At this time, the dead bolt 200 is drawn in and out of the housing 100 through the dead bolt operating hole 112 in the form of a straight reciprocating motion to repeat the lock and release of the door, the latch bolt 300 is The locking and unlocking of the door is repeated while being drawn in and out of the housing 100 through the latch bolt operating hole 114 in the form of a folding and rotating movement.

Here, the dead bolt 200 is a member that performs a safety lock function, the latch bolt 300 is a member that normally performs a conventional door lock function.

In addition, the rear end of the dead bolt 200, for example, the guide groove 210 is formed by a predetermined length (sufficient length required for drawing in and out of the dead bolt) is formed in the housing 100, the guide groove ( 210 is guided while sliding while being fitted to the dead bolt guide (120).

In addition, the dead bolt guide 120 is provided in the inner place of the housing 100, has a protruding form and is integrally formed when the housing 100 is formed or may be provided through various fixing methods such as bolt fastening method. Can be.

In addition, the center of the rear end of the dead bolt 200 is fixed to the bolt (B) on both sides after the operation piece 220 is inserted, the engaging groove 222 is formed at the end of the operation piece 220.

At this time, the locking groove 222 is more preferably formed in the form of a two-stage locking groove having a step 224.

Meanwhile, a cylindrical first pivotal body 230 is rotatably fixed in the housing 100, and an extension piece 232 is protruded on an outer circumferential surface of the first pivotal body 230. A locking protrusion 234 that is caught by the locking groove 222 is formed in the protrusion 232, and a knob rod insertion groove G1 is recessed on a protruding cross section of the first pivot 230.

In addition, the first pivot 230 serves as a kind of rotation shaft, and the torsion spring 236 is fitted on the outer circumferential surface thereof, and one end of the torsion spring 236 is supported by the pressing piece 240. The other end is supported by the boss 130 in a state of being engaged with the first rotating body 230 to provide an elastic return force when the first rotating body 230 rotates.

Here, the pressing piece 240 is disposed to penetrate through a portion of the housing 100, is provided in a state that is elastically supported by the coil spring 242 and slidable, preferably one end of the torsion spring 236 That is, the support end is configured to maintain the state always pushing toward the dead bolt (200).

In addition, a part of the outer circumferential surface of the first rotating body 230 in which the extension piece 232 is formed, the rotating body catching jaw 238 as shown in FIGS. 3 and 4 is integrally formed, and the rotating body catching jaw 238 is engaged with the pressing piece engaging jaw 252 of the bending piece 250 is extended vertically from the pressing piece 240, the pressing piece engaging projection 254 is a part of the bending piece 250 Protruding and configured to slide in the horizontal direction, the elastic return force of the pressing piece 240 as well as the rotational movement of the first rotating body 230 by the left and right sliding of the bending piece 250 is generated.

Therefore, the dead bolt 200 is moved into the housing 100 by the rotation of the operation rod (not shown, the member is rotated by the handle provided in the door lock body) inserted into the operation rod insertion groove G2 to be described later. If the dead bolt 200 is to be smoothly and stably linear movement without shaking along the dead bolt guide 120, at the same time the locking projection 234 was caught in the locking groove 222 of the operating piece 220. ) Rotates the extension piece 232 while the operation piece 220 is moved in the retracting direction, thereby compressing the torsion spring 236 while the first rotating body 230 is rotated to secure rotational return force. In addition, when the force is greater than the elastic force of the coil spring 242, the pressing piece 240 is retracted and the coil spring 242 also operates in a compressed form.

However, the dead bolt 200 is a state in which the locking projection 234 is always hung on the step 224 of the locking groove 222 of the operating piece 220 connected thereto, in particular the locking projection 234 is Since the fixed extension piece 232 is hung in the form of being supported at an angle toward the step 224, the dead bolt 200 cannot be forced in without the release. .

Moreover, a part of the outer circumferential surface of the first rotating body 230 in which the extension piece 232 is formed, the rotating body catching jaw 238 is integrally formed, the rotating body catching jaw 238 of the bending piece 250 Since the dead piece 200 is engaged with the pressing piece catching jaw 252, the dead bolt 200 cannot be opened by external force or by forcibly applying force from the outside unless the engagement is released.

As a result, the dead bolt 200 can faithfully perform the double safety lock function as its own purpose.

On the other hand, as shown in Figures 2 to 5, one end of the first operating guide 260 is caught by the pressing piece engaging projection 254, the first operating guide 260 is connected to the induction shaft 264 It is rotatably fitted, and a part of the first locking projections 266 is formed to protrude.

In addition, one end of the second working guide 262 is rotatably fitted to the derivative rotating shaft 264, and the second working guide 262 is composed of a member separate from the first working guide 260. The first working guide 160 is disposed in a direction opposite to each other, and a part of the second locking protrusion 268 is formed to protrude.

In addition, the derivative rotating shaft 264 is coupled to the elastic member 270, the elastic member 270 has a 'TT' shape, one end is caught by the first engaging projection 266, the other end is It is caught by the second locking projection 268.

In addition, the first operating guide 260 and the second operating guide 262 meets one side, that is, toward the dead bolt 200 toward the direction of the first, second working guide 260, 262 is approximately '⊃ 'Shaped space is formed, and the pressing piece 282 is disposed on this space.

At this time, the pressing piece 282 is integrally fixed to the second rotating body 280, the second rotating body 280 is configured to rotate in a certain angle in accordance with the vertical flow of the vertical fluid 290 In addition, the vertical fluid 290 is installed to be moved by the drive motor (M).

To this end, as shown in Figs. 2 to 6, a rotating flow shaft 292 is formed on one side of the upper and lower fluid 290, the link 294 extending therefrom is eccentrically fixed to the motor rotating plate (C) A shaft pin 296 is installed at a portion of the length of the link 294 so as to be movable in the flow groove 298 formed in the upper and lower fluids 290.

However, in the drawings for convenience of description, only a part of the link 294 eccentrically fixed to the motor rotating plate (C) is shown in a cut form.

Accordingly, when the driving motor M is rotated, the link 294 is eccentric, and the rotational flow shaft 292 connected to the link 294 tries to move in the up and down direction, but this is the up and down fluid 290. Since it is constrained to, the vertical fluid 290 freely flows up and down eventually.

Here, the upper and lower fluids 290 are freely movable in the guide groove (not shown) formed in the housing 100.

At this time, an end of the rotary flow shaft 292 inserted into the upper and lower fluids 290 is fitted with an elastic spring (S1), which is a kind of torsion spring, one end of the elastic spring (S1) to the upper and lower fluids (290) The other end is locked to the head surface of the connecting shaft (L).

One end of the connecting shaft L is connected to the pressing piece 282 integrally formed with the second pivot 280 by penetrating the vertical fluid 290 in the front-rear direction as shown in FIGS. 5 and 6. .

Therefore, the vertical flow of the vertical fluid 290 rotates the second rotary body 280 in the left and right directions within a predetermined radius by the above-described connection relationship.

In addition, an operation protrusion 284 protrudes downward in a portion of the upper and lower fluid bodies 290, and the operation protrusion 284 is caught in the step engaging groove A1 (see FIG. 5), and the step engaging groove A1. ) Is formed in the upper surface of the multi-stage operation piece (A).

One end of the multi-stage operating piece A is rotatably fixed to the housing 100, and the other end is constrained by a spring (not shown) to elastically move up and down within the guide 286.

In addition, the other end of the multi-stage operation piece (A) is designed to be locked or released according to the lower end and the flow position of the slide member 310 connected to the latch bolt (300).

Further, the rear end of the slide member 310 is supported by one end of the coil-shaped elastic spring (S2), the other end of the elastic spring (S2) is supported on the support wall (W), the support wall (W) is a housing It is fixed to the bottom surface of 100.

In addition, an operation rod insertion groove G2 is formed in the cross section of the second pivot 280, and the main operation rod that is rotated and flown by an operation lever (knob) provided in the door lock body is inserted therein.

Accordingly, the second rotating body 280 may be rotated counterclockwise or clockwise by pushing or pulling the indoor and outer levers. If the counterclockwise rotation is described as an example, the second rotating body 280 may be rotated. The pressing piece 282 integrally formed with the fuselage 280 presses the first operating guide 260, and when it is rotated in a clockwise direction, presses the second operating guide 262. The operating guides 260 and 262 are configured to retract the pressing piece catching projection 254 unconditionally at the moment of being pressed.

In addition, when the pressing piece 282 is disposed in the space between the first and second working derivatives 260, that is, the pressing piece 282 does not press either only when the indoor and outer levers are not operated.

In addition, the latch bolt 300 is the rear end of the slide member 310 is caught by the rear end of the multi-stage operating piece (A), and when the operation protrusion 284 is rotated to press a part of the step catching groove A1, the rear end thereof. Pressing along the guide 286 releases the state of engagement with the slide member 310, and at the same time the slide member 310 is pulled by the compression force of the elastic spring (S2) while the inside of the housing 100 in the form of rotation folding The door can be opened because it is pulled in toward.

In this case, the door is incapable of opening the door by specially designing the stepped locking groove A1 to maintain the state where the dead bolt 200 is inserted first before the latch bolt 300 is rotated and folded when the door is opened. It is more preferable to configure so as to prevent in advance.

That is, the actuating protrusion 284 and the pressing piece 282 are integrally fixed to the second rotating body 280 while maintaining the proper angle, and the pressing piece (when the rotation of the second rotating body 280 flows) The shape of the stepped groove A1 is machined so that the actuating projection 284 presses the multi-stage operating piece A after the 282 first strikes any one of the first and second working derivatives 260 and 262 first.

The present invention having such a configuration has the following operational relationship.

First, the mortise according to the present invention may be opened and closed when the second rotating body 280 is directly rotated, and may also be opened and closed when the driving motor M is operated by operating a keypad or an opening / closing button.

For example, when the user pulls or pushes the indoor and outer levers to open the door, the second rotating body 280 is rotated and is located in the space between the first operating derivative 260 and the second operating derivative 262. The pressing piece 282 rotates in either the clockwise or counterclockwise direction.

At this time, in the present invention, since the pressing piece 282 is configured to induce the same operation in any direction, the operation result is not different, which is the same in both the push (push) and pull (Pull) It means to get the operation result.

For example, if it is assumed that the pressing piece 282 is rotated in the clockwise direction as shown in the example of Figure 4, the second operation guide 262 is engaged with the pressurizing it, accordingly, the second operation guide 262 Is rotated counterclockwise about the derivative rotating shaft (264).

However, since the second locking projection 268 of the second working guide 262 is provided with an elastic member 270 that prevents its rotation, the force to rotate is absorbed through the elastic member 270, and Since the elastic member 270 is hung from the first rotating guide 264 of the derivative shaft 264, the opposite end is caught by the first locking projection 266 of the first working guide 260. Will be delivered.

As a result, the force to rotate the second operating guide 262 is converted into a force for rotating the first operating guide 260 by the elastic member 270.

Therefore, the first working guide 260 is rotated clockwise around the derivative rotating shaft 264, thereby pushing the pressing piece engaging projection 254 to retract the bending piece 250.

Of course, the same result when the pressing piece 282 directly presses the first working conductor 260.

As the bending piece 250 moves, the pressing piece 240 integrally formed therewith is also retracted to compress the coil spring 242, and at the same time, the rotating body catching jaw 238 of the first pivot 230 Since the pressing piece engaging jaw 252 that is engaged is also retracted, the engaging relationship between the two is released.

Accordingly, the compressed torsion spring 236 elastically returns to its original position, and in the process, the first rotating body 230 rotates clockwise, and at the same time, integrally with the first rotating body 230. As the extension piece 232 is rotated, the locking protrusion 234 pulls back the operation piece 220 so that the dead bolt 200 is also retracted, and finally, the inside of the housing 100 is released to release the lock state. do.

Along with this, immediately before the dead bolt 200 is completed, the operation protrusion 284 of the second pivot 280 moves inside the step locking groove A1 and presses the multi-stage operation piece A. Accordingly, since the locking end of the slide member 310 of the multi-stage operation piece A is moved downward to release the locking state, the slide member 310 is retracted by the compression force of the elastic spring S2, and the latch bolt connected thereto. As the 300 is rotated and folded, the door 300 is drawn into the housing 100 so that the final opening of the door is made.

On the other hand, the opening process by the rotational drive of the drive motor (M), as described above, the eccentrically fixed link (294) to the motor rotating plate (C) of the drive motor (M) as the eccentric flow lifts the vertical fluid (290) In this case, the connecting shaft L causes the pressing piece 282 to flow, and accordingly, the second rotating body 280 is rotated so that the rotation occurs of the second rotating body 280. The door opening procedure of the next sequence is the same as that of the lever operation described above.

The above description is only a preferred embodiment according to the present invention, of course, can be configured to perform automatic locking and unlocking using an electronic well.
