The invention relates to a pivot means for a desk top. Said means of the invention comprises two arm members whose first ends are articulated to the desk body and which are both fitted with a flange bearing against the desk body for supporting the arm members inclined towards the front edge of the top. The top is articulated to the opposite ends of said arm members by means of said arm members connecting pin in such a manner that the top rear edge can be erected on the vertically supported arm members and lowered down by moving the top onto the arm members pivoted towards the rear edge of the desk body. The bottom face of the top near the front edge of the top can be provided with a locking groove corresponding to a shoulder-shaped retainer formed in the desk body for locking the top on the desk body in the front-edge direction. |
