Abstract

A bed comprising a base having an internal area into which a heat source, in the form of a hot water pipe system is installed, and mineral powder which together with the heat source, fills the internal area of the base and provides a top sleeping surface for the bed. When heated the bed emits far infrared rays which can be absorbed into the human body during sleep. It is thought that a bed of this type would have various therapeutic uses.

Claims

1. A bed for emitting far infrared rays comprising:

a base having an internal space, said internal space lined with a heat lagging material;

mineral powder filling the internal space, the mineral powder providing a top sleeping surface for the bed and comprising 26.67% by weight Al₂ O₃, 0.1% by weight F₂ O₃, 0.22% by weight Na₂ O, 6.87% by weight K₂ O, about 64.67% by weight SiO₂, 0.61% by weight MaO and 0.02% by weight TiO₂ ;

a hot water pipe system fixably mounted within the internal space, substantially below the top surface of the bed, said hot water pipe system being arranged in a serpentine configuration, evenly throughout the mineral powder so that heat is conducted uniformly through the mineral powder and far infrared rays are emitted from the top sleeping surface of the bed;

an external hot water supply connected to said hot water pipe system; and

a fabric cover, at least for the top sleeping surface, having at least one hook and loop fastening means to secure the cover to the base of the bed.

2. The bed according to claim 1 further comprising a means within the internal space of the base of the bed to compartmentalize the mineral powder.

3. The bed according to claim 2 wherein said compartmentalizing means is in the form of at least one bag which contains the mineral powder.

4. The bed according to claim 3 wherein at least one bag is arranged on top of the hot water pipe system.

5. The bed according to claim 1 further comprising a gravel layer located substantially below the hot water pipe system.
