1. Field of Invention
This invention relates to animal feeders, particularly to a device and system for a feeding system that is accessible to one smaller animal, but is exclusionary to another larger animal. In addition, the present invention may be composed of three main interlocking elements; one being a food container that allows a caregiver to place enough food to feed the smaller animal for multiple days, thereby easing the amount of effort needed to feed the smaller animal, another being a housing chamber that is equipped with a size-exclusionary opening, and the third component being a base unit that can receive the feeding container and housing chamber, if desired.
2. Brief Description of the Prior Art
Many animal feeders have attempted to address a multitude of issues that may arise. For instance, multiple patents have been issued for devices that alleviate the caregiver's need to fill a container with food for the animal on a daily basis (See U.S. Pat. Nos. 6,401,657, 4,248,175, and 3,763,826). Other prior art recites devices that preclude other animals from entering the eating domain of one animal (See U.S. Pat. Nos. 7,458,336 and 4,793,290 and U.S. Patent Application No. 2006/0272584). The advent of small devices powered by radio frequencies to gain entry into a space, as described in U.S. Pat. No. 7,458,336, allows caregivers a high-tech and high-expense option when trying to separate different types of animals during the feeding process.
Presently, no animal feeder exists that is self-sustaining, portable, size-exclusionary and inexpensive. There is a need for animal feeders that are cost-effective, easy to use, and allow caregivers to feed one animal in a secluded environment. The present invention addresses these needs. As will be seen from the subsequent description, the preferred embodiment of the present invention overcomes these and other shortcomings of the prior art.
Homes with multiple pets often have difficulty controlling feeding behavior of the individual pets. This is especially apparent where different animals have various dietary needs and/or preferences for their eating environment. For example, in homes where both cats and dogs reside, dogs are notorious for interfering with the cat's food and feeding environment. Meanwhile, it is not common for a cat to interfere with a dog's food. Many caregivers with both dogs and cats resort to feeding the animals in separate physical locations (rooms, counters, etc,) and at separate times, at much effort to the caregiver. A device that restricts access of larger animals to a smaller animal's food, and allows the caregiver to put enough food in the feeding system to supply the smaller animal with food, for a multitude of days if desired, would be advantageous. Such a device is not currently available.
The present invention is an animal feeder that allows for continued feeding, over a multitude of days if desired, of a smaller animal and has the ability to exclude other larger animals from its interior. The animal feeder may be constructed from three separate parts and excludes other animals by way of a size-exclusionary opening. Alternatively, the feeder may be made as one contiguous piece. The feeder may be constructed of plastics, polymers, fiberglass, epoxies, resins, polycarbonates, molding compounds, glues, woods, metals and the like.
Consequently, the animal feeder may be made up of three main interlocking parts. The first is at least one base member that sits on a floor or surface and receives the food container and may receive the housing chamber, if desired. Latches may be used to secure the base to the other main parts of the present invention. The second is a container that is adaptable for holding food, and may hold enough food to feed the smaller animal for many days. The container has at least one opening to release food to the animal and may have an upper door used to deposit the food therein. The food-loading door may be coupled to a spring or locking mechanism to prevent animal entry into the container. The feeding chamber may allow the animal access to food through gravity flow, which may be effectuated by a slope in the bottom portion of the food container, or alternatively, integrated into the base as an upper surface. Egress of food may be slowed by the presence of a flap in the opening that releases food to the animal. The third part is a housing chamber that connects to the base, forming an enclosure in which the animal is able to reside while feeding. This housing chamber contains an opening that allows the smaller animal entry to its food and prevents a larger animal from entering. An entry door that is large enough for the smaller animal to gain access to its food, but is too small to permit the entry of another larger animal, can cover the opening in the housing chamber. For example, the housing allows the entry of a house cat, but not a medium-sized domestic dog (i.e., Labrador retriever, German Shepard, Collie, etc.). The feeding container and housing chamber are adaptable to be received by the base member (or base members) to form one unit. Alternatively, the housing chamber will function adequately with no base member, while the food container does have a base member. Additionally, a food-retaining bowl may be added to the base, so that as the food flows out of the food container it fills the bowl, and prevents food from spilling into the remaining interior of the housing chamber. Still other modifications and positions of these elements may be implemented, as will be apparent to one skilled in the art.
The present invention is very affordable and easy to use in comparison with newer exclusionary feeding systems that require special collars for the animal and the door to operate and reserves enough food to feed the animal for many days. The animal feeder of the present invention may be made of inexpensive, durable, and easy to maintain materials. The animal feeder may be fabricated in a variety of sizes and shapes to accommodate caregivers with different types of animals of different sizes. Additionally, the present invention provides a simple device that works without the use of mechanical or electrical parts, which are susceptible to breakage and expense. Moreover, the fabrication of the present invention is such that the feeder is portable and may easily be transported within the home, or to other areas where the animals may be.
Positioning of the three main elements of the animal feeder of the present invention may be altered for customized use. For example, as stated above, the animal feeder functions properly with no base underneath the housing chamber. Furthermore, additional elements may be added. For example, a cover may be fabricated and placed over the housing chamber to reduce light in the housing chamber as is preferred by some animals. Such a cover also assists in creating a secluded environment that may be perceived as safer and comfortable for the feeding animal. Such a cover will also prevent larger animals from observing the feeding chamber and reduce the likelihood that they will disturb the feeding animal. Additionally, an extra chamber may be attached to the housing chamber so that an excluded animal is less likely to disturb the interior of the housing chamber, thus providing additional security and privacy to the feeding animal.
One object of the present invention is to provide a cost effective, portable, and non-technical means for a caregiver with multiple animals to provide a smaller animal an area to feed without interference from a larger animal, for a multitude of days if desired.
It is a further object of the present invention to provide an inviting area for a smaller animal to enter and eat without interference from a larger animal.
It is a further object of the present invention to provide an animal feeder that allows a caregiver to deposit food that will feed the smaller animal for a multitude of days without need to replenish the food supply by the caregiver.
It is a further objective of the present invention to provide an animal feeder that will contain food spills created by the animal, preventing such spills from spreading into the household.
It is a further objective of the present invention to provide an animal feeder that can be easily cleaned by the caregiver.
It is a further objective of the present invention to provide an animal feeder that may be used within a home and be able to be transported with ease.
Still other aspects of the present invention will become apparent to those skilled in the art from the following description of a preferred embodiment, which is by way of illustration, one of the best modes contemplated for carrying out the invention. As will be realized, the invention is capable of other different and obvious aspects, all without departing from the invention. Accordingly, the drawings and descriptions are illustrative in nature and not restrictive.

The size-excluding opening 106 may be of various sizes appropriate to exclude the unwanted animal, but allow entry by the animal that is to eat the food therein. For example, in one preferred embodiment of the invention the opening is equipped with a size-excluding door 106 that is approximately 7 inches in height, and 6 inches in length. But, the invention can function properly, as is apparent to one skilled in the art, with no door, and only a size-excluding opening. A size-excluding door 106 may cover the opening, as in one embodiment of the invention, and may be affixed to the housing chamber 101 in a variety of ways, as will be apparent to one skilled in the art. In one preferred embodiment, the size-excluding door 106, is affixed to the feeding chamber 101 at the topmost section in a manner that allows the door 106 to move freely into the housing chamber 101 when pressed by the animal, and out of the feeding chamber 101 as the animal exits the feeding chamber. Moreover, while
The housing chamber 101 is shown in rectangular shape in
As shown in
The food container 108 has an opening in the top wall 109 equipped with a food-loading door 114, for the caregiver to deposit food therein. The food-loading door 114 may be spring loaded or include a securing latch to keep the door 114 in the closed position, so as to further prevent tampering with the food contained therein by animals, as in one preferred embodiment of the present invention. The food container 108 will also contain an opening 115 at the bottom to allow for the food in the food container 108 to flow into the food-retaining bowl 118. The food-retaining bowl 118 may be attached to the front wall 112 of the food container 108, or be affixed to the base member 117 as in the preferred embodiment of the present invention.
Additionally, the bottom of the food container 108 may be slanted 116 to provide a gravity-flow mechanism for the food to flow out of the opening 115 and into the food-retaining bowl 118. Alternatively, the slanted floor 116 may be part of the base member 117, as in the preferred embodiment of the present invention. As in the preferred embodiment, the food container 108 is approximately 12 inches in height, 13 inches in length, and 6 inches in width. The food-loading door 114 is approximately 10 inches in length, and 4 inches in width. In this embodiment, the food container 108 is able to hold approximately 20 pounds of domestic cat food.
Other dimensions and shapes for the food container 108 are contemplated, and do not depart from the scope of the present invention. As stated above, the food container 108 may be constructed from a variety of materials. In one preferred embodiment, the food container 108 is made of IRIS, USA plastic because it is easy to clean, translucent for monitoring food quantities, durable, and lightweight.
As is apparent to one skilled in the art, the food-loading door 114 may be affixed to the food container 108 by a variety of means, including a hinged or flap mechanism that may be coupled with a latch to prevent entry by other animals. Additionally, a simple tongue-and-groove mechanism between the top wall 109 of the food container and the food-loading door 114 will accomplish the same goal (i.e. providing means for the caregiver to load the food container 108 with food and seal the food container to prevent entry by an animal). As is apparent to one skilled in the art other shapes and sizes for the food-loading door 114 may be implemented without departing from the scope of the invention. As in the preferred embodiment, the food-loading door 114 is approximately 10 inches in length, and 4 inches in width.
As in the preferred embodiment, the slanted floor 116 is angled at about 30 degrees, and the opening 115 to the food-retaining bowl 118 is approximately 3 inches in height, and 6 inches in length. As is apparent to one skilled in the art, any fabrication that moves food down into the food-retaining bowl 118 through the opening 115 by gravity may be contemplated without departing from the scope of the present invention. The slanted floor 116 may be affixed to the side walls 110, 111, 112, and 113 of the food container 108 by a variety of means that are well known in the art. As in the preferred embodiment of the present invention, the slanted floor 116 is generally constructed of the same material as the food container 108 or base 117, IRIS, USA plastic.

Alternatively, the base member 117 may be comprised of two separate pieces 119 and 120 as illustrated in
In addition to the description above, as illustrated in
Moreover, an extra chamber 128 may be fitted to the housing chamber 101, as illustrated in
The length of the left side panel 131 and right side panel 132 are such that a larger excluded animal cannot put its head, or other body part, through the extra chamber door 130 and reach the inner housing chamber 101 size-excluding door 106. In one preferred embodiment of the invention, the height of the extra chamber 128 is the same as that of the housing chamber 101 plus the base, approximately 16 inches. In this preferred embodiment, the length of the extra chamber 128 is approximately 8 inches. The opening with a door 130 of the extra chamber 128 approximates the measurements of the size-excluding door 106 of the housing chamber 101. In a preferred embodiment, the opening and door 130 is approximately 7 inches in height, and 6 inches in length. The door 130 of the extra chamber 128, like the size-excluding door 106 of the housing chamber 101 is attached at its topmost side. The door 130 retains the ability to swing inward to the housing chamber 101 when pressure is applied, and swing outward when the feeding animal exits the extra chamber 128.
Many means of attaching the door 130 to the extra chamber 128 are contemplated, and are similar to those means described above for the size-excluding door 106 and its attachment to the housing chamber 101. In one preferred embodiment the door 130 is affixed to the extra chamber 128 by mechanism that allows the door to swing freely into and out of the chamber. Moreover, the extra chamber 128 may be fabricated with a variety of materials such as plastics, polymers, epoxies, natural and synthetic fibers, metals, or woods. In one preferred embodiment the extra chamber 128 is made of IRIS, USA plastic. This preferred embodiment allows for easy cleaning, is lightweight, and durable.
