Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic key made of synthetic resin that can be magnetized from the outside.

[Conventional technology]

2. Description of the Related Art Conventionally, at the front desk of a hotel or the like, a key for a room is given to a guest, and the key returned by the guest is received.

[Problem that the invention seeks to solve]

By the way, with the above-mentioned conventional keys, when a customer receives the key when going out, someone other than a person skilled in the art may take the key left at the front desk and illegally break in.

In addition, when a room is occupied by more than 2 Å, especially when many people are using the room, even if all the users of the room leave the room, they do not leave the key at the front desk when they are in the hotel. I had decided. Therefore, when a person other than the owner of the key wants to enter the room, there is an inconvenience in that the user must go to the owner of the key and take the key each time.

Furthermore, if the key is lost, the key for the room and the lock on the door must be replaced with a new one, which poses a problem in that it takes time and money to replace the key.

The present invention was made in order to solve the above-mentioned problems, and an object of the present invention is to obtain a magnetic key made of synthetic resin and encapsulating an unmagnetized magnetic material that can be magnetized from the outside of the key.

[Means for solving problems]

The magnetic key according to the present invention has a key consisting of a gripping part and a push-in part made of a synthetic resin material, and has a magnetic key that can be magnetized from the outside of the key to an N pole or an S pole according to a required magnetic back code. Magnetized magnetic bodies are arranged at a predetermined pitch in the insertion section.

[Effect]

In this invention, an unmagnetized magnetic material is sealed in advance in the push-in part of a key made of synthetic VA sushi, and a magnetic key is obtained by magnetizing the magnetic material from the outside of the key according to a magnetic pattern code. reactor.

〔Example〕

Figures 1 (ag, b) and (c) show an embodiment of the present invention, where Figure 1 (a) is a front view and Figure 1 (b) 1.
is a plan view, and FIG. 1(C) is a sectional view taken along I-IMP of FIG. 1(b). In these figures, 1 indicates the entire magnetic key, which is made of a non-magnetic material such as nylon and an insulating synthetic resin material, and is further mixed with a conductive material such as carbon black to prevent static electricity from being applied to the human body. It is formed to have a resistance value of ~10 MΩ so as not to receive a shock.

2 is a gripping portion of the magnetic key 1; 3 is an insertion portion for pushing the magnetic key 1 into the lock; 4 is a key groove of the magnetic key 1; and 5 is a magnetic key for reinforcing the magnetic key 1 itself. It is a reinforcing material sealed inside the 1, and is made of non-magnetic metal or the like.

6 is an unmagnetized magnetic body buried at a predetermined pitch on both sides or one side of the insertion portion 30 of the magnetic key 1; 7 is a bottomed hole for embedding the magnetic body 6; 8 is the bottomed hole A recess 9 formed in the hole 7 is a lid that is placed over the recess 8 to enclose the magnetic body 6, and is made of the same material as the magnetic key 1.

When manufacturing the magnetic key 1, the grip portion 2 and the insertion portion 3 are integrally molded using a synthetic resin molding machine, a press machine, or the like. Next, after the magnetic material 6 without mat is embedded in the bottomed hole 7, the recess 8 is covered with a lid 9 and sealed.

Next, as shown in FIG. 2, Nu-1 and Si are magnetized by the M magnetic machine 11 according to the required magnetic pattern code.
Alternatively, set a space that is not magnetized.

When using the magnetic key 1 manufactured as described above, first, when the magnetic key 1 is inserted into the lock of the door, the magnetic body 6 attached to the magnetic key 1 is detected by the magnetic reader installed in the lock. The N pole, S pole, and space without magnetic poles of the magnetized permanent magnet are detected and read, the read signal is sent to the central control room, and the magnetic pattern code of magnetic key 1 and the magnetic pattern code are registered in the central control room. If the pattern code of the door matches, the central control room can unlock the electric lock of the door and open the door.

On the other hand, if the magnetic pattern code of the magnetic key 1 inserted into the door lock is different from the pattern code of the door, it will be known that the door has been unlocked illegally, so the central control room will not be able to send a signal to unlock the electric lock. This prevents unauthorized unlocking.

In this way, when checking in at a hotel or the like, magnetic keys 1 are handed out at the front desk for the number of people using the same room, and when checking out, they are collected from everyone. When the lock is unlocked, unauthorized unlocking can be prevented by discarding all used magnetic keys 1 and switching to magnetic keys 1 with a new maternal pattern code. At this time, the magnetic pattern code on the central control room door will also be changed.

Further, even when the magnetic key 1 is lost while using the room, all the remaining plurality of keys are discarded and a new magnetic key 1 with a magnetic pattern code is provided in the same manner as above.

FIGS. 3(a) and 3(b) show another embodiment of the present invention, and are sectional views showing the shape of the key insertion part.
FIG. 3(a) shows a chevron, FIG. 3(b) shows a trapezoid, and the same reference numerals as in FIG. 1 indicate the same or corresponding parts.

1. In the embodiments shown in FIGS. 1 and 3, the magnetic body 6 is
The axes of the magnetic bodies 6 are made perpendicular to the plane of the magnetic key 1 in order to arrange them in rows, but in the case of -rows, they are made parallel to the plane of the magnetic keys 1 and the length of the magnetic bodies 6 is made a little longer. , making it easier to apply magnetization from the outside. Furthermore, even better magnetization can be achieved by heating and press-fitting magnetic powder only into the synthetic resin portions on both sides of the magnetic body 6 to be magnetized, and then magnetizing. reactor.

Further, when the magnetic key 1 is held while the human body is charged with static electricity, the static electricity of the human body flows from the fingers to the conductive material of the magnetic key 1, and the entire magnetic key 1 is charged. Next, when the magnetic key 1 is pushed into the lock, static electricity from the human body flows through the conductive material of the magnetic key 1 to the grounded door. However, the human body is not subject to electrostatic shift because the conductive material mixed in the autogenous tree pus has the required resistance value.

〔Effect of the invention〕

As explained above, the present invention is characterized in that a key consisting of a gripping part and an insertion part is formed of a synthetic resin material, and the key is magnetized to an N pole or S pole from the outside according to a required magnetic pattern code. Because the magnetic material is arranged at a predetermined pitch in the insertion part, it is easy to process and manufacture keys, and it is lightweight (and inexpensive, so even if one of the spare keys is lost, the remaining keys can be exhausted) This has the advantage that unauthorized M locks can be completely prevented by providing a key with a new magnetic pattern code.
