[0006] Problems to be solved by the invention

[0007] The separator described in Patent Document 1 is provided with a pair of casters at the lower end, so that it can smoothly switch from the storage rail to the rail side or the opposite side. However, since the casters can rotate freely around the vertical axis, there is a problem that the straightness is poor when connecting a plurality of separators in a straight line along the rail.

[0008] The present invention has been made in view of such problems, and an object of the present invention is to provide a partition that can smoothly change direction and has good straightness.

[0009] Means for solving problems

[0010] In order to solve the above-mentioned problems, the partition of the present invention is characterized in that a pair of guide units guided along a guide rail are provided at an upper end of a partition body, and wheels capable of running on the ground are provided at a center portion of a lower end.

[0011] According to this feature, the wheel is provided at the center of the lower end of the partition body and contacts the ground at one point, so that the direction of the partition can be changed smoothly.

[0012] The characteristic lies in that the wheel is a double wheel structure in which two wheel units are mounted on an axle.

[0013] According to this feature, the straightness of the separator is improved.

[0014] The feature is that the partition body has a frame-like frame, and the double wheels are provided at the center of the lower frame of the frame-like frame.

[0015] According to this feature, the weight of the partition body can be reduced, and the load applied to the ground via the wheels can be reduced, so that the direction of the partition can be changed more smoothly.

[0016] The invention is characterized in that the separation dimension between the two wheel units is slightly larger than the thickness of the spacer body, and the axle is located above the lower frame.

[0017] According to this feature, the lower frame of the spacer body can be inserted between the wheel units, and the axle is located above the lower frame, so the wheel units of the two wheels can be made larger in diameter to improve the drivability without changing the design of the spacer body.

[0018] The invention is characterized in that the two wheel monomers are pre-assembled with the axle and a mounting member of the axle to form a unit, and the entire double wheel including the axle is mounted on the upper surface of the lower frame via the mounting member.

[0019] According to this feature, the wheel can be easily installed or replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Hereinafter, the mode for implementing the separator of the present invention will be described based on Examples.

[0030] Example

[0031] Reference Figures 1 to 9 The separator of the embodiment is described. Figure 1 As shown, the partition 20 of this embodiment is used for the space structure 1, and the space structure 1 is also a movable partition device.

[0032] like Figure 1 As shown, the space structure 1 of this embodiment is independently installed on the ground F to divide a wide indoor space such as an office or exhibition hall into a square shape. The space structure 1 is used for a meeting or business space, etc.

[0033] The space structure 1 has a frame body 2 independently installed on the ground F. The frame body 2 has: 6 pillars 3, the 6 pillars 3 have a vertical dimension lower than the ceiling surface, and are arranged at predetermined intervals in the front, back, left, and right directions; and 7 beams 4 in the front, back, left, and right directions, and the 7 beams 4 connect the upper ends of the pillars 3 to each other at right angles in a "sun" shape when viewed from above. The pillars 3 and the beams 4 are made by extrusion molding of aluminum materials, for example.

[0034] like Figure 2 As shown in FIG. 1 , a guide rail 5 having a downward U-shaped cross section is fixed to the lower surface formed at the lower end of each beam 4 by means of a plurality of screws 6. The lower end of the guide rail 5 is bent inwardly opposite to each other. The guide rail 5 is made by extrusion molding of aluminum material, for example. In order to connect the bridge rail 13 described later, the length of the two guide rails 5 extending in the left-right direction in the front and the three guide rails 5 extending in the front-back direction are formed to be shorter than the total length of the beam 4 by a required dimension (see FIG. 1 ). Figure 3 , Figure 4 ). In addition, both side surfaces in the longitudinal direction of each beam 4 are covered by cover members 7, 7 together with both side surfaces of the guide rail 5, but such cover members 7 may be omitted.

[0035] like Figure 1 As shown in FIG. 1 , the partition 20 is supported movably by two guide rails 5 and 5 extending in the left-right direction in front of the support 3. Figure 2As shown, the lower ends of a pair of left and right support shafts 21a facing the up and down directions are fixed to the upper surface of the frame frame 21 of the partition 20, and the guide roller 10 serving as a guide unit which is horizontally rotatably installed on the upper ends of the two support shafts 21a can be rollably inserted into the guide rail 5, thereby supporting the partition 20 to be able to move along the guide rail 5.

[0036] Furthermore, a wheel 12 is installed at the center of the width direction of the lower surface of the frame frame 21 of the partition 20, and the wheel 12 rotates in contact with the ground F when moving. In this way, the partition 20 extends from the ground F to the upper guide rail 5, and the guide rollers 10 provided on the two support shafts 21a provided at the upper part are guided by the guide rail 5 and the wheels 12 provided at the lower part can roll on the ground F. Figure 1 Although only two separators 20 are shown in the figure, three or more separators 20 may be provided.

[0037] At the left corner of the front side of the frame body 2 ( Figure 1 At the terminal ends of the intersection direction of the guide rails 5, 5 of the A part), that is, at the terminal ends of the intersection direction of the adjacent guide rails 5, 5 installed on the two beams 4, 4 that are L-shaped from two directions and connected to the support 3 at right angles, both ends of a straight bridge rail 13 are laid in a manner that is 45 degrees when viewed from above and above and is continuous with the guide rails 5, 5, and the cross-sectional shape of the bridge rail 13 is the same as that of the guide rail 5. The upper surfaces of the two end portions of the bridge rail 13 are fixed to the lower surface of the beam 4 by means of screws 14. The lower ends of the adjacent cover parts 7, 7 are cut out to allow the bridge rail 13 to be inserted through. In addition, the same bridge rail 13 is also laid on the guide rail 5 of the right L-shaped intersection.

[0038] Furthermore, at the T-shaped intersection ( Figure 1 The terminals in the cross direction of the three guide rails 5 of part B), that is, the terminals in the cross direction of the three adjacent guide rails 5 installed on each beam 4 connected to the support 3 at right angles from three directions, are also provided with the same bridge rails 13, 13 as mentioned above at both ends in a manner that is 45 degrees when viewed from above and above and is continuous with the three guide rails 5.

[0039] like Figure 3 and Figure 4 As shown, since the bridge rails 13 are laid on the guide rails 5 at the L-shaped intersection and the T-shaped intersection of the beam 4, the partition 20 can be moved from the beam 4 facing the left and right direction to the side of the beam 4 facing the front and rear direction via the bridge rails 13, bypassing the support 3. As a result, the partition 20 is changed from the front to the rear, and the plate-shaped functional component described later can be used.

[0040] And, if Figure 5 As shown, when the right partition 20 is moved to Figure 1When the T-intersection side of portion B is temporarily moved to the guide rail 5 extending in the front-to-back direction via the right bridge rail 13 and then turned back to the guide rail 5 on the opposite side via the left bridge rail 13, the partition 20 can be rotated 180 degrees to reverse the front and back sides, so that both sides of the plate-like functional component can be used.

[0041] Next, the structure of the partition 20 is described in detail. The partition 20 mainly includes: a frame 21; a felt screen (plate-shaped functional component) 11, which is arranged at the upper part of the frame 21 and is roughly rectangular when viewed from the front; and a panel 52, which is arranged at the lower part of the frame 21. A pair of guide rollers 10, 10 as guide units, which are separated in the width direction and arranged at the upper end of the frame 21, can move along the guide rail 5, and the load of the partition 20 is supported by the ground F by means of wheels 12 arranged at the center of the width direction of the lower end of the frame 21. The wheels 12 rotate in contact with the ground F when the partition 20 moves. The frame 21 and the felt screen (plate-shaped functional component) 11, which is roughly rectangular when viewed from the front and is arranged in the frame 21, constitute the partition body 30.

[0042] like Figure 6 to Figure 9 As shown, the wheel 12 is a double wheel structure in which two wheel monomers 120a, 120a are mounted on both ends of the axle 31 facing in a direction perpendicular to the moving direction of the partition body 30 (the thickness direction of the partition body 30), and the wheel 12 is mounted on the upper surface plate-like portion 122b (details will be described later) of the transverse frame portion 22b connecting the lower portions of the longitudinal frame portions 22a, 22a of the frame frame 21 by means of a mounting member 32. The wheel monomer 120a is formed of a relatively large diameter, for example, a light metal such as synthetic resin or aluminum, and is reinforced by protruding a plurality of ribs on both side surfaces.

[0043] The wheel 12 is pre-assembled as follows. Figure 6 to Figure 9 First, an axle 31 having an enlarged diameter portion at one end is inserted from the outside into a stepped hole 120b at the center of a wheel unit 120a on one side, and the middle portion of the axle 31 is supported so as to be rotatable via a bearing (rolling bearing) 33 engaged with a mounting component 32 and a pair of cylindrical spacers 34, 34 on both sides thereof.

[0044] Next, the other end of the axle 31 is inserted into the stepped hole 120b of the other wheel unit 120a, and the screw 35 with a washer is screwed into the internal threaded hole formed on the end surface of the axle 31 (not shown). Thus, the two wheel units 120a, 120a, the axle 31, the mounting member 32 and the pair of spacers 34 are assembled and unitized. The wheel units 120a, 120a rotate integrally with the axle 31. In addition, the wheel units 120a, 120a are assembled in such a way that their separation dimension is slightly larger than the thickness of the spacer body 30 (the axial dimension of the axle 31).

[0045] like Figure 8 As shown, screws 39, 39 with hexagonal holes inserted from above into mounting holes formed by a pair of fixing portions 32a, 32a of the mounting component 32 are screwed into internal threaded holes formed in the central portion in the width direction of the upper surface plate-like portion 122b of the transverse frame portion 22b (not shown in the figure), whereby the wheel 12 is detachably fixed to the upper surface of the central portion of the transverse frame portion 22b in a manner in which its axle 31 is located above the transverse frame portion 22b.

[0046] As described above, in the partition 20 of the embodiment, the wheel 12 is provided at the center of the lower end of the partition body 30 and contacts the ground F at one point, so that the partition 20 can move smoothly when changing direction.

[0047] In particular, when the partition 20 is moved from the beam 4 facing the left-right direction to the beam 4 facing the front-back direction via the bridge rail 13, the guide rail 5 of the beam 4 and the bridge rail 13 extend in a direction different from the moving direction of the partition 20, and the wheel 12 is in sliding contact with the ground F. Therefore, by adopting a structure that contacts the ground F at one point, the friction resistance can be reduced and the direction change can be smoothly performed. In addition, even when the partition 20 is moved to reverse 180 degrees, the friction resistance can be reduced and the reverse operation can be smoothly performed.

[0048] Furthermore, since the wheels 12 are double-wheel structures, the straightness of the partitions 20 when they are moved along the guide rails 5 and the bridge rails 13 is good, and a plurality of partitions 20 can be aligned and connected in a straight line.

[0049] In addition, since the partition body 30 has a hollow frame frame 21, and the wheel 12 is provided in the central part of the lower horizontal frame part 22b of the frame frame 21, the partition body 30 can be made lightweight and the load applied to the ground F through the wheel 12 can be reduced, so that the direction change of the partition 20 can be carried out more smoothly.

[0050] In addition, since the separation size of the wheel units 120a, 120a is slightly larger than the thickness of the partition body 30, and the axle 31 is located above the transverse frame portion 22b, the wheel units 120a, 120a will not interfere with the lower end of the partition body 30. Therefore, the wheel unit 120a can be made into a larger diameter without changing the design of the partition body 30, thereby improving the driving performance.

[0051] In addition, since the wheel 12 is unitized by pre-assembling the two wheel units 120a, the axle 31, the mounting components 32 of the axle 31, and a pair of spacers 34, and the wheel 12 including the axle 31 is mounted as a whole on the upper surface plate portion 122b of the transverse frame portion 22b with the aid of the mounting components 32, the wheel 12 can be easily installed and replaced.

[0052] And, if Fig. 9 As shown, the lower end of the panel 52 disposed at the lower part of the frame 21 is inserted into the upper half between the wheel monomers 120a, 120a, so that the wheel 12 and the panel 52 can be shown as a sense of unity in appearance, and the large-diameter wheel 12 can also function as a space division structure. In addition, it is not easy for hands and feet to enter between the wheel 12 and the panel 52, and it can prevent them from being pinched and injured.

[0053] Furthermore, the diameter of the wheel 12 is sufficiently larger than the height dimension of the lateral frame portion 22 b , and specifically, is three times or more in length. Thus, the spacer 20 can be stably driven using only one wheel 12 .

[0054] Furthermore, the wheel 12 has a large diameter, specifically, a diameter that is sufficiently longer than 1 / 10 of the length dimension of the lateral frame portion 22 b . Thus, the spacer 20 can be stably driven using only one wheel 12 .

[0055] As mentioned above, although the embodiment of the present invention is described based on the drawings, the specific structure is not limited to these embodiments, and additions and changes within the scope that does not depart from the gist of the present invention are also included in the present invention.

[0056] For example, in the above-mentioned embodiment, the wheel 12 adopts a double wheel structure, but sometimes a single wheel is adopted. In this case, it is sufficient to set the single wheel on the transverse frame portion 22b.

[0057] Furthermore, in the aforementioned embodiment, the middle portion of the axle 31 is supported by the bearing 33 , but for a lightweight partition 20 with relatively small vertical dimensions, the bearing 33 may be omitted and the middle portion of the axle 31 may be directly rotatably supported by the mounting member 32 .

[0058] In the above-described embodiment, the wheel units 120a, 120a of the wheel 12 rotate integrally with the axle 31, but the two wheel units 120a may be rotatably supported at both ends of the axle 31 via bearings (or without bearings).
