Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water drain hole cover which is attached by covering water drain holes formed in a fitting frame of various fittings for opening and closing openings of buildings such as openable windows and doors,
In particular, it can be used for buildings such as the upper and lower floors of a building where the environment such as wind pressure is different at each location.

[0002]

BACKGROUND ART Conventionally, a lower frame of a fitting frame (window frame, etc.) of a fitting such as a window or a door has a gap between a door (screen etc.) of the fitting and a frame (window frame) of the fitting, and a glass of the shoji screen. A drain hole for draining rainwater that has entered between the caulking material for supporting the glass and ensuring the watertightness to the outside is formed.
In this drain hole, as disclosed in Japanese Utility Model Laid-Open No. 1-62491 or Japanese Patent Laid-Open No. 5-79257,
A cover was attached to prevent rainwater from being blown into the fittings through the drain holes due to wind or the like.

That is, conventionally, a water drain hole cover (see Japanese Utility Model Laid-Open No. 1-62491) is generally used in which a mounting hole is formed near the water drain hole and is attached to the outdoor side of the hole. Since a hole for mounting must be formed separately from the hole and the alignment and construction are complicated, a drain hole cover that is directly engaged with the water drain hole and is attached to the outdoor side thereof (Japanese Patent Laid-Open No. 5-79257). Japanese patent publication, especially FIG. 2) has been proposed.

By the way, in a high-rise building such as a building, the wind pressure is different between the upper and lower floors, and rainwater is easily blown through the water drain holes especially in the upper floors where the wind pressure is large. Therefore, the conventional outdoor cover is not sufficient. In some cases, it was necessary to place a cover on the indoor side of the drainage hole. Further, depending on the shape and type of the fitting frame to which the cover is attached, it may not be possible to attach the cover to the outside of the water drain hole, and in some cases it is necessary to attach the cover only to the inside of the water drain hole.

[0005]

However, these three conventional covers (a cover attached only to the outdoor side of the drainage hole, a cover attached only to the indoor side, and a cover attached to both the indoor and outdoor sides) respectively Different shapes and mounting methods, especially when using multiple types of covers on the upper and lower floors of one building such as a building, the number of types of cover products becomes large and the management becomes complicated, and the mounting methods are different, There was a problem that it was difficult to master the installation work, and the installation workability deteriorated. In addition, the conventional cover often had welding and screwing,
These have a problem that the mounting work is complicated and the workability is poor, and also when the cover is removed for inspection of the drainage hole, the removing work is complicated and the workability is poor.

The object of the present invention is to make it possible to compose three types of covers (a cover attached to the outdoor side of the drain hole, a cover attached to the indoor side and a cover attached to the outdoor side) with two types of covers. The number of types of covers can be reduced, which allows various types of cover management (production, inventory,
(Transportation to the construction site) is easy, the mounting method can be standardized for each cover, and easy mounting work can be performed.
It is to provide a drain hole cover that can improve the mounting workability.

[0007]

SUMMARY OF THE INVENTION The present invention is a water drain hole cover for covering a water drain hole formed in a fitting frame, the cover having an engaging portion engageable with the water drain hole, The other side across the hole (outside the water drain hole or the other side inside)
A cover with a locking portion, which includes a locking portion capable of locking the engaging portion of the locked side cover provided on the outside of the water drain hole or on one side of the inside of the water drain hole. It is characterized by.

The drainage hole cover of the present invention can be engaged with the engaging portion of the engaging portion cover when used in combination with the engaging portion cover, and can be used alone. Is provided with a locked side cover having an engaging portion that can be engaged with the water drainage hole of the fitting frame on the opposite side of the cover with the locking portion sandwiching the water drainage hole. It may be configured by two covers, a cover with a locking portion.

At this time, the locking portion of the cover with the locking portion is
A relative position in the indoor / outdoor direction of the locking portion with respect to the locked side cover when the locked side cover is engaged with the locking portion,
When the locked side cover is used alone and is engaged with the drain hole, the relative position in the indoor / outdoor direction of the engaged portion of the water drain hole with respect to the locked side cover is the same. It is preferable that the object to be formed and to which the locked side cover is attached has the same mounting structure regardless of whether it is the drain hole or the cover with the locking portion.

In the present invention, depending on the environment of the place where the drain hole cover is provided, that is, the conditions such as the size of the wind pressure, the shape of the fitting frame, and the appearance, either the cover with the locking portion or the locked side cover is used. Only one of them may be attached, or the cover with the engaging portion and the cover on the engaged side may be combined and attached. Further, as an engaging portion of each cover, there is an engaging protrusion that is fitted into the drain hole or the like and locked to the peripheral edge of the drain hole, and the peripheral edge of the drain hole is sandwiched between this engaging protrusion and the cover body side. It is preferable that the structure be attached in such a manner.

[0011]

In such a drain hole cover of the present invention,
To attach only one of the cover with the locking portion and the cover on the locked side to the drainage hole, the engaging portion of each cover is fitted into the drainage hole and engaged. At this time, instead of welding or screwing, it suffices to fit the engaging part of the cover into the drainage hole to engage with each other, so that each cover is easily attached to the drainage hole part and the workability is improved. Can be easily removed, and maintainability is improved.

Further, in order to attach both the cover with the locking portion and the cover on the locked side to the drainage hole, the engaging portion of the cover with the locking portion is fitted into the drainage hole to be engaged, and then the locking portion. The engaging portion of the locked side cover is fitted and engaged with the engaging portion of the attached cover. At this time, since the locked side cover is attached by engaging with the locking part-equipped cover, it is not necessary to form a hole for mounting the locked side cover in the fitting frame, and the locking part-equipped cover is Since only the drainage holes to be attached need to be formed, no extra processing is required on the fitting frame side. Further, the locked side cover has the same mounting structure when engaged with the water drain hole and when engaged with the cover with the locking portion, and no extra processing is required for each cover. Further, even when the covers are attached in combination, since the engaging portions are simply engaged, the attachment method is the same as the case where the covers are attached individually, and the attachment work is simplified and the workability is improved.

Further, regardless of whether the cover with locking portion and the cover on the locked side are used individually or in combination, two kinds of common covers can be used, and additional processing for combining each cover is also possible. Because it is unnecessary
Easy to use. Therefore, with two types of covers, that is, the cover with the locking portion and the cover on the locked side, it is possible to easily realize a three-mode cover (a cover only on the outdoor side of the drainage hole, a cover on the indoor side, and a cover on both the indoor and outdoor sides). It also facilitates management of production and inventory.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. This embodiment is a vertical cross-sectional view of the inward opening window 1 shown in FIG.
As shown in FIG. 2, the water outside hole 16 formed in the window frame 2 of the inward opening window 1 has an outdoor side cover 20 that is a cover with a locking portion on both the outdoor side and the indoor side, and a chamber that is a locked side cover. The inner cover 30 is attached.

The inward opening window 1 is composed of a window frame 2 which is a fitting frame and a shoji 3 which is a door. The window frame 2 is formed by assembling an upper frame 5 and a lower frame 6 and left and right vertical frames (not shown) into a rectangular frame shape. The upper frame 5, the lower frame 6 and the vertical frame are provided on the outdoor side in order to improve heat insulation performance.
A and 6A are divided into indoor frames 5B and 6B, and are connected via a heat insulating material 7 formed of resin such as EPDM (ethylene propylene terpolymer).

The shoji 3 is formed by assembling an upper frame 8 and a lower frame 9 and left and right vertical frames (not shown) in a rectangular frame shape. These upper frame 8, lower frame 9 and vertical frame are the above-mentioned window frame 2
Similarly, to increase the heat insulation performance, the outside frames 8A, 9
A and the frames 8B and 9B on the indoor side are divided, and are connected via a heat insulating material 7.

The shoji 3 has a glass 10 disposed inside, and the glass 10 has a caulking material 11 at the periphery thereof.
It is attached to the shoji 3 by being held by the upper frame 8, the lower frame 9 and the vertical frame via 12. This shoji 3 has one vertical frame rotatably connected to the window frame 2 and is configured to be opened and closed on the indoor side with the vertical frame as a rotation axis.

EPDM (ethylene propylene terpolymer) is attached to each of the upper frame 8, the lower frame 9 and the vertical frame of the shoji 3 so as to prevent rainwater from entering the window frame 2 when the shoji 3 is closed. An airtight material (airtight material, AT material, seal material) 13 for a rain barrier, which is formed of a resin or the like), is attached along the upper frame 8, the lower frame 9, and the vertical frame so as to be continuous for four rounds. Further, EPDM (ethylene propylene terpolymer) which prevents rainwater from entering the window frame 2 when the shoji 3 is closed is also provided on the indoor side portions of the upper and lower frames 8, 9 and the vertical frame of the shoji 3. Airtight material (airtight material, AT material, sealing material) for wind barrier formed of resin, etc. 14
Are attached so as to be continuous for four rounds along the upper frame 8, the lower frame 9, and the vertical frame.

In the lower frame 9 of the shoji 3, there is a drain hole 15 opened vertically to drain rainwater that has entered the shoji 3 from between the glass 10 and the caulking materials 11, 12.
The lower frame 9 is formed at least at one location, preferably at a plurality of locations, in the longitudinal direction (the direction orthogonal to the paper surface of FIG. 1). Further, in the lower frame 6 of the window frame 2, a drainage hole 16 opened in the indoor side direction and opened to the outdoor side is provided, and a drainage hole 16 is formed in the longitudinal direction of the lower frame 6 (in the plane of FIG. (Orthogonal direction)
It is formed at least at one place, preferably at a plurality of places.

As shown in FIGS. 2 and 3, in the drainage hole 16 portion, the outdoor side cover 20 and the indoor side cover 30 are made of an appropriate resin such as nylon 6 (polyamide 6).
And are attached. The outdoor cover 20 is shown in FIG.
As shown in FIG. 5, the wall surface 21 is continuous from the upper surface to the vertical surface through the curved surface, and the side surface 22 is continuously integrated with the wall surface 21. ,
Moreover, the lower surface is opened. Further, two engagement portions 23 are provided upright inside the wall surface 21 (inside the room), and a tip portion of the engagement portion 23 is inclined outward with respect to the indoor-outdoor direction in a horizontal plane. Engaging projection 24 with surface 24A
Are formed.

The inside of the engaging portion 23 (the other engaging portion 23
The locking portion 25 is provided so as to project on the side facing the side). When the indoor cover 30 is engaged with the outdoor cover 20, the locking portion 25 causes the indoor cover 30 to drain the water hole 16 of the window frame 2.
So that the same mounting structure as when directly engaging with
In the state where the outdoor side cover 20 is engaged with the drainage hole 16, the dimension in the indoor / outdoor direction from the indoor side surface of the window frame 2 to the outdoor side surface of the locking portion 25 is equal to the thickness dimension of the window frame 2. It is set to match.

As shown in FIGS. 3 to 5, the indoor cover 30 is integrally formed with an upper surface 31, an indoor rear surface 32, and a side surface 33 having an opening on the indoor side. From each side surface 33, wall surfaces 34 parallel to the rear surface 32 are formed in a direction toward each other, and two engaging portions 35 project from the wall surfaces 34 toward the outdoor side. Similar to the engaging portion 23, an engaging protrusion 36 having an inclined surface 36 </ b> A that is inclined outward with respect to the indoor / outdoor direction in the horizontal plane is formed at the tip of the engaging portion 35.

The indoor side cover 30 serves to make it difficult for rainwater to flow into the indoor side by changing the flow direction of the rainwater flowing in from the side of the drain hole 16 toward the direction along the rear surface 32 by 90 degrees, and functions as a so-called baffle. It is a cover. If necessary, a felt (wool sponge) 37 is arranged between the rear surface 32 and the wall surface 34 of the cover 30 so that rainwater can be more reliably prevented from entering.

In order to attach the outdoor side cover 20 and the indoor side cover 30 in this embodiment, first,
The drainage hole 16 of the window frame 2 is formed in accordance with the width dimension of the two engaging portions 23 of the outdoor side cover 20. Next, drain hole 1
The engaging portion 23 of the outdoor side cover 20 is inserted into 6 from the outdoor side. As the engaging part 23 is fitted and inserted, the engaging part 23 is provided with the inclined surface 2
When 4A comes into contact with the peripheral edge of the water drain hole 16, it is gradually pushed inward (in a direction in which the two engaging portions 23 approach each other). Then, when the inclined surface 24A passes through the drainage hole 16, the engaging portion 23 returns to the outside (the direction in which the two engaging portions 23 separate from each other), and the engaging protrusion 24 and the side surface 22 of the engaging portion 23.
The window frame 2 around the drainage hole 16 is sandwiched between and, and the outdoor side cover 20 is engaged with and attached to the drainage hole 16.

Next, from the indoor side to the indoor side cover 3, the locking portion 25 of the outdoor side cover 20 engaged with the drain hole 16 is inserted.
The zero engagement part 35 is inserted. With the insertion of the engaging portion 35,
The engaging portion 35 is pushed inward (the direction in which the two engaging portions 35 approach each other) when the inclined surface 36A contacts the locking portion 25. Then, when the inclined surface 36A passes through the locking portion 25, the engaging portion 35 returns to the outside (the direction in which the two engaging portions 35 separate from each other), and the engaging projection 36 of the engaging portion 35 and the side surface 33 drain water. The window frame 2 in the hole 16 portion and the locking portion 25 are sandwiched, and the indoor cover 30 is attached by being engaged with the outdoor cover 20.

When the two types of covers 20 and 30 are attached to the water drain holes 16 in this manner, the rainwater that has entered the inside opening window 1 flows into the indoor side cover 30 through the drain holes 15 and the indoor side cover 30. From the opening formed in the side surface 33 of the outer wall 32 through the rear surfaces 32 and 34, the flow direction is changed in the outdoor direction along the engaging portion 35, and the water drain hole 16 is used to open the outdoor side cover 2.
It flows to the 0 side and is drained from the opened lower surface of the outdoor side cover 20. On the other hand, even if it is provided in a place such as the upper floor of the building where the wind pressure is strong, since the drain hole 16 is covered with the outdoor cover 20, rainwater is hardly blown into the drain hole 16 from the outdoor side. Even if rainwater enters from the lower surface of the cover 20, the wind and rain blown from the water drain holes 16 collide with the rear surface 32 of the indoor cover 30 to stop the flow, that is, the indoor cover 30 acts as a baffle. Intrusion of rainwater into the window 2, that is, inside the window is prevented. In particular, when the felt 37 is arranged, the rainwater that has infiltrated permeates the felt, so that the infiltration of rainwater from the drain hole 16 is reliably prevented.

Next, the two types of covers 20 and 3 of this embodiment will be described.
The case where 0 is provided independently will be described. When only the outdoor side cover 20 is attached, as shown in FIGS. 6 and 7, the width dimension of the drain hole 16 is set to the width dimension between the engaging portions 23 of the outdoor side cover 20 (the same width as when the covers 20 and 30 are attached). This drain hole 1 is made according to the dimensions)
The engaging portion 23 is fitted into the connector 6. Then, as in the case described above, the engaging portion 20 is gradually inserted along the inclined surface 24A, and if the engaging protrusion 24 is pushed in until it passes through the drainage hole 16 portion, the engaging protrusion 24 and the side surface 22 drain water. The periphery of the hole 16 is sandwiched, and the outdoor side cover 20 is engaged with and attached to the drain hole 16.

Further, as shown in FIGS. 8 and 9, for example, a drainage hole 52 is formed in a window frame 51 of the outer opening window 50, and a shoji 53 is provided.
In the case where it is arranged close to the water drain hole 52 and the cover of the water drain hole 52 cannot be provided outside the room, etc., only the indoor side cover 30 is attached. Indoor side cover 30
For installation, adjust the width dimension of the drain hole 52 to the indoor side cover 30.
The engaging portions 35 are formed in accordance with the width dimension between the engaging portions 35 (smaller than the drainage holes 16), and the engaging portions 35 are fitted into the drainage holes 52. Then, like the case of the outdoor cover 20,
If the engaging portion 35 is gradually pushed along the inclined surface 36A of the engaging protrusion 36 and is pushed until the engaging protrusion 36 passes through the drainage hole 52 portion, the peripheral edge of the drainage hole 52 is formed by the engaging protrusion 36 and the side surface 33. And the indoor side cover 30 is engaged with and attached to the drain hole 52.

The outdoor side cover 20 and the indoor side cover 30 have a drain hole 1 for attaching the covers 20 and 30.
It is selected and attached according to the environment of the place where 6, 52 are provided. That is, when the wind pressure on the lower floors is low and rainwater does not blow into the drain holes 16 and 52 so much, the outdoor side cover 20 that is easy to install and remove and easy to maintain may be selected and installed. On the other hand, even if the amount of rainwater blown in is small, if the cover does not want to be exposed to the outside due to its design (design), or as shown in FIGS. If it cannot be attached, the indoor cover 30 may be selected and attached. Furthermore, when the wind pressure is strong on the upper floors of the building or the like and rainwater is easily blown from the water drain holes 16 and 52, the outdoor side cover 20 is provided.
In order to prevent the rainwater from being blown in more reliably, the felt 37 may be built in the indoor cover 30.

According to this embodiment, the following effects can be obtained. That is, regardless of whether the outdoor side cover 20 and the indoor side cover 30 are attached in combination or individually, the engaging portions 23 and 35 are attached to the drainage holes 16 and 52 and the engaging portions 23 and 35 at the time of attachment. It is only necessary to engage with the portion 25, and as compared with the case of attaching by screwing or welding, the attaching and detaching work can be performed easily, and the attaching workability and the maintenance workability can be improved. In particular, since the mounting work can be made common when the covers 20 and 30 are used individually and when they are combined, the work procedure is easier to learn as compared with the conventional case where the mounting methods are different. The property can be further improved.

Also, the outdoor side cover 20 and the indoor side cover 3
The size of the water drain hole 16 and the indoor side cover 20 to be used can be shared between the case of using the combination of 0 and the outdoor side cover 20 alone, that is, whether the indoor side cover 30 is added or not. There is no difference, and even when the indoor side cover 30 is used alone, the size of the water drain hole 52 is different from that of the water drain hole 16, and since the outdoor side cover 30 can use a common one, each cover 20 can be used. , 3
0 can be easily used properly. Especially the drain hole 1
It is easy to change the size of 6, 52, otherwise, just select the covers 20, 30 to be used, for example to combine both covers 20, 30, to attach each cover 20, 30 Since it is not necessary to perform processing such as providing each of the holes in the window frame 2, it is a very simple operation, and only the outdoor side cover 20, only the indoor side cover 30, and the covers of three modes when both covers 20, 30 are used. Can be realized. Therefore, each drain hole 16,5
2, the optimum cover can be easily attached, rainwater can be prevented from being blown from the drainage holes 16 and 52, and rainwater that has entered the window 2 can be reliably drained from the drainage holes 16 and 52. It is possible to ensure watertightness and airtightness.

Further, since the covers of the above three modes can be realized by the two types of covers 20 and 30, the types of covers to be manufactured are different from those in the case where different types of covers are used in the respective cover structures as in the conventional case. It is possible to reduce the production cost by reducing the production efficiency and reduce the manufacturing cost, and it is possible to easily manage the inventory and the transportation of the cover product to the site. Therefore, particularly when a plurality of aspects of the cover structure are provided in one building (building or the like), the covers 20 and 30 prepared for combination and the cover 2 prepared for individual use are provided.
0 and 30 can be diverted to each other, and elastic management can be performed. Further, when the outdoor side cover 20 is used alone, since the drainage hole 16 is partially closed by the locking portion 25 and becomes narrower, it is possible to further prevent the blowing of rainwater, and the locking portion 25 is provided. The watertightness can be improved as compared with the case where it is not provided.

The present invention is not limited to the above-described embodiments, but includes modifications and improvements as long as the object of the present invention can be achieved. For example, in the above-described embodiment, the outdoor side cover 20 is the cover with the locking portion and the indoor side cover 30 is the locked side cover.
As shown in FIG. 10, the outdoor side cover 60 is a locked side cover, the outdoor side cover 70 is a cover with a locking portion, and the engaging portion 71 of the indoor side cover 70 is engaged with the drainage hole 16 of the window frame 2. And the engaging portion 72 protruding from the engaging portion 71,
It may be attached by engaging the engaging portion 61 of the outdoor side cover 60.

Further, in the above embodiment, the engaging portion 25 is provided on the engaging portion 23, but as shown in FIG. 11, the engaging portion 81 and the engaging portion 81 are provided on the engaging portion cover such as the outdoor side cover 80. Alternatively, the locking portion 82 may be formed separately. In this case, the indoor cover 9
The engaging portion 91 of the locked side cover such as 0 is set in accordance with the position of the engaging portion 82. However, it is easier to manufacture when the engaging portion 25 is formed in the engaging portion 23 as in the above-described embodiment, and the width of the engaging portion 35 of the locked side cover engaged with the engaging portion 25 is formed. The dimensions can be made close to the width of the engaging portion 23, and the width of the drain holes 16 and 52 set by these widths can be changed in a small range, so that the drain holes 16 and 52 can be easily formed. .

Further, the engaging portions 23, 35, 61, 71,
The shapes and structures of 81 and 91 are not limited to those of the above-described embodiment and modified examples, and may be set appropriately in practice. However, as in the above embodiment, the engaging portions 23, 35, 61, 71, 8
Forming 1, 91 has an advantage that each cover 20, 30, 60, 70, 80, 90 can be easily attached only by fitting it into the drain holes 16, 52 and the like.

Further, each cover 20, 30, 60, 70,
The shapes, materials, structures, and the like of 80 and 90 are not limited to those in the above-described embodiment, and may be set as appropriate for implementation. further,
Contrary to the above-described embodiment, the mounting order when both the locking portion-equipped cover and the locked side cover are mounted is the reverse of the above-described embodiment, and the locked side cover (indoor side cover 30) is placed in the drainage hole 16 portion first. Then, thereafter, the cover with the locking portion (the outdoor side cover 20) may be fitted and inserted so that the locking portion 25 and the engaging portion 35 are engaged with each other while engaging the drain hole 16. The procedure may be appropriately set in consideration of which side of the indoor or outdoor side the cover with the locking portion and the cover on the locked side are arranged. Further, the fitting to which the present invention is applied is not limited to the inner opening window 1 and the outer opening window 50 as in the above-described embodiment, but various types of windows, doors, etc. having various drainage holes 16 are formed. It can be widely applied to joinery.

[0037]

According to the drainage hole cover of the present invention as described above, the cover with the locking portion is provided with the locking portion for locking the engaging portion of the locked side cover. The mounting work can be shared between the case with the attached cover and the cover on the locked side, and the case with both covers combined.
In addition, since the work only needs to fit and insert the respective engagement portions into the water drain holes or the locking portions, the work of attaching and detaching the cover can be simplified and the workability can be improved. Also, with two types of covers, a cover with locking part and a cover on the locked side,
It is possible to configure a cover of three modes (a cover that is attached only to the outdoor side of the drain hole, a cover that is attached only to the indoor side, and a cover that is attached to both the indoor and outdoor sides of the water drain hole). Management (production, inventory, transportation to the construction site) can be performed easily.
