Description

  The present invention relates to a base staircase for a staircase that is arranged on a staircase and includes a first member that extends horizontally and a second member that extends vertically.

In a conventional staircase called a box-shaped staircase, a groove in which an end portion of a tread board and a kick board enters is formed on a side plate surface, and then the tread board and the kick board are attached. Normally, in this method, the tread board, the kick board, and the side board are constructed in the same tree type and color so that they are excellent in aesthetics when constructed with high accuracy.
However, advanced technology is required for construction, and it is necessary to process the decorative surface directly with a tool such as a chisel, especially when processing the mounting part of the tread plate and the kick plate to the side plate, so the decorative surface will not be damaged In addition to using nerves, there is a drawback that a gap is likely to be formed between the tread.

Therefore, in recent years, a simpler method has been proposed and generalized especially in low-cost houses. This is a staircase generally constructed as a staircase staircase, in which the upper surface of the sagittal girder corresponding to the side plate of a box-shaped staircase is processed into a sawtooth shape, and a step board and a kick board are placed on this (for example, (See cited reference 1).
According to this method, it is not necessary to process a complicated groove into which the tread board or the kick board enters, and only a simple saw-tooth process is required to mount the tread board or the kick board. Moreover, since the sasara girders are completely hidden behind the stairs after the completion of construction, there is no need for cosmetic materials, and there is no need to use nerves so as not to damage the decorative surface like the side plates in box-type stairs.

In this stairs, the treads are placed directly on the girders, so both treads are in direct contact with the side plates. In this state, a gap (about 5 to 10 mm) between the end of the tread board and the side plate is conspicuous. Therefore, a method of concealing this gap is usually performed with a member called a staircase skirting board.
As for the staircase skirting board, the tread board and the kick board are continuous by about 13 steps at an angle of about 90 degrees. Unlike the skirting board used in the room, the L In many cases, construction was performed by combining character-shaped basic units (see, for example, cited document 2).

  Such a stair skirting board is a planar U-shaped folded staircase whose direction changes by 180 degrees at the beginning and ascending, and a flat L-shaped bent staircase whose direction changes by 90 degrees at the beginning and ascending. Although it is also used for the turning staircase that is the turning part, in the straight staircase, the tread board (step nose) and the kick board are at right angles to the side board (that is, the base stair board), as shown in FIG. On stairs, the angle is not always a right angle.

If the angle formed between the step board F and the kick board K and the surrounding staircase skirting board 100 is not a right angle, a gap is likely to be generated between the surrounding staircase skirting board 100 and the step board F or the kick board K. Also, depending on the angle between the footboard F and the staircase skirting board 100 (parts B and E in FIG. 15), if the rear end of the staircase skirting board 100 is not cut obliquely, a gap is surely generated. .
When the gap is generated, not only the beauty is impaired, but also dust enters the gap, which is not preferable.

  Accordingly, as shown in FIGS. 16 to 20, the portions of the stair skirting board 100 that abuts against the front surfaces of the nose N and the tread board F are cut obliquely as necessary so that the gap does not occur, and the front ends thereof. A stair skirting board 100 is disclosed for contacting the nose N and the tread board F (see, for example, Patent Document 3).

This staircase skirting board 100 is arranged in part A (FIG. 16), part C (FIG. 18) and part D (FIG. 19) of FIG. The rear edge is cut vertically.
On the other hand, in the parts B and E of FIG. 15, if the staircase skirting board 100 whose rear end is cut vertically is arranged in the same manner, the staircase skirting board 100 for the staircases 100 is related to the rotation angle of the tread board F and the kick board K. The appearance of the pierce of the pierce appears in the appearance, and the aesthetic appearance is impaired, and a gap is formed with the exposure of the piercing of the lip. Therefore, as shown in FIG. 17 and FIG. Each is cut diagonally to prevent it.
In this way, the rear end of the staircase skirting board 100 is brought into contact with both the front surface of the nose N and the front surface of the kick plate K.

However, the nose N and the kick plate K having different positions in the front-rear direction are simultaneously applied to the staircase skirting board 100 regardless of whether the cut is perpendicular or oblique to the surface of the staircase skirting board 100. Therefore, if the processing accuracy of the surrounding staircase skirting board 100 is not high, the gap between the surrounding staircase skirting board 100 and the nose N or between the surrounding staircase skirting board 100 and the kick board K will eventually be a gap. Will occur.

(First embodiment)
With reference to FIG. 1 thru | or FIG. 7 and FIG. 15, the baseboard 200 for surrounding stairs concerning 1st embodiment of this invention is demonstrated.
The surrounding staircase skirting board 200 includes a first member 21 and a second member 22. In particular, the shape of the second member 22 is characteristic.
Further, the circuit stairs to which the circuit board 200 for the circuit staircase is attached includes a vertically extending kick board K and a horizontally extending tread board F, and the nose N which is the front end portion of the tread board F is higher than the kick board K. Protrusively forward. Further, at least one end (the back side of the drawing in FIG. 1) of the kick board K or the tread board F is in contact with the side board.
Then, while changing the height of the tread board F in order, the respective positions of the combination of the tread board F and the kick board K are rotated as shown in FIG. The folding part of the folding staircase has six steps.
Note that the right side of the drawing in FIG. 1 and the like is the front of the stair skirting board 200, and the left side of the drawing is the rear. The same parts as those shown in the conventional example are denoted by the same reference numerals.

The first member 21 is in contact with the side plate S and extends horizontally along the upper end of the side plate S side (outer peripheral side) of the tread plate F in the state of being attached to the surrounding staircase, and the first main body portion 21a and the first protruding portion 21b. Consists of.
The 1st main-body part 21a is a horizontally long plate shape, and the 1st packing 23 which contact | connects the tread board F is attached to the lower end.
And the 1st protrusion part 21b inclines to the front side upper direction from the approximate center of the front end of the 1st main-body part 21a, and protrudes in triangular shape.

The first packing 23 is in contact with the upper surface on the outer peripheral side of the step board F, and the length in the front-rear direction of the first packing 23 is equal to the length in the front-rear direction of the first main body 21a. It is also equal to the length obtained by subtracting the length of the other second member 22 in the front-rear direction from the length.
Further, the front end of the first main body portion 21a is flush with the front end of the nose N, and the upper end of the first main body portion 21a and the upper end of the first protruding portion 21b are flush.
The angle formed between the inclined portion of the first protrusion 21b and the upper end of the first member 21 is 45 °.
And the 1st protrusion part 21b and the 2nd protrusion part 22b are spliced, and the angle which the 1st member 21 and the 2nd member 22 make is about 90 degrees.

The second member 22 is in contact with the side plate S and extends vertically in front of the kick plate K on the side plate S side, and includes a second main body portion 22a and a second projecting portion 22b.
The 2nd main-body part 22a is a vertically long plate shape, and the 2nd packing 24 which contact | connects the kick board K is attached to the rear end.
And the part from the front end of the upper end of the 2nd main-body part 22a to the approximate center protrudes in a rectangular shape as the 2nd protrusion part 22b, and also inclines to the front upper direction from the upper end of the rear end of the rectangular protrusion part. And project in a triangular shape.

The second packing 24 is in contact with the entire front surface of the outer peripheral side end portion of the kick plate K, the vertical length of the second packing 24 is equal to the vertical length of the second main body portion 22a, and the vertical direction of the kick plate K. Is equal to the length obtained by subtracting the thickness of the other step board F from the length of
Both the second packing 24 and the first packing 23 have a substantially tongue-shaped cross section projecting from the front side to the back side, and the curved projecting portion is in a closed state when no external force is applied, but this can be opened. .
Moreover, the upper end of the 2nd main-body part 22a is flush | planar with the upper end of the kick board K, and is in contact with the lower end of the nosing N (tread board F).
Further, the front end of the second main body 22a, the front end of the rectangular portion of the second protrusion 22b, and the front end of the triangular portion of the second protrusion 22b are flush with each other.

Further, the height of the rectangular portion of the second protruding portion 22b is equal to or higher than the height obtained by adding the thickness of the nose N to the height from the lower end of the first main body portion 21a to the lower end of the first protruding portion 21b. It is less than the height obtained by adding the thickness of the nose N and the width of the first packing 23 to the height from the lower end of the main body 21 a to the lower end of the first protruding portion 21 b.
That is, there is an allowance in the allowable value of the height of the rectangular portion of the second protrusion 22b by the amount of expansion and contraction of the first packing 23.
The length obtained by adding the width (thickness) of the second packing 24 from the rear end of the rectangular projecting portion of the second projecting portion 22b to the rear end of the second main body portion 22a is from the kick plate K of the nose N The front end of the nose N is in contact with the rear end of the rectangular protrusion of the second protrusion 22b, which is equal to the protrusion amount. This also means that the allowable value has a width corresponding to the amount of expansion / contraction of the second packing 24, similarly to the amount of expansion / contraction of the first packing 23.

Further, as shown in FIG. 2, the rear end of the second protrusion 22 b is inclined backward from the back side in contact with the side plate S toward the front side. That is, the thickness direction inclined portion 22c is a tip having a sharp front side and a rear side.
The angle of the tip of the thickness direction inclined portion 22c is less than 45 ° in plan view. The angle may be exactly 45 ° for convenience of processing.
The thickness direction inclined portion 22c is formed from the lower end of the second protrusion 22b to a height substantially equal to the thickness of the nose N.

When the stair skirting board 200 configured in this way is arranged in the combination of the step board F and the kick board K of each of the staircases, the result is as shown in FIGS.
That is, the five steps A to E shown in FIG. 15 are all made of the same shape of the first member 21 and the second member 22 and the staircase 200 for the staircase is used. While elastically contacting the front surface, the tip of the thickness direction inclined portion 22c of the second projecting portion 22b abuts against the front surface of the nose N oppositely. In other words, only the rear end of the second projecting portion 22b is inclined in the thickness direction in the portion of the staircase skirting board 200 that comes into contact with the surrounding stairs (the nose N and the kick plate K).
15A and 15B, the second packing 24 is in the closed state as shown in FIGS. 3 to 7, but the second packing 24 is in the open state as shown in FIG. You may fill the gap.
3 to 7, the front surface of the nose N is represented by a two-dot chain line. Further, hatching of the cross section of the nose N (tread board F) is omitted in order to prevent deterioration of the visibility of the drawing.

According to the surrounding stair skirting board 200 configured as described above, the second packing 24 attached to the second main body 22a is in elastic contact with the front surface of the kick plate K, and the inclined portion 22c of the second protrusion 22b. Since the tip of the abutment comes into contact with the front surface of the nosing N, the gap is absorbed by the second packing 24, and even if the processing accuracy is not high, the second projecting portion 22b and the nosing N It is hard to produce a gap between the two.
Further, since the second packing 24 comes into elastic contact with the front surface of the kick plate K, the appearance surface of the kick plate K is hardly damaged, and there is almost no squeak noise accompanying the contact on the kick plate K.
Further, since the second packing 24 itself becomes a protective material, only the inclined portion 22c of the second protruding portion 22b needs to be protected during transportation of the surrounding stair skirting board 200.
In addition, the height of the inclined portion 22c is substantially equal to the thickness of the nosing N, and the inclined portion 22c is opposed to the nosing N. Therefore, the inclined portion 22c that is easily damaged during transportation or the like is the minimum necessary size.

  In addition, since the angle of the tip of the inclined portion 22c is less than 45 ° in plan view, regardless of the rotation angle of the combination of the tread board F and the kick board K, when the stair skirting board 200 is arranged on the turning staircase, The wooden face of the surrounding staircase skirting board 200 does not appear in the appearance, and there is no gap due to the exposure of the wooden face. Therefore, aesthetics can be improved reliably.

Moreover, regardless of the rotation angle of the combination of the tread board F and the kick board K, the angle of the tip of the inclined portion 22c is made constant, so that the cost is reduced compared to the case where there are several types of angles.
That is, even if the number of steps of the staircase is increased or decreased, or even if it is a straight staircase, one kind of base staircase 200 for the staircase can be used, so that the manufacturing cost and product management cost can be reduced.

(Second embodiment)
Next, with reference to FIG. 9 thru | or FIG. 15, the baseboard 200 for surrounding stairs which concerns on 2nd embodiment of this invention is demonstrated. In addition, the same code | symbol was attached | subjected to the same part as 1st embodiment.

The surrounding staircase skirting board 200 includes a first member 21, a second member 22, and a third member 25.
The 1st member 21 consists of the 1st main-body part 21a and the 1st protrusion part 21b.
The 1st main-body part 21a is horizontally long rectangular shape, and the 1st packing 23 which contact | connects the tread F is attached to the lower end.
Moreover, the 1st protrusion part 21b inclines to the front side upper direction from the lower end of the front end of the 1st main-body part 21a, and protrudes in triangular shape.

The 2nd member 22 consists of the 2nd main-body part 22a and the 2nd protrusion part 22b.
The 2nd main-body part 22a is a vertically long rectangular shape, and the 2nd packing 24 is attached to the rear end.
Further, the second projecting portion 22b is inclined in the upward direction from the upper end of the rear end of the second main body portion 22a and projects in a triangular shape.
The second packing 24 is divided into upper and lower parts along the line of the lower end of the nosing N, and the portion 24A contacting the upper nose N front end is in a closed state, while the lower portion 24B is in an open state.
An open state portion 24 </ b> B of the second packing 24 is covered from the front side of a front portion of a third member 25 to be described later, and the tip back surface of the second packing 24 is in elastic contact with the third member 25.

  And the 1st protrusion part 21b and the 2nd protrusion part 22b are spliced, and the angle which the 1st member 21 and the 2nd member 22 make is about 90 degrees.

The third member 25 has a vertically long rectangular shape, is provided in contact with the front end of the kick plate K, and closes the gap between the open state portion of the second packing 24 of the second member 22 and the kick plate K.
Further, the rear end of the third member 25 is a thickness direction inclined portion 25c inclined backward from the back side in contact with the side plate S toward the front side.

When the staircase skirting board 200 configured in this way is arranged in the combination of the step board F and the kick board K of each of the staircases, the result is as shown in FIGS.
That is, the five steps A to E shown in FIG. 15 are all made of the same shape of the first member 21, the second member 22, and the third member 25. Unlike the form, the upper part of the second packing 24 is in elastic contact with the front surface of the nose N, and the tip of the thickness direction inclined portion 25c of the third member 25 is in contact with the front surface of the kick plate K.

According to the stair skirting board 200 configured as described above, the upper portion 24A of the second packing 24 is in elastic contact with the front surface of the nose N, and the tip of the thickness direction inclined portion 25c of the third member 25 is the kick plate. Since it abuts against the front surface of K, the gap is absorbed by the second packing 24, and even if the processing accuracy is not high, any of the space between the second packing 24 and the nose N and between the third member 25 and the kick plate K It is difficult for gaps to occur.
In addition, since the upper portion 24A of the second packing 24 elastically contacts the front surface of the nosing N, the appearance surface of the nosing N is hardly damaged. Further, there is almost no squeaking noise in the nose N.
Moreover, since the lower part 24B of the second packing 24 is opened and covers the third member 25 from the front side, the distance between the second member 22 and the third member 25 can be adjusted by the length of the substantially tongue-shaped portion. is there.

  In the first and second embodiments, the angles of the tips of the thickness direction inclined portions 22c and 25c are less than 45 ° in plan view, but the present invention is not limited to this.

  Further, the angle of the tips of the thickness direction inclined portions 22c and 25c is constant regardless of the rotation angle of the combination of the tread board F and the kick board K. However, the present invention is not limited to this. 200 may be used.

In addition, the second packing 24 is attached to either one of the part that abuts on the nose N and the part that abuts on the kick plate K, and the other is only provided with an inclination in the thickness direction. Instead, packing may be provided on both. However, in this case, the manufacturing cost increases.
In addition, although the surrounding staircase has six steps, it is not limited to this.
