The glass panel 10 is attached to a glass groove 17 formed in the frame 13 via a glass channel 100. Below, we will explain how the glass channel 100 attached to the lower end of the glass panel 10 is attached to the glass groove 17 formed in the lower frame 15. The glass channel 100 attached to the upper end of the glass panel 10 is configured upside down, while the glass channel 100 attached to the widthwise end of the glass panel 10 is configured rotated 90 degrees; explanations will be omitted.

As shown in Figure 3, the bottom frame 15 has a metal frame portion 150 made of metal and a resin frame portion 156 made of resin. The resin frame portion 156 is engaged with the indoor side of the metal frame portion 150. The metal frame portion 150 has a glass groove bottom wall portion 151, an outdoor-side glass groove side wall portion 152, and an indoor-side glass groove side wall portion 153. The bottom frame 15 corresponds to the frame-shaped member in the claims.

The glass groove bottom wall portion 151 is arranged along the indoor-outdoor direction. The glass groove bottom wall portion 151 corresponds to the bottom of the glass groove 17.

The outdoor-side glass channel side wall portion 152 extends upward from the outdoor-side end of the glass channel bottom wall portion 151. A step portion 152b is formed on the lower surface of the wall portion extending indoors at the top of the inner surface 152a of the outdoor-side glass channel side wall portion 152 facing indoors.

The indoor-side glass groove side wall portion 153 extends upward from the indoor-side end of the glass groove bottom wall portion 151. A step portion 153b is formed on the underside of the wall portion extending outdoors at the top of the inner surface 153a of the indoor-side glass groove side wall portion 153 facing outdoors.

The inner surface of the glass groove 17 is formed by the upper surface 151u of the glass groove bottom wall portion 151, the inner surface 152a of the outdoor-side glass groove side wall portion 152, and the inner surface 153a of the indoor-side glass groove side wall portion 153.

The glass channel 100 is attached to the outer peripheral edge of the glass panel 10. The glass channel 100 has a generally U-shaped cross section that opens upward.

The glass channel 100 has a base portion 21 and a pair of side wall portions 26. The glass channel 100 is symmetrical about the center in the groove width direction T1. The following description is based on the state in which the glass panel 10 is attached to the glass channel 100 and mounted on the lower frame 15. The base portion 21 is arranged along the edge surface 10a of the glass panel 10. The base portion 21 abuts against the edge surface 10a of the glass panel 10.

The side wall portion 26 extends upward from the indoor/outdoor end of the base portion 21 along the plate surface 10b of the glass panel 10.

The side wall portion 26 has a first side wall portion 27 and a second side wall portion 28. The first side wall portion 27 extends upward from the indoor/outdoor end of the base portion 21. The lower end of the second side wall portion 28 is connected to the upper end of the first side wall portion 27. The second side wall portion 28 extends upward from the upper end of the first side wall portion 27.

The gray channel 100 is molded using two-color molding. The base portion 21 and first side wall portion 27 are molded from a first resin. The second side wall portion 28, the outer fin portion 272, the first inner fin portion 275, and the second inner fin portion 283 (described later) are molded from a second resin. The hardness of the first resin is higher than that of the second resin. For example, the hardness of the first resin is approximately 100°, and the hardness of the second resin is approximately 70°. More specifically, the hardness of the first resin is 90-100°, and the hardness of the second resin is 60-80°. For example, the first resin is hard polyvinyl chloride, and the second resin is soft polyvinyl chloride.

In the following description, the direction toward the center of the groove width along the indoor/outdoor direction of the glass groove 17 will be referred to as the inside of the groove width direction T1, and the opposite side will be referred to as the outside of the groove width direction T1.

The surface of the first side wall portion 27 facing outward in the groove width direction T1 is referred to as the outer surface 27a. A recess 271 recessed inward in the groove width direction T1 is formed on the outer surface 27a at the middle of the first side wall portion 27 in the vertical direction.

The outer surface 27a of the first side wall 27 is provided with an outer fin portion 272 extending outward in the groove width direction T1. The outer fin portion 272 is connected to the lower part of the recess 271. The outer fin portion 272 is inclined outward with respect to the vertical plane, gradually extending outward in the groove width direction T1 as it extends upward. The tip of the outer fin portion 272 on the outdoor-side first side wall 27 is engaged with the step portion 152b of the outdoor-side glass groove side wall 152 of the bottom frame 15. The tip of the outer fin portion 272 on the indoor-side first side wall 27 is engaged with the step portion 153b of the indoor-side glass groove side wall 153 of the bottom frame 15. When the outer fin portion 272 elastically deforms inward in the groove width direction T1, it can be accommodated within the recess 271.

The position where the tip of the outer fin portion 272 engages with the steps 152b and 153b corresponds to the first position in the claims. The position where the outer fin portion 272 is housed inside the recess 271 corresponds to the second position in the claims.

An upwardly extending upward wall portion 152c is provided above the step portion 152b of the outdoor-side glass channel side wall portion 152. An upwardly extending upward wall portion 153c is provided above the step portion 153b of the indoor-side glass channel side wall portion 153. The upper portion 274 of the first side wall portion 27 extends upward. The upper portion 274 of the outdoor-side first side wall portion 27 abuts the upwardly extending wall portion 152c of the outdoor-side glass channel side wall portion 152. The upper portion 274 of the indoor-side first side wall portion 27 abuts the upwardly extending wall portion 153c of the indoor-side glass channel side wall portion 153.

The surface of the first side wall portion 27 facing inward in the groove width direction T1 is referred to as the inner surface 27b. A first inner fin portion 275 extending inward in the groove width direction T1 is provided on the inner surface 27b of the first side wall portion 27. The base end portion 275a of the first inner fin portion 275 is inclined inward with respect to the vertical plane so as to gradually move inward in the groove width direction T1 as it extends downward. The tip portion 275b on the tip side of the base end portion 275a of the first inner fin portion 275 faces vertically downward and is pressed against the plate surface 10b of the glass panel 10. The tip portion 275b of the first inner fin portion 275 that is pressed against the plate surface 10b of the glass panel 10 is located lower, toward the base end of the side wall portion 26, than the point where the outer fin portion 272 engages with the step portions 152b, 153b.

The surface of the second side wall portion 28 facing outward in the groove width direction T1 is referred to as the outer surface 28a. The outer surface 28a of the second side wall portion 28 is provided with a locking projection 281 that protrudes outward in the groove width direction T1. The outdoor-side second side wall portion 28 is locked to the upper end of the upward wall portion 152c of the lower frame 15. The indoor-side second side wall portion 28 is locked to the upper end of the resin frame portion 156 that is locked to the upper end of the upward wall portion 153c of the lower frame 15.

The surface of the second side wall portion 28 facing inward in the groove width direction T1 is referred to as the inner surface 28b. A seal piece 282 is provided at the upper end of the inner surface 28b of the second side wall portion 28. The seal piece 282 is inclined inward with respect to the vertical plane so that it gradually faces inward in the groove width direction T1 as it extends upward. The seal piece 282 is pressed against the plate surface 10b of the glass panel 10.

A second inner fin portion 283 extending inward in the groove width direction T1 is provided at the lower end of the inner surface 28b of the second side wall portion 28. The second inner fin portion 283 is located higher than the first inner fin portion 275, closer to the tip end in the extension direction of the side wall portion 26. The base end portion 283a of the second inner fin portion 283 is inclined inward with respect to the vertical plane, gradually moving inward in the groove width direction T1 as it extends downward. The tip end portion 283b on the tip side of the base end portion 283a of the second inner fin portion 283 faces vertically downward and is pressed against the plate surface 10b of the glass panel 10.

A protrusion 284 that protrudes inward in the groove width direction T1 is provided on the inner surface 28b of the second side wall portion 28. The protrusion 284 is located slightly above the second inner fin portion 283, closer to the tip end in the extension direction of the side wall portion 26.

The deformation of the outer fin portion 272 when the glass channel 100 is attached to the lower frame 15 will be described. As shown in FIG. 4, with the glass channel 100 attached to the glass panel 10, the outer edge of the glass panel 10 is inserted into the glass groove 17 of the lower frame 15. The outer fin portion 272 provided on the first side wall portion 27 on the indoor side contacts the upward wall portion 153c of the lower frame 15, causing its base end to elastically deform and its tip to point vertically upward and be accommodated inside the recess 271. As shown in FIG. 3, when the tip of the outer fin portion 272 overcomes the upward wall portion 153c, the base end elastically deforms so that the tip of the outer fin portion 272 faces outward in the groove width direction T1. As the outer fin portion 272 extends upward, it gradually tilts outward relative to the vertical plane, gradually pointing outward in the groove width direction T1. The tip of the outer fin portion 272 engages with the step portion 152b of the outdoor-side glass channel side wall portion 152 of the lower frame 15. The outer fin portion 272 provided on the outdoor-side first side wall portion 27 also deforms in the same way as the outer fin portion 272 provided on the indoor-side first side wall portion 27 shown above, so further explanation will be omitted.

In the fitting 1, the hardness of the second resin forming the first inner fin portion 275 and the second inner fin portion 283 of the glass channel 100 is lower than the hardness of the first resin forming the base portion 21 and the first side wall portion 27. As a result, when the outer peripheral edge of the glass panel 10 is inserted into the glass channel 100, the first inner fin portion 275 and the second inner fin portion 283 do not deform and create resistance, making insertion easier.

Because the first inner fin portion 275 of the glass channel 100 is located toward the base end of the first side wall portion 27, when inserting the outer peripheral edge of the glass panel 10 into the glass channel 100, the plate surface 10b of the glass panel 10 abuts the first inner fin portion 275 just before the end face 10a of the glass panel 10 approaches the base portion 21 of the glass channel 100. Frictional resistance is reduced when inserting the outer peripheral edge of the glass panel 10 into the glass channel 100, allowing for smoother insertion than when the first inner fin portion 275 is located toward the tip end of the second side wall portion 28 or near the second inner fin portion 283.

The hardness of the first resin forming the base portion 21 of the glass channel 100 is greater than the hardness of the second resin forming the second side wall portion 28, outer fin portion 272, first inner fin portion 275, and second inner fin portion 283. This makes it easier to insert the glass panel 10 into the glass groove 17 because the base portion 21, which holds the outer edge of the glass panel 10, is less likely to deform.

The hardness of the first resin forming the first side wall portion 27 of the glass channel 100 is greater than the hardness of the second resin forming the second side wall portion 28, outer fin portion 272, first inner fin portion 275, and second inner fin portion 283. This reduces frictional resistance when the first side wall portion 27 comes into contact with the upward wall portions 152c, 153c of the glass channel 17 during insertion into the glass channel 17, allowing for smooth insertion.

When the outer peripheral edge of the glass panel 10 is inserted into the glass groove 17 with the glass channel 100 attached to the outer peripheral edge of the glass panel, the outer fin portion 272 of the glass channel 100 comes into contact with the upward wall portions 152c, 153c of the lower frame 15, elastically deforms so that it faces vertically upward and is accommodated inside the recess 271. This makes it easy to insert the outer fin portion 272 into the glass groove 17 without it interfering with the upward wall portions 152c, 153c of the lower frame 15, etc.

After the glass channel 100 is attached to the glass groove 17 of the lower frame 15, the outer fin portion 272 engages with the step portions 152b and 153b of the glass groove 17. This prevents the glass channel 100, along with the glass panel 10, from coming off the glass groove 17 of the lower frame 15.

The first inner fin portion 275 and the second inner fin portion 283 of the glass channel 100 are pressed against the plate surface 10b of the glass panel 10. As a result, when a force acts on the glass panel 10 in a direction that causes it to come out of the glass channel 100, the first inner fin portion 275 and the second inner fin portion 283 resist the force in the direction that causes it to come out, thereby preventing the glass panel 10 from coming out of the glass channel 100.

When a force acts on the glass panel 10 in a direction that causes it to come out of the glass channel 100, the tip of the second inner fin portion 283 is pulled by the plate surface 10b of the glass panel 10 and attempts to flip in the direction of the removal. At this time, the second inner fin portion 283 comes into contact with the protrusion 284, preventing the flip. This prevents the glass panel 10 from coming out of the glass channel 100.

Second Embodiment
Next, a glass panel edge holding member according to a second embodiment will be described mainly with reference to Fig. 5. In the description of the embodiment and modified examples shown below, the same members as those described above are given the same reference numerals, and their description will be omitted.

As shown in FIG. 5, the side wall portion 26A of the grate channel 100A has a first side wall portion 27A and a second side wall portion 28A. The first side wall portion 27A extends upward from the indoor/outdoor end of the base portion 21. The lower end of the second side wall portion 28A is connected to the upper end of the first side wall portion 27A. The second side wall portion 28A extends upward from the upper end of the first side wall portion 27A.

An outwardly recessed recess 22 is formed on the inner surface of the corner between the base portion 21 and the first side wall portion 27A. The thickness of the first side wall portion 27A is thinner than the thickness of the base portion 21. The first side wall portion 27A is inclined outward with respect to the vertical plane, gradually moving outward in the groove width direction T1 as it extends upward.

The gray channel 100A is molded using two-color molding. The base portion 21, first side wall portion 27A, and the outer protrusion 276 and inner protrusion 277 (described later) are molded from a first resin. The second side wall portion 28A and the second inner fin portion 283 (described later) are molded from a second resin. The hardness of the first resin is higher than the hardness of the second resin. For example, the hardness of the first resin is approximately 100°, and the hardness of the second resin is approximately 70°.

An outer protrusion 276 protruding upward is provided on the outer surface 27a of the first side wall portion 27A at the vertical middle. When an upward force is applied to the glass panel 10, the outer protrusion 276 comes into contact with and engages with the steps 152b, 153b of the glass groove 17.

An inner protrusion 277 that protrudes inward and downward in the groove width direction T1 is provided on the inner surface 27b of the first side wall portion 27A. The inner protrusion 277 is located lower than the outer protrusion 276, closer to the base end of the side wall portion 26. The inner protrusion 277 abuts against the plate surface 10b of the glass panel 10.

When the glass channel 100A is attached to the outer peripheral edge of the glass panel 10, the distance A1 between the pair of outer protrusions 276 is longer than the distance A2 between the upward wall portions 152c, 153c of the glass groove 17. When the outer peripheral edge of the glass panel 10 is inserted into the glass groove 17, the recessed portions 22 formed at the corners between the base portion 21 and the first side wall portions 27A make the pair of first side wall portions 27A more likely to bend inward in the groove width direction T1, narrowing the width. Pressed by the pair of first side wall portions 27A, the upward wall portions 152c, 153c expand outward in the groove width direction T1, and the outer surface 27a of the first side wall portion 27A slides along the inner surfaces of the upward wall portions 152c, 153c. When the outer protrusions 276 overcome the upward wall portions 152c, 153c, the pair of first side wall portions 27A expand outward in the groove width direction T1 and return to their original state.

In the fitting 1, the hardness of the second resin forming the second inner fin portion 283 of the glass channel 100A is lower than the hardness of the first resin forming the base portion 21 and the first side wall portion 27A. As a result, when the outer edge of the glass panel 10 is inserted into the glass channel 100A, the second inner fin portion 283 does not deform and provide resistance, making insertion easier.

A highly rigid inner protrusion 277 is provided on the first side wall 27A, which is the base end portion of the side wall 26A of the glass channel 100A. This makes it easier to insert the outer peripheral edge of the glass panel 10 into the glass channel 100A, as the inner protrusion 277 guides the plate surface 10b of the glass panel 10.

The hardness of the first resin forming the base portion 21 of the glass channel 100A is greater than the hardness of the second resin forming the second side wall portion 28A and the second inner fin portion 283. This makes it easier to insert the glass panel 10 into the glass groove 17 because the base portion 21, which holds the outer edge of the glass panel 10, is less likely to deform.

The hardness of the first resin forming the first side wall portion 27A of the glass channel 100A is greater than the hardness of the second resin forming the second side wall portion 28A and the second inner fin portion 283. This reduces frictional resistance when the first side wall portion 27A comes into contact with the upward wall portions 152c, 153c of the glass channel 17 during insertion into the glass channel 17, allowing for smooth insertion.

The high-hardness inner protrusions 277 of the glass channel 100A increase the rigidity of the first side wall portion 27A. As a result, the first side wall portion 27A, which holds the outer edge of the glass panel 10, is less likely to deform when inserted into the glass groove 17, making insertion easier.

When an upward force is applied to the glass panel 10, the outer protrusion 276 of the glass channel 100A comes into contact with and engages the steps 152b, 153b of the glass groove 17. As a result, when an upward force is applied to the glass panel 10 in the direction of removing it from the glass channel 100A, the outer protrusion 276 comes into contact with and engages the steps 152b, 153b of the glass groove 17, preventing the glass panel 10 from moving upward any further, thereby preventing the glass channel 100A and the glass panel 10 from coming out of the glass groove 17 of the lower frame 15.

The inner protrusion 277 of the glass channel 100A is made of a first resin with high hardness. This ensures that the glass panel 10 is securely held in place by contacting the plate surface 10b of the glass panel 10, preventing the glass panel 10 from slipping out of the glass channel 100A.

An outwardly recessed recess 22 is formed on the inner surface of the corner between the base portion 21 and the first side wall portion 27A of the glass channel 100A. The thickness of the first side wall portion 27A is thinner than the thickness of the base portion 21. As a result, after the glass panel 10 is inserted into the glass groove 17 of the lower frame 15, the first side wall portion 27A of the glass channel 100A expands outward in the groove width direction T1, ensuring that the outer protrusion 276 can be securely engaged with the steps 152b, 153b of the glass groove 17.

(Variation 1)
Next, the edge holding member for a glass panel according to the first modification will be described mainly with reference to FIG.

As shown in FIG. 6, an inner protrusion 278 that protrudes inward in the groove width direction T1 is provided on the inner surface 27b of the first side wall portion 27B of the glass channel 100B. The inner protrusion 278 is located lower than the outer protrusion 276, closer to the base end of the side wall portion 26. The inner protrusion 278 abuts against the plate surface 10b of the glass panel 10.

When the glass channel 100B is attached to the outer peripheral edge of the glass panel 10, the distance A1 between the pair of outer protrusions 276 is longer than the distance A2 between the upward wall portions 152c, 153c of the glass groove 17. When the outer peripheral edge of the glass panel 10 is inserted into the glass groove 17, the recessed portions 22 formed at the corners between the base portion 21 and the first side wall portions 27B make it easier for the pair of first side wall portions 27B to bend inward in the groove width direction T1, narrowing the width. When the outer surfaces 27a of the first side wall portions 27B slide over the inner surfaces of the upward wall portions 152c, 153c and the outer protrusions 276 climb over the upward wall portions 152c, 153c, the pair of first side wall portions 27B expand outward in the groove width direction T1 and return to their original state.

In the fitting 1, the hardness of the second resin forming the second inner fin portion 283 of the glass channel 100B is lower than the hardness of the first resin forming the base portion 21 and the first side wall portion 27B. As a result, when the outer edge of the glass panel 10 is inserted into the glass channel 100B, the second inner fin portion 283 does not deform and provide resistance, making insertion easier.

A highly rigid inner protrusion 278 is provided on the first side wall portion 27B, which is the base end portion of the side wall portion 26A of the glass channel 100B. This makes it easier to insert the outer peripheral edge of the glass panel 10 into the glass channel 100B, as the inner protrusion 278 guides the plate surface 10b of the glass panel 10.

The hardness of the first resin forming the base portion 21 of the glass channel 100B is greater than the hardness of the second resin forming the second side wall portion 28A and the second inner fin portion 283. This makes it easier to insert the glass panel 10 into the glass groove 17 because the base portion 21, which holds the outer edge of the glass panel 10, is less likely to deform.

The hardness of the first resin forming the first side wall portion 27B of the glass channel 100B is greater than the hardness of the second resin forming the second side wall portion 28A and the second inner fin portion 283. This reduces frictional resistance when the first side wall portion 27A comes into contact with the upward wall portions 152c, 153c of the glass channel 17 during insertion into the glass channel 17, allowing for smooth insertion.

The high hardness of the inner protrusions 278 of the glass channel 100B increases the rigidity of the first side wall portion 27B. This makes it easier to insert the glass panel 10 into the glass groove 17 because the first side wall portion 27B, which holds the outer edge of the glass panel 10, is less likely to deform.

The inner protrusions 278 of the glass channel 100B are made of a first resin with high hardness. This ensures that the glass panel 10 is securely held in place by contacting the plate surface 10b of the glass panel 10, preventing the glass panel 10 from slipping out of the glass channel 100B.

(Variation 2)
Next, a glass panel edge holding member according to Modification 2 will be described mainly with reference to FIG.

As shown in FIG. 7, the side wall portion 26C of the grate channel 100C has a first side wall portion 27C and a second side wall portion 28C. The first side wall portion 27C is provided with an outer protrusion 276. The second side wall portion 28C is provided with a locking protrusion 281, a seal piece 282, a second inner fin portion 283, a protrusion 284, and a third inner fin portion 285.

The third inner fin portion 285 is provided at the lower end of the inner surface 28b of the second side wall portion 28. The third inner fin portion 285 is located below the second inner fin portion 283. The third inner fin portion 285 is formed from a second resin with low hardness. The base end portion 285a of the third inner fin portion 285 is inclined inward with respect to the vertical plane, gradually moving inward in the groove width direction T1 as it extends downward. The tip end portion 285b on the tip side of the base end portion 253a of the third inner fin portion 285 faces vertically downward and is pressed against the plate surface 10b of the glass panel 10.

When the glass channel 100C is attached to the outer peripheral edge of the glass panel 10, the distance A1 between the pair of outer protrusions 276 is longer than the distance A2 between the upward wall portions 152c, 153c of the glass groove 17. When the outer peripheral edge of the glass panel 10 is inserted into the glass groove 17, the recessed portions 22 formed at the corners between the base portion 21 and the first side wall portions 27C make it easy for the pair of first side wall portions 27C to bend inward in the groove width direction T1, narrowing them. When the outer surfaces 27a of the first side wall portions 27c slide over the inner surfaces of the upward wall portions 152c, 153c and the outer protrusions 276 climb over the upward wall portions 152c, 153c, the pair of first side wall portions 27C expand outward in the groove width direction T1 and return to their original state.

In the fitting 1, the hardness of the second resin forming the second inner fin portion 283 and the third inner fin portion 285 of the glass channel 100C is lower than the hardness of the first resin forming the base portion 21 and the first side wall portion 27C. As a result, when the outer peripheral edge of the glass panel 10 is inserted into the glass channel 100C, the second inner fin portion 283 and the third inner fin portion 285 do not deform and create resistance, making insertion easier.

The hardness of the first resin forming the base portion 21 of the glass channel 100C is greater than the hardness of the second resin forming the second side wall portion 28C, the second inner fin portion 283, and the third inner fin portion 285. This makes it easier to insert the glass panel 10 into the glass groove 17 because the base portion 21, which holds the outer edge of the glass panel 10, is less likely to deform.

The hardness of the first resin forming the first side wall portion 27C of the glass channel 100C is higher than the hardness of the second resin forming the second side wall portion 28C, second inner fin portion 283, and third inner fin portion 285. This reduces frictional resistance when the first side wall portion 27C comes into contact with the upward wall portions 152c, 153c of the glass channel 17 during insertion into the glass channel 17, allowing for smooth insertion.

The first inner fin portion 275 and the third inner fin portion 285 of the glass channel 100C are pressed against the plate surface 10b of the glass panel 10. As a result, when a force acts on the glass panel 10 in a direction that causes it to come out of the glass channel 100C, the first inner fin portion 275 and the third inner fin portion 285 resist the force in the direction that causes it to come out, thereby preventing the glass panel 10 from coming out of the glass channel 100C.
