Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door device having an electric lock mechanism and enabling remote control.

[0002]

2. Description of the Related Art A sliding door is provided with a suspension car at its upper end, and the suspension car can be opened and closed by moving on the upper rail. Here, if the upper rail is slightly inclined, the sliding door which is pushed and opened by hand becomes a semi-automatic type which can be closed by its own weight by itself. By the way, such a sliding door is used indoors, and is often not necessarily required to have a lock mechanism because it is attached to an entrance of a room.

However, there are many cases where it is difficult to freely enter and exit a room or an office entrance provided indoors. For example, in a financial office such as a bank or a securities company, there is a case where entry by anyone other than the related parties is prohibited.
Also, in nursing homes where elderly people with dementia are cared for, a compartment closing system is required to ensure safety and control behavior and prevent them from leaving the room freely.

Therefore, it is necessary to provide a locking mechanism in the sliding door device. However, it is troublesome if a person performs locking and unlocking operations for each sliding door, so it is possible to employ an electrically controlled locking device. It is. However, when a locking device is mounted on the sliding door, it is necessary to supply power to the sliding door from the frame, and this electric wiring is troublesome and at the same time, there are cases where the locking device does not operate due to an electrical trouble. easy.

[0005]

As described above, the conventional sliding door has the above-mentioned problems. The problem to be solved by the present invention is this problem. To provide a sliding door device that can be locked and unlocked by electric control and has a lock mechanism with simple electric wiring.

[0006]

SUMMARY OF THE INVENTION A sliding door device provided with a lock mechanism according to the present invention has a locking device mounted on an upper rail side, the locking device provided with a dead bolt which projects and retracts, and a protruding dead bolt is provided on the sliding door side. The sliding door is locked by fitting into the fitting groove formed in the sliding door. The dead bolt has a structure that can be protruded or retracted electrically, and can also be manually operated. The deadbolt can then be configured to be controlled remotely via electrical signals.

[0007] One fitting groove is provided on the sliding door side,
The specific location of the fitting groove is not limited, and it may be the upper end of the sliding door, or a receiving member having the fitting groove formed on the suspension wheel. When the dead bolt projects, the position of the sliding door is detected by a sensor so as to fit into the fitting groove, that is, so that the dead bolt projects only at the position where the dead bolt fits. Sent. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

1 is an external view showing a sliding door device. The sliding door 1 is suspended from an upper rail and slides to open and close an entrance. An inspection panel 2 is provided at an upper part of the entrance to cover the upper rail for suspending the sliding door 1, a hanging vehicle that moves on the upper rail, and a brake device and the like.

FIGS. 2 and 3 show an embodiment of a lock device to be mounted on a sliding door according to the present invention. A suspension wheel 3 is attached to the upper end of the sliding door 1, and a roller 4 provided on the suspension wheel 3 can roll on an upper rail 5. If the sliding door device is of a semi-automatic type, the upper rail 5 is slightly inclined, and the sliding door 1 pushed and opened by hand can be closed by the action of its own weight.

Although not shown, a pinion is provided along the upper rail side, and a pinion that meshes with the rack is attached to the sliding door side, and has a brake function to reduce an impact when the sliding door is closed. Can be engaged with the rack. In addition, although a specific configuration having other functions as the sliding door device is not limited, the present invention includes the lock device 6 on the upper rail side.

Here, the specific internal structure of the lock device 6 is not limited, but the lock device 6 is configured such that the dead bolt 7 is protruded and retracted by the action of the electromagnet. Generally, a solenoid is built in as a means for projecting the dead bolt 7, and when the electricity is turned on, the dead bolt 7 is retracted.

A receiving member 8 is fixed to the suspension vehicle 3,
The receiving member 8 is formed with a fitting groove 9 which is open at the top. The dead bolt 7 of the lock device 6 is fitted into the fitting groove 9 by projecting, and as a result, the sliding door 1 is locked and cannot be opened. Turn off the power to the lock device 6
By doing so, the coil spring of the solenoid extends and the dead bolt 7 always projects, and the tip of the dead bolt can be fitted in the fitting groove, so that the reliability of the lock device is high.

By the way, the lock device 6 is turned on and unlocked by inputting a switch, for example, a password provided near the entrance, and the sliding door can be pushed open by hand. And if it is semi-automatic, it closes by itself,
When the lock device is completely closed, the power of the lock device is turned off and locked. That is, the magnet 10 is attached to the receiving member 8, and when the sliding door 1 is completely closed, the magnetism of the magnet 10 is sensed and the lock device 6 operates. Here, a magnetic sensor 11 is provided in the lock device 6, and the magnetic sensor 11 detects that the sliding door 1 is closed and the magnet 10 is at a predetermined position.

On the other hand, the lock device 6 has a rotary knob 12. The rotary knob 12 can rotate, and by rotating, the dead bolt 7 can be retracted. Although a specific structure is not limited, for example, a pinion is provided coaxially with the rotary knob 12 and meshes with a rack formed on a part of the dead bolt 7. Therefore, if the rotary knob 12 is turned, the rack can slide and retreat.

When the power is turned on, the lock is unlocked. When the power is turned off, the coil spring of the solenoid is extended, and the dead bolt 7 protrudes. It is also possible to control so that the bolt 7 projects and locks. When a fire or the like occurs and the electric system fails, it is preferable that the deadbolt 7 of the lock device be retracted and unlocked if safety is considered. However, if it is necessary to keep the lock state at all times, turning off the power supply has the advantage that power consumption is not required.

On the other hand, the rotary knob 12 as a means for manually unlocking the lock is merely one specific example. Therefore, another operation unit such as a lever operation can be used. As described above, the sliding door device with a lock mechanism according to the present invention includes a locking device having a dead bolt that appears and disappears when electricity is turned ON / OFF on the upper rail side, and the protruding dead bolt is fitted on the sliding door side. A receiving member having a mating fitting groove is provided, and the following effects can be obtained.

[0017]

The sliding door device with a locking mechanism according to the present invention has a locking device on the upper rail side, and the dead bolt of the locking device protrudes to fit into the fitting groove of the receiving member provided on the sliding door, thereby sliding the sliding door. Is locked from opening. And since the lock device is electrically controlled, it can be operated not only at the entrance of the room and the office but also remotely from a remote place.

In the present invention, since the lock device is provided on the upper rail side, it is not necessary to provide electric wiring on the sliding door, which is simple, and furthermore, failure due to electric trouble can be prevented. Further, when the lock device does not operate due to an electrical trouble, the lock can be unlocked by operating an operation unit such as a rotary knob. On the other hand, the dead bolt of the lock device has a sensor for detecting the closed state of the sliding door so that the dead bolt projects only when the sliding door is completely closed and fits into the fitting groove.
