When holding the lifting column 2 in the raised position, use the rib 21 as a guide to hold the lifting column 2 at the abutting stop 24.
1 until it hits the locking plate piece 11, and as shown in FIG.
1 and insert the short leg part 13 of the locking plate piece 11 into the rib break part 23. Then, by pulling down the lifting column 2, the rib 21 is attached to the locking plate piece 1.
1. In addition, when holding the lifting column 2 in the lowered position, pull up the lifting column 2 in the raised position and rotate it in the opposite direction to the above to release the lock between the rib 21 and the locking plate piece 11, as shown in FIG. As shown in FIG.
Pull it down until it hits. Next, as shown in FIG. 3, rotate the lifting column 2 until the rib 21 touches the long leg 12 of the locking plate 11, insert the short leg 13 of the locking plate 11 into the rib break 22, and then remove the lifting column 2. 2 is pulled down by its own weight, thereby locking the rib 21 with the locking plate piece 11 and locking the notch 25 with the lifting column support 14.

る。(Effects of the invention) As detailed above, in the elevating column of the present invention, the elevating column is inserted into the base column so that it can be raised and lowered by positioning the locking plate piece on the inner surface of the upper end of the base column between the ribs on the outer surface of the column. At the raised position of the lifting column, a locking plate piece is inserted into the rib break part, and the rib is locked to the locking plate piece, and at the lowered position of the lifting column, the notch on the lower edge of the lifting column is locked to the lifting column receiver. At the same time, a locking plate piece is inserted into the rib discontinuation part so that the rib is locked to the locking plate piece, so that the lifting and lowering holding mechanism of the lifting column does not protrude outside, and the locking plate piece is inserted inside the base column. formed in
There is no need to worry about tampering with the device, and there is no risk of clothes being caught and torn, or parts of the body being caught and injured. Moreover, no tools or jigs are required for lifting and lowering the lifting column, making the lifting and lowering work easier.
