Description

NEN 9.7, which attack in recesses 10 of the sliding bolt 8 (so that when the sliding bolt is moved 8 the spinning roller is rotated. The rotating roller 9 is non-rotatably connected to a shooting rod 11, which is on both sides protrudes from the lock case and gripper hooks not shown at their ends in a known manner carries, which engage in the closed position in the end piston.

The actuating part 6 has a continuous square hole 12 and a diagonal slot 13. The square hole 12 is used to accommodate the square mandrels of security cylinders, rotary handles and cylinder olives. The slot 13 is designed in such a way that it ^{can accommodate all shapes of key bits of tumbler keys, in two positions rotated by 180 'J with} respect to one another.

A round recess 6a with cylindrical side walls is attached to the rear of the actuating part 6. A cylindrical part Tb of the bolt drive part 7 is rotatably guided in this recess. The locking drive part 7 has a round eccentric disk 7a to which a driving pin Tc is attached. The pin Tc engages in a semicircular groove Sb which is arranged in the rear of the actuating part 6. Stop surfaces 6f on the actuating part 6, which interact with stops (not shown) in the lock case, limit the expandability of the nut part 6 to 360 ".

The operation of the lock described is as follows: If z. B. the actuating part 6 rotated by 360 ° by means of a tumbler key, the first half-turn by 180 ° is empty, ie the bolt drive part 7 is not rotated. Only during the second half-turn is the driver pin Tc engaging in the groove 6b taken along, so that the bolt drive part 7 is rotated through 180 °. The eccentric disc Ta engaging in a recess in the sliding bolt 8 then moves this plate into its closed position, the closing rod 11 being pivoted at the same time. When the lock is opened, the process is reversed, ie the Ricgel drive part 7 is only rotated during the second half-turn.

Of course, the driver pin Tc could also be arranged on the actuating part 6 and the semicircular groove bb 11111 bolt drive part 7.

Claims (1)

Claim: Espagnolette lock with a lock case, a rotatable lock rod, a sliding bolt which is in engagement with the rotatable lock rod via a toothing, and with a two-part nut rotatably mounted between the lock case base and cover, which consists of an actuating part guided through a hole-shaped opening in the lock case cover there is a slot embedded in it on one side for receiving the beard of a tumbler key and a bolt drive part arranged behind it, which has an approximately round eccentric disk which, approximately in the axis of symmetry of the sliding bolt, cooperates drivingly with driver stops of the sliding bolt, the actuating part and the bolt pin secondary part by means of a lateral driver pin driver stops formed by a partially circular recess is coupled with emptying in such a way that when the actuating part is rotated by 360 °, the bolt drive part is only rotated a maximum of 180 °, characterized in that the actuating part (6) in addition to the slot (13) has a continuous square hole (12) for a rotary handle actuation or lock cylinder actuation, that the part-circular recess is formed by a part-circular groove (6b) and that the bolt drive part (7) by means of a cylindrical area (7b) formed on both sides is rotatably mounted on the one hand in a bore (4) of the lock case base (1) and on the other hand in a round recess (6a) of the actuating part (6). The invention relates to an espagnolette lock with a lock case, a rotatable shooting rod, a sliding bolt which is in engagement with the rotatable locking rod via a toothing, and with a between the lock case base and cover rotatably mounted, two-part nut, which consists of a Hole-shaped breakthrough of the lock-box cover guided, actuating part with embedded therein on one side Slot for receiving the beard of a tumble key and a bolt drive part arranged behind it consists, which has an approximately round eccentric disk which is approximately in the axis of symmetry of the sliding bolt drivingly cooperates with driver stops of the sliding bolt, wherein the actuating part and the bolt drive part by means of a lateral driving pin and a part-circular Recess formed driver stops is coupled with idle travel that at a Rotation of the actuating part by 360 °, the bolt drive part is only rotated a maximum of 180 °. Such an espagnolette lock, which has become known from German OS 20 63 003, eliminates the disadvantage conventional espagnolette locks that tumbler keys can only be withdrawn from the lock can when the locking plate is in the shooting rod. While this is beneficial in many cases, however also disadvantageous under certain circumstances. For other reasons, too, it is often desirable if that is necessary for the displacement of the Ricgelpiattc Rotation movement of the key is a full 360 °, while yes for the displacement of the locking plate in their In the closed position and back, the key only needs to turn 180 °. In the espagnolette lock according to DE-OS 20 63 003, however, there is the disadvantage that to a optional actuation of the lock by means of different actuators a sometimes considerable Reconstruction of the lock is required, so that it is not easily possible to use such an espagnolette lock optionally to be converted according to the purpose for the different types of actuation. Also exists the difficulty that the two-part nut with the actuating part is only correctly guided and stored on one side, so that if the sliding bolt or There is a risk that the rod will bend these parts and then the lock will not bend at all can be opened or closed more. The invention is therefore based on the object of providing an espagnolette lock of the presupposed type (DE-OS 20 63 003) so that with improved storage of the nut parts optionally an actuation by means of Bit key, lock cylinder or rotary handle is possible without complex conversion. To solve this problem, the invention provides that the actuating part in addition to the slot has a continuous square hole for a twist grip actuation or lock cylinder actuation that the part-circular recess is formed by a part-circular groove and that the bolt drive part by means of a cylindrical area formed on both sides on the one hand in a bore in the lock case base and on the other hand is rotatably mounted in a round recess of the actuating part. This special design according to the invention results in an arrangement in which the two-part nut is guided and supported on both sides in such a way that tilting and catching is effectively excluded. The other features, some of which are known from DE-OS 23 38 947, make it possible to convert a normal espagnolette lock, which is already known in this laid-open specification, to optional actuation by means of keyed keys, lock cylinders or rotary handles.
The invention will be explained in more detail below using an exemplary embodiment and with reference to the drawing. It shows 1 shows a cross section through the lock case of an espagnolette lock,
F i g. 2a, 2b, 2c front view, cross-section and rear view of one part of the nut, and F i g. 3a, 3b, 3c front view, cross-section and rear view of the other part of the nut. The lock according to FIG. 1 has a lock case with a lock case bottom 1, which by a Lock cover 2 is closed. On the lock cover 2 a sleeve 3 is attached, which is not in a hole engages the door shown and which is intended to accommodate various inserts, which the Actuating means are adapted, which are used to open and close the lock. In bores 4, 5 of the lock case bottom 1 or of the cover 2 is a composite of two parts 6 and 7, respectively Nut rotatably mounted. The actuating part 6 of the nut is shown in Figs. 2a, 2b and 2c, while the bolt drive part 7 of the nut in the same manner in FIGS. 3a, 3b and 3c is shown. In the lock case there is also a sliding one Sliding bolt 8 and a rotating roller 9 with two Ziih-
