Elastic coreless rope belt
View Patent ↗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.
1. A coreless elastic rope belt for use with a material having at least one aperture, the coreless elastic rope belt comprising:
an elastic rope being an elastic coreless tubulose braided rope belt;
wherein, a center part of the elastic rope has a uniform hollow shape along a length thereof, and a plurality of protruded knots and a plurality of middle segments are alternatively positioned on an outside of the elastic rope along a length thereof, the plurality of protruded knots are flexible, each knot of the plurality of protruded knots has a protruded knot diameter that is larger than a diameter of the at least one aperture in the material;
wherein, when an axial tension is applied to stretch the length of the elastic rope, the protruded knot diameter of the each said knot of the plurality of protruded knots becomes a minimal diameter and the minimal diameter of each said knot of the plurality of protruded knots is smaller than the diameter of the at least one aperture in the material; and
wherein, when the axial tension is removed from the elastic rope, a diameter of each knot of the plurality of protruded knots returns to an original protruded knot diameter;
wherein the elastic rope belt is mixed weaved with an elastic material according to a predetermined weaving density ratio.
2. The coreless elastic rope belt according to claim 1 , wherein the plurality of protruded knots and the plurality of middle segments of the coreless elastic rope belt are alternately configured along the elastic rope belt.
3. The coreless elastic rope belt according to claim 1 , wherein the plurality of middle segments of the coreless elastic rope belt are less flexible than the plurality of protruded knots, and each middle segment the plurality of middle segments has a diameter that is smaller than the diameter of the at least one aperture in the material.
4. The coreless elastic rope belt according to claim 1 , wherein each said knot of the plurality of protruded knots has a weaving density that is higher than a weaving density of each middle segment of the plurality of middle segments thereby forming the plurality of protruded knots.
5. The coreless elastic rope belt according to claim 1 , wherein each said knot of the plurality of protruded knots has a shape on the coreless elastic rope belt that is symmetrical.
6. The coreless elastic rope belt according to claim 1 , wherein each said knot of the plurality of protruded knots has a shape on the coreless elastic rope belt that is non-symmetrical.
7. The coreless elastic rope belt according to claim 1 , wherein the plurality of protruded knots of the coreless elastic rope belt includes a mixture of symmetrical and non-symmetrical shapes, including the plurality of protruded knots consisting of over 2 different protruded knot shapes.
8. The coreless elastic rope belt according to claim 1 , wherein a weaving length of each said protruded knot is flexible, when the axial tension is applied, the weaving length of each said protruded knot is stretchable to a maximum weaving length of 3˜5 times an original weaving length.
9. The coreless elastic rope belt according to claim 1 , wherein the elastic rope belt consists of an elastic material, which is chosen from natural rubber, synthetic rubber, polytetramethylene ether glycol, mixed or weaved fiber.
