Description
Background of the Invention
The present invention relates to an electric fence insulator and, more particularly, an insulator capable of attachment to a rectangular fence post or rail by simply snapping together a pair of brackets.
Various devices for mounting insulators to fence posts are known in the prior art and operate to support an electric fence wire or ribbon.
Although assumably effective in operation, the known devices for mounting insulators exhibit several disadvantages. Some known devices are only mountable to or around the top of a fence post or are incapable of being mounted at any desired elevation along the fence or fence post. Further, devices which are mounted using nails, bolts, or staples are undesirable because they are not easily removable or adjustable. Nail or like-mounted insulators are also destructive to the increasingly popular molded plastic fence posts and rails. Finally, existing insulator mounting devices are generally designed for round or T-shaped posts and do not efficiently accommodate rectangular posts and rails. Thus, it is desirable to have an insulator for holding a wire or ribbon for an electric fence that is easily mountable and adjustable at any position on rectangular fence posts or rails of various sizes.
Summary of the Invention
Accordingly, it is a primary object of this invention to provide an insulator which may be mounted on a rectangular fence post or rail for supporting an electrically charged wire or ribbon.
Another object of this invention is to provide an insulator, as aforesaid, which may be mounted without the aid of any penetrating hardware such as nails, bolts, or staples.
Yet another object of this invention is to provide an insulator, as aforesaid, which may be mounted at any desired position or elevation on a rectangular fence post or rail.
A further object of this invention is to provide an insulator, as aforesaid, which is adjustable to accommodate a plurality of rectangular post sizes.
A still further object of this invention is to provide an insulator, as aforesaid, having rubberized pads within the mounting means that provide friction and grip to securely hold a mounted insulator in place.
A still further object of this invention is to provide an insulator, as aforesaid, which is easily mounted, adjusted or removed without damaging the fence post or rail.
A particular object of this invention is to provide an insulator, as aforesaid, that is simple and inexpensive to produce and that is aesthetically pleasing in appearance.
Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.
These objects are attained by providing an insulator which mounts to a rectangular fence post or rail without penetrating the post or rail with any other hardware such as nails, bolts, or staples. The insulator utilizes a pair of brackets that can be positioned about any location on a rectangular fence post or rail and then snappably secured thereto. The bracket assembly is snappably adjustable to accommodate a plurality of rectangular post or rail sizes and to facilitate simple and non-destructive removal of an insulator. The need for additional hardware or assembly is further eliminated by the insulator body and electric wire support member being integrally attached to one bracket.

Description of the Preferred Embodiment
Turning more particularly to the drawings, FIGS. 1-3 show the preferred embodiment of the insulator 100 having a first 200 and second bracket 300 for attachment about a rectangular fence post 500 or rail. The insulator 100 is preferably constructed entirely of a synthetic plastic with the exception of the rubberized pads 102. As illustrated in FIGS. 1-6, a first bracket 200 comprises an identical pair of oppositely disposed parallel arms 202 integrally connected at proximal ends 204 to a front member/web 206 perpendicularly intermediate said arms 202.
An insulator body 400 having an elongated construction is integrally joined to a front side 208 of the front web 206, said insulator body 400 decreasing in both height and width while forwardly extending to integrally conjoin a vertically disposed plate 402. A wire support member 410 is integrally joined to a point near the bottom of a front side 404 of the plate 402, said wire support member 410 having a first panel 412 upwardly and outwardly extending from the plate 402 at a 45.degree. angle to a second panel 414 parallel to the plate 402. A third panel 416 upwardly and inwardly extends from the second panel 414 at a 45.degree. angle to a top panel 418 perpendicularly overlapping a top side 406 of the plate 402. It is understood that the top panel 418 is not attached to the top side 406 of the plate 402.
In function, a slit 420 is formed between the top panel 418 of the wire support member 410 and the top side 406 of the plate 402 through which an electrically charged wire 510 or ribbon may easily be inserted. The overlapping construction also provides for efficient retention of the electric wire or ribbon 510. It is further understood that the plate 402 and second panel 414 of the wire support member 410 are parallel to one another and thus cooperate to maintain proper alignment and support of an electrical wire or ribbon 510 passing therebetween.
Each arm 202 of the first bracket 200 includes upper 210 and lower 212 outwardly extending flanges, each flange 210, 212 having a plurality of linearly spaced annular holes 214 therethrough to which the second bracket 300 may be snappably secured. The second bracket will be further described later. Each hole 214 in an upper flange 210 is connected by an imaginary vertical axis with a hole 214 in a lower flange 212. It is understood that while the illustrated embodiment shows two pairs of holes 214 in each flange 210, 212, thus representing two fence post size adjustments, the insulator described herein may contain additional holes to accommodate other post sizes. A channel 216 is formed between the upper 210 and lower 212 flanges through which post housings 310 on the second bracket 300 may be slidably inserted, said post housings being further described later. The first bracket 200 further includes a groove 218 interiorly disposed on and spanning the length of each arm 202, said groove 218 providing a track for receiving the arms 302 of the second bracket 300 as described below. Slots 220, 222 are vertically disposed in the front member 206 to receive the arms 302 of the second bracket 300 therethrough when certain adjustments of the insulator are preferred.
Turning to FIGS. 7-9, the second bracket 300 is now more specifically described. The second bracket 300 comprises an identical pair of oppositely disposed parallel arms 302 integrally connected at ends 304 to a back member/web 306 perpendicularly intermediate said arms 302. Each arm 302 of the second bracket 300 includes an exteriorly positioned post housing 310 having a pair of posts 312 extending upwardly and downwardly therefrom. The arms 302 of the second bracket 300 and the groove 218 formed in the arms 202 of the first bracket 200 are equal in height. Thus, the arms 302 of the second bracket 302 are slidably insertable into said groove 218 and through the slots 220, 222 in the front member 206 until the posts 312 are snappably secured in the desired holes 214 in the flanges 210, 212. It is understood that the flanges 210, 212 are sufficiently flexible to allow the posts 312 to slide freely through the channel 216 to the desired position before being secured.
Rubberized pads 102 may be fixedly attached to the interior sides 207, 307 of the front and back members 206, 306. Said rubberized pads 102 provide friction and grip to enhance maintenance of the positioning of an insulator 100 mounted on a smooth fence post or rail.
Accordingly, it can be seen that the insulator 100 is easily mountable or adjustable to any position on rectangular fence posts or rails of various sizes. In addition, the insulator requires no additional hardware for installation and is non-destructive to the fence post or rail.
It is to be understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
