  • a handle is capable of being fit onto the outside of the tank, when [56] References Cit'ed not used, and used as a handle to operate the piston UNlTED STATES PATENTS q 5974226 1/1898 Temple 417/234 1 Claim, 2 Drawing Figures PUMP PARTICULARLY FOR BICYCLES lower end with a piston sliding inside the cylinder and capable of accommodating the hose, and a handle having an inside diameter and capable of being fit to the outside of the tank and formed like a cup with an open-. ing at one end and mountable detachably to the upper' end of the piston rod.
  • FIG. 1 is an axial cross-sectional view of an air pump, designed in accordance with the present invention, in its operative position; and I FIG. 2' is a partly axial cross-sectional view of the pump, shown in its collapsed position.
  • the present invention relates to a built-up air pump, useful as an air pump, particularly for bicycles, and equipped with a tank 9 and contained compactly for the convenience of transportation, entirely avoiding inconveniences when in its inoperative position.
  • the built-up pump designed in accordance with the present invention comprises a tank 9, which is equipped attachably and detachably, respectively, with a hose 7 on the lower end portion.
  • a cylinder 3 is provided with a check valve 6 on its lower end and disposed inside the tank 9 or fixable extendedly at the upper end of the tank 9.
  • a piston 4 slides inside the cylinder 3 at its lower end.
  • a hollow piston rod 2 is capable of receiving the hose 7, and a handle 1 has an inside diameter which fits the outside diameter of the tank 9 and forms like a cup with an opening at one end and is mounted detachably to the upper end of the piston rod 2.
  • a seal 8 is provided, which is attached to the hollow end formation 12 formed by the lower end of the cylinder 3 and to the inis provided inside with threads of the tank 9 and screwed onto the hollow end portion 12 of the cylinder 3.
  • a spring 14 presses the check valve 6 to its closing position.
  • a seat 5 for fixing the seal is fixed integrally into the hollow end portion 12.
  • the handle 1 is screwed to or mounted by an engaging member to the upper end of the piston rod 2 perpendicularly thereto.
  • the cylinder 3, receiving the piston rod 2 is extendedly connected to the upper end of the tank 9 and the handle 1 is secured to the upper end of the piston rod 2, as shown in FIG. 1.
  • the tank 9 acts as a pressure chamber, facilitating the air pumping operation.
  • this pump is equipped with a tank, when it is not necessary, the cylinder 3 is inserted into the tank 9, the hose 7 is then connected with the hollow piston rod 2, and the handle 1 fitsto the outside face of the tank from above as shown in FIG-2, so that the whole equipment is reduced to a small size slightly longer than the tank 9. Accordingly, the pump is accommodated to a small reduced size, when not in use, thus very convenient for transportation and practically very useful.
  • a pump comprising a tank having removably attached thereto a hose at its free end
  • a cylinder provided with a check valve at its lower end and sealingly received by and axially movable in said tank
  • a hollow cylindrical handle removably secured to the upper free end of said piston rod and having an inner diameter complementary to the outer diameter of said tank, in order to slide said handle in a coaxial arrangement in its inoperative position, and
  • said handle having a substantially cylindrical opening receiving the free end of said piston rod in the inoperative position of said pump.
