-
EP 1 873 336 discloses a lock assembly for a ventilating window having a sash arranged to be openable with respect to a main frame by pivotal movement about an axis parallel to a pair of opposed sash members. This lock assembly comprises a striking plate fixed to a main frame member opposite one of the pair of sash members and a casing fixed to one sash member opposite the striking plate. A locking mechanism is arranged in the casing and the locking mechanism is operable by an operator member accessible from the inside of the window via an actuator slide displaceable in a slot in the casing between a first end position defining the unlocked position, a second end position defining the locked position and a third, intermediate position where the window is slightly open to achieve ventilation. Two pawl members protrude through slots in the casing. When the window is shut the pawl members come into engagement with a fixed striking plate whereby they are forced sideward and snap into their locked position. For the purpose of ventilation, the actuator slide is pulled half way back towards a first position by use of the operator member without the pawl members being displaced. - It is a requirement that windows are burglar proof to highest possible extend, though of course without increasing the cost of the window and the locks to an unacceptable level.

Figures 1 to 5 show various views of a lock assembly according to an exemplary embodiment of the invention. Infigure 1 the lock assembly and the striking plate assembly are mounted in a ventilating window. - In
figure 1 thecasing 10 of the lock assembly is shown in a mounted position secured to thesash member 4 by means of screws inserted throughfastening holes 17 and by thefastening pins 26 which extend from thecasing 10. Theoperator arm 12 is secured to theoperator member 2 of the window by means of screws through fastening holes of theoperator hinge 13. Infigure 1 theactuator slide 16 is shown in the locked position in which the window is locked and cannot be opened without activating the locking assembly. The operator member is pivotally suspended from thesash 4 by ahinge 9. An operator can grab thehandlebar 3 that is connected to theoperator member 2, to move theoperator member 2 as indicated by the arrow between various positions whilst theoperator member 2 pivots about thehinge 9. - A
striking plate assembly 50 is secured to thewindow frame 5 by screws and fasteningpins 56. - The lock assembly 1 has a
casing 10 that encases a locking mechanism and comprises fasteningholes 55 for mounting the locking assembly to a topsash member 4 of a window sash. - The locking mechanism includes two
locking arm members 22 that are each provided with apawl member 20. Thepawl members 20 extend throughcurved slots 18 in the casing. Theactuator slide 16 extends through astraight slot 15 in the casing. Fasteningpins 14 are used for pivotally suspending thelocking arm members 22 from thecasing 10. - The
actuator slide 16 is preferably mounted with afriction plate 49 and anoperator arm 12 mounted with ahinge pin 21 to the part of theactuator slide 16 that extends through thecasing 10. The other end of theoperator arm 12 is connected to theoperator member 2 by means of anoperator hinge 13 with fastening holes. - The locking mechanism has
link arms 24 withcutouts 23, and lockingarm members 22 within one end bend over to form thepawl members 20. Thus, the lockingarm members 22 have a substantially straight portion that ends at a bend 39 (figures 6 and 8 ) after which thelocking arm 22 continues as thepawl member 20. The other end of thelocking arm members 22 are suspended from the casing by a hinge that includes the fastening pins 14. The locking mechanism also hasfirst spring wires 25 andsecond spring wires 27. Each of the lockingarms 20 is connected near itsbend 39 to a one end of alink arm 24 by ahinge 28. The other end of thelink arms 24 is connected to theactuator slide 16 by ahinge 29. - The
actuator slide 16 is moveable between three resting positions. A first, unlocked position in which the window is open or can be opened without activating the locking assembly, which is shown by the interrupted lines infigure 3 (with theoperator hinge 13 in the position to the extreme right as seen infigure 3 ). The actuator slide can also rest in a second, locked position in which the window is locked in a closed position (figure 1 ) and a third, intermediate position where the window locked but the operator member is in a tilted position to slightly open the window for achieving ventilation (the intermediate position infig. 3 ). - The
actuator slide 16 and thelocking arm members 22 are interconnected via the locking mechanism, which comprises a system of the second and the first spring-loadedlink arms 24 and the first and thesecond spring wires actuator slide 16 to move stepwise between said three positions while thepawl members 22 only move between a locked position and an unlocked position. Infigure 1 and3 thepawl members 20 are shown in the locked position. Infigure 3 that pawlmembers 20 are shown in the unlocked pawl by the interrupted lines. The locking mechanism operates symmetrically around theslot 15 and theactuator slide 16. Thelink arms 24 of the locking mechanism are connected to theactuator slide 16 via ahinge 29 and to lockingarms 22 via thehinge 28. - The
first spring wires 25 are mounted to thecasing 10 via fastening pin heads 26 and fastened to the link arm hinges 28, and thesecond spring wires 27 are mounted on thelink arms 24 and fastened to thehinge 29. - In
figure 3 theoperator arm 12 and theactuator slide 16 are shown in their three possible positions (two of the positions are indicated by interrupted lines.) In the position indicated by the uninterrupted lines the lock is the locking position. In the intermediate position the lock is locked but slightly open to achieve ventilation. When the position indicated with the interrupted lines with theoperator hinge 13 in the extreme position to the right and assume the lock is in the open position and the window can be opened without any substantial resistance. - In the second, locked position the
actuator slide 16 and thepawl members 20 are positioned at the ends ofslots actuator slide 16 is held in the first, unlocked position by thesecond spring wires 27 and a first dead point of the locking mechanism. Theactuator slide 16 is moved from the second, locked position to the third, intermediate position by moving theactuator slide 16 through said first dead point towards the opposite end of theslot 15. In the embodiment shown the first dead point is implemented as a combination of thesecond spring wires 27 mounted in thecutout 23 of thelink arms 24 and the shape of the lockingarms 22 and position of the first fastening/pivot pins 14. The position of thepawl members 20 is not affected by moving theactuator slide 16 between the second, locked position and the third, intermediate position. - In the third, intermediate position the
actuator slide 16 is positioned between the ends ofslot 15 as may be seen infigure 3 , without having moved the lockingarms 22 of the locking mechanism. - The
actuator slide 13 is held in the third, intermediate position by the first dead point and a second dead point established by thefirst spring wires 27. In the second, locked position and third intermediate position of theactuator slide 16 thefirst spring wires 27 hold thepawl members 20 in a locked position at the opposite ends of theslots 18 compared to the position of thepawl members 20 in the unlocked position (interrupted lines infigure 3 ). - Moving the
actuator slide 16 from the third, intermediate position to the first, unlocked position, said second dead point is passed and the lockingarms 22. In the first, unlocked position of theactuator slide 13 thefirst spring wires 25 hold thepawl members 20 in the unlocked position. - The second dead point is implemented by the
first spring wires 25 operating on thehinges 28. Thepawl members 20 are operating in conjunction with thehinges 28 and are implemented as an integrated part of the lockingarms 22 of the operating mechanism. - When the window is closed, the
pawl members 20 are urged to their locking position byguide surfaces 62 one the striking plate (thestriking plate 52 and the guide surfaces 62 will be described in greater detail below). The movement of thepawl members 20 is transmitted to theactuator slide 16 via the locking mechanism and theactuator slide 16 is pulled back from the first, unlocked position to the intermediate position. - In the third, intermediate position the
actuator slide 16 can be moved to the first, unlocked position as described above or moved to the second, locked position by passing the first dead point of the operating mechanism. -
Figures 6 to 10 show the lockingarm 22 in greater detail. The lockingarm 22 is preferably made from plate material, in particular high tensile steel plate material. The lockingarm 22 comprises a substantially straight portion that is provided at one end with anaperture 34 receiving the fastening/pivot pin 14 whilst the other end is bend over at abend 39 to form thepawl member 20. - The straight remainder of the locking
arm 22 is provided with anaperture 31 near thebend 39 for forming arim 32 that is used to form ahinge 28 to connect to thelink arm 24. - The
pawl member 20 is at an angle α of approximately 118° with the remainder of the lockingarms 22. The angle α can be anywhere between 115 and 120°. This range of angles has been found to give good results. - The outward surface at the tip of the
pawl member 20 is formed as anabutment surface 36 for abutment with a locking face of thestriking plate 50. Theabutment surface 36 is substantially parallel with thehinge pin 14. - The
pawl member 20 is provided withnarrow sides 38 that converge towards the tip of thepawl member 20 for facilitating entry of thepawl member 20 into theslot 51 of the striking plate 50 (figures 14-17 ). - The portion of the
pawl member 20 closest to thebend 39 is profiled to improve the resistance of thepawl member 20 to be bend over when a large force is applied to theabutment face 36. The profile can particularly be well recognized in the cross-sectional area infigure 7 . The profile comprises acentral protrusion 34 with retractedareas 35 at the short sides 38. In embodiment the profile can be reversed with it protruding parts near theshort sides 38 and the retracted part being placed centrally in thepawl member 20. -
