ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to tiles. More specifically, the present invention is concerned with a tile tracing apparatus and with a tile tracing method to reproduce, on a tile, lines representative of the layout of the floor where the tile is to be installed.
BACKGROUND OF THE INVENTION
Persons installing tiles on a floor are regularly challenged with the cutting of particular tiles to conform to the floor layout where the particular tile has to be installed.
The commonly accepted method used for cutting such tiles consists in taking manual measurements of the floor layout in the area where the tile is to be installed. These measurements are then transferred to a conventional tile, which is thus ready to be cut.
Of course, the method used to cut the tile varies with the type of tile used. For example, knives may be used to cut vinyl tiles while specially designed cutting assemblies are used to cut through encaustic and ceramic tiles.
The precision required to cut tiles is usually not of great importance since a quarter-round molding is usually installed over the tiles at the floor to wall joint. However, the manual measurement and the transfer of these measurements onto a tile often lead to the waste of a tile which has been improperly cut, which increases the overall cost of the floor covering.
Furthermore, the time required to take the measurements and to transfer these measurements onto the tile is usually quite long, which is another drawback of the manual measurement taking method.
SUMMARY OF THE INVENTION
An object of the present invention is therefore to provide a tile marking apparatus and a method therefor.
Another object of the invention is to provide a tile marking apparatus that is designed to transfer, directly onto a tile, the layout of the floor where the tile is to be installed, for most floor layouts.
In accordance with the invention, these objects are achieved with a tile tracing apparatus comprising:
a frame assembly;
a longitudinally movable assembly mounted to the frame assembly; and
a laterally movable marking assembly mounted to the longitudinally movable assembly including a movable carriage and a contour following rod having a proximate end provided with a pen attachment device, to which a pen may be mounted, and a distal end provided with a contour following tip, said contour following rod being telescopically mounted to said movable carriage.
Other objects, advantages and features of the present invention will become more apparent upon reading of the following non-restrictive description of preferred embodiments thereof, given by way of example only with reference to the accompanying drawings.
