Abstract
A pump includes a cylinder, a handle, a piston rod connected with the handle at an upper end and connected with a piston at a lower end, a flexible tube communicated with the cylinder, a nozzle communicated with the flexible tube, a first holding element installed on the cylinder in order to hold the flexible tube and a second holding element installed on one of the handle in order to hold the flexible tube.
Claims4
A pump comprising:
- a cylinder;
- a handle;
- a piston rod connected with the handle at an upper end and connected with a piston at a lower end, with the piston slideable in the cylinder, with the handle extending generally perpendicular to the piston rod, with the handle and the piston rod and the cylinder forming a generally T-shape, with the piston rod, handle and piston moveable from a not-in-use position, with the handle in the not-in-use position being adjacent to the cylinder and having increasing spacing from the cylinder when moved from the not-in-use position;
- a flexible tube connected and in fluidal communication with the cylinder at a first end;
- a nozzle communicated with the flexible tube opposite to the first end;
- a first holding element installed on the cylinder;
- and
- a second holding element installed on the handle adjacent to the upper end of the piston rod, with the first holding element being spaced from and intermediate the first end of the flexible tube and the second holding element, with the flexible tube extending from the first end and over the second holding element, with the first holding element of a size slideably receiving the flexible tube adjacent to the nozzle, with the size of the first holding element preventing slideable passage of the nozzle, with the flexible hose being a length from the first end equal to a spacing of the second holding element from the first end plus a spacing of the second holding element from the first holding element when the handle is in the not-in-use position to hold the handle in the not-in-use position.
