Abstract

PURPOSE:To permit a door to be unlocked only when a pet with a wireless signal transmitter to send out a radio signal with ID codes comes near the door by a method in which ID codes are registered on the wireless signal receiver side. CONSTITUTION:A passage sensor 6 consisting of a heat ray sensor or photo sensor for confirming the passage of pet is provided on the edge of a door side 3a or on the end of a door 3. When a passage sensor 6 is connected to an electric key 4 by signal line l2 and the passage of pet is confirmed, the key 4 unlocked is locked. ID codes from a wireless signal transmitter 1 attached to the pet 7 is registered on the wireless signal receiver 2 side. The passage of only specified pets can thus be allowed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a system in which a door that can be opened and closed can be locked and unlocked wirelessly, allowing pets such as cats and dogs to freely enter and exit.

[Prior Art] In order to allow pets such as dogs and cats to freely enter and exit the home, there are some devices that have an opening/closing door for small pets such as the entrance door. Since there is no locking mechanism, pets of other people can come and go freely.
There were also problems with airtightness and security.

[Problems to be Solved by the Invention] The present invention has been made in view of the above circumstances, and proposes an electric lock system for pets that allows only the pets owned by the pet to enter and exit freely.

[Function] According to the present invention, when an ID code is registered on the wireless receiver side, only a pet equipped with a wireless transmitter that transmits a radio wave signal with the ID code attached can approach the door. The door is unlocked when the door is opened, and it is automatically locked after the pet has passed, which prevents pets belonging to other people from entering and exiting, and is also safe from a crime prevention perspective.

[Embodiment] An embodiment of the system of the present invention will be described below with reference to the attached drawings.

In Fig. 1, 1 is a pendant-type wireless transmitter that can be attached to the neck of a pet 7 such as a dog or cat, and 5 is an entrance door with an opening/closing door 3 for pets at the bottom. be.

The pet opening 313 provided below the entrance door 6 can be locked and unlocked using the electric lock 4, allowing you to open and close it! II
3 and the edge of the doorway 3a are provided with a passage detection means 6 composed of a heat ray sensor, a light sensor, etc. to confirm the passage of a pet, and this passage detection means 6 is used as a signal line! 2 is connected to an electric lock 4, and when the passage of a pet is confirmed, the unlocked electric lock 4 is locked.

A wireless receiver 2 is additionally connected to the electric lock 4 via a signal line 11, and a house code and ID code are registered and set in advance to this wireless receiver 2 to prevent interference with other wireless systems. It is now possible.

Figure 2 shows a wireless transmitter 1 and a wireless receiver 2.
The configuration of the internal circuit is shown in a block diagram.

The wireless transmitter 1 has a house code and an ID code setting #]C, ID, and when the house code and ID code are set, the signal processing unit IA unlocks the house code and ID code. A signal is additionally generated and a radio wave signal is transmitted from the antenna IE of the wireless transmitter IB. Note that IF is a battery for supplying power to each internal circuit of the wireless transmitter 1, and the wireless transmitter 1 is configured to be able to transmit radio signals constantly or intermittently using this battery.

One of the wireless receivers 2 includes a front end unit 2Atj! for receiving the radio signal transmitted from the wireless transmitter III! Furthermore, the radio wave signal received by this front end section 2A is converted into an electrical signal and sent to the signal processing section 2B.

The signal processing section 2B decodes the radio signal and determines whether the codes set by the house code setting section 2F and the ID code setting section 2E match, and if they match,
The reception indicator light 2C is turned on, the internal contact 2D is closed at the same time, and an unlocking signal is sent to the electric lock 4. Upon receiving this signal, the electric lock 4 disengages the deadbolt 4a and releases the opening/closing 1j3. The structure is such that the door is locked after the passage detection means 6 detects that the pet 7 has passed through the opening/closing 113.

The wireless receiver 2 includes a power supply circuit fM32H that receives 100 cm of commercial power and generates power for the internal circuit, a backup rechargeable battery 2J that is charged by the power supply circuit section 2H, and a radio wave signal that is received by the front end section 2A. Receiving sensitivity switching adjustment means 2 for adjusting the sensitivity level of
It is equipped with G.

As shown in FIG. 4, the opening/closing door s3 may have a structure in which the opening/closing door 3 is held in a position where the door opening 3a is closed by a spring force when the door is unlocked, and in that case, the pet 7
If the pet presses the opening/closing 113 with their body, the opening/closing 313 is opened in the intrusion direction to allow entry and exit, and after the pet has passed, the passage detection means 6 sends a locking signal to the electric lock 4 and the opening/closing door 3 is automatically closed. Therefore, there is no need for a means to close the door, but in order to make it even more convenient for the pet 7 to go in and out, a solenoid (not shown) can be used to open and close the door 1! ! 3 is slightly opened in one direction, and after the passage detection means 6 detects that the pet 7 has entered and exited and passed through the opening/closing door s3, the opened opening/closing door 3 is returned to the position where the door opening 3a is closed, and then the electric lock is set. 4 may be constructed by providing a door closing means for locking the door (lI requirement 3).

According to the system of the present invention, the wireless transmitter 1 attached to the pet 7 constantly or intermittently transmits a radio wave signal with an ID code registered on the wireless receiver W2 side. Just by registering the ID code transmitted from the wireless transmitter l attached to the wireless receiver 1 on the wireless receiver 12 side, when the pet 7 with the wireless transmitter 1 attached enters the radio wave detection area E of the wireless receiver @2. The electric lock 4 is unlocked, but if the pet 7 moves out of the radio wave detection area E, its radio signal will not be detected. Therefore, the electric lock 4 can remain locked, which is safe from a crime prevention standpoint, and prevents other people from entering. This also prevents pets from entering the residence.

In addition, in such a system, the wireless receiver 2 is provided with a receiving sensitivity switching adjustment means 2G that can switch and adjust the receiving sensitivity 1, and the receiving sensitivity of the wireless receiver is reduced during normal electric lock control, and the pet 7 is If you increase the reception sensitivity when searching, the reception indicator light 2C will be on as long as the pet 7 is within the area where the radio waves can reach within the wireless system.
It is very convenient because the presence of the device can be known by lighting or blinking (Claim 2).

[Effects of the Invention] As can be understood from the above explanation, according to the present invention, only a specific pet can enter and exit using a wireless method without a signal line, so it is possible to prevent pets owned by others from entering. , a safe electric lock system can be obtained in terms of crime prevention (
Claim 1).

Furthermore, the device equipped with a receiving sensitivity switching adjustment means is convenient because it can be used by lowering the sensitivity during normal electric lock control and increasing the sensitivity when searching for a pet (M requirement 2).

Furthermore, in claim 3, after the opening/closing I11 which is unlocked by the electric lock is checked, the door can be closed by the door closing means and then locked, so that a very convenient electric lock system can be obtained.
