The cover piece 5 has a rectangular plate shape, and is fixed by being screwed into the screw hole 23 of the attachment piece 2 with a mounting screw 6 using screw insertion holes 50 formed on the left and right sides of the upper and lower ends. Note that 51 and 52 are through holes for the dead bolt 10 and latch bolt 11 to pass through.

Regarding the installation of the lock explained above, Figure 2~
This will be explained in detail with reference to FIG.

First, the lock main body 1 is inserted into the mounting hole 70 formed through the end plate 7 of the door, and is placed in contact with the front surface of the end plate 7 of the upper and lower mounting pieces 2. In addition, in the end plate 7, there are lock mounting holes 71 above and below the mounting holes 70.
is formed, and a back plate 7 is formed on the back surface of the end plate 7.
A pair of upper and lower mounting screw holes 73 are formed in the back plate 72 at positions corresponding to the mounting holes 71.

When the presser members 3 are applied to the front surfaces of the upper and lower mounting pieces 2, the spring portions 32 of the presser members 3 are inserted into the elongated holes 20 of the mounting pieces 2, as shown in FIG. Since the tip of the presser member 3 contacts the end plate 7 of the door, the tooth-shaped uneven portion 31 of the presser member 3
is floating on the front surface of the mounting piece 2, and the holding member 3 is movable in the vertical direction along the elongated hole 20.

In this state, the presser member 3 is moved up and down and positioned so that the screw insertion hole 30 of the presser member 3 faces the front surface of the mounting screw hole 73 on the door side. Note that the holding member 3 can be positioned using the scale 22 formed on the mounting piece 2.
If you position the presser member 3 according to the pre-measured pitch of the mounting screw hole 73 on the door side,
Work is accurate and positioning is easy.

After that, by inserting the mounting screw 4 into the screw insertion hole 30 of the holding member 3 and screwing the mounting screw 4 into the mounting screw hole 73 on the door side, the mounting piece 2 is held down by the holding member 3, The lock body 1 is attached and fixed to the end plate 7 of the door. At this time, as shown in FIG. 2, the tooth-shaped uneven portion 31 of the holding member 3
Since the presser member 3 is engaged with the tooth-shaped uneven portions 21 of the presser member 3, the presser member 3 is fixedly attached in a securely fixed position without moving in the vertical direction.

Among the lock attachment mechanisms described above, the lock main body 1 is used by being attached to the end face of a door, in addition to the illustrated box lock. It is also applicable to sickle locks and other types of lock structures.

As the mounting piece 2, a thin metal plate bent and formed to form a diagonal portion forming the tooth-like uneven portion 21 is preferable in terms of ease of manufacture and light weight, but a thick plate material is preferable. It can also be formed by cutting or casting (see FIG. 5).

Furthermore, if the tooth-shaped uneven portion 21 is formed on the inclined surface of the mounting piece 2, the engagement with the tooth-shaped uneven portion 31 of the presser member 3 and the release of the engagement will be smooth.
Although the overall thickness can be made thinner, the tooth-like uneven portion 21
It is also possible to form it on the horizontal or vertical surface of the mounting piece 2.

For example, in the modification shown in FIGS. 5 and 6, tooth-shaped uneven portions 21 are formed on the horizontal surfaces of the mounting piece 2 on both sides of the long hole 20, and tooth-shaped uneven portions 31 are formed on the back surface of the holding member 3. and press the presser member 3.
The position is fixed. In the case of the above modification, the entire presser member 3 is formed into a piece-like shape made of a rigid metal or the like, and a spring member 33 made of an elastic metal plate or the like is provided separately from the presser member 3.
are arranged on the back surface of the presser member 3. and,
The spring member 33 has a screw insertion hole 34 in the center.
At the same time, both ends in the longitudinal direction are bent to form a substantially V-shape toward the back side of the presser member 3, so that it can be elastically deformed.

In addition, in the modified example shown in FIGS. 7 and 8,
Both sides of the elongated hole 20 of the mounting piece 2 are bent vertically, and a tooth-like uneven part 31 is formed on this vertical surface, and the presser member 3 has a tooth-like uneven part at the left and right side ends, respectively. 31 is formed. In this modification, a coil spring-like spring member 35 is formed separately from the presser member 3 and is placed in a storage hole 36 formed on the back surface of the presser member 3. An annular projection 37 is provided on the outer periphery of the storage hole 36 of the presser member 3.
is formed, and this annular projection 37 fits into the long hole 20 of the mounting piece 2 to smooth the movement of the presser member 3.

The mounting piece 2 is designed such that when the holding member 3 is attached, the holding member 3 does not protrude beyond the front surface of the mounting piece 2 to make it easier to attach the cover piece 5. A space in which the presser member 3 can be accommodated may be formed on the side.

Next, as the presser member 3, the above-mentioned FIGS.
As in the embodiment shown in FIG. 4, it is preferable that the entire spring portion 32, including the spring portion 32, is integrally formed from a spring-like metal plate because it is easy to manufacture and can be formed compactly. As in the modification shown in FIG. 8, the presser member 3 and spring members 33, 35
It is also possible to form it from a separate member. The tooth-shaped uneven portion 31 formed on the holding member 3 can be freely formed into an appropriate uneven shape such as a triangular sawtooth shape, as long as it can engage with the tooth-like uneven portion 21 of the mounting piece 2 and prevent vertical movement. can. As for the number of convex portions, that is, the number of ridges of the tooth-shaped uneven portion 31, it is sufficiently effective if there are two ridges as shown in FIG. It is.

Furthermore, if the parts 32 and 37 of the holding member 3 or the spring member 33 are fitted into the long hole 20 of the mounting piece 2, the holding member 3 can be easily moved along the long hole 20, and the overall thickness can be reduced. Although it can be constructed thinly,
The spring part 32 of the holding member 3 is in contact with the surface of the mounting piece 2, the spring member 33,
It is also possible to use a structure in which 35 comes into contact with the surface of the mounting piece 2.

Note that the above-mentioned presser member 3, spring members 33, 35, etc. may be made of metal, or may be made of hard synthetic resin.

<Effects> According to the mounting mechanism of this invention configured as described above, the long hole 20 for inserting the mounting screw 4 is formed in the mounting piece 2 extending up and down the front surface of the lock body 1, and the mounting A presser member 3, into which a mounting screw 4 is inserted, is used to attach and fix the piece 2 to the end plate 7 of the door.
By moving it up and down along the elongated hole 20, the pitch between the upper and lower pair of mounting screws 4, 4 can be adjusted.
It can be adjusted and changed as desired.

Therefore, the pitch spacing of the mounting screw holes 72 formed in the end plate 7 of the door has extremely high flexibility, and can easily be adapted to the mounting pitch of any commonly used door. This is extremely convenient when replacing or repairing locks.

The mounting piece 2 is provided with tooth-like uneven portions 21 on both sides of the elongated hole 20, and the presser member 3 is also provided with tooth-like uneven portions 31. By meshing, the mounting positions of the presser member 3 and the mounting screws 4 can be reliably prevented from shifting in the vertical direction, making it possible to install the lock firmly and preventing the occurrence of misalignment or looseness during installation and use. Nor.

Furthermore, since a spring mechanism consisting of a spring portion 32 or spring members 33, 35, etc. is configured on the back surface of the presser member 3, the mounting screw 4
When it is loosened, the presser member 3 is raised on the surface of the mounting piece 2 due to the spring mechanism.
Since the engagement between the tooth-like uneven portion 31 of the holding member 3 and the tooth-like uneven portion 21 of the mounting piece 2 is released, the holding member 3 and the mounting screw 4 can be moved freely, and it is possible to adjust the mounting position and once installed. Readjustment of the mounting screws 4 can be easily performed.

When the mounting screw 4 is screwed into the mounting screw hole 72 of the end plate 7 of the door, the mounting screw 4 and the holding member 3 press the elastically deformable spring mechanism and deform it into a flat shape. If you let me,
The tooth-like uneven portion 21 of the holding member 3 and the tooth-like uneven portion 31 of the attachment piece 2 can be reliably engaged. In addition, since the spring mechanism always applies an elastic pressing force to the threaded portion of the mounting screw 4 and the mounting screw hole 72, it also functions as a kind of spring washer, and the mounting screw 4 It can also exhibit a loosening effect.

As mentioned above, the lock installation pitch can be adjusted freely, the adjustment work is easy, the adjustment range is wide, and the lock installation condition is reliable and strong.
It can exhibit various excellent practical effects.
