Mode for Carrying Out the Invention

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0017] As shown in FIGS. 1 to 3, FIGS. 5 to 6, FIGS. 8 to 10, FIG. 12, and FIGS. 15 to 16, the partition panel P of this embodiment is formed by fixing the stabilizing legs 3 to the lower frame 7 of the panel body 1 via spacers 2 with bolts BB. The stabilizing legs 3 are hollow bodies having cavities 3s on the inner surface side of the upper wall 33. The bolts BB penetrate the backing plate 9 attached to the inner surface of the upper wall 33 of the stabilizing legs 3, the upper wall 33 thereof, and the spacers 2 and are screwed to nuts (plate nuts 76) provided on the lower frame 7. This will be described in detail below.

[0018] As mainly shown in FIGS. 6 to 8 and FIG. 12, the panel body 1 includes an outer frame portion 4 having a lower frame 7 with grounding bodies at both ends and left and right side frames 8 erected from both left and right ends of the lower frame 7. Inside the outer frame portion 4, front and back facing front and back plates 5 and 6 are arranged.

[0019] As shown in FIGS. 8 and 9, the lower frame 7 is in the shape of a square prism pipe having a top wall 71, a front wall 72, a back wall 73, and a bottom wall 74. On the inner surface side of the top wall 71, it has three partial cylindrical portions 711 each formed with a central female thread 712 and both side female threads 713 located on both sides of the central female thread 712, and on the inner surface side of the bottom wall 74, it has one partial cylindrical portion 741 formed with a central female thread 742. Further, on the inner surfaces of the front wall 72 and the back wall 73, rail portions 75 for holding nuts are formed, and plate nuts 76 are slidably fitted to these rail portions 75. This plate nut 76 is for screwing the stabilizing legs 3 to the lower frame 7 and is locked in a positioned state by resin rivets 78 at the central position in the longitudinal direction of the lower frame 7. The lower frame 7 is made, for example, by cutting an extruded product made of aluminum to a predetermined length and then performing female thread forming processing and the like at necessary locations, and both left and right ends are connected to the lower ends of the side frames 8 via brackets B.

[0020] As shown in FIGS. 10 to 11 and FIGS. 13 to 14, the side frame 8 is a hollow columnar member having a flat inner wall 81 and an outer wall 82 that bulges outward. A notch 82a for inserting a tool, which is open downward and outward, is formed at the lower end of the outer wall 82. The bracket B for connecting the side frame 8 and the lower frame 7 integrally includes a horizontal portion B1 that is screwed to the lower surface of the bottom wall 74 of the lower frame 7, and a vertical portion B2 that extends upward from the outer end of the horizontal portion B1. The inner wall 81 of the side frame 8 is clamped by the vertical portion B2 of the bracket B and the end face of the lower frame 7. That is, screw insertion holes B2a and 81a corresponding to the upper and lower central female screws 712 and 742 opened in the end face of the lower frame 7 are respectively formed in the vertical portion B2 of the bracket B and the inner wall 81 of the side frame 8. By screwing and tightening a fastening screw SN that penetrates the vertical portion B2 of the bracket B and the inner wall 81 of the side frame 8 into the central female screws 712 and 742 of the lower frame 7, the side frame 8 is rigidly connected to the end of the lower frame 7. Reinforcing screws HN are pre-screwed into the both-side female screws 713 of the lower frame 7, and the heads of these reinforcing screws HN position the side frame 8 with respect to the lower frame 7 and regulate tilting in the front-rear direction. That is, fitting holes B2b and 81b into which the heads of the reinforcing screws HN are fitted are formed in the vertical portion B2 of the bracket B and the inner wall 81 of the side frame 8. By fitting the heads of the reinforcing screws HN into these fitting holes B2b and 81b, tilting of the side frame 8 in the panel thickness direction with respect to the lower frame 7 is regulated. A first cover 77 screwed from the lower surface side is attached to the horizontal portion B1 of the bracket B, and a second cover 83 is fitted to the lower end portion of the side frame 8 from the lower side. A nut B3 is rigidly connected to the horizontal portion B1 of the bracket B, and a screw portion AJ1 of an adjuster AJ, which is a grounding body, is screwed through the first cover 77 into the nut B3. Reference numeral 84 denotes an upper end cap made of synthetic resin fitted to the upper end portion of the side frame 8.

[0021] Inside the outer frame portion 4 including the lower frame 7 and the left and right side frames 8 as described above, as described above, the front and back facing front and back plates 5 and 6 are arranged, and horizontal frames 51 and 52 spanning between the left and right side frames 8 are integrally provided at the edge of at least one of the front plates 5. Here, the outer surface 5a of one of the front plates 5 and the outer surfaces 51a and 52a of the horizontal frames 51 and 52 that are continuously connected to the outer surface 5a without interruption form a writing surface. That is, this front plate 5 can be used as a whiteboard.

[0022] In this embodiment, one of the front plates 5 is made of sheet metal integrally provided with the horizontal frames 51 and 52, and the other front plate 6 is formed by stretching a cloth 62 over a lightweight core material 61. That is, one of the front plates 5 and the horizontal frames 51 and 52 are integrally made of a common sheet metal material. And the inner surfaces of both front plates 5 and 6 are adhered to each other via a paper core CC.

[0023] Specifically, as shown in FIGS. 7, 12, and 13, one of the front plates 5 includes a flat plate-shaped front plate body 50 having a rectangular shape when viewed from the front, and upper and lower horizontal frames 51 and 52 are integrally formed at the upper and lower edge portions thereof, and mounting plates 53 that abut against the inner side walls of the side frames 8 are integrally formed at the left and right edge portions.

[0024] As shown in FIGS. 7, 12, and 13, the upper horizontal frame 51 includes a top plate portion 511 that extends from the upper edge of the front plate body 50 in the back surface direction, an upper back plate portion 512 that hangs downward from the extending end of the top plate portion 511, and an upper return portion 513 that extends forward from the hanging lower end of the upper back plate portion 512. The upper horizontal frame 51 functions as a drip edge integrally provided at the upper edge portion of one of the front plates 5 as shown in FIG. 4, and both left and right ends of this drip edge (upper horizontal frame 51) are fitted into upper end caps 84 mounted on the upper ends of the left and right side frames 8.

[0025] As shown in FIGS. 13 and 14, the upper cap 84 includes a cap body 841 having a substantially semi-circular shape in plan view that covers the upper end of the side frame 8, a hanging cylinder portion 842 that protrudes downward from the lower surface of the cap body 841 and fits into the inner periphery of the upper end portion of the side frame 8, an inward extension portion 843 that extends inward from the inner surface of the cap body 841, a reinforcing rib 844 that integrally connects the lower surface of the inward extension portion 843 and the inward surface of the hanging cylinder portion 842, and a rib connecting wall 845 that connects between the tips of these reinforcing ribs 844. The inward extension portion 843, the reinforcing rib 844, and the rib connecting wall 845 are inserted into the inner periphery of the end portion of the horizontal frame 51 on the panel 5. A notch portion 8x into which the reinforcing rib 844 is fitted is formed at the upper end portion of the side frame 8.

[0026] As shown in FIGS. 7 and 12, the lower horizontal frame 52 includes a lower plate portion 521 that extends from the lower edge of the panel body 50 in the back surface direction, a lower back plate portion 522 that stands up upward from the extending end of the lower plate portion 521, and a lower folding-back portion 523 that extends forward from the tip of the lower back plate portion 522.

[0027] As shown in FIG. 12, the left and right mounting plates 53 extend from both side edges of the panel body 50 in the back surface direction respectively and are fixed to the inner wall 81 of the side frame 8 using rivets r.

[0028] As shown in FIGS. 7 and 12, the other panel 6 has a cloth 62 stretched on one side of a lightweight core material 61 such as a lauan material as described above, and is fitted between the upper folding-back portion 513 of the upper horizontal frame 51 and the lower folding-back portion 523 of the lower horizontal frame 52 in the one panel 5. A paper core CC is adhered to the inner surface 6b of the other panel 6 using an adhesive. After attaching the one panel 5 to the outer frame portion 4 with rivets r, the other panel 6 is adhered to the one panel 5 via the paper core CC by adhering the paper core CC to the inner surface 5b of the one panel 5 using an adhesive.

[0029] As shown in FIGS. 8 to 10 and FIGS. 15 to 17, the leg body 31 of the stabilizer leg 3 is fixed to the lower frame 7 of the panel body 1 described above via a spacer 2, for example, using two bolts BB. The stabilizer leg 3 is a hollow body having a cavity 3s on the inner surface side of the upper wall 33. The bolt BB is screwed into a nut (plate nut 76) provided on the lower frame 7 through a backing plate 9 attached to the inner surface of the upper wall 33 of the stabilizer leg 3, the upper wall 33 thereof, and the spacer 2.

[0030] Specifically described, as shown in FIGS. 8 to 10, the stabilizer leg 3 includes an extruded leg body 31 and leg tips 32 attached to both ends of the leg body 31. The leg body 31 is made of an extruded molding material integrally provided with, for example, a flat upper wall 33, a bottom wall 34, and both side walls 35. As described above, the leg body 31 has a hollow shape with a cavity 3s on the inner surface side of the upper wall 33, and grounding members 36 that can slide on the floor surface F are provided at both longitudinal ends of the lower surface of the bottom wall 34. Further, on the inner surface side of both side walls 35, rails 37 are protruding for supporting the backing plate 9 so as to be slidable in a state of being in contact with the inner surface of the upper wall 33. A hole 33a for passing a lower engaging portion 2B of the spacer 2 described later is provided at the longitudinal center of the upper wall 33, and the lower engaging portion 2B of the spacer 2 passing through the hole 33a positions the backing plate 9 with respect to the stabilizer leg 3. On the other hand, the leg tip 32 is made of, for example, synthetic resin, and as shown in FIG. 8, an R is provided at the tip end portion 32a of the lower surface.

[0031] The backing plate 9 is slidably held along the inner surface of the upper wall 33 of the stabilizer leg 3 and is made of, for example, a metal plate. The backing plate 9 is substantially rectangular in plan view, and a first locking portion 9a that engages with a first protrusion 23 of a spacer described later is formed at one end in the sliding direction, and a second locking portion 9b that engages with a second protrusion 24 of the spacer described later is formed at the other end in the sliding direction. Further, a screw insertion hole 9x for inserting the bolt BB is formed in the backing plate 9.

[0032] As shown in FIGS. 8, 9, and 15 to 24, the spacer 2 is provided with upper and lower engaging portions 2A and 2B that engage with the lower frame 7 and the stabilizing leg 3, respectively, to restrict the relative horizontal rotation of the lower frame 7 and the stabilizing leg 3. As described above, the lower engaging portion 2B that engages with the stabilizing leg 3 also positions the contact plate 9 with respect to the stabilizing leg 3.

[0033] As shown in FIGS. 8, 9, and 15 to 17, this spacer 2 includes a plate-shaped spacer body 21 having a constant thickness, and a cover portion 22 that is non-rotatably externally fitted to the outside of the spacer body 21 and integrally has the upper and lower engaging portions 2A and 2B. The spacer body 21 is made of a metal plate, and the cover portion 22 is made of a synthetic resin. A screw insertion hole 21x corresponding to the screw insertion hole 9x of the contact plate 9 is formed in the spacer body 21. 21a and 21b are notches for passing through the first and second protrusions 23 and 24 of the lower engaging portion 2B, respectively.

[0034] As shown in FIGS. 8 and 16 to 17, the upper engaging portion 2A is formed by projecting a pair of upright walls 25 in parallel on the upper surface of the cover portion 22, and the lower part of the lower frame 7 is fitted between these upright walls 25. On the other hand, as shown in FIGS. 8 and 15 to 24, the lower engaging portion 2B has a first protrusion 23 and a second protrusion 24 hanging down from the lower surface of the cover portion 22. The lower ends of these first and second protrusions 23 and 24 penetrate the upper wall 33 of the stabilizing leg 3 and enter the stabilizing leg 3.

[0035] More specifically, as shown in FIGS. 8 and 15 to 24, the lower engaging portion 2B includes a first protrusion 23 that penetrates a hole 33a provided in the upper wall 33 of the stabilizing leg 3 and abuts against a first locking portion 9a on one end side in the sliding direction of the contact plate 9, and a second protrusion 24 that penetrates the hole 33a provided in the upper wall 33 of the stabilizing leg 3 and abuts against a second locking portion 9b on the other end side in the sliding direction of the contact plate 9. The first protrusion 23 has a protruding dimension longer than that of the second protrusion 24.

[0036] As shown in FIGS. 19 to 21, this spacer 2 is configured to be able to take an intermediate mounting position (P) where only the first protrusion 23 can contact the contact plate 9 and a final mounting position (Q) where both the first protrusion 23 and the second protrusion 24 can contact the contact plate 9 with respect to the stabilizing leg 3.

[0037] The method for assembling such a partition panel P includes a step I of assembling the spacer 2 to the stabilizing leg 3 up to the intermediate mounting position (P), a step II of sliding the contact plate 9 inserted into the stabilizing leg 3 along the upper wall 33 and bringing the first locking portion 9a on one end side thereof into contact with the first protrusion 23, a step III of assembling the spacer 2 up to the final mounting position (Q) while keeping the contact plate 9 in contact with the first protrusion 23 and bringing the second locking portion 9b on the other end side of the contact plate 9 into contact with the second protrusion 24, and a step IV of passing a bolt BB through the contact plate 9 and the spacer 2 and screwing it into the plate nut 76 of the lower frame 7.

[0038] In Step I, starting from the initial state shown in Fig. 18, the tip of the first protrusion 23 of the spacer 2 is inserted into the hole 33a formed in the leg body 31 of the stable leg 3 with at least one end open, and the intermediate mounting position (P) is adopted as shown in Figs. 19 and 22. In Step II, while keeping the spacer 2 stopped at the intermediate mounting position (P), the contact plate 9 is inserted from one end of the leg body 3. At this time, if one end side of the leg body 31 is held higher than the other end side, the contact plate 9 will slide inward of the leg body 31 due to gravity, and the first locking portion 9a on its one end side (the sliding movement tip side) will abut against and be locked to the first protrusion 23 as shown in Figs. 20 and 23. In Step III, after confirming that the contact plate 9 is locked to the first protrusion 23, the spacer 2 is further pressed in the direction of the leg body 31 to shift to the final mounting position (Q) as shown in Figs. 21 and 24. At this final mounting position (Q), both tips of the first and second protrusions 23 and 24 will penetrate into the internal space of the stable leg 3, and the contact plate 9 will be positioned at that position. Note that this positioning is performed in a state that allows an error within a range that does not interfere with the screw mounting operation. That is, the contact plate 9 is positioned in a state allowing some play near the center in the longitudinal direction of the stable leg 3. In the state where the spacer 2 is inserted to the final mounting position (Q), the elastic claws 23a and 24a provided on the first and second protrusions 23 and 24 will elastically engage with the inner surface side opening end of the hole 33a formed in the upper wall 33 of the stable leg 3 as shown in Figs. 8 and 24. Therefore, the spacer 2 will be stably supported by the upper wall 33 of the stable leg 3. Step IV is a step for screwing the leg body 31 to the lower frame 7 of the panel body 1 via such a spacer 2. First, the screw BB is inserted into the cavity 3s of the leg body 31 through the screw passage hole 34x formed in the bottom wall 34 of the leg body 31. Then, as shown in Figs. 15 and 16, the screw BB is screwed and tightened with the screw insertion hole 9x of the contact plate 9, the screw insertion hole 33x of the upper wall 33 of the leg body 31, and the screw insertion hole 7x of the lower frame 7 into the plate nut 76 held in the lower frame 7, so that the stable leg 3 is fixed to the lower frame 7 of the panel body 1 via the spacer 2.

[0039] As described above, this partition panel P includes a panel body 1 having adjusters AJ, which are grounding bodies, at both ends of the lower frame 7, and stabilizing legs 3 provided in a crossed state in the middle of the lower frame 7. The upper wall 33 of the stabilizing leg 3 is substantially horizontal, and there is a height difference corresponding to the thickness of the spacer body 21 of the spacer 2 between the upper wall 33 and the lower frame 7 of the panel body 1. Therefore, a gap S into which the stabilizing legs 3 of other partition panels P having the same structure can be inserted is formed between the lower frame 7 of the panel body 1 and the floor surface F. That is, according to the partition panel P having such a structure, as shown in FIG. 25, the stabilizing legs 3 of the front partition panel P can be inserted into the gap S formed between the lower frame 7 of the partition panel P arranged in the back and the floor surface F, and a plurality of panels can be sequentially stacked. The partition panel P is provided with a perspective window W for facilitating the stacking operation. That is, as shown in FIGS. 1, 2, and 25, the partition panel P is provided with a perspective window W in the lower region of the panel body 1 for visually recognizing the floor surface F on the other side from one side of the panel body 1. The perspective window W only needs to have translucency and may be equipped with a glass plate or the like. In the partition panel P of the present embodiment, from the viewpoint of weight reduction, the perspective window W is an opening without a member having a shielding function.

In FIGS. 18 to 21, the spacer 2 shows a cross-section along line F-F in FIG. 17, and the contact plate 9 shows a cross-section along line G-G in FIG. 17. FIG. 22 is a cross-sectional view taken along line X-X in FIG. 19. FIG. 23 is a cross-sectional view taken along line Y-Y in FIG. 20. FIG. 24 is a cross-sectional view taken along line Z-Z in FIG. 21. FIG. 25 is a perspective view showing the stacking mode of the partition panel P.

[0041] With such a configuration, since the stabilizing leg 3 has a cavity 3s on the inner surface side of the upper wall 33, a significant weight reduction can be achieved compared to the case where the stabilizing leg 3 is made of solid die-casting or the like. Moreover, when screwing the upper wall 33 of the stabilizing leg 3 having the cavity 3s to the lower frame 7 of the panel body 1, a backing plate 9 is interposed between the head of the screw BB and the upper wall 33 of the stabilizing leg 3. Therefore, even if the stabilizing leg 3 itself is made thinner, deformation of its upper wall 33 can be effectively suppressed. As a result, even if the constituent material is made thinner to reduce the weight, it is possible to create a strong structure with high rigidity at the connection portion between the lower frame 7 of the panel body 1 and the stabilizing leg 3.

[0042] Also, since the spacer 2 is provided with upper and lower engaging portions 2A and 2B, it can not only perform the original space forming function described later, but also bear the function of preventing the stabilizing leg 3 from horizontally rotating with respect to the panel body 1. It is possible to suppress an increase in the number of parts and promote weight reduction. Moreover, by devising the lower engaging portion 2B of the spacer 2, positioning of the backing plate 9 with respect to the stabilizing leg 3 is also performed, so that in particular, the number of parts can be reduced. In addition, if a spacer 2 is interposed between the lower frame 7 of the panel body 1 and the upper surface of the stabilizing leg 3 like this partition panel P, a height difference can be easily formed between the lower frame 7 and the upper surface of the stabilizing leg 3. Therefore, it becomes easy to secure a relatively large gap S between the lower surface of the lower frame 7 and the floor surface F, and even if the leg body 31 of the stabilizing leg 3 is composed of a member having a simple shape such as an extruded product, it is possible to realize a stackable partition panel as shown in Fig. 25.

[0043] Furthermore, the lower engaging portion 2B of the spacer 2 is constituted by first and second protrusions 23 and 24 having different lengths, and these protrusions 23 and 24 are sequentially inserted into the stabilizing leg 3 to lock the backing plate 9. Therefore, the backing plate 9 can be simply and surely positioned at a predetermined position without using special locking parts. Also from this point, the number of parts and the assembly structure can be reduced.

[0044] The spacer 2 is composed of a plate-shaped spacer body 21 having a constant thickness and a cover portion 22 that is non-rotatably fitted on the outside of the spacer body 21 and integrally includes the engaging portions 2A and 2B. Therefore, each part can be made of an optimal material, and the selection of materials and processing methods can be easily performed compared to the case of making them integrally.

[0045] Note that the present invention is not limited to the embodiments described above.

[0046] For example, the present invention can of course be applied to partition panels that cannot be stacked or partition panels without a perspective window for facilitating the stacking operation. It can also of course be applied to partition panels in a mode where stabilizing legs are attached to the lower frame of a panel body having an outer frame portion with an upper frame and a lower frame.

[0047] Also, in the above-described embodiment, the spacer includes upper and lower engaging portions that respectively engage with the lower frame and the stabilizing legs to restrict the relative horizontal rotation of the lower frame and the stabilizing legs. The lower engaging portion that engages with the stabilizing legs also positions the backing plate with respect to the stabilizing legs. In the case of the above-described embodiment, as described above, the spacer can also bear the function of preventing the horizontal rotation of the stabilizing legs, and the number of parts can be reduced.

[0048] Furthermore, in the above-described embodiment, the backing plate is slidably held along the inner surface of the upper wall of the stabilizing leg, and the lower engaging portion of the spacer includes a first protrusion that penetrates the upper wall of the stabilizing leg and abuts against one end side in the sliding direction of the backing plate, and a second protrusion that penetrates the upper wall of the stabilizing leg and abuts against the other end side in the sliding direction of the backing plate. However, any mode of positioning the backing plate with respect to the stabilizing leg may be adopted. However, in the case of the above-described embodiment, the reduction of the number of parts can be effectively achieved.

[0049] In addition, in the above-described embodiment, the first protrusion has a protruding dimension longer than that of the second protrusion, and the spacer is configured to be able to take an intermediate mounting position where only the first protrusion can contact the contact plate with respect to the stabilizing leg, and a final mounting position where both the first protrusion and the second protrusion can contact the contact plate. However, any mode of attaching the spacer to the stabilizing leg may be adopted. However, if it is like the above-described embodiment, as described above, the contact plate can be easily and surely positioned at a predetermined position without using a special locking part, and from this point, the number of parts and the assembly structure can be reduced.

[0050] Furthermore, in the above-described embodiment, the spacer includes a plate-like spacer body having a constant thickness, and a cover portion that is non-rotatably externally fitted to the outside of the spacer body and integrally includes the engaging portion. However, it is of course possible to integrally form the whole. However, if it is like the above-described embodiment, as described above, each part can be made of an optimal material, and the selection of materials and the selection of processing methods can be easily performed compared to the case of integrally forming.

[0051] And, any procedure for assembling the partition panel of the present invention may be adopted.

[0052] In addition, various modifications may be made without departing from the gist of the present invention.
