[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of rotating a latch shaft by operating a handle provided on a door, and engaging and disengaging a latch connected above and below the latch shaft with a locking hole of a furniture body. about facilities unlocking device of a door in furniture or the like to be or to release the restraint or restrain the door in the closed state.

[0002]

BACKGROUND OF THE INVENTION facilities unlocking device in the door, such as a conventional rocker, locked by Rukoto to engage the latch provided on the upper and lower ends of the door locking hole of the furniture body of the lockers, the door in the closed state and, and by operating the handle provided on the surface of the door,
By rotating the latch shaft , the latches fixed to the upper and lower ends of the latch shaft are disengaged from the locking holes , and the door can be opened.

[0003]

An invention to be Solved] However, in place of the conventional facilities unlocking device as described above, by engaging the latch provided on the upper and lower ends of the door locking hole of the furniture body, the door
To prevent the door from opening, the middle part of the door is in a free state, and in the high locker door,
And Mase wrinkles between part in the door, there is a possibility to be solved a locked state, is not preferable on crime prevention.

[0004] Further , in conventional locking devices such as lockers, etc.
Means to prevent the rotation of the latch shaft, and
And a dead body that locks into the insertion hole in the housing.
Because it is separate from the means for preventing the sliding of the
The configuration was complicated and the operation was troublesome. Further
However, the conventional locking device has a complicated configuration and operation, and
The work is cumbersome and requires considerable power to operate
Was.

[0005] The present invention has been made in view of the above problems the prior art has, to prevent the deflection of the door in the locked state can be maintained reliably locked state, moreover configuration
It is intended to together with a simple and so can operate smoothly at light force, provides facilities unlocking device of a door in furniture.

[0006]

In order to achieve the above object, the present invention provides a furniture body (2) with a vertical hinge.
Door (1) pivotally connected to open and close, and the vertical direction of the door (1)
Escutcheon (4) attached to the middle part of
The door (1) is opened at the handle (3b) located inside the station (4).
A horizontal rod (3c) extending in the end direction is provided.
Escaping the middle part in the horizontal direction with the vertical axis (3a)
Locking piece attached to the end of the horizontal rod (3c).
(3d) Handle with (3), and up and down on the open side of door (1)
It is inserted into the end and the escutcheon (4), forming a square cross section
Furniture body (2) facing up and down with upper and lower ends
It has a latch claw (6a) that can be disengaged from the locking hole (2b) provided in
A latch shaft (5) to which a latch (6)
Immediately after the locking piece (3d) of the handle (3), open the door (1).
A first protruding piece (7a) facing the release side and a second protruding piece (7b) facing rearward.
And includes a handle (3) of the latch shaft (5).
After the transmission tube (7) fixed to the part and the handle (3)
Side, it is long in the left-right direction,
Top Per unit provided with a (9a), the open end of the door (1)
A vertically long hole (9b) is drilled on the opposite side, and the open end of the door (1)
Are provided in the guide hole (1b) provided in the door (1) and the furniture body (2).
Left and right sliding to enter the insertion hole (2c)
Possible dead bolt (9) and attached to escutcheon (4)
On the back side, the key
It has a bar (8b) and projects backward from the key lever (8b).
And engages with the elongated hole (9b) of the dead bolt (9).
A cylinder lock (8) with a pin (8c) protruding
By operating the cylinder lock (8), the dead bolt
Slide (9) to the left and right, and move it to the furniture body (2).
The bolt is inserted into and removed from the insertion hole (2c).
When it is locked by inserting it into the insertion hole (2c),
The stopper portion (9a) of (9) is connected via the second protrusion (7b)
By rotating the transmission cylinder and thus the latch shaft (5),
And the first projecting piece (7a) of the transmission cylinder (7) is engaged with the locking piece (3d).
Lock and rotate the horizontal rod (3c) and the handle (3)
When the deadbolt (9) is retracted,
The stopper (9a) separates from the second protruding piece (7b) and
(3) and the transmission cylinder (7) are allowed to rotate,
The locking piece (3d) at the tip of the horizontal rod (3c) is the first protruding piece (7a).
To rotate the transmission cylinder (7) and thus the latch shaft (5)
Try to unlock .

The distance between the vertical axis (3a) and the handle (3b) is
Distance between the straight shaft (3a) and the locking piece (3d) at the tip of the horizontal rod (3c)
It is better to keep it smaller than the separation.

[0008]

In the closed state where the latch is engaged with the locking hole,
When the locking operation of the cylinder lock is performed, the dead bolt is engaged with the insertion hole of the furniture main body, and the stopper portion prevents the latch from rotating in the release direction.

[0009] at this locked state, the stopper portion of the dead bolt, since the rotation of the latch is prevented,
The release operation of the handle is prevented , and the door is locked in the closed position by the latch and the dead bolt engaging with the upper and lower locking holes and the insertion hole in the middle part of the furniture body, and the door is elongated in the vertical direction. Even in this case, the middle part of the door does not easily bend, and the security is improved.

According to a second aspect of the present invention, the movement of the handle portion is achieved.
The movement of the locking piece at the tip of the horizontal rod is small with respect to
Then, just move the handle lightly and the second
Dead bolt smoothly through the piece and the stopper
You can move it.

[0011]
