Abstract
The system includes receivers and wedges. Each receiver has a base and a perpendicularly-extending hook having an aperture. Each hook is disposed as a spacer between a pair of tiles in an array laid in bedding, to provide for side-by-side tile spacing. The base is disposed beneath the pair. Each wedge has a clamping surface and a ribbed gripping surface orientated angularly thereto. Each wedge extends through the aperture such that: the pair is captured between the base and wedge, with the clamping surface disposed in coplanar relation to the pair; the gripping surface grips the receiver, to resist wedge withdrawal and maintain the clamped engagement until the bedding has cured. The gripping surface width is less than the wedge width. The hook has a wall that defines one edge of aperture, is opposite to and presents towards the planar element in perpendicular relation. The wall fits between the ribs.
Description
- The invention relates to the field of tile.
- It is known to use wedge systems to facilitate the installation of tile.
- A known wedge system involves wedges and wedge receivers. Each wedge has a planar surface and a gripping surface orientated in angular relation to one another to meet in an end. The gripping surface has a plurality of arcuate ribs. Each wedge receiver has a generally planar base element and a hook element extending from the base element in substantially perpendicular relation. The hook element has an aperture defined therein. In use, tiles are laid in a generally conventional manner. The hook elements are used to space apart the tiles, with the base elements embedded or laid upon the mortar, adhesive or thin set bedding material. Each wedge element is inserted through a respective aperture and pushed forward in the direction of the end such that the tiles are captured between the base elements of the wedge receivers and the planar surfaces of the wedges; this causes the tiles to align. The ribbed surface of the wedge receiver provides for a tight and reliable grip. After the bedding material has set, the wedges are removed, the hook elements are separated from the base elements by a mallet and the tiles are grouted in a conventional manner.
- Forming one aspect of the invention is an improved wedge system of the type used with tiles and a bedding material such as mortar or adhesive for creating a tiled surface having an array of the tiles arranged in substantially coplanar side-by-side evenly spaced relation.
- The wedge system is of the type including:
-
- wedge receivers, each having a substantially planar base element and a hook element extending from the base element in substantially perpendicular relation: the hook element having an aperture defined therein, each hook element, in use, being disposed in the manner of a tile spacer between a pair of adjacent tiles in an array of the tiles laid in the bedding material, thereby to provide for said substantially even side-by-side spacing of the tiles and the base element, in use, being disposed beneath the pair of adjacent tiles; and
- wedges, each having a clamping surface and a ribbed gripping surface orientated in angular relation to one another, each wedge, in use, extending through the aperture of a respective receiver such that:
- the pair of adjacent tiles are captured between the base element and the wedge, with the clamping surface of the wedge disposed in coplanar relation to the pair of adjacent tiles; and
- the gripping surface grips the respective wedge receiver, to resist withdrawal of the wedge from the aperture and maintain the clamped engagement until the bedding material has cured,
- The improvement comprises:
-
- the gripping surface of the wedge having a width less than the width of the wedge; and
- the hook element having a wall that defines one edge of the aperture and is disposed opposite to and presents towards the base element in perpendicular relation, the wall being sized to fit between the ribs.
- According to another aspect, the ribs can be arcuate.
- According to another aspect, the wall can taper in width as it extends away from the planar portion.
- According to another aspect, the wedge, when sectioned perpendicular to the clamping surface, has a profile which terminates in a portion that has the shape of the wall.
- According to another aspect, the system can further comprise slider plates, each slider plate being planar and having a slot adapted to permit through passage of a hook.
- Advantages, features and characteristics of the present invention will become apparent to persons of ordinary skill upon review of the following detailed description with reference to the appended figures, the latter being briefly described hereinafter.

FIG. 12B is a side view of the structure ofFIG. 12A ; -
FIG. 13 is a view similar to 12 with the structure ofFIG. 3 extending through the structure ofFIG. 2 more fully than as shown inFIG. 12 ; -
FIG. 13A is an enlarged view of encircledarea 13A ofFIG. 13 ; and -
FIG. 13B is a side view of the structure ofFIG. 13A . - The
components 20 of an improved wedge system are shown inFIG. 1A to 1E and will be seen to includewedge receivers 22,wedges 24 andslider plates 26. - With reference to
FIG. 2 , thewedge receivers 22 each have abase element 28 and ahook element 30. - The
base element 28 is generally hourglass-shaped in plan [as shown inFIG. 1A ], terminating in a plurality offeet 32, and is generally planar. However, when viewed in profile, as indicated inFIG. 1D , it will be seen that thebase element 28 is generally thickest along a centerline C-C and generally tapers as it extends away therefrom, but for aridge 34 defined by eachfoot 32. - The
hook element 30 extends from the centerline of the base element, includes a pair oflegs 36, abridge 38 and awall 40 and defines anaperture 42. - The
legs 36 have generallycoplanar portions 44 and meet the base 28 inwaisted portions 46. - The
bridge 38 rigidly connects thelegs 36. - The
wall 40 is resilient, defines one edge of theaperture 42 and is disposed opposite to and presents towards thebase element 28 in perpendicular relation. Thewall 40 tapers in width as it extends away from thebase element 28 and has a thickness. - With reference to
FIG. 3 andFIG. 1B , thewedges 24 will be understood to each have: -
- a clamping surface 48 (not shown, but understood to be the underside)
- a
gripping surface 49 orientated in angular relation to the clampingsurface 48 to meet in anend 50; - opposite the
end 50, abase 52; - a pair of
sides 54 projecting in perpendicular relation to the clampingsurface 48 and in parallel relation to one another; and -
chamfers 56 flanking the grippingsurface 49, each extending from the grippingsurface 49 to arespective side 54.
- The clamping
surface 48 is planar. - The gripping
surface 49 has a width W1 less than the width W2 of the wedge and is defined by a plurality ofarcuate ribs 58 spaced apart by about the thickness of thewall 40. The arcuate nature of theribs 58 is best seen in plan, as inFIG. 1B . - The
end 50 defines a plurality ofsteps 60, eachstep 60 demarcated with its thickness relative to the clampingsurface 48. - The
base 52 defines aconcave surface 62. - The
sides 54 are planar and parallel. - The
chamfers 56 have a plurality of equally spaceddemarcations 64 and are shaped such that thewedge 24, when sectioned perpendicular to the clampingsurface 48, has a profile which terminates in a portion that has a shape and size that generally matches that of thewall 40. - With reference to
FIG. 4 , theslider plates 26 are each planar, each have aslot 66 adapted to permit through passage of ahook 30 and are generally cruciform in shape. Eacharm 68 of the cross is demarcated with its thickness relative to abase 70 of the plate. Again,base 70 is not shown but will understood to be a planar surface on the underside. - The usefulness of the components will become evident upon review of the sequence of
FIG. 5 through 13B . More particularly: -
- bedding material of, for example, thinset mortar, is placed as in
FIG. 5 - a tile is placed on the bedding material as in
FIG. 6 -
receivers 22 are disposed around the perimeter of the tile with portions of the base elements disposed beneath tile, as shown in phantom inFIG. 7 - additional tiles are placed, such that (i) the
hook elements 30 are disposed in the manner of tile spacers between pairs of adjacent tiles in an array of the tiles laid in a bedding material, thereby to provide for said substantially even side-by-side spacing of the tiles; and (ii) thebase elements 28 are disposed beneath the pairs of adjacent tiles, as inFIG. 8 -
slider plates 26 are fitted over thehook elements 30 such thathook elements 30 protrude therethrough, as inFIG. 9 andFIG. 10 -
wedges 24 are pushed through thehooks 30, as indicated by sequence ofFIGS. 8-10 , with the pairs of tiles captured between theslider plates 26 and thebase elements 28 andgripping surfaces 49 engaging thereceivers 22 to resist withdrawal of thewedges 24 until the bedding material has cured.
- bedding material of, for example, thinset mortar, is placed as in
- It will be appreciated that interposing
slider plates 26 between the clamping surfaces 48 and the tiles prior to placement of thewedges 24 isolates the underlying tiles from frictional engagement with thewedges 24 thereby avoiding translation movement. To restate: prior art wedge systems, when tightened, can cause separation of the underlying tiles by virtue of frictional forces; interposition of theslider plate 26, which is locked against motion by engagement with thehook 30, resists this. - Of course, the wedges and wedge receivers can be used in a generally conventional fashion that is, without slider plates. However, even in this use, the components of the system have advantage. More particularly, the system of the present invention is relatively easy to use without hand tools in comparison to known systems, even that disclosed in WO 2015/161366, incorporated by reference. Without intending to be bound by theory, it is believed that the reduced size of the gripping surface and the complementary shaping of the wall and the upper profile of the wedge may account for that ease of use.
FIGS. 13A and 13B are close ups showing the manner in which the wall is deformed in use; again, without intending to be bound by theory, it is believed that the shape of the wedge and the shape of the wall cooperate such that the wedge relatively easily deforms the wall to a position whereat the engagement of the wall in the ribs robustly resists withdrawal. - The system has even further advantage, including, without limitation:
-
- the demarcated thicknesses on the slider plates and wedge ends allow the slider plates and wedges to be used as tile spacers when desired.
- the demarcations along the chamfers facilitate clamping on the tiles to a generally consistent pressure, which can have advantage in terms of install quality.
- the tapered feet of the base elements facilitate insertion of the clips under the tiles and into the bedding material; the ridges on the feet provide rigidity to the feet and maintain the thickness of the feet, again, providing advantages in terms of install quality.
- the waisted portions of the legs facilitate removal of the clips with a mallet after the bedding material has cured.
- Whereas a specific embodiment is herein shown and described, variations are possible. Accordingly, the invention should be understood to be limited only by the accompanying claims, purposively construed.
