Description:

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to wader, and more particularly to wader comprising an air ventilation arrangement which is capable of enhancing air circulation on a wearer's skin.

2. Description of Related Arts

A conventional wader comprises a wader body shaped and sized to be worn on a wearer's body for the wearer to perform fly-fishing or any other activities which require the wearer to immerse into water for a prolonged period of time. A conventional wader body usually comprises an inner layer, a middle layer having an inner side attached on the inner layer, and an outer layer attached on an outer side of the middle layer to form a waterproof wader body. More particularly, one or more of the three layers may be made of heat insulation materials such that the wader body can also protect the wearer from losing heat.

A major disadvantage of the above-mentioned conventional wader is that when the wanders body is elastic in property and is usually designed to have tight contact with the wearer's body. As a result, the wearer may feel uncomfortable and difficult to have body movement when he or she wears the wanders for an extended period of time.

As a matter of fact, the wanders body may be designed to be looser so that the inner layer will not tightly attached to the wearer's skin. However, the problem with this possible design is that if the wanders is made to be loose, the heat insulation ability of the wader may be severely affected so as to render the entire wader not suitable for use in certain circumstances.

It is worth mentioning that there exits sophisticatedly developed composites materials which is capable of allowing passage of air and at the same time waterproofing. As a result, the wearer's skin will have adequate ventilation while the materials itself is still waterproof. This kind of composites materials is supreme in quality and optimal for fabricating wader. However, the major problem is that this kind of materials is very expensive so that it has not become popular among wader' users.

SUMMARY OF THE PRESENT INVENTION

A main object of the present invention is to provide wader comprising an air ventilation arrangement which is capable of enhancing air circulation on a wearer's skin while maintaining sound waterproof and heat insulating capability.

Another object of the present invention is to provide wader comprising an air ventilation arrangement, which is adapted to facilitate comfort and easy movement of a wearer when he or she is wearing the wader.

Another object of the present invention is to provide wader comprising an air ventilation arrangement, wherein the wader are capable of serving a wide variety of purposes so as to facilitate widespread application of the present invention.

Another object of the present invention is to provide wanders comprising an air ventilation arrangement, which does not involve any complicated or expensive mechanical components so as to minimize the manufacturing cost as well as the ultimate selling price of the present invention.

Accordingly, in order to accomplish the above objects, the present invention provides a wader, comprising:

a wader body shaped and sized for a wearer being fittingly worn, wherein the wanders body comprises a waterproof outer layer, an inner lining, and a heat insulating layer affixed between the outer layer and the inner lining; and

air ventilation arrangement which contains a plurality of air ventilating channels indently formed on the inner lining of the wanders body for allowing air to circulate within the wanders body through the air ventilating channels so as to provide adequate air ventilation to the wearer's body when the wanders body is tightly worn.

These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1 to FIG. 2 of the drawings, a wader according to a preferred embodiment of the present invention is illustrated, in which the wader comprises a wader body 10, and an air ventilation arrangement 20.

The wader body 10 is shaped and sized for a wearer being fittingly worn, wherein the wader body 10 comprises a waterproof outer layer 11, an inner lining 12, and a heat insulating layer 13 affixed between the outer layer 11 and the inner lining 12.

The air ventilation arrangement 20 contains a plurality of air ventilating channels 21 indently formed on the inner lining 12 of the wader body 10 for allowing air to circulate within the wader body 10 through the air ventilating channels 21 so as to provide adequate air ventilation to a lower body portion of the wearer's body 10 when the wader body 10 is worn (perhaps tightly worn). It is worth mentioning that the lower body portion of the wearer's body is those part of the body which immerse into the water (i.e. below water level) when the wearer uses the present invention for, say, fishing. On the contrary, an upper body portion of the wearer is those part of the body which is above the water level when the wearer wears on the wader of the present invention. As such, the lower portion of the wearer's body will subject to water pressure which tends to press the wader against the lower portion of the wearer's body.

According to the preferred embodiment of the present invention, the wader body 10 is shaped and sized to have two leg portions 14, a waist portion 15 upwardly extended from an upper end of the leg portions 14 for wearing on the wearer's waist, and two enclosed foot portions 16 provided at lower ends of the leg portions 14 for sealingly receiving the wearer's foots respectively. In other words, when the wearer wears the wader of the present invention, his or her waist, legs and foots are isolated and protected from external environment.

In other words, the wader body 10 has an upper opening portion (comprising the waist portion 15) and two bottom enclosed portions (comprising the two leg portions 14 and the two enclosed foot portions 16) extended therefrom, wherein the air ventilating channels 21 are formed on the inner lining 12 and extended from the upper opening portion of the wader body 10 to the enclosed portions thereof in such a manner that the wader body 10 enhances air circulation within the enclosed portions through the air ventilating channels 21 during body movement of the wearer.

It is worth mentioning that in order to achieve the weatherproof and heat insulation capabilities of the wader, the heat insulating layer 13 is preferably embodied as being manufactured by neoprene which is a synthetic polymer resembling rubber, and is resistant to oil, heat, and weathering. On the other hand, the waterproof outer layer 11 is preferably embodied as waterproof fabric such as nylon which is capable of blocking water from penetrating through the waterproof outer layer 11. The inner lining layer 12 is also preferably embodied as weatherproof fabric (such as nylon) which is capable of resisting environmental adverse effect as well as imparting optimal comfort to the wearer of the wader by its inherent elasticity.

The air ventilation arrangement 20 further comprises an air retention rim 22 provided along the top edge of the waist portion 15 of the wader body 10, wherein the air retention rim 22 has an air receiving cavity 23 formed therein to communicate with the air ventilating channels 21 extended along the inner lining 12 of the wader body 10 in such a manner that air within the air receiving cavity 23 is allowed to circulate in the air ventilating channels 21 for providing adequate air ventilation for the wearer. In other words, circulation of air between the air ventilating channels 21 is made possible via the air retention rim 22.

Referring to FIG. 2 of the drawings, the air ventilating channels 21 are extended along the inner lining 12 of the wader body 10 in a cross manner so that each of the air ventilating channels 21 is arranged to intersect with at least one of the other air ventilating channels 21 for forming an air ventilating network on the inner lining 12 of the wader body 10.

It is worth mentioning that the air ventilating channels 21 may alternatively be extended along the inner lining 12 in a substantially parallel manner so that each of the air ventilating channels 21 does not intersect with each other, as shown in FIG. 3 of the drawings. This alternative arrangement has the advantage of evenly distributing air ventilation along the inner lining 12 so as to maximize the wearer's comfort. Moreover, as shown in FIG. 4 of the drawings, the air ventilating channels 21 may also be formed by a plurality of aesthetical patterns indently formed on the inner lining 12 of the wader body 10.

The waterproof outer layer 11, the inner lining 12 and the heat insulating layer 13 are preferably embodied as having a predetermined elasticity so as to normally tighten against the wearer's skin. However, the air ventilating channels 21 and the air retention rim 22 are then capable of allowing air ventilating on the wearer's skin so as to overcome the disadvantages of conventional wader as mentioned above.

The operation of the present invention is as follows: when the wearer wears on the wader of the present invention, the wearer's foots, legs, and waist are enclosed by the foot portions 16, the leg portions 14 and the waist portion 15 of the wader body 10 for isolating the wearer's foots, legs and waist from ambient environment. The inner lining 12 has a predetermined elasticity so that the wearer's foots, legs and waist are fittedly enclosed by the inner lining 12. At the same time, the air ventilating channels 21 are arranged to allow air circulating on the wearer's skin so as to impart the wearer with maximum comfort while not affecting any protective function (e.g. heat insulating or waterproof capability) of the wader of the present invention.

It is important to point out that the present invention is extremely easy to manufacture, so that the manufacturing cost of the present invention can be minimized. Moreover, the wader of the present invention are universal in the sense that they may fit for persons of different height, weight and genders. Consequently, widespread application of the present invention can be foreseen.

One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.

It will thus be seen that the objects of the present invention have been fully and effectively accomplished. Its embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
