DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock handle device which is removed from a case after a key handle used for opening and closing the door locks the door to a fixed frame.

[0002]

2. Description of the Related Art Various types of key handle detachable / removable lock handle devices have been already proposed, but the lock function is accurate but the structure is complicated, or the lock is simple but the structure is simple. Many were inferior in function.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a key-handle-removable lock which has an excellent locking function, has a relatively simplified structure, and can be manufactured and assembled easily and at low cost. It is to provide a handle device.

[0004]

The lock handle device according to the present invention will be described below with reference to the reference numerals in the accompanying drawings. The lock handle device is provided with a case 1 fixed to a door 34 and provided with a key hole 16 in the center of the front surface. A spring receiving hole 25 is provided at the center of the front surface, passive projections 20 and 21 are provided at the periphery of the front surface, a pin hole 22 is provided at the periphery of the front portion, and a locking shaft portion 24 is provided at the center of the rear surface. A protruding rotor 2; cutouts 26, 27 which are accommodated in the case 1 so as to be movable in the front-rear direction and engage with the passive projections 20, 21 of the rotor 2 are provided through the peripheral edge in the front-rear direction. Drive pin 28 inserted into the pin hole 22
A cover plate 3 projecting from the center of the rear surface;
And a shaft hole 30 in which the locking shaft portion 24 of the rotor 2 is inserted is inserted through the center portion in the front-rear direction, and a lock pin receiving hole 29 is provided in a peripheral portion of the front surface so as to face the pin hole 22 of the rotor 2.
And a key handle 5 into which the operating portion 33 is inserted into the key hole 16 of the case 1; and a spring 8 inserted into the spring receiving hole 25 of the rotor 2 to urge the cover plate 3 forward. The lock pin 9 is inserted into the lock pin receiving hole 29 of the rotor guide 4, is forwardly urged by the spring 10, and has a front end engaged with the pin hole 22 of the rotor 2.

In order to unlock the door 34 from the fixed frame, the key handle 5 is inserted into the key hole 16 of the case 2 as shown in FIG. 3 is retracted against the bias of the spring 8. Due to the retreat of the cover plate 3, the passive projections 20 and 21 of the rotor 2 relatively project toward the front side of the cover plate 3, and the passive projections 20 and 21 are in the same plane as the operation part 33 of the key handle 5. I come to. The drive pin 28 which has entered the pin hole 22 deeply by the retreat of the cover plate 3 retreats the lock pin 9 against the bias of the spring 10 as shown in FIG. 22 and is immersed in the lock pin receiving hole 29 of the rotor guide 4. Thus, since the rotation constraint of the rotor 2 on the rotor guide 4 is released, the key handle 5
Is rotated in a predetermined direction, and the rotor 2 is rotated to the unlocking position by pushing the side surfaces of the passive projections 20 and 21 with the operation unit 33 as shown in FIG.

The rotor 2 is returned to the locked position by turning the key handle 5 in the reverse direction, and the operating portion 33 of the key handle 5 is
When the lock pin 9 is removed from the key hole 16 of the
The front end of the pin hole 22 of the rotor 2
Engages the rear end. As a result, the rotor 2 is non-rotatably restrained with respect to the rotor guide 4, and the door 34 is
Is locked to the fixed frame by the locking member 11 connected to the locking shaft 24. The passive projections 20 and 21 of the rotor 2 that have relatively moved inside the notches 26 and 27 of the cover plate 3 have the front end surfaces at the same surface position as the front surface of the cover plate 3.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, a click recess 23 is provided in a peripheral edge of a rear surface of a rotor 2 and a pin hole 22 is provided.
And the click recess 23 are arranged on the same circle, and a click pin receiving hole 35 is provided on the peripheral edge of the front surface of the rotor guide 4 so as to face the click recess 23.
5 is inserted with a click pin 15 whose front end is engaged with the click recess 23 by being urged forward by a spring 36. When the rotor 2 rotates in the unlocking direction, the front end surface of the click pin 15 is pressed against the tapered inner surface of the clip recess 23, so that the click pin 15 is retracted against the bias of the spring 36, and the click receiving portion 23 of the rotor 2 is pressed. And is immersed in the click pin receiving hole 35 of the rotor guide 4.

The two passive projections 20 and 21 of the rotor 2
The operation unit 33 of the key handle 5
Reference numeral 33 also protrudes from the side surface of the distal end at an interval of 180 degrees. The two pin holes 22 of the rotor 2 are also provided at intervals of 180 degrees, and are spaced 45 degrees from the passive projections 20 and 21. The two click recesses 23 are also provided at 180-degree intervals, and are set at 90-degree intervals with respect to the pin holes 22. Therefore, the rotor 2 is moved 90 degrees from the locked position.
When rotated, the click pin 15 advances by the bias of the spring 36, and the front end engages the rear end of the pin hole 22 of the rotor 2, while the lock pin 9 advances by the bias of the spring 10. The front end engages with the click recess 23.

The two drive pins 28 of the cover plate 3
Numeral 28 is fixed by caulking the front end to the cover plate 3. The urging spring 8 of the cover plate 3, the urging spring 10 of the lock pin 9, and the urging spring 36 of the click pin 15 are all constituted by compression coil springs. Locking member 1
Reference numeral 1 denotes a plate member, and a locking shaft portion 2 is formed by a square hole 38 at a base end portion.
4 and is connected to the rotor 2 by a bolt 14 screwed into a screw hole 37 of the locking shaft 24. A flat washer 12 and a washer 13 with a locking claw are inserted between the bolt 14 and the locking shaft 24.

The case 1 inserted into the mounting hole 40 of the door 34 from the front side is fastened and fixed to the door 34 by the nut 6 fitted to the outer thread 39. The rotation preventing projection 17 is provided at the front end of the outer peripheral thread portion 39. A C-shaped ring 7 is inserted between the nut 6 and the door 34. Since the rotor projection 4 has the positioning protrusion 31 on the outer peripheral surface inserted into the positioning recess 18 on the inner peripheral surface of the case 1, the rotor guide 4 cannot rotate with respect to the case 1. Screw hole 1 of case 1
The screw 41 is screwed into the screw receiving hole 32 of the rotor guide 4 from 9 to fix the rotor guide 4 to the case 1.

[0011]

As described above, according to the lock handle device of the present invention, the locking shaft portion 24 of the rotor 2 is inserted into the shaft hole 30 of the rotor guide 4 fixed to the case 1 and is advanced by the spring 8. The drive pins 28 of the cover plate 3 housed in the case 2 are inserted into the pin holes 22 of the rotor 2, and the passive projections 20, 21 of the rotor whose side surfaces are pushed by the operating portion 33 of the key handle 5 are attached to the cover plate 3. The lock pin 9 inserted into the lock pin receiving hole 29 of the rotor guide 4 is engaged with the pin hole 22 of the rotor 2 by the forward urging of the spring 10, and the operating portion 33 of the key handle 5 is engaged with the notches 26 and 27. By pushing the cover plate 3 in, the lock pin 9 is inserted into the lock pin receiving hole 29 by the drive pin 28, so that the structure is relatively simplified, and It has the advantage of being easy and cheap to stand, and has a locking function with excellent reliability.
