The invention is directed to a locking unit comprising a lock bolt which can be arranged on a window or door wing of a window or door pivotable between a closed position and at least one open position and a wall or door frame of the window or door leaf and / or a wall adjacent thereto - or window sill portion arrangeable lock bearing, which has a receiving area in which the locking bolt for forming a locking position of the locking unit is pivoted when the locking bolt pivotally in its position of use on the window or door and the lock store adjacent thereto fixed in its position of use on the window or door frame or are fixed to the wall or window sill portion, wherein the locking bolt pivotable in its use position by means of a closing bolt bearing element at least on a circular path section, vorzugsw Rotatable iron, and is fixed laterally in the locking position swivel on the window or door.

Furthermore, the invention is directed to a window or a door with at least one associated locking unit, which arranged at a between a closed position and at least one open position pivoting window or door of the window or the door latch and one on a window or door frame of the window - Or door leaf and / or a thereto adjacent wall or window sill section arranged lock bearing, which has a receiving area in which the locking bolt to form a locking position of the locking unit is pivoted, wherein the locking bolt pivotally adjacent to the window or door leaf and the lock camp are stationary fixed to the window or door frame or on the wall or window sill section and the locking bolt by means of a locking bolt bearing element at least on a circular path portion pivotable, preferably rotatable, and be tlich in the locking position is pivotally mounted on the window or door.

The increasing number of house and apartment burglaries, which are initiated by levering windows or doors, increase the need for a fuse-technically improved, in particular a leveraging and leveraging and burglary-resistant embodiments of windows and doors.

In newer window or door sashes therefore turn-tilt fittings are installed with a so-called mushroom lock, which considerably complicates the Aushebeln thus equipped windows and doors, especially so-called French doors. Older windows or French doors with traditional fittings without such a mushroom lock are in contrast relatively easy to open with common lever tools by the fittings are levered out of the striking plates. There are therefore already retrofittable additional locks in the prior art, which are mounted on the inside of the building on a window or door leaf and the associated frame. These locking units comprise a locking bolt and a locking bearing, wherein the locking bolt engages in the locking position in the locking bearing. But such locking units have the disadvantage that they can be brought only in the closed window in the locked position or closed position. Also, it is not possible with these locking units to bring so equipped windows or doors in a tilted open position, as long as the locking unit is in its locking position.

From the DE 10 2008 047 194 A1 For example, a locking unit and a window or door wing equipped therewith are known, wherein a lock box on a window or door frame and a locking bolt adjacent thereto are fastened to a window or door leaf. The lock case has a recess into which a free end of the locking bolt can be inserted to form a locking position. In this locking position or closed position of the locking bolt is secured by a lock cylinder. In order to open the window or the door or to be able to move into a tilted position, however, the locking bolt must be moved by means of a sliding movement from its engaging in the recess of the lock box position. In the locking position of the locking unit tilting of the window equipped with it is not possible.

From the DE 91 00 582 U1 a locking unit is known, which comprises a window frame adjacent to a window sash and rotatable about a rotation axis locking wing. In the locking position of this locking unit of the locking bar overlaps the associated window sash, so that it is then not open. To open the window, the locking bar is pivoted by 90 degrees into a position in which he no longer engages over the window frame, so that the window can then be swung open. Also in this embodiment of a locking unit, it is not possible to move a window equipped therewith into an open tilted position when the blocking wing is in its locking position.
An anti-burglary window fitting, which consists of a receptacle forming a security striking plate and an angular, engaging therein locking pin or locking bolt, is from the DE 10 2014 003 942 A1 known.

A generic locking unit and a generic window and a generic door are from the DE 10 2012 103 277 B4 known. This document discloses a lock bolt rotatably mounted on a sash or door sash which cooperates with a lock seat adjacent thereto to a window or door frame or wall or sill portion for forming the lock unit. The locking bolt is pivotable, in particular rotatable, attached to the window or door and pivots to form the locking position laterally in a receptacle of the lock camp. The recording of the lock stock is designed such that a tipping into an open tilt position of the window is also possible when the lock bar is in its pivoted into the receptacle of the lock bearing position and thus the locking position of the locking unit. A disadvantage of this known locking unit is that the lock bearing the lock bolt opposes no resistance during a movement in a vertical upward direction from the receptacle of the lock out. Thus, although the known from this document locking unit prevents movement of the equipped with the locking latch window or door leaf in the horizontal direction of the associated Frame continues, but not vertically upwards. In the case of a vertical movement component of a window or door wing caused by levering out, this results in still insufficient protection with regard to a burglar-resistant effect of the locking unit.

The invention is therefore an object of the invention to provide a solution that also provides a vertically acting upward movement resistance in a locking unit with a laterally pivoting into the receptacle of a lock bearing locking bolt in the locking position.

In a locking unit of the type described in more detail, this object is achieved in that the locking bar has at one of its ends a first Abkrümmungsbereich and the lock has at one of its ends a receiving area forming second Abkrümmungsbereich, in which the first Abkrümmungsbereich to form the locking position the locking unit is laterally pivoted, wherein the first Abkrümmungsbereich and the second Abkrümmungsbereich form at least partially overlapping a horizontal and a vertical movement of the first Abkrümmungsbereiches blocking positive connection when the first Abkrümmungsbereich is pivoted in the locking position of the locking unit in the second Abkrümmungsbereich.

In a window or a door of the type described in more detail above, the above object is achieved in that the locking bar has at one of its ends a first Abkrümmungsbereich and the lock stock at one of its ends a receiving area forming second Abkrümmungsbereich, in which the first Abkrümmungsbereich for forming the locking position of the locking unit is laterally pivoted, wherein the first Abkrümmungsbereich and the second Abkrümmungsbereich form at least partially overlapping a horizontal and a vertical movement of the first Abkrümmungsbereiches blocking positive connection when the first Abkrümmungsbereich in the Locking position of the locking unit is pivoted in the second Abkrümmungsbereich.

Advantageous developments and expedient refinements are the subject of the respective subclaims.

Characterized in that the first Abziehungsbereich of the locking bolt and the second Abziehungsbereich of the lock bearing form a positive connection, which prevents horizontal and vertical movement of the first Abkrümmungsbereiches in the second Abkrümmungsbereich when the first Abkrümmungsbereich is pivoted in the locking position of the locking unit in the second Abkrümmungsbereich , an improved burglar-resistant locking unit and improved anti-theft burglary protection is provided. The positive connection begins both in the direction of each equipped with the locking unit window or door continues as well as in the direction perpendicular, ie vertical, acting on forces. Furthermore, the overlap of the first and second Abkrümmungsbereich also results in a resistance against twisting loads and consequent torsional movements, which can be caused by around a vertical axis and the horizontal axis directed away from the window and a longitudinal axis of the window acting force moments when trying to pry the window or door wing, as is the case with burglary attempts with conventional lever tools. Such a locking unit according to the invention is therefore sufficiently burglar resistant. Preferably, both the locking bolt and the lock bearing made of a sufficiently tensile material, such as stainless steel, optionally powder coated produced. Nevertheless, the locking unit according to the invention remains easy to use, since to form the locking position of the corresponding rotatable room inside the window or door-mounted locking bolt in a simple manner laterally in the receptacle of the lock stock can be pivoted. Due to the effect of gravity - the lock and the locking bolt are usually room inside the lower frame or the associated sill and the lower cross bar of a window or door mounted - holds the lock bolt and automatically in this Locking position until it is pivoted out again by applying a corresponding manual force from the locking position laterally with its end having the first Abkrümmungsbereich end.

It is advantageous for the formation of a positive connection when the first or second Abkrümmungsbereich has a protruding angle leg and the other of the two Abkrümmungsbereiche is formed as a U-profile, in which the respective angle leg to form the locking position of the locking unit laterally under training the positive connection can be pivoted. For example, if the second Abkrümmungsbereich the lock stock is designed as a "U" with opening towards the window or door, in which engages the first Abkrümmungsbereich of the locking bar, which as "L", one angle leg facing away from the window shaped is both forces in the direction away from the window, as well as in the vertical direction as well as moments in any direction in the locking position of the locking unit well record of locking bolt and lock.

It is according to the invention also possible that both Abkrümmungsbereiche are U-shaped, the angle leg of the first Abkrümmungsbereiches is thus part of a U-shaped Abkrümmungsbereiches. The invention therefore also provides that the first and second Abkrümmungsbereich are each U-shaped and engages in the locking position of the locking unit each have a leg of a U-profile to form the positive connection in the other U-profile.

Particularly advantageous is an embodiment of the locking unit according to the invention, in which the first Abkrümmungsbereich has an arrangement of the locking bolt in its use position in the direction of the window or the door fort protruding end portion and the second Abkrümmungsbereich a with arrangement of the lock in its use position with a leg in the direction on the window or the door to projecting angle portion, wherein the end portion of the first Abkrümmungsbereichs and the angle portion of the second Abkrümmungsbereichs are formed in their respective width and longitudinal extent matched to one another that the end portion for forming the locking position of the locking unit is laterally pivoted under the legs of the angle section and in the locking position of the locking unit of the pivoted end portion engages under the leg and is encompassed by the angle section, which the invention also provides.

It is then useful in a further development of the invention also, if the first Abkrümmungsbereich a locking bolt angle section with an arrangement of the locking bolt in its use position in the direction of the window or the door fort protruding end leg and the second Abkrümmungsbereich a receiving area forming and arrangement of the lock in its use position in the direction of the window or the door to open U-Profilendabschnitt, wherein the end leg of the locking bolt angle portion and the U-profile end portion of the second Abkrümmungsbereichs are matched in their respective width and longitudinal extent to each other such that the protruding end leg in the at least a circular path portion extending pivoting movement of the locking bolt laterally in the receiving area formed by the U-profile end portion and in a the locking position of locking bolt and Closing bearing forming relative position can be brought to the U-profile end of the lock stock, in which engages the pivoted end leg in the U-profile end.

In order to ensure that the window or door leaves a pivoting of the window or door wing in its open tilted position even when in its locking position located locking unit, the invention is characterized in a further development that the receiving area is dimensioned such that the in the Receiving area pivoted first Abkrümmungsbereich is rotationally tiltable in a downward direction movable.

According to an embodiment of the invention, a preferred embodiment of the closing bearing is that the closing bearing has a connecting plate connecting the second bending region to a mounting plate and carrying the second bending region.

For pivoted mounting of the locking bolt this is advantageously formed with a bearing hole penetrating two-piece stage bearings, which is why the invention further provides that the locking bolt has a bearing hole and the locking bolt bearing element comprises two step bearing elements with central bore having a diameter larger than the bearing hole dimensioned cover plate and engage each with a stepped storage area in the bearing hole. In this embodiment, a connecting means, preferably a screw, for fastening the composite of locking bolt and locking bolt bearing on the window or door leaf and serves as a rotation axis for the bearing. The inner surface of the bearing hole also serves as a bearing bush.

In this case, it is furthermore expedient for the two stepped bearing areas in the storage position of the locking bolt to engage one another with their surface sides in the bearing hole in the area of the bearing hole. Here, the stepped storage areas are each inserted from the opposite sides in the bearing hole of the locking bolt and both have a cover plate. By this configuration, a total of torsion very stiff storage is formed. In this case, in the case of the two-halve locking bolt bearing these halves abut each other exactly in the middle of the bearing hole and both have a cover plate on. In this case, the two locking bolt bearing elements are then formed symmetrically and can be made identical. It must be made in production so only one part, which can be used twice. Preferably, the two stage bearing elements and thus the two locking bolt bearing elements are formed differently thick, wherein the fitting in the use position on the window or door element is significantly thinner than the opposite element is formed and with its cover plate only the rotational movement of the locking bolt before or on the window - or door must ensure. In this case, the two locking bolt bearing elements with their Surface sides not centered, but in a window or door wing facing the last portion of the longitudinal extension of the bearing hole to each other. Here, the friction effect of the two abutting and superimposed surfaces may be high in such a way that a further friction element is not needed and may be omitted. In both embodiments, a positioning is given by the impact of the two end faces or surface sides, whereby the gap between the cover plate and locking bolt, in which preferably a brake element is located within the manufacturing tolerances is precisely determined and the resulting braking force can be well designed.

In order for the locking bolt to be able to maintain its open position against gravity in its open position when the locking unit is open, it is advantageous according to a further embodiment of the invention if it is equipped with a friction-increasing braking element, which is why the invention is characterized in that in that at least one cover plate has a friction force-increasing braking element on its surface facing the locking bolt. Preferably, a brake element can be provided on the cover plate on the side towards the locking bolt bearing. This holds the locking bolt then in any position against a small moment and is for example a plastic element, in particular a rubber element. By this device, the handling of the locking bolt is simplified by the user. If the locking element is mounted in its preferred position of use at the bottom of the window or door leaf, the locking bolt without a braking element by gravity could fall into the locking position, if the frictional force between the superimposed surface sides of the Schließriegellagerelemente not sufficient.

Preferably, the brake element is designed as a ring element, which comprises an annular body, on the inside of which spring elements and tongue elements projecting radially pointing in the direction of the center, which the invention further provides. In this way, in particular from plastic injection molding a brake element can be produced inexpensively. The spring elements additionally protrude upwards out of the plane of the ring element and, like the tongue elements, have a radially inwardly directed longitudinal extent on, which makes it possible to embrace a stepped storage area of the locking bolt bearing element.

In order to prevent in the locking position of locking bolt and lock bearing and the resulting relative position of locking bolt and lock bearing to each other in addition, a lateral pivoting of the locking bolt out of the receiving area, the invention provides according to another embodiment that the locking bolt at least one, especially as Langloch or elongated slot formed through hole and the lock bearing has two coaxial opposite receiving holes or that the locking bolt has two receiving holes and the lock bearing at least one through hole, wherein the respective at least one through hole and the respective two receiving holes at in the locking position of the locking unit in the second Abkrümmungsbereich swiveled first Abkrümmungsbereich face coaxially and in this one through the respective at least one through hole and the respective receiving holes extending and a lateral pivotal movement of the locking bolt blocking locking pin is inserted.

For the handling of such a locking pin and the locking possibility formed thereby, it is expedient if the passage opening in the end leg of the locking bolt and a receiving hole in the leg of the first Abkrümmungsbereichs and the opposite receiving hole in the region of the second Abkrümmungsbereichs in the first receiving hole opposite portion of the connecting plate are formed what the invention also provides. With this configuration, it is possible to easily take the locking pin to solve this locking position by hand and pull out of the openings and holes.

The window according to the invention and the door according to the invention are also distinguished by the fact that the lock bearing is fastened on its side opposite the second Abkrümmungsbereich side by means of an engaging in the formed between the frame and rollover of the window or the door gap mounting plate to the frame. This will be a created further anchoring point in the gap, which opposes a levering or bending of the lock bearing a force resistance.

In order to fix the locking bar preferably rotatable by 360 ° to the window or door, the invention also provides in an embodiment of the window and the door that the locking bolt has a bearing hole and guided in its use position of the locking bolt bearing element in a bearing hole on the Window or door is attached.

Finally, it is also provided in an embodiment of the window or the door that they are characterized by a locking unit according to one or more of claims 1-13.

In the Fig. 1 represented and designated overall by 1 locking unit comprises a locking bolt 2 and a lock camp 3. In the in Fig. 1 illustrated use position of the locking bolt 2, this is rotatably mounted by a screw 4 in the region of the window overlap 27 on a window sash 5 by 360 degrees. The fastening takes place by means of a locking bolt bearing element 6, which engage in two stepped bearing areas 6.1 and 6.2, each with its protruding from a respective cover plate 7.1, 7.2 level in the formed in the locking bolt 2 bearing hole 8. Are centrally in the two stage bearing elements 9.1, 9.2 of the locking bolt bearing element 6 holes 11.1, 11.2 formed, which are penetrated centrally in the locking bolt 2 on the window sash 5 of a window 10 defining use position of the screw 4. On the inner bearing surface of the cover plate 7.1, which surrounds the stepped bearing region 6.1, the inside of the bearing, facing the locking bolt 2, an annular brake element 12 is arranged. The respective stage of the stepped bearing areas 6.1, 6.2 and the cover plate 7.1 and 7.2 firmly connected thereto are formed in a circular disk, wherein the steps fit exactly to the diameter of the bearing hole. 8 are adapted and the cover plates 7.1, 7.2, in contrast, have a larger diameter, so that the steps engage in the bore and come with their opposite circular disc surfaces or surface sides 13.1, 13.2 in the bearing hole 8 to butt, so that the bearing hole 8 in its thickness extension as Bearing bush for the positioned with its superimposed surface sides 13.1, 13.2 in the region of the bearing hole locking bolt bearing element 6 acts. The on its the locking bolt 2 facing surface Reibungskrafterhöhend acting brake element 12 keeps the locking bolt 2 against low moments, such as the resulting from gravity and the mass of the locking bolt 2 moment, fixed in any position. However, the necessary moment to overcome the braking torque given by the braking element 12 and to turn the locking bolt 2 is so small that a user can apply it manually. In the in the Fig. 1 shown use position of the locking bolt 2, this is guided by the locking bolt bearing element 6 in the bearing hole 8 and fixed by means of the screw 4 to the sash 5. In this way, the locking bolt 2 is rotatably mounted in its use position by means of the locking bolt bearing element 6 360 degrees on the window sash 5, so that it swivels in its pivoting on a circular path portion laterally in a formed by the lock 3 receiving area 14 in the in the Fig. 1 shown locking position of the locking unit 1 is einschwenkbar. For this purpose, the lock bearing 3 is attached in a corresponding position adjacent to the locking bolt on the frame 15 of the window 10. In the in Fig. 1 illustrated locking position of the locking bolt 2 by means of a locking pin 38 which extends through a through hole (26) of the locking bolt 2 and the closing body 3 formed receiving holes 34.1, 34.2 extends secured against lateral pivoting.

The locking bolt 2 is formed overall in the form of an angle 16, which at its end, which is opposite to the bearing hole 8 having end portion, a projecting angle leg 17 which forms a first Abkrümmungsbereich 18. In the embodiment according to the Fig. 1 shown use position is the angle leg 17 and thus the first Abkrümmungsbereich 18 with one of the angle leg 17 formed End portion 19 in the direction of the window sash 5 and from the frame 15 fortweisender direction (direction H) out. In this respect, the first Abkrümmungsbereich 18 is formed as a closing bolt angle portion 20 with a forthe forth from the window 10 end leg 21. In this end leg 21 formed as an elongated slot through hole 26 is formed, which is open to the end portion 19 of the angle leg 17. The through-hole 26 is arranged centrally in the width extension B _{2 of} the angle leg 17. Furthermore, the passage opening 26 extends from the end portion 19 facing edge by about half of the longitudinal extent L ₂ in the angle leg 17 in. This special dimensioning ensures that a secure locking of the locking bolt 2 is ensured by locking and blocking the locking bar 2 in its locking position by means of the locking pin 38 in particular against lateral pivoting when inserted locking pin 38 and leveraging the locking unit is much more difficult.

The lock camp 3 has a mounting plate 22, with which it in his in Fig. 1 shown use position on the frame 15 rests and with two screws 23, the corresponding openings 24.1, 24.2 of the mounting plate 22 pass through, is attached. In this position, the trained in a corresponding thickness mounting plate 22 engages with a clamping portion 25 in between the wing flap 27 of the window sash 5 and the frame 15 remaining gap 28 a. In this respect, the thickness or thickness of the mounting plate 22 in this clamping region 25 corresponds to the usual gap between the window sash 27 and window frame 15. From the surface of the mounting plate 22 is at the lower edge of a connecting plate 29 shows that at its mounting plate 22 opposite end a second Abkrümmungsbereich 30 carries. This second Abkrümmungsbereich 30 is formed in the embodiment, a total of U-shaped and comprises a perpendicularly projecting from the connecting plate 29 angle portion 31 which has a in the direction of the mounting plate 22 to (direction H ') protruding leg 32. The leg 32 in the vertical direction opposite region of the connecting plate 29 forms the second leg to form the U-profile or a U-profile end portion 33 of the second Abkrümmungsbereichs 30 from. This indicates the second Abkrümmungsbereich 30 a the receiving portion 14 forming U-profile end portion 33. In the in the Fig. 1 shown use position of the lock camp 3, this U-profile end portion 33 in the direction of the window 10, here the frame 15, to (direction H ') positioned open, ie the opening of the U-shaped second Abkrümmungsbereiches 30 is from the side of the window 10 ago , but also accessible from the side.

Furthermore, the receiving holes 34.1 and 34.2 are formed in the U-profile section 33 of the lock bearing 3. The receiving hole 34.1 is formed in the leg 32 of the lock stock 3 and arranged approximately in the middle of the width extension B _{3 of} the leg 32. Another receiving hole 34.2 is arranged coaxially with the first receiving hole 34.1 in the region of the second bending region 30 and the U-profile section 33, the connecting plate 29 penetrating in the connecting plate 29. The receiving hole 34.2 is disposed approximately in the center of the widthwise extension B _{3 of} the connecting plate 32, so that the positions of the receiving holes 34.1 and 34.2 in widthwise extension are coaxially arranged one above the other. Thus, the receiving hole 34.1 is arranged above the receiving hole 34.2 such that the receiving holes 34.1 and 34.2 are aligned with each other in the vertical direction V. The receiving holes 34.1, 34.2 serve to receive the locking pin 38th
The first Abkrümmungsbereich 18 can pivot laterally into the receiving area 14 and are pivoted in a tilt-open position during opening of the window 10 or the door rotationally tiltable. Likewise, the angle leg 31 and the second Abkrümmungsbereich 30 such a height in the vertical direction V that in the fixed frame 15 on the use position of the lock bearing 3, the window sash 15 remains pivotally movable over it.

The first Abkrümmungsbereich 18 of the locking bolt 2 and the second Abkrümmungsbereich 30 of the lock 3 and thus according to embodiment in particular the end leg 21 of the angle leg 17 in its end portion 19 of the locking bolt 2 and the angle leg 31 with its leg 32 of the lock stock 3 are with respect to their longitudinal extent in the horizontal Direction H, H 'and their height extent in the vertical direction V dimensioned and formed adapted to each other, that the locking bolt 2, when in his in Fig. 1 shown use position is pivotally mounted on the window sash 5, and the lock camp 3 in his also in Fig. 1 shown use position is fixedly arranged on the window or frame 15, in its movement on a circular path in the course of a circular path section laterally in the receiving area 14 can be pivoted, whereby then the in Fig. 1 illustrated locking position of locking bolt 2 and lock 3 is formed. The first deflection region 18 can thus be pivoted laterally into the second deflection region 30 forming the receiving region 14, wherein the first and second deflection regions 18, 30 are further formed and shaped such that they at least partially overlap in this locking position and a horizontal (direction H ) and form a vertical (direction V) movement of the first Abkrümmungsbereiches 18 blocking positive connection when the first Abkrümmungsbereich 18 is pivoted in the locking position of the locking unit 1 in the second Abkrümmungsbereich 30. Here, in the exemplary embodiment, the second bending region 30 of the closing bearing 3 is designed as a U-profile end section 33, wherein the angle leg 17 of the locking bolt 2 pivots in laterally below the leg 32 of the closing bearing 3. But it is also quite possible, the first and second Abkrümmungsbereich 18, 30 form such that the lock bolt 2, a U-profile end portion is formed in this U-shaped opening, which is then accessible from its side facing away from the window 10, a directed towards the window 10 (direction H ') protruding leg of the lock camp 3 engages. It is also conceivable that both the first Abkrümmungsbereich 18 and the second Abkrümmungsbereich 30 is each formed as a U-profile end, which are then aligned with the U-shaped openings opposite each other and in the locking position with at least one leg in the U- engage shaped opening of the other Abkrümmungsbereiches.

In the locking position of the locking bolt 2 is relative to the lock 3 by means of the locking pin 38 verschwenksicher arrested. For this purpose, the locking pin 38 engages both in the through hole 26 of the locking bolt 2 and in the receiving holes 34.1, 34.2 of the lock 3 a.
