Abstract
An inflatable sports ball and its pneumatic inflation valve core are provided. The pneumatic inflation valve core includes a passage penetrating the pneumatic inflation valve core in a lengthwise direction. The passage is provided for receiving an inflation needle which is served for inflating a ball bladder of an inflatable sports ball. When an inflation needle inserts into the passage of the pneumatic inflation valve core, since the pneumatic inflation valve core has adequate length, the pneumatic inflation valve core prevents the inflation needle from piercing through the ball bladder as the ball bladder is flat.
Claims20
A pneumatic inflation valve core of an inflatable sports ball, which includes an exterior cover, a ball bladder disposed in the exterior cover, and a valve housing arranged on the inner surface of the ball bladder for fixing the pneumatic inflation valve core therein, the pneumatic inflation valve core comprising:
- a lengthwise body having a passage penetrating the lengthwise body in a lengthwise direction;
- a mouth disposed on one end of the lengthwise body and the distal surface of the mouth is exposed on the exterior cover;
- a sheath disposed on the other end of the lengthwise body opposite to the mouth, and extending outwards the valve housing thereof in the ball bladder;
- and
- a crown disposed between the mouth and the sheath, and served for being fixed in the valve housing,
- wherein when an inflation needle inserts into the passage of the pneumatic inflation valve core, the pneumatic inflation valve core has adequate length such that the sheath prevents the inflation needle from piercing through the ball bladder as the ball bladder is flat.
An inflatable sports ball, comprising:
- an exterior cover having an opening thereon;
- a ball bladder disposed in the exterior cover, and having an opening thereon aligned to the opening of the exterior cover;
- a valve housing arranged on the inner surface of the ball bladder, corresponding to the opening of the ball bladder, and having a cavity penetrated through the valve housing;
- an pneumatic inflation valve core inserted and fixed in the cavity, having a passage penetrating through the pneumatic inflation valve core in a lengthwise direction for receiving an inflation needle,
- wherein, when an inflation needle inserts into the passage of the pneumatic inflation valve core, the pneumatic inflation valve core has adequate length so as to prevent the inflation needle from piercing through the ball bladder as the ball bladder is flat.
