Abstract

A trailer hitch spring bar cover system for providing clean and safe storage of a trailer weight distribution system including spring bars and towing balls. The cover for a trailer weight distribution spring bar generally includes a first body and a second body movably connected to the first body. Each of the bodies have a first end, a second end, a perimeter edge, a cavity, and a cutout near an end of the body. The cover has an opened state adapted to receive or remove a greased portion of the spring bar. The cover also has a closed state to substantially enclose a greased portion of the spring bar.

Claims (39)

1. A cover for a trailer weight distribution spring bar, comprising:

a first body having a first end, a second end, a perimeter edge a cavity between the first end and the second end of the first body, and a cutout near the second end of the first body;

a second body having a first end, a second end, a perimeter edge, a cavity between the first end and the second end of the second body, and a cutout near the second end;

wherein the second body is movably connected to the first body;

wherein the cover has an opened state wherein the perimeter edges of the first body and the second body are separated sufficiently to partially insert a greased portion of a spring bar into one of the cavities of the first body or the second body;

wherein the cover has a closed state wherein the perimeter edges of the first body and the second body are adjacent one another to form a substantially enclosed receiving cavity comprised of the cavities of the first body and the second body, wherein the receiving cavity is adapted to receive the greased portion of the spring bar when the cover is in the closed state so the cover protects the greased portion of the spring bar, and wherein the cutouts of the first body and the second body form an opening when the cover is in the closed state to allow a portion of the spring bar to extend through the opening outwardly from the cover, and wherein the first ends of the first body and the second body form a closed end when the cover is in the closed state;

wherein the first body and the second body each include a rib extending inwardly, and wherein a channel that holds a portion of the spring bar is formed between the rib of the first body and the rib of the second body when the cover is in the closed state;

and wherein the rib of the first body and the second body are substantially rigid.

2. The cover of claim 1 , wherein the second body is pivotally connected to the first body by a hinge.

3. The cover of claim 2 , wherein the hinge is connected to the respective first ends of the first body and the second body.

4. The cover of claim 2 , wherein the hinge is connected to a side portion of the first body and the second body.

5. The cover of claim 1 , wherein the first body and the second body mirror one another.

6. The cover of claim 1 , wherein the first body and the second body each form half-shells.

7. The cover of claim 1 , wherein the cover is substantially L-shaped.

8. The cover of claim 1 , wherein the cover is substantially longated.

9. The cover of claim 1 , including a seal positioned between the perimeters of the first body and the second body.

10. The cover of claim 1 , including a first seal portion attached to the first cutout of the first body and a second seal portion attached to the second cutout of the second body.

11. The cover of claim 10 , wherein the first seal portion and the second seal portion each have a C-shaped structure adapted to form a seal about a perimeter of the spring bar when the cover is in the closed state.

12. The cover of claim 1 , wherein the first body includes an eyelet.

13. The cover of claim 12 , wherein the second body includes an eyelet, wherein the eyelet of the first body is substantially aligned with the eyelet of the second body to form an opening when the cover is in the closed state.

14. The cover of claim 1 , wherein the rib of the first body and the rib of the second body form a ring shaped structure when the cover is in the closed state.

15. The cover of claim 14 , wherein the rib of the first body and the second body are substantially transverse with respect to a longitudinal axis of the cover.

16. The cover of claim 1 , including a locking member, wherein the locking member is adapted to secure the first body to the second body when in the closed state.

17. The cover of claim 16 , wherein the locking member is comprised of a slide latch.

18. A method of using the cover of claim 1 , comprising:

positioning the cover into the open state;

positioning the first body or the second body about the greased portion of the spring bar;

positioning the cover into the closed state so that the first body and the second body substantially enclose the greased portion of the spring bar.

19. The cover of claim 1 , wherein the first body and the second body each include at least two ribs extending inwardly, and wherein a channel that contacts and holds a portion of the spring bar is formed between the ribs of the first body and the ribs of the second body when the cover is in the closed state.

20. A cover for a trailer weight distribution spring bar, comprising:

a first body having a first end, a second end, a perimeter edge a cavity between the first end and the second end of the first body, and a cutout near the second end of the first body;

a second body having a first end, a second end, a perimeter edge, a cavity between the first end and the second end of the second body, and a cutout near the second end;

wherein the second body is movably connected to the first body;

wherein the cover has an opened state wherein the perimeter edges of the first body and the second body are separated sufficiently to partially insert a greased portion of a spring bar into one of the cavities of the first body or the second body;

wherein the cover has a closed state wherein the perimeter edges of the first body and the second body are adjacent one another to form a substantially enclosed receiving cavity comprised of the cavities of the first body and the second body,

wherein the receiving cavity is adapted to receive the greased portion of the spring bar when the cover is in the closed state so the cover protects the greased portion of the spring bar, and wherein the cutouts of the first body and the second body form an opening when the cover is in the closed state to allow a portion of the spring bar to extend through the opening outwardly from the cover,

wherein the first ends of the first body and the second body form a closed end when the cover is in the closed state; and wherein the first body and the second body each include a rib extending inwardly, and wherein a channel that holds a portion of the spring bar is formed between the rib of the first body and the rib of the second body when the cover is in the closed state; and

wherein the rib of the first body and the rib of the second body form a ring shaped structure when the cover is in the closed state.

21. The cover of claim 20 , wherein the rib of the first body and the second body are substantially transverse with respect to a longitudinal axis of the cover.
