It is possible to cope with some cases, and smooth movement becomes possible.

FIGS. 1B and 4A show a standard state in which the height dimension from the floor 4 to the ceiling 2 where the partition panel 1 is installed is a standard dimension (for example, a desirable dimension). In this state, it arrange | positions so that the upper end surface of the panel main body 10 and the lower surface of the lower guide pieces 53 and 53 of the upper rail 50 may face each other with a moderate space | interval. In addition, the projecting dimension of the vertical shaft 28 from the spring case 31 is approximately the middle between the maximum projecting dimension and the minimum projecting dimension.
FIG. 4B shows a state in which the height from the floor 4 to the ceiling 2 is larger than the standard state. In this state, the upper end surface of the panel main body 10 and the lower guide pieces 53, 53 of the upper rail 50 are arranged so as to face each other with a larger interval than the standard state. Further, the projecting dimension of the vertical shaft 28 from the spring case 31 is a projecting dimension larger than that of the standard state, and is relatively close to the maximum projecting dimension.
FIG. 4C illustrates a state where the height dimension from the floor 4 to the ceiling 2 is smaller than the standard state. In this state, the upper end surface of the panel body 10 and the lower guide pieces 53, 53 of the upper rail 50 are disposed so as to face each other with a smaller interval than the standard state. In addition, the projecting dimension of the vertical shaft 28 from the spring case 31 is a projecting dimension smaller than that in the standard state, and is relatively close to the minimum projecting dimension.

In any of the above cases, the roller portion 21 is biased upward by the upward biasing of the vertical shaft 28 by the compression coil spring 30. Therefore, even when there is a difference in height from the floor 4 to the ceiling 2 due to unevenness or the like, it is possible to prevent the roller portion 21 having the upper end rollers 24, 24 from being detached from the upper rail 50. The upper end rollers 24, 24 can be brought into contact with the top wall portion 51 of the upper rail 50.
Further, when the partition panel 1 is moved, the upper end rollers 24 and 24 are brought into contact with the top wall 51 and rotate around the horizontal shaft 23. Therefore, although it is biased upward and is pressed against the top wall 51 of the upper rail 50, the frictional resistance between the top wall 51 and the upper guide 20 is extremely small, and smooth movement is possible. It becomes.

In the present embodiment, a plurality of upper end rollers 24, 24 are provided at intervals in the direction along the width direction of the upper rail 50. Therefore, when the partition panel 1 is moved, the plurality of upper end rollers 24, 24 rotate in a pressed state against the top wall portion 51 of the upper rail 50, so that the partition panel 1 is more stable. And it can be moved smoothly.
Further, in the present embodiment, upper end rollers 24 and 24 are provided on the movement direction regulating block 22. Therefore, when the partition panel 1 moves along the panel width direction, the movement of the movement direction restriction block 22 around the vertical axis 28 is suppressed by the restriction by the side walls 52, 52 of the upper rail 50. Is done. As a result, the skew of the upper end rollers 24, 24 arranged in the movement direction regulating block 22 is suppressed, and a smoother movement is possible.
On the other hand, when the direction of the partition panel 1 is changed, the movement direction restriction block 22 is rotatable about the vertical axis 28 with respect to the partition panel 1. Therefore, when the movement direction regulating block 22 is rotated around the vertical axis 28, the traveling direction of the upper end rollers 24, 24 is changed, and smooth movement becomes possible. In addition, the rotation aspect of the movement direction restricting block 22 around the vertical axis 28 will be described later.

Furthermore, in this embodiment, the compression coil spring 30 as the urging member is connected to the lower end side of the vertical shaft 28, and the upper guide portion 20 is provided with the spring case 31 and the fixing bracket 33 configured as described above. Yes. In other words, the compression coil spring 30 that urges the upper end rollers 24, 24 upward is connected to the lower end side of the vertical shaft 28 that is fixedly connected to the movement direction restricting block 22. Therefore, even when a plurality of upper end rollers 24, 24 are provided as in the present embodiment, it is not necessary to provide an urging member individually, and a simple structure can be achieved. Further, the vertical shaft 28 can be guided in the vertical direction by the spring case 31, and the vertical shaft 28 can be held unrotatable, so that the structure can be simplified.
Further, by making the spring case 31 that accommodates the compression coil spring 30 rotatable about the vertical axis 28 with respect to the partition panel 1, for example, one end of the urging member is fixedly connected to the partition panel side. Compared with such a thing, deterioration of an urging member, generation | occurrence | production of unusual noise, etc. can be suppressed.

In the present embodiment, the upper guide portion 20 is provided with rollers 25 and 26 that are rotatable around the vertical axis 28. Accordingly, when the partition panel 1 is moved, the rollers 25 and 26 are in contact with the side wall portion 52 of the upper rail 50 and rotate, so that the guide on the upper end portion 12 side of the partition panel 1 is smoothly performed. The
In the present embodiment, these rollers 25 and 26 are provided adjacent to the movement direction restricting block 22 along the direction of the vertical axis 28. Therefore, while being able to guide smoothly, the moving direction regulating block 22 and the rollers 25 and 26 on the lower side thereof are uniaxially provided to achieve a compact size.

By the way, when moving the partition panel 1 in this way, if the partition panel 1 is maintained in a state perpendicular to the ceiling 2 and the floor 4, the rollers 25 and 26 of the roller portion 21 are connected to the upper rail 50. In contact with one side wall 52 and rotate in the same direction. The partition panel 1 is not provided with a guide for a caster section 40 to be described later on the floor 4 side, and the caster section 40 is rotatable about a vertical line with respect to the partition panel 1. Therefore, it is conceivable that when the partition panel 1 is moved, downward deflection (inclination) in which the lower end portion 14 side swings in the thickness direction is likely to occur.
According to the partition panel 1 according to the present embodiment, as described below, it is possible to smoothly move while reducing such downward deflection.

  In other words, the outer peripheral surfaces of the rollers 25 and 26 of the upper guide portion 20 are structured so as to face each other on both side walls 52 and 52 of the upper rail 50 with a slight clearance therebetween. It is regulated by 50 side walls 52, 52. Thereby, the downward runout of the partition panel 1 can be reduced. Further, for example, in the case where the upper guide portion provided with a single roller is used, if a slight downward deflection occurs in the partition panel, each of the outer peripheral upper edge portion and the outer peripheral lower edge portion of the roller is the upper rail 50. It is conceivable that the side walls 52, 52 on the different sides of the two abut against each other. If the partition panel is moved in such a state, the direction in which one of the contact points tries to rotate is different from the direction in which the other contact point tries to rotate, and frictional resistance (rotational resistance) and Thus, smooth movement will be hindered. According to the present embodiment, such frictional resistance can be remarkably reduced. In other words, even when the partition panel 1 is inclined, the rollers 25 and 26 separated vertically are brought into contact with the different side wall portions 52 and 52 of the upper rail 50 and rotate in different directions. Thus, the frictional resistance can be relieved dramatically, and smooth movement becomes possible.

Next, specific configurations of the caster unit 40 and the connecting member 35 will be described.

In the present embodiment, as shown in FIGS. 4 and 5, a plurality of rolling wheels 49 are provided to be rotatable around the horizontal axis 48 along the axial direction of the horizontal axis 48. In the illustrated example, two rolling wheels 49 are provided. The example which provided the driving wheels 49 and 49 in the horizontal axis | shaft 48 so that the bearing part 47 may be pinched | interposed is shown. In the present embodiment, the axis of the horizontal shaft 48 and the axis of the vertical shaft 43 of the caster portion 40 are provided so as to substantially coincide with each other in the perpendicular direction.

Further, a bearing mounting portion 45 is fixedly provided on the upper surface side of the rolling wheel bracket 46. The bearing mounting portion 45 is provided with a bearing portion 44 through which the vertical shaft 43 is inserted and rotatably supports the vertical shaft 43. In the present embodiment, the bearing portion 44 is a thrust ball bearing. As a result, the rolling wheel bracket 46 smoothly rotates with respect to the fixed bracket 41 around the vertical shaft 43 fixedly connected to the rolling wheel bracket 46 or the bearing mounting portion 45.
With such a configuration, the vertical shaft 43 and the rolling wheel bracket 46 are rotatable around the vertical shaft 43 with respect to the fixed bracket 41, that is, the partition panel 1.

  As shown in FIGS. 1A and 5, the upper connecting member 36 has a substantially cylindrical shape that opens up and down, receives the lower part of the spring case 31 of the upper guide portion 20 from the upper opening, The upper end portion of the connecting rod 37 is received from the side opening. An engagement surface that engages with the connection engagement surface 31 a of the spring case 31 of the upper guide portion 20 is formed on the inner peripheral surface on the upper end side of the upper connection member 36. The upper connecting member 36 and the spring case 31 and the connecting rod 37 are fixedly connected. With such a configuration, when the connecting member 35 is rotated around the vertical shaft 28, the spring case 31 of the upper guide portion 20, the vertical shaft 28 that is held unrotatable by the spring case 31, and the vertical shaft 28 are fixed. The movement direction restricting block 22 provided for the purpose rotates around the vertical axis 28.

  The lower connecting member 39 is shaped like the upper connecting member 36 turned upside down, and has a substantially cylindrical shape that opens up and down as described above. The lower connecting member 39 receives the lower end of the connecting rod 37 from the upper opening, The vertical shaft 43 of the caster part 40 is received from the side opening. An engagement surface that engages with the connection engagement surface 43 a of the vertical shaft 43 of the caster portion 40 is formed on the inner peripheral surface on the lower end side of the lower connection member 39. The lower connecting member 39, the connecting rod 37, and the vertical shaft 43 of the caster part 40 are fixedly connected. With such a configuration, when the connecting member 35 is rotated about the vertical shaft 43, the rolling wheel bracket 46 fixedly connected to the vertical shaft 43 of the caster portion 40 rotates about the vertical shaft 43.

In the present embodiment, the connecting rod 37 has a prismatic shape. As shown in FIG. 5, the connecting rod 37 is exposed to the surface side of the partition panel 1 at a midway position in the longitudinal direction. Is fixedly provided (see also FIG. 1A). By operating this operation portion 38, the connecting rod 37 rotates about the vertical axes 28 and 43 with respect to the partition panel 1, and both the vertical shafts 28 and 43 of the upper guide portion 20 and the caster portion 40 are moved. It rotates around the axis with respect to the partition panel 1.
As shown in FIGS. 5 to 7, notches 13 that receive the operation unit 38 and allow the operation unit 38 to rotate are provided at both ends in the panel width direction of the panel body 10.
Further, as shown in FIG. 1A, a connecting member 35 provided along the side end surface 11, a spring case 31 of the upper guide portion 20, a fixing bracket 33, and casters are provided at both side ends of the panel body 10. End covers 15 and 15 are attached to cover the fixing bracket 41 of the portion 40. In addition, operation unit covers 16 and 16 are attached to portions of the panel body 10 where the operation units 38 and 38 are provided at both end portions so as to surround the operation units 38 and 38.

  The partition panel 1 having the interlocking mechanisms 22 and 35 as described above is arranged so that the moving direction of the upper guide portion 20 and the traveling direction of the rolling wheels 49 of the caster portion 40 are in the same direction as described below. The traveling direction of the rolling wheels 49 of the caster unit 40 is regulated in conjunction with the guide unit 20.

FIG. 5 shows a state in which the partition panel 1 is moved in the direction along the panel width direction, and the moving direction of the upper guide portion 20 is the direction along the panel width direction. That is, as shown in the present embodiment, the one provided with the upper end roller 24 that rotates around the horizontal axis 23 shows a state in which the traveling direction of the upper end roller 24 is a direction along the panel width direction.
In this state, the traveling direction of the rolling wheels 49 and 49 of the caster part 40 connected to the upper guide part 20 via the connecting member 35 is also restricted in the direction along the panel width direction.
That is, when the partition panel 1 moves along the panel width direction, both side surfaces 22a and 22a of the movement direction restricting block 22 are regulated by the both side walls 52 and 52 of the upper rail 50, and the upper end roller 24 is moved. The traveling direction is maintained in a direction along the panel width direction. This also suppresses the rotation of the vertical shaft 28 of the upper guide portion 20, and suppresses the rotation of the vertical shaft 43 of the caster portion 40 connected to the vertical shaft 28 via the connecting member 35. 49 and 49 are maintained so that the traveling direction is the direction along the panel width direction.
As a result, when the partition panel 1 is moved in the direction along the panel width direction, the rolling wheels 49 and 49 of the caster portion 40 are difficult to skew, and the downward swing of the partition panel 1 can be suppressed and smooth. It can be moved.

In FIG. 6, the operation portion 38 of the connecting member 35 is rotated, and the moving direction of the upper guide portion 20 provided at one side end portion (left end portion in the illustrated example) of the partition panel 1 is changed to the partition panel. 1 shows a state in which it is in a diagonally rearward direction with respect to the panel width direction of 1.
On the other hand, in FIG. 7, the operation portion 38 of the connecting member 35 is rotated to change the movement direction of the upper guide portion 20 provided at the left end portion of the partition panel 1 with respect to the panel width direction of the partition panel 1. In this state, the front side direction is shown.
In any of these cases, by rotating the operation portion 38, the movement direction regulating block 22 of the upper guide portion 20 is rotated around the vertical axis 28, and the traveling direction of the upper end roller 24 is a desired direction (obliquely). The rear side direction and the front side direction are changed and maintained. Further, in conjunction with the upper guide portion 20, the traveling direction of the rolling wheels 49, 49 of the caster portion 40 is desired to be in the same direction as the moving direction of the upper guide portion 20 (oblique rear side direction, diagonal direction). It is changed and maintained so as to be in the front side direction).

According to the partition panel 1 provided with such interlocking mechanisms 22 and 35, as shown in FIG. 8, when the direction of the partition panel 1 is changed at a portion (corner portion) where the cross member 7 is provided. Smooth movement is possible. That is, the upper guide portion 20 on the front side in the moving direction is moved along the upper rail 50 and the crossing member 7 while turning the operating portion 38 provided at the front end portion in the moving direction. As a result, the traveling direction of the rolling wheels 49 of the caster part 40 is also changed smoothly in conjunction with the upper guide part 20. Further, when the upper guide portion 20 on the rear side in the moving direction reaches the portion where the crossing member 7 is provided, the operating portion 38 provided on the rear end portion in the moving direction is rotated and operated in the same manner as described above. The upper guide portion 20 on the side is moved so as to curve along the upper rail 50 and the cross member 7. Thereby, similarly to the above, the traveling direction of the rolling wheels 49, 49 of the caster part 40 is also changed smoothly in conjunction with the upper guide part 20.
That is, the rolling wheels 49 and 49 of the caster part 40 travel so as to draw a curve in the corner part in conjunction with the movement of the upper guide part 20, and the partition panel 1 can be smoothly turned.

In addition, when changing the direction of the partition panel 1 in the part provided with the corner member 6 or the part provided with the T-shaped member, the direction change can be performed in the same manner as described above.
In the illustrated example, two upper rails 50 are arranged in parallel, and a total of eight upper rails 50 are joined at a portion where the cross member 7 is provided. When the direction is changed at the portion where the cross member 7 is provided, the upper guide portion 20 may be operated so as to move toward the desired upper rail 50 via the cross member 7. .

According to the partition panel 1 according to the present embodiment, as described above, since the caster part 40 that is allowed to run on the floor 4 is provided on the lower end part 14 side, the load of the partition panel 1 is transferred to the caster part 40. Can be received at. Therefore, the necessity of firmly fixing the upper rail 50 to the ceiling 2 side is reduced, and the necessity of providing a mounting base on the ceiling 2 side or performing a reinforcement work is reduced. For example, the partition panel 1 The upper rail 50 for guiding the upper end portion 12 side can also be installed directly on the ceiling 2.
Moreover, since the lower end part 14 side is made to run on the floor 4 by the caster part 40, there is no need to lay a guide rail or the like on the floor 4 side, a step or the like is not formed on the floor surface, and the installation target is simplified. It can be a simple structure. Further, the direction of the partition panel 1 can be changed relatively easily.

  Furthermore, in this embodiment, the interlocking mechanism includes a restricting portion (moving direction restricting block) 22 fixedly connected to the vertical shaft 28 of the upper guide portion 20, and the vertical shaft 28 and the caster portion 40 of the upper guide portion 20. The structure includes a connecting member 35 that connects the vertical shaft 43. Therefore, the vertical shaft 28 of the upper guide portion 20 is restricted by the movement direction restricting block 22 from being restricted by the side walls 52 and 52 of the upper rail 20, and is connected via the connecting member 35. The rotation of the vertical shaft 43 of the caster unit 40 is regulated in conjunction with it. Thereby, the rotation of the caster unit 40 around the vertical axis 43 and the rotation of the upper guide unit 20 around the vertical axis 28 can be linked with a simple structure, and the caster unit 40 is linked with the upper guide unit 20. The interlocking mechanism that regulates the traveling direction of the rolling wheels 49, 49 can be a simple structure.

Furthermore, in the present embodiment, the axis of the horizontal shaft 48 of the rolling wheels 49 and 49 of the caster unit 40 and the axis of the vertical shaft 43 of the caster unit 40 are provided so as to substantially coincide with each other in the perpendicular direction. . Therefore, when the direction of the partition panel 1 is changed, the vertical shaft 43 of the caster portion 40 rotated in conjunction with the vertical shaft 28 of the upper guide portion 20 can be rotated relatively smoothly and with good responsiveness. it can. Instead of such an embodiment, the axis of the vertical shaft 43 of the caster part 40 and the axis of the horizontal shaft 48 of the rolling wheels 49, 49 may be provided eccentrically.
Moreover, in this embodiment, it is set as the double-wheel structure which provided the two rolling wheels 49 and 49 in the caster part 40 at intervals in the horizontal axis 48 direction. Therefore, the stability of the partition panel 1 when moving can be improved, and the rolling wheel bracket 46 can be rotated more smoothly around the vertical shaft 43.

  Further, in the present embodiment, the interlocking mechanisms 22 and 35 are provided so as to be exposed to the surface side of the partition panel 1 at a midway position of the connecting member 35, and both vertical axes of the upper guide portion 20 and the caster portion 40 are provided. An operation unit 38 for rotating the shafts 28 and 43 around the shaft is provided. Therefore, by operating the operation unit 38, the upper guide unit 20 and the caster unit 40 can be rotated in a desired direction via the connecting member 35. In addition, it is good also as an aspect which does not provide such an operation part 38. FIG. In this case, the movement direction is changed so that the movement direction restriction block 22 of the upper guide part 20 draws a curve under the restriction of the both side walls 52, 52 of the upper rail 50, that is, the vertical shaft 28 is rotated. As may be done, guides may be provided at the corners of the upper rail 50. In other words, instead of a mode in which the vertical shaft 28 of the upper guide portion 20 is rotated by manual operation, a mode in which the upper guide portion 20 is rotated around the vertical shaft 28 by a guide action by the upper rail 50 may be employed.

  Further, in the present embodiment, the upper guide portion 20, the interlocking mechanisms 22 and 35, and the caster portion 40 are provided at each of both end portions in the width direction of the partition panel 1. Therefore, the partition panel 1 can be moved stably. Moreover, the operability at the time of changing the direction of the partition panel 1 can be improved comparatively by providing these in each of the width direction both ends which are the moving direction front side and the moving direction rear side.

  Further, in the present embodiment, the roller portion 21 of the upper guide portion 20 is configured to be movable in the vertical direction with respect to the partition panel 1 and urged upward. Absent. For example, instead of an aspect in which the roller portion 21 is urged upward, an aspect in which the roller portion 21 is urged downward may be employed, or the roller section 21 may be simply movable in the vertical direction. Further, instead of such a mode, the roller unit 21 may be configured to be immovable in the vertical direction. In this case, the connecting member 35 may be directly connected to the vertical shaft 28 of the upper guide portion 20. In this case, the clearance between the top wall portion 51 or the lower guide piece 53 of the upper rail 50 and the roller portion 21 may be made relatively large. Furthermore, the top wall portion 51 or the lower guide The piece 53 may not be provided on the upper rail 50.

However, it is not limited to such a mode. For example, it is good also as a structure which provided the bearing part etc. of each roller in the vertical axis | shaft 28 (roller axial part 29) so that adjacent rollers may not contact | abut.
Further, in the present embodiment, an example in which these rollers 25 and 26 are provided on the lower side of the movement direction restriction block 22 is shown, but the rollers 25 and 26 may be provided on the upper side of the movement direction restriction block 22. You may make it provide in each of 22 upper and lower sides. In this case, the upper end roller 24 may be omitted as described above.
