TRAINING TOILET
Reference to Related Application
[0001] This application claims priority to U.S. nonprovisional patent application No. 13/338,889, filed December 28, 2011, which is incorporated herein in its entirety by reference.
[0002] This invention relates in general to training toilets and more particularly to a design which can be adapted for training animals such as dogs and cats or for the training of a baby.
Background Of The Invention
[0003] It is known to use a positive reinforcement message during toilet training to get use of the toilet on a regular basis. The known training toilets are not as widely used as might be the case for a number of reasons including, Applicant believes, a combination of cost, effectiveness and optimum reinforcement.
[0004] Accordingly, it is a major object of this invention to provide a training toilet that at a reasonable price will be effective and provide an appropriately optimized reinforcement message.
[0005] It is a related purpose of this invention to provide the above in a context which will be comfortably used by the party involved and also without requiring expensive or redundant features. Brief Description
[0006] In brief, this invention involves a framework for holding a platform for receiving the trainee. The platform can be a seat or a pad or a base for holding kitty litter. The trainee can be a pet such as a dog or cat or can be a child. The presence of the trainee in the space above the platform is detected by a switch or sensor that provides a signal that enables a microcontroller to process a program that involves playing one or two audible reinforcement messages to the trainee. The sensor that provides this enabling signal to the microcontroller can be a weight responsive switch or a motion detector. Optimally, these messages will be in the voice of someone with whom the trainee is familiar such as an owner or parent.
[0007] It is important to provide a message when the trainee (animal or human child) gets off or out of the training toilet. Preferably, this message has to be provided at least a predetermined time period after the trainee is received on or in the training toilet to assure that the trainee has had time to use the toilet. Thus in a preferred embodiment, when the trainee gets on or in the training toilet and the enabling switch is actuated, a timing circuit causes a predetermined time period to lapse before the exit reinforcement message can be played
[0008] Thus a combination of time lapse and exit response signal provides the a positive reinforcement message at a time which assures that the trainee has completed its waste operation. This will be referred to herein as Mode I.
[0009] A Mode II embodiment adds a feature to the Mode I embodiment. In Mode II, the microcontroller is programmed to respond to actuation of the enabling switch to further provide an initial positive reinforcement audio message when the trainee enters or gets onto the training toilet. This entering message is preferably different from the exit message. [0010] A Mode III embodiment is like the Mode I embodiment except that there is no time lapse. The exit positive reinforcement audio message is played whenever the trainee gets off of or exits from the toilet.
[0011] A mode IV embodiment is like the mode II embodiment except that there is no time lapse. The entering positive reinforcement message is played when the trainee enters the toilet and the exit reinforcement message is played whenever the trainee exits the toilet.
[0012] The microcontroller is set by the user to the desired mode.
[0013] Common to all four modes is that a positive reinforcement message may be played when the trainee exits the toilet.

[0018] The three embodiments described herein are capable of operating in any one of four modes. The three embodiments are configured and sized for use with different trainees. All three embodiments operate in response to an enabling signal generated by a sensor (switch or motion sensor) changing state thereby providing the signals that causes a microcontroller 32 to execute one of the four programs preselected by the user. Each of the three embodiments can be set by the user to any one of the four modes described herein.
[0019] The first embodiment, shown in FIGs. 1, 2 and 3 is to a dog training toilet having a mesh 16 supported on a step tray 12 to receive the trainee, presumably a dog. A frame 14 holds the mesh 16 and step tray 12. The frame can hold other elements such as a moisture absorbing layer, as is known in the art. The step tray 12 is attached to a platform 10, which platform holds the electronics.
[0020] The step tray 12 of the FIG. 1 device includes a flexible resilient slightly upward curved layer 18 which responds to the weight of the dog on the mesh 16. A normally open electric switch 30 is positioned between this curved resilient layer 18 and a rigid base 10 . When the dog steps into the space above the mesh 16, the weight of the dog on the mesh 16 is transmitted to the flexible layer 18, causing the layer 18 to deflect downwardly and thus close the switch 30.
[0021] Closing the switch 30 provides an initiating enabling signal to the microcontroller 32. The microcontroller 32 then operates in one of the operator preselected modes to provide one or two audio messages. This FIG. 1 embodiment is adapted to train a dog but any appropriately sized animal can be the trainee.
[0022] FIG. 4 shows the electronic control arrangement that is associated with the user selecting any one of four modes of operation for the device of this invention. Closing of the enabling switch 30 Provides an initiating signal that causes the microcontroller 32 to control the timing of the one or two messages from the memory 34 that is delivered to the speaker 36 through the speaker driver 38.
[0023] The four position mode switch 40 determines the operation of the microcontroller 32 so that the system will operate in one of the four operating modes described above. The mode switch 40 is designed and positioned so that the user can select any one of the four modes. Each of the four leads 40a, 40b, 40c and 40d, provides a separate one of four selection signals to the microcontroller 32. Each of those four selection signals initiates a separate one of the four modes operation of the
microcontroller 32. The four modes are set forth in the Brief Description.
[0024] It is known in the art how to program the microcontroller 32 for operation in each of the four modes. The change in state of the switch 30 provides a signal indicating that an animal has entered or exited from the space in which the trainee is received. In particular, when the trainee exits from the toilet, the switch 30 opens provides as an exiting signal a state change signal that controls or affects the timing of the playing of the exit message.
[0025] Battery 41 power is normally on at all times. Change in state of the enabling switch 30 is the signal that the microprocessor 32 is to operate in accordance with the operator preselected mode. The switch 30 is changed into its closed state in the dog toilet when the dog steps into the toilet and depresses the flexible resilient slightly domed layer 18. The switch 30 is changed into its open state when the trainee gets out of the toilet
[0026] The switch 30 is a motion detector switch 53 in embodiments adapted for a cat trainee or motion detector switch in embodiments adapted for human child trainee.
[0027] The battery 41 is a convenient source of energy for operating this device. The battery provides power at all times in the embodiments shown. However, a manually operated line switch (not shown) can be included to save battery power during long term non-use.
[0028] Memory 34 contains the positive reinforcement message or messages to be coupled to the speaker 36 in accordance with the mode selected by the user. The memory 34 may contain two messages so that in the modes II and IV, an entrance message is played in addition to the exit message played when the animal leaves the toilet.
[0029] It should be noted that the microphone 44 which is used to input the message for the memory 34 requires an analog to digital output unit which can be part of the microphone 44 or as a separate downstream item (not shown). Similarly, a digital to analog device (not shown) would be incorporated at the input to the speaker driver 38 as part of the driver 38 or as a separate item.
[0030] In another embodiment, a frame provides a space or enclosure which is adapted to receive an animal such as a cat. Once the cat enters into the space, a motion sensor is activated by the cat's movement to close the switch 30. Exit of the cat causes the motion detector to generate the open state of the switch 30. The floor of the interior of this device can be a standard arrangement such as one that employs kitty litter.
[0031] A further embodiment of the device of this invention adapted to the training of a young human child. The device can be employed with either a weight detector switch which is responsive to the weight of the child or a motion sensor which is responsive to the movement of the child getting onto or off of the toilet involved. In the device, a frame provides a seat having a back surface within which is mounted an appropriate motion sensor to provide the enabling signal required for the operation of the FIG. 4 electronic and message providing arrangement. Once the enabling signal has been established, then the FIG. 4 arrangement operates in the one of the four modes preselected by the user or trainer or guardian of the child involved. [0032] It is preferred that all four modes be provided in each embodiment. But a less flexible embodiment could be created that would provide fewer than all four modes.
