[0026] Next, specific embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing a state in which a table leg 1 according to an embodiment of the present invention is used, showing an example in which a table 3 is formed by holding a table top 2 with a plurality of table legs 1. Various tables 3 can be formed using the table legs 1 of this embodiment, and Fig. 1 shows one example. The table 3 can be used for any purpose, but due to its high designability, it is suitable for use, for example, in business negotiations and exhibitions in various stores. It can also be used at home as a living room table, etc.

[0027] The table 3 in the illustrated example is configured with a tabletop 2 held on the tops of four table legs 1. The table legs 1 typically have the same configuration as each other and are arranged vertically. The tabletop 2 is formed from a substantially rectangular plate material, for example, transparent tempered glass. The tabletop 2 is placed on the tops of the table legs 1 and held horizontally.

[0028] In a plan view of the table 3 seen from above, the table legs 1 are arranged at the four corners of the roughly rectangular tabletop 2. The table legs 1 are connected to each other via connecting materials 4. In this case, the connecting materials 4 may be connected to each other via bonding materials 5 that also serve as decoration. In the illustrated example, the bonding material 5 is provided in the center of the table 3 in a plan view, and the bonding material 5 and each table leg 1 are connected by the connecting materials 4 below the tabletop 2.

[0029] In any case, the table legs 1 are connected to each other via the connecting members 4 to prevent the table from tipping over. The table top 2 is placed on and supported by the upper part of the upright table legs 1. A non-slip material (e.g., a rubber-like sheet material) may be provided between the upper surface of the table leg 1 and the table top 2. The table top 2 may simply be placed on the table leg 1, or may be fixed by adhesion (or other means) as desired.

[0030] The table leg 1 of this embodiment will now be described in further detail. Fig. 2 is a perspective view showing the main part of the table leg 1 of this embodiment. Fig. 3 is an enlarged view of the upper part of Fig. 2. However, in Fig. 3, the upper part of Fig. 2 is shown rotated slightly around an axis along the vertical direction. Although Fig. 3 is an enlarged view of the upper part of Fig. 2, the same is true for the lower part of Fig. 2.

[0031] The table leg 1 of this embodiment is composed of a number of detachable members assembled together. The members constituting the table leg 1 can be made of any material, but are typically made of metal. In this embodiment, they are made of stainless steel, for example. The table leg 1 includes, as its main parts, four support members 6 and one or more decorative members 7.

[0032] Each of the support members 6 has the same configuration (shape and size). In this embodiment, each of the support members 6 is a bar with a rectangular cross section. In the illustrated example, each of the support members 6 is a bar with a square cross section. However, the support members 6 may have a rectangular, circular, elliptical, or other shape in cross section. Alternatively, the support members 6 may be bars whose cross section changes depending on the location in the longitudinal direction, or may be curved bars. Also, the support members 6 may be formed from hollow bars (pipes) instead of solid bars.

[0033] The support material 6 is arranged in the vertical direction, and has notches 8 formed at both the top and bottom ends, opening to the side. Specifically, the support material 6 has horizontal notches 8 formed at a position a set dimension below the top end face and a set dimension above the bottom end face, opening to the side. In the illustrated example, the notch 8 is formed opening to one corner of the support material 6, which has a rectangular cross section. At this time, the notch 8 opens continuously to two adjacent side faces out of the four side faces of the support material 6, and the cross section is formed to be approximately fan-shaped.

[0034] In this embodiment, a pair of decorative materials 7 are provided, one above the other. The upper and lower decorative materials 7 can have the same configuration (shape and size), but may be slightly different. In this embodiment, each decorative material 7 is approximately pyramidal. In this case, the upper and lower decorative materials 7 are arranged so that the apexes of the approximately pyramidal pyramids butt against each other. In other words, the lower decorative material 7 is arranged so that the end face (bottom face) 7a of the approximately pyramidal pyramid is arranged downward and the apex faces upward, while the upper decorative material 7 is turned upside down and arranged so that the end face 7a of the approximately pyramidal pyramid is arranged upward and the apex faces downward. The apexes of the upper and lower approximately pyramidal pyramids are arranged facing each other. The apexes of the upper and lower pyramids are abutted against each other, but may be separated depending on the circumstances.

[0035] In the illustrated example, each of the decorative materials 7 is formed from a hollow member having a regular square pyramid shape. Therefore, the end surface 7a of the decorative material 7 is formed in a square frame shape. Then, on each side constituting the end surface 7a, a stopper 9 is provided protruding outward in the vertical direction. That is, the upper decorative material 7 is provided with four stoppers 9 protruding upward from the end surface 7a arranged at the top. On the other hand, the lower decorative material 7 is provided with four stoppers 9 protruding downward from the end surface 7a arranged at the bottom. Each stopper 9 is provided on each side constituting the end surface 7a of the regular square pyramid, and is provided at a predetermined position in the longitudinal direction of each side. Each stopper 9 has the same configuration (shape and size) as the others, and is formed in a substantially L-shape in the illustrated example.

[0036] In Fig. 3, the stopper 9 has a first piece 9a of a substantially rectangular shape extending upward, and a second piece 9b of a substantially rectangular shape connected to one side of the extending tip of the first piece 9a. The first piece 9a and the second piece 9b are integrally formed, and the whole is in a substantially L-shaped plate shape. An engagement groove 9c between the end surface 7a of the decorative material 7 and the second piece 9b of the stopper 9 can fit the tip of a fastener 11 (Fig. 6) described later. When the fastener 11 is rotated, the stopper 9 prevents the fastener 11 from rotating.

[0037] Four support members 6 are provided so as to surround the decorative material 7. That is, the support members 6 are arranged adjacent to each side of the end face 7a of the decorative material 7 having a substantially quadrangular pyramid shape. Each support member 6 is arranged so that the corner on the side where the notch 8 is provided abuts against the center of each side of the end face 7a of the decorative material 7. The engagement groove 9c of the stopper 9 and the notch 8 of the support member 6 are arranged at the same height so as to face each other. In this way, the longitudinal end of the support member 6 is arranged to protrude beyond the end face 7a of the decorative material 7.

[0038] Fig. 4 is an exploded perspective view showing the components of the upper part of the table leg 1 of this embodiment. Fig. 5 is a perspective view showing the base material 10 of the components of Fig. 4, viewed from below. Fig. 6 is a perspective view showing the holding structure of the support material 6 and the decorative material 7 to the base material 10. Fig. 7 is a perspective view showing the state after the components of Fig. 4 have been assembled.

[0039] As shown in FIGS. 4 and 6, a base material 10 is held at the upper end of the support material 6 and the decorative material 7 by fasteners 11, and the fasteners 11 are held by a locking member 12 and a locking member 13.

[0040] As shown in FIG. 5, the base material 10 of this embodiment includes a substantially rectangular plate-like portion 14 and a cylindrical portion 15 that protrudes downward from the center thereof.

[0041] The plate-shaped portion 14 is formed with a post insertion hole 14a through which the end of the post 6 passes, and a stopper insertion hole 14b through which the stopper 9 of the decorative material 7 passes. In the case of FIG. 5, the plate-shaped portion 14 is formed with the post insertion holes 14a at the four corners, and the stopper insertion holes 14b are formed adjacent to each of them. The post insertion holes 14a are formed corresponding to the cross section of the post 6, and the stopper insertion holes 14b are formed corresponding to the size of the upper end face of the stopper 9. The post insertion holes 14a and the stopper insertion holes 14b are formed in the plate-shaped portion 14 so that the upper end of the post 6 and the stopper 9 of the decorative material 7 can pass through them in the state shown in FIG.

[0042] The cylindrical portion 15 is provided so as to protrude downward from the center of the plate-like portion 14. A through hole is formed in the cylindrical portion 15 along the up-down direction, and this through hole is a screw hole 15a. A through hole (reference number omitted) having a slightly larger diameter than the screw hole 15a is formed in the plate-like portion 14 at a position corresponding to the screw hole 15a of the cylindrical portion 15.

[0043] As shown in Figures 4 and 6, the base material 10 is held with the ends of each support material 6 and the stopper 9 of the decorative material 7 protruding upward from the top surface of the plate-like portion 14. At this time, the tubular portion 15 of the base material 10 is inserted into the opening (a hollow hole of a substantially rectangular pyramid) of the end surface 7a of the decorative material 7. The base material 10 is held with the bottom surface of the plate-like portion 14 abutting against the end surface 7a of the decorative material 7. That is, in this embodiment, the end surface 7a of the decorative material 7 functions as a holding portion for the base material 10.

[0044] With the bottom surface of the plate-like portion 14 in contact with the end surface 7a of the decorative material 7, the notch 8 of the support material 6 and the engagement groove 9c of the stopper 9 are exposed above the top surface of the plate-like portion 14. In this state, the support material 6 and the decorative material 7 are held to the base material 10 by the fastener 11.

[0045] In this embodiment, the fastener 11 is formed from a substantially cross-shaped plate material. A through hole 11a is formed in the center of the fastener 11, corresponding to the through hole (the screw hole 15a of the cylindrical portion 15) of the plate-shaped portion 14 of the base material 10. In the illustrated example, each tip of the substantially cross-shaped fastener 11 is formed into a substantially semicircular shape. The thickness (plate thickness) of the fastener 11 approximately corresponds to the height (amount of protrusion from the plate-shaped portion 14) of the notch 8 (and the engagement groove 9c of the stopper 9) protruding upward from the plate-shaped portion 14.

[0046] To hold the support material 6 and the decorative material 7 on the base material 10, the fastener 11 is placed so as to overlap the upper surface of the plate-shaped portion 14 as shown by the two-dot chain line in Fig. 6, and then rotated in one circumferential direction. When the fastener 11 is rotated until it hits the stopper 9 as shown by the solid line, the end of the fastener 11 is inserted into the notch 8 of the support material 6 and into the engagement groove 9c of the stopper 9. In this way, the fastener 11 is engaged with the notch 8 and the stopper 9, and the support material 6 and the decorative material 7 can be held on the base material 10. At this time, the base material 10 is held by being sandwiched between the end surface 7a of the decorative material 7 and the fastener 11.

[0047] The notch 8 is generally fan-shaped in plan view, and the arcuate portions of the generally fan-shaped portion are preferably arranged on a common circumference (i.e., on one circle) in plan view (viewed from directly above) when the four struts 6 are arranged as shown in FIG. 6. The outer diameter of the fastener 11 (the distance between the opposing tips) is set in accordance with the diameter of this common circle. This makes it possible to prevent the fastener 11 from wobbling on the plate surface of the plate-like portion 14 when the fastener 11 is engaged with the notch 8 of the strut 6 or the engagement groove 9c of the stopper 9. Specifically, in the solid line state of FIG. 6, when viewed from the diagonal position of the plate-like portion 14, the gap between the tip of the fastener 11 and the outer circumferential surface of the notch 8 (the generally fan-shaped arcuate portion) is preferably set to 1 mm or less.

[0048] Thereafter, as shown in FIG. 4, the detent material 12 is superimposed on the base material 10. The detent material 12 is formed from a substantially rectangular plate material having a size corresponding to the plate-like portion 14 of the base material 10, and a through hole 12a of a set shape is formed therein. The shape of the through hole 12a substantially corresponds to the state in which each member (the support member 6, the stopper 9, and the fastener 11) protruding upward from the plate-like portion 14 is punched out in the solid line state in FIG. 6. Therefore, by superimposing the detent material 12 on the plate-like portion 14 of the base material 10, it is possible to restrict the movement of the fastener 11 in the rotational direction. The thickness (plate thickness) of the detent material 12 substantially corresponds to the thickness of the fastener 11.

[0049] When the detent member 12 is placed on the plate-shaped portion 14, the upper ends of the support member 6 and the stopper 9 protrude slightly upward from the detent member 12. The detent member 13 has through holes 13a and 13b at positions corresponding to these protrusions. That is, the detent member 13 is formed from a substantially rectangular plate material having a size corresponding to the detent member 12, and a substantially square through hole 13a is formed at each of the four corners, while a substantially rectangular through hole 13b is formed adjacent to the square through hole 13a. The upper end of the support member 6 is fitted into the substantially square through hole 13a, and the upper end of the stopper 9 is fitted into the substantially rectangular through hole 13b, so that the detent member 13 is placed on the detent member 12. The detent member 12 and the detent member 13 also have through holes 12a and 13c formed in the center. As shown in FIG. 7, when the return prevention member 12 and the retaining member 13 are overlapped on the plate-shaped portion 14 of the base member 10 , the support member 6 and the stopper 9 do not protrude from the upper surface of the retaining member 13 .

[0050] Fig. 8 is a perspective view showing a state in which a skirt member 16 is fitted onto the upper part of Fig. 7. Also, Fig. 9 is a perspective view showing a state in which the skirt member 16 is viewed from below.

[0051] The skirt member 16 in this embodiment has an upper portion formed as a shallow box-shaped portion 16a having a generally rectangular shape and opening downward. One side wall of the box-shaped portion 16a extends downward to form a connecting wall 16b with the connecting member 4 (FIG. 1). In addition, both side walls of the box-shaped portion 16a that sandwich the connecting wall 16b also extend downward to form reinforcing walls 16c. The reinforcing walls 16c are formed to extend downward as they approach the connecting wall 16b.

[0052] The skirt member 16 has a through hole 16e formed in the center of the upper wall 16d, while the connecting wall 16b serves as an attachment portion for the connecting material 4 (FIG. 1). There is no particular limitation on the configuration of the connecting wall 16b as long as it can connect the connecting material 4. The connecting wall 16b and the connecting material 4 may be fixed by welding or the like, but are preferably connected in a detachable manner. In this embodiment, the connecting material 4 is detachably provided on the connecting wall 16b as follows.

[0053] That is, a plurality of holes 16f each having a substantially rectangular shape are formed in the connecting wall 16b. The end of the connecting member 4 described in FIG. 1 is engaged with the hole 16f. For example, although not shown, a plate material (vertical plate) is fixed to the end of the connecting member 4, and a plurality of hooks each having a substantially L-shape are provided on the plate material. The hooks are then hooked into the holes 16f of the connecting wall 16b, so that the connecting member 4 can be detachably connected to the connecting wall 16b. One end of the connecting member 4 in the longitudinal direction is detachably connected to the skirt member 16, while the other end is detachably connected to the joining member 5.

[0054] The box-shaped portion 16a of the skirt member 16 shown in Fig. 9 is fitted into the upper end portion shown in Fig. 7. As a result, the skirt member 16 is held at the upper end portion of the support member 6 as shown in Fig. 8. Although details will be described later, a fastening member 17 as shown in Fig. 11 is provided on the upper portion of the skirt member 16.

[0055] Fig. 10 is a cross-sectional view showing the assembled state of the upper part of the table leg 1 of this embodiment, and Fig. 11 is a perspective view showing the fastening member 17. As shown in these figures, the fastening member 17 comprises a substantially cylindrical tubular portion 18 and a bolt portion 19 extending downward from the lower part of the tubular portion 18. Also, a screw hole 18a is formed in the upper part of the tubular portion 18, penetrating vertically.

[0056] The bolt portion 19 of the fastening member 17 is screwed into the screw hole 15a of the base member 10 via the through holes 16e, 13c, and 11a of the skirt member 16, the retaining member 13, and the fastener 11. The bolt portion 19 of the fastening member 17 is screwed into the base member 10 until the lower end face of the tubular portion 18 of the fastening member 17 abuts against the skirt member 16. This allows the skirt member 16, the retaining member 13, and the return stopper member 12 to be fastened and fixed to the base member 10.

[0057] A height adjustment member 20 is provided in the screw hole 18a above the fastening member 17. The height adjustment member 20 includes a disk-shaped base portion 20a and a bolt portion 20b protruding downward from the base portion 20a. The bolt portion 20b is screwed into the screw hole 18a of the fastening member 17 so as to be movable forward and backward. By adjusting the amount that the bolt portion 20b is screwed into the fastening member 17, the height of the top plate 2 of the table 3 can be adjusted.

[0058] 12 to 14 are diagrams showing the lower part of the table leg 1 of this embodiment, with FIG. 12 being a perspective view in an assembled state, FIG. 13 being an exploded perspective view, and FIG. 14 being a cross-sectional view in an assembled state. Up to this point, the upper part of the table leg 1 has been described, but the same is true for the lower part of the table leg 1. In other words, it is basically configured upside down. Below, the differences between the two will be mainly described, and explanations of similar parts will be omitted. Also, parts corresponding to the upper part will be described with the same reference numerals.

[0059] A base material 10 is provided at the lower end of the support material 6. The base material 10 comprises a plate-like portion 14 and a tubular portion 15, and the hollow hole of the tubular portion 15 is a screw hole 15a. The base material 10 is arranged with the tubular portion 15 facing upward from the plate-like portion 14, and the lower end of the support material 6 and the stopper 9 of the decorative material 7 are passed through the through holes (support material insertion hole 14a, stopper insertion hole 14b) of the plate-like portion 14 and protrude downward.

[0060] Then, with the fastener 11 overlapped on the plate-like portion 14, it is rotated in one circumferential direction, so that each tip of the approximately cross-shaped fastener 11 can engage with the notch 8 of the support material 6 and the engagement groove 9c of the stopper 9. After that, the return stopper material 12 is overlapped on the plate-like portion 14, and further the slip-out stopper material 13 is overlapped. Then, the fastening material 17 is provided so as to maintain this state. It is not necessary to provide a skirt member 16 at the lower end of the table leg 1.

[0061] The fastening member 17 has a bolt portion 19 protruding upward from the cylindrical portion 18, and the bolt portion 19 is screwed into the screw hole 15a of the base material 10 through the through holes 13c, 11a of the retaining member 13 and the fastener 11. The fastening member 17 has the bolt portion 19 screwed into the screw hole 15a of the base material 10 so as to press the cylindrical portion 18 against the base material 10 through the retaining member 13 and the detent member 12. This allows the fastener 11, the detent member 12, and the retaining member 13 to be held by the base material 10. A screw hole 18a is formed in the lower portion of the cylindrical portion 18, and the height can be adjusted by moving the bolt portion 20b of the height adjustment member 20 forward and backward relative to the screw hole 18a.

[0062] As explained with reference to Fig. 1, the table legs 1 configured as described above are connected to each other via connecting members 4 etc., and then the table top 2 is placed on the upper part (the base portion 20a of the height adjustment member 20). Height adjustment can be performed using the height adjustment members 20 provided above and below the table legs 1. Since the joining member 5 and the table legs 1 are connected via the connecting members 4, the connecting wall 16b of the skirt member 16 is disposed facing towards the inside of the table 3 (Fig. 1).

[0063] According to the table leg 1 of this embodiment, by overlapping the fasteners 11 on the plate-shaped portion 14 of the base material 10 and rotating it while the ends of the support members 6 and the stoppers 9 of the decorative members 7 are protruding from the base member 10, the fasteners 11 can be engaged all at once with the notches 8 of the support members 6 and the stoppers 9 of the decorative members 7. Then, a detent member 12 and a stopper member 13 are provided to maintain the state in which the fasteners 11 are engaged with the notches 8 of the support members 6 and the stoppers 9 of the decorative members 7, and these members are held to the base member 10 by a fastening member 17 that is screwed into the base member 10. Furthermore, a height adjustment member 20 is provided on the fastening member 17 so as to be movable forward and backward, if desired.

[0064] In this way, the support materials 6, decorative materials 7, etc. can be easily provided on the base material 10 without using welding. The design of the table leg 1 can be improved by using a plurality of support materials 6 and decorative materials 7. Since welding is not used in assembling the table leg 1, it is also easy to disassemble. Therefore, the design of the table leg 1 can be easily changed by changing the support materials 6 and / or decorative materials 7.

[0065] The table leg 1 of the present invention is not limited to the configuration of the above embodiment and can be modified as appropriate. In particular, as long as the table leg 1 holds the top plate 2 of the table 3 and includes (a) a plurality of support members 6 each having a notch 8 formed at an end in the longitudinal direction that opens to the side, (b) a base member 10 through which the ends of the plurality of support members 6 pass, and (c) a fastener 11 that is engaged collectively with the notches 8 of the plurality of support members 6 by rotation relative to the base member 10, other configurations can be modified as appropriate.

[0066] For example, in the above embodiment, the table leg 1 has four support members 6, but the number of support members 6 can be changed to two or more. When the support members 6 are arranged at equal intervals in the circumferential direction of the plate-like portion 14 in a plan view of the base member 10, the fastener 11 may have engagement pieces extending from the central portion where the through holes 11a are formed to the notches 8 or the like at equal intervals in the circumferential direction in accordance with the number of support members 6.

[0067] In the above embodiment, the decorative material 7 is made of two pyramidal members with their tops butted together, but the shape and number of the decorative material 7 can be changed. For example, the decorative material 7 may be made of a single rod. In this case, the rod is provided with the base material 10 at both the top and bottom ends.

[0068] In the above embodiment, the base material 10 is held by the end surface 7a of the decorative material 7 with the end of the support material 6 protruding from the plate-like portion 14 of the base material 10, but the base material 10 may be held by another holding portion. For example, a protrusion may be provided on the support material 6, and part of the base material 10 may be abutted against the protrusion to determine position. In that case, the installation of the decorative material 7 may be omitted.

[0069] In addition, in the above embodiment, the skirt member 16 is used at the connection between the connecting member 4 and the table leg 1, but the configuration of the skirt member 16 can be changed as appropriate. In some cases, the function of the skirt member 16 can be provided to the fastening member 17 or the like, and the skirt member 16 can be omitted.

[0070] In the above embodiment, the base material 10 is provided on both the upper and lower ends of the support material 6 and is held by the fasteners 11, but such holding may be performed only on one end of the support material 6, either the upper or lower end. In that case, the other end of the support material 6 may be bundled by other means.

[0071] Furthermore, in the above embodiment, the table 3 is configured by supporting the top board 2 with four table legs 1, but the number of table legs 1 that support the top board 2 can be changed as appropriate. The shape of the top board 2 of the table 3 is not limited to a rectangular shape, and may be another shape, such as a circular shape. [Explanation of symbols]
