In the out and in bushings 3 and 25, lever springs 18 for restoring operation during the angular movement operation of the out and in levers 1 and 23 are elastically installed by the out and spring supporters 12 and 31, respectively. do.

And the locking means for locking the door (D) inside the door (D) and the release means for releasing it from the outside will be described in more detail below.

First, the configuration of the out lever 1 will be described.

As shown in FIG. 2, the out lever 1 is a conventional cylinder set 5 which can be released by the key 4 on the engaging hole 3a of the out lever 1 and the fixed out lever bushing 3. And a cylinder tail rod 6 coupled to the side of the cylinder set 5 is coupled thereto, and the cylinder tail rod 6 is elastic by the locking cam 7 and the cylinder tail rod spring 22. Is installed.

The locking cam 7 has a coupling hole 7a to which the header 17a of the shaft 17 can be fitted, and a catching recess 7b to which the cylinder tail rod 6 can be caught to the side thereof. At the rear end, two locking recesses 7c on which the locking ball 8 can be placed are fitted. In the locking recess 7c, the locking ball 8 is elastically installed forward by a two-stage locking ball spring 21 by the unlocking plate 9, the locking plate 10, and the locking base plate 11, respectively. .

The unlocking plate 9 is formed with a square coupling hole 9a in which a square pipe 16 having a rectangular cross section is fitted in a locking manner to rotate the key 4 or the lever 23 to rotate the shaft 17. When the rotation is rotated by the unlocking plate (9) is rotated by the square pipe (16) coupled to the shaft 17 acts to release the locking ball (8) from the locking recess (7c) door lock (A) To switch to the unlocked state.

And the unlocking plate 9 is coupled to the locking base plate spring pin 35 that can control the rotation angle thereof to be guided in contact with the guide groove (7d) formed in the locking cam (7).

Meanwhile, as shown in FIG. 3, the in lever 23 fixes the cap 26 connected to the piston 28 with the cap spring pin 27 on the inlevers bushing 25 to engage the inlevers bushing 25. Is coupled to the ball (25a), the upper portion of the coupling hole (25a) is formed in the anti-rotation opening (25b) to allow the rocker (28a) that can flow up and down slightly on the piston 28 to enter and exit.

And the coupling hole (28b) of the piston 28 via the spring 32 to the roller 29 is elastically coupled, on the roughly S-shaped guide groove (28c) formed left and right on the piston (28) Guide pins 29a guided to the rollers 29 are coupled to the corresponding surfaces of the rollers 29, and the rollers 29 have shaft coupling holes 29b to which the shafts 17 are fitted.

And the rear side of the roller 29 is formed in a rough ring shape and the locking plate 30 having the locking stone piece 30a formed at the inner edge of the rotation preventing opening 25b and the in-loose bushing 25, respectively, before and after It is coupled in an interference fit to (24).

In the figure, reference numeral 28d shows a guide protrusion formed on the piston, and 25c shows a guide recess formed on an inner edge of the inlevers bushing 25 for guiding the guide protrusion 28d.

An operation of switching to an unlocking state and a locking state of the door lock A of the present invention, which can be configured as described above, will be described in detail below.

The out lever 1 has an out lever bushing 3 and the in lever 23 are prevented from rotating by a polygonal part such as eight angles provided in the in lever bushing 25, and the out lever is turned out by the lever setting bolt 20. If the inlevers (1, 23) are assembled without being separated, and the direction of the out / inlevers (1, 23) does not correspond to the door (D) opening / closing direction, etc., remove the lever setting bolt (20) The direction of the post-out levers 1, 23 can be changed laterally.

The guide projection piece 28d of the piston 28 is guided to the guide recess 25c formed in the inner lever portion of the inlevers bushing 25 so that the piston 28 is pushed toward the out lever 1, and the key 4 is unlocked. The guide protrusion piece 28d of the piston 28 is located in a wide part of the guide recess 25c of the inlevers bushing 25 so that the piston 28 is rotated by about 3 mm, and the locking stone piece of the locking plate 30 The locker 28a of the piston 28 hanging on 30a is released and the roller 29 is switched to the unlocked state.

When the inlevers 23 are operated in the locked state, the locking plate 30 is locked in the hole of the in-rose 24 and cannot be rotated so that the piston 28 locker 28a is released and is in the unlocked state.

The spring 26 between the roller 29 and the piston 28 causes the cap 26 to protrude out of the inlevers 23 connected to it when the piston 28 is unlocked.

At this time, since the roller 29 has the guide pin 29a of the roller 29 fitted into the S-shaped guide groove 28c of the piston 28, the roller 29 determines the rotational operation of the roller 29 when the piston 28 slides. At the same time, the angle of the shaft 17 inserted into the shaft coupling hole 29b in the roller 29 is maintained. Therefore, the direction of the locking cam 7 to which the header 17a side of the shaft 17 is coupled is also determined.

In order to lock the door D from the inside, when the cap 26 of the in lever 23 side is pressed with a finger, the cap 26 moves linearly and moves about 8 mm toward the out lever 1. Then, the locker 28a of the piston 28 connected to the cap 26 and the cap spring pin 27 is elastically engaged via the locking stone piece 30a of the locking plate 30 to lock the locking stone piece 30a. And the guide pin 29a of the roller 29 rotates about 35 ° along the S-shaped guide groove 28c of the piston 28 as the piston 28 moves toward the out lever 1, and at the same time The shaft 17, which was fitted to the shaft coupling hole 29b of the roller 29, rotates at the same time, and rotates the locking cam 7 on the out lever 1 side by about 35 ° so that the locking ball 8 locks. The locking recess 7c and the locking plate 10 of the cam 7 are pushed toward the locking plate 10 and the door lock A is locked.

The locking pipe 8 is positioned between the locking plate 10 and the unlocking plate 9 so that the square pipe 16 coupled to the coupling hole 9a of the locking plate 10 is located on the inlevers 23 side. It is fitted in the square hole of the spring supporter 31, and when the out / in levers 1 and 23 are rotated, the latch of the door lock is operated.

However, when the cap 26 of the piston 28 on the in lever 23 side is pressed, the roller 29 rotates, and the shaft 17 coupled to the roller 29 also rotates, and at the same time the side of the out lever 1 side. The locking cam 7 also rotates.

Then, the locking ball 8 is fitted on the locking plate 10 and the unlocking plate 9, and the locking ball 8 is driven by the expanding force of the locking ball spring 21 to lock the locking cam 7 and the locking plate ( 10) is moved between.

When the locking ball 8 is located between the locking cam 7 and the locking plate 10, even if the out lever 1 is operated, the square pipe 16 does not rotate and the door lock A is locked. Of course, the out lever 1 is idle.

The locking cam 7 and the cylinder set 5 have no problem for the locking cam 7 to rotate because the cylinder tail rod 6 always pushes the cylinder tail rod spring 22 toward the cylinder set 5.

When the key 4 is inserted into the key hole of the cylinder set 5 to open the door D from the outside, the key 4 pushes the cylinder tail rod 6 toward the inlevers 23 by about 2 mm to the locking cam. Engaged in the locking recess 7b of (7), the cylinder set 5 is also rotated at that position to release the locking.

Then, the locking ball 8 is pushed by the elasticity of the locking ball spring 21 toward the locking plate 10 and the unlocking plate 9 between the locking cam 7 and the locking plate 10. At the same time, the roller 29 on the inlevers 23 side also rotates in the unlocking direction, and the piston 28 also rotates about 3 mm to lock the piston 28 locked on the locking stone piece 30a of the locking plate 30. The locker 28a is out of the locked state. Therefore, the roller 29 is switched to the rotatable state to be in the unlocked state.

As described in detail above, in the present invention, in the lever-type tube door lock (A), the door lock (A) is also locked by the push operation of the cap (26) on the inner lever (23) side, which is the inner side of the door (D). It can be switched to a state to maximize the convenience of use.It can be installed by simply changing the direction according to the installation direction of the out / in lever (1,23) and the door (D). Durability can be improved further, and the anticipated effect is the invention with much.
