Description

TECHNICAL FIELD The present invention relates to an electromagnet lock device that locks and unlocks a door of an entrance or the like in a dwelling unit, an office, or the like by using an electromagnetic force, an attraction force, or the like of an electromagnet.

Conventionally, the key was presumed to use a deadbolt, a thumbturn was used from the inside, a cylinder lock etc. was used from the outside, and the deadbolt was pulled out and retracted by rotating the key to open and close the lock . In recent years, some locks have been increased or have a complicated structure to prevent crimes such as picking, etc. Could not be prevented.

The conventional locking and unlocking method using dead bolts is characterized by unlocking and unlocking by using the electromagnetic force and suction force of an electromagnet. It is an object to provide an electromagnetic lock device that can prevent the electromagnetic lock.

Means to solve the problem

The door is locked and unlocked by using the electromagnetic force and the attractive force of the electromagnet, and the electromagnet is built into the door stop portion of the door frame or inside the door body. As described above, by locking and unlocking with the electromagnetic force and the attractive force of the electromagnet, it is possible to prevent the picking action and the cutting or breaking of the deadbolt and the entry into the room. Further, in order to prevent damage at the time of opening / closing or at the time of collision, the electromagnet can be installed on an existing door by covering the electromagnet with a steel plate or the like and fixing the electromagnet to a door stop. Also, for a member such as aluminum made of a material other than steel such as an aluminum door frame to which the effect such as the electromagnetic force and the attracting force of the electromagnet does not work, a receiving metal fitting is attached to a member in contact with the electromagnet. Locking and unlocking can be performed by using a switch in the room or by remote control from the outside (remote control, etc.), locking and unlocking using a cylinder lock or thumb turn, separate or mixed numeric key lock, card lock, fingerprint lock, etc. And let it work.

The best mode of the present invention will be described with reference to FIGS. An electromagnet (10) is built in the door stop (5) of the door frame of FIG. 1 or inside the door (4) of FIG. In addition, when it is attached to an existing entrance, entrance, or the like, an electromagnet is attached to the door stop portion (5) as shown in FIG. 3, and the electromagnet (1) is covered with a steel plate or the like to prevent damage during opening / closing or collision. Also, for a member such as aluminum, for which the door frame or the like to be attached is not made of steel and the electromagnet is not effective, such as an electromagnetic force and an attractive force, a metal fitting (15) as shown in FIG. Attach. The receiving bracket is attached to the door when an electromagnet is attached to the door stop portion as shown in FIGS. 1 and 3, and is attached to the door stop portion when the electromagnet is built in the door as shown in FIG. In addition, when the door or the like cannot be in close contact with the electromagnet due to distortion, irregularities, or the like in the door or the frame, a shock absorber or the like is attached between the door or the frame and the electromagnet, and is closely attached.

Locking and unlocking can be performed by using a switch in the room or by remote control (remote control or the like) from the outside, or by using the thumb turn (11) or cylinder lock (12) shown in FIG. There is a numeric keypad lock that changes the arrangement of numbers each time, a card lock system using a special card, a fingerprint lock that unlocks by identifying and authenticating the individual with a fingerprint, etc. There are various ways to make it work. As shown in FIG. 8, a power source for locking and unlocking is provided with a power source storage box (2) on the indoor side and connected to the electromagnet (1). The power supply has a built-in battery so that it can respond to disasters such as a power outage, and has a power-off unlocking device and a safety device. When an electromagnetic lock device is attached to a new door or the like, the storage box (2) for the power supply and the like is to be installed in an appropriate place, and a remote control (remote control and the like) for locking and unlocking from outside is provided. Power supply etc. shall be installed indoors. When locking and unlocking from the indoor side, a switch (8), a thumb turn (11) and the like are used. In addition, when locking and unlocking is performed from the outside, it is performed by remote control (such as a remote controller) using the operation keys or the like or by the cylinder lock (12) as described above. For this reason, a remote control system is also built in the storage box (2) such as a power supply. When the door is closed, the door (4) and the electromagnet come into contact with each other (9) when the door is closed as shown in FIG. Since the door is locked by the electromagnetic force of an electromagnet or the like, the electromagnet (1) uses a member having sufficient electromagnetic force, adsorption force, durability and the like to open and lock. The mounting range of the electromagnet depends on the performance of the electromagnet to be used, such as the one that comes into contact with the entire height of the door or the one that is only partially mounted.

In addition to the above, the shape of the fitting can be set or used in the case of a sliding door shape as shown in FIGS. 5, 6, and 7, or in other shapes. As described above, since the locking and unlocking are performed by the electromagnetic force and the attractive force of the electromagnet, the dead bolt (13) and the latch bolt (14) in FIG. 10 can be eliminated, and criminal acts such as picking can be prevented. Can be.

The invention's effect

According to the present invention, the conventional locking and unlocking method using a deadbolt enables the unlocking and unlocking by using an electromagnetic force, an attraction force, and the like of an electromagnet. Recently, the number of activities such as picking, entry into the room by cutting or destroying a deadbolt, turning of a thumb turn, and the like are increasing, and there are various types of security goods, but none of them can be reliably prevented. However, the electromagnet lock device of the present invention can be attached to an existing door in addition to a newly built-in shape, and can be attached to an opening door, a sliding door, and various other opening / closing doors, so that the above criminal acts can be further prevented.
