This disclosure provides methods, systems, and kits for building seawalls using mechanically interlocking blocks. The interlocking blocks have interiors that can be filled with sand, gravel, or cementitious material after formation of a wall. The interlocking blocks that can be connected on any side to form a structure, wall, foundation, floor, building, flotation device, gardening structure, or toy. The interlocking blocks typically comprise center openings and connecting openings on each side and can be connected with hardware through the connecting openings. The center openings allow for materials such as pipes, wires, conduit, and rebar to pass through interlocked blocks. Connected blocks can also be filled with fortifying material to strengthen the structure. Sides of connected blocks can be covered with faceplates to direct flow of fortifying material and aid in the creation of desired configurations. Also provided are connectors for connecting sides of the interlocking blocks.

A construction set for erecting structures that can be assembled and disassembled. The technical result consists in expanding the functional capabilities of a construction set, which makes it possible to assemble a high-strength structure.

A plate connecting assembly according to an embodiment includes a first frame, with an upper portion and a lower portion of the first frame making a predetermined angle with each other, and a second frame having a first support portion facing the upper portion and a second support portion facing the lower portion. In the plate connecting assembly, a first fixation-subject object is fixed between the upper portion and the first support portion, a second fixation-subject is fixed between the lower portion and the second support portion, and thus the first and second fixation-subject objects are fixed in such a manner that an angle therebetween is the same as an angle that the upper portion and the lower portion make with each other.

Toys that comply with at least American Society for Testing and Materials educational and safety standards are provided. Embodiments include grasping toys, rattle toys, rolling drum toys, shape fitting toys, and hex with ball toys.

The present invention provides a construction frame comprising a front side, a back side, and a side part, wherein said construction frame further at least one receptacle in the side part. Further, a system comprising at least one construction frame according to the invention is provided. In a preferred embodiment said system comprises at least two construction frames which are connected by at least one connector, which is inserted in the at least one receptacle of each construction frame.

The present description relates to an assembly type toy. The assembly type toy of the present description includes: a first toy including a first hexahedral block, wherein one or more first male type blocks are mounted on at least one surface of the first hexahedral block; a second toy including a second hexahedral block, wherein one or more first female type blocks are mounted on at least one surface of the second hexahedral block, and the first female type blocks each have an accommodation hole provided therein to accommodate the first male type blocks; and a third toy including a pair of hexahedral blocks that come in surface contact with each other, wherein one or more second male type blocks are mounted on at least one surface of one block of the pair of hexahedral blocks, one or more second female type blocks are mounted on at least one surface of the other block, and the second female type blocks each have an accommodation hole provided therein to accommodate the first male type blocks.

An interlocking toy block display mount with a plurality of sides with multiple sides having mail interlocking members or female interlocking members disposed thereon. A plurality of bore holes pass through top, side and end sides of the mount along three axes and intersecting at the substantial center of the mount with a fastener inserted through one of the bore holes to secure the mount to a surface.

According to one embodiment, a modular toy assembly system featuring one or more bases and a plurality of posts. Coupled to recessed connectors of the base, the plurality of posts includes a first end connector and a second end connector for coupling to different bases to provide depth of the toy. The posts include a first elongated body element and a second elongated body element interposed and extending between the first end connector and the second end connector. The first elongated body element and the second elongated body element are oriented to produce (i) a first slot between a first side of first elongated body element and a first side of the second elongated body element and (ii) a second slot between a second side of first elongated body element and a second side of the second elongated body element.

A method and system of attaching rivets to secure sheets of paper together. The rivets have a head, a recess, a skirt and a tail. A tool is configured so that the tail fits through a hole in the tool. Before the tail is inserted into the hole in the tool, the tail is inserted through two holes in the paper(s) and then in the hole in the tool. Pressure is placed on the paper by pressing downward on the tool thereby causing the paper(s) to snap into the recess, thereby securing both pieces of paper together.

A modular inflatable structure can be formed using inflatable members that are interconnected together at respective joints. The inflatable member can have a connector integrated therewith or be coupled to a separate connector that interconnects adjacent inflatable members. The connector can have flexible and/or rigid components. The structure can have an assembled position in which the inflatable member is coupled with an adjacent inflatable member and flow is permitted therebetween. The structure can be inflated to form a support or framework that can be used in a variety of applications and industries.
