Description

[Detailed description of the invention] This invention prevents dirt, etc. from entering the grooves of the floorboard body, makes walking safe, allows smooth drainage of water from the floor surface, and prevents dirt from entering the grooves of the floorboard body. In order to prevent the groove cover from coming out,
Bead-shaped protrusions are provided at both ends along the longitudinal direction of the elongated plate, and legs are expanded outward on the back side of the elongated plate and inside the protrusions. This invention relates to a floorboard in which a vertically installed groove cover is fitted into a groove in a floorboard main body.

Conventionally, in order to attach a floorboard to a joist, etc., a groove is provided along the longitudinal direction approximately in the center of the floorboard, and a groove cover is fitted into the groove to prevent dirt and dust from accumulating in the groove. The floorboards made are known.

However, since the floorboard is long and made entirely of hard material, especially if there is a dimensional error in the groove or the groove cover, the groove can be completely blocked by the groove cover, preventing the intrusion of dust, etc. It was difficult to prevent this.

Also, if the groove cover fitted into the groove is pulled out of the groove, or if a part of the groove cover protrudes from the top surface of the floorboard body,
It was also dangerous to trip over while walking.

This invention improves the drawbacks of the conventional floorboards mentioned above, prevents dirt and dust from entering the grooves, makes it safe for walking, and also makes drainage on the floorboard surface smooth. This is a floorboard designed for this purpose.

Hereinafter, embodiments of the floorboard according to the present invention will be described with reference to the drawings.

Fig. 1 is an exploded perspective view of the floorboard, Fig. 2 is a side sectional view, and Fig. 3 is an explanatory diagram when fitting the groove cover. top surface 2
A groove 3 is formed approximately in the center of the groove.

Reference numeral 4 denotes a groove cover that fits into the groove 3 of the main body 1, and its entire length is the same as that of the floorboard main body 1, and a bead-shaped protrusion 6 is provided at both ends along the longitudinal direction of the long board 5. It is a provision.

Further, on the back surface of the elongated plate body 5 and inside the protruding body 6, two legs 7 which are widened outward are vertically disposed.

An engaging protrusion 8 is provided on the outer side of the lower part of the leg body 7, and this engages with an engaging protrusion 9 that projects from the lower part of the inner wall of the groove 3.

This groove cover 4 has bead-shaped protrusions 6 at both ends of the elongated plate body 5 in contact with the upper part of the inner wall of the groove 3 of the floorboard main body 1,
The groove cover 4 is fitted into the groove 3 by closing the opening of the groove 3, positioning the upper surface of the elongated plate 5 and the upper surface of the floorboard body 1 so that they are substantially on the same plane. It is.

When fitting the groove cover 4 into the groove 3 of the floorboard main body 1, as shown in FIG. Insert it and push it in.

Then, the lower part of the leg body 7 expands again within the groove 3, and the engagement protrusion 8 engages with the engagement protrusion 9 of the groove 3.

At the same time, the projecting body 6 on the ball edge of the elongated plate 5 presses the inner edge of the opening of the groove 3, thereby sealing the opening of the groove 3.

In this case, since the projecting body 6 has a beaded edge, it can easily fit into the opening of the groove 3.

In addition, in FIG. 3, 10 is a joist, and 11 is a fastener (screw) fastened to the joist 10.

The floorboard main body 1 and the groove cover 4 are made of commonly used plastics, such as polyvinyl chloride, polyethylene, polypropylene, FRP (glass fiber reinforced plastic).
etc., or may be made of metal, wood, etc.

As described above, the present invention provides bead-shaped protrusions 6 at both ends along the longitudinal direction of the elongated plate 5, and has legs on the back surface of the elongated plate 5 and inside the protrusions 6. The body 7 is expanded outwardly and hung vertically, and an engaging protrusion is provided at the lower end of the leg body to form a groove cover 4, and the groove cover 4 is formed into a recess with an engaging protrusion 9 at the lower part of the inner wall. Since the flooring material is fitted into the groove cover, the bead-shaped protrusions provided at both ends of the elongated plate of the groove cover tightly fit into the opening of the groove, and the elongated plate seals the groove. Since the grooves are closed, it becomes difficult for dirt and the like to enter the grooves of the floorboard body.

Since bead-shaped protrusions are provided at both ends of the elongated plate body of this groove cover, even if there is some dimensional error in the concave groove of the floorboard body or the groove cover, the outer peripheral surface of the protrusion will be This is suitable because it closes the opening of the groove, and since the outer peripheral surface of the bead-like protrusion acts as a guide to the groove, it is easy to fit into the opening of the groove.

In addition, since the protrusion is a beaded edge, it becomes a smooth protrusion,
Moreover, since the upper surface of the elongated plate and the upper surface of the plate-top main body are substantially on the same plane, it is safe to walk without tripping.

Furthermore, since the engaging protrusions on the legs of the groove cover engage with the engaging protrusions on the groove, the groove cover does not come out of the groove.

In addition, drainage on the floorboard surface becomes smoother, and the bead-shaped protrusions on the long board provide a nice finish at both ends of the long board. Moreover, it becomes a reinforced groove cover, so it can be used as a recessed groove. The floorboards of the present invention fitted into the floorboards also have the effect of becoming beautiful and strong.
