More particularly, the present invention relates to a door opening / closing apparatus for a door, which can easily open and close a door by pushing or pulling a handle of a door in a direction in which the door is opened, And an entrance door opening / closing device for a door which can increase the safety of security through a double locking device.

Generally, the door opening / closing apparatus has a rotary knob on both sides of a door, and a latch interlocking with each knob is projected on an end of the door. Accordingly, when the user holds the handle by hand, the latch is pulled to the inside of the door. When the door is pushed or pulled in this state, the door is opened.

However, in the related art, in order to open the door in a closed state, the door must be opened by sequentially performing two operations, that is, first turning the handle in one direction and then pushing or pulling the door. In other words, the door must be opened by pushing or pulling the door while the user holds the door handle by the hand and rotates, thereby making it difficult to open the door.

Particularly, the continuous operation in which the door is pushed or pulled in a state in which the handle of the door is rotated by one hand while being held by the hand is difficult for the child, the elderly, and the disabled to rotate the door handle, When a user holding a goods wants to access, there is an inconvenience that the carrying object should be lowered on the floor, then the door should be opened, and then the object should be carried in or out again.

In addition, when a crowd crowded in a government office, a theater or the like, or when an emergency occurs such as a fire or a flood requiring urgent evacuation, the operation of rotating the door handle is not quick and a safety accident may occur.

Recently, an opening / closing device for opening and closing the door by simply pushing or pulling the handle without rotating the door handle has been proposed. It is difficult to assemble because many parts are used, and the price of the product is high, the opening and closing operation is not smooth, and the accuracy of opening and closing is low.

In addition, the structure for opening and closing the door by pushing or pulling the handle has a problem that the door is locked by only the latch bolt, so that the security is poor and the door is not suitable for the entrance for the outsider.

In addition, even in the case of the door opening / closing apparatus using the conventional rotary knob, the door can be locked only by the dead bolt, thus always having the risk of theft.

Accordingly, there is an urgent need for a door opening / closing apparatus for a door which can not only open and close the door by pushing or pulling the handle, but also prevent the door from being stolen.
