[0017] The indoor-side glass groove side wall portion 153 extends upward from the indoor-side end of the glass groove bottom wall portion 151. At the upper part of the inner surface 153a of the indoor-side glass groove side wall portion 153 facing the outdoor side, a step portion 153b is formed on the underside of the wall portion extending to the outdoor side.

[0018] 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 form the inner surface of the glass groove 17.

[0019] The glass channel 100 is attached to the outer peripheral edge of the glass panel 10. The glass channel 100 has a substantially U-shaped cross section that opens upward.

[0020] The glass channel 100 has a base portion 21 and a pair of side wall portions 26. The glass channel 100 has a shape that is symmetrical about the center in the groove width direction T1. The following description will be 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.

[0021] The side wall portion 26 extends upward along the plate surface 10b of the glass panel 10 from the end of the base portion 21 facing the indoor / outdoor direction.

[0022] 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.

[0023] The gray channel 100 is molded by two-color molding. The base portion 21 and the 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, which will be 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 about 100°, and the hardness of the second resin is about 70°.

[0024] In the following description, the direction toward the center of the groove width along the indoor / outdoor direction of the glass groove 17 is referred to as the inside of the groove width direction T1, and the opposite side is referred to as the outside of the groove width direction T1.

[0025] The surface of the first side wall portion 27 facing outward in the groove width direction T1 is referred to as an outer surface 27a. A recess 271 recessed inward in the groove width direction T1 is formed on the outer surface 27a at the middle in the vertical direction of the first side wall portion 27.

[0026] An outer fin portion 272 extending outward in the groove width direction T1 is provided on the outer surface 27a of the first side wall portion 27. The outer fin portion 272 is connected to the lower portion of the recess 271. The outer fin portion 272 is inclined outward with respect to the vertical plane so as to gradually extend outward in the groove width direction T1 as it extends upward. The tip of the outer fin portion 272 provided on the outdoor-side first side wall portion 27 is engaged with the step portion 152b of the outdoor-side glass groove side wall portion 152 of the bottom frame 15. The tip of the outer fin portion 272 provided on the indoor-side first side wall portion 27 is engaged with the step portion 153b of the indoor-side glass groove side wall portion 153 of the bottom frame 15. The outer fin portion 272 is capable of being accommodated inside the recess 271 when it elastically deforms inward in the groove width direction T1.

[0027] The position where the tip of the outer fin portion 272 is engaged with the steps 152b, 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.

[0028] An upwardly extending upwardly facing wall portion 152c is provided above the step portion 152b of the outdoor-side glass channel side wall portion 152. An upwardly extending wall portion 153c is provided above the step portion 153b of the indoor-side glass channel side wall portion 153. An 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 against the upwardly facing 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 against the upwardly facing wall portion 153c of the indoor-side glass channel side wall portion 153.

[0029] 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. A base end portion 275a of the first inner fin portion 275 is inclined inward with respect to the vertical plane so as to gradually face inward in the groove width direction T1 as it extends downward. A tip end 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 end 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, closer to the base end of the side wall portion 26, than the locations where the outer fin portion 272 engages with the step portions 152b, 153b.

[0030] 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 protrusion 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 bottom 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 bottom frame 15.

[0031] 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 as to gradually move 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.

[0032] 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. A base end portion 283a of the second inner fin portion 283 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. A 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.

[0033] 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 and closer to the tip end in the extension direction of the side wall portion 26.

[0034] The deformation of the outer fin portion 272 when the glass channel 100 is attached to the sill 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 sill 15. The outer fin portion 272 provided on the first side wall 27 on the indoor side comes into contact with the upward wall portion 153c of the sill 15, causing the base end to elastically deform and the tip to be displaced so as 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 is elastically deformed 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 inclines outward with respect to the vertical plane so as to point 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 groove 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 manner as the outer fin portion 272 provided on the indoor-side first side wall portion 27 shown above, and therefore a description thereof will be omitted.

[0035] In the fitting 1, 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 bottom frame 15, elastically deforms so as to face 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 bottom frame 15, etc.

[0036] After the glass channel 100 is attached to the glass groove 17 of the lower frame 15, the outer fin portion 272 is engaged with the step portions 152b, 153b of the glass groove 17. This prevents the glass channel 100 from coming off the glass groove 17 of the lower frame 15 together with the glass panel 10.

[0037] The hardness of the first resin forming the base portion 21 of the glass channel 100 is higher than the hardness of the second resin forming the second side wall portion 28, the outer fin portion 272, the first inner fin portion 275, and the second inner fin portion 283. As a result, the base portion 21 that holds the outer peripheral edge of the glass panel 10 is less likely to deform when inserted into the glass groove 17, making insertion easier.

[0038] The hardness of the first resin forming the first side wall portion 27 of the glass channel 100 is higher than the hardness of the second resin forming the second side wall portion 28, the outer fin portion 272, the first inner fin portion 275, and the second inner fin portion 283. This reduces the 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.

[0039] 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 inserting the outer peripheral end portion of the glass panel 10 into the glass channel 100, the first inner fin portion 275 and the second inner fin portion 283 are easily deformed, making the insertion easier.

[0040] A first inner fin portion 275 provided on the inner surface 27b of the first side wall portion 27 of the glass channel 100 and a plurality of second inner fin portions 283 provided on the inner surface 28b of the second side wall portion 28 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 to remove it from the glass channel 100, the first inner fin portion 275 and the second inner fin portion 283 resist the force in the removal direction, thereby preventing the glass panel 10 from removing from the glass channel 100.

[0041] Because the first inner fin portion 275 of the glass channel 100 is located on the base end side of the first side wall portion 27, when the outer peripheral end of the glass panel 10 is inserted 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. Compared to when the first inner fin portion 275 is located on the tip end side of the second side wall portion 28 or in the vicinity of the second inner fin portion 283, frictional resistance when inserting the glass panel 10 into the glass channel 100 is reduced, allowing for smoother insertion.

[0042] 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 tries to turn back in the direction of the coming out. At this time, the second inner fin portion 283 comes into contact with the protrusion 284 and is prevented from turning back. This makes it possible to prevent the glass panel 10 from coming out of the glass channel 100.

[0043] The shapes and combinations of the components shown in the above-described embodiments are merely examples, and various modifications can be made based on design requirements, etc., within the scope of the present disclosure.

[0044] For example, in the embodiment described above, the hardness of the first resin forming the base portion 21 and the first side wall portion 27 is higher than the hardness of the second resin forming the second side wall portion 28, the outer fin portion 272, the first inner fin portion 275, and the second inner fin portion 283, but this is not limited to this. All portions of the glass channel 100 may be formed from resins of the same hardness.

[0045] In the embodiment described above, the first inner fin portion 275 and the second inner fin portion 283 are provided on the grease channel 100, but this is not limitative. The grease channel 100 does not necessarily have to be provided with the first inner fin portion 275 and the second inner fin portion 283.

[0046] In the above embodiment, a sliding window has been described as an example, but this is not limited to this. Swing doors and fixed windows can also be used. In the case of a fixed window, the frame-shaped members correspond to the upper frame, lower frame, vertical frame, etc. [Explanation of symbols]
