The sickle piece 7 is provided in order to enhance the crime prevention function. When locked, the sickle piece 7 is placed on the inner wall surface of the front wall 26 of the movable core 3 so as to overlap the dead bolt 6 in the horizontal direction as shown in FIG. On the other hand, the tip portion can be engaged.

  FIG. 1 shows a case where a door frame 1 is fixedly attached with a troyoke 2, a frame-like movable core 3, a cover-like strike 4, and a pair of upper and lower holding plates 8, 8 which are novel matters of the present invention. The normal use state in is shown. Note that portions not related to the specific requirements of the present invention are omitted.

(2) Constituent member of lock receiving device-door frame 1
The constituent members of the lock receiver will be described in order with reference to FIG. First, the simplified door frame 1 will be described. Only a part of the rectangular tube portion 10 facing the vertical end surface of the door 5 is shown. 10a is a front wall, 10b is a back wall, 10c and 10c are left and right side walls, 11 is a vertically long receiving port formed in the front wall 10a, and 12 is on the upper and lower parts on the left side so as to communicate with the receiving port. Strike cutout grooves 13 cut in a vertical line shape are upper and lower screw holes formed in the front wall 10a in the vicinity of the cutout grooves 12 and 12.

(3) Troyoke 2
Next, Troyoke 2 will be described. The shape of Troyoke 2 is generally the same as that of ordinary ones. That is, when the portion of the troyoke 2 is divided, the rectangular case portion 15 of the front opening that enters the reception opening 11 of the door frame 1 and the upper and lower ends of the rectangular case portion 15 that are integrally formed with the upper and lower ends of the opening 16 side, respectively. The mounting pieces 17 and 17 are formed with through-holes 18 and 18 that coincide with the screw holes 13 and 13 of the door frame 1.

  Thus, in this embodiment, a total of four left and right holding pin relief notches 20 and 20 are formed in the upper and lower portions of the left and right side walls 15c and 15c of the rectangular case portion 15, respectively. As shown in FIG. 1, these notches 20 are related to a pair of upper and lower movable core holding pins (engagement pins) 21 and 21, respectively.

  That is, each holding pin 21 penetrates the pair of left and right relief cutouts 20, 20. In a normal use state, the notch portion 20 is based on a small semicircular arc-shaped small engagement groove 20a that partially engages with the outer peripheral surface of one holding pin 21 and a small engagement groove 20a as a reference edge. And a holding pin relief portion 20b that expands in the direction of the back wall 15b of the rectangular case portion 15 and widens (for example, rectangular shape, vertical long hole shape, etc.).

  In addition, small engaged portions (for example, small engagement holes, small grooves formed on the inner wall surface) 22 and 22 are formed at positions near the upper and lower portions of the left and right side walls 15c and 15c.

(4) Movable core 3
Next, the movable core 3 will be described. As shown in FIG. 3, the movable core 3 is formed in a box shape having a plurality of openings. That is, 3a and 3a are upper and lower front walls, and in this embodiment, when locked, the tip of the sickle piece 7 can be engaged with the inner wall surface of one of the front walls 3a (sickle). The piece 7 is engaged with the movable core).

  3c and 3c are left and right side walls, 25 is a vertically long front opening formed between the front walls 3a and 3a, 26 is upper and lower recesses formed in the front walls 3a and 3a, and 27 is these recesses. The upper and lower screw holes formed on the left and right side walls 3c and 3c, the holding pin insertion holes formed on the upper and lower sides of the left and right side walls 3c and 3c, respectively, and the left and right side walls 3c and 3c near the upper and lower parts. Small engagement portions (for example, small protrusions) formed and respectively engaged with and disengaged from the small engaged portions 22 and 22 of the Troyoke 2 described above, 31 is an upper and lower rear opening, and 32 is a rear opening 31 divided vertically. In this way, it is a receiving piece for a locking piece having a U-shaped cross section fixedly provided in the center of the left and right side walls 3c, 3c.

  By the way, as shown in FIG. 1, the movable core 3 is held in a loosely fitted state on the trowel 2 via the engaging portion 30 and the upper and lower holding pins 21 and 21. When the movable core 3 is loosely fitted to the trowel 2, the small protrusion-like engaging portions 30, 30 of the movable core 3 are engaged with the small engaged portions 22, 22 of the troyoke 2, respectively. Accordingly, the troyoke 2 and the movable core 3 are integrated with each other, though temporarily.

  Further, a slight clearance (for example, about 7 mm) is set between the lower surface of the locking piece 6 entering the movable core 3 and the horizontal upper plate portion 32a of the receiving piece 32. The piece 32 receives the impact force when the lower surface of the dead bolt 6 and the horizontal upper plate portion 32a collide with each other due to the deformation of the door frame. Moreover, since the sickle piece 7 is also provided in the present embodiment, when the sickle piece 7 rises while retracting simultaneously with the locking piece 6, the upper edge portion of the front opening 25 of the movable core 3 has both locking pieces. The impact force is received from 6,7.

  Therefore, the movable core 3 can be moved back and up via the horizontal upper plate portion 32a of the locking piece receiving piece 32, as will be described later, when both of the locking pieces 6 and 7 have moved to the trolley 2 side. It becomes.

(5) Strike 4
Next, the cover-like strike (cover plate) 4 will be described. 35 is a cover body, 36 is a deformable inclined upper and lower end connected to the cover body in the upward and downward directions, and 37 is provided so as to be orthogonal to the cover body from the right end of the cover body. The approach engaging side wall 38 is a front opening having the same shape as the front opening 25 of the movable core 3, and 39 is formed in the upper and lower portions of the cover main body and is fixed to strike that matches the screw holes 27, 27 of the movable core 3. This is an insertion hole for the tool 40.

  The strike 4 does not have the other side wall facing the entry engagement side wall 37. Further, the upper and lower projecting end portions 37a and 37a and the inclined upper and lower end portions 36 and 36 of the approach engagement side wall 37 engaged with the notch groove 12 of the door frame 1 are cut off from each other.

  Therefore, the inclined upper and lower end portions 36 and 36 of the strike 4 that covers the Troyoke fixing devices 41 and 41 are, for example, the substantially horizontal direction X that presses the strike 4 against the door frame side, or the reverse that presses the strike 4 against the end face side of the door 5. It can be deformed when an impact force in the direction X is applied.

(6) Holding plate 8
As shown in FIG. 1, the holding plate 8 is positioned in the upper and lower gaps 46 and 46 set between the upper and lower inner wall surfaces of the troyoke 2 and the upper and lower walls 3 b and 3 b of the movable core 3. It is arranged in a line target state. The line object here means the upper and lower line objects when the horizontal line passing through the center of the movable core 3 is the object center line.

  The holding plate 8 of the present embodiment constitutes a “one set” in a pair of upper and lower sides and is formed in a cross-section fishhook shape. The base end portions 8a and 8a of the holding plates 8 and 8 are fixed to the upper and lower walls 3b and 3b of the movable core 3 via fixing means (for example, male screws) 9 and 9, respectively, and the hook-shaped tip portion 8b. Are in contact with the upper and lower inner wall surfaces 2b, 2b of the troyoke 2, respectively. Therefore, although not indicated in particular, attachment holes are formed in appropriate portions of the holding plate 8 and the upper and lower walls 3b, 3b of the movable core 3, respectively.

  Accordingly, the tip portions 8b, 8b of the pair of upper and lower holding plates 8, 8 are elastically deformable (elastic deformation function) corresponding to the vertical movement of the movable core 3, as shown in FIG. Moreover, as shown in FIG. 8, these tip portions 8b and 8b are used to immediately secure the original holding state by the elastic restoring force of the material itself at the moment when the external impact force disappears after the occurrence of the earthquake. It works (elastic return deformation function).

(7) Combination of each member Next, the combination of each member is demonstrated easily. First, the troyoke 2 and the movable core 3 are combined together. At this time, the engaging portions 30 and 30 of the movable core 3 are engaged with the engaged portions 22 and 22 of the trolley 2, and the upper and lower holding pins 21 and 21 are connected to the upper and lower cutout portions 20 and 20 of the trooke 2 and the movable core. 3 are inserted into the upper and lower insertion holes 28, 28, respectively.

  Next, the case portion 15 of the troyoke 2 is fitted into the receiving port 11 of the door frame 1, and the upper and lower mounting pieces 17, 17 are brought into surface contact with the front wall 10 a of the door frame 1. Then, the Troyoke fixing tools 41 and 41 are screwed into the screw holes 13 and 13 of the door frame in accordance with the through holes 18 and 18 of the movable core. As a result, the trolley 2 is fixed to the door frame 1.

  Next, the strike 4 is made to cover the upper and lower mounting pieces 17, 17 of the troyoke 2. Thereafter, the strike fixtures 40, 40 are screwed into the screw holes 27, 27 of the movable core 3 in accordance with the insertion holes 39, 39. When screwed, the upper and lower holding pins 21 and 21 are surely engaged with the small engagement groove 20a of the trowel, so that the members 2, 3 and 4 are integrated as shown in FIG. In addition, there is some rear lance between the upper surface of the locking piece 6 and the upper edge of the front opening 28 of the strike 4.

  FIG. 7 shows an example of the moving direction of the movable core 3 when an earthquake occurs that causes the door frame 1 to deform. As described above, when an earthquake occurs, for example, the locking piece 6 tilts or descends due to the deformation of the door frame 1, and the lower surface thereof and the horizontal upper plate portion 32a of the receiving piece 32 collide with each other. In this case, the movable core 3 receives a strong impact force from the locking piece 6 through the receiving piece 32.

  Therefore, in the state of use of FIG. 1, an out-of-plane external force (external impact force) in the direction X intersecting the wall surface of the cover body 35 of the strike 4 is generated at the same time. When external force in the direction Y parallel to the wall surface (external impact force) is generated at the same time, the strike 4 is shockedly pressed in the horizontal to vertical direction between the door frame 1 and the door 5. Therefore, the upper and lower end portions 36 and 36 are displaced outwardly and slide the front wall 10a of the door frame 1 in the joystick direction X and the vertical direction Y. At this time, the small engagement protrusions 30, 30 of the movable core 3 are deformed or broken and come out of the small hole 22 of the trojoke 2.

  However, since the troyoke 4 and the movable core 3 are integrated with each other via the holding pin 21, the troyoke 4 and the movable core 3 are moved back and forth in multiple directions to the rear gap 45 and the upper and lower gaps 46 in the troyoke 1. To do. Therefore, the movable core holding pins 21 and 21 shift from the small engagement groove 20a of the notch 20 of the troyoke 2 to the wide holding pin escape portion 20b in response to the backward and upward movement of the movable core 3. The action of the holding plate 8 (elastic deformation function and elastic return deformation function) is as described above.

  First, the holding plate 8 is formed in the shape of a fishing hook in cross section, and its base end portion 8a is fixed to the upper and lower wall surfaces 3b and 3b of the movable core 3 or the upper and lower inner wall surfaces 2b and 2b of the troyoke 2 via the fixing means 9, respectively. On the other hand, the hook-shaped tip 8 a is in contact with the upper and lower inner wall surfaces 2 b and 2 b of the troyoke 2 or the upper and lower wall surfaces 3 b and 3 b of the movable core 3. In this embodiment, the holding plate 8 is fixed to the upper and lower wall surfaces 3b, 3b of the movable core 3 as an example of the fixing portion, but of course, the holding plate 8 is fixed by means of fixing (fixing, engagement, welding, etc.). The upper and lower inner wall surfaces 2b and 2b may be fixed to a line object.

  Next, it is sufficient for the holding plate 8 to have at least an elastic deformation function. However, the holding plate 8 of this embodiment has a rigid function that can withstand the weight of the movable core and does not deform in a normal state. As shown in FIG. 1, the movable core is held in the upper and lower gaps 46, 46 in a well-balanced manner, and is formed on the cross-section fishhook with a resilient material. At the moment when there is no more, there is an elastic return deformation function that immediately secures the original holding state by the elastic return force of the material itself.

  Therefore, the shape of the holding plate 8 is desirably limited to the shape of the embodiment as long as it has (a) a rigid function, (b) an elastic deformation function, and (c) an elastic return deformation function. Absent.

  Next, in the upper and lower portions of the left and right side walls 15c and 15c of the troyoke 2, a total of four base plate-shaped notch portions 20 and 20 for the left and right baseballs are formed respectively. Depending on the case, the shape may be changed as appropriate, and the number may be increased or decreased.

  Furthermore, in the central part of the left and right side walls 3c, 3c of the movable core, one receiving piece for the locking piece that can come into contact with the lower surface of the locking piece at the time of the earthquake is fixedly placed horizontally. Another receiving piece may be provided laterally so as to be in contact with the upper surface of the locking piece. The shape of the receiving piece for the locking piece can be arbitrarily changed in design. Further, for example, it is also equivalent that the engaged portions 22 are formed on the left and right side walls of the movable core, and the engaging portions 30 that are temporarily engaged with the engaged portions 22 are provided on the left and right side walls of the troyoke. is there.

  In addition, the main part of the present invention may be applied to a door lock bracket including the reinforcing frame described in Patent Document 2.

  Next, a second embodiment shown in FIGS. 9 to 11 will be described. In the description of the second embodiment, the same parts as those in the first embodiment are denoted by the same or similar reference numerals, and redundant description is omitted.

  In the second embodiment, the main difference from the above-described embodiment is that the design of the formation object of the holding pin notch and the insertion hole is changed. That is, as shown in FIG. 10, the insertion holes 28A and 28A for the holding pins 21 and 21 are formed vertically on the left and right side walls 15c and 15c, respectively, while the left and right side walls 3c and 15c of the movable core 3A are formed. In 3c, the holding pin relief notches 20A and 20A are formed vertically. The engaging relationship between the upper and lower holding pins 21 and 21 and the upper and lower notches 20A and 20A in this embodiment is as shown in FIG. Since the shape, attachment location, action, and the like of the holding plate 8A are the same as those in the first embodiment, a duplicate description is omitted.

  Comparing FIG. 9 with FIG. 1 of the first embodiment, the directions of the notches 20A and 20A are reversed, and when the strike fixtures 40 and 40 are screwed, the upper and lower holding pins 21 and 21 are The small engagement grooves 20a and 20a located on the rear gap 45 side in the troyoke 2A are respectively engaged. Even if the design is changed in this way, the same operation and effect as the first embodiment can be obtained.
