Abstract

A rod hanger uses a spring insert clip horizontally insertable into a sheet metal housing to embrace and grip the threads of a vertical rod. The hanger has a sheet metal housing with parallel slots in opposite walls parallel to the rod. The clip has spring thread-form legs which are guided into the slots and held embracing the rod. The clip is U-shape with parallel legs which project from and snap behind one of the walls of the housing. The hanger may be in the form of a beam clamp or flange clip.

Claims

1. A rod hanger comprising:

a body adapted to be secured to a building structure, wherein the body includes a threaded rod receiving portion accommodating a vertically extending threaded rod therethrough generally clear of the building structure, and

an insert clip in said rod receiving portion gripping the threaded rod to secure it in vertical position,

wherein said rod receiving portion includes a sheet metal housing with slots in opposite side walls generally parallel to the rod to receive the insert clip,

wherein said insert clip has a U-shape and has parallel spring legs each having a linear series of grooves forming a thread form profile in each leg,

wherein the thread form profiles in the respective legs are offset from each other by one half the pitch of the threads of the rod,

wherein said housing has angled projections to guide tips of the legs of the insert clip from one set of the slots to another set of the slots, and

wherein said sheet metal housing includes aligned notches to receive a beam flange, and a clamp screw to clamp the hanger to said beam flange.

2. A hanger as set forth in claim 1 wherein the sheet metal housing includes a rear wall that is attached to both of the side walls.

3. A rod hanger comprising:

a body adapted to be secured to a building structure, wherein the body includes a threaded rod receiving portion accommodating a vertically extending threaded rod therethrough generally clear of the building structure, and

an insert clip in said rod receiving portion gripping the threaded rod to secure it in vertical position,

wherein said rod receiving portion includes a sheet metal housing with slots in opposite side walls generally parallel to the rod to receive the insert clip,

wherein said insert clip has a U-shape and has parallel spring legs each having a linear series of grooves forming a thread form profile in each leg,

wherein the thread form profiles in the respective legs are offset from each other by one half the pitch of the threads of the rod,

wherein said housing has angled projections to guide tips of the legs of the insert clip from one set of the slots to another set of the slots, and

wherein said sheet metal housing includes an extension terminating in an edge clip.

4. A hanger as set forth in claim 3 wherein said edge clip is angled with respect to the extension.

5. A hanger as set forth in claim 3 wherein said edge clip is generally parallel to said extension.

6. A hanger as set forth in claim 3 wherein said edge clip is generally perpendicular to said extension.

7. A threaded rod hanger comprising:

a sheet metal body, wherein the body includes a first portion adapted to be fixed to a building structure, and a rod receiving portion offset from the first portion accommodating a threaded rod vertically therethrough clear of the structure, and

an insert clip in said rod receiving portion operative to grip the threaded rod to hold it in a selected vertical position,

wherein said body includes opposite side walls generally parallel to the threaded rod, and parallel slots in said opposite side walls generally parallel to the rod to receive the insert clip,

wherein said insert clip has a U-shape and has parallel spring legs each having a linear series of grooves forming a thread profile,

wherein the profiles in the respective legs are offset from each other by one half the pitch of the threads of the rod,

wherein said body has angled projections to guide tips of the legs from one set of the slots to another set of the slots, and

wherein said sheet metal body includes aligned notches to receive a beam flange, and a clamp screw to clamp the hanger to said beam flange.

8. A hanger as set forth in claim 7 wherein said angled projections engage and back up said legs to hold the thread forms against the rod.

9. A hanger as set forth in claim 8 wherein the tips of the legs project through the slots of one wall when the insert clip is fully inserted in the slots of the other.

10. A hanger as set forth in claim 9 including projections on the outsides of said spring legs adapted to snap behind the slots in said one wall to lock the insert clip in place.

11. A threaded rod hanger comprising:

a sheet metal body, wherein the body includes a first portion adapted to be fixed to a building structure, and a rod receiving portion offset from the first portion accommodating a threaded rod vertically therethrough clear of the structure, and

an insert clip in said rod receiving portion operative to grip the threaded rod to hold it in a selected vertical position,

wherein said body includes opposite side walls generally parallel to the threaded rod, and parallel slots in said opposite side walls generally parallel to the rod to receive the insert clip,

wherein said insert clip has a U-shape and has parallel spring legs each having a linear series of grooves forming a thread profile,

wherein the profiles in the respective legs are offset from each other by one half the pitch of the threads of the rod,

wherein said body has angled projections to guide tips of the legs from one set of the slots to another set of the slots, and

wherein said body includes an extension terminating in an edge clip.

12. A hanger as set forth in claim 11 wherein said edge clip is angled with respect to the extension.

13. A hanger as set forth in claim 11 wherein said edge clip is generally parallel to said extension.

14. A hanger as set forth in claim 11 wherein said edge clip is generally perpendicular to said extension.

15. A rod hanger comprising:

a body adapted to be secured to a building structure, wherein the body includes a threaded rod receiving portion accommodating a vertically extending threaded rod therethrough generally clear of the building structure; and

an insert clip in said rod receiving portion gripping the threaded rod to secure it in vertical position;

wherein said rod receiving portion includes a sheet metal housing with slots in opposite side walls generally parallel to the rod to receive the insert clip;

wherein said insert clip has a U-shape and has parallel spring legs each having a linear series of grooves forming a thread form profile in each leg;

wherein the thread form profiles in the respective legs are offset from each other by one half the pitch of the threads of the rod;

wherein said housing has angled projections to guide tips of the legs of the insert clip from one set of the slots to another set of the slots;

wherein the sheet metal housing includes a rear wall that is attached to both of the side walls;

wherein one of the angled projections is struck from the rear wall; and

wherein the one of the angled projections extends from the rear wall at an acute angle.

16. A rod hanger as set forth in claim 15 wherein said angled projections engage and back up said legs to hold the thread form profiles against the rod.

17. A rod hanger as set forth in claim 16 wherein the tips of the legs project through the slots of one wall when the insert clip is fully inserted in the slots of the other.

18. A rod hanger as set forth in claim 17 including projections on the outsides of said spring legs adapted to snap behind the slots in said one wall to lock the insert clip in place.

19. A hanger as set forth in claim 15,

wherein another of the angled projections is struck from one of the side walls;

and

wherein the another of the angled projections extends from the one of the side walls.

20. A hanger as set forth in claim 19,

wherein the another of the angled projections includes an angled arm and a tip bent relative to the arm;
