Definitions

  • the present invention relates to a door closer for actuating a door leaf with a locking device.
  • Door closers usually comprise an output shaft and a closing spring designed to store the closing energy.
  • the output shaft By pressing the door by a user, the output shaft is rotated. The movement is transmitted within the door closer to the closing spring and thus stores the energy required to close the door. During the closing process, the closing spring relaxes. This leads to the rotation of the output shaft and consequently to the movement of the door leaf.
  • the door closer can be attached directly to the door leaf. In this case, the power transmission from the output shaft to the wall or to the frame via a scissor linkage or a slide rail linkage takes place. On the other hand, the door closer can also be attached to the frame or on the wall. Then, the power is transmitted from the output shaft to the door by means of a slide rail linkage or a scissors linkage.
  • a slide rail is usually used.
  • this slide is an external locking device for fixing a slide rail lever.
  • the disadvantage is that due to the small slides only correspondingly small holding forces can be realized.
  • the maximum pivoting range of the door is limited by previously known, not traversable systems within the slide rail. Scissors linkage can not be combined with these known locking devices.
  • both the setting and the wiring of the known external locking devices impractical.
  • the previously known locking devices are often optically not appealing and after initial installation no longer changeable.
  • Other previously known solutions are mounted on the floor and usually disturb the user of the door.
  • hydraulic systems are known in which individual components are blocked within the door closer by means of hydraulic pressure or clearance spaces. In these variants, both the production and maintenance and the scheme is very expensive.
  • a door closer for actuating a door leaf comprising an output shaft and a drive unit for the translation between a rotation of the output shaft and a linear movement of the drive unit. If the door closer is fastened directly to the door leaf, the output shaft serves to transmit power to a wall or frame by means of a linkage. If the door closer fixed to a wall or a frame, so the output shaft is used for power transmission by means of a linkage to the door leaf.
  • the axis of rotation of the door leaf can be connected coaxially to the output shaft.
  • a first latching lug is coupled to the drive unit.
  • the door closer comprises a locking device designed to block and release the drive unit with one to the first Detent nose complementary second detent.
  • “Complementary locking lugs” means in this context that the two locking lugs are adapted to form a positive engagement with each other.
  • the door closer comprises a fluid-tight housing for receiving the drive unit.
  • the output shaft protrudes.
  • the door closer comprises a rod, which is coupled with a first end to the drive unit and protrudes with the second end of the fluid-tight housing. At the second end of the rod, outside the fluid-tight housing, there is the first latch.
  • the locking device can be arranged outside the fluid-tight housing.
  • the fluid-tight housing is filled in particular with oil in order to ensure a low-friction mounting of the drive unit.
  • a closer spring particularly preferably acts on the drive unit.
  • the closing spring is arranged in particular in the fluid-tight housing. In particular, one end of the closing spring is supported on a fixed end of the housing. The other end of the closing spring is applied to the drive unit.
  • the rod preferably extends from the drive unit through the helical shutter spring to the locking device.
  • the locking device preferably comprises an electromagnet for actuating the second latching lug.
  • the electromagnet is arranged such that, when energized, it makes it possible to lock the first latching lug.
  • the solenoid is deactivated.
  • the first locking lug releases from the locking device and the door is closed, in particular by means of the force of the closing spring.
  • first latching lug and / or the second latching lug are rotatably mounted.
  • a first spring generates a torque on the first detent and / or a second spring a torque on the second detent.
  • the second latching lug is located on a lever, wherein this lever is mounted on the locking device via a rotation axis. On one side of the axis of rotation is the second detent. On the other side of the axis of rotation of the electromagnet acts.
  • a first lever arm from the second latching lug to the rotation axis is in particular shorter than a second lever arm from the rotation axis to the electromagnet.
  • the door closer particularly preferably comprises a common mounting plate on which the housing and the locking device are mounted.
  • the locking device is fastened by means of an adjusting device on the mounting plate. This makes it possible to set a distance between the first latching lug and the second latching lug, whereby ultimately the opening angle of the door is set at which the locking device engages.
  • the door closer with locking device can now serve on the one hand for fixing the door leaf or on the other hand only for detecting the closing spring. If only the closing spring is detected, then the door is in the so-called "freewheel". During this freewheel, the door can be opened and closed with a very small amount of force because the closing spring does not have to be tensioned during the opening process.
  • the door closer comprises an overrunning clutch between the first latching lug and the output shaft, so that with the locking device, only the closing spring, but not the output shaft is blocked.
  • the drive unit may comprise a toothed rack.
  • a gear is then arranged, which is in engagement with the rack of the drive unit.
  • the drive unit is designed as a, in the housing sliding piston. This piston is slotted and includes the rack inside the slot. If in this case the door closer according to the invention is used for fixing the entire door leaf, then the first latching lug is firmly connected to the drive unit, in particular this piston.
  • the first latch is firmly connected to the second end of the rod. The rod is connected to the first end fixed to the drive unit. To realize a freewheel of the door also the rod is used.
  • a plate At the first end of the rod is then a plate. This plate is loosely attached to the drive unit. Furthermore, the closing spring is supported at one end against the plate and at the other end against the housing. When opening the door for the first time, the closing spring is pre-tensioned via the drive unit and the plate. Then the rod is blocked with the locking device according to the invention. When re-closing the door manually, the drive unit lifts off the plate and is free to move without being spring-loaded. Only when releasing the locking device relaxes the closing spring and it comes to rest the plate on the drive unit and thus spring-loaded closing the door.
  • a cam disc is arranged on the output shaft.
  • the drive unit then comprises at least one pressure roller for transmitting power to the cam disk.
  • This pressure roller is arranged in particular in an opening piston.
  • This opening piston slides in the housing.
  • a closing piston is still provided in the housing.
  • another pressure roller is arranged, which also rolls on the cam.
  • FIGS. 1 to 6 Based on FIGS. 1 to 6 a door closer 1 according to the first embodiment will be explained in more detail.

  • a first pressure roller 13 is mounted in the opening piston 12.
  • a second pressure roller 15 is mounted in the closing piston 14.
  • the first and second pressure rollers 13, 15 roll on two opposite sides of the cam disk 16.
  • a closing spring 17 is located in the housing 2. One end of the closing spring 17 bears against the opening piston 12. With the other end, the closing spring 17 is supported against a stationary end of the housing 2, in particular against the second closure lid 10.
  • the rod 5 is coupled with a first end to the drive unit 4, in particular to the opening piston 12. A second end 7 of the rod 5 protrudes through the second closure lid 10, so that the second end 7 of the rod 5 is located outside the fluid-tight housing 2.
  • the closing spring 17 is designed as a spiral spring, so that the rod 5 can extend through the closing spring 17 therethrough.
  • the output shaft 3 When opening the door leaf, the output shaft 3 is rotated. Thereafter, the opening piston 12 and the closing piston 14 moves to the right. During the closing operation, the opening piston 12 and the closing piston 14 move to the left, whereby the force is transmitted to the cam disk 16 via the pressure roller 13. This results in a conversion of the linear movement of the drive unit 4 in a rotational Movement of the output shaft 3.
