A method comprises sending to a computer processor a log-in identifier to access a virtual garage stored in an online database. The virtual garage can contain computer code representing at least one vehicle stored in the virtual garage, and the vehicle being comprised of a plurality of components. Instructions can be sent to the computer processor from the first party to display the at least one vehicle in the virtual garage. A replacement component for at least one of the plurality of components is selected and sent by the first party to the computer processor, along with instructions to replace the component with the replacement component to create a new vehicle. Once the new vehicle is created, it can be displayed on the end user device.

A model vehicle is a combination of a wooden body and a wheel assembly providing free rolling wheels to provide increased functionality, usability, durability and nostalgic quality design. The wheel assembly includes a molded body, metal wire axles traversing the molded body and wheels mounted to each end of the axles. The wheel assembly is mounted to an underside of the wood body. The molded body may include an opening to allow a screw to pass therethrough to secure the wheel assembly to the wood body. The molded body may include a protrusion to assist with alignment of the wheel assembly and wood body. The molded body may include a receptacle to house a magnet to enable connection to an additional model vehicle to be towed. The wood body may include a lower piece and an upper piece secured together.

An educational toy that is formed of parts that function as tools. For example, a toy car axle can be a screwdriver.

A building block system includes one or more building blocks and one or more wheels, each building block including a first elongate portion extending in a longitudinal direction, a second elongate portion extending in that longitudinal direction, an intermediate portion connecting the first elongate portion with the said second elongate portion at a middle position thereof, a first end portion extending in a transverse direction, perpendicular to that longitudinal direction, from the first elongate portion, at a side thereof opposite to the intermediate portion, and at a middle position thereof. A second end portion extends in that transverse direction, perpendicular to the longitudinal direction, from the second elongate portion, at a side opposite to the intermediate portion, and at a middle position thereof. It thus includes six protrusions and two voids, each void defined between an end of the first elongate portion and an end of the second elongate portion.

A Lynchpin structure may be combined with one or more additional Lynchpin structures to form a compound Lynchpin propulsion structure. Each Lynchpin structure may include six pentangular areas, and one or more of the pentangular areas may include a propulsion device. The propulsion may be used to propel the compound Lynchpin propulsion structure through or over various media, such as through air, across ground, on or underwater, or through or over other media. The propulsion may include avionic propulsion, ground propulsion, hydrodynamic propulsion, or other types of propulsion. A single type of propulsion device may be used within one or more of the pentangular areas, or diverse types of propulsion may be used to provide various navigational performance or multi-mode operation. Each propulsion device may also include a device to direct the propulsion, such as a single or multi-axis gimble or adjustable aerodynamic control surface.

Described is an apparatus for building a junk model, comprising an elongate member (118) attachable to a junk model body (106) and having a first end region and a second end region; a first attachment portion (130) for attaching a first surface engaging element (114) to the first end region; and a second attachment portion (132) for attaching a second surface engaging element (116) to the second end region; wherein the elongate member is selectively adjustable in length to set a distance between the first attachment portion and the second attachment portion. A kit of parts and method of building a junk model are also provided.

The invention relates to a modular construction system comprising at least one object and a coupling element releasably connectable to the object, wherein: the object comprises at least one surface with at least one opening, which opening comprises a number of inward extending lips arranged distributed over the periphery of the opening; the coupling element comprises a body with an axial axis arrangeable in the opening, which body is provided along its outer periphery with at least one outward extending locking cam; wherein the coupling element is arrangeable in at least one arranging orientation in the opening of the object, and is rotatable in the opening relative to the object to at least one locking orientation, in which locking orientation the coupling element is locked in an axial direction and a rotational direction. The invention also relates to a coupling element, object and tool intended and configured to form part of such a modular construction system. External elements such as a skin plate, a fabric, a cord or the like can be attached to a structure according to the invention by means of an attaching element with a shank and a widened head, which shank can be inserted releasably into a continuous opening of a coupling element.

Recreational device including support including first guide defining main axis, slider movably constrained to the support and movable along the main axis, at least one covering element configured to be detachably constrained to the support, elastic element constrained to the slider and to the support and acting between them along the main axis. The elastic element defines a rest configuration wherein it is in a rest position between slider and support and an operating configuration wherein slider and support are in contrast to the elastic element. The covering element includes at least a first interaction surface, the slider includes at least one component protruding outwards and defining at least a second interaction surface configured to interact with the first interaction surface, and the second interaction surface is configured to undo the connection between covering element and support when the elastic element is in operating configuration.

An unpowered downhill autonomous car kit is provided for a user to build. The kit includes a control circuit board, a servo, and a roadway detection sensor. The control circuit board is programmed by a user to interpret patterns marked on a race course that are detected by the roadway detection sensor, and then the control circuit board instructs the servo to steer the car based on the detected roadway patterns. The challenge is for the user to program the car kit in a manner such that during a race, the car will avoid vertical barriers on the race course by correctly interpreting the patterns viewed by the roadway detection sensor. The roadway patterns are intentionally not consistent as the car moves from one roadway segment to the next, so as to increase the technical challenge.

The present disclosure provides a child-mother toy, including: a first assembly and a second assembly. The second assembly includes a supporting member, a triggering subassembly, a unfolding subassembly and an ejection subassembly, and the triggering subassembly, the unfolding subassembly and the ejection subassembly are disposed to the supporting member. Before the triggering subassembly is triggered, the unfolding subassembly is folded at the supporting member so as to define an accommodating cavity together with the supporting member, the accommodating cavity is configured to accommodate the first assembly therein; and after the triggering subassembly is triggered, the unfolding subassembly is unfolded to open the accommodating cavity, and meanwhile the ejection subassembly ejects the first assembly out of the accommodating cavity.
