Abstract

A hitch alignment device includes two components, one component attached to a first engageable member of a hitch mounted to a car and the second component attached to a second engageable member of the hitch mounted to a trailer. Each component has a rod with a reflector plate removably and adjustably clipped near one end thereof. A base plate is removably clipped near the other end of each rod. Each plate abuts a respective engageable member of the hitch. Each rod has a lock washer attached to one end of a stretchable strap. The stretchable strap has a looped outer end. The strap wraps about the respective engageable member with the looped end thereof positioned at the base plate end of the rod so that the rod extends through the loop to retain the strap in the stretched position. The tension of the strap retains the rod in a fixed position to the engageable member of the hitch. The base plate stabilizes the rod against the engeable member. The rods can be mounted either vertically or horizontally such that reflector plates, when aligned from the driver'"'"'s viewpoint, indicate the two engageable members of the hitch are in a position to be coupled together.

Claims

1. A guide device having two components for aligning first and second engageable hitch members mounted respectively on a vehicle and a trailer, one component includes a first frame mountable on the first engageable member and the second component includes a second frame mountable on the second engageable member;

the improvement comprising;

strap means connected to the first frame and sized to wrap about the first engageable member to tightly strap the frame against the first engageable member;

a base plate having a substantially planar surface and connected to the first frame for abutting the first engageable member at the substantially planar surface; and

a first adjustable means for mounting the base plate to the first frame for adjustment along a length thereof and for angular adjustment about a longitudinal axis thereof.

2. A guide device as defined in claim 1 wherein the first frame comprises a rod including radially extending flanges spaced approximately 90°

apart about a longitudinal axis of the rod;

the first adjustable means includes clip means attached to the base plate for engaging the flanges such that the base plate can be positioned at four fixed positions angularly spaced approximately 90°

apart about the rod and at varying positions longitudinally along the rod.

3. A guide means as defined in claim 2 and further comprising:

first and second sighting elements;

a second adjustable means for adjustably mounting each sighting element to a section of the respective first and second frames along a longitudinal axis thereof and angularly about said longitudinal axis such that the first sighting element can be aligned with the second sighting element when the vehicle and trailer are positioned so the first and second engageable members are positioned for coupling.

4. A guide means as defined in claim 3 wherein the sighting elements comprise a flat plate, the flat plates are connected to the second adjustable means such that when one of the second adjustable means engages the first frame, the flat plate is positioned in one of a transverse or parallel positions relative to the planar surface of the base plate.

5. A guide device as defined in claim 4 wherein the strap means includes:

a washer member with a central aperture through which the rod extends;

a strap member with one end attached to the washer member;

the other end of the strap member having an aperture through which one end of the rod extends;

such that tension exerted by the strap member around the first engageable hitch member locks the washer in place on the rod and fixes the rod to the first engageable hitch member.

6. A guide device as defined in claim 5 wherein the strap member comprises an elastic material.

7. A guide device as defined in claim 6 wherein each component is attached to an engageable hitch member of the hitch by a strap means.

8. A guide device as defined in claim 1 wherein each component is attached to a member of the hitch by strap means.

9. A guide device as defined in claim 1 wherein the strap means comprises an elastic material.

10. A guide device having two components for aligning first and second engageable hitch members mounted respectively on a vehicle and a trailer, one component includes a first frame including a rod mountable on the first engageable member and the second component includes a second frame mountable on the second engageable member;

the improvement comprising;

strap means connected to the first frame and sized to wrap about the first engageable member to tightly strap the frame against the first engageable member, the strap means includes;

a washer member with a central aperture through which the rod extends;

a strap member with one end attached to the washer member;

the other end of the strap member having an aperture through which one end of the rod extends; and

whereby tension exerted by the strap member around the first engageable hitch member locks the washer in place on the rod and fixes the rod to the first engageable hitch member.

11. A guide device as defined in claim 10 wherein the strap member comprises an elastic material.
