CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims the benefit of U.S. Nonprovisional

Application Serial No. 15/727,008 filed 06 October 2017; which claims the benefit of U.S. Provisional Application Serial No. 62/485,504 filed 14 April 2017; each of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

[0001] This disclosure relates to underfloor fluid conduction. BACKGROUND

[0002] In this disclosure, where a document, an act, and/or an item of knowledge is referred to and/or discussed, then such reference and/or discussion is not an admission that the document, the act, and/or the item of knowledge and/or any combination thereof was at a priority date, publicly available, known to a public, part of common general knowledge, and/or otherwise constitutes any prior art under any applicable statutory provisions; and/or is known to be relevant to any attempt to solve any problem with which this disclosure is concerned with. Further, nothing is disclaimed.

[0003] Underfloor hydronic tubing is commonly used to warm or cool various structures, such as residential homes. However, there are several problems with how the underfloor hydronic tubing is installed.

[0004] First, the underfloor hydronic tubing can be installed such that a thermal energy transfer between the underfloor hydronic tubing and a finished floor is not maximized. For example, if the underfloor hydronic tubing is installed such that a layer of thermally insulating material, such as a wood block, is positioned between the underfloor hydronic tubing and the finished floor, then such configuration reduces the thermal energy transfer between the underfloor hydronic tubing and the finished floor. As such, there is a desire to maximize the thermal energy transfer between the underfloor hydronic tubing and the finished floor.

[0005] Second, the underfloor hydronic tubing can be installed such that the underfloor hydronic tubing is exposed, which often results in puncturing of the underfloor hydronic tubing from a piece of debris, such as a nail or a shard of glass, at a work site. As such, there is a desire to minimize exposure of the underfloor hydronic tubing.

[0046] FIG. 1 shows an embodiment of a tube engagement unit according to this disclosure. A tube engagement unit 100 includes a plate 102 and a receptacle 104. The plate 102 and the receptacle 104 are unitary, such as monolithic. In some

embodiments, the plate 102 is assembled with the receptacle 104, such as via fastening, adhering, magnetizing, mating, or other means or methods. In some embodiments, the unit 100 is structured, manufactured, and used, as disclosed in US Patent 5,454,428, which is fully incorporated by reference herein.

[0047] The plate 102 is rectilinearly elongated, rectangularly shaped, and includes a thermally conductive material, such as metal, such as copper, iron, aluminum, or others, or an alloy, such as steel, brass, bronze, or others. Note that variations on such structure are possible, such as the plate 102 being non-rectilinearly elongated, such as sinusoidal, arcuate, pulsating, zigzag, or others, the plate 102 being non-rectangularly shaped, such as any polygonal shape, or any other variation in constituency, size, shape, or other characteristics.

[0048] In one or more embodiments, the plate 102 includes a plurality of bores 1 10 bored therethrough such that the receptacle 104 is positioned therebetween. The bores 1 10 are circular, but other shapes are possible, such as ovoid, elliptical, or others. The bores 1 10 are threaded, but may be smooth. The bores 1 10 are identical in shape and size, but can differ in shape, size, or any other characteristic, including positioning. In one or more embodiments, the plate 102 does not include bores 1 10.

[0049] The receptacle 104 is defined via a pair of legs 106 and includes a thermally conductive material, such as metal, such as copper, iron, aluminum, or others, or an alloy, such as steel, brass, bronze, or others. The legs 106 extend from the plate 102 away from the plate 102 and longitudinally along a length of the plate 102 such that the legs 106 oppose each other and a channel 108 is defined via the legs 106. Such opposition of the legs 106 enables the receptacle 104 to have a U-shape, C-shape, or V-shape cross-section. At least one of the legs 106 is externally and internally smooth, but can include depressions, projections, grooves, bores, maters, fasteners, magnets, adhesives, or other structures.

[0050] FIG. 2 shows an embodiment of a tube engagement unit engaging a tube while resting on a block with a well such that the tube is positioned within the well according to this disclosure. The tube engagement unit 100 retains a tube 1 12 in the channel 108 between the legs 106. The tube 1 12 can be retained via inward pressure via the legs 106 onto the tube 1 12, such as via friction. In some embodiments, the tube 1 12 is secured to the receptacle 104 via adhering, magnets, fastening, mating, or other ways. The tube 1 12 is used for underfloor fluid conduction, such as for radiant heating or cooling. For example, the tube 1 12 can conduct a liquid, such as water, or a mixture of liquids, such as water and alcohol or antifreeze or salt.

[0051] The tube engagement unit 100 is supported via a block 1 14, such as a sleeper, which contains a well 1 16 therein such that the tube 1 12 within the channel 108 is positioned within the well 1 16. The well 1 16 can be C-shaped, U-shaped, or V- shaped in cross-section. The tube 1 12 can be in contact with a bottom surface of the well 1 16 or avoid contacting the bottom surface 1 16 such that a gap exists

therebetween. Similarly, the legs 106 can be in contact with a sidewall of the well 1 16 or avoid contacting the sidewall such that a gap exists therebetween. The block 1 14 includes a thermally insulating material, such as wood, such as plywood. Although the block 1 14 is shown as a single block 1 14, a pair of the blocks 1 14 can be positioned immediately adjacent to each other in order to define the well 1 16. For example, the pair of blocks 1 14 can be symmetrical to each other, although the pair of blocks 1 14 can be asymmetrical to each other or be identical to or different from each other in any physical property, such as shape, size, constituency, conductivity, coatings, or others.

[0052] FIG. 3 shows an embodiment of a tube engagement unit being positioned in context of a subfloor and a finished floor where the tube engagement unit is supported via a pair of tailless blocks 1 14a, 1 14b according to this disclosure. The tube

engagement unit 100 is positioned in context of a subfloor 1 18 and a finished floor 120, which oppose each other. Each of the blocks 1 14a, 1 14b is tailless, is positioned between the subfloor 1 18 and the finished floor 120, and includes a ledge 122 and a wall 124 defining the ledge 122. The blocks 1 14a, 1 14b are trapezoidal in cross-section, but other shapes are possible, whether symmetric or asymmetric, such as square, a rectangle, a triangle, an oval, a circle, or any other polygonal or non-polygonal shape. The subfloor 1 18 and the blocks 1 14a, 1 14b define the well 1 16 therebetween, in which the tube 1 12 extends, while avoiding contact with the subfloor 1 18 such that a gap exists therebetween. The plate 102 is supported via the ledges 122 such that the plate 102 is between the walls 124. In some embodiments, the plate 102 can be contacting at least one of the walls 124. The legs 106 avoid contact with the blocks 1 14a, 1 14b, while extending toward the subfloor 1 18. The finished floor 120 faces the blocks 1 14a, 1 14b and the plate 102. The finished floor 120 can be in contact with the plate 102.

[0053] FIG. 4 shows an embodiment of a tube engagement unit being positioned in context of a subfloor and a finished floor where the tube engagement unit is supported via a single block according to this disclosure. In contrast to FIG. 3, the tube

engagement unit 100 is supported via a single block 1 14, which defines the well 1 16 therein. The tube 1 12 is in contact with the bottom of the well 1 16.

[0054] FIG. 5 shows an embodiment of a tube engagement unit being positioned in context of a subfloor and a finished floor where the tube engagement unit is supported via a pair of tailed blocks according to this disclosure. In contrast to Figs. 3 and 4, the tube engagement unit 100 is supported via a pair of tailed blocks 1 14a, 1 14b positioned immediately adjacent to each other, where each of the tailed blocks 1 14a, 1 14b includes a first elongated tail 124a, 124b and a second elongated tail 126a, 126b, respectively. As such, the tailed blocks 1 14a, 1 14b define the well 1 16, where the tube 1 12 avoids contact with the tails 124a, 124b, while the legs 106 avoid contact with the tailed blocks 1 14a, 1 14b. In some embodiments, at least one of the tails 124a, 124b, 126a, 126b can be configured for fastening, mating, adhering, interlocking, magnetizing, or other securing ways to other tails, blocks, surfaces, walls, or other structures.

[0055] Figs. 6 and 7 show an embodiment of an installation having a plurality of tube engagement units according to this disclosure. The tube engagement units 100 are supported via the blocks 1 14a, 1 14b, 1 14c, 1 14d, where the tube engagement units 100 and the blocks 1 14a, 1 14b, 1 14c, 1 14d alternate in a rectilinearly parallel manner, although other configurations are possible, as disclosed herein. The tube engagement units 100 and the blocks 1 14a, 1 14b, 1 14c, 1 14d are positioned between a plurality of blocks 130, such as a plurality of sleepers.

[0056] The blocks 130 define a plurality of bores 138 bored therethrough, such as for fastening to the subfloor 1 18. The bores 138 are circular, but other shapes are possible, such as ovoid, elliptical, or others. The bores 138 are smooth, but may be threaded. The bores 138 are identical in shape and size, but can differ in shape, size, or any other characteristic, including positioning. The bores 138 host a plurality of fasteners 140, such as screws, bolts, nails, or others, whether identical to or different from each other in structure, function, or positioning. The fasteners 140 fasten the blocks 130 to the subfloor 1 18. Similarly, the bores 1 10 host a plurality of fasteners 128, such as screws, bolts, nails, or others, whether identical to or different from each other in structure, function, or positioning. The fasteners 128 fasten the tube engagement units 100 to the blocks 1 14a, 1 14b, 1 14c, 1 14d.

[0057] The blocks 130 define a plurality of U-shaped trenches 132 and a plurality of arcuate trenches 136. Each of the U-shaped trenches 132 includes a first open end portion and a second open end portion. Each of the arcuate trenches 136 includes a first open end portion and a second open end portion. As fully assembled, the first open end portions and the second open end portions of the U-shaped trenches 132 and the arcuate trenches 136 are aligned with the channels 108. Therefore, the tube 1 12 is routed in a serpentine manner via the tube engagement units 100, as supported via the blocks 1 14a, 1 14b, 1 14c, 1 14d, and via the U-shaped trenches 132 and via the arcuate trenches 136. Note that a plurality of portions 134 of the tube 1 12 in the U-shaped trenches 132 and in the arcuate trenches 136 are exposed.

[0058] FIG. 8 shows an embodiment of a U-shaped cover according to this disclosure. FIG. 9 shows an embodiment of a U-shaped cover covering a U-shaped trench such that a tube is positioned therebetween according to this disclosure. A U- shaped cover 142 structured to cover the U-shaped trench 132 such that the tube 1 12 extends between the U-shaped trench 132 and the U-shaped cover 142. The U-shaped cover 142 may be unsecured to the block 130 or adjacent blocks 1 14 or secured to the block 130 or adjacent blocks 1 14. For example, such securing can be via fastening, mating, adhering, magnetizing, nailing, or other securing techniques. The U-shaped cover 142 includes a thermally conductive material, such as metal, such as copper, iron, aluminum, or others, or an alloy, such as steel, brass, bronze, or others. The U-shaped plate 142 is solid, but can be perforated. The U-shaped plate 142 is planar and flat, but variations are possible, such as via depressions or projections. The U-shaped cover 142 can include a bore or can include a magnetic area. The U-shaped cover 142 extends longitudinally as a rectangular strip, but variations are possible, such as trapezoidal or others. In some embodiments, the arcuate trench 136 is covered with an arcuate cover, which may be similar to the U-shaped cover 142, as disclosed herein, such as when the arcuate trench 136 does not return back towards the block 1 14d and runs rectilinearly along the block 130 or away from the block 130, such as to form an S- shape. Note that the plate 102 and the U-shaped cover 142 shield the tube 1 12 from puncture, such as from nails or sharp objects, or external pressure, such as a dropped heavy object or a worker foot, or others undesired forces or objects. As such, the plate 102 or the U-shaped cover 142 acts as a heat transfer plate while also providing a structural protection to prevent undesired forces, such as nails or screws, from

penetrating into the tube 1 12 during flooring installation.

[0059] In one or more embodiments, the U-shaped cover 142 is coupled to the tube 1 12 using a compound, such as, for example, a heat sink compound. In one or more embodiments, the heat sink compound is an adhesive, such as, for example, glue, paste, silicone, gel, epoxy, urethane, acrylate, or other adhesives. In one or more embodiments, the compound includes a thermally conductive, metal oxide powder, such as, for example, aluminum oxide, boron nitride, zinc oxide, aluminum nitride, or other metal or metal oxide, metal boride or metal nitride powders. In one or more

embodiments, the heat sink compound is used to couple the tube engagement unit 100 to the tube 1 12 in place of or in addition to the legs 106.

[0060] In one or more embodiments, each of the blocks 130, includes sub-blocks 131 , 133, and 135 positioned between the subfloor 1 18 and the finished floor 120.

Each of the sub-blocks 131 have semi-circular and/or quarter circular cutouts. Each of the sub-blocks 133 are semi-circles, and each of the sub-blocks 135 are quarter circles. In one or more embodiments, each of the sub-blocks includes a ledge and a wall defining the ledge. In one or more embodiments, the sub-blocks 131 , 133 and/or 135 have an angular cross-section on the curved edges, but other shapes are possible, whether symmetric or asymmetric, such as square, a rectangle, a triangle, an oval, a circle, or any other polygonal or non-polygonal shape.

Each of the first mode of installation 150, the second mode of installation 160, and the third mode of installation 170 is shown in cross- section, with each layer identified in a part list on respective Figs. 15-17.

[0066] FIG. 18 shows a jig for spacing apart a plurality of blocks according to this disclosure. A jig 180 includes an elongated block 182, a handle 184, and a plurality of legs 186. The handle 184 is secured to the block 182, such as via fastening, mating, magnetizing, adhering, or other securing techniques, whether removably or irremovably. The legs 186 are secured to the block 182 via fastening, but other securing techniques, such as mating, magnetizing, adhering, or others, can be used, whether removably or irremovably. At least one of the legs 186 is L-shaped as defined via a stem and a tail, with the block 182 facing the stem and the tail enveloping the block 182 such that the block 182 contacts the tail or against the tail. The legs 186 are spaced apart from each other and extend transversely to the block 182.

[0067] The block 182 can include wood, plastic, metal, or other materials. The block 182 is shaped as a cuboid, but other shapes are possible, such as pyramid, trapezoidal prism, a cube, a hemisphere, or others. The block 182 is solid, but can be perforated. The block 182, on any surface, can be longitudinally marked with a graduated scale, such as a ruler, whether grooved thereon or written thereon in a visually or touch distinct manner. The handle 184 can include wood, plastic, metal, or other materials. The handle 184 is U-shaped, but can be shaped differently, such as an L-shape, a V- shape, or others. At least one of the legs 186 can include wood, plastic, metal, or other materials. When at least one of the legs 186 is removably secured, then that leg 186 can be moved along the graduated scale and secured along the graduated scale. The jig 180 can include a level, such as a bubble level or a spirit level, including a multi- liquid container level for various measurements. The level can be secured to or integrated with the block 182, the handle 184, or at least one of the legs 186. [0068] In one mode of operation, the jig 180 is used in a method for establishing a proper spacing of between blocks 1 14 the tube 1 12 and the tube engagement unit 100. For example, in context of FIG. 3, the method includes positioning a first block 1 14a on a surface, such as the subfloor 1 18, where the first block 1 14a includes a first ledge 122a and a first wall 124a. The method includes positioning a first leg 186a of a segment, such as the block 182, on the first ledge 122a against the first wall 124a, where the segment includes a second leg 186b. The method includes positioning a second block 1 14b on the surface, where the second block 1 14b includes a second ledge 122b and a second wall 124b, where the first wall 124a faces the second wall 124b. The method includes positioning the second leg 186b on the second ledge 122b against the second wall 124b. The method includes securing the second block 1 14b to the surface. Therefore, the blocks 1 14a, 1 14b can be equally spaced.
