BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a game to be played by opposing teams or players while bouncing or jumping on a trampoline bed surface enclosed by a caged frame structure and rules for governing the same.
2. Description of the Related Art
Traditionally, the trampoline with a bed surface has been used for a variety of recreational and athletic purposes, such as jumping, exercising, performing acrobatic and gymnastic feats or stunts above the trampoline bed surface, and playing different types of games thereon. Many games have been played on trampoline bed surfaces with a net member stretched across it and being removably secured thereto, such as volleyball, basketball, soccer, badminton, to name just a few.
Prior art games have been created for play on a trampoline with a ball-type net suspended above the trampoline bed surface with a ball member being hit or thrown over the net by users or players to score or compete against one. Such prior art games are disclosed and described in U.S. Pat. Nos. 3,201,126, 3,312,471, 4,433,838, 4,569,515, 5,833,557, 6,988,967 and U.S. Publication No. 2009/0023558, to name just a few.
As a result of careless use of trampolines and poorly designed and manufactured structures, many personal injuries have occurred. Such injuries resulted from a user jumping to close to the edge of the trampoline bed surface and falling off, striking the fame, a tree, the ground, concrete surface, or another hard surface positioned proximate the trampoline's area or boundary. This has been a major concern for many trampoline enthusiasts and manufacturers.
In order to overcome the above injury concerns, trampolines have been designed and made with enclosed flexible fences, nets or framed caged structures that surround the perimeter of the trampoline's bed surface. In these types of enclosed trampolines, any user that plays or jumps on the trampoline bed surface will always be maintained on the bed surface and never fall off the edge and injure themselves. Likewise, because the enclosure is made of a flexible material, such as netting, mesh, or a framed caged structure, the enclosure will also prevent a user or player from harmfully impacting the trampoline's frame or other hard surfaces. In this manner, the enclosure will greatly increase the safety of the trampoline.
Furthermore, the trampoline with the enclosure allows users or players to play a variety of games using the enclosure and other equipment, such as balls, goals, nets, to name just a few. Accordingly, there is a need in the art for various trampoline games that interest older users and will include, for example, sports and sporting events.
Moreover, one disadvantage of trampolines is that they can take up large areas of space. Some sports and recreational activities, on the other hand, often require large open spaces, such as fields, courts, etc., in order to be played properly. People often can not play or practice sports in the same area as the trampoline for fear that the trampoline will interfere with the game.
It has often been recommended by trampoline manufacturers that only one person at a time should jump on the trampoline bed surface, while others await their turn. It would be a significant advancement in the art to provide a new, useful and exciting type of trampoline device, which permits a variety of other sports and recreational activities to be played or practiced in the same area while the trampoline is in use. Such a device is disclosed herein.
The disclosed invention provides a unique and improved ultimate trampoline cage and ball device that is much safer with a better designed and sturdier caged structure.
SUMMARY OF THE INVENTION
The present invention is a trampoline and ball caged structure game device in which one or more persons or players can participate in playing a particular type of game.
According to one aspect of the present invention there is provided a unique trampoline and caged ball game structure that includes a single conventional Olympic sized trampoline bed that is connected to a frame structure by a plurality of spring members. The trampoline bed is preferably made of recreational trampoline material, such as woven polypropylene. Also, the trampoline bed can be made from various other types of flexible materials such as, canvas, nylon and other similar woven-like fabrics. Preferably, the bed surface may comprise a single sheet of woven polypropylene or it may comprise a web woven of strips of such material, if desired. The frame structure has a pair of end sections and a pair of side sections. Each end sections and each side sections have a pair of spaced apart socket receiving portions mounted at an underneath portion thereof. Each socket portion can be secured by welding or bolting thereto. Other types of mechanical securing means may be utilized, if desired. Further, the frame structure includes four substantially U-shaped support legs having a pair of upper ends. One of the upper ends of each of the four legs is removably secured to one of the socket portions of the end sections and the other upper ends of the four legs are removably secured to the socket portions in the side sections. Once the legs are attached they are oriented at an angle relative to side and end sections. This orientation provides a sturdy balance relative to a ground surface.
According to another aspect of the present invention, the trampoline bed is enclosed by a stretched spring suspended cage structure with a preferred dimension of 12′×6′×12′. The cage structure is preferably made of a continuous open-ended sheet of the same material that the trampoline bed is made from, which is folded at four different areas defining four-cornered reinforced folds. Each of the reinforced corner folds of the continuous open-ended sheet forms a pair of end wall panel sections and a pair of side wall panel sections there between.
Also, the pair of side wall panel sections includes an intermediate reinforced stitched seam that runs substantially the entire length of the pair of side wall panel sections. The reinforced stitched seam has a plurality of spaced apart reinforced holes disposed therein.
The four-cornered folds are suspended by a plurality of selectively spaced springs with one end thereof connected to the four-cornered folds via a reinforced hole therein or connected to one end of an S-shaped hook with the other end being connected to the reinforced hole. The other ends of the plurality of selectively spaced springs are connected to a plurality of aligned and selectively spaced extending clamping tabs that are removably secured to a pair of elongated corner pipes or poles positioned opposite and extending away from the four-cornered folds and the end panel sections. Each of the elongated corner pipes has an upper end with an elbow joint attached thereto. A first horizontal pipe is removably secured between the elbow joints forming an arch structure. Equally spaced from the elbow joints are a pair of tee joints disposed on the first horizontal pipe to be discussed in greater detail later. The other end of the corner pipes have base plates removably secured thereto. These base plates have a plurality of fastening holes that receive a fastening bolt or member to secure the corner pipes to the aforementioned ground surface, preferably a concrete surface. Note that other types of ground surfaces could be utilized.
Additionally, the elongated corner pipes have an anchor element with an extension member with a fastening hole therein. The corner pipes are positioned at an inner corner portion of the frame structure and outward from the four-cornered folds. Also, the corner portions of the frame structure includes a clamp member with a fastening hole therein to align with fastening hole of the anchor element to receive a fastening member therein to secure the corner poles to and within the inner corner portions of the frame structure to stabilize the trampoline and cage ball structure. Note that the positioning of the corner pipes at a distance outward of the enclosed cage structure allows the selectively spaced springs to stretch the cage structure at the four-cornered folds to maintain the enclosed cage structure in an outward stretched manner to prevent the collapsing of the enclosed cage structure. At an intermediate location on each of the corner pipes an offset joint is removably attached thereto. This allows a second horizontal pipe to be attached between the corner pipes at one receiving end of the offset joints to further stabilize the arch structure.
According to another aspect of the present invention, a pair of intermediate elongated stabilizing pipes has the same dimensions as the above recited corner pipes. Each of the elongated intermediate pipes has an upper end with an elbow joint attached thereto. A third horizontal pipe is removably secured to the elbow joints forming an arch structure across the top and intermediate portions of the side wall panel sections. A pair of spaced apart three-way 45 degree joints having two open ends and an angled open end positioned at selected space locations on the third horizontal pipe for receiving the second horizontal pipe through the two open ends of the three-way 45 degree joints and a tee-joint disposed at an intermediate location on the third horizontal pipe between the pair of spaced apart three-way 45 degree joints. Also, the intermediate elongated pipes have a three-way 45 degree joint positioned below the elbow joints and a swivel joint positioned below the three-way 45 joint of the intermediate elongated pipes and in alignment with the removable offset joints on the corner pipes.
A fourth pair of horizontal pipes located on opposite sides of the side wall panel sections. One pair of the fourth horizontal pipes is located on opposite sides of the side wall panel sections with one end being connected to the other ends of the offset joints of the corner pipes and the other ends are connected to one end of the swivel joint on one side of the intermediate elongated pipes. The other pair of fourth horizontal pipes is located on opposite sides of the side panel sections with one end being connected to the other ends of the offset joints of the corner pipes and the other ends are connected to one end of the swivel joint on the other side of the intermediate elongated pipes. The selected and spaced distance of the intermediate elongated pipes from the trampoline frame and the position of the corner pipes within the corner sections of the frame structure causes the fourth pair of horizontal pipes to be oriented and extended at an angle away from the side wall panel sections about the swivel joints to achieve greater stability and balance of the trampoline and cage structure.
The other ends of the intermediate elongated pipes have base plates removably secured thereto. These base plates have a plurality of fastening holes that receive a fastening bolt or member to secure the intermediate elongated pipes to the aforementioned ground surface. The intermediate pipes extend outside of the trampoline frame structure at a spaced and selected distance there from. A plurality of selectively spaced springs having one end connected to the aforementioned intermediate reinforced seam and the other end is connected to one end of a plurality of aligned chain elements with the other end of the aligned chain elements being connected to a plurality of a selectively spaced extending clamping tabs that are removably secured to the pair of elongated intermediate pipes for stretching the side wall panel sections outward for maintaining the cage structure in a constant full-stretched condition. This alleviates the cage structure from collapsing inward.
A pair of reinforced stainless steel or fiberglass rods is inserted through spaced openings along the reinforced seams forming gaps between the rods and the seams for securing a regular 9 feet middle net across the enclosed 12′×6′×12′ trampoline and caged ball game structure for dividing it into two equally 6′×6′ sections. Note that the net can be adjustable to different heights or different height nets can be utilized, if desired. The net is tightened and secured by a plurality of Velcro fasteners disposed along and adjacent the opposite edges of the middle net. In order to tightened the middle net a first portion of the Velcro fastener is inserted in the gaps between rods and the reinforced seams. Then the first portion of the Velcro fastener is pulled around the rods to secure the first Velcro portion to a second Velcro portion for tightly securing the middle within the trampoline and caged ball game structure.
Furthermore, the spring ends connected to the reinforced seam can be connected directly in the plurality of reinforced spring holes or they can be directly connected to one end of an S-shaped hook or other types of mechanical fasteners with the other end of the S-shaped hook or other types of mechanical fasteners being directly connected to the reinforced spring holes.
A further aspect of the present invention includes a fifth pair of horizontal pipes disposed on opposite sides of the third horizontal pipe having a pair of ends. One end of the fifth pair of horizontal pipes are connected to the previously mentioned spaced apart tee joints on the first horizontal pipes and the other ends of the fifth pair of horizontal pipes are connected to opposite ends of a cross joint coupler that is in abutting engagement with the aforementioned three-way 45 degree joints disposed on the third horizontal pipe. A pair of tee joints is selectively positioned on the fifth pair of horizontal pipes and selectively spaced from and aligned with the tee joints on the first horizontal pipes. A sixth and separate horizontal pipe is disposed on opposite sides of the third horizontal pipe and perpendicular to the fifth horizontal pipes. Each sixth horizontal pipe has a pair of ends connected between the tee joints the fifth horizontal pipes.
The fifth and sixth horizontal pipes are selectively positioned and spaced directly above the top open end of the side wall panel sections and the end wall panel sections of the cage structure, respectively. Prior to connecting the fifth and sixth horizontal pipes display banners are slidably disposed on each fifth and sixth horizontal pipes. This selective positioning and spacing allow for the display banners to hang down just enough to be stitched to the top of the end wall panel sections and the side wall panel sections to permanently hold them in place. These display banners can be used for displaying the name of the trampoline and cage ball game device and other types of advertising, if desired. Note that a pair of display banners is positioned on opposite sides of the aforementioned cross joint couplers with a space being created by the width of the cross joint couplers adjacent the ends of each of the fifth horizontal pipes connected to the cross joint couplers.
Further, in regards to the intermediate elongated pipe, a brace support pipe is attached to the aforementioned three-way 45 degree joint located on the third horizontal pipe that abuts the cross joint coupler and the aforementioned three-way 45 degree joint disposed below the elbow joints at the top of the intermediate elongated pipes forming substantially a 45 degree triangle. Also, the brace support includes a removable three-way 45 degree joint that has a straight portion with a pair of open ends slidable along the brace support and an angular portion with an open end extending from the straight portion. This three-way 45 degree joint is selectively positioned between the three-way 45 degree joint on the third horizontal pipe that abuts the cross joint coupler and the three-way 45 degree joint disposed below the elbow joints at the top of the intermediate elongated pipes, but in closer proximity to the three-way 45 degree joint on the third horizontal pipe and the cross joint coupler. A first short pipe having a first end attached to an open end of the angular portion and the other end has an elbow joint attached thereto that receives one end of a second short pipe that substantially forms a 90 degree angle.

The other ends of the plurality of selectively spaced springs 20 are connected to a plurality of aligned and selectively spaced clamping tabs 35 that are removably secured to a pair of elongated corner pipes 25 positioned opposite and extending away from the four-cornered folds 12 and the end panel sections 13. The plurality of spaced springs 20 includes a first end 20a secured directly within securing holes 12a of the plurality of four-cornered folds 12 and a second end 20b secured within a securing holes 35b disposed within an end portion 35a of the plurality of clamping tabs 35 (See FIG. 6). Optionally, the first ends 20a can be connected to one end of an S-shaped hook member 53a, while the other end thereof is directly connected into the plurality of securing holes 12a of the four-corned folds 12 for a stronger and more reliable connection (See FIG. 7). Each of the elongated corner pipes 25 has an upper end with an elbow joint 39 attached thereto. A first horizontal pipe 27 is removably secured between the elbow joints forming an arch structure. Equally spaced from the elbow joints 39 are a pair of tee joints 38 disposed on the first horizontal pipe to be discussed in greater detail later. The other end of the corner pipes 25 are removably attached to base plates 46 within an extension portion 47 extending upward there from. Also, base plates 46 have a plurality of fastening holes 51 that receive a fastening bolt or member (not shown) to secure the corner pipes 25 to the aforementioned ground surface, preferably a concrete surface. Note that other types of ground surfaces could be utilized.
In addition, the elongated corner pipes 25 have an anchor element 50 (shown in greater detail in FIGS. 18 and 19) with an extension member 50a (shown in greater detail in FIGS. 18 and 19) with a fastening hole 50b (shown in greater detail in FIGS. 18 and 19) therein. The corner pipes 25 are positioned at an inner corner portion of the frame structure 15, 16 and outward from the four-cornered folds 12. Also, the corner portions of the frame structure 15, 16 includes a clamp member 70 (shown in greater detail in FIGS. 18 and 19) with a fastening hole (not shown) therein to align with fastening hole 50b (shown in greater detail in FIGS. 18 and 19) of the anchor element 50 (shown in greater detail in FIGS. 18 and 19) to receive a fastening member having a head portion 71 and a leg portion 72 (shown in greater detail in FIGS. 18 and 19) therein to secure the corner pipes to and within the inner corner portions of the frame structure 15, 16 to stabilize the trampoline and cage ball structure 10. Preferably, the leg portion can include threads thereon to receive a tightening nut (not shown). However, the head 71 and the leg portion 72 can be selected from other types of fastening devices that are well known in the art. Note that the positioning of the corner pipes 25 at a distance outward of the enclosed cage structure allows the selectively spaced springs 20 to stretch the cage structure 10 at the four-cornered folds 12 to maintain the enclosed cage structure 10 in an outward stretched manner to prevent the collapsing thereof. At an intermediate location on each of the corner pipes 25 an offset joint 36 is removably attached thereto. This allows a second horizontal pipe 34 to be attached between the corner pipes 25 at one receiving end of the offset joints 36 to further stabilize the arch structure.
Still referring to the present invention, a pair of intermediate elongated stabilizing pipes 24 has the same dimensions as the above recited corner pipes 25. Each of the elongated intermediate pipes 24 has an upper end with an elbow joint 39 attached thereto. A third horizontal pipe 26 is removably secured to the elbow joints 39 forming an arch structure across the top and intermediate portions of the side wall panel sections 11.

One pair of the fourth horizontal pipes 33 is located on opposite sides of the side wall panel sections 11 with one end being connected to the other ends of the horizontal pipes 33 of the offset joints 36 of the corner pipes 25 and the other ends are connected to one end 37a of the swivel joint 37 on one side of the intermediate elongated pipes 24. The other pair of fourth horizontal pipes 33 is located on opposite sides of the side panel sections 11 with one end being connected to the other ends of the offset joints 36 of the corner pipes 25 and the other ends of the horizontal pipes 33 are connected to the other end 37a of the swivel joint 37 on the other side of the intermediate elongated pipes 24. Note that FIGS. 9 and 10 illustrate the swivel joint within the afore-mentioned ends 37a. The selected and spaced distance of the intermediate elongated pipes 24 from the trampoline frame 15, 16 and the position of the corner pipes 25 within the corner sections of the frame structure 15, 16 causes the fourth pair of horizontal pipes 33 to be oriented and extended at an angle away from the side wall panel sections 11 about the swivel joints 37 to achieve greater stability and balance of the trampoline and cage structure 10.
In FIGS. 1-5, the other ends of the intermediate elongated pipes 24 are removably attached to base plates 46 within an extension portion 47 extending upward there from.
