DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic material sill and a shoe slide in which a synthetic material and a base material are joined.

[0002]

2. Description of the Related Art Conventionally, sills and shoe slides have been known to be made of processed wood or integrally formed of synthetic material.

[0003]

When the material of the sill is wooden, the sill can be made of various thicknesses because it is relatively easy to process, but there is a problem in load resistance and abrasion resistance. Was. In addition, synthetic materials are excellent in load resistance and abrasion resistance, but since they are integrally molded with molds, each mold is required to make various thickness thresholds, so the cost is high, etc. There was a problem. Also, a threshold where a synthetic material and a base material are joined was not known.

[0004]

According to the present invention, however, since laminated woods having different numbers of laminated layers can be joined to an integrally molded synthetic material, thresholds having various thicknesses can be formed. The point could be solved.

That is, the present invention is characterized in that a sill groove is provided in a longitudinal direction of an upper surface of a synthetic sill material in which a synthetic material is overlapped and joined on a base material, and an overhang portion is provided on an upper side surface of the synthetic material. This is the threshold for synthetic materials. According to another invention, a plurality of fitting ridges are continuously provided at predetermined intervals on a lower surface of a synthetic material, and the fitting ridges are fitted into a plurality of grooves provided on an upper surface of the base material to form a synthetic sill material. A composite sill characterized in that a sill groove is provided in a longitudinal direction of an upper surface of the composite sill material and a thin overhang is provided on an upper side surface of the synthetic material. In another invention, the base material is a laminated wood, and a plurality of uneven portions are provided in both longitudinal directions of the fitting ridge portion, and the overhang portion is formed on one side of the upper side surface of the synthetic material. Or it is provided on both sides. Still another aspect of the present invention is a synthetic material shoe slide, wherein an overhang portion is provided on an upper side surface of a synthetic sill material in which a synthetic material is overlapped on a base material and joined.

[0006] The synthetic material described above is obtained by mixing and kneading a synthetic resin with wood powder as a filler. Examples of the synthetic resin include polystyrene and polyvinyl chloride. Although wood flour was used as the filler, it is not limited to the wood flour as long as it has the same effect. The laminated wood in the above is a veneer board, a thin wooden board or the like, which is sequentially adhered with glue and pressed. Laminated wood of various thicknesses can be produced depending on the number of veneer boards or the like to be laminated.

[0013] Since the present invention has the above-described configuration, if laminated woods having different numbers of laminations are joined to the integrally-formed synthetic material 1, thresholds having various thicknesses can be formed.

[0014]

Embodiment 2 A threshold of a synthetic material according to another invention will be described with reference to FIG.

A plurality of sill grooves 7 and 7a are provided in the longitudinal direction of the upper surface of the elongated laminated wood 3, and the elongated synthetic material 1, 1a and 1a are provided on the surface of the laminated wood 3 excluding the sill grooves 7 and 7a.
The composite sill 5 is formed by superimposing and joining the “b”. Next, sill rails 12, 12 a of different materials are fitted into sill grooves 7, 7 a communicating with the synthetic materials 1, 1 a, 1 b of the synthetic sill material 5, and project from the side surface of the laminated timber 3 of the synthetic sill material 5. The overhanging portions 8 and 8a are provided on the upper side surfaces of the synthetic materials 1 and 1b to form a synthetic material sill 9. In the above, the laminated wood 3 and the synthetic materials 1, 1a, 1b are joined to the grooves 4 on the upper surface of the laminated wood by fitting the fitting ridges on the lower surfaces of the synthetic materials 1, 1a, 1b. Are identical.
