DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings. The adjusting strike of the present invention is used by being attached to another door in a door frame or a double door to engage a latch bolt and / or a dead bolt of a door lock when the door is closed.

FIGS. 1 to 3 show a first embodiment according to the first aspect of the present invention.
An embodiment is shown, and FIGS. 4 and 5 show a second embodiment according to the second aspect of the present invention.

In FIG. 1 to FIG. 3 showing the first embodiment, reference numeral 1 denotes a strike box having an opening 13 for receiving a latch bolt 20 and / or a dead bolt of a lock attached to a door 10, and a mounting screw. (Not shown), it is attached to the door frame 30 or another door of the double door.

The strike box 1 shown in FIG. 1 comprises a trowel 11 and a strike plate 12 shown in FIG. 3, and both of them 11 and 12 are attached to a door frame 30 or another door of a double door with common mounting screws. And are integrally joined.

Reference numeral 15 denotes a fitting hole for a mounting screw of the troyoke 11, which is provided on each of the upper and lower flange portions 14 of the troyoke main body having a box shape with an open front.

Reference numeral 16 denotes a screw fitting hole provided on each of the upper and lower sides of the strike plate 12. When the strike plate 12 and the Troyoke 11 are overlapped, the screw fitting hole 1 of the Troyoke 11 is formed.
5 is matched.

The strike box 1 has at least an engagement portion 3 with the latch bolt 20 and / or the dead bolt.
An adjustment frame 3 having, for example, a box shape and having a bottom plate portion 1 and a bottom plate portion 32 is provided. The adjustment frame 3 is guided in the strike box 1 so as to be movable only in the left-right direction when viewed from the front.

As guide means for moving the adjustment frame 3 in the strike box 1 in the left-right direction,
In the illustrated example, the tongue piece 33, 34, or 3 of the adjusting frame 3 that fits into the inner wall of the strike box 1, the recess 17 or the notch 18 of the strike box 1,
5 and the like play the role, but it goes without saying that the guide means for the adjustment frame can be arbitrarily designed and may be of other types.

The assembling of the trowel 11, the adjusting frame 3 and the strike plate 12 is performed in such a manner as to be superposed in the order of arrows P and Q in FIG.

The bottom plate 32 of the adjustment frame 3 as described above.
The adjusting screw 5 having a conical surface portion 51 on the distal end side and a tool engaging portion 52 for engaging the distal end of a driver or other operating tool on the outer end side (front side) is provided in the female screw hole provided at the front end. Screw together.

In the illustrated example, a female screw hole into which the main body portion (male screw portion) of the adjusting screw 5 is screwed is formed by subjecting the bottom plate portion 32 of the adjusting frame 3 to burring.

On the other hand, the bottom 19 of the strike box 1
That is, the receiving hole 4 having the V-shaped inclined edge portion 41 is provided in the bottom portion 19 of the toyoke 11. The receiving hole 4 can be provided in the bottom portion 19 of the strike box 1 so that the center line thereof is along the displacement direction (moving direction) of the adjustment frame 3, and a pair of V-shaped inclined edges 41, 41 are formed. It should be provided substantially symmetrically with respect to the center line.

The adjusting screw 5 is fitted into the receiving hole 4 of the strike box 1 at the conical surface portion 51 thereof, and further, the adjusting frame 3 is directed to the strike box 1 in the opening direction of the door 10 by a leaf spring or any other type. The conical surface portion 51 of the adjusting screw 5 is brought into contact with the V-shaped inclined edge portion 41 of the receiving hole 4 by being urged by the spring 6 or magnet means (not shown).

In the adjusting strike of the first embodiment according to the first aspect of the present invention, the adjusting screw 5 is simply turned clockwise or counterclockwise with a tool such as a screwdriver inserted through the opening 13 of the strike box 1 to provide a spring. 6 and the like, the conical surface portion 52 of the adjusting screw 5 abutting and engaging with the V-shaped inclined edges 41, 41 of the receiving hole 4 with the change of the screwing depth of the adjusting screw 5. Since the contact position is changed in the axial direction, the adjustment frame 3 can be moved to the left or right as viewed from the front as the diameter in the cross section of the conical surface portion 52 changes.

Here, the engaging portion 31 of the adjusting frame 3 is adjusted so that an appropriate position is occupied with respect to the latch bolt 20 or the like.
Rattling can be prevented from occurring.

Next, a second embodiment shown in FIGS. 4 and 5 will be described. In the second embodiment, members or portions indicated by the same reference numerals as those in the first embodiment of FIGS. 1 to 3 represent members or portions having the same effect.

Strike box 1 and adjustment frame 3
Since the overall shape and the assembling thereof are almost the same as those of the first embodiment, the description will be omitted here without duplication.

In the second embodiment, the adjusting screw 5 is screwed into the bottom 19 of the strike box 1, that is, the female screw hole provided in the bottom 19 of the trowel 11, and the adjusting screw 5 is connected to the outer end side (front side). A side) has a conical surface portion 51 and a tool locking portion 52 for engaging the tip of a driver or other operating tool.

In the illustrated example, the female screw hole into which the main body portion (male screw portion) of the adjusting screw 5 is screwed is formed by subjecting the bottom portion 19 of the strike box 1 to burring.

On the other hand, the bottom plate 32 of the adjustment frame 3
The receiving hole 4 having the V-shaped inclined edges 41, 41 is provided.

The receiving hole 4 can be provided so that the center line thereof is along the displacement direction (moving direction) of the adjustment frame 3, and a pair of V-shaped inclined edges 41, 41 are referenced to the center line. Are provided almost symmetrically.

Then, the adjusting screw 5 is fitted in the receiving hole 4 of the adjusting frame 3 at the conical surface portion 51 thereof. The conical surface portion 51 of the adjusting screw 5 is brought into contact with the V-shaped inclined edge 41 of the receiving hole 4 by being urged by a spring 6 of a type or magnet means (not shown).

In the adjusting strike of the second embodiment according to the second aspect of the present invention, the adjusting screw 5 is simply turned clockwise or counterclockwise with a tool such as a screwdriver inserted through the opening 13 of the strike box 1 to provide a spring. 6 and the like, the conical surface portion 51 of the adjusting screw 5 abutting and engaging with the V-shaped inclined edge 41 of the receiving hole 4 of the bottom plate portion 32 of the adjusting frame 3 has a screwing depth of the adjusting screw 5. The contact position in the axial direction is changed in accordance with the change, so that the adjustment frame 3 can be moved rightward or leftward when viewed from the front as the diameter in the cross section of the conical surface portion 52 changes.

Here, also in the second embodiment, the engaging portion 31 of the adjustment frame 3 is adjusted so that an appropriate position is occupied with respect to the latch bolt 20 and the like. Rattling can be prevented from occurring.

[0031]

According to the adjusting strike of the present invention described above, the moving direction of the adjusting frame through the adjusting screw between the strike box and the adjusting frame during its use, that is, the left-right direction when viewed from the front. However, even when a force is applied relative to the above, a rotational moment is generated in the abutting engagement portion between the conical surface portion of the adjusting screw and the pair of V-shaped inclined edges in the strike hole or the receiving hole of the adjusting frame. Since the adjustment screw is offset, the adjustment screw does not rotate in either direction, so that once the adjustment frame is adjusted, it does not shift from its proper position and is held in a stable state for a long time. It has the effect of

Further, the adjustment strike of the present invention has good operability in the adjustment operation, has continuity in the adjustment displacement of the adjustment frame, and has an advantage that it can be set to an optimum position. There is.
