Definitions

  • the present application pertains to the field of tiles and tiling. More particularly, the present application relates to modular tile and block kits.
  • Interlocking tiles are commonly used in landscaping, flooring, building construction, art work or for puzzles and games.
  • individual tiles are placed adjacent to each other and are interconnected to form a larger tile assembly.
  • the connection between individual tiles can range from a simple abutment of adjacent sides or edges of the tiles, or can include interconnecting a portion of one tile with a complementary portion of an adjacent tile. This interconnection can be integral to the individual tiles, or can be facilitated by an external interconnecting means.
  • Puzzles are popular recreational diversions which employ interlocking pieces. Puzzles offer not only entertainment to the user, but can also help develop and fine tune motor skills and spatial reasoning, particularly in children. There are a number of types of puzzles, each offering a particular level of difficulty based on, for example, the size and number of puzzle pieces, diversity of colours and patterns appearing on the pieces, and the means of connecting different pieces within a puzzle assembly, including the complexity of the interconnecting means.
  • puzzle pieces can be arranged in an assembly to form one or more completed images or tangible components that can provide other uses for the puzzle. If a completed image is assembled, it can be used as a display (such as a photograph or work of art), a reading tool (such as shapes, text or colours), or can contain tactile features that can be used in connection with other toys, puzzles or games.
  • a puzzle can be assembled to form the image of a patchwork of "roads", presented in an urban landscape, often with buildings, trees or other landmarks. Children use miniature model cars to simulate driving on the roads. Thus, puzzles of this sort can offer hours of entertainment beyond the initial assembly of the puzzle.
  • Typical puzzles contain pieces having "male” and “female” portions thereon.
  • the "male” portion - such as a tab - extends outward from the piece to engage with a "female” portion - such as a slot - thereby forming a connection between the two pieces.
  • the access between male and female can be within adjacent sides, or beneath a surface of one or both of the pieces, such as in cases where the female portion is recessed and hidden from view. Because of the fixed nature of the male and female portions, a successful connection between adjacent pieces is dependent on the spatial alignment and orientation of the portions with each other, as well as a proper fit between the male and female portions. Failure to meet these criteria can lead to an improper and unstable connection, and an unattractive assembly.
  • An object of the present invention is to provide a modular tile and block kit.
  • a modular tile assembly kit comprising a plurality of tiles, and one or more connectors configured to attach to one or more of said plurality of tiles for connecting with another one or more of said plurality of tiles.
  • the kit can further comprise one or more structures, such as blocks, which are configured to receive said one or more connectors and connectable with one or more of said plurality of tiles or with one or more additional structures.
  • a tile for use in the modular tile assembly kit comprising a channel within a surface of the tile for receiving a connector, the connector being adapted for connecting the tile with an adjacent tile.
  • a connector for the modular tile assembly kit comprising: a bar portion having first and second ends; a first arm at the first end of the bar and generally perpendicular to the bar in a plane, the first arm having first and second portions; a second arm at the second end of the bar and being generally perpendicular to the bar in said plane, the second arm having first and second portions; the bar, first arm and second arms having a coplanar surface, wherein the first end of the bar is positionable within a channel on a surface of the tile extending inwardly from an edge of the tile, and the first arm is positionable within a cross channel generally perpendicular to said channel.
  • the second end of the bar is positionable within a corresponding channel on a surface of an adjacent tile extending inwardly from an edge of the adjacent tile, and the second arm is positionable within a corresponding cross channel on the surface of the adjacent tile and generally perpendicular to said corresponding channel.
  • the present invention provides a tile assembly with increased flexibility and utility.
  • the versatility of the connector permits its use with any suitable tiles having compatible channels thereon.
  • the connector as described herein can be made universally compatible with tiles having a complementary channel arrangement. The compatibility allows for locking of adjacent tiles by the connector, thus reducing shifting or other disorientation of the tiles within the tile assembly.
  • the connector is ideally placed within the channels on the bottom side of tiles from a bottom-to-top direction, rather than in an edge-to-edge direction.
  • adjacent tiles can be dropped and added (and, by corollary, lifted and removed) from the tile assembly. This is particularly useful for connecting adjacent tiles in a section of a tile assembly where movement within a confined space is compromised (such as against a wall or other structure abutting an exterior edge of the assembly).
  • Individual tiles do not require a "male" portion which protrude out from an edge of the tile, thereby allowing the edges of the tiles at the perimeter of the tile assembly to be flush, rendering the tile assembly more aesthetically pleasing.
  • Figure 1 provides a view of a top surface of an exemplary tile as described herein;
  • Figure 2 provides a view of a bottom surface of an exemplary tile as described herein;
  • Figure 3 shows a view of a bottom surface of another exemplary tile as described herein;
  • Figure 4 shows a connector as described herein

  • Figure 13 shows an exemplary assembly of stacked tiles and structures that can be made with the tiles of Fig. 12A and connector of Fig. 12B.
  • Figure 14 shows an exemplary tile assembly grid as viewed from the bottom surface of adjacent connected tiles.
  • a "tile” is a member having at least one substantially planar surface.
  • the tiles can have any number of edges, such as one, two, three, four or more edges, and can be any thickness, shape or size.
  • substantially planar it is intended to include tiles having one or more flat surfaces, or having one or more surfaces comprising recesses or channels (as described below), but ideally having at least one surface which is parallel to a surface on which the tile is placed (such as a floor, an adjacent tile, or the like).
  • the tiles as described herein are used together, either separately or conjoined, to form a modular tile assembly. Tiles can also be circular or have one or more curved edges.
  • a "structure” is a member which can be used with one or more tiles. Structures are placed on top, below, and/or beside adjacent tiles, and can be connected therewith, or with other structures. A structure may or may not have at least one planar surface. Suitable structures can include blocks to represent different features of a modular tile assembly, including buildings, people, flora (such as trees or the like), or any member as desired by the user.
  • a "modular tile assembly” as described herein is an assembly comprising a number of components but, ideally, comprises a plurality of interconnecting tiles and/or structures.
  • Exemplary tiles which can be used in accordance with the present assembly are shown in Figs. 1 and 2.
  • a tile 10 is four-sided, such as square or rectangular shaped.
  • a typical tile has a top surface 10, a bottom surface 14, and one or more edges 16.
  • Tiles can be made of any durable material. Examples include wood (or wood-like material, such as particle board or synthetic wood), plastic (including polymer- based plastics, including poly(methyl methacrylate) and the like), cardboard, gypsum, glass or metal.
  • the tiles can be of any desired thickness and flexibility.
  • a top surface 12 of a tile is substantially planar, though any desired surface landscape may be envisioned. This can help produce a more attractive assembly surface as well as promoting a more entertaining experience for the user. To achieve this overall smooth surface, the tiles should ideally be substantially flush when the edges of adjacent tiles abut each other.
  • the top surface can be devoid of any colour or design; however, either surface can be covered with a protective material, such as stain-resistant compound or the like.
  • the top surface can be ornamented with a decoration or image.
  • Tiles need not be four-sided; indeed, tiles can be circular or of another shape such as a triangle, "star"-shape, pentagon, hexagon, etc.
  • the shapes of the tiles need not be regular and can be oblong (i.e., a form being elongated in one direction), including oval or irregularly shaped tiles.
  • top surface of a tile is displayed upward to the user while the bottom surface is faced downward toward the surface on which the tile assembly is constructed.
  • Adjacent tiles interconnect via one or more of the edges of the respective tiles. Any or all of the edges of a tile can connect with any or all of the edges of an adjacent tile.
  • a tile for use in the modular assembly as described herein has one or more recesses on the bottom surface for permitting connection with an adjacent tile.
  • Recesses are typically in the form of a channel cut out of a bottom surface.
  • the channels can be any depth but typically do not extend through to the top surface of the tile.
  • An exemplary tile displaying the channels on the bottom surface of a tile is shown in Figure 2.
  • An edge channel (such as edge channels 18, 21 and 22) extends from an edge (such as edges 16B, 16A and 16C, respectively) of the tile inward generally perpendicularly thereto.
  • An edge channel, such as edge channel 18 can extend beyond a cross channel 20 (continuing as cross channel 23), or can terminate at a cross channel (such as edge channel 26 which terminates at cross channel 27).
  • a cross channel 20 forms a "T" or cross intersection with the edge channel 18.
  • the cross channel 20 can extend all or part of a length parallel to one edge 16.
  • edge channel 18 terminates at cross channel 20.
  • Cross channel 20 extends from edge channel 22 on edge 16C to edge channel 21 on opposite edge 16A of the tile.
  • cross channel 20 can itself be an intersecting channel to one or more other cross channels, such as cross channels 23 and 25, for example.
  • Edge channel 26 is framed by edge portions 52 and 54, and cross channel 20 is framed by bottom surface 14, and edge portions 52 and 54. Edge portions 52 and 54 are generally flush with bottom surface 14 to ensure that the tile maintains stability when placed on a surface, such as a floor or table.
  • Figure 3 shows another embodiment of a bottom surface of a tile.
  • the tile comprises four edge channels 30 which terminate at four cross channels 32, which together form a square around the bottom surface of the tile.
  • a tile can have any number of edge channels.
  • a tile can have any number of edges and does not need to be square or rectangular. Therefore, depending on the number of edges of the tile, any number of the edges can have one or more (or no) edge channels.
  • edge channels can be spaced apart at any desired location. In other words, the edge channels and corresponding cross channels need not be regularly spaced or distributed on a tile. Indeed, a tile having a plurality of edges can have one or more of these edges with or without an edge channel extending therefrom.
  • the channels permit the placement of connectors therein, such as connector 40 as best shown in Fig. 4.
  • the connector 40 is ideally of a durable material, such as wood, metal or plastic.
  • the connector can also be sufficiently flexible to permit a twisting or rotating action thereof.
  • connector 40 is a member having the shape of an ⁇ " or the like and is generally of three components: arms 42 and 44, and bar 46 which connects the arms.
  • the connector 40 can be of any dimension, and can include arms or a bar of any desired length, thickness or proportion.
  • the bar 46 of the connector 40 is longer than either of the arms 42, 44.
  • the connector can have arms with rounded edges rather than sharp, square edges, thus rendering the connectors less of a safety hazard for younger users.
  • Fig. 5 shows one example of a connector inserted within channels within the bottom surface of a tile.
  • Tile 50 has a pattern of channels similar to that shown in Fig. 2.
  • Connector 40 is inserted into the channels of the tile 50.
  • Arm 44 comprises first arm end 56 and second arm end 58, which extend on either side of bar 46.
  • arm 44 is placed into cross channel 20, and bar 46 is inserted into edge channel 26.
  • Placement of the connector into the channels can be achieved by any desired means, such as "dropping" the connector into the channels, by placing the arm into the cross channel first, or by placing the bar into edge channel first. Placement of the connector terminates when the connector fits snugly within the channels.
  • the cross channel and edge channel should be sufficiently deep so that a connector will fit within the channels such that the arms and/or bar of the connector do not protrude beyond the bottom surface 14 of the tile, maintaining the connector substantially flush with the bottom surface of the tile.
  • the connector is firmly placed is when the bottom surface of the connector (i.e., the surface not in contact with the channel) is substantially flush with the bottom surface 14 of the tile, and/or with the edge portions 52 and 54.
  • a portion of the bar 46 and a second arm 42 of connector 46 will extend beyond one edge 16 of the tile 50. This portion of the bar and second arm are now in position to connect to an adjacent tile.
  • FIG. 5 A Another view of the connector attached to a tile is shown in Fig. 5 A
  • Connectors can fit in any compatible channels that are wide enough to receive a connector.
  • the arms 42, 44 and bar 46 of a connector can be just wide enough or narrower than a cross channel and edge channel, respectively.
  • the connector can be of any particular shape or size to permit connection of adjacent tiles.
  • the bar 46 can be longer to permit multiple tiles or structures to be placed adjacent to each other using only one connector.
  • connectors can include multiple bars and/or multiple arms to permit multiple connections of adjacent tiles and/or structures.
  • Connectors can also be different shapes, not exclusively ⁇ " shaped. For example, they can be "S", ' ⁇ " or "T” shaped, providing at least one bar to fit within the edge channel.
  • any number of connectors may be used to connect any number of tiles to form the modular tile assembly as described herein.
  • This flexibility permits modular tile assemblies of any desired shape or size to be formed.
  • the arms of a connector can be oriented within adjacent edge channels, leaving the bar and lower portions of the arms exposed rather than inserted within the edge channel.
  • the connector will be inserted with the arms in the cross channel and a portion of the bar within the edge channel, as this arrangement provides greater stability for "locking" the connector into place within the channels of the tile. This greater stability also reduces any shifting of tiles that may occur if the tile assembly is jostled or otherwise disoriented.
  • Connectors with longer bars can be used with tiles having longer edge channels with corresponding cross channels positioned further from the side of the tile, i.e., further towards the interior of the bottom surface of the tile. This particular arrangement may be desirable to enhance stability of the tile assembly.
  • Fig. 6 shows a connection between adjacent tiles viewed from the bottom. Bottom surfaces 14, 70 of two adjacent tiles 50 and 60 are shown.
  • the arm 44 and bar 46 of connector 60 are placed within the channels of tile 50 as described above. Arm 42 and a portion of bar 46 are positioned outside of tile 50, such that arm 42 and the portion of bar 46 jut outward from edge 16.
  • arm 42 is inserted into cross channel 32 and the portion of bar 46 is inserted into edge channel 30 of tile 60.
  • the connector 46 can then be pressed within the channels (either by pressing on the connector directly, or by pressing the top surface of the tile) such that the connector 40 is substantially flush with the bottom surface 70 of the tile 60.
  • connector 40 is complete when the surface of the connector is substantially also flush with edge portions 72 and 74 of tile 60.
  • the connector should be substantially flush with the bottom surface to maintain a smooth surface without any protruding portions which could impair the stability of the tile assembly when placed on a surface, such as a table or floor.
  • Like-shaped tiles need not connect to like-shaped tiles.
  • a square tile need not connect with another square tile.
  • an edge 65 at the long end of a rectangular tile 61 can connect with a corresponding portion of an edge 16 of a square tile 60.
  • the connector can be placed in the channels by inserting arms 42 and 44 into multiple edge channels, such as adjacent edge channels 18 and 26.
  • portions of the arms extending beyond the side of the tile can be inserted into edge channels of an adjacent tile.
  • the connector is firmly held within the channels to ensure that the connector does not readily become disengaged during use of the tile assembly.
  • insertion of the connector into the channels "locks" the connector in place. This is achieved because the arm(s) of the connector are held in place by the walls of the cross channel, which provide resistance against an edge of the connector arm(s).
