The strike may be attached using a reinforcing material attached to the frame material (same as above).

4 and 5 of Japanese Patent Laid-Open No. 2017-179779 JP2015-10398A

  When such prior art is used, for example, when the door itself or the latch mechanism on the door is replaced by repair work, the appropriate position of the strike on the frame material changes, and the cutout portion provided in the frame material has to be expanded, There was a problem that it was difficult to install the strike or the construction was extremely complicated.

  Therefore, in view of the problems of the prior art, an object of the present invention is to provide a strike member that can smoothly carry out the strike mounting work even in the repair work or the like by providing a cover member that covers the cutout portion of the frame material. It is to provide an adapter for mounting.

  In order to achieve this object, the structure of the present invention includes a cover member that is fixed to the frame member so as to cover the notch portion of the frame member, and a holding member that is attached to the inner surface side of the cover member. Has an opening adapted to strike, and the holding member holds the strike in the opening parallel to the surface of the cover member and is screwed.

  The cover member can be bent into an L-shaped cross section, and the opening can accommodate the strike lip.

  Moreover, a spacer may be interposed between the holding member and the inner surface of the cover member, and the torsion shield may be screwed together with the strike.

  According to such a configuration of the invention, the cover member is fixed to the frame member so as to cover the entire notched portion after the expansion even if the notch portion of the frame member is expanded during the repair work. The On the other hand, the strike is fitted into the opening of the cover member, and is held in parallel with the surface of the cover member via the holding member and screwed in the opening, so that the appearance of the frame material can be easily and neatly formed. Can be fixed in place. The holding member is attached to the inner surface side of the cover member. Therefore, the holding member is partially exposed to the outside through the opening until the strike is fitted into the opening of the cover member, but when the strike is fitted into the opening, the whole is concealed from the outside, and the whole There is no risk of damaging the appearance of.

  The cover member bent in an L-shaped cross section can cover the notch extending from the expected surface of the frame material to which the strike is attached to the finding surface without any hindrance, and is brought into contact with the two surfaces of the expecting surface and the finding surface. Thus, it can be more stably fixed to the frame member.

  Since the cover member is formed with an opening capable of accommodating a lip portion provided mainly in the strike for the latch bolt, there is no need to consider the wear resistance against the sliding of the latch bolt. This is because the latch bolt slides on the surface of the strike including the lip portion and does not substantially come into sliding contact with the cover member.

  If a spacer is interposed between the holding member and the inner surface of the cover member, the step from the surface of the cover member to the surface of the holding member to which the strike is screwed is matched to the thickness of the strike, By adjusting the strike surface in the opening to the same plane correctly, it is possible to realize a better appearance and usability.

  By screwing the trowel shield to the holding member together with the strike, there is an advantage that no special member is required to attach the trowel shield. Note that the step from the surface of the cover member to the surface of the holding member at this time is preferably adjusted to be equivalent to the sum of the thickness of the strike and the thickness of the mounting flange of the trowel.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The strike mounting adapter 10 (hereinafter simply referred to as the adapter 10) has a cover member 11 and a holding member 12 as main members (FIGS. 1 and 2). The adapter 10 is used together with the toro shield 22 when the strike 21 is fixed at an appropriate position of the frame member 31.

  The frame material 31 is, for example, a door frame for a door having a latch bolt, and is formed by bending a plate material. A protrusion 31a for door contact is formed at the center on the inner surface side of the frame member 31, and a notch 31d corresponding to the latch bolt on the door side extends from the expected surface 31b on the door opening direction side to the finding surface 31c. Is formed. However, the notch 31d may be appropriately expanded by, for example, a door repair work.

  The strike 21 is configured by forming an engagement hole 21a for a latch bolt in a vertically long plate material (FIGS. 1 and 3). A lip portion 21b is formed on one long side of the strike 21, and mounting countersunk holes 21c and 21c are formed above and below the engagement hole 21a.

  The toro shield 22 is provided with mounting flanges 22b and 22b vertically attached to a vertically long bottomed case body 22a that is slightly wider than the engagement hole 21a of the strike 21. Each mounting flange 22b is formed with a mounting through hole 22c, and the upper and lower through holes 22c and 22c are aligned with the upper and lower countersunk holes 21c and 21c of the strike 21 at the same interval.

  The cover member 11 is a vertically long plate material having an L-shaped cross section (FIGS. 1 and 2). The cover member 11 is formed to have a size that covers the notch 31d of the frame member 31, and has a wide portion 11b and a narrow portion 11c corresponding to the expected surface 31b and the finding surface 31c of the frame member 31, respectively. The wide portion 11b is formed with an opening 11a that fits the strike 21, and one long side of the opening 11a is open to the narrow portion 11c. In addition, mounting countersunk holes 11d and 11d are formed at both upper and lower ends of the wide portion 11b.

  The holding member 12 is configured by forming flag pieces 12b and 12b on the upper and lower sides by forming a notch 12a open on one side in an intermediate portion of a vertically long plate material. Screw holes 12c and 12c are formed above and below the notch 12a, and the distance between the screw holes 12c and 12c is equal to the distance between the through holes 22c and 22c of the toro shield 22 and the countersunk holes 21c and 21c of the strike 21. Yes.

  The holding member 12 is integrally attached to the inner surface side of the cover member 11 via spacers 13 and 13 (FIGS. 2 and 4). However, FIG. 4 (A) is a front view of the adapter 10, and FIGS. 4 (B) to 4 (D) are respectively a view corresponding to the arrow X in FIG. FIG.

  Each spacer 13 is a thin plate material corresponding to approximately half of each flag piece 12 b of the holding member 12. Therefore, the holding member 12 abuts one side of the cover member 11 on the side where the notch 12a is not formed on the inner surface side of the narrow portion 11c, and the notch 12a is located above and below the opening 11a. The spacers 13 are interposed between the surface of each flag piece 12b and the inner surface of the cover member 11 while being positioned so as to be symmetrically positioned in the direction, and are welded to the inner surface of the cover member 11 together with the spacers 13 and 13. ing.

  Therefore, an appropriate level difference d is formed between the surface of the cover member 11 and the surface of the holding member 12 exposed in the opening 11a (FIG. 4D), and the opening 11a and the holding member 12 of the cover member 11 are formed. A vertical window W is formed by overlapping the notches 12a (FIG. 1A), and screw holes 12c and 12c of the holding member 12 and countersunk holes 11d and 11d of the cover member 11 are aligned in a straight line above and below the window W. Arranged. However, the thickness and the number of the spacers 13 are adjusted so that the level difference d corresponds to the sum of the thickness of the strike 21 and the thickness of each mounting flange 22b of the trowel shield 22, and the window W is the trowel shield 22 It shall be suitable for the case body 22a.

  The strike 21 is fitted into the opening 11 a of the cover member 11, held in parallel with the surface of the cover member 11 by the holding member 12 in the opening 11 a, and the holding member 12 together with the toro shield 22 via the stop screws 23 and 23. (FIGS. 1 and 5). However, at this time, each set screw 23 is screwed into the screw hole 12c of the holding member 12 through the countersink 21c of the strike 21 and the through hole 22c of the trough shield 22. Further, the surface of the strike 21 after screwing can be finished in the same plane as the surface of the cover member 11. A step d between the surfaces of the cover member 11 and the holding member 12 is appropriately set, and the opening portion 11a for the strike 21 opened to the narrow portion 11c side of the cover member 11 is provided with a lip portion 21b of the strike 21. This is because they can be stored together.

  Thereafter, the cover member 11 is fixed at an appropriate position of the frame member 31 using the dish tapping screws 14 and 14 (FIGS. 1 and 6). However, FIGS. 6A and 6B are external views of the main part viewed from the direction of the face 31c and the surface 31b of the frame member 31, respectively, and FIG. It is a partial enlarged schematic cross-sectional view. In FIGS. 6A and 6B, a part of the frame member 32 as the upper frame connected to the upper end of the frame member 31 as the frame is also shown. Each dish tapping screw 14 is screwed into a pilot hole 31e provided in the frame member 31.

  The latch bolt B on the door end side of the door D is engaged by sliding on the surface of the strike 21 by closing the door D in the closed position (in the directions of arrows K in FIGS. 6B and 6C). The door D can be restrained by automatically engaging with the hole 21a.

  In the above description, the latch bolt B on the door D side combined with the strike 21 may be a dead bolt that linearly appears and disappears from the door end side of the door D, and appears and rotates while rotating from the door end side of the door D. A sickle-shaped deadbolt may be used. Further, the frame member 31 may be made of any material such as an extruded shape member or wood instead of the plate member shown in the figure. The door D is not limited to the door D as long as it includes a latch bolt or a dead bolt combined with the strike 21. The door D may be a door or window of any type including a sliding door.

  The present invention can be widely and suitably applied to strikes combined with latch bolts and dead bolts such as doors, doors and windows of any type.
