Abstract

PROBLEM TO BE SOLVED: To prevent the deterioration of mountability in the case of mounting a grazing channel on the circumference of glass installed in a window frame.SOLUTION: A grazing channel 14 is formed with a protrusion part 29 at a bottom wall part 24 side portion of the top end of a first lip 27. Thus, when the grazing channel 14 is obliquely fitted into a composite glass plate 13, the top end of the first lip 27 pressurized to the composite glass plate 13 can be prevented from being brought into contact with a side wall part 23 by the protrusion part 29. When the grazing channel 14 is more pushed in, the edge of the composite glass plate 13 can be butted to a position at the top end side of a second lip 28 away from the root. Thus, it is possible to reduce a power necessary for pressurizing and elastically deforming the second lip 28 by the edge of the composite glass plate 13, and to reduce a power necessary for mounting the grazing channel 14.

Description

  The present invention relates to a glazing channel mounted along the periphery of a panel (for example, glass) to be assembled in a window frame of a building or the like.

  As a window structure provided in a building, etc., the glazing channel is placed between the window frame and the glass by assembling the glass to the window frame with the glazing channel mounted along the periphery of the glass. There is one that seals between the frame and the glass.

  As an example of such a glazing channel, as described in Patent Document 1 (Japanese Patent Application Laid-Open No. 8-42258), two cross-sections are provided on the inner side surfaces of both side walls of a substantially U-shaped holding member. There is a configuration in which a guide is provided and a tongue-like piece is provided at each end of both side walls.

JP-A-8-42258

  As shown in FIG. 6, the present applicant, as a glazing channel 2 mounted along the periphery of the glass 1, has a main body part 3 having a substantially U-shaped cross section, and both side wall parts 4 of the main body part 3. A structure provided with seal portions 5 and 5 'protruding from the tip of 4', and first lips 6 and 6 'and second lips 7 and 7' protruding from the inner surfaces of both side wall portions 4 and 4 ', respectively. The glazing channel 2 has been researched and developed, but the following issues were found during the research process.

  As shown in FIG. 6, when the glazing channel 2 is attached to the periphery of the glass 1, if the glazing channel 2 is inclined with respect to the glass 1, one first lip 6 is The one wall surface of the glass 1 is pressed by the first lip 6 and the other wall surface of the glass 1 is pressed by the seal portion 5 'and the first and second lips 6', 7 '. The two wall surfaces of the glass 1 may be in contact with each other. At this time, if one of the first lips 6 pushed by the glass 1 is greatly elastically deformed until it comes into contact with the side wall portion 4, the distance between the edge of the glass 1 and the side wall portion 4 becomes very small. When the channel 2 is further pushed in, the edge of the glass 1 hits the vicinity of the root of the second lip 7. For this reason, the force required to press and elastically deform the second lip 7 at the edge of the glass 1 is increased, and accordingly, the force required to attach the glazing channel 2 is increased. There is a problem that the wearability of becomes worse.

  Therefore, the problem to be solved by the present invention is to provide a glazing channel capable of preventing deterioration of the mounting property when the glazing channel is mounted on the peripheral edge of the panel.

  In order to solve the above-mentioned problem, the invention according to claim 1 is provided with a pair of side wall portions facing each other and a bottom wall portion connecting both side wall portions that can be mounted along the peripheral edge of the panel assembled to the window frame. A main body portion, a seal portion projecting from the tip of each side wall portion, a first lip that is softer than the main body portion and projecting from the inner side surface of each side wall portion, and softer than the main body portion and inside the both side wall portions A long glazing channel having a second lip projecting from the bottom wall portion side of the first lip of the side surface, wherein the bottom lip side portion of the first lip and the side wall portion One or more ridges extending in the longitudinal direction of the main body are formed in at least one of the portions of the side surface between the first lip and the second lip.

  When the glazing channel is attached to the peripheral edge of the panel, if the glazing channel is inclined with respect to the panel, one of the first lips is elastically deformed by being pushed by the edge (corner) of the panel. The wall surface of the panel may be pressed by the first lip, and the other wall surface of the panel may come into contact with the seal portion and the first and second lips so that the both wall surfaces of the panel are sandwiched. At this time, the glazing channel of the present invention has a protrusion formed on the portion of the first lip on the bottom wall portion side and on the inner surface of the side wall portion between the first lip and the second lip. Therefore, it is possible to prevent the first lip pressed by the panel from coming into contact with the side wall portion by the ridge portion, and compared with the case where the ridge portion is not formed, the edge of the panel and the side wall portion. The interval between and can be increased. For this reason, when the glazing channel is further pushed in, the edge of the panel can be located at a certain distance from the root of the second lip to the tip side. This makes it possible to reduce the force required to press and elastically deform the second lip at the edge of the panel as compared with the case where no protrusion is formed, and attach the glazing channel accordingly. Therefore, even when the glazing channel is obliquely fitted to the panel, the glazing channel can be mounted in the correct position without deteriorating the mounting property.

  In this case, as described in claim 2, the protrusions may be respectively formed on the first lips provided on the both side walls, or may be respectively formed on the inner side surfaces of the both side walls. In this way, when the glazing channel is mounted on the peripheral edge of the panel, the first lip pressed by the panel contacts the side wall portion regardless of which side wall portion side the glazing channel is inclined with respect to the panel. This can be prevented by the protrusion.

  Moreover, you may make it a ridge part be formed in the 1st lip like Claim 3. In this way, the positional relationship between the first lip and the protrusion can be maintained constant, and the first lip contacts the side wall without being affected by the deformation of the first lip or the side wall. Can be prevented.

  Further, as described in claim 4, the protruding portion may be formed at the tip of the first lip. If it does in this way, it can prevent that the tip of the 1st lip contacts a side wall part.

By the way, when the protrusion is formed on the first lip, the rigidity of the first lip may be increased, and the first lip may not be easily elastically deformed.
Therefore, as described in claim 5, the protrusions may be formed on the inner surface of the side wall. If it does in this way, it can avoid that the rigidity of the 1st lip becomes high and the 1st lip becomes difficult to elastically deform.

Long glazing channel 14 made of a polymer material and the like mounted along the four edges. The window 11 has a glazing between the window frame 12 and the composite glass plate 13 by assembling the composite glass plate 13 to the window frame 12 with the glazing channels 14 mounted along the periphery of the composite glass plate 13. A channel 14 is disposed (see FIG. 2) to seal between the window frame 12 and the composite glass plate 13. Each of the glazing channels 14 attached to the four edges of the composite glass plate 13 on the upper, lower, left and right edges is cut at 45 °, and the terminals are brought into contact with each other at the corner of the composite glass plate 13.

  As shown in FIG. 2, a mounting groove 15 into which the outer peripheral portion of the composite glass plate 13 is fitted is formed in the inner peripheral portion of the window frame 12, and a setting block 16 is provided at the bottom of the mounting groove 15. It is partially arranged along the longitudinal direction of. The setting block 16 supports the composite glass plate 13 and secures a space for drainage in the mounting groove 15.

  In the composite glass plate 13, two glass plates 17 are arranged at a predetermined interval, and an air layer 18 is formed between the two glass plates 17. In the vicinity of the periphery between the two glass plates 17, an aluminum spacer 19 is disposed to keep the distance between the glass plates 17 constant. The aluminum spacer 19 is formed in a hollow shape, and a number of fine holes (not shown) are formed on the surface of the aluminum spacer 19 on the air layer 18 side. A desiccant 20 (for example, silica gel) that adsorbs moisture is contained.

  Further, a primary sealing material 21 (for example, butyl rubber) for preventing moisture from entering the air layer 18 is interposed between each glass plate 17 and the aluminum spacer 19, and the aluminum spacer 19 is formed by the primary sealing material 21. Is adhesively fixed to each glass plate 17. Further, a secondary sealing material 22 (for example, silicone) that suppresses deformation of the primary sealing material 21 is interposed on the outer peripheral side of the aluminum spacer 19 between the two glass plates 17, and this secondary sealing. Two glass plates 17 are bonded by the material 22.

  As shown in FIGS. 2 and 3, the glazing channel 14 has a pair of side wall portions 23 and both side wall portions facing each other by coextrusion molding of a polymer material such as rubber or a thermoplastic synthetic resin (including a thermoplastic elastomer). A main body portion 25 having a substantially U-shaped cross section having a bottom wall portion 24 for connecting 23, a seal portion 26 projecting from the tip of each side wall portion 23 and extending in a direction approaching each other, A first lip 27 that protrudes from the side surface and extends in a direction approaching each other, and a second lip 28 that protrudes from the bottom wall portion 24 side of the inner surface of both side wall portions 23 from the bottom wall portion 24 side and extends in a direction approaching each other. And are integrally formed. The bottom wall portion 24 is formed with a concave groove 24a in the central portion, and stepped portions 24b are provided on both sides thereof.

  The first lip 27 is formed in a length and a position that do not contact the second lip 28 when elastically deformed. Further, a protrusion 29 extending in the longitudinal direction of the main body 25 is formed at a portion of the tip of the first lip 27 on the bottom wall portion 24 side. In the first embodiment, protrusions 29 are formed at the tips of the first lips 27 provided on the side wall portions 23. Thereby, when the first lip 27 is elastically deformed, the protruding portion 29 prevents the tip of the first lip 27 from coming into contact with the side wall portion 23.

  The glazing channel 14 is attached to the periphery of the composite glass plate 13 by pushing the glazing channel 14 from the state in which the body portion 25 of the glazing channel 14 is put on the periphery of the composite glass plate 13. At this time, the first and second lips 27 and 28 abut against the composite glass plate 13 and elastically deform, and the elastic glass repulsive force of the first and second lips 27 and 28 presses the composite glass plate 13 to both sides. By holding the composite glass plate 13 between the first and second lips 27, 28 of the wall portion 23, the glazing channel 14 is attached and fixed to the periphery of the composite glass plate 13.

And the distance dimension Y (see FIG. 3) between the second lips 28 of the side wall portions 23 are set to be smaller than the width dimension Z (see FIG. 2) of the composite glass plate 13.

  Further, as a polymer material for forming the glazing channel 14, the main body portion 25 (the side wall portion 23 and the bottom wall portion 24) is formed of a polymer material having rigidity, and the seal portion 26 and the first and second lips 27 and 28 are formed. The protrusion 29 is made of a polymer material that is softer and more elastic than the main body 25 and is compatible with the main body 25.

  In this embodiment, for example, the main body 25 is formed of a hard vinyl chloride resin (for example, a vinyl chloride resin having a durometer hardness of HDA 100 according to JIS K7215), and the seal portion 26, the first and second lips 27, 28, and the protrusions. The portion 29 is formed of a soft vinyl chloride resin (for example, a vinyl chloride resin having a durometer hardness of HDA 60 to 70 according to JIS K7215).

  The polymer material for forming the glazing channel 14 is not limited to this, and may be appropriately changed. For example, the main body portion 25 is formed of polypropylene resin, and the seal portion 26 and the first and second lips 27, You may make it form 28 and the protrusion part 29 with an olefin type thermoplastic elastomer. Alternatively, the main body portion 25 may be formed of ABS resin, and the seal portion 26, the first and second lips 27 and 28, and the protruding portion 29 may be formed of chlorinated polyethylene or soft acrylic.

  As shown in FIG. 4, when the glazing channel 14 is attached to the periphery of the composite glass plate 13, if the glazing channel 14 is inclined with respect to the composite glass plate 13, one first lip 27 becomes the composite glass. It is pressed by the edge (corner) of the plate 13 to be elastically deformed, and one wall surface of the composite glass plate 13 is pressed by the first lip 27 and the other wall surface of the composite glass plate 13 is the first seal portion 26 'and the first wall. In some cases, both wall surfaces of the composite glass plate 13 may be sandwiched by coming into contact with the second lips 27 ′ and 28 ′. At this time, the glazing channel 14 of the first embodiment is pressed by the composite glass plate 13 because the protrusion 29 is formed at the tip of the portion of the first lip 27 on the bottom wall portion 24 side. The protrusion 29 can prevent the tip of the first lip 27 from coming into contact with the side wall 23, and compared with the case where the protrusion 29 is not formed, the edge and the side wall of the composite glass plate 13. 23 can be increased. For this reason, when the glazing channel 14 is further pushed in, the edge of the composite glass plate 13 can be located at a position away from the root of the second lip 28 to the tip side to some extent. Thereby, compared with the case where the protrusion part 29 is not formed, the force required to press and elastically deform the second lip 28 at the edge of the composite glass plate 13 can be reduced. The force required to mount the glazing channel 14 can be reduced, and even when the glazing channel 14 is fitted obliquely to the composite glass plate 13, the correct position can be obtained without deteriorating the mounting properties of the glazing channel 14. Can be attached to.
