The length in the vertical direction (and the length in the left-right direction) of the downstairs parting material 42 is equal to the length in the vertical direction (and the length in the front-rear direction) of the upper floor parting material 41. The length in the left-right direction of the downstairs parting material 42 is equal to the length in the left-right direction of the contact end surface 15 a of the nose 153. The right end surface of the upper floor parting material 41 and the rear end surface of the lower floor parting material 42 form a joint rectangular shape.

  The downstairs parting material 42 is generally decorated (see FIG. 5). Similar to the upper floor parting material 41, the lower floor parting material 42 is made up by winding a single decorative sheet 422 around the main body 421 of the lower floor parting material 42 in the circumferential direction. That is, the upper side surface and the left and right side surfaces of the downstairs parting material 42 are seamlessly covered with the decorative sheet 422, but the main body 421 is partially exposed on the lower side surface. Further, a sheet-like decorative member 423 is attached to the front end face of the downstairs parting material 42.

The corner member 401 makes the upper parting material 41 and the lower parting material 42 L-shaped by bringing the right end surface of the upper parting material 41 and the rear end surface of the lower parting material 42 into contact with each other. Butted and joined (for example, bonded). That is, the corner member 401 integrally includes the upper floor parting material 41 and the lower floor parting material 42 in an L shape.
In the corner member 401, the butted portion of the upper floor parting material 41 and the lower floor parting material 42 is decorated. This is because the right end surface of the upper floor parting material 41 that is not decorated and the rear end surface of the lower floor parting material 42 are blinded by the contact between the two.

The nosing parting material 43 has a long rod shape in the vertical direction (see FIGS. 3 and 7). The cross-sectional shape of the nosing parting material 43 is rectangular. The length in the front-rear direction (and the length in the left-right direction) of the nosing parting material 43 is equal to the length in the vertical direction (and the length in the left-right direction) of the downstairs parting material 42.
The nosing parting material 43 is generally made up. The nosing parting material 43 is made up by winding a single decorative sheet around the main body of the nosing parting material 43 in the circumferential direction, like the upper parting material 41. That is, the right side surface and both front and rear side surfaces of the nosing parting material 43 are seamlessly covered with the decorative sheet, but the main body is partially exposed on the left side surface.

The upper floor covering member 44 has a rectangular plate shape extending in the vertical and horizontal directions (see FIGS. 2 and 8). The thickness (length in the front-rear direction) of the upper floor covering member 44 is equal to or less than the length in the front-rear direction of the upper floor parting material 41.
At least the rear surface of the upper floor covering member 44 is decorated with a decorative sheet.

The downstairs covering member 45 has a rectangular plate shape extending in the up-down and front-back directions (see FIGS. 2 and 8). The length in the front-rear direction of the left side surface of the downstairs covering member 45 is shorter than the right side surface. The rear end face of the downstairs covering member 45 is a convex curved surface that curves over the left and right end faces of the downstairs covering member 45. The length of the downstairs covering member 45 in the vertical direction is the same as that of the downstairs covering member 44. The thickness of the lower floor covering member 45 excluding the rear end is the same as that of the upper floor covering member 44.
At least the right surface and the rear end surface of the downstairs covering member 45 are decorated with a decorative sheet.

The covering member 402 brings the downside covering member 45 and the downstairs parting material 42 into an L shape by bringing the right end surface of the downside covering member 45 and the rearmost end portion of the left surface of the upstairs covering member 44 into contact. Matched in a letter shape.
In the covering member 402, the L-shaped outer surface of the butted portion between the upper floor parting material 41 and the lower floor parting material 42 is entirely covered.
The covering member 402 may have a configuration in which the rightmost end portion on the front surface of the upper floor parting material 41 and the rear end part of the lower floor parting material 42 are brought into contact with each other. In this case, it is necessary to make up the right end face of the upper floor parting material 41.

Next, preparation of the corner member 401 and the nosing parting material 43 and arrangement | positioning to the stairs 1 are demonstrated.
The installer obtains the corner member 401 from the L-shaped member 501 indicated by a broken line in FIG. The L-shaped member 501 has rod-shaped members 51 and 52 (bar-shaped portions). Further, the installer obtains the nosing parting material 43 from the rod-shaped member 53 indicated by a broken line in FIG.
The bar-shaped member 51 has the same configuration as the upper floor parting material 41, but the bar-shaped member 51 is longer than the upper floor parting material 41. The rod-like member 52 (and the rod-like member 53) has the same configuration as the downstairs parting material 42 (and the nose parting material 43), but the rod-like member 52 (and the rod-like member 53) is the downstairs parting material 42 (and the nose). Longer than parting material 43).

Each of the rod-shaped members 51 and 52 is easily obtained by winding a decorative sheet around a square bar and cutting off one end of the square bar at 45 °. The rod-shaped member 53 is obtained by winding a decorative sheet around a square member. It is desirable that the square member and the decorative sheet are shared between the rod-shaped members 51 to 53.
The rod-shaped members 51 to 53 can be easily mass-produced at a factory. Therefore, these can be obtained at low cost.
Like the corner member 401, the L-shaped member 501 is formed by abutting the rod-shaped members 51 and 52 into an L shape and further joining them. The L-shaped member 501 is manufactured at a factory. Therefore, it is not necessary for the builder to abut the bar members 51 and 52 at the construction site. The installer may assemble the L-shaped member 501 from the rod-shaped members 51 and 52 at the construction site.

The installer cuts (length cuts) the rod-shaped members 51 and 52 constituting the L-shaped member 501 in accordance with the dimensions of the stairs 1. Further, the installer attaches the decorative member 423 to the front end surface of the bar-shaped member 52 after cutting. As a result, the installer obtains the corner member 401 having the upper floor parting material 41 and the lower floor parting material 42.
Further, the installer obtains the nosing parting material 43 by cutting (length-cutting) the rod-shaped member 53 according to the dimensions of the stairs 1. In addition, if the rod-shaped member 51 (or rod-shaped member 52) is long enough, it is possible to use the remainder which the construction person cut | disconnected the rod-shaped member 51 (or rod-shaped member 52) as the rod-shaped member 53. FIG.

  The installer who has obtained the corner member 401 places it on the stairs 1. At this time, the installer places the corner member 401 on the upper surface of the tread plate 151 by bringing the inside of the L-shape of the corner member 401 into contact with the protruding corner 31. More specifically, the installer places the upper floor parting material 41 between the protruding corner 31 and the kick plate 162 side, and the front side surface (and the lower side surface) of the upper floor parting material 41 is the rear surface 3b (and the step board 151). The upper floor parting material 41 covers the boundary portion between the rear surface 3b and the upper surface of the tread plate 151. Further, the installer places the downstairs parting material 42 between the exit corner 31 and the nose 153, and the left side (and lower side) of the downside parting material 42 contacts the right side 3a (and the upper surface of the tread 151). The downstairs parting material 42 covers the boundary portion between the right surface 3a and the upper surface of the tread plate 151. In the present embodiment, the corner member 401 covers the boundary portion between the housing 3 and the tread surface of the tread plate 151.

  The front end portion of the downstairs parting material 42 is disposed on the upper side of the contact end surface 15a of the nose 153, and projects forward from the contact end surface 15a. That is, the front end portion of the downstairs parting material 42 is a protruding portion of the downstairs parting material 42. The protruding length of the downstairs parting material 42 from the contact end face 15 a is equal to the length of the nose parting material 43 in the front-rear direction. The decorative member 423 makes up the front end face of the downstairs parting material 42, that is, the end face in the protruding direction of the protruding portion of the downstairs parting material 42.

The contractor who has obtained the nosing parting material 43 places it on the stairs 1. At this time, the installer butts the upper end surface of the nosing parting material 43 in an L shape from the lower side to the projecting portion of the downstairs parting material 42, and contacts the contact end surface 15 a (and the right side 3 a) of the nose 153 of the nosing parting material 43. The rear side surface (and the left side surface) of the nosing parting material 43 is brought into contact. As a result, the nosing parting material 43 hangs downward from the nose 153 from the protruding part of the downstairs parting material 42 and covers the boundary between the nose 153 and the right surface 3a. At this time, the lower end surface of the nosing parting material 43 is in contact with the upper surface of the tread plate 141.
The nosing parting material 43 contacts the contact end surface 15a, but does not contact the non-contact surface 15b.

In the present embodiment, the downstairs parting material 42 and the nosing parting material 43 are arranged sideways. However, the corner structure 21 may include a downstairs parting material and a nosing parting material arranged in a vertical win. In this case, for example, a sheet-like decorative member may be attached to the upper end surface of the nosing parting material.
Moreover, even if the front end part of the downstairs parting material 42 and the upper end part of the nose parting material 43 are cut at an angle of 45 ° at the construction site, the downside parting material 42 and the nose parting material 43 are connected to 90 °. Good. In this case, since the decorative member 423 is unnecessary, the number of parts is reduced.

Next, preparation of the covering member 402 and arrangement on the staircase 1 will be described.
The installer obtains the covering member 402 from the plate-like member 502 shown in FIGS. 8 and 9 (illustrated by a broken line in FIG. 8).
The plate member 502 has a rectangular flat plate shape. One end surface in the short direction of the plate-like member 502 is curved similarly to the rear end surface of the downstairs covering member 45. The length of the long side portion of the plate-like member 502 is longer than the vertical length of the upper floor covering member 44 (or the lower floor covering member 45). The length of the short side portion of the plate-like member 502 is longer than the sum of the length in the left-right direction of the upper floor covering member 44 and the length in the front-rear direction of the lower floor covering member 45.

The plate-like member 502 is made up by winding a single decorative sheet 504 around a rectangular flat plate-like main body 503. In FIG. 9, the main body 503 and the decorative sheet 504 are illustrated so as to be separated from each other so that they can be easily understood. One surface and the other surface of the main body 503 have the same length in the longitudinal direction, but the length in the short direction is shorter on one surface (the surface on the right side in FIG. 9).
The decorative sheet 504 entirely covers one surface of the main body 503 and both end surfaces in the lateral direction. On the other surface of the main body 503, a peripheral edge portion of the decorative sheet 504 is disposed, and the main body 503 is partially exposed. Since such a plate-like member 502 can be easily mass-produced at a factory, it can be obtained at a low cost.
The main body 503 is preferably made of a material common to the square members constituting the rod-shaped members 51 to 53 (for example, wood or wood material). It is desirable that the decorative sheet 504 is shared with the decorative sheet constituting the rod-shaped members 51 to 53.

The installer first divides the plate-like member 502 into two parts. In FIG. 8, the divided plate-like members 54 and 55 obtained by dividing the plate-like member 502 into two in the short direction are indicated by broken lines. The divided plate member 54 includes the other end surface of the plate member 502 in the short direction, and the divided plate member 55 includes one end surface of the plate member 502 in the short direction.
The installer further cuts the divided plate-like member 54 according to the dimensions of the stairs 1 (length cut and width cut) to obtain the upper floor covering member 44. Further, the installer further cuts the divided plate-like member 55 according to the dimensions of the stairs 1 (length cut and width cut) to obtain the downstairs covering member 45. That is, the installer obtains two members that constitute the covering member 402.

  In the present embodiment, the installer obtains the upper floor covering member 44 and the lower floor covering member 45 from the plate-like member 502, but is not limited to this, and the upper floor covering is obtained from two different plate-like members. The member 44 and the downstairs covering member 45 may be obtained separately.

  The installer who has obtained the upper floor covering member 44 and the lower floor covering member 45 places them on the stairs 1. At this time, the contractor places the upper floor covering member 44 between the protruding corner 31 and the kick plate 152, and the upper floor covering member 44 has a boundary between the rear surface 3 b and the lower surface of the tread plate 151 and the kick plate 152. Covering the portion, butting the right end portion of the upper floor covering member 44 and the rearmost end portion of the left surface of the lower floor covering member 45, and arranging the lower floor covering member 45 between the exit corner 31 and the nosing parting material 43, A boundary portion between the right surface 3a and the lower surface of the tread plate 151 is covered. For this purpose, the installer brings the left end portion (and the front surface) of the upper floor covering member 44 into contact with the kick plate 152 (and the rear surface 3b), and the left surface (and the front end surface) of the lower floor covering member 45 as the right surface 3a ( And the rear side of the nosing parting material 43). At this time, the upper end surfaces (and the lower end surfaces) of the upper floor covering member 44 and the lower floor covering member 45 are in contact with the lower surface of the tread plate 151 (and the upper surface of the tread plate 141).

  As a result, the covering member 402 is configured using the upper floor covering member 44 and the lower floor covering member 45. That is, the installer places the covering member 402 between the nosing parting material 43 and the kick plate 152, and covers the lower surface of the tread plate 151 and the boundary portions between the kick plate 152 and the casing 3 with the covering member 402.

Each of the corner member 401 and the covering member 402 arranged on the staircase 1 is generally covered with a portion that is easily visible to the user. Therefore, it is suppressed that the beauty | look of the staircase 1 is spoiled because each of the corner member 401 and the covering member 402 is composed of two members.
The staircase 1 may be configured such that the kick plate 152 is adjacent to the right surface 3a. In this case, the covering member 402 only needs to have the downstairs covering member 45.
The order in which the upper floor parting material 41 to the lower floor covering member 45 are arranged on the stairs 1 is not limited to this order.

Next, referring to FIG. 1 and the following FIGS. 10 to 13, the horizontal parting material 46, the first vertical parting material 47, and the second vertical parting material 48 related to the step board 141 and the kick plate 142. explain.
FIG. 10 is a perspective view schematically showing a parting operation related to the tread board 131.
FIG. 11 is a perspective view schematically showing the configuration of the horizontal parting member 46.
FIG. 12 is a perspective view schematically showing the configuration of the first vertical parting material 47.
FIG. 13 is a perspective view schematically showing the configuration of the second vertical parting material 48.

The side parting material 46 is a rod-like member that is long in the front-rear direction (see FIGS. 10 and 11). The installer obtains the horizontal parting material 46 by cutting the length of the rod-shaped member 56 indicated by the broken line in FIG.
The first vertical parting material 47 is a bar-like member that is long in the vertical direction (see FIGS. 10 and 12). The installer obtains the first vertical parting material 47 by cutting the length of the rod-shaped member 57 indicated by a broken line in FIG.

Each of the rod-shaped members 56 and 57 is obtained by cutting off one end portion of a square member around which a decorative sheet is wound at 45 °. The cut-off portion of the bar-shaped member 56 becomes the front end portion of the horizontal parting material 46, and the cut-off portion of the bar-shaped member 57 becomes the upper end portion of the first vertical parting material 47.
The lateral length of each of the horizontal parting material 46 and the first vertical parting material 47 is equal to the length of the nose parting material 43 in the lateral direction. The length of the horizontal parting material 46 in the vertical direction and the length of the first vertical parting material 47 in the front-rear direction are equal to the length of the nose parting material 43 in the front-rear direction.
Each of the rod-like members 56 and 57 is mass-produced at a factory. It is desirable that the square member and the decorative sheet constituting the rod-shaped members 56 and 57 are made common with the square member and the decorative sheet constituting the rod-shaped members 51 to 53, respectively.

  The installer who has obtained the side parting material 46 extends the step parting material 46 from the nose 143 of the step board 141 to the nose parting material 43 related to the step board 151 (that is, the nose parting material 43 hanging from the nose 153). It is placed on the top surface. At this time, the left surface (and the rear end surface) of the horizontal parting material 46 is in contact with the right surface 3a (and the front side surface of the nosing parting material 43). As a result, the horizontal parting material 46 covers the boundary portion between the upper surface of the tread plate 141 and the right surface 3a. Further, the cut-off portion of the side parting material 46 protrudes forward from the front end surface of the nosing 143.

The installer who has obtained the first vertical parting material 47 joins the cut-off portion of the first vertical parting material 47 to the cut-off part of the horizontal parting material 46, and the rear side surface of the first vertical parting material 47 ( And the left side surface) are brought into contact with the front end surface (and the right side 3a) of the nosing 143 and are suspended from the nosing 143 over the tread 131. As a result, the first vertical parting material 47 covers the boundary portion between the nose 143 and the right surface 3a. At this time, the lower end surface of the first vertical parting material 47 is in contact with the upper surface of the tread plate 131.
The rod-shaped members 56 and 57 may be joined and joined at the time of factory shipment.

  The second vertical parting material 48 has a rectangular plate shape extending in the up-down and front-back directions (see FIGS. 10 and 13). The installer obtains the second vertical parting material 48 by cutting the plate-like member 58 indicated by the broken line in FIG. 13 in length and width according to the dimensions of the stairs 1. The plate member 58 has the same configuration as the plate member 502. The curved end surface of the plate-like member 502 becomes the rear end surface of the second vertical parting material 48. Note that the rear end surface of the second vertical parting member 48 may be a flat surface orthogonal to the left and right side surfaces.

  The installer who has obtained the second vertical parting material 48 fits the second vertical parting material 48 into the space surrounded by the step boards 131 and 141, the kick plate 142, and the first vertical parting material 47, The left surface of the vertical parting material 48 is brought into contact with the right surface 3a. As a result, the second vertical parting material 48 is arranged from the first vertical parting material 47 to the kick plate 142, and covers the lower surface of the tread plate 141 and the boundary portion between the kick plate 142 and the right surface 3a.

The horizontal parting material 46, the first vertical parting material 47, and the second vertical parting material 48 related to the step board 131 and the kick board 132 are the side parting material 46 and the first vertical parting material 46 related to the step board 141 and the kick board 142. It corresponds to the parting material 47 and the second vertical parting material 48. However, the rear end surface of the horizontal parting material 46 is in contact with the first vertical parting material 47 related to the tread plate 141.
In addition, the order which arrange | positions the horizontal parting material 46-the 2nd vertical parting material 48 in the stairs 1 is not limited to this order.

  By the way, the second vertical parting material 48 related to the step board 131 corresponds to the second vertical parting material 48 related to the step board 161. The left end surface of the upper floor parting material 41 is in contact with the right side surface of the second vertical parting material 48 related to the step board 161. That is, the upper floor parting material 41 is disposed between the protruding corner 31 and the second vertical parting material 48 related to the tread plate 161.

  Next, boundary portions between the frame 3 and the tread plate 111 and the kick plate 112 will be described. This portion is covered by the baseboard structure 6 of the stairs 1. The boundary portions between the frame 3 and the tread plates 121 and 191 and the kick plates 122 and 192 are respectively covered with the common baseboard structure 6. Illustration of the baseboard structure 6 in FIG. 2 is omitted.

The baseboard structure 6 includes a horizontal baseboard 61, a first vertical baseboard 621, and a second vertical baseboard 622. The horizontal baseboard 61 and each of the first and second vertical baseboards 621 and 622 are formed by cutting, for example, members common to the baseboard attached to the hallway.
The horizontal baseboard 61, the first vertical baseboard 621, and the second vertical baseboard 622, and the horizontal parting material 46, the first vertical parting material 47, and the second vertical parting material 48 are common. It may be a configuration.
Alternatively, the baseboard structure 6 may have the same configuration as a conventional staircase baseboard structure (for example, one described in Patent Document 1). However, in the baseboard structure 6, the first and second vertical baseboards 621 and 622 and the downside horizontal baseboard 61 are arranged in a vertical win.

  Although the L-shaped member 501 of the present embodiment is composed of two members, the corner structure 21 may be configured to include an integrally formed L-shaped member instead of the L-shaped member 501. However, the L-shaped member 501 is advantageous in terms of mass production, reduction in the number of parts, and the like, compared to the L-shaped member formed integrally. This is because the rod-shaped members 51 and 52 constituting the L-shaped member 501 can be easily obtained from a highly versatile member such as a square member around which a decorative sheet is wound, whereas the L-shaped member integrally formed is used. This is because the shaped member has low versatility and is difficult to make up compared to a simple square member.

The bar-like member 51 may have the same length as the upper floor parting material 41 at the time of factory shipment. However, the rod-like member 51 is preferably longer than the upper floor parting member 41 at the time of factory shipment. This is because if the builder cuts the rod-shaped member 51 in accordance with the stairs 1 at the construction site, the upper floor parting material 41 having a required length can be obtained with certainty. Moreover, the cutting of the rod-shaped member 51 is a cutting that is perpendicular to the longitudinal direction of the rod-shaped member 51, and therefore can be easily performed. For the same reason, the rod-shaped members 52 and 53 are preferably longer than the downstairs parting material 42 and the nose parting material 43.
In addition, the L-shaped member 501 is formed by joining the bar-shaped members 51 and 52 at 90 °, but the corner structure 21 is replaced with the L-shaped member 501 and includes two square members each wound with a decorative sheet. It is also possible to have a configuration provided with an L-shaped member formed by splicing at 90 °. However, in the case of the L-shaped member by splicing, since the end face of the square member that is not decorated is exposed outside the L-shape, it is necessary to add, for example, a decorative sheet to the end face.

The corner structures 21, 22 and the baseboard structures 6, 6,... Improve the design of the staircase 1 and protect the frame 3 at the boundary portions with the tread plates 111-191 and the kick plates 112-192. Contribute to etc. In addition, as compared with the conventional case where two horizontal baseboards are provided at each of the protruding corners 31 and 32, the corner members 401 may be provided one by one, so that the workability can be improved.
Each part constituting the corner structure 21 can be easily shaped corresponding to the dimensions of the staircase 1 if the installer performs simple processing on the rod-shaped portion of the L-shaped member, the rod-shaped member, or the plate-shaped member. Can get to. Further, when the corner structure 21 is constructed, it is not necessary to perform complicated processing (for example, notching processing or fastening processing) on each part constituting the staircase 1 or the housing 3. As a result, the corner structure 21 can be easily constructed even if the installer is an unskilled worker.
Since the corner structures 21 and 22 and the baseboard structures 6, 6,... Are generally covered with a portion that is easily visible to the user, the appearance of the staircase 1 can be improved.
