Headgear having insulated ventilation channels and perspiration and moisture drainage channel

Abstract

This headgear having insulated ventilation channels and perspiration and moisture drainage channel consists of top insulated ventilation channels 42 with front ventilation openings 44 and rear ventilation openings 60. Insulated side walls 46 with side ventilation openings 48. Rim with embedded perspiration and moisture drainage channel 50. Perspiration and moisture drainage channel 66 perspiration and moisture collection holes 64 and perspiration and moisture drainage holes and rim adjustment strap 54. Air circulates between front and back of top of headgear through insulated ventilation channels to aid in the removal of excess moisture and heat from the top of the wearer's head. Insulated side walls with ventilation holes aid in the removal of excess moisture and heat from the sides of the wearer's head. Perspiration and moisture from the wearer's head is removed through collection holes placed on the rim embedded perspiration and moisture drainage channel and drained through discharge holes placed at the ends of the drainage channel in the rear area of the headgear. Other embodiments are described and shown.

have developed a headgear that can assist in regulating temperature and managing perspiration and moisture levels generated by hot and humid conditions and or strenuous activities.

BACKGROUND

Headgear, caps, hats, are widely used in sports, recreational, military, law enforcement and various other types of activities. A vast majority of caps and hats currently being used during the aforementioned activities are made of light or thin fabrics, with the most popular and recognizable example being the baseball cap style hat. The baseball cap is very popular because it offers a large visor to protect the eyes from the sun's glare, is very light and it looks good, but offers limited protection from external heat sources such as direct sun light. In addition the baseball cap's light fabric construction is limited in its ability to regulate heat and moisture during hot and humid summer days, tropical weather conditions, and or strenuous physical activities.

Under high ambient temperature, humidity and or strenuous activities caps and hats become hot and saturated with perspiration and moisture causing the temperature of the wearer's head to rise. The human brain functions best within a certain range of temperatures and when these temperature ranges are lower or higher than adequate the body must compensate by taking resources from other organs. This transfer of energy from other parts of the body to maintain the brain within required temperature levels can affect the overall performance of individuals. This reduction in performance can be critical in situations such as high level sports competition and other strenuous and physically challenging activities.

Different types of light fabric headgear, caps and hats as well as adaptations and or alterations that can be incorporated or attached to better manage heat and moisture levels have been proposed. Although these variations and adaptations address heat and moisture discomforts, they require additional manipulation and components to function, and or are cumbersome to wear and or address one area of the over all heat and moisture discomfort. WO 94/09658 discloses means for ventilating and stabilizing headgear in the form of a flexible strip having, on one side, means of attachment to the headgear, and on its other side, a plurality of resilient or flexible spacers for spacing the headgear from a wearers head. A similar arrangement is proposed in U.S. Pat. No. 5,625,901. GB 713851 and U.S. Pat. No. 4,274,157 disclose a continuous sweat band which is held away from the inside of the hat by means of spacers. U.S. Pat. No. 6,199,214 B1 proposes a headgear ventilation device that attaches to the inside of the headgear by means of pressure sensitive adhesive. Publication No.: US 2012/0278969 A1 discloses a headgear that provides a moisture wicking mechanism, a visor with multiple soft absorbing sections for rapid drainage and evaporation of moisture and a sweatband that secures headgear to wearer's head.

Operation

Presented embodiment of headgear operates as follows. Headgear is held over wearer's head and pushed down until wearer's head fits snugly against ventilated channel support ribs 62 bottom structural arch 58 and rim 50 shown in (FIG. 6 and FIG. 7) Visor 52 protrudes from front of headgear to protect the eyes from direct sun light. Top of headgear ventilation takes effect when ambient air enters through front of headgear via ventilation openings 44 passing through ventilation channels 42 which are divided by support ribs 62 and continues to flow between top structural arch 56 and bottom structural arch 58 and exits through rear ventilation opening 60 as shown in (FIG. 8). This ventilating action within the ventilation channels 42 helps to remove body heat generated by the wearer's head and replacing it with fresh air. In addition insulated ventilation channels 42 protect the wearer's head from external heat sources by reducing the thermal effect of direct sun light. Set between headgear and wearer's head is positioned fabric mesh 76 that covers ventilation channels 42 to keep wearer's hair from blocking air flow as shown in (FIG. 15) On sides of headgear insulated side walls 46 help regulate temperature from external heat sources like sun light and have ventilation openings 48 that allow air to flow removing additional body heat as shown in (FIG. 1) Embedded along inner side area of rim 50 is rim embedded perspiration and moisture drainage channel 66 with perspiration and moisture collection holes 64 and perspiration and moisture drainage discharge holes 68 shown in (FIG. 9A and FIG. 12). To collect perspiration and moisture rim embedded drainage channel 66 forms a pressure seal around the wearer's head and face area to capture perspiration and moisture in to collection holes 64 and into drainage channel 66 and out through discharge holes 68. Perspiration and moisture drainage flow is accomplished by the inclination of the headgear as it is placed in the wearer's head at an angle starting above the eyes and downwards towards the rear of neck area. This inclination of the headgear allows perspiration and moisture to flow by force of gravity towards the perspiration and moisture discharge holes 68 which are located at each end of the perspiration and moisture drainage channel 66 shown in (FIG. 3 and FIG. 11) causing perspiration and moisture to flow along the back sides of the wearer's neck. The amount of perspiration and moisture flow can be regulated with the rim adjustment strap 54 shown in (FIG. 4 and FIG. 14) and accomplished by increasing or decreasing the tension around the rim 50 which will expand or contract the aperture on perspiration and moisture drainage channel 66.

Fabric mesh is placed over front ventilation openings 44 to keep insects from entering ventilation channels 42 as shown in (FIG. 13) Fabric mesh 72 is placed over rear ventilation opening 60 to keep insects from entering ventilation channels 42 as shown in (FIG. 14) Fabric mesh 74 is placed on side ventilation holes 48 to keep insects away from sides of wearer's head as shown in (FIG. 14)

In addition rear ventilation opening can be one or more, and can be closed with a foam plug to stop air flow and retain the heat within the headgear under cold weather conditions.
  • Top and bottom structural arches can be wider or narrower, longer or shorter to aid in the support of the rest of the components within the headgear. In addition top and bottom arches can be made of foam or plastic of different levels of stiffness.
  • Perspiration and moisture collection holes can be larger or smaller and of different shapes and in different quantities.
  • Perspiration and moisture drainage channel can be wider or narrower, thicker or thinner, higher or lower, oval, round or rectangular in shape and made of different materials of harder or softer composition.
