Claims
- 1. A change return protection device for installation on the back side of a door to a coin return box of a coin operated machine, said box being connected to a coin return passage having a slotted lower wall comprising:
- a blocking flap shaped to span the full width of said coin return passage and will not block the passage to prevent coins from falling past said blocking flap to be retrieved, said blocking flap prevents the insertion of obstructing material past said coin return door;
- a roughly P-shaped sealing plate, the flat back portion of said sealing plate constituting an attachment area, the rounded portion of said sealing plate being properly dimensioned so that when rigidly attached to said door and said door is opened to allow a user to remove a returned coin said sealing seals off said coin return passage, but allows coins to fall freely into the coin return box when the door is closed; and
- an L-shaped plate to block said slotted lower wall, said L-shaped plate having a V-shaped notch with sharpened edges and being mounted in said coin return box so that said notch points away from said coin return door.
- 2. A change return protection device for installation on the back side of a door to a coin return box of a coin operated machine, said box being connected to a coin return passage having a slotted lower wall, comprising:
- a blocking flap shaped to span the full width of said coin return passage without blocking the passage to prevent coins from falling past said blocking flap to be retrieved, said blocking flap preventing the insertion of obstructing material past said coin return door;
- a roughly P-shaped sealing plate, the flat back portion of said sealing plate constituting an attachment area, the rounded portion of said sealing plate being properly dimensioned so that when rigidly attached to said door and said door is opened to allow a user to remove a returned coin said sealing seals off said coin return passage, but allows coins to fall freely into the coin return box when the door is closed;
- an L-shaped plate to block said slotted lower wall, said L-shaped plate having a V-shaped notch with sharpened edges and an apex and being mounted in said coin return box so that said notch points away from said coin return door, and
- means for bracing said blocking flap and roughly P-shaped sealing plate so that they do not shift in their orientation with respect to one another.
- 3. A change return protection device as in claim 1 wherein said sealing plate is made of a single strip of metal bent to the proper shape.
- 4. A change return protection device as in claim 1 wherein said sealing projection is attached to said attachment area.
- 5. A change return protection device as in claim 1 wherein said sealing projection is solid.
- 6. A change return protection device as in claim 1 wherein said blocking flap and sealing means are made of a single piece of material.
- 7. A change return protection device as in claim 1 wherein said means for preventing the insertion of obstructing material further comprises means for joining said blocking flap to said door.
- 8. A change return protection device as in claim 7 wherein said joining means is a press fit pin fixing said blocking flap to said door.
- 9. A change return protection device as in claim 2 wherein said sealing plate is made of a single strip of metal bent to the proper shape.
- 10. A change return protection device as in claim 2 wherein said sealing projection is attached to said attachment area.
- 11. A change return protection device as in claim 2 wherein said sealing projection is solid.
- 12. A change return protection device as in claim 2 wherein said blocking flap, said sealing means and said bracing means are made from a single piece of material.
