Description

  The present invention relates to a lower frame flat sash for an outdoor opening, which is installed at an outdoor opening of a building and has a substantially flat upper surface formed entirely on the lower frame.

  Conventionally, on a lower frame of a sash installed in an outdoor opening of a building, a rib-shaped rail for rotating a door wheel provided on a lower frame of the sash to slide the sash constituting the sash left and right. A part is formed.

  Normally, the rail groove sectioned by the rib-shaped rail portion and the rail portion of the inner sash and the outer sash is formed with a step so that the indoor side is higher than the outdoor side from the viewpoint of sash rain. ing. That is, rainwater sprayed on the shoji or window glass falls along the shoji or window glass and accumulates in the rail groove of the lower frame, but a step is provided such that the rail groove is higher on the indoor side than on the outdoor side. The rainwater accumulated in the rail groove prevents the rainwater from entering the indoor side due to its own weight, and the rainwater accumulated in the rail groove is discharged outside.

  On the other hand, in recent years, from the viewpoint of barrier-free or universal design, a lower frame flat sash in which a rib-shaped rail portion is disposed substantially flat without providing a step between the indoor side and the outdoor side, and furthermore, the rail portion is formed in a rib shape. Also, a lower frame flat sash in which the upper surface of the rail portion is made substantially flat has been developed (for example, see Patent Document 1).

In particular, in the lower frame flat sash in which the upper surface of the rail portion is made substantially flat, it is an issue to secure a certain level of watertightness and airtightness. In Patent Document 1, rainwater is prevented from entering the room. For this purpose, an isobar structure is used to make the space between the shoji and the lower frame airtight through a horizontal tight material. Specifically, a hanging piece (sliding piece) is formed on the indoor side of the shoji lower frame, and the hanging piece and the horizontal tight material provided on the indoor side wall of the rail groove of the lower frame provide watertightness and airtightness. (For example, see Patent Document 1).
Patent No. 333058 (6 pages, FIG. 1)

  However, securing the watertightness and airtightness only by the hanging pieces on the indoor side of the above-mentioned shoji lower frame and the horizontal tight material has the following problems.

  First, since the hanging pieces (sliding pieces) are formed only on the indoor side, rainwater sprayed on the inner sash 1 and the outer sash 2 and the window glass 3 as shown in a range surrounded by a dotted line in FIG. Are invaded from the outdoor side below the lower sliding door frames 1a, 2a and accumulate on the upper surfaces 4, 5 of the lower frame rail portions located above the tight line formed by the lower sliding rails 1c, 2c and the horizontal tight material 76. Since it is easy, the burden of the horizontal tight material 76 is large, which is disadvantageous for watertightness.

  Secondly, since rainwater infiltrates and accumulates on the lower frame rail upper surfaces 4 and 5, the watertightness and airtightness of the lower part of the outside of the mating frame of the sliding sash 1 and the like and the bottom of the frame are reduced. It is difficult to secure.

  Third, as shown in a range surrounded by a dotted line in FIG. 18A, dust and dust easily accumulate on the lower frame rail upper surfaces 4 and 5, and the lower frame rail upper surfaces 4 and 5 where these are accumulated are shoji. When the door wheel 6 moves, the rail upper surfaces 4 and 5 that are easily noticeable are finely scratched, and it is necessary to frequently perform maintenance such as repair and replacement from the viewpoint of beauty and the like.

  Fourth, since the hanging pieces are not formed on the outdoor side of the inner sash and the outer sash, as shown in FIG. 19a, the bottom of the inner sash and the outer sashes lower frame 1a, 2a and the lower frame rail portion from the outdoor side. A crowbar 7 or the like is inserted into the gap between the upper surfaces 4 and 5, and the sash is lifted to remove the inner sash and the outer sash 1 and 2, thereby facilitating intrusion from outside. Accompanied.

  In addition, since a gap is formed between the vertical frame of the shoji screen (door-stop frame) and the vertical frame of the sash with which it comes into contact, there has been a problem in terms of waterproofness and security of this portion.

  Accordingly, a main object of the present invention is to provide a lower frame flat sash for external opening which has high watertightness and airtightness and is excellent in maintenance and security.

<Lower frame structure>
As shown in FIG. 5A, the lower frame 10 is provided with a first rising piece 13 and an inner sash for rotating a door wheel 31 provided on the inner sash 30 when the sash lower frame is viewed from the indoor side to the outside. The rail part 11, the second rising piece 14, the rail part 12 for the sliding door for the door wheel 46 provided on the sliding door 40 to rotate, and the third rising piece 15 are formed.

  As shown in FIG. 5A, the inner side guide groove 16 of the inner side hanging piece 32 of the inner sash door and the inner side side surface of the rail part for the inner sash are formed by the inner side rail side inner side face 11 b and the first rising piece 13. 11c and the second rising piece 14 form the outdoor guide groove 17 of the outdoor hanging piece 33 of the inner sash. Note that hatched portions in FIG. 5A indicate drainage holes, dew condensation holes, and notches, which will be described later, and FIG. 5B illustrates a partial cross section of the drainage hole 20a.

  The indoor side guide groove 18 of the indoor side hanging piece 47 of the sash, the rail indoor side surface 12c for the sash and the third rising piece are formed by the rail side indoor side surface 12b for the sash and the second rising piece 14. 15 together with the outer side guide groove 19 of the outer side hanging piece 48 of the outer sash.

  In order to make the space between the indoor hanging piece 32 of the inner sash and the first rising piece 13 and the space between the indoor hanging piece 47 of the outer sash and the second rising piece 14 airtight and watertight, A tight material 76 is provided, and a part of a tight line in the lower frame 10 is formed by sliding and tight contact between the horizontal tight material 76 and the respective indoor side hanging pieces 32 and 47.

  Here, the second rising piece 14 divides a guide groove 17 and a guide groove 18 which also function as drain grooves, as shown in FIG. 5A. Since the upper surface 14a of the second rising piece 14 is a flat surface and the lateral tight material 76 for the sash is attached thereto, a substantial tight line of the sash 40 is formed. Preferably, the horizontal tight material 76 is also flush with the upper surface 14a.

  Further, drainage holes 20a for draining rainwater accumulated in the guide grooves, which also function as drainage grooves, are provided in the lower frame indoor outer guide grooves 17, 19 for the inner and outer shojis and the inner side guide grooves 18 for the outer shojis. , 20c, 20d, and 20e are formed, and the rainwater that has fallen into the drain holes 20a, 20c, 20d, and 20e flows down into a hollow portion 21 formed in the lower frame. Eventually, rainwater will be discharged to the outside through the communication with the outside. Similarly, the condensed water is discharged outside through the condensed water drain valve 20g and the drain port 22 by the dew water hole 20f.

Here, the relationship between the outdoor-side hanging piece 33 of the inner sash and the outdoor-side guide groove 17 and the relationship between the outdoor-side hanging piece 48 of the outer sash and the outdoor-side guide groove 19 will be described in detail with reference to FIG.
A gap between the upper end of the outdoor guide groove 17 of the outdoor hanging piece 33 of the inner sash formed by the rail outer side surface 11c for the inner sash and the second rising piece 14, and the rail outer side surface for the outer sash The gap (the length of f and m shown in FIG. 21) at the upper end of the outdoor guide groove 19 of the outdoor hanging piece 48 of the outer sash formed by the 12c and the third rising piece 15 is the outdoor guide. The width of the bottoms of the grooves 17 and 19 in the indoor and outdoor directions (the lengths of g and n shown in FIG. 21) is formed to be smaller than the width of the outdoor hanging piece 33 of the inner sash and the outer hanging piece 48 of the outer sash. The lower end is inserted only so as to be located below the upper end portions of the outdoor guide grooves 17 and 19 (the upper surface 14a which is the upper end portion of the second rising piece 14 and the upper end portion of the third rising piece 15). Configuration.

  Then, of the gap (the length f shown in FIG. 21) of the outdoor guide groove 17 of the outdoor hanging piece 33 of the inner sash, the upper end of the second rising piece 14 and the outdoor hanging piece 33 The distance between the outer side surface (length of h shown in FIG. 21) is 0.3 to 6 mm. The distance between the upper end of the rising piece 14 and the lower end of the outdoor hanging piece 33 is 2 to 30 mm. Of the gap (length m shown in FIG. 21) at the upper end of the outdoor guide groove 19 of the outdoor hanging piece 48 of the outer sash, the upper end of the third rising piece 15 and the outdoor surface of the outdoor hanging piece 48 (The length of p shown in FIG. 21) is 0.3 to 6 mm, and the length of the outside hanging piece 48 (length of q shown in FIG. 21) of the outer sash is the third. The distance between the upper end of the rising piece 15 and the lower end of the outdoor hanging piece 48 is 2 to 30 mm.

  Due to these configurations and lengths, the rainwater sprayed on the lower portions of the lower frames and the like of the inner and outer sashes 30 and 40 is supplied to the upper end portions of the outdoor-side guide grooves 17 and 19 (the upper surface 14 a which is the upper end portion of the second rising piece 14, 3 (upper end of the rising piece 15) and the outside and outside hanging pieces 33 and 48 of the inner and outer shojis 30 and 40 to lose the invasion (kinetic) energy, thereby directly entering the outside guide grooves 17 and 19. Is rejected. As a result, most of the rainwater loses invasion (kinetic) energy, and most of the rainwater flows down the outdoor guide grooves 17, 19 due to the weight of the rainwater itself along the outdoor hanging pieces 33, 48. Even if it collides with the rainwater collected in the bottom surfaces of the guide grooves 17 and 19 and the outdoor guide grooves 17 and 19, there is little splash and there is little possibility that the splash will enter the indoor side. Therefore, drainage is substantially performed by the outdoor-side hanging pieces of the inner and outer sashes 30 and 40.

  Here, between the upper end of the second rising piece 14 and the outdoor surface of the outdoor hanging piece 33 of the inner shoji (length h shown in FIG. 21), and the upper end of the third rising piece 15 and the outer shoji The distance between the outdoor hanging piece 48 and the outdoor surface (the length of p shown in FIG. 21) loses intrusion (kinetic) energy and flows down along the outdoor hanging pieces 33 and 48 by the weight of the rainwater itself. From the viewpoint of efficiently leading to the outdoor-side guide grooves 17, 19, the thickness is preferably 0.5 to 4 mm, and more preferably 0.5 to 3 mm. The swallowing length (i and q shown in FIG. 21) is preferably 2 to 7 mm for the same reason, and more preferably 3 to 7 mm from the viewpoint of easy opening and closing of the sash.

  Also, in the event that rainwater that has flowed down collides with the bottom surfaces of the outdoor-side guide grooves 17 and 19 and the rainwater collected in the outdoor-side guide grooves 17 and 19, the splash does not enter the indoor side. In this case, the distance between the indoor side surfaces of the outdoor side hanging pieces 33, 48 and the upper ends of the rail side outdoor side surfaces 11c, 12c (the lengths of k and r shown in FIG. 21) should be 1-2 mm. preferable.

  As shown in FIG. 21, the upper ends of the rail outdoor side surfaces 11c and 12c have a sectional shape in the horizontal direction from the rail outdoor side surfaces 11c and 12c toward the indoor side surfaces of the outdoor hanging pieces 33 and 48. By protruding, as shown in FIG. 21, the lower part of this protruding portion and the indoor side surfaces of the rail outdoor side surfaces 11c and 12c and the outdoor hanging pieces 33 and 48 are surrounded on three sides and opened downward. Space is created. The existence of this space prevents the raindrops 33 and 48 flowing down by their own weight along the outdoor surfaces of the outdoor hanging pieces 33 and 48 from flowing into the indoor side surfaces, and the outdoor hanging pieces 33 and 48. Rain water is easily dropped from the lower end of the vehicle, and as a result, the effect of preventing rain water from entering the indoor side is exhibited. Further, by forming the upper end portions of the rail-side outdoor side surfaces 11c and 12c to protrude, the gap between the outdoor side hanging pieces 33 and 48 and the indoor side surface can be narrowed, and the intrusion of the splash can be reduced by the projecting portions. Can be blocked at the bottom. Therefore, from the above viewpoint, as shown in FIG. 21, it is preferable that the upper end portions of the rail-portion-side outer side surfaces 11c and 12c have a protruding shape.

  That is, in the sash structure according to the present invention, since the outdoor hanging pieces 33 and 48 are provided on the inner sliding door frame 36 and the outer sliding door lower frame 41, the outdoor hanging pieces 33 and 48 serve as substantial drainers. Although it functions, even if rainwater enters the upper surfaces 11a, 12a of the rails, the rainwater does not leak into the room due to the indoor side hanging pieces 33, 47 and the horizontal tight material 76, and the rainwater flows into the lower frame indoor side guide groove 16. , 18 and is discharged to the outside through the hollow portion 21. In other words, as shown in FIG. 16, the dual structure in which the draining line 84 and the tight line 85 are separately provided reduces the load on the tight line 85 and increases watertightness and airtightness.

  The lower frame 10 is made of an aluminum alloy or the like, and the lower frame itself is formed by an extruded member. As a configuration of the lower frame 10, as shown in FIG. 5A, when the upper surfaces 11a and 12b of the lower frame rail portion are formed separately from the lower frame member 23 forming the base of the lower frame, that is, the upper surface 11a of the rail portion. , 12a are separately manufactured from the upper surface component members 24, 25 of the lower frame rail portion which are detachable, and after completion, each of the upper frame member 24e, 11f of the lower frame member 23 and the rising portion 12e for the outer sash member. , 12f. If the upper surface constituent members 24 and 25 are separate members, as shown in FIG. 8, not only the drain holes 20b and 20d and the dew water hole 20f can be easily provided in the lower grooves 11d and 12d of the rail portion. It is possible to clean dust and the like clogged in the drain holes 20b and 20d and the dew condensation water hole 20f to prevent water leakage into the room due to clogging. Further, an unsanitary state due to accumulation of trash and the like can be prevented.
