Description

[Technical Field]

[0001] The present invention relates to a movable partition panel. [Background technology]

[0002] Conventionally, a partition panel of this type has been known that comprises a panel body having grounding members at both ends of a lower frame and stabilizing legs arranged in a crossed state in the middle of the lower frame (see, for example, Patent Document 1).

[0003] It is also conceivable that this type of partition panel can be configured to be stackable in multiple units. That is, such panels are configured so that a gap is formed between the lower frame of the panel body and the floor surface into which the stabilizing legs of other partition panels of the same structure can be inserted, and multiple panels can be stacked in succession by inserting the stabilizing legs of the front partition panel into the gap formed between the lower frame of the rear partition panel and the floor surface.

[0004] However, conventional stackable partition panels have an opaque panel covering the entire panel body, making it impossible to see from one side to the other. This makes it difficult to smoothly press the front partition panel from one side to move it in the thickness direction and insert the stabilizing legs protruding from the other side of the partition panel under the lower frame of the other partition panel located further back. In other words, because the worker pressing the front partition panel cannot see the other side of the partition panel, the tip of the stabilizing leg is likely to collide with the stabilizing legs of the rear partition panel, making it difficult to insert the tip of the front stabilizing leg into the gap under the lower frame of the rear partition panel as intended (Problem 1).

[0005] Recently, there has been a demand for furniture used in the lobbies of public facilities to be able to adapt its functions and placement to suit the changing circumstances between normal times and disasters. Under this phase-free approach, partition panels and other items are also required to be able to be rearranged quickly and easily, and they need to be reasonably lightweight.

[0006] However, in the above-mentioned system, since the face plate is disposed over the entire area of ​​the panel body, there is a limit to how much weight can be reduced, and some kind of improvement is desired (Problem 2). [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0020] As shown in Figures 1 to 3, 5 to 6, 8 to 10, 12, and 15 to 16, the partition panel P of this embodiment is configured by fastening stabilizing legs 3 to a lower frame 7 of a panel main body 1 via spacers 2 with bolts BB. The stabilizing legs 3 are hollow bodies having cavities 3s on the inner surface of the upper wall 33, and the bolts BB are threaded into nuts (plate nuts 76) provided on the lower frame 7, passing through a backing plate 9 attached to the inner surface of the upper wall 33 of the stabilizing legs 3, the upper wall 33, and the spacers 2. This will be described in detail below.

[0021] As shown mainly in Figures 6 to 8 and 12, the panel main body 1 comprises an outer frame portion 4 having a lower frame 7 with grounding bodies at both ends and left and right side frames 8 standing upright from both the left and right ends of the lower frame 7, and paired front and back face plates 5 and 6 are arranged inside the outer frame portion 4.

[0022] As shown in Figures 8 and 9, the lower frame 7 is a rectangular pipe with a top wall 71, a front wall 72, a back wall 73, and a bottom wall 74. The top wall 71 has three partial cylindrical sections 711 on the inner surface thereof, each with a central female thread 712 and two bilateral female threads 713 on either side of the central female thread 712, and the bottom wall 74 has one partial cylindrical section 741 on the inner surface thereof, with a central female thread 742. The front wall 72 and the back wall 73 have nut-retaining rails 75 formed on their inner surfaces, and plate nuts 76 are slidably fitted onto these rails 75. The plate nuts 76 are used to screw the stabilizing legs 3 to the lower frame 7, and are positioned and locked in the longitudinal center of the lower frame 7 with resin rivets 78. As shown in Figures 10 and 11, the lower frame 7 is made, for example, by cutting an aluminum extrusion to a predetermined length and then performing internal thread forming processing at necessary locations, and both left and right ends are connected to the lower ends of the side frames 8 via brackets B.

[0023] 10-11 and 13-14, the side frame 8 is a hollow column with a flat inner wall 81 and an outer wall 82 that bulges outward, and a cutout 82a that is open downward and outward for inserting a tool is formed in the lower end of the outer wall 82. The bracket B for connecting the side frame 8 and the lower frame 7 is integrally provided with a horizontal part B1 that is screwed to the underside of the bottom wall 74 of the lower frame 7 and a vertical part B2 that extends upward from the outer end of the horizontal part B1, and the inner wall 81 of the side frame 8 is sandwiched between the vertical part B2 and the end face of the lower frame 7. That is, screw insertion holes B2a, 81a corresponding to upper and lower central female screws 712, 742 opening on the end face of the lower frame 7 are formed in the vertical portion B2 of bracket B and the inner wall 81 of side frame 8, respectively, and by threading and tightening set screws SN that pass through the vertical portion B2 of bracket B and the inner wall 81 of side frame 8 into the central female screws 712, 742 of the lower frame 7, the side frame 8 is rigidly connected to the end of the lower frame 7. Note that reinforcing screws HN are threaded into the female screws 713 on both sides of the lower frame 7 in advance, and the heads of these reinforcing screws HN determine the position of the side frame 8 relative to the lower frame 7 and regulate tilting in the front-to-rear direction. Specifically, fitting holes B2b and 81b are formed in the vertical portion B2 of bracket B and the inner wall 81 of side frame 8, into which the heads of the reinforcing screws HN fit. 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 relative to the lower frame 7 is restricted. A first cover 77 is attached to the horizontal portion B1 of bracket B with screws from the underside, and a second cover 83 is fitted to the lower end of the side frame 8 from below. A nut B3 is rigidly connected to the horizontal portion B1 of bracket B, and the threaded portion AJ1 of the adjuster AJ, which serves as a grounding body, is threadedly attached to this nut B3, passing through the first cover 77. Reference numeral 84 denotes an upper end cap made of synthetic resin, fitted to the upper end of the side frame 8.

[0024] As described above, the pair of face plates 5, 6 are arranged inside the outer frame 4, which is equipped with the lower frame 7 and the left and right side frames 8. Horizontal frames 51, 52 are integrally provided on the edge of at least one of the face plates 5, spanning between the left and right side frames 8. The outer surface 5a of one face plate 5 and the outer surfaces 51a, 52a of the horizontal frames 51, 52, which are seamlessly connected to this outer surface 5a, form the writing surface. In other words, this face plate 5 can be used as a whiteboard.

[0025] In this embodiment, one face panel 5 is made of sheet metal and has horizontal frames 51, 52 integrated therein, while the other face panel 6 is made of a lightweight core material 61 with a cloth 62 stretched over it. In other words, the one face panel 5 and the horizontal frames 51, 52 are made integrally from a common sheet metal material. The inner surfaces of the double-sided panels 5, 6 are bonded to each other via a paper core CC.

[0026] More specifically, as shown in Figures 7, 12 and 13, one of the panel boards 5 has a flat panel body 50 that is rectangular when viewed from the front, with upper and lower horizontal frames 51, 52 integrally formed at its upper and lower edges, and mounting plates 53 that are attached to the inside walls of the side frames 8 integrally formed at its left and right edges.

[0027] 7, 12 and 13, the upper horizontal frame 51 comprises a top plate portion 511 extending from the upper edge of the face plate main body 50 toward the back surface, an upper back plate portion 512 hanging downward from the extending end of this top plate portion 511, and an upper folded portion 513 extending forward from the hanging end of this upper back plate portion 512. As shown in FIG. 4, the upper horizontal frame 51 functions as a top board that is integrally formed with the upper edge portion of one of the face plates 5, and both left and right ends of this top board (upper horizontal frame 51) are fitted into upper end caps 84 attached to the upper ends of the left and right side frames 8.

[0028] 13 and 14 , the upper end cap 84 integrally comprises a cap main body 841 having a generally semicircular shape in a plan view and fitted onto the upper end of the side frame 8, a depending tubular portion 842 that protrudes downward from the underside of the cap main body 841 and fits onto the inner periphery of the upper end of the side frame 8, an inward extending portion 843 that extends inward from the inner surface of the cap main body 841, a reinforcing rib 844 that connects the underside of the inward extending portion 843 with the inner surface of the depending tubular portion 842, and a rib connecting wall 845 that connects the tips of these reinforcing ribs 844, and the inward extending portion 843, the reinforcing rib 844, and the rib connecting wall 845 are inserted into the inner periphery of the end of the horizontal frame 51 above the face plate 5. The upper end of the side frame 8 is formed with a notch 8x into which the reinforcing rib 844 fits.

[0029] As shown in Figures 7 and 12, the lower horizontal frame 52 comprises a lower plate portion 521 extending from the lower edge of the panel body 50 toward the back surface, a lower back plate portion 522 standing upward from the extending end of this lower plate portion 521, and a lower fold portion 523 extending forward from the tip of this lower back plate portion 522.

[0030] As shown in FIG. 12, the left and right mounting plates 53 extend rearward from both side edges of the face plate body 50, and are fastened to the inner walls 81 of the side frames 8 with rivets r.

[0031] 7 and 12, the other panel 6 has a cloth 62 stretched over one side of a lightweight core material 61 such as lauan, as described above, and is fitted between the upper folded portion 513 of the upper horizontal frame 51 and the lower folded portion 523 of the lower horizontal frame 52 of one panel 5. A paper core CC is adhesively bonded to the inner surface 6b of the other panel 6, and after attaching one panel 5 to the outer frame 4 with rivets r, the paper core CC is adhesively bonded to the inner surface 5b of one panel 5, thereby bonding the other panel 6 to one panel 5 via the paper core CC.

[0032] 8 to 10 and 15 to 17, the leg body 31 of the stabilizing leg 3 is fastened to the lower frame 7 of the panel main body 1 described above via the spacer 2 using, for example, two bolts BB. The stabilizing leg 3 is hollow, with a cavity 3s on the inner surface of the upper wall 33, and the bolt BB is threaded into a nut (plate nut 76) provided on the lower frame 7, passing through a backing plate 9 attached to the inner surface of the upper wall 33 of the stabilizing leg 3, the upper wall 33, and the spacer 2.

[0033] Specifically, as shown in FIGS. 8 to 10 , the stabilizing leg 3 comprises a leg body 31 made of extruded material and leg end caps 32 attached to both ends of the leg body 31. The leg body 31 is made of extruded material, for example, and is integrally formed with a planar top wall 33, a bottom wall 34, and both side walls 35. As described above, the leg body 31 is hollow, with a cavity 3s on the inner surface of the top wall 33. Both longitudinal ends of the lower surface of the bottom wall 34 are provided with grounding members 36 that can slide on a floor F. Furthermore, rails 37 protrude from the inner surfaces of both side walls 35 to support the backing plate 9 so that it can slide while in contact with the inner surface of the top wall 33. A hole 33a is formed in the longitudinal center of the top wall 33 to allow the lower engaging portion 2B of the spacer 2 to pass through. The lower engaging portion 2B of the spacer 2 that passes through this hole 33a determines the position of the backing plate 9 relative to the stabilizing leg 3. On the other hand, the leg end cap 32 is made of, for example, synthetic resin, and as shown in FIG. 8, has a rounded bottom end 32a.

[0034] The backing plate 9 is held slidably along the inner surface of the upper wall 33 of the stabilizing leg 3 and is made of, for example, a metal plate. The backing plate 9 is generally rectangular in shape when viewed from above, and has a first locking portion 9a at one end in the sliding direction that engages with a first protrusion 23 of a spacer (described later), and a second locking portion 9b at the other end in the sliding direction that engages with a second protrusion 24 of the spacer (described later). Furthermore, the backing plate 9 is provided with a screw insertion hole 9x for inserting a bolt BB therethrough.

[0035] As shown in Figures 8, 9 and 15 to 24, the spacer 2 has upper and lower engagement portions 2A and 2B that engage with the lower frame 7 and the stabilizing leg 3, respectively, to regulate the relative horizontal rotation of the lower frame 7 and the stabilizing leg 3, and as mentioned above, the lower engagement portion 2B that engages with the stabilizing leg 3 also positions the support plate 9 relative to the stabilizing leg 3.

[0036] As shown in Figures 8, 9 and 15 to 17, this spacer 2 comprises a plate-shaped spacer body 21 having a certain thickness, and a cover portion 22 that is fitted onto the outside of this spacer body 21 so as not to rotate relative to it and has upper and lower engagement portions 2A and 2B integrally formed therewith. The spacer body 21 is made of a metal plate, and the cover portion 22 is made of a synthetic resin. The spacer body 21 is provided with screw insertion holes 21x that correspond to the screw insertion holes 9x of the backing plate 9. Reference numerals 21a and 21b are cutouts through which first and second protrusions 23 and 24 of the lower engagement portion 2B pass, respectively.

[0037] As shown in Figures 8 and 16 to 17, the upper engagement portion 2A has a pair of upright walls 25 protruding parallel to one another on the upper surface of the cover portion 22, with the lower portion of the lower frame 7 fitted between these upright walls 25. On the other hand, as shown in Figures 8 and 15 to 24, the lower engagement portion 2B has a first protrusion 23 and a second protrusion 24 hanging down from the lower surface of the cover portion 22, with the lower ends of these first and second protrusions 23, 24 penetrating the upper wall 33 of the stabilizing leg 3 and extending into the stabilizing leg 3.

[0038] 8 and 15 to 24, the lower engagement portion 2B includes a first protrusion 23 that passes through a hole 33a provided in the upper wall 33 of the stabilizing leg 3 and abuts against a first locking portion 9a at one end in the sliding direction of the backing plate 9, and a second protrusion 24 that passes through a hole 33a provided in the upper wall 33 of the stabilizing leg 3 and abuts against a second locking portion 9b at the other end in the sliding direction of the backing plate 9. The first protrusion 23 has a longer protrusion dimension than the second protrusion 24.

[0039] As shown in Figures 19 to 21, this spacer 2 is configured so that it can take an intermediate mounting position (P) relative to the stabilizing leg 3 where only the first protrusion 23 can abut against the backing plate 9, and a final mounting position (Q) where both the first protrusion 23 and the second protrusion 24 can abut against the backing plate 9.

[0040] The assembly method for such a partition panel P comprises the steps of: process I in which the spacer 2 is assembled to the stabilizing leg 3 up to the intermediate mounting position (P); process II in which the backing plate 9 inserted into the stabilizing leg 3 is slid along the upper wall 33 so that the first engaging portion 9a at one end of the backing plate 9 abuts against the first protrusion 23; process III in which, while the backing plate 9 is kept abutting against the first protrusion 23, the spacer 2 is assembled to the final mounting position (Q) so that the second engaging portion 9b at the other end of the backing plate 9 also abuts against the second protrusion 24; and process IV in which a bolt BB is passed through the backing plate 9 and the spacer 2 and screwed into the plate nut 76 of the lower frame 7.

[0041] In step I, 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 drilled in the leg body 31 of the stabilizing leg 3, at least one end of which is open, to assume the intermediate installation position (P) as shown in FIGS. 19 and 22. In step II, with the spacer 2 remaining in the intermediate installation position (P), a backing plate 9 is inserted from one end of the leg body 3. If one end of the leg body 31 is held higher than the other end, the backing plate 9 slides inward of the leg body 31 due to gravity, and the first locking portion 9a at one end (the tip of the sliding movement) abuts and locks against the first protrusion 23 as shown in FIGS. 20 and 23. In step III, after confirming that the backing plate 9 is locked by the first protrusion 23, the spacer 2 is further pressed toward the leg body 31 to move to the final installation position (Q) as shown in FIGS. 21 and 24. At this final installation position (Q), both ends of the first and second protrusions 23 and 24 enter the internal space of the stabilizing leg 3, and the backing plate 9 is positioned there. This positioning is performed with a tolerance for error within a range that does not interfere with the screw installation process. That is, the backing plate 9 is positioned near the longitudinal center of the stabilizing leg 3 with some play allowed. When the spacer 2 is inserted to the final installation position (Q), the elastic claws 23a and 24a on the first and second protrusions 23 and 24 elastically engage with the inner opening ends of the holes 33a drilled in the upper wall 33 of the stabilizing leg 3, as shown in Figures 8 and 24. Therefore, the spacer 2 is stably supported on the upper wall 33 of the stabilizing leg 3. Step IV is a step for screwing the leg body 31 to the lower frame 7 of the panel main body 1 via the spacer 2. First, the screw BB is inserted into the cavity 3s of the leg body 31 through the screw passage hole 34x opened in the bottom wall 34 of the leg body 31. Then, as shown in Figures 15 and 16 , the screw BB is passed through the screw insertion hole 9x of the backing plate 9, the screw insertion hole 33x in the upper wall 33 of the leg body 31, and the screw insertion hole 7x in the lower frame 7, and then threadedly engaged with the plate nut 76 held within the lower frame 7 and tightened, thereby fixing the stabilizing leg 3 to the lower frame 7 of the panel main body 1 via the spacer 2.

[0042] As described above, this partition panel P comprises the panel main body 1 having the adjusters AJ, which serve as grounding members, at both ends of the lower frame 7, and the stabilizing legs 3, which are provided in a crossed state in the middle of the lower frame 7. The upper wall 33 of the stabilizing legs 3 is substantially horizontal, and there is a height difference between the upper wall 33 and the lower frame 7 of the panel main body 1, corresponding to the thickness of the spacer main body 21 of the spacer 2. Therefore, a gap S is formed between the lower frame 7 of the panel main body 1 and the floor F, into which the stabilizing legs 3 of other partition panels P having the same structure can be inserted. That is, with a partition panel P having such a structure, as shown in FIG. 25 , multiple partition panels P can be stacked sequentially by inserting the stabilizing legs 3 of the partition panel P in front into the gap S formed between the lower frame 7 of the partition panel P located at the back and the floor F. The partition panels P are provided with a see-through window W to facilitate stacking. 1, 2, and 25, the partition panel P is provided with a see-through window W in a lower region 1U of the panel main body 1, which allows the floor surface F on the other side to be seen from one side of the panel main body 1. The see-through window W may be any window that is translucent and may be fitted with a glass plate or the like, but in the partition panel P of this embodiment, from the viewpoint of reducing weight, the see-through window W is an opening that does not have any member with a shielding function.

FIG. 25 is a perspective view showing how the partition panels P are stacked.

[0044] With this configuration, the stabilizing leg 3 has a cavity 3s on the inner surface of the upper wall 33, which allows for a significant weight reduction compared to stabilizing leg 3 made from solid die-casting or the like. Moreover, when the upper wall 33 of the stabilizing leg 3 having the cavity 3s is screwed to the lower frame 7 of the panel main 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, so even if the stabilizing leg 3 itself is made thin, deformation of the upper wall 33 can be effectively suppressed. Therefore, even if the weight is reduced by making the constituent materials thinner, it is possible to make the connection between the lower frame 7 of the panel main body 1 and the stabilizing leg 3 a strong structure with high rigidity.

[0045] Furthermore, the spacer 2 is provided with upper and lower engaging portions 2A and 2B, which not only fulfills its primary function of creating space (described later) but also serves to prevent the stabilizing legs 3 from rotating horizontally relative to the panel body 1, thereby reducing the number of parts and promoting weight reduction. Furthermore, the lower engaging portion 2B of the spacer 2 also determines the position of the backing plate 9 relative to the stabilizing legs 3, thereby particularly reducing the number of parts. Incidentally, by interposing the spacer 2 between the lower frame 7 of the panel body 1 and the upper surface of the stabilizing legs 3, as in this partition panel P, a height difference between the lower frame 7 and the upper surface of the stabilizing legs 3 can be naturally formed. This makes it easy to secure a relatively large gap S between the lower surface of the lower frame 7 and the floor F. Therefore, even if the leg body 31 of the stabilizing legs 3 is made of a simple-shaped member such as an extrusion-molded product, it is possible to realize a stackable partition panel as shown in FIG. 25.

[0046] Furthermore, the engagement portion 2B below the spacer 2 is composed of first and second protrusions 23, 24 of different lengths, and these protrusions 23, 24 are inserted sequentially into the stabilizing leg 3 to engage the backing plate 9. This means that the backing plate 9 can be easily and reliably positioned in the specified position without using any special engaging parts, which also helps to reduce the number of parts and the assembly structure.

[0047] Furthermore, the spacer 2 comprises a plate-shaped spacer body 21 having a certain thickness, and a cover part 22 which is fitted onto the outside of the spacer body 21 so as not to be able to rotate relative to it and which is integrally provided with the engaging parts 2A and 2B. Therefore, each part can be made from the most suitable material, and it is easier to select the material and the processing method than when they are made integrally.

[0048] Moreover, this partition panel P is provided with a see-through window W in the lower region of the panel body 1, which allows the floor surface F on the other side (outer surface 6a of the other panel 6) of the panel body 1 to be viewed from one side (outer surface 5a of one panel 5) of the panel body 1, thereby enabling smooth and quick stacking of multiple partition panels P. That is, this partition panel P is provided with adjusters AJ, which are ground contact bodies that can slide freely in any direction on the floor surface F, at both ends of the lower frame 7, and with ground contact bodies 36, which can also slide freely in any direction on the floor surface F, at both ends of the stabilizing legs 3 fixed to the lower frame 7. Therefore, when the front partition panel P, which is arranged parallel to the front of the rear partition panel P, is pressed in the thickness direction, the front partition panel P approaches the rear partition panel P while maintaining an approximately parallel posture, and the tip of the stabilizing leg 3 of the front partition panel P is inserted into the gap S between the lower frame 7 of the rear partition panel P and the floor surface F, causing the two partition panels P to overlap in the thickness direction and become stacked.

[0049] By repeating the above operations, it is possible to stack multiple partition panels P compactly, and the partition panel P of the present invention has a see-through window W in the lower region of the panel body 1, which allows the floor surface F on the other side of the panel body 1 to be seen from one side of the panel body 1. Therefore, when stacking, the stabilizing legs 3 of the moving partition panel P can be stacked smoothly without colliding with the stabilizing legs 3 or adjusters AJ of the stationary partition panel P at the back.

[0050] Furthermore, as mentioned above, the viewing window W is an opening that does not contain any components with a shielding function, so it can be made lighter than if a shielding member such as a glass plate were provided in the window.

[0051] Furthermore, as mentioned above, the stabilizing leg 3 is provided with a leg body 31 having a flat upper wall 33, and this leg body 31 is attached to the lower frame 7 of the panel main body 1 via the spacer 2, so that a height difference can be naturally formed between the lower frame 7 and the upper surface of the stabilizing leg 3. This makes it easy to ensure a relatively large gap S between the underside of the lower frame 7 and the floor surface F, and even if the leg body 31 of the stabilizing leg 3 is made of a member with a simple shape such as an extrusion molded product, it is possible to realize a stackable partition panel as shown in Figure 25.

[0052] Furthermore, the stabilizing legs 3 are each equipped with a leg body 31 made of extruded material and leg tip caps 32 attached to both ends of the leg body 31, thereby simplifying the structure of the stabilizing legs 3. Furthermore, because the lower tips 32a of the leg tip caps 32 are rounded, when inserting the stabilizing legs 3 into the gap S between the underside of the lower frame 7 and the floor F for stacking, the stacking operation can be carried out smoothly by, for example, first inserting the lower tips 32a of the leg tip caps 32 into the gap S with the lower tips 32a in contact with the floor F, and then standing up the partition panel P.

[0053] In addition, since the cover portion 22 of the spacer 2 is made of synthetic resin, even if the cover portion 22 comes into contact with the lower frame 7 of another partition panel P during stacking, the lower frame will not be damaged.

[0054] The present invention is not limited to the above-described embodiment.

[0055] As in the above-described embodiment, if the panel body comprises an outer frame including a lower frame, and paired front and back panel panels arranged inside this outer frame, and a see-through window is formed between the lower edge of the panel panel and the lower frame, it is possible to reduce the weight by devising the material and shape of the paired panel panels and the method of joining them, compared to a configuration in which a panel that is an integral whole is fitted into the outer frame.

[0056] As in the above-described embodiment, if one panel is made of a rigid panel material made of sheet metal and the other panel is made of a lightweight core material with cloth stretched on one side thereof, a paper core can be placed between the panels and glued to the inner surface of the double-sided panel, thereby effectively reducing the overall weight with a simple configuration.

[0057] In the above-described embodiment, in order to reduce weight, the viewing window is an opening without any member having a shielding function.

[0058] In addition, the shape and configuration of the stabilizing legs are not limited to those described in the above-described embodiments, and any other shape and configuration may be adopted, such as one in which the entire legs are integrally molded by die-cast molding or the like.

[0059] In addition, various modifications may be made within the scope of the present invention without departing from the spirit of the present invention. [Explanation of symbols]
