Definitions

  • the invention relates to a sash retainer, in particular for turn-tilt window sashes, with a bearing base to be attached to one of the two window frames, in particular on the fixed frame, a pivoting arm connected to it, which can be swung out transversely to the sash plane, and a locking arm to be brought into locking engagement on the other frame , in particular to be attached to the casement locking element, the locking arm being provided with a row of teeth and a cover strip that runs equidistantly with the release of a sliding track for the locking element, in which there is a passage point for the locking teeth that are present in the toothed strip with two adjacent locking teeth Locking element is located.
  • Wing locks of the above type are known. They differ from other known sash locks advantageously in that they allow the sash to be locked in different open positions because of the toothed bar provided in its swing-out locking arm and the locking element that can thus be brought into optional locking engagement, thereby allowing the interior of the home to be more or less ventilated.
  • the bearing base the locking arm pivotally connected to it and the locking element made of injection-molded plastic, with only a slightly projecting toothed bar being formed on the comparatively narrow locking arm on both sides of its continuous central wall and the locking element being fork-shaped and with short locking pins arranged on the inside opposite each other between two adjacent locking teeth arranged at the same height on both sides is to be pressed in or out with a pinch.
  • This known wing lock is mostly used in such a way that the swing-out locking arm on the top or bottom of the wing frame and the fork-shaped locking element are attached to the fixed frame, the fork-shaped locking element with its inwardly projecting short locking pin from the articulation end of the locking arm in whose sliding tracks next to the toothed strips are to be inserted.
  • the fork-shaped locking element With its inwardly projecting short locking pin from the articulation end of the locking arm in whose sliding tracks next to the toothed strips are to be inserted.
  • the wing for swivel opening must first be brought into such a partial opening position in which the short locking pins on the fork-shaped locking element come directly in front of the passage points present in the cover strips, so that the locking arm can then be pivoted out of the engagement area of the fork-shaped locking element.
  • the respective pivoting of the locking arm into the fork-shaped locking element after the wing has been completely pivoted is also correspondingly cumbersome in order to be able to determine it in various smaller opening positions.
  • the known generic wing lock is only suitable for absorbing small adjusting forces acting on the locked wing.
  • the previously known wing lock can also be easily pressed open or destroyed or broken off by unauthorized persons, for example boarding thieves, so that even a small window entry security cannot be reached.
  • the invention is based on the object to improve and perfect a wing lock of the type mentioned in such a way that it allows a secure locking of the wing in different opening positions with a comparatively simple and solid design and an extension of the locking element from the locking arm only in the closed position of the window sash or the sash lock.
  • a sash lock is obtained which, due to the much deeper or wider locking engagement between the locking element and the relevant locking teeth, offers greater security against unlocking, but also only allows the locking arm and locking element to be separated when the sash is in the closed position. As a result, such a separation from the outside cannot be carried out in an unauthorized manner.
  • the locking arm In the closed position of the wing, the locking arm is held by the locking element lying at the level of its passage slot while overcoming the spring force in the bearing position on the wing.
  • the locking arm is at the same time increasingly pivoted out by the spring acting on it, and in any case ensures that it is the locking element does not emerge from the passage slot of the locking arm, but rather can slide along its sliding path in order to then be brought into locking engagement with the corresponding locking teeth of the locking arm in the desired tilting end position.
  • the sash is to be pivoted out of the closed position into a rotary opening position
  • the locking arm is simultaneously pressed or held against the fixed frame by manual actuation with the rotary opening, so that the locking element can move freely out of the passage slot of the locking arm.
  • the locking element can slide freely on the top of the locking arm, that is to say on its cover strip, until it arrives in its passage slot and then finally presses the locking arm firmly against the fixed frame again.
  • the spring acting on the locking arm is advantageously designed as a leaf spring located between its articulated arm end and the bearing base, while the locking teeth in the toothed strip overlap the tooth gaps between them, which are adapted in diameter to the locking pin, to such an extent that they move in and out of the locking pin in or oppose a clamping resistance from a tooth gap.
  • the locking arm can be securely clamped in the corresponding tooth gap of the locking arm in the relevant, partially open position of the wing.
  • the locking arm has a bearing surface to be placed flat against the frame, while its toothed strip, the sliding track extending above it for the locking pin and the cover strip provided with the passage slot run in a slightly curved manner. This improves the functionality and also the appearance of the wing stay.
  • the toothed strip is advantageously arranged in the center of the locking arm and on both sides of the cover strip provided with a transverse passage slot exposed, the locking pin is designed as a simple smooth pin, which projects laterally with its free pin end into the sliding track or between two adjacent locking teeth of the locking arm.
  • a wing lock is suitable for optional right or left or top or bottom hinges.
  • the locking arm can be provided with a side wall that connects the toothed strip and the cover strip to one another laterally and covers the guideway on one side.
  • the optional right-hand or left-hand stop option is abandoned, but an even greater stability of the wing lock is achieved, in particular also with regard to its cover strip which equidistantly overlaps the toothed strip.
  • the wing lock ensures sufficient security against being broken open.
  • the locking arm on the bearing base can also be pivoted about a vertical axis, so that the locking arm can also be used to lock the wing in various limited rotary opening positions.
  • a bearing bracket which is rotatable about the vertical axis is articulated on the bearing base and is provided with a bearing eye for receiving the swivel bearing pin carrying the locking arm.
  • the invention provides that a stop collar is provided at the free end of the locking pin, which engages behind the toothed ratchet locking teeth in the locking position of the locking pin to secure it axially. This ensures that the locking arm in its locking positions locking the tilting or rotating opening positions of the sash cannot be pushed sideways over the locking pin, which would otherwise still be possible in principle in the event of an unauthorized attempt to open the window.
  • This additional security can also be contributed by if on the inside of the cover strip facing the toothed strip there is provided a locking strip which extends equidistantly from the toothed strip and which is engaged by the stop collar on the fixing pin in its positions in the sliding path of the fixing arm.
  • the turn-tilt window shown in FIG. 1 has a fixed frame 1 and a sash frame 2 connected to it in such a way that it can be rotated and tilted by means not shown, which is connected on the upper side to the fixed frame 1 by means of conventional opening scissors 10 and can thus be held in a maximum tilted opening position .
  • the actuation of the tilt and turn sash and the connection and locking means accommodated in it takes place via the swivel-adjustable handle 3.
  • the sash lock 4 is arranged, which essentially consists of the bearing base 5 attached to the fixed frame 1, which can thus be swiveled connected, pivotable to the wing plane locking arm 6 and the thus to be brought into selectable locking engagement, attached to the wing frame 2, pin-shaped locking element 7.
  • the bearing base 5 which bears the swing-out locking arm 6 consists of a simple bearing plate 5 which only dash-dotted connection means, such as locking screws, can be attached to the frame 1 lying flat.
  • a swivel bearing eye 5 ' which is encompassed by the fork-shaped projecting bearing eyes 6''at the articulation end 6' of the locking arm and is thus connected in an articulated manner via a swivel bearing pin 8.
  • the locking arm 6 is kept relatively wide and is provided with a centrally arranged toothed rack 9, the locking teeth 9 'of which, as shown in FIG. 4, extend at least over half the width of the locking arm 6.
  • the simple locking pin 7 attached to the sash frame 2 and forming the locking element also projects correspondingly far into the locking arm 6 or its toothed rack 9, so that a correspondingly wide locking engagement results.
  • a sliding track 11 is provided for the locking pin 7, which is covered by the cover strip 12 which extends equidistantly from the toothed strip 9.
  • the cover strip 12 projects with its free end 12 'up to close to the articulation end 6' of the locking arm 6, a free passage slot 13 being provided at both ends for the locking pin 7 between the latter.
  • the locking arm 6 While the locking arm 6 has a flat contact surface 6 '''to be attached to the fixed frame 1, its toothed strip 9, the sliding track 11 located above it for the locking pin 7 and the cover strip 12 provided with the passage slot 13 are slightly curved. At its actuating end 6 IV opposite the pivot bearing end 6 ', the locking arm 6 is also provided on the upper side with transverse adhesive ribs 6 V which increase its grip.
  • the rack 9 is exposed on both sides by the cover strip 12 provided with the passage slot 13, the locking pin 7 with its free pin end 7 'either from the left or from the right protruding into the sliding track 11 or between two adjacent locking teeth 9' of the locking arm 6.
  • a leg-shaped leaf spring 14 is arranged between the locking arm 6, which preferably consists of die-cast metal, and its bearing base 5, which tries to push the locking arm 6 into the pivoted-out position shown in FIG.
  • the locking pin 7 and the position of the cover strip 12 or its passage slot 13 are coordinated so that when the wing tilts and the pivoting of the locking arm 6 of the locking pin 7 by stop at the free end 12 'of the cover strip 12 automatically in the above the rack 9 located sliding track 11 retracts.
  • a brief pressing of the arm 6 or its toothed rack 9 against the locking pin 7 is then only necessary, which then moves into the desired tooth gap 9 '' located between two adjacent locking teeth 9 '' while overcoming a corresponding clamping resistance.
  • the wing 2 is securely locked in the desired tilt opening position shown in FIG. 1 or 3.
  • Unauthorized levering of the locking arm from outside is not possible.
  • the locking arm 6 could be pressed down by overcoming the clamping resistance of the locking pin 7 and the latter thus in the Transfer path 11 of the locking arm 6 are brought.
  • the locking pin 7 could emerge from the passage slot 13, the wing 2 would have to be brought back into its closed position in any case.
  • the locking arm 6 only needs to be pressed against the fixed frame 1 when the sash begins to rotate, so that the locking pin 7 can then extend through the passage slot 13 while the locking arm 6 then, under the influence of the attacking leaf spring 5, returns to its swiveled-out position, as shown in FIG.
  • the wing lock shown in FIGS. 6 and 7 largely corresponds to that described above. Its corresponding parts are marked by the corresponding reference numerals.
  • the locking arm 6 on the bearing base 5 is also rotatably articulated about a vertical axis 15 in order to be able to determine the leaves of windows or doors in various limited rotary opening positions with this wing lock.
  • a bearing bracket 16 which is rotatable about the vertical axis 15 is articulated on the bearing base 5 and is in turn provided with a bearing eye 17 for receiving the swivel bearing pin 8 carrying the locking arm 6.
  • this wing lock differs from the one described at the outset in that a stop collar 7 ′′ is provided at the free end of its locking pin 7, which in the locked positions of the locking pin 7 engages behind the corresponding locking teeth 9 ′ of the toothed rack 9.
  • This stop collar 7 ′′ can also be configured differently than cylindrical, for example be spherical or also conical. This ensures that in the limited wing opening positions, the locking arm 6 cannot be pushed laterally over the locking pin 7, which would otherwise be possible under certain circumstances if an unauthorized attempted break-in or entry was made.
  • the new wing stay is not limited to the application shown for turn-tilt windows or doors. Rather, it can also be used to advantage in simple rotating windows or bottom-hung windows, for example basement skylight windows, for wing locking in limited different opening positions.
  • the locking arm can in principle also be attached to the sash frame and the locking element to be brought into locking engagement on the fixed frame, which would be advantageous, for example, with wings opening outwards.
  • the arrangement of the sash holder shown in FIG. 1 above the window sash actuation handle offers the advantage that it is difficult or impossible for children to reach the arrester, thus preventing an unauthorized, dangerous opening of the window sash.
