Sleeping device comprising an active heat absorbing/releasing layer in combination with a spacer material layer

Abstract

The present invention relates to a sleeping device, such as a mattress, quilt or pillow, wherein the sleeping device is adapted to be used by a person during rest and comprises a core element, wherein said core element is covered by a first layer of a material having temperature regulating properties by absorbing and releasing heat and a second layer of down. By using a material with temperature regulating properties together with a layer of down filling, very good properties of minimizing temperature variations are obtained.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of and claims the benefit of priority to U.S. application Ser. No. 11 / 294,898, filed Dec. 6, 2005. The contents of the aforementioned application is incorporated herein by reference in its entirety for any purpose whatsoever.FIELD OF THE INVENTION[0002]The present invention relates to a sleeping device, such as a mattress, pillow or quilt.BACKGROUND OF THE INVENTION[0003]During sleep the human body goes through different phases, and in these phases the body temperature varies both as a result of internal temperature changes in the body during sleep and because of variations of the temperature in the surroundings. These temperature variations disturb the sleep. It is especially important in connection with the sleep that the most important phase—the REM phase—is undisturbed, because in this phase the brain is recharged and prepared for the next waken period. Another effect of the temperature changes is th...

AI Technical Summary

Benefits of technology

The patent describes a sleeping device that uses a material with temperature regulating properties and a layer of spacer material to minimize temperature variations. This helps to improve the performance of the temperature regulating material, and also helps to prevent the user from getting sick, improving their immune system. The device also reduces the risk of the mattress getting sweaty, which means it doesn't need to be cleaned as frequently. The spacer material used is distance mess, which can adjust the hardness and spring characteristics, and a third layer of down filling can further improve the function of the temperature regulating material. Overall, this patent provides a technical solution for creating a comfortable and healthy sleeping experience.

Problems solved by technology

These temperature variations disturb the sleep.

Another effect of the temperature changes is that the quilt covering the person is kicked off during sleep, which often results in the person waking up later by freezing.

Further, the temperature changes might also result in a sweaty, wet mattress.

In both cases the temperature change does not only disturb the sleep, but might also result in sickness.

A problem with this solution is that during sleep moist from the body is generated, and the moist is then absorbed in the layer following the phase change material which typically could be the core of a mattress or a layer of synthetic filling between the core and the phase change material.

The moist decreases the effect of the phase change material considerably, whereby the introduction of the phase change material does not sufficiently solve the problem of minimizing the temperature variations during sleep.
