The interface face includes a recess, a plurality of connection apertures disposed proximate to the edge of the recess, and a circular interface receptacle disposed in the center of the recess. The kit also includes modular construction connectors, each includes two opposite sides, wherein each side including a body, a plurality of connection studs extending outwardly from the body, and a protrusion extending outwardly from the body. Some modular construction blocks include predetermined functions. A modular system block includes at least a processor, storage, and wireless communication.

A body of a mobility includes: a base part disposed outside a cabin room and extending in a longitudinal direction of the body, and including a first coupling surface; a fixed part extending in the longitudinal direction and coupled to the base part, and including a second coupling surface matching with the first coupling surface, the fixed part having an insertion hole being open toward one side thereof and extending in the longitudinal direction; and a pillar member having a first end inserted into the insertion hole of the fixed part to be coupled to the fixed part and a second end extended and being curved.

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.

An assemblable story and picture display may include a plurality of substrates combinable to resemble an object. The assemblable story and picture display may define an outer profile that may resemble an apple, banana, duck, egg, Christmas tree, or any other relatively simple object. Each of the plurality of substrates may define a portion of the outer profile making up the assemblable story and picture display. Each of the plurality of substrates may include a portion of a story or images wherein the story is conveyed sequentially across the plurality of substrates. The assemblable story and picture display may further include an outer decorative image or layer. The assembled story and picture display may include exterior decorative elements indicating the nature of the story depicted on each of the story or display layers.

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.

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 door hinge assembly includes: a door frame defining a frame opening and a jamb at one side of the frame opening, the jamb including two frame corners protruding into the frame opening and a jamb brace connecting the two frame corners across the frame opening, the jamb brace defining two spaced-apart hinge holes therethrough; a door movable to selectively provide access through the frame opening, and an elastic cord connecting the door to the door frame, the cord extending sequentially through a first of the two hinge passages, through a first of two passage openings at the jamb edge, through a first of the two hinge holes, across the jamb brace, through a second of the two hinge holes, through a second of the two passage openings at the jamb edge, and through the second of the two hinge passages.

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.

An assemblable story and picture display may include a plurality of substrates combinable to resemble an object. The assemblable story and picture display may define an outer profile that may resemble an apple, banana, duck, egg, Christmas tree, or any other relatively simple object. Each of the plurality of substrates may define a portion of the outer profile making up the assemblable story and picture display. Each of the plurality of substrates may include a portion of a story or images wherein the story is conveyed sequentially across the plurality of substrates. The assemblable story and picture display may further include an outer decorative image or layer. The assembled story and picture display may include exterior decorative elements indicating the nature of the story depicted on each of the story or display layers.
