Generally, the present disclosure relates to bedding, and, more specifically, to a mattress system comprising a mattress and one or more electrical or electronic devices configured to operate based on an inductive electrical power supply.
Foam mattresses, such as viscoelastic or “memory foam” mattresses, provide desirably high levels of firmness and support for many users. However, one common consumer complaint regarding foam mattresses is that they “sleep hot,” i.e., that the mattress tends to retain the user's body heat and render the mattress less comfortable for sleep.
In an effort to alleviate the tendency of foam mattresses to “sleep hot,” workers have created airflow channels within a mattress. For example, U.S. Pat. No. 6,866,915 discloses a mattress including a viscoelastic foam layer atop a middle layer, wherein the middle layer has a non-plane surface abutting the viscoelastic foam layer. The non-plane surface may contain undulations, thereby providing airflow channels between the undulations.
However, the presence of an airflow channel in a mattress may be insufficient of itself to provide sufficient airflow to alleviate the problem of “sleeping hot.”
The present disclosure may address and/or at least reduce one or more of the problems identified above.
The following presents a simplified summary of the disclosure in order to provide a basic understanding of some aspects of the disclosure. This summary is not an exhaustive overview of the disclosure. It is not intended to identify key or critical elements of the disclosure or to delineate the scope of the disclosure. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is discussed later.
In one embodiment, the present disclosure is directed to a mattress, comprising at least a first support layer comprising at least a first channel extending from a first side of the mattress to a second side of the mattress, wherein the first channel has a first opening at the first side of the mattress and a second opening at the second side of the mattress; and at least a first air movement device disposed at the first opening or the second opening of the first channel.
In one embodiment, the present disclosure is directed to a mattress assembly, comprising at least a first support layer comprising at least a first channel extending from a first side of the mattress to a second side of the mattress, wherein the first channel has a first opening at the first side of the mattress and a second opening at the second side of the mattress; and at least a first fan disposed at the first opening or the second opening of the first channel; and a mattress foundation disposed under the mattress.
In one embodiment, the present disclosure is directed to a mattress, comprising at least a first support layer comprising a non-viscoelastic foam and at least a first channel and a second channel, wherein each channel extends from a first side of the mattress to a second side of the mattress, and each channel has a first opening at the first side of the mattress and a second opening at the second side of the mattress; at least a first fan and a second fan, wherein the first fan is disposed at the first opening or the second opening of the first channel, and the second fan is disposed at the first opening of the second channel, the second opening of the second channel, or the first opening or the second opening of the first channel at which the first fan is not disposed; at least one support member disposed within at least the first channel, wherein the at least one support member is configured to permit a flow of air therethrough or therearound; and a comfort layer disposed above the first support layer, wherein the comfort layer comprises a viscoelastic foam.
The present disclosure may provide for mattresses with a reduced tendency to “sleep hot.”
The disclosure may be understood by reference to the following description taken in conjunction with the accompanying drawings, in which like reference numerals identify like elements, and in which:
While the subject matter disclosed herein is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail.

Embodiments herein are directed to mattresses comprising at least one device capable for moving air, e.g., a fan, disposed at an opening of a channel through a support layer of the mattress or an electrostatic air movement device. The air movement device may provide cooling to a user of the mattress by impelling air into or withdrawing air from the channel.
Further, embodiments herein provide for zoned control of airflow. For example, certain channels in a mattress may be selected in order to provide airflow, wherein other channels may be left idle with respect to airflow. Moreover, airflow in channels of a mattress may be controlled in such a manner that the temperature of the mattress may be influenced by controlling the airflow. For example, airflow in certain channels in the mattress may be controlled such that regions proximate to those channels may experience increased cooling or heating. In this manner, zoned temperature control may be provided using airflow control provided by embodiments herein.
Further, embodiments herein provide for user control of airflow in a mattress. For example, a user may control the operations of the air moving devices via a remote device, such as mobile phone, a tablet, a remote control device, a laptop computer, or any electronic device that is capable of communicating with a control device for controlling the operations of the air moving devices in the mattress. In some embodiments, an application (app) may be used by a user of a mobile device to control the operations of air moving devices.
Turning to
The mattress 100 includes a first layer 120. The first layer 120 comprises at least one channel 122, e.g., as shown in
For ease of illustration, embodiments herein are described in terms of the air movement device being a fan. However, those skilled in the art having benefit of the present disclosure, would appreciate that other type of an air movement devices may be implemented in embodiments herein. For example, the air movement device 126 may be electrostatic air mover. For example, the drawings represented by the fans 126a and 126b may be electrostatic air moving devices. In one embodiment, the electrostatic air moving device 126 may comprise two oppositely charged electrodes, wherein a first electrode may generate ions by electrical means, e.g., a corona discharge. The ions may then be attracted to a second electrode, which has an opposite charge as the first electrode, which may cause movement of air. Accordingly, the fans 126 described herein may be a device having blades to move air, or alternatively, may use electrical means, (e.g., electrostatic air movement) to move air.
In some embodiments, wherein the air moving device 126 is an electrostatic air moving device, a corona discharge may be utilized to cause an air movement. For example, discharge of corona may be used for implementing an air velocity electrostatic pump, i.e., a corona pump.
In an electrostatic air device, ions interacting with an electric field may cause an acceleration of the ions. This flow of ions provides causes an airflow within an air flow region, such as a duct or channel system within a mattress. The airflow may be controlled by the geometry of the electric field as well as the intensity of the electric field. In some embodiments, the electric field may run parallel to the walls of a channel or duct through which the airflow is guided.
In some embodiments the airflow, whether generated using an electrostatic air moving device 126 or one or more fans (126a, 126b), may be controlled by a remove wireless device, such as a mobile phone device, a tablet device, a laptop computer, etc. For example, an application installed on a mobile phone may be capable of communicating with the air moving device, and controlling one or more functions.
In some embodiment, the air moving device may comprise one or more small fans, e.g., micro fans. In many embodiments, each fan 126 may have any case size, blade size, speed, or other parameters known in the art. In one embodiment, all fans 126 in a single mattress 100 may be identical in size, speed, and other parameters. In embodiments, it may be desirable for the fans 126 to have relative large case and blade sizes and relatively slow speeds, in order to provide a given amount of airflow with relatively low noise, given that the noise of a fan is generally correlated with the fan's speed.
Each fan 126 may receive electrical power from one or more sources. In one embodiment, each fan 126 may be powered by direct current (DC), e.g. by one or more batteries. In one embodiment, each fan 126 may be powered by alternating current (AC), such as through cabling electrically connected to a transformer connected to a main electrical line.
In one embodiment, each fan 126 is configured for inductive charging. Inductive charging may provide greater convenience than that provided by alkaline, nickel-cadmium, or other batteries, which require frequent replacement, and may also provide greater convenience and esthetic quality than that provided by electrical cables, which require routing and positioning into and/or along the mattress 100.
More generally, in embodiments wherein a mattress system comprises any electrical or electronic device or devices, one, some, or all of the electrical or electronic device(s) may be configured to operate based on an inductive electrical power supply. Examples of electrical or electronic devices that may be configured to operate based on an inductive electrical power supply include, but are not limited to, cooling devices other than air movement devices (e.g., water cooling devices and thermoelectric cooling devices), heating devices (e.g., heating coils and electric blankets), pressure adjustment devices (e.g., air bladders for increasing or decreasing firmness), massage devices, sensors for detecting one or more environmental conditions (e.g., temperature or humidity) or user events (e.g., motion of the user's body; input made through a user interface to change an operation of a device), motors, including pneumatic and hydraulic systems, for adjusting one or more positions of the mattress 100 or other elements of the mattress system, and control units configured to control operation of one or more other devices, among others. Sensors and control units will be described in more detail with reference to
Generally, inductive electrical power supplies require a base station 105 to generate an electromagnetic field and a receiving unit (e.g., an induction coil) in the electrical or electronic device configured to operate based on an inductive electrical power supply. The receiving unit converts energy from the electromagnetic field into electrical energy in the device. By “configured to operate based on an inductive electrical power supply” is meant both battery-mediated operation (i.e., the receiving unit outputs electrical energy that is stored in a battery or batteries, and the electrical or electronic device draws operating power from the battery or batteries) and direct operation (i.e., the receiving unit outputs electrical energy that is used by the electrical or electronic device for operating power without battery storage).
Any arrangement of base station 105 and an electrical or electronic device (e.g. fan 126) may be used in embodiments herein. In one embodiment, the electrical or electronic device may comprise a battery or batteries and be configured for rapid placement and removal from its operating position in the mattress system. In this embodiment, the electrical or electronic device may be temporarily removed from the mattress system, placed in close proximity to a base station 105 for inductive charging of the battery or batteries, and replaced in its operating position in the mattress system. In a particular example of this embodiment, the base station 105 and the electrical or electronic device may conform to a wireless power standard, such as the Qi wireless power transfer standard.
In another embodiment, the base station 105 may be placed near the mattress system, e.g. on a nightstand or other piece of bedroom furniture, and the electrical or electronic device may remain in its operating position in the mattress system.
The first layer 120 may comprise a visco-elastic foam, a non-viscoelastic foam, or a polyurethane foam, among other materials. In one embodiment, the first layer 120 comprises a non-viscoelastic foam. The first layer 120 may be referred to herein as a “support layer.”
In the depicted embodiment, the mattress 100 may also comprise a comfort layer 130 disposed directly above the first layer 120. The comfort layer 130 may comprise any material and/or assemblage of sublayers suitable for providing comfort to a user reclining on the mattress 100. In one embodiment, the comfort layer 130 comprises a foam. In a particular embodiment, the comfort layer 130 comprises a viscoelastic foam. For example, the viscoelastic foam may have a density from about 25 kg/m3 to about 250 kg/m3, such as from about 50 kg/m3 to about 120 kg/m3. In an even more particular embodiment, the viscoelastic foam may have a density of about 80-85 kg/m3. Alternatively or in addition, the viscoelastic foam may have a hardness from about 5 N to about 20 N, such as a hardness of about 10 N. Alternatively or in addition, the comfort layer 130 may include a base sublayer and a pillow-top sublayer.
The first layer 120 and the comfort layer 130 may be bonded together by any suitable adhesive. The first layer 120 and the comfort layer 130 (if any) may be assembled using any process and/or equipment known in the art.
For the avoidance of doubt, and in accordance with practice before the United States Patent and Trademark Office, none of the present figures are to scale.
