Description

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

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

  Normally, the rail groove defined by the rib-shaped rail portion and the rail portion of the inner and outer shoji is formed with a step so that the indoor side is higher than the outdoor side from the viewpoint of raining the sash. ing. In other words, the rainwater sprayed on the shoji and the window glass falls along the shoji and the window glass and collects in the rail groove of the lower frame, but a step is provided so that the rail groove is higher on the indoor side than the outdoor side. Since it is formed, the rainwater collected in the rail groove prevents the rainwater from entering the indoor side, and the rainwater collected in the rail groove is discharged to the outside.

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

In particular, in the lower frame flat sash with the upper surface of the rail portion being substantially flat, it has been a problem to ensure a certain level of water tightness and air tightness. Patent Document 1 prevents rainwater from entering the room. In order to prevent this, an isobaric structure is adopted in which the space between the shoji and the lower frame is airtight via a lateral tight material. Specifically, a hanging piece (sliding piece) is formed on the indoor side of the shoji lower armpit, and this hanging piece and a horizontal tight material provided on the indoor side wall of the rail groove of the lower frame provide water tightness and air tightness. (See, for example, Patent Document 1).
Japanese Patent No. 333058 (6 pages, Fig. 1)

  However, there are the following problems in securing the watertightness and airtightness only by the hanging piece on the indoor side of the above shojishige and the lateral tight material.

  First, since drooping pieces (sliding pieces) are formed only on the indoor side, as shown in the range surrounded by the dotted line in FIG. 17a, rainwater sprayed on the inner shoji 1, the outer shoji 2 and the window glass 3 Enters from the outdoor side of the lower part of the shoji lower armor 1a, 2a, and accumulates on the upper surfaces 4, 5 of the lower frame rail portion located above the tight line formed by the shoji armpit hanging pieces 1c, 2c and the lateral tight material 76. Since it is easy, the burden of the said transverse tight material 76 is large, and it is disadvantageous for watertightness.

  Secondly, rainwater invades and accumulates on the upper surface 4 and 5 of the lower frame rail portion, so that the water-tightness and air-tightness at the lower outside portion of the summoning sash 1 such as the inner sash 1 of the sliding sash and the bottom of the heel It has become difficult to secure.

  Third, as shown in a range surrounded by a dotted line in FIG. 18a, dust and dust easily collect on the upper surface 4 and 5 of the lower frame rail portion. As a result, the rail top surfaces 4 and 5 that are easily visible to the human eye are subject to fine scratches, and it is necessary to frequently perform maintenance such as repair and replacement from the viewpoint of aesthetics.

  Fourthly, no drooping piece is formed on the outside of the inner and outer shoji, so as shown in FIG. 19a, the bottom and lower frame rails of the inner and outer shoji 1a and 2a The bar 7 or the like is inserted into the gap between the upper surfaces 4 and 5 and the shoji is lifted to remove the inner shoji and the outer shoji 1 and 2 so that the intrusion from the outside is easy. Accompanying.

  In addition, since a gap is generated between the inner shovel vertical ridge (door-end ridge) and the sash vertical frame with which it abuts, this also causes problems in terms of water-stopping and crime prevention.

  Then, the main subject of this invention is providing the lower frame flat sash for external opening which is high in watertightness and airtightness, and was excellent in maintenance and crime prevention.

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, rainwater sprayed on the lower part of the inner and outer shojis 30 and 40, such as the lower arm of the inner and outer shojis 40 and 40, is the upper ends of the outdoor guide grooves 17 and 19 (the upper surface 14a that is the upper end of the second rising piece 14, 3 and the outer side hanging pieces 33 and 48 of the internal and external shovels 30 and 40 and the invasion (kinetic) energy is lost, thereby directly entering the outdoor guide grooves 17 and 19. It is refused. As a result, most rainwater loses intrusion (kinetic) energy, and most of the rainwater flows down to the outdoor guide grooves 17 and 19 due to the weight of the rainwater itself along the outdoor hanging pieces 33 and 48. Even if it collides with the rainwater accumulated in the bottom surfaces of the guide grooves 17 and 19 and the outdoor guide grooves 17 and 19, the splash is small and the risk of the splash entering the indoor side is small. Accordingly, the drainage is substantially performed by the outdoor hanging pieces of the inner and outer shoji 30 and 40.

  Here, between the upper end portion of the second rising piece 14 and the outdoor side surface of the outdoor hanging piece 33 of the inner limb (length of h shown in FIG. 21), and the upper end portion of the third rising piece 15 and the external obstacle. 21 between the outdoor side drooping piece 48 and the outdoor side surface of the outdoor drooping piece 48 (p length shown in FIG. 21) is the one that loses intrusion (kinetic) energy and flows down along the outdoor drooping pieces 33 and 48 due to its own weight. From the viewpoint of efficiently leading to the outdoor guide grooves 17 and 19, 0.5 to 4 mm is preferable, and more preferably 0.5 to 3 mm. The indentation length (i and q lengths 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 ease of opening and closing the sash.

  In the unlikely event that splashed rainwater collides with rainwater accumulated in the bottom surfaces of the outdoor guide grooves 17 and 19 or the outdoor guide grooves 17 and 19, the splashes do not enter the indoor side. Therefore, the space between the indoor side surface of the outdoor hanging pieces 33 and 48 and the upper end portion of the rail outdoor side surfaces 11c and 12c (the lengths of k and r shown in FIG. 21) is 1 to 2 mm. preferable.

Create a space. Due to the existence of this space, the outdoor drooping pieces 33 and 48 flowing down due to their own weight along the outdoor side surfaces of the outdoor drooping pieces 33 and 48 are prevented from entering the indoor side surfaces, and the outdoor drooping pieces 33 and 48 are prevented. As a result, rainwater can be easily dropped from the lower end of the door, and the effect of preventing rainwater from entering the room is exhibited. Further, by forming the upper end portions of the rail-side outdoor side surfaces 11c and 12c so as to protrude, the gap between the outdoor-side hanging pieces 33 and 48 and the indoor side surface can be narrowed, and intrusion of splashes can be prevented. Can be dammed at the bottom.
