resistant material such as plastic, laminated plastics or other suitable material.
A further important object of the present invention is to provide a slide or chute which is durable and capable of longer services, constructed of a single piece thereby providing no separate parts to break, wear or corrode, easy to assemble and extremely inexpensive to manufacture.
Other objects of the present invention will reside in its simplicity of construction and adaptation for use with various types of supporting frame structures.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure l is an exploded group perspective view illustrating the sliding chute of the present invention in association with a supporting frame structure;
Figure 2 is a longitudinal sectional view taken along the center of the sliding board illustrating the relationship of the chute to the supporting frame; and
Figure 3 is a transverse, vertical sectional view taken substantially upon a plane passing along section line 3-3 of Figure 1 illustrating the structural details of the chute.
Referring now specifically to the drawings, the numeral 19 generally designates the sliding board or chute of the present invention for mounting upon a supporting frame generally designated by the numeral 12.
The supporting frame 12 includes a pair of side rail members 14 which have depending V-shaped legs 16 formed on one end thereof with the free ends of the legs 16 being interconnected by a transverse member 18. The other end of the side rails 14 is connected to vertical supporting members 26 having transverse members 22 disposed therebetween in vertically spaced relation thereby forming a ladder with the upper ends of the vertical members 2% terminating in forwardly curved hand rails 2 and the lower ends of the vertical members 20 having a transversely elongated base member 26 having brace means 28 extending upwardly and inwardly inclined from the outer ends of the transverse member 26 to the vertical members 21) thereby forming a support for one end of the frame rails 14 for retaining the same in elevated position.
The chute 14] includes an elongated bedway 30 which forms a load supporting portion and which has a slightly concavely curved upper surface so that children sliding downwardly on the chute 10 will be disposed substantially in the center thereof.
The outer edges of the bedway 39 are provided with inverted U-shaped side guide rails 32 which terminate in outwardly flared and rounded edges 34. The undersurface of the side guide rails 32 forms a downwardly opening channel 36 with the inner and outer surface of the guide rail 32 being substantially cylindrical in crosssectional shape whereby the channel 36 will frictionally grip the cylindrical pipe side rails 14 of the frame 12.
The opposite end of the bedway 30 is provided with depending terminal ends 38 having an outwardly flared free edge iii for engagement over the transverse member 18 as well as the uppermost transverse member 22 thereby positively positioning the chute 10 on the supporting frame 12 with the channel 36 frictionally engaging the side rails 34 for retaining the chute it on the supporting frame 12.
It will be understood that other types of supporting ladders may be employed such as a swing or the like whereby the rails 14 and the transverse member 18 as Well as the transverse member 22 will form a rigid support for the one piece chute it) which is self n'gidifying due to the concavity of the bedway 30 and the cylindrical construction of the guide rails 32 and the chute It may be constructed of any suitable plastic or laminated plastic material or certain types of metal material constructed in accordance with well known manufacturing procedures thereby assuring a minimum manufacturing cost and eliminating all assembly problems and possible breakage, loss or damage to various assembly elements which is normally encountered when assembling articles of this nature.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
What is claimed as new is as follows:
1. A playground sliding board comprising a supporting frame of one-piece construction including a pair of inclined side frame rails having downwardly extending V-shaped legs at the lower end thereof, an interconnecting transverse member between the ends of said legs, said side frame rails having elongated downwardly extending legs at the upper end thereof for supporting the side frame rails in inclined position, a plurality of transverse vertically spaced members interconnecting the elongated legs, a chute of one-piece construction mounted on said frame, said chute including a load supporting portion and a pair of side guide rails, said guide rails being generally U-shaped and inverted for forming downwardly opening channels for receiving said side frame rails, said load supporting portion having downwardly curved ends for grippingly engaging the remote edges of the transverse member between the ends of the V-shaped legs and the upper of the transverse members between the elongated legs, each of said side guide rails on the chute terminating in outwardly flared edges, said frame rails being generally cylindrical in shape with the downwardly opening guide rails frictionally gripping said side frame rails, said chute being of one piece construction of corrosive resistant material, said load supporting portion of the chute being curved transversely in a concave manner for guiding the movement of children thereon and rigidifying the chute.
2. A sliding board construction comprising a supporting frame, and a chute mounted on said frame, said frame including a pair of spaced parallel inclined side rails, means supporting the upper ends of said. side rails, said supporting means including a transverse rail member, each supporting bedway, an upstanding side member on each side of said bedway, each side member being an inverted U-shaped member defining a downwardly opening channel for grippingly engaging the side rails of the frame, each end of the bedway being curved downwardly for grippingly engaging outer surfaces of the transverse rail of said'side rails including a downwardly extending V-shaped leg on the lower end thereof, said V-shaped leg having one leg portion continuous with a frame rail and the, apex thereof adapted to engage a supporting surface, the other leg portion of the V-shaped leg extending in diverging relation to the first mentioned leg portion, a transverse member interconnecting the router ends of the V-shaped legs, said chute including an elongated load members. r
