Description

  The present invention relates to a gasket that is attached to a panel mounting groove of a shoji paper bag and holds an edge of a panel such as glass.

  FIG. 3 is a cross-sectional view of a heel portion of a conventional building sash sliding shoji. The flange 90 has a panel mounting groove 91 opened on the inner peripheral side. The edge of the panel 92 made of glass or the like is inserted into the panel mounting groove, and between the both sides of the panel and the side wall of the panel mounting groove. Backup materials 93 and 93 are mounted in the gaps, respectively, and sealing materials 94 and 94 are filled from above the backup material to seal the gap between the side wall of the panel mounting groove and the panel. Thus, conventionally, since it is necessary to attach a backup material to both sides of the panel, it takes time to hold the panel in the panel mounting groove.

  In a shoji such as a sash for a house, a structure in which the edge of the panel is held in the panel mounting groove via a glazing channel having a U-shaped cross section and a sealing work is not required is also common. However, in that case, performances such as watertightness, airtightness, and sound insulation are inferior to the structure in which the panel is held by the backup material and the sealing material as described above. Moreover, since a part of glazing channel is exposed to the inner peripheral side of the ridge, it does not look good.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a gasket capable of improving workability when holding a panel in a panel mounting groove.

To achieve the above object, the gasket of the present invention includes a main body portion having a groove bottom abutting portion that abuts against a groove bottom of the panel mounting groove of the bag, and extends outwardly upward from the upper portions on both sides of the main body portion. become the edges of the panel from the two panels holding piece which holds the interior outward, which attached to the panel mounting groove stile, the panels holding pieces are elastically deformable in the chamber outwardly, panel mount It is in contact with the side wall of the groove at a substantially vertical surface, has a seal receiving portion at the tip, has a tapered surface inclined so as to spread upward on the opposing surface of the upper end, and is in the panel mounting groove. The distance between both panel holding pieces when attached is smaller than the thickness of the panel.

When the gasket of the present invention is pushed into the panel mounting groove of the bag, the two panel holding pieces on the indoor side and the outdoor side are greatly bent inward from the base of the main body, and elastically deformed in a direction in which the interval between the two becomes narrow , It can be easily inserted into the panel mounting groove without being caught by the inward projection on the panel mounting groove inlet side, and when inserted, the groove bottom abutting part contacts the groove bottom of the panel mounting groove , and both panel holding pieces are elastic. Therefore, it is stably held in the panel mounting groove only by the gasket. When installed, the distance between the panel holding pieces is smaller than the panel thickness, so simply inserting the panel into the gap between the two panel holding pieces elastically deforms the tip of the panel holding piece and presses it against the interior and exterior surfaces of the panel. The panel can be held stably. Moreover, since the opposing surfaces of the upper end portions of the two panel holding pieces have a tapered surface that is inclined so as to spread upward, it is easy to fit the panel into the gasket disposed in the panel mounting groove. Further, since the gasket of the present invention has a seal receiving portion at the tips of both panel holding pieces, the backup material of the panel holding piece is not attached separately between the indoor / outer surface of the panel and the side wall of the panel mounting groove. It is possible to fill the sealing material from above. Since the panel can be mounted after the gasket is first installed in the panel mounting groove, the workability is good.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 is a cross-sectional view of a gasket 10 according to an embodiment of the present invention. FIG. 1 uses this gasket 10 to hold a glass panel 9 in the panel mounting groove 2 of the shoji 1. It is a cross-sectional view which shows the procedure at the time of doing in order.

This gasket 10 is formed by extruding a synthetic resin such as a vinyl chloride resin into a rod shape. As shown in FIG. 2, as shown in FIG. 2, a substantially inverted U-shaped main body portion 11 and upper portions on both side surfaces of the main body portion 11. It has the indoor side panel holding piece 5a and the outdoor side panel holding piece 5b which protruded upwards from the position. The lower part of the main body part 11 becomes a groove bottom contact part 4 that contacts the groove bottom 3 of the panel mounting groove 2 of the bag, and the upper surface of the main body part 11 is formed flat and receives the small edge surface of the panel 9. It is a receiving part 12.
The indoor side panel holding piece 5a and the outdoor side panel holding piece 5b are formed symmetrically, and the indoor side is a substantially vertical surface that contacts the side wall 7a of the panel mounting groove on the indoor side of the indoor side panel holding piece 5a. The side wall abutting portion 8a has an outdoor side wall abutting portion 8b which is a substantially vertical surface abutting the side wall 7b of the panel mounting groove on the outdoor side of the outdoor panel holding piece 5b. Tapered surfaces 13, 13 that are inclined in an inverted C shape from 8 a, 8 b to the main body 11 are provided. The distance B between the side wall abutting portions 8a, 8b of both panel holding pieces 5a, 5b is slightly larger than the distance between the side walls 7a, 7b of the panel mounting groove 2. Further, the panel holding pieces 5a and 5b have projecting portions 14 and 14 projecting toward the upper ends of the panel holding pieces 5a and 5b, and the tapered surfaces are inclined so as to spread upward at the tip portions of the projecting portions 14 and 14. 19, 19. The distance A between the panel holding pieces 5 a and 5 b is slightly smaller than the thickness of the panel 9. A seal receiving portion 6 is provided horizontally at the tip of each panel holding piece 5a, 5b. Between the inner side surface of each panel holding piece 5a, 5b and the upper surface of the main body 11, a groove portion 15 cut downward in a triangular shape is provided so that the panel holding pieces 5a, 5b face inward. It is easy to elastically deform. Both panel holding pieces 5a and 5b are attached to the panel mounting groove 2 if they are formed outwardly and in a state before being mounted to the panel mounting groove 2 as shown by a two-dot chain line in FIG. Can be held in the groove more stably.

Next, a procedure for holding the panel 9 in the panel mounting groove 2 of the flange 1 using the gasket 10 will be described with reference to FIG. After the gasket 10 is cut in accordance with the vertical dimension of the panel 9 to be attached, the groove bottom abutting portion 4 is directed to the groove bottom 3 of the panel mounting groove 2 of the flange 1 as shown in FIG. In the state, it is pushed into the panel mounting groove 2. At this time, taper surfaces 13 and 13 are provided in an inverted C shape on the lower side of both panel holding pieces 5a and 5b, and between the inner side surface of each panel holding piece 5a and 5b and the upper surface of the main body 11. By providing the groove portions 15 and 15 having a triangular cross section, both panel holding pieces 5a and 5b are elastically deformed so as to bend inwardly from the root so that they are caught by the inward protruding portion 16 on the inlet side of the panel mounting groove 2. Without this, the gasket 10 can be easily inserted into the panel mounting groove 2.
When the gasket 10 is further pushed into the panel mounting groove 2, as shown in FIG. 1B, both panel holding pieces 5a and 5b are restored by elasticity, and the indoor side wall abutting portion 8a and the outdoor side wall abutting portion are restored. 8b contacts the side walls 7a and 7b of the panel mounting groove 2, and the groove bottom contact portion 4 contacts the groove bottom 3 of the panel mounting groove 2, so that the gasket 10 is stably held in the panel mounting groove 2. The At this time, the distance A between the panel holding pieces 5a and 5b is larger than the state before the panel mounting groove 2 is mounted by the side wall contact portions 8a and 8b contacting the side walls 7a and 7b of the panel mounting groove 2. It becomes slightly narrower, and the interval A is surely smaller than the thickness of the panel 9.
Next, when the edge of the panel 9 is pushed into the space A between the panel holding pieces 5a and 5b, the protrusions 14 and 14 at the tips of the panel holding pieces 5a and 5b are crushed as shown in FIG. The panel 9 is in pressure contact with the indoor side surface and the outdoor side surface, the small face of the panel 9 comes into contact with the receiving portion 12 of the gasket main body 11, and the edge of the panel 9 is elastically held by the gasket 10. When the edge of the panel 9 is pushed into the space A between the panel holding pieces 5a and 5b, the tapered surfaces 19 and 19 are provided at the front ends of the panel holding pieces, so that the panel 9 can be inserted into the space A. Easy to do. Since the groove-shaped space portions 17 and 17 are formed by the seal receiving portions 6 and 6 of the panel holding pieces at the entrance portions of the panel mounting groove 2 on the indoor side and the outdoor side of the panel 9, the backup material is attached separately. Even if it is not, the space portions 17 and 17 can be filled with the sealing materials 18 and 18 to be sealed, thereby obtaining high water tightness and air tightness. The panel holding pieces 5a and 5b are elastically held between the both side surfaces of the panel 9 and the both side walls 7a and 7b of the panel mounting groove 2, and the bottom surface of the panel 9 and the groove bottom 3 of the panel mounting groove 2 are provided. Since the gasket main body 11 is interposed between the two, sound insulation is improved.

  As described above, the gasket 10 is mounted in the panel mounting groove 2 in advance, and the edge of the panel 9 is simply pushed into the space A between the panel holding pieces 5a and 5b of the gasket. Since the panel 9 can be held and the seal holding portions 6 and 6 are provided at the front ends of the panel holding pieces, the seal materials 18 and 18 can be filled without separately attaching the backup material. The fitting into the mounting groove 2 and the fixing work can be performed very easily.

  The present invention is not limited to the embodiments described above. Here, although the thing for heels was demonstrated, it can use also for an upper eyelid and a lower eyelid. The material of the gasket, the panel holding piece, the fine shape of the main body, and the like can be changed as appropriate. The receiving portion for receiving the small edge surface of the panel is not always necessary, and a gap may be formed between the small edge surface of the panel and the gasket main body portion.
