Benefits of technology

"The patent text describes a sleeping device that solves the problem of temperature variations during sleep. The device comprises a layer of material with temperature regulating properties and down filling. The temperature regulating material helps to minimize temperature variations and improve the quality of sleep. The device also reduces the risk of getting sick, improves the immune system, and reduces the need for cleaning. The temperature regulating material can be a phase change material, and the device can be designed based on the user's needs. The down filling can be goose down, which is good at absorbing moist. The sleeping device can be a pillow, mattress, or quilt, and can be designed to minimize temperature variations around the body or head of the user."

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 of during sleep, which often results in the person waking up later on freezing.
Further, the temperature changes might also result in sweaty, wet sleeping devices.
In both cases the temperature change does not only disturb the sleep, but might also result in sickness.

Embodiment Construction

[0018] New materials have been developed in an attempt to address special clothing and other thermal regulating system requirements. For example, microencapsulated phase change materials have been described as a suitable component for substrate coatings when exceptional heat transfer and storage capabilities are desired.

[0019] In U.S. Pat. No. 5,290,904 substrates are described, which are coated with a binder containing microcapsules filled with energy absorbing phase change material. These microcapsules enable the substrate to exhibit extended or enhanced heat retention or storage properties.

[0020] Also by way of example, microencapsulated phase change materials have been described as a suitable component for inclusion in fibres, when exceptional heat transfer and storage capabilities are desired. In U.S. Pat. No. 4,756,958 a fibre with integral micro spheres filled with phase change material or plastic crystals has enhanced thermal properties at predetermined temperatures. This ...

Abstract

The present invention relates to a sleeping device, such as a pillow, mattress or quilt, wherein the sleeping device is adapted to be used by a person during rest and comprises a first layer of a material having temperature regulating properties and a second layer of down filling. 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

FIELD OF THE INVENTION [0001] The present invention relates to a sleeping device, such as a pillow, mattress or quilt. BACKGROUND OF THE INVENTION [0002] 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 for 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 that the quilt covering the person is kicked of during sleep, which often results in the person waking up later on freezing. Further, the temperature changes might also result in sweaty, wet sleeping devices. In both cases the temperature change does not only disturb the sleep, but might also result in sickness. OBJ...
