[0105] The exploded views of FIGS. 1 and 2 provide an overview of the basic components of an embodiment of a food dispenser 1 seen from different angles.

[0106] All main components will be discussed in further details in relation to additional figures of each component, in relation to figures illustrating the food dispenser in assembled state, as well as by way of sections taken through the food dispenser 1 in its assembled state.

[0107] The main components of the food dispenser 1 are a base plate 2, a feeding bowl 3, a first lid part 4, a second lid part 5, a synchronization ring 6 for operative interaction with the feeding bowl 3 and the base plate 2 as part of a rotary mechanism, an elongated actuator 7 that is in operative engagement with the second lid part 5, a cover part 8 for covering a receptacle (not visible), which receptacle has its opening at a bottom face 16 of the base plate 2. The receptacle accommodates at least the electronic means 10 and a motor unit (not shown). The cover part 8 has a battery compartment 11 for batteries 12. The battery compartment 11 is operated from outside the food dispenser 1 and has a closure lid 13 designed with cavities 18 for holding the batteries 12 when the battery compartment 11 is closed. A first sealing ring 9 is inserted between the bottom face 16 and the cover part 8 to seal the food dispenser 1 and aid in protecting the components inside the receptacle from the environment. The cover part 8 is screwed together with the base plate 2 at the bottom face 16 using a suitable number of screws 19 inserted via a corresponding numbers of screw holes 20 in the cover part 8 to close the receptacle. The number of screws 19 and screw holes 20 can be any although only two are seen in FIG. 1. The cover part 8 provides a closed compartment for electric contacts to be activated by the actuator 7, electric on/off switches for turning on/off signaling means, such as a speaker or LED, or power switches, motor unit 111, microprocessor, transceivers of the wireless communication means, etc. as will be explained in more detail in the further figures. A second sealing ring 21, e.g. of water-proofed silicone, is provided between the closure lid 13 and the battery compartment 11 to ensure that humid or other matter does not unintentionally enters the battery compartment 11.

[0108] A switch cover 22 is to be mounted in a first hole 23 of a first socket 24 of cover part 8, so that an on/off switch (not shown) can be operated from outside the food dispenser 1 to switch on/off power. A plurality of feet 25, such as rubber ferrules, are distributed at the base face 16 of the base plate 2 to serve as anti-frictional means when the animal operates the food dispenser. Preferably the feet 25 are distributed circumferentially along the perimeter of the bottom face 16 of the base plate 2.

[0109] A coaxial antenna 26 and a transceiver (not shown) are provided to ensure wireless communication between several food dispensers 1 within wireless signal transmitting and signal receiving distance.

[0110] The elongated actuator 7 has an inner part 27 located through an O-ring 28, and a first spring 29 for spring-biased axial displacement. A recess or window opening 30 in the circumferential skirt 31 of the first lid part 4 serves for presenting a logo or sign 32, which logo pr sign 32 is protected by a window cover 33. The window cover 33 can e.g. be snapped-fit into the recess or window opening 30 to trap the logo or sign 32, or be glued or hot-welded together.

[0111] The main components are also seen in FIG. 2 and will be described in further detail with reference to individual figures.

[0112] FIG. 3 shows the base plate 2 in a perspective view oblique from above. The base plate 2 has an overall appearance of a tapering shell 17 in order to, on then one hand be able to fit inside the feeding bowl 3 and to serve for mounting the synchronization ring 6, and on the other hand be adapted for housing more or less of the rotary mechanism, the electronic components and the wireless communication means.

[0113] More specifically, the base plate 2 has a lower portion 34 extending via an intermediate portion 35 further into a top portion 36, which terminates into a central upright tubular connection piece 37 for passage of the inner part 27 of the actuator 7 to allow said inner part 27 to switch on/off contacts located in the receptacle. The lower part 34 of the base plate 2 is a support plate 38 with anti-sliding feet 25 on the base face 16. The lower part 34 includes support plate 38 with the base face 16 on one side, and on the opposite side the support plate 38 has a peripheral upright rim portion 39 that in assembled state of the food dispenser 1 surrounds the lower circumference of the feeding bowl 3. A circumferential waste groove or food collection groove 40 is delimited between an internal diameter 41 of the upright rim portion 39 and an external diameter 42 of a first tubular lower part 43 of the intermediate portion 35. The first tubular lower part 43 of the intermediate portion 35 extends into a first truncated cone part 44. The circumferential outer wall face 45 of the first truncated cone part 44 serves as an abutting sliding face for the feeding bowl 3 in assembled state of the food dispenser 1 during rotation of the feeding bowl 3. The upper surface 46 of the first truncated cone part 44 defines a plateau 47 on top of which the top portion 36 is located. The top portion 36 includes a second tubular part 48 having a smaller diameter than the plateau 47 to define a shoulder 49 on the plateau 47 for mounting an annular ring part 50 of the synchronization ring 6, which second tubular part 48 extends into a second truncated cone part 51 wherefrom the central upright connection piece 37 projects axially.

[0114] The outer annular part of the support plate 38 that includes the bottom of the waste groove or food collection groove 40 has annularly distributed first securing holes 52 allowing the food dispenser 1 to be anchored, e.g. using screws via the securing holes to some kind of base, such as the floor. If the first securing holes 52 are left free they advantageously also can serve as drainage holes. The upright rim portion 39 and/or waste groove or food collection groove 40 have through-holes 53 for easier mounting, detaching and/or replacing the feet 25, thus to be able to easily push the feet 25 out of the support plate 38. Second securing holes 54 in the shoulder 49 serves to fix a motor unit (not shown) inside the receptacle 55 seen better in the bottom view of FIG. 4 of the base plate 2. The shoulder 49 has a plate spring opening 55 for a protruding plate spring (not shown) that mechanically controls the angle the rotary mechanism can rotate the feeding bowl by its engagement with the synchronization ring 6, optionally upon input from a microprocessor and/or in response to switching on/off a contact upon depression of the plate spring e.g. when the animal activates the actuator. The protruding plate spring engages with stops on the synchronization ring 6, as will be seen in the below FIGS. 6 and 7 of the synchronization ring 6.

[0115] Further, the second tubular part 48 of the top portion 36 has a drive hole 56 that allows a second drive means (not shown) associated with the base plate 2 to protrude. The second drive means can e.g. be a first toothed gear wheel in transmission with another second toothed wheel on a motor shaft of a motor unit.

[0116] The base plate 2 has annularly distributed peripheral second engagement means 57 located in the upright rim portion 39 of the lower part 34 of the base plate 2. Optionally the peripheral second engagement means 57 extends into the waste collection groove 40 too, to expose a larger area for engaging peripheral first engagement means 58 along a free bottom edge 59 of the first lid part 4, as seen in FIG. 2. In the present embodiment the food dispenser 1 has seven female peripheral first engagement means 58 and seven male second peripheral engagement means 57 that lock the first lid part 4 to the base plate 2 by snap-coupling. In the present embodiment the female first peripheral engagement means 58 are substantially axially protruding webs with a hook that snaps together with second male peripheral engagement means 57 in form of holes.

[0117] The circumferential wall 60 of the tubular connection piece 37 has two opposite axially extending flexing leaf springs 61 with respective radial outwards facing noses 62 below which the synchronization ring 6 in held in position on the base plate 2, so that a first drive means of the synchronization ring 6, such as a toothed wheel or belt 63, is in operative driving contact with a second drive means, such as a gear wheel that protrudes from the drive hole 56 of the second tubular part 48 of the top portion 36 of the base plate 2 to rotate in the radial plane of the base plate 2.

[0118] FIG. 4 shows the base plate 2 from the bottom face 16 of the base plate 2. The circumferential shell 17 delimits a hollow interior divided by an interior cylindrical wall 63 into the receptacle 55 surrounded by a circumferential channel 64 that facilitates grasping of the food dispenser 1 by providing a suitable gripping cavity. The receptacle 55 houses a plurality of reinforcing ribs 65, spacers 66 for keeping distance to the cover part 8, and mounts 67, for e.g. a double sided printed circuit board (PCB) that mechanically supports and electrically connects the electronic components, including the microprocessor, the antenna, the transceiver, the control unit, the signaling means etc.

[0119] FIG. 5 is an axial sectional view taken along line V-V in FIG. 3 to illustrate the receptacle 55 inside the step-pyramidal shell 17. The tubular connection piece 37 is in open communication with the interior space 68 of the receptacle 55, and thus with components situated inside the receptacle 55.

[0120] FIG. 6 is a perspective view of the slightly tapering dish-shaped synchronization ring 6 seen oblique from above. The synchronization ring 6 has an annular ring part 50, delimiting a ring opening 69 for passage of the actuator 7. An exterior face 70 of the synchronization ring 6 constitutes an upper engagement face 70 provided with a third engagement means 71 in form of indents or cavities 71 adapted to interlock and/or engage fourth engagement means 72 in form of projections or steps 72 on the interior part 73 of a tapering main body 74 of the feeding bowl 3, as shown in the subsequent FIGS. 10 and 11.

[0121] As seen better in the top view of FIG. 8 the synchronization ring 6 has seven indents or cavities 71.

[0122] As seen better in the bottom views of FIGS. 7 and 9 the interior face 75 opposite the exterior face 70 is the lower drive face 75 provided with a first drive means 63, in the present case a toothed belt 63. The first drive means 63 are encircled by a ring of seven stops 76 for in turn snapping over a plate spring protruding axially upwards through the plate spring opening 55 of the base plate 2 each time the feeding bowl 3 is rotated 7/360 to dispense food from a respective food compartment 77 of the feeding bowl 3 shown in FIGS. 10 and 11.

[0123] Similarly to the base plate 2 and the synchronization ring 6 the feeding bowl 3 are tapered so that said components can be stacked in operative engagement with each other.

[0124] The feeding bowl 3 has a tapering main body 74, a feeding bowl base 78, and a central opening 79 in axial distance from the feeding bowl base 78, which central opening 79 allows passage of the inner part 27 of the actuator 7 with an enlarged actuator head protruding from the opening. The tapering main body 74 has an interior part 73 configured with fourth engagement means in form of projections 72 that engage the third engagement means 71 of the synchronization ring 6 for rotation. An exterior part 80 of the feeding bowl 3 is configured with seven angularly spaced-apart partition walls 81 for delimiting a plurality of seven, angularly, spaced-apart, inclined food compartments 77, configured as chutes 82 with guide grooves 83 diverging in fan-shape 84 from the central opening 79 towards the feeding bowl base 78.

[0125] FIG. 12 is a perspective view of the first lid part 4, and FIG. 13 shows the same in a perspective view from the bottom inside the first lid part 4.

[0126] The circumferential skirt 31 of the first lid part 4 has an outlet opening 85 for delivery of a food portion to the animal subsequent to actuation of the actuator 7. A food compartment is rotated in front of this outlet opening 85 and food slides by virtue of gravity on the chute 82 and out via the outlet opening 85 to be taken by the animal. Food is charged to the food compartment 77 of the feeding bowl 3 via a central charging opening 86 once the first lid part 4 is coupled to the base plate 2.

[0127] The elongated actuator 7 is seen in FIG. 15 aligned axially with the second lid part 5. The actuator 7 has an inner part 27 to be mounted in the tubular connection piece 37 of the base plate 2 so that a free manipulation end 87 with an actuator head 88 can engage a clamp 89 on the interior face 90 of the second lid part 5, a seen in FIG. 14, when said second lid part 5 is mounted to cover the central charging opening 86 of the first lid part 4. At the exterior face 91 of the second lid part 5 the clamp 89 for connecting the actuator head 88 to the second lid part 5 may have a transparent or light-penetrateable top cover 92 that allows light to pass through, e.g. an outwards curving transparent plastic cover. Optionally the entire second lid part 5 is transparent or light-pentrateable. Together the actuator head 88, the top cover 92 and the second lid part 5 constitute a combined button, which the animal pushes, presses on, or otherwise manipulates to activate a contact for the motor unit of the rotary mechanism and make this rotary mechanism to work to dispense a food portion. The radial skirt 93 surrounding the clamp 89 can move slightly up and down in relation to the first lid part 4, which may be sufficient for activation of the actuator 7 even though the actuator 7 itself is not hit. The large surface of the radial skirt 93 of the second lid part 5 provides an expedient long arm for force application to said actuator 7 that makes it easy for the animal to be successful to activate the food dispenser 1, and thus to dispense a food portion by rotating the feeding bowl 3. In the present embodiment the clamp 89 consists of a plurality of flexible fingers 94 arranged in a ring to fit and snap over the actuator head 88. The flexible fingers 94 are oriented radially around the top cover 92 to protrude axially therefrom.

[0128] The enlarged scale views of FIGS. 16 and 17 shows more specifically the structure of the actuator 7. The actuator head 88 extends via a first coupling flange 95 for coupling with the flexible fingers 94 of the clamp 89 of the second lid part 5 via a tubular piece into a second flange 96 having a larger diameter than the internal diameter of the tubular connection piece 37 of the base plate 2, so as to allow the second flange 96 to abut the free end of said tubular connection piece 37. The tubular connection piece 37 may have an internal thread (not shown) to couple with an external thread 97 of the inner part 27 of the actuator 7 below the second flange 96. Other means than threads may be used alternatively for coupling the actuator 7 firmly inside the tubular connection piece 37. The inner part 27 is in the present embodiment a hollow tubular part extending from the second flange 96 towards an actuator end 98 for activating electric contacts inside the receptacle 55 of the base plate 2. In the present embodiment the inner part 27 is, by means of slots 100, divided into four axially extending legs 99 to confer suitable radial flexibility to the inner part 27 that facilitates easy mounting inside the tubular connection piece 37. Each leg 99 has a radially protruding bead 101 that engages the inner wall of the tubular connection piece 37 and/or holds the spring 29 in axial position.

[0129] FIGS. 18 and 19 show an embodiment of the cover part 8. Emphasis is made that this specific design is only exemplary. The design and topography of the upper side 102 of the cover part 8 depends mainly on the arrangement of the components that are located inside the receptacle, and the design and topography of the lower side 103 depends on the number and choice of switches, batteries, microphones, etc, that shall be accessible from outside the food dispenser 1. Thus, any design of cover plate 8 suited to cover the receptacle 55 of the base plate 2 is within the scope of the present invention.

[0130] The first socket 24 has a first hole 23 on the upper side 102 for enabling a power supply contact located on a PCB (not shown) inside the receptacle 55 to be operated via an on/off power switch accessible from the lower side 103. Similarly, a second socket 104 has a second hole for making a contact for the signaling means located on a PCB (not shown) inside the receptacle 55 to be operated via an on/off switch (not shown) accessible from the lower side 103. A microphone 105 consists of a tube 106 that ends in a plurality of adjacent holes 107 in the cover part 8 base plate 108 to allow a sound signal issued by the signaling means on a PCB (not shown) to be perceived by the animal. An annular groove 109 serves for receiving the first sealing ring 9 to ensure seal-tight connection between cover part 8 and base plate 2.

[0131] FIGS. 20 and 21 are perspective views of a PCB 110 in conjunction with a motor unit 111, signaling means, and means for wireless communication 26 seen oblique from above. The PCB 110 is shown without the actual electric circuit of the board. Ordinary electronic components known to the person skilled in the art are not shown.

[0132] A second drive means is a second toothed wheel 112 on a rotary shaft 113 of the motor unit 111. As seen better in FIG. 23, in the assembled state of the food dispenser 1 the second toothed wheel 112 protrudes out of the drive hole 56 in the base plate 2 for engaging the first drive means 63 of the synchronization ring 6 to rotate the feeding bowl 3 in response to actuation of the actuator 7 by pushing the second lid part 5 so that the motor unit 11 is switched on. A sound issuing means 114 of the signaling means are arranged above the microphone 105 in the assembled state of the food dispenser 1.

[0133] A plate spring 115 protrudes upright from the PCB 110 and out of the plate spring opening 55 in the base plate 2 when the PCB is mounted in the bottom of the receptacle 55, thus to the base plate 2. The plate spring 115 is pressed down when the synchronization ring 6 rotates into electrical contact with angular control switch 116 of the rotary mechanism. When the feeding bowl 3 starts to rotate an angle corresponding to a food compartment the plate spring 115 will be pressed down against the control switch 116 to close an electric circuit controlling said degree of angular rotation. At the end of this predetermined rotation the electric contact between the plate spring 115 and the control switch 116 is terminated. The plate spring 115 may e.g. slide against an annular step 117 tapering in the rotation direction between to angularly spaced apart stops 76, so as to release spring force and disrupt contact. This procedure is repeated each time the actuator 7 is operated until the control unit determines that all food compartments 77 are now empty.

[0134] A spacer disk 118, such as a rubber disk 118, and guide tabs 119 serve to position the PCB 110 correctly inside the receptacle 55 of the base plate 2.

[0135] A transceiver 120 with an antenna 26 provides for wireless communication between several food dispensers 1. The wireless communication system has a separate switch and contact 121, and the overall control of the computer program for operating the food dispenser 1 is done by suitable programmed microprocessor 122.

[0136] FIG. 22 shows the food dispenser 1 in an assembled state, in dispensing position where a food compartment 77 is located aligned with the outlet opening 85 of the second lid part 4.

[0137] How the different individual structural components of the food dispenser 1 are interconnected and positioned in relation to each other becomes are seen in the perspective sectional fragmentary view of FIG. 23 taken along line XXII-XXII in FIG. 22 and seen inside the food dispenser 1 and from the sectional view of FIG. 24. For illustrative purposes PCB and electronics are left out in FIG. 23. The sectional views illustrate further how the various main components are coupled together as already discusses in detail in relation to the previous figures.

[0138] FIG. 25 shows three food dispensers 1a,1b,1c in the method according to the present invention. The food dispensers 1a,1b,1c are all charged with food in respective six food compartments 77, and arranged in a motivating and exercising feeding setup within wireless communication.

[0139] A first food dispenser 1a, a second food dispenser 1b, and a third food dispenser 1c are arranged within wireless communication distance. All three has power switched on, and the signaling means and the wireless communication means are on. The operator starts the first food dispenser 1a to issue a sound signal via the microphone 105 and/or light signal via the second lid 5. The sound signal and/or light signal attracts the attention of a dog 123 to use its paw 124 to stop the noise or light, however in its attempt to deactivate the issued signals the dog 123 manipulates the actuator head 88 so that the motor unit becomes activated and rotates the feeding bowl 3 an angle corresponding to a food compartment to discharge food from a first of six charged food compartments 77. At the same time the wireless communication means of the first food dispenser 1a has identified the subsequent food dispenser 1 of the setup within wireless communication, and transmitted a control signal to the second food dispenser 2b that triggers this subsequent second food dispenser 1b to issue a sound signal and/or light signal which the dog 123 now knows better how it get food from a food dispenser 1a. So the dog runs towards the second food dispenser 1b and performs the same action as with the first food dispenser 1b. These steps are repeated with the third food dispenser and until all food compartments are empty, as indicated by double arrows in FIG. 25. In the method according to the food dispenser the food dispensers are placed as desired. Placement may e.g. be random, specialized, be in different or same rooms, and the control unit be programmed to identify the next food dispenser closest to the previous food dispenser, taking accounts of which food dispenser was used last, and counting the number of rotation a certain food dispenser has rotated.
