PURPOSE:To facilitate mounting of a product by a method wherein four perforated bar-shaped plates are assembled in the form of, in which a distance between the two parallel plates of one pair is set equal to that between ceiling suspending bolts which are embedded inside a ceiling, and a distance between the two parallel plates of the other pair is set equal to that between holes for ceiling suspending metals which are attached to a body of the product to be mounted. CONSTITUTION:A pair of rectangular plates 1a and 1b mounted with ceiling suspending bolts in oblong holes 2 and another pair of rectangular plates 1c and 1d mounted with a suspending metal 7 of a product body 8 in other oblong holes 2 are assembled in the form of # with fixtures 5 and fixed by means of butterfly screws 6 and a holding plate 10 frictionally. The oblong hole of the rectangular plate 1 is shaped in such a manner that a circle of radium R which is larger than that of the ceiling suspending bolt 3 is opened at a distance of L1 and connected every two holes in the width of a diameter of the circle. The product body 8 is moved vertically by changing fastening positions of the ceiling suspending bolts 3, and horizontally by moving contacts between unfastening plates 1a and 1b and the plates 1c and 1d by loosening the butterfly screws 6. |
