<Pedestal assembly>

1 is an exploded perspective view of a chair support assembly according to the present invention.

1, the chair base assembly according to the present invention includes a second panel 120, a hollow fixture 130 fixed to the second panel 120, a seating portion 130 coupled to the fixture 130, And a pedestal 150 installed in any one of the frame 140 and the frame 140 disposed on both sides of the frame 140 (see FIG. Here, the pedestal assembly is an assembly for mounting to a general chair without a pedestal, and can be replaced by a chair provided with a pedestal.

The second panel 120 is plate-shaped and has one or two fasteners 130 mounted thereon and fastened to the lower surface of a chair 101 (see FIG. 2) And has a hole 121. The second panel 120 may be omitted, in which case the fastener 130 is directly fastened to the lower surface of the seat 101 (see FIG. 2).

The second panel 120 further includes an auxiliary opening 122 which is protruded and fixed to one end portion of the second panel 120. The auxiliary opening 122 is provided with a hook member (not shown) for hanging a hair dryer (not shown) Is fixed. The auxiliary aperture 122 may be omitted from the second panel 120.

The fixture 130 has a hollow opening on one or both sides through which the lower portion 141 of the frame 140 is inserted and fastened through an open end face. The fixture 130 has a shape similar to the outer diameter of the frame 140 so that one side of the frame 140 is fitted.

The fastener 130 is fixed to the lower or the side of the seat 101 in the direction transverse to the two armrests 103 (see Fig. 2), and the fastening 130 is fastened to the second panel 120 And the second panel 120 is formed to have a length that is longer than or shorter than both sides of the second panel 120. Here, the fixture 130 may be directly fixed to the lower or the side of the leg 101 without the second panel 120 being removed.

The fixture 130 includes an extension portion 131 extending outwardly from both ends of the incised portion and disposed opposite to each other and a coupling hole 132 formed at least one for coupling the extension portions 131 . Accordingly, the open portion of the fixing member 130 is tightened by bolting through the fitting hole 132 in a state where one side portion of the frame 140 is fitted to the fixing member 130. At this time, the frame 140 is tightened to such an extent that the frame 140 can slide Thereby allowing the frame 140 to move away from or close to the armrest. Of course, the frame 140 may be tightened and fastened to secure it.
