Description

[Detailed explanation of the idea] The present invention relates to a door roller mounting structure for a hanging door.

Traditionally, with hanging doors, a door roller is attached to the top surface of the door body in advance.
It is inserted into a rail placed above the door body, but this is very difficult to install, and when the door roller is attached to the top surface of the door body, the door body is inserted with a jig etc. to attach it to the rail. There was a problem in that a gap was created between the upper end surface and the rail, resulting in poor appearance and difficulty in waterproofing.

The present invention has been proposed in view of the above-mentioned points, and provides a door roller mounting structure for a hanging door for the purpose of simplifying the construction of the hanging door.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the figure, 1 is a folding door type or sliding door type door body, and this door body 1 is a hanging door type, and a rail 3 is arranged above.

The rail 3 is long and square in cross section, and has a slit 12 formed in the center of its lower surface in the longitudinal direction over approximately its entire length.

Bend both edges of the slit 12 inward and upward to form the guide piece 1.
3 is present over almost the entire length.

4 is a door roller body, and this door roller body 4 has wheels 2 and 2 on both sides, respectively.
2, a guide part 14 is provided at the lower part between the two wheels 2, 2, and a rod-shaped door axle 5 is suspended in a direction perpendicular to the axis between the two wheels 2, 2. A rivet-shaped protrusion 6 larger than the diameter of the door axle 5 is formed integrally with the door axle 5 at the tip.

The wheel body 2 of the door roller body 4 is inserted into the rail 3, the wheel body 2 is placed on both side pieces 15.15 facing each other through the slit 12 of the rail 3, and the guide portion 14 is inserted into the slit 12. and both guide pieces 13.13 guide the guide part 14.

That is, when the door roller main body 4 travels within the rail 3, the two wheels 2, 2 of the door roller main body 4 roll on both side pieces 15, 15 of the rail 3, and the guide portion 14 of the door roller main body 4 moves on the guide pieces. 13 to run inside the slit 12.

Reference numeral 10 denotes a hanging fitting attached to the upper side of the door body 1. This hanging fitting 10 has a U-shaped cross section and is bent downward at a right angle from a lower piece 16 to provide a mounting piece 17. A screw hole 19 is bored in the approximate center of the mounting piece 17 of the hanging fitting 10, and a pothole 9 is bored in the approximate center of the upper piece 18.

This pothole 9 consists of a large-diameter hole 8 from the center of the upper piece 18 and a small-diameter hole 7 from the end, and the upper piece 18 of this hanging fitting 10 is arranged so that it becomes the upper end surface of the door body 1. However, since a plate 20 is provided on the upper end side of the door body 1, the pothole 9 of the hanging fitting 10 is also attached to the plate 20.
A similar potbellied hole 9' is bored in accordance with the figure.

Reference numeral 11 denotes a door wheel stopper. This door wheel stopper 11 has a substantially U-shaped cross section, and has a continuous raised step 21 approximately at the center of the top piece and the top of the center piece. A long hole 22 for height adjustment is bored in the lower part.

However, by placing the door roller body 4 inside the rail 3 in advance,
Next, the protrusion 6 at the tip of the door axle 5 of the door wheel body 4 is attached to the door body 1.
After inserting the large diameter hole 8 of the potbell hole 9, the door body 1 is moved a little laterally to insert the door axle 5 into the small diameter hole 7.

Then, the upper surface of the periphery of the protrusion 6 of the door roller body 4 and the lower surface of the periphery of the small diameter hole 7 of the hanging fitting 10 are engaged, and the door body 1 is attached to the door roller body 4.
It will be suspended in

Next, the screw body 23 is inserted into the elongated hole 22 of the door wheel stopper 11 and screwed into the threaded hole 19 of the hanging metal 10.

Then, using the elongated hole 22, the upper surface of the upper piece of the door roller stopper 11 is brought into contact with the lower surface of the protrusion 6 of the door roller body 4, and the side surface of the protrusion 6 is brought into contact with the side of the stepped portion 21. The movement of the door axle 5 is restricted, and the door roller body 4 and the door body 1 are fixed.

Here, as shown in FIGS. 2 and 3, the door wheel stopper fitting 11 and the hanging fitting 10 are attached within the door body 1,
These two metal fittings 10 and 11 are not visible from the outside, and only the door axle 5 of the door roller body 4 is visible.

The diameter of the small diameter hole 7 is slightly larger than the diameter of the door axle 5, but smaller than the diameter of the protrusion 6.

If the door body 1 is a sliding door type or a folding door type, even if the door body 1 runs while being bent, the door axle 5 is not restricted by the small diameter hole 7 and the door body 1 moves together with the door roller body 4. It is something to do.

As described above, the present invention has a protrusion larger than the diameter of the door axle integrally formed on the tip of the door axle that hangs down in a direction perpendicular to the axial direction of the wheel body of the door roller body. The upper piece is bent into a letter shape, and a potbelly hole consisting of a small diameter hole and a large diameter hole is bored in the upper piece, and a hanging bracket with a mounting piece hanging from the lower piece is attached to the upper end surface of the door body. The door wheel stopper fitting is positioned and installed in the door body, and is screwed into the mounting piece of the hanging metal fitting to abut the protrusion at the tip of the door axle of the door roller body which is fitted into the small diameter hole through the large diameter hole. Now that it is fixed, the door body can be hung from the door roller body and the rail by simply fitting the hanging fitting attached to the door roller body into the door roller body that has been inserted into the rail in advance, and attaching the door roller stopper fitting. This has the advantage of improving workability and allowing one person to do the work.Moreover, since the door roller body is inserted into the rail in advance, unlike conventional methods, the door roller body is attached to the door body and inserted into the rail. Therefore, there is no gap between the rail and the top of the door body by the height of the guide pieces on both edges of the rail slit, and the gap can be reduced as much as necessary.
Further, the width of the slit can be formed to match the width of the guide portion of the door roller body, which has the advantage of eliminating rattling and providing a good appearance.

In addition, the hanging metal fittings are bent into a roughly U-shape, a pothole is drilled in the upper part, and a mounting piece for screwing and fixing the door wheel stopper metal fittings is hung from the lower piece. It is easy to form because it is approximately U-shaped,
Further, since the hanging metal fittings and the door wheel locking metal fittings that fit into the door roller body are located within the door main body, there is an advantage that these fitting structures are not visible from the outside and do not spoil the aesthetic appearance.
