Hereinafter, a barrier-free fitting A according to an embodiment of the present invention will be described with reference to the drawings.
In the following description, the same reference numerals in different drawings indicate parts having the same functions, and duplicated descriptions in each drawing will be omitted as appropriate.

[Configuration of Barrier-Free Fittings]
As shown in Figures 1 and 2, the barrier-free fitting A is a sash having a sliding window in which an inner shoji (shōji) 1 and an outer shoji (shōji) 2 are arranged so that they can slide freely in the width direction, and is equipped with a barrier-free structure B.
The barrier-free fixture A has an inner screen 1 and an outer screen 2 that are arranged so as to be freely slidable in the width direction (hereinafter referred to as the left-right direction) relative to a window frame 3 fixed to the inner circumference of an opening a1 of a main body a.

As shown in Figures 1 and 2, the inner screen 1 and the outer screen 2 each have a four-sided frame structure with upper and lower frames 1a, 1b, 2a, and 2b and left and right vertical frames 1c, 1d, 2c, and 2d, and are configured by arranging panels 1e and 2e of glass or the like on the inner periphery and by arranging rollers f on the outer periphery below the lower frames 1b and 2b.
The roller f is used in the barrier-free fitting A as described below, and is replaced with the existing roller c1 described below when making the fitting barrier-free.

As shown in Figures 1 and 2, the window frame 3 has a four-sided framework structure having upper and lower frames 3a, 3b and left and right vertical frames 3c, 3d, and is fixed to the inner periphery of the opening a1 of the body a.
An indoor rail 30b and an outdoor rail 31b are provided across the entire left-right area of the lower frame 3b.
The rollers f of the inner screen 1 are placed on the indoor inside rail 30b, and the rollers f of the outer screen 2 are placed on the outdoor outside rail 31b, so that the inner screen 1 and the outer screen 2 are guided by the indoor inside rail 30b and the outdoor outside rail 31b, respectively, to open and close in the left and right direction.

[Barrier-free structure]
Next, the barrier-free structure B of the barrier-free fitting A will be described with reference to Figs.
In addition, the barrier-free structure B reduces the step on the inner periphery of the lower frame 3b and also reduces the step between the inner periphery of the lower frame 3b and the floor surface a2 inside the room.

The barrier-free structure B is installed to extend over the lower frames 1b, 2b and lower frame 3b of the inner and outer screens 1, 2.
As shown in Figure 3, on the inner and outer screens 1 and 2, a lower frame support material 4 is provided in the recesses 10b and 20b on the lower outer periphery of the lower frames 1b and 2b of the inner and outer screens 1 and 2.
Since the configuration of the bottom frame support material 4 and the configuration of the wheel f of the inner and outer screens 1 and 2 are the same for both, the following will explain the configuration of the bottom frame support material 4 and the wheel f on the inner screen 1 side, and will omit explanations of the configuration of the bottom frame support material 4 and the wheel f on the outer screen 2 side by assigning the same symbols.

(Configuration of lower frame support material)
As shown in Figures 4 and 5, the bottom frame auxiliary material 4 has an engaging portion 4a that engages with the recesses 10b, 20b of the bottom frame 1b, and a hanging piece 4b that is connected to the bottom of the engaging portion 4a on the outside side of the room, and its longitudinal length is formed across the entire left-right area of the shoji screen 1.

As shown in Figures 4 and 5, the fitting portion 4a is formed in a downward concave shape, a through hole 400 through which the door roller f passes is provided in the upper wall 40a, and a protrusion 401 is protruded from the outer surface of the wall surface 40 on the outdoor side.
When the fitting portion 4a is fitted into the recesses 10b, 20b, the upper wall 40a abuts against the upper walls 11b, 21b of the recesses 10b, 20b.
The through hole 400 is connected to the through holes 12b, 22b provided in the upper walls 11b, 21b of the recesses 10b, 20b, and when the door roller f is installed, the door roller f is inserted through the through hole 400 so that the door roller f passes through the through holes 12b, 22b.

As shown in Figures 4 and 5, the protrusion 401 is positioned so that when the fitting portion 4a is fitted into the recesses 10b, 20b, the lower surface of the protrusion 401 is approximately flush with the upper surface of the engagement portion 100 provided on the outside of the room within the recesses 10b, 20b.
This allows the protrusion 401 to engage with the upper surface of the engagement portion 100 provided on the exterior side of the recesses 10b, 20b when the engagement portion 4a is engaged in the recesses 10b, 20b.
In addition, the wall surface 42a on the indoor side of the fitting portion 4a is configured so that when the fitting portion 4a is fitted into the recesses 10b, 20b, the lower end of the wall surface 42a engages with the upper surface of the engagement portion 101 provided on the indoor side within the recesses 10b, 20b.
Such a fitting portion 4a is fixed by screwing a screw (not shown) from below with the upper wall 40a in contact with the upper walls 11b, 21b of the recesses 10b, 20b.

As shown in Figures 4 and 5, the hanging piece 4b is provided facing downward on the lower end of the exterior side wall surface 41a of the fitting portion 4a, and is provided so as to protrude downward from the lower end of the lower frame 1b.
The length of the hanging piece 4b is such that its lower end is below the lowermost end of the roller 2f of the door wheel f and is adapted to be received in a guide groove 7, which will be described later.

(Configuration of door roller mounting structure)
As shown in Figs. 4 and 5, a fitting recess 402 into which the outdoor surface of the adapter 1f of the roller f is fitted is formed on the inside of the outdoor side wall surface 41a of the fitting portion 4a.
Further, the exterior wall surface 41a and the interior wall surface 42a are respectively formed with fitting holes 403, 404 into which the engaging projection 11f provided on the adapter 1f passes and is fitted.
The fitting holes 403, 404 are provided at positions such that the lower edges of the fitting holes 403, 404 are substantially flush with the upper surface of the engagement portion 101 when the fitting portion 4a is fitted into the recesses 10b, 20b.

(Configuration of Door Rollers)
As shown in Figures 4 and 5, the door roller f is provided with the above-mentioned adapter 1f for mounting to the lower frame 1b.
The adapter 1f has an abutment portion 10f that abuts against the inner peripheral side of the upper walls 130, 131 of the hollow portions 13b, 23b of the lower frame 1b, and an engagement protrusion 11f that engages with the upper surfaces of the engagement portions 100, 101 in the recesses 10b, 20b.
This adapter 1f is formed so that when the abutment portion 10f abuts against the upper walls 130, 131, the engagement protrusion 11f engages with the upper surfaces of the engagement portions 100, 101, and the lower side of the roller 2f of the door wheel f protrudes downward from the lower end of the lower frame 1b.
This ensures that when the roller 2f is placed on the indoor rail 30b and the outdoor rail 31, a space is created between the lower end of the bottom frame 1b and the inner side of the bottom frame 3b, which has been raised to approximately the same level as described below, thereby preventing interference between the shoji screens 1, 2 and the inner side of the bottom frame 3b.

As shown in Figure 4, when the roller f is attached to the lower frame 1b, the abutment portion 10f abuts against the upper walls 130, 131 of the hollow portions 13b, 23b of the lower frames 1b, 2b, and the engagement protrusion 11f engages with the upper surfaces of the engagement portions 100, 101, so that the adapter 1f is clamped between the upper walls 130, 131 of the lower frames 1b, 2b and the upper surfaces of the engagement portions 100, 101.
In addition, when the roller f is attached to the lower frame 1b, the exterior side surface of the adapter 1f is fitted into the fitting recess 402, and the engagement protrusion 11f penetrates the fitting holes 403, 404 of the fitting portion 4a and engages with the engagement portions 100, 101.

In other words, the adapter 1f of the door roller f attached to the lower frame 1b is held by being clamped between the upper walls 11b, 21b and the upper surfaces of the engagement portions 100, 101, so there is no need to use screws or the like to fix the door roller f when installing it, thereby making it easier and quicker to install barrier-free building fixtures.
In addition, when the adapter 1f is attached to the lower frame 1b, the outdoor side surface of the adapter 1f is fitted into the fitting recess 402, and the engagement protrusion 11f penetrates the fitting holes 403, 404 of the fitting portion 4a and engages with the engagement portions 100, 101, thereby ensuring a reliable attachment of the door roller f without the need for screws, etc.

On the other hand, on the lower frame 3b side, as shown in Figure 3, there is provided an exterior lower frame auxiliary material 5a arranged in the exterior recess 300 of the lower frame 3b, an intermediate lower frame auxiliary material 5b arranged in the intermediate recess 301 between the interior rail 30b and the exterior rail 31b of the lower frame 3b, a flat material 5c arranged in the interior recess 302 of the lower frame 3b, and rail auxiliary materials 6 provided on the upper end of the interior rail 30b and the upper end of the exterior rail 31b.
In addition, the aforementioned guide groove 7 is provided between the lower frame reinforcement material 5a and the exterior side rail 31b, and between the lower frame reinforcement material 5b and the interior side rail 30b.

(Configuration of lower frame support material)
The lower frame reinforcement members 5a, 5b and the flat member 5c are formed so that their longitudinal length extends across the entire left-right area of the lower frame.
As shown in Figure 6, the lower frame reinforcement members 5a, 5b and the flat member 5c are formed so that their respective upper surface portions 50a, 50b, 50c are approximately the same height as the upper ends of the indoor inner rail 30b and the outdoor outer rail 31b.
In other words, the lower frame auxiliary materials 5a, 5b and the flat material 5c raise the exterior recess 300, the intermediate recess 301, and the interior recess 302, thereby reducing the step along the entire inner circumference of the lower frame 3b and also reducing the step between the inner circumference of the lower frame 3b and the floor surface a2 on the indoor side.

As shown in Figure 6, the lower frame reinforcement material 5a has an upper surface portion 50a, and a fixed wall 51a and a support wall 52a provided below the upper surface portion 50a.
This lower frame auxiliary material 5a has an upper surface 50a that straddles the upper end of the outdoor wall portion 303 of the outdoor recess 300 of the lower frame 3b, a fixed wall 51a that faces the outer surface of the outdoor wall portion 303 and is fixed to the outdoor wall portion 303 by screwing or the like, and a support wall 52a that is fitted into the outdoor recess 300.
A space 7a for receiving the hanging piece 4b is provided above the support wall 52a.

As shown in Figure 6, the lower frame reinforcement material 5b has an upper surface portion 50b and two support walls 51b, 52b located inside and outside and provided below the upper surface portion 50b, and is fitted into the intermediate recess 301.
A space 7a for receiving the hanging piece 4b is provided on the upper side of the support wall 51a on the indoor side.

(Configuration of flat material)
As shown in FIG. 6 , the flat member 5 c has an upper surface portion 50 c and two support walls 51 c , 52 c provided below the upper surface portion 50 c , and is fitted into the indoor recess 302 .

(Configuration of rail support material)
As shown in Figure 6, the rail auxiliary material 6 has a guide ridge 6a at its upper end for supporting the roller 2f of the door wheel f to guide the rolling of the roller 2f, and also has an airtight material retaining portion 6b provided on the outside of the upper surface 6a, and is fitted and attached to the upper ends of the indoor side rail 30b and the outdoor side rail 31b.
The airtight material holding portion 6b is configured to hold the airtight material 60 within the outdoor side recess 300 and the intermediate recess 301 of the lower frame 3b.

(Configuration of Guide Groove)
As shown in FIG. 6, the guide groove 7 is composed of a receiving space 7a and an opening 7b on the upper surface side which communicates with the receiving space 7a.
The guide groove 7 is formed between the outdoor end of the airtight material retaining portion 6b and the indoor end of each of the lower frame auxiliary materials 5a, 5b.
The position of the opening 7b is directly opposite the hanging piece 4b in the vertical direction, so that when the inner and outer screens 1, 2 are attached to the lower frame 1b, the hanging piece 4b is inserted through the opening 7b.
The airtight material 60 held by the airtight material holding portion 6b is in elastic contact with the interior side surface of the swallowed hanging piece 4b, thereby suppressing rattling when the inner and outer screens 1, 2 are opened and closed.

[Method of manufacturing barrier-free fittings]
Next, a manufacturing method of the barrier-free fitting A will be described with reference to Figs.
Barrier-free fitting A is manufactured using existing non-barrier-free fitting C shown in Figure 7 (a), and by adding a barrier-free structure B to the existing non-barrier-free fitting C, the existing non-barrier-free fitting is turned into barrier-free fitting A.
Barrier-free fitting A has the same configuration as non-barrier-free fitting C in terms of the inner and outer screens 1, 2 and window frame 3, and is manufactured by providing the common inner and outer screens 1, 2 and window frame 3 with a barrier-free structure B having each of the above-mentioned components.
In the following explanation, since the inner and outer screens 1 and 2 have the same configuration, only the inner screen 1 will be illustrated and explained in some of the process diagrams.

Step 1: Remove the inner and outer screens 1 and 2 from the bottom frame 3b of the existing non-barrier-free building fixture C shown in Figure 7 (a), and remove the wheel c1 from the bottom frames 1b and 2b as shown in Figure 7 (b).
Second step: As shown in FIG. 7(c), the cover members c2, c3 and the rail support members c4, c5 are removed from the lower frame 3b of the existing non-barrier-free building fixture C shown in FIG. 7(a).
This makes it possible to attach each of the aforementioned components of the barrier-free structure B to the lower frame 1b and lower frame 3b.

The third and subsequent steps are steps for installing the barrier-free structure B.
Third step: As shown in Figure 8(a) (state of Figure 8(b)), the lower frame auxiliary material 4 is fitted into the recesses 10b, 20b from the underside of the lower frame 1b, and the upper wall 40a of the lower frame auxiliary material 4 is abutted against the upper walls 11b, 21b of the recesses 10b, 20b and fixed in place with screws (not shown).
By attaching the lower frame support material 4 to the lower frame 1b, a hanging piece 4b is provided on the lower frame 1b.

Fourth step: As shown in FIG. 8( b ), the roller f is fitted from below the fitting portion 4 a of the lower frame auxiliary material 4 .
When fitting the roller f, as described above, the roller f is inserted through the through hole 400 in the upper wall 40 of the lower frame auxiliary material 4 and the through hole 12b in the upper wall 11b of the recess 10b.
In addition, when the wheel f passes through, the abutment portion 10f of the adapter 1f abuts against the upper wall 130 of the hollow portion 13b (the state shown in Figure 4), and the wheel f is clamped and held between the bottom frame 1b and the bottom frame auxiliary material 4 as described above.
Through these third and fourth steps, one side of the barrier-free structure B can be provided on the inner screen 1, as shown in Figure 8 (c).

Fifth step: As shown in Figure 8 (d), the lower frame auxiliary materials 5a, 5b and flat material 5c are attached to the outdoor side recess 300, the intermediate recess 301 and the indoor side recess 302 of the lower frame 3b, respectively, and the rail auxiliary material 6 for the barrier-free structure B is attached to the upper ends of the indoor side rail 30b and the outdoor side rail 31b.
In other words, by attaching the lower frame reinforcement material 5a, the lower frame reinforcement material 5b, and the flat material 5c, the exterior recess 300, the intermediate recess 301, and the interior recess 302 are raised, making the inner side of the lower frame 3b approximately flush.
In addition, by attaching the rail auxiliary material 6, a guide groove 7 can be formed in the lower frame 3b.
This fifth step enables the other part of the barrier-free structure B to be provided on the lower frame 3b.

Sixth step: As shown in Figure 8 (e), the inner and outer screens 1, 2 on which one side of the barrier-free structure B is provided in the fourth step are attached to the lower frame 3b on which the other side of the barrier-free structure B is provided in the fifth step.
At this time, by placing the roller 2f of the door wheel f on the guide ridge 6a of the rail auxiliary material 6, the hanging piece 4b of the lower frame auxiliary material 4 can be swallowed into the guide groove 7.
Through this sixth step, the barrier-free fitting A can be constructed.

By carrying out the above steps 1 to 6, a barrier-free fitting A can be manufactured from an existing non-barrier-free fitting C.
In other words, since the barrier-free fitting A shares some of the components with the existing non-barrier-free fitting C, manufacturing costs can be reduced.
Furthermore, the barrier-free fitting A manufactured by this manufacturing method can have the inner periphery of the lower frame 3b have minimal irregularities and be approximately flush.

The above describes in detail the fittings according to the embodiments of the present invention with reference to the drawings, but the specific configuration is not limited to these embodiments, and the present invention includes design changes that do not deviate from the gist of the present invention.

Furthermore, the above-mentioned embodiments can be combined by reusing each other's technologies, so long as there are no particular contradictions or problems in their purpose and configuration, etc.
