Abstract

A transparent roof structure in a vehicle which includes a roof glass (100) which includes a reinforced net layer and a net glass layer (110) which is formed of a first glass layer (114) and a second glass layer (116) formed in an upper and lower surface of the reinforced net layer (112), respectively, a pillar glass (200) which is formed of the net glass layer (110) and is extended from a front end corner of the roof glass (100) in a slanted downward direction, a wind shield (300) which is formed of a transparent glass and is extended from a front end of the roof glass (100) and an inner end of the pillar glass (200), a supporter (500) which includes a holder portion (510) having a glass engaging groove (512) to which a lower portion of the windshield (300) is engaged and an engaging portion (520) which is extended from the holder portion (510).

Claims

1. In a vehicle, a transparent roof structure, comprising:

a roof glass which includes a reinforced net layer and a net glass layer which is formed of a first glass layer and a second glass layer formed in an upper and lower surface of the reinforced net layer, respectively;

a pillar glass which is formed of the net glass layer and is extended from a front end corner of the roof glass in a slanted downward direction;

a wind shield which is formed of a transparent glass and is extended from a front end of the roof glass and an inner end of the pillar glass;

a supporter which includes a holder portion having a glass engaging groove to which a lower portion of the wind shield is engaged, an engaging portion which is extended from the holder portion, and a plurality of supporter engaging holes formed in a width direction of the engaging portion; and

a ring frame which is installed in each side of the roof glass, the pillar glass, the wind shield and the rear window, respectively.

2. The structure of claim 1, wherein said first glass layer, second glass layer and wind shield are formed of one selected from the group comprising a poly glass, reinforced plastic, and tempered glass.

3. The structure of claim 1, wherein an air layer and a third glass layer are formed on an upper surface of the first glass layer of the roof glass.

4. The structure of claim 3, wherein a photosensitive glass layer is formed on an upper surface of the third glass layer, and an infrared ray reflection glass layer is formed on an upper surface of the photosensitive glass layer.

5. The structure of claim 1, wherein a liquid crystal glass layer which is changed into a transparent state or a non-transparent state based on whether a power is supplied or not is formed on a lower surface of the second glass layer.
