Abstract

A built-up screen coupling structure, comprising at least two screen board frames side matched together by a plurality of fastening devices and at least an adjusting device. The screen board frames have each at least a side end having a slot at the top and a plurality of relatively smaller openings at the outer side. The openings are respectively divided by a plurality of dividing boards. The fastening devices are respectively fastened in the openings and clamped on the dividing boards to connect two screen board frames together. The adjusting device is fastened in the slot to secure the connection.

Claims

1. A built-up screen coupling structure, comprising:

at least two screen board frames, each of said screen board frames defining a side end having a slot formed within a top portion thereof and a plurality of relatively smaller openings along on outer side, said smaller openings defining therebetween a plurality of dividing planar portions of substantially equal dimension and spaced at equal intervals;

at least one adjusting device mounted within one of said slots within the top portion of the side end of one of said screen board frames, said adjusting device having an L-shaped base, a top board, a compression spring and a bolt, said L-shaped base defining an inner wall having a first groove, a bolt hole and a second groove respectively formed therein, said top board being transversely fastened in the first groove of said L-shaped base and having a top board groove and a bolt hole respectively formed therein at locations substantially aligned with the second groove and the bolt hole of said L-shaped base, said bolt being respectively fastened in the bolt holes on said top board and said L-shaped base, said compression spring being sleeved on said bolt and retained between said top board and said L-shaped base;

a plurality of fastening devices respectively fastened in said screen board frame smaller openings to secure at least two screen board frames together, said fastening devices substantially defining an inverter U-contour, having an inclined side wall obliquely extending downward from a vertical side wall, defining therein a retaining space for retaining a plate spring, said plate spring having a curved end fastened in a groove formed within said oblique side wall on an external surface and an opposite end retained within said retaining space; and

at least one face panel having a set of notches formed therein and vertically aligned on a back side with a curved strip spring and a fastening element respectively secured therein for fastening in corresponding holes made on said at least two screen board frames.

2. The built-up screen coupling structure of claim 1, wherein at least two screen board frames can be connected together orthogonal each to the other by a connecting frame, said connecting frame having side channels respectively for insertion therein of said two screen board frames and, being covered with a columnar cover at the top, said columnar cover having holes for mounting an adjusting device each to secure the connection.

3. The built-up screen coupling structure of claim 1, wherein said two screen board frames each have a plurality of notches for mounting a plurality of supporting plates for supporting a table, said supporting plates having a plurality of unitary, hooked strips at one end respectively hooked in the notches on said two screen board frames, and a locking bar locked in either of the notches on said two screen board frames to fixedly secure said screen board frames each to the other.
