Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a threshold. More specifically, the present invention relates to a sill structure applicable to various partitions such as sliding doors, doors, and hanging doors.

[0002]

2. Description of the Related Art Usually, a sill provided between rooms and used for mounting various kinds of partition means such as sliding doors, doors, hanging doors and the like is often stepped on as a passage route for people entering and exiting the room. Also, the partitioning means such as sliding doors and doors are often worn and damaged during repeated use. 11 (a) and 11 (b) are side sectional views of a conventional sill 1 and a sill 1 used as a shoe slide, which are provided so as to be sandwiched between floor materials A and A, respectively. . In FIG. 11A, the sliding door B has a groove 11
Repeatedly used on "a", and used as shown in Fig. 11 (b)
In this case, since the door D is used repeatedly with the door stop 11f, the sill 1 is worn and damaged during long-term use. Also, it may be accidentally damaged during construction.

[0003]

As described above, the sill is one of the most easily damaged members of the members of a general house. Repair is quite difficult because of the resin's monochromatic finish. In addition, since the lower frame of the opening between the rooms is formed, there is a problem that once it is attached, it cannot be easily replaced. Therefore, the present invention easily replaces only a surface portion having a functional portion, such as a groove portion where a sliding door slides or a door stop of a door, even when a threshold is damaged during construction or due to long-term use. The challenge is to provide a threshold that can do this.

[0004]

SUMMARY OF THE INVENTION The present invention has been conceived to solve the above problems, and according to the present invention, a base member and a base member are provided on the base member. A cover member having a width not less than the width of the base member, and the cover member is detachably mounted on the base member over substantially the entire length in the longitudinal direction. A threshold is provided. According to the above configuration, the base
Because the cover member is detachably mounted on the base member, if the surface of the sill is damaged during construction or is worn or damaged by long-term use, if only the cover member is replaced,
It can be restored to the original threshold.

[0005] A groove may be formed in the surface of the cover member over substantially the entire length in the longitudinal direction. This makes it possible to provide a threshold suitable for attaching the sliding door. Further, a rail portion may be provided on the surface of the cover member over substantially the entire length in the longitudinal direction. This makes it possible to provide a threshold suitable for a sliding door provided with a door roller.

Further, the cover member may be blind. By doing so, the hanging door can be attached to the upper frame to provide a threshold suitable for partitioning. Further, the cover member may be a shoe slide. By doing so, the door can be attached to either the left or right vertical frame to provide a threshold with a door stop.
Further, an elongate auxiliary member may be provided adjacent to a side portion of the cover member and the base member so as to be substantially flush with a surface of the cover member, thereby forming a threshold. As described above, according to the present invention, by providing various functions to the surface of the cover member, it is possible to provide a threshold applicable to various partitions.
