In addition, the "opening width direction" means the lateral width direction of the opening that is opened and closed by the opening/closing body 10, and in this embodiment, is the same direction as the "finding direction".
Additionally, "inside the frame" refers to the inside of the frame body 20, and "outside the frame" refers to the outside of the door and window frame 10.

First Embodiment
FIG. 1 shows an example of a fitting device according to the present invention.
The fixture device A is a door device (swing door) that includes an opening/closing body 10 that rotates around one end in the width direction as a fulcrum to open and close an opening, and a frame body 20 that surrounds the outer periphery of the opening/closing body 10 in the closed state.
If necessary, a waterproofing device 30 is attached to this door fitting device A so as to cover the gap s between the door leading end 10a of the opening/closing body 10 and the opposing surface 21a facing this door leading end 10a from the water intrusion side (in the illustrated example, the outdoor side).

The opening/closing body 10 is a door that opens and closes an opening inside a frame body 20, and a door end portion is pivotally supported on one of the side frame members 22 so as to be rotatable.
The opening/closing body 10 is constructed such that a front panel and a back panel are supported by framework, core material, etc. between them (see FIG. 2).

The frame body 20 is configured in the shape of a rectangular frame when viewed from the front with an opening in the center, and consists of left and right side frame members 21, 22, an upper frame member 23 connected between the upper ends of these side frame members 21, 22, and a lower frame member 24 (sometimes called a door frame) connected between the lower ends of the side frame members 21, 22 (see Figure 1).
The side frame members 21, 22, the upper frame member 23 and the lower frame member 24 are previously welded together in a factory or the like.

The inner surface of the side frame member 21 is formed with a generally L-shaped cross section (see FIG. 3) that fits into the door end of the opening/closing body 10, and an elastic airtight material 26 is provided at the indoor corner.
The inner frame surface of this side frame member 21 is an opposing surface 21a that faces the door front end portion 10a of the opening/closing body 10 with a gap s therebetween.

The elastic airtight material 26 is made of an elastic material (e.g., rubber, elastomer resin, etc.) and is formed in a long shape that extends over approximately the entire length of the side frame member 21 in the vertical direction. This elastic airtight material 26 is pressed against the indoor corner portion at the door end side of the opening/closing body 10, improving the sealing properties (airtightness, watertightness, soundproofing, etc.) of the opening/closing body 10.

The side frame member 22 has a symmetrical shape to the side frame member 21. The side frame member 22 is provided with an elastic airtight material 26 in the same manner as the side frame member 21.
Furthermore, the upper frame member 23 and the lower frame member 24 are also provided with elastic airtight materials 26 (not shown) in substantially the same manner as the side frame member 21 .

The reference numeral 25 in the figure denotes a hinge that pivotally supports the opening/closing body 10. In the illustrated example, this hinge 25 is a hinge, but other types of hinges, such as a pivot hinge, can also be used.

A gap s is provided between the door end, upper end, or lower end of the opening/closing body 10 in the closed state and the opposing surfaces 21a, 22a, 23a, and 24a of the frame body 20 that face these ends, respectively, to allow the opening/closing body 10 to rotate open and closed (see Figure 1).

The waterproofing device 30 covers the gap s between the door end 10a of the opening/closing body 10 and the side frame member 21 over the entire vertical length from the water intrusion side and is inserted into the gap s to prevent water from entering the gap.

This waterproofing device 30 has an insertion part 31 that is inserted into the gap s, a covering part 32 that covers the gap s from the water intrusion side, and a detachable part 33 that can be attached to and detached from the frame body 20 (see Figure 3).

The insertion portion 31 and the covering portion 32 are integrally molded from an elastic material (e.g., rubber or elastomer resin) with a T-shaped cross section, and are continuous over the entire vertical length of the gap s.

The insertion portion 31 is formed in a plate shape that is thinner than the width dimension of the gap s between the door end side end portion 10a and the opposing surface 21a. This configuration prevents the insertion portion 31 from rubbing against the opposing surface 21a when the opening/closing body 10 is rotated to open and close.

The covering portion 32 spans the width direction between the opening/closing body 10 and the frame body 20, and continuously covers the opening on the water intrusion side of the gap s over the entire vertical length of the gap s.
The covering portion 32 is positioned in the viewing direction by inserting the insertion portion 31 into the gap s.
One half 32 a of the covering portion 32 , separated by the insertion portion 31 , contacts the visible surface of the side frame member 21 , and the other half 32 b is adhered to the end side of the surface of the opening/closing body 10 via the detachable portion 33 .

The length of the insertion portion 31 in the projection direction is greater than half the length of the gap s in the projection direction (see FIG. 3). With this configuration, the insertion portion 31 firmly fits into the gap s, preventing the waterproofing device 30 from easily coming off, and the insertion portion 31 extending into the gap s reduces water intrusion into the gap s, thereby contributing to improved waterproofing performance.
In the illustrated example, the length of the insertion portion 31 in the prospective direction is longer than the length of the covering portion 32 in the visible direction, but other examples may include a configuration in which these two lengths are approximately equal, or a configuration in which the length of the covering portion 32 in the visible direction is longer than the length of the insertion portion 31 in the visible direction.

The detachable portion 33 is a double-sided tape, one adhesive side of which is adhered to the inner surface of the other half portion 32 b of the covering portion 32 .
The other adhesive surface of the detachable portion 33 is adhered to a portion of the outdoor side of the opening/closing body 10 near the gap s after the release paper (not shown) is peeled off.

As another example of the detachable portion 33, a band-shaped magnet can be used. This magnet is preferably a flexible magnet known as a rubber magnet. This detachable portion 33 can maintain its detachability even when repeatedly attached to and detached from the opening/closing body 10.

As another example of the detachable portion 33, an adhesive other than the double-sided tape may be used.
As yet another example, the cover portion 32 may be removably fixed to the opening/closing body 10 by fitting, screwing, or the like.
Moreover, the detachable portion 33 may be configured with a plurality of detachable means such as magnets and adhesives.

Next, the characteristic functions and effects of the fitting device A and waterproofing device 30 configured as described above will be described in detail.
When the waterproofing performance of the fitting device A needs to be improved due to heavy rain or the like, a waterproofing device 30 is attached between the opening/closing body 10 in the closed state and the side frame member 21 (see FIG. 3).
In more detail, the insertion portion 31 is inserted into the gap s between the opening/closing body 10 and the side frame member 21, and the inner corner portion between the insertion portion 31 and the detachable portion 33 is fitted into the outdoor corner portion on the door end side of the opening/closing body 10, and the detachable portion 33 is adhered to the opening/closing body 10.
The waterproofing device 30 may be attached in the initial state when the fitting device A is installed, or may be attached later after the fitting device A has been installed, for example, when heavy rain is expected.

When the waterproof device 30 is attached, the insertion portion 31 contacts the door-front end portion 10a of the opening/closing body 10, and a small gap is secured between the insertion portion 31 and the opposing surface 21a to enable the opening and closing operation of the opening/closing body 10.
In addition, the gap s between the opening/closing body 10 and the side frame member 21 is covered by the cover portion 32 over substantially the entire length in the vertical direction at the opening on the water inlet side.

When wind and rain blow against the opening/closing body 10 and the side frame member 21, the pressure of the wind and rain causes one half 32a of the cover 32 to be elastically pressed against the side frame member 21. As a result, the opening on the outdoor side of the gap s is watertightly closed by the cover 32.

Therefore, even if the elastic airtight material 26 is damaged and the sealing ability of the elastic airtight material 26 is reduced, the waterproofing device 30 can prevent water from rain or the like from entering the gap s, and further can prevent water from entering the indoor side.
Furthermore, even if there is a step between the visible surface of the side frame member 21 and the outdoor side of the opening/closing body 10, the one half portion 32a will elastically bend and fit closely to the side frame member 21 and the opening/closing body 10, thereby effectively preventing water from entering.

Furthermore, according to the above-mentioned fitting device A, even after the waterproofing device 30 is attached to the opening/closing body 10, the opening/closing body 10 can be easily opened and closed (see the two-dot chain line in FIG. 2).
Furthermore, when the influence of wind and rain is small, the waterproof equipment 30 can be easily removed by peeling the detachable portion 33 off from the opening/closing body 10.

In the above embodiment, the entire waterproof equipment 30 is made of an elastic material as a particularly preferred example, but at least the back surface side of the waterproof equipment 30 may be made of an elastic material. Specifically, only the back surface side of one half portion 32a of the covering portion 32 may be made of an elastic material.
In this way, the back surface side of the half portion 32a elastically contacts the side frame member 21 in intimate contact, thereby achieving good waterproof performance.

Second Embodiment
The fitting device, the main part of which is shown in FIG. 4, is the fitting device A described above, with the waterproofing device 30 replaced by a waterproofing device 30'.
The waterproof equipment 30' is the waterproof equipment 30 described above, in which the insertion portion 31 is replaced with an insertion portion 31'.

The insertion portion 31' has a tapered cross section that continues over the entire vertical length of the gap s. The insertion portion 31' is molded integrally with the cover portion 32 using an elastic material.

Therefore, according to the fitting device B configured as above, when the insertion portion 31' is inserted into the gap s between the opening/closing body 10 and the side frame member 21, the base end side (in other words, the root side) of this insertion portion 31' is in close contact with both the side frame member 21 and the opening/closing body 10. Also, the covering portion 32, like the waterproofing device 30, straddles the side frame member 21 and the opening/closing body 10.
Therefore, the waterproofing device 30 ′ can more effectively prevent rainwater and the like from entering the gap s between the side frame member 21 and the opening/closing body 10 .

In addition, in the fitting device B shown in Figure 4, as a particularly preferred example, the entire covering portion 32 and the insertion portion 31' are formed from an elastic material, but it is sufficient for at least the base end side of the insertion portion 31' of this waterproofing device 30 to be formed from an elastic material.
Specifically, it is possible to adopt an embodiment in which only the surface layer on the base end side of the insertion portion 31' is made of an elastic material, and the other portions are made of a hard material.
According to this example, the elastic portion on the base end side of the insertion portion 31' is in close contact with the side frame members 21 and the opening/closing body 10 located on both sides thereof, so that good waterproof performance can be obtained.

Third Embodiment
The fitting device C shown in Figure 5 is similar to the fitting device A in that waterproofing devices 30 (or 30') are attached to the gap s between the leading end of the opening/closing body 10 and the side frame member 21, the gap s between the trailing end of the opening/closing body 10 and the side frame member 22, the gap s between the upper end of the opening/closing body 10 and the upper frame member 23, and the gap s between the lower end of the opening/closing body 10 and the lower frame member 24.
In other words, the waterproof devices 30 (or 30 ′) are attached between the four ends of the opening/closing body 10 and the opposing inner surfaces of the frame bodies 20 .
In addition, a waterproofing device 30 (or 30 ′) is attached to the gap s between the trailing end of the opening/closing body 10 and the side frame member 22 , other than the portion having the hinge 25 .

Therefore, according to the fitting device C, all of the gaps s around the opening/closing body 10 can be watertightly sealed from the outdoor side by the waterproofing device 30 (or 30'), thereby further improving the waterproofing performance.
In particular, even if water accumulates on the outdoor side of the opening/closing body 10 and the water level rises, causing part or all of the door and window device C to become submerged, the covering portion 32 of each waterproofing device 30 (30') is subjected to water pressure and comes into close contact with the frame body 20 and the opening/closing body 10, thereby providing good water-stopping performance.

<Fourth embodiment>
The fitting device D shown in Figure 6 is a double-leaf door device (swing door) in which the opening and closing bodies 10, 10' on both the left and right sides can be opened and closed (sometimes called a double-leaf door), and the gap s between the left and right opening and closing bodies 10, 10' is covered with a waterproofing device 30.

One opening/closing body 10 has a configuration similar to that of the above-mentioned door and window device A.
The other opening/closing body 10' has a cross-sectional shape that is symmetrical to the opening/closing body 10, and has a receiving portion 11' on its door end side that receives the opening/closing body 10 when closed. The door tail side of this opening/closing body 10' is pivotally supported on the side frame member 21 via a hinge 25.
The door-front end of this opening/closing body 10' is an opposing surface 10a' with a gap s between it and the door-front end 10a of the opening/closing body 10.

The receiving portion 11' protrudes toward the opening/closing body 10' from the indoor portion of the door-end side end of the opening/closing body 10'. An elastic airtight material 26 is attached to this receiving portion 11' in the vertical direction. This elastic airtight material 26 is pressed against the corner portion of the indoor side of the opening/closing body 10 (see Figure 6).

In this fitting device D, the waterproofing device 30 has its insertion portion 31 inserted into the gap s, the detachable portion 33 adhered to the outdoor side of the opening/closing body 10, and one half 32a of the covering portion 32 closely contacted with the outdoor side of the opening/closing body 10'.

Therefore, with the building fixture device D having the above-described configuration, even if the hinge 25 of the receiving portion 11' is damaged, the waterproofing device 30 can prevent water from entering the gap s between the opening/closing body 10 and the opening/closing body 10' from the outdoors.
Furthermore, even if there is a step between the left opening/closing body 10' and the right opening/closing body 10, the half portion 32a elastically bends and comes into close contact with both opening/closing bodies 10, 10', thereby effectively preventing water from entering.
Moreover, even when the waterproof equipment 30 is worn, both the opening/closing body 10 and the opening/closing body 10' can be opened and closed.

In addition, in the above-mentioned fitting device D, it is possible to replace the waterproofing device 30 with the waterproofing device 30' (see Figure 4), or to provide the waterproofing device 30 (or 30') in each of the gaps on all four sides of the opening and closing bodies 10, 10' in the same manner as in the above-mentioned fitting device C (see Figure 5).

<Other Modifications>
According to the above embodiment, the waterproofing equipment 30 (30') is provided on the outdoor side to prevent water generated on the outdoor side from entering the indoor side through the gap s, but as another example, the waterproofing equipment 30 (30') can be provided on the indoor side to prevent water generated on the indoor side from flowing through the gap s to the outdoor side. In other words, the water intrusion side can be the indoor side.

Furthermore, according to the above embodiment, as a particularly preferred aspect, the waterproof device 30 (30') is attached to the opening/closing body 10 side, but as another example, it is also possible to attach the waterproof device 30 (30') to the frame body 20 side (or the opening/closing body 10' side).
In this case, the detachable portion 33 is provided on the side frame member 21 (or the opening/closing body 10'), which is the member on the side of the opposing surface 21a (or 10a') relative to the end of the opening/closing body 10.
That is, for example, a detachable portion 33 is provided on the back side of one half 32a of the waterproofing device 30, and this detachable portion 33 is adhered to the visible surface of the side frame member 21. The other half 32b of the waterproofing device 30 does not have the detachable portion 33, and the dimension in the width direction is appropriately set (shorter than shown) so that the other half 32b does not bend elastically in response to the opening and closing operation of the opening-closing body 10 and does not interfere with the opening and closing operation of the opening-closing body 10.

In the illustrated example, the waterproof device 30 (30') is applied to a hinged door as a particularly preferred embodiment, but as an example other than the illustrated example, the waterproof device 30 (30') can be applied to a door device that opens and closes by rotating an opening and closing body, such as a folding door device, a balanced door device, or a window device that opens and closes by rotating an opening and closing body.
As another example, in a sliding door device or a sliding door type window device, a waterproofing device 30 (30') can be provided to cover the gap between the door body (opening/closing body) and the side frame member facing the door body in the closed state.

Furthermore, the present invention is not limited to the specific configuration described above, and can be modified as appropriate without departing from the spirit and scope of the present invention.
