Description

The present invention relates to an improved tile installation tool. Background Tiles are thin, tessellatable coverings made of material such as porcelain, ceramic, stone, metal, baked clay, or glass. Surfaces are tiled, meaning to cover with tile, giving a protective outer layer. Building walls, both internal and external are commonly tiled. The process of tiling involves the placing adhesive on a surface and placing tiles onto that adhesive. The adhesives take time to set. When tiles are being placed over an overhang, for example a door or window, before the tiles are fully set the tiles are at risk of falling or becoming unaligned, which is undesirable. Holding the tile in place manually while the adhesive sets is burdensome and wastes large amounts of time. One employed solution is to measure and cut wooden supports, using wooden beams as horizonal and vertical members, wedged in place, these have to be recut for every use and are at high risk falling, due to external forces. In particular, improvements in tile manufacture have led to tiles being made which are relatively large and consequently heavy and therefore manually placing and retaining in place tiles during the tiling process is not only physically cumbersome but also requires considerable skill and accuracy. This is particularly so for ceramic tile which have high density, low porosity and are particularly dangerous, sharp when smashed such as from falling. Therefore, an apparatus which provides one or more of making the task less cumbersome, making it more accurate and deskilling the task is advantageous. These are objectives which can be usefully addressed. The present invention The present invention in its various aspects is as set out in the appended claims. The present invention is a wall tile installation tool for supporting tiles during installation on vertical surfaces; the tool comprising; orientation being that in normal use: an elongate stanchion attached to; an upper bar; the upper bar carrying a plurality of tile supports configured to engage with an edge of a tile and slidable along at least a portion of the bar. An advantage of this is that the supports can be moved to different positions to enable the relevant support for individual tiles to be accomplished. Preferably this allows for one or more tile supports to be used per tile. This further allows each tile to be securely supported. This is particularly advantageous in light of the increased use of non-porous ceramic tiles particularly porcelain tiles, particularly large porcelain tiles. Large porcelain tiles are heavy such that falling tiles are particularly hazardous. Porcelain is brittle and prone to braking if dropped. Porcelain when broken is dangerous, the broken edges being sharp. Non-porous ceramic tiles can be vulnerable to moving undesirably while the adhesive is setting. The adhesives used for attaching non-porous tiles can have long setting times, too long for the tiler to be expected to hold the tile in place for the entirety of the setting time. This is further advantageous as it frees the tiler have tiles held in place while having both hands free, allowing the tiler to perform other tasks while the adhesive sets. Preferably the installation tool is such that the tile supports comprise lateral extensions configured to engage said tile edge(s). An advantage of this is it allows the tool to sit within a cavity, such as a window opening in the supports protrude so as to allow tiles on a wall to be supported at their edge. Preferably the installation tool is such that the lateral extensions are in the form of hooks being indents within the lateral extension to accommodate the edge and relevant comers of tile for the purposes of preventing lateral movement of the tile. An advantage is that this permits the tiles be more securely supported both vertically and laterally. Preferably the tool comprises a plurality of sets of tile supports for accommodating different tile thicknesses, each set being laterally slidable on and off the upper arm so as to enable replacement of one set by another. This provides greater versatility in the tool particularly so that when the tile supports are configured to a particular tile thickness they may be swapped out to the correct form of support for a particular task. Preferably the installation tool is such that the tile supports are made of a smooth surfaced plastics material, preferably selected from polyethylene or polypropylene. This reduces the adhesion of tile adhesive to the supports so that they may be readily disengaged from tiles if there is overspill of the adhesive during application and similarly upon cleaning of the tool after use the adhesive is more readily removed. This works in conjunction with the support being adjustable immovable and that the ability to move the must be maintained for the tool to be effective in multiple uses. Preferably the tool is such that the stanchion, as at an end remote from the end connected to the arm length comprises adjustment feature for adjusting the effective length of the stanchion. An advantage is that this enables the length of the stanchion to be readily adjusted to different size openings. Preferably the tool is such that the length adjustment feature is a tube in tube arrangement such that the stanchion may be telescoped to different lengths. This more readily allows adjustment of the length beyond that which is effective with a simple screw extension. Preferably the tool within the portion of the tube which is not attached to the arm being replaceable by in the tool being supplied with a plurality of different lengths of tube. This allows radically different sizes of opening to be accommodated. Preferably the tool is such that the tube in tube telescopic arrangement is configured so that, in use, the lower tube nests within the upper tube. This allows that any adhesive which falls on the stanchion does not get pushed in or otherwise enter the gap between the tubes and serves to solidify them together, the overhang meaning is less likely to be contamination particularly at the joint where one tube enters the other. This facilitates cleaning and gives more effective lifetime of the product. Preferably the tool is such that the length adjustment feature is securable in different positions by means of a screw fastening. This enables fine adjustment of the length of the stanchion readily accommodate different window sizes. Preferably the tool is such that the length adjustment feature comprises a manually actuated ratchet mechanism to advance a rod nested within the upper part of the stanchion to extend the length of the stanchion, such as in the manner of mechanism used for a mastic gun. This allows rapid one-handed adjustment of the length of the tool so it may be placed whilst being studied by the other hand of a single installer. Preferably the tool is such that the arm has a rectangular cross-section. This enables the tile supports to be readily maintained extending laterally from the arm as the tile supports are not readily able to rotate due to the rectangular crosssection of the arm corresponding to the rectangular opening in the tile supports. Preferably the tool is such that the arm is slidably attached to the stanchion such that the stanchion may be moved along the length of the arm much in the manner of the tile supports. This allows the position of the stanchion to be adjusted so that if a support for the base of the stanchion is not readily available in a first position and it may be adjusted to be supported in a second position. Preferably the tool is such that the overall tool is T shapes wherein the stanchion provides the vertical of the T and the arm the lateral of the T. This provides a balanced arrangement so that the tool is readily held up right such as by one hand of a user allowing the other to be free to align the tile. The tool may preferably be fixed in this format to be more secure for repeated use. Alternatively, the tool is such that the overall tool is L shaped wherein the stanchion provides the vertical of the L and the arm the lateral of the L, the tool being configured to be normally used as an inverted L. This enables the tool to be used where a central support is not available, such as in an overhang. The tool may preferably be fixed in this format to be more secure for repeated use. Preferably the tool, and in particular the arm and the stanchion are constructed of steel. This is the advantage that the weight of the tool is substantially greater than if constructed of other materials and since the weight of the tool is supported by the stanchion the overall greater mass of the tool means that there is greater inertia so that an accidental movement, such as by the arm of an installer, does not result in drastic movement of the tool and thus less likely to disturb tiles being supported. This is particularly useful when, for example apertures are being drilled proximate to the tool with tiles being supported as the effect of vibration is much dampened due to the inertia from the weight. Preferably the weight of the tool is greater than 2 kg. This has been found to give sufficient inertia to obviate the effects of vibration from nearby drilling actions, such as to provide apertures and a wall whilst still enabling effective manual handling single handed as above. Preferably the tool wherein a spirit level is affixed to a side face of the tool, referee with the arm of the tool, more preferably on a right-hand extension of the arm of the tool relative to the stanchion. This reduces the complexity of use of the tool in that the operator can readily vertically align the tool with one hand, secure it with the other hand, such as in the terms of the length of the stanchion or the lateral adjustment of the tile supports whilst maintaining a correct orientation relative to the vertical. This enables a compact operation to be achieved by a single operator. Preferably the tool is such that the stanchion has an extension upward from the end of the stanchion interfacing with the arm and that upward extension is considered configured to be of adjustable length. This enables the degree of overhang, vertically to an aperture of tiles, to be readily adjusted without having to replace the tile supports. Preferably the tool is further comprising an inbuilt laser pointer configured in normal use to point vertically or horizontally. This enables the support tool to be placed in the middle of a large opening and its positioning to be accurately determined relative to an edge of that opening. Preferably the tool is such that the arm comprises adjustment feature for adjusting the effective length of the arm. An advantage of this is that it enables the length of the arm to be readily adjusted to different size openings. Preferably the tool is such that the length adjustment feature is a tube in tube arrangement such that the stanchion may be telescoped to different lengths. This is a convenient mechanism to adjust the length of the arm and is preferably accompanied by at least a portion of the inner telescoped portion of the arm having lateral dimensions corresponding to the outer telescoped portion of the arm along at least a portion of its length. This enables the tile supports to be utilised and the telescoped portion. Preferably the invention is provided as a kit of parts. Preferably the kit of parts constituting the tool of the present invention in the form of a conjoined stanchion and arm together with a plurality of tile supports. Preferably the kit of parts constituting the tool of the present invention in the form of a conjoined stanchion and arm together with a plurality of stanchion extensions of different lengths.

An advantage is the kit of parts enables the adaptation of size to be readily accommodated, for different end use situations. Preferably the tool is further comprising a swivelling foot with a plastic end cap. The plastic foot will not dent or damage the surface that the foot is placed on. Preferably this foot can rotate slightly to adjust to any surface variation. This is particularly useful for uneven surfaces. If tiles have already been placed on the lower surface of a window that is directly below the overhanging recess, it is common for these tiles to not have surfaces perpendicular to the direction of gravity, instead being angled as to direct the flow of water off the tiled surface. The tool does not require that these tiles were placed parallel to the tiles that are to be attached to the upper surface. This is also advantageous to prevent damaging or denting surfaces thus avoiding creating undesirable blemishes on the window frame’s surface. Optionally the tool further comprises top foot suitable to in use to press against a lintel i.e. an upper bounding surface. This advantageously allows the tool to be more firmly constrained into a window frame or door frame, greater protecting against the tool falling over. Preferably the tool is further comprising Sliding Lips comprising folded and welded sheet metal. These components have a lip on the top to help prevent tiles from slipping out of place. The placement of the lips can be adjusted to hold up each tile as is preferable for the given job, for comparatively smaller tiles each tile may be best held in position by a single lip centrally placed on each tile, alternatively larger tiles may be held up by two or more lips placed uniformly along the tile. Preferably this also allows the frame to be perfectly vertical. They can be slid along the extending arm and can also be removed if needed. Lip elements can be added and subtracted from the tool in line with the requirements of a given tile set. Larger and smaller lip elements can be swapped in and out as required. Preferably the tool comprises screw clamps. Preferably wing screw clamps. Advantageously these allows the user to fix the sliding arms. Clamping the arms in place protects against the arms moving if accidently nudged. If the tool is used on multiple windows of the same size, then the clamped arms can be left in place with only the feet adjusted in and out. The Main frame is a welded frame. The Main frame is capable of holding large tiles without bending or braking. Preferably the main frame is made of metal. Preferably the main frame of the invention is constructed from steel. This gives the strength that the frame requires. Preferably the steel is powder coated. Preferably the powder coat has a blue finish. Alternatively, the frame is made out of aluminium, the tool being lighter so a larger tool can be carried and handled by the tiler. Preferably a customised black metal badge adorns the side of the frame. This is suitable for the display of information. The information may include instructions for use or branding. This allows for front and back faces of the tool to be distinguished. Preferably a spirit level bubble is placed in the framing. Preferably the spirit level bubble is in a cylinder vial embedded flush in an aperture in the framing. Allowing the user to ensure tiles are level and square with the wall / window. The spirit level bubble is attached as to show the level of the tiles held up by the tool. Preferably the spirt level bubble can be replaced. This is particularly useful if the bubble brakes. Preferably there is more than one spirit bubble vial each with spirit level bubble. Preferably using the spirit level bubble, the tool can be placed upright in both the axis of the bottom of the tiles that are supported and the axis facing out of the plain of the window. Preferably the tool suitable for multiple different window sizes. The tool can be extended / collapsed to fit the most common sized windows. This allows the same tool to be used for larger and smaller windows, and adjusted on the job. For even larger windows multiple copies or the tool can be used in conjunction. Preferably the size can be adjusted from: 850 x 667mm up to 1120mm x 1260mm, height x width. Different embodiments of the invention can be different sizes for different common and uncommon ranges of window sizes. Preferably the tool has an offset. The lips are pronounced from the frame, so that the tile can sit flush against the wall. To further achieve this, the feet are set backwards (towards the window). This means the tool's feet have full contact with the inside walls of the window and are not too close to the edge. The additional contact creates a stronger hold. Preferably the use of the tool can be described with the following procedure: Place the tool under the overhang in question for example inside a window ledge, extend arms the of the tool to fill the window space, tighten the feet out to fix the jack in place, adjust the lips by sliding to positions under the intended tiles, apply adhesive to the wall, place tiles such that they are against the wall and supported in place the lip, wait for adhesive to set, loosen feet, remove tile jack, retract arms for storage. Preferably the tool is suitable to allow tiles above the overhang to be attached prior to or subsequent to tiles below the overhang. Preferably the use of the tool is easy to learn and teach. The invention can preferably be disassembled, allowing for storage, transport, cleaning, interchanging of parts including replacement of damaged parts, upgrading of the tool for example to have longer arms or additional sliding lips. The invention can preferably be reassembled from these composite parts Preferably, the arms and legs can be extended in a similar manner as the extension of one-handed bar clamp with quick-release trigger.
