Heat dissipation mechanism of sports jackets

Abstract

A heat-dissipating structure for a sports jacket comprises a jacket body made of a pair of front chest fabrics sewn together with a back back fabric; a front zipper is sewn onto the front opening between the pair of front chest fabrics; a back zipper is sewn onto the back back fabric with a row of heat vents, the back zipper having at least one pull tab that can move along the heat vents, causing the back zipper teeth to engage or disengage, thus closing or opening the heat vents; by opening the heat vents, body heat can be expelled, thereby effectively reducing body stuffiness and improving comfort when the jacket is worn for extended periods.

Claims

1. A heat dissipation structure for a sports jacket, comprising a jacket body made of a pair of front chest fabrics sewn together with a back fabric; a sleeve is sewn onto each side of the jacket body; a collar is sewn onto the upper part of the front opening between the pair of front chest fabrics, and a front zipper is sewn onto the front opening between the collar and the lower edge of the jacket body; the front zipper has at least one front pull head, each front pull head having a front pull tab, which can be operated by the front pull tab to move the at least one front pull head along the front opening, causing the front zipper teeth to engage or disengage, thereby closing or opening the front opening; a heat vent is also provided on the back fabric, and a rear zipper is sewn onto the heat vent; the rear zipper has at least one rear pull head, each rear pull head having a rear pull tab, which can be operated by the rear pull tab to move the at least one rear pull head along the heat vent, causing the rear zipper teeth to engage or disengage, thereby closing or opening the heat vent.

2. The heat dissipation structure of the sports jacket as described in claim 1, wherein, The zipper sewn onto the heat vent has two pull tabs facing opposite directions. One pull tab is located above the heat vent and can be pulled downwards to make the zipper teeth mesh. The other pull tab is located below the heat vent and can be pulled upwards to make the zipper teeth mesh.

3. The heat dissipation structure of the sports jacket as described in claim 2, wherein, The heat vent is an open fabric opening at the lower edge of the garment where the back fabric is cut off. The back zipper is sewn onto the heat vent. The other back pull is for inserting a back insert rod and fastening it to a back box. When pulled upwards, it can cause the back zipper teeth to mesh with each other.

4. The heat dissipation structure of the sports jacket as described in claim 1, wherein, The rear zipper sewn onto the heat vent has two rear pull heads facing opposite directions. One of the rear pull heads is located above the heat vent and can cause the rear zipper teeth to separate and not engage when pulled downwards. The other rear pull head is located below the heat vent and can cause the rear zipper teeth to separate and not engage when pulled upwards.

5. The heat dissipation structure of the sports jacket as described in claim 4, wherein, The heat vent is an open fabric opening at the lower edge of the garment body where the back fabric is cut off. The back zipper is sewn onto the heat vent. The other back pull is a pull that is stopped by a pair of lower stops to restrict it from retracting from the back zipper teeth.

6. The heat dissipation structure of the sports jacket as described in claim 1, wherein, The front zipper sewn onto the front opening between the two front fabric panels has two front pulls facing opposite directions. One front pull is located below the front opening, through which a front insert is inserted and fastened to a front box. When pulled upwards, the front zipper teeth can be engaged. The other front pull is located above the front opening, through which another front insert is inserted and fastened to another front box. When pulled downwards, the front zipper teeth can be engaged.
