Description:
SPECI FICATION

AERIAL CABLE SPACER

The present application relates in general to spacing device but more particularly to an aerial cable spacer which will support power, telecommunication, CATV and similar cables in organized arrays while attached to a supporting messenger cable. Variations of this device can be adapted to secure other materials besides just wires, such as surgical tubing or other generally linear materials, can accommodate a large variety of different materials in a single configuration (e.g., different wire sizes and/or types), and can be mounted by other means than a messenger cable or utilized without mounting hardware. In placing aerial mounted cables as in the case of installing electrical cables and telephone and other communication systems on elevated poles, it is necessary or desirable to provide a spacing mechanism for holding several cables in fixed position relative to one another both vertically and horizontally. This is generally accomplished by use of plastic spacers which mount to a messenger wire (steel tensioning cable) and provide receptacles for holding 3-4 cables discretely separated from each other. Such spacers are generally designed for use with medium to high voltage cables. One such system has been identified in the literature specifically designed for use with low voltage power cables and telephone cables. This is described in US 4,646,433A issued on March 3, 1987 entitled "Devices for Attaching One or a Number of Aerial Cables Thereto" which describes a cable-attachment spacer for securing one or a number of suspended cables to a suspension cable. While this system does provide a means for individual access to suspended wires, it does not provide the key features of the present l application and hence does not address the primary concerns for which the present application is designed. US 4,646,433A only provides for a limited number of cables at a time, typically from 1 to 5 cables per suspension cable, and requires removal of separate component to gain access to suspended wires for placement or removal. Extending this design concept to allow for large numbers of cables as in the present requirement is not feasible or practical. To resolve its drawbacks, there is a need for a cable spacer which will provide the ability to discretely mount a large number of such cables in a manner which allows ready access to individual cables without disturbing adjacent wires. The present application serves to secure up to 60 cables at a time, in discreet bundles, with individual wires readily accessible without the removal or addition of any loose components in service.

It is therefore the main object of the present application to provide for a cable spacer which comprises a modular design so that it can be easily adapted to a wide variety of cable quantities and types while maintaining ready access to individual wires without disturbing adjacent wires.

Another object of the present application is to provide a cable spacer which has vertical connectors that allow for connecting either a pair of cable holding modules or a single module in a centered manner.

Another objective of the present application is to provide a cable spacer capable of resisting long-term exposure to high levels of ultraviolet radiation, heat, rain and high winds. Another objective of the present application is to provide a spacing device that can be adapted to hold a wide variety of linear materials in a variety of applications.

Another objective of the present application is to provide a cable spacing system that can accommodate a variety of cable types and sizes either uniformly or in a combined state.

Still another object of the present application is to provide a cable spacer wherein the design of which allows for an anti-vandal version that resists being opened except when using a special tool.

Other objects and advantages of the present application will be highly appreciated and be easily understood upon reading the detailed description taking into consideration the appended drawings wherein;

In use, a hanger 41 is placed over a messenger wire or suspending support cable "M" and cable holding block bodies are interconnected to it, with the corresponding protrusions 25, 25a and receptacles 26, 26a being aligned and the components are pushed together forming an interconnected aerial cable spacer 100. When the hinged side of the block bodies is in its closed position the protrusion on the locking mechanism or means 33 prevents components from becoming misaligned or separating laterally. With such, the connected components provide a passageway "P" wherein the cable "C" to be held and spaced is being received thereon.

Said protrusion 25, 25a, 25b are being defined by a T-shaped rib having filleted edges all around. Said concavities 29, 32 opening also has filleted or chamfered edges at its openings on both sides. When a protrusion is aligned with a corresponding opening and pressed together the tapered edges of both components cause the protrusion to slide into the receptacle thereby creating an interlocking joint. The pressure caused by the compression within the material of the protrusion provides a grip such that the spacers tend to remain interlocked with their neighbors while the protrusion on the locking mechanism of the cable holding block when closed interlocks with the cavity on the bottom of the above hanger or other cable hanging mechanism (CHM) thereby preventing any lateral movement of the components. The shape and positioning of the protrusions serve to hold the components in direct contact with each other without the need for any additional components. To separate components requires only to unlock the hinged side and slide the components laterally apart.

With such arrangement, a desired number and configuration of cable holding spaces could be conveniently formed by interconnecting a series of CHM's with their hanger.

Upon assembly, corresponding cables "C" are placed within the ovate passageways "P" and then the hinged side wall or cable locking and retaining member 30 is closed and locked. With a plurality of spacers placed upon the messenger wire at suitable intervals the cables are able to be supported while remaining easily accessible.

This entire hanger mechanism can alternatively be substituted with a hanger utilizing the same lower interconnecting shapes (T-shaped, V- shaped, C or circular shaped, etc), but with upper sections that are designed to be bolted, screwed, welding, riveted or otherwise attached to walls, ceilings, beams and similar structures, mounted horizontally, vertically or in any other orientation.

With the foregoing it is desired that the present application seeks to protect all novel features of the subject application as illustrated in the above embodiments including all modifications that may be obvious to those persons skilled in the art derived thereof.
