Abstract
A davit used for abseiling purposes and adapted to anchor to a parapet roof includes a davit base assembly and a mast base assembly associated with a mast and configured to rotation about the davit base assembly. The davit base assembly includes a mounting plate sub-assembly adapted to anchor to the roof, and a removable base sub-assembly configured to cooperate with the mounting plate sub-assembly. The mast base assembly includes a roller bearing arrangement configured for contact with a sleeve of the removable base sub-assembly during rotation of the mast and the associated mast base assembly about the davit base assembly.
Claims20
A davit, comprising:
- a davit base assembly comprising:
- a removable base sub-assembly including securement means configured to cooperate with the mounting plate sub-assembly wherein sliding movement of the removable base sub-assembly in a linear action effects movement of the securement means into an engaged position for securement of the removable base sub-assembly to the mounting plate sub-assembly, said securement means configured wherein sliding movement of said base sub-assembly in a reciprocal linear action effects movement of said securement means into a disengaged position where the removable base sub-assembly is released for removal from the mounting plate sub-assembly;
- and
- a mast base assembly associated with a mast and configured for rotation about the davit base assembly, said mast base assembly including a roller bearing arrangement configured for contact with a sleeve of the removable base sub-assembly during rotation of the mast and the associated mast base assembly about the davit base assembly.
A davit and mast base assembly, comprising:
- a davit base assembly adapted to anchor to a roof;
- and
- a mast base assembly associated with a mast and configured for rotation about the davit base assembly, said mast base assembly including an external bearing arrangement configured for contact with an outer-facing surface of a sleeve of the davit base assembly during rotation of the mast and the associated mast base assembly about the davit base assembly.
A davit and mast base assembly, comprising:
- a davit base assembly adapted to anchor to a roof;
- and
- a mast base assembly associated with a mast and configured for rotation about the davit base assembly, said mast base assembly including an internal roller bearing sub-assembly configured for rolling contact with an inner-facing surface of a sleeve of the davit base assembly during rotation of the mast and the associated mast base assembly about the davit base assembly.
