State of the art

A device for detecting a window or door leaf in the desired position is the patent, for example DE 19516588 refer to. This patent describes a locking device for windows, doors and the like with a fixed frame and a pivotally connected thereto sheet. The actual locking device is disposed in a lateral portion of the blade and includes a slidable rod having a handle at its free end. The main part of the displaceable rod is slidably mounted on the bottom of a guide strip whose section has the shape of the letter U and which is fixedly arranged in the sheet. A part of the displaceable rod is provided on the surface facing away from the bottom of the guide bar surface with spaced flat cams. A longitudinally fixed, transversely flexible movable rack rests with their counter cams on these flat cam and a portion of its length is provided with a cross-toothing for connection to a corresponding cross-toothing on a slider. The slider is mounted in the guide rail by means of two grooves, wherein guide projections, which are formed on the inner surface of the guide bar, engage in these grooves. One strut is to the slider at one Pins pivotally connected, whose other end is arranged in a stanchion attached to the frame swaying. One attachment piece is attached to each of the ends of the bottom of the guide rail. Each of the extensions forms an end stop for delimiting the longitudinal movement of the slider, as well as an upper support for the rack. Depending on a spring for pressing the rack on the sliding rod is arranged in each of the attachments.

When a window or door leaf is to be opened into a desired position, the displaceable rod is pushed by means of the handle, with their flat cams emerge from the engagement with the counter cams on the toothed bar, and the counter cams pass between the flat cams. Under the action of the spring in the attachment pieces the rack reaches from the locking position in a free position. As a result, the cross teeth of the rack come out of engagement with the counter teeth of the slider, which is thereby released for the longitudinal movement on the guide projections of the guide rail, and the window or door leaf can be opened in the desired position, wherein the strut is pivoted simultaneously. By pushing back the sliding rod, the flat cam are guided under the counter cam of the rack, which is thereby removed from the sliding rod and the flat teeth enters the counter teeth of the slider and secures the window or door leaf in the desired position.

A disadvantage of the device consists in the fact that the functional components of the device are arranged so that in the case of an adaptation of the dimensions of the entire device to the normal size of the groove for the fitting structure remains a relatively small amount for the teeth of the slider and the rack , As a result of the small teeth, the holding force acting between the slider and the toothed bar is relatively low. In order to secure a sufficient holding force between the slider and the rack, the slider must be relatively long. As a result of the low holding force between the slider and the rack must be the point of application of the holding force as far as possible from the hinges, especially in the case of larger leaves, so a relatively long strut must be used to connect the slider with the window frame. These facts significantly affect the versatility of the locking device.

At the end of the assembly, we fasten the connecting element 51 to the frame 52 and the strut 111 by means of the connecting bolt 112 to the connecting element 51 . After the first partial rotation of the control lever 49 in the determined for the determination of the mechanism position, the overhang projections 92 , 93 of the adjustable traction means 90 in one of the possible positions with respect to the gentle elevations 79, 80 of the tooth comb 75 in response thereto in which direction the actuating cable 123 moves during the partial rotation of the control lever 49 .

The protective strip 94 is made sufficiently long so that it can be adapted during assembly in the mounting slot 119 in the sheet 1 by cutting to the required length and so that it can protect all subsequent sets.

The assembly of the modified parts takes place during the machine assembly in three steps, namely placing the modified strut 133 with the modified support opening 134 on the modified head bolt 125 in a parallel with the other, already assembled parts of the locking device position ( Fig. 34, 35th ) and the subsequent partial rotation of the modified strut 133 in the position which is intended for the manual placement of its other end on the connecting bolt 112 on the frame 52 of the window sheet 1 .

The second embodiment of the locking device according to the invention functions as follows:

If the window sheet 1 is closed, the teeth 3 of the dental ridge 75 are due to the action of the compression spring 88 to the comb 75 in engagement with the mating teeth 113 of the tooth pusher 106, and thereby the movement of the tooth pusher 106 is avoided. When the sheet 1 is to be opened, the control lever 49 is rotated, whereby, for example, an unillustrated pinion is rotated so that the Betätigungszugmittel 123 and the adjustable traction means 90 by means of a comb, not shown, longitudinally displaced from the secured position of the sheet 1 in the unlocked position be in the fact that the overhang projections 92 , 93 due to the elongated displacement of the adjustable traction means 15 from the position in which they were stored in the gaps between the gentle elevations 79 , 80 of the tooth comb 75 , in the position they are brought into contact with the highest surfaces of the gentle elevations 79 , 80 of the tooth comb 75 are pushed. Thus, the tooth comb 75 is urged against the force of the compression spring 88 away from the tooth slide 106 , wherein the teeth 3 of the tooth comb 75 from the Engage with the mating teeth 113 of the toothed slide 106 , whereby it is released.

The sheet 1 is swung out during the subsequent manual opening of the sheet 1 on the hanger 74 , wherein the strut 111 is pivoted out on the connecting element 51 and is rotated on the connecting bolt 112 and the head bolt 109 is displaced with the toothed slider 106 on the protective strip 94 . The toothed slide 106 is pushed during this movement on the protective strip 94 to the position of the eventual maximum opening of the sheet 1 . When the sheet 1 is opened to the desired position, the control lever 49 is rotated back, wherein the Betätigungszugmittel 123 is pushed back and the adjustable traction means 90 is moved back to the original position for securing the toothed slide 106 back. In this case, the adjustable traction means 90 is pushed between the side walls 76 , 77 of the tooth comb 75 . The overhang projections 92 , 93 fall from the position in which they were in contact with the gentle elevations 79 , 80 of the tooth comb 75 , in the gaps between these gentle elevations 79 , 80. Thus, the compression spring 88 are released, they move the tooth comb 75 until it reaches with its teeth 3 in engagement with counter teeth 113 of the toothed slide 106 . Thus, the toothed slider 106 is locked and held the sheet 1 in the set position.
