Cover actuated roll towel dispense
Toweling dispenser apparatus includes a cover having relatively moveable cover portions. Relative movement caused by pushing one of the cover portions operates through transmission structure to rotate a toweling support drum and move toweling within the interior of the apparatus toward a dispensing position.
1. Apparatus for dispensing paper toweling from a roll of paper toweling, said apparatus comprising, in combination:
a dispenser housing defining a housing interior and an opening communicating with said housing interior permitting access to said housing interior;
a rotatable, elongated toweling support drum for receiving and supporting paper toweling extending from a roll of paper toweling in said housing interior and for transporting said paper toweling to dispense the paper toweling;
a cover including a first cover portion and a second cover portion, said first cover portion moveable relative to said second cover portion, said cover mounted for movement relative to said housing and selectively movable relative thereto between a closed position wherein said opening is closed by said first and second cover portions and an open position wherein said opening is uncovered; and
transmission structure operatively associated with said cover and said toweling support drum and responsive to movement of said first cover portion relative to said second cover portion when said cover covers said opening to rotate said toweling support drum, said transmission structure including a toothed rack member attached to said first cover portion and extending inwardly therefrom into said housing interior when said cover is in said closed position and a floating gear rotatably mounted on said cover in engagement with said toothed rack member, said toweling support drum having a gear attached thereto, said floating gear moveable between a first position wherein said floating gear is not in engagement with the gear attached to said toweling support drum and a second position wherein said floating gear engages the gear attached to said toweling support drum, said floating gear biased by the force of gravity toward said first position, inward movement of said first cover portion and inward movement of said toothed rack member when the cover is in said closed position moving the floating gear from said first position to said second position and further inward movement of said first cover portion and said toothed rack member after said floating gear engages the gear attached to said toweling support drum causing rotation of said toweling support drum.
2. The apparatus according to claim 1 wherein each of said first and second cover portions includes a front panel, said front panels of said first and second cover portions being pivotally connected.
3. The apparatus according to claim 2 wherein said first cover portion is located below said second cover portion and is supported by said second cover portion.
4. The apparatus according to claim 3 wherein each of said first and second cover portions includes side panels attached to the front panel thereof, the side panels of said first cover portion disposed inwardly of and alongside the side panels of said second cover portion.
5. The apparatus according to claim 1 additionally comprising at least one spring for biasing said first cover portion in a direction away from said dispenser housing when the cover is in said first position.
6. The apparatus according to claim 1 wherein said transmission means includes two toothed rack members attached to the first cover portion and extending inwardly therefrom into said housing interior when said cover is in said closed position, said transmission means including two floating gears rotatably mounted on said cover in engagement with said toothed rack members, said toweling support drum having gears attached at opposed ends thereof in operative engagement with the floating gears rotatably mounted on said cover when said cover in said closed position whereby inward movement of said first cover portion rotates both of said floating gears and the gears attached to the opposed ends of the toweling support drum to effect rotation of said toweling support drum.
7. The apparatus according to claim 1 additionally comprising a nip roller forming a nip with said toweling support drum through which the paper toweling passes during dispensing thereof.
8. The apparatus according to claim 1 wherein said toothed rack member is curved and in continuous engagement with said floating gear during movement of said first cover portion relative to said second cover portion.
9. The apparatus according to claim 1 wherein said cover defines an inclined slot, said floating gear mounted for movement along said slot between said first position and said second position.
10. The apparatus according to claim 1 wherein said floating gear is aligned with the gear attached to the toweling support drum.
