Abstract

In order to house, and facilitate changing, the battery (9) the lock (2) is enlarged by the addition of a cover (1) extending a distance (8) in front of the lock outer (52) into which the key (6) is inserted to energize the circuit (3) to activate the bolt (5).

Description

The present invention relates to a combination of rosette and an associated lock cylinder according to the preamble of the main claim.

Essential to the present new combination of a rosette with associated lock cylinder is an integrated into the lock cylinder electrical load, which is then moved via an electrical circuit from a lock into a release position when a key is authorized access is inserted into the lock cylinder. In this case, an electrically energizable blocking element is activated by the electrical circuit and the rotational movement of the cylinder core is released. The electrical circuit can be housed in the rosette, in the lock cylinder or split in the rosette and in the lock cylinder.

In a specific prior art embodiment, such a lock cylinder in addition to the electrical load and mechanical tumblers, via corresponding mechanical cuts or recesses in the key can be brought from their lock into their release position, if a key authorized to access is used.

Such special lock cylinder is known, for example from the US 600 609 A or the EP 743 412 A ,

This lock cylinder the EP 743 412 is characterized by a compact design. In addition to the mechanical tumblers, both the electrical circuit and the activatable by electric current blocking element and the electrical energy storage are housed in the cylinder housing.

It must therefore not be fallen below in this lock cylinder a minimum length, otherwise not all of these modules can be accommodated within the cylinder housing.

Due to the aforementioned dimensions of such lock cylinder, the inclusion of larger batteries or other components such as charging circuits in the cylinder housing designed difficult, as long as the relevant length of the lock cylinder is not increased. Although the length on the outside or inside can be increased easily. Larger outdoor lengths, however, always mean the use of correspondingly thick door panels in the door panel thicknesses of the usual folding doors in Germany, to prevent the gripping of the over the door leaf protruding end of the lock cylinder with a pair of pliers or the like. Larger interior lengths require optical reasons for correspondingly thick inner shields.

It is therefore an object of the present invention to develop a rosette for combination with an associated lock cylinder of the known type so that the cylinder housing for the installation of electronic modules available standing space for installation in standardized folding doors is increased.

This object is achieved by the invention with the features of the main claim.

The invention provides, inter alia, the advantage that now the electrical energy storage without removal of the lock cylinder is accessible. For this purpose, only the rosette must be removed, so that the electrical energy storage located within the rosette is easily replaceable.

In addition, since there is more space in the rosette, larger capacity batteries can be installed, so that the time intervals for replacing the batteries are larger.

These advantages are achieved in that the electric energy storage instead of the lock cylinder is now housed in the associated rosette, wherein devices for transmitting electrical energy can be provided between the rosette and the projecting part of the lock cylinder, the energy storage in the rosette with the electrical circuit and connect the electrical loads in the lock cylinder.

The energy transfer can be made contactless or contactless. For this purpose, embodiments are given.

The main idea of the invention is the outsourcing of the electrical energy storage from the cylinder housing in an adapted to the lock cylinder escutcheon, in addition, the energy exchange between rosette and lock cylinder is also to ensure.

The escutcheon essential to the invention is not involved in the mechanical protection against mechanical violence of the door leaf and is thus in a simple manner - also theft-proof - mounted on the inside of the door panel.

The attachment of the rosette, however, must be done directly on the lock cylinder regardless of whether on the inside already sits an inner rosette or an inner shield.

For this purpose, embodiments are given.

A major advantage of the rosette is the virtually unlimited size, which can be within the usual fitting dimensions or more readily.

For this reason, can be accommodated within the rosette next to the electrical energy storage and other modules for special functions. Again, embodiments are given.

Nevertheless, and in particular for interior doors, the rosette according to the invention can be mounted on the lock cylinder both on the outside of the door and on the inside of the door. However, since the rosette can also accommodate assemblies with special functions such as key recognition or registration of key times or the like, it must be decided case by case where the rosette is located.

On the other hand, the arrangement of the rosette on the inside of the door of exterior doors offers the additional advantage that no additional anti-theft devices, etc. are provided.

Advantageous embodiments will be apparent from the dependent claims.

Unless otherwise stated below, the following description applies to all figures.

The figures show a rosette 1 with associated lock cylinder 2. The lock cylinder 2 includes an activatable by electric current blocking element 5, which is arranged in the cylinder housing.

This may be an electromagnetically or electromotively driven pin, which in its locking position exceeds the separation gap between the rotatable lock core 39 and the cylinder housing and thereby retracts into a corresponding bore of the lock core 39.

Such blocking element 5 is spent by an access-authorized key 6 via the electrical circuit 3 from its blocking in its release position, so that then - access authorized key - the lock core 39 can be rotated.

The electrical circuit 3 is housed in the embodiment in the lock cylinder 2. He serves to control the locking element 5. The circuit 3 can also sit in the rosette 1 or split on escutcheon 1 and lock cylinder 3.

It is essential that in the rosette 1, an electrical energy storage 9 is housed, which is the power supply the locking element 5 within the lock cylinder 2 is used. For this purpose, devices for transmitting electrical energy 10, 11, 14, 15, 16, 17 are provided between the escutcheon 1 and the lock cylinder 2, of which the devices associated with the escutcheon 10, 14, 16 are connected via electrical lines 12 to the energy store 9 and the locking cylinder 2 associated devices 11,15,17 are connected via electrical lines 13 to the circuit 3, which serves to spend the blocking element 5 from the blocking in the release position.

It is essential to be able to apply electrical current to the electrical blocking element 5 via the devices 11, 13, 15, 17 associated with the lock cylinder. This can be done for example via a permanently installed cable connection between rosette 1 and lock cylinder 2.

The figures show consistently locking cylinder 2, which are designed as a profile cylinder and have a circular cylindrical area for receiving the lock core 39, as well as an immediately adjoining web-like area 38th

Expediently, the devices for transmitting electrical energy 10, 11, 14, 15, 16, 17 are each present in pairs and are attached on the one hand to the inner circumference of the rosette and, on the other hand, to the protruding part of the lock cylinder. In the embodiments shown are located on a corresponding flattening on the underside of the cylinder web ram or sliding contacts 15 which are brought together with corresponding upward facing tracks 14 on the rosette 1.

Apart from this contact-bound transmission of the electrical current can also communicate contactlessly with each other Antennas 16,17 are used, such as FIG.5E shows. In addition, the use of data bus lines is possible.

The use of antennas also offers the advantage that in addition to the transmission of electrical energy between rosette 1 and lock cylinder 2 and electrical information between access-authorized key, 6 and lock cylinder 2 can be transmitted. For this purpose, the rosette 1 associated antenna 16 must be integrated into a corresponding electrical circuit 26 for data reception and / or data evaluation of the data stored on the access-authorized key data.

The data exchange between authorized access key 6 and lock cylinder 2 but via a separate pair of antennas 50,51, wherein the lock cylinder 2 associated antenna 51 is seated in the front end functional module 46 a, which is located on the outside 49 of the door panel 7. This functional module has an electrical connection to the electrical circuit 26, which may be housed in the lock cylinder 2 or in the rosette 1.

Expressly, this electrical circuit 26 for data reception can also be accommodated within the lock cylinder, provided that the transmission of the electrical energy from the rosette 1 to the lock cylinder 2 and for the transmission of the access authorization data from the key 6 to the circuit 26.

The use of data bus lines allows for a high variety of transmission possibilities with a small number of lines

In addition to this shows 4a an embodiment in which the data exchange between key 6 and rosette 1 by means of a rosette 1 associated antenna 16 via a non-contact pairing of transponder 50 and associated transponder reading device 51 takes place. Here, the transponder reading device 51 is integrated in the electrical circuit 26 for data reception and is located within the rosette. 1

As 4a combined with 4c shows, on the not acted upon with a rosette according to the invention outer side 49 of the lock cylinder 2, a corresponding transponder reading device 51 is provided, which in turn communicates directly with the arranged within the key tag transponder 50 and the electrical circuit 3, within the lock cylinder 2 or within the rosette. 1 or split within the lock cylinder 2 and can sit inside the rosette 1, acted upon by corresponding signals.

Here, however, should also be arranged in any case, the electrical energy storage in a arranged on the inside 48 Rosette 1 according to the invention, so that even the sitting inside the lock cylinder electrical circuit 3 for the blocking element 5 receives its energy from there, while the access-authorized key 6 on the outside 49 of the door panel 7 is inserted.

In addition to this shows Fig.5f an embodiment in which the data exchange between rosette 1 and lock cylinder 2 via a pair of photodiode 18 and photoreceiver 19 takes place, in which case the component of photodiode 18 and photoreceiver 19, which is associated with the rosette 1, in the electrical circuit 26 for data reception can be involved.

In addition to this shows FIG.5E an embodiment in which the electrical circuit 26 includes a transmitter 17.1, either in the rosette 1 or in the Lock cylinder is housed. The transmitter 17.1 is used to identify or recognize the access-authorized key 6 data to be transmitted, which in turn can only get over a corresponding data connection to the transmitter 17.1.

In addition, it can be provided to pre-assign the evaluation electronics 17.1 in the lock cylinder a control electronics 20 housed in the escutcheon 1, which serves to act on the electrical circuit 3 in the lock cylinder with a blocking or enable signal. This training shows 4a where the control electronics 20 communicates via a corresponding data line with an associated receiver within the lock cylinder 2.

In addition to this shows 4b a development in which the rosette 1 is provided with a receiving unit 21, which serves the exchange of information with another external information source 22,24. This is an information source to understand that is not coupled with the key crop, but for example as a programming device 24 or the like. Is formed. Data lines 23 may be provided as data lines, which are connected, for example, to a data processing installation permanently installed on the building side.

In particular 4b 1, the receiving unit 21 may communicate with the external information source 22 in a contactless or contact-bound manner.

Furthermore, it may be useful to provide an electronic memory 25 in the evaluation circuit 26, which serves for the permanent storage of the transmitted data, which may be overwritten, for example, when reprogramming to another access-authorized key.

It should be noted that the electronic memory 25, the control electronics 20, the rosette-side antenna 16 and possibly the transponder 50 and the transponder reading device 51 can all be integrated into the rosette-side circuit 26 for data reception.

To complicate unauthorized manipulation, the electrical energy storage 9 should be accessible only after disassembly of the rosette 1 from the door leaf 7.

This can be made possible for example by means of a concealed screw fastening. Alternatively, the figures show the use of a clamping screw 43, which is solvable only with a non-standard special tool.

In addition, in particular, shows Figure 7 in that the rosette 1 is connected to the lock cylinder 2 via a trigger lock 27. For this purpose, for example, an inwardly spring-loaded locking pin is provided, which sits in a radial bore of the cylinder housing and is supported with his foot on the rotatable cylinder core. In this case, the locking pin projects beyond the cylinder housing and engages with the protruding part in a pocket 28 of the rosette 1. The rotatable cylinder core has on its circumference a flattening, which passes at a predetermined rotational position under the foot of the locking pin so that it moves out of the counter pocket and sinks into the cylinder housing. In this position, the rosette can be removed.

In addition to this shows, for example 3a a development in which the attachment of the rosette 1 on the lock cylinder 2 within a predetermined longitudinal area is everywhere possible. For this purpose, a predetermined axial clearance 41 is provided, within which the rosette 1 on the lock cylinder 2 can be reciprocated in the axial direction.

In addition to this shows Figure 6b the arrangement of an acoustic or optical signal transmitter 29 on the rosette 1 as well as a - preferably invisible - clock module 43, which can also be supplied via the electrical energy storage 9 with electrical energy.

Additionally shows 6a the optional arrangement of a display 30 and the arrangement of a solar cell 32 on the outside of the rosette. The solar cell 32 is integrated in a charging circuit 31, which serves for the continuous charging of an electric energy accumulator 9 designed as an accumulator.

Alternatively, the electrical energy storage can also consist of one or more batteries 9 or be formed by a capacitor circuit.

In order to prevent the rosette 1 is unauthorized manner can be additionally provided a cover contact 34, which is incorporated in an alarm circuit, which is closed at unauthorized removal of the rosette 1. A particular advantage of the rosette 1 according to the invention in conjunction with a profile cylinder is that the rosette can complete the web-like region of the profile cylinder over a cylinder web cover 44 completely.

In this development, the associated profile cylinder 2 is the front side so far covered that only the circular cylindrical portion of the profile cylinder remains accessible together with the lock core 39 for receiving the key 6.

As already mentioned, the arrangement of the rosette on the outside 49 or the inside 48 of the door leaf 7 is optional.

Alternatively, corresponding rosettes could be arranged on both sides of the lock cylinder 2, in particular if the rosette 1 contains functional modules with special functions, for example clock modules 33, for example for storing the key use times, which can preferably be electrically readable.

In addition to this shows 4a the use of a rosette 1 as an additional rosette, which is placed on a lock cylinder 2 belonging and in relation to the rosette 1 smaller fitting rosette 35. To prevent here that the attached rosette, which is equipped with battery, is forcibly engaged behind, a relining piece 36 is provided which is rigidly connected to either the door leaf 7 or with the attached escutcheon 1 and also can not be removed by force.

This purpose is a screw 47, which holds the relining piece 36 in its intended position.

In addition to this shows 5c a lock cylinder 1, which also contains mechanical tumblers 42 in addition to the basically existing electrically activatable blocking element 5, which can be brought from their blocking into their release position via corresponding cuts or recesses in the access-authorized key.

Known manner, these are pairings of core and cylindrical pins, which are aligned over the respective depth of the incisions or recesses so that they with access authorized key with their common contact surfaces lie in the parting line between lock core 39 and cylinder housing. In this regard, reference is made to the prior art.

In addition, it is shown here that the mechanical tumblers 42 are arranged solely in the circular-cylindrical region 37 of the profile cylinder, while the electrically activatable blocking element 5 is accommodated within the cylinder web 38 of the profile cylinder.

It should be pointed out that with the rosette 1 according to this invention, in particular lock cylinder 2 can be combined, in which the electrical / electronic / electromechanical components of the electrical circuit 3 can sit in separate function modules 46a and 46i, the front side in the cylinder web 38 are attached. In particular 4c shows, the function modules of the different end faces, depending on whether they sit on the outside 49 or the inside 48, differ from each other. Decisive on the outside (49a) functional module 46 is the antenna 51, which communicates with the associated antenna 50 in the key. The inside (48) function module 46i preferably serves to receive the plunger or sliding contacts 15. When the illustrations from FIGS 4a, b, c and 5a to f, the attachment of the cylinder-side electrical lines is readily possible even with the help of ram or sliding contacts on a corresponding function module 46i and simplifies the construction costs for the lock cylinder. 2
