    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to the drawings, and initially to FIGS. 1-5, a hand pump in accordance with the present invention comprises an outer receptacle 10 including a compartment or chamber 11 formed therein, and including an outlet or mouth 12 formed or provided on one or first end portion 13 thereof for engaging with a needle device 4, such as a game ball needle 40 (FIGS. 1-9), a tire needle 41 (FIGS. 6-9), a life buoy needle 42 (FIGS. 4-9), a balloon needle 43 (FIG. 10), etc., and for suitably inflating various kinds of inflatable objects (not illustrated), such as game balls, blades, balloons, life buoys, tires, etc.
  • A piston 20 is slidably received or engaged in the chamber 11 of the outer receptacle 10 and actuatable or movable relative to the outer receptacle 10 for generating or providing a pressurized air to inflate the inflatable objects (not illustrated), a piston rod 21 is attached to or extended from the piston 20, and a knob or hand grip 30 attached or coupled to the piston rod 21 for moving the piston 20 relative to the outer receptacle 10 and for generating or providing the pressurized air. The piston rod 21 may include a recess or cavity 22 formed therein for weight reducing purposes.
  • The hand grip 30 includes a stud or extension 31 extended downwardly therefrom and attached or coupled to the piston rod 21, and includes a chamber or compartment 32 formed in the hand grip 30, and/or a space 33 formed in the extension 31 of the hand grip 30 and communicating with the compartment 32 of the hand grip 30 for receiving or engaging with or for storing the game ball needle 40 (FIGS. 1-9), the tire needle 41 (FIGS. 6-9), the life buoy needle 42 (FIGS. 4-9), or the balloon needle 43 (FIG. 10) of the needle device 4.
  • The hand grip 30 further includes a peripheral flange or shoulder or engaging member 34 formed or provided thereon for selectively engaging with a cover 35 and for allowing the cover 35 to be detachably or removably attached or mounted to the hand grip 30, and includes one or more reinforcing flanges or ribs or fins 36 extended into the compartment 32 of the hand grip 30 for reinforcing the hand grip 30 and/or for engaging with the cover 35. The cover 35 may be provided for enclosing the compartment 32 of the hand grip 30 and for shielding and protecting the needles 40-43 of the needle device 4.
  • It is preferable, but not necessary that the cover 35 is made or manufactured with a transparent or semi-transparent material or the like for allowing the needle device 4 to be seen through the cover 35. It is to be noted that either of the game ball needle 40, the tire needle 41, the life buoy needle 42, or the balloon needle 43 of the needle device 4 may be selectively used by the user and engaged with the mouth 12 at the one or first end portion 13 of the receptacle 10 for suitably inflating various kinds of inflatable objects.
  • Accordingly, the hand pump in accordance with the present invention includes a needle storing structure or mechanism for receiving and storing various kinds of needles and for easily and quickly and readily inflating various kinds of inflatable objects, such as game balls, balloons, life buoys, tires, etc.
  • Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
