A plate connecting assembly according to an embodiment includes a first frame, with an upper portion and a lower portion of the first frame making a predetermined angle with each other, and a second frame having a first support portion facing the upper portion and a second support portion facing the lower portion. In the plate connecting assembly, a first fixation-subject object is fixed between the upper portion and the first support portion, a second fixation-subject is fixed between the lower portion and the second support portion, and thus the first and second fixation-subject objects are fixed in such a manner that an angle therebetween is the same as an angle that the upper portion and the lower portion make with each other.

A 3D fort building kit is a device that can create a variety of structures and shapes. In other words, the device has improved materials and designs with better qualities, that enables kids to build complex 3D structures. To accomplish this, the device includes panels, connectors and utility features that help kids to construct and assemble a structure of their choice in many designs. Further, structures may be constructed in many creative designs by allowing the panels to be connected vertically, horizontally, and at any angle. Furthermore, the constructed structures can be disassembled and constructed again to build other designs safely by kids. Additionally, the device is simple, durable, and light weight enough for young kids to build stable and versatile structures of their choice.

A modular construction kit includes modular construction blocks, each includes at least one interface face. 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 magnetic plate toy includes a first plate, a second plate, and a connector. The first plate and the second plate are disposed to oppose each other. The connector extends in an opposing direction of the first plate and the second plate and connects the first plate and the second plate to each other. The first plate includes a first plate member and a plurality of first magnets provided inside the first plate member. The second plate includes a second plate member and a plurality of second magnets provided inside the second plate member to correspond to the plurality of first magnets. The second plate is connected to the connector to be rotatable around the opposing direction as a rotation axis direction.

The present invention refers to a system of interchangeable connection, comprising one or more connectors (100), with variable configurations and angles, which have two or more circular (50) and/or oblong (60) holes in their surfaces for fixation of plastic bottles (500) in a “nut-thread” or “cap-bottle” way. In addition, the present invention addresses the use of the system for interchangeable connection for functional and/or creative purposes in the process of reusing plastic bottles (500) in a simple and practical way.

The subject matter of this specification can be embodied in, among other things, a modular vehicle that includes a vehicle body defining a seat space that is at least partially enclosed and defines an interior volume to contain one or more character figures, a first character seat assembly removably mountable to the vehicle body within the seat space as a first simulated seat, and a second character seat assembly removably mountable to the vehicle body within the seat space as a second simulated seat that is sized differently from the first simulated seat such that the second character seat assembly is prevented from removably mounting to the vehicle body within the seat space when the first character seat assembly is removably mounted to the vehicle body within the seat space.

A device for cutting and bending a hollow elongate tube. A measuring subassembly is adapted for measuring a desired size of the tube. A cutting subassembly is adapted for cutting the tube to the desired size. A bending subassembly is adapted for bending the cut tube to a desired angular orientation. The bending subassembly includes a base controlling a radius of a bend to be formed in the cut hollow elongate tube, and a user grippable handle. The user grippable handle is configured to enable a user to rotate the cut hollow elongate tube, relative to the round base, to form the bend in the cut hollow elongate tube.

According to one embodiment, a modular toy assembly system featuring one or more bases and a plurality of posts. Coupled to recessed connectors of the base, the plurality of posts includes a first end connector and a second end connector for coupling to different bases to provide depth of the toy. The posts include a first elongated body element and a second elongated body element interposed and extending between the first end connector and the second end connector. The first elongated body element and the second elongated body element are oriented to produce (i) a first slot between a first side of first elongated body element and a first side of the second elongated body element and (ii) a second slot between a second side of first elongated body element and a second side of the second elongated body element.

The present invention relates to a novel activity board device. The device is designed to keep a child occupied, entertained, and happy while in a car, playing at home, in a restaurant, etc. Specifically, the portable activity board device comprises attachable toys and accessories. The activity board device can be secured around the headrest of a vehicle or placed on a flat surface for play.
