DETAILED DESCRIPTION

[0028] Before any embodiments of the disclosure are explained in detail, it is to be understood that the 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 following drawings. The disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of including, comprising, or having and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.

[0029] FIG. 1 shows a plan view of an underlayment section 1 in accordance with embodiments of the present disclosure. The underlayment section 1 includes a number of routing hubs 2, comprising four protrusions 2a arranged in an equally-spaced circular array about an array axis 2b, in a matrix configuration. The matrix is configured in the form of an eight row by twelve column matrix of routing hubs 2. The matrix provides heating element receiving cavities 3 in the X-direction, Y-direction, and in directions approximately 45 degrees to the X-direction and/or the Y-direction. A sample routing 4 of the heating element 5 is shown in FIG. 1. In particular, the heating element section 5 shown runs along the Y-direction between the first and second columns of routing hubs 2, proceeds around the routing hub 2 in the first row and second column (2, 8) and along the negative Y-direction between the second and third columns to the (3, 1) routing hub 2, proceeds along the Y-direction between the third and fourth columns until about the (3, 4) routing hub 2, and then proceeds diagonally through the heating element receiving cavities 3 in the (4, 5), (5, 6), (6, 7), and (7, 8) routing hubs 2, and so on.

[0030] FIG. 2 shows a cross-sectional view of an area of the underlayment 1 taken along line A-A. In some embodiments, one or more of the protrusions 2a can extend from the base material surface 6 to a contact surface 7. The contact surface 7 may be configured to support tile, flooring, or other material. The distance from the base material 6 to the contact surface 7 is called the protrusion height 7a. The thickness of the base material 6 is called the base thickness 6a. In some embodiments, the protrusions 2a may be formed from the base material 6, and as such, may have a wall thickness approximately equal to that of the base thickness 6a.

[0031] FIG. 3 shows a detail cross-sectional view of an area of the underlayment 1 in accordance with embodiments of the present disclosure. In one embodiment, the areas adjacent to each protrusion 2a can form a heating element receiving cavity 3. Each heating element receiving cavity 3 can include an interference fit 8, or contained area, to hold a heating element 5 or wire in place. In some cases, the heating element 5 may be inserted into the heating element receiving cavity 3 with a predetermined amount of force required to part (e.g., elastically deform, plastically deform, flex, and/or deflect, etc.) at least one of the receiving surfaces 9 of the cavity. In one embodiment, when the heating element 5 is inserted into the heating element receiving cavity 3 the at least one of the receiving surfaces 9 may return to an original position thereby closing the heating element receiving cavity 3 and containing the heating element 5.

[0032] FIG. 4 shows a detail plan view of a routing hub 2 of the underlayment 1 in accordance with embodiments of the present disclosure. The heating element receiving cavities 3 are shown disposed between protrusions 2a and/or routing hubs 2. In some embodiments, one or more of the heating element receiving cavities 3 can be configured differently from another heating element receiving cavity 3. For instance, several heating element receiving cavities 3 may be configured to provide a frictional fit for holding a heating element 5, while other heating element receiving cavities 3 may be configured to merely contain a heating element 5. In any event, the underlayment 1 can include one or more configurations of heating element receiving cavity 3.

[0033] FIG. 5 shows a plan view of routing hubs 2 of an underlayment 1 in accordance with a first embodiment of the present disclosure. As described above, the protrusions 2a, base material 6, and/or other features of the underlayment 1 may include a number of cutouts 10, or holes. In some embodiments, the cutouts 10 can extend at least partially into the protrusion 2a, base material 6, and/or the underlayment 1. In some embodiments, the cutouts 10 are shown as extending at least partially into at least one side of at least one protrusion 2a.

[0034] FIG. 6 shows a plan view of routing hubs 2 of an underlayment 1 in accordance with a second embodiment of the present disclosure. The underlayment 1 section includes a number of routing hubs 2, comprising four protrusions 2a arranged in an equally-spaced circular array about an array axis 2b, in a matrix configuration. A sample routing 4 of the heating element 5 is shown in FIG. 6. In particular, the heating element section 5 shown runs along the Y-direction of the first column of routing hubs 2, proceeds around the routing hub 2 in the second row and first column (1, 2) and along the negative Y-direction between the first and second columns, and then proceeds diagonally through the heating element receiving cavity 3 in the (2, 1) routing hub 2.

[0035] FIG. 7 shows a detail cross-sectional view of a first embodiment of the routing hubs 2 taken along line D-D shown in FIG. 6. As shown, the heating element receiving cavity 3 in FIG. 7 includes arcuate receiving surfaces 9. The arcuate receiving surfaces 9 may be configured as concave, curvilinear, arched, and/or other shape configured to receive the heating element 5. In some cases, at least one of the arcuate receiving surfaces 9 of the routing hubs may be configured to contact the heating element receiving cavity 3. The contact may provide a frictional force that retains the heating element 5 in the underlayment 1. In some embodiments, the arcuate receiving surfaces 9 may contain the heating elements 5 in the heating element receiving cavity 5 without frictional contact.

[0036] Additionally or alternatively, the underlayment 1 may include a pad layer 11. The pad layer 11 may include a sound dampening material, heat reflective material, insulative material, porous substrate, vapor barrier, waterproof material, energy reflective material, etc., and/or combinations thereof. Examples of pad layers 11 can include, but are in no way limited to, foil, cork, rubber, plastic, concrete, wood, organic materials, inorganic materials, composites, compounds, etc., and/or combinations thereof. The pad layer 11 may be attached to the base material 6 via adhesive, thermal bonding, welding, mechanical attachment, etc., and/or combinations thereof. As can be appreciated, the pad layer 11 may include adhesive on the side opposite the base material 6 side for affixing to a surface, such as a subfloor, floor, etc. In one embodiment, the pad layer 11 may be configured to receive adhesive for affixing to a surface. It should be appreciated that any of the underlayment 1 embodiments as disclosed may include such a pad layer 11. In some embodiments, there may be additional pad layers 11, one above another (e.g., a stack of two, three, four, five, or more pad layers 11) for strengthening and controlling anti-fracture. This enables isolation of cracks in a substrate from traveling to the tile layer.

[0037] FIG. 8 shows a detail cross-sectional view of a second embodiment of the routing hubs 2 taken along line D-D shown in FIG. 6. As shown, the heating element receiving cavity 3 in FIG. 8 includes angular receiving surfaces 9. The angular receiving surfaces 9 may be configured as a draft angle 9a, a dovetail, a V shape, or other channel shape configured to receive the heating element 5. In some cases, at least one of the angular receiving surfaces 9 of the routing hubs 2 may be configured to contact the heating element receiving cavity 3. The contact may provide a frictional force that retains the heating element 5 in the underlayment 1. In some embodiments, the angular receiving surfaces 9 may contain the heating elements 5 in the heating element receiving cavity 5 without frictional contact.
