Abstract

A closing system for doors having a container provided in a handle. The container has a touch surface that is placed in a window-type recess of the handle, and a switching element that is arranged in the container can be actuated by the touch surface. The switching element is used to switch the control electronics of the closing system between two states, namely a state that prevents opening of the door and a state that allows the door to be opened.

Description

The invention is directed to a locking system in the preamble of claim 1 In such a locking system is by means of a in a Handle integrated switching element activates control electronics, via the one on a vehicle door, flap or body arranged lock of one, one Opening a door, flap od. Like. Preventive state, in one, an opening a door, flap od. Like. Enabling state is transferred. The Field of application of the invention is directed in particular to motor vehicles, Access to security zones etc.

In locking systems of the above type, it is known to give access to a person e.g. a vehicle via a data query of a data carrier, for example a Credit card to enable (keyless go). The data query is here by a on the door, flap od. Like. In the region of the handle attached mechanical Switching element triggered, which on a door handle or at least in the area a door handle is installed. The person requesting access triggers the data query of the data carrier by a control unit, e.g. in a vehicle, through a Actuating the switching element, more precisely, by moving the handle out. The triggered pulse is thereby transmitted from the control unit to a transmitter passed the data query to the disk. Of the Disk receives the data query command and passes it to a Data unit that forwards the requested data to a sender. The transmitter then transmits the data again via the vehicle-side transmitting / receiving unit to the control unit in the vehicle, which in case of a positive data recognition a Issues command to unlock the locking system.

The switch related electronics are replaced by potting, e.g. protected with a plastic compound against water access. This is in the production time consuming and expensive.

Furthermore, the data query is done only on a first actuation of a handle, as a handle bar or a handle flap of a door handle, and when the User pulls on this and thus triggers the switch. The data query so happens at a relatively late date, as, as from the above Description is to be followed, a few steps later. This delayed Data query, as well as the subsequent reaction time of a central locking make such a system uncomfortable. In some cases this has the consequence that the locking system is not unlocked at the first actuation of the door handle and the person desiring access must re-operate the door handle to to open a door.

Furthermore, from DE 197 45 149 a handle for a motor vehicle door known, which consists of two shells. Inside the inner shell is located a switching element, which is constructed as a transmitter / receiver unit. This Switching element is covered by an insulating layer. Located in the outer shell a recess for a push-button, the locking of the locking system by pressing enabled. A disadvantage of this device is that the Casting the switching element in the inner shell, e.g. with plastic mass one represents time-consuming production.

The object of the invention is to provide a locking system in the preamble of the claim 1 type to develop, which avoids the disadvantages mentioned. this will According to the invention by those mentioned in the characterizing part of claim 1 Measures which are of particular importance.

The peculiarity of the measures described therein lies in the switching element to integrate into a container, the at least one accessible page one Has button for actuating the switching element. The handle has a On receiving, in which the container with the switching element during assembly of the Handle is introduced. In the area of the recording, the handle points in her Exterior wall made a breakthrough. In this breakthrough lies in the recording inserted container, the container surface carrying the buttons. The Button can be flush with the breakthrough of the handle. The Button of the container can breakthrough the handle as well overhang and / or the adjacent areas of the outer wall of the handle here partially overlap on one or more pages of the button. Of the Breakthrough can be provided in the handle of the handle, or else be in two parts, so that a part of the breakthrough in the handle of the handle is located and a second part of the breakthrough lies in the handle cover of the handle. The container is preferably waterproof, so that the sensitive Switching elements are protected from access to water and it is not too Short circuits may occur when moisture penetrates. By the arrangement the switching elements in a waterproof container, are also the Manufacturing costs significantly reduced, since the elaborate casting of the separate Interior of the handle deleted.

The button of the container is directly on the inner surface of the handle arranged so that an actuation of the switching elements already by a Touching the button when the user's hand grips the handle, is performed. The handle must therefore no longer be pulled to the Entsichernungsvorgang the lock trigger. There is the advantage that the Reaction time of the system significantly reduced to the expressed access request becomes.

Particularly advantageous according to claim 3, it is when the intended Switching elements are electronically operating pressure switching elements. These electronically operating pressure switching elements have the advantage that the Schaltweg is very short, and that this time gain is achieved, the one fast response of the control electronics of the locking system to that of the user expressed desire of access to the vehicle allows.

It may still be useful to another breakthrough in the handle in which an additional sensor for securing the locking system is arranged. This further breakthrough may also be e.g. on another page be arranged the handle.
