Description
~222166 ~ -F`IELD OF THE INVENTION ,~
This invention relates to a modular type floating dock and, more specifically, to an interlocking assembly for the floatation units of the dock.
BACKGROUND OF THE IN~NTION
Canadian Patent No. 982,881 da.ed February 3, 1976 to H. Stanzinger (corresponding U.S. Patent No. 3,824,~44 dated July 23, 1974) discloses floating docks made of a plu-rality of interlocking units. The interlocking means thereof consist of pins engaging through superposed eye lugs. The conical enlarged heads of the pins have two projections which come into éngagement with rounded grooves in the corners of the floating units so as to thus resiliently lock the pin against inadvertent rise out of the eye lugs. Since these pins are resiliently held in locking position, they may - eventually become disengaged from the eye lugs in wavy waters. If conventional bolts and nuts were used, a swimmer would need to crawl under the floating dock to hold the nut in position when a second person would screw the bolt from above. This is obviously inconvenient.
OBJECTS OF T~ INVENTION
The general object of the invention is to provide an interlocking bolt and nut arrangement ~or modular~floating`
dock units with means to hold the locking ~ut i~p~s=itlon -below the dock to prevent its rotation when screwing the bolt from above. An important object of the present inven-tion is to prevent release of the interlocking arrangement by wave action. Another object of the invention is to provide the above mentioned arrangement for attaching bumpers, cleats and the like to the sides of the dock.
1222i66 SUMMARY OF THE INVENTION ,~
The interlocking assembly of the invention com-prises eye lugs projecting from the corners of the floating units at different levels so that they may be supérposed when, for instance, f.our floating units are joined together, a bolt with an enlarged head and a th-ea~eQ. spindle is inser~ed from above through the sùperposed eye lu~s and screwed into a nut underlying the lowermost lug.
In accordance with the invention, nut holding anti-rotation means hold the nut in positian and prevents its rotation when the bolt is screwed into the nut.
The enlarged conical shape of the head comes into frictional engdgeme~lt with matching frusto-conical corner surfaces of the floating units and thus positively prevent inadvertent unscrewing of the bolt.
The same lugs are used to attach bumpers and cleats to the sides of the dock. These bumpers and cleats are formed by changing the shape of the above-noted bolt head.
The nut holding and anti-rotation means include a pair of upstanding parallel flanges of ~-shape cross-section and protruding from one end face of the nut and slidably engageable into si~e grooves fonmed at the.t~p surface of the lowermost lug of each floating u~it, - -Anti-rotation means are also provided to prevent rotation of the bumpers or cleats when screwed in position by means of a conventional nut, these second anti-rotation means includes r.idges formed on~the stem of the bumpers and cleats and engageable witl corresponding notches formed at the periphery of the eye of the lugs.

DETAILED DESCRIPTION OF THE DRAWINGS
We will first refer to Figs. ~l and 2 ~of Athe drawings.
The floating dock 20 is constituted of a plurality of similar floating units 22. Each floating unit 22 is of polygonal shape and, preferably~ square section in which case it comp-ises four diagonally extending corner eye lugs 24 set at four different levels from the top surface 25 of each unit, each having having four circumferentially spaced not-ches 28 for a purpose later set forth.
l~ZZ16~ `
Each floating unit 22 is water-proo~ and prefer-ably hollow and may be moulded out of synthetic resins such as high densily polyethylene. A plastic foam may fill each unit 22. Each top corner of each unit 22 forms a concave and inclined frusto-conical surface 30 which is followed by a partly-cylindrical surface portion 32, in turn followed by a flat suxface 34 from which horizontally extends a lug 24. Surface 34 is set at 45 from the ad~oining side surfaces of the units so that, in practice, each lug 24 extends diagonally of the floating unit 22. The lowermost lug 24a is provided with longitudinally extending and parallel lateral grooves 36 formed at the top of the lug.
A bolt 38 and a corresponding nut 40 are provided. Bolt 38 is preferably also made of synthetic resin and is hollow and has a generally frusto-conical head 42 adapted to match and fit on the concave frusto-conical surface portion 30 of the four adjacent units 22 interconnected by the bolt 38.
Depending from head 42 is a hollow spindle 44 which has external threads 46 at the lower portion thereof. Spindle 44 is long enough to extend past through the superposed four lugs and past the lowermost lug 24a. The nut 40 is of standard construction but is characterized by an integral ring 48 at one end face thereof, said ring 48 forming a pair of diametrically opposite and parallel upstanding flanges 50 of L-shape cross-section defining guide slots 52. The thickness of the internal top portion 54 of the flanges 50 is at the most equal to the depth of the grooves 36 of the lowermost eye lug 24A. Nut 40 is first slipped in posi-tion on the lowermost lug 24A with the top parts 54 of the flanges 50 engaging the respective grooves 36 of the ll!~g 24A. The sliding arrangement has prefexahly a friction fit so that the nut may be held in register with-the eye 26 of the lug 24A. Then it is a simple matter to assemble four adjacent floating units 22 with~ four eye lugs in superposed position as shown in Figure 3 and then to insert from above the bolt 38 and screw said bolt within the nut 40 which is not only held in position underneath the dock but is also held against rotation during screwing of the bolt. Screwing of the bolt is achieved with a suitab~e tool engaging the spaced holes 56 formed at the top surface of the bolt head 1~ 42 because the top parts 54 of the flanges 50 do not protrude above thé top surface of the lowermost lug but are pre`ferably flush wi~h the same, th,e, lowermost lug with the nut forms a full size surface for resisting the downward pressure of the remaining lugs when a load rests on the units associated with the lugs 24.
The floating units 22 may be assembled to form a dock of any s~ze and/or shape. The exposed sides of t.he assembled units have exposed lugs 24 ~r 24A which may be used to att,~h bumpers and/or cleats as shown at 58 ~!nd 60 respectively. These bumpers and cleats are adapted to be secured either to one lug at a corner of the dock or to two superposed lugs 24, or 24 and 24A at the junction of two adjacent floating units 22 by means of standard nuts 62. The bumPers and cleats are of a hollqw,~onst~uction and mouldeà of s~nthetic resin bùt the bumpers'~58 havè a somewhat flexible wall and are designed to be filled with gas under pressure through a one-way valve 64 of conven-tional construction located at the bottom end of the bumper.
Bumper 58 has an enlarged head 66 and a co-axial pin or spindle 72. One half portion of the head 66 is of generally frusto conical shape as shown at 67 downwardly 12221~i6 followed by a cylindrical half portion 68. Portio~s 67 and 68 of the bumper are adapted to fit the correspond-ing surface portio~.s 30 and 32 at the corners of tw~
adjacent floating units 22. The other half portion.of the head 66, indicated at 70, is of generally half-cyl-indrical shape, having a diameter corresponding to the maximum diameter of the head 66. `This cylindrical half portion 70 is adapted to protrude from the side edge of the dock. The bumper has a spindle 72, the top portion of which is provided with longitudinal equally, radially-spaced rldges 74, adapted to have a sliding fit with the notches 28 of the eye 26 of anyone of the lugs 24 and 24A.
The lower portion of the spindle 72 is threaded, as shown a~:
at 76, to be screwed within the nut 62. A one-way valve 74 ~is f.itted within the free end of the spindle 72. The bumper,once inserted through one or two lugs at a corner of the dock or along the sides of the dock, is held against rotation by the ridses 74 which engage the notches 28 and, therefore, it is a simple matter to screw the nut 62 . by means of a suitable tool, such as a wrench, because these nuts are accessible along the sides of the dock.
The cleats 60 have a head 78 in the form of a cleat with a lower cylindrical wall 80 adapted to fit against the cylindrical surface portions 32 at the corners of the floating units 22. A cleat is further provided with a spindle 72, ridges 74 and threaded portion 76, as for the bumpers S8 and is therefore secured to one lug in the same manner as the bumper 58.
