Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in fittings configured to bring the tight material and the fin portion provided on the frame material into contact with the stile material as described above, the contact between the fin portion and the stile material affects the contact state between the tight material and the stile material, and there is a concern that the watertightness and airtightness between the frame material and the stile material may be impaired. That is, depending on the influence of molding errors, assembly errors, etc., there is a possibility that the contact state between the stile material and the tight material becomes excessive while the contact state between the tight material and the stile material becomes too small, and there is a concern that the basic functions of the fittings may be impaired.

[0005] In view of the above circumstances, an object of the present invention is to provide a fitting capable of improving heat insulation properties without impairing watertightness and airtightness.

Means for Solving the Problems

[0006] In order to achieve the above object, the fitting according to the present invention includes a frame body and a shoji door disposed so as to be openable and closable with respect to the frame body. At least one of the frame members constituting the frame body and the stile members constituting the shoji door is provided with a tight material that seals between them when the shoji door is disposed in the closed position with respect to the frame body. The frame member and the stile member each have a resin molded portion formed of resin, and a groove portion that forms a semi-closed space is provided in a portion surrounded by the frame member, the stile member, and the tight material when the shoji door is disposed in the closed position with respect to the frame body so as to open into the indoor space in the resin molded portion.

Effects of the Invention

[0007] According to the present invention, since a groove portion that opens into the indoor space and forms a semi-closed space is provided between the frame member and the stile member, it is possible to improve the heat insulation performance. Moreover, between the frame member and the stile member, only the tight material abuts, and there is no possibility that the abutting state of the tight material becomes too small due to the formation of the groove portion, and there is no concern that the watertightness and airtightness are impaired.

Further, the resin frame portion 46 is in a state where the finding surface facing the room of the groove forming fin portion 46c is located on the same plane as the finding surface facing the room of the resin engaging portion 45d.

[0028] The upper frame 21, the lower frame 22, and the left and right vertical frames 23 configured as described above are assembled into a four-sided unit, and the edge portion of the panel 25 is supported via a sealing material S3 between the respective panel support wall portions 41d, 43c, 45b and the four-sided pressing edge 40, thereby constituting the shoji 20. This shoji 20 is supported by the frame body 10 so as to be openable and closable by interposing a link mechanism 1 called a friction stay between the metal frame portion 41 of the upper frame 21 and the metal frame portion 30 of the upper frame 11 and between the metal frame portion 43 of the lower frame 22 and the metal frame portion 32 of the lower frame 12, respectively. When the shoji 20 is arranged in the closed position with respect to the frame body 10, the shoji 20 is held in the closed position by the above-described locking device (not shown) being engaged. In the state where the shoji 20 is arranged in the closed position, as shown in FIGS. 2 and 3, the upper seal member S0 provided on the upper frame 11 abuts against the upper frame 21, and the seal members S2 provided on the left and right vertical frames 23 abut against the corresponding vertical frames 13, respectively.

[0029] On the indoor side, a series of seal members S1 attached to the wall portions 30b, 32b, 34b of the frame body 10 per door are in contact with the finding surfaces facing the interior of the respective metal frame portions 41, 43, 45 of the upper frame 21, the lower frame 22, and the left and right vertical frames 23. Therefore, it is possible to prevent the entry of outdoor water such as rainwater and outdoor air into the interior. In particular, in the embodiment, the seal member S1 does not contact the resin frame portions 42, 44, 46 and contacts only the metal frame portions 41, 43, 45 with higher molding accuracy. Moreover, there is no other contact portion between the frame body 10 and the shoji 20 at the portion where the seal member S1 abuts. For this reason, it is possible to press-contact the seal member S1 without gaps, which is more advantageous in terms of the watertightness and airtightness between the frame body 10 and the shoji 20. In addition, in the upper frame 21, the lower frame 22, and the left and right vertical frames 23, since the groove-formed fin portions 31f, 33f, 35f on the inner peripheral side of the seal member S1 are arranged along the finding direction, the seal member S1 is in a situation where it is difficult to be visually recognized from the outside, which is also advantageous in terms of the appearance quality.

[0030] On the other hand, when the shoji 20 is arranged in the closed position, a groove portion 50 that opens to the indoor space side is secured around the four sides between the frame body 10 and the shoji 20. That is, between the upper frame 11 and the upper frame 21, the groove-formed fin portion 31f provided on the resin frame portion 31 and the groove-formed fin portion 42c provided on the resin frame portion 42 face each other at positions where a gap is secured, and a groove portion 50 that opens to the inner peripheral side is formed in the portion surrounded by the seal member S1, the groove-formed fin portion 31f, and the groove-formed fin portion 42c. Similarly, between the lower frame 12 and the lower frame 22, the groove-formed fin portion 33f provided on the resin frame portion 33 and the groove-formed fin portion 44c provided on the resin frame portion 44 face each other at positions where a gap is secured, and a groove portion 50 that opens to the inner peripheral side is formed in the portion surrounded by the seal member S1, the groove-formed fin portion 33f, and the groove-formed fin portion 44c. Between the vertical frame 13 and the vertical frame 23, the groove-formed fin portion 35f provided on the resin frame portion 35 and the groove-formed fin portion 46c provided on the resin frame portion 46 face each other, and a groove portion 50 that opens upward is formed in the portion surrounded by the seal member S1, the groove-formed fin portion 35f, and the groove-formed fin portion 46c.

[0031] Therefore, when assembling the shoji 20, since the panels 25 are arranged on the metal frame main body parts 41A, 43A, and 45A and then the resin frame parts 31, 33, and 35 do not interfere when attaching the pressing edge 40, the work becomes easier. Also, at that time, it is possible to look into the seal member S1 through the groove part 50. As a result, it becomes possible to accurately adjust the amount of crushing of the seal member S1, which is more advantageous in terms of watertightness and airtightness.

[0032] Here, in the present embodiment, as the groove part 50, when the shoji 20 is arranged in the closed position, the opening width along the expected direction is less than 10 mm, and the depth dimension along the finding direction with respect to the opening width is configured to be large. That is, the groove part 50 forms a semi-closed space between the shoji 20 and the frame body 10 respectively. The semi-closed space corresponds to the "groove or cavity with a small cross-section (semi-closed cavity)" defined in 6.4.1 of JIS A 2102-2:2011 6.4 "Ventilated cavity". Therefore, the heat insulation property of the indoor space equipped with this fitting is improved, and for example, even when the outdoor temperature is low, it is possible to suppress the situation where its influence reaches the indoor.

[0033] In addition, in the above-described embodiment, a vertical sliding window is exemplified, but as long as the shoji opens and closes with respect to the frame body, it can also be applied to other window types of fittings. Also, although an example is shown in which the frame material constituting the frame body and the frame material constituting the shoji each have a metal molded part and a resin molded part, it is sufficient if it has at least a resin molded part. Furthermore, although the groove part that becomes a semi-closed space is provided on all four sides, the groove part does not necessarily have to be provided on all four sides.

[0034] Also, in the above-described embodiment, since the groove part is provided so as to open to the inner peripheral side, even if the height position of the shoji is displaced with respect to the frame body, there is no possibility of causing a situation where the dimensions of the groove part are changed. However, the groove part may be provided so that the expected direction becomes the depth. Furthermore, although the tight material is provided on the frame body side, the tight material may be provided on the shoji side.

[0035] As described above, the fitting according to the present invention includes a frame body and a shoji door that is disposed so as to be openable and closable with respect to the frame body. At least one of the frame members constituting the frame body and the stile members constituting the shoji door is provided with a tight material that seals between them when the shoji door is disposed in the closed position with respect to the frame body. The frame member and the stile member each have a resin molded portion formed of resin. When the shoji door is disposed in the closed position with respect to the frame body, a groove portion that forms a semi-closed space is provided in the portion surrounded by the frame member, the stile member, and the tight material so as to open into the indoor space in the resin molded portion. According to the present invention, since a groove portion that opens into the indoor space and forms a semi-closed space is provided between the frame member and the stile member, it is possible to improve the heat insulation performance. Moreover, between the frame member and the stile member, only the tight material abuts, and there is no fear that the abutting state of the tight material becomes too small due to the formation of the groove portion, and there is no concern that the watertightness and airtightness are impaired.

[0036] Further, the present invention is characterized in that, in the fitting described above, the frame member and the stile member are each configured to have a metal molded portion formed of metal and the resin molded portion. According to the present invention, since a member having a metal molded portion is applied as the frame member and the stile member, it is advantageous in terms of rigidity.

[0037] Further, the present invention is characterized in that, in the fitting described above, the tight material is provided between the metal molded portion of the frame member and the metal molded portion of the stile member. According to the present invention, since the tight material is provided between the frame member and the stile member between the metal molded portions, it is less likely to be affected by secular change and thermal deformation, and the watertightness and airtightness can be ensured over a long period of time.

[0038] Further, in the fitting according to the present invention, the shoji screen has a panel supported between a pressing edge provided on the indoor side of the frame member, and the resin molding portion is attached to a portion facing the interior of the room on the pressing edge, and the groove portion is opened between the resin molding portion attached to the pressing edge and the resin molding portion of the frame member. According to the present invention, since the groove portion is formed between the resin molding portion attached to the pressing edge and the frame member, even when the pressing edge is attached with the shoji screen in the closed position, it does not interfere with the frame member, and the work can be easily carried out.

[0039] Further, in the fitting according to the present invention, the frame body has upper and lower horizontal frames and left and right vertical frames, the shoji screen has upper and lower horizontal frames and left and right vertical frames, and the groove portions are respectively provided between the upper and lower horizontal frames and the upper and lower horizontal frames and between the left and right vertical frames and the left and right vertical frames. According to the present invention, it is possible to improve the heat insulation property without impairing the watertightness and airtightness on the four sides.

[0040] Further, in the fitting according to the present invention, the groove portion is configured to open to the inner peripheral side, the tight material is provided on a finding surface facing the outside of the room in the metal molding portion of the frame member, and the finding surface facing the interior of the room facing the tight material in the frame member and the finding surface constituting the groove portion are located on the same plane. According to the present invention, since the finding surface facing the interior of the room of the frame member is flat, water generated in the room can be stored in the groove portion in the lower frame, which is advantageous in terms of drainage.

[0041] Further, in the fitting according to the present invention, the finding surface facing the outside of the room where the tight material is provided in the frame member and the finding surface constituting the groove portion are located on the same plane. According to the present invention, the tight material can be easily visually recognized with the shoji screen in the closed position, and the work of adjusting the tight material to have a desired amount of crushing can be easily and accurately carried out.
