Abstract

Door locks, one of the most important materials in housing construction, have handles or levers protruding, making it easy for children to hit their heads and injuring themselves. The family is torn by levers when they are in or out, or the protrusions of door locks This door lock is a method in which the user rotates a handle or a lever to convert the rotational motion into a linear motion, thereby pulling the door latch open.
When a user pulls a door lock opening / closing lever installed in a buried state in a state close to a plane on a door in a form in which the door is not protruded, a pull lever is rotated around an axis provided in the opening / closing lever so that a door is opened It is a flush-type door lock.

Description

Door Lock for internal type

The present invention relates to a door lock of a door of a house or a building.

Most door locks have inconveniences such as that the handle or lever is protruded so that a child who is lacking in attention is likely to be hurt by hitting his head and adults are torn by the lever during entrance and exit, It is a gist of the present invention to improve this.

It is an object of the present invention to develop a door lock having a structure in which a lever of a door lock which is inconvenient in use is not protruded and can be opened and closed with a buried structure.

Generally, most door locks are designed to turn the handle or lever of the protruding door lock, convert the rotary motion into linear motion, and pull the bolt on the door to open the door.

The present invention solves the problem of the present invention by a structure in which a lever is pulled by an embedded lever pulled in a direction of opening a door instead of a lever for rotating movement.
To this end, the flush-type door lock according to the present invention is provided with a ratchet holder embedded in a door, a latch provided on the ratchet holder and having a ratchet central axis, a ratchet spring provided inside the ratchet holder to surround the ratchet central axis, A ratchet body having a ratchet traction plate and a ratchet retractor having a predetermined space; An inner lever rotatably installed on an inner lever shaft mounted on a door lock inner frame, a lock lever which is housed in the ratchet lock body and is coupled to the inner lever to rotate the inner lever, A door lock outer frame installed on the outside of the door around the bolt body, an outer door lockably mounted on the outer lever shaft mounted on the door lock outer frame, And an outer latching torsion lever which is housed in the ratchet body and is coupled to the outer lever and rotated by rotation of the outer lever and is arranged crosswise to the inner latching tines lever to move the latching traction plate backward without mutual interference A driving unit; And a lock pin holder formed on a side surface of the lock pin body. The lock pin body is formed on a side surface of the lock pin body. The lock pin body is formed on the inner surface of the lock pin body. And a lock pin locking portion formed at a lower portion of the lock pin and moved downward by the lock pin projection to prevent movement of the latch pull plate, and a lock pin release plate provided inside the inner lever.

The door lock of the present invention can develop the market-dominant product with an innovative appearance that is out of the conventional design of the existing door lock, in addition to the effect of solving all the problems of the conventional door lock mentioned above.

A ratchet body 1e having a ratchet holder 1b and a ratchet spring 1c and having a ratchet plate 1f at the ratchet 1a and a ratchet central axis 1d as shown in Fig. ) To constitute a bolt body.

The inner lever 2a, the outer lever shaft 2h, and the outer lever shaft center hole 2f, which have the inner lever shaft 2b and the inner lever shaft center hole 2c formed on both sides of the ratchet body constructed as described above, An inner latching lever 2d provided with an outer opening / closing lever 2g formed therein and capable of pulling the latching pulling plate 1f and a space formed at the center thereof so as to intersect with the inner latching pulling lever 2d, And the outer latching lever 2e configured to be able to pull the latch pulling plate 1f without being connected to the inner opening and closing lever 2a and the outer opening and closing lever 2g, respectively, to form the buried door lock driving unit of the present invention.

4, when the user pulls the inner opening / closing lever 2a to open the door from the inside, the inner bolt pulling lever 2d rotates about the inner opening / closing lever shaft 2b The latch pulling plate 1f is pulled to pull the bolt 1a together with the ratchet body 1e to open the door.

Similarly, when the door is opened from the outside, when the outer opening / closing lever 2g is pulled, the outer bolt pulling lever 2e rotates around the outer lever shaft 2f and the bolt pulling plate 1f is rotated together with the bolt pulling body 1e Pulling and pulling the bolt (1a) opens the locked door.

At this time, the width of the bolt pulling plate 1f is wide and the length of the inner bolt pulling lever 2d and the length of the outer bolt pulling lever 2e is sufficiently long so that, from the door of 30 mm thickness to the door of 45 mm thickness It becomes usable.

The lock pin body 3e in which the lock pin lock portion 3h, the lock pin releasing portion 3g and the lock pin projection 3f are formed is provided as shown in Fig. 7, because the door lock requires a locking device capable of locking the door from the inside. A lock pin holder 3d is formed in the door inner frame 3a so as to cover the outside of the lock pin body 3e so that the lock pin moves only up and down. And a release plate 2h.

When the lock pin protrusion 3f is pressed in the door lock device thus configured, the lock pin locking portion 3h moves as shown in FIG. 9 and blocks the moving direction of the latch pulling plate 1f. Even if the outer pull lever 2e tries to pull the latch pull plate 1f, the latch pull plate 1f is blocked by the lock pin lock portion 3h and the door is not opened.

However, when the inner opening / closing lever 2a is pulled at this time, the lock pin releasing plate 2h provided on the inner opening / closing lever 2a also rotates together with the inner lever shaft 2b as shown in Fig. 10, The locking pin is unlocked while the lock pin body 3e which has intercepted the latch pulling plate 1f is pulled and the lock pin is released by the inner latch pulling lever 2d and the bolt 1a is pulled together with the latch pulling plate 1f, This pull will open the door to the book.
