Embodiments of the present disclosure relate generally to portable devices for securing, installing, or mounting flagpoles or other elongate items to buildings or other structures for display. The portable devices of this disclosure are also suited for removal of items, holding items in place, or assisting in the completion of a task. One embodiment of this disclosure relates to devices and methods for the efficient installation of flagpoles within a flagpole holder or bracket mounted to a building or other structure.
Flags of various sizes are customarily flown from a pole. Frequently, the poles utilized to hold such flags are attached to buildings used in commerce, government, or downtown areas. Some flagpoles are permanently affixed to buildings. In this case, an individual seeking to display a flag would run the flag across a line attached to an eyelet at the end of the pole and unfurl the flag by movement of the line. However, most flagpoles are temporarily installed on buildings or utility poles via a mounted pole holder or bracket. Such holders or brackets are usually made of a durable material, such as aluminum, stainless steel, cast iron, or even certain plastics. The holders or brackets generally comprise a mounting plate for attachment to a surface and a holder (or bracket) portion. The holder portion may simply be a tubular member that is pivotally attached to the mounting plate, or it is often a fixed brace that allows a tubular member within. Since flags and other decorations must hang from a height sufficient to prevent damage or soiling by animals, pedestrians, and children, the mounting plate is usually attached to a structure between 5 feet and 30 feet from the ground. The height of the flagpole holders or brackets from the ground can cause problems when deploying flags or other items.
A need exists for an apparatus, system, and method for deploying flagpoles and other elongate items quickly, safely, and efficiently to flagpole holders and other brackets mounted to buildings, utility poles, or other structures. Since mounted flagpole holders and brackets are predominantly utilized in public and private spaces throughout the United States and internationally, the responsibility of hanging flags (or other items) falls to either the private property owner or a public works department. The most common solution to this problem is for a property owner or public works technician (an “installer”) to align a ladder with the mounted holder/bracket, carry the flagpole (with the flag attached) up the ladder, and manually place the flagpole within the flagpole holder or bracket. The drawbacks of such a method are many-fold. For example, this method is labor intensive, as the installer must carry the large ladder wherever flags or other items are to be displayed. In addition, the installer runs the risk of falling from the ladder, even if aided by a helper or second installer. Moreover, a large vehicle must be utilized to move the ladder, or the installer must utilize a bucket truck for large jobs, which disrupts traffic, heightens environmental impact, and raises capital equipment costs to an unacceptable level.
A solution has long been sought for the safe and efficient securing, mounting, installation, and display of flags or other items. Some devices and methods utilizing various techniques have been previously disclosed, including those described in U.S. Pat. Nos. 6,883,459; 8,291,852; and 9,852,668. These patents disclose a variety of combinations and configurations for display or mounting devices and techniques, but none provides a satisfactory solution. These devices fail to suitably account for the presence of mounted flagpole brackets, portability of the device, ease of operator use, and environmental impact. In one embodiment, the present disclosure provides a portable device adapted for effective securing and deployment of a wide variety of elongate items, particularly flagpoles into mounted flagpole holders, in a safe and environmentally acceptable manner. The present disclosure further provides securing devices for removal of items, holding items in place, or assisting in the completion of a task.

Referring now to the drawings wherein like numerals refer to like parts,
Extension portion 180 may be a fixed-length single pole, a fixed-length pole comprising multiple pieces, an extension pole that is modifiable in length, or the like. One example of an extension pole that is modifiable in length is a telescoping pole. Extension portion 180 may also take on a variety of geometries. In some embodiments, extension portion 180 may be straight along its length running from the bottom of securing device 100 to grabber portion 110. In other embodiments, such as the embodiment illustrated in
Extension portion 180 may also include eyelets 184, 186 for allowing a cable 188 therethrough. Cable 188 is attached to sliding member 130 at grabber portion 110 and is available for an operator to pull in order to actuate sliding member 130. Cable 188 may be placed with securing device 100 and travel through an interior of extension portion 180. Alternatively, cable 188 may hang freely from sliding member 130. It is preferred for cable to run either within the length of extension portion 180 or on the exterior, alongside extension portion 180. In embodiments where cable 188 runs on the exterior of extension portion 180, a handle may be attached to the end of cable 188. The handle may be fastened or otherwise removably attached to extension portion 180 by a projecting ring or collar, a clip, a flange, magnets, or the like. This allows an operator to keep cable 188 clear of the working area during use of securing device 100.
Sliding member 130 generally comprises a tube that is sized with an inner diameter large enough to slidably engage the exterior of core 122. In certain embodiments, sliding member 130 may also include slot 132 and tabs 134, 136. Slot 132 accommodates the presence of reinforcing member 140, while also allowing sliding member 130 to slide or move along the length of core 122. Tabs 134, 136 provide closure to u-shaped section 124 of loading zone 120 when sliding member 130 is in its unactuated state. When sliding member 130 is in an unactuated state, grabber portion 110 is in a closed configuration (as shown in
Reinforcing member 140 is shown in
In the embodiment shown in
Guide 150 is shown in
In operation, a user prepares a flagpole or other elongate item to be installed via use of securing device 100. The user holds securing device 100 at extension portion 180 and pulls cable 188 to actuate sliding member 130 and provide access to loading zone 120. The user then orients securing device 100 so that the flagpole or other elongate item is within loading zone 120, optionally by use of flange 126. Operator then releases cable 188, allowing sliding member 130 to return to its unactuated state, biased toward the top of grabber portion 110. The flagpole or other elongate item is now stable within loading zone 120 of securing device 100. The user then, optionally using guide 150, may align securing device 100 with a target installation site. Once the flagpole or other elongate item is aligned with the target installation site, the user may pull cable 188, which retracts sliding member 130 and opens loading zone 120 via u-shaped section 124. The flagpole or other elongate item is freed from loading zone 120, the user releases cable 188, and securing device returns to its original state and is ready for re-use.
In another method of operation, a user may secure a tool or other implement to securing device 100 for completion of a task. For instance, an operator may use securing device 100 to clean gutters by the placement and securing of a hose in loading zone 120. The user holds securing device 100 at extension portion 180 and pulls cable 188 to actuate sliding member 130 and provide access to loading zone 120. The user then orients securing device 100 so that a hose is within loading zone 120. Operator then releases cable 188, allowing sliding member 130 to return to its unactuated state, biased toward the top of grabber portion 110. The hose is now stable within loading zone 120 of securing device 100. The user may then align securing device 100 with a target, such as a gutter in need of cleaning. Once the hose is aligned with the target site, the user may turn on a water supply to the hose and blast dirt and debris out of the gutter via the water pressure of the hose. When the gutter cleaning is complete, the user may pull cable 188, which retracts sliding member 130 and opens loading zone 120 via u-shaped section 124. The hose is then freed from loading zone 120, the user releases cable 188, and securing device returns to its original state and is ready for re-use.
In yet another method of operation, securing device 100 may be used for safely gripping and removing items or debris in high places. For instance, an operator may use securing device 100 during tree pruning to remove pruned tree branches by the placement of a branch to be pruned within loading zone 120. The user holds securing device 100 at extension portion 180 and pulls cable 188 to actuate sliding member 130 and provide access to loading zone 120. The user then orients securing device 100 so that a branch to be pruned is within loading zone 120. Operator then releases cable 188, allowing sliding member 130 to return to its unactuated state, biased toward the top of grabber portion 110. The branch to be pruned is now stable within loading zone 120 of securing device 100. The user may then prunes the branch, freeing it from the tree. Once the user moves securing device 100 to a safe location, the user may pull cable 188, which retracts sliding member 130 and opens loading zone 120 via u-shaped section 124. The pruned branch is then freed from loading zone 120, the user releases cable 188, and securing device returns to its original state and is ready for re-use.
A method for making a securing device is provided below. The method includes providing a core for grabber portion by forming a u-shaped section in a tubular member, such as 1-inch schedule 40 aluminum tube, having an outer diameter of about 1.32 inches. A flange may be formed with or attached to the core adjacent the u-shaped section. A reinforcing member, such as a piece of ¼-inch aluminum flat stock or the like, may be attached to the core, preferably by welding. Alternatively, the core and reinforcing member (and optional flange) may be formed as one piece, as described above.
A sliding member is made by forming or providing at least a portion of a cylinder. The cylinder may be a length of 1¼-inch schedule 40 aluminum tubing having and inner diameter of about 1.38 inches. Sliding member may be between 3 and 36 inches in length, but a sliding member of around 6-18 inches is preferred. The inner diameter of the sliding member should be slightly larger than the outer diameter of the core. Once the dimensions of the sliding member are set, a slot and tab may be formed on the sliding member. The sliding member is placed over the core, such that the reinforcing member is within the sliding member's slot, and at least one of the sliding member's tabs covers the u-shaped section of the core. A cable is attached to the sliding member and either runs through the inside of the core, to the exterior of the sliding member, or is allowed to hang freely from the sliding member. One or more springs having a first end and second end are attached to the sliding member at the first end and anchored to the reinforcing member or core at the second end such that the one or more springs are under tension while sliding member is at rest.
An extension portion may be attached to or coextensive with the core. Optionally, a bend between zero and 90 degrees may be formed in extension portion as described above. An optional guide may be made by providing or forming an attachment flange e.g., from metal or polymer flat stock. An extension arm may be formed with, affixed, or otherwise connected to the attachment flange, and a receiver may be formed with, affixed, or otherwise connected to the extension arm. The receiver may be made by bending flat stock to a desired configuration, preferably one that compliments the installation site of standard flagpole holders or mounted brackets. Alternatively, the receiver may be formed by cutting out a portion of a tubular member, such as a three-inch section of 1¼-inch schedule 40 aluminum tube, and then halving the tube to provide the shape of receiver 156 shown in
Most of the components of securing device 100 may be formed by any known manufacturing process for metal parts, such as machining, molding, welding, pressing, injection molding, CNC machining, 3-D printing, or the like.
In all embodiments, securing device 100 may have one or more handles associated with extension portion 180 that allows a user to comfortably hold and use the device. For instance, a single handle grip may be utilized on extension portion 180 where an operator holds the device to enhance grip or comfort. A second handle may be a side handle attached to and extending at a right angle from extension portion 180 to enhance device maneuverability. Such a side handle may be those found on the market manufactured by DeWalt or Milwaukee Tool, however a side handle may also be fabricated to fold and lay parallel to extension portion 180 while not in use. Alternatively or additionally, extension portion 180 of securing device 100 may include a trigger or automated actuation mechanism for actuating sliding member 130. Extension portion 180 may alternatively or additionally include an interface, driveshaft, and/or a transmission (e.g., chain, gears, or the like) allowing for the attachment of a tool (e.g., a rotary power tool) and/or the actuation of sliding member 130.
Furthermore, extension portion 180 may be modular. As a non-limiting example, extension portion 180 may have a total length of 10 feet. To increase portability of the device, extension portion 180 may be divided into 3 sections equivalent in length. Each section may be attached via threaded couplings at their ends, via a quick-release mechanism such as retractable pins, via welded couplings, and/or via fasteners (such as bolts or screws). In addition, a coupling incorporating bends of various angles may be utilized in such a modular system. For instance, if a user requires around a 7-foot extension with a 22-degree bend, the invention provides for two sections of extension tube three-feet in length and one coupling with a 22-degree bend (of about 12 inches in length) that are assembled in the field via threads, quick-release, fasteners, or the like and attached to grabber portion 110 for use.
In another embodiment, securing device 100 may have an overall length of 10 feet, where grabber portion 110 is six feet long and incorporates a coupling for an extension pole, and the extension pole provides about another four feet of overall length. In this embodiment, core 122 would extend about two to four feet past sliding member 130 (and may include an angle or bend). The core may have the coupling for an extension pole attached to its bottom end via welding or other forms of attachment. The coupling for an extension pole may comprise a 6-inch to 24-inch length of 1¼-inch schedule 40 aluminum tube welded to the core's bottom or terminal end. The coupling for the extension pole may further include holes, pins, or other anchors on its end opposite the core, which may be used for attachment of the extension pole (e.g., a length of 1-inch schedule 40 aluminum tube). It is preferred for the length of the extension pole to be about four feet, but any length suitable for mounting flagpoles or other elongate items may be employed.
It should be noted that in all embodiments including a loading zone or core, the portion referred to herein as a “u-shaped section” or u-shaped section 124 is not limited to a u-shape. For instance, such a section could easily be described as a c-shaped section, a rectangular-shaped section, an open portion, an opening, or a dock. However, it should also be noted that in embodiments of a device used specifically for flagpoles, a u-shaped section or c-shaped section is preferred, as most flagpoles are cylindrical in shape, and a u-shape or c-shape compliments the profile of the item to be installed. Utilizing such a complimentary profile for loading zone provides certain advantages, such as increased ease of placing the item within the loading zone and increased stability when the installation device is loaded.
The disclosed embodiments have many attendant advantages. As a first example, the installation device of the present invention provides an efficient solution for mounting or placing flagpoles, decorations, or other items without the use of a ladder or bucket truck in a city or municipality with mounted flagpole holders or brackets. As a second example, the guides utilized in various embodiments of the invention provide enhanced ease and comfort of use to operators. As a third example, the embodiments of the invention provide decreased environmental impact by providing a solution that does not require the use of high-powered trucks or devices burning fossil fuels. As a fourth example, various embodiments of the securing device allow for gripping and utilization of tools in high places, such as a hose for gutter cleaning. As a fifth example, various embodiments of the securing device allow for safe gripping and removal of items or debris in high places, such as pruned tree branches.
It should be understood that various changes and modifications to the presently disclosed embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present inventions and without diminishing their attendant advantages. It is, therefore, intended that such changes and modifications be covered by any prospective claims concerning this disclosure.
