  • Patent number: 9616275
    Abstract: An ankle strengthening and rehabilitation exercise device is disclosed. The device is intuitive and simple to use by a patient even without professional medical supervision since the device indicates a specific movement of a foot by pivoting an ankle of the patient. In particular, the device may have an extension member that can be positioned on a frame of the device. The foot of the patient may engage the device. An elastic member may be secured to the extension member and the foot. The direction of the elastic member indicates the direction the foot of the patient should move by pivoting his or her ankle to specifically work or strengthen and exercise a particular ankle muscle of the patient.

    Abstract: A word game playing piece having at least one gravity-stable playing position, at least one gravity-unstable playing position, and a holder that supports the playing piece in its gravity-unstable position. The playing piece is provided with word game indicia, concealed when the playing piece is in its gravity-stable playing position, and revealed when the playing piece is supported in its gravity-unstable playing position by the holder. The player piece is automatically self-righting from gravity-unstable to gravity-stable position to minimize the exposure of its indicia to view.

  • Patent number: 5100360
    Abstract: A toy includes a tiltable structure having a generally flat surface and an upstanding rim disposed about the periphery of the flat surface, an inverted cup-like member having an open bottom, and a ball disposed partially within the cup-like member and partially therebelow. The ball is configured for free rolling motion over the flat surface within the confines of the upstanding rim when the flat surface is tilted relative to the horizontal. The ball is dimensioned to continuously support at least some portion of the bottom of the cup-like member spaced above the flat surface, whereby movement of the ball over the flat surface carries with it the cup-like member which moves over the flat surface with a wobbling sliding movement.

  • Patent number: 4931029
    Abstract: Th present invention is related to a modification made on a regular toy tumbler to let the toy tumbler be equipped with a sound generating IC controlled by a plate spring type microswitch. When the toy tumbler stands still, the microswitch is OFF, and no sound is generated. When the toy tumbler is rocking, the microswitch is ON, and the sound generating IC is triggered to provide audio signal through an electronic speaker. Matching with the innovative outer appearance, the toy tumbler is bestowed with a new life.

  • Patent number: 4869503
    Abstract: The game utilizes free-standing game pieces to enhance a player's options when there are a less than a desirable number of participants for a traditional field game. Each of the game pieces is composed of a lightweight material for easy positioning. The game pieces are large enough to serve as both a target and an obstacle. The game pieces are also constructed with a flexible support means to both cushion contact with a human player or the game object and lessen the possibility of the game pieces breaking upon such contact. The game pieces are connected to a base that disconnects upon contact capable of breaking the support means. Rules for use of the game pieces are also disclosed.

  • Patent number: 4767376
    Abstract: A self-righting flywheel motor operated toy vehicle includes attitude restoration components at the rear thereof, the vehicle having the center of gravity thereof along the longitudinal centerline thereof. A first component includes an attitude restoration plate configured in the form of a spoiler member attached at the rear of the vehicle above the rear wheels and having a width greater than the distance between the outer sides of the wheels for enabling the maintaining of a slight elevational angle of the vehicle when on either side, with a corner of the driving wheel on that side in contact with the surface. The force of the driving wheel tends to self-right the vehicle.
