Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to doors of various facilities such as houses and companies, and locks used for doors.

[0002]

2. Description of the Related Art Generally, a lock has a dimension (backset amount) from the front (face plate) of the door to which the lock is attached to the position of the key hole and the hub hole, for example, in the JIS standard, it is 3
It is determined to be 8 mm, 51 mm, 60 mm, 64 mm, and 70 mm, and they are fixed in that size. In addition to this, there are a lot of other things with various sizes, and the size of those things from the front (face plate) to the position of the key hole and the hub hole is predetermined, and they are changed depending on the door to be installed. It is impossible.

[0003]

Therefore, in the above-mentioned conventional lock, it is necessary to prepare the lock according to the standard or various sizes depending on the position of the keyhole or thumb turn attached to the door. In addition, since the door gripping tool and the keyhole have the same backset dimensions, the locks with the dead bolts and the latch bolts provided separately should also have the same position for the door gripping tools. I had to prepare. This was extremely wasteful both in terms of the national economy and inventory management.

SUMMARY OF THE INVENTION An object of the present invention is to provide a lock, which has been made in view of the above-mentioned drawbacks of the prior art, and which can handle various sizes of keyholes and thumb turn positions with a single lock.

[0005]

A lock according to the present invention comprises a dead hub driven by a key or a thumb turn, a sliding member driven up and down by the dead hub, and a driven member driven by the sliding member. In a lock having a hub and a dead bolt that is projectably engaged by the driven hub, the dead hub is provided with a support portion that movably and rotatably supports the dead hub in the cutout hole of the lock body. There is. Also, a dead hub driven by a key or thumb turn, a sliding member driven up and down by the dead hub, a driven hub driven by the sliding member, and a projecting engagement with the driven hub. A lock having a dead bolt is provided with a dead hub holder that supports the dead hub so as to be movable and rotatable in the notch hole of the lock body.

[0006]

As described above, according to the lock according to the present invention, it is possible to cope with differently sized keyholes and thumb turn positions with one lock.

[0007]

An embodiment of the present invention will be described below with reference to the accompanying drawings. The lock 10 includes a dead hub 11 driven by a key or thumb turn, a sliding member 12 vertically driven by the dead hub 11, a driven hub 13 driven by the sliding member 12, and a driven hub 13. The dead hub 1 is provided with a dead bolt 14 engaged so as to project freely.
1 is provided with a support portion 11a which is movably and rotatably supported in the notch hole 16 of the lock body. Dead hub 11
4 to 7, the supporting portion 11a and the sliding member 1 are
It is provided with an operating arm 11b for moving up and down 2 and a biasing arm 11c having a pin 11d with which one end of a spring 18 is locked.
The dead hub 11 is rotatably supported by the dead hub holder 17 by the supporting portion 11a, and the spring 18 urges the urging arm 11c so as not to stop in the middle of the elongated hole 17a.

The dead hub holder 17 is shown in FIGS.
As shown in FIG. 7, a hole 25 into which the dead hub 11 is inserted, a rectangular long hole 17a, claws 17b, 17b and 17c, 17c and an end of the spring 18 which are provided upright in a direction opposite to the surface into which the dead hub 11 is inserted. Has a pin 17d that is locked. The dead hub 11, which is rotatably supported by the dead hub holder 17 in a semi-rotatable manner, is guided by the guide rails 24 provided on the lock body 15 by the claws 17c and 17c, and moves left and right in the lock body. Therefore, the dead hub holder 17 moves only in the lateral direction without rotating in the lock body 15. Further, the dead hub 11 and the dead hub holder 17 are fitted together as shown in FIG. 7, and the pin 11d provided upright on the biasing arm 11c rotates in the elongated hole 17a by the biasing force of the spring 18, A click feeling is given to the rotation operation of the dead hub 11.

The sliding member 12 has a substantially rectangular notch 12a at the center and an engaging portion 19 for engaging with the driven hub 13. Then, the notch hole 16 of the lock body and the notch 12a of the sliding member 12 move within a range where they substantially overlap. The dead bolt 14 has an elongated hole 20 in the center and is guided by a pin 21 provided upright on the main body to move left and right. An engaging recess 14a that engages with the arm 22 of the driven hub 13 is formed at the base end portion. The driven hub 13 is shown in FIG.
As shown in FIG. 10, it has two arms 22 and 23 and pins 22a and 23a, respectively. The pin 23 a engages with the engaging portion 19 of the sliding member 12.

The operation of the lock constructed as above will be described. First, when locking, the dead hub 11 is rotated in the direction of arrow A in FIG. 2 by a key or thumb turn (not shown). Then, the operating arm 11b of the dead hub 11 comes into contact with the lower end of the notch 12a of the sliding member 12 and pushes it downward. When the sliding member 12 descends, the driven hub 13 rotates counterclockwise, causing the dead bolt 14 to project from the lock body. Here, the dead hub 11 stops by the action of the spring 18 at the position where the sliding member 12 is completely lowered or at the raised position, and it is possible to obtain a click feeling without stopping in the middle.

In the case of unlocking, contrary to the above procedure,
Turn the key (not shown) or thumb turn to the right. Dead hub 1
When 1 is turned to the right, the operating arm 11b abuts on the upper end of the notch 12a and raises the sliding member 12. When the sliding member 12 rises, the dead bolt 14 retracts into the lock body via the operation of the driven hub 13. Further, in the lock of the present invention, the dead hub 11 and the dead hub holder 17 can move along the guide rail 24 within the range of the cutout hole 16. If it is within the range of the notch hole 16, the sliding member 12
Since it is within the range of the notch 12a, the operating arm 11b is
There is no problem in raising and lowering the sliding member 12. As described above, with the lock of the present invention, the position of the dead hub 11 can be freely moved.

The present invention is not limited to the above embodiments, and various design changes can be made within the technical scope of the present invention.

[0013]

As described in detail above, according to the lock of the present invention, a dead hub driven by a key or thumb turn, a sliding member driven up and down by the dead hub, and the sliding member. In a lock including a driven hub driven by the driven hub and a dead bolt engaged with the driven hub in a projecting manner, the dead hub is provided with a support portion movably and rotatably supported in a notched hole of the lock body. So
By moving the position of the dead hub, a single lock can handle locks of various sizes. Therefore, it is possible to achieve an extremely excellent effect in terms of inventory management.
