TECHNICAL FIELD

The present invention relates generally to the field of products for use on animals, and more particularly to a device for restricting the intake of forage for a grazing animal.

BACKGROUND ART

Muzzles for grazing horses are known. The existing designs are relatively heavy, expensive to manufacture, and many cause irritation to the skin of the horse which requires extra padding or wrapping the surface of the muzzle to hinder rubbing. Some of the designs are rigid and need to be heated and formed to the shape of the horse. What is needed is an improved design that addresses the many drawbacks with existing muzzles.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

At the outset, it should be clearly understood that like reference numerals are intended to identify the same structural elements, portions or surfaces consistently throughout the several drawing figures, as such elements, portions or surfaces may be further described or explained by the entire written specification, of which this detailed description is an integral part. Unless otherwise indicated, the drawings are intended to be read (e.g., cross-hatching, arrangement of parts, proportion, debris, etc.) together with the specification, and are to be considered a portion of the entire written description of this invention. As used in the following description, the terms “horizontal”, “vertical”, “left”, “right”, “up” and “down”, as well as adjectival and adverbial derivatives thereof, (e.g., “horizontally”, “rightwardly”, “upwardly”, etc.), simply refer to the orientation of the illustrated structure as the particular drawing figure faces the reader. Similarly, the terms “inwardly” and “outwardly” generally refer to the orientation of a surface relative to its axis of elongation, or of rotation, as appropriate.
Referring to FIG. 1, merely for the purposes of illustration and not by way of limitation, the present embodiment provides a grazing restrictor 10. The grazing restrictor 10 may be constructed as a unitary, flat member having a body portion 13 located toward the center of the restrictor 10. A central opening 16 may be disposed at the approximate center of the device. A plurality of elongate segments 19 a-19 h may extend in multiple directions from the body portion 13. Segment 19 a extends upward from the body portion 13 of the restrictor 10. Segments 19 b-19 d extend to the right of the body portion 13. Segment 19 e extends downward from the body portion 13 and may be disposed in the opposite direction from Segment 19 a. Segments 19 f-19 h extend to the left of the body portion 13 and may be disposed opposite from Segments 19 b-19 d. Ventilation openings 22 may be formed in segments 19 a and 19 e. Additional ventilation openings may be provided in the body portion 13 or in the segments 19 a-19 h.
A plurality of openings 25 may be disposed in the segments 19 a-19 h. The openings 25 on each segment 19 a-19 h may be arranged in linear fashion from a first opening 25 disposed closer to the center of the device to a last opening 25 disposed near a distal end 28 of the respective segment.
The restrictor 10 may be formed from an elastomer such as a thermoplastic urethane or similar plastic polymer or other thin, lightweight material having elastic properties. The material is preferably mildew and UV resistant. For example, the restrictor 10 may be formed from a polyether urethane film or sheet. The film/sheet may be approximately 2-5 mm thick. Other thicknesses of film or sheet may also be suitable. The restrictor 10 may be die cut to form a unitary member. The restrictor may be approximately twenty (20) to twenty-eight (28) inches in diameter. The restrictor 10 may be formed from a thin, lightweight and elastic material that is capable of laying flat as shown in FIG. 1. The restrictor 10 may be formed from an elastic material such that when it is removed from the state shown in FIGS. 2-4, it returns to its original flat shape shown in FIG. 1. The restrictor 10 may be formed from a clear material and may be provided with a plurality of openings to increase ventilation.
Turning to FIGS. 2-4, the elongate segments 19 a-19 h can be folded upward (i.e., normal to the page with respect to the orientation shown in FIG. 1) from the end of the body portion 13 to from a muzzle for mounting around the mouth of a horse 31. Although the restrictor 10 is shown in connection with a horse 31, the restrictor 10 may be configured and arranged for use with other animals. The muzzle is formed by attaching the elongate segments 19 a-19 h to a halter 34 by means of low profile cable ties 37 that may be inserted through the openings 25. The cable ties 37 are one example of elongate members having a first end and a second end configured to extend through the openings 25 in the elongate segments 19 a-h and around the halters 34 and to connect in end to end fashion to attach the restrictor 10 to the halter 34. Other elongate members constructed from materials such as cloth or fabric or other flexible materials having connecting means at opposite ends may also be suitable. The fasteners at the ends of the elongate members may include buttons, quick connect couplings, or the like or could be attached by hook and loop fasteners. Alternatively, the opposite ends of the elongate member could be tied together. The restrictor 10 is adjustable by means of the plurality of openings 25. As best shown in FIG. 4, the arrangement of the openings 25 in a line provides for a single size for the restrictor 10 configured for use with various sizes of animals and halters.
The present invention also provides a combination that includes a halter 34 and a grazing restrictor 10 configured and arranged to be mounted thereon. The restrictor 10 comprises a body portion 13 surrounding a central opening 16. The central opening 16 is sized to provide a throughput restriction on the amount of forage ingested while grazing. A plurality of elongate segments 19 a-19 h extend outward from the body portion 13. The plurality of elongate segments 19 a-19 h have a plurality of openings 25 defined therein. The plurality of elongate segments 19 a-19 h are capable of being folded upward relative to the body portion 13 to form the shape of a muzzle. The body portion 13 and the plurality of elongate segments 19 a-19 h are formed from a unitary, elastic member capable of laying flat in a first configuration and then being folded into the shape of a muzzle in a second configuration.
The present invention provides many advantages including reduced weight and increased ventilation. The open design of the restrictor 10 allows for more airflow which inhibits bacterial growth. Also, the spring-like properties of the restrictor 10 provide that when the restrictor 10 is attached to the halter 34 the elongate segments 19 a-h are configured and arranged such that they are biased away from the halter 34. As a result, the spring-like properties of the elastic materials used for construction keep the restrictor 10 from laying on the nose of the horse 31 thereby preventing and or reducing rubbing and irritation. The spring-like properties of the restrictor 10 also provide for minimal skin contact on any portion of the horse 31.
