It is possible.

In the present invention, a door sealing device 1 (hereinafter simply referred to as the sealing device 1) has a bar member 2, a fiber bundle 7, an end cap 3 and an end cap 4, and a slide piece 5. . The bar member 2 is a long mold member having a constant cross-section, and is made of metal or hard plastic, for example, aluminum, and its longitudinal dimension is matched to the width of the door to be mounted. The cross-sectional shape of the bar material 2 is a horizontal upper surface 2a having a thickness T, bottom surfaces 2f 1 and 2f arranged in parallel in the horizontal direction, a pair of side walls 2b and 2b vertically opened upward between the bottom surfaces 2f and 2f, and side walls. 2b and 2b, a substantially rectangular engaging portion 2c having an inner width W and a height H, which are continuously provided, and a plurality of rows of narrow groove recesses 2d and 2d below the front and rear outer side surfaces of the side walls 2b and 2b. Thick groove recesses 2e are provided on the front and rear outer side surfaces of the side walls 2b, 2b. The bar member 2 has an opening formed by the side walls 2b, 2b and the engaging portion 2c to form a void having a substantially T-shaped cross section. The fiber bundle 7 is formed by densely implanting the bundle-like fibers on the surface of the sheet-like base cloth, and the base cloth is adhered to the surfaces of the bottom surfaces 2f and 2f with the tips of the bundle-like fibers substantially aligned. . The fiber bundle 7 is not limited in the type and thickness of the fiber, but for example, when soft fibers having a mohair tone are selected, the contact is soft and easy to seal, and synthetic fibers are used for good durability.

The end cap 3 is used on the side of the closing frame, and is arranged on the left end surface of the bar member 2 on the side that comes into contact with the frame when the door is closed in FIGS. 1 (a) and 1 (d), and FIG. 2 (a). As shown in FIGS. 4 (a) and 4 (b), a vertically long and substantially rectangular plate-like substrate 3a and a substantially rectangular upper opening 3b above the central portion of the substrate 3a are projected to the right side. A box-shaped bottom 3c having a fixing hole 3f formed in its bottom surface, a gate-shaped lower opening 3e formed below the central portion of the substrate 3a, and an arc in the middle of the openings 3b and 3e. It has an oblong adjustment hole 3d having a center-to-center distance X and a notch 3g formed on the right side of the substrate 3a so as to surround the adjustment hole 3d and cut into a substantially rectangular shape. The cut portion 3g has a width P and a height Q. The end cap 4 is used on the opposite side of the closing frame, and is disposed on the left end surface of the bar member 2 in FIGS. 1 (a) and 1 (d) and 2 (a), and is shown in FIGS. 5 (a) and 5 (b). As shown in the figure, a vertically long and substantially rectangular plate-shaped substrate 4a, a gate-shaped lower opening 4e formed below the central portion of the substrate 4a, and an arc center distance X long just above the opening 4e. It has a circular adjustment hole 4d, a fixing hole 4f formed in the center of the substrate 4a, and a notch 4g formed in a substantially rectangular shape on the right side of the substrate 4a so as to surround the adjustment hole 4d. . The cut portion 4g has a width P × height Q. As shown in FIGS. 6 (a) and 6 (b), the slide piece 5 is connected to a rectangular parallelepiped base 5a and an L-shaped cross section from the lower end of the base 5a so that the tip slightly projects from the surface of the base 5a. It also has a tongue piece 5b and a screw hole 5c bored above the center of the base 5a. The base 5a has a width p which is the same as or slightly narrower than the width P of the cut portions 3g and 4g, and the tongue piece 5b has the width W × height H which is the same as or slightly narrower than the width W × height H of the engaging portion 2c. The sum of the height q of the base 5a and the tongue piece 5b added to the center-to-center distance X is equal to or slightly smaller than the height Q of the cut portions 3g and 4g. If a small protrusion 5d is provided at the center of the lower end of the base 5a toward the tongue piece 5b, it is possible to reliably prevent rattling during assembly of the sealing device 1 described later. It is preferable that the tongue piece 5b is tapered at the outer side of the end portion so that it can be smoothly mounted. The distance t between the lower end of the small projection 5d and the upper surface of the tongue piece 5b shown in FIG. 6 (b) is the same as or slightly wider than the thickness T of the upper surface 2a. Here, when the small protrusion 5d is not provided, the lower surface of the base 5a and the upper surface of the tongue piece 5b are spaced at a distance t.

The above-mentioned end caps 3 and 4 may be arranged so as to be aligned with the end cap 3 having a box-shaped bottom portion 3c on both sides. At this time, each opening portion 3b is arranged outside and each bottom portion 3c is arranged inside. You can use it. Alternatively, the end caps 3 and 4 may be aligned with the end cap 4 that does not have the bottom portion 3c on the left and right, and at this time, the cut portions 4g may be disposed so as to face inward. Further, since the narrow groove recess 2d and the thick groove recess 2e of the bar material are provided to maintain the strength while reducing the weight, this groove is not always necessary. The guide used in the sealing device 1 is not particularly limited, and various types can be selected. As an example, the guide 6 shown in FIG. 3 includes a guide body 6b having a substantially rectangular parallelepiped shape protruding from the central portion of the substrate 6a and a guide body 6b. The body 6b has a pair of oval fixing holes 6c 1 and 6c 1 formed on the left and right sides thereof. Except for the fiber bundle 7, each member used in the present invention is made of metal, hard plastic or the like. In the case of metal, aluminum, stainless steel or the like is usually preferable.

Next, assembly, attachment and operation of the sealing device 1 will be described. The tongue piece 5b of the slide piece 5 is fitted to the left and right end edges of the engaging portion 2c of the bar member 2 to which the fiber bundles 7 are bonded in parallel with the bottom surfaces 2f and 2f in advance, and the tongue piece 5b and the small protrusion 5d are joined together. The upper surface 2a is sandwiched between them to prevent rattling, and the cutout portions 3g, 4g of the end caps 3, 4 are fitted on the left and right outer surfaces of the base 5a so that the gate shapes of the lower openings 3e, 4e are formed on the side wall 2b. 2b The adjustment holes 3d and 4d and the screw hole 5c are loosely screwed to each other with fixing members 8 and 8 such as countersunk head bolts in accordance with the gap. Next, the end caps 3 and 4 are firmly screwed into the fixing holes 3f and 4f from the left and right outside of the door 11 indicated by the chain double-dashed line with fixing tools 9 and 9 such as countersunk head bolts and wooden screws. Here, since the lower end of the door 11 is carved with portions corresponding to the bar material 2, the end caps 3 and 4, and the slide piece 5, the lower end edge of the door 11 reaches the level of the bottom surface 2f, 2f of the bar material 2. Reaching the upper surface 2a of the bar member 2 while avoiding the end caps 3 and 4 and the slide piece 5, and in appearance, only the fiber bundle 7 projects from the lower end surface of the door 11, and the lower left and right end surfaces of the door 11 Only the end caps 3 and 4 can be seen from. Further, the sealing device 1 adjusts the gap between the lower end surface of the door 11 and the floor surface by moving the tip of the fiber bundle 7 up and down according to the fluctuation in the field. The fixing tools 8 and 8 are firmly fixed at the upper limit positions in the oblong adjustment holes 3d and 4d of the end caps 3 and 4. On the other hand, FIG. 1 (b) shows the case of the lower limit position, and the fasteners 8, 8 are firmly fixed at the lower limit position in the oblong adjustment holes 3d, 4d of the end caps 3, 4. Only the center distance X between the upper limit position and the lower limit position is the adjustable range. In the case of adjusting the middle distance of the center-to-center distance X, it is possible to adjust steplessly by selecting the fixing position of the fixing tools 8, 8 in the middle. The end cap 3 has a box-shaped bottom portion 3c, and a locking projection (not shown) mounted on the closing frame side of the door can be engaged when the door is closed. In the sealing device 1, the lower ends of the fiber bundles 7 can be easily moved up and down by moving the fasteners 8, 8 within the adjustment distances 3d, 4d within the range of the maximum distance X, and the gap between the hanging door type door and the floor surface. Even if the size changes, it can be flexibly adjusted, and the fiber bundle 7 at the lower end allows the gap to be maintained in a sealed state easily and quickly.

As shown in FIGS. 1 (a) and 1 (b), the guide 6 is such that the wide surface of the guide body 6 b is normally aligned with the side walls 2 b and 2 b of the bar member 2 on the side of the closing frame, and the fixing holes 6 c, For example, 6c is passed through a fixing tool 10 such as a wood screw or a bolt to fix the substrate 6a on the floor surface. When the door is opened and closed, the lower openings 3e and 4e of the end caps 3 and 4 and the side walls 2b and 2b can be guided and moved by the guide body 6b fixed on the floor, so that the door can be prevented from wobbling. The guide here may be different from the one shown in Fig. 3 as long as it has a shape and structure that can suppress wobbling when opening and closing the door, but it should be mounted as close as possible to the closing frame side so that it does not obstruct traffic. It is preferable to select it.
