Description

Device for pivoting rotatably mounted wing elements

The invention relates to a device for pivoting rotatably mounted wing elements, in particular rotatably mounted shutters, which are attached by means of bands to a solid component, such as a wall.

Rotatingly mounted wing elements, such as shutters, doors or gates, have long been known for closing wall openings or other passages of solid components. Their main tasks are u.a. It is to protect underlying equipment such as windows from the effects of the weather as well as from burglary. For opening and closing the wing elements, a number of mechanical devices are known.

The German Utility Model DE 93 19 914 Ul discloses a device for opening and closing a window or door leaf with a arranged in the direction of escape of a journal, umpolbaren electric motor and a safety slip clutch. The housing of the above the journal of a fitting arranged electric motor is supported against the wing member or against a wall, so that a torque for pivoting can be transmitted to the wing member. Since the motor is mounted axially between the wing element and the wall relative to the axis of rotation of the wing element, it is exposed to weather conditions and easily accessible to anyone, so that the proposed drive device does not provide effective anti-burglary protection. A similar electric drive device for a folding shutter or folding door arrangement is shown in WO 98/50661. Also in this drive device, the electric motor is arranged in extension of a journal. In order to keep the folding shutter or the flap door in a closed state when the drive device is de-energized, an additional locking mechanism is necessary. In the event of a break-in attempt, the drive s device for tampering is accessible. In order to further protect them from the weather, the electric motor must be encapsulated waterproof in its housing.

Object of the present invention is to provide a device for pivoting rotatably mounted wing elements, which is protected against manipulation attempts and weathering.

This object is achieved by a pivoting device according to the independent claim. The dependent claims relate to advantageous embodiments of the invention.

In a device according to the invention for pivoting rotatably mounted wing elements, which are attached by means of bands to a fixed component, a driving force or a torque for pivoting the wing member is transmitted to a pivot member. The pivot member causes a rotational movement of the wing member and can be rotatably connected to a belt.

As a wing element in the context of this application, all types of window, door or gate wings are to be understood, which can be pivoted about a horizontal or vertical axis of rotation. The wing members may be provided for closing a wall opening or passage, or for protecting behind-the-windows or doors be. In this case, one-winged or multi-winged (eg double-winged) designs can be used. A wing element is fastened with one or more bands, for example, to a wall or a post.

Preferably, a drive unit for generating the driving force for pivoting is arranged in the wing element. The drive input. unit can be located wholly or partially in the wing element. The arrangement of the drive unit in the wing element this is protected from the weather, such as rain, snow or intense sunlight, as well as manipulation attempts by unauthorized persons. In this way, an increased burglar resistance and less wear is achieved over the prior art.

Expediently, an axis of a rotating shaft of the drive unit, for example the rotor of an electric motor, is arranged in the interior of the wing element. The axis of the rotating shaft may be arranged parallel to a longitudinal axis or axis of rotation of the pivoting element. In this way, a favorable arrangement of the drive unit arises, wherein the axis of rotation of the drive unit is arranged parallel and / or offset in the radial direction to the axis of rotation of the wing member, wherein the drive unit may be provided protected by the wing member in its interior.

Preferably, the pivoting element is designed as a sleeve connected to the drive unit and a bearing pin provided on the belt. When sleeve and bearing pin are non-rotatably connected to each other and the sleeve is rotated by the drive unit with respect to the wing member in rotation, resulting in a torque which leads to a pivoting of the wing member. Of course you can the pivoting element may also be formed as a pin offset from the drive unit in rotation, which engages in a rotationally fixed manner in a sleeve attached to the belt.

For non-rotatable connection of pin and sleeve many positive designs are possible. It is particularly useful to make the inner shape of the sleeve and the outer shape of the pin polygonal.

The sleeve and. The pivot of the pivot member may also form a bearing element for the wing member, which allows pivoting of the wing member. By inserting the driven pin into a sleeve, a simple mounting of a pivotable about a vertical axis wing element is achieved. The sleeve also fulfills the function of a bearing element for the pivotable wing element by the weight of the wing member (or a part thereof) carries.

The pivoting device according to the invention can be realized in one or more of the bearing elements for a wing element. In principle, however, it is sufficient to replace a bearing element by a pivoting element according to the invention in order to pivot the wing element by means of the driving force. For larger doors or gates. However, it may be advantageous to design a plurality of bearing elements (hinges) as pivoting elements in order to distribute the necessary torque to a plurality of unit units, each associated with a pivoting element. This has the advantage that smaller drive units with lower power and size can be used, which can be accommodated more easily in the wing element. Conveniently, the longitudinal axis of the pivot member is arranged parallel to the center plane of the wing element (or their main directions) and offset with respect to this. This arrangement has the advantage that a fully open wing element can rest parallel to a projecting, with respect to the longitudinal axis of the pivoting member wall. The parallel displacement of the axis of the pivot member to a major axis of the median plane of the wing member, when opened, permits a parallel arrangement of the wing member and the exterior of the masonry and permits complete opening of the wing member.

It is particularly advantageous if the axis of rotation of the bearing element or the longitudinal axis of the pivoting element is arranged outside the space, which lies in extension of the wing element. In this case, the axis of rotation of the wing element is offset from this and allows complete opening, in which the pivoting device, for example. Positioned by 180 ° wing element positioned by a given offset to the longitudinal axis of the pivot member and so a complete opening of the wing element at a protruding wall opening allows. The position of the pivot axis relative to the intersection of the contact planes of the housing angle and shutter can be set so that in the closed state, the externally visible plane of the shutter is flush with the outside of the masonry. When open, both planes are parallel and aligned.

Preferably, the drive unit has an electric motor. This can be designed as a DC collector motor. However, other electric motors, such as alternating current or three-phase motors, can be used. Conveniently, the electric tromotor a rotation in both directions, so that opening and closing of the wing elements by reversing the direction of movement of the umpolbaren electric motor is achieved in a simple manner without a reverse gear is required.

The driving force can be transmitted via a gear unit from the motor to the pivot member and put this into rotation with respect to the wing member. By the gear unit, a reduction of the rotational speed of the drive unit and thus a larger torque or a smaller drive unit (lower power required, smaller dimensions) can be achieved. The reduction gear may be in the form of all known types of transmissions. Particularly advantageous is a planetary gear that has a small size. The reduction gear can also be designed as a structural unit with the motor (geared motor).

By a suitable design of the gear unit but also the offset between the longitudinal axis of the pivot member and the axis of the rotating shaft of the drive unit can be compensated. For this purpose, in particular a spur gear is expedient, which is driven by the drive unit and transmits two or more stages (gears) a driving force to the pivot member. The gear unit may also have a bevel gear, in which case the axis of the rotating shaft of the drive unit is not arranged parallel to the longitudinal axis of the pivot member. This allows, for example, a rectangular arrangement of the drive unit to the pivot axis, which may be advantageous to accommodate the drive unit in the wing element. The gear unit can also have a self-locking gear that allows a flow of force only from the drive unit to the pivoting element and not in the opposite direction of force. In this way, a self-locking or self-locking pivoting device can be realized in which the wing elements can not be moved by hand. This has the advantage of an increased burglary protection, since it is not possible for unauthorized persons to pivot and open a closed wing element when the drive unit is switched off. A self-locking gear requires no additional locking of the wing element. As a self-locking gear worm gear or circular thrust transmission can be provided.

According to a particularly advantageous embodiment of the invention, a circular slide transmission is provided. A circular thrust gear has a ring gear with an internal toothing and an eccentrically rotating spur gear with an external toothing, which runs in the ring gear. A circular thrust transmission in addition to its self-locking has the advantage that it allows a large translation in a small space.

For fixing the drive unit to the wing element, an angled retaining element can be provided. The angled retaining element, which carries the drive unit, can for this purpose be fastened to a recess of the wing element, so that the drive unit projects into the recess of the wing element and the angled retaining element covers the recess. Particularly useful are L-shaped or U-shaped holding elements. Depending on the nature of the wing element (eg material), an L-shaped or a U-shaped retaining element may be advantageous. U-shaped holding elements can in this case grip around the profile of the wing element and for increased Stability worry, especially. in wing members made of wood or similar material is appropriate. When designed as shutters wing elements, it proves to be advantageous if the drive unit is arranged in a recess (recess) of a frame of the shutter. The rest of the shutter can be a conventional one. Have structure. Such a design allows a subsequent installation of the drive unit in a shutter, with only one recess must be made in the frame to arrange the drive unit there. Since the recess is covered with the angled retaining element, the drive unit is not accessible after its installation from the outside and protected against the effects of weather.

In order to further increase the security against burglary, it is expedient to fasten the strip to the fixed component or the wall opening in such a way that it is not accessible from the outside when the wing element is closed. In this way prevents an unauthorized person solves the attachment of the tape from the solid component and so can open the wing element. Conveniently, the retaining element or the recess in the wing element is arranged so that it is not accessible from the outside when the wing element is closed.

A further improvement of the burglar resistance can be achieved by the band is fixed by means of a frame on the solid component. The frame is used for example in a window opening and prevents the tape can be separated by force of the wall opening. The frame is preferably an embodiment in solid material which is fastened in the wall opening by means of a number of fixed connections, eg screwed connections becomes. If a lesser degree of burglar resistance is sufficient, a profile frame can also be used. ^• .

The wing member may, for example, for closing a wall opening to be provided, it is advantageous if the strip and ^• the pivoting member are arranged such that the wing member does not protrude in the fully closed state via the wall opening. In this way it can be prevented that the wing element is broken out by the use of force, for example with a crowbar. If the wing element does not protrude beyond the wall opening, it forms less intervention options for the use of burglary tools.

The protection against unauthorized opening of the wing member can be further increased by an additional locking element, wherein the locking element prevents in the locked state, opening of the wing member by the locking member has a locking pin which in the locked state in a recess in another wing member or the fixed Component (for example, band or frame) protrudes.

Conveniently, the locking element has an actuating mechanism with which this is opened and closed. This can be done for example via an electromagnet and / or a spring element. The actuating mechanism may unlock the locking element (eg, by the solenoid) when the drive unit is actuated. For this purpose, it is only necessary that the actuating mechanism is connected to the power supply of the drive unit. If the drive unit and the actuating mechanism are de-energized, the spring element can, for example, Move the latch pin to the locked position or hold it there and prevent movement of the wing element. It should be noted that an effective locking of the wing element is achieved even by the provision of a self-locking gear. An additional locking element, however, can further increase the force a burglar has to apply to break the lock.

According to a preferred embodiment of the invention, a control unit for controlling the drive unit and / or the actuating mechanism for the locking element is provided. The control can be decentralized for individual wing elements or centrally for a plurality of wing elements, which are provided for example as doors or for the protection of windows of a building. Conveniently, this switch inside the building, a power supply and wiring are provided. The control lines for the drive unit may e.g. be provided by a wall penetration from the interior of the building to the disposed in the wing element drive unit. Of course, the cable bushing can also be done through the frame or the window frame.

According to a particularly preferred embodiment of the invention weather and / or weather sensors are provided, which are bound to the control unit and allow detection of weather and / or weather conditions. The control unit can be designed such that it controls the wing element automatically and this opens or closes in given weather and / or weather conditions, such as storm, rain, hail or the like. In this way, passages can be closed or windows and doors can be protected by closing the wing elements. the. This is especially beneficial in areas where frequent and possibly unexpectedly violent storms can occur:

The present invention provides a pivoting device for rotatably mounted wing elements, which, since the drive unit is arranged in the wing element, has a particularly high burglar resistance and weather resistance. The invention enables a motorized pivoting of the wing elements, which can be controlled by a user from a distance, for example from the inside of a building, or fully automatically. According to a preferred embodiment, the invention is provided with a self-locking gear that prevents inadvertent and / or unauthorized opening or closing of a wing element.

It can be seen that the upper band 2 'is designed as a conventional hinge for the window sash 1. On the lower band 2 is one of the drive unit 5. actuated pivoting element 4 is provided for pivoting the window sash 1. The upper band 2 'and the lower band 2 also act as bearing elements for the wing element 1 and define a vertical pivot or rotation axis for the wing element 1.

An enlarged detail of the area A in FIG. 2 is shown in FIG. 3. The angled retaining element 10, which is fastened to the frame 12 of the shutter 1, and the recess 11, in which the drive unit 5 is located, are discernible. The pivoting element 4 is rotatably connected to the band 2. The drive unit 5 generates a driving force which acts on the pivoting element 4 and pivots the window wing 1 via the reaction torque.

Fig. 4 shows a schematic section through a masonry 3 and a wing element 1, which is shown in the closed and opened state. The wing element 1, here a shutter, closes a window 30 in the closed state. Due to the offset of the drive shaft of the electric motor 20 and the rotational or longitudinal axis of the pivot element 4, the wing element 1 can be completely opened, being parallel to the outer wall in the opened state rests and in the closed state to the level of the outer wall side offset inwardly in the wall opening 14 is located.

Fig. 5 shows the drive unit 5 for generating the driving force. A DC collector motor 20 is fed via an electrical connection line, not shown, so that the rotor 16 is set in rotation. The control of the drive unit 5 takes place, for example from the inside of the building. For example, the control and power cables can be routed through the window frame. When the window sash is closed, the cable feed is located between shop 1 and window frame and is therefore protected against tampering attempts. When opened, it can be accessible and visible.

The gear unit 19 has a spur gear 8 with three gears for offsetting the axis 16 of the electric motor 20 from the longitudinal axis or axis of rotation of the pivoting element 4. A planetary gear for speed reduction is provided in unit with the motor 20. Next, a self-locking circular slide mechanism 9 is provided, which further reduces the speed and a. Torque on the pin 6 transmits. If this is set in rotation in relation to the drive unit 5 or the shutter 1, this leads to a pivoting movement of the shutter 1, since the pin 6 rotatably connected via a positive connection with the sleeve 7 with the band 2 and the fixed component 3 is.

The torque for pivoting the shutter 1 is generated by the geared motor 20 (DC motor with three-stage planetary gear unit for speed reduction). The support of the reaction torque of the geared motor 20 is effected by the gear plate 8a, on which the geared motor 20 is screwed. The spur gear 8, designed as a side gear with three gears, ensures the parallel displacement of the axis of the drive torque. The parallel shifted torque is introduced into an eccentric 21. The pivot bearings. the output shaft are located in the upper gear plate 8a. And the outer diameter of the conical part of the eccentric 21. This can be a static certainty guaranteed. ^"The Hohlradzentrierung 22 the bearing ring of the concentric part of which forms the eccentric 21st

The eccentric 21 drives the spur gear 24 of the circular thrust gear 9 to an eccentric movement, wherein the spur gear 24 outputs its torque directly to the pin 6 of the pivoting element 4. The external toothing of the spur gear 24 engages due to the eccentricity of the movement in the internal toothing of the larger ring gear 25 and rolls in this, wherein a torque in the ring gear 25 is formed. The ring gear 25, the ring gear plates 23 and 26 and the ring gear centering 22 are fixedly joined together (e.g., welded).

The Hohlradzentrierung 22 also causes the torque input of the circular thrust mechanism 9 in the holding element 10 via the gear plate 17 shown in Fig. 4. By using an external hexagonal profile in Hohlradzentrierung 22 can be dispensed with additional measure to absorb the torque. The torque is positively transmitted by means of the hexagon Hohlradzentrierung 22 in the transmission plate 17, the support member 10 and thus in the shutter 1.

The circular slide transmission 9 reaches a high reduction on a very small space. This allows those in front in the power train Components are designed to be small and space-saving. This makes it easier to accommodate the drive unit 5 in the wing element 1. ^•
