The present invention generally relates to flagpole winches and cleats, and specifically to a flagpole winch or cleat mounted internally to a flagpole.
Flags are displayed for many different reasons, on many different occasions and in many different ways. In some situations, such as when the flagpole is inaccessible, it is desirable to use a flagpole in which the flag can be raised and lowered using winches and so forth. Various types of flagpoles have been developed.
It is often desirable to substantially eliminate exposed halyard, especially while the flag is flying. There are flagpole assemblies in which the halyard remains substantially concealed from view but allows the flag to be raised and lowered. The flagpole assembly includes a hollow pole mounted at its base to a support. A first end of a halyard is connected to a winch. The winch is typically mounted near the base of the pole. The halyard passes through the hollow pole and out an exit opening at the pole tip.
Paying out the halyard from the winch causes the flag to lower as the length of the halyard extending from the exit opening in the hollow pole increases. The halyard is retracted by winding the halyard onto the winch. If the halyard has a flag attached to it, the flag is raised by this operation. If not, substantially the entire halyard is housed within the hollow pole or on the halyard winch.
A primary advantage of this design is that it simplifies raising and lowering of a flag while keeping the halyard substantially concealed. Keeping the halyard substantially concealed reduces the deterioration of the halyard by preventing its exposure to the elements. It also eliminates problems caused by tangled halyards and flags.
In a first embodiment, the present invention is a flagpole assembly incorporating a flagpole body, an internal fastening plate, an external fastening plate, and at least one threaded fastener.
The flagpole body is generally-cylindrical and hollow, having a first end, a second end, a principal axis, an inner surface, an outer surface and an aperture disposed in the side thereof. The aperture passes from the inner surface to the outer surface along a radial axis substantially orthogonal to the principal axis. At least one internal fastener passage passes from the inner surface to the outer surface.
The internal fastening plate is disposed at least partly within the flagpole body, and has an inner surface, an outer surface, an aperture disposed therein and at least one threaded fastening hole generally aligned to an internal fastener passage in the flagpole body. The external fastening plate is disposed at least partly outside of the flagpole body, and has an inner surface, an outer surface, an aperture disposed therein and at least one external fastener passage generally aligned to an internal fastener passage in the flagpole body. The threaded fastener is disposed partly within an external fastener passage, partly within an internal fastener passage and partly within a threaded fastening hole.
In a second embodiment, the present invention is a flagpole assembly including a flagpole body, an internal fastening plate, an external fastening plate, at least two threaded fasteners and a winch mount.
The generally-cylindrical, hollow flagpole body has a first end, a second end, a principal axis, an inner surface, an outer surface, an aperture disposed in the side thereof, passing from the inner surface to the outer surface along a radial axis substantially orthogonal to the principal axis. The flagpole body includes at least two internal fastener passages passing from the inner surface to the outer surface.
The internal fastening plate is disposed at least partly within the flagpole body, and has an inner surface, an outer surface, an aperture disposed therein and at least two threaded fastening holes, each generally aligned to an internal fastener passage in the flagpole body. The external fastening plate is disposed at least partly outside of the flagpole body, and has an inner surface, an outer surface, an aperture disposed therein and at least two external fastener passages, each generally aligned to an internal fastener passage in the flagpole body.
Each of the threaded fasteners is disposed partly within an external fastener passage, partly within an internal fastener passage and partly within a threaded fastening hole. The winch mount is secured to one or more of the internal fastening plate, the external fastening plate and the flagpole body, and has a winch secured thereto.
In a third embodiment, the present invention is a flagpole assembly including a flagpole body, an internal fastening plate, an external fastening plate and door assembly and a winch mount.
The generally-cylindrical, hollow flagpole body has a first end, a second end, a principal axis, an inner surface, an outer surface, and an aperture disposed in the side thereof at least four internal fastener passages passing from the inner surface to the outer surface. The aperture passes from the inner surface to the outer surface along a radial axis substantially orthogonal to the principal axis.
The internal fastening plate is disposed within the flagpole body, having an inner surface, an outer surface, an aperture disposed therein and at least four threaded fastening holes, each threaded fastening hole generally aligned to an internal fastener passage in the flagpole body. The external fastening plate and door assembly is disposed at least partly outside of the flagpole body, and has an inner surface, an outer surface, a door aperture having a door disposed therein and at least four external fastener passages, each external fastener passage generally aligned to an internal fastener passage in the flagpole body.
Each of the threaded fasteners is disposed partly within an external fastener passage, partly within an internal fastener passage and partly within a threaded fastening hole. The winch mount is secured to the internal fastening plate and has a winch secured thereto.
