  In the joinery of Patent Document 1, it is difficult to cause a shift in the contact between the sub-block and the inner impingement, and it is possible to perform reliable release control by the sub-block. By applying a large force, as shown in FIGS. 6 (a) and 6 (b), the sub-lock is locked into the lower hook from the mounting hole of the lower hook to which the sub-lock is fixed. There was a possibility that the restriction of opening of the shoji could be released due to the housed state.

  The present invention has been made in view of the above circumstances, and when a large external force is applied in the direction of opening the shoji in a state where the opening of the shoji is restricted by the sub-lock, the sub-block is placed inside the shoji by the external force. It is an object of the present invention to provide a joinery that can prevent the disengagement of the shoji opening restriction by being immersed in the door and maintain the restricting state of the shoji opening by the sub-block.

  The invention according to claim 1 of the present application is a frame that is fixed to the frame opening, a shoji that is slidably opened and closed with respect to the frame, and an indoor side surface of the shoji's coffin that opens the shoji. The saddle has a sub-block to be regulated, and the inner side surface where the sub-block is disposed is formed of a resin material, and the attachment portion for attaching the sub-block is formed on the inner side surface where the sub-block is disposed. Consists of a case member attached to the saddle of the shoji, a locking member that is supported by the case member and restricts the opening of the shoji and a storage state that does not interfere with the opening of the shoji, and attaches the sub-block. For the door end side of the mounting part or the door end side of the sub block, when the locking member of the sub block protrudes, a force in the opening direction is applied to the shoji and the sub block is moved to the door side of the mounting part. strength When pressed, characterized in that it has a dehiscent introduction portion for guiding the opening rip door end sides of the mounting portion.

  According to the present invention, even when a large external force is applied in the direction of opening the shoji in a state where the opening of the shoji is restricted by the sub-block, the sub-block is restricted without being submerged into the shoji of the shoji. The state can be maintained.

A joinery according to an embodiment of the present invention is installed in a building opening of a building, and as shown in FIGS. 1 (a) and 1 (b), a frame formed by assembling an upper frame, a lower frame, and a left and right vertical frame on four sides. The body 1 and the upper and lower heels and the left and right vertical ridges are assembled on the four circumferences, and the panel body is fitted on the inner circumference. On the other hand, it is configured as a sliding sash that opens and closes the housing opening by supporting the outer shoji 2, 3 along the outer guide rail so as to be movable in the left-right direction.
The crescent lock 4 is arranged at the summing part of the inner and outer shoji 2, 3 and the inner side of the lower arm 32 of the outer shoji 3 near the summit 23 is placed on the inner, outer shoji 2, 3 A sub-block 5 for restricting the opening of the inner impeller 2 is disposed, and a bracing member 6 for preventing the inner impeller 2 from swinging with respect to the inner guide rail 12a is disposed at the lower end of the summing cage 23 of the inner impeller 2. .
In addition, the joinery of the present invention is not limited to the sliding sash, and can be opened or closed by sliding a shoji with respect to the window frame, such as a single sliding window. A sash may be used.

  As shown in FIGS. 2A and 2B, the sub-lock 5 has a case member 51 that is locked and fixed to the inner side surface of the lower arm 32 of the outer shoji 3, and a support shaft 51 a centered on the case member 51. Thus, the lock member 52 is rotatably held.

As shown in FIGS. 2C and 2D, the case member 51 has a rectangular frame-shaped frame portion 511 that holds the lock member 52. On the periphery of the one-side opening of the frame-shaped portion 511, When the case member 51 is locked and fixed to the attachment hole formed on the indoor side surface of the lower rod 32, the case member 51 has flange portions 512 arranged on the periphery of the attachment hole. Engagement pieces 513 and 514 that are engaged with the indoor side wall of the lower rod 32 or the indoor side wall of the summit rod 23 when protruding and fixed in the mounting hole protrude.
In addition, an engagement elastic piece 511a having elasticity extends from the substantially center position of the other side opening toward the door end side (closing direction) of the shoji 3 at the other side opening of the frame-like portion 511. And a holding piece portion that engages and holds the positioning portion 521b on the opposite side of the lock member 52 when the lock member 52 is in a projecting state at the door end side portion (near the closing direction end portion position of the other side opening). 511b.
Further, the lock position and the storage position of the lock member 52 that rotates with respect to the frame-like portion 511 are positioned near the opening on one side on the summing side of the frame-like portion 511 (on the side of the opening of the shoji). Positioning projections 511c and 511c to be projected are provided.

The lock member 52 is selectively supported between a protruding state that protrudes from the case member 51 and restricts the opening of the shoji and a storage state that is housed in the case member 51 and does not interfere with the opening of the shoji. As shown in FIGS. 2 (e) and 2 (f), the lock member 52 has a lock projection 521a formed at one end of a block-shaped lock body 521 and a positioning portion 521b formed at the other end. Near the other end of the main body 521, a shaft hole 521c for rotatably supporting the lock member 52 with respect to the case member 51 is formed.
Further, a positioning recess 521d is formed near the lock projection 521a of the lock body 521 so as to contact the positioning protrusions 511c and 511c of the case member 51 at the lock position and the storage position of the lock member 52.

On the other hand, a resin lower collar 322 formed of a resin material is disposed on the indoor side of the lower collar 32 of the outer cover 3 to which the sublock 5 is attached, and the attachment portion of the sublock 5 is illustrated in FIG. As shown in the figure, it is formed as a mounting hole 322 a provided at the end of the summit side of the interior side of the resin lower end 322 of the lower end 32. It is formed so that the summit side of the attachment hole 322a is covered with the indoor side front wall 341 of the summit bowl 34 when it is abutted and connected.
When attaching the sub-lock 5 to the lower rod 32, the case member 51 is inserted into the attachment hole 322a from the summoning side toward the door-end side, and the door-end-edge side end portion of the attachment hole 322a is attached to the flange portion. 512 and the engagement piece 513 are sandwiched and locked, and the lower rod 32 is summed up in a state where the entire sub-lock 5 is fitted into the attachment hole 322a and the flange portion 512 is brought into contact with the outer periphery of the attachment hole 322a. 34, the engaging piece 514 is restrained by the indoor-side front wall 341, and the sub-lock 5 is attached to the summit side of the lower arm 32 of the external shoji 3.

  The bracing member 6 attached to the lower end of the summon 23 of the inner shoji 2 is made of, for example, a resin material, and is inserted into the hollow portion of the summon 23 from below as shown in FIGS. 4 (a) and 4 (b). On the outer peripheral surface of the summing rod 23, the steadying portion 62 formed at the lower end portion of the insertion mounting portion 61 and disposed so as to be sandwiched with a gap with respect to the inner guide rail 12a. It has an inner peripheral wall portion 63 to be disposed, and when an external force such as wind is applied, the steadying portion 62 comes into contact with the inner guide rail 12a, so that the shoji can be shaken more greatly and become loose. It prevents it from coming off.

  And the locking member 52 in the state which made the locking member 52 of the sub-lock 5 arrange | positioned at the outdoor outer side part of the inner peripheral wall part 63 of the bracing member 6 the lower armpit 32 of the outer shuffler 3 into a locked position. A concave portion 63a that opens upward is formed at a position where the lock convex portion 521a faces, and further, on the indoor side of the concave portion 63a, the inner surface of the lock convex portion 521a that abuts on the concave portion 63a abuts. Thus, a detachment projection 63b is formed to prevent the lock projection 521a from coming out indoors.

(Opening control by sub-lock)
When the opening of the inner and outer obstacles 2, 3 is restricted by the sub-lock 5, the lock member 52 of the sub-lock 5 is attached to the support shaft 51 a of the case member 51, as shown in FIGS. 5 (a) and 5 (b). The lock convex portion 521a of the lock member 52 is protruded from the lower rod 32 to the indoor side by rotating to the protruding position around the center. As a result, when the inner shoji 2 is opened, the outer peripheral surface of the summing cage 23 of the inner shoji 2 abuts against the lock convex portion 521a, thereby preventing further opening movement. Is restricted.

  At this time, the bracing member 6 is disposed at the lower end of the summing cage 23 of the inner limb 2 with which the lock convex portion 521a abuts, and the lock convex portion 521a is formed on the inner peripheral wall portion 63 of the choke member 6. By engaging and abutting against the concave portion 63a, for example, even if an intruder tries to pry the inner and outer obstacles 2 and 3 by a bar or the like, the lock convex portion 521a is prevented from coming off in the indoor / outdoor direction, and the sub-lock 5 Therefore, it is possible to prevent the external shoji 2 and 3 from being opened. The force to pry the inner and outer shoji 2, 3 is received by the inner peripheral wall 63 of the anti-vibration member 6, but the force received by the inner peripheral wall 63 of the anti-vibration member 6 is the anti-rest portion. Since it is transmitted to 62 and can be received by the inner guide rail 12a, the locked state by the sub-lock 5 can be maintained.

  However, at the time of prying the sliding joinery with a bar or the like, by using the lever principle, it is possible to generate a very strong prying force enough to destroy the resin shape. And since the engagement state of the lock convex part 521a of the sub block 5 and the concave part 63a of the inner peripheral wall part 63 of the anti-vibration member 6 is strong, as shown in FIGS. 6 (a) and 6 (b), When the door side of the sub-block 5 is strongly pressed against the door side of the mounting hole 322a and the corner of the mounting hole 322a is cracked, the indoor side of the door side is turned up. The lower cover 32 of the outer shoji 3 may get stuck in the hollow interior of the lower resin cover 322. If the sub-lock 5 is sunk into the resin lower collar 322 of the lower collar 32 in this way, the protruding state of the lock member 52 is not maintained and the storage state is changed, and the locked state by the lock member 52 cannot be maintained. The inner and outer shoji 2, 3 may be opened.

Therefore, in the joinery of the present invention, the sub-lock 5 is strongly attached to the attachment hole 322a in the attachment portion (attachment hole 322a) of the lower collar 32 or the case member 51 of the sub-block 5 for attaching and fixing the sub-lock 5. When the resin lower rod 322 on the door end side of the mounting hole 322a is turned up when it is pressed, the resin block 322 on the door tip side of the mounting hole 322a is torn open, so that the sub-lock 5 is the resin of the lower rod 32. A cleaving introduction portion is formed to prevent intrusion into the lower rod 322.
Specifically, in the joinery of the present embodiment, as shown in FIG. 3A, the door part side of the attachment part (attachment hole 322 a) of the sub-block 5 of the lower heel 32 of the shoji 3 is split. An open introduction recess 322b is formed.

  By providing a tear-introducing recess 322b in the mounting portion (mounting hole 322a), when a strong prying force due to a bar or the like is generated in the outer shoji 2, 3, the recess of the bracing member 6 of the inner shoji 2 The locking member 52 of the sub-block 5 that is abutted and fixed to 63a receives a force toward the door end side. However, a cleaving introduction recess 322b is formed on the door end side of the attachment portion (attachment hole 322a). As a result, the resin lower rod 322 of the lower collar 32 is cleaved starting from the cleavage introduction recess 322b, and the sub-lock 5 is placed under the resin of the lower collar 32 as shown in FIGS. 7 (a) and 7 (b). Since it moves to the door-end side without being sunk into the heel 322, it is possible to maintain a state in which the lower heel 32 protrudes to the indoor side surface.

  Even if a strong pry-off force is generated by prying off with a bar or the like, the locked state by the sub-lock 5 cannot be released, and the shoji is not fully opened.

As described above, in the present embodiment, the lock convex portion 521a is formed at the distal end portion of the lock member 52 of the sub-block 5 disposed on the inner side surface of the lower arm of the external shoji, and the lock convex portion 521a is the inner impeller 2. Since the opening of the inner and outer shoji is restricted by engaging with the recess 63a formed in the inner peripheral wall 63 of the bracing member 6 disposed at the lower end of the summoning bowl 23, even if it is attempted to pry it open with a bar or the like, The lock member 52 does not come off in the indoor / outdoor direction.
Further, since the force related to the lock member 52 is received by the anti-vibration member 6 by prying with a bar or the like, and can be received by the inner guide rail 12a via the anti-vibration portion 62 of the anti-vibration member 6, a strong regulated state is maintained. can do.

Further, when a stronger prying force is applied by prying with a bar or the like, a tear introduction recess 322b is formed on the door side of the mounting hole 322a for mounting and fixing the sub-lock 5, and the mounting hole Since the door end side of 322a is torn open, the sub-lock 5 is prevented from being recessed into the hollow interior of the lower arm and the lock member 52 being brought into the accommodated state, and the opening restriction state by the sub-block is prevented. It can be further maintained.
In addition, although the cleaving introduction part in this embodiment is formed by the cleaving introduction recessed part provided in the attachment hole, it is good also as a thin-walled part, and the door of the attachment hole of a lower arm is pushed by pressing a sub-block. The shape and the like are not particularly limited as long as the lower side resin underarm can be opened and moved.

(Other embodiments)
In the shoji of the previous embodiment, the dehiscence introduction portion is formed as a dehiscence introduction recess 322b provided in the attachment portion (attachment hole 322a) of the lower collar 32 of the outer shoji 3. However, the present invention is not limited to this. In addition, a split introduction convex portion 511d may be provided on the door end side portion of the case member 51 of the sub-block 5.
Specifically, as shown in FIGS. 8 (a) and 8 (b), the tear-introducing convex portion 511d has a triangular shape at a portion between the flange portion 512 on the door side surface of the case member 51 and the engaging piece 513. It is formed as a protruding protrusion.
On the other hand, as shown in FIG. 8 (c), a housing recess 322c is formed on the side of the door tip of the mounting hole 322a of the lower collar 32, and as shown in FIG. In a state of being attached to the attachment hole 322a, the cleavage introduction convex portion 511d of the sub-lock 5 is arranged in the storage concave portion 322c of the attachment hole 322a.

  In this way, by providing the split-introducing convex portion 511d on the side of the door tip of the sub-lock 5, the sub-block 5 is strongly pressed against the side of the door tip of the mounting hole 322a of the lower rod 32 by a strong prying force by a bar or the like. When the door side on the upper and lower sides of the storage recess 322c of the mounting hole 322a is deformed, the cleavage introduction convex part 511d of the sub-lock 5 is placed on the door side of the storage recess 322c of the mounting hole 322a of the lower rod 32. Since the sub-lock 5 is moved to the door end side without being recessed into the resin lower collar 322 of the lower collar 32, the state of protruding to the indoor side surface of the lower collar 32 can be maintained. .

In addition, although the cleaving introduction part in this embodiment is formed by the cleaving introduction convex part provided in the door end side part of the sublock, the door end of the attachment hole of the lower rod is pressed by the sublock. The shape or the like is not limited as long as it can be opened and moved on the side resin lower arm.
In the present embodiment, the sliding shoji is adopted as the shoji, but a single shoji shoji in which the indoor shoji is fixed may be used.
Further, the recumbent can be an upper reed, a lower reed, or another recumbent. Further, a composite brazing material in which the indoor side is formed of a resin member and the outdoor side is formed of an aluminum member may be used, or a resin brazing material may be formed of the resin member as a whole. It is only necessary that the indoor portion where the is disposed is formed of a resin member.
