The present application generally relates to the field of laying and leveling tiles. More particularly, the invention is directed to a device for aligning and leveling tiles as they are laid in floors, walls, countertops, or the like.
Tiling is a laborious and time intensive endeavor. Tile installers spend a great deal of time aligning and leveling tiles as the tiles are being placed on a substrate's surface. Proper alignment, spacing and leveling of each tile is important because if one tile is improperly placed the error will propagate in adjacent tiles making the entire installation unacceptable. Laying and leveling tile can also be difficult to perform because many substrates are uneven.
Tile installers have used a variety of devices and methods to maintain quality tile installation while completing the installation process. However, conventional devices and techniques are labor intensive, expensive, time consuming and inefficient. For example, commercial systems on the market use a separate base for every grout or spacer size, requiring the purchase of a different base for each grout size.
The present disclosure relates to improving the aligning, spacing and leveling of adjacent tiles as they are laid in floors, walls, countertops, and the like. The present disclosure provides significant and non-obvious advantages over the foregoing disadvantages inherent in the prior art by providing an improved tile spacer and levelling device to assist installers to properly space and align a plurality of floor tiles to a uniform consistent width from adjacent tiles.
The present disclosure is directed to a tile leveling and alignment device, system, and method for use in aligning and leveling a plurality of tiles that are being secured to any suitable substrate, such as floors, walls, countertops, or the like.
According one exemplary embodiment disclosed herein, a tile leveling and aligning device comprises a main body comprising a base portion integrally coupled to a stem portion projecting upwards from the base portion. The base portion being adapted for engaging a bottom surface of a number of tiles to be leveled and aligned. The stem portion comprising a central aperture, which may be threaded, and one or more spacer legs or fins, each spacer leg extending transversely from the central aperture. Each spacer leg including external threads integrally formed on an outer face, defining a joint width between adjacent tiles to be leveled and aligned. Each of the equal sized areas being adapted to receive a corner of a tile, and dividing the tile leveling and aligning device into equal sized areas of common shape. Each spacer leg defines a joint width between adjacent tiles to be leveled and aligned.
According to a further aspect of one exemplary embodiment disclosed herein, a horizontal leveling device is provided. The horizontal and leveling device is adapted and configured to perform horizontal alignment of a number of tiles to be leveled and aligned. The horizontal leveling device comprises a locking-nut or the like for engaging the external threads of the spacer legs of the stem portion of the tile leveling and aligning device to cause adjacent tiles be drawn down into a properly spaced relative horizontal arrangement. By applying a circular or rotational horizontal leveling force directly to the stem portion of the tile leveling device, via engagement with the horizontal leveling device, the tops of the tiles are horizontally aligned together in the same plane into a properly spaced relative horizontal arrangement with minimal or no slippage.
According to a still further aspect of one exemplary embodiment disclosed herein, a vertical leveling hand device is provided. The vertical leveling hand device is adapted and configured to perform a horizontal alignment of a number of tiles to be leveled and aligned. In those cases where it is determined that the tiles must be raised vertically to bring them in line with the horizontal, the vertical leveling hand device is adapted and configured to impart an upward vertical force on the tiles. In an embodiment, the vertical leveling hand device comprises a T-bar having a stem gripping portion for gripping the stem, and a threaded tile leveler engagement portion for threaded (or non-threaded) engagement with the stem portion of the tile leveling device. In operation, engagement of the T-bar engagement portion with the stem portion of the tile leveling device imparts a vertical force on a portion of the substrate directly beneath the tiles to be aligned causing the tiles to be driven in the vertical direction thereby causing leveling of the tiles so that adjacent tiles are leveled relative to themselves without regard to whether the substrate material is level. The force applied by the vertical leveling hand device holds the tiles at the same height so that corners and/or edges of the adjacent tiles remain level in the setting bed as the setting bed dries and cures. After the setting bed dries, thereby securing the tiles to the substrate, the stem portion can be separated from the bottom plate leaving the bottom plate beneath the set tiles.
According to a still further aspect of the one exemplary embodiment disclosed herein, an optional slip ring/spacer device is provided. The slip ring/spacer device is adapted and configured for dual use, first as a slip ring/spacer in a first orientation and for exclusive use as a slip ring in a second orientation. The slip ring feature of the device substantially eliminates horizontal shifting of a number of tiles to be leveled and aligned as they are being horizontally aligned by the horizontal leveling device, as described above. In operation, the slip ring is placed directly over the stem portion of the tile leveling and aligning device directly beneath the horizontal leveling device and is seated on top of a number of tiles to be leveled and aligned surrounding the tile leveling device. In an embodiment, the slip ring/spacer device comprises a circular disk including a hollowed cross-sectional area and four integrally molded raised protrusions formed at a bottom side of the device for non-edge applications. In one embodiment the slip ring/space comprises a circular disk including a hollowed cross-sectional area and two integrally molded raised protrusions formed at a bottom side of the device for edge applications. In each of the described embodiments, the raised protrusions have a common length and are circumferentially and equidistantly spaced about the periphery of a bottom side of the device. The spacer feature of the device provides flexibility by providing spacings greater than 1/16″ which cannot be realized by the tile leveling device alone which is best suited to provide tile spacing of 1/16″ by the nature of its construction. When used in a first orientation as a spacer, the integrally molded raised rectangular protrusions are oriented to face towards the tiles. The slip ring/spacer device is manufactured with a range of rectangular protrusion widths according to different desired tile spacings (e.g., ⅛″, ¼″, ½, etc).
According to one aspect of the exemplary embodiments disclosed herein, the stem portion includes a number of vertical legs or projections corresponding to the number of tiles to be leveled.
According to one aspect of the exemplary embodiments disclosed herein, the vertical projections (spacer fins) of the stem portion of the tile leveling device include a frangible breakaway section to facilitate breakaway from the base portion after the tiles have been set.
According to one aspect of the exemplary embodiments disclosed herein, the stem portion is frangibly molded onto the base portion at a breakage point at the time of fabrication.
According to one aspect of the exemplary embodiments disclosed herein, the optional slip ring/spacer is made from a non-conductive material, such as a hard plastic and may have an external cylindrical shape including one or more through slits to slip over the one or more vertical legs of the spacer member. In the particular case of leveling four vertical legs, the slits of the slip ring/spacer form a hollowed cruciform or cross-shaped configuration.
According to one aspect of the exemplary embodiments disclosed herein, the tile alignment and leveling device may be constructed of any suitable material, and is comprised of a plastic material which may be readily produced, such as by molding.
According to one aspect of the exemplary embodiments disclosed herein, a method for aligning and leveling tiles being secured to a suitable substrate comprises steps of: applying a setting bed, placing a plurality of tiles in the setting bed, positioning the tile device at an intersection of two, three or four adjacent tiles in the setting bed, such that each tile abuts a corner of a stem portion of a tile device thereby spacing the two, three or four adjacent tiles to be aligned at a predetermined distance with respect to each other, applying a circular or rotational horizontal leveling force to the stem portion, via a horizontal leveling device, to cause the top of the tiles to be horizontally aligned together in the same plane with minimal or no slippage, thereafter applying a vertical force to the substrate beneath the tiles to be leveled, via a vertical leveling hand device, resulting in a counter force thereby lifting or lowering the tiles in a vertical direction to cause alignment of the tiles.
The method further comprising steps of: separating the spacer member of the plurality of tiles devices from the base plate member leaving the base plate member beneath the set tiles.
The present disclosure also relates to a tile leveling and aligning system, according to an exemplary embodiment, comprising: a tile leveling and aligning device comprising a main body comprising a base portion integrally coupled to a stem portion, the base portion adapted for engaging a bottom surface of a number of tiles to be leveled and aligned, the stem portion projecting upwards from the base portion and having one or more spacer legs extending transversely from a center aperture of the stem portion, each spacer leg having a series of external threads integrally formed on an outer face, the one or more spacer legs dividing the base portion into equal sized areas of common shape, each of the equal sized areas adapted to receive a corner of one of the tiles to be leveled and aligned, each spacer leg defining a joint width between adjacent tiles to be leveled and aligned, a horizontal leveling device for engaging a top surface of the number of tiles to be horizontally leveled and aligned, the first horizontal leveling device adapted and configured to engage the spacer legs formed on the outer face of the stem portion of the tile leveling and aligning device, the engagement resulting in a single connected assembly comprising the tile leveling and aligning device, the horizontal leveling device and the number of tiles to be leveled and aligned, a vertical leveling hand device adapted for imparting a vertical force on a substrate beneath the number of tiles to be leveled and aligned, the vertical force causing the single connected assembly to be driven upwards away from the substrate resulting in a vertical alignment of the tiles.

Referring to
As best shown in
With continued reference to
In some embodiments, as described further below, the orifice 38 of the base portion 20 of the tile spacer device 10 and the vertical leveling hand device 26 may be non-threaded depending on the application.
Referring again to
As shown in
In an embodiment, a method for aligning and leveling a plurality of tiles includes a first step of applying a setting bed 54, such as a cement or mortar compound, to the substrate surface 58. A plurality of tile spacer devices 10 are then positioned in the setting bed 54. Thereafter, the tiles 40 can be placed around each tile spacer device 10 in the setting bed 54 beneath the tiles 40 so that the spacer members 30 extend upward between the adjacent tiles 40, as best shown in
After the tile spacer devices 10 have been positioned in the setting bed 54, a user may perform the optional step of placing slip ring/spacers 50 over the respective stem portions 30 of the tile spacer devices 10, after the tile spacer device 10 has been embedded in the setting bed 54 to eliminate any horizontal shifting of the tiles as they are being horizontally aligned by the horizontal leveling device 56 (e.g., locking nut).
Further structural details of the slip ring/spacer 50 are depicted in
The slip ring/spacer device 50, as its name implies, is configured to serve the dual functions of a slip ring and a tile spacer when oriented in a first orientation and solely as a spacer in a second orientation. As shown in
In accordance with a method of operation, according to one embodiment, after the slip ring/spacer 50 is placed over the stem portion 30 of tile spacer device 10, the horizontal leveling device 56 is then placed over the slip ring/spacer 50 and is threadedly engaged with the outer threads 34 of the four vertical projections 32a-d of the stem portion 30 of the tile spacer device 10. Upon engaging the horizontal leveling device 56 over the tiles 40, the horizontal leveling device 56 is turned in a clockwise or counterclockwise direction, dependent upon the threading arrangement, thereby causing a downward pressure to be exerted on the tiles 40 underneath which causes the edges/and or surfaces of the tiles 40 to be aligned in the same plane with minimal or no slippage. Thereafter, with the tiles aligned, the locking nut 56 remains in place and a threaded engagement portion 28 of a vertical leveling hand device 26 is inserted into the threaded orifice 38 of the tile spacer device 10 and turned in one of a clockwise or counterclockwise direction to align the tiles 40 vertically with respect to the floor or substrate 58 by exerting a downward force against the floor or substrate 54. The alignment may be verified by using a conventional leveling measurement device. Further alignment may be achieved by continued turning of the vertical leveling hand device 26 in either the clockwise or counterclockwise direction.
The horizontal leveling device 56, can be, for example, a locking nut, which in a preferred embodiment is a hexagonal locking nut, as shown, for example, in
Once the tiles 40 have been placed in vertical and horizontal alignment, the vertical leveling hand device 26 and horizontal leveling device 56 (e.g., locking nut) are removed from the tile spacer 10. Thereafter, once it has been determined that the setting bed has dried, the stem portion 30 may be separated from the base portion 20 of the tile spacer devices 10 leaving the base portions 20 beneath the tiles 40.
In accordance with the presently described embodiment, a vertical leveling hand device (e.g., T-bar) 76 includes a grip portion 77 and a non-threaded stem portion 78. Notably, the orifice 38 of the stem portion 30 of the tile leveling device 10 is also non-threaded in this embodiment. With the locking nut 56 secured in place, the T-bar 76 is inserted into the non-threaded orifice 38 of the stem portion 30 of the tile leveling device 10 without applying any force. Thereafter, the U-bar 70 is secured to the locking nut 56 at securing points 72a and 72b. Notably, the order of operation of insertion of the vertical leveling hand device (T-bar) 76 and securing the U-bar 70 to the locking nut 56 may be performed in any order.
With the vertical leveling hand device (e.g., T-bar) 76 and the U-bar 70 elements in place, a user, using the palm of the hand, would apply a downward force directly to the vertical leveling hand device (T-bar) 76 and simultaneously apply un upward force on the U-bar 70 using the fingers of the same hand so that the tiles 40 together with the locking nut 56 are collectively pulled in an upward direction until vertical alignment occurs. It is therefore appreciated that a lifting action of the tiles is achieved without the need to turn the vertical leveling hand device (T-bar) 76 and risk penetration of the substrate.
Referring now to
The alternate grout spacer 80 can be manufactured to various thicknesses to accommodate a wide variety of tile grout spacing. Notably, for those applications where both the alternate grout spacer 80 and the slip ring/spacer device 50 are used, the slip ring spacer device 50 would not serve as a grout spacer and would instead be oriented in a manner to function exclusively as a slip ring, i.e., with the vertical protrusions 52 facing the substrate (i.e., “B” side down), as shown in
As described above, three independent options for grout spacing are provided according to the present disclosure. A first option is provided by the width of the vertical projections 32a-d of the stem portion 30 of the tile spacer device. A second option is provided by the slip ring/spacer device 50. A third option is provided by the alternate grout spacer 80.
It is envisioned that other styles and configurations of the present system can be easily incorporated into the teachings of the present disclosure, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
Embodiments of the present system can be utilized by the common user in a simple and effortless manner with little or no training. After initial purchase or acquisition of the system, it would be installed as indicated in
One of ordinary skill in the art would understand that a plurality of tile alignment and leveling devices can be simultaneously used between different tiles being laid on a substrate so as to level many tiles at the same time.
