Description

  The present invention relates to a lock receiving guide provided at the door of a shoji and a fitting including the lock receiving guide.

  BACKGROUND ART Joiners such as sliding windows have been provided with a locking device called a door lock. The locking device is constituted by, for example, a locking mechanism disposed on a vertical shaft located at a door tip in a shoji, and a lock holder disposed on a vertical frame facing the vertical shaft of the door tip in an opening frame. . In this locking device, when the shoji is closed, the lock receiver enters the inside of the vertical fence through a pull-in opening formed in the wall of the vertical fence, and the lock receiver that has entered eventually engages the locking mechanism. As a result, the vertical frame and the vertical rod are prevented from moving apart from each other, and the shoji is kept closed with respect to the opening frame. If the engagement state between the lock receiver and the locking device is released, the shoji can be opened (see, for example, Patent Document 1).

While allowing the rotation, the locking portion 322 is locked to the hook base 311 when the engagement hook 310 is moved to the locking position, and functions to prevent rotation toward the unlocking position. The ratchet 320 is linked to a release lever (not shown). A release lever (not shown) separates the ratchet 320 from the engagement hook 310 when operated from the outside of the door toe 23 and allows the engagement hook 310 in the locked position to rotate to the unlocked position. To do.

  Furthermore, a lock receiving guide 40 is attached to the door rod 23 of the shoji 20 in the joinery. As shown in FIGS. 1 to 4, the lock receiving guide 40 includes a guide main body 41 having a guide hole 41 a in the center and a pair of support receiving portions 42 protruding from both ends of the guide main body 41. The guide body 41 is inserted into the pull-in opening 32 in a state where a part thereof is exposed to the outside, and the support receiving portions 42 are respectively inserted into the insertion holes 33, thereby It is detachably attached to the door wall 23a. More specifically, the lock receiving guide 40 has locking projections 41b and 41c at portions corresponding to the cover pieces 23e and 23f in the guide main body 41, and covers these locking projections 41b and 41c. By elastically engaging the engagement fins 23i and 23j of the pieces 23e and 23f, the pieces 23e and 23f are detachably attached to the door-end wall 23a.

  A receiving surface 41d is formed in a portion of the guide body 41 facing the ridge 13a of the vertical frame 13. The receiving surface 41d is a flat portion formed so as to be parallel to the contact surface 13b of the protrusion 13a, and is formed at a position where a sufficient thickness is secured from the door-end surface 23g of the door-end rod 23. is there. The position of the receiving surface 41d is such that the hook portion 312 of the engaging hook 310 is engaged with the engaging hole 31a of the lock receiving member 31 that has entered the retraction opening 32 when the contact surface 13b of the protrusion 13a contacts. The hook portion 312 of the engagement hook 310 is set so as to be in contact with the engagement surface 31b of the engagement hole 31a. As shown in FIG. 1B, when the protrusion 13a of the vertical frame 13 comes into contact with the receiving surface 41d, the tips of the cover pieces 23e and 23f and the prospective surface of the vertical frame 13 are in direct contact. A gap is secured to prevent this.

  As shown in FIG. 4, each of the support receiving portions 42 has a columnar shape that protrudes from a portion that is an extension of a portion of the receiving surface 41 d of the guide main body 41 against which the protrusion 13 a abuts. In the mounted state, the individual tip surfaces are in contact with the support wall 23b.

  In addition, a recess 41f is provided on the mounting surface 41e of the guide body 41 that faces the door end surface 23g. The recess 41f is a recess formed in a portion of the door-end wall 23a that becomes the outer peripheral edge of the pull-in opening 32. When the lock receiving guide 40 is mounted on the door-end ridge 23, the guide main body 41 and the door-end wall It is avoided that the cutting edge of 23a contacts each other.

  In the joinery configured as described above, when the shoji 20 is in an open state with respect to the opening frame 10, as shown in FIG. 1A and FIG. 2A, the engagement hook of the locking mechanism 300. 310 is arranged at an unlocking position by an unlocking spring (not shown). The lock receiving guide 40 provided on the door-end surface 23g of the shoji 20 is accommodated in the accommodating portion 23H formed on the door-end fence 23, and most of the cover is covered with the cover pieces 23e, 23f. It is not easily seen from the outside, and the appearance quality is not significantly impaired.

  When the shoji 20 is closed from this state, as shown in FIGS. 1 (b) and 2 (b), the lock 31 provided on the vertical frame 13 enters the interior of the door-toe 23 through the opening 32 for retraction. When the protrusion 13a of the vertical frame 13 comes into contact with the receiving surface 41d of the guide body 41, the hook portion 312 of the engaging hook 310 enters the engaging hole 31a of the lock receiver 31 and contacts the engaging surface 31b. At the same time, the locking portion 322 of the ratchet 320 is locked to the hook base portion 311 and the rotation of the engagement hook 310 to the unlocked position is prevented.

  In this state, the engagement hook 310 of the locking mechanism 300 and the lock receiver 31 of the vertical frame 13 are engaged to prevent the vertical frame 13 and the door-end rod 23 from moving apart from each other. On the other hand, the shoji 20 is kept closed. Moreover, since the engaging hook 310 contacts the engaging surface 31 b of the lock receiver 31 when the protrusion 13 a of the vertical frame 13 contacts the receiving surface 41 d of the lock receiving guide 40, the shoji 20 is applied to the opening frame 10. The movement is prevented not only in the direction of opening the door but also in the direction of closing the shoji 20. Therefore, there is no possibility of causing a situation in which the shoji 20 is loose in the locked state.

  On the other hand, when a release lever (not shown) (not shown) is operated from this state, the locking portion 322 of the ratchet 320 is separated from the hook base 311 and the engagement hook 310 is moved by the spring force of the unlocking spring (not shown). Accordingly, the hook portion 312 of the engagement hook 310 is deviated from the engagement hole 31a of the lock receiving guide 40, and the shoji 20 can be opened with respect to the opening frame 10.

  Here, when the shoji 20 is closed with respect to the opening frame 10, the ridge 13 a of the vertical frame 13 comes into contact with the receiving surface 41 d of the lock receiving guide 40 provided on the door rod 23. An impact force may be applied to the guide body 41 of the receiving guide 40. However, according to the joinery described above, the support receiving portion 42 is provided in the guide main body 41 of the lock receiving guide 40, and the front end surface thereof is brought into contact with the support wall 23 b of the door toe 23. Therefore, when the ridge 13a comes into contact with the guide body 41, an external force acting on the guide body 41 and the door wall 23a can be transmitted to the support wall 23b via the support receiving portion 42 of the guide body 41. There is no fear that a large impact force is applied to the door-end wall 23a on which the lock receiving guide 40 is mounted. The support wall 23b of the door toe wall 23 is not formed with the pull-in opening 32 like the door toe wall 23a, and it is possible to ensure sufficient rigidity without securing a large thickness. This eliminates the possibility of damaging the door wall 23a without increasing the wall thickness of the door wall 23a. It becomes possible to lock between 20 and the opening frame 10.

  In the above-described embodiment, the guide main body 41 and the support receiving portion 42 are integrally formed. Therefore, the number of parts when handling is not increased, but the guide main body 41 and the support receiving portion 42 are separated. It may be formed into a body. Further, as shown in FIG. 4, the support receiving portion 42 is in contact with the support wall 23 b in a state in which each tip end surface is attached to the door toe 23. For example, the support receiving portion 42 is supported in a state in which the shoji 20 is open. The individual tip surfaces of the receiving portion 42 may be separated from the support wall 23b, and the individual tip surfaces of the support receiving portion 42 may abut against the support wall 23b when the shoji 20 is closed.

  Furthermore, in embodiment mentioned above, in the state in which the lock receiving guide 40 was attached to the door-end wall 23a, what the surface facing the door-end wall 23a of the guide main body 41 and the door-end wall 23a contacted is illustrated. However, this invention is not limited to this, For example, you may provide even if the surface facing the door-end wall 23a of the guide main body 41 and the door-end wall 23a are spaced apart. In this case, the lock receiving guide 40 is mounted on the door-end wall 23a so that the locking protrusions 41b and 41c of the guide body 41 are elastically engaged with the engagement fins 23i and 23j of the cover pieces 23e and 23f. Can do. In this state, when the protrusion 13a of the opening frame 10 comes into contact with the guide body 41, an external force acts only on the guide body 41, and this external force acts on the support wall 23b via the support receiving portion 42. Become. For this reason, the external force which acted on the guide main body 41 is not applied to the door-end wall 23a of the door-end fence 23, and there is no possibility that the door-end wall 23a will be deformed.

  In the above-described embodiment, the support wall 23b is exemplified as one that constitutes the outer surface of the ridge. For example, if an inner wall corresponding to the support wall 23b exists in the heel, the inner wall Can also be configured as a support wall.

  Furthermore, in embodiment mentioned above, although what has provided a locking device between the vertical frame 13 and the vertical rod 23 is illustrated, this invention is not limited to this. For example, when applied to a joinery in which the shoji 20 slides up and down with respect to the opening frame 10, a locking device is provided between the lower frame 12 and the lower rod 22 or between the upper frame 11 and the upper rod 21. Is also possible.
