## Abstract

A trailer tongue assembly includes a tongue body, a ball clamp, an actuating device, and a control unit. The tongue body is coupled to a frame and includes a ball socket that defines a socket volume. The ball clamp is located within the tongue body and translates internally within the tongue body so as to selectively protrude into and out of the socket volume. The actuating device is in communication with the ball clamp and is configured to position the ball clamp within the socket volume. The control unit is in communication with the actuating device and is configured to regulate the operation of the actuating device. In all, the tongue body surrounds the ball clamp, the actuating device and the control unit.

## Claims

### Claim 1

A trailer tongue assembly, comprising:
a tongue body in communication with a frame of a trailer, the tongue body including a ball socket defining a socket volume;
a ball clamp within the tongue body and configured to translate therein so as to selectively protrude into and out of the socket volume;
an actuating device in mechanical communication with the ball clamp and configured to position the ball clamp within the tongue body; and
a control unit in communication with the actuating device and configured to regulate operation of the actuating device;
wherein the tongue body surrounds the ball clamp, the actuating device and the control unit.

### Claim 2 (depends on 1)

The assembly of claim 1, wherein the socket volume is larger than 3 inches in diameter.

### Claim 3 (depends on 1)

The assembly of claim 1, wherein the socket volume is less than 2.5 inches in diameter.

### Claim 4 (depends on 1)

The assembly of claim 1, wherein movement of the ball clamp is linear.

### Claim 5 (depends on 1)

The assembly of claim 1, wherein the ball clamp remains within the tongue body during and after the movement.

### Claim 6 (depends on 1)

The assembly of claim 1, wherein the ball clamp includes a cupped recess along a front face that has a defined radius.

### Claim 7 (depends on 6)

The assembly of claim 6, wherein the radius is equal to that of the socket volume.

### Claim 8 (depends on 6)

The assembly of claim 6, wherein the radius is not equal to that of a radius of the socket volume.

### Claim 9 (depends on 1)

The assembly of claim 1, wherein the actuating device includes an electric motor.

### Claim 10 (depends on 1)

The assembly of claim 1, wherein the control unit is configured to detect a size of a hitch ball within the socket volume.

### Claim 11 (depends on 10)

The assembly of claim 10, wherein the size of the hitch ball is determined by monitoring a longitudinal location of the ball clamp within the tongue body.

### Claim 12 (depends on 1)

The assembly of claim 1, wherein the control unit is configured to monitor a resistive force acting upon the ball clamp and compare the resistive force to a predetermined level.

### Claim 13 (depends on 1)

The assembly of claim 1, further comprising:
a remote electronic device in communication with the control unit for the transferring of electronic command data.

### Claim 14 (depends on 13)

The assembly of claim 13, wherein the remote electronic device includes an executable software application for an operation of the control unit.

### Claim 15 (depends on 13)

The assembly of claim 13, wherein the tongue body includes an electronic port in communication with the control unit.

### Claim 16 (depends on 15)

The assembly of claim 15, wherein the electronic device is configured to plug into the electronic port to communicate with the control unit.

### Claim 17 (depends on 15)

The assembly of claim 15, wherein the electronic port facilitates a broadcast and receipt of wireless command data.

### Claim 18 (depends on 1)

The assembly of claim 1, wherein an access to an interior of the tongue body is limited to the ball socket.

### Claim 19 (depends on 1)

The assembly of claim 1, wherein the ball clamp is secured within the socket volume when not in use.

### Claim 20 (depends on 1)

The assembly of claim 1, further comprising:
a side hole in the tongue body and a side hole in the ball clamp and a pin for passage through the side holes in the tongue body and the ball clamp.
