Description

The invention relates to a tilt lock device for Tilt and turn windows and doors according to the generic term of Claim 1.

Such a tilt lock device is from DE 36 27 043 C1 known. The task of such a rocker bar device tion generally consists of ensuring the closure function of the window or the door and on the other hand the on "lock" the desired switching function, to enable "rotate" and "tilt". Beyond that especially in the tilted position of the window or door leaf an effective prevention of incorrect switching purposes Accident prevention on the one hand and an anti-lift device for To accomplish the purpose of burglary protection on the other hand. Furthermore, a secure system on the frame of the tilted To strive for wing to undesirable rattle, z. B. by Avoid the influence of wind.

The central part of such a tilt lock device is one Bending bar spring. Therefore, the known toggle latch device first explained in more detail based on the bending rod spring become.  

For the purpose of securing the wing, the known rocker bar device a bending rod spring Application in a longitudinal slot in a faceplate in With respect to the faceplate is stationary. The bending bar spring has a U-shape in plan view, the Bending rod spring itself a rectangular cross section has and in the longitudinal slot of the faceplate such is recorded that the rectangular cross section transverse to Level of the faceplate is upright. The bending bar spring protrudes the faceplate by at most 1 mm, at least 2 mm of the height of the bending rod spring in the longitudinal slot of the Face plate is added. The longitudinal slot has in the upper straight to parallel to each other up to medium length range running surfaces on which the outer surfaces of the Apply the bending rod spring. In the lower length range of the Longitudinal slots of the faceplate are bulges arranged. The bending rod spring fits in a form-fitting manner by means of their two legs projecting over the faceplate molded into the back of a swivel tab, parallel grooves.

In that, represent the closed position of the wing the switch position in which one by means of a hand lever drivable drive rod and the one with it Hinge pin connected swivel bracket in the faceplate all the way is pushed upwards, the legs of the bending rod stand spring at least almost along the entire length of the swivel bracket with their longitudinal grooves in holding and guiding engagement. In the middle switching position of the swivel bracket extends the Guiding engagement between the legs of the bending spring and the longitudinal grooves of the swivel bracket over more than that half length. The legs serve as a parallel guide for the swivel bracket. The drive rod is in the lower Switched position transferred, so the two legs of the Bending rod spring only in the one adjacent to the bearing journal  Length range of the swivel bracket with its longitudinal grooves in the form conclusive intervention. Is by tilting the wing now the swivel tab from its parallel position The faceplate swivels, so there is an elastic Deformation on the two legs of the bending rod spring, the ends of the two limbs of the flexible rod spring, which follow the pivoting movement of the pivoting tab, in immerse the extensions. After all, are at the bottom Protruding bumps at the end of the faceplate slot arranged to ensure that the free ends of the both legs of the flexible rod spring again and again in can return to their normal rest position as soon as the Swivel bracket to take their parallel position to the faceplate is looking for. To pinch the bending rod spring in the area of Preventing the bearing journal are several mm thick Faceplate comply with relatively tight tolerances, which at such, preferably by means of stamping technology sheet metal to be produced requires considerable use of tools.

It may be due to the relatively strong reset due to the bending rod spring in the longitudinal grooves of the swivel bracket heavy wear in the area of the bearing journal to lead. The bending rod spring can also be in the area of Wedge humps, causing the suspension behavior due to plastic deformation of the spring is permanently disturbed. The functionality can be disadvantageous due to the deformation impact. Furthermore, the abrasion dirty the door or Window frames. Finally act from the bending rod spring resulting noises disturbing during the tipping process.

A particular disadvantage is also due to the fact that the known tilt lock device only the switching functions in the order:

Close wings,
Turn wings,
Tilt the wing

and back allows, so the lever position of the hand lever on Window is mandatory because it is the well-known Bending rod spring only allowed in the lower area Bulges to be provided, and the swivel tab only on the Ends of the bending rod spring due to the groove guide in the Swivel bracket is pivotable.

However, due to increasing globalization - especially in the Anglo-Saxon countries - the so-called tilt before turn - short tbt switching sequence is desired, namely:

Close wings,
Tilt wings,
Turn wings.

This cannot with the known toggle latch device be solved satisfactorily.

Another toggle device is from DE 42 03 909 A1 known. Via a bearing designed as a riveted joint a pivot part is connected to a drive rod. The bottom of this swivel part lies on a faceplate rail and covered with two walls in the Tilt open position at its lower end a latch that designed as an eccentric pin and on a locking plate is attached. The eccentric pin is from the walls of the Swivel part included when the drive rod in the uppermost position, which represents the closed position, is moved.

The swivel part has one in the area of the bearing journal Backdrop approach that fits into one, about the width of the Longitudinal slit of the faceplate engages, one for pivoting the leg part  Expansion is planned. The swivel part points to his on the top end face with which the Support swivel part against a spring element which strives is to align the swivel part parallel to the faceplate. This spring element forms an elastic material existing full body vulcanized to a support part, the is riveted to the connecting rod with the drive rod so that the required adhesion between swivel part and Support part is reached. The support part forms with the Spring element is an integral component that connects to the faceplate connected is. However, it has been shown that such Uniqueness does not have the desired durability. The spring material quickly delaminates from the support part, causing the function is completely lost. In addition, that can delaminated material prevent safe closing, because it - following gravity - down into the Closing area falls.

In addition, this tilt lock device can not used satisfactorily for a tbt circuit become.

But there is a need for a safely functioning one Toggle bolt device of the type described, which flexible for both the first and the second of the described switching sequences can be used.

In the following, the same components are replaced with the same Reference numerals.

From Fig. 1 it can be seen that the rocker bar device 1 sits in the region of the lower frame corner 3 on the lower frame spar 4 and the wing spar 8 . It consists of a, secured to the frame member 4 Kippriegelplatte 7, to the central region two webs bolt member 5 a, 5 b and having a latch member pocket sixteenth The mechanically driven part of the rocker bar device by means of a drive rod 12 is assigned to the upright wing spar 8 . A faceplate 15 serves for the axial guidance of a drive rod 12 , which can be actuated by means of a lever 30 and is shown in FIGS . 11 and 13 and to which a bearing journal 11 is fastened, which passes through a longitudinal slot 14 arranged in the faceplate 15 . On the side facing the upright frame member 4 , the bearing journal 11 carries a pivoting bracket 13 which is pivotally mounted about the latter and which has a locking member 10 in the form of a cranked, integral extension, at its lower end. The bearing pin 11 has a locking pin 31 on the side of the faceplate 15 facing away from the drive rod 12 , which engages in the uppermost switching position between two locking bars 32 arranged in the upper region of the toggle plate 7 and thus secures the locking position of the wing 2 . In the middle switching position with respect to the longitudinal slot 14 , as shown in FIG. 2b, the locking member 10 engages in the locking member pocket 16 on the one hand and on the other hand the locking pin 31 is no longer locked by the two locking webs 32 , that is to say the wing can be tilted.

The swivel bracket 13 also has a driver 18 which - as can be seen in particular from FIGS. 2a and 2b - is operatively connected to a spring element 17 via an opening 26 . The outer contour 23 of the spring element 17 has - seen in plan view - an arched structure which is generally designated by the reference numeral 24 . As can also be clearly seen from FIG. 3, the spring element 17 has two arches 241 and 242 arranged opposite one another , which are designed as curved extensions 27 a and 27 b, by means of which the spring element 17 is guided in a longitudinally displaceable manner in the longitudinal slot 14 of the faceplate 15 . By means of a curved extension 27 a, the bearing pin 11 engages in the swivel bracket 13 , which thus causes a direct, form-fitting restraint of the spring element 17 with the bearing journal 11 , which serves as a swivel axis for the swivel bracket 13 . The spring element 17 is thus guided in the longitudinal slot 14 axially of the movement of the drive rod 12 - with which the desired switching position is set - so that it can be carried along and is held between the drive rod 12 on the one hand and the swivel bracket 13 on the other hand. As can be seen from the figures, the longitudinal slot 14 has a bulge 19 a and 19 b on its two longitudinal edges 14 a and 14 b. According to the stop of the wing (right or left), the faceplate 15 can also have only one of the bulges 19 a or 19 b. The bulges 19 a and 19 b are arranged in the longitudinal slot 14 at the point at which tilting is desired. When tilting the driver 18 pivots the pivotal bracket 13 to the central region of the bogigen structure 24 in the direction of the bulge 19 a, since the locking member of the swivel plate 10 engages 13 in the latch member pocket 16, and therefore relative to the face plate 15, the drive rod 12 and Kippriegelplatte 7 for a limited swivel range can be deflected. The swivel bracket is only released for this movement in this position.

In Fig. 4a, a first embodiment of the spring element 17 is shown in the untensioned position. The spring element 17 has a slot 25 in the center. As shown in FIG. 4b, only the part facing the bulge is deflected by the driver 18 .

A second exemplary embodiment of the spring element 17 for larger spring forces is shown in FIG. 5. The driver 18 is completely enclosed here by the spring element 17 . This ensures that the entire arched structure 24 participates in the suspension process.

In Fig. 6, a third embodiment of the Federele element 17 is shown, in which - in particular from Fig. 6c - the cross section is L-shaped, with an L-leg on the top of the face plate 15 between this and the pivot bracket 13 is arranged , which significantly counteracts wear if the spring element consists of a low-friction polymer material.

The outer contour of the spring element 17 can be closed all the way along its outer contour 23 or, as shown in FIGS. 7 and 8, be interrupted on one side, the bearing pin 11 penetrating the remaining arc 241 . The arched structure 23 of the spring element 17 according to FIG. 7 runs out in the region of the arch 242 in two legs 244 which rest on the longitudinal edges 14 a and 14 b of the inside of the longitudinal slot with their guide surfaces 244 a, 244 b pointing outwards.

The spring element 17 of a sixth embodiment shown in FIG. 8 extends in the region of the interruption of the arched structure 24 with a further arch 243 adjoining the arch 242 . Both the opposite outer lines of the arch 242 and that of the arch 243 are tangent to the longitudinal edges 14 a and 14 b of the longitudinal slot 14 of the faceplate 15 .

To adjust the suspension properties of the spring element 17 and / or the improvement of the system, the cross section of the spring element 17 can be largely rectangular cross section 28 a as in FIG. 9a, round cross section 28 b according to FIG. 9b and oval cross section 28 c according to FIG. 9c or, as above and described in detail in Fig. 9d L-shaped cross section 28, having d. Combinations of the above cross section are also possible.

The spring element 17 can with stiffening, encircling embedments 29 - z. B. of aramid - be provided, as indicated in Fig. 9a.

The longitudinal edges 14 a and 14 b of the longitudinal slot 14 of the faceplate 15 are, as can be seen from FIGS . 9a to 9d, designed to correspond to the cross section of the spring element 17 .

The configurations described above make it possible to achieve the desired spring behavior in a wide range. Furthermore, by forming the longitudinal edges 14 a and 14 b of the longitudinal slot 14 in connection with the corresponding design of the arches 241 , 242 , 243 and the legs 244, an optimal guiding behavior can be achieved. Esp. If the interrupted shape is selected, additional cutouts for mounting the spring element 17 can be dispensed with, since the mounting is achieved in a particularly simple manner by pushing it into the tilting position of the rocker bar device marked with K.

The switching functions will now be described in a diagram opposite. In Fig. 10, the three switching position of a lever 30 and in Fig. 11, the corresponding positions of the swivel bracket 13 and the associated spring member 17 of the toggle device of the normal switching sequence are shown schematically. In the closed position labeled V, the lever 30 is in the downwardly pivoted position. The lever is connected to the rocker bar device via a conventional — and therefore not shown — linkage, which acts axially displaceably on the drive rod. In this position, as shown in FIG. 11, the swivel tab is in the upper position representing the closed position at the upper end of the longitudinal slot 14 of the faceplate 15 . As described above, the locking pin 31 rests between the two locking webs 32 of the rocker bar plate 7 .

If the lever 30 is pivoted 90 ° counterclockwise, the rotational position designated D is reached, in which the wing 2 can be rotated about its pivot axis. The rotational movement is transmitted via the non-illustrated linkage on the drive rod and the pivot tab reacted 13 in addition to the, the bearing pin 11 engages around the spring element 17 in a medium with respect to the longitudinal slot 14 position axially, the closure pin has left 32 the area of the two closure webs 32 , so that the locking is released and an unimpeded turning process of the wing about its fishing axis is possible.

If the lever 30 is pivoted through a further 90 ° counterclockwise, the tilting position marked with K is reached. As described above, the rotary movement acts on the swivel bracket 13 and the spring element 17 in such a way that it reaches the lower end of the longitudinal slot 14 . The locking member 10 engages - as described above - between the toggle bolt-side locking member webs 5 a and 5 b. When tilting, the locking member 10 rests on one of the locking member webs 5 a, 5 b and is pivoted about the axis of the bearing pin 11 . The longitudinal slot 14 has the bulges 19 a and 19 b in this area, so that when the wing 2 is tilted, the swivel bracket is pivotally supported on one of the locking member webs 5 a, 5 b against the spring element 17 deformed by the driver 18 , the Driver 18 surrounding area of the spring element 17 is deflected and immersed in one of the bulges 19 a, 19 b. The wing rests against the lower frame corner 3 against the spring force of the spring element.

FIG. 12 shows the so-called tbt switching sequence of the lever 30 and FIG. 13 shows the corresponding positions of the swivel bracket 13 and the spring element 17 . The closed position marked with V is the same as that described above.

If the lever 30 is pivoted 90 ° counterclockwise from the lower closed position, the tilt position is set. The pivoting movement acts as described above on the swivel bracket 13 and the spring element 17 in such a way that it reaches the central region of the longitudinal slot 14 , the locking pin 31 having left the region of the two locking webs 32 , so that the locking is released and an unimpeded tipping process of the wing he follows. The locking member 10 engages in the locking bar-side locking member webs 5 a and 5 b, which are now arranged in the central region of the locking bar plate. The longitudinal slot 14 has the bulges 19 a and 19 b in the central area, so that when the wing 2 is tilted, the swivel bracket 17 is supported with the locking member 10 on one of the locking member webs 5 a, 5 b against the spring element deformed by the driver 18 17 is pivoted, the area surrounding the driver 18 of the spring element 17 being immersed in one of the bulges 19 a, 19 b. The wing bears against the lower frame corner 3 against the applied spring force.

If the lever 30 is pivoted a further 90 ° counterclockwise, the rotational position is now reached in which the wing 2 can be rotated about its pivot axis. The swivel movement is converted into an axially acting movement and the swivel bracket 13, together with the spring element 17 encompassing the bearing pin 11, is axially displaced into a lower position with respect to the longitudinal slot 14 . The locking member 10 thereby leaves the locking member pocket 16 which houses the locking member webs 5 a and 5 b. The wing 2 is now freely rotatable about its pivot axis.
