DETAILED DESCRIPTION

This disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. Also, the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” “having,” “containing,” “involving,” and variations thereof herein, is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.

The present disclosure relates to pools, particularly small swimming pools. In some embodiments, the small swimming pools are in-ground swimming pools. The small swimming pools that are known in the art are typically in the range of six feet to ten feet wide and no more than 20 feet in length. The primary advantages of this style of pool is lower cost, ease and speed of installation. These pools are typically made of concrete, steel panels, or fiberglass and can be surfaced with several different materials. In some embodiments, each pool has a bottom wall and four side walls. This size of pool goes by several names, such as “cocktail pool,” “spool,” “plunge pool” “garden pool,” and other names.

A small swimming pool made of concrete has structural advantages over pools that are not made of concrete. However, typical concrete pool construction involves several time-consuming and costly steps. Some concrete pools are precast, monolithic pools that are built and poured offsite and then transported to the site and set using a crane or boom truck. However, most monolithic pools are installed using a crane, which is not suitable for installing a pool in some locations because of local buildings, terrain features, or other obstacles. Because of the weight of the monolithic pool, a sufficiently powerful crane must be used and at a significant cost.

In addition to enabling rigid manufacturing standards, the present disclosure provides a modular pool and a method for installing a modular pool that saves a considerable amount of time and labor relative to previously known methods of installing a pool.

In some embodiments, the modular pool of the present disclosure includes a plurality of concrete modules that are precast. In some embodiments, the precast modules of the modular pool are made in a factory setting to exacting manufacturing standards. The precast modules are then loaded on a flatbed truck, delivered to the installation site, and assembled piece by piece using a crane or boom truck.

In some embodiments, the two primary modules of the modular pool are a concrete base unit and a concrete riser unit. The base unit defines a bottom wall of the pool, and the riser unit defines at least one side wall of the pool. In some embodiments, at least one side wall defined by the riser unit is four side walls of the pool. By separating the modular pool into two modules instead of one monolithic pool, the modular pool can be loaded, transported, and installed on site without the use of a crane (unless there is not enough access for a boom truck) saving considerable time and money on installation.

In some embodiments, the precast modules include internal structures for the pool. For example, the internal structures can include one or more benches and/or one or more sets of step risers that are configured to be placed on the base of the pool. Once the riser unit is set on the base unit, the precast benches and steps are then set in place. These modules and method of installation saves considerable time, labor, and materials relative to the previously known method of building these interior features using cement blocks. These modules and method of installation enables the plunge pool to be more customizable than other similar pools.

In some embodiments, the precast modules also include precast concrete panels that attach to the exterior of the riser section of the pool when the pool is designed to be sitting above grade by 16″-18″. Stone veneer is applied to the panels in a factory setting and the panels are shipped to the job site with the pool and the other precast modules. The precast panels and pre-application of the stone veneer saves a considerable amount of time and labor versus the prior known method of doing the work in the field where it is subject to the uncertainty of the weather.

In some embodiments, the precast modules also include precast “vaults” that are used to house the mechanism for an automatic cover. These precast “vaults” are made in a factory setting to exacting standards and are shipped to the site with the pool and other precast modules. The “vault” is then lowered into place with a boom truck or crane and attached to the side of the riser wall.

Because the individual modules of the pool are much lower in weight than a monolithic pool for a given pool interior volume, the modular pool of the present disclosure enables significantly larger pools to be easily transported and installed without the use of a crane (unless the installation crew cannot access the site with the boom truck). As a result, modular pools of the present disclosure can be significantly larger than previously known monolithic precast concrete pools (9 feet×21 feet vs 7 feet×13 feet) and do not typically require the use of a specialized crane. For example, an embodiment of a modular pool of the present disclosure having an inner footprint of 9 feet by 21 feet (outer footprint of 10 feet by 22 feet) can be installed with a boom truck, and without use of a specialized crane. Also, the modular design of the step inserts, benches, wall panels, and automatic cover vaults save significant time, labor, and materials over the alternative which is to build them using concrete blocks and mortar on-site.

For purposes of illustration, and with reference to FIG. 2, embodiments of the present disclosure will now be described with reference to a modular pool, generally indicated at 20, which can be subsequently lined, such as with a vinyl liner, frost-proof tile, or plaster, and used to contain water in which humans can swim. The modular pool 20 can be placed at least partially in-ground at a site 22, such as a backyard of a residential property.

The modular pool 20 includes a base unit 24 and a riser unit 26 that is supported on the base unit 24. Together the base unit 24 and the riser unit 26 define an interior volume of the modular pool 20, which is configured to serve as a reservoir for containing water. Within the interior volume of the modular pool 20, a variety of modular internal structures can be placed on the base unit 24. In FIG. 2, the internal structures include a bench 28, a bottom step 30, and a top step 32 supported on the bench 28. Each of the internal structures can be either precast or formed at the site 22.

The modular pool 20 is installed at a site by placing the base unit 24 in a hole that is dug into an area of ground at the intended installation site 22. The base unit 24 sits on the ground surface at a bottom of the hole. Then the riser unit 26 is placed on top of the base unit 24. A seal is formed between the riser unit 26 and the base unit 24 so that the base unit 24 and the riser 26 unit together define the interior volume of the modular pool 20 with an open upper end. In some embodiments, the interior volume is in the shape of a rectangular void. Then a liner (not shown), such as a liner made of vinyl, tile, or plaster, can be placed within the interior volume of the pool so that the liner covers the surfaces of the base unit 24, the riser unit 26, and the internal structures that were placed within the interior volume of the pool.

FIGS. 3 and 4 show additional perspective views of the modular pool 20 at the site. In some embodiments, siding panels, such as wood siding panels 34 as shown in FIG. 5, are placed around a portion of an exterior surface of riser that extends above the ground. FIG. 5 also shows an upper edging (coping) structure 36 that is placed over an upper end of the riser to provide a desired aesthetic appearance of the fully assembled modular pool 20.

FIG. 6 illustrates another embodiment of a modular pool, generally indicated at 50, of the present disclosure that is flush with the ground surface at a site 52. The modular pool 50 includes a base unit 54 and a riser unit 56 that is supported on the base unit 54. Together the base unit 54 and the riser unit 56 form a structure that defines an interior volume that can serve as a reservoir for containing water. Within the interior volume of the modular pool 50, a variety of modular internal structures can be placed on an upper surface 58 of the base unit 54. For example, in FIG. 6, the modular internal structures include a bottom step 60, a bench 62 adjacent to the bottom step 60, and a top step 64. The bottom step 60 and the bench 62 are supported on the upper surface 58 of the base unit 54. The top step 64 is supported on the bench 62.

FIGS. 7-14 illustrate steps of a method of installing the modular pool 50 of FIG. 6. In FIG. 7, the base unit 54 is seated on a recessed surface dug into an area of ground at the installation site 52. The modular internal structures are then lowered onto the base unit. In FIG. 7, the bottom step 60, the bench 62, and the top step 64 are placed on the upper surface 58 of the base unit and can be moved into their final installed positions later. The bottom step 60 is secured to the base unit 54 by a joining material at first interface 51. The bench 62 is secured to the base unit 54 by a joining material at second interface 53. The top step 64 is secured to the bench 62 by a joining material at third interface 55. The joining material at the first interface, the second interface, and the third interface may be an adhesion material. In some embodiments, the adhesion material consists essentially of mortar. In some embodiments, the adhesion material is mortar.

The riser unit 56 is then lowered onto the base unit 54 by operating a crane to lift and the lower the riser unit 56. The riser unit 56 is secured to the base unit 54 by a joining material at fourth interface 57. The bottom step 60 is secured to the riser unit 56 by a joining material at fifth interface 59. The bench 62 is secured to the riser unit 56 by a joining material at sixth interface 61. The top step is secured to the riser unit 56 by a joining material at seventh interface 63. The joining material at the fourth interface, the fifth interface, the sixth interface, and the seventh interface may be an adhesion material. In some embodiments, the adhesion material consists essentially of mortar. In some embodiments, the adhesion material is mortar.

FIGS. 8 and 9 show the riser unit 56 in place on the base unit 54. In FIGS. 8 and 9, the bench unit 62 is repositioned by the crane and again lowered onto the base unit 54 so the bench unit 62 rests on the upper surface 58 of the base unit. In FIGS. 10-12, mortar is applied to the top step 64, and the top step 64 is moved into place on the bench 60. When the mortar dries, the mortar secures the top step 64 to the bench 62. In FIGS. 13 and 14, mortar is applied to the bottom step riser, and the bottom step 60 is moved into place on the upper surface of the base unit adjacent the bench. When the mortar dries, the mortar secures the bottom step 60 to the upper surface 58 of the base unit 54. In some embodiments, operators apply mortar to the precast bench 62, the top step 64, and the bottom step 60 and move them into place within the modular pool 50 within 15 minutes. The installation time is much shorter than for similarly sized prior art pools. The decreased installation time enables a significantly decreased labor cost associated with installation of the modular pool 50 relative to prior art pools.

Embodiments of modular pools of the present disclosure can be made with various dimensions. FIGS. 15A-15D are blueprints showing a top view, a side view, a front view, and a back view for a modular pool 100 having an internal recess that is 16 feet long by 9 feet wide. The modular pool 100 includes a base unit 102, a riser unit 104, a first bench 106, a bottom step 108, and a top step 110, and a second bench 112. The base unit 102, the riser unit 104, the first bench 106, the bottom step 108, the top step 110, and the second bench 112 are all delivered to an installation site as precast concrete components.

FIG. 16A-16E is another set of blueprints showing the components of the modular pool 100 of FIG. 15.

The base unit 102 is configured to support the riser unit 104. The base unit 102 includes a bottom wall 116 and a relatively short side wall 118 extending upwardly from a perimeter of the bottom wall 116. As shown in FIG. 16A-16E, the bottom wall 116 and the side wall 118 of the base unit 102 are made of precast concrete and include rebar to reinforce the concrete. The bottom wall 116 includes a lower surface 120 that is configured to sit on a ground surface, such as a recessed surface in the ground at an installation site. The bottom wall 116 includes an upper surface 122 that is configured to support internal modular units and/or a pool liner. For example, the pool liner can be secured to the upper surface 122 by an adhesive.

The side wall 118 is configured to facilitate alignment of the base unit 102 with the riser unit 104. As shown in FIG. 16F, an upper surface 124 of the side wall of the base unit includes a stepped surface 128 that is configured to engage and align with a corresponding recess on mating stepped surface on a lower end of the riser unit 104. As shown in FIG. 16F, the height of the stepped surface 128 is 0.75 inch.

The riser unit 104 is configured to be lowered onto the base unit 102 and secured in place with respect to the base unit 102 so that the base unit 102 and the riser unit 104 together define a reservoir for containing water for swimming. The riser unit 104 is made of precast concrete and includes rebar to reinforce the concrete. The riser unit 104 includes four side wall portions 130 that are connected at four corners. The four side wall portions 130 of the riser unit 104 extend from an upper end of the riser unit that defines an open upper end of the pool to a lower end of the riser unit that is configured to be seated on the base unit 102.

A stepped surface 132 of the riser unit 104 is configured to facilitate alignment of the riser unit 104 with respect to the base unit 102. As shown in FIG. 16F, the stepped surface 132 of the riser unit 104 includes a recess 134 that is configured to engage and align with the corresponding stepped surface 128 on the upper surface of the base unit. As shown in FIG. 16F, the depth of the recess 134 is 0.75 inch.

The riser unit 104 includes an external surface 142 that is configured to be placed within a hole in the ground and an internal 144 surface that faces the interior volume of the pool structure. The internal surface 144 is configured to engage and/or support the pool liner. For example, the pool liner can be secured to the internal surface 144 by an adhesive. The base unit 102 and the riser unit 104 can have dimensions other than those shown in FIGS. 16A-16F.

FIGS. 17-19 show a concrete preform, indicated generally at 152, that can be used for pouring concrete to form a riser unit according to the present disclosure. The preform 152 includes an outer portion 154 and an inner portion 156. In FIG. 17, rebar 158 is arranged around the inner portion 156 of the preform 152. In some embodiments, the rebar 158 is held in tension prior to pouring concrete into the preform 152. When the inner portion 156 of the preform 152 1 is moved into place around the rebar 158, concrete is poured into the interior space of the preform to cast the riser unit.

One or more blanks may be used to define one or more ports in the riser unit. Posts 160 extend from the outer portion 154 of the preform 152 towards the inner portion 156 of the preform 152. The posts 160 are blanks that are provided to define ports in the form of channels in the riser unit. The channels are useful as water inlets and/or water outlets. The channels can be connected to external piping that is in fluid communication with a water pump to move water through the channels. A protrusion 162 extends from the outer portion 154 of the preform 152 to define a skimmer port 164 in one of the walls of the riser unit.

FIG. 20 shows a perspective view of an embodiment of a modular pool, indicated generally at 170, including a base unit (not shown), a riser unit 174, precast exterior wall panels 176 secured to the riser unit 174 and an external skimmer panel 178 that is secured to the riser unit 174. In some embodiments, stone veneer is attached the precast exterior wall panels. The precast skimmer panel 178 is shown separately in FIG. 21 and can be secured to an external surface of the riser unit around a skimmer port defined in the riser unit 174. FIGS. 22A and 22B show exemplary dimensions for the skimmer panel 178.

The precast exterior wall panels 172 can be secured to the external surface of the riser unit 174 after the riser unit 174 is moved into place on the base unit in the recess in the ground at the installation site. The precast exterior wall panels 172 eliminate the need to “pad out” the exterior wall of the riser unit 174 at the installation site, which would be needed when the upper end of the modular pool extends above the ground by 16 inches to 18 inches. In some embodiments, stone veneer is applied to the panels offsite, further reducing the amount of work needed at the installation site. FIGS. 23A and 22B show exemplary dimensions for the precast exterior wall panel.

FIGS. 24-28 show exemplary embodiments of internal modular units that can be placed in within the interior volume defined by the base unit and the riser unit. The internal modular units are precast and can be arranged within the interior volume of the pool structure as desired by a user. The internal modular units can sit directly on the upper surface of the base unit and/or on top of other internal modular units. In some embodiments, the internal modular units can be secured to the upper surface of the base unit. For example, in some embodiments, the internal modular units are secured to the upper surface of the base unit by mortar.

In particular, FIG. 24 shows exemplary dimensions of the upper step 64 of FIG. 6. FIG. 25 shows exemplary dimensions of the bottom step 60 of FIG. 6. FIG. 26 shows a lower perspective view of the bench 62 of FIG. 6. The bench 62 includes spacer blocks 180 to provide structural support for a hollow body of the bench 62. One of the spacer blocks 180 is shown in FIG. 27. Exemplary dimensions of the bench 62 are shown in FIGS. 28A-28E.

One or more benches or other modular platforms can be positioned in the pool to achieve desired internal features in the pool. For example, the height of the bench can be selected to create a shallow area in the pool that can be used as a built in lounge area, an area for sunning, or an area for small children to play in shallow water.
