Abstract

One-piece molded thermoplastic L-shaped and Z-shaped support brackets are described for supporting wiring and/or tubing. The support brackets will include a lower support flange, a backing flange, and a junction region having a concave inner surface and a convex outer surface which integrally joins the lower support flange and the backing flange to one another at a substantially right angle. The support brackets may be provided with a unitarily molded nut plate boss and a metal threaded nut cylinder which is embedded within and overmolded with the nut plate boss. Alternatively, a wire, cable or tubing mount unitarily formed as a one-piece molded unit with one of the support flanges so as to dependently extend therefrom.

First claim

What is claimed is:

1. A one-piece molded thermoplastic support bracket for supporting wiring and/or tubing, the support bracket comprising:
a bracket member comprising a first support flange, and a second flange, and a junction region having a concave inner surface and a convex outer surface which unitarily joins the first support flange and the second support flange to one another at a substantially right angle; and
a nut plate formed with the first support flange, wherein the nut plate comprises:
(i) a planar nut plate base unitarily molded with the first support flange;
(ii) a cylindrical nut plate boss which extends from and is unitarily formed as a one-piece molded unit with the planar nut plate base;
(iii) a planar supporting web extending radially from the cylindrical nut plate boss and unitarily joining the cylindrical nut plate boss and the first support flange; and
(iv) a metal threaded nut cylinder which is embedded within and overmolded with the cylindrical nut plate boss.

2. The support bracket according to claim 1 , further comprising a third support flange unitarily molded with the second support flange and extends in an opposite direction of the first support flange.

3. The support bracket according to claim 2 , which further comprises a second junction region having a concave inner surface and a convex outer surface which unitarily joins the second support flange and the third support flange to one another at a substantially right angle.

4. The support bracket according to claim 1 , wherein the planar nut base is generally elliptical.

5. The support bracket according to claim 1 , which further comprises right and left side walls integrally joining the first and second support flanges.

6. The support bracket according to claim 5 , wherein the right and left side walls are generally triangularly shaped.

7. The support bracket according to claim 6 , wherein each of the right and left side walls includes a perimeter flange having a generally triangularly shaped lateral edge, and a side wall plate joined to the lateral edge of the perimeter flange.

8. The support bracket according to claim 7 , wherein the side walls generally define a right triangle with respective adjoining right angle legs being integral with the first and second support flanges and a concavely curved hypotenuse leg extending downwardly from the second support flange to a terminal end of the first support flange.

9. The support bracket according to claim 2 , wherein the third support flange includes a pair of lateral convex lobes and a central concave recess between the convex lobes.

10. An aircraft which comprises the support bracket according to claim 1 .

11. A one-piece molded thermoplastic support bracket for supporting wiring, cabling and/or tubing, the support bracket comprising:
a bracket member comprising a first support flange, and a second flange, and a junction region having a concave inner surface and a convex outer surface which unitarily joins the first support flange and the second support flange to one another at a substantially right angle; and
a generally U-shaped wire, cable or tubing mount unitarily formed as a one-piece molded unit with the first support flange so as to dependently extend therefrom, wherein the wire, cable or tubing mount includes:
(i) a generally rectangular base member unitarily formed with the first support flange;
(ii) a pair of laterally spaced apart opposed mounting fingers unitarily formed at each end of the base member so as to define a space therebetween which is adapted to receive wiring, tubing or cabling, and
(iii) generally rectangular apertures formed in each of the mounting fingers and adapted to receive therein a cable tie to thereby connect the wiring, tubing or cabling in the defined space between the mounting fingers to the wire, cable or tubing mount.

12. The support bracket according to claim 11 , further comprising a third support flange unitarily molded with the second support flange and extends in an opposite direction of the first support flange.

13. The support bracket according to claim 12 , which further comprises a second junction region having a concave inner surface and a convex outer surface which unitarily joins the second support flange and the third support flange to one another at a substantially right angle.

14. The support bracket according to claim 11 , which further comprises right and left side walls integrally joining the first and second support flanges.

15. The support bracket according to claim 14 , wherein the right and left side walls are generally triangularly shaped.

16. The support bracket according to claim 15 , wherein each of the right and left side walls includes a perimeter flange having a generally triangularly shaped lateral edge, and a side wall plate joined to the lateral edge of the perimeter flange.

17. The support bracket according to claim 16 , wherein the side walls generally define a right triangle with respective adjoining right angle legs being integral with the first and second support flanges and a concavely curved hypotenuse leg extending downwardly from the second support flange to a terminal end of the first support flange.

18. The support bracket according to claim 11 , wherein the third support flange includes a pair of lateral convex lobes and a central concave recess between the convex lobes.

19. An aircraft which comprises the support bracket according to claim 11 .
