Description

  The present invention relates to a stair skirting board that is provided at the wall of a staircase having a step board and a kick board and covers a corner portion between the staircase and a side wall, and a staircase structure using the same.

  As a conventional stair skirting board, a structure having a structure in which substantially L-shaped baseboard members 60... Are continuously provided along the wall of the staircase 1 as shown in FIGS. The skirting member 60 includes a horizontal piece portion 61 disposed along the upper surface of the side end portion of the step plate 2 of the staircase 1, and a vertical piece portion 62 disposed along the front surface of the side end portion of the kick plate 3. Is integrated. The rear end portion of the horizontal piece portion 61 and the lower end portion of the vertical piece portion 62 are cut obliquely, and the nose 4 of the step plate 2 is fitted into the connecting portion between the horizontal piece portion 61 and the vertical piece portion 62. A cut-out groove 63 is formed. Then, the stair skirting board is in a state where the lower end portion of the vertical piece portion 62 in the upper skirting board member 60 and the rear end portion of the horizontal piece portion 61 in the lower skirting board member 60 are joined and joined. It is constructed so as to obscure the corner between the wall 5 and the side wall 5.

  The staircase 1 often has variations in construction accuracy due to dimensional errors, assembly errors, and the like of the step plate 2 and the kick plate 3. Therefore, in the field construction of the stair skirting board, depending on the construction state of the stairs 1, the stair contact surface (the part indicated by the dotted line in FIG. 5) of the horizontal piece part 61 and the vertical piece part 62 in each skirting board member 60 is used. Cut and adjust the diagonally cut joint surface (portion shown by the one-dot chain line in FIG. 5) to bring each base plate member 60 into contact with the stairs 1 without any gaps, and the base plate members 60, Even in the joint portion 64 between the 60, the appearance is improved so that no gap is generated. However, in-situ processing adjustment such as cutting adjustment and cutting adjustment of each base material member 60 has a problem that it is very complicated and time-consuming and requires skill.

  Therefore, in recent years, as shown in FIG. 7, by using two members, a horizontal skirting member 71 for the step board and a vertical skirting member 72 for the kick plate, these horizontal skirting members 71. In addition, a stair skirting board has been proposed in which the vertical skirting members 72... Are alternately continued along the wall of the staircase 1 (see, for example, Patent Document 1). The horizontal skirting board member 71 is disposed along the upper surface of the side end portion of the corrugated board 2, and the vertical skirting board member 72 includes a lower surface of the front end part of the upper horizontal skirting board member 71 and a rear end part of the lower horizontal boarding member 71 It is arranged along the front surface of the side end portion of the kick plate 3 so as to straddle between the upper surface. Further, a notch step portion 73 for fitting the nose 4 of the step plate 2 is formed at the upper end portion of the vertical width member 72.

  Thus, by setting the stair skirting board as a two-member configuration, the horizontal skirting board member 71 and the vertical skirting board member 72 can be separately arranged on the step board 2 and the kick board 3, respectively. Even if the construction accuracy of 1 is deteriorated (for example, even if the step board 2 and the kick board 3 are not exactly orthogonal), between the horizontal board member 71 and the step board 2, the vertical board member 72 and It is possible to make it difficult for a gap to be formed between the kick plate 3. In addition, when the construction accuracy of the staircase 1 is deteriorated, a gap is generated in the joint portions 74 and 75 of the horizontal skirt member 71 and the vertical skirt member 72, but by adopting a two-member configuration, As disclosed in Patent Document 1, for example, the width of the horizontal board member 71 is made thicker than that of the vertical board member 72, or the front end portion of the horizontal board member 71 is projected forward of the vertical board member 72. It is possible to take measures to make the gaps inconspicuous. Thereby, it is possible to maintain the appearance to some extent while omitting the processing adjustment at the site that is complicated and requires skill.

  However, in the stair skirting board having the structure as shown in FIG. 7, the joint portion 74 between the lower surface of the front end portion of the horizontal skirting member 71 and the upper end surface of the vertical skirting member 72 extends forward from the nose 4 of the stepboard 2. Further, the joint portion 75 between the upper surface of the rear end portion of the horizontal skirt member 71 and the lower end surface of the vertical skirt member 72 is positioned so as to project forward from the nose 4 of the step board 2. is doing. That is, these joint portions 74 and 75 are disposed at positions that are easily visible to the user going up and down the stairs 1. For this reason, even if the above measures are taken, there is a limit to making the gaps generated in the joint portions 74 and 75 inconspicuous, and there is room for further improvement in improving the appearance.

  Further, when the step board 2 and the kick board 3 vibrate when going up and down the stairs 1, the step board 2 and the kick board 3 and the stair skirting board may rub against each other. No measures were taken for measures to prevent sounding.

  Therefore, the present invention solves the above-mentioned problems, makes it possible to improve the appearance while eliminating the need for on-site processing adjustment and making the construction easy, and prevents sounding when going up and down the stairs. An object is to provide a stair skirting board that can be used and a staircase structure using the same.

  The stair skirting board 10 of the present invention is provided on the wall of the staircase 1 including the step board 2 and the kick board 3 and is provided with a horizontal board member 20 for the step board and a kick board. The horizontal skirting member 20 is composed of two members, ie, vertical skirting members 40..., And the horizontal skirting member 20 is disposed along the upper surface of the side end portion of the step plate 2 and the kick plate in the step plate 2. 3 and a front end portion 22 disposed so as to surround the side end portion of the nose 4 projecting forward from the front surface of the nose 3, and the vertical width member 40 is formed at the front end portion 22 of the upper horizontal width member 20. Arranged along the front surface of the side end portion of the kick plate 3 so as to straddle between the lower piece 25 located on the lower side of the nose 4 and the rear end portion of the main body portion 21 of the lower width wooden member 20. It is characterized by being installed.

In addition, since the gap closing member is interposed as a cushion, it is possible to prevent noise due to friction between the step board and the width board member.

  Furthermore, by contacting a gap closing member having outer and inner elastic pieces with different overhang amounts to the step plate, the outer elastic piece that has been greatly deformed by tightly contacting the step plate is brought into light contact with the step plate. And can be covered by an inner elastic piece that is hardly deformed. Thereby, even though the gap between the step board and the skirting board member is closed by the elastically deformable gap closing member, the shape of the exposed portion of the gap closing member is maintained well, and the appearance is further improved. Can be good.

  In addition, by forming the vertical skirt member in, for example, a square bar shape and positioning it behind the nose front end surface of the corrugated plate, the joint portion of the horizontal skirt member and the vertical skirt member, that is, the gap generation portion is greatly increased. As a result, it is possible to make the gap generated in the joint portion inconspicuous, and it is possible to eliminate the need for jointing the joint portion. Furthermore, the gap in the joint portion can be eliminated by performing simple processing adjustments such as cutting the square bar-like vertical skirting wooden member at the site in accordance with the interval between the upper and lower horizontal skirting wooden members.
