Lock assembly for windows or doors

The invention relates to a closing assembly for doors and / or windows, comprising a handle and a bolt that can be operated thereby.

Such closing assemblies are known. In a first, simple embodiment, the handle forms a directly rotatable assembly with the bolt, without the presence of a locking means, such as a lock. In the case of ordinary glass in the door or the window, such a handle can easily be operated from outside by unauthorized persons after breaking the glass. When burglar-resistant glass is used, a hole can be drilled through the wood of the door or window wing to, for example, grip and turn the handle with a stiff wire.

In a second known embodiment, the handle 15 is provided with a safety device in the form of a slide or push button, which must be shifted or pressed before the handle can be turned. However, this protection does not appear to be a significant obstacle in both of the aforementioned situations. In the case of a drilled hole, it appears that the slide or push button can be operated with a second rigid wire.

The use of a pull button instead of a push button could complicate unauthorized operation, but the operation then becomes more difficult for the authorized user, since both hands will be required for this. Also known is the use of a rotary knob instead of a push button, which rotary knob you should use with your thumb 1024278 = I Η

When the lips 19af 19b touch the faces 46, the user will feel that, and know that the following movement can be started, following movement in the Z direction of the lips 19a, 19b, namely by moving in the direction Y push, with the thumb, against the button 22, to move it into the hole 28 in the direction Y, until the situation shown in Figure 4B is reached. The pin 21 has come against an end of the longitudinal hole 39, and at the same time the button 22 has also reached the upper limit of the hole 28. As a result of the engagement of the pin 21 in the hole 32, the pull strip 30 is also displaced, guiding it on curved surface 45 and plane 47. The movement in the direction Y of the end of the pull strip provided with the hole 32 30 is converted into a movement in the direction Z of the locking part 14 and thus the locking pin 34, which is thereby pulled out of the locking hole 54. Herewith the crank housing 8 is only rotatably connected to the housing 9, and the user can rotate the crank arm 7 and therewith the crank housing 8 to pivot an axis of rotation parallel to the direction Z, to pivot the bolt 6 downwards into slot 10 about the window or door.

In a closing process, when the crank arm 7 is swung back, the locking pin 34 will run over the surface of the cupboard wall 9a, and once arrived before the locking hole 54 will click into the hole under the action of the spring 15. Then rotation of the crank arm is prevented again.

If only one of the buttons 26a, b is pressed, or neither is pressed, the non-pressed button on the respective lip 19a, b provided with step 43a, b will be caught by shifting in the direction Y trajectory lying hook-shaped step 44a, b. Operation of the crank arm 7 will only be possible if all buttons are operated in the correct manner and in the correct order.
