ンテナンス性に劣るという欠点があった。In order to eliminate such inconvenience, a method has been proposed in which a gap sealing mechanism interlocking with a door knob is provided at the lower end portion of the door 3 to omit the door slide 1 which causes a pedestrian's stumbling. However, since the gap sealing mechanism has a complicated structure, the manufacturing process is complicated, so that the productivity is low, and the door 3 often operates every time the door 3 is opened and closed, which often causes a failure. It has a problem of durability, and its repair and inspection are troublesome and troublesome, so that it is inferior in maintainability.

ある。As shown in FIG. 1, the door slide 1 according to the present invention has an elongated frame body 6 having a C-shaped cross section and having an opening 5 formed therein. Two treads 7 and 8 are formed so as to sandwich the opening 5. Further, on the lower side of each tread 7, 8, a guide piece 10 having an arc cross section,
11 is installed internally. Further, the frame body 6 is provided with a cylindrical dragging member 13 via three coil springs 12, and a part of the dragging member 13 projects from the treads 7 and 8 by a predetermined amount L1. Here, the predetermined amount L1 means the amount required to close the gap below the door 3, and is, for example, 3 to 5 mm. The three coil springs 12 are provided at a plurality of places (for example, 3 to 4 places) at a predetermined pitch in the axial direction (length direction) of the sliding member 13. Also, the sliding member 1
As the material of 3, it is possible to adopt a hard synthetic resin such as a hard vinyl chloride resin or a metal such as aluminum.

る。Since the door shoe slide 1 according to the present invention has the above-described structure, as shown in FIG. 2, the door shoe slide 1 has its treads 7 and 8 flush with the surface of the floor material 2. When it is installed below the door 3 so that a part of the sliding member 13 protrudes from the treads 7 and 8 by a predetermined amount L1, the gap between the door 3 and the floor material 2 is small when the door 3 is closed. It is closed by the door slide 1 and airtightness and soundproofing are maintained.

なる。When a pedestrian opens the door 3 and passes by, as shown in FIGS. 3 (a) and 3 (b), the pedestrian's own weight is passed through the flexible sheet 15 of the door slide 1. Since the sliding member 13 acts downward, the sliding member 13 retracts and is housed in the frame body 6 against the elasticity of the coil spring 12, and as a result, a pedestrian such as an elderly person can slide the door. It is possible to prevent the occurrence of a situation in which the user stumbles over and falls.

ことはない。At this time, since the sliding member 13 has a cylindrical shape, its cross-sectional shape is circular, so that the sliding movement of the sliding member 13 is smoothly performed. Further, since the flexible sheet 15 that covers the sliding member 13 can be arbitrarily deformed due to its flexibility, it does not hinder the backward movement of the sliding member 13.

る。Immediately after the passage of the pedestrian in this way, the sliding member 13 elastically projects and returns to its original state. At this time, the guide pieces 1 having an arc cross section are provided below the treads 7 and 8.
Since 0 and 11 are provided inside, the protruding operation of the sliding member 13 is smoothly performed. Therefore, airtightness and soundproofing can be maintained at all times when the door 3 is closed.

も優れる。By the way, since the flexible sheet 15 is covered on the upper side of the sliding member 13 and the treads 7 and 8, dust enters the frame 6 through the gap between the sliding member 13 and the treads 7 and 8. Since it does not enter and the door slide 1 is structurally simple, it is excellent in productivity, durability, and maintainability.

様、沓摺部材１３の後退動作は円滑に行なわれる。Although the case where the cylindrical sliding member 13 is used has been described in the above embodiment, even if the sliding member 13 is cylindrical, the cross-sectional shape is the same in that it is circular. Therefore, as in the case of the cylindrical sliding member 13, the sliding movement of the sliding member 13 is smoothly performed.
【００１８】また、上述の実施形態においては弾性伸縮

支持するようにすればよい。Further, although the case where the coil spring 12 is used as the elastic expansion / contraction member has been described in the above-described embodiment, an elastic expansion / contraction member other than the coil spring 12 can be adopted. For example, as shown in FIG. 4 and FIG.
The arc-shaped leaf spring 16 may be used as the elastic member. In this case, as shown in FIG. 5, both legs 16a of the leaf spring 16 may be supported on the support base 17 so as to be slidable in the horizontal direction.

る。As described above, according to the present invention, there is a frame body 6 having a C-shaped cross section in which an opening 5 is formed, and the tread surface 7 is formed so that the opening 5 is sandwiched in the frame body 6. , 8 are provided, and a retractable member 13 is provided on the frame body 6 via an elastic expansion / contraction member such as a coil spring 12 and a leaf spring 16 such that a part thereof protrudes from the treads 7, 8 by a predetermined amount L1. Since the sliding member 13 and the treads 7 and 8 are covered with the flexible sheet 15, the sliding member 13 retracts and is housed in the frame 6 when a pedestrian passes, and Since the sliding member 13 elastically protrudes and returns to its original state immediately after the passage, it is possible not only to prevent the pedestrians such as the elderly from falling but also to improve productivity, durability, and maintenance. It is possible to provide the door slide 1 having excellent properties.
【００２０】また、上記沓摺部材１３として断面形状が
