[0002] This application claims the benefit of the priority of U.S. Application No. 16 / 866,662, filed on May 5, 2020, which is incorporated herein by reference. Technical Field

[0003] The present invention generally relates to pool covers. Background Art

[0004] Pools are common features in residences, hotels, and other venues. However, they often occupy a large amount of space. When the area is used for activities or entertainment that do not involve swimming or pool use, the planning must take into account the space occupied by the pool. For some situations, the space loss caused by the pool may make the location or venue unsuitable for hosting activities. In addition, during construction and other times, it may be necessary to cover the pool and the opening to prevent people, tools, and debris from entering the pool.

[0005] To make the venue usable, some people may empty the pool so that a floor can be built on scaffolding or other supports from the bottom of the pool. This requires a large amount of time and equipment to drain the water and build the supporting floor. Then it takes a large amount of time to remove the floor and refill the pool. In addition, the scaffolding and other supports may damage the bottom surface or even the liner of the pool.

[0006] Some venues may invest in and maintain a permanent floor structure that can be spread over the top of the pool area as an alternative to having a floor built on scaffolding. Such a permanent retractable floor requires a large amount of space to accommodate the floor adjacent to the pool and the equipment that moves the floor surface. Without prior planning for the floor, a permanent retractable floor may not be an option without significant renovations to accommodate the floor features. In addition, these floor surfaces are usually at a higher level than the surrounding area, requiring people to step up and down to get on and off the floor surface.

[0007] Finally, U.S. Patent No. 10,167,647 teaches "Modular Structure for Extension Over a Pool", which uses a series of sections that can be attached to extend over the pool. These sections include longitudinal members and cross - members that form a framework that lies on top of the surface surrounding the pool and extends over the pool. Tiles or slats are placed on top of the framework to form a surface. Like the retractable floor, the surface of the modular cover is at a higher level than the surrounding area, requiring people to step up and down to get on and off the surface. Summary of the Invention

[0008] The present disclosure provides a pool cover system that can also be used as a floor. The pool cover system can be assembled across the pool without damaging the pool structure or requiring any recessed mounting features. The pool cover system can also support a floor surface that is flush or substantially flush with the surrounding structure of the pool. The pool cover system provides a temporary cover and floor that do not require adjacent space for storing the surface when not in use as a cover.

[0009] The cover system can be used for many purposes, such as a floor surface for entertainment, as a safety cover to prevent people from falling in when the pool is not in use, or for other purposes. For example, the pool cover system can be used to winterize the pool during the off-season to prevent debris from entering and can provide an insulating layer. As another example, the pool cover system can be used as a safety cover to prevent children or others from falling into the pool when it is not in use.

[0010] The pool cover system can be installed and removed efficiently and is much faster than a scaffolding system. The pool cover system can be installed without emptying the pool. In some embodiments, for installation, the pool can be partially drained to an amount sufficient to be below the bottom of the pool cover system. In most embodiments, the pool can be drained 18 inches or less to accommodate the swimming cover system. In some embodiments, the pool can be not drained at all.

[0011] Embodiments of the pool cover system can include a series of brackets that hang from the edge of the pool structure into the pool opening. The brackets have vertical struts that extend downward from a hanger lip at the edge of the pool structure. Horizontal supports extend from the vertical struts away from the pool wall toward the opposite side of the pool.

[0012] Embodiments of the brackets can have a first side frame and a second side frame that are spaced apart a sufficient distance to allow a crossbeam to slide between the side frames. In some embodiments, the side frames angle upward from the front of the horizontal support toward the vertical strut near or to the hanger lip to form a triangular or similar shape. In some embodiments, the side frames are solid throughout the shape. In other embodiments, the side frames are bars or rods that leave all or part of the shape open. In another embodiment, the side frames can have areas removed (such as through multiple holes in other solid shapes).

[0013] In some embodiments, the brackets are made of rigid metal (such as steel, iron, or other metals). Some embodiments of the brackets can be made of other materials having sufficient stiffness and strength to support the assembled floor structure and the people and items placed thereon. The brackets can be coated with another material to provide a protective pad, waterproofing, or other features.

[0014] In some embodiments, the brackets are designed to fit over a coping of a particular type of pool cover, such as a square coping, an ogee coping, a rolled coping, a slender linear coping, or other coping types. For example, the brackets may include longer suspension lips for an ogee coping. As another example, the brackets may include angled suspension lips with additional supports and flexible materials to engage a slender linear coping or a rolled coping.

[0015] In some embodiments, the brackets may be angled to allow the crossbeam to pass through the pool at an angled orientation. In other embodiments, the side frames, horizontal supports, and vertical struts may be rotatable relative to the suspension lips. For example, the vertical struts may be connected to a rod that is rotatably connected to the suspension lips.

[0016] Embodiments of the pool covering system may also include a crossbeam or joist that extends between two brackets on opposite sides of the pool. In some embodiments, the crossbeam is placed between the side frames and abuts the horizontal supports of each of the two brackets. In this orientation, the crossbeam may be higher in the vertical direction than their width (referring to the width aligned between the side frames on the brackets).

[0017] In some embodiments, a static crossbeam of a set length is used between opposite brackets. In other embodiments, the crossbeam may be extendable to accommodate a range of lengths. The extendable crossbeam may include one or more extendable portions. In one embodiment, the crossbeam includes a central frame with two adjustable ends that have supports extending within the central frame. In another embodiment, the crossbeam may include two frame portions that include two ends connected by a support core.

[0018] The extendable crossbeam may include locking features to maintain the correct dimensions in some embodiments. Measuring features may include markings on the crossbeam that allow a user to adjust the crossbeam length to a desired length using pre-marked measurements. Some embodiments include covers or spacers to fill the height of the crossbeam across the extended area.

[0019] In some embodiments, a cross member is placed on top of the crossbeam. The orientation of the cross member may be substantially perpendicular to the crossbeam to create a grid pattern above the pool surface. Embodiments of the crossbeam may include recesses that are designed to fit the cross member and form a substantially flat top surface between the crossbeam and the cross member.

[0020] The cross member and the crossbeam may be attached to each other using connectors such as screws, bolts, studs, clips, fittings, or other connecting components.

[0021] An embodiment of a pool cover system can include a set of subfloor panels placed above the cross-members. A floor surface can then be placed above the subfloor panels to form the final floor. In some embodiments, the subfloor panels can be omitted, and the floor can be placed on the cross-members.

[0022] In some embodiments, the brackets can include light or sound features. For example, the brackets can include switches to turn on lights when installing the cross-beams. In some embodiments, the brackets can include a pair of switches on opposite sides of the side frames. Each switch can be connected to a light (such as an LED), a speaker, or other output. When installing the cross-beams, the switches can be triggered to cause the output to indicate a correctly installed cross-beam.

[0023] In some embodiments, the switches can cause different outputs to indicate an incorrectly installed cross-beam. The cross-beams can be designed to correspond to the switches to confirm correct placement. For example, the cross-beams can include pits or indentations corresponding to the switches. When the cross-beams are correctly placed, the switches are depressed and then spring back into the indentations. If the switches are not aligned with the indentations, they will not spring back into the indentations, indicating incorrect alignment.

[0024] In some embodiments, the cross-beams or cross-members can include light, sound, or other features. These features can be powered or controlled by an internal power source, a control processor, and wireless communication. In other embodiments, power supply or control can be facilitated through connection to the brackets. For example, the brackets can include nodes raised on the horizontal supports, and the raised nodes are configured to fit into corresponding indentations in the cross-beams to form an electrical connection. The nodes and indentations can include a sealing ring or cover configured to form a waterproof seal when the cross-beams are accurately connected to the brackets. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] While the present invention may be embodied in many different forms, preferred embodiments of the invention will be described in detail herein, with the understanding that the present disclosure is to be considered an illustrative example of the principles of the invention and not an attempt to limit the broad aspects of the invention to the embodiments shown. It should be understood that the invention may be embodied in other specific forms without departing from the spirit or central characteristics thereof. Accordingly, the embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not limited to the details given herein.

[0040] Figure 1 A partial embodiment of a pool cover system is shown. The pool cover system includes a bracket 102 that is suspended from a pool structure 104 and holds a crossbeam 108 across the pool. In this embodiment, the crossbeam 108 is shown above the water and below the surface of the pool structure 104. The crossbeam 108 supports cross members 106 that are spaced apart on top of the crossbeam 108. Floor panels 110 are on top of the cross members 106. The floor panels 110 can be underlying floor support panels (such as plywood) or final floor surfaces (such as dance floor surfaces or panels).

[0041] A pool covering system can use multiple individual supports 102 and crossbeams 108 to cover pools of many sizes and shapes to construct a sturdy cover. At Figure 1 The support 102 shown on one side corresponds to the support 102 on the opposite side to form support for the crossbeam 108. Figure 1 The support 102 shown has a suspension lip 112, a side frame 114, and a horizontal support 116. The suspension lip 112 extends above the top surface of the pool structure 104. In this embodiment, the side frame 114 aligns the crossbeam 108 in a vertical position above the horizontal support 116. The suspension lip 112 and the horizontal support 116 provide structural support for the crossbeam 108 suspended from the pool structure 104.

[0042] Multiple crossbeams 108 can be spaced along the pool using pairs of corresponding supports 102. Then, multiple cross-members 106 can be spaced on top of each crossbeam 108 to form a grid pattern. The spacing of the crossbeams 108 and the cross-members 106 can vary to accommodate the size of the pool and the support requirements for the floor. Additionally, based on the size, aesthetic, and support requirements of the pool, the sizes and materials of the supports 102, crossbeams 108, and cross-members 106 can vary for different installations. The size, shape, and material of the floor panel 110 can also vary based on the size, aesthetic, and support requirements of the pool.

[0043] As an example, a pool covering system for a small pool can use supports 102 configured to hold a two-by-six board (such as crossbeam 108) in a vertical orientation - that is, with the six-inch side extending vertically and the two-inch side extending horizontally. The length of the board will extend across the pool between the supports 102. These crossbeams 108 can be placed every 18 inches to form a sturdy base. The cross-members 106 can be one-by-four boards, placed substantially perpendicular to the length of the crossbeam 108 and spaced every two inches. The cross-members 106 can be placed horizontally, that is, with the one-inch side extending vertically and the four-inch side extending horizontally. Those skilled in the art of construction will recognize that the dimensions of the boards can be different from their specified dimensions. For example, a piece of two-by-four lumber may actually be 1.5” by 3.5”. Finally, the floor panel 110 can be a wooden dance floor.

[0044] As another example, a pool cover system for a large pool can use brackets 102 configured to hold two-by-twelve-inch beams 108 in a vertical orientation. These beams 108 can be placed every 21 inches to form a sturdy base. Two-by-four-inch cross-members 106 can be placed substantially perpendicular to the length of the beams 108 and spaced every 30 inches. The cross-members 106 can be placed horizontally. The floor panels 110 can be a subfloor plywood placed over the cross-members 106. Then the floor surface can be placed on the floor panels 110.

[0045] In some embodiments, components can be attached to each other using connectors such as screws, bolts, studs, clamps, nails, adhesives, adapter fittings, or other connectors. In some cases, attaching the components can result in a sturdier floor and in some cases less movement. For example, connecting the cross-members 106 to the beams 108 will reduce the ability of any one beam 108 to bend or shift independently of the other beams 108 and cross-members 106. Additionally, connecting the floor panels 110 to the cross-members 106 will reduce the noise generated by any gaps or flexing between the floor panels 110 and the cross-members 106. In some embodiments, gaskets or washers can be included on or between the brackets 102, cross-members 106, beams 108, or floor panels 110 to reduce noise and movement of the components.

[0046] The components can be made of various materials or combinations to provide structural support. Additionally, in certain applications, the support materials can be selected based on their aesthetics.

[0047] One of ordinary skill in the art will recognize that the brackets 102 can be constructed of any material that provides sufficient strength and stiffness to hold the floor structure in place using the suspension lip 112 and the horizontal support 116. For example, the brackets 102 can be made of metal, polycarbonate, polyethylene (HDPE or LDPE) plastic, PVC (polyvinyl chloride), or other combinations such as plastic with an integrated metal. In some embodiments, the material can include a structural material such as metal and a cladding surrounding the structural material such as a rubber, polyurethane, or nylon cladding. The cladding can be designed to provide a protective cushion, make the brackets 102 waterproof, provide an aesthetic finish, or provide other benefits. The material can be corrosion-resistant or covered with a sealant or material to provide corrosion protection. For example, a metal bracket 102 can be covered with a rust-proof sealant.

[0048] The beams 108 can be of any material that provides sufficient strength and stiffness to hold the floor structure above it. For example, the beams 108 can be made of wood, metal, It is formed of plastic, polycarbonate, fiberglass-reinforced plastic wood, polyethylene (HDPE or LDPE) plastic, PVC (polyvinyl chloride), or a combination of materials. The material can be corrosion-resistant or corrosion-proof, or covered with a sealant or material to provide corrosion protection.

[0049] Similarly, the cross member 106 can be any material that provides sufficient strength and stiffness to transfer the support from the cross beam 108 to the floor panel 110. For example, the cross member 106 can be made of wood, metal, plastic, polycarbonate, fiberglass-reinforced plastic wood, polyethylene (HDPE or LDPE) plastic, PVC (polyvinyl chloride), or a combination of materials. The floor panel 110 can also be any material that provides sufficient strength and stiffness for the intended purpose of the floor, including wood, metal, plastic, polycarbonate, fiberglass-reinforced plastic wood, polyethylene (HDPE or LDPE) plastic, PVC (polyvinyl chloride), or a combination of materials. The material can be corrosion-resistant or corrosion-proof, or covered with a sealant or material to provide corrosion protection.

[0050] Figure 2A An embodiment of the bracket 102 is shown. The bracket 102 includes a suspension lip 112, a side frame 114, a horizontal support 116, feet 118, and a vertical strut 120. Figure 2B A side view showing the bracket 102 in place on the pool structure 104 is provided. This embodiment includes a protective pad 124 on the feet 118. The protective pad 124 can be any soft, malleable, or protective material (such as rubber, plastic, nylon, or other materials).

[0051] The suspension lip 112 of the bracket 102 extends above the coping 122 of the pool structure 104 to hang from the top surface of the pool structure 104 into the opening of the pool structure 104. When the bracket 102 is suspended from the pool structure 104, a gap can be formed between the rear of the vertical strut 120 and the side of the pool structure 104.

[0052] In this embodiment, the pad 124 on the feet 118 contacts the side of the pool structure 104 below the coping 122. The protective pad 124 protects the side of the pool structure 104 and maintains the gap between the vertical strut 120 and the side of the pool structure 104. In some embodiments, the protective pad 124 can be covered on the feet 118. Some embodiments can be suspended from the top of the pool structure 104, and the feet 118 or the protective pad 124 do not contact the side of the pool structure 104.

[0053] In this embodiment, the water level line is shown below the horizontal support 116. During installation, this may require draining the pool a minimal amount to lower the water level below the bottom surface of the support 102. For example, the water level can be drained one foot to accommodate the floor structure. This significantly reduces the amount of water removed, which is better for the environment and reduces the amount of time required to remove water for installing other systems such as scaffolding.

[0054] In some embodiments, the support 102 and the cross beam 108 can be partially submerged in the pool water rather than draining the pool completely. These components can be made of waterproof materials or covered with waterproof materials to allow them to be submerged.

[0055] The pool cover system is attached to the pool structure 104 without the need for any bolts, screws, or other connectors to the pool structure 104. The pool cover system is supported by a plurality of suspension lips 112 on the supports 102 that are distributed around the pool structure 104. Some embodiments of the pool cover system may not require any tools for installation. In other embodiments, tools such as sledgehammers, hammers, or screwdrivers can be used to attach the cross beam 108, the cross members 106, and the floor panel 110 to each other. Some embodiments can also connect the cross beam 108 to the support 102.

[0056] The pool cover system can be quickly installed by a small team of people, reducing the time and cost required to cover the pool using existing methods and protecting the pool from damage during the process. In addition, since the pool does not need to be completely drained for installation, time and scheduling are more efficient.

[0057] Before installation, the installer or equipment owner can collect pool size and feature information to select the appropriate components for installation. For example, the owner can provide a pool blueprint with dimensions and coping information. Based on this information, the installer can select supports 102 that fit the cap and cross beams 108 of accurate dimensions. The cross beam 108 can be a custom, solid beam or an adjustable beam that fits each span. Some pools will require various different sizes of cross beams 108 and supports 102. The components can be numbered or colored or use other coding to indicate where the components should be placed. Installation guides showing the coding pattern can also be provided to facilitate installation. Once the materials are selected and delivered, the installation process can begin.

[0058] When the installation process begins, the user can start the draining process using a pump or any other conventional device while starting to lay out the components from storage or delivery. For embodiments of the pool cover system with waterproof or water-resistant components, the draining step can be skipped, or the components can be placed during the draining process. During this setup phase, the user can adjust the length of any expandable cross beam to correspond to the appropriate span length for installation.

[0059] For installations that include drainage, the drainage process can be stopped when the water level is below the horizontal support of the bracket 102. This level can vary depending on the desired bracket size. For example, if an eight-inch bracket is used, the pool can be drained eight inches or less depending on the starting water level relative to the edge of the pool. As another example, a larger pool can use a 16-inch bracket and be drained 16 inches or less.

[0060] For some installations, two or more people place the corresponding brackets 102 across the pool from each other and then place the crossbeams 108 vertically in the brackets 102. The people continue the work of placing brackets 102 and crossbeams 108 along the pool. In most installations, the crossbeams 108 are placed substantially parallel, although some pools can use crossbeams at different angles to handle bends or turns in the pool. For systems that include installation warnings or output features, the installer can ensure that there are no incorrect installation warnings and that any necessary features are accurately connected and attached.

[0061] Once the brackets 102 and crossbeams 108 are in place, the installer can begin placing the cross-members 106. In some embodiments, the process includes laying the cross-members 106 over a series of crossbeams 108 and attaching the cross-members 106 to the crossbeams 108. This can include using connectors to attach the components. In some embodiments, the cross-members 106 are placed in notches in the crossbeams 108 to form a flat or near-flat top surface. In some embodiments, the cross-members 106 are staggered so that any space between the cross-members 106 does not align across the pool.

[0062] Once the cross-members 106 are in place, one or more floor panels 110 can be placed over the cross-members 106. In some embodiments, a liner or cushion can be placed between the floor panel 110 and the cross-members 106. The liner can be used to absorb movement, noise, or both.

[0063] In other embodiments, an underfloor can be placed before the final floor layer is placed on top. The liner can be part of the underfloor or be placed separately before or after the underfloor.

[0064] In some embodiments, the floor layer or underfloor layer can be attached to the cross-members or crossbeams using connectors such as nails, screws, clips, friction connectors, or other connectors.

[0065] When the floor covering needs to be removed, the process is reversed. The connectors and the corresponding floor layers, cross members 106, and beams 108 are removed in sequence. In some embodiments, the components can be directly placed in a storage container or structure for housing the components to simplify future installation. For example, a dedicated storage container can include marked compartments or shelves, and each floor panel 110, subfloor board, cross member 106, and beam 108 is placed in the compartment or shelf according to its position for installation. For example, the first beam 108 can be placed in compartment one, the second beam in compartment two, and so on. The brackets 102 can also have designated storage locations in the container. Once the pool covering system is accurately stored, the storage container can be moved to a remote or on-site location until the next use.

[0066] In some embodiments, the bracket 102 can include hinged or slidable horizontal supports, suspension lips 112, or other features that are designed to reduce storage space while still providing sufficient structural integrity during installation. Additionally, the brackets 102 can be designed to stack together to reduce space.

[0067] Figure 3 An embodiment of the bracket 202 in a proper position on the pool structure 204 is shown. The bracket 202 includes suspension lips 212, side frames 214, horizontal supports 216, feet 218, and vertical struts 220. This embodiment also includes a protective pad 224 on the feet 218.

[0068] The suspension lips 212 of the bracket 202 extend above the coping 222 of the pool structure 204. The coping 222 in this embodiment includes a curved nose that protrudes and extends forward. The suspension lips 212 in this embodiment include a second layer 208 and an extensible layer 210. The second layer 208 provides additional structural support from the vertical strut 220 near the distal end of the suspension lips 212. In some embodiments, the distal end of the suspension lips 212 can include a thicker or more rigid portion instead of the second layer 208.

[0069] The extensible layer 210 can provide a protective layer formed relative to the curved and forward nose of the coping 222. In some embodiments, the extensible layer 210 can be denser near the distal end of the suspension lips 212 below the second layer 208 and less dense above the nose of the coping 222 to further protect the nose portion. The extensible layer 210 can be rubber, silicone, nylon, plastic, polyurethane, or other materials or combinations of materials.

[0070] The suspension lip 212 is also shown to be longer than the existing suspension lip 112. This allows the distal end of the suspension lip 212 to apply pressure to the pool structure 204 rather than directly to the nose of the cover top 222. The suspension lip 212 in this embodiment also includes a downward angle toward the distal end to further direct the pressure toward the body of the pool structure 204 rather than the nose of the cover top 222.

[0071] The suspension lip 212 hangs above the cover top 222 of the pool structure 204 and extends into the opening of the pool structure 204. When the bracket 202 is suspended from the pool structure 204, a gap may be created between the rear of the vertical strut 220 and the side of the pool structure 204. In this example, due to the extended nose of the cover top 222, the gap between the vertical strut 220 and the side of the pool structure 204 is relatively large.

[0072] The side frame 214 in this embodiment includes a plurality of openings or holes 206. These holes 206 can reduce the weight of the bracket 202 without reducing the strength of the bracket 202. Additionally, the holes 206 can allow water to move around and through the side frame 214 in a submersible embodiment. The holes 206 can also allow a user to confirm whether the cross beam is accurately positioned within the bracket 202. Similar to other brackets, the side frames 214 are spaced apart to keep the cross beam aligned above the horizontal support 216. The space between the side frames 214 also ensures that the cross beam is accurately oriented within the bracket 202. For example, the spacing of the side frames 214 can ensure that the cross beam is vertically oriented as Figure 1 shown.

[0073] Figure 4 An embodiment of a bracket 302 in a proper position on a pool structure 304 is shown. The bracket 302 includes a suspension lip 312, a side frame 314, a horizontal support 316, feet 318, and a vertical strut 320. This embodiment also includes a protective pad 324 on the feet 318.

[0074] The suspension lip 312 of the bracket 302 extends above the cover top 322 of the pool structure 304. The cover top 322 in this embodiment includes a curved nose that extends forward, and the top surface of the pool structure 304 slopes slightly toward the nose of the cover top 322. In this embodiment, the bracket 302 includes a malleable layer 310 adjacent the vertical strut 320 below the suspension lip 312. The malleable layer 310 can provide a protective layer relative to the forward nose of the cover top 322. The malleable layer 310 can be rubber, silicone, nylon, plastic, polyurethane, or other materials or a combination of materials.

[0075] In this embodiment, the suspension lip 312 is longer than the suspension lip 112 and shorter than the suspension lip 212. The suspension lip 312 is configured to be of sufficient length to allow the suspension lip 312 to apply pressure to the pool structure 304 rather than directly to the nose of the cover top 322. The suspension lip 312 in this embodiment also includes a downward angle toward the distal end to correspond to the inclination of the pool structure 304 toward the nose of the cover top 322.

[0076] The suspension lip 312 hangs above the cover top 322 from the pool structure 304 and extends into the opening of the pool structure 304. When the bracket 302 is suspended from the pool structure 304, a gap may be created between the rear of the vertical strut 320 and the side of the pool structure 304. This gap accommodates the extended nose of the cover top 322.

[0077] The side frame 314 in this embodiment is a bar or rod that extends around the top of the vertical strut 320 to the edge of the horizontal support 316 away from the pool structure 304. These side frames 314 define an opening area 306 between the side frame 314 and the vertical strut 320, so that the weight of the bracket 302 can be reduced without reducing the strength of the bracket 302. In addition, the open area 306 can allow water to move around and through the side frame 314 in a submersion application. The opening area 306 can also allow a user to confirm that the cross beam is accurately located in the bracket 302. Similar to other brackets, the side frames 314 are spaced apart to keep the cross beam aligned above the horizontal support 316. The space between the side frames 314 also ensures that the cross beam is accurately oriented in the bracket 302. For example, the spacing of the side frames 314 can ensure that the cross beam is vertically oriented as Figure 1 shown.

[0078] Figure 5 Another embodiment of the bracket 402 is shown. The bracket 402 includes a suspension plate 404 that is connected to a suspension lip (not shown in this view). The suspension plate 404 extends downward relative to the horizontal support 412 to form a vertical strut 406.

[0079] The bracket 402 includes side frames 408 and 410. The side frame 408 includes a switch 414 that is connected to an output 422 by a wire 418. The side frame 410 includes a switch 416 that is connected to an output 424 by a wire 420. The outputs 422 and 424 can be visual, such as lights (LED, conventional, or other types), audio outputs (such as speakers), or other types of outputs. In some embodiments, the outputs 422 and 424 can be operably controlled by a mechanical connection or a wireless connection rather than the wires 418 and 420.

[0080] In some embodiments, when a dimensionally accurate crossbar is accurately placed in the bracket 402, switches 414 and 416 are depressed. When switches 414 and 416 are depressed, the corresponding outputs 422 and 424 are turned on or set to indicate an accurate connection. In some embodiments, outputs 422 and 424 may use one output (e.g., green or a ringtone) to indicate correct placement, or a second indication (e.g., red or a buzzer) to indicate incorrect placement.

[0081] As an example, if someone places a one-inch board in a bracket 402 that is set up for a two-inch board, switches 416 and 418 may not be depressed accurately, or one may be depressed while the other is not. The user can see that only one of outputs 422 and 424 shows an accurate indication or neither shows an accurate indication.

[0082] In some embodiments, the crossbar and bracket 402 may be configured to fit together. The crossbar may include a pair of pits corresponding to the spacing and placement of switches 414 and 416. When the crossbar is placed, the crossbar first causes switches 414 and 416 to be depressed and then extends partway into the corresponding pits. The bracket 402 can confirm that switches 414 and 416 were depressed before the partial extension. Once confirmed, outputs 422 and 424 can show a light to indicate accurate crossbar placement. Additionally, the structure of switches 414 and 416 can engage the pits in the crossbar to form a latch that holds the crossbar in place to prevent horizontal movement.

[0083] In some embodiments, the crossbar may include corresponding ports to form a connection to indicate accurate placement. For example, switches 414 and 416 may include contacts corresponding to metal plates on the crossbar. When the crossbar is accurately aligned, the metal plates complete the connection on switches 414 and 416 to power outputs 422 and 424. In some embodiments, other sensors may be used instead of switches 414 and 416.

[0084] In some embodiments, outputs 422 and 424 may be wirelessly connected to a fitness application or other electronic device to confirm accurate installation of the enclosure system. For example, when switches 414 and 416 are depressed, the bracket 402 can send a signal via low energy Bluetooth communication to a smartphone or tablet to indicate accurate installation.

[0085] Figure 6 A close-up perspective view of a bracket 502 hanging from a pool structure 504 having a crossbar 506 is shown. The bracket 502 includes a suspension lip 510 above the edge of the pool structure 504 and a horizontal support 512 that supports the crossbar 506.

[0086] In this embodiment, the bracket 502 includes a sensor 516 on the horizontal support member 512. The sensor 516 can be a pressure sensor, a temperature sensor, a motion sensor, or other types of sensors. As an example, the sensor 516 can be used to measure pressure during installation and monitor pressure during use. Multiple sensors 516 throughout the covering system can be used to confirm the accurate installation of the cross beam 506 and serve as the safe use of the floor system. In addition, the sensor 516 can monitor threshold conditions during the use of the floor system. For example, the sensor can operate with a monitoring application to ensure that no excessive weight is placed on the floor system.

[0087] In some embodiments, the sensor 516 can be part of a raised node or protrusion corresponding to a pit or indentation in the bottom of the cross beam 506. The cross beam 506 can be placed in the bracket 502 to fit above the protrusion, thereby restricting the horizontal movement of the cross beam 506.

[0088] In some embodiments, the sensor 516 can be a connector to form an attachment to the cross beam 506. In this embodiment, the sensor 516 can be a contact sensor to ensure an accurate connection between the cross beam 506 and the bracket 502. In addition, this connection can supply power to the cross beam 506. For example, a raised node on the horizontal support member 512 can be configured to fit into a corresponding indentation in the cross beam 506 to form an electrical connection. The node and the indentation can include a sealing ring or cover configured to form a waterproof seal when the cross beam is accurately connected to the bracket.

[0089] In this embodiment, the cross beam 506 includes an electrical connection to an output in the form of a wire 518. In this embodiment, the output is shown as an LED strip 520. In other embodiments, the output can be other lighting systems, audio systems, vibration systems, or other systems. These output systems can be used for additional aesthetic and entertainment purposes. In these embodiments, the floor panel for this design can be a clean or transparent material to allow the light from the LED strip 520 to be visible through the floor.

[0090] In other embodiments, these output features can be powered or controlled by an internal power source, a control processor, and wireless communication. In these embodiments, the sensor 516 may not form an electrical connection with the cross beam 506.

[0091] Figure 7 An embodiment is shown with a cross beam 600 having an adjustable length. The cross beam 600 includes a central frame 602, a first end 604, and a second end 606. The second end 606 includes a second extension 610 that fits within an opening 608 of the central frame 602. The first end 604 also includes a first extension 612 that fits within the opposite side of the opening 608 in the central frame 602.

[0092] In some embodiments, the opening 608 may extend the entire length of the central frame 602. In other embodiments, the opening 608 may only partially extend into each side of the central frame 602 to allow the extensions 610 and 612 to fit fully within the central frame 602. Additionally, the central frame 602 and the extensions 610 and 612 may have corresponding features (such as protrusions and channels) that prevent the removal of the extensions 610 and 612 from the central frame 602. The opening 608 and the extensions 610 and 612 are sized to fit closely together while allowing horizontal movement to adjust the length of the crossbeam 600. The tight fit significantly limits vertical movement and any bending between the central frame 602 and the ends 604 and 606.

[0093] In most embodiments, the crossbeam 600 is made of a rigid material and is configured to maintain structural integrity along the length of the crossbeam 600 regardless of its extended state. In some embodiments, a semi-rigid material may be used for the crossbeam 600 as long as it maintains structural integrity within allowable tolerances. In some embodiments, the crossbeam 600 may provide rigid or near-rigid vertical support even if the material is allowed to be flexible in a plane perpendicular to the length of the crossbeam 600. When installed, cross-members may be connected to the crossbeam 600 to minimize or eliminate vertical movement.

[0094] The crossbeam 600 may be formed of wood, metal, plastic, polycarbonate, fiberglass-reinforced plastic lumber, polyethylene (HDPE or LDPE) plastic, PVC (polyvinyl chloride), or a combination of materials. For example, the central frame 602 may be formed of metal, while the ends 604 and 606 are materials with embedded metal posts in the extensions 610 and 612.

[0095] Figure 8 An alternative extendable crossbeam 700 is shown. The crossbeam 700 includes a first end frame 702 and a second end frame 704 connected by a central joist 706. Each end frame 702 and 704 includes an opening 708 for the central joist 706 to fit therein.

[0096] The crossbeam 700 can be extended from a minimum length to a fully extended length, with its end frames 702 and 704 contacting and completely surrounding the central joist 706. At the fully extended length, the end frames 702 and 704 are separated and only overlap the central joist 706 by a sufficient amount to minimize or prevent excessive bending of the crossbeam 700. The required degree of overlap can depend on the materials used in the end frames 702 and 704 and the central joist 706. For example, for strong and rigid metals, a minimal amount of overlap may be sufficient, while for polycarbonate, a large amount of overlap may be required.

[0097] In addition, this embodiment includes a spacer 710 that is designed to fit above the top of the central joist 706 and is located in the gap between the first end frame 702 and the second end frame 704. The height of the spacer 710 is designed to make the level (height) of the top surface of the crossbeam 700 across the gap match the level of the top surfaces of the end frames 702 and 704. The pool cover system can include a plurality of optional spacers 710 of different lengths to correspond to the potential gaps formed in the extensible crossbeam 700.

[0098] The spacer 710 is connected to an opening 712 in the central joist 706 using a connector 714. In some embodiments, the connector 714 can be pegs that fit into the opening 712. In some embodiments, the connector 714 can be built into the spacer 710. In other embodiments, the spacer 710 is designed to engage the connector 714 with both the spacer 710 and the opening 712. The connector 714 can be any type of connector capable of holding the spacer 710 to the central joist 706, such as screws, bolts, nails, locking pins, friction connectors, and other connectors. The opening 712 can correspond to the connector 714. For example, the opening 712 can be a pilot hole relative to a lead screw. As another example, the opening 712 can be a channeled opening that corresponds to a locking peg with one or more protrusions for locking into a groove in the opening.

[0099] During installation, the crossbeam 700 can be extended by moving the first end frame 702 and / or the second end frame 704 away to fit between two brackets on opposite sides of the opening. The spacer 710 can be attached to the top surface of the center joist 706 using the connector 714 and the corresponding opening 712 to secure the spacer 710. The spacer 710 also keeps the end frames 702 and 704 separated during installation until the accurate length of the crossbeam 700.

[0100] Figure 9An adjustable alternative crossbeam 800 is shown. The crossbeam 800 includes a first end frame 802 and a second end frame 804 connected by a central joist 806. Each end frame 802 and 804 includes an opening 808 for the central joist 806 to fit into and slide therein. As shown by the dashed lines, the opening 808 extends into each end frame 802 and 804 to allow movement of the central joist 806.

[0101] The crossbeam 800 can be extended from a minimum length to a fully extended length, where the end frames 802 and 804 contact and completely surround the central joist 806. At this fully extended length, the end frames 802 and 804 are separated and only overlap the central joist 806 by an amount sufficient to minimize or prevent excessive bending of the crossbeam 800. The required degree of overlap can depend on the materials used in the end frames 802 and 804 and the central joist 806. For example, for strong and rigid metals, a minimal amount of overlap may be sufficient, while for polycarbonate, more overlap may be required.

[0102] The central joist 806 is shown as being off - center, with the overlapping portion within the end frame 804 being less than the overlapping portion within the end frame 802. Additionally, the lengths of the end frames 802 and 804 can vary, as indicated by the break spacing in the crossbeam 800. Although this variability in overlap is shown in the end frames 802 and 804, the length of the central joist 806 can also vary. The lengths of the central joist 806 and the end frames 802 and 804 can vary together.

[0103] Furthermore, this embodiment includes a spacer 810 designed to fit over the top of the central joist 806 and located in the gap between the first end frame 802 and the second end frame 804. In this embodiment, the spacer 810 includes a top 812 and two sides, defining an opening 814 to fit over the central joist 806. The thickness of the top 812 of the spacer 810 is designed to make the horizontal level of the top surface of the crossbeam 800 across the gap match the horizontal level of the top surfaces of the end frames 802 and 804. Additionally, the sides of the spacer 810 can correspond to the thicknesses of the sides of the end frames 802 and 804 to create a consistent appearance for the entire crossbeam 800. The pool cover system can include a plurality of optional spacers 810 of different lengths to correspond to the potential gaps formed in the extendable crossbeam 800. In some embodiments, some spacers 810 can allow variable lengths to fit various gaps and accommodate the sizes and shapes of various pools.

[0104] The spacer 810 can prevent the end frames 802 and 804 from sliding inward and shortening the cross beam 800 from its desired length. In some embodiments, the spacer 810 can include connectors or other features to connect the central joist 806 to the end frames 802 and 804. In this embodiment, the spacer 810 can also prevent the end frames 802 and 804 from separating and extend the cross beam 800.

[0105] Figure 10 One end of an adjustable cross beam 900 is shown. The cross beam 900 includes a central frame 902 and a first end 904, which includes a first extension 906. The cross beam 900 can include a second end having a second extension at the opposite end (not shown). The central frame 902 includes an opening 908 in which the first extension 906 slides to allow adjustment of the length of the cross beam 900.

[0106] In this embodiment, the first extension 906 includes a series of openings 910 that are spaced along a portion of the length of the first extension 906. Connectors (such as studs 912 and 914) can be configured to fit within the openings 910. In other embodiments, the connector can be any type of connector that can limit the lateral movement of the first extension 906 relative to the central frame 902, including screws, bolts, clips, friction fittings, locking fittings, or other connectors.

[0107] The central frame 902 includes a channel 916 that is aligned with the openings 910. Different openings 910 can be obtained based on the extended length of the first end 904. When the first end 904 is in place, the first stud 912 and the second stud 914 are placed in the openings 910. The first stud 912 can be placed in the opening 910 in the channel 916 closest to the first end 904, and the second stud 914 can be placed in the opening 910 in the channel 916 farthest from the first end 904. Then, these studs 912 and 914 limit the lateral movement of the first end 904 relative to the central frame 902, thereby maintaining the desired length of the cross beam 900.

[0108] In some embodiments, the openings 910 can be spaced a defined distance (such as one inch) to allow the user to use the openings for measurement to adjust the cross beam 900 to a specified length. In these embodiments, for ease of use, the openings can be marked with their distance adjustments. In other embodiments of the adjustable cross beam 900, the adjustment measurements can be placed on the surface of the extension that is separate from the openings 910.

[0109] In some embodiments, the first extension 906 can include permanent protrusions or studs located within the respective channels 916, designed to limit the overall adjustment ability of the cross beam 900. This option can be used to ensure that sufficient structural overlap is always maintained.

[0110] Figure 11 Shows a partial embodiment of a pool covering system. This embodiment includes a series of brackets 1002 suspended from a pool structure 1004. The brackets include suspension lips 1012, side frames 1014, horizontal supports (not shown), and other features described with other bracket embodiments. In this embodiment, the upper portion 1016 of the side frame 1014 is marked to indicate the position where the top surface level of the cross beam 1008 intersects the side frame 1014.

[0111] The bracket 1002 holds the cross beam 1008, which supports the cross member 1006. In this embodiment, the cross beam 1008 and the cross member 1006 are designed to jointly provide a flat or nearly flat top surface to support a floor or sub-floor layer. In this embodiment, the cross beam 1008 includes notches 1022 for the cross member 1006 to fit therein. The depth of each notch 1022 corresponds to the thickness of the cross member 1006 to form a flat top surface.

[0112] In this embodiment, each cross member 1006 includes a series of member openings 1020 spaced along the length of the cross member 1006. As shown in this figure, the member openings 1020 can be spaced a predetermined amount for each cross beam 1008. In other embodiments, a series of member openings 1020 can provide alternative spacing options to allow for varying cross beam 1008 spacing. In some embodiments, the member openings 1020 can be channels or a series of connected openings to allow for small variations in the cross beam 1008 spacing. The cross beam 1008 includes beam openings 1024 in the notches 1022, which correspond to the member openings 1020.

[0113] This embodiment includes connectors 1018 and 1026. For illustrative purposes, connector 1018 is shown above the member opening 1020, while connectors 1026 are shown in the member opening 1020 and the beam opening 1024. Connectors 1018 and 1026 can be any type of connector, including studs, screws, bolts, friction connectors, locking connectors, snap-fit connectors, nails, or any other connector capable of holding the cross member 1006 and the cross beam 1008 in place. As discussed above, the openings 1020 and 1024 can be designed to fit or guide the connectors 1018 and 1026 into the appropriate positions. In this embodiment, the connectors 1018 and 1026 are studs that prevent the cross member 1006 from moving in the lateral direction along the length of the cross member 1006. The notches 1022 prevent the cross member 1006 from moving back and forth (side-to-side movement) along the length of the cross beam 1008.

[0114] In some embodiments, studs 1018 and 1026 may be pre - connected or integrated into cross - member 1006 or beam 1008. The corresponding components have openings 1020 or 1024 for the studs 1018 or 1026 to fit therein.

[0115] In other embodiments, cross - member 1006 may include a series of cross - member notches corresponding to notch 102. In these embodiments, the combined depth of notch 1022 and the cross - member notches may result in a flat or nearly flat top surface of beam 1008 and cross - member 1006. The overlapping portion of the two sets of notches prevents lateral and back - and - forth movement of cross - member 1006. In these embodiments, connectors 1018 and 1026 may not be necessary or may be included in the system.

[0116] In the present embodiment, beam 1008 and cross - member 1006 form an interwoven grid with a flat or nearly flat top surface. The common flat surface increases the surface area of the top surface for supporting the floor or sub - floor material. This additional surface area can provide more structural support and allow for alternative floor options. For example, in the present embodiment, a thinner panel can be used directly on the top surface as a floor.

[0117] In some embodiments, the floor panel may include grooves that correspond to the top 1016 of side - frame 1014 that extends above the grid top surface of beam 1008 and cross - member 1006. These grooves can allow the floor surface to reach the edge of the pool structure 1004 and limit the movement of the panel. This can help the floor surface to be flush or nearly flush with the top surface of the pool structure 1004.

[0118] In other embodiments, the top 1016 of side - frame 1014 may be away from the bracket 1002, which causes the top of side - frame 1014 to be flush or below the top surface of the grid. In this embodiment, the floor can also extend to the edge of the pool structure 1004 and provide a top surface that is flush or nearly flush with the top surface of the pool structure 1004.

[0119] In other embodiments, additional flush spacers can provide an alternative for the sub - floor by forming a similarly flush top - surface grid. The flush spacers can fit on top of the beams, in the spaces between the beams.

[0120] In some embodiments, beam 1008 and cross - member 1006 may include output features, such as lights, speakers, or other outputs. Beam 1008 can receive electrical energy from one or more brackets 1002. Beam 1008 can transfer the electrical energy to cross - member 1006 through connectors 1018 and 1026.

[0121] Figure 12 A close-up perspective view of a bracket suspended from a pool structure 1104 having a crossbeam 1108 is shown. The bracket includes a suspension lip 1102, a suspension plate 1120, a side frame 1114, and a horizontal support 1116 above the edge of the pool structure 1104, and the horizontal support supports the crossbeam 1108. In this embodiment, the bracket is angled with respect to the suspension plate 1120 and the wall of the pool structure 1104. The angled bracket allows the pool cover structure to be installed in a pool with curved or angled features in the design.

[0122] In some embodiments, the width or depth of the suspension lip 1102 can be greater to increase the overlap with the top surface of the pool structure 1104. This may be more important for a curved pool structure 1104 because of the gaps created based on the shape of the suspension plate 1120. In some embodiments, the suspension plate 1120 can have a curved rear to correspond to the pool structure 1104 and minimize the distance between the rear of the side frame 1114 and the wall of the pool structure 1104. The angled bracket can also include feet behind the horizontal support 1116 that are angled to correspond to the suspension plate 1120 and the wall of the pool structure 1104.

[0123] In some embodiments, the angled bracket can be a solid or rigid structure with a set angle. In other embodiments, the angle of the bracket can be adjustable. For example, the bracket can include a vertical strut having a rotatable connection to the suspension plate 1120 that provides support for the horizontal support 1116 and the side frame 1114. The side frame 1114 and the horizontal support 1116 can rotate with the vertical strut. In other embodiments, the vertical support can be rigidly connected to the suspension plate 1120 and the side frame 1114, and the horizontal plate 1116 can have a rotatable connection to the vertical strut.

[0124] The rotatable connection can be formed using a hinge, a bearing-based fitting, a toothed structure, or other structural rotatable connections. The connection can be freely rotatable or allow locking or holding at specific positions of its orientation. As an example, the vertical strut can have a post with a rotatable connection to the suspension plate 1120. The post can have a portion with a toothed or polygonal shape corresponding to the portion connected to the suspension plate 1120. The vertical strut can be lifted and rotated to the appropriate position and lowered to engage the shaped portion to prevent further rotational movement of the angled bracket.

[0125] Some embodiments of the pool cover system may include a double beam bracket that has a wider space between the side frames to hold a wider beam or two beams that are close to each other. In some embodiments, the double beam bracket may include a central frame between the outer frames to allow the user to guide each of the two beams into a proper position. The double beam can be used in places where additional support is needed, such as below the location of known heavy items (e.g., the main tent post). Additionally, the double beam can be used for longer spans or angles that require an alternative support design. For example, an "L"-shaped pool can use a double beam to support additional brackets for the beams that cover the corners of the pool shape.

[0126] Some embodiments may include support brackets to facilitate the vertical support of the posts. The vertical support posts can be used to provide additional support features to help prevent any bending or flexing in the middle portion of the beam. The bracket may include an open tube through which the vertical post passes until it bears against the bottom of the pool. When it abuts against the bottom of the pool, a latch, cotter pin, bolt, or other connector can be used to secure the vertical support post in place. The vertical support post can be made of a waterproof or water-resistant material or have a cladding to protect the pool structure and the water while providing the safety of auxiliary vertical support to limit any undesirable bending of the beam.

[0127] In some embodiments, the pool cover system may include a vertical post support designed to hold the ends of two separate beams in the middle of the pool. The vertical post support may include a waterproof material or cladding on the post and the base support. The top of the vertical post support may include a U-shaped bracket that has a horizontal support and two side frames for holding the ends of the two beams. The vertical support may also include a latch or connection system to hold the ends in place. In some embodiments, the vertical post support can be designed to hold a pair of beams that are close to each other to provide a stronger support system. A series of adjustable vertical supports can be used to support multiple beams in series to span a longer extension and accommodate larger pools, such as competition pools.

[0128] In some embodiments, the pool cover system can be used to convert the pool space into an alternative use space. For example, the venue pool of a school, fitness club, or other sports or entertainment facility can be covered by the pool cover system to allow the space to be converted into an auditorium space or an event space. The pool cover system provides an approximately horizontal space across the pool and the pool structure. In some embodiments, the components of the pool cover system (such as the floor) can incorporate a design or color (such as school colors or logos) corresponding to the building or the use of the building.

[0129] Some embodiments can be designed to provide only partial coverage of a pool or other open span. For example, a pool cover system can extend one-third over the pool while leaving the remaining two-thirds open for use or aesthetics. In these embodiments, the supports and crossbeams can be placed along one-third of the pool. The cross-members and floor layers extend only to the final crossbeam or just beyond the final crossbeam to provide the appearance of hanging over the pool. In these embodiments, handrail supports can be attached to the ends of the cross-members, floor layers, or final crossbeam. As an example, the handrail support can be a "U" shaped bracket that fits over the crossbeam and includes post retainers on the outside of the crossbeam that have snap connections to prevent the posts from coming out without releasing the snap or latch.

[0130] Some embodiments can be designed to temporarily bridge a pool or opening. For example, two crossbeams with corresponding supports can be placed along the edges of the desired width of the bridge, and the planks of a flat bridge can be replaced with planks attached to the crossbeams in place of the cross-members to form a flat bridge. Separate cross-members or underlying floor members can be used to increase the support strength for thinner floor materials. Similar to the partial coverage, handrails can be attached to the bridge.

[0131] In some embodiments, arched crossbeams can be used to form an arch bridge spanning an opening. Only in some embodiments can the arched crossbeam arch across the top. In other embodiments, the crossbeam can include corresponding arcs on the bottom. The arcs and ends of the crossbeam are configured to direct forces onto horizontal supports on the hanging brackets.

[0132] Some embodiments can include an arched attachment configured to fit over a crossbeam with a flat top to form an arched surface. The arch can be attached to the crossbeam using any connector. For example, multiple bilateral studs can be placed in holes in the crossbeam, and the arch can have corresponding holes in the bottom to fit over the studs. As another example, the bottom of the arch can have a "U" shaped bracket that fits over the crossbeam.

[0133] Some embodiments can include vertical post supports, such as for handrail connections. These vertical posts can be used to support items other than handrails or in place of handrails. In some embodiments, the vertical posts can be designed to hold an umbrella or other sheltering or covering feature. For example, a bridge can use a series of vertical posts to support a cover made of fabric, such as canvas, netting, or other fabric materials. Some embodiments can have pergola features spanning a portion of the pool.

[0134] Some embodiments can include modular features to form many different looks and designs. For example, a bridge can include a handrail system with vertical posts that pass through the floor into the crossbeams of the underlying floor deck. These posts can hold the floor in place while also supporting the handrail system. The tops of these posts can include removable caps that allow additional posts to fit into the tops extending that height. To form a pergola cover, additional vertical posts can be added to some of the vertical posts to increase the height. A cover can be attached to these additional vertical posts to form a pergola. Additionally, the system can include decorative features such as flags, finishes, and other features that can be placed in the vertical posts.

[0135] The modular system can include replaceable flanges, plugs, and other features to provide various options for developing different structures and looks. The crossbeams can include vertical holes to accommodate corresponding dowels or posts. Some floor embodiments can include dowels on the bottom that fit into holes in the crossbeams. These dowels can be fixed to the bottom of the floor, or they can be adjustable. For example, the dowels can be able to slide to accommodate different crossbeam spacings. Other floor embodiments can have corresponding holes to align with the holes in the crossbeams. Other components such as plugs, posts, flanges, and other features can be used to hold the floor in place. For example, a user can use a plug to pass through the floor into the crossbeam to provide a flat or near-flat surface for the floor. As another example, a user can lock the floor in place and allow attachment of additional fittings by installing a flange through the floor that has a dowel base and an open top to accommodate other items and mounting the flange in a hole in the crossbeam. As another example, vertical posts can be directly installed into the holes in the crossbeam without using a flange.

[0136] The modular system can include multiple alternative decorative features that are designed to extend the floor vertically or at an angle. In some embodiments, the modular system can include a pair of vertical posts configured to hold an extendable or retractable awning. In other embodiments, the vertical posts can be used to hold movable items such as basketball hoops, volleyball nets, and other items. Other components can be used to provide raised surfaces for human use such as life chairs or pedestals.

[0137] Other modular elements can be used to provide shelter or a rain cover above the floor. As an example, a pair of flexible tubes can be designed to bend from one flange or vertical post to another flange or vertical post to form a pair of corresponding arches. A cover material can span a portion of the arched tubes to provide shelter. Additionally, certain materials can also provide a rain cover.

[0138] Although the system has been described in the context of covering a pool, the system and components can relate to other applications across an opening, such as construction or repair applications. For example, the system can be used to form a working floor surface over an open portion of a multi-story room to service ceiling fixtures.

[0139] In some embodiments, brackets can be pre-attached to the crossbeam, allowing the crossbeam and brackets to be placed in one step. In other embodiments, one or more bracket components can be integrated with the crossbeam. For example, suspension lips can be integrated into the ends of the crossbeam to allow the crossbeam to be suspended across the pool opening.

[0140] Accordingly, the invention is described and further described in the claims, and it is apparent that the invention can vary in many ways. These variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications which are obvious to those skilled in the art are intended to be included within the scope of the described device.
