Description

[Detailed Description of the Invention] The present invention relates to a runner for a sliding wall for movably supporting panels of the sliding wall along a guide rail.

A box-shaped guide rail that has a vertically extending guide groove in the center and horizontal guide surfaces on the left and right sides is generally used as a guide rail to support such a sliding wall. The panels of the sliding wall are supported by hanging shafts that are placed so that they can run freely along the guide rail and extend vertically from the runners.

The runner has a runner base that runs on the horizontal guide surface of the guide rail, and a hanging shaft that projects downward from the center of the base through a guide groove in the center of the guide rail, and the lower end of the hanging shaft. Support the ends of the sliding wall panels. The above-mentioned runner has main rollers on four sides of the base body that can roll on the horizontal guide surfaces of the guide rails so that the runner can freely run on the guide rails that intersect in a criss-cross pattern. In addition, when the runner comes to the cross-shaped intersection of the guide rails, and the four main wheels mentioned above fall into the guide groove, a guide surface is installed to prevent all of the main wheels from falling down. An auxiliary wheel, typically a ball runner, is provided on the underside of the base that rests on and supports the base.

Runners of the type described above are those commonly used in the past.

In addition, in order to store the sliding wall panel as described above, two runners installed on the top of the panel are moved along a pair of storage rails that are parallel to each other, and the panel is folded flat. A storage mechanism is also commonly used, in which one of the two runners mentioned above is used to store the panel safely even if there is a slight deviation in the parallelism of the pair of storage rails. A type that is attached so that it can be moved slightly horizontally in the longitudinal direction of the panel has also been used in the past.

The runners that support the panels of the conventional sliding wall as described above are configured to have a considerable degree of freedom in both the state of engagement with the guide rail and the state of engagement with the panel. When the sliding wall is opened, closed, and retracted, the panel often tilts and cannot operate properly.

An object of the present invention is to provide a runner for a sliding wall that completely prevents the panel from tilting during operation of the sliding wall of the above type, and allows the sliding wall to be reliably opened, closed, and retracted.

The runner for a sliding wall according to the present invention has a runner base that has a guide groove extending in the vertical direction at the center and runs along a guide rail with horizontal guide surfaces on the left and right sides, and a runner base that runs along a guide rail that has horizontal guide surfaces on the left and right sides of the runner base, and It extends vertically through the base body, has a hanging shaft at the lower end that supports the end of the sliding wall panel, and is attached to the four sides of the base so that it can freely run on the guide rails that intersect in a cross shape. A main roller is provided that can roll on the horizontal guide surface of the guide rail, and when the four main rollers fall into the guide groove at the cross-shaped intersection point of the guide rail, they rest on the guide surface and the base body An auxiliary wheel supporting the panel is provided on the lower surface of the base, a rolling wheel is provided at the lower end of the hanging shaft to support the panel in a horizontally movable manner, and an extension of the hanging shaft extends upward from the base. At the upper end of the section, there is a bearing that is slidably engaged with a guide section provided at the top of the guide rail, and at an intermediate section of the hanging shaft, a guide section provided at the side of the guide groove of the guide rail is provided. A bearing that is slidably engaged is provided near the lower end of the hanging shaft, and a bearing that is slidably engaged with a guide portion formed in a panel of the sliding wall.

This will be explained below with reference to the drawings.

FIG. 1 is a plan view showing an example of a sliding wall, in which 1 indicates a guide rail, 2 a panel, and 3 a panel storage section. As shown in FIG. 2, two runners 4 are attached to the top of the panel 2, and the runners 4 run on the rail 1 to move the sliding wall panel 2 along the rail. , to open and close the sliding wall. In the panel storage section 3, the two runners 4 at the top of the panel move along a pair of storage rails parallel to each other, so that the panel is folded flat as shown in FIG. In this way, when storing, one of the two runners is placed in the direction indicated by the arrow in Figure 2, so that the panel can be stored safely even if the parallelism of the pair of storage rails is not correct. It is mounted so that it can be moved horizontally.

An embodiment of the sliding wall runner according to the present invention is shown in FIG. 3, and FIG. 4 shows the runner installed in the guide rail. In these figures, 1 is a guide rail, 2 is a panel,
4 indicates a runner. The guide rail 1 has a guide groove 1a extending in the vertical direction at the center, and has horizontal guide surfaces 1b on the left and right sides of the guide groove 1a. Runner 4 shown
consists of a runner base 5 that runs along the guide rail 1, and a hanging shaft 6 that extends vertically downward from the center of the base through the guide groove 1a and supports the end of the panel 2 at its lower end. have.

The above-mentioned base body 5 has four guide rails that are movable in any direction at the intersection points of the guide rails that intersect in a cross shape (for example, the part indicated by A in FIG. 1).
A main roller 7 that rolls on the horizontal guide surface 1b of the guide rail is attached to the side. Also, when the runner comes to the above-mentioned intersection point A, the four main wheels 7 cross the guide groove 1.
An auxiliary ball runner 8 is provided on the lower surface of the base body 5 so as to rest on the guide surface 1b and support the base body 5 in order to prevent all of the main wheels from falling down when the base body 5 falls. The lower surface of this ball runner 8 is located at a slightly higher position than the lower surface of the main roller 7,
The ball runners 8 do not contact the guide surface 1b when the main rollers 7 run, but when the main rollers fall into the guide grooves 1a, they come into contact with the guide surfaces 1b and support the weight of the base 5.

A wheel 9 is attached to the lower end of the hanging shaft 6, and the support surface 10 of the panel 2 rests on the wheel, so that the panel 2 is supported so as to be slightly movable in the horizontal direction.

A thrust bearing 11 is provided at the upper end of the extension part 6a of the hanging shaft 6 extending upward from the base body 5, and is slidably engaged with a guide part 1c formed at the upper part of the guide rail 1. Further, a thrust bearing 12 is provided at the intermediate portion of the hanging shaft 6 and is slidably engaged with a guide portion 1d provided on the side of the guide groove 1a of the guide rail 1. Further, near the lower end of the hanging shaft 6, a thrust bearing 14 is provided which is slidably engaged with a guide portion 13 formed within the panel 2.

As mentioned above, the sliding wall runner according to the present invention can freely move along the guide rails installed on the ceiling using the main rollers, and at the intersections of the cross-shaped or T-shaped guide rails, the sliding wall runner can move freely along the guide rails installed on the ceiling. The action of the wheels allows for smooth movement or direction change, and in the storage section, one runner absorbs any inaccuracies in the mounting accuracy of the rails, allowing the panel to move smoothly.

However, in the present invention, guiding thrust bearings are provided above and below the runner base to prevent the panel from tilting, so the panel does not tilt when pushed, and the sliding wall can be opened and closed. Storage can be done smoothly. In addition, when storing the panel,
A guiding thrust bearing is provided to restrict the relative movement of the panel and the hanging shaft, so even if force is applied to the panel from the side for storage, the panel will be held correctly vertically, allowing for smooth panel storage. can be done.
