Abstract

A system for improving alignment in welded assemblies is provided. The system includes a support member having a surface and a projection extending from the surface. The projection may include one of a convex or a concave geometry. The system includes a positioning member provided over the support member for receiving a frame member. The positioning member may be movable over the support member, and the positioning member may include a geometry configured to engage the one of the convex or the concave geometry. The frame member may be movable from a first position relative to a center of the projection to a second position relative to the center of the projection during movement of the positioning member over the support member.

First claim

What is claimed is:

1. A system, comprising:
a support member including a surface and a projection extending from the surface, the projection having one of a convex geometry or a concave geometry; and
a positioning member positioned over the support member,
wherein the positioning member includes a seat or ledge configured for a frame member to be disposed over the seat or ledge,
wherein the positioning member is movable over the support member by way of one or more of swiveling, gliding, sliding, rotating, tilting, or pivoting,
wherein the positioning member has a geometry configured to engage the one of the convex geometry or the concave geometry,
wherein the frame member is directly welded, brazed, swaged, or crimped to the positioning member, and
wherein the frame member is movable from a first position relative to a center of the projection to a second position relative to the center of the projection during movement of the positioning member over the support member.

2. The system of claim 1 ,
wherein the projection has the convex geometry, and
wherein the convex geometry is at least partially nested within the positioning member.

3. The system of claim 1 , wherein an inner wall of the frame member is disposed around an outer wall of the positioning member.

4. The system of claim 1 , wherein the frame member comprises a tube.

5. The system of claim 1 ,
wherein the support member comprises a plurality of projections extending from the surface, and
wherein the plurality of projections include the projection.

6. The system of claim 5 , further comprising:
a plurality of positioning members disposed over the plurality of projections; and
a plurality of frame members attached to the plurality of positioning members,
wherein a first positioning member, of the plurality of positioning members, is configured to position a first frame member, of the plurality of frame members, at a first angle relative to the surface of the support member,
wherein the positioning member is the first positioning member,
wherein the frame member is the first frame member,
wherein a second positioning member, of the plurality of positioning members, is configured to position a second frame member, of the plurality of frame members, at a second angle relative to the surface of the support member, and
wherein the first angle is different than the second angle.

7. The system of claim 1 , wherein an inner wall of the frame member is disposed around an outer wall of the positioning member.

8. A system, comprising:
a support member including a surface and a projection extending from the surface, the projection having one of a convex geometry or a concave geometry;
a positioning member positioned over the support member,
wherein the positioning member is movable over the support member by way of one or more of swiveling, gliding, sliding, rotating, tilting, or pivoting, and
wherein the positioning member has a geometry configured to engage the one of the convex geometry or the concave geometry; and

a frame member attached to the positioning member,
wherein the positioning member includes a seat or ledge configured for the frame member to be disposed over the seat or ledge,
wherein the frame member extends along an elongate axis,
wherein the frame member is movable from a first position relative to the surface of the support member to a second position relative to the surface of the support member during movement of the positioning member over the support member,
wherein, when the frame member is in the first position, the elongate axis is disposed at a first angle relative to the surface,
wherein the frame member is directly welded, brazed, swaged, or crimped to the positioning member, and
wherein, when the frame member is in the second position, the frame member is disposed at a second angle relative to the surface, the second angle being different than the first angle.

9. The system of claim 8 ,
wherein the projection has the convex geometry, and
wherein the convex geometry is at least partially nested within the positioning member.

10. The system of claim 8 , wherein the frame member is disposed around the positioning member.

11. The system of claim 8 , wherein the frame member is spaced apart from the support member by the positioning member.

12. The system of claim 8 , wherein the frame member comprises a tube.

13. The system of claim 8 ,
wherein the support member comprises a plurality of projections extending from the surface,
wherein the plurality of projections include the projection,
wherein the plurality of projections are configured to engage a plurality of positioning members, and
wherein the plurality of positioning members include the positioning member.

14. An assembly comprising:
a support member comprising a first projection and a second projection;
a first positioning member disposed over the first projection,
wherein the first positioning member is movable relative to the first projection by way of one or more of swiveling, gliding, sliding, rotating, tilting, or pivoting;

a second positioning member disposed over the second projection,
wherein the second positioning member is movable relative to the second projection;

a first frame member attached to the first positioning member; and
a second frame member attached to the second positioning member,
wherein the first positioning member includes a seat or ledge configured for the first frame member to be disposed over the seat or ledge,
wherein the first frame member is movable in a first plurality of positions relative to a center of the support member when the first positioning member moves relative to the first projection, and
wherein the second frame member is movable in a second plurality of positions relative to the center of the support member when the second positioning member moves relative to the second projection.

15. The assembly of claim 14 , wherein:
the first projection comprises a first convex geometry;
the first positioning member comprises a first concave geometry configured to engage the first convex geometry;
the second projection comprises a second convex geometry; and
the second positioning member comprises a second concave geometry configured to engage the second convex geometry.

16. The assembly of claim 14 , wherein the first positioning member and the second positioning member are weldable to the support member.

17. The assembly of claim 14 , wherein:
the first frame member is welded to the first positioning member; and
the second frame member is welded to the second positioning member.

18. The assembly of claim 14 , wherein the first projection is adjacent to the second projection.

19. The assembly of claim 14 , wherein the first projection and the second projection are coaxial.

20. The assembly of claim 14 , wherein an inner wall of the first frame member is disposed around an outer wall of the first positioning member.
