Further details, advantages and features of the object of the present invention follow from the following description of the associated drawings which serve to explain—in the form of working examples—the doors according to the present invention. The drawings show:
The access device for pets denoted by 2 as a whole in
The access device has a door constituted by a flap 4 hanging at a horizontally disposed hinge, which flap is fixed to a frame 6 through the hinge. The flap is arranged in such manner as to be flippable upwards to both sides, thereby providing access. An electronic board 8 arranged in the frame 6 primarily controls the locking system 10. However, the latter can also be controlled manually by keeping the flap constantly locked or constantly open. It is possible to have the constantly open or locked state for one direction. In the present working example, the locking mechanism 10 exhibits a turn knob that in its various positions allows or requires an electrical release. On the access device this is subsequently displayed on display 14, which in the working example consists of two LEDs.
In the working example, the electronic board is supplied with electric power from a rechargeable battery, the rechargeable battery 22 being charged by means of an external power supply 18. The power supply is connected with the access device by means of plug 20.
It is important for the invention that the electronic board 8 comprises a reader device for transponders that reads out the code from a transponder chip located in the vicinity of the reader unit and compares the code with a list stored in electronic board 8. Alternatively, the reader unit can also be arranged separate from the electronic board, e.g. if required by spatial constraints. The reader unit is connected with an antenna device 24 that communicates with the transponder. Advantageously, the transponder will be implanted in a pet, but it is also possible to carry the transponder e.g. on a collar or attach the same to an ear.
Initially, the list stored on the electronic board 8 is empty, i.e. no access admission has been granted to any pets as initial setting. In order to grant admission to a pet having a corresponding, so far unknown transponder, the pet can be placed in the influence range of the antenna. By actuating the simple switch 12 designed as a push-button, the transponder code of the transponder arranged at or within the pet is read in and added to the list of admitted pets. The entry is confirmed with a signal of display 14 (blinking). In a next approach of this pet, upon comparison with the stored list this particular pet will be recognized and admitted according to the preset permissions (unidirectional or bidirectional admission). Hence, the locking mechanism 10 will be opened insofar as its turn-knob is set to allow for an electrical opening.
However, according to the present working example, in case of a power failure the locking mechanism can be overwritten by a release at least in the outbound direction, optionally also in the inbound direction, so that the pet is not permanently trapped in case of power failure.
In the present working example, the access device 2 further comprises an approach sensor 16. This is because for reasons of saving electrical power the reader device shall remain inactive until the approach sensor 16 detects an object in its proximity. Only then will the electronic circuitry be switched on and the process of reading and comparing the read in transponder code with the list be carried out and a decision be reached concerning the admission of the pet carrying the transponder. Alternatively, instead of the approach sensor 16, a touch sensor can be built into the flap of the access device then requiring that the animal tries to pass through the door, and only thereafter triggering the reading process by this touch sensor. However, the function is the same.
