A water recreation dock for providing access into and out of the water comprising a main deck platform carried by a dock frame. A stationary platform forms a first part of the main deck platform which is supported above the water on the dock frame. A movable platform forms a second part of the main deck platform which has a raised position and a lowered position. A landing section and a walkway section are included in the movable platform. In the raised position, the landing section and walkway section are located generally in a common horizontal plane with the stationary platform above the water. In the lowered position, the landing section is submerged and the walkway section is partially submerged as extending from the stationary platform to the landing section to provide access into and out of the water.

The dock of claim 1 including a drive assembly carried at least in part by said stationary platform; said drive assembly operatively connected with said movable platform for raising and lowering said movable platform.3. The dock of claim 2 wherein said drive assembly includes a vertical displacement mechanism extending downward beneath said stationary platform, and a drive motor carried by said stationary platform above the water; said vertical displacement mechanism carrying said movable platform, and said drive motor operatively connected with said vertical displacement mechanism; said drive motor and said vertical displacement mechanism cooperating to move said platform between said raised and lowered positions.4. The dock of claim 3 wherein said vertical displacement mechanism includes an elongated shaft extending vertically beneath said stationary platform, and a lateral support arm extending perpendicular to said elongated shaft carrying said landing section; said lateral support arm traveling on said elongated shaft when said drive motor is operated to raise and lower said landing section.5. The dock of claim 4 wherein said lateral support arm has a first portion carrying a threaded collar for cooperating with threads included in said elongated shaft to raise and lower said lateral support arm; said lateral support arm having a second portion engaging said landing section; said drive motor rotating said shaft to cause said threaded collar to travel along said threads of said elongated shaft so that said lateral support arm raises and lowers said landing section.6. The dock of claim 4 including a guide member carried by said upper dock frame for housing said elongated shaft; said guide having an arm slot extending along the length of said guide member for allowing said lateral support arm to be moved vertically along said elongated shaft while extending through said guide; and said landing section abutting said guide to restrict lateral movement of said movable platform.7. The dock of claim 1 wherein said walkway includes a set of collapsible steps; said collapsible steps having a collapsed condition when said movable platform is in said raised position wherein each of said steps is folded into lateral alignment in a common horizontal plane with said stationary platform, and said collapsible steps having an expanded condition when said movable platform is in said lowered position wherein each of said steps is staggered in an inclined arrangement to provide steps leading from said stationary platform to said landing section.8. The dock of claim 7 including a step frame carrying said collapsible steps; said step frame having a first end pivotally connected to said stationary platform, and a second end pivotally connected to said landing section for moving with said landing section between said raised and lowered positions to collapse and expand said steps.9. The dock of claim 8 wherein each of said steps carries a support leg; said support leg slidably engaging said step frame to move between a support position holding said step in said expanded condition, and a retracted position allowing said step to move to said collapsed condition.10. A movable water access and support apparatus for use with an associated structure supported above a body of water, such as a dock, to provide access into and out of the water, said apparatus comprising:a movable platform having a raised position and a lowered position when attached to said associated structure; a landing section included in said movable platform adapted for being submerged in the water when attached to said associated structure; a walkway section included in said movable platform for extending between said landing section and said associated structure when attached to said associated structure; a drive assembly having a vertical displacement mechanism adapted for extending downward beneath said associated structure for mounting said movable platform to said associated structure; and, said vertical displacement mechanism including an elongated shaft adapted for extending vertically beneath said associated structure, a lateral support arm extending perpendicular to said elongated shaft adapted to carry said landing section, and a drive motor operatively associated with said elongated shaft; said lateral support arm traveling on said elongated shaft when said drive motor is operated to raise and lower said landing section; whereby said drive assembly is constructed and arranged for vertically displacing said movable platform between said raised position wherein said landing section and said walkway section are generally aligned in a common horizontal plane with said associated structure above the water, and said lowered position wherein said landing section is adapted to be submerged in the water with said walkway extending between said associated structure and said landing section. 11. The apparatus of claim 10 including a guide member carried by said associated structure for housing said elongated shaft; said guide having an arm slot extending along the length of said guide member for allowing said lateral support arm to be moved vertically along said elongated shaft while extending through said guide; and said landing section abutting said guide to restrict lateral movement of said movable platform.12. The apparatus of claim 10 wherein said walkway includes a set of collapsible steps; said collapsible steps having a collapsed condition in said raised position wherein each of said steps is folded into lateral alignment in a common horizontal plane with said upper surface of said associated structure, and said collapsible steps having an expanded condition in said lowered position wherein each of said steps is staggered in an inclined arrangement to provide steps leading from said upper surface of said associated structure to said landing section.13. The apparatus of claim 12 including a step frame carrying said collapsible steps; said step frame having a first end pivotally connected to said upper surface of said associated structure, and a second end pivotally connected to said landing section for moving with said landing section between said raised and lowered positions to collapse and expand said steps.14. A water recreation dock adapted for extending at least partially over a body of water to provide access into and out of the water comprising:a main deck platform supported above said water; a stationary platform forming a first part of said main deck platform; a movable platform forming a second part of said main deck platform having a raised position located generally in a common horizontal plane with said stationary platform above the water, and a lowered position wherein said movable platform is adapted for being at least partially submerged in the water below said stationary platform; a lock operatively associated with said stationary platform and said movable platform for locking said movable platform to said stationary platform in said raised position; and, said lock including a first locking part carried by said stationary platform, and a second locking part carried by said movable platform, wherein said first locking part engages said second locking part when said movable platform is in said raised position to interlock said stationary platform with said movable platform. 15. The dock of claim 14 wherein said movable platform includes a landing section and a walkway section; said landing section and walkway section located generally in a common horizontal plane with said stationary platform above the water when said movable platform is in said raised position; and said landing section submerged and said walkway partially submerged as extending from said stationary platform to said landing section when said movable platform is in said lowered position.16.
