1. Field of the Invention
This invention relates generally to apparatus for terminating generally horizontally elongated fencing elements such as metal wires that may be subjected to a longitudinal tension, and in particular to the termination of multi-strand wire ribbons including an extruded polymeric intermediate matrix portion bonding at least two metal strands together.
2. Background of the Invention
A fence can be formed to have a plurality of posts situated in substantially fixed spaced relation to each other. One or more longitudinal fencing elements can be located between the plurality of posts to define a barrier between regions on opposite sides of the fence. Where the longitudinal fencing elements are formed of wire or wire composites, the wire or wire composite is typically placed under some tension using a fence tensioner or tightener at one or both ends of the wire or wire composite. Examples of fence tensioners are to be found, for example, in U.S. Pat. Nos. 6,648,305; 6,848,678; and D503,609, and the prior art cited therein. In many installations, the use of a fence tensioner or tightener on both ends of each longitudinal fencing element can be an unnecessary expense that is desirably avoided. Where the longitudinal fencing element is simply a single strand of wire, or a small number of spirally wound wires, one end of the longitudinal fencing element can simply be looped around a post and the end wrapped as shown, for example in U.S. Pat. No. 499,279. Such a loop and wrap is rendered more difficult if not impossible where the longitudinal fencing element is a wire and polymer composite ribbon as shown, for example, in U.S. Pat. Nos. 4,465,263; 4,860,996; 4,881,721; and 6,834,846.
Apparatus for coupling a terminal end of a wire strand to a fence post are known, for example, from U.S. Pat. Nos. 579,918; 3,439,898; 4,266,756; and 6,578,342. The coupling of a terminal end of a wire and polymer composite ribbon to a post is illustrated in
A termination bracket for a fence that can be used in connection with composite ribbon fencing can include a longitudinal channel member including a first main surface and a pair of outwardly protruding sides extending along opposite edges of the first main surface. A clasp member can extend laterally at least part way between the two sides. The clasp member can be spaced from the first main surface of the longitudinal channel member. The clasp member can define one or more openings. The openings can be defined between the clasp member and the longitudinal channel member. A vice element can be situated in each opening, the vice element being adapted to capture an end of the longitudinally extending composite wire ribbon fencing.
In one termination bracket the clasp member can extend laterally continuously between the two outwardly protruding sides generally perpendicular to the first main surface of the longitudinal channel member. The clasp member can include one or more openings. A vice element can be situated in each opening, the vice element being adapted to capture an end of a longitudinally extending wire protruding from an end of the composite ribbon fencing.
The first main surface can include at least one opening for receiving a fastener for fastening the termination bracket to a fixed fencing support member. The fastener opening can be sized to receive a grommet. The outwardly protruding sides and the first main surface can be a unitary one-piece structure. The clasp member can also be unitary with the outwardly protruding sides. Each of the outwardly protruding sides can include a slot receiving an end of the clasp member. The slots receiving the lateral ends of the clasp member can be situated substantially midway between first and second ends of the outwardly protruding sides. The clasp member can be fixed to the first main surface. The termination bracket can be used in conjunction with a wire and polymer composite ribbon having a width substantially equal to the spacing between the outwardly protruding sides.
In another termination bracket, a longitudinal channel member includes a first main surface and a pair of outwardly protruding sides extending along opposite edges of the first main surface, with a clasp member being defined by portions extending laterally inwardly part way from the protruding sides toward the middle of the bracket. The clasp member defines a single opening between the clasp member and the first main surface of the longitudinal channel member. A vice element can situated in the opening, the vice element being adapted to capture an end of a longitudinally extending fencing element between the vice element and the first main surface.
Various features and advantages will become readily apparent to those skilled in the art from the following detailed description of preferred embodiments of the present invention, including the best mode of practicing the present invention, which are illustrated in the accompanying drawings. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Moreover, in the figures, like referenced numerals designate corresponding parts throughout the different views.
The first main surface 16 is shown in
As in the first embodiment, the clasp member 26 of the second embodiment includes a plurality of openings 28, each opening being sized to receive a wire vice element 30. The vice elements 30 are adapted to capture an end 32 of a longitudinally extending wire 34 protruding from the polymer composite 36 of the fencing element 12. The wire and polymer composite ribbon 12 is shown to have a width W substantially equal to the spacing between the outwardly protruding sides 18 and 20. The forward edge 38 of termination bracket 10′ has a blunt end appearance, with only a single first opening 42 that can be used for receiving a fastener 46, as shown in
A vice element 78 is shown to comprise a back portion 80 and two depending sides 82 and 84. Depending side 82 is seen in
The components of the termination bracket 10″ can be manufactured from steel or another metal of sufficient strength and durability, which desirably can be galvanized and/or powder coated. The vice element 78 can be caused to disengage from the composite fencing ribbon 12 by hammering depending side 82 between the inner edges 76 of the clasp elements 68 in the direction of forward edge 72. The outwardly protruding sides 18, 20 and the first main surface 16 can be a unitary one-piece structure that can be formed, for example, from steel, fiberglass filled nylon or other high-strength engineering plastic.
While these features have been disclosed in connection with the illustrated preferred embodiments, other embodiments of the invention will be apparent to those skilled in the art that come within the spirit of the invention as defined in the following claims.
