Description

Improved door locks.

The present invention relates to an improved door lock that makes it easy to open and close the door. Especially, when opening the door (to enter the room), the door lock can be easily opened by simply pushing the door lock. It's very easy to open and go in, and when you want to get out of the door, just pull the door lock.

As is well known, most door locks installed in the front door or door are configured to be pushed or pulled after most of them are held by hands and turned to the left or right. This is very inconvenient for young children to operate, and in the state of holding the goods in both hands, one of the hands of the hand to be put on the floor after opening the very uncomfortable discomfort had to follow.

Therefore, this paper has been devised to solve the above-mentioned general problems. In particular, the door lock can be improved by opening the door by simply pushing or pulling the door lock. To make this very easy, the purpose is to.

1 is a sectional view of the present invention.

2 is a cross-sectional view taken along the line AA ′ of FIG. 1.

3 is an enlarged perspective view of main parts of the present invention;

* Explanation of the main symbols in the drawings.

(1) door (2) (2 ') handle

(3) working rod (4) rack gear

(5) (5 ') pinion (6) axis of rotation

(7) Casing (8) Locking Pin

(9) Rack Gear Rod (10) (15) Compression Spring

(11) Locking piece (12) Locking pin

(13) Clearance hole (14) Rod

Install the operating rod (3) between the two handles (2) (2 ') protruding on the front and rear surfaces of the door (1).

One side of the central portion of the operating rod (3) is " "Into the rack to form rack gears (4) on the surface,

The rotary shaft (6) formed with the pinion (5) to be engaged with the rack gear (4) is installed and connected to the casing (7),

Another pinion 5 'is formed below the pinion 5 of the rotation shaft 6,

Put the rack gear rod (9) connected to the lock pin (8) wave here,

The compression spring 10 and the engaging piece 11 are installed on one side of the operating rod 3 to limit the working distance of the operating rod 3, and at the same time, the compression spring 10 always rests in place and lock pins. (12) by forming a clearance hole (3) inside the upper rod 14 of the rack gear rod (9) is connected to the locking pin (8) with the compression spring (15) and constitutes a door lock.

Reference numeral 16 is the door frame, 17 is the lock pin insertion groove, 18 is the lock pin guide, 19 is the anti-rotation recess, 19 'is the anti-rotation protrusion.

In this way, this proposal can be easily opened by simply pushing the handle (2) of the door lock (20) when entering the room with the door (1) installed (if the door is configured to open inward). Handle (2) (2 ') and the operating rod (3) is configured to operate integrally, and the rack gear (4) is formed in the center of the automatic rod (3), the rack gear (4) and the locking pin ( 8) is operated by the pylon (5) to engage the lock pin (8) by the feed distance of the operating rod (3) [another rack gear on the same axis as the rack gear (5), that is, the rotating shaft (6) 5 ') is formed so that the rack gear 5' actuates the rack gear rod 9 connected to the locking pin 8], so that the door 1 is opened and the door is opened. When the pressure applied to the handle (2) is released, the operating rod (3) automatically returns to its original position and at the same time, the locking pin (8) also protrudes again.

Subsequently, when the door is pushed and closed, the inclined surface of the locking pin 8 and the clearance hole 13 and the compression spring 11 are closed while only the locking pin 8 is raised, thereby closing the door 1 smoothly.

And when you open the door from the room to open the door by simply pulling the handle (2 ') can be opened very easily.

As described above, this proposal is very simple and easy to open the door by simply pushing or pulling the door lock, so children can easily open and close the door even when holding the object in both hands. It is a very useful design that can be opened.
