In addition, the distance from them to the axis O of the cam plate 31, that is, the amount of displacement of the below-described rotating case on the follower side is changed step by step.

That is, the engagement surface 32a, 32b, 32c, 32d, from 32e, eccentricity h ₀ to h to the base circle B _s of the cam plate 31 and concentric
_4, h ₀ is zero, i.e. the engagement surface 32a forms the tangent of the base circle B _s, than this based on the _{h 1, h 2 = 2h 1} , h 3 = 3h 1, h 4
= 4h ₁ . In the figure, 33 is a cross-shaped concave groove formed on the end surface of the cam block 32, into which a tool such as a screwdriver can be inserted.

A rotating case 34 is fixed to the bottom of the case 20.
20 is housed movably in the direction orthogonal to the longitudinal direction, and via a spring 35 interposed between the cases 20 and 34,
It is biased toward the outside of the door 10.

The case 34 is formed in a substantially box shape as shown in the drawing, a through hole 36 into which the cam block 32 can be inserted is formed at one end of the bottom surface thereof, and a long hole-shaped notch 37 is formed in the hole 36. It is formed along the moving direction of 34.

Further, between the pair of side pieces 41, 41 of the movable case 34, the roller 42 is rotatably supported at the end opposite to the engaging piece 40,
The locking rod 13 can be engaged. As shown in FIG. 2, the roller 42 is attached so as to be unevenly distributed on one side of the door frame 7, that is, on the outside in the embodiment, and the rear peripheral surface of the roller 42 is provided with respective locking rods 13, 14, 15.
Can be engaged with.

(Operation) For example, each of the locking rod receivers for the door configured as described above is
The door frame 7 is fixed in advance at a predetermined position opposite to 13, 14, 15 and is installed at a predetermined position at the same time when the frame 7 is attached.
In this case, the respective locking rod receivers 16, 17, 18 are attached so that the rollers 42 are unevenly distributed on one side of the door frame 7, that is, on the outside in the embodiment, as shown in FIG.

Of course, in addition to the mounting method described above, it is also possible to mount the locking rod receivers 16, 17, 18 after mounting the door frame 7 in the above-described manner.

In this way, the attached locking rod receivers 16, 17, 18 are connected through the opening window 21 of each cover 19 as shown in FIGS. 2 and 6.
The inside is opened to the outside of the door frame 7, and the cam block 32 and the screw 38 are exposed in the inner part thereof, and the above-mentioned locking rod receiving
After mounting 16, 17 and 18, the door 10 is mounted via the hinge 9.

In this case, since the cam block 32 has the concave groove 33 formed on the end surface, the number of parts can be reduced as compared with the conventional method which requires the cam and the screw.

When the door 10 is mounted as described above, the contact state between the end peripheral surface of the door 10 and the door rest 7a loses uniformity due to the mounting condition of the door frame 7 and the door 10, and the like. When the stop rods 13, 14, 15 are locked, the airtightness and the soundproofing effect on the peripheral surface of the end of the door 10 become different, and the adjustment or correction is required.

The adjustment or correction is performed by the locking rod receivers 16, 17, 18, and in that case, using a suitable tool such as a screwdriver, insert this into the locking rod receiver 16 through the opening window 21, for example,
First, the screw 38 is loosened to allow the movable case 34 to move.

In this way, the case 34 is moved leftward in FIG. 5 by the spring 35, and is stopped when the ends of the side pieces 41, 41 come into contact with the inner surface of the case 20, while at this stop position. The inner surface of the engagement piece 40 engages with the current engagement surface of the cam block 32, 32a in the case shown, and presses it in the above direction.

Next, insert the screwdriver into the groove 33 of the cam block 32,
Push this in the appropriate direction to engage the engaging surfaces 32a, 32b, 32c, 32
One of d and 32e is engaged with the inner surface of the engagement piece 40. In this case, as the cam block 2 rotates, the engagement piece 40 that engages with the ridge is pushed and moved, and this displacement is caused by the spring 35.
Absorbs.

Thus, when the engaging piece 40 engages with the engaging surface 32b, the engaging piece 40 is
Move to the right by the difference of those eccentric distances, that is, h ₁ ,
The movable case 34 integrated with the engagement piece 40 and the roller 42 move in the same direction.

And after this, temporarily fix the screw 38 through the driver,
The suitability of the adjustment is confirmed by restraining the displacement state of the movable case 34 with respect to the fixed case 20.

The above-mentioned confirmation work is performed by, for example, closing the door 10 and locking the locking rods 13, 14, 15 while the lever handle 11
Is held, and this is pushed and pulled inward and outward of the door 10, and the presence or absence of rattling sound between the door 10 and the door rest 7a at that time is confirmed.

That is, if the above adjustment is good, the door seal 8 prevents the rattling noise, and if the adjustment is insufficient, the rattling noise is generated.

If the adjustment is insufficient, the screw 38 is loosened again, and the cam block 32 is rotated again to bring the predetermined engagement surface into the engagement piece.
Engage 40.

At that time, referring to the rattling sound at the time of confirmation, for example, when the rattling sound is large, the engaging surfaces 32d or 32e are engaged with the engaging pieces 40, while when the rattling sound is small, the engaging surface is
32b is engaged with the engagement piece 40.

With the above arrangement, for example, when the engagement surface 32d and the engagement piece 40 are engaged, the movable case 34 moves to the right in FIG. 7 by 3h ₁ compared to when the engagement surface 32b is engaged. , Also the engaging surface 32e
When engaging the engaging piece 40 with the engaging piece 40, the movable case 34 moves in the same direction for 4h _{1 as} compared with the time when engaging the engaging surface 32b.
During engagement of the c and the engaging piece 40, it moves the movable case 34 is to 2h ₁ minute in the same direction.

That is, when the cam block 32 is rotated clockwise in FIG. 7 in this manner, the movement amount of the movable case 34 is gradually increased stepwise, and when the cam block 32 is rotated counterclockwise, the movement amount of the movable case 34 is increased. Is gradually reduced in a stepwise manner, so that the adjustment work can be easily performed by appropriately turning the volume of the rattling sound as a guide.

In this case, since the engagement surfaces 32a to 32e are formed flat, the position of the engagement piece 40 that engages with the engagement surfaces 32a to 32e is stable, and the position of the roller 42 integrated with the movable case 34 is stable.

Moreover, since the engagement surfaces 32a to 32e are provided on the entire peripheral surface of the cam block 32, the rotation range of the cam block 32 becomes compact as compared with the case where the engagement surfaces 32a to 32e are formed on a part of the peripheral surface. The miniaturization of the movable case 34 accommodating 32 is promoted,
The fixed case 20 that houses the case 34 becomes compact.

Further, since the engagement surfaces 32a to 32e are exposed to the outside, it is possible to confirm whether or not the adjustment state is appropriate and the situation, and the above adjustment can be surely performed.

Further, the engaging surfaces 32a to 32e are arranged so as to be engageable with the engaging piece 40, and the displacement of the cam block 32 is directly transmitted to the movable case 34 so that the position of the roller 42 can be adjusted. Thus, when the movable case 34 moves, the roller 42 approaches the side of the locking rods 13, 14, 15 and engages with the rods 13, 14, 15 or at the engaging position as much as possible. approach.

Then, the adjustment state is confirmed as described above, and when the favorable adjustment state is confirmed, the screw 3 is tightened and the movable case 34 is fixed to the adjustment position. Such an adjusting operation is performed on each of the locking rod receivers 16, 17 and 18, and a series of adjustments are completed by finishing these operations.

As described above, according to the present invention, the position of the roller 42 with respect to the locking rods 13, 14, 15 can be adjusted by rotating the cam block 32. Solving the problem that could not improve the airtightness or soundproofing effect, and in the above adjustment, since the roller 42 is engaged or brought as close to the engagement position as possible, the movement of the locking rod is prevented or The gap between the door 10 and the door rest 7a is suppressed as small as possible, and the airtightness or soundproof effect between them is improved.

Further, in the present invention, as described above, the screw 38 and the cam block
Since the engaging surfaces 32a to 32e of 32 and the recessed groove 33 are exposed in the inner portion of the opening window 21, the airtightness of the door 10 is not limited to the above-described time when the door 10 is attached, but also due to long-term use. Or, even if the soundproof effect is lowered, the door 10 can be easily adjusted and corrected without removing the door 10 one by one.

(Effects of the Invention) Since the door locking rod receiver of the present invention has the through hole and the engaging piece formed at the position opposite to the roller of the movable case as described above,
A locking rod can be received between the roller and the engaging piece in the movable case, and a cam block is arranged inside the through hole to form a plurality of flat engaging surfaces on the entire peripheral surface of the block. Therefore, the rotation range of the cam block can be downsized, the movable case and the fixed case can be made compact, and the door locking rod receiving can be made compact.

In addition, since each engagement surface of the cam block is formed flat and engaged with the engagement piece, the engagement between the engagement surface and the engagement piece is stable, and the roller moves through the movement of the movable case. It is possible to obtain a stable position adjustment and improve the airtightness and soundproofing effect of the door.

Further, according to the present invention, since a concave groove into which a tool can be inserted is formed on the end surface of the block, the number of parts is reduced as compared with the case where the cam block and the rotating member thereof are separately provided, and the engaging surface and Since the concave groove is exposed to the outside, the adjustment state of the cam block can be confirmed from the outside, and whether the adjustment is appropriate or the situation can be confirmed, so that the above adjustment can be reliably performed.

Moreover, since the respective engagement surfaces are arranged to be engageable with the engagement pieces and the displacement of the cam block is directly transmitted to the movable case so that the adjustment of the rollers can be adjusted, the structure for this can be simplified. There is a practical effect of.
