Definitions

  • the invention relates to a fitting arrangement for the sash of a window, a door or the like, in particular for a sash that can be opened in a tilt and turn manner.
  • Such a fitting arrangement can mount the sash movably on a frame of the window or door.
  • the fitting arrangement is attached to the sash and corresponding counterparts are attached to the frame on the so-called hinge side of the window or door, on which the fitting arrangement can then be mounted movably, in particular pivotally, by means of a bearing band.
  • the fitting arrangement can, for example, comprise an elongated swivel arm, which is attached to the wing and is connected at its hinge-side end via the bearing band to a swivel bearing to be provided on the frame, for example by hooking the bearing band onto the swivel bearing, so that the swivel arm and with it the Wings are held by the pivot bearing, but at the same time can be moved, in particular pivoted about an axis of rotation defined by the pivot bearing.
  • a particularly suitable bearing band is a so-called band angle, which can be angled one or more times in order to achieve a certain offset between the swivel arm and the swivel bearing.
  • a so-called scissor arm is used as a swivel arm for a sash that is intended to be both rotary and tilt-openable, which allows the side of the sash on which it is provided to be aligned exclusively radially to the respective bearing to be displayed parallel, so that the sash is thereby tilted on its opposite side.
  • the swivel arm mentioned can also be designed as a pure rotating hinge arm or purely tilting hinge arm (or rotating or tilting hinge forend) or enable other kinematics of the sash relative to the frame.
  • a corresponding variability as with the swivel arms is not necessary for the swivel bearings, especially for the so-called scissor bearings, which are typically provided at the top of the respective hinge side of the sash. As a rule, they only have to enable the respective swivel arm to be pivoted and are therefore essentially independent of the shape of the wing and the way it can be opened.
  • the bearing band via which a swivel arm is mounted on a swivel bearing, can therefore be designed in the same way for different swivel arms. For this reason, it is advisable to manufacture the bearing bands not as an integral part of the swivel arms, but as separate parts, which are then each firmly connected to a swivel arm. In this way, different swivel arms can be produced, but each have the same bearing band.
  • a respective pivot arm is not determined from the outset as to where the hinge side of the wing is, i.e. around which of its sides the wing can be pivoted.
  • a respective swivel arm can in principle be used on both left-hand and right-hand opening sashes. Only by coupling it to a bearing belt is the swivel arm then fixed to a specific side of the belt. This determination can result from the choice of the bearing band and/or the type of arrangement of the bearing band on the swivel arm. In the latter case, the fitting arrangement can also be changed by changing the alignment of the bearing band on the swivel arm be reconfigurable. This means that the fitting arrangement can be used particularly flexibly.
  • the swivel arm and the bearing band are designed separately, it is important that these parts are reliably coupled to one another at the latest when the fitting arrangement is installed on a respective sash. Particularly in the swung-open state, the wing is largely supported by the frame via this coupling.
  • the swivel arm typically extends radially to the axis of rotation and is therefore attached to one of the sides of the wing that are aligned perpendicular to the hinge side.
  • the bearing band on the other hand, is usually arranged on the band side of the wing for interaction with the pivot bearing. It is therefore expedient if the swivel arm has a carrying handle at its belt-side end, which includes a leg that is angled relative to the rest of the swivel arm and which can be used for coupling to the bearing belt.
  • the bearing band can simply be screwed or riveted to the angled leg of the carrying handle.
  • a type of coupling requires the use of tools and therefore means additional effort when assembling the fitting arrangement.
  • a rivet connection is also irreversible, meaning that the fitting arrangement can no longer be reconfigured if the wrong pivot arm is selected or the wrong hinge side is set.
  • a type of connection that is easy to close, yet reliable and can also be detached again can be achieved using a bayonet lock.
  • a bayonet lock For this purpose, it can be provided in particular that there is a bayonet receptacle on the carrying handle of the swivel arm and on a coupling section of the bearing band a bayonet bolt is provided. The carrying handle and the bearing band can be inserted into one another and fastened to one another by turning the bayonet bolt in the bayonet receptacle.
  • a fitting arrangement according to the preamble of claim 1 is, for example DE 40 40 233 A1 known. Further, fundamentally similar fitting arrangements are presented in DE 19 23 282 U , DE 41 09 636 A1 , DE 30 24 746 A1 and DE 20 2004 019551 U1 described.
  • the fitting arrangement according to the invention for the sash of a window, a door or the like comprises a swivel arm which is designed to be attached to the sash and which has a carrying handle with a leg angled transversely to the longitudinal extent at a hinge-side end of its longitudinal extent.
  • the wing can in particular be a turn-tilt-openable sash.
  • the swivel arm can be designed in particular as a scissor arm.
  • the swivel arm in particular has an elongated shape which extends between said band-side end and an opposite, band-remote end. The two ends define a longitudinal axis of the swivel arm, along which the said longitudinal extent is defined.
  • the carrying handle with the leg that is angled relative to the rest of the longitudinal extent of the swivel arm can in principle be designed as a structural unit with the swivel arm.
  • the carrying handle can correspond to a section of the swivel arm and can essentially be formed in that the swivel arm is bent over at its band-side end, so that the bent part forms the said leg.
  • the carrying handle is a component manufactured separately from the swivel arm, which is firmly connected to the swivel arm, for example riveted.
  • the carrying handle can essentially be designed as an angle with two legs, one of which forms the aforementioned angled leg. The further leg of the carrying handle then serves to attach the carrying handle to the swivel arm and is expediently aligned parallel to the longitudinal extent of the swivel arm.
  • the swivel arm is preferably designed to be fastened in the rebate on one side of the sash, in particular on its top side.
  • the carrying handle can then be arranged at a corner of the wing and encompass it, in particular in such a way that said angled leg is at least essentially vertically aligned.
  • the fitting arrangement further comprises a bearing band which is designed to be pivotably mounted with a bearing section on a pivot bearing to be provided on the frame of the window or door about an axis of rotation of the pivot bearing to be, and which has a coupling section which can be coupled to the angled leg of the carrying handle of the swivel arm by means of a bayonet lock.
  • the bearing section mentioned can, for example, be designed as a sleeve into which a bearing pin of the frame-side pivot bearing can engage, so that the bearing band can be rotated about the bearing pin.
  • the mentioned coupling section of the bearing band can, for example, have at least essentially a plate shape.
  • the bearing band can in particular be designed as a so-called band angle.
  • the bearing band can be angled (even multiple times) in such a way that the plane defined by the plate shape of the coupling section deviates from a radial orientation to the axis of rotation, for example by an angle of at least 30° and/or at most 60°, in particular approximately 45°.
  • the pivot bearing can in particular be a so-called scissor bearing.
  • the bayonet lock comprises a bayonet bolt extending along a bolt axis and a bayonet receptacle, which are designed in such a way that, in order to close the bayonet lock, the bayonet bolt is inserted axially into the bayonet receptacle with respect to the bolt axis and is then rotated relative to the bayonet receptacle about the bolt axis into a coupling position, in the form-fitting means of the bayonet bolt engage behind the form-fitting means of the bayonet receptacle and thereby lock the bayonet pin against axial exit (with respect to the bolt axis) from the bayonet receptacle.
  • the said stretching is a pure translational movement, i.e. is not superimposed by any rotation.
  • the subsequent rotation into the coupling position can also be superimposed by movement components in the axial direction, for example in the manner of a screwing movement and/or for overcoming a locking edge.
  • the bayonet pin After the bayonet pin is inserted into the bayonet receptacle, but before it is then rotated relative to the bayonet receptacle, the bayonet pin is in a release position in which the positive locking means of the bayonet pin do not engage behind the corresponding positive locking means of the bayonet receptacle and the bayonet pin is therefore again axially out of the Bayonet mount can come out.
  • the bayonet bolt back from the coupling position to the release position the positive connection can therefore be canceled again and the bayonet lock can thus be released again.
  • the bayonet bolt and the bayonet receptacle are designed in particular in such a way that, in order to close the bayonet lock, the bayonet bolt is inserted axially into the bayonet receptacle with respect to the bolt axis and is then rotated relative to the bayonet receptacle about the bolt axis from a release position into a coupling position, in the coupling position Positive locking means of the bayonet bolt engage behind corresponding positive locking means of the bayonet receptacle and thereby lock the bayonet bolt against axial exit from the bayonet receptacle, but not in the release position;
  • the bayonet bolt and the bayonet receptacle can advantageously also be designed in such a way that, in order to open the bayonet lock, the bayonet bolt is rotated relative to the bayonet receptacle about the bolt axis from the coupling position into the release position and is then removed axially from the bayonet recepta
  • the bayonet bolt is preferably arranged on the bearing band, with the bayonet receptacle then being provided on the carrying handle.
  • the bayonet pin can also be arranged on the carrying handle in the opposite way; In this case, the bayonet mount is then provided on the bearing band.
  • the positive locking means can each be formed in particular by radial projections with respect to the bolt axis, for example bayonet wings, and/or radial depressions, for example undercuts, grooves or link guides.
  • the bayonet bolt can have one or more such projections, preferably at least two bayonet wings, and the bayonet receptacle can have one or more such recesses, preferably at least two undercuts.
  • the bayonet receptacle can also have one or more radial projections and/or the bayonet bolt can have one or more radial recesses.
  • a securing spring with a locking tongue is provided on the bayonet receptacle, which is arranged in such a way that when the bayonet bolt is axially inserted into the bayonet receptacle, it is acted upon by the bayonet bolt and is deflected axially into a deflection position with respect to the bolt axis against a restoring force of the securing spring and by this Turning the bayonet pin into the coupling position is released for returning to a locking position, into which it is moved due to the restoring force of the securing spring and in which it locks the bayonet pin, in particular in a form-fitting manner, against rotation out of the coupling position.
  • the locking tongue can in particular be designed integrally with the securing spring.
  • the locking tongue it is also possible for the locking tongue to be designed separately and to be attached to the securing spring, preferably to a free end of the securing spring.
  • the securing spring can in particular be provided on the bayonet receptacle in that it is attached to the component (bearing band or carrying bracket) on which the bayonet receptacle is provided and is adjacent to the bayonet receptacle, overlaps with it when viewed in a direction parallel to the bolt axis and/or each other extends into the bayonet mount.
  • the locking tongue of the safety spring automatically engages when the bayonet lock is closed by inserting the bayonet bolt into the bayonet receptacle and rotating the bayonet bolt relative to the bayonet receptacle.
  • the insertion causes the deflection and thus tensioning of the safety spring with the locking tongue.
  • the rotation then enables the locking tongue to be axially reset to its locking position due to the pretension of the safety spring and thereby to snap into place on the bayonet pin.
  • the locked state i.e. when the bayonet pin inserted into the bayonet receptacle is in the coupling position and the locking tongue assumes its locking position, the bayonet pin is secured against leaving the coupling position.
  • the latching is preferably such that it is accompanied by acoustic feedback.
  • the latching can preferably be heard clearly, for example as a click or clack.
  • a fitter of the fitting arrangement advantageously receives clear feedback as to whether the bayonet lock is closed reliably, namely secured by the locking tongue, or not. This contributes to safe use of the fitting arrangement.
  • the securing of the bayonet bolt must first be released again by the locking tongue in order to unlock the bayonet bolt and enable it to be rotated out of the coupling position.
  • the securing spring when the locking tongue assumes its locking position, the securing spring is not completely relaxed, but continues to exert a pre-tension in the direction the stated restoring force.
  • the locking tongue is biased in its locking position in the direction away from the deflection position. This makes it very unlikely that a vibration is capable of moving the locking tongue so far out of the locking position that the bayonet pin is released, let alone moving the bayonet pin simultaneously from the coupling position to the release position. This means that automatic opening of the bayonet lock is almost impossible.
  • the locking tongue of the safety spring is arranged such that it engages in the bayonet receptacle in the locked position.
  • the locking tongue can interact particularly easily with the bayonet bolt inserted into the bayonet receptacle in order to lock it.
  • the locking tongue can block a path that a part of the bayonet bolt, in particular the positive locking means of the bayonet bolt, would travel when rotating out of the coupling position.
  • the locking tongue can preferably be supported radially outwards on the bayonet receptacle with respect to the bolt axis and thereby lock the bayonet pin particularly reliably.
  • the locking tongue of the securing spring is arranged such that it engages in the bayonet receptacle, at least as long as the bayonet bolt is not inserted into the bayonet receptacle.
  • the locking tongue can, so to speak, be in the way of the bayonet pin when it is inserted into the bayonet receptacle and can therefore be acted upon axially by the bayonet pin in a simple manner.
  • the bayonet bolt has at least one (relative to the bolt axis) radially projecting bayonet wing as a positive locking means, whereby when the bayonet bolt is inserted into the bayonet receptacle and rotated into the coupling position, the locking tongue of the securing spring in its locking position in the circumferential direction (with respect to the bolt axis) rests against the bayonet wing and thereby blocks the bayonet bolt against rotation out of the coupling position, preferably in a form-fitting manner.
  • the locking tongue is preferably designed to be complementary to the bayonet wing in such a way that it rests on the bayonet wing not only at points, but at least along a contact line, preferably along a contact surface.
  • the locking tongue in the locking position both rests on the bayonet wing and engages in the bayonet receptacle and is supported on the bayonet receptacle radially outwards with respect to the bolt axis. This can ensure that the locking tongue is clamped between the bayonet wing and the bayonet receptacle when the bayonet pin is forced to rotate out of the coupling position, whereby the bayonet pin is blocked particularly reliably against such a rotation.
  • the bayonet bolt when it is inserted into the bayonet receptacle, acts on the locking tongue of the securing spring with a bayonet wing that projects radially (with respect to the bolt axis), in particular with the bayonet wing mentioned above, and deflects it into the deflection position.
  • the bayonet wing therefore not only serves to couple the bayonet pin with the bayonet receptacle by reaching behind the corresponding form-fitting means of the bayonet receptacle, but can also serve to push back the locking tongue when the bayonet pin is inserted into the bayonet receptacle and then turn away from under the locking tongue so that it is behind can spring back into place on the bayonet wing.
  • the securing spring is designed as a leaf spring, which is attached to the carrying handle or the bearing band with a fastening section and has a spring arm which is elongated Structure extends away from the fastening section, the locking tongue being formed by an end section of the spring arm.
  • a leaf spring has the particular advantage that it takes up comparatively little space. Said spring arm can extend between a fixed end adjacent to the fastening section and a free end, said end section then preferably being formed at the free end.
  • the locking tongue is formed by said end section of the spring arm, and is therefore an integral part of the spring arm and thus of the securing spring.
  • the spring arm can, for example, be designed as a substantially flat strip.
  • the locking tongue can then be formed by a single or multiple bent end section of the strip and thereby protrude at least partially, in particular vertically, from the remaining spring arm.
  • the locking tongue can also lie in the same plane as the rest of the spring arm.

  • an embodiment may also be advantageous in which at least said fastening section of the securing spring is inserted into a receiving recess formed on the carrying bracket or the bearing band, which has a shape that is complementary to the shape of at least the fastening section of the securing spring.
  • This complementary design means that the leaf spring, which is inserted into the receiving recess at least with its fastening section, is particularly well secured against slipping.
  • the leaf spring is also attached in such a way that it cannot be removed from the receiving recess.

  • the locking tongue 43 of the locking spring 13 is acted upon by one of the bayonet wings of the bayonet bolt 29 and in the direction of insertion, i.e. axially with respect to the bolt axis B, into an in Fig. 3b or 6b shown deflected.
  • the deflection takes place against a restoring force of the securing spring 31, which increases with increasing deflection.
  • the securing spring 31 In the deflection position, the securing spring 31 therefore presses axially with its locking tongue 43 against the bayonet bolt 29, which, however, does not prevent it from coming out of the in Fig. 3a or 6a shown release position via the in Fig. 3b or 6b shown intermediate position into the in Fig. 3c or 6c shown coupling position to be rotated.
  • the bayonet wing through which the locking tongue 43 was deflected rotates away under the locking tongue 43.
  • the locking tongue 43 When the bayonet bolt 29 has reached its coupling position, the restoring force of the securing spring 13 causes it to return axially into the in Fig. 3c or 6c shown safety position offset and locks behind the bayonet wing.
  • the locking tongue 43 engages in the bayonet receptacle 31 and rests laterally on the bayonet wing that previously acted upon it.
  • the locking tongue 43 is located in the movement path of the bayonet wing, which it would have to cover in order to turn the bayonet bolt 29 back into the release position.
  • the bayonet bolt 29 is positively locked by the safety spring 13 against turning back from the coupling position into the release position.
  • the locking tongue is supported radially outwards against the bayonet receptacle 31, so that it cannot be pushed out of the way by the bayonet bolt 29. To prevent further rotation in the other direction, i.e.
  • the bayonet bolt 29 is also blocked by a locking contour 45 formed on the bayonet receptacle 31. Consequently, the bayonet lock 27 is reliably secured in its closed state by the securing spring 13, in particular against automatic loosening, for example due to vibrations.
  • the movement sequence for an intended opening of the bayonet lock 27 corresponds to a reversal of the process for closing the bayonet lock 27.
  • the locking tongue 43 must be moved manually into the deflection position when opening before the Bayonet bolt 29 can be rotated back into the release position and then removed axially from the bayonet receptacle 31.
  • the securing spring 13 is designed as a leaf spring.
  • the leaf spring has a fastening section 47, with which it is attached to the leg 19 of the carrying handle 15.
  • a receiving recess 49 is formed on the leg 19, which opens into the bayonet receptacle 31 and into which the securing spring 13 is inserted.
  • the shape of the receiving recess 49 is complementary to the shape of the part of the locking spring 13 inserted into it, so that the locking spring 13 does not take up any additional installation space and is securely stored.
  • the fastening section 47 is held securely in the receiving recess 49 by edge sections of the receiving recess 49 which are each formed into a nose 51.
  • An elongated spring arm 53 of the securing spring 13 extends from the fastening section 47 to the bayonet receptacle 31.
  • An end section of this spring arm 53 at its free end (i.e. remote from the fastening section 47) forms the locking tongue 43.
  • the locking tongue 43 has a contour which on the one hand to a contour of the bayonet receptacle 31 and on the other hand to a contour of the bayonet bolt 29, between which the locking tongue 43 is arranged when the bayonet bolt 29 is inserted into the bayonet receptacle 31 and rotated into its coupling position and the locking tongue 43 is in its locking position .
  • the locking tongue 43 is designed as a leg spring, which is inserted into a spring receptacle 55 formed in the leg 19 of the carrying bracket 15 and is supported with a first leg 57 on the leg 19 of the carrying bracket 15, while the second leg 59 of the leg spring is up to extends to the bayonet receptacle 31 and is biased axially in the direction into the bayonet receptacle 31.
  • An end section at the free end of the second leg 59 forms the locking tongue 43.
  • the second leg 59 is bent at its free end in such a way that it is supported on the one hand on a contour of the bayonet receptacle 31 and on the other hand is adapted to a contour of the bayonet bolt 29, between which the locking tongue 43 is arranged when the bayonet bolt 29 is inserted into the bayonet receptacle 31 is inserted and rotated into its coupling position and the locking tongue 43 is in its locking position.
  • the securing spring 13 designed as a leg spring can automatically snap into place behind the positive locking means 35 of the bayonet bolt 29 with its locking tongue 43 when the bayonet lock 27 is closed and thereby reliably secure the bayonet lock 27 against automatic opening.
