Description

Radiant heat footrest.

Object of the invention

The present invention aims to patent a heat radiator object designed to heat the feet of the person who uses it since it is a footrest heater, and secondarily, radiate heat to the room where it is located and the surrounding objects, being able to be considered a team for the heating.

Specifically this utility model proposes to use an electric resistance, of resistive wire of nickel-cadmium, nickel-chromium or other electro-conductive material, which extended to length and width of the base that serves as support, is covered by another panel, and the sandwich thus formed will become part of its instead of the footrest structure. This way the footrest, it  converts into a heat radiator, heating the environment that surrounds you through radiation instead of convection, being the healthiest radiation principle by not heating appreciably the surrounding air but the objects, and more ecological at represent a greater use of energy, with a contribution additional consisting in the total elimination of the risk of accidental burns based on the same heating principle by radiation, therefore, the low temperature at which it works is perfectly bearable by most materials of use everyday, this being especially beneficial for the body human, on which it has a direct application when working warming the feet of the person using it.

Field of the Invention

This invention has its application within the manufacture of heating objects and furniture in general.

Description of the invention

The heating principle we are referring to is known in the current state of the art and it is about take advantage of the heat emitted by the electrical resistance of the wire of nickel, chrome or any other resistive material electro-conductor In this invention, the thread resistive extends forming a circuit, in such a way that it covers widely the surface that serves as a base. The circuit formed by the resistive wire continues through some wires conductors, appropriate to the electrical power of the element, which connect in turn to a source of electrical energy, making possible dissipation of electrical power of the wire in the form of hot. In this way we manage to distribute the heat output on a surface, achieving superior performance and more healthy when acting this source of radiation heating, warming the feet of people who use the footrest as well like the objects around, but minimally the air of the room that contains it and therefore avoiding the effect of convection on which most of the heating systems, this also makes it more ecological to Represent a greater use of energy. However, the main advantage offered by the heating object is the salutary of this system to warm the feet of people who use it by the low temperature at which it works, distinguishing itself in this one point of any other system invented to heat that part of the body while the person is sitting in front of a desk or table, and this is its main feature and novelty, since the conventional heating equipment used to heat the human body directly, such as braziers, heaters Ground air, infrared bulbs etc., make their use too close to the body or too long bring consequences harmful for health, mainly for the device circulatory, given the high temperature that reaches the skin more close to the source of heat emission, especially when used too close. The designed object can not only cause injury by burn or analogous some, but it provides the necessary heat to make the sensation of cold feet disappear that despite being in perfectly acclimated rooms accompanies the People during the winter months.

Apart from the design, size, or material, the Footrest that we propose will consist of some elements basic as they are; A double panel containing the wire circuit conductor, without the composition of this material influencing a relevant way in the final result of the heating footrest object of the present invention, being constituted by materials commonly used in the manufacture of furniture in general, such as the different types of wooden boards, polyurethane or other synthetic or natural materials, characterized by having high thermal and electrical insulation power; Also a thread of conductive resistance of electricity, having the characteristic of warming up the moment it connects to a electric power source The conductive wire is placed on the panel that serves as a base, tracing any shape whenever cover the objective of distributing evenly in it, having chosen for the preferred embodiment a line drawing in zig Zag; This circuit is carried to two electric conduction cables (one for each pole) that will meet in a common plug that It will connect to the mains, or other source of electrical energy. All of the above is covered by another panel that protects and insulates it from outside, using for this some insulating bands located between the circuit fixed in the base panel and the cover panel. He sandwich thus formed is integrated into the footrest structure with Adjustable legs to give the desired inclination to the footrest (Although the footrest can also be manufactured with a fixed inclination given).

The final aesthetics of the heating object obtained It can be as varied as designs want to make this object piece of furniture.

Description of the drawings

To complete the description that is being performing and in order to help better compression of peculiarities of the heat radiator integrable panel that We propose, this document is attached as part  member of it the drawings arranged in the pages following in which, explanatory and not limiting In any case, the following has been represented:

Figure 1.- Shows the base panel and the circuit electric on which the electric circuit expands.

Figure 2.- Shows the section of the footrest.

Figure 3.- Shows all the elements footrest members.

Description of the preferred embodiment

The detailed description of the embodiment preferred of the process of the present invention and of the elements that compose it, it is done in view of the figures described. Figure 1 shows the base panel (2), formed by a insulating material such as wood or some of its derivatives, over which a compound closed electrical circuit is coupled to its instead of a two-wire (3) resistive cable Nickel-Cadmium or other alloy arranged along and  width of one of the bases making comings and goings so that cover its surface widely. The inclusion in the circuit of a safety thermostat or regulator of temperature (7), in any case optional and not relevant in the novelty that is presented as patentable, but as possible constituent element of this preferred embodiment.

Figure 2 shows how the electrical circuit (3), formed by the resistive wire, is trapped between the base panel (2), of wood or its derivatives, and the panel that covers it (4), which for this preferred embodiment has a panel Tempered glass, heat resistant and easy to clean, plus durable, and all this, fits in the recess made for such effect on the structure of the footrest (1).

Figure 3 shows the integration of elements that form the electrical circuit in the footrest (1). Be observe, then, how the glass panel is in contact with some insulating bands (5) and not directly on the electrical circuit and how the ends of the electricity conductor wire (3), are they join in a bipolar cable that ends in a common plug or power strip connection (6) to be connected to the mains, or other energy source thus forming an electrical circuit.

So, we get through the radiator footrest heat heat, by radiation instead of convention, the feet to lean on it in an ecological way, for being using a electrical power much lower than that needed by other means heating. We also get the heat emitted by the footrest does not constitute a fire hazard to objects that surround it or damage to health, and that the materials used for the composition of the object in this embodiment preferred are common, as is wood, and not especially characterized to build a heating device, being all at the low temperature at which the activity takes place heater of the element object of the present invention.

Made the description referred to in the report above, we point out that the footrest shown in the drawings as an example, it is not limiting in terms of shape, size or complexity Indeed, in the current Patent Law, set as non-patentable, changes in shape, dimensions, proportions and materials of an already patented object, thus setting the criteria of the legislator in the sense that an idea is patented, no one can rely on it, on the pretext of having introduced slight modifications, present it as new and own. Exists also enough innovation to understand that a piece is provided new, as is a footrest heater made with materials Common non-specialized, easy to use and handle, more ecological, Safe and natural that convection heating means.

We understand therefore that the improvement with elements such as a "safety thermostat" that interrupts the power supply to prevent the object from overheating under certain circumstances, or even a "thermostat temperature regulator ", are not elements that come to create of this one invented a new and different one with enough novelty inventiveness. Likewise, we show that the inclusion in the electrical circuit described here of a transformer that makes work on it at a voltage lower than that of the power grid common, it is not constitutive of inventive novelty enough to Precede to this invention.

It is not considered necessary to make the content of this description for a subject matter expert can understand its scope and the advantages derived from the invention, as well as develop and implement the object of the same.
