Thereafter, when the adjustment rods 12, 12 lift the hanger rod 33, the locking claw 17 swings about the pin 16 via the spring 31 because the upper edge 10a of the locking convex portion 10 is provided obliquely. It can be moved upward repeatedly, and when the lifting force is released at a predetermined height position, it is locked by the locking protrusion 10 near that position. In this case, since the lower edge 10b side of the locking recess 10 is formed in an open-cut shape as shown in the figure, the hook-shaped lower jaw 19 is locked to the same edge 10b and is prevented from moving downward, and the hanger rod 33 is held in a predetermined position. It is held at a height of . In addition, when adjusting the hanger rod 33 to a height lower than a certain height, push down the knob member 32, retract the hook-shaped lower jaw 19 of the locking claw 17 into the slider 14, and then push it down to the desired height. By releasing the push-down force at the position, the locking pawl 17 engages with the locking protrusion 10 at that height position in the same way as described above, and the hanger rod 33 can be locked and held at the same position. Furthermore, by engaging the locking pawl 7 with the upper fixing hole 8, the adjustment rod 12 is prevented from lowering and coming off from the fixing column 3, and the hanger rod 33 can be locked and held at the highest height. . In particular, when assembling the hanger 1, if the positioning tool 6 is installed inside the fixed column 3, it is rotatably attached to the support leg 4 of the base 2 via the bolt 11, so for example Even if an error occurs in the mounting direction of the slider 14 attached to the lower end of the moving pipe 13, or even if the left and right sliders 14 are attached in different directions when attaching the hanger rod 33, the slider 14 can be easily fitted. Moreover, even if the slider 14 is assembled in this state, the vertical movement function and locking and holding function of the slider 14 described above are not lost, so that the assembly work efficiency can be improved.

In the above embodiment, a pair of fixed columns 3 are erected on the base 2, and the left and right adjusting rods 12 are provided in a substantially gate shape via hanger rods 33, so that the fixed columns 3 can be moved up and down. However, the present invention is not limited to this. For example, as shown in FIG. 10, one fixed column 3 is erected on a cross-shaped base 2A, and a hanger rod is attached to the upper end of this fixed column 3. 34 may be a hanger 1A in which an adjusting rod 12 extending horizontally from side to side is inserted so as to be movable up and down. In addition, as shown in FIG. 11, fixed columns 3 are erected at the four corners of the base 2B, which is framed in a substantially rectangular shape, and an adjustable rod 12 formed in a substantially gate shape is inserted between the corresponding fixed columns with hanger rods 33. It is also possible to use a hanger 1B in which the adjusting rod 12 is inserted so as to be movable up and down, and the adjusting rod 12 is further connected by a connecting rod 35.

(Effects of the invention) The present invention has a hanger support structure consisting of a fixed support that stands on a base, and an adjustment rod that is inserted into the fixed support so that it can move up and down, and has a hanger rod attached to its upper end. A slider having a locking pawl is fixed to the lower end of the inner diameter of the adjustment rod, and the locking pawl engages with the lower end of the operating rod that is elastically attached to the upper end of the adjustment rod via a compression spring. The hook-shaped lower jaw of the locking pawl is connected to the slider so as to be retractable from the slider, and the fixed support has upper and lower fixing holes, and a plurality of locking recesses are provided between the fixing holes, so that the slider can be attached to the slider. The lower end of the positioning tool, which has a substantially C-shaped cross section and slides and guides the hanger rod to lock and hold the hanger rod at a predetermined height position via the locking pawl, is rotatably erected with respect to the base. By having this configuration, when the adjustment rod is pushed down, the locking claw of the slider that connects and engages with the adjustment rod is recessed into the slider, and the positioning tool is installed to slide and guide the slider installed in the fixed column. It is possible to disengage the upper and lower fixing holes and the plurality of locking recesses provided between the fixing holes, and adjust the vertical movement. The lower edge of the locking recess and the hook-shaped lower jaw of the locking claw are locked, so that the hanger rod can be locked and held at a predetermined height. Also,
It has a double structure in which the sliding tube of the adjustment rod is fitted inside the fixed column, and a positioning tool is installed inside it, so
The outer diameter difference between the fixed column and the sliding tube is reduced, improving the appearance, and the positioning tool inside the fixed column is rotatably attached to the support leg of the base via a bolt. For example, if there is an error in the mounting direction of the slider attached to the lower end of the sliding tube, or if the left and right sliders are installed in different directions when installing a hanger rod, the slider will not fit. This can be easily done, and even if the slider is assembled in this state, the vertical movement function and locking and holding function of the slider described above will not be lost, so that the assembly work efficiency can be improved.
