This novel invention relates to wireless devices (which encompasses cell phones, wireless tablets and/or laptop computers) and particularly to a shielding case, which substantially eliminates the dangers of electromagnetic radiation including but not limited to RF microwave and heat transference emitted from wireless devices. The shielding case also serves as a carrying case for the cellular phone. The invention discloses flat, fixed edging, and flexible edging flip cases for wireless devices, which provide essential shielding for the user.
This invention addresses the concerns over potential health hazards caused by the emission of EMF including but not limited to RF microwave radiation and heat emitted from wireless devices. The invention protects the user from such various types of radiation by using particular shielding technologies such as disclosed in U.S. Pat. Nos. 5,367,309, 6,515,223 and U.S. Pat. No. 7,772,504 to Richard Tashjian as well as pending application Ser. No. 12/883,697. In the present invention, the shielding technology is contained within the storage case for cell phones (aka wireless devices) providing a unique mechanism to protect the wireless devices user.
The present invention focuses on shielding the user from harmful EMF including but not limited to RF microwave radiation and heat, while serving at the same time as a simple, lightweight/compact, protective, attractive, and sturdy case in which the user can carry a wireless device particularly a cell phone. The invention also makes cellular phones more readily and safely available by being able to store the phone on a computer case with a Velcro® accessory strip when placed in a Cellular Shield Case via the accessory Velcro® strip.
Prior art patents of interest in addition to applicant's previously cited U.S. Pat. Nos. 7,772,504; 6,515,223 and 5,367,307 and application Ser. No. 12/883,697 include U.S. Pat. Nos. 7,036,642; 6,349,825; and, 5,124,899. None of the foregoing patents anticipates the unique features of this application. Cases for wireless devices are common but they are generally designed to protect the device not the user.
The present invention shields the laptop (aka wireless device) user from the harmful heat and the EMF generated including but not limited to RF microwave radiation emitted by a wireless device particularly when being used next to user's ear or carried on one's body. The shielding device or case includes a portion, which flips over itself as part of the carrying case and protects the wireless device when stored therein and the user when the phone is operational. The shield technology employed in this invention comprises conductive fabric positioned against a non-conductive plastic then rolled up onto itself on all four sides or can be bonded to each other for easier assembly. This permits a larger functionally effective virtual shielding area while having a physically smaller acting/functioning area. The EMF “sees/reacts” to this shielding area as a larger effective area than it actually is on the cell phone case.
Accordingly, an object of this invention is to provide a new and improved case for carrying wireless devices, which shields the user from harmful radiation.
Another object of this invention is to provide a new and improved flip case for wireless devices, which includes unique shielding elements to protect the user.
Another object of this invention is to provide a new and improved shielding case for wireless devices, which provides four-way protection against radiation whether used against one's head, carried on a belt, carried in a pocket or texting with one's hands.
Another object of this invention is to provide a unique pocket shield for safely carrying wireless devices in one's pocket.
A still further object of this invention is to provide a shielding messenger bag or similar casing for wireless devices having 4-point spacers on one side thereof to provide further protection for one's body.
The above and other objects and advantages of the present invention may be more clearly seen when viewed in conjunction with the accompanying drawings wherein:
a shows a flat flip case for a cellular phone in an open position while
a and
a and
a (case closed) and 6b (case opened) are side views of a wireless device here a laptop PC positioned with a spacer portion for shielding and cooling purposes incorporated in a existing case design;
a depicts an existing messenger bag type case or similar casing design for a cellular phone or wireless tablet including four point riser support on one face thereof to protect the user;
b is a perspective view showing the rear of the messenger bag of 7a or similar type casing and
a and 8b are perspective views of using the flip shielding process incorporated/added to existing open-faced skin cover cases, which have been now converted into insulated shielding cases. All the same, previous benefits stated above apply with the added benefit of further protecting the device especially the screen if impacted in any way.
Referring now to the drawings, this invention relates to primarily to cell phones, but also to wireless tablets and PC notebooks and well as more specifically to a shielding case for such apparatus which substantially eliminates the dangers of EMFs emitting therefrom. The shielding case substantially eliminates RF microwave radiation and heat emitted from these devices by providing enhanced EM insulation as more specifically described by applicant in his prior inventions cited herein.
The wireless device case designs include flat, fixed edging and flexible edging flip cases. All three designs provide four way shielding protection, namely, use against one's head, and use on a belt, pocket carrying, and texting with one's hands. This is accomplished by an EM insulation or shielding barrier in the flap portion of the case.
a and
a and
a and 5b show the wireless device shield pocket 50a and 50b which are placed in different apparel pocket sizes 51a or 51b respectively. The arrangement provides shielding when a wireless device is placed in a pocket for storage or when it is used with a headset. One simply drops the device into a shield pocket opening in a shirt or coat pocket to protect the user's body. The cellular shield pocket 50a or 50b can also be incorporated into existing phone cases.
As shown in
a depicts the shielded messenger bag or similar type case 60 of
a and 8b depict an existing open face skin cover case 80 into which a cell phone 81 is snapped. An insulating strip 82 comprised of a thin durable material is positioned within case 80 against the rear wall 83 before the cell phone 81 is snapped inside it. The strip 82 is attached to the EM shielded flip cover 84 with sides 85a and 85b, which is folded over the phone 81 when in use. The cover 84 is twisted 180 degrees as shown in
While the invention has been explained by a detailed description of certain specific embodiments, it is understood that various modifications and substitutions can be made in any of them within the scope of appended claims, which are intended also to include equivalents of such embodiments.
This application is a Continuation-in-Part of application Ser. No. 12/883,697 filed Sep. 16, 2010 now U.S. Pat. No. 8,205,744.
