Abstract

An accessory attachment mechanism for a wagon is provided. The mechanism has a mounting bracket, a pivot arm, and a retention mechanism. The mounting bracket is connected to the wagon and has a first opening, a second opening, and a pivot member. The pivot arm is pivotally connected to the mounting bracket at the pivot member and pivots about a plane generally parallel to a base of the wagon between a storage position and a use position. A pin extends through the pivot arm into separate openings in the mounting bracket to retain the pivot arm in the storage and use positions. The retention mechanism is provided at an end of the pivot arm and has a moveable clamp member adapted to secure an accessory thereto.

First claim

What is claimed is:

1. An accessory attachment mechanism for a wagon having a frame, comprising:
a mounting bracket connected to the frame of the wagon, the mounting bracket having a first opening, a second opening, and a pivot member;
a pivot arm having a first end and a second end, the first end of the pivot arm being pivotally connected to the mounting bracket at the pivot member, the pivot arm pivoting between a storage position and a use position;
a pin connected to the pivot arm, the pin having a knob at a first end thereof, the pin extending into the first opening of the mounting bracket when the pivot arm is in the storage position, the pin extending into the second opening of the mounting bracket when the pivot arm is in the use position, and the pin being retractable from the first and second openings to allow the pivot arm to transition therebetween;
an end cap connected to the pivot arm at the first end thereof, the end cap extending beyond the first end of the pivot arm, the end cap having a stop that engages the mounting bracket in the use position to prevent over-rotation of the pivot arm; and,
a retention mechanism at the second end of the pivot arm, the retention mechanism having a moveable clamp member adapted to secure an accessory thereto.

2. The accessory attachment mechanism of claim 1 , wherein the pivot arm pivots about a plane generally parallel to a base of the wagon.

3. The accessory attachment mechanism of claim 1 , wherein the first end and the second end of the pivot arm are adjacent the wagon frame when the pivot arm is in the storage position.

4. The accessory attachment mechanism of claim 1 , wherein the pivot arm is pivoted away from the wagon in the use position.

5. The accessory attachment mechanism of claim 4 , wherein the pivot arm pivots between 40° and 80° when transitioned from the storage position to the use position.

6. The accessory attachment mechanism of claim 1 , wherein the pivot arm has an opening to receive the pin, the opening retaining a spring to bias the pin into the first opening of the mounting bracket and the second opening of the mounting bracket, respectively.

7. The accessory attachment mechanism of claim 1 , wherein the mounting bracket has a bottom plate, and wherein the first opening and second opening of the mounting bracket are provided in the bottom plate of the mounting bracket.

8. The accessory attachment mechanism of claim 1 , wherein the pin connected to the pivot arm extends through the end cap.

9. The accessory attachment mechanism of claim 1 , wherein the clamp member of the retention mechanism is connected to a threaded rod with a knob opposing the clamp member, and wherein turning of the knob in one direction moves the clamp member toward a stationary end of the retention mechanism to clamp an accessory therebetween.

10. An accessory attachment mechanism for a wagon, comprising:
a mounting bracket connected to the wagon, the mounting bracket having a first opening, a second opening, and a pivot member;
a pivot arm having a first end and a second end, the first end of the pivot arm being pivotally connected to the mounting bracket at the pivot member, the pivot arm pivoting about a pivot arm plane generally parallel to a base of the wagon between a storage position and a use position;
a pin extending through the pivot arm entirely about a plane generally parallel to the pivot arm plane and into the first opening of the mounting bracket when the pivot arm is in the storage position, the pin extending into the second opening of the mounting bracket when the pivot arm is in the use position, and the pin being retractable from the first and second openings to allow the pivot arm to transition therebetween, the pin having a flange extending therefrom to operate as a stop against an interior surface of the pivot arm; and,
a retention mechanism at the second end of the pivot arm, the retention mechanism having a moveable clamp member adapted to secure an accessory thereto.

11. The accessory attachment mechanism of claim 10 , further comprising an end cap connected to the pivot arm at the first end thereof, the end cap extending beyond the first end of the pivot arm, the end cap engaging the mounting bracket in the use position to prevent over- rotation of the pivot arm.

12. The accessory attachment mechanism of claim 10 , wherein the mounting bracket is connected to a rear portion of a frame of the wagon.

13. The accessory attachment mechanism of claim 10 , wherein the pivot arm has an opening to receive the pin, the opening retaining a spring to bias the pin into the first opening of the mounting bracket and the second opening of the mounting bracket, respectively, and wherein the pin has a knob at a first end thereof.

14. The accessory attachment mechanism of claim 10 , wherein the clamp member of the retention mechanism is connected to a threaded rod with a knob opposing the clamp member, and wherein turning of the knob in one direction moves the clamp member toward a stationary end of the retention mechanism to clamp an accessory therebetween.

15. An accessory attachment mechanism for a wagon, comprising:
a mounting bracket connected to the wagon, the mounting bracket having a first opening, a second opening, and a pivot member;
a pivot arm having a first end and a second end, the first end of the pivot arm being pivotally connected to the mounting bracket at the pivot member, the pivot arm pivoting between a storage position and a use position, wherein the pivot arm pivots between 40° and 80° when pivoted from the storage position to the use position;
a pin connected to the pivot arm, the pin extending into the first opening of the mounting bracket when the pivot arm is in the storage position, the pin extending into the second opening of the mounting bracket when the pivot arm is in the use position, and the pin being retractable from the first and second openings to allow the pivot arm to transition therebetween;
an end cap connected to the pivot arm at the first end thereof, the end cap extending beyond the first end of the pivot arm, the end cap having a stop that engages the mounting bracket in the use position to prevent over-rotation of the pivot arm; and,
a retention mechanism at the second end of the pivot arm, the retention mechanism having a moveable clamp member adapted to secure an accessory thereto.

16. The accessory attachment mechanism of claim 15 , wherein the pivot arm pivots about a plane generally parallel to a base of the wagon.

17. The accessory attachment mechanism of claim 15 , wherein the mounting bracket is connected to a rear portion of a frame of the wagon.

18. The accessory attachment mechanism of claim 15 , wherein the pivot arm has an opening to receive the pin, the opening retaining a spring to bias the pin into the first opening of the mounting bracket and the second opening of the mounting bracket, respectively, and wherein the pin has a knob at a first end thereof.

19. The accessory attachment mechanism of claim 15 , wherein the clamp member of the retention mechanism is connected to a threaded rod with a knob opposing the clamp member, and wherein turning of the knob in one direction moves the clamp member toward a stationary end of the retention mechanism to clamp an accessory therebetween.
