  However, in the skirting board structure described in Patent Document 1, foreign matter such as dust and dust accumulates in a gap formed between the lower width timber and the floor surface, which may impede ventilation.

  In order to solve the above-described problems, an object of the present invention is to provide a baseboard structure having a novel configuration in which aeration is not hindered by foreign matters such as dust and dust.

In order to achieve this object, the present invention according to claim 1 is directed to a baseboard structure composed of an upper width timber fixed to a wall and a lower width timber fixed to a floor. A space extending continuously in the horizontal direction is provided between the lower width timber and the lower width wood at a height position where the rear portion enters the space and the front portion protrudes indoors and does not reach the lower end surface of the wall. It is fixed to the floor as having an upper end, whereby a gap communicating with the space is provided at a position higher than the floor surface between the upper width wood and the front portion of the lower width wood .

According to a second aspect of the present invention, in the baseboard structure according to the first aspect, a filter is provided between the lower end surface of the wall and the upper surface of the rear portion of the lower width wood so as to substantially cover the gap. It is characterized by that.

According to a third aspect of the present invention, in the skirting board structure according to the first or second aspect, the upper width timber is fixed to the wall in a state where the flat lower surface is substantially flush with the lower end surface of the wall. A protrusion projecting downward is provided on the surface side of the flat lower surface, and an obliquely downward air passage is formed on the indoor side of the gap .

  The present invention according to claim 4 is characterized in that, in the skirting board structure according to any one of claims 1 to 3, the lower width timber is detachably fixed to the floor by a locking metal fitting.

  According to the first aspect of the present invention, the gap for ventilation is formed between the upper width timber fixed to the wall and the lower width timber fixed to the floor, and is located away from the floor surface. Therefore, foreign matter such as floor dust and dust hardly accumulates in the gap, and good ventilation can be ensured over a long period of time.

According to the second aspect of the present invention, since the filter is provided inside or facing the gap, even if the foreign matter enters the gap from the indoor side, the foreign matter is The effect of ensuring good ventilation over a long period of time is exhibited more significantly without entering the inner ventilation space and accumulating.

  According to the third aspect of the present invention, since the indoor air passage by the gap is formed obliquely downward, it is possible to more effectively prevent foreign matter from accumulating in the gap, and the gap can be seen from the indoor side. Since it becomes difficult, the design is preferable.

  According to the fourth aspect of the present invention, since the lower width timber is detachably fixed to the floor by the locking metal fitting, the lower width timber can be freely attached, removed, exchanged, etc., and The work at that time is also easy. Therefore, for example, even if the lower width timber is damaged or the floorboard needs to be replaced or repaired, the lower width timber is removed and replaced with a new one, or after the floorboard replacement or repair work, etc. The work of attaching can be easily performed, and the floor board or the like is not damaged at that time.
