SUMMARY OF THE INVENTION An object of the present invention is to provide a runner for fittings which does not cause any swing of the hanging door in the front-rear direction during opening and closing operation of the hanging door. is there.

[0006]

A fitting runner according to the present invention comprises a pair of front and rear hanging shafts extending vertically from a mounting member of a runner dug or imposed on the upper end of a hanging door. In a runner for fittings in which runner members pivotally supported by rollers are respectively mounted on a runner, the maximum diameter portions of the front and rear rollers are shifted by a distance G from the load line L orthogonal to the rotation center to the runner member side. The cross-sectional shape of the outer periphery of the roller is substantially the same as the cross-sectional shape of the roller rolling portion of the suspension rail on which the front and rear rollers roll.

[0007]

Since the maximum diameter portion of the roller is displaced from the center of load to the runner member side, that is, inward, an inward force is always exerted by the load on the door plate on which the runner member is suspended, and the opening and closing operation of the suspension door is performed. Has no horizontal swing of the hanging door.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a fitting runner according to an embodiment of the present invention.

FIG. 1 is a front view of the runner of the present invention, and FIG.
Is a plan view, FIG. 3 is a side view, FIG. 4 is an enlarged sectional view of a runner member, FIG. FIG. 7 is a longitudinal sectional front view showing the relationship between the runner and the suspension rail, and FIG. 7 is a plan view showing another embodiment of the runner of the present invention.

Reference numeral 1 denotes a runner mounting member comprising a case 11 mounted on the upper corner of the door plate D and a holder member 12 supporting the suspension shaft 2 and being attached to and detached from the case 11. It may be a mold, but a dug-out type is preferred.

Reference numeral 3 denotes a runner member which is horizontally rotatably mounted on the suspension shaft 2 which is vertically mounted on the holder member 12, and which is a pair of front and rear and a pair of left and right four rollers 31 ... 31. Are pivotally supported on shafts 32 and 32, respectively. In this specification, left and right are defined as the direction of movement of the hanging door, and front and rear are defined as directions perpendicular to the direction of movement of the hanging door.

The roller 31 has a shape in which the maximum diameter portion 31a is shifted from the load line L, on which the load of the door plate is applied, perpendicular to the roller rotation center M, toward the runner member 3 by an interval G, and the maximum diameter portion 31a is sandwiched. With two inclined rolling surfaces 3
1b, 31c are formed, and the front and rear rollers 31, 3
Numeral 1 is pivotally supported on the runner member 3 by a shaft 32 so that the rolling surfaces 31b face each other.

In this embodiment, a pair of rollers 31, 31 is provided on the left and right so as to sufficiently withstand the load of the heavy door plate.
It is sufficient that 1, 31 is sufficient. Alternatively, as shown in FIG. 7, one of the front and rear wheels may be omitted and one wheel may be provided on the left and right.

The runner of the present invention is mounted by fitting the case 11 into a carved hole formed at the upper end corner of the door plate D and fixing it with screws.
Is completed by inserting the holder member 12 equipped with the above from the end face side of the door plate D and integrating it. This case 1
The method of integrating the holder 1 and the holder member 12 is a known technique, and a detailed description thereof will be omitted.

Reference numeral 4 denotes a suspension rail which is attached to a member such as a fitting frame on the ceiling side. Roller rolls on which the rolling surfaces 31b and 31c of the rollers 31 of the runner member 3 roll over the entire length in the longitudinal direction. Moving surfaces 41 and 42 are formed, and the roller rolling portion formed by the two roller rolling surfaces 41 and 42 is manufactured so that the cross-sectional shape thereof is substantially the same as the cross-sectional shape of the outer periphery of the roller.

In the embodiment, the rolling portions of the rollers 31, 31 are constituted by two intersecting inclined surfaces, and the rolling surfaces 41, 42 of the suspension rail 4 are formed in the shape of the rolling portions of the rollers 31, 31. The shape of the rolling portion of the rollers 31 is not limited to the slope, but may be a roller having a gently curved shape.

Next, a specific usage of the apparatus of the present invention will be described for a case where the apparatus is mounted on a hanging sliding door shown in FIGS.

In FIGS. 5 and 6, when the door plate D is moved rightward, the full load of the door plate D (actually, since the runners are attached to both ends of the door plate, a load of 1/2) is applied to the runner member. The third rollers 31 ... 31 are rolled while rotating the roller rolling surfaces 41, 42 of the suspension rail 4 in the counterclockwise direction.

At this time, the load of the door plate D is applied on the load line L passing through the center of the bearing of the roller 31,
Since the maximum diameter portion 31a is deviated toward the runner member 3 from the load line L by an interval G, a component force for pushing the roller 31 inward is generated by the interval G.

That is, when the sliding door is opened and closed, the rollers 31, 31 of the runner member 3 always exert a force that tends to approach the center side, that is, the center of the load. At this level, there is no lateral vibration and stable running can be expected.

The roller 3 in the most stable state of the roller
Since a component force when the largest diameter portion 31a of the first rail 31 falls into the valley portion of the roller rolling portion of the suspension rail 4 also acts, a stable run can be expected without the occurrence of lateral runout in combination with the eccentric load.

[0022]

As described above, according to the fitting runner according to the present invention, the upper end of the hanging shaft extending vertically from the mounting member of the runner dug or imposed on the upper end of the hanging door is provided with: In a runner for fittings in which a runner member pivotally supported by a pair of front and rear rollers on a shaft is horizontally rotatably mounted, a maximum diameter portion of the front and rear rollers is spaced from a load line L orthogonal to a rotation center to a runner member side. The shape of the roller is shifted by G.
Since the cross-sectional shape of the roller rolling portion of the suspension rail on which the front and rear rollers roll respectively is substantially the same, when the suspension door is opened and closed, the rollers of the runner member are respectively at the center side, that is, the load center. The force that tends to lean to the side always acts, and with the force in the front-rear direction pushed during the opening and closing operation of the sliding door, side running does not occur and stable running can be expected. If the lateral pressure disappears even if the lateral vibration occurs and the lateral pressure disappears, the state immediately returns to a stable state, and the roller side rolls while rubbing the side wall of the suspension rail and the side surface of the roller and the side wall of the suspension rail are reduced. There is nothing to do.
