DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

The inventive concept relates to a modular shelving and storage system. A plurality of pieces are provided, each piece can interconnect into other of the plurality pieces. A kit can be provided of a large quantity of the different pieces so a user can construct a shelve utilizing different configurations of the pieces.

There are five main types of pieces described herein, a first piece, a second piece, a third piece, a fourth piece, and a fifth piece. Each of the types of pieces would typically be identical to the other pieces of the same type. All of the pieces can be made from wood, although other materials can be used as well such as metal, plastic (typically hard), laminate, bamboo, etc. The material used should typically be smooth.

The pieces can be connected to one another by sliding the pieces into each other without the need for any type of adhesives (e.g., glue, etc.) or permanent connectors (e.g., nails, etc.) Note that optionally, adhesives can still be used (e.g., glue, nails, etc.) if the user wants to create a permanent structure, but such adhesives are not required. The pieces are constructed and configured such that the channel(s) of one piece will slide into/through a corresponding channel(s) of another piece, and ridges of one piece will slide into/through corresponding grooves of another piece.

The pieces can be supplied in kit form, for example any number of each of the pieces can be provided in a large container (e.g., 20-100 (or any other number) pieces of each type).

FIG. 1A is a diagonal top view of a first piece, according to an embodiment. FIG. 1B is an enlarged drawing of the circled portion in FIG. 1A, according to an embodiment.

The first piece (piece one) has only four tines 100 (first tine), 101 (second tine), 102 (third tine), 103 (fourth tine) all on the rear side. The first piece is symmetrical on the left/right side (in other words the left side and right side are mirror images of each other). Between (or adjacent) to each tine are channels 110, 111, 112, 113, all located on the rear side (with no channels on the front side). A middle section 150 is between the second channel 111 and the third channel 112. Note that the middle section 150 is larger than all of the tines and all of the channels. On the left side and right side of each channel are ridges. For example, channel 112 has left ride 120 and right ridge 121, channel 113 has left ridge 122 and right ridge 123. Extending past each channel are grooves 130, 131, 132, 133. The ridges are all configured to slide through grooves on another piece (whether the same type or different piece). Note that there are pairs of opposing grooves, for example a first pair of grooves 130 extends past the first channel 110, with the first pair of grooves 130 comprising a groove being on the top side and an opposing groove being on the bottom side (not visible in FIG. 1A but exists opposite the groove 130 shown). In this manner a left ridge (or right ridge) in a channel of another piece would slide into the top groove and the opposite right ridge (or left ridge) of the same channel of the another piece would slide into the bottom groove, thereby providing stability to the connection. Each of the channels 110, 111, 112, 113 would have a corresponding pair of grooves that extends past the channel. The grooves and the left/right ridges (of the other pieces) are all configured (with the proper locations, dimensions, etc.) to cooperate and fit/slide together. Typically when one piece is connected to another piece the pieces are held perpendicular to each other so that the channels can slide into each other and both pairs of grooves would slide along each pair of ridges of the other piece. Two holes are present a front hole 141 and a rear hole 140 can be used to insert a backing (discussed elsewhere).

All channels (in all pieces) would run from an end (front or rear) of the piece to the middle (between the front and rear) of the piece (or near the middle such as within an inch from the middle). All channels would also be parallel to all other channels in the same piece. All tines would also be parallel to all other tines in the same piece. All pieces can be rectangular (note that a square is considered a rectangle).

Note that the top half and bottom half of the first piece (and all other pieces) are symmetrical. Also note that if all parts of the first piece (and all other pieces) are not clearly shown in the drawings, these parts can all be discerned by the shown parts because the structure of the same parts of each piece are identical. For example, in FIG. 1B, the right ridge 123 of the channel 113 is not entirely shown, but the right ridge 123 of the channel 113 would have the same structure as all other ridges (in the first piece and other pieces). All tines and channels (and other parts) on all pieces would have identical dimensions (length, width, etc.) Thus, from the figures, the structure of each part can easily be discerned even if not shown in its entirety. The structure of all pieces are consistent with each other (a piece's own other parts as well as the parts of other pieces). The structure of the ridges (in all pieces) are such that they are configured to fit tightly but slide through the grooves of all other pieces that those ridges can contact. The channels of all pieces are also configured to fit and slide through channels of all other pieces until they meet at the end of each channel (at or near the middle of each piece). In other words, when each piece is slided into another piece, they will meet at the middle of each piece. The ridges will slide through the corresponding grooves of the other piece This universal structure/configuration which is common to all of the pieces allows each piece to fit (slide) into any other of the pieces. All piece types can even slide into another piece of the same type.

Note that all of the other pieces will use the same descriptive terms (e.g., tines, channels, middle section, etc.) and will have the same general structure (middle section in the middle between channels, etc.) For example, all channels in all pieces would typically have a pair of grooves (on top and bottom) extending past the channel so that the left/right ridges of a connecting piece would slide through the grooves. Unless otherwise noted, the other drawings of the other pieces will show/use the same orientation as the first piece is drawn.

Because all pieces have compatible structures, dimensions, dimensions of parts, etc., a user can create customized structures by sliding a plurality of pieces together into other pieces thereby creating a stable interlocking structure. There is no limit to the number of pieces that can be joined together. As such, custom shelving (and other utilitarian structures) can be created which can fit particular desired dimensions.

FIG. 1C is a bottom view of the first piece, according to an embodiment.

The bottom half of each piece is identical to top half.

FIG. 1D is a rear view of the first piece, according to an embodiment.

The left and right ridges of each channel are shown, as well as the upper and lower groove behind each channel. Note that the middle section 150 is larger (in the horizontal axis/direction shown in FIG. 1D) than the size (in the same horizontal axis/direction shown in FIG. 1D) of each of the tines 100, 101, 102, 103, and the middle section 150 is larger (in the horizontal axis/direction shown in FIG. 1D) than the size (in the same horizontal axis/direction shown in FIG. 1D) of each of the channels 110, 111, 112, 113.

FIG. 1E is a front view of the first piece, according to an embodiment.

The upper and lower grooves of in front of each channel are shown.

Note that in FIGS. 2A, 2B, 2C, 2D, 2E, 3A, 3B, 3C, 3D, 3E, 4A, 4B, 4C, 4D, 4E, 5A, 5B, 5C, 5D, 5E, 6A, 6B, 6C, the view nomenclature/references are identical to that shown/described in FIGS. 1A, 1B, 1C, 1D, 1E.

FIG. 2A is a diagonal top view of a second piece, according to an embodiment. FIG. 2B is an enlarged drawing of the circles portion of FIG. 2A, according to an embodiment.

The second piece (piece two) has four tines, 200 (first), 201 (second), 202 (third), 203 (fourth) two in front 201, 202, and two in the rear 200, 203. Piece two also has four channels, two in the front and two in the rear. As shown, the locations of the channels (from left to right) is as follows: rear, front, front, rear. A first channel is located between the first tine 200 and a middle section 250, a second channel is located between the second tine 201 and the middle section 250, a third channel is located between the third tine 202 and the middle section 250, and a fourth channel is located between the fourth tine 203 and the middle section 250. As all of the pieces, the upper (top) half of piece two is symmetrical (identical) to the lower (bottom) half. The left side of piece two is a mirror image of the right side. The middle section 250 is between the pair of channels on one end and the pair of channels on the opposite end. The front half of piece two is not a mirror image of the rear half of piece two.

As shown, the locations of the channels (from left to right) is as follows: front, rear, front, rear. As all of the pieces, the upper (top) half of piece four is symmetrical (identical) to the lower (bottom) half. The left side of piece four is not a mirror image of the right side. The front half of piece four is not a mirror image of the rear half of piece four.

FIG. 4C is a bottom view of the fourth piece, according to an embodiment. FIG. 4D is a front view of the fourth piece, according to an embodiment. FIG. 4E is a rear view of the fourth piece, according to an embodiment.

FIG. 5A is a diagonal top view of a fifth piece, according to an embodiment. FIG. 5B is an enlarged drawing of the circles portion of FIG. 5A, according to an embodiment.

The fifth piece (piece five) has four tines, 501 (first), 502 (second), 503 (third), 504 (fourth), one in front 504, and three in the rear 501, 502, 503. A middle section 550 is also present. Piece five also has four channels, one in the front and three in the rear. As shown, the locations of the channels (from left to right) is as follows: rear, rear, rear, front. A first channel is located between the first tine 501 and the second tine 502, a second channel is located between the second tine and the middle section 550, a third channel is located between the middle section 550 and the third tine 503, and a four channel is located between the middle section 550 and the fourth tine 504. As all of the pieces, the upper (top) half of piece five is symmetrical (identical) to the lower (bottom) half. The left side of piece five is not a mirror image of the right side.

FIG. 5C is a bottom view of the fifth piece, according to an embodiment. FIG. 5D is a front view of the fifth piece, according to an embodiment. FIG. 5E is a rear view of the fifth piece, according to an embodiment.

FIG. 6A is a bottom view of a wide first piece, according to an embodiment. The wide first piece has the same configuration/structure as the first piece but it is wider (as shown in FIGS. 6A, 6B, and 6C). FIG. 6B is a rear view of the wide first piece, according to an embodiment. FIG. 6C is a front view of the wide first piece, according to an embodiment. Any such width can be used.

All of the pieces shown in FIGS. 1-5 (standard pieces) can come in a wide version. The wide pieces would operate in the same manner as the standard pieces. Square boxes can be constructed with all for pieces of the same (compatible) dimensions. Alternatively, boxes can be constructed with wide pieces which oppose other matching wide pieces . A box can be formed with four compatible wide pieces. A box can also be formed with two wide pieces (opposing each other) and two standard (non-wide) pieces also opposing each other, thereby forming a non-square rectangle shape (instead of a square). Thus, boxes can be square but can also be non-square rectangular. Utilizing the wide pieces (as compared to the standard pieces) would provide additional storage space. A wide piece can interlock with a standard sized piece but you would need to have the pieces of matching width in opposition to each other to create a rectangular box. So, the 1-3-2-3 could be 1(wide)-3(standard)-2(wide)-3(standard). Although this can make a build-out (construction) a little more complicated, it actually provides for a dynamic solution with limited space. See FIG. 17 for an example of constructing rectangular and square boxes, according to an embodiment.

FIG. 7A is a bottom view of a first piece showing example dimensions, according to an embodiment. Note that the middle section of 8.4 inches is longer than the tine length of 0.5 inches and the channel length which is 0.5 inches (from FIG. 7B). Note that the middle section (8.4 inches) is also longer than half of the entire side length (12 inches) and hence takes up the majority of the length of the side. Note that any embodiment described or illustrated herein also covers all variations of that embodiment, for example if one part is longer (or shorter) than another part, then all embodiments with that one part being longer (or shorter) are included. Also note that while FIGS. 7A, 7B, and 7C refer to the first piece, since all of the pieces can have the same or similar structure/dimensions, the dimensions shown herein in FIGS. 7A, 7B, 7C can be applied to all parts and all pieces.

FIG. 7B is an enlarged view of the first piece from FIG. 7A showing example dimensions, according to an embodiment. FIG. 7C is a further enlarged view of the first piece from FIG. 7A showing example dimensions, according to an embodiment.

Note that the dimensions of all pieces can follow the same structure so that they can interlock with each other properly. Thus, while FIGS. 7A, 7B, and 7C show dimensions for the first piece, the dimensions for any of the other pieces would have the same structure (e.g., same groove lengths, same sized channels, etc.)

Furthermore, it is noted that the dimensions shown in FIGS. 7A, 7B, and 7C are merely examples and other dimensions can be used as well, so long as all of the parts being used together are consistent so that they can interlock with each other properly.

FIG. 8 is a drawing showing an assembly comprising the first piece and two third pieces, according to an embodiment.

Pieces that are illustrated are numbered with their respective type of piece. For example, the piece numbered with ‘1’ represents a first piece, the two planks numbered with ‘3’ represents the third piece, etc. All pieces numbered as such represent their corresponding piece type.

In the configuration shown in FIG. 8, two third pieces are held parallel to each other and a first piece is slide into the respective channels as shown. Once the three pieces are locked together, then the assembly can proceed to FIG. 9.

FIG. 9 is a drawing showing the assembly from FIG. 8 plus the second piece, according to an embodiment.

In FIG. 9 (follows from FIG. 8), a second piece is slid into the opposite ends of the third pieces as the first piece, as shown. This forms the box as shown in FIG. 10.

FIG. 10 is a drawing showing the assembly from FIG. 9 with all pieces fully interconnected with each other, according to an embodiment.

The four pieces (from FIG. 9), are pressed together tightly to form the box as shown which comprises two third pieces, a first piece, and a second piece.

FIG. 11 is a drawing showing two of the assemblies shown in FIG. 10 aligned for connection therebetween, according to an embodiment.

Two identical boxes that are shown in FIG. 10 are constructed side by side.

FIG. 12 is a drawing showing the two identical assemblies from FIG. 11 fully interconnected with each other, according to an embodiment.

The two boxes shown in FIG. 11 can be joined together as shown in FIG. 12 by sliding a lower corner of a first box (the one shown on the left of FIG. 11) between piece 2 and piece 3 through an upper corner of the second box (the one shown in the right of FIG. 11) between piece 1 and piece 3. A channel in piece 2 of the first box slides into a channel in piece 3 of the second box, and a channel in piece 3 of the first box slides into a channel in piece 1 of the second box, as shown in FIGS. 11-12.

A stable two box structure is formed. Many such boxes can be constructed and added to the configuration to form a custom, modular shelf which rests on the ground (and can also have one side pushed against a wall).

FIG. 13 is a drawing showing a configuration of multiple interconnected assemblies, according to an embodiment.

This is one example of a configuration which uses pieces 1-3 (first piece, second piece, third piece) to form the modular shelf.

FIG. 14 is a drawing showing another configuration of multiple interconnected assemblies, according to an embodiment. FIG. 14 shows another example of how pieces 1, 2, and 3 can be joined together to form a shelf configuration.

FIG. 15 is a drawing showing an assembly with an addition of a backing, according to an embodiment.

An optional backing 1500 (can be made of any material such as wood, cardboard, plastic, thick paper, etc.) has four tabs 1501 (only one such tab is numbered but there is a tab on each side of the backing 1500). Once a box is constructed, each of the four tabs can be pressed into a respective hole (as shown in FIG. 15), thereby forming a back (end) to the box. The backing would remain in place by virtue of the tabs 1501 having a snug fit with each respective hole in the pieces. In this manner, objects placed inside the box would not be pushed off the box in this direction since the backing is present to contain the objects. Of course, a backing would typically be only used on one side because if a backing was used on both sides of the box then there would be no way to insert objects inside the box. The backing 1500 would be easily inserted (placed) into the box (as shown) and also easily removed.

FIG. 16 is a drawing showing a further configuration of multiple interconnected assemblies, according to an embodiment.

The configuration shown in FIG. 16 utilizes pieces 1, 3, 4 and 5. Many such boxes can be formed and joined as shown in order to create a modular shelf.

The pieces described herein can be used to create custom shelfs of any dimensions (subject to the sizes of the pieces themselves), in other words, such shelves can be constructed as high and as wide as a user desires. The pieces can all come in the same color or they can come in different colors as well. Users can enjoy constructing their own custom shelves using the pieces described herein to best fit the dimensions of the room. Any pieces described herein can be joined/combined with any other pieces described herein in any fashion to create boxes and join the boxes together to create a modular shelf.

Note that the configuration of a single box can be stated using four numbers representing each of its sides in order. For example, the box illustrated in FIG. 10 can be represented as 1-3-2-3. Note that this can alternatively be stated as any of: 3-2-3-1; 2-3-1-3-; 3-1-3-2.

Note that the following combinations (sequences) can be used to create boxes which can smoothly interlock (easily connect with another box because it has an interlocking corner that has the two inner grooves in parallel so it could easily slide into another box also with parallel inner grooves) with at least two other boxes in at least two corners: 1-1-2-2; 1-1-3-3; 1-1-4-4; 1-1-5-5; 1-2-3-2; 1-2-5-5; 1-3-1-3; 1-3-3-2; 1-3-4-5; 1-3-5-4; 1-5-1-5; 2-2-3-3; 2-2-5-5; 2-3-2-3; 2-3-4-5; 2-3-5-4; 2-4-3-5; 2-4-5-3; 2-5-2-5; 2-5-3-4; 2-5-4-3; 3-3-4-4; 3-4-3-4.

Note that the following combinations (sequences) can be used to create boxes which can smoothly interlock (easily connect with another box (e.g., cube) because it has an interlocking corner that has the two inner grooves in parallel so it could easily slide into another box also with parallel inner grooves) with other boxes in all four corners: 1-2-1-2; 1-2-3-3; 1-3-2-3; 1-4-1-4; 1-4-3-5; 1-4-5-3; 1-5-2-5; 1-5-3-4; 1-5-4-3; 1-5-5-2; 3-3-3-3; 3-3-5-5; 3-5-3-5.

Note that the following combinations (sequences) can form boxes which do not smoothly interlock with any other boxes: 1-1-1-1; 2-2-2-2; 2-2-4-4, and 2-4-2-4. Note that as long as a combination (sequence) can create a box, it can technically interlock with any other box, but not necessarily “smoothly”. The difference being that a smooth interlocker has an interlocking corner that has the two inner grooves in parallel (so could easily slide into another also with parallel inner grooves) but if the inner grooves for a corner are in opposition (not “smooth”) then a user would have to build out the interlocking box with an opposition corner attached to that box first then build the box (or individual tiles) around that, so the simple sliding together functionality is gone and it's more complicated, but the boxes can still be interconnected).

Thus, a user could form any possible box type (whether stated herein or not) and join it with any other possible box type that would fit properly, and a lattice can be constructed by forming and adding more and more boxes to the structure. There is no limit to the size and ways in which boxes can be constructed and joined. A user only has to line up the channels in two different pieces and slide them together until they cannot be pressed into each other anymore. The box combinations stated above are examples but these are not intended to be an exhaustive list of the only boxes that can be formed using the pieces described herein.

FIG. 17 is a drawing showing combining rectangular and square boxes, according to an embodiment. As described herein, any combination/configuration of the pieces can be utilized which can form valid connections creating a stable structure, including combining wide and non-wide pieces (wide pieces having a different length from left to right than non-wide pieces while other dimensions of the pieces would remain the same) as shown in FIG. 17.

Note that all of the embodiments described and illustrated herein can be applied to both shelves (e.g., vertically stacked) as well as storage units (e.g., on the ground). For example any of the embodiments described and illustrated (or any others) can be constructed as one level resting on the ground (with or without the backing on the bottom which touches the ground), and the squares (boxes) therein can be used as storage (e.g., for storing pencils, tools, etc.). For example, see FIG. 15 but the box would be rotated such that the backing 1500 would be resting on the ground, table, etc. FIG. 16 (and any others) could be constructed horizontally (instead of vertically) which would mean FIG. 16 could be a top-down view (instead of a side view of the boxes were stacked vertically as shelves). If being used in this manner as a storage for pencils, then the size of the pieces can be smaller than as illustrated in FIGS. 7A, 7B, 7C, for example 25% (or any other scale) of the sizes shown. Thus, the inventive concept can be applied to vertically stacked shelves as well as a one level horizontal structure that rests on the ground.

The many features and advantages of the invention are apparent from the detailed specification and, thus, it is intended by the appended claims to cover all such features and advantages of the invention that fall within the true spirit and scope of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation illustrated and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
