Abstract
A cantilever assembly includes a cantilever arm having longitudinal fastening channels and slots in communication with the fastening channels. The assembly also includes an attachment bracket featuring a first leg portion and a second leg portion defining a seat there between with the leg portions featuring apertures. Bolts having threaded shafts are positioned through the apertures of the attachment bracket and engage the threaded bores of nut plates positioned in the fastening channels of the cantilever arm. As a result, when the bolts are turned, the nut plates engage side walls of the fastening channels and the distal ends of the bolts engage a central pipe portion of the cantilever arm.
Claims15
A cantilever assembly comprising:
- a) a cantilever arm having a first longitudinal fastening channel and a first slot in communication with the first longitudinal fastening channel, the first slot defined by spaced apart side walls;
- b) an attachment bracket featuring a first leg portion and a second leg portion, the first and second leg portions defining a seat therebetween with said first leg portion featuring a first aperture;
- c) said first aperture in alignment with the first slot of the cantilever arm when the cantilever arm is positioned in the seat of the attachment bracket;
- d) a first bolt having a threaded first shaft portion and a first head portion, wherein the first shaft portion extends into the first longitudinal fastening channel and the first head portion is positioned externally of the first longitudinal fastening channel;
- e) the first shaft portion of said first bolt movably passing through the first aperture of the attachment bracket;
- f) a first nut plate having a threaded bore and positioned within the first longitudinal fastening channel and threadedly engaging the threaded first shaft portion of the first bolt so that when the first bolt is rotated, the first nut plate engages the spaced apart side walls defining the first slot;
- and
- g) a first lock nut positioned on the first bolt of the first threaded bolt and positioned between the first head portion of the first bolt and a first exterior surface of the first leg portion of the attachment bracket,
- h) wherein the cantilever arm further includes a central pipe portion having an outer surface, the outer surface forming a part of the first longitudinal fastening channel at an opposite side of the first longitudinal fastening channel from the spaced apart side walls in a longitudinal direction of the first shaft portion, and wherein the first shaft portion of the first bolt includes a first distal end that directly engages the outer surface of the central pipe portion while the first nut plate engages the spaced apart side walls defining the first slot in response to rotation of the first bolt.
