Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electric locking/unlocking device, and more particularly to an improvement of an electric locking/unlocking device for a sliding door.

[Prior Art] Electric locking and unlocking devices that open and close gates by remote control from an electric lock operation panel installed in a dwelling unit are widely used, and devices for sliding doors have also been developed.

An electric lock like the one shown in 2 has a structure in which the lock solenoid performs locking and unlocking operations by alternately energizing in reverse, and also displays the locking, unlocking, and open status of the door on the electric lock operation panel. This has been accomplished.

For example, if you operate an electric lock with the door open, the electric lock will be locked, but the door will remain open, and the electric lock operation panel will remain open. As for the display, the door open indicator and lock indicator will light up.

In general, it is often not possible to directly see a gate with an electric lock from the electric lock operation panel, so if you check only that the lock indicator is lit without looking at the door open indicator, you may mistakenly think that it is locked. It becomes easier.

In order to prevent such erroneous operations, an electric locking/unlocking device that can be locked and unlocked only when the gate is closed is disclosed in Japanese Patent Laid-Open No. 18865/1983.

FIG. 6 is an explanatory diagram showing its configuration.

In the figure, A is a power transmission unit divided into two parts,
A power transmission unit 102 in which a coil 1021:l is wound around a core 102a is provided on the door 104 side, and the other core 1
A current transmission unit 103 having a coil 1031) wound around the current transmission unit 103 is provided on the door frame 105 side.

Therefore, when @104 is closed, the power transmission units) 102 and 103 are connected in a matching manner, and the cores 102a,
A magnetic path is formed by the coil 103a, and electric power for locking and unlocking the coil 1031) is transmitted to the coil 102b. This power is applied to the electric lock 100 via the drive circuit 101 to drive it. As a result, the actuator inside the electric lock causes the deadbolt to protrude and fit into the strike 105a of the door frame 105, thereby locking the door.

In addition, if the door 104 is opened, the power transmission unit) 1
No power is transmitted between 02 and 103, and locking and unlocking operations are not performed.

However, in the electric lock/unlock device with the above configuration, power from the power transmission unit is input to the drive circuit, and the output of the drive circuit drives the drive actuator of the electric lock, so there is a large loss in power transmission, and the structure is becomes complicated.

From this point of view, there is a need for the development of an electric locking/unlocking device that has a simple structure, has low power loss, and is free from erroneous locking/unlocking operations.

[Problems to be Solved by the Invention] The present invention proposed to solve the above-mentioned problems is capable of locking only when the gate is closed, has a simple structure, and has a configuration with low power loss. The purpose of this invention is to provide an electric locking/unlocking device that is free from erroneous operation.

[Means for Solving the Problems] The present invention proposed to achieve the above object has a coil wound on one side, a cutout on the other side, and a permanent magnet inside the cutout. The yoke, which forms a stator part in which a rotor connected to an actuator for locking and unlocking is rotatably fitted, is separated into a coil winding part and a coater solenoid part, one of which is attached to the inner surface of the sliding door. One door is attached to the other, and the other is attached to the corresponding location on the door frame.

[Function] According to the electric locking/unlocking device of the present invention, when the sliding door is closed, the coil winding portion of the yoke, which had been separated, and the coater solenoid portion are aligned and connected to form a magnetic path. Therefore, by alternately reversing the polarity of the conduction to the coil winding portion, the actuator connected to the rotor of the rotary solenoid portion is driven to lock and unlock the sliding door.

Therefore, locking and unlocking operations are performed only when the sliding door is closed, eliminating the need for energizing operations when opening the door.
Locking/unlocking operation becomes reliable.

[Example] Fig. 1 and Fig. 2 are diagrams explaining the operating principle of the electric locking/unlocking device of the present invention.

In FIG. 1, A and B are a coil winding part and a rotary solenoid part, which are constructed by separating a normal rotary solenoid into two parts at the yoke part.

In this coil winding part A, a coil 1 is wound around a U-shaped core 11, and in one rotary solenoid part B, a rotor 2 is provided in a notch 12c of a stator 12.12, and the rotor 2 is a permanent magnet. It has a structure that is rotatable around a rotating shaft 2a.

That is, the core 1 of the coil winding section A and the stator 12.12 of the rotary solenoid section B are integrated and correspond to the yoke of the rotary solenoid.

The coil winding part A is provided on the door frame 3 side, and the rotary solenoid part B is attached at a location corresponding to the coil winding part A on the sliding door 4 side.

In the coil winding part A and rotary solenoid part B having such a structure, when the sliding door 4 is closed, the joint surfaces 11a and 11b of the core 11 and the joint surface 12a of the stator 12°12,
12b are attached for matching connection.

FIG. 2 is a diagram showing a state in which the sliding door 4 is closed.

When the coil 1 is energized to lock or unlock using an electric lock operation panel (not shown), the core 11 and stator 12.1
2, a magnetic circuit is constructed, and the rotor 2 receives rotational torque and rotates.

Furthermore, by applying electricity of the opposite polarity, the rotor rotates in the opposite direction, driving an actuator connected to the rotor shaft 2a to perform a locking/unlocking operation.

On the other hand, as shown in FIG. 1, when the sliding door 4 is open, no magnetic circuit is formed between the core 11 and the stator 12, 12, so even if the coil 1 is energized to lock or unlock, the rotor 2 is not driven and locking/unlocking operations are not performed.

FIGS. 3 and 4 are diagrams showing embodiments of the present invention.

A coil winding part A is attached to the door frame 3 side.

On the other hand, on the sliding door 4 side, a link 5 is attached to the rotor shaft 2a of the rotary solenoid part B, and the protrusion 5a of the link 5 engages with the recessed fitting part 6a of the slider 6. As the rotor 2 rotates, the link 5 moves. The slider 6 has a structure in which it rotates and slides up and down.

Further, a foot member 7 is rotatably attached around a rotating shaft 8, and an elongated hole in the foot member 7 provides an escape hole. +) is fitted into the protrusion 61 of the slider 6.

Therefore, in response to upward or downward sliding of the slider 6,
The foot (off) rotates to the left or right around the rotation axis 8.

When rotating to the left, as shown in FIG.
When it is inserted and the lock is turned once, and when it is rotated clockwise, it will be unlocked.

FIG. 5 shows the rotation angle of the rotor 2 of the rotary solenoid used in the present invention, with the rotor 2 in a horizontal state as 0 degrees, clockwise rotation as positive, and counterclockwise rotation as negative. It is a torque characteristic diagram with respect to a rotation angle.

Normally, when the tread member 7 provided on the sliding door 4 side is fitted into the engaging portion (not shown) of the door frame 3 and locked, or when the door is unlocked in a reverse direction, the tread member 7 engages with the tread member 7. It is possible that lateral pressure is applied to the foot member due to the displacement of the part (not shown), and this I
In order to lock and unlock the door against the II pressure, a flat torque characteristic is required to rotate the contact portion t-off against the side pressure.

Further, the rotational torque of the rotary solenoid is proportional to the rate of change of the magnetic flux flowing between the rotor and the stator.

In FIG. 1, the gap 12 between the stators 12.12
d is narrow and the cap 12e is wide, the rate of change of the magnetic flux flowing through the core 11 and stator 12, 12 as the rotor 2 rotates is averaged, and as shown in (a) in FIG. , ) are obtained, and the lateral pressure of the pedal member is dealt with.

Furthermore, the torque characteristics when the rotor 2 is operated manually, that is, in a non-excited state, are shown in (1) in FIG. When rotating clockwise, the lock operates to the right rotation limit, and when rotating counterclockwise, it returns to the left rotation limit.
The rotor 2 does not stop midway, and the operational feel is improved.

[Effects of the Invention] The electric locking/unlocking device of the present invention does not require electrical wiring for energizing the rotary solenoid on the sliding door side, making it easy to install, simple in structure, and easy to operate. A convenient electric lock/unlock device can be provided.

In addition, locking and unlocking operations are performed only when the sliding door is closed, so even if the door is opened electrically, it will not operate, eliminating erroneous operations and easily providing a highly reliable electric locking and unlocking device.
