Field of the Invention The present invention relates in general to a new structure for waterslides, specifically a structure for waterslides providing more thriller experience with its unique shape and functions which are used for fun and excitement in waterparks.

Background of the Invention Waterslides also known as flume, water chute, or hydroslide are popular ride attractions for waterparks, theme parks, and tourist hotels. Waterslides are not just a simple feature for children to play or cooling apparatus for summer heat, they are also irreplaceable fun tool for all kind of people.

In a typical waterslide a rider or a group of riders slides downwardly from higher elevation to lower elevation on a water film which is cooling the riders and lubricating the sliding surface. A rider who is sliding alone can slide on a mat, tube, raft, boat or his/her own body but a group of riders generally uses boat or different ride vehicles except some special rides. Pump systems are generally use for recirculating water from outlet to inlet thanks to that the mentioned water film is formed continously on the inner surface of the waterslide. Surface with the water film let the riders or ride vehicles speed up. This is not the only thing which is affecting the speed. Speed of a rider is changeable respect to so many parameters on waterslides. Such as, rider’s weight, slope of the sliding surface, water speed, design of the slide (turns, twists and so on), elevation level on the starting point. Today’s waterslides are very popular and common choice for amusement parks.

Demand on the related market is so large. So many private people and juristic persons making investments on this area. Municipalities are the well-known example of this. Park patrons are generally focusing the number of coming people to their waterparks. The key point of increasing that number is about using new and more thriller water slides. If the waters lide is new and provides more thrilling and exciting experience, the waterpark will be visited by much more people. Therefore, the slide manufacturers are always in the search of new designs and concepts.

In the background of the art, some popular design structures are in the shape of a funnel and bowl. The mentioned structures have a single point rider cnlcrcncc. One problem with the the single point entrance is that it significantly limits the alternative paths and trajectories of the riders. Riders move on just one main direction from entrance to exit. Another problem with the the single point entrance is arising from the speed variation of the riders. In a walerslide heavier riders gain higher speed and as a result riders climb higher in the walerslide structure. Therefore the single point entrance must be specified regarding fastest riders to prevent tumbling on the inner surface of Ihc walerslide structure. As a consequence slow riders (liglher riders) are not able to gain good/lhrilling experience from the waterslides.

Present invention having a unique shape and multipoint lateral rider entrance provides all riders having variable of speeds with good, thrilling ride experience from waterslides.

Detailed Description Embodiments of the present invention relates to a structure for waterslides comprising a body (1) in a form of prolate ellipsoid compressed/flattened from top (T) and bottom (from its equator); having side walls (2) and a bottom wall (3); and an open front end (4) (a pole) for rider exit; a lateral rider opening (5), preferably facing the open front end (4), for connecting at least a waterslide disposed almost parallel to at least a side wall (2); where at least a part of the side wall (2) is protruding in a form of a substantially half tubular wall (6) an end of which is connected to the rider opening (5).

In one embodiment of the structure for waterslides which is applicable for all embodiments, the lateral rider opening (5) is adapted to accept one or more rider with or without a ride vehicle such as boat.

In one embodiment of the structure for waterslides which is applicable for all embodiments, the body (1) has a back end (7) which can be close for mounting special effect (light and/or sound) equipment on it or open for increased ventilation and/or showing environment/sky to the rider. In one embodiment having open back end (7), at least one part of the edge of the open back end (7) curved for providing a guide to water. The open back end (7) may be round, oval, eliptical or oblong form in shape.

In one embodiment of the structure for waterslides which is applicable for all embodiments, the open front end (4) may be round, oval, eliptical or oblong form in shape.

In one embodiment of the structure for waterslides which is applicable for all embodiments, the open front end (4) and open back end (7) substantially have the same form in shape.

In one embodiment of the structure for waterslides which is applicable for all embodiments, the top of the body (1) is open for increased ventilation and/or showing environment/sky to the rider.

In one embodiment of the structure for waterslides which is applicable for all embodiments, at least one part of the edge of the open front end (4) is curved for providing a guide to water.

In one embodiment of the structure for waterslides which is applicable for all embodiments, the structure for waterslides comprising a discharge/pour spout (8) for providing a guided rider exit connected to edge of the bottom wall (3). The discharge/pour spout (8) preferably has a V or O or U cross section and preferably side wall (2) edges of which are curved for providing a guide to water. End of the discharge/pour spout (8) is for connecting a waterslide or a pool or another waterslide structure.

In one embodiment of the structure for waterslides which is applicable for all embodiments, diameter of the front end (4) of the body (1) is bigger than the back end (7). In other word, diameter of the body (1) is getting smaller progressively from the front end (4) to the back end (7). Angle between the bottom wall (3) and a surface tangent to the front end (4) (a), angle between the top (T) surface and a surface tangent to the front end (4) (b), angle between a line passing through center of the substantially half tubular wall (6) and a surface tangent to the front end (4) (g) may be selected to determine path of a rider.

In all embodiment of the protruding part of the side wall (2) providing the substantially half tubular wall (6) elongates substantially parallel to the side wall (2). Protruding part / substantially half tubular wall (6) form constitutes a multipoint rider opening (5) (entrance inside the curved body (1) (prolate ellipsoid form)) by enlarging lateral slide entrance. The said multipoint rider opening (5) provides substantially different entry points for riders with different speeds where riders follow substantially different paths and trajectories which grants thrilling and safe ride. When a rider with or without ride vehicles enters the structure from the lateral rider opening (5), paths and trajectories of the rider differs regarding the speed of the rider. Faster rider moves forward longer through inside the substantially half tubular wall (6) than slower riders (See Figure 9). After, the rider moves through inside the curved bottom wall from the different part of the substantially half tubular wall (6). Inside the curved buttom wall, the riders is exposed to a back and forth (oscillating) motion between side walls (2) and/or spin motion. During the back and forth motion where the rider is getting slower, the riders also moves from back end (7) (and side walls (2) of the body (1) inside) to the open front end (4) where through the rider exits. In one embodiment of the structure for waterslides, the rider exits through discharge/pour spout (8).

In one embodiment of the structure for waterslides which is applicable for all embodiments, at least a part of the side wall (2) is protruding in a form of a substantially half tubular wall (6) an end of which connected to the rider opening (5) and the at least a part of the other side wall (2) (opposite to the afforamentioned side wall (2)) is protruding in a form of a substantially half tubular wall (6) and not connected to a rider opening (5) for such as providing symetry. In one embodiment of the structure for waterslides which is applicable for all embodiments, at least a part of the both side walls (2) are protruding in a form of a substantially half tubular wall (6) an end of which connected to the rider opening (5) (Figure 14). In this embodiment, the structure has two substantially half tubular walls both end of which are connected to separate rider openings for connecting at least a waterslide. Thus, riders are able to have sliding experience from both side of the structure which can be a reason for preference for left-handed or right-handed riders. On the other hand, having two substantially half tubular walls both end of which are connected to separate rider openings for connecting at least a waterslide provides versatility to the waterparks. During out of service periods in one waterslide which is for connecting the one of the rider opening, the riders can continue to use the structure from the other rider openning which is for connecting an other waterslide. In this way, the structure is always ready to use in the case of maintanance, renovation or malfunction etc. on one of the waterslide which is connected to one of the rider openning of the structure. In one embodiment of the structure for waterslides which is applicable for all embodiments, the structure for waterslides comprises speed control systems such as (not limited to) nozzle systems, water jet systems, pneumatic systems, air-based systems for controlling velocity of the rider and also diversifing more alternative sliding paths and/or specifying more accurate and more safe sliding paths.
