Abstract

A floating dock is formed from a fabricated frame including a pair of longitudinal extruded side rails and a plurality of cross rails interconnecting the side rails to form a rigid generally rectangular structure arranged to receive buoyancy members for floating the frame on a body of water. A plurality of floor planks bridge the side rails for forming a floor surface on the frame to be supported above the water. The rails include grooves in each surface defining a fastener having a nut to be located in the groove and a co-operating male fastener for engaging into the nut. The outer surface fastens to a rail along the outer surface and the inner surface carries the ends of the floor planks and attaches to fastening brackets of corner members.

Claims

1. A floating dock comprising:

a fabricated frame including a pair of longitudinal side rails and a plurality of cross rails interconnecting the side rails to form a rigid generally rectangular structure;

the frame being arranged to receive one of more buoyancy members for floating the frame on a body of water;

a plurality of floor planks for forming a floor surface on the frame to be supported above the water;

each of the side rails being formed of an extruded member;

wherein each of the side rails is generally rectangular in cross section with an outwardly facing upstanding surface, an inwardly facing upstanding surface, a top surface and a bottom surface;

wherein the outwardly facing upstanding surface of each respective one of the side rails has a channel within which an elongate member can be received and fastened to the respective one of the side rails by a plurality of fasteners at spaced positions along the respective one of the side rails;

wherein the outwardly facing upstanding surface includes a mounting groove within the channel for receiving said plurality of fasteners which engage into the mounting groove at spaced positions along the length thereof.

2. The floating dock according to claim 1 wherein the channel includes upper and lower receptacles defined by edge flanges at the outwardly facing upstanding surface.

3. The floating dock according to claim 1 wherein each of the side rails includes in the top surface and bottom surface a respective mounting groove arranged to receive a nut of a fastening system for attachment to a male fastener.

4. The floating dock according to claim 3 wherein the inwardly facing upstanding surface also includes at least one mounting groove.

5. The floating dock according to claim 3 wherein the inwardly facing upstanding surface has two vertically spaced mounting grooves for attachment to connecting brackets.

6. The floating dock according to claim 3 wherein the inwardly facing upstanding surface includes a channel for receiving ends of the floor planks.

7. The floating dock according to claim 3 wherein the inwardly facing upstanding surface includes an upper receptacle for receiving ends of the floor planks and at least one lower mounting groove arranged to receive a nut of a fastening system for attachment to a male fastener of an attachment bracket.

8. The floating dock according to claim 1 wherein each of the mounting grooves has a mouth located in the respective surface of the side rail and a receptacle portion behind the mouth, the receptacle portion being wider in a direction transverse to the longitudinal direction than the mouth so as to define two shoulders of the front wall each on a respective side of the mouth;

wherein each fastener comprises a nut member having a female threaded hole therein, the nut member being shaped and arranged to be located in the respective groove;

each nut member having a width in the direction transverse to the longitudinal direction greater than the width of the mouth so as to define two front bearing surfaces on a front surface of the nut member each on a respective side of the hole for engaging a respective one of the shoulders,

the female threaded hole being located between the bearing surfaces and arranged in an operating position of the nut member with an axis of the hole at a right angle to the front wall of the mounting body containing the mouth;

and wherein each fastener comprises a fastener member having a male thread thereon shaped and arranged to pass through the mouth and to engage the female threaded hole in the nut member so as to pull the bearing surfaces of the nut member against the shoulders;

each nut member being shaped such that it has a width in a direction longitudinal of the axis of the female threaded hole which is less than the width of the mouth so that the nut member can be inserted into the groove through the mouth with the nut member turned around an axis parallel to the longitudinal direction through ninety degrees from its operating position so that the axis of the female threaded hole is parallel to the front face of the front surface of the mounting body and so that the nut member can be rotated in the receptacle portion around the axis parallel to the longitudinal direction through ninety degrees to turn the female threaded hole back to the operating position of the nut member;

each receptacle portion having a base opposite the mouth which is smoothly curved about an axis parallel to the longitudinal direction;

each nut member having a rear face which faces the base of the receptacle portion in the operating position of the nut member which is smoothly curved about an axis parallel to the longitudinal direction and which matches the smooth curvature of the base of the receptacle;

each receptacle portion having two each sides extending from the base to the front wall at a respective one of the shoulders which are parallel and substantially tangential to the base;

wherein a depth of each groove from the front wall to the base is greater than a width of the respective nut member between the front surface and the rear surface of the nut member in a direction at a right angle to the front surface.

9. The floating dock according to claim 8 wherein the base of each groove and the rear surface of the respective nut member are both semi-cylindrical.

10. The floating dock according to claim 8 wherein each nut member includes a pair of elements each element being arranged along or adjacent a respective side edge of the front face of the nut member and arranged to engage with a respective element along a respective one of the shoulders so as to resist outward movement of the shoulders.

11. The floating dock according to claim 10 wherein one of the elements comprises a rib and the other a groove.

12. The floating dock according to claim 11 wherein the element on the nut comprises a rib and the element on the shoulder comprises a groove.

13. The floating dock according to claim 12 wherein the rib and the groove each taper to an apex.

14. The floating dock according to claim 8 wherein the nut member includes a pair of grooves with one along a center line of the front face and the second along a center line of the rear face.
