[Technical field to which the invention belongs]

 The present invention relates to a prefabricated barrier-free sill, and more particularly to a prefabricated barrier-free sill that can be simply and quickly constructed without causing almost any step on the floor surface.

[0002]

[Prior art]

 In recent years, so-called "barrier free housing" has been attracting attention for the purpose of safe and independent living for the elderly and disabled persons, by eliminating the cause of stumbling as much as possible by eliminating steps on the floor surface in the house. ing.

Conventionally, as a barrier sill that is compatible with barriers, a lower frame base made of synthetic resin is fixed to the bottom surface of a recess formed in a partition of a floor material, and a sill cover is fitted on the lower frame base. By doing so, there was one that constructed a prefabricated door sill with a step difference of 3 mm or less from the floor surface.

However, since this conventional assembly type door sill is a system in which the fitting legs of the sill cover are fitted into the gap between the end surface of the floor material and the side surface of the lower frame base, the assembly is performed depending on the position of the end surface of the floor material. However, the gap between the end surface of the floor material and the lower frame base was too large, and the sill cover was loosely fitted, making the sill cover unstable. Further, since the fitting state of the sill cover depends on the gap between the end surface of the floor material and the lower frame base in this way, considerable care must be taken when laying the floor material or when notching the concave portion of the floor material. It was

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned drawbacks of the conventional assembly-type barrier-free sill, and can be constructed reliably, simply and quickly without being affected by the position of the end surface of the floor material. It is a technical issue to provide a barrier-free sill that can be assembled.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is a channel member to be embedded and fixed in a partition part of a floor material F, and receiving parts 11, 11 having a U-shaped cross section are provided on both side edges of the channel member in an upward direction. A base member 1 formed in the longitudinal direction; and fitting legs 21, 21 which can be fitted into the receiving portions 11, 11 of the base member 1 are formed in the vicinity of both side edges in the longitudinal direction. The technical means is adopted in which the central part is composed of the cover member 2 having the supporting legs 22 formed in the longitudinal direction.

Further, in order to solve the above-mentioned problems, the present invention has, in addition to the above-mentioned means, a projection 11a formed on the inner side surface of each receiving portion 11 of the base member 1 and a cover member. The technical means that sawtooth-shaped projections 21a are formed on the side surfaces of the fitting legs 21 of No. 2 is adopted.

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail based on an embodiment shown in the accompanying drawings. 1 is an overall perspective view of a door opening portion to which the assembled barrier-free sill of this embodiment is applied, FIG. 2 is a perspective view of a main portion of the assembled barrier-free sill of this embodiment in an exploded state, and FIG. 3 is the same. FIG. 4 is a cross-sectional view of the assembled barrier-free sill in an exploded state, and FIG. 4 is a cross-sectional view of the assembled barrier-free sill in an assembled state.

As shown in FIG. 1, the barrier-free sill A of the present embodiment is arranged at the partition of the floor material F / F in the opening of the wall W, and the step difference with the floor surface is 3 mm or less. It is configured as a barrier-free door sill. It should be noted that in FIG. 1, what is indicated by the symbol T is a door frame provided around the opening of the wall W, and one inner surface of the door frame T has a door stop for opening and closing the door D. S is projected.

As shown in FIGS. 2 to 4, the assembly-type barrier-free sill A of the present embodiment includes a long plate-shaped base member 1 fixed to a recess formed in a partition of the floor members F and F. The cover member 2 is detachably fitted on the base member 1.

The base member 1 is formed in a long plate shape by extrusion molding of a synthetic resin material, and on both side edges thereof, receiving portions 11 having a U-shaped cross section are formed upward in the longitudinal direction. It is being touched. Then, convex portions 11a are formed on the inner side surfaces of the receiving portions 11 and 11 (see FIG. 3). The base member 1 is embedded and fixed to the bottom surface of the partition recess of the floor member F by wood screws 3, 3.

The cover member 2 is formed by extrusion molding of a synthetic resin material into a long plate shape slightly wider than the base member 1, and the receiving portions 11 and 11 of the base member 1 are formed in the vicinity of both side edges of the cover member 2. Fitting legs 21, 21 which are detachably fitted to the cover member 2 are formed in the longitudinal direction, and a supporting leg 22 is formed in the central portion of the cover member 2 in the longitudinal direction. Then, sawtooth-shaped projections 21a are formed on the outer surfaces of the fitting legs 21 and 21 (see FIG. 3).

By fitting the cover member 2 on the base member 1 so that the fitting legs 21, 21 of the cover member 2 are fitted to the receiving portions 11, 11 of the base member 1, It is possible to easily construct a barrier-free door sill with a step of 3 mm or less (see Fig. 4).

As described above, in the assembly-type barrier-free sill of this embodiment, the receiving portions 11, 11 having an upwardly U-shaped cross section are formed on both side edges of the base member 1, and the cover member 2 is formed there. Since the door sill is assembled by fitting the mating legs 21 of 21, the position of the end face of the floor material F laid in advance is slightly displaced, and the gap t (see the figure) is formed between the end face of the floor material F and the base member 1. 3 and FIG. 4), the clearance t does not loosen the fitting state of the receiving portion 11 and the fitting leg 21, and a stable door sill without rattling can be configured. is there.

Moreover, since the collar portions 23, 23 at the end portions of the both side edges of the cover member 2 cover the gap t, the gap t does not impair the appearance of the door sill and has a neat appearance. Barrier-free thresholds can be configured.

Further, in the barrier-free sill of the present embodiment, since a space is formed between the base member 1 and the cover member 2 in the longitudinal direction, as shown in FIG. It is also possible to pass the electric wire C through it, and wiring can be easily performed by opening the detachable cover member 2. In addition, in this embodiment, since the support leg 22 is provided so as to project from the central portion of the cover member 2, even if a large weight is applied to the center of the cover member 2, there is no fear of the space being collapsed.

The embodiment which is a specific example of the present invention is generally configured as described above, but the present invention is not limited to this embodiment, and various modifications can be made within the scope of the “claim for utility model registration”. Can be changed. For example, in the present embodiment, the upper surface of the cover member 2 is formed in a flat shape, but a projection for door stop may be formed on this upper surface, and various design changes are possible.

[Effect of the present invention]

 As described above with reference to the embodiments, in the assembly-type barrier-free sill according to the present invention, the receiving portions are formed on both side edges of the base member fixed to the recess on the floor surface, and the fitting legs of the cover member are provided there. Since they are assembled by assembling, even if the end surface position of the floor material laid in advance is slightly displaced, it is possible to construct a barrier-free sill with excellent stability without rattling, and simple and quick construction is possible. Is.

Moreover, since the flanges on both side edge portions of the cover member cover the gap due to the displacement of the floor material, the appearance is not impaired, and a barrier-free sill with a neat appearance is configured. You can
