Abstract

1515217 Door closers VEREINIGTE BAUBESCHLAGFABRIKEN GRETSCH & CO GmbH 19 July 1976 [7 Aug 1975] 29919/76 Heading E2M A door closer includes a spindle 2 protruding from a housing 1, a closer spring 7 and, laterally beside the spring 7, a piston 9 and cylinder 6 of a damper 8, the spindle 2 carrying two cam discs 3, 4 which act respectively on the spring 7 and damper 8 on rotation of the spindle 2, in each case through a rocker arm 13, 25. Each rocker arm 13, 25 abuts through a roller 17, 28 on the cam disc 3, 4 and through another roller 12, 29 on the spring 7 or damper 8, the rocker arms 13, 25 being mounted approximately opposite to one another at 14, 26 in the housing 1. The longitudinal axes 19, 31 of the spring 7 and damper 8 remain fixed relative to the housing 1. Preferably as shown, the spring 7 is arranged parallel to but higher than the damper 8 in the housing 1. The spring 7 is guided in a cylinder 5 and surrounds and abuts against a bolt 11 which carries the roller 12. The run-off face 18 of the arm 13 is so curved that its tangential surface at its contact with the roller 12 is always perpendicular to the axis 19. The roller 29 is mounted in a recess 35 of the rocker arm 25 and abuts on a run-off face 30 provided on an extension of the piston 9. The stress in the spring 7 is adjusted by means of a screw 22 seated eccentrically in a disc 20 which has a collar 21 bearing on the end of the spring 7 remote from the bolt 11. The disc 20 has a recess 24 into which fits a circlip 23 on the screw 22 at maximum spring stress.
