Definitions

  • the invention relates to a drive device for a building opening shading with an electric tubular motor interacting with a winding shaft and with a stationary housing part, preferably a lateral cover cap of a box accommodating the winding shaft, the tubular motor being connectable to a power source and being rotatably mountable on the housing part during operation, and with the tubular motor and the housing part assigned, non-rotatably connected or connectable therewith, facing adapters as well as a locking device and an electrical coupling, wherein the adapters can be plugged into one another in the axial direction and releasably locked to one another in the direction of rotation by means of the locking device and electrically conductive by means of the electrical coupling can be coupled to one another, with electrical coupling provided on the adapters, which can be brought into mutual contact in the axial direction, to the power source or the tubular motor electrically connected contact elements are provided.
  • a device of this type is from the EP 1 365 101 A1 known. Such a device enables the tubular motor to be connected wirelessly to the associated power source. A supply of cables to be accommodated in the box, which was previously required, is therefore not required. Nevertheless, in the known arrangement, in the event of a defect in the tubular motor when the curtain is rolled up, it is very difficult to remove the winding shaft containing the tubular motor. In the known arrangement, a plug-in pin and a plug-in sleeve that can be slipped onto this in the axial direction are provided to form the adapter, the electrical coupling being designed in the manner of an electrical connector with axial plug-in pins on the one hand and insertion openings assigned to them on the other.
  • a locking device which has a locking member designed as a cylindrical pin, which can be snapped into a hole in the plug-in sleeve under the action of a spring.
  • the winding shaft together with the tubular motor must be moved in the axial direction to such an extent that the adapter and thus the plug of the electrical coupling disengage from each other, which is very difficult when the curtain is still rolled up.
  • the same also applies if the curtain that is still wound up is to be unwound manually in this position of the winding shaft.
  • the known arrangement therefore proves to be insufficiently maintenance-friendly and maintenance-friendly.
  • this object is achieved in that at least one driver designed as a rollable round body is provided for mutual locking of the two adapters, which is received with radial mobility in an associated, radial through recess of an axial receiving sleeve of one of the adapters and one that exceeds the radial wall thickness of the receiving sleeve Has diameter and which can be brought into and out of engagement with the other adapter provided with at least one radial engagement recess for a driver by means of a rotatable locking ring arranged concentrically to the receiving sleeve, the locking ring having a receiving pocket for each driver in the area of its circumference resting on the receiving sleeve with in one direction of rotation of the locking ring at least up to the oversize of the driver compared to the radial wall thickness of the receiving sleeve increasing depth and next to it has a recess-free peripheral region.
  • the locking device is advantageously designed as a clutch.
  • the locking ring In order to release the tubular motor from the stationary component and thus release it in the direction of rotation, only the locking ring has to be actuated in the unlocking direction. After that, manual rotation of the winding shaft including the tubular motor is possible. Since no axial plug-in pins, as in the prior art, are provided, no axial movement of the winding shaft is required for this.
  • the mutual locking of the two adapters can simply be canceled by corresponding actuation of the locking ring in the unlocking direction, so that the winding shaft and motor can be rotated manually and the curtain can be unwound.
  • the winding shaft can then be easily removed and the tubular motor can be easily replaced.
  • the measures according to the invention therefore ensure a high level of servicing and maintenance friendliness with correspondingly low costs.
  • the drivers can expediently be designed as balls made of steel and the through recesses of the receiving sleeve assigned to them can be designed as bores.
  • This advantageously enables the cost-effective use of standard components from storage technology to form the drivers and simple production of the through recesses assigned to them, which simplifies and makes production cheaper and at the same time ensures a high level of functional reliability.
  • a further expedient measure can consist in providing several drivers and receiving pockets assigned to them in an odd number, the receiving pockets evenly spreading over a partial area of the inner circumference of the locking ring and those assigned to the drivers Through recesses are distributed in the same way on a portion of the circumference of the receiving sleeve. This not only enables high torques to be transmitted in an advantageous manner, but also favors the achievement of an assembly aid in such a way that the two adapters can only be plugged into one another in a desired position.
  • the adapter assigned to the tubular motor has four circumferential edges, preferably evenly distributed over its circumference, with an engagement recess being provided in the area of each edge as well as in the middle between a pair of edges and that the drivers on the receiving sleeve are arranged so that in the release position of the locking ring each driver can be moved radially outward into an associated receiving pocket of the locking ring and, in the locking position of the locking ring, at least the driver is assigned to the engaging recess provided in the middle between two peripheral edges of the adapter on the motor side, preferably all Drivers, no receiving pocket is assigned, whereby seven drivers can be provided for further perfection, two of which around the arc angle between two adjacent edges of the adapter on the motor side and the remaining ones Eils can be spaced from one another by half, and the motor-side adapter has five engagement recesses with the depth of the receiving pockets corresponding to the depth, of which four engagement recesses are assigned to its four peripheral edges and another engagement recess is provided
  • the adapter assigned to the tubular motor can be used as an axially protruding, undercut head with a circular circumference interrupted by two opposing, radial recesses and the adapter assigned to the housing part as an annular component with a radially inwardly open, circumferential receiving groove the diameter of the adapter on the motor side
  • the engine-side delimitation of said receiving groove has an insertion opening with the radially outer shape of the engine-side adapter corresponding radially inner limitation and a wall thickness corresponding to the clear width of the undercut of the engine-side adapter and the two adapters in the retracted state by one of the angular dimensions the angle corresponding to the radial recesses of the adapter on the motor side can be rotated relative to one another.
  • the gap present in the retracted state of the two adapters between the end face of the tubular motor, from which the associated adapter protrudes, and the facing end face of the housing-side adapter can be sealed by means of a sealing ring, preferably designed as an O-ring. This prevents dust and moisture from penetrating the mechanical locking device and the electrical coupling, which increases the functional reliability.
  • the adapter assigned to the tubular motor can be provided with axial contact pins that are electrically connected to the tubular motor and the adapter assigned to the housing part with contact plates electrically connected to an assigned power source and a grounded element, on which the contact pins are provided in the axial direction Plant can come. This ensures that the electrical coupling is automatically closed when the two adapters are plugged into one another and vice versa, which facilitates assembly and disassembly.
  • the contact pins of the motor-side adapter assigned to the current-carrying lines can advantageously protrude in the axial direction into its undercut, and the assigned contact plates of the housing-side adapter Adapter to be arranged on the inside of the motor-side delimitation of its receiving groove.
  • the contact pin connected to the grounding line from the tubular motor can protrude opposite the axial face of the motor-side adapter and the assigned contact plate can be designed as a circumferential ring which is embedded in the front boundary of the receiving groove of the housing-side adapter in the retraction direction of the motor-side adapter and the assigned housing part contacted.
  • the ring-shaped configuration of the contact plate provided for grounding results in a sliding contact which ensures reliable grounding and thus a high level of safety in every rotational position of the adapter on the motor side and accordingly also when manually unwinding a curtain.
  • the contact pin assigned to the grounding line and the contact plate assigned to it can advantageously be arranged offset radially inward relative to the other current-carrying contact pins provided for flow and return as well as a neutral conductor and the contact plates assigned to them. This favors a compact design.
  • Another favorable measure can be that the locking ring is acted upon in the locking direction by means of a swivel spring and can be rotated into its release position counter to the spring force by means of an actuating bracket that engages a radial arm of the locking ring. This ensures that the locking device is automatically brought into the locking position and can only be unlocked manually, which ensures a high level of functional reliability.
  • a further advantageous measure can be that the housing part is provided with a bearing pin onto which the adapter assigned to the tubular motor can be plugged and which passes through the adapter assigned to the housing part, which can be supported in the direction of rotation on a torque support that is non-rotatably supported on the housing part Bearing plate is formed and that the housing part with an associated adapter including torque support covering deflector plate is provided.
  • the bearing journal of the housing part can advantageously absorb the transverse forces, so that the interengaging adapters are relieved of this, which ensures a high level of functional reliability.
  • the invention is suitable for all types of building opening shading devices with a curtain that can be wound onto a winding shaft, such as roller shutters, textile screens, etc.

  • the contact elements on both sides come into contact, which results in an electrically conductive connection between the tubular motor 5 and an associated power source. Since the contact elements on both sides are hard-wired to the tubular motor 5 or the power source and come into contact when the two adapters 6, 7 are plugged together, i.e. are electrically coupled, there is no need for a cable bridging the joint between the faceplate cap 2 and the tubular motor 5 accommodated thereon.
