Description

The present invention relates to a runner for moving a panel along a hanger rail fixed to a ceiling to partition a space, and a moving partition device including the runner.

Large spaces such as offices, hotels, wedding halls, stores, schools, public facilities, gymnasiums, etc. are used as they are or are divided into several small spaces depending on various situations such as the number of people and the purpose of use. It is used as a space. In this way, the moving partition device is used as a device that can change the size and shape of the room according to the situation. The moving partition device is configured by suspending and supporting a panel on a runner that moves in a rail supported by a ceiling via a fixing member. The movement of the panel is performed by a person holding the panel, pushing and pulling it, and applying a propulsive force in the moving direction to the panel. By applying propulsive force to the panel, the runner moves along the rail, so that the panel can be moved and placed at a desired position along the rail.

As such a moving partition device, there is one shown in Patent Document 1 below. The moving partition device shown in this is such that two wheels rotatably supported by a suspension shaft of a runner at a predetermined interval roll on a running surface inclined inward in a hanger rail. Arranged, the wheels of the runner are formed by resin wheels, and ball bearings are interposed between the resin wheels and the suspension shaft. According to this, since the resistance between the resin ring and the suspension shaft is reduced by the ball bearing, the resin ring can rotate smoothly. Further, since the runner is supported by the two upper and lower wheels from both sides on the running surface of the rail, stable running is possible as compared with the runner having one wheel.

However, since each of the upper and lower wheels (rollers) has a built-in ball bearing, each wheel needs to have a certain height (length in the rotation axis direction). Further, two running surfaces for supporting the upper and lower wheels are formed in the rail, but since the upper running surface for supporting the upper wheels is arranged between the upper and lower wheels, it is also between the upper and lower wheels. Space is needed. For these reasons, a large space is required to incorporate the runner in the hanger rail, and there is a problem that the hanger rail becomes large.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a runner that realizes miniaturization of a hanger rail and a moving partition device including the runner.

In order to solve the above-mentioned problems, one aspect of the present invention is a plurality of runners that are movable along the inner wall of the rail, are pivotally supported by a support shaft that supports the panel, and project from above and below the inner wall of the rail. It is provided with at least a pair of vertically separated rollers that individually abut on the traveling pieces, and the upper portion of the lower roller of the pair of rollers is separated from the upper traveling piece of the plurality of traveling pieces. At the same time, it is provided at a position overlapping the traveling piece in the vertical direction.

Further, one aspect of the present invention is a moving partition device including the runner.

According to the present invention, it is possible to provide a runner that realizes miniaturization of a hanger rail and a moving partition device including the runner. Other effects of the present invention will also be described in the section of embodiments for carrying out the following inventions.

<First Embodiment>
Hereinafter, the first embodiment according to the present invention will be described with reference to the drawings. In the present specification and the drawings, components having substantially the same function are designated by the same reference numerals, so that duplicate description will be omitted.

(Device configuration)
First, the configuration of the mobile partition device including the runner according to the present embodiment will be described. FIG. 1 is a front view showing a moving partition device including a runner according to an embodiment, and FIG. 2 is a vertical sectional view around the runner. In FIG. 2, the support shaft 220, which will be described later, is not shown in a cross section for explanation, but a side surface (peripheral surface) is shown.

As shown in FIG. 1, the moving partition device 10 according to the present embodiment is suspended from a hanger rail 100 fixed to a ceiling (not shown), a runner 200 moving along an inner wall of the hanger rail 100, and a runner 200. It is configured with a supported panel 300.

(Hanger rail 100)
As shown in FIG. 1, the hanger rail 100 supports the runner 200 and forms a travel path through which the runner 200 can travel, and defines an internal space 120 in which the runner 200 can be accommodated. Is formed in an open cross section substantially U-shaped. By connecting a plurality of the hanger rails 100 and arranging them so as to form a desired traveling path, the arrangement position of the panel 300, that is, the size and shape of the space partitioned by the panel 300 is determined.

A pair of upper ribs 142a and 142b are projected on the internal space 120 side so as to face each other on both side walls 140 and 140 of the hanger rail 100 so as to face each other at a predetermined distance below them. A pair of lower ribs 144a and 144b are projected so as to define the internal space 120. The internal space 120 is divided into upper and lower two stages by a pair of upper ribs 142a and 142b, and the divided upper space is referred to as an upper space 122 and the lower space is referred to as a lower space 124, which will be described below. Further, when the pair of upper ribs 142a and 142b are not distinguished, they are referred to as upper ribs 142, and when the pair of lower ribs 144a and 144b are not distinguished, they are referred to as lower ribs 144.

The upper rib 142a on the right side in FIG. 1 of the pair of upper ribs 142a and 142b supports the upper roller 242 of the runner 200 and forms a traveling surface on which the roller travels. Therefore, the upper surface of the upper rib 142a has a higher vertical position than the upper rib 142b and is inclined so as to descend inward. On the other hand, the lower ribs 144b on the left side in FIG. 2 of the pair of lower ribs 144a and 144b support the lower roller 244 of the runner 200 and form a traveling surface on which the roller travels. Therefore, it has the same shape as the upper rib 142a. Therefore, the upper ribs 142a and the lower ribs 144b forming the traveling surface are arranged so as to be staggered up and down.

In the vicinity of the side wall 140 of the upper rib 142, the locking piece 162 is provided so as to project upward and the locking piece 164 projects downward, and the side walls 140, 140 and the upper locking piece defining the space 120a are provided. With 162, a rail joint described later for connecting the hanger rail 100 can be locked. Similarly, the locking pieces 166 are also provided in the vicinity of the side wall 140 of the lower rib 144 so as to project upward, and the side walls 140 and 140 and the locking pieces 164 and 166 defining the space 120b will be described later. The second rail joint can be locked.

(Lanna 200)
As shown in FIG. 2, the runner 200 is vertically supported by a support shaft 220 arranged in the internal space 120 of the hanger rail 100 and an upper end portion of the support shaft 220 at a predetermined interval. It has an upper roller 242 and a lower roller 244 which are connected in a direction. The upper roller 242 and the lower roller 244 have the same configuration, and when they are not distinguished, they are referred to as rollers 240 and will be described below.

The support shaft 220 has a columnar shape and a screw portion (not shown) is formed at the lower end portion thereof, and a nut 222 with a spring washer (see FIG. 1) is screwed into the screw portion through the screw portion and the panel 300. It is connected.

The upper roller 242 and the lower roller 244 are arranged so as to be located in the upper space 122 and the lower space 124 of the hanger rail 100, respectively. The upper roller 242 is in contact with the upper rib 142a, which is the traveling surface, and is not in contact with the upper rib 142b, and the lower roller 244 is in contact with the lower rib 144b, which is the traveling surface, and is not in contact with the lower rib 144a. As a result, it is possible to rotate each roller, that is, to run the runner 200 while suppressing the tilt of the runner 200 and the panel 300 in the left-right direction.

The roller 240 has a built-in bearing 246, which is a rolling bearing typified by a ball bearing or a roller bearing. The roller 240 is pivotally supported by the support shaft 220 via the bearing 246, and is rotatably rotatably around the support shaft 220 by the bearing 246. In the present embodiment, the distance x between the tip of the lower rib 144a and the tip of the lower rib 144b is formed to be less than the diameter of the bearing 246. As a result, even if the lower roller 244 is damaged and the bearing 246 falls, it is caught by the lower ribs 144a and 144b, so that the hanger rail 100 can be prevented from falling to the outside.

An annular spacer 262 inserted through the support shaft 220 is disposed between the bearing 246 of the upper roller 242 and the bearing 246 of the lower roller 244, thereby forming a gap between the upper and lower bearings 246. The contact between the upper roller 242 and the lower roller 244 is prevented. Further, below the bearing 246 of the lower roller 244, a spacer 264 whose downward movement is suppressed by the retaining ring 224 fitted to the support shaft 220 is arranged, whereby the bearing 246 of the lower roller 244 is provided. It is supported.

The roller 240 has a small diameter portion 248a formed in the upper portion thereof and a large diameter portion 248b formed in the lower portion thereof having a diameter larger than that of the small diameter portion 248a. The small diameter portion 248a is formed at a diameter whose peripheral edge is separated from the upper rib 142 in the horizontal direction, and is positioned at a position overlapping the upper rib 142 in the vertical direction. On the other hand, the large-diameter portion 248b is formed with a diameter whose peripheral edge is located vertically below the upper rib 142. By forming the small diameter portion 248a on the upper portion of the roller 240 in this way, a space 120c can be defined in the left-right direction of the small diameter portion 248a and above the large diameter portion 248b, and this space 120c becomes the roller 240. It is an interference avoidance unit that avoids interference with the upper rib 142. By arranging the upper rib 142 in this space 120c, the distance between the upper roller 242 and the lower roller 244 can be reduced as compared with the conventional runner in which the upper rib is positioned between the upper roller and the lower roller. The hanger rail 100 and the runner 200 can be miniaturized.

From the small diameter portion 248a to the large diameter portion 248b, a tapered surface 248c whose diameter is gradually increased is formed. As a result, the small diameter portion 248a and the large diameter portion 248b can be continuously formed, so that the stress concentration generated between the small diameter portion 248a and the large diameter portion 248b can be reduced, and the durability of the roller 240 can be reduced. Can be improved and the load capacity can be increased.

Further, it is preferable that the small diameter portion 248a has a thickness between the small diameter portion 248a and the bearing 246 so as to cover the side surface of the bearing 246 from the viewpoint of durability. The thickness may be appropriately designed according to the weight of the runner 200 and the panel 300, and may be at least a diameter that does not contact the upper rib 142 so as not to interfere with the rotation of the lower roller 244, that is, the running of the runner 200. .. On the other hand, since the large diameter portion 248b extends below the upper rib 142, durability and runnability can be ensured.

Further, according to the present embodiment, the durability and runnability of the roller 240 can be ensured by forming the large diameter portion 248b under the roller 240. Further, by forming the tapered surface 248c from the small diameter portion 248a to the large diameter portion 248b, improvement in durability can be expected. Further, by forming the lower rib 144 so that the distance between the tips of the lower ribs 144a and 144b of the hanger rail 100 is narrower than the diameter of the bearing 246, it is possible to prevent the bearing 246 from falling due to damage to the lower roller 244. it can.
