Description

[Technical Field]

[0001] This invention relates to a building fixture with an escape hatch. [Background technology]

[0002] In traditional wooden houses, toilets were considered relatively safe during earthquakes because they were enclosed on all four sides by pillars. However, in modern houses, toilets are often constructed using a partition method. As a result, the strength is not always sufficient, and there is a risk that the door frame may warp during an earthquake, preventing the door from opening. In this way, if doors or other fixtures become deformed or damaged by an earthquake, or if an obstacle is placed in front of them, preventing them from opening, a problem arises in which people could be trapped in the room partitioned by the fixtures.

[0003] To address these problems, for example, Patent Document 1 proposes a door with an emergency exit, aimed at enabling escape from the room when the door becomes stuck. In the door described in Patent Document 1, the closing member is struck and the frame holding the closing member is destroyed, thereby removing the closing member and enabling escape through the emergency exit. However, the door described in Patent Document 1 has the problem that it is not easy to escape because force must be applied to destroy the members, and there is a risk of injury to the person escaping. In addition, with the door described in Patent Document 1, since the frame and other members are destroyed during the escape, there is the problem that it is difficult to repair the door.

Figure 8(a) illustrates a water injection method, and Figure 8(b) illustrates a method for removing the blocking member. [Modes for carrying out the invention]

[0017] Embodiments of the present invention will be described below with reference to the drawings. Figure 1(a) is a front view of the door with an escape hatch 1 in this embodiment, and Figure 1(b) is a rear view of the door with an escape hatch 1 in this embodiment. Figure 2 is an exploded perspective view of the door with an escape hatch 1 in this embodiment. Hereafter, the front side of the door with an escape hatch 1 will also be referred to as the "outdoor side," and the rear side of the door with an escape hatch 1 will also be referred to as the "indoor side."

[0018] As shown in Figures 1(a) and 1(b), the door with an escape hatch 1 in this embodiment comprises a door body 10 and a closing member 20. As shown in Figure 2, an adhesive 30 is interposed between the door body 10 and the closing member 20, and the door body 10 and the closing member 20 are joined by the adhesive 30 in a manner that allows for water-peelability. The door with an escape hatch 1 in this embodiment is a door attached to a door frame 100 by a hinge 110, but is not limited to this, and may be a sliding door, a partition, etc. Note that the door frame 100 is not shown in Figure 2. Similarly, the door frame 100 is not shown in Figures 3 to 6, which will be described later. Also, in Figure 1(b), the words "Emergency" are printed on the surface of the cover 18, which will be described later.

[0019] The door body 10 is not particularly limited, but can be made of, for example, a metallic material such as aluminum or stainless steel, a wooden material such as plywood, or a glass material. The door body 10 has a rectangular frame portion 12 at the bottom (downward along the Z-axis in the figure). The frame portion 12 forms an escape opening 11 that penetrates the door body 10. The escape opening 11 is normally closed by a closing member 20. In an emergency, when the door with an escape opening 1 cannot be opened or closed, the escape opening 11 is opened by removing the closing member 20 and used to escape from the room separated by the door with an escape opening 1.

[0020] Figure 3 is an enlarged perspective view of the frame portion 12 in this embodiment. In Figure 3, the closing member 20 and the adhesive 30 are omitted. As shown in Figure 3, the frame portion 12 has a stepped portion 13 that protrudes toward the inside of the escape opening 11 and has a thickness smaller than the thickness of the door body 10. The stepped portion 13 is formed to surround the escape opening 11, and the opening area of ​​the escape opening 11 is defined by the stepped portion 13. The stepped portion 13 is the part of the frame portion 12 that comes into contact with the adhesive 30 and is the part that is joined to the closing member 20 via the adhesive 30. The stepped portion 13 has a joining surface 13a that is substantially perpendicular to the penetrating direction of the escape opening 11 (Y-axis direction in the figure), and the adhesive 30 is placed on this joining surface 13a. Also, as shown in Figure 1(b), the stepped portion 13 is provided at the interior side end in the thickness direction of the frame portion 12.

[0021] As shown in Figure 3, a water channel 14 is formed in the joint surface 13a facing the closing member 20 at the stepped portion 13. The water channel 14 is used to supply water to the adhesive 30 that joins the door body 10 and the closing member 20. In this embodiment, the water channel 14 is formed to pass to the side and below the exit opening 11. In this embodiment, one water channel 14 is formed, but it is not limited to this, and multiple water channel 14 may be provided. As long as the water passing through the water channel 14 can come into contact with the adhesive 30, the arrangement, width, length, and other configurations of the water channel 14 are not particularly limited.

[0022] Figure 4 is a lateral cross-sectional view along the line IV-IV in Figure 1(a), and Figure 5 is a plan cross-sectional view along the line VV in Figure 4. As shown in Figures 4 and 5, a water inlet 15 is provided above the frame portion 12 of the door body 10. The water inlet 15 communicates with the water guide groove 14. Also, as shown in Figure 5, the water inlet 15 is formed to face the adhesive 30 located above the exit opening 11. In this embodiment, the water inlet 15 is provided inside the door body 10, but the position of the water inlet 15 is not particularly limited as long as it communicates with the water guide groove 14. For example, the water inlet 15 may be provided on the outer surface of the door body 10.

[0023] As shown in Figure 4, a storage space 16 is formed inside the door body 10, above the water inlet 15. The storage space 16 communicates with an opening 17 formed on the interior side. The opening 17 is covered with a removable cover 18. In this embodiment, the cover 18 is made of adhesive tape and is fixed to the door body 10 in a removable state, but the form of the cover 18 is not particularly limited thereto. The presence of the cover 18 prevents the ladle 60 (described later) placed in the storage space 16 from falling out of the door with escape opening 1 through the opening 17 when the door with escape opening 1 is opened or closed under normal circumstances. In an emergency, the storage space 16 is opened through the opening 17 by peeling off and removing the cover 18. Below the storage space 16 is a water inlet 15. For this reason, the water guide groove 14 provided in the stepped portion 13 of the frame portion 12 communicates with the outside through the storage space 16, the water inlet 15, and the opening 17. Furthermore, it is not necessary for cover 18 to be provided.

[0024] Figure 6 is a front view illustrating the water supply to the water channel 14. In Figure 6, the closing member 20 and the adhesive 30 are not shown. In the building fixture 1 with an escape opening in this embodiment, water is supplied to the water channel 14 from the water inlet 15 by pouring water into the storage space 16 from the opening 17, and as shown in Figure 6, it is possible to fill the water channel 14 with water. In Figure 6, the area enclosed by the dashed line indicates that the water channel 14 is filled with water.

[0025] As shown in Figure 1(b), a ladle 60 is placed in the storage space 16. The ladle 60 only needs to have a concave structure that can scoop water, and its structure is not particularly limited. As shown in Figure 4, the storage space 16 is provided with a holding part 161 and a protruding part 162 for holding the ladle 60, but the method of holding the ladle 60 is not particularly limited. The ladle 60 can be removed from the door with an exit opening 17 and used to supply water to the water channel 14. In this embodiment, a ladle 60 is placed in the storage section 16, but it is not particularly limited to this, and any object that can scoop and supply water is acceptable. For example, a watering can, a cup, etc. may be placed instead of a ladle 60.

[0026] As shown in Figure 1(a), a packing 50a is provided on the front edge of the frame portion 12. Also, as shown in Figure 1(b), a packing 50b is provided on the back edge of the frame portion 12 (the edge of the stepped portion 13). The materials constituting the packings 50a and 50b are not particularly limited, but examples include rubber materials such as acrylonitrile butadiene rubber, fluororubber, silicone rubber, and urethane rubber; and resin materials such as fluororesin, polyethylene, polypropylene, and polyamide.

[0027] The blocking member 20 is a member that closes the exit opening 11. Under normal circumstances, the exit opening 11 is closed by the blocking member 20, and the door with an exit opening 1 functions as a typical door.

[0028] Figure 7 is a plan cross-sectional view taken along the line VII-VII in Figure 1(b). As shown in Figure 7, the closing member 20 comprises a main body portion 21 and a joint portion 22. The main body portion 21 is the part that is inserted into the opening defined by the stepped portion 13 in the escape opening 11. The joint portion 22 is the part to which adhesive 30 is placed and which is joined to the frame portion 12 via the adhesive 30. The thickness of the joint portion 22 is approximately the same as the thickness of the door body 10 minus the thickness of the stepped portion 13, and the overall thickness of the closing member 20 is approximately the same as the thickness of the door body 10. In other words, the closing member 20 is held in place by the door body 10 without protruding from the door body 10. Therefore, the design of the door with escape opening 1 is not impaired by the closing member 20.

[0029] The blocking member 20 is inserted into the escape opening 11 from the front side, and is held in place by the door body 10 by the joint portion 22 being joined to the frame portion 12 with adhesive 20. As will be described later, in an emergency, after the adhesive 30 is peeled off with water, the blocking member 20 is pushed out from the inside to the outside, thereby opening the escape opening 11 and allowing escape through the escape opening 11. The blocking member 20 only needs to be capable of blocking the escape opening 11 and making it impassable, and the structure of the blocking member 20 is not particularly limited. In this embodiment, the stepped portion 13 of the frame portion 12 is provided at the inside end, and the blocking member 20 can be removed toward the outside, but the configuration of the frame portion 12 and the blocking member 20 is not particularly limited. For example, the stepped portion 13 of the frame portion 12 may be provided at the outside end, and the blocking member 20 can be removed toward the inside. With such a structure, it becomes possible to rescue a person trapped inside from the outside. Specifically, in nursing facilities and care facilities, when a person trapped inside a room is unable to escape on their own, a rescuer outside the room can push the blocking member 20 from the outside to the inside to open the escape opening 11, thereby rescuing the trapped person to the outside.

[0030] Furthermore, in this embodiment, the frame portion 12 is provided with a stepped portion 13, a water guide groove 14 is formed on the joint surface 13a of the stepped portion 13, and adhesive 30 is placed on the joint surface 13a. However, the structure of the frame portion 12 and the position of the adhesive 30 are not particularly limited to these. For example, the frame portion 12 may not be provided with a stepped portion 13, and the water guide groove 14 may be formed on the inner surface of the frame portion 12, that is, the surface facing the center of the escape opening 11, and the adhesive 30 may be placed on this inner surface. As a result, the direction of movement of the blocking member 20 is not restricted by the stepped portion 13, and the blocking member 20 can be removed in either the indoor or outdoor direction. Therefore, a person trapped inside the room can push the blocking member 20 outwards to escape, and a rescuer outside can push the blocking member 20 inwards to open the escape opening 11 and rescue the person trapped inside the room.

[0031] The adhesive 30 consists of a water-removable adhesive composition. The adhesive composition contains a cationic group-containing polymer having cationic groups in its polymer chain and water, wherein the content of the cationic group-containing polymer is 55% by weight or more and 95% by weight or less, and the content of water is 5% by weight or more and 45% by weight or less. The cationic group-containing polymer may be a polymer having cationic groups in its main chain, or a polymer having cationic groups in its side chains, or a polymer having cationic groups in both its main chain and side chains.

[0032] The cationic group contained in the cationic group-containing polymer used in the present invention is not particularly limited, but examples include cationic groups containing a nitrogen atom, phosphorus atom, sulfur atom, or oxygen atom as the central atom. Among these, a cationic group containing a nitrogen atom as the central atom is preferred from the viewpoint of electromagnetic shielding performance. Preferred cationic structures are the following structures (I) or (II), specifically including ammonium, iminium, imidazolium, pyridinium, etc. Furthermore, it is preferable that the substituents of the cationic group consist of two or more groups with two or more atoms bonded to them. In addition, the cationic group-containing polymer used in the present invention may have anionic groups in addition to cationic groups in the polymer chain, for example, it may have a betaine structure. [ka]

[0033] The cation group-containing polymer used in the present invention preferably has polar atoms other than cation groups in addition to the cation group. By having such polar atoms, the positive charge of the cation can be neutralized, improving the dissociation properties of the anion, thereby further enhancing the electromagnetic shielding performance, as well as improving transparency and flexibility. Examples of such polar atoms include oxygen atoms and nitrogen atoms. Examples of groups having such polar atoms include, but are not particularly limited to, ether bonds, ketone groups, carboxyl groups, hydroxyl groups, amine groups, amide bonds, urethane bonds, and urea bonds. The imidazolium structure has another nitrogen atom in addition to the cationic nitrogen atom in the imidazolium ring, and such another nitrogen atom can also be said to be a polar atom other than a cation group.

[0034] Examples of cationic group-containing polymers include addition polymers of vinyl compounds, polyethers, polyethyleneimines, and polyoxazolines, which have cationic groups in their side chains, and ionenes, epichlorohydrin-amine condensates, and polyamide polyamine epichlorohydrins, which have cationic groups in their main chains. These may have any other substituents, or some hydrogen atoms may be substituted with halogen atoms such as fluorine. Furthermore, cationic group-containing polymers may be copolymerized with structural units derived from monomers that do not have cationic groups, in addition to structural units that have cationic groups, and the pH may be adjusted by introducing structural units derived from acidic monomers or structural units derived from basic monomers.

[0035] The cation group-containing polymer used in the present invention has a cation group in the polymer chain, and the counter anion for such a cation group is not particularly limited, but examples include imides such as fluorosulfonylimide, bistrifluoromethylsulfonylimide, and bispentafluoroethylsulfonylimide; halogens such as chlorides and bromides; tetrafluoroboric acid, hexafluorophosphate, dicyanoamide, tetracyanoborate, carbonic acid, alkyl carbonate, triflate, perchloric acid, nitric acid, sulfuric acid, alkyl sulfuric acid, sulfonic acid, phosphoric acid, and alkyl phosphoric acid; however, it is not particularly limited.

It may also take the form of a polycyclic structure in which two or more rings are fused.

By containing the cationic group-containing polymer having cationic groups in the polymer chain and water within the above-mentioned specific range, the adhesive composition can achieve excellent adhesiveness and strength, and can be easily peeled off after use.

[0105] The content of the cationic group-containing polymer in the adhesive composition used in the present invention is 55% by weight or more and 95% by weight or less, preferably 60% by weight or more and 90% by weight or less, and more preferably 65% ​​by weight or more and 85% by weight or less.

If the content of the cationic group-containing polymer is too low, the strength will be insufficient, and if the amount of water is too low, the adhesive properties will be insufficient. The content of the cationic group-containing polymer and water may be within the above ranges in the usage environment, but it is desirable that they be within the above ranges at least in an environment of 25°C and 50% RH. It is desirable to measure the content of the cationic group-containing polymer and water after leaving them for a long period of time (for example, about one week) to allow the condition to stabilize, taking into account their hygroscopic properties.

[0106] The adhesive composition used in the present invention may contain components other than cationic group-containing polymers and water, and may contain salts such as sodium chloride and potassium chloride. The inclusion of salts can improve ionic conductivity and spoilage resistance. Furthermore, the adhesive composition used in the present invention may contain surfactants, anionic polymers, amphoteric polymers, etc., and may also be pH-adjusted by adjusting the type of monomer used or by using a buffering agent.

The fibrous material may be a single fiber, a twisted yarn, a coil, a woven fabric, or a nonwoven fabric.

[0108] In this embodiment, the adhesive 30 is formed by gelling the above-mentioned adhesive composition into a sheet-like molded body. Because the adhesive 30 is made of the above-mentioned adhesive composition, it is swellable with water or soluble in water. In this embodiment, because the adhesive 30 made of the above-mentioned adhesive composition is used, the door body 10 and the closing member 20 are joined in a state that can be peeled off with water. That is, under normal circumstances, the door body 10 and the closing member 20 are joined by the adhesive 30, but the door body 10 and the closing member 20 can be easily separated by supplying water to the adhesive 30. By supplying water to the water guide groove 14 through the water inlet 15 of the door body 10, the water comes into contact with the adhesive 30 that is in contact with the surface 13a, and the adhesive 30 swells or dissolves, making it possible to separate the door body 10 and the closing member 20.

[0109] Figures 8(a) and 8(b) illustrate an escape method using the door with an escape hatch 1 in this embodiment. By installing the door with an escape hatch 1 in this embodiment as a toilet door, in the event of an emergency, a person trapped inside the toilet can escape using the following method. First, the person escaping peels off and removes the cover 18, then takes out the ladle 60 housed in the containment space 16 from the opening 17 and scoops up water stored in the toilet's water tank or the like. Next, as shown in Figure 8(a), the person escaping pours the water into the containment space 16 from the opening 17. As a result, as shown in Figure 6, water is supplied to the water channel 14 from the water inlet 15 at the bottom of the containment space 16. The water supplied to the water channel 14 comes into contact with the adhesive 30 and swells or dissolves it. As a result, the adhesive 30 is peeled off, and the bond between the door body 10 and the closing member 20 is released. Next, as shown in Figure 8(b), the person escaping opens the escape opening 11 by pushing the blocking member 20 from the inside to the outside. This allows the person escaping from inside to escape outside through the escape opening 11.

[0110] As described above, in the door with an escape hatch 1 of this embodiment, the closing member 20 can be removed by peeling off the adhesive 30 using water, and there is no need to apply force when removing the closing member 20. Therefore, escape can be performed easily and safely. Furthermore, in the door with an escape hatch 1 of this embodiment, the closing member 20 can be removed without damaging it during escape, and the closing member 20 can be reattached to the door body 10 using the adhesive 30 to close the escape hatch 11. Therefore, the door with an escape hatch 1 of this embodiment is easy to repair after escape.

[0111] In addition, in this embodiment, the door with an escape hatch 1 is joined to the door body 10 by adhesive 30 alone, eliminating the need for other members or mechanisms to fix the door with the escape hatch 20 to the door body 10. Therefore, the door with an escape hatch 1 in this embodiment is easy to manufacture and reduces manufacturing costs.

[0112] In the door with an escape hatch 1 of this embodiment, the frame portion 12 of the door body 10 is provided with a stepped portion 13, and adhesive 30 is placed on the stepped portion 13. Therefore, the contact area between the door body 10 and the adhesive 30 can be increased, and the bonding strength between the door body 10 and the closing member 20 can be increased.

[0113] The embodiments described above are provided to facilitate understanding of the present invention and are not intended to limit it. Therefore, each element disclosed in the above embodiments is intended to include all design modifications and equivalents that fall within the technical scope of the present invention.

[0114] For example, in the above embodiment, a ladle 60 is placed in the containment space 16, but a container storing water may be placed in place of the ladle 60. By placing a container storing water, the door with an escape hatch 1 can also be used as a door for a room without a water supply source. That is, in an emergency, water can be supplied from the water storage container placed in the containment space 16 to the water channel 14 via the water inlet 15, thereby separating the door body 10 from the sealing member 20.
