Description

The invention relates to a drive device of a roller shutter, which can be driven both electrically and manually. Furthermore, the invention relates to a roller shutter with such a drive device.

The prior art basically knows shutters that can be powered either by an electric motor or manually. A disadvantage of the motorized shutters is that in case of power failure or if the engine is defective, the function of the roller shutter is limited. On the other hand, roller shutters, which are only manually drivable, have the muscle power of the operator. In this regard, systems are proposed in the prior art that allow manual operation of a motorized shutter. In this case, a geared motor is generally used. For example, emergency drives on hand crank are known, however, are cumbersome to use and can open the shutter only very slowly, since the strong reduction of the engine must also be operated. Furthermore, normally emergency drives, in which an energy storage element is provided for opening the shutter in case of power failure, expensive and complex. Furthermore, the operator of such a device has no control over the device during the opening of the shutter. The documents EP 2 034 126 A1 . US 2006/042765 A1 . EP 2 821 584 A1 and US 2010/132505 A1 show known drive devices for shutters.

It is therefore an object of the invention to propose a drive device of a shutter, which is compact, can be easily handled by an operator, and allows quick manual operation of the shutter.

The solution of this object is achieved by the combination of features of claim 1. According to the invention, a drive device of a roller shutter is proposed, which has a roller shutter shaft which is manually driven in a first mode via a movable part of an electric drive and in a second mode. The drive device comprises a housing, an inner part, a manually operable drive element, and a locking device. The inner part is rotatable on the housing arranged and has a receiving area for rotationally fixed receiving a non-movable part of the electric drive. Furthermore, the manually operable drive element is arranged directly on the inner part and serves for manually driving the roller shutter shaft. The locking device blocks a rotational movement of the inner part in a locked state, wherein the roller shutter shaft is driven in the first mode. After actuation of the locking device, a rotational movement of the inner part is released in the unlocked state, wherein the roller shutter shaft is driven in the second mode. By the drive device, the roller shutter shaft can be rotated very quickly without translation, since the manually operable drive element acts directly on the roller shutter shaft. Thus, a torque is transmitted from the manual actuatable drive element to the roller shutter shaft, wherein in the case of a designed as a geared motor electric drive, the transmission is bridged. Furthermore, a compact design of the drive device is achieved via the inner part, which fulfills several functions, since additional components, such as an additional bearing, are dispensed with. Thus, potential assembly errors are avoided and allow easier maintenance of the drive device. In addition to a new production of a roller shutter with the drive device according to the invention, the simple retrofitting of an existing roller shutter with the drive device according to the invention is possible. As a manually operable drive element is a drive element to understand that an operator must constantly exert a force to rotate the shutter shaft over any angle or to pull up the blind. Thus, a storage element, can be driven by the stored energy of a roller shutter shaft, excluded as a manually operable drive element in the invention. Furthermore, the direct arrangement of the manually operable drive element on the inner part means that no further component or no further component except for a fastening element (if present) is provided between the manually operable drive element and the inner part. In the second case, the fastening element, which may be formed, for example, as a screw, adhesive, etc., used for securing the manually operable drive element on the inner part.

The dependent claims show preferred developments of the invention.

Preferably, at least one first housing bearing shell is formed in / on the housing. Furthermore, at least one first inner part storage shell is preferably formed in / on the inner part. In the first housing bearing shell and in the first Innenteilillagerschale common rolling elements are arranged, whereby the inner part is rotatably mounted on the housing part.

The phrase "in / on the housing" means that the first housing bearing shell is integrally molded in the housing. Accordingly, by the phrase "in / on the inner part" it is meant that the first inner part storage shell is integrally formed in the inner part. Advantageously, the first housing-bearing shell and the first inner-part bearing shell are formed by material removal from the housing and inner part.

Particularly preferably, the housing is formed in two parts. Thus, the housing has a first housing part and a second housing part. Furthermore, the housing is provided with a second housing bearing shell. In this case, the first housing bearing shell in / on the first housing part and the second housing bearing shell in / on the second housing part are formed. In the inner part, a second Innenteilillagerschale is also provided. In the second Innenteilillagerschale and in the second housing bearing shell common rolling elements are arranged. This allows an even better storage of the inner part of the housing. By the words "in / on the first housing part", "in / on the second housing part" or "in / on the inner part" is meant that the bearing shells are each part of the corresponding component in which they are formed. Thus, no additional bearings are required for the storage of the inner part of the housing.

According to a particular embodiment of the invention, the first and / or the second housing bearing shell, and / or the first and / or the second Innenteilillagerschale are each formed as an annular groove. Thus, a uniform support of the inner part is made possible on the housing, which is particularly advantageous in a complete rotation of the inner part.

Preferably, the locking device has a locking element and a magnet, wherein the magnet is arranged on the inner part. The magnet is further arranged to hold the locking element in Arretierungszustand. In this state, the locking element connects the inner part with the housing, whereby a rotational movement of the inner part is prevented with respect to the housing. By providing a magnet, a very simple and fail-safe design solution for the locking device is achieved. In addition, a destructive multiple blocking or release of the inner part can take place. The magnet is advantageously designed as a permanent magnet (also called permanent magnet).

Alternatively or additionally, the locking can also take place in mechanical form. Accordingly, the locking element may preferably be formed as a splint or comprise a split pin which passes through two eyelets, wherein one eyelet on the housing and the other eyelet on the inner part are arranged. The eyelets are part of the locking device. Thus, a rotational movement of the inner part relative to the housing can be prevented when the locking device is in the locked state, that is, when the splint connects the housing with the inner part via the eyelets. Other locking devices, which achieve a locking of the inner part with respect to the housing by mechanical means, are also conceivable.

According to a particularly preferred embodiment, the locking element of the locking device may be formed as a splint, which is engageable in detents of a locking disk. The locking disc is part of the locking device. The split pin is advantageously arranged on the housing, wherein the locking disk is secured against rotation on the inner part.

The first position corresponds to the Arretierungszustand the locking device, which engages in this position, the cotter pin or the nose of the cotter pin in the locking disk. The second position of the pin corresponds to the unlocked state of the locking device, in which the cotter pin or the nose of the pin is not in engagement with the locking disc.

The locking disk is preferably designed as a toothed rim.

Furthermore, the split pin can preferably be L-shaped or straight-shaped.

Furthermore, the split pin is advantageously arranged rotatably on the housing. Due to its rotatability, the split pin can be brought into the first position and the second position in a simple manner. Alternatively, the split pin may be slidably disposed in the housing to effect the locking or unlocking of the locking device.

Between the housing and the split pin, a first lever is preferably arranged, with which the split pin is connected. The first lever is preferably rotatably arranged on the housing. This allows the cotter pin to turn with the first lever.

The intervention is carried out in an advantageous manner toothed areas of the first lever and the second lever. The toothed areas are preferably designed such that a rotational movement of the first lever and the second lever is synchronized with a rotational movement of the locking disk.

Upon release of the locking device, that is, when the manually operable drive element is pulled, the first lever and / or the second lever are driven out, whereby the cotter pin is taken.

In each case a first and / or a second through-hole may be provided in the first lever and / or the second lever. Through each first through hole, which is preferably in relation to a center of the drive device compared to the second through hole outside, passes a first bolt, by means of which the first lever and / or the second lever are arranged on the housing. The first bolt through the first lever also passes through a first hole of the cotter pin.

Through the second through hole in the first and / or second lever, a second pin is preferably set in each case. The second bolt on the first lever preferably connects the first lever to the split pin by inserting the second bolt into a second hole of the split pin.

The second bolts on the first and / or second lever serve as guide elements for the first and / or the second lever and the cotter pin. For a guide channel for the second pin is preferably formed in the housing. In particular, the guide channels are designed such that the first and / or the second lever can be pulled out to the extent that the split pin is no longer engaged in the locking disk. Preferably, the first lever and / or the second lever are spring-loaded, so that the cotter pin repeatedly recoils as soon as the manually operable drive element is not pulled.

The first and / or second lever are preferably arranged in the fourth recess of the housing.

In a further preferred embodiment of the locking device, the first lever is designed such that the first lever is movable laterally or in the circumferential direction of the housing in the fourth recess of the housing.

In order to bring the split pin in a locked state or an unlocked state, a guide opening is provided in the first lever. In the guide opening, a bolt connected to the split pin can move.

In particular, the guide opening is V-shaped. In this case, the tip of the V-shaped guide opening preferably corresponds to a locking state of the locking device. That is, the locking device is locked when the split pin is in place of the tip of the guide hole. Accordingly, the locking device is unlocked when the split pin is located at one end of one of the legs of the V-shaped guide opening.

Preferably, the manually operable drive element with the locking element and / or another component of the locking device is connected and / or cooperable such that upon actuation of the drive element, the locking device is brought into the unlocked state. Thus, the operations of releasing rotational movement of the inner part and actually rotating the inner part or the roller shutter shaft can be started by a single operation step. Of course, this can also be done by pressing the locking element. That is, the actuatable drive element is operated when the locking element and / or another component of the locking device is actuated or pulled.

The receiving area for receiving the non-movable part of the electric drive is preferably designed as a separate component which is detachably and non-rotatably connected to the inner part. In this way, for example, in the event of a call the component can be quickly removed and replaced with a new component. In addition, thus, the drive device can be combined with different electric drives, which increases the flexibility and retrofitting of the drive device.

In this case, the contact element is set up to be electrically connected to the electric drive. Furthermore, the electrical conductor track is set up to be connected to a power supply. By making the sliding contact a twisting of the cable on the side of the power supply is avoided. On the side of the electric drive, this is preferably avoided by arranging the cable of the electric drive at its non-moving part. Upon rotation of the inner part and thus the roller shutter shaft in the unlocked state of the locking device, the non-movable part of the electric drive rotates with the inner part. In particular, the contact element is designed as a circuit board. Preferably, there are four electrical interconnects provided, which can contact with four pins of the printed circuit board shaped contact element. The interconnects are preferably formed as copper interconnects.

The contact element and the electrical path are preferably prefabricated. Thus, a quick assembly of the arrangement of the contact element and the electrical path in the drive device can be made possible without these components having to be mounted individually.

In particular, the roller shutter shaft 51 is formed as a hollow shaft, wherein the electric drive 52 is arranged in the roller shutter shaft 51 and preferably designed as a tubular motor. Advantageously, the drive device 1 and the electric drive 52 are arranged on the same side of the roller shutter shaft 51.

Furthermore, the electric drive 52 has a movable part 53 and a non-movable part 54. The movable member 53 is rotatably connected to the shutter shaft 51 to transmit the torque generated by the electric drive 52 to the shutter shaft 51.

Advantageously, the non-movable part 54 comprises a stator of the electric drive 52 and / or a housing of the electric drive 52, which is rotatably connected to the stator.

Preferably, the movable part 53 of the electric drive 52 has a motor shaft 55 on which a coupling adapter 56 is arranged. About the coupling adapter 56, the motor shaft 55 is rotatably connected to the shutter shaft 51. On the shutter shaft 51 is via suspension spring (not shown), which are fixed in the roller shutter shaft 51 recesses 57 mounted (not shown) roller shutter. The roller shutter shaft 51 is preferably configured in the shape of an octagonal shaft.

The drive device 1 comprises a housing 2 and an inner part 3. Preferably, the housing 2 is formed in two parts, wherein a first housing part 20 and a second housing part 21, for example by means of screws, are interconnected.

The inner part 3 is rotatably mounted on the housing 2, and has a receiving area 30 for non-rotatable receiving the non-movable part 54 of the electric drive 52. The non-movable part 54 is formed as a motor head of the electric drive 52. Advantageously, the receiving area 30 is formed as a separate component 31 (drive receiving part), which is releasably connected to the inner part 3 and rotatably connected. Thus, the drive device 1 can be used with different electric drives.

Furthermore, the drive device 1 comprises a manually operable drive element 4, which is arranged on the inner part 3 and serves for manually driving the roller shutter shaft 51. In the drive device 1, a locking device 6 is further provided with a locking element 60. The locking element 60 is designed in particular as a split pin. The locking device 6 is configured to block a rotational movement of the inner part 3 in a locked state, the roller shutter shaft 51 being driven by the electric drive 52 in a first mode (operating mode). In the unlocked state of the drive device 6 after actuation of the drive device 6, a rotational movement of the inner part 3 is released, wherein the roller shutter shaft 51 can be manually driven in a second mode (operating mode). The manually operable drive element 4 is preferably connected directly to the inner part 3 and wound around the inner part 3. In particular, the manually operable drive element 4 is formed as a belt.

In order to facilitate the operation of the drive device 1, the manually operable drive element 4 and the locking element 60 are preferably attached to a common handle, which is referred to here as an emergency release 9. The emergency release 9 is optional. This means that an operator can directly grasp the manually operable drive element 4 and / or the arresting element 60 or can directly pull on the manually operable drive element 4 and / or the arresting element 60. The locking element 60 and / or the manually operable drive element 4 play the role of the emergency release.

Out Fig. 2 it can be seen that the inner part 3 is provided with a first recess 33, which in the assembled state of the drive device 1 with a cover 32 (FIG. Fig. 1 ) is covered. The cover 32 is in Fig. 2 away. The first recess 33 serves to receive a contact element 34 and at least part of a cable 58 of the electric drive 52, wherein the cable 58 is connected to the contact element 34 for establishing an electrical connection between the inner part 3 and the electric drive 52. For this, the contact element 34 is preferably provided with a connection terminal, in particular a wago clamp. For the purpose of receiving at least part of the cable 58, the separate component 31, which serves as the receiving region 30, preferably has a second recess 35. The second recess 35 is formed in particular as a groove.

The Fig. 3 shows a perspective view of the first housing part 20 from the right. The direction "from the right" corresponds to a direction from the drive device 1 to the electric drive 52 in the mounted state of the drive device 1. Thus, in FIG Fig. 3 an inside of the first housing member 20 is shown, which is not visible in the assembled state of the drive device 1.

The first housing part 20 is preferably formed as a circular plate. For receiving at least a part of the inner part 3, the first housing part 20 has a first through opening 23. In the assembled state of the drive device 1 advantageously the first housing part 20 and the inner part 3 are flush with each other. Thus, the structure of the drive device 1 is compact.

Furthermore, a second through opening 24 is formed in the first housing part 20, which connects an interior of the drive device 1 with an outside space, and through which the manually operable drive element 4 can pass. Furthermore, a third through opening 25 is formed on the first housing part 20, through which the locking element 60 can pass in the locked state of the locking device 6.

Preferably, the second through opening 24 and the third through opening 25 are formed perpendicular to a circumference of the first housing part 20, in particular in the radial direction. The second through opening 24 and a fourth through opening 28 of the second housing part 21 (FIG. Fig. 8 ) are designed such that they also serve as a guide or guide channels of the manually operable drive element 4.

On the first housing part 20, a first housing bearing shell 22 is further formed.

The Fig. 4 shows a perspective view of the drive device 1, from which the first housing part 20 is removed. So are in Fig. 4 basically the inner part 3 and the second housing part 21 shown. From the inner part 3, the cover 32 is further removed.

To the inner part 3, the manually operable drive element 4 is wound. For fixing the manually operable drive element 4 on the inner part 3, a screw 36 is provided. The inner part 3 also has a first inner bearing shell 37, are arranged in the rolling elements 82. It should be noted that the rolling elements 82 are partially arranged in the mounted state of the drive device 1 in the first housing bearing shell 22, so that the inner part 3 can rotate with respect to the first housing part 20.

The locking device 6 comprises, in addition to the locking element 60, a magnet 61 which is positioned in the inner part 3 under the cover 32. In Arretierungszustand the locking device 6, the locking element 60 is pulled by the magnet 61. The Fig. 4 shows the locking device 6 in the unlocked state.

The locking element 60 is preferably formed as a pin having ferromagnetic properties.

Alternatively or additionally, the locking can be accomplished by mechanical means. In this case, for example, the inner part 3, a first eyelet and the housing 2 have a second eyelet. The locking element 60, in particular in the form of a pin, pin or bolt, can engage in the locking of the locking device 6 in the eyelets, whereby a relative movement of the inner part 3 is locked to the housing 2. To release this movement, the locking element 60 must be pulled in this case, so that the locking element 60 is no longer in engagement with the eyelets.

The FIGS. 5 and 6 show perspective views of the inner part 3 from the left and right. It should be recalled that the direction "from the left" corresponds to the direction from the electric drive 52 to the drive device 1 in the mounted state of the drive device 1. So is in Fig. 5 a first side of the inner part 3 is shown, which faces the inside of the first housing part 20 in the mounted state. Accordingly, the shows Fig. 6 a second side of the inner part 3, which faces away from the inside of the first housing part 20 and faces an inner side of the second housing part 21.

From the FIGS. 5 and 6 It can be seen that the inner part 3 has a fifth through-opening 38 into which the locking element 60 is inserted in order to be connected to the magnet 6 in the locked state of the locking device 6. The opening 38 is coaxial with the third through opening 25 of the first housing part 20 (FIG. Fig. 3 ) educated. In this case, these openings are formed such that they serve as a guide for the locking element 60. For rotatably receiving the separate component 31, which serves as the receiving area 30, a sixth through opening 39 is formed in the inner part 3. The sixth through hole 39 and the member 31 are designed such that on the one hand, the rotationally fixed attachment between the component 31 and the sixth through hole 39 is effected, and on the other alignment error in the assembly of the component 31 can be avoided. For this purpose, preferably projections 80 (ear) are formed on the component 31 ( Fig. 4 ).

The FIGS. 6 and 7 show different views of the inner part 3 from the right.

For better storage of the inner part 3 on the housing 2, the inner part 3 with a second Innenteilillagerschale 85 and the second housing part 21 with a second housing bearing shell 27 (FIGS. Fig. 8 ) Mistake. In the second Innenteilillagerschale 85 and in the second housing bearing shell 27 common rolling elements 83 are arranged ( Fig. 8 ).

Preferably, all housing bearing shells and inner bearing shells are designed as annular grooves. This allows a uniform loading of the inner part 3 and the housing parts 20, 21, in particular in the case of several complete rotations of the inner part 3.

Like from the FIGS. 6 and 7 it can be seen, the inner part 3 on a seventh through opening 86, which is in particular formed of a plurality of slot-shaped partial openings. Thus, pins 81 of the contact element 34 with electrical interconnects 26 (FIG. Fig. 8 ), which are arranged on the second housing part 21, electrically contact.

The contact element 34 and the interconnects 26 thus form a sliding contact or a sliding contact. For connecting the electrical interconnects 26 to a power supply 87 (FIG. FIGS. 1 and 10 ) a third recess 29 is further formed on the second housing part 21 ( Fig. 9 ). The third recess 29 is covered in the assembled state of the drive device 1 with a cover 88 ( Fig. 10 ). The electrical contacting of the power supply 87 with the interconnects 26 is in the enlarged range of Fig. 10 better to see.

The assembly of the drive device 1 and the position of these components relative to each other is in Figures 11 and 12 illustrated more clearly. In particular, the shows Fig. 11 an exploded view of the drive device 1 from the left, that is, as already mentioned, in the direction of the electric drive 52 to the drive device 1 in the mounted state of the drive device 1. Die Fig. 12 shows an exploded view of the drive device 1 from the right, that is, in the direction of the drive device 1 to the electric drive 52 in the mounted state of the drive device. 1

The manually operable drive element 4 is shown in both figures in the unfolded state. The length of the manually operable drive element 4 is for example four to five meters.

In the drive device 1 may preferably be provided for the manually operable drive element 4, a guide member 89. The guide member 89 is preferably adapted to be attached to a roller shutter box. Furthermore, a magnet 90 is preferably arranged on the emergency release 9, in particular in a recess of the emergency release 9. Furthermore, a magnet 91 is arranged on the guide element 89, in particular in a recess of the guide element 89. The magnets 90, 91 are arranged to be connected to each other in a locking state of the locking device 6. Thus, the emergency release 9 is held on the guide member 89. The magnets 90, 91 are in particular adapted to equalize or overcome the weight of the emergency release 9. Particularly preferably, the magnets 90, 91 are each formed in two parts.

At the emergency release 9 can optionally be attached a chain or a similar device, so that the emergency release 9 is suitable for the disabled or can be operated by old people or children. If no emergency release is present, this can be achieved in that the chain or similar component is attached directly to the manually operable drive element 4 and / or the manually operable drive element 4 has a sufficient length, so that disabled people or children, the drive element can press.

The following is with reference to the Fig. 11 and 12 the operation of the roller shutter 50 in the first and in the second mode explained.

In Fig. 11 the roller shutter 50 is shown in the first mode, in which the roller shutter shaft 51 can be operated via the movable part 53 of the electric drive 52. The first mode corresponds to a normal operation of the roller shutter 50. "Normal operation" means that the roller shutter mounted on the roller shutter shaft 51 can be powered up by the electric drive 52 (arrow P1) and shut down (arrow P2). In this case, the roller shutter shaft 51 rotates with respect to the drive device 1, wherein the non-movable part 54 of the electric drive 52 does not move.

In order to use the roller shutter 50 in an emergency (e.g., a fire), power failure or failure of the electric drive 52, the drive device 1 is used. In this case, the roller shutter shaft 51 is manually driven in the second mode.

To do this, the operator must pull the emergency release 9 (arrow P4 in Fig. 14 ), which is connected to the locking element 60. Thus, by pulling the emergency release 9, the force with which the magnet 61 holds the locking element 60 is overcome, and the locking element 60 is thus released. As a result, a rotational movement of the inner part 3 is made possible in the unlocked state of the locking device 6 (arrow P3).

Since the electric drive 52 is clamped on the non-movable part 54 on the inner part 3, and the electric drive 52 is not powered, the roller shutter shaft 51 can rotate with the inner part 3 (arrow P3). The non-movable part 54 of the electric drive 52 also rotates.

For this purpose, the operator of the drive device 1 must pull the manually operable drive element 4. Since the manually operable driving member 4 and the locking member 60 are advantageously connected to each other via the emergency trigger 9, the operator of the roller shutter 50 has to pull only once to unlock the inner member 3, and thus to rotate the shutter shaft 51. Suppose that the roller shutter in Fig. 12 has already shut down, the roller shutter can be raised by the drive device 1.

In Fig. 15 an area of a roller shutter box is shown, in which the roller shutter 50 is arranged with the drive device 1. From the Fig. 15 it can be seen that only the emergency release 9 can be seen from the outside. The roller shutter 50 and the drive device 1 are hidden in the shutter box.

The drive device 1 according to the invention offers the advantage of easy handling, wherein the roller shutter can be opened very quickly. This is particularly advantageous when the roller shutter is used in escape routes or emergency exits. Furthermore, a compact design is achieved, whereby a retrofitting of existing shutters without great effort is possible.

The following is with reference to the FIGS. 16 to 21 a drive device 1 according to a second embodiment of the present invention described in detail.

The difference between this drive device and the drive device 1 according to the first embodiment is basically the design of the locking device 6.

In this case, the locking element 60 of the locking device 6 is preferably formed as a splint. In particular, the sapwood is L-shaped and has a nose. The locking device 6 further comprises a locking disc 62 with detents 63, in which the locking element 60 and the nose of the split is engageable.

The locking element 60 is advantageously arranged on the housing 2, wherein the locking disc 62 is rotatably mounted on the inner part 3. In particular, the locking element 60 is positioned in a fourth recess 100 of the housing 2. The fourth recess 20 is preferably defined by respective recesses in the first housing part 20 and in the second housing part 21.

Particularly preferably, the locking element 60 is sprung, so that the locking element 60 from a second position ( Figures 19 and 20 ) into a first position ( Figures 17 and 18 ) can be returned quickly. The first position corresponds to the locking state of the locking device 6, wherein in this position the locking element 60 engages in the locking disk 62. The second position of the locking element 60 corresponds to the unlocked state of the locking device 6, in which the locking element 60 is not in engagement with the locking disc 62.

The locking disk 62 is preferably designed as a toothed rim.

Furthermore, the locking element 60 is rotatably arranged on the housing 2 in an advantageous manner. Thus, the locking member 60 can be brought to the first position and the second position in a simple manner. The locking element 60 is preferably rotatably arranged in a plane parallel to the plane of the housing 2 level of the housing, resulting in a more compact construction of the drive device 1.

Between the housing 2 and the locking element 60, a first lever 64 is preferably arranged, with which the locking element 60 is rotatably connected. The first lever 64 is preferably rotatably arranged on the housing 2. Thus, the locking element 60 can rotate with the first lever 64.

Furthermore, a second lever 65 is preferably provided, which is rotatably mounted on the housing 2 and is in engagement with the first lever 64. The engagement takes place in an advantageous manner by toothed regions 66 of the first lever 64 and the second lever 65. The toothed regions 66 are preferably designed such that a rotational movement of the first lever 64 and the second lever 65 is synchronized with a rotational movement of the detent disk 62.

A first through-hole 67 and / or a second through-hole 68 are preferably provided on the first lever 64 and the second lever 65, respectively. A first bolt 101 extends through each first through-hole 67, which is preferably outside with respect to a center of the housing 2 in comparison to the second through-hole 68. By means of the bolts 101, the first lever 64 and the second lever 62 are arranged on the housing 2 , The first bolt 101 of the first lever 64 also passes through a first hole 102 of the locking element 60.

By the second through holes 68, a second pin 103 is preferably set in each case. The second pin 103 on the side of the first lever 68 preferably connects the first one Lever 68 with the first lever 68 by the second pin 103 is inserted into a second hole 104 of the locking member 60.

The second bolts 103 serve as guide elements for the first lever 64, the second lever 65 and the locking element 60. For this purpose, preferably guide channels 105 in the housing 2, preferably in the second housing part 21, formed in which the second pin 103 can move.

In particular, the guide channels 105 are formed such that the levers 64, 65 can be pulled out to the extent that the locking element 60 is no longer engaged in the locking disc 62. Preferably, the first lever 64 and the second lever 65 are sprung, whereby the suspension of the locking element 60 is made possible. Thus, the locking element 60 can always snap back as soon as the manually operable drive element 4 is not pulled. For this purpose, preferably spring elements 109 are provided for the first lever 64 and the second lever 65, which are each formed as a leg spring.

The levers 64, 65 are preferably arranged completely in the locked state in the fourth recess 100 of the housing 2. This leads to an even smaller size of the drive device. 1

Upon release of the locking device 6, that is, when the manually operable drive member 4 is pulled, the first lever 64 and the second lever 65 are driven out, whereby the locking member 60 is taken along because of its connection with the first lever 64.

Thus, the locking device is unlocked and a rotational movement of the inner part is released. The rest of the operation of the roller shutter comprising a drive device 1 according to the second embodiment is the same as the roller shutter according to the first embodiment.

The following is with reference to the FIGS. 22 to 25 a drive device 1 according to a third embodiment of the present invention described in detail.

Here, the first lever 64 is formed such that the first lever 64 can move laterally in the circumferential direction of the housing 2 in the fourth recess 100 of the housing 2. It should be noted that in this drive device 1, only the first lever 64 (and not the second lever of the previous embodiment) is present.

In order to bring the locking element 60 in a locked state or an unlocked state, a guide opening 106 is provided in the first lever 64. In the Guide opening 106 may move a bolt 107 connected to the locking member 60. Alternatively, the locking element 60 may comprise the bolt 107 or be integrally formed with the bolt 107. The locking element 60 is preferably formed as a straight-shaped or flat-shaped sapwood.

In particular, the guide opening 106 is V-shaped. In this case, the tip 106a of the V-shaped guide opening 106 preferably corresponds to a locking state of the locking device 6. That is to say that the locking device 6 is locked when the locking element 60 is located at the point of the tip 106a of the guide opening 106 ( Fig. 23 ). Accordingly, the locking device 6 is unlocked when the locking element 60 is located at one end 106b, c of one of the legs of the V-shaped guide opening 106 ( Figures 24 and 25 ).

The locking element 60 is preferably arranged displaceably in the housing 2 in order to effect the locking or the unlocking of the locking device 6. For this purpose, a recess 108 is preferably provided in the fourth recess 100 of the housing 2, in which the locking element 60 can be moved. In order to enable better guidance of the locking element 60, the recess 108 is provided with a guide channel 105 into which the bolt 107 is inserted.

For suspension of the locking element 60 spring elements 109 are preferably provided. The spring elements 109 are preferably arranged in the fourth recess 100 and act on the first lever 64.

The triggering of the locking device 6 takes place by pulling the manually operable drive element. 4

Due to the configuration of the locking device 6 according to this embodiment, a movement of the first lever 64 in the circumferential direction of the housing 2 is converted into a radial movement of the locking element 60.

To facilitate the operation of the drive device 1 or the operation of the manually operable drive element 4 by children or disabled people, a receiving device 110 for receiving the manually operable drive element 4 may preferably be provided.

This is in the Figures 26 and 27 shown. In particular shows Fig. 26 the receiving device 110 in an assembled state, wherein the receiving device 110 is attached to a masonry 200 (in the shell state). In Fig. 27 is a view of a portion of the receiving device 110 of Fig. 26 shown from behind, from which the masonry 200 facing the back of the receiving device 110 can be seen.

The receiving device 110 is preferably designed as a flush-mounted system. Thus, the receiving device 110 is covered in the finished state of construction of the masonry 200, whereby increased safety for the operator is ensured and an aesthetic appearance of the drive device 1 is achieved.

The receiving device 110 preferably comprises two profiles 111, preferably metal profiles, particularly preferably aluminum profiles, which can telescope into one another. Thus, the length of the receiver 110 can be set between a minimum value and a maximum value.

The profiles 111 are preferably designed to be the same length. Particularly preferably, each profile 111 has a length of 80 cm. Thus, the profiles 111 can be extended from 80 cm to about 160 cm.

Alternatively, the receptacle 110 may comprise a single profile. In this case, the profile has a length which is suitable for the specific application in which the drive device 1 is used.

The profiles 111 are preferably screwed onto the masonry 200 with tabs or straps 112. Other methods of securing the profiles 111 are also possible.

The brackets 112 and the profiles 111 are formed and arranged with respect to each other such that the arrangement of the brackets 112 and the profiles 111 at the thickest point is preferably 10 mm thick. This makes it easy to apply gypsum plaster or lime cement plaster with a thickness of 12 mm to 13 mm (finished brickwork condition). It should be noted that 13 mm is a regular plaster thickness.

Further preferably, the profiles 111 are each formed as a tube, in particular as a square tube, with a profile passage opening 113. Furthermore, each profile 111 comprises at least one profile opening 114. The profile opening 114 is shaped, in particular, in a surface area of the profile 111 which, in the mounted state of the receiving device 110, runs essentially parallel to the masonry 200. Particularly preferably, the profile openings 114 are rectangular.

The one profile opening 114, which faces the roller shutter box (upper profile opening), preferably serves as an inlet for the manually operable drive element 4, the other profile opening 114, which faces away from the roller shutter box (lower profile opening), as an outlet for the manually operable drive element 4 serves. Thus, the manually operable drive element 4 is preferably on the upper profile opening in the profile through holes 113 and the lower profile opening out again.

The profiles 111 are arranged in the assembled state with respect to each other such that the one profile opening 114 facing the masonry 200 (rear profile opening) and the other profile opening 114 facing away from the masonry 200 (front profile opening). This allows a better handling of the manually operable drive element 4, since a lateral movement and / or a rotation of the manually operable drive element 4 is reduced or eliminated due to the described arrangement of the profile openings 114. Particularly preferred is the masonry 200 facing profile opening 114, the upper profile opening, and facing away from the masonry 200 profile opening 114, the lower profile opening.

Furthermore, the profiles 111 are positioned in one another in the mounted state such that both profile openings 114 are free, that is to say that the profile opening 114 of one profile 111 is not covered by the other profile 111.

First, the profiles 111 are mounted to the brickwork 200 (in the raw state). Subsequently, the manually operable drive element 4 is inserted through the rear upper profile opening, so that the manually operable drive element 4 can be led out on the other side through the front lower profile opening.

On the lower side can preferably still be mounted in front of the outlet for the manually operable drive element 4. Adjacent to this panel, the emergency release 9, which is connected to the manually operable drive element 4, be arranged.

By providing the described receiving device 110, it is possible to set the height at which the manually operable drive element 4 must be actuated by the operator of the drive device 1 as needed. Thus, it is possible, for example, to raise the manually actuable drive element 4 at waist height and not at the level of the underbody of the roller shutter box, which is typically 220 cm.

As in the case of the drive device 1 of the first exemplary embodiment, a chain or the like may also preferably be provided on the emergency release 9 or on the manually operable drive element 4.

Although the receiving device 110 has been described in the context of the second embodiment, the receiving device 110 can also be used in the drive device 1 of the first embodiment. In this case, the locking element 60 is preferably formed so long that the locking element 60 of the one Profile opening 114 extends through the profile passage openings 113 of the profiles 111 to the other profile opening 114.

In addition to the above written description of the invention is to the additional disclosure hereby explicitly to the drawings of the invention in the Fig. 1 to 27 Referenced.
