Description

The invention relates to a door assembly, in particular house or balcony door assembly, comprising a relatively movable to a frame door, with a locking device which locks by at least one locking element in a locked state, the door leaf on the frame and the door in an unlocked state relative to the frame releases, wherein for selection of the state of the locking device is provided by an operator mechanically operable actuator, and wherein the locking means for transmitting a movement of the actuating element on the at least one locking element has a displaceably arranged on the door pull or drive rod, wherein a motor drive unit is provided for driving the pull or drive rod, wherein a sensor device is provided for particular non-contact detection of movement of the pull or drive rod and wherein the motor drive unit in response to a detected by means of the sensor device movement of the pull or drive rod is activated, wherein a first part of the sensor device is formed by a portion of the pull or drive rod and a second part of the sensor device is arranged door leaf fixed.

A door assembly has become known under the name "GU-SECURY Automatic with A-opener" by the Applicant Gretsch-Unitas GmbH Baubeschläge, Johann-Maus-Straße 3, 71254 Ditzingen. The previously known door arrangement has the advantage that the motor drive unit provides an additional drive possibility for driving the pull or drive rod, so that a locking state of the locking device is independent of an operating state of the actuating element (eg. A pusher or a lock cylinder) is variable. In this way, a remote control of the locking device can be realized, for example, to unlock the front door of a multi-family house by means of a drive unit provided on the housing side. Door arrangements with the features of the preamble of claim 1 are known from EP 0 564 441 A1 , of the EP 2 642 050 A2 , of the DE 10 2012 203 593 A1 and the DE 20 2012 007 916 U1 known.

The invention has for its object to provide a door assembly as simple as possible.

This object is achieved in a door assembly with the features of the preamble according to the invention by the characterizing features of Patent claim 1 solved.

It has been recognized that under unfavorable conditions it may happen that an operation of the actuating element independent of the motor drive unit is accompanied by increased operating forces. It has further been recognized that the pull or drive rod is moved upon actuation of the actuator and that this movement can be detected. The detection of the movement of the pull or drive rod is non-contact, so that the motion detection as such in turn does not contribute to increase the necessary for operation of the actuator operating forces. In addition, it was recognized that the operating forces for a displacement of the pull or drive rod in an initial movement of the pull or drive rod out of a rest position are still relatively small, at least as long as such a movement of the pull or drive rod is not yet for a change of Locking state of the at least one locking element is effective. Finally, it was recognized that a further, the initial movement downstream movement of the pull or drive rod can be done by the (for example, for the purpose of remote control) already existing drive device is activated and thus the downstream movement of the pull or drive rod, which for a Changing the locking state of the at least one locking element is effective, is effected by the motor drive means. This motor drive the pull or drive rod can in particular be independent of an operating state of the actuating element, so that a change in the locking state of the at least one locking element exclusively by the action of the motor drive means and without operating forces must be exerted on the control.

Overall, a very easy to use door assembly is created, which is particularly suitable for stiff locking devices.

According to the invention, it is provided that a first part of the sensor device is formed by a section of the pull or drive rod and a second part of the sensor device is arranged fixed door leaf. This has the advantage that a movement of the pull or drive rod can be detected directly without the traction or drive rod would have to be changed or rebuilt by means of an additional sensor part. This is particularly advantageous in view of the fact that the aforementioned known systems can be retrofitted in a simple manner.

In the section of the pulling or driving rod, which forms the first part of the sensor device, according to the invention is a Materialausnehmung or -aussparung the pull or drive rod, in particular in the form of a Langloch pocket or -durchbrechung. Such Materialausnehmungen or recesses are provided in prior art and conventional pull or drive rods to screw the lock in the door and to still allow free movement of the pull or drive rod between forearm and door. Advantageously, therefore Langloch pockets or openings can be used without a modification of the previously known pull or drive rods is required. This also creates a particularly simple retrofit option for the aforementioned known systems.

A particularly preferred embodiment of the invention provides that the second part of the sensor device is designed in the form of a coil for generating a variable depending on the position of the pull or drive rod magnetic field. Such a coil allows the use of an unmodified pull or drive rod described above. As a result, a non-contact sensor device can be provided which, moreover, is insusceptible to disturbances, for example due to dirt.

In addition or as an alternative to the use of a coil, the second part of the sensor device is designed in the form of an optical sensor.

Furthermore, it is advantageous if the second part of the sensor device and the motor drive device are arranged in a common housing.

This has the advantage that the motor drive device of a previously mentioned, previously known system can be exchanged in a simple manner, without having to provide additional space for the second part of the sensor device. This also makes a simple retrofitting possible.

The invention is particularly advantageous when the locking device comprises a plurality of locking elements, which cooperates with the pull or drive rod. Such locking devices create a higher burglary resistance, especially for exterior building doors; However, the use of a plurality of locking elements is accompanied by an increase in the total required for the actuation of the locking elements operating force. Therefore, it is particularly advantageous for a plurality of locking elements, when the motor drive unit after detecting an initial movement of the pull or drive rod causes the further, subsequent movement of the pull or drive rod and thus drives the locking elements independently operable by the operator actuator.

The activation of the motor drive unit as a function of detected by means of the sensor device movement of the pull or drive rod is preferably carried out for the purpose of transferring the locking device from the locked state to the unlocked state, especially exclusively for the purpose of transferring the locking device from the locked state in the unlocked Condition and not for the purpose of the transfer of the locking device from the unlocked state to the locked state. This has the advantage that a security reasons desired unlocking the locking device can be triggered by initially low operating forces on the actuator. This is especially true advantageous if the operator is a child or a frail person.

In the event that the motor drive unit does not serve to transfer the locking device from the unlocked state to the locked state, it is preferable for the motor drive unit to unlock the traction rod from the locked state to the unlocked position by means of a pressure force transmission unit in an opening direction Condition transferred and the motor drive unit is decoupled in a direction opposite to the opening direction closing direction of the pull or drive rod. In this way, it is possible that a release of the locking device by means of the motor drive unit, but that in a power failure and a failure of the motor drive unit, the pull or drive rod yet - when applying the necessary unlocking for operating forces, but not against a self-locking of motor drive unit - both in the opening direction for unlocking the locking device and in the closing direction for locking the locking device is actuated. The motor drive unit is then effective only in the opening direction and not coupled in the closing direction with the pull or drive rod.

When using a pressure force transmission unit mentioned above, it is particularly preferred that an initial movement of the pull or drive rod, which is caused by the actuating element, associated with a dead stroke of the pull or drive rod, with a subsequent to the idle stroke system of a force receiving surface Pull or drive rod ends at a power transmission surface of the motor drive unit. In this way it is ensured that an initial movement of the pull or drive rod is in any case unaffected by a self-locking of the motor drive unit.

In a further embodiment not belonging to the invention, it is provided that a first part of the sensor device is formed by an additional element motion-coupled with the pull or drive rod and that a second part Part of the sensor device is arranged door leaf fixed. The use of an additional element has the advantage that it can be optimized with regard to a particularly reliable and precise detection of a movement of the additional element. Advantageously, the additional element has only the aforementioned functions. This allows a simple retrofitting of an additional element of existing systems.

It is possible that the additional element and the pull or drive rod are fixedly and immovably connected to each other, for example by a positive and / or non-positive connection.

However, it is preferred if the additional element and the pull or drive rod are coupled together so that the pull or drive rod when moving in a first direction of movement drives the additional element and that the additional element upon movement of the pull or drive rod in one of the first Movement direction opposite second direction of movement is decoupled from the pull or drive rod. This can be achieved, for example, by virtue of the additional element having a driver section which cooperates with only one boundary of a material recess or recess formed in the pull or drive rod (in particular in the form of an elongated pocket or opening). Preferably, the first direction of movement corresponds to an unlocking of the locking device ("opening direction"), while the second direction of movement corresponds to a locking of the locking device ("closing direction").

In the event that the additional element is not coupled in both mutually opposite directions of movement of the pull or drive rod with this, it is advantageous to provide a restoring device which the additional element from a deflected position (in which the additional element by means of the pull or drive rod brought back) to a basic position. The restoring device may comprise, for example, a compression or tension spring.

Furthermore, it is preferred if the second part of the sensor device in the form of a coil or another suitably shaped electrical Ladder is designed to generate a changing depending on the position of the additional element electrical, magnetic or electromagnetic field. In particular, exactly one and only one coil or just one suitably shaped electrical conductor is provided. A coil or a suitably shaped electrical conductor allows the detection of a movement and / or the detection of a position of the additional element. As a result, a non-contact sensor device can be provided which, moreover, is insusceptible to disturbances, for example due to dirt.

The additional element is preferably at least partially, in particular made entirely of a ferromagnetic material, in particular of iron. Such a material influences a magnetic field whose properties vary from the viewpoint of the second part of the sensor device upon a displacement of the additional element, so that a movement of the additional element can be detected and / or a position of the additional element can be detected.

Regardless of the use of an additional element, in addition to or as an alternative to the use of a coil or another suitably shaped electrical conductor, other sensors may also be used as the second part of the sensor device, for example an optical sensor and / or a capacitive sensor that modifies an electric field detected.

Also, irrespective of the use of an additional element, it is also possible, unlike the feature "sensor device for non-contact detection of a movement ..." mentioned in patent claim 1, to use a sensor device which is not contactless. Examples of such non-contact sensor devices are mentioned below for an electrical sensor and for a mechanical sensor.

Likewise, as the second part of the sensor device, the use of an electrical sensor (eg a potentiometer), which detects the change of electrical parameters (eg, resistance, voltage, current, eddy currents), possible.

As a second part of the sensor device, a mechanical sensor can also be used, for example a microswitch.

Furthermore, it is advantageous if the second part of the sensor device and the motor drive device are arranged in a common housing. This has the advantage that the motor drive device of a previously mentioned, previously known system can be exchanged in a simple manner, without having to provide additional space for the second part of the sensor device. This also makes a simple retrofitting possible. In particular, it is preferable if a restoring device described above is arranged and / or mounted on or in the housing.

It is particularly preferred if the additional element has at least two material sections which are adjacent to one another viewed in the direction of movement of the additional element and which have different dimensions viewed transversely to the direction of movement of the additional element. In each case, more or less material is kept at the level of the mutually adjacent material sections, for example by varying the material thickness and / or height of the material sections. In the event that the material portions are made of an electrically and / or magnetically conductive material, the second part of the sensor device for a smaller material portion, a (n) other (s) electrical, magnetic or electromagnetic field strength or field profile in comparison to a field strength or capture a field history for a larger piece of material.

A not belonging to the invention embodiment provides that the additional element has at least one extending in the direction of movement of the additional element web, which has at least one stepped or inclined relative to the direction of movement boundary. The number of stages corresponding to different positions of the additional element can be detected; in the case of an inclined edge arranged even a resolution of the sensor device corresponding number of positions of the Additional element to be detected. In the simplest case, however, a movement of the additional element can be detected in any case.

Also conceivable is the detection of the movement and / or the position of the additional element by its partial arrangement within an electrical, magnetic or electromagnetic field, which is generated by a coil or by another suitably shaped electrical conductor.

An embodiment of a door arrangement is designated in the drawing as a whole by the reference numeral 10. The door assembly 10 includes a door panel 14 that is movable, such as pivotable, relative to a frame. For locking the door leaf 14 on the frame 12, a locking device 16 is provided, which in the illustrated embodiment comprises two locking elements 18, 20. An actuation of the locking device 16 can take place by means of an actuating element 22, for example in the form of a lock cylinder 24. It is also possible that a (not shown) door handle forms an actuating element 22 which cooperates with a pusher 26.

In the embodiment shown in the drawing, the actuating element 22 and / or the follower 26 is part of a Lock case 28. It is possible that the lock case 28 includes a latch 30 which is actuated directly by the actuating element 22, in particular in the form of the lock cylinder 24. The lock case 28 may additionally or alternatively to a latch 30 also include a latch 32, which is actuated directly by an actuator 22 in the form of a door handle and using the pusher 26.

For transmitting a movement of the actuating element 22 on the locking elements 18, 20, a pull or drive rod 34 is provided, which is covered in a mounted state on the door 14 by a forend 36. In particular, the pulling or driving rod 34 and the forend 36 extend along a vertically oriented, band-facing side of the door leaf 14.

The door assembly 10 further comprises a generally designated by the reference numeral 38 motor drive unit by means of which the pull or drive rod 34 is in particular directly driven, preferably exclusively in a in FIG. 3 indicated opening direction 40 of the pull or drive rod 34th

The motor drive unit 38 comprises a motor arranged within a housing 42, by means of which a drive element 44 in the opening direction 40 of the pull or drive rod 34 is movable and in this opposite direction. The drive element 44 has a force transmission surface 46, which is spaced in a locked state of the locking device 16 by a Leerhub 48 to a force receiving surface 50 of the traction or drive rod 34 positively and / or non-positively connected force receiving element 52.

The motor drive unit 38 can be fixedly connected to the forend 36 by means of screws 54. In this case, it is preferred that the motor drive unit 38 comprises projections 56, which in particular pass through material openings 58 of the pull or drive rod 34 formed as a slot opening. Here, one of the back of the forend 36 facing front of the projections 56 protrudes beyond a front side 60 of the pull or drive rod 34, so that the motor drive unit 38 on the one hand can be firmly connected to the forend 36 and on the other hand allows a free movement of the pull or drive rod 34 between the motor drive unit 38 and the forend 36.

The door arrangement 10 further comprises a sensor device 62 for contactless detection of a movement of the pull or drive rod 34. The sensor device 62 comprises a first sensor part 64, which is formed by a portion 66 of the pull or drive rod 34.

A second part 68 of the sensor device 62 is arranged fixed door leaf, so does not move together with the pull or drive rod 34. The second part 68 of the sensor device 62 is advantageously a coil 70, which by energizing a in FIG. 3 indicated magnetic field 72 generated. In the drawing, an embodiment with two coils 70 is shown; in another embodiment, only one coil 70 is provided.

The magnetic field 72 of one or the coil 70 is changed by a change in the position of the pull or drive rod 34, namely, that in the course of movement of the pull or drive rod 34, the degree of overlap of the slot-shaped material aperture 58 relative to the coil 70 changes , The change in the magnetic field 72 causes a change in a current flowing through the coil 70. This change is detected by a drive unit and used when exceeding a predefinable threshold value for activating the motor of the motor drive unit 38.

Starting from a closed state of the door leaf 14, in which the door leaf 14 rests against the frame 12 and starting from a locked state of the locking device 16 in which the locking elements 18 and 20 lock the door leaf 14 to the frame 12, causes an actuation of the actuating element 22 by an operator that the pull or drive rod 34, starting from the in FIG. 3 shown state is moved. Thanks to the idle stroke 48 while the pull or drive rod 34 against gravity (ie upwards) are moved; it is sufficient that the pull or drive rod 34 is moved starting from its rest position at all and get it the relative position of the material opening 58 of the pull or drive rod 34 relative to the coil 70 changes. The thereby detectable change in the magnetic field 72 is used by the drive unit of the motor drive unit 38 for activating the motor.

After overcoming the idle stroke 48 or a part of the idle stroke 48 and a subsequent installation of the force transmission surface 46 to the force receiving surface 50 causes a further drive of the drive member 44, a movement of the pull or drive rod 34 in the opening direction 40. In this way, the locking elements 16, 18 unlocked in a conventional manner; In this case, operating forces on the actuating element 22 can be entirely dispensed with.

After release of the locking device 16, the door 14 can be opened.

The locking elements 18, 20 are, for example, spring-actuated latch bolts. A transfer of the pull or drive rod 34 against the opening direction 40 can be done by the spring action and / or by the fact that the traction or drive rod 34 moves due to self-weight down.

The housing 42 is provided separately from the lock case 28. This simplifies the retrofitting of an existing system.

The magnetic field 72 is in particular an electromagnetic field.

In the FIG. 4 a not belonging to the invention assembly is shown, which instead of the in Fig. 2 shown components can be used. In Fig. 4 However, to improve clarity, the pull or drive rod 34 and the forend 36 are not shown. The functioning of the module according to Fig. 4 corresponds to the above with reference to the FIGS. 1 to 3 described operation; for identical or functionally identical components identical reference numerals are used. Also the assembly according to Fig. 4 includes a housing 42 and a motor drive 38. The drive 38 has a motor 74, which via an actuator 76 with a drive element 44 (see. Fig. 2 ) cooperates.

The module according to Fig. 4 comprises an additional element generally designated by the reference numeral 78 which slidably engages the housing 42 is mounted. The additional element 78 forms the first part 64 of the sensor device 62. The second part 68 of the sensor device 62 is formed by a single coil 70.

The additional element 78 is formed in particular in the form of a metal part, which is preferably produced by reshaping. The additional element 78 is in particular made of a magnetic material.

The additional element 78 has, for example, a material thickness 80 of approximately 0.5 mm to approximately 0.9 mm, in particular of approximately 0.7 mm (cf. FIGS. 5 and 6 ). The additional element 78 has a main plane 82 and an additional plane 84. The main plane 82 is disposed within the housing 42. The additional plane 84 extends parallel to the main plane 82 and offset in the direction of the forend 36.

The main plane 82 has a reference section 88 at a free end 86. This comprises two webs 90, which together define a gap 92. The webs have the intermediate space 92 facing boundaries 94. The edges 94 are oriented inclined to a main extension direction 96 of the additional element 78, for example at an angle of about 5 ° to about 30 °.

The main extension direction 96 of the additional element 78 corresponds to an axis along which the additional element 78 is movable relative to the housing 42. This axis runs parallel to a movement axis of the pull or drive rod 34. The movement axis 42 is defined by the opening direction 40 and a closing direction opposite thereto.

As a result of the inclined-oriented boundaries 94, the reference section 88 seen in the direction of movement of the additional element 78 adjacent to each other arranged smaller material portions 98 and larger material portions 100 on. These sections of material preferably merge into one another continuously.

The main portion 82 of the additional element 78 has at its end remote from the reference portion 88 an angled portion 102, which together with a fixed housing 104 (see FIG. Fig. 4 ) to Arrangement of a return device 106 in the form of a tension spring 108 is used.

The additional portion 84 has a driver portion 110 facing away from the housing 42, which has a (in the drawing lower) boundary 112 formed in the pull or drive rod 34 material recess or recess 58 in the form of an elongated pocket or opening ( see. Fig. 2 ) cooperates.

Upon movement of the pull or drive rod 34 in the opening direction 40, the boundary 112 of the material recess or recess 58 carries the additional element 78 in the identical direction so that the reference section 88 moves relative to the coil 70. This movement can be detected by means of the sensor device 62, in order subsequently to activate the motor drive unit 38, so that a further movement of the pull or drive rod 34 is assisted by a motor.

In the course of the displacement of the additional element 78, the restoring device 106 is tensioned. Now, if the pull or drive rod is moved in a direction opposite to the opening direction 40 closing direction, lifts the boundary 112 of the material recess or recess 58 of the cam portion 110 from. A return of the additional element back to the undeflected position is independent of the movement of the pull or drive rod 34 in that the stored energy in the restoring device 106 is released, in particular by the fact that the tension spring 108 contracts.

Incidentally, for example, with respect to the attachment of the housing 42 to the forend 36, is for in the FIGS. 4 to 6 illustrated embodiment to the description of the FIGS. 1 to 3 Referenced.
