Abstract

The dual function bicycle air hand pump has functions of bicycle air pump and exerciser. The piston of the dual function bicycle air hand pump has installed a piston which has an off-center threaded canal, which can be closed either by a one-way valve threaded tube and or by a bolt. By simply exchanging the one-way valve threaded tube with a bolt and vice versa, the dual function bicycle air hand pump can be used as a bicycle air pump or an exerciser. When one-way valve threaded tube is used to close the off-center threaded canal of the piston the dual function bicycle air hand pump can be used as an air pump to pump air into a bicycle tire. When a bolt is used to close the off-center threaded canal the dual function bicycle air hand pump can be used as an exerciser for the training of muscles. It is very easy to exchange the one-way valve threaded tube with a bolt and vice versa. There are also subsidiary bullet-shaped adjustable air nozzles which have smaller openings to increase the exercise load for better muscular training.

Number 19 of FIG. 2 is an off center threaded canal. Number 20 of FIG. 2 is one-way valve threaded tube. Number 21 of FIG. 2 is threaded stem of one-way valve threaded tube 20. The threaded stem 21 can screw snugly and tightly into the threaded canal 19. Number 22 of FIG. 2 is one-way valve. Number 23 of FIG. 2 is the canal of one-way valve threaded tube 20. Number 24 of FIG. 2 is a bolt. Number 25 of FIG. 2 is the threaded stem of bolt 24. The threaded stem 25 can screw snugly and tightly onto the threaded canal 19. Number 26 of FIGS. 1 and 2 is the pump cylinder. Number 27 of FIG. 2 is the chamber of pump cylinder 26. The piston with a threaded canal 16 of FIG. 2 can insert snugly and tightly into chamber 27. Number 28 of FIG. 1 is the top threaded end of pump cylinder 26. Number 29 of FIGS. 1 and 2 is the threaded cap. Number 30 of FIG. 2 is the inner thread of the threaded cap 29. Threaded cap 29 can screw snugly onto the top threaded end 28 of FIG. 2. Number 31 of FIGS. 1 and 2 is the central hole of the threaded cap 29. Shaft 14 of FIGS. 1 and 2 can pass through the central hole 31 easily and loosely. Number 32 of FIG. 2 is the bottom threaded end. Number 33 of FIGS. 1 and 2 is the bottom handle with a threaded cap. Number 34 of FIGS. 1 and 2 is the threaded cap of bottom handle with a threaded cap 33. The threaded cap 34 can screw snugly and tightly onto the bottom threaded end 32. Number 35 of FIG. 2 is the threaded connecting tube which is built on the pump cylinder 26 near the bottom threaded end 32 and connects to chamber 27. Number 36 of FIGS. 1 and 2 is an air hose. Number 37 of FIGS. 1 and 2 is the air nozzle. The air nozzle 37 can clip on the air nozzle of bicycle tire. Number 38 of FIGS. 1 and 2 is the threaded connecting nut. Threaded connecting nut 38 is fixed on the air hose 36 and can screw snugly and tightly onto the threaded connecting tube 35. Number 39 of FIG. 2 is the subsidiary bullet-shaped adjusting air nozzle. Number 40 of FIG. 2 is the opening of the subsidiary bullet-shaped adjusting air nozzle 39. The diameter of the opening 40 is smaller than that of the threaded connecting tube 35. Subsidiary bullet-shaped adjusting air nozzle 39 can screw onto the threaded connecting tube 35. Number 41 of FIG. 2 is another subsidiary bullet-shaped adjusting air nozzle. Number 42 of FIG. 2 is the opening of the subsidiary bullet-shaped adjusting air nozzle 41. The diameter of the opening 42 is smaller than that of the opening 40. The subsidiary bullet-shaped adjusting air nozzle 41 can screw onto the threaded connecting tube 35. Number 43 of FIG. 2 is the bottom of the piston with a threaded canal 16. Number 44 of FIG. 2 is the top of piston with a threaded canal 16. Number 45 of FIGS. 1 and 2 is the bottom handle of the bottom handle with a threaded cap 33. Number 10 of FIG. 2 is rubber washer. The rubber washer 10 is inserted inside the threaded cap 34 to secure airtight closure. Number 46 of FIG. 2 is rubber washer. Rubber washer 46 secures airtight closure of one-way valve threaded tube 20 and bolt 24. When one-way valve threaded tube 20 is screwed into the threaded canal 19 from the bottom 43 of piston 16 and then the threaded connecting nut 38 of air hose 36 is screwed onto the threaded connecting tube 35, the dual function bicycle air hand pump 11 can now be used as bicycle air pump. In this case, user clip air nozzle 37 on the air nozzle of bicycle tire first and then steps on the bottom handle 45 with one foot and pull the top handle 13 with one hand or both hands upward to the full extension to open one-way valve 22, and to allow air in the chamber 27 above piston 16 to flow through canal 23 into the chamber 27 below piston 16 to fill it up with air, and then to push the top handle 13 all the way down to close one-way valve 22, and to push air in chamber 27 below piston 16 out through the threaded connecting tube 35, air hose 36, and air nozzle 37 into bicycle tire. When bolt 24 is screwed onto the threaded canal 19 to seal it off and the connecting nut 38 of air hose 36 is detached from the threaded connecting tube 35, the dual function bicycle air hand pump 10 can be used as an exercise air pump. In this case, user grasps the top handle 13 with one hand and bottom handle 45 with another hand to pull them outward all the way to the full extension to suck air into chamber 27 below piston 16 through the threaded connecting tube 35 to produce pulling force and then to squeeze the top handle 13 and the bottom handle 45 inward to push air out of chamber 27 below piston 16, and through the threaded connecting tube 35 to produce resistant force. The air inside pump chamber 27 of cylinder 26 acts as an air spring to produce resistance for the training of body muscles. It is very easy to convert the bicycle air hand pump to an exerciser simply by unscrewing the top threaded cap 29 from the top threaded end 28 and to take piston with a threaded canal 16 out of the chamber 16, and then to replace the one-way valve threaded tube 20 with bolt 24 and vice versa. The subsidiary bullet-shaped adjusting air nozzle 39 or subsidiary bullet-shaped adjusting air nozzle 41 can be screwed onto the threaded connecting tube 35 to decrease air flow and to increase the resistance in order to increase the exercise load for better muscular training.
