Patent ID: 7101083

Claim:
A device for holding a linear guide rail along a linearly extending vertical reference surface formed on an installation surface, said linear guide rail having a first side and a second side opposite said first side, said installation surface being provided with a vertical counter surface spaced apart from and in parallel with said reference surface and having a female thread hole formed between said reference surface and said counter surface, said holding device comprising: a pressing plate having a vertically extending central fitting hole through which a screw is insertible and a pair of opposing, inwardly downwardly tapered, first and second side surfaces, said screw being threadedly engageable with said female thread hole so that said pressing plate is fixed on said installation surface when said screw inserted through said central fitting hole is tightened into said female thread hole; a first pressure contacting piece having a tapered side face which is face-to-face engageable by said first tapered side surface of said pressing plate and a vertical side face opposite to said tapered side face and face-to-face engageable by said vertical counter surface; and a second pressure contacting piece having a tapered side face which is face-to-face engageable by said second tapered side surface of said pressing plate and a vertical side face opposite to said tapered side face and face-to-face engageable with said first side of said linear guide rail, wherein when said linear guide rail, said pressing plate and said first and second pressure contacting pieces are arranged on said installation surface such that said first pressure contacting piece is located between said first tapered side surface of said pressing plate and said vertical counter surface, said second pressure contacting piece is located between said second tapered side surface of said pressing plate and said first side of said linear guide rail and said linear guide rail is rested with said second side thereof being adjacent to said vertical reference surface and when said screw inserted through said central fitting hole of said pressing plate is tightened into said female thread hole, said first and second pressure contacting pieces are brought into pressure contact with said vertical counter surface and said first side of said linear guide rail, respectively, to press said linear guide rail against said vertical reference face.
