My dog Sugar using dad's foot as an automatic chin scratcher. The cat is Berry.
To cope with the demands of his golden retriever that wants constant petting, Elias Fhagen-Smith designed an automatic dog scratcher. He mounted a dog brush to a motorized rotating arm that is triggered when the canine steps onto a pressure mat, retrofitted from a Halloween fright device.
FIG. 1 illustrates an automated back and belly scratcher 10, having a shaft 12 having a first end 12A and a second end 12B, having a hand-shaped portion 20 affixed to the first end 12A, and having a handle 14 affixed to the second end 12B. The hand-shaped portion 20 has five fingers 22, each having a fingertip 22T having a fingernail 22N. The hand-shaped portion 20 contains a small motor 30 therein, for selectively moving the fingers 22, as will be described. The handle 14 is held within one of the hands of a user while using the hand-shaped portion 20 to scratch or massage the back or belly of a user or of a pet such as a dog or a cat.

A variety of backscratchers are available for moving a contact surface against hard-to-reach areas upon a person's back. However, these back scratchers have a number of substantial limitations. In particular, most existing back scratchers are manually operated and have “scratching portions” which are rigid and incapable of motion. This may not present a serious problem if the scratcher is used only intermittently, or for a short period of time. However, manually scratching the back or belly of a user or of a pet such as a dog or a cat may become difficult and tiring after an extended period of time. Accordingly, there is a need for an automated back and belly scratcher having a hand-shaped portion having fingers, and having a motor contained within the hand-shaped portion for selectively moving the fingers, in order that the user can scratch the back or belly of the user or of a pet for an extended period of time without becoming tired.The invention is an automated back and belly scratcher having a telescopically adjustable shaft and having a hand-shaped portion attached at one end of the shaft. The hand-shaped portion has fingers that may be used for scratching or massaging the back or belly of a user or of a pet such as a dog or a cat. The shaft has a plurality of segments which may be telescopically positioned within one another, in order to maximally extend the shaft, or alternately, to retract the shaft into a storage position. The back and belly scratcher is provided with a motor in mechanical contact with the fingers of the hand-shaped portion, thereby enabling a user to selectively move the fingers by activating the motor. The motor has two modes of operation, one that produces a repetitive finger motion comprising successively and sequentially tapping each of the different fingers, in turn, and one that comprises simultaneous in-and-out finger motion of all of the fingers.It is an object of the invention to provide an automated back and belly scratcher that is well suited for scratching or massaging the back or belly of a user or of a pet such as a dog or a cat. Accordingly, the back and belly scratcher has a hand-shaped portion having elongated fingers that are well suited for scratching or massaging the back or belly of a user or of a pet.Can't believe there's still no automated head scratchers on the market. I'm getting tired of waiting. Sigh. (See my butt scratcher for dogs video too.)
