[0018] [Shelf 1 (First Real Form)] First, a shelf 1 according to a first embodiment of the frame-structured furniture of the present invention will be described with reference to Figures 1 to 7. The shelf 1 described below is mainly constructed by combining steel members. In this specification, the longitudinal direction of shelf 1 in a plan view will be described as the "left-right direction" or "width direction", and the lateral direction will be described as the "front-rear direction" or "depth direction" (the same applies to other embodiments).

[0019] The shelf 1 according to this embodiment is constructed by five shelf members 5 being spanned across a pair of left and right frame members 2. As shown in FIG. 2, each frame member 2 is constructed by connecting the upper ends of two support columns 3.3 arranged in the depth direction with an upper connecting frame 4U, and connecting the lower ends of the support columns 3.3 with a lower connecting frame 4D. The support columns 3.3 are connected at their vertical intermediate parts with four middle connecting frames 4M. The support columns 3.3 are joined to the upper, middle and lower connecting frames 4U, 4M and 4D by welding. An engagement hole 3a is opened on the inner side surface in the left and right direction of each support column 3 at the height position where each connecting frame 4 is provided, for engaging with a connecting metal fitting 7 described later (see FIG. 6).

[0020] In this embodiment, the shelf member 5 according to the first example is made of a steel metal plate and is spanned between the frame members 2 and 2. More specifically, as shown in Figures 2 and 3(a), the frame members 2 and 2 are firmly connected to the shelf member 5 via connecting metal fittings 7, thereby forming a highly rigid shelf 1.

[0021] In the shelf 1 according to this embodiment, the uppermost parts of the frame members 2 and 2 are connected to horizontal frames 8 and 8 via connecting fittings 7. The method of connecting the horizontal frame 8 to the support posts 3 is similar to the method of connecting the shelf members 5 to the support posts 3, so a detailed explanation will be omitted. Also, it is possible to configure the shelf 1 without providing the horizontal frame 8 at the uppermost part, and to connect the upper ends of the frame members 2 and 2 to the shelf members 5.

[0022] As described above, in the shelf 1 according to this embodiment, the frame member 2 is formed by the four support pillars 3 arranged in a row in the depth and width directions, and the upper, middle, and lower connecting frames 4U, 4M, and 4D that connect the upper and lower ends of the support pillars 3 in the front-to-rear direction. The shelf 1 is further composed of a pair of left and right frame members 2 / 2, five shelf members 5 that are bridged between the frame members 2 / 2 (between the four support pillars 3), and two horizontal frames 8 / 8.

[0023] As shown in Figures 3(a) and 3(b), the shelf member 5 has a total of four metal fitting accommodating portions 5b formed at both ends in the width direction of both sides (front and rear sides) in the depth direction. In this embodiment, the metal fitting accommodating portions 5b are formed by bending the front and rear sides of the shelf member 5. As shown in Figures 6 and 7, fixing holes 5a for fixing the connecting metal fittings 7 are opened in the lower surface of the metal fitting accommodating portions 5b.

[0024] 3 and 4, a reinforcing member 6 made by bending a metal plate along the width direction of the shelf member 5 is fixed near the metal fitting receiving portion 5b. The reinforcing member 6 can improve the strength of the shelf member 5. It is possible to configure the shelf member 5 without providing the reinforcing member 6 by forming the shelf member 5 from a material with sufficiently high rigidity.

[0025] 7, a base end of a connecting fitting 7 is fixed to the fitting receiving portion 5b. Then, a tip end of the connecting fitting 7 (an engagement portion 72a of a second fitting 72 described later) engages with an engagement hole 3a of the support post 3, thereby assembling the support post 3 and the shelf member 5 (see FIG. 6).

[0026] 5 to 7, the connecting fitting 7 is composed of a first fitting 71 and a second fitting 72. A slide portion 71a is formed to protrude from the side surface of the first fitting 71. A female threaded hole 71b is opened in the bottom surface of the first fitting 71. The first fitting 71 is fixed to the fitting receiving portion 5b by inserting a screw S through a fixing hole 5a opened in the shelf member 5 and screwing it into the female threaded hole 71b.

[0027] The second fitting 72 has an engagement portion 72a formed at its tip, which engages with an engagement hole 3a of the support 3. In addition, an inclined groove portion 72b into which the slide portion 71a of the first fitting 71 can be inserted is formed on the side surface of the second fitting 72. An oval-shaped insertion hole 72c is opened in the bottom surface of the second fitting 72.

[0028] When connecting the support 3 and the shelf member 5 with the connecting fitting 7, the slide portion 71a is inserted into the inclined groove portion 72b to combine the first fitting 71 and the second fitting 72, and the engagement portion 72a is engaged with the engagement hole 3a. Then, the connecting fitting 7 is inserted into the fitting accommodating portion 5b of the shelf member 5, and as shown in Fig. 7(a), a screw S is inserted through the fixing hole 5a and the insertion hole 72c and screwed into the female threaded hole 71b.

[0029] Tightening the screw S brings the first metal fitting 71 and the second metal fitting 72 closer to each other, causing the slide portion 71a to slide downward along the inclined groove portion 72b. As a result, the first metal fitting 71 and the second metal fitting 72 are displaced relative to each other in a direction in which the base end and the tip end of the connecting metal fitting 7 approach each other, so that the shelf member 5 and the support 3 are drawn to each other and firmly connected, as shown in Fig. 7(b).

[0030] As described above, in shelf 1 according to the first embodiment of the frame-constructed furniture of the present invention, metal fitting receiving portions 5b are formed on both widthwise ends of both depthwise sides of shelf member 5. Then, the base ends of connecting fittings 7 are fixed to metal fitting receiving portions 5b, and the tip ends of connecting fittings 7 engage with the posts 3, thereby assembling frame members 2·2 (four posts 3) and shelf member 5.

[0031] In this way, the shelf 1 according to this embodiment is configured so that the shelf member 5 is directly attached to the frame member 2 (support 3), and there is no need to bridge a horizontal frame between the supports 3-3 in order to assemble the shelf member 5. In other words, the number of steps and parts required in manufacturing the shelf 1 can be reduced, thereby suppressing the manufacturing costs of the shelf 1. Also, in this embodiment, by bridging the shelf member 5 across a pair of frame members 2-2, it is possible to increase the rigidity of the shelf 1.

[0032] Furthermore, according to the shelf 1 of this embodiment, the shape in plan view at a predetermined height can be stabilized to the shape of the shelf member 5. That is, at the height position where the shelf member 5 is provided, the horizontal positions of the front and rear parts of the shelf 1 can be made to coincide, and deformation of the shelf 1 into a parallelogram shape in plan view can be suppressed, thereby improving the strength of the shelf 1.

[0033] In addition, in the shelf 1 according to this embodiment, the shelf member 5 is made of a metal plate, and the metal fitting accommodating portion 5b is formed by bending both sides in the depth direction of the shelf member 5. This makes it possible to form the metal fitting accommodating portion 5b with an inexpensive and high-strength structure.

[0034] [Other Examples of Shelf Members] Next, a shelf member 15 according to a second embodiment that can be used in place of the shelf member 5 according to the first embodiment in the shelf 1 according to this embodiment will be described with reference to Figures 8 and 9. As shown in Figures 8 and 9, the shelf member 15 is configured by connecting a wooden board 15w, which is a plate-like member, to a metal plate member 15s, which is attached to the lower surface of the wooden board 15w, with screws.

[0035] 8(a) and (b), the shelf member 15 has a total of four metal fitting accommodating portions 15b formed at both ends in the width direction of both sides in the depth direction (front side and rear side). Similar to the shelf member 5, the connecting metal fittings 7 are inserted into the metal fitting accommodating portions 15b, and the shelf member 15 is connected to the support 3 via the connecting metal fittings 7.

[0036] In this embodiment, the metal fitting accommodating portion 15b is formed by bending the front and rear edges of a metal plate member 15s that constitutes the shelf member 15. More specifically, the metal plate member 15s is configured to have edges along both edges in the depth direction of the wooden board 15w, and the metal fitting accommodating portion 15b is formed by bending the edges of the metal plate member 15s.

[0037] Next, a shelf member 25 according to a third embodiment that can be used in place of the shelf member 5 according to the first embodiment in the shelf 1 according to this embodiment will be described with reference to Figures 10 and 11. As shown in Figures 10 and 11, shelf member 25 is formed by connecting, with screws, a wooden board 25w, which is a single plate-like member, and two metal plate members 25s, 25s attached to the underside of both sides (front and rear sides) of wooden board 25w in the depth direction.

[0038] 10(a) and (b), shelf member 25 has a total of four metal fitting accommodating portions 25b formed at both ends in the width direction of both sides in the depth direction (front side and rear side). Similar to shelf member 5, connecting metal fittings 7 are inserted into metal fitting accommodating portions 25b, and shelf member 25 is connected to support posts 3 via connecting metal fittings 7.

[0039] In this embodiment, the metal fitting accommodating portion 25b is formed by bending the front edge of the front metal plate member 25s and the rear edge of the rear metal plate member 25s that constitute the shelf member 25. More specifically, each of the metal plate members 25s is configured to have edges along both sides in the depth direction of the wooden board 25w, and the metal fitting accommodating portion 25b is formed by bending the edges of the metal plate member 25s.

[0040] By combining a wooden board and a metal plate member as in the shelf members 15 and 25 according to the second and third embodiments, it is possible to form a metal fitting receiving section with a low cost and high strength structure. In addition, since the surface of the wooden board is exposed on the top surface of the shelf members in the above embodiments, it is possible to improve the design of the shelf 1. In addition to wooden boards, resin plates, glass plates, gypsum boards, steel plates provided with reinforcing materials, etc. can be used as the plate-like members in the above embodiments. In this case, it is also possible to reverse the top and bottom surfaces of the shelf member and configure it so that the plate-like member is located on the lower side.

[0041] [Shelf 101 (second embodiment)] Next, a shelf 101 according to a second embodiment of the frame-structured furniture of the present invention will be described with reference to Figures 12 and 13. In the embodiment described below, detailed descriptions of the same configuration as the shelf 1 according to the first embodiment will be omitted, and different parts will be mainly described.

[0042] The shelf 101 according to this embodiment is configured by spanning five shelf members 105 across a pair of left and right frame members 102. Each frame member 102 has two support columns 103 arranged in the depth direction, which are connected by an upper connecting frame 104U, a lower connecting frame 104D, and four middle connecting frames 104M.

[0043] In the shelf 101 according to this embodiment, the shelf member 105 is made of a steel metal plate and is connected to the posts 103 of the frame members 102 via connecting metal fittings in the same manner as in the first embodiment. In addition, horizontal frames 108 are provided on the top of the frame members 102.

[0044] The shelf 101 according to this embodiment is provided with a back panel Pb that closes the rear side of the upper space of each shelf member 105, and side panels Ps-Ps that close both the left and right sides of the upper space of the shelf member 105. The method of assembling the back panel Pb will be described below. The method of assembling the side panels Ps is substantially the same as that of the back panel Pb.

[0045] 13, in the shelf 101 according to this embodiment, the back panel Pb is assembled via a lower fixture 111 and an upper fixture 112. The lower fixture 111 is a metal plate bent into a crank shape in a plan view, and the upper fixture 112 is a rectangular metal plate. The upper fixture 112 is inserted into a groove G formed on the top surface of the back panel Pb.

[0046] 13, in this embodiment, the support 103 has a support slit 103a into which the base end of the lower fixing device 111 can be inserted. In addition, the bottom surface of the shelf member 105 has a shelf slit 105a into which the upper fixing device 112 can be inserted.

[0047] When assembling the back panel Pb to the shelf 101, the upper side of the upper fixing tool 112 inserted into the groove G of the back panel Pb is inserted into the shelf slit 105a of the shelf member 105. Then, the lower part of the back panel Pb is abutted against the lower fixing tool 111 inserted into the support slit 103a, and the lower fixing tool 111 and the back panel Pb are joined by screws.

[0048] As shown in FIG. 13, in the present embodiment, a frame slit 104a into which an upper fixture 112 can be inserted is formed on the lower surface of the middle connecting frame 104M (the same applies to the upper connecting frame 104U).

[0049] When assembling the side panel Ps to the shelf 101, the upper side of the upper fastener 112 inserted into the groove G of the side panel Ps is inserted into the frame slit 104a of the middle connecting frame 104M. Then, the lower part of the side panel Ps is abutted against the lower fastener 111 inserted into the support slit 103a, and the lower fastener 111 and the side panel Ps are joined by screws.

[0050] As described above, in the shelf 101 according to the second embodiment of the frame-structured furniture of the present invention, slits are formed in the support posts 103, the connecting frame 104, and the shelf members 105, making it possible to assemble the back panel Pb and the side panels Ps·Ps.

[0051] [Shelf 201 (third embodiment)] Next, a shelf 201 according to a third embodiment of the frame-structured furniture of the present invention will be described with reference to Figs. 14 to 16. The shelf 201 according to this embodiment is configured by five shelf members 205 being spanned across a pair of left and right frame members 202. Each frame member 202 has two support posts 203 arranged in the depth direction, which are connected by an upper connecting frame 204U and a lower connecting frame 204D. In other words, the shelf 201 according to this embodiment has a configuration in which the middle connecting frame 4M is omitted from the shelf 1 according to the first embodiment.

[0052] In the shelf 201 according to this embodiment, the shelf member 205 is made of a steel metal plate and is connected to the posts 203 of the frame members 202 via connecting metal fittings in the same manner as in the first embodiment. In addition, horizontal frames 208 are provided on the top of the frame members 202.

[0053] 15(a) and 15(b), the shelf member 205 has a total of four metal fitting accommodating portions 205b formed at both ends in the width direction of both sides (front and rear sides) in the depth direction. In this embodiment, the metal fitting accommodating portions 205b are formed by bending the front and rear sides of the shelf member 205. As shown in Figs. 15 and 16, reinforcing members 206 formed by bending a metal plate along the width direction of the shelf member 205 are fixed near the metal fitting accommodating portions 205b.

[0054] As shown in Fig. 15(a) and (b), in the shelf 201 according to this embodiment, both left and right side surfaces of the shelf member 205 are formed to protrude so as to be flush with the outer surfaces of the support posts 203 in the left and right direction. As a result, both left and right ends of the shelf member 205 are inserted between the support posts 203, so that the support posts 203 and the shelf member 205 are positioned on the same plane on the side surface of the shelf 201, improving the design of the shelf 201. Even when multiple shelves 201 are arranged side by side, no gaps are formed between the adjacent shelf members 205, so that the design can be prevented from being deteriorated. The shelf member 5 in the first embodiment is provided at the bottom of the shelf 201 according to this embodiment to prevent interference with the lower connecting frame 204D.

[0055] It is also possible to provide the frame members 202 / 202 employed in this embodiment with shelf members that combine plate-like members and metal plate members, such as the shelf members 15 / 25 according to the second and third examples of the first embodiment. Even in this case, the design of the shelf can be improved by forming both the left and right side surfaces of the shelf member to protrude so as to be flush with the outer surfaces in the left and right direction of the support 203.

[0056] [Shelf 301 (fourth embodiment)] Next, a shelf 301 according to a fourth embodiment of the frame-structured furniture of the present invention will be described with reference to Fig. 17.

Each frame member 302 has two support posts 303 arranged in the depth direction, which are connected by an upper connecting frame 304U and a lower connecting frame 304D. In other words, the shelf 301 according to this embodiment is configured by lining up two shelves 201 according to the third embodiment, sharing a central frame member 302, and connecting them with shelf members 305.

[0057] As shown in Fig. 17, in shelf 301 according to this embodiment, both left and right side surfaces of shelf member 305 are formed to protrude by a length half the left and right width of support post 303. As a result, both left and right ends of shelf member 305 are inserted up to half the left and right width of support post 303. Therefore, as shown in Fig. 17, no gap is formed between adjacent shelf members 305, which prevents a decrease in the design of shelf 301. Note that the shelf member 5 in the first embodiment is provided at the bottom of shelf 301 according to this embodiment to prevent interference with lower connecting frame 304D.

[0058] [Other variations] The above embodiment can be modified as appropriate as shown in the other modified examples shown below. Each modified example described in this specification may be applied in combination with other modified examples to the extent that no contradiction occurs.

[0059] In the shelves according to each of the above embodiments, the posts are connected with a connecting frame to form a frame member, and multiple frame members are connected with shelf members, but it is also possible to connect each post with a shelf member without connecting the posts with a connecting frame (without forming a frame member).

[0060] Furthermore, even when pillars are connected with connecting frames to form a frame member, the arrangement shape and number of connecting frames are not limited, and it is possible to form a frame member by connecting any of the upper ends, lower ends, or middle parts of the pillars.
