Still further, the air/foot pump has certain parts thereof not only providing their intended function in pumping air but also providing the function of generating friction is disclosed.
Claims23
A device for preventing an air pump from sliding down the inside of a saddle post and/or the frame portion in which said saddle support post is mounted in, which comprises:
- a spring, the diameter of said spring being less than the inner diameter of said frame portion and the length of said spring being less than the length of said frame portion, said spring being of the push type spring and having a spring constant k sufficient to push said air pump out of said frame portion, so that when said spring is inserted into said frame portion and an air pump is inserted into said frame portion on top of said spring, said spring pushes a portion of said air pump out of the top of said frame portion each time said saddle support post is removed from said frame portion.
A bicycle air pump which comprises:
- a conventional air pump;
- and
- means for preventing said air pump from sliding down the inside of a saddle support post and/or the frame portion into which said saddle support post slides into, when said air pump is inserted inside said saddle support post and/or said frame portion.
A foot/hand air pump which comprises:
- a round cylinder (70);
- a hollow shaft (72), the outer diameter of said hollow shaft being less than the inner diameter of said cylinder;
- a handle (71);
- means for supporting said handle on one end of said hollow shaft, so that said handle can swivel around said shaft from a vertical position to a horizontal position;
- a piston (76) mounted on the other end of said hollow shaft, said piston fitting inside said cylinder for pumping air therein in one direction thereof;
- an end cap (74) mounted on the one end of said cylinder, said end cap having a hole formed through the center thereof for slidingly receiving said shaft therein and for allowing air to pass therebetween;
- an air outlet portion (75) mounted on the other end of said cylinder, said air outlet portion having a female connector (7c) mounted along a central portion thereof, said air outlet portion having a through hole formed therethrough, said through hole extending from a top surface of said air outlet portion to said female connector, said female connector facing in the radial direction of said cylinder,
- said air outlet portion, said handle supporting means and said end cap having no portion thereof protruding beyond the circumference of said cylinder.
