The present invention relates to a rosette for one assigned lock cylinder according to the preamble of the main claim.

Essential to the present new combination of a Rosette with associated locking cylinder is one in the Locking cylinder integrated electrical consumer, the via an electrical circuit then from a blocking in a release position is placed if an authorized user Key is inserted in the lock cylinder. In in this case, one that can be activated by electric current Locking element activated by the electrical circuit and released the rotary motion of the cylinder core. The electric one Circuit can be in the rosette, in the locking cylinder or divided in the rosette and housed in the locking cylinder his.

In a special previously known embodiment such a lock cylinder in addition to the electrical Consumers also use mechanical tumblers that have corresponding mechanical incisions or recesses in the key can be brought from their blocking position into their release position, if an authorized key is used.

Such a special locking cylinder is for example known from the EU 96 107 056.

This locking cylinder is characterized by a compact Construction. In addition to the mechanical tumblers are both the electrical circuit as well as that by electrical Electrically activated blocking element and the electrical energy storage housed in the cylinder housing.

Therefore, a minimum overall length is allowed for this locking cylinder not fall below, otherwise no more all of these assemblies housed within the cylinder housing can be.

Due to the dimensions of such locking cylinders is the inclusion of larger batteries or other assemblies such as charging circuits in the cylinder housing difficult, as long as the relevant length of the locking cylinder is not enlarged. Although the overall length enlarge easily on the outside or inside. Larger external lengths mean that the door leaf thickness the folding doors usual in Germany always use of appropriately thick door plates to grip the end of the locking cylinder protruding from the door leaf with pliers or the like to prevent. Larger inner lengths for optical reasons request accordingly thick inner shields.

It is therefore an object of the present invention to Rosette for combination with an assigned locking cylinder the known type so that the cylinder housing available for the installation of electronic assemblies standing space for installation in standardized folding doors is enlarged.

Since there is also more space in the rosette, larger capacity batteries can also be installed, so the time intervals for replacing the batteries grow.

These advantages are achieved in that the electrical Energy storage instead of in the lock cylinder the associated rosette is housed, with between the rosette and the protruding part of the locking cylinder Devices for the transmission of electrical energy are provided can be the energy storage in the rosette with the electrical circuit and the electrical consumers in connect the lock cylinder.

The energy transfer can be contact-based or contactless respectively. Exemplary embodiments are given for this.

The main idea of the invention is the outsourcing of electrical energy storage from the cylinder housing in a rosette adapted to the locking cylinder, whereby additionally still the energy exchange between the rosette and the locking cylinder is to be ensured.

The rosette is not essential to the invention mechanical security against mechanical violence of the Door leaf is involved and is therefore simple - too theft-proof - mountable on the inside of the door panel.

The rosette must be attached immediately on the lock cylinder regardless of whether on the inside already an inner rosette or an inner plate sitting.

Exemplary embodiments are given for this.

A key advantage of the rosette is that it is practical unlimited size, which is easily within the usual fitting dimensions or above.

For this reason, can be placed inside the rosette next to the electrical energy storage also other assemblies accommodate for special functions. Exemplary embodiments are also used for this specified.

Nevertheless, and in particular with interior doors, the invention Rosette on the lock cylinder on both the Door outside as well as be attached to the inside of the door. However, since the rosette also assemblies with special functions such as key recognition or Registration of key usage times or the like must be decided on a case by case basis the rosette is arranged.

On the other hand, the arrangement of the rosette on the Door inside of external doors the additional advantage that no additional anti-theft devices etc. have to be provided.

Advantageous embodiments result from the subclaims.
