 The present invention will be described below with reference to the embodiments shown in the drawings. As shown in a perspective view of an embodiment of the present invention in FIG. 1, the pillar locking device 1 is attached to an upper end position of a lower pillar 3 into which an upper pillar 2 is fitted. 3, a fixing band 4 fitted to the upper end of the fixing band 3, a locking body 6 fixed to a mounting portion 5 projecting to one side of the fixing band 4, and a rotation and axial direction of the locking body 6. A locking shaft 7 (shown in FIG. 5) which is slidably inserted and whose shaft end 7a is fitted and locked in one of the locking holes 8 vertically arranged on the side surface of the upper columnar body 2. An operation knob 9 fixed to the outer end of the locking shaft 7 and a spring 10 for urging the locking shaft 7 in the direction of pulling the locking shaft 7 toward the column.

The fixing band 4 is formed by winding a metal plate material in a loop shape, and mounting portions 5 and 5 extending parallel to each other from respective ends thereof, and the loop portion 4 a has an upper end of the lower columnar body 3. The upper end of the loop portion 4a is bent inward so that the bent portion 4b is hooked on the upper end surface of the lower column 3 as shown in FIG. ing.

The locking body 6 is made of plastic, and has a cylindrical body body 6 a, and a plate that is protruded from the upper surface of the body body 6 a and is sandwiched between the mounting portions 5 and 5 of the fixing band 4. And a groove 6c, 6c into which the bent portion 5a, 5a formed at the upper end of the mounting portion 5, 5 of the fixing band 4 is fitted, is formed on the outer surface of the upper end of the mounting portion 6b. After they are fitted together, they are fastened with bolts 11 and nuts 12.

One end surface of the body body 6a is formed into an arcuate concave curved surface 6d so as to be in close contact with the outer peripheral surface of the lower columnar body 3. Inside the body body 6a, a spring chamber 6e whose bottom surface is open is formed. The locking shaft 7 fixed to the operating knob 9 is slidably passed through the spring chamber 6e from the other end surface side of the body body 6a to the concave curved surface 6d side.

A flange 7b is provided at a portion of the locking shaft 7 located inside the spring chamber 6e, and a spring 10 is provided between the flange 7b and the inner surface of the spring chamber 6e on the operation knob 9 side. By virtue of the elasticity of the spring 10, the tip 7a of the locking shaft 7 has a habit of always protruding from the concave curved surface 6d through a hole (not shown) of the lower columnar body 3.

A U-shaped engaging groove 9a is formed on the side of the body 6a of the operating knob 9, and the body main body 6a is fitted into the engaging groove 9a as closely as possible. When the engaging groove 9a of the operating knob 9 and the protruding portion 6f of the body 6a are fitted with each other, the protruding portion 6f having a matching width is formed, and the tip 7a of the locking shaft 7 is located inside the lower columnar body 3. When the operation knob 9 is turned to about 90 ° and its end surface rides on the convex portion 6f of the body 6a, the tip end 7a of the locking shaft 7 is kept retracted from the concave curved surface 6d. Has been done.

Locking holes 8, 8 ... In which the tip 7a of the locking shaft 7 can be fitted, are arranged in the upper column 2 in the axial direction at predetermined intervals.

Therefore, when the engaging groove 9a of the operating knob 9 and the convex portion 6f of the body 6a are fitted, the locking shaft 7 integral with the operating knob 9 is biased by the spring 10. 7a of the upper column 2 protrudes through the lower column 3 and is fitted into one of the locking holes 8 of the upper column 2 so that the upper column 2 is locked to the lower column 3 at that position. It is fixed keeping its height.

In order to adjust the height of the upper columnar body 2, the operating knob 9 is pulled against the spring 10 and turned by about 90 ° so that the end surface of the operating knob 9 is placed on the convex portion 6f of the body 6a. When it is located, the operating knob 9 is held in that position without being pulled in, and at the same time, the tip 7a of the locking shaft 7 is left in a state where it is pulled out from the locking hole 8 of the upper column 2 and the upper column 2 Is released from the bond and can move up and down.

Next, the upper column 2 is adjusted to a desired height position, and when the operating knob 9 is turned again by approximately 90 °, the engaging groove 9a fits into the convex portion 6f of the body 6a, and the spring 10 A forward force is applied to the locking shaft 7 by the urging force. When the upper pillar 2 is raised and lowered in this way, the tip 7a of the locking shaft 7 is fitted into the locking hole 8 located in the vicinity of the upper pillar 2 by the biasing force of the spring 10, whereby the upper pillar 2 is lowered. It is fixed at that height position.

FIG. 7 shows a modified example of the present invention, in which the tip 7 a of the locking shaft 7 is cut obliquely, and the projecting end portion 7 c has a length capable of entering the locking hole 8 of the upper column 2. The base end portion 7d is located at a position separated from the locking hole 8 at that time.

Therefore, as shown in FIG. 7, when the protruding end portion 7c is located on the upper side, the protruding end portion 7c engages with the upper end of the locking hole 8 of the upper columnar body 2 to prevent the lowering of the upper columnar body 2. When pulling the upper column 2 upward, the lower end of the locking hole 8 pushes the locking shaft 7 against the spring 10, so that the height of the upper column 2 does not need to be pulled by hand. The height can be adjusted.

Further, the operating knob 9 is pulled to remove the engaging groove 9a from the convex portion 6f of the body 6, and the knob 9 is rotated 180 ° to fit the engaging groove 9a and the convex portion 6f again. By doing so, the protruding end portion 7c of the locking shaft 7 comes to engage with the lower end of the locking hole 8, and the upper column body 2 is prevented from coming off with respect to the lower column body 3. Therefore, at the time of transportation or the like, the state in which the upper pillar 2 is stored in the lower pillar 3 can be maintained by performing the above.

FIG. 8 shows a case of a hanger rack as an application example of the present invention, in which lower pillars 3 and 3 which are erected on the left and right bases 13 and 13 and which are fitted therein. The upper pillars 2 and 2 are provided, and the horizontal casket 14 is fixed between the upper ends of the upper pillars 2 and 2, and the hanger 15 is hung on the upper, so that the height of the pillars can be adjusted. For this purpose, the locks 1, 1 according to the present invention are used.
