Description

The invention relates to a locking fitting for locking a wing of a window, a door or the like on an associated fixed frame, wherein on a sash and on a side opposite this folding frame on the one hand at least one locking element and on the other hand at least one Bolt abutment is arranged and at least one locking element by means of an actuator in a supply and in a Unlocked position is movable and in the locked position the associated latch abutment perpendicular to the sash and effectively behind the Rahmenfalz.

Such locking fittings are in particular for security of window or door wings against unauthorized violent Open used. With locked wing in the gap between wing and frame rebate a burglary tool in shape a lever attached and with this the wing in the direction its main plane subjected to force, so acts the locking fitting the intended forcible transfer of the Wing perpendicular to the wing and the Rahmenfalz opposite.

Disclosed is a generic locking fitting in DE-A-44 17 842. As a locking element serves a locking pin, by means of a drive rod in the longitudinal direction of the relevant Flügelfalzes is displaceable and the fixed frame side one Mushroom head has. Associated with the locking pin is an on the opposite frame rebate attached strike plate, the provided with a slot-like inlet for the locking pin is. For locking the relevant wing is the Locking pin by means of the drive rod in the folding longitudinal direction a position outside the striker in a position to convict, in which he retracted into the inlet of the strike plate is and at its mushroom head with the edges of the enema overlapped on the strike plate. In particular in the folding longitudinal direction However, the extent of this overlap is proportionate low. Reason for this is the fact that the length of the extending in the folding direction switching path of the drive rod for moving the attached thereto bolt from the Ent- limited to the locking position due to the function is. The locking pin can be seen in the folding longitudinal direction Retract only over a relatively short distance in the strike plate and with its mushroom head the inlet edges of the strike plate engage behind. The extent of this grip, so the extent the overlap of the mushroom head on the locking pin and the inlet edges on the strike plate in the folding longitudinal direction, is now but co-determining the size of the resistance that the Positive connection of locking pin and striking plate one violent relative movement of wings and fixed frame vertically to the relevant sash and the relevant frame rebate opposes.

From DE-A-198 46 307 is a non-generic ventilation device known, in the case of those in the fold between a window or a door leaf and an associated frame sealing rails are housed. These sealing rails are in one Folded groove of the frame and added there in a folding longitudinal direction extending axis of rotation rotatably mounted. By Rotation about this axis of rotation can be the previously known sealing rails between a position in which she the folding gap for air passage and a position in which they Seal the seam gap, move back and forth. In her sealing Rotary position are the sealing strips with their longitudinal edges at one parallel to the main plane of the sash and the frame extending sealing surface of the wing. A vertical to the wing as well as the Rahmenfalz effective connection between Wing and frame is made by means of the sealing rails not manufactured.

Object of the present invention is the previously known generic locking fitting in the sense of an increase to further develop the achievable burglary security.

This object is achieved according to the invention by the feature combination according to claim 1. The formation of the locking element as a tie bar with running in the folding longitudinal direction Bolt edge in combination with the described kinematics the locking movement allows between locking element and bolt abutment a rear grip with large extension in Produce folding longitudinal direction. In extreme cases, the Riegelkante on the bolt bar over the entire length of the relevant Folds extend. Accordingly large area and thus Correspondingly effective is the positive locking, which is at the locking position befindlicher bolt bar between Wing and fixed frame results and that of a violent shift the wing opposite the fixed frame perpendicular to counteracts the wing and the Rahmenfalz. This effective If appropriate, positive connection can also be achieved achieve with a short switching path of the actuator used. So can by means of appropriate gear technical measures be ensured that even short switching paths of Actuator sufficient, the bolt bar on the required Angle of rotation from the Ent- to the locking position and conversely convict. The above advantages of the invention Lock fitting set up independently of whether the tie bar on the wing or on the fixed Frame and accordingly the latch abutment on the fixed Frame or are arranged on the wing.

Particular embodiments of the invention according to claim 1 result from the dependent claims 2 to 12.

In the patent claims 2 and 3 are inventions types described, characterized by a structurally simple design Distinguish the used tie bar.

The leader as it according to claim 4 in development the invention is provided, on the one hand guarantees a defined movement of the locking bar in the locking and / or in the unlocking direction. On the other hand, the leader piece be used to create a load-bearing connection between the bolt bar and the wing or the fixed Frame.

The invention types according to claims 5 and 6 are on the one hand constructive or production engineering View preferred. In addition, the coaxiality of the Guide surface on the one hand and the guide counter surface on the other a large-area contact between the bolt bar and its leader. This large-area contact in turn causes both a defined leadership of the tie bar in the Movement in the locking or in the unlocking direction as well as a strong support of the tie bar on the guide piece and about this on the wing or on the fixed frame.

A double, perpendicular to the wing and the Rahmenfalz effective fit and thus an extremely pronounced Securing the wing against forcible displacement in the main plane of wing and fixed frame results in the case the locking fitting of the invention according to claim 7. The bolt edges of both demanding tie-bars can extend in extreme cases over the entire fold length. Correspondingly large area is the rear handle of the tie bars at the assigned or the bolt abutments.

Constructionally particularly simple designed locking fittings for producing a double positive connection between Wings and fixed frame are in the claims 8 and 9 described.

As shown in the claims 10 and 11, the bolt abutment inventive locking fittings immediately from the wing or from the fixed frame or from separate ones Be formed abutment fittings. The former Variant is characterized in that the locking fitting only a relatively small number of fittings includes. In the case of the second-mentioned Erfindungsbauart is advantageously the possibility of wings or fixed frames without safety devices with corresponding Retrofit fittings and / or as bolt abutment components to use, for example, in choice of materials and strength are specially adapted to their safety function.

Finally, claim 12 describes a suitable possibility the actuator of tie bars according to the invention Design locking fittings. The push rod drive can be done both manually (for example via a standard rotary handle) as well as mechanically (for example by means of an electric motor) respectively. The slide control is to be interpreted in such a way that the push rod movement in the desired rotational movement the tie bar can be implemented.

1, a window 1 comprises a wing 2 and a this stored fixed frame 3. As indicated by dashed lines, is the wing 2 relative to the fixed frame 3 by a vertical Axle rotatable and tiltable about a horizontal axis. to Close locking of the wing 2 serve on the fixed frame 3 Locking fittings 4, as described in detail below and how they are marked on individual or all Positions can be mounted. As well as a manual operation handle 5, the locking fittings 4 are part a drive rod fitting, which shows the different functional positions of the wing 2 allows.

Like the Fign. 2 to 5 can be seen, includes the locking fitting 4 in a first type a tie bar 6, which is attached to a sash 7 and a bolt abutment 8 at a Rahmenfalz 9. As a bar abutment 8 is used while a profile strip of the solid frame 3 forming Frame profile. The bolt bar 6 is a metallic hollow cylinder segment.

About a guide piece 10, the bolt bar 6 is on the wing 2 supported perpendicular to the sash 7. Two retaining bolts in Shape of rivet pin 11 enforce the guide piece for this purpose 10, the tie bar 6, one in the usual way with the wing 2 bolted faceplate 12 and one at the bottom the faceplate 12 guided drive rod 13. The latter is located inside a wing-side fitting part 14, which is covered by the faceplate 12. The passages the rivet pin 11 on the guide piece 10 and on the Driving rod 13 are designed as circular holes whose Diameter of the outer diameter of the relevant section the rivet pin 11 corresponds. The faceplate 12 is of the Rivet pin 11 interspersed with oblong holes in the longitudinal direction the Flügelfalzes 7 run and thus a longitudinal displacement the drive rod 13 with the rivet pin 11 and the guide piece 10 allow relative to the stationary faceplate 12. In Longitudinal direction of the sash 7 also arranged stationary is the bolt bar 6, which by means of Stulpschienenfester projections 15 is supported against movement in the folding longitudinal direction.

Of the rivet bolt 11, the bolt bar 6 is on slotted slots 16 steeped. These have in particular demonstrably the fig. 2a to 2c each have three sections, namely one extending in the apex line of the bolt bar 6 section 16.1, an adjoining helical on the Coat the bolt bar 6 extending section 16.2 and a following and parallel to the crest line of the tie bar 6 extending section 16.3. The width of the sections 16.1, 16.2, 16.3 of the guide slots 16 is slight greater than the diameter of the interspersed Part of the rivet bolts 11. Together with the latter form the Slotted slots 16 a slide control for the bolt bar 6th

To transfer the wing 2 in its various functional positions is the manual operation handle 5 to turn. extends the manual operation handle 5 in Fig. 1 horizontally right, so is the entire espagnolette fitting on the window 1 in its rotational readiness state, i. the wing 2 can be opened in rotation about its vertical axis of rotation. The rivet pins 11 take on the bolt bar 6 in Fig. 2c with 11.1 designated position.

Passes the manual operating handle 5 in Fig. 1 vertically above, so is the espagnolette of the window 1 in its Kippbereitschaftszustand and the wing 2 can order its horizontal tilt axis relative to the fixed frame 3 in be tilted a tilted position. The rivet pins 11 are located on the bolt bar 6 in the position 11.2 according to Fig. 2c.

Both when turning and when ready to tilt the Espagnolette fitting takes the bolt bar 6 in Fig. 4th shown position. For closing lock of the wing 2 on the fixed frame 3 is the manual operation handle 5 from his horizontal, the rotary standby position of espagnolette fitting assigned position down in the dashed Turn position shown in FIG. 1. As a result of the associated Movement of the drive rod 13 move with the drive rod 13 connected rivet pins 11 from their position 11.1 as shown in FIG. 2c by the helical portions 16.2 the gate slots 16, until they finally in the crest line parallels Enter section 16.3 of the guide slots 16 and there take the position 11.3 of FIG. 2c. after the Driving rod 13 with the rivet bolt 11 in the longitudinal direction of the sash 7 guided in a straight line, the bolt bar 6 but a with the axis of the hollow cylinder segment coincident axis of rotation 17 is rotatably mounted, causes the rectilinear movement the rivet pin 11 in the longitudinal direction of the Flügelfalzes 7 a rotation the bolt bar 6 in the direction of an arrow 18 in Fig. 5th The arrow 18 describes the locking direction of rotation of the locking bar 6th

At the end of their movement in locking direction 18 engages behind the bolt bar 6 with one in the locking direction 18 leading and extending in folding longitudinal direction Bolt edge 19, the fixed-frame-side latch abutment. 8 It results so between the wing 2 and 3 fixed frame perpendicular to the sash 7 and to the frame rebate 9 more effective Positive connection (FIG. 5). This connection of wing 2 and solid Frame 3 can also be inserted into the gap between Sash 7 and frame rebate 9 inserted lever only difficult to solve. Also it is from outside the wing 2 locked room barely possible, the bolt bar 6 in Unlock unlocking direction (arrow 20 in Fig. 5). Such an unauthorized provision of the bolt bar 6 acts the support of the located in position 11.3 of FIG. 2c Rivet pin 11 at the concerned, in the direction of Vertex line of the bolt bar 6 extending boundary of Slotted slot 16 against. Be carried out without further ado can a return movement of the locking bar 6 from the Ver in the unlocked position by turning the handle 5 off his in Fig. 1 vertically downwardly facing position in the horizontal, the rotation standby condition of the espagnolette fitting assigned position.

Both when moving in locking direction 18 than also when moving in unlocking 20, the Tie bar 6 on a coaxial with the axis of rotation 17 extending Guide surface 21 on a likewise coaxial with the Rotation axis 17 extending guide counter-surface 22 on the guide piece 10 led. The contact with the guide piece 10 located part of the bolt bar 6 accordingly forms a Rotation guide part.

As an alternative to that shown in solid lines in FIG. 2c Course can the slide slots 16 on the bolt bar. 6 also be formed as shown in dashed lines in Fig. 2c. In this latter case, the bolt bar 6 at Tilting condition of the espagnolette fitting a locking position one. The bolt bar 6 can then be arranged at the lower horizontal cross member of the wing 2 as Part of a Flügelkipplagers be used.

As indicated by dashed lines in Fig. 5, the locking edge 19 can also be bent over the remaining bolt bar 6. This allows the effectiveness of the rear grip on the bolt abutment 8 perpendicular to the Flügelfalz and the Rahmenfalz 9 still improve.

According to FIGS. 6 and 7, the locking fitting 4 in a second type a guide piece 110, which differs from the guide piece 10 described above differs. So is the guide piece 110 part of a housing 123, the one piece is formed with a faceplate 112. In addition, that leads Guide piece 110, the bolt bar 6 both on the inner surface of the jacket (Guide surface 21) and on a shell outer surface 124. Accordingly, the guide piece 110 next to the convex guide mating surface 22 of the outer shell surface 124th the bolt bar 6 associated concave guide counter surface 125th on.
