Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an undershirt for sports mainly used in cold seasons, for example, for a marathon, and to timely adjust the body temperature as the body temperature rises during a marathon. With the goal.

[0002]

2. Description of the Related Art In a marathon, a hot marathon runs with one running shirt.
In cold weather marathons, it was common to wear long-sleeved shirts under running shirts as a measure against the cold before and immediately after the start. Further, as disclosed in JP-A-2-91201 and JP-A-3-18116, the shoulder portion and the side portion of the undershirt are detachable, and the undershirt can be taken off while wearing the upper garment. Although there were many, they did not take off gradually as body temperature rose, but took off at once. Further, as disclosed in Japanese Utility Model Laid-Open No. 48-51506 and Japanese Utility Model Laid-Open No. 56-126419, there are also those having the structure disclosed above and those being detachable at the center of the upper garment. Was mainly used for patients and did not respond to cold or heat.

[0003]

Immediately after the start of the marathon, the body temperature has not risen yet, and a long-sleeved shirt worn under a running shirt is just right as a measure against the cold.
As the running distance becomes longer, the body temperature rises and becomes hotter,
It is necessary to take off long-sleeved shirts and control the rise in body temperature. However, it is very difficult to take off the long-sleeved shirt while running, and there is a drawback that if one is distracted from taking off the shirt, he / she can concentrate. In addition, the body temperature does not rise at once, but gradually rises as the running distance increases. If the body temperature rises to a certain extent and the user takes off the undershirt at a stretch, the body may suddenly cool down. Therefore, what can be taken off gradually for each part of the undershirt according to the rise in body temperature has been desired.

[0004]

SUMMARY OF THE INVENTION Accordingly, the sports undershirt according to the present invention has a simple and step-by-step upper garment as the body temperature rises in marathons, long distance running, other competitive sports, mountain climbing and other sports. A detaching portion is formed so as to be able to be detached.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is directed to a body length direction of a front part and a back part of an upper garment or a sleeve-fitted portion or a portion between a sleeve-fitted portion and an elbow so as to be easily taken off with a rise in body temperature in sports. A sports undershirt characterized in that a detachment portion is provided at an arbitrary position. The upper garment referred to here is a sports undershirt including a front body, a back body, and a sleeve. In the following, the central part of the upper garment will be referred to as part A,
The sleeved portion is defined as portion B, and an arbitrary portion (short sleeve cuff portion) between the sleeved portion and the elbow portion is defined as portion C.

The above-mentioned upper garment is worn under a running shirt, for example, to protect the body from the cold before or immediately after the start of the marathon.
After running a few kilometers, if the body temperature rises to a certain extent, it first leaves section C to become a short-sleeved undershirt. Furthermore, if the running distance increases and the body temperature rises, then the part B is removed to form a running type undershirt. Further, if the running distance increases and the body temperature rises, all the undershirts can be taken off by removing the part A, and a running shirt is worn.

The material of the upper garment is a woven or knitted fabric, for example, synthetic fibers such as polyester, polyamide, polypropylene, and acrylic, and natural fibers such as cotton and wool. Examples of the synthetic resin film and the synthetic resin sheet include polyethylene, polypropylene, polyurethane, and vinyl chloride. The non-woven fabric is made of polyester, polyamide, polypropylene, acrylic, etc. There are two types of manufacturing methods, one using an adhesive and one using no adhesive. A production method by a punch method or a hydroentanglement method is preferable. When the upper garment is made of non-woven fabric or paper, it is desirable that the surface be subjected to water repellent treatment.

[0008] The release portion, a hook-and-loop fastener, a snap,
A detachable locking tool such as a button is possible. Also, such as disposable, non-woven fabric, paper or other easily breakable or reusable even if broken, synthetic resin film,
It is possible to use a synthetic resin sheet bonded to an upper garment with an adhesive or heat fusion. Also, the material having a low tear strength, for example, even if the undershirt body and the release portion are made of a nonwoven fabric of the same material, the thickness of the nonwoven fabric of the undershirt body is increased, or the amount of needle punch is increased, A material in which the amount of fiber leach is increased, while the thickness of the detached portion is reduced, and the tear strength of the detached portion is reduced by reducing the amount of needle punch.

Also, the synthetic resin film can be more easily separated by changing the thickness of the film or by forming a perforated cut line in the separated portion. It is desirable that the perforation cut line is formed by opening the perforation of the part C to be detached first and making it smaller from the part B to the part A so that the part A is not detached first when detached. Further, if a cut is made in advance in the perforation cut line, the separation becomes easier.

[0010]

An embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, a detachable portion 3 is provided at a short sleeve cuff portion C, a front body 4 and a central portion A of a back body 5 of the upper garment 2 so that the long sleeve upper garment 2 can be detached. . In the sports undershirt 1 of the embodiment, a knitted fabric is used as a material forming the upper garment 2, a non-woven fabric is used as the detachment portion 3, and the upper garment 2 and the detachment portion 3 are sewn. The knitted fabric used here is a tricot warp knitted fabric using 75 denier and 50 denier polyester yarn. The non-woven fabric is a fabric formed by a hydroentanglement method using 100% of polyester yarn. Further, perforated cut lines 6 were provided on the nonwoven fabric so as to be more easily separated.

As shown in FIGS. 3 and 4, a sports undershirt 1 is worn under a running shirt 7, and FIG. 3 shows a cuff 8 of the upper garment 2 as the body temperature rises.
, The short-sleeved cuff portion C is cut off to form a short-sleeved sports undershirt 1.
Further, as shown in FIG. 4, when the body temperature further rises, pulling the upper garment 2 from the shoulder opening cuts the central portion A of the front body 4 and the back body 5 so that the body can be easily removed from the left and right shoulder openings one by one. it can.

A perforated cut line 6 is provided at the central portion A of the front body 4 and the rear body 5 and at the detachable portion 3 of the short sleeve cuff portion C.
Was 1 mm for the cut portion and 1.5 mm for the uncut portion. Further, the pitch length of the perforated cut line 6 of the short sleeve cuff C portion between 100 mm is 3.5 mm for the cut portion, 1.5 mm for the uncut portion, and the perforated cut line 6 for 100 mm.
By making it easier to detach.
