ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a string fastening device for tightening and fastening a string threaded along the periphery of sleeve, waist, collar, and hood of ski wear, quilted down jacket with hood, half coat and the like, a string fastening device generally called code stopper, which is provided at an end of a tightening string and allows adjustment of tightening of the string and a cloth to which the string fastening device is attached at a mouth of the threading hole and allows tightening of the string.
2. Description of the Related Art
According to a conventional string fastening device disclosed in Japanese Utility Model Publication No. 47-5867, as shown in
FIG. 40
, a hole
4
′ is made in the center of a thin metal plate so that a round string S′ or the like can be threaded thereinto. Engaging holes
5
′ having a peripheral portion formed with uneven surface are punched out in the same diameter as or a slightly smaller diameter than that of the round string, next to this hole
4
′ to be continuous.
Further, according to Japanese Patent Laid-Open Publication No. 9-252813, as shown in
FIG. 41
, a tapered penetrating hole
3
′ is made in the center of a string fastener main body
1
′ formed by injection molding using elastic material such as mild synthetic resin and rubber, so that it allows a string threaded into this penetrating hole
3
′ to move in a single direction with respect to the string fastener main body
1
′, while a large resistance is applied if the string is moved in an opposite direction.
Further, according to Japanese Patent Laid-Open Publication No. 9-56420, in a string fastening device having a string braking passage portion
5
″ in the center, a front main body
1
″ having a restricting piece
9
″, which is provided around the string braking passage portion
5
″ and deformable by resistance generated when the string passes the passage portion, is made of elastic member such as urethane rubber and flexible plastic. The front main body
1
″ is circular in its plan view and an ornament portion having unevenness such as a letter, graphic or the like is formed on the surface of the main front body
1
″. A crimping cylindrical leg
30
″ formed by punching out thin stainless sheet has a jaw
31
″ to be buried at an end thereof. Then, with the center of the crimping cylindrical leg
30
″
0
coinciding with the center of the braking passage portion
5
″, the jaw
31
″ is buried in the front main body
1
″ such that the crimping cylindrical leg
30
″ is protruded from the center of the rear face of the front main body
1
″. A rear body
2
″ of this fastening device is formed by punching out a stainless sheet into a ring shape having a center hole in which the crimping cylindrical leg
30
″ can be inserted.
As for the string fastening device shown in
FIG. 40
, the string passage portion hole is formed in the center of the thin metal plate and engaging holes having an unevenness on the periphery thereof are made beside this hole such that they adjoin. During use, the unevenness bites into the string so as to prevent it from slipping out. Because of the thin metal sheet, if the unevenness of the engaging hole bites into the string more firmly than expected and then the string is pulled to tighten with a strong pressure, the string may be damaged. Thus, this fastening device cannot be adjusted accurately in tightening force and cannot be used for a long term.
In the string fastening device shown in
FIG. 41
, its main body is formed of elastic material such as mild synthetic resin and rubber. Because the main body is likely to be elastically deformed through a cut-in portion disposed in a tapered face of a penetrating hole provided therein, a string threaded into the fastening body can move in an opposite direction as well as in a predetermined direction. Adjustment of the tightening of the string is carried out by this single penetrating hole. Therefore, this string fastening device has such a problem that the main body is likely to be loosened during use so that it may lose its tightening function. In case of attaching the main body to an article by sewing, an accurate sewing is hardly realized because of lack of any guide groove for sewing. Further, even if the main body is made of elastic material, a sewing thread exposes on the surface so that it would get worn out.
The string adjustment fastening device shown in
FIG. 42
is formed of elastic member such as urethane rubber and resin. A braking passage portion is provided in the center thereof and a braking piece which is bent and deformed by a passage portion resistance of the string is disposed on the periphery of the braking passage portion. The braking piece is protruded into the braking passage portion in a tongue shape. Even if the string is moved in either forward and backward, movement of the string is stopped by the bending and deformation of the braking piece with pressure. Thus, the string is likely to be loosened during use so that the adjustment of the tightening is instable. In order to attach the fastening adjustment device to a cloth, the crimping cylindrical leg formed by punching a stainless sheet and then pressing is buried integrally in the main body of the elastic member and this crimping cylindrical leg is crimped to the rear fastening body made of stainless. Therefore, the adjustment fastening device is composed of the elastic member and the crimping cylindrical leg made of stainless. Then, this adjustment fastening device must be buried. Thus, there is such a problem that production of the fastening device is very troublesome and the components cannot be recycled.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been achieved in views of the above described problems. An object of the invention is to provide a string fastening device whose main body has a penetrating hole in which a string can be threaded, the penetrating hole being comprised of a passage portion allowing the string to pass freely and a passage portion for restricting movement of the string, the string fastening device having a structure facilitating adjustment operation of tightening of the string and capable of gripping and capturing the string securely and bearing a long term use. Further, this string fastening device can be produced easily.
Another object of the invention is to provide a cloth to which a string fastening device is attached, the string fastening device including a penetrating hole being comprised of a passage portion allowing the string to pass freely and a passage portion for restricting movement of the string so that adjustment operation of fastening of the string can be done easily, the fastening device being able to be attached to the cloth only with a main body thereof.
Another object of the invention is to provide a string fastening device having a structure with which the main body can grip and capture the string reliably and easily.
Another object of the invention is to provide a string fastening device in which the string is not permitted to change its path except intentionally between a passage portion allowing the string to be moved freely and a passage portion for restricting movement of the string, so as to distinguish the sliding of the string from the braking function clearly.
Another object of the invention is to provide a string fastening device having a passage portion for restricting movement of the string, having a shape suitable for the string depending on material and shape of the string upon use of the string fastening device.
Another object of the invention is to provide a string fastening device having a passage portion capable of holding the string in an excellent tightening condition and restricting movement of the string effectively and appropriately.
Another object of the invention is to provide a string fastening device, which is comprised of a main body a
