Description

  The present invention relates to an upper suspension door.

  Due to the construction error of the frame, when the shoji was lifted on the upper frame, a gap was formed between the lower frame and the lower frame, which required troublesome position adjustment to block the line of sight in the prospective direction. Therefore, as an upper suspension door that blocks the gap between the lower frame of the sliding door shoji and the lower frame, there is one disclosed in Japanese Patent Application Laid-Open No. 2007-186888. It was driven on a flat floor by projecting downward with bias. However, in the above-described upper sliding door, since the door wheel runs on a flat floor surface, the gap opening and closing member and the door wheel are urged downward by the urging member, and the shoji is run while pressing the door wheel against the floor surface. As a result, the shoji structure became complicated. Moreover, since the shoji cannot be opened and closed smoothly unless the door roller is protruded downward from the lower end of the gap opening / closing member, a gap is generated between the gap opening / closing member and the floor surface. It was not possible to block the gaze in the expected direction of shoji. Moreover, since it is a flat floor surface without a lower frame, it is necessary to attach a guide block having a substantially concave groove to the floor surface in order to reduce the swing of the shoji.

It is the simplified longitudinal cross-sectional view which shows operation | movement of the movable part of the upper suspension door by this implementation.

Below, based on drawing, embodiment of the upper suspension door by this implementation is described.
As shown in FIGS. 1A and 1B, the upper sliding door according to the present embodiment is slidable on the frame 1 composed of the upper frame 1a, the lower frame 1b, and the collar frame 1c, and on the upper frame 1a of the frame 1. It consists of a sliding shoji 2 that is suspended. Further, the lower frame 1b is provided with a groove-shaped rail groove 15 at a position facing the shoji 2, and the movable part 8 attached to the lower end of the shoji 2 is lowered by its own weight, so that the rail groove 15 enters the rail frame 15. It has become.

  The shoji 2 is formed by assembling an upper eave 2a, a lower eave 2b, and a eave 2c, and the upper eave 2a has a locking portion 3 with a roller that rotates on a horizontal axis at the upper end. The roller 2 of the locking part 3 is locked to the locked groove 4 provided in the upper frame 1a, and the bottom of the shoji 2 is lifted, so that the shoji 2 can be slid along the locked groove 4 It is lifted by. In addition, the lower rod 2b has a substantially U-shaped cross-section having a storage groove (groove) 5 downward, and an auxiliary lower rod 9 is accommodated in the storage groove 5 so as to be movable up and down, as will be described later. .

  As shown in FIGS. 2 (a) and 2 (c), the shoji 2 includes an end cap 7 attached to the lower end of the heel 2c, a movable part 8 inserted into the end cap 7 and held vertically movable, and a movable part. 8 has an auxiliary lower bar 9 that holds both ends of the longitudinal side. As shown in FIG. 2B, the end cap 7 has a housing portion 11 for the movable component 8 having a substantially rectangular tube shape and having a lower end opened. Reference numeral 17 denotes an insertion hole for the screw 10, and the screw 10 is inserted into the substantially horizontally extending tapping hole 12 provided at the longitudinal end of the lower collar 2 b as shown in FIGS. It is inserted and fastened together with the lower collar 2b. A locking claw portion 13 that protrudes toward the housing portion 11 is provided on the inner surface side of both side walls facing each other with the housing portion 11 interposed therebetween. The movable part 8 has an insertion part having a rectangular cylindrical shape at the upper part thereof, and vertical holes 14 are provided at opposing positions on the side wall forming the insertion part. Accordingly, the movable part 8 can freely move up and down within a predetermined range in the accommodating part 11 of the end cap 7, but when the movable part 8 tries to lower further by its own weight, the remaining wall part due to the vertical hole 14 in the side wall. 14 a is locked to the locking claw portion 13 of the end cap 7, and further movement is restricted, so that the movable component 8 does not fall out of the storage portion 11 of the end cap 7. Further, the lower part of the movable part 8 is provided with a groove insertion portion 16 that protrudes with a dimension slightly narrower than the groove width of the rail groove 15 of the lower frame 1b. The auxiliary lower bar 9 is shaped like a cross, is formed to have substantially the same length as the lower bar 2b, and both end portions on the long side are fixed by the movable part 8 described above. Operates following the vertical movement of. Further, since the lower rod 2b does not come into contact with the lower frame 1b and travels while only the both ends of the groove insertion portion 16 of the movable part 8 moved downward from the lower rod 2b by its own weight are guided by the groove wall of the rail groove 15, The shoji 2 can be smoothly opened and closed (see FIG. 3B).

The operation state of the lower eyelid 2b will be described based on FIGS. 3 (a) and 3 (b).
When the shoji 2 is locked in the locked groove 4 of the upper frame 1a, the movable part 8 (see FIG. 2C) moves downward together with the auxiliary lower tack 9 by its own weight in the lower arm 2b of the shoji 2. The rail 8 enters the rail groove 15 of the lower frame 1b, and the movable part 8 and the auxiliary lower bar 9 block the gap between the lower bar 2b of the shoji 2 and the lower frame 1b (see FIG. 3B). Therefore, the line of sight of the shoji 2 expected direction is cut off and the opposite side (one side or the other side in FIGS. 3A and 3B) sandwiching the shoji 2 becomes invisible, and the movable part 8 enters the rail groove 15. Then, although it is within the predetermined range, the dimensional error of the shoji 2 can be absorbed, so that the installation adjustment of the upper sliding door that requires construction accuracy due to the construction error of the frame body 1 is facilitated.

  If the upper sliding door of the present invention is inserted into the rail groove 15 of the lower frame 1b from the lower arm 2b of the shoji 2 in addition to the above embodiment, The size and shape of the movable part 8 and the auxiliary lower arm 9 are not particularly limited.
