Abstract

A pump that includes a body having a base and a top portion, wherein the base is configured to be anchored to the ground and the top portion is detachably connected to an upper plate in the body. The pump includes a handle assembly including a piston rod, handle bar, and cap that are detachably connected to each other by a fastener. The pump includes a tube positioned in the body. The tube slidably receives the piston rod and is connected to an air line. A hose is connected to the air line and extends from the body. The hose has a head configured to engage the nozzle of a tire. When the piston rod is moved downward within the tube, air is displaced from the tube and through the air line to the hose such that the head dispenses air.

First claim

The invention claimed is:

1. A pump for inflating tires with air, comprising:
a body having a base and a top portion, wherein the base is configured to be anchored to the ground and the top portion is detachably connected by a first fastener to an arm having a hole that is located in the body and proximate a top end of the body;
a handle assembly including a piston rod and a handle bar;
a tube positioned in the body and supported by an upper plate in the body and a lower plate in the body, wherein the upper plate and lower plate extend from an interior wall of the body, the tube receiving the piston rod such that a piston mounted on the piston rod slides in the tube and the tube being connected to an air line via a fitting extending from below the lower plate into a gap between the lower plate and the base, wherein the air line includes a flexible tube and extends from the fitting to an adapter located above the upper plate; and
a hose connected to the air line via the adapter and extending from the body, the hose having a head configured to engage a nozzle of a tire;
wherein, when the piston rod is moved downward within the tube, air is displaced from the tube and through the air line to the hose such that the head dispenses air.

2. The pump of claim 1 , further comprising a pressure gauge.

3. The pump of claim 1 , wherein the air line comprises (a) a first air line portion that is connected at a first end to a barbed fitting extending from the tube and that is connected at a second end to a check valve and (b) a second air line portion that is connected at another first end to the check valve and that is connected at another second end to the adapter connected to the hose.

4. The pump of claim 1 , wherein the hose is threadably connected to the adapter that is connected to the air line.

5. The pump of claim 4 , wherein a portion of the hose is made of threaded metal.

6. The pump of claim 1 , wherein the piston includes two flexible gaskets that each form a seal with an interior wall of the tube.

7. The pump of claim 1 , wherein the body, handle bar, piston rod, and tube are each made of either steel or aluminum.

8. The pump of claim 1 , wherein the handle assembly includes rubber grips that are slidably mounted to the handle bar.

9. The pump of claim 1 , wherein the body is open at a bottom end thereof to provide access to the tube inside the body prior to the body being anchored to the ground or upon detachment of the body after having been anchored to the ground.

10. The pump of claim 1 , wherein the head magnetically connects to the body.

11. The pump of claim 1 , wherein the tube rests on the lower plate.

12. The pump of claim 1 , wherein the top portion is circular plate.
