Abstract

The nature of this unique design is that when the top and bottom female toggle on the middle support are simultaneously put on the male toggle of the side truss.
a collision fit is obtained. This is due to the angle which is above the female toggle on the top and under the female toggle on the bottom. There is a bolt which gets threaded through the female toggle, then continuing through the diagonal cross brace then threaded through the remaining female part of the toggle. The bolt then continues through into the male toggle in a pinned configuration due to a hole being drilled into the male toggle. Therefore, this allows the truss dock side sections to twist. The diagonal cross brace at each corner, as well as the mechanical connection at each mid support, limit the amount of twist. As example, if a wave were to lift one comer of the dock approximately 6", the dock can flex or twist then revert to the original static position without suffering the structural damage of a rigid welded frame if it were flexed.

Description

DISCLOSURE
This invention relates to a truss style marine dock system that is assembled from kit form.
5 It is common with truss style marine dock systems to provide the ability to walk on a horizontal surface above the water and provide boat dockage. Docks of this type are, however, are ridged because they are welded or a permanently bolted together without movement 10 permitted at the bolted connection.
I have found that this disadvantage may be overcome by providing a malelfemale toggle connection in combination with diagonal cross braces that are pinned to the side truss sections. Contrary to a rigid frame 15 design, when lifted, the dock will revert back to its original square form without distorting the frame. Such a toggle connection allows the ability of the truss style marine dock to flex in wave conditions without deforming, bending or cracking.
20 Figure 1 illustrates the embodiments of the invention. 1 is the angle of the mid section on top of the female toggle and 2 is the female toggle on top of the bottom mid section angel. Each mid section provides a collision fit when slid down the male toggle on the side truss 25 section. The mid sections (qty 2) and end sections (qty 2) span perpendicular between each side truss section.
At each female toggle location 5, there is a diagonal cross brace 3, which connects to the end of the mid sections on the top and bottom and the middle of the end mid sections therefore increasing tort Tonal and transverse rigidity in all four corners. A single bolt 4 is 5 used at each toggle location that holds the diagonal cross braces in place between two threaded surfaces of the female toggle. The same bolt 4 then continues to pin the female to the male toggle that is permanently welded to the side joist section 4 feet from the end.

Claims

1. It is a marine dock truss system in a kit form that is assemble through a male and female toggle connection that when assembled provides a collision fit.

2. The combination of the male and female toggle connection provide a limited amount of movement at joining location of the truss style dock frame therefore if a wave were to lift the dock, the dock will flex freely and revert back to its original shape without deformation or cracking at its connection points verses a ridge frame.

3. The diagonal cross braces from top to bottom in each corner help to maintain a level and square dock due to their transverse and tortional rigidity in the application of a truss style marine dock.
