Description

Fitting part limiting opening

The present invention relates to window and door fittings. In general, such fittings are used to connect a sash to a frame, the sash being pivotable relative to the frame in order to be able to open and close it, i.e. to create a system between sash and frame. The pivoting movement can relate to different pivoting axes, with vertical pivoting axes being referred to as a rotary opening or closing movement and horizontal pivoting axes with a tilting opening or closing movement or folding movement, depending on whether the pivoting axis is above or below. In this application, the term “pivoting” is used as a generic term for all conceivable axes of rotation for an opening or closing movement of the wing relative to the frame.

In many cases, it is desirable to consider the scope of a

To limit the swing opening movement of the wing, ie to set a maximum opening angle. This applies above all to the tilting movement of window or door sashes with tilt or turn-tilt fittings. For this purpose, conventional folding scissors are used, for example, which can be attached in the upper horizontal fold of a wing and limit the tilt angle during an opening and tilting movement so that only a ventilation tilting position is possible and the fitting due to a too large tilting movement and thus a too large shift in the center of gravity of the wing is not damaged from the frame level. However, many other possible uses are also conceivable in which a limitation of an opening pivoting movement is sought. In addition to the opening scissors for tilt fittings already mentioned, other opening-limiting elements are also known in the prior art. For example, DE 38 20 755 A1 shows an opening limiting element, namely an arm articulated on the frame, with which a locking pin of an espagnolette fitting device on the wing comes into engagement when the espagnolette fitting device is switched into the corresponding tilting position by a fitting actuating element. If an opening and tilting movement is then carried out, the arm is pivoted with respect to the plane of the wing and the plane of the frame, a bearing journal supporting it by engaging in an elongated hole of the arm abutting one end of the elongated hole and the arm corresponding to the length of the elongated hole and the arm length defines a maximum opening tilt angle.

During a closing movement of the wing, the locking pin on the wing comes out of engagement with the arm and into a laterally open area of the arm, so that when the tilting movement is opened again - without actuation of the connecting rod fitting device - no opening-limiting locking by the arm takes place. With this possibility of unlocking the opening limiting element, an escape possibility is to be created for emergency situations. The opening limiting element is designed so that after a closing movement of the wing and an actuation of the connecting rod fitting device in its closed position, there is again such a relative movement between the journal of the arm and the elongated hole that the arm comes into operation again when the wing is opened again.

The invention is based on the technical problem of specifying a fitting part with an opening limiting element which is improved compared to the prior art.

In order to solve this technical problem, a fitting part according to the invention is provided for a window or a door with a wing that can be pivoted about an axis relative to a frame Fitting part has an opening limiting element which is designed to be permanently connected to the frame or sash and to hold the sash or frame in a pivoting opening movement out of a system between the sash and frame at a predetermined pivoting opening position with respect to a further opening movement, characterized in that that the opening-limiting element can be switched by a user into two operating states, wherein when it is switched to a first of the operating states, it has an opening-limiting effect in the above manner, and, if it is switched to the other second operating state, does not have an opening-limiting effect, and the opening-limiting element remains in the respective operating state without user intervention.

Furthermore, the invention is directed to this fitting part comprising window and door fittings and to windows and doors with such fittings.

Preferred configurations of the fitting part and the fitting are specified in the dependent claims.

The basic idea of the invention is that

Opening limiting element by a user permanently out of function and can be put back into function as desired, so that the window or door can be operated as if the opening limiting element were not present at all or had just been reinstalled. This is based on the finding that the possibility provided in the prior art that the opening limiting element can be unlocked for emergencies is unsuitable for everyday use of an opening limiting function because the unlocking process is carried out anew after each actuation of the connecting rod fitting or the fitting actuating element, for example a window handle must become. Furthermore, the process of unlocking is uncomfortable for the user because the entire sash has to be closed and opened again for this purpose. From the combination of the recurring The need to unlock the opening limiting element and the stiffness and cumbersome nature of this process means that it can actually only be a security solution for emergencies.

In contrast, however, the invention enables the opening limiting element to be taken out of operation in everyday use and for a period desired by the user. He has the option of switching the opening limiting element back to the "active" first operating state, if desired, the opening limiting element remaining in its "passive" second operating state until this switching operation, regardless of the window or door operation. This can e.g. be advantageous if a full opening movement of the sash is frequently used and a limited swivel opening position should only be set occasionally, for example in a window that has to be passed through more often, but which should also be able to be brought into a night ventilation position, or in a door , which serves as a passage, but which you also want to give a night ventilation position without providing a complete turn-tilt fitting.

The opening limiting element is preferably designed as an arm, which is articulated either on the frame or on the wing and can be brought into and out of engagement with the respective other part, ie the wing or frame, via a coupling element of the arm. For this purpose, a coupling part which is complementary to the coupling element of the arm is provided on the wing or frame, but can be a conventional part, in particular a fitting part.

It is preferred that the switchability of the opening limitation arm by the user consists in a pivotability from a first to a second position and vice versa, the two positions each being assigned to one of the two operating states. For this purpose, the coupling element of the arm is assigned to the first operating state first position in an area in which it can come into engagement with the coupling part of the wing or frame in accordance with the opening limiting effect, the second position being selected such that the coupling element of the arm then lies outside of this engagement area. In the simplest case, the arm is pivoted about 180 ° around the hinge of its attachment to the wing or frame. Then there must only be enough space for the arm on both sides of the articulated attachment.

The coupling part of the wing or frame can be, for example, a pin for which an engagement recess is provided on the arm as a coupling element of the arm. For this purpose, this engagement recess is preferably arranged on the end of the arm opposite the axis of the bearing on the frame or sash. As a result, the rotation of the arm with respect to the sash level and the frame level does not interfere with the pivot opening movement.

Since the limited opening position predetermined by the opening limiter is often used as a ventilation position, the invention provides as a further embodiment to achieve a certain securing of this position against a closing movement with a latching device. Due to the action of the locking device, a certain minimum force is required to close the sash again. If this minimum force is selected appropriately, the sash can be easily closed again by an operator, but cannot fall due to its own weight and / or air movements, children or other undesirable influences. Preferably, the locking device consists of a spring, e.g. in the engagement recess for the pin.

In the case of a pin as a coupling part of the window or frame, an engagement opening can also be provided on the arm, which is best provided in the vicinity of the axis of the articulated attachment to the frame or sash. Then if the pin is one of a Espagnolette device is driven pin, it can engage in this engagement opening in a closed position of the fitting, whereby the opening limiting element further secures the closed position. It should be noted that the arm protrudes from the point of view of the axis of the articulated fastening beyond the engagement of the pin in the engagement opening and the tilting of this protruding distal end of the arm relative to the sash plane and the sash plane is hindered during an opening movement by the frame or the sash frame , so that a locking effect is created even without locking the articulated bearing of the arm.

With an undercut cross-sectional shape, a complementary cross-sectional shape of the pin can further improve the locking also against movements in the wing and frame planes.

If the mounting of the arm on the frame or sash is somewhat inhibited from rotating, an unintentional change in the switching position of the arm can be achieved. For example, by tilting the wing when the arm is attached to the wing, or by the bumps that occur when the wing moves throughout the wing and frame area and by unintentional slipping along the frame, such an unintentional adjustment may be possible, especially if the Arm pointing upwards in the current switching position. Suitable anti-rotation devices are, for example, spring washers or elastically deformable ones

Plastic bushings in the warehouse, generally elastic locking means.

It is particularly desirable in the invention that at least the fitting part according to the invention with the opening limiting element, for example the arm described, can be fitted completely concealed in a fold. Then the external appearance of the window or door is not disturbed by the additional function of the fitting part according to the invention. In particular, the invention Fitting part can also be completely ignored when not in use and does not raise questions and uncertainties regarding the correct operation of the window or door leaf for users unfamiliar with the function. On the other hand, the fitting element, if it is really to be switched over, is easily accessible in the fold in a partially open sash position, so that there is no impairment in the operability.

According to the invention, the mounting of the fitting element can be facilitated in that an auxiliary assembly device is provided which specifies a fixed relative positional relationship to another fitting part. For example, comes the fitting part into question, which has a connection for a fitting actuating element, for example a coupling for a window or door handle, or a fitting part assigned to this fitting part on the frame. As a rule, special precautions are taken in the sash frame for this fitting part, e.g. Recesses provided, or there is anyway the need for an adjustment to the associated frame-side fitting part. This means that these hardware components form a point of reference for the installation of all other hardware components. By means of the assembly aid device, complicated measuring and marking of the assembly position for the fitting part according to the invention is no longer necessary; rather, with the aid of the assembly aid device it can be applied to a suitable area of the other fitting part serving as a reference point, clamped or the like.

The assembly aid can also be made removable. This has the advantage that different assembly aids can be used for different applications, so that different relative positions can be set in the assembly with the same fitting part according to the invention. In addition, when designing the removable assembly aid device, it can be taken into account that it can be exchanged on the sides, so that a legal Left confusion in the application can be taken into account by simply re-assembling the auxiliary assembly. However, this only applies to asymmetrical assembly aids in this regard, for example a hook, which is the preferred embodiment of the assembly aide in this invention. For the rest, reference is made to the exemplary embodiment.

As already mentioned at the beginning, the invention is also directed to a fitting which, in addition to the fitting part according to the invention, also comprises other fitting parts. This is because the functional properties of the entire fitting are improved by the invention. Correspondingly, this also applies to a window or a door on which such a fitting is mounted, because the window or the door show improved usage properties.

As also already mentioned, the coupling part on the wing or frame is preferably a pin driven by a drive rod device. Accordingly, the fitting according to the invention then also includes the drive rod device with the pin. This can be, for example, a conventional drive rod device of a turn-tilt fitting. The pin can then be a conventional locking pin provided in any case, only a mounting plate with a locking engagement for the locking pin being replaced by the fitting part according to the invention. In this context, it is recalled that an opening limiting arm according to the invention can have a locking engagement opening for the locking pin. As previously mentioned, the locking engagement opening may have an undercut cross-sectional shape; a suitable pin for this then has a mushroom cross-sectional shape at least in a corresponding direction.

A particular aspect of the invention consists in that the fitting according to the invention has, in addition to the opening-limiting fitting part explained above, at least one further second opening-limiting fitting part. Then if the second opening-limiting fitting part allows a more open pivot opening position than the first, the fitting part according to the invention leads through its switchability between the active first and the passive second operating state to a change in the maximum possible pivot opening angle. For example, the tilting angle of a tilting window or a tilting door as ventilation position can be selected to be smaller or larger, depending on whether a larger - in warm weather in summer - or a smaller - in cold weather in winter - air throughput is desired. The fitting according to the invention then has two selectable pivot opening positions.

The second fitting part can, of course, also be a fitting part according to the invention, so that the opening limitation function can be taken out of operation completely again by placing both fitting parts in the second operating state. It is of course also possible to provide a third fitting part with an opening-limiting function, so that three pivot opening positions are then possible.

It is particularly preferred in the invention, however, for the fitting part according to the invention to have an otherwise conventional fitting

Add scissors as an opening-limiting fitting part, so that you can achieve a reduced pivot opening position compared to the function of the opening scissors by the fitting part according to the invention, wherein the pivot opening position of the opening scissors can be selected if desired. This applies in particular to the tilt function of tilt windows and doors.

The invention is illustrated below using an exemplary embodiment which is shown in detail in the figures. Individual features disclosed can also be essential to the invention in other combinations. In particular, the disclosure of the invention in the general representation above as well as below Procedural aspects that can still be used in the production process.

With regard to the details of the window with tilt and turn fitting shown in more detail as an exemplary embodiment, reference is first made to FIG Pre-registration DE 199 1 1 893.0 by the same applicant, the disclosure content of which is included here.

FIG. 1 shows a window 1 with a fixed frame 2 and a wing 3 which can be pivoted against it. The wing 3 can be rotated about a vertical axis 5, which is formed by hinge fittings 4 in the right-hand region of the fixed frame 2.

FIG. 2 shows an alternative pivoting movement possibility. There, the wing 3 can be tilted relative to the fixed frame 2 about a horizontal tilt axis 6 in the lower region of the fixed frame 2. In addition, there is also the rotary opening option from FIG. 1. This window is therefore a tilt and turn window. For this purpose, the window fitting has a conventional opening scissors 7 as an opening limiting element.

In Figure 1, the fitting parts related to the tilting function are omitted. The arrow which can be seen in the right part in FIG. 1 symbolizes the rotary movement of a window handle 16 as a fitting actuating element, by means of which a switch is made between a closed position of the fitting when the wing 3 is in contact with the frame 2, the rotary opening position shown in FIG. 1 and the tilt opening position shown in FIG can. For this purpose, the fitting has connecting rod devices 8 which are guided in a longitudinally displaceable manner, drive the pins 9 and are driven by the symbolized rotary movement via a conventional edge gear 15 of the window handle 16. The pins 9 are associated with engagement elements 10 which secure the closed position of the wing 3.

A fitting part 26 and an opening-limiting fitting part Y according to the invention are also shown in FIGS. 1 and 2. Both are shown in detail in FIG. 3. The fitting part 26 is the frame-side counterpart to the wing-side fitting part containing the window handle 16 and the edge gear 15. The Fitting part Y according to the invention is arranged above the fitting part 26, in such a way that it can cooperate with a wing-side mushroom head pin Z, which is also driven by the drive rod device 8.

According to FIG. 3, the fitting part 26 is a rail with a relief element 35 for the wing 3. For details of the rail 26, in particular an incorrect operation lock, not shown here, and the relief element 35, reference is made to the already cited DE 199 11 893. The perspective of Figures 3 to 8 is chosen so that the wing 3 opens to the left. According to FIGS. 3 to 8, the representation in FIGS. 1 and 2 looks from the right onto the left frame spar. The opening-limiting fitting part Y is to be attached according to FIG. 3 above the rail 26. There are basically three options. The variant shown in the middle in FIG. 3 provides that the fitting part Y is attached to the frame without a physical connection to the rail 26, whereby it must be aligned in a suitable manner so that it is aligned with the position of the locking pin Z. As an alternative to this, however, the invention provides for a removable hook V to be provided on the element Y as an assembly aid element, which can be inserted into a corresponding receptacle in the rail 26. The inclusion in the rail 26 is shown with O. An exact relative position between the fitting part Y and the rail 26 is thereby predetermined.

The hook V is attached to the mounting base plate T by a plug connection, for which purpose a web running perpendicular to the mounting base plate T is provided. The hook V can thus also be attached to the mounting base plate T from the other side, so that the fitting part Y can be used both for windows 1 opening to the right and to the left.

If larger distances between the rail 26 and the fitting part Y are desired, intermediate elements W can also be used, as can be seen in the illustration on the right in FIG. 3. These elements W can also be attached to the rail 26 and in turn offer a receptacle for the hook V. The exact specification of a relative position by the assembly aid, namely the hook V and the intermediate element W, simplifies the attachment of the fitting part Y according to the invention because it is not measured separately and must be marked. Rather, because of its interaction with the fitting part of the edge gear 15, the rail 26 is to be mounted aligned with it anyway, which can easily be done, for example, with the relief element 35. Then an adjustment of the fitting part Y to the edge gear 15 is predetermined by the hook V, possibly in connection with an intermediate element W. Since the locking pin Z is also adjusted to the edge gear 15 via the drive rod device 8, a functionally appropriate positional relationship between the fitting part Y and the locking pin Z is thus also ensured.

The structure of the fitting part Y according to the invention is shown in detail in FIGS. 5, 6 and 7. It has a mounting base plate T, to which an opening limiting arm Q is pivotably articulated via an axis S. In this embodiment, the arm Q points downward from the axis S when it is in the position corresponding to the active first operating state. FIG. 4, which otherwise corresponds to the left representation in FIG. 3, additionally contains in the upper region a representation of the second passive position of the arm Q, in which it points upwards from the axis S.

The arm Q has an engagement recess P at its distal end

Coupling element for the locking pin Z. The engagement recess P is shown in section in FIG. It can be seen that a spring M is provided in the area of the engagement recess P, which delimits the cross section of the engagement recess P, which is undercut. In the end region, the cross section released by the spring M tapers a little further, in order to thereby define a closing section L. The engagement recess P is essentially formed in that the spring M from a material section rising from the arm Q at the end and is bordered by two mutually facing rotating corners. This is shown in Figures 5 and 7.

Adjacent to the axis S, the opening limiting arm Q has a further engagement recess, namely a locking engagement recess O. It is shown in cross section in FIG. 6, an undercut cross section also being selected here. The arm Q has a laterally open area N between the recesses O and P.

The mounting base plate T is screwed onto the frame 2 by means of corresponding holes. The opening limitation arm Q is articulated on the mounting base plate T with a plastic bushing which is slightly rotationally inhibited. As a result, it maintains the positions shown in FIG. 4 despite the effects of gravity, vibrations and other disturbances. Instead of the rotation inhibition of the axis S, a latching device or other fastening device can also be provided, which holds the opening limiting arm Q in the respective first or second position.

FIG. 4 shows three positions A, B, D of the locking pin Z offset to the right relative to the opening limiting arm Q. The offset to the right serves to make the drawing easier to read. In fact, in the perspective of FIG. 4, the positions A, B and D lie in the region of the arm Q. It can be seen that the locking pin Z engages in the locking recess O in a closed position A. In a rotational opening position B, the locking pin Z is arranged in the laterally open area N. In a tilt opening position D, it engages in the engagement recess P.

Figures 8 and 9 illustrate the interaction of the opening limiting arm Q with the locking pin Z. In Figure 9 you can see in a 90 ° rotated perspective that the locking pin Z is in the opening position B in the side open area N, so that the window corresponding to Figure 1 rotatably pivoted about axis 5 can be. Irrespective of whether the opening limitation arm is in the first or the second operating state, there is no opening limitation effect.

When the locking pin Z is in the tilt opening position N, it engages in the engagement recess P, specifically in the area of the spring M. If the leaf 3 is pivoted about the axis 6 according to FIG. 2, the opening limiting arm Q in FIG. 8 becomes corresponding deflected relative to the plane of the wing 3 and the frame 2. For this purpose, the tilt opening position D of the locking pin Z is arranged somewhat above the lower end L of the engagement recess P. Therefore, the pin Z can still slide into the end region L of the engagement recess P during the tilt opening movement. Once there, the pin Z abuts so that the opening limiting arm Q secures the wing 3 against a further tilting opening movement by a coupling between the axis S and the axis formed by the engagement of the pin Z in the engagement recess end L.

The end L of the engagement recess P is designed by the shape of the spring M as a latching position, so that the wing 3 can only be tilted back with the application of a certain minimum force. For this purpose, the pin Z must pass through the tapering of the spring M over the end L of the engagement recess P, thus bending the spring M somewhat apart.

When the locking pin Z is in the closed position A, it engages in the locking recess O. This intervention serves - in addition to the locking by the pin 9 and the corresponding locking interventions 10 (Figures 1 and 2) - as additional security. In this position of the locking pin Z, the opening limiting arm Q cannot be pivoted with respect to the plane of the wing 3 and the frame 2, because the limiting arm Q abuts the walls of the wing rebate. Both in the closed position A and in the tilt opening position D, the pin Z is secured against lateral movement out of the recess O or P because of its mushroom shape. For this purpose, the recesses O and P, as already mentioned, are undercut in cross section.

When the opening restriction arm Q is in the second position indicated in Figure 4, i.e. points upwards from axis S, it is in the second passive operating state. Then the locking pin Z does not interact with the opening limiting arm Q regardless of the position of the locking pin Z. This passive second operating state is maintained until a user manually switches the opening limitation arm Q from the second to the first position, i.e. swings downwards by 180 °. In the resulting first position, the opening limitation arm Q is in the active first operating state in order to cooperate with the locking pin Z in the manner shown. This operating state is also maintained until a user swings the arm back up to the second position by 180 °. The opening limiting arm Q, more generally the opening limiting element, thus forms an actuating element for switching between its operating states, the operating states being switched on permanently, i.e. cannot be left independently or by other operations on the fitting of window 1.

The tilt opening position shown in FIG. 2 is defined by the opening limiting scissors 7 shown. The tilt opening position predetermined by the opening-limiting fitting part Y is open by a smaller gap than shown in FIG. 2. The exact height of the tilt opening position can be specified by the mounting height of the fitting part Y, the length of the opening limiting arm Q and the distance of the position D of the locking pin Z from the axis S. In the assembly shown together with the opening limiting scissors 7, switching the Opening-limiting fitting part Y between the first and the second operating state, the opening angle of the tilt opening changes, namely between the angle predetermined by the fitting part Y and the opening scissors 7 limiting the opening.

Instead of the stay scissors 7, another opening-limiting fitting part, for example a further fitting part Y according to the invention, could of course also be provided, a different angle being able to be defined by changing one of the geometric sizes mentioned. However, it is also possible to use the fitting part Y according to the invention for a rotary opening movement, as shown in FIG. 1. For this purpose, the fitting part Y would have to be designed so that the opening-limiting effect takes place in the rotational opening position B of the locking pin Z or another pin. For example, the opening restriction arm Q could be mounted to point upward from the axis S in the active first position, with the

Locking recess O could be omitted. Then the locking pin Z would be in position B in engagement with the engaging recess P and in position D would be in the laterally open area N. In the second passive operating state, one will usually want to allow an unlimited rotary opening movement of the leaf 3, that is, no further opening-limiting Provide fittings.

The invention can also be used with pure turn or tilt windows, in which case the laterally open area N could be retained in order to bring the locking pin Z out of engagement with the opening limiting arm Q in an intermediate position of the locking pin Z between a closed position and an open position to, so that the arm Q can be switched.

Regardless of the exact application for tipping or

In any case, the opening-restricting fitting part serves to determine the opening of the opening, in which a limited air exchange can take place for ventilation purposes, the sash but is not fully open. There is still a certain amount of security against burglary. In conjunction with another opening-limiting element, for example the stay scissors 7, different gap opening positions can be used, for example to adapt to the external weather conditions, i.e. that in cold weather in winter with the fitting part Y a slightly open gap opening position is selected, while in warmer weather in summer a more open gap opening position is produced with the stay scissors 7.
