The invention provides a holding device comprising a locking member having a longitudinal axis, an external surface and a first end, an actuator for displacing said locking member along its longitudinal axis between a holding position and a released position, a guiding part, for engaging said external surface of said locking member and guiding its displacement functionally along its longitudinal axis, and an alignment sensor for detecting alignment with another device having a complementary guiding part, complementary with said locking member, said alignment sensor functionally coupled with said actuator for displacing said locking member when alignment with said complementary guiding part is sensed.

A craft kit (100) of separate parts adapted for assembly into an article and instructions therefor is described. The craft kit (100) includes a frame part (110) in the form of a handgun shape, the frame part (110) including a stock (112), a barrel (114), a hammer (113), and a trigger (115) integral therewith, and a pair of grip-shaped parts (120), each fixedly attachable via first fastening means to a respective side of the stock (112) on the frame part (110). The craft kit (100) includes a pair of semi-cylindrical shaped firing cylinder halves (130), each firing cylinder half (130) attachable via second fastening means to a respective side of the frame part (110). Each of the frame part (110), grip-shaped parts (112) and firing cylinder halves (113), together with the first and second fastening means, comprise the entirety of a non-lethal, handgun-shaped article assembled from the craft kit (100).

A set of castle building blocks comprising a plurality of brick units, city wall units, cylinder units, tower units, and connection units. All of the units excluded the connection units have at least two blind holes. Each connection unit includes a rod section and a head section connected with each other. The rod section inserts into the corresponding blind hole. The head section detachably inserts into the blind hole of one of the units excluded the connection units. A plurality of convex arc portions is inclined and extended upwardly and outwardly from the rod section axially. The head section includes a main body, a hollow portion, and a concave groove. The concave groove of the connection unit is arranged so that the main body of the head section has a space to elastically insert into the blind hole of other unit excluded the connection units.

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 present invention relates to a unit block having a coupling portion and an insertion portion provided in special structure and shape such that, instead of providing an assembly-type toy that makes a user build an assembly-type completed product according to the manual, the user is enabled to implement various articles by exercising creativity without feeling bored. The present invention provides a unit block, which has integrally provided coupling and insertion portions, and provides, as a means for using the same when a desired object is to be implemented, a unit block coupling means comprising: a unit block coupling portion, which has an insertion portion sized to be fitted into the coupling portion and narrowed by a degree corresponding to the outer wall of the coupling portion at the upper end of the coupling portion, thereby being integrated therewith, wherein circular penetration/coupling holes are formed on fourth side surfaces of the insertion portion, and partial tube extension portions are formed on the upper/lower/left/right sides of the penetration/coupling holes; the unit block is structured to have a -shaped inner extension concave groove at the center of the surface of the coupling portion; when vertically coupled to a different unit block, a -shaped support piece is fitted and coupled to the -shaped inner extension concave groove formed on the surface of the coupling portion; when horizontally coupled to a different unit block, partial protrusion portions, which are formed on the surface of a support shaft, are fitted to the partial tube extension portions formed in the penetration/coupling holes of the coupling portion; and the unit block coupling means is applied to secure a high degree of coupling force.

A tension compression structural unit and method of assembling structures that comprises endwise interlapping configuration of at least three elongate members into a tension compression structural unit whereby tensegrity is maintained by tensioning a first end of each elongate member against respective first ends of each other elongate member, in interlapped array, and then anchoring each second end of each elongate membereither onto a ground surface or by interlapped configuration with additional elongate members. A stable, domic structure is thus erectable without the need of additional tensioning elements such as wires or cables, for example.

The present disclosure relates to toy construction kits and assemblies and, more particularly, to connectors that are mechanically attached to and extend from the corners of geometric frame-like modules. The connectors are also adapted to interface with and magnetically connect to linear magnetic modules, whereby a user can create multiple construction platforms upon which a number of diverse and interesting structures can be assembled.

The disclosed invention is of a children's construction toy made of expanded plastic foam extrusions. These extrusions can be cut to a desired size and then assembled either with or without fasteners into a wide variety of configurations including log cabins, pirate ships, castles and cars.

A toy that is comprised of diverse cylindrical tubes, channels, and spouts to provide entertainment and educational value for the user through engineering a route for the transfer of water and other objects. These tubes are positioned in manners of various directions and secured to a surface, likely a shower wall or bath tub, with rubber suction cups or other affixing mechanism, which are easily repositioned and moved by the user. The issue addressed with this invention is as follows: children become easily bored and unengaged in the shower or bath, and this toy would provide for not only entertainment, but engineering experience for the child, as they would be constructing an effective path for the water.
