Definitions

• a flooring system that comprises a series of interlocking panels is installed above and in contact with a subfloor.
• the flooring may be formed of panels of natural wood, engineered flooring, laminate flooring or vinyl, vinyl tile, wood plastic composite, stone polymer composite, etc.
• each successive panel wooden or laminate planks or strips, etc., is forced against the previously positioned panel to make the flooring joints secure. This results in pushing the flooring under the vertical gap between the bottom of the drywall and the subfloor. This creates a problem during installation of the floor and creates a problem in not accommodating normal expansion of the flooring after the installation has been completed.

• the spacing apparatus 10 includes an elongated first element 20, preferably formed as a relatively thin, rectangular plate extending in a first direction and terminating at said first end 12, and having opposed first and second generally rectangular surfaces 22, 24 lying in generally parallel planes.
• the first element includes opposed edges connecting the surfaces 22, 24, and has a non-adjustable width“ ⁇ V” illustrated in FIGS. 2 and 7 measured in a direction across the surface 22 and thus perpendicular to the edges and perpendicular to the direction between the first end 12 and second end or surface 14.
• the first element 20 may have large openings 29 therethrough to reduce the weight of the spacing apparatus and also reduce the cost since less material is utilized when compared to a solid first element 20. The openings also facilitate grasping/moving the spacing apparatus.

In the orientation of FIG. 1, the first portion 16 extends away from and terminates above surface 22 and includes an interior wall 28 extending upwardly from surface 22 generally parallel to surface 14. First portion 16 is thus generally perpendicular to first element 20. First portion 16 further includes an end 30 oriented generally parallel to surfaces
• the interior wall 28 and surface 22 are generally perpendicular to each other and their intersection forms an internal shoulder 32.
• the interior wall 28 may be generally U-shaped 34 (as seen in the orientation of FIGS. 2 and 6) to reduce the weight of the spacing apparatus and also reduce the cost since less material is utilized.
• the base of the U-shape may extend across the width of the first element 20 and the legs of the U-shape may extend in the longitudinal direction of the spacing apparatus from the surface 14 toward the first end 12.
• the internal shoulder 32 is thus formed by the intersection of the vertical interior wall portions of the U- shape and the surface 22.
• the second portion 18 extends away from and terminates below surface 24 and thus in a direction opposite to the first portion relative to the first direction of the first element 20.

• width T-l is preferably approximately 1.27 cm and width T-2 is preferably approximately 0.635 cm. As will be explained below, these widths correspond to various generally preferred expansion gaps.
• the height of the ends 30, 38, measured from the surfaces 22, 24, respectively, preferably will be at least the anticipated thickness of the flooring.
• Non-limiting examples of the use of the spacing apparatus to properly position flooring away from the wall during installation of the flooring to create the desired expansion gap may be appreciated from consideration of the above and from the following reference to FIG. 4, FIG. 5 and FIG. 6.
• a non-limiting example of the use of the spacing apparatus to properly position flooring away from a doorway during installation of the flooring to create an expansion gap to allow for placement of a threshold may be appreciated from consideration of the above and in addition FIG. 7.
• the spacing apparatus 10 is positioned such that the second end or surface 14 abuts a vertical wall 44 which, for illustrative purposes, may be considered to be an interior wall of a house.
• the orientation of the spacing apparatus 10 is such that the projection element first portion 16 extends upwardly and the projection element second portion 18 extends downwardly, consistent with the orientation of the spacing apparatus 10 in FIG. 1.
• a spacing apparatus 10 is positioned against the vertical wall and an elongated laminated flooring plank 46 is positioned on a subfloor 50 and below the first element 20 of the spacing apparatus 10. The edge 47 of the flooring plank closest to the vertical wall is positioned to abut the internal shoulder 32.
• multiple spacing apparatus should be positioned along the length of the wall (and thus along the length of the flooring planks) and one or more additional spacing apparatus should be positioned at the end of the plank adjacent a wall (not shown) perpendicular to the wall 44, for example as would be typical in the corner of a room in a house.
• an expansion gap is created and maintained between the vertical wall 44 and edge 47 of the flooring planks 46, the gap having a width“T-2” corresponding to the thickness“T-2” of the projection element second portion 18.
• This thickness which is approximately 0.635 cm in one non-limiting embodiment may be preferred for laminated vinyl flooring, laminated vinyl tile, stone polymer composite and wood/ plastic composite flooring, and has been found suitable to accommodate anticipated expansion for these types of flooring.
• the positioning of the spacing apparatus with the surface 24 on top of the flooring plank 46 aids in maintaining the flooring plank in position during installation and also prevents the spacing apparatus 10 from pivoting out of position.
• the spacing apparatus 10 is easily removable after a suitable number of flooring planks 46 have been placed in position such that the spacing apparatus 10 may be reused.
• the projection element first portion 16 above the surface 22 generally allows the spacing apparatus 10 to be supported against the vertical wall notwithstanding the expansion gap between the vertical wall and the top of the flooring plank 46.
• the spacing apparatus 10 should be oriented or inverted relative to the position in FIG. 1., FIG. 4 and FIG. 6 such that the projection element first portion 16 extends downwardly between the vertical wall 44 and the edge 47 of the flooring plank 46, again with the first element, and more particularly surface 22 positioned on top of the flooring plank 46.
• the height of the projection element second portion 18 above the surface with the first element 20 supported on the flooring plank, the projection element first portion 16 above the surface 22, generally allows the spacing apparatus 10 to be supported against the vertical wall 44 notwithstanding the expansion gap between the vertical wall and the top of the flooring plank 46.
• the expansion gap between the vertical wall and the ends of the flooring planks 46 would correspond to the width“T-l” which is approximately 0.127 cm in a non-limiting embodiment.
• An expansion gap is formed between the vertical wall 44 and edges 47 of the planks 46, the gap having width“T-l” corresponding to the thickness“T-l” of the projection 16 and a gap of this width may be preferred for engineered wood, laminated wood and solid wood flooring which tend to expand a greater distance than the types of flooring described with reference to FIGS. 4 and 6.
• the spacing apparatus 10 is removable after a suitable number of flooring planks 46 have been installed.
• the spacing apparatus 10 provides the advantage that the expansion gaps need not be the same, rather, the installer of the flooring system may use different expansion gaps.
• creating a horizontal expansion gap during installation of the flooring system is not the sole benefit of the spacer 10.
• Conduits including but not limited to electrical, plumbing and/ or ventilation conduits may be placed within the vertical gap without interference from the flooring 46 and the conduits will subsequently be concealed by moulding.
• the physical height of the spacer portion ends 30 and 38, measured from surfaces 22 and 24, respectively, are not limited by the thickness of the flooring system 46.
• a flooring system may be installed adjacent a doorway and an expansion gap may be provided to accommodate expansion and to receive a threshold.
• a spacing apparatus 10 is rotated 90° to the orientation in FIG. 7 relative to orientation of the spacing apparatus in each of FIGS. 1, FIG. 2, and FIG. 3.
• the subflooring 50 is illustrated and a previously installed floor 52, having an edge or vertical surface 53 is illustrated such as adjacent a doorway where there is no corresponding vertical wall 44.
• the surface or second end 14 of the spacing apparatus 10 is preferably placed on the sub floor, as contrasted to the second end 14 being placed against a vertical wall, and oriented such that an expansion gap having a non-adjustable width“ ⁇ V” is created between the edge 53 of the existing floor 52 and the edge 47 of the flooring planks 46 that are being installed.
• this width“ ⁇ V” is 2.54 cm which has been found to be sufficient to accommodate a conventional threshold.
• the flooring planks and existing floor each abuts the opposite narrow edges of the first element 20.
• Conventional thresholds are frequently T-shaped with the horizontal top of the T used to cover a gap between flooring in adjoining rooms and with the vertical leg of the T to be inserted in the gap between flooring in adjacent rooms and/ or between flooring and doorway to the exterior.
• the spacing apparatus 10 may be oriented as illustrated in
• FIG. 7 but with one edge of spacer first element 20 abutting a vertical wall, rather than the vertical edge 53 of a previously installed floor 52 and with the flooring plank 46 abutting the opposite narrow edge of the spacer first element 20.
• the expansion gaps using the spacing apparatus 10 is not limited or restricted to providing space for a threshold.
• spacing apparatus 10 may be positioned at regular intervals along the length of the floor. If, for example the floor is formed of a series of planks 46 of 15.24 cm width and 182.88 cm length, then spacing apparatus may be placed every 30.48 cm along the length of a flooring plank and one spacing apparatus may be placed at the end of each flooring plank where the flooring plank would otherwise contact the wall.
• the spacing apparatus 10 provides a reusable apparatus that provides for three different size non-adjustable expansion gaps relative to the flooring system and, in a preferred embodiment, the three different size non-adjustable expansion gaps are approximately 0.625 cm, 1.27 cm and 2.54 cm, respectively.
