Apparatus fixture device and an installation method for fixing an apparatus

摘要

An apparatus fixture device for fixing an apparatus to a ceiling portion of a vehicle includes at least one pair of rails for carrying a load when the apparatus is installed. Each rail has a narrow opening groove and a pair of rack-shaped portions on both sides thereof. A block has loose-fitting holes and an upper width insertable into said opening groove. Bolts are loosely fitted into said holes of the block. A cylinder is loosely fitted between said bolt and said hole. Nut plates have a nut hole to be screwed with said bolt. When the bolt is turned and pushed upwardly, end portions of the nut plates extend across said opening groove and are placed on said pair of rack-shaped portions and pulled downward by a tightening force of said bolt screwed into said nut hole. A fixing member engages the apparatus to the block.
