JP 2001-20622 A JP 2001-182448 A JP 2001-182449 A

  Conventionally, in order to improve heat insulation performance, a double-layer glass in which two plate glasses are arranged with a gap therebetween and sandwiched between both peripheral portions with a sealing material or a desiccant sandwiched between them is used. In order to attach such a multi-layer glass to the sash, a grechan, which is a long member having a substantially U-shaped cross section, is wound around the peripheral edge of the multi-layer glass, and the glazing is fitted into the sash.

  Grechan has a sealing function to prevent rainwater from entering from outside the building, but rainwater may enter between the sash and Grechan due to wind pressure or the like. In addition, the sealing material sandwiched between the glasses is originally air-tight and liquid-tight, and a desiccant for maintaining the air between the plate glasses in a dry state is also used. Moisture may invade, and vapor may condense on the inner surface of the plate glass due to the temperature difference between the room and the room, resulting in cloudiness. Such cloudiness cannot be wiped from the outside.

  Therefore, conventionally, it has been proposed to drain moisture that has entered between the Grechan and the double-glazed glass as quickly as possible, thereby suppressing the intrusion of water into the gap between the glass plates and preventing fogging. ing. For example, as a standard in the industry, it is stipulated that circular drain holes with a diameter of 8 mm are provided at intervals of 50 mm on the bottom wall of Grechan.

  Further, in Patent Document 1, a plurality of slits are formed in a Grecan having a substantially U-shaped cross section formed of a hard synthetic resin so that the corner is adapted to bend when the Grechan is bent at a corner portion of the multilayer glass. It is also disclosed that this slit improves drainage. Specifically, it is disclosed that slits having a width of 1 to 5 mm are formed at intervals of 10 to 30 mm from the top of one side wall of Grechan to the bottom wall and to the top of the other side wall.

  On the other hand, Patent Documents 2 and 3 provide a space for drainage between the central portion of the edge of the double-glazed glass and the bottom wall of Grechan by providing a left and right protrusion on the inner surface of the Grechan bottom wall. And providing a perforated part for draining water at the center of the bottom wall.

  The drain holes having a diameter of 8 mm formed at an interval of 50 mm according to the industry standard have an effect of draining to some extent and can prevent a large amount of water from accumulating in the Grechan. However, since the bottom wall is usually horizontal, a small amount of water adheres to the inner surface of the bottom wall and stays for a long time. For this reason, the inside of the Grechan is not easily dried, and fogging generated inside the double glazing cannot be sufficiently prevented.

  On the other hand, in the Grechan of Patent Document 1, since the slit having a wide opening area is formed at a relatively short pitch, the inside of the Grechan is more easily dried than in the case of the aforementioned standard. However, this also has insufficient drying in the Grechan and cannot prevent fogging. Moreover, since the material is a hard synthetic resin, it is relatively difficult to form slits.

  In the case of Patent Documents 2 and 3, the situation is not changed from the above, and a small amount of water confined in the space between the double-glazed glass and the Grechan bottom wall is difficult to dry and clouding cannot be sufficiently prevented. Furthermore, mold may occur in the space.

  The present invention solves the above-mentioned problems, makes it easy to dry the inside of the Grechan, thereby preventing the occurrence of mold and the like, and sufficiently prevents fogging of the inner surface of the plate glass even when used for multi-layer glass. It is a technical problem to provide a glacan for sheet glass that can be used.

The plate glass grechant of the present invention is made of a long member made of a polymer material having a substantially U-shaped cross section, and is characterized in that a pair of left and right weakening lines extending in the longitudinal direction are formed in the lower portion of the side wall .
A second aspect of the plate glass grechant of the present invention comprises a long member made of a polymer material having a substantially U-shaped cross section, and a pair of left and right weakening lines extending in the longitudinal direction are formed in the lower portion of the side wall, A pressing piece protruding diagonally upward from a portion slightly above the weakening line on the inner surface of the side wall is formed.
In addition, in these glacans for sheet glass, a plurality of openings or slits extending from the outside of one weak line to the outside of the other weak line across the two weak lines are spaced apart in the longitudinal direction. Are preferably provided.

  The third aspect of the glass sheet for grechant of the present invention comprises a long member made of a polymer material having a substantially U-shaped cross section, and a pair of left and right weakening lines extending in the longitudinal direction are formed on the bottom wall. A plurality of openings or slits extending from the outside of the weak line to the outside of the other weak line across the two weak lines are provided at intervals in the longitudinal direction. And it is preferable that it is such a Grechan, and an opening part is a rectangular shape.
  In any of the sheet glass gleans of the present invention, it is preferable that the weakening line is a V-groove formed on the bottom wall or the lower surface of the side wall. In addition, the polymer material is preferably a soft synthetic resin or rubber. Further, it is preferable that a lip extending toward the center portion on the upper portion of the side wall and a pressing piece extending toward the center portion be formed somewhat below the lip.

  Since the Grechan of the present invention is provided with a pair of left and right weakening lines in the longitudinal direction, by making a cut in the lateral direction and putting a finger in the cut and pulling, the portion between the left and right weakening lines is peeled off Can do. In addition, a larger rectangular opening can be easily formed. Many openings can be provided in the longitudinal direction. Since the cut into the horizontal direction is made by post-processing, an opening of an arbitrary size can be formed. The whole can be cut off at a portion corresponding to the lower side of the glass. The peeled portion can be used by being wound around the plate glass with one end connected to the Grechan as it is, or can be used after being cut off. Moreover, said opening can be utilized also when it folds in order to match | combine a Grechann to the corner part of plate glass.

  When the peeled portion is used in a state where it is connected to the grechan, the portion hangs obliquely from the grechan and the free end contacts the sash. Thereby, it becomes a passage which guides the moisture in Grechan to the sash. Furthermore, in any use form, since the opening part is large open, the inside of a Grechan is easy to dry. Therefore, generation | occurrence | production of mold | fungi etc. can be prevented. And when using for multilayer glass, the cloudiness in the clearance gap between plate glass can fully be prevented.

When a plurality of openings or slits are provided in the bottom wall at intervals in the longitudinal direction extending from the outside of one weak line to the outside of the other weak line from the outside of the one weak line. Can be peeled off with the finger-hanging portion as a starting point simply by hooking and pulling a finger or a tool into the opening or slit . Therefore, it is not necessary to make a cut and the work becomes easy. In particular, in the case of a slit, one side of the slit may be pushed with a finger or the like and hooked with the finger or the like. Further, by peeling off from one opening or slit to the next finger-hanging part and further continuing to the next opening or slit as desired, a larger opening can be easily formed. Thereby, the air permeability inside and outside of Grechan can be enhanced, and the inside of Grechan is easily dried.

When the opening has a rectangular shape, the air inside and outside of the Grechann is good even if it is used as it is. If a large opening is required, a finger can be inserted through the opening as described above and then peeled off to the next opening or further to the next opening. Further, the entire range corresponding to the lower side of the glass may be peeled off.

  When the weakening line is a V-groove formed on the surface side of the bottom wall or the lower part of the side wall, molding is easy and tearing with a finger or the like is easy. When the polymer material constituting the Grechan is a soft synthetic resin or rubber, the production is easy and the tearing operation is easier. Further, it is easy to wrap around a plate glass.

  Next, an embodiment of the Grechan of the present invention will be described with reference to the drawings. 1 is a perspective view showing an embodiment of the Grechan according to the present invention, FIGS. 2a and 2b are a sectional view and a plan view of the Grechan, respectively, FIG. 3 is a perspective view showing a method of peeling the Grechan of FIG. 4b is a partially cutaway side view showing different usage states of the grechan, FIG. 5 is a front view showing a state where the grechan of FIG. 1 is attached to the plate glass, and FIG. 6 is a double glazing of FIG. FIG. 7A, FIG. 7B and FIG. 7C are cross-sectional views showing another embodiment of the Grechann of the present invention, an enlarged cross-sectional view and a plan view, respectively, FIG. 8, FIG. 9 and FIG. 10 is a cross-sectional view showing still another embodiment of the Grechan of the present invention, and FIG. 11 is a front view showing a state where the Grechan of FIG. 9 is attached to the plate glass.

  A Grechan 10 shown in FIG. 1 is a long component having a substantially U-shaped cross section, and schematically includes a bottom wall 11 and a pair of left and right side walls 12, 12 extending upward from both ends of the bottom wall. And. The side wall 12 is usually slightly inclined so that it is somewhat wider upward. A lip 13 that extends obliquely upward toward the center is provided at the upper end of each side wall 12, and the lip 13 is continuous with a locking piece 14 that extends obliquely downward toward the outside. The locking piece 14 is a portion that engages with the sash (see FIG. 6). A shallow groove 15 is formed below the locking piece 14 of the side wall 12. Further, on the inner surface side of the side wall 12, a pressing piece 16 is provided that extends obliquely downward from the lower side of the lip 13 toward the center.

  The features of the Grechan 10 are a pair of left and right V grooves 17 (see FIG. 2a) formed on the lower surface of the bottom wall 11, and a plurality of openings 18 (see FIG. 2b) formed in the bottom wall 11. The V groove 17 extends in the longitudinal direction of the Grechan 10. The V-groove 17 is a weak line for easily breaking, and can be constituted by a U-shaped groove, a square-shaped groove, a slit having no width, or the like. Further, although it is possible to form perforations, a weaker line shape in which the same cross-sectional shape is continuous is preferable for forming by extrusion molding.

  As shown in FIG. 2 b, the opening 18 has a rectangular shape, and the dimension W in the width direction is larger than the interval S between the left and right V grooves 17. Thereby, the opening 18 reaches from the outside of one V groove 17 to the outside of the other V groove 17. In this embodiment, the width W of the opening is smaller than the width W2 of the bottom wall 11. However, it may reach the lower part of the side wall 12 as will be described later. The pitch P of the openings 18 is not particularly limited, but is, for example, about 1 to 5 times the width of the openings 18. The opening 18 can be formed by extruding the Grechan 10 and then punching with a press or the like.

  Such a Grechan 10 can be manufactured by extrusion molding from various conventionally used synthetic resins or polymer materials such as rubber. As the synthetic resin, vinyl chloride elastomer, polypropylene (PP), acrylonitrile / butadiene / styrene terpolymer (ABS resin), or the like is employed. As the rubber, various synthetic rubbers such as chloroprene rubber (CR) and silicone rubber (Si) or natural rubber are used. The synthetic resin and rubber are preferably soft. Thereby, the whole including the lip 13 and the locking piece 14 can be manufactured by extruding with the same material, and the work of winding on the plate glass is easy. However, the lip 13 and the locking piece 14 may be formed by so-called two-color extrusion, such as using a soft material and the other part using a hard material.

  Even if the Grechan 10 configured as described above is used as it is, the opening 18 allows the inside (above the bottom wall) and the outside (below the bottom wall) of the Grechan 10 to communicate with each other over a wide area. Therefore, it is difficult for water droplets to accumulate inside the Grechan 10 and it is easy to dry. Further, as shown in FIG. 3, when the edge of the opening 18 is picked with a finger and pulled as indicated by an arrow R, a part of the bottom wall 11 is easily broken at the left and right V-grooves 17 and peeled off in a strip shape. Can do. Thereby, a larger continuous opening 20 can be obtained.

  That is, when the rectangular portion 21 between the two adjacent openings 18 is removed, a continuous opening 20 that is at least twice as large as the original opening 18 is obtained. Further, as shown by the arrow R2, by peeling off the adjacent rectangular portions 21 in order, three or more openings can be successively continued to form a larger continuous opening. Can do. For example, a continuous opening can be formed over the entire range corresponding to the lower side of the glass.

  Further, as shown in FIG. 4 a, the rectangular portion 21 may not be completely cut off from the remaining portion of the Grechan 10 and a part of the rectangular portion 21 may be kept continuous. 4B shows a state in which the rectangular portion 21 is completely cut off.

  The Grechan 10 configured as described above is inserted into the sash while being wound around a plate glass such as the multilayer glass 25 as shown in FIG. At that time, at the portion that is in contact with the lower edge of the glass sheet, as shown in FIG. 4a or 4b, the rectangular portion 21 is partially cut or completely cut out to form a wide continuous opening. Or after winding around the laminated glass 25, a continuous opening can also be formed. For example, in the case shown in FIG. 5, the upper side 26 of the multi-layer glass 25 is completely cut off, and the left and right side sides 27 are respectively peeled off from the lower side so that the upper end is continuous with the Grechan 10. Make sure it hangs down. On the lower side 28, one side may be continuous with the Grechan 10 or may be cut off. In a range corresponding to the lower side 28, all the rectangular portions 21 can be cut out to form a continuous opening on the entire lower side 28.

  FIG. 6 shows a state in which the Grechan 10 from which the rectangular portion 21 has been cut is attached to the multi-layer glass 25 and further fitted to the sash 30. Here, a glass liner 31 is installed on the inner surface of the sash 30, and a multilayer glass 25 around which the Grechan 10 is wound is fitted thereon. The sash 30 is a conventionally known sash 30 having a glass insertion portion 32 having a U-shaped cross section and a frame portion 33 extending below the glass insertion portion 32. Reference numeral 34 in FIG. 5 denotes a desiccant, and reference numeral 35 denotes a sealing material or caulking material that also serves as an adhesive.

  By assembling as described above, the bottom wall 11 of the Grechan 10 is supported by the bottom wall 36 of the glass insertion portion via the glass liner 31, and the vicinity of the upper end of the side wall 12 of the Grechan 10 is the upper end of the side wall 37 of the sash 30 from the outside. Supported by The sash 25 is, for example, an aluminum extrusion-molded product. The sash 25 is composed of a set of four, and after the multi-layer glass 25 around which the Grechan 10 is wound is inserted, the whole is integrated with a screw or the like. In the corner portion 38 of the multilayer glass 25, a cut is made in the Grechan 10 and the corner portion 38 protrudes from the bottom 11 of the Grechan 10, but since a large opening can be easily formed as described above, Work is easy.

  In the assembled state, as shown in FIG. 5, the rectangular portion 21 hanging from the grechan 10 comes into contact with the inner surface of the sash, so that the water droplets accumulated inside the grechan 10 travel along the rectangular portion 21 and move to the sash side. To do. And in the part of the side 27 extended in the vertical direction, it further travels down along the inner surface of the sash. Therefore, moisture can be quickly removed from the vertical Grechant 10.

  Further, not only the side 27 but also the whole including the upper side 26 and the lower side 28, a large continuous opening is formed in the bottom wall 11 of the Grechan 10, so that the inside and outside of the Grechan 1 communicate in a wide range. As a result, the inside of the Grechan 10 is easily dried. Therefore, it is possible to prevent the inside of the Grechan 10 from drying quickly even after raining, and moisture from entering the double-glazed glass 25 to cause clouding.

  1 has a V-groove 17 formed on the bottom surface of the bottom wall 11, it can also be formed below the side wall 12 as shown in FIGS. In this Grechan 40, the opening 18 is formed from the lower part of one side wall 12 to the lower part of the other side wall 17 in a range exceeding the V grooves 17 on both sides. Also in this case, if the edge of the opening 18 is picked and pulled by a finger or the like, the V-grooves 17 on both sides are broken, and the rectangular portion 21 can be easily removed up to the next opening 18. In addition, it can also be made into the state with which one part was continued.

  When the Grechan 40 formed so that the opening 18 reaches the lower portion of the side wall 12 is wound around the double-glazed glass and attached to the sash, the water in the Grechan 40 is discharged to the side as indicated by an arrow Q in FIG. It becomes easy. Thereby, for example, as shown in FIG. 8, even when the protrusion 41 that receives the lower end of the multilayer glass 25 is formed, moisture is easily discharged as indicated by the arrow Q.

  Of the pair of V grooves, one V groove 17 may be formed on the lower surface of the bottom wall 11 as shown in FIG. 1, and the other V groove 17 may be formed below the side wall 12 as shown in FIG. In the embodiment, the V groove 17 is formed on the outer surface of the Grechan, but it may be formed on the inner surface. However, if formed on the outer surface, the V-groove can be cut with a knife or the like, so the outer side is preferred. The V-groove is usually formed with a thickness that can be torn off by hand, but may be left thicker when cutting with a cutting tool such as a knife.

  The Grechan 43 shown in FIG. 9 has substantially the same cross-sectional shape as the Grechan 40 in FIG. 7A, and the V groove 17 is formed in the lower part of the left and right side walls 12. However, the bottom wall 11 is not provided with an opening (reference numeral 18 in FIG. 7a). Therefore, two slits (see reference numeral 46 in FIG. 10) reaching the left and right V-grooves 17 with a knife or the like are inserted from the bottom wall 11 side during use, and the bottom wall 11 between the slits is peeled off to form an opening. .

  The Grechan 45 shown in FIG. 10 is the same as the Grechan 43 shown in FIG. 9 except that a pressing piece 47 is formed obliquely upward from a portion slightly above the V groove 17 on the inner surface of the side wall 12. As shown in FIG. 11B, the diagonally upward pressing piece 47 is used to maintain the shape by being brought into contact with the glass when cut off from the V-groove 17. Since Grecans 43 and 45 in FIGS. 9 and 10 are not provided with an opening, they are easier to manufacture and less expensive to manufacture than Grechan 10 in FIG. 9 and 10, the V-groove 17 is formed in the side wall 12, but a V-groove can also be formed in the bottom wall 11 as in the case of the Grechan in FIG.

  The Grechan 43 in FIG. 9 (the same applies to the Grechan 45 in FIG. 10) has a slit 46 from the bottom wall 11 corresponding to the corner portion 38 of the multilayer glass 25 to the vicinity of the shallow groove 15 as shown in FIG. It is opened and used by being wound around the multilayer glass 25. The portion corresponding to the cut 46 at the upper part of the Grechan 43 (inside the frame in FIG. 11) is cut into a V shape so that the V-shaped cut surfaces come into contact with each other when bent at 90 degrees. Thereby, they do not overlap each other when bent 90 degrees. The center of the upper side of the multilayer glass 25 is a joint 49 at both ends of the Grechan 43. After mounting, the bottom wall 11 between the left and right cuts of the lower side 28 is peeled off, and the lower end edge of the multilayer glass 25 is exposed. In this way, since water does not accumulate in the entire lower side 28, there is no fear that the inside of the double-glazed glass 25 is fogged or moldy. The upper side 26 and the side side 27 of the multilayer glass 25 are not cut off. However, it may be partially cut off.

  1 and 7a and the like, the opening 18 or the slit having a lateral slit is formed so that the opening 18 and the slit extend beyond the V-groove 17, that is, across the V-groove. You may make it width. Further, it may be formed so as to stay inside the V groove 17. In the case of forming the opening 18 or the slit that stays on the inner side, it is easy to continuously cut off the inner side of the V groove 17. In addition, there is an effect of escaping water through the opening 18 or the like without being cut off.
