Abstract

The rotating shutter for window or door openings comprises at least one rotationally lodged wing (12) which can be swung between an opened and a closed position by means of an electrical motor. In order to provide a rotating shutter which can be simply mounted and easily retrofitted, the invention foresees that the electrical motor be fixed on the wing (12). Said motor is engaged by at least one movable gearing element (44) on a reaction member (32) lodged on a side of the window or door opening in such a way that a torque is applied on the wing (12) in the direction of closing or opening.

Description

The invention relates to a shutter for window or Door openings with at least one pivoted wing, by an electric motor attached to the wing between an open and a closed position is pivotable, via at least one movable gear element at one next to the window or door opening mounted reaction member attacks such that on the wing a torque acts in the opening or closing direction.

Rotary stores are mostly opened and closed by hand. If this has to be done from the interior, it is necessary to open the window. With flower windows it is very inconvenient.

It is also known to open the wings by mechanical internal opening, which are operated with a hand crank. The drive by an electric motor is even more convenient. This eliminates both the need for Opening the windows as well as manual operation. The require most known electrical drive systems however, a lot of effort during assembly, since the motor in the Masonry (see FR-A1 26 11 798) or installed in the interior must become. This requires the wall to be breached for the drive axle, the motor or both components. In addition, a subsequent installation in the masonry is under Consideration of the existing wall thickness and the structural condition is not always possible if he has not already been taken into account in the planning phase. As a rule, when retrofitting, the existing ones are not Wall block can be used, one comes not without elaborate and disruptive assembly work that often other renovations, such as cleaning and renewing Paint, result.

From EP-A1 0 484 258 there is already a rotary shutter known according to the preamble of claim 1, in which a motor gear unit on the inner surface of the rotary shutter is attached, which pivots a lever that with the free end of one around a fixed bearing on the windowsill rotatable lever is articulated. Use the levers a relatively large range of motion the window sill, so that no flower boxes are set up there can be. Depending on the type of windowsill, too the storage of the levers with considerable installation effort be connected. In addition, the linkage disturbs when open Rotary shutters the visual impression.

The invention has for its object a rotary shutter of the type mentioned at the beginning, which deals with very low installation effort, especially without major wall breaks and if possible even using the Install and retrofit existing wall block with trunnion lets and the use of the window opening, for. B. for Flower boxes, not restricted.

The above object is achieved according to the invention by that the gear element is a gear with relative to the wing fixed axis is that with a next to the window or Door opening rotatably mounted on a pivot pin of the wing Gear is engaged.

The invention has the advantage that the wing with the attached electric motor, the narrow version, invisible from the outside, built into the wing can, forms a single, integrated component that in rational manufacturing process prefabricated in the manufacturing plant can be. The room above the windowsill will not impaired and can continue z. B. to set up can be used by flower boxes. If from the start or the straps attached to the wing at the construction site be that the existing wall block and bearing pins for Storage can be used, the assembly work is limited on the laying of an electrical line to the electric motor. A control line or is sufficient a wireless remote control if in a preferred one Embodiment of the electric motor operated with solar energy is generated by solar cells attached to the wing becomes. Of course, the solar cells can also be used on others Be attached to the building.

You get a very variable, adaptable construction, if in a preferred embodiment of the invention that is engaged with the non-rotatable Gear is an idler gear, which is driven by a on the output shaft the pinion of the electric motor can be driven and preferably on a rotatable on the journal of the Wing mounted and fixed to the wing swing arm is.

Taking into account the different diameters on-site bearing journals, if possible despite their different sizes still for storage of the new rotary shutter, it is also expedient, the rotatably held gear, the swing arm and to store a tape of the wing on a hollow shaft that is on the pivot pin of the wing is attachable. You use in in this case, the hollow shaft as an adapter, so it only needs some hollow shafts with different bore diameters, but otherwise the same form, and can otherwise be the same Use drive and gear parts for the rotary shutter.

The lathe doors are usually in the fully open position and locked completely closed position. While they can swivel when opening and closing however exposed to strong wind loads. To under in such circumstances, overloading and damage to the drive system avoiding is more preferred in others Execution of the invention in the drive train between the Electric motor and the pinion arranged a slip clutch, that at a certain maximum torque on the wing yields through external forces.

Instead of a gearbox made up of gears only, in an alternative embodiment of the invention, that the electric motor is a pinion via a flexible shaft with a fixed axis of rotation relative to the wing that with a non-rotatably mounted one next to the window or door opening Gear is engaged.

In this variant, the previously mentioned intermediate gear is eliminated, and because of the flexibility of the flexible shaft usually comes without overload clutch as a safety device out. In addition, the flexible fits Wave different positions of the pinion with respect to the Electric motor on without further ado.

It is also desirable that the lock of the wing takes place automatically in its end positions. To this Purpose is in the preferred practical implementation of the The rotary shutter according to the invention by a controllable Actuator lock bar from an outer edge of the Extendable wing and engaged with a hole in the adjacent outer edge of another wing and / or one bring stationary bracket. The controllable drive can e.g. from one the locking bar into the extended one Interlocking spring preloading position in interaction with the locking bar before switching on the Electric motor further retracting electromagnet in the wing consist. Alternatively, the movement of the Locking bar in the locking position instead of by a Spring are generated electromagnetically. Because of a power outage is unpredictable, it should definitely Interlock remain. On the other hand, care must be taken that under all circumstances, e.g. in the In the event of a fire, can also be unlocked manually. This can e.g. by means of one attached to the locking bar Handle happen, at least with the wing closed is accessible from the interior. An electrically controlled Locking of the type described above can be advantageous also with the rotary shutter drives known per se with wall drive. Your commitment However, this is particularly useful in rotary shutter drives according to the invention because the power supply to the drive too can be used to operate the lock, while with the wall-side drives, a supply cable must be put to the store.

In Fig. 1, a mounting frame 10 is pivotable with two mounted wings 12 and 14 of a rotary shutter shown. It is a pre-assembled one Element that only remains on the outside of a window opening Building needs to be attached. If there is already one conventional, manually operated rotary shutter attached was, you can the wings 12, 14 with adapted bands 16th also on the trunnion of the existing wall block instead on bearing pins 18 attached to the mounting frame 10 to store. There is also the possibility of new wall blocks to be anchored in the wall with journal 18. In the example case 1 there is the filling of the wings 12, 14 from lamellae 20. Instead, you could at least partly from solar cells or a closed or perforated plate consist of a suitable material.

Fig. 2 shows for a rotary shutter according to the invention, the retrofitted and on existing wall block with bearing journal the situation has been set up with reference to FIG. 1 on the lower trunnion of the left wing. 3, 4, 5A and 5B go into the details of storage and storage attacking electromotive swivel drive there Wing out more precisely.

It is assumed that the bearing journals 18, here with 22 designated wall blocks are. Since the bearing pin 18 is often different Have a diameter, a hollow shaft 24 is attached to them, whose bore diameter to the diameter of the Bearing pin 18 fits and the outer diameter of the Bearing and gear parts for the drive described below of the wing 12 fit. The preferably with only one hollow shaft 24, which is open at the bottom, has a lower section 26 and one of these by an annular collar 28 separate upper section 30. When assembled sits on the lower section 26 with a gear 32 a lower collar 34. The hollow shaft 24 is as well the gear 32 is held in a rotationally fixed manner relative to the bearing journal 18. The fixation can e.g. by means of a pen and a Cross bore through the collar 34, the lower section 26 the hollow shaft 24 and the bearing pin 18 take place. Of course other means, e.g. Parallel keys or Wedges for the non-rotatable mounting of the hollow shaft 24 and Gear 32 are used.

Sitting on the upper section 30 of the hollow shaft 24 in the assembled Condition, rotatable relative to this, in the example case at the free end fork-shaped band 16 and between the two fork legs one at one end with one bore matching the outer diameter of the hollow shaft 24 35 provided rocker 36. These parts are by their own weight held on the hollow shaft 24 and the bearing journal 18, but it can also be an additional one, not shown There is a safeguard against lifting off.

At the end opposite the bore 35, the Swing 36 another bore 38 through which according to Fig. 5 A from below with a offset bearing pin 40 an upper threaded section is inserted by means of a on the top of the rocker 36 nut 42 is attached to the swing arm. He carries a swivel on it mounted gear 44 which between the rocker 36 and a at the lower end of the bearing pin 40 attached hexagon bolt head 46 is held axially. The center distance of the Bores 35 and 38 and the pitch circles of the gear wheels 32 and 44 are chosen so that the gear 44 is in mesh rolls on the non-rotatable gear 32 when the rocker 36 about the central longitudinal axis of the hollow shaft 24 is rotated.

Since the gear 32 below the lower leg of the fork-shaped bands 16, but the rocker 36 above this Leg is located, the gear 44 as shown in FIG. 5 A formed with an upper collar 48 which the height of the lower leg of the band 16 or the distance between bridges the gears 32, 44 and the rocker 36.

In the hollow frame profile of the wing labeled 50 12 is approximately in the area where the band 16 is attached, an electric motor 52 installed, the cross section in the Cavity of the profile 50 fits and therefore from the outside is not visible. He drifts vertically downwards over his outstanding output shaft 54 and a slip clutch 56 a pinion 58, which with the one forming an idler gear Gear 44 is in meshing engagement. The intervention is through an L-shaped angle piece 60 (see FIG. 5 A, B), which on the one hand on the belt 16, on the other hand on the rocker 36 is screwed, secured. The bearing of the idler gear 44 on one on the central longitudinal axis of the hollow shaft 24 pivoting rocker 36, which can be fastened with simple fastening means, such as. the elbow 60, with different Distance to the band 16 can be fixed thereon the balancing of manufacturing tolerances and on-site dimensional Differences to which an adjustment is easy by choosing gears 32, 44 of different sizes can.

In Fig. 6 A, B are the storage and the drive the wing of another embodiment of a rotary shutter shown, of which only the middle one for the sake of simplicity and lower part of the sash designated 110 and a corner connector 112 is shown in its lower left corner are. The lathe has in the usual way upper and a lower laterally projecting band 114 or 116, each attached to the frame 110 and with their outer, cylindrically rounded ends on an upper or lower block 118 and 120 are rotatably mounted. in this respect the rotary shutter shown corresponds to the conventional one Construction.

In the frame 110 of the rotary shutter is on the storage side 114 - 120 one with a gear 122 to one unit connected electric motor 124 installed. The motor gear unit 122, 124 is with a vertical axis of rotation Outside of the web in a vertical section according to Fig. 6 A flanged reverse U-shaped engine mount 126, the is in turn screwed to the walls of the frame 110, the mounting screws parallel to the main plane of the Rotary shutter lie on the main surfaces of the rotary shutter no fastening screws are visible.

The U-shaped engine mount 126 has a web above. Below is its cross section through a screwed one Bearing cover 128 covered. In one with a bearing bush 130 lined bore in the bearing cap 128 is a bearing pin 132 rotatably mounted, the one with the output shaft of the gear 122 is rotatably connected. Through the bearing pin 132 extends a longitudinal bore 134 which the driveside end of a flexible shaft 136 receives. Around a rotationally fixed connection between the bearing pin 132 and the flexible shaft 136 can receive the longitudinal bore of the bearing bolt 132 and the end of the flexible shaft-136 flattened opposite or otherwise out of round have designed cross sections. Using clamping screws, which can be screwed into threaded holes 138 in the bearing bolt 132 are the connection between the flexible shaft 136 and the bearing pin 132 are axially secured. It exists in addition, the possibility of the longitudinal bore to produce in the bearing bolt 132 with a round cross section and the opposite flattened end of the flexible shaft 136 by means of the clamping screws to be screwed in at 138 to be anchored non-rotatably in the bearing bolt 132.

A little below the engine mount 126 is in the front wall of the hollow profile forming the frame 110 for the exit of the flexible shaft 136 an opening 140, the bounded by a protective frame 142, a so-called inlet tulip is. Below the opening 140 extends flexible shaft 136 outside of the rotary load to a drive pinion 144 out, in such a situation on the lower band 116 is mounted that it with a non-rotatable on the lower block 120 seated gear 146 meshes.

Because of the different dimensions of the block 118 and the unfavorable friction from metal to metal, 120 the tapes 114, 116 of the rotary shutter are not immediately open the block 118, 120 stored, but each via a reduction sleeve 148, 150 made of plastic. The inside diameter the reduction sleeve 148 is suitable for the diameter of the Bearing pin 118 selected while its outer diameter is constant and to the bearing diameter of the upper one Band 114 fits. At the lower block 120 is the hub body 152 of the gear 146 with one for the journal of the Klobens 120 matching blind hole 154 provided the Bearing journal. The rotatable connection between the Gear 146 and the bearing pin of the block 120 is through a cross pin 156 extending through both parts guaranteed. The metallic hub body 152 has one pin 158 projecting upwards, on which over the reduction sleeve 150 and the belt 116 of the lathe is stored. It there would also be an opportunity to adapt between the Bore 154 in the hub body 152 of the gear 146 and the pivot pin of the block 120 not by drilling, but instead to make by a sleeve adapted to its diameter.

The metal drive pinion 144 is non-rotatable and axial firmly on a bearing pin 160, which in turn is rotatable, but is axially fixed in a bearing block 162. The Bearing pin 160 is provided with an axial bore, in which the output side, out of round, z. B. flattened end the flexible shaft 136 is inserted. The non-rotatable connection between the flexible shaft 136 and the bearing pin 160 is guaranteed in the example by tapped holes 164 clamping screws to be screwed in. The bearing block 162 is screwed to the band 116. An adjustment the position of the bearing block 162 with respect to the band 116 of the The rotary shutter can be opened through vertical slots 166 in the bearing block 162 or in volume 116. The adjustment is necessary because the band 116 depends on the installation situation of the rotary shutter over the frame 110 must protrude outwards and the flexible shaft 136 has a certain length. For this reason it is also Pinion 144 much wider than gear 146.

Flexible shafts 136 of the type in question here are e.g. B. under the brand name DIAX from Schmid & Wezel GmbH & Co., Sinsheim available. They are similar in shape a coil spring. Since they are proportional to torsional forces react softly elastic, is a slip clutch in the Powertrain between the electric motor 124 and the pinion 144 usually unnecessary. The flexible shaft 136 takes unpredictable sudden loads. If the Rotary shutter hits an obstacle when swiveling, the engine switches off automatically.

On the side edge of the The rotary shutter in the area of the lower corner is one in FIG. 8 locking device shown attached. she consists from an electromagnet mounted in frame 110 168 which is slidable in a vertical direction in the frame guided locking bar 170 acts. It only needs during the pivoting of the rotary charge from the electromagnet 168 raised to a retracted neutral position become. In the open and in the closed end position of the rotary latch engages in the locking bar 170 a bracket attached below the rotary shutter. The locking position is also in the event of a power failure the dead weight of the locking bar 170 secured. In case of emergancy it can, however, by means of an externally accessible, with the Locking bar 170 connected handle can be raised.

It is understood that it is protected Location of the motor gear unit 122, 214 and the appearance the rotary or sliding shutter is desirable if the Drive unit completely covered in an internal cavity can be assembled. However, the invention is not limited to correspondingly deep frame profiles 110, but also applicable to flatter rotary shutters where the drive unit attached to the shop, e.g. B. in the open and / or closed state visible from the outside or inside is. Also protruding towards the surface of the rotary shutter Covers for the drive unit are possible.

It is further understood that the skilled person has a variety of possible modifications to those in the exemplary embodiments shown fastenings and bearings available stand.

9, the locking system of the wings 12, 14 is shown, that can also be used with the wings 110, 112 can. It consists of one in the upper frame profile of the left Wing 12 longitudinally mounted locking bar 62 and one in the lower frame profile of the right wing 14 locking bar 64 which can be moved longitudinally. The locking bars 62, 64 can each over the free outer edge of the Be extended out of this wing. In the in Fig. 6 shown closed position of the rotary shutter is located each in alignment with the locking bar 62 or 64 in the other wing an outwardly open bore 66 or 68, into which the extending locking bar 62 or 64 penetrates. In this way, the two wings 12, 14 in the closed position connected above and below and thereby secured in their position. To open the The locking bars 62, 64 are made of the respective other wing retracted, and then the wing in each case by means of the motor 52 in their fully open position swung open, in which the locking bars 62, 64 again be extended and in the same alignment with them in, not shown, fixed to the wall Penetrate the brackets.

The locking bars 62, 64 can e.g. each by the Force of a spring in the direction of the outwardly advanced Lock position be preloaded. The spring force can overcome by an electromagnet 70 and 72, respectively be the associated locking bar 62 and 64 temporarily from the locked position to the receiving position Retract wings. The excitation of the electromagnet 70, 72 occurs automatically when the rotary shutter drive is actuated before turning on the electric motors 62 for pivoting the wing 12, 14. If after reaching each other End position, the electric motors 52 switched off again hear the excitation of the electromagnets 70, 72 on, so that again by means of the springs, not shown Locking position of the locking bars 62, 64 made becomes. It is understood that other suitable controllable Drives for the locking bars 62, 64 come into question and that it poses no problems, at least the wing in the closed position to the interior facing side e.g. one through an elongated hole in the frame profile of the wing extending handle on everyone To attach the locking bar, which also allows you to Power failure, e.g. in the event of a fire, unlocked by hand Push back position and overcome the wings to open the slip clutch 56.
