DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a heating bed, which is especially intended for therapeutic purposes.
1. Field of the Invention
It is known that the use of heat can considerably relieve the pain caused by rheumatic pains, wear and tear of the skeleton, especially of the spine, and the pains resulting therefrom, and similar bodily ailments. For the most part, the heat treatment in such cases is carried out outside the home of the person afflicted in special institutions, such as hospitals or the treatment rooms of doctors. The drawback to this is that on the one hand such a treatment can only very unsatisfactorily follow the individual requirements of an adapted treatment program; furthermore, the success of the treatment can be more or less called in question due to the fact that after the treatment the afflicted person must on his way home, for example in an unheated vehicle, be exposed to unfavorable climatic conditions for a more or less long period of time, especially with regard to low outside temperatures.
2. Description of the Prior Art
The invention therefore proceeds from the idea that the success of heat treatment can on the average be considerably improved if the treatment is carried out in the home of the afflicted person. Accordingly, it is an object of the present invention to provide an apparatus which, with regard to the aforementioned field of bodily illnesses, makes it possible in particular to carry out heat treatment in the home of the afflicted person. Such an apparatus can, of course, also be used in clinics and similar treatment centers.
SUMMARY OF THE INVENTION
To resolve this object, the present invention proposes a heating bed or bed-like heating apparatus which is characterized by a box-like container which is opened toward the top for receiving fine-grained, heat-storing material, especially sand, and is furthermore characterized by a heating device, for the aforementioned material, located in the container and essentially extending over the entire container, and finally by a textile cover which closes off the top of the container, rests upon the aforementioned material, and is secured to the container. The sand which is utilized is preferably quartz sand or ocean sand.
The inventive apparatus enables an intensive yet very uniform heat treatment of a person resting thereupon, with the sand, preferably quartz sand, causing the heat to be uniformly supplied to all body zones which face the sand. The textile cover, which is preferably placed upon the sand with a certain amount of slack, prevents direct contact of the person resting thereon with this heat-storing and heat-transmitting material. In addition to physiological and hygenic reasons, this textile cover therefore also serves to keep the pertaining room clean.
The heating device is, of course, embodied in such a way that the temperature of the sand, which stores heat and gives it off uniformly to the person resting thereon, can be adjusted, i.e. the temperature can be expediently regulated.
In order to avoid unnecessary loss of heat, it is proposed pursuant to one inventive embodiment to provide a layer of predetermined thickness between the bottom of the container and the aforementioned material, with the layer comprising an insulating material, such as granular, foamed polystyrene.
Furthermore, also with regard to keeping heat loss as low as possible, it is expedient if pursuant to another inventive embodiment there is provided between the bottom and the aforementioned material (e.g. sand) a layer is provided which reflects thermal radiation, for example an aluminum foil possibly coated with a film of plastic.
The heating device can have various forms; various energy carriers can also be used, such as hot air which is circulated through a coil of pipe which is guided in a meander fashion in the sand bed. In a preferred embodiment of the invention, it is proposed that the heating device be embodied as an electrical surface heating element, and that an electrical grounding grid be disposed in
