Abstract

A slider (3) operated lock has a pivot mounted latch (26) in a lock housing (2) with direct connection to the slider. The latch has three settings; fully locked, fully released and a trip setting, with the latch in an intermediate setting. A trip catch (18) is set independent to the latch and extends out of the lock and is released when the door/window is swung shut. This provides a direct release of the sprung (17) latch to move into the fully locked position.

Description

The invention relates to a drive rod lock for a against a frame movable wings with one in one Lock case movably arranged latch bolt, with a coupling the latch bolt with a drive rod Slider, wherein the latch bolt during a movement of the Driving rod from a bolt position in which the latch bolt with a run-on slope and an adjoining one Latch section protruding from the lock case, in an unlocking position located within the lock case is movable, with a spring element for Bias of the latch bolt out of the lock case, with a locking element for supporting the latch bolt in a trap position, in which the latch bolt in Essentially only with the run-up slope from the lock case protrudes, with the blocking element in one movement of the wing in the frame to release the movement the latch bolt from the latch position in the bolt position is held movable, and with one with the Locking element connected, from the movement of the wing against the frame controllable buttons.

Such espagnolette lock is for example off EP 0 798 436 A1. The latch bolt of the Espagnolette lock is longitudinally displaceable in the three positions guided and has a pocket for recording of the button. The button carries the trained as a locking nose Blocking element and has a release nose. In Trap position, the blocking element is based on the Lock case and thus holds the latch bolt in the Case position. If you press the latch bolt, for example by moving the sash against the frame, from the trap position into the lock case, slides the release tab on an edge of the lock case along and lifts the positive connection between the blocking element and the lock case. Simultaneously stops Fallenaushubhebel the locking element within the latch bolt. The latch bolt is then lifted by the latch lift lever pressed into the latch position. A trap reset lever is with the slider and thus with the Connecting rod and allows retraction of the Latch bolt.

In the unlocked position allows the latch bolt an unimpeded movement of the wing relative to the frame. In the case of the trap when swung away from the frame Wing becomes the latch bolt during the movement of the wing pressed against the frame in the lock case and snaps into the bolt position and with it for example, in a striking plate of the opposite Component. In latch position, the latch bolt is about 10 up to 15 mm further pushed out of the lock case and thus assumes the function of a well-known Bar.

A disadvantage of the known espagnolette lock, that it contains many components and therefore expensive to be finished. Furthermore, the guidance of the Fallenaushubhebels, the locking nose and the release nose with each other and compared to the lock case very tight tolerances and thus high production costs.

The invention is based on the problem of a drive rod lock of the type mentioned at the beginning, that it is very simple and inexpensive to be finished.

This problem is inventively achieved in that the latch bolt pivotally mounted in the lock case is and has a support arm that the button is independent from the movement of the latch bolt from the lock case is biased out and during a movement of the grand piano guided pressed against the frame in the lock case is and that the locking element when out of the lock case outstanding button the support arm of the trap supported latch bolt and the movement of the Support arm in the depressed into the lock case position of the button releases.

Leave through the swiveling bearing of the latch bolt forces from the slide without interposition of a Transfer the latch retracting lever. This leads to a reduction the components of the espagnolette lock according to the invention. Furthermore, the movement of the button is independent from the movement of the latch bolt. That's it not necessary, the movement of the button with the hub to control the latch bolt. This will also close Tolerances of the button, the latch bolt and the locking element avoided. The espagnolette lock according to the invention can therefore be manufactured particularly cost-effective.

A movement of the latch bolt located in the locked position without drive the drive rod can be according to a advantageous development of the invention simple Avoid placing the latch latch in the locked position abstützendes blocking element of the slider controllable is. Continue to be in befindlicher in bolt position Fallen latch acting in the unlocked position Forces absorbed by the espagnolette lock according to the invention. In a manipulation occurring forces are therefore kept away from the drive rod.

The well-known espagnolette lock tends to malfunction, for example, if you only briefly hold the wing against the Frame moves and pulls away. This can be the triggering nose release the movement of the latch bolt. Subsequently the latch bolt comes in from the frame pivoted wings in the bolt position. This can Damage to wing, frame and espagnolette lock to lead. A movement of the latch bolt in the Latch position not completely in the frame Wing can be according to another advantageous development simply avoid the invention when the button in the intended closing direction of the wing against the frame is offset from the latch bolt, so that when moving the wing against the frame first the latch bolt and only then the button with an opposite Component comes into contact. This design leads to a significant reduction in malfunction the espagnolette lock according to the invention.

An entanglement of the espagnolette lock according to the invention with a drive of the latch bolt and engaged Blocking element is easy to avoid when the slider engages at its with the latch latch standing area has a free area. By the free space of the slider is easy to make sure that first the blocking element from the trajectory of the latch bolt is moved and only afterwards the latch bolt is driven.

The separation of the movements of the latch bolt and the Tasters requires according to another advantageous development the invention a particularly low cost, if the lock case has two recesses, the latch bolt passing through one of the recesses and the button is guided by the other of the recesses.

The blocking element is designed according to another advantageous development of the invention particularly constructive easy, if the blocking element as a flat, in the sheet metal box pivotally mounted sheet metal part formed is.

The storage of the blocking element requires according to a another advantageous embodiment of the invention a particularly low structural complexity, if the blocking element Walls of the lockbox penetrating Having protrusions.

The blocking element can be easily by gravity in his blocking the movement of the latch bolt Move position when the blocking element at one end a storage in the lock case and with its other End of the latch bolt is supported in the locked position and in the intended mounting position horizontally in the lock case is arranged and in Endriegelstellung and in trap position by gravity loose on the latch bolt rests. This contributes to further reducing the number the components of the espagnolette lock according to the invention at.

To further reduce the number of components of the invention Espagnolette contributes to it, though the blocking element is made in one piece with the probe.

The button could, for example, as in the known Espagnolette lock from a lifting lever in its intended Able to be pressed. To further reduce the number of components of the espagnolette lock according to the invention It helps when a spring element the button in the outstanding position from the lock case biases.

The use of a Fallenaushubhebels as in the known Espagnolette lock can be changed according to another simply avoid an advantageous development of the invention if a spring element directly the latch bolt from the lock case pretensions.

FIG. 1 shows an espagnolette lock mounted in a wing 1 2 with a drive rod 3. The drive rod 3 can be in their longitudinal direction by means of a schematic illustrated main lock 4 and / or an electromotive Move drive 5. The wing is 2 pivotable against a frame 6 shown in Figure 2 stored. The drive rod 3 is under one on the wing 1 attached cuff 7 a lock case 8 arranged. The cuff 7 has two recesses 9, 10, wherein a first recess 9 for performing a latch bolt 11 is used while the other recess 10 a longitudinally displaceable button 12 leads. The latch bolt 11 has a bearing 13 in the lock case 8 and a coupling element 14. The coupling element 14 is connected to a recess 15 of a slider 16 in conjunction. The slider 16 is connected to the drive rod 3. The latch bolt 11 is by means of a spring element 17 against a biased to a locking element 18 supporting support arm 19. The button 12 is integral with the locking element 18 manufactured and is of a spring element 20 in the shown, protruding from the lock case 8 position biased. A blocking element 21 has a bearing 22 in the lock case 8 and lies on the latch bolt 11 on. In the lock case 8 arranged grooves serve to guide the button 12, the slider 16 and the blocking element 21.

The latch bolt 11 protrudes like the button 12 exclusively with a run-on slope 26 out of the lock case 8 out. A subsequent to the run-on slope 26 latch portion 27 with a constant rectangular cross-section is located inside the lock case 8. This indicates the trapping of the espagnolette lock 2.

In a movement against the illustrated in Figure 2 Frame 6 is from a strike plate 28 of the frame 6 first the latch bolt 11 against the force of the spring element 17 pressed into the lock box 8. At the same time removed the support arm 19 of the locking element 18. This indicates the unlocking position shown in Figure 2 of the espagnolette lock 2.

In a further movement of the wing 1 against the frame 6, finally, the button 12 of the frame 6 in pressed the lock case 8. This is the blocking element 18 moved out of the range of motion of the support arm 19 and the movement of the latch bolt 11 is released. Of the Fallen bolt 11 is then by the force of the spring element 17 initially on the illustrated in Figure 3 Trap position in the locking position shown in Figure 4 moved, if, as shown here, the position the recess 15 of the slider 16 relative to the coupling element 14 and thus the position of the drive rod 3 this allows. In this bar position is the latch bolt 11 both with the run-on slope 26 and with his latch section 27 outside the lock case. 8 Furthermore, it can be seen in FIG. 4 that the blocking element 21 starting from its position in FIG. 3 by gravity into the range of motion of the latch bolt 11 was moved. The blocking element 21 is now located on a projection 29 of the slider 16. A back press of the latch bolt 11 in the lock case 8 is prevented by the blocking element 21.

To unlock the espagnolette lock 2 is first to move the drive rod 3. It is the first Blocking element 21 of the projection 29 of the slider sixteenth pushed out of the range of movement of the latch bolt 11, without the latch bolt 11 is moved thereby.

For this purpose, the slider 16 in the region of the coupling element 14 a free area 30. In a further movement of Drive rod 3, the latch bolt 11 in the lock case 8 swung back, as shown in Figure 5 is. At a distance of the wing 1 from the frame 6th the button 12 jumps out of the lock case 8 again and thus moves the blocking element 18 in the in FIG 1 position shown. After a return movement of Drive rod 3 from the position of Figure 5 will be back reached the trap position shown in Figure 1.
