1. a fabric sign board comprises that at least one pair of is installed to a parallel support spare (1,2) and a fabric (3) on the base plate (6), and fabric comprises two parallel border areas (4,5) that are assemblied on each supporting member, and at least one supporting member (1) comprises-one frame section (7) comprises-one installing zone (14) that is installed to base plate (6), and-one rear support district (12) comprises-one inner wall section (17) forms the extendible portion of above-mentioned installing zone (14),-one flange shape external wall section (19) has a free end bearing end (20), forms a rotating fulcrum (A), and-one end-wall section (18) that connects inside and outside wall section (17,19), above-mentioned wall section (17,18,19) have determined that between them clamps a chamber (25);

  • And-one clamps section bar (8), and fabric (3) is clamped on the frame section (7), clamps section bar (8) and comprises-one manual pressure district (28),-clamping device (48,49) is used for the border area (4) of clamping fabric, and-one bonding land (27), when pressor areas (28) is forced into installing zone (14) and clamps section bar (8) when above-mentioned fulcrum (A) rotates, this bonding land is arranged to cooperate with the inside and outside wall section (17,19) of rear support district (12), produces tensile stress simultaneously in fabric (3);

    Be characterised in that;

    in the cross section of frame section (7), see, the external wall section (19) in rear support district (12) has predetermined minimum extension, this minimum extension allows that clamping section bar (8) surpasses by frame section and clamping section bar (7,8) equilibrium state that a predetermined angle between is determined, when the over balance state, the effect of tensile stress moves to a latched position clamping section bar (8), clamp section bar (8) and engage with frame section (7) locking in this latched position, above-mentioned latched position is kept by tensile stress.
