Description

[Detailed Description of the Invention] This invention relates to a door lock strike device that is installed in a door lock mechanism of an entrance building material such as a door.

Generally, a door locking mechanism is formed by a protruding member such as a latch that slides in and out from the end face of the door on the opening/closing side toward the stile, and a strike device on the stile that engages and locks the protruding member. However, in recent house construction, prismatic vertical frames made of metal angle plates are often used, and decorative doors that give a sense of solidity and luxury are mainly used for doors installed at entrances. The present invention is mainly directed to the striper device in this type of motor.

By the way, the formation mode of the conventional strike device includes (a
), a structure in which a strike opening is punched out on the door stop surface of the stile, and a box-shaped cover is welded to the back side; (b), in addition to the structure in the previous section, decorations are provided around the strike opening. Structures in which strike plates are stacked are known, but with the structure described in item (a) above, it is difficult to adjust the relative position between the strike opening and the door, so it is difficult to adjust the relative position of the strike opening and the door. Not only is the workability of installing the door poor, but the strike opening is directly visible from the outside and looks unsightly.On the other hand, according to the structure in item (b) above, in addition to the above-mentioned drawbacks, the thickness of the pelmet is not enough to cover the door stop surface. This has the drawback that the gap creates a gap, which not only detracts from the aesthetics but also poses a safety problem.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and the purpose of the present invention is to provide a door that is easy to adjust the relative position of the door during installation, and has a beautiful appearance. Our goal is to provide a lock strike device.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

As shown in FIGS. 1 to 6, the strike device of the embodiment is formed on the doorstop surface 3 of a prismatic vertical stile 2 made of a metal angle plate on the opening/closing side of a left-hand swinging door 1, that is, on the left side of the drawing. , and the front side from the door stop surface 3 of the vertical stile 2 is L
A recessed step 4 is formed in the shape to provide a space for receiving the buffer resin piece 5 of the door end plate 1a, and a folded overhang 6 is formed on the depth side from the door stop surface 3. ing.

By the way, as shown in FIG. 4, in the portion of the door stop surface 3 facing the door latch 7, a rectangular recessed surface 3a that is in contact with the side edge of the recessed stepped portion 4 is formed by drawing process. , a vertically longitudinal strike opening 8 is punched out in the intermediate depth of the recessed surface 3a, and each vertical line of the strike opening 8 is cut off in a daruma shape to communicate with a screw through hole 8a. It is molded.

On the surface of this recessed surface 3a, a decorative plate 9 with a flange 9a is superimposed on the same plane as the doorstop surface 3, and the decorative plate 9 has a narrow width that communicates with the strike opening 8. window hole 1
0, and a mounting hole 9 consisting of a countersunk hole communicating with the screw through hole 8a.
b is perforated, and an edge plate 9c projects inward from the window edge in the longitudinal direction of the window hole 10.

Furthermore, this decorative board 9 is lined with a toro cover 11 that sandwiches the recess m 3 a, and the toro cover 11 has a rectangular dish part 11a circumscribing the edge 9c of the decorative board 9, and upper and lower flange parts. 11b, and each flange portion 11b has a protruding snap screw hole 11c.
is molded.

Thus, each of the upper and lower mounting screws 12, which are inserted through the mounting hole 9b and loosely passed through the screw through hole 8a, are screwed into the snap screw hole 11c or a nut on the back of the hole.
The decorative plate 9 and the cover 11 are fastened to the recessed surface 3a while sandwiching the recessed surface 3a, and the fastening position is between the cutout surface of the strike opening 8 and the screw through hole 8a. It is possible to freely adjust the vertical direction and the depth direction within the range.

In the fixed position, the decorative plate 9 has an L-shaped bent flange 9a on the front edge of the open side that protrudes along the front surface of the recessed step 4 of the vertical stile 2, and the second As shown in the figure, a door end plate 1a is fitted onto the open end surface of the door 1.
The front end protruding edge is bent into an L shape along the front surface of the flange 9a of the decorative plate 9, so that it comes into contact with the flange 9a of the decorative plate 9 when the door 1 is in the closed position. It has become.

In the strike device of the embodiment configured as described above, when the door 1 is installed, the fastening position of the decorative plate 9 can be easily aligned with the door latch 7, and the decorative plate 9 can be aligned with the door stop surface. Since it does not protrude from 3, it does not spoil the appearance, and furthermore, when the door 1 is closed, the slope of the door latch 7 collides with the curved surface of the base of the flange 9a of the valance plate, so the door latch 7 It slides smoothly and does not cause unnecessary wear.

In the configuration of the above-mentioned embodiment, the screw through hole 8a of the recessed surface 3a is cut off in the shape of a hammer and communicated with the strike opening 8, but instead of this, a simple round hole may be used. The details of the shapes of the openings and through holes can be freely determined.

As described above, according to the door lock strike device according to the present invention, the decorative plate in which the window hole for fitting the door latch is formed is superimposed on the same plane as the doorstop surface of the metal vertical stile, and The strike device has a good appearance and is easy to work on site because the device is constructed by fastening the Toro cover and the decorative plate that line the decorative plate to the doorstop surface so that they can be moved and adjusted within the range of the recessed surface. This has the effect of improving the workability and marketability of the door construction material.

Further, according to the present invention, in the closed position of the door, the door end plate 1a is attached to the L-shaped collar portion 9a of the decorative plate 9 fixed together with the cover 11 to the vertical stile 2 forming the inner frame of the door opening. Therefore, when the door 1 is in the closed position, the position of the door latch 1 protruding from the end face of the door 1 and the strike opening window hole 1 of the valance plate 9
The position of 0 always matches regardless of the deviation in the mounting position of the decorative plate 9, which has the effect of making the building material good and efficient.

In addition, when the door 1 is closed, the door end plate 1a of the door 1 comes into contact with the flange 9a of the decorative plate 9, and since the contact area is small, there is less impact when the door is closed. The front part of the door latch 7 is the door end plate 1.
Since it is covered by the protruding part a, it has an excellent effect in terms of safety.
