Definitions

  • the invention relates to a door drive with an output shaft for coupling the door drive to a power transmission element.
  • the invention also relates to a method for assembling a door drive.
  • the problem with door drives is that the door drive has to be adapted to different mounting positions.
  • the vertical distance between the door lintel and the installed door drive can assume different values depending on the installation conditions.
  • a variant of the door drive can be operated in different assembly positions, it is known from the prior art to extend the output shaft of the door drive with an extension element if necessary.
  • the length of the extension element is usually chosen so that the force transmission element, which is usually formed by a linkage and is attached to the end of the extension element spaced apart from the door drive, is arranged essentially horizontally.
  • the disadvantage here is that the extension element is kept in several different lengths and an extension element with the required length has to be selected when installing the door drive.
  • an extension element of great length can be kept in stock, the extension element first having to be brought to the required length when the door drive is installed, for example by sawing off, which is also disadvantageous.
  • a door drive known from the prior art is shown in FIG DE 298 14 354 U1 disclosed.
  • the output shaft comprises a hollow shaft and a shaft insert, the shaft insert being insertable into the hollow shaft, the shaft insert having at least one first clamping element and having at least one second clamping element, wherein the clamping elements of the shaft insert can be moved from a first spatial arrangement into a second spatial arrangement by relative displacement transversely to the axis of rotation of the hollow shaft, the shaft insert being movable in the first spatial arrangement in the hollow shaft and the shaft insert being movable in the hollow shaft the second spatial arrangement in the hollow shaft is fixed in a non-positive and / or positive manner.
  • the door drive can be easily and flexibly adapted to different mounting positions with a length-adjustable output shaft. Furthermore, on the other hand, a play-free connection between the shaft insert and the hollow shaft can thereby be achieved in a particularly simple and cost-effective manner, see above that a power transmission from the door drive via a power transmission element to the door to be driven is also as free of play as possible.
  • a relative displacement of the clamping elements to one another transversely to the axis of rotation of the hollow shaft describes a displacement of at least one of the clamping elements along a direction that is not parallel to the axis of rotation of the hollow shaft.
  • This shift can run at an angle different from zero degrees to the axis of rotation of the hollow shaft, in particular, but not according to the invention, the shift can be perpendicular to the axis of rotation of the
  • the force transmission element can preferably have a scissor linkage or a slide rail linkage.
  • the clamping elements of the shaft insert can be moved from the second spatial arrangement into the first spatial arrangement by relative displacement transversely to the axis of rotation of the hollow shaft with respect to one another. This ensures that the fixing of the shaft insert in the hollow shaft is reversible. Thus, if necessary, for example for maintenance or repair, the shaft insert can be moved in the hollow shaft or removed from the hollow shaft.
  • the shaft insert is steplessly displaceable in the hollow shaft when the clamping elements are in the first spatial arrangement. This ensures that the length of the part of the shaft insert protruding from the hollow shaft can be adjusted extremely flexibly to different lengths.
  • the shaft insert has a length of at least 40 mm, preferably at least 50 mm and particularly preferably at least 70 mm. This ensures that the door drive is also suitable for assembly positions that require a relatively long extension of the shaft.
  • the shaft insert has a first engagement element, in particular with an engagement for a tool, wherein the clamping elements can be moved from the first spatial arrangement into the second spatial arrangement by adjusting the engagement element, the first engagement element in particular by a Screw, preferably an expansion screw is formed.
  • the shaft insert has a second engagement element, in particular with an engagement for a tool, the clamping elements from the second spatial arrangement into the first by adjusting the engagement element Spatial arrangement can be moved, the second engagement element being formed in particular by a screw, preferably an expansion screw.
  • first engagement element and the second engagement element are formed by a single engagement element, the individual engagement element being formed in particular by a screw, preferably an expansion screw. This ensures that both the moving of the clamping elements from the first spatial arrangement into the second spatial arrangement and the moving of the clamping elements from the second spatial arrangement into the first spatial arrangement can be carried out by adjusting a single engagement element.
  • the shaft insert has a cover sleeve, the cover sleeve at least partially surrounding the part of the shaft insert protruding from the hollow shaft.
  • This ensures that the visible part of the output shaft has a visually particularly pleasing outer contour. This also ensures that the shaft insert is protected from contamination and mechanical influences, in particular vandalism.
  • this outer contour can be designed independently of the shaft insert.
  • the cover sleeve can be made from a different material than the shaft insert and / or have a different color and / or have a different surface quality.
  • the hollow shaft and / or the shaft insert has at least one holding element, the holding element or the holding elements fixing the shaft insert in a non-positive and / or form-fitting manner in the hollow shaft when the clamping elements are in the first spatial arrangement.
  • the holding force of the holding element is selected such that the holding element is able to hold at least the dead weight of the shaft insert, in particular at least the dead weight of the shaft insert and a force transmission element.
  • the holding force of the holding element is selected such that the shaft insert can be moved manually, preferably continuously, in the hollow shaft when the clamping elements are in the first spatial arrangement.
  • the holding element is formed by an elastic ring, in particular made of rubber, the ring in particular being arranged in a circumferential groove in one of the clamping elements.
  • the clamping element can be manufactured particularly cost-effectively and can be easily integrated into the output shaft.
  • the length of the shaft insert is greater than the length of the hollow shaft, in particular the length of the shaft insert being less than 300%, preferably less than 200%, particularly preferably less than 150% of the length of the Hollow shaft. This means that even if the hollow shaft is filled with the shaft insert over its entire length, one end of the shaft insert protrudes from the hollow shaft. This end can then be connected to the force transmission element for power transmission between the door drive and the power transmission element.
  • the shaft insert has a non-circular outer profile and the hollow shaft has a corresponding non-circular inner profile, the non-circular outer profile of the shaft insert engaging the non-circular inner profile of the hollow shaft. This ensures that the shaft insert is reliably protected against rotation relative to the hollow shaft when it is inserted into the hollow shaft. This means that relatively high torques can also be transmitted between the hollow shaft and the shaft insert.
  • the outer profile of the shaft insert can be polygonal, for example triangular, square, pentagonal or hexagonal, the hollow shaft having a corresponding polygonal, for example triangular, square, pentagonal or hexagonal inner profile.
  • the hollow shaft has internal teeth and the shaft insert has external teeth, the external teeth engaging the internal teeth when the shaft insert is inserted in the hollow shaft. This prevents rotation of the shaft insert in the hollow shaft.
  • the door drive can in particular be arranged directly on or in the door leaf, on or in a wall, on or in a door frame or on or in the floor.
  • the door drive can in particular be selected from the group of overhead door closers, door closers mounted in the door, frame door closers or floor springs.
  • the door drive can be designed as a mechanical door drive or as a door drive operated with an auxiliary power.
  • a door closer is able to store at least part of the energy used by the person entering the door during the opening process of the door. After releasing the door leaf by the person entering the door, the door closer can use the stored energy to automatically close the door leaf again.
  • a door drive operated with auxiliary power can in particular be an electrical and / or electromechanical and / or electrohydraulic and / or pneumatic door drive, with the door leaf, i.e. by means of electrically and / or electromechanically and / or electrohydraulically and / or pneumatically generated auxiliary power, can be closed and / or opened.
  • the helper can be dimensioned in such a way that the helper has a supporting effect, that is to say that the person entering the door has to use less force when opening and / or closing the door.
  • the assistant can also be dimensioned such that the door is automatically opened by the assistant, that is to say that no personal effort has to be used by the walker in addition to the assistant.
  • the auxiliary force is preferably adjustable, in particular as a function of the opening angle of the door leaf. If the auxiliary power fails, door drives operated with auxiliary power preferably continue to perform the functions of a mechanical door drive, in particular the function of automatically closing or opening the door.
  • Door drives can preferably have at least one safety device.
  • the safety device can, for example, in particular limit the opening force and / or the opening speed.
  • the safety device can in particular monitor the swivel range of the door leaf and trigger a safety function if a person or an object comes into the swivel range of the door leaf.
  • a safety function can include, for example, stopping the door leaf, reducing the speed of the door leaf or reversing the movement of the door leaf.
  • Door drives can preferably have at least one monitoring device.
  • the monitoring device can in particular have sensors that can detect dangerous environmental conditions, such as B. fires, smoke or dangerous concentrations of gases (e.g. carbon monoxide).
  • the monitoring device can trigger a safety function after the detection of dangerous environmental conditions.
  • a safety function can include, for example, overriding an automatic door opening function.
  • the monitoring device and the safety device can be designed separately or can be formed by a common device.
  • Door drives can preferably have at least one pulse generator.
  • the pulse generator can in particular give the command to open and / or close the door.
  • the command given by the pulse generator is processed by a controller, the controller controlling the door leaf movement commanded by the pulse generator.
  • Impulse generators are divided into conscious impulse generators (e.g. switches, buttons), via which the door leaf movement is consciously initiated, and unconscious impulse generators (e.g. light barriers, radar, contact mats), via which the door leaf movement unconsciously when the impulse generator is entered monitored area is initiated.
  • door drives can preferably control or regulate the closing movement of the door leaf in such a way that the closing process can be delayed for an, in particular adjustable, time.
  • This damping function is also referred to as closing delay.
  • door drives can preferably comprise a housing.
  • the housing can preferably have a substantially cuboid shape.
  • the housing can preferably have at least one first opening for coupling the output drive arranged in the housing to a force transmission element.
