The connector clip having a maximum thickness that substantially corresponds with a height to which a barrel projects from the bottom surface of the baseplate, with at least one of the first and second heads of the connector clip configured to matingly engage with a number of barrels on the bottom surface of the baseplate in a press fit connection for use in joining the baseplate to a second baseplate.

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.

A modular play structure is disclosed. The play structure has a plurality of wall units that can interchangeably couple to form a modular playhouse. The wall units are coupled together by a mating structure. Some embodiments have a separate connector that couples wall units together at the edges of the wall units. Some embodiments have accessories coupled to the wall units at accessory openings. Some embodiments have decorative faades configured to removably attach to the plurality of wall units.

A wall component for receiving associated alignment clips is illustrated and described. The wall component comprises a molding strip, an array of mounting studs, and a molding frame that is inserted between a pair of wall panels. More specifically, the mounting studs are affixed to an inner surface of the molding strip and inserted through the wall panel where they are secured to the molding frame. A gap is formed between the inner surface of the molding strip and an outer surface of the wall panel for receiving associated alignment clips. The alignment clips are releasably secured to the wall component by interlocking with the mounting studs in the clip receiving gap and/or wedging the gap. The alignment clips may be affixed along an abutment edge of the wall segment or to associated model pieces. Model pieces may also be laterally slidable with respect to their associated alignment clips.

Embodiments include a construction toy kit having component parts capable of being assembled in a configuration chosen by the user. The kit may contain a connector extending from a first end to a second end, having a securement comprising a first retainer feature, a second retainer feature and a third retainer feature. The connector may further have a first grip extending from the first end toward the securement, where the first grip is sized to receive a feature of a building panel. The kit may also contain a multiple building panels of various configurations, a mat used as a base for erecting a structure and multiple sensor components. These components among others may be assembled to create structure such as a race course for robotic toys. The sensor elements may be implemented by the user to sense various actions of the robotic toy, and respond as chosen by the user.

A portable, lightweight racer vehicle. The racer includes a body, a motor and a battery powering the motor, a motorized wheel, a first wheel, and a spring-loaded wheel to cause the motorized wheel to maintain contact with a surface upon which the motorized wheel rotates. The first wheel is larger than the motorized wheel and the spring-loaded wheel. A tube section includes a first half section having a pair of interlocking fingers and a pair of notches; and a second half section having a pair of interlocking fingers and a pair of notches. The two halves are removably snap-fit or press-fit together by joining the pair of interlocking fingers of the first half section with the pair of notches of the second half section while simultaneously joining the pair of interlocking fingers of the second half section with the pair of notches of the first half section. A splitter pipe includes a body having an input port and at least two output ports, and a remotely controlled valve between the input port and the at least two output ports. The splitter pipe is non-opaque, and an inner diameter of the input port does not exceed 2 inches.

Provided herein is a set of card-like structure and connector toys for building; the set comprising one or more card-like structures and one or more end cap connectors, wherein the one or more end cap connectors comprise one or more slots for inserting the card-like structures. Also provided herein is a connector toy or a kit of connector toys; comprising one or more slots for inserting card-like structures for building.

Invention Patent for a set of interchangeable blocks, intended to be used as toys, toys for motor development, planning and building skills development toys. The shape of blocks (1, 2, 3, 4, 5, 6, 7 and 8) are based on a cubic shaped block (1), with rounded edges (9), featuringat the edge shared by two adjacent sides (A and B and/or B and C and/or A and C and/or A and D and/or A and E and/or F and B and/or F and C and/or F and D and/or F and E), perpendicularly to the aforementioned sidesat least one narrow slot (10) with a perfect fit for the partial insertion (111) of the locking disc (11); the said cube-shaped block (1) is also offered as a cobblestone-shaped block (2), scalene block (3), bulged triangular block (4), rectangular triangle block (5), trapezoidal block (6), half cube block (7) and portal block (8).

A joint for modular furniture includes a first panel joined to a second panel with a slot and a tab. The slot and tab are formed with complementary faces which are angled to prevent delamination of anisotropic materials such as plywood.
