Abstract
Abstract An adjustable animal feeder includes a support base, at least two arms, a vertically adjustable support plate having an opening for detachably receiving a dish and locking elements for holding the support plate in a selected position. Because the support plate can be positioned and locked at a selected height, the animal which is to feed or drink from the dish held in the opening of the support plate can be accommodated. Posture of and digestion for the animal can therefore be improved. The feeder also includes tracks beneath the support plate for receiving only the dish, only a closure element or both the dish and the closure element for storage thereon. The support base of the feeder can act as a storage compartment or can be designed to fold to a position requiring minimal space. Further, the arms can be integral with or detachable from the base and can have grooves or pegs thereon for accommodating the support plate. The arms may alternatively be designed as a lazy tongs linkage which will be arranged to move the support plate and dish toward the front of the feeder as the support plate is raised. The arms may also be designed with guideways therealong to guide the support plate in vertical adjustment and with locks to hold the support plate in position.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
221 words
An adjustable animal feeder comprising: a support base having a front and rear side; at least two arms extending upwardly from said base, each of said at least two arms having guideways along the length thereof; a vertically adjustable support plate operatively connected to each of said at least two arms, said support plate having a generally flat top surface with an opening defined therein; means on said support plate for interengaging with said guideways whereby said support plate can be moved along the length of said at least two arms to a selected vertical position; a dish detachably insertable into said opening in said support plate for receiving one of food and water therein; means for locking said support plate at the selected vertical position, said vertical position being selected to accommodate height of an animal which is to feed or drink from said dish, said means for locking being operatively connected to said means for interengaging; and a compartment on the rear side of the support base, said support plate extending between said at least two arms and projecting toward the front side of the support base, said compartment acting as a counterbalance to downward forces applied to the support plate whereby said support base with the compartment prevents the feeder from tipping over when an animal feeds therefrom.
Claim 2
Dependent Claim
221 words
An adjustable animal feeder comprising: a support base having a front and rear side; at least two arms extending upwardly from said base, each of said at least two arms having guideways along the length thereof; a vertically adjustable support plate operatively connected to each of said at least two arms, said support plate having a generally flat top surface with an opening defined therein; means on said support plate for interengaging with said guideways whereby said support plate can be moved along the length of said at least two arms to a selected vertical position; a dish detachably insertable into said opening in said support plate for receiving one of food and water therein; means for locking said support plate at the selected vertical position, said vertical position being selected to accommodate height of an animal which is to feed or drink from said dish, said means for locking being operatively connected to said means for interengaging; and a compartment on the rear side of the support base, said support plate extending between said at least two arms and projecting toward the front side of the support base, said compartment acting as a counterbalance to downward forces applied to the support plate whereby said support base with the compartment prevents the feeder from tipping over when an animal feeds therefrom.
Claim 3
Dependent Claim
44 words
The adjustable animal feeder as recited in claim 1, further comprising track means for selectively receiving at least said dish for storage beneath said support plate, said track means being mounted on an underside of said support plate and being proximate to said opening.
Claim 4
Dependent Claim
44 words
The adjustable animal feeder as recited in claim 1, wherein each of said arms have a plurality of longitudinally spaced openings within said guideways, said openings receiving a portion of said means for locking to hold said support plate in said selected vertical position.
Claim 5
Dependent Claim
84 words
The adjustable animal feeder as recited in claim 3, wherein said means for locking comprises a movable, spring biased detent, said portion of said means for locking comprising an end of said detent which is slidable into and out of said spaced openings, said means for locking being movable along the length of the arms with the support plate and said portion being slid into a selected opening to lock said support plate in position when said plate is at said selected vertical position.
