Field of the Invention

The present indention relates to obstaele courses that people can traverse and otherwise enjoy.

Background of the Invention

Obstacle courses have evolved over the years. Early obstaele courses: included tires that participants had to step into, walls and ropes to climb. Early obstacle courses were located outside, in recent years, obstacle courses can be found inside.

Many of the obstacles are suspended above the floor and span a space. An example of an obstacle includes monkey bars. Other obstacles include swings that the user must step onto and off of to traverse from swing to swing, inclined surfaces to climb, and zip lines. A user traverses the space and the obstacle, If the user loses grip or balance, the user may fall off the obstacle. Users are typically not wearing a safety harness. As a result, a falling user lands in the area below the obstacle,

Various surfaces have been provided underneath obstacles to cushion the fall of a user. A felling user may land on hands, feet, or other body parts, necessitating, a soft surface. Examples of such surfaces include pea gravel, pools of water, foam cushions, blocks or pieces of foam and ball pits. Ball pits are pits with a large number of plastic hollow bails. The balls, bear on a floor surface such as concrete.

It is desired to improve cushioned landing areas and in particular a ball pit landing area,

Description of the Preferred Embodimerit

The obstacle course has one or more obstacles, that traverse spaces or spans of distance. At least one of the obstacles is provided with, a cushioned landing area that, is both, comfortable to laud on arid aesthetically pleasing. The landing area is covered with a ball pit .A user landing on. the landing area, lands in relative comfort on the balls. The balls are transparent or translucent. Lighting is provided, so as to illuminate the balls, and the landins area, thus adding to the visual aesthetics of the obstacle. This lighting is in addition to any ambient lighting over the obstacle course. In addition, a cushioning layer is provided beneath, the balls to further soften landings, and in particular landings where an arm or a leg penetrates into the balls.

The obstacle coarse has: plural obstacle units. Each obstacle unit includes, an, obstacle and supporting structure for the obstacle. In. addition,, each obstacle unit typically includes something to allow for a user to tall safely off ofthe obstacle. For example, a landing area is located: below the obstacle and allows, a user to fall from the obstacle and land saielv and without injury. As another example, some obstacles may provide harnesses that a user wears when traversing the obstacle if the user Mis, the. harness suspends the user above the floor, preventing injury.

Each, obstacle unit also has locations where a user can enter the obstacle unit and leave the obstacle unit Typically, the course is set; up so that a user traverses one obstacle and when leaving that obstacle is positioned so as to traverse the next obstacle. The obstacles are typically arranged so that a user traverses the obstacles in a predetermined sequence. An obstacle unit may share supporting structure and a landing area with adjacent obstacle units.

The obstacle course can be indoors or outside. If indoors, the course is located on an underlying floor structure, such as concrete _* If outdoors, the course is .located- on ground, Ambient lighting is provided, which lighting isabove the landing area and; above the: obstacle course. If indoors/the ambient lighting is typically located along the ceiling . If outdoors the ambient: lighting is typically daylight suppiemented with pole mounted lighting for night operations,

The obstacle course can be on a single ie¥el or on. piural teveis. If oxia single level, each unit is located adjacent to the ground, If on plural. level:s, some units are adjacent to the ground while other units are elevated above the ground. Some: of the elevated, units may provide a landing area and thus provide a supporting floor structure. The supporting floor structure Is elevated above the ground.

For the discussion herein, the term "floor" will be- used to .describe the floor, ground or other underlying: (elevated or not): structure. In. the description, like reference, numbers show like components among; the figures.

Fig 1 shows an exemplary obstacle unit 11. The obstacle unit includes the obstacle 15, supporting structure located around the obstacle and a landing area 17 below the obstacle. Ambient lighting 18 is located, above the obstacle course.

The obstacle 15 is elevated above the floor 19 (see also Fig, 2). The obstacle may be supported above, the floor by the supporting stractere. Alternatively, the obstacle may be supported directly by the floor.

The supporting structure includes vertical posts 21 and overhead beams 23 supported by the posts. In Fig. 1 the ffontmost post: 21 is cut away so as to better view the obstacle 15, in addition, lateral beams 25 may be provided between the posts, at a lower level The posts 21 and beams 25 are covered with cushions to provide soft surfaces against impact. Alternatively, the obstacle can be supported directly by the floor.

An example of an obstacle 15 includes a rope or cable ladder oriented horizontally (shown in Fig, 1 ). The ladder has rope rails 27. the ends of which are secured to the lateral beams 25; the ladder spans from, one lateral beam to another. Rope steps 21 extend between the rails.. The. ladder is elevated above the floor 19 and above the landing area 17. Other types of ladders can. be used, such- as ladders having steps made of boards or logs. Such ladders exhibit movement when a user attempts to cross, increasing the level of difficulty. Ropes 31 or other handholds can be suspended over the. rope ladder, for users to grasp when crossing the ladder.

Another example of an obstacle includes .a zip line having: a line spanning the unit, with a. trolley thereon, The user grasps the trolley and rides aerass the unit. The zip line may be a cable or pipe. The zip line may be sloped downwardly so the user can utilize gravity. Alternatively, the zip line may be horizontal, wherein the user must swing the user's body to develop dre momentum needed to move along the zip line.

Another example of an obstacle includes one or more narrow beams oriented horizontally. The user must maintain balance while stepping on the top surface of the beam. The beam can be fixed, or the beam, can pivot about a point along its length so that the ends move up and down. With the pivoting beam, the beam end is down when the use steps on that end, with the far end raised to an up position. The pivot point for the beam can be located in the landing area 17, Another example of an obstacle includes several swings arranged in a row. Each swing: has a seat suspended fey ropes. The user steps on the nearest swing and then the next swing and so on.

Another example of an obstacle includes a path of stepping areas elevated above the floor. The stepping areas can be flat or nonflat and are spaced apart from one another. The user steps on each stepping area. The stepping areas are: typically small in area, to require the user to maintain balance. The stepping areas can. be mounted to the floor or to a beam suspended by the lateral beams. The stepping areas can, be feed in place or movable.

The landing area 17 is located below the obstacle 15 and above the floor 19. The landing area includes a ball pit. The ball pit has end walls 31 and side wails 33 to form a pit or eontaimnenl space. The end and side walls 31, 33 may be under the lateral beams 25. The walls 31, 33 earn be made of foam covered with a material such as vinyl Such walls are self-standing. The bottom edges: of the walls can be coupled, to a bottom layer, which anchors the bottom edges,

Balls 35 are located inside the walls 31 , 33 or pit area, The balls form a mass that coders: the entire landing area. The mass of balls extends between and contacts the end walls 31 and the side walls 33, The mass ofballs 35 extends to a depth so that; balls are stacked on top of other balls. For example, the balls ean be stacked to a depth of 1-4 feet, (The figures show only a few balls for illustrative purposes.

The balls 35 are hollow spheres with walls typically made of plastic Plastic typically does not break under normal use, The balls; at© several inches in diameter ranging for example: from 1 inches to 5 inches. The balls are typically of a uniform: diameter; however the halls can. be. of different diameters.

The wails of the balls 35 are at least translucent so as to pass light therethrough. The use of the term "at least translucent" means either translucent or transparent and light is allowed to pass, though. An opaque Wall blocks the passage of light therethrough and i s therefore not translucent (and certainly not transparent). In the preferred embodiment,, the balls: are transparent. The balls need not be perfect spheres, but cam exhibit some misshaping, In addition, the wails making up the bails may contain imperfections (for example air bubbles, occlusions, etc,) in the transparency or translneency. The interiors of the balls are empty, being filled with air.

The balls: can he made in several ways. One way is. injection molding of two spherical, halves. The halves are: removed from the molds and then assembled into a ball. The, halves are then coupled together such as by heat welding. Another way is to rotational ly mold the balls..

In the prior art blls in ball pits are made: of opaque plastic, not transparent or translucent plastic. In the prior art, aesthetic appearance is achieved: by having the balls be brightly colored. The bails: in the prior art ball pits are illuminated by lighting: above the ball pit, such as by ceiling lights. Such ceiling lights are common in indoor buildings housing obstacle courses.

A layer of foam 37 or some other cushioning material is provided underneath the balls. The foam is above the floor 1,9 and. forms the bottom of the ball pit. The bottom balls contact the foam. A user may fail from the obstacle and land in the landing area, pusching an arm or l eg through the balls toward the floor. The foam forms a harrier so the user does not directly contact the floor, and further softens the landing. The foam can be uncovered, where the bottom, balls contact the foam directly. Alternatively,, the loam can be covered: with a material such as vinyl

The ball, pit is provided with lighting 41, or light sources, underneath, the mass of balls 35. The lighting illuminates the balls, In, one embodiment, the lighting 41 includes LED strips (see Figs, 2 and 3), Such LED strips 41 have plural individual LEDs arranged along the strip. The. strip forms a backing for the; LEDs and associated wiring to connect the LEDs. The. strips are flexible and are located: on the foam layer, The strips have a low profile and do :not interfere with the operation, of the balls in cushioning a landing, The LED strips extend from one wall to the opposite wall. Plural, strips are: provided^ with the strips spaced apart from each other. The strips can extend between the side walls or between the end walls. In addition, strips can be located on. the side walls 33, _. or on. the end walls 31. The lighting strips are provided with the; necessary electrical power to operate.

The strips 41 can . be located in recesses formed in the top of the foam layer 37 (see Fig. 2), As an alternati ve, the strips can be located on top of the foam layer (see Fig, 4),

Other types of lighting can be provided. For example _* the lighting can include individual. lights spaced: apart from one another. Lighting can also be provided on the side and end walls as shown in Figs, 2 and 3.

The mass of balls 35 cover or obscure the lighting 41 from direct view of the users. Thus, the mass of balls overlay the Iighthig. When, the lighting 41 is iilnminated, the balls 35 illuminate. Even though the bails ob.sc.ure the lighting from direct view, the balls act as lenses (see Fig, 4), with the balls illuminating; and transmitting light 43 to adjacent bails and to the space above the landing area where users can view the light. In particular, the balls 35.A adjacent, to a light 41 are illuminated by the light. Those illuminated balls pass some of the light on to next adjacent balls 35B, which in turn, pass the light on the next adjacent halls, and. so on. The adjacent balls maybe in. direct physical contact with, the source ball, or may be in near proximity thereto. The light is transmitted from ball "to ball at the points where, the balls make direct contact with each other. The light is also transmitted across air gaps 45 between the balls. Because the bails are spherical each, ball, is mostly surrounded by air gaps; the areas of contact with adjoining balls are small In size. The balls transmit the light in all directions. Thus, a user at we: and to the side of the landing area can view the illuminated balls. Each entire hall appears to be illuminated by the light.

4 user attempts to cross the obstacle 15. The user starts at one end of the rmit, steps Onto a ladder rung and attempts to walk, across on the: rungs. The user can grasp the ropes 31 for assistance. As the user approaches and negotiates the obstacle, the user sees the. illuminated balls in the ball pit below. The aesthetic effect is unique; as prior art landing areas lack such lighting,

If the user fells into the landing area, the user displaces: some: of the balls. The balls move, in response to the impact and cushion the fall This displacement is enhanced visually by the illuminated balls. The illuminated balls are easily seen even with ambient, overhead lighting. Such ambient overhead lighting typically is ceiling lights located above the obstacle unit. The space around the obstacle unit need, not be darkened for the illumination in the balls to be seen.

The spacing of the light strips can vary. Preferably, the light strips are spaced sufficiently close to avoid dark, or poorly illuminated areas of bails in the ball pit

Figs. 5 and 6 illustrate other embodiments of lighting configurations, in Fig, 5, the lights 41 are located on the bottom; 37, or floor, of the ball pit, with no lights on the walls 31 , 33 , In Fig. 6, the lights are located on the walls 31, 33, but not on the bottom 37, In Figs, 5 and 6, the bottom is made up of the foam 37.

Thus, the lights can. be located in various ways: in the ball pit. The lights can be located on the bottom 37, en the walls 31, 33, or a combination of on the bottom: and the walls _. Lights located on the bottom can be located on top of the loam or in the foam.

Figs, 7 and 8 illustrate still another embodiment of the lighting Configuration, The lights 41A: are of the LED type, bit instead of strip lights, are non-strip light fixtures. For example wash lights 4IA Qan.be used. Such wash lights are provided with a housing and one or more LED lights. For example, the housing can be disc or can shaped. Mounting hardware can be provided to morint the lights to the walls For example, a mounting bracket can be used to mount each light fixture 41 A to the respective wall. The wall is sturdy enough to support the light. The lights 41 A are: located around Hie periphery of the bail pit with lights on the side wails 33 and the end walls 31 , The lights 41 A, are located. so as to fee underneath, the balls.

The lighting can he white light or have one or more colors. The walls of the balls can be clear so that the halls appear as white (if white lighting is used.). Alternatively, the: walls of the halls can. have color tints, so: that the balls appear colored (for example, blue). The lights can change colors.

Although the lighting has been described as being used hi eQi¾uilction with a foam layer, the lighting can be used without foam. The boiiom of the ball pit would fee the floor 19 or some other material,

The foregoing disclosure and showings made in the drawings are merely illustrative of the principles of this invention and are not to be interpreted in a limiting sense.
