Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is only an example and the present invention is not limited thereto.

In describing the present invention, if it is determined that a detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. In addition, the terms described below are terms defined in consideration of functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, the definition should be made based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following examples are merely a means to efficiently explain the technical idea of the present invention to those skilled in the art in the technical field to which the present invention pertains.

Figure 1 is a diagram showing the door lock mortis 10 according to an embodiment of the present invention, and is a diagram in which the operation of the latch bolt 210 is restrained when the door is locked by the deadbolt 312 in the door lock mortis 10, FIG. 2 is an enlarged view of the state between the latch operating member 220 and the latch holding member 230 in FIG. 1.

Referring to Figures 1 and 2, the door lock mortise 10 according to an embodiment of the present invention includes a housing 100 inserted and installed inside the door, a latch bolt 210 located inside the housing 100, and a latch operation. It may include a member 220, an operating unit 240, a deadbolt 312, and a latch member 230. At least a portion of the latch bolt 210 may protrude to the outside of the housing 100 or be formed to be insertable into the interior, and as at least a portion of the latch bolt 210 protrudes to the outside of the housing 100, it is inserted into a groove of the door frame to close the door. It can be maintained in that state. At this time, the latch bolt 210 may be slid to the outside of the housing 100 or rotated around a pre-installed hinge axis to protrude or be inserted.

The latch operating member 220 described above may be formed to rotate around the rotation axis 221, and can control the movement of the latch bolt 210 as it rotates. Preferably, the latch operating member 220 may interfere or not interfere with the movement of the latch bolt 210 as it rotates. Details regarding the interference of the latch operating member 220 with the latch bolt 210 will be described later.

In addition, the above-mentioned operation unit 240 can be rotated by an indoor or outdoor operation means (not shown), and as it is rotated, the latch operation member 220 can be rotated. At this time, the operating means may be a push-pull handle or lever installed on the indoor and outdoor sides of the door, and the operating unit 240 and the operating means may be connected through a shaft. More specifically, a shaft groove 241 may be formed in the center of the operating unit 240, and the operating unit 240 may be rotated by a shaft that rotates according to the user's operation of the operating means.

Furthermore, the latch operating member 220 may include an operating locking protrusion 223 located at an end adjacent to the operating unit 240. As the first latch protrusion 242 and the second latch protrusion 243 formed on the operating unit 240 are rotated, they come into contact with the operation stopper 223 and the actuation stopper 223 can be lifted, and the latch operates. The member 220 may be rotated at a predetermined angle about the rotation axis 221. For example, when the operating unit 240 is rotated counterclockwise with respect to FIG. 1, the first latch protrusion 242 is pushed up, so that the operation stopper 223 is raised and the latch operating member 220 is moved along the rotation axis. It can be rotated counterclockwise around (221). Additionally, as the latch operating member 220 rotates, interference with the latch bolt 210 caused by the latch operating member 220 may be released. Conversely, when the operating unit 240 is rotated clockwise, the operation locking protrusion 223 is raised by the second latch protrusion 243 and the latch operating member 220 is rotated counterclockwise about the rotation axis 221. You can. Additionally, as the latch operating member 220 rotates, interference with the latch bolt 210 caused by the latch operating member 220 may be released.

Meanwhile, the door lock mortis 10 according to an embodiment of the present invention may further include a dead body 310 formed on the inside of the housing 100 to be slideable. At this time, a portion of the dead body 310 may be positioned to protrude outside the housing 100, and the portion of the dead body 310 that protrudes outside may be the dead bolt 312 described above. That is, the deadbolt 312 may be inserted into the inside of the housing 100 or may protrude out of the housing 100 according to the slide movement of the dead body 310.

At this time, the deadbolt 312 protrudes out of the housing 100 and is inserted into the groove of the door frame to lock the door, and is inserted into the housing 100 and moves away from the groove of the door frame to lock the door. It can be unlocked. Additionally, the dead body 310 may be connected to a driving unit (not shown) such as a motor through at least one gear, and may be slid and moved by external user authentication. Additionally, the dead body 310 can be moved by rotating the operation unit 240 for an anti-panic function.

Meanwhile, the latch member 230 described above can control the operation of the latch operating member 220 according to the protrusion or insertion of the deadbolt 312. Preferably, the latch member 230 may be formed to limit contact or release the movement of the latch operating member 220 according to the protrusion or insertion of the deadbolt 312. Specifically, the latch member 230 may be formed to contact or be spaced apart from the latch operating member 220 by moving up and down, left and right, or forward and backward, and when the door is locked by the deadbolt 312, the latch operating member ( 220) rotational motion can be limited by contact.

At this time, due to the contact restriction of the latch holding member 230, the latch operating member 220 may be positioned in a state that interferes with the movement of the latch bolt 210, and the operation of the external operating means and the latch bolt 210 may be operated. Movement may be restricted. That is, when the door is locked by the deadbolt 312, the latchbolt 210 is unlocked, thereby preventing the door jamming problem that may occur when the deadbolt 312 is caught in the groove of the door gap. The movement of the deadbolt 312 and the resulting movement structure of the latch member 230 will be described later in the description of FIGS. 2 to 4.

In addition, the door lock mortis 10 according to an embodiment of the present invention may further include a latch cover 250 that elastically supports the latch bolt 210 inside the housing 100. An elastic body 251 formed of a spring or the like may be disposed between the latch bolt 210 and the latch cover 250, and the latch bolt 210 is supported on the latch cover 250 through the elastic body 251 from the rear. It may protrude out of the furnace housing 100.

That is, the elastic body 251 may be compressed due to interference between the latch bolt 210 and the door frame outside the housing 100, and the latch bolt 210 may be inserted into the housing 100. Conversely, when the interference between the latch bolt 210 and the door frame, etc. is released, the latch bolt 210 may protrude out of the housing 100 due to the restoring force of the elastic body 251.

Meanwhile, the latch cover 250 may be formed to surround the rear of the latch bolt 210 and may be formed in a 'ㄷ' shape open toward the latch bolt 210. Additionally, the elastic body 251 may be supported by the latch bolt 210 at one end and the latch cover 250 at the other end. At this time, the rotation limiting part (231a in FIG. 2) of the locking pin 231 may be inserted between the rear surface of the latch cover 250 on the opposite side of the latch bolt 210 and the rotation locking part 222, which will be described later.

The latch member 230 described above may move downward as the deadbolt 312 is inserted into the housing 100, and may move upward as the deadbolt 312 protrudes outward from the housing 100. Specifically, the latch member 230 includes a locking pin 231 extending up and down, an elastic member 232 that applies elastic force to the locking pin from the lower side of the locking pin 231 toward the deadbolt, a locking pin 231, and an elastic member. It may include a pin housing 233 that accommodates (232). The locking pin 231 described above may be formed in a stick or bar shape.

Additionally, the upper part of the locking pin 231 may be in contact with the lower surface of the dead body 310. As the dead body 310 moves, the height of the lower surface 311 of the dead body 310 changes. As the locking pin 231 is pushed up toward the dead body 310 by the elastic member 232, the locking pin ( 231) may move up and down in response to a change in height of the lower surface 311 of the dead body 310. At this time, guide grooves (not shown) for guiding the locking pin 231 may be formed in the left and right directions on the lower surface 311 of the dead body 310. The guide groove may be used to prevent the locking pin 231 from being separated from the lower surface 311 of the dead body 310 while the dead body 310 is moving. Here, it is exemplified that the shape of the elastic member 232 is a coil spring and is located on the lower side of the locking pin 231, but the position and shape of the elastic member can play the role of the latch member 230 as described above. If so, it can be modified in various ways. According to one embodiment of the present invention, the latch member 230 includes the elastic member 232 so that even when the user arbitrarily manipulates the handle, the locking pin 231 of the latch member 230 is rotated and locked ( The locking pin 231 can be pulled out of the rotation locking portion 222 by elasticity without being caught in the locking pin 222).

More specifically, the lower surface 311 of the dead body 310 may be formed to protrude toward the latch bolt 210 from one side in the protrusion direction of the dead bolt 312 toward the other side in the insertion direction. At this time, the portion protruding toward the latch bolt 210 on the lower surface 311 of the dead body 310 may be referred to as a protrusion 311a. Through this, when the dead body 310 is horizontally moved inward and outward of the housing 100, the locking pin 231 moves upward or downward as the locking pin 231 moves in response to the height of the lower surface 311. You can.

Furthermore, when the deadbolt 312 is positioned to protrude to the outside of the housing 100, the locking pin 231 can be positioned in a downwardly moved state, and when the deadbolt 312 is positioned to be inserted inside the housing 100. The locking pin 231 may be positioned in an upwardly moved state.

Figure 2 shows that when the deadbolt 312 is positioned protruding outward from the housing 100 (door locked state of the deadbolt 312), the locking pin 231 is connected to the rotation locking portion 222 of the latch operating member 220. Indicates the status of insertion. When the deadbolt 312 protrudes to the outside of the housing 100 and the door is locked, the protrusion 311a of the lower surface 311 of the dead body 310 may be located on the locking pin 231. Then, the locking pin 231 can be positioned in a downwardly moved state by being pressed by the protrusion 311a. At this time, the rotation limiting portion 231a of the locking pin 231 may be inserted into and contacted with the rotation locking portion 222, and the rotational movement of the latch operating member 220 may be restricted.

In addition, the restraining means 224 formed on one side of the latch operating member 220 may be positioned inserted into the groove formed in the latch bolt 210, and may be used when the user operates the operating means and moves the latch bolt 210 or Rotational motion may be constrained and limited. That is, when the door is locked by the deadbolt 312, the user's manipulation of the operating means and the operation of the latch bolt 210 may be restricted.

In this embodiment, the locking pin 231 moves up and down depending on the height of the lower surface 311 of the dead body 310 and is inserted into the rotation locking portion 222, but the locking pin 231 is not limited to this. If elasticity is provided to the latch member 230 by the elastic member 232, the upward and downward movement method of the locking pin 231 can be modified in various ways. For example, a curved groove is formed on the side of the dead body 310 to have different heights, and one side of the locking pin 231 is connected to the groove, so that as the dead body 310 moves, the locking pin connected to the groove It is also possible for (231) to move up and down.

Figure 3 is a diagram showing the door unlocking state of the deadbolt 312 in the door lock mortis 10 according to an embodiment of the present invention, and Figure 4 shows the latch operating member 220 and the latch holding member 230 in Figure 3. ) This is an enlarged drawing of the state of the liver.

.

Referring to FIGS. 3 and 4 , a concave portion 311b may be formed in the lower surface 311 of the dead body 310 in addition to the protruding portion 311a. When the deadbolt 312 is inserted into the housing 100 and the door is unlocked, the concave portion 311b of the lower surface 311 of the dead body 310 may be located above the locking pin 231. . Then, the locking pin 231 can be lifted by the elastic member 232 and positioned in an upwardly moved state. At this time, the rotation limiting portion 231a of the locking pin 231 may be pulled out of the rotation locking portion 222, and the rotational movement restriction of the latch operating member 220 may be released.

Then, the restraining means 224 on one side of the latch operating member 220 can be positioned out of the groove formed in the latch bolt 210, and the user's operation of the operating means and the movement or rotation of the latch bolt 210 Restrictions on movement can be lifted. That is, when the door is unlocked by the deadbolt 312, restrictions on the user's operation of the operating means and the operation of the latch bolt 210 may also be released.
