The present invention relates to a door opening and closing device that can be opened and closed in both directions, and more particularly, to a two-way door opening and closing device that can freely open and close the door to the left or right while disassembling or assembling the door.

In general, as shown in FIGS. 1 and 2, the one-way door has one rotary shaft 4 arranged up and down on one side of the door 2 to move the door 2 to the main shaft 1 with the rotary shaft 4. It is configured to be coupled to, so as to rotate the handle (3) to open and close the door (2) in one direction about the axis of rotation (4), the one-way opening and closing door is configured so that space can be secured in the opening direction There is a problem that can be used only when the installation, and also because the combination of the rotating shaft and the main body is combined with a separate hinge, the number of parts increases, causing a cost increase of the product, there is a difficulty in disassembly, assembly.

Conventionally, various developments have been made so far in view of the above problems, and for example, the bidirectional door opening and closing device is disclosed in the patent application No. 92-19020 filed by the present applicant.

Bi-directional door opening and closing device as described above is composed of a spring support plate for supporting the spring inside the handle and the upper and lower handles that operate up and down when opening and closing the door by opening the left and right rotation bar, the structure is complicated and the number of assembly parts increases The cost of the product was raised, and its appearance was not beautiful, which resulted in the deterioration of the value of the product.

The present invention has been made in consideration of the above circumstances, and its object is to be able to easily disassemble and assemble the door while opening and closing the door to the left and right, in particular, the device for opening and closing the door is installed compactly in front of the door It is to provide a two-way door opening and closing device that can simultaneously perform the left and right opening and closing function of the door and the beautiful aesthetic function.

The present invention for achieving the above object is coupled to the insertion hole formed in the insertion groove facing the upper left, right, lower body and the inside of the door is connected to the rotating shaft rod or inserted into the insertion groove, the rotating shaft rod and the door The rotary link is opened and closed, and the button for operating the rotary link.

Therefore, only the button and the door handle are formed to protrude out of the door.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

3 to 5 show a bidirectional door opening and closing device according to the present invention, the bidirectional door opening and closing device is an insertion opening 42, 421, 422 formed with the insertion groove 44 to the upper and lower left and right of the main body 10 ), The rotary shaft rods 40, 421 and 422 coupled to and separated from the insertion groove 44, the rotary link 46 connected to be interlocked with each other about the central rotary shaft 48, and the rotary link 46 It is composed of a button 32 for advancing and rotating the rotary shaft 418, and a spring 38 connected to the rotary link 46 to advance and retract by pressing the button 32 to give a restoring force to the rotary link 46.

And the guide plate 52 for guiding and supporting the rotary shaft rod 40 is coupled, the rotary shaft rod 40 and the connecting rod 402 is connected by riveting, the handle plate 36 to the front of the door 50 ) Is attached.

In the accompanying drawings, reference numerals 30, 301, and 302 denote handles of a door, 20 denotes a enclosure, and 54 denotes a screw that couples the enclosure 20 and the door 2 to each other.

The operation of the present invention will now be described with reference to the drawings.

First, as shown in FIG. 4, by holding the handle 30 of the door 50 in the direction to open by selecting a direction to open the door 50 while the door 50 is closed to the main body 10. Pressing the button cover 32 with the thumb, the button 32 is advanced as shown in FIG. 5, the rotary link 46 is retracted by the button 32, and the rotary link 46 and the connecting rod 402. Both ends of the rotated shaft 40 is released from the insertion groove 44 of the insertion hole 42, and in that state, the other side of the rotating shaft bar serves as the rotating shaft, and the door 50 is opened.

To open the door on the other side, hold the other hand in hand and press the button cover with your thumb to open the door in the same operation as above. When locking the open door 50, close the door 50 and press the button. When the cover 32 is pressed and released, the rotary link 46 is restored to its original shape by the restoring force of the rotary link 46 and the spring 38 protruded inside the door. Is inserted into the insertion groove 44 of the insertion port 42 and the operation is completed.

And when you want to remove the door 50 from the body 10, holding the left and right handles (301, 302) by hand and pressing the curtain cover (341, 342) at the same time with your thumb, the rotary shaft rods (401, 402) as described above ) Is separated from the insertion groove 44 of the insertion port (421, 422) can be separated from the main body 10, and when assembled, it is good to proceed in the reverse order to combine.

As described above, the present invention is only the button cover and the handle is simply protruded to the outside of the door, the appearance is beautiful and excellent in aesthetic function, easy to assemble and disassemble, can easily open and close the door of the left or right selectively It is an invention that can utilize the installed space usefully.
