DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the joint structure and the door and window of the present invention will be described with reference to the accompanying drawings.

Fig. 1 is an external view showing a state in which a door and window (i.e., a door and window according to an embodiment of the present invention) to which a joint structure of a profile according to an embodiment of the present invention is applied is viewed from the indoor side. The door and window exemplified herein is a so-called double sliding window in which the left and right sashes 20 are provided in the opening frame 10, and the two sashes 20 are opened and closed in the left-right direction with respect to the opening frame 10.

The opening frame 10 is formed by forming a rectangular opening formed by combining the upper frame 11, the lower frame (first profile) 12, and the pair of left and right vertical frames 13 and 14 into a peripheral frame. The upper frame 11, the lower frame 12, and the pair of right and left vertical frames 13, 14 are, for example, extruded metal profiles of aluminum or the like. The opening frame 10 is such that each of the upper frame 11, the lower frame 12, and the pair of left and right vertical frames 13 and 14 is attached to the body opening 2 of the body 1 formed on the home wall or the like along the opening edge thereof. .

The door sash 20 is such that the face material 25 is held inside by a frame in which the upper frame 21, the lower frame 22, and the pair of right and left vertical frames 23 and 24 are combined into a frame. The upper frame 21, the lower frame 22, and the pair of left and right vertical frames 23 and 24 are, for example, extruded metal profiles of aluminum or the like.

However, between the left end surface 12a of the frame 12 below the opening frame 10 constituting the door and window and the joint surface 13a on the lower side of the vertical frame (second shape, hereinafter also referred to as the left vertical frame) 13 on the left side, 2 map A sealing material 30 is interposed. Further, in the example of Fig. 2, only the left end surface 12a of the lower frame 12 and the joint surface 13a on the lower side of the left vertical frame 13 are shown, but in the above-mentioned door and window, at the right end surface 12b of the lower frame 12 and The joint surface 14a on the lower side of the vertical frame (hereinafter also referred to as the right vertical frame) 14 on the right side, the left end surface 11a of the upper frame 11 and the joint surface 13b on the upper side of the left vertical frame 13, and the right end of the upper frame 11 A sealing member 30 having the same configuration is also interposed between the surface 11b and the joint surface 14b on the upper side of the right vertical frame 14.

The sealing material 30 is a sheet formed of an elastic material such as a synthetic rubber material, and is attached to the joint surface 13a on the lower side of the left vertical frame 13. The sealing member 30 has a larger outer dimension than the left end surface 12a of the lower frame 12.

Further, as shown in FIG. 3, the swelling material 40 is applied to the surface of the sealing material 30. The swellable material 40 is composed of a superabsorbent polymer (SAP: Super Absorbent Polymer), and has a function of absorbing a large amount of water and gelling it, and retaining the water. Such a swelled material 40 is applied by covering the surface of the sealing material 30.

Further, when the upper frame 11, the lower frame 12, and the pair of right and left vertical frames 13 and 14 are combined into a peripheral frame, as shown in Fig. 4, the left end surface 12a of the lower frame 12 is joined to the sealing member 30 via the sealing member 30. The joint surface 13a on the lower side of the left vertical frame 13. At this time, the seal member 30 and the swelled material 40 interposed between the left end surface 12a and the joint surface 13a on the lower side of the left vertical frame 13 are compressed by the lower frame 12 to be deformed by being pressed by the lower frame 12. In addition, on the lower end surface 12b of the lower frame 12 and the lower side of the right vertical frame 14 Between the joint faces 14a, between the left end surface 11a of the upper frame 11 and the joint surface 13b of the upper side of the left vertical frame 13, and between the right end surface 11b of the upper frame 11 and the joint surface 14b of the upper side of the right vertical frame 14, The seal member 30 and the swelled material 40 are similarly compressed and deformed.

When the operation of providing the opening frame 10 having the joint structure as described above to the body opening 2 of the body 1 is performed, the lower frame 12 faces the left end surface 12a due to the conveyance method when the opening frame 10 is conveyed. The force is generated from the direction in which the joint surface 13a on the lower side of the left vertical frame 13 is disengaged, or the size of the element forming the body opening 2 or the like, and the lower frame 12 is from the left vertical frame 13 toward the left end surface 12a thereof. When a force is generated in the direction in which the lower joint surface 13a is disengaged, as shown in Fig. 5, a gap may be formed between the left end surface 12a of the lower frame 12 and the seal member 30 and the swelled material 40.

In detail, the sealing member 30 and the swellable material 40 are both composed of a resin material, and in particular, the sealing material 30 is composed of an elastic material. Therefore, when the lower frame 12 is detached from the left vertical frame 13, it may be due to its own Resilience returns to its original shape, which is the initial shape. However, when the left end surface 12a of the lower frame 12 is pressed for a long time and is compressed and deformed, even if the lower frame 12 is displaced in the direction away from the left vertical frame 13, the sealing member 30 and the swellable material 40 cannot be instantaneously restored by the restoring force. When the original shape is restored, it may take several days or more to restore the original shape by the restoring force, or it may not be restored to the original state. Therefore, the sealing member 30 and the swelled material 40 do not follow the displacement of the lower frame 12 and maintain their shape, and as a result, a gap is formed between the left end surface 12a of the lower frame 12.

When a gap is generated and water such as rainwater enters the gap, the joint structure is expanded as the swelled material 40 absorbs the water as shown in Fig. 6, so that the water can be prevented from passing through the gap, and as a result, it is ensured. Water stop performance.

According to the joint structure of the present embodiment described above, even if a gap is formed between the left end surface 12a of the lower frame 12 and the seal member 30 attached to the joint surface 13a of the left vertical frame 13, the seal member 30 is applied. The surface of the swelled material 40 swells by absorbing the water entering the gap, thereby suppressing the passage of water through the gap, thereby ensuring the water stopping performance, whereby even the left end surface 12a of the lower frame 12 faces the joint surface from the left vertical frame 13. The displacement of 13a in the direction of departure also makes the water stopping performance good.

The preferred embodiments of the present invention have been described above, but the present invention is not limited to the embodiments, and various modifications can be made.

In the above embodiment, the example in which the swelled material 40 is applied to the surface of the sealing material 30 has been described. However, in the present invention, as shown in Fig. 7, the sealing material 50 may contain a super absorbent resin (SAP). : Super Absorbent Polymer) is composed of a swellable material 60. In other words, the sealing material 50 may be formed into a sheet shape by mixing the swelling material 60 having a function of absorbing a large amount of water and retaining the water.

In the case where such a sealing material 50 is used, when the upper frame 11, the lower frame 12, and the pair of left and right vertical frames 13, 14 are combined into a peripheral frame, as shown in Fig. 8, the left end of the lower frame 12 is shown. The surface 12a is joined to the joint surface 13a on the lower side of the left vertical frame 13 via the sealing member 50. At this time, since it is pushed by the lower frame 12, it is disposed on the left end surface 12a and the left side. The seal member 50 between the joint faces 13a on the lower side of the vertical frame 13 is compressed by the lower frame 12 to be deformed. Further, between the right end surface 12b of the lower frame 12 and the joint surface 14a on the lower side of the right vertical frame 14, between the left end surface 11a of the upper frame 11 and the joint surface 13b of the upper side of the left vertical frame 13, and the upper frame The seal member 50 between the right end surface 11b of the 11 and the joint surface 14b on the upper side of the right vertical frame 14 is similarly compressed and deformed.

When the operation of attaching the opening frame 10 having the above-described joint structure to the body opening 2 of the body 1 is performed, the lower frame 12 is inclined from the left side to the left end surface 12a due to the conveyance method during the conveyance of the opening frame 10. The direction in which the joint surface 13a on the lower side of the frame 13 is disengaged generates a force, or because the dimensional error or the like of the elements constituting the body opening 2 causes the lower frame 12 to face the left end surface 12a from the lower side of the left vertical frame 13 When a force is generated in the direction in which the joint surface 13a is disengaged, as shown in Fig. 9, a gap may be formed between the left end surface 12a of the lower frame 12 and the seal member 50.

When a gap is generated and water such as rainwater enters the gap, the joint structure is as shown in FIG. 10, and the swelling material 60 contained in the sealing material 50 is located on the surface of the sealing material 50. The swelled material 60 absorbs the water and swells, and the water can be prevented from passing through the gap, and as a result, the water stopping performance can be ensured.

According to the joint structure having such a configuration, even if a gap is formed between the left end surface 12a of the lower frame 12 and the seal member 50 attached to the joint surface 13a of the left vertical frame 13, the swelling material contained in the seal member 50 is caused. 60 absorbing the water entering the gap and expanding, thereby suppressing the water passage When the gap is passed, the water stopping performance can be ensured, whereby even if the left end surface 12a of the lower frame 12 is displaced in the direction away from the joint surface 13a of the left vertical frame 13, the water stopping performance can be improved.

In the above-described embodiment and its modifications, the lower frame 12 is exemplified as the first profile, and the left vertical frame 13 is exemplified as the second profile. However, as described above, the present invention is not limited to the lower frame 12 and the left. The vertical frame 13 can be applied as long as it is a structure in which the end surface of one of the elongated profiles and the joint surface of the other profile are joined. That is, the frame members of the door sash 20 may be joined to each other.

In the above-described embodiment, the swelling material 40 is applied to the surface of the sealing material 30. However, in the present invention, the swelling material may be applied to the end surface of the first molding material as in the left end surface 12a of the frame 12 as follows.
