Abstract

PURPOSE:To control slide noise to minimum by a method in which the support shafts for the upper runner in which rotary wheels are pivotally supported on both sides of a plate and for the lower travelling runner in which spherical parts are attached to the upside of a plate are screw-connected. CONSTITUTION:An upper runner 10 in which a pair of rotary wheels 12 are pivotally supported in parallel with both sides of a square plate 13 with a rotary central support shaft 11 is provided. Also, a lower travelling runner 20 in which peripheral parts 22 are attached by upwardly positioning their rotary heads 22a to both upsides 23a of a square plate 23 with a rotary central shaft 21 is provided. The support shafts 11 and 21 of both the runners 10 and 20 are screw-connected in an adjustable manner. The partition can thus be smoothly moved even when the production and attachment of hanger rails are not exact.

Description

[Detailed Description of the Invention] The present invention is a sliding partition runner, more specifically, a sliding partition runner that divides the interior of buildings such as schools, museums, wedding halls, hotels, multipurpose halls, etc., and allows free layout of each room. This invention relates to an improved sliding partition runner that can smoothly move the partition by running on the hanger rail while suspending and supporting the upper part of the partition from the hanger rail installed on the ceiling.

The main purpose of the sliding partition runner of the present invention is to move the partition in parallel along two hanger rails installed on the ceiling, so that the space can be adjusted to any size depending on the purpose of floor use. When partitions are freely separated into sections, the structural form is sufficient to cope with poor processing accuracy of the hanger rails and poor installation accuracy between the rails, ensuring reliable and smooth running of the partitions, and further improving the running speed of the partitions. This is to minimize the generation of rail sliding noise.

The sliding partition runner of the present invention will be described in detail below with reference to the accompanying drawings. First, Figure 1 is a front view of the runner, Figure 2 is a side view of the runner, and Figure 3 is a runner suspended from a ceiling hanger rail. FIG. 2 is a side view of the state in which the runner according to the present invention basically has a central support shaft 11 and an upper runner 1 that supports a plurality of rotating wheels 12 on both sides.
0, and a lower floating runner 20 having a central support shaft 21 and a plurality of spheres 22 attached to its upper surface, and the support shafts 11 and 21 are screwed together.

To explain the upper runner 10 in detail, in this one, a support shaft 11 is loosely inserted from above through a thrust bearing lla at approximately the center of a plate-like body 13 having a rectangular shape as a whole, and a support shaft 11 is loosely inserted from above through a thrust bearing lla. A pair of wheels 12 are rotatably supported in parallel, and a threaded portion 11b is provided at the end of the support shaft 11.

As shown in FIG. 3, the upper runner 10 is disposed within a hanger rail 30 and runs, but if necessary, wheels 14 for regulating the inside of the rail are attached to the four corners of the upper surface of the plate-shaped body 13. The upper runner 10 always maintains stable linear running within the rail 30 without the shaft 11 sliding against the collar 31 of the rail.

On the other hand, to explain in detail about the lower floating runner 20, this one has a support shaft 2 connected through a thrust bearing 21a approximately at the center of a plate-like body 23 whose entire body is rectangular.
1 is loosely inserted from below, and a plurality of spheres 22 with rolling heads 22a facing upward are attached to the front and rear upper surfaces 23a, and a threaded portion 21b is attached to the end of the support shaft 21. is provided.

As shown in FIG. 4, the sphere 22 has a structure consisting of a housing 22b, a plurality of small spheres 22c built into the housing, and a large sphere constituting the head 22a.
b is a small ball 22c that circulates and rolls as the large ball 22a rolls;
An annular recess 22d having a semicircular cross section is formed to accommodate the.

The material of the large ball 22a, housing 22b1, and small ball 22c constituting the sphere 22 is either steel, stainless steel aluminum, or synthetic resin material, but especially for the large ball 22a among these members, Synthetic resin materials with excellent abrasion resistance, load carrying capacity, self-lubricating properties, and anti-equilibrium shock absorption properties, long life, and good sliding properties that do not generate noise during rolling, or reinforced resins made of composites of various fibers. Preferably, it is formed using a material.

The lower floating runner 20 is disposed within the upper rail 40 of the partition M as shown in FIG.
0 and each other by screws, and are adjusted and fixed while maintaining a gap G between the ceiling and the floor that is sufficient to allow the partition M to move.

As shown in FIG. 3, the upper rail 40 of the partition M consists of a member 41 having a U-shaped cross section and a floating runner guide plate 42. The U-shaped member 41 has a support shaft 2 of the floating runner 20.
1 is loosely inserted into the slit 41a, and a strip member 43 made of a metal material such as steel or stainless steel or a synthetic resin material is provided on the lower surface of the slit 41a.
is laid, and the rolling head 22a of the floating runner 20
are always in contact with each other.

Therefore, when the sliding partition runner of the present invention having the above configuration is used, for example, as shown in FIG.
When the partition M is suspended and moved parallel to the rail (in the direction of arrow Y), the upper runner 10 runs, which makes it possible to move, while the presence of the lower runner 20 allows the partition M to move parallel to the rail (in the direction of the arrow Y). Slit 41 of rail 40
Since it is possible to move perpendicular to the direction of movement of the partition within the range of a, for example, due to poor processing during the manufacturing process of the ceiling hanger rail or faulty rail installation during the construction process, the partition moving cylinder! 1A, even if there is a variation in the distance between the rails B, the partition M moves while the distance between the runner centers is displaced in accordance with the distance between the rails B, so that not only smooth running is obtained, but also As shown in FIG. 6, the runner according to the present invention is capable of running at an inclination of the partition M due to the above structure.
You can move around avoiding obstacles on the wall.

As explained above, the sliding runner of the present invention allows smooth movement of the partition even if the hanger rail is manufactured and installed incorrectly due to the presence of the floating runner that can run perpendicular to the direction of movement of the partition. Furthermore, by forming the spherical bodies of the floating runners from a synthetic resin material, the sliding noise emitted from the upper part of the partition when the partition is moved can be suppressed to a minimum, so that the noise does not cause discomfort. Therefore, its practical value is extremely great.
