Description

[Detailed Description of the Invention] This invention relates to a sliding door rail, and its purpose is to make it usable in common for the upper and lower rails that slide and guide the sliding door.

An embodiment of this invention will be described with reference to FIGS. 1 to 3. In other words, this sliding door rail A
As shown in FIG. 1, the long body 1 has a T-shaped cross section.
At the lower end of the vertical piece 1a, a fixing part 2 protruding in the right angle direction of the vertical piece 1a is provided, and at the same time, on both ends of the horizontal piece 1b, a fixing part 2 is provided protruding in the protruding direction of the vertical piece 1a so as to extend in the longitudinal direction of the main body 1. Extending wheel guide protrusions 3, 3 are provided, and a wheel guide groove 4 extending in the longitudinal direction of the main body is formed on the surface of the horizontal piece 1b opposite to the direction in which the vertical piece projects. In this case, at both ends of the lower surface of the fixed part 2,
Notch steps 5 and 6 are provided.

When using this sliding door rail A as an upper rail, turn the sliding door rail A shown in FIG.
The wheels 10 fixed to the ceiling surface 8 and attached to the upper end surface of the sliding door 9 are suspended on the wheel guide ridges 3. As a result, the wheels 10 are guided to roll along the sliding door guide protrusions 3, and the sliding door 9 can be opened and closed in the longitudinal direction of the rail. An interior decorative material 11 is attached to the ceiling surface 8 on one side of the sliding door rail A, and one end thereof is housed in the cutout step 5.
On the other side, an L-shaped mounting bracket 12 is fixed to the ceiling surface 8, the tip of the horizontal piece is housed in the notch step 6, and a decorative material 13 is fixed to the outer surface of the vertical piece with screws 14. This sliding door 9 is used, for example, as a front opening/closing door of a storage wall.

On the other hand, when using the sliding door rail A as a lower rail, keep the sliding door rail A shown in FIG. 1 in an upright position, and as shown in FIG. The wheels 19 attached to the lower end surface of the sliding door 18 are fitted into and fixed in the grooves 16, and the floor finishing material 17 is laid on the floor subfloor material 15, and the tip of the sliding door guide protrusion 3 is brought into contact with the upper surface of the end thereof. Fit and place in the groove 4. As a result, the wheels 19 are rolled and guided by the wheel guide grooves 4, and the sliding door 18 can be opened and closed in the longitudinal direction of the rail. A carpet 20 is laid on the floor finishing material 17, and decorative materials 21 are attached to both sides of the lower end surface of the sliding door 18 to hide the wheels 19 from the outside. This sliding door 18 is used, for example, as a partition wall.

In this way, since the sliding door guide protrusions 3, 3 are provided on both sides of the horizontal piece 1b of the main body 1, and the sliding door guide groove 4 is formed in the center of the horizontal piece 1b, this sliding door rail A is common to both the upper rail and the lower rail. Can be used. Moreover, since the sliding door guide groove 4 is curved and finished to have a substantially U-shaped cross section, even if dirt accumulates in the groove 4 when used as a lower rail, it can be easily swept out from the groove 4 and cleaning is easy.

The shape of the fixing part 2 of the sliding door rail A is not particularly limited, and any shape may be used as long as it can be fixed to a horizontal mounting surface and vertically supports the vertical piece 1a of the main body 1. Further, the cross-sectional shape of the sliding door guide groove 4 is not limited to only a U-shape, but may be V-shape, semicircular, etc., for example.

As described above, the sliding door rail of this invention includes a long main body with a T-shaped cross section, a fixing part provided at the tip of the vertical piece of this main body and fixed to a horizontal mounting surface to vertically support the main body vertical piece, and A wheel guide protrusion that protrudes from both ends of the horizontal piece of the main body in the direction in which the vertical piece projects and extends in the longitudinal direction of the main body, and a wheel guide that extends in the longitudinal direction of the main body on the surface of the horizontal piece of the main body opposite to the direction in which the vertical piece projects. Since it is provided with a groove, it has the effect that it can be used commonly for the upper rail and the lower rail.
