Abstract

The invention relates to a keyless entry system comprising a support such as a door, a movable handle fixed to said support, a locking/unlocking mechanism and an electronic unit including an identification means assigned to at least one user and a reader arranged in such a way that, when access is authorized, said locking/unlocking system is activated, the keyless entry system being characterized by the fact that it comprises an energy converter adapted to convert the mechanical energy resulting from a movement of said handle by a user into an electrical energy for activating a query process by said reader.

Description

Keyless entry system
Field of the invention
The present invention relates to a keyless entry system operated with bidirectional wireless data transmission between a data carrier (e.g. a transponder) and a locking/unlocking mechanism which includes a reader.
The invention may be used in all environments but is particularly adapted for house doors or more generally for any door in a environment where no electrical source of energy is available.
State of the art
Keyless entry systems as defined above are disclosed in the following patent documents : US 6 181 024 B1 (Bosch), EP 1 138 853 A2 (Valeo Securite Habitacle) and DE 198 16 603 C1 (Bosch). The system of US 6 181 024 B1 has a door handle which can be pivoted in one end area, while a push button which is provided in its other end area can be operated by light pressure on the door handle. By operating the push button, a transmitter unit is initialized to initiate a query to a query unit. The query unit includes a transponder assigned to a user. If access is authorized, a door lock on the door is unlocked. By then pulling the door handle the door is opened. The keyless entry system described above, together with the keyless entry systems disclosed in EP 1 138 853 A2 and DE 198 16 603 C1 are designed for vehicles. The energy required for activating the reader is provided by the vehicle battery. There is however other environments where no electrical source of energy is available for activating the reader, e.g. a house door. In such a situation, a specific source of energy, e.g. a battery, has to be mounted in or close to the door.
Summary of the invention An objective of the invention is to avoid the use of a specific, time-limited, source of energy, e.g. a battery, for activating the reader. This is achieved with a keyless entry system as defined in claim 1. Preferred embodiments of the invention are defined in dependent claims 2 to 4. In the present text the expression locking/unlocking mechanism has to be understood as a means adapted to lock or unlock the door lock. If the lock is unlocked the support (e.g. a door) still needs to be pushed or pulled in order to be opened.
The identification means may advantageously be a RF1D device which includes a transponder located on the user.
Alternatively the identification means may comprise a biometric sensor, e.g. a fingerprint detector located on the handle.
Detailed description of the invention
The figure shows a flow chart summarizing the use of a keyless entry system according to the invention. In the present example, the support is a door which includes a lock. The lock can be locked or unlocked by a commonly used locking/unlocking mechanism, e.g. comprising bolts.
An electronic quiry unit (known in the art) is located either in the door or close to the door.
An authorized user is wearing a transponder (known in the art). The user first activates the handle. By doing so, the mechanical energy resulting from the movement of the handle is converted into an electrical energy which activates the electronic quiry unit. The energy conversion may be obtained by any known converter.
If access is authorized, the lock is unlocked. Preferably the energy used for the unlocking process is derived from the mechanical energy induced by the first movement of the handle.
The user finally reactivates the handle and by pulling or pushing it the door opens.
In another embodiment (not illustrated) the user only needs to activate the handle once. More precisely the handle is first moved on a relatively short distance (or angle if the handle rotates). This first movement activates the quiry unit and the unlocking process in the same manner as previously defined in the above cited embodiment. By moving further the handle and pulling or pushing it the door opens.

Claims

Claims
1. Keyless entry system comprising a support such as a door, a movable handle fixed to said support, a locking/unlocking mechanism and an electronic unit including an identification means assigned to at least one user and a reader arranged in such a way that, when access is authorized, said locking/unlocking system is activated, the keyless entry system being characterized by the fact that it comprises an energy converter adapted to convert the mechanical energy resulting from a movement of said handle by a user into an electrical energy for activating a query process by said reader.
2. Keyless entry system according to the previous claim wherein said identification means is a RFID device, including for instance a transponder adapted to be located on a user.
3. Keyless entry system according to claim 1 wherein said identification means comprises a fingerprint detector which, preferably, is located on the handle.
4. Keyless entry system according to any of the previous claims wherein said locking/unlocking mechanism is at least partially an electromechanical mechanism.
5. Keyless entry system according to the previous claim wherein said locking/unlocking mechanism is entirely an electromechanical mechanism.
6. Keyless entry system according to any of the previous claims wherein said converter is also adapted to convert the mechanical energy resulting from a movement of said handle by a user into an electrical energy for at least partially activating the unlocking process.
7. Use of a keyless entry system as defined in claim 1 comprising the following steps : - 1st activation of the handle by a user causing thereby the initiation of the reader, - Query process, - If access is authorized, unlocking of the locking/unlocking mechanism, - 2nd activation of the handle by the user and opening of the door.
8. Use of a keyless entry system as defined in claim 1 comprising the following steps : - Initiating a movement of the handle causing thereby the initiation of the reader, - Query process, - If access is authorized, unlocking of the locking/unlocking mechanism, - Ending the movement of the handle causing thereby the opening of the door.
