A vehicle configured to move through a network of interconnected tubes includes a body, a motor, a motorized wheel, a biasing assembly, and a first element. The motorized wheel directly engages an inner surface of the tubes. The biasing assembly causes the motorized wheel to maintain continuous contact with the inner surface of the tubes during operation. A waist of the vehicle is constrained by an inner diameter (D) of the curved tube, a radius of curvature (R) of the curved tube, and a length (L) of the wheelbase of the vehicle. The waist of the body is sized such that the vehicle can freely move within any of the tubes without getting stuck therein.

An electronic toy vehicle track that abruptly stops selected cars along their path of travel based of their progress on the course. The abrupt stoppage can occur as a result of a vehicles position relative to other vehicles on the track, time duration on the track, traveling at too low of a speed for any period of time or combinations of such data or other data. A selected car may abruptly stop by such methods as crashing into an obstacle having a disruption in its lane of travel by something such as a collapsing bridge.

A system and method is provided for a toy race track. Preferred embodiments of the present invention operate in conjunction with a vehicle affixed to a track, wherein the track is supported in relation to at least one fixed surface via a plurality of support structures. In one embodiment, the track comprises a plurality of flexible sections, allowing a user to construct a track resembling a rollercoaster, having steep curves, upside-down portions, etc. In one embodiment, the vehicle includes a plurality rollers that can be used to both affix the vehicle to the track and propel the vehicle along the track. By affixing the vehicle to the track, the vehicle is prevented from leaving the track during extreme situations (e.g., steep curves, upside-down portions, etc.).

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.

Provided is an assembly connection member including a body, and a cylindrical rotary insertion member inserted in the body. The cylindrical rotary insertion member includes a first cylindrical rotary insertion member inserted to an opening of a circular shape formed in a center of an upper body, a second cylindrical rotary insertion member inserted to an opening of a circular shape formed in a center of a side surface of the upper body, and a third cylindrical rotary insertion member inserted to an opening of a circular shape formed in a center of an opposite side surface of the upper body.

An improved toy vehicle transfer station playset is disclosed herein. The playset includes a support frame that extends upwardly from a support surface. Coupled to the support frame is a slide rail having a first end and a second end. The first end is disposed higher than the second end with respect to the support surface. A carrier is movably coupled to the slide rail, and is configured to move along the slide rail from a first position proximate the first end to a second position proximate the second end of the slide rail via gravity. The carrier includes a track section for receiving a toy vehicle. The playset also includes a retaining mechanism disposed on the slide rail and configured to retain the carrier in the first position. However, when a toy vehicle is disposed on the track section of the carrier, the retaining mechanism releases the carrier to move along the slide rail to the second position.
