Description

The present disclosure relates to edge retaining members for glass panels and fittings .

Conventionally, glass panels for building fixtures are attached to glass grooves formed in frame-shaped components such as stiles and frames by fitting the edges of the glass panel into edge-retaining members such as glazing channels. Patent Document 1 describes a method in which positioning and retaining fins engage with steps formed on the inner surfaces of the side walls of the glass groove, making it difficult for the edge-retaining members to come out of the glass groove.

Japanese Patent Application Laid-Open No. 2017-179895

The positioning and holding fin portion in Patent Document 1 extends from the side of the end holding member outward in the direction of the glass groove width. Therefore, when inserting and attaching the end holding member into the glass groove, the positioning and holding fin portion may interfere with the side wall of the glass groove, making insertion difficult.

The present disclosure has been made in consideration of the above circumstances, and provides a glass panel end retaining member and fitting that is easy to insert into a glass groove when attaching a glass panel to a frame-shaped member, and is difficult to remove once attached.

An edge retaining member for a glass panel according to one aspect of the present disclosure comprises a base portion arranged along the edge face of a glass panel, and a side wall portion extending from the indoor/outdoor end of the base portion along the plate surface of the glass panel, the outer surface of the side wall portion being provided with an outer fin portion extending outward in the groove width direction of the glass groove of a frame-shaped member to which the glass panel is attached, and a recess portion recessed inward in the groove width direction, the outer fin portion being deformable between a first position where it is engaged with the glass groove and a second position where it is accommodated in the recess, and the distance from the base end of the side wall portion to the recess is more inward in the groove width direction than the outer fin portion in the second position .

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 below) 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°.

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, when the outer edge of the glass panel 10 is inserted into the glass groove 17 with the glass channel 100 attached to the outer 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 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 bottom 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 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.

The hardness of the second resin forming the first inner fin portion 275 and 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 first side wall portion 27. As a result, when inserting the outer peripheral edge of the glass panel 10 into the glass channel 100, the first inner fin portion 275 and second inner fin portion 283 are easily deformed, making insertion easier.

The first inner fin portion 275 provided on the inner surface 27b of the first side wall portion 27 of the glass channel 100 and the multiple 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 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 coming out direction, thereby preventing the glass panel 10 from coming out of the glass channel 100.

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 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.

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.

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., without departing from the spirit of this disclosure.

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 gray channel 100 may be formed from resin of the same hardness.

In the embodiment shown above, the gre channel 100 is provided with a first inner fin portion 275 and a second inner fin portion 283, but this is not limited to this. The gre channel 100 does not necessarily have to be provided with a first inner fin portion 275 and a second inner fin portion 283.

In the above embodiment, a sliding window has been used 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.
