    • The present invention comprises a base coupled to a water source, the base outputting a stream of water for supporting a toy ball in mid air. The base includes filtering device for substantially eliminating turbulence from the water stream so that it is substantially laminar. The flowing stream contacts a toy ball and lifts it into a position of equilibrium where the upward force of the stream balances the downward force of gravity acting on the ball so that the ball is suspended in mid air. The flowing water clings to the surface of the ball and generates a force tending to center the ball in this supporting stream. If the ball becomes off center, an unequal force on the side of the ball furthest from the center of the stream will force the ball back to the stream center.
    • 本发明包括一个与水源连接的基座,该底座输出用于在中空中支撑玩具球的水流。 底座包括用于基本上消除水流的湍流的过滤装置,使得其基本上是层流的。 流动的流体接触玩具球并将其提升到平衡的位置,在该位置,气流的向上的力平衡作用在球上的向下的重力,使得球悬浮在空中。 流动的水粘附到球的表面,并产生趋于使球在该支撑流中居中的力。 如果球离开中心,则距离球中心最远的一侧的不平等力将迫使球回到流中心。

    • A tennis ball support device is disclosed which is adapted to hold a tennis ball in mid-air without any contact thereof by the blowing of air from underneath. This device includes a housing having side walls being generally cylindrical and a top and bottom. A blower is positioned securely with respect to a mounting platform generally centrally within the housing and the housing defines apertures for receiving and expelling air therefrom. An outlet controlling device is affixed to the upper end of the housing within the outlet aperture to control the distance and speed of upwardly moving air used to support a tennis ball. The devices within the support device are resiliently mounted or insulated with respect to one another such as to minimize sound transmission between parts of the support device to provide a quietly functioning design. Also insulation is used throughout the chamber defined within the housing to further minimize noise and vibration. The height of the ball can be controlled by movement of the outlet control device or a change of shape or design thereof.
    • 公开了一种网球支撑装置,其适于将网球保持在空中,而不会通过从下面吹空气而与其接触。 该装置包括具有大致圆柱形和顶部和底部的侧壁的壳体。 鼓风机相对于通常在壳体中心的安装平台可靠地定位,并且壳体限定用于从其接收和排出空气的孔。 出口控制装置在出口孔内固定在壳体的上端,以控制用于支撑网球的向上移动的空气的距离和速度。 支撑装置内的装置相对于彼此弹性地安装或绝缘,以便最小化支撑装置的部件之间的声音传播,以提供静音功能的设计。 隔离层也用在整个壳体内部,以进一步减少噪音和振动。 球的高度可以通过出口控制装置的移动或其形状或设计的改变来控制。

    • A play device for suspending a floatable object such as a foam plastic ball or a ping pong ball in an air stream and selectively manipulating the direction and position of the air stream so as to move the ball into areas defined by movable structures. The structures are themselves movable when contacted by the air stream to thereby move the ball-receiving areas and increase the difficulty and excitement of the play of the device. The areas may comprise passageways completely through the movable structures or may be the entrances to receptacles in which the ball may be received or may be defined areas adjacent to portions of the structures. The air stream may be provided by a hand-held blower unit which preferrably includes a cradle for the ball. The cradle includes apertures or openings therein which permits the ball to be lifted by the air stream from a starting position in the cradle and suspended in the air stream a substantial distance above the cradle. This permits the ball to be moved relative to the areas without the blower making physical contact with the movable structures which define the areas.The air stream may have a generally constant thrust so as to maintain the ball a generally constant and predetermined distance from the blower unit. Movement of the ball is accomplished by varying the location of the blower unit (i.e. up, down, or to the side) and by varying the orientation of the unit (i.e., its angle or level, front to back and side to side).
    • 一种游泳装置,用于将空气流中的诸如泡沫塑料球或乒乓球之类的可漂浮物体悬浮并选择性地操纵气流的方向和位置,以便将球移动到由可移动结构限定的区域中。 这些结构本身在与气流接触时本身是可移动的,从而移动球接收区域,并增加了装置的播放的难度和兴奋。 这些区域可以包括完全通过可移动结构的通道,或者可以是可以容纳球的容器的入口,或者可以是与结构的部分相邻的限定区域。 空气流可以由优选地包括用于球的支架的手持式鼓风机单元提供。 该支架包括孔或开口,其中球可以通过气流从支架中的起始位置提升,并悬挂在空气流中相当大的距离在支架上方。 这允许球相对于区域移动,而鼓风机与限定区域的可移动结构物理接触。
