Abstract

A mounting bracket of a jet assembly includes a connecting assembly and a mounting assembly. The connecting assembly includes a mounting arm, a linking arm, a mounting tab, and a rotating tab. The linking arm is rotatable relative to the mounting arm within a first plane. The mounting tab is mounted to the linking arm. The rotating tab is rotatable relative to the mounting tab within a second plane. The first plane is perpendicular to the second plane. The mounting assembly includes a securing body and a securing tab. The securing tab is mounted to the rotating tab.

First claim
