The horizontal rotating gear 131 is a configuration for converting the linear displacement according to the movement of the handle 120 to the rotational displacement, consisting of gears with teeth formed on the outer surface of the truncated conical shape, displacement by a straight line Is composed of any one of a bevel gear, a worm gear, a rack / pinion gear or a cam for converting the rotational displacement into a rotational displacement.

The key box rotation shaft 132 is a rod-shaped member, one side is coupled to the horizontal rotation gear 131, the other side is inserted into the key box 200, the rotational force by the horizontal rotation gear 131 is the key box Connected to be transmitted to the 200, the latch bolt (not shown) installed in the key box 200 is opened as the key box rotation shaft 132 rotates.

The vertical rotating part 140 is configured to be orthogonal to the horizontal rotating part 130, and converts the linear displacement according to the movement of the handle 120 into the rotating displacement so that the horizontal rotating part 130 is centered on the key box rotation axis 132. Rotating, and comprises a vertical rotary gear 141, a vertical rotary body 142, a drive shaft 143.

The vertical rotation gear 141 is configured to convert the linear displacement according to the movement of the handle 120 to the rotational displacement, and consists of a gear having teeth formed on the outer surface of the truncated truncated cone shape in the center, It consists of any one of a bevel gear, a worm gear, a rack / pinion gear or a cam for converting the displacement by rotation into a rotational displacement, preferably a bevel gear.

The vertical rotating body 142 is a rectangular member installed below the vertical rotating gear 141.

The drive shaft 143 is installed at one end of the vertical rotating body 142, protrudes a predetermined length from the vertical rotating body 142, the driving shaft 143 protrudes to the upper and lower portions of the vertical rotating body 142. Is installed.

The support frame 150 is an 'L' shaped member that supports the vertical rotation part 140 to rotate about the vertical rotation part rotation axis 153, and is fixed to the body part 110 through the bolt 153. A keybox rotation shaft through hole 151 through which the keybox rotation shaft 132 penetrates is formed at one side thereof, and the vertical rotation unit rotation shaft is rotatably supported by the vertical rotation unit 140 in a direction perpendicular to the keybox rotation shaft through hole 151. The vertical rotation part rotating shaft through hole 152 through which 153 penetrates is drilled.

In addition, the support frame 150 is installed in the vertical rotating shaft through-hole 152 to support the vertical rotating part 140 to rotate, and the vertical rotating part rotating shaft 153, the vertical rotating part rotating shaft 153 is installed in the vertical The rotating part 140 is configured to include a spring 154 to provide an elastic force to maintain a predetermined position.

That is, the spring 154 provides an elastic force to be restored to its original position when the vertical rotating part 140 rotates about the vertical rotating part rotating shaft 153.

The connecting frame 160 forms a hollow therein, and is a rectangular or cylindrical member whose bottom is cut open to open, one side of the handle second hinge portion 122 at a position spaced apart from the handle 120 by a predetermined distance. When the handle 120 is pulled to the front side of the body portion 110, the vertical rotating portion 140 is pressed to rotate about the vertical rotating shaft 153, the guide portion 161, the connection The frame includes a first through hole 162 and a connecting frame second through hole 163.

The guide part 161 is a guide groove in which a portion of the bottom surface of the main body of the connection frame 160 is cut along the length direction, so that the handle 120 is not pulled so as not to collide with the support frame 150 when the connection frame 160 is moved. .

The connecting frame first through hole 162 is drilled on both sides of the connecting frame 160 to be coupled through the handle second hinge portion 122 and the link portion 123.

The connection frame second through hole 162 is drilled in the lower portion of the connection frame 160 and rotatably coupled to the drive shaft 143 of the vertical rotation part 140.

The selection lever 170 is a member in which the rod-shaped frame is bent into a 'c' shape, and is installed in the connection frame 160 and moves together when the connection frame 160 moves according to the linear movement of the handle 120. The end of the selection lever 170 is in contact with the driving shaft 143 protruding upward of the vertical rotation part 140 to press the vertical rotation part 140 to rotate in either the forward direction or the reverse direction.

The following describes the operation of the pull door lock device according to the present invention.

When the handle 120 is pulled to open the door, the handle 120 moves in the horizontal direction, but the handle first hinge portion 121 is coupled through the body hinge portion 111 and the body rotation shaft 112 to handle the handle. The distal end portion of the 120 is rotated about the body rotation axis 112.

As the handle 120 rotates, the connection frame 160 coupled with the handle second hinge portion 122 moves together with the handle 120, and in a state spaced apart from the handle 120 by a predetermined distance. The coupled connection frame 160 is horizontally moved in the direction in which the handle 120 is pulled due to the handle second hinge portion 122 and the link portion 123.

When the connecting frame 160 is moved horizontally, the end of the vertical rotating body 142 connected through the drive shaft 143 is moved along the connecting frame 160, but the support frame through the vertical rotating shaft 153 Due to the vertical rotation gear 141 supported by 150, the vertical rotation gear 141 does not move, but only the end of the vertical rotation body 142 moves along the connection frame 160, resulting in the vertical movement. The rotary gear 141 is rotated.

In addition, the selection lever 170 presses the drive shaft 143 protruding to the upper portion of the vertical rotating body 142 when the connecting frame 160 is moved so that the vertical rotating gear 141 can be easily rotated.

When the vertical rotary gear 141 rotates in the forward or reverse direction, the horizontal rotary gear 131 is orthogonally engaged and rotates, and the keybox rotary shaft 132 coupled with the horizontal rotary gear 131 rotates. The latch bolt (not shown) of the key box 200 is unlocked.

When the pull of the handle 120 by the user disappears, the elastic force of the spring 154 acts so that the vertical rotation part 140 is returned to its original position, and thus the handle 120 is also returned to its original position.

On the other hand, the pull-type door lock device 100 according to the present invention can be installed and used according to the left opening or right opening door by changing only the installation position of the drive shaft 143 and the installation position of the selection lever 170 without changing the structure. have.

That is, when the driving shaft 143 is installed at one end of the vertical rotating part body 142, and the installation position of the selection lever 170 is adjusted as shown in FIG. 6 to press the driving shaft 143, the handle 120. As the vertical rotation gear 141 is rotated in the reverse direction.

However, when the driving shaft 143 is installed at the other end of the vertical rotating body 142 and the installation position of the selection lever 170 is adjusted as shown by the dotted line in FIG. 6 to press the driving shaft 143, the handle 120 is disposed. As the vertical rotation gear 141 is rotated in the forward direction, it can be installed and used as a left-handed door lock or rainwater door lock regardless of the opening direction of the door.

Therefore, if you pull the handle lever in the direction of opening the door, the door lock device is unlocked and the door can be opened and closed in one operation. Can be installed.
