DETAILED DESCRIPTION

FIGS. 1-3 illustrate a modular swim platform assembly 20 according to the present disclosure. The assembly 20 is shown mounted to bottom 22 of a stern 24 of a boat 26, however this is merely exemplary and it should be recognized that depending on the type of boat, the assembly 20 can be mounted to other surfaces of the boat 26, including for example the bow, the port side, or the starboard side of the boat 26. The type and configuration of the boat 26 is exemplary and can vary from what is shown.

The assembly 20 has a deck 28 that is movable relative to the boat 26. The deck 28 is located under the stern 24 in a retracted position (See FIG. 10). FIGS. 1 and 2 illustrate the deck 28 in an extended position, projecting outwardly from the stern 24 and providing a platform for standing. The deck 28 is located closer to the boat 26 in the retracted position than in the extended position.

Referring to FIG. 3, the assembly 20 has opposing mounting brackets 30 that are fixed to the bottom 22 of the stern 24. The mounting brackets 30 support the assembly 20 in all positions, including the above-described retracted and extended position. Each mounting bracket 30 has a base plate 32 and opposing slide rails 34 that are fixed to the base plate 32. An elongated slot 36 is defined between the slide rails 34 and generally extends along the length of the mounting bracket 30. An elongated recess 38 is formed between the base plate 32 and the slide rails 34. The slide rails 34 are fastened to the base plate 32 by fasteners 40. Optionally, the mounting brackets 30 can be made of aluminum and stainless-steel pressed against a Delrin AF material.

The assembly 20 also has a pair of slidable base frames 42. Each base frame 42 has an upper end with a T-profile 46, a rearwardly extending supporting arm 48, a downwardly extending supporting arm 50, and a forwardly extending supporting arm 51 located between the rearwardly extending supporting arm 48 and the downwardly extending supporting arm 50. The T-profile 46 is disposed in the recess 38 and protrudes through the slot 36 of the corresponding mounting bracket 30. The base frames 42 are thus slide-able along the length of the recess 38, permitting sliding movement of the assembly 20 into and out of the extended and retracted positions shown in FIGS. 1 and 2. As shown in FIG. 4, an end cap 53 on the mounting brackets 30 limits outward sliding movement of the base frames 42 past the depicted extended position.

Referring to FIG. 3, an extension actuator 52 is configured to automatically extend and retract the assembly 20 into and out of the extended and retracted positions, as will be further described herein below. In the illustrated example, the extension actuator 52 is a hydraulically-actuated linear actuator having a cylinder 56 and a piston rod 58 that is extendible and retractable relative to the cylinder 56 under force of pressurized hydraulic fluid. Each extension actuator 52 has a first end 60 coupled to the stern 24 by a mounting bracket 62 having two bracket halves. The mounting bracket 62 facilitates pivoting of the first end 60 relative to the stern 24. Each linear actuator 54 also has a second end 64 that is pivotably coupled to the base frame 42 via an L-bracket 66 by a fastener 67. The L-bracket 66 projects rearwardly alongside the rearwardly extending supporting arm 48 and has a rearward end 68 that is fixed to an inside surface of the base frame 42 and a forward end 71 to which the second end 64 of the linear actuator 54 is pivotally coupled. As will be further described herein below, extension of the linear actuator 54 slides the assembly 20 into the extended position and retraction of the linear actuator 54 slides the assembly 20 into the retracted position. The type and configuration of extension actuator 52 can vary from that is shown, and in other examples could comprise any number of hydraulic and/electro-mechanical linear actuators, and/or the like.

Referring to FIGS. 1-3, the deck 28 includes a base platform 70 and a submersible platform 72. As will be further described herein below, the base platform 70 and submersible platform 72 are movable together into and between the extended position and the retracted position. The submersible platform 72 is further pivotable relative to the base platform 70 from the extended position to a deployed position (FIG. 1) that is below the base platform 70. A pair of submersible frames 74 are fixed to the bottom 76 of the submersible platform 72. Referring to FIG. 3, the submersible frames 74 each have a forwardly extending supporting arm 78 and a downwardly extending supporting arm 79.

Now referring to FIG. 3 and FIGS. 8-10, the base platform 70 is fixed on and supported by the rearwardly extending supporting arms 48 of the base frames 42. A pivot linkage 80 pivotably couples the submersible platform 72 to the base frames 42 such that the base platform 70 and submersible platform 72 are movable together into and between the retracted position and the extended position, and further such that the submersible platform 72 is movable relative to the base platform 70 into and between the extended position and the deployed position. The type and configuration of the pivot linkage 80 can vary from what is shown and described. In the illustrated example, the pivot linkage 80 is configured such that the submersible platform 72 pivots along an arc 82 (FIG. 8) from the extended position, initially downwardly and outwardly from the base platform 70 and then downwardly and back inwardly towards the base platform 70.

The pivot linkage 80 has opposing first pivot arms 84 and opposing second pivot arms 86. Each first pivot arm 84 has an inner end portion 88 that is pivotably coupled to the forwardly extending supporting arm 51 of the respective base frame 42 at a first inner pivot point 90. Each first pivot arm 84 further has an outer end portion 92 that is pivotably coupled to the forwardly extending supporting arm 78 of the respective submersible frame 74 at a first outer pivot point 94. Each second pivot arm 86 has an inner end portion 96 that is pivotably coupled to the downwardly extending supporting arms 50 of the respective base frame 42 at a second inner pivot point 98. Each second pivot arm 86 further has an outer end portion 100 that is pivotably coupled to the downwardly extending supporting arm 78 of the respective submersible frame 74 at a second outer pivot point 102. The first pivot arms 84 are located above the second pivot arms 86. Each first pivot arm 84 comprises an elongated upwardly pair of curved bars and each second pivot arm 86 comprises an elongated downwardly pair of curved bars. The pivot points are provided by fasteners secured in through-bores in the pairs of curved bars. The first inner pivot point 90 is located above the second inner pivot point 98. The first outer pivot point 94 is located above the second outer pivot point 102. The first inner pivot point 90 is located forwardly of the second inner pivot point 98. The first outer pivot point 94 is located forwardly of the second outer pivot point 102. Again, the type and configuration of the pivot linkage 80 can vary from what is shown. In the illustrated example, the above-described pivot linkage 80 can be referred to as a four-bar linkage.

A deployment actuator 104 is configured to automatically move the submersible platform 72 into and between the extended position and the deployed position. In the illustrated example, the deployment actuator 104 includes a pair of hydraulically-actuated linear actuators 106, each having a cylinder 56 and a piston rod 58 that is extendible and retractable relative to the cylinder 56 under force of pressurized hydraulic fluid. Each linear actuator 54 has a first end 108 pivotably coupled between the rearward end 68 of the L-bracket 66 and the base frame 42 and a second end 110 pivotably coupled to the respective second pivot arm 86 between the inner and outer end portions 96, 100. The first end 108 is thus positioned vertically higher than the second end 110. Extension of the linear actuators 106 pivots the submersible platform 72 downwardly along the arc 82 into the deployed position. Retraction of the linear actuators 106 pivots the submersible platform upwardly along the arc 82 into the extended position. The type and configuration of extension actuator 52 can vary from that is shown, and in other examples could comprise any number of hydraulic and/electromechanical linear actuators.

Referring to FIG. 7, base platform 70 has an outer profile 112 having a generally semi-circular shape. The submersible platform 72 has an inner profile 114 having a generally semi-circular shape that follows and is located adjacent to the semi-circular shape of the outer profile 112 such that the base platform 70 and submersible platform 72 provide a contiguous platform surface in the extended position on which an occupant of the boat 26 can stand. With further reference to FIGS. 7 and 8, the pivot linkage 80 is specially configured such that from the extended position the submersible platform 72 is pivotable rearwardly out of lateral alignment with the base platform 70 along the arc 82 and then forwardly or inwardly towards the submersible platform 72 and below but also back into lateral alignment therewith. Thus the assembly 20 appears the same when viewed from the top, see FIG. 7, in both the extended position and the deployed position.

Referring to FIG. 1, the assembly 20 further includes an operator input device 120 configured to control a control system 122. The control system 122 is configured to selectively actuate the extension actuator 52 and the deployment actuator 104 to reposition the assembly 20 into and between the positions shown in the drawings. The control system 122 can be any conventional device for controlling the extension actuator 52 and deployment actuator 104. In examples wherein the extension actuator 52 and deployment actuators 104 are hydraulically actuated, the control system 122 can include one or more conventional hydraulic pumps, valves and/or switching devices for controlling a flow of pressurized hydraulic fluid to the extension actuator and/or deployment actuator 104. However as mentioned above, the actuators do not necessarily have to be hydraulic actuators, and for example can comprise electro-mechanical devices such as one or more electric motors, and/or the like. The type and configuration of operator input device 120 can be any conventional device for inputting a command to or otherwise controlling the control system 122, including for example a mechanical switch, manual lever, push button, joystick, and/or the like. In certain examples, the operator input device 120 can include a touch screen for inputting to a programmable controller for controlling the actuators 52, 104.

Operation of the assembly 20 will now be described with reference to FIGS. 4-10, in sequence. Referring to FIGS. 4 and 10, the assembly 20 is normally positioned in the retracted position when the boat 26 is cruising in open water. As shown, the deck 28 is retracted under the stern 24 via retraction of the extension actuator 25, such that the entire base platform 70 and a majority of or all of the submersible platform 72 are located under the stern 24. The deployment actuator 104 is also retracted, which causes the submersible platform 72 to be laterally aligned with (parallel to and inline with) the base platform 70 and located adjacent to the bottom 22 of the stern 24.

Referring to FIGS. 5 and 9, when for example the boat 26 is at rest, the operator can operate the operator input device 120 to cause the extension actuator 52 to extend the extension actuator 5, which slides the entire deck 28, including the base platform 70 and submersible platform 72 rearwardly, i.e. outwardly relative to the stern 24. The deck 28 is positioned adjacent to the rear of the stern 24, and the base platform 70 and submersible platform 72 remain laterally aligned such that the deck 28 provides an extended platform on which the operator can step onto and stand.

As shown in FIGS. 6 and 8, when desired, the operator can operate the operator input device 120 to cause the control system 122 to actuate the deployment actuator 104 to extend the linear actuators 106, which pivots the submersible platform 72 downwardly along arc 82 into the deployed position. As described herein above, in the deployed position the submersible platform 72 is in lateral alignment with the base platform 70 so that, as shown in FIG. 7, the inner profile 114 is vertically aligned with the outer profile 112. In this position, the assembly 20 provides an ergonomic step for a swimmer to step down from the base platform 70 to the submersible platform 72, which is typically located under water. In this position, the submersible platform 72 also provides an ergonomic seat on which a swimmer can sit in the water. In this position, the base platform 70 also provides an ergonomic arm rest for the swimmer seated on the submersible platform 72.

Optionally, movement of the deck 28 from the retracted position to the extended position and movement of the submersible platform 72 from the extended position to the deployed position can occur via single actuator and in a one-step, automated process. For example, by manually operating the operator input device 120 the above-described movements of the assembly 20 can be carried based on a single command for example based upon a manual input to a touchscreen or manually holding down a selector switch or button, and/or the like. In the illustrated example having hydraulic actuators, only one hydraulic pump is needed as the extension actuator 52 and the deployment actuator 104 can be connected in series via a set of overpressure valves. This allows the operator to activate the platform with one button and when it reaches the full extended position it would automatically begin to lower to the desired depth in a continuous motion. To retract the assembly 20, the operator would activate the button to raise the submersible platform 72 would be raised raise to its full height shown in FIG. 5 and then retract again to the retracted position shown in FIG. 4.

Viewed in series, FIGS. 8-10 show movement of the assembly 20 from the deployed position (FIG. 8) to the extended position (FIG. 9) and then to the retracted position (FIG. 10). As described above, these movements can be automated based upon an input to the operator input device 120, and movement optionally can be fluid from one position to the next depending on the input.

Advantageously, the present disclosure provides examples of modular swim platform assemblies that are compact and configured for implementation on boats having one or more marine drives in an ergonomic and space-saving arrangement. The illustrated example can be efficiently implemented on the stern of a boat having twin stern drive units, as shown, without interfering with performance.

The present disclosure thus provides embodiments of boats and modular swim platform assemblies for boats. The modular swim platform assemblies comprise a deck that is movable relative to the hull into and between a retracted position in which the deck is under the hull and an extended position, wherein the deck is extended away from the hull and provides an extended platform on which an occupant of the boat can stand. The deck comprises a base platform and a submersible platform, the submersible platform being movable out of the extended position with the base platform remaining in the extended position, and particularly the submersible platform being movable out of the extended position to a deployed position below the base platform. In the deployed position, the submersible platform provides a seat for the occupant to sit in the water and the base platform provides an armrest for the occupant. The deck slides into and between the retracted position and the extended position and wherein the submersible platform is pivotable relative to the base platform into and between the extended position and the deployed position. A pivot linkage couples the submersible platform to the base platform so that the base platform and the submersible platform are movable together into and between the retracted position and the extended position, and further so that the submersible platform is movable relative to the base platform into and between the extended position and deployed position. The base platform has an outer perimeter and the submersible platform has an inner perimeter that is aligned with the outer perimeter of the base platform both when the submersible platform is in the extended position and when the submersible platform is in the deployed position. An actuator system controls automatic movement of the deck from the retracted position into the extended position and then controls automatic movement of the submersible platform from the extended position into the deployed position. The operator input device further controls automatic movement of the submersible platform from the deployed position to the extended position and then controls automatic movement of the deck from the extended position to the retracted position.
