A strike inclined surface 39 formed on the claw pieces 41, 41 and connected to the side plate inclined surfaces 37a, 37b, 37c, 37d and going down to the inside of the adjustment block 29;
Comprising
The adjustment block 29 is fitted into the troquet space 17, the end surfaces of the side plate portions 33a, 33b, 33c, 33d are exposed from the strike hole 19 of the strike plate 7, and the claw pieces 41, 41 and the concave groove 43, 43 and the block pressing pieces 45, 45 and the concave grooves 43, 43 face each other in a substantially comb shape, and the side plate inclined surfaces 37a, 37b, 37c, 37d and the strike inclined surface 39 are substantially continuous. It is characterized by a flat surface.

In this strike hole adjusting structure, it is composed of parts with a small number of the troyoke 5, the strike plate 7, and the adjusting block 29, and the adjusting block 29 is replaced with the troyoke 5 with its posture changed, so that the stop surfaces 31a and 31b of the lock bolt 21 are replaced. , 31c, 31d, the inner surface positions of the side plate portions 33a, 33b, 33c, 33d can be variously displaced. Further, when the door is opened, after the lock bolt 21 hits the side plate inclined surfaces 37 a, 37 b, 37 c, and 37 d of the resin adjustment block 29, the lock bolt 21 is transferred to the strike inclined surface 39. That is, the first part of the bolt passage is contact between different materials.
Further, in this strike hole adjusting structure, when the lock bolt 21 retreats from the inside of the adjustment block 29 when the door is opened, the side plate inclined surfaces 37a, 37b, 37c, 37d and the strike inclined surface 39 are slidably contacted in this order.

According to the strike hole adjusting structure according to claim 1 of the present invention, the side plate portions of the adjustment block fitted into the troyoke are formed with different thicknesses, and the side plates are formed on the end surfaces of the side plate portions exposed from the strike holes. Since the inclined surface is formed and the strike inclined surface connected to the side plate inclined surface is formed on the side of the strike hole bolt guide one side, it can be composed of parts with fewer troyoke, strike plate and adjustment block. By simply changing the direction of the door, it is easy to prevent the door from rattling, and it does not use adjustment screws and does not expose the screws, so it looks good.When the door is opened, the lock bolt side is made of resin. After hitting the side plate inclined surface of the adjustment block, it can be transferred to the strike inclined surface and a smooth opening without catching can be realized.
Further, according to this strike hole adjustment structure, the strike inclined surface is formed on the plurality of claw pieces protruding from the side of the strike hole, and each of the claw pieces is fitted into the concave groove of the side plate inclined surface. Combining the substantially comb-tooth shape facing each other, it becomes a substantially continuous inclined surface, and when the door is opened, when the lock bolt retreats from the inside of the adjustment block, the side plate inclined surface and the strike inclined surface are in this order.

Further, when the door is opened, after the lock bolt 21 hits the side plate inclined surfaces 37 a, 37 b, 37 c, and 37 d of the resin adjustment block 29, the lock bolt 21 is transferred to the strike inclined surface 39. That is, the first part of the bolt passage is contact between different materials.

  Therefore, according to the strike hole adjustment structure described above, it is possible to easily prevent the door 1 from rattling by simply replacing the adjustment block 29 with the troyoke 5 and, in addition, the appearance of the adjustment screw and other screws does not appear. When the door is opened, the lock bolt side portion contacts the side plate inclined surfaces 37 a, 37 b, 37 c, 37 d of the resin adjustment block 29 and then moves to the strike inclined surface 39. The metal strike plate 7 and the resin adjustment block 29 when exiting from the adjustment block 29 which becomes the troyoke space 17 are made of different materials, so that the boundary part between the end faces Rather than being configured to face each other, the configuration is such that substantially comb-shaped shapes are combined facing each other, and the surface portions are mutually connected. By forming it so as to fall into the side, it becomes a substantially continuous surface with a small recess in the middle when viewed from the side, and the tip of the lock bolt 21 that moves on the slopes of both members 7 and 29 can pass smoothly and be caught. Smooth opening of doors can be realized.

  Further, when the door 1 is opened, the adjustment screw and the tool engaging portion thereof are not exposed on the surface of the strike plate 7 or the space 17 of the trolley 5, so that the appearance can be improved. It is also possible to prevent the adjustment unit from being mischievous. Furthermore, since it is difficult to cause the door 1 to rattle by operating the adjustment unit in a malicious manner, crime prevention can also be improved. Further, since the stop surfaces 31a, 31b, 31c and 31d are formed on the adjustment block 29 of a single block body, the stop strength of the lock bolt 21 can be increased, and this also improves crime prevention. it can.
