[Work]

 In the joint according to claim 1 or 2, the side plates of two adjacent free ends of the two strut divisions to be connected respectively come into close contact with the two belly plates of the joint, and the strut divisions Since both side edges are sandwiched by the folded portions of the joint, even if a bending force acts on two adjacent strut divisions, this can be resisted. As a result, it is possible to obtain a strong support column, which in turn makes it possible to obtain an assembly shelf with high strength.

In the joint according to the third aspect, since the joint is provided with the notch, the support pillar divided body and the joint are formed even though there is a shelf supporting protrusion on the inner surface side of the support pillar divided body. Mutual fitting or mutual entry is possible.

In the joint of claim 4, the deep end of the notch in claim 3, that is, the end of the joint farther from the free end side, contacts the support protrusion. This prevents entry of the strut segment into the joint there. Therefore, the joint does not move up and down with respect to the stanchions after the connection of two adjacent stanchions is completed by this joint, and therefore, the stanchions can be prevented from being disassembled when the joint falls.

In the joint according to the fifth aspect, the strut division does not come out of the joint due to the engagement between the engagement protrusion at the intersection of the joint abdominal plates and the engagement hole of the strut division.

At this time, as described in claim 6, when the rear end of the notch provided in the joint and the support projection of the strut dividing body abut as described above, the hole of the strut and the joy If it is configured so as to engage with the engaging projection of the module, the strut dividing body does not move in any of the advancing and retracting directions with respect to the joint.

Further, in this case, as described in claim 7, the engaging projections at the intersecting portions of the joint abdominal plates are constituted by cut-and-raised pieces, and both the cut-and-raised pieces are free. If the ends of the strut are provided so that they face each other, the strut divisions can easily enter the joint (guided by the slope of the cut and raised part), and once the cut and raised part is crossed with the both side plates of the supporting column. When engaging with the provided hole, the free end of the cut-and-raised piece engages with the side edge of the hole, so that the pillar split body is more reliably prevented from coming off. More specifically, when the strut divisions try to escape with respect to the joint, the perimeter of the hole at the intersection of the strut divisions exerts a force on the joint by pressing the free end of the cut and raised portion of the joint. The more the cut-and-raised part rises, the larger the engagement blocking force becomes.

In the joint according to claim 8, a projecting piece extends toward the free end side in the axial direction at the notch inner end of the joint, and the tip of this projecting piece is a supporting projection provided on the strut dividing body. Engages in an axial recess at the base of the. Therefore, this configuration provides an additional anti-bending means in addition to the engagement between the folded-back portion at the joint periphery and the side edge of the strut division.

In the joint of claim 9, the free end of the abdominal plate of the joint extends slightly longer than the folded portion. Therefore, this extension serves as a guide when inserting the strut division into the joint, and the insertion work is easy.

According to the joint of claim 10, in the central portion of the folded-back portion, the side edge of the strut division is engaged more firmly.

【Example】

 10 shows the whole joint of this invention. The joint consists of angle members. That is, the two abdominal plates 12 that are perpendicular to each other are integrally formed, and there is a small-width flat plate portion 14 that is inclined at 45 ° at the connecting portion between the two. Side edges of the shelves 12 and 12 are folded back outward to form a folded portion 16. As will be described later, the folded-back portion 16 holds the side edge of the strut divided body.

The abdominal plates 12, 12 of the joint 10 are provided at their axially free ends with notches 18, 18 extending inward. As will be described later, the position where the notch 18 is provided is a position where the notch 18 engages with the support protrusion of the strut when the two strut divisions have completely entered the joint 10.

The flat plate portion 14 of the joint 10 is provided with engaging protrusions 20 and 20 each having two notches whose free ends face each other. A projecting piece 22 extending to the free end side is provided at the rear end 19 of the notch 18. As will be described later, this projecting piece engages with an axial through hole provided in the support projection of the strut division body.

Further, both free end sides of the abdominal plate 12 of the joint 10 extend longer than the folded-back portion 16 by a. This will serve as a guide when inserting the strut divisions, as described below.

A method of connecting two adjacent strut divisions 40 and 41 by using the joint will be described.

As shown in FIG. 2, one free end side of the joint 10 is brought closer to the free end 42 of the other strut division 40 to be connected. At this time, the two longitudinal edges 44, 44 of the strut segment 40 are aligned with the two folds 16, 16 in the joint, respectively. The strut split body 40 is brought closer to the joint 10, and the free ends 45, 45 of the edge portion 44 of the strut split body 40 are inserted into the free ends 17, 17 of the folded portion 16 of the joint 10 to separate the strut split body. By bringing the end 40 and the joint 10 closer together, the free end 42 of the strut segment 40 substantially enters the joint 10. When the end portion 48 of the support protrusion 46 of the strut division 40 comes into contact with the rear end 19 of the notch 18 of the joint 10 (Fig. 5), the further movement of the support division 40 is stopped. At this time, holes 49 provided at equal intervals at the intersections of the strut divisions 40 are cut and raised to engage with the engaging projections 20 made of pieces. At this time, as shown in FIG. 4, the free end 21 of the engaging projection (cut-and-raised piece) 20 engages with the edge 50 of the hole 49 of the strut division, preventing movement in the opposite direction, that is, slipping out. It When the strut dividing body 40 enters the joint 10, the taper portion of the cut-and-raised piece 20 does not prevent the entry, and when it reaches a predetermined position, the cut-and-raised piece 20 is free. The end side snaps up and engages the hole 49. In this way, the engagement between the support protrusion 46 of the strut dividing body 40 and the rear end 19 of the notch 18 of the joint 10, and the cut-and-raised piece 20 of the joint 10 and the hole 48 of the strut dividing body 40. Due to the engagement, the strut divisions 40 are prevented from further entering and withdrawing from the joint 10.

As described above, when the joint 10 and the strut division body 40 are engaged with each other, the projecting piece 22 provided in the notch 18 of the joint 10 is provided with the shaft on the support protrusion 46 of the strut division body 40. Engage with the through hole 47 in the direction. In this way, relative bending between the joint 10 and the strut divisions 40 is prevented.

After the engagement between the joint 10 and the one strut division body 40 is completed, the other strut division body 41 to be connected should be brought closer to the joint 10 and engaged in the same manner as above. It In this way, the connection of the two pillar division bodies 40 and 41 is completed.

FIG. 6 shows an assembly shelf in which each of the columns 38 is composed of two column divisions 40, 40 connected to each other via the joint 10 and formed by using such columns.

The support protrusion 46 is formed by folding a rectangular portion, which is defined by the upper and lower cutting lines, in the side plate 42 of the support column split body 40 inwardly of the support column split body 40. As a result, as described above, Through holes are formed in the axial direction. The form of the support protrusion 46 is not limited to this.

Further, the form of the engaging protrusion 20 is not limited to that shown in the figure.

Also in the assembly shelf assembled as shown in FIG. 6, the engagement state of the support column 38 and the shelf plate 60 is as shown in FIG.

7 and 8 show another embodiment of the present invention.

In this case, in the joint 10 and the folded-back portion 16, the folded-back piece 52 is compressed more in the axial center portion 55 than both end sides 56, 56, and the distance between the folded-back piece 52 and the base 54 is narrow. Has been formed. Therefore, when the side edge 57 of the strut division 40 is inserted into the folded-back portion 16, the side edge 57 is elastically and firmly clamped at the central portion 55. Therefore, it is preferable that the strut division body 40 be easily inserted into the joint 10 and, moreover, that the strut division body 40 can maintain a strong connected state once it is inserted. In this case, if the side edge 57 of the strut division 40 is formed in a semicircular arc shape as shown in the drawing, a more elastic engagement with the joint 10 can be obtained. In the figure, 53 is an end of the folded piece 52.
