Cable Hangers

Patent No. US11979008 (titled "Cable Hangers") was filed by Affordable Wire Management Llc on Apr 15, 2021.

What is this patent about?

’008 is related to the field of cable management, specifically cable hangers used in energy production and transmission infrastructures like solar power plants. These hangers support cables above ground, ensuring they are secure and can withstand harsh environmental conditions. Existing cable hangers often use passive attachments that can become unsecured in high winds or degrade under UV exposure, leading to cable displacement and safety issues. The invention addresses these shortcomings by providing a more robust and versatile cable hanger system.

The underlying idea behind ’008 is to create a modular cable hanger system that can be easily expanded and adapted to different cable configurations. This is achieved by using a main support member with a hanging mechanism and an attachment mechanism, combined with saddle extensions that can be added or removed as needed. The hanging mechanism is designed to securely attach to a support wire, while the attachment mechanism allows for the connection of saddle extensions to increase the cable-carrying capacity of the hanger.

The claims of ’008 focus on a cable hanger comprising a support member with a proximal end (having a hanging mechanism) and a distal end (having an attachment mechanism), a first saddle, a second saddle larger than the first saddle, and at least one saddle extension. The saddle extension includes a central post with at least one saddle, a securement mechanism to attach to the cable hanger's attachment mechanism, and another attachment mechanism on its distal end. The attachment mechanism is positioned completely below the first and second saddles and extends downward from the bottom surface.

In practice, the cable hanger is first attached to a support wire using the hanging mechanism, which can be a hook or a similar device. Then, saddle extensions are connected to the attachment mechanism on the distal end of the support member. These extensions provide additional saddles for supporting more cables. The securement mechanism can be clips, bolts, or deformable tabs, allowing for easy installation and removal of the extensions. This modular design allows the cable hanger to be customized to the specific needs of the installation, and expanded later if needed.

The key differentiation from prior approaches lies in the modularity and expandability of the cable hanger system. Unlike traditional cable hangers with fixed capacity, this invention allows for on-demand addition of saddle extensions , providing flexibility in cable management. The offset hanging mechanism ensures balance even with added extensions, preventing rotation and maintaining stability. Furthermore, the secure attachment mechanisms and robust materials enhance the system's resistance to environmental factors, improving its reliability and lifespan compared to existing solutions.

How does this patent fit in bigger picture?

Technical landscape at the time

In the early 2020s when ’008 was filed, above-ground cable management in energy production and transmission infrastructures was typically implemented using various types of cable hangers to support cables in a secure manner. At a time when systems commonly relied on physical hardware solutions rather than purely software-based solutions for cable support, hardware or software constraints made designing cable hangers capable of withstanding harsh environmental conditions non-trivial.

Novelty and Inventive Step

The claims were subject to rejections under 35 U.S.C. 103. Arguments were presented by the applicant, and some rejections were withdrawn. However, a new ground of rejection was made in view of 35 U.S.C. 103. The Office action was made final. The prosecution record does NOT describe the technical reasoning or specific claim changes that led to allowance.

Claims

This patent contains 14 claims, with claim 1 being the only independent claim. Independent claim 1 is directed to a cable hanger comprising a support member, hanging mechanism, attachment mechanism, first and second saddles, and at least one saddle extension. The dependent claims generally elaborate on specific features and variations of the cable hanger described in the independent claim, such as the securement mechanism, saddle arrangements, and hanging mechanism details.

Key Claim Terms New

Definitions of key terms used in the patent claims.

Term (Source)Support for SpecificationInterpretation
Attachment mechanism
(Claim 1)
“For example, an attachment mechanism can be arranged on the distal end of the support member. In some implementations, the attachment mechanism can be a loop configured to attach with a hanging mechanism of a cable hanger.”A component located on the bottom surface at the distal end of the support member.
First saddle
(Claim 1)
“A plurality of saddles are attached to and extend from the support member, with each saddle of the plurality of saddles being configured to support at least one cable on a cable supporting surface. The plurality of saddles can vary in numerous ways. For example, the plurality of saddles can form at least one mirrored pair of saddles along the support member from the proximal end to the distal end.”A component arranged on the support member that supports at least one cable.
Hanging mechanism
(Claim 1)
“A hanging mechanism is arranged at the proximal end of the support member, where the hanging mechanism is offset on the support member. The hanging mechanism can have various configurations. For example, the hanging mechanism can be a positive locking mechanism configured to secure the cable hanger to a support wire.”A component located at the proximal end of the support member that attaches the cable hanger to a support wire.
Saddle extension
(Claim 1)
“At least one saddle extension includes a central post having a proximal end and a distal end. At least one saddle is attached to the central post and configured to support at least one cable. A securement mechanism is arranged on the proximal end and configured to attach the saddle extension to the attachment mechanism of the cable hanger, and an attachment mechanism is arranged on the distal end.”A component including a central post, at least one saddle, a securement mechanism, and an attachment mechanism.
Support member
(Claim 1)
“In one aspect, a system for cable hangers is provided that in some implementations includes a cable hanger having a support member including a proximal end and a distal end. A plurality of saddles are attached to and extend from the support member, with each saddle of the plurality of saddles being configured to support at least one cable on a cable supporting surface.”A component of the cable hanger with a proximal and distal end, used to support other components.
