Sliding roof device for automobiles

Claim 2

A sliding roof device for a vehicle having a roof with an opening being disposed therein comprising: a sliding roof operatively positioned to close the opening in the roof of the vehicle, said sliding roof including a front surface, a rear surface, an upper face and a lower face; a roof frame; frame side guide rails mounted on said roof frame and having a first end and a second end, said first end being positioned at a lower elevation relative to the roof opening than said second end; front slide stays secured to the front surface and lower face of the sliding roof; front moving members attached to said front slide stays and operatively positioned to be movable back and forth along said frame side guide rails; sub guide rails mounted on said roof frame; rear slide stays secured to the rear surface and lower face of the sliding roof; rear moving members attached to said rear slide stays and operatively positioned to be movable back and forth along said sub guide rails; wherein upwardly tilting the rear surface of said sliding roof and displacing said sliding roof to a roof back position with said front moving members being guided and elevated along said frame side guide rails from said first end towards said second end varies the angle of inclination of said sliding roof relative to said opening in the roof of the vehicle while displacing the rear surface of the sliding roof downwardly; and an elastic member operatively positioned between said sliding roof and said roof frame and being adapted to be compressed by said sliding roof when said roof is fully opened to push and bias said sliding roof upwardly.

Claim 3

A sliding roof device according to claim 1, wherein said elastic member is disposed on said front moving members and below said front slide stays.

Claim 4

A sliding roof device according to claim 1, and further including a link member operatively connected to each of said front moving members, said elastic member being affixed to said link member to push and bias said sliding roof upwardly when in the fully opened position.

Claim 5

A sliding roof device according to claim 1, and further including a tilt-up mechanism operatively connected to said sub guide rails for changing the elevation of said sub guide rails relative to opening in the roof of the vehicle.

Claim 6

A sliding roof device for a vehicle having a roof with an opening being disposed therein comprising: a sliding roof operatively positioned to close the opening in the roof of the vehicle, said sliding roof including a front surface, a rear surface, an upper face and a lower face; a roof frame; tilt-up means for tilting the rear surface of said sliding roof; frame side guide rails including main guide rails and sub guide rails mounted on said roof frame; said main guide rails having a first end and a second end, said first end being positioned at a lower elevation relative to said second end in relation to the roof opening, said sub guide rails being adapted to be rearwardly tilted upward, front and rear slide stays mounted on the lower face and both sides of said sliding roof; said front slide stays being guided along said main guide rails; said rear slide stays being guided along said sub guide rails and being inclined at an angle to be rearwardly elevated when the sliding roof is in the tilted position in such a manner that the rearward displacement of the sliding roof causes the inclination angle of the rear slide stays to decrease; moving members attached to said front and rear slide stays and operatively positioned to be movable back and forth along said frame side guide rails wherein upwardly tilting the rear surface of said sliding roof and displacing said sliding roof to a roof back position with said moving members being guided and elevated along said frame side guide rails varies the angle of inclination of said sliding roof relative to said opening in the roof of the vehicle while displacing the rear surface of the sliding roof downwardly; and an elastic member operatively positioned between said sliding roof and said roof frame and being adapted to be compressed by said sliding roof when said roof is fully opened to push and bias said slding roof upwardly.

Claim 7

A sliding roof device for a vehicle having a roof with an opening being disposed therein comprising: a sliding roof operatively positioned to close the opening in the roof of the vehicle, said sliding roof including a front surface, a rear surface, an upper face and a lower face; a roof frame; tilt-up means for tilting the rear surface of said sliding roof; frame side guide rails including main guide rails and sub guide rails mounted on said roof frame; said main guide rails having a first end and a second end, said first end being positioned at a lower elevation relative to said second end in relation to the roof opening, said sub guide rails being adapted to be rearwardly tilted upward, front and rear slide stays mounted on the lower face and both sides of said sliding roof; said front slide stays being guided along said main guide rails; said rear slide stays being guided along said sub guide rails and being inclined at an angle to be rearwardly elevated when the sliding roof is in the tilted position in such a manner that the rearward displacement of the sliding roof causes the inclination angle of the rear slide stays to decrease; moving members attached to said front and rear slide stays and operatively positioned to be movable back and forth along said frame side guide rails wherein upwardly tilting the rear surface of said sliding roof and displacing said sliding roof to a roof back position with said moving members being guided and elevated along said frame side guide rails varies the angle of inclination of said sliding roof relative to said opening in the roof of the vehicle while displacing the rear surface of the sliding roof downwardly; and an elastic member operatively positioned between said sliding roof and said roof frame and being adapted to be compressed by said sliding roof when said roof is fully opened to push and bias said slding roof upwardly.

Claim 8

A sliding roof device for a vehicle according to claim 5, wherein said sub guide rail is arcuately formed to curve upwardly.
