Abstract: An improved kazoo includes a cylindrical input pipe in communication with a downstream plenum for conveying air from the plenum and against a diaphragm traversing the air path. An end cap is secured to the downstream pipe with the diaphragm therebetween. Vents in the end cap expose one side of the diaphragm to the ambient air. An outlet pipe with nuance aperture therein presents an outlet aperture for conveying the back air pressure from the plenum to the ambient air. The kazoo is configured to be encompassed by the user's cupped hands which allows the user to present a mouthpiece in the form of a user's thumb and index finger encircling the input pipe. The size of the inlet, vent, nuance and outlet apertures is controlled by the user's palm and fingers. The controlled size of each aperture allows the user to modulate the aural characteristics of the kazoo sound produced by user air forced into the input pipe aperture.

Abstract: A number of connectors each have a central hub and flexible arms radiating out from the hub, which may interlock orthogonally with other hubs or structural members. A twist in the flexible arms permits axial flexing in addition to the lateral flexing capability in all directions. Distal receiving ends of the flexible arms have laterally expanding and contracting flexible loops, arms, coils, sleeves, cables, or spring-loaded forked arms capable of contracting and expanding from two to ten times the thickness of the flexible arms to accommodate a wide range of sizes of tubes attachable to the flexible arms. Various colors, lengths, and diameters of inexpensive drinking-type straws may connect between connectors to form a wide variety of structural shapes.

Abstract: Described is a child's toy that is useful for assisting a child in imaginative play. The toy of the present invention has two primary embodiments: a sock mounted embodiment and a shoe mounted embodiment. The sock-mounted embodiment comprises a sock and a sock-attachable foot. The shoe-mounted embodiment comprises a shoe harness and a shoe attachable foot. The sock (or shoe) attachable foot is preferably an animal foot (most preferably a pair of feet). Preferably, the sock attachable foot is a replication of a complete foot, but may only be a replication of a top portion of a foot section. The bottom of each sock-attachable foot is designed to attach to a topside of a sock or shoe-attachment harness to be worn, or is simultaneously worn, by a child. There are several preferred sock mounted foot designs, among which are duck's feet, dinosaur feet, monkey feet, chicken feet, monster feet, and the like.

Abstract: A multi-function mobile comprising an elongate, flexible support bar defining opposed first and second end portions. Attached to the support bar is a connector mechanism which is moveable between latched and unlatched positions. The first and second end portions of the support bar are maintained in close proximity to each other when the connector mechanism is in its latched position. Releaseably engageable to the first and second end portions of the support bar is a pliable cover member which is used to maintain the support bar in a substantially ring-like configuration. An elongate engagement strap is releaseably engageable to the connector mechanism when the same is moved to its unlatched position. The engagement strap is sized and configured such that when engaged to the connector mechanism, the first and second end portions are drawn toward each other in a manner causing the support bar to assume a substantially arch-like configuration.

Abstract: A wireless power control system for a motorized toy vehicle which includes a lever mechanism that physically moves a battery into and out of contact with the vehicle motor, thereby enabling selective operation of the toy without the need for electrical wiring. A spring mechanism is used at one end of the battery compartment to contact one terminal of the battery and to the bias the battery into contact with the motor housing, thereby providing electrical contact between one end of the battery and the motor. A rod element is used to contact the spring element and the other terminal of the motor to complete the electrical connection between the battery and the motor. The lever mechanism is selectively used to turn on and off the toy vehicle without the need for electrical wiring or an electrical switch.

Abstract: A pedagogical doll having a body portion in the form of a letter of the alphabet and including a front portion and a back portion, a pair of legs depending flexibly from the body portion, each leg of the pair of legs including a foot portion extending from the leg, a sole surface formed on the bottom of the foot, and a letter of the alphabet formed on the sole surface; wherein each of the legs is movable from at least a forward facing position such that the sole surface is substantially parallel to a front surface of the body portion, to a rearward facing position.

Abstract: A motorized snake includes a chassis having a front end and a rear end with at least one ground contacting drive wheel. A neck is pivotally coupled with the front edge of the chassis to pivot forward and back. A head portion, which includes eyes and an extending tongue, is pivotally connected to the front portion of the neck.

Abstract: A bubble ring is comprised of a tubular wall with a height which is greater than its wall thickness. The wall is parallel to the axis of the ring for reducing resistance to airflow along the axis of the ring. Plates extend radially from the inside and outside surfaces of the ring for holding a bubble solution by surface tension and capillary action. The gaps between the plates are generally evenly wide throughout for evenly holding bubble solution. The gaps also have open front and rear ends aligned with the axis of the ring for better releasing solution. Through holes are arranged in the wall parallel to the axis of the ring for holding and releasing additional solution. A handle is hinged to the ring. The handle is pivoted across the ring for shipping, and pivoted outward for use.

All these modeled parts are connected to one another through engagement of slits provided thereon and thereby form a three-dimensional toy octopus. These parts are also provided with patterns showing specific features that are usually found on a real octopus, so that the assembled toy octopus is vivid to attract more players and helps players to know more things about the octopus.

Abstract: A system and method for providing a visible marker when at least two objects are combined. The visible marker may be any desired marking but, in the preferred embodiment, is a heart-shape. The two objects may be two-dimensional, such as cards, or three-dimensional, such as toys or household items. The creation of the visible marker by bringing two objects into proximity can show common origin and manufacture and, where a heart-shape is used, can send positive social and moral messages of love and togetherness.

Abstract: A cartridge ejecting control mechanism for toy revolver, comprising of a cartridge inserting rubber seat, a cartridge inserting rubber, a cartridge clasp track, a cartridge clasp, a cartridge track, an ejector, a cartridge track spring and a cartridge track cover, which are sequentially installed in each cartridge hole of a cartridge unit to be loaded into the cylinder of a toy revolver, before a cartridge unit cover is fitted to the rear end. In such a mechanism, each cartridge of the cartridge unit can be loaded with a plurality of shots. When each time the trigger is pressed, gas pushes the cartridge clasp forward to clasp the second shot while the first shot is fired. After the firing process, the resiliency of the cartridge clasp will push the second cartridge to the cartridge inserting rubber; to the effect that only one shot is fired at a time until all shots are fired from the cartridges when reloading is required.

The wheel-mounting base comprises a compartment that is delimited by two sidewalls having aligned axle holes. The axle extends through the axle holes of the wheel-mounting base and an axle hole of the wheel received in the compartment. The fixing members are respectively mounted to the sidewalls of the wheel-mounting base. Each fixing member comprises an axle-receiving hole for securely engaging with an associated one of the ends of the axle. Each fixing member is movable between a first angular position in which the fixing member is disengagable from an associated one of the sidewalls of the wheel-mounting base and a second angular position in which the fixing member is securely engaged with the associated one of the sidewalls of the wheel-mounting base.
