EP2143860A2 - Closure for windows or doors - Google Patents

Abstract

The lock has a face plate rail (2) covering a connecting rod (8), and a swing bolt fixedly supported around a pivoting axis. The swing bolt cooperates with the connection rod such that the connecting rod is swiveled out from a recess into the face plate rail in a direction of the swing bolt, and is returned into another direction, during displacement. Locking engagement elements are attached to the swing bolt at a frame. The swing bolt and the connection rod are connected by a knee lever mechanism, which comprises a lever.

Description

The invention relates to a closure for windows or doors according to the preamble of claim 1.

A closure according to the preamble of claim 1 is known from DE 4323341 A1 already known. For actuating the bolt, the bolt is provided with an opening into which the push member engages via a specially shaped driver. The eccentric arrangement of the opening thereby causes a pivoting movement of the bolt.

From the DE 4222629 A1 a closure is known in which the drive rod is coupled to a slider. The slider has a transverse to its direction of movement recess in which a driving pin is slidably disposed. The driving pin is slidably guided in a control cam in the lock case and in a groove in the pivot bolt. The arranged in the lock case cam has a pocket for receiving the driver in befindlichem in the closed position pivot bolt. If one tries to push back the locking bolt located in the closed position into the lock case, the driver located in the pocket of the control cam blocks its movement. Thus, the pivot bolt can be moved back exclusively via the drive of the drive rod in the open position. The drive of this espagnolette requires a lot of force to overcome the friction in the recess, the cam and the groove. Furthermore, as a result, the lock case is much wider than the pivot bolt.

From the DE 10359803 A1 Finally, a bolt control is known in which between the pivot bolt and the drive rod, a pinion is effective, which engages with a driver on the pivot bolt. The pivot bolt is designed as a two-armed lever whose remote from the locking hook end of the lever has a recess into which the driver engages. A pushing back of the pivot bar is to be made more difficult.

All vorgenanten embodiments have the disadvantage that the drives for the pivot bolt can muster a low torque. This is given in particular when the drive rod is to be driven by a key, since the applied via the key stroke as well as the force introduced into the closure are limited. The pivot bolt can therefore be used limited to use the wing to the frame or to overcome resistance to the pivoting movement. In addition, there is generally only a small space available, so that little space for over- or reductions is available.

The object of the invention is therefore to provide a closure which generates a high torque on the pivot bolt and thereby takes up a small space.

This object is achieved in a closure according to the preamble in that the pivot bolt and the drive rod are connected via a toggle mechanism. By this simple measure, a large force is generated at a comparatively small space. In addition, the embodiment is particularly simple by exclusively pivotable connection of the functional members. The pivot points and bearings can also be easily and with high precision produced, so that a low-backlash connection of the functional members is given.

It is also provided that the toggle mechanism comprises a lever through which the pivot bolt and the drive rod are drivingly connected and which is pivotally connected to the pivot bolt and the drive rod, wherein the pivot points of the lever relative to the displacement plane of the drive rod offset from the axis lie. The staggered arrangement of the pivot points causes on the one hand a certain initial torque of the pivot bolt. On the other hand it is achieved that the storage of the pivot bolt - relative to a parallel to the pivot axis extending housing edge - is arranged offset to the storage of the lever. The lever is passed by the drive rod to the storage of the pivot lever, so that the storage of the pivot lever can be designed significantly stronger and provided in the housing walls of the closure itself.

A further embodiment provides that the pivot points of the lever in the pivoted-back position on an approximately parallel to the direction of the Drive rod lying line, so that with a small adjustment movement and force of the drive rod already results in a comparatively large adjusting movement and - force of the pivot lever.

If the pivot bearing of the pivot bolt and a pivot point of the lever with respect to the displacement direction of the drive rod in an approximately perpendicular thereto extending line, a staggered arrangement of the pivot bearings can be achieved.

It is further provided that the pivot points of the lever are in the pivoted position on a lying approximately perpendicular to the direction of displacement of the drive rod line. As a result, a pushing back of the pivot bolt is prevented from the locking position. The introduction of force via the pivot bolt results in a force component acting essentially at right angles on the drive rod, which, however, can not effect an actuating movement of the drive rod.

It is particularly advantageous for the closure when the pivot bolt has a cross-section tapered bolt head whose flanks cooperate with a locking edge of the locking engagement for pulling the wing to the frame. The high torque, particularly in the last section of the pivotal movement, can therefore allow optimum relative alignment of the frame and the wing. In addition, due to the high torque when closing it back, it can be essential that a slightly warped wing can still be easily unlocked.

If the pivot bolt is seated in a secondary lock housing of a multi-point lock, can be arranged several pivot bolt. The torque-reduced design on the key-trajectory allows a plurality of closures, which are therefore difficult to overcome, to be provided.

A development of this embodiment provides that the drive rod is designed as a drive rod connection slide, which is slidably mounted in the secondary lock housing, so that each pivot bolt can be assigned to a separate housing of the secondary lock and can be provided in any number of the closure.

The espagnolette with the reference numeral 1 has a attached to a faceplate 2 main lock 3. Above the same wearing the faceplate 2 an additional or secondary lock 4. An identical sub-lock and possibly other secondary locks are located below the main lock 3 and above the secondary lock 4, however, these are not shown here. The espagnolette lock 1 thus forms a closure designed as a multi-point lock.

The main lock 3 has a latch 5, which is retractable by means of a nut 6 rotatably mounted in the main lock 3. Below this, the main lock 3 receives a profile cylinder 7. When key operation exiting from the main lock 3 drive rod 8 is displaced either in one direction or the other, depending on the direction of rotation of the cam of the profile cylinder. 7

In detail, the secondary lock 4 is composed of a right angle to the face-plate 2 aligned, connected to this lock bottom 9 (Fig. Fig. 3 ) and a lock cover 10 arranged parallel thereto.

From the FIGS. 3 to 6 It can be seen that the secondary lock 4 has a movable in the longitudinal direction of the secondary lock housing 14 espagnolette slide 15. Its rear end runs along a lock rear wall 16. The lower end 17 of the espagnolette 15 extends to the faceplate 2, not shown here, where it has a recess 13 extending at right angles thereto, into which the drive rod 8 is inserted with an angled portion for the purpose of driving connection.

As in connection with the Fig. 2 it can be seen, a pivot bolt 18 is provided below the pivot bolt 12. The pivot bolt 18 is connected by means of a pivot bearing 19 with the secondary lock housing 14, which consists of a bore 20 of a pivot bolt 18 passing through. While the pivot bolt 18 is thereby fixedly secured in the secondary lock housing 14, a lever 21 by two pivot points 22, 23 forming pivot bearings with the pivot bolt 18 and the espagnolette 15 is connected.

In this case, the pivot point 23 is associated with the espagnolette 15 and is carried along with this in a movement of the drive rod 8, as from a comparison of FIGS. 3 and 4 seen. At a displacement of the drive rod 8 and thus the espagnolette 15 from the in the Fig. 3 illustrated open position in the intermediate position after the Fig. 4 For example, the espagnolette 15 is displaced by a travel 24 and the pivot point 22 by a distance resulting from the sum of the dimensions 25 and 26. Since the espagnolette 15 is moved along the arrow, it can be seen that the pivot points 22, 23 of the lever 21 in the pivoted-back position of the pivot bolt 18 on a lying approximately parallel to the direction 27 of the drive rod 8 and the espagnolette 15 line 28 lie.

Due to the stationary mounting of the pivot bolt 18, a torque is effective on the pivot bolt 18 and the line 30 which connects the pivot point 22 with the pivot bearing 19 is also pivoted. From the illustration to Fig. 3 It can be seen that the pivot bearing 19 of the pivot bolt 18 and the pivot point 22 of the lever 21 with respect to the direction of displacement 27 of the drive rod 8 lie in an approximately perpendicular thereto extending line 30. The pivot bolt 18 and the espagnolette 15 form together with the lever 21 thereby a toggle mechanism, in which the introduction of force via the lever 21, starting from the open position initially takes place almost at right angles.

Accordingly, a maximum torque results on the pivot bolt 18, which can still be influenced substantially by the distance of the pivot point 22 from the pivot bearing 19 and the displacement force of the drive rod 8 or of the drive rod connection slide 15.

Starting from the representation after the Fig. 3 It can be seen that the toggle mechanism is designed so that the pivot points 22, 23 of the lever 21 with respect to the along the direction of displacement 27 extending displacement plane of the espagnolette 8 are offset from the pivot bearing 19. The storage of the pivot bolt 18 is thereby - relative to a parallel to the pivot bearing 19 extending and, for example, formed by the face plate housing edge - arranged to support the lever 21. The lever 21 is guided by the drive rod 8 and the espagnolette 15 on the pivot bearing 19 of the pivot lever 18. As a result, the pivot bearing 19 can be significantly more powerful and made simpler to manufacture in the lock bottom 9 and the lock cover 10.

In a further displacement of the espagnolette 15, the result in the FIGS. 5 and 6 shown positions. The lever 21 is displaced by the displacement of the pivot point 22 on the one hand and the forced pivotal movement of the pivot point 23 about the pivot bearing 19 so that the line 28 is now approximately perpendicular to the direction 27, while the line 30 occupies a nearly parallel position. In the intermediate position after Fig. 5 the line 30 still takes an angle 31 with respect to the direction of displacement 27, which is greater than 90 °. In the Verschiebeendstellung the drive rod 8 and the espagnolette 15, the angle 31 is smaller than 90 °. As a result, a pushing back of the pivot bolt 18 without destroying the mechanism is not possible, so that a manipulation of the closure directed thereto can not succeed.

Due to the use of the toggle mechanism results in a torque curve, which in the Fig. 7 is shown. The curve 35 shows the force acting on the pivot bolt 18 torque as a function of the angle of rotation, which is effected at a constant force on the drive rod 8 and the espagnolette 15.

The curve 36 shows for comparison a torque curve with the same driving rod actuating force, as in the curve 35, in a device known from the prior art. It can be seen that at the beginning of the pivoting movement in the device according to the prior art, a higher torque is reached, which, however, falls when reaching a pivot angle 37 and fluctuates at a lower level.

In the case of the closure created by the use of the toggle mechanism, the moment 39 effective on the pivot bolt 18 is initially lower, but increases with increasing pivot angle 38. This results in the pivot bolt 18, a higher torque 39 in the area in which the pivot bolt 18 is immersed in the frame-side strike plate, while in the known prior art closure the effective torque on the pivot bolt 18 at the same operating force-significantly decreases.

In the FIGS. 3 to 6 the pivot bolt 18 is shown slightly schematically. In the Fig. 8 is the pivot bolt in a single view and enlarged visible. The pivot bolt 18 is equipped at its one flank with a Schwenkriegelmaul 41, which in zurückgeschlossenem pivot bolt 18 after Fig. 3 within the auxiliary lock 4 lies. Of the two mutually parallel broad side surfaces 42 of the pivot bolt 18 go outside the Schwenkriegelmaul 41 comprehensive, only to the pivot bolt tip 43 sloping facet surfaces or flanks 44. These drop to the peripheral edge 45 evenly, so that the pivot bolt 18 has a tapered cross-section bolt head 49. The two opposite facet surfaces or flanks 44 serve in cooperation with a striking plate opening to a uniform suit of a possibly discarded wing to the frame. In order to avoid sharp edges in the region of the Schwenkriegelmauls 41, the two facet surfaces 44 are provided with a sliding surface 46. This runs parallel to the castle ceiling 10 and the castle floor. 9

For the passage of the pivot pin 20 of the pivot bolt 18 forms a bore 47. This is in the area of a broadside surface 42 of a towering this Collar 48 taken. The latter slides on the inner surface of the lock cover 10 and serves as a support.
