As shown in FIG. 2, the pivot assembly of the present invention is largely composed of the first pivot member 210, the second pivot member 220, and the third pivot member 230, and coupled to the pivot hole of the mortise body 100. It may be installed in the groove (H1).

The above configuration will be described in more detail with reference to FIGS. 3 and 4 as follows.

The first pivot member 210 has a shaft coupling groove (D1) is formed in the center. The shaft coupling groove D1 is a coupling groove for inserting a handle shaft and may have various shapes according to the cross-sectional shape of the shaft. In addition, the first rotating member 210 may be formed with a stopper 214 for limiting the rotation angle. Another stopper 212 may be formed to perform a function of limiting a rotation direction of the first rotation member 210. In particular, the first pivot member 210 may be provided with a coupling protrusion 213 for engaging with the second pivot member 220. In addition, the operation piece 211 for operating the panic lever 150 is formed.

The second rotation member 220 is formed with a shaft coupling groove D2 having the same size as the shaft coupling groove D1 of the first rotation member 210, and an operation piece 222 for driving the edge bolt 130. Is formed. In addition, the mounting groove 223 is formed so that the engaging projection 213 of the first pivot member 210 is seated. And a stopper 227 for limiting the direction of rotation is provided. And a lever connecting piece 225 for driving another panic lever (not shown) is formed.

The third pivot member 230 is rotatably installed between the first pivot member 210 and the second pivot member 220. In addition, like the above-described rotating members, a stopper 232 for limiting the rotation direction is formed, and another stopper 234 for limiting the turning radius is formed. It also includes an operating piece 231 formed in the same manner as the operating piece 222 of the second rotating member 220. In particular, the third pivot member 230 has a shaft coupling groove D3 having a diameter smaller than that of the shaft coupling grooves D1 and D2 of the first and second pivot members 210 and 220. Accordingly, the third pivot member 230 may operate independently of the first and second pivot members 210 and 220.

It describes the operating state of the assembly of the present invention having the configuration as described above. The dead bolt 110 is driven by the rotation of the dead bolt driving lever 120. On the other hand, the edge bolt 130 is driven by the edge bolt drive lever 140. One end of the edge bolt driving lever 140 is installed to be in contact with the operating pieces (222, 231) of the second, third rotating member. Accordingly, the dead bolt driving lever 120 is operated by the rotation of the second rotating member 220 or the third rotating member 230.

Meanwhile, the first rotating member 210 and the second rotating member 220 are rotated at the same time as they are installed to be engaged with each other. The panic lever 150 is installed to draw in the dead bolt 110 in the state where the dead bolt 110 is drawn out. Accordingly, when the panic lever operating piece 211 of the first pivot member 210 is rotated, the panned lever 150 is pushed to one side to draw the drawn dead bolt 110 into the mortise body 100. .

In addition, the third rotating member 230 may be rotated alone between the first and second rotating members 210 and 220. Accordingly, the edge bolt 130 may be driven alone by rotating the third pivoting member 230.

Hereinafter, the installation and operating state of the door lock having the rotational opening assembly of the present invention will be described. Figure 5 is an installation state diagram showing a door lock having a turning mechanism assembly according to an embodiment of the present invention.

As shown in FIG. 5, the door lock according to the present invention includes an inner handle 300, a mortise body 100, and an outer handle 360.

The inner handle 300 is composed of the handle body 310, the shaft shaft 350, and the elastic member 320. The mortise body 100 is installed inside the door 500. In addition, the inner main body 400 and the outer main body 450 are provided on both sides of the door 500.

The shaft shaft 350 of the inner handle 300 is inserted into the handle body 310. In this case, the elastic member 320 (eg, a spring) is inserted into the handle body 310. Accordingly, one end of the shaft shaft 350 is installed to contact the elastic member 320 and is elastically supported by the elastic member 320. The other end of the shaft shaft 350 is inserted into the shaft coupling groove D1 (FIG. 3) formed in the first pivot member 210 of the pivot hole assembly. In addition, the end of the shaft shaft 350 is formed with a slit groove 330 by a predetermined length, the fixing body 340 is installed in the handle body 310 to be located in the slit groove 330. Here, the slit groove 330 formed in the shaft shaft 350 may adjust the length of the shaft shaft 350 when installed. In particular, the length of the shaft shaft 350 can be adjusted to correspond to the thickness of the door. In addition, the shaft shafts 350 and 365 elastically supported by the elastic member 320 may maintain a close contact with the pivoting hole assembly.

The outer handle 360 also has the same configuration as the inner handle 300, it is installed on the outside of the door 500. In particular, shaft shaft 365 of outer handle 360 has a smaller diameter than shaft shaft 350 of inner handle 300. Accordingly, it is installed to be inserted into the groove (D3) of the third rotation member 230. At this time, each shaft shaft (365, 350) of the outer handle 360 and the inner handle 300 is in close contact with the first rotating member 210 and the third rotating member 230 through the elastic member 320 installed therein, respectively. Can be installed to maintain state.

The door lock according to the present invention configured as described above, when the user rotates the inner handle 300, the first rotating member 210 is rotated, the second rotating member 220 engaged with the first rotating member 210 also rotates together. do. At this time, when the dead bolt 110 is drawn out (ie, locked), the operation piece 211 of the first pivot member 210 pushes the panic lever 150 on one side. Accordingly, the panic lever 150 connected to the end of the dead bolt 110 is rotated to form a state in which the dead bolt 110 is drawn into the mortise body 100 (that is, the unlocked state). At this time, as the driving piece 222 of the second rotating member 220 drives the edge bolt driving lever 140, the edge bolt 130 is also drawn in together.

Such an operation can cause the door to be released quickly, especially if the user wants to go out immediately due to a fire or emergency in the room. That is, even when the user rotates the handle, the dead bolt 110 and the edge bolt 130 may be released at the same time.

On the other hand, the shaft shaft 365 of the outer handle 360 is installed to be inserted into the groove of the third rotating member 230. Accordingly, when the outer handle 360 is rotated, the third rotating member 230 is rotated, and the operation piece 231 of the third rotating member 230 drives the edge bolt driving lever 140 alone. That is, even when the outer handle 360 is rotated, since the first and second pivot members 210 and 220 do not operate, they are not interlocked with the dead bolt 110.

Accordingly, the user rotates the dead bolt driving lever 120 by the key hole or the password input provided in the outer body 450 to achieve a state where the dead bolt 110 is retracted. When the user rotates the outer handle 360, the edge bolt 130 may be opened to open the door 500. In addition, since the first and second pivot members 210 and 220 are formed with shaft coupling grooves D1 and D2 having the same diameter, it is, of course, easy to change the installation to the left hand or the superior.

Although the present invention has been illustrated and described with respect to specific embodiments, the present invention is not limited to the above-described embodiments, and those skilled in the art to which the present invention pertains may find the present invention described in the following claims. Various changes can be made without departing from the spirit of the technical idea of the invention.
