1. Field of the Invention
The present invention relates to headwear such as a cap, a hat and a visor cap. More particularly, the present invention relates to elastic headwear with an elastic head-wearing portion having exposed stitches to fix a lower hem thereof.
2. Background of the Invention
Conventional elastic headwear such as a cap, a hat and a visor cap includes an elastic head-wearing portion and a stretchable sweatband. The head-wearing portion is a crown portion in a cap or a hat. It may be a circumferential strap which encircles the head of a user in a visor cap.
In the case of a cap or a hat, the elastic crown portion which is composed of a stretchable fabric that includes a stretchable strand is flimsy and difficult to maintain in its semispherical shape, so it has drawbacks in that it is easily wrinkled or crushed when being carried and displayed. Further, when the elastic crown portion is coupled with the stretchable sweatband, it is rumpled around its lower hem. When the headwear is used repeatedly for a long time, it usually suffers from overstretch, resulting in enlargement of the size of the crown portion.
In order to overcome the drawbacks of the conventional elastic headwear, headwear using latex threads which is disclosed in Korean Utility Model Publication No. 20-0314989 B has been proposed. An elastic crown portion in the headwear is coupled to a stretchable sweatband in chain stitches (specifically double chain stitches as shown in
In view of the prior art described above, it is an object of the present invention to provide elastic headwear which is capable of retaining its shape through exposed stitches that fix a lower hem to its crown portion.
It is another object of the present invention to provide headwear with exposed stitches which prevent its elastic crown portion from being deformed due to long and repeated uses.
It is still another object of the present invention to provide elastic headwear with exposed stitches which are difficult to snap, and that are difficult to unravel even if they do snap.
To achieve these and other objects, as embodied and broadly described herein, headwear includes a head-wearing portion being stretchable in at least a circumferential direction thereof; and exposed stitches which are viewed outside and are disposed along a lower hem of the head-wearing portion.
The exposed stitches are formed of a stretch yarn as a bobbin thread and a non-stretch yarn as an upper thread. The stretch yarn is preferably selected from a spandex yarn, polyurethane yarn, polyurethane covered yarn, latex yarn, and highly-twisted yarn.
Preferably, the exposed stitches are lock stitches.
A stretch tape may be attached the inside of the lower hem, or attached between a folded portion of the lower hem when a lower edge of the crown portion is folded to form the lower hem. Further, a stretchable sweatband may also be attached along the inside of the lower hem by the exposed stitches.
According to another aspect of the present invention, a method of forming headwear includes:
forming a crown portion which is stretchable in at least a circumferential direction thereof;
folding a lower edge of the head-wearing portion so as to form a lower hem; and
stitching along the lower hem with a stretch yarn as a bobbin thread and a non-stretch yarn as an upper thread.
The stitches from the stitching along the hem are exposed outside.
BRIEF DESCRIPTION OF THE DRAWINGSThe accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate an embodiment of the invention, and, together with the description, serve to explain the principles of the invention:
Preferred embodiments of the present invention will hereinafter be described in detail with reference to the accompanying drawings, where like numerals of reference designate like elements throughout.
Referring to
The crown portion 100 is composed of a plurality of elastic pieces which have elasticity, in at least a lower hem 150.
A stretchable sweatband 300 and stretch tape 400 are provided along the inside of the lower hem 150. The stretchable sweatband 300 is stretchable at least in a circumferential direction. The stretch tape 400 is also stretchable at least in the circumferential direction and is made of woven, knit or non-woven elastic fabrics. The stretch tape 400 serves to prevent the crown portion 100 from extending excessively as well as to support the shape of the crown portion 100 firmly and elastically.
Stitches 500 which are exposed outside may fix a lower hem 150 of the crown portion 100 as well as a stretchable sweatband 300 and stretch tape 400. The stitches 500 are preferably lock stitches as shown in
Because the stitches 500 press and fix the sweatband 300 with respect to the crown portion 100, additional short stitches are unnecessary to secure the sweatband as in a conventional elastic cap.
Referring to
Since the lock stitches 500 are formed of a stretch yarn as a bobbin thread 520 and a non-stretch yarn as an upper thread 510, they prevent the crown portion 100 and the sweatband 300 from being stretched excessively during a long period of use. The lock stitches 500 fix the sweatband 300 to the crown portion 100 without additional short fixing stitches. As a result, the cap may retain its shape since the lower hem is firmly stitched.
Further, since the lock stitches 500 are exposed outside, they may serve to give ornament effects.
A stretchable sweatband 300 is provided along the inside of the lower hem 150. The stretchable sweatband 300 is stretchable at least in an elongated direction.
Stitches 500 which are exposed outside may fix a lower hem 150 of the crown portion 100 as well as a stretchable sweatband 300. The stitches 500 are preferably lock stitches as shown in
A stretch tape 400 is provided along the inside of a lower edge of the crown portion 100 and then folded with the lower edge to form the lower hem 150. The stretch tape 400 is stretchable at least in an elongated direction and is made of woven or non-woven elastic fabrics. The stretch tape 400 serves to prevent the crown portion 100 from excessively stretching as well as to support the shape of the crown portion 100 firmly and elastically.
Stitches 500 which are exposed outside may fix a lower hem 150 of the crown portion 100 as well as a stretch tape 400.
A lower edge of the crown portion is folded and then stitched by the lock stitches composed of a stretch yarn as a bobbin thread 520 and a non-stretch yarn as an upper thread 510 as shown in
As described above, according to headwear of a preferred embodiment of the present invention, elastic headwear is capable of retaining its shape through exposed stitches to fix the lower hem. Therefore, such headwear is hardly deformed during long and repeated uses.
Although the present invention is implemented as a cap in the preferred embodiments as describe above, the present invention may be a hat, a visor cap, or other various kinds of headwear having a head-wearing portion portion, not being limited to the cap.
While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
