Abstract

Abstract A sun deck bubble dome roof attachment formed of transparent plastic and adapted to be easily fitted into a sun deck opening of a rooftop and held in grooves extending about the edges of the sundeck opening by a slide roof retracted and urged against the rear edge of the top attachment to lock the same in the grooves of the sun deck opening. A gasket extends about the edge of the top attachment to provide a watertight engagement of the side edges with the grooves of the sides of the openings. Swingable latch members are provided on the forward and rearward edges of the top attachment serving to clamp the side edges against the bottom walls of the roof top and to prevent its outward release from the sun deck opening. The rubber gasket grips the top in such a manner that should a forced thrust upwardly from within the vehicle as upon the rider being thrown upwardly and with the engagement of his head the roof top will be disengaged so as to prevent the rider from being severely injured by the head blow. The clamp devices provided upon the top attachment are such as to make the engagement with an opening merely cut into the roof of the vehicle to undersize from the area of the bubble top so that the bubble top can be locked in place without the slide door of the sun deck serving to lock the bubble top in place.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 147 words
In combination, vehicle roof-top walls defining as a part thereof a sun deck roof-opening provided therein, at least one oversize bubble dome top attachment shaped in a predetermined shape substantially filling the roof-opening and having an upwardly extending dome-shaped projection and a laterally extending flattened area including forward and rearward edges, said roof-top walls having channel shaped grooves opening inwardly into said roof-opening, the attachment having outer portions of the edges engagable in said grooves within the roofopening, a channel section gasket secured on the outer edge portions overlapping the roof-top walls and accomodated in said grooves within the roof-opening, the roof-top walls having operably mounted within the roof-opening a retractable door cover having a forward edge thereof engageable with the rear edge of the bubble top to press the forward edge of the bubble top into a forward one of said grooves in secure engagement therewith.
Claim 2
Dependent Claim 147 words
In combination, vehicle roof-top walls defining as a part thereof a sun deck roof-opening provided therein, at least one oversize bubble dome top attachment shaped in a predetermined shape substantially filling the roof-opening and having an upwardly extending dome-shaped projection and a laterally extending flattened area including forward and rearward edges, said roof-top walls having channel shaped grooves opening inwardly into said roof-opening, the attachment having outer portions of the edges engagable in said grooves within the roofopening, a channel section gasket secured on the outer edge portions overlapping the roof-top walls and accomodated in said grooves within the roof-opening, the roof-top walls having operably mounted within the roof-opening a retractable door cover having a forward edge thereof engageable with the rear edge of the bubble top to press the forward edge of the bubble top into a forward one of said grooves in secure engagement therewith.
Claim 3
Dependent Claim 86 words
The combination as defined in claim 1 and said gasket being arranged upon the edge of the flattened area portion such as to permit the breakaway of the flattened portion to thereby provide a safety device to permit the separation of the bubble top attachment from the opening upon an upward thrust of the rider and the engagement of his head with the underside of the dome projections and thereby minimize injury to the rider upon the rider being thrown into the roof of the vehicle.
Claim 4
Dependent Claim 61 words
The combination as defined in claim 1, in which the bubble dome top is detachable and the roof-top walls have an underside, and the combination further including clamping means provided on the forward and rear edges of the bubble top, for engagement with the underside of the roof-top walls to hold the bubble dome top attachment within the sun deck opening.
Claim 5
Dependent Claim 83 words
The combination of claim 3, and each of said claimping means comprising a pin extending thRough the flattened portion of the bubble top attachment, and through the gasket flanges, and a clamp arm turnable upon a pin and an eccentric hand clamp member pivoted upon the lower end of the pin and operable against the clamp arm to effect the downward clamping engagement of the edges of the bubble top attachment against the overlapping edges of the walls of the sun deck roof-opening.
Claim 6
Dependent Claim 25 words
The combination as defined in claim 4 and said gasket having inwardly extending lug formations for accommodating the clamp pin member of the clamping devices.
Claim 7
Dependent Claim 69 words
The combination of claim 1, and said bubble top attachment having a further buble projection laterally spaced from the other bubble top projection and positioned to overly another forward seat rider position of a vehicle of which the roof-top walls are a mountable part thereof, and these bubble top projections being each dome shaped and being fromed of transparent material through which view can be made free of glare.
