DETAILED DESCRIPTION

[0011] In relation to prior surface water de-icing devices, the present de-icing apparatus provides relatively small, portable, and adjustable devices for the specific purpose of de-icing a relatively small area of surface water for use by outdoor enthusiasts. The anchorable stand provides directional, surface height, and angular adjustment of the de-icing water flow to allow for establishing the preferred de-icing pattern at the water surface. De-icing means the reduction of freezing and the minimization of ice accumulation in a given surface area of the open body of water. The fixed-height vertical member of the anchorable stand provides a 360° adjustment range of output water flow. The adjustable-height vertical member of the anchorable stand provides surface height adjustment of the intake and output water flows. The vertical rotation point or points of the anchorable stand hold the water movement device and provide angular adjustment of the intake and output water flow.

[0012] FIG. 1 represents a de-icing apparatus 100 for de-icing a surface area of an open body of water. The de-icing apparatus 100 includes an anchorable stand 102 and a water movement device 160. The anchorable stand 102 includes a fixed-height vertical member 110, a cross bar 140, an adjustable-height vertical member 150, and may optionally include an anchoring cross-member 130 attached to the vertical member 110. The cross bar 140 attaches the fixed-height vertical member 110 to the adjustable-height vertical member 150.

[0013] The fixed-height vertical member 110 includes an anchoring member 112 having an anchoring end 135 that may be sunk into the mud, gravel, or other material forming the bottom of the open body of water to a depth to hold the water movement device 160 below, or preferably partially above and partially below the surface of the open body of water. The fixed-height vertical member 110 may include an anchoring cross member 130 attached above the anchoring end 135 of the anchoring member 112. The anchoring end 135 of the anchoring member 112 may be sunk in the bottom of the open body of water so the optional anchoring cross member 130 is in the bottom or on the surface of the bottom to further reduce the possibility that the anchoring member 112 will rotate during use of the de-icing apparatus 100.

[0014] The anchoring member 112 also includes a rotating member receiving end 137 having fixed attachment points 116. The fixed attachment points 116 may be provided by a disk 138 attached at the rotating member receiving end 137 of the anchoring member 112. The disk 138 is preferably circular in shape and substantially perpendicular to the longitudinal dimension of the anchoring member 112. However, the disk 138 could be square in shape and have additional orientations as long as the fixed attachment points 116 are provided. The fixed attachment points 116 may be provided by holes through the top and bottom surfaces of the disk 138. However, the fixed attachment points 116 may take forms other than holes, such as indentations in the top surface of the disk 138, spaces between protrusions from the anchoring member 112, and the like.

[0015] The fixed-height vertical member 110 also includes a rotating member 114. The rotating member 114 includes an outside dimension smaller than an inside dimension of the anchoring member 112. Preferably the outside dimension of the rotating member 114 and the inside dimension of the anchoring member 112 are diameters. The rotating member 114 slides inside of and is constrained in the downward vertical direction by the anchoring member 112. Preferably, the anchoring member 112 and the rotating member 114 are tubular in shape.

[0016] The rotating member 114 includes a rotating attachment point 118 to fix the rotational position of the rotating member 114. When the rotating attachment point 118 is aligned with one of the fixed attachment points 116, a first location holder 120 may be passed through the rotating attachment point 118 and through one of the fixed attachment points 116 to prevent rotation of the rotating member 114 about the anchoring member 112 of the fixed-height vertical member 110. The first location holder 120 may take the form of a smooth pin (not shown), a threaded bolt with a nut, and the like to prevent rotational movement of the rotating member 114 about the anchoring member 112.

[0017] The rotating member 114 may include an angular support 142 attached to the cross bar 140 that provides additional mechanical support to maintain attachment of the rotating member 114 to the cross bar 140 and to assist in maintaining the substantially horizontal orientation of the cross bar 140 during use of the de-icing apparatus 100.

[0018] The adjustable-height vertical member 150 includes a fixed receiver 144 having at least one vertically-fixed attachment point 146 to the cross bar 140 and a movable rod 152 including multiple vertically-movable attachment points 154. The movable rod 152 is configured to pass through the fixed receiver 144. As rotation of the movable rod 152 in relation to the fixed receiver 144 is undesirable, the movable rod 152 and the fixed receiver 144 may be shaped to prevent rotation. Thus they may be square, rectangular, triangular, star-shaped and the like so that when the movable rod 152 is passed though the fixed receiver 144, the movable rod is impinged in the rotational direction. The movable rod 152 and the fixed receiver 144 are preferably hollow in the longitudinal direction, but the movable rod 152 may be solid.

[0019] The at least one vertically-fixed attachment point 146 may be provided by a hole through the fixed receiver 144 that may be aligned with one of the vertically-movable attachment points 154. If more than one vertically-fixed attachment point 146 is used, then multiple holes through the fixed receiver 144 may be aligned with more than one of the vertically-movable attachment points 154. The vertically-movable attachment points 154 may be provided my multiple holes through the movable rod 152. Although less preferred, the vertically-fixed attachment point 146 could have the shape of a “U”, thus allowing alignment with one of the vertically-movable attachment points 154.

[0020] When the at least one vertically-fixed attachment point 146 is aligned with one of the vertically-movable attachment points 154, a second location holder 122 may be passed through the at least one vertically-fixed attachment point 146 and through one of the vertically-movable attachment points 154 to prevent vertical movement of the movable rod 152 in relation to the fixed receiver 144. The second location holder 122 may take the form of a smooth pin, a threaded bolt with a nut (not shown), and the like to prevent vertical movement of the movable rod 152 in relation to the fixed receiver 144. If the vertically-fixed attachment point 146 was in the shape of a “U” as opposed to a “hole”, then upward vertical movement of the movable rod 152 could occur while downward movement of the movable rod 152 in relation to the fixed receiver 144 would be stopped. Optionally, additional location holders may be used. The second location holder 122 also may operate to prevent rotation of the movable rod 152 in relation to the fixed receiver 144, in the event the movable rod 152 and the fixed receiver 144 are not shaped to prevent rotation.

[0021] FIG. 2A represents a housing-tilting version 260 of the water movement device 160. The housing-tiling water movement device 260 attaches to the movable rod 152 by a fork-arm 156 attached to a lower end of the movable rod 152. The fork-arm 156 includes a first arm 157 that terminates in a first vertical rotation point 157A and a second arm 158 that terminates in a second vertical rotation point 158A. The vertical rotation points 157A, 158A may be in the form of holes through the first and second arms 157, 158 and through opposing sides of housing 168. The water movement device 160 is attached to the first and second arms 157, 158 at the first and second vertical rotation points 157A, 158A. Bolts, rivets, pins and the like may be passed through the arms 157, 158 and through the housing 168 to form the vertical rotation points 157A, 158A. Other mechanical attachments that provide for vertical rotation of housing 168 may be used.

[0022] When propeller 210 driven by an electric motor internal to the housing 168 rotates, water moves from intake 162 to outlet 166 of the housing 168. Optional housing vents 164 may be present behind and/or in front of the propeller 210 to provide additional intake or output of water, respectively. In this way, water is circulated though the housing 168 to maintain a defrosted surface area of the open body of water.

[0023] FIG. 2B represents a motor-tilting version 280 of the water movement device 160. The motor-tilting water movement device 280 attaches to the lower end of the movable rod 152 by a vertical rotation point 258 formed from a hole through the movable rod 152 and an aligning hole in an attachment member 256 that is attached to a diameter contracting member 282. The attachment member 256 may be a bracket having a general “U” shape and configured to be slightly wider than the movable rod 152. The diameter of the diameter contracting member 282 may be increased or decreased to hold drive motor 215 when tensioner 284 is adjusted. The tensioner 284 may be a threaded bolt or other device that increases or decreases the diameter of the diameter contracting member 282 in response to mechanical movement of one or more parts.

[0024] When propeller 212 is driven by the drive motor 215, water moves from intake area 262 to outlet area 266. Protective cage 288 prevents large debris, aquatic life, and other waterborne species from damaging the propeller 212. In this way, water is circulated though the protective cage 288 to maintain a defrosted surface area of the open body of water.

[0025] FIG. 3 represents the de-icing apparatus 100 during de-icing a surface area 330 having ice 335 of an open body of water 320. The de-icing apparatus 100 is driven into lake bottom 310 and is held by the anchoring end 135. The de-icing apparatus 100 may be further held in the lake bottom 310 by the optional anchoring cross member 130. In use, the drive motor is electrically energized to move water from an inlet or inlet area to an outlet or outlet area of the water movement device 160. In FIG. 3 the water movement device 160 is represented by the housing-tilting version 260, however the motor-tilting version 280 also may be used. The vertical rotation point or points of the de-icing apparatus 100 allow for tilting of the water movement device 160 without placing a hand in the water to alter the de-icing water flow to provide the desired de-icing pattern of the surface water.

[0026] While various embodiments of the invention are described, it will be apparent to those of ordinary skill in the art that other embodiments and implementations are possible within the scope of the invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents.
