Abstract

A mobile telephone screen is covered with a lens, fixed on one end and set free on the other or fixed on both ends. When the fonts don'"'"'t need to be magnified, the Fresnel lens tightly sticks to the mobile telephone screen; and when need, the free end of the Fresnel lens will be unfolded or both ends of it will be carried as a whole to magnify the fonts. Without increase in the thickness of mobile phone, the fonts on screen can be magnified conveniently and a magnification scale can be freely adjusted according to the magnitude of the unfold or the carry. A bridge piece in the device has the an adjustable and telescopic structure that can be adjusted according to the width of the mobile phone. A suction cup is elastic one that can adhere to the both sides of mobile phone.

Claims

1. A device for magnifying images on a mobile phone screen, comprising:

a telescopic bridge piece extending laterally across an upper face of the mobile phone;

left and right brackets projecting orthogonally from each end of the bridge piece and extending, respectively, along portions of left and right facing sides of a body of the mobile phone;

left and right fixing members for respectively attaching distal ends of the left and right brackets to the left and right facing sides of the body of the mobile phone;

a Fresnel lens having one end directly connected to the bridge piece in a manner such that the Fresnel lens is pivotable about an axis of the bridge piece;

wherein the Fresnel lens is pivotable about the bridge piece between a position lying flat against and covering the screen of the mobile phone, in which case the images on the screen are not magnified, to one or more positions in which a plane of the Fresnel lens is oriented at an acute angle with respect to the screen, in which case the images on the screen are magnified when viewed by a user viewing the screen through the Fresnel lens.

2. The device magnifying images on a mobile phone screen according to claim 1, wherein the left and right fixing members are suction cups for respectively attaching the distal ends of left and right brackets to the left and right facing sides of the mobile phone body.

3. The device magnifying images on a mobile phone screen according to claim 2, wherein the suction cups are elastic suction cups.

4. The device magnifying images on a mobile phone screen according to claim 1, wherein the body of the mobile phone comprises two fixing apertures formed, respectively on the left and right facing sides of body of the mobile phone for fixing the distal ends of the left and right brackets onto the body of the mobile phone.

5. The device magnifying images on a mobile phone screen according to claim 1, wherein the bridge piece is freely telescopic in order to position and attach the left and right brackets along the left and right facing sides of mobile phones with bodies of different widths.

6. A method of magnifying images on a mobile phone screen, the mobile phone having a telescopic bridge piece extending laterally across an upper face of the mobile phone;

left and right brackets projecting orthogonally from each end of the bridge piece and extending, respectively, along portions of left and right facing sides of a body of the mobile phone;

left and right fixing members for respectively attaching distal ends of the left and right brackets to the left and right facing sides of the body of the mobile phone; and

a Fresnel lens having one end directly connected to the bridge piece in a manner such that the Fresnel lens is pivotable about an axis of the bridge piece, the method comprising;

pivoting the Fresnel lens about the bridge piece to a position flat against and covering the screen of the mobile phone, in which case the images on the screen are not magnified; and

pivoting the Fresnel lens about the bridge piece to one or more positions in which a plane of the Fresnel lens is oriented at an acute angle with respect to the screen, in which case the images on the screen are magnified when viewed by a user viewing the screen through the Fresnel lens.
