The invention relates to a fitting arrangement for connecting a slidable and tiltable leaf to a fixed frame of a window or a door, wherein the fitting arrangement has a scissor type deployment means having a deployment arm and a control arm which is movably arranged on the deployment arm, wherein the scissor type deployment means has a control pin and the fitting arrangement further has a control element having a fixing portion which can be fixed to the fixed frame and an introduction portion having a slotted introduction member for receiving the control pin. The invention further relates to a window or door having such a fitting arrangement.
It is known to provide windows, doors or the like with a slidable leaf. In order to open the leaf, the leaf is released from a closure position, in which it abuts the fixed frame, in a pivot movement from the fixed frame and then displaced parallel with the main plane of the fixed frame. In this case, the leaf is connected to the fixed frame via at least one scissor type deployment means of a fitting arrangement. In the released position of the leaf, the scissor type deployment means is engaged in a release position. The leaf is thereby prevented from pivoting back during displacement of the leaf. Such a displaceable leaf has become known from EP 1 959 080 A2.
During closure of the leaf, a control pin strikes a control element which is described in the introduction. Such a control element is also known by the term “control block”. The control element is mounted on the fixed frame directly or indirectly, for example, indirectly via a mounting rail. The control pin is introduced into the slotted introduction member of the control element, whereby the engagement of the scissor type deployment means is cancelled and the leaf can be pivoted inwards again.
EP 2 824 264 A1 disclosed a fitting arrangement for a window or a door, by means of which a leaf can be both released parallel from a fixed frame and tilted. However, the known control element of EP 2 824 264 A1 is constructed with a relatively big depth in the main frame plane of the fixed frame or parallel with this main frame plane of the fixed frame.
Therefore, an object of the invention is to provide a fitting arrangement which allows both displacement and tilting of a leaf of a window or door in a small structural space. Another object of the invention is to provide a window or a door having such a fitting arrangement.
The object according to the invention is achieved by a fitting arrangement according to patent claim 1 and a window or a door according to patent claim 15. The dependent claims set out preferred developments.
Consequently, the object according to the invention is achieved by a fitting arrangement for connecting a slidable and tiltable leaf to a fixed frame of a window or a door. The fitting arrangement has a scissor type deployment means having a deployment arm and a control arm. The scissor type deployment means, in particular the control arm, has a control pin. The fitting arrangement further has a control element. The control element has a fixing portion which can be fixed in a non-movable manner to the fixed frame of the window or door.
The control element further has an introduction portion which can be moved relative to the fixing portion. More specifically, the introduction portion is arranged so as to be movable relative to the fixing portion between an introduction position and a tilted position. The introduction portion has a slotted introduction member for receiving the control pin. In the introduction position, the control pin can be introduced and withdrawn into/from a slotted introduction member of the introduction portion while it cannot be introduced and withdrawn into/from the slotted introduction member in the tilted position but instead is retained by the fixing portion in the slotted introduction member. According to the invention the introduction portion now directly adjoins in the introduction position itself the fixing portion partially in a positive-locking manner (form fit/form lock). If the control pin in this introduction position is introduced into the slotted introduction member, the impact of the control pin is discharged via the positive-locking connection of the introduction portion with respect to the fixing portion into the fixing portion and finally into the fixed frame. The impact does not result in the introduction portion being moved into the tilted position. Instead, the introduction portion can be moved into the tilted position by the control pin only when the scissor type deployment means moves the introduction portion out of the positive-locking connection with respect to the fixing portion.
Consequently, according to the invention there is provided a fitting arrangement which, on the one hand, allows a linear tilting movement of a leaf which is mounted on the fitting arrangement by the movement of the introduction portion into the fixing portion and, on the other hand, allows a reliable stop for the control pin during closure of a leaf from the released position thereof by the partial positive-locking connection of the introduction portion with respect to the fixing portion in the introduction position.
A corner region of the introduction portion preferably forms the partial positive-locking connection of the introduction portion with respect to the fixing portion in the introduction position.
The fixing portion may have an introduction recess in which the introduction portion in the introduction position abuts in a partially positive-locking manner. In this case, the scissor type deployment means is constructed to move the introduction portion out of the introduction recess during opening of the scissor type deployment means so that the introduction portion can be moved by the control pin into the tilted position during further opening of the scissor type deployment means.
The movement of the introduction portion out of the partial positive-locking connection is preferably carried out by a pivoting movement of the introduction portion. The further movement of the introduction portion into the tilted position is preferably carried out in the fixing portion by a linear sliding movement of the introduction portion.
The pivoting of the introduction portion out of the introduction position can be carried out about the axis of a fixing pin which is arranged at one end on the introduction portion and which is guided at the other end in a slotted fixing member.
The pivoting of the introduction portion out of the introduction position is preferably carried out about the axis of the control pin or parallel with the axis of the control pin. The fitting arrangement can thereby be constructed in a structurally particularly simple manner.
In another preferred embodiment of the invention, the introduction portion is moved by the control arm out of the introduction position during opening of the scissor type deployment means.
In order to prevent the introduction portion from already being moved out of the partial positive-locking connection with respect to the fixing portion when the scissor type deployment means is closed and the occurrence of jamming of the scissor type deployment means when the leaf is closed, the control element preferably has a free-running member which is constructed in such a manner that the introduction portion is moved out of the partial positive-locking connection with respect to the fixing portion only when the scissor type deployment means is opened.
The free-running member may have a free-running pin which is acted on by a free-running spring of the free-running member with a resilient force, wherein the scissor type deployment means is constructed in such a manner that the free-running pin is redirected during closure of the scissor type deployment means and no movement of the introduction portion out of the partial positive-locking connection with respect to the fixing portion is thereby carried out, wherein no redirection or only a negligible redirection of the free-running pin counter to the resilient force of the free-running spring is carried out when the scissor type deployment means is opened so that the scissor type deployment means moves the free-running pin together with the introduction portion out of the partial positive-locking connection of the introduction portion with respect to the fixing portion.
The control arm is preferably arranged at one end in a pivotable manner on the deployment arm and, at the other end, is constructed in a sawtooth-like manner, wherein the gradient of a first flank of the sawtooth displaces the free-running pin and a second flank of the sawtooth is constructed to be so steep relative to the free-running pin that the control arm does not displace the free-running pin. The second flank may be constructed in a semi-circular manner.
In another embodiment of the invention, the control element may have a reversibly releasable engagement device on the introduction portion in order to allow a reversibly releasable engagement connection in the tilted position of the introduction portion with respect to the fixing portion. This prevents the leaf from slamming shut in the tilted position as a result of a gust of wind. Alternatively or additionally, the engagement device can press the introduction portion in the introduction position into the partial positive-locking connection with respect to the fixing portion. The introduction portion is thereby reliably retained in the introduction position at least partially in a positive-locking manner with respect to the fixing portion so that an impact which is brought about by the control pin which is introduced into the slotted introduction member is discharged reliably into the fixing portion or further into the fixed frame.
In this case, the engagement device may have an engagement spring and an engagement element which is acted on with a resilient force by the engagement spring. The engagement element is preferably constructed in the form of a ball for simplified construction of the fitting arrangement.
A reliable discharge of the impact produced by the control pin into the fixing portion or further into the fixed frame is brought about if the fixing portion has a stop face for the control pin which merges into a side wall of the slotted introduction member in the introduction portion.
In a further preferable manner, the control element has a slotted guiding member so that the introduction portion can be moved relative to the fixing portion but is arranged in a non-releasable manner on the fixing portion.
The control pin may have an end-side head portion with an expanded cross-section. In other words, the control pin may be constructed in a substantially mushroom-like manner so that it can be guided in a particularly reliable manner by rear engagement which is brought about at least partially in the control element.
The scissor type deployment means may be able to be mounted at one end directly on the leaf. The fitting arrangement preferably has at one end of the scissor type deployment means a leaf rail which can be mounted on the leaf. The fitting arrangement preferably has at the other end of the scissor type deployment means a slider of the fitting arrangement, which slider is movable, preferably slidable, directly or indirectly on the fixed frame. The slider may be constructed in the form of a slider rail. The leaf rail and slider rail may be connected to each other via another deployment arm in addition to the scissor type deployment means.
In order to guide the opening and closing movement of the scissor type deployment means, the control arm may have a control arm slotted guiding member, in which a control arm guide bolt, in particular of the slider, engages. As set out in the introduction, the scissor type deployment means is engaged in the release position, that is to say, in the released position of the leaf. The control arm slotted guiding member preferably has at one end an engagement indentation in which the control arm guide bolt engages in this open position of the scissor type deployment means. The movement of the control pin into the slotted introduction member is used in this case to guide the control arm guide bolt out of the engagement indentation.
The fitting arrangement according to the invention can preferably be controlled only by a movement of the leaf but not by a push rod. In other words, the fitting arrangement is not in this case a force-controlled fitting arrangement but instead only passively affords the movement possibility for the leaf which is moved by a user.
The object according to the invention is finally achieved by a window or a door having an above-described fitting arrangement, wherein the fitting arrangement connects a fixed frame of the window or door to a tiltable and slidable leaf of the window or door and the fixing portion is mounted in a non-movable manner relative to the fixed frame.
Other features and advantages of the invention will be appreciated from the following detailed description of an embodiment of the invention, with reference to the Figures of the drawings which show the inventively significant details, and from the patent claims.
The features illustrated in the drawings are depicted in such a manner that the particular features according to the invention can be made clearly visible. The different features may be implemented individually per se or together in any combinations in variants of the invention.
The fitting arrangement 24 according to the invention (see
The fitting arrangement 24 has a mounting rail 32 which is mounted securely on the fixed frame 12. The slider 30 is movable in the longitudinal direction of the mounting rail 32 in order to be able to displace the leaf 14 (see
In order to close the window 10 (see
In order to move the control arm guide bolt 34 out of the engagement indentation 36, the control arm 40 is pivoted. The pivoting is brought about by a control pin 44 which is guided by a control element 46.
In order to retain the introduction portion 54 in a non-releasable manner relative to the fixing portion 52, the mounting plate 56 has a slotted guiding member having a slotted fixing member 58, in which at one end a fixing pin 60 which is arranged at the other end on the introduction portion 54 is guided.
A free-running pin 62 which can be displaced relative to the introduction portion 54 and which is acted on with the resilient force of a free-running spring 64 is arranged on the introduction portion 54. Furthermore, an engagement element 66 which is acted on with the resilient force of an engagement spring 68 is arranged on the introduction portion 54. The introduction portion 54 further has a slotted introduction member 70 for receiving the control pin 44.
If the leaf 14 (see
During the movement of the fitting arrangement 24 into a tilted position, the control pin 44 must be displaceable substantially along the longitudinal axis 78 of the fixing element 52 in order to allow the upper-side outward tilting of the leaf 14 (see
The introduction portion 54 consequently has two degrees of freedom: in a first degree of freedom, the introduction portion 54 can be displaced substantially along the longitudinal axis 78 or substantially parallel with the longitudinal axis 78. In a second degree of freedom, the introduction portion 54 can be pivoted from the position thereof, in which the longitudinal axis thereof extends in the longitudinal axis 78 or parallel with the longitudinal axis 78, into the introduction position, in which an outer edge of the introduction portion 54 abuts the straight abutment member 98.
In the tilted position shown according to
Taking all the Figures of the drawings together, the invention relates in summary to a fitting arrangement 24 for a window 10 or a door having a leaf 14 which can be both tilted and released from the fixed frame of the window 10 or door and displaced parallel with the fixed frame 12. The fitting arrangement 24 has a control element 46 with a fixing portion 52 which can be fixedly mounted on the fixed frame 12 indirectly and/or directly. The control element 46 has an introduction portion 54 which may be pivotable and displaceable relative to the fixing portion 52. In an introduction position, in which a control pin 44 of the fitting arrangement 24 can be introduced into the introduction portion 54, an end portion of the introduction portion 54 abuts, preferably at least partially, the fixing portion 52 so that an impact of the control pin 44 on the introduction portion 54 is discharged into the fixing portion 52 via the end portion which abuts the fixing portion 52. The introduction portion 54 is preferably pivotable out of the positive-locking connection with respect to the fixing portion 52, preferably by a control arm 40 of the fitting arrangement 24, on which in particular the control pin 44 is also arranged or constructed, so that the introduction portion 54 can subsequently be displaced by the control pin 44. The control element 46 may have a free-running member 82 by which the outward pivoting of the introduction portion 54 is brought about only when the fitting arrangement 24 is opened but not when the fitting arrangement 24 is closed.
