Extendable mast structures are commonly used to raise and lower sensor and/or antenna systems to perform required operations. The extended height of these mast systems can be as much as 10 meters or more, and require many electrical connections to the mast mounted equipment. A typical mast installation simply drapes a cable for such connections around the outside of the mast, coiling the cable like a spring. The typical alternate approach to this is to contain the cable system in a central open area within the mast, which is typically unused space or where drive components for the mast or electronic equipment may reside.
Features and advantages of the invention will be apparent from the detailed description which follows, taken in conjunction with the accompanying drawings, which together illustrate, by way of example, features of the invention; and, wherein:
Reference will now be made to the exemplary embodiments illustrated, and specific language will be used herein to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended.
DETAILED DESCRIPTIONAs used herein, the term “substantially” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, an object that is “substantially” enclosed would mean that the object is either completely enclosed or nearly completely enclosed. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained. The use of “substantially” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result.
As used herein, “adjacent” refers to the proximity of two structures or elements. Particularly, elements that are identified as being “adjacent” may be either abutting or connected. Such elements may also be near or close to each other without necessarily contacting each other. The exact degree of proximity may in some cases depend on the specific context.
An initial overview of technology embodiments is provided below and then specific technology embodiments are described in further detail later. This initial summary is intended to aid readers in understanding the technology more quickly but is not intended to identify key features or essential features of the technology nor is it intended to limit the scope of the claimed subject matter.
Although the current telescoping mast cable routing management designs are generally functional, the existing approaches do have drawbacks. For example, in a typical mast installation where the cable is around the outside of the mast, extension and retraction of the mast stretches the coiled cable “spring.” The coils of the cable are free to move and come into contact with one another as well as with the outside of the mast, which exposes the cable to both mechanical and environmental damage possibilities. In the typical alternate approach to this where the cable is contained in a central open area within the mast, space is limited for the amount of cable length required for full mast extension, which must compete for space with other mast systems and mechanisms, such as the mechanism for raising and lowering the mast sections. Thus, telescoping mast installations can benefit from an improved cable management approach, which can protect cables while preventing entanglement or kinking of the cables throughout extension and retraction of the telescoping mast and that avoids the interior spaces within the telescoping mast that are typically used or occupied by other components or payload, such as a drive motor and/or electronics.
Accordingly, a telescoping mast utility line management system is disclosed that protects utility lines from environmental hazards, prevents tangling and kinking during operation of the mast and maintains interior space within the mast for other required mast components. In one aspect, multiple utility lines for the mast can be incorporated. The telescoping mast utility line management system can include first and second panels for adjacent translatable portions of a telescoping mast, and a utility line arranged in a coil. A first coil portion can be coupled to the first panel and a second coil portion can be coupled to the second panel, such that relative telescoping translation of the first and second panels laterally displaces the first and second coil portions relative to one another.
A telescoping mast is also disclosed. The telescoping mast can comprise first and second translatable portions to extend and retract the mast. The first and second translatable portions can have first and second walls, respectively. The telescoping mast can also comprise a utility line arranged in a coil. A first coil portion can be coupled to the first wall and a second coil portion can be coupled to the second wall, such that relative telescoping translation of the first and second translatable portions laterally displaces the first and second coil portions relative to one another.
One embodiment of a telescoping mast 100 is illustrated in
The telescoping mast 100 can be of any suitable shape or configuration. For example, as shown in
In one aspect, described in more detail hereinafter, at least a portion of the utility line 120 can be disposed or located in spaces within and/or between adjacent translatable portions 110a-n, such as between walls or panels 111a-n. Such integration of the utility line 120 into or within the mast structure can provide a utility line management system that facilitates effective routing of the utility line 120 through the telescoping mast 100 to house and protect the utility line 120 while preventing entanglement or kinking of the utility line 120 throughout operation (i.e., extension and retraction) of the telescoping mast 100. In another aspect, the routing of the utility line 120 in such a manner can avoid interior spaces within the telescoping mast 100 that are typically used or occupied by other components or payload, such as a drive motor and/or electronics.
For example, a telescoping mast utility line management system 201 in accordance with an example of the present disclosure is illustrated in
As shown in
The coil portions 321a, 321b can be coupled to the telescoping portions such that relative telescoping translation of the telescoping portions, such as in directions 302, 303 parallel to an extension axis of the telescoping mast, laterally displaces the coil portions 321a, 321b relative to one another. Thus, in contrast to a coil with coil portions that are displaced parallel to an axis about which the coil is formed (i.e., stretched or compressed like a coil spring), the coil portions 321a, 321b experience lateral movement relative to one another in a direction perpendicular to a longitudinal axis 305 (axis extending into the page) (
Referring again to
The movable segment can be established by coupling the coil portion 221a to the panel 211b with clip 232b and to the panel 211a with clip 230a. This movable segment can change shape by partially straightening or uncoiling during relative movement of the panels 211a, 211b to extend the telescoping mast or by bending to form a loop shape when the panels 211a, 211b move relative to one another to retract the telescoping mast. Thus, the utility line 220 can be coupled or affixed to the panels 211a, 211b in certain locations to facilitate movement and bending of the utility line 220 in a controlled space and in a repetitive manner.
In one aspect, inward-turned edges of the panels (not shown) can serve or act as natural utility line guides and contain the utility line within the panel structure on one or more sides. In another aspect, the telescoping mast utility line management system 201 can include a utility line guide 240 coupled to provide a boundary for movement of the utility line 220 as the coil portions 221a, 221b laterally displace relative to one another. For example, in one example, the utility line guide 240 can comprise a base having a surface operable to interface with the utility line 220, and to facilitate the movement of the utility line 220 as described herein. The utility line guide 240 can be coupled to the panel 211b and positioned proximate the movable segment of the coil portion 221a to maintain a desired shape and/or position of the movable segment during relative movement of the panels 211a, 211b. In this case, the utility line guide 240 is oriented in a direction parallel to an extension/retraction direction 202, 203 of the telescoping mast. In one aspect, the location of the attachment points for the movable segment and/or the location and configuration of the utility line guide 240 can maintain the utility line 220 at a radius greater than or equal to a minimum bend radius of the utility line 220, thus preventing damage to the utility line 220 during operation of the telescoping mast.
The attachment points of the utility line 220 and/or the utility line guide 240 can also establish and/or maintain a desired shape or configuration of the utility line 220 in retracted and extended configurations of the telescoping mast. For example, in a retracted configuration of the telescoping mast, the coil portions 221a, 221b can comprise elongated loop shapes that coil/uncoil in a direction parallel to the extension/retraction direction 202, 203 of the mast as shown in
The two panels 211a, 211b and associated utility line 220 shown in
In one aspect, the telescoping mast utility line management system 201 can be incorporated in a telescoping mast by coupling the utility line 220 to an inner panel, such as panel 211a, which is smaller than panel 211b. The utility line 220 can be coupled to the panel 211a as illustrated in the figures or in any other suitable manner. The panel 211a can then be coupled to a corresponding inner telescoping portion of the mast. The utility line 220 can also be coupled to a panel that is an “outer” panel relative to the inner panel just installed, such as panel 211b. The utility line 220 can be coupled to the panel 211b as illustrated in the figures or in any other suitable manner. The panel 211b can then be coupled to a corresponding telescoping portion of the mast that is outward of the previous telescoping portion. This process can be repeated for any number of panels and telescoping portions of the mast. In one aspect, the installation procedure is performed on a retracted telescoping mast. This installation procedure can also be used to retrofit a telescoping mast utility line management system to an existing mast. In this case, certain panels of the mast can be removed and modified if needed and reinstalled with the utility line according to the installation procedure outlined above. Furthermore, the panels can be replaced by different panels during the installation procedure.
In one aspect, multiple utility lines can be incorporated into a single telescoping mast. For example, each “face” of the octagonal shape of the telescoping mast 100 of
