Abstract

A grab handle mounting assembly securable to a mounting surface includes a first mounting arm assembly securable to a mounting surface. The first mounting arm assembly defines a first male pin. A second mounting arm assembly is securable to a mounting surface and defines a second male pin. The assembly further includes a first tube having first and second open ends, wherein the first male pin is mateable within the first open end of the first tube and the second male pin is mateable within the second open end of the first tube. When the first and second mounting arm assemblies are secured to a mounting surface with the first and second male pins mated with the first and second open ends of the first tube, the first and second mounting arm assemblies impose a torsional force on the first tube.

Claims

1. A grab handle mounting assembly securable to a mounting surface, comprising:

(a) a first mounting arm assembly securable to a mounting surface, the first mounting arm assembly defining a first male pin;

(b) a second mounting arm assembly securable to a mounting surface, the second mounting arm assembly defining a second male pin;

(c) a first tube having first and second open ends, wherein the first male pin is mateable within the first open end of the first tube and the second male pin is mateable within the second open end of the first tube, wherein when the first and second mounting arm assemblies are secured to a mounting surface with the first and second male pins mated with the first and second open ends of the first tube, the first and second mounting arm assemblies impose a torsional force on the first tube.

2. The grab handle assembly of claim 1, wherein the first male pin has first and second opposing helical channels extending along at least a portion the first male pin, and the second male pin has third and fourth opposing helical channels extending along at least a portion the second male pin.

3. The grab handle assembly of claim 2, wherein the first tube has first and second protrusions formed on an interior surface of the first tube near the first open end and third and fourth protrusions formed on an interior surface of the first tube near the second open end, wherein the first male pin is receivable within the first open end of the first tube such that the first and second protrusions are disposed within the first and second helical channels and the second male pin is receivable within the second open end of the first tube such that the third and fourth protrusions are disposed within the third and fourth helical channels.

4. The grab handle assembly of claim 3, wherein the first and second protrusions are formed along first and second axes of the first tube and the third and fourth protrusions are formed along third and fourth axes of the first tube.

5. The grab handle assembly of claim 2, wherein the first and second opposing helical channels are substantially congruent geometrical helical channels and the third and fourth opposing helical channels are substantially congruent geometrical helical channels.

6. The grab handle assembly of claim 1, further comprising:

(a) a third male pin defined on the second mounting arm assembly;

(b) a third mounting arm assembly having a fourth male pin; and

(c) a second tube having first and second open ends, wherein the third male pin is mateable within the first open end of the second tube and the fourth male pin is mateable within the second open end of the second tube, wherein when the second and third mounting arm assemblies are secured to a mounting surface with the third and fourth male pins mated with the first and second open ends of the second tube, the second and third mounting arm assemblies impose a torsional force on the second tube.

7. A grab handle mounting assembly securable to a mounting surface, comprising:

(a) a first mounting arm assembly securable to a mounting surface, the first mounting arm assembly defining a first male pin, the first male pin having first and second opposing helical channels extending along at least a portion the first male pin;

(b) a second mounting arm assembly securable to a mounting surface, the second mounting arm assembly defining a second male pin, the second male pin having third and fourth opposing helical channels extending along at least a portion the second male pin;

(c) a first tube having first and second open ends and first and second protrusions formed on an interior surface of the first tube near the first open end and third and fourth protrusions formed on an interior surface of the first tube near the second open end, wherein the first male pin is receivable within the first open end of the first tube such that the first and second protrusions are disposed within the first and second channels and the second male pin is receivable within the second open end of the first tube such that the third and fourth protrusions are disposed within the third and fourth channels; and

(d) wherein when the first and second mounting arm assemblies are secured to a mounting surface with the first and second male pins received within the first tube, the first and second mounting arm assemblies impose a torsional force on the first tube.

8. The grab handle assembly of claim 7, wherein the first and second protrusions are formed along first and second axes of the first tube and the third and fourth protrusions are formed along third and fourth axes of the first tube.

9. The grab handle assembly of claim 7, wherein the first and second opposing helical channels are substantially congruent geometrical helical channels and the third and fourth opposing helical channels are substantially congruent geometrical helical channels.

10. The grab handle assembly of claim 9, further comprising:

(a) a third male pin defined on the second mounting arm assembly;

(b) a third mounting arm assembly having a fourth male pin; and

(c) a second tube having first and second open ends, wherein the third male pin is mateable within the first open end of the second tube and the fourth male pin is mateable within the second open end of the second tube, wherein when the second and third mounting arm assemblies are secured to a mounting surface with the third and fourth male pins mated with the first and second open ends of the second tube, the second and third mounting arm assemblies impose a torsional force on the second tube.

11. A method of installing a grab handle assembly, the method comprising:

(a) securing a first mounting arm assembly to a mounting surface, the first mounting arm assembly defining a first male pin;

(b) providing a first tube having first and second open ends;

(c) mating the first open end of the first tube with the first male pin;

(d) providing a second mounting arm assembly defining a second male pin;

(e) mating the second male pin within the second open end of the first tube;

(f) securing the second mounting arm assembly to a mounting surface to impose a torsional force on the first tube.

12. The method of claim 11, wherein the first male pin has first and second opposing helical channels extending along at least a portion the first male pin, and the second male pin has third and fourth opposing helical channels extending along at least a portion the second male pin.

13. The method of claim 12, wherein the first tube has first and second protrusions formed on an interior surface of the first tube near the first open end and third and fourth protrusions formed on an interior surface of the first tube near the second open end, wherein the first male pin is receivable within the first open end of the first tube such that the first and second protrusions are disposed within the first and second helical channels and the second male pin is receivable within the second open end of the first tube such that the third and fourth protrusions are disposed within the third and fourth helical channels.

14. The method of claim 13, wherein the first and second protrusions are formed along first and second axes of the first tube and the third and fourth protrusions are formed along third and fourth axes of the first tube.
