[0039] First, an embodiment of the corner plate connecting member 10 will be described with reference to Figs. 1 to 3. The corner plate connecting member 10 of this embodiment includes a corner body 11, a first groove 12, a second groove 15, a first convex stripe 20, and a second convex stripe 21. The corner body 11 constitutes the periphery of the first groove 12 and the second groove 15, and is substantially L-shaped when viewed from the front. The first groove 12 and the second groove 15 are arranged on the back side of this corner body 11, and the first convex stripe 20 and the second convex stripe 21 are arranged on the front side. In this embodiment, a plate material b that has been subjected to this processing is used, and the male convex cm of the plate material b is fitted into the first groove 12 and the second groove 15, and the female convex cf of the plate material b is fitted into the first convex stripe 20 and the second convex stripe 21.

[0040] The first groove portion 12 and the second groove portion 15 are provided along the corner body portion 11, which is approximately L-shaped in front view, and are mutually orthogonal grooves, each configured to penetrate from a side surface of the corner body portion 11 to the opposing side surface. The first groove portion 12 and the second groove portion 15 are provided with a first main groove 13 and a second main groove 16, which are configured to be long with the intersection portion 23 as a boundary, and further with a first sub-groove 14 and a second sub-groove 17, which are configured to be short with the intersection portion 23 as a boundary. As shown in FIG. 3(B), these first groove portion 12 and the second groove portion 15 are approximately trapezoidal in side view, and are configured to be wide on the opening side and narrow on the back side. As shown in FIG. 3(C), the side surface of the groove is provided with a reduced width protrusion portion 18, which is a part of the first groove portion 12 and the second groove portion 15 that is reduced in width. This reduced width protrusion portion 18 bites into the male part cm of the plate material b, thereby increasing the connection strength with the plate material b. In this embodiment, the reduced width protrusions 18 are wedge-shaped, and multiple pairs of the wedge-shaped protrusions 18 are arranged in the first main groove 13 and the second main groove 16 so that their tips face each other. In addition, the first sub-groove 14 and the second sub-groove 17 also have reduced width protrusions 18 provided near the intersections 23.

[0041] The first convex stripe portion 20 and the second convex stripe portion 21 are provided on the surface of the square body portion 11 opposite to the first groove portion 12 and the second groove portion 15, i.e., on the front side, and are arranged at positions corresponding to the first main groove 13 and the second main groove 16, respectively. As shown in FIG. 3(B), the first convex stripe portion 20 and the second convex stripe portion 21 are approximately trapezoidal in side view, and are configured to be thick at the base side and thin at the tip side. Also, as shown in FIG. 3(A), the side surface of the convex stripe portion is provided with a widening protrusion portion 22 that is a part of the first convex stripe portion 20 and the second convex stripe portion 21 widened. This widening protrusion portion 22 bites into the female cinches cf of the plate material b, thereby increasing the connection strength with the plate material b. In this embodiment, both ends of the longitudinal direction of the convex stripes 20 and 21 are widened in a wedge shape, and the tips of the wedge shapes are arranged to face each other.

[0042] Next, referring to Fig. 6, a method of assembling plates using the above-mentioned connecting member 10 for square plates will be described. Fig. 6(A) is a front view of the connecting member 10 for square plates, and is a diagram for explaining the state in which the female ribs cf1, cf2 of the plates b1, b2 are fitted into the convex strips 20, 21, and Fig. 6(B) is a rear view, and is a diagram for explaining the state in which the male ribs cm1, cm2 of the plates b1, b2 are fitted into the grooves 12, 15. In this embodiment, two plates b1, b2 are assembled into an L-shape or a T-shape using the connecting member 10 for square plates. In detail, as shown in Fig. 6(B), the male rib cm1 of the first plate b1 of the two plates b1, b2 is fitted into at least the first main groove 13. At this time, when the two plate materials b1, b2 are assembled into an L-shape, the first plate material b1 is fitted only into the first main groove 13 so that the end of the plate material b1 is located midway through the first main groove 13, or the first plate material b1 is fitted into the entire first groove portion 12 so that the end of the plate material b1 is located near the outer end 24 of the first sub-groove 14. On the other hand, when the two plate materials b1, b2 are assembled into a T-shape, the first plate material b1 is fitted into the entire first groove portion 12 and extends beyond the outer end 24 of the first sub-groove 14. Next, the male portion cm2 of the second plate material b2 is fitted into the second main groove 16. Furthermore, as shown in Figure 6 (A), the female indentations cf1, cf2 sides of the plate materials b1, b2 may be fitted such that the female indentation cf1 of the first plate material b1 is fitted into the first convex portion 20, and the female indentation cf2 of the second plate material b2 is fitted into the second convex portion 21.

[0043] In addition, in Fig. 6(A)(B), in order to make the drawings easier to see, the side surface cs of the cut edge of the plate b2 is separated from the wide surface ws of the plate b1, but as shown in Fig. 1, the side surface cs of the cut edge of one plate and the wide surface ws of the other plate can be abutted, or the side surfaces cs of the cut edges of the plates that are butted can be abutted against each other (for example, in Fig. 9(A), the side surface cs1 of the cut edge is abutted against the wide surfaces of the plate b2 and the plate b3, and further the side surface cs2 of the cut edge and the side surface cs3 of the cut edge are abutted against each other.) (The same applies to other embodiments described later.) In addition, in the plate material assembling method of this embodiment, plate materials that have been processed are used, but it is also possible to assemble multiple plate materials using only the first groove portion 12 and the second groove portion 15 of the corner plate connecting member 10 using plate materials with normal cut edges that have not been processed. In such a case, it is also possible to configure the plate material without the first convex rib portion and the second convex rib portion. Conversely, it is also possible to use plate material that has only been processed to have female joints, and to assemble multiple plate materials using only the first ridge portion 20 and the second ridge portion 21 of the corner plate connecting member 10.

[0044] Next, an embodiment of the plate connection member set 1 will be described with reference to Figs. 1 to 5. The plate connection member set 1 of this embodiment includes a corner plate connection member 10 and a reinforcing plate connection member 30.

As shown in Figs. 1, 4, and 5, the reinforcing plate connection member 30 includes a reinforcing body portion 31, a third groove portion 32, a fourth groove portion 33, a third convex strip portion 35, and a fourth convex strip portion 36. The reinforcing body portion 31 constitutes the periphery of the third groove portion 32 and the fourth groove portion 33 and connects the third groove portion 32 and the fourth groove portion 33 at a distance, and is substantially obliquely shaped in front view. The third groove portion 32 and the fourth groove portion 33 are arranged on the back side of this reinforcing body portion 31, and the third convex strip portion 35 and the fourth convex strip portion 36 are arranged on the front side. In this embodiment, a plate material b that has been subjected to this machining is used, and the male prong cm of the plate material b is fitted into the third groove portion 32 and the fourth groove portion 33, and the female prong cf of the plate material b is fitted into the third ridge portion 35 and the fourth ridge portion 36.

[0045] The third groove 32 and the fourth groove 33 are grooves provided near both ends of the reinforcing body 31 having a substantially diagonal oval shape, with their extension lines e1 and e2 perpendicular to each other.

The third plate material b3 is also connected at two points, the third groove portion 32 and the second sub-groove 17. This increases the assembly strength of the plate materials. On the other hand, if the third plate material b3 is not fitted in the second sub-groove 17, the first plate material b1 may be fitted in the entire first groove portion 12, or the second plate material b2 may be fitted in the entire second groove portion 15. Furthermore, as shown in Fig. 9(A), the female indentation cf1 of the first plate material b1 is fitted in the first convex strip portion 20 and the fourth convex strip portion 36, the female indentation cf2 of the second plate material b2 is fitted in the second convex strip portion 21, and the female indentation cf3 of the third plate material b3 is fitted in the third convex strip portion 35.

[0051] Next, an embodiment shown in FIG. 10 will be described. In this embodiment, three plate materials are assembled in a cross shape using the plate connection member set 1. In detail, as shown in FIG. 10(B), the male cone cm1 of the first plate material b1 among the three plate materials b1, b2, and b3 is fitted into all of the first groove portion 12 and the fourth groove portion 33, and is extended from the outer end 24 of the first sub-groove 14.

[0052] Next, an embodiment shown in FIG. 11 will be described. In this embodiment, three plate materials are assembled in a cross shape using a plate connection member set 1. In detail, as shown in FIG. 11(B), among the three plate materials b1, b2, and b3, the male convex cm1 of the first plate material b1 is fitted into all of the first groove portions 12 and the third groove portion 32. Next, the male convex cm2 of the second plate material b2 is fitted into the second main groove 16. Next, the male convex cm3 of the third plate material b3 is fitted into the fourth groove portion 33. Furthermore, as shown in FIG. 11(A), the female convex cf1 of the first plate material b1 is fitted into the first convex portion 20 and the third convex portion 35, the female convex cf2 of the second plate material b2 is fitted into the second convex portion 21, and the female convex cf3 of the third plate material b3 is fitted into the fourth convex portion 36.

[0053] Next, an embodiment shown in Fig. 12 and Fig. 13 will be described. Fig. 12 is a view of the plate connection member set 2 from the front side, and Fig. 13 is a view from the back side. In this embodiment, one corner plate connection member 10 and two reinforcing plate connection members 30a, 30b are used as one plate connection member set 2 to assemble four plate materials in a cross shape. In detail, as shown in Fig. 13, among the four plate materials b1, b2, b3, b4, the male rib cm1 of the first plate material b1 is fitted at least into the first main groove 13 and the fourth groove portion 33a of one reinforcing plate connection member 30a. Next, the male rib cm2 of the second plate material b2 is fitted at least into the second main groove 16 and the third groove portion 32b of the other reinforcing plate connection member 30b. Next, the male prong cm3 of the third plate material b3 is fitted into the third groove portion 32a of one reinforcing plate connecting member 30a and, if necessary, into the second sub-groove 17. Next, the male prong cm4 of the fourth plate material b4 is fitted into the fourth groove portion 33b of the other reinforcing plate connecting member 30b and, if necessary, into the first sub-groove 14. Here, by fitting the male prong cm3 of the third plate material b3 into the second sub-groove 17 as well, or fitting the male prong cm4 of the fourth plate material b4 into the first sub-groove 14, the connection strength of the plate materials can be increased for the same reason as in the embodiment shown in FIG. 9. Alternatively, the first plate material b1 may be fitted into the entire first groove portion 12, or the second plate material b2 may be fitted into the entire second groove portion 15. Furthermore, as shown in Figure 12, the female protrusion cf1 of the first plate material b1 is fitted into the first convex strip portion 20 and the fourth convex strip portion 36a of one of the reinforcing plate connecting members 30a, the female protrusion cf2 of the second plate material b2 is fitted into the second convex strip portion 21 and the third convex strip portion 35b of the other reinforcing plate connecting member 30b, the female protrusion cf3 of the third plate material b3 is fitted into the third convex strip portion 35a of one of the reinforcing plate connecting members 30a, and the female protrusion cf4 of the fourth plate material b4 is fitted into the fourth convex strip portion 36b of the other reinforcing plate connecting member 30b.

[0054] In the plate material assembling method of the above embodiment, plate materials that have been processed are used, but it is also possible to use plate materials with normal cut ends that have not been processed, and assemble multiple plate materials using only the first groove portion 12, the second groove portion 15, the third groove portion 32, and the fourth groove portion 33 of the plate connection member set 1. In such a case, it is also possible to have a configuration that does not include the first convex strip portion, the second convex strip portion, the third convex strip portion, and the fourth convex strip portion. Conversely, it is also possible to use plate materials that have only been processed to have female joints, and assemble multiple plate materials using only the first convex strip portion 20, the second convex strip portion 21, the third convex strip portion 35, and the fourth convex strip portion 36 of the plate connection member set 1.

[0055] Next, the embodiment shown in Fig. 14 will be described. In this embodiment, in addition to the above-mentioned plate assembly method, the male stud cm6 of one plate b6 is fitted into the first groove 12 and the second groove 15 of the square plate connecting member 10, and the female stud cf5 of the other plate b5 is fitted into the first convex portion 20 and the second convex portion 21 of the same square plate connecting member 10, thereby connecting multiple plate materials b5, b6 in the front-rear direction. In addition, the first convex portion 20b and the second convex portion 21b of another square plate connecting member 10b are fitted into the female stud cf6 of one plate b6, and the first groove portion 12a and the second groove portion 15a of another square plate connecting member 10a are fitted into the male stud cm5 of the other plate b5. In this way, among the multiple plate materials to be connected, the male stud and female stud of the plate materials located before and after it are fitted into the square plate connecting member 10 of the connecting portion located in the middle, and either the male stud or the female stud is fitted at the end. It is possible to connect even more plate materials by repeating the above connections. In this figure, an embodiment using the corner plate connection member 10 is described, but it is self-evident that the plate connection member sets 1 and 2, which include the reinforcing plate connection member 30, can also connect plate materials b5 and b6 located in front and behind by using the third groove portion 32, the fourth groove portion 33, the third convex portion 35, and the fourth convex portion 36 in the same manner.

[0056] As described above, according to the present embodiment of the connecting member 10 for square plates and the method of assembling plates using the connecting member 10 for square plates, the first main groove 13 and the second main groove 16 are provided up to the intersection 23 where the first groove 12 and the second groove 15 intersect, and the first sub-groove 14 and the second sub-groove 17 are provided from the intersection 23 through the side surface of the square body 11. Therefore, of the two plates b1 and b2, at least the first plate b1 can be fitted into the entire first groove 12 or the entire second groove 15. This allows the two plates to be assembled into either an L-shape or a T-shape using only the connecting member 10 for square plates.

[0057] In addition, the opening of the grooves 13, 15 is wide and narrow at the back, and the base of the ridges 20, 21 is thick and narrow at the tip. Furthermore, the narrowed protrusions 18, 34 and the widened protrusions 22, 37 are wedge-shaped and arranged so that the tips of the wedge shapes face each other. Therefore, the plate b can be easily fitted into the grooves 13, 15 and the ridges 20, 21, and the narrowed protrusions 18, 34 and the widened protrusions 22, 37 are securely inserted into the male and female ribs cm and cf. As a result, the corner plate connection member 10 and the plate b are firmly connected after the plate b is fitted, and can be sufficiently supported against external forces applied in the longitudinal direction of the grooves or ridges, which are generally prone to slippage (the same applies to the plate connection member sets 1, 2).

[0058] Furthermore, according to the plate connecting member sets 1 and 2 which include the reinforcing plate connecting member 30 and the plate assembling method using the plate connecting member sets 1 and 2, not only does the reinforcing plate connecting member 30 increase the strength of the plate b during assembly, but by combining the corner plate connecting member 10 with the reinforcing plate connecting member 30, a variety of assembly methods can be selected, such as L-shape, T-shape and cross shape, using two to four plate materials b.

[0059] In the plate assembly method, the wide surface ws of one plate can be abutted against the side surface cs of the cut edge of another plate, or the side surfaces cs of the cut edges of plates that are butted together can be abutted against each other. This increases the rigidity of the connection points between the corner plate connecting member and the reinforcing plate connecting member plate, and allows the assembled shelf, table, etc. to have sufficient strength even without providing braces, back panels, etc.

[0060] The above-mentioned corner plate connecting member 10, plate connecting member sets 1 and 2, and plate assembling method are examples of the present invention, and their configurations can be appropriately changed without departing from the spirit of the invention. For example, as shown in Figures 15(A) and (B), a plate connecting member set 101 in which the corner plate connecting member 110 is rectangular when viewed from the front and the reinforcing plate connecting member 130 is approximately L-shaped when viewed from the front, or other shapes are possible.
