A multi system of structures is disclosed that is readily collapsible and rolled into flat package which can be readily stored in a closet, backpack, or carried. When desired to be set up you roll out a mat. The automatic spring hinges detach and the multi structure system expands ready for imaginary play with small toys or figures. The structures comprise of a canvas like membrane structures with pre-installed spring hinges and levers the canvas structures are mounted to the spring hinges that inherent tension in the spring hinge combined with levers automatically expand the structures into a fully erect positions. The structures can be moved around on the mat with hook and loop fasteners on the bottom of the structures.

An aeronautical vehicle that rights itself from an inverted state to an upright state has a self-righting frame assembly has a protrusion extending upwardly from a central vertical axis. The protrusion provides an initial instability to begin a self-righting process when the aeronautical vehicle is inverted on a surface. A propulsion system, such as rotor driven by a motor can be mounted in a central void of the self-righting frame assembly and oriented to provide a lifting force. A power supply is mounted in the central void of the self-righting frame assembly and operationally connected to the at least one rotor for rotatably powering the rotor. An electronics assembly is also mounted in the central void of the self-righting frame for receiving remote control commands and is communicatively interconnected to the power supply for remotely controlling the aeronautical vehicle to take off, to fly, and to land on a surface.

A method is provided for designing a garment having a plurality of surfaces. The method includes selecting at least one surface from the plurality of surfaces to serve as a tactile stimulating surface. The method further includes selecting a texture for the at least one surface, different from that of at least a majority of the plurality of surfaces, configured to provide tactile stimulation to a touch sensing organ.

Apparatus (2) for providing an animated image for a viewer, which apparatus comprises: (i) a device (4, 6, 10, 12) for providing the animated image; and (ii) securing means (14) for securing the apparatus (2) to a part (16) of a structure (18) such that the apparatus (2) is fixed with respect to the structure (18), and such that the device (4, 6, 10, 12) is operable by the viewer in order for the viewer to see the animated image.

A storage-size-adjustable play tunnel for children includes a supporting frame constituting a tunnel structure, and a cloth cover. End openings at two sides of the tunnel structure communicate each other. The supporting frame is formed by bending a spring steel wire. The spring steel wire is bent to form a plurality of continuous loop parts. Both ends of the spring steel wire are provided with a locking mechanism. By means of the locking mechanism, the two ends of the spring steel wire can integrally slide along the spring steel wire and be fastened onto any positions of the spring steel wire. With sliding of the two ends of the spring steel wire, the supporting frame is adjustable in a radial direction as a whole.

A weighted lap pad comprising a base having a body-conforming configuration adapted to be placed across a lap of a seated user, the base having a plurality of channels having weights permanently enclosed within respective channels, the weights having a cumulative weight of greater than 2 pounds and a transparent window positioned at a surface of the base and in part defining a device pocket configured to receive a paper device or electronic touch screen device. The transparent window and associated pocket allowing a user to experience visual and multi-media sensation while simultaneously receiving tactile sensation of the weighted pad. The electronic device also allows for a variety of user control and sensory feedback options.

The present disclosure provides a stress-relief folding ball, including a folding ball main body capable of extending and shrinking, wherein the folding ball main body includes a folding matrix, folding lines, folding walls, pressing spherical surfaces and an accommodating cavity; the folding matrix is arranged in a middle of the folding ball main body, the folding lines and the folding walls are arranged at left and right sides of the folding matrix, the folding lines and the folding walls are alternately connected, the pressing spherical surfaces are arranged at left and right ends of the folding ball main body. The folding ball main body provided by the present disclosure is an integrally formed structure and not easy to be damaged, thereby reducing the purchasing cost. The selected material is the non-metal elastic material, which may increase the comfort and enjoyment during use.

A transformable toy including a main body and a transformation inducing unit, wherein the main boy includes a body part; at least one first body portion; at least one pressing part; and a locking part to fix the body part and the first body portion to the main body. When the locking part is unlocked by an operation of the transformation inducing unit, the first body portion and the one pressing part are moved away from the body part such that the toy transforms from a first shape into a second shape in which at least a portion of the main body is caused to be floating from a floor by the pressing part.

Provided herein is a string shooting device having a string capable of generating lift when propelled from the string shooting device and a guide to readily attach and detach the string from the string shooting device. A string shooting device described herein includes: a body; a housing attached to the body; a pair of wheels, where at least one of the pair of wheels is a driven wheel; and a string, where the string includes a surface texture configured to increase air friction in response to the string being propelled through the air by the pair of wheels. The string of an example embodiment defines an axis along which the string extends, and where the string includes a plurality of fibers extending away from the axis.
