Restriction or limitation if any referred to in the specification, is solely by way of example and understanding the present invention.
The present invention teaches a children’s play system so constructed that its form, size and play content can easily be varied. It consists of 5 primary parts named as Part 1,Part 2, Part 3, Part 4 and Part 5, and a plurality of auxiliary parts. Out of these, Part 1, Part 2 & Part 3 are the three major parts which are unique and innovative.
These (Part 1, Part 2 and Part 3) are constructed to incorporate three main features:
1. Inscribed play (Application: Part 1, 2 & 3)
2. Inverse symmetry (Application: Part 1, 2 & 3)
3. Underneath slide (Application: Part 1 & 2)
These different parts can be arranged in series at suitable height to increase the height and the length of the overall play slide. The parts are designed in such a way that when arranged in series at suitable heights, they form continuous stairs and slide and/or

only continuous curved slide. The parts are made from either plastic using hollow rotomolding process or of steel structure & sheets or composite plastic. Undercuts & ribs are provided for adding strength to the part, though the design & size may change for better strengths, manufacturing ease and for adhering to playground standard without compromising and being based on the above three concepts.
Part 1, Part 2 & Part 3 are of unique design and are adapted to form inclusive and different play systems when they are arranged in suitable different ways.
The play system has unique play value and aesthetics that the prior art doesn’t have.
The provision of reverse symmetry application, underneath slide, inscribed play and multifunctional single part is unique and is not provided by any system of prior art.
The parts are designed for manufacturing from rotomolding / rotational molding process which may or may not include reinforced steel structure and / or multilayer thickness wall and / or application of filling foam.
The parts are stationary and do not move or manipulate relative to each other without external forces.
- Parts can be inter locking/ self-engaging/ press fit type with inter connectible slots suited for the use of other metallic / plastic extruded/ molded/ beveled/ interlocking block/s of any shape/s.
Inscribed play – This involves making a play system part which has an outer shape/surface which is different from its inside play shape/surface. In part 1 & part 2, the actual play surface (tunnel / tube slide and/or tube slide landing) has a different shape (tube / cylindrical / curve tube and / or curve tunnel) as compared to the outer rectangular box shape of the parts. Reference is made to figures 1 to 14.

Figures 1, 2, 3 and 4 show the isometric, sectional and orthographic views of Part 1. It has been provided with step formation (1), inside tube slide formation (2) and slit (3). Figures 5 and 6 show an arrangement # of two pieces of Part 1 in series. They show how the step (1) and the tube slide (2) are being formed. Figure 7 is an arrangement with three Part 1 pieces showing further progress.
Figures 8, 9, 10 and 11 show similar details of Part 2, according to the present invention.
Figure 12 shows another arrangement arrived at by combining both part 1 and Part 2 pieces, both in the straight and reverse configurations, while figure 13 shows its sectional view.
Figure 14 shows yet another arrangement of both Part 1 and Part 2 pieces, in straight and reverse configuration.
In Part 3, the play surface (curved slide) has a different shape (curved slide) than that of the outer side (rectangular box shaped cuboids). Here too, it is clear that the play surface / shape is inscribed within a different outside shape (here, a rectangular box cuboid).This is shown in figures 15 to 21.
Figures 15, 16 and 17 depict isometric, inverted isometric and third angle projection of all faces of Part 3, where the curved slide (4) is clearly shown.
Figure 18 is an isometric view of two pieces of Part 3 showing how they are connected to form aright hand turn spiral slide (4), while figure 19 is a top view of two pieces of Part 3 showing formation of the right hand turn spiral slide.
The same part, i.e. part 3 can also be connected in reverse configuration to form a left hand turn spiral slide (5). This has been shown in figure 20 (isometric) and figure 21 (top view).

Inverse Symmetry – Part 1 and Part2 provide for reversing the part for the same or different function. In Part 1, identical staircase has been provided both above and below the tunnel / tube slide and designed in such a way that the part when reversed upside down still serves the same purpose and looks exactly the same. This provides inverse symmetry, though the scope of the invention includes asymmetry where the staircase above is not identical to the bottom which may/ may not be same and / or may/ may not constitute different playing and / or accessing and / or thrilling surface.
In Part 2, the top & bottom surfaces of the part serve the same purpose and act like a platform for standing and/or halting or both when reversed and vice versa. But it is so constructed that it serves different functions of both landing and / or slide entry module when arranged upside down and vice versa. The current design involves inverse symmetry only from the functional point of view. Refer Fig. 8 to 14.
Part 3 however provides for reversing the part for a different function. In this part, the part is constructed in such a way that the part, when reversed upside down, serves the same purpose of spiral / curved slide but in different direction of sliding. Refer Fig. 15 to 21.
Underneath slide - Part 1 and Part 2 are constructed to provide a sliding play surface (2) below the staircase (1). Part 1, part 2 and Part 3 need additional parts to be connected to these parts for accessing the underneath slide & for accessing the staircase from ground. No evidence of part 3 in Fig.No.1 to 14
Figure 22 shows a sample arrangement # of part 1(1no) & part 2 (2 nos) pieces to make Platform 1 and Platform 2.
Part 1, Part 2 &Part 3, along with other parts, form the modules of the Multi Activity Play System according to this invention. When such parts are arranged in different ways, they create new forms of the Multi Activity Play System as new play equipment.

In this arrangement, the child needs to climb to the platform 1 with the help of climber module, as shown in figure23, and reaches Platform-1 (Landing module / Entry module WHEN reversed) top surface. The child has to climb the series of staircase formed due to one or more Part 1 pieces arranged at suitable height and reaches Platform -2 (Entry module / Landing module WHEN reversed) top surface. To access the underneath tube / tunnel slide, the child has to reach Platform-3, shown in figures24 and 25, via modular spiral / curve slide arranged at a suitable height.
MATERIALS & MANUFACTURING:
Part 1, Part 2 & Part 3 may be manufactured using MS/SS Aluminum steel and / or plastic/ ppe/ hdpe/ nylon/ nylon reinforced polyethylene/ any other suitable material available & suitable for the product.
• If manufactured using steel as prime component, the part may consist of structural
elements like channels or angles or pipes or plates or any combinations with steel
sheets.
• If manufactured using composite plastic (FRP) for external appearance, the part
may consist of Steel/ Structural elements or composite fiber reinforced plastic parts
suitably mated or fastened or combination of both to form single Aluminum part.
• If manufactured using plastic (Roto molding process) for external appearance, the
part may consist of Steel/ Aluminum Structural elements or plastic parts suitably
mated or fastened or combination of both to form single part.
If manufactured using Aluminum as prime compound, the parts may consist of Aluminum Structured elements like channels or angles or pipes or plates or any combination with Aluminum & or/ Plastic Sheets, or both to form single parts.
Nomenclature of the parts, with reference to figures 22 to 26:

Platform 1 – Top surface of PLAYKON 1 – Part 2 (Landing module / Entry module when reversed)
Platform 2 – Bottom surface of PLAYKON 1 – Part 2 (Entry module / Landing module when reversed)
Platform 3 – Separate part (Not as per the three basic concepts)
A = Climber
B & D = PLAYKON 1 - Part 2
B = PLAYKON 1 – Part 2 (Landing module / Entry module when reversed)
C = PLAYKON 1 - Part 1
D = PLAYKON 1 – Part 2 (Entry module / Landing module when reversed)
E & F = PLAYKON 1 - Part 3
H & I = PLAYKON 1 - Part 3 reversed
G = Platform 3
As shown in figures 26 and 13, after reaching Platform-3, the child can access the tube / tunnel slide through entry module / landing module WHEN reversed and the Part 1 arranged in series at a different height, and then can slide out through the Landing module / Entry module WHEN reversed.
It is clear from the above explanation that the present invention provides a play system involving multiple activities like hiking using climber, climbing using staircase (Part 1), observing using platform, curved sliding using spiral slide & straight sliding using main tube / tunnel (Part 1) in a single play system. Moreover children using the system can be made to explore this new play by frequent re-arrangement of the parts. Their interest in the play station is thereby maintained for long periods. This feature is different from all conventional slide plays of the prior art.

Figures 26 and 27 show top view of an arrangement wherein the parts are marked, and its isometric view respectively.
The activities of the child related to the different constituent parts are as under:
A to B = Hiking
