Definitions

  • the invention relates to a closure for a window, a door or the like, the window, the door or the like having a frame and a sash which is movable relative to the frame.
  • the closure comprises a base body designed to be attached to the frame or sash and a closure element rotatably mounted on the base body, which defines a holding receptacle for a locking element fastened to the sash or the frame and which between a locking element that releases the locking element in an opening direction of the sash Release position and a locking position blocking the locking element in the opening direction is movable.
  • the lock comprises a bolt slide, which is slidably guided between a locking division and an unlocking position on the base body and is biased by at least one spring in the direction of its locking division. Furthermore, it is provided with the lock that the locking slide in the locking division prevents movement of the locking element from the blocking position into its release position and in its unlocking position allows a movement of the locking element between the blocking position and the release position.
  • the base body used as the housing for the individual mechanical components of the lock can be provided for attachment to the frame and the locking element for attachment to the wing or vice versa.
  • the base body can be designed for receiving and fastening in a fitting groove of the frame or of the sash.
  • the locking element can be a simple pin, in particular a roller pin.
  • the pin can have a cylindrical cross-section in order to enable particularly easy sliding into the holding receptacle of the closure element.
  • the pin can preferably be designed as a mushroom pin.
  • the closure element can be pivotable between its release position and its blocking position, for example about a pivot axis running transversely to the opening direction. This enables a particularly simple construction.
  • the locking element attached to the sash or frame enters the holding receptacle of the locking element in the course of a closing movement of the sash, so that the locking element is pushed into its blocking position in the course of the closing movement of the sash by the locking element, in which it is then is secured by the bolt slide in such a way that the locking element cannot return to its release position. Because the closure element is automatically moved into its blocking position by closing the sash and reopening of the sash is already prevented in this state of the closure, the sash is secured against undesired opening immediately after the closing process, even if the user just gave it a slight "push".
  • the bolt slide In order to be able to open the sash again, the bolt slide must be actively transferred back into its unlocked position, which can be done for example by operating a handle such as a door handle or an actuator such as an electric motor.
  • the security function of the Rie- at least partially override the gel slide. If, for example, a certain compressive or tensile force is exerted on the sash, the sash should be able to be opened after overcoming a certain folding resistance, without first having to actively move the locking slide into its unlocked position and thus actively release the locking element. Nevertheless, the door should be secured against unintentional opening such as gusts of wind.
  • the locking element should automatically move from its blocking position back into its release position, overcoming the folding resistance, so that the sash can be opened without having to actively move the locking slide back into its unlocking position.
  • This functionality is referred to here as a day function or as a conditional backup.
  • the invention is therefore based on the object of further developing a lock of the type described at the outset so that it enables the sash to be opened if necessary without having to actively guide the locking slide into its unlocking position beforehand as part of an upstream actuation step.
  • a lock with the features of claim 1 and in particular in that the locking slide between the locking division and the unlocking position has an intermediate position, referred to here as the day position, in which the locking slide between the locking element as a result of a movement the blocking position and the release position can be deflected by overcoming the spring force of the spring in the direction of the locking position Ent. If, for example, a relatively small force is exerted on the locking element via the wing due to a gust of wind, the locking element is still held in its blocking position in the desired manner by the locking slide, provided that the force resulting from the gust of wind does not overcome the holding resistance resulting from the spring force of the spring.
  • a closure for a window, a door or the like is proposed, the window, the door or the like having a frame and a sash which is movable relative to the frame.
  • This closure also comprises a base body designed to be attached to the frame or the sash and a closure element rotatably mounted on the base body, which defines a flap receptacle for a locking element attached to the sash or the frame and which is between a release pin that releases the locking element in an opening direction of the sash ment and a blocking position blocking the locking element in the opening direction is movable.
  • the lock comprises a locking slide, wel cher between a locking division and an unlocking position slidably guided on the base body and is biased by at least one spring in the direction of its Sperrstei development.
  • the locking slide in the locking division prevents the locking element from moving from the blocking position to its release position and, in its unlocking position, allows the locking element to move between the blocking position and the release position.
  • the locking slide has an intermediate position, here called the day position, between the locking division and the unlocking position, in which the locking slide as a result of a movement of the locking element between the blocking position and the Release position by overcoming the spring force of the spring in the direction of the Entsperrstel development can be deflected.
  • a drive-effective coupled handle such as a door handle or the like can be provided, by actuating the locking carriage between its respective positions.
  • the lock comprises a motor arranged on the base body, which is coupled to the bolt slide in such a way that it approaches the unlocked position depending on the direction of rotation of the motor or move away from it.
  • the user does not have to apply the force to move the bolt slide himself.
  • no operation of a twist grip or the like is required.
  • the assembly of such a lock is relatively simple, since the motor is integrated into the lock and therefore no mechanical coupling of the bolt slide with a hardware gear is required.
  • the motor can be designed as a linear motor. According to a more direct embodiment, however, it can be provided that the motor has a rotationally drivable output shaft, which is operatively coupled to a spindle drive that converts the rotational movement of the output shaft of the motor into a displacement movement of the bolt slide.
  • the spindle drive is preferably designed to be self-locking so that the motor can be switched off as soon as the locking element has reached the desired position after a motor-driven movement phase.
  • the spindle drive can comprise a drive spindle driven by the Mo tor and a spindle nut which carries the Rie gelschlitten and is thus operatively coupled to the locking slide in order to bring about the desired displacement movement.
  • the locking slide is coupled to the spindle nut in such a way that the locking slide in its day position can be deflected relative to the spindle nut, overcoming the spring force of the spring in the direction of the unlocking position.
  • the bolt slide is therefore not rigidly coupled to the spindle nut; Rather, the locking slide can move rela tively to the spindle nut by a certain amount in the axial direction of the drive spindle.
  • the deflection of the locking slide relative to the spindle nut or vice versa can be limited by two stops spaced from one another in the axial direction of the drive spindle. So moves the Spindelmut ter as a result of actuation of the drive spindle by the motor relative to the bolt slide, the movement of the spindle nut is only transferred to the Rie gel slide when the respective stop is reached. Only from this point in time the movement of the spindle nut is transmitted to the bolt slide.
  • the bolt slide In the daytime position of the bolt slide, however, the bolt slide does not rest against the stop that prevents the bolt slide from moving in the direction of its unlocked position or to which the spindle nut abuts to move the bolt slide into its locking division, otherwise the bolt slide could not be deflected in the direction of its unlocking te. Rather, the stop in question does not have any effect in the daytime position of the locking slide so that the locking slide can be deflected in the desired manner in the direction of the unlocking position.
  • the spring through which the bolt slide is biased in the direction of its Sperrstei development on the one hand on a bolt slide and on the other hand on egg nem part that is immovable relative to the base body, or be supported on a housed part;
  • the at least one spring is supported on the one hand on the locking slide and on the other hand on the spindle nut.
  • the effective length of the at least one spring can be kept small, since the Fe moves together with the assembly consisting of the spindle nut and locking slide.
  • the length of the spring is thus independent of the position of the construction unit of bolt slide and spindle nut with respect to a part fixed to the housing.
  • the effective spring length can thus be kept small if the at least one spring is supported on the one hand on the locking slide and on the other hand on the spindle nut.
  • the closure element can have a closed position, the blocking position being between the closed position and the release position.
  • the bolt slide allows the closure element to move between its blocking position and its closed position.
  • the closure element can therefore be moved from its release position beyond the blocking position into the closed position, in which the wing is completely fixed to the frame due to the engagement of the locking element in the holding receptacle of the closure element and firmly against this or a seal provided thereon can be braced.
  • the locking slide can have a locking position, the locking pitch being between the locking position and the unlocking position.
  • the bolt slide can therefore be moved from its unlocked position beyond its locking division into the locking position.
  • the locking slide and the locking element cooperate in a drivingly effective manner in such a way that the locking element is pushed out of its locking position into the locking position when the locking slide is moved. So if the bolt slide is transferred from its locking pitch to the locking position by means of the Spindelan drive, this also means that the locking element moves into its closed position and is secured in this position due to the self-locking of the spindle drive.
  • a certain reduction can already be achieved with the spindle drive, so that the closure can get by with a comparatively weak motor;
  • a rotatably mounted gear element such as an at least partially toothed gear or a two-armed lever can be provided on the base body according to a white direct embodiment, via which the bolt slide and the locking element interact as a driving force. If, for example, the gear element is a two-armed lever, the bolt slide engages the longer lever arm and the locking element engages the shorter lever arm, whereby the reduction can be reduced even further by the spindle drive, so that even smaller or weaker ones Motors can be used.
  • the locking slide and the locking element can be driven in interaction via the gear element in such a way that the locking slide is in its day position as a result of a movement.
  • movement of the closure element between its blocking position and its release position can be deflected in the direction of the unlocking position by overcoming the spring force. Any movement of the locking element is thus transmitted to the locking slide via the gear element so that it is deflected in the direction of its unlocking position when the locking element is moved back and forth between its blocking position and its unlocking position.
  • the bolt slide and the locking element can interact with driving action via the gear element in such a way that the locking element assumes the closed position when the bolt slide moves out of its locking pitch into its locking position.
  • the movement of the locking slide is thus transmitted via the gear element to the locking element, so that the locking element is pushed into its closed position when the locking slide is moved from its locking pitch into its locking position.
  • the locking slide has a locking cam which engages behind a slide cam formed on the locking element or on the gear element in the locking pitch of the locking slide in such a way that a movement of the locking element from its blocking position into its release position is prevented .
  • the locking cam of the slide can have a sliding surface that is at least partially convexly curved and / or designed as a ramp, which, in the daytime position of the locking slide, is in contact with a counter-sliding surface formed on the sliding cam, which is also at least partially convexly curved and / or designed as a ramp can.
  • the lock can have a coupling lever via which the locking element is effectively coupled to the locking slide, the coupling lever both on the locking slide, in particular on its locking cam, and on the gear element, in particular on its sliding cam, is hinged.
  • the coupling lever With increasing axial displacement of the articulation point of the coupling lever on the locking slide, the coupling lever is thus deflected and thus the gear element and, via this, the locking element is pivoted.
  • the coupling lever is therefore a toggle lever, since its leverage changes with increasing deflection. Therefore, if the locking slide is moved into its locking position, the coupling lever is increasingly deflected, so that with increasing deflection of the coupling lever, greater and greater forces or torques act on the gear element and thus on the closure element.
  • no excessively powerful motors are required due to the explained toggle mechanism in order to be able to apply the required torque to close the wing.
  • the articulation point at which the coupling lever is hinged to the locking cam can have a slot guide extending in the direction of the sliding path of the locking slide and a slot guide therein Include guided pivot pin, so that the locking slide can perform an idle stroke movement within certain limits that is not transmitted to the coupling lever and thus to the locking element.
  • the locking slide can thus be moved into its daytime position without the locking element being pivoted from its release position into its blocking position at the same time.
  • the locking slide can be moved from its day position in the direction of its locking pitch without the position of the locking element changing. Because of the elongated hole guide, the locking element rather remains in its blocking position when the bolt slide is moved from its day position in the direction of its locking division.
  • the lock can be operated by a motor, so that no handle for operating the Losing is needed.
  • the lock can be locked and unlocked according to a further embodiment via an emergency operating mechanism.
  • external toothing can be provided on the drive spindle and / or on the output shaft of the motor, the base body having at least one opening through which the external toothing is accessible from outside the base body for emergency actuation of the lock.
  • an emergency opening tool can be provided which has a shaft which can be inserted through the opening into the base body and which forms a drive worm which engages the external toothing in question in a driving manner.
  • the spindle drive can thus be operated manually using the emergency opening tool, so that the lock can still be operated even in the event of a power failure or a failure of the motor.
  • the closure can have a return spring, by means of which the closure element is pretensioned in the direction of the release position. If the bolt slide is moved into its unlocked position and thus releases the locking element, this can automatically move into its release position due to the pretensioning effect of the spring in question.
  • the motor can be designed as an electric motor, wherein an electrical energy store, in particular a battery or accumulator arrangement, can be provided on the base body to supply the electric motor with energy.
  • an electrical energy store in particular a battery or accumulator arrangement
  • a lock designed in this way is to a certain extent self-sufficient and, in principle, does not require any connection to other drive components. Assembly is therefore particularly easy.
  • an induction coil arranged on the base body can be provided in addition or as an alternative to the electrical energy store for supplying energy to the electric motor, via which the closure can be inductively coupled to an energy source for energy supply. Additionally or alternatively, the closure can be inductively coupled to a signal source via the induction coil for data transmission.
  • the lock can thus be mounted anywhere on a wing, since no wiring is required for the power supply or for data transmission.
  • a ramp section can be formed on the locking slide and / or on either the locking element or the gear element, through whose effect the locking element is activated when the locking slide is moved from its locking position into its locking position into the closed position is urged.

Abstract

L'invention concerne une fermeture (10) destinée à une fenêtre, une porte ou analogue, la fenêtre, la porte ou analogue présentant un cadre et un battant mobile par rapport au cadre. La fermeture (10) comprend un corps de base (12) conçu pour être fixé au cadre ou au battant ; un élément de fermeture (14) qui est monté rotatif sur le corps de base (12), définit un logement de retenue (16) pour un élément de verrouillage fixé au battant ou au cadre, et peut être mu entre une position de libération dans laquelle l'élément de verrouillage est libéré dans une direction d'ouverture (R) du battant, et une position de blocage dans laquelle l'élément de verrouillage est bloqué dans la direction d'ouverture (R) ; et un coulisseau de verrouillage (21) qui est guidé dans le corps de base (12) pour pouvoir se déplacer entre une position de verrouillage et une position de déverrouillage et qui est précontraint par au moins un ressort en direction de la position de verrouillage. Le coulisseau de verrouillage (21), lorsqu'il se trouve dans la positon de verrouillage, empêche un mouvement de l'élément de fermeture (14) de la position de blocage à la position de libération, et, lorsqu'il se trouve dans la position de déverrouillage, permet un mouvement de l'élément de fermeture (14) entre la positon de blocage et la positon de libération. Le coulisseau de verrouillage (21) présente, entre la position de verrouillage et la position de déverrouillage, une position de jour dans laquelle il peut être dévié suite à un mouvement de l'élément de fermeture (14) entre la position de blocage et la position de libération en surmontant la force de rappel exercée par le ressort en direction de la position de déverrouillage.
