A Toy assembly includes a flexible joint element and a construction member. The flexible joint element comprises two spherical components and a flexible string. The two spherical components are coupled to the flexible string at the two ends of the flexible string. The construction member comprises two slots and two holes which can receive the flexible joint element. Multiple construction members can be assembled, utilizing flexible joint elements, to construct toys or other structures with members having six (6) degrees of freedom.

A construction system uses a comb connector element in combination with flat or generally planar polygonal shapes of various types. The comb connector elements connect to the edges of the planar polygonal shapes. Each comb connector has at least one pair of connector members. Each connector member has a proximal end connected to the polygonal member, and a distal end. Each connector member having a face portion that includes a recess extending from a central region of the face portion. The recess extends to the distal end of the face member.

Building sets including a plurality of blocks and a plurality of clips configured to engage a thickness of one or more of the blocks. Each clip includes a base and first and second substantially parallel extensions extending from the base and defining a channel therebetween into which a thickness of a block is receivable. The width of the channel is substantially equal to and slightly less than the thickness of the block receivable within the channel so that the thickness is frictionally retained therein. The clip may include a magnet enclosed within the base so that the base of a first clip may be magnetically coupled to the base of another clip, and each clip may in turn be frictionally coupled to a block received between the extensions of the respective clip. In one embodiment, the clip includes a plurality of channels.

A linkage that couples a plurality of Lego blocks or Lego-like blocks is posable and configured to provide a plurality of three-dimensional orientations for the plurality of blocks it interconnects.

Toy connection systems comprise a plurality of planar wall panels and a plurality of clips each configured to connect one or more of the planar wall panels to each other. Each wall panel comprises at least one connecting edge and at least one slot. Each clip comprises at least one receiving channel configured to releasably receive the connecting edge of a respective one of the wall panels and a tab that is configured to be received within the slot of the wall panel to secure the wall panel to the clip. In some examples, the clips are configured to be biased against the wall panels that are connected using the clip, such that the tab of the clip is configured to be snapped into the slot of the wall panel that is received within the receiving channel of the clip.

A 3D fort building kit is a device that can create a variety of structures and shapes. In other words, the device has improved materials and designs with better qualities, that enables kids to build complex 3D structures. To accomplish this, the device includes panels, connectors and utility features that help kids to construct and assemble a structure of their choice in many designs. Further, structures may be constructed in many creative designs by allowing the panels to be connected vertically, horizontally, and at any angle. Furthermore, the constructed structures can be disassembled and constructed again to build other designs safely by kids. Additionally, the device is simple, durable, and light weight enough for young kids to build stable and versatile structures of their choice.
