<Specific embodiment>
Next, specific embodiments having the above-mentioned features will be described in detail with reference to the drawings.

The fitting device 1 shown in FIG. 1 comprises a frame body 10 formed in a rectangular frame shape from multiple frame members including a trailing edge frame member 11, a door body 20 that opens and closes an opening within the frame body, a multi-axis hinge 30 that rotates the door body 20 open and close and moves it in the door thickness direction on the trailing edge side of the door body 20 in the closed state, a first elastic member 40 provided on the trailing edge frame member 11 of the frame body 10, and a second elastic member 50 provided on the trailing edge portion of the door body 20.

The frame body 10 is configured as an integrated rectangular frame with an opening in the center, and includes a trailing edge frame member 11 that faces the trailing edge of the door body 20 in the closed state, a leading edge frame member 12 that faces the leading edge of the door body 20, and an upper frame member 13 and a lower frame member 14 that face the upper and lower ends of the door body 20, respectively. This frame body 10 is fixedly attached to an opening in the structure of a building or the like.

The trailing edge side frame member 11 is a member that is continuous and elongated in the vertical direction, and is formed in a generally frame-like cross section as shown in FIG.
The trailing edge side frame member 11 has a trailing edge facing portion 11a facing the trailing edge of the door body 20 in the fully closed state, and a groove portion 11b facing the trailing edge-proximal portion of the surface of the door body 20 in the fully closed state in the closing direction.
The trailing edge side frame member 11 has a cross section that is approximately L-shaped from the trailing edge opposing portion 11a to the groove portion 11b, and this L-shaped portion is fitted into the corner portion where the back surface and the trailing edge surface of the door body 20 in the fully closed state intersect (see Figures 2(b) and 3).

The tail end facing portion 11a is a flat surface that is rectangular in plan view and faces continuously in the vertical direction to the tail end surface of the door body 20 in the fully closed state.

As shown in Figure 2, the groove portion 11b is formed with a concave cross section consisting of a surface that continues from the door end facing portion 11a in the front direction, a bottom surface that is bent from said portion in the front direction, and a surface that protrudes from the bottom surface and leaves a space between it and the door end facing portion 11a.
The groove portion 11b is continuous over the entire length of the trailing edge frame member 11 in the vertical direction, with its opening facing the closing direction side surface of the door body 20 in the fully closed state.

The door body 20 is configured as a rectangular plate when viewed from the front and has a predetermined thickness. According to the illustrated example, the door body 20 is composed of a front plate 21 and a back plate 22 spaced apart in the thickness direction and fixed to a plurality of frames 23 positioned between them.
The end of the door body 20 on the door front side is a flat surface that is rectangular in plan view and continues over the entire length in the vertical direction.

In the illustrated embodiment, the hinge 30 is a biaxial hinge.
This hinge 30 comprises one support part 31 fixed to the front surface 11c of the trailing edge frame member 11, the other support part 32 attached to the trailing edge side of the surface of the door body 20, and a link member 33 pivoted at one end and the other end to the support parts 31, 32, respectively, and supports the door body 20 so that it can be rotated open and closed and can move linearly in the front direction.
It should be noted that the hinge 30 may have three or more axes as long as they function in a similar manner.

The first elastic member 40 is a member that is elastically pressed against the door body 20 when fully closed, thereby closing the gap between the frame body 10 and the door body 20.
This first elastic member 40 comprises a base 41 that fits into the groove portion 11b of the door end side frame member 11, a pressed portion 42 connected to the door body opening direction side of this base 41, and a first protrusion portion 43 and a second protrusion portion 44 that protrude from the outer surface of this pressed portion 42.
The first elastic member 40 is integrally formed from an elastic material such as an elastomer resin or synthetic rubber.

The base 41 is formed in a generally rectangular cross section with a hollow portion (see FIG. 5), and is continuous over the entire vertical length of the trailing edge frame member 11. On the outer surface of the base 41, a number of retaining pieces 41a are provided at intervals in the projection direction, which are elastically pressed against the inner surface of the groove 11b to prevent the base 41 from coming out.

The pressed portion 42 is formed in a hollow cylindrical shape in cross section with an internal space surrounded by a peripheral wall portion 42a. A receiving portion 42b is provided in the internal space to receive the inner surface of the peripheral wall portion 42a when the peripheral wall portion 42a is depressed. The peripheral wall portion 42a and the receiving portion 42b are continuous over the entire length of the trailing edge frame member 11 in the vertical direction.
The receiving portion 42b is a protrusion that protrudes from the base portion 41 in the opening direction of the door body, and in the illustrated example, is formed in a mountain-like cross section.
The pressed portion 42 having the above-mentioned structure is pressed in the front direction by the trailing edge portion of the rear surface of the door body 20 when the door body 20 is closed, and elastically contracts.

The first protruding piece 43 is a member that protrudes from the outer surface of the pressed part 42 and continues in the vertical direction, and is pressed against the rear surface of the door body 20 over its entire vertical length.

The second protruding piece 44 protrudes from the outer surface of the pressed part 42 and is a continuous member that extends over the entire vertical length of the trailing edge frame member 11, and is formed in a rectangular shape in plan view that is elongated in the vertical direction.

The second protruding piece 44 comes into surface contact with the trailing edge facing portion 11 a of the trailing edge side frame member 11 .
When the door body 20 is closed, this second protrusion portion 44 is sandwiched and compressed between the second elastic member 50 on the door body 20 side and the door end opposing portion 11a over the entire vertical length of the door body 20.

The vertical length of the second protruding piece 44 is set to be at least longer than the vertical length of the door body 20 .
In addition, the dimension L of the second protrusion 44 in the forward direction is set so that this second protrusion 44 overlaps with the door tail opposing portion 11a, and in the illustrated example, is set to more than half the thickness dimension of the door body 20 (see Figure 2 (b)).

The reference numeral 49 in the figure denotes a spacer that is provided in one or more positions between the base 41 and the bottom surface of the groove 11b to adjust the amount of protrusion of the first elastic member 40. The spacer 49 is integrally molded so as to be detachable from the base 41, but it may also be a separate member.

The second elastic member 50 is formed in a long rectangular shape in a plan view so as to cover substantially the entire surface of the end portion of the door body 20, and covers the end portion of the door body 20 over substantially the entire length in the door thickness direction.
The second elastic member 50 is formed of a closed-cell foam made of elastic synthetic resin, which has particularly good watertightness. In this embodiment, ethylene propylene diene rubber (EPDM) is used as the synthetic resin.
The second elastic member 50 is adhered to the end portion of the door body 20 so as to be in surface contact with the end portion.

The leading edge frame member 12 is formed symmetrically to the trailing edge frame member 11. An elastic member 60 is fitted into the groove 12a of the leading edge frame member 12 over the entire length in the vertical direction.
The elastic member 60 is the first elastic member 40 without the first protrusion 43 and the second protrusion 44, and like the first elastic member 40, has a base 61, a pressed portion 62, a receiving portion 62b, etc.
As another example, the elastic member 60 can be replaced with the first elastic member 40 with the left and right reversed.

In addition, the upper frame member 13 and the lower frame member 14 are each provided with an elastic member (not shown) that is substantially similar to the one on the door end side and extends over substantially the entire length in the viewing direction.

Next, the characteristic functions and effects of the fitting device 1 having the above configuration will be described in detail.
First, when the door 20 is in an open state, as shown in FIG. 2A, the first elastic member 40 and the second elastic member 50 are in an initial state in which they are not compressed and deformed.

In the fully closed position where the door body 20 almost closes the opening in the frame body 10, as shown in FIG. 2(b), the second elastic member 50 and the second protruding piece 44 are sandwiched in an overlapping state between the tail end of the door body 20 and the tail end facing portion 11a of the tail end side frame member 11.

After this, when the door body 20 is pushed in the forward direction, as shown in FIG. 3, the surface of the door body 20 facing the closing direction is pressed against the first protrusion 43, causing the first protrusion 43 to bend elastically, and further, the surface of the door body 20 facing the closing direction and the corner portion connected to said surface are pressed against the pressed portion 42, causing the pressed portion 42 to bend elastically.

Then, the inner surface of the peripheral wall portion 42a of the pressed portion 42 comes into contact with the receiving portion 42b. This prevents the door body 20 from being pushed in too far and coming into contact with the edge of the groove portion 11b, which would cause the airtightness and watertightness due to the elasticity of the pressed portion 42 to be lost.

On the other hand, at the leading edge of the door body 20, the rear surface of the door body 20 is pressed against the pressed portion 62 of the elastic member 60 (see FIG. 4). At this time, just like at the trailing edge, the inner surface of the peripheral wall of the pressed portion 62 abuts against the receiving portion 62b, suppressing the amount of pressing of the door body 20.

In addition, on the top and bottom sides of the door body 20, the back surface of the door body 20 is pressed against an elastic member (not shown) in the same manner as the door end side.

Therefore, according to the fitting device 1 having the above-mentioned configuration, it is possible to improve the airtightness and watertightness around the door body 20, and in particular to prevent a decrease in airtightness and watertightness at the door end side.
Therefore, according to the fitting device 1, good water-stopping performance can be obtained even in cases where a large water pressure is applied to the outdoor side due to a flood or the like.

<Other Modifications>
In the above embodiment, the above-mentioned waterproof structure is configured in a single-door type fitting device 1, but as another example of the present invention, the above-mentioned waterproof structure can also be applied to a double-door type fitting device.
In this case, for example, the above-mentioned waterproof structure may be constructed by providing the first elastic member 40 and the second elastic member 50 on the end sides of the main door 20' and the sub door 20" that make up the double-door fixture.
In this other example, the mating portion of the parent door 20' and the child door 20'' is configured as shown in FIG.
The child door 20'' has a groove 24' at its door edge which overlaps with the back surface of the parent door 20' from the closing direction side. An elastic member 60 is fitted into this groove 24' so as to be pressed against the back surface of the parent door 20'.

In the above embodiment, the first elastic member 40 is formed from a closed-cell foam resin as a particularly preferred embodiment, but as another example, the first elastic member 40 can also be formed from an open-cell foam resin.

In addition, in the above embodiment, a biaxial hinge is used, but other examples of these hinges include single-axis hinges such as flag hinges, flat hinges, and pivot hinges, and hinges with three or more axes.

As another particularly preferred example, a multi-axis hinge set 30'' can be used in place of the hinge described above (see FIG. 7).
This hinge set 30″ comprises a vertical axis hinge 30a″ (in the illustrated example, a flag hinge) having a rotating member 32″ that rotates about a vertical axis and is attached to a base member 31″, and a horizontal axis hinge 30b″ attached to the rotating member 32″.
The horizontal axis hinge 30b'' comprises a first axis member 33'' that constitutes a horizontal rotation axis, a link member 34'' having one end side rotatably supported relative to the first axis member 33'' and the other end side hanging down, and a second axis member 35'' that is rotatably supported on the other end side of the link member 34'' and is aligned below the first axis member 33''.
The first shaft member 33 ″ has a connection base portion 33 b ″ that can be connected to the rotating member 32 ″, and the second shaft member 35 ″ has a fixing portion 35 b ″ that can be fixed to the door body 20 .
According to a fitting device using this hinge set 30'', the wobbling of the fitting in the thickness direction, which occurs when a conventional biaxial hinge is used, can be suppressed by the weight of the door body 20, etc.

Although not shown in Figure 7, a first elastic member 40 and a second elastic member 50, etc. are provided between the trailing edge side of the door body 20 and the trailing edge side frame member 11, in the same manner as in the above-mentioned building fixture devices 1 and 2.
In addition, in FIG. 7, the symbol 20a″ denotes a through hole. This through hole 20a″ penetrates the end surface of the door body 20 and the second elastic member 50, etc., and its inner edge does not interfere with the connection base 33b″, etc. during operation of the hinge 30b″.

Furthermore, the above-mentioned waterproof structure using the first elastic member 40 and the second elastic member 50 etc. can be applied not only to waterproof door devices and watertight doors, but also to windows that open and close by pivoting, shutter devices including overhead doors, and other fittings and devices.
For example, when the waterproof structure is applied to a shutter device, the shutter curtain is made up of a plurality of panels (or slats) that rotate relative to one adjacent panel above and below, and therefore the waterproof structure can be provided between these adjacent panels.

Furthermore, the present invention is not limited to the above-mentioned embodiments, and can be modified as appropriate without departing from the spirit and scope of the present invention.
