A leafless joint apparatus that couples a housing structure to a hatch structure such as a cover or door. Similar to previous hinge apparatuses, the leafless joint apparatus can include a knuckle and a pintel or pin to facilitate pivot operations (e.g., the cover pivoting open). However, the leafless joint apparatus does not rely on leafs that attach by means of fasteners (e.g., screws or the like) and therefore can facilitate sliding operations (e.g., the cover can slide open). Thus, the leafless joint apparatus can facilitate access to an interior of the housing structure by way repositioning the hatch structure via a pivot or hinging operation or via a sliding operation that can partially or fully expose the interior of the housing structure and even, if desired, slide entirely off, decoupling from the housing structure.
