US4148477A — Simulated ski slope slide structure

Claim 1

Independent Claim 268 words

A simulated ski slope slide structure comprising: an elongate forwardly and downwardly inclined deck with top and bottom surfaces, front and rear ends and opposed sides; an elongate endless carrier belt with inner and outer surfaces and including a longitudinally extending upper portion above the deck with its inner surface in sliding supported engagement therewith, a longitudinally extending lower portion freely below the deck and front and rear recurvant end portions extending between related ends of said upper and lower portions and about the front and rear ends of the deck; primary roller means adjacent the front and rear ends of the deck and engaging the carrier belt; means rotatably driving the roller means whereby the carrier belt is moved about the deck with said upper portion thereof moving rearwardly and upwardly across the deck; a bed of flaked ice on and carried by the carrier belt at the outer surface thereof and presenting a substantially upwardly disposed skiing surface at the upper portion of the belt; an elongate endless retaining belt with inside and outside surfaces and including a top portion extending longitudinally below the lower portion of the carrier belt with its outer surface in supporting and driving engagement with the bed of ice on the lower portion of the carrier belt, whereby said bed of ice is held engaged on the carrier belt, a bottom portion extending longitudinally below said top portion and front and rear turned end portions between and joining the top and bottom portions; and second roller means supporting the carrier belt for free movement of that belt with the carrier belt.

Claim 2

Dependent Claim 268 words

A simulated ski slope slide structure comprising: an elongate forwardly and downwardly inclined deck with top and bottom surfaces, front and rear ends and opposed sides; an elongate endless carrier belt with inner and outer surfaces and including a longitudinally extending upper portion above the deck with its inner surface in sliding supported engagement therewith, a longitudinally extending lower portion freely below the deck and front and rear recurvant end portions extending between related ends of said upper and lower portions and about the front and rear ends of the deck; primary roller means adjacent the front and rear ends of the deck and engaging the carrier belt; means rotatably driving the roller means whereby the carrier belt is moved about the deck with said upper portion thereof moving rearwardly and upwardly across the deck; a bed of flaked ice on and carried by the carrier belt at the outer surface thereof and presenting a substantially upwardly disposed skiing surface at the upper portion of the belt; an elongate endless retaining belt with inside and outside surfaces and including a top portion extending longitudinally below the lower portion of the carrier belt with its outer surface in supporting and driving engagement with the bed of ice on the lower portion of the carrier belt, whereby said bed of ice is held engaged on the carrier belt, a bottom portion extending longitudinally below said top portion and front and rear turned end portions between and joining the top and bottom portions; and second roller means supporting the carrier belt for free movement of that belt with the carrier belt.

Claim 3

Dependent Claim 61 words

The slide structure set forth in claim 1 wherein said carrier belt is established of carpet material having a flat back defining its inner surface and a fibrous pile defining its outer surface, with said bed of ice at the outer surface of the carrier belt being inter-engaged with the pile, whereby the bed and carrier belt are mechanically locked together.

Claim 4

Dependent Claim 40 words

The slide structure set forth in claim 2 wherein the outside surface of the retaining belt is textured and impresses a corresponding texture in the surface of the bed of ice when it is engaged with said bed of ice.

Claim 5

Dependent Claim 40 words

The slide structure set forth in claim 1 wherein the outside surface of the retaining belt is textured and impresses a corresponding texture in the surface of the bed of ice when it is engaged with said bed of ice.

Claim 6

Dependent Claim 121 words

The structure set forth in claim 1 wherein said primary roller means includes a forward roller adjacent the front end of the deck and about which the forward portion of the carrier belt is engaged; said secondary roller means includes an upper guide roller in spaced relationship above said forward roller and about which the front portion of the retaining belt is engaged to direct the front portion of the retaining belt upwardly and rearwardly about the forward half of said forward roller, a front idler roller spaced forward from said forward roller and about which the front portion of the retaining belt extending from said guide roller is engaged and from which the bottom portion of the retaining belt extends.

Claim 7

Dependent Claim 63 words

The slide structure set forth in claim 5 wherein said carrier belt is established of carbet material having a flat back defining its inner surface and a fibrous pile definings it outer surface; ice flakes of said bed of ice at the outer surface of the carrier belt are inter-engaged with the pile whereby the bed and carrier belt are mechanically locked together.

Claim 8

Dependent Claim 40 words

The slide structure set forth in claim 6 wherein the outside surface of the retaining belt is textured and impresses a corresponding texture in the surface of the bed of ice when it is engaged with said bed of ice.

Claim 9

Dependent Claim 151 words

The structure set forth in claim 1 wherein said primary roller means includes a rear roller adjacent the rear end of the deck and about which the rear end of the carrier belt is engaged; said secondary roller means includes an upper roller spaced rearward from the rear roller and about which the rear portion of the retaining belt is engaged and which directs the carrier belt forwardly and downwardly toward the lower portion of the rear roller, whereby the rear portion of the carrier belt and the portion of the retaining belt extending between the rear roller and the rear end portion of the carrier belt define a transversely extending upwardly opening trough across the rear end of the carrier belt into which loose ice flakes, advanced over the rear of the carrier belt, drop to engage the retaining belt for transport forwardly into re-engagement with the bed of ice.

Claim 10

Dependent Claim 63 words

The slide structure set forth in claim 8 wherein said carrier belt is established of carpet material having a flat back defining its inner surface and a fibrous pile defining its outer surface, ice flakes of said bed of ice at the outer surface of the carrier belt are inter-engaged with the pile, whereby the bed and carrier belt are mechanically locked together.

Claim 11

Dependent Claim 40 words

The slide structure set forth in claim 9, wherein the outside surface of the retaining belt is textured and impresses a corresponding texture in the surface of the bed of ice when it is engaged with said bed of ice.
