FIELD OF THE INVENTION
The present invention relates generally to the field of flagpole accessories, and more particularly to methods and systems for flagpole trucks for mounting on a top of a flagpole.
BACKGROUND OF THE INVENTION
Flagpoles are typically configured with a top-mounted flagpole truck, which provided means for mounting flag finial and for containing a pulley to which a flag halyard attaches.
However, such flagpole trucks are designed for either internal or external halyard mounting and have only limited options for rotational support. Therefore, changing mounting or rotational configuration is effectively impossible without replacement of the flagpole truck. Add, conventional external halyard mounts position the pully displaced to a side of the flag truck body, such that the pully is visible and exposed to the ambient environment.
As such, considering the foregoing, it may be appreciated that there continues to be a need for novel and improved devices and methods for field configurable flagpole trucks.
SUMMARY OF THE INVENTION
The foregoing needs are met, to a great extent, by the present invention, wherein in aspects of this invention, enhancements are provided to the existing model of flagpole trucks.
In an aspect, a field configurable flagpole truck system can include:
- a) A flagpole, such that a lower end of the flagpole can be mounted on a ground surface;
- b) A flagpole truck device, which is mounted on a top end of the flagpole, wherein the flagpole truck device, comprises a pulley assembly mounted inside an enclosure interior of the flagpole truck device;
- c) A flag, which is mounted on a top part of the flagpole;
- d) A halyard, which is connected to the flagpole truck device, around the pulley assembly, and connected to the flag, such that a movement of the halyard enables positioning of the flag; and
- e) A flagpole finial, which can be connected to a top of the flagpole truck device;
- such that the flagpole truck device can be configured in a first configuration, wherein the pulley assembly is positioned in a first position, such that first and second ends of the halyard each protrude downward from the flagpole truck device, such that the first and second ends of the halyard each protrude downward externally and visibly, to a side of the flagpole; and
- such that the flagpole truck device can be configured in a second configuration, wherein the pulley assembly is positioned in a second position,
- such that the first end of the halyard protrudes downward from the flagpole truck device externally and visibly, to a side of the flagpole, and the second end of the halyard protrudes downward from the flagpole truck device inside of an upper portion of the hollow flagpole.
In a related aspect, the flagpole truck device can include a blocking protrusion, which is connected to a bottom of the enclosure body; and a mounting stem structure of the flagpole truck device can include a first pin aperture and a second pin aperture, which is horizontally displaced to a side of the first pin aperture; and wherein the mounting stem assembly can further include:
- a) a first blocking pin, which is configured to be inserted into the first pin aperture, such that the first blocking pin protrudes horizontally from the mounting stem structure, such that the first blocking pin is configured to impact with the blocking protrusion to stop a rotation of the mounting stem assembly relative to the enclosure body; and
- b) a second blocking pin, which is configured to be inserted into the second pin aperture, such that the second blocking pin protrudes horizontally from the mounting stem structure to a side of the first blocking pin with a separation distance between the first blocking pin and the second blocking pin, such that the second blocking pin is configured to impact with the blocking protrusion to stop a rotation of the mounting stem assembly relative to the enclosure body;
- such that when neither of the first blocking pin and the second blocking pin are inserted in either of the first pin aperture and the second pin aperture, the mounting stem assembly is rotatable 360 degrees freely in either direction, whereby the enclosure body of the flagpole truck device is freely rotatable when the flagpole truck device is mounted on the flagpole;
- such that when solely one selected blocking pin is inserted in a selected pin aperture, the mounting stem assembly is rotatable in a restricted rotation range in either direction, wherein the restricted rotation range can be 359 degrees or less, whereby the enclosure body of the flagpole truck device is rotatable in the restricted rotation range when the flagpole truck device is mounted on the flagpole; and
- such that when the first blocking pin is inserted in the first pin aperture, and the second blocking pin is inserted in the second pin aperture, with the blocking protrusion positioned between the first blocking pin and the second blocking pin, the mounting stem assembly can be prevented from rotating, whereby the enclosure body of the flagpole truck device is rotatably fixed in position when the flagpole truck device is mounted on the flagpole.
There has thus been outlined, rather broadly, certain embodiments of the invention in order that the detailed description thereof herein may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional embodiments of the invention that will be described below and which will form the subject matter of the claims appended hereto.
