Frame assembly for vehicle opening and associated method of manufacture
A frame for a vehicle opening and associated method of manufacturing. The frame can include straight segments interconnected by corner segments. The method includes forming the straight segments, heating at least end portions the straight segments, and bonding the corner segments between adjacent straight segments.
1 . A method for manufacturing a frame for a vehicle opening having straight segments interconnected by corner segments, the method comprising:
forming the straight segments;
heating at least end portions of the straight segments;
bonding the corner segments between adjacent straight segments;
wherein bonding the corner segments between adjacent segments occurs after forming straight segments.
2 . The method of claim 1 , wherein bonding the corner segments between adjacent straight segments comprises introducing bonding material.
3 . The method of claim 1 , wherein introducing bonding material includes surrounding the frame with bonding material.
4 . The method of claim 1 , wherein heating comprises heating in an inert gas atmosphere.
5 . The method of claim 1 , wherein bonding comprises injection molding or injection welding.
6 . The method of claim 1 , further comprising selecting the straight segments from a plurality of straight segments having differing lengths to create a frame having a desired dimension.
7 . The method of claim 1 , wherein bonding the corner segments comprises bonding sequentially each corner segment between adjacent straight segments.
8 . The method of claim 1 , wherein bonding the corner segments comprises:
bonding at least a first corner segment;
rotating the frame; and
bonding at least a second corner segment.
9 . The method of claim 8 , wherein at least a first corner segment comprises two consecutive corner segments, and at least a second corner segment comprises at least two other consecutive corner segments.
10 . The method of claim 8 , wherein rotating the frame comprises rotating a table on which the frame is supported.
11 . The method of claim 1 , wherein the frame is a wall frame for the vehicle opening.
12 . The method of claim 1 , wherein the frame is a panel frame of a movable closure member for the vehicle opening.
13 . A frame assembly for a vehicle opening comprising:
a frame having a plurality of straight segments interconnected with corner segments, wherein:
the straight segments are selected from a plurality of straight segments having various lengths prefabricated; and
the corner segments are bonded between pairs of adjacent straight segments.
14 . The frame assembly of claim 16 , wherein the frame is a wall frame for the vehicle opening.
15 . The frame assembly of claim 15 , wherein the straight segments are extruded.
16 . The frame assembly of claim 15 , wherein the straight segments are cut to a desired size after extrusion.
17 . The frame assembly of claim 13 , wherein the corner segments are injection molded or injection molded.
18 . The frame assembly of claim 13 , wherein the frame comprises thermoplastic material.
19 . A method for manufacturing a three-dimensional structure having at least a first segment connected to a second segment, the method comprising:
forming the first segment;
heating at least an end portion of the first segment;
bonding the second segment to the first segment; and
wherein forming the first segment occurs after bonding the second segment to the first segment.
20 . The method of claim 19 , wherein bonding comprises injection molding or injection welding.
