Definitions

  • the invention relates to a built-in lock, in particular a tubular frame lock for a frame constructed from profiles, preferably an outer door, with a latch and a bolt with a bolt tail that can be fully locked and unlocked by means of two key rotations of a lock cylinder key.
  • a built-in lock in particular a tubular frame lock for a frame constructed from profiles, preferably an outer door, with a latch and a bolt with a bolt tail that can be fully locked and unlocked by means of two key rotations of a lock cylinder key.
  • the invention proposes that the built-in lock is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim.
  • the lock bit works directly, i.e. without Interposition of a gearbox on the bolt, the bolt rotation movement being implemented via the receptacle, preferably at the lower bolt end, in a preliminary movement of the bolt.
  • the locking bit engages in the second driver receptacle assigned to the rear bolt latch end, as a result of which the bolt is pre-locked by the second 10 mm or a comparable amount.
  • the second driver receptacle for the lock bit which, at least essentially, must be the same size as the first driver receptacle, so that in each case the same stroke can be carried out, when the bolt is closed, seen in the bolt feed direction, not have their full size.
  • the second driver receptacle for the lock bit must be brought to its required dimension in the direction of advance in a controlled manner. This process must of course run automatically, both when closing and when closing the bolt.
  • the second driver receptacle is consequently shortened when the bolt is closed, and its extent in the feed direction can be of the order of magnitude of "zero".
  • each of these recordings is open transversely to the direction of movement of the bolt in the installed position of the lock and has the shape of an open slot. Accordingly, each receptacle is bounded at the front and rear by a vertical edge which can be formed on a corresponding projection or the like of the part in question.
  • control lever is pivotally mounted on its upper end in the installed position of the lock by means of a bearing pin of the bolt tail projecting transversely to its plane.
  • the bearing journal could of course also be located on the control lever. It is only important that this bearing journal participates in the outward and inward movement of the bolt during the two partial movements. Accordingly, the control lever is initially when the bolt is closed at the rear end of the lock housing, while it is assigned to the front region of the bolt housing when the bolt is closed. After turning the key, he takes a middle position.
  • a further embodiment of the invention results from claim 3. It ensures that the control lever performs a horizontal movement with respect to its storage when the bolt is closed.
  • the length of the straight slot corresponds to the total stroke of the bolt.
  • a particularly preferred embodiment of the invention contains claim 4.
  • a preferred variant of the invention contains claim 5.
  • the downward projection of the control lever mentioned there forms the rear boundary of the second driver receptacle, while the latter is formed at the front by a projection of the bolt tail or a corresponding undercut.
  • the protrusion and the pivoted projecting extension preferably extend approximately equally far down.
  • the upper limit of the second driver receptacle can be formed by the control lever and / or the bolt tail.
  • FIG. 6 Another embodiment of the invention describes claim 6.
  • This is a built-in lock in which the latch can not only be operated by means of the handle, but also with the help of the key, which is turned in the closing sense when the bolt is withdrawn.
  • This enables the door to be opened from the outside, whereby it should be noted that the handle follower can usually only be turned with the help of a handle located inside the room, while there is a fixed knob on the outside.
  • the above-mentioned rotary movement of the locking bar is converted into a sliding movement of the change, the locking bar usually hitting the lower end of the change and pushing up the change when turning further - viewed from the inside of the door normally clockwise - with a sideways movement superimposed on this stroke movement can.
  • the lifting movement is suitably converted into a transverse movement of the trap in a withdrawing sense.
  • the upper end of the change acts accordingly on a trap tail inside the housing.
  • the parts adjusted in this way are returned via one or more springs which are fitted in a suitable place and in a known manner and which are tensioned via the key when the latch is withdrawn.
  • a particularly preferred embodiment of a lock with change results from claim 7.
  • a further embodiment of the invention results from claim 8. Because of the displaceable mounting of the control plate in the vertical direction, that is to say transversely to the feed direction of the bolt and because of the lateral distance of the guide pin of this vertical guide from the bearing pin, by means of which the control plate is mounted on the control lever, this causes the displacement the control lever through the bolt from the right to the middle position, at the same time also pivoting the control plate around its guide pin. As a result, its rounded front area presses on the inside against the front frame spar of the removable pressure piece and pivots it around its bearing point on the housing in the sense of the locking bar's pre-closing direction. It strikes the inside of the housing or a faceplate that supports the housing.
  • the part actuated during the key-operated retraction of the latch by the lock bit in particular a mandrel-like downwardly projecting end of the alternating pressure piece, is pivoted so far to the side that the lock bit when closing the bolt both during the first and during the passes the second turn of the locking bar. Only at the end of the second turn of the key - when the bolt is closed - are all the deflected parts, including the frame-like part of the alternating pressure piece, returned to the starting position. Now it is possible to retract the latch with the locking bar when the bolt is completely closed.
  • control lever moves from the middle position of the bolt into the fully pre-locked bolt position - with the second turn of the key - in the sense of the pre-closing movement of the bolt. Due to the connection via the bearing pin, it takes the articulated end of the control plate accordingly, but this does not result in any further action of the control plate on the frame or the alternating pressure piece.
  • This is achieved, as the drawing shows, by appropriate shaping of the control plate, which according to the exemplary embodiment has an approximately triangular shape.
  • the alternating pressure piece is not swiveled further and therefore there is no space requirement. Reliable control of the change into the area of the locking bar, or out of this area, is therefore achieved with the smallest space requirement.
  • This built-in lock is preferably developed according to claim 9.
  • the pegs and bolts mentioned there are relatively close to one another, the corners of a small obtuse-angled triangle to mark.
  • the housing or the lock case 1 is fastened to a faceplate 2, for example with the aid of screws 3.
  • a latch 4 in the upper area of the lock and a bolt 5 in the lower area.
  • the lock case 1 is equipped with a receptacle 6 for a locking cylinder 7, in particular a so-called “profile cylinder”, which is provided with a locking bit 8 .
  • the latter can be turned in the sense of the double arrow 9 with the aid of a key inserted into the locking cylinder. If the key is turned starting from the position of the locking bar 8 in FIG. 3 in the direction of the arrow 10, this causes the bolt to be closed by preferably 10 mm (FIG. 4).
  • the fully locked position of the bolt 5 according to FIG. 5 is reached.
  • At least the two positions according to FIGS. 3 and 5, but preferably all three positions, are secured with the aid of a tumbler 11. Starting from its respectively effective blocking positions against the resistance of a return spring 12 in the sense of arrow 13, it can be raised by the necessary amount.
  • the locking bit 8 Starting from its position according to FIG. 3, the locking bit 8 initially runs against the lower end of the tumbler 11 located in its range of motion. In the locking bit positions according to FIGS. 4 and 5, the tumbler is again in its lowered position.
  • the locking mechanism can be accommodated in a separate installation unit.
  • first driver receptacle 16 On the underside of the inner bar end or the so-called Bolt tail 14, seen in the pre-closing direction 15, are a first driver receptacle 16 one behind the other, and behind it a second driver receptacle 17.
  • the first receptacle 16 is formed by two projections 18 and 19 of the bolt tail 14 projecting downwards.
  • the rear projection 19 also forms the front end or the front boundary of the rear or second receptacle 17.
  • the rear end of the latter is formed by a downwardly projecting extension 20 of a control lever 21.
  • the latter is rotatably mounted on a bearing pin 22 of the bolt tail 14.
  • the bearing pin 22 engages in a first straight slot 23 of the lock case 1, which extends in the direction of displacement 15 of the bolt 5, in that it is displaceably mounted in the horizontal direction.
  • the bearing pin 22 according to FIG. 3 is located in the rear right end of the first slot 23.
  • a straight slot part 28 adjoins the oblique slot part 26 and runs parallel to the first slot 23. He is according to the drawing below the first slot 23, the free end of the straight slot part 28 pointing in the closing direction 15, that is to the left in the drawing.
  • the locking bit 8 first engages in the first driver receptacle 16, and via the projection 18, which delimits the first receptacle 16 on the left, it takes the bolt 5 from the starting position according to FIG. 3 into the middle one Position according to FIG. 4.
  • the bearing journal 22 moves from the right end of the first slot 23 into its central region.
  • the control pin 24 presses against the left flank of the oblique slot part 26, so that its displacement by the bolt 5 is superimposed by a counterclockwise rotation, which is possible due to the control groove 25 in the bolt 5.
  • the control pin 24 reaches along the oblique slot part 26 at the transition to the straight slot part 28. The position shown in FIG. 4 is thus reached.
  • the bearing pin 22 and the control pin 24 can move to the left along the remaining part of the first slot 23 or along the straight slot part 28 until the end position shown in FIG. 5 is reached.
  • the catch 4 can, as said, be retracted by turning a handle inserted into the handle follower in the direction of arrow 31, or by actuating a key via a change 29 from the effective position shown in FIG. 1 to an ineffective position which enables the door to be opened.
  • the change consists of two parts, namely the change pressure piece 32 and the change turn piece 33 which extends it to a certain extent.
  • an upwardly projecting extension 34 stands in front of a protrusion 35 of the latch tail 36 projecting transversely upwards, and at the same time it rests on a return spring 37.
  • a rotation of the interchangeable rotary piece 33 in the direction of arrow 31 consequently causes the latch 4 to be withdrawn against the resistance of the return spring 37.
  • This rotation is achieved by an upward movement of the interchangeable pressure piece 32 in the arrow direction 38 (FIG. 1).
  • This in turn is generated with the help of the locking bar 8 turned counter to the arrow 10, this turning movement only being shown in FIG. 3
  • Position of the change 29 is effective because only then is the lower end 39 of the change pressure piece 32 in the range of motion of the clockwise rotating locking bar 8.
  • a sensible mechanism explained below prevents, for example, starting from the position shown in FIG. 5, the locking bit 8 from acting on the change 29 when the bolt 5 is closed.
  • the change is namely after the first turn of the key according to Figure 4 in a tilted to the left. It can be pivoted about a bolt 40 at its upper end. In the exemplary embodiment, this is surrounded by a sliding block, which is displaceable in a vertical slot 42 of the upper end 43 of the alternating pressure piece 32 and can be rotated about the bolt 40.
  • This pin-hole connection enables the change 29 to be pushed up when the case 4 is withdrawn with the aid of the key.
  • the alternating pressure piece is frame-like in the area of the control lever 21 or is equipped with a corresponding window.
  • a control plate 44 rotatably mounted on the control lever 21.
  • the corresponding bearing pin is designated 45.
  • the guide pin 46 at the upper end of the control plate 44 in the drawing, which is in a vertical Guide groove 47 of the tumbler 11 is displaceable to a limited extent. When the bolt 5 is closed and pre-closed, the guide pin 46 is assigned to the upper region of the guide groove 47.
  • the control plate 44 has an approximately triangular shape. Its rounded end 48, which is located at the bottom right in FIG. 3 and which carries the bearing journal, lies against the right vertical edge of the window 49 or the inner edge of the rear frame spar 50 when the bolt 5 is withdrawn. A front rounded region 51 of the control plate 44 lies against the inner edge of the front frame spar 52.
  • the pivoting of the control lever 21 - during the first rotation of the locking bar 8 - also causes the control plate 44 to rotate about the guide pin 46 in the direction of the arrow 53.
  • the front region 51 then presses against the front frame spar 52 of the alternating pressure piece 32 and also pivots it in the sense the arrow 53 around the bolt 40.
  • the lower end 39 of the alternating pressure piece 32 moves out of the range of movement of the locking bar 8, so that when the bolt 5 is closed, the locking bar 8 cannot act on the change 29.
  • the change 29 is only reset at the end of the second closing movement of the bolt 5.
  • the further rotation of the control plate 44 does not cause any further pivoting movement of the change piece 32. Therefore, no additional space is required. You get a reliable one Control of the change with the smallest space requirement, ie even with the smallest backset, a safe-acting change control can still be achieved.
