<First embodiment>
A first embodiment will be described with reference to FIGS. 1 and 2. FIG. FIG. 1 is a vertical cross-sectional view of the main part showing a form in which the windowpane 10 with a glazing channel according to the first embodiment is attached to a window frame 80, and FIG. 5 is a longitudinal section through the glazing channels 50, 50; FIG. In this specification, the cross section of the lower edge of the upper, lower, left, and right edges of the windowpane 10 with glazing channel will be described. Moreover, in FIG. 1, "outdoor" and "indoor" are illustrated.

In the first embodiment, a windowpane 10 with glazing channels is shown in which the above-described separate glazing channels 50, 50 are attached to a windowpane composed of two layers of double glazing 20. FIG. It should be noted that the glazing channel 50 of this example is not limited to the double glazing 20, but can be suitably fitted with a single pane of glass, or other forms of window glass such as wire glass having fire retardant properties. Moreover, the double glazing 20 is not limited to two layers, and may be three or more layers.

The windowpane 10 with glazing channels according to the first embodiment has a double glazing 20 and glazing channels 50, 50, as shown in FIG. The glazing channels 50 , 50 are mounted on side edges 22 a , 24 a corresponding to peripheral edges of the first glass plate 22 and the second glass plate 24 forming the double glazing 20 . The window glass 10 with the glazing channel is attached to, for example, a groove 82 formed in the window frame 80 via a setting block (not shown).

The double glazing 20 includes a first glass plate 22 and a second glass plate 24, and spacers 26 that separate the first glass plate 22 and the second glass plate 24, as shown in FIG. A hollow layer 28 is defined by the first glass plate 22 and the second glass plate 24 and the spacer 26 . Since the spacers 26 are arranged along the side edges of the inner main surfaces of the first glass plate 22 and the second glass plate 24, the spacing between the first glass plate 22 and the second glass plate 24 is kept constant by the spacers 26. be.

The first glass plate 22 and the second glass plate 24 are plates of inorganic glass such as soda lime glass, aluminosilicate glass, aluminoborosilicate glass, or alkali-free glass.

Also, the first glass plate 22 and the second glass plate 24 may be glass plates that have been subjected to strengthening treatment such as physical strengthening treatment or chemical strengthening treatment. Also, the first glass plate 22 and the second glass plate 24 may be known laminated glass in which a plurality of glass plates are bonded together via an intermediate film.

Further, the first glass plate 22 and the second glass plate 24 may be glass plates having functional films formed on their main surfaces to improve their functions. Examples of functional films include low radiation films (Low-E films), antifogging films, antifouling films, and water-repellent films. Furthermore, the first glass plate 22 and the second glass plate 24 are preferably glass plates each having a thickness of, for example, 1 mm or more and 24 mm or less.

The inner main surface of the first glass plate 22 and the surface of the spacer 26 facing the inner main surface are bonded by a primary seal 30 . In addition, the inner main surface of the second glass plate 24 and the surface of the spacer 26 facing the inner main surface are bonded by the primary seal 30 . In addition, the lower (opposite to hollow layer 28) surface of spacer 26 and the inner major surfaces of first and second glass plates 22 and 24 define a concave groove in which the secondary seal is formed. 32 is filled. The secondary seal 32 is in contact with the primary seals 30, 30, and the primary seals 30, 30 and the secondary seal 32 isolate the hollow layer 28 from the atmosphere.

The spacer 26 is hollow and has a cavity. A plurality of vent holes 34 are provided at predetermined intervals along the longitudinal direction of the spacer 26 (the direction perpendicular to the plane of the drawing) on the upper side (the hollow layer 28 side) of the spacer 26 . A vent hole 34 is formed through the hollow portion of the spacer 26 . Thereby, the hollow portion of the spacer 26 and the hollow layer 28 are communicated with each other. Further, since the hollow portion of the spacer 26 is filled with a desiccant 36 such as granular zeolite, the gas in the hollow layer 28 is dried by the desiccant 36 through the ventilation holes 34 .

The spacers 26 may be metal spacers whose main material is aluminum, or may be resin spacers. In the case of a resin spacer, its surface may be covered with an aluminum sheet. When resin spacers are used, the primary seals 30, 30 and the secondary seal 32 may not be used.

The primary seal 30 is preferably made of butyl rubber or polyisobutylene, which is not usually cross-linked, and contains a filler such as carbon black for the purpose of coloring and reinforcement. Since the primary seal 30 does not harden and has only adhesiveness, the adhesion between the spacer 26 and the first glass plate 22 and the second glass plate 24 in the so-called multi-layer glass 20 is ensured by the secondary seal 32. be done.

As the secondary seal 32, for example, polysulfide (manufactured by Yokohama Rubber Co., Ltd.: trade name: Hamatite SM9000), silicone (manufactured by Dow Corning Toray Co., Ltd.: trade name: S
E936), urethane (manufactured by Sanyu Rec Co., Ltd.: product name: SANYU IGS205) or other curable elastomer as a base, which is modified appropriately to exhibit adhesion between the first glass plate 22 and the second glass plate 24. etc. is suitable.

The glazing channels 50, 50 shown in FIG. 2 will now be described with reference to FIG. Since these two glazing channels 50, 50 have the same configuration, they are assigned the same reference numerals for explanation.

As shown in FIG. 2, the glazing channel 50 includes a body portion 52 and a seal portion 54 . The body portion 52 has a bottom portion 52A, a corner portion 52B in contact with the bottom portion 52A, and a side wall portion 52C erected from the corner portion 52B, and has an L-shaped vertical cross-sectional shape. Further, the bottom surface portion 52A and the side wall portion 52C are in a substantially orthogonal positional relationship. Further, the corner portion 52B is located between the bottom portion 52A and the side wall portion 52C and has a function of protecting the edge portion of the double glazing 20. As shown in FIG.

Here, the body portion 52 (bottom portion 52A, corner portion 52B, and side wall portion 52C) has a hardness of 80 degrees or more and 100 degrees or less measured with a type A durometer in accordance with JIS K6253-3 (2012). Constructed from hard materials. This hard member is preferably made of any material selected from the group consisting of polyvinyl chloride, ABS resin, AES resin, chloroprene rubber, ethylene-propylene-diene rubber, silicone rubber, and thermoplastic elastomer. . The hardness is preferably 90 degrees or more and 99 degrees or less, more preferably 95 degrees or more and 99 degrees or less, and even more preferably 96 degrees or more and 99 degrees or less. By configuring the body portion 52 with a hard member (also referred to as a semi-rigid member) having such hardness, the rigidity (hardness) required for the glazing channel 50 and the stability of attachment to the window frame 80 can be achieved. A body portion 52 having both the required flexibility is constructed. In the following description, the term “hardness” means “hardness measured with a type A durometer in accordance with JIS K6253-3 (2012)”.

The sealing portion 54 extends obliquely upward from the upper portion of the side wall portion 52</b>C toward the main surface 20</b>A of the multi-layer glass (window glass) 20 . When the glazing channel 50 is attached to the double glazing 20, the sealing portion 54 is pressed against the main surface 20A of the double glazing 20 as shown in FIG. be done. Also, at this time, the seal portion 54 and the upper portion of the side wall portion 52C (the portion above the adhesive 60 described later) are elastically deformed outward from the main surface 20A of the double glazing 20 . As a result, when the window glass 10 with the glazing channel is attached to the window frame 80, the seal portion 54 and the upper portion of the side wall portion 52C are in close contact with the open end portion 80A of the window frame 80 and its vicinity. As a result, the window glass 10 with glazing channels is stably held on the window frame 80 .

Further, the seal portion 54 has a projecting portion 55 extending obliquely downward from the upper portion of the side wall portion 52C toward the side opposite to the main surface 20A of the multi-layer glass (window glass) 20 . When the window glass 10 with the glazing channel is attached to the window frame 80 of FIG. is elastically deformed toward the main surface 20A side of the multi-layer glass 20 as indicated by the two-dot chain line. By providing the sealing portion 54 with such a protruding portion 55 , the adhesion and watertightness of the glazing channel 50 to the double glazing 20 are improved in cooperation with the window frame 80 .

The seal portion 54 is made of a soft member having a hardness of 50 degrees or more and less than 80 degrees. Naturally, a soft resin that is softer than the body portion 52 is preferable as the soft member. Also, in this case, a flame-retardant soft resin is preferable.

The main body portion 52 and the seal portion 54 are preferably integrally formed by extrusion molding. In this case, a resin material that can be extruded is used as the material of the body portion 52 and the seal portion 54 . As the resin material, various materials such as thermoplastic resin material, thermosetting resin material, and moisture-curable resin material can be exemplified. Among them, thermoplastic resin materials are preferable in view of the fact that they are immediately solidified only by standing to cool after extrusion, and among these, flame-retardant polyvinyl chloride resin materials that satisfy the hardness described above are particularly preferable.

Moreover, the glazing channel 50 preferably has a support portion 56 attached to the surface of the seal portion 54 (the lower surface of the seal portion 54 in FIGS. 1 and 2). The support portion 56 extends obliquely upward from the upper end of the side wall portion 52</b>C extending vertically toward the main surface 20</b>A of the double glass 20 . The support portion 56 is made of a hard member having a hardness of 80 degrees or more and 100 degrees or less, and has a function of reinforcing the strength of the seal portion 54 . Since the support portion 56 is formed integrally with the side wall portion 54C, the support portion 56 can be easily arranged in the seal portion 54. As shown in FIG. Further, since the support portion 56 is arranged on the lower surface of the seal portion 54, the interface between the seal portion 54 and the support portion 56 is not exposed to the outside. 10 can be configured. In addition, since the support portion 56 does not protrude from the seal portion 54, the main surface 20A of the multi-layer glass 20 may be subjected to pressure such as wind pressure, or an object such as a packing material may hit the main surface 20A. Even if 20A receives force, the support portion 56, which is a hard member, does not abut against the double glazing 20, so that the double glazing 20 is less likely to break and can be held stably.

Further, the glazing channel 50 preferably further includes a tongue-like portion 58 in addition to the sealing portion 54 described above. The tongue portion 58 extends obliquely downward from the upper portion of the side wall portion 52C toward the main surface 20A of the double glazing 20 . When the glazing channel 50 is attached to the double glazing 20, the tongue 58 is pressed against the main surface 20A of the double glazing 20 as shown in FIG. be in close contact. Similar to the sealing portion 54, the tongue-shaped portion 58 is also made of a soft member (for example, a soft polyvinyl chloride resin material) having a hardness of 50 degrees or more and less than 80 degrees, and is integrally formed by extrusion molding. is preferred.

When the main body portion 52, the seal portion 54, and the tongue portion 58 are made of a resin material such as polyvinyl chloride resin, the hardness can be adjusted by blending a plasticizer. Hardness generally decreases with increasing plasticizer. Examples of plasticizers include phthalate esters (DOP, DINP, DIDP, DUP), adipate esters, polyester plasticizers, epoxy plasticizers, trimellitic acid plasticizers, and phosphoric acid plasticizers. By blending 5 or more and 45 or less of the plasticizer when the amount of the resin material is 100, the hardness can be made 100 degrees or less. A hard member with a hardness of 80 degrees or more and 100 degrees or less is preferably mixed with a plasticizer of 5 or more and less than 25 degrees, and a soft member with a hardness of 50 degrees or more and less than 80 degrees is mixed with a plasticizer of 25 or more and 45 degrees or less. Blending is preferred. Further, the hardness of the body portion 52, the seal portion 54, and the tongue portion 58 can be adjusted by changing the molecular structure of the resin material. For example, hardness increases as the molecular weight of the constituent material increases. When the resin material is a rubber-based material, the hardness can be adjusted by adding mineral oil or the like.

In the glazing channel 50 constructed as described above, the side wall portion 52C is adhered to the main surface 20A of the double glazing 20 with an adhesive 60, as shown in FIG. Thus, the window glass 10 with the glazing channel of the first embodiment is constructed.

Here, as the adhesive 60, a double-sided adhesive tape is used as an example. In this case, the inner side surface 52D of the side wall portion 52C to which the double-sided adhesive tape is attached preferably has a flat portion of at least 3 mm or more in the vertical direction, for example. As a result, the adhesive force between the glazing channel 50 and the main surface 20A of the multi-layer glass 20 is enhanced. Note that the adhesive 60 is not limited to the double-sided adhesive tape described above, and other adhesives such as an epoxy-based adhesive or a hot-melt adhesive may be used. However, if the double-sided adhesive tape is used, the curing time (curing time) of the adhesive can be saved, so that the windowpane 10 with the glazing channel can be assembled in a short time.

Further, the glazing channel 50 has a bottom end portion 62 at the other end of the bottom portion 52A opposite to the one end in contact with the corner portion 52B. The bottom end portion 62 is made of a soft member having a hardness of 50 degrees or more and less than 80 degrees. The bottom end portion 62 will be described later.

On the other hand, the window frame 80, as shown in FIG. It has a surface shape. A pair of claw portions 84 are formed in opposing opening end portions 80</b>A of the window frame 80 and function as members for determining the opening width of the window frame 80 . That is, the inner surface of the claw portion 84 serves as a reference for measuring the distance from the window frame 80 .

Next, the operation of the windowpane 10 with glazing channels of the first embodiment will be described.

As shown in FIG. 1, the windowpane 10 with glazing channels of the first embodiment has glazing channels 50, 50 separately attached to the side edges 22a, 24a of the first glass plate 22 and the second glass plate 24. The double glazing 20 is held in the glazing channel 50 by seals 54 , 54 . In this state, for example, when one of the main surfaces (for example, the main surface on the outdoor side) 20A of the double glazing 20 receives pressure such as wind pressure, the double glazing 20 moves in the direction of the pressure (inside the room) ( Therefore, the right sealing portion 54 located in the direction of pressure is pressed. At this time, since the seal portion 54 is made of a soft member, it deforms. On the other hand, the left seal portion 54 and the double glazing 20 located on the opposite side to the direction of the pressure try to separate from each other, and in this case, there is a problem that the holding force of the double glazing 20 by the left seal portion 54 weakens. .

Therefore, in order to solve the above problem, according to the first embodiment, the hard side wall portions 52C of the glazing channel 50 are adhered to both main surfaces 20A of the multi-layer glass 20 with an adhesive (double-sided adhesive tape) 60. is adopted. As a result, when the double glazing 20 receives pressure, the left sealing portion 54 and the double glazing 20 located on the opposite side to the direction of pressure will not separate from each other, and the left sealing portion 54 will prevent the double glazing 20 from separating. The holding force of the multi-layer glass 20 is kept constant. Thereby, according to the windowpane 10 with the glazing channel of the first embodiment, the multi-layered glass (windowpane) 20 can be stably held.

As another aspect, a member other than the side wall portion 52C, for example, a tongue portion 58 may be adhered to the main surface 20A of the double glazing 20 with an adhesive, but the tongue portion 58 is a soft member. Therefore, the above effect cannot be sufficiently obtained. On the other hand, in the first embodiment, since the hard side wall portion 52C is adhered to the main surface 20A of the double glazing 20 by the adhesive 60, the holding force of the double glazing 20 by the sealing portion 54 is constant, The multi-layer glass 20 can be stably held.

Several other embodiments of glazing channel glazings are now described.

<Second embodiment>
FIG. 3 is a vertical cross-sectional view showing the main configuration of the windowpane 100 with glazing channels according to the second embodiment. Also, FIG. 4 is a longitudinal sectional view of the glazing channel 110 applied to the second embodiment. In addition, the same code|symbol is attached|subjected about the component which is common in 1st Embodiment.

Here, the difference between the first embodiment and the second embodiment is that in the windowpane 10 with glazing channels of the first embodiment, separate glazing channels 50, 50 having the same shape as the double glazing 20 are provided. On the other hand, in the windowpane 100 with glazing channels of the second embodiment, an integrated glazing channel 110 is attached to one glass plate 102 constituting the windowpane. Since other configurations are the same, the description is omitted.

As shown in FIG. 4, the body portion 112 of the glazing channel 110 includes a bottom portion 52A, a pair of corner portions 52B and 52B contacting both ends of the bottom portion 52A, and a pair of corner portions 52B and 52B. It has a pair of side wall portions 52C, 52C that are inclined, and has a U-shaped vertical cross-sectional shape. Also, the bottom surface portion 52A has a first bottom surface portion 52Aa and a second bottom surface portion 52Ab, and the first bottom surface portion 52Aa and the second bottom surface portion 52Ab are connected via a connecting portion 114 . The connecting portion 114 is made of a soft member (for example, a soft polyvinyl chloride resin material) having a hardness of 50 degrees or more and less than 80 degrees, and is formed integrally with the main body portion 112 and the sealing portion 54 by extrusion molding. .

In the second embodiment, as in the first embodiment, the glazing channel 110 has rigid side walls 52C, 52C adhered to both main surfaces 102A, 102A of the glass plate 102 with adhesives 60, 60. As shown in FIG. As a result, when the glass plate 102 receives pressure, the sealing portion 54 and the glass plate 102 located on the opposite side of the pressure direction do not move away from each other. remains constant. Thereby, according to the windowpane 100 with the glazing channel of the second embodiment, the glass plate (windowpane) 102 can be stably held. Also, if there is an error in the thickness of the glass plate 102, the sealing portion 54 and the upper portion of the side wall portion 52C (the portion above the adhesive 60) are outside the main surfaces 102A of the glass plate 102, 102A. The error can be absorbed by elastic deformation toward the direction.

Here, as shown in FIGS. 3 and 4, the connecting portion 114 preferably has an indentation (groove) 115 . When this recessed portion 115 is formed on both the lower surface (the side opposite to the glass plate 102) and the upper surface (the side facing the glass plate 102) of the body portion 112, the recessed portion 115 shown in FIG. The U-shaped glazing channel 110 of FIG. 4 can be easily changed to the flat plate-shaped form of FIG. Also, the form of the glazing channel 110 can be easily changed from the form shown in FIG. 5 to the form shown in FIG. Note that the adhesive (double-sided adhesive tape) 60 is preferably attached to the side wall portion 52C in the form shown in FIG. At this time, a primer may be used.

The form shown in FIG. 5 is, for example, a suitable form for winding the glazing channel 110 on a roll (not shown). When the glazing channel 110 in the form of FIG. 5 is wound into a roll, the flexibility of the connecting portion 114 prevents the body portion 112 from plastically deforming, and the connecting portion 114 can be repeatedly opened and closed without being connected. The portion 114 is not arbitrarily divided.

The invagination portion 115 may be formed only on the upper surface of the main body portion 112 (the inner surface facing the peripheral portion of the glass plate 102 in the longitudinal section of the connecting portion 114) or only on the lower surface (the outer surface opposite to the inner surface). However, from the viewpoint of easily changing the form of the glazing channel 110 between the form shown in FIG. 4 and the form shown in FIG.

In addition, the connecting portion 114 can be divided along the boundary of the invagination portion 115 having a reduced thickness. In other words, when the connection portion 114 is broken at the invagination portion 115, the bottom end portion 62 shown in FIGS. . That is, the separate glazing channel 50 shown in FIGS. 1 and 2 has the same shape as the glazing channel 110 shown in FIGS. In other words, by providing the main body portion 112 with the flexible connecting portion 114, the shape of the integrated glazing channel 110 can be easily changed to the separate glazing channel 50. FIG.

<Third Embodiment>
FIG. 6 is a vertical cross-sectional view showing the main configuration of a windowpane 120 with a glazing channel according to the third embodiment. Also, FIG. 7 is a longitudinal sectional view of the glazing channel 130 applied to the third embodiment. In addition, the same code|symbol is attached|subjected about the component which is common in 1st thru|or 2nd embodiment.

Here, the difference between the first embodiment and the third embodiment is that in the windowpane 10 with glazing channels of the first embodiment, separate glazing channels 50, 50 having the same shape as the double glazing 20 are provided.
