Description
The present invention is directèd to dock structures.
Dock structures, particularly floating or standing docks for pleasure craft, conventionally are formed of wood and include a plurality of transversely-extending slats joined to depending parallel side rails and possibly one or more intermediate rails, depending on the wîdth of the dock. The depending side rails are joined to one or more floats, in the case of a floating dock, or to pillars or uprights anchored on the river or lake bed in the case of a standing dock. End rails extending between the side rails also may be provided.
Wooden structures suffer from many disadvantages.
In regions where the water body in which the dock is located freezes during the winter months, the dock must be removed from the water to prevent ice damage. Wooden structures are heavy, especially when waterlogged, making removal from the water a difficult operatîon, especially since the structure must he-removed as a single unit.
Wooden structures also degrade rapidly under the exposure to weather and traffic and require replace-ment from time to time. Broken slats are difficult to replace effectively and to dispose of.
In accordance with the present invention, there is provided a dock structure which does not suffer the drawbacks of the prior art structures. The dock structure of this invention has the main structural parts formed of aluminum. The deck members are releasably connected to

In accordance with the present invention, there is provided a dock structure which does not suffer the drawbacks of the prior art structures. The dock structure of this invention has the main structural parts formed of aluminum. The deck members are releasably connected to
- 2 -~70~713 parallel elongate side rails connected -to aluminum end rails, and an aluminum bumper rail having a bumper bar is releasably connected to the side rails. The structure is lightweight, virtually indestructible and may be readily assembled and readily disassembled for removal and stoxage.

Referring to the drawings, a dock s-tructure 10 comprises a plurality of generally parallel deck members 12 ~, . ., ~
: ' ' ' ~ '" ' ' ' ' ' ' ' ~1~7~78 constructed of aluminum releasably connected to a pair of parallel aluminum side rail members 14 extending generally perpendicularly to the decX members 12.
Aluminum end rail members 16 extend between and generally perpendicular to the ends of the side rail members 14 and are connected thereto.
The dock frame 17 is completed by an aluminum rail member 18 extending between and connected to the side rail members 14 at the approximate midpoint along their length. In the frame structure of Figure 8, additional aluminum rails 20 extend parallel to the side rails 14 and are connected between one end rail 16 and the centre rail 18 to provide strength and rigidity to the frame 17. In dock frames 17 of lesser width, as shown in Figure 10, the additional rails 20 may be omitted.
The dock frame 17 comprised of the rail members is rigid and is attached to one or more floats 22. The floats may be of any convenient form, for e~ample, hollow plastic floats. If the dock 10 is a standing structure, the frame 17 is connected to pillars or ground anchors.
The invention will be described particularly with reference to a flaati~g dock structure.
Each side rail mem~er 14 has a generally E-shaped cross-section opening outwardly of the dock frame 17 and each end rail member:l6 is of generally flat-based C-shaped cross-section opening inwardly of the doc~ frame 17, Adjacent ends of the side rail members and the end rails 16 are rigid-ly joined by angle plates 24 which are ~olted to both the side rai] 1~ and the end rail 16 by 3Q bolts 26.
The centre rail 18 and the additional rails 20, -1~3'7U3~'78 if any, are also of flat-based C-shaped cross-section, but the upper and lower projections of the additional rails 20 are cut away adjacent their ends to allow for entry into the C-shaped cross-section of the end rails 16 and centre r.ail. 18.
The centre rail 18 is connected at its ends to the side rails 14 by angle plates 26 which are bolted to both the side rail 14 and the centre rail 18. The additional rails 20 are connected to the end rails 16 by angle plates 28 which are bolted to both the rails 16 and 20 and to centre rail 18 by angle plates 30 which are bolted .
to both the rails 18 and 20.
OnLy one of the additional rails 20 need have the upper and lower projections cut away at both ends, while the other need have the projections cut`away at the end connected to the end rail 16, since this rail 20 does not project into the opening of the centre rail 18.
However, for ease of manufacture and assembly, it is preferred to have both additional rails 20 identically constructed, as illustrated.
The aluminum rail members 14, 16, 18 and 20 may b~ conveniently formed by extrusion, although any desired manufacturing technique may be adopted.
Each end rail 16 has a bumper bar 32 connected thereto in any convenient manner. Usually the bumper bar 32 is of rectangular of square cross-section and con-struct~d of wood, but any other convenient constructiQnal material may be used.
Each side raii mem~er 14 has a vertically-extending we~ 34 and three integrally-formed projections 36, 38 and 40 therefrom. The projection 36 extends r-- .
1~7~ 8 horizontally from the lower end of the web 34 and engages the upper surEace of the float 22.
The projection 38 is L-shaped and forms an upwardly-opening channel 42 with the web 34. The projection 40 includes a horizontally-extending portion 44 and an upwardly-opening channel-defining portion 46 at the end of the portion 44 remote from the web 34. The purpose of the channels 42 and 46 will become apparent hereinafter.
The horizontally-extending portion 44 has a plurality of upwardly-extending integrally formed laterally-thin and longitudinally-extending protrusions 48 equally spaced along the length of eacb side rail member 14 and equal in number to the number of the deck members 12.
Each of the protrusions 48 is undercut at its ends to define therein shoulders 50 and 52 respectively and undercuts S4 and 56 respectively. While the structure is illustrated with one protrusion 48 at each end for each deck mem~er 12, a plurality of such protrusions 48 may be provided for each deck member 12, for greater strength or rigidity.
Each deck member 12 has a continuous planar surface 58, preferably provided with a non-slip outer surface, which cooperates with other like surfaces to form a planar deck surface to the dock 10. Integral skirt portions 60 and 62 depend from adjacent the lateral sides of the planar surface 58 generally perpendicularly thereto.
At the lower end of each skirt portion 60 and 62 is a shoulder-engaging mem~er 64 and 66 respectively.
Each shoulder-engaying member includes a portion projecting inwaxdly of ~he skirt 60 or 62 towards the other and a shoulder Eace-engaging portion. ~enerally, the shoulder-~L~7~
engaging member 64 projects inwardly a greater distance than the shoulder-engaging member 66 and a distance substantially e~ual to the depth of the undercut 54.
While the undercuts 54 and 56 have the dimensions and depth approximately equal to the extremitv of the shoulder-engaging member 64, this arrangement is for convenience in assembly of the dock 10, allowing the longer shoulder-engaging member 64 to be inserted in either undercut 54 and 56 to engage both the shoulder and end wall of the undercut, so that the arrangement shown in Figures 4 and 5 with respect to the relative positions of the shoulder-engaging members 64 and 66, may be attained.
Ho~everl if desired, the undercuts 54 and 56 may be dimensioned such that the undercut 54 has a depth at least equal to the maximum distance of extension of the shoulder-engaging member 64 and the undercut 56 has a lesser -depth at least equal to the maximum distance of extension of the shoulder-engaging member 66.
Each shoulder 50 and 52 has a sloping outer surface 68 while the surface of the shoulder-engaging member 66 intended to engage the sloping surfaces 58 during assembly, as described below, is bevelled at 70.
The deck mem~ers 12 also include a pair of webs 72 depending from the planar surface 58 parall~l to the skirt portions 60 and 62 for engagement with the horizontally-extending portion 44. A single such web 72 may be used, if desixed, although it is preferred to provide the pair of such webs for strength and stability. Greater numbers of such webs 72 may be used, if desired.
Slots 74 are provided in each of the webs 72 for receiving the protrusion 48 therein. The interaction of the protrusion 48 with the slots 74 constitutes stop means and prevent longitudinal displacement of the deck members 12 relative to the side rails 14 in an assembled dockO In this way, a stable assembly is achieved.
Each deck member 12 has a thickness and size allowing limited flexibility when bent along along its longitudinal centre line. This flexibility, the dimensioning of the deck members 12, the dimensioning and shape of the protrusions 48 and the dimensioning o~ the shoulder-engaging members 64 and 66 combine to provide snap-fit means, read~ly releasably interlocking the deck mem~ers 12 to the side rails 14. The interlocking and releasing of the deck members 12 and side rai~s 14 is achievable without the use of special tools or skills.
As seen particularly in Figures 3 to 5, the deck members 12 are assembled with the side rails 14 at each intersection thereof by inserting the longer shoulder-engaging member 64 into the undercut 54 and pushing the shorter shoulder-engaging member 66 against the upper and outer surface of the shoulder 52, causing the deck member 12 to flex slightly about its centre line, thereby moving the shoulder-engaging members 64 and 66 a greater distance apart, so that the bevelled suxface 70 of the shoulder-engaging member 66 rides on and round.the surface 68 of shoulder 52 and snap fits into the undercut 56 in engagement with the underside of the shoulder 52. At the same time, the protrusions 18 extend into the slots 74.
Disassembly of the interlock is readily achieved ~y ~lexing the mem~er 12 about its centre line unt;l the shoulder-engaging members 6~ and 66 are spaced ~7Q~7~3 apart a distance su~ficient to remove the shoulder-engaging member 66 ~rom the undercut 56.
The disassembly of the deck members 12 and side rails 14 is not prevented by the stop means constituted by the interaction of the protrusion 48 with slots 74.
If desired, the additional rails 20 may be provided with one or more protrusions 48 with the webs 72 being provided with appropriate slots 74 for releasable interconnection of the deck members 12 to the additional rails 20 at their intersections to increase the rigidity and strength of the overall structure.
Additionally, while the protrusions 48 are shown as a single integral member, the protrusions may be formed in discontinuous mannerl typically having three separate parts, one at each end having the undercuts therein and a central tab for projection into the slot 74.
The dock 10 also is provided with a pair of side bumper rails 76 releasably connected one to each side rail 14. Each bumper rail 76 comprises an elongate aluminum member 78, which generally is formed by extrusion having a generally E-shaped cross-section opening towards the side rail 14 and a generally ~lat-based C-shaped cross-section opening away from the side rail 14. A bumper bar 80 of any convenient material, such as wood, plastic or rubber, havi~g a suitable cross-section, such as the gen-erally rectangular or square cross section illustrated or a part-circular cross-section, is received in the U-shaped cross-section opening of the elongate member 78 and secured therein, such as, by securing screws 82.
The elongate mem~er 78 includes a vertically-extending web 84 and integrally-~ormed projections 86, 88 and 90. The projection 86 extends horizontally on both _ g _ sides of the web 84 perpendicularly thereto. The projection 88 extends horizontally on both sides of the web 84 perpendicularly thereto and also includes a depending skirt portion 92 at the end of the projection 88 remote from the web 84 and closest to the side rail 14.
Theprojection 90 is L-shaped and forms a downwardly-opening channel 94 with the web 84.
In the assembled dock 10, the downwardly-opening channel 94 of the bumper rail 76 interengages with the upwardly-opening channel 46 of the side rail member 14 and the downwardly-depending skirt member 92 of the bumper rail 76 projects into the upwardly-opening channel 42, resulting in releasable assembly of the bumper rail 76 with the side rail 14. Temporary securement of the bumper rail 76 to the side rail 14 to prevent accidential dis-lodgement of the bumper rail 76 may be achieved using self-tapping screws 96, or any other convenient fixing means.
The portion of the projection 86 extending towards the side rail 14 overlaps the ends of the deck members 12~ as shown in Figure 6,to provide an aesthetic assembly. As seen in Figure 1, the bumper bar 32 attached to the end rails 16 extends beyond the ends o~ the end rails 16 to overlap the ends of the bumper bar 80.
The dock structure 10 of the present invention, suitable for assembly with floats 22 to form a floating dock, is comprised of a rigid aluminum frame 17, deck members 12 and aluminum bumper rails. The only wooden parts of the structure are the ~umper bars 32 and 80 which are only a minor portion of the overall structure, and may be replaced by other materials, such as, vinyl or ri~, if desired.
The dock structur~ 10 possesses many advantages 7~7~3 over conventional wooden dock structures. Thus, the structure may be assembled without special tools and skills and may be disassembled readily for removal from water bodies during freeze up, in contrast to wooden structures.
The aluminum is not readily corrodible or damaged by exposure to the elements and hence does not need replacement for many years in contrast to the wooden structures, does not absorb water and hence remains light in weight, easing removal from the water body, is inflammable and very durable. Any worn or bro~en parts have scrap value as aluminum and hence are 100% recyclable, in contrast to th~ difficulties of disposal of broken wooden parts. Repairs can be readily effected, owing to ease of disassembly of the parts.
The present invention, thereforer provides a dock structure which has considerable advanta~es over the prior art wooden structures. Modifications are possible within the scope ~f the invention.

Referring to the drawings, a dock s-tructure 10 comprises a plurality of generally parallel deck members 12 ~, . ., ~
: ' ' ' ~ '" ' ' ' ' ' ' ' ~1~7~78 constructed of aluminum releasably connected to a pair of parallel aluminum side rail members 14 extending generally perpendicularly to the decX members 12.
Aluminum end rail members 16 extend between and generally perpendicular to the ends of the side rail members 14 and are connected thereto.
The dock frame 17 is completed by an aluminum rail member 18 extending between and connected to the side rail members 14 at the approximate midpoint along their length. In the frame structure of Figure 8, additional aluminum rails 20 extend parallel to the side rails 14 and are connected between one end rail 16 and the centre rail 18 to provide strength and rigidity to the frame 17. In dock frames 17 of lesser width, as shown in Figure 10, the additional rails 20 may be omitted.
The dock frame 17 comprised of the rail members is rigid and is attached to one or more floats 22. The floats may be of any convenient form, for e~ample, hollow plastic floats. If the dock 10 is a standing structure, the frame 17 is connected to pillars or ground anchors.
The invention will be described particularly with reference to a flaati~g dock structure.
Each side rail mem~er 14 has a generally E-shaped cross-section opening outwardly of the dock frame 17 and each end rail member:l6 is of generally flat-based C-shaped cross-section opening inwardly of the doc~ frame 17, Adjacent ends of the side rail members and the end rails 16 are rigid-ly joined by angle plates 24 which are ~olted to both the side rai] 1~ and the end rail 16 by 3Q bolts 26.
The centre rail 18 and the additional rails 20, -1~3'7U3~'78 if any, are also of flat-based C-shaped cross-section, but the upper and lower projections of the additional rails 20 are cut away adjacent their ends to allow for entry into the C-shaped cross-section of the end rails 16 and centre r.ail. 18.
The centre rail 18 is connected at its ends to the side rails 14 by angle plates 26 which are bolted to both the side rail 14 and the centre rail 18. The additional rails 20 are connected to the end rails 16 by angle plates 28 which are bolted to both the rails 16 and 20 and to centre rail 18 by angle plates 30 which are bolted .
to both the rails 18 and 20.
OnLy one of the additional rails 20 need have the upper and lower projections cut away at both ends, while the other need have the projections cut`away at the end connected to the end rail 16, since this rail 20 does not project into the opening of the centre rail 18.
However, for ease of manufacture and assembly, it is preferred to have both additional rails 20 identically constructed, as illustrated.
The aluminum rail members 14, 16, 18 and 20 may b~ conveniently formed by extrusion, although any desired manufacturing technique may be adopted.
Each end rail 16 has a bumper bar 32 connected thereto in any convenient manner. Usually the bumper bar 32 is of rectangular of square cross-section and con-struct~d of wood, but any other convenient constructiQnal material may be used.
Each side raii mem~er 14 has a vertically-extending we~ 34 and three integrally-formed projections 36, 38 and 40 therefrom. The projection 36 extends r-- .
1~7~ 8 horizontally from the lower end of the web 34 and engages the upper surEace of the float 22.
The projection 38 is L-shaped and forms an upwardly-opening channel 42 with the web 34. The projection 40 includes a horizontally-extending portion 44 and an upwardly-opening channel-defining portion 46 at the end of the portion 44 remote from the web 34. The purpose of the channels 42 and 46 will become apparent hereinafter.
The horizontally-extending portion 44 has a plurality of upwardly-extending integrally formed laterally-thin and longitudinally-extending protrusions 48 equally spaced along the length of eacb side rail member 14 and equal in number to the number of the deck members 12.
Each of the protrusions 48 is undercut at its ends to define therein shoulders 50 and 52 respectively and undercuts S4 and 56 respectively. While the structure is illustrated with one protrusion 48 at each end for each deck mem~er 12, a plurality of such protrusions 48 may be provided for each deck member 12, for greater strength or rigidity.
Each deck member 12 has a continuous planar surface 58, preferably provided with a non-slip outer surface, which cooperates with other like surfaces to form a planar deck surface to the dock 10. Integral skirt portions 60 and 62 depend from adjacent the lateral sides of the planar surface 58 generally perpendicularly thereto.
At the lower end of each skirt portion 60 and 62 is a shoulder-engaging mem~er 64 and 66 respectively.
Each shoulder-engaying member includes a portion projecting inwaxdly of ~he skirt 60 or 62 towards the other and a shoulder Eace-engaging portion. ~enerally, the shoulder-~L~7~
engaging member 64 projects inwardly a greater distance than the shoulder-engaging member 66 and a distance substantially e~ual to the depth of the undercut 54.
While the undercuts 54 and 56 have the dimensions and depth approximately equal to the extremitv of the shoulder-engaging member 64, this arrangement is for convenience in assembly of the dock 10, allowing the longer shoulder-engaging member 64 to be inserted in either undercut 54 and 56 to engage both the shoulder and end wall of the undercut, so that the arrangement shown in Figures 4 and 5 with respect to the relative positions of the shoulder-engaging members 64 and 66, may be attained.
Ho~everl if desired, the undercuts 54 and 56 may be dimensioned such that the undercut 54 has a depth at least equal to the maximum distance of extension of the shoulder-engaging member 64 and the undercut 56 has a lesser -depth at least equal to the maximum distance of extension of the shoulder-engaging member 66.
Each shoulder 50 and 52 has a sloping outer surface 68 while the surface of the shoulder-engaging member 66 intended to engage the sloping surfaces 58 during assembly, as described below, is bevelled at 70.
The deck mem~ers 12 also include a pair of webs 72 depending from the planar surface 58 parall~l to the skirt portions 60 and 62 for engagement with the horizontally-extending portion 44. A single such web 72 may be used, if desixed, although it is preferred to provide the pair of such webs for strength and stability. Greater numbers of such webs 72 may be used, if desired.
Slots 74 are provided in each of the webs 72 for receiving the protrusion 48 therein. The interaction of the protrusion 48 with the slots 74 constitutes stop means and prevent longitudinal displacement of the deck members 12 relative to the side rails 14 in an assembled dockO In this way, a stable assembly is achieved.
Each deck member 12 has a thickness and size allowing limited flexibility when bent along along its longitudinal centre line. This flexibility, the dimensioning of the deck members 12, the dimensioning and shape of the protrusions 48 and the dimensioning o~ the shoulder-engaging members 64 and 66 combine to provide snap-fit means, read~ly releasably interlocking the deck mem~ers 12 to the side rails 14. The interlocking and releasing of the deck members 12 and side rai~s 14 is achievable without the use of special tools or skills.
As seen particularly in Figures 3 to 5, the deck members 12 are assembled with the side rails 14 at each intersection thereof by inserting the longer shoulder-engaging member 64 into the undercut 54 and pushing the shorter shoulder-engaging member 66 against the upper and outer surface of the shoulder 52, causing the deck member 12 to flex slightly about its centre line, thereby moving the shoulder-engaging members 64 and 66 a greater distance apart, so that the bevelled suxface 70 of the shoulder-engaging member 66 rides on and round.the surface 68 of shoulder 52 and snap fits into the undercut 56 in engagement with the underside of the shoulder 52. At the same time, the protrusions 18 extend into the slots 74.
Disassembly of the interlock is readily achieved ~y ~lexing the mem~er 12 about its centre line unt;l the shoulder-engaging members 6~ and 66 are spaced ~7Q~7~3 apart a distance su~ficient to remove the shoulder-engaging member 66 ~rom the undercut 56.
The disassembly of the deck members 12 and side rails 14 is not prevented by the stop means constituted by the interaction of the protrusion 48 with slots 74.
If desired, the additional rails 20 may be provided with one or more protrusions 48 with the webs 72 being provided with appropriate slots 74 for releasable interconnection of the deck members 12 to the additional rails 20 at their intersections to increase the rigidity and strength of the overall structure.
Additionally, while the protrusions 48 are shown as a single integral member, the protrusions may be formed in discontinuous mannerl typically having three separate parts, one at each end having the undercuts therein and a central tab for projection into the slot 74.
The dock 10 also is provided with a pair of side bumper rails 76 releasably connected one to each side rail 14. Each bumper rail 76 comprises an elongate aluminum member 78, which generally is formed by extrusion having a generally E-shaped cross-section opening towards the side rail 14 and a generally ~lat-based C-shaped cross-section opening away from the side rail 14. A bumper bar 80 of any convenient material, such as wood, plastic or rubber, havi~g a suitable cross-section, such as the gen-erally rectangular or square cross section illustrated or a part-circular cross-section, is received in the U-shaped cross-section opening of the elongate member 78 and secured therein, such as, by securing screws 82.
The elongate mem~er 78 includes a vertically-extending web 84 and integrally-~ormed projections 86, 88 and 90. The projection 86 extends horizontally on both _ g _ sides of the web 84 perpendicularly thereto. The projection 88 extends horizontally on both sides of the web 84 perpendicularly thereto and also includes a depending skirt portion 92 at the end of the projection 88 remote from the web 84 and closest to the side rail 14.
Theprojection 90 is L-shaped and forms a downwardly-opening channel 94 with the web 84.
In the assembled dock 10, the downwardly-opening channel 94 of the bumper rail 76 interengages with the upwardly-opening channel 46 of the side rail member 14 and the downwardly-depending skirt member 92 of the bumper rail 76 projects into the upwardly-opening channel 42, resulting in releasable assembly of the bumper rail 76 with the side rail 14. Temporary securement of the bumper rail 76 to the side rail 14 to prevent accidential dis-lodgement of the bumper rail 76 may be achieved using self-tapping screws 96, or any other convenient fixing means.
The portion of the projection 86 extending towards the side rail 14 overlaps the ends of the deck members 12~ as shown in Figure 6,to provide an aesthetic assembly. As seen in Figure 1, the bumper bar 32 attached to the end rails 16 extends beyond the ends o~ the end rails 16 to overlap the ends of the bumper bar 80.
The dock structure 10 of the present invention, suitable for assembly with floats 22 to form a floating dock, is comprised of a rigid aluminum frame 17, deck members 12 and aluminum bumper rails. The only wooden parts of the structure are the ~umper bars 32 and 80 which are only a minor portion of the overall structure, and may be replaced by other materials, such as, vinyl or ri~, if desired.
The dock structur~ 10 possesses many advantages 7~7~3 over conventional wooden dock structures. Thus, the structure may be assembled without special tools and skills and may be disassembled readily for removal from water bodies during freeze up, in contrast to wooden structures.
The aluminum is not readily corrodible or damaged by exposure to the elements and hence does not need replacement for many years in contrast to the wooden structures, does not absorb water and hence remains light in weight, easing removal from the water body, is inflammable and very durable. Any worn or bro~en parts have scrap value as aluminum and hence are 100% recyclable, in contrast to th~ difficulties of disposal of broken wooden parts. Repairs can be readily effected, owing to ease of disassembly of the parts.

3. The dock structure of claim 2, wherein each of said plurality of deck-forming members further includes first and second skirt members depending one from adjacent each lateral extremity of said planar portion, and said spacer means comprises a pair of webs depending from said planar portion parallel to each other and to said skirt members.
4. The dock structure of claim 3, including at least one vertical slot formed in each said web at each said intersection to constitute said cooperating element of said stop means integral with said deck-forming member and for receiving a protrusion integral with said side rails and constituting said cooperating element integral with said side rail.
5. The dock structure of claim 4, wherein said snap fit means comprises at least one continuous elongate protrusion extending from the side rail and in the direction of extension thereof, said continuous elongate protrusion including shoulders projecting in opposite directions generally parallel to and spaced from the adjacent surface of the side rail to define an undercut therewith and a generally central portion constituting said received protrusion and said snap fit means further including undercut engaging members formed on each of said deck-forming members constructed to snap fit into said under-cuts.
6. The dock structure of claim 1 including a pair of laterally spaced-apart longitudinally-extending aluminum end rails extending between and releasably connected to the side rails, said end rails and said side rails defining a substantially rigid rectangular frame structure.
7. The dock structure of claim 6, wherein said bumper rails and said end rails have bumper bars secured thereto around the periphery of the frame structure.
8. The dock structure of claim 6, wherein each of said side rails includes a vertically-extending web having an integrally-formed horizontally-extending member provided at the upper end thereof extending away from said frame structure and each of said end rails is of generally flat-based C-shaped cross-section opening inwardly of the frame structure.
9. The dock structure of claim 8, wherein each of said side rails further includes a first upwardly-opening channel member integrally formed at the and of said horizontally-extending member and a generally L-shaped cross-sectioned projection spaced vertically downwardly from said horizontally-extending member and defining with the web a second upwardly-opening channel, and each of said bumper rails includes a pair of downwardly-depending projections received one in each of said upwardly-opening channels to constitute said releasable connection between said side rails and said bumper rails.
10. The dock structure of claim 9, including means for temporarily preventing separation of said side rails and bumper rails.
11. The dock structure of claim 9, wherein each of said bumper rails includes a vertically-extending web having an integrally-formed horizontally-extending member provided at the lower end thereof extending towards the adjacent side rail and a first depending skirt member extending into said second upwardly-opening channel as said depending projection received therein, and a gener-ally L-shaped cross-section projection spaced vertically upwardly from said last-mentioned horizontally-extending member and defining with said web a downwardly-opening channel interengaging with said first upwardly-opening channel and including said depending projection received therein.
12. The dock structure of claim 11, wherein each of said bumper rails also includes a second integrally-formed horizontally-extending member provided at the upper end of said web extending towards the adjacent side rail and overlapping the ends of said deck-forming members.
13. The dock structure of claim 12, wherein each of said bumper rails also includes integrally formed third and fourth horizontally-extending members provided at the upper and lower ends of said web and extending away from the adjacent side rails and a generally rectangularly cross-sectioned elongate bumper bar engaging the web and the inner surface of the third and fourth horizontally-extending members and secured to the bumper rail.
