An environmentally friendly knockdown building block set includes a cardboard shipping box; a plurality of main cardboard blanks each configured to form a base block including four connecting slots therein as wide as the base block thickness; a plurality of coupling cardboard blanks each configured to form an H-block including two connecting slots therein with each slot located between two legs of the H-block and as wide as the H-block thickness; wherein the connecting slots of each base black and each H-block allow for receipt and interconnection of the base block or H-block with an associated base block or H-block forming a notched connection for the base blocks and H-blocks; wherein at least the main blocks include an inking pattern using plant based environmentally friendly inks; and wherein the shipping box is an integral component configured to be integrated into structures formed by the set.

A play structure is formed from flexible struts supporting a fabric. The struts are inserted through pockets along the edges of the fabric. The struts are joined together by connectors at apexes of the structure. The struts form an upper frame and a lower frame. The upper and lower frames are connected by battens. The struts and battens hold the fabric in a selected shape, such as a sailboat. The battens are formed from flat, flexible members that are bent about their longitudinal axis to form a C-shaped cross section. Ends of the battens are inserted into curved batten receivers on the connectors. When a downward force is applied, such as when a child sits or steps on the structure, the upper frame is pressed toward the lower frame. The battens bend and flatten to resiliently allow the structure to collapse. When the force is relieved, the battens resiliently resume their curved shape, restoring the structure to its original configuration.

The present invention provides an assembly of edible articles, more specifically, which by virtue of their composition are able to form complex frameworks in usage of two or more of such embodiments to interconnect. The complexity of structures reflects upon the imagination of the user.

A method of forming a foam block capable of being securely assembled to a different foam block to create a structure that is larger than the foam block is described herein. The method includes the following features. The foam block is received. Channels are formed in at least one side of the foam block. At least some of the channels are formed to accept a securing member that restricts vertical and horizontal movement of the foam block when the foam block is secured to the different foam block.

A construction support device is disclosed for support and assembly of planar members into complex structures. A construction support device can comprise a first and second unit that are separable where each support unit comprises a plurality of sinuate grooves between a plurality of sections with sinuate edges. The sections are flexible about a center to increase the width of the sinuate grooves to receive greater thickness of planar members. A cubic embodiment with flat outer surfaces and a spheric embodiment with round outer surfaces are disclosed.

A construction kit enables building of complex structures. The kit can include pole connectors, along with a series of hubs. For instance, two-point hubs, four-point hubs, eight-point hubs, five-point hubs, six-point hubs, and a clip can be the constituent parts of the kit. Some of the hubs can be flexible to provide further utility and additional angles for building. Complex structures, such as a ball-shaped connector can also be achieved from the base components.

A connector block for an interlocking block system and an interlocking track system includes a first portion having an intermatable track segment of the track system and a second portion having a block interface of the block system, with the track segment offset from the block system. The second portion preferably includes at least two block interfaces of different genders with each configured to mate with elements of the other gender. The underside of the block interface defines a horizontal lower plane without protrusions and defines protrusion-receiving receptacles. An upper block interface defines a horizontal upper plane and includes a plurality of protrusions extending beyond the upper plane and configured to be received in the protrusion-receiving receptacles. The interoperable connector block may include a sloped track segment, and is preferably a body formed of a single material. The connector block is preferably intermatable with Duplo® and Brio® modular components.

The invention describes a new constructor module with the additive aspects of sound and dynamic construction. A base block is provided with varying mating elements for adjustably connecting structural blocks and plates together with sounding elements. A plurality of base blocks may be constructed based on desired output in various shapes and structures. The base blocks are coupled together with connecting elements and fixing pins, which also assist in coupling the sounding elements. Additional plates are also utilized for creating dynamic sounds and structures, including D-shaped plates and U-shaped plates. Constructor set modules may utilize all such elements in a plurality of structures, or at minimum, only base blocks, connecting elements, a sounding element, and fixing pins.

The application relates to a field of object connection and in particular, relates to a basic connecting block and a connecting block group. The basic connecting block includes a connecting block body, wherein at least one protrusion corner is provided on one side of the connecting block body and same number of inward recesses as the protrusion corner are provided on an opposite side of the connecting block body, and wherein a surface contour of the protrusion corner is consistent with that of the inward recess, the protrusion corners are connected with each other and the inward recesses are communicated with each other.

A card-connector is provide for the construction 3-dimensions objects with cards, such as playing cards. The card connector can include a card receiving portion and an interconnection portion. The card receiving portion can be bifurcated to define a first side portion, a second side portion, and a slot. The interconnecting portion can have at least one of a ball portion or socket portion of a ball and socket joint, where two interconnecting portion can be connected to form a ball and socket joint. Multiple card connectors can be joined together with the interconnecting portions to create 3-dimensional objects with the cards.
