DESCRIPTION OF PREFERRED EMBODIMENTS

The floating platform comprises a floating platform 2. The floating platform may be a floating dock or a raft or other platform that will float in water. The floating platform may be formed of wood, plastic or other materials that will float in water. As shown in the drawing figures, the floating platform is formed of a plurality of individual floating units 12 that are connected to form a rectangular floating platform. The floating platform as shown in FIG. 1 also has a generally level and planar top surface and can be used as a boat dock with the boat stored on top of the boat dock. The floating platform may be used as a staging area for tools and materials, or the floating platform may be used as a walkway, such as a catwalk. The floating platform may be formed in shapes other than a rectangular shape, and need not have a planar top surface.

Forming the floating platform 2 of individual floating units 12 allows the floating platform to be constructed in a desired shape and dimensions, and also allows quick assembly of the floating platform. The floating platform has particular utility as a temporary facility that can be quickly assembled. Further, the use of individual units to form the floating platform, or the use of other modular construction of the floating platform, allows for easy transportation of the floating platform which can be assembled on site, and without the necessity of special highway transportation.

The invention allows the floating platform 2 to be held in place relative to another object 4 without substantial horizontal movement of the floating platform. However, the floating platform according to the invention allows vertical movement of the floating platform relative to the object due to changes in water levels due to tides, weather, or wave action. The object may be in position relative to the earth or the object may be another floating object. For example, the object could be a bulkhead fixed to the shore, or the object could be another floating platform or floating dock or the additional object could be a vessel, such as a ship or a boat. Whether the object is fixed or floating, the floating platform construct of the invention allows vertical movement of the floating platform relative to the object while holding the floating platform substantially in position horizontally, although the horizontal positioning may be adjusted.

Guide posts 6,8 are used to connect the floating platform 2 to the object 4. A preferred guide post is an elongated object that engages receptacles formed in and extending through the floating platform. The guide posts each comprise a horizontal blade 10 that extends from a side of the guide post and near a top of the guide post.

In a preferred embodiment, at least two brackets 14 are mounted to the object 4. Each bracket has opposing members 22,24 that allow the blade 10 of a guide post 6,8 to slidably engage the bracket between the opposing members. The blade may be formed to a desired length, so that the floating platform 2 may be horizontally spaced from the object at a desired distance. With the blade being slidable within the brackets, this distance may be adjusted as desired by the user. After positioning the blades between the brackets, the distance of the floating platform to the object is adjusted and the blade is fixed to a position within the brackets such as by using one or more set screws to hold the blade and the guide post in a horizontal position relative to the object. The guide posts thereby hold the floating platform in a horizontal position relative to the object. The blades of the guide posts are positioned above the floating platform.

In one embodiment the brackets 14 are mounted under the object and/or under the floating platform. The blades of the pile guides slidably engage the brackets as described. Mounting the brackets and pile guides on a lower surface rather than a top surface of the object and/or floating platform removes and obstruction or tripping hazard from the top of the object and/or floating platform.

The guide posts 6,8 engage receptacles formed in and extending through the floating platform 2. The guide posts are fixed in position relative to the object as described above, but the floating platform moves vertically relative to the guide posts as the floating platform floats in changing water levels. The fit of the guide posts within the receptacles is such that the receptacles, and therefore the floating platform, can traverse the guide posts in a vertical direction. The floating platform can move vertically independent of the object 4 to which the floating platform is attached. In this manner, if the object is fixed to the earth, changes in water levels do not submerge the floating platform. Similarly, if the floating platform is attached to a floating object, such as a large vessel, the floating object has less tendency to pull the floating platform under the water in the event of violent wave action.

The guide posts 6,8 may be formed to a length that is required by the application. For example, if the object 4 is fixed to the earth and the floating platform 2 is subject to two (2) meter tides, the guide posts may have a length of three (3) meters or more. In some applications it may be desirable to have a stop on the guide posts. The stop may be a pin inserted through a void 18 of the guide post so that the floating platform does not disengage from the guide post in the event of an extremely low water level due to tides, wave action or other causes.

The guide posts 6,8 may have a round cross section, and form an elongated cylindrical shape. If the guide posts are hollow, a cap may be placed over the top of the guide posts, so that the guide post may be used as a step for entering or leaving the floating platform 2. The receptacles are formed as voids having a complementary shape to the guide posts so that the floating platform moves vertically the guide posts as water levels change. The guide posts and receptacles could have other complimentary shapes. The receptacles and guide posts are preferred to be formed of polyethylene, and particularly high density polyethylene, which is extremely durable, corrosion resistant, and has low friction qualities that facilitate the movement required by the objects of the invention. Low density polyethylene may be used in other applications.

In a preferred embodiment, the guide posts have a specific gravity of less than 1.0 so that they float in water and provide buoyancy to retard deflection of the blade over time. In a specific embodiment the guide posts are hollow but are capped or otherwise sealed to prevent water intrusion into the center of the guide posts so as to provide buoyancy. The hollow guide posts may be made of materials having a specific gravity of less than 1.0. An example of such materials is polyethylene.

FIGS. 8-12 show an additional embodiment of the invention. The floating platform 102 may be a floating dock or similar platform that will float in water. The floating platform may be formed of floating members. The floating platform may be formed of wood, plastic or other materials that will float in water. The floating platform may have a hard surface, such as a surface formed of wood planking. The floating platform as shown in FIG. 8 may have a generally level and planar top surface. The floating platform may be configured for use as a boat dock with the boat stored on top of the floating platform and out of the water, such as a v-shape for accommodating a boat hull. The floating platform may be used as a staging area for tools and materials, or the floating platform may be used as a walkway, such as a catwalk. The floating platform may be formed in shapes other than a rectangular shape, and may not have a planar top surface.

The invention allows the floating platform 102 to be held in place relative to another object 104 without substantial horizontal movement of the floating platform. However, the floating platform according to the invention allows vertical movement of the floating platform relative to the object due to changes in water levels due to tides, weather, or wave action. The object may be in a fixed position relative to the earth or the object may be another floating object with floats 112. For example, the object could be a bulkhead fixed to the shore, or the object could be another floating platform or floating dock or the additional object could be a vessel, such as a ship or a boat. Whether the object is fixed or floating, the floating platform construct of the invention allows vertical movement of the floating platform relative to the object while holding the floating platform substantially in position horizontally, although the horizontal positioning may be adjusted.

At least two brackets 14 are mounted to the object 104. Each bracket has opposing members that allow the blade 110 of a guide to slidably engage the bracket between the opposing members. The blade 110 may be formed to a desired length, so that the floating platform 102 may be horizontally spaced from the object at a desired distance. With the blade being slidable within the brackets, this distance may be adjusted as desired by the user. After positioning the blades between the brackets, the horizontal distance of the floating platform to the object is adjusted and the blade is fixed to a position within the brackets such as by using a set screw to hold the blade and the guide post in a horizontal position relative to the object. The guide posts thereby hold the floating platform in a position relative to the object.

Guide posts 106 engage a cylinder 108 that extends above the blade 110. The blade, cylinder and bracket form a pile guide that limits horizontal movement of the guide posts and the floating platform 102 relative to the object 104. In this embodiment, the guide posts are fixed to blades 120 that slide relative to brackets 14 attached to the floating platform. The guide posts may be mounted to the blades 120 by a collar 116 that holds the guide post in position. The blades 120 may be formed to a desired length and positioned within the brackets so that the floating platform 102 may be horizontally spaced from the object at a desired distance, just as the object 104 may be spaced at a desired distance from the guide posts and floating platform through the use of the slidable blades 110. With the blades 120 being slidable within the brackets, this distance may be adjusted as desired by the user or installer. After positioning the blades between the brackets, the horizontal distance of the guide posts to the floating platform is adjusted and the blade is fixed to a position within the brackets, such as by using one or more set screws to hold the blade and the guide posts in the desired position.

In this embodiment the floating platform 102 is free to move vertically relative to the object 104 as the floating platform and/or the object floats in changing water levels. The fit of the guide posts 106 within the cylinder 108 is such that the guide posts, and therefore the floating platform, can move or slide vertically within the cylinder and move vertically relative to the object 104. The cylinder and the guide posts may be formed in other geometric shapes, and could be square in cross section for example, and long as relative movement is provided as described. The floating platform can move vertically independently of the object 104 to which the floating platform is attached. In this manner, if the object is fixed to the earth, changes in water levels do not submerge the floating platform. Similarly, if the floating platform is attached to a floating object, such as a large vessel, the floating object has less tendency to pull the floating platform under the water in the event of violent wave action.

The guide posts 106 may be formed to a length that is required by the application. For example, if the object 104 is fixed to the earth and the floating platform 102 is subject to two (2) meter tides, the guide posts may have a length of three (3) meters or more. In some applications it may be desirable to have a stop on the guide posts. The stop may be a pin inserted through a void of the guide post so that the floating platform does not disengage from the cylinder 108 in the event of an extremely low water level due to tides, wave action or other causes.

The guide posts 106 may have a round cross section, and form an elongated cylindrical shape. The cylinders 108 comprise voids having a complementary shape to the guide posts so that the floating platform moves vertically relative to the object 104 as water levels change. The guide posts and cylinders may have other complimentary shapes. The receptacles and guide posts are preferred to be formed of polyethylene, and particularly high density polyethylene, which is extremely durable, corrosion resistant, and has low friction qualities that facilitate the movement required by the objects of the invention. Low density polyethylene may be used in other applications.

In this embodiment, the guide posts are static piles 128 driven into the earth. The piles slidably engage pile guides 130 that are mounted to the floating member such as a floating dock and to pile guides 108 mounted to the object. In this embodiment the floating platform 102 moves vertically relative the piles 128 as the floating platform and/or the object floats in changing water levels. The fit of the piles within the pile guides is such that floating platform can move vertically relative to the fixed piles and move vertically relative to the object. The pile guides and the piles may be formed in desired geometric cross sections, and could be round or square in cross section for example, and long as relative movement is provided as described.

The guide posts slidably engage pile guides 108 that are mounted to the object. In this embodiment the floating platform moves vertically relative to the object as the floating platform and/or the object floats in changing water levels. The fit of the guide posts within the pile guides is such that floating platform can move vertically relative to the object 104. The pile guides and the guide posts may be formed in desired geometric cross sections, and could be round or square in cross section for example, and long as relative movement is provided as described.
