Definitions

  • Door closers of the above type are made DE 92 03 870 U1 and from US 2003/0093872 A1 known.
  • a closer shaft is rotatably mounted on a door closer housing about a shaft axis and passes through a cylindrical interior of the door closer housing.
  • a closing piston is arranged in the interior of the door closer housing on one side of the closer shaft and movably guided along a housing axis, which is formed by the cylinder axis of the cylindrical interior of the door closer housing.
  • a helical spring is arranged in the cylindrical interior of the door closer housing, which is supported on the one hand on the closing piston and on the other hand on a front-side housing cover of the door closer housing.
  • rotational movements of the closer shaft are converted to the shaft axis in linear movements of the closing piston along the housing axis or linear movements of the closing piston along the housing axis in rotational movements of the closer shaft about the shaft axis. If the door leaf provided with the door closer is turned open, the closer shaft is rotated about the shaft axis. Due to the rotational movement, the closer shaft drives the closing piston under bias of the coil spring arranged between the closing piston and the front-side housing cover with a movement along the housing axis of the door closer housing.
  • the previously preloaded coil spring lengthens and thereby drives the closing piston with a movement directed against the closer shaft along the housing axis of the door closer housing.
  • the closer shaft is rotated about the shaft axis and the rotational movement of the closer shaft causes via the linkage an automatic closing movement of the door leaf.
  • the bias of the coil spring and thus the force exerted to automatically close the open door leaf closing force and to be overcome when opening the door panel counterforce is adjustable.
  • the coil spring is not supported on the side remote from the closing piston side directly on the front-side housing cover of the door closer housing but rather on a spring abutment which rests on an adjusting spindle.
  • the adjusting spindle extends with a spindle axis along the housing axis of the door closer housing and is rotatably mounted on the front-side cover of the door closer housing about the spindle axis but in the direction of the spindle axis.
  • An external thread of the adjusting spindle meshes with an internal thread of the spring abutment.
  • the spring abutment In the opposite direction, the spring abutment can be moved until it abuts against the front-side housing cover of the door closer housing. In its end positions, the spring abutment bears against the respective end stop. If, after reaching the end position, the adjusting spindle continues to be acted upon in the relevant direction of rotation, the spring abutment is braced against the respective end stop. Should the bias the coil spring are changed starting from these ratios, the spring abutment is first to be released from the respective end stop. For this purpose, the adjusting spindle is to be rotated in a direction of rotation which is opposite to the direction of rotation of the adjusting spindle when approaching the end stop by the spring abutment.
  • a rotational movement of the adjusting spindle relative to the spring abutment is generated between the spring abutment and the helical spring supported on the spring abutment, due to which the spring abutment together with the helical spring forms a non-rotatable unit and does not rotate with the rotationally actuated adjusting spindle.
  • the spring abutment on its outer circumference with radial projections and the door closer housing on his Inner wall to be provided with along the housing axis of the door closer housing extending guide grooves, in which engage the radial projections of the spring abutment.
  • the object of the present invention starting from the generic prior art is to provide a door closer with an overload protection for the device for adjusting the bias of the closing spring.
  • the spring abutment is designed as an abutment circular disc concentric with the spindle axis of the screw drive and with the interior of the door closer housing, whose diameter corresponds at most to the diameter of the interior of the door closer housing.
  • the abutment circular disc can be provided with a low production engineering and with a low financial cost.
  • a constructively elaborate Longitudinal guide of the abutment circular disc along the spindle axis of the screw drive or the housing axis of the door closer housing is not provided.
  • the application of force to the spring abutment by the closing spring ensures that after the movement of the spring abutment into the closing piston-side end position and / or into the housing-side end position and the associated "caking" of the spring abutment at the respective end stop, an action on the adjusting spindle in the corresponding direction of rotation Rotary movement of the adjusting spindle relative to the spring abutment has the consequence and thus the spring abutment is released from the previously approached end stop.
  • the rotational movement of the adjusting spindle should end in the clamping direction of rotation and in the direction of relaxation as soon as the spring abutment has reached the closing piston-side end position or the housing-side end position.
  • the adjusting spindle after reaching the Schiererkolben salen end position by the spring abutment further in the clamping direction of rotation or after reaching the housing-side end position by the spring abutment further in the relaxation direction of rotation is subjected to force.
  • supported on the spring abutment closing spring allows that the adjusting spindle is jointly rotated with the spring abutment acting on the respective end stop in the clamping direction of rotation or in the relaxation direction of rotation.
  • the support of the closing spring on the spring abutment assumes the function of a slip clutch.
  • an overload protection is provided for the device for adjusting the bias of the closing spring.
  • a stop plate is provided as Schconvergeerkolben industrialer end stop and / or as a housing-side end stop for the spring abutment in a preferred embodiment of the invention.
  • the plate-like end stop provides a relatively large-scale system for moving in the respective end position spring abutment and ensures in this way for defined conditions at the respective end stop.
  • the claims 4 to 11 relate to the invention preferred measures to ensure a functionally reliable adjustment of the bias of the shutter spring.

  • the thread pitch of the threaded actuator according to the invention is such that for adjusting the bias of the closing spring, the adjusting spindle can be rotated relative to the spring abutment and that at the same time excluded from the application of force to the spring abutment by the closing spring rotational movement of the spring abutment relative to the adjusting spindle is.

  • a circular stop disc 8 is provided, which is riveted to the shaft 4 of the adjusting spindle 2.
  • a likewise disc-like housing-side end stop for the spring plate 7 is formed in the form of an outer collar 9 at a distance from the stop disc 8 to the shaft 4 of the adjusting spindle 2.
  • the adjusting spindle 2 has a sealing groove 10 and an actuating end 11 with a hexagon socket 12 ( FIG. 2 ).

  • the spring plate 7 is acted upon on the side remote from the housing cover 14 side by a closing spring designed as a helical spring 18.
  • the closing spring 18 is supported directly on the spring plate 7.
  • the closing spring 18 has a coincident with the spindle axis 3 of the adjusting spindle 2 and the housing axis 15 of the door closer housing 13 spring axis 19 and is biased along the spring axis 19 between the spring plate 7 and a conventional closer piston not shown in the figures of the door closer. Due to its bias, the closing spring 18 acts on the spring plate 7 along the spring axis 19 with an in FIG. 2 rightward force. Under the action of this force, the adjusting spindle 2 is supported with the rear side of the outer collar 9 via a sliding ring on the housing cover 14. An inserted into the seal groove 10 of the adjusting spindle 2 sealing ring 20th seals a cylindrical interior 21 of the door closer housing 13 from the environment.

  • the closer spring 18 is biased by means of the screw drive maximum 1.
  • the spring plate 7 is in its Sch Strukturerkolben folken end position. In this position, the spring plate 7 has been moved by a rotational actuation of the adjusting spindle 2 in the clamping direction of rotation 16. Due to the rotational actuation of the adjusting spindle 2 in the clamping direction of rotation 16, the spring plate 7 has performed a clamping feed movement in the direction of an arrow 22. In the course of the clamping feed movement of the spring plate 7 came to the stop plate 8 to the plant. As a result of a corresponding rotational actuation of the adjusting spindle 2, the spring plate 7 was braced axially against the stop plate 8 to a small extent.
