Abstract

The turn lock has a main lock casing (4) that includes a central axis (2) and latch (3) which are projected at the inner and outer sides of a faceplate (9) respectively. The insertion openings (13) are provided at the sides of the central axis. A control slider (20) is fixed to the central axis and arranged with recesses (21-24). A tumbler (25) is slidably supported at the control slider and engaged with one of the insertion openings in locking position of the slider.

Description

The invention relates to a turning lock according to the preamble of claim 1 and claim 4.

Generic turning locks are already by the DE 2105132 C known. In the case of the lock known therefrom, a trap arranged along the central axis of the lock is provided which can be pre-closed and retracted by means of a nut, which is likewise arranged on the transverse center axis, with reference to a fold-side forend. The case has on its latch tail engagement recesses for the cam of a cylinder to the recording offset to the transverse central axis and the axis of rotation of the nut two cylinder insertion openings are provided. The case has two-speed locking recesses arranged on both sides of the latch shaft for engagement of the locking bit of a cylinder accommodated in one of the cylinder insertion openings, by means of which a twofold rotation of the locking bit results in a double locking of the latch acting as a latch.

On the latch tail, a tumbler is also effective, which can be pivotally mounted in the housing pivoted by the cam and spring loaded in not in the locking recesses engaging cam comes in a locked position in which a back-pressing the case is not possible.

A disadvantage of the known embodiment is that the cylinder and nut undergo an arrangement in which they are arranged offset in relation to the forehead lying one behind the other in parallel. This leads to an unwanted space requirement of the housing along the central axis and on the other to the fact that commercial rosette fittings with holes for the handle set and cylinder are not usable.

From the CH 49097 an embodiment is known in which the nut and the axis of rotation of a key bit lie on the central axis, which further increases the required installation space.

In another from the CH 264238 known configuration, it is provided that the nut and thus the handle set is placed on the central axis, while the axes of rotation of the key lie in a plane only slightly offset therefrom. The actuation of the key causes due to the one-door restriction only a small exclusion movement of the latch acting as a latch. All in all, the lock needs one large installation space and can also not be used with standard rosette fittings with holes for the handle set and cylinder.

The invention is contrary to the task of finding an embodiment of a Wendeschlosses, which allows a safe closure in a small footprint.

To achieve this object, the invention provides that the two-speed locking recesses are mounted on the engagement of the cam of a recorded in one of the cylinder insertion openings on a control slide, which stores the tumbler. This results in a separation of the trap or the latch tail and the mechanism required for the lock operation on the cylinder or the key.

A further embodiment provides that the tumbler covers the locking recesses of the spool and each tour is associated with a locking recess. This results in two secure positions of the spool.

It is also envisaged that the tumbler is substantially T-shaped and is slidably mounted on the control slide transversely to the central axis and is urged over at least one spring which acts on the tumbler in its blocking position. Although the tumbler is thus floating, it is always subjected to a force of force in the locking position. A stationary storage is not required.

Alternatively, to achieve the desired goal in a turning lock with a main lock box and the same at the height of the central axis of a cuff case, provided on both sides of the longitudinal axis Cylinder insertion, be provided that the Zylindereinstecköffnungen and nuts for a handle operation parallel to the forend Axis lie. In addition to the possibility of a smaller depth, this arrangement also allows the use of standardized fittings.

In this case, it is further advantageous that each nut has a stop arranged at a distance from its axis of rotation parallel to the central axis, against which a nut arm rests in unactuated pusher position, so that the nut remains free of movement components along a plane extending parallel to the central axis through the axis of rotation.

In addition, if in the main lock box relative to the axis of rotation of the nut located diametrically to the stop between the change and the nut a bore for receiving a

Sleeve or threaded bush is provided, this area remains free of moving components.

So it can finally be provided that in the holes and designed as a sleeve stop for attaching a rosette of a fitting usable mounting screws are feasible.

When the control slide is substantially T-shaped and engage at each of its perpendicular to the central axis extending boom arms via a pivot slot coupling to pivot arms which are fixedly mounted in the housing, so that a movement of the spool pulls a pivotal movement of the pivot arms, which pivot arms a To cause longitudinal displacement of the drive rods, this results in a substantially symmetrical structure and mode of action.

Here it can still be provided that in each case a further pivot arm is effective between the pivot arm and the case. The retraction of the case is always so, even with handle operation, on the swing arm.

In order to save installation space and components, it is provided that the pivot arm engaging the latch tail has a common pivot bearing with the pivot arms movable via the control slide.

In order to prevent actuation by means of the pusher in the case of a locked lock, it is provided that a locking lever is effective between the nut and the swivel arm, which locks the nut against pivoting when the latch is closed.

In order to fully fill the function as a turning lock and to have an identical function when turning the lock, it is provided that the drive rods are moved in opposite directions.

That in the Fig. 1 shown lock 1 is designed as a multi-lock reversing lock, hereinafter this is referred to as a lock, wherein a central axis 2 forms a horizontal axis of symmetry. The trap 3 is arranged along the central axis 2 and can be withdrawn along it. In addition to the main lock box 4 at least two with respect to the central axis 2 symmetrically arranged secondary lock boxes 5, 6 are provided, which in turn have bars 7, 8. The secondary lock boxes 5, 6 are connected to the main lock box 4 via a faceplate 9 and two drive rods 10, 11. The lock 1 is therefore a multiple lock. The bars 7, 8 provided in the secondary lock cases 5, 6 can be of different nature, but are symmetrical with respect to the center axis 2 in each case.

In the main lock box 4 two with respect to the central axis 2 symmetrically arranged Cylindereinstecköffnungen 12, 13 are provided. These lie on a common axis parallel to the face plate 9 axis 14. On the axis 14 are also the axes of rotation 15, 16 of two nuts 17, 18, which have polygonal holes for rotationally fixed coupling with a pusher, not shown here a fitting. The fitting, not shown, generally consists at least of a rosette which supports the pivotably mounted pusher and a cylinder rosette which receives the cylinder. When using the lock 1 alternately come the nut 17 together with one of the cylinder insertion opening 13 associated cylinder or - in a pivoted around the central axis by 180 ° insert the nut 18 and the cylinder insertion opening 12 to bear.

It can be seen that the components of the castle court are each mounted symmetrically and / or in pairs, so the description of structure and function of a pair of elements seems sufficient. With reference to the nut 17 and a cylinder mounted in the cylinder insertion opening 13, the structure and function of the lock 1 will be explained below. Nevertheless, reference is made in each case to the corresponding symmetrical design.

The Fig. 2 in conjunction with the Fig. 6 shows the main lock box 4 of the lock 1, which is in unoperated pusher and unlocked, eg in the open position - ie without adjacent to the frame sash or with the sash closed and in a frame-side strike plate engaging case 3. For this purpose, the case 3 protrudes over the faceplate 9. The trap 3 projects with a latch tail 19 into the main lock box 4. Along the central axis 2, a control slide 20 is provided in the direction of displacement of the case 3. The control slide 20 is T-shaped and mounted longitudinally displaceable via a guide pin 36 fixed in the main lock case 4 and a guide (not visible here) arranged in the lock bottom. The latch 3 and the control slide 20 are not directly drive connected. On the control slide 20 closing recesses 21, 22, 23, 24 are mounted on both sides for the engagement of the cam of a received in one of the cylinder insertion openings 12, 13 cylinder. In addition, the control slide 20 forms on the underside a guide for the latch tail 19, in which this engages by means of two parallel to the central axis 2 extending webs an open-edged Langlochausnehmung the latch tail 19. The webs of the control slide 20 form the edge of a Langlochausnehmung, which is penetrated by the stationary guide pin 36, which on the one hand the control slide 20 and on the other hand indirectly the latch tail 19 provides a guide.

The control slide 20 is covered in the representation of a T-shaped tumbler 25 which is mounted transversely to the central axis 2 displaceable on the control slide 20 floating. The tumbler 25 is provided with lateral projections which cover the locking recesses. The bearing of the tumbler 25 is on the one hand via a first trapezoidally curved spring 26 ( Fig. 6 ) and a second U-shaped spring 27 causes, also tumbler 25 and control slide 20 are connected to each other via a guide, as will be explained below. While the first spring 26 on the control slide 20 attackingly engages the tumbler 25 and with two perpendicular to the plane extending end portions 28, 29, the tumbler 25 laterally engages the second spring 27 is attached to a cylindrical projection 30 of the tumbler and engages with their legs 31, 32 in a window 33 of the angled in this area perpendicular to its plane control slide 20 a. Engraved now the cam of the cylinder due to a key operation in one of the locking recesses 23, 24, the tumbler 25 is displaced and attached to the tumbler by knockouts of a window-like section of the tumbler 25 provided locking recesses 34, 35 are together with the tumbler 25th displaced at least approximately parallel to the central axis 2 next to the guide pin 36. If the cam extends out of the closing recess 23, the tumbler 25 displaces due to the application of force by the springs 26, 27 its position along the oblong holes 37, 38 which are penetrated by cylindrical guide pins 39, 40 of the control slide 20. The by the cylindrical guide pins 39, 40 elongated slots 37, 38, form a guide of the tumbler 25 on the control slide 20. Due to the engagement and taking place in relation to the counterclockwise rotation of the cam is the Control slider 20 thereby displaced to the left in the drawing, whereby the tumbler 25 is moved to the left, so that the guide pin 36, the lock recess 34 engages behind. The control slide 20 takes in the Fig. 3 shown location. In the second tour, a further forward movement of the control slide 20 and the guide pin 36 engages behind the locking recess 35 of the tumbler 25. The control slide 20 takes in the Fig. 4 shown location. It follows from all this that the lock 1 is two-speed lockable.

At the in Fig. 3 shown actuating status, the control slide 20 is advanced in a first tour of the cylinder. The control slide 20 has at its transversely to the T-bar 41 extending boom arms 42, 43 respectively in the direction of these extension arms 42, 43 extending slot recesses 44, 45, in which pins 46, 47 of pivot arms 48, 49 engage. The thus formed pin slot coupling 46, 48 and 47, 49 causes at a displacement of the control slide 20, a pivotal movement of the pivot arms 48, 49 which are mounted eccentrically to the pin 46, 47 in the housing formed by the main lock case 4 pivotally fixed. According to the symmetrical arrangement of the pivot arm 49 is thereby pivoted counterclockwise in the drawing and the pivot arm 48 in a clockwise direction. Each pivot arm 48, 49 is in turn connected via a claw 50, 51 with a coupling piece 52, 53 of the drive rods 10, 11.

The pivot bearings 54, 55 on the one hand form the bearing of the pivot arms 48, 49 and on the other hand, the bearing of the pivot arms 56, 57. These are two-armed and a first arm 58, 59 is evidently the Fig. 2 the tail tail 19 associated with a pivot 60, 61. The rotary joint 60, 61 is formed by a circular arc-shaped end of the arm 58, 59, which engages in a correspondingly complementary shaped recess of the latch tail 19. The second arm or arm 62, 63 of the pivot arm 56, 57 has shown the Fig. 5 a perpendicular to its plane angled stop 164, 165 which is associated with a Nussarm 166, 167. This is in a handle operation according to the Fig. 5 pivoted by means of the nut 17 of the pivot arm 56 and the case 3 is withdrawn via the first arm 58.

If the lock 1 is closed by the actuation of the key in its first or second tour, the drive rods 10, 11 are, as already explained above, moved in opposite directions by the pivot arms 48, 49 rotating in opposite directions. The driving rods 10, 11 drive-coupled latch 7, 8 of the secondary lock boxes 5, 6 thereby enter into corresponding bolt receptacles of the stationary frame. A door equipped with the lock 1 is thus closed.

In addition, the lock 1 still allows a change operation. This is evidently the Fig. 2 the control slide 20 and the tumbler 25 covered by a change 64. The change 64 is substantially W-shaped and symmetrical with respect to the central axis 2. A stop 65, 66 is located in the pivoting range of the cam of the cylinder, so that it strikes 20 on actuation and not vorgeschlossenem control slide on this and moved in the drawing upwards. As a result, a horn-like projection 67, 68 comes to rest against a plane perpendicular to the plane of the pivot arm 56, 57 of this projecting driver 69, 70. Due to the eccentric position of the driver 69, 70 relative to the pivot bearing 54, 55 it comes in the presentation to a pivoting movement of the pivot arm 56 in a counterclockwise direction, which leads to a retraction of the case 3.

Another peculiarity arises when the lock 1, as in Fig. 4 shown is preceded by two-speed. At each pivot arm 48, 49 a slot 71, 72 is provided, in which a guide pin of a locking lever 73, 74 engages. A diametrically attached to the guide pin not visible here pins 75, 76 engages in a slot guide the castle ceiling, which also not shown here parallel to the central axis 2 extending guide beads for the locking lever 73, 74 has. As a result, the locking lever 73, 74 in the two-speed pre-closed position of the spool 20 in the direction of the nut 17, 18 is displaced. There, the locking lever 73, 74 engages in a locking recess 77, 78 a. This is the nut 17 in the Fig. 4 prevented from pivoting clockwise with respect to the drawing and the pusher is blocked. In this case, the control slide 20 is shifted so far in the direction of the cuff 9, that this is located immediately behind the case 3 and this secures against pushing back. As a result, the case 3 is effective in this position as a bar.

Another peculiarity of the lock 1 can be seen in the fact that the cylinder insertion openings 12, 13 and also the nuts 17, 18 for a handle operation lie on a common axis 14 or plane parallel to the forend 9. In addition, on this axis 14 or in this plane still holes 79, 80 ( Fig. 1 ), which extend coaxially to holes in the unillustrated castle ceiling and allow the use of a fitting plate.

Each nut 17, 18 has a spaced apart from its axis of rotation 15, 16 parallel to the central axis 2 staggered stop 81, 82. At this is a Nussarm 83, 84 in unconfirmed pusher. Leg springs 85, 86 mounted in the main lock case 4 are assigned to the nuts 17, 18 at a further nut arm and bring about a return of the nuts 17, 18 to the in Fig. 1 shown location. The stopper is designed as a sleeve. In addition, each nut 17, 18 parallel to the axis 14 at the same distance, as the stop 81, 82, a threaded bushing or sleeve in a bore 87, 88 assigned, which together with the rotation axis 15, 16 and the stop 81, 82 on a lies parallel to the central axis 2 extending plane. The boom 62, 63 of the pivot arm 56, 57 provides the necessary space in the main lock box 4. The sleeve or threaded bushing is arranged coaxially to holes 87, 88 of the main lock box 4 and the lock cover.

It is provided that the fastening screws for fixing a rosette of a fitting pass through the holes 87, 88 and possibly existing sleeves or threaded bushes and the stop.
