Claims
- 1. A coin mechanism comprising
- a cover plate having a coin slot,
- a coin conveyor having a coin recess in alignment with the coin slot when the coin conveyor is in a rest position,
- a handle for rotating the coin conveyor, engaged to a drive gear by a shaft,
- a measuring device for preventing rotation of the handle substantially beyond the rest position unless a coin of the correct size is deposited into the coin recess, and
- a blocking member biased to a rest position retracted from the coin slot and pivotable between the rest position and a blocking position in which the blocking member substantially covers the coin slot, the blocking member cooperating with a rotatable member which forces the blocking member into the blocking position upon rotation of the handle.
- 2. The coin mechanism of claim 1 in which the blocking member comprises a blade extending substantially across the coin slot.
- 3. The coin mechanism of claim 2 in which the blocking member comprises a rocker bar pivotably mounted about the shaft.
- 4. The coin mechanism of claim 3 in which the rocker bar is pivotably mounted about a hub of the rotatable member.
- 5. The coin mechanism of claim 2 in which in the rest position the blade extends into a slot in a stationary back plate fixed to the cover plate, to prevent rotation of the blocking member.
- 6. The coin mechanism of claim 1 in which the blocking member is biased to the rest position by a spring.
- 7. The coin mechanism of claim 1 in which the rotatable member comprises a cam having a rest position adjacent the blocking member, to contact the blocking member upon rotation of the handle.
- 8. The coin mechanism of claim 7 in which the cam projects from a cam disc rotatably fixed to the shaft.
- 9. The coin mechanism of claim 7 in which the cam is provided with a sloped leading portion.
- 10. The coin mechanism of claim 7 in which the cam has a length substantially equal to a length of the coin slot.
- 11. A vending machine having a coin mechanism, the coin mechanism comprising
- a cover plate having a coin slot,
- a coin conveyor having a coin recess in alignment with the coin slot when the coin conveyor is in a rest position,
- a handle for rotating the coin conveyor, engaged to a drive gear by a shaft,
- a measuring device for preventing rotation of the handle substantially beyond the rest position unless a coin of the correct size is deposited into the coin recess, and
- a blocking member biased to a rest position retracted from the coin slot and pivotable between the rest position and a blocking position in which the blocking member substantially covers the coin slot, the blocking member cooperating with a rotatable member which forces the blocking member into the blocking position upon rotation of the handle.
- 12. The vending machine of claim 11 in which the blocking member comprises a blade extending substantially across the coin slot.
- 13. The vending machine of claim 12 in which the blocking member comprises a rocker bar pivotably mounted about the shaft.
- 14. The vending machine of claim 13 in which the rocker bar is pivotably mounted about a hub of the rotatable member.
- 15. The vending machine of claim 12 in which in the rest position the blade extends into a slot in a stationary back plate fixed to the cover plate, to prevent rotation of the blocking member.
- 16. The vending machine of claim 11 in which the blocking member is biased to the rest position by a spring.
- 17. The vending machine of claim 11 in which the rotatable member comprises a cam having a rest position adjacent the blocking member, to contact the blocking member upon rotation of the handle.
- 18. The vending machine of claim 17 in which the cam projects from a cam disc rotatably fixed to the shaft.
- 19. The vending machine of claim 17 in which the cam is provided with a sloped leading portion.
- 20. The vending machine of claim 17 in which the cam has a length substantially equal to a length of the coin slot.
