structure of display frame

Abstract

An improved structure of a picture display frame comprising a framework, a picture and a grating plate, wherein the picture has more than one image, and is assembled with the grating plate in the framework. The grating plate has a smooth plane surface facing outwards of the framework and has an undulated surface formed from a series of columns facing inwards of the framework and are opposite to the picture spaced therefrom, a gap is formed between the picture and the grating plate; the gap is set to be equal to depth of focusing of the columns of the grating plate formed in refraction of light beams. The surface of the grating plate can be applied by spraying with scraping durable paint, it needs not to increase the thickness of the grating plate for having a deep focus and a good stereographic effect, this largely reduces the cost of the grating plate.

1 . An improved structure of a picture display frame comprising:
 a framework with an opened side;   a grating plate having a smooth plane surface and an undulated surface formed from a series of columns which are arciform in sections, and being provided at said opened side; and   a picture having more than one image mounted in said framework and being parallel to said grating plate;   said grating plate is mounted in said framework with said smooth plane surface of said grating plate facing outside of said framework and with said undulated surface formed from said columns (which are arciform in sections) facing inwards; a gap formed between said picture and said grating plate is set to be equal to depth of focusing of said columns of said grating plate formed in refraction of light beams.   
   
   
       2 . The improved structure of a picture display frame as claimed in  claim 1 , wherein said smooth plane surface of said grating plate is applied by spraying with transparent scraping durable paint. 
   
   
       3 . The improved structure of a picture display frame as claimed in  claim 1 , wherein said smooth plane surface of said grating plate is covered with a protective transparent plastic plate or glass plate. 
   
   
       4 . The improved structure of a picture display frame as claimed in  claim 1 , wherein an inner side of a bottom surface of said framework is installed with a light emitting member, and said framework is provided therein with electronic elements such as a power line for providing said light emitting member with electric power, a voltage stabilizer and a switch. 
   
   
       5 . The improved structure of a picture display frame as claimed in  claim 1 , wherein a picture is stuck onto a plane plate, said framework is provided with a device for adjusting angular position and height of said plane plate, in order that said picture is adjusted relatively to said grating plate for getting its correct display position. 
   
   
       6 . The improved structure of a picture display frame as claimed in  claim 5 , wherein said device for adjusting angular position and height of said plane plate has a movable slide plate at an inner upper area of said framework, said movable plate is fixedly provided thereon with a bolt and a nut, said nut is locked by another bolt slipped in it from outside of a bottom of said framework, said framework has a fixed bolt at a lower area inside of it, four corners of said framework are provided each with a round stub to support and fix said grating plate; near said four round stubs inside of said framework, there are four further nuts on said framework, said four nuts each is locked by a bolt extending from outside of said bottom of said framework for supporting and adjusting height of said plane plate, said plane plate for being stuck thereon said picture is provided on its upper area with a rectangular notch and is provided on its lower area with a round hole, said rectangular notch is slipped over said bolt of said movable plate, and another nut is used to slip over said bolt of said movable plate, said round hole provided on a lower area of said plane plate is slipped over said fixed bolt on a lower area of said framework, and another nut is used to screw connect with said fixed bolt; said grating plate is mounted over said picture ( 104 ) and is fixed by said framework. 
   
   
       7 . The improved structure of a picture display frame as claimed in  claim 1 , wherein said grating plate is a cylindrical mirror grating. 
   
   
       8 . The improved structure of a picture display frame as claimed in  claim 1 , wherein said grating plate is a narrow seam grating. 
   
   
       9 . An improved structure of a picture display frame comprising:
 a display having a surface for displaying a picture;   a grating plate having a smooth plane surface and an undulated surface formed from a series of columns which are arciform in sections, and being provided on said surface of said display; and   said picture, having more than one image and being parallel to said grating plate;   said smooth plane surface of said grating plate faces outwards of said surface of said display, and said undulated surface formed from a series of columns faces inwards of said display; a gap is formed between said grating plate and said picture, said gap is set by depth of focusing of said series of columns of said grating plate formed in refraction of light beams.   
   
   
       10 . The improved structure of a picture display frame as claimed in  claim 9 , wherein said grating plate is provided at its peripheral sides with a plurality of bracing members, said bracing members each is screw connected with a movable bolt on said display; said movable bolts are rotated to adjust verticality of said grating plate and to adjust a gap between said grating plate and said picture on said display; so that said picture is adapted to adjusting relatively to said grating plate for getting its correct display position.
