There is nothing.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 shows an example of a structure in which a part of the retaining wall 3 can be divided and removed, and FIG. 2 shows a vertical concave groove 8 on the fixed wall 3B side into which the rear end 3a of the movable wall 3A is fitted. 3 shows the lateral concave groove 9 of the upper frame portion 2a into which the upper end portion 3b of the movable wall 3A is fitted. FIGS. 4 (a) and 4 (b) show a state in which the sliding door 5 is closed, and FIG. FIG.

  As shown in FIG. 1, the sliding door device of the present example includes a frame 2 that forms the opening 4, and a retaining wall 3 that is provided so that either the left half or the right half of the opening 4 is the entrance 1. When the doorway 1 is opened and closed by reciprocating in the direction of opening and closing the doorway 1, a module-size sliding door 5 is provided which is stored behind the retaining wall 3. Here, one half of the retaining wall 3 on the doorway 1 side is the movable wall 3A, and the other half on the other side is the fixed wall 3B, and the rear end 3a opposite to the doorway 1 side of the movable wall 3A is the fixed wall 3B. Removably attached to the tip.

  The frame body 2 is composed of an upper frame portion 2a, left and right side frame portions 2c, a center frame 2d provided at the tip of the fixed wall 3B, and a lower frame portion 2b. As shown in FIG. 6, in addition to the guide groove 14 (FIG. 1) for guiding the upper end portion of the sliding door 5, the upper frame portion 2a has a lateral recess for rapidly fitting the upper end portion 3b of the movable wall 3A. A groove 9 is provided. The horizontal concave groove 9 also functions to prevent light leakage from the upper end portion 3b of the movable wall 3A and air gaps. In the lower frame portion 2b, apart from a guide rail (not shown) for guiding the lower end portion of the sliding door 5, an insertion groove 30 for inserting a later-described French drop 7 provided at the lower end portion of the movable wall 3A (see FIG. 13) is provided. The upper frame portion 2a may be formed in a hollow frame shape as shown in FIG.

  Further, a vertical recess groove 8 formed of a shaving groove into which the rear end portion 3a of the movable wall 3A is fitted is provided in the middle stand 2d attached to the front end portion of the fixed wall 3B. As shown in FIG. 2, a state in which light leakage from the gap between the movable wall 3A and the fixed wall 3B and a draft air are prevented by locking the rear end portion 3a of the movable wall 3A to the vertical concave groove 8 from the lateral direction. Thus, the rear end portion 3a of the movable wall 3A can be held in a state of being positioned in the front-rear direction with respect to the fixed wall 3B. A urethane cushion 16 is provided inside the vertical groove 8 to ensure adhesion. Further, a sliding contact portion 17 with the sliding door 5 is provided at the front end portion of the movable wall 3A on the entrance / exit 1 side.

  Further, in this example, a French drop 7 shown in Japanese Utility Model Publication No. 6-47552 is used as means for locking the movable wall 3A to the upper frame portion 2a and the lower frame portion 2b. As shown in FIGS. 13 and 14, this French drop 7 has a slider 25 with a lock rod 26 inserted in a cylinder 21 having a mounting plate 20 to the movable wall 3 </ b> A. When the operation rod 23 is pushed down, the lock rod 26 slides downward together with the slider 25, and the lower end of the lock rod 26 is fitted into the engagement hole 30 on the floor surface, so that the closed state of the movable wall 3A is maintained. At this time, since the claw 24 and the locking portion 26 coincide with each other, the claw 24 is automatically engaged with the locking portion 26 due to the rotation provided to the rocking body 22 by the spring 25. This prevents the slider 25 from sliding in the upward direction. Next, when releasing the engagement relationship between the lock rod 26 and the engagement hole 30, the operation rod 23 is pulled up. At this time, the rocking body 22 rotates in the clockwise direction of FIG. 13 and the claw 24 is detached from the locking portion 26. Therefore, the prevention of the slider 25 from being lifted is released, and the slider 25 is locked together with the lifting and raising of the operating rod 23.杆 26 rises. When the slider 25 is lifted just before the end of sliding, the stopper 29 formed on the leaf spring 28 is pushed away by the pin 29, and when the pin 29 gets over the stopper 27, the pin 29 and the stopper 27 are automatically engaged with each other. The structure is such that 25 drops are prevented. Reference numeral 31 denotes an insertion hole through which a screw or wood screw screwed into the movable wall 3A from the mounting plate 20 is inserted. Reference numerals 27 and 28 denote screw holes and screw portions for adjusting the length of the lock rod 26. Reference numeral 32 denotes the swinging body 22. It is a pin that is supported freely.

  Thus, for example, when carrying in a piano or large furniture larger than the entrance / exit width d, an entrance / exit width wider than usual is required. At this time, the movable door 3A can be separated from the fixed wall 3B by removing the sliding door 5 and releasing the French drop 7 on the upper and lower sides of the movable wall 3A to remove the quick-movable movable wall 3A from the frame 2. FIG. Can be widened to an opening width D (> d) wider than usual. By the way, when the doorway width d is 900 mm, the module width M of the sliding door 5 is 930 mm, for example, and the outer frame width L of the frame 2 is 1875 mm, a wide opening width D (for example, 1200 mm) can be secured by removing the movable wall 3A. It becomes like this.

  Next, when the movable wall 3A is returned, the movable wall 3A is fastened and fitted into the upper frame portion 2a and the lower frame portion 2b, and the rear end portion 3a of the movable wall 3A is vertically recessed on the fixed wall 3B. Fit into the groove 8. Thereafter, the upper and lower end portions of the movable wall 3A are respectively locked to the upper frame portion 2a and the lower frame portion 2b with the French drop 7, so that the fixed wall 3B with the movable wall 3A becomes a flat one-sided retaining wall 3, The movable wall 3A can be attached so as to protrude toward the doorway 1 side.

  Therefore, in the present invention, it is not necessary to make the outer frame width dimension L of the frame body 2 larger than the module size in advance in order to widen the entrance / exit width d, so that it can be easily accommodated in the module size of a general house. In addition, the sliding door 5 can be of a module size, and it is not necessary to manufacture a large one in advance. Therefore, there is no problem that the weight of the sliding door 5 becomes heavy. There is no manufacturing problem.

  Further, in this example, the movable wall 3A can be easily attached and locked by the French drop 7 and can be easily attached, and the movable wall 3A can be easily attached and detached without using a tool such as a screwdriver. In particular, the use of the French drop 7 in FIG. 13 eliminates the need for time-consuming operations for preventing the lock bowl from being raised and the lock bowl from being lowered. Further, light leakage and gap air from the rear end 3a of the movable wall 3A can be prevented by the vertical groove 8 and light leakage and gap air from the upper end 3b of the movable wall 3A can be prevented by the horizontal groove 9 of the upper frame 2a. In addition to being able to prevent, the structure in which the retaining wall 3 is separated into the movable wall 3A and the fixed wall 3B can be obtained as an integral continuous appearance as the retaining wall 3, and the appearance is very good.

  In this embodiment, the movable wall 3A is locked using the French drop 7, but instead, it may be fixed by bolting as shown in FIGS. In the example of FIG. 11, a long bolt 10 is used that penetrates through the inside of the movable wall 3A from the tip of the movable wall 3A on the entrance / exit 1 side and is screwed to the center stand 2d. This bolted structure has the advantage that the mounting strength of the movable wall 3A is improved and the movable wall 3A can be easily attached and detached by removing the bolt 10, and the head of the bolt 10 is movable. Since it is located at the tip of the 3A entrance / exit 1 side, the head of the bolt 10 is not seen from the indoor side, and there is an advantage that the appearance is improved.

  7 and 8 show another embodiment. In this example, there is provided swing means 11 for connecting the movable wall 3A to the fixed wall 3B so as to be bendable. The swing means 11 is composed of a pair of upper and lower hinges 11 in this example. In this example, a floor contact device (not shown) that closes the gap with the lower frame portion 2b is provided at the lower end of the movable wall 3A to prevent light leakage and airflow from the lower end of the movable wall 3A. In addition, a sense of unity between the retaining wall 3 and the frame 2 is obtained. Other configurations are the same as those of the embodiment of FIGS. 1 to 4, and corresponding portions are denoted by the same reference numerals and detailed description thereof is omitted.

  Thus, when a wider entrance / exit width is required, the French drop 7 (FIG. 13) is released and the movable wall 3A is bent as shown in FIG. It becomes possible to expand to a wide opening width D (> d). Further, at normal times, the movable wall 3A is straightly extended and the French drop 7 is locked, so that the fixed wall 3B with the movable wall 3A becomes a flat one-sided retaining wall 3. Accordingly, as in the embodiment of FIGS. 1 to 4, a wide opening width D (> d) is used as needed without significantly changing the outside frame width dimension L and using the module size sliding door 5. The effect that it can be secured easily is obtained. In addition, in this example, the movable wall 3A only swings and does not come off from the fixed wall 3B. Therefore, the opening and closing operation of the movable wall 3A becomes extremely easy and the fit of the movable wall 3A is improved.

  FIG. 9 shows still another embodiment. In this example, a slide rail 12 for removing the movable wall 3A from the fixed wall 3B and sliding it to a position facing the fixed wall 3B is provided. Other configurations are the same as those of the embodiment of FIGS. 1 to 4, and corresponding portions are denoted by the same reference numerals and detailed description thereof is omitted. The slide rail 12 of this example suspends and supports the upper guide provided on the upper end portion 3b of the movable wall 3A so that it can run freely, and moves the rear end portion 3a of the movable wall 3A in the direction of contacting and separating from the fixed wall 3B. A guide rail portion 12a for guiding freely, a pair of pull-out rail portions 12b for pulling out the movable wall 3A removed from the fixed wall 3B, and a relief for allowing the movable wall 3A to face the fixed wall 3B. Rail portion 12c. In this example, a floor contact device (not shown) that closes the gap with the lower frame portion 2b is provided at the lower end of the movable wall 3A to prevent light leakage and airflow from the lower end of the movable wall 3A. In addition, a sense of unity between the retaining wall 3 and the frame 2 is obtained. Thus, when a wider entrance / exit width is required, the French drop 7 of the movable wall 3A is released, and then the movable wall 3A is removed from the fixed wall 3B along the slide rail 12 and the rear of the movable wall 3A. The end portion 3a is extracted from the vertical groove 8 and the movable wall 3A is further pulled out to the front, and further, the outlet width d is expanded to an opening width D (> d) wider than usual by escaping to the position facing the fixed wall 3B. Can do. When returning the movable wall 3A, the movable wall 3A can be returned to the shape of protruding toward the doorway 1 by moving it in the opposite direction, and the fixed wall 3B with the movable wall 3A is a flat one-sided retaining wall 3 Become. Accordingly, as in the embodiment of FIGS. 1 to 4, a wide opening width D (> d) is used as needed without significantly changing the outside frame width dimension L and using the module size sliding door 5. The effect of being able to ensure easily is acquired. In addition, in this example, since the movable wall 3A is moved and held along the slide rail 12, the accommodation of the movable wall 3A is improved. Further, since the slide rail 12 is a suspended rail, it is not necessary to install a rail on the floor surface, and a flat floor surface can be secured.

  FIG. 10 shows still another embodiment. In the present example, the retaining wall 3 is composed of a pair of folded wall panels 3C and 3C that are connected via a hinge body 13 so as to be foldable in the horizontal direction. Further, in this example, a floor contact device (not shown) for closing the gap with the lower frame portion 2b is provided at the lower end of the pair of folded wall panels 3C, 3C, and from the lower end of the folded wall panels 3C, 3C. Light leakage and air gaps are prevented, and a sense of unity between the folded wall panels 3C and 3C and the frame 2 is obtained. Other configurations are the same as those of the embodiment of FIGS. 1 to 4, and corresponding portions are denoted by the same reference numerals and detailed description thereof is omitted.

  Therefore, if the retaining wall 3 is composed of folding wall panels 3C, 3C, and a wider entrance / exit width is required, the lock by the French drop 7 (not shown) is released and a pair of foldings are made. By simply folding the wall panels 3C and 3C around the hinge body 13, the entrance / exit width d can be expanded to an opening width D (> d) wider than usual. Further, at the normal time, the folded wall panels 3C, 3C are extended and locked by the French drop 7, so that the pair of folded wall panels 3C, 3C become a flat one-sided retaining wall 3. Accordingly, as in the embodiment of FIGS. 1 to 4, a wide opening width D (> d) is used as needed without significantly changing the outside frame width dimension L and using the module size sliding door 5. The effect of being able to ensure easily is acquired. In addition, in this example, the retaining wall 3 can be folded around the pair of folded wall panels 3C and 3C with the hinge body 13 as the center, so that the storage wall is good and the handleability is excellent.
