Description

This disclosure relates to fittings and methods for installing fittings.

Conventionally, a known structure for fittings in buildings such as residences is to attach frames to the left and right side edges and top edge of an opening on the structure, which are the three edges of the opening, and to install a shoji screen via a hoist on an upper rail fixed to the underside of the upper frame. For example, Patent Document 1 discloses a hanging door in which the upper rail is fitted and fixed into a groove in the upper frame, which is fixed to the underside of the structure on the ceiling side, and a hoist for suspending the shoji screen is slidably arranged on the upper rail. One method for assembling and fixing the left and right vertical frames and the upper frame into the opening of the structure is a framework construction method in which the frames are assembled into a three-sided frame in advance, and the three-sided frame is assembled and fixed all at once (Patent Document 2).

JP 2016-148202 A Japanese Patent Application Publication No. 9-287352

While the above-mentioned framework construction method makes it easy to accurately produce height and width dimensions, large opening dimensions result in increased weight and reduced workability. Also, the upper frame that secures the upper rail is sometimes hidden by the ceiling, which can result in the upper frame becoming a wasteful and unnecessary material. Therefore, the objective of this disclosure is to provide a fitting and a fitting construction method that can improve workability by reducing weight and reduce materials when constructing fittings that include upper rails.

The present disclosure relates to a fitting comprising a pair of vertical frames, an upper rail disposed between the upper ends of the pair of vertical frames, a pair of connectors that connect both ends of the upper rail to the respective upper ends of the pair of vertical frames to form a three-sided frame-shaped assembly using the pair of vertical frames and the upper rail, a shoji screen that is disposed inside an opening formed in a building structure so as to be able to open and close, and a hoist attached to the shoji screen and disposed on the upper rail, wherein the pair of vertical frames of the assembly are fixed to the respective side edges on both sides of the opening, and the upper rail of the assembly is fixed to the upper edge of the opening.

This disclosure relates to a method of construction of fittings, comprising the steps of: placing an upper rail between the upper ends of a pair of vertical frames, and connecting each of the upper ends of the pair of vertical frames to both ends of the upper rail with connectors to form a three-sided frame-shaped assembly using the pair of vertical frames and the upper rail; placing the assembly inside an opening formed in a building frame; fixing each of the pair of vertical frames to the side edges on both sides of the opening; fixing the upper rail to the upper edge of the opening; and installing a shoji screen on the upper rail via a hoist so that it can be opened and closed.

The embodiment will be described below with reference to the drawings. Figs. 1 and 2 are a front view and a back view, respectively, of a fitting 1 according to the embodiment. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1. As shown in Figs. 1 to 3, the fitting 1 is installed in an opening 2A formed in a structural body 2.

The fitting 1 according to the embodiment includes a folding door 10 serving as a shoji screen. The folding door 10 is arranged so as to be foldable inside the opening 2A. The opening 2A is formed into a vertically long rectangle when viewed from the front by a floor 3, left and right pillars 4, and a lintel 5. The framework 2 according to the embodiment includes the left and right pillars 4 and the lintel 5. In the following, expressions relating to directions such as left and right, up and down, front and back, etc. refer to the directions when the fitting 1 is installed in the opening 2A, unless otherwise noted.

The left and right side edges of the opening 2A are formed by left and right pillars 4 extending in the vertical direction. The upper edge of the opening 2A is formed by a lintel 5 extending in the horizontal direction.

The fixture 1 according to the embodiment comprises a pair of vertical frames 20 fixed to the visible surfaces of the left and right pillars 4, respectively, an upper rail 30 fixed to the visible surface of the lintel 5, and the folding door 10.

The folding door 10 has a pair of door bodies 11, 12 on the left and right, and multiple hinges 13 that connect the door bodies 11, 12 so that they can be folded upright. The door bodies 11, 12 are made of plate-like materials such as resin, glass, wood, etc., but the materials are not limited to these.

As shown in Figure 1, the door body 11 on one side (the left side in Figure 1) is provided with a handle 11a. When this handle 11a is pulled towards the front (the front side of the page in Figure 1), the folding door 10 folds while the connecting part of the door bodies 11 and 12 moves towards the front, and the door bodies 11 and 12 overlap and open.

As shown in FIG. 4, the upper rail 30 is fitted with a number of hoists 15 that enable the folding door 10 to be folded along the upper rail 30 while suspended from the upper rail 30. One hoist 15 is provided for each door body 11, 12.

As shown in Figs. 4 and 5, the hoist 15 has two rollers 17 rotatably arranged on each side of the roller support 16, door body fixing parts 18 fixed to the upper ends of the door bodies 11 and 12, and a rotating shaft 19 connecting the door body fixing parts 18 and the roller support 16. The rollers 17 of the hoist 15 are rotatably inserted into the upper rail 30, and the hoist 15 slides along the upper rail 30. Each door body 11, 12 can be folded by being rotatably supported around the rotating shaft 19. When the door bodies 11, 12 are overlapped and open, the folding door 10 can slide in either direction along the upper rail 30 via the hoist 15. The lower ends of the door bodies 11, 12 also have rollers that are attached to the lower rail 6 provided on the floor 3 and support the door bodies 11, 12 from below, but these are not shown here.

The vertical frame 20 and upper rail 30 are made of extruded metal such as aluminum. The construction method for attaching the vertical frame 20 and upper rail 30 to the opening 2A of the framework 2 as shown in Figure 6 will be described below. Note that Figure 6 shows an excerpt of the state in which the vertical frames 20 are fixed to the left and right pillars 4, respectively, and the upper rail 30 is fixed along the lintel 5, and the folding door 10 is not shown.

The outline of the construction method of this embodiment is as follows: first, a three-sided frame-shaped assembly 40 is assembled using three members, a pair of vertical frames 20 and an upper rail 30, then the assembly 40 is fixed to the opening 2A, and then the folding door 10 is hung.

As shown in Figure 7, a pair of vertical frames 20 are lined up parallel to each other on the work floor, and an upper rail 30 is placed on one end of the vertical frames 20, which will be the upper end of the vertical frames 20. When placing the upper rail 30, L-shaped metal fittings 50, which are connectors for connecting the upper rail 30 to the upper ends of each vertical frame 20, are attached to both ends, but before the L-shaped metal fittings 50 are attached, a pair of hoists 15 are placed in advance inside the upper rail 30 so that they can slide.

Figure 8 shows the L-shaped metal fitting 50 and the upper rail 30. The upper rail 30 is a long, cylindrical profile. The upper rail 30 is fixed to the visible surface along the lintel 5. The upper rail 30 has an upper plate portion 31 fixed to the lintel 5, a pair of side plate portions 32 spaced apart in the width direction of the upper rail 30 (the front-to-back direction and depth direction of the building fixture 1), and a pair of bottom plate portions 33 provided at the lower ends of each side plate portion 32.

A slit 34 extending in the longitudinal direction is formed on the underside of the upper rail 30 between the pair of bottom plate portions 33. The rotating shaft 19 of the hoist 15 is inserted into this slit 34 from one end, and the rollers 17 roll on the inner surface of the bottom plate portions 33.

A first groove 36 is formed in the center of the width direction on the upper surface of the upper plate 31 by a pair of ridges 35 extending along the longitudinal direction of the upper rail 30. The first plate 51 of the L-shaped metal fitting 50 described later fits into this first groove 36. A plurality of screw insertion holes 37 are formed at intervals in the longitudinal direction in the bottom part of the first groove 36 of the upper plate 31. The upper rail 30 is fixed to the lintel 5 by screwing screws (not shown) through the multiple screw insertion holes 37, except for the screw insertion holes 37 at the ends, from the inner side and tightening them into the lintel 5.

The L-shaped metal fitting 50 is an L-shaped metal fitting having a first plate portion 51 and a second plate portion 52 that extends substantially perpendicularly from one end of the first plate portion 51. The first plate portion 51 has a screw hole 51a. The second plate portion 52 has a screw insertion hole 52a, which is an elongated hole that extends in the direction in which the first plate portion 51 extends.

First, the first plate 51 of the L-shaped metal fitting 50 is fixed to the upper plate 31 of the upper rail 30. The L-shaped metal fitting 50 is assembled to the upper rail 30 in such a manner that the first plate 51 fits into the first groove 36 and the second plate 52 faces downward. The first plate 51 fits into the first groove 36, preventing the L-shaped metal fitting 50 from rotating. Then, the first plate 51 is fastened and fixed to the upper plate 31 of the upper rail 30 by screwing the screw 55 passed through the screw insertion hole 37 from inside the upper rail 30 into the screw hole 51a of the first plate 51. The screw 55 is inserted into the screw insertion hole 37 located at the very end of the upper rail 30. In this manner, the L-shaped metal fitting 50 is fixed to both ends of the upper rail 30. Between the end face of the upper rail 30 and the second plate portion 52 of the L-shaped metal fitting 50, there is a space into which the upper end of the vertical frame 20 fits.

Next, the upper end of the vertical frame 20 is fixed to the L-shaped metal fitting 50. Figure 9 shows the L-shaped metal fitting 50 and the upper end of the vertical frame 20. Figure 10 shows the inside of the upper end of the vertical frame 20. The vertical frame 20 has a second groove 22 on its outer surface facing the pillar 4, and a third groove 23 on its inner surface. The second plate 52 of the L-shaped metal fitting 50 fits into the second groove 22. A screw hole 22a is formed in the bottom of the second groove 22 of the vertical frame 20. In addition, the vertical frame 20 has a plurality of screw insertion holes (not shown) spaced apart in the longitudinal direction. The vertical frame 20 is fixed to the pillar 4 by screwing unillustrated screws through the screw insertion holes from the inside side into the pillar 4 and fastening them.

A spacer member 60 is attached to the upper end of the vertical frame 20. As shown in Figures 10 to 12, the spacer member 60 is an inverted L-shaped member in cross section, having an inner cover portion 61 that is placed on the inner side of the upper end of the vertical frame 20, and an upper cover portion 65 that bends and extends approximately vertically from the upper end of the inner cover portion 61. A recess 61a is provided on the inner surface of the inner cover portion 61, and a fitting piece 69 is fitted into this recess 61a. A slit 66 extending in the left-right direction is formed in the upper cover portion 65. The first plate portion 51 of the L-shaped metal fitting 50 fits into this slit 66.

The inner cover part 61 has a pair of front and rear locking pins 62 on its outer surface that protrude toward the vertical frame 20, i.e., outward. By inserting these locking pins 62 into the locking holes 29 provided at the upper end of the vertical frame 20, the spacer member 60 is attached to the inside of the upper end of the vertical frame 20. In this attached state, the inner cover part 61 fits into the third groove part 23 of the vertical frame 20 and almost covers the inside of the upper end of the vertical frame 20. The upper cover part 65 almost covers the upper end surface of the vertical frame 20. In addition, the slit 66 coincides with the second groove part 22 of the vertical frame 20 in the front-rear direction. The material of the spacer member 60 is not limited, but it is preferable that it is made of a resin or the like that does not damage the vertical frame 20 and the upper rail 30.

To fit the upper end of the vertical frame 20 into the L-shaped metal fitting 50, as shown in FIG. 13, fit the upper end of the vertical frame 20 between the end face of the upper rail 30 and the second plate portion 52 of the L-shaped metal fitting 50, fit the second plate portion 52 of the L-shaped metal fitting 50 into the second groove portion 22 of the vertical frame 20, and fit the first plate portion 51 of the L-shaped metal fitting 50 into the slit 66 of the spacer member 60. Insert the second plate portion 52 into the second groove portion 22 of the vertical frame 20 until the first plate portion 51 of the L-shaped metal fitting 50 abuts on the upper end surface of the spacer member 60, thus achieving a provisional assembly state.

As a result, the spacer member 60 is sandwiched between the upper end of the vertical frame 20 and the upper rail 30. The first plate portion 51 of the L-shaped metal fitting 50 fits into the first groove portion 36 of the upper rail 30, and the second plate portion 52 of the L-shaped metal fitting 50 fits into the second groove portion 22 of the vertical frame 20. In this state, the positions of the upper rail 30 and the vertical frame 20 in the width direction, i.e., the prospective direction as the fitting 1, are determined, and the three-sided frame-shaped assembly 40 shown in FIG. 14 is assembled. In this embodiment, the L-shaped metal fitting 50 is placed on the outer side of the vertical frame 20 and the upper rail 30.

Next, the assembly 40 assembled as described above is placed inside the opening 2A formed in the frame 2 shown in FIG. 6. That is, the assembly 40 is placed inside the opening 2A so that one vertical frame 20 faces the visible surface of one column 4, the other vertical frame 20 faces the visible surface of the other column 4, and the upper rail 30 faces the visible surface of the lintel 5. Then, the position of the assembly 40 in the visible direction is determined at a predetermined position. Next, each vertical frame 20 is fixed to the column 4, which is the side edge on both sides of the opening 2A. Each vertical frame 20 is fixed to the column 4 by screwing a screw (not shown) through a plurality of screw holes 22a formed at intervals in the longitudinal direction into the column 4 and fastening it. In addition, each vertical frame 20 is fastened to the column 4 by screwing a screw (not shown) through the screw hole 22a and the screw insertion hole 52a of the long hole of the second plate portion 52 at the top of the vertical frame 20. At this time, a peg is sandwiched between the vertical frame 20 and the column 4 as necessary. Once the work of fixing the left and right vertical frames 20 to the pillars 4 is completed, the upper rail 30 is fixed to the underside of the lintel 5, which is the upper edge of the opening 2A. This allows the vertical frames 20 and the upper rail 30 to be attached to the opening 2A of the framework 2 as shown in Figure 6.

Then, the upper ends of the door bodies 11 and 12 of the folding door 10 are attached to the hoist 15 placed on the upper rail 30, and the folding door 10 is hung on the upper rail 30 via the hoist 15 so that it can be opened and closed, thereby obtaining the fitting 1 shown in Figures 1 to 3.

The above embodiment provides the following advantages:

The fixture 1 according to the embodiment comprises a pair of vertical frames 20, an upper rail 30 arranged between the upper ends of the pair of vertical frames 20, a pair of L-shaped metal fittings 50 that connect both ends of the upper rail 30 to the upper ends of the pair of vertical frames 20 to form a three-sided frame-shaped assembly 40 with the pair of vertical frames 20 and the upper rail 30, a folding door 10 that is arranged inside an opening 2A formed in the main body 2 so as to be able to open and close, and a hoist 15 that is provided on the folding door 10 and arranged on the upper rail 30, and the pair of vertical frames 20 of the assembly 40 are fixed to the pillars 4 that are the side edges on both sides of the opening 2A, and the upper rail 30 of the assembly 40 is fixed to the lintel 5 that is the upper edge of the opening 2A.

The construction method of the fitting 1 according to the embodiment includes the steps of placing the upper rail 30 between the upper ends of a pair of vertical frames 20, connecting each of the upper ends of the pair of vertical frames 20 to both ends of the upper rail 30 with L-shaped metal fittings 50 to form a three-sided frame-shaped assembly 40 using the pair of vertical frames 20 and the upper rail 30, placing the assembly 40 inside an opening 2A formed in the main body 2, fixing each of the pair of vertical frames 20 to the pillars 4 on both sides of the opening 2A, fixing the upper rail 30 to the lintel 5, and installing a folding door 10 on the upper rail 30 via a hoist 15 so that it can be opened and closed.

In this embodiment, instead of the conventional structure in which an upper frame is fixed to the lintel 5 and the upper rail 30 is fixed to the upper frame, the upper rail 30 is fixed directly to the lintel 5, and no upper frame is used. This reduces the number of steps in construction compared to when an upper frame is used, improving construction efficiency and reducing materials. An assembly 40 in which a pair of vertical frames 20 and upper rails 30 are assembled into a three-sided frame shape is installed and fixed in the opening 2A, so the vertical frames 20 and upper rail 30 can be constructed with high precision.

In the fitting 1 according to the embodiment, at least the second plate 52 of each plate of the L-shaped metal fitting 50 has a screw insertion hole 52a formed by a long hole extending in the longitudinal direction of the vertical frame 20, and the vertical frame 20 is fixed to the column 4 of the framework 2 by a screw inserted into the screw insertion hole 52a.

This allows the L-shaped bracket 50 to be secured together with the vertical frame 20 to the main body 2 in a co-fastened state, improving the rigidity of the entire assembly 40 when secured to the main body 2.

In the fitting 1 according to the embodiment, the upper rail 30 has a first groove 36 into which the first plate 51 of the L-shaped metal fitting 50 fits, and the vertical frame 20 has a second groove 22 into which the second plate 52 of the L-shaped metal fitting 50 fits. With the first plate 51 fitted into the first groove 36 and the second plate 52 fitted into the second groove 22, the positions of the upper rail 30 and the vertical frame 20 relative to each other are determined, and the assembly 40 is put together.

This makes it easy to position the vertical frame 20 and the upper rail 30 in the three-sided frame-shaped assembly 40 in the forward direction, and allows the vertical frame 20 and the upper rail 30 to be installed together with high precision in the opening 2A of the main body 2.

In the fitting 1 according to the embodiment, it is preferable that a spacer member 60 is sandwiched between the upper end of the vertical frame 20 and the upper rail 30.

This prevents the vertical frame 20 and the upper rail 30 from coming into direct contact with each other, preventing them from scratching each other and causing damage.

The above is an embodiment of the present disclosure, but the fittings and construction methods of the present disclosure are not limited to the above embodiment, and modifications, improvements, etc. that can achieve the purpose of the present disclosure are included in the present disclosure.

For example, in the above embodiment, the second plate portion 52 of the L-shaped bracket 50 is fixed to the pillar 4 together with the vertical frame 20 by a screw passed through the screw hole 22a of the vertical frame 20 and the long screw insertion hole 52a of the second plate portion 52. The long screw insertion hole 52a may also be used as follows when assembling the upper end of the vertical frame 20 to the end of the upper rail 30 with the L-shaped bracket 50. That is, when assembling the upper end of the vertical frame 20 to the L-shaped bracket 50, the screw hole 22a of the vertical frame is aligned with the screw insertion hole 52a, and the screw passed through the screw insertion hole 52a from the outside is loosely screwed into the screw hole 22a to temporarily fix it. Next, the screw insertion hole 52a is used to adjust the longitudinal position of the vertical frame 20 relative to the L-shaped metal fitting 50, and when the height of the fitting 1 is at the specified height, the screw is tightened into the screw hole 22a to fix the second plate portion 52 of the L-shaped metal fitting 50 to the vertical frame 20.

In the above embodiment, the L-shaped bracket 50 is placed on the outside of the corner formed by the upper end of the vertical frame 20 and the end of the upper rail 30, but the L-shaped bracket 50 may also be placed on the inside of the corner to connect the two.

For example, the shoji screens disclosed herein are not limited to folding doors as in the above embodiment, but may be any type of shoji screen that is supported by being hung from an upper rail by a hoist, such as a hanging door type sliding door.

The L-shaped metal fitting 50 of the above embodiment is an example of a connector of the present disclosure, and the connector may be of any type as long as it has an integral shape of a first plate portion along the longitudinal direction of the upper rail and a second plate portion extending from one end of the first plate portion and along the longitudinal direction of the vertical frame. In addition, the upper rail 30 and vertical frame 20 of the embodiment have a first groove portion 36 and a second groove portion 22 into which the first plate portion 51 and the second plate portion 52 of the L-shaped metal fitting 50 fit, but these groove portions 36, 22 are not necessary. In addition, the spacer member 60 is provided as necessary and is not a required component.
