ABSTRACT An interlocking frame for selective engagement with a plurality of adjoining interlocking frames is presented herein. The frame includes a frame body that defines an interior portion at least partially enclosed by a plurality of interior walls, a front face, a rear face, and a plurality of peripheral walls. The interlocking frame also includes a plurality of locking tabs each selectively and independently rotationally disposable between a retracted position and an extended position relative to the frame body. Each of the locking tabs has an arm that extends beyond the frame body when the locking tab is disposed in the extended position in order to engage with a corresponding locking slot of an adjacent frame.

A building block set having a series of blocks and screws for connecting blocks. The blocks are provided with screw holes to receive screws. The screws insert into a block and extend into a neighboring block. Some of the screws are provided with screw heads having threaded channels that are configured to receive terminal ends of other screws.

Disclosed is an assembly block including a plurality of frame bodies which have a flat panel shape and include a plurality of insertion holes having the same shape and size and passing therethrough at certain intervals along any one of a row direction and a column direction and a rivet key inserted into certain corresponding insertion holes of the overlapping frame bodies and rotated to couple the overlapping frame bodies.

A toy construction set includes first and second construction elements, a pin, and a fastener including a body and a head. Each of the first and second construction elements includes through-holes and grooves on two major surfaces, respectively, of the construction element. A thickness of each groove is substantially the same. At at least one end of each groove, an edge of the groove is curved. The pin includes a body having a cavity and a member. A first portion of an edge of the member is curved, and a second portion of the edge of the member is straight. A thickness of the member is not larger than the thickness of each groove. The member of the pin is fixed in place in one of the grooves of the first construction element when the first and second construction elements are coupled by the pin and the fastener so as to constrain the pin from rotating with respect to an axis of the body of the pin.

Disclosed are a connector and an assembly toy set including the same. The connector includes a body having an upper surface, a lower surface, and a plurality of side surfaces, a first coupling part disposed on at least one of the plurality of side surfaces, and a second coupling part disposed on the upper surface, the lower surface, or the side surfaces, except for the surface on which the first coupling part is disposed. The first coupling part has a column shape that protrudes from the surface on which the first coupling part is disposed and has a joint ball for joint coupling at an end thereof. According to the present invention, various connection postures may be provided by using the joint balls for joint coupling at an end of the connector. Accordingly, various desired models may be easily assembled.

The disclosed technology relates to a construction toy made of expanded plastic foam extrusions. These extrusions are assembled with or without fasteners into a wide variety of configurations and optionally the extrusions are cut safely to a desired size.

Interlocking panels are assembled to form modules, and the modules are assembled to form a modular display case, for displaying, transporting and storing objects such as models, display items or valuable collectibles. The interlocking panels include interlocking side edge ball key tab including a resilient, compressible ball key, and ports for removably receiving the ball key tab and ball key.

The invention relates to a toy building element for a modular building game. The toy building element comprises one or more hollow coupling studs for coupling the toy building element to another toy building element in a releasable manner. Each coupling stud extends along a respective longitudinal axis and defines internally an axial through cavity configured to receive, in a removable manner, a locking stud apt to lock the toy building element to another toy building element coupled thereto. Each coupling stud comprises a coupling part and a receiving part for receiving the coupling part of a coupling stud of another toy building element. The coupling part comprises at least a radially flexible portion for engaging/disengaging a receiving part of a coupling stud of another toy building element. The radially flexible portion is configured to cooperate with one said locking engaging the cavity so that its radial bending is limited by the locking stud so as to prevent the coupling part from disengaging from the receiving part of a coupling stud of another toy building element.

A toy construction set includes first and second construction elements, a pin, and a fastener including a body and a head. Each of the first and second construction elements includes through-holes and grooves on two major surfaces, respectively, of the construction element. A thickness of each groove is substantially the same. At at least one end of each groove, an edge of the groove is curved. The pin includes a body having a cavity and a member. A first portion of an edge of the member is curved, and a second portion of the edge of the member is straight. A thickness of the member is not larger than the thickness of each groove. The member of the pin is fixed in place in one of the grooves of the first construction element when the first and second construction elements are coupled by the pin and the fastener so as to constrain the pin from rotating with respect to an axis of the body of the pin.

A toy construction set comprising operatively interconnectable blocks and connectors. Each of the blocks has one or more apertures formed in relief. Each of the connectors has a base in the form of a plate or rod and a plurality of pins attached to the base in a spaced apart arrangement for interconnecting blocks. The pins are integral with the base plate. The interconnection between a block and a connector is achieved by the pins being positively engaging and releasably retained within one or more of the apertures of the blocks. The pins are oppositely disposed of a base plate so that a block can be connected to a connector on one side of the base plate, and another block can be connected to the same connector on the other side of the plate.
