This disclosure relates generally to various embodiments of a camping pad that may be a layered camping pad or hybrid camping pad, or hybrid pad. More specifically it relates to a camping mattress or pad that may comprise an inflatable frame that may incorporate a cushion-like layer, such as a sheet of foam, for additional support and comfort. The features disclosed herein are numerous in nature and may be employed in various different ways to provide the same or similar results.
When camping, a lightweight pad or mattress is typically used under a sleeping bag. Camping pads may provide support padding, and even some insulation for the user. Camping pads have typically fallen into two general categories: inflatable and not inflatable.
Camping pads that are not inflatable are essentially closed-cell strips of foam of a predetermined size. Such pads tend to be heavier than inflatable types. They may be used in any camping situation.
With respect to inflatable camping pads, there are two basic types of pads, both of which rely on a quantity of air for inflation during use and which deflate for portage.
A first, and generally older type of inflatable camping pad, is essentially an inflatable air mattress. A fill valve is opened and air is forced in under positive pressure by mouth, typically, to inflate the camping pad a desired amount.
A second, and generally newer type of camping pad, is a variation of the prior type. The second type may include an open-cell expandable type of foam filler within the open-cell. When a fill valve for such a type of camping pad is opened, the compressed foam (from the deflated state) within the open-cell of the camping pad begins to expand and naturally inflates the mattress. The camping pads that include the foam within the open-cell of the camping pads are generally regarded as being of superior design because they self-inflate (to a certain extent) and are therefore easier to use. They also tend to be warmer and therefore, more comfortable.
While these and perhaps other types of camping pads or mattresses have been used for a long time, they have certain disadvantages when used for camping. For example, virtually all campers are aware of the rarity of level, smooth ground. In addition, the ground tends to act as a heat sink that can rob the sleeper of valuable body heat, which can cause campers to be cold while sleeping on the ground.
This disclosure relates to a padded sleeping system that comprises: an inflatable frame comprising a first sheet of material joined to a second sheet of material at a plurality of bond lines to form an air inflatable support member. The padded sleeping system may further comprise at least one valve that is coupled to the inflatable frame, which is in fluid connection with the air inflatable support member for inflation and deflation of the inflatable frame. The system may also comprise a cushion portion that may be fixed to the inflatable frame.
The air inflatable support member may further comprise multiple fluidly connected air inflatable support members, which may be defined by additional bond lines between the first sheet of material and the second sheet of material. These air inflatable support members may form linear cells that vary in size and shape based on their position relative to the cushion portion of the sleeping pad. Each of the air inflatable support members may alternatively form a cell or baffle that varies in size and shape based on its position with respect to where the user would place certain body parts when laying upon the padded sleeping system.
The cushion portion of the padded sleeping system may comprise a sheet of perforated open cell polyurethane foam having a width that conforms to a width of the inflatable frame and a length that is shorter than a length of the inflatable frame. In such an embodiment, the cushion portion may be fixed to a portion of the inflatable frame.
In a different embodiments, the cushion portion may comprise a plurality of cushion portions that vary in size and shape and are fixed to the inflatable frame at different positions.
In yet another embodiment, the cushion portion may comprise a plurality of individual cells filled with at least one of: foam, feathers, or cotton, or synthetic fiber. Additionally, the cushion material may include a mylar or heat reflective material, closed cell foam, synthetic fiber or any combination thereof.

Referring to
The plurality of fluidly coupled cells 112 may take various different forms, shapes and sizes. In
The plurality of fluidly coupled cells 112 may be formed in various different ways, by way of example, by incorporating various different patterns of bond lines 113 between the first sheet of material 124 and the second sheet of material 126. The bond lines 113 may be formed from welding the first sheet of material and second sheet of material to each other in a predetermined pattern. Alternatively, the bond lines 113 may be tethered from the first sheet of material 124 to the second sheet of material 126 through an I-beam weld wherein the bond lines 113 on each side of the first material and second material are not actually adjacent but are connected via an I-beam weld. In addition, the plurality of fluidly coupled cells 112 may also be formed as a result of the shape and contours of the first and second sheets of material that were joined together to create the inflatable frame 102.
Other embodiments of the inflatable frame 102 may further comprise various non-supporting regions, which may be defined by additional bond lines as set forth in U.S. Pat. No. 9,756,955.
The camping pad 100 may also comprise a cushion portion 114 positioned at the superior portion 101, which may provide additional comfort and support for users laying upon the camping pad 100. The cushion portion 114 may be made out of a variety of different padding materials, such as foam. More specifically, the cushion portion 114 may comprise a strip of perforated open cell polyurethane foam. The perforated nature of the foam may provide the camping pad 100 with greater flexibility, and it may also allow the camping pad to maintain a lighter weight. These features may allow for easier storage and portage. It may also improve the breathability of the camping pad 100, which may be useful when camping in warmer conditions. The cushion portion 114 may also comprise a cushion fabric sleeve 122 (see
The cushion portion 114 may be separate from the inflatable frame 102. That is, the inflatable frame 102 and the cushion portion 114 may be attached, but not in fluid connection. In many prior art camping pads, the cushion is provided within the inflatable portion. A separation of the cushion portion 114 and the inflatable frame 102 may allow the padding or cushioning material to disperse better compared to cushioning material within an inflating portion. This may provide for additional support and comfort of a user.
The cushion portion 114 may take various different forms and be made of various different types of materials. For example, another embodiment of the cushion portion 114 may comprise a plurality of cells, which may be filled with a combination of at least one of the following: synthetic fibers, foam, soft feathers (e.g. down feathers), cotton, closed cell foam, heat reflective material or any combination thereof, or any other materials used in conjunction with mattresses or pillows. Depending on the material that the cushion portion 114 is made out of (such as unperforated foam or down feathers), the cushion portion 114 may provide a user with additional insulation, which may be useful when camping in colder conditions.
The cushion portion 114 may be incorporated into the camping pad 100 in various different ways.
In other configurations, the cushion portion 114 may not in effect replace part of the top portion 110, but rather may be added on top of the top portion 110. In such configurations, the superior portion 101 may have a taller height than the inferior portion 105 of the inflatable frame 102 such that the top of the cushion portion 114 of the superior portion 101 extends above a height of the inflatable frame 102 of the inferior portion 105. The inflatable top portion 117 and cushion top portion 115 may be substantially parallel plains. The width of the cushion portion 114 may conform substantially to the width of the inflatable frame 102. The portion of the pad 100 with the cushion portion 114 may be thicker than any portion(s) of the pad 100 without the cushion portion 114. In some configurations, the pad 100 may have a uniform thickness because the cushion portion 114 extends the entire length or substantially the entire length between the first end 104 and the second end 106 of the camping pad 100. In other configurations, the thickness of the pad 100 may vary has some portions are provided with a cushion portion 114 and others are not.
The cushion portion 114 may be coupled to the inflatable frame 102 in various different ways, for example, by laser welding, ultrasonic welding, binding tape, an adhesive, by sewing the cushion fabric sleeve 122 (which may be fixed around the cushion portion 114) to the inflatable frame 102 or a combination of these or other means well known in the art. The cushion portion 114 may be attached to the exterior of the inflatable frame 102 such that it is separate from the inflatable frame to provide additional comfort and support to a user apart from the support provided by the inflatable frame 102. In some configurations, the cushion portion 114 may be directly coupled to the inflatable frame 102 and in other configurations a cushion fabric sleeve 122 (see
In some configurations, the first sheet of material 124 forming the top of the inflatable frame 102 may be provided with an appendage 119 for a cushion fabric sleeve to be securely and aesthetically connected to the first sheet of material 124. For example, the appendage 119 may be a pleat or fold in the first sheet of material 124. This fold may be formed in any suitable manner. For example, the first sheet of material 124 may be doubled back on itself and secured in place by gluing, sewing, welding, etc. The appendage 119 need not be formed of the first sheet of material 124, and may also be formed by attaching a second piece of material to the first sheet of material 124, such as by gluing, sewing, welding, etc., the second piece of material to the first sheet of material 124.
The appendage 119 may be used to secure the cushion portion 114 to the exterior top side of the inflatable frame. For example, the cushion portion 114 may be comprised of a cushion fabric sleeve 122 with a cushioning material 123 placed within the cushion fabric sleeve 122. The cushion fabric sleeve 122 may be connected to the inflatable frame on one or more sides. For example, in some configurations the cushion fabric sleeve may be attached to the inflatable frame 102 on four sides, on the first side 108, the fold 119, the second side 109, and the first end 104. The appendage 119 may provide a secure place to attach one side of the cushion fabric sleeve, and may do so in an ascetically pleasing way. By providing a connecting point via the appendage 119, the cushion fabric sleeve 122 may be securely attached to the first sheet of material 124 over the appendage 119, covering all or substantially all of the appendage 119, without the need for an exterior connection or cover.
The cushion portion 114 may be incorporated into the camping pad 100 in various different ways. The cushion portion 114 may also form various different shapes and sizes, which may or may not conform to the shape and size of the inflatable frame 102. By way of example, on an alternative embodiment of the camping pad 100, the bottom portion 111 and the top portion 110 may both extend the entire length of the camping pad (from the first end 104 to the second end 106). In such an embodiment, the size and shape of the cushion portion 114 may not conform to the contours of the inflatable frame 102. The cushion portion 114 may be coupled to the camping pad 100 in such a way that it may be positioned to cover the entire top portion 110.
The cushion portion 114 may also alternatively comprise a plurality of cushion portions, which may be coupled to, or may replace, certain parts of the top portion 110. In such an embodiment, the plurality of cushion portions may be arranged in such a way that they may provide targeted support to specific parts of a user's body when lying thereon. By way of example, a cushion portion 114 may be positioned at the shoulders and/or hips of a user while the remainder of the pad 100 comprises only the inflatable portions.

Many of the staggered bond lines 113a in
The bottom portion 111 of the camping pad 100 may be entirely an inflatable portion of the inflatable frame 102. The sizes and shapes of the fluidly coupled cells 112 may vary. The superior portion 101 may have fluidly coupled cells 112b that are situated directly adjacent to and beneath the cushion portion 114 of the camping pad 100 may have a narrower width. Fluidly coupled cells 112a of the inferior portion 105 that are not beneath the cushion 114 may have a wider width. The width of the fluidly coupled cells 112a of the inferior portion 105 may be wider in width than the fluidly coupled cells 112b of the superior portion 101. The fluidly coupled cells 112b of the superior portion 101 that are situated beneath the cushion portion 114 may provide the inflatable frame 102 with a more condensed volume of air providing stiffer structural support for the cushion 114. The fluidly coupled cells 112b of the superior portion 101 may also facilitate greater surface area for adhering the cushion portion 114 to the inflatable portion 102.

Various additional layers may be included in the camping pad 100 to provide insulation as may be desired. Similarly, various materials may be used to form the layers depending on the purpose of use for the camping pad. In some configurations, the inflatable portion may include insulation and/or foam. Mylar may be included in one or more layers or as a fabric layer. The fabric sleeve 122 may be formed of any suitable material, and if desired may be formed from a material with a soft hand-feel such as a micro fleece fabric, etc. In the alternate camping pad 100′ configuration shown in
An individual may use the camping pad 100 in conjunction with various camping activities. For example, the individual may inflate the inflatable frame 102 of the camping pad 100 by engaging either of the first valve 120a (by blowing into the first valve 120a with his or her mouth) or the second valve 120b (by connecting a pump to the second valve 120b). The individual may then place the camping pad 100 beneath the individual's sleeping bag or other sleeping gear and lay on the camping pad 100 for leisure or sleep. Utilizing the camping pad 100 in this manner may provide numerous benefits, including but not limited to, elevating the individual off the ground for insulation purposes and providing the individual with additional comfort while sitting or lying upon the camping pad 100 when the individual is engaged in activities such as camping trips.
When the individual is finished using the camping pad 100, the individual may then deflate the inflatable frame 102 of the camping pad 100 by opening up either of the first valve 120a or the second valve 120b to let the air escape. The individual may desire to introduce pressure to the camping pad 100 in order to drive the air out of the inflatable frame 102. Once the air is driven from within the inflatable frame 102, the individual may desire to store the camping pad 100 by folding it up, rolling it up, or otherwise compressing it into a more portable shape and size.
