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 that is movable relative to the frame.
  • the closure comprises a base body designed for attachment to the frame or to the sash and a closure element rotatably mounted on the base body, which defines a holding receptacle for a locking element attached to the sash or to the frame and which is between a release position which releases the locking element in an opening direction of the sash and a the locking element is movable in the blocking position blocking the opening direction.
  • the closure comprises a locking slide, which is guided on the base body so as to be displaceable between a locking position and an unlocking position and is biased towards its locking position by at least one spring. Furthermore, it is provided in the closure that the locking carriage in the locking position prevents movement of the closure element from the blocking position into its release position and in its unlocking position allows movement of the closure element between the blocking position and the release position.
  • a closure with the features of the preamble of claim 1 is from the EP 3 502 386 A1 known.
  • Such locks are generally used to lock or unlock windows, doors, gates or the like.
  • the base body serving as a housing for the individual mechanical components of the closure can be provided for attachment to the frame and the locking element can be provided 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 the sash.
  • the locking element can be a simple pin, in particular a rolling 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 head 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 the frame enters the holding receptacle of the locking element during a closing movement of the sash, so that the locking element is forced into its blocking position by the locking element in the course of the closing movement of the sash, in which it is then pushed by the Locking carriage is secured in such a way that the closure element cannot return to its release position. Because the closure element is automatically moved into its blocking position when the sash is closed and the sash is already prevented from opening again in this state of the closure, the sash is secured against unwanted opening immediately after the closing process, even if it the user merely gave a slight “nudge”.
  • the locking carriage In order to be able to open the sash again, the locking carriage must be actively moved back into its unlocking 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 described security function of the bolt slide may be desirable to have the described security function of the bolt slide to at least partially override. For example, if a certain pressure or tensile force is exerted on the sash, the sash should be able to be opened after overcoming a certain holding resistance without having to actively move the locking slide into its unlocking position and thus actively release the closure element. However, the door should be secured against unintentional opening, for example due to gusts of wind. If, on the other hand, a sufficiently large force is exerted on the sash, the locking element should automatically move from its blocking position back into its release position while overcoming the holding resistance, so that the sash can be opened without having to actively move the locking slide back into its unlocking position.
  • This functionality is also referred to here as a tag function or as a conditional backup. From the EP 3 026 201 A1 and the DE 10 2010 049567 A1 Closures are known which have such a tag function.
  • the invention is therefore based on the object of further developing a closure of the type described above in such a way that it enables the sash to be opened if necessary, without having to actively move the locking slide into its unlocking position in advance as part of an upstream actuation step.
  • This object is achieved according to a first aspect with a closure with the features of claim 1 and in particular in that the locking carriage has an intermediate position between the locking position and the unlocking position, referred to here as the day position, in which the locking slide is between the blocking position as a result of a movement of the closure element and the release position can be deflected in the direction of the unlocking position by overcoming the spring force of the spring.
  • the closure element If, for example, a relatively small force is exerted on the closure element via the wing due to a gust of wind, the closure element is still held in its blocked position by the locking slide in the desired manner, provided that the force resulting from the gust of wind does not overcome the holding resistance results from the spring force of the spring. If, on the other hand, a sufficiently large force is exerted on the wing, this is transferred to the locking carriage via the closure element of the closure, so that it is deflected in the direction of its unlocking position against the spring force of the spring and thus releases the closure element.
  • the closure element can therefore automatically move from its blocking position into its release position without the locking slide having to be specifically moved towards its unlocking position in an upstream actuation step.
  • the locking element In the daytime position of the locking slide, the locking element is held in its blocking position in the desired manner to prevent unintentional opening of the sash, whereas the locking element can be moved into its release position with correspondingly large opening forces acting on the sash, without unlocking the locking slide in advance to have to.
  • 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 movable relative to the frame.
  • This closure also includes a base body designed for attachment to the frame or to the sash and a closure element rotatably mounted on the base body, which defines a holding receptacle for a locking element attached to the sash or to the frame and which is between a release position which releases the locking element in an opening direction of the sash and a blocking position that blocks the locking element in the opening direction can be moved.
  • the closure comprises a locking slide, which is guided on the base body so as to be displaceable between a locking position and an unlocking position and is biased towards its locking position by at least one spring. Furthermore, it is provided in the closure that the locking carriage in the locking position prevents movement of the closure element from the blocking position into its release position and in its unlocking position allows movement of the closure element between the blocking position and the release position.
  • the locking carriage has an intermediate position between the locking position and the unlocking position, referred to here as the day position, in which the locking slide, as a result of a movement of the closure element, between the blocking position and the release position while overcoming the Spring force of the spring can be deflected in the direction of the unlocking position.
  • a handle that is coupled to it in a driving manner such as a door handle or the like, can be provided, by actuating which the locking carriage can be moved between its respective positions.
  • the closure comprises a motor arranged on the base body, which is drivingly coupled to the locking carriage in such a way that it approaches or approaches the unlocking position depending on the direction of rotation of the motor removed from it.
  • the user therefore does not have to apply the force to move the locking carriage himself.
  • no operation of a rotary handle or the like is required.
  • the installation of such a lock is relatively easy because the motor is integrated into the lock and therefore no mechanical coupling of the locking carriage with a fitting gear is required.
  • the motor can be designed as a linear motor. According to a further embodiment, however, it can be provided that the motor has a rotatably drivable output shaft which is drivingly coupled to a spindle drive which converts the rotational movement of the output shaft of the motor into a displacement movement of the locking carriage.
  • 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 motor and a spindle nut which carries the locking carriage and is thus drivingly coupled to it in order to bring about the desired displacement movement of the locking carriage.
  • the locking carriage is coupled to the spindle nut in such a way that the locking carriage can be deflected in its day position relative to the spindle nut in the direction of the unlocking position while overcoming the spring force of the spring.
  • the locking carriage is therefore not rigidly coupled to the spindle nut; rather, the locking carriage can move relative to the spindle nut to a certain extent in the axial direction of the drive spindle.
  • the deflection of the locking carriage relative to the spindle nut or vice versa can be limited by two stops spaced apart from one another in the axial direction of the drive spindle. So if the spindle nut moves relative to the locking carriage as a result of an actuation of the drive spindle by the motor, the movement of the spindle nut is only transmitted to the locking carriage when the respective stop is reached. Only from this point on is the movement of the spindle nut transferred to the locking carriage.
  • the locking slide In the daytime position of the locking slide, however, the locking slide is in any case not in contact with the stop that prevents the locking slide from moving in the direction of its unlocking position or which the spindle nut abuts against in order to move the locking slide into its locking position, otherwise the locking slide will not could be deflected in the direction of its unlocking. Rather, the stop in question has no 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 by which the locking carriage is biased towards its locked position, can be supported on the one hand on a locking carriage and on the other hand on a part that is immovable relative to the base body, or on a part fixed to the housing; According to a preferred embodiment, however, it can be provided that the at least one spring is supported on the one hand on the locking carriage and on the other hand on the spindle nut.
  • the effective length of the at least one spring can be kept small, since the spring moves together with the structural unit consisting of the spindle nut and locking carriage.
  • the length of the spring is therefore independent of the position of the structural unit consisting of the locking carriage 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 carriage and on the other hand on the spindle nut.
  • the closure element can have a closed position, with the blocking position being between the closed position and the release position.
  • the locking carriage 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 can be firmly clamped against it or a seal provided thereon .
  • the sash is secured to the frame with play in the blocking position of the closure element, which enables a certain amount of gap ventilation, the sash, on the other hand, is firmly clamped to the frame or to a seal provided along the same in the closed position of the closure element, as is the case for safety reasons or for the benefit of Thermal protection may be desirable.
  • the locking carriage can have a locking position, with the locking position being between the locking position and the unlocking position.
  • the locking carriage can therefore be moved from its unlocking position beyond its locking position into the locking position.
  • the locking carriage and the locking element cooperate in a driving manner in such a way that the locking element is forced into the closed position when the locking slide moves from its locking position into its locking position. If the locking carriage is moved from its locking position into the locking position by means of the spindle drive, this also results in the locking element being moved into its closed position and secured in this position due to the self-locking of the spindle drive.
  • 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, via which the locking carriage and the closure element interact in a driving manner stand.
  • the gear element is a two-armed lever
  • the locking carriage engages on the longer lever arm and the locking element on the shorter lever arm, whereby the reduction can be further reduced by the spindle drive, so that even smaller or weaker motors can be used can come.
  • the locking carriage and the closure element can interact in a driving manner via the gear element in such a way that the locking carriage is in its normal position as a result of a movement of the closure element can be deflected between its blocking position and its release position in the direction of the unlocking position while overcoming the spring force. Any movement of the closure element is therefore transmitted to the locking carriage via the gear element, so that it is deflected in the direction of its unlocking position when the closure element is moved back and forth between its blocking position and its release position.
  • the locking carriage and the locking element can interact in a driving manner via the gear element in such a way that the locking element assumes the closed position when the locking slide moves from its locking position into its locking position.
  • the movement of the locking slide is therefore transmitted to the locking element via the gear element, so that it is forced into its closed position when the locking slide is moved from its locking position into its locking position.
  • the locking carriage has a locking cam which, in the locking position of the locking carriage, engages behind a sliding cam formed on the closure element or on the gear element in such a way that movement of the closure element from its blocking position into its release position is prevented.
  • the locking cam of the sliding carriage can have a sliding surface that is at least partially convexly curved and/or designed as a ramp, which in the day 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 closure element moves from its blocking position into its release position, the counter sliding surface slides along the sliding surface while overcoming the spring force of the spring in the direction of the unlocking position, which is due to the at least Convex curvature in sections and/or the ramp-like shape of the sliding surfaces leads to a deflection of the locking carriage in the direction of its unlocking position. Due to the at least partially convex and/or ramp-like shape of the two cams, a kind of snapping effect is achieved when the sliding cam slides along the locking cam. The closure element is therefore able to snap between its release position and its blocking position in the day position of the locking slide, being conditionally secured by the locking slide both in the release position and in the blocking position.
  • the closure can have a coupling lever via which the closure element is coupled to the locking carriage in a driving manner, the coupling lever being articulated both on the locking carriage, in particular on its locking cams, and on the gear element, in particular on its sliding cams.
  • the gear element is rotatably mounted on the base body, and since, on the other hand, the coupling lever is articulated both with the locking carriage and with the gear element, a change in the position of the articulation point of the coupling lever on the locking carriage results in the alignment of the coupling lever with respect to the Direction of movement or with respect to the axial direction of the drive spindle changes.
  • the locking slide moves from its locking position into its locking position, the distance between the two articulation points measured transversely to the direction of movement of the locking slide increases, at which the coupling lever is articulated on the locking slide and on the gear element.
  • the coupling lever With increasing axial displacement of the articulation point of the coupling lever on the locking carriage, the coupling lever is deflected and thus the gear element and the closure element are pivoted.
  • the coupling lever is therefore a toggle lever, as its leverage changes with increasing deflection. Therefore, if the locking carriage is moved into its locking position, the coupling lever is increasingly deflected, so that with increasing deflection of the coupling lever, ever greater forces or torques act on the gear element and thus on the closure element. In order to be able to close the sash or pull the closure element into its closed position, due to the toggle lever mechanism explained, no excessively powerful motors are required in order to be able to generate the required torque to close the sash.
  • the articulation point at which the coupling lever is articulated on the locking cam can have an elongated hole guide extending in the direction of the displacement path of the locking carriage and an elongated hole guide guided therein Include pivot pins, so that the locking carriage can carry out an idle stroke movement within certain limits, which is not transmitted to the coupling lever and thus to the closure element.
  • the locking carriage can thus be moved from its unlocking position to its day position without the locking element being pivoted from its release position into its blocking position. Likewise, the locking carriage can be moved from its day position towards its locking position without the position of the locking element changing. Due to the elongated hole guide, the closure element remains in its blocking position when the locking slide is moved from its day position towards its blocking position.
  • the closure can be operated by a motor, so that no handle is required to operate the closure is needed.
  • the closure can be locked and unlocked using an emergency actuation mechanism according to a further embodiment.
  • an 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 for emergency actuation of the closure from outside the base body.
  • an emergency opening tool can be provided which has a shaft which can be inserted through the opening into the base body and forms a drive worm which engages in a driving manner into the external toothing in question.
  • the spindle drive can therefore be operated manually using the emergency opening tool, so that the closure can still be operated even in the event of a power failure or motor failure.
  • the closure can have a return spring, through which the closure element is biased in the direction of the release position. If the locking carriage is moved into its unlocking position and thus releases the closure element, it can automatically move into its release position due to the biasing effect of the spring in question.
  • the motor can be designed as an electric motor, wherein an electrical energy storage device, in particular a battery or accumulator arrangement, can be provided on the base body to supply energy to the electric motor.
  • an electrical energy storage device in particular a battery or accumulator arrangement
  • a closure 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, via which the closure can be inductively coupled to an energy source for energy supply.
  • the shutter can be inductively coupled to a signal source via the induction coil for data transmission. The shutter can therefore be mounted anywhere on a sash, as no wiring is required for the power supply or data transmission.
  • a ramp section can be formed on the locking carriage and/or on either the locking element or the gear element, by the effect of which the locking element is pushed from its locking position into its locking position into the closed position when the locking slide moves becomes.
  • the locking cam of the locking carriage can form the ramp section in question, so that it deflects the sliding cam of the gear element when the locking carriage is moved from its locking position into its locking position.
  • the gear element and thus the closure element are pivoted so that it can be clamped into its closed position by the wedge effect of the ramp section.
  • the Fig. 1 shows a top view of a closure 10 according to the invention, which has an elongated base body 12 which accommodates the individual components of the closure 10 and thus serves as a type of housing.
  • the base body 12 has two side walls 13 that are opposite one another and run in the longitudinal direction of the base body 12 (see also the Fig. 6 ), between which the individual components of the closure 10, described in more detail below, are arranged.
  • the base body 12 has a relatively small width and depth and can therefore be mounted in a fitting groove of a wing to be secured by means of the closure 10.
  • a claw-shaped closure element 14 is mounted on the base body 12 so that it can pivot about a pivot axis 15.
  • the closure element 15 has a receptacle 16 in the form of a groove open on one side, the width of which is dimensioned such that a cylindrical locking element (not shown) fits into it, which is intended for attachment to the sash of the window or door.
  • the base body 12 is designed for attachment to the wing and the locking element is designed for attachment to the frame.
  • the closure element 14 On the side opposite the holding receptacle 16, the closure element 14 has a toothing 17 which meshes with a toothing 18 which is formed on a gear element 19 which is pivotally mounted on the base body 12 about a pivot axis 11.
  • the gear element 19 On the side opposite the toothing 18, the gear element 19 forms a projection 20, also referred to here as a sliding cam, the function of which will be discussed in more detail below.
  • the closure 10 has a locking carriage 21 which can be moved in the longitudinal direction thereof and which forms a locking cam 22 on the side facing the gear element 19, which interacts with the sliding cam 20, as will also be explained in more detail below.
  • the closure 10 has an electric motor 23 arranged on the base body 12, which is coupled to the locking carriage 21 in such a way that it can move in different directions depending on the direction of rotation of the motor 23. More specifically, the motor 23 drives a drive spindle 24 of a spindle drive 25, with the rotation of the drive spindle 24 causing a spindle nut 26 arranged thereon to be moved in the longitudinal direction of the drive spindle 24 in a manner known per se.
  • the locking carriage 21 is supported on the spindle nut 26 so that it can be moved in different directions together with the spindle nut 26 depending on the direction of rotation of the drive spindle 24.
  • the closure 10 has an energy storage device such as a battery arranged under a cover 27. Additionally or alternatively, the closure 10 can also have an induction coil 39, which is also located under the cover 27 (only in the Fig. 1 indicated schematically), via which the closure 10 can be inductively coupled to an energy source to supply energy to the electric motor 23.
  • the energy supply to the electric motor 23 could also be wired.
  • Fig. 1 can be removed in turn, the locking slide 21 is supported on the spindle nut 26 via two springs 28, so that the locking slide 21 can be deflected against the spring force of the springs 28 when the spindle nut 26 is fixed relative to the spindle nut 26.
  • the spindle nut 26 can be moved relative to the same when the locking carriage 21 is stationary.
  • the relative mobility between the spindle nut 26 and the locking carriage 21 is limited by two stops spaced apart from one another in the axial direction of the drive spindle (not visible), so that the locking carriage 21 can be taken along by the spindle nut 26 after the respective stop has been reached.
  • the two springs 28 are supported on the one hand on the locking carriage 21 and on the other hand on the spindle nut 26; Alternatively, it is also possible for the springs 28 to be supported on the one hand on the locking carriage 21 and on the other hand on a part fixed to the housing.

  • a locking element located on the sash of a window to be secured can slide into the holding receptacle 16, whereupon the closure element 14 continues to move clockwise in the direction of the closing movement of the sash Fig. 4 shown blocking position B of the closure element 14 is pivoted.
  • the closure element 14 is biased towards its release position F by means of a return spring, not shown here, whereby this spring can act either directly on the closure element 14 or on the gear element 19 and thus indirectly on the closure element 14.
  • the locking carriage 21 in advance by energizing the motor 23 using the spindle drive 25 Fig. 2 to transfer to the waiting position W shown, in which the locking cam 22 is in contact with or touches a convexly curved sliding surface section of the sliding cam 20 at the end, the locking carriage 21 being elastically biased against the sliding cam 20 in this waiting position W by means of the springs 28.
  • the locking slide points between the in the Fig. 4 Locking position S shown and in the Fig. 1
  • the unlocking position E shown here has an intermediate position, referred to here as the day position T, as in the Fig. 3 is shown.
  • the locking carriage 21 has the same relative position relative to the spindle nut 26 as in the locking position ( Fig.
  • the sliding cam 20 lies against a sliding surface 31 of the locking cam 22, this sliding surface 31 forming a ramp or being inclined like a ramp in such a way that the locking carriage 21 is deflected against the spring force of the springs 28 in the direction of its unlocking position E when the sliding cam 20 is pivoted in the clockwise direction due to a pivoting movement of the closure element 14 counterclockwise in the direction of its release position F. If the opening force on the closure element 14 is sufficiently large, this leads to the locking carriage 21 being deflected in the direction of its unlocking position E against the holding resistance of the springs 28 and thus enabling the movement of the closure element 14 and the closure element 19.
  • the sliding cam 20 partially moves past the locking cam 22 in a clockwise direction and slides along the end face of the same.
  • the gear element 19 initially experiences a counterclockwise torque from the locking carriage 21; Due to the convex shape of the counter sliding surface 30 of the sliding cam 20, this counterclockwise torque decreases as the gear element 19 rotates clockwise until it then increases again, but then clockwise.
  • This variation in the torque that the gear element 19 experiences through the locking carriage 21 due to the spring preload by the springs 28 leads to the closure element 14 snapping around, so that the closure element 14 is in the day position T of the locking carriage 21 has two defined end positions, namely the release position F on the one hand and the blocking position B on the other.
  • the closure element 14 can then be pivoted back into its blocking position B against the resistance applied by the springs 28, in which it is in the Day position T of the locking carriage 21 is secured to a limited extent. In the day position T of the locking carriage 21, it can thus be deflected in the direction of its unlocking position E as a result of a movement of the closure element 14 against the spring force of the springs 28.
  • the locking carriage 21 can then be temporarily moved by means of the spindle drive 25 in the direction of its blocking position S into a temporary holding position, in which it is moved by the Sliding cam 20 of the gear element 19 cannot be pushed back towards its unlocking position E.
  • this temporary stopping position is only approached for a short time in order to prevent the wing from jumping open.
  • the locking carriage 21 can then be moved back to its day position T.
  • the blocking position B of the closure element 14 is angularly oriented so that the sash does not lie tightly against the frame, so that a certain amount of night ventilation is still possible.
  • the closure element 14 can move from the release position F beyond the blocking position B into a closed position SS according to Fig. 5 can be pivoted in order to clamp the sash tightly to the frame.
  • the locking carriage 21 is started from the one in the Fig. 4
  • the locking position S shown is moved further in the direction of the gear element 19 or the closure element 14 by means of the spindle drive 25.
  • the spindle nut 26 is moved in the direction of the locking carriage 21 until the spindle nut 26 abuts the locking carriage 21, so that this is moved from its locking position S towards its locking position V as the spindle nut 26 continues to move.
  • the sliding cam 20 continues to ride on the sliding surface 31 of the locking cam 22, with the result that the gear element 19 is pivoted further counterclockwise.
  • the closure element 14 is thus pivoted clockwise into its closed position SS, whereby the wing is pulled firmly against the frame.
  • the gear element 19 acts as a reduction gear.
  • the gear element 19 can equally be replaced by a two-armed lever with lever arms of different lengths.
  • the locking carriage 21 is at least temporarily returned to its position Fig. 1 shown unlocking position E moves, in which the locking carriage 21 allows the closure element 14 to swing back into its release position F by the return spring acting either on the closure element 14 or on the gear element 19.
  • the closure element 14 is pulled towards its closed position SS by the sliding cam 20 is deflected by the ramp-shaped sliding surface 31 of the locking cam 22 when the locking carriage 21 is moved in the direction of its locking position V.
  • the gear element 19 can be coupled to the locking carriage 21 via a toggle lever mechanism, which has the effect of deflecting the closure element 14 in the direction of its closed position SS when the locking carriage 21 is moved into its locking position V.
  • This toggle mechanism includes according to the Fig. 8 and 9 a coupling lever 32, which is articulated on the one hand on the locking carriage 21, in particular on its locking cam 22, and on the other hand on the gear element 19, in particular on its sliding cam 20.
  • the articulation point at which the coupling lever 32 is articulated on the locking slide 21 is formed by a pivot pin 33 which is displaceably mounted in an elongated hole 34 formed in the locking slide 21.
  • This elongated hole guide 33, 34 allows the locking slide 21 to be deflected in the day position T in the direction of its unlocking position E, as is necessary, among other things, to implement the day function.
  • the closure 10 In order to be able to operate the closure 10 despite the self-locking property of the spindle drive 25 in the event of a power failure or in the event of a possible failure of the motor 23, the closure 10 according to the invention has an emergency actuation function, see in particular the Fig. 7 .
  • the drive spindle 24 is accessible from outside the housing 12, so that it can be operated with the help of a corresponding emergency opening tool 36.
  • an opening 35 is formed in the base body 12 through which an emergency opening tool 36 can be inserted into the base body 12.
  • an emergency opening tool 36 In order to be able to rotate the drive spindle 24 with the aid of this emergency opening tool 36, an external toothing 37 is provided on the drive spindle 24.
  • the emergency opening tool 36 has a drive worm 38 which can be inserted through the opening 35 into the interior of the housing, so that the drive spindle 24 is set in rotation by meshing engagement of the drive worm 38 with the toothing 37 by rotating the emergency opening tool 36 and thus the closure 10 can be actuated even in the event of a power failure can.
