Rotating mirror assembly including a sealed inner chamber

Abstract

A rotating mirror assembly, comprising a mirror including a front surface and a rear surface, a front cover engaged with the front surface, a fluidly sealed cavity formed between the front cover and the mirror, a rim operatively arranged to clamp the mirror and the front cover together, and a wall bracket comprising an aperture, the mirror arranged to rotatably engage the aperture. The cavity is filled with a liquid and snow-flake-like particles.

What is claimed is: 
     
         1 . A rotating mirror assembly, comprising:
 a mirror including a front surface and a rear surface;   a front cover engaged with the front surface;   a fluidly sealed cavity formed between the front cover and the mirror;   a rim operatively arranged to clamp the mirror and the front cover together; and,   a wall bracket comprising an aperture, the mirror arranged to rotatably engage the aperture.   
     
     
         2 . The rotating mirror assembly as recited in  claim 1 , further comprising a seal arranged between the front surface and the cover. 
     
     
         3 . The rotating mirror assembly as recited in  claim 2 , wherein the front cover comprises:
 a meniscus portion edge operatively arranged to engage the front surface;   a concave meniscus portion extending radially inward from the meniscus portion edge; and,   a lip extending radially outward from the concave meniscus portion.   
     
     
         4 . The rotating mirror assembly as recited in  claim 3 , wherein the seal is arranged between the lip and the front surface. 
     
     
         5 . The rotating mirror assembly as recited in  claim 1 , wherein the rim comprises a crimped C-channel rim. 
     
     
         6 . The rotating mirror assembly as recited in  claim 1 , wherein the mirror further comprises a through-bore extending to the cavity, the through-bore operatively arranged to allow the cavity to be filled with liquid. 
     
     
         7 . The rotating mirror assembly as recited in  claim 6 , further comprising a plug operatively arranged to engage the through-bore to fluidly seal the liquid within the cavity. 
     
     
         8 . The rotating mirror assembly as recited in  claim 1 , further comprising liquid arranged in the cavity. 
     
     
         9 . The rotating mirror assembly as recited in  claim 8 , wherein said liquid comprises a glycerin and water solution. 
     
     
         10 . The rotating mirror assembly as recited in  claim 8 , further comprising a plurality of particles arranged in the liquid. 
     
     
         11 . The rotating mirror assembly as recited in  claim 10 , wherein said particles consists of materials selected from the group consisting of bone chips, pieces of porcelain, sand, sawdust, gold foil, non-soluble soap flakes and plastic. 
     
     
         12 . The rotating mirror assembly as recited in  claim 1 , wherein the aperture is key-hole shaped. 
     
     
         13 . The rotating mirror assembly as recited in  claim 1 , further comprising a wheel bracket connected to the rear surface, the wheel bracket comprising a groove operatively arranged to engage the aperture. 
     
     
         14 . A rotating mirror assembly, comprising:
 a mirror including a front surface and a rear surface;   a transparent front cover engaged with the front surface;   a seal arranged between the front surface and the cover;   a fluidly sealed cavity formed between the front cover and the mirror, the cavity being at least partially filled with a liquid;   a rim operatively arranged to clamp the mirror and the front cover together; and,   a wall bracket comprising an aperture, the mirror arranged to rotatably engage the aperture.   
     
     
         15 . The rotating mirror assembly as recited in  claim 14 , wherein the front cover comprises:
 a meniscus portion edge operatively arranged to engage the front surface;   a concave meniscus portion extending radially inward from the meniscus portion edge and axially away from the front surface; and,   a lip extending radially outward from the concave meniscus portion and axially away from the front surface.   
     
     
         16 . The rotating mirror assembly as recited in  claim 15 , wherein the seal is arranged between the lip and the front surface. 
     
     
         17 . The rotating mirror assembly as recited in  claim 14 , wherein the mirror further comprises a through-bore extending to the cavity, the through-bore operatively arranged to allow the cavity to be filled with liquid. 
     
     
         18 . The rotating mirror assembly as recited in  claim 17 , further comprising a plug operatively arranged to engage the through-bore to fluidly seal the liquid within the cavity. 
     
     
         19 . The rotating mirror assembly as recited in  claim 14 , further comprising a plurality of particles arranged in the liquid. 
     
     
         20 . The rotating mirror assembly as recited in  claim 1 , wherein:
 the aperture is key-hole shaped;   the mirror is connected to a wheel bracket including a groove; and,   the groove is operatively arranged to removably engage the aperture.
