Abstract
Implementations of slip linkages are shown and described, including two-part and three-part implementations. Implementations of these linkages provide connections between elements with at least one translation degree of freedom, sometimes referred to as a prismatic joint or slider or telescopic joint. Such implementations may be utilized in connection with covers for roll-off containers or dumpsters, such as retractable container covers.
Claims17
A retractable container cover system for a container, comprising:
- a cover configured to be slidingly translated along a length of a top surface of the container between a deployed position and a retracted position;
- one or more slip linkages connected to a first end of the cover;
- a rotatable element connected to the one or more slip linkages;
- a spiral guide adjacent to one end of the rotatable element, the spiral guide configured to receive a side portion of the cover when in the retracted position, wherein the cover comprises a cylindrical terminal portion extending into the spiral guide;
- and
- a yoke connected to the rotatable element comprising a slotted terminal portion engaging the cylindrical terminal portion of the cover to provide one translational degree of freedom;
- and
- wherein the cover is configured to be rolled around the rotatable element when in the retracted position.
