Description

Thermal heating unit.

The present invention relates to a unit thermal heating, preferably usable as blanket in rescues, sports expeditions or similar events even though discard other uses (for example, as a thermal element forming part of warm clothes, sleeping bags or the like).

In the current state of the art they are known materials, elements or thermal garments with structuring diverse that start from a common concept which is to incorporate internally heating elements that are recharged by plugging in a source of energy.

From this basic conception, they are known inventions referring to electric structuring blankets diverse; for example and among others:

-

In a old technology, the utility model UO215554, referred to a electric blanket structured in two stitched layers that delimit among them spaces in which elements carrying bearers are housed electric resistance; that connect to a current network, for its operability

-

In a recent technology, patent EP1654910, referring to a blanket electrical comprising an operating unit and a unit of power supply that can be connected to that and to the power grid for recharge

Even thermal blankets with means are known to allow, interchangeably, to heat or cool the user (for example patent ES2293852, with preferred application in physiotherapy) or other objects, whether electric blankets (for example patent EP0946952), outerwear (for example the patent ES2049670 and utility model U0198876) or simply  heating fabrics (for example, the ES2179786 patent).

The thermal unit object of the invention presents regarding everything known a new structuring that makes Very light, flexible versatile and easy to use. It is characterized because It consists of a first cover, exterior and that defines the dimensions of the piece of coat, structured in layered layers closable to each other and open to dispose inside a second case, compartmentalized and configured as a module removable, in each of whose compartments at least a non-conductive carrier carrying at least one resistor electric

From this basic conception, they are indistinct, and are included in the object of the invention, any practical realizations that do not alter, change or modify the proposed essentiality, as well as any configurations that adopt the finished coat pieces (blankets, vests, jackets, pants, sleeping bags or any others).

To better understand the purpose of this invention, a preferred form of practical realization, susceptible to accessory changes that do not distort its foundation.

Figure 1 shows a partial scheme of a heating thermal unit according to the invention, deployed (in plan) and partially sectioned to observe its structure general and arrangement of components.

Figure 2 shows a partial section elevation schematic of a heating unit thermal agreement with the invention, according to indication A: A of the previous figure.

Figure 3 shows a non-limiting scheme of  DC electric circuit (5) with a plurality of resistors (4) connected in parallel. It is indistinct and accessory to  the effects of the invention the amount of resistors (4), which will be function of the dimensions of the thermal unit to be constituted in each case.

Figure 4 shows, in general scheme, a example of carrying a transport bag (8), with its components-handles (80) and with a compartment external (81) power supply carrier (6).

An example of practical, non-limiting embodiment of the present invention. I dont know discarded at all other embodiments in which introduce accessory changes that do not distort its foundation; by On the contrary, the present invention also covers all its variants.

The object of the invention is a thermal unit heater that can be used as a thermal element as part of, for for example, blankets, clothing, sleeping bags or, in general, pieces of coat.

In accordance with the invention, and according to the Embodied representation -See figures 1 and 2-, the aforementioned unit Thermal heating basically consists of:

-

a first outer case (1)

-

a second inner case (2)

-

to the less, a non-conductive support (3)

-

to the less, an electrical resistance (4)

-

a power supply (6)

-

a regulating thermostat (9)

In the heating thermal unit object of the invention said first outer cover (1) defines the dimensions of the piece of coat and is structured in layered layers a of base (11) and another one of covers (12), closable to each other with means (13), for example, zippers. Particularly, these layers base (11) and cover (12) laminar are made of materials different: the base (11) is, for example, strong material and Non-slip and cover (12) is, for example, very material lightweight and flexible

When opening the zippers (13) the layers (11), (12) are separated and allow to arrange inside the mentioned second case (2).

In accordance with the invention and according to the embodiment depicted, said second inner sheath (2) is compartmentalized and configured as a removable module. In one, several or all compartments (21) of the inner sheath (2) are have one or several non-conductive supports (3) carriers each one of at least one electrical resistor (4).

The aforementioned electrical resistors (4) go interconnected with each other as part of a current circuit continued (5) which, in turn, provides means for connect / disconnect to said power supply (6).

Particularly, the aforementioned resistances electrical (4) are connected in parallel in the circuit of direct current (5). -See figure 3-

The DC circuit (5) has a  regulation thermostat (9) to control the temperature of the coat piece -See figure 3-

The aforementioned power supply (6) is portable and, in turn, is recharged in a power grid conventional.

In accordance with the invention, and according to the Embodied embodiment, said thermal heating unit additionally it consists of means (7) for its folded retention. These means (7) are, for example, self-adhesive strips -type velcro®- arranged in several areas of the base layer (11), or in extended perimeter tabs (11 ') of it, and that overlap each other in the closure to keep folding.

For transport to destination, the folded piece (configured, for example, as a blanket) folded and retained in its folded position thanks to the aforementioned means (7) so that it is easily disposed in a carrying bag (8).

Preferably, in said bag of transport (8), which has its own elements such as handles or braces (80) to facilitate their work, the cited power supply (6) for which carrying bag (8) has a separate compartment (81). -See figure 4-

The materials may be variable, dimensions, proportions and, in general, those other details accessories or secondary that do not alter, change or modify the proposed essentiality.

The terms in which this report is written they are true and faithful reflection of the object described, being taken in its broadest sense and never in a limiting way.
