Sheath for cellular mobile telephone with a screening of electromagnetic emission into the sheath

Abstract: The invention consists of a screening (1) in nylon enriched with nickel and carbon yarns to be integrated with the inside face (2) of the sheath, where the surface of the screening (1) and the surface of the inside face (2) are in contact and come to contain and to protect the cellular telephone. Said screening (1) to be provided also for covering the opening (3) of the sheath to have access to the push-button telephone so to screen each part of the cellular telephone.

Description: The invention refers to a new embodiment into the sheathes for the cellular mobile telephones consists of a screening of the outside face to be integrated inside the housing part of the sheathes. Said screening, which comes to be the essential feature of the invention, sensibly reduces the emission outside of the electromagnetic radiations. Being provided for completely wrapping the cellular telephone, with the same one inside the sheath, the screening covers also the opening for the push-button telephone so better protecting the human body from the radiations. In the current use of the cellular mobile telephones is unsolved the big problem to protect the user from the radioactive and electromagnetic waves which do harm both inside and outside organs of the body. It must to be considered that the symptoms to be found out for the presence of an energy, that one of emission of the cellular telephone, which comes to attack a second one, that of the human body, are easily to be seen in some immediate more showy aspects like dimming or loss of the sight, cerebral tiredness, loss of sensibility of the sence-organs, giddnesses and nauseas. The continuity of said esposition can moreover origin, with the organologic decay, also the growth of tumours. The current sheathes, to be used only to protect the cellular telephones from the accidental crashes and from the atmospheric agents and to permit the right grip of these very delicate electronic devices with miniaturized parts, are not able to offer an ordinary protection against said radiations. To better understand the difficulties which have had who has tried for resolving the problem, it is to be noted that the sheath, anyhow made, must not have covering part of big thickness. This because the big dimension causes problem for gripping the telephone and moreover hampers to easily transport it on the body, for example onto the belt, or into bags or handbags. The problem regarding the dimensions persists using the current cushion screenings forming sheathes with high encumbrance and consequently with the current means is impossible to solve the radiation problem. Consequently, up to now, on the base of precise and unbreakable market demands it has being necessary to renounce to a screening for said radiations. At present the sheathes for cellular telephones on the market are of two kinds: the first one of elastic film with insignificant thickness, to determine a protection sheath which comes to be in contact with the closed body of the contained cellular telephone, and a second one consists of leather or imitation of leather cases with inner coating where the thickness is that of the same leather. The invented screening permits to opportunely screen the inside part of the sheath and, having said screening an insignificant thickness, does not create the problem of big dimensions. Using said screening is so possible to protect user from the injurious radiations emitted by the cellular telephone without neglecting the necessity of smallest thickness and flessibility that a sheath must have. The invented screening permits a medium demolishing value of 40% of the injurious radiations emitted by the cellular telephone, however, said value may change on the base of the used frequences and of the components used. The invention consists of a screening 1 in nylon enriched with nickel and carbon yarns to be integrated with the inside face 2 of the sheath, where the surface of the screening 1 and the surface of the inside face 2 are in contact and come to contain and to protect the cellular telephone. Said screening 1 to be provided also for covering the opening 3 of the sheath to have access to the push-button telephone so to screen each part of the cellular telephone. In a preferred embodiment is provided a bi-faced material with the inside face consists of the screening 1 and with the outside face consists of the external wrapping structurat ed to contain the telephone. Using said bi-faced material the sheathes are realized with lower working time. The forming phase foresees at first the realization by punching of the screening 1 and of the sheath with its inside face 2. Said screening 1 is then integrated in composition on the inside face 2 of the sheath by means of sewing. In a preferred embodiment, realized as example, a parallelepipedal sheath is provided to be realized by coupling of the screening 1 in nylon enriched with nikel and carbon yarns and of a leather material with inside face 2. The opening by means of which the cellular telephone is introduced into the sheath housing is then to be closed by two self-sticking parts 4. Considering the high resistance to the traction permits by the material forming the screening 1, which acts like structuring of the sheath, it is permitted the coupling of said screened material with a second material of minimum thickness and big flessibility. A version of the invented screened sheath is illustrated in schematic views in the drawings of sheets 1 and 2. In sheet 1 fig. 1 apart view of the screening 1 in a possible parallelepipedal shape. Fig. 2 is view of the starting form realized by punching of the screening 1. In sheet 2 fig. 3 is view of a sheath with integrated the screening 1 in opening with in its inside a cellular mobile telephone. Fig.4 is perspective view in closing of the same sheath of fig. 3 with in its inside the cellular telephone.

Claims: Sheath for cellular mobile telephone with a screening of the electromagnetic emission into the sheath, wherein the screening (1) in nylon enriched with nickel and carbon yarns is to be integrated with the inside face (2) of the sheath, where the surface of the screening (1) and the surface of the inside face (2) are in contact and come to contain and to protect the cellular telephone; and where said screening (1) is to be provided also for covering the opening (3) of the sheath to have access to the push-button telephone so to screen each part of the cellular telephone. Sheath for cellular mobile telephone with a screening of the electromagnetic emission into the sheath, as defined in claim 1, characterized in that a bi-faced material is provided with the inside face consists of the screening (1) and with the outside face consists of the external wrapping structurated to contain the telephone, so using said bi-faced material the sheathes are realized with lower working time.
