The present application discloses a splicing structure that can be broadly apply to toy, tool, furniture, handicrafts, jewelry or other fields. The splicing structure comprises a splicing block capable to detachably spliced with one another, said splicing block comprises a splicing hole and a splicing column. The splicing structure also comprises a plug piece having an insertion rod, said insertion rod having protrusions along its periphery; a receptacle having an insertion hole, wherein outer diameter of the protrusions, inner diameter of the insertion hole and outer diameter of the insertion rod decrease. The plug piece is mounted between the splicing column and the splicing hole, said receptacle is mounted within inner hole of the splicing column; when two splicing blocks are spliced through inserting a second splicing block into a first splicing block, insertion rod of the first splicing block is inserted into the insertion hole of the second splicing block by interference fit and the two splicing blocks are firmly spliced together by snap fit connection between the protrusions of the first splicing block and the insertion hole of the second splicing block.

A container adapter includes a soft sleeve having a first and a second anti-slide sleeve portion; a rigid connecting pipe having a coupling portion, a stop portion and a plurality of slots. The first anti-slide sleeve portion is forward tapered, and the coupling portion is backward flared. The rigid connecting pipe is connected at the coupling portion to the first anti-slide sleeve portion of the soft sleeve with the stop portion abutted on a rim of the first anti-slide sleeve portion. To use the container adapter, simply fit the second anti-slide sleeve portion of the soft sleeve around an end of a container. Decorative accessories can be set in the slots to form ornaments, or pipes can be connected to the container adapter to form a fluid passage for guiding a liquid in the container, such that the container can have more applications and be advantageous to environmental protection.

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 construction system which includes a first construction element which has a first thickness, and a second construction element which has a second thickness, and the first thickness is different from the second thickness, and each construction element defines at least one passageway extending therethrough; a fastener body telescopingly received in the passageway; a locking member cooperating with the fastener body and which, in a first position allows the fastener body to be received in the passageway, and in a second position, substantially impedes the removal of the fastener body from the passageway.

An interconnectable construction element has a body section, a first socket coupled to a first end of the body section, and a magnetic ball. The first socket has a recess in communication with an opening. The opening extends from a first lateral side of the first socket at least to a distal end thereof. The magnetic ball is individually rotatably receivable into the recess of the first socket for forming a magnetic connection with another interconnectable construction element having another magnetic ball.

A marble run track connection arrangement for use with a plurality of physically interconnectable marble run elements includes a marble track section, a tube, and a connector. The marble track section has first and second connecting posts coupled to or forming a portion of a marble travel path of the marble track section. The tube includes a connecting portion configured to directly physically connect to another tube. The connecting portion passes a marble from or to the other tube. The tube also has a side opening configured to receive a marble therethrough into or out of an interior of the first tube. The tube also includes a track connector extending outward from the tube. The connector is configured to receive the first and second connecting posts and to couple to the track connector such that a path is defined between the marble travel path and the interior of the tube.

A connection structure for toy tents having a first connection component, a second connection component and a connection buckle, the first connection component and the second connection component are clamped together, the connection buckle is clamped with the first connection component and the second connection component, an outer hemisphere of the first connecting assembly is clamped with an outer hemisphere of the second connecting assembly and an inner hemisphere of the first connecting assembly is clamped with the inner hemisphere of the second connecting assembly.

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 building toy includes at least one basic element and at least one connecting pin. The basic element has a body where in the wall there is at least one connecting opening led perpendicularly onto the wall. The connecting opening runs through the body of the basic element as a transitory cavity and the connecting opening is designed for an insertion of the connecting pin. All connecting openings in the body are mutually spatially skew. The pairs of connecting openings from each wall run through the body to lie in mutually perpendicular and rotated planes and the distance of the connecting openings if each pair is identical and it is at least the length of a diameter of the connecting openings. The pairs in the central zone of the body avoid each other without the cavities of the connecting openings colliding mutually.
