There is a well-known fitting that is provided with a sublock 5 that protrudes to the inside of the room during locking and interferes with the assembling frame of the inner shoji to restrict the opening of the shoji.
In such a fitting, a protrusion is formed at a portion of the sublock that interferes with the summing frame of the shob, and a groove is formed in the summing frame to which the protrusion abuts. There is known a fitting that includes a sublock that prevents the sliding door from being dislocated from the mating frame and ensures the restriction of the opening of the shoji by the sublock. (Patent Document 1)

: JP2005-139849A

In the fitting of Patent Document 1, the contact between the sublock and the internal shoji is less likely to be displaced, and the reliable opening of the sublock can be regulated. By applying a large force, as shown in FIGS. 6(a) and 6(b), the lock block of the sub block is pushed into the lower frame from the mounting hole of the lower frame where the sub block is fixed. There was a possibility that it would be stored in the body and the restrictions on opening the shoji screen would be lifted.

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 while the opening of the shoji is restricted by the sublock, the sublock causes the sublock to move within the frame of the shoji. It is an object of the present invention to provide a fitting that can prevent the restriction of opening the shoji screen from being released due to being immersed in the door and can maintain the restricted state of opening the shoji screen by the sublock.

The invention according to claim 1 of the present application is a frame body fixed to a frame opening, a shoji slidingly arranged with respect to the frame and an indoor side surface of a frame of the shoji to open the shoji. The frame has a restricting sub-block, and the inside of the frame on which the sub-block is arranged is formed of a resin material, and an attaching portion for attaching the sub-block is formed on the inner side of the sub-block. Consists of a case member attached to the frame of the shoji screen, a lock member that is supported by the case member, and can be selected from a protruding state that regulates the opening of the shoji screen and a storage state that does not interfere with the opening of the shoji screen. For the door tip side of the attachment part, or the door tip side of the sublock, when the lock member of the sublock is in a protruding state, a force in the opening direction is applied to the shoji and the sublock is attached to the door tip side of the attachment part. It is characterized by having a cleaving introduction part that guides cleaving the door edge side of the mounting part when it is strongly pressed.

ADVANTAGE OF THE INVENTION According to this invention, even if a large external force is applied in the direction which opens a shoji while restricting the opening of the shoji by the sublock, the sublock does not sink into the frame of the shoji and the opening of the shoji is regulated. The state can be maintained.

As shown in FIGS. 2( a) and 2 (b ), the sub block 5 has a case member 51 fixed to the inner side surface of the lower frame 32 of the outer shoji 3 and a support shaft 51 a with respect to the case member 51. The lock member 52 is rotatably held.

As shown in FIGS. 2C and 2D, the case member 51 has a rectangular frame-shaped frame-shaped portion 511 that holds the lock member 52, and the frame-shaped portion 511 has a peripheral edge of one opening. When the case member 51 is locked and fixed to the mounting hole formed on the inner surface of the lower frame 32, the case member 51 has flange portions 512 arranged on the periphery of the mounting hole. Engaging pieces 513 and 514 that are engaged with the inner side wall of the lower frame 32 or the front side wall of the interior of the summing frame 23 when locked and fixed in the mounting hole are projected.
Further, in the other opening of the frame-shaped portion 511, an engaging elastic piece 511a having elasticity is provided to extend from the substantially central position of the other opening toward the door end side (closing direction) of the shoji screen 3. In the door tip side portion (near the position of the closing direction end portion of the opening on the other side), a holding piece portion in which the positioning portion 521b on the opposite projecting side of the lock member 52 is engaged and held in the projecting state of the lock member 52. 511b is provided.
Further, the lock position and the storage position of the lock member 52 that rotates with respect to the frame-shaped part 511 are positioned near the one side opening on the assembly side (outer shoji opening direction side) of the frame-shaped part 511. Positioning protrusions 511c and 511c are provided so as to project.

The lock member 52 is selectively supported in a protruding state in which it projects from the case member 51 to restrict the opening of the shoji screen, and in a stored state in which it is housed in the case member 51 and does not interfere with the opening of the shoji screen. As shown in FIGS. 2(e) and 2(f), the lock member 52 has a lock protrusion 521a formed at one end of a block-shaped lock body 521 and a positioning portion 521b formed at the other end. A shaft hole 521c for rotatably supporting the lock member 52 with respect to the case member 51 is formed near the other end of the main body 521.
Further, a positioning recess 521d that abuts the positioning protrusions 511c and 511c of the case member 51 at the lock position and the storage position of the lock member 52 is formed near the lock protrusion 521a of the lock body 521.

On the other hand, a resin lower frame 322 made of a resin material is arranged on the indoor side of the lower frame 32 of the shoji 3 to which the subblock 5 is mounted, and the mounting portion of the subblock 5 is shown in FIG. As shown, the resin lower frame 322 of the lower frame 32 is formed as a mounting hole 322a provided at the end of the interior side of the interior side of the resin lower frame 322. The connecting frame side of the mounting hole 322a is formed so as to be covered by the indoor side front wall 341 of the combining frame 34 when they are butted and connected.
When the sub block 5 is attached to the lower frame 32, the case member 51 is inserted into the attachment hole 322a from the assembly side toward the door tip side so that the end portion of the attachment hole 322a on the door tip frame side is a collar portion. The lower frame 32 is sandwiched by the 512 and the engagement piece 513 and locked, and the lower frame 32 is assembled in a state where the entire sub block 5 is fitted into the mounting hole 322a and the collar portion 512 is brought into contact with the outer periphery of the mounting hole 322a. By inserting the engaging piece 514 into the front side wall 341 of the indoor side, the sub block 5 is attached to the lower frame 32 side of the lower frame 32 of the outer shoji 3 by being inserted into the front frame of the outer frame 34.

The anti-vibration member 6 attached to the lower end of the fitting frame 23 of the inner shoji 2 is made of, for example, a resin material or the like, and is inserted from below into the hollow portion of the fitting frame 23 as shown in FIGS. On the outer peripheral surface of the fitting frame 23, and a steady rest 62 formed on the lower end portion of the insert mounting portion 61 so as to sandwich the inner guide rail 12a with a gap therebetween. It has an inner peripheral wall portion 63 to be arranged, and when the steady rest 62 comes into contact with the inner guide rail 12a when an external force such as wind is applied, the shoji swings further and rattles, It prevents it from coming off.

Then, the lock member 52 with the lock member 52 of the sub block 5 arranged on the upper side of the outdoor side of the inner peripheral wall portion 63 of the anti-vibration member 6, specifically, the lower frame 32 of the outer shoji 3 in the lock position. A concave portion 63a having an upper opening is formed at a position where the lock convex portion 521a of the lock convex portion 521a faces the interior side surface of the lock convex portion 521a abutting the concave portion 63a. As a result, the disengagement preventing protrusion 63b is formed to prevent the lock protrusion 521a from being disengaged toward the indoor side.

(Open restrictions by subrock)
When restricting the opening of the inner and outer shoji blocks 2 and 3 by the sub block 5, as shown in FIGS. 5(a) and 5(b), the lock member 52 of the sub block 5 is attached to the support shaft 51a of the case member 51. The lock convex portion 521a of the lock member 52 is caused to protrude from the lower frame 32 toward the indoor side by rotating the lock convex portion 521a to the protruding position. Thereby, when the inner shoji 2 is opened, the outer peripheral surface of the summing frame 23 of the inner shoji 2 comes into contact with the lock convex portion 521a to prevent further opening movement, so that the inner and outer shoji 2, 3 Opening is regulated.

At this time, the anti-vibration member 6 is arranged at the lower end of the summing frame 23 of the inner shoji 2 with which the locking convex part 521 a abuts, and the locking convex part 521 a is formed on the inner peripheral wall part 63 of the anti-vibration member 6. By engaging and abutting the concave portion 63a, for example, even if an intruder tries to pry open the inner and outer sliding doors 2 and 3 with a crowbar or the like, the lock convex portion 521a is prevented from coming off in the indoor/outdoor direction, and the sub lock 5 is prevented. It is possible to prevent the inner and outer shoji 2 and 3 from opening. Then, the force of opening the inner and outer shoji 2, 3 is received by the inner peripheral wall portion 63 of the anti-vibration member 6, but the force received by the inner peripheral wall portion 63 of the anti-vibration member 6 is the steady rest portion. Since it is transmitted to 62 and can be received by the inner guide rail 12a, a strong locked state by the sub block 5 can be maintained.

However, when prying open 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 profile. Further, since the lock convex portion 521a of the sub block 5 and the concave portion 63a of the inner peripheral wall portion 63 of the anti-vibration member 6 are firmly engaged with each other, as shown in FIGS. 6(a) and 6(b), The side surface of the door block of the sub block 5 is strongly pressed against the side of the door hole of the mounting hole 322a, and a crack is formed at a corner of the mounting hole 322a, so that the indoor side surface of the door end side is turned up. The lower frame 32 of the outer shoji 3 may get caught in the hollow inside of the resin lower frame 322. In this way, if the sub block 5 slips into the resin lower frame 322 of the lower frame 32, the protruding state of the lock member 52 is not maintained and the lock state is changed to the housed state, so that the locked state by the lock member 52 cannot be maintained. The inner and outer shoji screens 2 and 3 may be opened.

Therefore, in the fitting of the present invention, the mounting portion (mounting hole 322a) of the lower frame 32 for mounting and fixing the sub block 5 or the case member 51 of the sub block 5 and the sub block 5 strongly to the mounting hole 322a. Before the resin lower frame 322 on the door end side of the mounting hole 322a is turned up when pressed, the resin lower frame 322 on the door end side of the mounting hole 322a is torn open so that the sub block 5 is made of 32 resin of the lower frame. A tear-introducing portion is formed to prevent the lower frame 322 from slipping into the lower frame 322.
Specifically, in the fitting of the present embodiment, as shown in FIG. 3( a ), the door frame frame side of the mounting portion (mounting hole 322 a) of the sub block 5 of the lower frame 32 of the shoji screen 3 is torn. 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 burl or the like is generated in the inner and outer shovels 2 and 3, the recess of the vibration damping member 6 of the inner shoji 2 is formed. The lock member 52 of the sub block 5 that is abutted and fixed to the 63a receives a force directed toward the door end side, but the cleaving introduction concave portion 322b is formed on the door end side of the attachment portion (attachment hole 322a). By this, the resin lower frame 322 of the lower frame 32 is torn open from the cleaving introduction recess 322b as a starting point, and the sub block 5 is placed under the resin of the lower frame 32 as shown in FIGS. 7(a) and 7(b). Since it moves to the door end side without being inserted into the frame 322, it is possible to maintain the state in which the lower frame 32 projects to the inner surface of the room.

Even if a strong prying force is generated by prying with a burl or the like, the locked state by the sublock 5 cannot be released and the shoji does not fully open.

As described above, in the present embodiment, the lock convex portion 521a is formed at the tip of the lock member 52 of the sub block 5 arranged on the indoor side surface of the lower frame of the external shoji, and the lock convex portion 521a forms the inner shoji 2. Since the opening of the inner and outer shoji is restricted by engaging with the recessed portion 63a formed in the inner peripheral wall portion 63 of the vibration isolating member 6 arranged at the lower end of the summing frame 23, even if it is tried to pry open with a bar or the like, The lock member 52 does not come off in the indoor/outdoor direction.
Further, since the force of the lock member 52 can be received by the anti-vibration member 6 by the prying opening by a burl 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 regulation state is maintained. can do.

Further, when a stronger prying force is applied by prying with a burl or the like, a cleaving introduction concave portion 322b is formed in the door edge side of the mounting hole 322a for mounting and fixing the sub block 5, Since the door edge side of 322a is guided to be torn open, it is prevented that the lock block 52 is set in the hollow inside of the lower frame and the lock member 52 is in the housed state, and the open regulation state by the lock block is prevented. It can be maintained even further.
Although the dehiscence introducing portion in the present embodiment is formed by the dehiscence introducing concave portion provided in the mounting hole, it may be a thin wall portion or the door of the lower frame mounting hole by pressing the sublock. The shape and the like are not limited as long as the resin lower frame on the front side can be torn open and moved.

(Other embodiments)
In the shoji of the previous embodiment, the dehiscence introducing portion is formed as the dehiscence introducing recess 322b provided in the attaching portion (attaching hole 322a) of the lower frame 32 of the outer shoji 3, but not limited to this. Alternatively, the cleaving introduction convex portion 511d may be provided at 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 dehiscence introduction convex portion 511 d has a triangular shape at a portion between the flange portion 512 and the engaging piece 513 on the side surface of the door end of the case member 51. It is formed as a protruding protrusion.
On the other hand, as shown in FIG. 8(c), a storage recess 322c is formed at the door edge side of the mounting hole 322a of the lower frame 32, and as shown in FIG. In the state of being attached to the mounting hole 322a, the cleaving introduction convex portion 511d of the sub block 5 is arranged in the storage concave portion 322c of the mounting hole 322a.

In this way, by providing the cleaving introduction convex portion 511d on the side surface of the door block of the sub block 5, the sub block 5 is strongly pressed against the door side of the mounting hole 322a of the lower frame 32 by a strong prying force by a bar or the like. When the upper and lower door edge sides of the storage recess 322c of the mounting hole 322a are deformed, the cleaving introduction convex portion 511d of the sub block 5 is attached to the door edge side of the storage recess 322c of the mounting hole 322a of the lower frame 32. It guides the contact and tears open, and the sub block 5 moves to the door end side without being embedded in the resin lower frame 322 of the lower frame 32, so that it is possible to maintain the state of projecting on the indoor side surface of the lower frame 32. ..

Although the dehiscence introducing portion in the present embodiment is formed by the dehiscence introducing convex portion provided on the door tip side portion of the sub block, the door tip of the attachment hole of the lower frame is formed by pressing the sub block. The shape and the like are not limited as long as the resin lower frame on the side can be torn open and moved.
Further, in the present embodiment, the sliding shoji is adopted as the shoji, but the sliding shoji on the indoor side may be a fixed sliding shoji.
Further, the horizontal frame may be an upper frame, a lower frame, or another horizontal frame. Further, it may be a composite frame member formed of a resin member on the indoor side and an aluminum member on the outdoor side, or may be a resin frame member entirely formed of a resin member. It suffices that the indoor side portion in which is arranged is formed of a resin member.
