This application claims the benefit of U.S. Provisional Application No. 61/933,560 filed Jan. 30, 2014, which is incorporated herein by reference in its entirety.
TECHNICAL FIELDThis patent application relates to a user supportable surface including forced air flow through a playing surface.
BACKGROUNDPeople have been playing games on ice outside for hundreds of years. The modem sport of ice hockey, for instance, has been played since the 19th century. Curling is even older in origin, having been played in some form since the 16th century. Part of the enjoyment of these games is that one can glide across the ice along with the pucks or stones used to play the games.
These games originally required cold climates with large natural sheets of ice, such as frozen lakes, ponds, and rivers to play. In the 19th century, individuals found ways to create artificial sheets of ice in rinks using either the natural cold or artificial means of freezing water into ice.
These artificial rinks are not without their issues, however. For instance, it is extremely expensive and resource intensive to maintain an ice rink outside in warm and hot climates, such as Florida, Arizona, or Southern California. This forces individuals to play games such as ice hockey and curling inside or to forgo them altogether.
During the 1980s, inline skates using wheels became commercially popular. These inline skates mimic the feel of ice skates and allow the wearer to roll across solid surfaces (such as concrete or wooden floors) in much the same way that an ice skater glides across ice using ice skates. Inline skates can be used in a wider variety of climates and locations, including outside on sidewalks, parking lots, and roads even during hot summers.
Inline skates are also used to play hockey on solid, non-frozen surfaces, such as outside on concrete or other paved surfaces or inside on prepared surfaces such as a basketball court. Regular, flat hockey pucks do not slide on such surfaces, so inline hockey is played with different pucks or balls in place of traditional ice hockey pucks. Rubber pucks quickly come to a stop due to the increased friction they experience on inline hockey surfaces and so they behave quite differently than pucks do on ice. While balls roll and suffer less deceleration from the increased friction, they also behave differently due to their shape. For instance, balls easily bounce in a way that pucks do not.
In addition, inline and ice skates are difficult for some individuals to use for a variety of reasons (coordination, age, disabilities, etc.). For these individuals, there is still a desire to experience and enjoy playing ice games, but without having to use skates. Therefore, there is a need by some individuals for a way to play a hockey-like game wearing shoes (or in wheelchairs) that is not filled by using rubber pucks or balls on a concrete or wooden floor.
There is a real and unfulfilled desire for a way to play games similar to those played on ice in conditions and circumstances where it is difficult or inconvenient to do so using an ice rink or skates.
SUMMARYIn at least some implementations, a user supportable surface, includes a floor having a playing surface and a plurality of openings through the playing surface of the floor and a support on which the floor is supported above the ground to define at least part of an air chamber in communication with the openings. The support and floor arranged to support one or more people on the floor. Air flow may be directed or provided through the openings to provide a flow of air at the playing surface.
A system may include a surface or floor, an air chamber and a blower. The floor may have a plurality of openings and be adapted to support the weight of more than one person moving around on the floor. The air chamber is in communication with the openings, and the blower is communicated with the air chamber to force air through the air chamber and openings. In this way, a user supportable floor is provided with forced air flow along at least part of a playing surface of the floor.
A surface or floor may include a series of openings through which pressurized air is forced, thereby creating a cushion of air that substantially reduces the friction between the surface of the floor and items on the floor, such as pucks or stones. Pucks or stones can glide across this surface in much the same way that a hockey puck or curling stone glides across ice. Because the flooring is not made of ice, it can be used in a variety of different climates and temperatures without concern that the ice will melt and can be used with inline skates or shoes, instead of ice skates.
The floor can be made in modular sections, each with many openings. Each floor section can be assembled in a variety of shapes and sizes, from a small backyard rink for children to play on (e.g. 40 feet×24 feet), to a curling sheet (e.g. 150 feet×16 feet), or to a full-sized hockey rink (e.g., 200 feet×100 feet). The floor can easily be scaled or built to meet any need or desire.
The following detailed description of preferred embodiments and best mode will be set forth with reference to the accompanying drawings, in which:
Referring in more detail to the drawings,
In one embodiment, the floor 10 is part of a system 12 that includes the floor 10, a support 14 that defines at least part of an air chamber 16 beneath the floor 10 and one or more blowers 18 that move air through the air chamber 16 and through the floor 10. The floor may be created in modular sections 12 that can be assembled into different sized rinks or surfaces while allowing for disassembly and facilitating transportation. While this modularity is useful from a commercial, flexibility, and ease-of-use standpoint, the system 12 and floor 10 are not limited to modular embodiments. A single, permanent floor can be created and it may be formed from sections or materials of any desired size.
The floor 10 can be made from variety of rigid materials included natural and synthetic materials or combinations thereof, such as wood, metal, plastic or composite materials. One example is 0.75 inch thick polycarbonate sheets. Other materials and thicknesses can be used. For example, 0.5-0.75 inch HDPE or polypropylene sheets or tiles might be used for the playing surface in lieu of polycarbonate. Typical roller or inline hockey playing surfaces, like sport court tiles and the like, may also be used after modification to permit airflow therethrough as taught in this patent application.
The floor 10 includes a plurality of openings 20. The openings 20 have an outlet 22 at an outer or playing surface 24 of the floor. Air flows through the outlets 22 at an angle to the playing surface 24 of the floor 10 and in at least some implementations, that angle is about 90 degrees. The openings 20 may be of any shape and size to provide a desired airflow at the floor playing surface 24. For example, without limitation, the openings 20 in at least some embodiments may be generally straight bores formed through the thickness of the floor, e.g. through the panels or pieces defining the floor 10. Another representative example is shown in
The size of the outlets 22 and the spacing thereof may be varied as desired.
To facilitate airflow through the outlets 22 and to facilitate leveling the floor 10, the floor 10 may be positioned on the support structure 14 so that the floor is raised off of a subfloor 30 to create an air chamber 16 below the floor 10, as shown in
The floor 10 can be supported by a series of vertical supports 32 between the subfloor 30 and floor 10 that allow air to pass around and circulate between the supports 32 but are strong enough to support the weight and stresses of active individuals standing, running, jumping, and falling on the floor 10. For example, the floor 10 can be buttressed by one or more supports 32 extending between the subfloor 30 and floor 10 spaced at any desired interval. The supports may be wood, metal or plastic walls, tubes or other members and they may be spaced apart as desired, such as one to four inches in both horizontal directions in the case of relatively small tubes or rods (e.g. about one inch in diameter). The lengths of these supports 32 can be made to be adjustable to allow for leveling of the floor 10 off of or relative to the subfloor 30, which could be important if the floor is placed on uneven land. Or, the subfloor 30 or supports 32 may include adjustment features 34, such as adjustable feet to permit leveling and height adjustment of the floor 10. The adjustment features 34 may be of any type or arrangement to permit the height or incline of any part of the floor to be adjusted. Different spacing, heights, and support structures/materials could also be used.
The air that flows through the openings 20 in the floor 10 may be moved by one or more blowers 18 connected to air chamber 16 (
In an alternative embodiment, the air chamber 16 can be sectioned off into sub air chambers, and the sub air chambers may be at least partially isolated from one another. Each blower 18 (or a subset of all the blowers 18) could then push air through just one or more sub air chambers, instead of pushing air throughout a large air chamber 16 for the entire floor 10. For example, the air chamber 16 could be split into four sub air chambers, each with a single blower 18. Or, the air chamber 16 could be sectioned into two halves, with each half being fed air by two blowers 18 (for a total of four blowers 18 for the entire rink). The numbers of sub air chambers and blowers 18 connected to each sub air chamber can vary, depending on the needs of the user and the design considerations.
One example of a modular floor system 12 is shown in
The floor module 40 may also include one or more blowers 60 that may be carried by the base 44. In the example shown, one blower 60 is used and the remaining description thereof will refer to a single blower, though multiple blowers may be used if desired. In the example shown, the base 44 includes an interior wall that defines at least part of the subfloor 48 and the blower 60 is carried by the interior wall. An air chamber 62 is defined between the subfloor 48, sidewalls 46 and the floor section 42, and the air chamber 62 may be sealed, or mostly so, so that air flows into the air chamber 62 through the blower 60 and out of the air chamber 62 through the openings 20 in the floor section 42. The blower 60 draws air in from outside the air chamber 62 (e.g. through the intake air openings 52 and the space between the subfloor 48 and the ground) and forces that air into the air chamber 62 whereupon air flows under pressure through the openings 20 in the floor section 42. In at least some implementations, a separate blower 60 is provided for each floor module 40. The blower 60 may be coupled together by suitable electrical supply 66 and control, to facilitate powering and controlling the multiple blowers 60 that may be used in a floor system that includes multiple floor modules 40. Alternatively, the air chambers 62 of multiple floor modules 40 may be communicated with one another by suitable passages, conduits or openings in adjacent bases 44, for example. In this way, one fan or blower 60 may provide air to the air chambers 62 of multiple floor modules 40.
While the support members 56 are shown as passing through the subfloor 48 to the ground, separate support members 56 may be provided between the subfloor 48 and the floor section 42 and between the subfloor 48 and the ground to limit openings or penetrations through the subfloor 48. This may simplify leveling the floor module 40, such as with adjustment features (diagrammatically shown at 34) between the base 44 and the ground (e.g. shims or adjustable feet which may be threaded into the base 44, for example). The subfloor 48 and floor section 42 may define a separate module from a support or stand disposed between this separate module and the ground, if desired. In this way, the modules may be used with different stands to provide different heights, strengths or for any other reason. This in essence takes the module 40 from a one-piece unit into two or more pieces.
A plurality of modules 40 may be positioned side-by-side to form a larger, continuous floor 10 of any desired size and shape. The modules could be formed into a rink 11. The modules 40 may be connected together in any suitable manner, such as with brackets, fasteners, tongue and groove or other interlocking connection, adhesives, cables, ropes, bands, all of which are a few of the many possibilities. The connection could be made at the floor sections 42 or the bases 44 or at any stands, if provided. The modules may be of any desired size, providing any desired surface area floor sections 42 at any desired height. In one example, the floor sections are 3 feet by 3 feet square which makes them relatively easy to handle, assemble and transport.
The PuckWhile the floor systems 12 described above create a flow of air that is amenable to allowing objects to float or glide across the floor 10 or floor section 42 similar to the way that they might across a smooth surface of ice, not all objects will behave in this manner. If the object has a non-optimal weight or design, it will either remain stuck to the floor 10 as if there was no air flowing through the openings 20 or fly away due to the air blowing through the openings 20. Thus, the objects should fit within a range of weight, density, and shape to maximize the desired gliding effect and meet other objectives of the game or activity being played.
For a puck 68 similar in size and shape of an ice hockey puck (three inches in diameter and one inch thick), it has been determined that the circular faces on both sides of the puck should be hollowed out in order to achieve the proper weight and to create a recess or cavity 70 for the air that allows the puck to ride on a cushion of air in this pocket (as shown in
The puck 68 shown in
In addition to pucks, other objects could be formed for use on these surfaces, such as a stone, similar to that used in curling. The precise dimensions and materials could be optimized so that the stone mimics the way a curling stone acts on a smooth surface of ice. The term “float” is sometimes used in this description and it should be understood that this word may include situations where all of the puck is spaced from the floor surface, only some of the puck is spaced from the floor surface (e.g. some of the puck engages the floor), and none of the puck adjacent to the floor is spaced from the floor surface, but the effective weight of the puck is reduced or offset at least partially by the airflow acting on the puck which then reduces the frictional engagement of the puck with the floor. To further reduce friction between the floor and the puck, one or both of the floor and the puck may be formed from or coated with low friction materials.
Arena-Sized EmbodimentIn one exemplary embodiment of the invention, the modular floor pieces are assembled into an 80 feet×180 feet rink 11 with curved corners, similar in size to a standard ice hockey rink (
The floor is made from one or more panels or pieces of material such as (by way of one non-limiting example) 0.75 inch thick polycarbonate sheets with 0.125 inch diameter holes drilled approximately 1.0 inch on center from one another in a grid-like pattern, as shown in
Each section is supported from below by a series of lightweight, stackable, bases. The bases may be enclosed boxes or skeleton like structures that hold the floor sections up (and, therefore, the entire surface) and a series of support members (such as 1.5 foot long plastic or metal rigid tubes—rubber tips may be used for sound/vibration damping) may be provided for added support for each floor section. Each support member may be secured to the underside of each floor section 42 via countersunk bolts or other types of connectors. The bases may be the same size as the floor sections or they may be divided into 2 feet×2 feet (or other size) modular sections for ease of storage and shipping, if desired.
The bases, in turn, may rest on the ground or a modular support system or stands. In one implementation, the top of the floor is approximately 2.67 feet above the ground, although other heights are possible and can be implemented. In the example where the base includes a skeleton structure, panels may be provided to enclose the bases at the periphery of the rink 11 to enclose the air chamber or air chambers beneath the floor 10 and inhibit or prevent air from leaking out of the air chambers at the periphery of the rink 11.
The shape of the floor can be made in varying form factors. In one embodiment (as shown in
As shown in
As shown in
The pressurized air may be created by one or more blowers 18. In at least some forms, the blowers 18 may be capable of moving 18,000 cubic feet per minute of air through each blower. For example, 20 seven-horsepower blowers 18 surrounding the rink can be used. Alternatively, 10 fifteen-horsepower blowers 18 that move more air could be used. By positioning the blowers 18 uniformly around the rink, the blowers 18 will create a more uniform flow of air through the openings in the floor in order to give a more consistent air cushion across the entire floor surface. The blowers 18 may be located on the outside of the rink so that they can draw air from outside the rink and blow it into the air chamber(s) beneath the floor. Alternative numbers of blowers 18, strength of blowers 18, and positions could be used.
Optionally, artificial lighting can be placed on poles around and above the rink so that people can see and play on the surface outside when it is dark. In addition, the floor can be transparent, semi-transparent, or translucent. This light permeability allows lights 100 to be placed beneath or in the floor 10 to provide light that will shine up and through the floor, and, therefore, be visible to players and spectators watching from above. For example, these lights 100 could be LED, incandescent, or fluorescent lights, among others, and configured individually or collectively in ropes or connected sections (see, e.g.,
Alternatively, or in addition, these types of lights can be positioned in an arrayed pattern to make a television/video screen in or below the floor that would allow the operator to display a variety of static or dynamic images and text on the floor 10 itself (e.g., like an embedded Jumbotron or other arena large-screen display). For instance, the floor 10 could display the names or logos of sponsors, advertisers, the teams, the names of the players next to each player, when a goal was scored, who a penalty was called on, the time remaining in the game or a penalty, or replay a scene from the game, among many other things.
These lighting systems can be hardwired to be switched on and off manually (e.g., to turn on background illumination of the entire floor or to light up the specific lines or sections on the rink) or can be automatically controlled via a computer or microprocessor to dynamically change the lighting or display more complex effects in the same manner in which screen and displays at traditional arenas are controlled.
Backyard-Sized EmbodimentWhile large-scale rinks may be provided, the floor system 12 can also be used to make smaller rinks that could be placed in a backyard, park, or other smaller area. In one embodiment, the floor piece sections are assembled to form, for example, a flat 24 feet×40 feet rink with curved corners. The flooring surface may be entirely flat, if desired, unlike the banked example described above (although contours could be built into the rink if desired). The rink may be surrounded by 2 feet high wall on the sides and a 3.5 feet high wall around the ends of the rink that are finished with HDPE.
The floor or flooring sections may be comprised of 0.5 inch thick HDPE panels with 0.125 inch diameter holes located approximately one inch apart in both horizontal directions (non-cylindrical holes could also be used). The playing surface may be supported by 0.5 inch diameter, 6 inch long PVC pipe with a cap on the top and bottom for attachment to the base sheet. All vertical supports are placed on a 6 inch on center grid, in this example. A 7-horsepower blower 18 is located at each end of the rink in order to provide pressurized air below the floor that is forced through the holes in the floor. These blowers 18 may provide 18,000 cubic feet per minute of air flow can be used, for example. Alternatively, four smaller blowers 18 could be positioned at the corners of the rink. Different numbers of blowers 18, strength of blowers 18, and positions could be used.
Because the side walls are only 2 feet high in this example, entry gates might not be needed, although they could be placed on either (or both) sides to facilitate entry onto the surface, which would be helpful for children or those in wheelchairs that cannot easily scale the wall. All of the sizes are representative and are not intended to limit this disclosure.
Given the nature of the expected use and expected costs for this smaller rink, simpler lighting systems would likely be used (e.g., to identify certain areas of the rink or to provide additional ambient light). However, the more complex lighting systems described above could also be used with these smaller rinks, if desired.
Curling SheetWhile the embodiments described above are optimized for playing a form of hockey, the invention can be used to play other games, including a form of warm-weather curling.
In one embodiment, the floor piece sections are assembled to form a flat 16 feet×150 feet curling sheet. The flooring surface is entirely flat and is surrounded by a short wall (e.g. 1 feet high) around the ends of the sheet that are made of HDPE. This short wall section prevents the curling stone from leaving the surface during play.
The flooring sections are comprised of 0.5 inch thick HDPE panels with 0.125 inch diameter holes located approximately 1 inch apart in both horizontal directions. The flooring sections may be supported by a 7.25 inch high skeleton structure with supports every 6 inches that rest on a solid, flat subfloor. Multiple blowers 18 are located along the sides of the sheet in order to provide pressurized air below the floor that is forced through the holes in the floor. All of the sizes are representative and are not intended to limit this disclosure.
Given the nature of the expected use for this sheet, simpler lighting systems would likely be used (e.g., to identify certain areas of the sheet such as the centerline, hogline, free guard zone, and house, or to provide additional ambient light). However, the more complex lighting systems described earlier could also be used with these sheets, if desired, to show the score, players, or status of the game, among other things.
Because a curling stone is substantially larger than a hockey puck (approximately 13 inches in diameter and at least 4.5 inches high, versus the 3 inch diameter and 1 inch height for a hockey puck), the stone will have a different design that may mimic, at least in part, the way in which a curling stone moves across the ice.
MiscellaneousWhile a traditional hockey-type game can be played on the surface, other games, including modified hockey games, can also be played. For instance, a traditional hockey net/goal is approximately 4 feet high×6 feet wide×3 feet deep, and a single point is scored each time a puck crosses a goal line and enters into the goal area. A modified hockey net/goal that is approximately 4 feet high×7 feet wide×3 feet deep with two 7 inch wide×2 inch high×9 inch deep slots or sub goals in the bottom comers of the goal (one on each side) can be used. Instead of being worth one point, a puck that enters into these slots would be worth two or more points, for example, to the scoring team. A puck that enters into the remaining goal area would still be worth one point, or some other value as desired. Alternative sizes and scoring values could also be used, including sub goals in the upper comers or along the sides, top, or bottom of the goal.
While the forms of the invention herein disclosed constitute presently preferred embodiments, many others are possible. For example, while described with reference to hockey and curling, among other things, the floor system and teachings of this application can be used for other things, including games or activities not yet created. It is not intended herein to mention all the possible equivalent forms or ramifications of the invention. It is understood that the terms used herein are merely descriptive, rather than limiting, and that various changes may be made without departing from the spirit or scope of the invention. For example, relative location or orientation terms like upper, lower, side, top, bottom, left, right or the like are directed to the orientation of components in the drawings and are not intended to limit the invention unless expressly noted as such a limitation. It is contemplated that the components may be oriented and arranged in other ways.
