A portable dock system consisting of aluminum tubular longitudinal and transverse elements, arranged to provide high torsional rigidity. The design incorporates an integral handle for installation and a guide and clamp system for leg installation. These elements permit the easy installation of the dock without use of floats, wheels or hinges.

[ I claim:] [1.] A modular section for use in a dock comprising:first and second longitudinal members in parallel, spaced relation, each longitudinal member having a lakeward end and a shoreward end;a lakeward transverse member connected to and extending between the lakeward ends of the first and second longitudinal members;a shoreward transverse member connected to and extending between the shoreward ends of the first and second longitudinal members;a pair of support legs, one connected to each of the first and second longitudinal members adjacent the lakeward end of such longitudinal member; andthe first and second longitudinal members and the lakeward and shoreward transverse members being substantially in a common plane and being formed of lightweight tubular material with rigid connections such that a torque applied to the shoreward transverse member that is in a direction to cause rotation about a substantially horizontal axis and is sufficient to remove all load from one of the support legs causes no substantial deflection of the first and second longitudinal members and the lakeward and shoreward transverse members out of their common plane, and;further comprising means for connecting the first and second longitudinal members of that section to third and fourth longitudinal members of another section of like structure so that the shoreward end of the third longitudinal member abuts the lakeward end of the first longitudinal member and the shoreward end of the the fourth longitudinal member abuts the lakeward end of the second longitudinal member with the shoreward transverse member connecting the third and fourth longitudinal members lying parallel to and adjacent to the lakeward transverse member connecting the first and second longitudinal members, said means for connecting comprising:a slot in the bottom of each of the first and second longitudinal members adjacent to their associated lakeward transverse member;a hook plate attached to the inside of each of the third and fourth longitudinal members, each said hook plate having a tab that extends out of the longitudinal member to which it is attached for insertion through and out of the slot in a corresponding one of the first and second longitudinal members; anda pin for passing through a hole in a portion of the tab of each hook plate that extends out of the corresponding one of the first and second longitudinal members.
