The present invention relates to sealing of vertically slidable facade components, and is particularly related to a hardware for a slidable facade component, a facade system and a method for moving a slidable facade component.
In case of slidable facade components, such as horizontal sliding windows and vertical sliding windows, an opening and closing is done by translation of the facade component. Special requirements exist for the sealing between the movable element and the surrounding blind or post frame structure. In DE 2145140 A, the sash is connected to its guide rails via two pairs of support arms extending transversely to the window plane, so that the sash can be tilted into its closed position. In DE 10 2016 105064 A1, the movable sash is held on movable arms. The distance between the retaining elements and the base structure is variable to provide a variable seal for the slidable component transverse to the sliding movement. However, it has been shown that in connection with, for example, passive houses, the energy requirements for the building envelope have increased and thus also the requirements for the sealing.
It is therefore an object of the present invention to provide an improved sealing.
This is solved by the subject matter of the independent claims. Further examples are given in the dependent claims. The aspects described below also apply to the hardware for a movable facade component, to the facade system and to the method for moving a movable facade component.
According to the invention, a hardware for a slidable facade component is provided. The hardware has a guide pin arrangement for the slidable facade component, an actuating rod arrangement for transmitting an actuating force, and an actuating device. The guide pin arrangement comprises at least two guide pins for a first side of the slidable facade component and at least two guide pins for a second side of the slidable facade component opposite the first side. The drive rod arrangement comprises a first drive rod for the first side of the slidable facade component and a second drive rod for the second side of the slidable facade component. The actuating device is coupled to the drive rod arrangement to transmit the actuating force to the first and second drive rods with an actuation. The guide pins are each designed as eccentric bearing pins with an eccentrically arranged axis of rotation for rotatable attachment to the slidable facade component and are provided for engagement with a guide groove arrangement arranged in the frame area. The eccentric bearing pins are each coupled to one of the drive rods via a coupling element, and are rotatable via a longitudinal movement of the drive rods. The guide pin arrangement is designed to move the movable facade component transversely to the guide direction by the eccentric bearing pins supported in the guide groove arrangement, in order to cause the movable facade component to be pressed against a fixed frame region transversely to the guide direction.
The sliding facade component can also be referred to as a slidable component.
The term “hardware” refers to a hardware arrangement for the movable attachment of a sliding facade component.
The term “slidable facade component” refers to a component for openably closing an opening in the building envelope. The slidable facade component is, for example, a window or a door, i.e. a sliding window or a sliding door.
For example, the guide groove assembly has a first guide groove and a second guide groove.
The term “guide pin” refers to a pin projecting from the facade component that engages with a guide device to guide the facade component during sliding movement. The guide device is, for example, a guide groove.
The term “eccentric” refers to an arrangement of the pivot axis such that the guide pin protrudes to different degrees on at least one side as a result of rotation about the pivot axis.
The term “driving rods” refers to elongated elements that can be used to transmit tensile and pressing forces along the lateral edges of the facade component. In case of a window sash, for example, the driving rods are provided along the sash frames. For example, the drive rods are recessed into the sash frames.
The term “transverse to the guiding direction” refers to a direction transverse to the sliding direction of the slidable component; for example, perpendicular to the plane of the slidable component.
In an example, the eccentric bearing pins are round discs.
In another example, the eccentric bearing pins are oval or elliptical discs.
The actuating device is designed, for example, as a handle for manual actuation.
In another example, the actuating device is an actuator, for example, an electric motor or an electromagnetic actuator.
The coupling element is serves for conversion of a first translation in a first direction, i.e. linear movement along the side of the slidable component, into a rotational movement of the eccentric bearing pins which, by being supported in the guide groove, convert the rotational movement into a second translation in a second direction which is transverse, e.g. perpendicular, to the first direction.
The first direction can be referred to as the first direction of translation and the second direction can be referred to as the second direction of translation.
In an example, a slidable component of a facade system is provided with a hardware. The hardware includes a guide pin arrangement, an actuating rod arrangement, and an actuating device. The guide pin arrangement for the slidable component comprises at least two guide pins for a first side of the slidable component and at least two guide pins for a second side of the slidable component opposite the first side. The driving rod arrangement is provided for transmitting an actuating force and comprises a first driving rod for the first side of the slidable component and a second driving rod for the second side of the slidable component. The actuating device is coupled to the connecting rod assembly to transmit the actuating force to the first and second connecting rods with an actuation. The guide pins are each rotatably mounted to the slidable component as eccentric bearing pins having an eccentrically disposed axis of rotation. The guide pins are provided for engagement in a guide groove arranged in the frame area. The eccentric bearing pins are each coupled to one of the drive rods via a coupling element and can be rotated via a longitudinal movement of the drive rods. The guide pin arrangement is designed to move the slidable component transversely to the guide direction by the eccentric bearing pins supported in the guide groove in order to cause the slidable component to be pressed against a stationary frame region.
According to an example, the coupling element is designed as a detachable connection between the eccentric bearing pin and the drive rod. The coupling element can be coupled with a pin attached to the drive rod.
The bolt can be selected from a plurality of bolts, for example mushroom pins. This allows the use of common window hardware, i.e. common driving rods. In an example, it is envisioned that the window sash will be equipped with any window hardware, for example on three sides (right, left, and top center), as long as that hardware has protruding pins on the hinges. The eccentric bearing pivots and the coupling elements can then be arranged by simply fixing them. The window hardware (hinges) is thus interchangeable to a certain extent.
The detachable connection can also be referred to as connection interface.
According to an example, the coupling element and the eccentric bearing pin are integrally formed as an adapter attachment. The adapter attachment has a first portion that has a round outer contour, and a second portion that has a slot for insertion of a free bolt end. The adapter attachment has a hole arranged eccentrically to the round outer contour for rotatable attachment of the adapter attachment to a frame segment of the movable facade component.
The adapter attachment is universally applicable, as it can be coupled with different driving rod systems.
The adapter attachment can also be referred to as a sealing adapter, press-on gear or sealing gear.
According to an example, the adapter attachment is made of plastic.
According to an example, the coupling element and the eccentric bearing pin form a gear for converting a longitudinal movement of a drive rod extending parallel to the plane of the movable facade component into a movement of the movable facade component directed transversely to the plane of the movable facade component.
The longitudinal, i.e. linear, movement is converted into a rotational movement, which, due to the eccentricity of the rotatable support, causes the movement to be transverse to the plane of the slidable facade component.
The coupling element forms the connection with the driving rod. For example, the slot allows engagement of a bolt attached to the drive rod. By a distance between the point of engagement of the bolt and the rotatable attachment of the eccentric bearing pin, a leverage effect is provided with which the eccentric bearing pin can be rotated.
According to an example, the coupling element is a lever that protrudes from the eccentric bearing pin and that has a slot for engagement with a pin attached to the drive rod.
The pin is designed as a mushroom pin, for example.
Movement of the driving rod moves the pin, which in turn moves the lever. The slot serves to balance the translation and rotation, so to speak.
The pin and lever form a gear for converting a first linear driving force via the drive rods into a second linear sealing force.
According to an example, the actuation has a counter-rotating gear. With the actuation, the first drive rod and the second drive rod can be moved in the same direction with respect to the slidable component. For example, the first drive rod and the second drive rod both move downward, or both move upward when actuated in a lateral arrangement (e.g., a vertical sliding window). The first drive rod and the second drive rod move, for example, both to the right or both to the left when actuated in an arrangement at the top and bottom (e.g. in a horizontal sliding window).
According to an example, at least one of the eccentric bearing pins is formed with a locking disc having a receptacle for engagement with a locking pin provided on a fixed frame portion. In another option, the receptacle is formed as i) a continuous slot having two edge segments that can be moved into the area of the locking pin such that movement of the slidable component along the guide groove is blocked. In a further option, the receptacle is designed as ii) an entry slot with an edge segment that can be moved in front of the locking bolt in such a way that movement of the slidable component along the guide groove is blocked.
The design of the receptacle as an inlet slot or as a continuous slot are both provided as options.
In an example, the two edge segments are formed as two arcuate segments that are movable in front of the locking bolt in such a way that movement of the slidable component along the guide groove is blocked. As an option, it is provided that the locking bolt has a cross-section extending longitudinally in the guide direction.
In case of a continuous slot, for example, in addition to the end position (i.e. the closed position of the slidable component), a lock can also be provided in the intermediate position, e.g. in case of a gap ventilation position of the slidable component.
In an example, the locking disc is connected to the lever and/or the eccentric bearing pin and rotates simultaneously with the eccentric bearing pin.
The locking bolt is provided, for example, on a plate that is attachable to a post frame.
The engagement with the locking pin can also be used to press the slidable component against a stop, for example to achieve a better sealing.
According to an example, at least one eccentric bearing pin is provided on each of the first and second sides with the locking disc with inlet slot. The entry slot is formed with the edge segment on the first side as a mirror image of the entry slot with the edge segment on the second side. With the actuation, the first drive rod and the second drive rod can be moved in opposite directions with respect to the slidable component.
According to an example, there is additionally provided a locking assembly comprising a rotatably mounted rotary latch having a hook at a first end for engaging a locking plate secured to a fixed frame portion. At a second end opposite the first end, the rotary latch has a slot for engagement with a bolt attached to the drive rod.
The closure arrangement can also be referred to as a locking arrangement. The slot can also be referred to as a locking or interlocking slot. The bolt can also be referred to as a locking or interlocking bolt.
For example, the closure arrangement is provided on the upper edge area of a vertical sliding window.
According to an example, an insert is provided which is designed for engagement in the guide groove arrangement arranged in the frame region and for coupling with the eccentric bearing pin. The insert has an e.g. circular receptacle for the eccentric bearing pin and is formed with at least one outer linear longitudinal edge as a contact surface in the guide groove arrangement.
In an option, it is provided that the insert is made of plastic.
In an embodiment, the insert is made of metal, for example, die-cast aluminum.
The linear longitudinal edge means that the eccentric bearing pin does not press into the wood when it is pressed on, as the force can be better distributed.
For example, the insert is made of polyamide.
According to an example, two parallel outer linear longitudinal edges are formed.
As an option, spring regions are provided on the parallel outer linear longitudinal edges on at least one side, which project resiliently beyond an abutment region of the longitudinal edges in the direction of the cross-section of the guide groove arrangement.
As an option, the spring areas are provided to protrude in the longitudinal direction of the guide groove arrangement.
As a further option, it is provided that a spring force of the spring sections can be adjusted to set a contact pressure of the lateral cantilevers for generating a braking effect.
The spring effect is achieved, for example, by a projection of 0.5 mm. Said one, i.e. first, outer linear longitudinal edge serves to bear against one side face of the guide groove arrangement in the closed state when the slidable facade component is pressed sealingly against the fixed frame area. The other, i.e. second, outer linear longitudinal edge serves for abutting the opposite side surface of the guide groove arrangement when the slidable facade component is to be brought from the sealing position to the sliding position, i.e. when the slidable facade component is pressed away from the fixed frame area.
In accordance with the invention, a handle device is also provided. The handle device has a handle rotatably mounted between a first position and a second position through approximately 180°. The handle device further comprises an edge contour connected to the handle. The handle is connectable, for example via a square, to an actuating rod arrangement for transmitting an actuating force for a hardware according to one of the preceding examples. The edge contour has an axially projecting edge transverse to the direction of rotation and is configured to engage a fixed mating member for locking. The axially projecting edge has an elliptical contour in the direction of rotation.
The axially protruding edge, in interaction with the fixed counterpart, causes a transfer of tensile forces to attract the movable facade component to the, for example, fixed or likewise movable facade component. The edge follows an ellipse in order to take into account or compensate for the horizontal offset of the sash when pressing on.
The axially protruding edge engages, for example, after approx. 90° of rotation.
The handle allows one-handed operation. For example, the handle is designed based on historical examples.
The handle not only effects pressing and thus sealing, but also locking.
According to the invention, there is also provided a facade system having a fixed opening edge forming a facade opening. Furthermore, at least one slidable component for openably closing the facade opening is provided, as well as at least one hardware according to one of the preceding examples, and a guide groove arrangement having a first guide groove in a first edge region of the opening edge and having a second guide groove in a second edge region of the opening edge opposite the first edge region. The at least one slidable component is provided with the at least one hardware. The slidable component is movably held with the eccentric bearing pins in the first and the second guide groove in a sliding direction. The slidable component can be pressed against the fixed opening edge by the eccentric bearing pins transversely to the sliding direction.
The slidable component is held in the guide grooves by the eccentric bearing pins. When pressed, the eccentric bearing pins are supported in the guide groove so that the slidable component can be pressed against the fixed opening edge transverse to the direction of the guide grooves.
According to an example, at least one handle device is provided according to the preceding example. At least one handle device is attached to the at least one slidable component and connected to the at least one hardware to actuate the at least one slidable component.
The term “actuating” includes moving, for example up or down, or right or left. The term “actuating” includes, in particular, pressing the component to seal it in the closed state and releasing it to open it.
According to an example, the slidable component is designed as a sliding window and/or a sliding door. The first and second guide grooves run linearly.
The linear design of the guide grooves is provided as an option.
In another example, the guide groove extends in a cranked manner at least in a region where the slidable component is in an at least partially open region.
In an example, a further component is provided in addition to the slidable component. For example, the further component is a further slidable component, i.e. a further sliding window or a further sliding door. For example, two slidable components are provided.
In another example, the further component is a fixed component, for example, a fixed window, such as a fixed window sash that can be opened only for cleaning purposes, or a fixed door element.
In an option, it is provided that the further component is arranged in a different plane than the slidable component. The movable component can be moved past the other component in a flat plane at a minimum distance. Due to the offset of the pressure process, the slidable component can still provide a circumferential sealing in the closed state.
According to an example, a sealing arrangement is provided at least in a partial area between the slidable component and the fixed edge of the opening: Pressing the slidable component against the fixed frame region causes the opening to be sealed. The sealing arrangement comprises elastic seals which are at least partially compressed by the pressing action.
The provision of elastic seals is provided as an option.
The term “sealing arrangement” refers to seals between the slidable component and a frame area. The seals can be formed as profiles or folds between the edges of the slidable component and the edges of the frame area. The seals can alternatively or additionally be formed as elastic seals which are at least partially compressed by the pressing action.
In an unpressed state, for example, the slidable component can be moved freely along the sealing arrangement, i.e. spaced apart.
For example, for pressing on, the slidable component can be offset by approx. 6 mm.
According to an example, a sealing arrangement is formed at least along the first side and the second side of the slidable component, forming with the fixed opening edge a sealing plane parallel to the plane of the slidable component.
The sealing arrangement can be pressed against transversely to the plane of the slidable component.
According to an example, the slidable component is a vertically slidable component. The first side is a first vertically extending longitudinal side of the slidable component, and the second side of the slidable component is a second vertically extending longitudinal side of the slidable component. The first guide groove and the second guide groove extend vertically.
The vertically slidable component is, for example, a vertically sliding window or door.
According to an example, the sealing arrangement that can be pressed against transversely to the plane of the slidable component is provided at least along the lateral edge regions. The sealing arrangement that can be pressed on transversely to the plane of the slidable component is provided in an upper edge region. In a lower edge region, a sealing is provided which can be pressed against a lower edge region in the vertical direction.
The sealing arrangement in the upper edge area is provided as an option. The formation of a sealing at the lower edge is provided as an option.
In an example, the press-on sealing assembly comprises a sealing that is attached to the vertically slidable component and that is pressed against a stop of the fixed opening rim when the vertically slidable component is closed.
In another example, as a wind driven rain sealing, a second sealing is additionally provided laterally, which is attached to the fixed opening edge and, in the closed state, is pressed against an edge region of the vertically slidable component.
In another example, the press-on sealing assembly includes a sealing that is secured to a stop of the fixed opening edge and that is pressed against an edge portion of the vertically slidable component when the vertically slidable component is closed.
According to an example, the slidable component is a horizontally slidable component. The first side is a horizontally extending lower side of the slidable component, and the second side of the slidable component is a horizontally extending upper side of the slidable component. The first guide groove and the second guide groove extend horizontally.
The horizontally slidable component is, for example, a horizontal sliding window or a horizontal sliding door.
According to an example, at least one of the eccentric bearing pins has a radially protruding projection on each side. A stop element is formed in the guide groove on one side of the groove, with which the radially projecting projection can be engaged by rotating the eccentric bearing pin. This allows the eccentric bearing pin to be supported on the stop element in order to effect a secondary pressing action parallel to the guide direction.
The secondary pressing, for example, causes the lower section of a vertically movable component to be pressed down.
The pressing of the slidable component transversely to the guide direction can also be referred to as a primary press-on.
In an example, a method is provided for moving a slidable component comprising a hardware according to one of the above examples.
In accordance with the invention, there is also provided a method for moving a movable facade component. The method comprises the following steps:
Guiding a slidable component by engaging guide pins designed as eccentric bearing pins in a guide groove arrangement; the slidable component is designed for openably closing a facade opening formed by a fixed opening edge. At least two guide pins are provided for a first side of the slidable component and at least two guide pins are provided for a second side of the slidable component opposite the first side. The guide groove arrangement has a first guide groove in a first edge region of the opening edge and a second guide groove in a second edge region of the opening edge opposite the first edge region. The eccentric bearing pins are each rotatably mounted on the slidable component with an eccentrically arranged axis of rotation and are in engagement with one of the guide grooves.
Actuating an actuating device coupled to drive rods; actuation of the actuating device causes longitudinal movement of the drive rods. The eccentric bearing pins are coupled to the drive rods via coupling elements and the longitudinal movement of the drive rods causes rotation of the eccentric bearing pins.
Rotating the eccentric bearing pins within the guide groove by the actuation of the actuation device; and thereby
Pressing the slidable component against a fixed frame region transversely to the guide direction and moving the slidable component transversely to the guide direction.
In an option, the locking solutions are provided independently of the design of the eccentric bearing pins, i.e. without the eccentric bearing pins.
In an example, a hardware for a slidable facade component is provided, which has a guide pin arrangement for the slidable facade component with at least two guide pins for a first side of the slidable facade component and at least two guide pins for a second side of the slidable facade component opposite the first side. The hardware further comprises an actuating rod arrangement for transmitting an actuating force, comprising a first actuating rod for the first side of the slidable facade component and a second actuating rod for the second side of the slidable facade component. The hardware further comprises an actuating device coupled to the drive rod arrangement for transmitting the actuating force to the first and second drive rods with an actuation. The guide pins are provided for engagement with a guide groove arrangement disposed in the frame portion. At least one of the guide pins per side is formed as a locking pin with a locking disc having a receptacle for engagement with a locking bolt provided on a fixed frame portion. The locking pins are each coupled to one of the drive rods via a coupling element and are rotatable via a longitudinal movement of the drive rods.
In an example, the receptacle is formed as a continuous slot with two edge segments that are movable into the area of the locking pin such that movement of the slidable component along the guide groove is blocked.
In another example, the receptacle is formed as an entry slot with an edge segment that is movable in front of the locking pin such that movement of the slidable component along the guide groove is blocked.
In an example, at least one locking pin is provided on each of the first and second sides with the locking disc with inlet slot. The entry slot with the edge segment on the first side is formed as a mirror image of the entry slot with the edge segment on the second side. With the actuation, the first drive rod and the second drive rod are movable in opposite directions with respect to the slidable component.
In accordance with an aspect of the invention, a guide for a slidable facade component is provided which allows movement of the slidable facade component transversely to the sliding direction by an eccentric.
It should be noted that the features of the embodiments of the hardware also apply to embodiments of the facade and the method, and vice versa. In addition, those features can also be freely combined with each other where this is not explicitly mentioned.
In the following, examples of embodiments of the invention are described in more detail with reference to the accompanying drawings.
In
The design of the slidable component as a sliding window is provided as an option. In another option, the slidable component is a sliding door.
The guide pin arrangement 12 comprises at least two guide pins 18a for a first side of the slidable facade component and at least two guide pins 18b for a second side of the slidable facade component opposite the first side. The drive rod arrangement 14 comprises at least one first drive rod 20a for the first side of the slidable facade component and a second drive rod 20b for the second side of the slidable facade component.
The actuating device 16 is coupled to the drive rod assembly 14 to transmit the actuating force to the first and second drive rods 20a, 20b with an actuation. The guide pins 18a, 18b are each formed as eccentric bearing pins 22 having an eccentrically disposed pivot axis 24 for rotatable attachment to the slidable facade component. The guide pins 18a, 18b are provided for engagement with a guide groove arrangement 26 arranged in the frame area (see
The guide groove 27 is provided, for example, on the side of the post frame.
The eccentric bearing pin 22 is supported on one side of the guide groove. This area forms an inner stop to push the sash outward against a stop.
The horizontal offset can be approx. 6 mm, for example.
Optionally shown in
As a further option,
As another option, but not shown, it is provided that the slidable component is a horizontally slidable component. The first side is a horizontally extending lower side of the slidable component, and the second side of the slidable component is a horizontally extending upper side of the slidable component. The first guide groove and the second guide groove extend horizontally.
The slidable facade component serves to openably close an opening in the building envelope and, in addition to being designed as a window with a translucent, e.g. transparent or translucent filling, can also be designed as an opaque surface, for example.
The slidable facade component, in particular the frame profiles, and the adjacent fixed frame structure can be made of materials such as wood materials, plastics and metal materials, and composite materials. In other examples, a combination of these materials is provided.

Another sealing 37 is provided at the top edge, which abuts the other wing.
As an option, a sealing arrangement is provided at least in a partial area between the slidable component and the fixed edge of the opening. Pressing the slidable component against the fixed frame area causes the opening to be sealed. For example, the sealing arrangement comprises elastic seals which are at least partially compressed by the pressing action.
In an option, a sealing arrangement is formed along at least the first side and the second side of the slidable component to form a sealing plane with the fixed opening edge that is parallel to the plane of the slidable component.

Optionally, the coupling member 28 is shown to include a lever 42 projecting from the eccentric bearing pin 22 and having a slot 44 for engagement with a pin 46 attached to the drive rod 20a. A longitudinal hole 45 indicates the range of motion of the pin 46.
When the window is operated to close, for example, the drive rod 20a is moved via a handle element. This also moves the bolt 46. From
In
In the upper part,
A lateral sealing 62 is held in a groove 64 on the lateral sash profile 58. A sealing stop 66 for the lateral sealing 62 is formed on the fixed opening edge 52. As a further option, a lateral wind driven rain sealing 68 can also be provided. The lateral sealing 62 can also be referred to as part of a main sealing.
The sealing stop 66 on the frame can extend outwardly at an angle at the upper portion of the sash to provide a transition of the sealing to the upper sash there.
The sealing can also be attached in reverse, i.e. to the fixed frame instead of to the slidable component.
In the middle section,
In the lower portion, a vertical section of a lower sash profile 70 of the lower sash 32 is shown in
A lower sealing 74 is held in a groove 76 on the lower sash profile 70. On the lower profile segment 72, a profile surface serves as a stop 78 for the lower sealing 74. The lower sealing 74 can also be referred to as part of a main sealing.

In the first handle position G1, the sash can be moved, for example by lifting or lowering it at the handle 80 itself. In the second handle position G2, the sash is increasingly pressed against the sealing in a direction transverse to the sliding direction. In the third handle position G3, the sash is pressed against the sealing transverse to the sliding direction so that a reliable sealing is provided.
In an example not shown in further detail, the actuation has a counter-rotating gear. With the counter-rotating gear, the first drive rod and the second drive rod can be moved in the same direction in relation to the movable component during actuation.
In
In
This is shown, for example, in
For example, a lowering of approx. 2 mm can take place so that the sealing is in contact, and a further lowering of approx. 1 mm so that the sealing is compressed.
In the first grip position G1, there is still no contact between the radially projecting projection 82 and the stop element 84. In the second grip position G2, abutting then occurs. In the third grip position G3, the sash is then pressed down so that a reliable sealing is also provided in the lower area.
If a gearbox without counter-rotation deflection is used for the operation, the rotation of the window handle moves the push rod in the same direction on all sides of the frame; either to the right or to the left, or clockwise or counter-clockwise. To enable locking even with this hardware configuration, an eccentric plate with a locking disc is mounted, for example, next to the lowest sliding bolt mounted on the side of the push rod. This locking disk can provide locking of the sash to the post frame during both upward and downward movement of the push rod. By turning the locking disc to the right or to the left, the locking disc mounted on the sliding sash engages around a locking bolt fixedly mounted on the post frame. The sliding sash can only be moved again after the connection has been released.
Optionally, at least one of the eccentric bearing pins is formed with a locking mechanism 100. For this purpose, for example, a locking disc 102 is provided having a receptacle 104 for engagement with a locking pin 106 provided on a stationary frame portion.
In
For example, a drive pin 111 is provided on a drive rod to rotate the locking disc 102.
For example, the sash is lowered from above. The locking disc 102, which is rotatably mounted on the sash, is moved from above toward the locking bolt 106, which is attached to a side fixed frame member. For example, the locking bolt 106 is attached to a plate 112. In an embodiment, the locking bolt 106 is attached directly to the frame without the plate 112. The locking bolt 106 dips into the inlet slot 108. By rotating the locking plate 102, for example via one of the driving rods that is present anyway, the edge segment 110 can be rotated in front of the locking bolt 106. The term “forward” as used herein refers to the relative path of movement that the sash can move in relation to the locking pin 106.
In an option, it is provided that at least one eccentric bearing pin is provided on each of the first and second sides with the locking disc with the inlet slot. The entry slot with the edge segment is formed on the first side as a mirror image of the entry slot with the edge segment on the second side. With the actuation, the first drive rod and the second drive rod can be moved in opposite directions with respect to the slidable component.
By forming the contour of the inlet slot 108 in a mirrored manner, the rotation of the locking disk 102 can also be “mirrored”. For example, if the drive rod is driven by a gear in only one direction, a downward movement of the drive pin 111 occurs on one side, e.g., the left side, and an upward movement occurs on the other side, e.g., the right side.
On the left side, downward movement of the drive pin 111 causes the locking disk 102 to rotate counterclockwise.
On the right side, movement of the drive pin 111 upward causes clockwise rotation of the locking disk 102.
However, in both cases, the mirrored contour of the locking disc allows positive locking to be achieved by engaging behind the locking pin 106.
In another option, it is provided that the locking discs are formed identically on both sides and with the actuation, e.g. a handle and a gear, the first driving rod and the second driving rod can be moved in the same directions with respect to the slidable component.
In
This also allows, for example, additional locking pins 106 to be arranged at intermediate positions over which the locking disc 102 can be moved when in the appropriate rotational position.
In an example, locking discs open on both sides (top and bottom) are provided. A locking disk open on both sides can also be designed, for example, several times one above the other.
During the upward or downward movement of the slidable sash, the locking bolt, which is permanently mounted on the post frame, is passed through the locking disk, for example. The locking bolt can be mounted e.g. several times on top of each other on the post frame.
In a variation, oval locking bolts are provided. The use of oval locking bolts combined with open locking disc can e.g. fix the sash in different positions (use for e.g. gap ventilation). The oval locking bolt can be combined with round locking bolts, for example.

The locking solutions shown in
In an example, the locking solutions shown are operated with a co-rotating standard gear unit. In case of the co-rotating standard gear unit, the bolts permanently mounted on the drive rods move in the same direction, for example—in relation to the window sash - clockwise or counterclockwise. The movement is synchronous, for example
In another example, the locking solutions shown are operated with a counter-rotating gear. In case of the counter-rotating gear unit, the bolts permanently mounted on the drive rods move in a mirrored direction of movement with respect to the two sides (top/bottom or right/left), for example upwards or downwards in case of a lateral arrangement, or to the right or left in case of an arrangement at the top and bottom. The movement is synchronous, for example.

In a first step 302, also referred to as step a), a slidable component is guided in a guide groove arrangement by engaging guide pins formed as eccentric bearing pins. The slidable component is configured for openably closing a facade opening formed by a fixed opening edge. At least two guide pins are provided for a first side of the slidable component and at least two guide pins are provided for a second side of the slidable component opposite the first side. The guide groove arrangement has a first guide groove in a first edge region of the opening edge and a second guide groove in a second edge region of the opening edge opposite the first edge region. The eccentric bearing pins are each rotatably mounted on the slidable component with an eccentrically arranged axis of rotation and are in engagement with one of the guide grooves.
In a second step 304, also referred to as step b), an actuating device coupled to drive rods is actuated. Actuation of the actuating device causes longitudinal movement of the drive rods. The eccentric bearing pins are coupled to the drive rods via coupling elements, and the longitudinal movement of the drive rods causes the eccentric bearing pins to rotate.
In a third step 306, also referred to as step c), the eccentric bearing pin is rotated within the guide groove by actuation of the actuator.
In a fourth step 308, also referred to as step d), the slidable component is pressed against a stationary frame region transverse to the guiding direction and the slidable component is moved transverse to the guiding direction.
The guiding, actuating, turning, pressing as well as moving all take place almost simultaneously, in an example.
The coupling element 122 is formed as a releasable connection between the eccentric bearing pin 124 and the drive rod (not shown). The coupling element 122 can be coupled to a pin attached to the drive rod (see reference numeral 46 in
Optionally, coupling member 122 and eccentric bearing pin 124 are shown to be integrally formed. The adapter attachment 120 includes a first region 126 having a circular outer contour 128. The adapter attachment 120 also includes a second region 130 having a slot 132 for insertion of a free end of a bolt. The adapter attachment 120 includes a hole 134 eccentric to the round outer contour 128 for rotatably attaching the adapter attachment 120 to a frame segment of the slidable facade component.
The adapter attachment 120 is made of plastic, for example.
The coupling element 122 and the eccentric bearing pin 124 form a gear for converting a longitudinal movement of a drive rod extending parallel to the plane of the movable facade component into a movement of the movable facade component directed transversely to the plane of the movable facade component.

In the example, two of the parallel outer linear longitudinal edges 144 are shown.
Spring regions 146 are formed on at least one side of the parallel outer linear longitudinal edges 144, which resiliently project beyond an abutment region 148 of the longitudinal edges 144 in the direction of the cross-section of the guide groove assembly. The spring regions protrude in the longitudinal direction of the guide groove assembly.
Optionally, it is provided that a spring force of the spring sections can be adjusted to set a contact pressure of the lateral cantilevers for generating a braking effect.
