The moving partition runner disclosed in Patent Document 1 includes an annulus fitted to the outer peripheral surface of the middle traveling wheel main body. The annulus includes the ring main body having a rolling outer peripheral surface and the rolling ring. A vibration damping body is provided between the dynamic outer peripheral surface and the outer peripheral surface of the traveling wheel body. According to such a configuration, the moving partition runner can prevent the vibration that tends to occur when the traveling wheel rolls on the rail by the damping body.

JP-A-11-172998

  However, in the conventional moving partition runner, the ring main body having the rolling outer peripheral surface of the traveling wheel is made of metal, so that while the vehicle is traveling on the linear portion of the rail, the vibration damping body causes noise. Even if the generation can be prevented, there is a problem that a large impact sound is generated when the traveling wheel collides with the rail inner wall surface at the intersection of the rails.

  Therefore, the present invention has been made in view of such a problem, and the object of the present invention is to suppress the generation of a large impact sound even when the traveling wheel collides with the rail inner wall surface at the rail intersection. It is an object of the present invention to provide a movable partition runner and a movable partition including the same.

  In order to solve the above-described problems, according to the present invention, in a moving partition runner that travels along a hanger rail and supports a suspended panel, a roller supported by a support shaft so as to be horizontally rotatable, A moving partition that is provided on an outer peripheral surface and is capable of abutting against an inner wall surface of the hanger rail, wherein the buffer portion is provided with a space for deforming the buffer portion. Runners are provided.

  According to this configuration, since the buffer portion is formed on the outer peripheral surface of the roller and the buffer portion is provided with a space for deforming itself, even if the roller collides with the rail inner wall surface at the rail intersection. The generation of a large impact sound can be suppressed by the buffering effect caused by the deformation of the space accompanying the deformation of the buffer part. The direction in which the buffer portion is deformed is an appropriate direction such as the radial direction or the axial direction of the roller. In addition, the volume of the space may be reduced by the deformation of the buffer portion, or the volume of the space may be unchanged although the shape of the space is changed.

  In addition, by providing the runner with a vibration damping function, it is possible to adopt an existing one without adding a vibration damping device between the rail side and the base, which improves maintenance and is advantageous in terms of cost. The degree of freedom in design is also improved.

  The present invention can be applied in various ways. For example, the buffer portion includes a base portion attached to the outer peripheral surface of the roller, and a protrusion portion that protrudes from the base portion in the outer peripheral direction of the roller, and the space is formed between the base portion and the protrusion portion. You may make it do. In this way, the buffer portion has a protruding portion protruding in the outer peripheral direction from the base portion attached to the outer peripheral surface of the roller, and the protruding portion can contact the inner wall surface of the hanger rail. Even if the roller collides with the inner wall surface of the rail, the generation of a large impact sound can be suppressed by the buffering effect of the protruding portion that is deformed by the deformation of the space.

  Further, one end of the protruding portion may be connected to the base portion in a cantilever state. By adopting a structure in which one end of the protruding portion is connected to the base portion in a cantilevered state, the buffer portion can be easily molded, and the space between the protruding portion and the base portion is hollow when contacting the inner wall surface of the rail. Since it becomes a state, the buffering effect can be improved.

  Furthermore, according to the present invention, there is provided a moving partition characterized by including any of the above-described moving partition runners.

  According to the movement partition runner of the present invention and the movement partition provided with the same, even when the traveling wheel collides with the rail inner wall surface at the intersection of the rails, generation of a large impact sound can be suppressed. Other effects of the present invention will also be described in a mode for carrying out the invention described later.

FIG. 3 is a partial cross-sectional view showing a state of the runner 200 in a state where the runner 200 is in contact with the inner wall surface of the hanger rail 110.

  As shown in FIG. 1, the moving partition 100 according to the present embodiment is hung on the hanger rail 110 on which the edge of the ceiling panel P is placed, the runner 200 that travels along the hanger rail 110, and the runner 200. Panel 120 to be provided.

  The hanger rail 110 is arrange | positioned at the upper part of the ceiling panel P, and forms the driving | running route where the runner 200 drive | works. The travel route of the runner 200 is configured by connecting the hanger rail 110 in series, L-shape, T-shape, cross shape, and the like. As shown in FIG. 1, the hanger rail 110 is a space in which the upper part 110 a accommodates the runner 200, the lower part 110 b is opened, and a suspension bolt 240 described later of the runner 200 passes therethrough. The lower part 110b of the hanger rail 110 passes through the opening K of the ceiling panel P and protrudes into the room, and the end part 211 mounts the edge part on the indoor side of the ceiling panel P.

  As shown in FIG. 1, the hanger rail 110 is provided with ribs 112 in an internal space in which the runner 200 can be accommodated, and is divided into two upper and lower spaces by the ribs 112. Therefore, the hanger rail 110 accommodates two upper and lower rollers 220 described later in two upper and lower spaces. The hanger rail 110 is provided with a cushioning material 114 that alleviates the impact when the runner 200 collides. The cushioning material 114 is provided on the inner wall surface 110 c of the hanger rail 110 and the rib 112.

  As shown in FIG. 1, the panel 120 is suspended by a runner 200, and an upper end portion is connected to a suspension bolt 240 described later of the runner 200. As a result, the panel 120 is suspended so as to be movable along the hanger rail 110.

  Next, the runner 200 that is a characteristic component of this embodiment will be described.

  The runner 200 travels along the hanger rail 110 and moves the panel 120. As shown in FIG. 1, the runner 200 is provided on two upper and lower rollers 220 supported by a collar (support shaft) 210 so as to be horizontally rotatable, and on the outer peripheral surface of the roller 220, and the inner wall surface 110 c of the hanger rail 110. The buffer part 230 which can contact | abut to this buffer material 114, and the suspension bolt 240 with which the panel 120 is connected are provided.

(Roller 220)
The two upper and lower rollers 220 are rotatably supported by the collar 210 via bearings 250 as shown in FIG. A notch 222 is formed over the entire outer periphery of the upper end of each roller 220. A buffer part 230 is provided in the notch part 222.

(Buffer part 230)
The shock absorber 230 suppresses the generation of impact sound when the roller 220 collides with the inner wall surface of the hanger rail 110, and the friction coefficient is low in order to make the roller 220 travel smoothly in the hanger rail 110. Those are preferred. For example, urethane is used for the buffer portion 230, but is not limited thereto. As shown in FIG. 2, the buffer portion 230 includes a base portion 232 that is attached by fitting into the notch portion 222 of the roller 220 from above, and a protruding portion 234 that protrudes from the base portion 232 toward the outer periphery of the roller 220. Have. One end of the protrusion 234 is connected to the base 232 in a cantilevered state. A space 236 that is compressible and deformable in the radial direction of the roller 220 is formed between the base portion 232 and the protrusion portion 234 when the protrusion portion 234 is pushed in the direction of the base portion 232.

  As described above, the buffer portion 230 can be easily molded by adopting a structure in which one end of the protruding portion 234 is connected to the base portion 232 in a cantilever state. Further, when the roller 220 comes into contact with the inner wall surface of the hanger rail 110, the space between the protruding portion 234 and the base portion 232 is in a hollow state, so that the buffering effect can be improved.

  Here, the effect | action of the buffer part 230 is demonstrated, referring FIG.2 and FIG.3.

  When the runner 200 is traveling normally, such as when traveling on a straight portion of the hanger rail 110, the shock absorber 230 does not contact the shock absorber 114 as shown in FIG. There is no deformation of part 234.

  When the runner 200 collides with the cushioning material 114 on the inner wall surface 110c of the hanger rail 110, such as when the runner 200 travels at the intersection of the hanger rail 110, the cushioning portion 230 is as shown in FIG. Further, the protrusion 234 is pushed in the direction of the base 232 and deformed in the radial direction. As described above, when the roller 220 collides with the inner wall surface 110 c of the hanger rail 110, the protruding portion 234 is deformed in the radial direction, but the space 236 provides a hollow state between the protruding portion 234 and the base portion 232. Therefore, the buffer part 230 can improve the buffer effect.

  The suspension bolt 240 connects and suspends the upper end of the panel 120. As shown in FIG. 1, the suspension bolt 240 protrudes downward from the lower roller 220. Moreover, the suspension bolt 240 protrudes indoors from the opening of the lower part 110b of the hanger rail 110, and the upper end of the panel 120 is connected indoors.

  The configuration of the moving partition 100 according to the present embodiment has been described above. Next, operation | movement of the movement partition 100 of this embodiment is demonstrated, referring FIG.4 and FIG.5. 4 and 5 are views showing a state of the moving partition runner during traveling.

  In the moving partition 100 according to the present embodiment, the runner 200, as shown in FIG. 4A, is hanger rail when it is traveling normally, such as when it is traveling on a straight portion of the hanger rail 110. 110 does not contact the inner wall surface 110c of 110. Therefore, as shown in FIG. 2, the buffer portion 230 does not come into contact with the buffer material 114, so that the protruding portion 234 is not deformed.

  Then, as shown in FIG. 4B, the runner 200 collides with the inner wall surface 110 c of the hanger rail 110 when traveling on the intersection of the hanger rail 110. Therefore, as shown in FIG. 3, the buffer portion 230 is deformed in the radial direction when the protruding portion 234 is pushed in the direction of the base portion 232. However, since the space 236 is provided between the protrusion 234 and the base 232, the space between the protrusion 234 and the base 232 is hollow even if the protrusion 234 is deformed in the radial direction. Therefore, the buffer part 230 can improve the buffer effect.

  As shown in FIG. 5A, the runner 200 changes the traveling direction after colliding with the inner wall surface 110 c of the hanger rail 110 at the intersection of the hanger rail 110. Then, after the traveling direction is changed, the runner 200 moves in the changed traveling direction as shown in FIG. At this time, since the runner 200 is traveling on the straight portion of the hanger rail 110, as described above, the buffer portion 230 does not abut against the buffer material 114 as shown in FIG. There is no deformation.

(Effect of this embodiment)
As described above, according to the present embodiment, the buffer portion 230 is formed on the outer peripheral surface of the roller 220, and the buffer portion 230 is provided with the space 236 for compressive deformation in the radial direction. For this reason, even if the roller 220 collides with the inner wall surface 110c of the hanger rail 110 at the intersection of the hanger rail 110, generation of a large impact sound can be suppressed by a buffering effect due to the compression and deformation of the space 236.

  Further, in the present embodiment, the buffer material 114 is provided on the hanger rail 110, but by providing the shock absorber 230 with the buffer portion 230 on the runner 200, the hanger rail 110 side and the ground are not necessarily limited. There is no need to add a vibration device. Therefore, since existing hanger rails and bases can be adopted, the maintainability is improved, which is advantageous in terms of cost and the degree of freedom in design.

  Further, the buffer portion 230 has a protruding portion 234 protruding in the outer peripheral direction from a base portion 232 attached to the outer peripheral surface of the roller 220, and the protruding portion 234 can contact the inner wall surface 110 c of the hanger rail 110. For this reason, even if the roller 220 collides with the inner wall surface 110c of the hanger rail 110 at the intersection of the hanger rail 110, generation of a large impact sound is suppressed by the buffering effect of the protruding portion 234 that is deformed by compressive deformation of the space 236. Can do.

  In addition, by adopting a structure in which one end of the protruding portion 234 is connected to the base portion 232 in a cantilevered state, the buffer portion 230 can be easily molded, and when the inner surface 110c of the hanger rail 110 comes into contact with the base portion 232 Since the space between the protruding portion 234 and the base portion 232 is in a hollow state, the buffering effect can be improved.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, in the above embodiment, the buffer portion 230 is configured to protrude in the outer peripheral direction of the roller 220, but the present invention is not limited to this example. As the configuration of the buffer portion 230, an arbitrary configuration is adopted as long as a space for deformation when provided on the inner wall surface 110 c of the hanger rail 110 is provided even if it does not protrude in the outer peripheral direction of the roller 220. can do.

  In the above embodiment, the space 236 is compressed and deformed in the radial direction of the roller 220 in accordance with the deformation of the buffer portion 230, but the present invention is not limited to this example. The direction in which the space 236 is deformed is an appropriate direction such as the axial direction of the roller 220. In addition, since the volume of the space is reduced by the deformation of the buffer portion, the volume of the space may be changed although the shape of the space is changed.

  Moreover, in the said embodiment, although the buffer part 230 was set as the structure by which the end of the protrusion part 234 was connected with the base 232 in the cantilever state, this invention is not limited to this example. The buffer portion 230 can have an arbitrary shape such as a donut shape as long as a space is provided between the base portion 232 and the protruding portion 234.

  Moreover, although the said embodiment demonstrated the example which provided the buffer material 114 in the several location of the hanger rail 110, this invention is not limited to this example. For example, the position of the buffer material 114 provided on the hanger rail 110 can be designed as appropriate. Further, it is not always necessary to provide the buffer material 114 on the hanger rail 110.
