Description

Sliding door apparatus including jamming prevention device {Sliding door apparatus having jamming prevention device}

The present invention relates to a sliding door device including an anti-jamming device.

Tempered glass doors are mainly installed in places where there are many people entering and leaving, such as shopping malls, schools, and government offices, rather than general houses, and the frequency of safety accidents such as fingers getting caught when entering and exiting is very high.

In the prior art, synthetic rubber or the like was attached to the edge of the glass surface, or a fixture to which the synthetic rubber was attached was inserted into the glass surface. However, the guard of this type is easily discolored by direct sunlight over time, and is also weak in terms of strength, so it is easily torn or ripped off.

As a result, it is often seen that only fixtures without synthetic rubber are attached to places where children come and go, such as schools.

In addition, one or two doors are coupled to a door frame with a hinge means such as a hinge to rotate around the hinge means to open and close the entrance. When such a door is opened or closed, there is a problem in that a person's hand or collar is caught between the door frame and the door or between the door and the door, resulting in injury or damage.

It was developed by improving these disadvantages by installing a rubber plate, windbreak paper, or windbreak brush on the part opposite to the doorframe of the door or the part where the door and the door face each other so that the user's hands or collar are not injured or damaged even if they are caught. Prior art to avoid this has been suggested.

However, since the hand-trap prevention device according to the prior art cannot completely prevent injury while the user's hand is caught, and it is to the extent of mitigating the degree of injury, there is a problem in that safety accidents cannot be completely excluded when closed with strong force. .

In this embodiment, three light emitting elements are disposed, and are referred to as a 1-1 light emitting element 311 , a 1-2 light emitting element 312 , and a 1-3 light emitting element 313 .

The 1-1 light emitting device 311, the 1-2 light emitting device 312, and the 1-3 light emitting device 313 are spaced apart from each other in a horizontal direction by a predetermined interval.

The 1-1 light emitting sensor 315 is disposed between the 1-1 light emitting element 311 and the 1-2 light emitting element 312, and the second light emitting sensor 315 is disposed in two. A 1-2 light emitting sensor 316 disposed between the 1-2 light emitting element 312 and the 1-3 light emitting element 313 is included.

In this case, when the 1-2 wavelength or the 1-3 wavelength is blocked while the 1-1 wavelength is maintained, the 1-1 spectral receiving sensor 315 and the 1-2 spectral receiving sensor ( 316) should not receive the second wavelength split.

When the control unit determines that an obstacle such as a user's hand or body is located between the 1-2 slide side frame 114 and the second outer side frame 240, the jamming prevention device 400 is operated to The movement of the first slide door 101 is limited, and the 1-2 slide side frame 114 and the second outer side frame 240 are spaced apart to form a minimum distance (D).
