  However, in the gasket described in Patent Document 1, since the expected interval between the closely contacting portions and the expected interval between the ridges and between the seal ridges are set to be approximately the same, the tolerance dimension is large. In the case of supporting a material, there is a problem that sufficient water stoppage cannot be ensured or the mounting property to a face material is deteriorated. That is, since the tip of the close contact portion and the tip of the protrusion or seal protrusion are provided at substantially the same expected positions, when the face material is thin, the face material surface and the close contact portion are sufficiently close to each other. In the case where the water stoppage cannot be ensured and the face material is thick, the resistance of the ridges and the seal ridges is increased, so that the attachment to the face material becomes difficult. For this reason, if the expected interval between the close part and the ridges or seal ridges is set to a small value in order to ensure the water-stopping property, the wearability deteriorates. If the value is set to a large value, the water stoppage is lowered.

  An object of the present invention is to provide a gasket and a fitting capable of ensuring both sufficient water-stopping property and good mounting property.

The gasket of the present invention is a gasket that is attached to the edge of the face material and supports the face material with respect to the frame material, and has a bottom surface portion and a pair of side surface portions, and has a rubber-like elastic shape with a substantially U-shaped cross section. The pair of side surface portions are provided with first, second, and third protrusions that protrude toward the face material, facing each other, and the first protrusions are Formed at the open end of the side surface portion away from the bottom surface portion, the second ridge portion is formed at a position near the bottom surface portion in the side surface portion, and the third ridge portion is formed by the first and first ridge portions. Projecting toward the face material at two locations between the two ridge parts, and the two third ridge parts are formed to have inclined surfaces inclined to the sides away from each other. In an unmounted state, the prospective direction interval dimension (L1) between the tips of the first protrusions facing each other is It is set smaller than the prospective direction distance dimension (L2) between the tips of the second ridges facing each other (L1 <L2), and the prospective direction distance dimension (L2) between the tips of the second ridge parts is The first, second, and third protrusions are set smaller than the prospective direction distance dimension (L3) between the tips of the third protrusions facing each other (L2 <L3) and mounted on the face material. Among the strips, at least the first and second projections are in close contact with one and the other surfaces of the face material while being bent.

The gasket of the present invention is a gasket that is attached to the edge of the face material and supports the face material with respect to the frame material, and has a bottom face part and a pair of side face parts, and has a substantially U-shaped cross section. The pair of side surface portions are provided with first, second, and third protrusions that protrude toward the face material, respectively, and the first protrusions are The second protrusion is formed at a position near the bottom surface in the side surface, and the third protrusion is the first protrusion. And projecting toward the face material at two locations between the second projecting ridges, and the two third projecting ridges are formed to have inclined surfaces inclined to the sides away from each other. The opposing first and second protrusions are in close contact with one and the other surfaces of the face material while being bent, respectively. Together, the projecting lengths of the first and second ridges are such that the tightness between the first ridge and the face material is greater than the tightness between the second ridge and the face material. The protrusion length of the third protrusions facing each other is set so as to increase, and the closeness between the third protrusion and the face material is such that the second protrusion and the face material are in close contact with each other. It may be set so as to be smaller than the intimate strength of the head, or may be set so that the third protrusion is not in contact with the face material in the normal mounting state.

According to the present invention described above, the first, second, and third protrusions are formed on the side surface of the gasket, and at least the first and second protrusions of these are in close contact with the surface of the face material. In this way, it is possible to reliably prevent rainwater and the like from entering between the surface of the face material and the gasket, and to ensure water-stopping.
Further, the prospective direction interval dimension (L1) between the tips of the first protrusions is set to be smaller than the expectation direction interval dimension (L2) between the ends of the second protrusions (L1 <L2), or By setting the projecting length of the first and second ridges so that the intimate strength between the first ridge and the face material is larger than the intimate strength between the second ridge and the face material. In addition, it is possible to improve the wearability by reducing the frictional resistance with the face material by the second ridge portion while securing the water stoppage by the first ridge portion.
Furthermore, the prospective direction distance dimension (L3) between the tips of the third protrusions is set shorter than the prospective direction distance dimension (L2) of the second protrusions, or the protrusion length of the third protrusions. Is set so that the tightness between the third ridge and the face material is smaller than the tightness between the second ridge and the face material, or in the normal wearing state, Even if the first and second protrusions are deformed by the wind pressure acting on the face material in a strong wind, the first and second ridges are deformed while securing the face material so as not to contact the face material. The three protrusions can be in close contact with the face material to prevent the face material from moving, thereby ensuring water-stopping.

Accordingly, when the plate thickness dimension of the face material varies, that is, when the expected dimension of the face material is thin, the first and second protrusions follow to ensure water-stopping, and the expected dimension of the face material. When the thickness is thick, the third ridge portion is bent together with the first and second ridge portions, so that the water stoppage can be ensured.
At this time, as the face material, any panel body such as single plate glass, laminated glass, meshed glass, and multi-layer glass can be used, and in particular, multi-layer glass having a large tolerance of expected dimension (thickness dimension). In the case of using, it is possible to remarkably exhibit the effect that deterioration of the wearability can be prevented while securing water-stopping properties.
The gasket as described above is suitable for a sash window of a high-rise building (particularly a high-rise house) that requires high wind resistance and is required to have airtightness, sound insulation, and heat insulation.
In addition, the normal mounting state is a state in which the face material with the gasket attached is incorporated into a shoji fold, etc., and the face material is not moved or bent in the expected direction due to external force such as wind pressure. It is. That is, the state in which the gasket is bent as a result of external force such as wind pressure acting on the face material and the face material moving or bending in the expected direction is not a normal mounting state.

In the gasket of the present invention, the face material is a multi-layer glass formed by having a pair of indoor and outdoor glass panels and a sealing material interposed between the glass panels, and the bottom surface Preferably, the part is formed with a pair of fourth protrusions that respectively contact the end surfaces of the pair of glass panels in the multilayer glass.
According to such a configuration, as described above, the waterproof property and the wearability can be ensured even if the multilayer glass having a large thickness tolerance is used, and the fourth protrusion is the edge of the glass panel of the multilayer glass. , The sealing material of the multilayer glass and the bottom surface of the gasket are separated from each other, and a gap (space) is formed between them. As a result, even if rainwater or the like enters between the double-glazed glass and the gasket, the rainwater or the like does not touch the sealing material, and the moisture is transmitted to the hollow layer of the double-glazed glass by permeating the sealing material. Intrusion can be prevented.

Furthermore, in the gasket of the present invention, it is preferable that an opening is formed in the bottom surface portion.
According to such a configuration, even if rain water or the like enters between the face material and the gasket, the rain water or the like is quickly discharged from the opening and the rain water or the like comes into contact with the edge of the face material. Can be prevented. Therefore, especially when the face material is a double-glazed glass, it is possible to reliably prevent deterioration of the sealing material, clouding of the inner surface of the hollow layer, etc. by drying the gasket.

Moreover, it is preferable that the gasket of this invention is formed in the whole cyclic | annular form continuous along the four peripheral edge of the said face material.
According to such a configuration, a gasket made of a rubber-like elastic body is formed in an annular shape according to the size of the face material, and can be easily mounted on the four sides of the face material simply by attaching the gasket while extending it. In addition, since it is possible to make it difficult to remove the attached gasket, it is possible to improve the assemblability of the face material and the frame material.

  On the other hand, the joinery of the present invention is a joinery provided with a window frame and a shoji supported by the window frame, and the shoji is surrounded by upper and lower, left and right anchors, and these fences. A face material to be fitted, and a gasket according to any one of claims 1 to 5 that is attached to an edge of the face material and supports the face material with respect to the saddle material, The saddle member is formed to have a concave groove-shaped face material support part, and a fifth protrusion that is in close contact with the inner surface of the side wall of the face material support part is formed outside the side surface part of the gasket. It is characterized by that.

  According to the present invention, in accordance with the above-described effect of the gasket, the inner surface of the side wall of the face material support portion of the saddle material and the fifth protrusion of the gasket are in close contact, that is, the saddle material and the gasket are in point contact. With this configuration, it is possible to reduce the friction between the gasket and the saddle material when assembling the shoji that attaches the face material fitted with the gasket to the saddle material, and to improve the workability of the shoji assembly work. .

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The sliding window 1 is supported by a window frame 10 in which an upper frame 11, a lower frame 12, and left and right vertical frames 13 made of an aluminum extruded profile are formed on four sides, and can be slidably opened and closed inside the window frame 10. The indoor / outdoor pair of shojis 15 is provided. The window frame 10 is fixed to the building housing 2 such as a floor or a wall in the opening of the outer wall, and a window frame 3 is provided on the indoor side of the window frame 10.

  As shown in FIG. 3, the shoji 15 includes a multi-layer glass 19 as a face material inside an aluminum extrusion-shaped upper iron 16, a lower iron 17, and left and right vertical irons 18. It is configured by fitting. The pair of indoor and outdoor shojis 15 are overlapped and closed at the summoning section, and can be locked by a crescent provided on the vertical fence 18 inside and outside the summing section. Furthermore, the indoor and outdoor vertical fences 18 in the summoning section, between the upper fence 16 and the upper frame 11, between the lower fence 17 and the lower frame 12, and between the vertical fence 18 and the vertical frame 13 on the door side. An airtight material is provided between them, and the airtightness and watertightness of the sliding window 1 are ensured by these airtight materials.

Next, the support structure of the multilayer glass 19 in the shoji 15 of the sliding window 1 will be described in detail with reference to FIGS. FIG. 4 is a perspective view showing the shoji 15 in a longitudinal section. FIG. 5 is an enlarged longitudinal sectional view showing the lower arm 17 of the shoji 15. FIG. 6 is a cross-sectional view showing the gasket 20 provided on the shoji 15. FIG. 7 is a three-side view showing the gasket 20. 8 and 9 are diagrams for explaining the operation of the gasket 20.
3-7, the double-glazed glass 19 has a pair of indoor and outdoor glass panels 191 and 192, a hollow layer 193 formed between these glass panels 191 and 192, and four rounds between the glass panels 191 and 192. The spacer 194 and the sealing material 195 are interposed. The hollow layer 193 is filled with a gas having low thermal conductivity such as argon gas, and the heat insulating performance of the multilayer glass 19 is enhanced. The multi-layer glass 19 is supported via gaskets 20 on the face member support portions 161 and 171 of the upper and lower halves 16 and 17 and the left and right vertical rods 18 (the surface material support portions of the vertical rod 18 are not shown). Has been.

  The face material support portions 161 and 171 have side walls 162 and 172 facing the inside and outside of the room, and are formed in a concave groove shape. Further, drain holes 174 are provided in the bottom surface 173 of the face material support part 171 in the lower rod 17 at an appropriate interval so that rain water, condensed water, etc. that have entered the face material support parts 161 and 171 can be drained to the outdoor space. It is like that. Then, a setting block 175 is installed on the bottom surface 173 of the face material support portion 171 at two positions on the left and right in the longitudinal direction of the lower eyelid 17, and the multilayer glass 19 is placed on the setting block 175.

  A gasket 20 (20A, 20B, 20C) having a substantially U-shaped cross section formed from a rubber-like elastic body such as EPDM rubber or resin is mounted on the four circumferences of the multilayer glass 19, and the gasket 20 portion is used as a face material support portion. The multi-layer glass 19 is supported so as to be immovable with respect to the brazing materials 16, 17, and 18 by press-fitting into 161, 171. The gasket 20 has an upper annular gasket 20A supported by the upper flange 16, a lower gasket 20B supported by the lower flange 17, and a longitudinal gasket 20C supported by the left and right vertical flanges 18 in a continuous four-round manner. Is formed. In other words, the shoji 15 can be assembled by attaching the overall annular gasket 20 to the four peripheral edges of the multilayer glass 19 and then attaching the brazing members 16, 17 and 18 to the four rounds and assembling them. ing.

  The gasket 20 has a cross-section having a bottom surface portion 21 along the end surface of the multilayer glass 19 and a pair of side surface portions 22 extending from the indoor / outer end portion of the bottom surface portion 21 along the indoor / outdoor surface of the multilayer glass 19. It is integrally formed in a substantially U shape. The pair of side surface portions 22 are provided with a first ridge portion 23, a second ridge portion 24, and a third ridge portion 25 that protrude toward the multilayer glass 19, respectively. The first protrusion 23 is formed at the open end (upper end in the lower gasket 20B) of the side surface 22 away from the bottom surface 21, and extends upward in the height direction of the gasket 20 (upward in the lower gasket 20B in FIG. 5). Are inclined and projecting. The second ridge portion 24 is formed at a position closer to the bottom surface portion 21 than the first ridge portion 23 in the side surface portion 22 and is directed downward in the height direction of the gasket 20 (downward in the lower side gasket 20B in FIG. 5). It is inclined and protrudes. On the bottom surface 21 side of the second protrusion 24, a gap (space) defined by the second protrusion 24, the side surface 22, and the multilayer glass 19 is formed. Two third protrusions 25 are formed between the first protrusion 23 and the second protrusion 24, and protrude toward the surface of the multilayer glass 19.

On the bottom surface portion 21 of the gasket 20, two fourth ridge portions 26 protruding toward the end surface of the multilayer glass 19 are formed. These fourth protrusions 26 are in contact with the end surfaces of the glass panels 191 and 192 inside and outside the multi-layer glass 19 to position the multi-layer glass 19 and end surfaces of the multi-layer glass 19 (in particular, the sealing material 195). ) And the bottom surface portion 21 of the gasket 20 is formed with a gap (space). This space is communicated with the outdoor space via openings 28 and 29 described later and drainage holes 174 of the face material support 171, thereby forming a space that is equal in pressure to the outside air. Intrusion of rainwater or the like into the gasket 20 is suppressed.
Further, two fifth protrusions 27 that are in close contact with the inner surfaces of the side walls 162 and 172 of the face material support portions 161 and 171 are formed on the outer side of the side surface portion 22 of the gasket 20. These fifth protrusions 27 are provided so as to project substantially orthogonally toward the side walls 162 and 172 of the face material support portions 161 and 171.

  As shown in FIGS. 6 and 7, an opening 28 is formed at the base end portion of the bottom surface portion 21 and the side surface portion 22 in the substantially entire length of the lower side gasket 20 </ b> B and the upper and lower ends of the vertical side gasket 20 </ b> C. . Moreover, the opening 30 whose prospective direction dimension is smaller than the opening 28 is formed in the bottom face part 21 of the longitudinal direction both ends of the lower gasket 20B and the longitudinal lower end of the longitudinal gasket 20C. The opening 30 of the lower gasket 20B is for facilitating drainage of rainwater or the like flowing through the vertical gasket 20C as it is, and rainwater or the like from the vertical gasket 20C passes through the lower gasket 20B. It is possible to make it difficult to enter in the longitudinal direction. The opening 30 of the longitudinal gasket 20C is for facilitating drying of the lower end portion in the longitudinal direction of the longitudinal gasket 20C in which rainwater or the like tends to stay. If these openings 30 are formed as large as the openings 28, the assembling and mounting properties of the gasket 20 are deteriorated. Therefore, the openings 30 are not formed on the side surface portions 22 but only on the bottom surface portions 21. It is smaller than the prospective dimension. The setting block 175 can support the lower end surface of the multi-layer glass 19 through the opening 28 of the lower gasket 20B, and rainwater or the like that has entered between the multi-layer glass 19 and the lower gasket 20B promptly passes through the opening 28 or 30. It can be drained. And the movement prevention block which is not shown in figure is provided in the opening 28 position of the longitudinal gasket 20C, and when the shoji 15 is laid down and conveyed, the shift | offset | difference of the multilayer glass 19 can be prevented now. An opening 29 smaller than the opening 28 and the opening 30 is formed in the bottom surface portion 21 in the middle portion of the vertical gasket 20C and the substantially entire length of the upper gasket 20A, and moisture at the position of the sealing material 195 on the end surface of the multilayer glass 19 is formed. Can be prevented.

  In the gasket 20 described above, the shape dimensions of the first ridge portion 23, the second ridge portion 24, and the third ridge portion 25 when not attached to the multilayer glass 19 are set as shown in FIG. ing. That is, the prospective direction interval dimension L1 between the tips of the first ridges 23 facing each other and the prospective direction interval dimension L2 between the tips of the second ridges 24 are respectively from the thickness dimension T1 of the multilayer glass 19. The first protrusion 23 and the second protrusion 24 are in close contact with the indoor and outdoor surfaces of the multilayer glass 19 while being bent. The distance dimension L1 is set smaller than the distance dimension L2 (L1 <L2), that is, the expected protrusion length of the first protrusion 23 is longer than the expected protrusion length of the second protrusion 24. It is set so that the contact strength between the first protrusion 23 and the multilayer glass 19 is greater than the contact strength between the second protrusion 24 and the multilayer glass 19.

  Further, the expected direction distance L2 between the tips of the second ridges 24 is set to be smaller than the expected direction distance L3 between the tips of the third ridges 25 (L2 <L3). The distance L3 between the protrusions 25 is set to be substantially the same as the thickness dimension T1 of the multilayer glass 19. That is, the projected length in the prospective direction of the third ridge portion 25 is set so as to contact the indoor and outdoor surfaces of the multi-layer glass 19 having the same expected thickness dimension as the thickness dimension T1. Such a third ridge portion 25 is formed when the wind pressure acts on the sliding window 1 and the multi-layer glass 19 is pushed indoors (or pulled to the outdoor side by negative pressure). While closely contacting the indoor side surface (or outdoor side surface) of the layer glass 19, the movement of the multilayer glass 19 is restricted, and the first and second ridges 23 and 2 on the outdoor side (or indoor side) are also provided. 24 and the surface of the multilayer glass 19 function so as to maintain a close contact state.

  Furthermore, since the multilayer glass 19 that has received the wind pressure bends into a curved surface as a whole, the edge portion of the multilayer glass 19 at the position of the first protrusion 23 on the outdoor side (or indoor side) The amount of deformation is large, and the surface of the multilayer glass 19 moves (rotates) away from the first protrusion 23, but in the gasket 20 of the present embodiment, the protrusion length of the first protrusion 23 is shown. Is set longer than the second ridge 24 and the third ridge 25, so that the first ridge 23 can follow the deformation of the multi-layer glass 19, and these close states are maintained even in strong winds. Thus, water tightness is ensured.

Further, as shown in FIGS. 8 and 9, the gasket T is formed even when the thickness T2 and T3 of the multi-layer glass 19 is larger or smaller than the expected distance L3 between the tips of the third protrusions 25. The watertightness by 20 and the mounting property of the gasket 20 to the multilayer glass 19 are ensured.
That is, as shown in FIG. 8, when the thickness dimension T2 of the multi-layer glass 19 is larger than the L3, the multi-layer glass 19 is held by the third protrusion 25 being crushed. . At this time, the two third protrusions 25 are formed to have inclined surfaces that are inclined to the side away from each other (see FIG. 6), and thus are easily crushed when pressed. The frictional resistance at the time of mounting to 19 can be made small. Thereby, the mounting property of the gasket 20 to the multilayer glass 19 is ensured.

  On the other hand, as shown in FIG. 9, when the thickness dimension T3 of the multilayer glass 19 is smaller than the L3, the third protrusion 25 is separated from the multilayer glass 19, but from the third protrusion 25. In addition, since the first protrusion 23 and the second protrusion 24, which have a long protrusion length, are in close contact with the surface of the multilayer glass 19, water tightness is ensured. When the wind pressure is applied, the surface of the multi-layer glass 19 moved by a small amount and the third protrusion 25 are in close contact with each other to prevent the multi-layer glass 19 from moving further. The water tightness of the time is also secured.

According to this embodiment, there are the following effects.
(1) That is, the 1st protrusion part 23, the 2nd protrusion part 24, and the 3rd protrusion part 25 are formed in the side part 22 of the gasket 20, At least the 1st protrusion part 23 and the 2nd protrusion part Since 24 closely contacts the indoor and outdoor surfaces of the multilayer glass 19, it is possible to reliably prevent rainwater and the like from entering between the multilayer glass 19 and the gasket 20, and to ensure water stopping.

(2) The distance L1 between the first protrusions 23 is set to be smaller than the distance L2 between the second protrusions 24 (L1 <L2), that is, the protrusion length of the first protrusion 23. Is made longer than the second ridge 24, and the tightness between the first ridge 23 and the multilayer glass 19 is greater than the tightness between the second ridge 24 and the multilayer glass 19. By being set, it is possible to improve the wearability of the gasket 20 by reducing the frictional resistance between the second ridge portion 24 and the multilayer glass 19 while ensuring the water stoppage by the first ridge portion 23. it can.

(3) Further, the distance L3 between the third protrusions 25 is set to be substantially the same as the thickness T1 of the multilayer glass 19, that is, the third protrusion 25 is in contact with the surface of the multilayer glass 19. Therefore, when the gasket 20 is mounted on the multi-layer glass 19, the friction resistance between the third protrusion 25 and the multi-layer glass 19 is reduced to improve the mountability of the gasket 20. In addition, even if the first ridge 23 and the second ridge 24 are deformed by wind pressure acting on the multilayer glass 19, the third ridge 25 closely contacts the multilayer glass 19 and moves. It is possible to prevent the wind pressure from being increased by ensuring the water-stopping property during strong winds.

(4) When the thickness of the multilayer glass 19 varies and the thickness dimension T3 is smaller than the expected distance L3 between the tips of the third protrusions 25, the first protrusions 23 and When the second ridge portion 24 follows, water stoppage can be secured, and when the thickness dimension T2 of the multi-layer glass 19 is larger than the prospective direction interval dimension L3 between the tips of the third ridge portion 25, Since the third ridge portion 25 is crushed (flexed) together with the first ridge portion 23 and the second ridge portion 24, the mounting property of the gasket 20 to the multilayer glass 19 can be maintained well. Therefore, even when the multi-layer glass 19 having a large thickness dimension tolerance is used, it is possible to remarkably exhibit the effect that the deterioration of the wearability can be prevented while securing the water-stopping property.

(5) Further, the fourth protrusion 26 formed on the bottom surface portion 21 of the gasket 20 abuts against the edges of the glass panels 191 and 192 inside and outside the multilayer glass 19, so that the sealing material 195 of the multilayer glass 19. And the bottom surface portion 21 of the gasket 20 are separated from each other, and a gap (space) is formed between them. As a result, even if rainwater or the like enters between the multilayer glass 19 and the gasket 20, the rainwater or the like does not touch the sealing material 195, so that the sealing material 195 is permeated and the multilayer glass 19 is hollow. Intrusion of moisture into the layer 193 can be prevented.

(6) Moreover, the 5th protrusion 27 is formed in the side surface part 22 outer side of the gasket 20, This 5th protrusion 27 closely_contact | adheres to the side wall 162,172 internal surface of the face material support parts 161,171, ie, a gasket. 20 and each brazing material 16, 17, 18 are configured to be in point contact with each other. Therefore, when assembling the shoji to attach the multilayer glass 19 with the gasket 20 attached to each brazing material 16, 17, 18 to the gasket 20, In addition, the friction between the sliding members 16, 17, and 18 can be reduced, and the workability of the assembly operation of the shoji 15 can be improved.

(7) Further, since the opening 28 and the opening 30 are formed in the bottom surface portion 21 of the lower gasket 20B, even if rainwater or the like enters between the multilayer glass 19 and the gasket 20, this rainwater And the like can be prevented from being quickly discharged from the opening 28 and coming into contact with the edge of the multilayer glass 19. Therefore, by keeping the gasket 20 dry, deterioration of the sealing material 195 of the multilayer glass 19 and clouding of the inner surface of the hollow layer 193 can be reliably prevented.

(8) Further, since the gasket 20 is formed in a continuous annular shape along the four peripheral edges of the multi-layer glass 19 by a rubber-like elastic body such as elastic EPDM rubber or resin, Since it can be easily attached by simply attaching it to the double-glazed glass 19, and the attached gasket 20 can hardly be detached, the assemblability of the double-glazed glass 19 and the brazing members 16, 17, 18 can be improved. it can.

In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.
For example, in the above-described embodiment, the sliding window 1 has been described.
