ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cord fastener, which is used by threading a tightening cord attached to a periphery of collar, waist, sleeve edge and hood of a ski wear, down jacket with hood, half coat and the like therethrough and fixed, or which is used to prevent the tightening cord from slipping out by being fixed to an end of the tightening cord, and further a cord fastener attached to an end of a gripping cord as a pull tab of slider of a slide fastener provided on the surface of a traveling caster bag or the like.
2. Description of the Related Art
As a conventional cord fastener through which the tightening cord is threaded, Japanese Utility Model Publication No. 1-39449 has disclosed a cord fastener in which as shown in
FIG. 16
, a cord insertion hole
15
′ is provided in a body portion
14
′ of a sliding body
2
′, a pair of leg portions
18
′ having an elasticity are provided below the body portion
2
′, while a cord insertion hole
15
′ is provided in a cylindrical body
1
′ having a bottom and a pair of slopes
9
′ are formed at a bottom portion inside the cylinder thereby providing the sliding body
2
′ with a resilient function by disposing the pair of the elastic leg portions
18
′ and the slopes
9
′ so that they oppose each other.
Further, Japanese Patent Laid-Open Publication No. 9-23909 has disclosed a cord fastener comprising, as shown in
FIG. 17
, a spherical main body
101
′ having a hollow portion
105
′ in which a sliding body
102
′ can fit and slide along a guide portion
108
′ and cord insertion holes
107
′ on both sides, the sliding body
102
′ having a pair of elastic leg portions
108
′ extending downward from a bottom face of a head portion
113
′ thereof and a pair of supporting pieces
121
′, while a cord insertion hole
115
′ is made in the supporting piece
121
′ such that a bottom of the head portion
113
′ is in contact with a top portion of the cord insertion hole
115
′. In this cord fastener, after the sliding body
102
′ is inserted into the main body
101
′ and an end of the tightening cord is inserted along the bottom face of the head portion
113
′, it is inserted through the cord insertion hole
107
′ in the main body
101
′ and the elastic leg portions
118
′ are resiled by the slopes formed at a bottom portion of the hollow portion
105
′, so that the sliding body
102
′ is resiled upward so as to fasten the tightening cord.
According to a cord fastener disclosed in Japanese Patent Laid-Open Publication No. 8-332104, in which an end portion of the tightening cord is nipped, as shown in
FIG. 18
, the cord fastener is formed of a pair of nipping bodies
3
′ having the same shape, and the nipping bodies
3
′ forms an opening through which the tightening cord is inserted, at an end thereof and contains an accommodating portion
25
′ for holding the tightening cord inward of the opening, several pieces of projecting portions
29
′ are provided so as to project on opposing faces of the accommodating portion
25
′ so as to hold the tightening cord, and engaging portions
27
′ for holding mating nipping bodies
3
′ are provided on both sides of the accommodating portion
25
′ to nip the end of the tightening cord.
Because both the cord fastener through which the tightening cord is threaded and the cord fastener in which an end of the tightening cord is nipped have a smooth surface, they are difficult to capture and fix, and therefore, the cord fastener swings freely when a user takes exercise wearing clothes using the same cord fastener or the wind is strong, thereby it is unsightly to see or it may hit the user's face.
SUMMARY OF THE INVENTION
Accordingly the present invention has been developed in views of the above problems, and therefore, an object according to a first aspect of the present invention is to provide a cord fastener made of thermoplastic resin, having a holding mechanism capable of capturing and holding the cord fastener in which a tightening cord is inserted through or an end of the tightening cord is nipped, with stability, the cord fastener having a surface fastener member on the surface of the cord fastener as the holding mechanism.
It is also an object of the invention to provide a cord fastener, through which the tightening cord is threaded, comprising a sliding body having an elasticity and a main body in which the sliding body can fit, wherein a surface fastener member is disposed on the surface of the main body as a holding mechanism.
Another object of the invention is to provide a cord fastener in which an end of the tightening cord is nipped, comprising a pair of nipping bodies of the same shape in which the nipping bodies are superimposed, wherein a surface fastener member is disposed on the surface of the nipping body as a holding mechanism.
Further object of the invention is to provide a cord fastener wherein a male portion of the surface fastener member is disposed as a holding mechanism on a surface of one side of the main body or combined nipping bodies of the cord fastener, the configuration of the male portion being specified so as to perform an excellent holding function.
Still further object of the invention is to provide a cord fastener, wherein a male portion, a female portion or female/male mixing portion of the surface fastener member is disposed as a holding mechanism on a surface of one side of the main body or combined nipping bodies of the cord fastener, thereby an excellent holding function being performed depending on use condition of each thereof.
Another object of the invention is to provide a cord fastener, wherein a surface fastener member is disposed as a holding mechanism on surfaces of both sides of the main body or combined nipping bodies of the cord fastener so that any of the surfaces is capable of engaging thereby performing an excellent holding function.
Still another object of the invention is to provide a cord fastener wherein a surface fastener member is disposed as a holding mechanism on the surface of the main body or nipping body and the other surface fastener member is disposed as a holding mechanism on the surface of a product using this cord fastener such that both the surface fastener members are capable of engaging with each other, thereby determining a holding place on the product so that the cord fastener can be fixed easily and provides a neat appearance.
To achieve the above objects, according to the invention, there is provided a cord fastener made of thermoplastic resin having cord insertion holes through which a tightening cord is threaded, wherein a surface fastener member is disposed by integral molding or fusing as a holding mechanism on an outside face of the cord fastener away from the cord insertion holes in the cord fastener.
Preferably, the cord fastener further comprises a sliding body having the cord insertion hole through which the tightening cord is inserted, passing to both sides and an elastic mechanism having an elasticity provided at a bottom thereof and a cylindrical or spherical main body engaging with the sliding body and having an escape preventing mechanism for preventing the sliding body from being escaped and the cord insertion hole through which the tightening cord passes, provided on both sides thereof, wherein the surface fastener member is disposed on an outside face of the main body.
Also preferably, the cord fastener further comprises a pair of nipping bodies which engage with each other by superimposing, wherein the cord insertion hole in which the tightening cord can be inserted is provided at a top portion of the pair of the nipping bodies, cord nipping mechanism is provided on opposing faces of the nipping bodies and the surface fastener member is disposed on an outside face of the nipping body.
