[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] FIG. 1 illustrates a partition device in which two partition panels 1 are suspended from a ceiling rail R fixed to a ceiling T.

[0016] In Figures 1 to 7, 11 and 12, a single partition panel 1 has an upper crosspiece 4 and a lower crosspiece 5 attached to the upper and lower edges of a rectangular panel face 3, upper connectors 6 fixed to both left and right ends of the upper crosspiece 4, and lower connectors 7 fixed to both left and right ends of the lower crosspiece 5, with the left and right upper connectors 6 and lower connectors 7 connected by support members 8.

[0017] The panel surface 3 is generally made of a plastic plate such as polycarbonate or acrylic resin, but it can also be made of woven fabric, wood board, or paper board, and can be transparent, colored, or patterned.Border members (frames) are fixed to the top, bottom, left, and right edges, and the panel surface 3 is formed into a rectangular shape such as a rectangle or square.

[0018] The upper and lower crosspieces 4 and 5 are formed of channeled materials with a longitudinal groove j that is symmetrical from top to bottom. Channeled materials are made by extrusion or drawing of aluminum alloy, and may also be made of synthetic resin.

[0019] As shown in Figs. 2, 5, and 12, the upper and lower crosspieces 4 and 5 are connected to the front and rear walls a and b and the center in the vertical direction. The front wall a has an intermediate wall c between the front and rear ends, a front flange d extending rearward from the upper and lower ends of the front wall a, and a rear flange e extending forward from the upper and lower ends of the rear wall b, and a longitudinal groove j, j is formed by the front and rear walls a, b and the intermediate wall c. The groove width of this groove j, j narrows between the front flange d and the rear flange e and opens outward.

[0020] The upper crosspiece 4 is attached by fitting its lower groove j into the upper edge material of the panel face body 3, and a lifting runner 9 is detachably mounted on the upper surface of the upper crosspiece 4 using the groove j. A circular hole n (Fig. 12) is formed in the groove j on the upper surface of the upper crosspiece 4, approximately in the center in the longitudinal direction, so that the lower end of the connector 17 of the lifting runner 9 can enter.

[0021] 11, upper connectors 6 made of resin or metal are fixed to both the left and right ends of the upper crosspiece 4, and these upper connectors 6 have the same shape on the left and right, and each upper connector 6 has an insertion connecting portion 6a protruding in the left-right direction from a main body portion that is roughly rectangular when viewed from the front, and this insertion connecting portion 6a is inserted into a groove j of the upper connector 6 and fixed with a screw. The insertion connecting portion 6a is shaped to fit into the grooves j on both the upper and lower levels or into the groove j on either the upper or lower level.

[0022] A circular upper recess 6b is formed on the upper surface of the main body of the upper connecting body 6, and a buffer member 20 is provided on the upper surface of this upper recess 6b. This buffer member 20 prevents the upper connecting body 6 from directly colliding with the ceiling T when the partition panel 1 swings up and down around the suspension runner 9, thereby buffering the impact.

[0023] The lower surface of the main body of the upper connecting body 6 is formed with a lower recess 6c for connecting and fixing the core rod 21 of the support member 8.

[0024] The lower cross-sectional shape of the upper cross-section of the lower cross-section of the upper cross-section of the panel face 3 is approximately the same as that of the upper cross-section of the panel face 3, and two grooves j, j are formed on either side of the intermediate wall c, with the upper groove j being fitted into and attached to the lower edge of the panel face 3.

[0025] The lower connectors 7 fixed to both the left and right ends of the lower crosspiece 5 have approximately the same shape, and are also the same shape as the upper connectors 6. Each lower connector 7 has an insertion connector 6a protruding in the left-right direction from a main body that is approximately rectangular when viewed from the front, and this insertion connector 6a is inserted into a groove j of the upper connector 6 and fixed with a screw. The insertion connector 6a is shaped to fit into the grooves j on both the upper and lower levels, or into the groove j on either the upper or lower level.

[0026] An upper recess 7c is formed on the upper surface of the main body of the lower connecting body 7 to connect and fix the core rod 21 of the support member 8. A lower recess is formed on the lower surface of the main body of this lower connecting body 7, and an upper connecting body 6 of the same shape is used by being inverted upside down or left to right.

[0027] In Figures 1, 3 to 5, 8 to 10, the left and right support members 8 have a core rod 21 whose upper and lower ends are inserted and connected to the lower recess 6c of the upper connecting body 6 and the upper recess 7c of the lower connecting body 7, an outer tube 22 fitted to this core rod 21 so as to be rotatable around its vertical axis, and a joining member 23 and a joined member 24 arranged above and below this outer tube 22.

[0028] The workpiece 24 has an arc-shaped outer peripheral surface 24a that is approximately concentric with the core rod 21 and a flat outer surface 24b that protrudes from the side of the combined body, and an iron plate F is embedded in this flat outer surface 24b. The workpiece 24 can rotate approximately 180 degrees around the core rod 21 without coming into contact with the panel surface body 3.

[0029] The joining member 23 has an arcuate outer surface 23a that is approximately concentric with the core rod 21 and a flat outer surface 23b that protrudes from the side of the joining body, and has a magnet M embedded in it whose legs that are magnetically attached to the iron plate F protrude from the flat outer surface 24b.

[0030] The joining member 23 has an upper and lower portion that fits onto the core rod 21, with the portion in between being a hollow body, with a magnet M embedded in the space behind the flat outer surface 23b and a filler member 27 arranged to back the magnet M. The filler member 27 is fitted onto the core rod 21, and the magnet M has iron plates attached to both the left and right sides of the ferrite magnet, with legs formed on the iron plates that protrude from the flat outer surface 24b.

[0031] There is a weight difference between the joining member 23 and the member to be joined 24, and in order to prevent a weight difference between the left and right parts of the partition panel 1 and to improve the left and right weight balance, the joining member 23 is placed above one of the left and right support members 8 and below the other, and the member to be joined 24 is placed below one of the left and right support members 8 and above the other.

[0032] A convex portion 36 is formed above or below the magnet M on the flat outer surface 23b of the joining member 23, A recessed rib portion 37 that fits into the protruding rib portion 36 is formed above or below the iron plate F on the flat outer surface 24b of the workpiece 24, and when the recessed rib portion 37 fits into the protruding rib portion 36, the joining workpiece 23 and the workpiece 24 become approximately the same height and can be magnetically attached.

[0033] 1 to 7, the lifting runner 9 has two wheels 13 in the running direction that are placed rollably on the ceiling rail R, a support 15 that supports the two wheels 13 via axles 14, a support base 16 that is detachably fixed to the top surface of the upper crosspiece 4, and a connector 17 that penetrates and connects the support base 16 to the support 15 placed on top of it. The wheels 13 are of the double wheel type that sandwich the support 15, making a total of four wheels, including the two in the running direction. The wheel 13 may be of the double wheel type or one in the running direction.

[0034] The connecting device 17 has a vertical shaft 18 whose upper part is connected to the support body 15 so as to be able to rotate relatively around the vertical axis, and the lower part of this vertical shaft 18 is provided with an elastic member (coil spring) 19 which penetrates the support base 16 and resiliently biases the support base 16 toward the support body 15.

[0035] The support base 16 is roughly trapezoidal when viewed from the front, with a hole 16b formed in the center of the upper wall 16a through which the vertical axis 18 passes, fastening bolts 33 that enter grooves j are arranged on the left and right sides, and a nut 34 is threaded onto the bottom of the bolt 33 inserted into the groove j.

[0036] The support base 16 is placed on the upper surface of the upper crosspiece 4, and when the bolt 33 is rotated, the wraparound nut 34 rotates integrally on the underside of the front flange d and the rear flange e and stops when it abuts against the front and rear walls a, b. When the bolt 33 is next rotated, the wraparound nut 34 is lifted and abuts against the underside of the front flange d and the rear flange e and is tightened.

[0037] Therefore, the support base 16 is removably fixed to the top surface of the upper crosspiece 4 using the groove j, bolts 33, and wraparound nuts 34. In the fixed state, the vertical shaft 18 passes through the circular hole n of the groove j of the upper crosspiece 4, allowing the vertical shaft 18 to move up and down and shortening the distance from the upper crosspiece 4 to the wheel 13.

[0038] The lifting runner 9 has a support 15 with wheels 13 and a support base 16 fixed to the upper surface of the upper crosspiece 4, which can rotate around a connecting device 17, allowing the upper crosspiece 4 to swing (tilt) up and down via an elastic member 19.

[0039] The ceiling rails R fixed to the ceiling T come in various shapes, such as straight or curved, but the partition panel 1 is suspended by the suspension runners 9 and can therefore swing and rotate in all directions around the suspension runners 9, allowing it to run no matter how curved the ceiling rail R is, and even if multiple panels are connected together.

[0040] 13 is a plan view showing the bent arrangement of a partition device equipped with three partition panels 1. The ceiling rail R used is one that curves left and right in the horizontal direction, and the three partition panels 1 rotate around the core rod 21 while the joining member 23 and the joined member 24 remain joined.

[0041] 14 is a plan view showing a right-angled arrangement of a partition device equipped with two partition panels 1. The ceiling rail R is a substantially linear one with small-radius corners, and the two partition panels 1 rotate around the core rod 21 while the joining member 23 and the joined member 24 remain joined.

[0042] Figure 15 shows the folded state of a partition device equipped with five partition panels 1. A straight ceiling rail R is used, and the five partition panels 1 are rotated 90 degrees around the core rod 21 while the joining member 23 and the joined member 24 remain joined, and are folded closely together into five layers.

[0043] Figure 16 shows a partition device equipped with five partition panels 1 in a zigzag folded state when unfolded. A straight ceiling rail R is used, and the five partition panels 1 rotate around the core rod 21 while the joining member 23 and the joined member 24 remain joined.

[0044] 19 to 21 show a second embodiment of the lifting runner 9, which has wheels 13 that are rotatably placed on the ceiling rail R, supports 15 that support the wheels 13 via axles 14, a support base 16 that is detachably fixed to the top surface of the upper crosspiece 4, and a connector 17 that penetrates and connects the support base 16 to the support 15 placed thereon. .

[0045] The connector 17 of the second embodiment differs from the connector 17 shown in Figures 5 to 7 in that it has an upper vertical shaft 18U whose upper part is connected to the support body 15 so as to be rotatable relative to the vertical axis, a lower vertical shaft 18D that passes through the support base 16, and an elastic member 19 that resiliently biases the lower vertical shaft 18D downward relative to the support base 16, and the lower part of the upper vertical shaft 18U and the upper part of the lower vertical shaft 18D are connected by a ring 18L.

[0046] In this second embodiment, the lifting runner 9 has a support 15 having wheels 13 and a support base 16 fixed to the upper surface of the upper rail material 4, which can rotate around a connecting device 17, and the upper rail material 4 can be swung up and down (tilted) via an elastic member 19, and the upper rail material 4 can be swung back and forth or moved back and forth via a ring 18L, i.e., lateral shaking (back and forth shaking) of the partition panel 1 is acceptable.

[0047] 17 and 18 show an embodiment in which a partition extension panel 100 is extended below a partition panel 1 having a hanging runner 9. The upper partition panel 1 having the hanging runner 9 has a substantially square panel face 3, while the middle and lower partition extension panels 100, which do not have the hanging runner 9, have substantially the same structure as the rectangular partition panel 1.

[0048] The partition extension panel 100, like the partition panel 1 shown in Figures 1 and 2, has an upper rail 4 and a lower rail 5 formed from grooved material having a longitudinal groove j attached to the upper and lower edges of a rectangular panel face 3, an upper connecting body 6 fixed to both left and right ends of the upper rail 4, and a lower connecting body 7 fixed to both left and right ends of the lower rail 5, with the left and right upper connecting bodies 6 and lower connecting bodies 7 connected by support members 8.

[0049] The left and right upper connecting members 6 and the left and right lower connecting members 7 are the same as those of the partition panel 1, but the left and right upper connecting members 6 do not have a buffer member 20, and instead have a joint device 30 formed by a pin.

[0050] The lower part of the joint device 30 is immersed and fixed in the recess 6b of the upper connecting body 6, and the upper part is immersed and fixed in the recess 7c of the lower connecting body 7 of the partition panel 1, and this joint device 30 connects the upper edge of the partition extension panel 100 to the lower edge of the partition panel 1.

[0051] When another partition extension panel 100 of the same shape is connected below the partition extension panel 100, it is the same as connecting it to the partition panel 1. The partition panel 1 and the partition extension panel 100 may have different heights as long as they have the same width on the left and right.

[0052] The pin joint device 30 linearly extends and connects the partition extension panel 100 below the partition panel 1 having the suspension runner 9, and the partition panel 1 and the partition extension panel 100 hang from the suspension runner 9 as a single panel. However, by replacing the joint device 30 with a bendable one, the upper, middle and lower panels can be bent and sway back and forth relative to one another.

[0053] 22 to 23 and 24 to 25 show first and second modified examples of the joint device 30 used in the partition extension panel 100. In FIG.

[0054] 22-23, instead of a single pin, the joint device 30B is configured as a bendable pin by connecting two short pin materials 40 with a horizontal pin 41, and the two short pin materials 40 can rotate around the horizontal pin 41, thus flexibly connecting the upper end of the partition extension panel 100 to the lower end of the partition panel 1. In other words, the two short pin materials 40 are connected with the horizontal pin 41, and the upper part of the upper short pin material 40 is immersed and fixed in the recess 7c of the lower connecting body 7 of the partition panel 1, and the lower part of the lower short pin material 40 is immersed and fixed in the recess 6b of the upper connecting body 6 of the partition extension panel 100.

[0055] The joint device 30B allows the two short pin members 40 to rotate around the horizontal pin 41, and therefore connects the partition extension panel 100 to the partition panel 1 in a manner that allows the partition panel 100 to bend relatively.

[0056] The second modified joint device 30C shown in Figures 24 and 25 is a joint member made of soft resin having symmetrical arrowhead portions 30a and 30b at the top and bottom, with the upper arrowhead portion 30a fitting into the groove j of the lower crosspiece 5 of the partition panel 1 and abutting against the front flange d and the rear flange e, and the lower upper arrowhead portion 30b fitting into the groove j of the upper crosspiece 4 of the partition extension panel 100 and abutting against the front flange d and the rear flange e, preventing it from slipping out of the groove j.

[0057] This joint tool 30C is also made of soft resin, so the upper and lower arrowheads 30a, 30 b), thereby making the partition extension panel 100 bendable relative to the partition panel 1.

[0058] In the partition panel of the above-mentioned embodiment, an upper crosspiece 4 and a lower crosspiece 5 are attached to the upper and lower edges of a rectangular panel face 3, an upper connector 6 is fixed to both the left and right ends of the upper crosspiece 4, and a lower connector 7 is fixed to both the left and right ends of the lower crosspiece 5, and the left and right upper connectors 6 and lower connectors 7 are connected by support members 8, the upper crosspiece 4 and the lower crosspiece 5 are formed from grooved members having grooves j along the longitudinal direction, the upper connectors 6 and lower connectors 7 have insertion connecting portions 6a that are inserted into and fixed in the grooves j, and a suspension runner 9 is removably attached to the upper crosspiece 4 using the grooves j.

[0059] With this configuration, the upper and lower crosspieces 4 and 5 are formed from grooved members having grooves j along the longitudinal direction, making them lightweight, and the connectors 6, 7 for connecting the support members 8 are provided with insertion connecting portions 6a that are inserted into the grooves j and fixed, allowing for a strong connection.

[0060] In addition, in the partition panel of the above embodiment, the lifting runner 9 has a wheel 13 that is placed so that it can roll on the ceiling rail R, a support 15 that supports the wheel 13 via an axle 14, a support base 16 that is detachably fixed to the upper surface of the upper crosspiece 4, and a connector 17 that penetrates and connects the support base 16 to the support 15 placed above it, and the connector 17 has a vertical shaft 18 whose upper part is connected to the support 15 so that it can rotate relatively around the vertical axis, and the lower part of the vertical shaft 18 penetrates the support base 16 and is provided with an elastic member 19 that elastically urges the support base 16 toward the support 15.

[0061] This configuration not only allows the partition panel 1 to rotate between the support 15 supporting the wheel 13 and the support base 16 fixed to the upper rail material 4, but also allows the partition panel 1 to move and swing in the vertical direction, and can elastically cushion downward loads.

[0062] Furthermore, in the partition panel of the above embodiment, the lifting runner 9 has a wheel 13 that is rotatably placed on the ceiling rail R, a support 15 that supports the wheel 13 via an axle 14, a support base 16 that is detachably fixed to the upper surface of the upper crosspiece 4, and a connector 17 that penetrates and connects the support base 16 to the support 15 placed above it, and the connector 17 has an upper vertical shaft 18U whose upper part is connected to the support 15 so that it can rotate relatively around the vertical axis, a lower vertical shaft 18D that penetrates the support base 16, and an elastic member 19 that resiliently urges the lower vertical shaft 18D downward relative to the support base 16, and the lower part of the upper vertical shaft 18U and the upper part of the lower vertical shaft 18D are connected by a ring 18L.

[0063] This configuration not only allows the partition panel 1 to rotate between the support 15 supporting the wheel 13 and the support base 16 fixed to the upper rail material 4, but also allows the partition panel 1 to move and swing in the vertical direction, elastically cushions downward loads, and can also allow the partition panel 1 to sway sideways.

[0064] Furthermore, in the partition panel of the above embodiment, the left and right upper connecting bodies 6 are provided with buffer members 20 on the upper surface thereof for buffering collision with the ceiling T.

[0065] This configuration makes it possible to prevent the upper connecting body 6 from directly colliding with the ceiling T even when the partition panel 1 swings.

[0066] In addition, in the partition panel of the above embodiment, the left and right support members 8 have a core rod 21 whose upper and lower ends are connected to the upper connecting body 6 and the lower connecting body 7, an outer tube 22 fitted onto this core rod 21 so as to be rotatable around the vertical axis, and a joining member 23 and a joined member 24 arranged above and below this outer tube 22, and the joining member 23 and the joined member 24 can rotate relative to the core rod 21 even when joined.

[0067] With this configuration, the partition panels 1 can be joined side by side using the joining members 23 and the members to be joined 24, and can be easily and smoothly bent or folded in the joined state.

[0068] In the partition panel of the above embodiment, the member to be joined 24 has an arc-shaped outer peripheral surface 24a that is approximately concentric with the core rod 21 and a flat outer surface 24b that protrudes from the side of the connecting body, and an iron plate F is embedded in this flat outer surface 24b, and the joining member 23 has an arc-shaped outer peripheral surface 23a that is approximately concentric with the core rod 21 and a flat outer surface 23b that protrudes from the side of the upper and lower connecting bodies 6, 7, and a magnet M is embedded in the member to be joined 24, and the legs that are magnetically attracted to the iron plate F protrude from the flat outer surface 24b, and the joining member 23 is disposed on the upper side of one of the left and right support members 8 and the lower side of the other. 4 is disposed below one of the left and right support members 8 and above the other.

[0069] This configuration allows the left and right weight balance of one partition panel 1 to be well balanced, the partition panels 1 to be joined side by side, and the joined panels can be easily and smoothly bent or folded.
