Abstract
Description
- The present invention relates to a coil hair tie, and more particularly to a coil hair tie having an elastic restoring force.
- A hair ring is a commonly used device for tying hair, such as a ponytail. After the hair is tied with a conventional linear circle of hair ring, the hair often leaves a dent as being pressed by the hair ring. Even if the linear circle of hair ring is covered by a fabric to form a scrunchie, similar problems still exist. The coil hair tie as shown in
FIG. 1 is popular because it causes little or no trace after the hair is tied and then released. Such coil hair ties are usually made of a thermoplastic plastic material such as TPU (Thermoplastic polyurethanes) or TPR (Thermoplastic rubber), which achieves stretching and recovery objects through a spiral-shaped structure 1. Although such materials have a certain degree of elasticity, they do not have sufficient elastic restoring force like the general elastic hair ring under the consideration of the hardness required for molding. Therefore, after the conventional coil type hair ring is used repeatedly, the coil will become looser and looser and the density of the coil will become lower and lower, and there will be no effect of tightening the hair any longer. - To solve this problem, German Patent No.
DE 102015115002 B3 discloses a two-component hair ring consisting of a spiral TPU-ring and a corrugated rubber ring inside the TPU-ring. This type of hair ring includes a wavy or spiral hair ring made of a material that is less elastically fatigued inside the conventional coil type hair ring, thereby extending the strength and durability of the coil type hair ring. Although this kind of improvement helps to improve the strength and durability of the conventional coil type hair ring, the complicated inner ring manufacturing is disadvantageous in cost and process, and the inner and outer spiral coils may have entanglement problems. The effect of maintaining the density of the outer ring coil is also limited, as it is also necessary to sacrifice the elastic restoring force of the inner ring material, like the outer ring, in order to maintain its configuration. - Therefore, there is a need to develop a hair ring having a relatively simple structure, which can have non-marking and non-tangling effects of a coil type hair ring, and meanwhile, can have sufficient elastic restoring force to improve strength and durability.
- A coil hair tie includes: a spiral coil body configured as a head-to-tail connected ring with a hollow portion for allowing hair to pass through, wherein the spiral coil body has a hollow chamber therein; and a linear elastic restoring member comprising at least one one-dimensional elastic body extending in a direction substantially parallel to the spiral coil body and disposed in the hollow chamber of the spiral coil body, and being head-to-tail connected to form a ring configuration. When the spiral coil body is stretched into a tensile configuration with a lower coil density, the elastic restoring member is also stretched, and when the tensile force applied to the spiral coil body is removed, the spiral coil body restores to a retracted configuration having a higher coil density through the tensile restoring force of the elastic restoring member.
- The linear elastic restoring member may consist of two or more one-dimensional elastic bodies of different materials, sizes and configurations.
- The above contents of the present invention will become more readily apparent to those ordinarily skilled in the art after reviewing the following detailed description and accompanying drawings, in which:
-
FIG. 1 is a schematic diagram illustrating a conventional coil type hair ring; -
FIG. 2A is schematic diagram illustrating a coil hair tie according to a first embodiment of the present invention; -
FIG. 2B is schematic diagram illustrating a cross section of the coil hair tie ofFIG. 2A , which is taken along the A-A line; -
FIG. 3 is a schematic diagram illustrating the use of a coil hair tie according to the present invention; -
FIG. 2A is schematic diagram illustrating a coil hair tie according to a second embodiment of the present invention; -
FIG. 4B is schematic diagram illustrating a cross section of the coil hair tie ofFIG. 4A , which is taken along the B-B line; -
FIG. 5 is a schematic cross-sectional view of an elastic restoring member of a coil hair tie according to a third embodiment of the present invention; and -
FIG. 6 is a schematic partial perspective view of an elastic restoring member of a coil hair tie according to a fourth embodiment of the present invention. - Referring to
FIG. 2A , a coil hair tie according to a first embodiment of the present invention includes aspiral coil body 10, which is integrally formed or joined to form a head-to-tail-connected ring-shaped member so that theentire coil body 10 forms a hair ring with ahollow portion 11 for allowing hair to pass through. Furthermore, thecoil body 10 itself is configured to have ahollow chamber 101. The coil hair tie according to the present invention additionally includes at least one linearelastic restoring member 20, which is formed of a one-dimensional elastic body extending substantially in a linear direction (parallel to the spiral coil body) and forming a head-to-tail phase in an integrally formed or joined manner, and extensively disposed in thehollow chamber 101 of thecoil body 10. In the present embodiment, only one one-dimensional elastic body is disposed in thehollow chamber 101 of thecoil body 10 as theelastic restoring member 20, as shown inFIG. 2B , which is taken along the line A-A ofFIG. 2A . When the user stretches thecoil body 10 as shown in steps A and B ofFIG. 3 , theelastic restoring member 20 is also stretched, and when the user loosens the coil body as shown in step C ofFIG. 3 , thecoil body 10 can restore to its initial coil density by way of the restoring force of theelastic restoring member 20 for subsequent uses. The one-dimensionalelastic body 20 used in this embodiment may be any suitable material having stretch characteristics, such as natural or synthetic rubber, plastic, latex or a mixture thereof generally used for producing hair rings. The size design should be compatible with the size and material of the coil body. The size of thecoil body 10 is matched with the material, which should not be too thin to cause breakage or elastic fatigue when stretching together with thecoil body 10, nor should it be too thick to make thecoil body 10 difficult to stretch. - Next, please refer to
FIG. 4A and FIG. 4B to see a coil hair tie according to a second embodiment of the present invention, whereinFIG. 4B is a schematic cross-sectional view taken along line B-B of the coil hair tie shown inFIG. 4A . In the present embodiment, the linearelastic restoring member 20 provided in thehollow chamber 101 of thecoil body 10 includes two one-dimensionalelastic bodies elastic bodies coil body 10 to stretch and elastically recover. The advantage of providing two or more one-dimensional elastic bodies is that when one of them is broken or elastically fatigued, there is another one that can support the elastic restoring force, and the color and style of the hair ring can be more varied. - The one-dimensional
elastic body 20 illustrated in the first embodiment, the one-dimensionalelastic body elastic body protective material 200, which has a lower stretchability than the one-dimensional elastic body, e.g. an elastic cloth, as shown in the cross-sectional view ofFIG 5 . In addition to beautification, the purpose of theprotective material 200 is to confine the stretch range of the one-dimensionalelastic body 20 to avoid breakage due to excessive stretching and, in addition, to protect the hair from being adhered by the one-dimensionalelastic body 20. -
FIG. 6 shows a linearelastic restoring member 20 included in a coil hair tie according to a fourth embodiment of the present invention. The linearelastic restoring member 20 in this embodiment is formed by interweaving two one-dimensionalelastic bodies elastic bodies spiral coil body 10, and when one of them is broken or elastically fatigued, there is another one that can support the elastic restoring force, and the color and style of the hair ring may be variable. - In summary, the coil hair tie structure according to the present invention has the advantages of not leaving traces on hair after being tied to and released from the hair, and having better durability. In addition, it has been comprehensively considered in aesthetic design and cost control.
