Description

FIELD OF THE INVENTION

The presently disclosed subject matter relates generally to airbed systems, particularly internal tensioning structures for airbeds.

BACKGROUND

Conventional airbeds, or air mattresses, as they are commonly referred, are typically used in lieu of traditional box-spring mattresses, memory foam mattresses, water beds, and other beds as temporary structures for sleeping. Generally, air mattresses comprise a soft and flexible material chamber with an air-tight seal that allows the air mattress to inflate during use and deflate after use. While some air mattresses must be manually inflated by the human user, many air mattresses include a manual or an electric pump to enable mechanical inflation. Airbeds typically comprise an internal structure or tensioning structure that helps the airbed achieve its intended shape once the airbed is inflated. The internal structure also prevents the airbed from over-inflating. In some conventional airbeds, the internal structure comprises a plurality of strips with each strip comprising several strands of string or wire. In some cases, however, the internal structure can add to the airbed's overall weight and rigid components can make the airbed cumbersome to fold up and store when not inflated. And in other cases, the internal structure does not provide a desired appearance of the airbed.
Accordingly, there is a need for improved systems and methods to address the above mentioned deficiencies. Embodiments of the present disclosure are directed to these and other considerations.
US patent application publication no. US2014/265485 describes an inflatable device that includes an upper layer, a lower layer, and at least one strap alternately connected to the upper layer and the lower layer to form a wavelike pattern between the upper layer and the lower layer so as to limit deformation of both the upper layer and the lower layer. The strap includes a plurality of first contact portions connected to the upper layer, and a plurality of second contact portions connected to the lower layer. The first contact portions are offset from the second contact portions in a horizontal plane respectively defined by the upper layer and the lower layer, such that the first contact portions are not superimposed with the second contact portions from a perspective orthogonal to the upper and lower layers.
US2015/113736 describes inflatable mattresses in the form of beds, chairs, couches, or other gas-inflatable structures. The mattress has an internal support structure with one or more diagonal structural support elements comprised of rigid or flexible cords or cables that are coupled to the top, bottom, and/or sides of the air mattress.

SUMMARY

In accordance with the present invention, there is provided an inflatable air mattress as recited in the accompanying claims.
Briefly described, embodiments of the presently disclosed subject matter relate to airbed systems and, in particular, airbed systems having improved tensioning structures such as a sheet-based internal structure or strip-based internal structures.
Aspects of the present disclosure relate to internal structures for air mattresses. In particular, certain aspects of the present disclosure relate to an internal structure comprising a sheet connected to the interior surfaces of the top and bottom surfaces of an air mattress.
According to some examples not forming part of the invention, the sheet may comprise a single piece of material having a plurality of apertures, forming a mesh (which may be referred to as a "mesh sheet" or "mesh web"). Each of the top and bottom surfaces may comprise a plurality of connection points, and the sheet may be attached to two or more top surface connection points and two or more bottom surface connection points. The sheet may be attached to the top surface and bottom surface in such a manner that it forms a web-like structure or a wavy 3-dimensional sinusoidal shape when the airbed is inflated. The internal structure may help the air mattress maintain its intended geometric shape when inflated. Further, the internal structure may prevent the air mattress from becoming over-inflated. Also, the internal structure may prevent the top and bottom surfaces of the air mattress from shearing (i.e., moving laterally relative to one another) when the air mattress is in use. Also, because such an internal structure is light-weight and adds little to the overall bulk of the air mattress, when deflated, the air mattress can be easily stowed away and transported.
The embodiments of the present invention relate to internal structures comprising a plurality of connection strips connected to the interior surfaces of the top and bottom surfaces of an air mattress. Each of the top and bottom surfaces comprises a plurality of connection points, and the connection strips attach to the surfaces at those connection points. According to the invention, multiple connection strips may attach to a single connection point. Further, connection strips may angle from one connection point on the bottom surface toward another connection point on the top surface. In such a configuration, the plurality of connection strips constitute an internal structure that is configured like a web. The web-like internal structure may help the air mattress maintain its intended geometric shape when inflated and provide other such benefits as described above with respect to the internal structure comprising a sheet
The foregoing summarizes only a few aspects of the presently disclosed subject matter and is not intended to be reflective of the full scope of the presently disclosed subject matter as claimed. Additional features and advantages of the presently disclosed subject matter are set forth in the following description, may be apparent from the description, or may be learned by practicing the presently disclosed subject matter.

Such other components not described herein can include, but are not limited to, for example, similar components that are developed after development of the presently disclosed subject matter.
The present disclosure is described in reference to an internal structure for an air mattress or airbed. In particular, the present disclosure relates to an internal structure that comprises a sheet or a plurality of connection strips that attach to connection points on the top and bottom surfaces of an air mattress. The sheet or connection strips may angle from one connection point (e.g., on the bottom surface) toward another connection point (e.g., on the top surface). A single sheet can be attached to a plurality of connection points, creating an internal structure having a web-like effect. According to the invention, multiple connection strips attach to a single connection point, thus creating an internal structure having a web-like effect. An internal structure having such a web-like configuration not only helps the air mattress maintain its intended shape and prevents over-inflation, it prevents the top and bottom surfaces from shearing or moving laterally relative to one another. Further, because such an internal structure is light-weight and comprises minimal material, it allows the air mattress to be easily stowed and transported.
Referring now to the figures, wherein like reference numerals represent like parts throughout the views, embodiments of the internal airbed structure will be described in detail.
FIG. 1 is an overview of an air mattress 100. Air mattress 100 may vary in size once inflated based on the desired dimensions and/or number of users. For example, air mattress 100 may be a twin, full, queen, or king size bed. In some embodiments, air mattress 100 may be constructed out of polyvinyl chloride ("PVC"). It is contemplated, however, that other materials such as other plastics or rubber may be used. Further, as shown in FIG. 1, the air mattress 100 may comprise a top surface 110 and bottom surface 115 as well as side surfaces (e.g., side surface 120).
FIG. 2 is a top view of an embodiment of an air mattress 100 comprising an internal structure 200. As discussed, in some embodiments, an internal structure 200 of an air mattress 100 may be included in the interior of the air mattress 100. The internal structure 200 may help the air mattress 100 achieve and maintain its intended shape once the air mattress 100 is inflated. Further, an internal structure 200 may prevent the air mattress 100 from over-inflating. Similarly, the internal structure 200 may prevent the top surface (e.g., top surface 110) and the bottom surface (e.g., bottom surface 115) from shearing (i.e., moving laterally relative to each other).
According to the invention, an internal structure 200 comprises a plurality of connection strips 210 (e.g., strips 210a, 210b) having a predetermined length that are attached (i.e., joined, connected, affixed) to one or more of the top surface 110 and bottom surface 115 of the air mattress 100. In some embodiments, a connection strip 210 may be constructed from PVC or various other fiber, fabric, or film that is suitable for a particular application. In some embodiments, a connection strip 210 may be constructed from a single piece of material (e.g., the connection strip 210 may be a single, continuous strip of PVC). In some embodiments, a connection strip 210 may be constructed from a collection (i.e., a plurality) of materials, fibers, or strings.
As shown in FIG. 2, in some embodiments, the air mattress 100 can be transparent, thereby providing a view of the plurality of connection strips 210 (e.g., connection strips 210a, 210b) comprising the internal structure 200. Further, the transparency of the air mattress 100 provides a view of top surface connection points 215, as highlighted by dashed box 220, which includes top surface connection point 215a. Further, the transparency of the air mattress 100 provides a view of bottom surface connection points 225, as highlighted by dashed box 230, which includes bottom surface connection point 225a. According to the invention, connection points (e.g., top surface connection points 215 and bottom surface connection points 225) are on opposing interior surfaces of the top surface 110 and bottom surface 115. Accordingly, the connection points are on the interior of the air mattress 100. Further, in some embodiments, connection strips 210 may attach directly to connection points 215 and 225. In some embodiments, for example, a connection strip 210 may be welded to top and bottom surface attachment points 215, 225. Further, in some embodiments, a connection strip 210 may be glued, sewn, adhered, or otherwise attached to top and bottom surface attachment points 215, 225.
As shown in FIG. 2, according to the invention, a connection strip 210 attaches between a top surface connection point 215 and a bottom surface connection point 225. In some embodiments, when an air mattress 100 is inflated, as shown in FIG. 2, a connection strip 210 may angle from top surface 110 toward bottom surface 115, or vice versa. For example, as shown in FIG. 2, connection strip 210c angles from bottom surface connection point 225b toward top surface connection point 215a. Similarly, as shown in FIG. 2, connection strip 210d angles from bottom surface connection point 225a toward top surface connection point 215b, according to some embodiments. As will be appreciated, when configured in the manner described and shown in FIG. 2, angled connection strips (e.g., connection strip 210c and 210d) may comprise an internal structure 200 with sufficient strength to prevent the air mattress 100 from over-inflating and to prevent the top surface and bottom surface (e.g., 110 and 115) from moving laterally in relation to one another (i.e., shearing).
Further, according to the invention, a plurality of connection strips 210 connects to a particular top surface connection point 215 or bottom surface connection point 225. For example, in some embodiments and as shown in FIG. 2, four connection strips 210e-h attach to a single connection point (i.e., top surface connection point 215c). According to the invention, three or more connection strips 210 connect to a particular connection point (e.g., a top surface connection point 215 or bottom surface connection point 225. As shown in FIG. 2, in configurations in which multiple connection strips (e.g., 210e-h) attach to a single connection point (e.g., top surface connection point 215c), and in which the connection strips 210 angle from a top surface connection points 215 toward bottom surface connection points 225, and vice versa, the plurality of connection strips 210 may constitute an internal structure 200 having a web-like configuration. According to some embodiments, a plurality of top surface connection points 215 may be spaced apart at predetermined distances or intervals, and a plurality of bottom surface connection points may also be spaced apart at predetermined distances or intervals. According to the invention, a plurality of bottom surface connection points 225 is located on the bottom surface 115 in positions that are offset relative to the locations of the plurality of top surface connection points 215 on the top surface 110. As will be appreciated, an internal structure 200 having a web-like configuration may further aid in helping an air mattress 100 maintain its intended shape and prevent the air mattress 100 from becoming over-inflated. Further, an internal structure 200 having a web-like configuration may help prevent the top surface 110 and bottom surface 115 of an air mattress 100 from shearing or moving laterally relative to one another.
As noted above, in some embodiments, a connection strip 210 may be constructed from a single piece of material. But, in some embodiments, a connection strip 210 may comprise a plurality of individual strips or strands. In some embodiments, each of the plurality of individual strips that comprise a connection strip may attach to the same top surface connection point 215 and bottom surface connection point 225. In some embodiments, however, a connection strip 210 may comprise attachment strips (or, alternatively, weld strips) at each end of the connection strip 210. An attachment strip may be a strip of material or a patch, that may be used to affix a portion of an internal structure 200 to a portion of the air mattress 100. For example, an attachment strip may be a strip of PVC that may be welded to a surface of the air mattress 100. In some embodiments, a portion of an internal structure 200, for example, a portion of a connection strip 210, may be sandwiched between an attachment strip and a surface of the air mattress 100 and the attachment strip may be welded to the surface of the air mattress 100 to secure the connection strip 210 to it. In such embodiments, the plurality of individual strips or strands comprising the connection strip 210 may be held in place by the opposing attachment strips, and the attachment strips may be affixed to the top and bottom surface connection points (i.e., 215 and 225). For example, in some embodiments, an attachment strip, a portion of a connection strip 210, and a portion of either the top surface 110 or bottom surface 115 may be welded together at a top surface connection point 215 or bottom surface connection point 225.
FIG. 3A is a side view of an air mattress 100, according to some embodiments. As shown in FIG. 3A, a top surface 110 comprises a plurality of top surface connection points 315a, 315b as well as a plurality of bottom surface connection points 325a, 325b. A connection strip (e.g., connection strip 315a) connects at two connection points (e.g., top surface connection point 315a and bottom surface connection point 325a). As shown in FIG. 3A, in some embodiments, a connection strip 310a may angle from a top surface connection point (e.g., 315a) toward a bottom surface connection point (e.g., 325a). Similarly, in some embodiments, a connection strip 310b may angle from a bottom surface connection point 325b toward a top surface connection point 315b. As will be appreciated, such a configuration of connection strips (e.g., 310a, 310b) creates a web-like internal structure 200, which may help prevent the top surface 110 and bottom surface 115 of the mattress 100 from shearing.
Similarly, FIG. 3B is an end view of an air mattress 100, according to some embodiments. As shown in FIG. 3B, according to the invention, a top surface 110 comprises a plurality of top surface connection points (e.g., 315c), and a bottom surface 115 comprises a plurality of bottom surface connection points (e.g., 325c), and connection strips (e.g., 310c) being attached therebetween.
FIG. 4 is a perspective view of an air mattress 100, according to some embodiments. As shown in FIG. 4, the air mattress 100 is transparent (as in FIG. 2), thereby providing a view of the plurality of connection strips (e.g., 410a, 410b, 410c) comprising the internal structure. Further, FIG. 4 includes a close-up view 4A of various components of the internal structure, according to some embodiments. For example, close-up view 4A highlights top surface connection point 415a and bottom surface connection points 425a and 425b. Further, close-up view 4A highlights connection strip 410b, which is attached to top surface connection point 415a and bottom surface connection point 425a. Further, close-up view 4A highlights connection strip 410c, which is attached to top surface connection point 415a and bottom surface connection point 425b. As shown in FIG. 4, in some embodiments, one or more connections strips 410 may be configured to extend from a top surface connection point 415 to a bottom surface connection point 425 at a non-right angle. Further, a plurality of connection strips 410 extends out of each of the top surface connection points 415 and bottom surface connection points 425 to the opposing surface. According to the invention, a connection point has three, four, or more connection strips 410 extending away from it. According to some embodiments, each of these connection strips 410 may extend and connect to a different connection point on the opposing surface. The opposing surface of the top surface connection points 415 may be the bottom surface 115 and the opposing surface of the bottom surface connection points 425 may be the top surface 110. According to the invention, where a connection point has a plurality of connection strips 410 extending out of it, the plurality of connection strips may be configured to extend away from the connection point such that they are approximately equidistant from each adjacent connection strip 410 when the mattress is inflated.
FIG. 5 is a perspective view of an air mattress 100 comprising an internal structure 500. In some embodiments, an internal structure 500 of an air mattress 100 may be included in the interior of the air mattress 100 and may operate in a manner similar to internal structure 200 described above. For example, the internal structure 500 may help the air mattress 100 achieve and maintain its intended shape once the air mattress 100 is inflated. Further, internal structure 500 may prevent the air mattress from over-inflating. Similarly, the internal structure 500 may prevent the top surface (e.g., top surface 110) and the bottom surface (e.g., bottom surface 115) from shearing (i.e., moving laterally relative to each other).
According to the invention, an internal structure 500 comprises a plurality of connection strips 510 having a predetermined length that are attached (i.e., joined, connected, affixed) to the top surface 110 and bottom surface 115 of the air mattress 100. In some embodiments, a connection strip 510 may be constructed from PVC or various other fiber, fabric, or film that is suitable for a particular application. In some embodiments, a connection strip 510 may be mesh, thread, or an equivalent material. A connection strip 510 may be constructed from a single piece of material (e.g., the connection strip 510 may be a single, continuous strip of PVC, mesh, thread, or an equivalent material), or a connection strip 510 may be constructed from a collection (i.e., a plurality) of materials, fibers, or strings. According to some embodiments, a connection strip 610 may be attached to the top surface 110 and/or bottom surface 115 at the top surface connection point 615 and/or bottom surface connection point 525, respectively, by positioning the top surface connection point 515 and/or bottom surface connection point 525 between an internal surface of air mattress 100 and a PVC strip and welding them together.
As described above, in some embodiments, the air mattress 100 can be transparent, thereby providing a view of the plurality of connection strips 510 comprising internal structure 500. Further, the transparency of the air mattress 100 provides a view of top surface connection points 515, which includes top surface connection point 515a. Further, the transparency of the air mattress 100 provides a view of bottom surface connection points 525, which includes bottom surface connection point 525a. Connection points (e.g., top surface connection points 515 and bottom surface connection points 525) are on opposing interior surfaces of the top surface 110 and bottom surface 115. Accordingly, the connection points are on the interior of the air mattress 100. Further, in some embodiments, connection strips 510 may attach directly to connection points 515 and 525. In some embodiments, for example, a connection strip 610 may be welded to top and bottom surface attachment points 515, 525. Further, in some embodiments, a connection strip 510 may be glued, sewn, adhered, or otherwise attached to top and bottom surface attachment points 515, 525.
As shown in FIG. 5, a connection strip 510 attaches between a top surface connection point 515 and a bottom surface connection point 525. In some embodiments, when air mattress 100 is inflated, a connection strip may angle from top surface 110 toward bottom surface 115, or vice versa, in a "zig-zag" fashion. For example, as shown in FIG. 2, connection strip 510a angles from the bottom surface connection point 525a toward top surface connection point 515a. As shown in FIG. 5, the connection strips 510 connecting bottom surface connection points 525 to top surface connection points 515 may be arranged in rows. For example, in the embodiment shown in FIG. 5, the internal structure 500 is made up of six rows of connection strips 510, wherein each row is indicated by top surface connection points 515a, 515b, 515c, 515d, 515e, and 515f, respectively. According to some embodiments, each row of connection strips 510 may be oriented to run parallel to the length of the air mattress 100. Alternatively, in some embodiments, each row of connection strips 510 may be oriented to run parallel to the width of the air mattress 100. And as a further alternative, rows of connection strips 510 can run in both directions. Although FIG. 2 shows six rows of connection strips 510, it will be understood that an internal structure 500 may be comprised of any number of rows of connection strips 510. As will be appreciated, when configured in the manner described and shown in FIG. 5, the rows of angled connection strips 510 may comprise an internal structure 500 that prevents the air mattress 100 from over-inflating and that prevents the top surface and bottom surface (e.g., 110 and 115) from moving laterally in relation to one another (i.e., shearing).
As noted above, in some embodiments, a connection strip 510 may be constructed from a single piece of material. But, in some embodiments, a connection strip 510 may comprise a plurality of individual strips or strands. In some embodiments, each of the plurality of individual strips that comprise a connection strip may attach to the same top surface connection point 515 and bottom surface connection point 525. In some embodiments, however, a connection strip 510 may comprise attachment strips (or, alternatively, weld strips) at each end of the connection strip 510. In such embodiments, the plurality of individual strips or strands comprising the connection strip 510 may be held in place by the opposing attachment strips, and the attachment strips may be affixed to the top and bottom surface connection points (i.e., 515 and 525).
FIG. 6 is a perspective view of an air mattress 100 comprising an internal structure 700 that is comprised of a single sheet of material. According to some examples not forming part of the invention, the internal structure 700 may be a continuous piece of material. In some examples, the internal structure may be a mesh structure 610 (which may also be referred to as a "mesh web" or a "mesh sheet") that includes one or more apertures forming a mesh. In some examples, a mesh structure 610 may be made of a single piece of material including a plurality of apertures. In some examples, an internal structure 600 of an air mattress 100 may be included in the interior of the air mattress 100 and may operate in a manner similar to internal structures 200, 500 described above. For example, the internal structure 600 may help the air mattress 100 achieve and maintain its intended shape once the air mattress 100 is inflated. Further, internal structure 600 may prevent the air mattress from over-inflating. Similarly, the internal mesh structure 600 may prevent the top surface (e.g., top surface 110) and the bottom surface (e.g., bottom surface 115) from shearing (i.e., moving laterally relative to each other). In some examples, the outer edge of the internal structure 600 may be attached to the inner surfaces of the side surfaces 120.
In some examples, a mesh structure 610 may be constructed from PVC or various other fiber, fabric, or film that is suitable for a particular application. In some examples, a mesh structure 610 may be constructed form a single piece of material (e.g., the mesh structure 610 may be a single, continuous piece of fiber). In some examples, a mesh structure 610 may be constructed from a collection (i.e., plurality) of materials, fibers, or strings.
As shown in FIG. 6, in some examples, a mesh structure 610 may attach to the internal surface of an air mattress 100 at various top surface connection points 615 and bottom surface connection points 625. According to some examples, the top surface connection points 615 and bottom surface connection points 625 may be located in positions similar to those shown with respect to internal structure 200 and creating a 3D web-like structure as previously described above. For example, a plurality of top surface connection points 615 may be spaced apart at predetermined distances or intervals, and a plurality of bottom surface connection points may also be spaced apart at predetermined distances or intervals. In some examples, a plurality of bottom surface connection points 625 may be located on the bottom surface 115 in positions that are offset relative to the locations of the plurality of top surface connection points 615 on the top surface 110. Accordingly, in some examples, when air mattress 100 is inflated, the mesh structure 610 may take on a 3 dimensional, approximately sinusoidal shape with top and bottom "humps" extending in upwards and/or downwards directions when the airbed is inflated, as shown in FIG. 6. According to some examples, the peak of each top hump may attach to the air mattress 100 at a top connection point 615 and the trough of each bottom hump may attach to the air mattress 100 at a bottom connection point 625. As will be appreciated, an internal structure 600 having a web-like configuration may help prevent the top surface 110 and bottom surface 115 of an air mattress 100 from shearing and moving laterally relative to one another.
As described above, a mesh structure 610 may attach (i.e., join, connect, affix) to the top surface 110 and bottom surface 115 of the air mattress 100. In some examples, a mesh structure 610 may attach to the air mattress 100 at one or more top surface connection points 615 and one or more bottom surface connection points 625. In some examples, portions of a mesh structure 610 may be welded to top and bottom surface attachment points 615, 625. In some examples, portions of the mesh structure 610 may be attached to the air mattress 100 with one or more attachment strips. For example, an attachment strip may be used to secure a portion of a mesh structure 610 to a top surface connection point 615 or a bottom surface connection point 625. As shown in FIG. 7, according to some examples, portions of the mesh structure 610 may be attached to the air mattress 100 with one or more attachment strips 705. For example, a top connection point 615 may be sandwiched between an attachment strip 705 and the top surface 110 and the three may be welded together. Likewise, a bottom surface connection point 625 may be sandwiched between an attachment strip 705 and the bottom surface 115 and the three may be welded together. According to some examples, an attachment strip 705 may be a PVC strip. Further, in some examples, a mesh structure 610 may be glued, sewn, adhered, or otherwise attached to top and bottom surface attachment points 615, 625.
FIG. 8 is an embodiment of an air mattress 100 comprising a top surface 110, bottom surface 115, a plurality of side surfaces (e.g., side surface 120), and various air mattress 100 components. Further, as shown in FIG. 8, in some embodiments, an air mattress 100 may comprise a portable power source 810. In some embodiments, a portable power source 810 may be a battery and provide direct current. In other embodiments, portable power source 810 may include a motor or generator and provide alternating current. It is contemplated that any portable power source may be used. Further, a portable power source 810 may be housed in a power source housing (not shown) on air mattress 100 for convenient transport. In some embodiments, a portable power source 810 may comprise a power plug 815, which may be attachable to portable power source 810. In some embodiments, however, power plug 815 may be used in lieu of portable power source 810. Power plug 815 may include a variety of power plugs, such as those configured to plug into USB ports and 120V standard outlets. As will be appreciated, while a portable power source 810 may be used in outdoor and indoor locations, a power plug 815 may be suited for indoor use when air mattress 100 is placed near an electrical outlet.
In some embodiments, an air mattress may comprise an air control system 820, which may be used to control air flow and to inflate and deflate an air mattress 100. In some embodiments, a portable power source 810 or a power plug 815 (or a combination of both) may provide power to an air control system 820. In some embodiments, an air control system 820 may include an air intake component 822 and a controller 824. An air intake component 822 may be configured to direct ambient air into the air mattress 100 during mattress inflation and direct air from the air mattress 100 during mattress deflation. In some embodiments, the air intake component 822 may comprise an outer seal that inhibits or allows the flow of outside air into the air control system 820. In some embodiments, the air intake component 822 also may include an inner seal (not shown) that inhibits or allows the flow of internal air between air control system 820 and the air chamber (i.e., interior) of an air mattress 100.
In some embodiments, a controller 824 may be configured to receive user input and control the opening or closing of inner and outer seals and/or inflating and deflating of the air mattress 100 via the air control system 820. In some embodiments, the controller 824 may include one or more processors having memory. Also, in some embodiments, the controller 824 may be configured to execute one or more operating modes. For example, operating modes may include inflation mode, deflation mode, air recirculation mode, and standby mode. In some embodiments, the controller 824 may include one or more electronic components that allow a user to switch between modes.
In some embodiments, inflation mode may begin when the controller 824 receives user input to inflate the air mattress 100. In some embodiments, inflation mode may last until the controller 824 receives additional user input to stop inflating the air mattress 100. In some embodiments, however, the controller 824 may automatically control the speed and duration of inflation based on a predetermined or user supplied air pressure for the air in the air mattress 100. During inflation mode, both the inner and outer seals may be open to allow ambient air to flow into the air mattress 100.
In some embodiments, deflation mode may begin when the controller 824 receives user input to deflate the air mattress 100. For example, in some embodiments, deflation mode may last until the controller 824 receives additional user input to stop deflating the air mattress 100. Further, in some embodiments, the controller 824 may automatically control the speed and duration of deflation based on a predetermined or user supplied air pressure for the air in the air mattress 100. During deflation mode, both the inner and outer seals may be open to allow ambient air to flow out of the air mattress 100.
According to some embodiments, an air recirculation mode may begin when the controller 824 receives user input to circulate air within air mattress 100. In doing so, the controller 824 may direct the outer seal to close while the inner seal remains open, thus allowing air to enter the air intake component 822, but not escape the air mattress 100. According to some embodiments, circulating air within an air mattress 100 may cause a vibrating or massaging pulse on the surface of the air mattress 100 and/or adjust air pressure via air control system 820. In some embodiments, air recirculation mode may last until the controller 824 receives additional user input to stop circulating air within the air mattress 100. Also, in some embodiments, the controller 824 may automatically control the time duration and/or interval to recirculate air within the air mattress 100.
In some embodiments, a standby mode may occur when the controller 824 receives power from portable power source 810 and/or power plug 815 and is not placed in another mode. For example, the controller 824 may operate in standby mode before receiving user input. In some embodiments, the controller 824 may also direct the inner seal to close to inhibit air recirculation. Also, in some embodiments, the controller 824 may direct the inner seal to remain open. It is contemplated that the air mattress 100 may only include the outer seal and not the inner seal, according to some embodiments.
In some embodiments, an air mattress 100 may comprise an air release valve 840. According to some embodiments, an air release valve 840 may be configured to inhibit the flow of air out of the air mattress 100 when the air release valve 840 is in a closed position and allow air flow out of air mattress 100 when the air release valve 840 is in an open position. In some embodiments, an air release valve 840 may move from the closed position to an open position when the air pressure inside an air mattress 100 exceeds a predetermined threshold. In such embodiments, the air release valve 840 may serve as a safety valve to prevent damage to the air mattress 100 from over-inflation. In some embodiments, an air release valve 840 may comprise a removable plug that may be removed when a user desires to deflate the air mattress 100. In some embodiments, an air release valve 840 may be constructed out of polyvinyl chloride ("PVC"). It is contemplated, however, that other materials such as plastics or rubber may be used.
