Embodiment Construction

[0033] FIG. 1 shows an interior door closer 1 , which is connected to the fixing device 2 via respective connecting screws 6 . The door closer 1 has lateral flanks 16 which merge into radii 18 and 19 . The interior door closer 1 is closed at both ends in the housing 7 by means of locking screws 13 and 14 . The locking screw 13 preferably has a polygon 10 which is located outside the housing 7 and the locking screw 13 . The polygon 10 is connected to a bevel gear 8 which is in operative connection with another bevel gear 9 . The bevel gear 9 is also connected to an adjusting sleeve 11 which is embedded in the fixing device 2 . The spring force can thus be adjusted without difficulty from above the door and the installed interior door closer 1 by, for example, an inner hexagon 12 in the adjustment sleeve 11 . In addition, each fixing hole 5 is provided in the fixing device 2 for fixing the door closer 1 together with the fixing device 2 in a groove of the door. Projecting fr...

Abstract

The door closer capable of being hidden inside door leaf or frame includes one casing with one fixing unit for fixing the parts inside the casing; one driving shaft including one cam disc with two operating surfaces; one spring force regulating device with one regulating sleeve; one operating arm with one end connected to the driving shaft and the other end connected rotatablely to one sliding block capable of sliding inside one slideway; one rotary support; one opening piston loaded with one spring energy accumulator; one buffering piston will one roller and one valve; and one blocking screwunit to close the first side of the casing and with one valve and one screw.

Description

technical field [0001] The invention relates to a door closer for discreet installation in a door leaf or a profiled door frame of a door leaf, which door closer is equipped with both a sliding rail link and a sliding rail, wherein the sliding rail is in a door frame embedded in a groove. [0002] The door closer has a drive shaft that includes a cam disc with two cam working surfaces. The cam disk is operatively connected on the one hand with an opening piston to which a spring device acting in the closing direction of the actuable shaft is connected and on the other side is operatively connected with a damping piston on the opposite side of the cam disk. Background technique [0003] One such door closer for mounting in a door leaf or frame is known, which comprises a toothed wheel cooperating with a closing shaft in a rack piston. A great disadvantage of such a door closer is that, due to the toothed rack used, the door closer in combination with a two-arm lever mechani...
