Description

The present invention relates to a fitting equipped with a stopper that restricts the movement of a sliding screen that can slide in the viewing direction.

Conventionally, as a stopper that restricts the movement of a shoji screen that can slide in the viewing direction, a fitting equipped with a stopper structure that ensures the remaining dimension by abutting one of two sliding shoji screens against the other shoji screen (see, for example, Patent Document 1) has been known (see, for example, Patent Document 1). The stopper structure of this fitting has an attachment part and a stopper part, and is provided on the door edge sides of the upper and lower frames of the shoji screens.

Auxiliary locks attached to the horizontal frame of a sliding door are also known as stoppers that are attached to the upper and lower frames of a shoji screen and restrict its movement. Some auxiliary locks are installed on the indoor side of the outer shoji screen so that they come into contact with the inner shoji screen as it moves. The auxiliary lock is attached, for example, by inserting the auxiliary lock longitudinally into an attachment hole formed on the indoor side wall of the horizontal frame of the outer shoji screen, which is a notch extending longitudinally from the end of the horizontal frame, while engaging it, and then butting the edge of the horizontal frame against the vertical frame to join the horizontal frame and the vertical frame.

JP 2020-105839 A

The shoji stoppers installed in the above-mentioned conventional fittings are inserted into mounting holes in the horizontal frame like auxiliary locks, and the vertical frame is butted up against the small edge of the horizontal frame to attach the auxiliary lock. Therefore, when replacing the stoppers due to wear and deterioration over time, the horizontal frame and the vertical frame must be separated. This poses the problem of poor workability when replacing the stoppers.

In addition, because the stopper is attached by inserting it into a mounting hole provided at the joint between the vertical and horizontal frames, there was an issue that rattles could easily occur between the vertical and horizontal frames and the stopper due to dimensional tolerances of each component, clearances between components, and even the impact when the shoji screen collides.

The present invention was made in consideration of these problems, and its purpose is to provide a fixture with a stopper that is easy to replace and less likely to cause rattling.

In order to achieve this purpose, the fitting of the present invention comprises a frame body, and a plurality of shoji screens arranged in a line in the front direction, including at least one movable shoji screen supported by the frame body and slidable in the front direction, and a stopper is provided on one of the movable shoji screens or an adjacent shoji screen adjacent to the movable shoji screen, and abuts against the other shoji screen to maintain the relative position between the movable shoji screen and the adjacent shoji screen, the stopper having an insertion portion that is inserted through an opening provided on the surface of one of the shoji screens facing the other shoji screen, and engages with the one of the shoji screens to restrict movement in the out-of-plane direction, and an engagement portion that releases the restriction when operated, and a main body member having a protrusion into which the insertion portion is inserted and protruding from the one of the shoji screens, and an elastic member having higher elasticity than the main body member, a shoji abutment portion that is attached to the protrusion portion and against which the other shoji screen abuts, and an intermediate portion that is arranged between the main body member and the portion that forms the opening.
Other features of the present invention will become apparent from the following detailed description of the present invention and the accompanying drawings.

The present invention makes it possible to provide fittings with stoppers that are easy to replace and less likely to cause rattles.

Hereinafter, a fitting according to an embodiment of the present invention will be described with reference to the drawings.
In this embodiment, as shown in Figures 1 and 2, a bathroom fitting 4 is provided between a bathroom and a dressing room, and has a fitting frame 3 that supports two sliding screens 1 and 2 so that both can slide left and right. In the following explanation, the movable screen provided on the dressing room side of the two movable screens is referred to as the first screen 1, and the adjacent movable screen provided on the bathroom side adjacent to the first screen 1 in the forward direction is referred to as the second screen 2.

In the following explanation, when the fitting 4 attached to a building is viewed from the bathroom side, the direction that is up and down is referred to as the up-down direction, the direction that is left and right is referred to as the left-right direction, and the depth direction that is the inside and outside of the bathroom is referred to as the prospective direction. Even when each part of the fitting 4 or each component that makes up the fitting 4 is in a separate state, the directions are specified and explained in terms of the up-down, left-right, and prospective directions when the fitting 4 is attached to the building.

In this embodiment, the fitting 4 is provided with a stopper 5 on the first shoji 1 that contacts the second shoji 2 to ensure a certain amount of clearance when the first shoji 1 and second shoji 2 are opened, as shown in Figure 3. The first shoji 1 is provided with a handle 1b on the door end frame 12 to be grasped when sliding the first shoji 1, and the stopper 5 is provided at the joint between the upper and lower horizontal frames 11 and the door end frame 12 of the first shoji 1, protruding toward the inside of the bathroom, as shown in Figure 4. Note that Figure 4 shows the stopper 5 provided on the lower side.

Therefore, when the handle 1b is grasped and the first shoji 1 is slid in the opening direction (to the left), the stopper 5 hits the interlocking frame 23 of the second shoji 2, restricting the movement of the first shoji 1 in the opening direction, and the relative positions of the first shoji 1 and the second shoji 2 are maintained, ensuring a gap between the interlocking frame 23 of the second shoji 2 and the handle 1b.

The first shoji screen 1 has a surface material 1a, such as glass, and a frame 10 that houses the peripheral edge of the surface material 1a. The frame 10 has two horizontal frames 11 arranged above and below the surface material 1a, and a door end frame 12 and a door frame 13 arranged on the left and right of the surface material 1a, against which the small edges of the horizontal frames 11 abut to form a frame with the horizontal frames 11.

The two horizontal frames 11, the end frame 12, and the joint frame 13 are all made of extruded aluminum, and each has a hollow portion 11a, 12a, 13a that runs through it in the longitudinal direction.

The two horizontal frames 11 form a hollow portion 11a, and have a horizontal exterior wall portion 11b that faces the front direction and forms the visible surface on the dressing room side, and a horizontal interior wall portion 11c that forms the visible surface on the bathroom side. The upper horizontal frame 11 has a narrower gap between the horizontal exterior wall portion 11b and the horizontal interior wall portion 11c toward the bottom, and a surface material storage portion 11d is provided at the bottom to accommodate the upper end of the surface material 1a. The lower horizontal frame 11 has a narrower gap between the horizontal exterior wall portion 11b and the horizontal interior wall portion 11c toward the top, and a surface material storage portion 11d is provided at the top to accommodate the lower end of the surface material 1a.

The door frame 12 forms a hollow section 12a with a horizontal cross section that is approximately rectangular, and has a vertical inner wall section 12b that faces the left and right direction and is located on the inner side of the frame 10 to form a visible surface, a vertical outer wall section 12c that faces the outer side of the frame 10 to form a visible surface, a vertical outer wall section 12d that faces the visible direction and is located on the dressing room side, i.e., outside the bathroom, to form a visible surface, and a vertical inner wall section 12e that is located inside the bathroom and forms a visible surface. A surface material 12f that accommodates the side end of the surface material 1a along the longitudinal direction is provided on the vertical inner wall section 12b, approximately in the center in the visible direction.

The vertical exterior wall 12d and the vertical interior wall 12e have inner peripheral extensions 12g that extend slightly inward beyond the vertical interior wall 12b. At the upper and lower ends of the door end frame 12, the small ends of the upper and lower horizontal frames 11 abut against the vertical inner peripheral wall 12b between the outdoor and indoor inner peripheral extensions 12g, and screws entering from the outer periphery are screwed into the horizontal frames 11 to join the door end frame 12 and the two horizontal frames 11.

The stoppers 5 are provided at the joints between the upper and lower horizontal frames 11 and the door end frame 12. The stoppers 5 provided at the top and bottom of the frame 10 are the same, so here we will use as an example the stopper 5 provided at the joint between the lower horizontal frame (hereinafter also referred to as the lower horizontal frame) 11 and the door end frame 12.

As shown in Figures 4 and 5, when the lower horizontal frame 11 and the door end frame 12 are joined, the lower stopper 5 is inserted into an opening 10a formed by a notch 11e cut from the door end side of the horizontal interior wall 11c of the lower horizontal frame 11 toward the mating side, and an inner peripheral extension 12g of the vertical interior wall 12e. The opening 10a is located approximately in the center in the vertical direction of the flat part of the horizontal interior wall 11c of the lower horizontal frame 11, and is rectangular in shape.

First, the stopper 5 of the first embodiment will be described.
The stopper 5 of the first embodiment has a main body member 6 made of synthetic resin, and an elastic member 63 that is fitted into the main body member 6 and is made of synthetic rubber or the like and has higher elasticity than the main body member 6 .

The main body member 6 has an insertion portion 60 that is inserted into the hollow portion 11a through the opening 10a and engages with the edge 10b of the opening 10a, and a protrusion 61 that protrudes toward the bathroom interior of the frame 10 when the insertion portion 60 is inserted.

As shown in Figures 6 and 7, the insertion section 60 has an upper wall section 60a and a lower wall section 60b that face each other vertically, a left wall section 60c and a right wall section 60d that vertically connect the left and right ends of the upper wall section 60a and the lower wall section 60b, and has a hollow section 60e inside.

The upper wall portion 60a and the lower wall portion 60b are provided with an engagement portion 60f in the center in the left-right direction, which is connected only to the tip side to be inserted, i.e., the changing room side, and the left and right parts and the bathroom side part are separated. The engagement portion 60f can be flexibly deformed in the out-of-plane direction of the upper wall portion 60a and the lower wall portion 60b, with the connected part on the changing room side as a fulcrum.

The upper and lower wall portions 60g and 60h located on the left and right of the engagement portion 60f and on the changing room side of the upper and lower wall portions 60a and 60b are formed so that the length from the upper surface of the upper wall portion 60a to the lower surface of the lower wall portion 60b, i.e., the vertical width W1, is slightly narrower than the vertical width W2 (Figure 5) of the opening 10a. The bathroom side portion 60i of the upper and lower wall portions 60a and 60b has a vertical width W3 slightly wider than the width W1 of the upper and lower surface portions 60g and 60h on the changing room side, and is formed to be approximately the same as the vertical width W2 of the opening 10a. The step between the changing room side and the bathroom side of the upper and lower wall portions 60a and 60b is connected by an inclined surface that narrows toward the changing room side.

The bathroom side portion 60j of the engagement portion 60f has a vertical width W4 that is wider than the vertical width W2 of the opening 10a, and the steps between the bathroom side portion 60j and the upper surface portion 60g and the lower surface portion 60h are connected by an inclined surface that narrows toward the dressing room side. Here, the vertical width W4 of the bathroom side portion 60j of the engagement portion 60f corresponds to the width spanning the two engagement portions in the intersecting direction.

When the insertion part 60 is inserted into the opening 10a, the bathroom side part 60j is pressed against the edge 10b of the opening 10a, causing the engagement part 60f to bend toward the hollow part 60e, and when the bathroom side part 60j of the engagement part 60f passes through the opening 10a, the bending deformation of the engagement part 60f is released, restricting movement toward the bathroom side.

The end face of the engaging portion 60f, i.e., the portion where the inserting portion 60 is inserted into the opening 10a and the engaging portion 60f faces the inner surface of the horizontal interior wall portion 11c around the end of the opening 10a, is parallel to the inner surface of the horizontal interior wall portion 11c at the portion 60k away from the center in the vertical direction, and the central portion is inclined so that the distance becomes narrower toward the bathroom side, in other words, the two engaging portions 60f form an inclined portion 60l with an inclination approaching the side where they face each other from the inside to the outside of the hollow portion 11a. The portion 60k parallel to the inner surface of the horizontal interior wall portion 11c is formed so that the distance between the seat portion 61a of the protruding portion 61 described later is wider than the thickness of the horizontal interior wall portion 11c, and the distance between the bathroom side edge of the inclined portion 60l and the seat portion 61a is set slightly shorter than the thickness t of the horizontal interior wall portion 11c.

When the insertion part 60 is inserted, the right wall part 60d abuts against the vertical inner wall part 12b of the door end frame 12. The door end frame 12 has an inner peripheral extension part 12g that protrudes further inward than the vertical inner peripheral wall part 12b, so the bathroom side part of the right wall part 60d has an inclined surface 60m that inclines leftward toward the bathroom side to avoid the inner peripheral extension part 12g. When the insertion part 60 is inserted, the stopper 5 is inserted while the right wall part 60d and the inclined surface 60m are guided by the inner peripheral extension part 12g, and the right wall part 60d abuts against the vertical inner peripheral wall part 12b.

The width W5 in the left-right direction at the boundary between the insertion portion 60 and the protruding portion 61 is slightly smaller than the width W6 in the left-right direction of the opening 10a, and when the insertion portion 60 is inserted and the inclined surface 60m of the right wall portion 60d abuts against the inner peripheral extension portion 12g of the door end frame 12, a gap S is provided between the left wall portion 60c and the left edge of the opening 10a.

The left wall 60c has a protrusion 60n at the end on the dressing room side that protrudes towards the entrance frame 13, and is configured so that if the insertion part 60 is inserted incorrectly, the protrusion 60n will come into contact with the vertical inner wall 12b and the insertion part cannot be inserted.

The boundary between the protrusion 61 and the insertion section 60 protrudes above and below the bathroom side portion 60i of the upper wall section 60a and the lower wall section 60b, and the protruding portion forms a seat section 61a that abuts from the bathroom side around the opening 10a in the side room interior wall section 11c.

The protrusion 61 has an external shape in plan view that is approximately trapezoidal, with the seat 61a side as the base and the left corner forming a right angle. The trapezoidal protrusion 61 in plan view has a roughly rectangular protrusion main body 61b on the left side that is connected to the insertion part 60, and a roughly triangular rightward extension 61c extends from the protrusion main body 61b to the right.

The rightward extension 61c has a bottom surface 61d that is located closer to the bathroom interior than the seat 61a by the thickness of the vertical interior wall 12e of the door frame 12, and is configured so that the bottom surface 61d abuts against the vertical interior wall 12e when the insertion part 60 is inserted.

The left side surface of the protruding body 61b, which is perpendicular to the seat 61a, has a rectangular recess 61e recessed to the right. A circular through hole 61g is provided in the approximate center of the right recessed portion of the left side surface of the protruding portion 61, which is connected to the hollow portion 60e of the insertion portion 60 and communicates with the hollow portion 61f of the protruding portion 61. On the changing room side of the through hole 61g, a rectangular communication hole 61h is provided that communicates with the hollow portion 61f.

By providing the communication hole 61h, it is possible to operate the engagement portion 60f of the main body member 6 attached to the frame 10 from the outside using a tool, jig, etc. inserted into the communication hole 61h. Therefore, by operating the two engagement portions 60f to approach each other within the hollow portion 60e using a tool, jig, etc. inserted into the communication hole 61h, it is possible to release the engagement of the engagement portion 60f with the edge 10b of the opening 10a and remove the main body member 6.

The elastic member 63 has an elastic plate portion 63a that is substantially plate-shaped and fits into a recess 61e provided in the protruding portion 61, an elastic locking piece 63b that protrudes from the surface of the elastic plate portion 63a that faces the recess 61e and is locked into a through hole 61g provided in the protruding portion 61, and an elastic extension portion 63c that is connected to the elastic plate portion 63a and extends toward the changing room.

The stopper 5 is attached to the frame 10 with the elastic member 63 attached to the main body member 6. As shown in FIG. 8(a), the stopper 5 is attached by inserting the insertion portion 60 into the opening 10a of the frame 10 through the protrusion 60n with the frame 10 in a framed state. After the protrusion 60n is inserted, for example, the right wall portion 60d is inserted along the inner peripheral extension portion 12g of the vertical interior wall portion 12e.

As the insertion portion 60 continues to be inserted, the upper and lower engagement portions 60f come into contact with the upper and lower edges of the opening 10a, and as shown in FIG. 8(b), the engagement portion 60f is pressed toward the hollow portion 60e, causing it to bend and deform as it passes through the opening 10a. When the engagement portion 60f passes through the opening 10a, as shown in FIG. 8(c), the bending deformation of the engagement portion 60f is released, and the inclined portion 60l on the end face of the engagement portion 60f engages with the edge 10b of the opening 10a, restricting the movement of the stopper 5 toward the bathroom side. Here, the inclined portion 60l corresponds to the engagement surface that engages with the wall portion that forms the edge of the opening in the cross direction at the engagement portion.

When the engaging portion 60f passes through the opening 10a, the inclined surface 60m on the bathroom side of the right wall portion 60d is inserted along the inner peripheral extension portion 12g of the vertical interior wall portion 12e, and the stopper 5 moves to the right and the right wall portion 60d abuts against the vertical inner peripheral wall portion 12b. At this time, the elastic extension portion 63c of the elastic member 63 is clamped between the left wall portion 60c and 10b of the opening 10a, and the left-right movement of the stopper 5 is also restricted. Here, the elastic extension portion 63c corresponds to the intermediate portion disposed between the main body member and the edge of the opening.

When the first shoji screen 1 to which the stopper 5 is attached is slid in the opening direction, the elastic plate portion 63a of the elastic member 63 abuts against the joint frame 23 of the second shoji screen 2, ensuring that it remains pulled out. Here, the elastic plate portion 63a has higher elasticity than the main body member, and is attached to the protrusion and corresponds to the shoji abutment portion against which the other shoji screen abuts.

According to the fitting 4 equipped with the stopper 5 of the first embodiment, the stopper 5, which abuts against the second shoji screen 2 to maintain the relative position of the two shoji screens 1 and 2, when the insertion part 60 is inserted into the opening 10a formed by the lateral interior wall part 11c of the first shoji screen 1 and the inner peripheral extension part 12g, the engagement part 60f of the insertion part 60 engages with the lateral interior wall part 11c, restricting the movement of the main body member 6 in the outward direction of the surface, so that the main body member 6 can be attached to the first shoji screen 1 with the protrusion part 61 protruding to the outside of the first shoji screen 1.

In addition, the restriction on the out-of-plane movement of the main body member 6 can be released by manipulating the two opposing engagement parts 60f so that they approach each other, so that the main body member 6 can be moved in the out-of-plane direction by manipulating the two engagement parts 60f, making it possible to easily remove the main body member 6.

In addition, the elastic plate portion 63a of the elastic member 63, which has a higher elasticity than the main body member 6, is attached to the protruding portion 61 against which the second shoji screen 2 abuts, making it possible to reduce the impact when the second shoji screen 2 abuts. In addition, the elastic member 63 has an elastic extension portion 63c that is positioned between the main body member 6 and the edge 10b of the opening 10a, making it possible to reduce rattling of the stopper 5 inserted into the opening 10a. This makes it possible to provide a fitting 4 equipped with a stopper 5 that is easy to replace and does not easily rattle.

The insertion part 60 has two engaging parts 60f that face each other in the cross direction, and the width W4 across the two engaging parts 60f, i.e., the distance between the parts on the opposite side to the sides where the two engaging parts 60f face each other, can be deformed so as to be narrower than the width W2 of the opening 10a. Therefore, the width W4 of the two engaging parts 60f can be deformed so as to be narrower than the width W2 of the opening 10a, and the insertion part 60 can be inserted from the opening 10a into the hollow part 60e. In addition, the two engaging parts 60f are engaged with the lateral interior wall part 11c that forms the edge 10b of the opening 10a in the hollow part 60e, so that the two engaging parts 60f that have passed through the opening 10a can be restored to their original shape and engaged with the lateral interior wall part 11c that forms the edge 10b of the opening 10a, allowing the stopper 5 to be easily attached to the frame 10.

The right wall 60d of the insertion portion 60 of the main body member 6 abuts against the vertical inner wall 12b of the door frame 12 on the right side (one side) in the sliding direction, and the elastic extension 63c is sandwiched between the horizontal inner wall 11c that forms the edge 10b of the opening 10a on the left side (the other side) in the sliding direction, so that rattling in the sliding direction of the stopper 5 consisting of the main body member 6 and the elastic member 63 can be suppressed.

In addition, the inclined portion 60l of the engagement portion 60f that engages with the side chamber interior wall portion 11c that forms the edge 10b of the opening 10a within the hollow portion 11a of the lower horizontal frame 11 has an inclination that approaches the opposing side from the inside to the outside of the hollow portion 11a, so that it engages in a direction that widens the opening 10a and presses the side chamber interior wall portion 11c outward from the hollow portion 11a. As a result, a gap is unlikely to occur between the main body member 6 and the side chamber interior wall portion 11c that forms the opening 10a, so it is possible to more reliably suppress rattling of the stopper 5.

In addition, since the engaging portion 60f can be operated through the communication hole 61h while the main body member 6 is attached, it is possible to disengage the engaging portion 60f that is engaged with the edge 10b of the opening 10a and remove the main body member 6. Therefore, by removing the elastic member 63 of the attached stopper 5 and then removing the main body member 6, the stopper 5 can be easily removed.

Next, a stopper 7 according to a second embodiment will be described.
As shown in Figures 9 and 10, the stopper 7 of the second embodiment is inserted into an opening 10c formed by a notch 11e cut from the end of the horizontal interior wall 11c of the lower horizontal frame 11 to the door-end side, and an inner peripheral extension 12g of the vertical interior wall 12e when the lower horizontal frame 11 is joined to the door-end frame 12. The opening 10c is provided at approximately the center in the vertical direction of the flat part of the lower horizontal frame 11, and is formed by connecting two parts with different widths in the vertical direction. The two parts of the opening 10c are a widened hole 10d located on the door-end frame 13 side, and a narrow hole 10e located on the door-end frame 12 side.

The stopper 7 has a main body member 8 made of synthetic resin, and an elastic member 83 that is fitted into the main body member 8 and has higher elasticity than the main body member 8 .
The main body member 8 has an insertion portion 80 that is inserted into the hollow portion 11a through the opening 10c, and a protrusion portion 81 that protrudes toward the bathroom inside of the frame 10 when the insertion portion 80 is inserted.

As shown in Figures 11(a) and 11(b), the insertion section 80 has an upper wall section 80a and a lower wall section 80b that face each other vertically, and a left wall section 80c and a right wall section 80d that vertically connect the left and right ends of the upper wall section 80a and the lower wall section 80b.

The width W7 from the top surface of the upper wall portion 80a to the bottom surface of the lower wall portion 60b is slightly narrower than the width W8 from top to bottom of the narrow hole portion 10e in the opening 10c. On the bathroom side of the upper wall portion 80a and the lower wall portion 80b, there is provided an opposing piece 80e that faces the surface of the hollow portion 11a side of the edge 10f that forms the narrow hole portion 10e in the horizontal room inner wall portion 11c when the insertion portion 80 is inserted.

The width W9 between the upper end of the opposing piece 80e on the upper wall portion 80a and the lower end of the opposing piece 80e on the lower wall portion 80b is wider than the vertical width W8 of the narrow hole portion 10e and slightly narrower than the vertical width W10 of the widened hole portion 10d. Here, the opposing pieces 80e each protrude in the intersecting direction, and the distance between the protruding tips corresponds to a first engagement portion that is narrower than the widened hole portion and wider than the narrow hole portion.

A guide portion 80g is provided on the changing room side of the facing piece 80e, which is connected to the facing piece 80e and protrudes from the upper wall portion 80a and the lower wall portion 80b in the forward direction. The guide portion 80g has an inclination that gradually decreases the amount of protrusion toward the changing room side, and when the insertion portion 80 is inserted through the widening hole portion 10d, it is guided to the edge of the widening hole portion 10d.

The opposing piece 80e also has a protrusion 80f that protrudes slightly on the side opposite the guide portion 80g, i.e., toward the bathroom side, and the distance W11 between the protrusion 80f and the seat portion 81a of the protrusion 81, which will be described later, is set to be approximately equal to the thickness t of the lateral interior wall portion 11c.

When the insertion part 80 is inserted, the right wall part 80d abuts against the vertical inner wall part 12b of the door end frame 12, and the bathroom side part of the right wall part 80d is provided with an inclined part 80h that inclines leftward toward the bathroom side. When the insertion part 80 is inserted into the stopper 7, the right wall part 80d abuts against the vertical inner wall part 12b. Here, the right wall part 80d corresponds to the frame abutment part that abuts against the frame on one side in the sliding direction.

The left wall portion 80c has a left extension portion 80i that extends to the left, i.e., toward the joint frame 13. The left extension portion 80i is a plate-shaped portion having the same width as the width W7 from the top surface of the upper wall portion 80a to the bottom surface of the lower wall portion 60b, and is arranged approximately parallel to the horizontal interior wall portion 11c. The left extension portion 80i is configured such that when the insertion portion 80 is inserted and the right wall portion 80d is abutted against the vertical inner peripheral wall portion 12b of the door end frame 12, the extended tip of the left extension portion 80i is positioned on the joint frame 13 side of the widening hole portion 10d and faces the horizontal interior wall portion 11c.

The left extension 80i is provided with a protrusion 80j near the center in the vertical direction that protrudes further toward the bathroom side than other parts along the left-right direction. The tip of the protrusion 80j abuts against the lateral interior wall 11c or faces closely to the lateral interior wall 11c. In addition, a rib 80k is provided in the vertical center on the surface of the left extension 80i facing the dressing room that connects the tip of the left extension 80i to the left wall 80c. Here, the left extension 80i corresponds to the extension that extends to the other side in the sliding direction, and the tip of the protrusion 80j corresponds to the second engagement portion where the extended tip engages with the wall.

The boundary between the protruding portion 81 and the insertion portion 80 protrudes above and below the upper wall portion 80a and the lower wall portion 80b, and the protruding portion forms a seat portion 81a that abuts against the periphery of the opening 10c from the bathroom side in the lateral interior wall portion 11c.

Like the first form of stopper 5, the protrusion 81 of the stopper 7 has an external shape in plan view that is generally trapezoidal, with the seat 81a side as the base and the left corner forming a right angle. The trapezoidal protrusion 81 in plan view has a generally rectangular protrusion main body 81b on the left side that is connected to the insertion portion 80, and a rightward extension 81c that extends to the right from the protrusion main body 81b and forms a generally triangular shape.

The rightward extension 81c has a bottom surface 81d that is located closer to the bathroom interior than the seat 81a by the thickness of the vertical interior wall 12e of the door frame 12, and is configured so that the bottom surface 81d abuts against the vertical interior wall 12e when the insertion part 80 is inserted.

The left side surface of the protruding body 81b, which is perpendicular to the seat 61a, has a rectangular recess 81e recessed to the right. A circular through hole 81g that communicates with a hollow portion 81f provided within the protruding body 81b is provided in approximately the center of the rightward recessed portion on the left side surface of the protruding portion 81.

12(a) and 12(b), the elastic member 83 has an elastic side plate portion 83a that is substantially plate-shaped and fits into a recess 81e provided in the protruding portion 81, an elastic locking piece 83b that protrudes from the surface of the elastic side plate portion 83a that faces the recess 81e and is locked into a through hole 81g provided in the protruding portion 81, and an elastic flat plate portion 83c that is connected to the elastic side plate portion 83a, extends toward the joint frame 13, and is disposed along the left extension portion 80i. In other words, the elastic side plate portion 83a that fits into the recess 81e and the elastic flat plate portion 83c that fits along the left extension portion 80i form an L shape.

The elastic flat plate portion 83c has an indoor plate portion 83d located closer to the bathroom than the horizontal indoor wall portion 11c, an outdoor plate portion 83e located closer to the dressing room than the horizontal indoor wall portion 11c, and a connecting portion 83f connecting the indoor plate portion 83d and the outdoor plate portion 83e. The indoor plate portion 83d, like the elastic side plate portion 83a, has the same width as the vertical width of the protrusion portion 81, and is configured so that when the elastic member 83 is attached together with the main body member 8, the indoor plate portion 83d covers the widened hole portion 10d in the opening 10c from the outside of the lower horizontal frame 11. Here, the indoor plate portion 83d corresponds to a cover portion that covers the widened hole portion from the outside of the frame.

The connecting portion 83f is formed so that its vertical width W12 is approximately equal to the width W7 from the top surface of the upper wall portion 80a of the insertion portion 80 to the bottom surface of the lower wall portion 60b, and its left-right length is set to a length that is clamped between the main body member 8 and the edge 10f of the opening 10c on the side of the fitting frame 13 when the elastic member 83 is attached together with the main body member 8. In addition, the projected width W13 of the connecting portion 83f is set to be slightly narrower than the thickness of the lateral interior wall portion 11c.

The exterior panel portion 83e has an outer peripheral protrusion 83g that protrudes vertically and toward the joint frame 13 beyond the connecting portion 83f. The protruding tip of the outer peripheral protrusion 83g is formed so as to be positioned outside the edge 10f of the widening hole portion 10d when the elastic member 83 is attached together with the main body member 8.

The outer peripheral protrusion 83g has inclined surfaces 83h on the bathroom side and the dressing room side so that the width in the forward direction gradually narrows toward the protruding tip. The inclined surface 83h on the bathroom side engages with the edge 10f of the opening 10c when the elastic member 83 is attached together with the main body member 8.

The elastic plate portion 83c has a groove portion 83i on the side of the dressing room that runs along the left-right direction and is recessed toward the bathroom side. With the elastic locking piece 83b locked in the through hole 81g, the elastic side plate portion 83a of the elastic member 83 fits into the recess 81e, and the protrusion 80j of the left extension portion 80i fits into the groove portion 83i, so that the elastic plate portion 83c abuts against the left extension portion 80i. At this time, when the elastic plate portion 83c abuts against the left extension portion 80i, the tip of the left extension portion 80i protrudes toward the joiner frame 13 side beyond the elastic plate portion 83c.

The stopper 7 is first attached to the main body member 8 on the frame 10, and then the elastic member 83 is attached to the attached main body member 8 and frame 10. The stopper 7 is attached by inserting the insertion part 80 into the opening 10c of the frame 10 from the left extension part 80i as shown in FIG. 13(a) while the frame 10 is in a framed state. At this time, when the opposing pieces 80e provided above and below the insertion part 80 pass through the opening 10c, the main body member 8 moves to the side of the joint frame 13, i.e., the side opposite the door end frame 12, and is inserted from the widening hole part 10d side.

Next, as shown in FIG. 13(b), insert the insertion portion 80 into the lower horizontal frame 11 while rotating it so that the tip of the left extension portion 80i moves toward the horizontal interior wall portion 11c and the tip of the right extension portion 81c moves toward the vertical interior wall portion 12e of the door end frame 12.

Next, with the tip of the rightward extension 81c abutting against the vertical interior wall 12e, the main body member 8 is moved toward the door frame 12, and the right wall 80d abuts against the vertical interior wall 12b. In this state, the edge 10f of the narrow hole 10e of the opening 10c is located between the upper and lower opposing pieces 80e and the seat 81a. Also, in this state, the tip of the protrusion 80j on the left extension 80i abuts against the horizontal interior wall 11c or faces closely against the horizontal interior wall 11c.

Next, as shown in FIG. 13(c), the elastic locking piece 83b of the elastic member 83 is locked into the through hole 81g of the main body member 8 attached to the frame 10, the elastic side plate portion 83a is placed in the recess 81e, and the exterior plate portion 83e of the elastic flat plate portion 83c is inserted into the hollow portion 11a. In this state, the bathroom side inclined surface 83h of the outer peripheral protrusion 83g engages with the edge 10f of the widened hole portion 10d in the opening 10c. At this time, as shown in FIG. 14, the bathroom side inclined surface 83h of the outer peripheral protrusion 83g contacts the upper and lower edges 10f of the widened hole portion 10d in the opening 10c, so the inclined surface 83h is supported from the top and bottom and vertical movement is restricted.

The connecting portion 83f of the elastic plate portion 83c on the side of the joint frame 13 abuts against the edge 10f of the opening 10c, and the elastic plate portion 83c is clamped between the main body member 8 and the edge 10f of the opening 10c, restricting movement in the left-right direction. Here, the elastic side plate portion 83a has higher elasticity than the main body member, is attached to the protruding portion, and corresponds to the shoji abutment portion against which the other shoji abuts, and the elastic plate portion 83c corresponds to the intermediate portion disposed between the main body member and the edge of the opening.

According to the fitting 4 equipped with the stopper 7 of the second embodiment, the stopper 7, which abuts against the second shoji screen 2 to maintain the relative position of the two shoji screens 1 and 2, when the insertion part 80 is inserted into the opening 10c formed by the side interior wall part 11c of the first shoji screen 1 and the inner peripheral extension part 12g, the opposing piece 80e of the insertion part 80 engages with the side interior wall part 11c, and the tip side part of the protrusion 80j abuts against the side interior wall part 11c or faces the side interior wall part 11c in close proximity, restricting the movement of the main body member 8 in the outward direction of the plane, so that the main body member 8 can be attached to the first shoji screen 1 with the protrusion 81 protruding outside the first shoji screen 1.

In addition, the elastic side plate portion 83a of the elastic member 83, which has a higher elasticity than the main body member 8, is attached to the protrusion 81 against which the second shoji screen 2 abuts, making it possible to reduce the impact when the second shoji screen 2 abuts. In addition, the elastic member 83 has a connecting portion 83f and an inclined surface 83h that are arranged between the main body member 8 and the edge 10f of the opening 10c, making it possible to reduce rattling of the stopper 7 inserted into the opening 10c.

The insertion portion 80 has two opposing pieces 80e that protrude upward and downward, which are the intersecting directions, and the distance W9 between the protruding tips of the two opposing pieces 80e is narrower than the widened hole portion 10d of the opening 10c, so the insertion portion 80 can be inserted into the hollow portion 11a from the widened hole portion 10d. The distance W9 between the protruding tips of the two opposing pieces 80e is wider than the narrowed hole portion 10e of the opening 10c, so by moving the main body member 8 with the insertion portion 80 inserted into the hollow portion 11a toward the narrowed hole portion 10e, it is possible to position the main body member 8 in a state where it does not come out of the opening 10c.

In addition, the restriction on the out-of-plane movement of the main body member 8 arranged on the narrow hole portion 10e side can be released by operating the main body member 8 so that the opposing piece 80e is positioned in the wide hole portion 10d, so that the main body member 8 can be moved in the out-of-plane direction by operating the main body member 8 that is integral with the opposing piece 80e, and can be easily removed. This makes it possible to provide a fitting 4 equipped with a stopper 7 that is easy to replace and does not easily rattle.

In addition, when the opposing piece 80e is engaged with the narrow hole 10e, the right wall 80d abuts against the door frame 12 on the right side in the sliding direction, restricting the movement of the main body member 8 to the right in the sliding direction.

In addition, when the right wall portion 80d is in contact with the door end frame 12 on the right side in the sliding direction, the left side in the sliding direction clamps the side interior wall portion 11c that forms the edge 10f of the widening hole portion 10d between the interior plate portion 83d of the elastic member 83 that covers the widening hole portion 10d from the outside of the lower horizontal frame 11 and the inclined surface 83h on the bathroom side, so that it is possible to suppress rattling in the sliding direction of the stopper 7 consisting of the main body member 8 and the elastic member 83.

The bathroom-side inclined surface 83h is inclined from the inside to the outside of the hollow portion 11a, and from the outer periphery to the inside, and engages with the lateral interior wall portion 11c that forms the edge 10f of the opening 10c, engaging in a direction that widens the opening 10c and pressing the lateral interior wall portion 11c outwardly of the hollow portion 11a. This makes it possible to more reliably clamp the lateral interior wall portion 11c that forms the edge 10f of the widening hole portion 10d between the interior plate portion 83d and the bathroom-side inclined surface 83h, and more reliably suppress rattling of the stopper 7.

In the above embodiment, an example was described in which the openings 10a, 10c to which the stoppers 5, 7 are attached are formed by a notch 11e provided in the horizontal chamber inner wall portion 11c and an inner peripheral extension portion 12g, but this is not limited to this and the openings may be, for example, rectangular openings provided in the horizontal or vertical frame.
In the above embodiment, an example was described in which the stoppers 5, 7 are provided on the first shoji screen 1, but they may also be provided on the second shoji screen.

In the above embodiment, the fitting 4 is described as having two shoji screens 1 and 2, but this is not limiting. For example, any fitting having multiple shoji screens, including at least one movable shoji screen, may be used. In addition, if multiple shoji screens are used, a stopper that abuts against the other one of the movable shoji screens and the adjacent shoji screen adjacent to the movable shoji screen may be provided.

In the above embodiment, the fittings are described as having two movable shoji screens, 1 and 2, that can slide left and right, but the present invention is not limited to this. For example, one of the two adjacent shoji screens in the forward direction may be a fixed shoji screen, in which one is fixed to a frame or the like.

Furthermore, the above-described embodiment is for the purpose of facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents thereof.
The present embodiment includes at least the following inventions.

A fitting comprising a frame body, at least one movable shoji screen supported by the frame body and slidable in the front direction, and a plurality of shoji screens arranged in the front direction, and a stopper provided on either one of the movable shoji screens or an adjacent shoji screen adjacent to the movable shoji screen, abutting against the other shoji screen to maintain the relative position between the movable shoji screen and the adjacent shoji screen, the stopper being inserted from an opening provided on the surface of one of the shoji screens facing the other shoji screen, engaging with the one shoji screen to restrict movement in the out-of-plane direction, and releasing the restriction by operation; a main body member having an insertion portion having an engagement portion into which the insertion portion is inserted and which protrudes from the one of the shoji screens; an elastic member having a higher elasticity than the main body member, a shoji abutment portion attached to the projection portion to which the other shoji screen abuts, and an intermediate portion arranged between the main body member and a portion forming the opening.

With this type of fitting, the stopper, which abuts against the other shoji screen to maintain the relative position of the two screens, has an insertion part that, when inserted into an opening in the wall of one of the shoji screens, engages with the engagement part of the insertion part and restricts movement in the out-of-plane direction, so it is possible to provide the stopper on one of the shoji screens with its protruding part protruding outside the one of the shoji screens. In addition, the engagement part can be operated to release the restriction on movement in the out-of-plane direction, so it can be operated to move it in the out-of-plane direction and remove the main body member.

In addition, the protrusion against which the other shoji screen comes into contact is fitted with a shoji screen contact portion made of an elastic member with higher elasticity than the main body member, making it possible to reduce the impact when the other shoji screen comes into contact. In addition, the elastic member has an intermediate portion that is placed between the main body member and the part that forms the edge of the opening, making it possible to reduce rattling of the stopper inserted into the opening. This makes it possible to provide a fixture that is equipped with a stopper that is easy to replace and less likely to rattle.

Such a fitting is characterized in that the opening is provided in a wall portion that constitutes one of the shoji screens and forms the surface of the other shoji screen side of a frame having a hollow portion, the insertion portion has a frame abutment portion that abuts the frame on one side in the sliding direction of the movable shoji screen , and two engaging portions that face each other in a transverse direction that intersects with the sliding direction, the two engaging portions are flexibly deformable so that the width spanning the two engaging portions in the transverse direction is narrower than the width of the opening, and the opening is engaged with the wall portion that forms the edge of the opening within the hollow portion, and the intermediate portion is clamped between the wall portion and the main body member on the other side of the opening in the sliding direction.

With this type of fitting, the insertion part has two engaging parts that face each other in the cross direction, and the width across the two engaging parts, i.e., the distance between the parts on the opposite side to where the two engaging parts face each other, can be flexibly deformed to be narrower than the width of the opening, so that the width of the two engaging parts can be flexibly deformed to be narrower than the width of the opening, and the insertion part can be inserted through the opening into the hollow part. Also, the two engaging parts are engaged with the wall part that forms the edge of the opening within the hollow part, so that the two engaging parts that pass through the opening can be restored to their original flexural deformation, and can be engaged with the wall part that forms the edge of the opening, making it possible to easily attach the stopper to the frame.

In addition, the frame abutment portion of the insertion portion of the main body member abuts against the frame on one side in the sliding direction, and the intermediate portion is sandwiched between the insertion portion and the wall portion that forms the edge of the opening on the other side in the sliding direction, so it is possible to suppress rattling in the sliding direction of the stopper, which is made of the main body member and elastic member.

In such fittings, the engaging surfaces of each of the engaging portions that engage with the wall portion that forms the edge of the opening in the cross direction are inclined toward the opposing sides from the inside to the outside of the hollow portion.

With this type of fitting, the engagement surfaces of the engagement parts that engage with the wall parts that form the edge of the opening in the hollow part have an inclination that approaches the opposing sides from the inside to the outside of the hollow part, so they engage in a direction that widens the opening and presses the wall parts outwardly of the hollow part. As a result, gaps are less likely to occur between the main body member and the wall parts that form the opening, making it possible to more reliably suppress rattling of the stopper.

The fixture is characterized in that the main body member, when attached to one of the shoji screens, has a communication hole that connects the portion where the engagement portion is located, which engages with the wall portion that forms the edge of the opening in the cross direction, to the outside.

With this type of fitting, the engaging part can be operated through the communication hole while the main body member is attached, so the engaging part that is engaged with the edge of the opening can be disengaged, making it easier to remove the main body member.

In such a fitting, the opening is provided in a wall portion that constitutes the one of the shoji screens and forms the surface of the other shoji screen side of the frame having a hollow portion, and the opening has a wide hole portion that is wide in a cross direction that crosses the sliding direction, and a narrow hole portion that is narrow in the cross direction, and the insertion portion has a frame abutment portion that abuts against the frame on one side in the sliding direction, and a space between the protruding tip portions. a first engaging portion that is narrower than the widened hole portion and wider than the narrow hole portion, and an extending portion that extends to the other side in the sliding direction and forms a second engaging portion whose extended tip portion engages with the wall portion, and when the frame abutment portion is abutted against the frame, the first engaging portion engages with the wall portion that forms the edge of the narrow hole portion, and the second engaging portion engages with the wall portion on the other side in the sliding direction of the opening,
The elastic member has a cover portion that covers the widened hole portion from the outside of the frame, and is characterized in that the wall portion that forms the edge of the widened hole portion is clamped between the intermediate portion and the cover portion.

According to this type of fitting, the insertion portion has two first engagement portions each protruding in a cross direction, and the distance between the protruding tips of the two first engagement portions is narrower than the widened hole portion of the opening, so the insertion portion can be inserted into the hollow portion from the widened hole portion. Also, since the distance between the protruding tips of the two first engagement portions is wider than the narrowed hole portion of the opening, it is possible to position the main body member with the insertion portion inserted into the hollow portion toward the narrowed hole portion side so that the main body member does not fall out of the opening. Also, the main body member positioned on the narrowed hole portion side can be easily removed by moving the first engagement portion to the widened hole portion and pulling out the insertion portion.

In addition, when the first engagement portion is engaged with the narrow hole portion, the frame abutment portion abuts against the frame on one side in the sliding direction, restricting movement of the main body member to one side in the sliding direction. Furthermore, at this time, the second engagement portion, which is the tip of the extension portion, engages with the wall portion within the hollow portion on the other side in the sliding direction, preventing the tip of the extension portion from slipping out of the opening.

In addition, when the frame contact portion is in contact with the frame on one side in the sliding direction, the wall portion that forms the edge of the widening hole is clamped on the other side in the sliding direction by the cover portion of the elastic member that covers the widening hole portion from the outside of the frame and the intermediate portion, so it is possible to suppress rattling in the sliding direction of the stopper made of the main body member and elastic member.

Such a building fixture is characterized in that the intervening portion has an inclined surface that slopes from the outer periphery to the inside toward the outside of the hollow portion, and the inclined surface engages with the wall portion that forms the edge of the widened hole portion.

According to this type of fitting, the intermediate part engages with the wall part that forms the edge of the opening with its inclined surface that slopes inward from the outer periphery toward the inside and outside of the hollow part, so that it engages in a direction that widens the opening and presses the wall part outwardly of the hollow part. Therefore, the intermediate part and the cover part can more reliably hold the wall part that forms the edge of the widened hole part, and it is possible to more reliably suppress rattling of the stopper.
