Definitions

  • the invention relates to a mounting bracket for a door operator.
  • Door operators are used to close and/or open doors.
  • Door closers and door drives are referred to as door operators.
  • a spring accumulator is usually charged by the manual opening movement. The energy stored in this way is used to close the door.
  • the door With a door drive, the door can be opened and/or closed independently, for example by means of electromechanics or hydraulics.
  • Door operators are usually attached to the door leaf, frame, or wall.
  • Mounting plates are usually used to attach the door operators. The mounting plate is fastened to its mounting surface, i.e. the door, frame, or wall. The door operator, in turn, is attached to the mounting plate.
  • a mounting bracket for fire doors is made of EP 3 064 684 known.
  • the invention describes a mounting bracket that is used instead of a conventional mounting plate for attaching the door operator, namely a door closer or door drive.
  • the mounting bracket has at least a first mounting element and a second mounting element.
  • the mounting elements are connected to one another via at least one connecting arrangement. Under appropriate thermal stress, this connecting arrangement releases, so that the two mounting elements separate from one another.
  • the door operator is located on the side of the door facing away from the fire. By detaching the door operator from its mounting surface, the door operator is prevented from overheating, thereby preventing fluid from escaping from the door operator and igniting the fluid.
  • a mounting axis is defined on the mounting bracket to describe directions.
  • the mounting axis is parallel to the screws used to attach the mounting bracket to the mounting surface.
  • the mounting axis is perpendicular to the output axis of the door operator.
  • a longitudinal axis and a vertical axis are defined perpendicular to the mounting axis; the longitudinal axis extends horizontally in the standard installation position.
  • the two mounting elements are preferably plates or plate-shaped elements that are arranged next to one another or, in particular, inside one another to form the mounting bracket. It is particularly provided that the at least one first mounting element is attached, in particular screwed, to the mounting surface with its rear side. This mounting surface is formed by a door, frame, or wall. Accordingly, the second mounting element is connected to the door operator.
  • the second mounting element has, in particular, a front surface to which the door operator is attached, in particular screwed.
  • the second mounting element is a separate component to which the door operator is attached. Alternatively, however, the second mounting element can also be an integral part of the door operator.
  • the reverse design is also possible, according to which the at least one first mounting element is designed to receive the door operator and the second mounting element is fastened to the mounting surface.
  • the mounting bracket comprises at least one connecting arrangement.
  • one, two, three, four, five, or more such connecting arrangements are provided.
  • the connecting assembly In its holding position, the connecting assembly holds the two assembly elements together. This is achieved, in particular, by a positive locking within the connecting assembly.
  • the connecting assembly can be moved into a release position. In this release position, the connecting assembly no longer holds the two assembly elements together; in particular, the positive connection between the two assembly elements created by the connecting assembly is released.
  • Thermal activation occurs, in particular, in a temperature range of 90°C to 200°C.
  • the shape memory arrangement is designed such that activation occurs at a temperature appropriate to prevent the fluid from escaping from the door operator and subsequently igniting the fluid.
  • thermal activation involves heating the shape memory element, resulting in the transformation of the martensitic structure into the austenitic structure.
  • the shape memory element is preferably arranged at least partially in a receiving groove and/or a fully enclosed channel.
  • the receiving groove or channel is located in particular in the first mounting element. This arrangement in the receiving groove or channel enables a protected position of the relatively thin shape memory element so that, for example, the wire is not damaged during assembly of the mounting bracket.
  • the receiving groove or channel extends over at least 50% of the length of the shape memory element. This also ensures that heat is transported particularly quickly from the mounting surface to the shape memory element, allowing the mounting bracket to react as quickly as possible to a dangerous increase in temperature on the mounting surface.
  • the first mounting element comprises a base plate, which is particularly designed to rest against the mounting surface.
  • the base plate is screwed to the mounting surface, in particular via corresponding mounting holes.
  • the at least one first mounting element is integrated into the plate-shaped second mounting element and a space-optimized construction is provided.
  • the connecting arrangement comprises at least one locking element.
  • This locking element is movably arranged on the first mounting element and can be moved from its holding position to a release position.
  • the first mounting element is, in particular, the component to be screwed to the mounting surface (door, wall, or frame).
  • the locking element In the initial state, i.e., when the shape memory assembly is not thermally activated, the locking element is in its holding position, thereby holding the second mounting element. In the release position, the locking element releases the second mounting element, allowing the two mounting elements to separate from each other. This also releases the door operator from the mounting surface.
  • the movement of the locking element into its release position is effected by the shape memory arrangement, which exerts a corresponding force on the locking element of the connecting arrangement when thermally activated.
  • the shape memory arrangement is arranged and configured to move the locking element.
  • the locking element can be arranged on the first mounting element, in particular on the base plate of the first mounting element, for linear or rotational movement.
  • the locking element can be linearly movable either parallel to the longitudinal axis or parallel to the vertical axis, and thus perpendicular to the mounting axis.
  • the rotationally movable arrangement it is particularly provided that the corresponding locking axis of rotation is parallel to the mounting axis.
  • the shape memory arrangement is particularly arranged and configured to pull, rotate, or deform the locking element.
  • the deformation can be accompanied by a pulling and/or rotating movement of the locking element.
  • the two opposing locking elements with a shape memory assembly each.
  • one end of the shape memory assembly is then connected to the corresponding locking element, and the other end of the shape memory assembly is connected to the first mounting element, in particular the base plate.
  • the shape memory assemblies contract, thereby pulling the corresponding locking element into the desired release position.
  • At least two co-rotating locking elements are provided, wherein the two co-rotating locking elements are connected together with a shape memory arrangement, in particular a shape memory element, in a force-transmitting manner.
  • a shape memory arrangement in particular a shape memory element
  • both elements can be moved simultaneously with one shape memory arrangement upon thermal activation.
  • the shape memory arrangement is fastened at one end to the first mounting element, in particular the base plate, and the other end of the shape memory arrangement is connected to one of the two locking elements.
  • Force can be transmitted to the further locking element via a force-transmitting element, for example a sleeve.
  • the shape memory element preferably runs through the sleeve.
  • an end piece is arranged at least at one end, preferably at both ends, of the respective shape memory element.
  • This end piece is, in particular, an element crimped onto the shape memory element.
  • the shape memory assembly can be connected to the corresponding locking element and/or the base plate of the first mounting element, for example, by hooking it into a corresponding receiving fork.
  • the shape memory element can be connected to the corresponding element of the device by clamping or directly by a material bond (e.g., laser welding point).
  • At least one rolling element is preferably provided. Such a rolling element is located between the locking element and the first mounting element and/or between the locking element and the second mounting element.
  • the rolling element is preferably a roller (e.g., a rod) or a ball. Such rolling elements can be inserted into one of the mounting elements or the locking element without complex fastening.
  • the locking element can be mounted on the first mounting element for linear movement.
  • the locking element has at least one guide.
  • This guide is, in particular, a guide slot or a guide groove.
  • a guide extension protrudes from the first mounting element into the guide, thus ensuring the linearly movable guidance of the locking element relative to the first mounting element.
  • the guide extension can be an integral component of the base plate of the first mounting element or, for example, a screw inserted into the base plate.
  • a pivot bolt is arranged between the locking element and the second mounting element.
  • the pivot bolt is mounted in particular in a rotatable manner on the first mounting element.
  • the pivot axis is preferably perpendicular to the mounting axis; in particular parallel to the longitudinal axis or parallel to the vertical axis.
  • the swivel bolt comprises, in particular, two legs, with the swivel bolt rotation axis located between the two legs.
  • One leg of the swivel bolt engages directly or indirectly with the second mounting element in a form-fitting manner.
  • the other leg engages directly or indirectly with the locking element in its holding position. As long as the locking element is in its holding position, the swivel bolt is prevented from rotating about its swivel bolt axis, and the form-fitting connection to the second mounting element remains intact.
  • a cross element particularly in the form of a rod-shaped rolling element, can be arranged between the locking element and the pivot bolt. When the locking element is moved into the release position, this cross element is pulled out from under the leg of the pivot bolt.
  • the locking element is rotatably mounted on the first mounting element.
  • the shape memory arrangement can be connected directly or indirectly to the locking element in order to rotate the locking element about its locking element rotation axis.
  • a transmission rod is provided, which is pulled by the shape memory assembly upon thermal activation.
  • the transmission rod is preferably arranged so as to be linearly movable parallel to the longitudinal axis.
  • the transmission rod is in turn connected to the at least one rotatable locking element in such a way that the linear movement of the transmission rod is converted into a rotational movement of at least one locking element.
  • the locking element is positively connected to the second mounting element in the holding position and is designed such that it is released upon rotation of less than 360°, preferably less than 180°.
  • the locking element has a cam or other eccentric arrangement that extends perpendicular to the locking axis of rotation and establishes the positive connection with the second mounting element.
  • the rotatable locking element has, at least in a region of the circumference, a conical surface which interacts with a complementary conical surface of the second mounting element such that, upon rotation into the release position, the second mounting element is pressed away from the mounting surface by the two interacting conical surfaces; so that the door operator moves away from the mounting surface.
  • the shape memory arrangement is arranged and configured to deform the at least one locking element.
  • the locking element is deformed in particular such that the positive connection between the locking element and the second mounting element is released.
  • the deformable locking element has a U-shape or V-shape with two converging legs.
  • the shape memory arrangement preferably pulls on the locking arrangement centrally between these two legs, so that the two legs bend toward or away from each other to release the connection.
  • an inclined plane is formed between the locking element and the first mounting element.
  • the locking element moves over this inclined plane when moving into the release position, causing the locking element to move perpendicular to the mounting surface and thus exert a compressive force on the door operator.
  • the locking element can push away either the second mounting element or the door operator directly. This assists in the detachment of the door operator.
  • the connecting arrangement comprises at least one form-locking arrangement between the two mounting elements.
  • This form-locking arrangement comprises, in particular, form-locking elements that are directly connected to the first and second mounting elements or are integrally formed, which engage with one another in a form-locking manner in the holding position.
  • the second mounting element can be displaced into the release position relative to the first mounting element upon thermal activation by the shape memory arrangement, whereby the form-locking elements of the form-locking arrangement are released from one another.
  • the form-locking arrangement is arranged and designed to deform one of the two mounting elements, in particular the first mounting element.
  • the corresponding mounting element is deformable in such a way that that the form-fitting arrangement between the two mounting elements comes loose.
  • the first mounting element is preferably screwed to the mounting surface via elongated holes, so that the first mounting element can move relative to the screws via these elongated holes.
  • the mounting bracket comprises at least one release element.
  • the release element is a thermally intumescent material; for example, a swelling pad or a corresponding spring.
  • the release element is arranged such that it pushes the door operator away from the mounting surface.

  • the mounting bracket can have a thermally activated blocking element.
  • the blocking element is made, for example, of a thermally intumescent material or is a fluid-filled glass ampoule, such as those found in sprinkler systems.
  • the blocking element can also be another material that melts or deforms at a certain temperature.
  • the blocking element is arranged in such a way that it blocks movement of the connecting assembly into the release position.

Rather, the connecting arrangement 5 is formed directly by appropriate shaping of the two mounting elements 3, 4 as a form-locking arrangement 41. As Figures 26 and 27 As can be seen, the form-fitting arrangement 41 between the base plate 8 and the inner edge of the second mounting element 4 comprises a plurality of tooth-like form-locking elements which interlock to form the form-locking arrangement 41.
