ABSTRACT:
A leg block joining system for table is disclosed. An assembly 1 is made of a synthetic resin, and includes opposite side wall plates 3 and 3', a projected edge 2, and supporting guiding portions 4, 4', 5, 5', 6, 6', 7 and 7'. The assembly 1 further includes bolt passages 8, 8', 10 and 10' and tool passages 9, 9', 11 and 11' having small diameters, the two sets of passages being formed in a shape of cross. A leg 14 having a rectangular cross section is provided with tool holes 15, 16 and 16', and bolt holes 17, 17', 18 and 18'. The assembly 1 is inserted into the leg 14, in such a manner that the tool passages and the bolt passages of the assembly 1 should be aligned with the tool holes and the bolt holes of the leg 14. Then connecting beams 19, 19' and 19" are connected to four of the legs 14, and then, upper and lower bolts are tightened into bolt tightening holes 20, 20', 20", 21, 21' and 21", thereby firmly joining the legs 14 and the connecting beams. Then an upper plate of the table is mounted and tightened through tightening holes 22, 22", 23 and 23' thereby completing the assembling of a table.
