On the other hand, when the caster 11 is lowered by turning the handle 12 in the opposite direction, the caster 11 hits the floor and the base frame 2 floats, so that the movable support 1 can travel on the floor and move freely.

On each base 7, a plurality of column supports 13 are provided in the longitudinal direction.
Are installed at regular intervals, and a plurality of columns 3 are installed at predetermined intervals on the base 7 via the column receivers 13.

The column support 13 is formed in a substantially square cross section, and the column 3
Is formed in a substantially square cylindrical shape that is slightly larger than the column support 13. And each pillar 3 has a pillar support at its lower end.
It is supported vertically by inserting 13.

At a middle part of each support 13, a support fixture 14 for receiving the lower end of the support 3 is attached. Post fixing bracket 14
A fixing nut 15 is welded to a substantially central portion of the vertical portion 14a,
Further, a through hole (not shown) is formed continuously with the screw hole of the fixing nut 15.

A column fixing bolt 16 is screwed into the fixing nut 15, and the tip of the column fixing bolt 16 penetrates through the through hole of the vertical portion 14a and strongly contacts the side surface of the column 3 so that the lower end of the column 3 It is supported so that it does not come off from the column receiver 13.

A horizontal connecting beam 17 is bridged over a lower end, an intermediate portion, and an upper end of the column 3, respectively. The lower end, the intermediate portion, and the upper end of each column 3 are connected by the horizontal connecting member 17, respectively. A plurality of struts 4 and struts 5 are bridged between 3, 3, and are strongly reinforced by the struts 4 and struts 5.

The column 3, the horizontal connecting member 17, and the major difference 5 are connected by a clamp 18 that can simultaneously connect members in three directions, thereby facilitating the assembling work by minimizing connecting metal fittings and connecting portions. (See FIG. 4).

Further, the horizontal connecting member 17 and the struts 14 are connected by a configuration as shown in FIG. 5, and when the configuration is described, a bracket 19 is protruded from the horizontal connecting member 17 and a substantially central portion of the bracket 19 is provided. A connecting shaft 20 protrudes from the connecting shaft 20, and a stopper 21 is attached to the connecting shaft 20. on the other hand,
The tip of the streak 4 is formed flat, and a connection hole is formed in the center.
