Ball game practice apparatus

#1. FIELD OF THE INVENTION

#The present invention relates to a ball game practice apparatus comprising a ball downwardly supported at a lower end of a dangling elastic expanding member and a practice board having a rebounding board at a front face thereof.

#2. DESCRIPTION OF THE PRIOR ART

#The accompanying drawings show preferred embodiments of a ball game practice apparatus related to the present invention; in which,

#FIG. 1 is a principle construction view,

#FIG. 2 is a perspective view showing an overall construction,

#Preferred embodiments of a ball game practice apparatus for use e.g. as a tennis practice apparatus will be particularly described hereinafter with reference to the accompanying drawings.

#As shown in FIG. 1 which illustrates a basic construction embodying the principle of the present invention, when a ball 4 suspended centrally in the same figure is hit by a player's racket, a dangling elastic expansing member 3 is expanded and at the same time an elongate lateral elastic expanding member 2 disposed along a frame 1 is also expanded. Chain lines in the this figure illustrate conditions in which these expanding members are expanded to their maximum extents. When the ball 4 is hit towards a practice board, a line segment ratio BD/BC is considerably larger than a line segment ratio AD/AC and an angle .alpha. of the line segment AD relative to the horizontal line is considerably larger than an angle .beta. of the line segment BD relative to the same.

#That is to say, the line segment portion BD of the elastic expanding member 2 along the frame 1 is sufficiently expanded thereby providing sufficient returning force to the ball 4. Therefore, the ball 4 rebounding from a rebounding board of the practice board has a variety of rebounding forces and angles but always returns to the vicinity of the position where the ball is originally hit. Since the horizontal returning force is sufficiently larger than the vertical returning force, the rebounding ball 4 may return to the original hit position substantially horizontally.
