Abstract
An air mattress having one or more inflatable, air-tight chambers where the firmness is adjustable using a pumping system controlled by one or more remote control units. As an improvement over the prior art, the pumping system is installed within the confines of the mattress and outside of the inflatable chambers to increase overall efficiency, accuracy, reliability, and environment compatibility of the mattress while maintaining the ease of diagnostics and repair. This new art also makes the mattress more user friendly by reducing perceivable pumping noise and by relieving the hassle of dealing with hoses and external pump of the prior art. The air mattress may also include any and all features of the prior art such as mattress edge support foam and layers of comfort-providing foam.
Description
- A conventional air mattress consists of four basic components: mattress cover, support and cushioning foam, one or more air-tight chambers with hoses, and one or more pumping systems.
- The mattress cover is a fabric that encloses most of the other mattress components. In the prior art, these components only include the air chambers, and support and cushioning foam. The mattress cover is usually opened and closed by a combination of zippers and Velcro to allow for easy access to parts and to make washing easier.
- The cushioning foam is typically one or more layers of any combination of super-soft foam, memory foam, and convoluted foam (also known as egg crate foam). Theses layers of foam are placed toward the top of the mattress inside the mattress cover to provide a softer and more supportive sleep surface for the user.
- The support foam usually consists of high density foam rails at the four edges of the mattress inside the mattress cover. These foam rails provide more support at the edges of the mattress to prevent the user from accidentally rolling out of bed. The support foam also gives the mattress a more consistent rectangular shape and increases the usable area of the sleep surface.
- The air tight chambers are typically made of polyvinyl PVC, polyurethane or rubber with or without fabric lining. The air chambers are individually adjustable using one or more pumping systems. The pumping systems are connected to each air chamber by air hoses made of rubber, PVC, or plastic. Each air chamber is made firmer by pumping air into the chamber. Each air chamber is also made softer by letting air out or by pumping air out. These actions are all performed by the pumping systems.
- The pumping systems typically have a hose connector for each air chamber, a remote control for each intended user, and a power port. For example, for a mattress intended for a husband and wife with two air chambers, the pumping systems would have two remote controls, two hose connectors, and a power port. The remote controls are made easily accessible to users lying on the bed and are typically stored on nightstands or in custom pockets in the sides of the mattress. The remotes controls usually have a pressure display to indicate the firmness of the user's air chamber, a button to increase the desired firmness, and a button to decrease the desired firmness. Some models also have a button to completely fill the air chamber and a memory button to store the user's preference and to set the air chamber to the preferred firmness.
- In the prior art, the pumping systems are stored outside the mattress cover. The suggested solution was to have the user install the pumping systems under the bed frame or behind a dresser. This creates a substantial amount of hassle for the users. It also allows the pumping systems and air hoses to be vulnerable to dust, leakages, blockages, and other physical hazards. It also decreases the pressure control accuracy and efficiency. The pumping systems may also be louder depending on where they are installed.
- The inflatable air mattress with imbedded pump invention includes all of the basic components and positive aspects of the prior art of air mattresses. It also eliminates the problems with all pumping systems of the prior art without any detrimental effects. By engineering the pumping system to be installed inside the mattress cover and support foam structure, the following advantages are gained and objectives are realized.
- The pumping systems become better protected from dust, blockages, and other physical hazards by the mattress cover and foam structure.
- The overall mattress reliability is increased as air hoses connecting the air chambers to the pumping systems are less susceptible to kinking and leakages because they are shorter and not exposed to external elements.
- The air chamber firmness control accuracy and efficiency of the pumping systems are increased because the pumping systems are connected to each air chamber by shorter air hoses.
- The perceivable noise of the pumping systems is greatly reduced by the natural muffling properties of the surrounding mattress cover and foam.
- The mattress maintains a cleaner, less obtrusive appearance, is easier to install, and is safer to use because there are no more air hoses sticking out of the mattress and the pumping systems are hidden completely out of sight.
- The mattress is more compatible with platform beds, adjustable beds, and RV beds because there are no external hoses and pumps to deal with.
- These advantages are realized by designing the pumping systems to fit within the boundaries of the mattress cover. This is typically at the foot of the mattress either imbedded in the support foam or between air chambers. However, the concept of this invention still applies to any design where one or more pumping systems are located within the air mattress.

FIG. 4 is a top planar view of the prior art with the top half of the mattress cover removed. -
FIG. 5 is a side sectional view of the inflatable air mattress with imbedded pump. - Reference will now be made in detail to the preferred embodiment of the present invention, examples of which are illustrated in the accompanying drawings.
- In
FIG. 1 , there is a perspective view of thepresent invention 1 as a standalone unit. It will typically be placed on top of a bed foundation or a box spring with a bed frame. However, it may also be placed directly on the floor for use. The external parts include atop mattress cover 2 and abottom mattress cover 3 that are attached at the four edges of the mattress bymattress cover zippers 5. These three components enclose all other parts of the mattress, excepting theremote controls 45, to provide a clean and crisp appearance and to protect internal components from dust and other environmental factors. This zippered design allows for the mattress covers to be easily removed for cleaning or replacement. It also makes installation of internal components easy. - The remote controls 45 as shown in
FIG. 1 are readily accessible to each user to set the desired firmness of each side of the mattress. Same as in the prior art of air mattresses, each remote has a display that shows the firmness setting, an increase firmness button, a decrease firmness button, a fill button to set the mattress to maximum firmness, and a memory button to set and recall the particular user's mattress firmness preference. There is typically oneremote control 45 for each simultaneous user to control his or her side of the mattress. For example, inFIG. 1 there are two remote controls installed for two simultaneous users to control two halves of the mattress. If there is only one user, the mattress may come with one remote to control the mattress as a whole. -
FIG. 2 reveals the layers ofcomfort foam 21 located within thetop mattress cover 2. As in the prior art, these layers provide a soft, supportive, and consistent sleep surface for the users. These layers are usually made of memory foam, convoluted foam, latex foam or a combination of them. Thecomfort foam 21 is usually preferred, but in some variations of the present invention, they may be removed. Some reasons to do this are to reduce the cost of the mattress, to meet weight restrictions, or the particular user dislikes foam. -
FIG. 3 depicts the current invention from a top planar view with the top mattress cover removed. Same as the prior art, there are four strips of edge support foam around the sides of the mattress: The head endedge support foam 32, two strips of sideedge support foam 33, and the foot endedge support foam 34. These strips of high-density foam stabilize the air chambers, provide the firm sitting edge and prevent the user from accidentally rolling out of bed, effectively increasing the usable surface of the mattress. They also help the mattress maintain its shape and clean appearance. In some variations of the present invention, up lo three of the edge support foam strips may be removed. Some reasons to do this are to reduce the cost of the mattress, to meet space or weight restrictions, or the particular user dislikes foam. - Also as in the prior art, there are two
inflatable chambers 31 that are tilled with air to a certain internal pressure that determines the mattress firmness. Eachinflatable chamber 31 is individually adjustable by using thepumping system 41 to pump air in, and to pump or let air out. In some variations of the present invention, there may be only one inflatable chamber. This is because some users prefer to control the entire mattress as one unit rather than the two sides separately. There may also be more inflatable chambers according to user preferences. In these cases, thepumping system 41 is equipped with an equivalent number ofair delivery ports 43 connected to the number of desired inflatable chambers throughair hoses 42. - There are many disadvantages to the air mattresses of the prior art. As shown in
FIG. 4 depicting an air mattress of the prior art, thepumping system 81 is located outside of themattress 80. This requireslong air hoses 82 to extend from inside the mattress to the external pumping system. This leaves theair hoses 82 of the prior art exposed and more susceptible to damage, kinks, and leaks. The airtight seal 84 between theinflatable chamber 71 and theair hose 82 is also vulnerable to damage and leaking due to physical forces exerted on the air hose from outside the mattress. For example, if a user trips on an exposedair hose 82, the force exerted may pull the hose and compromise the air-tight seal 84. Air transfer efficiency and pressure measurement accuracy are low due to the high air friction against the inside walls of the long hoses. Thepumping system 81 is also vulnerable to environmental hazards such as dust and physical strikes from surrounding objects. The users are also readily susceptible to noise from the pumping system. The pumping system is also obtrusive and more difficult to install as the user has to find a place to store it. This is further complicated when the user is installing the mattress on a platform foundation and cannot store the pumping system under a bed frame. These problems and complications are all solved by the present invention. -
FIG. 2 andFIG. 3 depict the present invention. Thepumping system 41 transfers air to and from eachinflatable chamber 31 through anair hose 42 connected to each chamber to effectively control the firmness of the mattress. As in the prior art of air mattresses, eachinflatable chamber 31 is individually adjustable. When the user activates aremote control 45 to change the mattress firmness of the corresponding side of the mattress, thepumping system 41 measures the internal pressure of the correspondinginflatable chamber 31 using a pressure transducer. If the internal pressure of theinflatable chamber 31 is lower than the desired setting, thepumping system 41 inflates theinflatable chamber 31 by pumping air in until the desired pressure setting is reached. If the internal pressure of theinflatable chamber 31 is higher than the desired setting, thepumping system 41 deflates theinflatable chamber 31 by letting or pumping air out until the desired pressure setting is reached. Thepumping system 41 also protects theinflatable chambers 31 from over-inflation by stopping the pumps when maximum pressure is achieved. - As shown in
FIG. 2 andFIG. 3 , thepumping system 41 is located within the support foam at the foot end of the mattress. Because thepumping system 41 is imbedded in the foot endedge support foam 34, the noise created by the pumping system is muffled and dampened by the foam andmattress cover support foam 34 andmattress cover - Each inflatable chamber has an
air hose 42 that connects to thepumping system 41 through an air-tight screw-onconnector 43. Eachair hose 42 is internally reinforced with steel coils to prevent the tube from kinking and is permanently shaped at a 60° to 120° angle to allow for easy air delivery without stressing the airtight seal 44 between theinflatable chamber 31 and theair hose 42. This design increases the reliability and durability of theair hoses 42. The air hoses are shaped at an angle by bending them and then using shrink tubing to permanently hold the tubing in the bent position. The shrink tubing must be sufficiently strong to hold the air hoses permanently. The air hoses may also be shaped permanently by heated treatment methods. Theair hoses 42 are permanently fixed to theinflatable chambers 31 by an airtight seal 44. In some variations of the present invention, the inflatable chamber may instead have a screw on connector to which the air hose is attached. In case of leaks or damage, it is possible to replace the inflatable chamber or air hose without replacing the other. - As shown in
FIG. 3 , theair hoses 42 are also imbedded in the foot endedge support foam 34 and are therefore more reliable and less susceptible to leaking and damage because they are not exposed to as many external forces. The airtight seal 44 between theair hose 42 and theinflatable chamber 31 is also better protected from damage. Theair hoses 42 are shorter than those of the prior art, thus decreasing the amount of air friction within them. This allows for more efficient transfer of air to and from theinflatable chambers 31, which also leads to more accurate measurement and control of the internal pressure of eachinflatable chamber 31. The degree to how much of theedge support foam 34 surrounds theair hoses 42 varies. In some cases, the air hose may only rest on the foam surface while in other cases it may be encased in foam. - The present invention effectively hides the
pumping system 41 andair hoses 42 from sight, making it more aesthetically pleasing. This makes the air mattress safer to users by eliminating tripping hazards. It also makes it easier to install and more compatible with bedding solutions such as platform foundations by eliminating the need to organize the air hoses and find a place to store the pump. - The inflatable air mattress with imbedded pump set forth above the present invention provides an adjustable sleep system that yields improved comfort, reliability, accuracy, efficiency, structural compatibility, safety, ease of installation, and reduced noise levels over the prior art. The inflatable air mattress with imbedded pump may be used in all bedrooms including homes, hotels, motels, and RVs on a continual basis.
- While the present invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
