sum 2 Bf 2 7 awvz v5 BACKGROUND OF THE INVENTION This invention relates to a novel mooring device for floating equipment which device is especially useful on variable waters.

Man-made lakes provide much of this country with the only available water recreation. However, many of these man-made lakes were constructed specifically for flood control. Therefore, the water level in these lakes usually fluctuates widely from spring to fall.

Conventional docks and boat hoists which are anchored to the bottom of these lakes must be moved periodically to be useful to the owners thereof. Even floating docks must be moved inwardly or outwardly as the waters rise and fall. Methods and equipment for moving docks and boat hoists of these types, as well as FIG. 6 illustrates the placement of the chains and, additionally, illustrates how the floating dock can be moved relative to the shore line.

FIG. 7 is a plan view illustrating the placement of the chains and, in phantom, indicating the relative movement of the boat hoist as the waters in a lake flucuate.

FIG. 8 is a side view of the boat hoist with the walkway in a lowered position.

most floating equipment 19 such as floating docks,

therethrough and guide means 14. aligned with the first means 12 and spaced apart therefrom. Means 16 are provided for releasing the chains 13 secured in the first means 12; said means 16 being operable from the shore 17. The chains 13 are securable at their respective ends to the shore 17 and the bottom 18 of the body of water.

More specifically, the device 11 of this invention is utilized to selectively moor floating equipment 19. The chains 13 each pass through a first means 12 and a guide means 14 and are anchored, at their

respective ends

21 and 22, to the shore l7 and the bottom 18 of the lake. When the water level fluctuates, the floating equipment 19 can be moved readily by releasing the first means 12 and moving the equipment l9inwardly or outwardly with a gentle push or pull. The chains 13 remain secured at their

respective ends

21 and 22 during this moving operation.

The device 11 of this invention can be utilized with floating boat and/or plane hoists, diving rafts etc. Specifically shown in FIG. 1 is a floating boat hoist 23. The boat hoist 23 comprises a U-shaped platform 24 supported on styrofoam or the like floatation blocks 26. A hoist mechanism 27 is suspended between the

legs

28 and 29 of the U-shaped platform 24 and is utilplatform 24, the struts 33 being positioned proximate the outside edges of the

legs

28 and 29 of the U-shaped platform 24. By supporting the weight of the hoist mechanism 27 and the boat supported thereby on the outside of the platform, stability is built into the boat hoist 23.

A first means 12 (FIGS. 1 and 7) is mounted on each of two opposing sides 34 and 36 of the floating equipment 19. Preferably, the opposing sides 34 and 36 are those sides designed to be substantially perpendicular of the shore. As shown in FIG. 1, the first means 12 are advantageously secured near the bottom of the struts 33 on opposing sides 34 and 36 of the boat hoist 23.

The first means 12 (FIGS. 3-5) are each comprised of a securement means 37 and an alignment means 38. The securement means 37 is generally formed from a flat sheet 39 or bar of metal or the like secured perpendicularly of the

legs

28 and 29 of the platform 24. The

bar 39 has a keyhole slot 41 formed therethrough, preferably in an inverted position as shown in FIG. 5. The narrow portion 42 of the keyhole slot 41 has a width slightly wider than the depth (indicated at A in FIGS. 3-4) of a single link 43 of the chain 13. The width of the narrow portion 42 is, however, narrower than the width (indicated-at B in FIGS. 3-4) of a link 43. Therefore, when a link 43 is retained in the narrow portion 42 of the keyhole slot 41, the adjacent link 43 abuts the bar 39 thereby holding the chain 13 and the first means 12 in rigid engagement.

The wide portion 47 of the keyhole slot 41 is slightly wider than the width B of a link 43 of the chain 13. Preferably, the wide portion 47 is of a circular configuration as shown best in FIG. 5.

The bar 39 is suspended between the aligning members 44 and 46 (FIGS. 3-5). A rod 48 is rigidly secured as by welding to the upper portion of the bar 39. The upper end 49 of the rod 48 terminates in a hook 51 (FIG. 1). The bar 39 can be raised vertically by pulling upwardly on the hook 51. In the raised position, the wide portion 47 of the keyhole slot 41 is aligned with the aligning

members

44 and 46 and the chain 13 can pass freely through the slot 41. The bar 39 is, however, normally in the lowered position wherein the narrow portion 42 of slot 41 is aligned with the aligning

members

44 and 46. The bar 39 is forced into this position by the weight of this bar 39 and preferably is aided by a coil spring or the like (not shown). The bar 39 is held in position horizontally by the chain 13.

The aligning

members

44 and 46 are rigidly mounted on opposing sides 34 and 36 of the boat hoist 23 with the bar 39 suspended therebetween. The aligning

members

44 and 46 are substantially parallel of the opposing sides (FIGS. 1-5) 34 and 36 of the boat hoist 23 and are normally aligned with the narrow portion 42 of the keyhole slot 41. Each of the aligning

members

44 and 46 is hollow and of substantially frustoconical configuration. The smaller openings 52 face each other through the keyhole slot 41.

The guide means 14 also generally comprise a pair of hollow frustoconical aligning members 53 and 54. These aligning members 53 and 54 are secured to opposing sides 34 and 36 of the boat hoist 23 and are aligned with the first means 12. The aligning members 53 and 54 can be spaced apart as shown in FIG. 2 or they can abut each other thereby forming a single unit (not shown).

The guide means 14 and the first means 12 are spaced apart as shown in FIG. 1 and are aligned with each other. With the chains 13 in place in the first means 12, the chains 13 parallel the sides 34 and 36 of the boat hoist 23.

The chains 13 are disposed on opposing sides 34 and 36 of the boat hoist 23; each of the chains extends through a first means 12 and a guide means 14. The ends 21 and 22 of the chains 13 are secured, respectively, to the shore 17 and the bottom of the lake. As shown best in FIG. 7, the portions 56 of the chain 13 between the shore 17 and the guide means 14 form acute angles (indicated at C) with the sides 34 and 36 of the boat hoist 23 carrying the guide means 14 and the first means 12, those sides 34 and 36 being generally perpendicular of the shore 17. The portions 57 of the chain 13 between the first means 12 and the other ends 22 of the chain 13 also preferably form acute angles (indicated at D) with the sides 34 and 36 of the boat hoist 23.

The chains 13 can be anchored to the bottom 18 of the lake with cement blocks 58 (FIGS. 6 and 7) or the like. The anchors formed in thismanner should weight between 300 and 1,200 pounds. The chains 13 can be anchored to the shore 17 in any convenient manner.

Rubber snubbers 59 (FIG. 7) can advantageously surround several links 43 of the chain 13 to absorb shock in the chains 13 on rough waters. These snubbers 59 also absorb some of the shock when there is excessive movement on the platform 24.

The means 16 operable from the shore 17 for releasing the chain 13 in the first means 12 is shown in FIG. 1. This means 16 comprises a first pulley 61 disposed above each of the securement means 37, and more specifically, directly above the upper end 49 of the rod 48. The pulley 61 is rotatably secured to the boat hoist 23. Second pulleys 62 are rotatably secured proximate the forward end 63 of the boat hoist 23. More than one second pulley 62 canbe utilized if the floating equipment 19 is excessively large. Two

lines

64 and 66 are provided, each of the

lines

64 and 66 being secured at one end 67 to the upper end 49 of the rod 48. The

lines

64 and 66 travel over a first pulley 61 anda second pulley 62 and are secured, at the other end 68; proximate the shore 17. As shown in FIG. 1, posts 69 and 71 can be constructed at the end of the walkway 72 for securing the

lines

64 and 66 thereto.

Conventional walkways (not shown) can be utilized with the boat hoist shown in FIG. 1. However, on variable waters, conventional walkways must be resecured to the bank each time that the boat hoist 23 is moved.

Accordingly, a novel walkway 72 (FIGS. 1 and 8) has been designed. This walkway 72 comprises a deck surface 73 formed in two sections 74 and 76. These sections 74 and 76 are hingeably secured together and the section 76 adjacent the boat hoist 23 is rotatably secured thereto at the forward end 63 of the boat hoist 23. Means 77 are provided for rotating one section 74 relative to the second section 76 and securing that section 74 in place. The means 77 can comprise a line 78 secured between opposite ends 79 and 80 of the walkway 72. The line 78 passes through a retainer 81 disposed above the hinged joint between the deck sections 74 and 76. The forward section 74 can thereby be raised and secured in place. By utilizing this hinged walkway 72,, the walkway 72 can be utilized with the steep banks found on many man-made lakes or the floatation member 82 is designed to maintain the forward end of the walkway 72 above the bank when the walkway 72 is carrying no load. When the walkway 72 is loaded (FIG. 8) the floatation member 82 allows the walkway 72 to touch the bank.

OPERATION When placing the boat hoist 23 in the water for the first time, the chains 13 are first threaded through the guide means 14 and the first means 12. The ends 21 of the chains 13 are secured to the shore 17 above the high water line and spaced outwardly of the boat hoist 23. The other ends 22 of the chains 13 are weighted with cement blocks 58 and secured to the bottom 18 of the lake below the low water line. By releasing the first means 12, the boat hoist 23 can be placed at any desired position. 1
