Claims
What is claimed is:
1. A play slide comprising an inclined generally planar slide
member adapted for superposition over a stairway, a plurality of
rest members carried in downwardly facing relation on the underside
of said slide member at horizontally and vertically spaced
locations for resting engagement with nether stair treads, side
members extending along respective longitudinally margins of said
slide member, a generally level terminal portion on the lower end

extension of a respective one of said upright walls, and depending
extensions on said upright walls extending to said rest members for
reinforcing the latter, each said rest member extending between an
opposite pair of said depending extensions.
2. A play slide according to claim 1, in combination with a
plurality of nether strut members each upstanding between an
adjacent pair of rest members and laterally opposite depending
extensions, to provide effective reinforcement.
3. A play slide according to claim 2, in combination with
frictional surface members on the undersides of said rest members
for frictional bearing engagement with the stair treads to resist
horizontal displacement therefrom.
4. A play slide according to claim 1, in combination with
frictional surface members on the undersides of said rest members
for frictional bearing engagement with the stair treads to resist
horizontal displacement therefrom.
Description
BACKGROUND OF THE INVENTION
While there have, in the past, been proposed a wide variety of
children's toys and playthings, including many different
constructions of slides, the prior art has not provided a
children's play slide for use on a stairway which is sufficiently
simple, safe, economical and durable to achieve wide commercial
acceptance.
SUMMARY OF THE INVENTION
It is, therefore, an important object of the present invention to
provide a children's play slide which overcomes the above-mentioned
difficulties, being capable of easy and convenient usage in
position on a pre-existing stairway, and which is extremely simple
in structure, requiring a minimum of parts, capable of economic
manufacutre for sale at a reasonable price, and which is durable,
reliable and substantially maintenance-free throughout a long
useful life.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a top perspective view illustrating a play slide of the
present invention in operative association with a stairway.
FIG. 2 is a longitudinal sectional elevational view taken generally
along the line 2--2 of FIG. 1 showing the slide apart from the
stairway.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now more particularly to the drawings, a play slide of
the present invention is shown therein and generally designated 10.
In FIG. 1, the slide 10 is superposed on a stairway 11, which
includes a plurality of risers 12 and treads 13, in the
conventional manner.
While it is appreciated that the instant slide may be fabircated of
any suitable material, and manufactured by any desired method, all
without departing from the instant invention, it is believed that
the instant device admirably lends itself to economic manufacture
by thermoforming component parts of suitable thermoplastic
material, such as polystyrene, or the like, and permanently
assembling the parts by any suitable means. Of course, the
materials and mode of manufacture are disclosed by way of
illustration and example, without limiting intent.
Considering the slide 10 in greater detail, the slide structure
includes an inclined, generally planar slide member or plane 15
adapted to support a sliding child. The slide member or inclined
plane 15 may have its upper terminal or end region 16 smoothly
curved slightly downwardly out of the plane of the member, and have
its upper end edge 17 smoothly rounded, for convenient and safe
access by playing children. Further, the lower terminal portion or
end region 18 of the slide member or inclined plane 15 may be
smoothly curved slightly upwardly out of the plane of the slide
member toward a generally horizontal disposition, having its lower
or free end edge 19 smoothly curved, all for the safe discharge of
sliding children. That is, the relatively horizontal disposition of
lower terminal portion 18 effectively retards the leaving velocity
of a sliding child, while the smoothly curved lower end edge 19
prevents scratches and bruises to the children.
As shown in FIG. 1, the inclined slide member 15 is disposed in
superposed relation over the stairway 11. Carried on the underside
of the slide member 15, extending laterally thereacross, are a
plurality of generally horizontally disposed, downwardly facing
panels or rest members 21 located for respective resting engagement
with the nether stair treads 13. That is, the several rest members
21 are carried on the underside of the slide member 15 is a stepped
or horizontally and vertically spaced relation.
Additionally, a plurality of generally upright or vertically
disposed strut members or panels 22 are arranged in horizontally
and vertically spaced relation with respect to each other on the
underside of and generally laterally coextensive with the slide
member 15, each extending vertically between an adjacent pair of
rest members 21. The rest members 21 and strut members 22 are
proportioned and sized for respective conforming extent along the
treads 13 and risers 12 of the stairway 11.
Additionally, a frictional layer or coating 23 may be provided on
the underside of each rest member 21 for frictional bearing
engagement with the adjacent stair tread 13, to resist horizontal
displacement relative to the stairway.
By reason of the relatively horizontally extending lower terminal
portion 18, the latter will be understood to project horizontally
away from the stairway 11 and also away from the supporting nether
structure 21, 22. In practice, the terminal portion 18 may extend
in spaced relation over the floor region adjacent to the lowest
step of stairway 11. Toward supporting the terminal portion 18 of
slide member 15, a pair of side strut members 25 depend from
opposite sides of the terminal portion for bearing engagement with
the floor. The side strut members 25 may extend in laterally spaced
parallelism with each other, effectively defining side wall
portions having their lower edges in supporting engagement with the
floor surface.
In addition, a pair of side members, walls or rails 26 extend
longitudinally along respective side edges of the slide member 15,
upstanding generally vertically therefrom, to provide safety
barriers or walls confining a sliding child to the upper surface of
slide member 15. The side members or walls 26 may extend vertically
above the slide member 15 a substantial distance, say 8 or 9
inches, to insure safety to the young users. However, the side
members may be of other suitable height, if desired. In practice,
the side members may each define a side wall, and further provide a
coplanar extension of the respective side strut member 25. Of
course, the upper edges of the side members or walls 26 are
preferably smooth and rounded, as are all exposed surfaces, to
prevent injuries.
In addition, each side member, rail or wall 26 is rpovided with a
plurality of depending extensions 28, which depending extensions
may be considered as of generally right triangular configuration
having horizontal lower edges and extending to the adjacent nether
rest member 21 for structurally reinforcing the latter. That is,
the depending side member extensions 28 are disposed vertically,
substantially coplanar with the associated side member or wall,
each depending along an adjacent strut member 22 and terminating at
the adjacent nether rest member 21.
From the foregoing, it will now be appreciated that the present
invention provides a unitary sliding board construction which is
extremely simple to use, being removably placed on a stairway in
conforming interfitting relation therwith, and is conveniently
capable of portability and storage, being entirely safe in use and
requiring no tedious erection and dismantling.
Additionally, there may be provided, say for very small children, a
pillow or pad 30 for location on the floor adjacent to the lower
end of the slide 10. Such a pillow or pad may be of foam rubber or
other suitable consturction, to provide a soft landing for
relatively small children.
Although the present invention has been described in some detail by
way of illustration and example for purposes of clarity of
understanding, it is understood that certain changes and
modifications may be made within the spirit of the invention.
