    Coupling system for a lock
    The invention relates to a coupling system for a lock.
    Lock cases with a lock nut are known from the prior art, which are actuated by a mechanical handle, which is usually connected via a square pin with the lock nut. The actuation of the handle, such as a door handle, causes a rotational movement of the lock nut and triggers the return of a locking element, such as the case of the castle from.
    In particular, for electromechanical locks, it is known not to connect the lock nut directly to the locking element, but to provide a switchable coupling system, which can be activated by an electromechanical system, such as a relay. In the open state, the coupling system is disengaged, so that actuation of the handle causes no actuation of the locking element. In the closed state, the coupling system is engaged, so that actuation of the handle causes actuation of the locking element. Such electromechanical coupling systems are particularly suitable for use in buildings, inter alia, since only low energy is needed to activate the relay. Thus, a power supply can be done by batteries, which also allows the retrofitting of existing systems in buildings.
    Such coupling systems usually comprise a rotatable outer coupling part and an inner coupling part, which is mounted in the outer coupling part substantially concentric and rotatable relative to the outer coupling part.
    Furthermore, a, usually electromechanically actuated, coupling element is provided, which is designed to let the two coupling parts against each other rotatable in a resting state and in a working state, the two coupling parts rotatably connected to each other.
    A problem of such known coupling systems is that the rotational position of the two substantially concentric coupling parts to each other in the rest position can not be met in each lock case. Some lock boxes require a certain rotational position of the coupling parts to each other for mounting the handle, so that it can not be determined with certainty before assembly, which rotational position the two coupling parts will occupy each other in the rest position. As a result, however, the secure engagement of the coupling element in both coupling parts for rotationally fixed connection is made difficult or impossible. As a remedy, additional parts are used in practice, which allow a rotation of the rest position of the coupling parts by a certain angle of rotation, for example 2 ° or 4 °, in a certain direction. However, the use of these additional parts is cumbersome and error-prone, and should therefore be avoided in practice.
    The object of the invention is to provide a coupling system which allows a robust non-rotatable connection of the coupling parts without additional parts, even if in the rest position, the two coupling parts are in a variable and not provided rotational position to each other.
    These and other objects are achieved by a coupling system according to claim 1. In this coupling system, a coupling element is provided, which is designed to non-rotatably connect the outer coupling part in a variable rotational position with the inner coupling part. The coupling element can therefore also, when the outer and the inner coupling part are in an unavailable rotational position to each other, the two coupling parts rotatably connect.
    According to the invention it can be provided that the outer and inner coupling part are made substantially circular or substantially annular. In particular, the outer and inner coupling part can be designed as a coupling rings. However, it can also be provided according to the invention that the outer and inner coupling part have an elliptical or rectangular shape.
    According to the invention it can be provided that the coupling element is mounted linearly displaceable in a recess of the inner coupling part along a first axis, wherein for displacement, a, in a circumferential recess of the outer coupling part along a second axis linearly displaceably mounted actuating element is provided. This actuating element can in particular be designed such that it can actuate the coupling element, ie can move linearly. The actuating element may in particular be a pin which is mounted in a peripheral opening of the outer coupling part and can be displaced along its longitudinal direction by an electromechanical actuator, for example a relay or a lever connected to a relay.
    According to the invention it can be provided that the coupling element an operating area for actuation by the actuating element and a connection area for non-positive or positive connection with a provided on the inner circumference of the outer coupling part engagement surface are provided.
    The actuating region and the connecting region of the coupling element can be connected via a web. In particular, it can be provided that the coupling element is made in one piece. In particular, it can further be provided that the connecting region and the actuating region are arranged at opposite ends of the coupling element.
    According to the invention, it can be provided that the actuating region has a circular section-shaped cross-section which covers a larger angular range of the inner circumference of the outer coupling part than the recess for receiving the actuating element.
    It is thereby achieved that the actuating element, the coupling element even then move laterally, so can operate when the displacement axis of the coupling element and the displacement axis of the actuating element are not aligned collinear with each other. Although the actuator then presses obliquely on the coupling element, but as long as the angle deviation is not too large and the force of the actuator is strong enough, this still causes a longitudinal displacement of the coupling element.
    According to the invention, it can be provided that the connection region and the engagement surface have a circular section-shaped cross-section, wherein the engagement surface covers a larger angle range of the inner circumference of the outer coupling part than the connection region. This has the effect that the connection region can be brought into connection with the engagement surface even if the displacement axis of the coupling element and the displacement axis of the activation element are not arranged collinearly but at an angle to one another.
    According to the invention, it can be provided that the connection region and the engagement surface are designed with latching elements, in particular with a corresponding toothing. Of course, a purely frictional connection between the connection area and the engagement surface can also be provided.
    According to the invention, it may be provided that the circular section defined by the engagement surface on the inner circumference of the outer coupling part has a center angle of 30 ° to 90 °, preferably about 60 °. According to the invention, it can further be provided that the circle section defined by the connection region has a midpoint angle of 15 ° to 45 °, preferably approximately 30 °, on the outer circumference of the inner coupling part.
    The center angle is the angle defined by the ends of the respective circumferential circle section with respect to the center of the axis of rotation of the coupling parts.
    According to the invention, it can be provided that the circular section defined by the recess for receiving the actuating element has a center angle of 2 ° to 10 °, preferably approximately 5 °, on the inner circumference of the outer coupling part. According to the invention, it can further be provided that the circle section defined by the actuating region has a center angle of 10 ° to 40 °, preferably approximately 24 °, on the outer circumference of the inner coupling part.
    According to the invention it can be provided that a return element, in particular a compression spring, is provided for returning the coupling element to its rest position.
    For this purpose, the coupling element may have a recess for receiving the return spring, and the inner coupling part has a stop for the compression spring.
    According to the invention it can be provided that a further return element, in particular a torsion spring, is provided for returning the outer coupling part or the inner coupling part to its rest position. For this purpose, the outer coupling part or the inner coupling part may have a projection for engagement of the torsion spring.
    According to the invention, it can be provided that the outer coupling part can be connected or connected to a handle for actuating the lock and / or with a locking element for locking and unlocking the lock, in particular with a latch of the lock. According to the invention can also be provided that the inner coupling part with a handle for actuating the lock and / or with a locking element for locking and unlocking the lock, in particular with a case of the lock, connectable or connected. This causes that in the engaged state, that is, when the inner and outer coupling part are rotatably connected, rotation of the inner or outer coupling part by actuation of the respective handle has the operation of the case of the lock result.
    The invention further comprises an electromechanical lock with a coupling system according to the invention. This may in particular be an electromechanical lock for use in a building.
    Further features of the invention will become apparent from the claims, the description of the embodiment and the drawings.
    In the following, the invention will be explained in more detail using the example of a non-exclusive embodiment.
    Fig. 1 shows an embodiment of a coupling system 1 according to the invention in an idle state. In this embodiment, the inner coupling part is designed as an inner coupling ring 3, and the outer coupling part as an outer coupling ring 2; However, the invention also extends to embodiments in which inner and outer coupling part have a different shape, for example, circular, elliptical or rectangular.
    The coupling system 1 comprises the outer coupling ring 2, the inner coupling ring 3 and a coupling element 4. The outer coupling ring 2 and the inner coupling ring 3 are arranged substantially concentrically and rotatably mounted about the same axis of rotation in a (not shown) housing.
    In the inner coupling ring 3 is a, normally oriented on the axis of rotation, recess 10 is provided. In this recess 10, a coupling element 4 is arranged, which is displaceable along its longitudinal axis 5, as indicated by the double arrow. However, the coupling element 4 is positively introduced with respect to rotational movements in the recess 10, so that a rotation of the coupling element 4 relative to the inner coupling ring 3 is not possible. A (not shown) return element 13 ensures that the coupling element 4 is moved after a displacement along its longitudinal axis 5 back into the rest position shown.
    The outer coupling ring 2 has connecting means (not shown) to be connected to a first handle for actuating the lock. Also, the inner coupling ring 3 has (not shown) connecting means for connection to a second handle for actuating the lock.
    The coupling element 4 is elongate and comprises an actuating region 6 and a connecting region 7 arranged opposite to one another, which are connected to one another via a web. In the present embodiment, the coupling element 4 is in one piece, but there are also embodiments of the invention, in which the coupling element 4 is multi-piece.
    The actuating portion 6 of the coupling element 4 has a circular section-shaped cross section, which is designed flush with the outer surface of the inner coupling ring 3. For receiving the actuating region 6, the inner coupling ring 3 has a corresponding recess 10.
    On both sides of the actuation region 6, projections on the coupling element 4 ensure that the coupling element 4 can not be pressed out of the inner coupling ring 3. These projections cooperate with corresponding stops on the inner circumference of the inner coupling ring 3 positively to achieve this effect.
    The actuation region 6 of the coupling element 4 projects through a recess in the circumference of the inner coupling ring 3 and terminates flush with the outer circumference of the inner coupling ring 3. In the region of this recess is located on the circumference of the outer coupling ring 2 an opening in which a displaceable actuating element 8, in the present embodiment in the form of a displaceable pin, is mounted.
    The actuating element 8 is arranged in the illustrated first rest position of the coupling system 1 relative to the coupling element 4, that both the actuating element 8, and the coupling element 4 along substantially the same longitudinal axis 5 are displaced, as indicated by the two double arrows.
    This causes the actuating element 8, the coupling element 4 along the longitudinal axis 5 against the restoring force of the (not shown) return element 13 can move.
    At the opposite end of the coupling element 4 is a connection region 7, which is guided in a further circumferential recess of the inner coupling ring 3. The connecting portion 7 is designed for positive engagement in an engagement surface 9 on the inner circumference of the outer coupling ring 2. For this purpose, both the connecting region 7 and the engagement surface 9 have a corresponding toothing. In the illustrated first rest position of the coupling system 1, however, the connection region 7 is not in engagement with the engagement surface 9.
    Fig. 2 shows the coupling system 1 in a second state of rest, wherein the inner coupling ring 3 is arranged rotated to the outer coupling ring 2.
    In this second resting state, the longitudinal axis 5 of the actuating element 8 is not collinear with the longitudinal axis of the coupling element 4, but these axes are arranged at an angle to each other.
    However, even in this second resting state, a displacement of the actuating element 8 along the axis 5 causes a longitudinal displacement of the coupling element 4, so that in this twisted position, a positive coupling of the outer coupling ring 2 can be effected with the inner coupling ring 3.
    For this purpose, the actuating portion 6 of the coupling element 4 has a circular section-shaped cross-section which covers a larger angular range of the inner circumference of the outer coupling ring 2, as the actuating element 8. Accordingly, the recess 10 for receiving the actuating portion 6 in the inner coupling ring 3 is greater than the recess for receiving the actuating element 8 in the outer coupling ring. 2
    On the opposite side, both the connecting portion 7 of the coupling element 4, and the engagement surface 9 of the outer coupling ring 2 is designed with a circular section-shaped cross section, but the engagement surface 9 covers a larger angular range of the inner circumference of the outer coupling ring 2, as the connecting portion. 7 It is thereby achieved that the connecting region 7 can also come into positive connection with the engagement surface 9 when the longitudinal axis 5 of the actuating element 8 is not collinear with the longitudinal axis of the coupling element 4, and the longitudinal displacement of the actuating element 8 thus standing at an angle Displacement of the coupling element 4 causes, as indicated by the two double arrows.
    In the present exemplary embodiment, it is provided that the circular section defined by the engagement surface 9 has a center angle of approximately 60 ° on the inner circumference of the outer coupling ring 2. It is likewise provided that the circular section defined by the actuating region 6 on the outer circumference of the inner coupling ring 3 has a midpoint angle of approximately 24 °. Of course, embodiments with other values of the midpoint angles are also provided according to the invention.
    Fig. 3 shows the coupling system 1 in the first operating state, starting from the first rest position shown in FIG. 1. The actuator 8 is linearly displaced and pushes the coupling element 4 against the force of the (not shown) return element 13 along the longitudinal axis 5 on the opposite side , As a result, the connecting region 7 engages in the engagement surface 9, and the coupling element 4 is positively connected to the outer coupling ring 2. Since the coupling element 4 is rotatably mounted in the inner coupling ring 3, this coupling causes a torque on the outer coupling ring 2 is transmitted directly to the inner coupling ring 3.
    As soon as the actuating element 8 is moved back, the coupling element 4 is moved back into its rest position by the restoring element 13, so that the coupling of the outer coupling ring 2 with the inner coupling ring 3 is canceled again.
    FIG. 4 shows the coupling system in the second operating state, starting from the second rest position according to FIG. 2. The actuating element 8 is displaced inward along a longitudinal axis and presses against the circular-segment-shaped outer surface of the actuating region 6, so that the coupling element 4 is displaced along its longitudinal axis. At the opposite end of the connecting portion 7 of the coupling element 4 engages in the engagement surface 9 on the outer coupling ring 2 a form-fitting. This ensures that the outer coupling ring 2 is rotatably connected to the inner coupling ring 3 in this rotational position.
    Shown is the outer coupling ring 2, the inner coupling ring 3, the actuating element 8, the coupling element 4, and the return element 13. It is both the recess in the inner coupling ring 3 for receiving the actuating portion 6, as well as the connection area 7 of the coupling element 4 visible.
    In the present embodiment, both the inner coupling ring 3 and the outer coupling ring 2 is designed with a connecting region for receiving a first and second handle for actuating the lock.
    Fig. 5b shows a view of the coupling system 1 in the assembled state.
    Fig. 6a shows a further exploded view of the coupling system 1, but from a different angle. In this illustration, the engagement surface 9 provided with a toothing is visible on the inner circumference of the outer coupling ring 2. Furthermore, a projection 12 is provided on the end face of the outer coupling ring 2. This projection 12 engages in a (not shown) return spring 14, which serves to restore the outer coupling ring 2 in its rest position after actuation.
    Fig. 6b again shows a view of the coupling system 1 in the assembled state from a different angle.
    Fig. 7 shows an exploded view of an embodiment of a lock nut, which includes a coupling system 1 according to the invention. For clarity, not all components of the locknut were called. Shown is that the coupling system 1 is connected to a manual handle in the form of a square, which engages in the outer coupling ring 2. A return spring 14 in the form of a torsion spring engages in the (hidden in this view) projection 12 on the outer coupling ring 2 a. The coupling system 1 is inserted into a housing of the lock nut and there is provided an electrical relay, which can move the actuating element 8 along its longitudinal direction via a lever mechanism.
    The invention is not limited to the present embodiment, but includes all coupling systems within the scope of the following claims.
