Description

DESCRIPTION

Security hardware part as well as hardware layout and frame and sash layout

The invention relates to the technical field of frame and sash arrangements that are equipped with an opening limitation function. An opening limitation function results in a limitation of the opening angle of a window or door sash.

The regulatory requirements for so-called opening limiters or opening limiting installations are specified in particular in DIN EN 13126-5 (status October 2019).

A distinction can be made between "simple" opening restrictors for sash fixing, for example for ventilation purposes, and those with requirements for child safety. With "childproof" opening limiters the maximum opening of 89 mm should not be exceeded. Opening limiters with requirements for child safety are regulated in particular in DIN EN 16281 (status October 2019).

As an opening limiter, scissors can be used as a functional element. A functional scissor (scissor arm) can thus limit and/or maintain the opening angle in a rotating and/or tilting position of the leaf. The scissor or scissor arm can be configured as a frame side hardware part and interact with the sash side hardware arrangement. Furthermore, a scissor can be used respectively in the upper and lower frame area, in particular in the case of casement windows.

The window or door leaf can rotate about a vertical axis and/or tilt about a horizontal axis. The opening limitation facility may alternatively or additionally also be referred to as a deployment device.

Finally, the frame and sash arrangement can be configured by means of a hardware arrangement in such a way that unlocking and locking of the sash are made possible. In this case, a drive device, such as a window handle or a door handle, can be provided to drive the fitting and/or the frame and/or sash arrangement.

The maximum opening width limited by the scissors or the scissors arm can be, for example, 89, 100 and/or 120 mm.

Via the drive device, in particular via the door handle or the window handle, the sash can also be brought into a release position in the state of the art, generally releasable by means of a lock, in the that the sash can be pivoted in relation to the frame without an opening limitation.

In the sash release position, the scissor, in particular the scissor arm, is arranged in the frame or in a recessed slot in the frame. In the release position, that is, with the leaf pivoted open, an unwanted manipulation of the scissor arm can occur without major problem, consciously or also involuntarily, and the scissor arm can be pivoted outwards, very easily, in case from mishandling, for example, towards the outside of the frame and/or the recessed slot in the frame. This can cause the scissor arm to be mechanically stressed and, in particular, to break.

The manipulation can also have the consequence that the sash can no longer be closed. In this way, it is possible to avoid a shifting of the leaf from the unlocked position to the open limit position and/or to the closed position.

Such manipulation can take place intentionally or unintentionally, in particular during cleaning work. A desired manipulation can be carried out by intruders to damage the window or the door.

Ultimately, incorrect handling can lead to the sash no longer being able to close properly. For example, after several years of operation, the scissor arm can only be insufficiently held in the recessed slot in the frame in the sash release position.

In the case of the known sash opening limitation, this conditions complicated handling.

Document EP 3045635 A1 refers to a device for helping and facilitating the opening and closing of a window or door leaf with at least one spring installation acting between a frame and the window or door leaf to help open and close, which is operatively connected with a deployment scissor.

DE 2426030 A1 relates to a window, a trim frame and a sash frame that can be pivoted and tilted with respect to it, which is fixed to the trim frame by means of a rotating cladding system arranged along a vertical side of the window and by means of a tilting hardware system arranged along a lower side of the window.

DE 20 2012 002 502 U1 relates to a combined acceleration and deceleration device for a window or door sash with a transmission rod fitting that can be driven through a fitting slot and a recess, including a scissor extendable, whose opening width can be limited by one inclined position by means of a pivoting arm pivotally articulated on one side on the frame and on the other side on the sash.

The object of the present invention is now to avoid or at least substantially reduce the aforementioned disadvantages of the state of the art.

The above-mentioned object is achieved according to the invention by a security hardware part that is intended to be arranged in or on a recessed groove of a window or door frame, the security hardware part having a base body and a stop means provided for the base body, for fixing in the recessed groove, securing means being provided on the base body for fixing and/or locking a scissor arm housed in the frame in a release position of a window or door sash, an elongated guide for the stop means being provided on the base body and the base body being displaceable along the guide relative to the stop means.

The aforementioned window and the aforementioned door each have at least one leaf. The invention can be provided for any type of sash opening, in particular parallel extension sashes, drop-fold sashes, tilt sashes, folding sashes, rotating sashes, compound rotating sashes, vertical sliding sashes and drop-fold sashes. of skylight Particular preference is given to the use in windows or doors with a turning and/or tilting function.

According to the invention, the safety hardware part allows the scissor arm, which may be provided in particular to limit the opening of the sash, to be secured and/or blocked better than in the state of the art. A securing and/or locking of the scissor arm can take place, preferably exclusively, in a release position of the window or door sash. A sash release position may be present at least when the sash can be rotated open without the opening restriction, ie without the scissor arm hinged on the sash.

The security hardware part can be placed in a recessed slot in the frame, in particular pivoted inwards and/or inserted. In this connection, it can be provided that in the intended "use state" of the security hardware part, provision is made for the base body to be able to move in the recessed groove, at least within certain limits. In contrast, the stop means can be arranged stationary in the recessed groove, preferably C-shaped. In particular, the stop means can be configured such that the longitudinal displacement capacity of the base body in the recessed groove is limited in the state of use.

The safety hardware part can enable incorrect handling and/or manipulation of the scissor arm to be prevented or at least hindered. This results from the fact that by means of the safety hardware part according to the invention a securing or blocking of the scissor arm can take place due to the securing means interacting with the scissor arm in any case when the scissor arm is not engaged. on the sash or on the sash hardware.

In particular, the free end of the scissor arm can be secured by the securing means of the safety hardware part according to the invention. The free end of the scissor arm can be hooked in the sash opening limitation position, in the sash fitting, thus finally allowing the opening limitation. Furthermore, the free end of the scissor arm can be arranged on the front side housed in the frame and/or end zone and/or front side and/or end zone opposite the scissor arm.

The safety hardware part according to the invention can preferably be coupled with a frame and sash arrangement known in the state of the art to limit the opening of the sash, a scissor arm being provided to limit the opening. Thus, in particular, retrofitting with the safety hardware part according to the invention can take place. This makes it possible for the scissor arm to be retrofitted with existing windows or doors.

In this way, for example, incorrect handling when cleaning the window, in which case the sash is usually in a release position, can be avoided. Ultimately, the scissor arm cannot easily and/or non-destructively pivot and/or move out of the frame due to the securing through the security hardware.

According to the invention, the possibility may arise that due to the mobility or displaceability of the base body in relation to the stop means, the safety hardware part can engage with and disengage from the scissor arm. In particular, the security hardware part does not affect either the opening limitation position or the closing position of the sash.

In this context it is understood that a change of the respective sash positions can occur via the actuating device, ie, for example, the window handle and/or the door handle. The safety hardware part can also be adjusted at least indirectly in the state of use via the drive device. In particular, the base body can be brought indirectly into different (holding) positions with respect to the stop means, a change of these positions being possible via the drive device.

According to the invention, it can thus be made possible that the safety hardware part according to the invention can be driven indirectly via the frame and sash arrangement and/or indirectly via the drive device.

The safety hardware part according to the invention allows a plurality of advantages, as already described. The versatility of use of the security hardware part is also considerable in this respect. Thus, the security hardware part can finally be used, in particular, on each window or each door, which allows an opening restriction by means of at least one scissor arm. The scissor arm can be secured and/or locked in particular in various ways by means of the securing means.

Thus, for example, the scissor arm can be surrounded at least in sections on at least one longitudinal side by the securing means.

Particularly preferably, the scissor arm is fixed at the free front end of the scissor arm that is not supported in an articulated manner.

Therefore, the safety hardware part can be arranged, in its state of use, in the recessed slot of the frame at a distance from the scissor arm housing, in particular it can be the distance between the outer end of the hardware part security hardware, which is directed towards the scissor arm housing, and the scissor arm housing, greater than or equal to the length of the scissor arm.

According to the invention, the advantageous properties of an opening restriction can thus be exploited, while at the same time no longer having to be feared that incorrect handling and/or tampering with the opening restriction device, in particular the scissor arm In particular, this also enables a longer service life of the entire frame and sash arrangement, since the frame and/or sash arrangement no longer has to be replaced and/or repaired due to incorrect handling and/or handling of the material. scissor arm This reduces running costs for maintenance or care of the window or door.

The security hardware part can preferably be configured in such a way that it interacts with a (predeterminable) recessed groove in the frame and/or is configured in correspondence with a (predeterminable) recessed groove in the frame. In this context, it is clear in particular that the security hardware part is designed as a frame-side hardware part.

In this case, however, the frame-side security hardware part can interact in particular with other sash-side hardware parts or with the sash hardware.

It goes without saying that, according to the invention, the arrangement of the stop means for fixing in the recessed groove is to be understood in such a way that the stop means can be connected with the recessed groove of the frame in its state of use. In this context, provision can be made for the stop means to be at least essentially completely fixed in the recessed groove.

In a further preferred embodiment, it can be provided that the stop means is only partially fixed in the recessed groove of the frame and/or does not have to be arranged exclusively in the preferably C-shaped recessed groove of the frame.

In the present case, a recessed groove is also understood to mean an at least essentially smooth recessed surface on the frame, which may even be groove-free. This is especially the case in the wood and plastic area of windows or doors. Then the stop means and the base body would be configured according to the respective recessed surface and, in particular, for connection with the recessed surface or the recessed groove.

In a particularly preferred embodiment, provision is made for the base body to have an elongated shape. An elongated shape of the base body means that the length of the base body is greater than the width of the base body. In particular, the base body can be inserted into the recessed slot of the frame with its longitudinal extension in the longitudinal direction of the recessed slot. In this case, the width of the base body can be designed in particular as a function of the width of the undercut slot and/or the width of the free opening of the undercut slot, such that at least the upper part of the base body protrudes of the recessed slot. Thus, the base body can be inserted into the undercut groove by means of appropriate clamping means on the underside in the undercut groove by clamping or pressing in. The maximum width of the base body is preferably greater than or equal to the free opening width of the recessed groove, which is specified in particular by the free distance between the groove arms of the recessed groove.

The securing means can preferably be arranged on the front side of the basic body. It is particularly preferably provided, in the state of use of the safety hardware part, that the front end of the base body, which has the securing means, faces the scissor arm.

In alternative embodiments, provision can also be made for the securing means to be provided on at least one longitudinal side of the base body and to form, for example, a C-shaped receptacle for the scissor arm.

An arrangement of the securing means on the front side on the base body is particularly advantageous in that it can lead to a stable and/or permanent securing of the scissor arm. In this way, for example, at least one section of the end of the front side of the scissor arm, in particular a protruding projection, can be housed in the securing means on the front side of the base body, which can make it difficult to manipulate the arm. scissor arm

In a further preferred embodiment, it can be provided that the securing means can be locked with the scissor arm. Alternatively or additionally, it can be provided that the securing means can be positively and/or frictionally connected to the scissor arm. Ultimately, incorrect handling of the scissor arm can be prevented by the previously mentioned configuration of the securing means. In this way the securing means can be locked in particular with the free end of the scissor arm in a position for releasing the blade. By the preferably positive-fitting arrangement between the securing means and the scissor arm, it can be made possible that the scissor arm cannot be swiveled out of the frame without applying great forces and/or deliberately "pulling" on the safety hardware part. .

The securing means can be configured in particular depending on the respective scissor arm, which is to be secured via the securing means and finally via the safety hardware part. The shape of the securing means corresponding to the section of the scissor arm that can be connected to the securing means may allow a positive and/or frictional connection between the securing means and the section of the scissor arm in question.

Preferably, the securing means can be configured as a clamping element which has an open-end receiving opening with at least one elastic clamping arm. Ultimately, a snag on the securing means can occur via an outwardly opening snag opening, which can be seen as part of the opening side of the receiving opening and/or leading into the receiving opening. accommodation. The latch opening ultimately serves to receive the scissor arm.

Ultimately, the securing means can be configured as a hooking means for gripping the scissor arm, in particular the free end of the scissor arm. The securing means for its part can alternatively or additionally also be configured as a flat fork which can form a C-shaped receiving opening.

In addition, the securing means can also have elastic properties, so that the scissor arm can catch and/or "hook" in the securing means.

In this case, the securing means can extend at least substantially over the entire height of the base body or only over a section of the height. Thus, for example, the securing means can be arranged in the upper region of the base body, in particular on the upper side opposite the guide. The height of the securing means can be from 1% to 60%, preferably from 5% to 25%, of the height of the base body.

Furthermore, the securing means can be elastically and/or elastically flexible, the elasticity being able to be ensured in particular by the clamping arm. In this context, it is understood that the securing means also has two clamping arms and can be configured as a fork, in particular flat. The securing means can in particular have at least one clamping arm, preferably U-shaped and/or C-shaped.

In a further preferred embodiment, provision is made for the receiving opening, in particular the latching opening, to be open in the longitudinal direction of the base body away from the base body. In the state of use, the receiving opening, in particular the opening for engaging the receiving opening, can be directed towards the scissor arm, preferably towards the free end of the scissor arm.

Such an arrangement of the receiving opening and, ultimately, of the securing means in the base body makes it possible for the scissor arm to be hooked through the base body by means of the securing means in order to secure and /or lock in the state of use of the security hardware part.

Furthermore, in a further preferred embodiment it is provided that the receiving opening is designed to receive a projection of the scissor arm, in particular designed as a head rivet. In this case, the latching opening can have an opening width less than or equal to the outside diameter of the projection of the scissor arm. Insertion of the projection of the scissor arm into the receiving opening can then be made possible by the fact that the securing means and in particular the elastic clamping arm of the securing means have spring and/or elastic properties. As a result, during the hooking process of the scissor arm projection in the receiving opening of the securing means, a widening of the hooking opening and subsequent hooking of the projection can occur.

The receiving opening can be configured in particular in correspondence with the projection of the scissor arm, it being possible for the internal diameter of the receiving opening to be less than or equal to the external diameter of the projection of the scissor arm. scissor arm Such a configuration of the receiving opening and thus also of the securing means is advantageous, since the projection of the scissor arm is already known and is present in the prior art. The scissor arm projection known in the prior art, which can be arranged at the free end of the scissor arm, is generally configured as a head rivet. In this connection, the head region of the projection, which is preferably configured as a head rivet, can protrude in particular from the securing element and preferably from the elastic clamping arm, so that it can be easily grasped and held.

Finally, in a particularly preferred embodiment, provision can be made for at least one section of the scissor arm projection to be arranged in the receiving opening of the securing means in order to secure and/or block the scissor arm. In particular, the upper and/or lower area of the scissor arm projection can be arranged outside the securing means. In the secured state of the scissor arm, the protrusion of the scissor arm can be surrounded by the securing means at least in sections, the protrusion thus being able to hook into the securing means and preferably be held in a latching manner.

The projection of the scissor arm can in particular be retracted through the securing means, preferably in the blade release position.

The projection of the scissor arm can additionally be designed so that it can be displaceably arranged on the sash fitting, preferably in a latching opening of the sash fitting, in the sash opening limiting position. Lastly, the projection of the scissor arm can engage in a corresponding guide/hook opening, preferably in a corresponding guide groove, of the sash fitting. The guide/hook opening of the sash fitting can have an insertion opening for hooking and inserting the projection. Furthermore, the projection of the scissor arm can also be locked and/or secured in the sash fitting and/or come into contact with a corresponding stop on the sash fitting. This is used in particular to specify the maximum opening angle or the maximum opening width. The projection of the scissor arm can preferably also catch on the sash fitting when the maximum opening width is reached. Furthermore, the projection can be configured in correspondence with the hook opening of the sash fitting.

By means of the securing according to the invention, the projection can finally be fixed on the frame side in the sash release position.

In an additional and very particularly preferred embodiment of the inventive concept, provision is made for the base body to have, on its upper side remote from the stop means and/or on its upper side remote from the guide for the stop means, a hooking section to interact with a corresponding sash side driver section of the hardware arrangement in the sash closed position. The hooking section can be designed in particular in such a way that the carrier section can hook into the hooking section and/or both sections can interact with each other, in particular for longitudinal displacement of the base body. In this context, it is understood that either the coupling section can be configured as a recess and the driver section as an elevation, or vice versa.

In addition, the hooking section and/or the drive section can have a corresponding hooking opening, preferably on the longitudinal side, for receiving the respective corresponding and/or complementary section. The above-mentioned design of the base body allows an adjustment of the security hardware part or of the base body in the state of use of the security hardware part via a sash-side hardware part. Through the coupling section, it can thus be ensured that no further frame-side hardware parts, such as push rods or the like, are required for the displaceable arrangement of the base body on the frame side. In this way, the sash fitting can be used to allow the base body to be displaced relative to the stop means. Finally, the security hardware part is moved in the closed state of the sash by actuation of the drive device, and specifically in correspondence with the selected position of the drive device. If the drive installation is in the release position, the securing means engages the projection of the scissor arm and secures it. The stop means here in particular limits the displacement of the base body along the recessed groove.

Consequently, the security hardware part can be brought into the respective desired (locking) position, in particular separated from other frame-side hardware parts, by means of sash-side hardware parts or by means of the sash hardware. An interaction between the driver section and the hooking section is provided, in particular, exclusively in the closed position of the leaf. In this case, the driver section can be displaced or adjusted by the drive device, which in turn can lead to a displacement of the base body of the safety hardware part, in particular when the driver section and the lock section hitch can interact with each other.

In another very particularly preferred embodiment, provision is made for the latching section to be designed as a cavity. The hook section can alternatively or additionally be accessible from the upper side and from at least one longitudinal side of the base body. The hitch section, in the state of use, is preferably configured in such a way that it is open at least in some areas on the longitudinal side facing the sash and thus provides a hooking opening for the driver section.

Very particularly preferably, the hook section is open on both longitudinal sides of the base body and/or the hook section is accessible from both longitudinal sides of the base body. Such a configuration is advantageous in that the base body can be used both for the arrangement provided on the top side of the frame as well as for the arrangement provided on the bottom side, as well as for left and right-joined sashes. Ultimately, the same base body can then be used for both the upper frame fitting and the lower frame fitting, regardless of the type of sash fitting.

An accessibility to the hooking section of the base body from a longitudinal side allows in particular that the driver section can ultimately pivot or hook into the hooking section when the sash is closed. In the closed position of the window, a drive via the drive device can then lead to the displacement of the driver section and thus indirectly also to the displacement of the latching section.

The driver section and the hook section can be arranged in the closed position of the sash in such a way that the driver section is arranged at least essentially free of play in the hook section. Therefore, an at least essentially precise adjustment coordination of the driver section and the coupling section can take place. In addition, in an alternative embodiment, a clearance can also be provided between the driver section and the hooking section in the closed position of the sash, which is overcome in particular when the drive device is actuated and thus initiated an offset of the drag section. When the drive device is actuated, the driver section can overcome the play in relation to the stop of the coupling section and thus lead to displacement of the basic body.

In addition, in a preferred embodiment of the present invention it is provided that the stop means has arms in its lower area that project laterally to surround from below and/or from behind slot arms of the recessed slot, preferably C-shaped The lower region of the stop means can be directed towards the recessed groove and away from the base body in the state of use. In this connection, it can be provided that two laterally protruding arms are provided on the stop means on the longitudinal sides. In the inserted state of the stop means, the protruding arms can catch behind or below the groove arms of the recessed groove.

In addition, provision can be made for the protruding arms of the stop means to abut in the fixed state of the stop means in the recessed groove directly with the groove arms of the recessed groove. Furthermore, the maximum length of the stop means is greater in the region of the arms than the width of the undercut groove at the bottom of the undercut groove. The stop means thus cannot be arbitrarily rotated in the recessed groove.

Due to the protruding arms, provision can be made for the spacer to have a larger extension in the longitudinal direction than in the transverse direction. This, in particular, allows the stop means to be positioned in the recessed slot and to engage below the slot arms of the recessed slot. Thus, for example, the transverse extension of the stop means can be less than or equal to the free opening width of the undercut groove. In particular, the longitudinal extension can be greater than the free opening width of the undercut groove. In this way it is made possible in particular that the projecting arms, which can indicate the longitudinal extension of the stop means, can surround the groove arms of the undercut groove from behind in the fixed state of the stop means in the undercut groove.

In a further embodiment, the stop means can also be configured as a flat plate and/or as a flat hardware part which can be inserted into the recess surface (designed as a flat recessed groove) and/or the recessed groove of the frame. and be arranged in it, and specifically in the state of use of the security hardware piece. In this embodiment, provision can be made for the base body to be able to encircle the stop means, the latching being able to be ensured around the stop means via the guide of the base body. The base body can then be displaced relative to the stop means designed as a flat component, in particular a flat plate, and preferably engage with or on the stop means. The stop means preferably has at least two locking arms, which are configured in correspondence with the stop means configured as a flat plate and/or as a flat component. In this case, the locking arms can surround the stop means, so that the guiding of the base body can be made possible by means of the locking arms.

Furthermore, for example, the stop means can first be inserted transversely into the undercut groove and then fixed in the undercut groove by turning, for example by means of a screwdriver.

In the fixed state of the stop means in the recessed groove, the protruding arms can be designed in particular in such a way that the stop means cannot fall out of the recessed groove or cannot be removed from the recessed groove transversely to the direction longitudinal of the undercut groove.

In a particularly preferred embodiment, provision is made for a threaded connection to be provided for fixing the stop means. The base body can have a stop for interacting with the stop means during screwing in or a corresponding stop can be provided on the base body. Finally, by means of the threaded connection, a fastening of the protruding arms of the stop means to the groove arms of the undercut groove can be made possible, the stop of the base body being able to allow the stop means to be fastened in the undercut groove and thus the fixation.

The screw connection of the stop means can have, in particular, a set screw and/or a screw that can be screwed into an internal thread preferably provided centrally in the stop means. In the inserted state, it can be provided that the screw is pressed against the bottom of the recessed slot and thus holds the stop means in the recessed slot.

In addition, the stop means can have a base body, which can be designed as a sliding nut. The screw, in particular configured as a set screw, can be inserted into the internal thread of the sliding nut. The sliding nut can, in turn, have arms that protrude from its longitudinal sides.

Preferably, an access opening accessible from the top is provided in the base body, which is preferably configured as a passage for the screw, preferably the set screw, of the threaded connection. The screw, in turn, can be provided for screwing into the internal thread of the stop means.

The internal thread can be arranged on the base body, preferably the sliding nut, of the stop means. Via the internal thread, the threaded connection can interact with the base body of the stop means. Preferably, a rotation of the stop means in the undercut groove can be achieved via the threaded connection in such a way that the arms of the stop means can encircle behind and/or below the groove arms of the undercut groove. Thus, the stop means can be hooked and/or held in the recessed groove.

The screw is preferably provided in the threaded area and/or the internal thread at least in some areas with a coating in order to increase the frictional engagement. The coating may initially allow the screw to be rotated, in particular using a tool, for example a screwdriver, the abutment means inserted in the recess slot being rotated to such an extent that the arms of the abutment means surround the arms of the slot from behind. the recessed slot. Since the length of the arm is greater in total than the width of the undercut groove in the lower area of the undercut groove, the arms collide with the undercut groove walls upon slight rotation. As the screw continues to be turned, it is then screwed into the internal thread, overcoming/peeling off the coating, until the stop means grips in the groove arms. Ultimately, this serves to simplify mounting of the stop means in the recessed slot.

In addition, a guide element, preferably cylindrical hollow, can be provided to interact with the guide in the base body, preferably on the upper side in the stop means. On the inside, the guide element can have the internal thread for the screw of the threaded connection.

The guide element, which is preferably configured as a sleeve, can be arranged in such a way that the arms of the stop means are at a height of the guide element and protrude to the side. In particular, the internal thread can be provided on the inside of the guide element.

Furthermore, in a further embodiment of the invention, the guide of the base body is configured as a groove and the guide element as a sleeve projecting into the groove and/or as a body projecting into the groove. slot. Preferably, the groove width of the base body guide is at least in some areas smaller than the outer dimensions of the sleeve. The aforementioned relationship allows in particular a frictional connection between the base body and the stop means, in particular the guide element of the stop means.

Due to the flexible and/or elastic configuration of the base body, the guide element can enter the groove of the base body (ie in the guide of the base body) and be displaceable by friction.

The frictional coupling between guide and stop means allows in particular that a predetermined positioning or fixing of the base body can take place, in which case the base body can be adjusted relative to the stop means, in particular through the blade side carrier section. Finally, in order to adjust the base body, the frictional coupling between guide element and guide should first be overcome, which can be done, for example, by moving the driver section.

The width of the groove at the groove ends of the guide and/or at a central position in the middle of the groove between the groove ends may be greater than or equal to the outer dimensions of the sleeve or guide element, preferably to specify lock positions. In these positions, the frictional coupling between guide element and guide can finally be annulled. In order to leave such a position, which is defined by the aforementioned relationships, the otherwise existing frictional coupling must first be overcome. This can be done by actuating the drag section.

The enlarged width at the two groove ends and/or in the central position can in particular allow at least two, preferably three, locking positions of the base body. A locked position of the base body can occur when the guide element engages in a section of the guide, in which the groove width of the guide is greater than or equal to the outer dimensions of the sleeve.

Such a zone can be limited by at least one additional zone, in which the groove width of the guide is less than or equal to the outer dimensions of the sleeve, which ultimately causes a frictional connection. In order to result in a holding position, the otherwise existing frictional engagement would have to be overcome, as explained above. This cannot take place without the application of an external force, which can ultimately hinder incorrect handling and/or inadvertent manipulation of the arrangement of the base body in the inserted state in the recessed slot of the frame.

One of the locking positions is particularly preferably selected in such a way that the securing means can catch the projection of the scissor arm. In the at least two additional locking positions, provision can be made for the securing means to be uncoupled from the scissor arm, in particular from the scissor arm projection.

In a further preferred embodiment, it is provided that the groove or the guide configured as a groove extends, at least in some areas, from the bottom side of the base body to the top side of the base body. Finally, a passage can be provided in this way, in particular between the hooking section and the guide. The passage allows in particular a certain flexibility of the base body and/or a simple insertion of the base body into the recessed groove, in particular the passage or the groove being designed to be manually pressed and/or compressed.

Preferably, at least one fastening means, in particular configured as a retaining connection, is provided on the base body for fastening the base body in the recessed groove. The fixing means of the base body can be configured in particular in such a way that the base body can be displaced in the longitudinal direction of the recessed groove in the state of use. In this connection, the fastening means can additionally be designed in such a way that a removal of the inserted base body in the recessed groove is prevented, ultimately without manipulating the base body and/or without pressing the base body, transversely to the longitudinal direction of the undercut groove, ie towards the outside of the undercut groove, and a displacement of the base body in the longitudinal direction of the groove is permitted. In this way, the degrees of freedom of the movement of the base body can be limited by the fastening means in the state of use, while the movement of the base body in the longitudinal direction of the recessed groove can still be guaranteed. Therefore, the base body cannot be easily dropped or pulled out of the recessed groove in the inserted state. However, the fastening means is designed in such a way that a longitudinal displacement of the base body in the state of use, in particular with respect to the stop means, can be ensured. The longitudinal displacement or the longitudinal displacement capacity of the base body can be limited by the stop means.

In a further preferred embodiment of the present invention, at least two protruding retaining arms are provided on the base body on opposite longitudinal sides, in particular to surround behind and/or surround below the groove arms of the recessed groove. In particular, two retaining arms are arranged in one end region of the base body and/or in the other end region of the base body. One of the end regions of the base body can face the scissor arm in the state of use of the safety hardware part. The other end region of the base body can be arranged at the remote end of the scissor arm. In addition, the securing means can also be arranged in one of the end regions of the base body. The retaining arms can be designed in such a way that they provide a maximum width of the base body in the area of the retaining projections of the retaining arms which is greater than the free opening width of the recessed groove. The base body can therefore be designed in particular for easy hooking or insertion into the recessed groove. An insertion of the longitudinal side of the base body into the recessed groove can also be provided for the arrangement.

Very particularly preferably, the base body is inserted and/or hooked into the recessed groove of the frame together with the stop means. The stop means can be fixed and/or clamped in the undercut groove because the stop means can be rotated and/or adjusted in the undercut groove via the threaded connection in such a way that the stop means engages or clamped in the recessed slot.

During the arrangement of the security hardware part in the recessed groove, provision can initially be made for the stop means to be inserted into the recessed groove together with the base body. When inserted, it is necessary for the stop means to be arranged with its transverse extension, which is greater than the longitudinal extension, in the longitudinal extension of the base body and therefore in the longitudinal direction of the undercut groove. After the security hardware part has been inserted into the recessed groove, the stop means, in particular the base body of the stop means, can then be rotated and/or adjusted via the threaded connection, preferably via of the grub screw. During assembly, provision can be made for the grub screw to be arranged in the access opening of the base body. The locking means should catch the scissor arm boss during initial assembly. Accordingly, the mount specifically specifies the secured and/or locked position for securing or locking the scissor arm. After the stop means has been fixed in the recessed groove, the base body can then be adjusted relative to the stop means via the driver section. As a result you can retrofitting with the safety hardware part according to the invention can be carried out in a simple manner. Once assembly is complete, additional locking positions or locations ultimately result in the ability to travel through the blade side driver section.

In a further advantageous embodiment, provision is made for the base body to be at least partially made of plastic, in particular a thermoplastic and/or thermosetting plastic, preferably polyethylene and/or polypropylene and/or polyethylene terephthalate (PET). Such a material of the base body is advantageous in that it can enable the flexible and/or elastic properties of the base body.

Furthermore, the present invention relates to a hardware arrangement for a window having a sash and a frame with a pivoting and/or tilting function or for a door having a sash and a frame with a pivoting and/or tilting function. The fitting arrangement has a sash fitting, at least one scissor arm for limiting the opening, and at least one safety fitting part according to at least one of the embodiments described above.

With regard to preferred embodiments of the security hardware piece, to avoid unnecessary repetition, reference can be made to the previous embodiments, which apply in the same way to the hardware arrangement according to the invention, in which the safety hardware part is used.

In a very particularly preferred embodiment of the present invention, a projection for interacting with the securing means of the safety hardware piece is provided at the free end of the scissor arm. The scissor arm boss can also alternatively or additionally interact with the sash hardware. It is very particularly preferred that the projection can positively engage and/or connect with the securing means.

Furthermore, in a further embodiment, provision can be made for a driver section to be provided on the sash fitting, which interacts with the latching section of the safety fitting part.

The hardware arrangement can be adjusted and/or controlled in particular by means of a drive device, such as a window or door handle, for example. The scissor arm is mounted in particular on the frame side or in the frame side fitting. The scissor arm protrusion can catch on the sash fitting in the open limit position. In particular, the driver section can be arranged on a push rod of the sash fitting and can preferably be moved or displaced by actuation of the drive device.

The sash fitting can also allow the scissor arm projection to be hooked, which can preferably be hooked into a sash-side horizontal arm with a hooking opening, preferably designed as a slotted hole. The horizontal arm can, for example, be connected to a push rod of the sash fitting, which is preferably connected to a corner offset. The projection of the scissor arm can be movably engaged in the engagement opening of the sash fitting. Furthermore, in a blocking position of the opening restriction, it can also be provided that the projection can be hooked to the sash fitting.

Furthermore, as explained above, the scissor arm can be rotatably and/or pivotally housed by means of a scissor housing, and specifically in the frame, in which the sash is pivotally housed. In particular, a receiving clip with a receiving opening for the scissor arm can be arranged on the scissor mount, in particular the receiving clip and the scissor arm can be connected, in particular, hooked together positively and / or by friction. As a result, an additional securing of the scissor arm can take place, preferably in the blade release position, via the receiving clip.

Furthermore, the present invention relates to a window or door frame and sash arrangement with a hardware arrangement according to at least one of the embodiments described above. The window or door sash can pivot between a closed position, an opening limitation position and a release position. In the closed position, the sash is finally arranged in the frame. In the opening limit position, the opening width or opening angle of the sash is restricted, preferably by means of a scissor arm. In the sash release position, the sash can finally be pivoted without an opening restriction function. The sash fitting can be arranged in a recessed sash slot. The scissor arm, which is intended in particular to limit the opening, can be hingedly mounted on the frame and provided to interact with the sash fitting. The security hardware piece can be mounted in the recessed slot in the frame and provided to interface with the sash hardware. The safety hardware part locks and/or secures the scissor arm, preferably exclusively, in the sash release position.

In this context, it goes without saying that the aforementioned embodiments of the security hardware part according to the invention and/or the hardware arrangement according to the invention apply in the same way to the frame and sash arrangement according to the invention. In this connection, reference can be made to the above embodiments with regard to the advantages according to the invention, special configurations and preferred embodiments.

In a very particularly preferred embodiment of the present invention, provision is made for the driver section to only interact with the hooking section in the closed position of the sash. As a result, the interaction and therefore, in particular, the adjustment of the base body in the recessed groove of the frame takes place when the sash is in the closed position. In this position, the driver section can be moved at least indirectly via a drive device, in particular a door handle or a window handle. A displacement of the driver section can lead to a displacement of the base body due to interaction with the latching section of the base body. Thus, the base body can be moved into such a holding position or situation, in which the securing means in particular secures and/or blocks the projection of the scissor arm, in particular the projection being arranged at least in sections on the securing means or in the receiving opening of the securing means.

It goes without saying that according to the invention it can also be provided that the window or the door can be closed. For this purpose a removable key lock can be provided on the sash handle. In order to close the window or the door it is provided in particular that the leaf must be in the closed position. However, this does not necessarily have to be planned. In this way, a change in the fitting arrangement can also be blocked by a lock in the release position and/or in the opening limitation position.

Furthermore, it is understood that intermediate ranges and individual ranges are contained in the ranges and range limits mentioned above and are to be considered as disclosed essentially for the invention, even when these intermediate ranges and individual values are not specifically indicated.

Other characteristics, advantages and possible applications of the present invention result from the following description of exemplary embodiments by means of the drawing and from the drawing itself.

Fig. 1A shows a frame and sash arrangement 1, which is provided in the present case for a window. It is not shown that the frame and leaf arrangement 1 can be provided for a door. Consequently, it is understood that all the window-related embodiments can also be implemented in the case of a door, without explicitly referring to it. The frame and sash arrangement 1 is equipped with an opening restriction function that can be guaranteed by a scissor arm 2. The scissor arm 2 can be housed in the frame 3. In addition, the scissor arm 2 can interact with a sash fitting 4 to make the opening limitation function available. The blade 5 can be brought to different positions. In Fig. 1A, an opening limitation position is finally represented. Fig. 3A shows a release position of the sash 5, which can finally be pivoted with respect to the frame 3 without an opening restriction. Furthermore, the sash 5 can also be brought into a closed position, in which the sash 5 is finally arranged at least in some areas in the frame 3 or enters the frame 3 with its sash recess.

A change of the aforementioned positions of the sash 5 can be brought about by actuation of the drive device 6, in the illustrated embodiment, a window handle. In addition, the sash 5 can also be locked, in particular the hardware arrangement 7 of the frame/sash arrangement 1 can be locked. Such a locking device is not shown in the embodiments shown. In particular, such a locking device, usually designed as a removable key lock, can be arranged in the drive device 6.

In the illustrated embodiments, a window with a rotating function is shown. It is understood, however, that the following embodiments can also be applied in the same way to a window with a tilt function or with a pan and tilt function, as well as to a door with corresponding functions. Furthermore, the invention can also be used with all other types of sash opening already referred to. Finally, in the case of the used window or the used door, provision is made for an opening limitation function to be made available via the scissor arm 2, in any case in the opening limitation position of the sash 5. Furthermore, the sash 5 can also be brought into a release position in which the scissor arm 2 is held on the frame side and, in particular, does not catch on the sash fitting 4.

In the frame and sash arrangement 1 shown in FIG. 1A, provision is made for a security hardware part 8 to be used on the frame side. Fig. 1C finally shows a section of the security hardware part 8.

FIG. 6 shows the security hardware part 8, which is intended to be arranged in a recess 9 of the window frame 3. The window may have a swivel and/or tilt function. Fig. 3C shows a piece of security hardware 8 inserted into the recessed slot 9.

As shown in Fig. 13, the security hardware part 8 has a base body 10 and a stop means 11 provided for the base body 10. In the exemplary embodiment shown in Fig. 13, the stop means stop 11 is finally configured in several parts. The stopper means 11 is provided for fixing in the recessed groove 9. The state of the stopper means 11 fixed in the recessed groove 9 is shown in Fig. 11C.

Figs. 14A to 14D show that a securing means 12 is provided on the base body 10. The securing means 12 is in turn provided to secure and/or lock the scissor arm 2 housed in the frame 3.

In Figs. 5 and 6 a scissor arm 2 is shown secured in the securing means 12. Fig. 5 shows a bottom view of the arrangement shown in Fig. 6.

The scissor arm 2 is secured or locked in the release position of the window or door sash 5 by means of the securing means 12, as shown in Figs. 3A and 3c. Fig. 3C shows detail B of Fig. 3A. In Fig. 3A, the sash 5 is shown in the release position, with the scissor arm 2 ultimately not engaging in the sash fitting 4. The scissor arm 2 is secured in the sash release position 5 through of the securing means 12. In the embodiment shown in Fig. 3A, it is planned that a piece of safety hardware 8 is used in the upper area of the frame 3, as shown in detail A in Fig. 3B of Fig. 3A. A safety hardware part 8 is also provided on the lower side, as shown in Fig. 3C, which shows detail B in Fig. 3A. Ultimately, therefore, at least one safety hardware part 8 can be used in a frame and sash 1 arrangement. The safety hardware part 8 secures the scissor arm 2 in the sash 5 release position. on the frame side.

In Fig. 4, a sash fitting 4 is shown with a drive device 6, which is configured in correspondence with the release position according to Fig. 3A. In contrast, Figs. 5 and 6 show the arrangement of the frame-side hardware parts in a release position of the sash 5, as can be seen in Fig. 3A.

For visualization reasons or to show details, the recessed groove 9 is omitted in the illustrations that show the hardware parts individually.

Figs. 12A to 12C show that an elongated guide 13 is provided for the stop means 11 on the base body 10. The base body 10 can be displaced relative to the stop means 11 along the guide 13. In Figs. .

12A to 12C a displacement capacity of the base body 10 with respect to the stop means 11 is represented. Finally, the base body 10 is represented in Figs. 12A to 12C in three positions with respect to the stop means 11. In particular, the positions of the base body 10 shown in Figs. 12A to 12C represent locking positions that can correspond to the release position, opening limitation position and closed position of the leaf 5.

Furthermore, the relative scrollability is also depicted in Figs. 14A to 14D, as well as 15A to 15D and 16A to 16E. Figs. 14A, 15A and 16A show the non-fixed state of the security hardware part 8 or the non-fixed state of the stop means 11. The extent to which the base body 10 can move relative to the stop means 11 in the state of use, it is shown in Figs. 7A to 9B. A cross-sectional view of the hardware arrangement 7 is shown in FIG. 7A, it being shown schematically through the illustrated drive device 6 that this state of the hardware arrangement 7 ultimately prevails in the sash release position. 5. In this release position of the sash 5, the scissor arm 2 is secured through the safety hardware part 8 by means of the securing means 12, as shown in Fig. 7B. Fig. 7B shows a view top of the safety hardware part 8, as well as the scissor arm 2, which is shown in the cross-sectional view of Fig. 7A. A detailed view of the security hardware part 8 is also shown in Fig. 7A.

In Fig. 8A it is shown that the base body 10 has moved relative to the stop means 11, specifically in particular away from the scissor arm 2. The scissor arm 2 is therefore no longer engaged with the workpiece. security hardware 8, as shown in Fig. 8B. Fig. 8B is a plan view of the frame side hardware used in Fig. 8A. Fig. 8A shows a cross-sectional view of the hardware arrangement 7 in the open limit position. This is indicated schematically because the drive installation 6 is shown. In addition, the opening limit position is indicated by the fact that the scissor arm 2 hooks into the sash fitting 4 and is finally also angled, as shows Fig. 8b .

FIG. 9A shows another position of the base body 10, with the safety hardware part 8 being even further away from the scissor arm 2 than the state shown in FIG. 8A. The safety hardware part 8 is no longer engaged with the scissor arm 2. Fig. 9B shows a plan view of the frame-side hardware parts used in Fig. 9A. In Fig. 9B it is shown that the scissor arm 2 is no longer bent, which is ultimately due to the closed position of the sash 5.

The recessed groove 9 provided in the illustrated embodiments is configured as a C-shaped recessed groove with groove arms 14. It goes without saying that in other embodiments the recessed groove 9 can also be configured as a recessed surface, for example without slot arms 14. Ultimately, the recessed slot 9 serves as a base for fixing the hardware arrangement 7 to the frame 3 and to the sash 5, which instead of the realization of a base that actually has a slot also it can be configured as a flat base in the form of a flat recess surface. Despite this configuration, such a recessed surface is called a recessed groove 9 in the present case.

Fig. 13 shows that the base body 10 has an elongated shape. The elongated shape of the base body 10 results in particular from the fact that the base body 10 has a length greater than its width. The base body 10 is inserted with its longitudinal extension in the longitudinal direction of the undercut groove into the undercut groove 9, as can be seen, for example, in Fig. 3C.

The securing means 12 can be arranged on the front side of the base body 10, as shown, inter alia, in FIG. 12A. In this case, the securing means 12 can have a height corresponding to the base body 10 and/or a height that is smaller than the base body 10. Figs. 14A to 14D show that the securing means 12 has a lower height than the base body 10 and is arranged on the upper side 15 of the base body 10, which faces away from the guide 13. The height of the securing means The securing means 12 can be between 3% and 50% of the height of the base body 10. Finally, the securing means 12 protrudes from the base body 10 on the front side like an arm.

Fig. 6 shows that the securing means 12 is configured in such a way that it can be hooked onto the scissor arm 2 as well as positively and frictionally connected. In particular, the securing means 12 surrounds at least in sections a section of the scissor arm 2.

It is not shown that the securing means 12 can also be arranged on a longitudinal side of the base body 10, in particular to surround a section of the longitudinal side of the scissor arm 2.

The securing means 12 shown in Figs. 14A to 14C have a receiving opening 16 which is open at the end side. The receiving opening 16 is used to arrange or surround, at least in sections, the scissor arm 2, as shown, for example, in Fig. 6. The securing means 12 is further configured as a clamping element in Figs. 14A to 14D, which has at least one elastic clamping arm 17. In the illustrated embodiment, the clamping arm 17 has two arms. Otherwise, the receiving opening 16 and finally also the clamping arm 17 are C-shaped or U-shaped. The clamping arm 17 can have flexible and/or elastic properties. The flexible properties of the clamping arm 17 are particularly advantageous for locking and/or positive-fitting the scissor arm 2.

In FIG. 7B it is shown that the receiving opening 16 is open in the longitudinal direction of the basic body 10 opposite the base body 10. Finally, the receiving opening 16 is directed in the state of use towards the lifting arm. scissor 2 or towards the free end of scissor arm 2.

The securing means 12 can finally be configured as a flat hairpin and/or as a clip.

In Figs. 3C, 7B and 10A show that the receiving opening 16 is configured for receiving a projection 18 of the scissor arm 2. The projection 18 can in turn be configured as a head rivet. The projection 18 can also be surrounded by the securing means 12 at least in areas, as shown in Fig. 7B. In particular, a further section, for example the head section, of the projection 18 may protrude beyond the securing means 12, in the secured state of the scissor arm 2.

In order to limit the opening or to limit the opening width and the opening angle of the sash 5, the projection 18 of the scissor arm 2 can be hooked on the sash fitting 4 and, in particular, guided by the sash fitting 4 in such a way. scrollable. When the maximum opening width is reached, the projection 18 can hit a stop on the sash fitting 4 and/or jam in the sash fitting 4. A hooking of the projection 18 on the sash fitting 4 is schematically shown in Fig. 1A, as well as in the detail of Fig. 1B and in Fig. 2. The projection 18 of the scissor arm 2 can be slidably engaged in this connection, in particular in an elongated hole and/or in an opening of hook 40 of the sash fitting 4 and be guided by the sash fitting 4. In the release position of the sash 5, this projection 18 can then be locked and/or secured on the frame side by the securing means 12.

Figs. 14A to 14D show that the base body 10 has on its upper side 15 remote from the stop means 11 and/or the guide 13, a hooking section 19 to interact with a corresponding driver section 20 on the blade side in the position closed of sheet 5. In Figs. An interaction between the driver section 20 and the latch section 19 is shown in 7A, 8A and 9A. The driver section 20 is also clearly visible in Figs.

2 and 4. The driver section 20 ultimately interacts with the hook section 19 in the closed state of the sash 5, since the hook section 19 is provided on the frame side and the driver section 20 on the door side. the sheet. A latching of the driver section 20 on the latching section 19 is therefore only possible in the closed or pivoted state of the sash 5.

A relative displacement of the base body 10 with respect to the stop means 11 can therefore take place via the driver section 20. The driver section 20 can in turn be displaced by the sash fitting 4, which in particular can be driven via the drive device 6. Thus, on the frame side, the safety hardware part 8 does not necessarily have to be connected to a push rod or the like. In particular, on the frame side, the security hardware part 8 can be arranged separately from other frame-side hardware parts and finally, in particular, be inserted into the recessed groove 9 in such a way that, in the position sash release 5, the scissor arm 2 can be secured or locked on the frame side via the safety hardware part 8.

In the embodiment shown in Figs. 14A to 14D, the latching section 19 is designed as a cavity, which is accessible from the upper side and from at least one longitudinal side of the base body 10. This allows the driver section 20 to be inserted/swiveled into the interior. in the hook section 19 from the longitudinal side. This takes place when the leaf 5 is pivotally closed.

It is not shown that the latch section 19 can alternatively also be configured as a lift. Corresponding to this, the driver section 20 could be configured as a cavity.

In the illustrated embodiment, the driver section 20 is configured as a projection, in particular as a pin or the like.

The base body 10 is preferably accessible from both longitudinal sides. Such a configuration of the base body 10 is advantageous for use by the upper and lower sides of the security hardware part 8, as well as for use for leaves 5 attached to the right and left. In particular, then two different shapes of the base body 10 for upper placement on frame 3 and for lower placement on frame 3, as shown in detail in FIG. 1A, are not necessary. The planned placement on the upper side in the frame 3 is shown in detail A of Fig. 1A. The planned placement on the underside of the base body 10 is shown in detail B in FIG. 1A. Finally, a mirror-like arrangement of the base body 10 results in the recessed groove 9 in the frame 3.

Fig. 13 shows that the stop means 11 has arms 21 projecting laterally in the lower region. The arms 21 can be provided in the inserted state of the stop means 11 and, in particular, in the fixed state of the stop means 11 in the recessed groove 9 in order to encircle from below and/or to encircle behind the groove arms 14 directed towards each other, from the recessed slot 9.

In particular, the arms 21 allow the transverse extension (width) of the stop means 11 to be greater than the longitudinal extension (length). Ultimately, the extension of the stop means 11 may be greater in one direction than in the other direction. The transverse extension, by means of the arms 21, can in this respect be greater than the width of the opening 22 of the recessed groove 9. The longitudinal extension (length) of the stop means 11 can be less than or equal to the width of the free opening 22. of the recessed slot 9.

This allows the stop means 11 and thus the security hardware part 8 to be inserted when the stop means 11 is inserted into the opening width 22 with its smallest extent. This process is schematically depicted in Fig. 11A. If the stop means 11 have been inserted into the recessed groove 9, the stop means 11 can be rotated so that the arms 21 can surround the groove arms 14 of the recessed groove 9, as shown in Figs. 11B and 11C. Thus, the stop means 11 can be hooked and/or held in the recessed groove 9.

In a further embodiment, not shown, provision can be made for the stop means 11 to be configured as an at least essentially flat plate and/or a flat component, which can be arranged on a recessed surface of the frame 3 or fixed to it in another way. In this context, the base body 10 can be configured in such a way that surrounds or surrounds behind the stop means 11. In this respect, a relative displaceability of the base body 10 with respect to the stop means 11 continues to be guaranteed.

Fig. 13 schematically shows in an exploded view that a screw connection 23 is provided for fixing the stop means 11. Figs. 11B and 11C show in depicted cross-sectional views that a stop 24 is provided on the base body 10 to interact with the stop means 11 during screwing. In Figs. 11A to 11C, finally the mounting of the safety hardware part 8 in the recessed slot 9 is schematically represented.

An access opening 25 may be provided on the upper side of the base body 10. The access opening 25 is shown in particular in Figs. 14A to 14D. The access opening 25 is used to drive a screw 26 of the screwed connection 23 by means of a tool, which is inserted into the access opening 25. In the illustrated embodiments, a grub screw is provided as screw 26. screw 26 is intended to be screwed into an internal thread 27 in the stop means 11. Ultimately, the screw 26 engages in an internal thread 27 and holds in particular the stop means 11 in the recessed groove 9. The internal thread 27 can be provided in this case on the inside of a base body 28, in particular designed as a sliding nut. The base body 28 is shown in Fig. 13. The arms 21 can be arranged on the base body 28.

It is not shown that the screw 26 is provided with at least some portions of the thread region and/or the internal thread 27 in order to increase the frictional engagement. The lining can be provided for the simplified mounting of the security hardware part 8 or for the simplified fastening of the stop means 11, since when the screw 26 is actuated by a tool, the base body 28 rotates with it until the arms 21 come into contact on the inside with the recessed groove. Should the tool continue to be actuated, the liner overcomes the frictional engagement and the base body 28 is tightened and tightened.

On the upper side, a guide element 29 is provided for interaction with the guide 13 in the base body 10, in the stop means 11. The guide element 29 is arranged in particular in the base body 28, as shown in Fig. Fig. 13. An interaction between the guide 13 and the guide element 29 is shown, for example, in Figs. 16A to 16E in respective cross-sectional views. In Figs. 16A to 16D each show a side view of the security hardware part 8 as well as a cross-sectional view of the respective security hardware part 8. Fig. 16E shows a bottom view of the security hardware part. security hardware 8 shown in Fig. 16B. In the mentioned figures it can be seen that the guide element 29, preferably hollow cylindrical, engages in the guide 13. This is also shown, for example, in the detailed views of Figs. 11B and 11C.

In the bottom views of the security hardware part 8 shown in Figs. 12A to 12C, it can be seen that the guide 13 is configured as a groove. Fig. 13 shows that the guide element 29 is configured as a sleeve. In Figs. 11B and 11C show that the guide element 29 in the form of a sleeve enters the guide groove 13.

In other embodiments, provision can be made for the groove width of the guide 13 to be at least in some areas less than the outer dimensions of the guide element 29 configured as a sleeve. In this way, a frictional connection between the guide element 29 and the guide 13 can be made possible in all cases in those regions in which the groove width of the guide 13 is less than or equal to the outer dimensions of the sleeve.

Figs. 12A to 12C further show that the groove width at the groove ends is greater than or equal to the outer dimensions of the guide element 29 configured as a sleeve. Finally, Figs. 12A to 12C show a locking region 30 of the guide 13, in which the groove width is larger, specifically in particular greater than the outer dimensions of the guide element 29. Also in a central position 31, the groove width of the guide 13 is larger than the outer dimensions of the sleeve.
