Description

  The present invention relates to an improvement of a sliding door device called a barrier-free sash, in which a sliding door shoji is built in a window frame having a flat upper surface of a lower frame.

  In order to ensure the ease of movement of the elderly and the physically handicapped, the structure of a window frame that is called a barrier-free sash, with the upper surface of the lower frame being flat, is described in, for example, Patent Documents 1 to 4, etc. Various types have been conventionally known. In each of the structures described in these patent documents, the outer peripheral surface of the door wheel installed on the lower arm of the sliding door is a simple cylindrical surface, and the outer surface of the door wheel is in contact with the upper surface of the lower frame. It is a surface.

  In the case of such a conventional structure, since a special thing different from what was conventionally used as a doorwheel is used, unless it spreads widely in the future, there is a possibility that the cost will increase. In particular, at present, when repairing or replacing a broken trolley, the labor and cost required for obtaining the trolley may be higher than that of a general one where concave grooves are formed on the entire circumference. There is. Further, since the engaging portion between the door pulley and the lower frame cannot position the sliding door shoji in the indoor / outdoor direction, a structure for separately positioning the sliding door shoji in the indoor / outdoor direction is necessary.

  In consideration of such circumstances, a lower frame with a lower guide rail is used as the lower frame, and the upper edge of the lower guide rail is the part of the upper surface of the lower frame where people and objects move It is advantageous to adopt a structure that is positioned below the lower part. In this case, a recess is provided on the upper surface of the lower frame in the moving direction of the sliding door shoji, and the lower guide rail is provided so as to protrude upward from the bottom surface of the recess. Accordingly, there is an opening of the recess on the upper surface of the lower frame, and the upper edge of the lower guide rail is present at the center of the opening.

  The concave portion and the lower guide rail are provided over the entire length of the lower frame, whereas the length (width) of the sliding door shoji is shorter than the total length of the lower frame. For this reason, the opening part of the said recessed part and a part of length direction of the upper end edge of a lower guide rail are exposed without being covered with the said sliding door shoji. For this reason, not only the appearance of the said part worsens, but when a foreign material falls in the said recessed part, it becomes difficult to take out this foreign material. That is, since the upper end edge of the lower guide rail exists at an approximately middle portion of the opening of the recess, the opening is divided into two in the width direction and becomes narrow. As a result, when a foreign substance such as a pin falls into the recess, it is difficult to take out the foreign substance.

  In Patent Document 5, when a shutter panel is wound up by a part of a lift guide groove for guiding both side edges of a lift-type shutter, a portion exposed below the shutter panel is covered with a band-shaped sealing material. The structure is described. However, such a structure described in Patent Document 5 is intended only to cover the opening of the groove existing in the vertical direction, and covers the upper end opening of the groove existing on the upper surface of the lower frame of the sliding door device. It is not intended to be a thing. Moreover, it is difficult to apply to a sliding door apparatus having a complicated structure such as winding a strip-shaped sealing material by a winding mechanism and having a limited installation space.

  Such cover bands 25a to 25d are each made of a stainless steel plate such as a metal plate constituting a metal tape measure, or a long material made by integrally extruding a synthetic resin. It is made of an elastic material having such a rigidity that it can be moved. In the case of the present embodiment, as each of the cover bands 25a to 25d, the one having a circular sectional shape in the free state is used, and the thickness of each of the cover bands 25a to 25d is suppressed to be small. The rigidity is ensured. The bending directions of the cover bands 25a to 25d are directions in which the upper surfaces of the cover bands 25a to 25d are convex curved surfaces in a state where the upper end openings of the recesses 15a and 15b are covered. The reason for this is to ensure the height of each of the lower guide rails 14a and 14b while preventing interference between the cover bands 25a to 25d and the upper end edges of the lower guide rails 14a and 14b.

Among the cover bands 25a to 25d as described above, the cover band 25a of the above (1) has both end portions thereof, as shown in FIGS. And is bound to Among these, the upper surface outdoor side one end part of this lower frame 4 and the one end part of the said cover belt | band | zone 25a are couple | bonded via the latching bracket 26, as shown in FIG. That is, with the locking bracket 26 fixed to the bottom surface of one end of the outdoor recess 15a with a screw 27, the upper end of the locking bracket 26 is positioned at one end opening of the outdoor recess 15a. ing. Then, one end of the cover band 25 a of (1) is coupled and fixed to the upper end of the locking bracket 26 by another screw 28 and a holding plate 29.

  On the other hand, the other end of the cover band 25a of (1) is coupled and fixed to a part of the first guide bracket 30 supported and fixed to the lower end of the butting bar 9a. That is, the first guide bracket 30 is supported and fixed to the lower end portion of the butting bar 9a by a screw 31, and the other end portion of the cover band 25a of the above (1) is attached to a partial upper surface of the first guide bracket 30.
