  • the adjusting device has an adjusting screw with a threaded section and a screw nut which is adjustably mounted between two end positions and which engages with the threaded section.
  • the force of the spring device acting on the actuator can be adjusted by adjusting the screw nut along the threaded section.
  • the adjusting screw At an end of the thread facing the head of the adjusting screw, the adjusting screw has an unthreaded end region, so that jamming between the screw nut and a head of the adjusting screw is prevented.
  • a spring element is provided, by means of which the screw nut can be acted upon away from the head of the adjusting screw, so that the spring element can re-enter the thread after being transferred into the threadless area.
  • a cover fitting in the form of a cover plate for holding a cover or a flap of a piece of furniture is known.
  • the lid plate serves to hold the lid in an open position.
  • the lid plate has a first arm and a second arm.
  • the second arm is connected to the first arm so that it can pivot about a pivot axis between an open position and a closed position.
  • Spring means apply force to the second arm in the direction of the open position.
  • the second arm generates a force on the cover in the direction of the open position, so that the cover is held at least in the open position.
  • the cover plate has a spring tensioner against which the spring means are axially supported.
  • the spring tensioner has guide pins onto which spring means in the form of spiral springs are slipped.
  • the spring tensioner is supported on the inside against a housing of the cover plate via a screw that is screwed into the spring tensioner. Through a hole in the housing, the screw can be adjusted with a screwdriver so that the spring tensioner can be moved axially against the spring force of the spiral springs and preloads the spiral springs.
  • the object of the present invention is to provide a cover fitting which prevents the abutment from jamming and is of simple construction.
  • the torque limiting arrangement limits the maximum torque acting on the adjusting element and jamming of the abutment and overloading of the adjusting element or the abutment can be avoided.
  • the fitter can use sensors to record slipping of the torque limiting clutch when a maximum torque that can be transmitted by the torque limiting arrangement is exceeded. The fitter can thus feel that the at least one end position has been reached.
  • the adjusting element and the control element can be connected in a rotationally fixed manner via the torque limiting arrangement.
  • the torque limiting arrangement can have a first force transmission surface on the adjusting element and a first force transmission surface on the control element, which are mutually in abutment and are each arranged at an incline with respect to a radial plane relative to the longitudinal axis. Due to the inclination of the first force transmission surfaces with respect to the radial plane relative to the longitudinal axis, the first force transmission surfaces form a ramp mechanism in the axial direction.
  • the first transmittable torque results essentially from the inclination of the first force transmission surfaces, the coefficient of friction between the two first force transmission surfaces and the pretensioning force acting on the abutment.
  • the adjustment element together with the abutment is axially away from the control element against the biasing force of the at least one spring element, i.e. H. up the ramp, moved.

  • the first force transmission surfaces of the adjusting element and the control element can in particular be arranged circumferentially around the longitudinal axis. It is possible that the first force transmission surfaces of the adjusting element and of the control element are each designed as helical ramp surfaces.
  • the first force transmission surfaces of the adjusting element and of the control element can each follow a helical line that extends, for example, over 340 degrees, 360 degrees, 380 degrees or multiples of 360 degrees.
  • the helical line can be oriented in the opposite direction to the thread of the adjusting element or the mating thread of the abutment.
  • the first force transmission surface of the adjusting element can be designed as the first thread flank of a transmission thread and the first force transmission surface of the control element as the first thread flank of a transmission counter-thread, the transmission thread and the transmission counter-thread engaging with one another.
  • the adjusting element After the control element has rotated by the respective angular amount of the helical line relative to the adjusting element when the abutment rests against the stop, the adjusting element is axially released together with the abutment, so that the adjusting element moves back axially together with the abutment by the biasing force of the at least one spring element is, the first force transmission surfaces of the adjusting element and the control element in turn come into contact with one another. If the control element is rotated further with respect to the adjusting element or if the control element continues to be subjected to a torque greater than the first transmittable torque, the sequence described above is repeated until the torque acting on the control element is less than the first transmittable torque. The resulting cyclical axial movement of the adjusting element together with the abutment can be referred to as ratcheting.
  • the first force transmission surfaces of the adjusting element and the control element can each be inclined at an angle ⁇ with respect to the radial plane relative to the longitudinal axis.
  • the angle ⁇ of the first force transmission surfaces can be selected to be constant over the extent in the circumferential direction of the first force transmission surfaces.
  • the angle ⁇ can be selected to be larger in terms of amount than the pitch angle of the thread of the adjusting element or the mating thread of the abutment.
  • the angle ⁇ can also be oriented in the opposite direction to the pitch of the thread of the adjusting element. It is also conceivable that the angle ⁇ is designed to be variable over the extent in the circumferential direction of the first force transmission surfaces. This results in a defined characteristic of the torque to be transmitted as a function of the angle of rotation between the adjusting element and the control element.
  • the torque limiting arrangement can have a second force transmission surface on the adjusting element and a second force transmission surface on the control element, each of which is inclined relative to a radial plane relative to the longitudinal axis.
  • the second force transmission surfaces can act as blocking surfaces, so that when the control element is rotated in the second direction, the control element and the adjustment element are connected in a rotationally fixed manner via the torque limiting arrangement.
  • the second force transmission surface of the adjusting element can be designed as the second thread flank of the transmission thread and the second force transmission surface of the control element as the second thread flank of the transmission counter-thread.
  • the cover fitting has a housing in which the at least one spring element is arranged and in which the abutment is axially guided so that it cannot rotate.
  • the adjusting element can be mounted in the housing so as to rotate about the longitudinal axis.
  • the adjusting element can also be mounted in the housing so as to be axially displaceable along the longitudinal axis.
  • the adjusting element can have a bearing section which is arranged axially displaceably in an opening of the housing which is designed to be complementary to the bearing section.

  • the latter has a threadless section 30. If the abutment 15 is moved in the direction from the first end position into the second end position, the mating thread 21 of the abutment 15 emerges from the thread 20 of the adjusting element 19. In this position, the adjusting element 19 can rotate freely with respect to the abutment 15 without the abutment 15 being axially displaced, since the mating thread 21 is out of engagement with the thread 20. Jamming in the upper end position is therefore impossible.
