US 4,671,284 A · Sauna support bed

Abstract

A personal sauna has a horizontally extending bed for supporting an individual in a recumbent position, and combines the benefits of heat and vibration by means of a transversely recirculating air system and a motive means which simultaneously moves the bed with both relatively fast vibrations and relatively slow, longitudinally oscillating rocking motions. The air recirculation system comprises a chamber extending longitudinally beneath the bed supporting the individual, and two elongated heating elements disposed below opposite side regions of the bed heat air which is then directed upwardly to a compartment surrounding the body at substantially equal airflow rates along the entire length of the bed. Transverse airflow through the compartment minimizes the face velocity of the flowing air, and thereby reduces the likelihood of drafts while substantially eliminating the occurrence of localized relatively hot regions within the compartment. A headrest, stationary relative to the osciallating bed, supports the head exteriorly of the compartment and introduction of fresh air into a region surrounded by U-shaped walls provides an air curtain for minimizing the escape of heated air from the compartment, while supplying a sufficient quantity of fresh, cool air for breathing purposes.

Dependent claims

In a sauna having walls defining a compartment and an elongated, horizontally extending bed connected to said walls and positioned at least partially within said compartment for supporting an individual in a recumbent position, said bed having longitudinally extending, opposed, side regions, means for uniformly directing heated, recirculating air to all portions of an individual's body lying atop said bed, said means comprising:

structure defining an elongated chamber beneath said bed and extending substantially along the entire length thereof;
blower means coupled to said structure for introducing recirculated air to said chamber;
heating element means having a longitudinal axis parallel with the longitudinal axis of the chamber and extending substantially the entire length of said chamber;
elongated air inlet means extending substantially the entire length of said heating element means and said chamber for distributing air from said blower means evenly to all regions along the length of said heating element means in longitudinally transverse relationship to the latter;
and
elongated air outlet means extending substantially along the entire length of said bed and communicating said heating element means with said compartment for distributing air from said chamber and heated by said elements to an individual's body lying atop said bed with a generally uniform airflow rate along the length of the body and without excessive air face velocities.

a pair of elongated air inlets each extending substantially along the length of a respective one of said heating elements in longitudinally transverse relationship to the latter;
and
a pair of elongated air outlets parallel to said air inlets and oppositely disposed adjacent said side regions of said bed,
each of said air outlets being associated with one of said heating elements and being in communication with said compartment,
each of said air outlets extending substantially along the length of said bed for distributing air from said chamber and heated by said elements to an individual's body lying atop said bed with a generally uniform airflow rate along the length of the body and without excessive air face velocities.
