Ventilation and temperature adjustment opening for outdoor equipment

Abstract

An outdoor item such as a sleeping bag, jacket, hat or blanket with one or more ventilation/temperature adjustment openings. Each ventilation/temperature adjustment opening includes a fastening mechanism that when opened, an opening is formed in the outer layer and insulative material/layer of the sleeping bag but not in the inner layer, allowing the outdoor item to vent better, thereby cooling an occupant using or wearing the outdoor item thereby offering temperature regulation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) The present invention features one or more ventilation/temperature adjustment openings or thermo gills for a piece of outdoor equipment used for covering and providing warmth to a user such as a sleeping bag, jacket or blanket. In a first embodiment of the present invention, first and second thermo-gills or temperature/venting elements 202 are used on a sleeping bag 200, FIGS. 1A and 1B.

(7) In this first embodiment, the sleeping bag 200, which can be any type of sleeping bag, features a length and width, and includes two ventilation or temperature adjustment openings 202a and 202b, which extend along a length of the front or side of the sleeping bag 200. A first ventilation or temperature adjustment opening 202a is located on a first side of a central access opening 204 and a second ventilation or temperature adjustment opening 202b is located on a second side of the central access opening 204. The central access opening 204 is typically a zipper which is utilized to allow the user to enter and exit the sleeping bag 200. Once the user is inside, the zipper is pulled up proximate the head or shoulder region 206 of the user now located inside the sleeping bag as is well known in the art.

(8) Each ventilation or temperature adjustment opening 202 is formed by a two part traditional zipper 208, FIG. 1B, or similar and equivalent closure or fastener mechanism sewed or otherwise adhered to a region proximate the outer layer 216 of the sleeping bag 200 such as a hook and loop closure, a plurality of buttons, and a plurality of snaps. The length of the ventilation or temperature adjustment openings 202 may vary without the departing from the scope and intent of the present invention. For example, the ventilation or temperature adjustment opening 200 may begin near the foot box portion 210 of the sleeping bag 200 and extend anywhere up to and including the shoulder region 212 of the sleeping bag 200. Alternatively, as shown in the drawing, the ventilation or temperature adjustment openings 200 may be located generally in the central or middle region 213 of the sleeping bag which would be in the area of the midsection of the user (not shown) when located inside the sleeping bag.

(9) As shown in FIG. 1B, the sleeping bag consists of an inner material 214 such as 20 denier durable, water repellent nylon which is designed to rest closest to the user; and an outer layer 216 such as 15 denier ripstop, polyurethane coated, water proof and breathable nylon exposed to the air and elements. In one embodiment, the inner material 214 may be different in different parts of the sleeping bag. For example, the foot box portion or lower region 210 of the sleeping bag may have a different inner material such as 33 to 44 denier ripstop nylon that is durable water repellent treated and having a Cire finish that increases shininess.

(10) Between the inner layer 214 and the outer layer 216 is the insulative material 218 which may include but is not limited to down fill; polyester fill or any other type of natural or synthetic insulative material which may be utilized in the construction of a sleeping bag 200 and which gives the sleeping bag its warmth.

(11) When the zipper or other fastening mechanism 208 of the ventilation or temperature adjustment opening 202 is opened, a crevice or generally V shaped opening 220 is formed in the outer layer 216 and the insulative material 218, allowing the sleeping bag to breathe better, thereby cooling an occupant of the sleeping bag and offering temperature regulation. The inner walls 222 of the opening 220 may be formed from the same material as the outer layer 216; the same material as the inner layer 214; or a completely different material, all as selected by the manufacturer of the sleeping bag. The inner layer 214 remains intact to prevent the sleeping bag 200 from dividing into two (2) sections and/or to prevent insects and the like from entering the sleeping bag, garment, blanket or other covering provided with one or more ventilation openings.

(12) The amount of ventilation provided to the user may be adjusted and selected by the user by simply opening or closing more or less of the zipper or other fastener 208, which adjusts the length of the ventilation or temperature adjustment openings 202. In this way, a very insulative sleeping bag designed for cold or very cold weather may be utilized in moderately cold weather without causing the user to overheat in the sleeping bag by simply adjusting the ventilation or temperature control openings 202, thereby eliminating the need for a user to try to accurately predict the temperature where he or she is going and predict which sleeping bag should be used and instead, simply regulate the warmth afforded by the sleeping bag utilizing the temperature or ventilation openings 202 of the present invention to instead regulate the temperature inside the bag. The same holds true for other outdoor coverings such as jackets, blankets and potentially even hats and the like.

(13) The present invention is not limited to providing ventilation or temperature regulating openings in a sleeping bag but may also be utilized in other outdoor equipment such as a jacket or coat 230, FIG. 2 or a blanket, FIG. 3. In much the same way as described in connection with the embodiment covering sleeping bags, the ventilation or temperature regulating openings 232 may be provided and opened or closed to a desired extent by the user to regulate the ventilating action of the openings 232. The ventilation or temperature regulating openings 232 may be located not only in the front of the garment but also in the sleeve (not shown) and also potentially in the back of the garment (also not shown) which other locations are considered to be within the scope of the present disclosure.

(14) In another embodiment, one or more ventilation or temperature regulating openings 252, FIG. 3 may be provided in a blanket 250. Again, although only one opening is shown is considered to be within the scope of the present invention that multiple openings may be provided in multiple regions of the blanket 250.

(15) As stated above, the present invention is not intended to be limited to a device or method which must satisfy one or more of any stated or implied objects or features of the invention and should not be limited to the preferred, exemplary, or primary embodiment(s) described herein. Modifications and substitutions by one of ordinary skill in the art are considered to be within the scope of the present invention, which is not to be limited except by the allowed claims and their legal equivalents.
