(D) DETAILED DESCRIPTION OF THE DRAWINGS

[0021] i. Structure of the Invention

[0022] The device of the present disclosure is permanently mounted directly to the body of a water vehicle or boat 10 and therefore eliminates dependence on external vehicles or other forms of assistance when launching a beached boat from ground into the water. The size of the device 12 in the retracted position can range from twenty-four to forty-six inches long, or more preferably from thirty to forty inches long, or even more preferably at thirty-six inches long. The shove-off device 12 is mounted to the boat 10 by a set of mounting brackets 14, 15. The adjusting linear actuator, such as a slide-rail linear actuator 16, and the approach linear actuator 18 attach to the boat 10 by mounting brackets 14, 15 at separate attachment points as seen in FIG. 1. The mounting bracket 14 is attached to the slide-rail linear actuator 16 by a pivot joint or other device as known in the art. The second mounting bracket 15 is attached to the approach linear actuator 18 by a fixed joint. A mechanical power device 20 is mounted to the slide-rail linear actuator 16, and the mechanical device 20 is connected to a power supply 22. At the ends of linear actuators 16, 18 that are not mounted to the boat 10, the slide-rail linear actuator 16 and the approach linear actuator 18 operatively attach to each other at a common pivot point 24 by way of multiple switch joints or other devices known in the art. One end of extendable and retractable rod 26 is attached where the slide-rail linear actuator 16 and approach linear actuator 18 meet at point 24. At the other end of the rod 26 is a flat, flexible ground contact pad 28. The rod 26 is optionally thirty-six inches upon extension. The length of the rod 26 in the extended position matches the length of the retracted device, less four inches or so. In the device's 12 retracted state, with the rod 26 contracted towards the water vehicle 10, the device 12 itself is preferably thirty-six inches long. For example, a device 12 that is forty inches long when retracted would be equipped with a rod 26 that is thirty-six to forty inches long and upon rod 26 extension the total length of the device 12 would be seventy-two to seventy-six inches long.

[0023] In order to power the shove-off device, a control system 30 is provided on the boat 10. The control system 30 includes an on/off switch, a power supply 22, and a processor 32. The control system 30 is preferably located near the captain's chair 34 as seen in FIG. 2. The control system 30 is remotely connected to the power supply 22. The power supply 22, in turn, is connected to the mechanical power device 20 located on one of the force creating devicesthe slide-rail linear actuator 16 or the approach linear actuator 18. The power supply 22 can be a 12 VDC power supply already common on most boats, but can include any alternative source of power.

[0024] In an alternative embodiment of the invention, the connection points between the extendable and retractable rod 26, slide-rail linear actuator 16, approach linear actuator 18, and contact pad 28 can be altered. The contact pad 28, for example, could be connected to at least one of the linear actuators 16, 18 by a swivel, ball joint, or fixed attachment point.

[0025] In an alternative embodiment of the invention, the approach angle of the slide-rail linear actuator 16 and the approach linear actuator 18 is fixed.

[0026] In an alternative embodiment of the invention, the vehicle shove-off device 12 can be mounted to the sides of the water vehicle 10 as seen in FIG. 3, or to the top of the water vehicle 10.

[0027] In an alternative version of the invention, the operable length of the vehicle shove-off device when in the retracted position ranges from twenty four to forty six inches long, or more preferably thirty to forty inches long.

[0028] ii. One Cycle of Operation

[0029] Typically when the boat is released or launched into the water, the operator of the boat must attach the boat to an external vehicle or rely on multiple people to push the boat into the water. But with the presently disclosed device 12, outside assistance is not neededthe operator can launch a boat with the push of a button.

[0030] A remotely operable control system 30 near the captain's chair 34 activates the power supply 22 of the shove-off device 12 and initiates the pressing motion required to launch the beached boat from land into the water. Activation of the control system 30 connects the power supply 22 to the mechanical power device 20. The mechanical power device 20 enables the subsequent movement of the force creating devicesthe slide-rail linear actuator 16 and the approach linear actuator 18as well as extension of the retractable rod 26. During operation, the mechanical power device 20 drives the relative movement between the slide-rail linear actuator 16 and the approach linear actuator 18 to assist in creating pressing motion through contact pad or pads 28, which motion is required to propel the boat in the opposite direction and into the water.

[0031] The pivot joint of mounting bracket 14 is adapted to allow the slide-rail linear actuator to rotate around a z-axis. The fixed joint of the second mounting bracket 15 is adapted to allow the approach linear actuator 18 to adjust the position of the mechanical device 20 and slide-rail linear actuator 16 to move in accordance with the desired approach angle.

[0032] The slide-rail linear actuator 16 is configured to adjust the approach angle of the water vehicle. The angle between the slide-rail linear actuator 16 and the approach linear actuator 18 is within a range of three to six inches, the approach linear actuator adjusting the angle of the rod 26 to the ground surface. During this movement, the slide-rail linear actuator 16, the approach linear actuator 18, and the extension of rod 26 apply force to contact pad 28. To accomplish this motion, the rod 26 of the device shifts from a compact, retracted position on its corresponding slide-rail linear actuator 16 to an extended position. The retracted position of the rod 26 allows
