Abstract
The rotating davit apparatus is for fit next to a boat arch. The apparatus is also provided with a modified arch, as desired by the customer. The apparatus is designed to blend into the shape of boat arches, and is thus provided in a plurality of sizes and lift arm angle variations. The apparatus can be used singularly or in pairs, triplet, or as a quad installation wherein 4 apparatuses are mated to the arch. The apparatus provides utility as well as aesthetic appeal. The basic design provides for relatively inexpensive production and sale.
Claims16
A rotating davit apparatus having a hollow single piece lifting arm, the arm for pivotal fit against an existing boat arch, the davit comprising:
- a base for attachment to a boat;
- a rotating plate pivotally attached to the base;
- a winch attached to a top of the rotating plate;
- a hollow aerodynamic one-piece lift arm, the lift arm comprised of a riser and a transverse, the lift arm coincidental with the shape of the boat arch, the lift arm attached to the rotating plate;
- a plurality of pulleys affixed to the lifting arm;
- a cable attached to the winch and passed through the pulleys;
- an attachment device on an end of the cable;
- a connection between the riser and the rotating plate,
- wherein the connection between the riser and the rotating plate further comprises:
- a vertical support attached adjacent to an outer edge of the top of the rotating plate;
- a lower pivot affixed to a top of the vertical support;
- an upper pivot affixed to the riser;
- a link connecting the lower pivot to the upper pivot.
A rotating davit apparatus having a hollow single piece lifting arm, the arm for pivotal fit against an existing boat arch, the davit comprising:
- a base for attachment to a boat;
- a rotating plate pivotally attached to the base;
- a winch attached to a top of the rotating plate;
- a vertical support attached adjacent to an outer edge of the top of the rotating plate;
- a lower pivot affixed to a top of the vertical support;
- a horizontal support attached to the rotating plate, the horizontal support extended from the vertical support across the rotating plate and beyond a side of the plate opposite the vertical support;
- a hollow aerodynamic one-piece lift arm, the lift arm comprised of a riser and a transverse;
- the lift arm coincidental with the shape of the boat arch, the lift arm attached to the horizontal support via an arm pivot;
- the lift arm further comprising:
- an upper pivot affixed to the riser;
- a face for selective fit against the boat arch;
- a taper on a side of the lift arm opposite the face;
- a plurality of pulleys within the lift arm;
- an orifice proximal to an end of the transverse of the lift arm;
- a cable attached to the winch and passed through the orifice of the lift arm;
- an attachment device on an end of the cable;
- a link connecting the upper pivot of the riser to the lower pivot of the vertical support.
A plurality of rotating davit apparatuses, each apparatus having a hollow single piece lifting arm, the arm for pivotal fit against an existing boat arch, each davit comprising:
- a base for attachment to a boat;
- a rotating plate pivotally attached to the base;
- a winch attached to a top of the rotating plate;
- a vertical support attached adjacent to an outer edge of the top of the rotating plate;
- a lower pivot affixed to a top of the vertical support;
- a horizontal support attached to the rotating plate, the horizontal support extended from the vertical support across the rotating plate and beyond a side of the plate opposite the vertical support;
- a hollow aerodynamic one-piece lift arm, the lift arm comprised of a riser and a transverse;
- the lift arm coincidental with the shape of the boat arch, the lift arm attached to the horizontal support via an arm pivot;
- the lift arm further comprising:
- an upper pivot affixed to the riser;
- a face for selective fit against the boat arch;
- a taper on a side of the lift arm opposite the face;
- a plurality of pulleys within the lift arm;
- an orifice proximal to an end of the transverse of the lift arm;
- a cable attached to the winch and passed through the pulleys and the orifice of the lift arm;
- an attachment device on an end of the cable;
- a link connecting the upper pivot of the riser to the lower pivot of the vertical support.
