[Prior art]
2. Description of the Related Art Conventionally, a floor of a house has been provided with a floor member that forms the end of each finishing material at a boundary portion where the floor finish changes, that is, a so-called floor parting. For example, when the floor changes from the flooring f to the carpet c attachment, as shown in FIG. 3, the surface corresponding to the flooring f of the floor parting 1 'is cut out to form an inverted L-shaped lateral section. Thus, the end fa of the flooring f is accommodated in the notched portion.
[0003]
However, because two types of flooring f having different thicknesses are used as standard, when the floor parting 1 'having such a cross-sectional shape is used, the following problems occur.
[0004]
(1) Since it is necessary to prepare two types of floor parting 1 ′ and 1 ″ having different sizes of notches, component management becomes complicated.
[0005]
(2) In order to simplify the parts management, if one type of floor parting 1 ′ is used, the field work becomes complicated. In other words, if the standard is the one corresponding to the thick flooring f, if it is intended to correspond to the thin flooring f, a cutting operation or an embedding operation to the floor base material is required in the field (FIG. 4). reference). On the other hand, if the standard is the one corresponding to the thin flooring f, adjustment work with a spacer is required on site. Therefore, in any case, the construction becomes complicated.
[0006]
(3) Since the floor parting 1 'is fixed to the floor base material with an adhesive or the like, if the floor parting 1' is damaged, it cannot be easily replaced.
[0007]
[Problems to be solved by the invention]
The present invention has been made in view of the problems of the related art, and an object thereof is to provide a floor closing that can be applied to flooring of different thicknesses by one kind.
