  Although illustration is omitted, in the present embodiment, a handrail is attached to the open end (the other end) opposite to the indoor wall surface 1 in the staircase.

  Here, in the present embodiment, the dimension in the front-rear direction of the facing portion 27 corresponds to the facing dimension L2 (see FIG. 3). As described above, the facing dimension L2 varies depending on the installation conditions such as the installation space and shape of the stairs.

  On the other hand, the baseboard provided along the corner between the indoor wall surface 1 and the step board 2 and the kick board 3 includes a horizontal baseboard 4 and a vertical baseboard 5.

  In this specification, the side of the horizontal baseboard 4 and the vertical baseboard 5 that faces (contacts) the indoor wall surface 1 is the wall surface side or the back surface side, and the opposite side is the non-wall surface side or the surface side.

  As shown in FIGS. 1 to 5, the horizontal skirting board 4 is arranged in a lateral entry corner from the rear end of the step board 2 to the vicinity of the nose 26 along the upper surface of the step board 2 among the entrance corners. Yes.

  The vertical baseboard 5 is disposed in the vertical corner of the corner from the periphery of the nose 26 to the lower end of the kicker 3 along the front surface of the kicker 3.

  The front end and the rear end of the horizontal skirting board 4 are cut off at an angle of 45 ° with respect to the length direction of the horizontal skirting board 4 and assembled in a staircase so that the front end cut 41 is inclined downward. The rear end cut opening 42 is disposed obliquely upward while being disposed.

  A horizontal baseboard-side connector attachment groove 43 that is continuous in the length direction of the horizontal baseboard 4 is formed in an intermediate portion in the width direction on the wall surface side (back side) of the horizontal baseboard 4. The front end of the mounting groove 43 is opened forward at the front end cut 41 and the rear end is opened rearward at the rear end cut 42.

  As shown in FIGS. 4 to 10, the vertical baseboard 5 includes a vertical baseboard front part 5 a and a vertical baseboard rear part 5 b that is independent of the front part 5 a.

  The vertical baseboard rear part 5b has a substantially strip-like shape. This vertical baseboard rear part 5b is configured such that the non-wall surface (front surface) is configured as a makeup surface with makeup applied, and the wall surface surface (back surface) is configured as a non-makeup surface without makeup. Has been.

  The height dimension of the vertical baseboard rear part 5b corresponds to the vertical dimension between the upper and lower adjacent step plates 2 and 2, that is, the length from the upper surface of the lower step plate 2 to the lower surface of the upper step plate 2. Is formed.

  In addition, in this embodiment, the height of the vertical baseboard rear part 5b arrange | positioned at the lowest end position, ie, the vertical baseboard rear part 5b arrange | positioned between the floor F of the downstairs, and the 1st step | paragraph board 2. The dimension is formed corresponding to the length from the surface of the floor F to the lower surface of the first step plate.

  As shown in FIGS. 6, 12, etc., the rear end of the vertical baseboard rear part 5b is linear at an angle of 45 ° so that the corner portion on the non-wall surface side is located behind the corner portion on the wall surface side. By being cut, a corner lacking portion (rear corner lacking portion) 55b is formed. As will be described later, the corner lacking portion 55b is obtained by arranging the kick plate 3 in the corner lacking portion 55b when the vertical baseboard 5 of the present invention is applied to a staircase to obtain a good fit. belongs to.

  The vertical baseboard rear part 5b has the entire front surface and the entire back surface disposed in parallel, and the front surface is disposed perpendicular to both the front and back surfaces. Accordingly, the vertical baseboard rear part 5b has a trapezoidal horizontal cross-sectional shape and is formed in a quadrangular shape.

  As shown in FIGS. 4 to 10, the vertical baseboard front part 5 a has a substantially strip-like shape. The vertical baseboard front part 5a is configured such that the non-wall surface (front surface) is configured as a makeup surface with makeup, and the wall surface (back surface) is configured as a non-makeup surface without makeup. Has been.

  A rear projecting portion 55a that protrudes rearward is formed at the rear end portion of the vertical baseboard front part 5a by forming the rear end portion in an oblique cut shape.

  The surface (surface) on the non-wall surface side in the rear projecting portion 55a is continuous with the surface of the vertical baseboard front part 5a and is disposed in the same plane. Further, in the rear projecting portion 55a, the wall-side surface (back surface) corresponding to the oblique cut surface is a flat inclined surface that is gradually positioned on the non-wall surface side toward the rear, specifically, as shown in FIG. Furthermore, it is formed in the flat inclined surface whose horizontal angle (alpha) with respect to the surface of the vertical baseboard front part 5a is 45 degrees.

  Further, the upper end and the lower end of the vertical baseboard front part 5a are cut off at an angle of 45 ° with respect to the length direction of the vertical baseboard front part 5a and assembled to the staircase. However, the lower end cut opening 52 is disposed obliquely forward while being disposed obliquely rearward.

  The width dimension (length dimension in the front-rear direction) of the vertical baseboard front part 5a is set to be the same as the width dimension (length dimension in the vertical direction) of the horizontal baseboard 4, and the vertical baseboard front part The cuts 51 and 52 of 5a and the cuts 41 and 42 of the horizontal baseboard 4 can be fastened.

  A vertical baseboard-side connector mounting groove 53 that is continuous in the length direction of the vertical baseboard front part 5a is formed at the intermediate portion in the width direction on the wall side surface (back surface) of the vertical baseboard front part 5a. . The upper end of the mounting groove 53 is opened upward at the upper end cut end 51, and the lower end is opened downward at the lower end cut end 52.

  The groove width of the vertical skirting board side connector mounting groove 53 is formed to have the same size (length) as the groove width of the horizontal baseboard side connector mounting groove 43. Further, when the cut edges 41, 42 of the horizontal baseboard 4 are fastened to the cut edges 51, 52 of the vertical baseboard front part 5a, the connecting tool mounting groove 43 of the horizontal baseboard 4 and the vertical baseboard front part 5a The connecting tool mounting groove 53 is adapted.

  Here, in the present embodiment, the horizontal baseboard 5 and the vertical baseboard front part 5a are preferably set to have a plate thickness of 5 mm to 15 mm in a portion where the connection tool mounting grooves 43 and 53 are not formed. That is, when this plate thickness is too thin, there is a risk of cracking or chipping. On the other hand, when it is too thick, it looks bad when attached to the stairs.

  Furthermore, the width of the horizontal baseboard 4 and the vertical baseboard front part 5a is preferably set to 30 mm to 70 mm in consideration of appearance.

  Further, the plate thickness of the vertical baseboard rear part 5b is preferably set to 3 mm to 13 mm in consideration of appearance.

  In this embodiment, the vertical baseboard front part 5a is set to be thicker than the plate thickness of the vertical baseboard rear part 5b. Specifically, the plate thickness of the rear part 5b is set to 0.5 to 0.9 times, more preferably 0.6 to 0.8 times the plate thickness of the front part 5a. If the plate thickness of the front part 5a is too thin, the gap between the front and rear parts 5a and 5b is exposed and the aesthetic appearance may be impaired, as will be described later. On the other hand, if the thickness of the front part 5a is too thick, the amount of protrusion of the front part 5a toward the inside (non-wall surface side) increases, which not only impairs the beauty but also increases the amount of material used. The cost may increase.

  Moreover, in this embodiment, horizontal angle (alpha) (refer FIG. 10) with respect to the surface in the back surface of the back protrusion part 55a of the vertical baseboard front part 5a is set to 20 degrees-60 degrees, More preferably, it is 30 degrees-45 degrees. good. That is, when the horizontal angle α is too large, the rear projecting portion 55a may not be able to cover the gap between the front and rear parts 5a and 5b, as will be described later, and a good aesthetic appearance may not be obtained. . On the other hand, when the horizontal angle α is too small, the rear protrusion 55a has an elongated and sharp shape, and sufficient strength cannot be ensured, which may be easily damaged.

  The baseboards 4 and 5 of the present embodiment are made of wood, but may be made of other materials such as synthetic resin. When the baseboards 4 and 5 are formed of a synthetic resin, the back surface of the rear overhang 55a, the corner lacking portion 55b, and the cut edges 41, 42, 51, and 52 do not necessarily need to be configured by surfaces that are actually cut. Alternatively, it may be configured by a molding surface molded by mold molding or the like.

  Moreover, as a makeup | decoration method in the makeup | decoration surface of the baseboards 4 and 5, methods, such as sticking a veneer and a resin sheet, or coloring when the baseboards 4 and 5 are solid materials, are used suitably.

  Needless to say, makeup may also be applied to the surface that is not exposed when the baseboards 4 and 5 are attached to the stairs.

  Moreover, it is preferable to set the depth of the connecting tool mounting grooves 43 and 53 of the horizontal baseboard 4 and the vertical baseboard front part 5a to 2 mm to 5 mm. That is, if this depth is too deep, there is a risk of cracking. On the other hand, when the depth is too shallow, the connection tool 6 described later cannot be reliably accommodated, and there is a possibility that the construction of the horizontal baseboard 4 and the vertical baseboard front part 5a may be difficult. Furthermore, the width of the connection tool mounting grooves 43 and 53 is preferably set to 10 mm to 50 mm. If the width is too narrow or too thick, it may be difficult to attach the connector 6 with high accuracy. In any case, the depth and width of the connection tool mounting grooves 43 and 53 are preferably set according to the thickness and width of the connection tool 6.

  As shown in FIGS. 3 to 5, in the present embodiment, the joining base 6 and the longitudinal baseboard front part 5 a are connected and fixed by a connecting tool 6.

  The connection tool 6 is constituted by, for example, an integrally molded product of hard synthetic resin. In addition, the connection tool 6 is attached along the indoor wall surface 1 as will be described later. In the present specification, the surface on the wall surface side is the back surface, and the non-wall surface is the same as the baseboards 4 and 5 described above. The side surface is the surface.

  As shown in FIGS. 13 to 15, the connector 6 has an L-shape when viewed from the front surface side (see FIG. 13A), and two fittings arranged at right angles to each other. Portions 61 and 61 are provided. Both fitting parts 61 and 61 in this connection tool 6 have a line-symmetrical shape (reflection object shape) with a virtual straight line A as an axis of symmetry, and have substantially the same shape (configuration).

  In the present embodiment, one of the two fitting portions 61, 61 constitutes one side and the other constitutes the other side.

  The width sizes of the fitting portions 61 and 61 of the connection tool 6 are formed to be approximately the same as the groove widths of the connection tool mounting grooves 43 and 53 of the horizontal baseboard 4 and the vertical baseboard front part 5a.

  On the surface side of the connection tool 6, a region excluding both side edges of each fitting portion 61, 61 is formed as a recess, and a counterbore recess 63 is formed.

  Further, a protruding strip-like retaining piece 64 is formed on both end surfaces of the fitting portions 61, 61 in the connection tool 6. The retaining pieces 64 are continuously formed along both side edges and are formed in a plurality in a parallel arrangement.

  In addition, although the connection tool 6 of this embodiment is a product made from a synthetic resin, you may comprise by other materials, such as a metal and a wooden material.

  Moreover, it is preferable to set the thickness of the connection tool 6 to 2 mm-5 mm in the part in which the spot facing recessed part 63 is not formed. If this thickness is too thin, it may break. If it is too thick, it is necessary to increase the depth of the connecting tool mounting grooves 43 and 53 of the horizontal baseboard 4 and the vertical baseboard front part 5a, and the horizontal baseboard 4 and the vertical baseboard front part 5a are cracked. There is a risk that.

  The width of each fitting portion 61, 61 of the connection tool 6 is preferably set to 15 mm to 50 mm. When this width is too narrow, there is a case where the fixing between the horizontal baseboard 4 and the vertical baseboard front part 5a cannot be sufficiently performed. On the other hand, if it is too thick, it may be difficult to perform the mounting operation on the horizontal baseboard 4 and the vertical baseboard front part 5a.

  The outer length B of each fitting portion 61, 61 of the connection tool 6 is preferably set to 50 mm to 100 mm. That is, when this length is too short, there is a case where the fixing between the horizontal baseboard 4 and the vertical baseboard front part 5a cannot be sufficiently performed. On the other hand, when the length is too long, the fitting operation to the horizontal baseboard 4 and the vertical baseboard front part 5a may be difficult.

  The depth of the spot facing recess 63 of the connection tool 6 is preferably set to 1 mm to 3 mm. When this depth is too shallow, when the tapping screw 65 is screwed into the counterbore recess 63 as will be described later, the screw head protrudes from the surface of the connection tool 6, and the connection tool 6 is connected to the baseboard. There is a possibility that it cannot be attached to 4,5. On the contrary, when the recessed part 63 is too deep, there exists a possibility that the connection tool 6 may be cracked.

  Needless to say, in the present embodiment, the thickness, width, length, recess depth, and the like of the connection tool 6 are appropriately changed according to the size of the baseboard 4 and the vertical baseboard front part 5a to be used. good.

  In FIGS. 14 and 15, in the portion where the parenthesized code and the parenthesized code are written side by side, the parenthesized code indicates the periphery of the connection portion with the connection tool 6 in the front part 5 a of the vertical baseboard 5. The reference numerals in parentheses indicate cross-sectional views around the connection portion of the horizontal baseboard 4 with the connection tool 6.

 In the present embodiment, when the baseboards 4 and 5 are attached to the corners between the indoor wall surface 1 and the staircase body using the connector 6, the baseboards 4 and 5 are connected to the staircase as shown below. It is customary to attach them sequentially from the upper side to the lower side.

  In the following description, the case where the horizontal baseboard 4 is first attached to the uppermost position of the horizontal baseboard 4 and the vertical baseboard 5 will be described as an example.

  First, the connection tool 6 is fixed to the horizontal baseboard 4 in advance before fixing the horizontal baseboard 4 to the indoor wall surface 1 at the corresponding corner.

  That is, the fitting portion 61 on one side of the connecting tool 6 is fitted and fixed to the front end portion of the connecting tool mounting groove 43 of the horizontal skirting board 4, and the fitting portion 61 on the other side is fixed to the front end cut end of the horizontal skirting board 4. It arrange | positions so that it may protrude below from 41 (refer FIG. 2). At this time, it arrange | positions so that the surface side (side where the spot facing recessed part 63 is formed) of the connection tool 6 may be pressed on the bottom face of the connection tool attachment groove | channel 43 in the back surface side of the horizontal baseboard 4. FIG.

  In this state, the back surface of the connection tool 6 is arranged in the same plane or slightly inside (front surface side) with respect to the back surface of the horizontal baseboard 4.

  Furthermore, in this state, the retaining pieces 64 on both side end surfaces of the fitting portion 61 on one side of the connection tool 6 engage so as to bite into the inner surfaces of both side walls of the connection tool mounting groove 43 of the horizontal baseboard 4, thereby It is fixed to the horizontal baseboard 4 with a predetermined strength without being easily removed. If necessary, the connecting tool 6 may be fixed to the horizontal skirting board 4 by using a sticking means such as an adhesive or a double-sided tape.

  Here, in the present embodiment, when the two members are connected and fixed, a member that is interposed and bonded between the bonding surfaces, such as an adhesive, a double-sided tape, and an adhesive, is referred to as a sticking means.

  In this way, the horizontal skirting board 4 having the connection tool 6 fixed to the front end is attached to the indoor wall surface 1, and the horizontal skirting board 4 is attached along the horizontal insertion corner between the uppermost step board 2 and the indoor wall surface 1. .

  The method of fixing the horizontal base 4b to the wall surface 1 is not particularly limited. For example, a method of using a fixing tool such as a nail (such as a finish nail) or a screw alone, an adhesive, a double-sided tape, etc. A method using a sticking means, a paste nail combined method using these in combination, or the like can be suitably employed.

  In this state, as described above, the fitting portion 61 on the other side of the connection tool 6 protrudes downward from the front end cut 41 of the horizontal baseboard 4 and is disposed along the indoor wall surface 1.

In this way, the vertical baseboard front part 5a is attached from the periphery of the nose 26 of the upper stepboard 2 to the upper surface of the lower stepboard 2 on the front side of the vertical baseboard rear part 5b.

  In addition, this vertical baseboard front part 5a fixes the method similar to the said horizontal baseboard 4 to the indoor wall surface 1 as needed.

  Further, as shown in FIGS. 2 and 3, a tapping screw 65 is passed through the bottom wall of the counterbore 63 in the fitting portion 61 protruding forward, and is screwed into the indoor wall surface 1. Thereby, the connection tool 6 is fixed to the indoor wall surface 1.

  Thus, in the state where the vertical baseboard front part 5a is attached and fixed to the indoor wall surface 1, as described above, the fitting portion 61 on the other side of the connection tool 6 is connected to the lower end cut end 52 of the vertical baseboard front part 5a. It protrudes forward and is disposed along the indoor wall surface 1.

  Moreover, in this state, the surface of the vertical baseboard front part 5a is arranged on the non-wall surface side (inside) with respect to the surface of the vertical baseboard rear part 5b. Accordingly, the rear projecting portion 55a of the vertical baseboard front part 5a is disposed so as to overhang the front inner side (non-wall surface side) with respect to the front end edge of the vertical baseboard rear part 5b.

  In the present embodiment, a gap is formed between the vertical baseboard front part 5a and the vertical baseboard rear part 5b. In this embodiment, the size of the gap (the dimension in the front-rear direction) is appropriately changed according to the turning dimension L2 (see FIGS. 3 and 6), so that the vertical baseboard 5 is positioned with respect to all types of stairs. Can be attached with high accuracy.

  In addition, the gap formed between the vertical baseboard front part 5a and the rear part 5b is covered with the overhanging portion 55a of the front part 5a, so that the inside of the front is covered. That is, when viewed from the front side of the stairs, the gap between the front and rear parts 5a and 5b is not seen.

  In the present invention, in some cases, a gap is not formed between the front part 5a of the vertical baseboard and the rear part 5b, and the front end of the rear part 5a is abutted against the back surface side of the protruding portion 55a of the front part 5a. You may make it contact. However, in the present invention, in most cases, a gap is formed between the front and rear parts 5a and 5b.

  As described above, in this embodiment, the vertical baseboard front part 5a may be attached before the vertical baseboard rear part 5b. In this case, after attaching the vertical baseboard front part 5a in the same manner as described above, the vertical baseboard rear part 5b is accommodated in the gap between the front part 5a and the kick plate 3 and then attached in the same manner as described above. You can do that.

  Thereafter, the fitting portion 61 on one side of the connecting tool 6 is fitted and fixed in advance to the front end portion of the connecting tool mounting groove 43 of the horizontal baseboard 4 to be constructed next in the same manner as described above. The fitting portion 61 is arranged so as to protrude downward from the front end cut end 41 of the horizontal baseboard 4.

  In this way, the horizontal skirting board 4 having the connecting tool 6 fixed to the front end is attached to the front of the lower end of the installed vertical baseboard front part 5a. At this time, the fitting part 61 of the connecting tool 6 arranged in a protruding manner at the lower end of the vertical baseboard front part 5a is inserted into the connecting tool mounting groove 43 of the horizontal baseboard 4 from the rear end cut end 42. Then, the fitting portion 61 is fitted to the rear end portion of the horizontal baseboard side connector mounting groove 43, and the rear end cut end 42 of the horizontal baseboard 4 is brought into contact with the lower end cut end 52 of the vertical baseboard front part 5a without a gap. Let Thereby, the horizontal baseboard 4 is attached along the horizontal entry corner between the step board 2 and the indoor wall surface 1 along the upper surface of the corresponding step board 2.

  In addition, in this skirting board 4, it fixes to the indoor wall surface 1 as needed similarly to the above.

  In the same manner, the vertical baseboards 5 and the horizontal baseboards 4 are alternately attached in order from the top, and the baseboards 4 and 5 are arranged over the entire corner between the surface of the staircase body and the indoor wall surface 1. Thereby, the installation work of the baseboards 4 and 5 is completed.

  In the present invention, the procedure for attaching the baseboards 4 and 5 is not limited to the above procedure, and any procedure may be used. For example, the baseboards 4 and 5 may be attached sequentially from the bottom to the top, or the baseboards 4 and 5 are appropriately attached from the middle position in the vertical direction upward or downward. May be.

  Furthermore, in the said embodiment, although the case where the horizontal baseboard 4 was constructed first was described as an example, it goes without saying that the vertical baseboard 5 may be constructed first depending on the situation of the construction site. is there.

  Moreover, in the said embodiment, before fixing the horizontal baseboard 4 and the vertical baseboard front part 5a to the wall surface 1, it is made to attach the connection tool 6 previously, but the installation operation | work of this connection tool 6 is stair construction. It may be performed on-site, or may be performed in advance at a factory or the like before being carried on-site. Furthermore, after fixing the horizontal baseboard 4 and the vertical baseboard front part 5a to which the connection tool 6 is not attached to the wall surface 1, one side fitting of the connection tool 6 from the cut end of the horizontal baseboard 4 and the vertical baseboard front part 5a You may make it attach the connecting tool 6 with respect to the horizontal baseboard 4 and the vertical baseboard front part 5a by insertion by inserting the joint part 61 later.

  As described above, according to the staircase of the present embodiment, the vertical skirting board 5 is attached in a state in which the vertical baseboard 5 is fitted with no gap along the staircase entrance corner regardless of the projecting dimension (look-back dimension L2) of the nose part 26. Can do. In other words, in the present embodiment, the vertical baseboard 5 is constituted by the two front and rear parts 5a and 5b. Therefore, by appropriately adjusting the distance between the front and rear parts 5a and 5b according to the facing dimension L2, Both parts 5a, 5b can be precisely matched along the vertical corner. Therefore, in the field, there is no need to perform troublesome cutting, measuring processing, etc. for adapting to the nose, and it can be reliably assembled only by performing simple cutting processing such as the length adjustment of the baseboards 4, 5. The baseboard assembly work can be performed efficiently and smoothly.

  Furthermore, since the front part 5a and the rear part 5b of the vertical baseboard 5 can be accurately matched along the vertical insertion corner, a good aesthetic appearance can be obtained.

  In the present embodiment, the front part 5a is made thicker than the rear part 5b over the entire area of the front and rear parts 5a, 5b of the vertical baseboard 5, and the non-wall surface at the rear end of the front part 5a. Since the rear overhanging portion 55a is formed so as to protrude rearward (inner side), the overhanging portion 55a is arranged so as to cover the front inner side of the gap between the front and rear parts 5a and 5b. Is done. For this reason, when viewed from the front side of the stairs, it is possible to prevent a problem that the gap between the front and rear parts 5a and 5b is exposed, and a good aesthetic appearance can be reliably obtained.

  Further, in the present embodiment, the vertical baseboard front part 5a and the rear part 5b are obtained by cutting the strip-like wood on both sides in the width direction with planes, and the shapes thereof are very simple. It can be manufactured easily and the cost can be reduced.

  Moreover, in the present embodiment, the strength of the vertical baseboard 5 can be sufficiently secured, and the vertical baseboard 5 is easily damaged when it is hit against other members or accidentally dropped. Can be prevented. That is, in Patent Documents 1 and 2, it is necessary to form an elongated projecting piece projecting rearward on the vertical baseboard front part or the like, and the elongated projecting piece may be easily damaged. On the other hand, the vertical baseboard of the present embodiment is not formed with an elongated projecting piece having a low strength, so that the strength can be sufficiently ensured and can be prevented from being inadvertently damaged.

  Further, since the two parts 5a and 5b constituting the vertical baseboard 5 of the present embodiment are arranged apart from each other, the front part is slid relative to the rear part as shown in Patent Documents 1 and 2 above. It is not necessary to provide a support mechanism (slide surface) or the like for supporting both the front and rear parts 5a and 5b, and accordingly, the structure can be further simplified. Can be manufactured at a low price.

  Moreover, in the vertical baseboard 5 of this embodiment, since either the front part 5a or the rear part 5b may be attached first, the assembling procedure of both the front and rear parts 5a and 5b is not restricted and can be easily assembled. Can do.

  Further, according to the stairs of the present embodiment, the corresponding end portions of the horizontal baseboard 4 and the vertical baseboard front part 5a, for example, the front end part of the horizontal baseboard 4 and the upper end part of the vertical baseboard front part 5a are provided. Since it is firmly connected via the connection tool 6, the processing accuracy of the cut edges 41, 42, 51, 52 of the horizontal baseboard 4 and the front baseboard front part 5, the baseboards 4, 5, the step board 2, the kicking-in Even if the mounting accuracy of the plate 3 is somewhat poor within an allowable range, the entire cut ends 41 and 42 of the horizontal baseboard 4 are not spaced over the entire cut ends 51 and 52 of the corresponding vertical baseboard front part 5a. Bonding (fastening) can be achieved, and a good aesthetic appearance can be reliably obtained.

  Furthermore, in this embodiment, since the retaining pieces 64 are formed on both side end surfaces of the fitting portions 61, 61 of the connector 6, the fitting portions 61, 61 are connected to the horizontal baseboard 4 and the vertical baseboard front parts. When the fitting piece 43 is inserted into the connector fitting groove 43, 53, the retaining piece 64 is engaged with the side wall of the connector fitting groove 43, 53, so that the connector fitting groove 43, 53 of the connector 6 is engaged. Can be prevented. That is, the connection tool 6 can be fixed to the horizontal baseboard 4 and the vertical baseboard front part 5 simply by fitting the connection tool 6 into the connection tool mounting grooves 43 and 53. Thus, the attachment work of the connection tool 6 can be easily performed, and the attachment work of the baseboards 4 and 5 and the staircase construction work can be easily performed.

  Moreover, in this embodiment, since the tapping screw 65 is screwed into the other side fitting part 61 of the connection tool 6 and fixed to the wall surface 1, the connection tool 6 can be firmly fixed in a stable state.

  Furthermore, in this embodiment, the counterbore 63 is formed on the surface side of the connector 6 and the tapping screw 65 is screwed into the recess 63, so that the head of the screw 65 is accommodated in the counterbore 63. Is done. For this reason, the screw head interferes with the horizontal baseboard 4 and the vertical baseboard front part 5a when the ends of the horizontal baseboard 4 and the vertical baseboard front part 5a are fitted into the screw stoppers of the connector 6. It is possible to reliably prevent problems such as

  Moreover, in this embodiment, since the connection tool 6 is previously attached to the one end part of the horizontal baseboard 4 and the vertical baseboard front part 5a, these part members 4 and 5a are stuck on the indoor wall surface 1. The connecting tool 6 can be attached to the free horizontal baseboard 4 and the vertical baseboard front part 5a that are not attached to the wall 1. For this reason, the connection tool 6 can be attached to the horizontal baseboard 4 and the vertical baseboard front part 5a almost without restriction, and the connection tool 6 can be easily attached.

  Furthermore, in this embodiment, while constructing many baseboards 4 and 5 in order from the top downward, the other side fitting part 61 of the connector 6 fitted to the constructed upper (one) baseboard is provided. Since the lower baseboard is fixed to the corresponding end of the lower (other) baseboard while being fixed to the wall surface 1 at the corresponding corner, the other side fitting of the connector 6 The operation | work which inserts a part in the corresponding edge part of a lower side baseboard can be performed easily.

  That is, if the baseboards 4 and 5 are constructed upward in order from the bottom, for example, when the lower baseboard is the vertical baseboard front part 5a and the upper baseboard is the horizontal baseboard 4, the installed vertical base The other side fitting part 61 of the connector 6 fixed to the upper end part of the wood front part 5a is arranged so as to protrude rearward. The front end of the tree 4 is fitted. In that case, the rear end portion of the horizontal skirting board 4 interferes with the kick board 3 or the like, so that it becomes difficult to fit the horizontal skirting board 4 into the connection tool 6 fixed to the vertical baseboard front part 5a. There is a fear.

  On the other hand, in this embodiment, since the baseboards 4 and 5 are constructed in order from the top, for example, when the horizontal baseboard 4 is attached to the lower end portion of the upper vertical baseboard front part 5a, the upper vertical baseboard is installed. The other side fitting part 61 of the connector 6 fixed to the lower end part of the baseboard front part 5a is arranged so as to protrude forward, and the other side fitting part 61 of the front protruding side is laterally extended from the front side. The rear end portion of the baseboard 4 is fitted. In this case, there is no part that interferes with the horizontal skirting board 4, and the work of fitting the horizontal skirting board 4 into the connecting tool 6 fixed to the vertical baseboard front part 5 can be easily performed.

  By the way, since the vertical baseboard 5 of this embodiment forms the corner lacking part 55b between the back surface (surface on the wall surface side) and the rear end surface of the component 5b thereafter, as described in detail below, It can be applied to surrounding stairs without any problems.

  For example, as shown in FIG. 16, the horizontal angle θ <b> 1 of the surface of the kick plate 3 (the front end surface of the step plate 2) with respect to the indoor wall surface 1 may be an acute angle in the surrounding staircase. In such obtuse vertical longitudinal corners, the rear end of the corner lacking portion 55b of the vertical baseboard rear part 5b abuts against the surface of the kick board 3.

  Here, when the corner lacking portion 55b is not formed in the vertical baseboard rear part 5b and the rear end surface of the rear part 5b is formed on a flat surface perpendicular to the surface, the back surface of the vertical baseboard rear part 5b ( In this case, the corner portion between the surface and the rear end surface of the vertical baseboard rear part 5b, and the kick plate. There is a risk that the gap between the surface of the surface 3 and the surface of the surface 3 becomes large and the aesthetic appearance is impaired.

  On the other hand, when the corner lacking portion 55b is formed inside the rear end of the vertical baseboard rear part 5b as in the present embodiment, the surface of the kick plate 3 is arranged in the lacking portion 55b. The gap between the surface of the vertical baseboard rear part 5b and the corner between the rear end face and the surface of the kick plate 3 can be reduced, and a good aesthetic appearance can be obtained.

  In addition, in the surrounding staircase shown in FIG. 16, the front-end edge in the back overhang | projection part 55a of the vertical baseboard front part 5a will contact | abut with the front end surface of the step board 3. FIG.

  In addition, as shown in FIG. 17, the horizontal angle θ <b> 2 of the surface of the kick plate 3 (the front end surface of the step plate 2) with respect to the indoor wall surface 1 may be an obtuse angle in the surrounding stairs. At such an acute corner, the surface of the vertical baseboard rear part 5b (the surface on the non-wall surface side) and the corner between the rear end surfaces abut against the surface of the kick plate 3. Accordingly, a gap is not formed between the vertical baseboard rear part 5b and the surface of the kick board 3, and a good aesthetic appearance can be obtained.

  Note that the front end edge of the protruding portion 55a of the vertical baseboard front part 5a comes into contact with the front end surface of the step board 2.

  As described above, even when the baseboards 4 and 5 of the present embodiment are applied to the surrounding staircase, it is possible to reliably obtain a good aesthetic without forming an inadvertent gap in the corner. .

  Needless to say, the skirting board of the present invention can be applied to a folding type staircase and a bent type staircase.

  In the above embodiment, the corner lacking portion 55b is formed at the rear end of the rear part 5a in the vertical baseboard 5, but in the present invention, the corner lacking portion is not necessarily formed.

  For example, as shown in FIG. 18, the rear end surface of the vertical baseboard rear part 5a may be formed on a surface perpendicular to the front and back side surfaces. In this case, the shape of the vertical baseboard rear part 5a can be formed more simply and can be manufactured more easily.

  Furthermore, in the present embodiment, as shown in FIG. 19, a front corner lacking portion 56b that lacks a corner portion between the front end face and the surface is formed at the front end of the vertical baseboard rear part 5b. good.

  Further, in the above embodiment, the cut edges 41, 42, 51, 52 at both ends of the horizontal baseboard 4 and the vertical baseboard front part 5a are 45 ° with respect to the length direction of the baseboard 4 and the vertical baseboard front part 5a. However, it is not always necessary to set the inclination angle of the cut surface to 45 °. For example, if the width sizes of the horizontal baseboard 4 and the vertical baseboard front part 5a are different, the inclination angle of each cut end is set to other than 45 ° according to the width size, and the horizontal baseboard 4 Further, the lengths of the corresponding cut edges of the vertical baseboard 5a may be adjusted to be equal.

  Furthermore, in the above-described embodiment, the connector fitting grooves 43 and 53 formed in the horizontal baseboard 4 and the vertical baseboard front part 5a are formed over the entire length direction of each member 4 and 5a. In the invention, the connector mounting groove may be formed only at least at the ends of the members 4 and 5a.

  Moreover, in the said embodiment, although the baseboards 4 and 5 are fixed to the wall surface 1 by sticking means, such as an adhesive agent and a double-sided tape, it is not restricted only to it, In this invention, a baseboard is screw | thread or You may make it fix to the wall surface 1 by fixing means, such as a nail.

  Furthermore, in the said embodiment, although the connection tool 6 is fixed to an indoor wall surface with the tapping screw 65, it is not restricted to it, In this invention, a connection tool is fixed to a wall surface by fixing means other than a screw. You may do it. For example, it may be fixed by using a fixing means such as a nail, an adhesive, or a double-sided tape.

  Further, when the baseboards 4 and 5 are securely fixed to the wall surface 1, it is not always necessary to fix the connection tool 6 to the wall surface 1. On the contrary, when the connection tool 6 is securely fixed to the wall surface 1, it is not always necessary to fix the baseboards 4 and 5 to the wall surface 1.

  In the above embodiment, the counterbore 63 is formed in a wide area on the surface side of the connection tool 6, but the present invention is not limited to this, and only a part of the connection tool 6, i.e., the screw stopper is seated. A hollow recess may be formed.
