Abstract
A hand pump has a tubular pump housing with a longitudinal axis. A piston with a peripheral seal reciprocates along the axis to compress air against a sealed end of the housing. A tubular plunger nested in the housing connects to the piston to reciprocate the piston and compress the air. A flexible hose is placed in fluid communication with the compressed air. The hose is coiled to fit entirely within the tubular plunger during storage. A removable handle is inserted through a distal end of the plunger to make it easier to reciprocate the plunger. The handle, tire repair tools and materials, and other items can be placed inside the plunger for storage, and enclosed by placing an end cap on the pump housing.
Claims15
A pneumatic hand pump capable of providing a relatively large volume of air during a single stroke for inflating an All Terrain Vehicle tire, comprising:
- a cylindrical, tubular pump housing having a diameter of about two inches, a longitudinal axis with a length of about ten inches, and a base at one end of the pump housing;
- a piston sized to reciprocate along the axis;
- a seal interposed between the piston and the housing to seal the piston against the housing and to form a variable volume chamber to compress air in the chamber as the piston moves toward the base;
- a plunger having a distal end comprising a piston, said plunger and piston adapted to slidably reciprocate in the pump housing, the plunger being slightly less than 2 inches in diameter and slightly less than 10 inches in length to create a storage space therein;
- and
- a coiled flexible hose having a front end connected to the piston inside the housing and placed in fluid communication with the variable volume chamber, the hose having an opposing second end placeable outside the housing, the hose being coiled to fit entirely within the plunger when in a stored configuration, said hose having sufficient physical memory that it recoils inside the plunger after use.
A hand pump capable of providing a relatively large volume of compressed air, and having sufficient storage space for storing tools comprising:
- a tubular, cylindrical housing into which is placed a sliding piston to compress air between the piston and a sealed end of the housing as the piston moves toward the sealed end of the housing, the housing having an opposing end, the piston having a seal interposed between the piston and the housing to seal the piston while compressing the air;
- a plunger inside the housing and having an interior end connected to the sliding piston to reciprocate the piston in the housing and compress the air, the plunger having an opposing, distal end;
- a hose having an interior end inside the housing and placed in fluid communication with the compressed air when the hose is in use, the hose having a distal end from which the compressed air exits, the hose being placeable entirely inside the housing during storage, said hose having sufficient physical memory that it re-coils after use;
- a handle removably connected to the distal end of the plunger to actuate the plunger and pump the air;
- and
- an end cap removably connected to the distal end of the housing to enclose the housing with the hose inside the housing.
