Description

The present invention relates to a closing part for a window or door fitting, in particular for a window or door fitting, which is designed for internal arrangement in the area between the folds of the sash and the frame of the respective window or the respective door. A locking part according to the preamble of claim 1 is from GB 2,448,340 A known. A window or door fitting of the type mentioned usually comprises a fitting arrangement which is to be installed in a groove running in the sash rebate and which has locking elements that can be adjusted manually or by motorized means by means of a drive mechanism, as well as a locking part which is to be installed in the frame rebate and a or has a plurality of receptacles into which a respective one of the locking elements can engage, depending on the set position, in order to lock the sash on the frame. In principle, the adjustable fitting arrangement with the locking elements on the frame and the locking part on the sash could also be provided in reverse.

The locking elements are typically locking pins that protrude vertically from an adjustable drive rod to which they are attached and can be moved over the drive rod in the direction of the longitudinal extension of the drive rod. The locking pins can also be designed as roller pins, in which a rotatable roller is arranged on the head of the respective pin, which can roll on the edges when engaging in the respective receptacle of an associated locking part, so that friction can be avoided compared to rigid locking pins.

If the roller or, in the case of rigid locking pins without a roller, the head of the locking pin has a constant diameter, the locking pin can accommodate the in which he intervenes, in principle also in the direction of its longitudinal axis, i.e. transversely to its actual direction of movement. It is thus possible to pry open or pry open a wing that is locked by means of such locking pins, since the prying or levering increases the distance between the wing and the frame, as a result of which the locking pin leaves the associated receptacle and the lock is thus released.

In order to improve the security of the lock, it is therefore advisable to use fittings that have mushroom-headed pins as locking pins. Mushroom pegs are characterized in that they have a head with a diameter that is enlarged at least in some areas. The enlarged diameter can advantageously be formed on a rotatably mounted roller on the head of the locking pin. The mushroom head pin and the associated receptacle are designed relative to one another in such a way that the mushroom head pin, when it is received in the receptacle, engages behind the edges of the receptacle with the enlarged diameter in such a way that it is not possible to move it transversely to its actual direction of movement, in particular in the direction its longitudinal axis to move out of the receptacle. In this way, the mushroom head cams prevent the locking pin from disengaging the locking part when an attempt is made to pry open or pry open the sash.

Since a significant improvement in security is achieved by means of mushroom cams, not only are new windows and doors preferably provided with appropriate fittings, but already installed windows and doors are retrofitted with appropriate fittings. Even with new windows and doors, but especially with older windows and doors to be retrofitted, the problem is that there are a large number of different sash and frame profiles, so that suppliers of window and door fittings have to provide numerous different fittings that match the different profiles are adapted in each specific way. This causes a certain production and storage effort. The assembly is also complex because the fitting that is suitable for the respective profile must first be determined and then may not be immediately at hand.

The locking parts of a fitting to be installed must be adapted to the respective profile of the window or door sash or frame, in particular with regard to the positioning of the receptacle provided by the locking part for the engagement of a bolt pin and with regard to reliable fastening of the locking part to the frame. For this purpose, the underside of a respective locking part can be designed so that it is complementary to the respective profile on which it is to be arranged that, with an essentially precisely fitting arrangement, a reliable fit of the locking part on the profile and, at the same time, a defined positioning of the relevant receptacle of the locking part is achieved. In this case, however, a different locking part with a specific underside for the respective profile shape must be provided for each profile shape. This disadvantage is reduced by a closing part, on the underside of which different bases can be attached as a kind of adapter for different profiles, but not entirely avoided, since a large number of different bases suitable for the different profiles still have to be provided.

It is an object of the invention to provide a closing part for a window or door fitting which can be used as universally as possible on various window or door leaf or frame profiles, in particular for interaction with mushroom pins of the respective fitting.

The object is achieved by a closing part with the features of claim 1. Advantageous embodiments emerge from the subclaims, the present description and the figures.

The closing part according to the invention extends in a longitudinal direction and has a first side surface and a second side surface, the first side surface and the second side surface being aligned parallel to and opposite to one another in the longitudinal direction. Consequently, the first side surface and the second side surface are also parallel to one another, but point in the opposite direction transversely to the named longitudinal direction. Furthermore, a first receptacle extending parallel to the longitudinal direction extends into the first side surface and a second receptacle extending parallel to the longitudinal direction extends into the second side surface. The first receptacle and the second receptacle preferably each have an at least substantially straight course that is oriented parallel to the longitudinal direction. For example, the first receptacle and the second receptacle can each have a constant width, i.e. extension transversely to the longitudinal direction, so that the respective receptacle has two opposite edges that are parallel to the longitudinal direction. However, the width of the respective receptacle does not have to be constant, but can also, in particular the further the receptacle extends into the respective side surface, narrower, symmetrically or on one side, so that the locking pin assigned to the respective receptacle engages in the receptacle tightening the sash against the frame.

The first receptacle and the second receptacle are each designed as an elongated hole which is open on one side and whose longitudinal extent can be parallel to the aforementioned longitudinal direction. An assigned locking pin can then engage in the respective receptacle either in the longitudinal direction or counter to the longitudinal direction through the open end. The first receptacle and the second receptacle preferably each extend into the side surface from an edge of the side surface pointing in the longitudinal direction or counter to the longitudinal direction, so that the respective receptacle is open towards this edge. In the opposite direction, ie in the direction of the extension of the respective receptacle, on the other hand, the respective receptacle is closed, so that it represents a dead end for a possibly assigned locking pin.

The first receptacle and the second receptacle are each designed to receive a locking pin, in particular a mushroom pin, of the fitting. In particular, the first receptacle and the second receptacle are each designed to receive a mushroom pin of the fitting so that it engages behind opposite edges of the respective receptacle, which delimit the receptacle transversely to the longitudinal direction, when it is received in the respective receptacle. The introduction of an associated locking pin into the respective receptacle preferably takes place in each case along the longitudinal direction, i.e. in the longitudinal direction or precisely opposite to it.

According to the invention, the first receptacle and the second receptacle are arranged offset from one another in a transverse direction that is aligned parallel to the side surfaces and transversely to the longitudinal direction, preferably by at least 1 mm, particularly preferably by at least 2 mm, in particular by at least 4 mm. The offset between the first receptacle and the second receptacle is defined in particular with reference to a center line of the respective receptacle, which, at least for receptacles of constant width, is preferably the same distance from the two edges of the respective receptacles and can correspond to a mirror axis of the respective receptacle.

The closing part is preferably designed to be arranged on the frame of the respective window or the respective door, while a corresponding fitting arrangement, which has a locking pin cooperating with the closing part, is arranged on the sash. In principle, however, it can also be provided that the closing part is arranged on the sash and the corresponding fitting arrangement is arranged on the frame in reverse.

The closing part can in particular be attached to the frame (or when the closing part is attached to the sash: towards the sash) with one of the two named side faces facing the frame and at least partially bear against it, while the other side face towards the sash (or when the Closing part on the sash: to the frame) of the respective window or the respective door and which provides at least one receptacle formed on this side surface for interaction with a locking pin. Of the first receptacle formed in the first side surface and the second receptacle formed in the second side surface, only either one or the other is actually used as a receptacle. Which it is depends on how the locking part is attached to the frame (or sash).

The closing part is advantageously designed in such a way that it can be mounted not only in one orientation but also on the envelope and consequently has at least two possible mounting orientations. In one assembly orientation, the first side surface represents the top of the locking part, on which the first receptacle is available for engagement of an associated locking pin, while the second side surface represents the bottom of the locking part, with which the locking part on the frame (or on the sash ) is attached. In the other assembly orientation, on the other hand, the upper side of the closing part is formed by the second side surface and the lower side of the closing part is formed by the first side surface.

The offset between the first receptacle and the second receptacle has the consequence that the position of the receptacle available for engagement of an assigned locking pin depends on the orientation in which the locking part is mounted. In this way, the closing part can be adapted to at least two different so-called groove center positions of respective window or door profiles. The offset between the first receptacle and the second receptacle is preferably selected so that at least the two most common Groove center layers are covered. In addition, since minor deviations can be compensated for by existing play or an adjustment of the position of the respective locking pin on the drive rod, which is often possible within certain limits, the locking part can also cover more than exactly two different groove center positions. In this respect, the locking part according to the invention can be used largely universally on various window and door profiles.

According to an advantageous embodiment, in addition to the first receptacle, a third receptacle, which also runs parallel to the longitudinal direction, extends into the first side surface. It is also preferred here if, in addition to the second receptacle, a fourth receptacle, again running parallel to the longitudinal direction, extends into the second side surface. Consequently, the first side face and the second side face then each have at least two receptacles. Depending on the side surface with which the locking part is attached to the frame (or on the sash), at least two receptacles for the engagement of a locking pin can then be available on the opposite side surface.

In principle, the first receptacle and the third receptacle, as well as the second receptacle and the fourth receptacle, if present, can be offset from one another in the transverse direction in order to provide receptacles at different positions on the respective side surface. As an alternative to this, however, the first receptacle and the third receptacle are not arranged offset from one another in the transverse direction and the second receptacle and the fourth receptacle, if present, are also preferably arranged not offset from one another in the transverse direction. Thus in each case two receptacles provided on the same respective side surface of the closing part are arranged identically with regard to their position in the transverse direction. In particular, the two receptacles provided on the same respective side face of the closing part can be parallel along the same to the longitudinal direction Straight lines. The two recordings of a respective side surface can in this way be adapted to the same respective groove center position of the window or door profile.

According to a further advantageous embodiment, the third receptacle and the fourth receptacle are each designed as an elongated hole that is open on one side. In particular, such an elongated hole can either be open in the longitudinal direction and closed in the opposite direction or, precisely conversely, closed in the longitudinal direction and open in the opposite direction. The course of a respective such receptacle can then also be defined by the connection between the open and the closed end of the elongated hole. The fact that a receptacle is open on one side means in particular that a locking pin, in particular a mushroom head pin, can be inserted into the receptacle from this side or leave the receptacle on this side, which is not possible on the closed side. In order to be open on one side, the respective elongated hole can, for example, simply open onto a corresponding edge of the side surface in which it is formed.

In such an embodiment, the first receptacle and the third receptacle preferably extend opposite one another into the first side surface. This means that one of these two receptacles is open in the longitudinal direction and closed against the longitudinal direction, whereas the other of the two receptacles is closed in the longitudinal direction and open against the longitudinal direction. In this way, two receptacles for receiving an assigned locking pin from two different directions can be available on the first side surface. This further improves the flexible usability of the locking part, since it can be used regardless of the direction in which, parallel to the longitudinal direction, the locking pins are adjusted when locking or unlocking. In order to achieve this advantage for both assembly orientations (normal orientation or on envelope), the second side surface be designed in a corresponding manner. The second receptacle and the fourth receptacle then extend opposite one another into the second side surface, in particular starting from a respective edge of the side surface in opposite directions or with the open side pointing in opposite directions.

The first receptacle and the third receptacle or the second receptacle and the fourth receptacle can extend towards one another, for example. A locking pin can then engage in the first side surface or in the second side surface, parallel to the longitudinal direction, either from one side or from the opposite side. As an alternative to this, it can also be advantageous if the first receptacle and the third receptacle or the second receptacle and the fourth receptacle extend away from one another. The locking pin can then engage from a center between the two receptacles either in the longitudinal direction into one receptacle or against the longitudinal direction in the other receptacle. Such an embodiment can be particularly useful when the locking pin is movable between a central unlocking position and two different locking positions which are on opposite sides of the unlocking position and in which the locking pin is to engage in the locking part in a locking manner, for example in one locking position To lock the wing completely and in the other locking position a partial opening, for example a tilt opening, to allow the wing.

The said recordings preferably correspond to one another in terms of their shape. This applies in particular to the first recording and the second recording. In addition, if available, it can also be used for the third recording and the fourth Record apply so that the recordings have the same shape at least in pairs. In particular, all four recordings can correspond to one another in terms of their shape. Recordings that correspond to one another with regard to their shape can, for example, have an identical shape or at least a mirror-symmetrical shape to one another. For example, the receptacles can each have a punching contour, the punching contours of receptacles, which correspond to one another in terms of their shape, are then preferably identical or mirror-symmetrical to one another.

According to a further advantageous embodiment, the closing part has a narrow side which is oriented perpendicular to the first side surface and to the second side surface and delimits the closing part in the transverse direction, the first receptacle, as well as, if applicable, the third receptacle, a distance of at most 11 mm, in particular between 8.5 mm and 9.5 mm, for example of about 9 mm, to the narrow side and the second receptacle, as well as optionally the fourth receptacle, a distance of at least 11 mm, in particular between 12.2 mm and 13.8 mm, for example of about 13 mm, to the narrow side. These distances have proven to be useful in order to cover the most common slot center positions of various window or door profiles. Such a closing part can then also be used on profiles which actually require slightly different distances of, for example, 12.4 mm or 13.1 mm instead of the 13 mm mentioned. With regard to the respective receptacle, the stated distances preferably relate to a center line of the receptacle, in particular running in the longitudinal direction, and, with regard to the narrow side, preferably to an outwardly facing surface of the narrow side of the closing part.

The designation as "narrow side" basically only serves to distinguish the narrow side from the named side surfaces of the closing part. The narrow side therefore does not necessarily have to be narrower than the side surfaces being. However, the narrow side is preferably narrower, based on the respective extent transverse to the longitudinal direction, than the first side surface and than the second side surface. In particular, the height of the closing part can be defined by the width of the narrow side. This can be, for example, 8.5 mm, so that the closing part can be mounted between the frame and the sash, between which there is typically about 12 mm to 13 mm rebate clearance. The narrow side can also serve as a reference point for the arrangement of the closing part on the frame (or sash) of the respective window or the respective door. For example, the closing part can be designed to be arranged with the narrow side at least essentially flush with an inner front edge of the frame profile (or wing profile). This front edge can be formed, for example, on a web which delimits a groove in the profile into which the locking part is screwed.

Furthermore, it is advantageous if the closing part is designed symmetrically with respect to a mirror plane perpendicular to the longitudinal direction. Such a symmetrical design can further increase the flexibility of the use of the closing part, for example because it can then be used equally well on mutually mirror-symmetrical variants of window or door profiles, e.g. for left- or right-opening sashes. If a third receptacle is formed in the first side surface, this can be designed and arranged mirror-symmetrically to the first receptacle. If a fourth receptacle is formed in the second side surface, this can be designed and arranged mirror-symmetrically to the second receptacle.

According to an advantageous embodiment, the first side surface and the second side surface each have one or more holes, one or more continuous channels being formed by a hole in the first side surface and a hole provided at a corresponding point in the second side surface. These channels preferably extend from one side of the closing part to the other side of the locking part completely through the locking part. The channels can in particular run perpendicular to the first side surface and to the second side surface; but they can also be aligned obliquely to the side surfaces. Such channels can then serve to fasten the closing part to the frame (or sash) of the respective window or the respective door, for example by fastening the closing part by means of screws which each extend through one of the continuous channels. Depending on the shape and / or orientation of the respective channel, oblique screw connections can also be possible. The holes are advantageously placed in the side surfaces so that the closing part can be attached to as many different typical profiles as possible.

In this context, an embodiment is particularly advantageous in which the closing part has a narrow side, in particular a narrow side of the type described above, which is oriented perpendicular to the first side surface and to the second side surface and delimits the closing part in the transverse direction, wherein in the the first side surface and in the second side surface at least two adjustment holes are provided which are at the same distance from the narrow side, this distance being less than the distance between the first receptacle and the narrow side and / or less than the distance between the second receptacle and the narrow side; wherein at least one fixing hole is provided at a distance from the narrow side in the first side surface and in the second side surface, this distance being greater than the distance between the first side surface and the narrow side and / or greater than the distance between the second side surfaces and the narrow side is; and wherein at least one spacer hole is provided at a distance from the narrow side in the first side surface and in the second side surface, this distance being greater than the distance of the first receptacle from the narrow side and / or greater than the distance of the second receptacle from the narrow side is. Preferably there are at least two each in the first side face and in the second side face Fixing holes are provided which have the same distance from the narrow side. Furthermore, in each case at least two spacer holes are preferably provided in the first side surface and in the second side surface, which spacer holes are at the same distance from the narrow side.

The designations of the holes as adjustment hole, fixing hole or spacer hole in each case basically only serve to distinguish the holes in terms of terms, without necessarily implying a specific function or structural design. Holes that are conceptually differentiated in this way can, but do not necessarily have to, differ in terms of their function and / or structural design.

The locking part does not necessarily have to have all three types of holes mentioned, but can also only have holes of two or even only one of these types. The adjustment holes and the fixing holes are preferably used to accommodate screws. For this purpose, the adjustment holes and the fixing holes can in particular have smooth, circumferential walls and / or, in order to be able to countersink the respective screws, can have an outwardly conical mouth or can also be conical as a whole. The spacer holes, on the other hand, are preferably used to accommodate spacers that support the locking part against the frame or the sash, whereby by choosing different spacers, in particular spacers of different lengths, or by using length-adjustable spacers, an adaptation to the distance to be bridged between the locking part and the Frame or to the wing is made possible. Such an adaptation can additionally or alternatively also be achieved in that the respective spacer is inserted into the respective spacer hole to different extents, for example inserted or screwed in or fastened therein in some other way.

The spacers, for the reception of which the spacer holes can be designed, can, for example, be threaded pins. To accommodate such threaded pins, the spacer holes can each have a thread, preferably a fine thread, on their circumferential walls. The thread of a spacer hole formed in the first side surface and the thread of a spacer hole formed at a corresponding point in the second side surface are preferably matched to one another in such a way that these two spacer holes form a continuous thread channel for a respective threaded pin.

As an alternative to being designed as a threaded pin, however, a respective spacer can also be designed in a different manner. In principle, any means come into consideration that enables reliable support with respect to the frame or the sash over the respective distance between the closing part and the profile of the frame or sash. For example, a spacer can comprise one or more washers or spacer sleeves, through which a screw, a fixing pin or the like can extend, which can then additionally reach through two corresponding spacer holes of the first and second side surfaces. The spacer can also comprise a spacer element, for example designed as a block, for example made of plastic, which has one or more pin-like extensions. The closing part can then be plugged onto the pin-like extensions with its spacer holes. Then protruding ends of the extensions can be cut to length, if necessary. Furthermore, a spacer can be designed as a latching pin, on which several latching elements are formed, which engage behind the respective spacer hole after they have been passed through it, so that such latching pins are pushed differently through the spacer holes, similar to a cable tie, into the opposite one Direction but can no longer be pulled out again.

The distances between the holes or the receptacles on the one hand and the narrow side on the other hand are with respect to a respective hole preferably on a center point of the hole, with respect to a respective receptacle preferably on a, in particular running in the longitudinal direction, center line of the receptacle and with regard to the narrow side preferably on a outer facing surface covered on the narrow side. The adjustment holes are preferably both closer to the narrow side than the first receptacle and closer to the narrow side than the second receptacle. The fixing holes as well as the spacer holes are each preferably both further away from the narrow side than the first receptacle and further away from the narrow side than the second receptacle.

Because the adjustment holes and the fixing holes, which can each be provided for screws, are arranged on different sides of the receptacles due to the arrangement described above, a particularly stable fastening of the closing part can be achieved. The adjustment holes can be provided in particular for screws that are screwed into a groove formed in the respective frame profile (or wing profile). In the area of the adjustment holes, the locking part can advantageously lie directly on the edges of such a groove. Because at least two adjustment holes are formed in the first side surface and in the second side surface, through which two channels can be formed for a respective screw, not only the position of the closing part, but advantageously can also be adjusted by screwing two screws into the groove the angular alignment of the locking part relative to the groove can also be reliably determined.

The fixing holes can form channels for screws that can be screwed into another part of the profile that is differently shaped for different profiles. In the area of the fixing holes between the locking part and the profile, depending on the profile, different distances have to be bridged. Depending on the distance, screws of different lengths can be used. In order to reliably support the closing part over the respective distance from the profile, one or more spacer holes are preferably also provided on the same side relative to the receptacles as the fixing holes, each of which can form continuous channels for spacers, in particular threaded channels for threaded pins. By threaded pins that have different lengths and / or can be screwed differently into the respective thread channel and consequently can protrude differently on the respective underside of the locking part, or by different types of spacers, such as spacers of one of the types described above, which also have variable distances can bridge, the locking part can be flexibly supported on the profile over various distances. Overall, a reliable fastening of the locking part that can be adapted to different profiles and is achieved in each case.

According to a further advantageous embodiment, the cross section of the closing part is rectangular, in particular in relation to a section perpendicular to the longitudinal direction. Two opposite edges of the rectangular shape can then correspond to the first side surface or the second side surface, while one of the two remaining edges, which are preferably the shorter edges of the rectangular shape, can correspond to the mentioned narrow side of the closing part. The edge opposite to this can correspond to a further narrow side of the closing part. The rectangular shape can have rounded corners. All corners do not necessarily have to be rounded. At least three corners are preferably rounded.

According to a preferred embodiment, the closing part has a circumferentially closed tubular shape, in particular with a central passage which extends in the longitudinal direction through the closing part. The tube shape must not necessarily have a circular cross-section, but can, in particular, as explained above, have a rectangular cross-section or also another cross-section. The closing part preferably extends at least substantially along the contour of the respective cross section, while the inner surface of the cross section is free and forms the said central passage. The cross section is preferably at least substantially constant over the entire extent of the closing part in the longitudinal direction, in particular apart from the receptacles and holes provided.

To form the tube shape mentioned, the closing part can be formed, for example, from a sheet metal which is bent over into the circumferentially closed tube shape. To form a tubular shape with a rectangular cross-section, three bends of approximately 90 ° each can be sufficient. The receptacles and holes to be provided in the first side surface and in the second side surface of the closing part can then be made relatively easily in the still flat sheet metal. This can be done in particular by punching or cutting, but in principle also by machining. The design of the closing part as a bent sheet metal advantageously enables a particularly efficient production of the closing part in a progressive composite by means of a progressive composite tool which can punch and at least partially deform the sheet metal. The locking part can be largely completed by means of a single tool. A second work step is then advantageously only required for the complete reshaping and, if necessary, for connecting the two side edges which meet due to the reshaping of the sheet metal to form the circumferentially closed tubular shape.

In connection with the connection of the two side edges, a further embodiment is advantageous in which the sheet metal has a first side edge running parallel to the longitudinal direction and a first side edge opposite thereto, parallel to the longitudinal direction running second side edge, the first side edge and the second side edge adjoining each other, and wherein a tab is formed on the first side edge and a tab receptacle is formed on the second side edge, in which the tab engages, preferably with a positive fit, around the first side edge and attach the second side edge together. When the sheet metal is still flat, the first side edge and the second side edge point in opposite directions, in particular transversely to the longitudinal direction. When the circumferentially closed tubular shape is present, so that the first side edge and the second side edge are adjacent to one another, the second side edge is opposite with respect to the circumferential direction of the first side edge. The engagement of the tab in the tab receptacle serves to reliably hold the first side edge and the second side edge together so that the seam of the tubular shape running between the first side edge and the second side edge does not widen or widen, if possible, even when a force is applied, e.g. when attempting to break open the sheet metal can even be bent up completely.

The tab and the tab receptacle can in principle also be designed as a hook or eye, the hook then being able to engage in the eye, in particular in the radial direction with respect to the tubular shape. Preferably, the tab receptacle engages behind the tab receptacle in a form-fitting manner, but in the longitudinal direction. A section of the tab protrudes in the longitudinal direction or opposite to the longitudinal direction over an edge of the tab receptacle, so that the tab cannot be guided past this edge in the circumferential direction. The tab can, for example, have a T-shape and with the oppositely oriented ends of the spar of the T-shape engage behind a respective edge of the tab receptacle both in the longitudinal direction and counter to the longitudinal direction, so that the tab only in the radial direction into the tab receptacle or out of the Tab holder can be moved, but not in the circumferential direction.

More than one tab and more than one tab receptacle can also be provided on the side edges in order to connect the side edges to one another at several points. In principle, the fastening of the two side edges to one another can be based exclusively on the interaction of at least one tab with at least one tab receptacle. As an alternative or in addition to this, the first side edge and the second side edge can also be connected to one another by other structures, e.g. by locking, or otherwise, e.g. by welding. The connection is preferably a form-fit or material fit.

The tubular shape of the closing part can, however, also be achieved in other ways than by means of a bent sheet metal. According to an alternative advantageous embodiment, the closing part is formed from a, preferably drawn or extruded, tubular profile. The tubular profile can in particular be designed as a rectangular profile. In such a raw profile, receptacles and holes can also be made, in particular by punching or machining. Since the tube shape is already available during machining, machining may be more laborious than with an initially flat sheet. Instead, the pipe profile does not have a seam and can therefore be more resistant to being broken open.

The invention is explained in more detail below, merely by way of example with reference to the figures, which each show an embodiment of the locking part according to the invention in a schematic perspective illustration.

The embodiments of a locking part 11 according to the invention shown in the figures are each a locking part 11 for a window or door fitting, which is designed to be fastened to the frame of the respective window or the respective door in order to be there with an associated locking pin , in particular mushroom studs, an adjustable fitting arrangement to be mounted on the sash of the respective window or door. For this purpose, the locking part 11 has a first side surface 13 and a second side surface 15 opposite thereto, in each of which two receptacles 17, 19, 21, 23 are formed, into which a respective locking pin can engage in a locking manner.

The locking part 11 can be attached to the respective frame in two different mounting orientations. In an initial mounting orientation that is shown in Fig. 1 For a first embodiment, the closing part 11 is fastened to the frame in such a way that the second side surface 15 forms the underside of the closing part 11 facing the frame and preferably rests at least partially on the frame, while the first side surface 13 forms the upper side of the closing part 11 whose receptacles 17, 21 formed therein are available for the engagement of a respective locking pin. If, on the other hand, the locking part is mounted on the envelope, it has the in Fig. 2 for the first embodiment shown alternative mounting orientation in which it is compared to the in Fig. 1 The orientation shown is rotated by 180 ° about the axis of rotation D shown as a dotted line with a rotating arrow. This then forms the first side surface 13 the bottom of the locking part 11 facing the frame and preferably resting at least partially on the frame, while the second side surface 15 forms the top of the locking part 11, which provides the receptacles 19, 23 formed therein for the engagement of a respective locking pin.

The closing part 11 extends in a longitudinal direction L (cf. Fig. 1 ) and has a tubular shape with an essentially rectangular cross section which is essentially constant over the entire length of the closing part 11. The first side surface 13 and the second side surface 15 correspond to the two longer edges of the rectangular shape. At their edges running parallel to the longitudinal direction L, the side surfaces 13, 15 are connected to one another by a first narrow side 25 and a second narrow side 27, which correspond to the two shorter edges of the rectangular shape, which have a length of approximately 8.5 mm. This length defines the height of the closing part 11, which corresponds to the distance between the outwardly facing surfaces of the two side surfaces 13, 15.

The receptacles 17, 19, 21, 23 are each designed as an elongated hole which, starting from a respective edge of the respective side surface 13, 15, extends parallel to the longitudinal direction into the respective side surface 13, 15 and ends within the respective side surface 13, 15. The length and the shape of the elongated hole is the same for all receptacles 17, 19, 21, 23. Because the elongated holes each open into an edge of the respective side surface 13, 15, they are open on one side, so that a locking pin can be received in the respective receptacle 17, 19, 21, 23 at the open end. The associated locking pin is preferably designed as a mushroom head pin whose mushroom head has a maximum diameter that is greater than the width of the receptacles 17, 19, 21, 23 transversely to the longitudinal direction L, so that the mushroom head pin, when it is in a respective receptacle 17, 19, 21, 23 is added, opposite and behind edges of the receptacle 17, 19, 21, 23 parallel to the longitudinal direction L and thereby the receptacle 17, 19, 21, 23 not perpendicular to the respective side surface 13, 15, but only along the longitudinal direction L over the open end of the receptacle 17, 19 , 21, 23 can leave.

In the first side surface 13, the first receptacle 17 and the third receptacle 21 extend opposite one another, so that their open ends move away from one another along the longitudinal direction L (cf. first and second embodiment according to FIG Figs. 1 and 2 or. Fig. 3 ) or towards each other (cf. third embodiment according to FIG Fig. 4 ) point. In a corresponding manner to this, the second receptacle 19 and the fourth receptacle 23 also extend opposite one another in the second side surface 15, so that their open ends move away from one another along the longitudinal direction L (cf. first and second embodiment according to FIG Figs. 1 and 2 or. Fig. 3 ) or towards each other (cf. third embodiment according to FIG Fig. 4 ) point.

The first receptacle 17 and the third receptacle 21 point with respect to a transverse direction Q (cf. Fig. 1 ), which is oriented parallel to the side surfaces 13, 15 and transversely to the longitudinal direction L and thus corresponds to the orientation of the named axis of rotation D, has the same position that is defined by the distance from the first narrow side 25. This distance is in Fig. 1 characterized by a double arrow which extends between the center line of the first receptacle 17 running parallel to the longitudinal direction L and the outwardly facing surface of the first narrow side 25. The second receptacle 19 and the fourth receptacle 23 also have a matching distance from the narrow side 25, which is shown in FIG Fig. 2 is characterized by a double arrow which extends between the center line of the second receptacle 19, which runs parallel to the longitudinal direction L, and the outwardly facing surface of the first narrow side 25. The center lines mentioned each simultaneously represent a line of symmetry of the respective receptacle 17, 19, 21, 23.

As is particularly evident from the different lengths of the double arrows in FIGS. 1 and 2 becomes clear, the first receptacle 17 and the third receptacle 21 have a different distance from the narrow side 25 than the second receptacle 19 and the fourth receptacle 23, so that the first receptacle 17 and the third receptacle 21 on the one hand and the second receptacle 19 and the fourth receptacle 23, on the other hand, are arranged offset to one another in said transverse direction Q. The offset is about 4 mm. In this way, depending on the assembly orientation of the locking part 11, one or more receptacles 17, 19, 21, 23 can be provided in two different positions for the engagement of a locking pin.

In all the embodiments shown, the closing part 11 has a plurality of holes 29, 31, 33 which are formed in the first side surface 13 and in the second side surface 15, respectively. The arrangement and the type of the holes 29, 31, 33 in the first side surface 13 correspond to the arrangement or the type of the holes 29, 31, 33 in the second side surface 15 first side surface 13 and a corresponding hole 29, 31, 33 provided at a corresponding point of the second side surface 15 through channels which extend perpendicular to the side surfaces 13, 15 through the closing part.

In the two side surfaces 13, 15 each have two holes 29, 31, 33, which are arranged closer to the first narrow side 25 with respect to their respective center point than the receptacles 17, 19, 21, 23, adjustment holes 29 through which through screws can be screwed into the frame of the respective window or the respective door, in particular into a groove formed in the frame. Because two spaced apart screws engage in a groove in this way, the closing part 11 can be positioned with its longitudinal direction L precisely parallel to the groove of the frame.

In each case three further holes 29, 31, 33, which are arranged further away from the first narrow side 25 in relation to their respective center point than the receptacles 17, 19, 21, 23, represent fixing holes 31 through which further screws or other fastening means can penetrate to attach the locking part to a differently profiled area of the frame profile in different frame profiles. The fixing holes 31 each have a larger diameter than the adjustment holes 29, one of the three fixing holes 31, namely the middle one in the longitudinal direction L, having a larger diameter than the other two. As a result, the central fixing hole 31 is particularly suitable for receiving an inclined anchor, which may be anchored in the frame profile by means of mortar. To countersink the screws or other fastening means, the adjustment holes 29 and the fixing holes 31 are each widened conically at their outwardly pointing edges.

Two further holes 29, 31, 33 each formed in the two side surfaces 13, 15, which are arranged further away from the first narrow side 25 in relation to their respective center point than the receptacles 17, 19, 21, 23, represent spacer holes 33, which are designed as threaded holes in the embodiment shown. These spacer holes 33 are not conically widened and each have a thread, in particular a fine thread, so that a total of two continuous threaded channels are formed through a spacer hole 33 of the first side surface 13 and a spacer hole 33 of the second side surface, into which threaded pins can be screwed . These threaded pins can then function as variable spacers around the closing part 11, which rests in the area of the first narrow side 25 preferably directly on the mentioned groove of the frame, on the other side of the receptacles 17, 19, 21, 23, in particular in the area of the second Narrow side 27 to be able to support the frame profile largely independently of its specific structure. In principle, however, other spacers can also be used be used in some other way with spacer holes 33 so that spacer holes 33 may not need to be threaded depending on the type of spacer.

In the case of the Figs. 1 and 2 The first embodiment shown, the closing part 11 is formed from a sheet metal which was brought into the circumferentially closed tubular shape shown by bending over at three edges. As a result of the bending over, a first side edge 35 and a second side edge 37, which is opposite to it in the circumferential direction, meet one another along a seam of the tubular shape that is thereby formed. If the sheet metal were still flat, the two side edges 35, 37 would point transversely to the longitudinal direction L in opposite directions. In the first embodiment shown, the seam runs in the area of the corner between the first side surface 13 and the second narrow side 29. In principle, however, the seam can also be located at another point, preferably in the area of a corner of the cross section of the closing part 11.

So that the closing part 11 cannot be bent open, the first side edge 35 and the second side edge 37 must be firmly connected to one another. For this purpose, they can be welded to one another, for example. In the first embodiment, the connection is not made by welding, but by the interaction of a tab 39 formed on the first side edge 35 with a tab receptacle 41 formed on the second side edge 37 The trunk of the T-shape is bent around the corner at which the two side edges 35, 37 meet, with the spar of the T-shape into the tab receptacle 41 in a form-fitting manner. Since the ends of the spar of the T-shape, which extend parallel to the longitudinal direction L, engage behind the edges of the tab receptacle 41, the tab 39 can only be in the radial direction with respect to the tubular shape of the closing part 11 (due to the position of the tab receptacle 41 in the second narrow side 27, in the embodiment shown, this radial direction corresponds to the transverse direction Q) mentioned in FIG Tab receptacle 41 or from the tab receptacle 41 are moved, but not in the circumferential direction. As a result, the first side edge 35 and the second side edge 37 are reliably attached to one another. Such a design enables the closing part 11 to be largely manufactured in a progressive assembly in which the sheet metal can be cut and / or punched and bent over by means of a progressive assembly tool.

the Fig. 3 shows an alternative second embodiment in which the closing part 11 is formed from a hollow rectangular profile, that is to say a tubular profile that is closed around the circumference and has a rectangular cross section. The rectangular profile is preferably seamless, so that, unlike in the first embodiment, it is not necessary to firmly connect two side edges to one another. Therefore, the closing part 11 of the second embodiment also has neither a tab nor a tab receptacle or other fastening means for bridging a seam. Otherwise, the closing part 11 largely corresponds to the first embodiment. The corners of the rectangular shape are rounded in a corresponding manner as in the case of the bent sheet metal of the closing part 11 of the first embodiment. In principle, however, the radius of curvature can also be different from what is shown, in particular smaller. In addition, individual or all corners can also not be rounded.

In the Fig. 4 The third embodiment shown of a closing part 11 according to the invention corresponds again to the first embodiment with regard to the design of the tubular shape as a bent sheet metal. In principle, however, like the second embodiment, this embodiment could also be formed from a circumferentially closed tubular profile. Furthermore, in the third embodiment, as in the first and the second embodiment, adjustment holes 29, fixing holes 31 and spacer holes 33 with a corresponding function are provided, which however have a different position along the longitudinal direction L in the third embodiment. The third embodiment also differs of the first and the second embodiment mainly by the way in which, in particular in which direction, the receptacles 17, 19, 21, 23 extend into the first side surface 13 and into the second side surface 15, respectively. This is because the first receptacle 17 and the third receptacle 21 or the second receptacle 19 and the fourth receptacle 23 do not extend from their respective open ends towards one another as in the first embodiment and in the second embodiment, but away from one another into the respective side surface 13, 15.

For this purpose, a central transverse recess 43 is provided on the closing part 11, which extends in the transverse direction Q from the first narrow side 25 into both the first side surface 13 and into the second side surface 15. In the first side surface 13, the transverse recess 43 extends up to between the first receptacle 17 and the third receptacle 21, and in the second side surface 15 the transverse recess 43 extends up to between the second receptacle 19 and the fourth receptacle 23, so that the recesses 17, 19, 21, 23 each open with their open end into the transverse recess 43. This connects the transverse recess 43 and the two receptacles 17, 19, 21, 23 of the respective side surface 13, 15 to form a T-shaped free space, the spar of the T-shape in the first side surface 13 and the spar of the T-shape are arranged offset to one another in the transverse direction Q in the second side face 15 (cf. the in Fig. 4 contours of the second receptacle 19 and the fourth receptacle 23 shown in dotted lines, which are almost completely covered by the first side surface 13 at the viewing angle shown).

In the case of a closing part 11 according to the in Fig. 4 The third embodiment shown can be an associated locking pin, for example when closing the sash of the respective window or the respective door through the transverse recess 43 in the transverse direction Q in the area between the two recesses 17, 19, 21, 23 of the side surface 13 facing away from the frame , 15 arrive. Through Adjusting the fitting arrangement on which the locking pin is provided, the locking pin can then, depending on the direction of movement, either engage in one or the other of these two receptacles. In this way, a single locking part 11 can be used in order to provide two receptacles for securing the locking pin in two locking positions which are opposite with respect to the longitudinal direction L.

Because the first receptacle 17 and the third receptacle 19 are also offset in the transverse direction Q with respect to the second receptacle 19 and the fourth receptacle 23 in this third embodiment, receptacles 17, 19, 21, 23 for the engagement of a locking pin, in particular a mushroom head pin, are provided in two different positions, which correspond to different groove center positions of the respective window or the respective door.
