On the sleeve 12 of the rotary button 10 inside, a three-piece adapter unit is arranged, composed of a cylinder adapter 34, an element 30 of closure and a support cap 36.

The cylinder adapter 34, made of metal, it has in a plane parallel to the leaf 80 of the door, a form of the cross section corresponding to that of a cylinder conventional closure, for example, configured as a cylinder profiled, round or oval. The cylinder adapter 34 is inserted in corresponding openings of the door leaf 80 and of the lock 90, and thus, arranged in solidarity in rotation in the lock 90.

The closure element 30 also composed of metal, comprises a bushing-shaped support sector 31, in the that a pallet 33 is formed for the actuation of a latch not shown on the lock. Pallet 33 ends at beams with the axial end of the support sector 31 in the form of cap, turned in the arrangement according to the figure, towards the button 10 interior swivel. Consequently the closing element 30 It has an asymmetric structure.

On the support bushing 36, made of plastic, the adapter 34 of the cylinder and the closing element 30, being able to rotate relative to each other in such so that the closing element 30 meets its sector 31 of support between two sectors 35 support, annularly, of the adapter 34 of the cylinder. In the adapter 34 of the cylinder a recess 38 for pallet 33, which allows a 360º turn of the closure element 30 relative to the adapter 34 of the cylinder. Consequently the cylinder adapter 34 is also asymmetric structured.

The rotation axis position of the unit closure according to the invention - around which the rotary buttons 10, 50, bushing 12, shaft 52 and element 30 of closure - is then fixed by the adapter 34 of the cylinder and through the corresponding openings in sheet 80 of the door and in the lock 90.

The socket 12 of the inner rotary knob, it has a guide groove 19 extending in the axial direction, which is configured as notch in the wall of the bushing, which part from the free end of the bushing 12. The guide groove 19 it acts in combination with a guide and drive rib 32 of the closure element 30, and which is formed on the side opposite the pallet 33, on the inner wall of the support sector 31 in the form of bushing, and extending in axial direction throughout its length.

In the support bushing 36 a slit 37 which is configured as a notch that starts from the left axial end in the figure of the support bushing 36. In consequently also the support bushing 36, presents a asymmetric structure The guide and actuation rib 32 of the closing element 30, penetrates through the slit 37 of the bushing 36 of support both inside the guide groove 19 oriented with the slit 37, of the socket 12 of the inner rotary knob, that the guide and drive nerve 32 ends almost beams with the wall inside of cap 12 of the inner rotary knob.

Inside the housing 11 of the rotary knob 10 inside a cylindrical coupling unit 40 is arranged in which is configured a guide channel 42. The free terminal zone of axis 52 of the outer rotary knob 50, with which the axis 52 in the guide channel 42, is flattened, and thus has a non-circular cross section corresponding to the free cross section of the guide channel 42, so that the axis 52 -and, therefore, the outer rotary knob 50- is attached solidarity in rotation with the coupling unit 40.

By a stop 56 that is configured in the end of the flattened area, turned towards the rotary knob 50 outside, the maximum plug depth of the axis 52 on guide channel 42.

A connection element 24, configured as plug, is axially movable within channel 42 guide, and plugged into a bushing element 59, which is attached solidarity in rotation and axially immovable, with the axis 52 of the button 50 swivel outside. The cross section of element 24 of connection corresponds to the non-circular cross section, of axis 52 and, therefore, to the free cross-section of channel 42 guide, in which the element 24 of Connection.

The guide channel 42 of the unit 40 of coupling, transforms in front of its farthest front face of the door leaf 80, in a hole 25 of smaller diameter, which drive out through a drill 13a configured in the cover 13.

By means of an electric link conduit 22, extending through hollow shaft 52, which comprises individual signal and supply lines, element 59 of bushing is connected with a unit for introduction of a code, arranged on the outer rotary knob 50, and covered in the figure by its cover 53. The unit for introducing a code, is configured as receiving unit of a unit of responder, and connected by connecting element 24 to a control unit and actuator unit drive, which It is integrated in the coupling unit 40. In this way the coupling unit 40 is an integral part of the unit responder

The external rotary knob 50 is provided space for a battery unit or a rechargeable unit of accumulator, for the supply of power to the system closing.

The command and drive unit comprises together with electronic building components, an engine with which a pin-shaped drag heel can be operated, not represented in the figure, which extends parallel and displaced with respect to the axis of rotation of the closing unit. For the supply of current to the motor, the link conduit 22 serves.

Using the engine, the heel of the reciprocating drag, between a drag and a gear position free, finding the drag heel in its position of drag, fitted, and in its freewheel position, without engaging with recesses 14.

Each of the recesses 14 is provided in shape of a drill in a single-drive drag disc 16 piece with socket 12 of the inner swivel button 10. A multitude of such recesses 14, is arranged near the edge of the drive disc 16, distributed in peripheral direction. The disc 16 drag forms a front side area of the housing 11, and a support surface for the coupling unit 40, arranged in her.

Consequently, the motor can be carried the coupling unit 40 optionally to a drag state or of freewheel, the coupling unit 40 being when the drag heel will penetrate one of the recesses 14, in the drag state, which allows rotation of the rotary button 10 inside and, therefore, of pallet 33, by button 50 external swivel.

In the coupling unit 40 a sensor not represented by movement, which is configured to indicate a turning movement of the coupling unit, and serves for by preparing a corresponding signal, block an axial movement of the drag heel between its state of drag and freewheel, while turning the unit coupling

The operation of the closing system according to the invention is as follows:

The socket 12 of the inner rotating button 10, is inserted with the adapter unit plugged into the openings provided for this from the leaf 80 of the door and the lock 90, until the spring 17 for fixing the shield 15, snaps into the recess 18 for fixing the bushing 12.

Here, on the one hand the asymmetric structure of the adapter unit composed of the cylinder adapter 34, closure element 30 and support bushing 36, allows insert that one before inserting it in lock 90, optionally with either pin 33, or with the axial end opposite of the closure element 30 in front, on the bushing 12 of the inner rotary knob 10.

In this way the closing system according to the invention can be used in doors where the lock 90 is arranged near one of the side surfaces of the sheet 80 of the door, and of course regardless of whether it is your inner or outer face.

In the arrangement according to the figure, sheet 80 of the door is thinner on the side of the lock 90 turned towards the inner rotary knob 10, which on the opposite side, of so that the closing element 30 is arranged on the bushing 12 so that it is returned with its pallet 33 towards the inner side of the door

The adapter unit is then taken to the desired axial position on bushing 12, in which the blade 33 can operate the lock latch 90.

To do this, the adapter unit can move simply reciprocating over bushing 12, sliding the bushing 36 along the outer wall of the bushing 12, and the guide and actuation rib 32 of the element 30 being guided closing, through the guide groove 19 of the bushing 12.

Then, axis 52 of button 50 is introduced external swivel through socket 12, and with its free end in the guide channel 42 of the coupling unit 40, until the shield fixing spring 57 is engaged in recess 58 for fixing the shaft 52.

To prepare the plug-in electrical link between the bushing element 59 installed at the free end of the axis 52, and the connection element 24 arranged in the channel 42 of guide, connection element 24 can be applied from the outside with a counterbuterola that can be introduced by the hole 13a of the cover 13 and through the hole 25 of the coupling unit 40.

The correct relative orientation of element 59 of bushing and connecting element 24, is guaranteed by the non-circular cross-section of axis 52, of channel 42 of guide and connecting element 24, which only allows plugging shaft 52 in bushing 12, for relative angular orientation correct.

The stop 56 of the axis 52 prevents that, for thicknesses too small of the door leaf, shaft 52 will penetrate too much in the coupling unit 40, and that the element 24 of connection, press, for example, against a plate or other electronic building components that are arranged in the area of the side of the coupling unit 40, further from the leaf 80 of the door.

The axial displacement capacity of the unit adapter on bushing 12, the possibility of turning the asymmetric structured adapter unit, as well as the introduction of one into the other, of telescopic type of bushing 12 and of axis 52, allow an adaptation of the closing system according to the invention, both at different thicknesses of the door leaf, as also, to different axial positions of the lock 90 inside sheet 80 of the door.

This adaptation is carried out in the manner described Previously, simply when assembling the locking system during installation on the door leaf, not having to constructively modify in any way for this adaptation, none of the building components of the closure system.

Turning the inner rotary knob 10 will drag the closure element 30 through the guide groove 19 configured in its socket 12, and by means of the guide rib 32 and actuation of the closing element 30, and thus rotates together with the support bushing 36 also dragged by the guide and drive rib 32, relative to the adapter 34 of the cylinder. By means of the pallet 33, the lock latch 90, and the door open or get stuck in at all times by means of the inner rotary knob 10

The unit for entering a code configured as the receiver unit of the responder unit, in the external rotary knob 50, reacts to an authorization code, for example, in the form of a radio or induction signal, which transmits to the receiving unit through a transmitter that basically It can be configured anyway.

The issuer can take it with a person authorized to access, for example, in the form of a card credit.

Upon receiving the authorization code, the unit receiver sends the motor of the coupling unit 40 through the link conduction 22, to change from the idle state to drag state, that is, to either allow, or prevent, an actuation of the lock latch 90 by means of the button 50 swivel outside.

The motion sensor of unit 40 of coupling, configured to indicate a rotation movement, is take care to prohibit a step of the heel of drag from its position of drag to the freewheel, or vice versa, as long as you turn the unit 40 coupling.

This is advantageous, for example, when the system Closing is provided with an automatic timer which, after if a programmable interval of time elapses in the connection to the step of the coupling unit 40 to the drag position, it take care that the drag heel automatically returns to its freewheeling position. This automatic decoupling of outer swivel button 50 and inner swivel button 10, can be prevented by the motion sensor when towards the end of the time interval, an authorized person presses button 50 external swivel.

In the above-described embodiment of the closure system according to the invention, through the hollow shaft 52 of the outer rotary knob 50, an electrical signal path is accordingly extended, in the form of the link conduit 22. Alternatively, an optical signal path may also be provided, for example, in the form of optical fibers.
cas.

Instead of the described unit of responder, in the closure system according to the invention can be basically used any unit for entering a code, which is in conditions of transforming an encoded signal into signals electrical or optical, together with a coupling unit that can be sent by these signals, and thus can Switch between a drag and a freewheel state. The unit for entering a code, could be configured, by example, for the differentiation of fingerprints or other individualizing body notes, and then authorize only a switching of the coupling unit when the finger print - or another characteristic body note - of a person authorized for access.
