Abstract

An article dispensing mechanism for a vending machine includes at least one serpentine track comprised of a pair of facing cusp-shaped vertical panels. These panels are supported on a pair of facing side plates. Each panel has a plurality of projections which extend horizontally from opposite side surfaces of the panel and extend into rectangular-shaped holes formed in both side plates. Each vertical panel is securely fixed on both plates by twisting the outer terminal portion of the projections which extend outwardly from the rectangular-shaped holes.

Claims

1. In an article dispensing mechanism for a vending machine including a pair of side plates facing one another at a predetermined spacing and at least one pair of serial cusp-shaped vertical panels disposed transversely between said side plates, said panels facing each other to define a serpentine track, the improvement comprising said vertical panels having a plurality of projections horizontally extending from each side surface, each side plate having a plurality of elongate holes located so that an outer portion of said projections penetrates and extends through said holes, said projections having an outer edge, and said outer portions of said projections are twisted to place said outer edge of said projections in contact with said side plates and fix said vertical panels to said side plates.

2. The article dispensing mechanism for a vending machine of claim 1 wherein each projection has a narrow width base which interconnects with said panel.

3. The article dispensing mechanism for a vending machine of claim 2 wherein said narrow width base of said projection is formed in a curved configuration.

4. The article dispensing mechanism for a vending machine of claim 1 wherein each projection comprises a trapezoidal-shaped portion and a semicircular shaped base portion.

5. The article dispensing mechanism for a vending machine of claim 1 wherein each vertical panel comprises a plurality of separate cusp-shaped elements.

6. The article dispensing mechanism for a vending machine of claim 1 wherein each vertical panel comprises a plurality of cusp-shaped elements which are integrally formed with one another.

7. The article dispensing mechanism for a vending machine of claim 1 wherein said elongate holes are rectangular.

8. The article dispensing mechanism for a vending machine of claim 2 wherein said outer edge of said projections in the area of said narrow width base contacts an inner surface of said side plates in the twisted position of said projections.

9. The article dispensing mechanism for a vending machine of claim 2 wherein said outer edge of said projections in the area of said narrow width base contacts both an inner and an outer surface of said side plates in the twisted position of said projections.

10. The article dispensing mechanism for a vending machine of claim 3 wherein said outer edge of said projections in the area of said narrow width base contacts an inner surface of said side plates in the twisted position of said projections.

11. The article dispensing mechanism for a vending machine of claim 3 wherein said outer edge of said projections in the area of said narrow width base contacts both an inner and an outer surface of said side plates in the twisted position of said projections.
