of protruded knot diameter D2, uniformly distributing on both sides of it, and the shape corresponding to protruded knot part 23 distributes likewise;

[0035] the shape of non-symmetry type can be protruded knot part 23B (as shown in FIG. 8) of a circular arc; it can be known from the curvilinear relationship in FIG. 12, that the maximal part of protruded knot part 23 is the part of protruded knot diameter D2, but not in the middle, not uniformly distributing on both sides of it; the shape of mixed type arranges along the elastic rope belt 2, including over 2 protruded knots of 23C, 23D, 23E, 23F (as shown in FIGS. 9 and 10) in different shapes; these protruded knots have a same feature, that the protruded knot diameter D2 is larger than aperture D3 of hole 31 of its object, which enables protruded knot part 23C, 23D, 23E, 23F form limit clamp to hole 31, when relieving clamp, stretching the elastic rope belt 2 toward one end or two ends, to make protruded knot part 23, 23A, 23B, 23C, 23D, 23F distorting along axis; when the minimal diameter D4 is less than aperture D3 of hole 31 of object 3, the protruded knot part 23, 23A, 23B, 23C, 23D, 23F can pass through hole 31, making it convenient to limit clamp and relieve clamp; when the axial tension is relieved, the protruded knot part 23, 23A, 23B, 23C, 23D, 23F will return to the original protruded knot diameter D2 and shape; taking FIG. 10 as an example, the protruded knot part 23F has a big protruded knot part and a small one, and it can be known from the curvilinear relationship in FIG. 13 that the protruded knot part also presents the relation between maximal protruded knot value.

[0036] Relatively, the weaving length L1 (please refer to FIG. 2) of the middle segment 22 is the part which flexes not fiercely when bearing axial force; the weaving length L2 of the protruded knot part 23 is the part which flexes fiercely when bearing axial force; the length it can stretch depends on the use demand, and reach a maximum weaving length of 3-5 times of weaving length L2.

[0037] The elastic rope belt 2 of this invention is an elastic coreless tubulose braided rope belt, whose material is chosen from natural rubber, synthetic rubber, polytetramethylene ether glycol, mixed or weaved fiber (including nylon fiber, polyester fiber), the elastic rope belt 2 can be weaved into a coreless tubulose braided rope belt, it can also mixed weaved into elastic rope belt 2 with elastic or inelastic material according to certain ratio.

[0038] The elastic rope belt 2 of this invention is a coreless tubulose braided rope belt, in which the center part 21 keeps same hollow shape along its length, and its advantage is the elastic rope belt 2 can keep its shape unchanged depending on its elastic supporting feature when it's not bearing force, there is enough storage and flexing space between the internal side 231 of protruded knot part 23 and the center part 21, so when punching a hole on the shoe, there is no limit of traditional-style central rope core, and the protruded knot part 23 has more elasticity, which won't generate pressure on the navicular bone, sphenoid bone and articulations of metatarsal bones, and make the wearer feel comfortable.
