Description

The invention relates to accessories for a drive rod for windows, doors and the like with locking pins protruding on the drive rods, which in the locked position abut against the fastening arms of the counter locking plates from the frame side, and with a structure for ensuring the position of slot ventilation of the sash relative to the frame in the position of the drive rod control handle.

DE 8316991 U1 discloses a drive rod fitting, which at one closing point has a locking pin supporting, in the locked position of the drive rod fitting, the fastening shoulder of the locking plate. When actuated from the locking position, the locking pin moves along the sash rebate and abuts in the slot ventilation position against the inclined incline directed from the rebate, which pushes the locking pin together with the flap out of the fold. As a result, the locking pin supports the gripping arm, which is limitedly movable and is under the influence of the spring force towards the inside of the fold, which limits the maximum extension of the locking pin. In this case, the sash makes a pivotal movement around the hinge, which is a vertical axis. The maximum deflection is the sum of the distance from the locking pin and gripping arm to the pivot axis.

The disadvantage in this case is that the extension length is fixed and the slot ventilation position is ensured only by supporting one gripping arm with the locking pin. All other locking pins in this arrangement must be moved out of the locking position in order to ensure free movement to the required distance.

This approach is also the basis of the application DE 3041399 A1, where the fastening trunnion as a special fastening element also requires a separate structural component.

DE 102012218887 B4 discloses a striker plate for drive rod fittings, in which a fastening arm for the locked position and a fastening arm for slot ventilation are disposed in the longitudinal direction of the fold with an offset relative to each other. In order for the locking pin and the sash to be pushed out of the fold in the slot ventilation position, the locking slot opening approaches the longitudinal edge of the locking plate located on the room side, as a result of which only a thin-walled lintel remains. In accordance with the fixed distance of the fastening arms, the locking pins of all other striker plates must be pushed out of the fastening arms to avoid pushing when pushing out of the rebate.

A similar design is described in DE 19929818 A1.

From EP 1422372 A1, a concept is known according to DE 3043925 A1.

EP 1 582 673 B1 describes a locking plate with a fixed link guide, in which one locking bar is movable. The location allows the locking bar to adapt to the diverting movement of the trunnion. However, since the rocker rail is stationary, it is not possible to arrange multiple striker plates at different distances from the pivot axis of the sash, as striker plates closer to the pivot axis provide a greater tilt angle than remote striker plates.

EP 1568833 A2 describes lock plates consisting of a base piece and a corresponding movable lock piece. The closure part has a Z-shaped locking slot with two locking arms offset relative to each other, as well as an adjustment channel directed across the fold. The adjustment channel in the direction from the fold is open at the edge and is mated with an adjustment element, which, when entering the adjustment channel, must ensure the specified correspondence of the positions of the locking piece and the locking pin. In addition to the costly design, in the slotted position, the possible reliability is also limited by the presence of only one locking pin.

The applications EP 1568833 A2 and EP 1816292 describe such a drive rod fittings in accordance with claim 1 of the limiting part of the claims.

From EP 1 568 833 A2, a locking plate is known, the rocker-shaped closing slot hole of which is located in the plate body arranged longitudinally to the rebate for movement. The body of the plate is adjusted by means of an adjustment channel located on the sash side on the fittings of the drive rod, which, when the sash is closed, provides a relative correction of the closing slot and the drive rod fittings by means of an adjustment pin. As a result of the insertion of the adjusting pin, a stable position of the plate body is achieved. The disadvantages mentioned in relation to DE 8316991 U1 also occur here, and such manufacturing of all the locking plates is expensive.

The application EP 1816292 A2 is based on the use of a locking plate capable of vertical movement towards the plane of the frame. As a result, the slot opening of the lock, which is also in the locked position under the action of the locking pin, moves, which leads to the fact that the locking plate cannot fulfill its original function of pressing the sash tightly against the frame. For this reason, a drive element is provided which displaces the closure plate appropriately and allows movement of the closing slot.

A common feature of the known designs is that either a single locking pin provides only a limitedly reliable locking, or the entire set of fittings must provide a parallel set-back position, in which specially manufactured hinges are required.

The object of the invention is to eliminate the disadvantages inherent in the prior art.

In the case of the drive rod fittings, the invention provides that the oncoming slope is located on an installation element located under the generatrix of the closing slot, and that in the slot ventilation position (III) the fastening pin is mated with a segment of the locking slot opening that is movable relative to the closing slot. Due to the adjustable approach slope, it is possible to adjust the retraction distance of the corresponding closing slot hole. In this case, the oncoming slope is formed by an installation element located under the forming of the closing slotted opening plate, as a result of which the locking plate consists of a small number of parts, and in the position of slot ventilation, the fastening pin is mated with a segment of the locking slotted opening that is movable relative to the closing slotted hole, which provides movement of the mounting pin and slotted hole segment out of the rebate. This makes it possible to provide a large number of uniform striking plates designed on one window or one door, the retraction distance of which is set depending on the distance to the swing axis of the sash. Since all of these striker plates have identical switching sequences, there will also be a greater number of engaging striker pins in the slot ventilation position, which leads to increased reliability even with the sash forming the slot. The design of the fastening pin in the form of a locking pin also makes it possible to retrofit the existing drive rod fittings, which is possible by replacing the locking plates on the vertical and upper horizontal frame posts with locking plates in accordance with the invention.

In this case, provision is made for the movable segment of the closure slot to be disposed in the carriage overlapping the fastening segment.

For optimal movement of the carriage, provision is made for the locking plate to have an edge projection at the longitudinal ends, longitudinally enclosing the locking plate and the movable carriage, thereby improving the appearance and avoiding acute-angled protrusions.

To ensure high stability, it is provided that the movable segment of the closure slot is located on the pivot arm.

It is also provided here that the lever is connected to the locking plate through a rivet with a collar, which forms the axis of rotation, and a rivet with a full head extending radially to it through the link.

To ensure the possibility of adjustment depending on the place of installation, it is provided that the oncoming slope has a trunnion adjustable in several positions relative to the fixed body of the plate.

The maximum increase in the degree of protection against burglary is achieved if the locking pin is a mushroom-shaped pin, the shaft of which is narrowed towards the center with a minimum play adapted to the width of the closing slot in the carriage.

For a safety advantage, a window or door fitted with a drive bar provides that striking plates of the same design are located on at least three side rails.

If the drive rod hardware includes an extendable structure for the swing-out position, this position is ensured according to the invention in the slotted folding position, since the locking pin in this position is opposite the locking points.

At the window according to FIG. 1, the frame 1 and the sash 2 are connected to each other by means of a scissor support 3 and an angular fastening hinge 4. The scissor support 3 and an angular fastening joint 4 form a lateral vertical pivot axis 5. The scissor support 3 is connected to an exposed structure not shown in the drawing. With the help of the handle 6 and the traction drive connected to it, located in the fold of the sash, various operating modes are set. In the locked position, leaf 2 is locked. In this position, the locking pins on the drive rod fittings are extended so that they take the first end position inside the closing slot and support the fastening arm. In the pivotable open position indicated by II, the sash 2 can make a pivot opening movement, and the locking pins occupy the middle of three possible positions, as a result of which the locking pins reach the area of the closing slot open at the edges and can be removed from the closing slot hole. The sash 2 can be rotated around the vertical pivot axis 5. The third position is the slot ventilation position III. The locking pin is then extended in the direction opposite to the locked position I. In this position, the swing lock is activated on the lower horizontal bar of the frame 7 and at the same time the exposed structure located on the upper horizontal bar 8 of the sash is released and connected to the scissor support 3. If we are talking about a sash equipped with standard drive rod fittings, it can be rotated only about the horizontal axis 9, and the angle of rotation is limited by the exposed structure.

However, in the exemplary embodiment shown, the locking plates are designed in accordance with the one shown in FIG. 2 and 3 with a locking plate 10. It has a Z-shaped closing slot 11, which in the first locked position I moves out of the fold in the direction of the arrow 12, and when moving in the longitudinal direction of the fold 12b is bounded by the fastening arm 13. In the indicated in FIG. 2 pivot open position II, the locking pin mated with the locking plate 10 is located in the area of the side hole 14. The locking pin, which was previously moved into the closing slotted hole 11, can pass through the hole 14 when the flap 2 rotates along the pivot axis 5. If in the first segment 15 of the locking slot the hole 11 is located parallel to the rebate, the segment 16 is made oblique to it. Adjacent to it is the second segment 17 parallel to the rebate.

The locking slot 11, divided in this way into three segments 15, 16 and 17, is formed on the one hand by the contour of the cover plate 18 and, on the other hand, by a guide bar 19 located under the cover plate 18. The guide bar is an integral part of the lower part 20. shown in FIG. 4 as a separate part. The interaction of the locking pin and the guide bar is described in EP 1208281 B1, which is fully referenced here. In accordance with the locking fittings disclosed there, the locking pin, which is designed as a mushroom pin, is supported by the head 29, which is enlarged opposite to the rod, which is tapered towards the center, on the guide bar 19, which first ensures the distance of the rod from the cover plate.

As seen in FIG. 4, an obliquely extending segment 16 adjoins segment 15. Segment 16 forms a ramp 35 for the locking pin and is an integral part of the locating element 22. The locating element 22 is diamond-shaped and forms a segment 17 of the locking slot running parallel to the segment 15. The positioning element 22 fits into the receiving recess 23 of the lower part 20. The receiving recess 23 is inclined with respect to the longitudinal direction 12b of the fold in such a way that the side 25 always runs parallel to the guide bar 19. The position of the positioning member 22 is adjusted inside the receiving recess 23 and relative to the guide bar 19. This can change the value 24, which corresponds to the parallel displacement of the guide bar 19 and the side 25.

The fixing of the positioning element 22 takes place in the cover plate 18, as shown in FIG. 2 and 3. The locating element 22 extends by a pivot 26 disposed therein by a pivot 26, a recess 27 consisting of several intersecting drilled holes. Overlapping drilled holes lead to constrictions 28 of the recess 27. On the trunnion 26 is a head 29 having parallel cuts 30. The remaining cylindrical jacket 31 and the cut 30 are sized to the recess 27 so that the cylindrical jacket 31 has a larger diameter than a gap between two opposing constrictions 28. At the same time, the distance between the slices 30 is smaller than the gap between two opposing constrictions 28, which provides, at a certain turn in accordance with the enlarged cutout in FIG. 3 movement and fixation of the journal 26 inside the recess 27.

In order to provide the locking pin in the area of the locking slot segment 17 with reliable engagement of the locking valve, the locking slot 11 in this area is located in the carriage 32, movable relative to the lower part 20 and the cover plate 18. The carriage 32 can, through two longitudinal holes 33 and passing through them, the guide pins 34 move vertically to the rebate direction 12b. In the slot ventilation position III, the locking pin acting as a fastening pin is located in a locking slot movable with respect to the closing slot opening 11 and, accordingly, segment 15, segment 17 of the locking slot opening.

The location provides the following operating principle. Based on the locked position I, the locking pin, when actuating the drive rod fittings, moves along the guide bar 19. Upon reaching the hole 14, the sash 2 can be pivotally opened and makes a pivotal movement around the vertical axis 5. The drive rod fittings are in the pivot opening position II. Another movement from the pivot opening position II in the direction of the slot ventilation position III leads to the fact that the locking pin collides with an inwardly displaced incoming slope 35 of the setting element 22. With further movement in the same direction, the locking pin is pushed out of the plane of segment 15 and In this case, it encounters a protruding fastening arm 36 of the carriage 32, which as a result moves in the direction of the arrow 12. The flap 2 thereby rotates by one angle, starting from a plane-parallel position. This, as already mentioned above, can be a pivotal movement around the lower horizontal axis 9. For this, on the lower horizontal crossbeam 7 of the frame, a folding lock is required, which will secure the sash 2 to the frame 1 with the possibility of rotation. The exposed structure located on the crossbar 8 of the sash is in this situation, in a principally known manner, in the swing-open position, in which the upper edge 37 of the sash can be detached from the frame 1. A locking plate 10 located in the rebate zone 38, with which the locking pin of the exposed structure or corner switch is coupled in the corner zone 39 in the direction of the rebate zone 40, it will push the upper edge 37 of the sash away from the frame 1 in the slot ventilation position.

In an alternative design, provision can be made for the pivot movement to take place around the pivot axis 5. Here, the scissor support 3 and the angled fastening joint 4 are designed as pivot joints. Exposed construction is not required. The locking plate 10 located in the rebate zone 40 pushes the flap edge 41 away from the frame 1, and the flap 2 pivots about the pivot axis 5.

Common to both designs is that the other locking pins of the drive rod fittings interact with the locking plates 10. For this purpose, the locking plates 10 must be positioned appropriately. The locking plates 10, placed on the crossbeam of the frame located opposite the axis (pivot axis 5 or 9), have here a maximum value 24 of the setting element 22. For the locking plates 10 placed on frame posts adjacent to the corresponding pivot axis 5 or 9, a smaller magnitude 24.

In this way, all existing locking pins can be mated to the locking plates 10. In practice, it has been found that when reinstalling a window equipped with an extendable structure, it is possible to leave the locks on the lower frame 42 for the tilting position. This arrangement provides the above-described re-installed sash with a secure ventilation position in which the burglar will encounter formidable obstacles.

In order to increase the strength of the striker plate 10, as shown in FIG. 2-4, that the movable segment 17 of the locking slot located in the carriage 32 overlaps the fastening segment 43. The fastening segment 43 is flatter than the rest of the lower part 20 and has through-drilled holes 44 for fastening screws. The fastening screws prevent the locking plate from turning in the event of a burglary attempt in order to release the locking pin from the support-based connection with the fastening arms 13, 36 by acting on the leaf with a large lever force. FIG. 4, it can be seen that the locking plate 10 has at its longitudinal ends a cover plate 18 that encloses in the longitudinal direction and a movable carriage 32, an edge protrusion 45, which not only contributes to an improvement in appearance, but also provides a better movement of the carriage 32.

FIG. 5 shows another example of implementation. In this case, the lower part 20 is substantially identical to that shown in FIG. 4, and the cover plate 18 as well as the positioning member 22 perform the same function. However, the segment 17 of the locking slot is here provided in the lever 46, which is pivotally arranged on the cover plate 18 and the lower part 20. The pivot position is ensured by the fact that the lever 46 through the pivot-forming rivet 47 with a head and extending radially to through the link 48 a rivet with the head 49 is connected to the cover plate 18. In the example of embodiment, the link 48 is located in the lever 46. However, it can also be provided that the lever 46, located on it in the form of an integral part of the T-shaped guide protrusion, engages with the corresponding link on the cover plate 18. The shape of the lever 46 and the position of the rivet 47 with the head do not adversely affect the rotatable fastening of the lever 46. The operating principle is as previously described. When moving from the pivot opening position II in the direction of the slot ventilation position III, the locking pin collides with an inwardly displaced incoming slope 35 of the setting element 22. Upon further movement in the same direction, the locking pin is pushed out of the plane of segment 15 and collides with a protruding the attachment arm 36 of the lever 46, which as a result pivots according to FIG. 5 counterclockwise. In this case, the locking pin is tightly closed and moves from the plane of the segment 15 towards the interior of the room.

Shown in FIG. 6 the lower part 20 of the exemplary embodiment according to FIG. 5 shows the movable arrangement of the mounting element 22 in the accommodating recess 23. At the same time, it can be seen that the fastening segment 43 is here also made flatter and has, in addition to the through-drilled holes 44, a bore hole 50 for a rivet 49 with a head that functions as a rivet guide. and a drilled hole 51 for a pivotal rivet 47 with a head. In addition, a groove 52 is provided on the fastening segment 43, including a drilled hole 51. A coiled spring, not shown, is immersed in a shallow groove 52, which rests on one side of the lower part 20 and on the other side engages a lever 46, which is thereby pushed into the shown in FIG. ... 5 starting position. As a result, an automatic return of the lever in the pivot opening position II and the closing position I is ensured. Due to this, the pivot lever adapts, if necessary, to the locking pin sliding along the incoming slope 35 and does not protrude into the rebate, interfering with the pivot opening position II.
