Abstract
There is provided in a preferred embodiment of the present invention a maintenance device having a lubricant reservoir attached to the upper end of a fixed body, and a dynamic body that is slidably engaged and disposed within the fixed body at the lower end thereof. Attached to the base of dynamic body is a trio of cleaning arms. A spring that is internally positioned between the dynamic body and the fixed body biases the dynamic body downward and the cleaning arms to a relaxed position. As the dynamic body retracts upon the application of force by a user, lubricant is released and pumped from the lubricant reservoir and each of the cleaning arms pivot and engage the side wall of the male connector.
Claims18
A maintenance device for a fastener, comprising:
- fixed body having an interior and an upper end and a lower end;
- a lubricant reservoir, said lubricant reservoir positioned at said upper end of said fixed body;
- a first valve at an opening of said lubricant reservoir, said first valve adapted to alternate between a closed position and an open position to release lubricant from said lubricant reservoir when said valve is in said open position;
- a metallic cleaning surface positioned at said lower end of said fixed body, said cleaning surface being sized to engage and clean an exterior surface of a male connector of said fastener;
- and
- a dynamic body positioned at said lower end of said fixed body and a first biasing spring positioned between said dynamic body and said fixed body, wherein when said dynamic body is pressed against said first biasing spring and said first biasing spring is compressed, said cleaning arms pivot to a closed position.
A maintenance device for a fastener, comprising:
- fixed body having an interior and an upper end and a lower end;
- a lubricant reservoir, said lubricant reservoir attached to said upper end of said fixed body;
- an abrasive block positioned on said lubricant reservoir;
- a dynamic body having an interior drum, said dynamic body positioned within said fixed body;
- a first biasing spring positioned between said fixed body and said dynamic body, said first biasing spring biasing said dynamic body in a downward direction;
- and
- a cleaning surface adapted to engage a male connector of said fastener, said cleaning surface being connected to said dynamic body;
- wherein when said dynamic body is pressed against said first biasing spring and said first biasing spring is compressed, said cleaning surface engages said fastener.
A maintenance device for a fastener, comprising:
- a lubricant reservoir having an opening;
- a first valve positioned at said opening of said lubricant reservoir;
- a dynamic body positioned exterior of said lubricant reservoir to force said first value to release lubricant from said lubricant reservoir, said dynamic body having an interior having a drum disposed therein;
- a cleaning surface connected to said dynamic body;
- wherein when said dynamic body causes said first valve to release lubricant, lubricant flows through said dynamic body onto said cleaning surface.
