Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, as described above, since the display stand of Patent Document 1 is made of paper such as cardboard, it may be affected by the weather and humidity, and the canopy body may be deformed such as warping. When the canopy body warps, a large gap is formed at the joint between the canopy body and the side wall body, and there is a problem that the design of the display stand is impaired (the appearance is poor).

Means for Solving the Problems

[0005] An object of the present invention is to provide furniture that has been studied and improved in view of the above-described situation.

[0006] The present invention relates to a furniture item comprising a polygonal cylindrical side wall body, a polygonal lid-shaped top cover body that covers the upper surface of the side wall body, and a core body that supports the side wall body and the top cover body from the inside. At the upper end portions of each side plate in the side wall body, inward side horizontal flaps are continuously provided. At the lower end portions of each top side plate in the top cover body, inward top horizontal flaps are continuously provided. Horizontal engaging means that fit into each other in the inner and outer directions are formed between each side horizontal flap, the corresponding top horizontal flap, and the core body. Each side horizontal flap and the corresponding top horizontal flap overlap vertically in a state where the horizontal engaging means are fitted together.

[0007] In the furniture item of the present invention, inward side vertical flaps are continuously provided at both side end portions of the side wall body. The core body has a plurality of polygonal plate-shaped partition plates arranged at appropriate intervals in the vertical direction, and a plurality of vertically long leg plates attached around the partition plate group. Vertical engaging means that fit into each other in the inner and outer directions are formed between each side vertical flap and the core body. The vertical engaging means has an outwardly opening outer vertical cut groove formed in each partition plate, and an inner vertical engaging portion corresponding to the outer vertical cut groove of each partition plate in the side vertical flap. The uppermost inner vertical engaging portion in each side vertical flap may be in the shape of a vertical plate and inserted into the uppermost outer vertical cut groove.

Effects of the Invention

[0008] According to the furniture item of the present invention, since each side horizontal flap and the corresponding top horizontal flap overlap vertically in a state where the horizontal engaging means are fitted together, even if the top cover body is about to warp (deform) under the influence of weather or humidity, each top horizontal flap of the top cover body will be caught by the core body via the horizontal engaging means, and the deformation of the top cover body is suppressed. For this reason, it becomes difficult for a large gap to form at the joint portion between the top cover body and the side wall body, making the joint portion inconspicuous and creating a sense of unity between the top cover body and the side wall body. As a result, the appearance (design quality) of the entire furniture item is improved.

[0009] ​ In the furniture according to the present invention, as described above, each side horizontal flap and the corresponding top horizontal flap are vertically overlapped with the horizontal engaging means fitted together. Therefore, when disassembling the furniture, it is removed from the side wall body instead of the lid body. In this case, if the uppermost inner vertical engaging portion of each side vertical flap is formed in a vertical plate shape and inserted into the uppermost outer vertical cutting groove, the engagement of the vertical engaging means in the side wall body can be smoothly released.

Embodiments for Carrying Out the Invention

[0011] Next, embodiments embodying the present invention will be described with reference to the drawings.

[0012] As shown in FIGS. 1 and 2, the furniture 1 of the embodiment includes a polygonal cylindrical side wall body 2, a polygonal lid-shaped (downward-opening box-shaped) top cover body 3 that covers the upper surface of the side wall body 2, and an assembled core body 4 that supports the side wall body 2 and the top cover body 3 from the inside. The side wall body 2 and the top cover body 3 are each obtained by cutting out necessary portions from a single sheet in the unfolded state shown in FIG. 3 or FIG. 4. By performing a bending operation from the unfolded state, the furniture 1 having a polygonal columnar outer shape is formed. That is, after attaching the top cover body 3 to the upper end side of the assembled core body 4, the furniture 1 is formed by wrapping the outer peripheral side of the core body 4 with the side wall body 2 unfolded in a planar shape into a polygonal cylinder. In the embodiment, the outer shape of the furniture 1 is in the shape of a quadrangular prism.

[0013] The side wall body 2, the top cover body 3, and the core body 4 are made of, for example, thin cardboard or thick paper. The materials of the side wall body 2, the top cover body 3, or the core body 4 may be veneer boards, plastic boards, or the like. Note that the side wall body 2 and the top cover body 3 may be configured by a plurality of sheets.

[0014] As shown in FIG. 3, the side wall body 2 surrounds the outer periphery of the furniture 1 (constitutes the outer peripheral wall). Since the outer shape of the furniture 1 is a quadrangular prism, it has three vertically long rectangular side plates 5 and two vertically long rectangular half side plates 6. The half side plates 6 have the same vertical length as each side plate 5, but the horizontal length is set to half of that of each side plate 5. The three side plates 5 are connected in the horizontal direction via vertical fold lines 7a. On both side plates 5 on the outer side in the horizontal direction, half side plates 6 are connected via vertical fold lines 7b are connected.

[0015] On the upper end portions of the respective side plates 5, 6 (including the half side plates 6) of the side wall body 2, side horizontal flaps 8, 9 that are bent inward are connected via horizontal fold lines 10. Inward-opening inner horizontal cut grooves 11 that fit into the outer horizontal cut grooves 25 of the respective leg plates 21 described later are formed in the respective side horizontal flaps 8, 9. In the embodiment, two inner horizontal cut grooves 11 are formed in each side horizontal flap 8 of each side plate 5, and one inner horizontal cut groove 11 is formed in each side horizontal flap 9 of each half side plate 6.

[0016] At both side end portions of the side wall body 2, that is, on both half side plates 6 on the outer side in the lateral direction, side vertical flaps 12 that are bent inward are continuously provided via vertical folding lines 7c. Therefore, on each half side plate 6, a side horizontal flap 9 and a side vertical flap 12 are continuously provided. On each side vertical flap 12, an inclined side portion 13 as an inner vertical engaging portion that fits into an outer vertical cut groove 24 of each partition plate 20 described later and an inner vertical cut groove 14 are formed. In the embodiment, an inclined side portion 13 that is cut out with a gentle gradient with respect to the vertical is formed at the upper portion of each side vertical flap 12. Inner vertical cut grooves 14 that are open inward are formed at appropriate intervals in the vertical direction at the upper and lower middle portions and the lower portion of each side vertical flap 12.

[0017] As shown in FIG. 4, the top cover body 3 covers the upper surface of the side wall body 2 and has a top plate 15 that is rectangular in plan view and four top side plates 16 continuously provided around the periphery of the top plate 15. The top side plates 16 are continuously provided at each peripheral edge of the top plate 15 via horizontal folding lines 18a. On each top side plate 16, a top horizontal flap 17 is continuously provided via a horizontal folding line 18b. On each top horizontal flap 17, an inner horizontal cut groove 19 that is open inward and fits into an outer horizontal cut groove 25 of each foot plate 21 described later is formed in the same manner as each of the side horizontal flaps 8 and 9 described above. In the embodiment, two inner horizontal cut grooves 19 are formed in each top horizontal flap 17. As can be seen from FIGS. 8(b) and 9(b), the width Wa in the short side direction of the side horizontal flaps 8 and 9 is longer than the width Wb in the short side direction of the top horizontal flap 17.

[0018] As shown in FIGS. 5 and 6, the core body 4 is an assembled type that supports the side wall body 2 and the ceiling body 3 from the inside (constituting the framework of the furniture 1), and is composed of a plurality of polygonal plate-shaped (rectangular in plan view in the embodiment) partition plates 20 arranged at appropriate intervals in the vertical direction, and a plurality of vertically long rectangular leg plates 21 attached around the group of partition plates 20. In the embodiment, the partition plates 20 are arranged in three upper and lower rows, and a total of eight leg plates 21 are attached to each of these three rows of partition plates 20, two on each side. In each leg plate 21, inwardly opening slits 23 are formed at appropriate intervals in the vertical direction so as to correspond to the outwardly opening slits 22 formed at the peripheral edge of the partition plate 20. By fitting the slits 23 of each leg plate 21 into the slits 22 of each partition plate 20, the core body 4 that becomes the framework of the furniture 1 is assembled.

[0019] In addition to the slits 22 for attaching the leg plates 21, outwardly opening outer vertical cutting grooves 24 are formed in each partition plate 20. The outer vertical cutting grooves 24 of each partition plate 20 are formed between the horizontally arranged slits 22 on one side of each partition plate 20 so as to fit with the inner vertical engaging portions 13, 14 formed on the side horizontal flaps 9 of the half side plates 6, and are arranged in a vertical row in accordance with the arrangement direction of the group of partition plates 20. The outwardly opening outer vertical cutting grooves 24 formed in each partition plate 20 and the inner vertical engaging portions 13, 14 of the side vertical flaps 12 corresponding to the outer vertical cutting grooves 24 of each partition plate 20 form vertical engaging means that are formed on each side vertical flap 12 and the core body 4 and fit with each other in the inner and outer directions.

[0020] In addition to the slits 23 for attaching the partition plates 20, outwardly opening outer horizontal cutting grooves 25 are formed at the upper part of each leg plate 21. The outer horizontal cutting grooves 25 of each leg plate 21 are each side horizontal fl It fits with the inner cut grooves 11 and 19 of the wraps 8 and 9 and the corresponding inner cut grooves 19 of the top horizontal flap 17. An outwardly open outer cut groove 25 formed at the upper part of each foot plate 21 and an inwardly open inner cut groove 11 and 19 of the side horizontal flaps 8 and 9 and the top horizontal flap 17 corresponding to each outer cut groove 25 are formed in each of the side horizontal flaps 8 and 9, the corresponding top horizontal flap 17, and the core body 4 to constitute a horizontal engagement means that fits with each other in the inner and outer directions.

[0021] The outer cut groove 25 at the upper part of each foot plate 21 is formed in a stepped groove shape (see FIGS. 8(b) and 9(b)). As can be seen from FIGS. 8(b) and 9(b), the lower part 25a of the outer cut groove 25 into which the inner cut groove 11 of the side horizontal flaps 8 and 9 fits is deeper than the upper part 25b into which the inner cut groove 19 of the top horizontal flap 17 fits. That is, the groove depth Da of the lower part 25a is deeper than the groove depth Db of the upper part 25b.

[0022] At the upper inner corner part of each foot plate 21, a notch 27 is formed into which the corner part of a rectangular reinforcing plate 26 for supporting the top plate 15 of the top cover body 3 from below fits in plan view. The top plate 15 of the top cover body 3 is placed on the reinforcing plate 26 fitted into the notches 27, and the reinforcing plate 26 complements the strength of the top plate 15. In the partition plates 20 other than the lowermost one, through holes 28 for thinning are formed. The lowermost partition plate 20 has no through hole 28 and is in the shape of a rectangular plate in plan view. This is to enable a weight for preventing the wobbling of the furniture 1 to be placed on the lowermost partition plate 20.

[0023] Next, with reference to FIGS. 7 to 10, the assembly procedure of the furniture 1 will be described. First, as shown in FIG. 7, the partition plate 20 groups and the foot plate 21 groups are fitted to each other, and the reinforcing plate 26 is fitted into the notch 27 at the upper end of the foot plate 21 groups to assemble the core body 4. Next, the lid body 3 in the unfolded state is placed on the reinforcing plate 26, and each top side plate 16 is bent downward along the horizontal folding line 18a, and each top horizontal flap 17 is bent inward along the horizontal folding line 18b while fitting the outer horizontal cutout groove 25 on the corresponding foot plate 21 side and the inner horizontal cutout groove 19 of the top horizontal flap 17 together (see FIGS. 8(a) and (b)).

[0024] Next, while surrounding the core body 4 to form a rectangular tube shape, each side plate 5 of the side wall body 2 in the unfolded state is bent inward along each vertical folding line 7a, and each side horizontal flap 8 is bent inward along the horizontal folding line 10 while fitting the outer horizontal cutout groove 25 of the corresponding foot plate 21 and the inner horizontal cutout groove 11 of the side horizontal flap 8 together (see FIGS. 9(a) and (b)). At this time, the corresponding top horizontal flap 17 is guided and pushed up by the side horizontal flap 8, the inner horizontal cutout groove 19 of the top horizontal flap 17 is fitted into the upper part 25b of the outer horizontal cutout groove 25, and the inner horizontal cutout groove 11 of the side horizontal flap 8 is fitted into the lower part 25a of the outer horizontal cutout groove 25. Therefore, each side horizontal flap 8 and the corresponding top horizontal flap 17 function as an overlap margin. Each side horizontal flap 8 and the corresponding top horizontal flap 17 overlap vertically in a state where the horizontal engagement means (outer horizontal cutout groove 25 and inner horizontal cutout grooves 11, 19) are fitted together.

[0025] Then, while bending each half side plate 6 of the side wall body 2 in the unfolded state inward along each vertical fold line 7b and bending each side horizontal flap 9 inward along the horizontal fold line 10, the outer horizontal cut groove 25 of the corresponding foot plate 21 and the inner horizontal cut groove 11 of the side horizontal flap 9 are fitted together. Also at this time, the corresponding top horizontal flap 17 is guided and pushed up by the side horizontal flap 9, and the inner horizontal cut groove 19 of the top horizontal flap 17 fits into the upper part 25b of the outer horizontal cut groove 25, and the inner horizontal cut groove 11 of the side horizontal flap 9 fits into the lower part 25a of the outer horizontal cut groove 25. Therefore, each side horizontal flap 9 and the corresponding top horizontal flap 17 also function as an overlap margin. The side horizontal flap 9 and the corresponding top horizontal flap 17 overlap vertically in a state where the horizontal engagement means (outer horizontal cut groove 25 and inner horizontal cut grooves 11, 19) are fitted together.

[0026] And in accordance with the fitting together of the outer horizontal cut groove 25 of the corresponding foot plate 21 and the inner horizontal cut groove 11 of the side horizontal flap 9, the opposing side vertical flaps 12 are bent inward along each vertical fold line 7c so as to overlap each other, and the inclined side portions 13 and the respective inner vertical cut grooves 14 that match by the overlapping of the both-side vertical flaps 12 are fitted into the outer vertical cut grooves 24 of the corresponding partition plate 20 (see FIG. 10). With the above, the assembly of the furniture 1 shown in FIG. 1, that is, the furniture 1 having a quadrangular prism shape on the outer shape, is completed. The opposing side vertical flaps 12 also function as an overlap margin. It is also possible to attach the top cover body 3 after attaching the side wall body 2 to the core body 4.

[0027] The side horizontal flaps 8, 9, the top horizontal flap 17, and the side vertical flaps 12 will all enter the interior of the furniture 1. Between each side plate 5, 6 (including the half side plate 6) of the side wall body 2 and the top side plate 16 of the corresponding top cover body 3, there is a joining portion (the joining portion between the side wall body 2 and the top cover body 3) where the side horizontal flaps 8, 9 and the top horizontal flap 17 enter, but they are configured in the same planar shape. There is also a joining portion between the pair of half side plates 6, but the half side plates 6 are also configured in the same planar shape with respect to each other.

[0028] According to the above configuration, since each side horizontal flap 8, 9 and the corresponding top horizontal flap 17 overlap vertically with the horizontal engagement means (outer horizontal cut groove 25 and inner horizontal cut grooves 11, 19) fitted together, even if the lid body 3 is about to warp (deform) under the influence of weather and humidity, each top horizontal flap 17 of the lid body 3 will catch on the core body 4 (each foot plate 21) via the horizontal engagement means (outer horizontal cut groove 25 and inner horizontal cut grooves 11, 19), and the deformation of the lid body 3 will be suppressed. For this reason, it becomes difficult for a large gap to form at the joint portion between the lid body 3 and the side wall body 2 (the joint portion between the side plates 5, 6 and the top side plates 16), making the joint portion less noticeable and enabling a sense of unity between the lid body 3 and the side wall body 2 to be achieved. As a result, the appearance (design) of the furniture 1 as a whole is also improved.

[0029] As shown in FIGS. 8(b) and 9(b), in the embodiment, since the width Wa in the short side direction of the side horizontal flaps 8, 9 is longer than the width Wb in the short side direction of the top horizontal flap 17, the horizontal engagement means (outer horizontal cut groove 25 and inner horizontal cut groove 11) between the side horizontal flaps 8, 9 and the core body 4 are less likely to come off. For this reason, for example, it becomes easier to suppress the detachment of the side wall body 2 due to the influence of gravity. It is also easy to suppress the deformation of the side wall body 2 due to the influence of weather and humidity. The presence of the side horizontal flaps 8, 9 with a long width Wa in the short side direction is also effective in preventing the top horizontal flaps 17 that overlap each other from coming off. It should be noted that it is also possible to configure the width Wa in the short side direction of the side horizontal flaps 8, 9 to be shorter than the width Wb in the short side direction of the top horizontal flap 17 or to have the same length.

[0030] Also, as shown in FIGS. 8(b) and 9(b), the lower portion 25a of the outer cross-cut groove 25 into which the inner cross-cut grooves 11 of the side horizontal flaps 8 and 9 fit is made deeper than the upper portion 25b into which the inner cross-cut groove 19 of the top horizontal flap 17 fits. That is, the groove depth Da of the lower portion 25a is made deeper than the groove depth Db of the upper portion 25b. Even in this configuration, the lateral engagement means (the outer cross-cut groove 25 and the inner cross-cut grooves 11) between the side horizontal flaps 8 and 9 and the core body 4 are less likely to come off, and for example, it becomes easier to suppress the dropping of the side wall body 2 due to the influence of gravity. Of course, it is also easy to suppress the deformation of the side wall body 2 due to the influence of weather and humidity.

[0031] The furniture 1 of the embodiment can be used as various stands, tables, chairs, or objects for display or the like. In this case, the furniture 1 is placed on a tabletop or the floor, such as a table, with the canopy body 3 on top. Needless to say, the outer surfaces of the side plates 5 and half side plates 6 of the side wall body 2 and the top plate 15 and top side plates 16 of the canopy body 3 in the furniture 1 can be decorated by printing or the like. This also effectively contributes to improving the design.

[0032] Furthermore, in the embodiment, the side horizontal flaps 8 and 9 that function as overlapping margins, the top horizontal flap 17, and the side vertical flaps 12 may be adhered with an adhesive, tape, or the like. However, if the configuration of the embodiment is adopted, the furniture 1 can be repeatedly assembled and disassembled, and the workability is extremely good, for example, when it is reused or separately discarded.

[0033] By the way, in the furniture 1 of the embodiment, since each side horizontal flap 8 and 9 and the corresponding top horizontal flap 17 are stacked vertically in a state where the lateral engagement means (the outer cross-cut groove 25 and the inner cross-cut grooves 11 and 19) are fitted together, when disassembling the furniture 1, it cannot be removed from the canopy body 3 and will be removed from the side wall body 2. In this regard, in the embodiment, an inclined side portion 13 that is cut out with a gentle gradient with respect to the vertical is formed at the upper part of each side vertical flap 12, and the inclined side portion 13 (inner vertical engagement portion) is inserted into the outermost vertical cut groove 24 at the uppermost stage.

[0034] With such a configuration, when pulling out the lower part of the half-side plate 6 outward to release the engagement of the vertical engagement means (the inner vertical engagement portions 13, 14 and the outer vertical cut groove 24), the inclined side portion 13 does not hit against the uppermost partition plate 20, and the inclined side portion 13 can smoothly come out of the uppermost outer vertical cut groove 24 outward. Therefore, the engagement of the vertical engagement means (the inner vertical engagement portions 13, 14 and the outer vertical cut groove 24) in the side wall body 2 can be smoothly released.

[0035] Note that the configuration of each part in the present invention is not limited to the illustrated embodiment, and various modifications can be made without departing from the gist of the present invention. For example, although the outer shape of the furniture 1 in the embodiment is a quadrangular prism, it is not limited thereto, and it is also possible to have other prismatic outer shapes such as a triangular prism, a pentagonal prism, or a hexagonal prism. Further, in the embodiment, the shape of the top plate 15 of the canopy body 3 is a square, but it is not limited to a regular polygon, and a rhombus, a trapezoid, or other polygonal shapes may be adopted. The inner vertical engagement portion 13 at the upper part of each side vertical flap 12 is an inclined side portion 13, but it is not particularly limited thereto. For example, it may be in the shape of a vertical plate, as long as it can be inserted into the uppermost outer vertical cut groove 24 and does not get caught in the vertical direction. Whether there is a groove in the inner vertical engagement portion 13 at the upper part of each side vertical flap 12 is not necessary, as long as it cannot be displaced vertically with respect to the uppermost outer vertical cut groove 24.
