Abstract
Push On and Pull Off Schrader and Presta Valve Air Filler Pump Head is disclosed. By using a simple sliding motion and a complete redesign on how the nozzle engages the valve, the invention takes into account the natural action of a hand performing the action where the fingers would naturally be especially in a tight space like that of one that could be encountered between spokes. The invention also takes advantage of dominant muscle groups in the hand and fingers to make the motion of valve engagement and disengagement easier.
Claims20
A pump head comprising a thumb press, a collet guide, a center mounted fastener screw, a plurality of side mounted fastener screws, a collet ring, a pressure fitting, and a spring;
- where the collet guide has a top portion, an opposing bottom portion, and a length;
- where the thumb press is fastened to the top portion of the collet guide using the center mounted screw and the plurality of side mounted fastener screws;
- where the collet ring slides over the collet guide, and where the collet ring slides along the length of the collet guide;
- where the spring is around the collet guide, and where the spring provides a force to separate the thumb press and the collet ring;
- and
- where the pressure fitting resides within the collet guide.
A method for inflating a sealed body comprising the steps of:
- grasping a pump head by placing a thumb on a thumb press and two fingers on a sliding collet ring, where the pump head comprises the thumb press, a collet guide, the collet ring, a pressure fitting, and a spring, where the collet ring slides over the collet guide, where the collet ring slides along the length of the collet guide, where the spring is around the collet guide, where the spring provides a force to separate the thumb press and the collet ring, and where the pressure fitting resides within the collet guide;
- squeezing the collet ring towards the thumb press thereby causing the collet ring to slide along the collet guide and the spring to compress;
- placing the pump head over a valve of the sealed body;
- and
- releasing the collet ring thereby causing the spring to decompress and the collet ring to slide along the collet guide to secure the pump head to the valve.
A pump head comprising a thumb press, a collet guide, a center mounted fastener screw, a plurality of side mounted fastener screws, a collet ring, and a pressure fitting;
- where the collet guide has a top portion, an opposing bottom portion, and a length;
- where the thumb press is fastened to the top portion of the collet guide using the center mounted screw and the plurality of side mounted fastener screws;
- where the collet ring slides over the collet guide, and where the collet ring slides along the length of the collet guide;
- and
- where the pressure fitting resides within the collet guide.
