Description

The invention relates to a lock for along a travel movable or pivotable wings such as sliding sash or rotary wing and wing systems equipped with it, for example in the form of a sliding or revolving door system.

Latches for such systems per se are known.

The DE 20 2009 016 829 U1 discloses a sliding door with an additional carriage, which can be found, so that the relevant sliding door is prevented from moving, that is locked. This arrangement has the disadvantage that the locking device can be unlocked manually or hardly at great expense. In addition, it is only suitable for sliding sash systems.

The DE 20 2008 008 870 U1 describes a toilet room with a door that can be locked by means of a magnet. The unlocking can for example be done without contact using a footswitch. This has additional cabling. In particular, the floor and / or a wall in the toilet cell, for example, must be torn open in order to lay the cables as tamper-proof as possible. Another disadvantage is that such a door can not be locked if the power should fail. In addition, this lock is not very tamper-proof.

The object of the invention is to provide a universally applicable and easy-to-handle locking, in which in particular the aforementioned disadvantages are at least reduced.

This object is solved by the subject matter of claims 1 and 18. Advantageous developments of the invention are specified in the subclaims.

According to the invention, a lock is provided for a movable along a travel or pivotable wing, which has a locking device and an engagement recess. The engagement recess is at a stationary portion, i. H. a stationary with respect to the wing portion such as a floor or a ceiling of a room in which the at least one wing is arranged, or on one of the locking device facing, to the travel substantially parallel side of the wing or at one of the pivotal mounting of the Pivoting vane facing away from the end face of the pivoting vane in each case in the direction of locking device formed or arranged pointing. The locking device has an electromechanical drive mechanism which is set up, depending on the electrical control, to move a latch of the locking device out of a housing of the locking device into a locking position or to move it into the housing into an unlocking position. This has the advantage of a secure and thus little or no manipulation lock. The locking device is arranged such that the latch is in the locking position with the engagement recess in engagement, that the wing is locked to a movement in at least one direction. In unlocking position, however, the latch is out of engagement with the engagement recess, so that the movement of the wing is released. This solution has the advantage that the lock can be maintained even in case of power failure. In addition, the electromechanical drive mechanism allows a defined method of the bolt. The method of the bolt, so its translational movement, allows the arrangement of the engagement recess in many possible places. Advantageously, the engagement recess is part of a recessed grip, which can allow a manual movement of the wing, especially in sliding panels.

Preferably, the bolt performs a translational movement.

Preferably, the lock has a drive circuit coupled to the drive mechanism and a sensor system coupled to the drive circuit with at least one sensor. This at least one sensor monitors a respectively associated area in front of the locking device and / or the engagement recess, depending on where the sensor is located. The sensor is set up to detect a presence and / or a direction of movement of an object in the associated monitoring area. If the sensor has detected or detected that such an object is moving towards the wing or the engagement recess, the sensor transmits a corresponding sensor signal to the activation circuit. Due to this signal, the drive circuit is caused to move the latch in the unlocked position, thus releasing the associated wing in its movement. This allows the completely non-contact operation of the lock according to the invention; it does not even have to be pressed a switch. The sensor may be located at a desirable location, for example, in or on a wall. It can also be set so that its surveillance area monitors, for example, a hemisphere with a radius of 10 cm around the sensor. This minimizes the risk of a false trip or Fehlentriegelung.

Preferably, the drive circuit is only caused to move the latch in the unlocked position when the latch is not in Unlocking position is located. This prevents unnecessary triggering of the drive mechanism, associated with increased energy requirements over time and the risk of damage, in particular electrical components of the drive mechanism, for example in the form of a "burn-through".

The sensor system preferably comprises at least one presence sensor and / or a motion sensor. Presence sensors allow the detection of the presence of objects such as persons, and motion sensors can react to movements of such objects or even detect their direction of movement. Presence sensors allow a reaction when the subject is near the sensor, but moving very slowly or not at all. Motion sensors allow to filter out whether a person is moving back and forth in a room, or whether they want to open the respective wing, for example, and possibly pass. A combination of both types of sensors increases detection reliability, and one type of sensor failure can be partially compensated for by the other. In any case, a total failure is avoided. Several sensors also enable a higher-level monitoring circuit, which can detect a sensor defect and then display or send a warning. Overall, the reliability of the lock increases. Another advantage is that due to the presence sensor fast movements can be detected on the motion sensor and away again and thus a false triggering can be avoided again. In addition, the problem can be solved that the wing is not mistakenly locked permanently. For example, if a person moves from one side to the wing and activates the lock, it could happen that the lock remains activated even though no person is in the area of the wing or by way of example of a space to be closed by it. This would mean that the lock would not unlock. Due to the presence sensor, the lock or its control electronics can detect that there is no person at all in the area of the wing or in the area to be monitored, and the locking can release the wing again.

The lock according to the invention preferably further comprises a bolt sensor. The bolt sensor is set up to at least detect whether the bolt is in the unlocked position or in the locked position or not. This allows the lock, for example, to drive the drive mechanism only when it is required.

The bolt sensor is preferably formed without contact. This makes it possible to detect the position of the bolt without any mechanical and possibly electrical contact between two parts being required to detect the position of the bolt. This avoids any problems with friction, abrasion or soiling that could affect the transmission of electrical energy across electrical contacts. This increases reliability, which benefits operational safety.

The bolt sensor preferably has a magnetic element or an element made of magnetizable material, which is fixedly arranged on at least a first predetermined point of the bolt or of a part operatively connected thereto with respect to the bolt or the actively connected part. In addition, it has a magnetic sensor which is fixedly arranged at least at a second predetermined location in the housing with respect to the housing, that the magnetic sensor detects the at least one magnetic element when the bolt is in the unlocked position or in the locked position. The magnetic sensor can be formed as a Hall sensor, reed contact or simply by means of a current-carrying conductor coil surrounding the latch. Ie. A magnetic sensor in the sense of the application is a sensor which reacts to changes in an (electro) magnetic field in its monitoring or detection range. If the aforementioned element moves past or through the magnetic sensor, this causes a change in the magnetic sensor, for example as a result of switching or a current change in the sensor conductor, whereby it can be detected that the abovementioned element is located in the detection range of the magnetic sensor. The special arrangement of element (s) and magnetic sensor finally allows the conclusion of the assumption of unlocking or locking position by the bolt. The result is a very effective and simple design sensors, which is also inexpensive and requires little space.

Additionally or alternatively, the bolt sensor comprises an optical sensor. This sensor is fixedly arranged at a predetermined position in the housing with respect to the housing, that it detects the bolt or a part operatively connected with it when the bolt is in the unlocked position or in the locking position or the part operatively connected to the bolt in one is located with the unlocking position or locking position of the bolt corresponding position. This has the advantage that any existing, electromagnetically sensitive parts, for example, the drive mechanism 'are not impaired in their function. In particular, this sensor lends itself to the latch for detecting its unlocked position when the latch is retracted into the housing.

Preferably, the aforementioned operatively connected part is inextricably operatively connected to the bolt. This means that the operative connection between this part and the latch during operation can not be solved. This non-detachable operative connection has the advantage that it can be closed in each case to the respective position of the bolt, even if the bolt sensor does not monitor the bolt itself but another part with respect to its position. As a result, the reliability improves.

Additionally or alternatively, the lock according to the invention also has an additional mechanism, for example for an emergency release. This mechanism is set up to bring the latch in the unlocked or locked position when actuated, bypassing the drive mechanism. This is advantageous in the case when the power should have failed. The latch can continue, if taken, maintain its locking position, since it can be unlocked at any time and thus moves the associated wing, for example, can be opened. This also increases the reliability. In addition, can be dispensed with elaborate security precautions.

The operation of this mechanism 'is advantageously carried out manually. As a result, the lock can be used, for example, in escape routes. Normally it is required that in case of emergency, when the power is turned off for safety reasons, in the case of a normally electrical operation a maximum of two handles are allowed to open a wing, such as a door, and to escape. The first handle includes the emergency release of the wing, and the second handle the actual opening of this wing. As a result, the lock is universally applicable. Another advantage is that a user optically finds a conventionally manually operable latch. If he approaches the lock, the bolt is automatically unlocked, for example, what the user perceives. In particular, he recognizes this by a movement of the bolt. Ie. the user learns to use the lock without additional measures such as operating instructions.

The additional mechanism is preferably realized by releasably engaging the latch with a drive member operatively connected to the drive mechanism of the latch. In addition, it comprises an actuating portion which is operatively arranged from the outside in relation to the other lock and releases the operative connection between the drive element and the bolt when actuated. The release of this operative connection allows the (manual) retraction of the bolt into the lock housing, without the need to move the drive mechanism, which could otherwise oppose the retraction of the bolt resistance.

For this purpose, the bolt is preferably latchingly engaged with the drive element. This has several advantages. First, a certain amount of force can be required to solve the operative connection to the drive element can. Second, by moving the drive member to a position corresponding to the unlatching position of the latch, the drive mechanism can be re-engaged with the latch so that the latch is ready for use again. Third, the operational readiness can be restored by moving the latch (manually) back to the locked position. Overall, the reliability improves.

The actuating portion is preferably formed by means of an actuating pin. This pin is either formed on the bolt or stationary with respect to the latch. He also protrudes from the housing protrudes and extends substantially transverse to the path of movement of the bolt. The pin thus allows the translatory movement of the bolt by the pen in a corresponding direction moves, for example, pulled, is.

The drive mechanism preferably includes an engine operatively connected to the latch with a transmission. The transmission realizes the conversion of the rotation of the engine output shaft in the translational movement of the bolt. In addition, this realization allows a determination of the bolt in the respective end position, ie in unlocking or locking position. Another advantage is that only power is consumed to move the latch to the other end position but not to hold it there. This allows the lock to be battery operated. As a result, no external wiring is required, which facilitates installation and also allows use in buildings without external electrical power supply.

Alternatively, the drive mechanism comprises an electromagnet. This has the advantage of only a very short-term energization for changing the locking position. For this purpose, the electromagnet is advantageously designed bistable.

The lock can according to the invention also have an indicator. The display should be set up when the latch is in the unlocked or locked position. For this purpose, the aforementioned bar sensor is advantageously used.

Additionally or alternatively, it can be displayed whether the wing is locked or unlocked. Ie. There is also a sensor that detects whether the wing is locked in a respective open position from the bolt or not. If the locking in the closed position of the wing, it can be provided that the main closing edge of the wing in the closed position actuates a switch, can be detected by the thus whether the wing has reached the closed position or not. If this result is logically ANDed with the result of whether the latch is in the locked position, it can be easily determined whether the blade is locked or not. In addition, it is possible to determine that the bolt must be retracted in the unlocked position in order to close the wing example.

In addition, it can be provided that the display also indicates when the wing is moved. This can be achieved by providing the blade with a magnet which, as it moves, is moved past a sensor, for example in the form of an elongate coil, inducing in the coil a voltage sufficient, for example an LED display, with energy to supply.

In extreme cases, all relevant operating conditions of the wing can be displayed separately in conjunction with the lock.

A wing system according to the invention has at least one wing according to the aforementioned type and at least one of the aforementioned locks. The latch is arranged to be capable of locking said at least one associated wing in the open position and / or in the closed position. The locking device or the engagement recess of the respective locking is fixedly arranged on a stationary part of the wing system, and the engagement recess or the locking device is arranged fixedly on the wing. For example, the wing may be formed as a sliding leaf and have two engagement recesses, which are arranged so that one and the same lock can lock the wing in both open and closed position.

The system preferably further comprises an element with one of the aforementioned displays and can thus indicate the state of the wing.

The system also preferably has a leaf actuator, which is operatively connected to the at least one wing, upon activation to open and / or close the at least one wing. In the case of a pivoting rotary wing is a rotary leaf drive or door closer; in the case of a sliding door system to a sliding door drive, in the case of a partition to a respective partition module drive, etc. D. h. the lock can be used on any type of movable / wing / n system.

The latch is preferably coupled to the blade actuator such that the drive circuit of the at least one latch, after transferring the latch into the unlocked position, causes the blade actuator to close or open the blade from the open or closed position. This effectively prevents the wing actuator from attempting to move the wing, although it is still locked. This improves the operational safety of the entire system.

The wing system according to the invention preferably also has a sensor coupled to the drive circuit. This sensor is designed or arranged such that the drive mechanism of the lock is only caused to move the latch in the locked position, when the latch and associated engagement recess are arranged to each other so that the latch engages in the locking position in the engagement recess. This prevents the sash from being moved in the direction of the extended bolt and hits it, possibly damaging it. This also increases the reliability of the system.

The system preferably also has an activation sensor system associated with the at least one wing. This activation sensor is designed like the aforementioned sensor coupled to the drive circuit. It is also coupled to the wing actuator in such a way that the activation sensor system transmits a signal to the wing actuator when the presence of an object or detected movement direction of the object on the wing causes the wing actuator to open the wing, if not already done. This allows a safe, automatic opening of the wing.

The activation sensor is preferably coupled to the latch of the associated, at least one wing. When detected presence of an object or detected direction of movement of the object on the wing, it now transmits a signal to the drive circuit of the locking of the associated wing. The drive circuit then causes the drive mechanism, if not done yet, to move the latch in the unlocked position. Only when the latch is in the unlocked position, which in turn is detected by sensors, the drive circuit transmits a signal to the wing actuator, which causes the wing actuator, if not done, to open the wing. This ensures that the wing is not opened by the wing actuator when the latch is not in unlocked position.

The plant can be exemplified as a wet room, toilet cubicle and / or locker room. This results from the fact that no part of the wing system must be touched.

1a shows an example designed as a double toilet cabin wing system 1 , It includes for each individual cabin designed here as a sliding door wing wings 2 , the example of not designated, arranged above fittings in a support profile or fighters 3 suspended and guided guided along the direction indicated by block arrows directions. The left sliding door wing 2 is shown partially open, whereas the right sliding door leaf 2 closed is. Between the sliding door wings 2 is an immovable festival wing 4 arranged. Ie. the sliding door leaves 2 when opening behind the fixed wing 4 method. The carrier profile 3 is on two outboard poles 9 attached. Furthermore, the fixed wing obscures 4 two middle pillars 9 in the direction of loading behind the fixed wing 4 in the lower area preferably hold a non-visible floor guide rail, which is the sliding door 2 . 2 in the lower area leads. Every sliding door wing 2 here by way of example comprises a recessed grip in the area of the respective main closing edge 8th which involves a manual opening of the respective sliding door leaf 2 allows. Furthermore, extend from the carrier profile 3 outgoing two partitions 7 in the direction of the wing system 1 , which are exemplified by framed fixed wing. They come across their carrier profile 3 opposite end faces against a rear wall 6 on the right side wall 5 abuts, at the right post 9 is appropriate. Further, located at the outer posts 9 display devices 300 , which will be described later.

1b shows the right post 9 from 1a , It can be seen that on one of the main closing edge of the sliding door leaf, not shown here 2 facing side of this post 9 a lock 100 attached, which will also be explained later.

1c shows this post 9 enlarged in the clipping. The lock 100 and the ad 300 can be seen more clearly here. A cover 210 a case not designated here 200 the lock 100 indicates at its the sliding door wing 2 facing side a passage opening 211 on, which, as described in more detail later, the passage of a bolt 111 serves. The sliding door wing 2 indicates to its the lock 100 facing side at least one recess which is arranged so that the bolt 111 when in the direction of sliding door leaves 2 extended, so here exemplary in the closed position of the sliding door sash 2 , engages in the recess. This is the sliding door wing 2 locked in its movement here in the opening direction and locked with it.

2a shows the lock 100 individually, 2 B in greater detail, in partial exploded view. As can be seen, there is the aforementioned housing 200 essentially from a base part 220 in which all functional elements of the lock 100 are received and attached, and one on the base part 220 pushed and, for example, by means of clamping or Verrastens attached thereto cover 210 , which is designed as an example as a U-profile. This has the advantage of the cover 210 to be able to produce extruded profile and then simply cut to length at the desired locations, which allows a very cost-effective production. In addition, the cover 210 so on basic parts 220 different heights are easily adjusted.

The access opening 211 for the bar 111 is clearly visible. Further, the cover has 210 at its the base part 220 opposite side approximately in the middle a second passage opening 212 on. Between the cover 210 and the base part 220 is a sensor holder 133 arranged. This points here on two sides towards the base part 220 extending projections on. These projections have latching lugs at their free ends 134 on, of which only the right is visible, and the example of each other away. In the assembled state, the locking lugs engage behind 134 associated recesses 221 of the base part 220 of which only the left one is visible. Ie. the sensor holder 133 simply gets into the base part 220 pushed and due to the engagement of the locking lugs 134 with the recesses 221 kept in position. Preferably, the base part 220 additionally not designated here, groove-like recesses on the latching lugs facing sides of the base part 220 are formed, in the insertion direction of the sensor holder 133 extend and, seen in this direction, at their ends in the aforementioned recesses 221 lead. These groove-like recesses are provided, the locking lugs 134 of the sensor holder 133 lead during its insertion, which simplifies installation.

The sensor holder 133 exemplarily has two substantially rectangular passage openings 136 . 136 on. On each of these is an associated cover 131 . 141 a sensor 138 or a later explained in more detail display 140 fixed in place. Furthermore, a passage opening 135 for the bar 111 intended. The sensor holder 133 by way of example further comprises a fastening section formed here by means of a trough-like recess 137 , This has two mounting holes on the right and left 139 on, in the from the base part 220 coming associated presence sensors 132 are used, as indicated by dashed lines. The sensors 132 . 138 serve to activate one in the base part 220 received drive mechanism ' 150 the lock 100 and are therefore part of an activation sensor system 130 , A drive mechanism 150 comprises an electromechanical drive, formed here by means of an electric motor 151 , On its not visible output shaft is an example of an incremental encoder 152 placed.

Further, at one of the engine 151 opposite side of the incremental encoder 152 on the output shaft here a worm wheel 153 rotatably mounted, that with a spur gear 154 combs. At the sensor holder 133 facing, substantially transverse to the axis of rotation of the spur gear 154 extending side of the spur gear 154 there is a lead 155 pointing in the direction of the sensor holder 133 is formed protruding.

The lead 155 stands with a Mitnehmerausnehmung 162 a driver 156 engaged. The driver 156 is in the base part 220 taken translationally guided. The path of movement of the driver 156 runs approximately parallel to the orientation of the access opening 211 the cover 210 , in 2a So to the right and to the left. This is the spur gear 154 possible when rotating the driver 156 to take along, along its path of movement.

At its the recess 162 facing away from the driver 156 a lead 157 on, in a corresponding, not designated here recess 122 a bolt body 112 of the bolt 111 intervenes. The bolt body 112 is parallel to the path of movement of the driver 156 in the base part 220 led recorded. This is the driver 156 possible, during the procedure the bar body 112 and thus the bar 111 take. The bolt 111 also has a locking pin 114 on that by a guide part 125 passed through, which in turn in the base part 220 is attached.

The free end of the output shaft of the engine 151 is among other things using a pivot bearing 158 in the base part 220 fixedly arranged.

Between cover 210 and spur gear 154 is at the cover 210 side facing also a stop part 165 arranged. This is exemplified by mounting screws 166 preferably on the base part 220 attached and extends here, along the axis of rotation of the spur gear 154 seen over the entire spur gear 154 time. The stop part 165 is arranged so that it is in the path of movement of the projection 155 protrudes. This limits the stop part 165 the path of movement of the Mitnehmervorsprungs 155 and thus the rotation path of the spur gear 154 , In addition, this can be prevented that driver projection 155 and recess 162 disengage each other.

2c shows the drive mechanism 150 in greater detail. All other parts are omitted. The motor 151 is an example of the incremental encoder 152 attached, in turn, on a holding part 159 for example screwed. With this form engine 151 and incremental encoder 152 an assembly unit, made as a whole and on the holding part 159 can be attached. The incremental encoder 152 indicates to his the engine 151 opposite side preferably a bearing 167 on, about that the output shaft of the engine 151 in the holding part 159 is recorded freely rotatable. The worm wheel 153 is thus between two camps 158 . 167 arranged. Also the camp 158 is in the holding part 159 preferably clamped stationary. As 3c shows is the spur gear 154 about a camp 168 also in the holding part 159 freely rotatable recorded. Ie. This entire arrangement can be used as a drive module in the base part 220 be used, which enormously simplifies the assembly.

Furthermore, it is clear the engagement between the spur gear 154 or his pen 155 and takers 156 or recess 162 to recognize. To minimize friction is the driving pin 155 provided with a non-designated bearing, which is a metal ring in the simplest case.

It is also clearly recognizable, as a driver 156 and bar body 112 over the lead 157 and the recess 122 be in driving engagement. It can also be seen that the driver 156 in the area around the projection 157 around a slot-like passage opening 163 advantageously along the path of travel of the driver 156 extends. This allows the driver 156 in the area of the slot 163 dodge up here, though this is the lead of the base part 220 not allowed. This allows the bar body 112 , the lead 157 to be able to drive under. Ie. locking body 112 or bar 111 and lead 157 or driver 156 can be disengaged by the bolt 111 can be moved, although the driver 156 due to the drive mechanism 150 is prevented from moving. Are there bars 111 and takers 156 out of engagement, the driver can 156 due to the engine 151 in the direction of the bolt 111 be moved, that both parts engage again with each other.

3a shows the bar 111 in greater detail as an exploded view. The bolt body 112 is hollow inside along its longitudinal extent. In this cavity is the aforementioned locking pin 114 inserted. The bolt body 112 has on a longitudinal side a preferably transversely to the longitudinal extent extending passage opening 118 on. The passage opening 118 is preferably formed as a sink hole. Furthermore, the Mitnehmerausnehmung 122 to recognize.

The locking pin 114 here has two openings threaded openings 116 , So openings with internal thread, on, one in the assembled state with the through hole 118 flees. Further, an actuating pin 113 shown using an externally threaded portion 117 in one of the threaded holes 116 is screwed. Preferably, the actuating pin 113 on a the bolt body 114 remote end of the male threaded portion 117 an annular protruding portion 123 on, pointing towards male thread section 117 essentially complementary to the sinkhole 118 rejuvenated. This will be the actuating pin 113 when inserted into the bar body 112 centered, which simplifies assembly. In addition, operating pin clamp 113 and latch pin 114 the bolt body 112 a, so that all parts are securely fastened together.

Preferably, the section 123 a maximum outer diameter greater than a dimension of the passage opening 135 transverse to the path of movement of the bolt 11 is. The section 135 is located between the base part 220 and the sensor holder 133 so from the sensor holder 133 in the base part 220 is held and can not be removed. This serves the manipulation security of the lock 100 ,

The locking pin 114 can be from the right, as shown, or from the left into the bar body 114 be pushed in and tightened. Ie. depending on the attachment of the locking pin 114 to the right or to the left from the housing 200 protrude.

At one here the actuating pin 113 opposite side of the bolt body 114 are preferably two magnets 115 used. These serve, as explained later, the detection of the locking position in the base part 220 ,

The bolt body 112 also has externally disposed or formed, along the path of travel extending guide portions 119 here in the form of protrusions 119 on. These serve to guide the bolt 111 in the base part 220 ,

3b shows the bar 111 from one regarding 3a opposite side. As can be seen, the threaded openings 116 in the locking pin 114 preferably formed continuously. This simplifies the assembly. Furthermore, it can be seen that the guide sections 119 are formed by Eckausnehmungen, between which two guide projections 121 are formed. These can be achieved by a single, continuous projection 121 be replaced. In the projections 121 are reception openings 120 formed, in which the magnets 115 preferably with the locking body 112 are inserted flush.

3c shows the lock 100 in another exploded view. The base part 220 preferably has a receptacle on two opposite sides 225 for the leadership part 125 on. This has a passage opening 124 for the locking pin 114 on. The guide part 125 also has two facing away from each other, transverse to the passage opening 124 extending projections 126 on. These here in the area only the back half of the guide part 125 educated. The base part 220 has accordingly in the field of recordings 225 here in the rear area corresponding, stepped sections on which are not visible here. During assembly, the guide part 125 of the Back of the base part 220 towards the sensor holder 133 pushed in and comes with the tabs 126 Can lie on the stepped sections and therefore can not forward from the base part 220 be removed. This is also the bar body 114 safe in the base part 220 held. This has the advantage of possibly moving the grand piano 2 despite locking causes that at the lock 100 occurring forces in the base part 200 and not for example in the cover 210 be directed.
