Abstract
Description
- The field of the invention is children's multi-purpose building blocks. The present invention relates to the field of toys and construction sets. More specifically, the present invention relates to a plurality of detachably connectable blocks capable of being slidably attached to one another to form geometric structures.
- Many children's building block products are available today, however their appeal is limited by their restricted shapes, fixed interlocking joints, and limited interlocking joint surfaces. The inadequate variety of available shapes severely limits the child's imagination by only allowing the creation of geometric structures with a minimal choice of angles. In addition, the fixed interlocking joints further limit the positioning of the blocks where the lack of intermediate interlocking joint positions restricts the structural possibilities that call for increased precision. Finally, the inadequate number of interlocking joint surfaces unnecessarily limits the structural possibilities of the resulting formations.
- The invention provides basic geometric building block pieces capable of combining with other, basic geometric building block pieces to form three-dimensional models. The basic building block piece comprises alternating offset layers of a flat, geometric member with uniform thickness, to form a plurality of ridges and grooves to enable the desired variety of connection configurations with other, basic geometric building block pieces, to form various three-dimensional structures. The variety of geometric shapes and corresponding interlocking joint surfaces provide for increased structural possibilities over the prior art. For example, horizontally rotating one block 180 degrees can produce either a 1-layer or a 2-layer vertical shift incline. In addition, the plurality of ridges and grooves provide for unlimited combinations of slidable connecting interlocking joints. In one embodiment, completed structural forms utilize the various geometrically angled pieces to create unique aesthetic patterns and relationships.
