Description

Sliding door opening and closing device {SLIDING DOOR OPENING AND CLOSING DEVICE}

The present invention relates to a sliding door opening and closing device, and more particularly, to a sliding door opening and closing device that is installed in the slide opening and closing door that can easily open the door by moving the door with a small force with the unlocking when the door is opened. .

In general, the door is a door that can be entered by a person, a window used for the purpose of light or ventilation on the outer wall of the building.

The door has two types of opening and closing types: a door and a door that is opened and closed by rotating the door about a rotating shaft, and a door and a door that is opened and closed by sliding the door along an arbitrary path.

Since these doors are installed in the building, the doors, windows, etc. are opened and closed after unlocking the lock device for the occupant's entrance, room temperature control or ventilation.

The rotating shaft 281 is protruded to both sides of the locking portion 280 to a certain length, is fastened to the locking portion coupling hole 225 of the body portion 220 and the coupling hole 232 of the cover 230 is the locking portion ( 280 is rotated about the axis of rotation 281.

The lock spring 282 is installed between the lock portion 280 in the body portion 220 and the lock portion 280 is moved in the vertical direction due to the movement of the upper and lower lock drives 250 and 260. When opened to provide an elastic force to the lock portion 280 to be in place.

The following describes the operation of the door opening and closing device 200 according to the present invention.

When opening the door 100, when the user grips the handle 210 installed at an arbitrary position of the door 100, the user pushes the handle 210 in the direction to open the door 100, the handle rotating shaft ( The handle 210 is rotated about the 211.

As the handle 210 rotates, the handle gear 212 formed on the handle rotation shaft 211 rotates together, and the drive gear 246 engaged with the handle gear 212 is rotated through the rotation shaft coupling hole 242. Rotate the combined drive unit 240.

When the driving unit 240 rotates, the first driving unit 243, the second driving unit 244, and the cam driving unit 245 formed on the driving unit body 241 also rotate together, and the cam driving unit 245 rotates. Accordingly, the cam part 270 interlocked with the cam driving part 245 moves in the horizontal direction, and the cam part 270 moved protrudes out of the body part 220.

The cam part 270 protruding to the outside of the body part 220 pressurizes the window frame 110 to provide a pressing force so that the door 100 is separated from the window frame 110.

That is, when the handle 210 is pushed in the opening direction of the door 100 to open the door 100, the handle 210 is rotated by a pushing force to the side, and the rotating motion generated by the handle 210 is The door 100 is formed by the cam part 270 converted into linear motion by the knob gear 212 and the drive gear 246, the cam drive part 245, and the cam part 270, and the window 100 is opened by the cam part 270. The pressing force separated from the 110 is generated.

The door 100 is separated from the window frame 110 due to the generated pressing force, and the door 100 is moved by the generated pressing force, so that the user can open the door 100 with little force.

In addition, as the first and second driving units 243 and 244 rotate, the upper and lower locking driving units 250 and 260 interlocked with the first and second driving units 243 and 244, respectively, are upward and downward. The upper and lower locking driving parts 250 and 260 moved to press and open the locking part 280 to release the locking state of the locking part 280 to simply open the door 100. You can do it.

On the other hand, if the handle 210 is released after the door 100 is opened, the cam portion 270 is returned to its original position by the elastic force of the cam portion spring 272, and the locking portion ( 280 and the upper and lower lock driving parts 250 and 260 interlocked with the locking part 280 are returned to their original positions, and the handle 210 is also moved to the original position.

Therefore, by using the handle 210 it is possible to simply open the door 100 with a small force.

As described above, the present invention has been described with reference to a preferred embodiment of the present invention, but those skilled in the art various modifications of the present invention without departing from the spirit and scope of the present invention described in the utility model registration claims below And can be changed.
