In consideration of the person, the space between the edge 16e on the indoor side of the decorative material holding portion 16d or the upper end of the decorative material 18 and the upper surface of the lower frame soil portion 16a is 20 mm or less.

  According to the fitting 10 of the above-described embodiment, the metal portion on the abutting surface 28 a side with which the peripheral edge of the entrance door 12 abuts, that is, the lower end 34 e of the abutting surface side portion 34 a is the seal holding portion 16 c of the lower frame 15. Therefore, a region where the metal part on the contact surface 28a side of the front door 12 and the metal part of the lower frame 15 overlap in the height direction is secured. For this reason, it is possible to use the entrance door 12 as a fireproof door while providing the cushioning material 33 in the lower part of the entrance door 12. At this time, since the lower end 36a of the holding portion 36 provided on the support member 34 is higher than the lower end 34e of the contact surface side portion 34a, the cushioning material 33 is disposed on the side opposite to the contact surface 26a to thereby contact the contact surface side. It is possible to suppress the lower end of the portion 34a from being exposed and to dispose the cushioning material 33 on the side where the entrance door 12 is moved (opened side). Therefore, when the entrance door 12 is opened from the outdoor side (from the opening direction side), even if the foot of the person who operated the entrance door 12 and the lower end of the entrance door 12 are in contact with each other, the entrance door 12 Since the shock-absorbing material 33 that is elastically deformable protrudes from the lower end of the outdoor side rather than the metal anti-contact surface 26a, it is possible to suppress the injury of the foot of the operator.

  In addition, since the aluminum support member 34 covers the lower edge side of the door panel 20 having the frame 24, the outer surface material 26 and the inner surface material 28, the frame 24, the outer surface material 26 and the inner surface are formed on the lower end side of the door panel 20. The edge of the material 28 is not exposed to the outside. For this reason, it is possible to prevent the outer surface material 26 and the inner surface material 28 from being twisted, peeled off, and rusted at the lower end of the door panel 20.

  Further, by providing the support member 34 on the door panel 20, the lower end 34 e of the contact surface side portion 34 a, which is a metal portion on the contact surface 28 a side of the entrance door 12, is connected to the metal on the anti-contact surface 26 a side of the entrance door 12. It is possible to realize a fire-proof door that is lower than the lower end 36a of the anti-contact surface side portion 34b that is a part. Moreover, since the contact surface side part 34a is flush with the contact surface 28a, it is possible to ensure airtightness and watertightness between the entrance door 12 and the frame body 14 and to improve design. .

  Further, since there is a gap between the lower end of the entrance door 12 and the intersoil surface 11 and the lower frame interstitial portion 16a, the cushioning material 33 comes into contact with the interstitial surface 11 and the lower interframe soil portion 16a when the entrance door 12 is opened and closed. It is not worn or damaged, and prevents the entrance door 12 from coming into contact with the intersoil surface 11 and the lower frame interstitial part 16a, etc., even if deformation such as changes over time in construction or warping due to the environment or the like occurs. It is possible.

  In the above embodiment, the frame 24 is made of resin, but may be made of steel. In this case, the screws 51 for fixing the lower end structure 32 can be directly screwed to the frame 24 without providing the fixing member 23.

  Moreover, in the said embodiment, although the example which comprised the lower end structure 32 with the buffer material 33 and the support member 34 was demonstrated, it does not restrict to this. For example, the elastically deformable cushioning material and the support member may be configured as one component by adhesion, welding, integral molding, or the like.

  Further, although the support member 34 is made of aluminum, it may be made of resin or steel, and in the case of resin, the lower end of the metal outer surface material 26 and the inner surface material 28 are respectively metal on the anti-contact surface side. The lower end of the part may be the lower end of the metal part on the contact surface side.

  Further, although the outer surface material 26 and the inner surface material 28 are made of steel, it is not necessary to make all the parts of the outer surface material 26 and the inner surface material 28 of steel, and some of them are made of other materials. May be. For example, non-metals such as glass, resin, wood, and other metals other than steel may be used. Moreover, you may comprise the outer surface material 26 and the inner surface material 28, without using steel.

  Further, the fixing member 23 may be made of a material other than steel, or may be other metals such as stainless steel or aluminum.

  Moreover, in the said embodiment, the support member 34 made from aluminum is attached to the lower end of the door panel 20, and the lower end of the metal part by the side of the contact surface 28a becomes the lower end 34e of the contact surface side site | part 34a, and anti-contact surface 26a Although the lower end of the metal portion on the side is configured to be the lower end 36a of the holding portion 36 provided on the support member 34, the present invention is not limited to this. For example, as shown in FIG. 4A, the frame 24 is formed so as to have a step so that the contact surface 28a side is lower than the anti-contact surface 26a side, and the recess 24a on the anti-contact surface 26a side is formed. A lower end structure 38 to be accommodated may be provided. Further, as shown in FIG. 4B, a fixed plate portion 44a that is fixed on the lower surface of the frame 24 on the lower side of the frame 24, and a room-side edge of the fixed plate portion 44a are suspended downward. A metallic extension member 44 having a hanging plate 44 b may be provided, and the outer surface material 26 and the inner surface material 28 extending from the door panel 20 side may be formed so as to cover the edge of the extension member 44. In this case, the lower end structure 38 is fixed so that the outdoor side surface of the cushioning material 33 is substantially flush with the anti-contact surface 26a. In the present embodiment, an example in which the holding portion 36 that holds the cushioning material 33 has a shape opened downward and the attachment piece 33a provided on the top of the cushioning material 33 is inserted from below is described. As shown in (c), the holding portion 36 may be open to the outdoor side, and the attachment piece 33a provided on the indoor side surface of the cushioning material 33 may be inserted from the outdoor side.
