Abstract

A display device .Iadd.comprises a base panel .Iaddend.having a plurality of .[.base.]. .Iadd.unit .Iaddend.panels. Each .[.base.]. .Iadd.unit .Iaddend.panel has an arm projecting perpendicular to the plane of the base panel. The arm has a .[.flat portion parallel to the plane of the base panel at an upper end of the arm, and slat area at a lower end of the arm. A pin is disposed at the end of the arm to suspend freely a reflecting plate, which moves about by breeze to provide an attractive shimmering effect..]. .Iadd.terminal top end surface, a width of which is greater than the height thereof in front view. A rod, having a head, extends from the terminal top end surface of the projecting arm, to which a reflector plate is loosely and swingably fitted.Iaddend..

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A display device comprising a base panel having a plurality of .[.plastic.]. unit panels, each of said unit panels having a .[.plastic.]. projecting arm formed integrally with said unit panel at the center of said unit panel and near the top of said unit panel, a .[.rivet.]. .Iadd.rod .Iaddend., having a .[.rivet.]. head, .[.embedded in.]. .Iadd.extending from .Iaddend.the terminal top end surface of said projecting arm, and a reflector plate loosely and swingably fitted to said .[.rivet.]. .Iadd.rod.Iaddend., wherein said terminal top end surface of said projecting arm and said .[.rivet.]. .Iadd.rod .Iaddend.comprise means for restricting the swinging movement of said reflector plate about said .[.rivet.]. .Iadd.rod .Iaddend.in a direction toward and away from said .[.unit.]. panel as the back surface of said reflector plate contacts one end of said terminal top end surface of said projecting arm and the front surface of said reflector plate contacts .[.one end of said rivet.]. .Iadd.said rod .Iaddend.during swung positions of said reflector plate, said terminal top end surface of said projecting arm .[.has.]. .Iadd.having .Iaddend.a width greater than the height thereof in front view .[.and comprises a vertical upper surface section and an inclined lower surface section, said upper surface section being parallel to said unit panel while said lower surface section being inclined toward said unit panel as it extends downwardly from the upper surface section, the degree of inclination of said lower surface section and the height of said rivet being such that when said reflector plate positioned in a normal suspended position is swung backward about said rivet, the upper front surface of said reflector plate contacts the upper end of the head of said rivet, and the lower end of said reflector plate is still slightly spaced from said unit panel.].. .[. 
     
     
       2.  A display device as claimed in claim 1, wherein said inclined lower surface section of said terminal top end surface of said projecting arm forms an angle in the approximate range of 19-28 degrees relative to the vertical plane and the height of said rivet is such that when said reflector plate is inclined with the upper end portion thereof contacting the upper end of the head of said rivet, said reflector plate is inclined along said inclined lower surface section..]. 
     
     
       3. A display device as claimed in claim 1, wherein said base panel comprises a number of grooves formed in a lattice form longitudinally and transversely on the surface thereof, whereby said base panel can be separated along said grooves to provide a panel of desired shape. 
     
     
       4. A display device as claimed in claim 1, wherein said reflector plate has a longitudinal slot extending in a direction toward the center thereof from the peripheral portion thereof through which reflector plate is loosely fitted to said .[.rivet.]. .Iadd.rod.Iaddend., said slot having a lateral width smaller than the diameter of the head of said .[.rivet.]. .Iadd.rod .Iaddend.and a longitudinal width larger than the diameter of the .[.rivet.]. .Iadd.rod .Iaddend.head. 
     
     
       5. A display device as claimed in claim 1, wherein said reflector plate consists of a reflecting film layer of aluminum, a semitransparent pigment-colored layer formed on one surface of said reflecting film layer, a transparent plastic layer formed on the surface of said colored layer, and a protective layer of plastics coated on the other surface of said aluminum film layer. 
     
     
       6. A display device as claimed in claim 1, wherein said unit panel has a hole approximately at its center through which said unit panel is secured by means of a fixing member. 
     
     
       7. A display device as claimed in claim 1, wherein said unit panel is square and said reflector plate is circular. 
     
     
       8. A display device as claimed in claim 1, wherein said projecting arm has a substantially pentagonal configuration in cross section with opposite parallel upper side surfaces, tapered lower side surfaces extending from the lower ends of said upper side surfaces and an upper surface extending between the upper ends of said side surface. .Iadd. 9. A display device as claimed in claim 1, wherein said terminal top end surface of said projecting arm further comprises a vertical upper surface section and an inclined lower surface section, said upper surface section being parallel to said unit panel while said lower surface section being inclined toward said unit panel as it extends downwardly from said upper surface section. .Iaddend..Iadd. 10. A display device as claimed in claim 9, wherein the degree of inclination of said lower surface section and the height of said rod are such that when said reflector plate positioned in a normal suspended position is swung backward about said rod, the upper front surface of said reflector plate contacts the upper end of the head of said rod, and the lower end of said reflector plate is still slightly spaced from said unit panel. .Iaddend..Iadd. 11. A display device as claimed in claim 10, wherein said inclined lower surface section of said terminal top end surface of said projecting arm forms an angle in the approximate range of 19-28 degrees relative to the vertical plane and the height of said rod is such that when said reflector plate is inclined with the upper end portion thereof contacting the upper end of the head of said rod, said reflector plate is inclined along said inclined lower surface section. .Iaddend. .Iadd. 12. A display device as claimed in claim 1, wherein said rod is a rivet embedded in the terminal top end surface of said projecting arm. .Iaddend..Iadd. 13. A display device as claimed in claim 1, wherein said unit panel and said projecting arm are integrally formed by plastic. .Iaddend. .Iadd. 14. A display device comprising a base panel having a plurality of unit panels, each of said unit panels having a projecting arm formed integrally with said unit panel at the center of said unit panel and near the top of said unit panel, a rod, having a head, extending from the terminal top end surface of said projecting arm, and a reflector plate loosely and swingably fitted to said rod, said terminal top end surface of said projecting arm and said rod being so dimensioned that when said reflector plate positioned in a normal suspended position is swung backward about said rod, the upper front surface of said reflector plate contacts the upper end of the head of said rod, and the lower end of said reflector plate is still slightly spaced from said unit panel. .Iaddend.
