The pump head may include a housing defining an aperture sized and shaped to receive a valve head therein; a moveable pin disposed within the housing defining a pin notch disposed about an exterior circumference of the moveable pin; a first taper unit disposed in the housing; a second taper unit disposed in the housing and adjacent to the first taper unit, the second taper unit biased away the first taper unit; and an elastic ring disposed between the first and second taper units, wherein the second taper unit is moveable towards the first taper unit, thereby compressing the elastic ring circumferentially in at least one of two positions, the elastic ring compressed about the pin notch in the first position and about the valve head in the second position.

Abstract: Disclosed are a pressure regulator for reciprocating pumps comprising an audible low pressure blow off and pumps comprising the pressure regulator. Also described is a pump comprising a larger diameter barrel with a higher volume for inflating an inflatable object at a lower pressure and a smaller diameter barrel with a lower volume for inflating an inflatable object at a higher pressure, wherein the pump is switchable to operate using either the larger diameter barrel or the smaller diameter barrel using a single lever attached to an end cap of the smaller diameter barrel.

Abstract: A pump head configured to secure various air valve types is disclosed. The pump head may include a housing and an interior unit sized and shaped to receive a valve head. A moveable pin disposed within the housing coaxially with the first axis may define a pin notch disposed about an exterior circumference of the moveable pin. A first taper unit may be disposed in the housing coaxially with the first axis and coupled to the pin return spring. A second taper unit may be disposed in the housing coaxially with the first axis and adjacent to the first taper unit. An elastic taper C-ring may be disposed between the first and second taper units. The second taper unit is moveable towards the first taper unit, thereby compressing the elastic taper C-ring circumferentially in at least one of two positions, the elastic taper C-ring compressed about the pin notch in the first position and about the valve head in the second position.

Abstract: A bicycling multi-tool with a quicklink removal tool is disclosed. The quicklink tool includes a body having a first prong integral with the body and protruding in a first direction, and a first aperture proximate the first prong. The quicklink removal tool also includes a floating prong base having a second prong integral with the floating prong base and protruding in the first direction. The floating prong base includes a second aperture and a sliding face, and is slideably coupled to the body through a bolt passing through both the first aperture and the second aperture. The bolt is threadedly coupled to at least one of the first aperture and the second aperture. The face of the floating prong base is positioned proximate to and facing a sliding surface of the body. Turning the bolt drives the floating prong towards and away from the first prong.

Abstract: A tire repair tool assembly includes a tool body, at least one tire plug, a plug storage cap, and a hollow tube. The tool body may have a first end and a second end opposite the first end, the tool body having a storage compartment within the tool body, the storage compartment having an opening at the first end. The plug storage cap may be operably coupled to the first end of the tool body. The hollow tube may be sized to receive a first end of the at least one tire plug within the hollow tube, the hollow tube extending from the second end of the tool body and having a tip distal from the second end of the tool body. The tire repair assembly may further include a tool body case having a closed end and an open compartment within the tool body case.

Abstract: A mini pump comprising a linear hand pump assembly and a valve core tool is disclosed. The linear hand pump assembly is configured to operate along a longitudinal pump axis and comprises a first end and a second end opposite the first end. The valve core tool is releasably coupled to the first end and has a central tool axis and a cavity centered on, and running parallel to, the central tool axis. The cavity passes through at least one of a top surface and a bottom surface of the tool and is shaped to mate with a valve core such that, with respect to rotation about the tool axis, the valve core is rotationally fixed to the tool. The pump axis and the tool axis are collinear when the tool is coupled to the assembly. The valve core tool and the pump assembly may be threadedly coupled.
