A snap-fit connector includes a female component and a male component. The female component has a retaining hole and two through bores communicating spatially with the retaining hole. The male component has two spaced-apart hooks inserted into the retaining hole. Each of the hooks has a resilient arm, and a protrusion retained in a respective one of the through bores. The protrusion of each of the hooks has an abutment surface abutting against the female component, and a positioning recess formed in a guide surface thereof and accessible via the respective one of the through bores.

A protective cover for a handheld portable electronic device includes a front cover, and one or more mounting portions. The mounting portions can couple the front cover to the handheld portable electronic device. The front cover can cover the display screen of the portable electronic device. The front cover, the mounting portions, or both include studded surfaces or socket surfaces. The studded surfaces or socket surfaces couple with standard building elements of a play building set.

A cost effective, structural building set, suitable as a toy, uses post connectors (10) comprised of a post (12) with attached disks (14), or similar devices that insert into cutouts (31) in geometric shaped component parts (30, 80, 180). More than one component part can be connected to the same post connector, and such component parts can rotate relative to the post axis. The connector design allows construction of stable structures of many sizes, shapes, and types, and readily facilitates hinging between different sections of such assembled structures.

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.

A coupling for assembling at least two beverage cans together, comprising at least a pair of collar portions, each to slidably receive a corresponding end region of one of the beverage cans, the collar portions being configured to engage the beverage cans for associated games and/or other amusement activities.

Assembly of two construction elements (1) which each comprise a number of side faces and are provided with a connecting means (2) for connecting the construction elements (1) to one another. The construction elements each comprise a side face with a recess (3), the recess (3) having been produced by cutting away a part (4) from the construction element (1). The slidable parts (4) are slidable in the recesses (3) and form the connections (2). A method of connecting such construction elements (1) to one another is also provided.

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.

The invention is a construction toy consisting of standard connector elements, e.g., rings, and strut elements, e.g., that may be joined in various angular configurations and with various types of articulation such as fixed, sliding, swinging, spinning, etc. Rings may be provided that have pairs of perimeter orifices that are offset by different amounts wherein the different offsets provide different functionality to ring and strut assembles. Other elements may be included such as pipes, slips, caps, base components and collar components. The elements may be combined to create various forms including a figure with human traits comprised of interconnecting strips and rings of various dimensions, a decoration, a vehicle, a bird, or many other forms in accordance with a user's imagination.

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.
