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.
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.
The present invention meets the above described need by providing a grazing restrictor (10) for attaching to a halter (34). The restrictor (10) includes a body portion (13) surrounding a central opening (16). A plurality of elongate segments (19a-19h) extend outward from the body portion (13). The elongate segments (19a-h) have a plurality of openings (25) defined therein. The elongate segments (19a-h) are capable of being folded upward relative to the body portion (13) to form the shape of a muzzle.
A plurality of ties (37) have a first end capable of being inserted through one or more of the openings (25) in the elongate segments (19a-19h) and a second end capable of extending around the halter (34) and being connected to the first end in end to end fashion such that the restrictor (10) is capable of being supported by the halter (34).
In one aspect, the body portion (13) and elongate segments (19a-19h) are formed as a unitary member.
In one aspect, the body portion (13) and elongate segments (19a-19h) are formed from an elastic material.
In yet another aspect, the body portion (13) and elongate segments (19a-19h) are constructed of polyether urethane.
In an additional aspect, the restrictor (10) may further comprise a plurality of ventilation openings (22) formed in one of the body portion (13) and the plurality of elongate segments (19a-19h).
In another aspect, the plurality of elongate segments (19a-19h) may further comprise finger-like projections having rounded edges.
In another aspect, the plurality of ties (37) comprise low profile cable ties.
In yet another aspect, the restrictor (10) further comprises one or more ventilation openings (22) in the body portion (13).
In another aspect, the restrictor (10) further comprises one or more ventilation openings (22) in the plurality of elongate segments (19a-19h).
In another aspect, the central opening (16) is sized to provide a throughput restriction on the amount of forage ingested while grazing.
In yet another aspect of the invention, a grazing restrictor (10) is configured for attaching to a halter (34). 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 (19a-19h) extend outward from the body portion (13). The plurality of elongate segments (19a-19h) have a plurality of openings (25) defined therein. The plurality of elongate segments (19a-19h) are capable of being folded upward relative to the body portion (13) to form the shape of a muzzle. A plurality of ties (37) have a first end capable of being inserted through one or more of the openings (25) in the elongate segments (19a-19h) and a second end capable of extending around the halter (34) and being connected to the first end such that the restrictor (10) is capable of being supported by the halter (34) on the horse (31).
The body portion (13) and the plurality of elongate segments (19a-19h) 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. In another aspect of the invention, a grazing restrictor (10) is configured for attaching to a halter (34). The restrictor (10) comprises a body portion (13) having a central opening (16) sized to provide a throughput restriction on the amount of forage ingested while grazing. A plurality of elongate segments (19a-h) extend outward from the body portion (13). The aspect includes means for attaching the restrictor (10) to the halter (34). And the plurality of elongate segments (19a-19h) are configured and arranged such that, when the restrictor (10) is attached to the halter (34), the elongate segments (19a-h) are biased outwardly from the halter (34).
In another aspect of the invention, a combination 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 (19a-19h) extend outward from the body portion (13). The plurality of elongate segments (19a-19h) have a plurality of openings (25) defined therein. The plurality of elongate segments (19a-19h) 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 (19a-19h) 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.
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
A plurality of openings 25 may be disposed in the segments 19a-19h. The openings 25 on each segment 19a-19h 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
Turning to
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 19a-19h extend outward from the body portion 13. The plurality of elongate segments 19a-19h have a plurality of openings 25 defined therein. The plurality of elongate segments 19a-19h 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 19a-19h 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 19a-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.
The present invention contemplates that many changes and modifications may be made. Therefore, while the presently-preferred form of the grazing restrictor has been shown and described, and several modifications and alternatives discussed, persons skilled in this art will readily appreciate that various additional changes and modifications may be made without departing from the spirit of the invention.
