Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to dock structures; and more particularly, to an improved dock structure having adjustable fixtures.
2. State of the Prior Art
Dock structures have been known for many years. Generally, docks are known to exist to extend from a landmass or other fixed starting point, and extend over an area that is impassable or difficult to cross by normal foot traffic. Such areas can be over water, swampy terrain, or the like. With the general purpose of supporting a user, prior art docks were characteristically constructed with a predetermined width and length, affixed to the stable or passable landmass, or structure, and set upon supports extending to a support surface under the unstable area or water to be traversed. Docks have historically been constructed of wood. Wood structures are of course susceptible to rot and damage when exposed to the elements, and thereby become unsafe for human use.
In climates where the water or unstable terrain are subjected to freezing and thawing, the elements are known to damage or destroy dock supporting structures. This led prior art dock structures to be made removable to avoid the affects of the freezing and thawing conditions. It is known to put dock structures on wheels that can progress along the bottom or supporting surface under the water or unstable terrain. The wheeled configurations are adapted to allow the entire dock structure to be pulled back up onto the stable landmass when freezing is anticipated. These large structures are often heavy, ungainly and difficult to maneuver during the installation and extraction process.
The prior art has recognized the concern of rotting and deterioration of wood dock structures and have been improved through construction using materials that are not subjected to the rotting or deterioration process. Prior art docks have been fabricated of various types of metals, such as steel, which are heavy and subject to rusting and deterioration, though at a slower rate of decay then the wooden structures. Aluminum has been found to be a preferable construction material in that it is lightweight, has sufficient strength when properly designed, can be economically fabricated in desired shapes and is not subjected to the corrosive deterioration that other metals display.
Prior art aluminum structures for docks have been developed. Such prior art structures are normally fabricated in the size and configuration of the desired dock structure, and as a result, also tend to be large and unwieldy. Such aluminum structures are often fitted with wheeled assembly to allow the dock to be rolled into the unstable material or water to thereby support the dock structure at a predetermined level. Such prior art aluminum dock structures are characteristically constructed of members that are either welded, riveted, or bolted together. This type of structure is extremely unwieldy when the shape of the dock is desired to have dock sections extending laterally to the basic dock extension from the landmass. Such structures are also difficult to ship from point of manufacture to point of use. These types of prior art dock structures have the disadvantages of unwieldy sizes and shapes for installation and removal, and difficulty of assembly when multiple dock segments are utilized.
It is a primary object of this invention to provide an improved dock structure.
Another primary object of the invention is to provide an improved modular dock structure utilizing uniformly fabricated structural members.
Yet another object of this invention is to provide an improved dock structure having adjustable fixture positioning.
Another object of the invention is to provide an improved dock structure having a unique coupling mechanism for adjustably connecting various fixtures and dock sections.
A further object of the invention is to provide an improved structural member that is useful in constructing modular sections, where the structural member includes one or more retention channels to cooperate mounting structures to mount coupling hinge members and other fixtures.
A further object of the invention is to provide an improved coupling hinge structure to cooperate with associated dock sections.
Still a further object of the invention is to provide an improved dock structure having a plurality of dock sections interconnectable in selectable configurations utilizing an improved interconnection mechanism.
A further object of the invention is to provide an improved dock structure having a portion of a novel interconnection system integrally formed in the peripheral members of selected dock sections, and arranged to cooperate with an improved intercoupling fixture.
Another object of the invention is to provide an improved dock structure wherein one or more dock sections may be adapted to float.
Still a further object of the invention is to provide an improved dock structure having one or more dock sections supportable on the bottom support surface under the water or unstable area to be traversed.
Yet another object of the invention is to provide a modular dock structure wherein two or more dock sections allow varying dock configurations.
A further object of the invention is to provide a modular dock structure that is easy to ship to the location of intended use.
Still a further object of the invention is to provide a modular dock structure that is fabricated from extruded aluminum members for efficiency of manufacture structural strength, minimum weight and structural durability.
These and other more detailed and specific objectives will become clear from a consideration of the Drawings in conjunction with the Summary of Invention, together with the Detailed Description of the Preferred Embodiments.
SUMMARY OF THE INVENTION
The present invention includes a modular design particularly well-suited for variable configuration dock structures. One aspects of the invention is a novel structural member that has a face structure, a rear surface opposite the face structure, a lower member, and one or more longitudinal retention channels in the face surface. One embodiment utilizes a pair of parallel retention channels in the face surface to provide structural strength for the coupling action. The retention channels are adapted to cooperate with and slidably retain one or more mating mounting structures to affix various fixtures to an associated structural member. The various fixtures include mounting brackets that are adapted for use with a predetermined number of mounting structures to mount the associated fixture to a structural member. An additional retention channel in the lower member can be utilized to mount the structural member to a float device.
A structural member can be extruded from non-corrosive metal, such as aluminum, and can be cut to predetermined lengths to form modular sections to provide an efficient and cost-effective manufacturing system for various sizes of modular sections.
Modular sections having a pair of side members and a pair of end members interposed therebetween and constructed of one or more of the foregoing structural members can be selectively interconnected in any desired modular configuration by utilizing one or more coupling hinge structures mounted to the retention channels on the sections to be joined together, with all of the coupling hinge structures on the two associated sections joined together by one or more pin structures.
Various fixtures can be affixed to the sections having one or more of the novel structural members. The fixtures include mounting brackets having holes therethrough in cooperative alignment with associated ones of the retention channels. Mounting structures include bolts through associated holes and a nuts and collars retained in a mating relationship in associated ones of the retention channels, whereby a fixture including its mounting bracket can be moved to a desired position along an associated structural member and can be clamped in place by tightening the bolt and nut assemblies to pull the retained collars into contact with the retention channel ridges.
In addition to the coupling hinge structures used to join modular sections, various other fixtures capable of being mounted to the versatile joining and mounting structure of the structural member can include an adjustable leg structure with varying attachments, a clete structure, an adjustable support wheel structure, a vertically adjustable bumper structure, and railing structures.
The mounting portion of the various fixtures can be formed to a large extent from integrally formed extruded aluminum and cut to length required for cooperation with the associated structural member, thereby providing an efficient and cost-saving manufacturing system where various sizes of modular sections.
From the foregoing summary of the invention, it is apparent that the various stated purposes and objectives have been satisfied.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the following description, to the extent possible for clear description, elements that appear in different figures will bear the same reference numerals.
FIG. 1
is a perspective view of a dock section structure illustrating various aspects of the invention.
A dock section
10
is comprised of a pair of side members
12
and
14
and a pair of spaced-apart end members
16
and
18
. End member
16
has a pair of longitudinally extending retention channels
20
and
22
, and side member
12
is illustrated with a pair of longitudinal retention channels
24
and
26
. While two retention channels are shown in each of the members
12
and
16
, it should be understood that a single retention channel can be utilized, though two are the preferred embodiment for strength and ease of operation. It should be understood also that more than two retention channels can be utilized to provide additional strength.
A plurality of spaced-apart deck support members
30
are arranged between and affixed at their respective ends to side members
12
and
14
. Each of the plurality of spaced-apart deck support members
30
has a deck support surface
32
. Side members
12
and
14
have deck support surfaces
34
and
36
respectively, and spaced-apart end members
16
and
18
have deck support surfaces
38
and
40
respectively.
As will be described in more detail below, the retention channels
20
,
22
,
24
, and
26
are adapted to cooperate with mounting structures on various fixtures that are slidably engaged and retained within the respectively associated retention channel.
A number of fixtures can be associated with the various retention channels. These fixtures include a portion of a coupling hinge structure
42
mounted by mounting structures
44
and
46
having captive mounting portions within retention channel
20
. Similar mounting structures (not shown) cooperate with retention channel
22
. Mounting structures
44
and
46
are subject to being loosened to allow the coupling hinge portion
42
to be moved to any desired position in the directions of arrow
48
along the length of end member
16
. It is of course understood that multiple coupling hinge structures
42
can be associated with end member
16
, as will be described and illustrated below.
Other fixtures such as support leg
50
, clete
52
, and bumper
54
are associated with retention channels
24
and
26
in side member
12
.
Supporting structure
50
has a support leg
56
having a lower end
58
coupled to an auger
60
. A mounting bracket
62
, as will be described in more detail below, allows the leg structure
56
to be adjusted upwardly and downwardly in the direction of arrow
64
. Leg
56
can be rotated at its upper end
66
to cause the auger to drill into a supporting surface or to be removed from the supporting surface. Mounting structures
68
and
70
on either side of bracket
62
cooperate with retention structures
24
and
26
respectively, and allow the support structure
50
to be moved to a desired position in the directions of arrow
72
. The support structure will be described in more detail below. It is of course understood that the support leg
56
need not use the auger
60
, and instead, can support the structure on end
58
.
The clete fixture has a pair of upper mounting elements
74
and a pair of lower mounting elements
76
in cooperation with retention channels
24
and
26
, respectively. When the mounting elements
74
and
76
are loosened, the clete fixture
52
can be adjusted longitudinally along the length of side member
12
in the directions of arrow
78
,
The bumper structure
54
has a pair of upper mounting structures
80
and a pair of lower mounting structures
82
in cooperation with retention channels
24
and
26
, respectively. The mounting structures allow the bumper structure
54
to be adjusted along the length of side member
12
in the directions of arrow
84
. The structure of the bumper
54
, as will be described in more detail below, allows the bumper to be vertically adjusted upwardly or downwardly in the directions of arrow
86
. A railing structure
90
is illustrated affixed to the outside surface of end member
18
by bracket structures (not shown).
In the preferred embodiment, the retention channels
20
,
22
,
24
, and
26
would also exist in the surfaces (not shown) of side member
14
and end member
18
so that the fabrication process can utilize identical cross section structures. While this is preferred, it should be understood that side member or end member structures can be utilized without the described retention channels if such structure is desired for other manufacturing or functional purposes.
The improved dock structure
10
contemplates one or more deck sections (not shown) to be supported and mounted to deck support surfaces
32
,
34
,
36
,
38
and
40
.
FIG. 2
is a plan view of a dock structure and illustrates configuration flexibility of the invention.
Dock section

is illustrated coupled to dock section
10
-
2
with end member
18
-
1
coupled to end member
16
-
2
by coupling hinge structures
92
and
94
. Dock section
10
-
1
is coupled to dock section
10
-
3
wherein end member
16
-
1
is coupled to end member
18
-
3
by a pair of coupling hinge structures
96
and
98
. While two coupling hinge structures are illustrated at each dock section juncture, it is clear that one may suffice depending on the spacing of the cooperating member; and more than two can be used.
Dock section
10
-
1
is coupled to dock section
10
-
4
, which extends substantially perpendicular thereto. Side member
36
-
1
is coupled to end member
18
-
4
of dock section
10
-
4
by coupling hinge structures
100
and
102
.
This configuration is provided to illustrate that the overall length of a particular dock structure can be selectively made as long as desired by coupling together additional lengths of dock sections. Further, the modular design is such that various configurations can be accommodated as desired by connecting dock sections laterally as desired. Further, as described in
FIG. 1
, adjustments for positioning can be made along the various retention channels, and it is understood dock section
10
-
4
can be adjusted along the length of side member
36
-
1
to any desired positions as shown by arrow
104
.
FIG. 3
is a face view taken at
3
—
3
in FIG.
2
. This view illustrates the coupling hinge structures
94
and
98
between dock section
10
-
1
and dock section
10
-
2
, and dock section
10
-
1
and dock section
10
-
3
, respectively. The retention channels
24
-
1
and
26
-
1
in side member
12
-
1
are illustrated as substantially parallel and running substantially the entire length of side member
12
-
1
. It is understood that the spacing of the retention channels may be modified to accommodate the needs of the structure, and that the retention channels
24
-
1
and
26
-
1
need not necessarily extend the entire length of side member
12
-
1
. Similarly retention channels
24
-
2
and
26
-
2
are illustrated in side member
12
-
2
, and retention channels
24
-
3
and
26
-
3
are illustrated in side member
12
-
3
.
FIG. 4
is a cross-sectional view of a dock side member taken at
4
—
4
in FIG.
2
. Side member
12
has retention channels
24
and
26
formed in a shape to mate with and retain associated mounting portions of mounting structures on an associated fixture (not shown). The front member
110
has a face surface extending from the bottom of side member
12
to just above the upper lip
112
of retention channel
24
, is essentially smooth. An upper projection
114
has a face surface
116
having a number of parallel ridges running longitudinally of the length of side member
12
to strengthen projection
114
. A rear surface
118
is arranged in cooperation with deck support surface
34
to protect the edges of a deck member (not shown) that is to be supported on deck support surfaces
32
and
34
. It is of course understood that upper projection
114
need not be utilized in all embodiments, but that it does provide stability and protection for the one or more deck members that may be utilized on a dock section.
An additional longitudinal retention channel
120
is located at the underside of side member
12
. It also has a mating shape to cooperate with an associated mounting portion of a mounting structure (not shown) that may be affixed to the underside of side member
12
. A rear member
122
joins the deck support surface member and lower end of the side member. A strengthening web
124
joins the rear member
122
to the front member
110
between the retention channels
24
and
26
, thereby in combination forming a double box beam structure. One end of one of the plurality of spaced-apart deck support members
30
is affixed to rear member
122
. In a preferred embodiment the depth D
1
of deck support member
30
is in the order of about 2.5 inches and the distance D
2
from the bottom of deck support
30
to the bottom of side member
12
is in the order of about 2.0 inches. It is of course understood that these dimensions are illustrative only and that the overall size and dimensions of side member
12
and it's pertinent structures will be selected to accommodate the loads and operational conditions in which the improved dock structure will be utilized.
In the preferred embodiment, side member
12
is fabricated from extruded aluminum thereby being substantially noncorrosive in fresh water conditions. The preferred fabrication process lends itself to establishing an appropriate mating structure for retention channels
24
,
26
, and
120
. It is understood that various other methods of forming the retention channels will be obvious to those skilled in the art, without departing from the scope of the invention. It will likewise be apparent to those skilled in the art that the configuration of the rear member
122
and cross member
124
may be modified to include additional cross members for purposes of strengthening the structure, or removal of the cross member
124
for lighter structural usage and strength.
FIG. 5
is a cross-sectional view of a dock end member taken at
5
—
5
in FIG.
2
. End member
18
has a pair of longitudinal retention channels
20
and
22
parallelly disposed and spaced apart on its front surface
130
. The retention channel
20
and
22
have a mating shape to retain and slidably engage associated mounting portions of mounting structures used with associated fixtures. In a similar manner to that of FIG.
4
. End member
18
has an upper projection
132
whose rear surface
134
engages and protects the edge of deck member
136
. The deck member
136
is supported on deck support surface
40
of end member
18
. End member
18
has an additional longitudinal retention channel
138
longitudinally extending along its bottom portion. Back member
140
joins the support surface
40
and lower portion of end member
18
, and has a central web
142
joining the rear member
140
to the front member
130
. A gusset
144
is attached to a portion of rear member
140
and provides additional strength and rigidity for the load imparted to the end members.
Though gusset
144
could be the same height as end member
18
, in the preferred embodiment gusset
144
is positioned beneath the lower surface of deck member
136
a distance D
3
, which for the preferred embodiment is in the order of about 0.5 inch. The gusset
144
does not extend to the bottom of end member
18
, and is recessed a distance D
4
in the order of about 0.5 inch. Gusset
144
has a height D
5
in the order of about 3.5 inches. Again, as mentioned above, these dimensions have found to be advantageous for the configuration of end member
18
illustrated, but various differing dimensions and changes will be apparent those skilled in the art in the event different structural strengths are required for any particular application. Such changes of dimension or arrangement will not depart from the scope of the invention.
End member
18
, as illustrated, is fabricated utilizing an extrusion process of aluminum material, as described with respect to the side member illustrated in FIG.
4
.
It can be seen that the structural portions of the extruded aluminum portion of side member
12
and end member
18
are essentially identical in cross-section. The manufacturing process allows lengths of material to be fabricated and various lengths cut from the base stock can be fabricated as end members or side members. Such a configuration allows the extruded material to be cut to the various lengths desired and to be welded or otherwise affixed into the shapes shown in FIG.

FIG. 6
is a perspective view of a portion of a dock structure taken at
6
—

in FIG.
2
.
For illustration purposes, end member
16
-
1
has a pair of halves
98
-
1
and
98
-
2
of the coupling hinge structure
98
. Coupling hinge structure
98
-
1
is slidably mounted to retention channel
20
-
1
by mounting structures
150
and
152
cooperating with retention channel
20
-
1
. In a similar manner coupling hinge structure
98
-
2
is slidably retained in retention channel
20
-
1
by mounting structures
154
and
156
. Coupling hinge structure
98
-
1
is slidably engaged with retention channel
22
-
1
by mounting structures
158
and
160
. Similarly, coupling hinge element
98
-
2
is slidably retained to retention channel
22
-
1
by mounting structures
162
and
164
. Coupling hinge structure
98
-
1
has a cylindrical portion
166
aligned with a cylindrical portion
168
on coupling hinge structure
98
-
2
. These structures are arranged to cooperate with mating structures (not shown) on an adjacent end or side member. An elongated pin
170
is made up of a cylindrical metal rod
172
that is coated with a synthetic coating
174
over its outer surface. The pin structure
170
is of a cross sectional dimension to slidably mate with cylinder portions
166
and
168
, together with the mating portions of the mounting structures (not shown) on an associated dock member. Metal pin
172
is characteristically made of steel or other material having sufficient strength to hold dock section together, and the coupling structures
98
-
1
and
98
-
2
are characteristically made from aluminum. It is understood, of course, that these coupling structures could also be made of material other than aluminum.
The synthetic coating
174
on the connecting pin
170
serves several purposes. In the first instance, it protects the metallic rod
172
from exposure to water, thereby inhibiting any corrosion that might occur. Further, it provides a barrier between the surface of rod
172
and the inner surface of cylindrical members
166
and
168
, thereby eliminating or minimizing any corrosive action that might occur from contact of dissimilar metals. Finally, it provides a resilient contact that tends to hold the rod
172
in place, and minimizes any noise or knocking action that would be present in a metal-to-metal contact. While rod
170
tends to stay in place without any restraint, it should be understood that the ends of rod
172
could be threaded to receive restraining nuts (not shown), could be drilled to receive a cotter pin (not shown) or any other suitable method of holding pin
170
in place.
FIG. 7
is a top view of coupling hinge structures. It illustrates a structural member
180
having a deck support surface
182
and upward projection
184

198
,
200
, and
202
may be adjusted to any desired positions along the lengths of structural members
180
and
186
, respectively, as described above. Pin
170
, when inserted in the cylindrical structure, as described with reference to
FIG. 6
, of each of the coupling structures causes structural members
180
and
186
to be coupled together.
FIG. 8
is a side view of an adjustable coupling hinge structure for joining dock structures and coupling to a floatation device. Member
210
supports deck member
136
-
1
at its upper surface. Retention channel
212
cooperates with mounting structure
214
. Mounting structure
214
includes a bolt
216
that cooperates with captive nut
218
to hold captive collar
220
within the mating shape of retention channel
212
. As bolt head
216
is tightened, nut
218
is drawn into compressing force with collar
220
such that coupling hinge structure
222
is mounted firmly to the face of dock member
210
. In a similar manner mounting structure
224
cooperates with retention channel
226
. Coupling hinge member
228
is coupled to coupling hinge member
222
by pin
170
. Coupling hinge member
228
is coupled to dock structural member
230
by mounting structures
232
and
234
that cooperate with retention channels
236
and
238
respectively. In this illustration, lower retention channel
240
is not utilized.
A floatation structure
242
is mounted by mounting structure

FIG. 14
is a side view of an adjustable support post mounted to a dock frame member. The fixture structure
50
includes a vertical leg
56
having its lower end
58
affixed to an auger
60
. The leg is movable upwardly and downwardly, as indicated by arrow
64
within bracket
62
. Leg
56
has a cross-sectional shape, as is illustrated in
FIG. 15
, that can be gripped at its upper end
66
by a wrench (not shown) allowing leg
56
to be rotated in either direction as illustrated by arrow
294
. When positioning, then, rotation of end
66
in a first direction will cause auger
60
to drill into the supporting surface and will hold the associated dock section fixed in place. To remove the dock section, leg
56
is rotated in a second opposite direction causing auger
60
to back out of contact with the underlying surface. When the leg structure
56
is at a desired location, set screws
296
and
298
can be set to hold pressure on leg
56
. It is of course understood that other mechanisms for securing leg
56
with relation to bracket
62
can be used.
As described with regard to
FIG. 1
, mounting structure
68
cooperates with retention channel
24
and mounting structure
70
cooperates with retention channel
26
in member
12
. As previously described, member
12
is affixed to cross member
30
and cooperates with cross member
30
to support deck
136
.
FIG. 15
is a top view of the adjustable support post of FIG.
14
. In this view, it can be seen that there is a cylindrical member
300
disposed between the outer surface of leg
56
and the inner surface of housing
62
. The cylindrical member
300
acts as a sleeve and protects the inner surface of mounting bracket
62
from undue wear when leg
56
is subjected rotation.
FIG. 16
illustrates an adjustable wheel structure for use with a dock section. A structural member
310
has a pair of retention channels
312
and
314
having retention configurations similar to those described above. A first mounting bracket
316
is mounted to member
310
by upper mounting structure
318
and mounting structure
320
in cooperation with retention channel
312
. Lower mounting structure
322
and
324
are in mounting cooperation with retention channel
314
. A support leg
326
extends through mounting bracket
316
to be rotatably mounted at its lower end
328
to a wheel
330
. In some configurations the leg
326
provides enough strength to allow the structure to be rolled on wheel
330
without additional bracing. In operation, leg
326
is raised or lowered in the direction of arrows
332
to adjust member
310
to the desired height.
For those structures that require additional bracing to give sufficient strength to leg
326
, a brace arrangement comprised of leg
334
connecting arm
336
and bracket
338
can be used. Bracket
338
is affixed to leg
326
as by a bolt
340
or other suitable interconnection mechanism. Bracket
338
is rotatably coupled at rotation point
342
to one end of the connecting arm
336
. The bottom end of leg
334
is rotatably connected at rotation point
344
to the opposite end of the connecting arm
336
. A bracket
346
is coupled to retention channels
312
and
314
in a manner similar to that described relative to bracket
316
.
It can be seen, then, that as leg
326
is moved downwardly, it is necessary to adjust bracket
346
in the direction of arrow
348
to allow the bracing structure to keep leg
326
essentially vertical. Additional adjustment can be accomplished through raising or lowering leg
334
within bracket
346
as leg
326
that supports wheel
330
is raised or lowered. Once positioned, the mounting structures that clamp bracket
346
to member
310
can be tightened.
For leg structures that are sufficiently long or where the bottom is rough or mucky, it may be necessary to add an additional brace structure of the type just described.

352
. As illustrated, a first dock section
354
is positioned on the ground
350
and is coupled to dock section
356
in a manner as described above. Dock section
356
is shown supported by leg members
358
and
360
which are supported on the ground surface
350
. Dock section
362
is coupled at one end to dock section
356
and is supported at its other end by leg members
50
-
1
and
50
-
2
, comprising support structures that are augered into the surface ground
350
to provide a relatively fixed support of dock section
362
. Dock section
364
is of the floating variety and is coupled at one end to dock section
362
and its other end to dock section
366
. Floating dock sections
368
and
370
are coupled at their respective ends to opposite sides of dock section
366
. Dock section
366
at its further end is coupled to dock section
372
. Floating dock sections
374
and
376
are coupled along their mating side members, and dock section
372
is coupled at its opposite end to the side member of dock
376
. It can of course be seen that the modular structure allows virtually any desired dock configuration to be assembled from the modular dock sections. Further, various fixtures can be utilized with any of the dock sections in a manner described above.
Though the entire description has been rendered with regard to a modular dock system connected to a landmass or other fixed support, the modular sections can also be utilized to construct a float structure utilizing one or more sections coupled together as described. Anchor devices can be affixed to one or more of the clete structures, or can be hooked to retention structure (not shown) affixed to one or more of the lower retention channels.
The invention has been fully described in conjunction with Drawings in its preferred embodiment, and has been described in its presently contemplated best mode.
