Abstract
A clip for assembling corners of hollow members such as the rails and stiles of an extruded aluminum door. The clip has an L shape and may feature a double L shape. A portion inserts into the hollow of a first member and is attached thereto. Another portion extends into the other hollow member for attachment thereto to form a sturdy joint without welding. Pairs of clips may be used at each corner.
Claims27
A structure, comprising:
- a first member having an interior hollow and a slot in a side thereof extending through the first member into the interior hollow;
- a second member having an interior hollow and an open end, the open end communicating with the interior hollow thereof;
- a clip for attaching the first member to the second member, the clip having a first leg, a second leg and a third leg, the first leg having a lower portion and an upper portion, the lower portion and the upper portion being substantially parallel and laterally spaced by an offset extending there between, the first leg and second leg being attached at a first angle distal to the offset and the third leg being attached to the first leg and extending in a direction with a component parallel to a direction of extension of the second leg, the third leg being longitudinally spaced from the second leg, the upper portion of the first leg capable of being inserted into the slot in the first member and the clip capable of being rotated into a position with the clip contacting the first member within the interior hollow, the clip capable of contacting the first member exterior to the hollow and being fastened to the first member, the second leg and the third leg capable of inserting into the open end of the second member and being fastened to the second member.
A structure, comprising:
- a first member having an interior hollow and a slot in a side thereof communicating with the interior hollow;
- a second member having an interior hollow and an open end, the open end communicating with the interior hollow thereof;
- a clip for attaching the first member to the second member, the clip having a first leg, a second leg, a third leg and a fourth leg, the first leg and second leg being conjoined at a first angle forming a first conjunction and the third leg being attached to the first leg at an end thereof distal to the second leg forming a second conjunction, the third leg extending along the first leg proximate and substantially parallel to a surface thereof distal to the second leg and in a direction toward the first conjunction, the fourth leg extending from a third conjunction with the third leg distal to the second conjunction, the fourth leg extending parallel to the second leg along a portion of the length of the second leg proximate the first conjunction, the first leg and the third leg capable of being inserted into the slot in the first member and the clip capable of being rotated into a position with the first leg contacting the first member within the interior hollow, and being fastened to the first member, the second leg capable of inserting into the open end of the second member and being fastened to the second member.
