PET FOOD PROTECTING DEVICE

ABSTRACT

An apparatus is provided for protecting the food of a house pet and is particularly useful when a pet is fed outdoors. The pet feeding device covers the food intended for a pet and protects the food from birds and undesirable pests. The pet feeding device employs a tray having a hinged lid and a treadle upon which the pet steps to open the lid. the treadle is connected to a pair of parallel arcuate ram arms which are carried rearwardly when the pet steps on the treadle. The arms travel between guide rollers and push upwardly against the underside of the lid to raise the lid to an open position when the treadle is depressed. When the pet is finished eating it releases the treadle, whereupon a spring aids in shutting the lid.

~PE~I~IC~IQ~ I

The present invention is directed to a pet feeding and food protecting apparatus which is operated by an animal to be fed~

~omestic house pets form a part of many households not only in this country, but throughout the world. A conscientious owner of a pet will take considerable care to ensure that the pet is adequately fed and watered. Very typically, the owner of a pet, such as a dog or cat, will place food and water bowls on the floor or ground where they are readily accessible ~o the pet. The pet may not always want to eat and drink the entire conte~ts of the food and water bowls immediately, and often will return to them ~o nibble and :

13138~1 take wates from time to time.
It is frequently desirable to provide a pet with food and water out of doors. In many instances an owner may have to leave the pet for a number of hours. When a pet is left outdoors it has the opportunity to exercise.
Also, an owner will frequently leave a pet out of doors so that the pet will not defecate within a dwelling.
When a pet is left outdoors for an extended period of time, humane treatment requires that the pet be provided with food and water. ~owever~ when food and water bowls are left ou~ of doors uncovered, the readily available food and water attracts birds, rodents and other undesirable pests. These unwelcome ~cavengers ~requently spread food about the yard, porch or sidewalk in the vicinity of the location of the food and water bowls. As a result 7 pet ~ood becomes spread over the yard and sidewalk and the area becomes littered as well with bird and other pest droppings. Furthermore9 when the food and water intended for a pet are left uncovered, flies and insects often get into the pet's food.
To attempt to solve this problem various devices ~3~3801 have been developed for covering or protecting the food and water of an animal to be cared for. Typically such food protecting devices employ a treadle or some other means by which an intelligent animal, such as a house S pet, can li~t a cover from atop a food container.
However, the prior devices of this type w~ich have been developed are often constructed in such a way that the lid or cover is pushed up into the ~ace of the animal to be fed when i~ is opened. Pets become startled by such operating mechanisms and often develop an aversion to them. Also, the lid or cover of such conventional devices is frequently not opened sufficie~tly to effectively allow the pet access to the food and water which is covered when the pet feeding deYice is not in use.

A primary object of the present invention is to provide an animal feeding device which ope~ates smoothly and efficiently, in response to actions of the animal to ~20 be fed, so as to uncover the food of the animal in a 13~801 manner that avoids interfering with the animal's normal approach to the feeding bowls contained therein. The pet feeding appara~us of the invention is provided with a coYer which is hinged at the lower rear portion o~ a feeding tray. When the pet approaches the feeding tray, it will necessarily place its paws upon a~ actuating treadle located in ~ront of the tray in order to get close enough to the tray to eat the food which is located therewithin. The treadle is hinged along one edg~ at a treadle axis located remotely from the cover hinge axi~. The ~readle is connected at its opposite end to a ram mechanism. Once the pet depresses the treadle the ram mechanism is carried upwardly ~o push against the underside of the cover, thereby rotating the cover clearly and completely out of the way. The pet is therefo~e not startled by a cover op~ning into its face and does not have to struggle in order to eat through only a partial opening. To the contrary, the ram mechanism of the pet feeding device carries the 2~ cover rearwardly, well clear of the animal's face. ThP
unique shape of the ram head work~ like a cam thus causing the lid to open slowly at first and then ~3~3~

gain speed only after it is well clear of the ani~al's face. The pet can thus eat happlly and without distraction.
When the pet leaves the feeding apparatus, on the other hand, the release of pressure ro~l the treadle allows a resiliently deflected spring ,nechanism to return the cover to a closed position atop the feeding tray. Because the closing cover forces the ram mechanism forward the ram mechanism rnust lift the treadle. The weight of the treadle thereby ensures that the cover closes smoothly without slamming shut. The closed cover thereby prevents scavengers, such as birds and rodents, from gaining access to food located within the feeding device.
In one broad aspect the present invention is a pet feedin~ apparatus comprising a food tray having a front and a rear, a tray cover hinged to the rear of the tray, a foot plate hinged at a horizontal axis forward of the tray for rotation between an upwardly and rearwardly inclined released disposition and an actuated disposition depressed downwardly from the release disposition. A ram mechanism is provided having a first --S--~3~3~0~

end oriented to bear against the underside of the tray cover and a second end. Connection rlleans couple the second end of the ram Mechanism to the foot piate and guide means on the food tray engage with the ram mechanism to constrain the ram mechanism to move ia -ccncave upwardly facing arcuately curved path.
Depression of the foot plate to an actuated disposltion carries the rar,l upwardly to li~t the cover in ro~ation above the tray. Release of the foot plate allows ~he o cover to drop in counter-rotation onto the tray, there~y returning the foot plate to the released dlsposition~
The ram mechanism forms a very critical part of the invention. While the ram mechanism may take various forms, it preferably is comprised of a pair of ram arms on opposite sides o~ the food tray. Each of the ram arms is configured with upper and lower edges formed in circular arcs of different radii centered about a coinmon point. The food tray is comprised of opposing parallel sides extending between the transverse tray front and tray rear. The guide means are preferably comprised of a plurality of rollers rotata~ly mounted on each of the opposing sides of the food tray to bear against both the 1313gll~

upper and lower edges of the ram arms. In the pee~erred en~bodiment two rollers support the lower edge of each of the ram arms and a third roller rides against the upper ed~e of each of the ram arr,ls on the opposi~ sides o~
the food tray. The connection Means which joins the second ends of the ram arms to the foot pl~te is comprised of a pair of connection links hingedly coupled to the ram arms and to the foot plate.
The tray cover is hinged to the tray by means of 1~ a pair of coaxial cover hinge pins mounted on the opposing sides of the food tray. Preferably each cover hinye pin is keyed to rotate with the cover and carrie~
a leaf spring which bears against and is r~siliently aefl~c~ed by the rear of the tray whell the cover is lifted in rotation above the tray. The resilient deflection of the leaf spriny bi~ses ~he tray toward a closed position. The cover is hin~ed near the bottom at the rear of the tray, so that when the cover is raised ~y the ram arms, it is carried upwardly and rearwardly with a visor-like r,loven~ent. Depression of the foot plate by the animal to be fed therefore does not thrust the cover directly upwardly toward the animal's face.

~L313~

To the contrary, the cover is pushed upwardly and rea~wardly away fror,l the animal's face and to a position allowing the animal ~nobstr~cted access to the enclosure of the foot container.

Fig. 1 illustrates a device 10, which Inay be considered to be both an animal feeding device and a ~et food protecting device. The animal feeding devic~ 10 is cor,l~rised of a hollow g~nerally rectangular box-shaped food tray or container 12 having a front wall indicated at 14, a rear wall indicated at 16, and outsi~e side walls 22 that extend p~rpenaicular to tne fron~ wall 14 ~nd the rear wall 15 as best illustrated in Fiy~. 2, 5 and 6. A visor-like lid or cover 18 is hi.n~ed ~o the reâr of the food tray 12 near the lower rear extremity ; of the outside side walls 22 by ~lleans of cover hinge ~ins 20. The cover hinge pins 20 are coaxially ali4ned and extend inwardly through the opposite outer side walls 22. The lid 18 rotates about a hori~ontal lid axis defined by the cover hin~e pins 20 between a lifted ~3~3801 open position as depicted in Fig. 6, and a lowered closed position as depicted in Fig. 50 A leaf spring 24, depicted in detail in Fig. 3" is employed to bias the lid 18 toward the lowered, c;Losed posi~ion of Fig. 5 in a manner hereinafter to be de~scribed.
A foot plate or treadle 26 formed as a flat, rectangular slab is located in ront of the food tray 12 and is hinged at a hori~ontal treadle axis defined by treadle hinge pins 28. The treadle axis defined by the treadle hinge pins 28 is spaced forwardly from the front wall 14 of the ~ood tray 12. The treadle 26 is rotatable between a raised position inclined upwardly from the treadle axis toward the front wall 14 o~ the food tray 12~ a~ depicted in Figs. 1 and S, and a lowered position depicted in Fig. 6.
A very important feature of the invention is the ram mechanism which is comprised of arcuately, upwardly curved concave ram arms 30. Each of the ram arms 30 has ~.
a rear end portion 32 which bears against the underside ~ 34 of the lid 18 and a forward end portion 36 which projects forwardly beyond the front 14 of the food tray 12. Each of the parallel ram arms 30 also has an ~ 3~3~0~L

intermediate portion 38 of uniform width between the rear end portion 32 and the forward end poftion 36.
G~ide means in the form o a plurality of rollers 40, 42 and 44 are provided on both sides of ~he food tray 12 for guiding the ram arms 30 to move in circular, arculate fore and at paths. The forward ~nd portions 36 of the ram arms 30 pass through elongated vertical slots in the front wall 14 proximate to the side walls 22.
1~ Connection means in the form of a pair of flat oblong connecting links 46 are provided to join the forward portions 36 of the r m arms 30 ~o the treadle 26 remote from the treadle hinge pins 28. Depression of the treadle 26 to i~s lowere~ position pushes the ram . 15 arms 30 upwardly to lift ~he lid 18 to its open position, as depicted in Fig. 6.
The lid 18, the food tray 12, the ~am arms 30 and the treadle 26 are all preferably compfised of transparent, lucite plastic. Since the lid 18 is : 20 transparent, an animal is able to see food and water in the bowls 48 and 59 which are positioned atop a platform 86 within ~he enclosure of the food tray 12~ The bowls 1313~

48 and 50 are removable for purposes of cleaning and are omitted Erom Fig. 2.
A narrow, bead-like beari.ng ledge ~2 is formed of a plastic lucite molding and is ~ecured by glue to the pair of opposing, parallel generally rect~ngular-shaped fore and aft side walls 22 which form the outer exposed sides of the food tray 12 and extend between the feont 14 and the rear 16 the~eof. T~le lower edge 56 of the lid 18 rests upon the bearing ledge 52 when the lid 18 is closed. The bearing ledge 52 al80 serves the purpose of preventing the animal from lifting the lid 18 other than by depressing the ~readle 26.
Within the foad tray 12 and pro~im~te ~o each of ; the outer sidewalls 22 there is a vertically oriented L5 interior partition 58. Each of the partitions 58 is uniformly spaced from and located parallel to the proximately disposed outer side wall 22 to form a gap 62 therebetween, a~ best depicted in Figs. 1 and 30 The interior partitions 58 are secured by glue ~o the front wall 14 and the back wall 16 and are spaced approximately Eive sixteenths of an inch from the outer side wall 22 located proximate thereto. The cover hinge _____~__ ~313~1 pins 20 have ~hanks 60 which extend through transversely aligned openings in the closely spaced outer walls 22 and the interior partitions 58 and span th~ five sixteenths inch gap 62 indicated in Fig~ 3~ Within the enclosure o the animal eeding device 10 the cover hinge pins 20 are secured by C-rings 64 which snap into retaining grooves in the outer peripheries of the hinge pin shanks 60 in the manner depieted in Fig. 3. As illustra~ed in Fig. 3, the undersides of the headq of lo the cover hinge pins 20 are formed with he~agonal keys 66 which seat in corresponding hexagonal openings in the side walls 68 of the lid 18. Thus, as the lid 18 is rotated between its open position of Fig, 6 and its closed position of Fig. 5, the cover hinge pins 20 are carried in rota ion since they are keyed to the lid 1~
by means of the hexagonal keys 66 that are seated in the side walls 68 of the lid 18. The shanks 60 of the cover hinge pins 20 pass through circular openings in the outer sidewalls ~2 and in the inner partitions 58 and are thereby engaged in each of the opposing sides of the food tr y 12.
Each o the shanks 60 of the cover hinge pins 20 :L31380~

is provided with a longitudinal slot therethrough adapted to receive an elongated Igenerally rectangula~
leaf spring 24. One end of each leaf spring 24 is inserted into the slot in a shank 60. The end of the leaf spring 24 which is inserted into the 810t iS
inelastically deform~d to a slight degree with ripple-like bends so that the leaf spring 24 will not fall out of the slot in ~he hinge pin shank 60. The other end of the leaf spring 24 extend~ upwardly. As the lid 18 is opened, as depicted in Figs. 2 and 6, the leaf springs 24 are rotated with the cover hinge pin ~0 and are carried into contact with the rear wall 16 of the food ~ray 12. As illustrated in Fig. 2, the leaf springs 24 are resiliently deflected by the rear wall 16 so as to urge the lid 18 to re~urn toward its lowered~
clos~d position.
The guide rollers 40, 42 and 44 are all identical in configuration and are likewise secured in the gaps 62 between the outer food tray walls 22 and the adjacent interior partitions 58g in the manner depicted in ~ig. 4. Each of the rollers 40, 42 and 44 is a disk-like generally spool-shaped structure and rotates ~313~01 on the shank of a roller mounting pin 70. The rollers 40 and 42 support the rounded, lower edges 72 of the ram arms 30, while the rollers 44 bear against the correspondingly curved upper edges 74 o~ the ram arms 30. The rollers 40, 42 and 44 al;L support and guide the ra~ arms 30 and bear against the intermediate portions 38 thereof.
Since the intermediate portions 38 of the ram arms 30 are o~ uniform width~ the ~ollers 40 and 42 will always remain in contact with the lower edges 72 o~ the intermediate ram arm por~ions 38 while the rollers 44 will always remain in contact with the upper edges 74 of the ram arms 30. The rollers 40 and 42 are located below the curved ram arms 30, while the rollers 44 are located thereabove. The intermediate portions 38 of the ram arms 30 are support~d from beneath by the rollers 40 and 42 and are constained ~rom above by the rollers 44 when the treadle 26 is moved between its raised and lowered positions~
The treadle 26 is connected by treadle hinge pins 28 to a stationary~ flat, rectangular lucite base pla~e 76 located therebenea~h. The stationary ba~e 1313~1 plate 76 is horizontally disposecl beneath ~he treadle 26 and has a pair of upstanding vertical ears 78 arranged in lateral alignment with each other. The treadle hinge pins 28 project through the ear~ 78 in coa~ial alignment with each other and into the structure of ~he treadle 26 at one end thereof. The treadle hinge pins 28 thereby hingedly join the treadle 26 to the base plate 76.
The opposite end o the base plate 76 is turned upwardly in a lip U0 which is located behind an opening 82 beneath the front wall 14 of ~he food tray 1~, as best illustrated in Fig. 2. To assemble the animal feeding device 10, the base plate 76 is positioned flat on a supporting surface, and the food tray 12 is lowered so that the upstanding lip 80 is disposed within the enclosure of the food tray 12 and resides in abutment against the interior surface o~ the front wall 14 in the manner depicted in Fig. 2. Once the base plate 76 is in position, the connecting links 46 are secured to both the second or forward ends 36 of the ram arms 30 and to the structure of the treadle 26 remote from the hinge pins 28 by means of fastening pins 84.
To utilize ~he animal feeding device 10 a user ~313~01 assembles the component part~ together in the manner depicted in the drawing figures and positions the food and water bowl~ 48 and 50 on the elevated, horizon~al platform 86 that is located betw~en the front and rear wall~ 14 and 16, respectively~ and the interior partitions 58. The plat~orm 18 is removable for cleaning, A central, fore and aft brace 88 is located beneath the horizontal partition ~6 and provides support thereto. The brace 88 also serves to stablize the fr~nt and rear walls 14 and 16 and to hold those walls parallel to e~ch other.
With food and water in the bowls 48 and 50 a pet may approach the pet feeding device 10 at any tim~
Because tbe lid 18 i transparen~ the pet is able to readily observe any food and water in ~he bowls ~8 and SO .
As the pet approach~s the food protec~ing device 10, the animal will necessarily place one or both of its front paws on the treadle 26, thsreby depressing the ~20 treadle from its normal, upwardly and rearwardly inclined deactuated position, depicted in FigsO 1 and 5, to an actuated position depressed downwardly in rotatio~

~313~0~

from the deactuated position, as depict~d in Figs. 2 and 6. As the treadle 26 is depressed, the guide rollers 40, 42 and 44 contact the edges 72 and 74 ~f the ram arms 30 to constrain the ram arms 30 ~o move in arcuate path6 within the gap8 62 between the ou~er sidewalls 22 and the ~ore and aft interior p~rtitions 58 located adjacent thereto. As the treadle 26 is depressed, the ram arms 30 move away from the treadle axis defined by the treadle hinge pins 28 and the rear ends 32 of the ram arms 30 are driven upwardly and to pus~ the lid 18 open in counterclockwise rotation, as viewed in Figs. 2, 5 and 6. The movement of the ram arms 30 in their arcuate paths pushes the lid 18 from the lowered, closed position depicted in Fig. 5 into its raised, opened position depicted in Fig. 6. When the lid 18 is raised in this manner the pet to be fed will stand wi~h its forepaws pressing downwardly on the treadle 26. Th~ pet can then readily eat and drink from food and water bowls 48 and 50. When the lid 18 is in the raised position o~
Fig. 6 the contents of the food tray or containel 12 are :~ fully exposed ~o allow ~he pet unrestricted access thereto.

:

~311 3~01 When the pet has fini~hecl eating and drinking, it will leave the device 10, removing its paws from the treadle 26. Since the lid 18 was raised t~ its elevated, lifted position of Fig~, 6, the spring 24 is resiliently deformed, and is deflected against the interior surf~ce of the rear wal]L 16~ as depicted in Fig. 2. The eear portion o~ the ~ar partition 58 i6 broken away in Fig. 2 to facilitate observation of the deflected &pring 260 Relea~e of the treadle 26 allows the spring 24 to push against the rear wall 16 and rotate the cover hinge pins 20 in a clockwise dir~c~ion, as viewed in Figs. 2 and 6. Since the cover hinge pins 20 are keyed to the lid 18, the lid 18 is likewise turned in clockwise rotation as well. When the center of gravity of the lid 18 passes to the right of vertical alignment with the cover hinge pins 20, the force of gravity will also cause the lid 18 to drop in~o a fully closed position with i~s lower edge 56 resting upon the : bearing ledge 52, as depicted in Figs. 1 and 5~ The closing of the lid 18 will be slowed somewhat by the resi~tance encountered as a result of raising ~he treadle 26. This tends to keep the lid ~rom slamming 13~38~

shut. The pet feeding device 10 thereupon protects the pet's food and water in the bowls 48 and 50 from birds and other pests. I
Undoubtedly, numerous variations and modifications of the invention will become readily apparent to those familiar with pet feeding accessories.
Accordingly, the scope of the invention should not be construed as limited to the specific embodiments illustrated and described herein, but ra~her is de~ined lo in the claims appended hereto.
