Since the first engaging portion 43 and the second engaging portion 66 are provided at the corners, respectively, and the first support member 31 and the second support member 32 are engaged at the corners, it is difficult to shift and rattle. It is possible to provide an assembly strut with excellent stability. In addition, since a plurality of the first engaging portions 43 and the second engaging portions 66 are provided at predetermined intervals in the longitudinal direction, the engaging portions of the first engaging portions 43 and the second engaging portions 66 can be changed. Thus, it is possible to provide the assembly strut 1 whose strut length can be changed. Since the length of the strut can be easily changed without using a tool or the like, it is easy to handle and highly convenient.

The first engaging portion 43 has a first extending portion 54 extending from the inner corner surface 42 and a second extending portion 55 extending from the first extending portion 54 in a direction different from that of the first extending portion 54. The second engaging portion 66 has a third extending portion 75 extending from the corner outer surface 65 and a fourth extending portion 76 extending from the third extending portion 75 in a direction different from that of the third extending portion 75. The engaging portion 43 and the second engaging portion 66 have shapes that substantially fit each other.

Further projections 58 and grooves 79 are provided on the second extension 55 and the fourth extension 76, thereby providing the assembly strut 1 that is less likely to shift, is less likely to rattle, and has excellent stability. be able to.

In addition, the assembly strut 1 includes at least one restricting portion 59 provided on one of the corner inner surface 42 of the first strut member 31 and the corner outer surface 65 of the second strut member 32, and the corner of the first strut member 31. A plurality of restriction receiving portions 81 are provided on the other of the inner surface 42 and the corner outer surface 65 of the second strut member 32 to receive the restriction portion 59 . By providing the restricting portion 59 and the restriction receiving portion 81, the engagement range between the first engaging portion 43 of the first strut member 31 and the second engaging portion 66 of the second strut member 32 is restricted and assembled. The strength and stability of the strut can be increased.

If the strut is lengthened, the overlapping portion between the first strut member 31 and the second strut member 32 will be shortened. Therefore, by providing the restricting portion 59 and the restricting receiving portion 81, the overlapping portion of the first strut member 31 and the second strut member 32 of a predetermined amount or more is ensured. For example, the restricting portion 59 is a convex portion arranged on the base end side of one of the first strut member 31 and the second strut member, and the restriction receiving portion 81 is located between the first strut member 31 and the second strut member 32 . and a concave portion arranged from the other base end side to the central portion. Since there is no restriction receiving portion on the tip side, when the first strut member 31 and the second strut member 32 are assembled, the first strut member 31 and the second strut member 32 are overlapped by a predetermined amount or more. Further, when the restricting portion 59 and the restricting receiving portion 81 are engaged with each other, the plurality of first engaging portions 43 and second engaging portions 66 are engaged with each other. can be enhanced.

In addition, the assembly column 1, the first mounting portion 11 connected to the distal end of the assembly column 1, and the second mounting portion 12 connected to the proximal end of the assembly column 1 are provided. can store and display articles and products of various heights by changing the length of the support and changing the spacing between the upper and lower mounting parts of the support, which is highly convenient . Unlike assembly struts, which connect multiple relatively short strut members to lengthen the strut, the length of the strut can be changed without changing the number of strut members. There is no problem that too many members need to be stored. Since the number of members constituting the support is small and the plurality of engaging portions are provided at the corner portions, it is possible to provide an assembly that is less likely to be displaced and less likely to rattle.
