Coupler for towed vehicles
Apparatus, methods, and other examples associated with a hitch ball coupler are described herein. In one example, a coupler includes a body and a cap. The body and cap are pivotally connected on a first end. The body includes a first recess and a shoulder. The cap is selectively moveable between a closed position and an open position. The cap includes a second recess that selectively forms a socket with the first recess, and an arm extending from a second end that engages the shoulder when the cap is in the open position.

a cap having a first end, the cap pivotally coupled to the body at the first end of the cap, the cap being selectively moveable between a closed position and an open position.
2. The coupler assembly of claim 1 , wherein the sleeve is generally circular in cross-section.
3. The coupler assembly of claim 1 , further comprising a tongue having a first portion and a second portion, the first portion coupled to the towed vehicle and the second portion coupled to the sleeve.
4. The coupler assembly of claim 1 , wherein the body includes a first recess and the cap includes a second recess that forms a socket with the first recess.
5. The coupler assembly of claim 1 , wherein the hollow central portion extends an entire length of the sleeve.
6. The coupler assembly of claim 1 , wherein the collar is capable of being slid toward the cap securing the cap in the closed position and capable of being slid away from the cap securing the cap in the open position.
7. A coupler assembly for a towed vehicle, the coupler assembly comprising:
a body capable of being attached to the towed vehicle, the body having a first recess;
a shank extending from the body toward the towed vehicle, the shank having a hollow cross-section; and
a cap pivotally coupled to the body at a first end of the cap and selectively moveable between a closed position and an open position, the cap having a second recess that forms a socket with the first recess.
8. The coupler assembly of claim 7 , wherein the hollow cross-section of the shank is generally circular.
9. The coupler assembly of claim 7 , further comprising a tongue having a first portion and a second portion, the first portion coupled to the towed vehicle and the second portion coupled to the body.
10. The coupler assembly of claim 9 , wherein the shank secures the body to the tongue.
11. The coupler assembly of claim 7 , wherein the shank has a hollow cross section along its entire length between the body and the towed vehicle.
12. The coupler assembly of claim 9 , further comprising a collar mounted to the body, wherein the collar is capable of being slid toward the cap securing the cap in the closed position and capable of being slid away from the cap securing the cap in the open position.
13. The coupler assembly of claim 12 , further comprising an actuating handle having a first portion and a second portion, wherein the first portion is coupled to the collar and the second portion is pivotably coupled to the tongue.
14. The coupler assembly of claim 7 , wherein a collar is mounted to the shank.
15. A coupler assembly for attaching a towed vehicle to a towing vehicle, the coupler assembly comprising:
a body having a rear portion;
a sleeve extending from the rear portion of the body, the sleeve having a hollow cross section;
a shank extending from a rear portion of the sleeve, the shank having a hollow cross section;
a cap pivotally coupled to the body at a first end of the cap and selectively moveable between a closed position and an open position;
a collar mounted to the rear portion of the body; and
a handle operably coupled to the collar, wherein the handle is operable to slide the collar in first and second positions.
16. The coupler assembly of claim 15 , wherein the shank is integrally formed with the body.
17. The coupler assembly of claim 15 , further comprising a tongue having a first portion and a second portion, the first portion coupled to the towed vehicle and the second portion coupled to the sleeve.
18. The coupler assembly of claim 17 , wherein the handle includes a first portion and a second portion wherein the first portion is operably coupled to the collar and the second portion is pivotably mounted on the tongue.
19. The coupler assembly of claim 18 , wherein the handle is operable to slide and hold the collar in either a forward or rearward position.
20. The coupler assembly of claim 17 , wherein the handle is capable of sliding the collar toward the cap securing the cap in the first position and capable of sliding the collar away from the cap securing the cap in the second position.
