Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door handle locking device having a U-shaped door handle so that the locking lever can be unlocked by either pushing or pulling the door handle. It is something.

Conventional door handles of this type have been attached to the door in a fixed position; for example, when the door handle is placed in a horizontal position and is moved to a vertical position, the locking device must be replaced.

Additionally, since unlocking the locking lever was done only by pushing in a certain direction (e.g., pushing), if the door lever was accidentally operated forcefully in the opposite direction (e.g., pulling D), the locking device could be damaged. There were other problems.

The present invention has been made with attention to the above-mentioned points, and its purpose is to provide a door whose locking lever can be unlocked by either pushing or pulling the door handle. The handle is on providing a locking device.

Another object of the present invention is to provide a door handle locking device that allows the door handle to be installed in either the vertical or horizontal position without replacing the locking device. It is in.

An embodiment of the present invention will be described below with reference to the drawings.
A is a door handle lock, which is provided at the free end of the door B, and has a deadbolt 1 and a latch bolt 2, and a cylinder lock 3 for operating the deadbolt 1 on the outdoor side, and an operating knob on the indoor side. 4, and substantially U-shaped door handles 5, 5 for operating the launch bolt 2 are provided on the inside and outside.

At both ends of the door handle 5, a mounting bracket 7 for the side door is rotatably attached to a shaft 6, and at the other end, a forked drive arm 8°8' is provided at a slightly different level. It is provided.

A rotating plate 9 is provided inside the lock A, and four engaging protrusions 9a are provided at four equal parts on the outer periphery of the rotating plate.

9 a'#9 b #9 b' is provided,
A return spring 10 is provided on the extension of the engagement protrusion 9a, and a latch bolt operating rotating body 11 is provided on the engagement protrusion 9b.
A drive arm 12 is connected to the drive arm 12 .

That is, the drive arm 12 has its elongated hole 12a to engage the driven pin 11 in the arm 11a of the latch bolt operating rotating body 11.
By appropriately selecting the intersecting angle between the arm 12 and the arm 11a, the latch bolt can be operated when the rotating plate 9 is rotated in either the clockwise direction or the counterclockwise direction in FIG. At this time, the latch bolt 2, which is constantly urged in the protruding direction by the spring 14, is moved from the connecting fitting 15 through the eccentric cam 13a provided on the shaft 13. It is made to retreat via the engaging portion 15a.

Thus, the bifurcated drive arm 8°8' of the door bundle 5 is
As shown in FIG. 4, the drive arm 8 is placed on the top of the protrusion 9a.
Further, the drive arm 8' is located at the lower part of the protrusion 9a', and when the drive arms 8, 8' are engaged with the opposing protrusions 9a, 9a' from opposite directions, and the door bundle 5 is pulled. When the door bundle 5 is pushed in, the driving arm 8 rotates the rotating plate 9 counterclockwise via the protrusion 9a, and when the door bundle 5 is pushed in, the driving arm 8' rotates the rotating plate 9 via the protrusion 9a'. Rotate clockwise.

When the door bundle 5 is provided vertically, the drive arm 8,
8' indicates the protrusions 9b and 9b as shown by the imaginary line in FIG.
It will be located to the side of '.

Since the present invention is constructed as described above, the locking lever can be unlocked by either pulling or pushing the door bundle, and the mounting position of the door bundle can be changed vertically without replacing the locking device. , which has the feature that it can be selected for any horizontal state.

Claims (1)

[Claims] 1 A two-pronged driving arm extending inward is provided at the mounting base of the U-shaped door handle, and a rotating plate for both clockwise and counterclockwise directions is provided inside the locking device. A rotating body for operating a latch bolt that rotates in a fixed direction when the rotating plate is rotated is provided, and the two-pronged drive arm is rotated against two protrusions at opposing positions on the outer periphery of the rotating plate. When the U-shaped door handle is operated in one direction, only one of the forked drive arms acts on one of the two protrusions and rotates in a certain direction. When the moving plate is rotated and the U-shaped door handle is operated in the opposite direction, only the other of the forked drive arms acts on the other of the two protrusions, and the U-shaped door handle is operated in the opposite direction. A door handle locking device characterized by rotating a rotating plate in a direction.
