The invention relates to a locking device for windows and doors with a frame component that can be coupled to a window or door frame and a wing component that can be coupled to a window or door leaf, wherein the leaf component comprises an actuating unit for at least one locking element and the frame component comprises a locking latch and the locking element provided in the leaf component can be blocked by means of a locking cylinder that can be actuated with a key.

Such locking devices are generally known and are preferably used as additional burglary protection for windows and doors.

One object of the invention is to provide a locking device which ensures effective protection for windows and doors against unauthorized opening in the simplest and safest way possible.

This object is essentially achieved according to the invention in that the actuating unit can be operated in an automatic mode in which the locking element can be switched from its unlocking position to its locking position by means of the actuating unit when the key is removed and can be blocked in its locking position.

With the locking device according to the invention, the locking element can be moved into its locking position by hand and locked there even without a key. This is particularly advantageous if you want to close the windows and/or doors with the locking device according to the invention shortly before leaving your apartment or house.

would like to provide additional security but does not have the key to hand. The invention, which allows locking even when the key is removed, prevents the situation in the cases described from being neglected due to negligence. The flexibility in operating the locking device according to the invention therefore makes a significant contribution to increasing the burglary security of apartments or buildings.

According to one embodiment of the invention, in the unlocking position of the locking element, the key can only be removed in a position of the locking cylinder in which the automatic mode of the actuating unit is activated, which ensures that when the key is removed, the locking element is automatically blocked in its locking position. The effectiveness of the locking device according to the invention in preventing the risk of break-ins is increased even further in this way.

In a further embodiment of the invention, the actuating unit protrudes at least partially from the sash component approximately perpendicular to the base surface of the sash component, whereby the part of the actuating unit protruding from the sash component is preferably designed as an actuating element, in particular as a preferably ergonomically shaped rotary knob. This significantly improves the handling of the locking device according to the invention, since its actuating element is arranged at a certain distance from potentially disturbing components - such as fittings on the window or door - and is therefore easily accessible to the user.

Further advantageous embodiments of the invention are specified in the subclaims.

The invention is described below by way of example with reference to the drawing, in which:

Fig. 1 is a plan view of an embodiment of a locking device comprising a wing component and a frame component according to the invention, in which two locking elements are each in their locking position,

Fig. 2 is a perspective view of the wing component of the locking device of Fig. 1, and

Fig. 3 is a perspective view of the frame component of the locking device of Fig. 1.

The locking device 1 according to the invention shown in Fig. 1 comprises a wing component 2 and a frame component 3. Two essentially identical locking elements 4, 4' are rotatably mounted in the wing component 2, the axes of rotation 4a, 4'a of which run essentially parallel to one another and perpendicular to a base area with an approximately rectangular cross-section that can be coupled to a window or door wing (not shown).

The locking elements 4, 4' can be switched between their locking position shown in Fig. 1, in which they partially protrude from the wing component 2, and an unlocking position, in which they are completely accommodated in the wing component 2, by means of an actuating unit, of which an actuating element designed as a rotary knob 6 with a locking cylinder 8 is shown in Fig. 1. The rotary knob 6

protrudes essentially parallel to the axes of rotation 4a, 4'a of the locking elements 4, 4 ¹ on the side of the wing component 2 facing away from the base surface that can be coupled to the wing.

The provision of the actuating unit and its rotary knob in the sash component advantageously ensures convenient operation of the locking device according to the invention, since the rotary knob is arranged from the outset at a distance from a wall delimiting the window opening or from a door frame and is therefore easier to access.

Coupled to the rotary knob 6 is a locking mechanism (not shown) housed in the sash component 2, which is connected to the locking elements 4, 4' and converts a rotary movement of the rotary knob 6 into synchronous rotary movements of the locking elements 4, 4 ^' .

Preferably, the actuating unit is designed such that a rotation of the rotary knob 6 in a clockwise direction causes a rotation of the locking elements 4, 4' in an anti-clockwise direction and vice versa.

The rotary knob 6 of the operating unit houses the locking cylinder 8, which can be operated by means of a key (not shown), and can be switched between two different working angular positions with respect to the rotary knob S.

In the angular position of the locking cylinder 8 indicated in Fig. 1, the actuating unit is in an automatic mode. In this automatic mode, the locking elements 4, 4' can be pivoted into their locking position shown in Fig. by turning the rotary knob 6, but the locking elements 4, 4' are automatically blocked immediately after reaching the locking position, so

that they cannot be returned to their unlocking position by turning the rotary knob 6 in the opposite direction.

To remove the blockage, it is therefore necessary to return the locking cylinder 8 to a working position using the key, whereupon the locking elements 4, 4 ¹ can be pivoted back into the wing component 2. The locking cylinder 8 is designed in such a way that the key can only be removed when the locking cylinder 8 is in the automatic position, i.e. when the automatic mode of the actuating unit is activated.

This advantageous design of the locking device according to the invention ensures that when the key is removed, either the locking device is already in the safe, i.e. locked and blocked, state or the automatic mode of the actuating unit is activated, so that by simply operating the rotary knob 6 without a key, the locking device is locked and automatically blocked and the window or door in question can be secured in this way.

Preferably, all components required to implement the automatic mode of the operating unit are housed in the rotary knob 6, so that the entire automatic mechanism is spatially separated from the remaining locking mechanism provided in the wing component 2. In economic terms, this results in the advantage that the wing component 2, including the locking mechanism, can be manufactured in a conventional design and does not have to be adapted to the automatic function.

The frame component 3 of the locking device according to the invention has a base area that can be coupled to a window or door frame and is smaller than the corresponding base area of the sash component 2. With essentially the same size side surfaces facing each other as shown in Fig. 1, the frame component 3 is thus narrower than the sash component 2, which preferably has approximately two to three times the width of the frame component 3.

This design has the advantage that the locking device according to the invention can be used without any problems even when there is little space available on the frame due to the narrow frame component. On the other hand, the large base area of the sash component allows fastening screws to be distributed over a flat area in an advantageous manner, which makes it more difficult to forcibly detach the sash component from the sash due to the large leverage required for this.

The side surface of the frame component 3 facing the sash component 2 is provided with a receiving opening 7, 7' for each locking element 4, 4 ^' , through which the section of the respective locking element 4, 4' that can be pivoted out of the sash component 2 can be guided into the frame component 3. An edge region delimiting the respective receiving opening 7, 7' serves as a locking element 7a, 7'a that blocks the respective locking element 4, 4' in its locking position.

Preferably, the locking elements 4, 4' are designed as metal disks with a semicircular cross-section and with a thickness that is constant over the cross-sectional area, which each have a projection 4b, 4'b protruding from the plane of the disk on their section that can be pivoted out of the sash component 2. These projections 4b, 4'b engage behind

Locking device and, when the locking elements 4, 4' are in the locking position, the respective locking element 7a, 7'a of the frame component 3.

In the sections protruding from the wing component 2 in the locking position, a recess 4c, 4'c is formed adjacent to the wall-like projection 4b, ^4'b , in which the respective locking element 7a, 7'a is arranged when the locking device is mounted and locked.

Preferably, the actuating unit of the locking device according to the invention is designed in such a way that it engages tactilely and audibly when the locking elements 4, 4 ^' reach the unlocking position and the locking position. The locking device according to the invention thus gives the user a pleasant operating feeling and shows him the respective position of the locking elements 4, 4' in a reliable manner.

Fig. 2 and 3 show perspective views of the wing component 2 and the frame component 3.

In the frame component 3 (Fig. 3), the receiving openings 7, ⁷¹ can be seen, which have a substantially rectangular free cross-sectional area into which the area of the material surrounding the relevant receiving opening 7, 7' serving as the respective blocking element 7a, 7'a protrudes. Apart from the receiving openings 7, ^71, the frame component 3 is a solid component, which is preferably made of metal.

The wing component 2 (Fig. 2) comprises a stable base plate 11, which can be coupled to the window or door wing, as well as a stable attachment 12, which are preferably made of metal and, when assembled, form a housing for

the locking elements 4, 4' and the actuating unit. The rotary knob β of the actuating unit protrudes from the side of the housing 11, 12 facing away from the base plate 11. Preferably, the locking elements 4, 4 ^' are rotatably mounted on pins 12a, 12'a which are attached to the attachment 12 and can be seen in Fig. 1 and which extend to the base plate 11.

In the locking position shown in Fig. 1 and Fig. 2, the approximately semicircular locking elements 4, 4' are each pivoted out of the sash component 2 by approximately 90°, so that their flat lateral boundary surface is approximately perpendicular to the side surface of the sash component 2 facing the frame component 3 in the assembled state.

The sash component 2 and the frame component 3 are each detachably connected, preferably locked, to a cover cap 9, 10, preferably made of plastic. The connection points between the cover cap 9 and the sash component 2 and between the cover cap 10 and the frame component 3 are preferably only accessible via the base surfaces that can be coupled to the sash or the frame, so that the cover caps 9, 10 cannot be removed when the locking device is installed or can only be removed by using force to damage the respective cover cap 9, 10.

The frame component 3 is provided with three holes 13, which extend from its base surface, which can be coupled to the frame, to its upper side, which is exposed when the cover cap 10 is removed. The holes 13 serve to accommodate screws with which the frame component 3 can be fastened to the frame.

In the preferred embodiment of the wing component 2, its base plate 11 is provided with six holes 14. Two of these holes are connected to the holes known as

Pivot bearings for the locking elements 4, 4' are aligned with the pins 12a, 12'a of the attachment 12. The pins 12a, 12'a are each provided with an internal thread in order to secure the base plate

11 and the attachment 12 can be screwed together to form the housing of the wing component 2.

The four remaining holes 14 of the base plate 11 are aligned with corresponding holes 15 in the attachment 12 and enable the sash component 2 to be screwed to a door or window sash. Preferably, two of these holes 15 provided in the attachment 12 only serve as passages for a tool, e.g. a screwdriver, in order to attach the base plate 11 to the sash when connected to the attachment 12 or to detach it from it. The base plate 11 and the attachment can be screwed to the sash via the other two holes 14.

12 are screwed to the wing as a unit.

This design of the sash component makes it possible to dispense with the screws that can be brought into engagement with the pins 12a, 12'a of the attachment 12 for connecting the base plate 11 and the attachment 12 and instead to first attach the base plate 11 alone to the sash. The attachment 12 can then be screwed to the sash using locking elements 4, 4' that are pivotally mounted on the pins 12a, 12'a and thus connected to the base plate 11 to form the sash component housing.

It can be seen from Fig. 2 and 3 that the construction height perpendicular to the respective base areas of both the sash component 2 and the frame component 3 is essentially determined only by the thickness of the disc-shaped locking elements 4, 4 ^' . In conjunction with Fig. 1, it is also clear that the construction size of the frame component 3 is essentially determined only by the sections of the locking elements 4, 4' that can be pivoted out of the sash component 2.
