Description

in DK 171561 B1

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a latching mechanism for control rods for windows, doors or similar structures designed for optional right and left mounting, in particular by hinged rod hinges for turntable wing. It thus relates to such locking mechanisms, which consist of two sliding wedges located at a predetermined distance, which can be displaced linearly by means of an operating rod, e.g. along a guide rail, as well as of two predetermined, substantially fixed counter wedges, which may engage with the firing wedges, in which both the firing wedges and counter wedges, in addition to their wedge surfaces, are also formed with locking flanks extending parallel to the firing wedges. shear direction and is arranged on two lateral relative to each other parallel-displaced pieces, with the wedge faces of the sliding wedges 15 and the counter-wedges, respectively, facing in the same direction, but mutually opposite.

A latching device of this kind is known from DE-A-3,039,406. The latching mechanism known from this is designed so that not only the two sliding wedges must be individually secured 20 to the sliding rod which is slidably guided along a door rail or window frame, but also a bolt as a third function element must be attached to the slider.

The known system is arranged so that the engagement of the sliding wedges with the corresponding counter wedges ceases when the control rod which displaces the sliding wedges is switched from its side suspension position to the closing position.

Thus, in the closing position of the control rod, the door leaf or window frame can only be locked relative to the hinge rod by means of the extra bolt and the interlocking contact surfaces of this hinge rod, while the sliding wedges and counter wedges are no longer operable.

When the slider is switched from the side suspension position to the closing position, the sliding wedges exit from engagement with the slots already at a time when the bolt has not more than just begun to penetrate between the associated contact surfaces, but without yet being in contact with them.

The object of the invention is to eliminate the disadvantages of the known locking mechanisms. It is therefore the object of the invention to provide a latching mechanism of the kind mentioned in the first, which not only allows almost equal retraction sections for right and left mounting of windows and doors, but also at minimal installation space enables a simplified manufacture of the thus provided fittings, in particular, the hinge rod systems for pivot windows and pivot doors.

This object is achieved by a latching mechanism which is characterized by the characterizing part of claim 1.

A locking mechanism constructed in this way has the advantage that no additional slider is required on the control rod, but that a double locking of the hinge rod can be provided by only the two sliding wedges, and this locking becomes fully effective already when the control rod is displaced. from its flipped position to its side suspension position and remains uninterrupted even when the drive bar is switched from its side suspension position to its closing position.

In this embodiment, a locking mechanism is provided in which, without limitation of all the usual coupling functions of a single-handed 25 swivel bracket, only an installation length of 60 mm is required. In this way it is achieved that the locking mechanism according to the invention can easily be applied to even the smallest, in practice, conventional hinging systems.

Furthermore, according to claim 2, each sliding wedge can project, at least with its wedge-forming ends, beyond the adjacent longitudinal surface of the frame, and the locking surface adjacent to each wedge-point of each sliding wedge lies parallel to the outside of said longitudinal surface of the frame.

According to claim 3, it is furthermore advantageous according to the invention 35 that the two counter wedges and the two associated auxiliary pieces sit at the longitudinal edges of each other on the plate, each counter wedge being at the longitudinal edge opposite to the corresponding auxiliary piece. .

Where, in addition to the counter wedges, the actuating rod of a locking mechanism according to the invention also linearly displaces or switches a lock located at the end of the guide rail, a further suitable measure may consist of the lock together with its locking bars or one provided with such the locking fork sits on a slider% close to the counter wedges and is constructively joined thereto, and the slider is firmly connected to the control rod via the guide and fastening pieces (44, 45).

This embodiment is advantageous in that the lock engages the engagement surfaces of the hinge rod at an early stage, namely when the control rod is shifted from its suspension or folding position to its side suspension position, and then in this engagement also remains during the further displacement. to the closing position.

According to claim 5, it is desirable that the spaced wedges located one after the other on the slider are also designed so that their lateral locking surfaces are mutually spaced apart from the distance between the outward locking flanges of the hinge rod's sliding bars. .

In one embodiment of the locking mechanism according to the invention, the slider has approximately in the middle between the guide and fastening pieces an opening which, at a certain coupling position of the operating rod, is located next to a recess bore for a fastening screw.

In this embodiment, a particularly stable attachment of the guide rail to the wing is achieved in the installation area of the locking mechanism.

According to claim 6, this fastening can be improved by having the slider on its underside a recess located on each side of the opening 35, the length of which is adjusted to the maximum sliding distance of the slider. In this case, the place formed by the countersink bore on the guide rail can be provided with an imprinted neck which concentrically surrounds the countersink bore and provides a substantial stiffening of the part of the guide rail.

Finally, according to a further embodiment of the locking mechanism according to the invention, the slider in the region of the locking branches or the locking fork, respectively, can be provided with an opening as a viewing opening for observing a coupling in engagement means for a driver pin on the control rod, e.g. for connecting a corner feed. In this way, a considerable simplification and facilitation of the coupling of two cooperating brackets at the corner of the wing can be achieved in the execution of the assembly.

The invention will now be described in more detail with reference to the drawing.

10 The drawing shows a locking mechanism in connection with a hinged rod system for wing by pivot windows, pivot doors or the like.

As seen in FIG. 1, a control rod 2 is slidably longitudinally below a guide rail 1 and is fixedly connected, e.g. the joint, with a strip 3 which is linearly displaceable in a longitudinal slot 4 in the guide rail 1.

Two sliding wedges 5 and 6 are fixedly arranged one after the other with relatively short spacing 7 on the list 3. The wedge faces 5a and 6a of these two sliding wedges 5 and 6 face in the same direction, but have different inclination, which is particularly evident in FIG. . 3, 6 and 7. The ends of the sliding wedges 5 and 6, which form the wedge tips 5b and 6b, are both located outside the longitudinal faces 3a and 3b of the mold, i.e. that the wedge tip 5b of the slider 5 protrudes beyond the longitudinal surface 3a of the strip 3, while the wedge tip 6b of the slider 6 protrudes beyond the longitudinal surface 3b of the strip 3.

Each sliding wedge 5 and 6 has a locking surface 5c and 6c parallel to the sliding direction of the sliding wedges 5 and 6, which adjoins the associated wedge tip 5b and 6b, respectively, and is displaced parallel to the longitudinal surface 3a and 3b, respectively, of the strip 3.

Furthermore, one outside the longitudinal surfaces 3a and 3b of the strip 3 and parallel offsets with respect to these located locking surfaces 5d and 6d, respectively, adjoins the end of each of the two sliding wedges 5 and 6 wedge surfaces 5a and 6a, respectively. However, these latches 5d and 6d are shorter than the other two latches 5c and 6c.

6 DK 171561 B1 In the shear region 4 limited by the length of the longitudinal slit 4 of the guide rails 5 and 6, a plate 10 is fixed to the underside of the pivotal hinge rod system 9 on the underside of which two fixed counter wedges 11 and 12 are located. at a relatively short distance 13 in succession which is adapted to the distance 7 between the wedge tips 5b and 6b of the shooting wedges 5 and 6.

The counter wedges 11 and 12 are formed by two parallel offsets to the sides in front of each other plate plates 14 10 and 15, each having at one end a wedge surface 11a and 12a, respectively. The two wedge surfaces 11a and 12a border on counter-wedge tips 11b and 12b which face the same path, but from which the wedge surfaces 11a and 11b have opposite inclination direction.

The wedge tip 11b of the counter wedge 11 lies in the same plane as the long side surface 10a of the plate 10, while the wedge tip 12b lies in the same plane as the long side surface 10b of the plate 10.

The inner faces of the two parallel offset pieces 14 and 15 each form a latch 11c and 12c on the counter wedges 11 and 12, respectively, and have a side spacing 16 apart 20 aligned to the width 17 of the two sliding wedges 5 and 6 between their parallel latches 5c. and 5d, 6c and 6d, respectively.

The wedge surface 5a of the sliding wedge 5 approaches the one shown in FIG. 2 shows the right mounting of the hinge rod system in cooperative engagement with the wedge surface 11a of the counter wedge 11 when the wing is to be pulled in closed position against the frame or fixed frame by linear movement of the sliding wedges 5 and 6. In the left-hand mounting of the hinge rod system 8, the wedge surface 6a of the sliding wedge 6 cooperates with the wedge surface 12a of the counter wedge 30 when the wing, by linear displacement of the sliding wedges 5 and 6, has to be retracted to the closing position against the fixed frame or frame.

The length of the wing closing movement is determined by the length of the interlocking wedge surfaces 5a and 11a 35 and 6a and 12a, respectively, on the shooting wedges 5 and 6 and the counter wedges 11 and 12. After these wedge surfaces 5a, 11a and 6a, 12a are pushed past each other, the smallest blocking surfaces 7d and 11c and 6d and 12c respectively on the shooting wedges 5 and 6 and the counter wedges 11 and 12 in working engagement with each other thereby forming a mutual lateral support between the shooting sources 5 and 6 and the counter wedges 11 respectively. 5 team 12.

In order to improve the functioning and stability of the locking mechanism, at a distance 18 behind each counter wedge 11, an auxiliary piece 19 is placed, while at a distance of 20 pounds from each counter wedge 12 there is an auxiliary piece 21. The inner surface 19a of the auxiliary piece 19 lies in the same plane. as the inner surface or barrier 11c of the counter wedge 11, while the inner surface 21a of the auxiliary piece 21 is similarly in the same plane as the inner surface of the counter wedge 12 or barrier 12c.

The auxiliary piece 19 cooperates with the sliding wedge 6, while the auxiliary piece 21 belongs to the sliding wedge 5.

As soon as the latching flanks 6d and 6d of the sliding wedges 5 and 6d respectively engage the ratchets 11c and 12c of the counter-wedges 11 and 12c, respectively, the latching flanges 5c and 6c also come into supporting engagement with the auxiliary surfaces 21a and 19a of the auxiliary pieces 21 and 19 respectively, so that a double is obtained. acts in both directions across the shear direction of the sliding wedges 5 and 6 as well as across the longitudinal direction of the hinge rod system 9 of the hinge bar 8. This provides a 25-free and stable function of the locking mechanism between the window or door wing and the hinge rod system 9.

In FIG. 1-3, it is seen that the locking mechanism is disposed between the guide rail 1 and the hinge rod 8 of the hinge rod system 9 in a location spaced from both the hinge rod 9a hinge 9a of the fixed frame and its hinge point 9a on the wing. When the hinge rod 8 is connected to the wing or guide rail 1 by means of an additional arm 8a, which at each end has only hinges 8b and 8c respectively, the locking mechanism should even lie at a location which is in a region between the hinge of the hinge rod 8 to the frame and Furthermore, the hinge locations 8a, 8c, 8c of the hinge rod 8 and guide rail 1. It may also be advantageous if the locating mechanism of the locking mechanism is closer to the hinge locations 8b and 8c of the auxiliary arm 8a of the hinge rod 8a on the frame.

In FIG. 8-15, a locking mechanism is shown in connection with a hinge rod system for wing or pivot windows, pivot doors or the like.

According to FIG. 8, a control rod 32 is slidably longitudinally below a guide rail 31 and is firmly connected, e.g. the joint, with a slider 33 which is guided linearly displaceable in longitudinal slots 34a and 34b in the guide rail 31. Two counter wedges 35 and 36 are fixed at a relatively short spacing 37 on the slider 33. These two counter wedges 35 and 36 wedge surfaces 35a respectively 36a faces in the same direction but has the opposite slope direction, which is particularly evident in FIG. 11, 13 and 14. The ends of the counter wedges 35 and 36, which form the wedge tips 35b and 36b, are both at the outside of the counter wedges, ie. that the wedge tip 35b of the counter wedge 35 aligns with one longitudinal edge 33a of the slider 33, while the wedge tip 36b of the counter wedge 36 aligns with the longitudinal edge 33b of the slider 20 33.

The inner surfaces of the two counter wedges 35 and 36 extend parallel to the shear direction of the slider 33, each forming a locking surface 35c and 36c, respectively, displaced inwardly relative to the longitudinal edges 33a and 33b of the slider 33.

25 In the longitudinal slide 34a and 34b of the longitudinal slide of the guide rail 31, the pivot system 38 of the plunger 38 is pivoted, a piece 40, on the underside of which is located two consecutive sliding wedges 41 and 42, which have a relatively short spacing 40a, which is 30 aligned with the distance 37 between the wedge tips 35b and 36b of the counter wedges 35 and 36.

Each of the sliding wedges 41 and 42 has at one end a wedge surface 41a and 42a, respectively. Both wedge faces 41a and 42a border on wedge tips 41b and 42b, respectively, which face in the same direction, but have the opposite slope direction from the respective wedge tip.

The wedge tip 41b of the slide wedge 41b lies in the lateral direction 9 outside the longitudinal face surface 40b of the piece 40, while the wedge tip 42b lies outside the longitudinal surface 40c of this piece 40.

Parallel to the shear direction of the counter wedges 35 and 36, these outwardly directed latching flanges 41c and 4ld have 42c and 42d, respectively, the distance of 46 of which is aligned with the spacing 47 between the sliding wedges 41 and 42 of latching surfaces 35c and 36c.

The wedge face 35a of the counter wedge 35 comes at the position shown in FIG. 10, the mounting of the hinge rod system shown in working 10 engages with the wedge surface 41a of the slider 41 when the wing is to be pulled by the operating rod 32 against the fixed frame to the closed position by the linear movement of the slider 33. Upon right mounting of the hinge rod system 38 as shown in FIG. 9, conversely, the wedge surface 36a 15 of the counter wedge 36 interacts with the wedge surface 42a of the slider 42 when the wing is to be pulled against the fixed frame to the closed position by the linear movement of the slider 33.

The length of the closing movement of the wing is determined by the length of the interlocking wedge faces 35a and 41a 20, 36a and 42a, respectively, on the counter wedges 35 and 36 and the sliding wedges 41 and 42. After these wedge surfaces 35a, 41a and 36a, 42a have been shot past each other , at least the latching surfaces 35c and the latching flanges 41d respectively latching surfaces 36c and latching flaps 42d on the counter wedges 35 and 25 36 and the sliding wedges 41 and 42 respectively engage in working engagement, thereby forming a mutual side support between the countercuts 35 and 36 and the sliding wedges 41, respectively.

In addition, to form an additional locking point between the wing and the hinge rod 38 of the hinge rod system 39, on the slider 33 there is also a locking fork 43 having two parallel locking arms 43a and 43b.

The locking branches 43a and 43b each have at their end away from the corresponding counter wedge 35 and 36, respectively, a retracting bevel face 43c and 43d, respectively. The retraction bevel surface 35c has the same inclination position as the wedge face 35a of the counter wedge 35, while the retraction bevel surface 33d has the same inclination position as the counter wedge 36 wedge surface 36a. In addition, the locking branches 43a and 43b have locking flanges 43e and 43f at their inner faces, which are parallel to the locking flanks 35c and 36c of the counter wedges 35 and 36.

For connection to the operating rod 32, the slider 33 has on its underside at and / or near each end a guide and fastener 44 and 45. The guide and fastener 44 protrudes through the longitudinal slit 34a of the guide 31 while the guide and the attachment piece 45 similarly cooperates with the longitudinal slit 10 34b of the guide rail 31. Below the guide rail, the slider 33 over the two guide and fastening pieces 44 and 45 is firmly connected, e.g. assembled, with the control rod 32.

In the distance between the counter wedge 36 and the locking fork 43, approximately at the center thereof, the slider 33 is provided with an opening 48 in the form of a long hole which, at a certain coupling position of the operating rod 32, e.g. at its central coupling position, may be caused to lie against a recess bore 49 formed in the guide rail 31 for a fastening screw. This recess bore 49 is located 20 in the distance between the two longitudinal slots 34a and 34b of the guide rail 31 and is surrounded by a neck 50 extending upwardly over the plane of the guide rail 31 which provides a stiffening of the guide rail profile.

The fastening screw can be passed through the opening 48 of the slider 33 25 and into the recess bore 49 of the guide rail 31 and, by screwing in the material of the wing, is anchored to the wing.

By means of this fixing screw located between the guide rail 31 and longitudinal slots 34a and 34b, the neck of the guide rail 31 is optimized on the wing.

30 In order that the printed neck 50 of the guide rail 33 surrounding the recess bore 49 should not be in the way, the slider 33 is formed at its underside and on each side of the opening 48 with a recess 51, the length of which is adjusted to the maximum displacement distance of the slider respectively. 35 33 and the control rod 32.

The slider 33 is formed in the region of the locking fork 43, respectively, between its locking arms 43a and 43b, with an additional opening 52, e.g. in the form of a round hole which e.g. is located at a coupling engaging means 54 for a driver pin in the control rod 32 and at this location forms a viewing opening through which the connection of the driver pin 5 in a corner passage can be observed when it is to be connected to the end of the guide rail 31 and the control rod 32.

A bolt cam 53, e.g. in the form of a strip or an eccentrically displaceable pin projecting near the sliding wedge 10 42 from the underside of the control arm 38 as clearly shown in FIG. 9, 10 and 12, cooperate with the locking fork 43 and its locking arms 43a and 43b, respectively.

In FIG. 8-10, it is further seen that the latching mechanism is disposed between the guide rail 31 and the hinge rod 38 of the hinge rod system 15 at a location spaced both from the hinge 39a of the hinge rod 38 to the frame and its hinge point 39b to the wing. If the hinge rod 38 is connected to the wing or guide rail 31, respectively, by an auxiliary arm 38a having at both ends only pivot joints 38b and 38c, the locking mechanism is located at a location between the hinge 39a of the hinge rod 38a and the auxiliary arm 38a. hinge locations 38b and 38c to the hinge rod 38 and guide rail 31, respectively.

Due to the constructive association of the locking fork 25 43 and its locking bars 43a and 43b, respectively, with the slider 33 carrying the counter wedges 35 and 36, the locking mechanism can be used in a particularly advantageous manner for such hinge bar systems 39 having a relatively short hinge bar 38 of length. for example. 350 mm or less.
