[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] Backpacks are among some of the most widely used items for many individuals across all walks of life. In this regard, everyone from athletes to students and even professionals utilize backpacks routinely when they need to transport any number of different items. In general, backpacks typically include a main body having an enclosed storage space where any number of items may be located. A pair of shoulder straps typically extend from the back surface of the main body for permitting a user to secure the backpack onto their back, and any number of individual pockets may be provided along or within the backpack body.

[0004] In many instances, backpacks are constructed from rugged malleable materials that are water resistant in order to protect the items stored within from becoming wet. Additionally, these backpacks are often lined with padding or other such material to protect the stored objects from becoming damaged from impacts with foreign objects. Although these features work well for their intended purpose, one common downside is the amount of heat that builds up on a user's back and shoulder due to the lack of airflow when wearing the backpack for extended periods of time.

[0005] Indeed, this buildup of heat can contribute to users experiencing heat exhaustion along with other acute health conditions, in addition to excessive sweating. As a result, many users must periodically remove their backpack to allow their back, shoulders, and neck to receive fresh air and to cool their body temperature.

[0006] Accordingly, it would be beneficial to provide a backpack with an active ventilation system that can allow users to store and carry any number of different items for any period of time without suffering from the drawbacks noted above.SUMMARY OF THE INVENTION

[0040] In the preferred embodiment, the neck ventilation channel and dispenser will be constructed from a rigid or semi rigid airtight material such as plastic, for example, so as to be able to extend through the first opening 21 of the backpack body in order to dispense air onto the neck of a user wearing the backpack. Of course, other shapes, materials and orientation of components are also contemplated.

[0041] As described herein, each of the shoulder ventilation channels 35 can extend from the top end of the central chamber 32 and can include elongated hollow members having an inlet opening 35a along the bottom end and a plurality of shoulder vents 35b along the length thereof.

[0042] As shown best in FIG. 4, the shoulder ventilation channels will be positioned within the backpack straps 20 and each of the vents 35b will be positioned in line with the holes 25 so as to direct airflow from the ventilation system onto the shoulders and torso section of a user wearing the backpack device. In this regard, it is preferred that the shoulder ventilation channels will be constructed from a malleable airtight material such as rubber hose or plastic-coated nylon fabric, for example, so as to allow a user to easily manipulate the orientation of the backpack straps when wearing the backpack. Of course, other shapes, materials and orientation of components are also contemplated.

[0043] Although described and illustrated with regard to all of the airflow from the fan going directly into the central chamber and then passing to the neck and shoulder channels, many other arrangements are also contemplated. To this end, other embodiments are contemplated wherein each of the central chamber, the neck channel and the shoulder channels are each directly coupled to the air outlet of the fan so as to independently receive airflow from the same. In such an embodiment, an air diverter may be provided to allow a user to adjust the volume of airflow to each of the components. Additionally, other embodiments are contemplated wherein multiple fans are utilized to generate airflow independently or cumulatively to the chamber and channels.
