Definitions

  • the present invention obviates such drawback. It relates to a door check of the type having a braking piston whose rod is provided with a head having, on the one hand, on its upper surface a chevron-shaped transverse groove in which a roller is housed, this roller being eccentrically mounted on a shaft carrying an arm linking the door check with the door frame, and, on the other hand, on its lower surface a longitudinal groove inside which a finger fixed in the casing of said door check is adapted to slide.
  • FIG. 2 is a sectional view of same taken on the line 22 of FIG. 1, and
  • the door check shown in the drawing includes a piston 2 movable along an axis A inside a bushing 3 inserted in the casing 4. Piston 2 moves in one direction upon the opening of the door, and in the other direction under the action of a spring 5 previously compressed, this latter move taking place when the door is being closed; oil contained in a space 6 passes into the interior of casing 4 through a calibrated port 7 and channels, shown in part at 19, piston 2 and bushing 3, thus acting as a conventional dashpot assembly which slows down the closing motion of the door.
  • said cooperating coupling means comprises a rod joined to said piston and a head secured to said rod, said groove being formed on said head, said spring means being disposed between said piston and said head.
