Definitions

  • the invention relates to a door drive with a housing and at least one regulating valve for adjustably regulating a fluid flow within the door drive.
  • the invention further relates to a method for producing a door drive.
  • the invention further relates to a method for adjusting the regulation of a fluid flow within a door drive.
  • Door operators known from the prior art have at least one regulating valve for adjustably regulating a flow of fluid within the door drive.
  • the fluid to be regulated is usually a hydraulic oil.
  • the regulating valve in this case regulates the fluid flow, for example by the regulating valve influencing the cross-sectional area of a fluid channel at at least one section of the fluid channel.
  • a typical field of application are damping functions for damping the movement of the door leaf operatively connected to the door drive.
  • the setting of the regulating valves of a door drive is usually in the final assembly position, d. H. when the door operator is operatively connected to the door. This is necessary because a presetting of the regulating valves is not useful due to the large number of different doors with correspondingly different properties.
  • a factory adjustment of the door drive to a special door variant is undesirable from a production point of view, since it is much cheaper to produce as few variants of a door drive.
  • Door operators from the group of overhead door closers can be mounted with their housing both on the door leaf and on the door frame, on the door frame or on the wall in which the door is embedded. Furthermore, a distinction is made between the mounting on the hinge side or the tape opposite side, as well as the mounting on DIN left doors or DIN right doors.
  • a group of known from the prior art door drives has the disadvantage that at least two variants of the door drive must be made to cover all possible combinations of the previously described installation variants, as is not guaranteed with only one variant that in each case the regulating valves for setting the regulation are accessible to an operator.
  • Alternative door drives from the prior art come with a variant of the door drive to cover all possible combinations of the previously described mounting variants, but have limited functionality.
  • these door drives are not functional over a door opening angle of at least 180 °, since these door drives must use a symmetrical Hubkurvenin, instead of an asymmetric Hubkurveninflammatory to reduce the number of variants from two to one.
  • a door drive which is suitable for several mounting positions and inexpensive. Furthermore, it is the object of the invention to provide a method for producing a door drive, which enables the production of a door drive in a cost effective and simple manner. It is a further object of the invention to provide a method of adjusting the regulation of fluid flow within a door operator which allows the adjustment of the regulation of fluid flow within a door drive in a simple manner.
  • the previously derived and indicated object is achieved on the basis of the door drive described above in that the door drive for a regulating valve or at least one of the regulating valves has an associated attack element and an associated gear, wherein the attack element has at least two attacks, in particular for a tool in that the engagement element extends through the housing such that the attacks can be operated from outside the housing and the transmission converts a movement of the engagement element into an adjustment of the associated regulating valve.
  • the attack element has at least two attacks, in particular for a tool in that the engagement element extends through the housing such that the attacks can be operated from outside the housing and the transmission converts a movement of the engagement element into an adjustment of the associated regulating valve.
  • the regulating valve or the regulating valves are better protected against damage, since they are adjusted only indirectly via the respective associated attack element and the respective associated gear and not directly, manually or with tools adjusted.
  • the regulating valve or valves may also be made from less robust but less expensive materials, such as plastic or die-cast zinc.
  • the transmission ratio can in particular be chosen so that a movement of the engaging element is converted into a relative to the movement of the engaging element smaller adjustment of the regulating valve. This is a relief to the operator, since in this case lower accuracy and / or lower force is required in the operation of the attack.
  • the door drive may 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 may in particular be selected from the group of overhead door closers, door closers mounted in the door, the frame door closers or the floor door closers.
  • the door drive can be designed as a mechanical door drive or as an auxiliary power operated door drive.
  • a door closer is capable of storing at least a portion of the energy used during opening of the door by the door opener. After the door has been released by the user, the door closer can use the stored energy to automatically close the door leaf again.
  • An auxiliary door drive may be, in particular, an electromechanical and / or electrohydraulic and / or pneumatic door drive, whereby the door leaf, ie by means of an electromechanically, electrohydraulically and / or pneumatically generated auxiliary power, can be closed and / or opened.
  • the auxiliary power can in this case be dimensioned such that the auxiliary power acts as a support, d. H. that the user has to expend a reduced own power when opening and / or closing the door.
  • the auxiliary power can also be dimensioned such that the door is automatically opened by the assistant, d. H. that no intrinsic force has to be expended by the user in addition to the assistant.
  • the auxiliary power in particular as a function of the opening angle of the door leaf, adjustable.
  • auxiliary door drives preferably continue to fulfill the functions of a mechanical door drive, in particular the function of automatically closing the door.
  • Door drives preferably have at least one safety device.
  • the safety device can in particular limit the opening force and / or the opening speed.
  • the safety device can monitor the swiveling range of the door leaf and trigger a safety function when a person or an object gets into the swiveling range of the door leaf.
  • a safety function may include, for example, stopping the door leaf.
  • Door drives preferably have at least one monitoring device.
  • the monitoring device may in particular have sensors that can detect dangerous environmental conditions, such. As fires, smoke or dangerous concentration of gases (eg carbon monoxide).
  • the monitoring device can trigger a safety function after the detection of dangerous environmental conditions.
  • a security feature may include overriding an automatic opening function of the door.
  • the monitoring device and the safety device can be designed separately or be formed by a common device.
  • Door drives 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 pulser is processed by a controller, with the controller controlling the door leaf movement commanded by the pulser.
  • Pulse encoders are differentiated into conscious pulse generators (eg switches, pushbuttons), through which the door leaf movement is intentionally introduced, and unconscious pulse generators (eg light barriers, radar, contact mats), over which the door leaf movement is unconsciously initiated upon entering an area monitored by the pulser.
  • door drives can control or regulate the closing movement of the door leaf in such a way that the closing process can be delayed for a, in particular adjustable, time.
  • This damping function is also referred to as closing delay.
  • the housing is formed substantially cuboid. On the housing decorative elements may be arranged which cover parts of the housing or even the housing substantially completely.
  • the housing is preferably made of a material.
  • the housing may be made of a metallic material. It is further preferred that the housing is formed in one piece.
  • the housing can be formed by several sections.
  • the housing may be at least partially made of plastic.
  • the attacks of the attack element or the attack elements are arranged such that in each mounting position of the door drive at least one attack per attack element is accessible to an operator. This ensures that in any mounting position each regulating valve is adjustable.
  • the attacks of the engagement element or at least one of the engagement elements are arranged on at least two different sides of the housing. Furthermore, it can be provided that the attacks of the attack element or at least one of the engagement elements are arranged on two opposite sides of the housing. For example, in a parallelepiped housing and an attack element with two attacks, an attack on the top of the housing and an attack on the bottom of the housing may be arranged or an attack on the back of the housing and an attack on the front of the housing or an attack on one end face of the housing and an attack on the other end face of the housing may be arranged.
  • the one engagement element or at least one of the several engagement elements has a shaft. This ensures that the attack element or the attack elements are produced, for example, by milling from one piece.
  • the one engagement element or at least one of the plurality of engagement elements is designed in several parts, in particular in two parts. This ensures that the engagement element, for example, is easy to produce from different materials. In particular, the attacks of a robust material, such as metal and the remainder of the engagement element can be made of a different material. Furthermore, it can be provided in this case that the individual parts of a multi-part attack element are independently movable and the associated gear converts a movement of a portion of the multi-part engagement element regardless of the movement of another part of the multi-part attack element in an adjustment of the associated control valve.
  • the one engagement element or at least one of the plurality of engagement elements runs in a bearing or thread. This ensures that the one attacking element or at least one of the attacking elements is securely guided in the housing. Furthermore, this can be used to control the frictional forces acting on an engagement element. Furthermore, by a bearing or thread, the degrees of freedom of movement of the guided in the bearing or thread engagement element to be controlled. For example, is determined by the slope of such a thread, the offset of the guided in the thread engaging element per revolution of the engaging element.
  • the one transmission or at least one of the plurality of transmissions interacts with the associated engagement element in such a way that the associated regulating valve can not be moved further in the direction of the closed position when it reaches its closed position.
  • This ensures that the regulating valve is safely protected against harmful overadjustment.
  • this can be dispensed with a stop to limit the adjustment of the regulating.
  • the engagement element may have an end position which it reaches when reaching the closed position of the regulating and in this end position in a freewheel, wherein the engagement element in the freewheel can be moved by the operator continues, but the movement of the engagement element not in an adjustment of the regulating is implemented.
  • the one transmission or at least one of the plurality of transmissions has an eccentric arranged on the associated engagement element, wherein the eccentric is in operative connection with the associated regulating valve. This ensures that the movement of the engaging element is reliably transmitted to the associated regulating valve.
  • the one transmission or at least one of the plurality of transmissions has a worm and a worm wheel engaging in the worm. This ensures that the movement of the engaging element is reliably transmitted to the associated regulating valve.
  • the one transmission or at least one of the plurality of transmissions has a toothed rack and a toothed wheel engaging in the toothed rack. This ensures that the movement of the engaging element is reliably transmitted to the associated regulating valve.
  • the one transmission or at least one of the several transmissions has a lever mechanism, in particular a rocker. This ensures that the movement of the engaging element is reliably transmitted to the associated regulating valve.
  • the longitudinal axis of the one regulating valve or at least one of the several regulating valves runs essentially perpendicular to the longitudinal axis of the associated engaging element. This ensures that the movement of the engaging element is reliably transmitted to the associated regulating valve.
  • the longitudinal axis of the one regulating valve or at least one of the several regulating valves runs essentially parallel to the longitudinal axis of the door drive. This ensures that the space within the door drive is used optimally possible.
  • the longitudinal axis of the door drive can in this case be defined by the longitudinal axis of an energy accumulator arranged in the door drive, wherein the energy accumulator can be formed in particular by a spring, preferably a helical compression spring.
  • the regulating valves are arranged in a common bore. This ensures that the number of holes to be provided in the door drive is reduced. As a result, the production cost is further reduced.
  • the regulating valves arranged in the one hydraulic channel can in this case regulate two independent fluid flows.
  • the housing has at least one regulation module, wherein in the regulation module or in each of the regulation modules the one engagement element or at least one of the engagement elements is arranged. This ensures that the Reguliermodul can be made separately from the rest of the housing.
  • the one regulating module or at least one of the plurality of regulating modules is fastened to the remaining housing in particular detachably. This ensures that the engagement element and / or the transmission can be easily mounted, replaced and maintained. Further, the Reguliermodul can be pre-assembled independently of the rest of the housing, whereby the production of the door drive according to the invention is simplified.
  • the one regulating module or at least one of the several regulating modules is made of a different material than the rest of the housing.
  • the material of a Reguliermoduls be chosen such that it has the required properties for its function as Reguliermodul.
  • the Reguliermodul can be made of a low-cost material, such as plastic or zinc die-cast.
  • the one regulating valve or the regulating valves are arranged in the remaining housing. This ensures that, in contrast to the arrangement of the regulating valve in Reguliermodul, can be dispensed with a fluid seal between Reguliermodul and housing.
  • the Reguliermodul is thus substantially free of hydraulic fluid. This results in the material of the Reguliermoduls other, usually lower requirements than the material of the rest of the housing, which costs can be reduced by means of a suitable material selection.
  • a movement of the regulating valve or the regulating valves out of the housing is blocked by the regulation module fastened to the housing and / or by the associated engagement element. This ensures that the regulating valve or the regulating valves are protected in particular from falling out of the housing.
