BLOCK-BASED CONSTRUCTION SYSTEM
A set of building components is disclosed. The set includes a plurality of blocks and at least one connecting member for connecting and supporting a subset of the plurality of blocks in fixed relative position. Each of at least two of the blocks includes: a pair of parallel end faces, the end faces defining a block thickness therebetween, and a plurality of side faces extending between the end faces. Each of the at least two blocks defines three or more first holes extending between the end faces, wherein the first holes are arranged in orthogonal rows and columns and each pair of adjacent first holes extends in parallel spaced relation to each other. The at least one connecting member includes one or more rod portions that are sized to fit through the first holes of the blocks of the subset.
The present disclosure relates to construction systems and, in particular, to block-based construction sets for use in building toy and robot structures.
BACKGROUNDVarious block-based toy building systems rely on snap-fitting mechanisms. In such systems, each building block may include studs that project from one face and recesses formed on an opposite face such that a pair of such blocks may be assembled by inserting the studs of one block into the recesses of an adjacent block. For example, U.S. Pat. No. 3,005,282 describes toy building blocks that are adapted to be connected by means of projections extending from the faces of the blocks that are so arranged as to form clamping engagement with protruding portions of adjacent blocks when pairs of the blocks are assembled. Structures built using a snap-fitting mechanism must generally be built vertically and can be easily pulled apart. Such building systems are comprised primarily of rigid or semi-rigid materials (e.g. hard plastic or wood) and, more generally, may not adequately simulate the flexibility and structural diversity of soft tissues, metals, ceramics, elastic structures, complex composite materials, and deformable components, which are desirable in robotic systems, such as biologically-inspired robots.
Traditional toy building systems typically have either “sparse” or “dense” architecture styles, but not both. A “dense” architecture can refer to an architectural style of a structure that is tightly packed, characterized by building elements (e.g. blocks) that are assembled in such a way as to leave little or no empty space between them. Examples of a dense architecture may be found in structures built using Lego′ blocks and masonry bricks, as well as most forms of sculpture. A “sparse” architecture, on the other hand, can refer to a style of a structure which comprises building elements that have substantial spacing between them, and are therefore often characterized by the use of beams, joints, and sheets that connect the building elements. Various construction systems, such as those disclosed in U.S. Pat. No. 5,752,869 and U.S. Pat. No. 5,238,438, allow for primarily sparse constructions.
It would be desirable to provide a construction system that can facilitate building structures of both dense and sparse styles and employ an interlocking mechanism of construction, while representing a structural diversity that is appropriate for modern robotic systems.

In another aspect, the present disclosure describes a block-based structure. The structure includes a plurality of blocks, at least two of the blocks including: a pair of parallel end faces, the end faces defining a block thickness therebetween; and a plurality of side faces extending between the end faces. Each of the at least two blocks defines three or more first holes extending between the end faces, wherein the first holes are arranged in orthogonal rows and columns and each pair of adjacent first holes extends in parallel spaced relation to each other. The structure also includes at least one connecting member having one or more rod portions that are sized to fit through the first holes of the blocks, wherein the at least one connecting member is configured to connect and support the plurality of blocks in fixed relative position.
Other example embodiments of the present disclosure will be apparent to those of ordinary skill in the art from a review of the following detailed descriptions in conjunction with the drawings.
The construction system, or construction set, described in the present disclosure includes a plurality of blocks and connecting members for assembling the blocks into rigid or flexible structures. The construction set may also include strings and tapes for use in fixedly securing the blocks together. The blocks comprise solid geometric forms which can interlock to form three-dimensional mechanical structures. The blocks can be interlocked/connected to each other using one or more connecting members that comprise rod portions, or by using strings or tape to fasten the blocks together. For example, strings may be tied to, wrapped around, or threaded through holes defined in one or more blocks, and tape may be threaded in between adjacent blocks, wrapped around blocks, or be adhered to blocks. Blocks can be adhered to the same piece of tape to create hinge structures. The present construction system may be used to represent a variety of biological and mechanical structures and, in particular, may represent structures that incorporate soft or elastic materials, material deformation, composite materials, and pre-stressing.

Each block 100 of
The end faces 102 may each have a different shape or both end faces 102 may have a generally identical shape. Each end face 102 has a plurality of side edges 106 which form the periphery of the end face 102. As shown in
Each block 100 includes one or more holes 110 that extend between the end faces 102. As shown in
The holes 110 are arranged in the block 100 in orthogonal rows and columns. The openings to the holes 110 are positioned on the end faces such that the holes 110 are arranged in one or more parallel rows and/or one or more parallel columns. That is, a hole 110 belongs to at least one row of holes and/or at least one column of holes. For example, block 100a contains holes 110 that are arranged in a single row (of six holes), whereas block 100b contains holes 110 that are arranged in three rows and eight columns. It will be understood that the terms “row” and “column” may be used interchangeably to refer to a group of holes 110 that are arranged along a straight line. The rows and columns run parallel to the side edges 106. More specifically, the side edges 106 of an end face 102 define two orthogonal axes on the plane of the end face 102 such that each side edge 106 extends parallel to one or the other of the axes, and the rows and columns of holes 110 are respectively parallel to one of the axes.
The relative positioning of the holes 110 can be alternatively specified. In at least some embodiments, the holes 110 may be arranged in the block 100 according to a grid pattern. A regular grid, such as a Cartesian grid or rectilinear grid, may be used to specify the placement of the holes 110. For example, the holes 110 may be distributed in the block 100 such that each hole 110 is centered at a vertex point (i.e. the point of intersection of two perpendicular grid lines) of a grid that is imposed (e.g. overlaid) on the end faces 102. That is, the lines connecting pairs of adjacent holes 110 may form a grid. As a result, the holes 110 may themselves be arranged in a regular grid of spaced rows and columns. For example,
The holes 110 of
In at least some embodiments, the holes 110 may be positioned in the block 100 such that all of the holes which are adjacent to a side edge 106 are separated from the side edge 106 by a predefined, fixed distance. For example, for each side edge 106, the distance between the side edge 106 and the holes that are immediately adjacent to that side edge 106 may be equal to half of the width of the holes 110. In particular, the row/column of holes 110 which are nearest to a side edge 106 may be spaced from the side edge 106 by a distance equal to half of the width of the holes 110.
Reference is now made to
The holes 210 defined in the blocks 200 are arranged in one or more rows and/or one or more columns which are orthogonal to the rows. That is, each hole belongs to a row of holes 210 and/or a column of holes 210. For example, referring to block 200b, each hole 210 of the block is positioned in a row (r1 or r2) and/or a column (c1) which is perpendicular to both of the rows. In

A connecting member 400 includes one or more rod portions 410. A rod portion 410 is generally elongate and has a uniform cross-section along its length. Each rod portion 410 is sized to fit through at least some of the holes in the blocks of set 1000. More specifically, a rod portion 410 of a connecting member 400 has a cross-section profile which allows the rod portion 410 to fit through one or more holes in blocks of set 1000. For the blocks 100 of
The connecting member 400 includes a stem. The stem may be a straight and elongate bar or tube. In at least some embodiments, the connecting member 400 also includes one or more arms which are connected to and coplanar with the stem. Referring to
In
A connecting member 400 can be used to connect two or more blocks of set 1000. In particular, the rod portions 410 of a connecting member 400 are configured to engage the holes defined in the blocks of set 1000. A rod portion 410 can be threaded through holes on two or more different blocks that are axially aligned. Accordingly, in some embodiments, at least one rod portion 410 of a connecting member 400 may have a length which is greater than or equal to the thickness of one of the blocks that are being connected by the connecting member 400. For example, for a subset of blocks, each of which has the same thickness, the rod portion 410 of a connecting member 400 for the subset may have a length that is an integer multiple of the thickness of a block of the subset.
In at least some embodiments, a rod portion 410 of a connecting member 400 may fit through holes on one or more blocks such that it frictionally engages the holes. For example, a plurality of blocks may be positioned relative to each other such that at least one hole from each of the blocks is axially aligned with corresponding holes from the other blocks, and a rod portion 410 of a connecting member may be threaded through the aligned holes, forming a friction fit with one or more of the aligned holes. Each of the blocks that is frictionally engaged may then be secured to the rod portion 410, and the blocks may be held in fixed relative position to each other by the rod portion 410. In some embodiments, a rod portion 410 may fit rotatably in one or more holes on blocks. That is, the rod portion 410, once threaded into a hole of a single block or into axially aligned holes of multiple blocks, may be freely rotatable inside the hole(s). This type of connection may allow a block that is engaged by the connecting member to move (e.g. rotational motion) relative to the rod portion 410 as well as other block(s) that are also engaged by the connecting member 400. In some embodiments, the size of a hole may be greater than the cross-section of the rod portion. For example, a rod portion (e.g. an elongate rod having a length greater than the thickness of a block) may be threaded through a hole defined on the block such that the block is freely slidable (as a result of the hole being larger in size than the rod cross-section) with respect to the rod portion.
In at least some embodiments, a connecting member 400 may include two or more rod portions 410. For example, the connecting member 400d includes a pair of mutually perpendicular rod portions 410 which form an ‘L’-shape. As another example, the connecting member 400e has four rod portions 410, with each adjacent pair of the rod portions being perpendicular to each other, thereby forming an ‘X’-shape. As illustrated in
When building a structure using the set 1000, two or more connecting members 400 may themselves be coupled to each other, allowing for complex combinations of blocks and connecting members 400. In some embodiments, at least one connecting member 400 of the set 1000 may be perforated, having one or more holes defined on either the stem and/or arms of the connecting member 400. These holes may accommodate insertion of a rod portion 410 of a connecting member 400 through the body of another connecting member 400. For example, a rod portion 410 of a first connecting member may be frictionally fit through a hole on a second connecting member such that the rod portion 410 of the first connecting member is rigidly secured to and oriented perpendicular to the portion (i.e. stem or arms) of the second connecting member containing the hole. The holes/bores in a connecting member 400 need not extend perpendicular to the surface of the connecting member 400. For example, a hole in a connecting member 400 may be oriented at a slant (i.e. non-orthogonal) angle relative to the surface of the connecting member 400. In this way, a rod portion 410 of a first connecting member that is inserted through the hole of a second connecting member may be held at a desired, non-orthogonal angle with respect to second connecting member.

In at least some embodiments, the one or more holes 620 extend along a respective one of the rows and columns in which the holes 610 are arranged. That is, a hole 620 may extend parallel to and in alignment with either a row or a column. As a result, a hole 620a extending between a first pair of opposite side faces may be orthogonal to another hole 620b extending between a different pair of opposite side faces. The additional holes 620 may increase the minimum thickness, or the perpendicular distance between the end faces 602, of the block 600. In particular, in some embodiments, the block 600 may have a thickness equal to or greater than two times the width of the hole 620. For example, the thickness of the block 600 may be between ⅛ and 5/16 inch.

As in structure 700, a set of connecting members and/or beams can be used to maintain two blocks (or layers of blocks) in spaced relation to each other, and the connecting members themselves may be fixedly supported in spaced relation to each other. The structure 700 may, in some embodiments, be a modular building unit which can be assembled with other building units constructed using components of the set 1000. For example, one or more further connecting members/beams that are oriented perpendicular to the connecting members of the set can be received in the space between two adjacent and parallel blocks. Such further connecting members may then allow development of structures that is generally perpendicular to the original line of development (e.g. vertical development). Similarly, the space between adjacent pairs of connecting members can receive one or more blocks and/or connecting members of the set 1000 to form a complex, composite structure expanding beyond the modular unit.
In at least some embodiments, the blocks of layers 702a-d may be made of a different material than the connecting members and/or beams. For example, the plurality of blocks of the layers may be constructed from a rigid material, such as metal, wood, hard or ABS plastic, cardboard, etc., while the connecting members may each be made of an elastic material (e.g. polyurethane rubber), and/or a deformable material (e.g. rubber-coated steel foil). In some cases, one or more of the blocks may themselves be made of a different material than the other of the blocks. For example, some of the blocks may be made of an elastomer, such as silicone rubber, whereas other blocks may be made of wood. More generally, the components of the example set 1000 may be made from different materials (e.g. rigid, elastic, or deformable) such that a composite structure built by assembling the components may comprise multiple parts with varying structural and chemical properties. In some embodiments, the blocks and the connecting members may be constructed from the same or similar materials.
Structure 800 includes blocks 802 which are mounted one on top of another and connecting members 804 that are threaded through holes in the blocks 802. The blocks 802 are formed into a “wall” that delimits the perimeter of an area (a square, in the case of structure 800). Specifically, the blocks 802 are arranged into a dense stack which structure is rigidly supported by the connecting members 804. The structure 800 may be a modular building unit which can carry a load and support one or more other building units in a compound structure.
In some embodiments, blocks and layers of blocks may be connected, at least in part, by threading fibers or yarns (strings) through the holes defined in the blocks. For example, high-strength fibers such as Dyneema™ and Spectra™ or elastic cords (e.g. Spandex) may be threaded through holes in the blocks and prestressed. Such fibers may be used in conjunction with the connecting members of set 1000 to flexibly connect and support a plurality of blocks in a structure.
In some embodiments, tapes (e.g. Tyvek tapes) may be used to join two or more blocks together. For example, if a tape (such as adhesive tape) is used to join two blocks, the tape may define holes that correspond in position, size, and spacing with the holes of the two blocks.

Variations of the innovations described herein will be apparent to persons of ordinary skill in the art, such variations being within the intended scope of the present application. In particular, features from one or more of the above-described example embodiments may be selected to create alternative example embodiments including a sub-combination of features which may not be explicitly described above. In addition, features from one or more of the above-described example embodiments may be selected and combined to create alternative example embodiments including a combination of features which may not be explicitly described above.
