Support bracket assembly for the headrail of window blinds

A support bracket assembly for the headrail of window blinds, comprising a support bracket and a clamping body wherein the support bracket is made up of a horizontal abutment surface and a vertical abutment surface;

• the present invention being characterized by that,
• the support bracket being equipped with a support seat that, extending downwards at one side of the horizontal abutment surface thereof, has a clearance groove defining therein, and a set of vertical fixing holes symmetrically extending through the clearance groove therein;
• both lateral bottom edges of the support seat are respectively disposed a retaining board and multiple support plates, and at one side of the support seat corresponding to that of the vertical abutment surface thereof is preset an accommodation space positioned higher than the retaining board thereof;
• the vertical abutment surface being provided with a slant-cut facet obliquely cut at the bottom edge thereon, and an assembly hole extending upwards in the middle section of the slant-cut facet;
• a set of guide recesses each having a stop end cut at one edge is provided symmetrically defining both sidewalls of the assembly hole thereby;
• the vertical abutment surface also including a set of clearance cavities each having a transverse fixing hole symmetrically indented at both sides of the inner wall thereon;
• the clamping body being made up of a clamping board protruding horizontally at the bottom edge thereon, and multiple oblique guide blocks extending vertically upwards at the other side thereof;
• a limiting slot is disposed extending through the center of the middle guide block thereon, and a pair of pivoting guide plates each having a horizontal stop plane defining thereon is disposed extending symmetrically upwards at both sides of the limiting slot on top of the middle guide block thereof;
• therefore, the guide recesses of support bracket is matched to the pivoting guide plates of the clamping body and a locking element is registered with the limiting slot of the clamping body;
• and via the design of the slant-cut facet cooperatively matched with the oblique guide blocks thereof, the support bracket assembly can be appropriately adjusted upwards/downwards and forwards/backwards to fit to headrails of different sizes for stable location of the headrails thereby, flexibly expanding the range of application and boosting the versatility thereof.
