DETAILED DESCRIPTION AND BEST MODE OF THE INVENTION

A children's toy waterslide constructed according to the present invention is shown in FIG. 1, and indicated generally at 10. Waterslide 10 includes a sliding surface 12, a sprinkler tube 14, an obstacle tunnel 16, and a splash zone 18. Sliding surface 12 may be a long narrow sheet of plastic, in the range of 15-25 feet in length and in the range of 25-40 inches wide. For example, sliding surface 12 may be around 22 feet long and 33 inches wide. Sliding surface 12 may be made of any suitable plastic material, such as polyvinylchorhide, polyethylene, polypropylene, etc.
Sprinkler tube 14 extends along one of the long sides of sliding surface 12 and may be configured with a hose fitting to attach a water supply. Sprinkler tube 14 may include a series of spaced-apart apertures that allow water to spray out of the tube when under pressure. The water being sprayed out of the sprinkler tube makes the sliding surface 12 slippery enhancing the play value of the water slide. For example, sprinkler tube 14 will be formed integrally with sliding surface 12.
In the embodiment shown in FIGS. 1-4, sliding surface 12 extends through obstacle tunnel 16 and into splash zone 18. An end bumper 20 surrounds splash zone 18. Splash zone 18 slows a sliding child down near the end of the waterslide because water pools in this area. This deeper water slows down a slider. End bumper 20 may be inflatable and may provide cushion to a slider, as the slider enters the splash zone. Preventing a slider from sliding off the end of waterslide 10, enhances the play value of the waterslide.
Obstacle tunnel 16 may be positioned over a portion of sliding surface 12 prior to the splash zone 18 of the waterslide. Obstacle tunnel 16 includes a front tunnel support 22, a front-tunnel-support connector 24, upper tunnel rails 26, lower tunnel rails 28, and rear tunnel support 30. Obstacle tunnel 16 may be positioned over a portion of sliding surface 12 and extends lengthwise along waterslide 10. Front tunnel support 22 is positioned so that a slider enters the tunnel from this end, and includes two sides interconnected by front-tunnel-support connector 24. Positioned between the two sides of front tunnel support 22, a trigger paddle 32 hangs from a trigger pivot rod 34. Trigger pivot rod 34 may be supported by front tunnel support 22. Trigger paddle 32 extends down into the path of travel of a slider using waterslide 10 leaving a gap of around 5 inches between the bottom of trigger paddle 32 and the sliding surface, as best shown in FIG. 2. Trigger pivot rod 34 may be positioned at a height of around 18-22 inches above the ground. Trigger paddle 32 includes a cord connection point 36 positioned above trigger pivot rod 34 on trigger paddle 32. Connection point 36 moves toward the front of obstacle tunnel 16 as trigger paddle 32 moves toward the rear because connection point 36 is positioned above trigger pivot rod 34.
As shown in FIG. 2, front tunnel support 22 may have an overall height in the range of 20-26 inches and an overall width in the range of 35-50 inches. For example, the overall height of front tunnel support 22 may be around 24 inches and the overall width may be around 45 inches.
FIG. 1 illustrates front tunnel support 22 linked to rear tunnel support 30 by the upper and lower tunnel rails. Specifically, upper tunnel rails 26 extend between upper portions of the front and rear tunnel supports. In the same manner, lower tunnel rails 18 extend between lower portions of the front and rear tunnel supports.
Rear tunnel support 30 provides a platform for dump bucket 38. Dump bucket 38 is configured to pivot about a dump-bucket pivot rod 40. Dump-bucket pivot rod 40 extends through dump bucket 38 and is supported on each end by rear tunnel support 30. FIG. 4 shows rear tunnel support 30 supporting dump-bucket pivot rod 40. Dump bucket 38 includes a dump-bucket connection point 42 positioned on the underside of the dump bucket below where pivot rod 40 extends through dump bucket 38.
A cord 44 connects from connection point 36 on trigger paddle 32 to dump-bucket connection point 42 on the bottom of dump bucket 38, as shown in FIGS. 1, 3A, 3B, and 3C. Dump-bucket 38 may be tipped over by a pulling force applied to dump-bucket connection The length of cord 44 is sized to include a certain amount of slack between trigger paddle 32 and dump bucket 38. A child sliding through obstacle tunnel 16 travels at a speed in the range of 2 to 10 miles per hour. The slack in cord 44 provides a delay between a child's impact with trigger paddle 32 and the pulling of cord 44 to dump the contents of bucket 38. The delay enables the child to slide through the tunnel and arrive directly below the bucket as its contents pour out, dunking or soaking the child from above.
Obstacle tunnel 16 is configured to dump water onto a slider, as best illustrated by the cut away views of FIGS. 3A-3C. FIG. 3A shows obstacle tunnel 16 prior to a slider entering the tunnel. Trigger paddle 32 hangs essentially straight down toward the ground. Cord 44 connects trigger paddle 32 with dump bucket 38 with a slight amount of slack.
A sliding child enters obstacle tunnel 16 at the front tunnel support 22, as shown in FIG. 3B. The slider impacts trigger paddle 32 upon entering obstacle tunnel 16 causing the trigger paddle to swing up rearwardly out of the sliders path. The up rearward swing of trigger paddle 32 causes cord 44 to tighten and pulls on bucket connection point 42.
The slider continues through obstacle tunnel 16 as trigger paddle 32 continues to swing up out of the slider's path. After the slack has been removed from cord 44 it pulls on bucket connection point 42, causing the lower portion of bucket 38 to move and tipping bucket 38 over. Obstacle tunnel 16 and cord 44 are sized in length so that the contents of bucket 38 spill out at the rear of obstacle tunnel 16 at approximately the same time as a child is exiting the tunnel, as best shown in FIG. 3C. Obstacle tunnel 16 may range in length from 25-50 inches, and may be around 41 inches in length.
Turning to FIG. 5, another embodiment of a waterslide according to the present invention is shown, indicated generally at 50. Waterslide 50 includes a slide surface 52 and a sprinkler tube 54 extending through an obstacle 56 into a splash zone 58. An end bumper 60 cushions a slider as they reach the end of waterslide 50.
In the embodiment depicted in FIG. 5, obstacle 56 includes a “limbo stick” or stick 62 extending across slide surface 52 in a slider's path. Obstacle 56 also includes vertical support members 64 and stick holders 66. Stick 62 is sized to fit on vertical support members 64 and extend across slide surface 52. Support members 64 and stick holders 66 positioned on each side of slide surface 52 support distal ends of stick 62, as shown in FIG. 5.
Vertical support members 64 may have three different sets of stick holders 66 extending rearward and slightly upward from vertical support members 64, as shown in FIGS. 6 and 7. Each set of stick holders 66 may be positioned to hold stick 62 at a different height above slide surface 52.
This construction enables children to compete with one another to see who can slide on waterslide 50 underneath stick 62 without knocking the stick off stick holders 66. As a child travels along waterslide 50 between vertical support members 64, the goal is to remain low enough to slip under stick 62. Stick 62 may be knocked off stick holders 66 without knocking over vertical support members 64 because the stick rests on the backside of vertical support member 64. As a child moves under stick 62 any contact with the stick will cause it to move upward and rearward dislodging the stick from holders 66. Children can then reposition stick 62 to a lower set of stick holders 66 and continue competing.
As shown in FIGS. 8 and 9, another embodiment of a waterslide according to the present invention is shown, indicated generally at 70. Waterslide 70 includes a slide surface 72 and a sprinkler tube 74 extending through a set of obstacles 76 into a splash zone 78. An end bumper 80 cushions a sliding child who reaches the end of waterslide 70.
The set of obstacles 76 may be inflatable bowling-pin-type like bodies. The set of obstacles 76 may be arranged to form an obstacle course that a child may slide through. Obstacles 76 may include indicia printed thereon so that they resemble asteroids or other objects, such as characters, or animals, etc. A child may position obstacles 76 anywhere along slide surface 72. A sliding child then acts as a human bowling ball traveling along waterslide 70. The child may attempt to knock down all of the obstacles 76, or may try to avoid the obstacles during travel down along waterslide 70.
