Reference numeral 22 denotes a screw hole for attachment to a door frame or another door, which is formed in the flanges 21 and 21.
[0010]
In the space formed by the strike plate 1 and the trowel 2, an adjustment plate 3 having an L-shaped cross section having a vertical fold line and an inner case 4 are mounted in a movable state sequentially from the inside. In other words, the trolley 2, the adjustment plate 3, the inner case 4, and the strike plate 1 are assembled in the order of arrows A, B, and C shown in FIG.
[0011]
After putting the adjusting plate 3 and the inner case 4 in the troyoke 2, the strike plate 1 is fixed so as to cover the troyoke 2, and the fixing means is caulking by burring, Welding or tightening with mounting screws can be used.
[0012]
As clearly shown in FIG. 5, the adjustment plate 3 having an L-shaped cross section is formed shorter in the vertical direction (longitudinal direction) than the inner method in the vertical direction (length direction) of the troyoke 2. In the troyoke 2, it can be moved in the vertical direction (vertical direction).
[0013]
The rising piece 31 provided on one side of the adjusting plate 3 (for example, the left side when viewed from the front in FIGS. 1, 4 and 5A) by bending or the like is formed between the side plate of the Troyoke 2 and the side plate of the inner case 4. It is designed to extend between them.
[0014]
In addition, the operation portion 32 formed of an integral protruding piece or recess provided on the front end side of the rising piece 31 can be hooked to the tip of a tool such as a screwdriver, so that it is exposed to the front side of the strike. It is.
[0015]
In the illustrated example, the operation portion 32 is viewed from the window 44 provided from the tongue piece 42 portion of the inner case 4 to the opening edge portion of the strike plate 1 to the outside.
[0016]
Reference numeral 35 denotes a relief hole provided in the rising piece 31 of the adjustment plate 3, and a later-described pressing spring 5 mounted between one side plate of the troyoke 2 and one side plate of the inner case is provided on the adjustment plate 3. It is for letting it escape when it is displaced.
[0017]
Further, an arbitrary number of guide inclined holes 33 into which protrusions 43 of the inner case 4 described later are movably fitted are formed in the main body portion of the adjustment plate 3. When two or more guide inclined holes 33 are provided, they are made parallel to each other.
[0018]
Further, the side of the guide inclined hole 33 on the side of the engaging portion 41 of the inner case 4, that is, the side of the inner case 4 on the side close to the engaging portion 41 is formed on the corrugated edge 34. The corrugated edge 34 is brought into contact with the body of the projection 43 of the inner case 4 in a normal state (see FIGS. 1 and 2).
[0019]
In the illustrated example, the adjustment plate 3 is guided by the inner surface of the trolley 2 and the outer bottom surface of the inner case 4, and is movable only in the vertical direction (arrow P direction) within the trolley 2.
[0020]
Next, the inner case 4 will be described in detail.
The inner case 4 has a box shape with an opening at the front, and the other side plate, for example, the right side plate, functions as an engaging portion 41 with which a back surface such as a latch bolt abuts.
[0021]
Both side portions of the opening of the inner case 4 are provided with tongue pieces 42 having an arbitrary number of flange shapes, and an arbitrary number of protrusions 43 having a low pin shape, that is, a disk shape, are provided on the outer bottom surface of the inner case 4. Projected. Each protrusion 43 is movably fitted into the corresponding guide inclined hole 33 in the adjustment plate 3 described above.
[0022]
The inner case 4 is narrower than the troyoke 2 and is movable only in the left-right direction (arrow Q direction) when viewed from the front.
[0023]
In the illustrated example, the movement of the inner case 4 in the left-right direction is slidably contacted between the outer surface of the inner case 4 and the inner surface of the troyoke 2, a partial tongue piece 42 of the inner case 4 and the guide groove 13 of the strike plate 1. And a movable fitting between the other tongue piece 42 of the inner case 4, the back surface of the strike plate 1, and the gap 23 provided between the front edge of the trowel 2.
[0024]
However, the guide means for the inner case 4 and the adjusting plate 3 are not limited to those of the embodiment, and can be arbitrarily designed.
[0025]
A compression conical spring or any other type of spring 5 clearly shown in FIGS. 2 and 4 is mounted between one side plate of the troyoke 2 and one side plate of the inner case 4 through a relief hole 35 of the adjustment plate 3. The inner case 4 is biased toward the other side plate of the troyoke 2.
[0026]
In short, the push spring 5 is for elastically pressing the projection 43 of the inner case 4 on the corrugated edge 34 of the guide inclined hole 33 in the adjustment plate 3 and engaging it in a stable state. In FIG. 4, reference numeral 45 indicates a spring stopper provided on one side surface of the inner case 4.
[0027]
In the strike of the present invention configured as described above, in order to move the inner case 4 in the left-right direction (the direction of the arrow Q) so that the engaging portion 41 occupies an appropriate position, a tool such as a screwdriver is used. The front end is locked to the operation portion 32 of the adjustment plate 3, and the operation portion 32 is moved upward or downward (arrow P direction) by a necessary distance.
[0028]
At that time, the adjusting plate 3 that linearly displaces together with the operation portion 32 guides the protrusion 43 of the inner case 4 through the guide inclined hole 33 and is allowed to move only in the left-right direction (arrow Q direction). The case 4 is displaced in the left or right direction against the push spring 5.
[0029]
By the above operation, the engaging portion 41 of the inner case 4 is adjusted so that an appropriate position is occupied with respect to the latch bolt or the like. After the operation, the corrugated edge portion 34 of the adjusting plate 3 is pressed by the pressing spring 5. And the protrusion 43 of the inner case 4 are securely engaged again.
[0030]
Therefore, in the inner case 4, the proper position without rattling with the latch bolt of the door is held in a stable state.
[0031]
When the operation portion 32 of the adjustment plate 3 is moved upward or downward with a tool such as a screwdriver, the inner case 4 is moved against one of the side plates of the trolley 2 against the push spring 5 by another hand before the operation. Since the engagement between the projection 43 of the inner case 4 and the corrugated edge 34 of the guide inclined hole 33 in the adjustment plate 3 is released during that time, the operation portion 32, that is, the adjustment plate 3 The moving operation can be performed very lightly. Using this method makes the adjustment operation easier.
[0032]
Although the adjustment strike according to the present invention shown in FIG. 1 is shown as being used for a door that is opened to the left hand, if it is turned upside down, it can be used as it is for a right hand door. it can.
[0033]
【The invention's effect】
The adjustment strike of the present invention described above has a simple structure with respect to function and a small number of parts.
[0034]
In addition, since the inner case can be moved in the left-right direction by moving the adjustment plate up and down from the outside with a tool such as a screwdriver, the engagement portion of the inner case occupies the proper position even after the strike is attached. It is easy to set to.
[0035]
Furthermore, once the inner case is set to an appropriate position, the projection of the inner case urged by the push spring and the corrugated edge of the guide oblique hole in the adjustment plate are securely engaged. There are various effects such as being held in that position in a very stable state over a long period of time.
