Definitions

  • the present disclosure relates to a support unit for non-rotatably receiving a drive unit for a closure or protective device, with a holding piece that has a receiving profile, and with a connecting piece that is adapted to the receiving profile and that can be connected to a drive unit.
  • Such a drive unit forms, for example, part of a shaft assembly for roller shutters, awnings or the like.
  • the present disclosure relates to such drive units that are integrated into the shaft assembly and, in particular, are arranged coaxially with the shaft assembly.
  • the present disclosure relates to a closure or protection device, in particular a roller shutter, a roller shutter or an awning, with a first support, a second support and a shaft assembly which is accommodated on the first support and on the second support.
  • the present disclosure relates to a method for tool-free deactivation of an anti-rotation device for a drive unit of a locking or protective device.
  • locking or protective devices should not be understood to mean that a corresponding device must serve either for locking purposes or for protective purposes. It goes without saying that, for example, roller shutters or roller shutters can very well serve both as a locking device and at the same time as a protective device. With an awning, the function as sun protection or weather protection regularly comes to the fore. On the one hand, the term protection can include protection against environmental influences. Furthermore, at least in some embodiments, this can also be understood as protection against unwanted intrusion (theft protection).
  • a roller shutter box with a roller shutter curtain which can be wound up on an armored shaft therein, the armored shaft being accommodated between two bearing elements which are each rotatably mounted in the roller shutter box.
  • a tank base plate is provided with a disk-like body that carries a bearing element.
  • the base body is held on a guide profile designed as a C-guide, which is provided with locking lugs.
  • an arrangement for mounting a roller shutter is known, with an adapter plate, which comprises an essentially circular plate and one or more radially outwardly protruding projections, and with a ring-like retaining element with one or more openings on its end face, the adapter plate and the Retaining element are designed such that the adapter plate can be inserted axially into the retaining element by aligning the one or more projections of the adapter plate with a corresponding opening in the front cover of the retaining element.
  • the adapter plate is then rotated by a small angular amount relative to the holding element. This also protects the adapter plate against further twisting.
  • a locking element is provided which can engage in the adapter plate in a specific rotational position in order to hold it in a rotationally fixed manner.
  • Shaft assemblies of the type described herein may also be referred to generically as a retractor and are usually intended to controllably wind or unwind a closure unit in the form of a so-called armor which has various members to cover or uncover an opening.
  • An installation dimension for the shaft assembly is usually through the existing opening (window, door or the like) as well as through corresponding clearances in the wall and / or specified by given dimensions of a box.
  • An installation dimension for the shaft assembly is usually through the existing opening (window, door or the like) as well as through corresponding clearances in the wall and / or specified by given dimensions of a box.
  • the shaft assembly can be assembled in a partially or completely unwound state, so that the hollow profile body is at least partially (radially) accessible.
  • the armor is wrapped around the hollow profile body.
  • the hollow profile body is not accessible.
  • a defect can occur in a partially or fully wound state of the closure or protection device.
  • the armor would have to be unwound, for example, in order to gain access to the drive unit.
  • Shaft assemblies are typically received at a first bearing and a second bearing.
  • One of the two supports also serves as a torque support or motor mount for the drive unit.
  • an electric motor of the drive unit is supported on the frame via one of the two supports, so that a relative movement of an output of the motor and overall of the hollow profile body with the armor can take place in relation to the frame, i.e. a wall or a roller shutter box.
  • the entire shaft assembly often has to be turned relative to the box or the wall together with parts of an engine bearing fixed to the housing in order to carry out a manual unwinding process, so to speak.
  • the shaft assembly can then be exposed allowing access to the drive unit.
  • the present disclosure is based on the object of specifying a support unit for the non-rotatable accommodation of a drive unit of a shaft assembly for a locking and protective device, which is easy to assemble and which, in the event of a defect in the drive unit, can be deactivated with little effort and, if possible, without tools.
  • a state of the shaft assembly of the locking or protective device should be brought about with as little effort as possible, in which manual unwinding (or winding up) of the shaft assembly is made possible, bypassing the torque support of the drive unit. This is preferably also possible when direct radial access to the support unit is not possible.
  • the support unit should be designed in such a way that simple and low-error/error-free assembly is made possible.
  • a closure or protection device which comprises a first bearing and a second bearing and a shaft assembly which is received on the first bearing and on the second bearing, wherein at least one of the two supports is designed as a support unit according to the present disclosure.
  • the present disclosure is based on the object of specifying a corresponding method for tool-free deactivation of an anti-rotation device for a drive unit of a locking or protective device.
  • the object of the invention is achieved by a support unit according to claim 1
  • the support unit can be switched between two states by a relative movement, in particular a relative movement in a plane that is perpendicular to a longitudinal axis of the drive unit.
  • the connecting piece In the first state, in which the connecting piece is arranged in the first receiving position, the connecting piece can rotate relative to the holding piece. It is thus possible in this state to rotate the entire drive unit, if necessary the entire shaft assembly, relative to the holding piece and thus relative to a receiving box or a receiving wall. In this way, for example, a tank or a length of fabric can be unwound or wound up manually.
  • the connector In the second state, the connector is in the second receiving position. In the second recording position is no relative rotation between the connecting piece and the holding piece.
  • a torque support for the drive unit is provided so that the drive unit can drive the shaft assembly, in particular a hollow profile body of the shaft assembly, in a defined manner in order to open or close the locking or protective device by motor.
  • the second receiving position or the second state therefore basically correspond to a normal operating state.
  • the first receiving position or the first state therefore basically corresponds to a maintenance state or a state in which the shaft assembly can be rotated manually from the outside, bypassing a torque support of the drive unit.
  • connection piece there is a form-fit positional securing for the connection piece by the holding piece in the second receiving position.
  • the connecting piece can usually be connected to a motor housing or to a motor frame of the drive unit. It is also conceivable to integrate the connecting piece in such a motor housing or motor frame of the drive unit. At least in the second receiving position, the connecting piece and the holding piece provide a rotation lock or torque support for the drive unit.
  • the connecting piece or the drive unit coupled to the connecting piece can be rotated about a longitudinal axis of the drive unit or the shaft assembly.
  • the transition from the second state to the first state can be brought about by a movement of the connecting piece relative to the holding piece. This movement causes the longitudinal axis of the shaft assembly to tilt or offset slightly. In any case, this is the case if the other support of the locking and protective device, which is remote from the support unit, remains in its original position or its original state.
  • the first recording position can also be referred to as the maintenance and dismantling position.
  • the first pickup position and the second pickup position enable a total of two defined bearing states for the drive unit/shaft assembly relative to the surrounding box or to the surrounding wall.
  • Switching between the first receiving position and the second receiving position can preferably take place without tools. This has the advantage that, even in the case of a very limited installation space, it is possible to deactivate the anti-twist device provided in the second state. Equally, activation can also be brought about without tools, in that the connecting piece snaps into place in the second receiving position on the holding piece. Preferably, no loosening and/or attachment of separate securing elements in the form of securing rings, cotter pins or the like is required for the activation or deactivation of the anti-twist device.
  • the connecting piece can also be referred to as the end cap of the drive unit.
  • the connecting piece is usually arranged on a front end of the drive unit, which faces the support unit.
  • the holding piece and the connecting piece are designed as plastic parts, in particular as injection molded parts. This simplifies production and avoids costly post-processing. In addition, various functions can be integrated without the need for additional components.
  • at least the holding piece or the connecting piece is designed in one piece.
  • the holding piece and the connecting piece are each designed in one piece.
  • the connecting piece can be moved between the first receiving position and the second receiving position in the receiving profile, overcoming a constriction that causes the holding force.
  • This has the advantage that the first recording position and the second recording position can be clearly distinguished from one another.
  • the constriction can be provided by the holding piece itself or by the receiving profile.
  • the constriction can be formed in particular by wall sections of the receiving profile.
  • a recess on a base plate of the holding piece is assigned to the constriction of the receiving profile.
  • a certain deformability is provided for the receiving profile in the area of the constriction, so that it is possible to deviate in order to let the connecting piece pass through the constriction.
  • the connecting piece is moved between the first receiving position and the second receiving position parallel to a base plate of the holding piece and/or in a plane perpendicular to a longitudinal axis of the drive unit.
  • the longitudinal axis of the drive unit is defined approximately by the longitudinal axis of the hollow profile body (winding body) or by the axis of rotation of the drive unit.
  • This design enables the transition between the first receiving position and the second receiving position even when the shaft assembly is received under axial preload on the first bearing and on the second bearing. In other words, it is not possible, or only possible with great effort, to detach the connecting piece axially from the holding piece. Instead, it is proposed to use a radial movement or an approximately radial movement for switching between the first state and the second state.
  • the movement of the connecting piece between the first receiving position and the second receiving position is brought about by an external force acting on the drive unit, in particular by a radially acting tensile force or compressive force.
  • an assembler can push or pull the shaft assembly near the bearing unit in a defined direction to move the link between the second receiving position and the first receiving position.
  • this force can be applied even when the shaft assembly is partially or fully wound. There is no need to apply force directly to the connector. Furthermore, it is not necessary to reach the connector with a tool.
  • a transition from the first receiving position to the second receiving position is only possible with a specific rotational orientation of the connecting piece in relation to the holding piece.
  • the connecting piece can basically be rotated relative to the receiving profile of the holding piece.
  • the connecting piece in the first receiving position can be axially fed to the holding piece or axially detached from the holding piece, and the connecting piece is received in the second receiving position in an axially secured position on the holding piece.
  • the first receiving position not only serves to deactivate an anti-twist device for manual winding or unwinding of the shaft assembly.
  • the first receiving position for the connecting piece also enables the shaft assembly to be mounted (and, if necessary, dismounted) on the support provided with the support unit.
  • the receiving profile deforms in sections when the connecting piece is moved between the first receiving position and the second receiving position.
  • the deformation occurs in particular in the area of the constriction.
  • the receiving profile is preferably designed in such a way that the deformation is reversible.
  • the mounting profile is designed to be sufficiently elastic, at least in the area of the constriction. The deformation does not result in damage to the receiving profile that would limit its function.
  • the connecting piece has an annular surface or annular section surface which has a Outer diameter defined. In this way there is a bearing surface or sliding surface for the connecting piece on the receiving profile. Overall, the connecting piece is designed approximately like a disk.
  • the receiving profile has an annular surface or annular section surface at least for the first receiving position, preferably for the first receiving position and the second receiving position.
  • the ring surface or ring section surface of the receiving profile is adapted to the ring surface or ring section surface of the connecting piece.
  • the constriction defines a distance or passage which is smaller than the outer diameter of the connecting piece.
  • the distance is only slightly smaller than the outer diameter, so that the connecting piece can overcome the constriction by deforming the receiving profile in the area of the constriction.
  • the receiving profile viewed from the drive unit, is designed in the shape of an eight or slotted hole and is provided with a central constriction.
  • the receiving profile has corresponding recesses which form the first receiving position and the second receiving position for the connecting piece designed like a disk.
  • the connecting piece with corresponding recesses, with the receiving profile defining a disk-like projection.
  • Essential design goals of the present disclosure can also be achieved with a design that accordingly has a reverse assignment of the individual elements of the support unit.
  • the receiving profile forms a first center and a second center, the first center defining the position of the connecting piece in the first receiving position, and wherein the second center defines the location of the connector in the second receiving position.
  • a guide profile is formed on the holding piece, which in the second receiving position or in the second state is coupled to a counter-profile on the connecting piece such that the connecting piece is held on the holding piece in a rotationally secure manner.
  • the guide profile is formed on a base plate of the holding piece.
  • the guide profile has a main extension direction, which is, for example, radial to the longitudinal axis.
  • the guide profile defines the direction in which the connector has to be moved in order to move the connector from the second pick-up position to the first pick-up position.
  • the guide profile is designed as a raised guide profile.
  • the counter-profile is designed, for example, as a groove on the connecting piece.
  • the counter-profile is formed on the end face of the connecting piece that faces the receiving profile.
  • the guide profile and the counter-profile work together in order to fasten the connecting piece to the holding piece in a torsion-proof manner.
  • the guide profile is contacted by an end face of the connecting piece.
  • the guide profile has a main extension direction that is parallel or essentially parallel to a movement path for the connecting piece between the first receiving position and the second receiving position.
  • the guide profile is interrupted in sections. This has the advantage that, overall, there is a sufficiently large guide length for the connecting piece in the second state. In this way, a high torque can be absorbed.
  • the guide profile has a first section and a second section which are spaced apart from one another, with the Connector has a recess surrounding the first portion in the first receiving position, so that the connector is rotatable about the first portion of the guide profile.
  • the first section of the guide profile is assigned to the first receiving position for the connecting piece.
  • the first section of the guide profile is arranged in the first center of the receiving profile.
  • the connecting piece can rotate about the first section of the guide profile.
  • the corresponding recess on the connector, provided in the center of the connector allows this rotation.
  • the counter-profile moves the connecting piece into the guide profile on the holding piece.
  • the counter-profile on the connecting piece is also interrupted, with a first section and a second section being provided, and with one of the two sections in the engaged state in the second receiving position of the connecting piece with the first section of the guide profile and another section with the second Section of the guide profile is coupled.
  • the first center and the second center of the receiving profile which define the first receiving position and the second receiving position, are spaced apart from one another by a distance which is less than half the outer diameter of the connecting piece. This ensures that the connecting piece can still contact the first section of the guide profile in the second receiving position, with the first section of the guiding profile being arranged in the first center at the same time, so that the connecting piece in the first receiving position moves around the first section of the guide profile can turn.
  • the second section of the guide profile engages in the counter-profile of the connecting piece only in the second receiving position. This also applies in principle to the first section of the guide profile, it being possible for the first section of the guide profile to be covered by the connecting piece (at the front) in the first receiving position.
  • two or more counter-profiles are formed on the connecting piece, which preferably intersect in a center of the connecting piece.
  • the connecting piece can move into the second receiving position in a plurality of rotational positions relative to the holding piece.
  • the counter-profiles on the connecting piece extend radially on an end face of the connecting piece that faces the holding piece. For example, it is conceivable to form two counter-profiles offset from one another by 90° on the connecting piece, each of which completely penetrates the connecting piece radially. In this way, there are a total of four receiving positions offset by 90° for coupling to the guide profile for the connecting piece.
  • corresponding insertion aids or insertion bevels can be formed on the guide profile and/or on the counter-profile in order to simplify the coupling process.
  • a form-fitting axial positional securing for the connecting piece is provided in the second receiving position.

  • the purpose of securing the axial position is in particular to prevent the connecting piece from being lifted off the holding piece, at least in the second receiving position.
  • the guide profile and the counter-profile not only work together to prevent rotation/torque absorption.
  • the at least partially undercut design also allows protection against undesired axial lifting.
  • guide profiles are also conceivable that are designed in a way that differs from a dovetail guide. If such guides also prevent lifting and ensure adequate protection against rotation, their use is also conceivable.
  • the guide profile and the counter-profile assigned to it bring about a form-fitting axial positional security, it is nonetheless conceivable to provide the guide profile and the counter-profile with a sufficiently large joint play. In this way, tolerance compensation is made possible. In particular, it is not about highly accurate guidance.
  • the guide profile and the counter-profile primarily work together in order to prevent an undesired twisting of the drive unit relative to the holding piece.
  • the main objective is primarily to prevent loss.
  • embodiments are conceivable that are provided with a correspondingly large amount of play. In particular, this facilitates assembly and the transition between the first state and the second state.
  • the receiving profile is provided with a retraction locking arrangement which prevents incorrect positioning due to the mating profile engaging in a wall section of the receiving profile.
  • the drive-in lock arrangement can include a design in which a corresponding side wall of the receiving profile is designed to be sufficiently wide, in particular wider than the counter-profile on the connecting piece.
  • An alternative embodiment of the drive-in lock arrangement includes a double wall in the lateral area of the receiving profile in order to define a sufficient distance between the two walls that is greater than the width of the counter-profile.
  • the holding piece is provided with an assembly aid in the form of a ramp which is formed on a base plate of the holding piece, the assembly aid facilitating engagement of the connecting piece in the receiving profile.
  • an assembly aid with a ramp now allows the shaft assembly provided with the connecting piece to be joined to the holding piece, with the shaft assembly being gradually subjected to axial loading or compression. In this way, the receiving profile on the holding piece can be overcome "from the outside".

  • step S18 which includes moving the connecting piece into a second receiving position on the holding piece, cf. 15 .
  • the connecting piece and thus also the drive unit are secured against rotation holding piece fixed.
  • a torque support for a motor of the drive unit of the shaft assembly is thus provided.
  • steps S16 and S18 ie the transition between the first receiving position and the second receiving position
  • the connecting piece it is also necessary for the connecting piece to assume a defined rotational position in relation to the receiving profile on the holding piece. Only in such a rotational orientation is it possible for a guide profile on the holding piece and a counter-profile on the connecting piece to engage in one another. In the second receiving position of the connecting piece, an anti-twist device is effected via the guide profile and the counter-profile.
  • an exemplary embodiment of a method for dismantling a shaft assembly is illustrated using a schematically greatly simplified block diagram, which includes deactivating an anti-rotation device of a drive unit of the shaft assembly.
  • a force is applied to a connecting piece of a bearing unit.
  • this can be done without tools.
  • the force can be applied indirectly to the connecting piece by acting on the shaft assembly, in particular on a hollow profile body of the shaft assembly.
  • a force is usually applied radially or essentially radially to a longitudinal axis of the shaft assembly or the connecting piece.
  • step S52 the connecting piece and thus the shaft unit are moved from a second receiving position into a first receiving position on a receiving profile of the holding piece, with a constriction being overcome.
  • the connecting piece In the first receiving position, the connecting piece can be rotated relative to the receiving profile and thus relative to the holding piece. In this way, an unwinding process can be carried out in a further step S54. In this way, access to the drive unit is made possible in order to carry out repairs, inspections or the like.
  • step S56 This can be followed by a step S56, which relates to the dismantling of the shaft assembly, which was previously held on the support unit in a torsion-proof manner, with this preferably also including an axial position securing. Dismantling can be made possible, for example, by at least slight axial compression of the shaft assembly. The (axial) length expansion can be reduced at least temporarily, so that a complete disengagement from the first receiving position of the holding piece is also made possible.
