Abstract: A toy capable of combined rotational motion about an axle and translational motion in a vertical direction. Two parallel discs are connected through their centers and are maintained in a spaced-apart position, by an axle. The axle is non-circular in cross-section, and is supported by a tape which is inserted along the axle's longitudinal axis between the two axle-halves. The opposite end of the tape may be attached to a swivel which is in turn connected to a holding apparatus. In order to operate the toy, the end of the tape or the holding apparatus is held in the operator's hand and a down-and-up motion is imparted to the toy. The body of the yo-yo may alternatively be suspended from a string which is firmly anchored to the axle.

The mounting includes slotted pivot mounting holes in a pair of brackets positioned between and above the wing and main frame. A power lift system operated with a hydraulic cylinder utilizes the slotted hole wing mounting system for pivoting the wing through an angle greater than 180 degrees between work position adjacent the main frame and a transportation and storage position over the main frame.

Abstract: The invention relates to a pad for launching toy vehicles whose motors have been previously energized onto a track, comprising a plate provided with an annular runway on which the vehicles are placed, and a turnstile having arms which separate the vehicles and constitute a stop for each of them. A pawl stops the turnstile from rotating. Retraction of this pawl by action on its rod permits, due to the fact that the drive wheels of each vehicle are providing torque, rotation of the turnstile which thus releases the first vehicle. The rotation of the turnstile causes return into blocking position of the pawl whose rod is then extended in a position to be actuated by a vehicle finishing its run on the track. The invention is particularly applicable to games and toys.

Abstract: A vehicle within a ball self-maneuvers to escape obstacles with which confronted, without need for special sensors or programmed response; the vehicle has four wheels, two in front and two behind, but the wheels are of two different tread widths, wider tread widths being one in front and, for example, one diagonally from it at the rear, and similarly narrower tread widths being supplied on the remaining two wheels; relation of the wheel spacing and ball inner diameter prevents more than three wheels from touching the ball at any one time; this, combined with tumbling causing the vehicle to operate upside down at times and initiated by stoppage of the ball at an obstacle, turns the vehicle as it oscillates within the ball and redirects the ball, freeing it from the obstacle.

Abstract: A practice tennis court for practicing serving the tennis balls consists of the complete forward or receiving part of a tennis court back to the net and only the service area beyond the net. Immediately behind the service area is an end net or other backstop to stop the balls without rebounding. At the net, there is a continuous rake extending across the court for sweeping used balls to the back of the service area. At the rear end of the service area adjacent to the collection net is a trough with an endless belt running from side to side to remove the spent balls to a collection point. At the end of use of the court or after play of a selected number of balls, the rake is moved from the net area to sweep the spent balls underneath the collection net and into the trough for removal. A preferred arrangement would provide several of these courts side by side with the collection trough and belt extending across all of the practice courts.
