Abstract:
A ball server comprising:a server seat flatly placed one a ground; a movable rod having a first part in the server seat and a second part out of the server seat, a top of the second part having a ball seat; a bottom of the first part having a buckle plate; and the buckle plate having a first buckle and a driving portion; an elastomer at a bottom of the server seat for ejecting the movable rod upwards; a touch plate pivotally installed at one side of a bottom of the server seat and having a second buckle having a portion within the server seat to be buckled with the first buckle so as to confine an ejecting length of the movable rod; and a delay element in the server seat and having a driving element which is interacted with the driving portion of the buckle plate; the delay element further having a delay unit for delaying an interaction time of the driving portion of the buckle plate and the driving element; and wherein when serving a ball, the movable rod is pressed toward the server seat, then the first buckle of the buckle plate is buckled to the second buckle of the touch plate so that the movable rod is buckled to the touch plate and the driving portion of the buckle plate is in contact with the driving element of the delay element; thereby, the movable rod is interacted with the delay element; when the ball is flatly placed on the ball seat at the top of the movable rod, the elastomer at the bottom of the server seat is stored with a potential energy for ejecting the movable rod; when the ball server is operated, the movable rod is ejected upwards due to the action of the elastomer; by action of the delay element, the movable rod will rise up slowly; when the movable rod is released from the action of the delay element; the movable rod rises up rapidly with being driven by the delay element and thus the ball also rises up; when the movable rod is operated by the delay element, the batter prepares for next beating.
