Definitions
- This invention relates generally to transmission lines and, in particular, to stackable transmission line hangers for supporting one or more transmission lines for an antenna system.
- Transmission line hangers are used to support transmission lines. Generally, a transmission line is inserted into a transmission line hanger which is then attached to a supporting structure. The most extensive use of hangers is in connection with coaxial cables, such as those disclosed in U.S. Pat. No. 5,334,051 to Devine et al. and U.S. Pat. No. 5,167,533 to Rauwolf. Coaxial cables are extensively used for carrying a variety of electromagnetic signals. In most uses, the cables need to be attached to a supporting structure along most of their lengths.
- Transmission line hangers are also used for supporting waveguides which carry electromagnetic signals from transmitting or receiving equipment in an equipment shelter to an antenna mounted on a tall tower.
- a large number of hangers are required to support a waveguide beneath a horizontal waveguide bridge extending between the shelter and the base of the tower and to support the waveguide on the tower as the waveguide extends upwardly to the antenna.
- An even larger number of hangers are required where separate waveguides extend to several antennas on a signal tower.
- Commercially available waveguides have a variety of cross-sectional shapes. For example, a variety of waveguide shapes are disclosed in U.S. Pat. No. 3,822,411 to Merle and U.S. Pat. No. 4,047,133 to Merle.
- transmission line hangers are attached to a supporting structure, such as a transmission line bridge or an antenna tower, by inserting a bolt through a U-shaped hanger and through a hole in the supporting structure. The bolt is held in place by a nut and lock washer. After the hangers have been attached to the supporting structure, the transmission line is strung along the bridge, up the tower, and clamped between the legs of each U-shaped hanger by tightening a clamping screw which extends between the legs. A considerable amount of installation time is required, first to attach the large number of hangers to the bridge and the tower and then to clamp the transmission line within the hangers. In addition, a large amount of auxiliary hardware (e.g., screws, bolts, nuts, and washers) is required, along with the hangers themselves.
- auxiliary hardware e.g., screws, bolts, nuts, and washers
- a spring hanger system for supporting a VHF circular waveguide is disclosed in U.S. Pat. No. 4,654,612 to Smith.
- a variety of prior hangers for microwave transmission lines are disclosed in Andrew Corporation Catalog #36.
- An improved waveguide hanger is disclosed in U.S. Pat. No. 4,763,132 to Juds et al.
- the waveguide hanger disclosed therein is in the form of a resiliently yieldable and generally U-shaped clip that is adapted to be slipped over an elliptical waveguide and snapped into a supporting structure.
- the clip includes a hinge portion that extends between the legs of the clip.
- the cable hanger disclosed therein includes a hinge section, a cable retention section, and a structure attachment section having two locking members that each include a pair of concave locking barbs. Cable hangers that include a hinge section can only accommodate a limited range of cable diameters. The maximum cable diameter accepted by such cable hangers is limited by the maximum circumference of the cable retention section.
- Prior transmission line hangers such as those disclosed in Nelson and Juds et al., also place the cable retention section close to the attachment section.
- the attachment section is traditionally short in length. This makes the attachment section rigid and non-compliant which makes installation of such hangers difficult, especially where a large diameter cable is being installed on a tower or where the weather conditions limit manual dexterity, e.g., cold weather.
- tools may be required to squeeze the hanger into the tower aperture. The use of tools is undesirable, especially where a transmission line is being installed on a tall tower.
- hangers without mechanisms for penetrating or biting into the cable jacket cannot prevent longitudinal movement of the cable because the frictional coefficient between the metal hanger and the plastic cable jacket is very low.
- the polyethylene typically used for cable jackets is a soft material that has an inherent lubricant quality.
- the cable jacket can “cold flow” which reduces the holding force of the cable hanger over time, resulting in cable slippage.
- the bolt of the first hanger has to be removed, the two hanger halves of another hanger must be placed around the new transmission line(s) and the four hanger halves must be assembled together by inserting a bolt through the hangers and through a hole in the supporting structure and fastening a lock washer and a nut to the bolt. Therefore, there is a need for a novel stackable transmission line hanger that is easy to install, easy to add additional transmission lines thereto, and inexpensive to manufacture.
- the installation of one or more transmission lines along a supporting structure is often a difficult and time-consuming operation because of the large amount of auxiliary hardware required to install some prior hangers and/or the necessity to remove an assembled hanger to add an additional transmission line. Therefore, there is a continuing need for easy to install stackable hangers and for improved methods of installing them.
- the present invention addresses these needs by providing a one piece, stackable transmission line hanger capable of securing one or more transmission lines.
- the stackable hanger is expandable to accommodate additional transmission lines without unassembling the prior hanger(s), is expandable to accommodate a large number of transmission line diameters, is inexpensive to produce, and is quickly and easily installed.
- the stackable hanger reduces the number of components required to secure one or more transmission lines, reduces installation time, reduces longitudinal movement of the transmission line within each hanger, and allows for simple installation of additional transmission lines.

- a one piece or unitary hanger is less expensive to produce and more reliable than hangers composed of several pieces.
- a stackable transmission line hanger for securing one or more transmission lines to a supporting structure.
- Each such hanger includes a transmission line retention section for accommodating a transmission line and a mounting section extending from the transmission line retention section.
- the mounting section supports a mounting hole disposed therein.
- the hanger 10 is generally U-shaped and includes arms 11 .
- the transmission line retention section includes a first leg 14 and a second leg 16 extending therefrom.
- the first and second legs 14 , 16 connected to the retention section at a curved joint and a compliant area between the mounting section and the retention section allow the hanger to accommodate various sizes of transmission lines.
- the first and second legs 14 , 16 adjoin a locking barb configured to lock against an attachment surface.
- One or more of the hangers 10 can be used to support one or more transmission lines, including circular coaxial cables and waveguides, in generally parallel rows.
- the hanger 10 can accommodate a large range of different transmission line diameters.
- One row of the hangers 10 generally secures one transmission line to a supporting structure, such as a horizontal transmission line bridge or a vertical antenna tower.
- One or more additional rows of the hangers 10 can secure one or more additional transmission lines by attaching to the respective transmission line hangers in the first row.
- the hangers 10 are easy to install because no ancillary hardware is required, such as nuts, bolts, or screws.
- the hanger 10 is illustrated.
- the hanger 10 is a unitary structure essentially composed of metal.
- the hanger 10 is composed of stainless steel having a thickness of 0 . 76 mm and is generally U-shaped.
- the illustrated hanger 10 includes a mounting section 100 , a transmission line retention section 102 , an extended section 104 , and an attachment section 106 .
- the mounting section 100 extends from the retention section 102 .
- the mounting section 100 includes a snap-in stacking provision, such as a mounting hole 108 disposed therein, as shown in FIGS. 1 and 4 .
- the retention section 102 includes two opposing curved members 12 and 13 that accommodate a transmission line 15 which is shown in dotted lines in FIG. 1 .
- the curved members 12 , 13 support a first leg 14 and a second leg 16 , respectively, that comprise the extended section 104 .
- the first and second legs 14 , 16 extend from the respective curved members 12 , 13 .
- a compliant area 110 is disposed between the mounting section 100 and the retention section 102 and allows the first and second legs 14 , 16 to be pressed towards each other and to expand away from each other by spring force.
- the extended section 104 includes a pair of spring fingers 29 projecting inwardly from the extended section 104 and into the retention section 102 , as illustrated in FIG. 2 .
- the first leg 14 includes one pair of spring fingers 29 flexibly connected thereto and projecting inwardly therefrom.
- the second leg 16 includes a second pair of spring fingers 29 flexibly connected thereto and projecting inwardly therefrom.
- the spring fingers 29 are flexibly connected to the respective legs 14 , 16 such that when a transmission line is inserted into the hanger 10 , the spring fingers 29 flex outward with respect to the respective legs 14 , 16 , and force the transmission line against a pair of opposing transmission line stops 30 .
- the spring fingers 29 provide spring resistance against the transmission line after it is inserted in the hanger 10 .
- the spring fingers 29 and the stops 30 help minimize the longitudinal movement of the transmission line in the hanger 10 even on smooth (non-corrugated) transmission lines. Longitudinal movement is defined as movement in a direction parallel to the length of the transmission line.
- the spring fingers 29 are not connected at a first and second leg 17 , 19 . Instead, the spring fingers 29 are connected to and extend from a portion of the curved members 12 , 13 above the first and second legs 17 , 19 . This stiffens the region between the extended section 104 and the attachment section 106 . Thus, if the retention section 102 pivots or rocks to one side, the extended section 104 and the attachment section 106 remain centered, which aids in keeping the hanger 10 in place.
- the stackable, snap-in hanger 10 requires no additional hardware to install it to an attachment surface.
- prior hanger assemblies required hardware such as lock washers and nuts to secure a transmission line to a supporting structure. These parts tended to loosen over time with vibration caused by, e.g., wind gusts.
- the hanger 10 includes the spring fingers 29 which help to minimize transmission line vibration.
- the hanger 10 insures that an improper amount of torque is not applied to a hanger assembly because there is no additional hardware required to fasten the hanger 10 to an attachment surface.
- the compliant area 110 in conjunction with the spring fingers 29 , allows the hanger 10 to have the compliance necessary to accommodate a large range of different transmission line diameters.
- the extended section 104 also contributes compliance at its curved joint with the retention section 102 to further allow the hanger 10 to accommodate a large range of transmission line diameters and still allow the attachment section 106 to be inserted into an aperture in an attachment surface, such as a supporting structure 5 or the mounting hole 108 of another hanger 10 , as shown in FIG. 5 .
- Prior hangers without an extended section between the transmission line retention section and the attachment section had essentially no compliance.
- the extended section 104 in conjunction with the pair of spring fingers 29 , allows the hanger 10 to accommodate a large range of different transmission line diameters by having the compliance to expand for larger transmission lines.
- the extended section 104 and the spring fingers 29 also have the compliance to allow the hanger 10 to accommodate a large range of transmission line diameters while still allowing the attachment section 106 to be inserted into an attachment surface.
- the shape of the retention section 102 and the attachment section 106 of the hanger 10 do not change significantly in response to supporting different diameter transmission lines.
- the flexibility of the spring fingers 29 allows the spring fingers 29 to flex inward with respect to the extended section 104 after a transmission line has been inserted into the retention section 102 .
- the flexibility of the extended section 104 allows the attachment section 106 to be inserted into an aperture in an attachment surface without significantly changing the shape of the transmission line retention section 102 despite different diameter transmission lines being supported by the hanger 10 .
- the attachment section 106 includes a first section 18 that extends from each of the first and second legs 14 , 16 , respectively.
- a second section 20 extends from the first section 18 and forms a locking barb 22 that is configured to lock against an attachment surface once the locking barb 22 is inserted through an aperture in the attachment surface.
- the locking barb 22 is integral with the second section 20 and extends from and is generally orthogonal thereto.
- Each locking barb 22 includes a barb contact point or line 23 for contacting the attachment surface.
- the locking barb 22 is integral with the second section 20 , but also includes a curved folded-over rib 22 a ( FIG. 15 ).
- the folded-over rib 22 a links the second section 20 and the locking barb 22 .
- the folded-over rib 22 a is curved to provide greater strength to the locking barb 22 , which increases the ability of the locking barb 22 to grasp the edge of the aperture.
- the locking barb 22 is dimensioned to match the shape of the aperture of the attachment surface.
- the locking barb 22 is curved to match the curvature of the aperture ( FIG. 15 ). If the aperture is square, then the locking barb 22 is a straight edge to match the side of the aperture. Configuring the locking barb 22 to match the shape of the aperture creates a stiffer locking barb 22 that is able to better grasp the aperture.
- FIG. 6 shows how the attachment section 106 is secured to the supporting structure 5 which can include, for example, a horizontal transmission line bridge or a vertical antenna tower.
- the supporting structure 5 includes a circular aperture 50 defined by a wall 52 .
- the first section 18 contacts the wall 52 at one or both of a pair of contact points 54 and 56 .
- the locking barb 22 is configured to lock against the supporting structure 5 once the locking barb 22 is inserted through the aperture 50 .
- the supporting structure 5 includes an outer surface 58 and an inner surface 60 .
- the surfaces of the supporting structure may be rough due to, for example, irregularities, bubbles, and/or barbs caused by the galvanizing process and/or the punching process that produces the aperture 50 .
- the hanger 10 is designed such that each locking barb 22 contacts the inner surface 60 of the supporting structure 5 at the barb contact point or line 23 . Because the hanger 10 includes two locking barbs 22 , one on each leg 14 , 16 , the hanger 10 can be more securely attached to the supporting structure 5 , despite any irregularities on the inner surface 60 .
- the wall 52 of the aperture 50 may also be rough because of irregularities, bubbles, and/or barbs caused by the galvanizing process and/or the punching process that produces the aperture 50 . Therefore, in one embodiment, contact with these irregularities is minimized by having the first section 18 of the hanger 10 only contact the wall 52 at one or both of the pair of contact points 54 , 56 , instead of, e.g., a curved surface contacting a large portion of the wall 52 .
- FIG. 7 shows how the attachment section 106 is secured to the mounting section 100 of another hanger 10 .
- the mounting section 100 includes a square mounting hole 108 disposed therein.
- the locking barb 22 is configured to lock against the mounting section 100 once the locking barb 22 is inserted through the mounting hole 108 .
- the square mounting hole 108 is defined by a wall 112 having a pair of opposing lips 114 , as shown in FIGS. 2, 4 and 7 .
- the square mounting hole 108 provides an anti-rotation feature that keeps the hangers 10 aligned.
- the locking barb 22 includes a notch 116 that is configured to lock against the lip 114 of another hanger 10 once the locking barb 22 is inserted through the mounting hole 108 and the first and second legs 14 , 16 are released.
- the notch 116 insures that the second row hanger 10 is aligned with the first row hanger 10 .
- the aligned hangers 10 insure that the transmission lines secured therein are generally parallel to each other.
- the notch 116 in each locking barb 22 insures a secure connection between each additional hanger 10 .
- the notches 116 lock the distal end of both legs 14 , 16 against the opposing lips 114 of the mounting section 100 of another hanger 10 , as shown in FIG. 7 .
- the locking barb 22 has two notches 116 ( FIGS. 14 and 16 ) to decrease the likelihood of having the barb disengage the lip 114 .
- the mounting hole 108 is circular in shape and has a lip (or stiffening flange) 115 that encompasses the entire mounting hole 108 .
- a lip or stiffening flange
- hangers 10 can act as a “spring” during a wind gust rather than as a rigid member.
- the hanger 10 also includes first and second legs 17 , 19 ( FIG. 12 ) that extend down from a portion of the curved members 12 , 13 to help decrease the likelihood of the hangers 10 becoming disengaged during a wind gust.
- first and second legs 17 , 19 rest against the top of the attachment surface and provide support.
- the first and second legs 17 , 19 are a gussetted flap of metal.
- the first and second legs 17 , 19 have out-turned flanges 17 a that are generally orthogonal to the first and second legs 17 , 19 .
- the out-turned flanges 17 a act like a brace on the attachment surface if the hanger 10 were to sway due to wind.
- the out-turned flanges 17 a are structured to dig into the attachment surface. More specifically, the out-turned flanges 17 a each include a sharp point 17 b that digs into the attachment surface, effectively gripping the surface during high wind gusts.
- the attachment section 106 stays centered over the aperture of the attachment surface, keeping the locking barbs 22 in place.
- out-turned flanges 17 a along with in-turned flanges 19 a on the first and second legs 17 , 19 create a wider “footprint” on the attachment surface.
- the wider “footprint” decreases the likelihood of the attachment section 106 disengaging from the attachment surface during high winds.
- the compliant area 110 is provided by a fulcrum or bend.
- the compliant area 110 enables the first and second legs 14 , 16 to be pressed together, thus, allowing the locking barbs 22 to fit through an aperture in an attachment surface.
- the compliant area 110 also allows the first and second legs 14 , 16 to expand by spring force once the locking barb 22 is inserted through the aperture. This expansion brings the first section 18 into contact with, e.g., the wall 52 of the aperture 50 at one or both of the pair of contact points 54 , 56 , as shown in FIG. 6 . Alternatively, this expansion also brings the notch 116 into contact with the lip 114 of the mounting hole 108 of another hanger 10 , as shown in FIG. 7 .
- the design of the hanger 10 and, in particular, the extended section 104 allows for easy installation of the hanger 10 .
- the extended section 104 allows larger diameter transmission lines to be inserted into the hanger 10 .
- the user then wraps his or her fingers around the hanger 10 , and the transmission line therein, and presses the legs 14 , 16 together.
- the extended section 104 places the retention section 102 further away from the attachment surface, such as the supporting structure 5 or the mounting section 100 .
- the attachment section 106 is closer to the user's fingers and thumb, thus, allowing a greater range of motion and greater force to be applied to the hanger 10 when inserting the attachment section 106 into an attachment surface.
- the extended section 104 also gives the user more room to work, and avoids the user's hands from hitting the attachment surface during installation.
- the mounting section 100 further extends the distance the user's fingers and thumb are from the attachment surface.
- the design of the hanger 10 and, in particular, the extended section 104 also provides a more dynamic snap-in action than prior hangers when the hanger 10 is installed into an attachment surface.
- the two locking barbs 22 also provide less insertion resistance than prior hanger designs having four locking barbs. Having only two locking barbs 22 reduces the number of contact points that must contact, for example, the outer surface 58 of the supporting structure 5 during insertion of the hanger 10 into the supporting structure 5 .
- the two barb design of the attachment section 106 reduces insertion resistance by reducing the cam pressure required and the amount of deflection required to insert the hanger 10 into an attachment surface. This reduces the amount of force required to insert the hanger 10 into, for example, a supporting structure or a mounting section of another hanger 10 .
- the hanger 10 requires less manual dexterity to install and uninstall than prior hangers.
- the ergonomic design of the hanger 10 allows for easier installation. These are important features, especially where the typical transmission line is in excess of 1 , 000 feet and a hanger is mounted every three feet. Consequently, hundreds of hangers must be installed to support such a transmission line. The hours required to install that many hangers is great. Accordingly, transmission line installation is costly. In addition, it can be difficult to find someone willing to install transmission line hangers high above the ground, especially if extra hardware is required to install the hangers. Therefore, a hanger that requires less installation time and is easier to install reduces the number of hours required for installation, thus, reducing installation costs.
- the extended section 104 includes spring finger 29 projecting inwardly from the extended section 104 and into the retention section 102 .
- the first leg 14 may include the spring finger 29 flexibly connected thereto and projecting inwardly therefrom.
- the spring finger 29 is flexibly connected to the first leg 14 such that when a transmission line is inserted into the hanger 10 , the spring finger 29 flexes outwardly with respect to the first leg 14 and forces the transmission line against the transmission line stop 30 on the opposing leg 16 .
- the spring finger 29 can provide spring resistance against the transmission line after it is inserted in the hanger 10 .
- the spring finger 29 also bites into the jacket of the transmission line to further secure the transmission line within the hanger 10 .
- the spring finger 29 and the stops 30 help minimize the longitudinal movement of the transmission line in the hanger 10 even on smooth (non-corrugated) transmission lines.
- the spring finger 29 also helps minimize transmission line vibration.
- the second leg 16 may include the spring finger 29 flexibly connected thereto and projecting inwardly therefrom that forces the transmission line against the right transmission line stop 30 .
- the extended section 104 in conjunction with the spring finger 29 , allows the hanger 10 to accommodate a large range of different transmission line diameters by having the compliance to expand for larger transmission lines.
- the extended section 104 and the spring finger 29 also have the compliance to allow the hanger 10 to accommodate a large range of transmission line diameters while still allowing the attachment section 106 to be inserted into an attachment surface.
- the transmission line stops 30 and spring fingers 29 are also configured to adapt to a large range of transmission line diameters.

Description
- This application is a continuation-in-part of co-pending U.S. patent application Ser. No. 09/430,496 filed Oct. 29, 1999, now issued as U.S. Pat. No. 6,354,543 on Mar. 12, 2002, which is a continuation-in-part of U.S. patent application Ser. No. 09/229,843 filed Jan. 12, 1999, now issued as U.S. Pat. No. 6,161,804 on Dec. 19, 2000.
- This invention relates generally to transmission lines and, in particular, to stackable transmission line hangers for supporting one or more transmission lines for an antenna system.
- Transmission line hangers are used to support transmission lines. Generally, a transmission line is inserted into a transmission line hanger which is then attached to a supporting structure. The most extensive use of hangers is in connection with coaxial cables, such as those disclosed in U.S. Pat. No. 5,334,051 to Devine et al. and U.S. Pat. No. 5,167,533 to Rauwolf. Coaxial cables are extensively used for carrying a variety of electromagnetic signals. In most uses, the cables need to be attached to a supporting structure along most of their lengths.
- Transmission line hangers are also used for supporting waveguides which carry electromagnetic signals from transmitting or receiving equipment in an equipment shelter to an antenna mounted on a tall tower. A large number of hangers are required to support a waveguide beneath a horizontal waveguide bridge extending between the shelter and the base of the tower and to support the waveguide on the tower as the waveguide extends upwardly to the antenna. An even larger number of hangers are required where separate waveguides extend to several antennas on a signal tower. Commercially available waveguides have a variety of cross-sectional shapes. For example, a variety of waveguide shapes are disclosed in U.S. Pat. No. 3,822,411 to Merle and U.S. Pat. No. 4,047,133 to Merle.
- Typically, transmission line hangers are attached to a supporting structure, such as a transmission line bridge or an antenna tower, by inserting a bolt through a U-shaped hanger and through a hole in the supporting structure. The bolt is held in place by a nut and lock washer. After the hangers have been attached to the supporting structure, the transmission line is strung along the bridge, up the tower, and clamped between the legs of each U-shaped hanger by tightening a clamping screw which extends between the legs. A considerable amount of installation time is required, first to attach the large number of hangers to the bridge and the tower and then to clamp the transmission line within the hangers. In addition, a large amount of auxiliary hardware (e.g., screws, bolts, nuts, and washers) is required, along with the hangers themselves.
- A spring hanger system for supporting a VHF circular waveguide is disclosed in U.S. Pat. No. 4,654,612 to Smith. A variety of prior hangers for microwave transmission lines are disclosed in Andrew Corporation Catalog #36. An improved waveguide hanger is disclosed in U.S. Pat. No. 4,763,132 to Juds et al. The waveguide hanger disclosed therein is in the form of a resiliently yieldable and generally U-shaped clip that is adapted to be slipped over an elliptical waveguide and snapped into a supporting structure. The clip includes a hinge portion that extends between the legs of the clip.
- Another cable hanger is disclosed in U.S. Pat. No. 5,393,021 to Nelson. The cable hanger disclosed therein includes a hinge section, a cable retention section, and a structure attachment section having two locking members that each include a pair of concave locking barbs. Cable hangers that include a hinge section can only accommodate a limited range of cable diameters. The maximum cable diameter accepted by such cable hangers is limited by the maximum circumference of the cable retention section.
- Prior transmission line hangers, such as those disclosed in Nelson and Juds et al., also place the cable retention section close to the attachment section. Thus, the attachment section is traditionally short in length. This makes the attachment section rigid and non-compliant which makes installation of such hangers difficult, especially where a large diameter cable is being installed on a tower or where the weather conditions limit manual dexterity, e.g., cold weather. In such situations, tools may be required to squeeze the hanger into the tower aperture. The use of tools is undesirable, especially where a transmission line is being installed on a tall tower.
- Furthermore, some prior hanger designs do not adequately prevent longitudinal movement of the cable with respect to the hangers. Hangers without mechanisms for penetrating or biting into the cable jacket cannot prevent longitudinal movement of the cable because the frictional coefficient between the metal hanger and the plastic cable jacket is very low. The polyethylene typically used for cable jackets is a soft material that has an inherent lubricant quality. In addition, the cable jacket can “cold flow” which reduces the holding force of the cable hanger over time, resulting in cable slippage.
- Moreover, due to the increasing number of antennas being installed on antenna towers, multiple transmission lines must be strung along the tower to connect to those antennas. Therefore, hangers capable of supporting a plurality of parallel transmission lines were developed. One such example is U.S. Pat. No. 5,794,897 to Jobin et al. This patent discloses a two piece transmission line hanger that is stackable to accommodate a plurality of parallel transmission lines.
- One drawback of current stackable hanger designs, however, is that a considerable amount of installation time is required to attach the two hanger halves around the transmission line(s) and the hanger assembly to the supporting structure. In addition, auxiliary hardware (e.g., screws, bolts, nuts, and washers) is required to secure the hangers to the supporting structure. Moreover, when subsequent transmission lines must be added to accommodate one or more new antennas, the existing two piece stackable hanger assembly has to be unassembled to add another hanger thereto. For instance, the bolt of the first hanger has to be removed, the two hanger halves of another hanger must be placed around the new transmission line(s) and the four hanger halves must be assembled together by inserting a bolt through the hangers and through a hole in the supporting structure and fastening a lock washer and a nut to the bolt. Therefore, there is a need for a novel stackable transmission line hanger that is easy to install, easy to add additional transmission lines thereto, and inexpensive to manufacture.
- The installation of one or more transmission lines along a supporting structure is often a difficult and time-consuming operation because of the large amount of auxiliary hardware required to install some prior hangers and/or the necessity to remove an assembled hanger to add an additional transmission line. Therefore, there is a continuing need for easy to install stackable hangers and for improved methods of installing them. The present invention addresses these needs by providing a one piece, stackable transmission line hanger capable of securing one or more transmission lines. The stackable hanger is expandable to accommodate additional transmission lines without unassembling the prior hanger(s), is expandable to accommodate a large number of transmission line diameters, is inexpensive to produce, and is quickly and easily installed. In addition, the stackable hanger reduces the number of components required to secure one or more transmission lines, reduces installation time, reduces longitudinal movement of the transmission line within each hanger, and allows for simple installation of additional transmission lines.

It should be understood, however, that the invention is not intended to be limited to the particular forms disclosed. Rather, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
- It has been discovered that multiple transmission lines can be efficiently and inexpensively supported by using a one piece, stackable
transmission line hanger 10 according to one embodiment of the present invention. A one piece or unitary hanger is less expensive to produce and more reliable than hangers composed of several pieces. A stackable hanger having two or more pieces that are, for example, welded together, however, would function the same as the unitary hanger described herein. - In one aspect, a stackable transmission line hanger is provided for securing one or more transmission lines to a supporting structure. Each such hanger includes a transmission line retention section for accommodating a transmission line and a mounting section extending from the transmission line retention section. The mounting section supports a mounting hole disposed therein. The
hanger 10 is generally U-shaped and includesarms 11. The transmission line retention section includes afirst leg 14 and asecond leg 16 extending therefrom. The first andsecond legs second legs - One or more of the
hangers 10 can be used to support one or more transmission lines, including circular coaxial cables and waveguides, in generally parallel rows. Thehanger 10 can accommodate a large range of different transmission line diameters. One row of thehangers 10 generally secures one transmission line to a supporting structure, such as a horizontal transmission line bridge or a vertical antenna tower. One or more additional rows of thehangers 10 can secure one or more additional transmission lines by attaching to the respective transmission line hangers in the first row. Thehangers 10 are easy to install because no ancillary hardware is required, such as nuts, bolts, or screws. - The present invention will now be described in connection with the embodiments shown in the drawings. Referring first to
FIG. 1 , thehanger 10 is illustrated. In the illustrated embodiment, thehanger 10 is a unitary structure essentially composed of metal. In one embodiment, thehanger 10 is composed of stainless steel having a thickness of 0.76 mm and is generally U-shaped. The illustratedhanger 10 includes a mountingsection 100, a transmissionline retention section 102, anextended section 104, and anattachment section 106. The mountingsection 100 extends from theretention section 102. The mountingsection 100 includes a snap-in stacking provision, such as a mountinghole 108 disposed therein, as shown inFIGS. 1 and 4 . Theretention section 102 includes two opposingcurved members transmission line 15 which is shown in dotted lines inFIG. 1 . Thecurved members first leg 14 and asecond leg 16, respectively, that comprise theextended section 104. The first andsecond legs curved members compliant area 110 is disposed between the mountingsection 100 and theretention section 102 and allows the first andsecond legs extended section 104 includes a pair ofspring fingers 29 projecting inwardly from theextended section 104 and into theretention section 102, as illustrated inFIG. 2 . Thefirst leg 14 includes one pair ofspring fingers 29 flexibly connected thereto and projecting inwardly therefrom. Thesecond leg 16 includes a second pair ofspring fingers 29 flexibly connected thereto and projecting inwardly therefrom. Thespring fingers 29 are flexibly connected to therespective legs hanger 10, thespring fingers 29 flex outward with respect to therespective legs spring fingers 29 provide spring resistance against the transmission line after it is inserted in thehanger 10. Thespring fingers 29 and thestops 30 help minimize the longitudinal movement of the transmission line in thehanger 10 even on smooth (non-corrugated) transmission lines. Longitudinal movement is defined as movement in a direction parallel to the length of the transmission line. - In another embodiment, illustrated in
FIGS. 12-16 , thespring fingers 29 are not connected at a first andsecond leg spring fingers 29 are connected to and extend from a portion of thecurved members second legs extended section 104 and theattachment section 106. Thus, if theretention section 102 pivots or rocks to one side, theextended section 104 and theattachment section 106 remain centered, which aids in keeping thehanger 10 in place. - Returning to
FIG. 2 , the stackable, snap-inhanger 10 requires no additional hardware to install it to an attachment surface. In contrast, prior hanger assemblies required hardware such as lock washers and nuts to secure a transmission line to a supporting structure. These parts tended to loosen over time with vibration caused by, e.g., wind gusts. Thus, thehanger 10 includes thespring fingers 29 which help to minimize transmission line vibration. In addition, thehanger 10 insures that an improper amount of torque is not applied to a hanger assembly because there is no additional hardware required to fasten thehanger 10 to an attachment surface. - The
compliant area 110, in conjunction with thespring fingers 29, allows thehanger 10 to have the compliance necessary to accommodate a large range of different transmission line diameters. Theextended section 104 also contributes compliance at its curved joint with theretention section 102 to further allow thehanger 10 to accommodate a large range of transmission line diameters and still allow theattachment section 106 to be inserted into an aperture in an attachment surface, such as a supportingstructure 5 or the mountinghole 108 of anotherhanger 10, as shown inFIG. 5 . Prior hangers without an extended section between the transmission line retention section and the attachment section had essentially no compliance. Thus, in these prior designs, if a transmission line larger than the diameter that the transmission line retention section could accommodate was inserted into the hanger, then the attachment section would not be able to be squeezed to allow the attachment section to be inserted into an aperture in, e.g., a supporting structure. - Moreover, the
extended section 104, in conjunction with the pair ofspring fingers 29, allows thehanger 10 to accommodate a large range of different transmission line diameters by having the compliance to expand for larger transmission lines. Theextended section 104 and thespring fingers 29 also have the compliance to allow thehanger 10 to accommodate a large range of transmission line diameters while still allowing theattachment section 106 to be inserted into an attachment surface. - Unlike prior hangers, the shape of the
retention section 102 and theattachment section 106 of thehanger 10 do not change significantly in response to supporting different diameter transmission lines. The flexibility of thespring fingers 29 allows thespring fingers 29 to flex inward with respect to theextended section 104 after a transmission line has been inserted into theretention section 102. The flexibility of theextended section 104 allows theattachment section 106 to be inserted into an aperture in an attachment surface without significantly changing the shape of the transmissionline retention section 102 despite different diameter transmission lines being supported by thehanger 10. - Returning to
FIG. 1 , theattachment section 106 includes afirst section 18 that extends from each of the first andsecond legs second section 20 extends from thefirst section 18 and forms a lockingbarb 22 that is configured to lock against an attachment surface once the lockingbarb 22 is inserted through an aperture in the attachment surface. In one embodiment, the lockingbarb 22 is integral with thesecond section 20 and extends from and is generally orthogonal thereto. Each lockingbarb 22 includes a barb contact point orline 23 for contacting the attachment surface. - In the embodiment of
FIGS. 12-16 , the lockingbarb 22 is integral with thesecond section 20, but also includes a curved folded-overrib 22 a (FIG. 15 ). The folded-overrib 22 a links thesecond section 20 and the lockingbarb 22. The folded-overrib 22 a is curved to provide greater strength to the lockingbarb 22, which increases the ability of the lockingbarb 22 to grasp the edge of the aperture. - In some embodiments, the locking
barb 22 is dimensioned to match the shape of the aperture of the attachment surface. For example, in an embodiment where the aperture is circular, the lockingbarb 22 is curved to match the curvature of the aperture (FIG. 15 ). If the aperture is square, then the lockingbarb 22 is a straight edge to match the side of the aperture. Configuring the lockingbarb 22 to match the shape of the aperture creates astiffer locking barb 22 that is able to better grasp the aperture. -
FIG. 6 shows how theattachment section 106 is secured to the supportingstructure 5 which can include, for example, a horizontal transmission line bridge or a vertical antenna tower. The supportingstructure 5 includes acircular aperture 50 defined by awall 52. Thefirst section 18 contacts thewall 52 at one or both of a pair of contact points 54 and 56. The lockingbarb 22 is configured to lock against the supportingstructure 5 once the lockingbarb 22 is inserted through theaperture 50. The supportingstructure 5 includes anouter surface 58 and aninner surface 60. The surfaces of the supporting structure may be rough due to, for example, irregularities, bubbles, and/or barbs caused by the galvanizing process and/or the punching process that produces theaperture 50. Therefore, thehanger 10 is designed such that each lockingbarb 22 contacts theinner surface 60 of the supportingstructure 5 at the barb contact point orline 23. Because thehanger 10 includes two lockingbarbs 22, one on eachleg hanger 10 can be more securely attached to the supportingstructure 5, despite any irregularities on theinner surface 60. - The
wall 52 of theaperture 50 may also be rough because of irregularities, bubbles, and/or barbs caused by the galvanizing process and/or the punching process that produces theaperture 50. Therefore, in one embodiment, contact with these irregularities is minimized by having thefirst section 18 of thehanger 10 only contact thewall 52 at one or both of the pair of contact points 54, 56, instead of, e.g., a curved surface contacting a large portion of thewall 52. -
FIG. 7 shows how theattachment section 106 is secured to the mountingsection 100 of anotherhanger 10. In one embodiment, the mountingsection 100 includes a square mountinghole 108 disposed therein. The lockingbarb 22 is configured to lock against the mountingsection 100 once the lockingbarb 22 is inserted through the mountinghole 108. The square mountinghole 108 is defined by awall 112 having a pair of opposinglips 114, as shown inFIGS. 2, 4 and 7. The square mountinghole 108 provides an anti-rotation feature that keeps thehangers 10 aligned. Specifically, the lockingbarb 22 includes anotch 116 that is configured to lock against thelip 114 of anotherhanger 10 once the lockingbarb 22 is inserted through the mountinghole 108 and the first andsecond legs notch 116 insures that thesecond row hanger 10 is aligned with thefirst row hanger 10. The alignedhangers 10 insure that the transmission lines secured therein are generally parallel to each other. Thenotch 116 in each lockingbarb 22 insures a secure connection between eachadditional hanger 10. Thenotches 116 lock the distal end of bothlegs lips 114 of the mountingsection 100 of anotherhanger 10, as shown inFIG. 7 . In another embodiment, the lockingbarb 22 has two notches 116 (FIGS. 14 and 16 ) to decrease the likelihood of having the barb disengage thelip 114. - In another embodiment, illustrated in
FIGS. 14 and 15 , the mountinghole 108 is circular in shape and has a lip (or stiffening flange) 115 that encompasses the entire mountinghole 108. By having a lip that encircles the entire mounting hole, the lockingbarb 22 is less likely to disengage from the lip and slip out. - Moreover, adding an additional row of
hangers 10 to a prior row ofhangers 10 produces a “chaining effect.” The resulting assembly ofhangers 10 is not rigid; rather, the assembly is able to flex between the hanger pairs. Therefore, the problems of side loading produced by a rigid hanger assembly attached to an antenna tower are reduced. For example, a rigid assembly acts as a lever arm which reduces the force required to pull the rigid hanger assembly from its supporting structure. With the chaining effect produced by thehangers 10, however, the side loading is distributed through the various attachment and mounting sections of themultiple hangers 10, rather than transferring the entire load back to the base hanger. Therefore, the load is shared by thehangers 10. Thus, thehangers 10 can act as a “spring” during a wind gust rather than as a rigid member. - The
hanger 10 also includes first andsecond legs 17, 19 (FIG. 12 ) that extend down from a portion of thecurved members hangers 10 becoming disengaged during a wind gust. When thehanger 10 is attached to the attachment surface, the first andsecond legs second legs - In another embodiment, shown in
FIGS. 12 and 13 , the first andsecond legs flanges 17 a that are generally orthogonal to the first andsecond legs flanges 17 a act like a brace on the attachment surface if thehanger 10 were to sway due to wind. The out-turnedflanges 17 a are structured to dig into the attachment surface. More specifically, the out-turnedflanges 17 a each include asharp point 17 b that digs into the attachment surface, effectively gripping the surface during high wind gusts. Thus, theattachment section 106 stays centered over the aperture of the attachment surface, keeping the lockingbarbs 22 in place. Also, the out-turnedflanges 17 a along with in-turnedflanges 19a on the first andsecond legs attachment section 106 disengaging from the attachment surface during high winds. - As best shown in
FIGS. 1 and 2 , in one embodiment, thecompliant area 110 is provided by a fulcrum or bend. Thecompliant area 110 enables the first andsecond legs barbs 22 to fit through an aperture in an attachment surface. Thecompliant area 110 also allows the first andsecond legs barb 22 is inserted through the aperture. This expansion brings thefirst section 18 into contact with, e.g., thewall 52 of theaperture 50 at one or both of the pair of contact points 54, 56, as shown inFIG. 6 . Alternatively, this expansion also brings thenotch 116 into contact with thelip 114 of the mountinghole 108 of anotherhanger 10, as shown inFIG. 7 . - The design of the
hanger 10 and, in particular, theextended section 104 allows for easy installation of thehanger 10. Specifically, theextended section 104 allows larger diameter transmission lines to be inserted into thehanger 10. The user then wraps his or her fingers around thehanger 10, and the transmission line therein, and presses thelegs extended section 104 places theretention section 102 further away from the attachment surface, such as the supportingstructure 5 or the mountingsection 100. In addition, theattachment section 106 is closer to the user's fingers and thumb, thus, allowing a greater range of motion and greater force to be applied to thehanger 10 when inserting theattachment section 106 into an attachment surface. Theextended section 104 also gives the user more room to work, and avoids the user's hands from hitting the attachment surface during installation. The mountingsection 100 further extends the distance the user's fingers and thumb are from the attachment surface. - The design of the
hanger 10 and, in particular, theextended section 104 also provides a more dynamic snap-in action than prior hangers when thehanger 10 is installed into an attachment surface. The twolocking barbs 22 also provide less insertion resistance than prior hanger designs having four locking barbs. Having only two lockingbarbs 22 reduces the number of contact points that must contact, for example, theouter surface 58 of the supportingstructure 5 during insertion of thehanger 10 into the supportingstructure 5. Additionally, the two barb design of theattachment section 106 reduces insertion resistance by reducing the cam pressure required and the amount of deflection required to insert thehanger 10 into an attachment surface. This reduces the amount of force required to insert thehanger 10 into, for example, a supporting structure or a mounting section of anotherhanger 10. Thehanger 10, thus, requires less manual dexterity to install and uninstall than prior hangers. In addition, the ergonomic design of thehanger 10, including theextended section 104, allows for easier installation. These are important features, especially where the typical transmission line is in excess of 1,000 feet and a hanger is mounted every three feet. Consequently, hundreds of hangers must be installed to support such a transmission line. The hours required to install that many hangers is great. Accordingly, transmission line installation is costly. In addition, it can be difficult to find someone willing to install transmission line hangers high above the ground, especially if extra hardware is required to install the hangers. Therefore, a hanger that requires less installation time and is easier to install reduces the number of hours required for installation, thus, reducing installation costs. - In another embodiment, the
extended section 104 includesspring finger 29 projecting inwardly from theextended section 104 and into theretention section 102. For example, thefirst leg 14 may include thespring finger 29 flexibly connected thereto and projecting inwardly therefrom. Thespring finger 29 is flexibly connected to thefirst leg 14 such that when a transmission line is inserted into thehanger 10, thespring finger 29 flexes outwardly with respect to thefirst leg 14 and forces the transmission line against thetransmission line stop 30 on the opposingleg 16. - Thus, the
spring finger 29 can provide spring resistance against the transmission line after it is inserted in thehanger 10. Thespring finger 29 also bites into the jacket of the transmission line to further secure the transmission line within thehanger 10. Thespring finger 29 and thestops 30 help minimize the longitudinal movement of the transmission line in thehanger 10 even on smooth (non-corrugated) transmission lines. Thespring finger 29 also helps minimize transmission line vibration. Alternatively, thesecond leg 16 may include thespring finger 29 flexibly connected thereto and projecting inwardly therefrom that forces the transmission line against the righttransmission line stop 30. In either case, theextended section 104, in conjunction with thespring finger 29, allows thehanger 10 to accommodate a large range of different transmission line diameters by having the compliance to expand for larger transmission lines. Theextended section 104 and thespring finger 29 also have the compliance to allow thehanger 10 to accommodate a large range of transmission line diameters while still allowing theattachment section 106 to be inserted into an attachment surface. - In some embodiments, the transmission line stops 30 and
spring fingers 29 are also configured to adapt to a large range of transmission line diameters. The transmission line stops 30, as shown inFIG. 13 , are flat and extend relatively straight fromcurved members hanger 10 to accommodate a greater range of transmission line diameters while still allowing theattachment section 106 to be inserted into the attachment surface. - In the illustrated embodiments, no matter how the transmission line is disposed in the
hanger 10, the opposingspring fingers 29 will provide spring resistance against the transmission line which, in turn, will force the transmission line against the pair of opposing transmission line stops 30 and bite into the jacket of the transmission line. - In use, the
hanger 10 may be installed easily and quickly by pulling apart thelegs hanger 10 over the transmission line such that thecurved members spring fingers 29 are forced against the transmission line, thus, pressing the transmission line against the opposing transmission line stops 30. Thelegs locking barbs 22 to be inserted through an aperture in an attachment surface, such as the supportingsurface 5, as illustrated inFIG. 9 . Thehanger 10 is inserted into theaperture 50 until thefirst sections 18 snap into contact with the supportingstructure 5 at one or both of the pair of contact points 54, 56 and thebarb contact point 23 contacts theinner surface 60 of the supportingstructure 5, as illustrated inFIG. 6 . This process is repeated for eachhanger 10 that is installed into the supportingsurface 5 along the length of the transmission line. Likewise, thelegs locking barbs 22 to be inserted through the mountinghole 108 in the mountingsection 100 of anotherhanger 10, as illustrated inFIGS. 5 and 7 . Then, thelegs compliant area 110 expands thelegs notch 116 of each lockingbarb 22 locks against thelip 114, as best illustrated inFIG. 7 . This process is repeated for eachhanger 10 that is installed as an additional row onto a previously installed hanger(s) 10. Thus, each additional transmission line run that is added to, e.g., an antenna tower is independent of the previous transmission line run. In other words, eachadditional hanger 10 can be installed independently of, and without unassembling, the prior hanger(s) 10. - The
hanger 10 can also be readily uninstalled and reused in another location. To uninstall thehanger 10, thelegs locking barbs 22 to be removed from the attachment surface. Next, theretention section 102 is slipped off the transmission line by pulling apart thelegs spring fingers 29 from the transmission line jacket. - In another embodiment, the transmission
line retention section 102 includes areas ofresistance 25 for retaining the transmission line and accommodating a large range of transmission line diameters.FIGS. 10 a, 10 b, 11 a, and 11 b illustrate two embodiments of the areas ofresistance 25, as shown in a non-stackable embodiment of thehanger 10. It will be appreciated, however, that the areas ofresistance 25 can be incorporated into thestackable hangers 10 illustrated inFIGS. 1-9 . -
FIGS. 10 a and 10 b illustrate two opposing areas ofresistance 25′ that each include an inwardlycurved portion 26′ and anindentation 28′. Thecurved portion 26′ is attached to theretention section 102 at each end and provides spring resistance against the transmission line after it is inserted in thehanger 10. Theindentations 28′ help further secure the transmission line within thehanger 10 by penetrating or biting into the jacket of the transmission line. Thus, theindentations 28′ minimize the longitudinal movement of the transmission line in thehanger 10 and also help minimize transmission line vibration. -
FIGS. 11 a and 11 b illustrate two opposing areas ofresistance 25″ that each include an inwardlycurved portion 26″ and a pair oftabs 28″. Thecurved portion 26″ is attached to theretention section 102 at each end and provides spring resistance against the transmission line after it is inserted in thehanger 10. The inwardlybent tabs 28″ help further secure the transmission line within thehanger 10 by penetrating or biting into the jacket of the transmission line. Thus, thetabs 28″ minimize the longitudinal movement of the transmission line in thehanger 10 and also help minimize transmission line vibration. - Having two opposing areas of resistance makes the orientation of the transmission line inserted into the
hanger 10 irrelevant. No matter how the transmission line is disposed in the hanger 10 (e.g., the areas of resistance are between the corrugations of a corrugated cable or are in contact with one of the protruding corrugations), the two opposing areas ofresistance 25 will provide spring resistance against the transmission line and theindentation 28′ ortabs 28″ will penetrate into the jacket of the transmission line. - The present invention provides a one piece, stackable transmission line hanger that is inexpensive to produce. For example, the typical cost of a traditional hanger capable of holding three transmission lines is about three times greater than the cost for three ⅞″ diameter stackable hangers 10 (this estimate depends on the style and amount of hardware required for the traditional hanger). Moreover, the
additional hangers 10 do not need to be bought until the additional transmission line runs are added. Thus, the extra cost for theadditional hangers 10 can be deferred until the additional transmission line runs are actually installed. - Therefore, the present invention provides a stackable transmission line hanger capable of securing one or more transmission lines to an attachment surface. The stackable hanger is expandable to accommodate additional transmission lines without disassembling the prior hanger(s), is expandable to accommodate a large number of transmission line diameters, is inexpensive to produce, and is quickly and easily installed. In addition, the stackable hanger reduces the number of components required to secure one or more transmission lines, reduces installation time, reduces longitudinal movement of the transmission line within each hanger, and allows for simple installation of additional transmission lines.
- While the present invention has been described with reference to one or more particular embodiments, those skilled in the art will recognize that many changes may be made thereto without departing from the spirit and scope of the present invention. Each of these embodiments and obvious variations thereof is contemplated as falling within the spirit and scope of the claimed invention, which is set forth in the following claims.
